PDC believes that such treatment~~ will have noan ~~material~~effective ~~impact~~date onof ~~the~~May ~~Registrant's operating~~1, ~~cash flows or cash position~~2010.

As a part of its preparation of the Registrant's second quarter financial statements, the Registrant undertook a review of its accounting for oil and gas derivatives. The Registrant believed that its longstanding derivative accounting treatment was permitted under FAS 133. However, following discussions with KPMG and after a review of the applicable derivative accounting rules, the Registrant's accounting policies and documentation of the Registrant's derivative accounting records, PDC determined that certain of the Registrant's derivatives do not qualify for hedge accounting under FAS 133.

The primary effect of a change in classification of the derivative instrument will be the inclusion of any increases or decreases in the fair value of non-terminated derivative instruments in the calculation of the Registrant's net income for the period in which the increases or decreases in the fair value occur. Under the previous accounting treatment increases and decreases in the fair values of continuing derivative instruments were recorded in AOCI, and did not increase or decrease the net income for the period.

At this time, the Registrant anticipates that it could require as much as four to six weeks to complete the evaluation of the Registrant's derivatives, to determine the impact on the Registrant's financial statements, and to allow KPMG to complete any required review of the Registrant's financial statements. Until the evaluation has been completed, the Registrant is unable to determine whether or not the impact of the review will have a material effect upon the Registrant's net income.
