(a) The Reporting Persons may be deemed to beneficially own, in the aggregate, 16,695,928 Shares, representing approximately 17.02% of the Issuer's outstanding Shares (based upon approximately 98,109,615 Shares stated to be outstanding as of February 28, 2017 by the Issuer in the Issuer's Quarterly Report on Form 10-Q for the quarter ended January 31, 2017).
