On December 18, 2019, the Company and Agent entered into an Amended and Restated equity distribution agreement (the “Equity Distribution Agreement”). Pursuant to the Equity Distribution Agreement, the Company may sell up to 500,000 shares of 9.00% Series A Cumulative Preferred Stock (the “Preferred Stock”), par value $1.00 per share through an at-the-market (“ATM”) offering program administered by the Agent.

Under the Equity Distribution Agreement, the Agent will be entitled to compensation of up to 2.0% of the gross proceeds from the sale of Preferred Stock under the ATM offering program. As of January 31, 2020, we had issued 994,046 shares of our Series A Preferred Stock.

Gross proceeds from these sales for the three and six months ended July 31, 2019 were approximately $1.7 million and $2.1 million, respectively, and the Agent received compensation of approximately $34,000 and $42,000, respectively.
