 21 








 Section 2.02 Loans and Borrowings. 
 (a) Borrowings; Several Obligations. Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably
in accordance with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments are several and no Lender shall be
responsible for any other Lender’s failure to make Loans as required. 
 (b) Types of Loans. Subject to
Section 3.03, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or
Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement. 
 (c) Minimum Amounts; Limitation on Number of Borrowings. At the commencement of each Interest Period for any Eurodollar Borrowing,
such Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $5,000,000. 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 or that is required to finance the reimbursement of an LC Disbursement as
contemplated by Section 2.08(e). Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of ten (10) Eurodollar Borrowings outstanding. Notwithstanding any other
provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date. 
 (d) Notes. The Loans made by each Lender shall be evidenced by a single promissory note of the Borrower in substantially the form
of Exhibit A, dated, in the case of (i) any Lender party hereto as of the date of this Agreement, as of the date of this Agreement, (ii) any Lender that becomes a party hereto pursuant to an Assignment and Assumption, as of the effective
date of the Assignment and Assumption, or (iii) any Lender that becomes a party hereto in connection with an increase in the Aggregate Maximum Credit Amounts pursuant to Section 2.06(c), as of the effective date of such increase, payable
to the order of such Lender in a principal amount equal to its Maximum Credit Amount as in effect on such date, and otherwise duly completed. In the event that any Lender’s Maximum Credit Amount increases or decreases for any reason (whether
pursuant to Section 2.06, Section 12.04(b) or otherwise), the Borrower shall deliver or cause to be delivered on the effective date of such increase or decrease, a new Note payable to the order of such Lender in a principal amount equal to
its Maximum Credit Amount after giving effect to such increase or decrease, and otherwise duly completed, and such Lender agrees to promptly thereafter return the previously issued Note held by such Lender marked canceled or otherwise similarly
defaced. The date, amount, Type, interest rate and, if applicable, Interest Period of each Loan made by each Lender, and all payments made on account of the principal thereof, shall be recorded by such Lender on its books for its Note, and, prior to
any transfer, may be endorsed by such Lender on a schedule attached to such Note or any continuation thereof or on any separate record maintained by such Lender. Failure to make 

  

 22 








 
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. 
 (e) Loans and Borrowings under the Existing Credit
Agreement. On the Effective Date (or as soon as practicable with respect to (iii)): 
 (i) the Borrower shall pay all
accrued and unpaid commitment fees, break funding fees under Section 5.02 and all other fees that are outstanding under the Existing Credit Agreement for the account of each “Lender” under the Existing Credit Agreement; 
 (ii) each “ABR Loan” and “Eurodollar Loan” outstanding under the Existing Credit Agreement shall be deemed to be
repaid with the proceeds of a new ABR Loan or Eurodollar Loan, as applicable, under this Agreement; 
 (iii) the
Administrative Agent shall use reasonable efforts to cause such “Lender” under the Existing Credit Agreement to deliver to the Borrower as soon as practicable after the Effective Date the Note issued by the Borrower to it under the
Existing Credit Agreement, marked “canceled” or otherwise similarly defaced; 
 (iv) any letters of credit
outstanding under the Existing Credit Agreement shall be deemed issued under this Agreement; and 
 (v) the Existing Credit
Agreement and the commitments thereunder shall be superceded by this Agreement and such commitments shall terminate. 
 It is the intent of
the parties hereto that this Agreement not constitute a novation of the obligations and liabilities existing under the Existing Credit Agreement or evidence repayment of any such obligations and liabilities and that this Agreement amend and restate
in its entirety the Existing Credit Agreement and re-evidence the obligations of the Borrower outstanding thereunder. 
 Section 2.03
Requests for Borrowings. To request a Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone or by written Borrowing Request in substantially the form of Exhibit B and signed by the Borrower (a

written Borrowing Request. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02: 
 (i) the aggregate amount of the requested Borrowing; 
 (ii) the date of such Borrowing, which
shall be a Business Day; 
  

 23 








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

 (iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period
contemplated by the definition of the term “Interest Period”; 
 (v) the amount of the then effective Borrowing
Base, the current total Revolving Credit Exposures (without regard to the requested Borrowing) and the pro forma total Revolving Credit Exposures (giving effect to the requested Borrowing); and 
 (vi) the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements
of Section 2.05. 
 If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If
no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Each Borrowing Request shall constitute a representation that the
amount of the requested Borrowing shall not cause the total Revolving Credit Exposures to exceed the total Commitments (i.e., the 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 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. 
  

 24 








 (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 
 (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 of the Borrower maintained with the Administrative Agent in New York, New York and designated by the Borrower in the applicable Borrowing Request; provided that ABR
Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.08(e) shall be remitted by the Administrative Agent to the Issuing Bank that made such LC Disbursement. 
  

 25 








 (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.

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 Amounts or the Borrowing Base is terminated or reduced to zero, then the Commitments shall terminate on the effective date of such termination or
reduction.

 (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. 
  

 26 








 (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 or Issuing Bank otherwise consents,
and no such increase shall be permitted if after giving effect thereto the Aggregate Maximum Credit Amounts would exceed $600,000,000; 
 (B) no Default shall have occurred and be continuing at the effective date of such increase; 
 (C) on the effective date of such increase, no Eurodollar Borrowings shall be outstanding or if any Eurodollar Borrowings are outstanding, then the effective date of such increase shall be the last day of the Interest Period in respect of
such Eurodollar Borrowings unless the Borrower pays compensation required by Section 5.02; 
 (D) no Lender’s
Maximum Credit Amount may be increased without the consent of such Lender; 
 (E) if the Borrower elects to increase the
Aggregate Maximum Credit Amounts by increasing the Maximum Credit Amount of a Lender, 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”), together with a processing and recordation fee of $3,500, and the Borrower shall deliver a new Note payable to the order of such Lender in a principal amount equal to its Maximum Credit Amount after
giving effect to such increase, and otherwise duly completed, and such Lender agrees to promptly thereafter return the previously issued Note held by such Lender marked canceled or otherwise similarly defaced; and 
 (F) 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 Borrower and such Additional Lender shall execute and deliver to the Administrative Agent a certificate substantially in the form of Exhibit H-2 (an “Additional Lender Certificate”), together with an
Administrative Questionnaire and a processing and recordation fee of $3,500, and the Borrower shall deliver a Note payable to the order of such Additional Lender in a principal amount equal to its Maximum Credit Amount, and otherwise duly completed.

 (iii) Subject to acceptance and recording thereof pursuant to Section 2.06(c)(iv), from and after the effective date
specified in the Maximum Credit Amount Increase Certificate or the Additional Lender Certificate (or if any Eurodollar Borrowings are outstanding, 

  

 27 








 
then the last day of the Interest Period in respect of such Eurodollar Borrowings, unless the Borrower has paid compensation required by Section 5.02):
(A) the amount of the Aggregate Maximum Credit Amounts shall be increased as set forth therein, and (B) in the case of an Additional Lender Certificate, any Additional Lender party thereto shall be a party to this Agreement and the other
Loan Documents and have the rights and obligations of a Lender under this Agreement and the other Loan Documents. In addition, the Lender or the Additional Lender, as applicable, shall purchase a pro rata portion of the outstanding Loans (and
participation interests in Letters of Credit) of each of the other Lenders (and such Lenders hereby agree to sell and to take all such further action to effectuate such sale) such that each Lender (including any Additional Lender, if applicable)
shall hold its Applicable Percentage of the outstanding Loans (and participation interests) after giving effect to the increase in the Aggregate Maximum Credit Amounts. 
 (iv) Upon its receipt of a duly completed Maximum Credit Amount Increase Certificate or an Additional Lender Certificate, executed by the
Borrower and the Lender or the Borrower and the Additional Lender party thereto, as applicable, the processing and recording fee referred to in Section 2.06(c)(ii), the Administrative Questionnaire referred to in Section 2.06(c)(ii), if
applicable, and the written consent of the Administrative Agent to such increase required by Section 2.06(c)(i), the Administrative Agent shall accept such Maximum Credit Amount Increase Certificate or Additional Lender Certificate and record
the information contained therein in the Register required to be maintained by the Administrative Agent pursuant to Section 12.04(b)(iv). No increase in the Aggregate Maximum Credit Amounts shall be effective for purposes of this Agreement
unless it has been recorded in the Register as provided in this Section 2.06(c)(iv). 
 Section 2.07 Borrowing Base. 

