Voting Before the Meeting

To vote your shares before the Annual Meeting, please follow the instructions for Internet or telephone voting provided on the Notice. If you request printed copies of the proxy materials by mail, you may also vote by signing and submitting your proxy card and returning it by mail, if you are the stockholder of record, or by signing the voter instruction form provided by your bank or broker and returning it by mail, if you are the beneficial owner but not the stockholder of record. We encourage you to vote before the Annual Meeting even if you plan to attend the Annual Meeting to ensure that your shares will be represented whether or not you are able to attend the meeting.

Voting at the Meeting

Stockholders may vote and ask questions during the virtual Annual Meeting. To participate in the Annual Meeting, you will need to log into the virtual meeting website with your individual control number provided on your proxy materials. However, even if you plan to attend the Annual Meeting, we recommend that you vote your shares in advance, so that your vote will be counted if you later decide not to attend the Annual Meeting.

Street Name Holders

If you are a beneficial owner who holds your shares in street name, you have the right to direct your broker on how to vote the shares held in your account. You should follow the instructions in the Notice or voting instructions provided to you by that organization to vote your shares or direct the organization on how to vote your shares.
