This Section shall not apply to Swingline Borrowings, which may not be converted or continued.

(b)                                 Interest Election Requests.  To make an election pursuant to this Section 2.05, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election.  Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or facsimile or other electronic transmission to the Administrative Agent of a written Interest Election Request in substantially the form of Exhibit C and signed by the Borrower.

(c)                                  Information in Interest Election Requests.  Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02:

(i)                                     the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to Section 2.05(c)(iii) and (iv) shall be specified for each resulting Borrowing);

(ii)                                  the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii)                               whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

(iv)                              if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one (1) month’s duration.

38

(d)                                 Notice to Lenders by the Administrative Agent.  Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e)                                  Effect of Failure to Deliver Timely Interest Election Request and Events of Default on Interest Election.  If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing.  Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing:  (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing (and any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective) and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

Section 2.06                            Funding of Borrowings.

(a)                                  Funding by Lenders.  Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 2:00 p.m., Eastern time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders; provided that Swingline Loans shall be made as provided in Section 2.04.  The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to the account of the Borrower designated in the Borrowing Request; provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.09(e) shall be remitted by the Administrative Agent to the relevant Issuing Bank.  Nothing herein shall be deemed to obligate any Lender to obtain the funds for its Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for its Loan in any particular place or manner.

(b)                                 Presumption of Funding by the Lenders.  Unless the Administrative Agent shall have received notice from a Lender prior to the proposed time of any Borrowing (or prior to the proposed time of any same day ABR Borrowing) that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.06(a) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount.  In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender agrees to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.  If such Lender does not pay such corresponding amount to the Administrative Agent within three (3) Business Days after demand, the Borrower agrees to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent at the interest rate

39

applicable to ABR Loans.  If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

Section 2.07                            Termination, Reduction and Increase of Commitments.

(a)                                  Optional Termination and Reduction of Commitments.

(i)                                     The Borrower may at any time terminate, or from time to time reduce, the total Commitments; provided that (A) each reduction of the total Commitments shall be in an amount that is an integral multiple of $1,000,000 and not less than $10,000,000 and (B) the Borrower shall not terminate or reduce the total Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 3.04(c), the total Credit Exposures would exceed the total Commitments.

(ii)                                  The Borrower shall notify the Administrative Agent of any election to terminate or reduce the total Commitments under Section 2.07(a)(i) at least three (3) Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof.  Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof.  Each notice delivered by the Borrower pursuant to this Section 2.07(a)(ii) shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned upon (i) the effectiveness of other credit facilities or (ii) the issuance or incurrence of other indebtedness permitted under Section 9.02, and in each such case, such notice may be revoked by the Borrower by notice to the Administrative Agent on or prior to the specified effective date if such condition is not satisfied.

(iii)                               Other than as provided in Section 2.07(a)(iv) below, any termination or reduction of the Commitments shall be permanent and may not be reinstated except pursuant to Section 2.07(b).  Each reduction of the Commitments shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage.

(iv)                              If any Lender shall be a Defaulting Lender, the Borrower, at the Borrower’s election may elect to terminate such Defaulting Lender’s Commitment hereunder; provided that (i) such termination must be of the Defaulting Lender’s entire Commitment, (ii) the Borrower shall pay all amounts owed by the Borrower to such Defaulting Lender under this Agreement and under the other Loan Documents (including principal of and interest on the Loans owed to such Defaulting Lender, commitment fees accrued prior to the time such Defaulting Lender became a Defaulting Lender, and letter of credit fees accrued prior to the time such Defaulting Lender became a Defaulting Lender but specifically excluding any amounts owing under Section 5.02 as result of such payment of Loans) and shall deposit with the Administrative Agent cash collateral in the amount equal to such Defaulting Lender’s ratable share of the LC Exposure, including

40

any such LC Exposure that has been reallocated pursuant to Section 4.05(a)(iv); and (iii) a Defaulting Lender’s Commitment may be terminated by the Borrower under this Section 2.07(a)(iv) if and only if at such time, the Borrower has elected, or is then electing, to terminate the Commitments of all then existing Defaulting Lenders.  Upon written notice to the Defaulting Lender and Administrative Agent of the Borrower’s election to terminate a Defaulting Lender’s Commitment pursuant to this clause (c) and the payment and deposit of amounts required to be made by the Borrower under clause (ii) above, (A) such Defaulting Lender shall cease to be a “Lender” hereunder for all purposes except that such Lender’s rights under Section 5.01, Section 5.03, Section 12.02, and Section 12.03 shall continue with respect to events and occurrences occurring before or concurrently with its ceasing to be a “Lender” hereunder, (B) such Defaulting Lender’s Commitment shall be terminated, and (C) such Defaulting Lender shall be relieved of its obligations hereunder, provided that, any such termination will not be deemed to be a waiver or release of any claim by Borrower, the Administrative Agent or any Lender may have against such Defaulting Lender.

(b)                                 Optional Increase in Commitments.

(i)                                     Subject to the conditions set forth in Section 2.07(b)(ii), the Borrower may increase the total Commitments then in effect 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”).

(ii)                                  Any increase in the Commitments shall be subject to the following additional conditions:

(A)                              at no time shall the total Commitments exceed the Maximum Credit Amount;

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

(C)                                the Borrower shall have paid all compensation required by Section 5.02 (if any);

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

(E)                                 if the Borrower elects to increase the total Commitments by increasing the Commitment of a Lender, the Borrower and such Lender shall execute and deliver to the Administrative Agent a certificate substantially in the form of Exhibit G-1 (a “Commitment Increase Certificate”), and if requested by such Lender, the Borrower shall deliver a new Note payable to the order of such Lender in a principal amount equal to its Commitment after giving effect to such increase, and otherwise duly completed;

(F)                                 if the Borrower elects to increase the total Commitments by causing an Additional Lender to become a party to this Agreement, then, upon the

41

prior written consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed), the Borrower and such Additional Lender shall execute and deliver to the Administrative Agent a certificate substantially in the form of Exhibit G-2 (an “Additional Lender Certificate”), together with an Administrative Questionnaire, and if requested by such Additional Lender, the Borrower shall deliver a Note payable to the order of such Additional Lender in a principal amount equal to its Commitment, and otherwise duly completed; and

(G)                                the Borrower and its Restricted Subsidiaries shall have delivered to the Administrative Agent such legal opinions, resolutions, amendment to Security Instruments and other documents as the Administrative Agent may reasonably request.

(iii)                               Subject to acceptance and recording thereof pursuant to Section 2.07(b)(iv), from and after the effective date specified in the Commitment Increase Certificate or the Additional Lender Certificate:  (A) the amount of the total Commitments shall be increased as set forth therein, and (B) in the case of an Additional Lender Certificate, any Additional Lender party thereto shall be a party to this Agreement and the other Loan Documents and have the rights and obligations of a Lender under this Agreement and the other Loan Documents.  In addition, the Lender or the Additional Lender, as applicable, shall purchase a pro rata portion of the outstanding Loans (and participation interests in Letters of Credit) of each of the other Lenders (and such Lenders hereby agree to sell and to take all such further action to effectuate such sale) such that each Lender (including any Additional Lender, if applicable) shall hold its Applicable Percentage of the outstanding Loans (and participation interests) after giving effect to the increase in the total Commitments.

(iv)                              Upon its receipt of a duly completed Commitment Increase Certificate or an Additional Lender Certificate, executed by the Borrower and the Lender or the Borrower and the Additional Lender party thereto, as applicable, the Administrative Questionnaire referred to in Section 2.07(b)(ii), if applicable, the written consent of the Administrative Agent to such increase required by Section 2.07(b)(i)(F), and all other documents and payments required by this Section 2.07(b), the Administrative Agent shall accept such Commitment Increase Certificate or Additional Lender Certificate and record the information contained therein in the Register required to be maintained by the Administrative Agent pursuant to Section 12.04(b)(iv).

