Unless the Administrative Agent shall have been notified by any Lender prior to the date of any such Borrowing that such Lender does not intend to make available to the Administrative Agent its portion of the Borrowing or Borrowings to be made on such date, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date of Borrowing, and the Administrative Agent, in reliance upon such assumption, may (in its sole discretion and without any obligation to do so) make available to the Borrower a corresponding amount.

The Administrative Agent shall also be entitled to recover from such Lender or the Borrower, as the case may be, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Administrative Agent to the Borrower to the date such corresponding amount is recovered by the Administrative Agent, at a rate per annum equal to (i) if paid by such Lender, the Overnight Rate or (ii) if paid by the Borrower, the then-applicable rate of interest or fees, calculated in accordance with Section 2.8, for the respective Loans.

(c)        Nothing in this Section 2.4 shall be deemed to relieve any Lender from its obligation to fulfill its commitments hereunder or to prejudice any rights that the Borrower may have against any Lender as a result of any default by such Lender hereunder (it being understood, however, that no Lender shall be responsible for the failure of any other Lender to fulfill its commitments hereunder).

2.5        Repayment of Loans; Evidence of Debt.

(a)        The Borrower hereby promises to pay to each Lender on the Maturity Date its then outstanding Loans pursuant to Section 5.3(a).

(b)        Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to the appropriate lending office of such Lender resulting from each Loan made by such lending office from time to time, including the amounts of principal and interest payable and paid to such lending office from time to time under this Agreement.

(c)        The Administrative Agent, on behalf of the Borrower, shall maintain the Register pursuant to Section 13.6(b), and a subaccount for each Lender, in which Register and subaccounts (taken together) shall be recorded (i) the amount of each Loan made hereunder, the Type of each Loan made and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each

46

Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder from the Borrower and each Lender’s share thereof.

(d)        The entries made in the Register and accounts and subaccounts maintained pursuant to clauses (b) and (c) of this Section 2.5 shall, to the extent permitted by applicable Requirements of Law, be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of any Lender or the Administrative Agent to maintain such account, such Register or such subaccount, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrower to repay (with applicable interest) the Loans made to the Borrower by such Lender in accordance with the terms of this Agreement.

2.6        Conversions and Continuations.

(a)        Subject to the penultimate sentence of this clause (a), (i) the Borrower shall have the option on any Business Day to convert all or a portion equal to at least the Minimum Borrowing Amount (and in multiples of $100,000 in excess thereof) of the outstanding principal amount of Loans of one Type into a Borrowing or Borrowings of another Type and (ii) the Borrower shall have the option on any Business Day to continue the outstanding principal amount of any LIBOR Loans as LIBOR Loans for an additional Interest Period; provided that (A) no partial conversion of LIBOR Loans shall reduce the outstanding principal amount of LIBOR Loans made pursuant to a single Borrowing to less than the Minimum Borrowing Amount, (B) ABR Loans may not be converted into LIBOR Loans if a Default or Event of Default is in existence on the date of the conversion and the Administrative Agent has or the Majority Lenders have determined in its or their sole discretion not to permit such conversion, (C) LIBOR Loans may not be continued as LIBOR Loans for an additional Interest Period if a Default or Event of Default is in existence on the date of the proposed continuation and the Administrative Agent has or the Majority Lenders have determined in its or their sole discretion not to permit such continuation, and (D) Borrowings resulting from conversions pursuant to this Section 2.6 shall be limited in number as provided in Section 2.2. Each such conversion or continuation shall be effected by the Borrower by giving the Administrative Agent at the Administrative Agent’s Office prior to 1:00 p.m. at least (1) three Business Days’, in the case of a continuation of or conversion to LIBOR Loans or (2) the date of conversion, in the case of a conversion into ABR Loans, prior written notice (or telephonic notice promptly confirmed in writing) (each, a “Notice of Conversion or Continuation”) specifying the Loans to be so converted or continued, the Type of Loans to be converted into or continued and, if such Loans are to be converted into or continued as LIBOR Loans, the Interest Period to be initially applicable thereto (if no Interest Period is selected, the Borrower shall be deemed to have selected an Interest Period of one month’s duration). The Administrative Agent shall give each applicable Lender notice as promptly as practicable of any such proposed conversion or continuation affecting any of its Loans.

(b)        If any Default or Event of Default is in existence at the time of any proposed continuation of any LIBOR Loans and the Administrative Agent has or the Majority Lenders have determined in its or their sole discretion not to permit such continuation, such LIBOR Loans shall be automatically converted on the last day of the current Interest Period into ABR Loans. If upon the expiration of any Interest Period in respect of LIBOR Loans, the Borrower

47

has failed to elect a new Interest Period to be applicable thereto as provided in clause (a) above, the Borrower shall be deemed to have elected to convert such Borrowing of LIBOR Loans into a Borrowing of ABR Loans, effective as of the expiration date of such current Interest Period.

2.7        Pro Rata Borrowings.   Each Borrowing of Loans under this Agreement shall be made by the Lenders pro rata on the basis of their then applicable Commitment Percentages. It is understood that (a) no Lender shall be responsible for any default by any other Lender in its obligation to make Loans hereunder and that each Lender severally but not jointly shall be obligated to make the Loans provided to be made by it hereunder, regardless of the failure of any other Lender to fulfill its commitments hereunder and (b) failure by a Lender to perform any of its obligations under any of the Credit Documents shall not release any Person from performance of its obligation under any Credit Document.

2.8        Interest.

(a)        The unpaid principal amount of each ABR Loan shall bear interest from the date of the Borrowing thereof until maturity (whether by acceleration or otherwise) at a rate per annum that shall at all times be the Applicable Margin plus the ABR, in each case, in effect from time to time.

(b)        The unpaid principal amount of each LIBOR Loan shall bear interest from the date of the Borrowing thereof until maturity thereof (whether by acceleration or otherwise) at a rate per annum that shall at all times be the Applicable Margin plus the relevant LIBOR Rate, in each case, in effect from time to time.

(c)        If all or a portion of (i) the principal amount of any Loan or (ii) any interest payable thereon shall not be paid when due (whether at stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum that is (the “Default Rate”) (A) in the case of overdue principal, the rate that would otherwise be applicable thereto plus 2% or (B) in the case of any overdue interest, to the extent permitted by applicable Requirements of Law, the rate described in Section 2.8(a) plus 2% from the date of such non-payment to the date on which such amount is paid in full (after as well as before judgment).

(d)        Interest on each Loan shall accrue from and including the date of any Borrowing to but excluding the date of any repayment thereof and shall be payable in Dollars; provided that any Loan that is repaid on the same date on which it is made shall bear interest for one day. Except as provided below, interest shall be payable (i) in respect of each ABR Loan, quarterly in arrears on the last Business Day of each March, June, September and December, (ii) in respect of each LIBOR Loan, on the last day of each Interest Period applicable thereto and, in the case of an Interest Period in excess of three months, on each date occurring at three-month intervals after the first day of such Interest Period, (iii) in respect of each Loan, (A) on any prepayment (on the amount prepaid), (B) at maturity (whether by acceleration or otherwise) and (C) after such maturity, on demand.

(e)        All computations of interest hereunder shall be made in accordance with Section 5.5.

48

(f)         The Administrative Agent, upon determining the interest rate for any Borrowing of LIBOR Loans, shall promptly notify the Borrower and the relevant Lenders thereof. Each such determination shall, absent clearly demonstrable error, be final and conclusive and binding on all parties hereto.

2.9        Interest Periods. At the time the Borrower gives a Notice of Borrowing or Notice of Conversion or Continuation in respect of the making of, or conversion into or continuation as, a Borrowing of LIBOR Loans in accordance with Section 2.6(a), the Borrower shall give the Administrative Agent written notice (or telephonic notice promptly confirmed in writing) of the Interest Period applicable to such Borrowing, which Interest Period shall, at the option of the Borrower be a one, two, three or six or (if available to all the Lenders making such LIBOR Loans as determined by such Lenders in good faith based on prevailing market conditions) a 9- or 12-month period or any period shorter than one-month requested by the Borrower.

Notwithstanding anything to the contrary contained above:

(a)        the initial Interest Period for any Borrowing of LIBOR Loans shall commence on the date of such Borrowing (including the date of any conversion from a Borrowing of ABR Loans) and each Interest Period occurring thereafter in respect of such Borrowing shall commence on the day on which the next preceding Interest Period expires;

(b)        if any Interest Period relating to a Borrowing of LIBOR Loans begins on the last Business Day of a calendar month or begins on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period, such Interest Period shall end on the last Business Day of the calendar month at the end of such Interest Period;

(c)        if any Interest Period would otherwise expire on a day that is not a Business Day, such Interest Period shall expire on the next succeeding Business Day; provided that, if any Interest Period in respect of a LIBOR Loan would otherwise expire on a day that is not a Business Day, but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall expire on the next preceding Business Day; and

(d)        the Borrower shall not be entitled to elect any Interest Period in respect of any LIBOR Loan if such Interest Period would extend beyond the Maturity Date.

2.10      Increased Costs, Illegality, Etc.

(a)        In the event that (x) in the case of clause (i) below, the Administrative Agent or (y) in the case of clauses (ii) and (iii) below, any Lender, shall have reasonably determined (which determination shall, absent clearly demonstrable error, be final and conclusive and binding upon all parties hereto):

(i)         on any date for determining the LIBOR Rate for any Interest Period that (A) deposits in the principal amounts of the Loans comprising such LIBOR Borrowing are not generally available in the relevant market or (B) by reason of any changes arising on or after the Closing Date affecting the interbank LIBOR market, adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the definition of LIBOR Rate; or

49

(ii)        that, due to a Change in Law occurring at any time or after the Closing Date, which Change in Law shall (A) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender, (B) subject any Lender to any tax of any kind whatsoever with respect to this Agreement or any LIBOR Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof or (C) impose on any Lender or the London interbank market any other condition, cost or expense affecting this Agreement or LIBOR Loans made by such Lender, the cost to such Lender of making, converting into, continuing or maintaining LIBOR Loans or participating in Letters of Credit (in each case hereunder) shall increase by an amount which such Lender reasonably deems material or the amounts received or receivable by such Lender hereunder with respect to the foregoing shall be reduced; or

(iii)       at any time, that the making or continuance of any LIBOR Loan has become unlawful as a result of compliance by such Lender in good faith with any Requirement of Law (or would conflict with any such Requirement of Law not having the force of law even though the failure to comply therewith would not be unlawful);

then, and in any such event, such Lender (or the Administrative Agent, in the case of clause (i)  above) shall within a reasonable time thereafter give notice (if by telephone, confirmed in writing) to the Borrower and to the Administrative Agent of such determination (which notice the Administrative Agent shall promptly transmit to each of the other Lenders). Thereafter (x) in the case of clause (i) above, LIBOR Loans shall no longer be available until such time as the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice by the Administrative Agent no longer exist (which notice the Administrative Agent agrees to give at such time when such circumstances no longer exist), and any Notice of Borrowing or Notice of Conversion given by the Borrower with respect to LIBOR Loans that have not yet been incurred shall be deemed rescinded by the Borrower, (y) in the case of clause (ii) above, the Borrower shall pay to such Lender, promptly (but no later than fifteen days) after receipt of written demand therefor such additional amounts as shall be required to compensate such Lender for such increased costs or reductions in amounts receivable hereunder (it being agreed that a written notice as to the additional amounts owed to such Lender, showing in reasonable detail the basis for the calculation thereof, submitted to the Borrower by such Lender shall, absent clearly demonstrable error, be final and conclusive and binding upon all parties hereto) and (z) in the case of clause (iii) above, the Borrower shall take one of the actions specified in Section 2.10(b) as promptly as possible and, in any event, within the time period required by applicable Requirements of Law.

(b)        At any time that any LIBOR Loan is affected by the circumstances described in Section 2.10(a)(ii) or (iii), the Borrower may (and in the case of a LIBOR Loan affected pursuant to Section 2.10(a)(iii) shall) either (i) if the affected LIBOR Loan is then being made pursuant to a Borrowing, cancel such Borrowing by giving the Administrative Agent telephonic notice (confirmed promptly in writing) thereof on the same date that the Borrower was notified by a Lender pursuant to Section 2.10(a)(ii) or (iii) or (ii) if the affected LIBOR Loan is then outstanding, upon at least three Business Days’ notice to the Administrative Agent, require the affected Lender to convert each such LIBOR Loan into an ABR Loan; provided that if more than

50

one Lender is affected at any time, then all affected Lenders must be treated in the same manner pursuant to this Section 2.10(b).

(c)        If, after the Closing Date, any Change in Law relating to capital adequacy of any Lender or compliance by any Lender or its parent with any Change in Law relating to capital adequacy occurring after the Closing Date, has or would have the effect of reducing the rate of return on such Lender’s or its parent’s capital or assets as a consequence of such Lender’s commitments or obligations hereunder to a level below that which such Lender or its parent could have achieved but for such Change in Law (taking into consideration such Lender’s or its parent’s policies with respect to capital adequacy), then from time to time, promptly (but in any event no later than fifteen days) after written demand by such Lender (with a copy to the Administrative Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender or its parent for such reduction, it being understood and agreed, however, that a Lender shall not be entitled to such compensation as a result of such Lender’s compliance with, or pursuant to any request or directive to comply with, any applicable Requirement of Law as in effect on the Closing Date. Each Lender, upon determining in good faith that any additional amounts will be payable pursuant to this Section 2.10(c), will give prompt written notice thereof to the Borrower, which notice shall set forth in reasonable detail the basis of the calculation of such additional amounts, although the failure to give any such notice shall not, subject to Section 2.13, release or diminish the Borrower’s obligations to pay additional amounts pursuant to this Section 2.10(c) upon receipt of such notice.

(d)        It is understood that this Section 2.10 shall not apply to (i) Taxes indemnifiable under Section 5.4, (ii) net income taxes and franchise and excise taxes (imposed in lieu of net income taxes) imposed on any Agent or Lender or (iii) Taxes included under clauses (c), (d) or (e) of the definition of Excluded Taxes.

2.11       Compensation. If (a) any payment of principal of any LIBOR Loan is made by the Borrower to or for the account of a Lender other than on the last day of the Interest Period for such LIBOR Loan as a result of a payment or conversion pursuant to Sections 2.5, 2.6, 2.10, 5.1, 5.2 or 13.7, as a result of acceleration of the maturity of the Loans pursuant to Section 11 or for any other reason, (b) any Borrowing of LIBOR Loans is not made on the date specified in a Notice of Borrowing, (c) any ABR Loan is not converted into a LIBOR Loan on the date specified in a Notice of Conversion or Continuation, (d) any LIBOR Loan is not continued as a LIBOR Loan on the date specified in a Notice of Conversion or Continuation or (e) any prepayment of principal of any LIBOR Loan is not made as a result of a withdrawn notice of prepayment pursuant to Section 5.1 or 5.2, the Borrower shall after the Borrower’s receipt of a written request by such Lender (which request shall set forth in reasonable detail the basis for requesting such amount), pay to the Administrative Agent (within fifteen days after such request) for the account of such Lender any amounts required to compensate such Lender for any additional losses, costs or expenses that such Lender may reasonably incur as a result of such payment, failure to convert, failure to continue or failure to prepay, including any loss, cost or expense (excluding loss of anticipated profits) actually incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such LIBOR Loan.

51

2.12      Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.10(a)(ii), 2.10(a)(iii), 2.10(c), 3.5 or 5.4 with respect to such Lender, it will, if requested by the Borrower use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans affected by such event; provided that such designation is made on such terms that such Lender and its lending office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of any such Section. Nothing in this Section 2.12 shall affect or postpone any of the obligations of the Borrower or the right of any Lender provided in Section 2.10, 3.5 or 5.4.

2.13      Notice of Certain Costs. Notwithstanding anything in this Agreement to the contrary, to the extent any notice required by Section 2.10, 2.11, 3.5 or 5.4 is given by any Lender more than 180 days after such Lender has knowledge (or should have had knowledge) of the occurrence of the event giving rise to the additional cost, reduction in amounts, loss, tax or other additional amounts described in such Sections, such Lender shall not be entitled to compensation under Section 2.10, 2.11, 3.5 or 5.4, as the case may be, for any such amounts incurred or accruing prior to the 181st day prior to the giving of such notice to the Borrower; provided that if the circumstance giving rise to such claim is retroactive, then such 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

2.14      Borrowing Base.

(a)        Initial Borrowing Base. For the period from and including the Closing Date to but excluding the first Redetermination Date, the amount of the Borrowing Base shall be $3,973,000 and, subject to Section 6.16 will increase to an amount to be mutually agreed among the Borrower, the Administrative Agent and each of the Lenders. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from time to time pursuant to Section 2.14(e), (f), (g), (h), and (i).

(b)        Scheduled and Interim Redeterminations. The Borrowing Base shall be redetermined semi-annually in accordance with this Section 2.14 (a “Scheduled Redetermination”), and, subject to Section 2.14(d), such redetermined Borrowing Base shall become effective and applicable to the Borrower, the Administrative Agent, the Letter of Credit Issuers and the Lenders on April 15th and October 15th of each year, commencing April 15, 2011. In addition, the Borrower may, by notifying the Administrative Agent thereof one time during any period of 12 consecutive calendar months, and the Administrative Agent may, at the direction of the Required Lenders, by notifying the Borrower thereof, one time during any period of 12 consecutive calendar months, in each case elect to cause the Borrowing Base to be redetermined between Scheduled Redeterminations (an “Interim Redetermination”) in accordance with this Section 2.14. In addition to, and not including and/or limited by the annual Interim Redetermination allowed above, the Borrower may, by notifying the Administrative Agent thereof, at any time between Scheduled Redeterminations, request additional Interim Redeterminations of the Borrowing Base in the event it acquires Oil and Gas Properties with Proved Reserves which are to be Borrowing Base Properties having a PV-9 (calculated at the time of acquisition) in excess of 5% of the Borrowing Base in effect immediately prior to such acquisition.

52

(c)        Scheduled and Interim Redetermination Procedure.

(i)            Each Scheduled Redetermination and each Interim Redetermination shall be effectuated as follows: Upon receipt by the Administrative Agent of (A) the Reserve Report and the Reserve Report Certificate, and (B) such other reports, data and supplemental information, including the information provided pursuant to Section 9.14(c), as may, from time to time, be reasonably requested by the Required Lenders (the Reserve Report, such Reserve Report Certificate and such other reports, data and supplemental information being the “Engineering Reports”), the Administrative Agent shall evaluate the information contained in the Engineering Reports and shall in good faith propose a new Borrowing Base (the “Proposed Borrowing Base”) based upon such information and such other information (including the status of title information with respect to the Borrowing Base Properties as described in the Engineering Reports and the existence of any Hedge Agreements or any other Indebtedness) as the Administrative Agent deems appropriate exercising reasonable commercial standards and consistent with its normal and customary oil and gas lending criteria as it exists at the particular time.

(ii)           The Administrative Agent shall notify the Borrower and the Lenders of the Proposed Borrowing Base (the “Proposed Borrowing Base Notice”):

(A)        in the case of a Scheduled Redetermination (1) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Sections 9.14(a) and (c) in a timely manner, then on or before the March 15th and September 15th of such year following the date of delivery or (2) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Sections 9.14(a) and (c) in a timely manner, then promptly after the Administrative Agent has received complete Engineering Reports from the Borrower and has had a reasonable opportunity to determine the Proposed Borrowing Base in accordance with Section 2. 14(c)(i); and

(B)         in the case of an Interim Redetermination, promptly, and in any event, within 15 days after the Administrative Agent has received the required Engineering Reports.

(iii)          Any Proposed Borrowing Base that would increase the Borrowing Base then in effect must be approved or deemed to have been approved by all of the Lenders in each such Lender’s sole discretion and consistent with each such Lender’s normal and customary oil and gas lending criteria as it exists at the particular time as provided in this Section 2. 14(c)(iii)  and any Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect must be approved or be deemed to have been approved by Lenders constituting at least the Required Lenders in each such Lender’s sole discretion and consistent with each such Lender’s normal and customary oil and gas lending criteria as it exists at the particular time as provided in this Section 2. 14(c)(iii). Upon receipt of the Proposed Borrowing Base Notice, each Lender shall have 15 days to agree with the Proposed Borrowing Base or disagree with the Proposed Borrowing Base by proposing an alternate Borrowing Base. If at the end of such 15-day period, any Lender has not communicated its approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be an approval of the Proposed Borrowing Base. If, at

53

the end of such 15-day period, all of the Lenders, in the case of a Proposed Borrowing Base that would increase the Borrowing Base then in effect, or the Required Lenders, in the case of a Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect, have approved or deemed to have approved, as aforesaid, then the Proposed Borrowing Base shall become the new Borrowing Base, effective on the date specified in Section 2.14(d). If, however, at the end of such 15-day period, all of the Lenders or the Required Lenders, as applicable, have not approved or deemed to have approved, as aforesaid, then the Administrative Agent shall poll the Lenders to ascertain the highest Borrowing Base then acceptable to all of the Lenders or a number of Lenders sufficient to constitute the Required Lenders, as applicable, and, so long as such amount does not increase the Borrowing Base then in effect, such amount shall become the new Borrowing Base, effective on the date specified in Section 2.14(d).

