“Acquired Debt” means, with respect to any specified Person:

(1) Indebtedness of any other Person existing at the time such other Person is merged with or into or became a Subsidiary of such specified Person, whether or not such Indebtedness is incurred in connection with, or in contemplation of, such other Person merging with or into, or becoming a Restricted Subsidiary of, such specified Person, but excluding Indebtedness which is extinguished, retired or repaid in connection with such Person merging with or becoming a Subsidiary of such specific Person; and

(2) the issuance of Equity Interests in any of Antero Midstream Partners’ Restricted Subsidiaries or the sale of Equity Interests in any of its Restricted Subsidiaries.

Notwithstanding the preceding, none of the following items will be deemed to be an Asset Sale:

(9) the creation or perfection of a Lien that is not prohibited by Section 4.12 hereof;

“Attributable Debt” in respect of a sale-and-leaseback transaction means, at the time of determination, the present value of the obligation of the lessee for net rental payments during the remaining term of the lease included in such sale-and-leaseback transaction including any period for which such lease has been extended or may, at the option of the lessor, be extended. As used in the preceding sentence, “net rental payments” under any lease for any such period shall mean the sum of rental and other payments required to be paid with respect to such period by the lessee thereunder, excluding any amounts required to be paid by such lessee on account of maintenance and repairs, insurance, taxes, assessments, water rates or similar charges. In the case of any lease that is terminable by the lessee upon payment of penalty, such net rental payment shall also include the amount of such penalty, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated. For purposes of this definition, present value shall be calculated using a discount rate equal to the rate of interest implicit in the subject transaction, determined in accordance with GAAP; provided, however, that if such sale-and-leaseback transaction results in a Capital Lease Obligation, the amount of Indebtedness represented thereby will be determined in accordance with the definition of “Capital Lease Obligation.”

“Bankruptcy Law” means Title 11, U.S. Code or any similar federal or state law for the relief of debtors.

“Beneficial Owner” has the meaning assigned to such term in Rule 13d-3 and Rule 13d-5 under the Exchange Act, except that in calculating the beneficial ownership of any particular “person” (as that term is used in Section 13(d)(3) of the Exchange Act), such “person” will be deemed to have beneficial ownership of all securities that such “person” has the right to acquire by conversion or exercise of other securities, whether such right is currently exercisable or is exercisable only after the passage of time. The terms “Beneficially Owns” and “Beneficially Owned” have a corresponding meaning. For purposes of this definition, a Person shall be deemed not to Beneficially Own securities that are the subject of a stock or unit purchase agreement, merger agreement or similar agreement until consummation of the transactions or, as applicable, series of related transactions contemplated thereby.

“Board of Directors” means:

(1) with respect to a corporation, the board of directors of the corporation or any committee thereof duly authorized to act on behalf of such board;

“Business Day” means any day other than a Legal Holiday.

“Capital Lease Obligation” means an obligation that is required to be classified and accounted for as a capital lease for financial reporting purposes in accordance with GAAP, and the amount of Indebtedness represented by such obligation shall be, at the time any determination thereof is to be made, the amount of the liability in respect of a capital lease that would at such time be required to be capitalized on a balance sheet in accordance with GAAP, and the Stated Maturity thereof shall be the date of the last payment of rent or any other amount due under such lease prior to the first date upon which such lease may be prepaid by the lessee without payment of a penalty.

“Capital Stock” means:

(1) in the case of a corporation, corporate stock;

(2) in the case of an association or business entity, any and all shares, interests, participations, rights or other equivalents (however designated) of corporate stock;

(4) any other interest or participation that confers on a Person the right to receive a share of the profits and losses of, or distributions of assets of, the issuing Person, but excluding from all of the foregoing any debt securities convertible into Capital Stock, whether or not such debt securities include any right of participation with Capital Stock.

“Cash Equivalents” means:

(1) securities issued or fully guaranteed or insured by the United States government or any agency thereof having maturities of not more than twenty-four (24) months from the date of acquisition thereof;

(2) time deposits with, certificates of deposit, bankers’ acceptances or Eurodollar time deposits of, any commercial bank that is a lender under the Credit Agreement or (a) is organized under the laws of the United States of America, any state thereof or the District of Columbia or is the principal banking subsidiary of a bank holding company organized under the laws of the United States of America, any state thereof or the District of Columbia or any United States branch of a foreign bank, and is a member of the Federal Reserve System, (b) issues long term securities with a rating of at least A- (or then equivalent grade, in each case with a stable outlook) by S&P and A3

(4) taxable and tax-exempt municipal securities rated at least A- (or then equivalent grade) by S&P and A3 (or then equivalent grade) by Moody’s, including variable rate municipal securities, having maturities or put rights of not more than twenty-four (24) months from the date of acquisition;

(5) corporate or bank debt of an issuer rated at least A- (or then equivalent grade, in each case with a stable outlook) by S&P and A3 (or then equivalent grade, in each case with stable outlook) by Moody’s at the time of acquisition and having maturities of not more than twenty-four (24) months from the date of acquisition;

(6) repurchase agreements relating to any of the investments listed in clauses (1) through (5) above with a market value at least equal to the consideration paid in connection therewith, with any Person who regularly engages in the business of entering into repurchase agreements and has a combined capital and surplus of not less than $500,000,000 whose long term securities are rated at least A- (or then equivalent grade) by S&P and A3 (or then equivalent grade) by Moody’s at the time of acquisition;

(7) asset-backed securities having as the underlying asset securities issued or guaranteed by the Federal Home Loan Mortgage Corporation or the Federal National Mortgage Association rated at least A- (or then equivalent grade, in each case with stable outlook) by S&P and A3 (or then equivalent grade, in each case with case with stable outlook) by Moody’s at the time of acquisition and having maturities of not more than twenty-four (24) months from the date of acquisition; and

(8) Investments, classified in accordance with GAAP as current assets of Antero Midstream Partners or any of its Subsidiaries, in money market mutual or similar funds having assets in excess of $100,000,000, at least 95% of the assets of which are comprised of assets specified in clauses (1) through (7) above of this definition.

“Change of Control” means the occurrence of any of the following:

(1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of Antero Midstream Partners and its Subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d) of the Exchange Act), which occurrence is followed by a Rating Decline;

(2) the adoption of a plan relating to the liquidation or dissolution of Antero Midstream Partners or the removal of the General Partner by the limited partners of Antero Midstream Partners; or

Notwithstanding the preceding, (a) a conversion of Antero Midstream Partners from a limited partnership to a corporation, limited liability company or other form of entity or an exchange of all of the outstanding limited partnership interests for capital stock in a corporation, for member interests in a limited liability company or for Equity Interests in such other form of entity shall not constitute a Change of Control, so long as following such conversion or exchange the “persons” (as defined above) who Beneficially Owned the Capital Stock of Antero Midstream Partners immediately prior to such transactions continue to Beneficially Own in the aggregate more than 50% of the Voting Stock of such entity, or continue to Beneficially Own sufficient Equity Interests in such entity to elect a majority of its directors, managers, trustees or other persons serving in a similar capacity for such entity and (b) a “person” or “group” shall not be deemed to Beneficially Own securities subject to a stock or asset purchase agreement, merger agreement or similar agreement (or voting or option or similar agreement related thereto) until the consummation of the transactions contemplated by such agreement.

For the avoidance of doubt, the completion of the transactions contemplated by the Simplification Agreement, dated October 9, 2018, among Antero Midstream Partners, Antero Midstream GP LP and the other parties thereto will not constitute a Change of Control.

(3) the cumulative effect of a change in accounting principles will be excluded;

(a) General. The Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of its authentication. The Notes shall be in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The terms and provisions contained in the Notes will constitute, and are hereby expressly made, a part of this Indenture and the Issuers, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

(b) Global Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, repurchases and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

Section 2.02 Execution and Authentication.

At least one Officer must sign the Notes for each of the Issuers by manual or facsimile signature.

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid.

A Note will not be valid until authenticated by the manual signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee will, upon receipt of a written order of the Issuers signed by an Officer of each Issuer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Issuers pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.

The Trustee may appoint an authenticating agent acceptable to the Issuers to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Issuers.

Section 2.03 Registrar and Paying Agent.

The Issuers will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Issuers may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuers may change any Paying Agent or Registrar without notice to any Holder. The Issuers will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuers fail to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. Antero Midstream Partners, Finance Corp. or any of Antero Midstream Partners’ other Subsidiaries may act as Paying Agent or Registrar.

The Issuers initially appoint The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes.

