                        NOTES TO THE UNAUDITED CONDENSED
                       CONSOLIDATED FINANCIAL STATEMENTS


1.     ORGANIZATION AND NATURE OF OPERATIONS

       Brigham Exploration Company (the "Company") is a Delaware corporation
       formed on February 25, 1997 for the purpose of exchanging its common
       stock for the common stock of Brigham, Inc. and the partnership
       interests of Brigham Oil & Gas, L.P. (the "Partnership"). Brigham, Inc.
       is a Texas corporation whose only asset is its ownership interest in the
       Partnership. The Partnership was formed in May 1992 to explore and
       develop onshore domestic natural gas and oil properties using 3-D
       seismic imaging and other advanced technologies. Since its inception,
       the Partnership has focused its exploration and development of natural
       gas and oil properties in the Permian and Hardeman Basins of West Texas,
       the Anadarko Basin and the onshore Gulf Coast.

       Pursuant to an exchange agreement dated February 26, 1997 (the "Exchange
       Agreement") and upon the initial filing on February 27, 1997 of a
       registration statement with the Securities and Exchange Commission for
       the public offering of common stock (the "Offering"), the shareholders
       of Brigham, Inc. transferred all of the outstanding stock of Brigham,
       Inc. to the Company in exchange for 3,859,821 shares of common stock of
       the Company. Pursuant to the Exchange Agreement, the Partnership's other
       general partner and the limited partners also transferred all of their
       partnership interests to the Company in exchange for 3,314,286 shares of
       common stock of the Company. Furthermore, the holders of the
       Partnership's subordinated convertible notes transferred these notes to
       the Company in exchange for 1,754,464 shares of common stock. These
       transactions are referred to as the "Exchange." In completing the
       Exchange, the Company issued 8,928,571 shares of common stock to the
       stockholders of Brigham, Inc., the partners of the Partnership and the
       holder of the Partnership's subordinated notes payable. As a result of
       the Exchange, the Company now owns all the partnership interests in the
       Partnership.

       In May 1997, the Company sold 3,325,000 shares of its common stock in
       the Offering at a price of $8.00 per share. With a portion of the
       proceeds from the Offering, the Company repaid the outstanding
       borrowings, $13.3 million, under the Partnership's revolving credit
       facility.

2.     BASIS OF PRESENTATION

       The unaudited condensed consolidated balance sheets at December 31, 1996
       and March 31, 1997 reflect the accounts of the Partnership at December
       31, 1996 and the consolidated accounts of the Company at March 31, 1997,
       respectively. The unaudited condensed consolidated statements of
       operations and of cash flows for the three months ended March 31, 1996
       and 1997 include the results of operations and of cash flows of the
       Partnership for the three months ended March 31, 1996 and the period
       from January 1, 1997 to February 27, 1997 and for the Company the period
       from February 25, 1997, the date of its inception, to March 31, 1997. As
       the Exchange was the conversion of a partnership into a corporation, the
       Exchange has been accounted for by the Company as a reorganization.

       The accompanying consolidated financial statements are unaudited, and in
       the opinion of management, reflect all adjustments that are necessary
       for a fair presentation of the financial position and results of
       operations for the periods presented. All such adjustments are of a
       normal and recurring nature. The results of operations for the periods
       presented are not necessarily indicative of the results to be expected
       for the entire year. The unaudited condensed consolidated financial
       statements should be read in conjunction with the Predecessors'
       historical consolidated financial statements and notes thereto as of and
       for the period ended December 31, 1996 as included in the Company's
       Registration Statement on Form S-1 (333-22491) filed with the Securities
       and Exchange Commission.

                        NOTES TO THE UNAUDITED CONDENSED
                       CONSOLIDATED FINANCIAL STATEMENTS


3.     UNAUDITED PRO FORMA INFORMATION

       The Partnership's legal form has no relation to the capital structure of
       the Company after the Exchange. As a result, historical loss per unit
       amounts are not relevant and have not been presented. Pro forma net
       income (loss) per common share and pro forma, as adjusted, net income
       per common share are presented giving effect to the number of shares
       outstanding subsequent to the Exchange (8,928,574 shares) and giving
       effect to employee stock options granted on March 4, 1997, as if these
       shares and options had been issued at the beginning of each period
       presented. The effect of the stock option grants on pro forma net income
       (loss) per common share and pro forma, as adjusted, net income per
       common share was calculated using the treasury stock method.

       Pro forma net income (loss) reflects pro forma exchange adjustments
       primarily representing the amortization of compensation expense related
       to employee stock options granted upon formation of the Company, the
       reduction of interest expense related to the transfer of the
       subordinated notes payable to the Company as part of the Exchange, and
       related income tax effects. In addition to the effect of these pro forma
       adjustments, pro forma, as adjusted, net income has been adjusted to
       exclude the $5.0 million deferred tax charge recorded by the Company on
       February 27, 1997 (see Note 4), as this was a nonrecurring charge
       related to the Exchange.

4.     INCOME TAXES

       Prior to consummation of the Exchange, the Partnership was not subject
       to federal income taxes. Income and losses were passed through to its
       partners on the basis of the allocation provisions established by the
       partnership agreement. Upon consummation of the Exchange, the
       Partnership became subject to federal income taxes through its ownership
       by the Company. Also in conjunction with the Exchange, the Company
       recorded a deferred income tax liability of $5.0 million to recognize
       the temporary differences between the financial statement and tax bases
       of the assets and liabilities of the Partnership at the Exchange date,
       February 27, 1997, given the provisions of enacted tax laws.

