February 14, 2001 CREDIT SUISSE FIRST BOSTON, acting solely on behalf of the Credit Suisse First Boston business unit By: /s/ Lindsay Hollister ----------------------------------- Name: Lindsay Hollister Title: Director Schedule I This Schedule 13G 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 address of the Bank's principal business and office is Uetlibergstrasse 231, P.O. Box 900, CH-8070 Zurich, Switzerland. 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. The Bank owns directly a majority of the voting stock, and all of the non-voting stock, of Credit Suisse First Boston, Inc. ("CSFBI"), a Delaware corporation. 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 ("CSG"), a corporation formed under the laws of Switzerland. CSFBI owns all of the voting stock of Credit Suisse First Boston (USA), Inc. ("CSFB-USA"). Credit Suisse First Boston Corporation ("CSFBC"), a Massachusetts corporation and a registered broker-dealer, is a wholly owned subsidiary of CSFB-USA. The principal business office of CSFBC is 11 Madison Avenue, New York, New York 10010. The securities reported herein are held directly by (i) direct and indirect subsidiaries of CSFB-USA in connection with merchant banking investments, (ii) merchant banking funds advised by subsidiaries of CSFB-USA and (iii) CSFBC in proprietary trading and investment accounts in the ordinary course of business. 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 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: Nuschelerstrasse 1, CH-8070, Zurich, Switzerland. CSG, for purposes of the 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 shares of the securities of the issuer to which this schedule relates (the "Shares") and such Shares are not reported in this statement. Due to the separate management and independent operation of its business units, CSG disclaims beneficial ownership of Shares beneficially owned by its direct and indirect subsidiaries, including the Reporting Person. The Reporting Person disclaims beneficial ownership of Shares beneficially owned by CSG and any of CSG's and the Bank's other business units. -----END PRIVACY-ENHANCED MESSAGE-----