Section 2.08                            Borrowing Base.

(a)                                  Upstream Component.

(i)                                     Initial Upstream Component.  For the period from and including the Effective Date to but excluding the first Redetermination Date, the amount of the Upstream Component shall be $353,000,000; provided, that if the Borrower issues any unsecured Indebtedness in excess of $350,000,000 prior to the Effective Date, such $353,000,000 shall be reduced in accordance with Section 2.08(a)(vi).  Notwithstanding the foregoing, the Upstream Component may be subject to further adjustments from time

42

to time before the first Redetermination Date pursuant to Section 2.08(a)(v), Section 2.08(a)(vii) or  Section 2.08(a)(viii).

(ii)                                  Upstream Component Redeterminations.  The Upstream Component shall be redetermined semi-annually in accordance with this Section 2.08(a)(ii) (a “Scheduled Upstream Component Redetermination”), and subject to Section 2.08(a)(iv), such redetermined Upstream Component (and resulting new Borrowing Base) shall become effective and applicable to the Borrower, the Agents, any Issuing Bank and the Lenders on April 1st and October 1st of each year, commencing October 1, 2011.  In addition, the Borrower may, by notifying the Administrative Agent thereof, and the Administrative Agent may, at the direction of the Majority Lenders, by notifying the Borrower thereof, elect to cause the Upstream Component to be redetermined one time each between Scheduled Upstream Component Redeterminations in accordance with this Section 2.08(a)(ii) (each such redetermination, an “Interim Upstream Component Redetermination”).

(iii)                               Upstream Component Redetermination Procedure.

(A)                              Each Upstream Component Redetermination shall be effectuated as follows:  Upon receipt by the Administrative Agent of (A) the Reserve Report and the certificate required to be delivered by the Borrower to the Administrative Agent, in the case of a Scheduled Upstream Component Redetermination, pursuant to Section 8.12(a) and (c), and, in the case of an Interim Upstream Component Redetermination, pursuant to Section 8.12(b) and (c), and (B) such other reports, data and supplemental information, including, without limitation, the information provided pursuant to Section 8.12(c), as may, from time to time, be reasonably requested by the Majority Lenders (the Reserve Report, such certificate and such other reports, data and supplemental information being the “Engineering Reports”), the Administrative Agent shall evaluate the information contained in the Engineering Reports and shall, in good faith, propose a new Upstream Component (the “Proposed Upstream Component”) based upon such Engineering Report and such other information (consistent with the Administrative Agent’s normal oil and gas lending criteria and the price assumptions used by the Administrative Agent in evaluating oil and gas loans generally, in each case as they exist at the particular time).

(B)                                The Administrative Agent shall notify the Borrower and the Lenders of the Proposed Upstream Component (the “Proposed Upstream Component Notice”):

(1)                                  in the case of a Scheduled Upstream Component Redetermination (1) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on or before the March 15th and September 15th of such year following the date of delivery, or (2) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to

43

Section 8.12(a) and (c) in a timely and complete manner, then promptly after the Administrative Agent has received complete Engineering Reports from the Borrower and has had a reasonable opportunity to determine the Proposed Upstream Component in accordance with Section 2.08(a)(iii)(A); and

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

(C)                                Any Proposed Upstream Component that would increase the Upstream Component then in effect must be approved or deemed to have been approved by all of the Lenders (except for any Defaulting Lender) as provided in this Section 2.08(a)(iii)(C); and any Proposed Upstream Component that would decrease or maintain the Upstream Component then in effect must be approved or be deemed to have been approved by the Required Lenders as provided in this Section 2.08(a)(iii)(C).  Upon receipt of the Proposed Upstream Component Notice, each Lender shall have fifteen (15) days to, in its sole discretion and consistent with such Lender’s normal and customary oil and gas lending criteria, agree with the Proposed Upstream Component or disagree with the Proposed Upstream Component by proposing an alternate Upstream Component.  If at the end of such fifteen (15) days, any Lender has not communicated its approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be an approval of the Proposed Upstream Component.  If, at the end of such 15-day period, all of the Lenders, in the case of a Proposed Upstream Component that would increase the Upstream Component then in effect, or the Required Lenders, in the case of a Proposed Upstream Component that would decrease or maintain the Upstream Component then in effect, have approved or deemed to have approved, as aforesaid, then the Proposed Upstream Component shall become the new Upstream Component and the Borrowing Base, giving effect to the new Upstream Component, shall become the new Borrowing Base, effective on the date specified in Section 2.08(a)(iv).  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 (1) the Administrative Agent shall poll the Lenders to ascertain the highest Upstream Component then acceptable to all Lenders or the number of Lenders sufficient to constitute the Required Lenders, as applicable, and such amount shall become the new Upstream Component and the Borrowing Base, giving effect to the new Upstream Component, shall become the new Borrowing Base, effective on the date specified in Section 2.08(a)(iv) and (2) Borrower may replace any Non-Consenting Lender with respect to such Proposed Upstream Component as provided in Section 5.04(b).

(iv)                              Effectiveness of a Redetermined Upstream Component.  After a Proposed Upstream Component is approved or is deemed to have been approved by all of the Lenders or the Required Lenders, as applicable, pursuant to Section 2.08(a)(iii)(C), the Administrative Agent shall notify the Borrower and the Lenders of the amount of the

44

redetermined Upstream Component (the “New Upstream Component Notice”) and the resulting new Borrowing Base, and such amounts shall become the new Upstream Component and the new Borrowing Base, respectively, effective and applicable to the Borrower, the Agents, any Issuing Bank and the Lenders:

(A)                              in the case of a Scheduled Upstream Component Redetermination, (A) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on the April 1st or October 1st, as applicable, following such notice, or (B) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on the Business Day next succeeding delivery of such notice; and

(B)                                in the case of an Interim Upstream Component Redetermination or an adjustment to the Upstream Component under Section 2.08(a)(v), Section 2.08(a)(vi), Section 2.08(a)(vii), or Section 2.08(a)(viii), on the Business Day next succeeding delivery of such notice.

Such amount shall then become the Upstream Component until the next Scheduled Upstream Component Redetermination Date, the next Interim Upstream Component Redetermination Date or the next adjustment to the Upstream Component under Section 2.08(a)(v), Section 2.08(a)(vi), Section 2.08(a)(vii), or Section 2.08(a)(viii), whichever occurs first.  Notwithstanding the foregoing, no Upstream Component Redetermination shall become effective until the New Upstream Component Notice related thereto is received by the Borrower.

(v)                                 Reduction of Upstream Component Upon Asset Dispositions.  Upon the Disposition of any Upstream Component Properties, if the sum of (A) the attributed Upstream Component value of all Upstream Component Properties Disposed of since the last redetermination of the Upstream Component and (B) the aggregate Midstream Attributed Value of Midstream Properties Disposed of since the last calculation of the Midstream Component exceeds five percent (5%) of the Borrowing Base then in effect, the Administrative Agent shall adjust the Upstream Component in an amount equal to the Upstream Component value attributable to the Upstream Component Properties being Disposed of.  The Administrative Agent shall promptly notify the Borrower and the Lenders in writing of the Upstream Component value attributable to the Upstream Component Properties being Disposed of in the calculation of the then-effective Upstream Component and upon receipt of such notice, the Upstream Component shall be reduced by such amount.

(vi)                              Reduction of Upstream Component Upon Issuance of Unsecured Indebtedness.  Upon the issuance or incurrence of any unsecured indebtedness after the date hereof pursuant to Section 9.02(h), the Upstream Component then in effect shall be reduced by an amount equal to the product of (i) 0.25 multiplied by the principal amount of such newly issued indebtedness (without regard to any original issue discount) and (ii)

45

the Upstream Weighting.  The Administrative Agent shall promptly notify the Borrower and the Lenders of the new Upstream Component.

