WARRANT EXERCISE AGREEMENT

      This Warrant Exercise Agreement (this "Agreement") is dated as of April
30, 2007, among Rand Logistics, Inc., a Delaware corporation (the "Company"),
and the warrant holders listed on Schedule 1 hereto (each, a "Warrant Holder"
and collectively, the "Warrant Holders").

      WHEREAS, subject to the terms and conditions set forth in this Agreement,
in order to induce the Warrant Holders to exercise certain of the Company's
outstanding publicly traded warrants ("Warrants") held by the Warrant Holders as
of the date of this Agreement, the Company is willing to waive receipt of $0.50
of the exercise price of such Warrants, thereby effectively reducing the

      NOW, THEREFORE, for good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, the Company and the Warrant Holders
agree as follows:

                              EXERCISE OF WARRANTS

      1.1 Promptly following execution of this Agreement, but in no event later
than 4:00 p.m. (New York City time) on the second business day immediately after
the date hereof (such two business day period, the "Discount Exercise Period"),
each Warrant Holder shall cause the number of Warrants listed opposite such
Warrant Holder's name on Schedule 1 hereto (the "Subject Warrants") to be
exercised in accordance with the terms and procedures for exercise provided in
the Warrants.

      1.2 The Company shall direct Continental Stock Transfer & Trust Company,
as warrant agent for the Warrants (a) to accept as valid, exercises of the
Subject Warrants during the Discount Exercise Period at an exercise price of
$4.50 provided that the exercise otherwise complies with all applicable
requirements for the exercise of Warrants as provided by the terms of the
Warrants and (b) subject to satisfaction of the conditions to issuance of shares
of Common Stock (as defined in the Warrant) set forth in the Company's
Certificate of Incorporation pertaining to citizenship of holders of Common
Stock, to issue one shares of Common Stock in respect of each Subject Warrant so
exercised.

      1.3 The respective obligations of the parties set forth herein shall be
subject to absence during the Discount Exercise Period of (a) any formal
suspension in trading in the Common Stock, (b) any order issued by a court,
arbitrator or governmental authority restraining the transactions contemplated
by this Agreement, and (c) any pending proceeding challenging the transactions
contemplated by this Agreement.

                                  ARTICLE II.

            (a) Organization; Authority. Such Warrant Holder is an entity duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization with the requisite power and authority to enter

independently evaluated the merits of its decision to exercise the Subject
Warrants as provided in this Agreement, such decision has been independently
made by such Warrant Holder and such Warrant Holder confirms that it has only

                                  ARTICLE III.
                                  MISCELLANEOUS

      3.1 Securities Laws Disclosure. Within the time period required by the

the parties with respect to the subject matter hereof and supersede all prior
agreements and understandings, oral or written, with respect to such matters,
which the parties acknowledge have been merged into this Agreement.

      3.3 Amendments; Waivers. No provision of this Agreement may be amended or
waived except in a written instrument signed by the waiving party or, in the
case of an amendment, by the Company and the Warrant Holder or Warrant Holders
adversely affected by such amendment. No waiver of any default with respect to
any provision, condition or requirement of this Agreement shall be deemed to be
a continuing waiver in the future or a waiver of any subsequent default or a
waiver of any other provision, condition or requirement hereof, nor shall any
delay or omission of either party to exercise any right hereunder in any manner
impair the exercise of any such right.

      3.4 Construction. The headings herein are for convenience only, do not
constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof. This Agreement shall be construed as if drafted
jointly by the parties, and no presumption or burden of proof shall arise
favoring or disfavoring any party by virtue of the authorship of any provisions
of this Agreement.

      3.5 Successors and Assigns. This Agreement shall be binding upon and inure
to the benefit of the parties and their successors and permitted assigns. The
Company may not assign this Agreement or any rights or obligations hereunder
without the prior written consent of the Warrant Holders. Any Warrant Holder may
assign any or all of its rights under this Agreement to any Person to whom such
Warrant Holder assigns or transfers any Subject Warrants, provided such

Subject Warrants, by the provisions hereof that apply to the "Warrant Holders."

                                       3
<PAGE>

      3.6 No Third-Party Beneficiaries. This Agreement is intended for the
benefit of the parties hereto and their respective successors and permitted
assigns and is not for the benefit of, nor may any provision hereof be enforced
by, any other person.

      3.7 Governing Law. All questions concerning the construction, validity,
enforcement and interpretation of this Agreement shall be governed by and
construed and enforced in accordance with the internal laws of the State of New
York, without regard to the principles of conflicts of law thereof. Each party
agrees that all Proceedings concerning the interpretations, enforcement and
defense of the transactions contemplated by this Agreement may be commenced
exclusively in the state and federal courts sitting in the City of New York,
Borough of Manhattan (the "New York Courts"). Each party hereto hereby
irrevocably submits to the exclusive jurisdiction of the New York Courts for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any proceeding, any claim that it is not
personally subject to the jurisdiction of any such New York Court, or that such
proceeding has been commenced in an improper or inconvenient forum. Each party
hereto hereby irrevocably waives personal service of process and consents to
process being served in any such proceeding by mailing a copy thereof via
registered or certified mail or overnight delivery (with evidence of delivery)
to such party at the address in effect for notices to it under this Agreement
and agrees that such service shall constitute good and sufficient service of
process and notice thereof. Nothing contained herein shall be deemed to limit in
any way any right to serve process in any manner permitted by law. Each party
hereto hereby irrevocably waives, to the fullest extent permitted by applicable
law, any and all right to trial by jury in any legal proceeding arising out of
or relating to this Agreement or the transactions contemplated hereby.

      3.8 Survival. The representations, warranties, agreements and covenants
contained herein shall survive the Discount Exercise Period and the delivery of
the Warrant Shares.

      3.9 Execution. This Agreement may be executed in two or more counterparts,
all of which when taken together shall be considered one and the same agreement
and shall become effective when counterparts have been signed by each party and
delivered to the other party, it being understood that both parties need not
sign the same counterpart. In the event that any signature is delivered by
facsimile transmission, such signature shall create a valid and binding
obligation of the party executing (or on whose behalf such signature is
executed) with the same force and effect as if such facsimile signature page
were an original thereof.

      3.10 Severability. If any provision of this Agreement is held to be
invalid or unenforceable in any respect, the validity and enforceability of the
remaining terms and provisions of this Agreement shall not in any way be
affected or impaired thereby and the parties will attempt to agree upon a valid
and enforceable provision that is a reasonable substitute therefor, and upon so
agreeing, shall incorporate such substitute provision in this Agreement.

