ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         The funds or other consideration by which the Reporting Persons
acquired the Common Stock were previously described in the Initial Schedule 13D.
No funds or other consideration were otherwise obtained for the purpose of
acquiring, holding, trading or voting the securities. Temple Interests, L.P.
acquired 199,391 shares of Common Stock pursuant to a conversion of 30,700
shares of Series B 8% Convertible Preferred Stock on August 20, 2001. T.L.L.

         The number of shares of Common Stock beneficially owned by the
Reporting Persons does not constitute a majority of the outstanding shares of
Common Stock and is insufficient to permit them to exercise control over
Pioneer.