The Issuers will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and will notify the Trustee of any default by the Issuers in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuers at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than Antero Midstream Partners or a Subsidiary) will have no further liability for the money. If Antero Midstream Partners or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or

reorganization proceedings relating to Antero Midstream Partners, the Trustee will serve as Paying Agent for the Notes.

Section 2.05 Holder Lists.

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA §312(a). If the Trustee is not the Registrar, the Issuers will furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes, and the Issuers shall otherwise comply with TIA §312(a).

(h) General Provisions Relating to Transfers and Exchanges.

(2) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Issuers may require payment of a sum sufficient to cover any transfer or exchange tax or similar governmental charge payable in connection therewith (other than any such transfer or exchange taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.04 hereof).

(3) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Issuers, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

(4) Neither the Registrar nor the Issuers will be required:

(A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection;

Section 2.07 Replacement Notes.

If any mutilated Note is surrendered to the Trustee or the Issuers and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuers will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuers, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuers to protect the Issuers, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuers may charge for their expenses in replacing a Note.

Every replacement Note is an additional obligation of each of the Issuers and will be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

Section 2.08 Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Issuers or an Affiliate of the Issuers holds the Note; however, Notes held by Antero Midstream Partners or a Subsidiary of Antero Midstream Partners shall not be deemed to be outstanding for purposes of Section 3.07(a) hereof.

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than Antero Midstream Partners, a Subsidiary or an Affiliate of any thereof) holds, by 11:00 a.m., Eastern Time, on a Redemption Date or other maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

Section 2.09 Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuers or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuers or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded.

Section 2.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuers consider appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuers will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes.

Holders of temporary Notes will be entitled to all of the benefits of this Indenture.

Section 2.11 Cancellation.

The Issuers at any time may deliver Notes to the Trustee for cancellation.

The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes will be delivered to the Issuers upon request. The Issuers may not issue new Notes to replace Notes that they have paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

If the Issuers default in a payment of interest on the Notes, they will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuers will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuers will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the Issuers) will send or cause to be sent to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

Section 2.13 Trustee, Paying Agent, Registrar Not Responsible for Depositary

None of the Trustee, any Paying Agent or the Registrar shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in any Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. The Trustee, any Paying Agent and the Registrar shall be entitled to deal with any Depositary, and any nominee thereof, that is the Holder of any Global Note for all purposes of this Indenture relating to such Global Note (including the payment of principal, premium, if any, and interest, the giving of instructions or directions by or to the owner or holder of a beneficial ownership interest in such Global Note) as the sole Holder of such Global Note and shall have no obligations to the beneficial owners thereof. None of the Trustee, any Paying Agent or the Registrar shall have any responsibility or liability for any acts or omissions of any Depositary with respect to any Global Notes, for the records of any Depositary, including records in respect of beneficial ownership interests in respect of any Global Note, for any transactions between such Depositary and any participant in such Depositary or between or among any such Depositary, any such participant or any holder or owner of a beneficial interest in any Global Note or for any transfers of beneficial interests in any Global Note.

Notice of any redemption of the Notes (including upon an Equity Offering or in connection with a transaction (or series of related transactions) that constitute a Change of Control) may, at the Issuers’ discretion, be given prior to the completion thereof and be subject to one or more conditions precedent, including, but not limited to, completion of the related Equity Offering or Change of Control. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuers’ discretion, the Redemption Date may be delayed until such time (including more than 60 days after the date the notice of redemption was delivered) as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date so delayed, or such notice may be rescinded at any time in the Issuers’ discretion if in the good faith judgment of the Issuers any or all of such conditions will not be satisfied.

(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(6) that, unless the Issuers default in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the Redemption Date;

(7) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed;

(8) any condition precedent to the redemption; and

(9) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.

At the Issuers’ request, the Trustee will give the notice of redemption in the Issuers’ names and at their expense; provided, however, that the Issuers have delivered to the Trustee written notice in accordance with Section 3.01 requesting that the Trustee give such notice and a form of the notice of redemption setting forth the information specified in the preceding paragraph.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is given in accordance with Section 3.03 hereof, Notes called for redemption without condition will become irrevocably due and payable on the Redemption Date at the redemption price.

Section 3.05 Deposit of Redemption or Purchase Price.

Prior to 11:00 a.m., Eastern Time, on the redemption or purchase date, the Issuers will deposit with the Trustee or with the Paying Agent money sufficient (as determined by the Issuers) to pay the redemption or purchase price of and accrued interest on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest on all Notes to be redeemed or purchased.

If the Issuers comply with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or accepted for purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or tendered for purchase is not so paid upon surrender for redemption or purchase because of the failure of the Issuers to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate then in effect as provided in the Notes and in Section 4.01 hereof.

Section 3.06 Notes Redeemed or Purchased in Part.

Upon surrender of a Note that is redeemed or purchased in part, the Issuers will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Issuers a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

Section 3.07 Optional Redemption.

(a) At any time prior to March 1, 2022, the Issuers may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes (including any Additional Notes) issued under this Indenture, upon prior notice in accordance with Section 3.02 hereof, at a redemption price of 105.750% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date (subject to the right of Holders of Notes on the relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date), with an amount of cash not greater than the net cash proceeds of one or more Equity Offerings by Antero Midstream Partners; provided that:

(1) at least 65% of the aggregate principal amount of Notes (including any Additional Notes) issued under this Indenture (excluding Notes held by Antero Midstream Partners and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and

(2) the redemption occurs within 180 days of the date of the closing of such Equity Offering.

(b) Except pursuant to the preceding paragraph, subsection (d) of this Section 3.07, and Section 4.15(d) hereof, the Notes will not be redeemable at the Issuers’ option prior to March 1, 2022.

(c) On or after March 1, 2022, the Issuers may redeem all or a part of the Notes, upon prior notice in accordance with Section 3.02 hereof, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if any, on the Notes redeemed to, but excluding, the applicable Redemption Date, if redeemed during the twelve-month period beginning on March 1 of each year indicated below, subject to the rights of Holders of Notes on the relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date:

Year	Percentage
2022	102.875	%
2023	101.917	%
2024	100.958	%
2025 and thereafter	100.000	%

(d) At any time prior to March 1, 2022, the Issuers may also redeem all or a part of the Notes, upon prior notice in accordance with Section 3.02 hereof, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but excluding, the Redemption Date, subject to the rights of Holders on the relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date. The notice need not set forth the Applicable Premium but only the manner of calculation of the redemption price. With respect to any redemption pursuant to this Section 3.07(d), Antero Midstream Partners will (i) calculate the Treasury Rate on the second Business Day preceding the applicable Redemption Date and (ii) prior to such Redemption Date file with the Trustee an Officers’ Certificate setting forth the Applicable Premium and the Treasury Rate and showing the calculation of each in reasonable detail. The Trustee shall not be responsible for any such calculation.

(e) Any redemption pursuant to this Section 3.07 or Section 4.15(d) shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

(f) Unless the Issuers default in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable Redemption Date.

Section 3.08 Mandatory Redemption.

The Issuers are not required to make mandatory redemption or sinking fund payments with respect to the Notes. The Issuers are not prohibited from acquiring the Notes by means other than a redemption, whether pursuant to a tender offer, open market purchase or otherwise, so long as the acquisition does not violate the terms of this Indenture.

Section 3.09 Offer to Purchase by Application of Excess Proceeds.

In the event that, pursuant to Section 4.10 hereof, the Issuers are required to commence an offer to all Holders to purchase Notes (an “Asset Sale Offer”), it will follow the procedures specified below.

The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Issuers will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other

Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made.

If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.

Upon the commencement of an Asset Sale Offer, the Issuers will send, in the manner prescribed in Section 12.02, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

(1) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer will remain open;

(2) the Offer Amount, the purchase price and the Purchase Date;

(3) that any Note not tendered or accepted for payment will continue to accrue interest;

(4) that, unless the Issuers default in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date;

(5) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in integral multiples of $1,000 only;

(6) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Issuers, a Depositary, if appointed by the Issuers, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date;

(7) that Holders will be entitled to withdraw their election if the Issuers, the depositary for the Asset Sale Offer or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

(8) that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the Offer Amount, the Notes and other pari passu Indebtedness to be purchased will be selected on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Issuers so that only Notes in denominations of $2,000, or integral multiples of $1,000 in excess thereof, will be purchased); and

(9) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer).

On or before the Purchase Date, the Issuers will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver

or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Issuers in accordance with the terms of this Section 3.09. The Issuers, the depositary for the Asset Sale Offer or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Issuers for purchase, and the Issuers will promptly issue a new Note, and the Trustee, upon written request from the Issuers, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Issuers to the Holder thereof. The Issuers will publicly announce the results of the Asset Sale Offer on the Purchase Date.

Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.05 and 3.06 hereof.

ARTICLE 4
COVENANTS

Section 4.01 Payment of Notes.

The Issuers will pay or cause to be paid the principal of, premium, if any, and interest on the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest will be considered paid on the date due if the Paying Agent, if other than the Antero Midstream Partners or a Subsidiary thereof, holds as of 11:00 a.m. Eastern Time on the due date money deposited by the Issuers in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due. With respect to physical certificates, presentation is due at maturity.

The Issuers shall pay interest on overdue principal, and they shall pay interest on overdue installments of interest, at the rate then prevailing on the Notes to the extent lawful.

Notwithstanding anything to the contrary contained in this Indenture, the Issuers may, to the extent required to do so by law, deduct or withhold income or other similar taxes imposed by the United States of America from principal or interest payments hereunder.

Section 4.02 Maintenance of Office or Agency.

The Issuers will maintain in the City of New York an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuers in respect of the Notes and this Indenture may be served. The Issuers will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuers fail to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

The Issuers may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission will in any manner relieve the Issuers of their obligation to maintain an office or agency in the City of New York for such purposes. The Issuers will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Issuers hereby designate the Corporate Trust Office of the Trustee as one such office or agency of the Issuers in accordance with Section 2.03 hereof.

Section 4.03 Reports.

(a) Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, Antero Midstream Partners shall furnish (whether through hard copy or internet access) to the Holders of Notes and the Trustee, within the time periods specified in the SEC’s rules and regulations:

(1) all quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if Antero Midstream Partners were required to file such reports; and

(2) all current reports that would be required to be filed with the SEC on Form 8-K if Antero Midstream Partners were required to file such reports.

All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports; provided, however, that if at any time Antero Midstream Partners is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, it may complete any of the reports referred to in clauses (1) and (2) of this Section 4.03(a) as though its only registered securities were the Notes. Each annual report on Form 10-K will include a report on Antero Midstream Partners’ consolidated financial statements by Antero Midstream Partners’ independent registered public accounting firm. So long as Antero Midstream Partners is a consolidated Subsidiary of AMC (or another parent company) for financial reporting purposes, Antero Midstream Partners may satisfy its obligations under this Section 4.03 with respect to the information specified in clauses (1) and (2) of this Section 4.03(a) by furnishing the corresponding reports of AMC (or such other parent company), within the time periods specified in the SEC’s rules and regulations for filing such corresponding reports; provided, however, that AMC (or such other parent company) has fully and unconditionally guaranteed the Notes pursuant to a supplemental indenture. The availability of the reports of Antero Midstream Partners specified in clauses (1) and (2) above or, to the extent set forth in this Section 4.03(a), the corresponding reports of AMC (or such other parent company), on the SEC’s EDGAR filing system (or any successor filing system) or a publicly available website of Antero Midstream Partners or AMC (or such other parent company) will be deemed to satisfy the foregoing delivery requirements.

The Trustee shall have no obligation to determine if and when the reports, information and documents of Antero Midstream Partners are filed with the SEC via the EDGAR system and available on the SEC’s EDGAR website.

Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including Antero Midstream Partners’ compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely conclusively on Officers’ Certificates). The Trustee is under no duty to examine such reports, information or documents to ensure compliance with the provisions of this Indenture or to ascertain the correctness or otherwise of the information or the statements contained therein.

Any and all Defaults or Events of Default arising from a failure to comply with this Section 4.03 shall be deemed cured (and Antero Midstream Partners shall be deemed to be in compliance with this Section 4.03) upon furnishing or filing such information or report as contemplated by this covenant (but without regard to the date on which such information or report is so furnished or filed); provided that such cure shall not otherwise affect the rights of Holders under Section 6.01 hereof if all outstanding Notes shall

have been accelerated in accordance with the terms of this Indenture and such acceleration has not been rescinded or cancelled prior to such cure.

(b) For so long as any Notes remain outstanding, if at any time none of Antero Midstream Partners and the Guarantors is required to file with the SEC the reports required by paragraph (a) of this Section 4.03, Antero Midstream Partners and the Guarantors will furnish to the Holders of Notes and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(b) So long as any of the Notes are outstanding, the Issuers and the Guarantors will deliver to the Trustee, promptly upon any Officer thereof becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Issuers are taking or propose to take with respect thereto.

Section 4.05 Taxes.

Antero Midstream Partners will pay, and will cause each of its Restricted Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

Section 4.06 Stay, Extension and Usury Laws.

The Issuers and each of the Guarantors covenant (to the extent that they may lawfully do so) that they will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Issuers and each of the Guarantors (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and covenants that they will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

Section 4.07 Restricted Payments.

(11) other Restricted Payments in an aggregate amount not to exceed $25.0 million since the Issue Date.

The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by Antero Midstream Partners or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment, except that the amount of any non-cash dividend or distribution paid in accordance with clause (1) of Section 4.07(b) hereof shall be the Fair Market Value as of the date on which such dividend or distribution is declared. The Fair Market Value of any assets or securities that are required to be valued by this Section 4.07 will be determined in the manner prescribed in the definition of that term. For the purposes of determining compliance with this Section 4.07, in the event that a (a) Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in the preceding clauses (1) through (11), Antero Midstream Partners will be permitted to classify (or reclassify in whole or in part in its sole discretion) such Restricted Payment in any manner that complies with this Section 4.07 and (b) a Restricted Payment is made pursuant to clause (1) or (2) of Section 4.07(a), Antero Midstream Partners will be permitted to classify whether all or any portion thereof is being (and in the absence of such classification shall be deemed to have classified the minimum amount possible as having been) made with Incremental Funds.

(1) pay dividends or make any other distributions on its Equity Interests to Antero Midstream Partners or any of its Restricted Subsidiaries, or pay any indebtedness owed to Antero Midstream Partners or any of its Restricted Subsidiaries; provided that priority of any preferred equity or similar Equity Interest in receiving dividends or liquidating distributions prior to the payment of dividends or liquidating distributions on common equity shall not be deemed to be a restriction on the ability to make distributions on Equity Interests;

(2) make loans or advances to Antero Midstream Partners or any of its other Restricted Subsidiaries; or

(3) sell, lease or otherwise transfer any of its properties or assets to Antero Midstream Partners or any of its other Restricted Subsidiaries.

(1) agreements as in effect on the Issue Date and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements or the Indebtedness to which they relate; provided that the amendments, restatements,

modifications, renewals, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend, distribution and other payment restrictions than those contained in those agreements on the Issue Date;

(2) this Indenture, the Notes and the Note Guarantees;

(3) agreements governing other Indebtedness permitted to be incurred under the provisions of the covenant described above under Section 4.09 and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of such agreements; provided that the restrictions therein are not materially more restrictive, taken as a whole, than those contained in this Indenture, the Notes and the Note Guarantees;

(4) applicable law, rule, regulation or order;

(5) any instrument governing Indebtedness or Equity Interest of a Person acquired by Antero Midstream Partners or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Equity Interest was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

(6) customary non-assignment provisions in transportation agreements or purchase and sale or exchange agreements, pipeline and water treatment agreements, or similar operational agreements or in licenses or leases, in each case entered into in the ordinary course of business;

(7) purchase money obligations for property acquired in the ordinary course of business and Capital Lease Obligations that impose restrictions on the property purchased or leased of the nature described in clause (3) of Section 4.08(a) hereof;

(8) any agreement (a) for the sale or other disposition of a Restricted Subsidiary that contains any such restrictions on that Restricted Subsidiary pending its sale or other disposition or (b) for the sale or other disposition of a particular asset or line of business of a Restricted Subsidiary that imposes restrictions on assets subject to any agreement of the nature described in clause (3) of Section 4.08(a) hereof;

(9) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;

(10) Liens permitted to be incurred under the provisions of Section 4.12 hereof that limit the right of the debtor to dispose of the assets subject to such Liens;

(11) provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements entered into in the ordinary course of business;

(12) any agreement or instrument relating to any property or assets acquired after the Issue Date, so long as such encumbrance or restriction relates only to the property or assets so acquired and is not and was not created in anticipation of such acquisitions;

(13) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;

(14) any instrument governing Indebtedness of a FERC Subsidiary, provided that such Indebtedness was otherwise permitted to be incurred under this Indenture; and

(15) encumbrances or restrictions contained in, or in respect of, Hedging Obligations permitted under this Indenture from time to time.

Section 4.09 Incurrence of Indebtedness and Issuance of Disqualified Equity.

