hereof which are either disclosed in the Prospectus or of which the Underwriters

              (i)  there shall not have occurred any downgrading, nor shall any
          notice have been given of any intended or potential downgrading or of
          any review for a possible change that does not indicate the direction
          of the possible change, in the rating accorded any of the Company's
          securities by any "nationally recognized statistical rating
          organization," as such term is defined for purposes of Rule 436(g)(2)
          under the Securities Act;

              (ii) there shall not have occurred any change, or any development

          North American Prospectuses (exclusive of any amendment or supplements
          thereto subsequent to the date of this Agreement) that, in your
          judgment, is material and adverse and that makes it, in your judgment,
          impracticable to market the Shares on the terms and in the manner
          contemplated in the Prospectus; and





   12

                                                                              11

              (iii) there shall not have developed, occurred, or come into
          effect, any occurrence of national or international consequence or any
          action, governmental regulation, inquiry or other occurrence of any
          nature whatsoever which, in the opinion of the Underwriters, seriously
          effects or may seriously effect the Canadian financial markets or the
          business of the Company and its subsidiaries on a consolidated basis.

          (b) The Canadian Prospectus shall have been filed with the Canadian
     Commissions of each of the Qualifying Provinces in accordance with
     applicable Canadian Securities Laws and receipts therefore shall have been
     issued by such Canadian Commissions.

          (c) You shall have received on the Closing Date a certificate, dated
     the Closing Date and signed by an executive officer of the Company, to the
     effect set forth in clause (a)(i) above and to the effect that the

     complied with all of the agreements and satisfied all of the conditions on
     its part to be performed or satisfied hereunder on or before the Closing
     Date.

          The officer signing and delivering such certificate may rely upon the
     best of his knowledge as to proceedings threatened.

          existing in good standing under the laws of the jurisdiction of its

          (d) If, during such period after the first date of the public offering
     of the Shares as in the opinion of your counsel the Prospectus is required
     by law to be delivered in connection with sales by an Underwriter or
     dealer, any event shall occur or condition exist as a result of which it is
     necessary to amend or supplement the Prospectus in order to make the
     statements therein, in the light of the circumstances when the Prospectus
     is delivered to a purchaser, not misleading, or if, in the opinion of your
     counsel, it is necessary to amend or supplement the Prospectus to comply
     with applicable law, forthwith to prepare, file with the Commission and
     furnish, at its own expense, to the Underwriters and to the dealers (whose
     names and addresses you will furnish to the Company) to which Shares may

     a purchaser, be misleading or so that the Prospectus, as amended or
     supplemented, will comply with law.

          (e) If at any time after the date of the Canadian Prospectus: (i) any
     material change (actual,




   21

     business, affairs, operations, assets, liabilities (contingent or
     otherwise) or capital of the Company and its subsidiaries, taken as a
     whole, shall have occurred; (ii) any material fact has arisen or is
     discovered which would have been required to have been stated in the Final
     Canadian Prospectus had it arisen or been discovered on or prior to the
     date of the Final Canadian Prospectus; or (iii) any change in any material
     fact contained in the Final Canadian Prospectus or any amendments or
     supplements thereto arises or is discovered, which change is, or could
     reasonably be expected to be, of such a nature as to render any statement
     in the Canadian Prospectus or any amendments or supplements thereto
     misleading or untrue or which would result in a misrepresentation in the
     Canadian Prospectus or any amendments or supplements thereto or which would
     result in the Canadian Prospectus or any amendments or supplements thereto
     not complying (to the extent that such compliance is required) with
     Canadian Securities Laws, then the Company shall promptly, and in any event
     within any applicable time limitation, comply, to the satisfaction of the

     a result of such fact or change. Notwithstanding the foregoing, the Company
     shall not file any amendments or supplements to the Canadian Prospectus to
     which the Underwriters and the Canadian Affiliates, acting reasonably,
     object. The Company shall, in good faith, discuss with the Underwriters and
     the Canadian Affiliates any fact or change in circumstances (actual,
     anticipated, contemplated or threatened, financial or otherwise) which is
     of such a nature that there is reasonable doubt as to whether any action
     need be taken pursuant to the operation of this paragraph.

     securities or Blue Sky laws of such jurisdictions as you shall reasonably

     Commission thereunder.

          7. Expenses. Whether or not the transactions contemplated in this
Agreement are consummated or this Agreement is terminated, the Company agrees to
pay or cause to be paid all expenses incident to the performance of its

disbursements of their counsel, stock transfer taxes payable on resale of any of
the Shares by them and any advertising expenses connected with any offers they
may make.

          The provisions of this Section 7 shall not affect any agreement that
the Sellers may otherwise have for the allocation of such expenses among
themselves.

