Dear Mr. Thompson,

     Pursuant to our telephone conversations on October 12, 13 and 20, 2005,
the Trust hereby submits this application for withdrawal of the Registration
Statement together with all exhibits filed on September 16, 2005 (SEC
Accession No. 0001047469-05-023000) pursuant to Rule 477(a) of the Securities
Act of 1933 (the "Act") (the "Application") .

     The Registration Statement is being withdrawn as the Trust replaces the
Registration Statement with a corrected Registration Statement incorporating
staff comments to the Registration Statement and the consent of Independent
Public Accountants filed on October 19 (SEC Accession No. 0001047469-05-024940).

     Registrant has requested acceleration of the New Registration Statement to
October 21, 2005 pursuant to Rule 461(a). Please issue an order with respect to
this Application as soon as possible.

     Pursuant to the requirements of Rule 478 of the Act, Registrant
represents that no securities were sold in connection with the offering and
this Application for withdrawal of the Amendment has been signed by the
President of the Trust this 20th day of October 2005.

     If you have any questions concerning this filing, please contact me

Sincerely,