(a) Antero Midstream Partners will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, Guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and Antero Midstream Partners will not issue any Disqualified Equity and will not permit any of its Restricted Subsidiaries to issue any Disqualified Equity; provided, however, that Antero Midstream Partners and any Restricted Subsidiary may incur Indebtedness (including Acquired Debt) and Antero Midstream Partners and the Restricted Subsidiaries may issue Disqualified Equity, if the Fixed Charge Coverage Ratio for the Antero Midstream Partners’ Reference Period immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Equity is issued, as the case may be, would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Equity had been issued, as the case may be, at the beginning of such Reference Period.

(b) The provisions of Section 4.09(a) hereof will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”) or the issuance of any Disqualified Equity described in clause (11) below:

(1) the incurrence by Antero Midstream Partners or any of its Restricted Subsidiaries of additional Indebtedness and letters of credit and the Guarantees thereof under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of Antero Midstream Partners and its Restricted Subsidiaries thereunder) not to exceed the greater of (a) $2.0 billion and (b) the sum of $1.4 billion and 30% of Consolidated Net Tangible Assets (determined as of the date of incurrence and after giving effect to the use of proceeds therefrom);

(2) the incurrence by Antero Midstream Partners and its Restricted Subsidiaries of any Existing Indebtedness;

(3) the incurrence by the Issuers and the Guarantors of Indebtedness represented by the Notes and the related Note Guarantees issued on the Issue Date;

(4) the incurrence by Antero Midstream Partners or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of Antero Midstream Partners or any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), at any time outstanding

not to exceed the greater of (a) $100.0 million and (b) 5.0% of Consolidated Net Tangible Assets (determined as of the date of incurrence and after giving effect to the use of proceeds therefrom);

(5) the incurrence by Antero Midstream Partners or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under Section 4.09(a) hereof or clause (2), (3), (4) or (10) of this Section 4.09(b) or this clause (5);

(6) the incurrence by Antero Midstream Partners or any of its Restricted Subsidiaries of intercompany Indebtedness between or among Antero Midstream Partners and any of its Restricted Subsidiaries; provided, however, that:

(A) if Antero Midstream Partners or any Guarantor is the obligor on such Indebtedness and the payee is not Antero Midstream Partners or a Guarantor, such Indebtedness must be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of Antero Midstream Partners, or the Note Guarantee, in the case of a Guarantor; and

(B) (1) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than Antero Midstream Partners or a Restricted Subsidiary of Antero Midstream Partners and (2) any sale or other transfer of any such Indebtedness to a Person that is not either Antero Midstream Partners or a Restricted Subsidiary of Antero Midstream Partners,

will be deemed, in each case, to constitute an incurrence of such Indebtedness by Antero Midstream Partners or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

(7) the incurrence by Antero Midstream Partners or any of its Restricted Subsidiaries of Hedging Obligations or Indebtedness under Treasury Management Arrangements;

(8) the Guarantee by Antero Midstream Partners, or any of its Restricted Subsidiaries of (a) Indebtedness of Antero Midstream Partners or a Restricted Subsidiary of Antero Midstream Partners that was permitted to be incurred by another provision of this Section 4.09 or (b) Indebtedness incurred by Joint Ventures, provided that such Guarantee constitutes a Permitted Investment; and provided further, in each case, that if the Indebtedness being Guaranteed is subordinated to or pari passu with the Notes or the Note Guarantees, then the Guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness Guaranteed;

(9) the incurrence by Antero Midstream Partners or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims, health or other types of social security benefits, unemployment or other insurance or self-insurance obligations, insurance contracts, reclamation, statutory obligations, bankers’ acceptances, and performance, payment, appeal and surety bonds in the ordinary course of business, including Guarantees and obligations respecting standby letters of credit supporting such obligations, to the extent not drawn (in each case other than an obligation for money borrowed) and replacements of any of the foregoing;

(10) the incurrence by Antero Midstream Partners or any of its Restricted Subsidiaries of Permitted Acquisition Indebtedness;

(11) the issuance by Antero Midstream Partners or any of its Restricted Subsidiaries of Disqualified Equity to Antero Midstream Partners or any of its Restricted Subsidiaries, as the case may be; provided, however, that:

(A) any subsequent issuance or transfer of Equity Interests of a Restricted Subsidiary that results in any such Disqualified Equity being held, directly or indirectly, by a Person other than Antero Midstream Partners or a Restricted Subsidiary of Antero Midstream Partners; and

(B) any sale or other transfer of any such Disqualified Equity to a Person that is not either Antero Midstream Partners or a Restricted Subsidiary of Antero Midstream Partners;

will be deemed, in each case, to constitute an issuance of such Disqualified Equity by Antero Midstream Partners or such Restricted Subsidiary that was not permitted by this clause;

(12) the incurrence in the ordinary course of business by Antero Midstream Partners or any of its Restricted Subsidiaries of Indebtedness under letters of credit incurred pursuant to a Credit Facility, provided that such obligations are reimbursed within 10 days following the drawing of such letter of credit;

(13) the incurrence by Antero Midstream Partners or any of its Restricted Subsidiaries of liability in respect of the Indebtedness of any Unrestricted Subsidiary of Antero Midstream Partners or any Joint Venture but only to the extent that such liability is the result of Antero Midstream Partners’ or any such Restricted Subsidiary’s being a general partner of such Unrestricted Subsidiary or Joint Venture and not as guarantor of such Indebtedness and provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this clause (13) and then outstanding does not exceed $25.0 million; and

(14) the incurrence by Antero Midstream Partners or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount at any time outstanding not to exceed the greater of (a) $100.0 million and (b) 5.0% of Consolidated Net Tangible Assets (determined as of the date of incurrence and after giving effect to the use of proceeds therefrom).

Antero Midstream Partners will not incur, and will not permit Finance Corp. or any Subsidiary Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of Antero Midstream Partners, Finance Corp. or such Subsidiary Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Note Guarantee on substantially identical terms; provided, however, that no Indebtedness shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of Antero Midstream Partners, Finance Corp. or any such Subsidiary Guarantor solely by virtue of being unsecured or by virtue of being secured on a first or junior Lien basis.

For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (14) above, or is entitled to be incurred pursuant to Section 4.09(a) hereof, Antero Midstream Partners will be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. Indebtedness under Credit Facilities outstanding on the date on which Notes are first issued and authenticated under this Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt.

The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified Equity in the form of additional shares or units of the same class of Disqualified Equity will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Equity for purposes of this Section 4.09; provided, in each such case, that the amount of any such accrual, accretion or payment is included in Fixed Charges of Antero Midstream Partners as accrued to the extent required by the definition of such term. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that Antero Midstream Partners or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.

The amount of any Indebtedness outstanding as of any date will be:

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

(2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and

(3) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

(A) the Fair Market Value of such assets at the date of determination; and

(B) the amount of the Indebtedness of the other Person.

For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term debt, or first committed, in the case of revolving credit debt; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed (i) the principal amount of such Indebtedness being refinanced plus (ii) the aggregate amount of fees, underwriting discounts, premiums and other costs and expenses incurred in connection with such refinancing. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such respective Indebtedness is denominated that is in effect on the date of such refinancing.

Section 4.10 Asset Sales.

Antero Midstream Partners will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) Antero Midstream Partners (or the Restricted Subsidiary, as the case may be) receives consideration (including by way of relief from, or by any Person assuming responsibilities for, any liabilities, contingent or otherwise) at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of (such Fair Market Value to be determined on the date of contractually agreeing to such Asset Sale and which shall

give effect to the assumption by another Person of any liabilities as provided for in clause (2)(A)) below; and

(2) at least 75% of the consideration received in the Asset Sale by Antero Midstream Partners or such Restricted Subsidiary, together with the consideration received in all other Asset Sales by Antero Midstream Partners or any Restricted Subsidiary since the Issue Date (on a cumulative basis) is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash:

(A) any liabilities, as shown on Antero Midstream Partners’ most recent consolidated balance sheet, of Antero Midstream Partners or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantees) that are assumed by the transferee of any such assets pursuant to a novation agreement that releases Antero Midstream Partners or such Restricted Subsidiary from further liability;

(B) any securities, notes or other Obligations received by Antero Midstream Partners or any such Restricted Subsidiary from such transferee that are within 90 days after the Asset Sale (subject to ordinary settlement periods), converted by Antero Midstream Partners or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion;

(D) accounts receivable of a business retained by Antero Midstream Partners or any of its Restricted Subsidiaries, as the case may be, following the sale of such business, provided such accounts receivable (i) are not past due more than 60 days and (ii) do not have a payment date greater than 90 days from the date of the invoices creating such accounts receivable.

Within 365 days after the receipt of any Net Proceeds from an Asset Sale, Antero Midstream Partners (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds:

(1) to repay Senior Indebtedness of Antero Midstream Partners or its Restricted Subsidiaries (or to make an offer to repurchase or redeem such Indebtedness, provided that such repurchase or redemption closes within 45 days after the end of such 365-day period);

(3) to acquire all or substantially all of the properties or assets of, or any Capital Stock of, another Permitted Business, if, after giving effect to any such acquisition of Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary of Antero Midstream Partners;

(4) to make a capital expenditure in a Permitted Business; or

(5) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business.

Notwithstanding the foregoing, if within 365 days after the receipt of any Net Proceeds from an Asset Sale, Antero Midstream Partners (or the applicable Restricted Subsidiary, as the case may be) enters into a binding written agreement irrevocably committing Antero Midstream Partners or such Restricted Subsidiary to an application of funds of the kind described in clause (2), (3) or (4) of the preceding paragraph, and as to which the only condition to closing is the receipt of required governmental approvals

or, in the case of clause (3), the completion of required construction of the applicable asset(s), Antero Midstream Partners or such Restricted Subsidiary shall be deemed not to be in violation of the preceding paragraph. Any Net Proceeds that are applied pursuant to clause (2) or (4) of the preceding paragraph pursuant to any such binding agreement shall be deemed to have been applied for such purpose within such 365-day period so long as they are so applied within two years after the date of receipt of such Net Proceeds.

Pending the final application of any Net Proceeds, Antero Midstream Partners or any Restricted Subsidiary may temporarily reduce revolving credit borrowings (to the extent amounts corresponding to such reduction are permitted to be borrowed under this Indenture) or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture.

Any Net Proceeds from Asset Sales that are not applied or invested as provided in the second paragraph of this Section 4.10 will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $30.0 million, within five days thereof, Antero Midstream Partners will make an Asset Sale Offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, Antero Midstream Partners (or any Restricted Subsidiary) may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall (subject to the Depositary’s applicable procedures) select the Notes and the representative of such other pari passu Indebtedness will (subject to the Depositary’s applicable procedures) select such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

Antero Midstream Partners will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of Section 3.09 hereof or this Section 4.10, Antero Midstream Partners will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 hereof or this Section 4.10 by virtue of such compliance.

Section 4.11 Transactions with Affiliates.

(a) Antero Midstream Partners will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of Antero Midstream Partners involving more than $1,000,000 (each an “Affiliate Transaction”), unless:

(1) the Affiliate Transaction is on terms that are no less favorable to Antero Midstream Partners or the relevant Restricted Subsidiary than those that could have been obtained in a comparable transaction by Antero Midstream Partners or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Board of Directors of Antero Midstream Partners, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is fair to Antero Midstream Partners or the relevant Restricted Subsidiary from a financial or commercial point of view; and

(2) Antero Midstream Partners delivers to the Trustee with respect to any Affiliate Transaction (or series of related Affiliate Transactions) involving aggregate consideration in excess of $50.0 million, a resolution of the Board of Directors of Antero Midstream Partners set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) of this Section 4.11(a) and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of Antero Midstream Partners.

(b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.11(a) hereof:

(1) reasonable fees and compensation paid to or for the benefit of any employee, officer or director of Antero Midstream Partners, any of its Restricted Subsidiaries or the General Partner, and any employment agreement, employee benefit plan, officer or director indemnification agreement or any similar arrangement entered into by Antero Midstream Partners or any of its Restricted Subsidiaries existing on the Issue Date, or entered into thereafter in the ordinary course of business, and any indemnities or other transactions permitted or required by bylaw, statutory provisions or any of the foregoing agreements, plans or arrangements;

(2) transactions between or among Antero Midstream Partners or its Restricted Subsidiaries;

(3) transactions with a Person (other than an Unrestricted Subsidiary of Antero Midstream Partners) that is an Affiliate of Antero Midstream Partners solely because Antero Midstream Partners owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

(4) any issuance or sale of Equity Interests (other than Disqualified Equity) of Antero Midstream Partners to Affiliates of Antero Midstream Partners;

(5) Restricted Payments or Permitted Investments that do not violate Section 4.07 hereof;

(6) customary compensation, indemnification and other benefits made available to officers, directors or employees of Antero Midstream Partners, a Restricted Subsidiary of Antero Midstream Partners or the General Partner, including reimbursement or advancement of out-of-pocket expenses and provisions of officers’ and directors’ liability insurance;

(7) in the case of gathering, processing, compression, transporting, fractionating, waste water treatment or other operational contracts, any such contracts are entered into in the ordinary course of business on terms substantially similar to those contained in similar contracts entered into by Antero Midstream Partners or any Restricted Subsidiary and third parties, or if neither Antero Midstream Partners nor any Restricted Subsidiary has entered into a similar contract with a third party, that the terms are no less favorable than those available from third parties on an arm’s length basis, as determined in good faith by a majority of the disinterested members of the Board of Directors of Antero Midstream Partners;

(8) the existence of, or the performance by Antero Midstream Partners or any Restricted Subsidiary of its obligations under the terms of, any agreements that are described in the Antero Midstream Partners’ Annual Report on Form 10-K for the fiscal year ended December 31, 2018 under the heading “Certain Relationships and Related Transactions and Director Independence” to which it is a party as of the date of the Offering Memorandum and any amendments thereto and any similar agreements which it may enter into thereafter; provided, however, that the existence of,

or the performance by Antero Midstream Partners or any Restricted Subsidiary of its obligations under, any future amendment to such agreements or under any such similar agreements shall only be permitted by this clause (8) to the extent that the terms of any such amendment or new agreement, taken as a whole, are not less favorable to the Holders in any material respect as determined in good faith by a majority of the disinterested members of the Board of Directors of Antero Midstream Partners;

(9) if such Affiliate Transaction is with a Person in its capacity as a holder of Indebtedness or Equity Interests of Antero Midstream Partners or any of its Restricted Subsidiaries, a transaction in which such Person is treated no more favorably than the other holders of such Indebtedness or Equity Interests;

(10) (A) Guarantees by Antero Midstream Partners or any of its Restricted Subsidiaries of the performance of obligations of Unrestricted Subsidiaries or Joint Ventures in the ordinary course of business, except for Guarantees of Indebtedness in respect of borrowed money, and (B) pledges by Antero Midstream Partners or any Restricted Subsidiary of Capital Stock in Unrestricted Subsidiaries or Joint Ventures for the benefit of lenders or other creditors of Unrestricted Subsidiaries or Joint Ventures as contemplated by clause (13) of the definition of “Permitted Liens” so long as any such transaction described in this clause (B), if involving aggregate consideration in excess of $50.0 million, has been approved by a majority of the disinterested members of the Board of Directors of Antero Midstream Partners;

(11) any transaction in which the Antero Midstream Partners or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to Antero Midstream Partners or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of clause (1) of Section 4.11(a) hereof; and

(12) any transactions between Antero Midstream Partners or any Restricted Subsidiary and any Person, a director of which is also a director of Antero Midstream Partners or a Restricted Subsidiary, provided that such director abstains from voting as a director of Antero Midstream Partners or the Restricted Subsidiary, as applicable, in connection with the approval of the transaction.

Section 4.12 Liens.

Antero Midstream Partners will not and will not permit any Subsidiary Guarantor to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness, upon any of their property or assets, now owned or hereafter acquired, unless:

(1) in the case of Liens securing subordinated Indebtedness of Antero Midstream Partners or a Guarantor, the Notes or Note Guarantees, as applicable, are contemporaneously secured by a Lien on such property or assets on a senior basis to the subordinated Indebtedness so secured with the same priority that the Notes or Note Guarantees, as applicable, have to such subordinated Indebtedness until such time as such subordinated Indebtedness are no longer so secured by a Lien; and

(2) in the case of Liens securing Senior Indebtedness of Antero Midstream Partners or a Guarantor, the Notes or Note Guarantees, as applicable, are contemporaneously secured by a Lien on such property or assets on an equal and ratable basis with the Senior Indebtedness so secured until such time as such Senior Indebtedness is no longer so secured by a Lien.

Any Lien on property or assets of Antero Midstream Partners or a Guarantor created for the benefit of Holders of the Notes pursuant to the preceding paragraph shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged at such time as there are no other Liens of any kind (other than Permitted Liens) on such property or assets securing such Indebtedness.

Section 4.13 Limitations on Finance Corp. Activities.