      3.11 Remedies. In addition to being entitled to exercise all rights
provided herein or granted by law, including recovery of damages, each of the
Warrant Holders and the Company will be entitled to specific performance under
this Agreement. The parties agree that monetary damages may not be adequate
compensation for any loss incurred by reason of any breach of

                                       4
<PAGE>

obligations described in the foregoing sentence and hereby agrees to waive in
any action for specific performance of any such obligation the defense that a
remedy at law would be adequate.

      3.12 Independent Nature of Warrant Holders' Obligations and Rights. The
obligations of each Warrant Holder under this Agreement are several and not
joint with the obligations of any other Warrant Holder, and no Warrant Holder
shall be responsible in any way for the performance of the obligations of any
other Warrant Holder under this Agreement. The decision of each Warrant Holder
to enter into this Agreement has been made by such Warrant Holder independently
of any other Warrant Holder. Nothing contained herein, and no action taken by
any Warrant Holder pursuant hereto, shall be deemed to constitute the Warrant
Holders as a partnership, an association, a joint venture or any other kind of
entity, or create a presumption that the Warrant Holders are in any way acting
in concert or as a group with respect to such obligations or the transactions
contemplated by this Agreement. Each Warrant Holder acknowledges that no other
Warrant Holder has acted as agent for such Warrant Holder in connection with
making entering into this Agreement and that no Warrant Holder will be acting as
agent of such Warrant Holder in connection with monitoring its investment in the
Warrant Shares or enforcing its rights under this Agreement. Each Warrant Holder
shall be entitled to independently protect and enforce its rights under this
Agreement, and it shall not be necessary for any other Warrant Holder to be
joined as an additional party in any proceeding for such purpose.

      3.13 Acknowledgement and Waiver. Each Warrant Holder (i) understands that
there may exist material non-public information concerning the business, affairs
or financial condition of the Company that has not been made available to such
Warrant Holder or disclosed to such Warrant Holder by the Company, and that the
Company has made no representations to such Warrant Holder concerning the
Company or its business, affairs, financial condition or plans or proposals,
(ii) has determined to enter into this Agreement even though such Warrant Holder
does not have any such information described in clause (i) above, having made
its own investment decision and not relying on the absence of any such
information or any such representation from the Company, and (iii) waives any
claims it may have or may hereafter possess against the Company for failure to
disclose to such Warrant Holder any such material non-public information. Each
Warrant Holder (i) understands that the Company is relying on the truth of such
Warrant Holder's representations and agreements set forth in this Section 3.13
in agreeing to enter into this Agreement and (ii) irrevocably authorizes the
Company to produce this letter or a copy hereof to any interested party in any
administrative or legal proceeding or official inquiry with respect to the
matters covered hereby.

      3.14 Affect on Warrants. Each Warrant Holder acknowledges that the
Company's waiver of $0.50 of the exercise price of the Warrants contemplated
hereby shall be effective only during the Discount Exercise Period. Such
agreement by the Company to temporarily waive a portion of the exercise price
shall not constitute an amendment to the Warrant and shall not otherwise have
any affect upon the terms of the Warrants. The Company reserves all of its
rights under the Warrant, including the right to waive a portion of the exercise
price of the Warrants, or to otherwise reduce the exercise price of the
Warrants, at any time and from time to time in the future, with respect to some
or all of the Warrants.

the Initial Purchaser (the "Private Exchange Notes" and "Private Exchange
Guarantees," respectively). If the Company fails to satisfy its obligations
under the Notes Registration Rights Agreement, it will be required to pay
additional interest to the holders of the Notes under certain circumstances in
accordance with the terms of the Notes Registration Rights Agreement.

      Holders of the Offered Shares (including Subsequent Purchasers) will have

applicable, except that the enforcement thereof may be subject to (i)
bankruptcy, insolvency, reorganization, receivership, moratorium, fraudulent

the Company has made, directly or indirectly, any payment or promise to pay, or
gift or promise to give, or authorized such a promise or gift, of any money or
anything of value, directly or indirectly, to (i) any foreign official (as such
term is defined in the United States Foreign Corrupt Practices Act of 1977 (as
amended, the "FCPA")) for the purpose of influencing any official act or
decision of such official or inducing him or her to use his or her influence to
affect any act or decision of a governmental authority, or (ii) any foreign
political party or official thereof or candidate for foreign political office
for the purpose of influencing any official act or decision of such party,

authority, in the case of both (i) and (ii) above, in order to assist the
Company to obtain or retain business for, or direct business, and under
circumstances which would subject the Company to liability under the FCPA or any
corresponding foreign laws. The Company has not made any bribe, rebate, payoff,
influence payment, kickback or other unlawful payment of funds or received or
retained any funds in violation of any law, rule or regulation.

      (v) Neither the execution, delivery or performance of the Documents nor
the consummation of any transactions contemplated therein will conflict with,
violate, constitute a breach of or a default (with the passage of time or
otherwise) under, require the consent of any person (other than (i) consents
already obtained and in full force and effect, (ii) governmental and regulatory
approvals required to consummate the Acquisition or (iii) as of the date hereof,
governmental and regulatory approvals that are necessary for Dune and the
Guarantors to incur the Indebtedness evidenced by the Notes and Guarantees,
issuance of the Offered Shares, and to grant Liens on the Collateral) under,
result in the imposition of a Lien on any assets of the Company or the
Guarantors (except for Liens created pursuant to the Documents), or result in an
acceleration of indebtedness under or pursuant to (1) the Charter Documents, (2)
any material Applicable Agreement, or (3) any Applicable Law. After consummation
of the Offering and the transactions contemplated in the Documents, no Default
or Event of Default under the Indenture will exist.

      (w) When executed and delivered, the Documents will conform in all
material respects to the descriptions thereof in the Time of Sale Circulars, as
the case may be.

      (x) No consent, approval, authorization or order of any Governmental
Authority or third party is required for the issuance and sale by Dune of the
Notes or the Offered Shares to the Initial Purchaser or the consummation by Dune
and the Guarantors of the other transactions contemplated hereby, except such as
have been obtained (and are in full force and effect) and such as may be
required under state securities or "Blue Sky" laws in connection with the
purchase and resale of the Notes or the Offered Shares by such Initial
Purchaser.