(a) Initial Borrowing Base. For the period from and including the Effective Date to but excluding the initial Redetermination
Date, the amount of the Borrowing Base shall be $280,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from time to time pursuant to Section 2.07(e), Section 8.13(c), Section 9.12 or
Section 9.19. 
 (b) Scheduled and Interim Redeterminations. The Borrowing Base and each portion of the 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 amount shall become effective and applicable to the
Borrower, the Agents, each Issuing Bank and the Lenders on April 1st and October 1st of each year, commencing October 1, 2006. In addition, the Borrower may, by notifying the Administrative Agent thereof, and the Administrative Agent
may, at the direction of the Required Lenders, by notifying the Borrower thereof, one time during 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. 
  

 28 








 (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), (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”), and (C) if applicable, written notice to the
Administrative Agent stating that the Borrower intends to terminate or cancel its position under specific Swap Agreements (“Swap Cancellation Notice”), the Administrative Agent shall evaluate the information contained in the
Engineering Reports and Swap Cancellation Notice, if any, and shall, in good faith, propose a new 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 and consistent with
its normal oil and gas lending criteria as it exists at the particular time. 
 (ii) The Administrative Agent shall notify the
Borrower and the 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) and, if applicable, a Swap Cancellation
Notice 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) and applicable Swap Cancellation Notice in a timely and complete manner, then promptly after the Administrative Agent has received complete Engineering Reports and applicable
Swap Cancellation Notice 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 and applicable Swap Cancellation Notice. 
 (iii) Any Proposed Borrowing Base
that would increase the Borrowing Base then in effect must be approved or deemed to have been approved by the Required Lenders as provided in this Section 2.07(c)(iii); and any Proposed Borrowing Base that would decrease or maintain the
Borrowing Base then in effect must be approved or be deemed to have been approved by the Super-Majority Lenders as provided in this Section 2.07(c)(iii). Upon receipt of the Proposed Borrowing Base Notice, each Lender shall have fifteen
(15) days to agree with the Proposed Borrowing Base or disagree with the Proposed Borrowing Base by proposing an alternate Borrowing Base. If at the end of such fifteen (15) days, any Lender has not 

  

 29 








 
communicated its approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be an approval of the Proposed Borrowing
Base. If, at the end of such 15-day period, the Required Lenders, in the case of a Proposed Borrowing Base that would increase the 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 then in effect, have approved or deemed to have approved, as aforesaid, then the Proposed Borrowing Base shall become the new Borrowing Base, effective on the date specified in Section 2.07(d). If,
however, at the end of such 15-day period, the Required 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 then acceptable to a number of Lenders sufficient to constitute the Required Lenders or the Super-Majority Lenders, in the case of an amount that would decrease or maintain the Borrowing Base, then in effect, for purposes of this
Section 2.07 and such amount shall become the new Borrowing Base, effective on the date specified in Section 2.07(d). 
 (d) Effectiveness of a Redetermined Borrowing Base. After a redetermined Borrowing Base is approved or is deemed to have been approved by the Required Lenders or the Super-Majority Lenders, as applicable, pursuant to
Section 2.07(c)(iii), the Administrative Agent shall notify the Borrower and the Lenders (the “New Borrowing Base Notice”), and such amount (or amounts, as applicable) shall become the new Borrowing Base, effective and
applicable to the Borrower, the Agents, each 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. 
 Such amount shall then become the Borrowing Base until the next Scheduled
Redetermination Date, the next Interim Redetermination Date or the next adjustment, to the extent applicable, under Section 2.07(e), Section 8.13(c), Section 9.12 or Section 9.19 whichever occurs first. Notwithstanding the
foregoing, no Scheduled Redetermination or Interim Redetermination shall become effective until the New Borrowing Base Notice related thereto is received by the Borrower. 
 (e) Reduction of Borrowing Base Upon Issuance of Permitted Debt. Notwithstanding anything to the contrary contained herein, if the
Borrower issues any Permitted Debt during the period between Scheduled Redetermination dates or not in conjunction with an Interim Redetermination, then on the date on which such Permitted Debt is issued, the 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 Permitted Debt. The Borrowing Base as so reduced shall become the new Borrowing Base immediately upon the date of such issuance, 

  

 30 








 
effective and applicable to the Borrower, the Agents, each Issuing Bank and the Lenders on such date until the next redetermination or modification thereof
hereunder. For purposes of this Section 2.07(e), if any such Debt is issued at a discount or otherwise sold for less than “par”, the reduction shall be calculated based upon the stated principal amount without reference to such
discount. 
 Section 2.08 Letters of Credit. 
 (a) General. Subject to the terms and conditions set forth herein, the Borrower may request any Issuing Bank to issue Letters of
Credit for its own account or for the account of any of its Subsidiaries, in a form reasonably acceptable to the Administrative Agent and such Issuing Bank, at any time and from time to time during 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, an 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 any Issuing Bank and the Administrative Agent (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
issued by such Issuing Bank to be amended, renewed or extended; 
 (ii) specifying the date of issuance, amendment, renewal or
extension (which shall be a Business Day); 
 (iii) specifying the date on which such Letter of Credit is to expire (which
shall comply with Section 2.08(c)); 
 (iv) specifying the amount of such Letter of Credit; 
 (v) specifying the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew
or extend such Letter of Credit; and 
 (vi) specifying the amount of the then effective Borrowing Base, 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 

  

 31 








 
Commitments (i.e. the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base). 
 If requested by any Issuing Bank, the Borrower also shall submit a letter of credit application on such Issuing Bank’s standard form in connection
with any request for a Letter of Credit. 
 (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 that issues such Letter of Credit or the
Lenders, each Issuing Bank that issues a Letter of Credit hereunder hereby grants to each Lender, and each Lender hereby acquires from such 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 any Issuing
Bank that issues a Letter of Credit hereunder, such Lender’s Applicable Percentage of each LC Disbursement made by such 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. 
 (e) Reimbursement. If any Issuing
Bank shall make any LC Disbursement in respect of a Letter of Credit issued by such Issuing Bank, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00
noon, New York, New York time, on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., New York, New York time, on such date, or, if such notice has not been received by
the Borrower prior to such time on such date, then not later than 12:00 noon, New York, New York time, on (i) the Business Day that the Borrower receives such notice, if such notice is received prior to 10:00 a.m., New York, New York time, on
the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that if such LC Disbursement is not less than
$1,000,000, the Borrower shall, subject to the conditions to Borrowing set forth herein, be deemed to have requested, and the Borrower does hereby request under such circumstances, that such payment be financed with an ABR Borrowing in an equivalent
amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Borrowing. If the Borrower fails to make such payment when due, the Administrative Agent shall notify
each Lender of the applicable LC Disbursement, the 

  

 32 








 
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 that issued such Letter of Credit 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 that issued such Letter of Credit or, to the extent that Lenders have made
payments pursuant to this Section 2.08(e) to reimburse such Issuing Bank, then to such Lenders and such Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this Section 2.08(e) to reimburse any Issuing Bank
for any LC Disbursement (other than the funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement. 
 (f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in Section 2.08(e) shall be
absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of
Credit, any Letter of Credit Agreement or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein
being untrue or inaccurate in any respect, (iii) payment by any Issuing Bank under a Letter of Credit issued by such Issuing Bank 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 any 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 any Issuing Bank; provided that the foregoing shall not be construed to excuse any 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 such 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 any Issuing Bank (as finally determined by a court of competent
jurisdiction), such 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 that issued such Letter of Credit may, in its sole discretion, either accept and make payment upon such 

  

 33 








 
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. Each Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit issued by such Issuing Bank. Such Issuing Bank shall
promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether such 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 such Issuing Bank and the Lenders with respect to any such LC Disbursement. 
 (h) Interim Interest. If any Issuing Bank shall make any LC Disbursement, then, until the Borrower shall have reimbursed such
Issuing Bank for such LC Disbursement (either with its own funds or a Borrowing under Section 2.08(e)), the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the
date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans. Interest accrued pursuant to this Section 2.08(h) shall be for the account of such Issuing Bank, except that interest accrued on and
after the date of payment by any Lender pursuant to Section 2.08(e) to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment. 
 (i) Replacement of an Issuing Bank. Any Issuing Bank may be replaced or resign at any time by written agreement among the Borrower,
the Administrative Agent, such resigning or replaced Issuing Bank and, in the case of a replacement, the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such resignation or replacement of an Issuing Bank. At the time
any such resignation or replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the resigning or replaced Issuing Bank pursuant to Section 3.05(b). In the case of the replacement of an Issuing Bank,
from and after the effective date of such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the replaced Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and
(ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the resignation or
replacement of an Issuing Bank hereunder, the resigning or replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued
by it prior to such resignation or replacement, but shall not be required to issue additional Letters of Credit. 
 (j)
Cash Collateralization. If (i) any Event of Default shall occur and be continuing and the Borrower receives notice from the Administrative Agent or the Majority Lenders demanding the deposit of cash collateral pursuant to this
Section 2.08(j), or (ii) the Borrower is required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then the Borrower shall deposit, in an
account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to, in the case of an Event of 

