To Our Fellow Stockholders of the Stillwater Mining Company:

Clinton Group and funds it manages are stockholders of Stillwater Mining
Company ("Stillwater" or the "Company").

I am writing again to encourage you to join us in seeking a better future for
Stillwater by changing the composition of the Company's Board of Directors.
With the Annual Meeting of stockholders approaching quickly, I encourage you
to use the enclosed GREEN proxy card to vote for change. More information
about our nominees and our views about the Company can be found at
http://www.TapStillwater.com.

The sitting Board of Directors has made many value destructive mistakes. They
decided to "diversify" the Company away from being the only US-based,
pure-play platinum group metals ("PGM") company in the world. They did so by
buying two companies, each for premiums exceeding 250%: one in Canada and one
in Argentina. Neither acquisition went well. The management team is no longer
certain that the Canadian property can be economically developed into a mine
and Stillwater's CEO recently admitted he would not buy the Argentina mining
rights again, if he had the choice. But the $525 million of stockholder
capital that was spent is gone, and the damage to Stillwater's stock price,
reputation and attractiveness as an investment is, sadly, still with us.

Back in Montana, where the crown jewel assets are, costs are exploding in
every direction: more CEO pay, more Board pay, more marketing spend, more
overhead, more people and more financing costs. Of course, one thing has
stayed stubbornly flat: the number of ounces produced by the Company has not
budged significantly in the 12 year tenure of the current CEO, despite more
than $1 billion in capital expenditures.

The Board now claims it is going to focus on the Montana assets and not be
distracted by a desire to build, as the Company called itself, a "mid-cap
diversified mining Company." This is a convenient change in heart and one we
do not credit. Moreover, we cannot help but note:

  oJust five months ago, in its Third Quarter report, the Company said it was
    still searching "around the world" for acquisitions;
  oIn November 2012, the Board added a director, George Bee, who was profiled
    in a Canadian Mining Journal article entitled, "Passionate About South
    America," in which he extols the virtues of mining in South America and
    notes his desire to "return to San Juan, Argentina," the precise place
    where Stillwater purchased mining rights its CEO now supposedly regrets;
  oIn the last 30 months, fully 71% of the Company's expansion capital
    (acquisitions and capital expenditures) have been spent outside of
    Montana; and
  oThe Company's CEO resides, according to his voter registration records, in
    a small town in Nevada, more than 900 miles from the Company's mine and
    headquarters. [1]

Color us unconvinced that the Board is "focused" on Montana. We suspect as
soon as this proxy fight is over, if the incumbents are still in the Board
room, so too will be two things that should make all Stillwater stockholders
shudder: a map of the world and a checkbook.

As if this were not enough, the CEO was recently forced to return $2.3 million
of compensation that was granted to him by the Board in violation of the
Company's stockholder-approved equity compensation plan in three different
years. The return of the improper compensation only happened after a
stockholder sued the board members personally for the waste of stockholder
assets. Even so, the Board has refused to admit it was wrong in approving
grants in excess of the stock plan's explicit limitations and maintains that
it indeed has the continuing authority to ignore completely compensation
limits approved by stockholders. Brash. It appears with this Board in place,
stockholders will need to be forever vigilant or risk even more dissipation of
their capital.

Wouldn't it be better to have a Board in place that was dedicated to, and
respected, stockholders?

That is why we have nominated an outstanding group of professionals capable of
reversing the mistakes of the past and of guiding the Company more
thoughtfully in the future. If elected, stockholders will not need to fear
another strategic diversion, or an ill-conceived acquisition, or an
acquisition with improper diligence, or an acquisition in a country run by a
despot, or wasted marketing expenditures, or bloating overhead costs, or
violations of the Company's equity plans, or inefficient corporate financing
transactions. Perhaps most importantly, stockholders will know that every new
project – such as the development of the Marathon project in Canada – will be
reviewed objectively without the incentive to cover-up prior diligence
mistakes with rosy projections and the expenditure of significant additional
dollars.

The Stillwater Board has finally decided it will attempt to defend a portion
of its track record. In a recent presentation, it claims that if stockholders
ignore two years of Mr. McAllister's tenure, Mr. McAllister has matched the
PGM basket price with stock performance. (Meanwhile, of course, the Company
gives our nominee, Charles Engles, no credit for the significant price
appreciation and even more substantial out-performance relative to the basket
price during his entire CEO tenure at the Company.) But, you can claim
anything with a stock chart when you get to cherry pick the starting and
ending dates. We see no reason why Mr. McAllister should get a two-year free
pass on his performance.

The Company also now claims that it has an "exceptional cost containment
record." Meanwhile, cash costs associated with mining PGMs have increased from
$422 per ounce in 2011 to a projected $560 in 2013, an increase of 32% in just
two years. [2] On the G&A side, the Board is quick to "adjust" away for
purposes of its analysis more than 25% of the actual cash costs it incurs as
being "inappropriate" for measuring the costs of the business; the Board
ignores, for example, all of the ongoing operating costs it agreed to take on
when it acquired Marathon and Peregrine. Even with the Board's adjustments,
there is a 17% increase in G&A from 2010 to 2012 while production is up just
3%.

