Ladies and Gentlemen:

     We have acted as securities  counsel to Denbury  Resources Inc., a Delaware
corporation ("Denbury"), in connection with a registration statement on Form S-3
(the "Registration  Statement"),  being filed by Denbury with the Securities and
Exchange  Commission  (the  "Commission")  under the  Securities Act of 1933, as
amended (the "Act"),  which relates to common stock,  par value $.001 per share,
of Denbury  ("Common  Stock"),  preferred  stock,  par value $.001 per share, of
Denbury in one or more series ("Preferred Stock"), unsecured debt securities, in
one or more  series,  consisting  of notes,  debentures  or other  evidences  of
indebtedness of Denbury ("Debt Securities"), shares of Preferred Stock which may
be issued in the form of depositary shares  ("Depositary  Shares")  evidenced by
depositary  receipts,  and warrants to purchase  Common Stock or Preferred Stock
("Warrants") which may be issued and sold by Denbury,  and Common Stock owned by
certain of its shareholders  ("Selling  Shareholders")  which may be sold by the
Selling Shareholders,  in each case from time to time pursuant to Rule 415 under
the Act for an aggregate  initial  offering price (as to all such  securities as
may be sold by Denbury and the Selling Shareholders) not to exceed $350,000,000.
The Common  Stock,  Preferred  Stock,  Debt  Securities,  Depositary  Shares and
Warrants  will be  referred  to herein  collectively  as the  "Securities".  The
Securities  will be offered in amounts,  at prices and on terms to be determined
in light of market conditions  contained in the Registration  Statement to which
this opinion is an exhibit.

     Unless otherwise  provided in any prospectus  supplement  forming a part of
the Registration  Statement (i) any series of the Debt Securities will be issued
under an Indenture (the "Indenture") between Denbury and a United States banking
institution to be selected by Denbury,  as trustee,  a form of which is filed as
an exhibit to the Registration Statement; (ii) any series of the Preferred Stock
will be issued under Denbury's Certificate of Incorporation and a Certificate of
Designations (the "Certificate of Designations"); (iii) any shares of the Common
Stock are to be issued under Denbury's  Certificate of  Incorporation;  (iv) any
Depositary  Shares will be issued under one or more Deposit  Agreements  (each a
"Deposit  Agreement") to be entered into between Denbury and  depositories to be
named by Denbury  (each a  "Depository");  and (v) any  Warrants  will be issued
under one or more Warrant Agreements (each a "Warrant  Agreement") to be





entered into between  Denbury and warrant  agents to be named by Denbury (each a
"Warrant Agent").

     In  connection  with this  opinion,  we have  examined  and relied upon the
accuracy  of  original,  certified  or  photographic  copies  of  such  records,
agreements,  certificates  and other  documents  as we have deemed  necessary or
appropriate to enable us to render the opinions set out below, including (i) the
Registration Statement,  (ii) Denbury's Certificate of Incorporation and Bylaws;
(iii)  copies  of  resolutions  of  Denbury's   board  of  directors   ("Board")
authorizing  the  filing  of the  Registration  Statement;  and (iv) the form of
Indenture.  In  addition,  we have  reviewed  such  questions  of law as we have
considered appropriate. As to any facts material to our opinion, we have made no
independent  investigation of such facts and have relied,  to the extent that we
deem such reliance proper, upon certificates of public officials and officers or
other representatives of Denbury.

     In  all  such  examinations,   we  have  assumed  the  genuineness  of  all
signatures,  the legal  capacity of natural  persons,  the  authenticity  of all
documents submitted to us as originals,  the conformity to original documents of
all  documents  submitted  to us as  certified  or  photostatic  copies  and the
authenticity of the originals of such latter documents.

     We have also assumed that (i) the Registration Statement and any amendments
thereto (including  post-effective  amendments) will have become effective under
the Act and comply with all applicable laws, (ii) a proper prospectus supplement
("Prospectus  Supplement") will have been prepared and filed with the Commission
describing the Securities  offered thereby,  (iii) all Securities issued will be
issued and sold in compliance with applicable  federal and state securities laws
and  solely  in  the  manner  stated  in  the  Registration  Statement  and  the
appropriate  Prospectus  Supplement,  (iv)  the  Indenture,  together  with  any
supplemental  indenture  or other  instruments  establishing  a  series  of Debt
Securities  to be issued  under  the  Indenture,  will each be duly  authorized,
executed and delivered by the parties thereto in substantially the form reviewed
by us or with changes that do not affect the opinions  given  hereunder;  (v) at
the time of any  offering  or sale of any  shares of Common  Stock or  Preferred
Stock,  Denbury  will have such  number of shares of Common  Stock or  Preferred
Stock  authorized  or created and  available  for issuance as may be offered and
sold and as are  issuable  upon the  conversion,  exchange  or  exercise  of any
Securities  that  may  be  offered  and  sold,  (vi)  any  definitive  purchase,
underwriting  or similar  agreement with respect to any Securities  offered will
have been duly authorized and validly  executed and delivered by Denbury and the
other  parties  thereto,  (vii)  there shall be no change in law  affecting  the
validity  of any of the  Securities  (between  the date  hereof  and the date of
issuance  and sale of such  Securities),  and (viii) all  parties to  agreements

                                       2


involving the issuance or sale of the Securities will perform their  obligations
