PLAN OF DISTRIBUTION
Pursuant to this prospectus supplement and the accompanying prospectus, we are offering up to $75,000,000 in shares of our Common Stock that
may be issued by us directly to Lincoln Park from time to time over the 36-month term of the Purchase Agreement and 701,262 shares of our Common Stock to Lincoln Park as Commitment Shares, pursuant to the
Purchase Agreement and subject to the terms and subject to the conditions set forth therein. This prospectus supplement and the accompanying prospectus also cover the resale of these shares by Lincoln Park to the public. See Lincoln Park
Transaction.
The Purchase Agreement provides that, from
time-to-time over the term of the Purchase Agreement, on any business day, and at our sole discretion, we may require Lincoln Park to purchase up to 200,000 shares of
our Common Stock as a Regular Purchase, which may be increased to up to 400,000 shares, if the closing price of our Common Stock exceeds certain threshold prices set forth in the Purchase Agreement, subject to a maximum of purchase commitment of
Lincoln Park of $2,000,000 per Regular Purchase. The foregoing share amounts and related market prices will be adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock
split or other similar transaction occurring after the date of this prospectus supplement. We and Lincoln Park may mutually agree to increase such limit. In addition, under certain circumstances set forth in the Purchase Agreement, we may, upon
notice to Lincoln Park, from time to time and at our sole discretion, direct Lincoln Park to purchase additional shares of our Common Stock in Accelerated Purchases, and Additional Accelerated Purchases as set forth in the Purchase Agreement. The
purchase price per share is based on the market price of our Common Stock at the time of sale as computed under the Purchase Agreement. Lincoln Park may not assign or transfer its rights and obligations under the Purchase Agreement. See the section
entitled The Lincoln Park Transaction above.
Lincoln Park is an underwriter within the meaning of
Section 2(a)(11) of the Securities Act. Lincoln Park has informed us that it will use an unaffiliated broker-dealer to effectuate all sales, if any, of the Common Stock that it may purchase from us pursuant to the Purchase Agreement. Such sales
will be made on Nasdaq at prices and at terms then prevailing or at prices related to the then current market price. Each such unaffiliated broker-dealer will be an underwriter within the meaning of Section 2(a)(11) of the Securities Act.
Lincoln Park has informed us that each such broker-dealer will receive commissions from Lincoln Park that will not exceed customary brokerage commissions.
We know of no existing arrangements between Lincoln Park and any other stockholder, broker, dealer, underwriter, or agent relating to the sale
or distribution of the shares offered by this prospectus supplement.
We will pay all of the expenses incident to the registration,
offering, and sale of the shares to Lincoln Park.
We have agreed to indemnify Lincoln Park and certain other persons against certain
liabilities in connection with the offering of shares of Common Stock offered hereby, including liabilities arising under the Securities Act or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such
liabilities.

representatives or affiliates engaged in or effected, in any manner whatsoever, directly or indirectly, any short sale (as such term is defined in Rule 200 of Regulation SHO of the Exchange Act) of our Common Stock or any hedging transaction, which
establishes a net short position with respect to the Common Stock. Lincoln Park agreed that during the term of the Purchase Agreement, it, its agents, representatives or affiliates will not enter into or effect, directly or indirectly, any of the
foregoing transactions.
