<p style=""><span style="font-size: 11pt;"><br>
</span></p>
<p style=""><span style="font-size: 11pt;">Another supply chain story here. Honeywell has informed us that the </span><span style="font-size: 11pt;">MST sensors that we had ordered in April 2021 and were supposed to be delivered earlier in March of this year
won't be ready until early 2023. </span><span style="color: rgb(0, 0, 0); font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 11pt;">All
our gas sensors (NH3, Cl2, SiH4, HCl) are due for replacement, and we are currently concerned about the risk of running possibly expired sensors.</span><span style="font-size: 11pt;"> Anyone facing the same issue? Are there other reliable suppliers we can
purchase these sensors from? Any advice is </span>appreciated!<span style="font-size: 11pt;"> </span></p>
