                               -------------------

To Our Fellow Biogen Stockholders:

     This  Proxy  Statement  and the  accompanying  GOLD  proxy  card are  being
furnished to  stockholders  ("Stockholders")  of Biogen Idec Inc.  ("Biogen") in
connection with the  solicitation of proxies by Carl C. Icahn and certain of his
affiliates  and  associates,  to be used at the 2008 Annual Meeting (the "Annual
Meeting")  of  Stockholders  of Biogen  which is  scheduled to be held at ______
p.m.,        local       time,        on        ________,        2008,        at
___________________________________________________,  and at  any  adjournments,
postponements or continuations  thereof. This Proxy Statement and the GOLD proxy
card are first being furnished to Stockholders on or about April __, 2008.

     At the Annual Meeting,  the Participants (as hereinafter defined) will seek
to elect to the Board of Directors of Biogen - Dr. Alexander J. Denner, Dr. Anne
B. Young and Professor Richard C. Mulligan (each a "Nominee",  and collectively,
the "Nominees") who has each consented,  if elected, to serve as a director.  In
addition,  Biogen's  Amended and Restated  ByLaws (the  "Bylaws")  provide for a
three-class classified board, the size of which may be expanded by a vote of the
Board. In order to provide the Stockholders with the ability to elect a majority
of  Stockholder  nominated  directors  following  the 2009 annual  meeting,  the
Participants  will seek to amend the  ByLaws to fix the number of  directors  at
twelve. For example, if the Stockholders elect Dr. Alexander J. Denner, Dr. Anne
B. Young and  Professor  Richard  C.  Mulligan  to the Board at the 2008  Annual
Meeting, and in 2009, a Stockholder nominates,  and the Stockholders elect, four
director nominees at the 2009 annual meeting, then the Board would include seven
Stockholder nominated directors.  If the Bylaw Amendments (as defined below) are
adopted by the Stockholders at the 2008 Annual Meeting and the Board is fixed at
12 directors,  then those seven Stockholder nominated directors elected over the
course of two annual meetings would constitute a majority of the Board. However,
because the current  Bylaws allow the Board to expand the size of the Board,  if
the Bylaw  Amendments  are not adopted at the 2008 Annual  Meeting and the Board
decides to expand the size of the Board  (despite  the fact that such a decision
to expand the size of the Board  could  constitute  a breach of  fiduciary  duty
under applicable law), then those seven  Stockholder  nominated  directors would
merely  constitute a minority of the Board. As such, the Participants  will seek
to amend the Bylaws (collectively, the "Bylaw Amendments"):

     o    to replace the first  sentence  of Section  3.1 of the  Bylaws,  which
          reads:

               "The number of directors  that shall  constitute the entire Board
               initially  shall be  twelve  (12);  provided,  however,  that the
               number of directors that shall  constitute the entire Board shall
               be fixed from time to time by resolution adopted by a majority of
               the entire Board",

               in its entirety with the following sentence:

               "The number of directors  that shall  constitute the entire Board
               shall be twelve (12)."

     o    to delete,  in its entirety,  the first sentence of Section 3.2 of the
          Bylaws which reads:

               "The number of members of the Board may be  increased at any time
               as provided in Section 3.1 above."

     o    to  delete,   in  their   entirety,   the  words  "and  newly  created
          directorships  resulting from any increase in the authorized number of
          directors",  appearing  in the second  sentence  of Section 3.2 of the
          Bylaws which reads, in its entirety:

               "Sole power to fill  vacancies  and newly  created  directorships
               resulting from any increase in the authorized number of directors
               shall be vested in the Board,  and each  director so chosen shall
               hold office  until the next annual  election at which the term of
               the class to which they have been elected  expires and until such
               director's  successor is duly elected and qualified or until such
               director's  earlier  resignation,  removal from office,  death or
               incapacity."

     DR.  ALEXANDER  J.  DENNER,  DR.  ANNE B.  YOUNG AND  PROFESSOR  RICHARD C.
MULLIGAN URGE STOCKHOLDERS TO VOTE FOR EACH OF THEM AS DIRECTORS AND TO VOTE FOR
EACH OF THE BYLAW AMENDMENTS.

     The Nominees and each of the other  Participants have no interest in Biogen
other than through the beneficial  ownership (if any) of shares of Common Stock,
par value $.0005 per share,  of Biogen (the  "Shares") or other  securities  (if
any) of Biogen as disclosed herein,  and, in the case of Dr. Young and Professor
Mulligan,  pursuant to an agreement in which certain affiliates of Carl C. Icahn
have  agreed to pay each of Dr.  Young and  Professor  Mulligan  $25,000  and to
indemnify  each such Nominee with respect to certain costs incurred by each such
Nominee in connection with the proxy contest relating to the Annual Meeting (the
"Nominee Agreement").