Finance Corp. will not hold any material assets, become liable for any material obligations or engage in any significant business activities; provided, that Finance Corp. may be a co-obligor or guarantor with respect to Indebtedness if Antero Midstream Partners is an obligor on such Indebtedness and the net proceeds of such Indebtedness are received by Antero Midstream Partners, Finance Corp. or one or more Guarantors. At any time after Antero Midstream Partners is a corporation, Finance Corp. may consolidate or merge with or into Antero Midstream Partners or any other Restricted Subsidiary.

Section 4.14 Corporate Existence.

Subject to Article 5 hereof, Antero Midstream Partners shall do or cause to be done all things necessary to preserve and keep in full force and effect:

(1) its limited partnership existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of Antero Midstream Partners or any such Restricted Subsidiary; and

(2) the rights (charter and statutory), licenses and franchises of Antero Midstream Partners and its Restricted Subsidiaries; provided, however, that Antero Midstream Partners shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the General Partner shall determine that the preservation thereof is no longer desirable in the conduct of the business of Antero Midstream Partners and its Restricted Subsidiaries, taken as a whole.

Section 4.15 Offer to Repurchase Upon Change of Control.

(a) Upon the occurrence of a Change of Control, Antero Midstream Partners will make an offer (a “Change of Control Offer”) to each Holder of Notes to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but excluding, the date of purchase (the “Change of Control Payment”), subject to the rights of Holders of Notes on the relevant record date to receive interest due on an interest payment date that is on or prior to the date of purchase. Within 30 days following any Change of Control, Antero Midstream Partners will send a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating:

(1) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered will be accepted for payment;

(3) that any Note not tendered will continue to accrue interest;

(4) that, unless Antero Midstream Partners defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date;

(6) that Holders will be entitled to withdraw their election if the Paying Agent or depositary receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and

(7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

Antero Midstream Partners will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.15, Antero Midstream Partners will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by virtue of such compliance.

Antero Midstream Partners will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

The provisions described above that require Antero Midstream Partners to make a Change of Control Offer following a Change of Control will be applicable whether or not any other provisions of this Indenture are applicable.

(c) Notwithstanding anything to the contrary in this Section 4.15, Antero Midstream Partners will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, (2) notice of redemption has been given pursuant to Section 3.07 hereof, unless and until there is a default in payment of the applicable redemption price, or (3) in connection with or in contemplation of any Change of Control, Antero Midstream Partners makes an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered and not withdrawn at a cash price equal to or higher than the Change of Control Payment and purchases all Notes properly tendered and not withdrawn under the Alternate Offer.

(d) With respect to the Notes, in the event that Holders of not less than 90% of the aggregate principal amount of the outstanding Notes tender and do not withdraw such Notes in a Change of Control Offer or Alternate Offer and Antero Midstream Partners (or the third party making the Change of Control Offer as provided above) purchases all of the Notes validly tendered and not withdrawn by such Holders, the Issuers will have the right, upon not less than 15 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer or Alternate Offer described above, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to 101% of the aggregate principal amount of such Notes, plus accrued and unpaid interest on the Notes that remain outstanding to, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date).

Section 4.16 [Reserved.]

Section 4.17 [Reserved.]

Section 4.18 Additional Guarantees.

If, after the Issue Date, any wholly-owned Domestic Subsidiary (other than Finance Corp.) of Antero Midstream Partners that is not already a Guarantor Guarantees any other Indebtedness of either of the Issuers under a Credit Facility in an aggregate principal amount in excess of $50.0 million, then that Subsidiary will become a Guarantor by executing and delivering to the Trustee a supplemental indenture substantially in the form of Exhibit F hereto within 30 Business Days of the date on which it Guaranteed such Indebtedness; provided that the preceding shall not apply to Subsidiaries of Antero Midstream Partners that have been properly designated as Unrestricted Subsidiaries in accordance with this Indenture for so long as they continue to constitute Unrestricted Subsidiaries. Notwithstanding the preceding, any Note Guarantee of a Domestic Subsidiary that was incurred pursuant to this Section 4.18 will be released in accordance with Section 10.05 hereof.

Section 4.19 Designation of Restricted and Unrestricted Subsidiaries.

The Board of Directors of Antero Midstream Partners may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by Antero Midstream Partners and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and will

either reduce the amount available for Restricted Payments under Section 4.07 hereof or qualify as a Permitted Investment under one or more clauses of the definition of Permitted Investments, as determined by Antero Midstream Partners; provided that any designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

Any designation of a Subsidiary of Antero Midstream Partners as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of Antero Midstream Partners as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, Antero Midstream Partners will be in default of such covenant.

The Board of Directors of Antero Midstream Partners may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of Antero Midstream Partners; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of Antero Midstream Partners of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the Reference Period and (2) no Default or Event of Default would be in existence following such designation.

Section 4.20 Termination of Covenants.

(a) If at any time (i) the Notes are assigned an Investment Grade Rating from both Rating Agencies, (ii) no Default or Event of Default has occurred and is continuing under this Indenture and (iii) Antero Midstream Partners has delivered to the Trustee an Officers’ Certificate certifying to the foregoing provisions of this sentence (the “Termination Date”), Antero Midstream Partners and its Restricted Subsidiaries will no longer be subject to the following provisions of this Indenture: (1) Section 4.07; (2) Section 4.08; (3) Section 4.09; (4) Section 4.11; (5) Section 4.13; (6) Section 4.18; and (7) clause 4 of Section 5.01(a).

(b) However, Antero Midstream Partners and its Restricted Subsidiaries will remain subject to the other provisions of this Indenture, including : (1) Section 4.03; (2) Section 4.12; (3) Section 4.19; and (4) Section 5.01 (with the exception of clause (4) of Section 5.01(a)).

Section 6.02 Acceleration.

In the case of an Event of Default specified in clause (8) or (9) of Section 6.01 hereof, with respect to Finance Corp., Antero Midstream Partners or any Restricted Subsidiary of Antero Midstream Partners that is a Significant Subsidiary or any group of Restricted Subsidiaries of Antero Midstream Partners that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.

Upon any such declaration, the Notes shall become due and payable immediately.

The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of interest, or premium, if any, on, or the principal of, the Notes.

Section 6.03 Other Remedies.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium and interest, if any, on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium or interest on the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability (provided, however, that the Trustee shall be under no obligation to determine whether any action or inaction is unduly prejudicial to any Holder).

Section 6.06 Limitation on Suits.

A Holder may pursue a remedy with respect to this Indenture or the Notes only if:

(1) such Holder gives to the Trustee written notice that an Event of Default is continuing;

(2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer and, if requested, provide to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense;

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of security or indemnity; and

(5) during such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request.

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note.

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and interest and on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuers for the whole amount of principal of, premium and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09 Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuers (or any other obligor upon the Notes), their creditors or their property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

First: to the Trustee, the Agents and the Custodian, and their respective agents and attorneys for amounts due hereunder, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

Third: to the Issuers or to such party as a court of competent jurisdiction shall direct.

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.

Section 6.11 Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion

may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

The Trustee will not be responsible for and makes no representation as to the validity, adequacy or enforceability of this Indenture or the Notes, it shall not be liable for the acts or omissions of the Issuers or accountable for the Issuers’ use of the proceeds from the Notes or any money paid to the Issuers or upon the Issuers’ direction under any provision of this Indenture, it will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. The Trustee shall not be liable in its individual capacity for the Obligations evidenced by the Notes or this Indenture.

Section 7.05 Notice of Defaults.

If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee will send to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as it in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

Section 7.06 Reports by Trustee to Holders of the Notes.

(a) Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee will send to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA §313(a) (but if no event described in TIA §313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also will comply with TIA §313(b)(2). The Trustee will also transmit, in the manner prescribed in Section 12.02, all reports as required by TIA §313(c).

(b) A copy of each report at the time it is sent to the Holders of Notes will be sent by the Trustee to the Issuers and filed by the Trustee with the SEC and each stock exchange on which the Notes are listed in accordance with TIA §313(d). The Issuers will promptly notify the Trustee when the Notes are listed on any stock exchange.

Section 7.07 Compensation and Indemnity.

(a) The Issuers will pay to the Trustee from time to time compensation as agreed to in writing by the Trustee and the Issuers for its acceptance of this Indenture and services hereunder. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Issuers will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

(b) The Issuers and the Guarantors will indemnify, jointly and severally, the Trustee against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses (including

reasonable attorney’s fees and expenses and court costs) of enforcing this Indenture against the Issuers and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Issuers, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or willful misconduct, as determined by a court of competent jurisdiction in a non-appealable decision. The Trustee will notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuers will not relieve the Issuers or any of the Guarantors of their obligations hereunder. The Issuers or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Issuers will pay the reasonable fees and expenses of such counsel. Neither the Issuers nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

Such Lien will survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee.

