from the results anticipated by these forward-looking statements. These important factors include those that we discuss under the heading &#147;Risk Factors&#148; and in other sections of our Annual Report on Form

shall automatically be reduced, if applicable, to 80% of the VWAP Calculation, and the per share exercise price for the Warrant shall automatically be reduced, if applicable, to 110% of the VWAP Calculation; provided, that in no event, will the per
share purchase price for the Common Stock or the exercise price for the Warrants be less than $8.322.&nbsp;In the event, the per share exercise price for the Warrants is adjusted, then the number of shares exercisable under the Warrants shall be
increased so&nbsp;that the aggregate exercise price payable after adjustment is equal to the aggregate exercise price payable prior to such adjustment. The maximum number of shares of Common Stock, and shares of Common Stock underlying the Warrants,
issuable under the Purchase Agreement is 2,855,014. The Company received aggregate gross proceeds received of approximately $10&nbsp;million for the purchase of the Common Stock and the Warrants. The Company will not receive any additional
consideration in the event the number of shares of common stock and shares of common stock underlying the warrants are adjusted. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In
connection with the Private Placement, the Company entered into a registration rights agreement (the &#147;Registration Rights Agreement&#148;) with the Purchasers Pursuant to the Registration Rights Agreement, the Company agreed to prepare and file
a registration statement (the &#147;Resale Registration Statement&#148;) with the SEC by March&nbsp;30, 2018 for purposes of registering the resale of&nbsp;the shares of Common Stock and the shares of Common Stock issuable upon exercise of the
Warrants. The Company also agreed to use its reasonable best efforts to cause this registration statement to be declared effective by the SEC by April&nbsp;23, 2018 (May 23, 2018 in the event the registration statement is reviewed by the SEC). If
the Company fails to meet the specified filing deadlines or keep the Resale Registration Statement effective, subject to certain permitted exceptions, the Company will be required to pay liquidated damages to the Purchasers in&nbsp;an amount equal
to one percent (2.0%) of the aggregate purchase price for any unregistered shares then held by the Purchasers and for each subsequent month such shares remain unregistered. The maximum aggregate liquidated damages payable to the Purchasers is twelve
percent (12.0%) of the aggregate purchase price. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company also agreed, among other things, to indemnify the selling holders under the

holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. The common stock has no preemptive or conversion rights or
other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of common stock are fully paid and nonassessable, and the shares of common stock to be issued upon the closing of

have the effect of decreasing the market price of the common stock. As of the closing of the offering, no shares of preferred stock will be outstanding. We currently have no plans to issue any shares of preferred stock. </P>

the effect of delaying, deterring or preventing another party from acquiring control of us. These provisions and certain provisions of Delaware law, which are summarized below, are expected to discourage coercive takeover practices and inadequate
takeover bids. These provisions are also designed, in part, to encourage persons seeking to acquire control of us to negotiate first with our board of directors. We believe that the benefits of increased protection of our potential ability to

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our amended and restated bylaws require advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as
directors, other than nominations made by or at the direction of our board of directors or a committee of our board of directors. These provisions may have the effect of precluding the conduct of certain business at a meeting if the proper
procedures are not followed. These provisions may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer&#146;s own slate of directors or otherwise attempting to obtain control of our company.

is divided into three classes, one class of which is elected each year by our stockholders. The directors in each class will serve three-year terms. A third party may be discouraged from making a tender offer or otherwise attempting to obtain
control of us as it is more difficult and time consuming for stockholders to replace a majority of the directors on a classified board. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>No

election of directors. Cumulative voting allows a stockholder to vote a portion or all of its shares for one or more candidates for seats on the board of directors. Without cumulative voting, a minority stockholder may not be able to gain as many
seats on our board of directors as the stockholder would be able to gain if cumulative voting were permitted. The absence of cumulative voting makes it more difficult for a minority stockholder to gain a seat on our board of directors to influence
our board&#146;s decision regarding a takeover. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>Amendment of Charter and Bylaws Provisions </I></B></P>

An interested stockholder is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation&#146;s outstanding voting stock. We
expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We anticipate that Section&nbsp;203 may also discourage attempts that might result in a premium
over the market price for the shares of common stock held by stockholders. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The provisions of Delaware law and the provisions of our amended and restated

fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions might also have the effect of preventing changes in our management. It is possible that these provisions could
make it more difficult to accomplish transactions that stockholders might otherwise deem to be in their best interests. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Listing </B></P>
