PLAN OF DISTRIBUTION
We have entered into an At Market Issuance Sales Agreement, or the sales agreement, with Ladenburg Thalmann & Co. Inc., or Ladenburg,
B. Riley Securities, Inc., or B. Riley Securities, Roth Capital Partners, LLC, or Roth Capital Partners, as sales agents, under which we are permitted to offer and sell shares of our common stock having an aggregate offering price of up to
$100,000,000 through a sales agent acting as sales agent or directly to a sales agent or agents acting as principal from time to time. The sales, if any, of the shares made under the sales agreement may be made by means of transactions that are
deemed to be at the market offerings as defined in Rule 415 under the Securities Act, including block trades and sales made in ordinary brokers transactions on The Nasdaq Capital Market or otherwise at market prices prevailing at
the time of sale, at prices related to prevailing market prices or at negotiated prices.
If we sell any of the shares of common stock
covered by this prospectus supplement in a transaction which is not an at-the-market offering, we expect to enter into a separate agreement with the sales
agent or agents participating in such transaction and we will, if material, describe the terms of such transaction in a pricing supplement.
On any day on which our common stock is traded on The Nasdaq Capital Market (each, a trading day), we may sell shares through only
one sales agent and, if we determine to do so, we will instruct the applicable sales agent as to the maximum number of shares or dollar amounts to be sold on such trading day, the minimum price per share at which such shares may be sold, and other
parameters. Subject to the terms and conditions of the sales agreement, such sales agent will use its commercially reasonable efforts, consistent with its normal trading and sales practices and applicable law and regulations, to sell on our behalf
all of the designated shares in accordance with such instruction. We or the sales agent through whom the sale of shares is to be made as sales agent on any trading day may suspend the offering of shares for any reason and at any time, upon notifying
the other party.
If acting as sales agent, the applicable sales agent will provide to us written confirmation following the close of
trading on The Nasdaq Capital Market on each trading day on which shares are sold under the sales agreement. Each confirmation will include the number of shares sold on that day, the aggregate gross sales proceeds of the shares, the net proceeds to
us (after deduction of any transaction fees, transfer taxes or similar taxes or fees imposed by any governmental entity or self-regulatory organization in respect of such sales) and the aggregate compensation payable by us to such sales agent with
respect to such sales. We will report, on a quarterly basis, the number of shares sold by or through the sales agents during such quarterly fiscal period, the net proceeds received by us and the aggregate compensation paid by us to the sales agents
with respect to such sales.
We will pay an aggregate commission of up to 3.0% of the gross sales price of the shares sold through any of
the sales agents in at-the-market transactions. For any transaction that is not an
at-the-market transaction, the fees payable to the agent or agents participating in such transaction will be as agreed to between us and such agent or
agents. We have agreed to reimburse the sales agents for certain of their legal expenses in connection with the establishment and maintenance of the ATM program.
Settlement for sales of shares will occur on the second business day that is also a trading day following the trade date on which such sales
are made, unless another date is agreed to in writing by us and the applicable sales agent.
The offering of common stock pursuant to the
sales agreement will terminate upon the earlier of (1) the sale of all shares subject to the sales agreement or (2) the termination of the sales agreement by us or by the sales agents, which may occur for any reason, at any time, by us or
a sales agent, as to itself, upon the giving of written notices to the other parties.
In connection with the sale of the shares on our
behalf, the sales agents may be deemed underwriters within the meaning of the Securities Act, and the compensation paid to the sales agents may be deemed to be
