<div align='center'>IMPORTANT INFORMATION REGARDING DELIVERY OF PROXY MATERIALS</div>

Under the SEC rules, a company may select either of the following options for making proxy materials available to its stockholders:

| ● | the                                                                                     
 full set delivery option; or                                                            |
| ● | the                                                                                     
 option often referred to as the “notice and access” option or the “notice-only” option. |

A company may use a single method for all of its stockholders or use full set delivery for some while adopting the notice-only option for others.

Full set delivery option

Under the full set delivery option, a company delivers all proxy materials to its stockholders by mail. In addition to delivery of proxy materials to stockholders, a company must post all proxy materials on a publicly accessible website and provide information to stockholders about how to access the website. In connection with the Annual Meeting, we have elected to use the full set delivery option.Accordingly, you will receive all proxy materials by mail.

Notice-onlyoption

Under the notice-only option, which we have elected NOTto use for the Annual Meeting, a company must post all proxy materials on a publicly-accessible website. Instead of delivering proxy materials to its stockholders, a company may deliver a notice of Internet availability of proxy materials, which includes, among other things:

| ● | information                                                                                                              
 regarding the date and time of the annual meeting of stockholders, as well as the items to be considered at the meeting; |
| ● | information                                                                                                              
 regarding the website where the proxy materials are posted; and                                                          |
| ● | various                                                                                                                  
 means by which a stockholder can request paper or e-mail copies of the proxy materials.                                  |

If a stockholder requests paper copies of the proxy materials, these materials must be sent to the stockholder within three business days and by first class mail.

Use the notice and access option in the future

Although we have elected to use the full set delivery option in connection with the Annual Meeting, we may choose to use the notice-only option in the future. By reducing the amount of materials that a company needs to print and
