BRIGHAM, INC. 401(K) PLAN NOTES TO FINANCIAL STATEMENTS 1. DESCRIPTION OF THE PLAN The following description of the Brigham, Inc. 401(k) Plan (the "Plan") provides only general information. Participants should refer to the Plan documents for a more complete description of the Plan provisions, a copy of which is available from Brigham, Inc. (the "Company"). GENERAL The Plan is a successor to the Brigham Oil & Gas, L.P. 401(k) Plan which was originally effective as of September 19, 1996. Effective January 1, 1998, Brigham Oil & Gas, L.P. assigned its sponsorship of the Plan to Brigham, Inc. and the Plan's name was changed to the Brigham, Inc. 401(k) Plan. Effective January 1, 1999, the Plan was restated concurrent with a change in the Plan's third-party administrator and trustee. The Plan is subject to the provisions of the Employee Retirement Income Security Act ("ERISA"). The Plan is a defined contribution plan created for the benefit of the employees of the Company. The Plan covers all employees who are 21 years of age and have completed six months of service. Employees may enroll in the Plan on the first day of January, April, July or October of each year. The Plan is administered by the Company, who has appointed Invesmart, Inc. (formerly Plan Data, Inc.) as a third party administrator. The Plan's assets are held by a trust fund administered by The Charles Schwab Trust Company. CONTRIBUTIONS A participant may contribute a portion of his/her pre-tax compensation in amounts up to the maximum deferral permitted under the Internal Revenue Code. For 1999, this limit was the lesser of 25% or $10,000. At its discretion and to be determined annually, the Company may make matching contributions to the Plan. The Company may also make an additional annual, discretionary profit sharing contribution. For 1999, the Company made no discretionary contributions. INTERFUND TRANSFERS Participants may change their percentage contributions once per calendar quarter on Plan enrollment dates. Participants may change fund allocations as frequently as desired and at any time. VESTING Plan participants are fully vested at all times in their participant contributed assets. The Plan provides for vesting of assets contributed by the Company of 20% after two years of service and 20% additional vesting for each additional year of service thereafter until the sixth year, at which time the employer contributed assets are fully vested. Participants are automatically fully vested in their accounts upon retirement, disability or death, as defined in the Plan. 3 BRIGHAM, INC. 401(K) PLAN NOTES TO FINANCIAL STATEMENTS BENEFIT PAYMENTS Plan participants may receive a lump sum payment of all vested benefits upon retirement, disability, death or termination of employment. A participant may also make hardship withdrawals, subject to certain rules and restrictions, from the vested portion of his/her account. PARTICIPANT LOANS The Plan includes a provision that permits participants to borrow a minimum of $1,000 and up to the lesser of 50% of the value of the vested portion of their Plan assets or $50,000. The loans are payable through payroll deductions in principal installments plus interest at prime plus 2% through payroll deductions. General purpose loans are due over terms up to 5 years. Primary residence loans are due over terms up to 30 years. ADMINISTRATIVE EXPENSES Costs and expenses incurred in administering the Plan, excluding certain fees and expenses of the trustee and investment manager, are paid by the Company. 2. ACCOUNTING POLICIES BASIS OF ACCOUNTING The accompanying financial statements have been prepared on the accrual basis of accounting. The trustee holds and manages the funds and distributes cash to the Plan participants. The assets of the Plan are invested in separate funds managed by independent registered investment advisors and/or in Brigham Exploration Company stock. VALUATION OF INVESTMENTS Short term investments and loans to participants are stated at cost, which approximates fair value. Quoted market prices are used to value investments. Shares of mutual funds are valued at the net asset value of shares held by the Plan at year-end. The plan presents in the statement of changes in net assets available for benefits the net appreciation (depreciation) in the fair value of its investments, which consists of the realized gains or losses and the unrealized appreciation (depreciation) on those investments. 4 BRIGHAM, INC. 401(K) PLAN NOTES TO FINANCIAL STATEMENTS THE USE OF ESTIMATES IN PREPARING FINANCIAL STATEMENTS The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates that affect the reported amounts in the financial statements and accompanying notes and schedule. Actual results could differ from those estimates. RECENT ACCOUNTING PRONOUNCEMENTS On September 15, 1999, the American Institute of Certified Public Accountants issued Statement of Position 99-3, ACCOUNTING FOR AND REPORTING OF CERTAIN DEFINED CONTRIBUTION PLAN INVESTMENTS AND OTHER DISCLOSURE MATTERS ("SOP 99-3") which, among other things, eliminated previous requirements for defined contribution plans to present plan investments by general type for participant-directed investment programs and to disclose participant -directed investment programs. SOP 99-3 is effective for financial statements for Plan years ending after December 15,1999. Accordingly, the accompanying financial statements do not include details of the Plan's participant-directed investment programs. 3. PLAN TERMINATION Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants become fully vested in their accounts. 4. INCOME TAX STATUS Management believes that the Plan is qualified under Section 401(a) of the Internal Revenue Code and is therefore exempt from taxation under Section 501. Generally, contributions to a qualified plan are deductible by the Company when made, earnings of the trust are tax exempt and participants are not taxed on their benefits until withdrawn from the Plan. Management is unaware of any variations in the operation of the Plan from the terms of the Plan documents. The Plan has complied with the fidelity bonding requirement of ERISA. 5 BRIGHAM, INC. 401(k) PLAN SCHEDULE H, LINE 4(i) - ASSETS HELD FOR INVESTMENT PURPOSES AT END OF YEAR (Unaudited) INVESTMENTS AT DECEMBER 31, 1999 IDENTITY OF ISSUE, BORROWER, DESCRIPTION OF CURRENT LESSOR OR SIMILAR PARTY INVESTMENT VALUE *Brigham Exploration Company Common stock $ 32,533 Stock Liquidity Fund Cash $ 11 BT Investment International International stock mutual fund $ 69,971 Janus Worldwide Fund Stock mutual fund $ 85,368 Fasciano Fund Stock mutual fund $ 94,675 Janus Twenty Fund Stock mutual fund $371,706 MFS Massachusetts Invest.
