In connection with the filing of the Prior Prospectus Supplement, the amount of the registration fee was $36,900. As of the date of this prospectus supplement, Common Shares having an aggregate offering price of up to $34,500,000 remain unsold under the Prior Prospectus Supplement. Pursuant to Rule 457(p) under the Securities Act, the registration fee of $5,092.20 that has already been paid and remains unused with respect to the unsold Common Shares previously registered pursuant to the Prior Prospectus Supplement and were not sold thereunder is offset against the registration fee of $61,240 due for this offering. The remaining balance of the registration fee, $56,147.80, has been paid in connection with this offering. The Registrant has terminated the offering that included the unsold Common Shares under the Prior Prospectus Supplement.</ffd:TermntnCmpltnWdrwl>