     DR.  ALEXANDER  J.  DENNER,  DR.  ANNE B.  YOUNG AND  PROFESSOR  RICHARD C.
MULLIGAN ARE  COMMITTED TO ACTING IN THE BEST  INTEREST OF THE  STOCKHOLDERS  OF
BIOGEN.  WE URGE YOU TO VOTE YOUR GOLD PROXY CARD FOR DR.  ALEXANDER  J. DENNER,
DR. ANNE B. YOUNG AND  PROFESSOR  RICHARD C.  MULLIGAN AND FOR EACH OF THE BYLAW
AMENDMENTS.

entitle  him to less than 2% of the  profits  generated  by the Funds;  (ii) Mr.

less than 2% of the profits generated by the Funds; (iii) Mr. Schechter's profit
interests in the Funds  entitle him to less than 1% of the profits  generated by
the Funds;  and (iv) Dr. Denner's profit  interests and capital  accounts in the
Funds entitle him to less than 2% of the profits generated by the Funds.

     Each of Icahn Partners, Icahn Master, Icahn Master II, Icahn Master III and
High River is principally engaged in the business of investing in securities.

     Annex A  attached  hereto  sets  forth,  as to the  Nominees  and the other
Participants,  all transactions in securities of Biogen effected during the past
two years and their beneficial ownership of securities of Biogen.

     With respect to each  Participant  (including the Nominees),  except as set
forth herein or in any of the Annexes attached  hereto,  (i) such Participant is
not,  nor was within  the past year,  a party to any  contract,  arrangement  or
understanding  with  any  person  with  respect  to any  securities  of  Biogen,
including, but not limited to, joint ventures, loan or option arrangements, puts
or calls, guarantees against loss or guarantees of profit, division of losses or
profits,  or the  giving  or  withholding  of  proxies;  and (ii)  neither  such
Participant  nor any of such  Participant's  associates  have any arrangement or
understanding  with any person  with  respect to (A) any  future  employment  by
Biogen or its affiliates or (B) any future  transactions  to which Biogen or any
of its affiliates will or may be a party.


ELECTION OF DIRECTORS

     On  January  24,  2008 the Icahn  Parties  delivered  a letter  to  Biogen,
notifying  Biogen that the Icahn Parties  nominate and will seek to elect at the
Annual  Meeting - Dr.  Alexander  J.  Denner,  Dr.  Anne B. Young and  Professor
Richard  C.  Mulligan  as  members  of the board of  directors  of  Biogen.  The
Nominees,  if elected,  would serve a three-year  term and hold office until the
2011 annual meeting of Stockholders  and until a successor has been duly elected
and qualified.  Background  information  about each of the Nominees is set forth
below.

     According to a press release  issued by Biogen on April 17, 2008, the Board
of Directors of Biogen (the  "Board")  intend to nominate  four  candidates  for
election as directors at the Annual Meeting.  This proxy statement is soliciting
proxies to elect not only Dr. Denner, Dr. Young and Professor Mulligan, but also
all of the Biogen nominees other than Mr. Cecil B. Pickett,  Ms. Lynn Schenk and
Mr.  Stelios  Papadopoulos.  This  gives  stockholders  who wish to vote for Dr.
Denner, Dr. Young and Professor Mulligan and such other person the ability to do
so. Under  applicable proxy rules we are required either to solicit proxies only
for Dr. Denner, Dr. Young and Professor Mulligan, which could result in limiting
the ability of  Stockholders  to fully exercise their voting rights with respect
to Biogen's  nominees,  or to solicit for Dr.  Denner,  Dr. Young and  Professor
Mulligan  and  for  fewer  than  all  of  Biogen's  nominees,  which  enables  a
Stockholder who desires to vote for Dr. Denner, Dr. Young and Professor Mulligan
to also vote for those of Biogen's nominees for whom we are soliciting  proxies.
Mr.  Icahn  notes  that,  subject  to the  Stockholders  approval  of the  Bylaw
Amendments,  if Dr. Denner, Dr. Young and Professor Mulligan are elected, and if
a majority of the Board members thereafter determines that it would be desirable
that Mr. Cecil B. Pickett, Ms. Lynn Schenk and Mr. Stelios Papadopoulos serve as
Board members,  the Board could permit that result by increasing the size of the
Board  and  adding  Mr.  Cecil B.  Pickett,  Ms.  Lynn  Schenk  and Mr.  Stelios
Papadopoulos as additional members.

