Capitalized terms used herein have the meanings
assigned to them in the Indenture referred to below unless otherwise indicated.


 


(1)INTEREST. Vanguard
Natural Resources, LLC, a Delaware limited liability company (the “Company”), and VNR Finance Corp., a Delaware
corporation (“Finance Corp.” and together with the Company, the “Issuers”), jointly and severally
promise to pay or cause to be paid interest on the principal amount of this Note at 7.0% per annum from February 10, 2016 until
maturity. The Issuers will pay interest semi-annually in arrears on February 15 and August 15 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 on the
Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of
issuance; provided that, if there is no existing Default in the payment of interest, and if this Note is authenticated between
a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be August 15, 2016. The Issuers
will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium,
if any, from time to time on demand at a rate that is 1% per annum higher than the then applicable interest rate on the Notes to
the extent lawful; they will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest, if any (without regard to any applicable grace period), from time to time on demand at the same rate
to the extent lawful.


  


Interest will be computed on the
basis of a 360-day year comprised 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 1 and August 1 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, if any, and interest, if any, at the office or agency
of the Issuers maintained for such purpose within 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, or premium or interest,
if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company
or the Paying Agent. 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.


 






      


     


    




 


(3)MATURITY. The Notes
will mature on the earlier of (i) February 15, 2023 or (ii) December 31, 2019 if, prior to December 24, 2019, the Issuers have
not repurchased, redeemed or otherwise repaid in full all Existing Unsecured Notes outstanding at that time in excess of $50.0
million in aggregate principal amount and, to the extent the Issuers repurchased, redeemed or otherwise repaid the Existing Unsecured
Notes with the proceeds of Indebtedness, such Indebtedness has a final maturity date no earlier than the date that is 91 days after
February 15, 2023 (and provided that such Indebtedness requires no amortization of principal or mandatory prepayments, repurchases
or redemptions other than provisions similar to those described in Sections 4.10 and 4.15 of the Indenture).


  


(4)PAYING AGENT AND REGISTRAR.
Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuers
may change the Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act as Paying
Agent or Registrar.





 


(5)INDENTURE. The Issuers
issued the Notes under an Indenture dated as of February 10, 2016 among the Issuers, the Guarantors and the Trustee (the “Indenture”).
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 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 Indenture does not limit the aggregate principal
amount of Notes that may be issued thereunder.


  


(6)OPTIONAL REDEMPTION.





 


(a)At any time prior to February
15, 2019, the Issuers may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes issued under
the Indenture, with an amount of cash not greater than the net cash proceeds of an Equity Offering by the Company, upon notice
as provided in the Indenture, at a redemption price equal to 107.000% of the principal amount of the Notes redeemed, plus accrued
and unpaid interest, if any, to the date of redemption (subject to the rights of Holders on the relevant record date to receive
interest on the relevant Interest Payment Date), provided that:


 


(i)at least 65% of the aggregate
principal amount of Notes originally issued under the Indenture (excluding Notes held by the Company and its Subsidiaries) remains
outstanding immediately after the occurrence of such redemption; and


 


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


 






      


     


    

 


(b)At any time prior to February
15, 2019, the Issuers may on any one or more occasions redeem all or a part of the Notes, upon notice as provided in the Indenture,
at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus the Applicable Premium as of, and accrued
and unpaid interest to, the date of redemption, subject to the rights of Holders on the relevant record date to receive interest
due on the relevant Interest Payment Date.


 


(c)The Issuers may redeem all
(but not a portion of) the Notes when permitted by, and pursuant to the conditions in, Section 4.15(f) of the Indenture.


 


(d)Except pursuant to the preceding
paragraphs, the Notes will not be redeemable at the Issuers’ option prior to February 15, 2019.


 


(e)On and after February 15,
2019, the Issuers may on any one or more occasions redeem all or a part of the Notes, upon notice as provided in the Indenture,
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 the applicable redemption date, subject to the rights of Holders on the relevant record date to receive
interest on the relevant Interest Payment Date, if redeemed during the twelve-month period beginning on February 15 of the years
indicated below:


 


	Year	 	Percentage	 
	2019	 	 	105.250	%
	2020	 	 	103.500	%
	2021	 	 	101.750	%
	2022 and thereafter	 	 	100.000	%



 


(7)MANDATORY REDEMPTION.
The Issuers are not required to make mandatory redemption or sinking fund payments with respect to the Notes.


