In such event, the Borrowers shall be deemed to have requested a Borrowing of Loans to be disbursed three (3) Business Days after the LC Honor Date in an amount equal to the unreimbursed amount, without regard to the minimum and multiples specified in Section 2.3(a)(i) for the principal amount of Loans, and upon such notice from the Administrative Agent to each LC Participant, each LC Participant shall make a Loan to the Borrowers not later than 3:00 p.m. (London, England time) on the date that is three (3) Business Days after the LC Honor Date, which Loan shall be in same day funds in an amount equal to such LC Participant’s Pro Rata Share of such Borrowing and otherwise in accordance with the provisions of Section 2.3(a).

If such reimbursement is not made by any LC Participant to the LC Issuer by 3:00 p.m. (London, England time) on the third Business Day after the LC Honor Date, such LC Participant shall pay interest on its Pro Rata Share thereof to the LC Issuer at a rate per annum equal to the interest that would have then accrued if the payment so made by the LC Issuer pursuant to such draw request was instead a Loan from the LC Issuer to such LC Participant pursuant to the terms hereof. The Borrowers hereby unconditionally and irrevocably authorize, empower, and direct the Administrative Agent and the LC Participants to record and otherwise treat such reimbursements by the LC Participants to the LC Issuer initially as Loans with a three (3) month Interest Period under a Borrowing requested by the Borrowers to reimburse the LC Issuer which have been transferred to the LC Participants at the Borrowers’ request.

(e) Repayment of Participations. (i) At any time after the LC Issuer has made a payment under any Letter of Credit and has received from any LC Participant reimbursement for such LC Participant’s Pro Rate Share of the payment so made by the LC Issuer, if the Administrative Agent receives for the account of the LC Issuer any payment in respect of the related payment by the LC Issuer under the relevant draw request or interest thereon (whether directly from the Borrowers or otherwise, and including payments under any standby letter of credit issued to back a Letter of Credit and proceeds of cash collateral applied thereto by the Administrative Agent), the Administrative Agent will distribute to such LC Participant its Pro Rata Share thereof in the same funds as those received by the Administrative Agent.

(iv) any statement or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid, or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

(v) payment by the LC Issuer under such Letter of Credit against presentation of a draw request or other document which does not comply with the terms of such Letter of Credit; or

(vi) any other circumstance whatsoever, whether or not similar to any of the foregoing,

provided, however, that nothing contained in this clause (f) shall be deemed to constitute a waiver of any remedies of the Borrowers in connection with such Letter of Credit or the Borrowers’ rights under Section 2.4(g).

(g) Liability of LC Issuer. The Borrowers assume all risks of any act or omission of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither the LC Issuer, any LC Participant nor any of their respective officers or directors shall be liable or responsible for:

(i) the use which may be made of any Letter of Credit or any act or omission of any beneficiary or transferee in connection therewith;

(ii) the validity, sufficiency, or genuineness of any document, or of any endorsement thereon, even if such document should prove to be in any or all respects invalid, insufficient, fraudulent, or forged;

(iii) payment by the LC Issuer against presentation of any document which does not comply with the terms of a Letter of Credit, including failure of any document to bear any reference or adequate reference to the relevant Letter of Credit; or

(iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (including the LC Issuer’s own negligence),

provided that the Borrowers shall have a claim against the LC Issuer, and the LC Issuer shall be liable to the Borrowers, to the extent of any direct, as opposed to consequential, damages suffered by the Borrowers which are found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted by reason of the LC Issuer’s willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit were in compliance with the terms of such Letter of Credit (and in such case the reimbursement obligations of the LC Participants to the

LC Issuer under Section 2.5(d) shall be suspended). Notwithstanding anything in the foregoing to the contrary, the LC Issuer may accept any document that appears on its face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

(h) Cash Collateral Account.

(i) If a Borrower is required to deposit funds in the Cash Collateral Account pursuant to this Agreement or any Loan Document, then such Borrower shall establish the Cash Collateral Account and shall execute any document and Security Agreement, including the LC Issuer’s standard form assignment of deposit accounts, that the LC Issuer requests in connection therewith to grant in favor of the Collateral Agent, for the benefit of the LC Issuer, a first priority Lien in respect of the Cash Collateral Account and the funds therein as security for the payment in full of the Obligations.

(ii) So long as no Event of Default exists, (A) the Collateral Agent may apply the funds held in the Cash Collateral Account only to the reimbursement of any LC Obligations and (B) the Collateral Agent shall release to the relevant Borrower at such Borrower’s written request any funds held in the Cash Collateral Account in an amount up to but not exceeding the excess, if any (immediately prior to the release of any such funds), of the total amount of funds held in the Cash Collateral Account over the LC Outstandings (if any). Following the occurrence and at any time during the continuation of any Event of Default, the Collateral Agent may, subject to Section 2.13 and Section 9.4(e), and in consultation with the LC Issuer and the Majority Lenders, apply any funds held in the Cash Collateral Account to the Obligations regardless of any LC Outstandings (if any) that may remain outstanding.

(iii) The Collateral Agent shall exercise reasonable care in the custody and preservation of any funds held in the Cash Collateral Account and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that which the Collateral Agent accords its own property, it being understood that the Collateral Agent shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds.

2.5 Prepayments.

(a) Optional. Each Borrower may at any time and from time to time voluntarily prepay the Loans, in whole or in part, by delivering to the Administrative Agent no later than 11:00 a.m. (London, England time) at least three (3) Business Days prior to the proposed prepayment date, irrevocable written notice specifying the proposed prepayment date and the aggregate principal amount of such prepayment. Each such voluntary prepayment shall be in an amount equal to $500,000 or a whole multiple of $100,000 in excess thereof (or, if less, the aggregate outstanding principal amount of the Loans, as the case may be). If any such notice is given, the amount specified in such notice shall be due and payable on the date specified therein.

(b) Mandatory. Each Borrower shall make a mandatory prepayment of the Loans in each of the following circumstances:

(i) Disposal. If a Borrower or any of its Subsidiaries Disposes of any property pursuant to Section 8.5(d), which results in the realization by such Person of Net Cash Proceeds in excess of $500,000 (or, if denominated in a non-Dollar currency, the Dollar Equivalent thereof calculated as of the date of receipt) whether as a single Disposal or a series of related Disposals, such Borrower shall (and shall ensure that such Subsidiary will), no later than the last day of the Interest Period in which such Net Cash Proceeds are realized (A) apply an amount equal to such Net Cash Proceeds to prepay the Loans and (B) if such prepayment occurs during the Commitment Period and if so required by the Majority Lenders, reduce the aggregate Commitments by an amount equal to such Net Cash Proceeds.

(ii) Casualty Event. If a Borrower or any of its Subsidiaries receives Casualty Proceeds in excess of $500,000 (or, if denominated in a non-Dollar currency, the Dollar Equivalent thereof calculated as of the date of receipt), such Borrower shall (and shall ensure that such Subsidiary will) no later than the last day of the Interest Period in which such Casualty Proceeds are received (A) apply an amount equal to such Casualty Proceeds to prepay the Loans and (B) if such prepayment occurs during the Commitment Period and if so required by the Majority Lenders, reduce the aggregate Commitments by an amount equal to such Casualty Proceeds; provided that if a Casualty Reinvestment Notice has been delivered in respect of the relevant Casualty Event, then such Borrower shall (and shall ensure that such Subsidiary will) no later than the last day of the Interest Period in which the Casualty Reinvestment Prepayment Date occurs (C) apply an amount equal to the Casualty Reinvestment Prepayment Amount to prepay the Loans and (D) if such prepayment occurs during the Commitment Period and if so required by the Majority Lenders, reduce the aggregate Commitments by an amount equal to the Casualty Reinvestment Prepayment Amount.

(iii) Illegality. If any Lender notifies the Administrative Agent and the Borrowers that the introduction of or any change in or in the interpretation of any Applicable Law makes it unlawful, or any Governmental Authority asserts that it is unlawful, for such Lender to maintain any Loan outstanding hereunder, then such Lender’s Commitment shall be reduced to zero and the Borrowers shall (if not prohibited by Applicable Law) prepay all outstanding Loans of such Lender no later than 11:00 a.m. (London, England time) on the last day of the then existing Interest Period for such Loans (or within such earlier time as may be required by Applicable Law).

(iv) Loans Exceed Commitments. On the date of each reduction of the aggregate Commitments pursuant to the provisions of this Agreement (including any reduction of the Commitments pursuant to Section 2.6), the Borrowers shall prepay the Loans to the extent, if any, that the aggregate unpaid principal amount of all Loans plus the LC Outstandings (if any) exceeds the lesser of (A) the aggregate Commitments as so reduced and (B) the Borrowing Base.

(v) Acceleration. Immediately upon any acceleration of the maturity of any Loans pursuant to Section 9.2 or Section 9.3, the Borrowers shall prepay all Loans in full unless, pursuant to Section 9.3, only a portion of all the Loans is so accelerated (in which case the portion so accelerated shall be so prepaid).