          8. Indemnity and Contribution. (a) The Company agrees to indemnify and
hold harmless each Underwriter (including its respective Canadian Affiliate) and
each person, if any, who controls any Underwriter within the meaning of either
Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), from and against any and all losses,
claims, damages and liabilities (including, without limitation, any legal or
other expenses reasonably incurred by any Underwriter or any such controlling
person in connection with defending or investigating any such action or claim)
caused by any untrue statement or alleged untrue statement of a material fact
contained in any Offering Document, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages or liabilities are caused by any such untrue statement
or omission or alleged untrue statement or omission based upon information
relating to any Underwriter furnished to the Company in writing by such
Underwriter through you expressly for use therein.

          (b) Each Underwriter agrees, severally and not jointly, to indemnify
and hold harmless the Company, its directors, its officers who sign the
Registration Statement and each person, if any, who controls the Company within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act to the same extent as the foregoing indemnity from the Company to
such Underwriter, but only with reference to information relating to such
Underwriter furnished to the Company in writing by such Underwriter through you
expressly for use in any Offering Document.

          (c) In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to either of the two preceding paragraphs, such person (the
"indemnified party") shall promptly notify the person against whom such
indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party,




   24

                                                                              23

upon request of the indemnified party, shall retain counsel reasonably
satisfactory to the indemnified party to represent the indemnified party and any
others the indemnifying party may designate in such proceeding and shall pay the
fees and disbursements of such counsel related to such proceeding. In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the indemnifying party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for (a) the fees and expenses of more than one separate firm (in
addition to any local counsel) for all Underwriters and all persons, if any, who
control any Underwriter within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act and (b) the fees and expenses
of more than one separate firm (in addition to any local counsel) for the
Company, its directors, its officers who sign the Registration Statement and
each person, if any, who controls the Company within the meaning of either such
Section. In the case of any such separate firm for the Underwriters and such
control persons of Underwriters, such firm shall be designated in writing by
Morgan Stanley & Co. Incorporated. In the case of any such separate firm for the
Company, and such directors, officers and control persons of the Company, such
firm shall be designated in writing by the Company. The indemnifying party shall
not be liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the indemnifying party agrees to indemnify each indemnified party
from and against any loss or liability by reason of such settlement or judgment.
Notwithstanding the foregoing sentence, if at any time an indemnified party
shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel as contemplated by the second and third
sentences of this paragraph, the indemnifying party agrees that it shall be
liable for any settlement of any proceeding effected without its written consent
if (i) such settlement is entered into more than 30 days after receipt by such
indemnifying party of the aforesaid request and (ii) such




   25

                                                                              24

indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

          (d) To the extent the indemnification provided for in Section 8(a) or
8(b) is unavailable to an indemnified party or insufficient in respect of any
losses, claims, damages or liabilities referred to therein, then each
indemnifying party under such subsection, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the indemnifying party or parties on the one hand and the
indemnified party or parties on the other hand from the offering of the Shares
or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the indemnifying party or parties on the one hand and of the indemnified party
or parties on the other hand in connection with the statements or omissions that
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations. The relative benefits received by the Company
on the one hand and the Underwriters on the other hand in connection with the
offering of the Shares shall be deemed to be in the same respective proportions
as the net proceeds from the offering of the Shares (before deducting expenses)
received by the Company and the total underwriting discounts and commissions
received by the Underwriters, in each case as set forth in the table on the
cover of the Prospectus, bear to the aggregate public offering price of the
Shares. The relative fault of the Company on the one hand and the Underwriters
on the other hand 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 by the Underwriters and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The




   26

                                                                              25

Underwriters' respective obligations to contribute pursuant to this Section 8
are several in proportion to the respective number of shares they have purchased
hereunder, and not joint.

          (e) The Company and the Underwriters agree that it would not be just
or equitable if contribution pursuant to this Section 8 were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such indemnified party
in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 8, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Shares underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages that such Underwriter
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The remedies provided for in this Section 8 are
not exclusive and shall not limit any rights or remedies which may otherwise be
available to any indemnified party at law or in equity.

          (f) The indemnity and contribution provisions contained in this
Section 8 and the representations and warranties of the Company contained in
this Agreement shall remain operative and in full force and effect regardless of
(i) any termination of this Agreement, (ii) any investigation made by or on
behalf of any Underwriter or any person controlling any Underwriter or by or on
behalf of the Company, its officers or directors or any person controlling the
Company and (iii) acceptance of and payment for any of the Shares.

          10. Termination. This Agreement shall be subject to termination by
notice given by you to the Company, if (a) after the execution and delivery of
this Agreement and prior to the Closing Date (i) trading generally shall have
been suspended or materially limited on or by, as the case may




   27

                                                                              26

be, any of the NYSE, the American Stock Exchange, the National Association of
Securities Dealers, Inc., the Chicago Board of Options Exchange, the Chicago
Mercantile Exchange, the Chicago Board of Trade or the TSE, (ii) trading of any
securities of the Company shall have been suspended on any exchange or in any
over-the-counter market, (iii) a general moratorium on commercial banking
activities in New York or Toronto shall have been declared by the applicable
authorities or (iv) there shall have occurred any outbreak or escalation of
hostilities or any change in financial markets or any calamity or crisis that,
in your judgment, is material and adverse, and (b) in the case of any of the
events specified in clauses (a)(i) through (iv), such event singly or together
with any other such event makes it, in your judgment, impracticable to market
the Shares on the terms and in the manner contemplated in the Prospectus.

