 CREDIT AGREEMENT, dated as of April 12, 2012, among Endeavour International
Corporation, a Nevada corporation (“Holdings”), Endeavour Energy UK Limited, a private limited company organized under the laws of England and Wales (the “Borrower”), the Lenders party hereto from time to time and
Cyan Partners, LP, as Administrative Agent. All capitalized terms used herein and defined in Section 1 are used herein as therein defined. 
 W I T N E S S E T H: 
 WHEREAS, subject to and upon the terms and conditions set forth herein, the Lead Arranger has arranged, and the Lenders are willing to make available to the Borrower, the senior secured revolving loan
facility provided for herein; 
 NOW, THEREFORE, IT IS AGREED: 

SECTION 1. Definitions and Accounting Terms. 
 1.01. Defined Terms. As used in this Agreement, the following terms shall have the following meanings (such meanings to be equally applicable to both the singular and plural forms of the terms
defined): 
 “5.5% Convertible Notes” means the 5.5% Convertible Senior Notes due 2016 issued by Holdings,
including any related notes, guarantees, instruments and agreements executed in connection therewith. 
 “11.5%
Convertible Bonds” means the 11.5% Guaranteed Convertible Bonds due 2014 (extended to 2016) issued by Endeavour Energy Luxembourg S.a.r.l. and guaranteed by Holdings, including any related notes, guarantees, instruments and agreements
executed in connection therewith. 
 “12% Senior Subordinated Notes” means the 12% Senior Subordinated Notes
due 2014 issued by Holdings, including any related notes, guarantees, instruments and agreements executed in connection therewith. 
 “Additional Assets” shall mean: 
 (1) any properties or assets
used or useful in the Oil and Gas Business, other than Indebtedness or Capital Stock; 
 (2) the Capital Stock of a Person that
becomes a Restricted Subsidiary as a result of the acquisition of such Capital Stock by Holdings or any of its Restricted Subsidiaries; or 
 (3) Capital Stock constituting a Minority Interest in any Person that at such time is a Restricted Subsidiary; 
 provided, however, that any such Restricted Subsidiary described in clause (2) or (3) is primarily engaged in the Oil and Gas Business. 

  
 1 








 “Additional Guarantor Requirement” shall have the meaning provided in
Section 7.12(c). 
 “Additional Lender” shall have the meaning provided in
Section 2.11. 
 “Additional Security Documents” shall have the meaning provided in
Section 7.12(a). 
 “Adjusted Consolidated Net Tangible Assets” of a specified Person shall mean
(without duplication), as of the date of determination, the remainder of: 
 (1) the sum of: 

(a) discounted future net revenue from proved crude oil and natural gas reserves of such Person and its Restricted Subsidiaries
calculated in accordance with SEC guidelines before any state or federal or other income taxes, as estimated by such Person in a reserve report prepared as of the end of the then most recently ended fiscal year of such Person for which audited
financial statements are available, as increased by, as of the date of determination, the estimated discounted future net revenue from: 
 (i) estimated proved crude oil and natural gas reserves of such Person and its Restricted Subsidiaries attributable to acquisitions consummated since the date of such reserve report, which reserves were
not reflected in such reserve report, and 
 (ii) estimated crude oil and natural gas reserves of such Person and its Restricted
Subsidiaries attributable to extensions, discoveries and other additions and upward revisions of estimates of proved crude oil and natural gas reserves (including previously estimated development costs incurred during the period and the accretion of
discount since the prior period end) due to exploration, development or exploitation, production or other activities which would, in accordance with standard industry practice, cause such revisions, 

in each case calculated in accordance with SEC guidelines (utilizing the prices utilized in such Person’s year end reserve report),

 and decreased by, as of the date of determination, the estimated discounted future net revenue attributable to: 

(A) estimated proved crude oil and natural gas reserves of such Person and its Restricted Subsidiaries reflected in such reserve report
produced or disposed of since the date of such reserve report, and 
 (B) reductions in the estimated crude oil and natural gas
reserves of such Person and its Restricted Subsidiaries reflected in such reserve report since the date of such reserve report due to changes in geological conditions or other factors which would, in accordance with standard industry practice, cause
such revisions, in the case of clauses (A) and (B) calculated in accordance with SEC guidelines (utilizing the prices utilized in such Person’s year end reserve report); 

provided, however, that, in the case of each of the determinations made pursuant to clauses (i) and (ii) above,
such increases and decreases shall be estimated by Holdings’ petroleum engineers or any independent petroleum engineers engaged by Holdings for that purpose; 

  
 2 








 (b) the capitalized costs that are attributable to crude oil and natural gas properties of
such Person and its Restricted Subsidiaries to which no proved crude oil and natural gas reserves are attributable, based on such Person’s books and records as of a date no earlier than the date of such Person’s latest available annual or
quarterly financial statements; 
 (c) the Net Working Capital of such Person as of a date no earlier than the date of such
Person’s latest available annual or quarterly financial statements; and 
 (d) the greater of: 

(i) the net book value of other tangible assets of such Person and its Restricted Subsidiaries as of a date no earlier than the date of
such Person’s latest available annual or quarterly financial statements, and 
 (ii) the appraised value, as estimated by
independent appraisers, of other tangible assets of such Person and its Restricted Subsidiaries as of a date no earlier than the date of such Person’s latest available annual or quarterly financial statements (provided that such Person
shall not be required to obtain such an appraisal of such assets solely for the purpose of determining this value); 
 minus

 (2) the sum of: 
 (a) Minority Interests; 
 (b) to the extent not otherwise taken into account in
determining Adjusted Consolidated Net Tangible Assets, any net natural gas balancing liabilities of such Person and its Restricted Subsidiaries reflected in such Person’s latest audited financial statements; 

(c) to the extent included in clause (1)(a) above, the discounted future net revenue, calculated in accordance with SEC guidelines
(utilizing the prices utilized in such Person’s year end reserve report), attributable to reserves subject to participation interests, overriding royalty interests or other interests of third parties, pursuant to participation, partnership,
vendor financing or other agreements then in effect, or which otherwise are required to be delivered to third parties; 
 (d) to
the extent included in clause (1)(a) above, the discounted future net revenue calculated in accordance with SEC guidelines (utilizing the prices utilized in such Person’s year end reserve report), attributable to reserves that are required
to be delivered to third parties to fully satisfy the obligations of such Person and its Restricted Subsidiaries with respect to Volumetric Production Payments on the schedules specified with respect thereto; and 

  
 3 








 (e) the discounted future net revenue, calculated in accordance with SEC guidelines,
attributable to reserves subject to Dollar-Denominated Production Payments that, based on the estimates of production and price assumptions included in determining the discounted future net revenue specified in clause (1)(a) above (utilizing
the prices utilized in such Person’s year end reserve report), would be necessary to satisfy fully the obligations of such Person and its Restricted Subsidiaries with respect to Dollar-Denominated Production Payments on the schedules specified
with respect thereto. 
 If Holdings changes its method of accounting from the full cost method to the successful efforts method
or a similar method of accounting, “Adjusted Consolidated Net Tangible Assets” of Holdings will continue to be calculated as if Holdings were still using the full cost method of accounting. 

“Administrative Agent” shall mean Cyan Partners, LP (or its designee, including any Person designated pursuant to
Section 10.10(f)), in its capacity as Administrative Agent for the Lenders hereunder and under the other Credit Documents, and shall include any successor to the Administrative Agent appointed pursuant to Section 10.10.

 “Affiliate” of any specified Person shall mean any other Person directly or indirectly controlling or
controlled by or under direct or indirect common control with such specified Person. For purposes of this definition, “control,” as used with respect to any Person, means the possession, directly or indirectly, of the power to direct or
cause the direction of the management or policies of such Person, whether through the ownership of voting securities, by agreement or otherwise. For purposes of this definition, the terms “controlling,” “controlled by” and
“under common control with” have correlative meanings.

meaning provided in Section 8.05.

 4

Hedging Agreement or Third Party Letter of Credit, a Person that, at the time such Hedging Agreement is entered into or such Third Party Letter of Credit is issued, as the case may be, is (a) the Administrative Agent or any Affiliate of the
Administrative Agent or (b) any other Person that is reasonably acceptable to the Administrative Agent. 
 “Asset
Sale” shall mean: 
 (1) the sale, lease, conveyance or other disposition of any properties or assets (including by way

time and from time to time on or after the Effective Date and prior to the Maturity Date, a revolving loan or revolving loans (each, a “Loan” and, collectively, the “Loans”) to the Borrower, which Loans
(i) shall be denominated in Dollars, (ii) may be repaid and reborrowed in accordance with the provisions hereof, and (iii) shall not exceed for any such Lender at any time outstanding the Available Commitment of such Lender at such
time (with such outstanding Loans to be calculated without regard to any PIK Interest that may have been added to the outstanding principal amount of Loans pursuant to Section 2.07). All references herein to a “Loan” or
“Loans”, to “principal” or the “principal amount” of any Loan or Loans and other terms of like import shall mean Loans incurred by the Borrower plus PIK Interest that is added to outstanding principal of Loans
pursuant to Section 2.07 minus repayments and prepayments of Loans pursuant to this Agreement. 
 2.02. Minimum
Amount of Each Borrowing. The aggregate principal amount of each Borrowing shall not be less than $2,500,000. 
 2.03.
Notice of Borrowing. (a) When the Borrower desires to incur Loans hereunder, the Borrower shall give the Administrative Agent at the Notice Office at least five Business Days’ prior notice thereof; provided that any such
notice shall be deemed to have been given on a certain day only if given before 11:00 A.M. (New York City time) on such day. Such notice (the “Notice of Borrowing”), shall be irrevocable and shall be in writing, or by telephone
promptly confirmed in writing, in the form of Exhibit A, appropriately completed to specify: (i) the aggregate principal amount of the Loans to be incurred pursuant to such Borrowing and (ii) the date of such Borrowing (which shall be a
Business Day). The Administrative Agent shall promptly (and in any event within one Business Day of receipt of a Notice of Borrowing) give each Lender notice of such proposed Borrowing, of such Lender’s proportionate share thereof and of the
other matters required by the immediately preceding sentence to be specified in the Notice of Borrowing. 
 (b) Without in any
way limiting the obligation of the Borrower to confirm in writing any telephonic notice of any Borrowing or prepayment of Loans, the Administrative Agent may act without liability upon the basis of telephonic notice of such Borrowing or prepayment,
as the case may be, believed by the Administrative Agent in good faith to be from an Authorized Officer of the Borrower, prior to receipt of written confirmation. In each such case, the Borrower hereby waives the right to dispute the Administrative
Agent’s record of the terms of such telephonic notice of such Borrowing or prepayment of Loans, as the case may be, absent manifest error. 
 2.04. Disbursement of Funds. No later than 1:00 P.M. (New York City time) on the date specified in each Notice of Borrowing, each Lender will make available its pro rata portion
(determined in accordance with Section 2.06) of the Borrowing requested to be made on such date. All such amounts will be made available in Dollars and in immediately available funds at the Payment Office, and the Administrative Agent
will make available to the Borrower at the Payment Office the aggregate of the amounts so made available by the Lenders. Unless the Administrative Agent shall have been notified by any Lender prior to the date of such Borrowing that such Lender does
not intend to make available to the Administrative Agent such Lender’s portion of such Borrowing to be made on such date, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such
date of Borrowing and the Administrative Agent may (but shall not be obligated to), in reliance upon such assumption, make available to the Borrower a corresponding amount. If such 

  
 47 









 
corresponding amount is not in fact made available to the Administrative Agent by such Lender, the Administrative Agent shall be entitled to recover such corresponding amount on demand from such
Lender. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent shall promptly notify the Borrower, and the Borrower shall immediately pay such corresponding
amount to the Administrative Agent. The Administrative Agent also shall be entitled to recover on demand from such Lender or the Borrower, as the case may be, interest on such corresponding amount in respect of each day from the date such
corresponding amount was made available by the Administrative Agent to the Borrower until the date such corresponding amount is recovered by the Administrative Agent, at a rate per annum equal to (i) if recovered from such Lender, the overnight
Federal Funds Rate for the first three days and at the interest rate otherwise applicable to such Loans for each day thereafter and (ii) if recovered from the Borrower, the rate of interest applicable to the Loans, as determined pursuant to
Section 2.07. Nothing in this Section 2.04 shall be deemed to relieve any Lender from its obligation to make Loans hereunder or to prejudice any rights which the Borrower may have against any Lender as a result of any failure
by such Lender to make Loans hereunder. 
 2.05. Notes. (a) The Borrower’s obligation to pay the principal of,
and interest on, the Loans made by each Lender shall be stated in the Register maintained by the Administrative Agent pursuant to Section 11.15 and shall also be stated in a promissory note duly executed and delivered by the Borrower
substantially in the form of Exhibit B, with blanks appropriately completed in conformity herewith (each, a “Note” and, collectively, the “Notes”). 

(b) Each Lender will note on its internal records the amount of Loans made by it (as well as any increase thereto as a result of the
payment of PIK Interest) and each payment in respect thereof and prior to any transfer of any of its Notes will endorse on the reverse side thereof the outstanding principal amount of Loans evidenced thereby. Failure to make any such notation or any
error in such notation shall not affect the Borrower’s obligations in respect of such Loans. 
 (c) Notwithstanding
anything to the contrary contained above in this Section 2.05, no failure of any Lender to obtain, maintain or produce a Note shall affect, or in any manner impair, the obligations of the Borrower to pay the Loans (and all related
Obligations) incurred by the Borrower which would otherwise be stated therein in accordance with the requirements of this Agreement, and shall not in any way affect the security or guaranties therefor provided pursuant to any Credit Document. Any
Lender which does not have a Note shall in no event be required to make the notations otherwise described in preceding clause (b). At any time when any Lender becomes a party to this Agreement, the Borrower shall promptly execute and deliver to the
respective Lender a Note in an amount equal to the aggregate principal amount of the Loans made or held by such Lender. 
 2.06.
Pro Rata Borrowings. All Borrowings of Loans under this Agreement shall be incurred from the Lenders pro rata on the basis of their Available Commitments. It is understood that no Lender shall be responsible for any default by
any other Lender of its obligation to make Loans hereunder and that each Lender shall be obligated to make the Loans provided to be made by it hereunder, regardless of the failure of any other Lender to make its Loans hereunder. 

  
 48 









 2.07. Interest. (a) The Borrower agrees to pay cash interest (“Cash
Interest”) in respect of the unpaid principal amount of the Loans from the date of Borrowing thereof until the maturity thereof (whether by acceleration or otherwise), at a rate per annum equal to (i) during the period from the
Effective Date until the Escrow Release Date, 12% and (ii) from and after the Escrow Release Date, 13%. 
 (b) In addition
to the payment of Cash Interest pursuant to preceding clause (a), the Borrower shall, during the period from the Effective Date until the Escrow Release Date, pay additional interest on the Loans at a rate per annum equal to 3.0% “in
kind”, with the amount of interest accruing pursuant to this clause (b) being added to the outstanding principal amount of the Loans on each Quarterly Payment Date occurring during such period; provided that in the event the
Borrower provides written notice thereof to the Administrative Agent prior to 11:00 A.M. (New York City time) at least two Business Days prior to the relevant Quarterly Payment Date, the Borrower may pay in cash interest accrued pursuant to this
clause (b) that is payable on such Quarterly Payment Date. Such paid-in-kind interest (“PIK Interest”) shall be deemed paid, and the principal amount of the Loans as so increased shall be deemed “Loans” hereunder and
under the other Credit Documents for all purposes and shall thereafter accrue interest in accordance with the terms of this Agreement. 
 (c) Overdue principal and, to the extent permitted by law, overdue interest in respect of each Loan and all other overdue amounts payable hereunder and under any other Credit Document shall bear interest
at a rate per annum equal to the rate which is 2% in excess of the rate then borne by the Loans. Interest that accrues under this Section 2.07(b) shall be payable on demand. 

(d) Accrued (and theretofore unpaid) interest on Loans shall be payable (i) quarterly in arrears on each Quarterly Payment Date,
(ii) on the date of any repayment or prepayment (on the amount repaid or prepaid) and (iii) at maturity (whether by acceleration or otherwise) and, after such maturity, on demand. 

2.08. Change of Lending Office. Each Lender agrees that on the occurrence of any event giving rise to the operation of
Section 2.10 or 4.04 with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected
by such event; provided that such designation is made on such terms that such Lender and its lending office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the
operation of such Section. Nothing in this Section 2.08 shall affect or postpone any of the obligations of the Borrower or the right of any Lender provided in Section 2.10 or 4.04. 

2.09. Replacement of Lenders. (a) If any Lender becomes a Defaulting Lender, (b) upon the occurrence of any event giving
rise to the operation of Section 2.10 or 4.04 with respect to any Lender which results in such Lender charging to the Borrower increased costs in excess of those being generally charged by the other Lenders or (c) in the case of a refusal
by a Lender to consent to a proposed change, waiver, discharge or termination with respect to this Agreement which has been approved by the Required Lenders as (and to the extent) provided in Section 11.12(b), the Borrower shall have the right,
subject to Section 11.12(c), in accordance

with Section 11.04(b), if no Default or Event of Default then exists or would exist after giving effect to such replacement, to replace such Lender (the “Replaced
Lender”) with one or more other Eligible Transferees, none of whom shall constitute a Defaulting Lender at the time of such replacement (collectively, the “Replacement Lender”) and each of which shall be reasonably
acceptable to the Administrative Agent; provided that:

the Borrower) pursuant to which the Replacement Lender shall acquire all of the Commitments (if any) and outstanding Loans of the Replaced Lender and, in connection therewith, shall pay to the Replaced Lender in respect thereof an amount equal to
the sum of (x) an amount equal to the principal of, and all accrued and unpaid interest on, all outstanding Loans of the respective Replaced Lender, and (y) an amount equal to all accrued, but theretofore unpaid, Fees owing to the Replaced
Lender pursuant to Section 3.01; and 
 (B) all obligations of the Borrower then owing to the
Replaced Lender (other than those specifically described in clause (A) above in respect of which the assignment purchase price has been, or is concurrently being, paid) shall be paid in full to such Replaced Lender concurrently with such
replacement. 
 Upon receipt by the Replaced Lender of all amounts required to be paid to it pursuant to this Section 2.09, the
Administrative Agent shall be entitled (but not obligated) and authorized to execute an Assignment and Assumption Agreement on behalf of such Replaced Lender, and any such Assignment and Assumption Agreement so executed by the Administrative Agent
and the Replacement Lender shall be effective for purposes of this Section 2.09 and Section 11.04. Upon the execution of the respective Assignment and Assumption Agreement, the payment of amounts referred to in clauses
(A) and (B) above, recordation of the assignment on the Register by the Administrative Agent pursuant to Section 11.15 and delivery to the Replacement Lender of the appropriate Note or Notes executed by the Borrower, the
Replacement Lender shall become a Lender hereunder and the Replaced Lender shall cease to constitute a Lender hereunder, except with respect to indemnification provisions under this Agreement (including, without limitation, Sections 2.10,
4.04, 10.06, 11.01 and 11.06), which shall survive as to such Replaced Lender. 
 2.10. Capital Adequacy.
(a) If any Lender determines that after the Effective Date the introduction of or any change in any applicable law or governmental rule, regulation, order, guideline, directive or request (whether or not having the force of law) concerning
capital adequacy, or any change in interpretation or administration thereof by the NAIC or any Governmental Authority, central bank or comparable agency, will have the effect of increasing the amount of capital required or expected to be maintained
by such Lender or any corporation controlling such Lender based on the existence of such Lender’s Commitment hereunder or its obligations hereunder, then the Borrower agrees to pay to such Lender, upon its written demand therefor, such
additional amounts as shall be required to compensate such Lender or such other corporation for the increased cost to such Lender or such other corporation or the reduction in the rate of return to such Lender or such other corporation as a result
of such increase of capital. In 

  
 50 









 
determining such additional amounts, each Lender will act reasonably and in good faith and will use averaging and attribution methods which are reasonable; provided that such Lender’s
determination of compensation owing under this Section 2.10 shall, absent manifest error, be final and conclusive and binding on all the parties hereto. Each Lender, upon determining that any additional amounts will be payable pursuant
to this Section 2.10, will give prompt written notice thereof to the Borrower, which notice shall show in reasonable detail the basis for calculation of such additional amounts. 

(b) Notwithstanding anything in this Agreement to the contrary, (x) the Dodd-Frank Wall Street Reform and Consumer Protection Act
and all requests, rules, guidelines, requirements and directives thereunder, issued in connection therewith or in implementation thereof and (y) all requests, rules, guidelines or directives promulgated by the Bank for International
Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III shall in each case be deemed to be a change after the
Effective Date in a requirement of law or government rule, regulation or order, regardless of the date enacted, adopted, issued or implemented (including for purposes of this Section 2.10). 

