quarter ended March 31, 2002, 12,776,495 shares of Common Stock were outstanding
as of April 30, 2002. Americas III, UBS Jersey, Advisor and UBS AG are the
beneficial owners of 1,929,326 shares of Series A Preferred Stock, 4,197,349
shares of Series B Preferred Stock, 2,969,930 shares of Series C Preferred Stock
and 4,451,790 shares of Series D Preferred Stock which are currently convertible
into an aggregate of 24,687,084 shares of Common Stock. In addition, the
Reporting Persons beneficially own 5,329,500 shares of New Preferred Stock
issuable at any time pursuant to the Tutopia Put Agreement. Upon issuance, such
shares would be convertible into 5,329,500 shares of Common Stock, subject to
anti-dilution adjustments. Such Reporting Persons, therefore, beneficially own
approximately 70.1% of the issued and outstanding shares of Common Stock.

                           (ii) UBS AG also beneficially owns 101,543 shares of
Series A Preferred Stock, 220,913 shares of Series B Preferred Stock, 156,311
shares of Series C Preferred Stock and 234,305 shares of Series D Preferred
Stock which are currently convertible into an aggregate of 1,299,320 shares of
Common Stock. In addition, UBS AG beneficially owns 280,500 shares of New
Preferred Stock issuable at any time pursuant to the Tutopia Put Agreement. Upon
issuance, such shares would be convertible into 280,500 shares of Common Stock,
subject to anti-dilution adjustments. Such holdings represent, in the aggregate,
beneficial ownership of approximately 11.0% of the issued and outstanding Common
Stock. UBS AG, therefore, is the beneficial owner of approximately 71.2% of the
issued and outstanding Common Stock.
