Under the Tax Act, the historical exception under Section 162(m) of the Internal Revenue Code (the &#8220;</font><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Code</font><font style="font-family:inherit;font-size:10pt;">&#8221;) for qualified performance-based compensation and commissions was eliminated, effective January 1, 2018. Accordingly, all compensation that the Company may pay to a covered employee, as defined in Section 162(m) of the Code, in excess of $1 million is no longer deductible, including post-termination and post-death payments, severance, deferred compensation and payments from nonqualified plans. Due to the impact of the Tax Act on Section 162(m) of the Code, the statements in Proposal 3 of our definitive Proxy Statement regarding our ability to deduct compensation in excess of $1,000,000 should not be relied upon in deciding how to vote. Additionally, similar statements elsewhere in the Proxy Statement concerning our ability to deduct compensation pursuant to Section 162(m) of the Code, while relevant for tax years ending prior to the effective date of the Tax Act, are no longer applicable to us. As such, the disclosure in this Supplement supersedes statements in the Proxy Statement concerning the deductibility of performance-based compensation pursuant to Section 162(m) of the Code.</font></div><div style="line-height:120%;text-align:left;text-indent:33px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;text-indent:33px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">As our Board of Directors continues to believe that the number of shares currently available for issuance under the 2016 Plan is not sufficient in view of our compensation structure and strategy and that the availability of the additional shares sought in Proposal 3 will ensure that we continue to have a sufficient number of shares of common stock authorized for issuance under the 2016 Plan, the Board recommends a vote in favor of this proposal. However, in light of the Tax Act, a vote in favor of Proposal 3 is no longer required for purposes of amending and restating the performance goals set forth in the 2016 Plan to allow us to deduct performance-based compensation in accordance with Section 162(m) of the Code. Accordingly, Proposal 3 is hereby amended to delete the references to amending and restating the performance goals and to the Company&#8217;s ability to deduct performance-based compensation under Section 162(m) of the Code or otherwise to allow us to comply with the performance-based exception under Section 162(m). As amended, Proposal 3 shall only seek the vote of our shareholders to increase the number of shares of common stock reserved for issuance pursuant to awards granted under the 2016 Plan by 1,500,000 shares to an aggregate of 2,500,000 shares. Further, we are not seeking shareholder re-approval of the performance goals included in the 2016 Plan and no changes will be made to such performance goals.</font></div><div style="line-height:120%;text-align:left;text-indent:33px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;text-indent:33px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">However, </font><font style="font-family:inherit;font-size:10pt;background-color:#ffffff;">the</font><font style="font-family:inherit;font-size:10pt;">&#32;Company has not elected to amend the provisions of the 2016 Plan that were designed to provide for compliance with Section 162(m) of the Code.

However, to the extent that the Company issues such awards, it will no longer be entitled to an associated compensation deduction in excess of $1,000,000, as explained above.   </font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">&#160;</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div><br></div><div><div style="line-height:120%;text-align:left;font-size:11pt;"><font style="font-family:inherit;font-size:8pt;">{N0172291 4 }</font><font style="font-family:inherit;font-size:11pt;">&#160;&#160;&#160;&#160; </font></div><div style="line-height:120%;text-align:left;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br></font></div></div><hr style="page-break-after:always"><div></div><div><br></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Vote Required and Board Recommendation</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The affirmative vote of the holders of a majority of the votes cast at the annual meeting is required for the approval of Proposal 3.&#160;</font><font style="font-family:inherit;font-size:10pt;font-weight:bold;">The Board of Directors recommends that you vote&#160;</font><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">FOR </font><font style="font-family:inherit;font-size:10pt;font-weight:bold;">the approval of Proposal No. 3.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Additional Information &#8211; Voting; Proxies; Right to Revoke</font></div><div style="line-height:120%;text-align:left;text-indent:33px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;text-indent:33px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">If you have already returned your proxy card or voting instruction card or voted over the Internet or by telephone, you do not need to vote again unless you wish to change your vote.