2.11. Incremental Revolving Loans. (a) The Borrower may at any time or from time to time after the Syndication Date (or
earlier if approved by the Administrative Agent), by notice to the Administrative Agent (whereupon the Administrative Agent shall promptly deliver a copy to each of the Lenders), request one or more increases in the amount of the Commitments, each
such increase, a “Commitment Increase”; provided that (i) both at the time of any such request and upon the effectiveness of any Incremental Amendment referred to below, no Default or Event of Default shall exist,
(ii) unless otherwise agreed to by the Required Lenders, the Total Commitments shall not exceed $100,000,000 after giving effect to any Commitment Increases, (iii) unless agreed to by the Supermajority Lenders, the Total Commitments shall
not exceed $150,000,000 after giving effect to any Commitment Increases and (iv)(1) the aggregate amount of any Commitment Increase pursuant to this Section 2.11 shall not exceed such amount as is equal to the difference of
(x) the amount of Indebtedness which is then permitted to be incurred by the Borrower and the other Credit Parties in reliance on Section 4.09(1)(a), (1)(b) or (1)(c) (as applicable) of the Indentures minus (y) the
Total Commitments outstanding hereunder immediately prior to such Commitment Increase and (2) the Borrower shall have delivered to the Administrative Agent an Officer’s Certificate certifying, in reasonable detail, as to compliance with
the requirements of preceding subclause (iv)(1). Each Commitment Increase shall be in an aggregate principal amount that is not less than $2,500,000. Loans made pursuant to any Commitment Increase shall have the same terms and conditions as
those applicable to the Loans. Each notice from the Borrower pursuant to this Section 2.11 shall set forth the requested amount of the relevant Commitment Increases. Commitment Increases may be made by any existing Lender (but no
existing Lender will have any obligation to make a portion of any Commitment Increase) or by any other bank or other financial institution that is an Eligible Transferee (any such other bank or other financial institution being called an
“Additional Lender”); provided that the Administrative Agent shall have consented (not to be unreasonably withheld, conditioned or delayed) to such Additional Lender’s providing any such Commitment Increase. Commitment
Increases shall be provided pursuant to an amendment (an “Incremental Amendment”) to this Agreement and, as appropriate, the other Credit Documents, executed by Holdings, the Borrower, each Lender agreeing to provide such Commitment
Increases, if any, each Additional Lender, if any, and the Administrative Agent. The Incremental Amendment may, with the 

  
 51 









 
consent of Holdings, the Borrower and the Administrative Agent, but without the consent of any other Credit Party, the Collateral Agent or Lenders, effect such amendments to this Agreement and
the other Credit Documents as may be necessary or appropriate, in the reasonable opinion of the Administrative Agent and the Borrower, to effect the provisions of this Section 2.11. The Borrower may use the proceeds of the Loans made
pursuant to any Commitment Increase for any purpose not prohibited by this Agreement. 
 (b) If, on the date of any increase in
the Commitments pursuant to this Section, there are any Loans outstanding, such Loans shall on or prior to the effectiveness of such Commitment Increase be prepaid from the proceeds of additional Loans made hereunder (reflecting such increase in
Commitments), which prepayment shall be accompanied by accrued interest on the Loans being prepaid and any costs incurred by any Lender in accordance with Section 2.10. The Administrative Agent and the Lenders hereby agree that the
minimum borrowing, pro rata borrowing and pro rata payment requirements contained elsewhere in this Agreement shall not apply to the transactions effected pursuant to the immediately preceding sentence. 

SECTION 3. Fees; Reductions of Commitment. 
 3.01. Fees. (a) The Borrower agrees to pay to the Administrative Agent for distribution to each Non-Defaulting Lender a commitment commission (the “Commitment Commission”) for
the period from and including the Effective Date to and including the Maturity Date (or such earlier date on which the Total Commitment has been terminated) computed at a rate per annum equal to 5.0% of the Unutilized Commitment of such
Non-Defaulting Lender as in effect from time to time. Accrued Commitment Commission shall be due and payable to each Lender (based on its pro rata share thereof) quarterly in arrears on each Quarterly Payment Date and on the date upon which the
Total Commitment is terminated. 
 (b) Voluntary termination of Commitments pursuant to Section 3.02 prior to the date
which is three months after the Effective Date, will be subject to payment to the Administrative Agent, for the ratable account of each Lender, of a fee equal to the amount of interest and Commitment Commission that would have accrued from the date
of such termination through and including the date which is three months after the Effective Date, assuming such termination had not occurred (in each case, with the calculation of such amount based on the average principal amount of Loans
outstanding from the Effective Date through to the date of such termination). Any voluntary reduction of Commitments pursuant to Section 3.02, shall be subject to a fee calculated in the same manner as provided for the fee payable pursuant to
the preceding sentence but reduced on a ratable basis by reference to the proportion that the amount of such Commitment reduction bears to the Total Commitment as in effect at such time. Such fees shall be due and payable upon the date of any
voluntary prepayment or the due date of such required repayment, as the case may be. 
 (c) The Borrower agrees to pay to the
Administrative Agent such fees as may be agreed to in writing from time to time by Holdings, the Borrower or any of its Subsidiaries and the Administrative Agent. 

  
 52 









 3.02. Voluntary Termination or Reduction of Unutilized Commitments. Upon at least
three Business Days’ prior written notice to the Administrative Agent at the Notice Office (which notice the Administrative Agent shall promptly transmit to each of the Lenders), the Borrower shall have the right, at any time or from time to
time, without premium or penalty (except as provided in Section 3.01(b)) to terminate the Total Unutilized Commitment in whole, or reduce it in part, pursuant to this Section 3.02, in an integral multiple of $5,000,000 in the
case of partial reductions to the Total Unutilized Commitment; provided that each such reduction shall apply proportionately to permanently reduce the Commitment of each Lender. 

3.03. Mandatory Termination of Commitments. (a) The Total Commitment (and the Commitment of each Lender) shall terminate in
its entirety on the Maturity Date. 
 (b) The Commitments of the Lenders shall be reduced as and when required in accordance with
Section 8.04. 
 SECTION 4. Prepayments; Payments; Taxes. 

4.01. Voluntary Prepayments. The Borrower shall have the right to prepay the Loans, without premium or penalty, in whole or in part
at any time and from time to time on the following terms and conditions: (i) the Borrower shall give the Administrative Agent prior to 12:00 Noon (New York City time) at the Notice Office at least three Business Days’ prior written notice
(or telephonic notice promptly confirmed in writing) of its intent to prepay Loans, which notice shall specify the amount of such prepayment and which notice the Administrative Agent shall, promptly transmit to each of the Lenders; (ii) each
partial prepayment of Loans pursuant to this Section 4.01 shall be in an aggregate principal amount of at least $1,000,000 (or such lesser amount as is acceptable to the Administrative Agent); and (iii) each prepayment of Loans
pursuant to this Section 4.01 shall be applied pro rata among such Loans. 
 4.02. Mandatory
Repayments. 
 (a) On any day on which the aggregate outstanding principal amount of all Loans (with such outstanding Loans
to be calculated without regard to any PIK Interest that may have been added to the outstanding principal amount of Loans pursuant to Section 2.07, but after giving effect to all other repayments thereof on such date) exceeds the Total
Available Commitment at such time, the Borrower shall repay on such day Loans in an amount equal to such excess. 
 (b) In
addition to any other mandatory prepayments required pursuant to this Section 4.02, all then outstanding Loans shall be repaid in full on the Maturity Date. 
 4.03. Method and Place of Payment. All payments of principal and Cash Interest under this Agreement and under any Note shall be made to the Administrative Agent for the account of the Lender or
Lenders entitled thereto not later than 12:00 Noon (New York City time) on the date when due and shall be made in Dollars in immediately available funds at the Payment Office. Whenever any payment to be made hereunder or under any Note shall be
stated to be due on a day which is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day and, with respect to payments of principal, interest shall be payable at the applicable rate during such extension.


  
 53 









 4.04. Tax Gross-Up and Indemnities. 

(a) Tax gross-up. 
 (i) Each Credit Party shall make all payments to be made by it without any Tax Deduction, unless a Tax Deduction is required by law. 

(ii) The Borrower shall promptly upon becoming aware that a Credit Party must make a Tax Deduction (or that there is any change in the
rate or the basis of a Tax Deduction) notify the Administrative Agent accordingly. 
 (iii) If a Tax Deduction is required by
law to be made by a Credit Party, the amount of the payment due from that Credit Party shall be increased to an amount which (after making any Tax Deduction) leaves an amount equal to the payment which would have been due if no Tax Deduction had
been required. 
 (iv) If a Credit Party is required to make a Tax Deduction, that Credit Party shall make that Tax Deduction
and any payment required in connection with that Tax Deduction within the time allowed and in the amount required by law. 
 (v)
Within thirty days of making either a Tax Deduction or any payment required in connection with that Tax Deduction, the Credit Party making that Tax Deduction shall deliver to the Administrative Agent for the Lender entitled to the payment a
statement under section 975 of the UK’s Income Tax Act 2007, or other applicable law, reasonably satisfactory to that Lender that the Tax Deduction has been made or (as applicable) any appropriate payment has been paid to the relevant taxing
authority. 
 (vi) A Treaty Lender (to the extent it is legally entitled to), and each Credit Party which makes a payment to
which that Treaty Lender is entitled, shall use reasonable efforts to co-operate in completing any procedural formalities necessary for that Credit Party to obtain authorization to make that payment without a Tax Deduction. However, notwithstanding
the foregoing, a Treaty Lender shall not be required to disclose any information regarding its owners. 
 (vii) Any Lender, if
requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to
determine whether or not such Lender is subject to United States backup withholding or information reporting requirements. 

(b) Tax indemnity. 
 (i) The Borrower shall (within ten Business Days of demand by the Administrative Agent) pay to a Protected Party an amount equal to the loss, liability or cost which that Protected Party determines will
be or has been suffered for or on account of Tax by that Protected Party in respect of a Credit Document. 
 (ii) Paragraph
(i) above shall not apply: 

  
 54 









 (A) with respect to any Tax assessed on a Lender or Agent: 

(1) under the law of the jurisdiction in which that Lender or Agent is incorporated or, if different, the jurisdiction (or
jurisdictions) in which that Lender or Agent is treated as resident for tax purposes; or 
 (2) under the law of
the jurisdiction in which that Lender’s lending office is located in respect of amounts received or receivable in that jurisdiction, 
 if that Tax is imposed on or calculated by reference to the net income received or receivable (but not any sum deemed to be received or receivable) by that Agent or Lender; or 

(B) to the extent a loss, liability or cost has been compensated for by an increased payment under
Section 4.04(a). 
 (iii) A Protected Party making, or intending to make a claim under paragraph (a) above
shall promptly notify the Administrative Agent of the event which will give, or has given, rise to the claim, following which the Administrative Agent shall notify the Borrower. 

(iv) A Protected Party shall, on receiving a payment from a Credit Party under this Section 4.04(b), notify the
Administrative Agent. 
 (c) Tax Refund. If a Credit Party makes a Tax Payment and the relevant Lender or Agent
determines that: 
 (i) a Tax Refund is attributable either to an increased payment of which that Tax Payment forms part, or to
that Tax Payment; and 
 (ii) that Lender or Agent has obtained, utilized and retained that Tax Refund, 

the Lender or Agent shall pay an amount to the Credit Party which that Lender or Agent reasonably determines will leave it (after that payment) in the
same after-Tax position as it would have been in had the Tax Payment not been required to be made by the Credit Party. Notwithstanding any provision in this Agreement or any other Credit Document, nothing in this Section 4.04 shall
require a Lender or the Administrative Agent to disclose any confidential information to any Credit Party (including, without limitation, its tax returns or its calculations). 
 (d) Stamp Taxes. The Borrower shall pay and, within three Business Days of demand, indemnify each Lender and each Agent against any cost, loss or liability that Lender or any Agent incurs in
relation to all stamp duty, registration and other similar Taxes payable in respect of any Credit Document. 
 (e) VAT.


  
 55 









 (i) All amounts set out, or expressed in a Credit Document to be payable by any Credit Party
to a Lender or Agent which (in whole or in part) constitute the consideration for a supply or supplies for VAT purposes shall be deemed to be exclusive of any VAT which is chargeable on such supply or supplies, and accordingly, subject to paragraph
(ii) below, if VAT is or becomes chargeable on any supply made by any Lender or Agent to any Credit Party under a Credit Document, that Credit Party shall pay to the Lender or Agent (in addition to and at the same time as paying any other
consideration for such supply) an amount equal to the amount of such VAT (and such Lender or Agent shall promptly provide an appropriate VAT invoice to such Credit Party). 
 (ii) If VAT is or becomes chargeable on any supply made by any Lender or Agent (the “Supplier”) to any other Lender or Agent (the “Recipient”) under a Credit Document,
and any Credit Party other than the Recipient (the “Subject Party”) is required by the terms of any Credit Document to pay an amount equal to the consideration for such supply to the Supplier (rather than being required to reimburse
the Recipient in respect of that consideration), such Credit Party shall also pay to the Supplier (in addition to and at the same time as paying such amount) an amount equal to the amount of such VAT. The Recipient will promptly pay to the Subject
Party an amount equal to any credit or repayment obtained by the Recipient from the relevant tax authority which the Recipient reasonably determines in respect of such VAT. 
 (iii) Where a Credit Document requires any Credit Party to reimburse or indemnify a Lender or Agent for any cost or expense, the Credit Party shall reimburse or indemnify (as the case may be) such Lender
or Agent for the full amount of such cost or expense, including such part thereof as represents VAT, save to the extent that such Lender or Agent reasonably determines that it is entitled to credit or repayment in respect of such VAT from the
relevant tax authority. 
 (iv) Any reference in this Section 4.04(e) to any Credit Party shall, at any time when
such Credit Party is treated as a member of a group for VAT purposes, include (where appropriate and unless the context otherwise requires) a reference to the representative member of such group at such time (the term “representative
member” to have the same meaning as in the Value Added Tax Act 1994). 
 (f) For the purposes of this
Section 4.04, any reference to a U.K. statutory provision includes a reference to that provision as modified or replaced from time to time after the Effective Date.

 (b) On and as of the Effective Date, and after giving effect to those of the Transactions to
be consummated on the Effective Date and to all Indebtedness being incurred or assumed and Loans incurred by the Credit Parties in connection therewith on such date, (i) the sum of the fair value of the assets, at a fair valuation, of the
Credit Parties and their Subsidiaries (taken as a whole) will exceed their debts (taken as a whole), (ii) the sum of the present fair salable value of the assets of the Credit Parties and their Subsidiaries (taken as a whole) will exceed their
debts (taken as a whole), (iii) the Credit Parties and their Subsidiaries (taken as a whole) have not incurred and do not intend to incur, and do not believe that they will incur, debts beyond their ability to pay such debts as such debts
mature, and (iv) the Credit Parties and their Subsidiaries (taken as a whole) will have sufficient capital with which to conduct their businesses. For purposes of this Section 6.05(b), “debt” means any liability on a
claim, and “claim” means (A) right to payment, whether or not such a right is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed, legal, equitable, secured, or unsecured or
(B) right to an equitable remedy for breach of performance if such breach gives rise to a payment, whether or not such right to an equitable remedy is reduced to judgment, fixed, contingent, matured, unmatured, disputed, undisputed, secured or
unsecured. The amount of contingent liabilities at any time shall be computed as the amount that, in the light of all the facts and circumstances existing at such time, represents the amount that can reasonably be expected to become an actual or
matured liability. 
 (c) Except as disclosed in the financial statements delivered pursuant to this
Section 6.05(a), and except for the Indebtedness incurred and/or outstanding under this Agreement, there were as of the Effective Date no liabilities or obligations with respect to Holdings or any of its Subsidiaries of any nature
whatsoever (whether absolute, accrued, contingent or otherwise and whether or not due) which, either individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect. As of the Effective Date, neither Holdings nor the
Borrower knows of any basis for the assertion against it or any of its Subsidiaries of any liability or obligation of any nature whatsoever that is not disclosed in such financial statements delivered pursuant to this Section 6.05(a) or
referred to in the immediately preceding sentence which, either individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect. 
 (d) After giving effect to the Transactions, since December 31, 2011, nothing has occurred that has had, or could reasonably be expected to have, either individually or in the aggregate, a Material
Adverse Effect.

 6.07. True and Complete Disclosure. All factual information (taken as a whole)
furnished by or on behalf of Holdings or the Borrower to the Administrative Agent or any 
 Lender (including, without limitation, all
information contained in the Credit Documents) for purposes of or in connection with this Agreement, the other Credit Documents or any transaction contemplated herein or therein is, and all other such factual information (taken as a whole) hereafter
furnished by or on behalf of Holdings or the Borrower in writing to the Administrative Agent or any Lender will be, true and accurate in all material respects on the date as of which such information is dated or certified and not incomplete by
omitting to state any fact necessary to make such information (taken as a whole) not misleading in any material respect at such time in light of the circumstances under which such information was provided. 

6.08. Use of Proceeds; Margin Regulations. (a) All proceeds of the Loans shall be used (i) to fund expansionary Capital

 (b) No part of the proceeds of any Loan will be used to purchase or carry any Margin Stock or to extend credit for the purpose of purchasing or carrying any Margin Stock. Neither the making of any Loan
nor the use of the proceeds thereof will violate or be inconsistent with the provisions of Regulation T, U or X. 
 6.09. Tax
Returns and Payments. Each of Holdings and each of its Subsidiaries has timely filed or caused to be timely filed with the appropriate taxing authority all Federal,, foreign, state and material local returns, statements, forms and reports for
taxes (the “Returns”) required to be filed by, or with respect to the income, properties or operations of, Holdings and/or any of its Subsidiaries. The Returns accurately reflect in all material respects all liability for taxes of Holdings
and its Subsidiaries, as applicable, for the periods covered thereby. Each of Holdings and each of its Subsidiaries has paid all taxes and assessments payable by it which have become due, other than (a) those that are being contested in good
faith and adequately disclosed and for which adequate reserves have been established in accordance with GAAP and (b) immaterial amounts of taxes or assessments that Holdings and its Subsidiaries are not aware are due; provided that upon
Holdings or such Subsidiary becoming aware that such taxes and assessments are due, such Person shall promptly pay all such taxes and assessments, together with any interest and additional charges thereon. There is no action, suit, proceeding,
investigation, audit or claim now pending or, to the knowledge of Holdings or the Borrower, threatened (in writing) by any authority regarding any taxes relating to Holdings or any of its Subsidiaries. As of the Effective Date, neither Holdings nor
any of its Subsidiaries has entered into an agreement or waiver or been requested to enter into an agreement or waiver extending any statute of limitations relating to the payment or collection of taxes of Holdings or any of its Subsidiaries, or is
aware of any circumstances that would cause the taxable years or other taxable periods of Holdings or any of its Subsidiaries not to be subject to the normally applicable statute of limitations. Neither Holdings nor any of its Subsidiaries has
incurred, nor will any of them incur, any material tax liability in connection with the Transactions or any other transactions contemplated hereby (it being understood that the representation contained in this sentence does not cover any future tax
liabilities of Holdings or any of its Subsidiaries arising as a result of the operation of their businesses in the ordinary course of business) or any tax liability resulting from indemnification (or yield protection provisions) under this
Agreement).

Pension Schemes Act 1993) or “connected” with or an “associate” of (as those terms are used in sections 38 or 43 of the United Kingdom’s Pensions Act 2004) such an employer. 

7.08. End of Fiscal Years; Fiscal Quarters. Holdings will cause (a) its and each of its Subsidiaries’ fiscal years to
end on December 31 of each calendar year and (b) its and each of its Subsidiaries’ fiscal quarters to end on March 31, June 30, September 30 and December 31; provided that nothing in this
Section 7.08 shall prohibit any Subsidiary of Holdings from maintaining a tax year that does not end on December 31. 
 7.09. Performance of Obligations. Holdings will, and will cause each of its Subsidiaries to, perform all of its obligations under the terms of each mortgage, indenture, security agreement, loan
agreement or credit agreement and each other agreement, contract or instrument by which it is bound, except such non-performances as could not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.


