Advance notice procedure

Our bylaws also establish an advance notice procedure
for stockholders who wish to present a proposal or nominate a director at an annual meeting, but do not seek to include the proposal
or director nominee in our proxy statement. In order to be properly brought before our 2026 annual meeting of stockholders under the
advance notice provisions of our bylaws, the stockholder must provide timely written notice that must be received by the Secretary at
the principal executive offices of the Company, and any such proposal or nomination must constitute a proper matter for stockholder action.
The written notice must contain the information specified in our bylaws. To be timely, a stockholder’s written notice must be received
by the Secretary at the principal executive offices of the Company:

In the event that we hold our 2026 annual meeting
more than 30 days before or more than 30 days after the first anniversary of the 2025 annual meeting, then written notice required by
our bylaws must be received by the Secretary at the principal executive offices of the Company:
