(e)                                  Each prepayment of principal under this section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid.  Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment.

Section 2.12                             Fees.

(a)                                 Borrower agrees to pay to the Administrative Agent, for the account of each Lender, an unused commitment fee (the “Unused Commitment Fee”) equal to the Applicable Rate for Unused Commitment Fees times the daily average of the Aggregate Unused Commitment.  Such Unused Commitment Fee shall be calculated on the basis of a year consisting of 360 days.  The Unused Commitment Fee shall be payable in arrears on the last day of March, June, September and December of each year, commencing with the first such date to occur after the Effective Date, and on the Maturity Date for any period then ending for which the Unused Commitment Fee shall not have been theretofore paid.  In the event the Aggregate Commitment terminates on any date other than the last day of March, June, September or December of any year, Borrower agrees to pay to the Administrative Agent, for the account of each Lender, on the date of such termination, the pro rata portion of the Unused Commitment Fee due for the period from the last day of the immediately preceding March, June, September or December, as the case may be, to the date such termination occurs.

(b)                                 Reserved.

(c)                                  Reserved.

(d)                                 All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent for distribution, in the case of Unused Commitment Fees, to the Lenders.  Fees paid shall not be refundable under any circumstances.

Section 2.13                             Interest.

(a)                                 The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Rate.

(b)                                 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 Rate.

35

(c)                                  Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, two percent (2%) plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section or (ii) in the case of any other amount, two percent (2%) plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section.

(d)                                 Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Aggregate Commitment and on the Maturity Date; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Loan prior to the end of the Availability Period at a time when no Borrowing Base Deficiency exists), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(e)                                  All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day).  The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

Section 2.14                             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 (including, without limitation, by means of an Interpolated Rate) the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

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

then the Administrative Agent shall give notice thereof to Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies 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

36

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 2.15                             Increased Costs.

(a)                                 If any Change in Law shall:

(i)                                     impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate); or

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

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or otherwise), then Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

(b)                                 If any Lender determines that any Change in Law regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement or the Loans made by such Lender, to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy and liquidity), then from time to time Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

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

(d)                                 Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation; provided that Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender notifies Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or

37

reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 2.16                             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 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 (regardless of whether such notice may be revoked under Section 2.10(b) and is revoked in accordance therewith) 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 Borrower pursuant to Section 2.19, then, in any such event, 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 shall be delivered to Borrower and shall be conclusive absent manifest error.  Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

Section 2.17                             Taxes.

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

(b)                                 In addition, Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c)                                  Borrower shall indemnify the Administrative Agent and each Lender 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 on or with respect to any payment by or on account of any obligation of Borrower hereunder (including

38

Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) 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 as to the amount of such payment or liability delivered to Borrower by a Lender or by the Administrative Agent on its own behalf or on behalf of a Lender shall be conclusive absent manifest error.

(d)                                 As soon as practicable after any payment of Indemnified Taxes or Other Taxes by Borrower to a Governmental Authority, 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)                                  Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by Borrower as will permit such payments to be made without withholding or at a reduced rate.

(f)                                   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 Borrower or with respect to which Borrower have paid additional amounts pursuant to this Section 2.17, it shall pay over such refund to Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by Borrower under this Section 2.17 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 Borrower, upon the request of the Administrative Agent or such Lender, agree to repay the amount paid over to Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This Section 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 Borrower or any other Person.

(g)                                  In the case of a Lender that would be subject to withholding tax imposed by FATCA on payments made on account of any obligation of Borrower hereunder if such Lender fails 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 provide 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 Borrower or the Administrative Agent as may be necessary for

39

Borrower or the Administrative Agent to comply with their obligations under FATCA, to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from any such payments.

