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

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 2009 Annual Meeting (the "Annual
Meeting") of  Stockholders of Biogen which is scheduled to be held at 9:00 A.M.,
local  time,  on [ ] at  the [ ],  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 [ ].

          1. 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.  Richard  C.  Mulligan,  Dr.  Thomas F.  Deuel  and Dr.  David
     Sidransky (each a "Nominee", and collectively, the "Nominees") who has each
     consented to being named in this Proxy Statement and, if elected,  to serve
     as a director.

          2. The  Participants  will seek to amend Biogen's Amended and Restated
     ByLaws (the  "Bylaws")  to fix the number of  directors  at thirteen  (13).
     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 2010 annual meeting,  the Participants will seek to
     amend the ByLaws to fix the  number of  directors  at  thirteen  (13).  For
     example,  if the Stockholders elect Dr. Alexander J. Denner, Dr. Richard C.
     Mulligan,  Dr. Thomas F. Deuel and Dr. David  Sidransky to the Board at the
     2009  Annual  Meeting,  and in  2010,  a  Stockholder  nominates,  and  the
     Stockholders  elect,  three director  nominees at the 2010 annual  meeting,
     then the Board would include seven Stockholder nominated directors.  If the
     Icahn Bylaw  Amendments (as defined below) are adopted by the  Stockholders
     at the 2009  Annual  Meeting and the Board is fixed at 13  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
     Icahn Bylaw  Amendments  are not adopted at the 2009 Annual Meeting and the
     Board decides to expand the size of the Board (despite the possibility 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  could  constitute  merely a minority of the Board. As
     such, the  Participants  will seek to amend the Bylaws  (collectively,  the
     "Icahn 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 thirteen (13)."

          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 currently 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."

          3.  The  Participants  will  seek  to  propose  a  resolution  to  the
     Stockholders of Biogen whereby the  Stockholders  request that the Board of
     Biogen promptly initiate and complete the necessary and appropriate process
     so that the  Stockholders  of Biogen can choose whether to change  Biogen's
     jurisdiction of  incorporation  from Delaware to North Dakota and to become
     subject  to  the  North  Dakota  Act  (the  "North  Dakota  Reincorporation
     Resolution").

     DR. ALEXANDER J. DENNER,  DR. RICHARD C. MULLIGAN,  DR. THOMAS F. DEUEL AND
DR. DAVID SIDRANSKY URGE  STOCKHOLDERS TO VOTE FOR EACH OF THEM AS DIRECTORS AND
TO VOTE FOR EACH OF THE ICAHN BYLAW  AMENDMENTS AND TO VOTE FOR THE NORTH DAKOTA
REINCORPORATION RESOLUTION.

     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 (i) in the case of Dr.  Mulligan,  Dr.
Deuel and Dr. Sidransky, pursuant to an agreement in which certain affiliates of
Carl C.  Icahn  have  agreed  to pay each of Dr.  Mulligan,  Dr.  Deuel  and Dr.
Sidransky  $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"),  and (ii) in the case
of Mr. Meckler and Dr. Ende, pursuant to their respective Consulting Agreements,
as described herein.

     DR. ALEXANDER J. DENNER,  DR. RICHARD C. MULLIGAN,  DR. THOMAS F. DEUEL AND
DR.  DAVID  SIDRANSKY  ARE  COMMITTED  TO  ACTING  IN THE BEST  INTEREST  OF ALL
STOCKHOLDERS  OF  BIOGEN.  WE URGE YOU TO VOTE YOUR GOLD  PROXY CARD (I) FOR DR.
ALEXANDER J. DENNER, DR. RICHARD C. MULLIGAN,  DR. THOMAS F. DEUEL AND DR. DAVID
SIDRANKSY,  (II) FOR THE ICAHN BYLAW  AMENDMENTS  AND (III) FOR THE NORTH DAKOTA
REINCORPORATION RESOLUTION.

     Icahn  Partners,  Icahn Master,  Icahn Master II, Icahn Master III and High
River (collectively,  the "Icahn Parties") are entities controlled by Mr. Icahn.
Dr.  Denner and Mr. Sris.  are  employees  and/or  officers and directors of the
Icahn  Parties and various other  entities  controlled by Mr. Icahn who may also
participate  in soliciting  proxies from Biogen  Stockholders.  Dr. Ende and Mr.
Meckler are consultants  hired by the Icahn Parties.  Dr. Denner,  Mr. Sris, Dr.