(c) No Additional Right; Interest; Ratable Prepayment. The Borrowers shall have no right to prepay any Loan except as provided in this Section 2.5, and all notices given pursuant to this Section 2.5 shall be irrevocable and binding upon each Borrower. Each prepayment of any Loan shall be accompanied by accrued interest on the principal amount prepaid to the date of such prepayment and breakage costs, if any, required to be paid pursuant to Section 4.4. Subject to Section 12.9(b), the amount of each prepayment shall be applied ratably to the principal amount of each Lender’s Loans in accordance with its Pro Rata Share and each prepayment occurring on or after the Commitment Reduction Date shall be applied to reduce in inverse order the remaining amortization payments required in respect of the then outstanding principal amount of the Loans pursuant to Section 2.7.

2.6 Termination or Reduction of Commitments; Increase of Commitments.

(a) Optional. The Borrowers may, upon at least three (3) Business Days’ irrevocable notice to the Administrative Agent, voluntarily terminate the unused and uncancelled portion of the Commitments in whole or reduce in part any unused and uncancelled portion of the Commitments. Unless otherwise stated in this Agreement, each such reduction of the Commitments shall be in a minimum amount of $1,000,000 and in a whole multiple of $250,000 in excess thereof. Any such termination or reduction of the Commitments shall be permanent, and shall be applied to each Lender’s Commitment in accordance with its Pro Rata Share; provided that while a Delinquent Period is in effect, the Borrowers may exercise their rights under Section 12.9(d) to reduce the Commitments of the relevant Delinquent Lender before reducing each other Lender’s Commitment in accordance with its Pro Rata Share.

(b) Mandatory. Notwithstanding anything in this Agreement to the contrary, on each Repayment Date, the aggregate Commitments of all Lenders then in effect shall be permanently reduced by an amount equal to the Commitment Reduction Amount (or, if the amount of the aggregate Commitments at such time is less than the Commitment Reduction Amount, an amount equal to such Commitments). Each such reduction shall be applied to each Lender’s Commitment in accordance with its Pro Rata Share at such time, and shall take effect without any further action on the part of such Lender, any Borrower, any Obligor, any Secured Party or any other Person.

(c) Increase of Commitments. The Borrowers shall have the right to increase the aggregate Commitments by obtaining additional funding commitments either from one or more of the Lenders (it being understood that no Lender shall have, or be deemed to have, an obligation to provide a portion of any such increase in the Commitments merely by reason of being a party hereto) or any other commercial bank or financial institution generally engaged in the business of providing corporate loans on a revolving basis; provided that (i) the aggregate amount of all such increases hereunder shall not result in the aggregate Commitments exceeding $250,000,000 at any time, (ii) any Person that provides such increase shall be subject to the approval of the Majority Lenders and the LC Issuer, such approval not to be unreasonably withheld, conditioned or delayed, (iii) any such Person assumes all of the rights and obligations of a “Lender” hereunder on terms substantially similar to those contained in the Assignment Agreement but otherwise pursuant to an assumption agreement in form and substance reasonably satisfactory to the Administrative Agent (acting on the directions of the Majority Lenders) between such Person, the Borrowers and the Administrative Agent and (iv) as a condition precedent to any such increase, the Borrowers shall deliver to the Administrative Agent a certificate of each Obligor signed by a Responsible Officer of such Obligor certifying and attaching the resolutions adopted by such Obligor approving or consenting to such increase, and certifying that,

before and after giving effect to such increase, the representations and warranties contained in this Agreement and the other Loan Documents are true and correct in all material respects with the same effect as if then made (unless stated to relate solely to an earlier date, in which case such representations and warranties shall be true and correct in all material respects as of such earlier date).

2.7 Repayment of Loans. Subject to Section 12.9(b), on each Repayment Date, the Borrowers shall repay to the Administrative Agent, for the ratable benefit of the Lenders, an outstanding principal amount of the Loans equal to the Commitment Reduction Amount.

2.8 Interest.

(a) Loans. On each Interest Payment Date, the Borrowers shall pay interest in respect of the outstanding principal amount of each Loan at a rate per annum equal at all times during the Interest Period for such Loan to LIBOR for such Interest Period plus the Applicable Margin; provided that if any circumstance in Section 2.3(b)(iii), Section 2.3(b)(iv) or Section 2.3(b)(v) occurs which results in any Loan being maintained on a basis other than LIBOR, the Borrowers shall pay interest in respect of the outstanding principal amount of such Loan at a rate per annum equal to the alternative rate identified in Section 2.3(b)(iii), Section 2.3(b)(iv) or Section 2.3(b)(v), as applicable plus the Applicable Margin at the end of each Fiscal Quarter or at such other times as may be reasonably determined by the Administrative Agent.

(b) Additional Interest; Mandatory Costs. If any Lender is required to maintain any reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities (as defined in Regulation D of the Board of Governors of the Federal Reserve System of the United States of America) or to comply with any applicable requirements of the European Central Bank, the Bank of England, the Financial Services Authority or any other Governmental Authority in connection with the advance or continuation of any Loan (including any marginal, special, emergency or supplemental reserves), then the Borrowers shall pay to such affected Lender additional interest on the unpaid principal amount of such Loan from its effective date until its repayment in full, to compensate such Lender for its cost of compliance therewith. Such additional interest shall be determined by such Lender and notified to the Borrowers through the Administrative Agent (such notice to include the calculation of such additional interest, which calculation shall be conclusive in the absence of manifest error). Any additional interest shall be due and payable on each Interest Payment Date following the date of the Administrative Agent’s notice to the Borrowers to pay any such amount.

(c) Default Interest. If a Default under Section 9.1(a) or 9.1(f) or an Event of Default shall have occurred and be continuing, then all Loans (whether or not then due) shall bear interest at a rate per annum equal to the rate that would otherwise be applicable thereto pursuant to this Section 2.8 plus an additional 2.00% per annum. In addition, all amounts (other than the principal amount of the Loans) not paid when due hereunder (including, to the extent permitted by Applicable Law, all overdue interest and fees) shall bear interest at a rate per annum equal to the rate that would have been payable if such overdue amount had been deemed to constitute a Loan with an Interest Period of three (3) months initially borrowed on the date such amount became overdue, plus an additional 2.00% per annum.

2.9 Fees. The Borrowers shall pay the following fees, all of which shall be fully earned and nonrefundable when paid (regardless of whether any Borrowing contemplated by this Agreement is requested), shall be paid in immediately available funds when due, shall not be subject to any counterclaim or set off and shall be in addition to, and not in lieu of, and any other fees, reimbursements of out-of-pocket costs and expenses payable by any Borrower under this Agreement or any other Loan Document:

(a) Commitment Fee. Subject to Section 12.9(e), the Borrowers shall pay to the Administrative Agent for the account of each Lender a commitment fee at a per annum rate equal to the Commitment Fee Rate on the average daily unused and uncancelled portion of such Lender’s Commitment, from the Closing Date until the Commitment Termination Date. The commitment fees shall be due and payable in arrears on the last day of each Fiscal Quarter after the Closing Date (and continuing thereafter through and including the Commitment Termination Date) and shall be fully earned and nonrefundable when paid, regardless of whether any Borrowing contemplated by this Agreement is requested.

(b) Letter of Credit Fees. Subject to Section 12.9(e), the Borrowers shall pay to the Administrative Agent for the pro rata benefit of the LC Issuer and the LC Participants a per annum letter of credit fee for each Letter of Credit issued hereunder in an amount equal to the Applicable Margin multiplied by the face amount of such Letter of Credit for the period such Letter of Credit is to be outstanding; provided that, for any Letter of Credit that is (i) Cash Collateralized or (ii) backed by a standby letter of credit issued by a financial institution acceptable to the LC Issuer in its sole discretion, then the per annum letter of credit fee for such Letter of Credit shall be an amount equal to 1.00% multiplied by the face amount of such Letter of Credit for the period such Letter of Credit is outstanding. On each date of issuance of any Letter of Credit, the Borrowers shall pay to the LC Issuer, solely for its own account, a fronting fee in an amount equal to 0.25% of the original maximum amount available to be drawn under such Letter of Credit. Each letter of credit fee shall be payable in advance on the date of the issuance of the Letter of Credit, and, in the case of an increase in the face amount or extension of the expiry date of such Letter of Credit only, on the date of such increase or extension. Without prejudice to the foregoing, the Borrowers also shall pay to the LC Issuer, solely for its own account, promptly on demand such other usual and customary fees associated with any transfers, amendments, drawings, negotiations or re-issuances of any Letter of Credit. Such fees and charges shall be due and payable on demand and shall be nonrefundable.

2.10 Computation of Interest and Fees. All computations of interest and fees shall be made by the Administrative Agent, on the basis of a year of three hundred and sixty (360) days, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an interest rate or fee shall be conclusive and binding for all purposes, absent manifest error.

