Ladies and Gentlemen:

     We have acted as securities  counsel to Denbury  Resources  Inc.  (formerly
Denbury Holdings,  Inc.), a Delaware corporation (the "Company"),  in connection
with the Post-Effective  Amendment No. 1 to Registration Statement No. 333-63198
on Form S-8  (the  "Registration  Statement"),  filed  by the  Company  with the
Securities and Exchange  Commission (the "Commission")  under the Securities Act
of 1933, as amended (the "Act"),  with respect to the Company's  adoption of the
Registration  Statement as the  successor  issuer to Denbury  Resources  Inc., a
Delaware  corporation,  as it was constituted prior to 9:00 a.m. EST on December
29, 2003 (the "Predecessor"),  pursuant to Rule 414 of the Act. The Registration
Statement  covers  shares of common  stock,  par value  $.001 per share,  of the
Company's  ("Common  Stock"),  that  may be  issued  by the  Company  under  the
Predecessor's Stock Option Plan (the "Option Plan"),  which Option Plan has been
adopted and assumed by the Company.

     In connection therewith,  we have examined and relied upon the original, or
copies identified to our satisfaction,  of (1) the Certificate of Incorporation,
as amended,  and the Bylaws, as amended, of the Company; (2) minutes and records
of the corporate  proceedings of the Company and the Predecessor with respect to
the Option Plan,  the  issuance of the Common Stock  pursuant to the Option Plan
and related matters;  (3) the Registration  Statement and exhibits thereto,  (4)
the Option Plan, as amended;  and (5) such other documents and instruments as we
have deemed necessary for the expression of the opinions herein contained.

     In making the foregoing  examinations,  we have assumed the  genuineness of
all  signatures  and  the  authenticity  of  all  documents  submitted  to us as
originals,  and the conformity

to  original  documents  of  all  documents  submitted  to  us as  certified  or
photostatic  copies.  As to various  questions of fact material to this opinion,
and  as  to  the  content  of  the  Registration  Statement,  minutes,  records,
resolutions and other documents or writings of the Company,  we have relied,  to
the extent deemed reasonably  appropriate,  upon representations or certificates
of  officers  or  directors  of the  Company  and upon  documents,  records  and
instruments  furnished  to us by  the  Company,  without  independent  check  or
verification of their accuracy.

     Based upon our  examinations,  and the consideration of, and reliance upon,
the documents and other matters described above, and assuming that:

     (1) the Common  Stock to be issued in the future under the Option Plan will
be duly issued and sold in  accordance  with the terms of the Option  Plan,  and
pursuant to the terms of options  issued under and in accordance  with the terms
of the Option Plan,

     (2) the Company  maintains an adequate  number of  authorized  but unissued
shares and/or treasury shares for issuance of Common Stock to be issued pursuant
to options granted under the Option Plan, and

     (3) the  consideration  for the Common Stock issued pursuant to exercise of
options  issued  under the Option  Plan is  actually  received by the Company as
provided in the Option Plan and exceeds the par value of such Common  Stock,  we
are of the opinion that the Common Stock issued or sold in  accordance  with the
terms of the Option Plan, and pursuant to options issued under and in accordance
with the terms of the Option Plan, will be duly and validly  issued,  fully paid
and nonassessable.

     The opinions expressed herein are limited to the General Corporation Law of
the State of Delaware,  and the federal laws of the United States of America and
we assume no  responsibility  as to the  applicability  thereto,  or the  effect
thereon,  of the laws of any other  jurisdiction.  You should be aware that this
firm is not  admitted to the  practice  of law in the State of Delaware  and the
opinion  herein as to the  General  Corporation  Law of the State of Delaware is
based solely upon  unofficial  compilations  thereof.  We hereby  consent to the
filing of this  opinion  as an  exhibit to the  Registration  Statement  and any
amendments  thereto  and to  references  to us included in or made a part of the
Registration  Statement.  In giving this  consent,  we do not admit that we come
within the category of persons whose consent is required  under Section 7 of the
Securities  Act or the Rules and  Regulations  of the  Securities  and  Exchange
Commission thereunder.