Section 2.18                             Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a)                                 Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, or fees, or of amounts payable under Section 2.15, Section 2.16 or Section 2.17, or otherwise) prior to 12:00 noon on the date when due, in immediately available funds, without set-off or counterclaim.  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 at Mail Code IL1-0010, 10 South Dearborn, Chicago, Illinois, 60603-2003, and except that payments pursuant to Section 2.15, Section 2.16, Section 2.17 and Section 11.03 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)                                 If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest, fees and other Obligations 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 then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties; provided that, notwithstanding anything to the contrary contained in this Agreement or in any other Loan Document, in the event such funds are received by and available to the Administrative Agent as a result of the exercise of any rights and remedies with respect to any collateral under the Security Documents or as a result of any distribution made pursuant to a bankruptcy proceeding of any Credit Party or any plan of reorganization confirmed in any such proceeding, such funds shall be applied (A) first and ratably to any fees and reimbursements due Administrative Agent hereunder or under any other Loan Document and the Antero Resources Agent under any Antero Resources Loan Document, (B) then ratably to the payment of the Obligations (other than Cash Management Obligations) and the Antero Resources Obligations (other than Cash Management Obligations under and as defined in the Antero Resources Credit Agreement), including unreimbursed LC Disbursements and the Lender Hedging Obligations and the “Lender Hedging Obligations” under and as defined in the Antero Resources Credit Agreement, in each case, until such Obligations and the Antero Resources Obligations are paid in full, and (C) then ratably to the payment of Cash Management Obligations and the “Cash Management Obligations” under and as defined in the Antero Resources Credit Agreement.  Notwithstanding the foregoing, amounts received from any Credit Party that

40

is not an Eligible Contract Participant shall not be applied to any Excluded Swap Obligations owing to a Lender Counterparty (it being understood, that in the event that any amount is applied to Obligations other than Excluded Swap Obligations as a result of this clause, the Administrative Agent shall make such adjustments as it determines are appropriate to distributions pursuant to the foregoing clause (B) from amounts received from Eligible Contract Participants to ensure, as nearly as possible, that the proportional aggregate recoveries with respect to Obligations described in the foregoing clause (B) above by Lender Counterparties that are the holders of any Excluded Swap Obligations are the same as the proportional aggregate recoveries with respect to other Obligations pursuant to the foregoing clause (B) above).  The Administrative Agent shall have no responsibility to determine the existence or amount of Lender Hedging Obligations or Cash Management Obligations and may reserve from the application of amounts under this Section amounts distributable in respect of Lender Hedging Obligations or Cash Management Obligations until it has received evidence satisfactory to it of the existence and amount of such Lender Hedging Obligations or Cash Management Obligations.

(c)                                  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 resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its 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 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; 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 paragraph shall not be construed to apply to any payment made by 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 to any assignee or participant, other than to Borrower or any Subsidiary thereof (as to which the provisions of this paragraph shall apply).  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 such Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

(d)                                 Unless the Administrative Agent shall have received notice from Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that Borrower will not make such payment, the Administrative Agent may assume that Borrower have made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due.  In such event, if Borrower have not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of

41

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.

(e)                                  Notwithstanding anything to the contrary herein, if any Lender shall fail to make any payment required to be made by it pursuant to Section 2.07(b), Section 2.18(d) or Section 11.03(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), (i) 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, and/or (ii) hold any such amounts in a segregated account as cash collateral for, and application to, any funding obligations of such Lender under any such Section, in the case of each of clauses (i) and (ii) above, in any order as determined by the Administrative Agent in its discretion.

Section 2.19                             Mitigation Obligations; Replacement of Lenders.

(a)                                 If any Lender requests compensation under Section 2.15, or if Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, 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 2.15 or Section 2.17, 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.  Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b)                                 If any Lender requests compensation under Section 2.15, or if Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, then 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 11.04), 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) Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, 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 Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result in a reduction in such compensation or payments.  A Lender shall not be required to make any such assignment and delegation if, prior thereto,

42

as a result of a waiver by such Lender or otherwise, the circumstances entitling Borrower to require such assignment and delegation cease to apply.

(c)                                  If (i) in connection with any proposed amendment, modification, termination, waiver or consent with respect to any of the provisions of this Agreement or any other Loan Document that requires approval of all of the Lenders, each Lender or each Lender affected thereby under Section 11.02, the consent of the Required Lenders shall have been obtained but the consent of one or more such other Lenders (each a “Non-Consenting Lender”) whose consent is required has not been obtained, or (ii) any Lender becomes a Defaulting Lender; then Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, elect to replace such Non-Consenting Lender or Defaulting Lender, as the case may be, as a Lender party to this Agreement in accordance with and subject to the restrictions contained in, and consents required by Section 11.04; provided that (x) Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, and (y) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, 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 Borrower (in the case of all other amounts).  A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a consent by such Lender or otherwise, the circumstances entitling Borrower to require such assignment and delegation cease to apply or, in the case of a Defaulting Lender, such Lender is no longer a Defaulting Lender.