      (y) There is no action, claim, suit, demand, hearing, notice of violation
or deficiency, or proceeding, domestic or foreign (collectively, "Proceedings"),
pending or, to the knowledge of the Company or the Guarantors, threatened, that
either (i) seeks to restrain, enjoin, prevent the consummation of, or otherwise
challenge any of the Documents or any of the transactions contemplated therein,
or (ii) except as, would, individually or in the aggregate, have a Material
Adverse Effect. Except as disclosed in the Time of Sale Circulars, neither the

                                       10
<PAGE>

Company, nor the Guarantors are subject to any judgment, order, decree, rule or
regulation of any Governmental Authority that would reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect. No
injunction or order has been issued and no Proceeding is pending or, to the
knowledge of the Company or the Guarantors, threatened that (i) asserts that the
offer, sale and delivery of the Notes or the Offered Shares to the Initial
Purchaser pursuant to this Agreement or the initial resale of the Notes or the
Offered Shares by such Initial Purchaser in the manner contemplated by this
Agreement is subject to the registration requirements of the Act, or (ii) would
prevent or suspend the issuance or sale of the Notes or the Offered Shares,
including the Exempt Resales, or the use of the Preliminary Offering Circulars,
the Time of Sale Circulars, the Final Offering Circulars, or any amendments or
supplements thereto, in any jurisdiction.

      (z) Each of the Company and the Guarantors possesses all licenses,
permits, certificates, consents, orders, approvals and other authorizations
from, and has made all declarations and filings with, all Governmental
Authorities, presently required or necessary to own or lease, as the case may
be, and to operate their respective properties and to carry on their respective
businesses as now or proposed to be conducted as set forth in the Preliminary
Offering Circulars ("Permits"), except where the failure to obtain such Permits
would not reasonably be expected, individually or in the aggregate, to have a
Material Adverse Effect; each of the Company and the Guarantors has fulfilled
and performed all of its material obligations with respect to such Permits and
no event has occurred which allows, or after notice or lapse of time would
allow, revocation or termination thereof or results in any other material
impairment of the rights of the holder of any such Permit; and the neither the
Company nor the Guarantors have received any notice of any proceeding relating
to revocation or modification of any such Permit, except as disclosed in the
Time of Sale Circulars or the Final Offering Circulars or except where such
revocation or modification would not, individually or in the aggregate, have a
Material Adverse Effect.

      (aa) Each of the Company and the Guarantors has good and marketable title
to all real property owned by it and good title to all personal property owned
by it and good and indefeasible title to all leasehold estates in real and
personal property being leased by it and, as of the First Closing Date and, with
respect to the Optional Additional Shares, each Option Closing Date, will be
free and clear of all Liens (other than Permitted Liens). The assets of the
Company and the Guarantors include all of the assets and properties necessary or
required in, or otherwise material to, the conduct of the businesses of each of
them as currently conducted (as described in the Final Offering Circulars and
the Time of Sale Circulars), and such assets are in good working condition,
except where the failure of such assets to be in working condition would not,
individually or in the aggregate, have a Material Adverse Effect.

      (bb) Each of the Company and the Guarantors has good and defensible title
to its respective interests in its license and subsoil use contract relating to
the exploration, development and production on their respective oil fields, free
and clear of any Liens, except for those (i) created pursuant to their sub-soil
use contracts or operating agreements, unitization and pooling arrangements and
oil, condensate and gas sales contracts that secure payment of amounts not yet
due and payable and which are of a nature and scope customary in similar oil,
condensate and gas drilling and producing operations, (ii) described in the Time
of Sale Circulars and Final Offering Circulars or (ii) which neither
individually or in the aggregate would have a Material Adverse Effect. Except to
the extent described in the Time of Sale Circulars or Final Offering Circulars,
the licenses, subsoil use contracts or other arrangements held by each of the
Company and the Guarantors to explore, develop and exploit the oil fields, and
the manner in which the Company or the Guarantors acquired or otherwise procured
such licenses, subsoil use contracts or other arrangements, was generally
consistent with standard industry practices for acquiring or procuring rights to
explore, develop and exploit acreage for hydrocarbons. Each of the Company and
the Guarantors has complied in all respects with the terms of the licenses,
subsoil use contracts or other arrangements relating to the oil fields in which

                                       11
<PAGE>

each purports to own an interest, and no claim has been asserted by any person
or entity adverse to the rights of the Company or the Guarantors under any of
such licenses, subsoil use contracts or other arrangements or questioning its
rights to the continued use of the oil fields under any such licenses, subsoil
use contracts or other arrangements except for such noncompliance or claims as
would not individually or in the aggregate have a Material Adverse Effect. The
licenses, subsoil use contracts or other arrangements relating to the
exploration, development and production on the oil fields held by the Company
and the Guarantors are valid, existing and enforceable with such exceptions as
are described in the Time of Sale Circulars or Final Offering Circulars or which
in the aggregate would not have a Material Adverse Effect. Except as disclosed
in the Time of Sale Circulars or the Final Offering Circulars, the Company and
the Guarantors have the right to use or enjoy the benefits of the oil fields as
are necessary to their respective operations as now conducted.

      (cc) All Tax returns required to be filed by the Company and the
Guarantors have been filed, or valid extensions have been granted, and all such
returns that have been filed are true, complete, and correct in all material
respects. Except as disclosed in the Offering Circular, all material Taxes that
are due from the Company and the Guarantors have been paid other than those (i)
currently payable without penalty or interest or (ii) being contested in good
faith and by appropriate proceedings and for which adequate reserves have been
established in accordance with generally accepted accounting principles of the
United States, consistently applied ("GAAP"). Except as disclosed in the
Offering Circular, there are no actual or proposed Tax assessments against the
Company or the Guarantors that would, individually or in the aggregate, have a
Material Adverse Effect. The accruals and reserves on the books and records of
the Company and the Guarantors in respect of any material Tax liability for any
taxable period not finally determined are adequate to meet any assessments of
Tax for any such period. For purposes of this Agreement, the term "Tax" and
"Taxes" shall mean all Federal, state, local and foreign taxes, and other
assessments of a similar nature (whether imposed directly or through
withholding), including, without limitation, any interest, additions to tax, or
penalties applicable thereto.

      (dd) Each of the Company and the Guarantors owns, or is licensed under,
and has the right to use, all patents, patent rights, licenses, inventions,
copyrights, know-how (including, without limitation, trade secrets and other
unpatented and/or unpatentable proprietary or confidential information, systems
or procedures), trademarks, service marks and trade names (collectively,
"Intellectual Property") necessary for the conduct of its businesses and, as of
the First Closing Date and, with respect to the Optional Additional Shares, each
Option Closing Date, will be free and clear of all Liens, other than Permitted
Liens. Neither the Company nor the Guarantors have received any claims or
notices of any potential claim asserted by any person challenging the use of any
such Intellectual Property by the Company or the Guarantors or questioning the
validity or effectiveness of the Intellectual Property or any license or
agreement related thereto and neither the Company nor the Guarantors have any
knowledge of any facts or circumstances that would reasonably be expected to
result in any such claim or potential claim. To the knowledge of the Company,
there is no valid basis for any such claim, other than any claims that would
not, individually or in the aggregate, have a Material Adverse Effect. The
Company and the Guarantors have no reason to believe that the use of such
Intellectual Property by the Company or the Guarantors will infringe on the
Intellectual Property rights of any other person.

