Policy on Stockholder Communications with Directors

The Board has established a process to receive communications from stockholders and other interested parties. Stockholders and other interested parties may contact any member (or all members) of the Board (including without limitation the lead independent director, Patrick M. James, or the non-management directors as a group), any Board committee or any chair of any such committee by mail or electronically. To communicate with the Board of Directors, any individual directors or any group or committee of directors, correspondence should be addressed to the Board of Directors or any such individual directors or group or committee of directors by either name or title. All such correspondence should be sent to the Corporate Secretary, Stillwater Mining Company, P.O. Box 1330 536 East Pike Avenue Columbus, Montana 59019. To communicate with any of our directors electronically, stockholders should scroll down on this page. You will find an online form that may be used for writing an electronic message to the Board, any individual directors, or any group or committee of directors. Please follow the instructions on our website in order to send your message.

All communications received as set forth in the preceding paragraph will be opened by the office of our General Counsel for the sole purpose of determining whether the contents represent a message to our directors. Any contents that are not in the nature of advertising, promotions of a product or service, or patently offensive material will be forwarded promptly to the addressee. In the case of communications to the Board or any group or committee of directors, the General Counsel’s office will make sufficient copies of the contents to send to each director who is a member of the group or committee to which the envelope or e-mail is addressed.