Section 2.20                             Reserved.

Section 2.21                             Reserved.

Section 2.22                             Defaulting Lenders.  Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender.

(a)                                 Fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender pursuant to Section 2.12(a).

(b)                                 The Commitment and Credit Exposure of such Defaulting Lender shall not be included in determining whether all Lenders, the Required Lenders or the Majority Lenders have taken or may take any action hereunder (including any consent to any amendment, waiver or other modification pursuant to Section 11.02), provided that (i) any waiver, consent, amendment or modification requiring the consent of such Lender or each affected Lender shall require the consent of such Defaulting Lender, (ii) any waiver, consent, amendment or modification requiring the consent of each Lender shall require the consent of such Defaulting Lender (except in respect of any increases in the Borrowing Base or the Maximum Facility Amount), and (iii) the Commitment of such Defaulting Lender may not be increased or extended without the consent of such Defaulting Lender.

43

In the event that the Administrative Agent and Borrower each agree that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then such Lender shall purchase at par such of the Loans of the other Lenders as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Applicable Percentage.

Section 4.12                             Labor Matters.  There are no strikes, lockouts or slowdowns against Borrower or any of its Restricted Subsidiaries pending or, to the knowledge of Borrower, threatened that could reasonably be expected to have a Material Adverse Effect.  The hours

worked by and payments made to employees of Borrower and its Restricted Subsidiaries have not been in violation of the Fair Labor Standards Act or any other Law dealing with such matters to the extent that such violation could reasonably be expected to have a Material Adverse Effect.

Section 4.13                             Capitalization.  Schedule 4.13 lists, as of the Effective Date, (a) each Subsidiary that is an Unrestricted Subsidiary, (b) for Borrower, its full legal name, its jurisdiction of organization and its federal tax identification number, and (c) for each Restricted Subsidiary, its full legal name, its jurisdiction of organization, its federal tax identification number and the number of shares of capital stock or other Equity Interests outstanding and the owner(s) of such shares or Equity Interests.  As of the Effective Date except for the Midstream Special Interests, Antero owns all of the issued and outstanding Equity Interests of Borrower.

Section 4.17                             Solvency.

(a)                                 Immediately after the consummation of the Transactions and immediately following the making of the initial Borrowing, if any, made on the Effective Date and after giving effect to the application of the proceeds thereof, (1) the fair value of the assets of the Credit Parties on a combined basis, at a fair valuation, will exceed the debts and liabilities, subordinated, contingent or otherwise, of the Credit Parties on a combined basis; (2) the present fair saleable value of the real and personal property of the Credit Parties on a combined basis will be greater than the amount that will be required to pay the probable liability of the Credit Parties on a combined basis on their debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured; (3) the Credit Parties on a combined basis will be able to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured; and (4) the Credit Parties on a combined basis will not have unreasonably small capital with which to conduct the businesses in which

they are engaged as such businesses are now conducted and are proposed to be conducted after the date hereof.

Section 4.18                             Leases and Contracts; Performance of Obligations.  Borrower has not received a written notice of default under any leases, contracts, and other agreements that remains uncured that could reasonably be expected to result in a Material Adverse Effect.  Except for any rents, royalties and other payments that in the aggregate do not exceed $1,000,000 or are being contested in compliance with Section 6.04, all rents, royalties and other payments due and payable under such leases, contracts, servitudes and other agreements, or under any Permitted Liens, or otherwise attendant to the ownership or operation of any Midstream Assets, have been properly and timely paid.  No Credit Party has received written notice of a default that remains uncured with respect to its obligations (and no Credit Party has received written notice of any default by any third party with respect to such third party’s obligations) under any such leases, contracts, servitudes and other agreements, or under any Permitted Liens, or otherwise attendant to the ownership or operation of any part of the Midstream Assets, where such default could reasonably be expected to materially and adversely affect the ownership or operation of such Midstream Assets.  No Credit Party is currently accounting for any royalties, or overriding royalties or other payments out of production, on a basis (other than delivery in kind) less favorable to such Credit Party than proceeds received by such Credit Party (calculated at the well) from sale of production, and no Credit Party has any liability (or alleged liability) to account for the same on any such less favorable basis that could reasonably be expected to result in a Material Adverse Effect.