(vii)                           Reduction of Upstream Component Associated with Title Defects or Exceptions.  The Upstream Component may be reduced from time to time as provided in Section 8.13(c).

(viii)                        Reduction of Upstream Component Upon Termination of Hedge Positions.  If the Borrower or a Restricted Subsidiary shall terminate prior to the contracted term therefore or create any off-setting positions in respect of any Upstream Hedges (whether evidenced by a floor, put or Hedging Agreement) (a “Hedge Unwind”) and the aggregate net value of all such Hedge Unwinds since the last determination of the Upstream Component exceeds 2.5% of the effective Upstream Component, then the Administrative Agent shall have the right to adjust the Upstream Component in an amount equal to the Upstream Component value attributable to such terminated or off-setting hedge positions in the calculation of the then-effective Upstream Component.  The Administrative Agent shall promptly notify the Borrower and the Lenders in writing of any such adjustment to the Upstream Component and the resulting new Upstream Component and resulting new Borrowing Base giving effect to such new Upstream Component, shall become effective as of the date of such notice.

(b)                                 Midstream Component.

(i)                                     Initial Midstream Component.  For the period from and including the Effective Date to but excluding the first Scheduled Midstream Component Recalculation, the amount of the Midstream Component shall be $322,000,000

(ii)                                  Scheduled Recalculations of the Midstream Component.  Midstream EBITDA (and hence the Midstream Component of the Borrowing Base) will be recalculated quarterly (each such recalculation, a “Scheduled Midstream Component Recalculation”) in connection with the delivery of the consolidated financial statements of the Borrower and its Consolidated Restricted Subsidiaries pursuant to Section 8.01(a), Section 8.01(b) and the compliance certificate pursuant to Section 8.01(c).  The Administrative Agent shall notify the Borrower and the Lenders of the amount of the recalculated Midstream Component (the “New Midstream Component Notice”) and the resulting new Borrowing Base, and such amount shall become the new Midstream Component and the Borrowing Base, giving effect to the new Midstream Component, shall become the new Borrowing Base, effective and applicable to the Borrower, the Agents, any Issuing Bank and the Lenders as of the day such financial statements are delivered.

(iii)                               Pro Forma Adjustments to Midstream Component.  Pro forma adjustments, as reasonably determined by the Borrower and approved by the Administrative Agent, shall be made to Midstream EBITDA (and hence the Midstream Component of the Borrowing Base) between Scheduled Midstream Component Recalculations for (A) acquisitions of Midstream Properties (either through a direct acquisition of such Midstream Properties or through a Permitted Acquisition),

46

individually or in the aggregate, with Midstream Attributed Value in excess of 5% of then effective Midstream Component since the last recalculation pursuant to Section 2.08(b)(ii), (B) Dispositions of Midstream Properties if the sum of (1) the attributed Upstream Component value of all Upstream Component Properties Disposed of since the last redetermination of the Upstream Component and (2) the aggregate Midstream Attributed Value of Midstream Properties sold since the last recalculation of the Midstream Component exceeds five percent (5%) of the Borrowing Base then in effect and (C) Material Projects as provided in Section 9.01(e).  The Administrative Agent shall notify the Borrower and the Lenders of the amount of the adjusted Midstream Component  and the resulting new Borrowing Base, and such amount shall become the new Midstream Component and the Borrowing Base, giving effect to the adjusted Midstream Component, shall become the new Borrowing Base, shall be effective and applicable to the Borrower, the Agents, any Issuing Bank and the Lenders as of the day of such notice.

Section 2.09                            Letters of Credit.

(a)                                  General.  The Borrower, the Administrative Agent, the Issuing Bank, and Lenders hereby agree that all Existing Letters of Credit shall be deemed to be issued under this Agreement as of the Effective Date and shall constitute Letters of Credit hereunder for all purposes (except that no Issuing Bank’s standard issuance fee shall be payable on such deemed issuance).  Subject to the terms and conditions set forth herein, the Borrower may request the issuance of dollar denominated Letters of Credit for its own account or for the account of any of its Restricted Subsidiaries, in a form reasonably acceptable to the Administrative Agent and the applicable Issuing Bank, at any time and from time to time during the Availability Period.  In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any Letter of Credit Agreement, the terms and conditions of this Agreement shall control.

(b)                                 Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions.  To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or facsimile (or transmit by electronic communication, if arrangements for doing so have been approved by the applicable Issuing Bank) to the applicable Issuing Bank and the Administrative Agent (not less than three (3) Business Days in advance of the requested date of issuance, amendment, renewal or extension) a notice:

(i)                                     requesting the issuance of a Letter of Credit or identifying the Letter of Credit to be amended, renewed or extended;

(ii)                                  specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day);

(iii)                               specifying the date on which such Letter of Credit is to expire (which shall comply with Section 2.09(c));

(iv)                              specifying the amount of such Letter of Credit;

47

(v)                                 specifying the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit; and

(vi)                              specifying the current total Credit Exposures (without regard to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit) and the pro forma total Credit Exposures (giving effect to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit).

Each notice shall constitute a representation that after giving effect to the requested issuance, amendment, renewal or extension, as applicable, (A) the LC Exposure shall not exceed the LC Commitment and (B) the total Credit Exposures shall not exceed the total Commitments.

If requested by an Issuing Bank, the Borrower also shall submit a letter of credit application on such Issuing Bank’s standard form in connection with any request for a Letter of Credit.

(c)                                  Expiration Date.  Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one (1) year after the date of the issuance of such Letter of Credit, provided that such Letter of Credit may provide for automatic extensions of such expiration date (such Letter of Credit, an “Auto-Extension Letter of Credit”) for additional periods of 365 days thereafter, and (ii) the date that is five (5) Business Days prior to the Maturity Date.  The Borrower shall be required to make a specific request to the applicable Issuing Bank for any extension of an Auto-Extension Letter of Credit.  Once an Auto-Extension Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) the applicable Issuing Bank to permit the extension of such Letter of Credit at any time to an expiry date not later than five (5) Business Days prior to the Maturity Date; provided, however, that such Issuing Bank shall not permit any such extension if (A) such Issuing Bank has determined that it would not be permitted at such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof, or (B) it has received notice (which may be by telephone or in writing) from the Administrative Agent, on or before the day that is five (5) Business Days before the last day in which notice of non-extension for such Letter of Credit may be given, that one or more of the applicable conditions specified in Section 6.02 is not then satisfied, and directing such Issuing Bank not to permit such extension.