     Dr. Anne B. Young and  Professor  Richard C.  Mulligan are each party to an
agreement  substantially  in the form  attached  hereto as Annex B,  pursuant to
which the Icahn Parties have agreed to pay certain fees to each such Nominee and
to indemnify  each such Nominee with respect to certain  costs  incurred by each
such Nominee in connection with the proxy contest relating to the Annual Meeting
(the  "Nominee  Agreement").  Except  as  disclosed  in  this  Proxy  Statement,
including the Annexes  attached hereto and as provided in the Nominee  Agreement
(which,  among other  things,  provides  for a payment to each of Dr.  Young and
Professor  Mulligan of $25,000),  none of the Nominees  receive any compensation
from any of the  Participants or any of their affiliates in connection with this
proxy  solicitation.  Dr. Young and  Professor  Mulligan have an interest in the
election of directors at the Annual  Meeting  pursuant to the Nominee  Agreement
relating  to such  Nominee.  Dr.  Denner  has an  interest  in the  election  of
directors  at the Annual  Meeting  indirectly  through his capital  accounts and
other investments in the Funds.

     The Nominees would be considered  independent under Nasdaq Rule 4350(c) and
Rule  4200(a)(15)  and the  independence  standards  applicable  to Biogen under
paragraph (a)(1) of Item 407 of Regulation S-K under the Securities Exchange Act
of 1934, as amended.

     Other than as  disclosed  in this Proxy  Statement,  including  the Annexes
attached hereto, (i) the Nominees are not, nor were they within the past year, a
party to any contract, arrangement or understanding with any person with respect
to any securities of Biogen, including, but not limited to, joint ventures, loan
or option arrangements,  puts or calls, guarantees against loss or guarantees of
profit,  division of losses or profits, or the giving or withholding of proxies;
and (ii) none of the Nominees nor any of their  respective  associates  have any
arrangement  or  understanding  with any person  with  respect to (A) any future
employment by Biogen or its affiliates or (B) any future  transactions  to which
Biogen or any of its affiliates will or may be a party.

specializing  in imaging  platforms for medical and surgical  applications.  Dr.
Denner received his S.B. degree from the  Massachusetts  Institute of Technology
and his M.S., M.Phil. and Ph.D. degrees from Yale University.

DR. ANNE B. YOUNG

     Dr. Young,  60,  Julieanne Dorn  Professor of Neurology at Harvard  Medical
School and the Chief,  Neurology Service at Massachusetts General Hospital, is a
researcher and clinician  whose work at the bench and bedside have  concentrated
on neurotransmitter systems in the basal ganglia and their role in Huntington's,
Alzheimer's and  Parkinson's  diseases.  Dr. Young holds  membership in both the
Institute of Medicine and the American  Academy of Arts and Sciences.  Dr. Young
was inducted as a Fellow in the Royal  Academy of  Physicians in London in 2005.
Dr. Young is a Phi Beta Kappa,  summa cum laude  graduate of Vassar  College who
completed her medical  studies at Johns Hopkins in 1973. She received a Ph.D. in
Pharmacology from Johns Hopkins in 1974, and then completed  residency  training
in neurology at the University of California,  San Francisco.  After  residency,
she joined  the  neurology  faculty  at the  University  of  Michigan  where she
advanced to Professor in 1985. In 1991,  she was recruited to the  Massachusetts
General Hospital as Chief of the Neurology  Service and Julieanne Dorn Professor
of Neurology at Harvard Medical School.

     Dr. Young  provided  some of the first  evidence  that  glutamic  acid is a
neurotransmitter. Subsequently, she and her colleagues identified glutamate as a
transmitter of  corticostriatal  and corticospinal  tracts. Her laboratory first
described    techniques   to   measure    subtypes   of   glutamate    receptors
autoradiographically   and  went  on  to  demonstrate  receptor  alterations  in
Huntington's and Alzheimer's disease. Dr. Young's current research work includes
elucidating  cellular and systems mechanisms  underlying the  pathophysiology of
neurodegenerative diseases such as Huntington's disease, Alzheimer's disease and
Parkinson's  disease. In an effort to help develop therapeutic targets for human
disorders of movement, she is conducting studies on the vulnerability of neurons
to  excitotoxic  injury and the selective  expression of glutamate  receptors in
these neurons.  Recently,  she has discovered that transgenic animals expressing
exon 1 of the huntingtin protein  (Huntington's  disease is caused by a mutation
of the gene encoding this protein) have markedly altered receptors that may play
a central role in the neuronal degeneration of Huntington's disease. Her studies
suggest that mutant huntingtin may alter receptor expression selectively when it
accumulates in the nucleus.  Altered  receptor  expression  occurs early and may
contribute to selective cell death.

