                                                                      Exhibit 1

                              FOR IMMEDIATE RELEASE
                          ICAHN UNIT COMMENTS ON MYLAN

New York, New York, July 18, 2005
Contact:  Susan Gordon (212) 702-4309

         On July 26,  2004,  Mylan  announced  its  intention  to  acquire  King
Pharmaceuticals.  Thereafter,  Mylan  stock  traded as low as $14.69  per share.
Following that announcement, Mr. Icahn became involved in Mylan as a shareholder
activist  and,  among  other  things,  strongly  criticized  the  proposed  King
acquisition  as   "reprehensible"   and  not  in  the  best  interest  of  Mylan
shareholders. Mr. Icahn also announced his intention to conduct a proxy fight at
Mylan.

         Since Icahn's involvement as a shareholder activist and vocal critic of
the Mylan Board and management,  Mylan has: (i) abandoned the King  transaction;
(ii)  announced  the $1.25 billion  share  buy-back;  (iii) doubled its dividend
rate; (iv) taken steps to exploit Nebivolol through a major distribution partner
and (v) announced the  retirement of two of its  non-independent  directors.  On
July 15, 2005,  the  expiration  date of the Mylan tender  offer,  Mylan's stock
closed at $19.40,  an increase of 32% from the time of Mr. Icahn's  involvement.
Mr. Icahn  stated:  "There is no question that  shareholder  activism has worked
well to enhance shareholder value at Mylan."

         Icahn  affiliate  High River Limited  Partnership  tendered 26,291,200
shares  of  Mylan  common  stock  pursuant  to  the  Mylan  tender  offer.   The
determination  to tender was made late on July 15, following the announcement by
the FDA regarding  Mylan's generic Duragesic  product,  with no clarification or
further comment from Mylan.  High River's  determination  to tender was based on
careful  consideration of the above factor,  and, among other things, its belief
that it would be  difficult  to win a proxy fight with the stock  trading at the
current  levels.  As previously  stated,  Mr. Icahn did not wish to be a passive
investor in this company.

         Mr. Icahn is still of the belief that shareholder value will be further
enhanced if Mylan were put up for sale and  consolidated  with a larger company.
At this time, the determination  whether or not Icahn will conduct a proxy fight
at Mylan will be  dependent,  for the most part,  on the price at which  Mylan's
stock  trades over the next several  weeks,  the actions of  management  and the
views of large Mylan shareholders.
