Quorum Requirement

The purpose of this letter is to provide new information
about the quorum requirement for the Special Meeting. On October 7, 2025, our Board of Directors adopted resolutions to amend our Bylaws
to provide that the holders of 33 and 1/3% of the outstanding shares of Common Stock will constitute a quorum at all meetings of our stockholders
for the transaction of business (the “Bylaw Amendment”), including at the Special Meeting. Our Bylaws previously provided
that the holders of a majority of the outstanding shares of stock constituted a quorum at all meetings of our stockholders for the transaction
of business. By reducing the quorum requirement from a majority of outstanding stock to 33 and 1/3% of outstanding stock, we are more
likely to reach quorum and hold a valid stockholders meeting. In particular, our Board of Directors believes that there are important
proposals to be considered by stockholders at the Special Meeting including, but not limited to, an increase in authorized shares. If
a quorum cannot be obtained, no action can be taken on these matters, and the Company would be obligated to incur the expense of calling
and holding another meeting of its stockholders. Moreover, the Board believes that the new quorum requirement is high enough to ensure
that a broad range of stockholders are represented at meetings, while also reducing the risk of the Company needing to adjourn such meetings.

Supplemental Disclosures to the Proxy Statement

The following Q&A from page 3 of the Proxy
Statement is amended to read as follows:

Q: What constitutes a quorum?

A: The holders of one-third of the 40,859,307
shares of Common Stock outstanding as of the Record Date, either present by remote communication or represented by proxy, constitutes
a quorum. A quorum is necessary to conduct the Special Meeting. If you sign and return your paper proxy card or authorize a proxy to vote
electronically or telephonically, your shares will be counted to determine whether we have a quorum even if you abstain or fail to vote
as indicated in the proxy materials. Broker non-votes and abstentions will be counted as present for the purpose of establishing a quorum.
If a quorum is not present by attendance at the Special Meeting or represented by proxy, the chairman of the meeting or the stockholders
present by attendance at the meeting or by proxy may adjourn the
