                                                                       ---------

         ICAHN CONFIRMS INTENTION TO NOMINATE THREE DIRECTORS AT BIOGEN

NEW YORK, NEW YORK,  JANUARY 28, 2008 - Carl Icahn confirmed today that entities
affiliated  with him have  given  notice  to Biogen  Idec  that  they  intend to
nominate  three  persons  at  Biogen's   forthcoming   2008  Annual  Meeting  of
Stockholders to serve as directors of Biogen.  Biogen  currently has a staggered
board of twelve directors, and there are four directorships up for election this
year.

Mr.  Icahn  stated  that "we are taking  this  action  because  we believe  that
Biogen's recent purported attempt to find a suitor was not conducted in a way to
enhance the success of the endeavor. We believe that the process was flawed in a
number of key  respects  and that the  process  was run to  placate us and other
large shareholders who we believe asked for Biogen to find a buyer.

"It has been  reported in the press(1)  that Biogen  refused to allow  potential
bidders  to  talk  to  Elan   Pharmaceuticals,   Biogen's  partner  on  the  key
pharmaceutical  product  Tysabri.  Elan has  some  change-of-control  rights  on
Tysabri.   Although   Elan  has   indicated   that   they   would   not   invoke
change-of-control  rights,  obviously, any prospective bidder would want to talk
to Elan directly  about  change-of-control  issues as well as discuss the growth
trajectory for Tysabri. Incredibly,  Biogen prevented any bidder from talking to
Elan about  anything  unless they made a 'binding  proposal'  as reported in the
Financial Times on January 21, 2008."

Mr. Icahn also stated "We also believe that the confidentiality agreement was so
restrictive that certain  potential  bidders were not able to sign the agreement
and  therefore  were not able to  participate  in the  bidding."

Mr. Icahn also pointed out that after  Biogen  announced  that it was ending the
sale process,  Jim Mullen,  CEO of Biogen,  was quoted in the Financial Times as
saying that Biogen might make a large scale acquisition. He is quoted as saying,
"We could spend 10 billion  dollars."(2)  Mr. Icahn  indicated  that he is quite
concerned  and  believes all Biogen  shareholders  should share his concern that
Biogen  may  attempt  to make  an  acquisition  for the  purpose  of  making  it
unattractive  to, or reducing the number of, future potential  buyers.  In fact,
Mr. Icahn noted that the Times of London reported on Saturday that Biogen may be
considering a bid for a European biotech company (3). Mr. Icahn stressed that he
reserved the right to oppose any "toxic" transactions by all available means.

The slate of directors to be nominated by Mr. Icahn and his affiliates  consists
of  Alexander  J. Denner  whose  principal  occupation  is Managing  Director of
entities controlled by Mr. Icahn that manage private investment funds, Professor
Anne B. Young,  who is Julianne Dorn  Professor of Neurology at Harvard  Medical
School and  Chief,  Neurology  Service at  Massachusetts  General  Hospital, and
Professor  Richard C.  Mulligan,  who is  Mallinckrodt  Professor of Genetics at
Harvard Medical School, and Director of the Harvard Gene Therapy Initiative.

"We  determined  to run a slate of three  directors  to ensure that if the slate
were to be elected and Biogen's  management failed to act to enhance shareholder
value, shareholders would have the opportunity to elect sufficient new directors
in 2009 who,  together  with our slate of 2008  directors,  would  constitute  a
majority of the board."

     Icahn  Partners,  Icahn Master,  Icahn Master II, Icahn Master III and High
River  (collectively,  the "Icahn  Parties") are entities  controlled by Carl C.
Icahn.  Dr.  Denner is an  employee  and/or  officer  and  director of the Icahn
Parties  and  various  other  entities  controlled  by Mr.  Icahn  who may  also
participate in soliciting proxies from Biogen stockholders.  Dr. Denner does not
own beneficially any interest in securities of Biogen,  and will not receive any
special  compensation in connection with such  solicitation.  In connection with
his employment by Mr. Icahn and his  affiliated  companies,  Dr.  Denner,  among
other employees, has a participatory interest in the profits and fees derived by
Mr. Icahn and/or his  affiliated  entities  from Icahn  Partners,  Icahn Master,
Icahn Master II and Icahn Master III (collectively, the "Funds"). Because only a
portion  of such  profit  interests  are  distributed  and  because of his other
investments in the Funds,  Dr. Denner also has capital accounts in the Funds. In
the aggregate:  Dr. Denner's profit  interests and capital accounts in the Funds
entitle him to less than 2% of the profits generated by the Funds.

in the election of directors at the Biogen 2008 Annual  Meeting of  Stockholders

each of Dr. Young and Professor Mulligan a fee of $25,000.