      (ee) The Company maintains a system of internal accounting controls over
financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange
Act) that complies with the Exchange Act and that is sufficient to provide
reasonable assurance that (i) material transactions are executed in accordance
with management's general or specific authorization, (ii) material transactions
are recorded as necessary to permit preparation of financial statements in
conformity with GAAP, and to maintain asset accountability, (iii) access to
assets is permitted only in accordance with management's general or specific
authorization and (iv) the recorded accountability for assets is compared with
the existing assets at reasonable intervals and appropriate action is taken with
respect to any material differences.

                                       12
<PAGE>

      (ff) Since the date of the latest audited financial statements included in
the Time of Sale Circulars, there has been no change in the Company's internal
control over financial reporting that has materially affected, or is reasonably
likely to materially affect, the Company's internal control over financial
reporting.

      (gg) The Company maintains disclosure controls and procedures (as such
term is defined in Rule 13a-15(e) of the Exchange Act) that comply with the
requirements of the Exchange Act; such disclosure controls and procedures have
been designed to ensure that material information relating to the Company and
its subsidiaries is made known to the Company's principal executive officer and
principal financial executive officer by others within those entities; and such
disclosure controls and procedures are effective.

      (hh) The audited consolidated financial statements and related notes of
the Company and the Guarantors contained in the Time of Sale Circulars and the
Final Offering Circulars (the "Financial Statements") present fairly the
financial position, results of operations and cash flows of Dune and its
consolidated Subsidiaries and the Goldking Entities, as of the respective dates
and for the respective periods to which they apply and have been prepared in
accordance with GAAP and the requirements of Regulation S-X of the Act. The
financial data set forth under "Summary Historical and Pro Forma Consolidated
Financial Information" and "Summary Reserve and Operating Data" included in the
Time of Sale Circulars and the Final Offering Circulars have been prepared on a
basis consistent with that of the Financial Statements and present fairly the
financial position and results of operations of Dune, the Guarantors and the
Goldking Entities consolidated, as applicable, as of the respective dates and
for the respective periods indicated. All other financial, statistical, and
market and industry-related data included in the Time of Sale Circulars and the
Final Offering Circulars are fairly and accurately presented and are based on or
derived from sources that Dune believes to be reliable and accurate.

      (ii) The pro forma financial information and the related notes of the
Company set forth in the Time of Sale Circulars and the Final Offering Circulars
include assumptions that were made in good faith and provide a reasonable basis
for presenting the significant effects directly attributable to the transactions
and events described therein. The related pro forma adjustments give appropriate
effect to those assumptions and the pro forma adjustments reflect the proper
application of those adjustments and the pro forma adjustments reflect the
proper application of those adjustments to the historical financial statement
amounts in the pro forma financial data included in the Time of Sale Circulars
and the Final Offering Circulars. The pro forma financial data set forth under
"Summary Historical and Pro Forma Consolidated Financial Information,"
"Unaudited Pro Forma Condensed Consolidated Financial Information" and "Pro
Forma Supplemental Oil and Natural Gas Disclosures" in the Time of Sale
Circulars and the Final Offering Circulars comply as to form in all material
respects with the applicable accounting requirements of Regulation S-X under the
Act and the pro forma adjustments have been properly applied to the historical
amounts in the compilation of those statements.

      (jj) Subsequent to the respective dates as of which information is given
in the Time of Sale Circulars and the Final Offering Circulars, except as
disclosed in the Time of Sale Circulars or the Final Offering Circulars, (i)
neither the Company nor the Guarantors have incurred any liabilities, direct or
contingent, that are material, individually or in the aggregate, to the Company
and the Guarantors, taken as a whole, or has entered into any transactions not
in the ordinary course of business and (ii) there has not been any material
decrease in the Capital Stock, shares or options issued pursuant to equity
incentive plans or purchase plans approved by the Company's Board of Directors
and repurchases of shares or options pursuant to repurchase plans already
approved by the Company's Board of Directors or any material increase in

                                       13
<PAGE>

long-term indebtedness or any material increase in short-term indebtedness of
the Company and the Guarantors, or any payment of or declaration to pay any
dividends or any other distribution with respect to the Company. There has not
been any material adverse change in the properties, business, prospects,
operations, earnings, assets, liabilities or condition (financial or otherwise)
of, the Company and the Guarantors (each of clauses (i) and (ii) in the
immediately preceding sentence and the events in this sentence, a "Material
Adverse Change"), since December 31, 2006. There is no event that is reasonably
likely to occur, which if it were to occur, would, individually or in the
aggregate, have a Material Adverse Effect, except such events that have been
adequately disclosed in the Time of Sale Circulars or the Final Offering
Circulars.

      (kk) No "nationally recognized statistical rating organization" (as such
term is defined for purposes of Rule 436(g)(2) under the Act) (i) has imposed
(or has informed the Company that it is considering imposing) any condition
(financial or otherwise) on the Company relating to any rating assigned to the
Company or the Guarantors or to any securities of the Company or the Guarantors,
or (ii) has indicated to the Company that it is considering (A) the downgrading,
suspension, or withdrawal of, or any review for a possible change that does not
indicate the direction of the possible change in, any rating so assigned, or (B)
any change in the outlook for any rating of the Company or the Guarantors or any
securities of the Company or the Guarantors.

      (ll) On the First Closing Date and, with respect to the Optional
Additional Shares, each Option Closing Date, each of the Company and the
Guarantors (i) will be solvent, (ii) will have sufficient capital with which to
conduct the business it is presently conducting and presently anticipates
conducting and (iii) will be able to pay its debts as they mature.

      (mm) Dune shall use the proceeds of the Offerings in the manner described
in the Time of Sale Circulars and the Final Offering Circulars under the caption
"Use of Proceeds."

      (nn) Except as disclosed in the Time of Sale Circulars or the Final
Offering Circulars and as it relates to the Initial Purchaser, neither Company
nor any affiliate (as defined in Rule 501(b)) has not and, to its knowledge
after due inquiry, no one acting on its behalf has, (i) taken, directly or
indirectly, any action designed to cause or to result in, or that has
constituted or which might reasonably be expected to constitute, the
stabilization or manipulation of the price of any security of the Company to
facilitate the sale or resale of any of the Notes or the Offered Shares, (ii)
sold, bid for, purchased, or paid anyone any compensation for soliciting
purchases of, any of the Notes or the Offered Shares, or (iii) except as
disclosed in the Time of Sale Circulars or the Final Offering Circulars, paid or
agreed to pay to any person any compensation for soliciting another to purchase
any other securities of the Company.