2.11 Payment Procedures; Clawback.

(a) Payments by Borrowers. The Borrowers and each other Obligor shall make each payment required of it under this Agreement and under any other Loan Document not later than 11:00 a.m. (London, England time) on the date due in Dollars to the Administrative Agent at its Funding Office, or such other location as the Administrative Agent may designate in writing to the Borrowers or such Obligor in same day funds without deduction, set off, or counterclaim of any kind. Upon its actual receipt of such payment in same day funds without deduction, set off, or counterclaim of any kind, the Administrative Agent shall promptly thereafter calculate and cause to be distributed ratably to each Lender in accordance with such Lender’s Pro Rata Share at each Lender’s respective Funding Office

or to an account of such Lender at a bank in New York City as notified to the Administrative Agent at least five (5) Business Days prior to such distribution, like funds relating to the payment of principal, interest, fees or any other amounts (other than amounts payable solely to the Administrative Agent, the LC Issuer, or a specific Lender), and like funds relating to the payment of interest, fees or any other amounts payable to the LC Issuer for its account at its Funding Office, in each case to be applied in accordance with this Agreement. If the Administrative Agent makes a payment to a Lender or the LC Issuer in circumstances where the Administrative Agent was for any reason not in actual receipt of same day funds for such payment without deduction, set off or counterclaim (it being understood that the Administrative Agent shall have no obligation to make such a payment unless and until it actually receives such funds from the Borrowers), then such Lender or the LC Issuer (as the case may be) shall on demand therefor promptly refund such payment to the Administrative Agent together with accrued interest thereon from the date of its receipt of such payment to the date such refund is received by the Administrative Agent, such interest to be based on the rate determined by the Administrative Agent as its cost of funding for such payment.

(b) Non-Business Day Payments. If any payment of principal on a Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal on a Loan pursuant to the preceding sentence, interest thereon shall be payable at the applicable interest rate during such extension as determined by the Administrative Agent in its reasonable discretion. In the case of fees or any other amount under a Loan Document (other than principal or interest) that becomes due and payable on a day other than a Business Day, such amount shall be payable on the next succeeding Business Day.

2.12 Evidence of Indebtedness.

(a) Records of Loans. The Loans made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in accordance with its usual practice in the ordinary course of business. The accounts or records maintained by the Administrative Agent and each Lender shall be conclusive absent manifest error of the amount of the Loans made by the Lenders to the Borrowers and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrowers hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Administrative Agent, the Borrowers shall execute and deliver to such Lender (through the Administrative Agent) a Note, which shall evidence such Lender’s Loans in addition to such accounts or records. Each Lender may attach schedules to its Note and endorse thereon the date, amount and maturity of its Loans and payments with respect thereto.

(b) Records of Letters of Credit. Without prejudice to Section 2.12(a), each Lender and the Administrative Agent shall maintain in accordance with its usual practice in the ordinary course of business, one or more accounts or records evidencing each purchase and sale by such Lender of participations in Letters of Credit. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

2.13 Sharing of Payments by Lenders.

(a) General. Subject to Section 2.13(b), if any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set off, or otherwise) on account of its Loans or LC Outstandings (if any) in excess of its Pro Rata Share, such Lender (the “Purchasing Lender”) shall promptly notify the Administrative Agent to such effect and shall be deemed to have forthwith purchased from the other Lenders (other than any Delinquent Lender) participations in their Loans or LC Outstandings (if any) as shall be necessary to cause the Purchasing Lender to share the excess payment received ratably with such other Lenders; provided that if all or any portion of such excess payment is thereafter recovered by each of such Lenders, the Purchasing Lender’s purchase from such Lender shall be rescinded and such Lender shall repay to the Purchasing Lender the purchase price to the extent of its Pro Rata Share of such recovery. The Borrowers agree that any Purchasing Lender that is deemed to have purchased a participation from another Lender may, to the fullest extent permitted by Applicable Law, exercise all its rights (including the right of set off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrowers in the amount of such participation.

(b) Exceptions. Section 2.13(a) shall not apply to (i) any payment made by an Obligor to a Lender pursuant to and in accordance with the express terms of this Agreement or any other Loan Document, (ii) any consideration received by a Lender in relation to any participation granted by it or any assignment made by it in accordance with and pursuant to Section 12.7 and (iii) any payment obtained by a Lender in accordance with and pursuant to Section 12.9. In addition, nothing in this Section 2.13 shall at any time require a Lender to share with a Delinquent Lender any payment received by such Lender during the relevant Delinquent Period.

ARTICLE 3

BORROWING BASE

3.1 Initial Borrowing Base. The initial Borrowing Base in effect on the Closing Date shall be $30,000,000. Such initial Borrowing Base shall be subject to redetermination from time to time in accordance with this ARTICLE 3.

3.2 Scheduled Redeterminations.

(a) Independent Reserves Report.

(i) Closing Date Delivery. On the Closing Date, the Borrowers shall deliver to the Technical Agent and each Lender a reserves report dated as of May 7, 2009 from RPS Energy with respect to the Hydrocarbon Interests included or to be included in the Borrowing Base.

(ii) Subsequent Deliveries. Within ninety (90) days after December 31 in each year, commencing with December 31, 2009, the Borrowers shall deliver to the Technical Agent an Independent Reserves Report dated effective as of such December 31, and such other information as may be reasonably requested by the Technical Agent or any Lender with respect to the Hydrocarbon Interests included or to be included in the Borrowing Base. Within thirty (30) days after the Technical Agent’s receipt of such Independent Reserves Report and other information, the Technical Agent shall deliver to each Lender the Technical Agent’s recommendation for the redetermined Borrowing Base. Within ten (10) days after the Lenders’ receipt of the Technical Agent’s recommendation, the Technical Agent and the Majority Lenders shall redetermine the Borrowing Base in accordance with Section 3.4, and the Technical Agent shall promptly notify the Administrative Agent, the Borrowers and the Lenders of the amount of the Borrowing Base as so redetermined provided that if the Majority Lenders do not agree on a redetermined Borrowing Base, the lowest redetermined amount among the Lenders will prevail. If the redetermined amount is lower than the Borrowing Base existing prior to such redetermination, the Borrowing Base shall be equal to the redetermined amount one (1) Business Day after such notification. If the redetermined amount is greater than the Borrowing Base existing prior to such redetermination, the express written approval of the Supermajority Lenders shall be required before the redetermined amount may take effect, failing which the Borrowing Base shall remain the same as that existing prior to such redetermination.

(b) Internal Reserves Reports. Within forty-five (45) days after June 30 in each year, commencing with June 30, 2010, the Borrowers shall deliver to the Technical Agent and the Independent Reserves Engineer an Internal Reserves Report dated effective as of such June 30, and such other information as may be reasonably requested by the Technical Agent, the Independent Reserves Engineer or any Lender with respect to the Hydrocarbon Interests included or to be included in the Borrowing Base. Within thirty (30) days after the Technical Agent’s receipt of such Internal Reserves Report and other information and the completion of the Independent Reserves Engineer’s review of such Report and other information, the Technical Agent shall deliver to each Lender the Technical Agent’s and Independent Engineer’s recommendation for the redetermined Borrowing Base. Within ten (10) days after the Lenders’ receipt of the Technical Agent’s and Independent Engineer’s recommendation, the Technical Agent and the Majority Lenders shall redetermine the Borrowing Base in accordance with Section 3.4, and the Technical Agent shall promptly notify the Administrative Agent, the Borrowers and the Lenders of the amount of the Borrowing Base as so redetermined provided that if the Majority Lenders do not agree on a redetermined Borrowing Base, the lowest redetermined amount among the Lenders will prevail. If the redetermined amount is lower than the Borrowing Base existing prior to such redetermination, the Borrowing Base shall be equal to the redetermined amount one (1) Business Day after such notification. If the redetermined amount is greater than the Borrowing Base existing prior to such redetermination, the express written approval of the Supermajority Lenders shall be required before the redetermined amount may take effect, failing which the Borrowing Base shall remain the same as that existing prior to such redetermination.

(c) Late Delivery. If the Borrowers do not furnish to the Technical Agent and the Lenders the Independent Reserves Report, Internal Reserves Report or other information specified in clauses (a) or (b) above by the required date, (i) the obligation of the Lenders to advance a Loan hereunder and the obligation of the LC Issuer to issue a Letter of Credit hereunder shall be only at the option of any such Lender or LC Issuer, respectively and (ii) the Technical Agent and the Lenders may nonetheless

redetermine the Borrowing Base from time to time thereafter in their sole discretion until the Technical Agent and the Lenders receive the relevant Independent Reserves Report, Internal Reserves Report, or other information, as applicable, whereupon the Technical Agent and the Lenders shall redetermine the Borrowing Base as otherwise specified in this ARTICLE 3.

(d) Representation and Warranty. Each delivery of an Internal Reserves Report by the Borrowers to the Technical Agent and the Lenders shall constitute a representation and warranty by the Borrowers to the Technical Agent and the Lenders that (i) the Borrowers have rights with respect to the Hydrocarbon Interests specified therein pursuant to the terms of the Hydrocarbon Licenses and (ii) on and as of the date of such Reserves Report each Hydrocarbon Interest described as “proved developed” therein was developed for oil and/or gas, and the wells pertaining to such Hydrocarbon Interests described therein as “producing wells” were each producing oil and gas in paying quantities, except for wells that were utilized as water or gas injection wells or as water disposal wells. Concurrently with the delivery of each Independent Reserves Report to the Technical Agent, the Borrowers shall deliver a certificate of the Borrowers, signed by a Responsible Officer of the Borrowers, representing and warranting as to the truth, completeness and accuracy of the statements set forth in clauses (i) and (ii) of the immediately preceding sentence in respect of such matters as covered in such Independent Reserves Report.

