Explanation of Responses:
(1) The amount shown represents the beneficial ownership of the Issuer's
securities by Chase Equity Associates, LP ("CEA, LP"), a portion of which
may be deemed attributable to the reporting person because the reporting
person is a partner of Chase Capital Partners ("CCP"), which is the general
partner and manager of CEA, LP. The actual pro rata portion of such
beneficial ownership that may be deemed attributable to the reporting
person is not readily determinable because it is subject to several
variables including CEA, LP's and CCP's internal rate of return and
vesting. The reporting person disclaims beneficial ownership of the
securities to the extent it exceeds his pecuniary interest.
(2) Each share of Class B Non-Voting Common Stock is convertible into 1 share
of Common Stock at the option of the holder upon the occurrence of certain
events.
