• voting online at the Annual Meeting, as described in the “How to Vote” section above; or

• filing a written revocation with our corporate secretary.

If your shares are held in “street name,” you may submit new voting instructions by contacting your bank, broker or other nominee holding your account. You may also vote online at the Annual Meeting, which will have the effect of revoking any previously submitted voting instructions, if you obtain a legal proxy from the organization that holds your shares as described in the “How to Vote” section above.

Your virtual attendance at the Annual Meeting will not automatically revoke your proxy, unless you vote online during the Annual Meeting.

#### Costs of Proxy Solicitation
We will bear the costs of soliciting proxies. In addition to solicitations by mail, our directors, officers and regular employees, without additional remuneration, may solicit proxies by telephone, facsimile, email, personal interviews and other means.

### Voting Results
We plan to announce preliminary voting results at the Annual Meeting and will publish final results in a Current Report on Form 8-K to be filed with the SEC within four business days following the Annual Meeting.
