 to ensure that all of your shares are voted. We strongly recommend that you vote your shares in advance of the meeting as instructed above, even if you plan to attend the Annual Meeting virtually. Expenses of Soliciting Proxies We will pay the expenses of soliciting proxies, including preparation, assembly, printing and mailing of this Proxy Statement, the proxy and any other information furnished to stockholders. Following the original mailing of the soliciting materials, we and our agents, including directors, officers, and other employees, without additional compensation, may solicit proxies by mail, email, telephone, facsimile, by other similar means or in person. Following the original mailing of the soliciting materials, we will request brokers, custodians, nominees and other record holders to forward copies of the soliciting materials to persons for whom they hold shares and to request authority for the exercise of proxies. In such cases, we, upon the request of the record holders, will reimburse such holders for their reasonable expenses. If you choose to access the proxy materials or vote through the Internet, you are responsible for any Internet access charges you may incur. Revocability of Proxies A stockholder of record who has given a proxy may revoke it at any time before it is exercised at the Annual Meeting by:

| • | delivering to our Secretary by mail a written notice stating that the proxy is revoked; |

| • | signing and delivering a proxy bearing a later date; |

| • | voting again through the Internet; or |

| • | attending and voting at the Annual Meeting (although attendance at the Annual Meeting will not, by itself, revoke a proxy). |

Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to revoke a proxy, you must contact that firm to revoke any prior voting instructions. Voting Results Voting results will be tabulated and certified by the inspector of elections appointed for the Annual Meeting. The preliminary voting results will be announced at the Annual Meeting. The final results will be tallied by the inspector of elections and filed with the SEC in a current report on Form 8-K within four business days of the Annual Meeting.