  
 80 









 7.10. Payment of Taxes. Holdings will pay and discharge, and will cause each of its
Subsidiaries to pay and discharge, all taxes, assessments and governmental charges or levies imposed upon it or upon its income or profits or upon any properties belonging to it, prior to the date on which penalties attach thereto, and all lawful
claims which, if unpaid, would become a Lien or charge upon any properties of Holdings or any of its Subsidiaries not otherwise permitted under Section 8.06 or Section 8.01 of the Existing Credit Agreement, as applicable;
provided that neither Holdings nor any of its Subsidiaries shall be required to pay any such tax, assessment, charge, levy or claim which is being contested in good faith and by proper proceedings if it has maintained adequate reserves with
respect thereto in accordance with GAAP. 
 7.11. Use of Proceeds. The Borrower will use the proceeds of the Loans only
as provided in Section 6.08. 
 7.12. Additional Security; Further Assurances; etc. (a) Holdings will, and
will cause each other Credit Party to, grant to the Collateral Agent for the benefit of the Secured Creditors security interests in such assets of Holdings and such other Credit Party (including, without limitation properties of Holdings and such
other Credit Party acquired subsequent to the Effective Date) as are not covered by the original Security Documents (including, without limitation, with respect to any such property, pursuant to grants pursuant to the laws of Scotland) and as may be
reasonably requested from time to time by the Administrative Agent or the Required Lenders (collectively, the “Additional Security Documents”); provided that no Credit Party shall be required to take any action to grant or
perfect a security interest on any Excluded Asset. All such security interests shall be granted pursuant to documentation satisfactory in form and substance to the Collateral Agent and shall constitute valid and enforceable perfected security
interests and hypothecations superior to and prior to the rights of all third Persons and enforceable against third parties and subject to no other Liens except for Permitted Liens. The Additional Security Documents or instruments related thereto
shall have been duly recorded or filed in such manner and in such places as are required by law to establish, perfect, preserve and protect the Liens in favor of the Collateral Agent required to be granted pursuant to the Additional Security
Documents and all taxes, fees and other charges payable in connection therewith shall have been paid in full. 
 (b) Holdings
will, and will cause each of the other Credit Parties to, at the expense of Holdings and the Borrower, make, execute, endorse, acknowledge, file and/or deliver to the Collateral Agent from time to time such vouchers, invoices, schedules,
confirmatory assignments, conveyances, financing statements, transfer endorsements, powers of attorney, certificates, real property surveys, reports, landlord lien waivers, collateral access agreements, bailee agreements, control agreements and
other assurances or instruments and take such further steps relating to the Collateral covered by any of the Security Documents as the Collateral Agent may reasonably require. Furthermore, Holdings will, and will cause the other Credit Parties to,
deliver to the Collateral Agent such opinions of counsel, title insurance and other related documents as may be reasonably requested by the Collateral Agent to assure itself that this Section 7.12 has been complied with. 

(c) Holdings will cause (i) each Subsidiary (other than any Immaterial Subsidiary or Unrestricted Subsidiary) that is established,
created or acquired after the Effective Date and (ii) each Non-Guarantor Subsidiary (other than an Unrestricted Subsidiary) that ceases to be an Immaterial Subsidiary, in each case, to become a Guarantor and a party (in such capacity, a
“Grantor”) to the U.S. Security Agreement, the English Security Documents and/or 

  
 81 









 
such other Security Documents as may be required by the Collateral Agent such that the Collateral Agent, for the benefit of the Secured Creditors, has a first priority security interest (or if
prior to the Escrow Release Date, a second-priority security interest) in all assets (other than Excluded Assets) of such Subsidiary or Non-Guarantor Subsidiary (as applicable). In addition, if, after the date hereof, any Restricted Subsidiary of
Holdings that is not already a Guarantor and a Grantor guarantees any other Indebtedness of Holdings or any Guarantor in excess of the De Minimum Guaranteed Amount, then that Subsidiary shall become a Guarantor and a Grantor. Any such Subsidiary
shall become a Guarantor and a Grantor pursuant to this clause (c) by executing joinders to the Subsidiaries Guaranty and the applicable Security Documents in form and substance satisfactory to the Administrative Agent whereby such Subsidiary
shall guaranty the Obligations and grant a security interest to the Collateral Agent, for the benefit of the Secured Creditors, in the assets (other than Excluded Assets) of such Subsidiary and, in each case, delivering such documents to the
Administrative Agent within 60 days of the date on which it was established, created or acquired or ceased to be an Immaterial Subsidiary, as applicable (or such later date as may be agreed by the Administrative Agent in its sole discretion), or
within 15 days of the date on which it guaranteed such other Indebtedness (or such later date as may be agreed by the Administrative Agent in its sole discretion), as the case may be, together with any Officer’s Certificate and opinion which
may be reasonably requested by the Administrative Agent. In connection with the execution of such Security Documents, such Subsidiary shall take or cause to be taken such other actions (including delivering properly completed Uniform Commercial Code
financing statements) as may be necessary or advisable in the opinion of the Collateral Agent to vest in the Collateral Agent, for the benefit of the Secured Creditors, a first-priority perfected security interest (or if prior to the Escrow Release
Date, a second-priority perfected security interest) in such assets and to have such assets added to the Collateral and thereupon all provisions of this Agreement and the Security Documents relating to the Collateral shall be deemed to relate to
such assets to the same extent and with the same force and effect. The requirements set forth above in this clause (c) are collectively referred to herein as the “Additional Guarantor Requirement”. 

(d) Each of Holdings and the Borrower agree that each action required by clauses (a) through (c) of this
Section 7.12 shall be completed as soon as possible, but in no event later than 60 days after such action is requested to be taken by the Administrative Agent or the Required Lenders or such later date as may be otherwise provided in
such clauses; provided that, in no event will Holdings or any of its Subsidiaries be required to take any action, other than using its commercially reasonable efforts, to obtain consents from third parties with respect to its compliance with
this Section 7.12. 
 7.13. Maintenance of Company Separateness. Holdings will, and will cause each of its
Subsidiaries to, satisfy customary Business formalities, including the holding of regular Board of Directors’ and members’ meetings or action by managers or members without a meeting and the maintenance of Business records. Neither
Holdings nor any other Credit Party shall make any payment to a creditor of any Non-Guarantor Subsidiary in respect of any liability of any Non-Guarantor Subsidiary (other than (x) pursuant to Holdings’ guaranty of Endeavour Energy
Luxembourg S.a.r.l.’s obligations under the 11.5% Convertible Bonds and (y) any guaranty by Holdings or such other Credit Party of intercompany Indebtedness of any such Non-Guarantor Subsidiary owing to Holdings or any of its
Subsidiaries), and no bank account of any Non Guarantor Subsidiary shall be commingled with any bank account of Holdings or any other 

  
 82 









 
Credit Party. Any financial statements distributed to any creditors of any Non-Guarantor Subsidiary shall clearly establish or indicate the corporate separateness of such Non-Guarantor Subsidiary
from Holdings and its other Subsidiaries. Finally, neither Holdings nor any of its Subsidiaries shall take any action, or conduct its affairs in a manner, which is likely to result in the Business existence of Holdings, any other Credit Party or any
Non-Guarantor Subsidiaries being ignored, or in the assets and liabilities of Holdings or any other Credit Party being substantively consolidated with those of any other such Person or any Non-Guarantor Subsidiary in a bankruptcy, reorganization or
other insolvency proceeding. 
 7.14. Project Documents, etc. Each Credit Party shall (i) ensure that none of its
rights under or in respect of any Project Document are at any time cancelled, terminated, suspended or limited if the same would be reasonably likely to result in a Material Adverse Effect, (ii) not agree to any waiver, amendment, termination
or cancellation of any Project Document if the same would be reasonably likely to result in Material Adverse Effect, (iii) duly and properly perform, in all material respects, its obligations under the Project Documents (except to the extent,
if any, that such performance is inconsistent with its obligation under the Credit Documents or any such failure to perform as could not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect),
(iv) exercise its rights, under and in respect of the Project Documents consistently with its obligations under the Credit Documents and (v) not enter into any Project Document which would be reasonably likely to result in a Material
Adverse Effect. 
 7.15. Oil and Gas Properties. Each Credit Party shall (i) exercise such votes and other rights as
it may have under the Project Documents with a view to ensuring (so far as able) that each Oil and Gas Property in which Holding or any of its Subsidiaries has an interest is at all times exploited and operated in a reasonable and prudent manner and
in accordance with good industry practice, all applicable laws and regulations and the provisions of the Project Documents, (ii) not concur in, and shall vote against, any proposal or decision to abandon all or any material part of any of Oil
and Gas Properties in which Holdings or any of its Subsidiaries has an interest unless the Administrative Agent has granted its prior written consent, (iii) not exercise its rights on any operating or similar committee in a manner that would be
materially prejudicial to the interests of any Credit Party, the Administrative Agent or the Lenders and (iv) maintain full and proper technical and financial records in relation to each Oil and Gas Property in which Holdings or any of its
Subsidiaries has an interest and ensure (so far as it is able) that the Administrative Agent (and/or any Person nominated by it) is afforded reasonable access to each Oil and Gas Property in which it has an interest and all such records during
normal business hours on reasonable notice. 
 7.16. Listing of the Notes. (a) The Borrower shall (i) cause the
Notes (including any Notes issued in connection with the payment of PIK Interest) to be admitted for listing on either the Cayman Island Stock Exchange or Channel Island Stock Exchange (either such Exchange, an “Approved Stock
Exchange”) prior to September 28, 2012, in either case in accordance with the listing rules promulgated by the respective Approved Stock Exchange and applicable law, (ii) cause the Notes to continue to be listed on an Approved
Stock Exchange at all times from and after September 28, 2012 and (iii) comply with all obligations required pursuant to the respective Approved Stock Exchange relating to the continued listing of the Notes on such Approved Stock Exchange.


  
 83 









 (b) Promptly following receipt thereof by the Borrower, the Borrower shall deliver to the
Administrative Agent copies of all financial information, reports, documents or other materials filed with an Approved Stock Exchange. 
 7.17. Credit Facilities Baskets in Indentures. Holdings will, and will cause each of its Restricted Subsidiaries to, (i) at all times prior to the date on which the Total Commitment exceeds
$100,000,000, justify the incurrence of Loans and related Obligations under Section 4.09(1)(a)(i), (1)(b)(i) or (1)(c)(i) of each of the Indentures and (ii) at all times thereafter, justify the incurrence of
Loans and related Obligations under Section 4.09(1) of each of the Indentures. 
 7.18. Post-Closing
Obligations. 
 (a) On or prior to the Escrow Release Date, Holdings and the Borrower will deliver (or cause the applicable
Credit Party to deliver) to the Administrative Agent control agreements duly executed by each applicable Credit Party, the applicable bank and the Collateral Agent with respect to each deposit or similar account of each Credit Party set forth on
Schedule 7.18, such control agreements to be in form and substance reasonably satisfactory to the Collateral Agent. 
 (b) On or
prior to April 16, 2012, Holdings will deliver to the Administrative Agent an opinion from Woodburn and Wedge, special Nevada counsel to Holdings, addressed to the Administrative Agent, the Collateral Agent and each of the Lenders and dated the
Effective Date covering the matters set forth in Exhibit C-2 and such other matters incident to the transactions contemplated herein as the Administrative Agent may reasonably request. 

7.19. Equity Issuance. 

In the event that the Escrow Release Date has not occurred on or prior to June 1, 2012, Holdings shall take both (i) all actions necessary and
(ii) all actions requested by the Administrative Agent in order to issue common Equity Interests on or prior to June 13, 2012 in an amount sufficient to generate net cash proceeds in an amount sufficient to repay all outstanding Loans,
accrued and unpaid interest, Fees and other Obligations then outstanding. 
 SECTION 8. Negative Covenants. Each of
Holdings and the Borrower covenants and agrees that, from and after the Escrow Release Date: 
 8.01. Limitation on Restricted
Payments. Holdings will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly: 
 (1) declare or pay any dividend or make any other payment or distribution on account of Holdings’ or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any
payment in connection with any merger or consolidation involving Holdings or any of its Restricted Subsidiaries) or to the direct or indirect holders of Holdings’ or any of its Restricted Subsidiaries’ Equity Interests in their capacity as
such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of Holdings or payable to Holdings or, subject to compliance with Additional Guarantor Requirement at the time of such dividend, payment or
distribution, a Restricted Subsidiary of Holdings); 

  
 84 









 (2) purchase, redeem or otherwise acquire or retire for value (including,
without limitation, in connection with any merger or consolidation involving Holdings) any Equity Interests of Holdings or any direct or indirect parent of Holdings; 

(3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any
Indebtedness that is subordinated in right of payment to the Obligations (excluding (a) the purchase, redemption, defeasance or other acquisition or retirement for value of Indebtedness (other than any payment in respect of intercompany
Indebtedness of Holdings or any Subsidiary thereof which will be governed by the subordination terms required for such Indebtedness pursuant to Section 8.03(7)) that is subordinated in right of payment to the Obligations purchased, redeemed,
defeased or otherwise acquired or retired for value in anticipation of satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of purchase, redemption, defeasance or other
acquisition or retirement for value, (b) other than any payment in respect of intercompany Indebtedness of Holdings or any Subsidiary thereof (which will be governed by the subordination terms required for such Indebtedness pursuant to
Section 8.03(7)), any payment of principal or interest at the Stated Maturity thereof and (c) any payment, purchase, redemption or other acquisition or retirement for value made with the prior written consent of the Administrative Agent,
provided that the aggregate amount of any payments, purchases, redemptions or other acquisitions or retirements made in reliance on this clause (c), when aggregated with the aggregate amount of all (x) payments, purchases, redemptions or
other acquisitions or retirements made in reliance on clause (5)(c)(ii) below and (y) prepayments, repayments, redemptions, defeasances or purchases made in reliance on Section 8.04(3)(b)(A), shall not exceed $35,000,000); or

 (4) make any Restricted Investment; or 

(5) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any
Indenture Notes (other than (a) at the Stated Maturity thereof, (b) pursuant to any covenant contained in either Indenture (in each case as in effect as of the date hereof) requiring Holdings to make an offer to holders of Indenture Notes
to purchase Indenture Notes in connection with a Change of Control or an Asset Sale in respect of Indenture Collateral or (c) with the prior written consent of the Administrative Agent) or Specified Junior Debt Issuances (other than (i) at
the Stated Maturity thereof or (ii) with the prior written consent of the Administrative Agent, provided that the aggregate amount of any payments, purchases, redemptions, defeasances or other acquisitions or retirements made in reliance
on this clause (ii), when aggregated with the aggregate amount of all (x) payments, purchases, redemptions or other acquisitions or retirements made in reliance on clause (3)(c) above and (y) prepayments, repayments, redemptions,
defeasances or purchases made in reliance on Section 8.04(3)(b)(A), shall not exceed $35,000,000) (all such payments and other actions set forth in these clauses (1) through (5) being collectively referred to as
“Restricted Payments”); 

  
 85 









 unless, at the time of and after giving effect to such Restricted Payment, no Default or Event of Default
has occurred and is continuing or would occur as a consequence of such Restricted Payment and: 
 (I) Holdings
would, at the time of such Restricted Payment immediately after giving pro forma effect thereto as if the same had occurred at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of Section 8.03; and 
 (II) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by Holdings and its Restricted Subsidiaries (excluding Restricted Payments permitted by
clauses (2), (3), (4), (5), (8), (9), (11) and (12) of the next succeeding paragraph) since the date of this Agreement, is less than the sum, without duplication, of: 

(a) 50% of the Consolidated Net Income of Holdings for the period (taken as one accounting period) from April 1,
2012 to the last day of Holdings’ last fiscal quarter ending prior to the date of the Restricted Payment for which internal financial statements are in existence at the time of such Restricted Payment (or, if such Consolidated Net Income for
such period shall be a loss, minus 100% of such loss); plus 
 (b) 100% of the aggregate net cash proceeds and
the Fair Market Value of any Capital Stock of Persons (other than Holdings or an Affiliate of Holdings) engaged primarily in the Oil and Gas Business or any other assets that are used or useful in the Oil and Gas Business, in each case received by
Holdings after the date of this Agreement as a contribution to its common equity capital or from the issue or sale after the date of this Agreement of Equity Interests of Holdings (other than Disqualified Stock) or from the issue or sale after the
date of this Agreement of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of Holdings that have been converted into or exchanged for such Equity Interests (other than Equity Interests (or Disqualified
Stock or debt securities) sold to a Subsidiary of Holdings) or received upon the exercise of any options, warrants or rights to purchase Equity Interests (other than Disqualified Stock) of Holdings, plus 

(c) the amount equal to the net reduction in Restricted Investments made by Holdings or any of its Restricted
Subsidiaries in any Person since the date of this Agreement resulting from: 

  
 86 









 (i) repurchases or redemptions of such Restricted Investments by such
Person, proceeds realized upon the sale of such Restricted Investment to a purchaser other than Holdings or a Subsidiary of Holdings, repayments of loans or advances or other transfers of assets (including by way of interest payments, dividend or
distribution) by such Person to Holdings or any Restricted Subsidiary of Holdings; plus 
 (ii) the
redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries or the merger or consolidation of an Unrestricted Subsidiary with and into Holdings or any Restricted Subsidiary (valued in each case as provided in the definition of
“Investment”) not to exceed, in the case of any Unrestricted Subsidiary, the amount of Investments previously made by Holdings or any Restricted Subsidiary of Holdings in such Unrestricted Subsidiary; plus 

(iii) an amount equal to any amount included as a Restricted Payment pursuant to clause (II) above on account of any
guarantee entered into by Holdings or any Restricted Subsidiary; to the extent that such guarantee has not been called upon and the obligation arising under such guarantee no longer exists or has been reduced; plus 

(iv) in the event Holdings or any Restricted Subsidiary makes any Investment in a Person that, as a result of or in
connection with such Investment, becomes a Restricted Subsidiary or is merged or consolidated with Holdings or a Restricted Subsidiary, an amount equal to the amount included as a Restricted Payment pursuant to clause (II) above on account of
Holdings’ or any Restricted Subsidiary’s Investment in such Person prior to the time it became a Restricted Subsidiary or the time of such merger or consolidation; plus 

(d) the amount by which Indebtedness of Holdings or its Restricted Subsidiaries is reduced on Holdings’ balance
sheet upon the conversion or exchange (other than by a Subsidiary of Holdings) subsequent to the date of this Agreement of any Indebtedness of Holdings or its Restricted Subsidiaries convertible into or exchangeable for Equity Interests of Holdings
(other than Disqualified Stock) (less the amount of cash, or the Fair Market Value of any other property, distributed by Holdings upon such conversion or exchange), 
 in the case of clauses (b) through (d) above, to the extent such amounts have not been included in Consolidated Net Income for the applicable period. 

The preceding provisions will not prohibit: 

  
 87 









 (1) the payment of any dividend or distribution within 60 days after the date of its
declaration, if at the date of declaration the payment would have complied with the provisions of this Agreement; 
 (2) the
purchase, redemption, defeasance or other acquisition or retirement for value of any subordinated Indebtedness, Indenture Notes or Specified Junior Debt Issuances of Holdings or any other Credit Party or of any Equity Interests of Holdings in

Holdings) of, Equity Interests of Holdings (other than Disqualified Stock), with a sale being deemed substantially concurrent if such purchase, redemption, defeasance or other acquisition or retirement for value occurs not more than 120 days after
such sale; provided, however, that the amount of any such net cash proceeds that are utilized for any such purchase, redemption, defeasance or other acquisition or retirement for value will be excluded or deducted from clause (II)
above; 
 (3) the purchase, redemption, defeasance or other acquisition or retirement for value of subordinated Indebtedness,

benefit plan or to satisfy obligations under any Equity Interests option plan or similar arrangement; provided, however, that the aggregate price paid for all such purchased, redeemed, acquired or retired Equity Interests may not
exceed $2,500,000 in any calendar year (with any portion of such $2,500,000 amount that is unused in any calendar year to be carried forward to successive calendar years and added to such amount) plus, to the extent not previously applied or
included, 
 (a) the cash proceeds received by Holdings or any of its Restricted Subsidiaries from sales of Equity Interests of
Holdings to employees, consultants or directors of Holdings or its Affiliates that occur after the date of this Agreement (to the extent the cash proceeds from the sale of such Equity Interests have not otherwise been applied to the payment of

 (a) in the case of a Change of Control, the purchase price therefor is not greater than 101% of the principal amount of such
Indebtedness and accrued and unpaid interest thereon; or 
 (b) in the case of an Asset Sale, the purchase price therefor is not

withholding obligation with respect to such exercise or vesting; 
 (10) payments to dissenting stockholders pursuant to
Applicable Law in connection with a consolidation, merger or transfer of assets in connection with a transaction that is not prohibited by this Agreement not to exceed $5,000,000 in the aggregate since the date of this Agreement;

and the Borrower made to allow Holdings or the Borrower to make interest and principal payments with respect to Holdings’ and the Borrower’s Indebtedness or to pay for their necessary or appropriate operating expenses; provided that
Holdings and the Borrower comply with the subordination terms required for such Indebtedness pursuant to Section 8.03(7), including the subordination terms providing that (a) no Default or Event of Default exists at the time of any such
Restricted Payment or would result therefrom and (b) the aggregate amount of payments made pursuant to this clause (11) may not exceed $125,000,000; 
 (12) the declaration and payment of dividends payable pursuant to the terms (as of the date of this Agreement) of Holdings’ Class C Convertible Preferred Stock outstanding on the date of this

 89 









 (13) so long as no Default (other than a Reporting Default) or Event of Default shall have
occurred and be continuing or would be caused thereby, other Restricted Payments (excluding those in clause (5) of the first paragraph of this Section 8.01) in an aggregate amount not to exceed $25,000,000 at any time outstanding
since the date of this Agreement (after giving effect to any dividends, interest payments, return of capital and subsequent reduction in the amount of any Investments made pursuant to this clause as a result of the repayment or other disposition
thereof, in an amount not to exceed the amount of such Investments previously made pursuant to in this clause); provided, however, that if any Investment pursuant to this clause (13) is made in any Person that is not a Restricted
Subsidiary of Holdings at the date of the making of such Investment and such Person becomes a Restricted Subsidiary of Holdings after such date, such Investment shall, subject to compliance with such clause (1), thereafter be deemed to have been
made pursuant to clause (1) of the definition of “Permitted Investments” and shall cease to have been made pursuant to this clause (13) for so long as such Person continues to be a Restricted Subsidiary. 