More telling are the things the Board does not even attempt to justify in its
new 12-page presentation. The Board does not ever say that its selection of a
convertible bond for financing in October 2012 was the right approach. How
could it? A non-convertible, high-yield bond would have been less expensive to
the Company if the Board believed the common stock price would appreciate at
least 8.5% per year during the seven years after the financing. [3] In other
words, to justify the convert, the Board must have a dour view of the stock,
the Board's ability to create value for stockholders and the Company's
prospects. No wonder the Board has not attempted to justify the financing. But
make no mistake: we are bullish on the Company and our nominees are confident
of their ability to create value for stockholders. We would not therefore have
done a financing that works best if the stock stays flat or increases only
modestly.

The words "Marathon" and "Peregrine" – the two value-destructive acquisitions
the incumbent Board approved – are not even mentioned in its 12-page slide
deck, which supposedly responds to our complaints. No comment from the Board
on its decision to pay a 259% premium for Marathon PGM, an acquisition that
was completed after faulty diligence, or on its decision to pay a 290% premium
for Peregrine Metals, an acquisition the CEO says he regrets. In the last ten
years, there have only been four acquisitions by US public companies with an
acquisition premium over 250%. Our beloved Company, Stillwater, did two of
them. [4] One could only justify such a premium if there were identified,
significant cost savings in a combination; no such opportunity even exists
here.

While it cannot justify betting against reasonable growth in the Company's
stock or spending the stockholders' precious capital on two large
ill-conceived acquisitions, the Board is willing to criticize us and attempt
to throw up dust about our nominees. Their latest foray into this dishonorable
territory is to disingenuously claim we have proposed various "inconsistent"
things that do not amount to a "solid business plan." We encourage
stockholders to read our presentation (available on www.TapStillwater.com) and
decide for themselves. We believe we have laid out a course forward for the
Company that will lead to the creation of significant stockholder value by
focusing on the Montana assets. We are objective and prepared to reevaluate
openly the Company's past corporate finance, capital allocation and
acquisition strategies, among other things. We recognize we cannot go down
every possible path at once (and, of course, never suggested doing so), but we
are committed to analyzing them all carefully.

The Board also demands that Dr. Engles, one of our seven nominees explain why
he left the Stillwater CEO post more than 16 years ago. What I know is that
Dr. Engles was the founding visionary for Stillwater, the stock price
appreciated rapidly on his watch and that his integrity, intelligence, honesty
and commitment to the Company have been vouched for by every person who knew
him or worked with him at the Company with whom I have spoken, including many
of the former senior officers. I also know that three months after Dr. Engles
left the Company, stockholders successfully replaced three directors on the
Board who had opposed his efforts to complete the expansion plan and begin
early work on the East Boulder mine.

Stockholders should demand that the incumbent Board explain their track record
– all of it – before it attempts to cast aspersions on others. While it is
unlikely that the incumbent Board would again pay a 250% premium or bet
against the growth in their stock with a convertible bond offering, how much
confidence can we have that they will not make a similarly devastating
mistake? We respectfully suggest that a Board that has not dispatched its
responsibilities with distinction is unlikely to reform itself and do so in
the future.

We therefore believe that the incumbent Board needs to be replaced. Wholesale.
As stockholders, let's put in place a Board that has a mandate to refocus on
Montana, to hire a chief executive who will reside in and focus on Montana,
and who will cut costs, increase production, aim to generate returns for
stockholders and be paid well only when he or she does well for investors.

herewith. For more information, and regular updates, on our campaign to

[1] We note that his mailing address (for his Nevada property tax bill and
for his Nevada voter registration) is not a Montana address either. Rather,
Mr. McAllister receives mail at his wife's 7500 square foot house in Salt Lake
City, where we suspect Mr. McAllister spends some time also.

[2] The Company would have stockholders focus on its modest growth in cash
costs from 2008 to 2012 and says that the annualized growth rate is a mere 5%
during that period. But cash costs were extremely high in 2008, so the Board
is using the Company's poor 2008 performance as a favorable comparison to its
current costs. Through 2012, cash costs have grown annually more substantially
if measured against the cash costs in any year other than 2008: 2006 (9%),
2007 (8%), 2009 (10%), 2010 (10%) and 2011 (15%).

[3] Assumes a 20% tax rate (per the Company), a seven-year life because there
is a put/call feature at year seven, an 8% high-yield coupon (which was 63
basis points higher than the average high-yield transaction in Q42012), and a
starting stock price of $12.12, which was the closing price on October 10,
2013, the day before the transaction was priced.

with a purchase price of at least $60 million. The other two transactions were
