     Brigham Exploration Announces Plans to Force Convert Series A Warrants

    AUSTIN, Texas, Nov. 4 /PRNewswire-FirstCall/ -- Brigham Exploration
Company (Nasdaq: BEXP) announced today that it has notified CSFB Private
Equity that it will exercise its right to require CSFB to exercise its
warrants to purchase 6.7 million shares of Brigham common stock.  In
connection with this exercise, Brigham will retire $20 million of its Series A
mandatorily redeemable preferred stock.

    WARRANT EXERCISE
    The warrants were issued in connection with Brigham's sale of $20 million
of Series A preferred stock to CSFB in November 2000. Brigham can require CSFB
to exercise the warrants if the average price of Brigham's common stock trades
above $5.00 per share each day for 60 consecutive days.  CSFB can use either
$20 million in cash or $20 million of Series A preferred stock to exercise the
warrants.  In the event CSFB uses cash, Brigham will be required to retire a
like amount of Series A preferred.  Brigham will receive no additional
proceeds from the exercise of the warrants.  The 6.7 million shares issued
upon the exercise of the warrants have not been registered under the
Securities Act of 1933.  Subsequent to the exercise, Brigham will have
approximately 34.6 million shares of common shares outstanding.  Brigham
expects the warrant exercise to be completed by mid November 2003.

    MANAGEMENT COMMENTS
    Gene Shepherd, Brigham's Chief Financial Officer, commented, "Over the
last several years we've significantly deleveraged our balance sheet.  By
converting the 6.7 million warrants, and thus the first tranche of the CSFB
preferred stock, we've again substantially reduced our corporate debt
leverage.  Furthermore, this conversion will free up additional capital that
can be put to work creating reserve value for our shareholders, as we will no
longer be paying a dividend on the Series A preferred with a $20 million
liquidation value.  The dividend, which has historically equated to
$1.6 million per year, can also be viewed as a reduction to the Brigham cost
structure."
