(the &#8220;Company&#8221;) filed a Certificate of Amendment to the Amended and Restated Certificate of Incorporation of the Company, as amended (the &#8220;Amendment&#8221;), to implement a seven-for-one reverse split of its common stock (the &#8220;Reverse Split&#8221;), as previously authorized and approved at the Company&#8217;s annual meeting of stockholders on June 22, 2015. The Reverse Split will be effective as of 5:01&#160;p.m. (Eastern Time) on September 3, 2015, and the Company&#8217;s common stock will continue trading on the Nasdaq Capital Market on a post-split basis on September 4, 2015. </p>
<p style="margin-bottom:0pt;margin-top:9pt;text-indent:0%;font-size:10pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">As a result of the Reverse Split, every seven shares of issued and outstanding common stock will be combined into one share of issued and outstanding common stock. In addition, the Reverse Split will effect a proportionate adjustment to the per share exercise price and the number of shares issuable upon the exercise or settlement of all outstanding options and warrants to purchase shares of the Company&#8217;s common stock, and the number of shares reserved for issuance pursuant to the Company&#8217;s existing stock option plans will be reduced proportionately. No fractional shares will be issued as a result of the Reverse Split, and stockholders who otherwise would be entitled to a fractional share will receive, in lieu thereof, a cash payment based on the closing sale price of the Company&#8217;s common stock as reported on the Nasdaq Capital Market on September 3, 2015. Because the Amendment does not reduce the number of authorized shares of the Company&#8217;s common stock, the effect of the Amendment will be to increase the number of shares of common stock available for issuance relative to the number of shares issued and outstanding.&#160;The Reverse Split will not alter the par value of the Company&#8217;s common stock or modify any voting rights or other terms of the common stock. </p>
