State below in reasonable  detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR,
N-CSR, or the transition  report or portion  thereof,  could not be filed within
the prescribed time period.

Due to the Company's  current cash position,  the Company has been unable to pay
its outside  auditors the required  fees to complete the review of the Company's
financial  statements to be included in the Company's  Quarterly  Report on Form
10-Q for the quarter ended March 31, 2007 ("Form 10-Q").  The Company is working

Company is unable to predict when it will be in a position to file the 10-Q.