(d)                                 Participations.  By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of any Issuing Bank or the Lenders, the applicable Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit.  In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the applicable Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by such Issuing Bank and not reimbursed by the Borrower on the date due as provided in Section 2.09(e), or of any reimbursement payment required to be refunded to the Borrower for any reason.  Each Lender acknowledges and agrees that its obligation to acquire participations

pursuant to this Section 2.09(d) in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default, the existence of a Borrowing Base Deficiency or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e)                                  Reimbursement.  If any Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, Eastern time, on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., Eastern time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 12:00 noon, Eastern time, on (i) the Business Day that the Borrower receives such notice, if such notice is received prior to 10:00 a.m., Eastern time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that the Borrower shall, subject to the conditions to Borrowing set forth herein, be deemed to have requested, and the Borrower does hereby request under such circumstances, that such payment be financed with an ABR Borrowing (or, if such LC Disbursement is less than $1,000,000, a Swingline Loan) in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Borrowing (or Swingline Loan).  If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof.  Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.05(a) with respect to Loans made by such Lender (and Section 2.05(a) shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to such Issuing Bank the amounts so received by it from the Lenders.  Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this Section 2.09(e), the Administrative Agent shall distribute such payment to such Issuing Bank or, to the extent that Lenders have made payments pursuant to this Section 2.09(e) to reimburse such Issuing Bank, then to such Lenders and such Issuing Bank as their interests may appear.  Any payment made by a Lender pursuant to this Section 2.09(e) to reimburse such Issuing Bank for any LC Disbursement (other than the funding of ABR Loans or a Swingline Loan as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

(f)                                    Obligations Absolute.  The Borrower’s obligation to reimburse LC Disbursements as provided in Section 2.09(e) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit, any Letter of Credit Agreement or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by any Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not substantially comply with the terms of such Letter of Credit or

49

any Letter of Credit Agreement, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.09(f), constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder, absent such Issuing Bank’s gross negligence or willful misconduct.  Neither the Administrative Agent, the Lenders nor any Issuing Bank, nor any of their Related Parties shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of any Issuing Bank; provided that the foregoing shall not be construed to excuse such Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by such Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof.  The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of any Issuing Bank (as finally determined by a court of competent jurisdiction), such Issuing Bank shall be deemed to have exercised all requisite care in each such determination.  In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, such Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g)                                 Disbursement Procedures.  The applicable Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit.  Such Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by facsimile) of such demand for payment and whether such Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse such Issuing Bank and the Lenders with respect to any such LC Disbursement.

(h)                                 Interim Interest.  If any Issuing Bank shall make any LC Disbursement, then, until the Borrower shall have reimbursed such Issuing Bank for such LC Disbursement (either with its own funds or a Borrowing under Section 2.09(e)), the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans.  Interest accrued pursuant to this Section 2.09(h) shall be for the account of the applicable Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.09(e) to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment.

50

(i)                                     Replacement of an Issuing Bank.  Any Issuing Bank may be replaced at any time by written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank.  The Administrative Agent shall notify the Lenders of any such replacement of the replaced Issuing Bank.  At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 3.05(b).  From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit to be issued by it thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor and any other existing Issuing Banks or to any previous Issuing Bank, or to such successor and all other existing Issuing Banks and previous Issuing Banks, as the context shall require.  After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

(j)                                     Cash Collateralization.  If (i) any Event of Default shall occur and be continuing and the Borrower receives notice from the Administrative Agent or the Majority Lenders demanding the deposit of cash collateral pursuant to this Section 2.09(j), or (ii) the Borrower is required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then the Borrower shall deposit, in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to, in the case of an Event of Default, the LC Exposure, and in the case of a payment required by Section 3.04(c), the amount of such excess as provided in Section 3.04(c), as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower or any Restricted Subsidiary described in Section 10.01(i) or Section 10.01(j).  The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Banks and the Lenders, an exclusive first priority and continuing perfected security interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire transfers made thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor.  The Borrower’s obligation to deposit amounts pursuant to this Section 2.09(j) shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower or any of its Subsidiaries may now or hereafter have against any such beneficiary, any Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever.  Such deposit shall be held as collateral securing the payment and performance of the Borrower’s and the Guarantor’s obligations under this Agreement and the other Loan Documents.  The Administrative Agent shall have exclusive dominion and control, including the

51

exclusive right of withdrawal, over such account.  Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest.  Interest or profits, if any, on such investments shall accumulate in such account.  Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Banks for LC Disbursements for which they have not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time, and if such moneys shall exceed the LC Exposure at any time, such excess shall be reimbursed to the Borrower.  If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three (3) Business Days after all Events of Default have been cured or waived.

ARTICLE III
PAYMENTS OF PRINCIPAL AND INTEREST; PREPAYMENTS; FEES

Section 3.01                            Repayment of Loans.  The Borrower hereby unconditionally promises to pay (a) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan (other than the Swingline Loans) on the Termination Date and (b) to the Swingline Lender or the Administrative Agent for the account of each Lender, as applicable, the outstanding aggregate principal and accrued and unpaid interest under each Swingline Loan no later than the earlier to occur of (i) the tenth (10th) day following such Swingline Loan Borrowing and (ii) the Termination Date; provided, that on each date that a Borrowing (other than a Swingline Loan) is made, the Borrower shall repay all Swingline Loans then outstanding.

Section 3.02                            Interest.

(a)                                  ABR Loans.  The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

(b)                                 Eurodollar Loans.  The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

(c)                                  Swingline Loans.  Each Swingline Loan shall bear interest at the LIBOR Reference Rate plus the Applicable Margin for a Eurodollar Borrowing, but in no event to exceed the Highest Lawful Rate.

(d)                                 Post-Default Rate.  Notwithstanding the foregoing, if an Event of Default has occurred and is continuing, then, upon request of Majority Lenders, all Loans outstanding and any fees or amounts payable by the Borrower or any Restricted Subsidiary hereunder or under any other Loan Document,  shall bear interest from the date of such Event of Default at the rate then applicable to such Loans or such fees or amounts, plus the Applicable Margin, if any, plus an additional two percent (2%), but in no event to exceed the Highest Lawful Rate.

52

(e)                                  Interest Payment Dates.  Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and on the Termination Date; provided that (i) interest accrued pursuant to Section 3.02(d) shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than an optional prepayment of an ABR Loan prior to the Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(f)                                    Interest Rate Computations.  All interest hereunder shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), except that interest computed by reference to the Alternate Base Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day).  The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error, and be binding upon the parties hereto.

Section 3.03                            Alternate Rate of Interest.  If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(a)                                  the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate for such Interest Period; or

(b)                                 the Administrative Agent is advised by the Majority Lenders that the Adjusted LIBO Rate or LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or facsimile as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing.

Section 3.04                            Prepayments.

(a)                                  Optional Prepayments.  The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with Section 3.04(b).

(b)                                 Notice and Terms of Optional Prepayment.  The Borrower shall notify the Administrative Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender) by telephone (confirmed by facsimile or other electronic transmission) of any

53

prepayment hereunder not later than 12:00 noon, Eastern time, on the date of prepayment.  Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.07(a), then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.07(a).  Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof.  Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02.  Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing.  Prepayments shall be accompanied by accrued interest to the extent required by Section 3.02.

(c)                                  Mandatory Prepayments.

(i)                                     If, after giving effect to any termination or reduction of the total Commitments pursuant to Section 2.07(a), the total Credit Exposures exceeds the total Commitments, then the Borrower shall make a prepayment in accordance with Section 3.04(c)(v) on the date of such termination or reduction in an aggregate principal amount equal to such excess.

(ii)                                  If a Borrowing Base Deficiency results from or exists immediately after any adjustment of the Borrowing Base due to a Scheduled Upstream Component Redetermination or Interim Upstream Component Redetermination of the Upstream Component or Scheduled Midstream Component Recalculation of the Midstream Component, then within thirty (30)  days of the effective date of such new Borrowing Base, the Borrower shall elect (A) to prepay the Loans in an aggregate principal amount equal to such Deficiency Amount or (B) to pay such Deficiency Amount in six (6) equal installments, the first such installment being due and payable by the first Business Day after such election has been made and the remaining installments due monthly thereafter until such Deficiency Amount is paid in full; provided, that all payments under this Section 3.04(c)(ii) must be made prior to the Maturity Date.

(iii)                               If a Borrowing Base Deficiency results from or exists immediately after any adjustment to the Borrowing Base other than pursuant to any Scheduled Upstream Component Redetermination or Interim Upstream Component Redetermination of the Upstream Component or Scheduled Midstream Component Recalculation of the Midstream Component, then the Borrower shall make a prepayment on the date of such adjustment in an aggregate amount equal to such Deficiency Amount.

