The percentage of shares of Common Stock reported as being beneficially owned by the Wynnefield Reporting Persons is based upon 29,332,832 shares of Common Stock outstanding as of April 6, 2021, as reported in the Issuer’s Quarterly Report on Form 10-Q for the fiscal quarter ended February 28, 2021, filed with the Commission on April 8, 2021, plus 8,303 shares of Common Stock issuable to Mr. Obus pursuant to RSU Rights that are exercisable within 60 days of the date hereof.

The following table sets forth certain information with respect to shares of Common Stock directly beneficially owned by the Wynnefield Reporting Persons listed below:

Obus and Landes may be deemed to be the indirect beneficial owner (as that term is defined under Rule 13d-3 under the Exchange Act) of the Common Stock that WCM may be deemed to beneficially own. Each of Messrs. Obus and Landes, as co-managing members of WCM, share the power to direct the voting and disposition of the shares of Common Stock that WCM may be deemed to beneficially own.

The filing of this Schedule 13D and any future amendment by the Wynnefield Reporting Persons, and the inclusion of information herein and therein with respect to WCM, WCI and Messrs. Obus and Landes, shall not be considered an admission that any of such persons, for the purpose of Section 16(b) of the Exchange Act, are the beneficial owners of any shares in which such persons do not have a pecuniary interest.