  

 34 








 
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 immediately, and such deposit shall become immediately due and payable, without demand or other notice of any
kind, upon the occurrence of any Event of Default with respect to the Borrower or any Subsidiary described in Section 10.01(h) or Section 10.01(i). The Borrower hereby grants to the Administrative Agent, for the benefit of each Issuing
Bank and the Lenders, an exclusive first priority and continuing perfected security interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all
deposits or wire transfers made thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise
payable in respect of, or in exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The Borrower’s obligation to deposit
amounts pursuant to this Section 2.08(j) shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of
Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower or any of its Subsidiaries may now or hereafter have against any
such beneficiary, any Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such deposit shall be held as collateral securing the payment and performance of the Borrower’s and the Guarantor’s
obligations under this Agreement and the other Loan Documents 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 “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, each Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the
satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated, be applied to satisfy other obligations of the Borrower and the Guarantors under this Agreement or
the other Loan Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise required to pay to the Administrative Agent the excess
attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default
have been cured or waived. 
  

 35 








 ARTICLE III 
 Payments of Principal and Interest; Prepayments; Fees 
 Section 3.01 Repayment of Loans. The
Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan on the Termination Date. 
 Section 3.02 Interest. 
 (a) ABR Loans. The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate. 
 (b) Eurodollar Loans. The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest
Period in effect for such Borrowing plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate. 
 (c)
Post-Default Rate. Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower or any Guarantor 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 such Loans as provided in Section 3.02(a)
or Section 3.02(b), as applicable, 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), but in no event to
exceed the Highest Lawful Rate. 
 (d) Interest Payment Dates. Accrued interest on each Loan shall be payable in
arrears on each Interest Payment Date for such Loan and on the Termination Date; provided that (i) interest accrued pursuant to Section 3.02(c) shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan
(other than an optional prepayment of an ABR Loan prior to the Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, and (iii) in the event of any conversion
of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion. 
 (e) Interest Rate Computations. All interest hereunder shall be computed on the basis of a year of 360 days, unless such
computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), except that interest computed by reference to the Alternate Base Rate at times when the
Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last
day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error, and be binding upon the parties hereto. 
  

 36 








 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, on the Business Day 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
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 

  

 37 








 
Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in
Section 2.08(j). 
 (ii) Upon any redetermination of or adjustment to the amount of the Borrowing Base in accordance with
Section 2.07(b) or Section 8.13(c) at any time, if the total Revolving Credit Exposures exceeds the redetermined or adjusted Borrowing Base, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal to
such excess, and (B) if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in
Section 2.08(j). The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral within sixty (60) days following its receipt of the New Borrowing Base Notice in accordance with Section 2.07(d) or the date
the adjustment occurs; provided that all payments required to be made pursuant to this Section 3.04(c)(ii) must be made on or prior to the Termination Date. 
 (iii) Upon any adjustments to the Borrowing Base pursuant to Section 2.07(e), Section 9.12 or Section 9.19, if the total
Revolving Credit Exposures exceeds the Borrowing Base as adjusted, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal to such excess, and (B) if any excess remains after prepaying all of the Borrowings
as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j). The Borrower shall be obligated to make such prepayment and/or
deposit of cash collateral on the date it receives cash proceeds as a result of such disposition or such incurrence of Debt; provided that all payments required to be made pursuant to this Section 3.04(c)(iii) must be made on or prior to the
Termination Date. 
 (iv) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied, first, ratably
to any ABR Borrowings then outstanding, and, second, to any Eurodollar Borrowings then outstanding, and if more than one Eurodollar Borrowing is then outstanding, to each such Eurodollar Borrowing in order of priority beginning with the Eurodollar
Borrowing with the least number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar Borrowing with the most number of days remaining in the Interest Period applicable thereto. 
 (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. 
 (vi) If, at any time, after the receipt by the Borrower or any Subsidiary of net cash proceeds from any disposition of property which disposition would require (whether or not such requirement is waived) the Borrower
or such Subsidiary to make a mandatory prepayment or an offer to repurchase or redeem in respect of any Permitted Debt, then, on the Business Day immediately prior to the date on which such mandatory prepayment or offer in respect of the Permitted
Debt would otherwise become due and payable, the Borrower or such Subsidiary shall make a prepayment (and the Aggregate Maximum Credit Amounts of the 

  

 38 








 
Lenders shall automatically and permanently reduce) in an amount equal to such excess cash proceeds. 
 (d) No Premium or Penalty. Prepayments permitted or required under this Section 3.04 shall be without premium or penalty,
except as required under Section 5.02. 
 Section 3.05 Fees. 
 (a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee, which
shall accrue at the applicable Commitment Fee Rate on the average daily amount of the unused amount of the Commitment of such Lender during the period from and including the date of this Agreement to but excluding the Termination Date. Accrued
commitment fees shall be payable in arrears on the last day of March, June, September and December of each year and on the Termination Date, commencing on the first such date to occur after the date hereof. All commitment fees shall be computed on
the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual number of
days elapsed (including the first day but excluding the last day). 
 (b) Letter of Credit Fees. The Borrower agrees to
pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Margin used to determine the interest rate applicable to
Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later
of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, (ii) to each 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 quarter, and (iii) to each 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 issued by such Issuing Bank or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June,
September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the date of this Agreement; provided that all such fees shall be payable on the Termination Date
and any such fees accruing after the Termination Date shall be payable on demand. Any other fees payable to an Issuing Bank pursuant to this Section 3.05(b) shall be payable within 10 days after demand. All participation fees and fronting fees
shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for
the actual number of days elapsed (including the first day but excluding the last day). 
  

 39 








 (c) Administrative Agent Fees. The Borrower agrees to pay to the Administrative
Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent. 
 (d) Borrowing Base Increase Fees. The Borrower agrees to pay to the Administrative Agent, for the account of each Lender then party to this Agreement, ratably in accordance with its Applicable Percentage, a
Borrowing Base increase fee equal to 0.15% on the amount of any increase of the Borrowing Base over the highest Borrowing Base previously in effect, payable on the effective date of any such increase to the Borrowing Base. 
 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 not be refundable under any circumstances absent manifest error (e.g., as a result of a clerical mistake). 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 an Issuing Bank as expressly provided herein and except that payments pursuant to Section 5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made
directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall
be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All
payments hereunder shall be made in dollars. 
 (b) Application of Insufficient Payments. If at any time insufficient
funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and
fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due
hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties. 
 (c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain
payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations 

  

 40 








 
in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall
purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the
aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is
recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this Section 4.01(c) shall not be construed to apply to any payment made by the
Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any
assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do
so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a
direct creditor of the Borrower in the amount of such participation. 
 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 any 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 such 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 such 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 such 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
Guarantors unto and in favor of the Administrative Agent for the benefit of the Lenders of all of the Borrower’s or each Guarantor’s interest in and to production and all proceeds attributable thereto which may be produced from or
allocated to the Mortgaged Property. The Security Instruments further provide in general for the application of such proceeds to the satisfaction of the Indebtedness and other obligations described therein and secured thereby. Notwithstanding the
assignment contained in such Security Instruments, until 

  

 41 








 
the occurrence of an Event of Default, (a) the Administrative Agent and the Lenders agree that they will neither notify the purchaser or purchasers of
such production nor take any other action to cause such proceeds to be remitted to the Administrative Agent or the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower and its Subsidiaries and (b) the Lenders
hereby authorize the Administrative Agent to take such actions as may be necessary to cause such proceeds to be paid to the Borrower and/or such Subsidiaries. 
 ARTICLE V 
 Increased Costs; Break Funding Payments; Taxes; Illegality 
 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 any 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 such Issuing Bank’s capital or on the capital of such
Lender’s or such 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 such Issuing Bank, to a level
below that which such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuing Bank’s policies and
the policies of such Lender’s or such Issuing Bank’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or such Issuing Bank, as the case may be, such additional amount or amounts
as will compensate such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company for any such reduction suffered. 
 (c) Certificates. A certificate of a Lender or any Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or such 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 such Issuing Bank, as the case may
be, the amount shown as due on any such certificate within 10 days after receipt thereof. 
  