3.3 Interim Redeterminations. With effect from the first anniversary of the Closing Date, and in addition to the scheduled redeterminations of the Borrowing Base provided for in Section 3.2, the Majority Lenders shall have the right to require one (1) interim redetermination of the Borrowing Base during any period of twelve (12) consecutive months upon giving the Technical Agent and the Borrowers at least ten (10) days’ prior written notice to such effect, and the Borrowers shall have the right to require one (1) interim determination of the Borrowing Base during any period of twelve (12) consecutive months upon giving the Technical Agent and the Lenders at least ten (10) days’ prior written notice to such effect. In connection with any redetermination of the Borrowing Base under this Section 3.3, the Borrowers shall provide the Technical Agent with such supporting information regarding the Borrowers’ business (including the Hydrocarbon Interests, the Proved Reserves, and production relating thereto) as the Technical Agent or any Lender may reasonably request, including, in the case of requests for an increase to the Borrowing Base of $1,000,000 or more, an updated Independent Reserves Report. Within thirty (30) days after the Technical Agent’s receipt of a request for an interim determination under this Section 3.3 together with such supporting information (if any) referred to in the previous sentence, the Technical Agent shall deliver to each Lender the Technical Agent’s recommendation for the redetermined Borrowing Base. Within ten (10) days after the Lenders’ receipt of the Technical Agent’s recommendation, the Technical Agent and the Majority Lenders shall redetermine the Borrowing Base in accordance with Section 3.4, and the Technical Agent shall promptly notify the Administrative Agent, the Borrowers and the Lenders of the amount of the Borrowing Base as so redetermined provided that if the Majority Lenders do not agree on a redetermined Borrowing Base, the lowest redetermined amount among the Lenders will prevail. If the redetermined amount is lower than the Borrowing Base existing prior to such redetermination, the Borrowing Base shall be equal to the redetermined amount one (1) Business Day after such notification. If the redetermined amount is greater than the Borrowing Base existing prior to such redetermination, express written approval of the Supermajority Lenders shall be required before the redetermined amount may take effect, failing which the Borrowing Base shall remain the same as that existing prior to such redetermination.

3.4 Standards for Redetermination. Each redetermination of the Borrowing Base by the Technical Agent and the Majority Lenders pursuant to this ARTICLE 3 shall be made (i) in the sole discretion of the Technical Agent and the Majority Lenders (but in accordance with the other provisions of this Section 3.4), (ii) in accordance with the Technical Agent’s and the Majority Lenders’ customary internal standards and practices for valuing and redetermining the value of Hydrocarbon Interests in connection with reserve based oil and gas loan transactions, (iii) in conjunction with the most recent Independent Reserves Report or Internal Reserves Report (as applicable) or other information received by the Technical Agent or any Lender relating to the Hydrocarbon Interests, the Proved Reserves and production relating thereto and (iv) based upon the estimated Present Value pursuant to the terms of the Hydrocarbon Licenses as determined by the Technical Agent and the Majority Lenders. In valuing and redetermining the Borrowing Base, the Technical Agent and the Majority Lenders may also consider the business, financial condition, and Indebtedness of the Borrowers and any of their Subsidiaries, any Hydrocarbon Hedge Agreements and such other factors as the Technical Agent and the Majority Lenders customarily deem appropriate, and shall be satisfied that the Present Value is at least equal to 125% of the projected future net cash flows attributable to Proved Developed Producing Reserves at such time and that such projected future net revenues will be sufficient to meet scheduled payments of principal, interest and fees under this Agreement and the other Loan Documents as and when they become due. In that regard, the Borrowers acknowledge that the determination of the Borrowing Base contains an equity cushion (market value in excess of loan value), which is essential for the adequate protection of the Technical Agent and the Lenders. No Proved Reserves shall be included or considered for inclusion in the Borrowing Base unless the Technical Agent shall have received, at the Borrowers’ expense, Security Documents, filings, legal opinions and such other appropriate documentary evidence satisfactory in form and substance to the Technical Agent confirming the existence of a Security Interest in the Hydrocarbon Licenses and the Hydrocarbon Interests pertaining thereto (to the fullest extent permissible under the laws of Turkey). At all times after the Technical Agent has given the Borrowers notification of a redetermination of the Borrowing Base under this ARTICLE 3, the Borrowing Base shall be equal to the redetermined amount until the Borrowing Base is again redetermined in accordance with this ARTICLE 3.

3.5 Borrowing Base Deficiency. If a Borrowing Base Deficiency occurs, the Technical Agent shall deliver to the Administrative Agent, the Borrowers and the Lenders as soon as reasonably practicable thereafter a notice to such effect (the “Borrowing Base Deficiency Notice”). The Borrowers shall cure the Borrowing Base Deficiency within forty-five (45) days after receipt of such Borrowing Base Deficiency Notice. In addition, the Borrowers shall deliver to the Technical Agent and the Administrative Agent (for delivery to the Lenders) within fifteen (15) days after receipt of such Borrowing Base Deficiency Notice, a written statement (the “Borrowing Base Deficiency Cure Notice”) indicating which one or combination of the following actions it intends to take to cure the Borrowing Base Deficiency:

(a) a prepayment of all or any part of the Loans pursuant to Section 2.5(a);

(b) Cash Collateralizing the LC Outstandings (if any) then in existence; or

(c) a security interest in additional Collateral, such security interest and such additional Collateral to be acceptable to the Collateral Agent and each Lender in its sole discretion.

3.6 Operational Lock-Up. Following the occurrence of a Borrowing Base Deficiency, all amounts deposited in the Collection Accounts shall be retained therein, and no withdrawals may be made therefrom except in accordance with Section 7.13.

ARTICLE 4

TAXES AND YIELD PROTECTION

4.1 Taxes.

(a) No Deduction for Certain Taxes. Any and all payments by each Obligor shall be made free and clear of and without deduction for any and all present and future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Secured Party, taxes imposed on its income by the jurisdiction under the laws of which such Secured Party is organized or any political subdivision of the jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”) and, in the case of each Secured Party, Taxes by the jurisdiction of such Secured Party’s Funding Office or any political subdivision of such jurisdiction. If any Obligor shall be required by law to deduct any Taxes from or in respect of any sum payable to any Secured Party, (i) the sum payable shall be increased as may be necessary so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 4.1), such Secured Party receives an amount equal to the sum it would have received had no such deductions been made; (ii) such Obligor shall make such deductions; and (iii) such Obligor shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with Applicable Law.

(b) Other Taxes. In addition, each Obligor shall pay (i) any present and future stamp or documentary taxes or any other excise or property taxes, intangible or mortgage recording taxes, charges or similar levies and (ii) any value added taxes imposed by the jurisdiction in which the Obligor is resident, in each of (i) and (ii) arising from any payment made or from the execution, delivery, enforcement or registration of, or otherwise with respect to, this Agreement, the Notes, or the other Loan Documents (hereinafter referred to as “Other Taxes”).

(c) Indemnification for Taxes. Each Obligor indemnifies each Secured Party for the full amount of Taxes and Other Taxes (including any Taxes and Other Taxes imposed by any jurisdiction on amounts payable under this Section 4.1) paid by such Secured Party and any liability (including interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. Each payment required to be made by an Obligor in respect of this indemnification shall be made to the Administrative Agent for the benefit of any party claiming such indemnification within thirty (30) days from the date such Obligor receives written demand therefor from the Administrative Agent on behalf of itself as Administrative Agent or any such Secured Party. If any Secured Party receives a refund in respect of any Taxes paid by an Obligor under this clause (c), such Secured Party shall promptly pay to such Obligor such Obligor’s share of such refund as reasonably determined by such Secured Party.

4.2 Increased Costs.

(a) Change in Law. If, due to either (i) the introduction of or any change in or in the interpretation of any Applicable Law after the Closing Date or (ii) the compliance with any guideline or request from any Governmental Authority (whether or not having the force of law) that becomes effective after the Closing Date, there shall be any increase in the cost to any Secured Party of agreeing to make or making, funding, or maintaining any Credit Extension (whether as a result of any consequent change in its basis of taxation, any consequent introduction of additional regulatory fees or

deposits or otherwise), then each Borrower shall from time to time, upon demand by such Secured Party (with a copy of such demand to the Administrative Agent), immediately pay to the Administrative Agent for the account of such Secured Party such additional amounts as shall be sufficient to compensate such Secured Party for such increased cost. A certificate as to the amount of such increased cost and detailing the calculation of such cost submitted to such Borrower and the Administrative Agent by such Secured Party shall be conclusive and binding for all purposes, absent manifest error.

(b) Capital Adequacy. If any Lender determines in good faith that compliance with any Applicable Law or any guideline or request from any Governmental Authority (whether or not having the force of law) that becomes effective after the Closing Date affects or would affect the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender and that the amount of such capital is increased by or based upon the existence of such Lender’s Commitment or the LC Issuer’s commitment to issue Letters of Credit, then, upon ten (10) days’ prior written notice by such Lender or the LC Issuer (with a copy of any such demand to the Administrative Agent), each Borrower shall immediately pay to the Administrative Agent for the account of such Lender or the LC Issuer from time to time as specified by it, such additional amounts as shall be sufficient to compensate such Lender or the LC Issuer, in light of such circumstances, (i) with respect to such Lender, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender’s Commitment and (ii) with respect to the LC Issuer, to the extent that the LC Issuer reasonably determines such increase in capital to be allocable to the issuance or maintenance of the Letters of Credit. A certificate as to such amounts and detailing the calculation of such amounts submitted to such Borrower by such Lender or the LC Issuer shall be conclusive and binding for all purposes, absent manifest error.