(iv)                              Each payment made pursuant to this Section 3.04(c) shall be used to prepay the Borrowings, and if any Borrowing Base Deficiency remains after prepaying all of the Borrowings as a result of an LC Exposure, such excess shall be paid to the Administrative Agent on behalf of the Lenders to be held as cash collateral as provided in Section 2.09(j).  Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied, first, to any Swingline Loans then outstanding, second, ratably to any ABR Borrowings then outstanding, and, third, to any Eurodollar Borrowings then outstanding,

54

and if more than one Eurodollar Borrowing is then outstanding, to each such Eurodollar Borrowing in order of priority beginning with the Eurodollar Borrowing with the least number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar Borrowing with the most number of days remaining in the Interest Period applicable thereto.

(v)                                 Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied ratably to the Loans included in the prepaid Borrowings.  Prepayments pursuant to this Section 3.04(c) shall be accompanied by accrued interest to the extent required by Section 3.02.

(d)                                 No Premium or Penalty.  Prepayments permitted or required under this Section 3.04 shall be without premium or penalty, except as required under Section 5.02.

Section 3.05                            Fees.

(a)                                  Commitment Fees.  The Borrower agrees to pay to the Administrative Agent for the account of each Lender (other than a Defaulting Lender) a commitment fee, which shall accrue at the applicable Commitment Fee Rate on the average daily amount of the unused amount of the Commitment of such Lender (notwithstanding such Lender’s Applicable Percentage of the Borrowing Base) during the period from and including the date of this Agreement to but excluding the Termination Date; provided that for purposes of calculating commitment fees pursuant to this Section 3.05(a), Swingline Loans shall not be deemed to be a utilization of Commitments.  Accrued commitment fees shall be payable in arrears on the last day of March, June, September and December of each year and on the Termination Date, commencing on the first such date to occur after the date hereof.  All commitment fees shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b)                                 Letter of Credit Fees.  The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender (other than a Defaulting Lender except as provided in Section 4.05(a)(iii)(B)) a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Margin used to determine the interest rate applicable to Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, (ii) to the applicable Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, and (iii) to the applicable Issuing Bank, for its own account, its standard fees with respect to the amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder.  Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each

55

year shall be payable on the third (3rd) Business Day following such last day, commencing on the first such date to occur after the date of this Agreement; provided that all such fees shall be payable on the Termination Date and any such fees accruing after the Termination Date shall be payable on demand.  Any other fees payable to any Issuing Bank pursuant to this Section 3.05(b) shall be payable within ten (10) days after demand.  All participation fees and fronting fees shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(c)                                  Administrative Agent Fees.  The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent.

ARTICLE IV
PAYMENTS; PRO RATA TREATMENT; SHARING OF SET-OFFS.

Section 4.01                            Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a)                                  Payments by the Borrower.  The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 12:00 noon, Eastern time, on the date when due, in immediately available funds, without defense, deduction, recoupment, set-off or counterclaim.  Fees, once paid, shall be fully earned and shall not be refundable under any circumstances.  Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon.  All such payments shall be made to the Administrative Agent at its offices specified in Section 12.01, except payments to be made directly to any Issuing Bank as expressly provided herein and except that payments pursuant to Section 5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the Persons entitled thereto.  The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof.  If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension.  All payments hereunder shall be made in dollars.

(b)                                 Application of Insufficient Payments.  If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties.

56

(c)                                  Sharing of Payments by Lenders.  If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements or Swingline Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements or Swingline Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements and Swingline Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this Section 4.01(c) shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements and Swingline Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall apply).  The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

Section 4.02                            Presumption of Payment by the Borrower.  Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or any Issuing Bank that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the applicable Issuing Bank, as the case may be, the amount due.  In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the applicable Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or such Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

Section 4.03                            Certain Deductions by the Administrative Agent.  If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.06(b), Section 2.09(d), Section 2.09(e) or Section 4.02 then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

Section 4.04                            Disposition of Proceeds.  The Security Instruments contain an assignment by the Borrower and/or the Guarantors unto and in favor of the Administrative Agent for the

57

benefit of the Lenders of all of the Borrower’s or each Guarantor’s interest in and to production and all proceeds attributable thereto which may be produced from or allocated to the Upstream Component Properties.  The Security Instruments further provide in general for the application of such proceeds to the satisfaction of the Secured Obligations and other obligations described therein and secured thereby.  Notwithstanding the assignment contained in such Security Instruments, until the occurrence of an Event of Default, (a) the Administrative Agent and the Lenders agree that they will neither notify the purchaser or purchasers of such production nor take any other action to cause such proceeds to be remitted to the Administrative Agent or the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower and its Restricted Subsidiaries and (b) the Lenders hereby authorize the Administrative Agent to take such actions as may be necessary to cause such proceeds to be paid to the Borrower and/or such Restricted Subsidiaries.

Section 4.05                            Defaulting Lenders.

(a)                                  Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

(i)                                     Waivers and Amendments.  Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definitions of Majority Lenders and Required Lenders.

(ii)                                  Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article X or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 12.08 shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to any Issuing Bank or Swingline Lender hereunder; third, to cash collateralize the Fronting Exposure of any Issuing Bank and Swingline Lender with respect to such Defaulting Lender; fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement and (y) cash collateralize the Issuing Banks’ future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued and Swingline Loans made under this Agreement; sixth, to the payment of any amounts owing to the Lenders, the Issuing Banks or Swingline Lenders as a result of any judgment of a court of competent jurisdiction obtained by any Lender, the Issuing Banks or Swingline Lenders against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment

58

of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or LC Disbursements in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 6.02 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and LC Disbursements owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or LC Disbursements owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in Letters of Credit and Swingline Loans are held by the Lenders pro rata in accordance with the Commitments under the applicable Facility without giving effect to Section 4.05(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 4.05(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii)                               Certain Fees.

(A)                              No Defaulting Lender shall be entitled to receive any Commitment Fee for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender)

(B)                                Each Defaulting Lender shall be entitled to receive fees with respect to its participations in Letters of Credit for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Applicable Percentage of the stated amount of Letters of Credit for which such Defaulting Lender has provided cash collateral pursuant to Section 2.09(j).

(C)                                With respect to any fee not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the Borrower shall (x) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in any outstanding Letters of Credit or Swingline Loans that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to each Issuing Bank and Swingline Lender, as applicable, the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to such Issuing Bank’s or Swingline Lender’s Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such fee.

(iv)                              Reallocation of Participations to Reduce Fronting Exposure.  All or any part of such Defaulting Lender’s participation in any outstanding Letters of Credit and Swingline Loans shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Applicable Percentages (calculated without regard to

59

such Defaulting Lender’s Commitment) but only to the extent that (x) the conditions set forth in Section 6.02 are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the Credit Exposure of any Non-Defaulting Lender to exceed such Non-Defaulting Lender’s Loan Limit.  No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation.

(v)                                 Cash Collateral, Repayment of Swingline Loans.  If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under law, (x) first, prepay Swingline Loans in an amount equal to the Swingline Lenders’ Fronting Exposure and (y) second, cash collateralize the Issuing Banks’ Fronting Exposure in accordance with the procedures set forth in Section 2.09(j).

(b)                                 Defaulting Lender Cure.  If the Borrower, the Administrative Agent and each Swingline Lender and Issuing Bank agree in writing that a Lender is no longer 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 (which may include arrangements with respect to any cash collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit and Swingline Loans to be held pro rata by the Lenders in accordance with the Commitments under the applicable Facility (without giving effect to Section 4.05(a)(iv), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, 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 that Lender’s having been a Defaulting Lender.

(c)                                  New Swingline Loans/Letters of Credit.  So long as any Lender is a Defaulting Lender, (i) the Swingline Lender shall not be required to fund any Swingline Loans unless it is satisfied that it will have no Fronting Exposure after giving effect to such Swingline Loan and (ii) no Issuing Bank shall be required to issue, extend, renew or increase any Letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto.

