                             FOR IMMEDIATE RELEASE

                CARL ICAHN ISSUES OPEN LETTER TO SHAREHOLDERS OF
                              OSHKOSH CORPORATION

New  York,  New  York,  January  6,  2012
Contact:  Susan  Gordon  (212)  702-4309

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

Dear Fellow Oshkosh Shareholders,

The  Oshkosh  Annual Meeting will take place Friday, January 27, 2012. Your vote
is  important  as  Oshkosh  is  at a CRITICAL JUNCTURE and I believe that my six
director  nominees have the necessary skills, experience and objectivity to help
fix  the  problems  at  Oshkosh. I think CHANGE IS NECESSARY and crucial for the
future  success  of  Oshkosh.

In  a  recent  letter  from  the  Oshkosh Chairman and from the CEO, the company
argues that they should be supported due to a 3-year total shareholder return of
45%. I find this to be absurd since during this time period the total enterprise
value  of  Oshkosh decreased by approximately $500 million, from $3.1 billion to
$2.6  billion.(1)

Additionally, I am not sure why this management team feels that their past stock
performance is an attribute for which they are owed loyalty, considering Oshkosh
was  trading  at  $35  per  share at the start of 2011 and now trades in the low
$20s.  The  company is also one of the worst performing among its peers in terms
of  stock  performance  over the past five years, and the worst in terms of 2012
projected  earnings  growth.

The board feels that it is useful to list all of the actions they have taken "In
the  face  of  unprecedented market challenges" without mentioning their current
dire  situation in terms of falling profitability and low share price. They have
curiously  focused  on  items  that  are  old  news  such  as:

     -    "Achieved  the  #1  or  #2  brands  in virtually all of its markets" -
          though  this  has not changed for years and was primarily accomplished
          by  acquisitions.

     -    "Developed  innovative, profitable products like the M-ATV" - which is
          now  at  the  end  of  its  production  cycle.

     -    "Reduced  debt  by  approximately  $2  billion" - We believe this debt
          never  should  have  been  incurred in the first place. It was used to
          fund  the acquisition of a company whose earnings subsequently went to
          zero.  Management  then had to seek waivers under this debt to avoid a
          potentially  disastrous  default.  Management  is  now  asking  for
          shareholders  to  be  grateful  that  they  have  paid down this debt.

     -    "Cut  approximately  $200 million in costs in fiscal 2009" - IT IS NOW
          FISCAL  2012.

______________________
(1) Total enterprise value of approximately $3.1 billion as of December 31, 2008
is  based  on  total net debt of approximately $2.432 billion as of December 31,
2008  and  market  capitalization  of  approximately  $662 million (based on the
closing  stock  price  on  December  31,  2008).  Total  enterprise  value  of
approximately $2.6 billion as of December 31, 2011 is based on total net debt of
approximately  $631.5  million as of December 31, 2011 and market capitalization
of approximately $1.95 billion (based on the closing stock price on December 31,
2011).



I  believe  this  is one of the major problems with the incumbent management and
board;  they  are congratulating themselves for actions taken in the past rather
than  addressing  challenges  the  company  faces  in  the  present  and future.

The  board has suggested that I confirmed at a meeting with management that I do
not  understand the defense business. This only confirms my belief that they did
not  understand  me  in  the  first  place.  Irrespective  of  any  apparent
miscommunication,  there is one thing I do understand about the defense business
-  defense  contractors should charge their customers a price in excess of their
cost  which  is  a  concept that seems to me to be lost on the Oshkosh board and
management  given  the  recent  experience  with  the  FMTV  contract.

The  board is also alleging that I have provided no substantive ideas to enhance
shareholder  value. After reviewing the details surrounding the MOVE strategy, I
firmly  believe that their strategy provides no substantive ideas to proactively
enhance  shareholder value. To put it differently, I believe that their strategy
represents  the  same  "wait and see" approach to a recovery which the board has
been  implementing  for years. Shareholders deserve a real plan to deliver value
TODAY  centered  on  the  following:

     -    Immediately  explore  alternatives  for  JLG  to reallocate capital to
          debt  reduction,  returning  capital  to  shareholders  and  providing
          opportunities to pursue a more active acquisition strategy surrounding
          core  businesses.  -

     -    Capitalize  on  a  weak  economy  by  consolidating  existing  niche
          businesses  and  entering  new  synergistic  product lines rather than
          waiting  to  see  how  the  economy  progresses.

     -    Aggressively  seek  small acquisitions and joint venture opportunities
          in  core product areas to develop a comprehensive international growth
          strategy.

     -    Position  the  company  to  participate  in  coming  defense  industry
          consolidation  as  both  a  buyer  and/or  a  seller.

     -    Integrate  and  restructure  existing  operations  to  maintain
          profitability, and if the current management is not willing or capable
          of  executing  such  a  restructuring,  finding a management team that
          will.

I  believe  that  my  nominees  have  excellent  operational  and  financial
qualifications  and  that  their  experience  would  be  extremely beneficial to
Oshkosh  and  its shareholders to move this company to develop a value enhancing
strategy.

I  urge  shareholders  to  VOTE  THE GOLD CARD FOR ALAPONT, GUSTAFSON, INTRIERI,
KRONGARD,  MERKSAMER  AND NINIVAGGI to send a message to the company and deliver
the  necessary change to take Oshkosh into the future. If you have already voted
the  white  card,  you  can  still change your vote by now VOTING THE GOLD card.

Sincerely,

Carl C. Icahn