(c) Letters of Credit. If any change in any law or regulation or in the interpretation thereof by any Governmental Authority charged with the administration thereof that becomes effective after the Closing Date shall either (i) impose, modify, or deem applicable any reserve, special deposit, or similar requirement against letters of credit issued by, or assets held by, or deposits in or for the account of, the LC Issuer or (ii) impose on the LC Issuer any other condition regarding any Letter of Credit or any LC Outstandings (if any), and the result of any event referred to in the preceding clause (i) or (ii) shall be to increase the cost to the LC Issuer of issuing or maintaining any Letter of Credit (which increase in cost shall be determined by the LC Issuer’s reasonable allocation of the aggregate of such cost increases resulting from such event), then, upon demand by the LC Issuer, each Borrower shall pay to the LC Issuer, from time to time as specified by the LC Issuer, such additional amounts as shall be sufficient to compensate the LC Issuer for such increased cost. A certificate as to such increased cost incurred by the LC Issuer, as a result of any event mentioned in the preceding clause (i) or (ii), and detailing the calculation of such increased costs submitted by the LC Issuer to such Borrower, shall be conclusive and binding for all purposes, absent manifest error.

(d) Clawback Limitation. Failure or delay on the part of any Lender or the LC Issuer to demand compensation pursuant to this Section 4.2 shall not constitute a waiver of such Lender’s or the LC Issuer’s right to demand such compensation; provided that no Borrower shall be required to compensate a Lender or the LC Issuer pursuant to this Section 4.2 for any increased costs incurred or reductions suffered more than one hundred and eighty (180) days prior to the date that such Lender or the LC Issuer, as the case may be, notifies such Borrower of the event giving rise to such increased costs or reductions and of such Lender’s or the LC Issuer’s intention to claim compensation therefor (except that, if the event giving rise to such increased costs or reductions is retroactive, then the one hundred and eighty (180) day period referred to above shall be extended to include the period of retroactive effect thereof).

4.3 Mitigation Obligations. If any Lender or the LC Issuer requests compensation under Section 4.1 or Section 4.2, then such Lender or the LC Issuer shall use reasonable efforts to designate a different Funding Office for funding or booking its Loans or Letters of Credit, or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender or the LC Issuer, such designation or assignment (i) would eliminate or reduce amounts payable by each Borrower pursuant to Section 4.1 or Section 4.2 in the future and (ii) would not subject such Lender or the LC Issuer to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender or the LC Issuer, as the case may be. Each Borrower hereby agrees to pay all costs and expenses incurred by any Lender or the LC Issuer in connection with any such designation or assignment; provided that such costs and expenses incurred by any Lender or the LC Issuer in connection with any such designation or assignment are not greater than amounts payable under Section 4.1 or Section 4.2.

4.4 Breakage Costs. Each Borrower agrees to indemnify each Lender on demand for, and to hold each Lender harmless from, any Tax, loss or expense that such Lender may sustain or incur as a consequence of (a) each Borrower’s failure to borrow or continue any Loan after requesting the same, (b) each Borrower’s failure to make any prepayment of Loans after such Borrower has given a notice thereof, (c) the making of a prepayment of Loans on a day that is not the last day of an Interest Period with respect thereto or (d) receipt by an LC Participant pursuant to Section 2.4(e) of its Pro Rata Share of the amount necessary to reimburse the LC Issuer in full for any payment made by it under a Letter of Credit. Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest that would have accrued on the amount so prepaid, or not so borrowed or continued, for the period from the date of such prepayment or of such failure to borrow or continue to the last day of such Interest Period (or, in the case of a failure to borrow or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the London interbank market. A certificate as to any amounts payable pursuant to this Section 4.4 submitted by such Lender to each Borrower through the Administrative Agent shall be conclusive absent manifest error.

4.5 Survival. All of the Borrowers’ obligations under this ARTICLE 4 shall survive the termination of the Commitments and the payment in full of the Obligations.

(e) The proceeds of each Equity Cure Injection may be used by the Borrowers for general corporate purposes provided that in the period commencing on the date on which an Equity Cure Injection is made and ending on the first date thereafter on which a Compliance Certificate delivered by the Borrowers to the Administrative Agent in accordance with Section 7.1(d) demonstrates that the Borrowers are in compliance with Section 8.16, the Borrowers shall not make or pay, or permit to be made or paid, any dividend or distribution (whether in cash or in kind) in relation to their respective share capital, any redemption or reduction of their respective share capital, any payments in respect of any loans made available to them by any Affiliate or any other distribution to any of their respective shareholders.

(e) any waiver by a Secured Party of any right under this Agreement or any Loan Document in respect of the Obligations or any part thereof;

(f) any failure to perfect any Lien in respect of any Collateral, or any failure of such Lien to constitute a valid and enforceable security interest in respect of such Collateral;

(g) any substitution, release or exchange effected in respect of any Collateral; or

(h) any additional guarantee given in favor of the Secured Parties in respect of the Obligations or any part thereof.

10.3 Waiver of Presentment. Each Guarantor hereby expressly waives diligence, presentment, demand of payment, protest and all notices whatsoever, and any requirement that any Secured Party first exhaust any right, power or remedy it may have against any Borrower or any Guarantor under this Agreement or any other Loan Document, or against any other Person under any other guarantee of, or security for, any of the Obligations. Each Guarantor agrees that its obligations pursuant to this ARTICLE 10 shall not be affected by any assignment or participation entered into by any Bank pursuant to Section 12.7.

10.4 Reinstatement. The obligations of each Guarantors under this ARTICLE 10 shall automatically be reinstated if for any reason any payment by or on behalf of any Borrower or any Guarantor in respect of the Obligations is rescinded, or must be otherwise restored by any Secured Party, whether as a result of any proceedings in bankruptcy or reorganization or otherwise. Each Guarantor jointly and severally agrees to indemnify each Secured Party on demand for all costs and expenses (including, without limitation, attorney’s fees) incurred by it in connection with such rescission or restoration, including any such costs and expenses incurred in defending any claim alleging that such payment constituted a preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law.

10.5 Subrogation. Until all Commitments have been terminated and all Obligations (other than contingent Obligations not then due and payable) have been paid in full, each Guarantor hereby waives all rights of subrogation or contribution it may have in respect of any Borrower or any Guarantor, whether arising by contract or operation of law or otherwise by reason of any payment made by it pursuant to this ARTICLE 10.

10.6 Continuing Guarantee. The guarantee in this ARTICLE 10 is a continuing guarantee, and shall apply to all Obligations whenever arising.

10.7 Instrument for the Payment of Money. Each Guarantor hereby acknowledges that the guarantee in this ARTICLE 10 constitutes an instrument for the payment of money, and agrees that any Secured Party, at its sole option, in the event of a dispute by such Guarantor in the payment of any moneys due hereunder, shall have the right to bring motion-action under New York CPLR Section 3213.

10.8 General Limitation on Guarantee Obligations. In any action or proceeding involving any bankruptcy, insolvency, reorganization or other Applicable Law in the jurisdiction of organization of any Guarantor affecting the rights of creditors generally, if the obligations of any Guarantor under this ARTICLE 10 would otherwise be held or determined to be void, invalid or unenforceable, or subordinated to the claims of any other creditors, then, notwithstanding anything in this Agreement to the contrary, the amount of such liability shall, without any further action by such Guarantor, any Secured Party or any other Person, be automatically limited and reduced to the highest amount that would be valid and enforceable and not subordinated to the claims of other creditors as determined in such action or proceeding.

10.9 Joint and Several Liability of Borrowers. Without prejudice to the provisions of this ARTICLE 10 but subject to any Applicable Law in the jurisdiction of organization of any Borrower affecting the rights of creditors generally, in consideration of the financial accommodation to be provided by the Lenders under this Agreement and the Designated Hedge Counterparties under the Designated Hedge Agreements, for the mutual benefit, directly and indirectly, of each Borrower and in consideration of the undertakings of each Borrower to accept joint and several liability for the obligations of each other Borrower, each Borrower hereby irrevocably and unconditionally accepts joint and several liability with each other Borrower with respect to the prompt payment in full when due (whether at stated maturity, by acceleration or otherwise) of the Obligations of, each Borrower and all other amounts from time to time owing to the Secured Parties by each Borrower under this Agreement and all of the other Loan Documents, in each case strictly in accordance with the terms hereof and thereof.

ARTICLE 11

AGENCY PROVISIONS

11.1 Appointment and Authority. Each of the Lenders and the LC Issuer hereby irrevocably appoints Standard Bank Plc to act on its behalf as the Administrative Agent, the Collateral Agent and the Technical Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent, the Collateral Agent and the Technical Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent, the Collateral Agent and the Technical Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this ARTICLE 11 are solely for the benefit of the Secured Parties, and neither the Borrowers nor any other Obligor shall have rights as a third party beneficiary of any of such provisions. Each of the Secured Parties hereby irrevocably appoints and authorizes the Collateral Agent to act as the agent of such Secured Party for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any Obligor to secure any of the Obligations, together with such powers and discretion as are reasonably incidental thereto.