The amount of all Restricted Payments (other than cash) will be the Fair Market Value, on the date of the Restricted Payment, of the Restricted
Investment proposed to be made or asset(s) or securities proposed to be paid, transferred or issued by Holdings or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment, except that the amount of any non-cash Restricted
Payment referred to in the preceding clause (1) will be the Fair Market Value on the date of declaration. The Fair Market Value of any assets or securities that are required to be valued by this covenant will be determined by the method
prescribed in the definition of such term, except that the Fair Market Value of any non-cash consideration received from an Affiliate as a capital contribution for Equity Interests of Holdings shall be determined in good faith by the Board of
Directors of Holdings in the case of amounts of $10,000,000 or more, such determination to be based upon an opinion or appraisal issued by an accounting, appraisal or investment banking firm of national standing. For purposes of determining
compliance with this Section 8.01, in the event that a Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in the preceding clauses (1)-(12) or as a Permitted Investment,
Holdings will be permitted to divide or classify (or later divide, classify or reclassify in whole or in part in its sole discretion) such Restricted Payment in any manner that complies with this Section 8.01. 

8.02. Limitation on Dividend and Other Payment Restrictions Affecting Subsidiaries. Holdings will not, and will not permit any of
its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary of Holdings to:

Indebtedness or other obligations owed to Holdings or any of its Restricted Subsidiaries; 
 (2) make loans or advances to
Holdings or any of its Restricted Subsidiaries; or 
 (3) sell, lease or transfer any of its properties or assets to Holdings or
any of its Restricted Subsidiaries. 

  
 90 









 However, the preceding restrictions of this Section 8.02 will not apply to encumbrances or
restrictions existing under or by reason of: 
 (1) agreements (including those governing Existing Indebtedness) as in effect on
the date of this Agreement and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that the amendments, modifications, restatements, renewals, increases,
supplements, refundings, replacements or refinancings are no more restrictive, taken as a whole, with respect to such dividend, distribution and other payment restrictions than those contained in those agreements on the date of this Agreement, as
determined by the Board of Directors of Holdings in its reasonable and good faith judgment; 
 (2) this Agreement, the other
Credit Documents and the Indenture Documents; 
 (3) Applicable Law or similar restriction; 

(4) any agreement or instrument with respect to a Restricted Subsidiary that is not a Restricted Subsidiary of Holdings on the date of
this Agreement, in existence at the time such Person becomes a Restricted Subsidiary of Holdings and not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary; provided that such encumbrances and
restrictions are not applicable to Holdings or any Restricted Subsidiary or the properties or assets of Holdings or any Restricted Subsidiary other than such Subsidiary which is becoming a Restricted Subsidiary; 

(5) any agreement or instrument governing any Permitted Acquisition Indebtedness, so long as such agreement or instrument (A) was
not entered into in contemplation of the acquisition, merger or consolidation transaction related thereto, and (B) is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the properties or assets or
Subsidiaries of the Person, subject to such acquisition, merger or consolidation, so long as the agreement containing such restriction does not violate any other provision of this Agreement; 

(6) instruments or agreements governing Indebtedness of Holdings or any of the Restricted Subsidiaries permitted to be incurred pursuant
to an instrument or agreement entered into subsequent to the date of this Agreement in accordance with Section 8.03; provided that either (a) the encumbrance or restriction contained in the instrument or agreement governing
such Indebtedness applies only in the event of a payment default or a default with respect to a financial covenant in such Indebtedness or agreement or (b) the Board of Directors of Holdings determines in good faith that any such encumbrance or
restriction will not materially affect Holdings’ ability to make principal or interest payments on the Obligations; 
 (7)
(i) customary non-assignment provisions in Hydrocarbon purchase and sale or exchange agreements, joint operating agreements, or similar operational agreements or in licenses or leases entered into in the ordinary course of business, or (ii) in
the case of clause (3) of the preceding paragraph, other encumbrances or restrictions in agreements or instruments (including joint venture agreements, asset sale agreements, stock sale agreements and agreements of the type described in the
definition of “Permitted Business Investments”) relating 

  
 91 









 
to specific assets or property (and not to Indebtedness) that restrict generally the transfers of such assets or property, provided, however, that such other encumbrances or
restrictions do not materially impair the ability of Holdings to make scheduled payments on the Obligations when due and in each case entered into in the ordinary course of business or customary in the Oil and Gas Business; 

(8) Capital Lease Obligations, mortgage financings or purchase money obligations, in each case for property acquired in the ordinary
course of business or which is customary in the Oil and Gas Business that impose restrictions on that property purchased or leased of the nature described in clause (3) of the preceding paragraph; 

(9) any agreement for the sale or other disposition of a Restricted Subsidiary of Holdings that restricts distributions by that
Restricted Subsidiary pending its sale or other disposition; 
 (10) Permitted Refinancing Indebtedness; provided that
the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced, as determined
by the Board of Directors of Holdings in its reasonable and good faith judgment; 
 (11) Liens securing Indebtedness otherwise
permitted to be incurred under the provisions of Section 8.06 that limit the right of the debtor to dispose of the assets subject to such Liens; 
 (12) restrictions on cash, Cash Equivalents or other deposits or net worth imposed by customers or lessors under contracts or leases entered into in the ordinary course of business or which are customary
in the Oil and Gas Business; 
 (13) Hedging Agreements permitted from time to time under this Agreement; 

(14) any subordination of intercompany Indebtedness or other intercompany obligations (including any intercompany revolving credit)
owing from a Foreign Subsidiary of Holdings to a Domestic Subsidiary of Holdings to the claims or Liens (otherwise permitted by this Agreement) of any other creditor of such Foreign Subsidiary, including to the claims or Liens (otherwise permitted
by this Agreement) of any lender or other party to any Credit Facility (as a lender, letter of credit issuer or in any other capacity); and 
 (15) the issuance of preferred securities by any Restricted Subsidiary of Holdings or the payment of dividends thereon in accordance with the terms thereof; provided that issuance of such preferred
securities is permitted pursuant to Section 8.03 and the terms of such preferred securities do not expressly restrict the ability of a Restricted Subsidiary of Holdings to pay dividends or make any other distributions on its Equity
Interests (other than requirements to pay dividends or liquidation preferences on such preferred securities prior to paying any dividends or making any other distributions on such other Equity Interests). 

  
 92 









 8.03. Limitation on Incurrence of Indebtedness and Issuance of Preferred Stock.
Holdings will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to
(collectively, “incur”) any Indebtedness, Holdings will not issue any Disqualified Stock, and Holdings will not permit any of its Restricted Subsidiaries to issue any Disqualified Stock or preferred securities; provided,
however, that Holdings and any other Credit Party may incur Indebtedness (other than pursuant to the Existing Credit Agreement), Holdings may issue Disqualified Stock and any other Credit Party may issue Disqualified Stock or preferred
securities, if the Fixed Charge Coverage Ratio for Holdings’ most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or
such preferred securities or Disqualified Stock is issued, as the case may be, would have been at least 2.25 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness
had been incurred or such preferred securities or Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period. 
 The first paragraph of this Section 8.03 will not prohibit the incurrence of any of the following items of Indebtedness or the issuance of any Disqualified Stock or any preferred securities
described below (collectively, “Permitted Debt”): 
 (1) Indebtedness incurred pursuant to this
Agreement and the other Credit Documents; 
 (2) the incurrence by Holdings or any of the Restricted Subsidiaries
of additional unsecured Indebtedness under one or more Credit Facilities, provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness outstanding under Holdings and its Restricted
Subsidiaries’ Credit Facilities incurred under this clause (2) does not exceed: 
 (a) if
Holdings’ Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence are $2,000,000,000 or less, the greater of (i) $100,000,000 and (ii) 7.5% of Holdings’ Adjusted Consolidated Net Tangible Assets
determined as of such date; 
 (b) if Holdings’ Adjusted Consolidated Net Tangible Assets determined as of
the date of such incurrence are $3,000,000,000 or less, but exceed $2,000,000,000, the greater of (i) $100,000,000 and (ii) 10% of Holdings’ Adjusted Consolidated Net Tangible Assets determined as of such date; and 

(c) if Holdings’ Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence exceed
$3,000,000,000, the greater of (i) $100,000,000 and (ii) 15% of Holdings’ Adjusted Consolidated Net Tangible Assets determined as of such date; 
 (3) the incurrence by Holdings or its Restricted Subsidiaries of the Existing Indebtedness not otherwise referred to in this definition of “Permitted Debt”; 

  
 93 









 (4) the incurrence by Holdings of Indebtedness represented by the
Indenture Notes in an aggregate principal amount not to exceed $500,000,000 at any one time outstanding and the related guarantees of the Indenture Notes made by the Subsidiary Guarantors; 

(5) the incurrence by Holdings or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease
Obligations, mortgage financings or purchase money obligations, in each case incurred for the purpose of financing all or any part of the purchase price or cost of design, installation, repair, replacement, construction or improvement of property,
plant or equipment used in the business of Holdings or such Restricted Subsidiary (whether through the direct purchase of such assets or the Capital Stock of any Person owning such assets (but no other material assets)) and related financing costs,
and Attributable Debt in respect of Sale Leaseback Transactions, including all Permitted Refinancing Indebtedness incurred to extend, refinance, renew, replace, defease, discharge, refund or otherwise retire for value any Indebtedness incurred
pursuant to this clause (5), provided that after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred pursuant to this clause (5) and then outstanding does not exceed the greater of
(a) $25,000,000 and (b) 2.0% of Holdings’ Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence; 
 (6) the incurrence by Holdings or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which shall be used to extend, refinance, renew, replace,
defease, discharge, refund or otherwise retire for value, in whole or in part, Indebtedness of Holdings or any of its Restricted Subsidiaries (other than intercompany Indebtedness) or Disqualified Stock of Holdings, in each case that was permitted
by this Agreement to be incurred pursuant to the first paragraph of this Section 8.03 or clauses (3) (other than in respect of Indebtedness under the Existing Credit Agreement), (4) and (13) of this paragraph or this
clause (6); 
 (7) the incurrence by Holdings or any of its Restricted Subsidiaries of intercompany
Indebtedness between or among any of Holdings and any of its Restricted Subsidiaries; provided, however, that: 
 (a) if any Credit Party is the obligor on such Indebtedness, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations; and 

(b) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by
a Person other than Holdings or a Restricted Subsidiary of Holdings and (ii) any sale or other transfer of any such Indebtedness to a Person that is neither Holdings nor a Restricted Subsidiary of Holdings shall be deemed, in each case, to
constitute an incurrence (as of the date of such issuance, sale or transfer) of such Indebtedness by Holdings or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (7); 

  
 94 









 (8) the incurrence by Holdings or any of its Restricted Subsidiaries of
obligations under Hedging Agreements; 
 (9) (a) the guarantee by Holdings or any other Credit Party of
Indebtedness of Holdings or any other Credit Party that was permitted to be incurred by the first paragraph of this Section 8.03; provided that if the Indebtedness being guaranteed is subordinated to the Obligations, then the
Guaranty of Holdings or such other Credit Party (or, in the case of a guarantee made by the Borrower, the Borrower’s Obligations hereunder) shall be senior to its guarantee of such subordinated Indebtedness; and (b) the guarantee by
Holdings or any of its Restricted Subsidiaries of Indebtedness of Holdings or any of its Restricted Subsidiaries that was permitted to be incurred by another provision of this Section 8.03 other than the first paragraph hereof;
provided that if the Indebtedness being guaranteed is subordinated to the Obligations, then the Guaranty of Holdings or such other Credit Party (or, in the case of a guarantee made by the Borrower, the Borrower’s Obligations hereunder),
if it is a Guarantor, shall be senior to its guarantee of such subordinated Indebtedness; 
 (10) the incurrence
by Holdings or any of its Restricted Subsidiaries of Indebtedness relating to net gas balancing positions arising in the ordinary course of business and consistent with past practice; 

(11) the incurrence by Holdings or any of its Restricted Subsidiaries of Indebtedness in respect of bid, performance,
surety, appeal and similar bonds issued for the account of Holdings and any of its Restricted Subsidiaries in the ordinary course of business or which are customary in the Oil and Gas Business; 

(12) the issuance by any of Holdings’ Restricted Subsidiaries to Holdings or to any of its Restricted Subsidiaries of
any preferred securities; provided, however, that: 
 (a) any subsequent issuance or transfer of
Equity Interests that results in any such preferred securities being held by a Person other than Holdings or a Restricted Subsidiary of Holdings; and 
 (b) any sale or other transfer of any such preferred securities to a Person that is not either Holdings or a Restricted Subsidiary of Holdings shall be deemed, in each case, to constitute an issuance (as
of the date of such issuance, sale or transfer) of such preferred securities by such Restricted Subsidiary that was not permitted by this clause (12); 
 (13) Permitted Acquisition Indebtedness; 

  
 95 









 (14) the incurrence by Holdings or its Restricted Subsidiaries of
Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds in the ordinary course of business, so long as such Indebtedness is covered within
five Business Days; 
 (15) the incurrence by Holdings or its Restricted Subsidiaries of Indebtedness consisting
of the financing of insurance premiums in customary amounts consistent with the operations and business of Holdings and the Restricted Subsidiaries; and 
 (16) the incurrence by Holdings or any other Credit Party of additional Indebtedness or the issuance by Holdings of additional Disqualified Stock, provided that, after giving effect to any such
incurrence or issuance, the aggregate principal amount of all Indebtedness and Disqualified Stock incurred or issued under this clause (16) and then outstanding does not exceed the greater of (a) $75,000,000 and (b) 5.0% of
Holdings’ Adjusted Consolidated Net Tangible Assets determined as of the date of such incurrence or issuance. 
 Notwithstanding any of the
foregoing, Holdings shall not, and shall not permit any of its Restricted Subsidiaries to (and the provisions of this Section 8.03 shall not permit Holdings or any of its Restricted Subsidiaries to), incur any Indebtedness for borrowed
money having a maturity date occurring on or prior to the Maturity Date (determined disregarding the proviso contained therein). 
 For purposes
of determining compliance with this Section 8.03, in the event that an item of Indebtedness or Disqualified Stock or preferred securities meets the criteria of more than one of the categories of Permitted Debt described in
clauses (1) through (16) above, or is entitled to be incurred or issued pursuant to the first paragraph of this Section 8.03, Holdings will be permitted to divide and classify (or later classify, reclassify or re-divide in
whole or in part in its sole discretion) such item of Indebtedness or Disqualified Stock or preferred securities in any manner that complies with this Section 8.03; provided that (a) Indebtedness under this Agreement and the
other Credit Documents shall be considered to have been incurred under clause (1) above and (b) Indebtedness under the Existing Credit Agreement shall be considered to have been incurred under clause (3) above. For purposes of
determining any particular amount of Indebtedness under this covenant, guarantees of Indebtedness otherwise included in the determination of such amount shall not also be included except to the extent that such Indebtedness exceeds such guarantee.

 The accrual of interest, accrual of dividends, the accretion or amortization of original issue discount, the payment of interest on any
Indebtedness in the form of additional Indebtedness and the payment of dividends on Disqualified Stock or preferred securities in the form of additional shares of Disqualified Stock or preferred securities will not be deemed to be an incurrence of
Indebtedness or an issuance of Disqualified Stock or preferred securities for purposes of this Section 8.03. 

  
 96 









 For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of
Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency will be calculated based on the relevant currency exchange rate in effect on the date the Indebtedness was incurred, in the case of term
Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and the refinancing would cause the applicable
U.S. dollar-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of the refinancing, such U.S. dollar-dominated restriction shall be deemed not to have been exceeded so long as the principal
amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced (plus all accrued and unpaid interest on such Indebtedness, and the amount of all fees, expenses and premiums incurred in connection
therewith). Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that Holdings or any Restricted Subsidiary may incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations
in the exchange rate of currencies. The principal amount of any Permitted Refinancing Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, will be calculated based on the
currency exchange rate applicable to the currencies in which the Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing. 
 8.04. Limitation on Asset Sales. Holdings will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 

(1) Holdings (or the Restricted Subsidiary, as the case may be) receives consideration at least equal to the Fair Market
Value of the assets or Equity Interest issued or sold or otherwise disposed of; and 
 (2) at least 75% of the
aggregate consideration to be received by Holdings and its Restricted Subsidiaries in such Asset Sale (determined on the date of contractually agreeing to such Asset Sale) and any other Asset Sale since the date of this Agreement, on a cumulative
basis, is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash: 
 (a) any liabilities, as shown on Holdings’ or any Restricted Subsidiary’s most recent balance sheet, of Holdings or such Restricted Subsidiary (other than contingent liabilities and liabilities
that are by their terms subordinated in right of payment to the Obligations) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases Holdings or such Restricted Subsidiary from further
liability; and 
 (b) any securities, notes or other obligations received by Holdings or any Restricted
Subsidiary from such transferee that are, within 90 days after the Asset Sale, converted by Holdings or such Restricted Subsidiary into cash or Cash Equivalents, to the extent of the cash received in that conversion, 

  
 97 









 provided that in the case of any Asset Sale pursuant to a condemnation, appropriation or similar
governmental taking, including by deed in lieu of condemnation, such Asset Sale shall not be required to satisfy the requirements of items (1) and (2) above. Notwithstanding the preceding, the 75% limitation referred to above shall be
deemed satisfied with respect to any Asset Sale to which such limitation applies in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with the preceding provision on an after-tax basis, is
equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation. 

Within 365 days after the receipt of any Net Proceeds from an Asset Sale, Holdings (or the applicable Restricted Subsidiary, as the case may be) may
apply those Net Proceeds at its option to any combination of the following: 
 (1) prior to the Escrow Release
Date, to permanently prepay or repay Indebtedness outstanding under the Existing Credit Agreement in accordance with the terms thereof; 
 (2) to repay any Loans or other Obligations then outstanding hereunder; 
 (3) with the prior written consent of the Administrative Agent (unless such Net Proceeds are from Asset Sales of Indenture Collateral, in which case such consent shall not be required), to permanently
prepay, repay, redeem, defease or purchase the Indenture Notes or any other Indebtedness of Holdings or any of its Restricted Subsidiaries permitted to be incurred under the terms of this Agreement and, in each case, any obligations with respect
thereto (subject to limitations in Section 8.01); provided that (a) Indebtedness permitted to be prepaid, repaid, redeemed, defeased or purchased pursuant to this clause (3) shall in no circumstances include
(x) Indebtedness described in preceding clauses (1) or (2), (y) any intercompany Indebtedness of Holdings or any of its Restricted Subsidiaries to Holdings or any of its Affiliates or (z) any trade payables or taxes owed or owing
by Holdings or any of its Restricted Subsidiaries and (b) the aggregate amount of all prepayments, repayments, redemptions, defeasances or purchases pursuant to this clause (3) from and after the Effective Date (other than with Net
Proceeds of Asset Sales of Indenture Collateral) shall not exceed an amount equal to (A) $35,000,000, less (B) the aggregate amount of all payments, purchases, redemptions or other acquisitions or retirements made in reliance on
Section 8.01(5)(c)(ii) and Section 8.01(3)(c) plus (C) the aggregate amount of Commitment reductions that are rejected by the Lenders pursuant to the third succeeding paragraph (it being understood that any such
prepayments, redemptions, defeasances or purchases pursuant to this sub-clause (C) shall be subject to the prior written consent of the Administrative Agent); 

(4) subject to compliance with the Additional Guarantor Requirement as of the date of such investment, to invest in or
acquire Additional Assets; or 

  
 98 









 (5) to make capital expenditures in respect of Holdings’ or its
Restricted Subsidiaries’ Oil and Gas Business. 
 The requirement of clause (4) or (5) immediately above shall be deemed to be
satisfied if a bona fide binding contract committing to make the investment, acquisition or expenditure referred to therein is entered into by Holdings or any of its Restricted Subsidiaries with a Person other than an Affiliate of Holdings within
the time period specified above in this paragraph and such Net Proceeds are subsequently applied in accordance with such contract within six months following the date such agreement is entered into. 

