Shelf Registration

During the

first

quarter of

2017,

we established a

$250.0

million replacement shelf registration statement. All sales of shares have been and will continue to be made pursuant to an effective shelf registration statement on Form S-

3

filed with the U.S. Securities and Exchange Commission. In addition, in

January 2017

we entered into a Sales Agreement with Cantor, as sales agent, pursuant to which we

may

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

$75.0

million.

During the

first

quarter of

2018,

we sold a total of

1,537,528

shares of our common stock in at-the-market transactions under the Sales Agreement for net proceeds, after deducting commissions and other transaction costs, of approximately

$9.5

million at an average selling price of

$6.33

per share. At

March 31, 2018,

we had

103,100

shares of our common stock subscribed in at-the-market transactions under the Sales Agreement for net proceeds, after deducting commissions and other transaction costs, of approximately

$0.8

million at an average selling price of

$7.50