11.2 Rights as a Lender. Each Agent shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent, and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include Standard Bank Plc serving as the Administrative Agent, as the Collateral Agent or as the Technical Agent hereunder in its individual capacity. Standard Bank Plc and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with any Obligor or any Subsidiary or other Affiliate thereof as if it were not an Agent and without any duty to account therefor to the Lenders.

11.3 Exculpatory Provisions. No Agent shall have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, each Agent:

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

(b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that an Agent is required to exercise as directed in writing by the Majority Lenders (or

such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that no Agent shall be required to take any action that, in its opinion or the opinion of its counsel, may expose such Agent to liability or that is contrary to any Loan Document or Applicable Law; and

(c) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to any Borrower or any of its Affiliates that is communicated to or obtained by Standard Bank Plc or any of its Affiliates in any capacity.

No Agent shall be liable for any action taken or not taken by it (i) with the consent or at the request of the Majority Lenders or (ii) in the absence of its own gross negligence or willful misconduct. No Agent shall be deemed to have knowledge of any Default unless and until notice describing such Default is given to such Agent by an Obligor, a Lender or the LC Issuer. No Agent shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or the creation, perfection or priority of any Lien purported to be created by the Security Documents, (v) the value or the sufficiency of any Collateral or (v) the satisfaction of any condition precedent set forth in ARTICLE 5 or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to such Agent.

11.4 Reliance by Agents. Each Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. Each Agent may also rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. Without prejudice to the foregoing, in determining compliance with any condition hereunder to any Credit Extension that by its terms must be fulfilled to the satisfaction of a Lender or the LC Issuer, the Administrative Agent may presume that such condition is satisfactory to such Lender or the LC Issuer unless the Administrative Agent shall have received notice to the contrary from such Lender or the LC Issuer prior to the making of such Credit Extension. Each Agent may engage, rely on and consult with legal counsel (who may be counsel for the Borrowers), independent accountants and other professional advisors or experts selected by it, in its sole discretion and at the cost of the Borrowers, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants, professional advisors or experts.

11.5 Delegation of Duties. Each Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by such Agent. Each 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 Affiliates. The exculpatory provisions of Section 11.3 and this ARTICLE 11 shall apply to any such sub-agent and to the Affiliates of such Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities performed as an Agent.

11.6 Resignation of Agents. Each Agent may at any time give notice of its resignation to the Borrowers and the Secured Parties. Upon receipt of any such notice of resignation, the Majority Lenders shall have the right, in consultation with the Borrowers, to appoint another Person or an Affiliate of a Lender to succeed such Agent. If no such successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within thirty (30) days after the retiring Agent gives notice of its resignation, then the retiring Agent may on behalf of the Secured Parties, appoint a successor Agent meeting the qualifications set forth above; provided that if the retiring Agent shall notify the Borrowers and the Secured Parties that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (a) the retiring Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that if the retiring Agent is the Collateral Agent, the Collateral Agent shall continue to hold any Collateral held by it on behalf of the Secured Parties under any of the Loan Documents until such time as a successor Collateral Agent is appointed) and (b) all payments, communications and determinations to be made by, to or through such Agent shall instead be made by or to the relevant Obligor or Secured Party directly, until such time as a successor Agent is appointed as provided for above in this Section 11.6. Upon the acceptance of a successor’s appointment as an Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Agent, and the retiring Agent shall be discharged from all of its duties and obligations hereunder and under any other Loan Document (if not already discharged therefrom as provided above), and the retiring Agent shall cooperate in good faith to effectuate the transfer of its role to the successor Agent, including the execution and delivery of such assignments, modifications, documents, certificates and further assurances as such successor Agent may reasonably request. The fees payable by the Borrowers to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor. After the retiring Agent’s resignation hereunder and under the other Loan Documents, the provisions of this ARTICLE 12, ARTICLE 5 and Section 11.4 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Affiliates in respect of any actions taken or omitted to be taken by any of them while the retiring Agent was acting as an Agent. In addition, if any Lender serving as an Agent is or becomes a Delinquent Lender, the Majority Lenders or (so long as no Default or Event of Default has then occurred and is continuing) the Borrowers, may, but shall not be obligated to, require the resignation of such Agent in accordance with the terms of this Section 11.6; provided that such Agent shall not be required to resign if, as a result of the expiry of the Delinquent Period prior thereto, the circumstances entitling the Majority Lenders or the Borrowers to require such resignation cease to apply.

11.7 Non-Reliance on Agents and Other Lenders. Each Lender and the LC Issuer acknowledges that it has, independently and without reliance upon any Agent or any other Lender or any of their Affiliates and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and to make Credit Extensions hereunder. Each Lender and the LC Issuer also acknowledges that it will, independently and without reliance upon any Agent or any other Lender or any of their Affiliates and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

11.8 No Other Duties. Notwithstanding anything in this Agreement to the contrary, the Arrangers shall have no powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as an Agent, a Lender or the LC Issuer hereunder.

11.9 Indemnification. The Lenders shall indemnify each Agent in its capacity as such (to the extent not reimbursed by the Borrowers and without limiting the obligation of the Borrowers to do so), ratably according to their respective Pro Rata Shares in effect on the date on which indemnification is sought under this Section (or, if indemnification is sought after the date upon which the Commitments shall have terminated and the Loans shall have been paid in full, ratably in accordance with such Pro Rata Shares immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (whether before or after the payment of the Loans and other Obligations) be imposed on, incurred by or asserted against such Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein, or the other transactions contemplated hereby or thereby or any action taken or omitted by such Agent under or in connection with any of the foregoing; provided, however, that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and non-appealable decision of a court of competent jurisdiction to have resulted from such Agent’s gross negligence or willful misconduct. The agreements in this Section shall survive the termination of this Agreement and the payment in full of all Obligations.

11.10 Indemnified Matters. Notwithstanding anything to the contrary in this Agreement, each Agent shall be entitled to include as part of any amount payable to it under Section 11.9, Section 12.5 and/or Section 12.6, a sum representing the cost to such Agent in terms of management time and other resources calculated on the basis of such reasonable daily or hourly rates as such Agent may notify to the Borrower or the Lenders (as the case may be) for such purpose, and such sum shall be in addition to any fees or other amounts paid or payable to such Agent under this Agreement or the other Loan Documents. Each Borrower shall promptly on demand reimburse any Lender for amounts actually paid by such Lender pursuant to this Section 11.10.

11.11 Administrative Agent May File Proofs of Claim. In case of the pendency of any proceeding under any judicial proceeding relative to any Obligor, the Administrative Agent (irrespective of whether the principal of any Loan or LC Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrowers) shall be entitled and empowered, by intervention in such proceeding or otherwise:

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

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

and any administrator, administrative receiver, receiver, receiver and manager, liquidator, provisional liquidator, trustee, custodian, conservator or other similar official in any such judicial proceeding is hereby authorized by each Lender and the LC Issuer to make such payments to the Administrative Agent and, if the Administrative Agent shall consent to the making of such payments directly to the Lenders and the LC Issuer, to pay to the Administrative Agent any amount due for the compensation, expenses, disbursements and

advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under this Agreement and any other Loan Document. Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender or the LC Issuer any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or the LC Issuer to authorize the Administrative Agent to vote in respect of the claim of any Lender or the LC Issuer or in any such proceeding.

11.12 Collateral and Guarantee Matters. The Lenders and the LC Issuer irrevocably authorize the Collateral Agent, at its option and in its discretion:

(a) to release any Lien on any property granted to or held by the Collateral Agent under any Loan Document (i) upon the termination of the Commitments and the payment in full of all Obligations (other than contingent Obligations not then due and payable), (ii) that is Disposed or to be Disposed as part of or in connection with any Disposal permitted hereunder or under any other Loan Document or (iii) if approved, authorized or ratified in writing in accordance with Section 12.1;

(b) to release any Guarantor from its guarantee of the Obligations if such Person ceases to be a Subsidiary as a result of a transaction permitted hereunder; and

(c) to subordinate any Lien granted to or held by the Collateral Agent under any Loan Document to the holder of any Lien on such property that is permitted under Section 8.2.

Upon request by the Collateral Agent at any time, the Majority Lenders will confirm in writing the Collateral Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its guarantee of the Obligations pursuant to this Section 11.12. In each case as specified in this Section 11.12, the Collateral Agent will, at the Borrowers’ expense, execute and deliver to the applicable Obligor such documents as such Obligor may reasonably request to evidence the release of such item of Collateral from the assignment and security interest granted under the Security Documents or to subordinate its interest in such item, or to release such Guarantor from its guarantee of the Obligations, in each case in accordance with the terms of the Loan Documents and this Section 11.12.

Unless the Administrative Agent advises otherwise, the Lenders shall have ten (10) Business Days to respond to the request for such amendment or waiver.

(b) extend or increase the Commitment of any Lender, without the written consent of such Lender;

12.3 No Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising, on the part of any Secured Party, any right, remedy, power or privilege hereunder or under any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.

