Date: August 26, 1999    CREDIT SUISSE FIRST BOSTON, acting solely on behalf of
                         the Credit Suisse First Boston business unit

                         By: /s/   William W. Chandler
                              ------------------------
                         Name:     William W. Chandler
                         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 consolidated 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's registered head office is located at
Uetlibergstrasse 231, P.O. Box 900, CH-8045 Zurich, Switzerland. The Bank and
its consolidated 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 Corporation ("CSFBC"), a Massachusetts corporation, a
broker-dealer registered under Section 15 of the Securities Exchange Act of 1934
and an indirect majority owned subsidiary of the Bank, directly beneficially
owns the securities reported herein. The principal business office of CSFBC is
11 Madison Avenue, New York, New York 10010. CSFBC is a wholly owned subsidiary
of Credit Suisse First Boston, Inc. ("CSFBI"), a Delaware corporation. 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 owner of the
remainder of the voting stock of CSFBI, is Credit Suisse Group ("CSG"), a
corporation formed under the laws of Switzerland. 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 certain 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
Common Stock, 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 of Common Stock beneficially owned by
its direct and indirect subsidiaries, including the Reporting Person. The
Reporting Person disclaims beneficial ownership of shares of Common Stock
beneficially owned by CSG and any of CSG's and the Bank's other business units.