      (oo) Without limiting any provision herein, no registration under the Act
and no qualification of the Indenture under the TIA is required for the sale of
the Notes or the Offered Shares to the Initial Purchaser as contemplated hereby
or for the Exempt Resales, assuming (i) that the purchasers in the Exempt
Resales are QIBs or Accredited Investors or non-U.S. persons and (ii) the
accuracy of such Initial Purchaser's representations contained herein regarding
the absence of general solicitation in connection with the sale of the Notes or
the Offered Shares to the Initial Purchaser and in the Exempt Resales.

      (pp) The Notes and the Offered Shares are eligible for resale pursuant to
Rule 144A under the Act and no other securities of Dune are of the same class
(within the meaning of Rule 144A under the Act) as the Notes or the Offered
Shares and listed on a national securities exchange registered under Section 6
of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or
quoted in a U.S. automated inter-dealer quotation system. No securities of Dune
of the same class as the Notes or the Offered Shares have been offered, issued
or sold by Dune or any of its Affiliates within the six-month period immediately
prior to the date hereof.

                                       14
<PAGE>

      (qq) Dune is subject to the reporting requirements of the Exchange Act and
is eligible to register resales of the Offered Shares and the Underlying
Securities on a registration statement on Form S-3 under the Act. There exist no
facts or circumstances (including without limitation any required approvals or
waivers or any circumstances that may delay or prevent the obtaining of
accountant's consents) that reasonably would be expected to prohibit or delay
the preparation and filing of a registration statement on Form S-3 that will be
available to register resales of the Offered Shares or the Underlying Securities
under the Act.

      (rr) Neither Dune nor any of its Affiliates or other persons acting on
behalf of the Company has offered or sold the Notes or the Offered Shares by
means of any general solicitation or general advertising within the meaning of
Rule 502(c) under the Act or, with respect to Notes sold outside the United
States to non-U.S. persons (as defined in Rule 902 under the Act), by means of
any directed selling efforts within the meaning of Rule 902 under the Act, and
Dune, each Affiliate of the Company and each other person acting on behalf of
the Company have complied with and will implement the "offering restrictions"
within the meaning of such Rule 902; provided, that no representation is made in
this subsection with respect to the actions of the Initial Purchaser.

      (ss) Each of the Company, the Guarantors, and each ERISA Affiliate has
fulfilled its obligations, if any, under the minimum funding standards of
Section 302 of the Employee Retirement Income Security Act of 1974, as amended
("ERISA") with respect to each "pension plan" (as defined in Section 3(2) of
ERISA), subject to Section 302 of ERISA which the Company, the Guarantors, or
any ERISA Affiliate sponsors or maintains, or with respect to which it has (or
within the last three years had) any obligation to make contributions, and each
such plan is in compliance in all material respects with the presently
applicable provisions of ERISA and the Code (as defined below). Neither the
Company or the Guarantors, nor any ERISA Affiliate thereof has incurred any
material unpaid liability to any plan which is subject to ERISA (other than for
the payment of premiums in the ordinary course). "ERISA Affiliate" means a
corporation, trade or business that is, along with the Company or the
Guarantors, a member of a controlled group of corporations or a controlled group
of trades or businesses, as described in Section 414 of the Internal Revenue
Code of 1986, as amended (the "Code") or Section 4001 of ERISA.

      (tt) (i) Except as disclosed in the Time of Sale Circulars or the Final
Offering Circulars, neither the Company nor the Guarantors are party to or bound
by any collective bargaining agreement with any labor organization; (ii) there
is no union representation question existing with respect to the employees of
the Company or the Guarantors, and, to the Company's knowledge, no union
organizing or decertification efforts are underway or threatened against the
Company or the Guarantors; (iii) no labor strike, work stoppage, slowdown, or
other material labor dispute is pending against the Company or the Guarantors,
or, to the knowledge of the Company or the Guarantors threatened against the
Company or the Guarantors; (iv) there is no worker's compensation liability,
experience or matter that could be reasonably expected to have a Material
Adverse Effect; (v) there is no threatened or pending liability against the
Company or the Guarantors pursuant to the Worker Adjustment Retraining and
Notification Act of 1988, as amended ("WARN"), or any similar state or local
law; (vi) there is no employment-related charge, complaint, grievance,
investigation, unfair labor practice claim, or inquiry of any kind, pending
against the Company or the Guarantors that could, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect; (vii) no
employee or agent of the Company or the Guarantors has committed any act or
omission giving rise to liability for any violation identified in subsection (v)
and (vi) above, other than such acts or omissions that would not, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect;
and (viii) no term or condition of employment exists through arbitration awards,
settlement agreements, or side agreements that is contrary to the express terms
of any applicable collective bargaining agreement.

                                       15
<PAGE>

      (uu) None of the transactions contemplated in the Documents or the
application by Dune or the Guarantors of the proceeds of the Notes or the
Offered Shares will violate or result in a violation of Section 7 of the
Exchange Act, (including, without limitation, Regulation T (12 C.F.R. Part 220),
Regulation U (12 C.F.R. Part 221) or Regulation X (12 C.F.R. Part 224) of the
Board of Governors of the Federal Reserve System).

      (vv) Neither Dune nor the Guarantors are an open-end investment company,
unit investment trust or face-amount certificate company that is or is required
to be registered under Section 8 of the Investment Company Act of 1940, as
amended (the "Investment Company Act"); and neither Dune nor the Guarantors are
or, after giving effect to the offering and sale of the Notes and the Offered
Shares and the application of the proceeds thereof as described in the Time of
Sale Circulars or the Final Offering Circulars, will be an "investment company"
as defined in the Investment Company Act.

      (ww) Dune has not engaged any broker, finder, commission agent or other
person (other than the Initial Purchaser) in connection with the Offering or any
of the transactions contemplated in the Documents, and Dune is not under any
obligation to pay any broker's fee or commission in connection with such
transactions (other than commissions or fees to the Initial Purchaser).