12.6 Indemnification. In consideration of the execution and delivery of this Agreement by the Secured Parties, each Borrower hereby indemnifies, exonerates and holds each of them and each of their respective officers, directors, employees and agents in their capacities as such (each, an “Indemnitee”) free and harmless from and against any and all actions, causes of action, suits, claims, losses, costs, liabilities and damages, and all expenses incurred in connection with any of the foregoing (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), including attorneys’ fees and disbursements reasonably incurred, whether incurred in connection with actions between or among the parties hereto or the parties hereto and third parties, and agrees to reimburse each Indemnitee upon demand for all legal and other expenses reasonably incurred by it in connection with investigating, preparing to defend or defending, or providing evidence in or preparing to serve or serving as a witness with respect to, any claim, litigation, investigation or proceeding relating to any of the foregoing (collectively, the “Indemnified Liabilities”), incurred by the Indemnitees or any of them as a result of, or arising out of, or relating to:

(i) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of any Credit Extension;

(ii) the execution, delivery, enforcement, performance and administration of this Agreement, the other Loan Documents and any agreement executed and delivered in connection therewith;

(iii) any investigation, litigation or proceeding related to any environmental cleanup, audit, noncompliance with or liability under any Environmental Law or other matter relating to the protection of the environment applicable to the operations of such Borrower or any of its Subsidiaries or any of the Hydrocarbon Interests;

(iv) the presence on or under, or the Releases from, any property owned or operated by any Obligor of any Hazardous Material regardless of whether caused by, or within the control of, such Obligor; or

(v) any Environmental Liability arising as a result of property owned, leased or operated by any Obligor (the indemnification herein shall survive the payment in full of the Obligations and the termination of all Commitments, regardless of whether such Environmental Liability is caused by, or within the control of, such Obligor);

except to the extent that Indemnified Liabilities arising for the account of a particular Indemnitee are found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted by reason of such Indemnitee’s gross negligence or willful misconduct. Without limiting the foregoing, and to the extent permitted by Applicable Law, each Borrower agrees not to assert and to cause its Subsidiaries not to assert, and hereby waives and agrees to cause its Subsidiaries to so waive, all rights for contribution or any other rights of recovery with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever kind or nature, under or related to Environmental Law, that any of them might have by statute or otherwise against any Indemnitee. It is expressly understood and agreed that to the extent that any Indemnitee is strictly liable under any Environmental Law, each Obligor’s obligation to such Indemnitee under this indemnity shall likewise be without regard to fault on the part of any Obligor with respect to the violation or condition that results in any Environmental Liability of an Indemnitee. If and to the extent that the foregoing undertaking may be unenforceable for any reason, each Obligor agrees to make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under Applicable Law. The agreements in this Section 12.6 shall survive the making of the Credit Extensions hereunder, the payment in full of the Obligations and the termination of all Commitments.

12.7 Successors and Assigns.

(a) Successors and Assigns Generally. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors and assigns, provided that (i) no Obligor may assign or transfer any of its rights or obligations under this Agreement without the prior written consent of all of the Lenders and (ii) any assignment or participation by a Lender of any of its rights and obligations hereunder shall be effected in accordance with this Section 12.7.

(b) Participations. Each Lender may at any time grant participations in any of its rights under this Agreement or under any of the Notes to any Person (a “Participant”), provided that in the case of any such participation:

(i) the Participant shall not have any rights under this Agreement or any of the other Loan Documents, including rights of consent, approval or waiver (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);

(ii) such Lender’s obligations under this Agreement (including, without limitation, its Commitments hereunder) shall remain unchanged;

(iii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations;

(iv) such Lender shall remain the holder of the Obligations owing to it and of any Note issued to it for all purposes of this Agreement; and

(v) the Borrowers, the Agents, and the other Lenders shall continue to deal solely and directly with the selling Lender in connection with such Lender’s rights and obligations under this Agreement, and all amounts payable by the Borrowers hereunder shall be determined as if such Lender had not sold such participation,

and provided further that no Lender shall transfer, grant or sell any participation under which the Participant shall have rights to approve any amendment to or waiver of this Agreement or any other Loan Document.

(c) Assignments by Lender. Each Lender (the “Assignor”) may assign all or any part of its Loans, LC Participations and/or Commitments and its rights and obligations hereunder to one or more Eligible Assignees, each of which shall become a party to this Agreement as a Lender by execution of an assignment and acceptance agreement in substantially the form attached hereto as Exhibit E (an “Assignment Agreement”) to be executed by the Assignor, an Eligible Assignee and acknowledged by the Administrative Agent; provided, that (i) if such assignment is in respect of less than all of the rights and obligations of the Assignor, then, unless otherwise agreed to by the Administrative Agent, such assignment shall be in an aggregate principal amount of at least $5,000,000 or a whole multiple of $500,000 in excess thereof and (ii) each Borrower shall cooperate with the Assignor, such Eligible Assignee and the Administrative Agent to facilitate such assignment, including, if instructed by the Assignor or the Administrative Agent, providing to such Eligible Assignee copies of all documentation and other information required by bank regulatory authorities under applicable “know-your-customer” and anti-money laundering rules and regulations, including the USA PATRIOT Act, the United Kingdom Proceeds of Crime Act 2002 and the United Kingdom Money Laundering Regulations 2003. Upon its receipt of an Assignment Agreement executed by the Assignor and an Eligible Assignee, together with a registration and processing fee of $3,500 for its own account, the Administrative Agent shall promptly record the information contained therein in the Register (as defined in clause (d) below). Upon such execution, delivery, acceptance and recording, then, from and after the settlement date specified in such Assignment Agreement, the Assignee thereunder shall be a party to this Agreement and, to the extent provided in the Assignment Agreement, shall have the

rights and obligations of the Assignor hereunder with Loans and/or Commitments as specified therein and y) the Assignor thereunder shall, to the extent provided in the assignment and acceptance agreement, be released from its obligations under this Agreement.

(d) Register. The Administrative Agent shall maintain a register (the “Register”) on which the Administrative Agent shall record the name and address of each Lender, and the Commitments of, and principal amounts of the Loans and LC Obligations owing to, each Lender pursuant to the terms hereof from time to time. The entries in the Register shall be conclusive absent manifest error, and the Borrowers, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as the owner thereof for all purposes of this Agreement, notwithstanding notice to the contrary; provided that the Administrative Agent’s failure to make any recording, or any error by the Administrative Agent in making such recording, shall not affect each Borrower’s or any other Obligor’s liabilities in respect of the Loans and LC Obligations.

12.8 Right of Set-off. 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, each Agent, each Lender and the LC Issuer is hereby authorized at any time and from time to time, without presentment, demand, protest or other notice of any kind to any Borrower 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 such Agent, such Lender or the LC Issuer (including, without limitation, by branches, agencies and Affiliates of such Agent, such Lender or the LC Issuer wherever located) to or for the credit or the account of any Borrower against and on account of the Obligations, regardless of whether or not such Agent, such Lender or the LC Issuer shall have made any demand hereunder and regardless of whether or not such Obligations shall be contingent or unmatured. Each Agent, each Lender and the LC Issuer agrees to promptly notify the relevant Borrower after any such set off and application, but failure to give such notice shall not affect the validity of such set off and application.

12.9 Delinquent Lenders. Notwithstanding anything in this Agreement to the contrary, if any Lender becomes a Delinquent Lender, then, to the extent permitted by Applicable Law:

(a) while the relevant Delinquent Period is in effect, such Delinquent Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in Section 12.1;

(b) until such time as all Delinquent Credits with respect to such Delinquent Lender have been funded, its Pro Rata Share of any repayment or prepayment of the Loans shall be applied to satisfy its obligation to fund such Delinquent Credits;

(c) until such time as all Delinquent Payments with respect to such Delinquent Lender have been paid in full together with any applicable accrued interest thereon, the Administrative Agent shall apply any amounts thereafter received by the Administrative Agent for the account of such Delinquent Lender to satisfy such Delinquent Lender’s obligation to make such Delinquent Payments;

(d) while the relevant Delinquent Period is in effect, the Borrowers may reduce all or any portion of the unused Commitments of such Delinquent Lender under Section 2.6(a) before reducing the unused Commitments of any other Lender;

(e) any Delinquent Lender with a Delinquent Credit shall not be entitled to receive any commitment fee pursuant to Section 2.9(a) during its Delinquent Period, and the Borrowers shall not be required to pay any such fee that otherwise would have been required to have been paid to such Delinquent Lender during its Delinquent Period;

(f) any Delinquent Lender with a Delinquent Credit shall not be entitled to receive its share of any letter of credit fee pursuant to Section 2.9(b) during its Delinquent Period and such fee shall instead be paid to the LC Issuer (or if the entire LC Participation of such Delinquent Lender has been assumed by one or more Lenders, such fee shall be ratably allocated among such Lenders as their interests may appear), unless such Delinquent Lender has provided cash collateral or other credit support or made other arrangements to the LC Issuer’s satisfaction to ensure its ability to fund its future LC Participation in respect of any relevant Letter of Credit; and

(g) the Borrowers may, at their sole expense and effort, upon ten (10) Business Days’ notice to such Delinquent Lender and the Administrative Agent, require the Delinquent Lender to assign and delegate all of its rights, interests and obligations under this Agreement to an Eligible Assignee; provided that if the Borrowers elect to exercise such right with respect to a Delinquent Lender, (i) such Delinquent Lender shall have received payment of an amount equal to the outstanding principal of its Loans and LC Participations, accrued interest thereon, accrued fees and all other amounts then payable to it hereunder and the other Loan Documents, net of any amounts owing to any Agent, Lender or the LC Issuer, from the Eligible Assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrowers (in the case of all other amounts), (ii) the Eligible Assignee shall have paid in full all amounts then due and payable by the Delinquent Lender to any Agent, Lender or the LC Issuer hereunder and the other Loan Documents, (iii) such Delinquent Lender shall execute and deliver an Assignment Agreement and (iv) such Delinquent Lender shall not be required to make any such assignment if, as a result of the expiry of the Delinquent Period prior thereto, the circumstances entitling the Borrowers to require such assignment and delegation cease to apply.

