<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">We are <FONT STYLE="color: #231F20">steadfastly
opposed to the illegal importation of non-human primates that are not purpose-bred into the United States. In furtherance of that objective,
we are committed to dedicating our resources to collaborate with the U.S. government and our industry partners to develop and implement
additional procedures to reasonably ensure the non-human primates we import are purpose-bred in accordance with applicable laws.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">We are committed to ongoing engagement with our
shareholders and every year reach out to, at a minimum, our 25 largest shareholders (generally reflecting shareholders holding more than
50% of our outstanding stock) to ask for their perspectives. From our most recent engagements, it became clear that shareholders would
appreciate and benefit from additional disclosure about our non-human primate importation practices to better understand how we are managing
related risks. In response to the feedback, starting in 2024, we intend to provide shareholders with an annual report from our Board describing
the efforts we are taking to reinforce confidence that the non-human primates we import are purpose-bred in accordance with applicable
laws.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Development of the additional procedures in collaboration
with the U.S. government and our industry partners is an on-going process. However, understanding that shareholders have an interest in
our disclosure intentions, we want to be clear and transparent that the development of this annual report will involve consultation with
the Company&rsquo;s shareholders to ensure that shareholder voices are heard, their feedback is carefully evaluated, and their concerns
are reflected in the development of the report. We plan to actively engage with our shareholders for input as to what content would be
most valuable. From a preliminary perspective, some examples of report content to be considered (and which we will discuss during our
future shareholder outreach) include:</P>