      (xx) Except as disclosed in the Time of Sale Circulars and the Final
Offering Circulars, each of the Company and the Guarantors (i) is in compliance
with all applicable foreign, Federal, state and local laws and regulations
relating to the protection of the environment or hazardous or toxic substances
of wastes, pollutants or contaminants ("Environmental Laws"), (ii) has received
and is in compliance with all permits, licenses or other approvals required of
it under applicable Environmental Laws to conduct their respective businesses
and (iii) has not received notice of any actual or potential liability for the
investigation or remediation of any disposal or release of hazardous or toxic
substances or wastes, pollutants or contaminants, in each case except where such
non-compliance with Environmental Laws, failure to receive and comply with
required permits, licenses or other approvals, or liability would not,
individually or in the aggregate, have a Material Adverse Effect, whether or not
arising from transactions in the ordinary course of business. Except as
disclosed in the Time of Sale Circulars or the Final Offering Circulars, neither
the Company nor the Guarantors have been named as a "potentially responsible
party" under the Comprehensive Environmental Response, Compensation, and
Liability Act of 1980, as amended.

      (yy) As of the First Closing Date and, with respect to the Optional
Additional Shares, each Option Closing Date other than as described in the Time
of Sale Circulars and the Final Offering Circulars, there will be no
encumbrances or restrictions on the ability of the Guarantors of the Company (x)
to pay dividends or make other distributions on the Guarantors' Capital Stock or
to pay any indebtedness to the Company or the Guarantors, (y) to make loans or
advances or pay any indebtedness to, or investments in, the Company or the
Guarantors or (z) to transfer any of its property or assets to the Company or
the Guarantors.

      (zz) Each certificate signed by any officer of the Company or the
Guarantors delivered to the Initial Purchaser shall be deemed a representation
and warranty by the Company or the Guarantors (and not individually by such
officer) to the Initial Purchaser with respect to the matters covered thereby.

      (aaa) Each of the Company and the Guarantors is insured by insurers of
recognized financial responsibility against such losses and risks and in such
amounts as are prudent and customary in the businesses in which they are
engaged. All policies of insurance insuring the Company or the Guarantors or
their respective businesses, assets, employees, officers and directors are in
full force and effect. The Company and the Guarantors are in compliance with the

                                       16
<PAGE>

terms of such policies and instruments in all material respects, and there are
no claims by the Company or the Guarantors under any such policy or instrument
as to which any insurance company is denying liability (or defending under a
reservation of rights clause). Neither the Company nor the Guarantors have been
refused any insurance coverage sought or applied for, and neither the Company
nor the Guarantors have any reason to believe that it will not be able to renew
its existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers as may be necessary to continue its
business at a cost that would not, individually or in the aggregate, reasonably
be expected to have a Material Adverse Effect.

      (bbb) As of the First Closing Date and, with respect to the Optional
Additional Shares, each Option Closing Date, except with respect to Permitted
Liens, there will be no currently effective financing statement, security
agreement, chattel mortgage, real estate mortgage or other document filed or
recorded with any filing records, registry, or other public office, that
purports to cover, affect or give notice of any present or possible future Lien
on, or security interest in, any assets or property of the Company or any
Domestic Restricted Subsidiary or any rights thereunder.

      (ccc) Malone & Bailey P.C. and Hein and Associates LLP, the accountants
who have audited the financial statements of Dune and Goldking, respectively,
included as part of the Time of Sale Circulars and the Final Offering Circulars,
are independent certified public accountants with respect to the Company, under
Rule 101 of the AICPA's code of professional conduct and its interpretations and
rulings, during the periods covered by the financial statements on which they
reported included in the Time of Sale Circulars.

      (ddd) The Company has all requisite corporate power and authority to
execute, deliver and perform its obligations under the Acquisition Agreement.
The Acquisition Agreement has been duly and validly authorized by the Company,
constitutes a legal, valid and binding obligation of the Company and is in full
force and effect. The representations and warranties contained in the
Acquisition Agreement are true as of the date made therein. The Acquisition
Agreement conforms in all material respects to the descriptions thereof in the
Time of Sale Circulars and the Final Offering Circulars.

      9. Indemnification and Contribution.

      (a) The Company and the Guarantors, jointly and severally, agree to
indemnify and hold harmless the Initial Purchaser, and each person, if any, who
controls such Initial Purchaser within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, against any losses, claims, damages or
liabilities of any kind to which, jointly or severally, such Initial Purchaser
or such controlling person may become subject under the Act, the Exchange Act or
otherwise, insofar as any such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon:

            (i) any untrue statement or alleged untrue statement of any material
      fact contained in the Time of Sale Circulars, any Offering Circulars or
      any amendment or supplement thereto or any Supplemental Offering
      Materials; or

            (ii) the omission or alleged omission to state, in the Time of Sale
      Circulars, any Offering Circulars or any amendment or supplement thereto
      or any Supplemental Offering Materials, a material fact required to be
      stated therein or necessary to make the statements therein, in light of
      the circumstances under which they were made, not misleading;

including any losses, claims, damages or liabilities arising out of or based
upon the Company's failure to perform its obligations under Sections 6(c) and
6(d), and, subject to the provisions hereof, will reimburse, as incurred, the
Initial Purchaser and each such controlling person for any legal or other
expenses reasonably incurred by such Initial Purchaser or such controlling
person in connection with investigating, defending against or appearing as a
third-party witness in connection with any such loss, claim, damage, liability
or action in respect thereof; provided, however, neither the Company nor the
Guarantors will be liable in any such case to the extent (but only to the
extent) that any such loss, claim, damage or liability is finally judicially
determined by a court of competent jurisdiction in a final, unappealable
judgment, to have resulted primarily from any untrue statement or alleged untrue
statement or omission or alleged omission made in any the Time of Sale
Circulars, any Offering Circulars or any amendment or supplement thereto or any
Supplemental Offering Materials in reliance upon and in conformity with the
Initial Purchaser Information. This indemnity agreement will be in addition to
any liability that the Company may otherwise have to the indemnified parties.

      (b) Each Initial Purchaser, severally and not jointly, agrees to indemnify
and hold harmless each of the Company, the Guarantors, and their respective
directors, officers and each person, if any, who controls the Company or the
Guarantors within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act against any losses, claims, damages or liabilities of any kind to
which the Company or any such director, officer or controlling person may become
subject under the Act, the Exchange Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) are finally
judicially determined by a court of competent jurisdiction in a final,

                                       27
<PAGE>

unappealable judgment, to have resulted primarily from (i) any untrue statement
or alleged untrue statement of any material fact contained in the Time of Sale
Circulars, any Offering Circulars or any amendment or supplement thereto or any
Supplemental Offering Materials or (ii) the omission or the alleged omission to
state therein a material fact required to be stated in the Timing of Sale
Circulars, any Offering Circulars or any amendment or supplement thereto or any
Supplemental Offering Materials or necessary to make the statements therein not
misleading, in each case to the extent (but only to the extent) that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with the Initial Purchaser Information; and,
subject to the limitation set forth immediately preceding this clause, will
reimburse, as incurred, any legal or other expenses incurred by the Company or
the Guarantors or any of their respective directors, officers or controlling
persons in connection with any such loss, claim, damage, liability or action in
respect thereof. This indemnity agreement will be in addition to any liability
that such Initial Purchaser may otherwise have to such indemnified parties.

