authorized by all actions necessary under                     its governing documents.  

-2- 

        (d)              This
Agreement constitutes a valid and binding obligation of Seller enforceable
          against it in accordance with the terms hereof subject to the effect that
          bankruptcy, insolvency, reorganization, moratorium and similar laws in effect
          from time to time, and no other act, approval or proceeding is required to
          authorize the execution and delivery of this Agreement by Seller or the
          consummation of the transactions contemplated hereby.  

        (e)              Seller
has not incurred any liability, contingent or otherwise, for           brokers’ or

pending or, to the best of Seller’s knowledge, threatened against           Seller
or any of its respective properties, assets, operations or businesses           which
might materially delay, prevent or hinder the consummation of the           transactions
contemplated hereby or materially adversely affect the title to or           value of any
of the Interests.  

        (g)              To
the best of Seller’s knowledge and belief, there are no bankruptcy,

          personal property, fixtures and improvements shall be made “as-is” and
          without any express or implied warranty or representations as to the
          merchantability of any of the wells, equipment, personal property, fixtures and
          improvements or their fitness for any purpose and without any other warranties
          or representation whatsoever except as expressly set forth herein. It is
          understood and agreed that Buyer has or will inspect the property and the
          premises for all purposes and has satisfied itself as to the physical and
          environmental condition of both the surface and subsurface and that Buyer
          accepts the property as is, where is. In addition, there are no warranties or
          representations, either express or implied, as to the accuracy or completeness
          of any data, information or materials heretofore or hereafter furnished in
          connection with the Interests or their ability to produce hydrocarbons. Any and
          all data, information and material furnished by Seller is provided as a
          convenience only and any reliance on or use of the same is at Buyer’s sole
          risk.  

        (i)              To
the best of Seller’s knowledge and belief, there is no lien, security
          interest or encumbrance created by Seller against, upon or with respect to the
          Interests.

              (a)                  Buyer

Agreement and to consummate the transactions contemplated hereby. The           execution
and delivery of this Agreement by Buyer and the consummation of the
          transactions contemplated hereby have been duly authorized by all necessary
          corporate action. This Agreement constitutes the valid and binding obligation
of           Buyer enforceable against it in accordance with the terms hereof, subject to
the           effects of bankruptcy, insolvency, reorganization, moratorium and similar
laws           in effect from time to time, and no other corporate act, approval or
proceeding           on the part of Buyer or the holders of any class of its equity or
debt           securities or any other party is required to authorize the execution and
          delivery of this Agreement by Buyer or the consummation of the transactions
          contemplated hereby. Buyer has all the requisite power and authority to acquire
          and own the Interests.  

              (d)              This
Agreement and the execution and delivery hereof by Buyer do not, and the
          consummation of the transactions contemplated hereby will not, violate any
          provision of or constitute a default (whether with notice or the lapse of time
          or both) under the charter or bylaws of Buyer, or any law or regulation to
which           Buyer or any of its subsidiaries is subject, or any provision of any
indenture,           mortgage, lien, lease, Agreement, instrument, order arbitration
award, judgment           or decree to which Buyer or any of its subsidiaries or any of
their assets or           properties is bound, which violation, breach or default would
materially           adversely affect the business or financial condition of buyer and
its           subsidiaries taken as a whole.  

              (e)              There
are no actions, suits, proceedings or governmental investigations or           inquiries
pending, or threatened, against Buyer or any of its subsidiaries or           their
respective properties, assets, operations or businesses which might           materially
delay, prevent or hinder the consummation of the transactions           contemplated
hereby or which might result if any material adverse change in the           financial
ability of Buyer to consummate the transactions contemplated hereby.  

          (f)       Buyer
has incurred no liability, contingent or otherwise, for brokers’ or finders’
fees relating to the transactions contemplated by this Agreement for which Seller shall
have any responsibility whatsoever. 

               (g)

	Re:	
Grizzly Prospect

McKenzie County, North Dakota

Dear Lynn: 

As we agreed this morning, Hallador
will re-sell its 37.5% interest in Grizzly Prospect to Kodiak on an actual cost basis.
Closing will be on Thursday, December 1, 2005. 

A spreadsheet detailing our jointly
held acreage is attached. We are prepared to assign our interest in this acreage as you
direct and will deliver those assignments to you when requested. In exchange, by noon on
November 29, 2005, Kodiak will wire transfer $1,616,081.17 to our account at US Bank, ABA
102000021, Account #122701609978. 

Our AMI is hereby dissolved, and
Hallador agrees not to compete within that area through December 31, 2007. 

If the above correctly sets forth our