Pending the final application of any Net Proceeds, Holdings or any Restricted Subsidiary of Holdings may invest the Net Proceeds in any manner that is
not prohibited by this Agreement. “Excess Proceeds” shall mean any and all Net Proceeds from Asset Sales that are not applied or invested as provided in the second preceding paragraph. 

On the 366th day after an Asset Sale (or, at Holdings’s option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds
$10,000,000, the Total Commitment shall be reduced by the amount of such Excess Proceeds in accordance with this paragraph. The Borrower shall notify the Administrative Agent in writing of any reduction in the Total Commitment required to be made
pursuant to the preceding sentence at least (5) five Business Days prior to the date of such reduction. Each such notice shall specify the date of such reduction and provide a reasonably detailed calculation of the amount of such reduction. The
Administrative Agent will promptly notify each Lender of the contents of the Borrower’s Commitment reduction notice and of such Lender’s pro rata share of the Commitment reduction. Each Lender may reject all or a portion of its pro rata
share of any such Commitment reduction by providing written notice (each, a “Rejection Notice”) to the Administrative Agent and the Borrower no later than 5:00 p.m. one (1) Business Day after the date of such Lender’s
receipt of notice from the Administrative Agent regarding such Commitment reduction. Each Rejection Notice from a given Lender shall specify the principal amount of the Commitment reduction to be rejected by such Lender. If a Lender fails to deliver
a Rejection Notice to the Administrative Agent within the time frame specified above or such Rejection Notice fails to specify the principal amount of the Loans to be rejected, any such failure will be deemed an acceptance of the total amount of
such Commitment reduction. 
 If, on the date of any reduction in the Commitments pursuant to the immediately preceding paragraph in respect of
which one or more Rejection Notices have been delivered, there are any Loans outstanding, such Loans shall on or prior to the effectiveness of such Commitment decrease be prepaid from the proceeds of additional Loans made hereunder (reflecting such
decrease in Commitments), which prepayment shall be accompanied by accrued interest on the Loans being prepaid and any costs incurred by any Lender in accordance with Section 2.10. The Administrative Agent and the Lenders hereby agree
that the minimum borrowing, pro rata borrowing and pro rata payment requirements contained elsewhere in this Agreement shall not apply to the transactions effected pursuant to the immediately preceding sentence. 

8.05. Limitation on Transactions with Affiliates. Holdings will not, and will not permit any of its Restricted Subsidiaries to,
make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any properties or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or
guarantee with, or for the benefit of, any Affiliate of Holdings (each, an “Affiliate Transaction”), unless: 

  
 99 









 (1) the Affiliate Transaction is on terms that are not less favorable to
Holdings or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by Holdings or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of Holdings’ Board of
Directors, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to Holdings or the relevant Restricted Subsidiary from a financial point of view; and 

(2) Holdings delivers to the Administrative Agent: 

(a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration to or from an Affiliate in excess of $10,000,000, a resolution of the Board of Directors of Holdings set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions
complies with this Section 8.05 and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors of Holdings; and 

(b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration to or from an Affiliate in excess of $20,000,000, an opinion as to the fairness to Holdings or such Restricted Subsidiary of such Affiliate Transaction or series of related Affiliate Transactions from a financial point of view issued
by an accounting, appraisal or investment banking firm of national standing. 
 The following items will not be deemed to be Affiliate
Transactions and, therefore, will not be subject to the provisions of the prior paragraph of this Section 8.05: 
 (1) any employment agreement or arrangement, equity award, equity option or cash or equity settled equity appreciation agreement or plan, employee benefit plan, officer or director indemnification
agreement, severance agreement, consulting agreement or other compensation plan or arrangement entered into by Holdings or any of its Restricted Subsidiaries in the ordinary course of business or which is customary in the Oil and Gas Business, and
payments, awards, grants or issuances of securities pursuant thereto; 
 (2) transactions between or among any of
Holdings and its Restricted Subsidiaries; 
 (3) transactions with a Person (other than an Unrestricted
Subsidiary of Holdings) that is an Affiliate of Holdings solely because Holdings owns, directly or indirectly, an Equity Interest in, or otherwise controls, such Person or has nominated or appointed a person to the Board of Directors of that Person;


  
 100









 (4) customary compensation, indemnification and other benefits made
available to officers, directors, employees or consultants of Holdings or a Restricted Subsidiary of Holdings, including reimbursement or advancement of out-of-pocket expenses and provisions of officers’ and directors’ liability insurance;

 (5) issuances of Equity Interests (other than Disqualified Stock) of Holdings to, or receipt of capital
contributions from, Affiliates of Holdings and any dividend or distribution payable in Equity Interests (other than Disqualified Stock) of Holdings; 
 (6) any Permitted Investments or Restricted Payments that are permitted by Section 8.01; 
 (7) transactions between Holdings or any of its Restricted Subsidiaries and any Person that would not otherwise constitute an Affiliate Transaction except for the fact that one director of such other
Person is also a director of Holdings or such Restricted Subsidiary, as applicable; provided that such director abstains from voting as a director of Holdings or such Restricted Subsidiary, as applicable, on any matter involving such other
Person; 
 (8) the existence of, and the performance of obligations of Holdings or any of its Restricted
Subsidiaries under the terms of, any written agreement to which Holdings or any of its Restricted Subsidiaries is a party on the date of this Agreement, as such agreements may be amended, modified, supplemented or replaced from time to time;
provided, however, that any amendment, modification, supplement or replacement entered into after the date of this Agreement will be permitted to the extent that its terms are not materially more disadvantageous, taken as a whole, to
the Lenders than the terms of the agreements in effect on the date of this Agreement (as conclusively evidenced by a Board Resolution of Holdings or such Subsidiary); 

(9) any transaction in which Holdings or any of its Restricted Subsidiaries, as the case may be, delivers to the
Administrative Agent an opinion from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to Holdings or such Restricted Subsidiary from a financial point of view or that such transaction
meets the requirements of clause (1) of the preceding paragraph of this Section 8.05; 
 (10)
(a) guarantees by Holdings or any of its Restricted Subsidiaries of performance of obligations of Holdings’ Unrestricted Subsidiaries in the ordinary course of business or which are customary in the Oil and Gas Business and (b) pledges by
Holdings or any Restricted Subsidiary of Holdings of Equity Interests in Unrestricted Subsidiaries for the benefit of lenders or other creditors of Holdings’ Unrestricted Subsidiaries; 

  
 101









 (11) any Affiliate Transaction with a Person in its capacity as a holder of
Indebtedness or Capital Stock of Holdings or any Restricted Subsidiary of Holdings if such Person is treated no more favorably than the other holders of Indebtedness or Capital Stock of Holdings or such Restricted Subsidiary; 

(12) transactions with joint venture partners, customers, clients, suppliers or purchasers or sellers of goods or
services, or lessors or lessees of property, in each case in the ordinary course of business or which are customary in the Oil and Gas Business and otherwise in compliance with the terms of this Agreement similar to those contained in similar
contracts entered into by Holdings or any Restricted Subsidiary and unrelated third parties, or if neither Holdings nor any Restricted Subsidiary has entered into a similar contract with an unrelated third party, which are, in the aggregate (taking
into account all the costs and benefits associated with such transactions), not materially less favorable to Holdings and its Restricted Subsidiaries than those that would have been obtained in a comparable transaction by Holdings or such Restricted
Subsidiary with an unrelated third party, in the good faith determination of Holdings’ Board of Directors or any executive officer of Holdings involved in or otherwise familiar with such transaction; and 

(13) dividends and distributions to Holdings and its Restricted Subsidiaries by any Unrestricted Subsidiary. 

8.06. Limitation on Liens. Holdings will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or
otherwise cause or suffer to exist or become effective (a) any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets other than the Designated Collateral (whether now owned or hereafter
acquired), unless the Obligations of the Borrower or (in the case of such a Lien with respect to a Guarantor) the Applicable Guaranty are secured on an equal and ratable basis with (or, if such Lien secures obligations subordinated in right of
payment to the Obligations of the Borrower or such Guaranty, on a basis senior (to at least the same extent as the Obligations of the Borrower or such Guaranty are senior in right of payment) to) the obligations so secured until such time as such
obligations are no longer secured by a Lien, (b) any Lien of any kind securing Indebtedness upon any of the Indenture Collateral (whether now owned or hereafter acquired), other than the Indenture Notes or (c) any Lien of any kind (other
than Permitted Liens) securing Indebtedness upon the Collateral. 
 Any Lien on any property or assets of Holdings or any of its
Restricted Subsidiaries created for the benefit of the Secured Creditors pursuant to clause (a) of the preceding paragraph shall provide by its terms that such Lien shall, except to the extent that such property or assets are subject to a Lien
created for the benefit of the Secured Creditors in accordance with Section 7.12 (in which case such property and assets shall be subject to clause (c) of the preceding paragraph), be automatically and unconditionally released and
discharged at such time as there are no other Liens of any kind (other than Permitted Liens) on such property or assets securing Indebtedness. 

  
 102









 8.07. Business Activities. Holdings shall not, and shall not permit any Restricted
Subsidiary to, engage in any business other than the Oil and Gas Business, except to such extent as would not be material to Holdings and its Restricted Subsidiaries taken as a whole. 

8.08. Designation of Restricted and Unrestricted Subsidiaries. The Board of Directors of Holdings may designate any Restricted
Subsidiary of Holdings (other than the Borrower) to be an Unrestricted Subsidiary if that designation would not cause a Default or Event of Default and the other requirements for such designation prescribed in the definition of “Unrestricted
Subsidiary” are satisfied. If a Restricted Subsidiary of Holdings is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by Holdings and its Restricted Subsidiaries in the Subsidiary
properly designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the first paragraph of Section 8.01 or
represent Permitted Investments, as determined by Holdings. That designation shall only be permitted if the Investment would be permitted at that time and if the Subsidiary so designated otherwise meets the definition of an Unrestricted Subsidiary.

 The Board of Directors of Holdings may at any time designate any Unrestricted Subsidiary of Holdings to be a Restricted
Subsidiary of Holdings, provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of Holdings of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only
be permitted if (1) such Indebtedness is permitted under Section 8.03, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period, and (2) no Default (other than a
Reporting Default) or Event of Default would be in existence following such designation. 
 8.09. Merger, Consolidation, or Sale
of Assets. Neither Holdings nor the Borrower may: (x) consolidate or merge with or into another Person (whether or not Holdings or the Borrower (as applicable) is the survivor), convert into another form of entity or continue in another
jurisdiction; or (y) directly or indirectly, sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions to another Person, unless: 

(a) either (1) Holdings or the Borrower (as applicable) is the survivor or (2) the Person formed by or surviving any such
consolidation or merger or resulting from such conversion (if other than Holdings or the Borrower) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation, limited liability company
or limited partnership organized or existing under the laws of the United States, any state of the United States or the District of Columbia or, in the case of any such merger or consolidation involving the Borrower, or any sale, assignment,
transfer, lease, conveyance or other disposition of assets of the Borrower, organized or existing under the laws of England and Wales (Holdings, the Borrower or such other Person, as the case may be, being herein called the “Successor
Company”); 
 (b) the Successor Company unconditionally assumes all the obligations of Holdings or the Borrower (as
applicable) under this Agreement, the Security Documents and any and all other Credit Documents to which it is a party pursuant to a joinder agreement or other agreement in a form reasonably satisfactory to the Administrative Agent; 

  
 103









 (c) immediately after such transaction or transactions, no Default (other than a Reporting
Default) or Event of Default exists; 
 (d) either 
 (i) the Successor Company would, on the date of such transaction immediately after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of
the applicable four-quarter period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of Section 8.03 hereof; or 

(ii) immediately after giving pro forma effect to such transaction and any related financing transactions as if the same had occurred at
the beginning of the applicable four-quarter period, the Fixed Charge Coverage Ratio of the Successor Company, will be equal to or greater than the Fixed Charge Coverage Ratio of Holdings immediately prior to such transaction; 

(e) the Successor Company causes such amendments, supplements or other instruments to be executed, delivered, filed and recorded, as
applicable, in such jurisdictions as may be required by applicable law or desired by the Collateral Agent to preserve and protect the Lien of the Security Documents on any Collateral owned by or transferred to the Successor Company; 

(f) any Collateral owned by or transferred to the Successor Company shall (1) continue to constitute Collateral, (2) be subject
to a first-priority Lien in favor of the Collateral Agent for the benefit of the Secured Creditors and (3) not be subject to any Lien other than the Liens securing the Obligations and other Permitted Liens; and 

(g) the property and assets of the Person which is merged or consolidated with or into the Successor Company, to the extent that they are
property or assets of the types which would constitute Collateral, shall be treated as after-acquired property and the Successor Company shall take such action as may be reasonably necessary or desired by the Collateral Agent to cause such property
and assets to be made subject to a first-priority Lien in favor of the Collateral Agent for the benefit of the Secured Creditors. 
 Notwithstanding the restrictions described in the foregoing clause (d), (x) any Restricted Subsidiary of Holdings (other than the Borrower) may consolidate with, merge into or dispose of all or
part of its properties or assets to Holdings or another Restricted Subsidiary, in each case, subject to compliance with the Additional Guarantor Requirement as of the time of such merger or disposition, and (y) Holdings may merge with or into
an Affiliate formed solely for the purpose of reincorporating Holdings in another jurisdiction. 
 For purposes of the
foregoing, the sale, assignment, transfer, lease, conveyance or other disposition (in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Subsidiaries of Holdings, which properties
or assets, if held by Holdings instead of such Subsidiaries, would constitute all or substantially all of the properties or assets of Holdings on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties
or assets of Holdings. 

  
 104









 8.10. Elections. Without the prior written consent of the Required Lenders, Holdings
will not, and will not permit any of its Subsidiaries to, make any election for U.S. federal income tax purposes that causes the Indebtedness of the Borrower to be treated as the Indebtedness of a “U.S. person” (as such term is defined
under Section 7701(a)(30) of the Code) for U.S. federal income tax purposes. 
 SECTION 8A. Negative Covenants Prior to
the Escrow Release Date. Each of Holdings and the Borrower covenants and agrees that, on and from the Effective Date until the Escrow Release Date: 
 (a) Holdings and the Borrower will each (i) comply, and cause each of their Subsidiaries to comply, with the covenants set forth in Section 8 of the Existing Credit Agreement as in effect on the
Effective Date as if such covenants were set forth herein in full, mutatis mutandis and (ii) take or refrain from taking, as the case may be, and will cause each of their Subsidiaries to take or refrain from taking, as the case may be, all
actions that are necessary to be taken or not taken so that no such Person is in violation of any covenants set forth in Section 8 of the Existing Credit Agreement as in effect on the Effective Date (as incorporated herein by reference), and
that so no Default or Event of Default (each as defined in the Existing Credit Agreement as in effect on the Effective Date) is caused by the actions of any such Person. 
 (b) Holdings shall not, and shall not permit any of its Restricted Subsidiaries to, incur any Indebtedness for borrowed money having a maturity date occurring on or prior to the Maturity Date (determined
disregarding the proviso contained therein); and 
 (c) Holdings will not, and will not permit any of its Restricted
Subsidiaries to, create, incur, assume or otherwise cause to suffer or exist or become effective any Lien of any kind securing Indebtedness which Lien is subordinated or junior in priority to the Lien securing Indebtedness evidenced by the Existing
Credit Agreement unless such Lien is subordinated in priority to the Lien securing the Obligations.

to be (or shall become) due and payable, or required to be prepaid other than by a regularly scheduled required prepayment, prior to the stated maturity thereof; provided that, it shall not be a Default or an Event of Default under this

term “Administrative Agent” also shall include Cyan Partners, LP, in its capacity as Collateral Agent pursuant to the Security Documents) to act as specified herein and in the other Credit Documents. Each Lender hereby irrevocably
authorizes, and each holder of any Note by the acceptance of such Note shall be deemed irrevocably to authorize the Administrative Agent to take such action on its behalf under the provisions of this Agreement, the other Credit Documents and any
other instruments and agreements referred to herein or therein and to exercise such powers and to perform such duties hereunder and thereunder as are specifically delegated to or required of the Administrative Agent by the terms hereof and thereof

 109









 10.02. Nature of Duties. (a) The Administrative Agent in its capacity as such
shall have no duties or responsibilities except those expressly set forth in this Agreement and in the other Credit Documents. Neither the Administrative Agent in its capacity as such nor any of its officers, directors, agents, employees or
affiliates shall be liable for any action taken or omitted by it or them hereunder or under any other Credit Document or in connection herewith or therewith, unless caused by its or their gross negligence or willful misconduct (as determined by a
court of competent jurisdiction in a final and non-appealable decision). The duties of the Administrative Agent shall be mechanical and administrative in nature; the Administrative Agent shall not have by reason of this Agreement or any other Credit
Document a fiduciary relationship in respect of any Lender or the holder of any Note; and nothing in this Agreement or in any other Credit Document, expressed or implied, is intended to or shall be so construed as to impose upon the Administrative
Agent any obligations in respect of this Agreement or any other Credit Document except as expressly set forth herein or therein. 
 (b) Notwithstanding any other provision of this Agreement or any provision of any other Credit Document, the Lead Arranger is named as such for recognition purposes only, and in its capacity as such shall
have no powers, duties, responsibilities or liabilities with respect to this Agreement or the other Credit Documents or the transactions contemplated hereby and thereby; it being understood and agreed that the Lead Arranger shall be entitled to all
indemnification and reimbursement rights in favor of the Administrative Agent as, and to the extent, provided for under Sections 10.06 and 11.01. Without limitation of the foregoing, the Lead Arranger shall not, solely by reason of
this Agreement or any other Credit Documents, have any fiduciary relationship in respect of any Lender or any other Person. 

10.03. Lack of Reliance on the Administrative Agent. Each Lender from time to time party to this Agreement (i) confirms that
it has received a copy of this Agreement and the other Credit Documents, together with copies of the financial statements referred to therein, and such other documents and information as it has deemed appropriate to make its own credit analysis and
decision to become a Lender under this Agreement, (ii) agrees that it has made and will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Credit Documents and, except as expressly provided in this Agreement, the Administrative Agent shall not have any
duty or responsibility, either initially or on a continuing basis, to provide any Lender or the holder of any Note with any credit or other information with respect thereto, whether coming into its possession before the making of the Loans or at any
time or times thereafter, (iii) acknowledges and agrees that no fiduciary or advisory relationship between the Administrative Agent and any Lender is intended to be or has been created in respect of any of the transactions contemplated by this
Agreement, (iv) acknowledges and agrees that the Administrative Agent, on the one hand, and each Lender on the other hand, have an arms-length business relationship that does not directly or indirectly give rise to, and no Lender relies on, any
fiduciary duty on the Administrative Agent’s part, (v) acknowledges and agrees that each Lender is capable of evaluating and understanding, and each such Lender understands and accepts, the terms, risks and conditions of the transactions
contemplated by this Agreement, (vi) acknowledges and agrees that the Administrative Agent or any of its Affiliates may have received fees or other compensation from Holdings or any of its Affiliates in connection with this Agreement which may
or may not be publicly disclosed and such fees or compensation do 

  
 110









 
not affect any Lender’s independent credit decision to enter into the transactions contemplated by this Agreement, (vii) acknowledges and agrees that notwithstanding that no fiduciary
or similar relationship exists between the Administrative Agent and any Lender, each such Lender hereby waives, to the fullest extent permitted by law, any claims it may have against the Administrative Agent or its Affiliates for breach of fiduciary
duty or alleged breach of fiduciary duty and agrees that the Administrative Agent and its Affiliates shall have no liability (whether direct or indirect) to any Lender in respect of such a fiduciary duty claim or to any Person asserting a fiduciary
duty claim on behalf of or in right of any Lender, including any such Lender’s stockholders, employees or creditors, and (viii) agrees that it will perform in accordance with their terms all of the obligations which by the terms of this
Agreement and the other Credit Documents are required to be performed by it as a Lender. The Administrative Agent shall not be responsible to any Lender or the holder of any Note for any recitals, statements, information, representations or
warranties herein or in any document, certificate or other writing delivered in connection herewith or for the execution, effectiveness, genuineness, validity, enforceability, perfection, collectability, priority or sufficiency of this Agreement or
any other Credit Document or the financial condition of Holdings or any of its Subsidiaries or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement or any
other Credit Document, or the financial condition of Holdings or any of its Subsidiaries or the existence or possible existence of any Default or Event of Default. 
 10.04. Certain Rights of the Agents. If any Agent shall request instructions from the Required Lenders with respect to any act or action (including failure to act) in connection with this Agreement
or any other Credit Document, such Agent shall be entitled to refrain from such act or taking such action unless and until such Agent shall have received instructions from the Required Lenders; and such Agent shall not incur liability to any Lender
by reason of so refraining. Without limiting the foregoing, neither any Lender nor the holder of any Note shall have any right of action whatsoever against such Agent as a result of such Agent acting or refraining from acting hereunder or under any
other Credit Document in accordance with the instructions of the Required Lenders. 
 10.05. Reliance. The Administrative
Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, statement, certificate, telex, teletype or telecopier message, cablegram, radiogram, order or other document or telephone message
signed, sent or made by any Person that the Administrative Agent believed to be the proper Person, and, with respect to all legal matters pertaining to this Agreement and any other Credit Document and its duties hereunder and thereunder, upon advice
of counsel selected by the Administrative Agent. 
 10.06. Indemnification. To the extent the Administrative Agent (or
any affiliate, officer, director, employee, representative, agent, sub-agent or advisor thereof (each, a “Related Party”)) is not reimbursed and indemnified by the Borrower, the Lenders will reimburse and indemnify the
Administrative Agent (and any such Related Party) in proportion to their respective “percentage” as used in determining the Required Lenders (determined as if there were no Defaulting Lenders) for and against any and all liabilities,
obligations, losses, damages, penalties, claims, actions, judgments, costs, expenses or disbursements of whatsoever kind or nature which may be imposed on, asserted against or incurred by the Administrative Agent (or 

  
 111









 
any such Related Party) in performing its duties hereunder or under any other Credit Document or in any way relating to or arising out of this Agreement or any other Credit Document;
provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, claims, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s (or such
affiliates’ thereof) gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable decision). 
 10.07. Each Agent in its Individual Capacity. With respect to its obligation to make Loans under this Agreement, each Agent shall have the rights and powers specified herein for a
“Lender” and may exercise the same rights and powers as though it were not performing the duties specified herein; and the term “Lender,” “Required Lenders,” “Supermajority
Lenders,” “holders of Notes” or any similar terms shall, unless the context clearly indicates otherwise, include such Agent in its individual capacity. Each Agent and its affiliates may accept deposits from, lend money to,
and generally engage in any kind of banking, investment banking, trust or other business with, or provide debt financing, equity capital or other services (including financial advisory services) to any Credit Party or any Affiliate of any Credit
Party (or any Person engaged in a similar business with any Credit Party or any Affiliate thereof) as if they were not performing the duties specified herein, and may accept fees and other consideration from any Credit Party or any Affiliate of any
Credit Party for services in connection with this Agreement and otherwise without having to account for the same to the Lenders. 
 10.08. Holders. Any Agent may deem and treat the payee of any Note as the owner thereof for all purposes hereof unless and until a written notice of the assignment, transfer or endorsement thereof,
as the case may be, shall have been filed with the Administrative Agent. Any request, authority or consent of any Person who, at the time of making such request or giving such authority or consent, is the holder of any Note shall be conclusive and
binding on any subsequent holder, transferee, assignee or endorsee, as the case may be, of such Note or of any Note or Notes issued in exchange therefor. 
 10.09. Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Credit Document by or through any one or
more sub-agents appointed by the Administrative Agent (including, without limitation, Citigroup or any of its Affiliates). The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or
through their respective Related Parties. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable
judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agents. 