(d)        Effectiveness of a Redetermined Borrowing Base. Subject to Section 2.14(j), after a redetermined Borrowing Base is approved or is deemed to have been approved by all of the Lenders or the Required Lenders, as applicable, pursuant to Section 2. 14(c)(iii), the Administrative Agent shall notify the Borrower and the Lenders of the amount of the redetermined Borrowing Base (the “New Borrowing Base Notice”), and such amount shall become the new Borrowing Base, effective and applicable to the Borrower, the Administrative Agent, the Letter of Credit Issuers and the Lenders:

(i)            in the case of a Scheduled Redetermination, (A) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Sections 9.14(a) and (c) in a timely and complete manner, then on the April 15th or October 15th as applicable, following such notice, or (B) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Sections 9.14(a) and (c) in a timely and complete manner, then on the Business Day next succeeding delivery of such New Borrowing Base Notice; and

(ii)           in the case of an Interim Redetermination, on the Business Day next succeeding delivery of such New Borrowing Base Notice.

Subject to Section 2.14(j), such amount shall then become the Borrowing Base until the next Scheduled Redetermination Date, the next Interim Redetermination Date or the next adjustment to the Borrowing Base under Section 2.14(e), (f), (g), (h), (i) and (j) whichever occurs first. Notwithstanding the foregoing, no Scheduled Redetermination or Interim Redetermination shall become effective until the New Borrowing Base Notice related thereto is received by the Borrower.

(e)          Reduction of Borrowing Base Upon Incurrence of Permitted Additional Debt. Upon the issuance or incurrence of any Permitted Additional Debt in accordance with Section 10.1(n) (other than Permitted Additional Debt constituting Permitted Refinancing Indebtedness incurred to Refinance such Indebtedness, but only to the extent that the aggregate principal amount of Permitted Refinancing Indebtedness incurred to Refinance such Indebtedness does not result in an increase in the principal amount thereof above the principal amount originally incurred or issued up to the original principal amount of the Refinanced Debt), the Borrowing Base then in effect shall be reduced by an amount equal to the product of 0.25 multiplied by the stated principal amount of such Permitted Additional Debt (without regard to any original issue

54

discount), and the Borrowing Base as so reduced shall become the new Borrowing Base immediately upon the date of such issuance or incurrence, effective and applicable to the Borrower, the Administrative Agent, the Letter of Credit Issuers and the Lenders on such date until the next redetermination or modification thereof hereunder.

(f)         Reduction of Borrowing Base Upon Termination of Hedge Positions. If the Borrower shall terminate or create any off-setting positions in respect of any commodity hedge positions (whether evidenced by a floor, put or Hedge Agreement) upon which (i) the Lenders relied in determining the Borrowing Base and (ii) the Hedge PV (as calculated at the time of any such termination or creation of off-setting positions) of such terminated and/or offsetting positions (after taking into account any other Hedge Agreement, executed contemporaneously with the taking of such actions) exceeds 5% of the effective Borrowing Base, then the Required Lenders shall have the right to adjust the Borrowing Base in an amount equal to the Borrowing Base value, if any, attributable to such terminated or off-setting hedge positions in the calculation of the then-effective Borrowing Base and (if the Required Lenders in fact make any such adjustment) the Administrative Agent shall promptly notify the Borrower in writing of the Borrowing Base value, if any, attributable to such hedge positions in the calculation of the then-effective Borrowing Base and upon receipt of such notice, the Borrowing Base shall be simultaneously reduced by such amount. For the avoidance of doubt, the parties acknowledge that the Borrowing Base value of a Hedge Agreement may be more or less than the mark-to-market or termination value of such Hedge Agreement.

(g)        Reduction of Borrowing Base Upon Asset Dispositions. If (i) the Borrower or one of the other Credit Parties Disposes of Oil and Gas Properties or Disposes of any Stock or Stock Equivalents in any Restricted Subsidiary or Minority Investment owning Oil and Gas Properties, (ii) such Disposition involves Borrowing Base Properties included in the most recently delivered Reserve Report and (iii) the aggregate PV-9 (calculated at the time of such Disposition) of all such Borrowing Base Properties Disposed of since the later of (A) the last Scheduled Redetermination Date and (B) the last adjustment of the Borrowing Base made pursuant to this Section 2.14(g) exceeds 5% of the then-effective Borrowing Base, then, after the Administrative Agent has received the notice required to be delivered by the Borrower pursuant to Section 10.4(b), no later than two Business Days’ after the date of consummation of any such Disposition, the Required Lenders shall have the right to adjust the Borrowing Base in an amount equal to the Borrowing Base value, if any, attributable to such Disposed of Borrowing Base Properties in the calculation of the then-effective Borrowing Base and, if the Required Lenders in fact make any such adjustment, the Administrative Agent shall promptly notify the Borrower in writing of the Borrowing Base value, if any, attributable to such Disposed of Borrowing Base Properties in the calculation of the then-effective Borrowing Base and upon receipt of such notice, the Borrowing Base shall be simultaneously reduced by such amount.

(h)        Reduction of Borrowing Base Associated with Title Defects or Exceptions. If any title defect or exception requested by the Administrative Agent to be cured pursuant to Section 9.15(b) cannot be cured within the time period specified therein, the Required Lenders shall have the right to adjust the Borrowing Base in an amount equal to the economic value, if any, by which the Borrowing Base value of the affected Borrowing Base Property is diminished due to such title defect or exception and, if the Required Lenders in fact make any such adjustment, the Administrative Agent shall promptly notify the Borrower in writing of economic value by which

55

the Borrowing Base value of the affected Borrowing Base Property is diminished due to such title defect or exception and upon receipt of such notice, the Borrowing Base shall be simultaneously reduced by such amount.

(i)         Reduction of Borrowing Base Associated with Failure to Enter into Hedges. Within 60 days after each of the Closing Date and the date of the closing of the ConocoPhilips Acquisition, Borrower agrees to use its commercially reasonable efforts to enter into commodity hedging contracts for notional volumes equaling at least 50% of the reasonably anticipated projected production from the total proved developed producing oil and gas reserves (with respect to crude and gas volumes only) attributable to the properties on the Closing Date or the closing date of the ConocoPhilips Acquisition, as applicable, of the Credit Parties (each, a “Minimum Hedge”). Each Minimum Hedge shall be for a period of at least thirty-six (36) months. The Borrowing Base will automatically be decreased by $199,000 in the case of Borrower’s failure to enter into the Closing Date Minimum Hedge and by an amount to be mutually agreed among the Borrower, the Administrative Agent and each of the Lenders in the case of Borrower’s failure to enter into the ConocoPhilips Acquisition Minimum Hedge; provided, however, that if Borrower enters into any hedges within 60 days of the Closing Date or the closing date of the ConocoPhilips Acquisition, as applicable, then the automatic decrease will only be in an amount equal to the product of the aforementioned applicable decrease multiplied  by the fraction where the numerator is (A) the amount of the applicable Minimum Hedge minus  (B) the actual hedges entered into, and the denominator is the applicable Minimum Hedge. Borrower agrees to use its commercially reasonable efforts to enter into hedges at fair market prices (as such are adjusted for appropriate liquidity, credit and other charges). However, for the avoidance of doubt, there shall be no downward adjustment to the Borrowing Base as a result of the actual commodity price(s) of such hedges

(j)         Borrower’s Right to Elect Reduced Borrowing Base. Within three Business Days of its receipt of a New Borrowing Base Notice, the Borrower may provide written notice to the Administrative Agent and the Lenders that specifies for the period from the effective date of the New Borrowing Base Notice until the next succeeding Scheduled Redetermination Date, the Borrowing Base will be a lesser amount than the amount set forth in such New Borrowing Base Notice, whereupon such specified lesser amount will become the new Borrowing Base. The Borrower’s notice under this Section 2.14(j) shall be irrevocable, but without prejudice to its rights to initiate Interim Redeterminations.

(k)        Administrative Agent Data. The Administrative Agent hereby agrees to provide, promptly, and in any event within 3 Business Days, following its receipt of a request by the Borrower, an updated Bank Price Deck. Finally, the Administrative Agent and the Lenders agree, upon request, to meet with the Borrower to discuss their evaluation of the reservoir engineering of the Oil and Gas Properties included in the Reserve Report and their respective methodologies for valuing such properties and the other factors considered in calculating the Borrowing Base.

2.15      Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

56

(a)        Commitment Fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender pursuant to Section 4.1(a);

(b)        the Commitment and Total Exposure of such Defaulting Lender shall not be included in determining whether all Lenders, the Majority Lenders or the Required Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 13.1); provided that (i) any waiver, amendment or modification requiring the consent of all Lenders pursuant to Section 13.1 (other than Section 13.1(ix)) or requiring the consent of each affected Lender pursuant to Section 13.1(i) or (viii), shall require the consent of such Defaulting Lender (which for the avoidance of doubt would include any change to the Maturity Date applicable to such Defaulting Lender, decreasing or forgiving any principal or interest due to such Defaulting Lender, any decrease of any interest rate applicable to Loans made by such Defaulting Lender (other than the waiving of post-default interest rates) and any increase in such Defaulting Lender’s Commitment) and (ii) any redetermination, whether an increase, decrease or affirmation, of the Borrowing Base shall occur without the participation of a Defaulting Lender, but the Commitment (i.e., the Commitment Percentage of the Borrowing Base) of a Defaulting Lender may not be increased without the consent of such Defaulting Lender;

(c)        if any Letter of Credit Exposure exists at the time a Lender becomes a Defaulting Lender, then (i) all or any part of such Letter of Credit Exposure of such Defaulting Lender will, subject to the limitation in the first proviso below and subject to the requirement that there is no Default or Event of Default then existing at such time, automatically be reallocated (effective on the day such Lender becomes a Defaulting Lender) among the Non-Defaulting Lenders pro rata in accordance with their respective Commitment Percentages; provided that (A) each Non- Defaulting Lender’s Letter of Credit Exposure may not in any event exceed the Commitment Percentage of the Loan Limit of such Non-Defaulting Lender as in effect at the time of such reallocation and (B) neither such reallocation nor any payment by a Non-Defaulting Lender pursuant thereto will constitute a waiver or release of any claim the Borrower, the Administrative Agent, the Letter of Credit Issuers or any other Lender may have against such Defaulting Lender or cause such Defaulting Lender to be a Non-Defaulting Lender, (ii) to the extent that all or any portion (the “unreallocated portion”) of the Defaulting Lender’s Letter of Credit Exposure cannot, or can only partially, be so reallocated to Non-Defaulting Lenders, whether by reason of the first proviso in Section 2.1 5(c)(i) or otherwise, the Borrower shall within two Business Days following notice by the Administrative Agent Cash Collateralize such Defaulting Lender’s Letter of Credit Exposure (after giving effect to any partial reallocation pursuant to clause (i) above), in accordance with the procedures set forth in Section 3.8 for so long as such Letter of Credit Exposure is outstanding, (iii) if the Borrower Cash Collateralizes any portion of such Defaulting Lender’s Letter of Credit Exposure pursuant to Section 2.15(c), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 4.1(b) with respect to such Defaulting Lender’s Letter of Credit Exposure during the period such Defaulting Lender’s Letter of Credit Exposure is Cash Collateralized, (iv) if the Letter of Credit Exposure of the non- Defaulting Lenders is reallocated pursuant to Section 2.15(c), then the Letter of Credit Fees payable for the account of the Lenders pursuant to Section 4.1(b) shall be adjusted in accordance with such non-Defaulting Lenders’ Commitment Percentages and the Borrower shall not be required to pay any Letter of Credit Fees to the Defaulting Lender pursuant to Section 4.1(b)  with respect to such Defaulting Lender’s Letter of Credit Exposure during the period that such

