BRIGHAM EXPLORATION CLOSES FINANCINGS TO FUND 2000 DRILLING PROGRAM

- --------------------------------------------------------------------------------

         Austin, TX -- (Business Wire) - February 22, 2000 -- Brigham
Exploration Company (NASDAQ:BEXP) today announced that it has entered into a
series of financing agreements that provide funding for its planned 2000 capital
expenditure program and working capital obligations. These transactions include
(i) a restructuring of its senior credit facility to provide from $14 million to
$19 million in borrowing availability, (ii) amendments to the terms of its
senior subordinated notes to provide for the restructured credit facility and
additional financial flexibility, and (iii) the issuance of $4.5 million of
common stock and warrants to purchase common stock in a private placement.
Through these related financing transactions, Brigham has secured a total of
$18.5 million to $23.5 million in capital availability to fund its planned $20
million drilling program in 2000.

         Brigham has entered into an amended senior credit facility with its
existing lenders, Bank of Montreal and Societe Generale, and a new lender, Shell
Capital Inc. This amended facility provides the Company with $70 million in
borrowing availability for a three-year term, an increase from the $56 million
in availability under the existing facility. If Brigham exceeds certain asset
value and interest coverage tests in the second or third quarters of 2000, the
total borrowing availability under this credit facility will increase to $75
million. Borrowings under the senior credit facility in excess of $45 million
are convertible into shares of Brigham common stock in the following amounts:
(i) the first $10 million of borrowings is convertible at $3.90 per share, (ii)
the second $10 million is convertible at $6.00 per share and (iii) the final $10
million is convertible at $8.00 per share. All borrowings under the senior
credit facility bear interest at annual rates of LIBOR plus 3.00%, or
approximately 8.875% based on current LIBOR rates.

         In its amendments to the terms of its outstanding $45.5 million of
senior subordinated notes due 2003 (the "Notes"), the Company has been granted
an extension of its right to pay interest through the issuance of additional
Notes in lieu of cash (or "in-kind") through the third quarter of 2000, and
potentially through the fourth quarter of 2000 if certain conditions are met. In
exchange for the amendments to the Notes, the Company has agreed to grant to the
holders of the Notes a term overriding royalty interest that provides for the
limited right to receive 4%, or 3% if certain conditions are met, of the
Company's net production revenue to reduce any Notes that have been or will be
issued as interest paid in-kind.

         Brigham has also agreed to issue 2,195,122 shares of common stock and
731,707 warrants to purchase common stock for total consideration of $4.5
million in a private placement to a group of institutional investors led by
affiliates of two members of the Company's board of directors. The equity sale
consists of units that include one share of common stock priced at $2.05 per
share and one-third of a warrant to purchase Brigham common stock at an exercise
price of $2.5625 per share with a three-year term. Pricing of this private
equity placement was based on the average market price of Brigham common stock
during a twenty trading day period prior to issuance.

         Curtis Harrell, the Company's Chief Financial Officer, stated, "We are
pleased to announce the closing of this significant series of coordinated
financing transactions for our Company. Despite the recent improvements in
market prices for crude oil and natural gas, capital available for investment in
exploration and production firms remains a challenge for our sector. We view the
investments by Shell Capital, a sophisticated, high-quality energy investor, and
members of our board of directors to be indicative of the substantial value that
exists in our undrilled prospect inventory. Through this combination of debt and
equity financings, we have successfully raised the capital necessary to fund our
planned drilling projects in 2000. We have positioned Brigham to continue to
create value through the execution of our balanced exploration and development
drilling program which should yield further opportunities to improve our
capitalization and capital resources during 2000."
