If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)

(a)	The reason described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense
(b)	The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q, or subject distribution report on Form 10-D, or  portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and
(c)	The accountant’s statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.

PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

We determined that we were unable to file our Form 10-Q for the quarter ended March 31, 2009 by the May 15, 2009 due date or by the May 22, 2009 extension date.

We are not able to file a timely Form 10-Q for the quarter ended March 31, 2009, because we have not completed the closing process of our books and records necessary to prepare the required financial statements for previous reporting periods.  In November 2005, we determined that all previously issued financial statements, as noted in Part IV – Other Information, should no longer be relied upon and were being restated.

Since November 2005, Petroleum Development Corporation (“PDC”), as the managing general partner, has undertaken an evaluation of its accounting and reporting processes and has developed a plan to bring us current with our SEC reporting obligations.  Our current plan is to file a single comprehensive Form 10-K containing information for all periods from January 1, 2005 through December 31, 2007 as soon as practicable to be followed by the filing of a comprehensive Form 10-K containing information for the year ended December 31, 2008.  Following the 2008 Form 10-K filing, our plan is to make additional filings to address our SEC reporting requirements for 2009.

Because of the matters discussed above, management expects to have material weaknesses in its internal controls over financial reporting.
