RELEASE

FOR IMMEDIATE RELEASE

Austin, Texas, February 7, 2013 – Whiting USA Trust I (NYSE Symbol – WHX) announced the first Trust distribution in 2013, which relates to net profits generated during the fourth quarterly payment period of 2012.

Unitholders of record on February 19, 2013 will receive a distribution amounting to $8,008,030 or $0.577618 per unit, which is payable on or before March 1, 2013.

Volumes, average sales prices and net profits for the quarterly payment period were:

The net profits interest represents the right to receive 90% of the net proceeds from Whiting Petroleum Corporation’s interests in certain existing oil and natural gas producing properties located primarily in the Rocky Mountains, Mid-Continent, Permian Basin and Gulf Coast regions of the United States. The net profits interest will terminate when 9.11 MMBOE have been produced and sold from the underlying properties (which amount is equivalent to 8.20 MMBOE attributable to the net profits interest), and the Trust will soon thereafter wind up its affairs and terminate, after which it will pay no further distributions.

As of December 31, 2012, on a cumulative accrual basis, 6.10 MMBOE (74%) of the Trust’s total 8.20 MMBOE have been produced and sold. Based on the Trust’s reserve report for the underlying properties as of December 31, 2012, the 9.11 MMBOE of reserves (8.20 MMBOE to the 90% net profits interest) are projected to be produced from the underlying properties by June 30, 2015, which reflects expected year over year decline rates ranging from approximately 9% to 11% between 2013 and 2015. However, the rate of future production cannot be predicted with certainty, and 9.11 MMBOE (8.20 MMBOE to the 90% net profits interest) may be produced before or after the currently projected date. In addition, cash distributions to unitholders may decline at a faster rate than the rate of production due to fixed and semi-variable costs attributable to the underlying properties.

This press release contains forward-looking statements, including all statements made in this press release other than statements of historical fact. No assurances can be given that such statements will prove to be correct. The announced distributable amount is based, in part, on the amount of cash received or expected to be received by the Trust from Whiting Petroleum Corporation pursuant to the net profits interest with respect to the relevant quarterly period. Any differences in actual cash receipts by the Trust could affect this distributable amount. Other important factors that could cause actual results to differ materially include expenses of the Trust, fluctuations in oil and natural gas prices, uncertainty of estimates of oil and natural gas reserves and production, risks inherent in the operation and production of oil and gas properties, and future production costs. Statements made in this press release are qualified by the cautionary statements made in this press release. The Trustee does not intend, and assumes no obligation, to update any of the statements included in this press release.
