The Prior Registration Statement registered securities for primary offerings in accordance with Rule 415 with a proposed maximum aggregate offering price of $400,000,000, in respect of which the registrant paid a filing fee of $59,040 (based on the filing fee rate in effect at the time of the filing of the Prior Registration Statement). As of the date hereof, the registrant has sold an aggregate of $88,735,921 of such securities under the Prior Registration Statement, leaving a balance of $311,264,079 of unsold securities, of which the $200,000,000 of Unsold Securities are being included in this registration statement. Of the $59,040 filing fee previously paid, $29,520 is associated with the Unsold Securities and, pursuant to Rule 415(a)(6), will continue to be applied to the Unsold Securities under this registration statement. No new securities are being registered, and no additional registration fee is due in connection with this registration statement. To the extent that, after the filing date hereof and prior to the effectiveness of this registration statement, the registrant sells any Unsold Securities pursuant to the Prior Registration Statement, the registrant will identify in a pre-effective amendment to this registration statement the updated amount of Unsold Securities from the Prior Registration Statement to be included in this registration statement pursuant to Rule 415(a)(6). Pursuant to Rule 415(a)(6), the offering of securities under the Prior Registration Statement will be deemed terminated as of the date of effectiveness of this registration statement.