Biogen. Neither Dr. Denner nor Mr. Sris will receive any special compensation in

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

another  solicitation  of  proxies  by the  Icahn  Parties,  as well as  general

the  Annual  Meeting  of Biogen and the  annual  meeting  relating  to the other
solicitation  are  each  held in May,  and  further  assuming  each  contest  is
successful,  the  consulting  agreements  referenced  to herein may  provide for
payments  to Dr.  Ende and Mr.  Meckler of up to  approximately  $325,000 in the
aggregate.

     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.


PROPOSAL 1 -- ELECTION OF DIRECTORS

     On  February  5,  2009 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. Richard C. Mulligan, Dr. Thomas F.
Deuel and Dr.  David  Sidransky  as members of the board of directors of Biogen.
The Nominees,  if elected,  would serve a three-year  term and hold office until
the 2012 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.

     Dr.  Richard C. Mulligan,  Dr. Thomas F. Deuel and Dr. David  Sidransky 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.
Mulligan, Dr. Deuel and Dr. Sidransky 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.  Mulligan,  Dr.  Deuel and Dr.
Sidransky  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 not be barred from being  considered  independent  under
the  independence  requirements  of  The  NASDAQ  Stock  Market,  Inc.  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

PROPOSAL 2 -- ICAHN 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 2010 annual meeting, the Participants will seek to amend
the ByLaws to fix the number of directors at thirteen (13). For example,  if the
Stockholders elect Dr. Alexander J. Denner, Dr. Richard C. Mulligan,  Dr. Thomas
F. Deuel and Dr. David Sidransky to the Board at the 2009 Annual Meeting, and in
2010,  a  Stockholder  nominates,  and the  Stockholders  elect  three  director
nominees  at the  2010  annual  meeting,  then the  Board  would  include  seven
Stockholder  nominated  directors.  If the Icahn Bylaw Amendments are adopted by
the  Stockholders  at the  2009  Annual  Meeting  and the  Board  is fixed at 13
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 Icahn Bylaw  Amendments  are not adopted at the 2009 Annual  Meeting and the
Board decides to expand the size of the Board (despite the possibility 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  could  constitute  merely 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 thirteen (13)."

          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 currently 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 ICAHN 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 THE ICAHN BYLAW AMENDMENTS.

PROPOSAL 3 -- NORTH DAKOTA REINCORPORATION RESOLUTION

     The proposal states:

          "RESOLVED, that the stockholders of the Corporation hereby request the
     Board of  Directors of the  Corporation  to take all action as is necessary
     and appropriate to properly initiate and complete the process to change the
     Corporation's  jurisdiction of incorporation  from Delaware to North Dakota
     and to become  subject to the North  Dakota  Publicly  Traded  Corporations
     Act."

     The   Icahn    Parties    believe   that   North   Dakota   is   the   most
stockholder-friendly   jurisdiction   in  the  United   States  and  that  being
incorporated  there  and  subject  to  the  North  Dakota  Act  would  give  the
Stockholders  considerably more protection against  management  entrenchment and
would make it easier for third parties to successfully  bid for the Corporation.
Although there can be no  assurances,  this could enable  stockholders,  in some
cases, to achieve a premium over market for their shares.

     Other   than  the  change  in   corporate   domicile,   the  North   Dakota
reincorporation  is not  intended  to  result  in any  change  in the  business,
physical location,  management, assets, liabilities or net worth of the Company,
nor is it intended  to result in any change in  location  of Company  employees,
including  the  Company's  management.  Upon  consummation  of  a  North  Dakota
reincorporation,  it is anticipated  that the daily  business  operations of the
Company will continue as they are presently conducted

Principal Reasons for the Reincorporation

     The  Icahn   Parties   believe  that  there  are  several   reasons  why  a
reincorporation  to North  Dakota  and  becoming  subject  to the  North  Dakota
Publicly  Traded  Corporations  Act is in the best  interests  of Biogen and the
Stockholders.  If the Company were governed by the North Dakota  Publicly Traded
Corporations Act:

o    The board of directors would be elected by a majority vote (as opposed to a
     mere  plurality) and directors  defeated  under the majority  voting system
     would be prohibited  from being appointed by the board of directors to fill
     a vacancy;

o    The board of directors could not be classified  (staggered),  each director
     would be elected every year and the board of directors would not be able to
     change  its size when it has reason to  believe  there will be a  contested
     election;

o    The  chairman  of the board of  directors  could not serve as an  executive
     officer;

o    Stockholders  who have held five percent (5%) or more of the  Corporation's
     outstanding shares for at least two years would have access to management's
     proxy statement to nominate directors;

o    All  stockholders  would be reimbursed  for proxy  contest  expenses in the
     election of directors, to the extent they are successful;

o    Stockholders would be statutorily entitled to an advisory vote each year on
     executive compensation (a "say on pay" proposal);

o    The ability of the board of  directors  to adopt and maintain a poison pill
     would be limited in several respects;

o    Antitakeover provisions proposed for inclusion in the Corporation's charter
     or bylaws  would  require the prior  approval of  two-thirds  of the shares
     entitled to vote;

o    Stockholders  could not be required  to provide  more than ninety (90) days
     notice in advance of a stockholder  meeting when making  nominations to the
     board  of  directors  and  there  would  be  limitations  on  the  type  of
     information that could be required in connection with such nominations;

o    Stockholders  who own 5% or more of the  Corporation's  outstanding  shares
     would have a right to propose and approve  amendments to the  Corporation's
     charter without prior board approval; and

o    The  Corporation  could not add a requirement to its charter or bylaws that
     certain actions require the approval of a super majority vote.

     The  North  Dakota   Publicly   Traded   Corporations   Act  would  provide
stockholders  more rights than are  generally  currently  available  under other
state corporation laws,  including Delaware,  where the Corporation is currently
incorporated.  Moreover,  the North  Dakota  Publicly  Traded  Corporations  Act
expressly  provides that it "must be liberally  construed to protect and enhance
the rights of shareholders in publicly traded corporations."

     In addition to providing  increased  stockholder  rights,  the North Dakota
Publicly  Traded  Corporations  Act  contains a  franchise  tax  system  that is
specifically  designed to impose  significantly  less cost on companies than the
Delaware   franchise  tax  system,   thereby   providing   additional  value  to
stcokholders.

WE STRONGLY URGE YOU TO VOTE FOR THE NORTH DAKOTA  REINCORPOATION  RESOLUTION 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 NORTH DAKOTA
REINCORPORATION RESOLUTION.


OTHER MATTERS TO BE CONSIDERED AT THE ANNUAL MEETING

     According to Biogen's Proxy  Statement,  Biogen is soliciting  proxies with
respect to two proposals  other than the election of directors,  the Icahn Bylaw
Amendments  and the North  Dakota  Reincorporation  Resolution.  Please refer to
Biogen's Proxy Statement for a detailed discussion of these proposals, including
various  arguments in favor of and against such  proposals.  These proposals are
outlined  below.  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 OF THE  SHARES
REPRESENTED BY YOUR GOLD PROXY CARD (I) FOR PROPOSAL [ ] BELOW, AND (II) AGAINST
PROPOSAL [ ] BELOW.

PROPOSAL  4  -  RATIFICATION  OF  SELECTION  OF  INDEPENDENT  REGISTERED  PUBLIC
                ACCOUNTING FIRM

     At the Annual Meeting, the Stockholders will be asked to vote to ratify the
selection  of  PricewaterhouseCoopers  LLP as  Biogen's  independent  registered
public accounting firm. Biogen's Board of Directors  recommended a vote for this
proposal. The Participants intend to vote, and recommend that you vote, [ ] this
proposal.

PROPOSAL 5 -- BIOGEN BYLAW AMENDMENTS

     At the Annual Meeting,  the  Stockholders  will be asked to vote to approve
amendments to Biogen's  Bylaws to change the voting standard for the election of
directors  in  uncontested  elections  from a  plurality  standard to a majority
standard.  Biogen's Board of Directors recommended a vote for this proposal (the
"Biogen Bylaw Amendments").  The Participants intend to vote, and recommend that
you vote, [ ] this proposal.

