Explanation of Responses:
01: The Reporting Person is a managing director of Goldman Sachs (Asia) L.L.C.,
an affiliate of The Goldman Sachs Group, Inc. ("GS Group"). Goldman, Sachs & Co.
("Goldman Sachs") is an indirect wholly-owned subsidiary of GS Group. GS Group
may be deemed to own beneficially and directly 1,234,042 shares of Common Stock.
Goldman Sachs and GS Group may be deemed to own beneficially and indirectly, in
the aggregrate, 493,616 shares of Common Stock through certain investment
partnerships of which affiliates of Goldman Sachs and GS Group are the general
partner or managing general partner (the "Investment Partnerships"). The
Reporting Person disclaims beneficial ownership of the securities reported
herein as indirectly owned, except to the extent of her pecuniary interest
therein, if any.
02: These options may be deemed to have been granted pursuant to the Issuer's
1999 Non-Employee Directors' Stock Option Plan, which as of the date of the
Issuer's initial public offering had provided that upon the Issuer's initial
public offering all non-employee directors would automatically receive a grant
of options to purchase 5,000 shares of the Issuer Common Stock. This automatic
grant was intended to apply to new non-employee directors but not to existing
non-employee directors (such as the Reporting Person), and the Issuer's 1999
Non-Employee Directors' Stock Option Plan has been revised accordingly. To the
extent that these options are deemed to have been granted, they have been
cancelled with no value received.
03: These options were granted to the Reporting Person pursuant to the Issuer's
1999 Non-Employee Directors' Stock Option Plan. The Reporting Person has an
understanding with GS Group pursuant to which she holds the stock options for
the benefit of GS Group.