57

Defaulting Lender’s Letter of Credit Exposure is reallocated, or (v) if any Defaulting Lender’s Letter of Credit Exposure is neither Cash Collateralized nor reallocated pursuant to this Section 2.15(c), then, without prejudice to any rights or remedies of the Letter of Credit Issuer or any Lender hereunder, all Letter of Credit Fees payable under Section 4.1(b) with respect to such Defaulting Lender’s Letter of Credit Exposure shall be payable to the Letter of Credit Issuer until such Letter of Credit Exposure is Cash Collateralized and/or reallocated; and

(d)        the Letter of Credit Issuer will not be required to issue any new Letter of Credit or amend any outstanding Letter of Credit to increase the Stated Amount thereof, alter the drawing terms thereunder or extend the expiry date thereof, unless the Letter of Credit Issuer is reasonably satisfied that any exposure that would result from the exposure to such Defaulting Lender is eliminated or fully covered by the Commitments of the Non-Defaulting Lenders or by Cash Collateralization or a combination thereof in accordance with clause (c) above or otherwise in a manner reasonably satisfactory to the Letter of Credit Issuer.

(e)        If the Borrower, the Administrative Agent and the Letter of Credit Issuer agree in writing in their discretion that a Lender that is a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon, as of the effective date specified in such notice and subject to any conditions set forth therein, such Lender will cease to be a Defaulting Lender and will be a Non-Defaulting Lender and any applicable Cash Collateral shall be promptly returned to the Borrower and any Letter of Credit Exposure of such Lender reallocated pursuant to Section 2.15(c) shall be reallocated back to such Lender; provided that, except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender.

2.16      Increase of Total Commitment.

(a)        Subject to the conditions set forth in Section 2.16(b), the Borrower may increase the Total Commitment then in effect with the prior written consent of the Administrative Agent by increasing the Commitment of a Lender or by causing a Person that at such time is not a Lender to become a Lender (an “Additional Lender”).

(b)        Any increase in the Total Commitment shall be subject to the following additional conditions:

(i)            such increase shall not be less than $1,987,000 unless the Administrative Agent otherwise consents, and no such increase shall be permitted if after giving effect thereto the Total Commitment would exceed $198,675,000.

(ii)           no Default shall have occurred and be continuing at the effective date of such increase;

(iii)          if, on the effective date of such increase, any LIBOR Loans are outstanding, then the Borrower pays compensation required by Section 2.11;

58

(iv)          no Lender’s Commitment may be increased without the consent of such Lender;

(v)           the Administrative Agent and the Letter of Credit Issuer must consent to the addition of any Additional Lender, such consent not to be unreasonably withheld or delayed;

(vi)          the maturity date of such increase shall be the same as the Maturity Date; and

(vii)         the increase shall be on the exact same terms and pursuant to the exact same documentation applicable to this Agreement.

(c)        Any increase in the Total Commitment shall be implemented using customary documentation.

SECTION 3.       Letters of Credit

3.1        Letters of Credit.

(a)        Subject to and upon the terms and conditions herein set forth, at any time and from time to time on and after the Closing Date and prior to the L/C Maturity Date, the Letter of Credit Issuer agrees, in reliance upon the agreements of the Lenders set forth in this Section 3, to issue upon the request of the Borrower and for the direct or indirect benefit of the Borrower and the Restricted Subsidiaries, a letter of credit or letters of credit (the “Letters of Credit” and each, a “Letter of Credit”) in such form and with such Issuer Documents as may be approved by the Letter of Credit Issuer in its reasonable discretion; provided that the Borrower shall be a co-applicant of, and jointly and severally liable with respect to, each Letter of Credit issued for the account of a Restricted Subsidiary.

(b)        Notwithstanding the foregoing, (i) no Letter of Credit shall be issued the Stated Amount of which, when added to the Letters of Credit Outstanding at such time, would exceed the Letter of Credit Commitment then in effect, (ii) no Letter of Credit shall be issued the Stated Amount of which would cause the aggregate amount of all Lenders’ Total Exposures at such time to exceed the Loan Limit then in effect, (iii) each Letter of Credit shall have an expiration date occurring no later than one year after the date of issuance or such longer period of time as may be agreed by the applicable Issuing Lender, unless otherwise agreed upon by the Administrative Agent and the Letter of Credit Issuer or as provided under Section 3.2(b); provided that any Letter of Credit may provide for automatic renewal thereof for additional periods of up to 12 months or such longer period of time as may be agreed by the applicable Letter of Credit Issuer, subject to the provisions of Section 3.2(b); provided, further, that in no event shall such expiration date occur later than the L/C Maturity Date unless arrangements which are reasonably satisfactory to the Letter of Credit Issuer to Cash Collateralize (or backstop) such Letter of Credit have been made, (iv) each Letter of Credit shall be denominated in Dollars, (v) no Letter of Credit shall be issued if it would be illegal under any applicable Requirement of Law for the beneficiary of the Letter of Credit to have a Letter of Credit issued in its favor and (vi) no Letter of Credit shall be issued by a Letter of Credit Issuer after it has received a written notice from any Credit Party or the Administrative Agent or the Majority Lenders stating that a Default or Event of Default has occurred and is continuing until such time

59

as the Letter of Credit Issuer shall have received a written notice (A) of rescission of such notice from the party or parties originally delivering such notice, (B) of the waiver of such Default or Event of Default in accordance with the provisions of Section 13.1 or (C) that such Default or Event of Default is no longer continuing.

(c)        Upon at least one Business Day’s prior written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent and the Letter of Credit Issuer (which notice the Administrative Agent shall promptly transmit to each of the applicable Lenders), the Borrower shall have the right, on any day, permanently to terminate or reduce the Letter of Credit Commitment in whole or in part; provided that, after giving effect to such termination or reduction, the Letters of Credit Outstanding shall not exceed the Letter of Credit Commitment.

3.2        Letter of Credit Requests.

(a)        Whenever the Borrower desires that a Letter of Credit be issued for its account, the Borrower shall give the Administrative Agent and the Letter of Credit Issuer a Letter of Credit Request by no later than 1:00 p.m. at least two (or such lesser number as may be agreed upon by the Administrative Agent and the Letter of Credit Issuer) Business Days prior to the proposed date of issuance. Each notice shall be executed by the Borrower and shall be in the form of Exhibit C or such other form (including by electronic or fax transmission) as reasonably agreed between the Borrower, the Administrative Agent and the Letter of Credit Issuer (each a “Letter of Credit Request”). No Letter of Credit Issuer shall issue any Letters of Credit unless such Letter of Credit Issuer shall have received notice from the Administrative Agent that the conditions to such issuance have been met, which notice shall be deemed given (i) if the Letter of Credit Issuer has not received notice from the Administrative Agent that the conditions to such issuance have been met within two Business Days after the date of the applicable Letter of Credit Request or (ii) if the aggregate amount of Letters of Credit Outstanding issued by such Letter of Credit Issuer then outstanding does not exceed the amount theretofore agreed to by the Borrower, the Administrative Agent and such Letter of Credit Issuer, and the Administrative Agent has not otherwise notified such Letter of Credit Issuer that it may no longer rely on this clause (i).

(b)        If the Borrower so requests in any applicable Letter of Credit Request, the Letter of Credit Issuer may, in its sole and absolute discretion, agree to issue a Letter of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit the Letter of Credit Issuer to prevent any such extension at least once in each 12-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Non- Extension Notice Date”) in each such 12-month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by the Letter of Credit Issuer, the Borrower shall not be required to make a specific request to the Letter of Credit Issuer for any such extension. Once an Auto-Extension Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) the Letter of Credit Issuer to permit the extension of such Letter of Credit at any time to an expiry date not later than the L/C Maturity Date; provided, however, that the Letter of Credit Issuer shall not permit any such extension if (i) the Letter of Credit Issuer has determined that it would not be permitted, or would have no obligation, at such time to

60

issue such Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of clause (b) of Section 3.1 or otherwise), or (ii) it has received notice (which may be by telephone or in writing) on or before the day that is five Business Days before the Non- Extension Notice Date (A) from the Administrative Agent that the Majority Lenders have elected not to permit such extension or (B) from the Administrative Agent, any Lender or the Borrower that one or more of the applicable conditions specified in Section 7 are not then satisfied, and in each such case directing the Letter of Credit Issuer not to permit such extension.

(c)        Each Letter of Credit Issuer (other than the Administrative Agent or any of its Affiliates) shall, at least once each week, provide the Administrative Agent with a list of all Letters of Credit issued by it that are outstanding at such time; provided that, upon written request from the Administrative Agent, such Letter of Credit Issuer shall thereafter notify the Administrative Agent in writing on each Business Day of all Letters of Credit issued on the prior Business Day by such Letter of Credit Issuer.

(d)        The making of each Letter of Credit Request shall be deemed to be a representation and warranty by the Borrower that the Letter of Credit may be issued in accordance with, and will not violate the requirements of, Section 3.1(b).

3.3        Letter of Credit Participations.

(a)        Immediately upon the issuance by the Letter of Credit Issuer of any Letter of Credit, the Letter of Credit Issuer shall be deemed to have sold and transferred to each Lender (each such Lender, in its capacity under this Section 3.3, an “L/C Participant”), and each such L/C Participant shall be deemed irrevocably and unconditionally to have purchased and received from the Letter of Credit Issuer, without recourse or warranty, an undivided interest and participation (each an “L/C Participation”), to the extent of such L/C Participant’s Commitment Percentage, in each Letter of Credit, each substitute therefor, each drawing made thereunder and the obligations of the Borrower under this Agreement with respect thereto, and any security therefor or guaranty pertaining thereto.

