                CARL ICAHN ISSUES OPEN LETTER TO SHAREHOLDERS OF
                              OSHKOSH CORPORATION

New York, New York, January 11, 2012
Contact: Susan Gordon (212) 702-4309

Carl Icahn today issued the following open letter to shareholders of Oshkosh
Corporation:

                                 Carl C. Icahn

                                                         January 11, 2012
Dear Fellow Oshkosh Shareholders:

     On January 9, 2012 Oshkosh put out an investor presentation indicating that
I  have  a  "mixed"  track  record  of  delivering  value to shareholders. In my
opinion,  this  presentation  is  a  complete  misstatement  of  the facts and a
transparent  attempt to divert attention away from the real issues in this proxy
contest.

     I  believe  my  investment  track  record  speaks for itself and have never
thought  it  needed  to  be  defended  in a public proxy contest. However, since
Oshkosh  chose  to bring up my record, I will make the following brief comments.

     Oshkosh  conjured  up  a  list  of  subject  companies  that they purported
measured  my  track  record.  Much  of  the information they present is not only
inaccurate  but  they  fail  to include on their list many of my most successful
investments,  such  as  ImClone, Biogen, Genzyme, Motorola Mobility, Kerr-McGee,
BEA  Systems,  Medimmune,  Fairmont Hotels and Chesapeake Energy, to name only a
few.

     Over  the last five years, my investment funds have achieved a gross return
of  nearly  50%,  compared  to a negative 1.2% return in that period for the S&P
500.  Meanwhile,  over  the  last  five  years, the Oshkosh board has overseen a
decline  in  the  Oshkosh  share  price of more than 55% and a loss of over $4.3
billion  of  total enterprise value, despite landing a lucrative M-ATV contract,
which  is  now  at  the  end  of  its production cycle. In addition, in 2011, my
investment funds were up 35%, or approximately $1.9 billion, which is nearly the
entire  market capitalization of Oshkosh, while the Oshkosh share price declined
nearly  40%  and  performed  worse  than  all 16 companies they mention in their
presentation  as  their  peers.  But  perhaps  more  importantly,  much  of  our
investment  record is due to the fact that we had a minority position on many of
the  boards of the companies in which we were invested. Examples of these, among
others,  are  Biogen, Genzyme, Motorola, Yahoo, Mentor Graphics, Hain Celestial,
and  Take-Two.  As  minority  representatives on these boards, we fought for and
helped  to  expedite positive changes which enhanced value for all shareholders.

     I hope you, the Oshkosh shareholders, will give my nominees the opportunity
to  achieve  the  same  results  for Oshkosh that my various nominees and I have
produced  at  the  companies  mentioned  above.

Sincerely,

/s/ Carl Icahn
