      ASSIGNMENT
OF WORKING INTEREST

       

      


      This
Assignment made this 4th day of August 2005 from PETROLEUM DEVELOPMENT
CORPORATION, a Nevada Corporation, (herein called "Assignor") to PDC 2005B,
Limited Partnership, (herein called "Assignee");

       

      


      WITNESSETH

       

      Assignor,
for the sum of One Dollar ($1.00) and other valuable consideration, the receipt
of which is hereby acknowledged, does by these presents GRANT, BARGAIN, SELL,
EXCHANGE, CONVEY, ASSIGN, TRANSFER, SET OVER and DELIVER unto Assignee all of
the following:

       

      1.      The
specific undivided interest shown in Exhibit A in respect of each of the
oil and gas leases shown in Exhibit A, but only to the extent such leases cover
lands and depths necessary for production of the specific oil and gas well
identified in Exhibit A. This is intended to be a "wellbore assignment."
Assignee shall be entitled to receive that share of production from the well
identified in Exhibit A which is attributable to the undivided interest here
being assigned, but the Assignee shall have, as a result of this Assignment, no
interest whatsoever in any other oil and gas well, whether now existing or
hereafter drilled, which may be located on the lands described in Exhibit A or
on any land pooled therewith. Assignor expressly excepts from this Assignment
and reserves to itself, its successors and assigns, the remainder of the lease
and the leasehold oil and gas estate, including (without limitation) the right
to produce other wells which are or may be located on the lands described in
Exhibit A and lands pooled therewith, without the obligation to account to
Assignee for any such other production.

       

      2.      The
specific undivided interest shown in Exhibit A in all valid unitization,
pooling, operating and communitization agreements, declarations and orders
involving the leasehold interests here being assigned, but only to the extent
that such agreements, declarations and orders relate to the well specifically
identified in Exhibit A and in all other respects limited to the manner as set
forth in Paragraph 1, above.

       

      3.      The
specific undivided interest shown in Exhibit A in all valid oil and gas sales,
purchase, exchange and processing contracts, but only to the extent that such
contracts relate to the well specifically identified in Exhibit A and in all
other respects limited in the manner set forth in Paragraph 1,
above.

       

      4.      The
specific undivided interest shown in Exhibit A in all personal property,
improvements, lease and well equipment, easements, permits, licenses, servitudes
and rights-of-way now owned by Assignor and being used in connection with the
operation of the well specifically identified in Exhibit A or in connection with
the production, treating, storing, transportation or marketing of oil, gas and
other minerals from that well, but in all respects limited in the manner set
forth in Paragraph 1, above.

       

      TO HAVE
AND TO HOLD the interests described unto Assignee, its successors and assigns,
forever.

       

      This
Assignment is made without warranties of any type (whether of title,
merchantability or fitness for a particular use), either express or implied, but
is made with full substitution of Assignee in all covenants and warranties
previously given or made by others, but only to the extent of the interests here
assigned. Assignor does, however, expressly intend that this Assignment convey
any title that Assignor may hereafter acquire to the extent that such
after-acquired title may be necessary to fulfill the interests herein
assigned.

       

      Assignee
shall bear its proportionate share of all burdens on production now of record
and hereby assumes its proportionate share of all other obligations that relate
to the well specifically identified in Exhibit A and the production
therefrom.

       

      Both
Assignor and Assignee hereby agree to execute and deliver such additional
instruments, notices, division orders, transfer orders and other documents as
may reasonably be requested by the other, and to do such other acts and things,
as may be necessary or convenient to accomplish this Assignment in the manner
and to the extent described in Paragraph 1, above.