(b)        In determining whether to pay under any Letter of Credit, the relevant Letter of Credit Issuer shall have no obligation relative to the L/C Participants other than to confirm that (i) any documents required to be delivered under such Letter of Credit have been delivered, (ii) the Letter of Credit Issuer has examined the documents with reasonable care and (iii) the documents appear to comply on their face with the requirements of such Letter of Credit. Any action taken or omitted to be taken by the relevant Letter of Credit Issuer under or in connection with any Letter of Credit issued by it, if taken or omitted in the absence of gross negligence or willful misconduct, shall not create for the Letter of Credit Issuer any resulting liability.

(c)        In the event that the Letter of Credit Issuer makes any payment under any Letter of Credit issued by it and the Borrower shall not have repaid such amount in full to the respective Letter of Credit Issuer pursuant to Section 3.4(a), the Letter of Credit Issuer shall promptly notify the Administrative Agent and each L/C Participant of such failure, and each such L/C Participant shall promptly and unconditionally pay to the Administrative Agent for the account of the Letter of Credit Issuer, the amount of such L/C Participant’s Commitment Percentage of such unreimbursed payment in Dollars and in immediately available funds; provided, however, that no

61

L/C Participant shall be obligated to pay to the Administrative Agent for the account of the Letter of Credit Issuer its Commitment Percentage of such unreimbursed amount arising from any wrongful payment made by the Letter of Credit Issuer under any such Letter of Credit as a result of acts or omissions constituting willful misconduct or gross negligence on the part of the Letter of Credit Issuer. Each L/C Participant shall make available to the Administrative Agent for the account of the Letter of Credit Issuer such L/C Participant’s Commitment Percentage of the amount of such payment no later than 1:00 p.m. on the first Business Day after the date notified by the Letter of Credit Issuer in immediately available funds. If and to the extent such L/C Participant shall not have so made its Commitment Percentage of the amount of such payment available to the Administrative Agent for the account of the Letter of Credit Issuer, such L/C Participant agrees to pay to the Administrative Agent for the account of the Letter of Credit Issuer, forthwith on demand, such amount, together with interest thereon for each day from such date until the date such amount is paid to the Administrative Agent for the account of the Letter of Credit Issuer at a rate per annum equal to the Overnight Rate from time to time then in effect, plus any administrative, processing or similar fees customarily charged by the Letter of Credit Issuer in connection with the foregoing. The failure of any L/C Participant to make available to the Administrative Agent for the account of the Letter of Credit Issuer its Commitment Percentage of any payment under any Letter of Credit shall not relieve any other L/C Participant of its obligation hereunder to make available to the Administrative Agent for the account of the Letter of Credit Issuer its Commitment Percentage of any payment under such Letter of Credit on the date required, as specified above, but no L/C Participant shall be responsible for the failure of any other L/C Participant to make available to the Administrative Agent such other L/C Participant’s Commitment Percentage of any such payment.

(d)        Whenever the Letter of Credit Issuer receives a payment in respect of an unpaid reimbursement obligation as to which the Administrative Agent has received for the account of the Letter of Credit Issuer any payments from the L/C Participants pursuant to clause (c) above, the Letter of Credit Issuer shall pay to the Administrative Agent and the Administrative Agent shall promptly pay to each L/C Participant that has paid its Commitment Percentage of such reimbursement obligation, in Dollars and in immediately available funds, an amount equal to such L/C Participant’s share (based upon the proportionate aggregate amount originally funded by such L/C Participant to the aggregate amount funded by all L/C Participants) of the principal amount so paid in respect of such reimbursement obligation and interest thereon accruing after the purchase of the respective L/C Participations at the Overnight Rate.

(e)        The obligations of the L/C Participants to make payments to the Administrative Agent for the account of a Letter of Credit Issuer with respect to Letters of Credit shall be irrevocable and not subject to counterclaim, set-off or other defense or any other qualification or exception whatsoever and shall be made in accordance with the terms and conditions of this Agreement under all circumstances, including under any of the following circumstances:

(i)            any lack of validity or enforceability of this Agreement or any of the other Credit Documents;

(ii)           the existence of any claim, set-off, defense or other right that the Borrower may have at any time against a beneficiary named in a Letter of Credit, any transferee of any Letter of Credit (or any Person for whom any such transferee may be acting), the Administrative

62

Agent, the Letter of Credit Issuer, any Lender or other Person, whether in connection with this Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated transactions (including any underlying transaction between the Borrower and the beneficiary named in any such Letter of Credit);

(iii)       any draft, certificate or any other document presented under any 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;

(iv)       the surrender or impairment of any security for the performance or observance of any of the terms of any of the Credit Documents; or

(v)        the occurrence of any Default or Event of Default;

provided, however, that no L/C Participant shall be obligated to pay to the Administrative Agent for the account of the Letter of Credit Issuer its Commitment Percentage of any unreimbursed amount arising from any wrongful payment made by the Letter of Credit Issuer under a Letter of Credit as a result of acts or omissions constituting willful misconduct or gross negligence on the part of the Letter of Credit Issuer.

3.4        Agreement to Repay Letter of Credit Drawings.

(a)        The Borrower hereby agrees to reimburse the Letter of Credit Issuer, by making payment in Dollars to the Administrative Agent in immediately available funds, for any payment or disbursement made by the Letter of Credit Issuer under any Letter of Credit (each such amount so paid until reimbursed, an “Unpaid Drawing”) (i) within one Business Day after the date on which such payment or disbursement is made, if the Letter of Credit Issuer provides notice to the Borrower of such payment or disbursement prior to 10:00 a.m. on the next succeeding Business Day of such payment or disbursement or (ii) if such notice is received after such time, on the next Business Day following the date of receipt of such notice (such required date for reimbursement under clause (i) or (ii), as applicable, the “Reimbursement Date”), with interest on the amount so paid or disbursed by the Letter of Credit Issuer, to the extent not reimbursed prior to 5:00 p.m. on the Reimbursement Date, from the Reimbursement Date to the date the Letter of Credit Issuer is reimbursed therefor at a rate per annum that shall at all times be the Applicable Margin plus the ABR as in effect from time to time; provided that, notwithstanding anything contained in this Agreement to the contrary, (i) unless the Borrower shall have notified the Administrative Agent and the relevant Letter of Credit Issuer prior to 10:00 a.m. on the Reimbursement Date that the Borrower intends to reimburse the relevant Letter of Credit Issuer for the amount of such drawing with funds other than the proceeds of Loans, the Borrower shall be deemed to have given a Notice of Borrowing requesting that, with respect to Letters of Credit, the Lenders make Loans (which shall be ABR Loans) on the Reimbursement Date in the amount of such drawing and (ii) the Administrative Agent shall promptly notify each Lender of such drawing and the amount of its Loan to be made in respect thereof, and each L/C Participant shall be irrevocably obligated to make a Loan to the Borrower in the manner deemed to have been requested in the amount of its Commitment Percentage of the applicable Unpaid Drawing by 1:00 p.m. on such Reimbursement Date by making the amount of such Loan available to the Administrative Agent. Such Loans shall be made without regard to the

63

Minimum Borrowing Amount. The Administrative Agent shall use the proceeds of such Loans solely for purpose of reimbursing the Letter of Credit Issuer for the related Unpaid Drawing. In the event that the Borrower fails to Cash Collateralize any Letter of Credit that is outstanding on the Maturity Date, the full amount of the Letters of Credit Outstanding in respect of such Letter of Credit shall be deemed to be an Unpaid Drawing subject to the provisions of this Section 3.4 except that the Letter of Credit Issuer shall hold the proceeds received from the Lenders as contemplated above as cash collateral for such Letter of Credit to reimburse any Drawing under such Letter of Credit and shall use such proceeds first, to reimburse itself for any Drawings made in respect of such Letter of Credit following the L/C Maturity Date, second, to the extent such Letter of Credit expires or is returned undrawn while any such cash collateral remains, to the repayment of obligations in respect of any Loans that have not paid at such time and third, to the Borrower or as otherwise directed by a court of competent jurisdiction. Nothing in this Section 3.4(a) shall affect the Borrower’s obligation to repay all outstanding Loans when due in accordance with the terms of this Agreement.

(b)        The obligations of the Borrower under this Section 3.4 to reimburse the Letter of Credit Issuer with respect to Unpaid Drawings (including, in each case, interest thereon) shall be absolute and unconditional under any and all circumstances and irrespective of any set-off, counterclaim or defense to payment that the Borrower or any other Person may have or have had against the Letter of Credit Issuer, the Administrative Agent or any Lender (including in its capacity as an L/C Participant), including any defense based upon the failure of any drawing under a Letter of Credit (each a “Drawing”) to conform to the terms of the Letter of Credit or any non-application or misapplication by the beneficiary of the proceeds of such Drawing; provided that the Borrower shall not be obligated to reimburse the Letter of Credit Issuer for any wrongful payment made by the Letter of Credit Issuer under the Letter of Credit issued by it as a result of acts or omissions constituting willful misconduct or gross negligence on the part of the Letter of Credit Issuer.

3.5        Increased Costs. If, after the Closing Date, the adoption of any Change in Law shall either (a) impose, modify or make applicable any reserve, deposit, capital adequacy or similar requirement against letters of credit issued by the Letter of Credit Issuer, or any L/C Participant’s L/C Participation therein, or (b) impose on the Letter of Credit Issuer or any L/C Participant any other conditions affecting its obligations under this Agreement in respect of Letters of Credit or L/C Participations therein or any Letter of Credit or such L/C Participant’s L/C Participation therein, and the result of any of the foregoing is to increase the cost to the Letter of Credit Issuer or such L/C Participant of issuing, maintaining or participating in any Letter of Credit, or to reduce the amount of any sum received or receivable by the Letter of Credit Issuer or such L/C Participant hereunder (other than any such increase or reduction attributable to (i) taxes indemnified under Section 5.4, (ii) net income taxes and franchise and excise taxes (imposed in lieu of net income taxes) imposed on any Agent or Lender or (iii) Taxes included under clauses (c), (d) and (e) of the definition of “Excluded Taxes”) in respect of Letters of Credit or L/C Participations therein, then, promptly (and in any event no later than 15 days) after receipt of written demand to the Borrower by the Letter of Credit Issuer or such L/C Participant, as the case may be (a copy of which notice shall be sent by the Letter of Credit Issuer or such L/C Participant to the Administrative Agent), the Borrower shall pay to the Letter of Credit Issuer or such L/C Participant such additional amount or amounts as will compensate the Letter of Credit Issuer or such L/C Participant for such increased cost or reduction, it being

64

understood and agreed, however, that the Letter of Credit Issuer or an L/C Participant shall not be entitled to such compensation as a result of such Person’s compliance with, or pursuant to any request or directive to comply with, any such Requirement of Law as in effect on the Closing Date. A certificate submitted to the Borrower by the relevant Letter of Credit Issuer or an L/C Participant, as the case may be (a copy of which certificate shall be sent by the Letter of Credit Issuer or such L/C Participant to the Administrative Agent), setting forth in reasonable detail the basis for the determination of such additional amount or amounts necessary to compensate the Letter of Credit Issuer or such L/C Participant as aforesaid shall be conclusive and binding on the Borrower absent clearly demonstrable error.