  


(8)REPURCHASE AT THE OPTION
OF HOLDER.


  


(a)If there is a Change of Control,
the Company will be required to make an offer (a “Change of Control Offer”) to each Holder to repurchase all
or any part (equal to $1,000 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, if any, thereon 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 (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company will mail
a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture.


 


(b)If the Company or a Restricted
Subsidiary of the Company consummates any Asset Sales, within five days of each date on which the aggregate amount of Excess Proceeds
exceeds $20.0 million, the Company will make an Asset Sale Offer to all Holders of Notes and, if required by the terms of other
Parity Lien Debt, to all holders of such other Parity Lien Debt to purchase, prepay or redeem, on a pro rata basis, the maximum
principal amount of Notes and such other Parity Lien Debt (plus all accrued interest and the amount of all fees and expenses, including
premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed 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, prepayment or redemption, subject to the rights of Holders of Notes on the relevant record date to receive interest due
on the relevant Interest Payment Date, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset
Sale Offer, the Company or any Restricted Subsidiary may use those Excess Proceeds for any purpose not otherwise prohibited by
the Indenture. If the aggregate principal amount of Notes and other Parity Lien Debt, if applicable, tendered in such Asset Sale
Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other Parity Lien Debt to be purchased
on a pro rata basis (except as provided in Section 4.10 of the Indenture), based on the amounts tendered. Upon completion of each
Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. Holders of Definitive Notes that are the subject of an offer
to purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes
purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.


 






      


     


    

 


(9)NOTICE OF REDEMPTION.
At least 30 days but not more than 60 days before a redemption date, the Issuers will mail or cause to be mailed, by first class
mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices
may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes
or a satisfaction and discharge of the Indenture pursuant to Article VIII or XI thereof. Notes and portions of Notes selected will
be in amounts of $1,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed,
the entire outstanding amount of Notes held by such Holder shall be redeemed.





 


(10)DENOMINATIONS, TRANSFER,
EXCHANGE. The Notes are in registered form in denominations of $1,000 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 Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuers may require a
Holder to pay any taxes or similar governmental charge permitted by 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 next succeeding Interest Payment Date.


 





(11)PERSONS DEEMED OWNERS.
The registered Holder of a Note may be treated as the owner of it for all purposes. Only registered Holders have rights under the
Indenture.





 


(12)AMENDMENT, SUPPLEMENT
AND WAIVER. Subject to certain exceptions, the Indenture, the Notes or the Note Guarantees may be amended or supplemented with
the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes including Additional Notes,
if any, voting as a single class, and any existing Default or Event of Default or compliance with any provision of the Indenture

the then outstanding Notes including Additional Notes, if any, voting as a single class, in each case in addition to any required

ambiguity, defect or inconsistency; to provide for uncertificated Notes in addition to or in place of certificated Notes; to provide
for the assumption of the Issuers’ or a Guarantor’s obligations to Holders of the Notes and Note Guarantees by a successor

the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA; to conform the text
of the Note Documents to any provision of the “Description of Notes” section of the Issuers’ Offering Memorandum

any of its Restricted Subsidiaries which default is a Payment Default or results in the acceleration of such Indebtedness prior

by a court or courts of competent jurisdiction aggregating in excess of $15.0 million (to the extent not covered by insurance by

to certain limitations, 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. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except
a Default or Event of Default relating to the payment of principal, or premium or interest, if any) if it determines that withholding
notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to
the Trustee may, on behalf of all the Holders, rescind an acceleration or waive an existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of Default in the payment of principal of, or premium or
interest, if any, on, the Notes (including in connection with an offer to purchase any Notes). The Issuers are required to deliver
to the Trustee annually an Officers’ Certificate regarding compliance with the Indenture, and the Issuers are required, upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a written statement specifying such Default or Event
of Default.

under the Notes, the Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations