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 Biogen's  Proxy  Statement,  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 Biogen's  Proxy  Statement,  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 Biogen's  Proxy  Statement,  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 Icahn  Bylaw  Amendments.
Consequently,  any shares not voted (whether by abstention,  broker  nonvoter or
otherwise)  would have the effect of a vote AGAINST the Icahn Bylaw  Amendments.
According to the Biogen Proxy  Statement,  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  Icahn  Bylaw
Amendments.

     According  to Biogen's  Proxy  Statement,  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  Biogen  Bylaw  Amendments.
Consequently,  any shares not voted (whether by abstention,  broker  nonvoter or
otherwise) would have the effect of a vote AGAINST the Biogen Bylaw  Amendments.
According to the Biogen Proxy  Statement,  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  Biogen  Bylaw
Amendments.

     According to Biogen's Proxy  Statement,  the Bylaws and applicable law, the
affirmative  vote of a majority of Shares  present in person or  represented  by
proxy at the Annual  Meeting and entitled to vote thereon are required to ratify
the selection of the independent registered accounting firm.

     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

          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

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

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
INTERNET.

     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.

BROKER NON-VOTES

     If  you  hold  your  shares  in  street  name  and do  not  provide  voting
instructions  to your  broker,  your shares will not be voted on any proposal on
which your broker does not have discretionary authority to vote. In this case, a
"broker non-vote" occurs.  Shares  constituting broker non-votes are not counted
or deemed to be present or represented  for the purpose of  determining  whether
shareholders  have  approved a matter,  but they are  counted as present for the
purpose of determining a quorum at the Annual Meeting.

     For the Annual Meeting,  because the  solicitation of proxies  described in
this proxy  statement,  the  election of  directors  at the Annual  Meeting is a
"non-routine  matter" and brokers do not have  discretionary  authority  to vote
your shares on "non-routine  matters."  Therefore,  unless you provide  specific
voting instructions to your broker, they would not have discretionary  authority
to vote your shares for the election of directors at the Annual Meeting and your
shares  would not be voted for any of the  Nominees.  If your shares are held in
street name, your broker or nominee has enclosed a voting  instruction card with
this proxy statement. We strongly encourage you to vote your shares by following
the instructions provided on the proxy card.

     IF YOUR SHARES ARE HELD IN THE NAME OF A BROKERAGE FIRM, BANK, BANK NOMINEE

UPON RECEIPT OF YOUR  SPECIFIC  INSTRUCTIONS.  ACCORDINGLY,  PLEASE  CONTACT THE
PERSON  RESPONSIBLE FOR YOUR ACCOUNT AND INSTRUCT THAT PERSON TO EXECUTE ON YOUR

REVOCATION OF PROXIES

     Any   Stockholder  of  record  may  revoke  or  change  his  or  her  proxy
instructions  at any time prior to the vote at the Annual  Meeting in any of the
following ways, 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    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 D.F. King & Co.,  Inc., 48 Wall Street,  New York, New York 10005,
          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 D.F. King & Co.,  Inc., 48 Wall Street,  New York,  New
York 10005, 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 IN ANY OF THE FOLLOWING WAYS: BY (1) MARKING,  SIGNING,  DATING
AND  RETURNING  THE GOLD PROXY CARD,  (2) BY TELEPHONE OR VIA THE INTERNET AS TO
HOW YOU WOULD  LIKE YOUR  SHARES  VOTED  WITH  RESPECT  TO THE GOLD  PROXY  CARD
(INSTRUCTIONS  ARE ON 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 will be made by Messrs.  Icahn,  Denner, Sris, Ende
and Meckler.

     The Icahn  Parties  have  retained  D.F.  King & Co.,  Inc.  ("DF King") to
conduct the solicitation, for which DF King is to receive a fee not to exceed $[
], plus  reimbursement  for its  reasonable  out-of-pocket  expenses.  The Icahn
Parties  have  agreed to  indemnify  DF King  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 DF King 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 DF King will employ
approximately  [ ] 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 $[ ] million 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 stockholders.

[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