ARTICLE V
INCREASED COSTS; BREAK FUNDING PAYMENTS; TAXES; ILLEGALITY

Section 5.01                            Increased Costs.

(a)                                  Eurodollar Changes in Law.  If any Change in Law shall:

60

(i)                                     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 (except  any such reserve requirement reflected in the Adjusted LIBO Rate);

(ii)                                  impose on any Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender; OR

(iii)                               subject any Lender to any Taxes with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit or any Eurodollar Rate Loan made by it (other than (A) Indemnified Taxes covered by Section 5.03 and (B) Excluded Taxes);

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered; provided that the Borrower shall have no obligation to pay any such costs incurred or suffered more than six (6) months prior to the demand therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six-month period referred to above shall be extended to include the period of retroactive effect thereof.

(b)                                 Capital Requirements.  If any Lender or any Issuing Bank determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or such Issuing Bank’s capital or on the capital of such Lender’s or such Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by such Issuing Bank, to a level below that which such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuing Bank’s policies and the policies of such Lender’s or such Issuing Bank’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or such Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company for any such reduction suffered; provided that the Borrower shall have no obligation to pay any such costs incurred or suffered more than six (6) months prior to the demand therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six-month period referred to above shall be extended to include the period of retroactive effect thereof.

(c)                                  Certificates.  A certificate of a Lender or an Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or such Issuing Bank or its holding company, as the case may be, as specified in Section 5.01(a) or (b) shall be delivered to the Borrower and shall be conclusive absent manifest error.  The Borrower shall pay such Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate within ten (10) days after receipt thereof.

61

(d)                                 Effect of Failure or Delay in Requesting Compensation.  Except as provided above, failure or delay on the part of any Lender or any Issuing Bank to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation.

Section 5.02                            Break Funding Payments.  In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan into an ABR Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 5.04(b), then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event.  In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market.

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 5.02 shall be delivered to the Borrower and shall be conclusive absent manifest error.  The Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

Section 5.03                            Taxes.

(a)                                  Payments Free of Taxes.  Any and all payments by or on account of any obligation of the Borrower or any Guarantor under any Loan Document shall be made free and clear of and without deduction or withholding for any Indemnified Taxes or Other Taxes; provided that if the Borrower or any Guarantor shall be required by applicable law to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 5.03(a)), the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower or such Guarantor shall make such deductions and (iii) the Borrower or such Guarantor shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b)                                 Payment of Other Taxes by the Borrower.  The Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

62

(c)                                  Indemnification by the Borrower.  The Borrower shall indemnify the Administrative Agent, each Lender and each Issuing Bank, within ten (10) days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or such Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 5.03) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority.  A certificate of the Administrative Agent, a Lender or an Issuing Bank as to the amount of such payment or liability under this Section 5.03 shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall also indemnify the Administrative Agent, within ten (10) days after demand therefor, for any amount which a Lender or the Issuing Bank for any reason fails to pay indefeasibly to the Administrative Agent as required by paragraph (g) below; provided that (i) the Borrower shall not be required to indemnify the Administrative Agent pursuant to this sentence to the extent that any such amount paid or payable as required by such paragraph (g) is a direct result of the Administrative Agent’s gross negligence or willful misconduct, and (ii) such Lender or Issuing Bank, as the case may be, shall indemnify the Borrower to the extent of any such payment the Borrower makes to the Administrative Agent pursuant to this sentence.

(d)                                 Evidence of Payments.  As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower or a Guarantor to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e)                                  Status of Lenders; Tax Documentation.  (i)  Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement or any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate. 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. Without limiting the generality of the foregoing, in the event that the Borrower is a resident for tax purposes in the United States, any Foreign Lender shall deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request of the Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable:

63

(A)      duly completed copies of IRS Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States is a party;

(B)        duly completed copies of IRS Form W-8ECI;

(C)        in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of IRS Form W-8BEN; 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.

(ii)                                  Any Lender that is a “United States person” within the meaning of Section 7701(a)(30) of the Code shall deliver to the Borrower and the Administrative Agent executed originals of Internal Revenue Service Form W-9 or such other documentation or information prescribed by applicable Laws or reasonably requested by the Borrower or the Administrative Agent certifying, to the extent such Lender is legally entitled to do so, that such Lender is not subject to backup withholding tax requirements.

(iii)                               If a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment.  Solely for purposes of this clause (iii), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(f)                                    Tax Refunds.  If the Administrative Agent or a Lender determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 5.03, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 5.03 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay

64

the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority.  Notwithstanding anything to the contrary in this paragraph (f), in no event will the Administrative Agent or any Lender be required to pay any amount to an indemnifying party pursuant to this paragraph (f) the payment of which would place the Administrative Agent or Lender in a less favorable net after-Tax position than the Administrative Agent or Lender would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This Section 5.03 shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

(g)                                 Indemnification of the Administrative Agent.  Each Lender shall indemnify the Administrative Agent within ten (10) days after demand therefor, for the full amount of any Excluded Taxes attributable to such Lender that are payable or paid by the Administrative Agent, and reasonable expenses arising therefrom or with respect thereto, whether or not such Excluded Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority.  A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error.  Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender, as the case may be, under any Loan Document against any amount due to the Administrative Agent under this paragraph (g). The agreements of this paragraph (g) shall survive the resignation and/or replacement of the Administrative Agent.

(h)                                 Survival.  Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower, each Lender and the Issuing Bank contained in this Section shall survive the payment in full of the Obligations and the termination of the Commitments until the expiration of the applicable statute of limitations.

Section 5.04                            Mitigation Obligations; Replacement of Lenders.

(a)                                  Designation of Different Lending Office.  If any Lender requests compensation under Section 5.01, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 5.01 or Section 5.03, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender.  The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b)                                 Replacement of Lenders.  If (i) any Lender requests compensation under Section 5.01, (ii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, (iii) any Lender becomes a Defaulting Lender, (iv) any Lender declines to make a Eurodollar Loan under

65

Section 5.05, or (v) any Lender becomes a Non-Consenting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 12.04(b)), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, and (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts).

Section 5.05                            Illegality.  Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its applicable lending office to honor its obligation to make or maintain Eurodollar Loans either generally or having a particular Interest Period hereunder, then (a) such Lender shall promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to make such Eurodollar Loans shall be suspended (the “Affected Loans”) until such time as such Lender may again make and maintain such Eurodollar Loans and (b) all Affected Loans which would otherwise be made by such Lender shall be made instead as ABR Loans (and, if such Lender so requests by notice to the Borrower and the Administrative Agent, all Affected Loans of such Lender then outstanding shall be automatically converted into ABR Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) ABR Loans, all payments of principal which would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its ABR Loans.

72

Property and the conduct of its business, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

(b)                                 Neither the Borrower nor any Restricted Subsidiary is in default nor has any event or circumstance occurred which, but for the expiration of any applicable grace period or the giving of notice, or both, would constitute a default or would require the Borrower or a Restricted Subsidiary to Redeem or make any offer to Redeem under any indenture, note, credit agreement or instrument pursuant to which any Material Indebtedness is outstanding or by which the Borrower or any Restricted Subsidiary or any of their Properties is bound.

(f)                                    Neither the Borrower, the Restricted Subsidiaries nor any ERISA Affiliate sponsors, maintains or contributes to, or has at any time in the six-year period preceding the date hereof sponsored, maintained or contributed to, any Multiemployer Plan.

