 1.
Interest. Dune Energy, Inc., a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Note at the rate per annum shown above. Interest on the Note will accrue from the most recent date
on which interest has been paid or, if no interest has been paid, from and including the Issue Date. The Company will pay interest semi-annually in arrears on each Interest Payment Date, commencing December 1, 2007. Interest will be computed on
the basis of a 360-day year comprised of twelve 30-day months. The Company will pay interest on overdue principal at 1% per annum in excess of the above rate and will pay interest on overdue installments of interest at such higher rate to the
extent lawful. Additional Interest may accrue on this Note in certain circumstances pursuant to the Registration Rights Agreement and all references to “interest” in this Note shall include any Additional Interest due on this Note pursuant
to the terms of the Registration Rights Agreement. 
 2. Method of Payment. The Company shall pay interest on the Notes (except
defaulted interest) to the Persons who are the registered Holders at the close of business on the Record Date immediately preceding the Interest Payment Date even if the Notes are cancelled on registration of transfer or registration of exchange
after such Record Date, and on or before such Interest Payment Date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Company shall pay principal and interest in money of the United States that at the time of payment
is legal tender for payment of public and private debts (“U.S. Legal Tender”). However, the Company may pay principal and interest by check payable in such U.S. Legal Tender. The Company may deliver any such interest payment to the
Paying Agent or to a Holder at the Holder’s registered address. 
 3. Paying Agent and Registrar. Initially, The Bank of New York
(the “Trustee”) will act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar or co-Registrar without notice to the Holders. 
 4. Indenture. The Notes and the Guarantees were issued under an Indenture, dated as of May 15, 2007 (the “Indenture”), among the Company, the Guarantors named therein, the Trustee and the
Collateral Agent. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture
Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”), as in effect on the date of the Indenture until such time as the Indenture is qualified under the TIA, and thereafter as in effect on the date on which the
Indenture is qualified under the TIA. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to the Indenture and the TIA for a statement of such terms. The Notes are senior
secured obligations of the Company. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same may be amended from time to time. 
 5. Redemption. 
 (a) Optional
Redemption On or After June 1, 2010. The Notes are not redeemable before June 1, 2010. Thereafter, the Company may redeem the Notes, at its option, in 








 
whole or in part, upon not less than 30 nor more than 60 days’ notice, at a redemption price at the redemption prices (expressed as percentages of
principal amount) set forth below plus accrued and unpaid interest to (but not including) the redemption date, if redeemed during the twelve-month period beginning on June 1 of the years set forth below: 
  

				
	 Year
	  	Percentage	 
	 2010
	  	105.250	%
	 2011 and thereafter
	  	100.000	%

 In addition, the Company must pay accrued and unpaid interest and Additional Interest, if any, on
the Notes redeemed to the Redemption Date. 
 (b) Optional Redemption Upon Equity Offerings. At any time, or from time to time, prior
to June 1, 2010, the Company may, at its option, use an amount not to exceed the net cash proceeds of one or more Equity Offerings to redeem up to 35% of the aggregate principal amount of the Notes (which includes Additional Notes, if any)
originally issued under this Indenture at a redemption price of 110.500% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon, to the Redemption Date; provided that: 
 (1) at least 65% of the principal amount of Notes (which includes Additional Notes, if any) originally issued under this Indenture remains
outstanding immediately after any such redemption; and 
 (2) the Company makes such redemption not more than 120 days after
the consummation of any such Equity Offering. 
 (c) Mandatory Redemption. The Company is not required to make any mandatory
redemption or sinking fund payments with respect to the Notes. 
 6. Notice of Redemption. Notice of redemption will be mailed by
first-class mail at least 30 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at such Holder’s registered address with a copy to the Trustee and Paying Agent. If fewer than all of the Notes are to
be redeemed, at any time, selection of Notes for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed, or, if the Notes are not so listed, on
a pro rata basis, by lot or by such method as the Trustee deems to be fair and appropriate; provided, that if any such partial redemption is made with the proceeds of an Equity Offering, the Trustee will select the Notes only on
a pro rata basis or on as nearly a pro rata basis as is practicable (subject to DTC procedures), unless such method is otherwise prohibited. Notes in denominations of $1,000 may be redeemed only in whole. The Trustee may
select for redemption portions (equal to $1,000 or any integral multiple thereof) of the principal amount of Notes that have denominations larger than $1,000. 
 Except as set forth in the Indenture, if monies for the redemption of the Notes called for redemption shall have been deposited with the Paying Agent for redemption on such Redemption Date sufficient to pay such
Redemption Price plus accrued and unpaid interest and 