3.6         New or Successor Letter of Credit Issuer.

(a)          The Letter of Credit Issuer may resign as a Letter of Credit Issuer upon 30 days’ prior written notice to the Administrative Agent, the Lenders and the Borrower. The Borrower may replace the Letter of Credit Issuer for any reason upon written notice to the Letter of Credit Issuer and the Administrative Agent and may add Letter of Credit Issuers at any time upon notice to the Administrative Agent. If the Letter of Credit Issuer shall resign or be replaced, or if the Borrower shall decide to add a new Letter of Credit Issuer under this Agreement, then the Borrower may appoint from among the Lenders a successor issuer of Letters of Credit or a new Letter of Credit Issuer, as the case may be, or, with the consent of the Administrative Agent (such consent not to be unreasonably withheld), another successor or new issuer of Letters of Credit, whereupon such successor issuer shall succeed to the rights, powers and duties of the replaced or resigning Letter of Credit Issuer under this Agreement and the other Credit Documents, or such new issuer of Letters of Credit shall be granted the rights, powers and duties of a Letter of Credit Issuer hereunder, and the term “Letter of Credit Issuer” shall mean such successor or such new issuer of Letters of Credit effective upon such appointment. The acceptance of any appointment as a Letter of Credit Issuer hereunder whether as a successor issuer or new issuer of Letters of Credit in accordance with this Agreement, shall be evidenced by an agreement entered into by such new or successor issuer of Letters of Credit, in a form reasonably satisfactory to the Borrower and the Administrative Agent and, from and after the effective date of such agreement, such new or successor issuer of Letters of Credit shall become a “Letter of Credit Issuer” hereunder. After the resignation or replacement of a Letter of Credit Issuer hereunder, the resigning or replaced Letter of Credit Issuer shall remain a party hereto and shall continue to have all the rights and obligations of a Letter of Credit Issuer under this Agreement and the other Credit Documents with respect to Letters of Credit issued by it prior to such resignation or replacement, but shall not be required to issue additional Letters of Credit. In connection with any resignation or replacement pursuant to this clause (a) (but, in case of any such resignation, only to the extent that a successor issuer of Letters of Credit shall have been appointed), either (i) the Borrower, the resigning or replaced Letter of Credit Issuer and the successor issuer of Letters of Credit shall arrange to have any outstanding Letters of Credit issued by the resigning or replaced Letter of Credit Issuer replaced with Letters of Credit issued by the successor issuer of Letters of Credit or (ii) the Borrower shall cause the successor issuer of Letters of Credit, if such successor issuer is reasonably satisfactory to the replaced or resigning Letter of Credit Issuer, to issue “back-stop” Letters of Credit naming the resigning or replaced Letter of Credit Issuer as beneficiary for each outstanding Letter of Credit issued by the resigning or replaced Letter of Credit Issuer, which new Letters of Credit shall have a Stated Amount equal to the Letters of Credit being back-stopped and the sole requirement for drawing

65

on such new Letters of Credit shall be a drawing on the corresponding back-stopped Letters of Credit. After any resigning or replaced Letter of Credit Issuer’s resignation or replacement as Letter of Credit Issuer, the provisions of this Agreement relating to a Letter of Credit Issuer shall inure to its benefit as to any actions taken or omitted to be taken by it (A) while it was a Letter of Credit Issuer under this Agreement or (B) at any time with respect to Letters of Credit issued by such Letter of Credit Issuer.

(b)        To the extent that there are, at the time of any resignation or replacement as set forth in clause (a) above, any outstanding Letters of Credit, nothing herein shall be deemed to impact or impair any rights and obligations of any of the parties hereto with respect to such outstanding Letters of Credit (including any obligations related to the payment of fees or the reimbursement or funding of amounts drawn), except that the Borrower, the resigning or replaced Letter of Credit Issuer and the successor issuer of Letters of Credit shall have the obligations regarding outstanding Letters of Credit described in clause (a) above.

3.7        Role of Letter of Credit Issuer. Each Lender and the Borrower agree that, in paying any drawing under a Letter of Credit, the Letter of Credit Issuer shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. None of the Letter of Credit Issuer, the Administrative Agent, any of their respective affiliates nor any correspondent, participant or assignee of the Letter of Credit Issuer shall be liable to any Lender for (a) any action taken or omitted in connection herewith at the request or with the approval of the Majority Lenders, (b) any action taken or omitted in the absence of gross negligence or willful misconduct or (c) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Issuer Document. The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided that this assumption is not intended to, and shall not, preclude the Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of the Letter of Credit Issuer, the Administrative Agent, any of their respective affiliates nor any correspondent, participant or assignee of the Letter of Credit Issuer shall be liable or responsible for any of the matters described in Section 3.3(e); provided that anything in such Section to the contrary notwithstanding, the Borrower may have a claim against the Letter of Credit Issuer, and the Letter of Credit Issuer may be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by the Borrower which the Borrower proves were caused by the Letter of Credit Issuer’s willful misconduct or gross negligence or the Letter of Credit Issuer’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and not in limitation of the foregoing, the Letter of Credit Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and the Letter of Credit Issuer shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

3.8         Cash Collateral.

(a)          Upon the request of the Majority Lenders if, as of the L/C Maturity Date, there are any Letters of Credit Outstanding, the Borrower shall immediately Cash Collateralize the then Letters of Credit Outstanding.

(b)        If any Event of Default shall occur and be continuing, the Majority Lenders may require that the L/C Obligations be Cash Collateralized; provided that, upon the occurrence of an Event of Default referred to in Section 11.5 with respect to the Borrower, the Borrower shall immediately Cash Collateralize the Letters of Credit then outstanding and no notice or request by or consent from the Majority Lenders shall be required.

(c)        For purposes of this Agreement, “Cash Collateralize” shall mean to pledge and deposit with or deliver to the Administrative Agent, for the benefit of the Letter of Credit Issuer and the Lenders, as collateral for the L/C Obligations, cash or deposit account balances in an amount equal to the amount of the Letters of Credit Outstanding required to be Cash Collateralized pursuant to documentation in form and substance reasonably satisfactory to the Administrative Agent and the Letter of Credit Issuer (which documents are hereby consented to by the Lenders). Derivatives of such term have corresponding meanings. The Borrower hereby grants to the Administrative Agent, for the benefit of the Letter of Credit Issuer and the L/C Participants, a security interest in all such cash, deposit accounts and all balances therein and all proceeds of the foregoing. Such cash Collateral shall be maintained in blocked, interest bearing deposit accounts established by and in the name of the Borrower, but under the “control” (as defined in Section 9-104 of the UCC) of the Administrative Agent.

3.9        Applicability of ISP and UCP. Unless otherwise expressly agreed by the Letter of Credit Issuer and the Borrower when a Letter of Credit is issued, (a) the rules of the ISP shall apply to each standby Letter of Credit and (b) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce at the time of issuance, shall apply to each commercial Letter of Credit.

3.10       Conflict with Issuer Documents. In the event of any conflict between the terms hereof and the terms of any Issuer Document, the terms hereof shall control.

3.11       Letters of Credit Issued for Restricted Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Restricted Subsidiary, the Borrower shall be obligated to reimburse the Letter of Credit Issuer hereunder for any and all drawings under such Letter of Credit. The Borrower hereby acknowledges that the issuance of Letters of Credit for the account of Restricted Subsidiaries inures to the benefit of the Borrower, and that the Borrower’s business derives substantial benefits from the businesses of such Restricted Subsidiaries.

SECTION 4.         Fees; Commitments

4.1         Fees.

(a)          The Borrower agrees to pay to the Administrative Agent in Dollars, for the account of each Lender (in each case pro rata according to the respective Commitment

67

Percentages of the Lenders), a commitment fee (the “Commitment Fee”) for each day from the Closing Date until the Termination Date. Each Commitment Fee shall be payable by the Borrower (i) quarterly in arrears on the last Business Day of each March, June, September and December (for the three-month period (or portion thereof) ended on such day for which no payment has been received) and (ii) on the Termination Date (for the period ended on such date for which no payment has been received pursuant to clause (i) above), and shall be computed for each day during such period at a rate per annum equal to the Commitment Fee Rate in effect on such day on the Available Commitment in effect on such day.

(b)        The Borrower agrees to pay to the Administrative Agent in Dollars for the account of the Lenders pro rata on the basis of their respective Letter of Credit Exposure, a fee in respect of each Letter of Credit (the “Letter of Credit Fee”), for the period from the date of issuance of such Letter of Credit until the termination or expiration date of such Letter of Credit computed at the per annum rate for each day equal to the Applicable Margin for LIBOR Loans on the average daily Stated Amount of such Letter of Credit. Such Letter of Credit Fees shall be due and payable (i) quarterly in arrears on the last Business Day of each March, June, September and December and (ii) on the Termination Date (for the period for which no payment has been received pursuant to clause (i) above).

(c)        The Borrower agrees to pay to each Letter of Credit Issuer a fee in respect of each Letter of Credit issued by it (the “Fronting Fee”), for the period from the date of issuance of such Letter of Credit to the termination or expiration date of such Letter of Credit, computed at the rate for each day equal to 0.25% per annum on the average daily Stated Amount of such Letter of Credit (or at such other rate per annum as agreed in writing between the Borrower and the Letter of Credit Issuer); provided that in no event shall the Fronting Fee for any Letter of Credit be less than $125 per quarter. Such Fronting Fees shall be due and payable by the Borrower (i) quarterly in arrears on the last Business Day of each March, June, September and December and (ii) on the Termination Date (for the period for which no payment has been received pursuant to clause (i) above).

(d)        The Borrower agrees to pay directly to the Letter of Credit Issuer upon each issuance of, drawing under, and/or amendment of, a Letter of Credit issued by it such amount as the Letter of Credit Issuer and the Borrower shall have agreed upon for issuances of, drawings under or amendments of, letters of credit issued by it.

4.2         Voluntary Reduction of Commitments.

(a)          Upon at least two Business Days’ prior written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent at the Administrative Agent’s Office (which notice the Administrative Agent shall promptly transmit to each of the Lenders), the Borrower shall have the right, without premium or penalty, on any day, permanently to terminate or reduce the Commitments in whole or in part; provided that (i) any such reduction shall apply proportionately and permanently to reduce the Commitments of each of the Lenders, (ii) any partial reduction pursuant to this Section 4.2 shall be in the amount of at least $1,000,000 and in multiples of $100,000 in excess thereof and (iii) after giving effect to such termination or reduction and to any prepayments of the Loans made on the date thereof in accordance with this

68

Agreement (including pursuant to Section 5.2(a)), the aggregate amount of all Lenders’ Total Exposures shall not exceed the Loan Limit.