12.10 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an executed signature page of this Agreement by facsimile or electronic transmission shall be effective as delivery of a manually executed counterpart hereof.

12.11 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

12.12 Other Transactions. Nothing contained herein shall preclude any Secured Party or any of its Affiliates from engaging in any transaction, in addition to those contemplated by the Loan Documents, with each Borrower or any of its Affiliates in which such Borrower or such Affiliate is not restricted hereby from engaging with any other Person.

12.13 Integration. This Agreement and the other Loan Documents constitute the entire understanding among the parties hereto with respect to the subject matter hereof and thereof and supersede any prior agreements, written or oral, with respect thereto.

(b) EACH OBLIGOR IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF NEW YORK AT THE ADDRESS FOR NOTICES SPECIFIED IN SECTION 12.2.

12.16 Acknowledgments. Each Obligor hereby acknowledges that:

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

(b) each Agent and each other Secured Party has no fiduciary relationship with or duty to it arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between each Agent and each other Secured Party, on the one hand, and each Borrower, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

(c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the transactions contemplated hereby among each Obligor and the Lender.

12.17 USA PATRIOT Act Notice. Each Lender, the LC Issuer and each Agent hereby notifies the Obligors that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), the United Kingdom Proceeds of Crime Act 2002 and the United Kingdom Money Laundering Regulations 2003 (as amended) or similar legislation in another country, it is required to obtain, verify and record information (and, if applicable, to provide such information particularly to an assignee) that identifies each Obligor and each of its shareholders, directors and/or officers, which information includes or may include the name and address of each such Person, the Organic Documents of each Obligor and such other information that will allow each Secured Party to comply with its obligations under the Patriot Act, the United Kingdom Proceeds of Crime Act 2002 and the United Kingdom Money Laundering Regulations 2003(as amended) or such similar legislation in another country.

12.18 Confidential Information. Each Secured Party agrees to hold all Confidential Information provided to it by any Obligor pursuant to this Agreement in accordance with its customary procedures for handling confidential information of this nature; provided, that nothing herein shall prevent each Lender from disclosing any such information (a) to any Participant or Eligible Assignee (or any prospective Participant or Eligible Assignee) that agrees to be bound by this Section 12.18, (b) on a confidential basis to its employees, directors, agents, attorneys, accountants and other professional advisers or those of any of its Affiliates, (c) upon the request or demand of any Governmental Authority, (d) in response to any order of any court or other Governmental Authority or as may otherwise be required pursuant to any Applicable Law, (e) if requested or required to do so in connection with any litigation or similar proceeding, (f) that has been publicly disclosed without violation of this Section 12.18, (g) to the National Association of Insurance Commissioners or any similar organization or other regulatory body or any nationally recognized rating agency, in each case, in any

country or other jurisdiction, that requires access to information about the Lender’s investment portfolio in connection with ratings issued with respect to the Lender or (h) in connection with the exercise of any if its rights, powers or remedies hereunder or under any other Loan Document. Except as may be required by an order of a court of competent jurisdiction and to the extent specified therein, each Lender shall not be obligated or required to return any materials furnished to it pursuant to any Loan Document by any Obligor. For purposes of this Section, “Confidential Information” means all information received from any Obligor or any Affiliate thereof relating to any Obligor or any Affiliate thereof or their respective businesses, other than any such information that is available to each Lender on a nonconfidential basis prior to disclosure by any Obligor or any Affiliate thereof, provided that, in the case of information received from an Obligor or any such Affiliate after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Confidential Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Confidential Information as such Person would accord to its own confidential information.

12.19 Public Information. The Parent hereby acknowledges that each Agent may make available to the Lenders and the LC Issuer materials and/or information provided by or on behalf of the Parent, the Borrowers or any other Obligor (collectively, the “Materials”) by posting such Materials on IntraLinks or another similar electronic system (the “Platform”) and that certain of the Lenders (each, a “Public Lender”) may have personnel who do not wish to receive material non-public information with respect to the Parent or its securities, and who may be engaged in investment and other market-related activities with respect to the Parent’s securities. The Parent hereby agrees that (w) all Materials that are to be made available to Public Lenders shall be clearly and conspicuously marked “PUBLIC” which, at a minimum, means that the word “PUBLIC” shall appear prominently on the first page thereof; (x) by marking any Materials “PUBLIC,” the Parent shall be deemed to have authorized each Agent and the Lenders to treat such Materials as not containing any material non-public information (although the parties acknowledge that such information may still be confidential, sensitive and/or proprietary) with respect to the Parent or its securities for purposes of United States federal and state securities laws, (y) all Materials marked “PUBLIC” are permitted to be made available through a portion of the Platform designated as “Public Side Information”, and (z) each Agent shall be entitled to treat any Materials that are not marked “PUBLIC” as being suitable only for posting on a portion of the Platform that is not designated as “Public Side Information.” For purposes of clarification, (i) any materials not marked “PUBLIC” shall be deemed to be material non-public information and (ii) notwithstanding the foregoing, the Parent shall be under no obligation to mark any particular Material “PUBLIC”.

12.20 WAIVER OF JURY TRIAL. THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE TO THE FULLEST EXTENT PERMITTED BY LAW ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, EACH LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE PARTIES IN CONNECTION THEREWITH. EACH OBLIGOR ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF EACH OTHER LOAN DOCUMENT TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR EACH LENDER TO ENTER INTO THE LOAN DOCUMENTS.

12.21 Judgment Currency. If, under any Applicable Law and whether pursuant to a judgment being made or registered against an Obligor or the bankruptcy of the Obligor or for any other reason, any payment under or in connection with this Agreement or any Loan Document is made or falls to be satisfied in a currency (the “Payment Currency”) other than Dollars, then to the extent that the amount of such payment actually received by an Agent or any Secured Party when converted into Dollars at the applicable rate of exchange at such time, falls short of the amount due under or in connection with this Agreement or such Loan Document, the Obligors, as a separate and independent obligation, shall indemnify and hold harmless such Agent and such Secured Party against the amount of such shortfall. For the purposes of this Section, “rate of exchange” means the rate at which an Agent or the relevant Secured Party is able on or about the date of such payment to purchase Dollars with the Payment Currency and shall take into account any premium and other costs of exchange actually incurred with respect thereto.

12.22 Australian Entities Reorganization. Notwithstanding any other provision of this Agreement, each of Incremental Petroleum (Selmo) and PEMI may be reorganized under Bahamian law (such transaction, the “Reorganization”) provided that (i) such Reorganization will be consummated in compliance with all applicable laws (including the laws of Australia and the Bahamas) and all necessary or desirable (in the reasonable discretion of the Agents) consents, approvals and filings shall have been obtained in compliance with such laws, (ii) the Collateral Agent will continue at all times following such Reorganization to have under all applicable laws (and all jurisdictions as the Collateral Agent reasonably requests) a valid, legal and first priority perfected security interest in all the assets of, and (in the case of PEMI) all of the equity interests in, Incremental Petroleum (Selmo) and PEMI for the benefit of the Secured Parties, (iii) all documents and instruments, including all filings required by law or reasonably requested by the Collateral Agent to be executed, filed, registered or recorded to create or continue the Liens intended to be created by the Security Documents (in each case, including any supplements thereto) and perfect such Liens to the extent required by, and with the priority required by, the Security Documents, shall have been filed, registered or recorded, (iv) each Obligor shall have obtained all consents and approvals required to be obtained by it in connection with (a) the execution and delivery of all Security Documents (or supplements thereto) to which it is a party and the granting by it of the Liens thereunder and (b) the performance of its obligations thereunder, (v) no Default or Event of Default exists at the time of the Reorganization or is expected to occur or continue as a result thereof, (vi) no security interest purported to be created by any Security Document shall cease to be a valid and perfected security interest (perfected as or having the priority required by this Agreement or the relevant Security Document and subject to such limitations and restrictions as are set forth herein and therein) in the securities, assets or properties covered thereby as a result of the Reorganization, (vii) the Guarantees of any of the Obligations shall continue to be in full force and effect, (viii) the Obligations shall continue to constitute senior secured indebtedness of the Obligors and continue to be legal, valid and binding obligations of the parties thereto, enforceable in accordance with their terms, (ix) no Material Adverse Effect could result from the Reorganization and (x) the Lenders shall have received legal opinions from all applicable counsel to the Obligors, acceptable in form and substance to the Lenders, confirming the matters set forth in clauses (iii), (iv), (v), (vi), (vii), (viii) and (ix) above.
