Revoking a Proxy. If you give your proxy pursuant to this solicitation, you may revoke it at any time prior to the Annual Meeting. You may revoke a previously provided proxy by: (i) delivering to our Corporate Secretary a written revocation of proxy; (ii) executing a new proxy that bears a later date; or (iii) participating in the Annual Meeting and voting your shares online at the Annual Meeting. Attendance at the Annual Meeting virtually will not, by itself, result in revoking a proxy. You should also be aware that if you are a beneficial owner, meaning that your shares of USANA common stock are held of record in an account by a broker, bank, trustee, or other nominee, and you wish to revoke a proxy or change your vote, you must contact the broker, bank, trustee, or other nominee to revoke any prior voting instructions and provide new voting instructions.
