Clinton Group Responds To Latest Misleading Statements from Stillwater Mining

NEW YORK, May 1, 2013

Clinton noted that it has made multiple, specific proposals for settlement of the proxy contest all of which would have resulted in the Clinton nominees having less than a majority of the board, continuity of directors and institutional knowledge and the appointment of new, unaffiliated directors who were suggested by large Stillwater stockholders. The Company has seemingly accepted several of these offers, only to later renege on those seemingly accepted agreements later.

Most recently, Stillwater has been unavailable for more than 24 hours to discuss a settlement and made a vague offer less than 5 minutes before the Clinton principals were, as the Company knew, scheduled to board planes to attend the annual meeting in a remote part of Montana. Within 30 minutes of the plane departing, Stillwater put out a press release, knowing the Clinton team could not easily respond.

The latest Company proposal was clearly unworkable-providing for a four-four deadlocked board, with the incumbent contingent continuing to be dominated by Frank McAllister, who would remain in place as CEO for an indefinite period.  Given that one of the Company's directors told Clinton representatives this morning that Mr. McAllister has been "manipulating" the Company's directors in an effort to ensure his continued role as CEO and that he has no willingness to step aside as CEO or accept a proposal that threatens his control of the board or his CEO job, Clinton does not believe the proposed, deadlocked board is in the interest of stockholders.

Clinton remains willing to settle the proxy fight on a reasonable basis that involves a substantial change in the composition of the board and a cohesive group of directors who are agreed upon the general strategic direction of the business. Given the overwhelming support the Clinton nominees have received from Stillwater stockholders, Clinton does not believe the Company's stockholders desire a deadlocked board with no clear agreement on strategy or company leadership.