     Dr. Young serves on the editorial board of numerous biomedical journals and
she has been the  recipient  of many  awards and  honors for her work.  She is a
member of the Scientific Advisory Boards of several voluntary organizations. She
is the past President of the American  Neurological  Association and the Society
for Neuroscience.

PROFESSOR RICHARD C. MULLIGAN

     Professor  Mulligan,  53, is the  Mallinckrodt  Professor  of  Genetics  at
Harvard  Medical  School,  and Director of the Harvard Gene Therapy  Initiative.
Professor Mulligan received his B.S. degree from the Massachusetts  Institute of
Technology,  and his Ph.D.  from the  Department  of  Biochemistry  at  Stanford
University  School of Medicine.  After  receiving  postdoctoral  training at the
Center for Cancer Research at MIT, Professor Mulligan joined the MIT faculty and
subsequently  was  appointed  Professor of  Molecular  Biology and Member of the
Whitehead Institute for Biomedical Research before moving to Children's Hospital
and Harvard in 1996.  His honors  include the MacArthur  Foundation  Prize,  the
Rhodes  Memorial  Award of the American  Association  for Cancer  Research,  the
ASMB-Amgen  Award,  and the  Nagai  Foundation  International  Prize.  Professor
Mulligan has been associated with a number of biotechnology companies, including
Somatix Therapy  Corporation  (as founder and member of the Scientific  Advisory
Board and Board of Directors,  and Chief Scientific  Officer),  Cell Genesys (as
member of the  Scientific  Advisory  Board) and ImClone,  where he served on the
Scientific  Advisory  Board and has been a Director and member of the  Executive
Committee since September 2006. He has also served on the National Institutes of
Health's  Recombinant  DNA  Advisory  Committee  and on the  U.S.  Food and Drug
Administration Biological Response Modifiers Advisory Committee.

     WE STRONGLY  URGE YOU TO VOTE FOR THE ELECTION OF DR.  ALEXANDER J. DENNER,
DR. ANNE B. YOUNG AND PROFESSOR RICHARD C. MULLIGAN BY MARKING,  SIGNING, DATING
AND RETURNING THE ENCLOSED GOLD PROXY CARD IN THE POSTAGE PAID ENVELOPE PROVIDED
TO YOU WITH THIS  PROXY  STATEMENT  OR BY USING THE GOLD  PROXY  CARD TO VOTE BY
TELEPHONE OR INTERNET.  IF YOU HAVE SIGNED THE GOLD PROXY CARD AND NO MARKING IS
MADE,  YOU WILL BE  DEEMED  TO HAVE  GIVEN A  DIRECTION  TO VOTE ALL THE  SHARES
REPRESENTED BY THE GOLD PROXY CARD FOR THE ELECTION OF DR.  ALEXANDER J. DENNER,
DR. ANNE B. YOUNG AND PROFESSOR RICHARD C. MULLIGAN.


BYLAW AMENDMENTS

     Biogen's  ByLaws provide for a three-class  classified  board,  the size of
which  may be  expanded  by a  vote  of the  Board.  In  order  to  provide  the
Stockholders  with the  ability to elect a  majority  of  Stockholder  nominated
directors following the 2009 annual meeting, the Participants will seek to amend
the  ByLaws to fix the  number of  directors  at  twelve.  For  example,  if the
Stockholders  elect Dr.  Alexander  J. Denner,  Dr. Anne B. Young and  Professor
Richard C.  Mulligan to the Board at the 2008  Annual  Meeting,  and in 2009,  a
Stockholder nominates, and the Stockholders elect, four director nominees at the
2009 annual meeting,  then the Board would include seven  Stockholder  nominated
directors.  If the Bylaw  Amendments are adopted by the Stockholders at the 2008
Annual  Meeting  and the  Board is  fixed  at 12  directors,  then  those  seven
Stockholder  nominated  directors elected over the course of two annual meetings
would  constitute a majority of the Board.  However,  because the current Bylaws
allow the Board to expand the size of the Board, if the Bylaw Amendments are not
adopted at the 2008 Annual  Meeting and the Board  decides to expand the size of
the Board (despite the fact that such a decision to expand the size of the Board
could  constitute a breach of fiduciary duty under  applicable  law), then those
seven Stockholder  nominated directors would merely constitute a minority of the
Board. As such, the Participants will seek to amend the Bylaws:

     o    to replace the first  sentence  of Section  3.1 of the  Bylaws,  which
          reads:

               "The number of directors  that shall  constitute the entire Board
               initially  shall be  twelve  (12);  provided,  however,  that the
               number of directors that shall  constitute the entire Board shall
               be fixed from time to time by resolution adopted by a majority of
               the entire Board",

               in its entirety with the following sentence:

               "The number of directors  that shall  constitute the entire Board
               shall be twelve (12)."

     o    to delete,  in its entirety,  the first sentence of Section 3.2 of the
          Bylaws which reads:

               "The number of members of the Board may be  increased at any time
               as provided in Section 3.1 above."

     o    to  delete,   in  their   entirety,   the  words  "and  newly  created
          directorships  resulting from any increase in the authorized number of
          directors",  appearing  in the second  sentence  of Section 3.2 of the
          Bylaws which reads, in its entirety:

               "Sole power to fill  vacancies  and newly  created  directorships
               resulting from any increase in the authorized number of directors
               shall be vested in the Board,  and each  director so chosen shall
               hold office  until the next annual  election at which the term of
               the class to which they have been elected  expires and until such
               director's  successor is duly elected and qualified or until such
               director's  earlier  resignation,  removal from office,  death or
               incapacity."

WE  STRONGLY  URGE YOU TO VOTE FOR THE BYLAW  AMENDMENTS  BY  MARKING,  SIGNING,
DATING AND  RETURNING  THE ENCLOSED GOLD PROXY CARD IN THE POSTAGE PAID ENVELOPE
PROVIDED  TO YOU WITH THIS  PROXY  STATEMENT  OR BY USING THE GOLD PROXY CARD TO
VOTE BY  TELEPHONE  OR  INTERNET.  IF YOU HAVE SIGNED THE GOLD PROXY CARD AND NO
MARKING IS MADE,  YOU WILL BE DEEMED TO HAVE GIVEN A  DIRECTION  TO VOTE ALL THE
SHARES REPRESENTED BY THE GOLD PROXY CARD FOR EACH OF THE BYLAW AMENDMENTS.


OTHER PROPOSALS

     The  Participants  and their  affiliates  know of no other  business  to be
presented at the Annual  Meeting.  If any other  matters  should  properly  come
before the Annual Meeting, it is intended that the persons named on the enclosed
GOLD proxy card will vote that proxy on such other  matters in  accordance  with
their judgment.


VOTING PROCEDURES

     According to the Bylaws and applicable  law,  holders of shares of Biogen's
Common Stock, at the close of business on the Record Date are entitled to notice
of, and to vote at, the Annual Meeting.  Each share of Common Stock  outstanding
on the Record  Date is  entitled  to one vote on each  matter  presented  at the
Annual Meeting.

     According  to the Bylaws and  applicable  law,  directors  are elected by a
plurality of the votes cast by the holders of Biogen's Common Stock at a meeting
at which a quorum is present.  Plurality  means that the individuals who receive
the  largest  number of votes cast are  elected as  directors  up to the maximum
number of directors to be chosen at the  meeting.  Consequently,  any shares not
voted (whether by abstention, broker nonvote or otherwise) have no impact in the
election  of  directors.  A  quorum  is a  majority  of the  Shares  issued  and
outstanding  and entitled to vote,  present in person or represented by proxy at
the Annual  Meeting.  The Shares  represented  by a proxy marked  "withhold"  or
"abstain"  will be  considered  present at the Annual  Meeting  for  purposes of
determining a quorum.

     According to the Bylaws and  applicable  law,  amendments to the Bylaws are
effected  by the  affirmative  vote  of a  majority  of the  Shares  issued  and
outstanding and entitled to vote thereon.  An affirmative vote means that a vote
must be cast in favor of the Bylaw  Amendments.  Consequently,  any  shares  not
voted  (whether by  abstention,  broker  nonvoter or  otherwise)  would have the
effect of a vote AGAINST the Bylaw Amendments. As of the Record Date, there were
___________  Shares issued and outstanding.  As a result,  in order to amend the
Bylaws,  at least  _______  Shares must be  affirmatively  voted in FAVOR of the
Bylaw Amendments.

     As explained in the detailed  instructions  on your GOLD proxy card,  there
are four ways you may vote. You may:

     1.   Sign,  date and return the  enclosed  GOLD proxy card in the  enclosed
          postage-paid  envelope.  We recommend  that you vote on the GOLD proxy
          card even if you plan to attend the Annual Meeting;
     2.   Vote via the Internet by following the voting instructions on the GOLD
          proxy card or the voting instructions provided by your broker, bank or
          other holder of record.  If you submit your vote by Internet,  you may
          incur costs associated with electronic  access,  such as usage charges
          from Internet access providers and telephone companies;
     3.   Vote by  telephone by following  the voting  instructions  on the GOLD
          proxy card or the instructions  provided by your broker, bank or other
          holder of record; or
     4.   Vote in person by attending the Annual  Meeting.  Written ballots will
          be  distributed  to  Stockholders  who wish to vote in  person  at the
          Annual  Meeting.  If you hold your  Shares  through a bank,  broker or
          other custodian,  you must obtain a legal proxy from such custodian in
          order to vote in person at the meeting.

