ITEM 4.      PURPOSES OF TRANSACTION.

             On October 31, 2002, the Company issued to UBS Capital Americas
III, L.P. ("Americas III") and UBS Capital LLC Convertible Promissory Notes,
which appear as Exhibits C and D hereto (the "Notes"), in the amounts of
$2,755,000 and $145,000, respectively. Each Note accrues interest at a rate
equal to 10% per annum and matures on September 30, 2007 (the "Maturity Date").
At any time prior to the Maturity Date, the holders of the Notes can convert
the principal amount of the Notes plus accrued and unpaid interest into shares
of Series D Preferred Stock (or, if necessary under Delaware law, a new class
of preferred stock having the same rights, preferences, and privileges as the
Series D Preferred Stock) at a conversion price equal to $1.20 per share (as
adjusted for stock splits, combinations, stock dividends and the like) of
Series D Preferred Stock. The Series D Preferred Stock to be issued upon any
such conversion shall have the same rights, preferences and privileges as the
shares of the Series D Preferred Stock described below. In the event that the
holders of the Notes do not own Common Stock at the time of the conversion to
Series D Preferred Stock pursuant to the Notes, then, in addition to the shares
of Series D Preferred Stock issuable as stated above, the holders of the Notes
shall receive 0.0342 shares of Series D Preferred Stock for each dollar of the
Notes plus accrued and unpaid interest converted. Alternatively, in the event
that the Company enters into an agreement to issue "Qualified Financing
Securities" prior to the Maturity Date, then the holders of the Notes can
convert the principal amount of the Notes plus accrued and unpaid interest into
Qualified Financing Securities at a conversion price equal to the purchase
price per Qualified Financing Security. A "Qualified Financing Security" means
a security issued by the Company pursuant to an agreement executed after
October 31, 2002 that provides the Company debt or equity financing in
connection with the issuance of securities by the Company consisting of common
stock or other securities that are convertible, exercisable, or exchangeable
into shares of the Company's common stock

             As previously reported, Americas III and UBS Capital LLC entered
into an Amended and Restated Put Agreement, dated as of August 15, 2002, by and
among the Company, Americas III and UBS Capital LLC (the "Amended and Restated
Put Agreement"), appearing as Exhibit E hereto, pursuant to which Americas III
and UBS AG, through its 100% ownership of UBS Capital LLC, are entitled to
exchange shares of Tutopia for shares of a new class of the Company's
convertible preferred stock and shares of Series D Preferred Stock. Under the
Amended and Restated Put Agreement, until February 29, 2003, Americas III and

ITEM 5.      INTEREST IN SECURITIES OF THE ISSUER.

             (a)    (i)       Based on the Company's Amendment No. 1 to Form
10-K for the year ended June 30, 2002, 11,963,399 shares of Common Stock were
outstanding as of September 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 and 527,775 shares of Series D Preferred Stock issuable
pursuant to the Tutopia Amended and Restated Put Agreement and 2,390,054 shares
of Series D Preferred Stock issuable upon conversion of the Note. Upon
issuance, such shares would be convertible into 5,329,500 shares, 1,055,550
shares and 4,780,108 shares, respectively, of Common Stock, subject to
anti-dilution adjustments. Such Reporting Persons, therefore, beneficially own
approximately 75.0% 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 and 27,778 shares of Series D Preferred Stock issuable pursuant
to the Tutopia Amended and Restated Put Agreement and 125,792 shares of Series
D Preferred Stock issuable upon conversion of the Note. Upon issuance, such
shares would be convertible into 280,500 shares, 55,556 shares and 251,584
shares of Common Stock, respectively, subject to anti-dilution adjustments.
Such holdings represent, in the aggregate, beneficial ownership of
approximately 13.6% of the issued and outstanding Common Stock. UBS AG,
therefore, is the beneficial owner of approximately 75.9% of the issued and
outstanding Common Stock.

                    (iii)     The above percentages were calculated in
accordance with Rule 13d-3(d)(1)(i) of the Securities Exchange Act of 1934.

             (b)    The Reporting Persons have shared power to vote or direct
the vote and dispose or direct the disposition of all shares identified in
paragraph (a)(i) above. UBS AG has sole power to vote or direct the vote and
dispose or direct the disposition of all shares identified in paragraph (a)(ii)
above.

             (c)    Except as described herein, the Reporting Persons have not
effected any transaction in the securities of the Company during the past 60
days.

             (d)    Not applicable.