 42 








 (d) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the
part of any Lender or any Issuing Bank to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation; provided that the Borrower shall not
be required to compensate a Lender or an Issuing Bank pursuant to this Section 5.01 for any increased costs or reductions incurred more than 180 days prior to the date that such Lender or such 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 such Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased
costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof. 
 Section 5.02 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an
Event of Default), (b) the conversion of any Eurodollar Loan into an ABR Loan other than on the last day of the Interest Period applicable thereto, 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 5.04(b),
then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined
by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the
period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the
amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other
banks in the eurodollar market. 
 A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this
Section 5.02 and reasonably detailed calculations therefor shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after
receipt thereof. 
 Section 5.03 Taxes. 
 (a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower or any Guarantor under any Loan Document shall be made free and clear of and without deduction for any
Indemnified Taxes or Other Taxes; provided that if the Borrower or any Guarantor shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making
all required deductions (including deductions applicable to additional sums payable under this Section 5.03(a)), the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received
had no such deductions been 

  

 43 








 
made, (ii) the Borrower or such Guarantor shall make such deductions and (iii) the Borrower or such Guarantor shall pay the full amount deducted to
the relevant Governmental Authority in accordance with applicable law. 
 (b) Payment of Other Taxes by the Borrower.
The Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. 
 (c)
Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Lender and each Issuing Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the
Administrative Agent, such Lender or such Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section 5.03) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or
asserted by the relevant Governmental Authority. A certificate of the Administrative Agent, a Lender or an Issuing Bank as to the amount of such payment or liability under this Section 5.03 and reasonably detailed calculations therefor shall be
delivered to the Borrower and shall be conclusive absent manifest error. 
 (d) Evidence of Payments. As soon as
practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower or a Guarantor to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such
Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. 
 (e) Foreign Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the
jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement or any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at
the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate.

 (f) Tax Refunds. If the Administrative Agent or a Lender receives a refund of any Taxes or Other Taxes as to which
it has been indemnified 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 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 

  

 44 








 
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. 
 Section 5.04 Mitigation Obligations. 
 (a) Designation of Different Lending Office. If any Lender requests compensation under Section 5.01, or if the Borrower
is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, then such Lender shall use reasonable efforts to designate a different lending office for funding or
booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable
pursuant to Section 5.01 or Section 5.03, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby
agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. 
 (b) Replacement of Lenders. If (i) any Lender requests compensation under Section 5.01, (ii) 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, (iii) any Lender defaults in its obligation to fund Loans hereunder, or (iv) 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), 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 (A) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (B) 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 (C) in the case of any such assignment resulting from a claim for compensation under Section 5.01 or payments required to be made pursuant to Section 5.03, such
assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the
Borrower to require such assignment and delegation cease to apply. 
 Section 5.05 Illegality. Notwithstanding any other provision of
this Agreement, in the event that it becomes unlawful for any Lender or its applicable lending office to honor its obligation to make or maintain Eurodollar Loans either generally or having a particular Interest Period hereunder, then (a) such
Lender shall promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to make such Eurodollar Loans shall be suspended (the “Affected Loans”) until such time as such Lender may again make
and maintain such Eurodollar Loans and (b) all Affected Loans which would otherwise be made by 

  

 45 








 
such Lender shall be made instead as ABR Loans (and, if such Lender so requests by notice to the Borrower and the Administrative Agent, all Affected Loans of
such Lender then outstanding shall be automatically converted into ABR Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) ABR Loans, all payments of principal which
would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its ABR Loans.

Credit, as applicable, would not conflict with, or cause any Lender or any Issuing Bank to violate or exceed, any applicable Governmental Requirement, and no Change in Law shall have occurred, and no litigation shall be pending or threatened, which
does or, with respect to any threatened litigation, seeks to, enjoin, prohibit or restrain, the making or repayment of any Loan, the issuance, amendment, renewal, extension or repayment of any Letter of Credit or any participations therein or the
consummation of the transactions contemplated by this Agreement or any other Loan Document. 
 (e) The receipt by the
Administrative Agent of a Borrowing Request in accordance with Section 2.03 or a request for a Letter of Credit in accordance with Section 2.08(b), as applicable.

 ARTICLE VII 
 Representations and Warranties 
 The Borrower represents and warrants to the Lenders that:

 Section 7.01 Organization; Powers. Each of the Borrower and the Subsidiaries is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization, has all requisite power and authority, and has all material governmental licenses, authorizations, consents and approvals necessary, to own its assets and to carry on its business as
now conducted, and is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required, except where failure to have such power, authority, licenses, authorizations, consents, approvals and
qualifications could not reasonably be expected to have a Material Adverse Effect. 
 Section 7.02 Authority; Enforceability. The
Transactions are within the Borrower’s and each Guarantor’s corporate powers and have been duly authorized by all necessary corporate and, if required, stockholder action (including, without limitation, any action required to be taken by
any class of directors of the Borrower, whether interested or disinterested, in order to ensure the due authorization of the Transactions). Each Loan Document to which the Borrower and each Guarantor is a party has been duly executed and delivered
by the Borrower and such Guarantor and constitutes a legal, valid and binding obligation of the Borrower and such Guarantor, as applicable, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization,
moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law. 
 Section 7.03 Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or any
other action by, any Governmental Authority or any other third Person (including shareholders or any class of directors, whether interested or disinterested, of the Borrower or any other Person), nor is any such consent, approval, registration,
filing or other action necessary for the validity or enforceability of any Loan Document or the consummation of the transactions contemplated thereby, except such as have been obtained or made and are in full force and effect other than (i) the
recording and filing of the Security Instruments as required by this Agreement and (ii) those third party approvals or consents which, if not made or obtained, would not cause a Default hereunder, could not reasonably be expected to have a
Material Adverse Effect or do not have an adverse effect on the enforceability of the Loan Documents, (b) will not violate any applicable law or regulation or the charter, by-laws or other organizational documents of the Borrower or any
Subsidiary or any order of any Governmental Authority, (c) will not violate or result in a default under any indenture, agreement or other instrument binding upon the Borrower or any Subsidiary or its Properties, or give rise to a right
thereunder to require any payment to be made by the Borrower or such Subsidiary and (d) will not result in the creation or imposition of any Lien on any Property of the Borrower or any Subsidiary (other than the Liens created by the Loan
Documents).

 (a) The Borrower has heretofore furnished to the Lenders its consolidated balance sheet and statements of operations, stockholders’

results of operations and cash flows of the Borrower and its Consolidated Subsidiaries as of such dates and for such periods in accordance with GAAP, subject to year-end audit adjustments and the absence of footnotes in the case of the unaudited

provided for in the Financial Statements. 
 Section 7.05 Litigation. 
 (a) Except as set forth on Schedule 7.05, there are no actions, suits, investigations or proceedings by or before any arbitrator or
Governmental Authority pending against or, to the knowledge of the Borrower, threatened against or affecting the Borrower or any Subsidiary (i) as to which there is a reasonable possibility of an adverse determination that, if adversely
determined, could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect or (ii) that involve any Loan Document or the Transactions. 
 (b) Since the date of this Agreement, there has been no change in the status of the matters disclosed in Schedule 7.05 that,
individually or in the aggregate, has resulted in, or materially increased the likelihood of, a Material Adverse Effect. 
 Section 7.06
Environmental Matters. Except as could not be reasonably expected to have a Material Adverse Effect (or with respect to (c), (d) and (e) below, where the failure to take such actions could not be reasonably expected to have a
Material Adverse Effect): 
 (a) neither any Property of the Borrower or any Subsidiary nor the operations conducted thereon
violate any order or requirement of any court or Governmental Authority or any Environmental Laws. 
 (b) no Property of the
Borrower or any Subsidiary nor the operations currently conducted thereon or, to the knowledge of the Borrower, by any prior owner or operator of such Property or operation, are in violation of or subject to any existing, pending or threatened
action, suit, investigation, inquiry or proceeding by or before any court or Governmental Authority or to any remedial obligations under Environmental Laws. 
  