Section 7.12                            Insurance.  The Borrower has, and has caused all of its Restricted Subsidiaries to have, (a) all insurance policies sufficient for the compliance by each of them with

74

all material Governmental Requirements and all material agreements and (b) insurance coverage in at least amounts and against such risk (including, without limitation, public liability) that are usually insured against by companies similarly situated and engaged in the same or a similar business for the assets and operations of the Borrower and its Restricted Subsidiaries.  The Administrative Agent and the Lenders have been named as additional insureds in respect of such liability insurance policies, and the Administrative Agent has been named as loss payee with respect to Property loss insurance.  No mortgaged building, plant, terminal or other surface property is located in a special flood hazard area as designated by any Governmental Authority, except to the extent flood insurance is in force with respect to such portion.

(b)                                 After giving full effect to the Excepted Liens, the Borrower or the Restricted Subsidiary specified as the owner of the Upstream Component Properties owns the net interests in Hydrocarbon production attributable to the Upstream Component Properties as reflected in the most recently delivered Reserve Report, and the ownership of such Upstream Component Properties shall not in any material respect obligate the Borrower or such Restricted Subsidiary to bear the costs and expenses relating to the maintenance, development and operations of each such Upstream Component Property in an amount in excess of the working interest of each Upstream Component Property set forth in the most recently delivered Reserve Report that is not offset by a corresponding proportionate increase in the Borrower’s or such Restricted Subsidiary’s net revenue interest in such Upstream Component Property.

(c)                                  The Borrower and its Restricted Subsidiaries own the Midstream Properties that generated the Midstream EBITDA used in the most recent calculation of the Midstream Component as may be adjusted pursuant to Section 2.08(b)(iii), except for Midstream Properties Disposed of since the most recent calculation of the Midstream Component that do not meet the thresholds provided by Section 2.08(b)(iii) with respect to the Disposition of such Midstream Properties.

(f)                                    All of the Properties of the Borrower and the Restricted Subsidiaries which are reasonably necessary for the operation of their businesses are in good working condition and are maintained in accordance with prudent business standards except where the failure to do so could not reasonably be expected to have a Material Adverse Effect.

(g)                                 The Borrower and each Restricted Subsidiary owns, or is licensed to use, all trademarks, tradenames, copyrights, patents and other intellectual Property material to its business, and the use thereof by the Borrower and such Restricted Subsidiary does not infringe upon the rights of any other Person, except for any such infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.  The Borrower and its Restricted Subsidiaries either own or have valid licenses or other rights to use all databases, geological data, geophysical data, engineering data, seismic data, maps, interpretations and other technical information used in their businesses as presently conducted, subject to the limitations contained in the agreements governing the use of the same, which limitations are customary for companies engaged in the business of the exploration and

86

there are no gas imbalances, take or pay or other prepayments in excess of the volume specified in Section 7.18 with respect to its Oil and Gas Borrowing Base Properties which would require the Borrower or any Restricted Subsidiary to deliver Hydrocarbons either generally or produced from such Oil and Gas Borrowing Base Properties at some future time without then or thereafter receiving full payment therefor, (iii) none of their Upstream Component Properties have been sold since the date of the last Upstream Component determination except as set forth on an exhibit to the certificate, which certificate shall list all of its Upstream Component Properties sold and in such detail as reasonably required by the Administrative Agent, (iv) attached to the certificate is a list of all marketing agreements entered into subsequent to the later of the date hereof or the most recently delivered Reserve Report which the Borrower could reasonably be expected to have been obligated to list on Schedule 7.19 had such agreement been in effect on the date hereof, and (v) attached thereto is a schedule of the Upstream Component Properties that are Mortgaged Properties and demonstrating the percentage of the total value of the Upstream Component Properties that the value of such Mortgaged Properties represent in compliance with Section 8.14(a).

Section 8.13                            Title Information.

(a)                                  On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Section 8.12(a), the Borrower will deliver title information in form and substance acceptable to the Administrative Agent covering enough of the Upstream Component Properties that were not included in the immediately preceding Reserve Report, so that the Administrative Agent shall have received together with title information previously delivered to the Administrative Agent, satisfactory title information on at least 80% of the total value of the Upstream Component Properties as set forth in such Reserve Report.

(b)                                 If the Borrower has provided title information for additional Upstream Component Properties under Section 8.13(a), the Borrower shall, within sixty (60) days of notice from the Administrative Agent that title defects or exceptions exist with respect to such additional Upstream Component Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as to priority) which are not permitted by Section 9.03 raised by such information, or (ii) deliver title information for Upstream Component Properties not previously reviewed in form and substance acceptable to the Administrative Agent so that the Administrative Agent shall have received, together with title information previously delivered to the Administrative Agent, satisfactory title information on at least 80% of the value of the Upstream Component Properties as set forth in the most recent Reserve Report.

(c)                                  If the Borrower is unable to cure any title defect requested by the Administrative Agent or the Lenders to be cured within the 60-day period or the Borrower does

87

not comply with the requirements to provide acceptable title information covering 80% of the value of the Upstream Component Properties as set forth in the most recent Reserve Report, such default shall not be a Default, but instead the Administrative Agent shall have the right to exercise the following remedy in its sole discretion from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as to future exercise of the remedy by the Administrative Agent.  To the extent that the Administrative Agent are not satisfied with title to any Upstream Component Property after the 60-day period has elapsed, such unacceptable Mortgaged Property shall not count towards the 80% requirement, and the Administrative Agent may send a notice to the Borrower and the Lenders that the then outstanding Upstream Component shall be reduced by an amount as determined by the Administrative Agent to cause the Borrower to be in compliance with the requirement to provide acceptable title information on 80% of the value of the Upstream Component Properties as set forth in the most recent Reserve Report.  This new Upstream Component shall become effective immediately after receipt of such notice.

Section 8.14                            Additional Collateral; Additional Guarantors.

(a)                                  In connection with each Upstream Component Redetermination, the Borrower shall review the Reserve Report and the list of current Mortgaged Properties (as described in Section 8.12(c)(iii)) to ascertain whether the Mortgaged Properties represent at least 80% of the total value of the Upstream Component Properties as set forth in such Reserve Report after giving effect to exploration and production activities, acquisitions, Dispositions and production.  In the event that the Mortgaged Properties do not represent at least 80% of such total value, then the Borrower shall, and shall cause its Restricted Subsidiaries to, grant, within thirty (30) days of delivery of the certificate required under Section 8.12(c), to the Administrative Agent as security for the Secured Obligations a first-priority Lien (provided that Excepted Liens of the type described in clauses (a) to (d) and (f) of the definition thereof may exist, but subject to the provisos at the end of such definition) on additional Upstream Component Properties not already subject to a Lien of the Security Instruments such that after giving effect thereto, the Mortgaged Properties will represent at least 80% of such total value.  All such Liens will be created and perfected by and in accordance with the provisions of deeds of trust, security agreements and financing statements or other Security Instruments, all in form and substance reasonably satisfactory to the Administrative Agent and in sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording purposes.  In order to comply with the foregoing, if any Restricted Subsidiary places a Lien on its Upstream Properties and such Restricted Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with Section 8.14(b).

(b)                                 In the event that (i) the Borrower or any Restricted Subsidiary acquires any Material Domestic Subsidiary, (ii) the Borrower determines that any Restricted Subsidiary is a Material Domestic Subsidiary or (iii) any Domestic Subsidiary incurs or guarantees any Indebtedness, the Borrower shall promptly (and in any event within thirty (30) days of such acquisition, determination, incurrence or guaranty) cause such Restricted Subsidiary to guarantee the Secured Obligations pursuant to the Guaranty and Collateral Agreement.  In connection with any guaranty, the Borrower shall, or shall cause such Domestic Subsidiary to, (A) execute and deliver a supplement to the Guaranty and Collateral Agreement executed by such Domestic Subsidiary, (B) cause the owner of the Equity Interests in such Domestic Subsidiary to pledge

88

such Equity Interests (including, without limitation, to the extent certificated, delivery of original stock certificates evidencing the Equity Interests of such Domestic Subsidiary, together with an appropriate undated stock powers for each certificate duly executed in blank by the registered owner thereof) and (C) execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent.

(c)                                  In the event that the Borrower or any Domestic Subsidiary becomes the owner of a Foreign Subsidiary, then the Borrower shall promptly, or shall cause such Domestic Subsidiary to promptly (and in any event within thirty (30) days after such acquisition or formation) (i) execute and deliver a supplement to the Guaranty and Collateral Agreement, (ii) pledge 66% of all the Equity Interests of such Foreign Subsidiary (including, without limitation, to the extent certificated, delivery of original stock certificates evidencing such Equity Interests of such Foreign Subsidiary, together with appropriate stock powers for each certificate duly executed in blank by the registered owner thereof), so long as such pledge does not result in adverse tax consequences to the Borrower or such Domestic Subsidiary, and (iii) execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent.

(d)                                 The Borrower will at all times cause the other material tangible and intangible Property of the Borrower and each Restricted Subsidiary not covered by clauses (a) through (c) above to be subject to a Lien pursuant to the Security Instruments; provided, that in the case of a Permitted Acquisition, the Borrower and the applicable Restricted Subsidiaries shall have thirty (30) days (subject to extension in the sole discretion of the Administrative Agent) in which to satisfy this Section 8.14(d); provided further, that if the Administrative Agent determines, in its sole discretion, that the cost of obtaining a Lien on any such other material tangible or intangible Property is excessive in relation to the value afforded thereby, the Administrative Agent may waive the requirements of this Section 8.14(d) with respect to such Property.

(e)                                  The Liens on such Mortgaged Properties shall exclude “Buildings” (as defined in 39 C.F.R. § 339.2, as such may be amended from time to time) except with respect to material Buildings required by the Administrative Agent to be subject to a Lien, in which case, with respect to each such material Building (each a “Mortgaged Building”) which is located in a “flood hazard area,” as indicated on the Flood Insurance Rate Map published by the Federal Emergency Management Agency (or any successor agency), as such map may be revised from time to time, Borrower will, upon written notice by Administrative Agent, obtain flood insurance with respect to such Mortgaged Building under the National Flood Insurance Program (“NFIP”), if such insurance is available, in such amount as Administrative Agent may from time to time reasonably require, not to exceed, however, the maximum coverage available to Borrower under the NFIP.

Section 9.01                            Financial Covenants.

(a)                                  Interest Coverage Ratio.  The Borrower will not, as of the last day of any fiscal quarter, permit the ratio of Consolidated EBITDA for the period of four (4) fiscal quarters then ending to Consolidated Interest Expense for such period to be less than 2.50 to 1.00.

(d)                                 Certain Calculations.  With respect to any period during which (i) a recalculation of Midstream EBITDA has been made pursuant to Section 2.08(b)(iii) or (ii) an asset acquisition, Permitted Acquisition, Disposition, or redesignation of a Subsidiary as either an Unrestricted Subsidiary or a Restricted Subsidiary having , in each case of this clause (ii), a fair market value in excess of $20,000,000, has occurred (each, a “Subject Transaction”), for purposes of determining compliance with the financial covenants set forth in this Section 9.01 and for purposes of determining Midstream EBITDA as used in Section 2.08(b)(ii), Consolidated EBITDA shall be calculated with respect to such period on a pro forma basis (including pro forma adjustments arising out of events which are directly attributable to a Subject Transaction, are factually supportable and are expected to have a continuing impact, in each case, determined on a basis consistent with Article 11 of Regulation S-X promulgated under the Securities Act of 1933 and as interpreted by the staff of the SEC, which would include cost savings resulting from head count reduction, closure of facilities and similar restructuring charges, which pro forma adjustments shall be certified by the chief financial officer of the Ultimate General Partner) using historical financial statements (audited, if available) applicable to the subject of such Subject Transaction and the consolidated financial statements of the Borrower and its Subsidiaries which shall be reformulated as if such Subject Transaction, and any Indebtedness incurred or repaid in connection therewith, had been consummated or incurred or repaid at the beginning of such period (and assuming that such Indebtedness bears interest during any portion of the applicable measurement period prior to the relevant acquisition at the weighted average of the interest rates applicable to outstanding Loans incurred during such period).

(e)                                  Material Projects.

(i)                                     With respect to any Material Project, the following adjustments (the “Material Project EBITDA Adjustments”) may be made, at the Borrower’s discretion, to Consolidated EBITDA:

91

volumes, a percentage (based on the then-current completion percentage of such Material Project as of the date of determination) of an amount to be approved by the Administrative Agent as the projected Consolidated EBITDA attributable to such Material Project for the first 12-month period following the scheduled Commercial Operation Date of such Material Project (such amount to be determined based upon projected revenues from customer contracts, projected revenues that are determined by the Administrative Agent, in its discretion, to otherwise be highly probable, the creditworthiness and applicable projected production of the prospective customers, capital and other costs, operating and administrative expenses, scheduled Commercial Operation Date, commodity price assumptions and other factors deemed appropriate by the Administrative Agent), may be added, at the Borrower’s option, to actual Consolidated EBITDA for the fiscal quarter in which construction or expansion of such Material Project commences and for each fiscal quarter thereafter until the Commercial Operation Date of such Material Project (including the fiscal quarter in which such Commercial Operation Date occurs, but net of any actual Consolidated EBITDA attributable to such Material Project following such Commercial Operation Date); provided that if the actual Commercial Operation Date does not occur by the scheduled Commercial Operation Date, then the foregoing amount shall be reduced for quarters ending after the scheduled Commercial Operation Date to (but excluding) the first full quarter after the actual Commercial Operation Date, by the following percentage amounts depending on the period of delay (based on the period of actual delay or then-estimated delay, whichever is longer):  (1) 60 days or less, 0%, (2) longer than 60 days, but not more than 90 days, 50%, and 3) longer than 90 days, 100%; and

(B)                                beginning with the first full fiscal quarter following the Commercial Operation Date of such Material Project and for the two (2) immediately succeeding fiscal quarters, an amount equal to the projected Consolidated EBITDA attributable to such Material Project for the balance of the four (4) full fiscal quarter period following such Commercial Operation Date, may be added, at the Borrower’s option, to actual Consolidated EBITDA for such fiscal quarters.

(ii)                                  Notwithstanding anything else contained in this Section 9.01(e):

(A)                              no Material Project EBITDA Adjustment shall be allowed with respect to any Material Project unless at least thirty (30) days prior to the last day of the fiscal quarter for which the Borrower desires to commence inclusion of such Material Project EBITDA Adjustment in Consolidated EBITDA with respect to a Material Project (the “Initial Quarter”), the Borrower shall have delivered to the Administrative Agent written pro forma projections of Consolidated EBITDA attributable to such Material Project and such other documentation as the Administrative Agent may reasonably request, all in form and substance satisfactory to the Administrative Agent,

92

(B)                                no Material Project EBITDA Adjustment shall be allowed with respect to any Material Project unless prior to the last day of the Initial Quarter, the Administrative Agent shall have approved (such approval not to be unreasonably withheld) such projections and shall have received such other information and documentation as the Administrative Agent may reasonably request, all in form and substance satisfactory to the Administrative Agent,

(C)                                the aggregate amount of all Material Project EBITDA Adjustments with respect to a particular Material Project shall not exceed twenty percent (20%) of the capital cost of such Material Project, and

(D)                               the aggregate amount of all Material Project EBITDA Adjustments during any period shall be limited to ten percent (10%) of the total actual Consolidated EBITDA for such period (which total actual Consolidated EBITDA shall be determined without including any Material Project EBITDA Adjustments).