(e) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(8) or (9) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

(a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08.

(b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuers. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuers in writing. The Issuers may remove the Trustee if:

(1) the Trustee fails to comply with Section 7.10 hereof;

(2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

(3) a custodian or public officer takes charge of the Trustee or its property; or

(4) the Trustee becomes incapable of acting.

(d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuers, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

(f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will send a notice of its succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuers’ obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee.

Section 7.09 Successor Trustee by Merger, etc.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act will be the successor Trustee.

ARTICLE 8
LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Issuers may, at their option and at any time, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes and Note Guarantees upon compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuers and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuers and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuers, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

(1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof;

(2) the Issuers’ obligations with respect to the Notes concerning issuing temporary Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust;

(3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuers’ and the Guarantors’ obligations in connection therewith; and

(4) this Article 8.

Subject to compliance with this Article 8, the Issuers may exercise their option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

Section 8.03 Covenant Defeasance.

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuers and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.03, 4.04(b), 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.18 and 4.19 hereof and clause (4) of Section 5.01 hereof with respect to the outstanding Notes, and the Guarantors will be released from their Obligations with respect to the Note Guarantees, on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder. For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Issuers and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(7) inclusive and Section 6.01(10) hereof will not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof:

(1) the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank or firm of independent public accountants, to pay the principal of, or interest and premium, if any, on the outstanding Notes on the stated date for payment thereof or on the applicable Redemption Date, as the case may be, and the Issuers must specify whether the Notes are being defeased to such stated date for payment or to a particular Redemption Date;

(2) in the case of an election under Section 8.02 hereof, the Issuers must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that:

(A) the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling; or

(B) since the Issue Date, there has been a change in the applicable federal income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of an election under Section 8.03 hereof, the Issuers must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness) or the grant of Liens securing such borrowings);

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture or any other agreement governing other Indebtedness being defeased, discharged or replaced) to which Antero Midstream Partners or any of its Subsidiaries is a party or by which Antero Midstream Partners or any of its Subsidiaries is bound;

(6) the Issuers must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuers with the intent of preferring the Holders of Notes over the other creditors of the Issuers or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Issuers; and

(7) the Issuers must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including either Issuer acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest but such money need not be segregated from other funds except to the extent required by law.

The Issuers will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Issuers from time to time upon the request of the Issuers any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to the Issuers.

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall, subject to applicable escheatment laws, be paid to the Issuers on their request or (if then held by the Issuers) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuers as trustee thereof, will thereupon cease; provided, however, that, if any Definitive Note is then outstanding, the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuers cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Issuers.

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuers’ and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in

accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Issuers make any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Issuers will be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

ARTICLE 9
AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders of Notes.

Notwithstanding Section 9.02 of this Indenture, the Issuers, the Guarantors and the Trustee may amend or supplement this Indenture or the Notes or the Note Guarantees without the consent of any Holder of Note:

(1) to cure any ambiguity, defect or inconsistency;

(4) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any such Holder;

(5) to conform the text of this Indenture, the Notes or the Note Guarantees to any provision of the “Description of notes” section of the Issuers’ Offering Memorandum to the extent that such provision was intended to be a verbatim recitation of a provision of this Indenture, the Notes or the Note Guarantees;

(6) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of the Issue Date;

(7) to allow any Guarantor to execute a supplemental indenture or a notation of a Note Guarantee with respect to the Notes or to reflect the release of a Note Guarantee in accordance with this Indenture;

(8) to secure the Notes or the Note Guarantees;

(9) to comply with the rules of any applicable securities depository;

(10) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA;

(11) to provide for the reorganization of Antero Midstream Partners as any other form of entity, in accordance with Section 5.01(a); or

(12) to appoint a successor trustee.

Upon the request of the Issuers, and upon receipt by the Trustee of the documents described in Section 9.05 hereof, the Trustee will join with the Issuers and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any

further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Section 9.02 With Consent of Holders of Notes.

Except as provided below in this Section 9.02, the Issuers, the Guarantors and the Trustee may amend or supplement this Indenture (including, without limitation, Sections 3.09, 4.10 and 4.15 hereof), the Notes and the Note Guarantees with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any), including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes, and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any), including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes. (Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02.) However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

(1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the redemption or repurchase of the Notes (other than provisions relating to minimum required notice of optional redemption or the provisions of Sections 3.09 and 4.10 or Section 4.15 hereof);

(3) reduce the rate of or change the time for payment of interest, including default interest on any Note;

(4) waive a Default or Event of Default in the payment of principal of, or interest or premium, if any, on the Notes (except a rescission of acceleration of the Notes by the Holders of a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration);

(5) make any Note payable in money other than that stated in the Notes;

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of, principal of, or interest or premium, if any, on, the Notes (other than as permitted by clause (7) below);

(7) waive a redemption or repurchase payment with respect to any Note (other than a payment required by Sections 3.09 and 4.10 or Section 4.15 hereof);

(8) release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or

(9) make any change in the preceding amendment, supplement and waiver provisions.

Upon the request of the Issuers accompanied by a resolution of their respective Boards of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.05 hereof, the Trustee will join with the Issuers and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture.

It is not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuers will send to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuers to send such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver.

Section 9.03 Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms (except as provided in the second succeeding paragraph) and thereafter binds every Holder.

The Issuers may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then notwithstanding the second to last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies) and only those Persons, shall be entitled to consent to such amendment or waiver or revoke any consent previously given, whether or not such Persons continue to be Holders after such record date.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of the clauses (1) through (9) of Section 9.02, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same indebtedness as the consenting Holder’s Note.

Section 9.04 Notation on or Exchange of Notes.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuers in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.

Section 9.05 Trustee to Sign Amendments, etc.

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

Section 9.06 Effect of Supplemental Indentures.

Upon the execution of any supplemental indenture under this Article 9, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

ARTICLE 10
NOTE GUARANTEES

Section 10.01 Guarantee.

(a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, that:

(1) the principal of, premium, if any, and interest on, the Notes will be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuers to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever and covenants that its Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Issuers, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either

the Issuers or the Guarantors, any amount paid by either to the Trustee or such Holder, each Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Section 10.01, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purposes of this Section 10.01. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

Section 10.02 Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirm that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.03 Execution and Delivery of Notation of Note Guarantee.

To evidence its Note Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture (including any supplement thereto) will be executed on behalf of such Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

If an Officer whose signature is on this Indenture or on the notation of its Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which such notation of its Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Guarantors.

In the event that the Issuers or any of Antero Midstream Partners’ Restricted Subsidiaries creates or acquires any wholly-owned Domestic Subsidiary after the date of this Indenture, if required by Section

4.18 hereof, the Issuers will cause such Domestic Subsidiary to comply with the provisions of Section 4.18 hereof and this Article 10, to the extent applicable.

Section 10.04 Guarantors May Consolidate, etc., on Certain Terms.

Except as otherwise provided in Section 10.05 hereof, a Guarantor may not sell or otherwise dispose of all or substantially all of its properties or assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Issuers or another Guarantor, unless:

(a) immediately after giving effect to such transaction, no Default or Event of Default exists; and

(b) either:

(1) the Person acquiring the properties or assets in any such sale or disposition or the Person formed by or surviving any such consolidation or merger is a Guarantor, or assumes all the obligations of that Guarantor under this Indenture and its Note Guarantee, pursuant to a supplemental indenture in form reasonably satisfactory to the Trustee; or

(2) the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture, if any.

In case of any such consolidation, merger, sale or other disposition and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and reasonably satisfactory in form to the Trustee, of such obligations of the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the notations of Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Issuers and delivered to the Trustee. The Note Guarantee so issued by such successor Person will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though such Note Guarantee had been issued at the date of the execution hereof.

Section 10.05 Releases.

(a) In the event of any sale or other disposition (i) of all or substantially all of the properties or assets of any Guarantor, by way of merger, consolidation or otherwise, to a Person that is not (either before or after giving effect to such transactions) Antero Midstream Partners or a Restricted Subsidiary of Antero Midstream Partners, or (ii) of all of the Capital Stock of any Guarantor after which the applicable Guarantor is no longer a Restricted Subsidiary of Antero Midstream Partners, then such Guarantor will be released and relieved of any obligations under its Note Guarantee and all of its other Obligations under this Indenture; provided that such sale or other disposition does not violate the applicable provisions of Section 4.10 hereof.

(b) Upon designation of any Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture, such Guarantor will be released and relieved of any obligations under its Note Guarantee and all of its other Obligations under this Indenture.

