This year, our annual meeting is scheduled to be held on June 29 and our shareholders are being asked to elect seven directors.</font><font style="color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:11.0pt;font-family:&quot;Calibri&quot;, sans-serif;min-width:fit-content;">  </font></p>

In addition to the nominees recommended for election by our Board, one of the company&#x2019;s shareholders, Sarissa Capital (Sarissa), nominated three candidates for election. Sarissa&#x2019;s motivation for nominating directors is unclear. Regardless, as a matter of good practice, our Board interviewed and evaluated the three Sarissa candidates and determined that their skills were not additive to those already represented on our Board. For these and other reasons, our Board recommended that our shareholders vote against the Sarissa candidates.</font><font style="color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:11.0pt;font-family:&quot;Calibri&quot;, sans-serif;min-width:fit-content;"> </font></p>