     To submit a proxy with voting  instructions  by  telephone  please call the
telephone  number  listed on the GOLD proxy card.  Proxies may also be submitted
over  the  Internet.  Please  refer  to the  GOLD  proxy  card  for the  website
information.  In each case  Stockholders  will be required to provide the unique
control number which has been printed on each  Stockholder's GOLD proxy card. In
addition to the  instructions  that appear on the GOLD proxy card,  step-by-step
instructions  will  be  provided  by a  recorded  telephone  message  for  those
Stockholders  submitting proxies by telephone,  or at the designated website for
those Stockholders submitting proxies over the Internet. Stockholders submitting
their  proxies with voting  instructions  by telephone or over the Internet will
receive  confirmation  on  the  telephone  that  their  vote  by  telephone  was
successfully  submitted,  and may provide an email address for confirmation that
their vote by Internet was successfully submitted.

     Whether or not you are able to attend the Annual Meeting,  you are urged to
complete the enclosed  GOLD proxy and return it in the enclosed  self-addressed,
prepaid envelope. All valid proxies received prior to the meeting will be voted.
If you specify a choice with respect to any item by marking the  appropriate box
on the proxy, the Shares will be voted in accordance with that specification. IF
NO  SPECIFICATION  IS MADE,  THE SHARES WILL BE VOTED (I) FOR DR.  ALEXANDER  J.
DENNER  FOR  DIRECTOR;  (II) FOR DR.  ANNE B.  YOUNG  FOR  DIRECTOR;  (III)  FOR
PROFESSOR  RICHARD C. MULLIGAN FOR DIRECTOR;  (IV) FOR THE PERSONS WHO HAVE BEEN
NOMINATED BY BIOGEN TO SERVE AS DIRECTORS,  OTHER THAN MR. CECIL B. PICKETT, MS.
LYNN SCHENK AND MR. STELIOS PAPADOPOULOS; (V) FOR THE BYLAW AMENDMENTS; AND (VI)
IN THE PROXY  HOLDERS'  DISCRETION  AS TO OTHER  MATTERS THAT MAY PROPERLY  COME
BEFORE THE ANNUAL MEETING.

PROXY PROCEDURES

     IN ORDER FOR YOUR VIEWS TO BE  REPRESENTED  AT THE ANNUAL  MEETING,  PLEASE
MARK,  SIGN,  DATE AND RETURN  THE  ENCLOSED  GOLD  PROXY  CARD IN THE  ENCLOSED
POSTAGE-PREPAID  ENVELOPE  OR USE THE GOLD  PROXY CARD TO VOTE BY  TELEPHONE  OR

     The  accompanying  GOLD proxy  card will be voted at the Annual  Meeting in
accordance with your instructions on such card.

     Only  holders of record as of the close of business on the Record Date will
be entitled to vote. If you were a Stockholder of record on the Record Date, you
will  retain  your  voting  rights at the Annual  Meeting  even if you sell such
shares after the Record  Date.  Accordingly,  it is important  that you vote the
shares held by you on the Record  Date,  or grant a proxy to vote such shares on
the GOLD proxy card, even if you sell such shares after the Record Date.

     IF YOUR SHARES ARE HELD IN THE NAME OF A BROKERAGE FIRM, BANK, BANK NOMINEE
OR OTHER  INSTITUTION ON THE RECORD DATE,  ONLY IT CAN VOTE SUCH SHARES AND ONLY
UPON RECEIPT OF YOUR  SPECIFIC  INSTRUCTIONS.  ACCORDINGLY,  PLEASE  CONTACT THE
PERSON  RESPONSIBLE FOR YOUR ACCOUNT AND INSTRUCT THAT PERSON TO EXECUTE ON YOUR
BEHALF THE GOLD PROXY CARD AS SOON AS POSSIBLE.


