Item 7 Identification and Classification of the Subsidiary Which Acquired the
Security Being Reported on By the Parent Holding Company:
A Schedule 13G with respect to beneficial ownership of the Common Stock of the
Company was jointly filed on behalf of Dillon, Read Holding Inc., Dillon, Read
Inc., and Dillon, Read & Co. Inc. on February 13, 1997.  Effective September
2, 1997, Dillon, Read Holding Inc., the parent of Dillon, Read Inc. and
Dillon, Read & Co. Inc., merged with and into SBC/DRH Merger, Inc., a wholly
owned direct subsidiary of Swiss Bank Corporation.  Dillon, Read Holding Inc.
was the corporate survivor of the transaction and it then changed its name to
SBC Warburg Dillon Read Holding Inc.  On that same date, Dillon, Read & Co.
Inc. merged with and into SBC Warburg, Inc., a wholly owned indirect
subsidiary of Swiss Bank Corporation.  Dillon, Read & Co. Inc. was the
corporate survivor of the transaction and it then changed its name to SBC
Warburg Dillon Read Inc.  In connection with the above-described mergers, the
ownership of certain investment funds that had been deemed to be affiliates of
Dillon, Read & Co. Inc., including certain investment funds that held Common
Stock of the Company, were restructured and ceased to be deemed affiliates of
Dillon, Read & Co. Inc., now known as SBC Warburg Dillon Read Inc.  Therefore,
as of September 2, 1997, the holdings of such investment funds were no longer
aggregated with the holdings of SBC Warburg Dillon Read Inc. and consequently
as of such date, SBC Warburg Dillon Read Inc. ceased to hold greater than 5%
of the Common Stock of the Company.