10.10. Resignation by and Replacement of the Administrative Agent. (a) The Administrative Agent may resign from the
performance of all of its respective functions and duties hereunder and/or under the other Credit Documents at any time by giving 15 Business Days’ prior written notice to the Lenders and, unless an Event of Default then exists, the Borrower.
Any such resignation by an Administrative Agent hereunder shall also constitute its resignation as the Collateral Agent, and upon the effectiveness of such resignation of an Administrative Agent in accordance with this Section 10.09 the
resigning Administrative Agent shall no longer be required to discharge any duties of the “Collateral Agent” under the Security Documents. Such resignation shall take effect upon the appointment of a successor Administrative Agent pursuant
to clauses (b) and (c) or (f) below or as otherwise provided below. 

  
 112









 (b) Except in the case of clause (f) below, upon any such notice of resignation by the
Administrative Agent, the Required Lenders shall appoint a successor Administrative Agent hereunder or thereunder who shall be a commercial bank or trust company reasonably acceptable to the Borrower, which acceptance shall not be unreasonably
withheld or delayed (provided that the Borrower’s approval shall not be required if an Event of Default then exists). 
 (c) If a successor Administrative Agent shall not have been so appointed pursuant to preceding clause (b) within such 15 Business Day period, the Administrative Agent, with the consent of the
Borrower (which consent shall not be unreasonably withheld or delayed, provided that the Borrower’s consent shall not be required if an Event of Default then exists), shall then appoint a successor Administrative Agent who shall serve as
Administrative Agent hereunder or thereunder until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided above. 
 (d) If no successor Administrative Agent has been appointed pursuant to clause (b) or (c) above by the 20th Business Day after the date such notice of resignation was given by the Administrative
Agent, the Administrative Agent’s resignation shall become effective and the Required Lenders shall thereafter perform all the duties of the Administrative Agent hereunder and/or under any other Credit Document until such time, if any, as the
Required Lenders appoint a successor Administrative Agent as provided above. 
 (e) Upon a resignation of the Administrative
Agent (and the Collateral Agent) pursuant to this Section 10.09, the Administrative Agent (and the Collateral Agent) shall remain indemnified to the extent provided in this Agreement and the other Credit Documents and the provisions of
this Section 10 (and the analogous provisions of the other Credit Documents) shall continue in effect for the benefit of the Administrative Agent (and the Collateral Agent) for all of its actions and inactions while serving as the
Administrative Agent (and the Collateral Agent). 
 (f) Cyan Partners, LP may by giving (5) five days’ written notice
to the Borrower designate any Person employing, or otherwise affiliated with, any one or more Persons who were, as of the date hereof, principals of Cyan Partners, LP, to act as Administrative Agent hereunder, in which case Cyan Partners, LP shall
be deemed to have resigned as Administrative Agent pursuant to preceding clause (a) and such designee shall be deemed to have been appointed as a successor Administrative Agent pursuant to preceding clause (b). 

10.11. Collateral Matters. (a) Each Lender authorizes and directs the Collateral Agent to enter into the Subsidiaries
Guaranty and Security Documents for the benefit of the Lenders and the other Secured Creditors. Each Lender hereby agrees, and each holder of any Note by the acceptance thereof will be deemed to agree, that, except as otherwise set forth herein, any
action taken by the Required Lenders in accordance with the provisions of this Agreement or the Security Documents, and the exercise by the Required Lenders of the powers set forth herein or therein, together with such other powers as are reasonably
incidental thereto, 

  
 113









 
shall be authorized and binding upon all of the Lenders. The Collateral Agent is hereby authorized on behalf of all of the Lenders, without the necessity of any notice to or further consent from
any Lender, from time to time prior to an Event of Default, to take any action with respect to any Collateral or Security Documents which may be necessary to perfect and maintain perfected the security interest in and liens upon the Collateral
granted pursuant to the Security Documents. 
 (b) The Lenders hereby authorize the Collateral Agent, at its option and in its
discretion, to release any Lien granted to or held by the Collateral Agent upon any Collateral (i) upon termination of the Total Commitment and payment and satisfaction of all of the Obligations (other than inchoate indemnification obligations)
at any time arising under or in respect of this Agreement or the Credit Documents or the transactions contemplated hereby or thereby, (ii) constituting property being sold or otherwise disposed of (to Persons other than Holdings and its
Subsidiaries) upon the sale or other disposition thereof in compliance with Section 8.04 or Section 8.02 of the Existing Credit Agreement, as applicable, (iii) if approved, authorized or ratified in writing by the
Required Lenders (or all of the Lenders hereunder, to the extent required by Section 11.12) or (iv) as otherwise may be expressly provided in the relevant Security Documents. Upon request by the Administrative Agent at any time, the
Lenders will confirm in writing the Collateral Agent’s authority to release particular types or items of Collateral pursuant to this Section 10.11. 
 (c) In connection with the granting of Permitted Liens by Holdings or any of its Restricted Subsidiaries, the Collateral Agent shall, to the extent requested by (and at the expense of) the Borrower,
execute appropriate Lien releases or lien subordination agreements in favor of the holder or holders of such Liens, in each case in form and substance satisfactory to the Collateral Agent and solely with respect to the item or items of equipment or
other assets subject to such Liens. 
 (d) The Collateral Agent shall have no obligation whatsoever to the Lenders or to any
other Person to assure that the Collateral exists or is owned by any Credit Party or is cared for, protected or insured or that the Liens granted to the Collateral Agent herein or pursuant hereto have been properly or sufficiently or lawfully
created, perfected, protected or enforced or are entitled to any particular priority, or to exercise or to continue exercising at all or in any manner or under any duty of care, disclosure or fidelity any of the rights, authorities and powers
granted or available to the Collateral Agent in this Section 10.11 or in any of the Security Documents, it being understood and agreed that in respect of the Collateral, or any act, omission or event related thereto, the Collateral Agent
may act in any manner it may deem appropriate, in its sole discretion, given the Collateral Agent’s own interest in the Collateral as one of the Lenders and that the Collateral Agent shall have no duty or liability whatsoever to the Lenders,
except for its gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and non-appealable decision). 
 10.12. Delivery of Information. The Administrative Agent shall not be required to deliver to any Lender originals or copies of any documents, instruments, notices, communications or other
information received by the Administrative Agent from any Credit Party, any Subsidiary thereof, the Required Lenders, any Lender or any other Person under or in connection with this Agreement or any other Credit Document except (a) as
specifically 

  
 114









 
provided in this Agreement or any other Credit Document and (b) as specifically requested from time to time in writing by any Lender with respect to a specific document, instrument, notice
or other written communication received by and in the possession of the Administrative Agent at the time of receipt of such request and then only in accordance with such specific request. 

SECTION 11. Miscellaneous. 
 11.01. Payment of Expenses, etc. (a) The Borrower hereby agrees to: (i) whether or not the transactions herein contemplated are consummated, pay all reasonable out-of-pocket costs and expenses
of the Administrative Agent (including, without limitation, the reasonable fees and disbursements of White & Case LLP and the Administrative Agent’s other counsel and consultants) in connection with the preparation, execution, delivery
and administration of this Agreement and the other Credit Documents and the documents and instruments referred to herein and therein and any amendment, waiver or consent relating hereto or thereto, of the Administrative Agent and its Affiliates in
connection with its or their syndication efforts with respect to this Agreement and of the Administrative Agent and, after the occurrence of an Event of Default, each of the Lenders in connection with the enforcement of this Agreement and the other
Credit Documents and the documents and instruments referred to herein and therein or in connection with any refinancing or restructuring of the credit arrangements provided under this Agreement in the nature of a “work-out” or pursuant to
any insolvency or bankruptcy proceedings (including, in each case without limitation, the reasonable fees and disbursements of counsel and consultants for the Administrative Agent and, after the occurrence of an Event of Default, counsel for each of
the Lenders); (ii) pay and hold the Administrative Agent and each of the Lenders harmless from and against any and all present and future stamp, excise and other similar documentary taxes with respect to the foregoing matters and save the
Administrative Agent and each of the Lenders harmless from and against any and all liabilities with respect to or resulting from any delay or omission (other than to the extent attributable to the Administrative Agent or such Lender) to pay such
taxes; and (iii) indemnify the Administrative Agent and each Lender, and each of their respective officers, directors, employees, representatives, agents, affiliates, trustees and investment advisors (each, an “Indemnified Person”)
from and hold each of them harmless against any and all liabilities, obligations (including removal or remedial actions), losses, damages, penalties, claims, actions, judgments, suits, costs, expenses and disbursements (including reasonable
attorneys’ and consultants’ fees and disbursements) incurred by, imposed on or assessed against any of them as a result of, or arising out of, or in any way related to, or by reason of, (x) any investigation, litigation or other
proceeding (whether or not the Administrative Agent or any Lender is a party thereto and whether or not such investigation, litigation or other proceeding is brought by or on behalf of any Credit Party) related to the entering into and/or
performance of this Agreement or any other Credit Document or the use of the proceeds of any Loans hereunder or the consummation of the Transactions or any other transactions contemplated herein or in any other Credit Document or the syndication of
this Agreement or the exercise of any of their rights or remedies provided herein or in the other Credit Documents, or (y) the actual or alleged presence of Hazardous Materials in the air, surface water or groundwater or on the surface or
subsurface of any Real Property at any time owned, leased, used by or operated by Holdings or any of its Subsidiaries or any of their respective predecessors (but with respect to formerly owned, leased, used or operated Real Properties, only to the
extent arising from the acts or omissions of Holdings or any of its Subsidiaries), the generation, storage, transportation, handling or disposal 

  
 115









 
of Hazardous Materials by Holdings or any of its Subsidiaries or any of their respective predecessors at any location, whether or not owned, leased, used by or operated by Holdings or any of its
Subsidiaries, the non-compliance by Holdings or any of its Subsidiaries with any Environmental Law (including applicable permits thereunder) applicable to any Real Property, or any claim under any Environmental Law asserted against Holdings, any of
its Subsidiaries or any of their respective predecessors or any Real Property at any time owned, leased, used by or operated by such entity, including, in each case, without limitation, the reasonable fees and disbursements of counsel and other
consultants incurred in connection with any such investigation, litigation or other proceeding (but excluding any losses, liabilities, claims, damages or expenses to the extent incurred by reason of the gross negligence or willful misconduct of the
Indemnified Person to be indemnified (as determined by a court of competent jurisdiction in a final and non-appealable decision)). To the extent that the undertaking to indemnify, pay or hold harmless the Administrative Agent or any Lender set forth
in the preceding sentence may be unenforceable because it is violative of any law or public policy, Holdings shall make the maximum contribution to the payment and satisfaction of each of the indemnified liabilities which is permissible under
applicable law. 
 (b) To the full extent permitted by applicable law, each of Holdings and the Borrower shall not assert, and
hereby waives, any claim against any Indemnified Person, on any theory of liability, for special, indirect, consequential or incidental damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this
Agreement, any other Credit Document, any other agreement or instrument contemplated hereby or thereby, the transactions contemplated hereby or thereby or any Loan or the use of the proceeds thereof. No Indemnified Person shall be liable for any
damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Credit
Documents or the transactions contemplated hereby or thereby, except to the extent the liability of such Indemnified Person results from such Indemnified Person’s gross negligence or willful misconduct (as determined by a court of competent
jurisdiction in a final and non-appealable decision). 
 11.02. Right of Setoff. In addition to any rights now or
hereafter granted under applicable law or otherwise, and not by way of limitation of any such rights, upon the occurrence and during the continuance of an Event of Default, the Administrative Agent and each Lender is hereby authorized at any time or
from time to time, without presentment, demand, protest or other notice of any kind to any Credit Party or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and apply any and all deposits (general or
special) and any other Indebtedness at any time held or owing by the Administrative Agent or such Lender or any Affiliate, branch or agency thereof (including, without limitation, by branches and agencies of the Administrative Agent or such Lender
or Affiliate wherever located) to or for the credit or the account of Holdings or any of its Subsidiaries against and on account of the Obligations and liabilities of the Credit Parties to the Administrative Agent or such Lender under this Agreement
or under any of the other Credit Documents, including, without limitation, all interests in Obligations purchased by such Lender pursuant to Section 11.04(b), and all other claims of any nature or description arising out of or connected
with this Agreement or any other Credit Document, irrespective of whether or not the Administrative Agent or such Lender shall have made any demand hereunder and although said Obligations, liabilities or claims, or any of them, shall be contingent
or unmatured. 

  
 116









 11.03. Notices. Except as otherwise expressly provided herein, all notices and other
communications provided for hereunder shall be in writing (including telegraphic, telecopier or cable communication) and mailed, telegraphed, telecopied, cabled or delivered: if to the Borrower, to Endeavour Energy UK Limited, 114 St. Martin’s
Lane, London WC2N 4BE, England, Attention: J. Michael Kirksey, Facsimile: 44 20 7451 2351, with a copy to Endeavour International Corporation, 811 Main Street, Suite 2100, Houston, Texas 77002, Attention: J. Michael Kirksey, Facsimile:
(713) 307-8794, if to any Credit Party (other than the Borrower), c/o Endeavour International Corporation, 1001 Fannin, Suite 1600, Houston, Texas 77002, Attention: J. Michael Kirksey, Facsimile: (713) 307-8794, if to any Lender, at its
address specified on Schedule 11.03 hereto; and if to the Administrative Agent, at the Notice Office; or, as to any Credit Party or the Administrative Agent, at such other address as shall be designated by such party in a written notice to the other
parties hereto and, as to each Lender, at such other address as shall be designated by such Lender in a written notice to the Borrower and the Administrative Agent. All such notices and communications shall, when mailed, telegraphed, telecopied, or
cabled or sent by overnight courier, be effective when deposited in the mails, delivered to the telegraph company, cable company or overnight courier, as the case may be, or sent by telecopier, except that notices and communications to the
Administrative Agent, and the Borrower shall not be effective until received by the Administrative Agent or the Borrower, as the case may be. 
 11.04. Benefit of Agreement; Assignments; Participations. (a) This Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of
the parties hereto; provided, however, that neither Holdings nor the Borrower may assign or transfer any of its rights, obligations or interest hereunder without the prior written consent of the Lenders and, provided
further, that, although any Lender may transfer, assign or grant participations in its rights hereunder, such Lender shall remain a “Lender” for all purposes hereunder (and may not transfer or assign all or any portion of its
Commitment or any related Obligations hereunder except as provided in Sections 2.09 and 11.04(b)) and the transferee, assignee or participant, as the case may be, shall not constitute a “Lender” hereunder and, provided
further, that no Lender shall transfer or grant any participation under which the participant shall have rights to approve any amendment to or waiver of this Agreement or any other Credit Document except to the extent such amendment or waiver
would (i) extend the final scheduled maturity of any Loan or Note in which such participant is participating, or reduce the rate or extend the time of payment of interest or Fees thereon (except in connection with a waiver of applicability of
any post-default increase in interest rates) or reduce the principal amount thereof, or increase the amount of the participant’s participation over the amount thereof then in effect (it being understood that a waiver of any Default or Event of
Default or of a mandatory reduction in the Total Commitment shall not constitute a change in the terms of such participation, and that an increase in any Commitment (or the available portion thereof) or Loan shall be permitted without the consent of
any participant if the participant’s participation is not increased as a result thereof), (ii) consent to the assignment or transfer by Holdings or the Borrower of any of its rights and obligations under this Agreement or
(iii) release all or substantially all of the Collateral under all of the Security Documents (except as expressly provided in the Credit Documents) supporting the Loans hereunder in which such participant is 

  
 117









 
participating. In the case of any such participation, the participant shall not have any rights under this Agreement or any of the other Credit Documents (the participant’s rights against
such Lender in respect of such participation to be those set forth in the agreement executed by such Lender in favor of the participant relating thereto) and all amounts payable by the Borrower hereunder shall be determined as if such Lender had not
sold such participation. 
 (b) Notwithstanding the foregoing, any Lender (or any Lender together with one or more other
Lenders) may (x) assign all or a portion of its Commitments and related outstanding Obligations (or, if the Commitments have terminated, outstanding Obligations) hereunder to (i) (A) its parent company and/or any affiliate of such
Lender which is at least 50% owned by such Lender or its parent company or (B) to one or more other Lenders or any affiliate of any such other Lender which is at least 50% owned by such other Lender or its parent company (provided that
any fund that invests in loans and is managed or advised by the same investment advisor of another fund which is a Lender (or by an Affiliate of such investment advisor) shall be treated as an affiliate of such other Lender for the purposes of this
sub-clause (x)(i)(B)), or (ii) in the case of any Lender that is a fund that invests in loans, any other fund that invests in loans and is managed or advised by the same investment advisor of any Lender or by an Affiliate of such investment
advisor; provided that, in no event shall any assignment of Commitments or Loans pursuant to this clause (x) be made to Holdings, the Borrower or any of their respective Subsidiaries or Affiliates, or (y) assign all, or if less than
all, a portion equal to at least $5,000,000 in the aggregate for the assigning Lender or assigning Lenders, of such Commitment and related outstanding Obligations (or, if the Commitment has terminated, outstanding Obligations) hereunder to one or
more Eligible Transferees (treating any fund that invests in loans and any other fund that invests in loans and is managed or advised by the same investment advisor of such fund or by an Affiliate of such investment advisor as a single Eligible
Transferee), each of which assignees shall become a party to this Agreement as a Lender by execution of an Assignment and Assumption Agreement, provided that (i) at such time, Schedule 1.01(b) shall be deemed modified to reflect the
Commitments and/or outstanding Loans, as the case may be, of such new Lender and of the existing Lenders, (ii) upon the surrender of the relevant Notes by the assigning Lender (or, upon such assigning Lender’s indemnifying the Borrower for
any lost Note pursuant to a customary indemnification agreement) new Notes will be issued, at the Borrower’s expense, to such new Lender and to the assigning Lender, such new Notes to be in conformity with the requirements of
Section 2.05 (with appropriate modifications) to the extent needed to reflect the revised Commitments and/or outstanding Loans, as the case may be, (iii) the consent of the Administrative Agent and after the Syndication Date, so
long as no Default or Event of Default then exists, the Borrower, shall be required in connection with any such assignment pursuant to clause (y) above (such consent, in any case, not to be unreasonably withheld, delayed or conditioned);
provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within 5 Business Days after having received notice thereof, (iv) the
Administrative Agent shall receive at the time of each such assignment, from the assigning or assignee Lender, the payment of a non-refundable assignment fee of $3,500 and (v) no such transfer or assignment will be effective until recorded by
the Administrative Agent on the Register pursuant to Section 11.15. To the extent of any assignment pursuant to this Section 11.04(b), the assigning Lender shall be relieved of its obligations hereunder with respect to its
assigned Commitment and outstanding Loans. To the extent that an assignment of all or any portion of a Lender’s Commitment and related outstanding Obligations pursuant to Section 2.09 


  
 118









 
or this Section 11.04(b), would, at the time of such assignment, result in increased costs under Section 2.10 from those being charged by the respective assigning Lender
prior to such assignment, then the Borrower shall not be obligated to pay such increased costs (although the Borrower, in accordance with and pursuant to the other provisions of this Agreement, shall be obligated to pay any other increased costs of
the type described above resulting from changes after the date of the respective assignment). 
 (c) Nothing in this Agreement
shall prevent or prohibit any Lender from pledging its Loans and Notes hereunder to a Federal Reserve Bank in support of borrowings made by such Lender from such Federal Reserve Bank and, with prior notification to the Administrative Agent (but
without the consent of the Administrative Agent or the Borrower), any Lender which is a fund may pledge all or any portion of its Loans and Notes to its trustee or to a collateral agent or financial institution providing credit or credit support to
such Lender in support of its obligations to such trustee, such collateral agent or such financial institution, as the case may be. No pledge pursuant to this clause (c) shall release the transferor Lender from any of its obligations hereunder.