Section 4.19                             Anti-Corruption Laws and Sanctions.  Each Credit Party has implemented and maintains in effect policies and procedures designed to ensure compliance by such Credit Party, its Subsidiaries and their respective directors, officers, employees and agents with Anti-Corruption Laws and applicable Sanctions, and such Credit Party, its Subsidiaries and their respective officers and employees and, to the knowledge of such Credit Party, its directors and agents, are in compliance with Anti-Corruption Laws and applicable Sanctions in all material respects.  None of (a) any Credit Party, any Subsidiary or any of their respective directors, officers or employees, or (b) to the knowledge of any such Credit Party or Subsidiary, any agent of such Credit Party or any Subsidiary that will act in any capacity in connection with or benefit from the credit facility established hereby, is a Sanctioned Person.   No Borrowing, use of proceeds, Transaction or other transaction contemplated by this Agreement or the other Loan Documents will violate Anti-Corruption Laws or applicable Sanctions.

ARTICLE VIII
Guarantee of Obligations

Section 8.01                             Guarantee of Payment.  Each Guarantor unconditionally and irrevocably guarantees to the Administrative Agent for the benefit of the Secured Parties, the punctual payment of all Obligations now or which may in the future be owing by any Credit Party (the “Guaranteed Liabilities”).  This Guarantee is a guaranty of payment and not of collection only.  The Administrative Agent shall not be required to exhaust any right or remedy or take any action against Borrower or any other Person or any collateral.  The Guaranteed Liabilities include interest accruing after the commencement of a proceeding under bankruptcy, insolvency or similar laws of any jurisdiction at the rate or rates provided in the Loan Documents, or the Hedging Contracts between any Credit Party and any Secured Party, as the case may be, regardless of whether such interest is an allowed claim.  Each Guarantor agrees that, as between the Guarantor and the Administrative Agent, the Guaranteed Liabilities may be declared to be due and payable for the purposes of this Guarantee notwithstanding any stay, injunction or other prohibition which may prevent, delay or vitiate any declaration as regards Borrower or any other Guarantor and that in the event of a declaration or attempted declaration, the Guaranteed Liabilities shall immediately become due and payable by each Guarantor for the purposes of this Guarantee.

Section 8.02                             Guarantee Absolute.  Each Guarantor guarantees that the Guaranteed Liabilities shall be paid strictly in accordance with the terms of this Agreement and the Hedging Contracts.  The liability of each Guarantor hereunder is absolute and unconditional irrespective of:  (a) any change in the time, manner or place of payment of, or in any other term of, all or any of the Loan Documents or the Guaranteed Liabilities, or any other amendment or waiver of or any consent to departure from any of the terms of any Loan Document or Guaranteed Liability, including any increase or decrease in the rate of interest thereon; (b) any release or amendment or waiver of, or consent to departure from, any other guaranty or support document, or any exchange, release or non-perfection of any collateral, for all or any of the Loan Documents or Guaranteed Liabilities; (c) any present or future law, regulation or order of any jurisdiction (whether of right or in fact) or of any agency thereof purporting to reduce, amend, restructure or otherwise affect any term of any Loan Document or Guaranteed Liability; (d) without being limited by the foregoing, any lack of validity or enforceability of any Loan Document or Guaranteed Liability; and (e) any other setoff, defense or counterclaim whatsoever (in any case, whether based on contract, tort or any other theory) with respect to the Loan Documents or the transactions contemplated thereby which might constitute a legal or equitable defense available to, or discharge of, Borrower or a Guarantor.

Section 8.03                             Guarantee Irrevocable.  This Guarantee is a continuing guaranty of the payment of all Guaranteed Liabilities now or hereafter existing under this Agreement and the Hedging Contracts and shall remain in full force and effect until payment in full of all Guaranteed Liabilities and other amounts payable hereunder and until this Agreement and the Hedging Contracts are no longer in effect or, if earlier, when the Guarantor has given the Administrative Agent written notice that this Guarantee has been revoked; provided that any notice under this Section shall not release the revoking Guarantor from any Guaranteed Liability, absolute or contingent, existing prior to the Administrative Agent’s actual receipt of the notice at

59

its branches or departments responsible for this Agreement and the Hedging Contracts and reasonable opportunity to act upon such notice.

Section 8.04                             Reinstatement.  This Guarantee shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Liabilities is rescinded or must otherwise be returned by any Secured Party on the insolvency, bankruptcy or reorganization of Borrower or any other Credit Party, or otherwise, all as though the payment had not been made.

