("MBP"), which is a Delaware limited partnership. (4) These securities are held directly by DLJ Offshore Partners III, C.V. ("Offshore"), which is a Netherlands Antilles limited partnership.

("MBIII Inc."), a Delaware corporation, is the managing member of MBIII LLC, Managing General Partner of MBP and Advisory General Partner of Offshore. MBIII Inc. is a wholly owned subsidiary of DLJCI. (9) Credit Suisse First Boston (USA) Inc. ("CSFB-USA"), a Delaware corporation formerly named Donaldson, Lufkin & Jenrette, Inc., is the sole stockholder of DLJCI and LBO. (10) This Form 4 is being filed by Credit Suisse First Boston (the "Bank"), a Swiss bank, on behalf of itself and its subsidiaries, to the extent that they constitute part of the Credit Suisse First Boston business unit (the "CSFB business unit" or the "Reporting Person"). The CSFB business unit is engaged in the corporate and investment banking, trading (equity, fixed income and foreign exchange), private equity investment and derivatives businesses on a worldwide basis. The Bank and its subsidiaries engage in other separately managed activities, most of which constitute the independently operated Credit Suisse Asset Management business unit; the Credit Suisse Asset Management business unit provides asset management and investment advisory services to institutional investors worldwide. Credit Suisse First Boston, Inc. ("CSFBI"), a Delaware corporation, owns 100% of the voting stock of CSFB-USA. The Bank owns a majority of the voting stock, and all of the non-voting stock, of CSFBI. The ultimate parent company of the Bank and CSFBI, and the direct owner of the remainder of the voting stock of CSFBI, is Credit Suisse Group, a corporation formed under the laws of Switzerland ("CSG"). The principal business of CSG is acting as a holding company for a global financial services group with five distinct specialized business units that are independently operated. In addition to the two business units referred to above, CSG and its consolidated subsidiaries (other than the Bank and its subsidiaries) are comprised of (a) the Credit Suisse Private Bank business unit that engages in the global private banking business; (b) the Credit Suisse business unit that engages in the Swiss domestic banking business and (c) the Winterthur business unit that engages in the global insurance business. CSG's business address is Paradeplatz 8, Postfach 1, CH-8070, Zurich, Switzerland. CSG, for purposes of federal securities laws, may be deemed ultimately to control the Bank, and the CSFB business unit. CSG, its executive officers and directors, and its direct and indirect subsidiaries (including all of the business units except the CSFB business unit), may beneficially own securities issued by the Issuer or derivative securities relating thereto, and any such securities are not reported in this statement. Due to the separate management and independent operation of its business units, CSG disclaims beneficial ownership of any such securities beneficially owned by its direct and indirect subsidiaries, including the Reporting Person. The Reporting Person disclaims beneficial ownership of any such securities beneficially owned by CSG and any of CSG's and the Bank's other business units. The Reporting Person disclaims beneficial ownership of securities held directly by any entity described herein except with respect to the Reporting Person's proportionate interest in or ownership of such entity. The filing of this statement shall not be construed for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, as an admission of beneficial ownership of the securities reported on this statement. (11) The securities reported herein were purchased pursuant to a Securities Purchase Agreement dated as of March 5, 2001, between Brigham Exploration Company, Funding III, MBP, Offshore and ESC II (the "Agreement"). Pursuant to the Agreement, each of Funding III, MBP, Offshore and ESC II paid $20.00 per unit of securities (the "Unit"), with each Unit consisting of (i) one share of Series A Preferred Stock and (ii) Warrants to purchase 4.210526 shares of Common Stock.