          11. Effectiveness; Defaulting Underwriters. This Agreement shall
become effective upon the later of (x) execution and delivery hereof by the
parties hereto and (y) release of notification of the effectiveness of the
Registration Statement by the Commission.

          If, on the Closing Date or the Option Closing Date, as the case may
be, any one or more of the Underwriters shall fail or refuse to purchase Shares
that it or they have agreed to purchase hereunder on such date, and the
aggregate number of Shares which such defaulting Underwriter or Underwriters
agreed but failed or refused to purchase is not more than one-tenth of the
aggregate number of the Shares to be purchased on such date, the other
Underwriters shall be obligated severally in the proportions that the number of
Firm Shares set forth opposite their respective names in Schedule I bears to the
aggregate number of Firm Shares set forth opposite the names of all such
non-defaulting Underwriters, or in such other proportions as you may specify, to
purchase the Shares which such Underwriter or Underwriters agreed but failed or
refused to purchase on such date; provided that in no event shall the number of
Shares that any Underwriter has agreed to purchase pursuant to this Agreement be
increased pursuant to this Section 11 by an amount in excess of one-ninth of
such number of Shares without the written consent of such Underwriter. If, on
the Closing Date or the Option Closing Date, as the case may be, any Underwriter
or Underwriters shall fail or refuse to purchase Shares and the aggregate number
of Shares with respect to which such default occurs is more than one-tenth of
the aggregate number of Shares to be purchased on such date, and arrangements
satisfactory to you and the Company




   28

                                                                              27

for the purchase of such Shares are not made within 36 hours after such default,
this Agreement shall terminate without liability on the part of any
non-defaulting Underwriter or the Company. In any such case either you or the
Company shall have the right to postpone the Closing Date or the Option Closing
Date, as the case may be, but in no event for longer than seven days, in order
that the required changes, if any, in the Offering Documents or in any other
documents or arrangements may be effected. Any action taken under this paragraph
shall not relieve any defaulting Underwriter from liability in respect of any
default of such Underwriter under this Agreement.

          If this Agreement shall be terminated by the Underwriters, or any of
them, because of any failure or refusal on the part of the Company to comply
with the terms or to fulfill any of the conditions of this Agreement, or if for
any reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.

          12. Counterparts. This Agreement may be signed in two or more
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

          13. Applicable Law. This Agreement shall be governed by and construed
in accordance with the internal laws of the State of New York.




   29

                                                                              28

          14. Headings. The headings of the sections of this Agreement have been
inserted for convenience of references only and shall not be deemed a part of
this Agreement.

Dear Sirs and Mesdames:

          The undersigned understands that Morgan Stanley & Co. Incorporated
("MORGAN STANLEY") proposes to enter into an Underwriting Agreement (the
"UNDERWRITING AGREEMENT") with Denbury Resources Inc., a Canadian corporation
(the "COMPANY"), providing for the public offering (the "PUBLIC OFFERING") by
the several Underwriters, including Morgan Stanley (the "UNDERWRITERS"), of up
to [ ] shares (the "SHARES") of the Common Stock of the Company (the "COMMON
STOCK").

          To induce the Underwriters that may participate in the Public Offering
to continue their efforts in connection with the Public Offering, the
undersigned hereby agrees that, without the prior written consent of Morgan
Stanley on behalf of the Underwriters, it will not during the period commencing
on the date hereof and ending 120 days after the date of the final prospectus
relating to the Public offering (the "PROSPECTUS"), (i) offer, pledge, sell,
contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, right or warrant to purchase, lend, or
otherwise transfer or dispose of, directly or indirectly, any shares of Common
Stock or any securities convertible into or exchangeable for Common Stock, or
(ii) enter into any swap or other agreement that transfers, in whole or in part,
any of the economic consequences of ownership of the Common Stock, whether any
such transaction described in clause (i) or (ii) above is to be settled by
delivery of Common Stock or such other securities, in cash or otherwise. The
foregoing sentence shall not apply to (a) the sale of any Shares to the




   33

                                                                               2


Underwriters pursuant to the Underwriting Agreement or (b) transactions relating
to shares of Common Stock or other securities acquired in open market
transactions after the completion of the Public Offering. In addition, the
undersigned agrees that, without the prior written consent of Morgan Stanley on
behalf of the Underwriters, it will not, during the period commencing on the
date hereof and ending 120 days after the date of the Prospectus, make any
demand for or exercise any right with respect to, the registration of any shares
of Common Stock or any security convertible into or exchangeable for Common
Stock.

          Whether or not the Public Offering actually occurs depends on a number
of factors, including market conditions. Any Public Offering will only be made
pursuant to an Underwriting Agreement, the terms of which are subject to
negotiation between the Company and the Underwriters.


                                   Very truly yours,