REVOCATION OF PROXIES

     Any  Stockholders  of  record  may  revoke  or  change  his  or  her  proxy
instructions at any time prior to the vote at the Annual Meeting by:

     o    submitting  a properly  executed,  subsequently  dated GOLD proxy card
          that will  revoke all prior  proxy  cards,  including  any White proxy
          cards which you may have submitted to Biogen;

     o    instructing  the Icahn  Parties by telephone or via the Internet as to
          how you would like your shares  voted  (instructions  are on your GOLD
          proxy card);

     o    attending  the  Annual  Meeting  and  withdrawing  his or her proxy by
          voting in person  (although  attendance at the Annual Meeting will not
          in and of itself constitute revocation of a proxy); or

     o    delivering  written  notice of revocation  either to the Icahn Parties
          c/o Georgeson Inc., 199 Water Street,  26th Floor,  New York, New York
          10038, or the Corporate Secretary of Biogen.

     Although a  revocation  is  effective  if  delivered  to Biogen,  the Icahn
Parties  request that either the original or a copy of any  revocation be mailed
to the Icahn Parties c/o Georgeson Inc., 199 Water Street, 26th Floor, New York,
New York 10038, so that the Icahn Parties will be aware of all revocations.

     IF YOU PREVIOUSLY SIGNED AND RETURNED A WHITE PROXY CARD TO BIOGEN, WE URGE
YOU TO REVOKE IT BY (1) MARKING,  SIGNING,  DATING AND  RETURNING THE GOLD PROXY
CARD,  (2)  INSTRUCTING  US BY TELEPHONE OR VIA THE INTERNET AS TO HOW YOU WOULD
LIKE YOUR SHARES VOTED WITH RESPECT TO THE GOLD PROXY CARD,  (3)  ATTENDING  THE
ANNUAL  MEETING  AND  VOTING  IN PERSON OR (4)  DELIVERING  A WRITTEN  NOTICE OF
REVOCATION TO THE ICAHN PARTIES OR TO THE CORPORATE SECRETARY OF THE COMPANY.


COST AND METHOD OF SOLICITATION

     Solicitation of proxies shall be made by Messrs.  Icahn,  Denner,  Meister,
Intrieri and Schechter.

     The Icahn Parties have retained Georgeson Inc. ("Georgeson") to conduct the
solicitation,  for which  Georgeson is to receive a fee not to exceed  $350,000,
plus reimbursement for its reasonable  out-of-pocket expenses. The Icahn Parties
have agreed to indemnify  Georgeson  against  certain  liabilities and expenses,
including  certain  liabilities  under the federal  securities laws.  Insofar as
indemnification for liabilities arising under the federal securities laws may be
permitted  to  Georgeson  pursuant  to the  foregoing  provisions,  we have been
informed,  that in the opinion of the Securities and Exchange  Commission,  such
indemnification is against public policy and is therefore unenforceable. Proxies
may be solicited by mail, courier services, Internet, advertising,  telephone or
telecopier  or  in  person.   It  is  anticipated  that  Georgeson  will  employ
approximately  60 persons to solicit  proxies from Biogen  Stockholders  for the
Annual Meeting. The total expenditures in furtherance of, or in connection with,
the solicitation of proxies is  approximately  $___ to date, and is estimated to
be $____ in total.

     The Icahn Parties intend to seek  reimbursement  for the costs and expenses
associated with the proxy solicitation in the event that any of the Nominees are
elected to the Board of  Directors  of  Biogen,  but do not intend to submit the
issue of reimbursement to a vote of security holders.

ADDITIONAL INFORMATION

     Certain  information  regarding  the  securities of Biogen held by Biogen's
directors,  management  and 5%  Stockholders  is  expected  to be  contained  in
Biogen's Proxy Statement.  Information concerning the date by which proposals of
security  holders  intended  to be  presented  at the  next  annual  meeting  of
Stockholders  of Biogen  must be received  by Biogen for  inclusion  in Biogen's
Proxy  Statement  and form of proxy  for that  meeting  is also  expected  to be
contained  in  Biogen's  Proxy  Statement.  This  information  is expected to be
contained in Biogen's public filings.  The Participants  take no  responsibility
for the  accuracy or  completeness  of such  information  contained  in Biogen's
public filings.

[NAME OF NOMINEE]


Dear  ___________:


     This will confirm our understanding as follows:

     You agree that you are willing, should we so elect, to become a member of a
slate of nominees  (the  "Slate") to stand for  election as  directors of Biogen
Idec Inc..  ("Biogen")  in connection  with a proxy  contest with  management of
Biogen in respect of the  election  of  directors  of Biogen at the 2008  Annual
Meeting of Stockholders of Biogen (the "Annual Meeting"), expected to be held in
the Spring of 2008, or a special  meeting of stockholders of Biogen called for a
similar purpose (the "Proxy Contest").

     Icahn  Partners LP, Icahn Partners  Master Fund LP, Icahn  Partners  Master
Fund II LP, Icahn Partners Master Fund III LP and High River Limited Partnership
(collectively, "Icahn"), agree to pay the costs of the Proxy Contest.

