During the

first

we filed a shelf registration statement on Form S-

) that permitted: (a) the offering, issuance and sale of up to a maximum aggregate offering price of

$250

million of our common stock, preferred stock, debt securities, warrants, rights and/or units; and (b) as part of the

$250

million, the offering, issuance and sale by us of up to a maximum aggregate offering price of

$75

million of our common stock under our sales agreement with Cantor in

one

or more ATM offerings. During the

third

quarter of

2018,

we raised

$70.0

million, net of underwriting discounts and commissions and offering expenses, in an underwritten public offering of

9.1

million shares of common stock at a public offering price of

$8.25

per share, and we sold a total of

0.6

million shares of our common stock in ATM transactions under the sales agreement for net proceeds, after deducting commissions and other transaction costs, of approximately

$4.8

million at an average selling price of

$8.36

per share.

On

October 12, 2018,

we filed a new shelf registration statement on Form S-

3

(File

No.

-

227805

), which was declared effective by the SEC on

October 24, 2018.

The new shelf registration replaced our prior shelf registration statement, pursuant to which

no

additional securities will be offered or sold. The new shelf registration statement permits: (a) the offering, issuance and sale of up to a maximum aggregate offering price of

$250

million of our common stock, preferred stock, debt securities, warrants, rights and/or units; and (b) as part of the

$250

million, the offering, issuance and sale by us of up to a maximum aggregate offering price of

$75

million of our common stock under our sales agreement with Cantor in

one

or more ATM offerings. In addition, in

October 2018

we entered into a new sales agreement with Cantor, as sales agent, which replaced the previous sales agreement from

January 2017.

Pursuant to the new sales agreement, we

may

offer and sell through Cantor, from time to time, shares of our common stock up to an aggregate offering price of

$75

million. All offers and sales under the sales agreement have been and will continue to be made pursuant to an effective shelf registration statement on Form S-

3

filed with the SEC.