      (c) As promptly as reasonably practical after receipt by an indemnified
party under this Section 9 of notice of the commencement of any action for which
such indemnified party is entitled to indemnification under this Section 9, such
indemnified party will, if a claim in respect thereof is to be made against the
indemnifying party under this Section 9, notify the indemnifying party of the
commencement thereof in writing; but the omission to so notify the indemnifying
party (i) will not relieve such indemnifying party from any liability under
paragraph (a) or (b) above unless and only to the extent it is materially
prejudiced as a result thereof and (ii) will not, in any event, relieve the
indemnifying party from any obligations to any indemnified party other than the
indemnification obligation provided in paragraphs (a) and (b) above. In case any
such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may determine,
jointly with any other indemnifying party similarly notified, to assume the
defense thereof, with counsel reasonably satisfactory to such indemnified party;
provided, however, that if (i) the use of counsel chosen by the indemnifying
party to represent the indemnified party would present such counsel with a
conflict of interest, (ii) the defendants in any such action include both the
indemnified party and the indemnifying party, and the indemnified party shall
have been advised by counsel in writing that there may be one or more legal
defenses available to it and/or other indemnified parties that are different
from or additional to those available to the indemnifying party, or (iii) the
indemnifying party shall not have employed counsel reasonably satisfactory to
the indemnified party to represent the indemnified party within a reasonable
time after receipt by the indemnifying party of notice of the institution of
such action, then, in each such case, the indemnifying party shall not have the
right to direct the defense of such action on behalf of such indemnified party
or parties and such indemnified party or parties shall have the right to select
separate counsel to defend such action on behalf of such indemnified party or
parties at the expense of the indemnifying party. After notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof and approval by such indemnified party of counsel appointed to
defend such action, the indemnifying party will not be liable to such
indemnified party under this Section 9 for any legal or other expenses, other
than reasonable costs of investigation, subsequently incurred by such
indemnified party in connection with the defense thereof, unless (i) the
indemnified party shall have employed separate counsel in accordance with the
proviso to the immediately preceding sentence (it being understood, however,
that in connection with such action the indemnifying party shall not be liable
for the expenses of more than one separate counsel (in addition to local
counsel) in any one action or separate but substantially similar actions in the
same jurisdiction arising out of the same general allegations or circumstances,
designated by the Initial Purchaser in the case of paragraph (a) of this Section
9 or the Company or the Guarantors in the case of paragraph (b) of this Section

                                       28
<PAGE>

9, representing the indemnified parties under such paragraph (a) or paragraph
(b), as the case may be, who are parties to such action or actions) or (ii) the
indemnifying party has authorized in writing the employment of counsel for the
indemnified party at the expense of the indemnifying party. After such notice
from the indemnifying party to such indemnified party, the indemnifying party
will not be liable for the costs and expenses of any settlement of such action
effected by such indemnified party without the prior written consent of the
indemnifying party (which consent shall not be unreasonably withheld,
conditioned or delayed), unless such indemnified party waived in writing its
rights under this Section 9, in which case the indemnified party may effect such
a settlement without such consent.

      (d) No indemnifying party shall be liable under this Section 9 for any
settlement of any claim or action (or threatened claim or action) effected
without its written consent, which shall not be unreasonably withheld,
conditioned or delayed, but if a claim or action is settled with its written
consent, or if there be a final judgment for the plaintiff with respect to any
such claim or action, each indemnifying party, jointly and severally, agrees,
subject to the exceptions and limitations set forth above, to indemnify and hold
harmless each indemnified party from and against any and all losses, claims,
damages or liabilities (and legal and other expenses as set forth above)
incurred by reason of such settlement or judgment. No indemnifying party shall,
without the prior written consent of the indemnified party (which consent shall
not be unreasonably withheld), effect any settlement or compromise of any
pending or threatened proceeding in respect of which the indemnified party is or
could have been a party, or indemnity could have been sought hereunder by the
indemnified party, unless such settlement (A) includes an unconditional written
release of the indemnified party, in form and substance satisfactory to the
indemnified party, from all liability on claims that are the subject matter of
such proceeding and (B) does not include any statement as to an admission of
fault, culpability or failure to act by or on behalf of the indemnified party.

      (e) In circumstances in which the indemnity agreement provided for in the
preceding paragraphs of this Section 9 is unavailable to, or insufficient to
hold harmless, an indemnified party in respect of any losses, claims, damages or
liabilities (or actions in respect thereof), each indemnifying party, in order
to provide for just and equitable contributions, shall contribute to the amount
paid or payable by such indemnified party as a result of such losses, claims,
damages or liabilities (or actions in respect thereof) in such proportion as is
appropriate to reflect (i) the relative benefits received by the indemnifying
party or parties, on the one hand, and the indemnified party, on the other, from
the Offering or (ii) if the allocation provided by the foregoing clause (i) is
not permitted by applicable law, not only such relative benefits but also the
relative fault of the indemnifying party or parties, on the one hand, and the
indemnified party, on the other, in connection with the statements or omissions
or alleged statements or omissions that resulted in such losses, claims, damages
or liabilities (or actions in respect thereof). The relative benefits received
by the Company or the Guarantors, on the one hand, and such Initial Purchaser,
on the other, shall be deemed to be in the same proportion as the net proceeds
from the Offering (before deducting expenses) received by the Company bear to
the total discounts, commissions and fees received by such Initial Purchaser.
The relative fault of the parties shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company or the Guarantors, on the one hand, or such
Initial Purchaser, on the other, the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission
or alleged statement or omissions, and any other equitable considerations
appropriate in the circumstances.

      (f) The Company, the Guarantors and the Initial Purchaser agree that it
would not be equitable if the amount of such contribution determined pursuant to
the immediately preceding paragraph (e) were determined by pro rata or per
capita allocation or by any other method of allocation that does not take into
account the equitable considerations referred to in the first sentence of the
immediately preceding paragraph (e). Notwithstanding any other provision of this
Section 9, the Initial Purchaser shall not be obligated to make contributions

                                       29
<PAGE>

hereunder that in the aggregate exceed the total discounts, commissions, fees
and other compensation received by such Initial Purchaser under this Agreement
less the aggregate amount of any damages that such Initial Purchaser has
otherwise been required to pay by reason of the untrue or alleged untrue
statements or the omissions or alleged omissions to state a material fact. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of the immediately
preceding paragraph (e), each person, if any, who controls the Initial Purchaser
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act
shall have the same rights to contribution as such Initial Purchaser, and each
director and officer of the Company or the Guarantors and each person, if any,
who controls the Company or the Guarantors within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act, shall have the same rights to
contribution as the Company and the Guarantors.

