Explanation of Responses:

(1) Class B Common Stock is convertible  into Common Stock on a one for one
basis at the option of the holder, provided,  however, that the aggregate number
of shares of voting  common  stock  into  which the Class B Common  Stock may be
exchanged may not exceed 4.9% of the shares of common stock then outstanding.

(2) As a result of internal  reorganizations  and name changes effective as
of the first week of January 2001, the general partner of the reporting  person,
JPMP Master Fund Manager,  L.P. ("MF Manager"),  formerly known as Chase Capital
Partners,  became a limited  partnership and all but one of its general partners
became a limited partner of the partnership.  The internal  reorganizations  and
name changes did not alter the proportionate  interests of the ultimate security
holders of the renamed entities.

Explanotory Notes:


     1) The names of the Reporting  Persons and the Designated  Reporter changed
during the first week of January  2001 as a result of  internal  reorganizations
and name changes  effective as of various  times during the week. As part of the
reorganizations,  Chase Capital  Partners (now J.P.  Morgan Partners Master Fund
Manager,  L.P.)  became a  limited  partnership  and all but one of its  general
partners   became   limited   partners   of  the   partnership.   The   internal
reorganizations  and name changes did not alter the  proportionate  interests of
the  limited  partners  or of the  ultimate  security  holders  of  the  renamed
entities.  The  Designated  Reporter is  executing  this report on behalf of all
Reporting Persons, each of whom has authorized it to do so. Each of such Persons
disclaims  beneficial  ownership of the securities to the extent it exceeds such
Person's pecuniary interest therein.

     2) The amounts shown in Table II represent the beneficial  ownership of the
Issuer's equity  securities by J.P. Morgan  Partners  (BHCA),  L.P. (f/k/a Chase
Equity Associates,  L.P.), a portion of which may be deemed  attributable to the
Reporting  Person  because the  Reporting  Person is the general  partner of JPM
BHCA.  The actual  pro rata  portion of such  beneficial  ownership  that may be
deemed to be  attributable to the Reporting  Person is not readily  determinable
because it is  subject to several  variables,  including  the  internal  rate of
return and vesting of interests within JPM BHCA.

     3) The amounts shown in Table II represent the beneficial  ownership of the
Issuer's  equity  securities  by JPM  BHCA,  a  portion  of which  may be deemed
attributable  to the Reporting  Person because the Reporting  Person is the sole
stockholder  of JPMP Master  Fund  Manager,  L.P.  ("MF  Manager"),  the general
partner of JPM BHCA.  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 the internal
rate of return and vesting within JPM BHCA and MF Manager.

     4) The amounts  shown in Table II  represent  beneficial  ownership  of the
Issuer's  equity  securities  by JPM  BHCA,  a  portion  of which  may be deemed
attributable to the Reporting  Person because it is the sole  stockholder of (a)
JPMP  Capital  Corporation,  the  general  partner of MF Manager and (b) Chatham
Ventures,  Incorporated,  the limited  partner of JPM BHCA.  The actual pro rata
portion of such  beneficial  ownership that may be attributable to the Reporting
Person is not readily  determinable  because it is subject to several variables,
including the internal  rate of return and vesting of interests  within JPM BHCA
and MF Manager.

     5) The amounts shown in Table II represent the beneficial  ownership of the
Issuer's  equity  securities  by JPM  BHCA,  a  portion  of which  may be deemed
attributable  to the Reporting  Person because it is the sole limited partner of
JPM BHCA. The actual pro rata portion of such  beneficial  ownership that may be
deemed to be  attributable to the Reporting  Person is not readily  determinable
because it is  subject to several  variables,  including  the  internal  rate of
return and vesting of interests within JPM BHCA.
