| | (a) | The
reason described in reasonable detail in Part III of this Form could not be eliminated without unreasonable effort or expense; |
| | | |
| ☒ | (b) | The subject annual report, semi-annual report, transition
report on Form 10-K, Form 20-F, Form 11-K, Form N-CEN or Form N-CSR, or portion thereof, will be filed on or before the fifteenth

The Registrant is unable to file its Quarterly Report on Form 10-Q for the three months ended February 28, 2026 (the “Report”)
by the prescribed date of April 14, 2026 without unreasonable effort or expense because the Registrant needs additional time to

is estimated that operating expenses will decrease by approximately $187,000, primarily due to an approximately $91,000 decrease in wages
and related expenses and an approximately $72,000 decrease in professional fees. It is estimated that other expenses will increase by
approximately $82,000, primarily due to an estimated $112,000 increase in interest expense from debt discount expense offset by an estimated
$30,000 decrease in interest expense related parties. |