 (d) Any Lender which assigns all of its Commitments and/or Loans hereunder in accordance with Section 11.04(b)
shall cease to constitute a “Lender” hereunder, except with respect to indemnification provisions under this Agreement (including, without limitation, Sections 4.04, 10.06, 11.01 and 11.06), which shall survive
as to such assigning Lender. 
 11.05. No Waiver; Remedies Cumulative. No failure or delay on the part of the
Administrative Agent, the Collateral Agent or any Lender in exercising any right, power or privilege hereunder or under any other Credit Document and no course of dealing between the Borrower or any other Credit Party and the Administrative Agent,
the Collateral Agent or any Lender shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Credit Document preclude any other or further exercise thereof or the
exercise of any other right, power or privilege hereunder or thereunder. The rights, powers and remedies herein or in any other Credit Document expressly provided are cumulative and not exclusive of any rights, powers or remedies which the
Administrative Agent, the Collateral Agent or any Lender would otherwise have. No notice to or demand on any Credit Party in any case shall entitle any Credit Party to any other or further notice or demand in similar or other circumstances or
constitute a waiver of the rights of the Administrative Agent, the Collateral Agent or any Lender to any other or further action in any circumstances without notice or demand. 
 11.06. Payments Pro Rata. (a) Except as otherwise provided in this Agreement (including in Section 8.04), the Administrative Agent agrees that promptly after its receipt of each payment
from or on behalf of the Borrower in respect of any Obligations hereunder, the Administrative Agent shall distribute such payment to the Lenders entitled thereto (other than any Lender that has consented in writing to waive its pro
rata share of any such payment) pro rata based upon their respective shares, if any, of the Obligations with respect to which such payment was received. 

  
 119









 (b) Each of the Lenders agrees that, if it should receive any amount hereunder (whether by
voluntary payment, by realization upon security, by the exercise of the right of setoff or banker’s lien, by counterclaim or cross action, by the enforcement of any right under the Credit Documents, or otherwise), which is applicable to the
payment of the principal of, or interest on, the Loans, of a sum which with respect to the related sum or sums received by other Lenders is in a greater proportion than the total of such Obligation then owed and due to such Lender bears to the total
of such Obligation then owed and due to all of the Lenders immediately prior to such receipt, then such Lender receiving such excess payment shall purchase for cash without recourse or warranty from the other Lenders an interest in the Obligations
of the respective Credit Party to such Lenders in such amount as shall result in a proportional participation by all the Lenders in such amount; provided that if all or any portion of such excess amount is thereafter recovered from such
Lenders, such purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest. 

(c) Notwithstanding anything to the contrary contained herein, the provisions of the preceding Sections 11.06(a) and
(b) shall be subject to the express provisions of this Agreement which require, or permit, differing payments to be made to Non-Defaulting Lenders as opposed to Defaulting Lenders. 

11.07. Calculations; Computations. (a) All accounting determinations under this Agreement and all financial statements to be
furnished to the Lenders pursuant hereto shall be made and prepared in accordance with GAAP consistently applied throughout the periods involved (except as set forth in the notes thereto or as otherwise disclosed in writing by Holdings to the
Lenders); provided that, to the extent expressly provided herein, certain calculations shall be made on a pro forma basis. Holdings, the Borrower and the Administrative Agent, on behalf of the Lenders, agree that in the event of any material
change in GAAP (any such change, for the purpose of this Section 11.07, an “Accounting Change”) that occurs after the date of this Agreement, then following the written request of either the Borrower or the
Administrative Agent, the Borrower and the Administrative Agent shall enter into good faith negotiations in order to amend such provisions of this Agreement so as to equitably reflect any such Accounting Change with the desired result that the
criteria for evaluating the financial condition of Holdings and its Subsidiaries shall be the same after such Accounting Change as if such Accounting Change had not been made, and until such time as such an amendment shall have been executed and
delivered by Holdings, the Borrower and Required Lenders, (a) all financial ratios, standards and terms in this Agreement shall be calculated and/or construed as if such Accounting Change had not been made, and (b) the Borrower shall
prepare footnotes to each certificate and the financial statements required to be delivered pursuant to Sections 7.01(b), (c), and (g) hereunder that show the differences between the financial statements delivered (which
reflect such Accounting Change) and the basis for calculating compliance with incurrence based financial covenants (without reflecting such Accounting Change). 
 (b) All computations of interest, Commitment Commission and other Fees hereunder shall be made on the basis of a year of 360 days for the actual number of days (including the first day but excluding the
last day) occurring in the period for which such interest, Commitment Commission or Fees are payable. 

  
 120









 (c) For purposes of any computation determining compliance with any incurrence or
expenditure tests set forth in Sections 1 and/or 8 or with Dollar-based basket levels appearing in any definitions contained in Section 1.01, any amounts so incurred, expended or utilized (to the extent incurred, expended or
utilized in a currency other than Dollars) shall be converted into Dollars on the basis of the Exchange Rates as in effect on the date of such incurrence, expenditure or utilization under any provision of any such Section or definition that has an
aggregate Dollar limitation provided for therein (and to the extent the respective incurrence, expenditure or utilization test regulates the aggregate amount outstanding at any time and it is expressed in terms of Dollars, all outstanding amounts
originally incurred or spent in currencies other than Dollars shall be converted into Dollars on the basis of the Exchange Rates as in effect on the date of any new incurrence, expenditure or utilization made under any provision of any such Section
that regulates the Dollar amount outstanding at any time). 
 11.08. GOVERNING LAW; SUBMISSION TO JURISDICTION; VENUE; WAIVER
OF JURY TRIAL. (a) THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL, EXCEPT AS OTHERWISE PROVIDED IN THE RELEVANT SECURITY DOCUMENT BE CONSTRUED IN ACCORDANCE WITH
AND BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK (WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES). ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW
YORK OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF NEW YORK, IN EACH CASE WHICH ARE LOCATED IN THE COUNTY OF NEW YORK (EXCEPT THAT, (X) IN THE CASE OF ANY SECURITY DOCUMENT, PROCEEDINGS MAY ALSO BE BROUGHT BY THE ADMINISTRATIVE AGENT OR
COLLATERAL AGENT IN THE STATE IN WHICH THE RESPECTIVE COLLATERAL IS LOCATED OR ANY OTHER RELEVANT JURISDICTION AND (Y) IN THE CASE OF ANY BANKRUPTCY, INSOLVENCY OR SIMILAR PROCEEDINGS WITH RESPECT TO ANY CREDIT PARTY, ACTIONS OR PROCEEDINGS
RELATED TO THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS MAY BE BROUGHT IN SUCH COURT HOLDING SUCH BANKRUPTCY, INSOLVENCY OR SIMILAR PROCEEDINGS) AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT, EACH OF HOLDINGS AND THE
BORROWER HEREBY IRREVOCABLY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE EXCLUSIVE JURISDICTION OF THE AFORESAID COURTS. EACH OF HOLDINGS AND THE BORROWER HEREBY FURTHER IRREVOCABLY WAIVES ANY CLAIM THAT ANY
SUCH COURTS LACK PERSONAL JURISDICTION OVER HOLDINGS OR THE BORROWER, AND AGREES NOT TO PLEAD OR CLAIM, IN ANY LEGAL ACTION PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT BROUGHT IN ANY OF THE AFOREMENTIONED COURTS, THAT SUCH
COURTS LACK PERSONAL JURISDICTION OVER HOLDINGS OR THE BORROWER. EACH OF HOLDINGS AND THE BORROWER FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT 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 HOLDINGS OR THE BORROWER AT ITS ADDRESS SET FORTH IN SECTION 11.03 AND, IN THE CASE OF SERVICE OF PROCESS TO THE BORROWER, AS PROVIDED IN SECTION 11.18, IN EACH CASE
SUCH SERVICE TO BECOME EFFECTIVE 30 DAYS AFTER SUCH MAILING. EACH OF HOLDINGS AND THE BORROWER HEREBY IRREVOCABLY 

  
 121









 
WAIVES ANY OBJECTION TO SUCH SERVICE OF PROCESS AND FURTHER IRREVOCABLY WAIVES AND AGREES NOT TO PLEAD OR CLAIM IN ANY ACTION OR PROCEEDING COMMENCED HEREUNDER OR UNDER ANY OTHER CREDIT DOCUMENT
THAT SERVICE OF PROCESS WAS IN ANY WAY INVALID OR INEFFECTIVE. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE ADMINISTRATIVE AGENT, ANY LENDER OR THE HOLDER OF ANY NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL
PROCEEDINGS OR OTHERWISE PROCEED AGAINST HOLDINGS OR THE BORROWER IN ANY OTHER JURISDICTION. 
 (b) EACH OF HOLDINGS AND THE
BORROWER HEREBY IRREVOCABLY WAIVES (TO THE FULLEST EXTENT PERMITTED BY LAW) ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY OF THE AFORESAID ACTIONS OR PROCEEDINGS ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR
ANY OTHER CREDIT DOCUMENT BROUGHT IN THE COURTS REFERRED TO IN CLAUSE (a) ABOVE AND HEREBY FURTHER IRREVOCABLY WAIVES AND AGREES NOT TO PLEAD OR CLAIM IN ANY SUCH COURT THAT ANY SUCH ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN
BROUGHT IN AN INCONVENIENT FORUM. 
 (c) EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY
JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. 
 11.09. Counterparts. This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which when so executed and delivered shall be
an original, but all of which shall together constitute one and the same instrument. A set of counterparts executed by all the parties hereto shall be lodged with the Borrower and the Administrative Agent. Delivery of an executed counterpart hereof
by facsimile or electronic transmission shall be as effective as delivery of any original executed counterpart hereof. 
 11.10.
Effectiveness. This Agreement shall become effective on the date (the “Effective Date”) on which (a) Holdings, the Borrower, the Administrative Agent and each of the Lenders shall have signed a copy of this Agreement
(whether the same or different copies) and shall have delivered the same to the Administrative Agent at the Notice Office or, in the case of the Lenders, shall have given to the Administrative Agent telephonic (confirmed in writing), written telex
or facsimile transmission notice (actually received) that the same has been signed and mailed to it and (b) the conditions contained in Section 5.01 have been met to the reasonable satisfaction of the Administrative Agent (or duly
waived by the Required Lenders). Unless the Administrative Agent has received actual notice from any Lender that the conditions described in clause (b) of the preceding sentence have not been met to its satisfaction, upon the satisfaction of
the condition described in clause (a) of the immediately preceding sentence and upon the Administrative Agent’s good faith determination that the conditions in clause (b) of the immediately preceding sentence have been met, then the
Effective Date shall be deemed to have 

  
 122









 
occurred, regardless of any subsequent determination that one or more of the conditions thereto had not been met (although the occurrence of the Effective Date shall not release the Borrower from
any liability for failure to satisfy one or more of the applicable conditions contained in Section 5.01, other than any condition that must be satisfied to the Administrative Agent’s satisfaction or other subjective standard of
similar effect). The Administrative Agent will give the Borrower and each Lender prompt written notice of the occurrence of the Effective Date. 
 11.11. Headings Descriptive. The headings of the several sections and subsections of this Agreement are inserted for convenience only and shall not in any way affect the meaning or construction of
any provision of this Agreement. 
 11.12. Amendment or Waiver; etc. (a) Neither this Agreement nor any other Credit
Document nor any terms hereof or thereof may be changed, waived, discharged or terminated unless such change, waiver, discharge or termination is in writing signed by the respective Credit Parties party hereto or thereto and the Required Lenders
(although additional parties may be added to (and schedules and annexes may be modified to reflect such additions), and Subsidiaries of the Borrower may be released from, the Security Documents in accordance with the provisions hereof and thereof
without the consent of the other Credit Parties party thereto or the Required Lenders), provided that no such change, waiver, discharge or termination shall, without the consent of each Lender (with Obligations being directly affected in the
case of following clause (a)), (i) extend the final scheduled maturity of any Loan or Note, or reduce the rate or extend the time of payment of interest or Fees thereon (except in connection with the waiver of applicability of any post-default
increase in interest rates), or reduce (or forgive) the principal amount thereof, (ii) release all or substantially all of the Collateral (except as expressly provided in the Credit Documents) under all the Security Documents, (iii) amend,
modify or waive any provision of this Section 11.12(a) (except for technical amendments with respect to additional extensions of credit pursuant to this Agreement which afford the protections to such additional extensions of credit of
the type provided to the Commitments and the Loans on the Effective Date), (iv) release the Holdings Guaranty or release all or substantially all of the aggregate value of the Subsidiaries Guaranties, (v) reduce the “majority”
voting threshold specified in the definition of Required Lenders or the “supermajority” voting threshold specified in the definition of Supermajority Lenders (it being understood that, with the consent of the Required Lenders, additional
extensions of credit pursuant to this Agreement may be included in the determination of the Required Lenders and the Supermajority Lenders on substantially the same basis as the extensions of Commitments and/or Loans are included on the Effective
Date) or (vi) consent to the assignment or transfer by Holdings or the Borrower of any of its rights and obligations under this Agreement; provided further, that no such change, waiver, discharge or termination shall
(1) increase the Commitment of any Lender over the amount thereof then in effect without the consent of such Lender (it being understood that waivers or modifications of conditions precedent, covenants, Defaults or Events of Default or of a
mandatory reduction in the Total Commitment shall not constitute an increase of the Commitment of any Lender, and that an increase in the available portion of the Commitment of any Lender shall not constitute an increase of the Commitment of such
Lender), (2) without the consent of the Administrative Agent, amend, modify or waive any provision of Section 10 or any other provision of this Agreement or any other Credit Document as same relates to the rights or obligations of
the Administrative Agent, (3) without the consent of the Collateral Agent, amend, modify or waive any provision relating to the rights or obligations of the Collateral Agent or (4) without the


  
 123









 
consent of the Supermajority Lenders, amend, modify or waive the definition of Permitted Debt, clause (iii) of the proviso contained in the first sentence of Section 2.11(a),
Section 8.04, Section 8A(b) or Section 8A(c), in each case under this clause (4) in a manner such that such definition, proviso, or Section, as the case may be, would be less restrictive to Holdings and its
Subsidiaries. 
 (b) If, in connection with any proposed change, waiver, discharge or termination of or to any of the provisions
of this Agreement as contemplated by clauses (i) through (vi), inclusive, of the first proviso to Section 11.12(a), the consent of the Required Lenders is obtained but the consent of one or more of such other Lenders whose consent
is required is not obtained, then the Borrower shall have the right, so long as all non-consenting Lenders whose individual consent is required are treated as described below, to replace each such non-consenting Lender or Lenders with one or more
Replacement Lenders pursuant to Section 2.09 so long as at the time of such replacement, each such Replacement Lender consents to the proposed change, waiver, discharge or termination, provided further, that the Borrower
shall not have the right to replace a Lender or repay its Loans solely as a result of the exercise of such Lender’s rights (and the withholding of any required consent by such Lender) pursuant to the second proviso to
Section 11.12(a). 
 (c) Anything herein to the contrary notwithstanding, in the event that a Lender becomes a
Defaulting Lender, then such Lender will not be entitled to vote in respect of amendments, waivers and consents hereunder and the Commitment and the outstanding Loans of such Lender will not be taken into account in determining whether the Required
Lenders, the Supermajority Lenders or all of the Lenders, as required, have approved any such amendment, waiver or consent (and the definition of “Required Lenders” and “Supermajority Lenders” will automatically be deemed
modified accordingly for the duration of such period); provided that any such amendment or waiver that would increase or extend the term of the Commitment of such Defaulting Lender, extend the date fixed for the payment of principal or
interest owing to such Defaulting Lender hereunder, reduce the principal amount of any obligation owing to such Defaulting Lender, reduce the amount of or the rate or amount of interest on any amount owing to such Defaulting Lender or of any Fee
payable to such Defaulting Lender hereunder, or alter the terms of this proviso, will require the consent of such Defaulting Lender. 
 (d) Further, notwithstanding anything to the contrary contained in this Section 11.12, if following the Effective Date, the Administrative Agent and any Credit Party shall have jointly
identified an obvious error or any error or omission of a technical or immaterial nature, in each case, in any provision of the Credit Documents, then the Administrative Agent and the Credit Parties shall be permitted to amend such provision and
such amendment shall become effective without any further action or consent of any other party to any Credit Documents if the same is not objected to in writing by the Required Lenders within five Business Days following receipt of notice thereof.

 11.13. Survival. All indemnities set forth herein including, without limitation, in Sections 2.10, 4.04,
10.06 and 11.01 shall survive the execution, delivery and termination of this Agreement and the Notes and the making and repayment of the Obligations. 

  
 124









 11.14. Domicile of Loans. Each Lender may transfer and carry its Loans at, to or for
the account of any office, Subsidiary or Affiliate of such Lender. Notwithstanding anything to the contrary contained herein, to the extent that a transfer of Loans pursuant to this Section 11.14 would, at the time of such transfer,
result in increased costs under Section 2.10 or 4.04, from those being charged by the respective Lender prior to such transfer, then the Borrower shall not be obligated to pay such increased costs (although the Borrower shall be
obligated to pay any other increased costs of the type described above resulting from changes after the date of the respective transfer to the extent otherwise required under any such Section). 

