Explanation of Responses:
(1) Pursuant to an internal reorganization effective as of January 1, 2000, (i)
Chase Equity Associates, LLC ("CEA, LLC") became the successor to Chase Equity
Associates, LP ("CEA, LP"), and (ii) CCP-CMC Consolidating, LLC
("Consolidating"), a newly-organized affiliate of Chase Capital Partners ("CCP")
became the managing member of CEA, LLC. Mr. Chavkin is a general partner of CCP.
CCP is the managing member of Consolidating, and pursuant to a master advisory
agreement with Consolidating, the manager, by delegation, of CEA, LLC. Prior to
the internal reorganization, CCP was the general partner, and the sole
shareholder of Consolidating was the limited partner, of CEA, LP. The internal
reorganization changed CEA, LP's name and form of organization but did not alter
the proportionate interests of its ultimate security holders.
(2) CEA, LLC is the record owner of the shares. Mr. Chavkin disclaims beneficial
ownership of such securities except to the extent of his pecuniary interest
therein.
(3) These shares are owned by Chase Manhattan Capital L.P. which is an affiliate
of Chase Equity Associates. Mr. Chavkin disclaims beneficial ownership of such
securities except to the extent of his pecuniary interest therein.
(4) Each share of Class C Common Stock is convertible into one share of Class A
Common Stock at the option of the holder upon the occurrence of certain events.
