respects subject to the terms,  definitions and provisions,  of the 2004 Omnibus
Stock and Incentive  Plan For Denbury  Resources  Inc.  (the  "Plan"),  which is
incorporated  herein by  reference  except  to the  extent  otherwise  expressly
provided in this Option.

1. Option Price. The Option Price is  __________________  for each Share,  which
price is the Fair Market Value of a Share on the Date of Grant.

2. Vesting of Option  Shares.  The Option Shares shall remain 100%  forfeitable,
until the fourth  (4th)  anniversary  of the Date of Grant,  and on such  fourth
(4th)  anniversary  of the Date of Grant,  this Option shall become 100% Vested,
and all Option  Shares  subject  to this  Option  shall  become  "Vested  Option
Shares".  Without  limiting the  generality of the forgoing,  in the event that,
prior to the fourth (4th) anniversary of the Date of Grant,  either (i) Optionee
incurs a Separation by reason of Optionee's death, or Disability,  or (ii) there
is a Change in Control,  then all of the Option Shares which have not previously
become  Vested Option Shares shall become Vested Option Shares as of the date of
such death, disability or Change in Control.

3.  Exercisability of Option.  This Option shall not be exercisable prior to the
first date on which Option Shares become Vested Option  Shares,  and  thereafter
(and prior to the termination of this Option), this Option shall be exercisable,
in whole or in part, with respect to Vested Option Shares.

     (a) Method of Exercise. Without limitation,  this Option shall be exercised
by a written notice delivered to the Administrator which shall:

          (i) state the election to exercise the Option and the number of Vested
     Option Shares in respect of which it is being exercised; and

     Administrator,  of the rights of such  person or persons  to  exercise  the
     Option.

     shall be paid by the  Optionee  to the  Administrator  in  cash,  or by the
     delivery  of Shares held by Optionee  for at least 6 months  (which  period
     may, in the sole  discretion  of the  Administrator,  be  increased  to the
     extent the Administrator  deems necessary in order to avoid a charge to the
     Company's  earnings),  or both. To the extent Shares are used in payment of
     the Option Price, the value of such Shares shall be their Fair Market Value
     on the date of delivery to the Administrator.

     (c)  Issuance of Shares.  No person  shall be, or have any of the rights or
privileges  of, a holder of the Shares  subject to this Option  unless and until

by the  Administrator,  the Optionee shall deliver this Option and other written
agreements  executed by the Company and the Optionee with respect to this Option
to the  Administrator  who  shall  endorse  or cause to be  endorsed  thereon  a
notation of such exercise and return all agreements to the Optionee.

representative shall have the right to exercise this Option.

6. No Right To  Continued  Employment.  Neither the Plan nor this  Option  shall
