required by the listing standards adopted by Nasdaq as a result of SEC rulemaking, our Board adopted a Policy for the Recovery of Erroneously
Awarded Compensation. The policy provides that the Company must promptly recover specified incentive-based compensation that is received
by our Section 16 officers on or after December 1, 2023, regardless of fault or misconduct, upon specified accounting restatements of
the Company&#x2019;s financial statements that result in such persons receiving an amount that exceeds the amount that otherwise would
have been received had it been determined based on the restated amounts, computed without regard to any taxes paid. There are limited
exceptions to the recovery required as set forth in the listing standards. Incentive-based compensation is defined as any compensation
that is granted, earned, or vested based wholly or in part upon the attainment of a financial reporting measure. There will not be any
duplicative recovery by the Company. As specified in the listing standards, the Company cannot insure or indemnify a Section 16 officer
for recoveries under this policy.&lt;/span&gt;</ecd:ErrCompAnalysisTextBlock>