 50 








 (c) all notices, permits, licenses, exemptions, approvals or similar authorizations, if
any, required to be obtained or filed in connection with the operation or use of any and all Property of the Borrower and each Subsidiary, including, without limitation, past or present treatment, storage, disposal or release of a hazardous
substance, oil and gas waste or solid waste into the environment, have been duly obtained or filed, and the Borrower and each Subsidiary are in compliance with the terms and conditions of all such notices, permits, licenses and similar
authorizations. 
 (d) all hazardous substances, solid waste and oil and gas waste, if any, generated at any and all Property
of the Borrower or any Subsidiary have in the past been transported, treated and disposed of in accordance with Environmental Laws and so as not to pose an imminent and substantial endangerment to public health or welfare or the environment, and, to
the knowledge of the Borrower, all such transport carriers and treatment and disposal facilities have been and are operating in compliance with Environmental Laws and so as not to pose an imminent and substantial endangerment to public health or
welfare or the environment, and are not the subject of any existing, pending or threatened action, investigation or inquiry by any Governmental Authority in connection with any Environmental Laws. 
 (e) the Borrower has taken all steps reasonably necessary to determine and has determined that no oil, hazardous substances, solid waste
or oil and gas waste, have been disposed of or otherwise released and there has been no threatened release of any oil, hazardous substances, solid waste or oil and gas waste on or to any Property of the Borrower or any Subsidiary except in
compliance with Environmental Laws and so as not to pose an imminent and substantial endangerment to public health or welfare or the environment. 
 (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, and the Borrower does not have any reason to
believe that such Property, to the extent subject to the OPA, will not be able to maintain compliance with the OPA requirements during the term of this Agreement. 
 (g) neither the Borrower nor any Subsidiary has any known contingent liability or Remedial Work in connection with any release or
threatened release of any oil, hazardous substance, solid waste or oil and gas waste into the environment. 
 Section 7.07 Compliance with
the Laws and Agreements; No Defaults. 
 (a) Each of the Borrower and each Subsidiary is in compliance with all
Governmental Requirements applicable to it or its Property and all agreements and other instruments binding upon it or its Property, and possesses all licenses, permits, franchises, exemptions, approvals and other governmental authorizations
necessary for the ownership of its Property and 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 Borrower 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 Borrower or a Subsidiary to 

  

 51 








 
Redeem or make any offer to Redeem under any indenture, note, credit agreement or instrument pursuant to which any Material Debt is outstanding or by which
the Borrower or any Subsidiary or any of their Properties is bound. 
 (c) No Default has occurred and is continuing.

 Section 7.08 Investment Company Act. Neither the Borrower nor any Subsidiary is an “investment company” or a company
“controlled” by an “investment company,” within the meaning of, or subject to regulation under, the Investment Company Act of 1940, as amended. 
 Section 7.09 Taxes. Each of the Borrower and its Subsidiaries has timely filed or caused to be filed all Tax returns and reports required to have been filed and has paid or caused to be paid all Taxes required
to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate proceedings and for which the Borrower 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 Adverse Effect. The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of Taxes and other governmental
charges are, in the reasonable opinion of the Borrower, adequate. No Tax Lien has been filed and, to the knowledge of the Borrower, no claim is being asserted with respect to any such Tax or other such governmental charge. 
 Section 7.10 ERISA. 
 (a) The Borrower, the Subsidiaries and each ERISA Affiliate have complied in all material respects with ERISA and, where applicable, the Code regarding each Plan. 
 (b) Each Plan is, and has been, maintained in substantial compliance with ERISA and, where applicable, the Code. 
 (c) No act, omission or transaction has occurred which could result in imposition on the Borrower, 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. 
 (d) No Plan (other than a defined contribution plan) or any
trust created under any such Plan has been terminated since September 2, 1974. No liability to the PBGC (other than for the payment of current premiums which are not past due) by the Borrower, any Subsidiary or any ERISA Affiliate has been or
is expected by the Borrower, any Subsidiary or any ERISA Affiliate to be incurred with respect to any Plan. No ERISA Event with respect to any Plan has occurred. 
 (e) Full payment when due has been made of all amounts which the Borrower, the Subsidiaries or any ERISA Affiliate is required under the
terms of each Plan or applicable law to have paid as contributions to such Plan as of the date hereof, and no accumulated funding deficiency (as defined in section 302 of ERISA and section 412 of the Code), whether or not waived, exists with respect
to any Plan. 
  

 52 








 (f) The actuarial present value of the benefit liabilities under each Plan which is
subject to Title IV of ERISA does not, as of the end of the Borrower’s most recently ended fiscal year, exceed the 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. 
 (g) Neither the Borrower, 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 Borrower, a Subsidiary or any ERISA Affiliate in its sole
discretion at any time without any material liability. 
 (h) Neither the Borrower, the Subsidiaries nor any ERISA Affiliate
sponsors, maintains or contributes to, or has at any time in the six-year period preceding the date hereof sponsored, maintained or contributed to, any Multiemployer Plan. 
 (i) Neither the Borrower, the Subsidiaries nor any ERISA Affiliate is required to provide security under section 401(a)(29) of the Code
due to a Plan amendment that results in an increase in current liability for the Plan. 
 Section 7.11 Disclosure; No Material
Misstatements. The Borrower has disclosed to the Administrative Agent and the Lenders all agreements, instruments and corporate or other restrictions to which it or any of its Subsidiaries is 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. None of the other reports, financial statements, certificates or other information furnished by or on behalf of the Borrower or any Subsidiary to
the Administrative Agent or any Lender or any of their Affiliates in connection with the negotiation of this Agreement or any other Loan Document or delivered hereunder or under any other Loan Document (as modified or supplemented by other
information so furnished) contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that, with
respect to projected financial information, the Borrower represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time. There is no fact peculiar to the Borrower or any Subsidiary which
could reasonably be expected to have a Material Adverse Effect or in the future is reasonably likely to have a Material Adverse Effect and which has not been set forth in this Agreement or the Loan Documents or the other documents, certificates and
statements furnished to the Administrative Agent or the Lenders by or on behalf of the Borrower or any Subsidiary prior to, or on, the date hereof in connection with the transactions contemplated hereby. There are no statements or conclusions in any
Reserve Report or any projections delivered under Section 9.18 which are based upon or include misleading information or fail to take into account material information regarding the matters reported therein, it being understood that projections
concerning volumes attributable to the Oil and Gas Properties and production and cost estimates contained in each Reserve Report or any projections delivered under Section 9.18 are necessarily based upon professional opinions, estimates and
projections and that the Borrower and the Subsidiaries do not warrant that such opinions, estimates and projections will ultimately prove to have been accurate. 
  


 53 








 Section 7.12 Insurance. The Borrower has, and has caused all its Subsidiaries to have,
(a) all insurance policies sufficient for the compliance by each of them with all material Governmental Requirements and all material agreements and (b) insurance coverage in at least amounts and against such risk (including, without
limitation, public liability) that are usually insured against by companies similarly situated and engaged in the same or a similar business for the assets and operations of the Borrower and its Subsidiaries. Schedule 7.12, as of the date hereof,
sets forth a list of all insurance maintained by the Borrower and all its Subsidiaries. The Administrative Agent and the Lenders have been named as additional insureds in respect of such liability insurance policies and the Administrative Agent has
been named as loss payee with respect to Property loss insurance. 
 Section 7.13 Restriction on Liens. Neither the Borrower 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 to grant Liens to the Administrative Agent and the Lenders on or in respect of their Properties to secure the Indebtedness and the Loan Documents, under which all necessary
and appropriate authorizations and consents have been obtained. 
 Section 7.14 Subsidiaries. Except as set forth on Schedule 7.14 or
as disclosed in writing to the Administrative Agent (which shall promptly furnish a copy to the Lenders), which shall be a supplement to Schedule 7.14, the Borrower has no Subsidiaries, each Subsidiary is a Wholly-Owned Subsidiary and the Borrower
has no Foreign Subsidiaries. Neither the Borrower nor any Subsidiary has any Foreign Subsidiaries other than Foreign Subsidiaries permitted by Section 9.15. 
 Section 7.15 Location of Business and Offices. The Borrower’s jurisdiction of organization is Delaware; the name of the Borrower as listed in the public records of Delaware is Bill Barrett Corporation; and
the organizational identification number of the Borrower in Delaware is 3519555 (or, in each case, as set forth in a notice delivered to the Administrative Agent pursuant to Section 8.01(l) in accordance with Section 12.01). The
Borrower’s principal place of business and chief executive offices are located at the address specified in Section 12.01 (or as set forth in a notice delivered pursuant to Section 8.01(l) and Section 12.01(c)). Each
Subsidiary’s jurisdiction of organization, name as listed in the public records of its jurisdiction of organization, organizational identification number in its jurisdiction of organization, and the location of its principal place of business
and chief executive office is stated on Schedule 7.15 (or as set forth in a notice delivered pursuant to Section 8.01(l)). 
 Section
7.16 Properties; Titles, Etc. 
 (a) Except as disclosed in Schedule 7.16, each of the Borrower and the Subsidiaries
has 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, the Borrower or the Subsidiary 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 

