* The ultimate parent company of Credit Suisse First Boston, Inc.
(formerly known as CS First Boston, Inc.) (CSFBI) is Credit
Suisse Group (formerly known as CS Holding) (CSG). CSG, for
purposes of federal securities laws, may be deemed ultimately to
control CSFBI. CSG, its executive officers and directors and its
direct and indirect subsidiaries, in addition to CSFBI, may
beneficially own shares of the issuer and such shares are not
reported in this statement. CSG disclaims beneficial ownership of
shares beneficially owned by its direct and indirect
subsidiaries, including CSFBI. Effective January 1, 1997, CSG
reorganized its corporate structure. Pursuant to the
reorganization, a direct Swiss bank subsidiary of CSG, Credit
Suisse First Boston (formerly known as Credit Suisse), became the
sole shareholder of CSFBI.