5.     FUTURE REPORTING REQUIREMENTS

       In February 1997, the Financial Accounting Standards Board issued
       Statement of Financial Accounting Standards No. 128 ("SFAS 128"),
       Earnings Per Share ("EPS"). SFAS 128 replaces the presentation of
       primary EPS with a presentation of basic EPS and requires a dual
       presentation of basic and diluted EPS on the face of the income
       statement for all entities with complex capital structures. Basic EPS
       excludes dilutive securities and is computed by dividing income
       available to common stockholders by the weighted-average number of
       common shares outstanding for the period. Diluted EPS reflects the
       potential dilution that could occur if dilutive securities were
       converted into common stock and is computed similarly to fully diluted
       EPS pursuant to previous accounting pronouncements. SFAS 128 is
       effective for periods ending after December 15, 1997, including interim
       periods, and earlier application is not permitted. SFAS 128 requires
       restatement of all prior period EPS data presented.

ITEM 2.   Management's Discussion and Analysis of Results of Operations and 
          Financial Condition

Results of Operations

Comparison of three month periods ended March 31, 1996 and March 31, 1997

         Natural gas and oil sales. Natural gas and oil sales increased 52%
from $1.4 million in the first quarter of 1996 to $2.1 million in the first
quarter of 1997. Of this increase, approximately $348,000 or 48% was
attributable to an increase in production, and approximately $383,000 or 52%
was attributable to an increase in the average sales price for natural gas and
oil. Production volumes for natural gas increased 75% from approximately
139,000 Mcf in the first quarter of 1996 to approximately 243,000 Mcf in the
first quarter of 1997. The average price received for natural gas increased 54%
from $2.01 per Mcf in the first quarter of 1996 to $3.10 per Mcf in the first
quarter of 1997. Production volumes for oil increased 6% from approximately
60,000 Bbls in the first quarter of 1996 to approximately 63,000 Bbls in the
first quarter of 1997. The average price received for oil increased 18% from
$18.55 per Bbl in the first quarter of 1996 to $21.82 per Bbl in the first
quarter of 1997. Natural gas and oil sales were increased by production from
wells completed since the first quarter of 1996 partially offset by the natural
decline of existing production. Natural gas and oil sales in the first quarter
of 1996 include one month of production related to certain properties sold at
the end of January 1996.

         Lease operating expenses. Lease operating expense increased 12% from
$184,000 ($.37 per Mcfe) in the first quarter of 1996 to $206,000 ($.33 per
Mcfe) in the first quarter of 1997. This increase is primarily due to an
increase in the number of producing wells. The decrease in the per unit rate is
due to the sale of higher cost oil wells in January 1996 and an increase in the
percentage of production from natural gas wells.

         General and administrative expenses. General and administrative
expenses increased 43% from $491,000 ($.98 per Mcfe) in the first quarter of
1996 to $702,000 ($1.13 per Mcfe) in the first quarter of 1997. The increase is
a result of payroll costs related to additional employees and charges related
to the relocation of the principal executive offices to Austin, Texas.

         Depletion of natural gas and oil properties. Depletion of natural gas
and oil properties increased 35% from $510,000 ($1.02 per Mcfe) in the first
quarter of 1996 to $687,000 ($1.10 per Mcfe) in the first quarter of 1997 as a
result of higher production volumes.

         Interest expense. Interest expense increased 81% from $215,000 in the
first quarter of 1996 to $390,000 in the first quarter of 1997. This increase
was due to a higher average outstanding balance in the first quarter of 1997
and a higher effective interest rate. The weighted average outstanding debt
balance increased 63% from $16.0 million in the first quarter of 1996 to $26.1

million in the first quarter of 1997. The effective interest rate increased 16%
from 5.0% in the first quarter of 1996 to 5.8% in the first quarter of 1997.
The increase in the average outstanding balance was a result of the $10.1
million average outstanding balance under the Company's revolving credit
facility entered into in April 1996. The revolving credit facility had an
effective interest rate of 8.5% at March 31, 1997.

         Income taxes. Prior to consummation of the Exchange, the Partnership
was not subject to federal income taxes. Income and losses were passed through
to its partners on the basis of the allocation provisions established by the
partnership agreement. Upon consummation of the Exchange, the Partnership
became subject to federal income taxes through its ownership by the Company.
Also in conjunction with the Exchange, the Company recorded a deferred income
tax liability of $5 million to recognize the temporary differences between the
financial statement and tax bases of the assets and liabilities of the
Partnership at the Exchange date, February 27, 1997, given the provisions of
enacted laws.

Liquidity and Capital Resources

         The Company's primary sources of capital have been borrowings
(revolving credit facility and private placement debt), working capital and the
sale of interests in projects. During May 1997, as described in Note 1 to the
Unaudited Condensed Consolidated Financial Statements included herein, the
Company completed an initial public offering of Common Stock of the Company
that generated proceeds of approximately $24 million, net of offering costs,
that was used to repay all outstanding debt ($13.25 million) under the
revolving credit facility and to fund capital expenditures.


         In the first quarter of 1997, the Company generated $4.2 million in
cash flow from operations as compared to $1.1 million in the first quarter of
1996 primarily as a result of an increase in natural gas and oil revenues, net
of production taxes, lease operating expenses and general and administrative
expenses. Cash flow used in investing activities was $7.3 million in the first
quarter of 1997 primarily as a result of capital expenditures. Cash flow
provided by financing activities was $2.8 million in the first quarter of 1997
as a result of borrowings under the revolving credit facility.

         The Company expects to continue its exploration and production
activities during the remainder of 1997 and expects to finance those activities
with proceeds from the initial public offering, borrowings under the revolving
credit facility and cash flow from operations.