Section 8.05                             Subrogation.  No Guarantor shall exercise any rights which it may acquire by way of subrogation, by any payment made under this Guarantee or otherwise, until all the Guaranteed Liabilities have been paid in full and this Agreement and the Hedging Contracts are no longer in effect.  If any amount is paid to the Guarantor on account of subrogation rights under this Guarantee at any time when all the Guaranteed Liabilities have not been paid in full, the amount shall be held in trust for the benefit of the Secured Parties and shall be promptly paid to the Administrative Agent to be credited and applied to the Guaranteed Liabilities, whether matured or unmatured or absolute or contingent, in accordance with the terms of this Agreement and the Hedging Contracts.  If any Guarantor makes payment to any Secured Party of all or any part of the Guaranteed Liabilities and all the Guaranteed Liabilities are paid in full and this Agreement and the Hedging Contracts are no longer in effect, such Secured Party shall, at such Guarantor’s request, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Guaranteed Liabilities resulting from the payment.

Section 8.06                             Subordination.  Without limiting the rights of the Secured Parties under any other agreement, any liabilities owed by Borrower to any Guarantor in connection with any extension of credit or financial accommodation by any Guarantor to or for the account of Borrower, including but not limited to interest accruing at the agreed contract rate after the commencement of a bankruptcy or similar proceeding, are hereby subordinated to the Guaranteed Liabilities, and such liabilities of Borrower to such Guarantor, if the Administrative Agent so requests, shall be collected, enforced and received by any Guarantor as trustee for the Administrative Agent and shall be paid over to the Administrative Agent on account of the Guaranteed Liabilities but without reducing or affecting in any manner the liability of the Guarantor under the other provisions of this Guarantee.

Section 8.07                             Setoff.  Each Guarantor agrees that, in addition to (and without limitation of) any right of setoff, banker’s lien or counterclaim the Administrative Agent, any Lender or any Lender Counterparty may otherwise have, the Administrative Agent, such Lender or such Lender Counterparty shall be entitled, at its option, to offset balances (general or special, time or demand, provisional or final) held by it for the account of any Guarantor at any office of the Administrative Agent, such Lender or such Lender Counterparty, in Dollars or in any other currency, against any amount payable by such Guarantor under this Guarantee which is not paid when due (regardless of whether such balances are then due to such Guarantor), in which case it shall promptly notify such Guarantor thereof; provided that the failure of the Administrative Agent, such Lender, or such Lender Counterparty to give such notice shall not affect the validity thereof.

60

Section 8.08                             Formalities.  Each Guarantor waives presentment, notice of dishonor, protest, notice of acceptance of this Guarantee or incurrence of any Guaranteed Liability and any other formality with respect to any of the Guaranteed Liabilities or this Guarantee.

Section 8.09                             Limitations on Guarantee.  The provisions of the Guarantee under this Article VIII are severable, and in any action or proceeding involving any state corporate law, or any state, federal or foreign bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of any Guarantor under this Guarantee would otherwise be held or determined to be avoidable, invalid or unenforceable on account of the amount of such Guarantor’s liability under this Guarantee, then, notwithstanding any other provision of this Guarantee to the contrary, the amount of such liability shall, without any further action by the Guarantors, the Administrative Agent, any Lender or any Lender Counterparty, be automatically limited and reduced to the highest amount that is valid and enforceable as determined in such action or proceeding (such highest amount determined hereunder being the relevant Guarantor’s “Maximum Liability”). This Section 8.09 with respect to the Maximum Liability of the Guarantors is intended solely to preserve the rights of the Administrative Agent, Lenders and Lender Counterparties hereunder to the maximum extent not subject to avoidance under applicable law, and no Guarantor nor any other Person shall have any right or claim under this Section 8.09 with respect to the Maximum Liability, except to the extent necessary so that none of the obligations of any Guarantor hereunder shall not be rendered voidable under applicable law.

Section 8.10                             Keepwell.

(a)                                 Each Qualified ECP Guarantor hereby jointly and severally absolutely, unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each other Credit Party to honor all of its obligations under this Agreement in respect of Swap Obligations (provided, however, that each Qualified ECP Guarantor shall only be liable under this Section 8.10 for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section 8.10, or otherwise under this Agreement, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations of each Qualified ECP Guarantor under this Section 8.10 shall remain in full force and effect until this Agreement is terminated, all Obligations are paid in full (other than contingent obligations for which no claim has been made) and all of the Lenders’ Commitments are terminated.  Each Qualified ECP Guarantor intends that this Section 8.10 constitute, and this Section 8.10 shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of each other Credit Party for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.