      10. Termination. The Initial Purchaser may terminate this Agreement at any
time on or prior to the First Closing Date and, with respect to the Optional
Additional Shares, each Option Closing Date by written notice to the Company if
any of the following has occurred:

      (a) since the date hereof, any Material Adverse Effect or development
involving or reasonably expected to result in a prospective Material Adverse
Effect that could, in such Initial Purchaser's reasonable judgment, be expected
to (i) make it impracticable or inadvisable to proceed with the offering or
delivery of the Notes or the Offered Shares on the terms and in the manner
contemplated in the Time of Sale Circulars or the Final Offering Circulars, or
(ii) materially impair the investment quality of any of the Notes;

      (b) the failure of the Company to satisfy the conditions contained in
Section 8 hereof on or prior to the First Closing Date and, with respect to the
Optional Additional Shares, each Option Closing Date;

      (c) any outbreak or escalation of hostilities or other national or
international calamity or crisis, including acts of terrorism, or material
adverse change or disruption in economic conditions in, or in the financial
markets of, the United States (it being understood that any such change or
disruption shall be relative to such conditions and markets as in effect on the
date hereof), if the effect of such outbreak, escalation, calamity, crisis, act
or material adverse change in the economic conditions in, or in the financial
markets of, the United States could be reasonably expected to make it, in such
Initial Purchaser's sole judgment, impracticable or inadvisable to market or
proceed with the offering or delivery of the Notes or the Offered Shares on the
terms and in the manner contemplated in Time of Sale Circulars or the Final
Offering Circulars or to enforce contracts for the sale of any of the Notes or
the Offered Shares;

      (d) the suspension or limitation of trading generally in securities on the
New York Stock Exchange, the American Stock Exchange or the NASDAQ National
Market or any setting of limitations on prices for securities on any such
exchange or NASDAQ National Market;

      (e) any securities of the Company shall have been downgraded or placed on
any "watch list" for possible downgrading by any "nationally recognized
statistical rating organization," as such term is defined for purposes of Rule
436(g)(2) under the Act; or

      (f) the declaration of a banking moratorium by any Governmental Authority;
or the taking of any action by any Governmental Authority after the date hereof
in respect of its monetary or fiscal affairs that in such Initial Purchaser's
opinion could reasonably be expected to have a material adverse effect on the
financial markets in the United States or elsewhere.

                                       30

      11. Survival of Representations and Indemnities. The respective
representations and warranties, covenants, indemnities and contribution and
expense reimbursement provisions and other agreements, of the Company and the
Guarantors set forth in or made pursuant to this Agreement shall remain
operative and in full force and effect, and will survive, regardless of (i) any
investigation, or statement as to the results thereof, made by or on behalf of
the Initial Purchaser, (ii) acceptance of the Notes or the Offered Shares, and
payment for them hereunder, and (iii) any termination of this Agreement.

      12. Information Supplied by the Initial Purchaser. The name of the Initial
Purchaser set forth on the front and back cover and under the heading "Plan of
Distribution" of the Preliminary Offering Circulars and the Final Offering
Circulars and the statements set forth in: (i) the seventh and eight full
paragraphs on pages 165 and 166 of the Notes Offering Circular and the fourth,
fifth and sixth full paragraphs on page 147 of the Offered Shares Final Offering
Circular regarding stabilization by such Initial Purchaser, (ii) the first and
second sentences of the third paragraph, the first, second, third, fourth and
sixth sentences of the ninth paragraph under the heading "Plan of Distribution"
in the Notes Offering Circular and the first, second, third, fourth and sixth
sentences of the tenth paragraph under the heading "Plan of Distribution" in the
Offered Shares Final Offering Circular (to the extent such statements relate to
such Initial Purchaser) (such statements as they relate to such Initial
Purchaser is referred to herein with respect to such Initial Purchaser as the
"Initial Purchaser Information") constitute the only information furnished by
such Initial Purchaser as to itself to the Company or the Guarantors for the
purposes of Sections 5(a) and 9 hereof.

      13. Miscellaneous.

      (a) The Company shall use its commercially reasonable best efforts to
cause to be delivered to the Collateral Agent, no later than 30 days after the
First Closing Date and, with respect to the Optional Additional Shares, each
Option Closing Date and at the Company's sole cost and expense, a lender's title
insurance policy issued by a nationally recognized title insurance company in an
insured amount reasonably satisfactory to the Collateral Agent and insuring the
Deed of Trust as a valid and enforceable first priority deed of trust lien on
the real and personal property relating to the Obligors' facilities in the
locations to be listed on Schedule I to the Indenture, free and clear of all
defects and encumbrances except Permitted Encumbrances (as defined in the Deed
of Trust), together with such endorsements, affirmative coverage, coinsurance
and reinsurance which Collateral Agent may reasonably request.

      (b) Notices given pursuant to any provision of this Agreement shall be
addressed as follows: (i) if to the Company, to: Dune Energy, Inc., 3050 Post
Oak Boulevard, Suite 695 Houston, Texas, 77056, with a copy to: Eaton & Van
Winkle LLP, 3 Park Avenue, 16th Floor, New York, NY 10016, Attention: Matthew S.
Cohen, Esq. and (ii) if to the Initial Purchaser, to: Jefferies & Company, Inc.,

      (c) This Agreement has been and is made solely for the benefit of and
shall be binding upon the Company, the Initial Purchaser and, to the extent
provided in Section 9 hereof, the controlling persons, officers, directors,
partners, employees, representatives and agents referred to in Section 9, and
their respective heirs, executors, administrators, successors and assigns, all
as and to the extent provided in this Agreement, and no other person shall
acquire or have any right under or by virtue of this Agreement. The term
"successors and assigns" shall not include a purchaser of any of the Notes or
the Offered Shares from an Initial Purchaser merely because of such purchase.
Notwithstanding the foregoing, it is expressly understood and agreed that each
purchaser who purchases Notes or Offered Shares from an Initial Purchaser is
intended to be a beneficiary of the Company's covenants contained in the
Registration Rights Agreement to the same extent as if the Notes or the Offered
Shares were sold and those covenants were made directly to such purchaser by the
Company, and each such purchaser shall have the right to take action against the
Company to enforce, and obtain damages for any breach of, those covenants.