  

 54 








 
the Borrower 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 Borrower’s or such Subsidiary’s net revenue interest in such
Property. 
 (b) All material leases and agreements necessary for the conduct of the business of the Borrower 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 Borrower and the Subsidiaries including, without limitation, all easements and rights of way, include all rights and Properties necessary to permit the Borrower 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
Borrower 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 Borrower 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 Borrower 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 Borrower 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 7.17 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) have been
maintained, operated and developed in a good and workmanlike manner and in conformity with all Government 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, (i) 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 (ii) 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 

  

 55 








 
by Government 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
Borrower 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 Borrower or any of its
Subsidiaries, in a manner consistent with the Borrower’s or its Subsidiaries’ past practices (other than those the failure of which to maintain in accordance with this Section 7.17 could not reasonably be expect to have a Material
Adverse Effect). 
 Section 7.18 Gas Imbalances, Prepayments. As of the date hereof, except as set forth on Schedule 7.18 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 Borrower 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 two (2.0) bcf of gas (on an mcf equivalent basis) in the aggregate. 
 Section 7.19 Marketing of Production. Except for contracts listed and in effect on the date hereof on Schedule 7.19, 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 Borrower 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 7.19 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 Borrower’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 7.20 Swap Agreements. Schedule 7.20, as of the date hereof, and after
the date hereof, each report required to be delivered by the Borrower pursuant to Section 8.01(d), sets forth, a true and complete list of all Swap Agreements of the Borrower and each Subsidiary, 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.

 Section 7.21 Use of Loans and Letters of Credit. The proceeds of the Loans and the Letters of Credit shall be used to provide
working capital for exploration and production operations and to provide funding for general corporate purposes of the Borrower and its Subsidiaries, including the acquisition of exploration and production properties. The Borrower and its
Subsidiaries are not 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 

  

 56 








 
part of the proceeds of any Loan or Letter of Credit will be used for any purpose which violates the provisions of Regulations T, U or X of the Board.

 Section 7.22 Solvency. After giving effect to the transactions contemplated hereby, (a) the aggregate assets (after giving
effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement), at a fair valuation, of the Borrower and the Guarantors, taken as a whole, will exceed the aggregate Debt of the Borrower and
the Guarantors on a consolidated basis, as the Debt becomes absolute and matures, (b) each of the Borrower and the Guarantors will not have incurred or intended to incur, and will not believe that it will incur, Debt beyond its ability to pay
such Debt (after taking into account the timing and amounts of cash to be received by each of the Borrower and the Guarantors and the amounts to be payable on or in respect of its liabilities, and giving effect to amounts that could reasonably be
received by reason of indemnity, offset, insurance or any similar arrangement) as such Debt becomes absolute and matures and (c) each of the Borrower and the Guarantors will not have (and will have no reason to believe that it will have
thereafter) unreasonably small capital for the conduct of its business.

accordance with the procedures used in the immediately preceding December 31 Reserve Report. 
 (b) In the event of an

in all material respects and to have been prepared in accordance with the procedures used in the immediately preceding December 31 Reserve Report. For any Interim Redetermination requested by the Administrative Agent or the Borrower pursuant to
Section 2.07(b), the Borrower shall provide such Reserve Report with an “as of” date as required by the Administrative Agent as soon as possible, but in any event no later than 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 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 7.18 with respect to its Oil and Gas Properties evaluated in such Reserve Report which
would require the Borrower or any Subsidiary to deliver Hydrocarbons either generally or produced from such Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor, (iv) none of their Oil and Gas
Properties having a value in excess of $1,000,000 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 required by the Administrative Agent, (v) attached to the certificate is a list of all marketing agreements entered into subsequent to the later of the date hereof or the most recently delivered Reserve Report which
the Borrower could reasonably be expected to have been obligated to list on Schedule 7.19 had such agreement been in effect on the date hereof and (vi) attached thereto is a schedule of the Oil and Gas Properties evaluated by such Reserve
Report that are Mortgaged Properties and demonstrating the percentage of the Borrowing Base that the value of such Mortgaged Properties represent. 
  

 64 








 Section 8.13 Title Information. 
 (a) On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Section 8.12(a), the
Borrower will deliver title information in form and substance reasonably acceptable to the Administrative Agent covering enough of the Oil and Gas Properties evaluated by such Reserve Report that were not included in the immediately preceding
Reserve Report, so that the Administrative Agent shall have received together with title information previously delivered to the Administrative Agent, reasonably satisfactory title information on at least 80% of the total value of the Oil and Gas
Properties evaluated by such Reserve Report. 
 (b) If the Borrower has provided title information for additional Properties
under Section 8.13(a), the Borrower shall, within 60 days of notice from the Administrative Agent that title defects or exceptions exist with respect to such additional Properties, either (i) cure any such title defects or exceptions
(including defects or exceptions as to priority) which are not permitted by Section 9.03 raised by such information, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions except for Excepted Liens (other than
Excepted Liens described in clauses (e), (g) and (h) of such definition) having an equivalent value or (iii) deliver title information in form and substance reasonably acceptable to the Administrative Agent so that the Administrative
Agent shall have received, together with title information previously delivered to the Administrative Agent, reasonably satisfactory title information on at least 80% of the value of the Oil and Gas Properties evaluated by such Reserve Report.

 (c) If the Borrower is unable to cure any title defect requested by the Administrative Agent or the Lenders to be cured
within the 60-day period or the Borrower does not comply with the requirements to provide acceptable title information covering 80% of the value of the Oil and Gas Properties evaluated in the most recent Reserve Report, such default shall not be a
Default, but instead the Administrative Agent and/or the 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 80% requirement, and the Administrative Agent may send a notice to the Borrower and the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as
determined by the Super-Majority Lenders to cause the Borrower to be in compliance with the requirement to provide acceptable title information on 80% of the value of the Oil and Gas Properties. This new Borrowing Base shall become effective
immediately after receipt of such notice. 
 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 

  

 65 








 
80% of such total value, then the Borrower shall, and shall cause its Subsidiaries to, promptly grant to the Administrative Agent as security for the
Indebtedness a first-priority Lien interest (subject only to Excepted Liens of the type described in clauses (a) to (d) and (f) of the definition thereof, 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 such total value. All such Liens will be created and perfected by and in
accordance with the provisions of deeds of trust, security agreements and financing statements or other Security Instruments, all in form and substance reasonably satisfactory to the Administrative Agent and in sufficient executed (and acknowledged
where necessary or appropriate) counterparts for recording purposes. In order to comply with the foregoing, if any 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 Borrower shall promptly cause each Domestic Subsidiary (other than any Subsidiary
classified as such based on the Borrower or any Subsidiary being a general partner thereof, unless such Subsidiary is a Wholly-Owned Subsidiary) to guarantee the Indebtedness pursuant to the Guaranty Agreement. In connection with any such guaranty,
the Borrower shall, or shall cause such Domestic Subsidiary to, (A) execute and deliver a supplement to the Guaranty Agreement executed by such Domestic Subsidiary, (B) pledge all of the Equity Interests of such Domestic Subsidiary
(including, without limitation, delivery of original stock certificates evidencing the Equity Interests of such Domestic Subsidiary, together with an appropriate undated stock powers for each certificate duly executed in blank by the registered
owner thereof) and (C) execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent. 
 (c) In the event that the Borrower or any Domestic Subsidiary becomes the owner of a Foreign Subsidiary, then the Borrower shall, or shall
cause such Domestic Subsidiary to (A) execute and deliver a supplement to the Guaranty Agreement executed by the Borrower or such Domestic Subsidiary, (B) pledge 65% of all the Equity Interests of such Foreign Subsidiary (including,
without limitation, delivery of original stock certificates evidencing such Equity Interests of such Foreign Subsidiary, together with appropriate stock powers for each certificate duly executed in blank by the registered owner thereof) and
(C) execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent. 
 (d) The Borrower will at all times cause the other material tangible and intangible assets of the Borrower and each Subsidiary to be
subject to a Lien of the Security Instruments. 
 (e) Any Person that must guarantee the Indebtedness in order for the
Borrower to be in compliance with Section 9.04(b)(ii)(A)(4) shall guarantee the Indebtedness pursuant to the Guaranty Agreement. In connection with any such guaranty, the Borrower shall, or shall cause such Person to, promptly, but in any event
no later than 30 days after the date required thereby, (A) execute and deliver a supplement to the Guaranty Agreement executed by such Person, and (B) execute and deliver such other additional closing documents, certificates and legal
opinions as shall reasonably be requested by the Administrative Agent. If at any time 