(b)        The Borrower may at any time terminate the Total Commitment upon (i) the payment in full of all outstanding Loans, together with accrued and unpaid interest thereon, (ii) the cancellation and return of all outstanding Letters of Credit (or alternatively, with respect to each such Letter of Credit, the Cash Collateralization thereof), (iii) the payment in full of the accrued and unpaid fees, including any payments required under Section 2.11, as applicable, and (iv) the payment in full of all reimbursable expenses and other Obligations (other than Hedge Obligations under Secured Hedge Agreements, Cash Management Obligations under Secured Cash Management Agreements and contingent indemnification obligations not then due and payable) together with accrued and unpaid interest thereon, as applicable.

4.3        Mandatory Termination of Commitments. The Total Commitment shall terminate at 5:00 p.m. on the Termination Date.

4.4        Commitments and Credit Exposures under the Facilities. Each Lender hereby covenants and agrees that, without the prior written consent of each other Lender and, unless an Event of Default has occurred and is continuing, the Borrower, so long as Aggregate Facility Commitments have not been terminated and Aggregate Facility Exposures have not been indefeasibly paid in full in cash, such Lender will at all times have a Commitment and Credit Exposure under this Agreement that represents the same percentage of the aggregate amount of such Lender’s commitments to all of the Facilities (including its Commitment under this Agreement) as the Facility Required Percentage for this Facility at such time. Notwithstanding anything to the contrary contained herein (including, without limitation, Section 13.6), unless such prior written consent of each Lender has been obtained, no Lender shall assign or otherwise transfer any of its rights or obligations hereunder or sell participations in any portion of its rights or obligations hereunder, if after giving effect to any such assignment, transfer or participation, such Lender or the relevant assignee (or Participant, assuming such Participant were a Lender for this purpose) would be in violation of this Section 4.4.

SECTION 5.         Payments

5.1         Voluntary Prepayments. The Borrower shall have the right to prepay Loans, without premium or penalty, in whole or in part from time to time on the following terms and conditions:

(a)        the Borrower shall give the Administrative Agent at the Administrative Agent’s Office written notice (or telephonic notice promptly confirmed in writing) of its intent to make such prepayment, the amount of such prepayment and (in the case of LIBOR Loans) the specific Borrowing(s) being prepaid, which notice shall be given by the Borrower no later than 1:00 p.m. (i) in the case of LIBOR Loans, three Business Days prior to and (ii) in the case of ABR Loans on the date of such prepayment and shall promptly be transmitted by the Administrative Agent to each of the Lenders;

(b)        each partial prepayment of (i) LIBOR Loans shall be in a minimum amount of $500,000 and in multiples of $100,000 in excess thereof, and (ii) any ABR Loans shall be in a

69

minimum amount of $500,000 and in multiples of $100,000 in excess thereof; provided that no partial prepayment of LIBOR Loans made pursuant to a single Borrowing shall reduce the outstanding LIBOR Loans made pursuant to such Borrowing to an amount less than the applicable Minimum Borrowing Amount for such LIBOR Loans; and

(c)        any prepayment of LIBOR Loans pursuant to this Section 5.1 on any day other than the last day of an Interest Period applicable thereto shall be subject to compliance by the Borrower with the applicable provisions of Section 2.11.

Each such notice shall specify the date and amount of such prepayment and the Type of Loans to be prepaid. At the Borrower’s election in connection with any prepayment pursuant to this Section 5.1, such prepayment shall not be applied to any Loans of a Defaulting Lender.

5.2        Mandatory Prepayments.

(a)        Repayment following Optional Reduction of Commitments. If, after giving effect to any termination or reduction of the Commitments pursuant to Section 4.2(a), the aggregate Total Exposures of all Lenders exceeds the Loan Limit (as reduced), then the Borrower shall on the same Business Day (i) prepay the Loans on the date of such termination or reduction in an aggregate principal amount equal to such excess and (ii) if any excess remains after prepaying all of the Loans as a result of any Letter of Credit Exposure, pay to the Administrative Agent on behalf of the Letter of Credit Issuer and the L/C Participants an amount in cash equal to such excess to be held as cash collateral as provided in Section 3.8.

(b)        Repayment of Loans Following Redetermination or Adjustment of Borrowing Base.

(i)            Upon any redetermination of the Borrowing Base in accordance with Section 2.14(b), if the aggregate Total Exposures of all Lenders exceeds the redetermined Borrowing Base, then the Borrower shall, within 10 Business Days after its receipt of a New Borrowing Base Notice inform the Administrative Agent of the Borrower’s election to: (A) within 30 days following its receipt of such New Borrowing Base Notice (1) prepay the Loans in an aggregate principal amount equal to such excess and (2) if any excess remains after prepaying all of the Loans as a result of any Letter of Credit Exposure, Cash Collateralize such excess as provided in Section 3.8 (provided that all payments required to be made pursuant to this Section 5.2(b)(i) must be made on or prior to the Termination Date), (B) prepay the Loans in six equal monthly installments, commencing on the 30th day following its receipt of such New Borrowing Base Notice with each payment being equal to 1/6th of the aggregate principal amount of such excess (provided that all payments required to be made pursuant to this Section 5.2(b)(i) must be made on or prior to the Termination Date), (C) within 30 days following its receipt of such New Borrowing Base Notice, provide additional collateral in the form of additional Oil and Gas Properties not evaluated in the most recently delivered Reserve Report or other collateral reasonably acceptable to the Administrative Agent having a Borrowing Base value (as proposed by the Administrative Agent and approved by the Required Lenders) sufficient, after giving effect to any other actions taken pursuant to this Section 5.2(b)(i) to eliminate any such excess or (D) undertake a combination of clauses (A), (B) and (C). If, because of Letter of Credit

70

Exposure, a Borrowing Base Deficiency remains after prepaying all of the Loans, the Borrower shall Cash Collateralize such remaining Borrowing Base Deficiency as provided in Section 3.8.

(ii)           Upon any adjustment to the Borrowing Base pursuant to Section 2.14(e), (f), (g), (h) or (i) if the aggregate Total Exposures of all Lenders exceeds the Borrowing Base, as adjusted, then the Borrower shall (A) prepay the Loans in an aggregate principal amount equal to such excess and (B) if any excess remains after prepaying all of the Loans as a result of any Letter of Credit Exposure, Cash Collateralize such excess as provided in Section 3.8. The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral no later than the first Business Day following the date it receives written notice from the Administrative Agent of the adjustment of the Borrowing Base and the resulting Borrowing Base Deficiency; provided that all payments required to be made pursuant to this clause must be made on or prior to the Termination Date.

(c)        Application to Loans. With respect to each prepayment of Loans elected under Section 5.1 or required by Section 5.2, the Borrower may designate (i) the Types of Loans that are to be prepaid and the specific Borrowing(s) being repaid and (ii) the Loans to be prepaid; provided that (A) each prepayment of any Loans made pursuant to a Borrowing shall be applied pro rata among such Loans and (B) notwithstanding the provisions of the preceding clause (A), no prepayment of Loans shall be applied to the Loans of any Defaulting Lender unless otherwise agreed in writing by the Borrower. In the absence of a designation by the Borrower as described in the preceding sentence, the Administrative Agent shall, subject to the above, make such designation in its reasonable discretion with a view, but no obligation, to minimize breakage costs owing under Section 2.11.

(d)        LIBOR Interest Periods. In lieu of making any payment pursuant to this Section 5.2 in respect of any LIBOR Loan, other than on the last day of the Interest Period therefor so long as no Event of Default shall have occurred and be continuing, the Borrower at its option may deposit, on behalf of the Borrower, with the Administrative Agent an amount equal to the amount of the LIBOR Loan to be prepaid and such LIBOR Loan shall be repaid on the last day of the Interest Period therefor in the required amount. Such deposit shall be held by the Administrative Agent in a corporate time deposit account established on terms reasonably satisfactory to the Administrative Agent, earning interest at the then customary rate for accounts of such type. Such deposit shall constitute cash collateral for the LIBOR Loans to be so prepaid; provided that the Borrower may at any time direct that such deposit be applied to make the applicable payment required pursuant to this Section 5.2.

5.3         Method and Place of Payment.

(a)          Except as otherwise specifically provided herein, all payments under this Agreement shall be made by the Borrower without set-off, counterclaim or deduction of any kind, to the Administrative Agent for the ratable account of the Lenders entitled thereto or the Letter of Credit Issuer entitled thereto, as the case may be, not later than 2:00 p.m., in each case, on the date when due and shall be made in immediately available funds at the Administrative Agent’s Office or at such other office as the Administrative Agent shall specify for such purpose by notice to the Borrower; it being understood that written or facsimile notice by the Borrower to the Administrative Agent to make a payment from the funds in the Borrower’s account at the

71

Administrative Agent’s Office shall constitute the making of such payment to the extent of such funds held in such account. All repayments or prepayments of any Loans (whether of principal, interest or otherwise) hereunder and all other payments under each Credit Document shall be made in Dollars. The Administrative Agent will thereafter cause to be distributed on the same day (if payment was actually received by the Administrative Agent prior to 2:00 p.m. or, otherwise, on the next Business Day in the sole discretion of the Administrative Agent) like funds relating to the payment of principal or interest or fees ratably to the Lenders or the Letter of Credit Issuer, as applicable, entitled thereto.

(b)         For purposes of computing interest or fees, any payments under this Agreement that are made later than 2:00 p.m. shall be deemed to have been made on the next succeeding Business Day in the sole discretion of the Administrative Agent. Whenever any payment to be made hereunder shall be stated to be due on a day that is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day and, with respect to payments of principal, interest shall be payable during such extension at the applicable rate in effect immediately prior to such extension.

5.4         Net Payments.

(a)          Any and all payments made by or on behalf of the Borrower or any Guarantor under this Agreement or any other Credit Document shall be made free and clear of, and without deduction or withholding for or on account of, any Indemnified Taxes; provided that if the Borrower or any Guarantor shall be required by applicable Requirements of Law to deduct or withhold any Indemnified Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions and withholdings (including deductions or withholdings applicable to additional sums payable under this Section 5.4) the Administrative Agent, the Collateral Agent, any Letter of Credit Issuer or any Lender, as the case may be, receives an amount equal to the sum it would have received had no such deductions or withholdings been made, (ii) the Borrower or such Guarantor shall make such deductions or withholdings and (iii) the Borrower or such Guarantor shall timely pay the full amount deducted or withheld to the relevant Governmental Authority within the time allowed and in accordance with applicable Requirements of Law. Whenever any Indemnified Taxes are payable by the Borrower or such Guarantor, as promptly as possible thereafter, the Borrower or Guarantor shall send to the Administrative Agent for its own account or for the account of such Letter of Credit Issuer or Lender, as the case may be, a certified copy of an original official receipt (or other evidence acceptable to such Letter of Credit Issuer or Lender, acting reasonably) received by the Borrower or such Guarantor showing payment thereof.

(b)         The Borrower shall timely pay and shall indemnify and hold harmless the Administrative Agent, each Collateral Agent and each Lender (whether or not such Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority) with regard to any Other Taxes.

(c)          The Borrower shall indemnify and hold harmless the Administrative Agent, the Collateral Agent and each Lender within 15 Business Days after written demand therefor, for the full amount of any Indemnified Taxes imposed on the Administrative Agent, the Collateral Agent or such Lender as the case may be, on or with respect to any payment by or on account of

72

any obligation of the Borrower or any Guarantor hereunder or under any other Credit Document (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 5.4) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate setting forth reasonable detail as to the amount of such payment or liability delivered to the Borrower by a Lender, the Administrative Agent or the Collateral Agent (as applicable) on its own behalf or on behalf of a Lender shall be conclusive absent manifest error.

(d)         Any Non-U.S. Lender that is entitled to an exemption from or reduction of any applicable withholding tax with respect to payments under this Agreement or any other Credit Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

(e)          Without limiting the generality of the foregoing, each Non-U.S. Lender with respect to any Loan made to the Borrower shall, to the extent it is legally entitled to do so:

(i)            deliver to the Borrower and the Administrative Agent, prior to the date on which the first payment to the Non-U.S. Lender is due hereunder, two copies of (A) in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest”, United States Internal Revenue Service Form W-8BEN (or any applicable successor form) (together with a certificate representing that such Non-U.S. Lender is not a bank for purposes of Section 88 1(c) of the Code, is not a 10% shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the Borrower, is not a controlled foreign corporation related to the Borrower (within the meaning of Section 864(d)(4) of the Code) and the interest payments in question are not effectively connected with the United States trade or business conducted by such Lender), (B) Internal Revenue Service Form W-8BEN or Form W-8ECI (or any applicable successor form), in each case properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or reduced rate of, U.S. Federal withholding tax on payments by the Borrower under this Agreement, (C) Internal Revenue Service Form W-8IMY (or any applicable successor form) and all necessary attachments (including the forms described in clauses (A) and (B) above, as required) or (D) any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in United States federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower to determine the withholding or deduction required to be made; and

(ii)           deliver to the Borrower and the Administrative Agent two further copies of any such form or certification (or any applicable successor form) on or before the date that

73

any such form or certification expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower;

unless in any such case any Change in Law has occurred prior to the date on which any such delivery would otherwise be required that renders any such form inapplicable or would prevent such Non-U.S. Lender from duly completing and delivering any such form with respect to it and such Non-U.S. Lender promptly so advises the Borrower and the Administrative Agent. Each Person that shall become a Participant pursuant to Section 13.6 or a Lender pursuant to Section 13.6 shall, upon the effectiveness of the related transfer, be required to provide all the forms and statements required pursuant to this Section 5.4(e); provided that in the case of a Participant such Participant shall furnish all such required forms and statements to the Lender from which the related participation shall have been purchased.

(f)         If any Lender, the Administrative Agent or the Collateral Agent, as applicable, determines, in its sole discretion, that it had received and retained a refund of an Indemnified Tax (including an Other Tax) for which a payment has been made by the Borrower pursuant to this Agreement, which refund in the good faith judgment of such Lender, the Administrative Agent or the Collateral Agent, as the case may be, is attributable to such payment made by the Borrower, then the Lender, the Administrative Agent or the Collateral Agent, as the case may be, shall reimburse the Borrower for such amount (net of all out-of-pocket expenses of such Lender, the Administrative Agent or the Collateral Agent, as the case may be, and without interest other than any interest received thereon from the relevant Governmental Authority with respect to such refund) as the Lender, Administrative Agent or the Collateral Agent, as the case may be, determines in its sole discretion to be the proportion of the refund as will leave it, after such reimbursement, in no better or worse position (taking into account expenses or any taxes imposed on the refund) than it would have been in if the payment had not been required; provided that the Borrower, upon the request of the Lender, the Administrative Agent or the Collateral Agent, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Lender, the Administrative Agent or the Collateral Agent in the event the Lender, the Administrative Agent or the Collateral Agent is required to repay such refund to such Governmental Authority. A Lender, the Administrative Agent or the Collateral Agent shall claim any refund that it determines is available to it, unless it concludes in its sole discretion that it would be adversely affected by making such a claim. Neither the Lender, the Administrative Agent nor the Collateral Agent shall be obliged to disclose any information regarding its tax affairs or computations to any Credit Party in connection with this clause (f) or any other provision of this Section 5.4.

(g)        If the Borrower determines that a reasonable basis exists for contesting a Tax, each Lender or Agent, as the case may be, shall use reasonable efforts to cooperate with the Borrower as the Borrower may reasonably request in challenging such Tax. Subject to the provisions of Section 2.12, each Lender and Agent agree to use reasonable efforts to cooperate with the Borrower as the Borrower may reasonably request to minimize any amount payable by the Borrower or any Guarantor pursuant to this Section 5.4. The Borrower shall indemnify and hold each Lender and Agent harmless against any out-of-pocket expenses incurred by such Person in connection with any request made by the Borrower pursuant to this Section 5.4(g).

74

Nothing in this Section 5.4(g) shall obligate any Lender or Agent to take any action that such Person, in its sole judgment, determines may result in a material detriment to such Person.

(h)        Each Lender and Agent with respect to the Loan and any other Loan made to the Borrower that is a United States person under Section 7701(a)(30) of the Code (each, a “U.S. Lender”) shall deliver to the Borrower and the Administrative Agent two United States Internal Revenue Service Forms W-9 (or substitute or successor form), properly completed and duly executed, certifying that such Lender or Agent is exempt from United States backup withholding (i) on or prior to the Closing Date (or on or prior to the date it becomes a party to this Agreement), (ii) on or before the date that such form expires or becomes obsolete, (iii) after the occurrence of a change in the Agent’s or Lender’s circumstances requiring a change in the most recent form previously delivered by it to the Borrower and the Administrative Agent, and (iv) from time to time thereafter if reasonably requested by the Borrower or the Administrative Agent.

(i)         The agreements in this Section 5.4 shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

5.5        Computations of Interest and Fees.

(a)        Except as provided in the next succeeding sentence, Interest on LIBOR Loans and ABR Loans shall be calculated on the basis of a 360-day year for the actual days elapsed. Interest on ABR Loans in respect of which the rate of interest is calculated on the basis of the Administrative Agent’s prime rate and interest on overdue interest shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed.

(b)        Fees and the average daily Stated Amount of Letters of Credit shall be calculated on the basis of a 360-day year for the actual days elapsed.

5.6        Limit on Rate of Interest.

(a)        No Payment Shall Exceed Lawful Rate. Notwithstanding any other term of this Agreement, the Borrower shall not be obligated to pay any interest or other amounts under or in connection with this Agreement or otherwise in respect to any of the Obligations in excess of the amount or rate permitted under or consistent with any applicable law, rule or regulation.

(b)        Payment at Highest Lawful Rate. If the Borrower is not obliged to make a payment that it would otherwise be required to make, as a result of Section 5.6(a), the Borrower shall make such payment to the maximum extent permitted by or consistent with applicable laws, rules and regulations.

(c)        Adjustment if Any Payment Exceeds Lawful Rate. If any provision of this Agreement or any of the other Credit Documents would obligate the Borrower or any other Credit Party to make any payment of interest or other amount payable to any Lender in an amount or calculated at a rate that would be prohibited by any applicable Requirement of Law, then notwithstanding such provision, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by applicable Requirements of Law, such adjustment to be effected, to the

75

extent necessary, by reducing the amount or rate of interest required to be paid by the Borrower to the affected Lender under Section 2.8.

(d)        Rebate of Excess Interest. Notwithstanding the foregoing, and after giving effect to all adjustments contemplated thereby, if any Lender shall have received from the Borrower an amount in excess of the maximum permitted by any applicable Requirement of Law, then the Borrower shall be entitled, by notice in writing to the Administrative Agent to obtain reimbursement from that Lender in an amount equal to such excess, and pending such reimbursement, such amount shall be deemed to be an amount payable by that Lender to the Borrower.

SECTION 6.           Conditions Precedent to Initial Borrowing and to ConocoPhilips Acquisition Increase in Borrowing Base.

The initial Borrowing under this Agreement is subject to the satisfaction of the following conditions precedent (other than the conditions set forth in Section 6.16), except as otherwise agreed or waived pursuant to Section 13.1.

6.1        Credit Documents. The Administrative Agent shall have received:

Each Credit Party has the corporate or other organizational power and authority to execute, deliver and carry out the terms and provisions of the Credit Documents to which it is a party and has taken all necessary corporate or other organizational action to authorize the execution, delivery and performance of the Credit Documents to which it is a party. Each Credit Party has duly executed and delivered each Credit Document to which it is a party and each such Credit Document constitutes the legal, valid and binding obligation of such Credit Party enforceable in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization and other similar laws relating to or affecting creditors’ rights generally and general principles of equity whether considered in a proceeding in equity or law).

8.3        No Violation. None of the execution, delivery or performance by any Credit Party of the Credit Documents to which it is a party, the compliance with the terms and provisions thereof or the consummation of the transactions contemplated hereby or thereby will (a) contravene any applicable provision of any material Requirement of Law, (b) result in any breach of any of the terms, covenants, conditions or provisions of, or constitute a default under, or result in the creation or imposition of (or the obligation to create or impose) any Lien upon any of the property or assets of such Credit Party or any of the Restricted Subsidiaries (other than Liens created under the Credit Documents) pursuant to the terms of any material indenture, loan agreement, lease agreement, mortgage, deed of trust, agreement or other material instrument to which such Credit Party or any of the Restricted Subsidiaries is a party or by which it or any of its property or assets is bound (any such term, covenant, condition or provision, a “Contractual Requirement”) other than any such breach, default or Lien that could not reasonably be expected to result in a Material Adverse Effect or (c) violate any provision of the certificate of incorporation, by-laws or other organizational documents of such Credit Party or any of the Restricted Subsidiaries.

No Plan (other than a Multiemployer Plan) has an Unfunded Current Liability that would, individually or when taken together with any other liabilities referenced in this Section 8.11(a), be reasonably likely to have a Material Adverse Effect.
