    of additional securities as may be issued after the date hereof as a result of stock splits, stock dividends or similar transactions.
    Proposed Maximum Offering Price Per Unit is estimated solely for the purpose of computing the amount of the registration fee pursuant
    to Rule 457(c) under the Securities Act of 1933, as amended, based upon the average of the high and low prices for a share of the
    Registrant&#x2019;s common stock as reported on the Nasdaq Global Market on August 31, 2026, which date is a date within five business
    days of the filing of this registration statement.&lt;/span&gt;
