A personalised proxy form is enclosed for convenience with this letter. The Company will also live video stream the Meeting for those shareholders who choose not to or are unable to attend the Meeting in person.

If you would like to view the live stream, please register your interest via email to meetings@vrxsilica.com. Questions from shareholders who plan not to attend the Meeting in person must be submitted in advance of the Meeting.