(b)                                 Notwithstanding any other provisions of this Agreement or any other Loan Document, Obligations guaranteed by any Guarantor, or secured by the grant of any Lien by such Guarantor under any Security Document, shall exclude all Excluded Swap Obligations of such Guarantor.

61

ARTICLE X
The Administrative Agent

Each of the Lenders hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto.

64

The bank serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with any Credit Party or other Affiliate thereof as if it were not the Administrative Agent hereunder.

The Administrative Agent shall not have any duties or obligations except those expressly set forth herein.  Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing as directed by the Majority Lenders or Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 11.02), and (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to any Credit Party that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity.  The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Majority Lenders or the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 11.02) or in the absence of its own gross negligence or willful misconduct.  The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by a Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article V or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.  No Person identified as a Syndication Agent, Co-Documentation Agent or an Arranger, in each case, in its respective capacity as such, shall have any responsibilities or duties, or incur any liability, under this Agreement or the other Loan Documents.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person.  The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon.  The Administrative Agent may consult with legal counsel (who may be counsel for Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent.  The

65

Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties.  The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time upon notice to the Lenders and Borrower.  Upon any such resignation, the Majority Lenders shall have the right, with the consent of Borrower (which consent shall not be unreasonably withheld or delayed), to appoint a successor; provided that no consent of Borrower shall be required if any Default has occurred and is continuing.  If no successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent which shall be a bank with an office in New York, New York.  Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder.  The fees payable by Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between Borrower and such successor.  After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 11.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.  Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder.

Each Lender hereby authorizes the Administrative Agent to release any Collateral that is permitted to be sold or released pursuant to the terms of the Loan Documents.  Each Lender hereby authorizes the Administrative Agent to execute and deliver to Borrower, at Borrower’s sole cost and expense, any and all releases of Liens, termination statements, assignments or other documents reasonably requested by Borrower in connection with any sale or other disposition of Collateral to the extent such sale or other disposition is permitted by the terms of Section 7.05 of the Antero Resources Credit Agreement or is otherwise authorized by the terms of the Loan Documents. Each Lender hereby authorizes the Administrative Agent to subordinate Liens on any property or assets granted to or held by the Administrative Agent under any Loan Document to the holder of any Lien on such property or assets that constitutes a Permitted Lien of the type described in clause (h) of the definition thereof.

(b)                                 Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Credit Parties and the Majority Lenders or by the Credit Parties and the Administrative Agent with the consent of the Majority Lenders; provided that no such agreement shall (1) amend or waive any of the conditions specified in Article V without the written consent of each Lender (provided that the Administrative Agent may in its discretion withdraw any request it has made under Section 5.01(m)), (2) increase the Applicable Percentage of any Lender or increase the Commitment of any Lender without the written consent of such Lender, (3) increase the Maximum Facility Amount without the written consent of each Lender, (4) reduce the principal amount of any Loan or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (5) postpone the scheduled date of payment of the principal amount of any Loan, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of the Aggregate Commitment, without the written consent of each Lender affected thereby (it being understood that any waiver of a mandatory prepayment of the Loans or a mandatory reduction of the Commitments shall not constitute a postponement or waiver of a scheduled payment or date of expiration), (6) change Section 2.18(b) or Section 2.18(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (7) except in connection with any Dispositions permitted in Section 7.05 of the Antero Resources Credit Agreement, release any Credit Party from its obligations under the Loan Documents or release any of the Collateral without the written consent of each Lender, (8) change any of the provisions of this Section or the definition of “Majority Lenders” or “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender, or (9) amend this Section 11.02 without the consent of each Lender; provided further that no such agreement shall (x) amend, modify or otherwise affect the rights or duties of the Administrative Agent without the prior written consent of the Administrative Agent or (y) change any of the provisions of Section 2.22 without the prior written consent of the Administrative Agent.

(c)                                  Notwithstanding anything to the contrary contained in this Section 11.02, the Administrative Agent may, with the consent of Borrower only, amend, modify or supplement this Agreement or any of the other Loan Documents to correct any clerical errors or cure any ambiguity, omission, mistake, defect or inconsistency.

