Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
We periodically conduct evaluations (pursuant
to Rule 13a-15(b) of the Exchange Act), under the supervision and with the participation of management, of the effectiveness of our disclosure
controls and procedures (as defined in Rule 13a-15(e)) as of the end of the period covered by this report.
These disclosure controls and procedures are
designed to ensure that information required to be disclosed in our reports that are filed or submitted under the Exchange Act is recorded,
processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Our disclosure controls and
procedures include, without limitation, controls and procedures designed to ensure that this information is accumulated and communicated
to management, including the principal executive and principal financial officers, or persons performing similar functions, as appropriate,
to allow timely decisions regarding required disclosure.
Based on the evaluation, our Chief Executive
Officer and Chief Financial Officer have concluded that these disclosure controls and procedures were effective as of the end of the
period covered by this report.
Changes in Internal Control over Financial Reporting
Other than the resignation of our Vice
President/Corporate Controller, Paul Palz, effective September 14, 2022, there were no other changes in our internal control over financial
reporting that occurred during the quarter ended September 30, 2022, that have materially affected, or are reasonably likely to materially
