BEXP Brigham Exploration (MM)

Statoil ASA (OSLO: STL) (NYSE: STO) ("Statoil") and Brigham Exploration Company (NASDAQ: BEXP) ("Brigham") today announced that more than 92.2 percent of the outstanding shares of Brigham's common stock have been tendered to Statoil (excluding shares purchased by Statoil from Brigham).

The Brigham stockholders have tendered 109,400,549 shares of Brigham common stock, par value $0.01 per share (the "Shares"), to Statoil's indirect, wholly owned subsidiary, Fargo Acquisition Inc. ("Purchaser"), pursuant to the offer to purchase dated October 28, 2011, which, when added to the 6,249,857 Shares separately purchased by Statoil from Brigham, represents more than 92.6 percent of the outstanding Shares. The subsequent offering period expired at 12:00 midnight, New York City time, at the end of Wednesday, December 7, 2011. Purchaser has accepted for payment, and will promptly pay for, all Shares tendered during the subsequent offering period.

As the final step of the acquisition process and following payment for all Shares validly tendered on or prior to the expiration of the tender offer, Statoil and Purchaser expect to effect a short-form merger under Delaware law as promptly as practicable. At the effective time of the merger, each Share issued and outstanding immediately prior to the effective time will cease to be issued and outstanding and (other than Shares then owned by Statoil, Brigham or Purchaser or any of their respective direct and indirect wholly owned subsidiaries and Shares that are held by any stockholders who properly demand appraisal in connection with the merger) will be converted into the right to receive an amount in cash equal to the offer price of US$36.50, without interest thereon and less any applicable withholding taxes. Brigham will be the surviving corporation in the merger and an indirect, wholly owned subsidiary of Statoil. Following the merger, the Shares will be delisted and will cease to trade on the NASDAQ Global Select Market.

Questions and requests for assistance regarding the tender offer may be directed to the information agent for the offer, Innisfree M&A Incorporated at (877) 687-1875 or (212) 750-5833.