  

 66 








 
such Person is not otherwise required to guarantee the Indebtedness hereunder (whether pursuant to the other provisions of this Section 8.14 or
otherwise) or under any other Loan Document, then upon receipt by the Administrative Agent of evidence satisfactory to it that such Person has been fully and finally released from its guarantee obligations in respect of the Permitted Debt, such
person shall be released from its guarantee obligations with respect to the Indebtedness and the Administrative Agent shall, at the sole cost and expense of the Borrower, execute such further documents and do all such further acts so as to
reasonably evidence such release. 
 Section 8.15 ERISA Compliance. The Borrower will promptly furnish and will cause the Subsidiaries
and any ERISA Affiliate to promptly furnish to the Administrative Agent (i) 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, (ii) 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
Borrower, 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
(iii) 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 Borrower 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 9.18 Swap Agreements. The Borrower will not, and will
not permit any Subsidiary to, enter into any Swap Agreements with any Person other than (a) Swap Agreements in respect of (x) crude oil (i) with an Approved Counterparty and (ii) the notional volumes for which do not exceed, for
the three-year period following the date such Swap Agreement is executed, 70% of the reasonably anticipated projected crude oil production from proved, probable and possible Oil and Gas Properties; and for periods thereafter, 90% of the reasonably
anticipated projected crude oil production from proved developed, producing Oil and Gas Properties and (y) natural gas (i) with an Approved Counterparty and (ii) the notional volumes for which do not exceed, for the three-year period
following the date such Swap Agreement is executed, 70% of the reasonably anticipated projected natural gas production from proved, probable and possible Oil and Gas Properties; and for periods thereafter, 90% of the reasonably anticipated projected
natural gas production from proved developed, producing Oil and Gas Properties (such projections to be adjusted as follows: (A) Oil and Gas Properties evaluated in the most recently delivered Reserve Report shall reflect the actual historical
decline profile of such Oil and Gas Properties and (B) Oil and Gas Properties not evaluated in the most recently delivered Reserve Report shall reflect a reasonable decline profile based upon actual historical decline profiles of similar or
analogous Oil and Gas Properties) for each month during the period during which such Swap Agreement is in effect for each of crude oil and natural gas, calculated separately, provided, however, that for purposes of this Section 9.19(a), put
options and price floors for crude oil and natural gas shall be disregarded; (b) Swap Agreements in respect of interest rates with an Approved Counterparty, as follows: (i) Swap Agreements effectively converting interest rates from fixed
to floating, the notional amounts of which (when aggregated with all other Swap Agreements of the Borrower and its Subsidiaries then in effect effectively converting interest rates from fixed to floating) do not exceed 50% of the then outstanding
principal amount of the Borrower’s Debt for borrowed money which bears interest at a fixed rate and (ii) Swap Agreements effectively converting interest rates from floating to fixed, the notional amounts of which (when aggregated with all
other Swap Agreements of the Borrower and its Subsidiaries then in effect effectively converting interest rates from floating to fixed) do not exceed 75% of the then outstanding principal amount of the Borrower’s Debt for borrowed money which
bears interest at a floating rate; and (c) Swap Agreements permitted under (a) and (b) which are otherwise in compliance with the Borrower’s current hedging policies which have 

  

 76 








 
been in effect prior to the Effective Date or which are thereafter approved in accordance with the policies and procedures authorized by the Borrower’s
board of directors from time to time. In no event shall any Swap Agreement contain any requirement, agreement or covenant for the Borrower or any Subsidiary to post collateral or margin to secure their obligations under such Swap Agreement or to
cover market exposures except to the extent permitted by Section 9.03(d). Concurrently with the delivery of each Reserve Report, the Borrower will furnish a projection of its reasonably anticipated projection of natural gas and crude oil (which
shall reflect the adjustments referred to above) for the 36-month period commencing with the end of the calendar month during which the associated Reserve Report is delivered. The Borrower may supplement or update such projections at any time
without any obligation to do so (but subject to the representation contained in Section 7.11). During any quarterly period, the aggregate notional volumes of all Swap Agreements which were in effect during such period (other than basis
differential swaps) for each of natural gas and crude oil shall not exceed the actual production volumes for each of natural gas and crude oil during such period. 
 Section 9.19 Swap Agreement Termination. Except upon the terms provided under Section 2.07(c), the Borrower shall maintain the hedged positions established pursuant to Swap Agreements used to calculate the
then effective Borrowing Base 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; provided that notwithstanding the foregoing, the Borrower may assign, terminate or unwind Swap Agreements with the effect of canceling its position
if it provides not less than 10 Business Days prior written notice of such intent to the Administrative Agent and the Lenders, and concurrently with such notice the Super-Majority Lenders shall have the right to adjust the Borrowing Base by giving
written notice to the Borrower to reflect the effect on the Borrowing Base of such action.

appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof and the other Loan Documents,
together with such actions and powers as are reasonably incidental thereto. 
 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, (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 Borrower 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 Borrower or a Lender, and shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement
or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or under any other Loan Document or in connection herewith or therewith, (iii) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth herein or in any other Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or
document, (v) the satisfaction of any condition set forth in ARTICLE VI or elsewhere herein, other than to confirm receipt of items expressly 

  

 80 








 
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 Borrower and its Subsidiaries or any other obligor or guarantor, or (vii) any failure by the Borrower or
any other Person (other than itself) to perform any of its obligations hereunder or under any other Loan Document or the performance or observance of any covenants, agreements or other terms or conditions set forth herein or therein. 
 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 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 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
Agent 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 Borrower, the Lenders and each 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 

  

 81 








 
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 or Removal 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, each Issuing Bank and the Borrower, and any Agent may be removed at any time with or without cause by the Majority
Lenders. Upon any such resignation or removal, the Majority Lenders shall have the right, 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 or removal of the
retiring Agent, then the retiring Agent may, on behalf of the Lenders and each 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. The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Agent’s resignation hereunder, the provisions of
this ARTICLE XI and 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 Borrower or any
Subsidiary or other Affiliate thereof as if it were not an Agent hereunder. 
 Section 11.08 No Reliance. Each Lender acknowledges
that it has, independently and without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis 

  

 82 








 
and decision to enter into this Agreement and each other Loan Document to which it is a party. Each Lender also acknowledges that it will, independently and
without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under
or based upon this Agreement, any other Loan Document, any related agreement or any document furnished hereunder or thereunder. The Agents shall not be required to keep themselves informed as to the performance or observance by the Borrower or any
of its Subsidiaries of this Agreement, the Loan Documents or any other document referred to or provided for herein or to inspect the Properties or books of the Borrower or its Subsidiaries. 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 Arrangers shall have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs,
financial condition or business of the Borrower (or any of its Affiliates) which may come into the possession of 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 each 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 each
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 9.12 or is otherwise authorized by the terms of the Loan Documents. 
 Section 11.10 The Arrangers, the Syndication Agent and the Documentation Agents. The Arrangers, 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, any 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, each Issuing Bank and the Lenders hereunder and under the other Loan Documents are
cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective
unless the same shall be permitted by Section 12.02(b), and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan
or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the 

  

 84 








 
Administrative Agent, any Lender or any 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 Borrower and the Majority Lenders or by the Borrower and the Administrative Agent with the consent of the Majority Lenders; provided that no such agreement shall
(i) increase the Maximum Credit Amount of any Lender without the written consent of such Lender, (ii) increase the Borrowing Base without the written consent of the Required Lenders, decrease or maintain the Borrowing Base without the
consent of the Super-Majority Lenders, or modify Section 2.07 without the consent of each Lender, (iii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable
hereunder, or reduce any other Indebtedness hereunder or under any other Loan Document, without the written consent of each Lender affected thereby, (iv) postpone the scheduled date of payment of the principal amount of any Loan or LC
Disbursement, or any interest thereon, or any fees payable hereunder, or any other Indebtedness hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date without
the written consent of each Lender affected thereby, (v) change Section 4.01(b) or Section 4.01(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender,

or (viii) change any of the provisions of this Section 12.02(b) or the definitions of “Required Lenders”, “Super-Majority Lenders” or “Majority Lenders” or any other provision hereof specifying the number or

provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, any other Agent or any Issuing Bank hereunder or under any other Loan Document without the prior written consent of the
Administrative Agent, such other Agent or such Issuing Bank, as the case may be. Notwithstanding the foregoing, any supplement to Schedule 7.14 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental
schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders. 
 Section
12.03 Expenses, Indemnity; Damage Waiver. 
 (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses
incurred by the Administrative Agent and its Affiliates, including, without limitation, the reasonable fees, charges and disbursements of counsel and other outside consultants for the Administrative Agent, the reasonable travel, photocopy, mailing,
courier, telephone and other similar expenses, and the cost of environmental audits and surveys and appraisals, in connection with the syndication of the credit facilities provided for herein, the preparation, negotiation, execution, delivery and

HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES AND RELATED EXPENSES, INCLUDING THE FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH,
OR AS A RESULT OF (i) THE EXECUTION OR DELIVERY OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY OR THEREBY, 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 BORROWER OR ANY SUBSIDIARY TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT,

THE NON-COMPLIANCE, NON-DELIVERY OR OTHER IMPROPER PRESENTATION OF THE DOCUMENTS PRESENTED IN CONNECTION THEREWITH, (v) ANY OTHER ASPECT OF THE LOAN DOCUMENTS, (vi) THE OPERATIONS OF THE BUSINESS OF THE BORROWER AND ITS SUBSIDIARIES BY

indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against such Agent or such Issuing Bank in its
capacity as such. 
 (d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any
claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan

 (f) Notwithstanding any other provisions of this Section 12.03, no transfer or assignment of the interests or obligations of any Lender or any grant of participations therein shall be permitted if such transfer,
assignment or grant would require the Borrower and the Guarantors to file a registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any state. 
 Section 12.04 Successors and Assigns. 
 (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of any Issuing Bank that
issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the
Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section 12.04. Nothing in this Agreement, expressed or implied,
shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of any Issuing Bank that issues any Letter of Credit), Participants (to the extent
provided in Section 12.04(c)) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, each Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this
Agreement. 
 (b) (i) Subject to the conditions set forth in Section 12.04(b)(ii), any Lender may assign to one or more
assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of:

 (A) the Borrower, provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate
of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, to any other assignee; and 
 (B)
the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment to an assignee that is a Lender immediately prior to giving effect to such assignment. 
  

 88 








 (ii) Assignments shall be subject to the following additional conditions: 
 (A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the
assigning Lender’s Commitment, the amount of the Commitment 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, and the Commitments of any assigning Lender remaining a party hereto after giving effect to the assignment shall be at least $5,000,000, unless, in each case, each of the Borrower and the Administrative
Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing; 
 (B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement; 
 (C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a
processing and recordation fee of $3,500; 
 (D) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire and shall deliver notice of the Assignment and Assumption to the Borrower; and 
 (E) in the case of an assignment to a CLO, the assigning Lender shall retain the sole right to approve any amendment, modification or waiver of any provision of this Agreement, provided that the Assignment and Assumption between such Lender
and such CLO may provide that such Lender will not, without the consent of such CLO, agree to any amendment, modification or waiver described in the first proviso to Section 12.02 that affects such CLO. 
 (iii) Subject to Section 12.04(b)(iv) and the acceptance and recording thereof, from and after the effective date specified in each
Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender
thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights
and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 5.01, Section 5.02, Section 5.03 and Section 12.03). Any assignment or transfer by a
Lender of rights or obligations under this Agreement that does not comply with this Section 12.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with
Section 12.04(c). 
 (iv) The Administrative Agent, acting for this purpose as 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 

  

 89 








 
the Maximum Credit Amount of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time
(the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, each 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, any Issuing Bank and any Lender, at any reasonable time and from time to time
upon reasonable prior notice. In connection with any changes to the Register, if necessary, the Administrative Agent will reflect the revisions on Annex I and forward a copy of such revised Annex I to the Borrower, each Issuing Bank and each Lender.

 (v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the
assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in this Section 12.04(b) and any written consent to such assignment required by
this Section 12.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been
recorded in the Register as provided in this Section 12.04(b). 
 (c) (i) Any Lender may, without the consent of the
Borrower, the Administrative Agent or any Issuing Bank, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including
all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for
the performance of such obligations and (C) the Borrower, the Administrative Agent, each 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 or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any
provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the proviso to Section 12.02 that
affects such Participant. In addition such agreement must provide that the Participant be bound by the provisions of Section 12.03. Subject to Section 12.04(c)(ii), the Borrower agrees that each Participant shall be entitled to the
benefits of Section 5.01, Section 5.02 and Section 5.03 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.04(b). To the extent permitted by law, each Participant also
shall be entitled to the benefits of Section 12.08 as though it were a Lender, provided such Participant agrees to be subject to Section 4.01(c) as though it were a Lender. 
 (ii) A Participant shall not be entitled to receive any greater payment under Section 5.01 or Section 5.03 than the applicable
Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a
Foreign Lender if it were a Lender shall not be entitled to the benefits 

  

 90 








 
of Section 5.03 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the
Borrower, to comply with Section 5.03(e) as though it were a Lender. 
 (d) Any Lender may at any time pledge or assign a
security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section 12.04(d) shall not apply to
any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a
party hereto. 
 Section 12.05 Survival; Revival; Reinstatement. 
 (a) All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments
delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans
and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, any other Agent, any Issuing Bank or any Lender may have had notice or knowledge
of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable
under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Section 5.01, Section 5.02, Section 5.03 and Section 12.03 and
ARTICLE XI shall survive and remain in full force and effect 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 Borrower shall take such action as may be
reasonably requested by the Administrative Agent and the Lenders to effect such reinstatement. 
  

 91 








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

 (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.

 (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

 93 








 
OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (iv) ACKNOWLEDGES THAT IT HAS
BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 12.09. 
 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, each Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its
Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information
and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations (including rules and regulations of self-regulatory bodies) or by
any subpoena or similar legal process, (d) to any other party to this Agreement or any other Loan Document, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding
relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section 12.11, to (i) any assignee
of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any Swap Agreement relating to the Borrower and
its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section 12.11 or (ii) becomes available to the
Administrative Agent, any Issuing Bank or any Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of this Section 12.11, “Information” means all information received from the Borrower or
any Subsidiary relating to the Borrower or any Subsidiary and their businesses, other than any such information that is available to the Administrative Agent, any Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the
Borrower or a Subsidiary; provided that, in the case of information received from the Borrower or any Subsidiary after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain
the confidentiality of Information as provided in this Section 12.11 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as
such Person would accord to its own confidential information. 
 Section 12.12 Interest Rate Limitation. It is the intention of the
parties hereto that each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under laws applicable to it (including the laws of the United States of
America and the State of New York or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any of the


  

 94 








 
Loan Documents or any agreement entered into in connection with or as security for the Notes, it is agreed as follows: (i) the aggregate of all
consideration which constitutes interest under law applicable to any Lender that is contracted for, taken, reserved, charged or received by such Lender under any of the Loan Documents or agreements or otherwise in connection with the Notes shall
under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent
that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Borrower); and (ii) in the event that the maturity of the Notes is accelerated by reason of an election of the holder
thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than
the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid,
shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Borrower). All sums paid
or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and spread throughout the stated term of the Loans
evidenced by the Notes until payment in full so that the rate or amount of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and from time to time (i) the amount of
interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant to this Section 12.12 and (ii) in respect of any subsequent interest computation period the amount of interest
otherwise payable to such Lender would be less than the amount of interest payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then the amount of interest payable to such Lender in respect of such subsequent
interest computation period shall continue to be computed at the Highest Lawful Rate applicable to such Lender until the total amount of interest payable to such Lender shall equal the total amount of interest which would have been payable to such
Lender if the total amount of interest had been computed without giving effect to this Section 12.12. 
 Section 12.13 EXCULPATION
PROVISIONS. EACH OF THE PARTIES HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS; THAT IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE
NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS
AGREEMENT AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING 

  

 95 








 
THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF
ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.” 
 Section 12.14 No Third Party Beneficiaries. This Agreement, the other Loan Documents, and the agreement of the Lenders to make Loans and each
Issuing Bank to issue, amend, renew or extend Letters of Credit hereunder are solely for the benefit of the Borrower, and no other Person (including, without limitation, any Subsidiary of the Borrower, any obligor, contractor, subcontractor,
supplier or materialman) shall have any rights, claims, remedies or privileges hereunder or under any other Loan Document against the Administrative Agent, any other Agent, any Issuing Bank or any Lender for any reason whatsoever. There are no third
party beneficiaries. 
 Section 12.15 USA Patriot Act Notice. Each Lender hereby notifies the Borrower that pursuant to the
requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes
the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act.