(c) Upon release or discharge of the Guarantee by any Guarantor with respect to Indebtedness under a Credit Facility or the Guarantee that resulted in the creation of a Note Guarantee, such Guarantor will be released and relieved of any obligations under its Note Guarantee and its other Obligations under

this Indenture; provided, however, that if, at any time following such release or discharge, that Guarantor later Guarantees Indebtedness of either Issuer under a Credit Facility, then such Guarantor shall be required to provide a Note Guarantee at such time if required in accordance with Section 4.18 hereof.

(d) Upon Legal Defeasance or Covenant Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance with Article 11 hereof, each Guarantor will be released and relieved of any obligations under its Note Guarantee and all of its other Obligations under this Indenture.

(e) Upon the merger or consolidation of any Guarantor with and into an Issuer or another Guarantor that is the surviving Person in such merger or consolidation, or upon the liquidation or dissolution of such Guarantor, such Guarantor will be relieved of any obligations under its Note Guarantee and all of its other Obligations under this Indenture.

(f) Upon delivery by the Issuers to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that the conditions of this Section 10.05 for a release have been satisfied, the Trustee will execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Note Guarantee and all of its other Obligations under this Indenture.

(g) Any Guarantor not released from its obligations under its Note Guarantee and all of its other Obligations under this Indenture as provided in this Section 10.05 will remain liable for the full amount of principal of and interest, and premium, if any, on the Notes and for the other Obligations of such Guarantor under this Indenture as provided in this Article 10.

ARTICLE 11
SATISFACTION AND DISCHARGE

Section 11.01 Satisfaction and Discharge.

This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder (except as to surviving rights of registration of transfer or exchange of the Notes and as otherwise specified in this Indenture), when:

(1) either:

(A) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Issuers, have been delivered to the Trustee for cancellation; or

(B) all Notes that have not been delivered to the Trustee for cancellation have become due and payable or will become due and payable within one year by reason of the sending of a notice of redemption or otherwise, and the Issuers or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, without consideration of any reinvestment of interest, in the opinion of a nationally recognized investment bank or firm of independent public accountants if the deposit includes any Government Securities, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest, if any, to the date of Stated Maturity or redemption;

(2) in the case of clause (1)(B) above, no Event of Default has occurred and is continuing on the date of such deposit (other than an Event of Default resulting from the borrowing of funds to be applied to such deposit and any similar deposit relating to other Indebtedness and, in each case, the granting of Liens to secure such borrowings), and such deposit will not result in a breach or violation of, or constitute a default under, any material agreement or instrument to which Antero Midstream Partners or any of its Subsidiaries is a party or by which Antero Midstream Partners or any of its Subsidiaries is bound (other than with respect to the borrowing of funds to be applied concurrently to make the deposit required to effect such satisfaction and discharge and any similar concurrent deposit relating to other Indebtedness, and in each case the granting of Liens to such borrowings);

(3) the Issuers or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and

(4) the Issuers have delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at Stated Maturity or on the Redemption Date, as the case may be.

In addition, the Issuers must deliver (a) an Officers’ Certificate stating that all conditions precedent set forth in clauses (1) through (4) above have been satisfied, and (b) an Opinion of Counsel to the Trustee (which Opinion of Counsel may be subject to customary assumptions and qualifications), stating that all conditions precedent to satisfaction and discharge set forth in Section 11.01(2) and (4) have been satisfied; provided that the Opinion of Counsel with respect to 11.01(2) above may be to the knowledge of such counsel.

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section 11.01, the provisions of Sections 11.02 and 8.06 hereof will survive. In addition, nothing in this Section 11.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 11.02 Application of Trust Money.

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including either Issuer acting as Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuers’ and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 11.01; provided that if the Issuers have made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of their obligations, the Issuers shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

The Issuers will pay interest semi-annually in arrears on March 1 and September 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”).

Interest will be computed on the basis of a 360-day year of twelve 30-day months.

(2) METHOD OF PAYMENT. The Issuers will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the February 15 or August 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium and interest at the office or agency of the Issuers maintained for such purpose within or without the City and State of New York, or, at the option of the Issuers, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest and premium on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuers or the Paying Agent to an account in the United States. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured obligations of the Issuers. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder.

A-4

(5) OPTIONAL REDEMPTION.

(a) Except pursuant to paragraphs (b), (c) and (d) of this Section 5, the Notes will not be redeemable at the Issuers’ option prior to March 1, 2022.

Unless the Issuers default in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable Redemption Date.

(b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time prior to March 1, 2022, the Issuers may on any one or more occasions redeem, upon prior notice in accordance with Section 3.02 of the Indenture, up to 35% of the aggregate principal amount of Notes (including any Additional Notes) issued under this Indenture at a redemption price of 105.750% of the principal amount thereof, plus accrued and unpaid interest to, but excluding, the Redemption Date (subject to the right of Holders of Notes on the relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date), with an amount of cash not greater than the net cash proceeds of one or more Equity Offerings by Antero Midstream Partners; provided that at least 65% of the aggregate principal amount of Notes (including any Additional Notes) issued under this Indenture (excluding Notes held by Antero Midstream Partners and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and the redemption occurs within 180 days of the date of the closing of such Equity Offering.

(c) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time prior to March 1, 2022, the Issuers may also redeem all or a part of the Notes, upon prior notice in accordance with Section 3.02 of the Indenture, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest to, but excluding, the Redemption Date, subject to the rights of Holders on the relevant record date to receive interest due on an interest payment date that is on prior to the Redemption Date.

(d) The Issuers may also redeem the Notes as provided in Section 4.15(d) of the Indenture, on the terms and subject to the conditions set forth therein.

For purposes of this Paragraph 5, “Applicable Premium” means, with respect to any Note at the time of determination, the greater of: (1) 1.00% of the principal amount of the Note; or (2) the excess of: (a) the present value at such time of (i) the redemption price of the Note at March 1, 2022 (such redemption price being set forth in the table appearing in Section 3.07(c) of the Indenture) plus (ii) all required interest payments due on the Note through March 1, 2022 (excluding accrued but unpaid interest to the Redemption Date), computed using a discount rate equal to the Treasury Rate as of such Redemption Date plus 50 basis points; over (b) the principal amount of the Note, if greater. “Treasury Rate” means, as of the time of computation, the yield to maturity as of such time of United States Treasury securities with a constant

A-5

maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) that has become publicly available at least two Business Days prior to the Redemption Date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from the Redemption Date to March 1, 2022; provided, however, that if the period from the Redemption Date to March 1, 2022, is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used.

(6) MANDATORY REDEMPTION.

The Issuers are not required to make mandatory redemption or sinking fund payments with respect to the Notes. The Issuers may acquire the Notes by means other than a redemption, whether pursuant to a tender offer, open market purchase or otherwise, so long as the acquisition does not violate the terms of the Indenture.

(7) REPURCHASE AT THE OPTION OF HOLDER.

(a) If there is a Change of Control, Antero Midstream Partners will be required to make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date that is on or prior to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, Antero Midstream Partners will send a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture.

(b) If Antero Midstream Partners or a Restricted Subsidiary of Antero Midstream Partners consummates any Asset Sales, within five days of each date on which the aggregate amount of Excess Proceeds exceeds $30.0 million, Antero Midstream Partners will commence an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in Section 4.10 of the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (an “Asset Sale Offer”) to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount plus accrued and unpaid interest to the date of purchase, in accordance with the procedures set forth in Section 3.09 of the Indenture. If any Excess Proceeds remain after consummation of an Asset Sale Offer, Antero Midstream Partners (or any Restricted Subsidiary) may use such Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall (subject to the Depositary’s applicable procedures) select the Notes and the representative of such other pari passu Indebtedness will (subject to the Depositary’s applicable procedures) select such other pari passu Indebtedness to be purchased on a pro rata basis.

(c) Holders of Notes that are the subject of a Change of Control Offer or an Asset Sale Offer will receive an offer to purchase from the Issuers prior to any related purchase date, and Holders of Definitive Notes may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.

Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 and in excess of $2,000, unless all of the Notes held by a Holder are to be redeemed. Notice of any redemption of the Notes (including upon an Equity Offering or in connection with a transaction (or series of related transactions) that constitute a Change of Control) may, at the Issuers’ discretion, be given prior to the completion thereof and be subject to one or more conditions precedent, including, but not limited to, completion of the related Equity Offering or Change of Control. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuers’ discretion, the Redemption Date may be delayed until such time (including more than 60 days after the date the notice of redemption was delivered) as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date so delayed, or such notice may be rescinded at any time in the Issuers’ discretion if in the good faith judgment of the Issuers any or all of such conditions will not be satisfied.

(9) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture.

The Issuers need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Issuers need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.