11.15. Register. The Borrower hereby designates the Administrative Agent to serve as its agent, solely for purposes of this
Section 11.15, to maintain a register (the “Register”) on which it will record the Commitments from time to time of each of the Lenders (including any increases to the principal amounts thereof as a result of payment of
PIK Interest), the Loans made by each of the Lenders and each repayment in respect of the principal amount of the Loans of each Lender. Failure to make any such recordation, or any error in such recordation, shall not affect the Borrower’s
obligations in respect of such Loans. With respect to any Lender, the transfer of the Commitment of such Lender and the rights to the principal of, and interest on, any Loan made pursuant to such Commitment shall not be effective until such transfer
is recorded on the Register maintained by the Administrative Agent with respect to ownership of such Commitment and Loans and prior to such recordation all amounts owing to the transferor with respect to such Commitment and Loans shall remain owing
to the transferor. The registration of assignment or transfer of all or part of any Commitments and Loans shall be recorded by the Administrative Agent on the Register only upon the acceptance by the Administrative Agent of a properly executed and
delivered Assignment and Assumption Agreement pursuant to Section 11.04(b). Coincident with the delivery of such an Assignment and Assumption Agreement to the Administrative Agent for acceptance and registration of assignment or transfer
of all or part of a Loan, or as soon thereafter as practicable, the assigning or transferor Lender shall surrender the Note evidencing such Loan, and thereupon one or more new Notes in the same aggregate principal amount shall be issued to the
assigning or transferor Lender and/or the new Lender. The Borrower agrees to indemnify the Administrative Agent from and against any and all losses, claims, damages and liabilities of whatsoever nature which may be imposed on, asserted against or
incurred by the Administrative Agent in performing its duties under this Section 11.15. 
 11.16.
Confidentiality. (a) Subject to the provisions of clause (b) of this Section 11.16, each Lender agrees that it will not disclose without the prior consent of the Borrower (other than to its employees, auditors, advisors
or counsel or to another Lender if such Lender or such Lender’s holding or parent company in its sole discretion determines that any such party should have access to such information, provided such Persons shall be subject to the provisions of
this Section 11.16 to the same extent as such Lender) any information with respect to Holdings or any of its Subsidiaries which is now or in the future furnished pursuant to this Agreement or any other Credit Document, provided
that any Lender may disclose any such information (i) as has become generally available to the public other than by virtue of a breach of this Section 11.16(a) by the respective Lender, (ii) as may be required or appropriate in
any report, statement or testimony submitted to any municipal, state or Federal regulatory body having or claiming to have jurisdiction over such Lender or to the Federal Reserve Board or the Federal Deposit Insurance Corporation or similar
organizations (whether in the United States or elsewhere) or their successors, (iii) as may be required or appropriate in respect to any summons or subpoena or in connection with any litigation, (iv) in order to comply with any law, order,


  
 125









 
regulation or ruling applicable to such Lender or to comply with a request by a Governmental Authority, (v) to the Administrative Agent or the Collateral Agent, (vi) to any direct or
indirect contractual counterparty in any swap, hedge or similar agreement (or to any such contractual counterparty’s professional advisor), so long as such contractual counterparty (or such professional advisor) agrees to be bound by the
provisions of this Section 11.166, (vii) in connection with the enforcement of remedies pursuant to this Agreement and the other Credit Documents, (viii) to any prospective or actual transferee, pledgee or participant in
connection with any contemplated transfer, pledge or participation of any of the Notes or Commitments or any interest therein by such Lender; provided that such prospective transferee, pledgee or participant agrees to be bound by the
confidentiality provisions contained in this Section 11.16, (ix) to (i) any bank or financial institution and (ii) S&P, Moody’s, Fitch Ratings and/or other ratings agencies, as such Lender deems necessary or
appropriate in connection with such Lender’s obtaining financing; provided, however, that such financial institution or ratings agency shall be informed of the confidentiality of such information and (x) to its investors or
potential investors as such Lender reasonably deems necessary or appropriate; provided, however, that such investors or potential investors shall be informed of the confidentiality of such information. 

(b) Each of Holdings and the Borrower hereby acknowledges and agrees that each Lender may share with any of its Affiliates, and such
Affiliates may share with such Lender, any information related to Holdings or any of its Subsidiaries (including, without limitation, any non-public customer information regarding the creditworthiness of Holdings and its Subsidiaries), provided such
Persons shall be subject to the provisions of this Section 11.16 to the same extent as such Lender. 
 (c)
Notwithstanding anything to the contrary contained in this Section, each of Holdings and the Borrower hereby agrees that the Administrative Agent and its Affiliates may publicize its services in connection with this Agreement and the other Credit
Documents and the transactions contemplated herein and therein, including, without limitation, through granting interviews with and providing information to the financial press and other media and by publicizing such services on its web-site or
other electronic medium; provided, however, that the Administrative Agent and its Affiliates shall not publicize as contemplated above in this clause (c) until the earlier to occur of (i) the 5th day following the Effective
Date and (ii) such date as when Holdings shall have publicly announced the consummation of those of the Transactions to be consummated on the Effective Date. In addition, each of Holdings and the Borrower hereby authorizes the Administrative
Agent to place a customary “tombstone” advertisement regarding this Agreement and the transactions contemplated herein related hereto in publications of its choice at the Borrower’s expense. 

11.17. Patriot Act. Each Lender subject to the USA PATRIOT ACT (Title 111 of Pub. L. 107-56 (signed into law October 26,
2001)) (the “Patriot Act”) hereby notifies Holdings and the Borrower that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies Holdings, the Borrower and the other
Credit Parties and other information that will allow such Lender to identify Holdings, the Borrower and the other Credit Parties in accordance with the Patriot Act. 

  
 126









 11.18. Process Agent. (a) Each Credit Party hereby irrevocably and
unconditionally appoints CT Corporation with an office on the date hereof at 111 Eighth Avenue, New York, New York 10011, and its successors hereunder (the “Process Agent”), as its agent to receive on behalf of such Credit Party and
its property all writs, claims, process, and summonses in any action or proceeding brought against such Credit Party in the State of New York. Such service may be made by mailing or delivering a copy of such process to any Credit Party in care of
the Process Agent at the address specified above for the Process Agent, and such Credit Party irrevocably authorizes and directs the Process Agent to accept such service on its behalf. Failure by the Process Agent to give notice to the applicable
Credit Party, or failure of the applicable Credit Party, to receive notice of such service of process shall not impair or affect the validity of such service on the Process Agent or any such Credit Party, or of any judgment based thereon. Each
Credit Party party hereto covenants and agrees that it shall take any and all reasonable action, including the execution and filing of any and all documents that may be necessary to continue the designation of the Process Agent above in full force
and effect, and to cause the Process Agent to act as such. Each Credit Party party hereto further covenants and agrees to maintain at all times an agent with offices in New York City to act as its Process Agent. Nothing herein shall in any way be
deemed to limit the ability to serve any such writs, process or summonses in any other manner permitted by applicable law. 

(b) Each Credit Party that is not incorporated in England and Wales and that has executed, or will on the Effective Date execute, any
Credit Document governed by the law of England and Wales irrevocably and unconditionally appoints the Borrower, with an office on the date hereof at 114 St. Martin’s Lane, London WC2N 4BE, England, and its successors hereunder (the “UK
Process Agent”), as its agent to receive on behalf of such Credit Party and its property all writs, claims, process, and summonses in any action or proceeding brought against such Credit Party in England and Wales. Such service may be made
by mailing or delivering a copy of such process to any Credit Party in care of the UK. Process Agent at the address specified above for the UK Process Agent, and such Credit Party irrevocably authorizes and directs the UK Process Agent to accept
such service on its behalf. Failure by the UK Process Agent to give notice to such Credit Party, or failure of such Credit Party, to receive notice of such service of process shall not impair or affect the validity of such service on the UK Process
Agent or any such Credit Party, or of any judgment based thereon. Each such Credit Party covenants and agrees that it shall take any and all reasonable action, including the execution and filing of any and all documents that may be necessary to
continue the designation of the UK Process Agent above in full force and effect, and to cause the UK Process Agent to act as such. Each such Credit Party further covenants and agrees to maintain at all times an agent with offices in England to act
as its UK Process Agent. Nothing herein shall in any way be deemed to limit the ability to serve any such writs, process or summonses in any other manner permitted by applicable law. If any person appointed as an agent for service in England and
Wales is unable for any reason to act as agent for service of process, Holdings (on behalf of all such Credit Parties) shall immediately (and in any event within five days of such event taking place) appoint another agent on terms acceptable to the
Administrative Agent. In the event that Holdings fails to appoint such agent on terms acceptable to the Administrative Agent, the Administrative Agent shall have the right to appoint an agent for service of process. 

  
 127









 11.19. Judgment Currency. If, for the purposes of obtaining judgment in any court, it
is necessary to convert a sum due hereunder or any other Credit Document in one currency into another currency, the rate of exchange used shall be that at which in accordance with normal banking procedures the Administrative Agent could purchase the
first currency with 
 such other currency on the Business Day preceding that on which final judgment is given. The obligation of the Credit
Parties in respect of any such sum due from it to the Administrative Agent or the Lenders hereunder or under the other Credit Documents shall, notwithstanding any judgment in a currency (the “Judgment Currency”) other than that in
which such sum is denominated in accordance with the applicable provisions of this Agreement (the “Agreement Currency”), be discharged only to the extent that on the Business Day following receipt by the Administrative Agent of any
sum adjudged to be so due in the Judgment Currency, the Administrative Agent may in accordance with normal banking procedures purchase the Agreement Currency with the Judgment Currency. If the amount of the Agreement Currency so purchased is less
than the sum originally due to the Administrative Agent from the Credit Parties in the Agreement Currency, the Credit Parties agree, jointly and severally, as a separate obligation and notwithstanding any such judgment, to indemnify the
Administrative Agent or the Person to whom such obligation was owing against such loss. 
 11.20. Maximum Lawful Rate.
Notwithstanding anything to the contrary contained in any Credit Document, the interest paid or agreed to be paid under the Credit Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable law (the “Maximum
Rate”). If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the principal of the Loans, or, if it exceeds such unpaid principal, refunded to
the Borrower. In determining whether the interest contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to the extent permitted by applicable law, (a) characterize any payment
that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest
throughout the contemplated term of the Obligations hereunder. 
 11.21. INTERCREDITOR AGREEMENTS. (a) EACH LENDER
PARTY HERETO HEREBY AUTHORIZES THE ADMINISTRATIVE AGENT AND THE COLLATERAL AGENT TO EXECUTE AND DELIVER EACH INTERCREDITOR AGREEMENT AND UPON THE REQUEST OF THE BORROWER, THE ADMINISTRATIVE AGENT AND THE COLLATERAL AGENT EACH AGREE TO EXECUTE
AND DELIVER EACH INTERCREDITOR AGREEMENT PROVIDED EACH SUCH AGREEMENT IS IN FORM AND SUBSTANCE SATISFACTORY TO EACH SUCH AGENT AND EACH LENDER PARTY UNDERSTANDS, ACKNOWLEDGES AND AGREES THAT AT ALL TIMES FOLLOWING THE EXECUTION AND DELIVERY OF
AN INTERCREDITOR AGREEMENT SUCH LENDER (AND EACH OF ITS SUCCESSORS AND ASSIGNS) SHALL BE BOUND BY THE TERMS THEREOF. 
 (b)
EACH LENDER IS RESPONSIBLE FOR MAKING ITS OWN ANALYSIS AND REVIEW OF EACH INTERCREDITOR AGREEMENT AND THE TERMS AND PROVISIONS THEREOF, AND NO AGENT OR ANY OF AFFILIATES MAKES ANY REPRESENTATION TO ANY LENDER AS TO THE SUFFICIENCY OR ADVISABILITY OF
THE PROVISIONS CONTAINED IN ANY INTERCREDITOR AGREEMENT. 

  
 128









 SECTION 12. Holdings Guaranty. 

12.01. Guaranty. In order to induce the Administrative Agent, the Collateral Agent and the Lenders to enter into this Agreement and
to extend credit hereunder, and to induce the other Guaranteed Creditors to enter into Hedging Agreements and in recognition of the direct benefits to be received by Holdings from the proceeds of the Loans and the entering into of such Hedging
Agreements, Holdings hereby agrees with the Guaranteed Creditors as follows: Holdings hereby unconditionally and irrevocably guarantees as primary obligor and not merely as surety the full and prompt payment when due, whether upon maturity,
acceleration or otherwise, of any and all of the Guaranteed Obligations of the Borrower to the Guaranteed Creditors. If any or all of the Guaranteed Obligations of the Borrower to the Guaranteed Creditors becomes due and payable hereunder, Holdings,
unconditionally and irrevocably, promises to pay such indebtedness to the Administrative Agent and/or the other Guaranteed Creditors, or order, on demand, together with any and all expenses which may be incurred by the Administrative Agent and the
other Guaranteed Creditors in collecting any of the Guaranteed Obligations. If claim is ever made upon any Guaranteed Creditor for repayment or recovery of any amount or amounts received in payment or on account of any of the Guaranteed Obligations
and any of the aforesaid payees repays all or part of said amount by reason of (i) any judgment, decree or order of any court or administrative body having jurisdiction over such payee or any of its property or (ii) any settlement or
compromise of any such claim effected by such payee with any such claimant (including the Borrower), then and in such event Holdings agrees that any such judgment, decree, order, settlement or compromise shall be binding upon Holdings,
notwithstanding any revocation of this Holdings Guaranty or other instrument evidencing any liability of the Borrower, and Holdings shall be and remain liable to the aforesaid payees hereunder for the amount so repaid or recovered to the same extent
as if such amount had never originally been received by any such payee. 
 12.02. Bankruptcy. Additionally, Holdings
unconditionally and irrevocably guarantees the payment of any and all of the Guaranteed Obligations to the Guaranteed Creditors whether or not due or payable by the Borrower upon the occurrence of any of the events specified in
Section 9.05, and irrevocably and unconditionally promises to pay such indebtedness to the Guaranteed Creditors, or order, on demand, in lawful money of the United States. 

12.03. Nature of Liability. The liability of Holdings hereunder is primary, absolute and unconditional, exclusive and independent
of any security for or other guaranty of the Guaranteed Obligations, whether executed by any other guarantor or by any other party, and the liability of Holdings hereunder shall not be affected or impaired by (a) any direction as to application
of payment by the Borrower or by any other party, or (b) any other continuing or other guaranty, undertaking or maximum liability of a guarantor or of any other party as to the Guaranteed Obligations, or (c) any payment on or in reduction
of any such other guaranty or undertaking, or (d) any dissolution, termination or increase, decrease or change in personnel by the Borrower, or (e) any payment made to any Guaranteed Creditor on the Guaranteed Obligations which any such
Guaranteed Creditor repays to the Borrower pursuant to court order in any bankruptcy, reorganization, arrangement, moratorium or other debtor relief proceeding, and Holdings waives any right to the deferral or modification of its obligations
hereunder by reason of any such proceeding, or (f) any action or inaction by the Guaranteed Creditors as contemplated in Section 12.05, or (g) any invalidity, irregularity or enforceability of all or any part of the Guaranteed
Obligations or of any security therefor. 

  
 129









 12.04. Independent Obligation. The obligations of Holdings hereunder are independent
of the obligations of any other guarantor, any other party or the Borrower, and a separate action or actions may be brought and prosecuted against Holdings whether or not action is brought against any other guarantor, any other party or the Borrower
and whether or not any other guarantor, any other party or the Borrower be joined in any such action or actions. Holdings waives, to the fullest extent permitted by law, the benefit of any statute of limitations affecting its liability hereunder or
the enforcement thereof. Any payment by the Borrower or other circumstance which operates to toll any statute of limitations as to the Borrower shall operate to toll the statute of limitations as to Holdings. 

12.05. Authorization. Holdings authorizes the Guaranteed Creditors without notice or demand (except as shall be required by
applicable statute and cannot be waived), and without affecting or impairing its liability hereunder, from time to time to: 

(i) change the manner, place or terms of payment of, and/or change or extend the time of payment of, renew, increase, accelerate or alter,
any of the Guaranteed Obligations (including any increase or decrease in the principal amount thereof or the rate of interest or fees thereon), any security therefor, or any liability incurred directly or indirectly in respect thereof, and this
Holdings Guaranty shall apply to the Guaranteed Obligations as so changed, extended, renewed or altered; 
 (ii) take and hold
security for the payment of the Guaranteed Obligations and sell, exchange, release, impair, surrender, realize upon or otherwise deal with in any manner and in any order any property by whomsoever at any time pledged or mortgaged to secure, or
howsoever securing, the Guaranteed Obligations or any liabilities (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and/or any offset there against; 

(iii) exercise or refrain from exercising any rights against the Borrower, any other Credit Party or others or otherwise act or refrain
from acting; 
 (iv) release or substitute any one or more endorsers, guarantors, the Borrower, other Credit Parties or other
obligors; 
 (v) settle or compromise any of the Guaranteed Obligations, any security therefor or any liability (including any
of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any liability (whether due or not) of the Borrower to its creditors other than the
Guaranteed Creditors; 
 (vi) apply any sums by whomsoever paid or howsoever realized to any liability or liabilities of the
Borrower to the Guaranteed Creditors regardless of what liability or liabilities of the Borrower remain unpaid; 

  
 130









 (vii) consent to or waive any breach of, or any act, omission or default under, this
Agreement, any other Credit Document, any Hedging Agreement or any of the instruments or agreements referred to herein or therein, or otherwise amend, modify or supplement this Agreement, any other Credit Document, any Hedging Agreement or any of
such other instruments or agreements; and/or 
 (viii) take any other action which would, under otherwise applicable principles
of common law, give rise to a legal or equitable discharge of Holdings from its liabilities under this Holdings Guaranty. 

12.06. Reliance. It is not necessary for any Guaranteed Creditor to inquire into the capacity or powers of Holdings or any of its
Subsidiaries or the officers, directors, partners or agents acting or purporting to act on their behalf, and any Guaranteed Obligations made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder. 

12.07. Subordination. Any indebtedness of the Borrower now or hereafter owing to Holdings is hereby subordinated to the Guaranteed
Obligations owing to the Guaranteed Creditors; and if the Administrative Agent so requests at a time when an Event of Default exists, all such indebtedness of the Borrower to Holdings shall be collected, enforced and received by Holdings for the
benefit of the Guaranteed Creditors and be paid over to the Administrative Agent on behalf of the Guaranteed Creditors on account of the Guaranteed Obligations to the Guaranteed Creditors, but without affecting or impairing in any manner the
liability of Holdings under the other provisions of this Holdings Guaranty. Prior to the transfer by Holdings of any note or negotiable instrument evidencing any such indebtedness of the Borrower to Holdings, Holdings shall mark such note or
negotiable instrument with a legend that the same is subject to this subordination. Without limiting the generality of the foregoing, Holdings hereby agrees with the Guaranteed Creditors that it will not exercise any right of subrogation which it
may at any time otherwise have as a result of this Holdings Guaranty (whether contractual, under Section 509 of the Bankruptcy Code or otherwise) until all Guaranteed Obligations have been irrevocably paid in full in cash. 

12.08. Waiver. (a) Holdings waives any right (except as shall be required by applicable statute and cannot be waived) to
require any Guaranteed Creditor to (i) proceed against the Borrower, any other guarantor or any other party, (ii) proceed against or exhaust any security held from the Borrower, any other guarantor or any other party or (iii) pursue
any other remedy in any Guaranteed Creditor’s power whatsoever. Holdings waives any defense based on or arising out of any defense of the Borrower, any other guarantor or any other party, other than payment of the Guaranteed Obligations to the
extent of such payment, based on or arising out of the disability of the Borrower, Holdings, any other guarantor or any other party, or the validity, legality or unenforceability of the Guaranteed Obligations or any part thereof from any cause, or
the cessation from any cause of the liability of the Borrower other than payment of the Guaranteed Obligations to the extent of such payment. The Guaranteed Creditors may, at their election, foreclose on any security held by the Administrative
Agent, the Collateral Agent or any other Guaranteed Creditor by one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially reasonable (to the extent such sale is permitted by applicable law), or exercise
any other right or remedy the Guaranteed Creditors may have against the Borrower or any other party, or any security, without affecting or impairing in any way the 

  
 131









 
liability of Holdings hereunder except to the extent the Guaranteed Obligations have been paid. Holdings waives any defense arising out of any such election by the Guaranteed Creditors, even
though such election operates to impair or extinguish any right of reimbursement or subrogation or other right or remedy of Holdings against the Borrower or any other party or any security. 

(b) Holdings waives all presentments, demands for performance, protests and notices, including without limitation notices of
nonperformance, notices of protest, notices of dishonor, notices of acceptance of this Holdings Guaranty, notices making any claim or demand in Holdings, and notices of the existence, creation or incurring of new or additional Guaranteed
Obligations, and promptness in commencing suit against any party. Holdings assumes all responsibility for being and keeping itself informed of the Borrower’s financial condition and assets, and of all other circumstances bearing upon the risk
of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks which Holdings assumes and incurs hereunder, and agrees that neither the Administrative Agent nor any of the other Guaranteed Creditors shall have any duty to
advise Holdings of information known to them regarding such circumstances or risks. 
 (c) Holdings waives any defense
(i) based on any lack of authority of the officers, directors, partners, or agents purporting to act on behalf of any of its Subsidiaries or any principal of any of its Subsidiaries or any defect in the formation of any of its Subsidiaries or
any principal thereof, (ii) based on the application by the Borrower of the proceeds of the Loans for purposes other than the purposes represented by the Borrower to the Lenders, (iii) based on any statute or rule of law that provides that
the obligation of a surety must be neither larger in amount nor in any other respects more burdensome than that of a principal, (iv) based on a Lender’s election, in any proceeding instituted under the Bankruptcy Code, of the application
of Section 1111 subdivision (b)(2) of the Bankruptcy Code or any successor statute and (v) any borrowing or any grant of security interest under Section 364 of the Bankruptcy Code. 

12.09. Payments. All payments made by Holdings pursuant to this Section 12 shall be made in Dollars and will be made
without setoff, counterclaim or other defense, and shall be subject to the provisions of Sections 4.02 and 4.04. 

12.10. Maximum Liability. It is the desire and intent of Holdings and the Guaranteed Creditors that this Holdings Guaranty shall
be enforced against Holdings to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. If, however, and to the extent that, the obligations of Holdings under this Holdings
Guaranty shall be adjudicated to be invalid or unenforceable for any reason (including, without limitation, because of any applicable state or federal law relating to fraudulent conveyances or transfers), then the amount of Holdings’
obligations under this Holdings Guaranty shall be deemed to be reduced and Holdings shall pay the maximum amount of the Guaranteed Obligations which would be permissible under applicable law.