     In addition, upon our filing of a preliminary proxy statement with the SEC,
which  indicates  that Icahn  intends to nominate you for election at the Annual
Meeting, you will be paid $25,000 by Icahn.

     You  understand  that it may be difficult,  if not  impossible,  to replace
nominees  who,  such as  yourself,  have  agreed to serve on the Slate and later
change their minds and determine not to seek election. Accordingly, the Slate is
relying upon your agreement to seek election. In that connection,  you are being
supplied with a questionnaire  in which you will provide Icahn with  information
necessary for Icahn to make appropriate disclosure both to Biogen and for use in
creating the proxy material to be sent to stockholders of Biogen and to be filed
with the Securities and Exchange  Commission.  You have agreed that (i) you will
immediately complete and sign the questionnaire and return it to Andrew Langham,
Counsel, Icahn Enterprises LP, 767 Fifth Avenue, Suite 4700, New York, NY 10153,
Tel: (212) 702-4382, Fax: (212) 688-1158,  Email:  alangham@sfire.com,  and (ii)
your  responses to the questions  contained  therein will be true and correct in
all  respects.  In  addition,  you have  agreed  that,  concurrently  with  your
execution of this letter, you will execute the attached  instrument  directed to
Biogen  informing  Biogen  that you  consent  to being  nominated  by Icahn  for
election  as a  director  of Biogen  and,  if  elected,  consent to serving as a
director of Biogen.  Upon being notified that we have chosen you, we may forward
that consent and your completed questionnaire (or summaries thereof) to Biogen.

     Icahn hereby agrees that, so long as you actually serve on the Slate, Icahn
will  defend,  indemnify  and hold you  harmless  from and  against  any and all
losses, damages, penalties,  judgments, awards, liabilities, costs, expenses and
disbursements (including, without limitation, reasonable attorneys' fees, costs,
expenses and  disbursements)  incurred by you in the event that (i) you become a
party,  or  are  threatened  to  be  made  a  party,  to  any  civil,  criminal,
administrative or arbitrative action, suit or proceeding, and any appeal thereof
relating solely to your role as a nominee for director of Biogen on the Slate (a
"Proceeding")  or (ii) you are  called to testify  or give a  deposition  in any
Proceeding  (whether or not you are a party or are threatened to be made a party
to such  Proceeding),  including,  in each case,  the  advancement to you of all
reasonable  attorneys' costs and expenses incurred by you in connection with any
Proceeding.  Your right of  indemnification  hereunder shall continue (i) in the
event that Icahn  determines  to withdraw the Slate or remove you from the Slate
and (ii) after the  election  has taken  place but only for events  which  occur
prior to such  election  and  subsequent  to the date  hereof.  Anything  to the
contrary herein  notwithstanding,  Icahn is not  indemnifying you for any action
taken  by you or on your  behalf  which  occurs  prior  to the  date  hereof  or
subsequent  to the Annual  Meeting or such  earlier  time as you are no longer a
nominee of the Slate for  election to  Biogen's  Board of  Directors  or for any
actions taken by you as a director of Biogen, if you are elected. Nothing herein
shall be construed to provide you an  indemnity:  (i) in the event you are found
to have  engaged in a  violation  of any  provision  of state or federal  law in
connection  with the Proxy Contest unless you  demonstrate  that your action was
taken in good  faith and in a manner  you  reasonably  believed  to be in or not
opposed to the best  interests of electing the Slate;  or (ii) if you acted in a
manner which  constitutes gross negligence or willful  misconduct.  In the event
that you shall make any claim for indemnification  hereunder, you shall promptly
notify Icahn in the event of any third-party claims actually made against you or
known by you to be  threatened.  In  addition,  with  respect to any such claim,
Icahn shall be entitled to control your  defense  with counsel  chosen by Icahn.
Icahn  shall not be  responsible  for any  settlement  of any claim  against you
covered by this indemnity without its prior written consent.  However, Icahn may
not enter into any settlement of any such claim without your consent unless such
settlement  includes a release of you from any and all  liability  in respect of
such claim.

     Each of us recognizes  that should you be elected to the Board of Directors
of Biogen all of your activities and decisions as a director will be governed by
applicable law and subject to your fiduciary duty to the  stockholders of Biogen
and, as a result,  that there is, and can be, no agreement between you and Icahn
which governs the decisions which you will make as a director of Biogen.





     Should the foregoing agree with your  understanding,  please so indicate in
the space provided below,  whereupon this letter will become a binding agreement
between us. Very truly yours,

                         ICAHN PARTNERS LP