68

Section 11.03                      Expenses; Indemnity; Damage Waiver.

(a)                                 Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent, the Arrangers and their Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of this Agreement and the other Loan Documents or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), and (ii) all reasonable out-of-pocket expenses incurred by the Administrative Agent or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent or any Lender, in connection with the enforcement or protection of its rights in connection with the Loan Documents, including its rights under this Section, or in connection with the Loans made hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans.

(b)                                 THE CREDIT PARTIES SHALL INDEMNIFY THE ADMINISTRATIVE AGENT AND EACH LENDER, AND EACH RELATED PARTY OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON BEING CALLED AN “INDEMNITEE”) AGAINST, AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, PENALTIES, LIABILITIES AND RELATED EXPENSES, INCLUDING THE FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF (I) THE EXECUTION OR DELIVERY OF THIS AGREEMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY, THE PERFORMANCE BY THE PARTIES HERETO OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THE CONSUMMATION OF THE TRANSACTIONS OR ANY OTHER TRANSACTIONS CONTEMPLATED HEREBY, (II) ANY LOAN OR THE USE OF THE PROCEEDS THEREFROM, (III) ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY BORROWER OR ANY SUBSIDIARY, OR ANY ENVIRONMENTAL LIABILITY RELATED IN ANY WAY TO BORROWER OR ANY SUBSIDIARY, OR (IV) ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO.  THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR RELATED EXPENSES ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY OR CAUSED, IN WHOLE OR IN PART BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY INDEMNITEE; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES

69

OR RELATED EXPENSES ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE.  FOR THE AVOIDANCE OF DOUBT, WITH RESPECT TO THE FOREGOING PROVISO “ANY INDEMNITEE” MEANS ONLY THE INDEMNITEE OR INDEMNITEES, AS THE CASE MAY BE, THAT ARE DETERMINED BY SUCH COURT TO HAVE BEEN GROSSLY NEGLIGENT OR TO HAVE ENGAGED IN WILLFUL MISCONDUCT AND NOT ANY OTHER INDEMNITEE.

(c)                                  To the extent that any Credit Party fails to pay any amount required to be paid by it to the Administrative Agent under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent such Lender’s Applicable Percentage of such unpaid amount with respect to amounts to be paid to the Administrative Agent (in each case, determined as of the time that the applicable unreimbursed expense or indemnity payment is sought); provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such.

(d)                                 TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE CREDIT PARTIES SHALL NOT ASSERT, AND HEREBY WAIVE, ANY CLAIM AGAINST ANY INDEMNITEE, ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES (AS OPPOSED TO DIRECT OR ACTUAL DAMAGES) ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF, THIS AGREEMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY, THE TRANSACTIONS, ANY LOAN OR THE USE OF THE PROCEEDS THEREOF.

(e)                                  All amounts due under this Section shall be payable not later than ten (10) days after written demand therefor.

Section 11.04                      Successors and Assigns.

(a)                                 The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that (i) no Credit Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by such Credit Party without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section.  Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

70

(b)                                 (i)  Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of:

(A)                               Borrower; provided that no consent of Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, a Federal Reserve Bank, an Approved Fund or, if any Event of Default has occurred and is continuing, any other assignee; and

(B)                               the Administrative Agent.

(ii)                                  Assignments shall be subject to the following additional conditions:

(A)                               except in the case of an assignment to a Lender, an Affiliate of a Lender, an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of Borrower and the Administrative Agent otherwise consent; provided that no such consent of Borrower shall be required if any Event of Default has occurred and is continuing;

(B)                               each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of such Lender’s Commitment and such Lender’s Loans under this Agreement;

(C)                               the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; provided that no such processing and recordation fee shall be required for an assignment by a Lender to an Affiliate of such Lender;

(D)                               the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire; and;

(E)                                notwithstanding anything to the contrary herein, after giving effect to any such Assignment, the Applicable Percentage of any assigning Lender and any assignee Lender shall be equal to the “Applicable Percentage” of such assigning Lender and such assignee Lender, respectively, under and as defined in the Antero Resources Credit Agreement and in the event any Lender is required to assign any or all of its rights and obligations under this Agreement, such Lender shall also be

71

required to assign its rights and obligations under the Antero Resources Credit Agreement in the corresponding Applicable Percentage.