 
Additional Interest, if any, the Notes called for redemption will cease to bear interest from and after such Redemption Date, and the only remaining right of
the Holders of such Notes will be to receive payment of the Redemption Price plus accrued and unpaid interest and Additional Interest, if any, as of the Redemption Date upon surrender to the Paying Agent of the Notes redeemed. 
 7. Offers to Purchase. Sections 4.15 and 4.16 of the Indenture provide that upon the occurrence of a Change of Control and after
certain Asset Sales, respectively, and subject to further limitations contained therein, the Company will make an offer to purchase certain amounts of the Notes in accordance with the procedures set forth in the Indenture. 
 8. Denominations; Transfer; Exchange. The Notes are in registered form, without coupons, in denominations of $1,000 and integral multiples
thereof. A Holder shall register the transfer of or exchange of Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes, fees or
similar governmental charges payable in connection therewith as permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Notes or portions thereof selected for redemption. 
 9. Persons Deemed Owners. The registered Holder of a Note shall be treated as the owner of it for all purposes. 
 10. Unclaimed Money. If money for the payment of principal or interest remains unclaimed for two years, the Trustee and the Paying Agent may pay
the money without interest thereon back to the Company. After that, all liability of the Trustee and such Paying Agent with respect to such money shall cease. 
 11. Discharge Prior to Redemption or Maturity. If the Company at any time deposits with the Trustee U.S. Legal Tender or U.S. Government Obligations sufficient to pay the principal of and interest on the Notes
to redemption or stated maturity and complies with the other provisions of the Indenture relating thereto, the Company will be discharged from certain provisions of the Indenture and the Notes (including certain covenants, but excluding its
obligation to pay the principal of and interest and Additional Interest, if any, on the Notes). 
 12. Amendment; Supplement; Waiver.
Subject to certain exceptions, the Indenture, the Notes, the Guarantees and the Collateral Agreements may be amended or supplemented with the written consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding,
and any existing Default or Event of Default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding. Without consent of any Holder, the
parties thereto may amend or supplement the Indenture, the Notes, the Guarantees, or the Collateral Agreements to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Notes in addition to or in place of
certificated Notes, provide for the assumption of the Company’s or any Guarantor’s obligations in accordance with Section 5.01 and Section 10.04 of the Indenture, make any other change that would provide any
additional rights or benefits to the Holders that does not adversely affect the legal rights of any Holder of a Note, to comply with the TIA, to allow for additional guarantees, if necessary, in connection 








 
with any addition or release of Collateral permitted under the Indenture or the Collateral Agreements, to release a Guarantor from its Guarantee as permitted
by the Indenture and to conform the text of the Indenture, the Collateral Agreements, the Notes and the Guarantees to the Offering Circular if necessary. 
 13. Restrictive Covenants. The Indenture imposes certain limitations on the ability of the Company and its Restricted Subsidiaries to, among other things, incur additional Indebtedness or grant Liens, make
payments in respect of their Capital Stock or certain Indebtedness, enter into transactions with Affiliates, create dividend or other payment restrictions affecting Subsidiaries, merge or consolidate with any other Person, sell, assign, transfer,
lease, convey or otherwise dispose of all or substantially all of its assets or adopt a plan of liquidation. Such limitations are subject to a number of important qualifications and exceptions. The Company must annually report to the Trustee on
compliance with such limitations. 
 14. Successors. When a successor assumes, in accordance with the Indenture, all the obligations
of its predecessor under the Notes, the Guarantees and the Indenture, the predecessor will be released from those obligations. 
 15.
Defaults and Remedies. If an Event of Default occurs and is continuing (other than certain events of bankruptcy involving the Company), the Trustee or the Holders of at least 25% in aggregate principal amount of outstanding Notes may declare
all the Notes to be due and payable in the manner, at the time and with the effect provided in the Indenture. Holders of Notes may not enforce the Indenture except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture
or the Notes unless it has received reasonable indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default in payment of principal or interest) if it determines that withholding notice is in
their interest. 
 16. Trustee Dealings with Company. Subject to the terms of the TIA and the Indenture, the Trustee under the
Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company, its Subsidiaries or their respective Affiliates as if it were not the Trustee. 
 17. No Recourse Against Others. No past, present or future affiliate, director, officer, employee, incorporator or holder of any equity interests
in the Company or a Guarantor or any direct or indirect parent corporation of the Company or a Guarantor, as such, will have any liability for any obligations of the Company or a Guarantor under the Notes, the Guarantees or the Indenture, or for any
claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Each
of the parties hereto acknowledge that such waiver may not be effective to waive liabilities under the federal securities laws. 







 18. Guarantees. Payment of principal and interest (including interest on overdue principal and
overdue interest, if lawful), is unconditionally and irrevocably guaranteed, jointly and severally, by each of the Guarantors. 
 19.
Authentication. This Note shall not be valid until the Trustee or Authenticating Agent manually signs the certificate of authentication on this Note. 
 20. Governing Law. THIS NOTE, THE INDENTURE, THE GUARANTEES AND THE COLLATERAL AGREEMENTS (OTHER THAN THE MORTGAGES) SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS
APPLIED TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS. EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS NOTE, THE INDENTURE, THE GUARANTEES AND THE COLLATERAL AGREEMENTS (OTHER THAN THE MORTGAGES) OR THE TRANSACTIONS CONTEMPLATED BY THIS NOTE.

the Collateral Agreements. The actions of the Trustee and the Holders of the Notes secured by such liens and the application of proceeds from the enforcement of any remedies with respect to such Collateral are limited pursuant to the terms of the
Collateral Agreements. 
 23. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security
Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes as a convenience to the Holders of the Notes. No representation is made as to the accuracy of such numbers as printed on the Notes and reliance may be placed
only on the other identification numbers printed thereon.
