Other Relationships

From time to time, the Placement
Agent may provide in the future, various advisory, investment and commercial banking and other services to us in the ordinary course of
business, for which it may receive customary fees and commissions. Except as disclosed in this prospectus supplement, we have no present

fee shall be paid in lieu of a number of warrants equal to $250,000 as described in the immediately preceding sentence (and, if previously
issued, a number of warrants equal to $250,000 shall be cancelled). In addition, Wainwright shall receive reimbursement of reasonable
out-of-pocket expenses, including legal fees and expenses, incurred by Wainwright in connection with financial