For the purposes of this Section 11.04(b), the term “Approved Fund” has the following meaning:

“Approved Fund” means any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender.

(iii)                               Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 2.15, Section 2.16, Section 2.17 and Section 11.03).  Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 11.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section except that any attempted assignment or transfer by any Lender that does not comply with clause (C) of Section 11.04(b)(ii) shall be null and void.

(iv)                              The Administrative Agent, acting for this purpose as an agent of Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment and Applicable Percentage of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”).  The entries in the Register shall be conclusive, and the Credit Parties, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary.  The Register shall be available for inspection by the Credit Parties and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v)                                 Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section, and any written consent to such assignment required by paragraph (b) of

72

this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to Section 2.07, Section 2.18(d) or Section 11.03(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon.  No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c)                                  (i)  Any Lender may, without the consent of Borrower, the Administrative Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement.  Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 11.02(b) that affects such Participant.  Subject to paragraph (c)(ii) of this Section, Borrower agree that each Participant shall be entitled to the benefits of Section 2.15, Section 2.16 and Section 2.17 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section.  To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.18(c) as though it were a Lender. Notwithstanding anything to the contrary herein, after giving effect to any such participation, the Applicable Percentage of any selling Lender and any Participant shall be equal to the “Applicable Percentage” of such selling Lender and such Participant, respectively, under and as defined in the Antero Resources Credit Agreement and in the event any Participant is required to assign or sell any or all of its rights and obligations under this Agreement, such Participant shall also be required to assign or sell its rights and obligations under the Antero Resources Credit Agreement in the corresponding Applicable Percentage.

(ii)                                  A Participant shall not be entitled to receive any greater payment under Section 2.15 or Section 2.17 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the prior written consent of Borrower.  A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.17 unless Borrower is notified of the participation sold to such Participant and such Participant agrees,

73

for the benefit of Borrower, to comply with Section 2.17(e) as though it were a Lender.

(d)                                 Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Section 11.05                      Survival.  All covenants, agreements, representations and warranties made by the Credit Parties herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid and so long as the Aggregate Commitment has not expired or terminated.  The provisions of Section 2.15, Section 2.16, Section 2.17, Section 11.03, Section 11.12 and Article X shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans the Aggregate Commitment or the termination of this Agreement or any provision hereof.

Section 11.06                      Counterparts; Integration; Effectiveness.  This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract.  This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.  Except as provided in Section 5.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns.  Delivery of an executed counterpart of a signature page of this Agreement by telecopy or other electronic means shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 11.07                      Severability.  Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of

74

such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Section 11.08                      Right of Setoff.  If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of Borrower against any of and all the obligations of any Credit Party now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured.  The rights of each Lender under this Section and Section 8.07 are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

Section 11.09                      GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS.

(a)                                 THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES THEREOF.

(b)                                 EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR NEW YORK STATE COURT SITTING IN THE BOROUGH OF MANHATTAN, CITY OF NEW YORK, NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE OR, TO THE EXTENT PERMITTED BY LAW, IN SUCH FEDERAL COURT.  EACH OF THE PARTIES HERETO AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW.  NOTHING IN THIS AGREEMENT SHALL AFFECT ANY RIGHT THAT THE ADMINISTRATIVE AGENT OR ANY LENDER MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT AGAINST ANY CREDIT PARTY OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

(c)                                  EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT IT MAY LEGALLY AND EFFECTIVELY DO SO, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT IN ANY

75

COURT REFERRED TO IN PARAGRAPH (B) OF THIS SECTION.  EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

(d)                                 EACH PARTY TO THIS AGREEMENT IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 11.01.  NOTHING IN THIS AGREEMENT WILL AFFECT THE RIGHT OF ANY PARTY TO THIS AGREEMENT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW.

Section 11.10                      WAIVER OF JURY TRIAL.  EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY).  EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 11.14                      USA PATRIOT Act.  Each Lender that is subject to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”) hereby notifies each Credit Party that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies each Credit Party, which information includes the name and address of each Credit Party and other information that will allow such Lender to identify each Credit Party in accordance with the Act.  Borrower shall, upon the request of the Administrative Agent or any Lender, provide all documentation and other information that the Administrative Agent or such Lender reasonably requires to comply with its ongoing obligations under applicable “know your customer” and anti-money laundering rules and regulations, including the Act.
