     On June 4, 2008, Carl C. Icahn  distributed a memorandum  concerning Biogen
Idec Inc. to a number of shareholders  of Biogen Idec Inc. and other  interested
parties.  The  memorandum  is attached  hereto as Exhibit I and is  incorporated
herein by reference.





                                                                       EXHIBIT I
                                                                       ---------

              BIOGEN'S SALES PROCESS: WHEN WILL WE KNOW THE TRUTH?

         BIOGEN'S OWN DOCUMENTS SHOW A NUMBER OF STATEMENTS THEY MADE IN
                CONNECTION WITH THIS PROXY STATEMENT ARE UNTRUE.

     In  connection  with our  lawsuit  against  Biogen  Idec Inc. to compel the
Company to provide us with certain  books and records  relating to the Company's
efforts to sell itself in the fall 2007, on May 29, 2008, in compliance  with an
order  of  the  Delaware  Court  of  Chancery,  the  Company  provided  us  with
approximately 215 pages of documents concerning the failed sales process.

     On May 30, 2008, Biogen made all of those documents available to the public
through an SEC filing. In that filing, the Company asserted (among other things)
that:  "[t]hese  documents  are  consistent  with  Biogen  Idec's  prior  public
statements  about the [sale] Process and demonstrate that the [sale] Process was
comprehensive  and fair." We disagree.  The  documents are not  consistent  with
their public statements.

     The Company did not inform its  stockholders  that it had been compelled to
produce  the  documents  by the  Delaware  Court of  Chancery as a result of our
lawsuit.

     Importantly, it is clear from the documents they produced that at least one
bidder asked to talk to Elan before they  submitted a "firm and binding"  offer.
The  documents  do not indicate  whether the bidder was  permitted to speak with
Elan, but do indicate that the bidder walked away from the process.

     As we indicate below,  these documents show that a number of the statements
made by Biogen during this proxy contest are untrue.

     The  following  memorandum  briefly sets forth our initial  findings of the
many  inconsistencies  between the Company's public statements and the 215 pages
of documents recently provided to us.

--------------------------------------------------------------------------------
o    POINT ONE: During Biogen's  February 6, 2008  fourth-quarter  2007 earnings
     call, Mullen stated:

          "Our board,  in consultation  with management and advisors,  developed
          and  executed a sale  process  that was  professional,  objective  and
          thorough and was designed to elicit the highest possible value for the
          Company's shareholders."

     In addition, in responding to the Icahn entities' books and records demand,
     the Company stated:

          "[T]he  Board  authorized,  supervised  and was fully  informed of the
          design and conduct of the Strategic Process."

o    The  documents  that the Icahn  parties  compelled  the  Company to produce
     through  an  action  in the  Delaware  Court of  Chancery  (the  "Compelled
     Production")  raise serious  questions  about the veracity of the Company's
     above representations. For example:

     o    The minutes of the October  12,  2007  meeting of the Biogen  Board of
          Directors (the "Board")  produced by the Company contain no mention of
          the Board  being  advised  of the  design of the sale  process  and no
          mention of the Board approving any specific sale-process procedures.

     o    The Compelled Production does not contain a single document pre-dating
          October 12,  2007.(1)  This  strongly  suggests  that the Board had no
          involvement in developing or designing the sale process.

     o    The first  reference in any Board  minutes to potential  bidders being
          precluded  from  talking  to Elan  appears  in the  December  9,  2007
          minutes. At that meeting (which was held two days after binding offers
          were due from bidders),  Jim Mullen,  chief  executive  officer of the
          Company,  informed  the Board that a bidder  (whose  identity has been
          redacted by the Company)  "had been advised that they would be invited
          to speak with Elan after the  submission  of their  proposal  and that
          they could revise their proposal after speaking with Elan."(2)

_________________________
(1)  The Order of  Delaware  Court of Chancery  required  the Company to produce
     "all presentations,  memoranda, reports or other such material that address
     how [the sale process] was to be designed or conducted,  or how the process
     was in fact designed," which documents were provided to the Board or passed
     between any corporate officer, senior manager or advisor of the Company.
(2)  Mullen's  statement to the Board here  appears to conflict  with a November
     20, 2007 bid process letter sent by Merrill Lynch and Goldman Sachs, on the
     Company's  behalf,  to a potential bidder (whose identity was also redacted
     by the Company)  explaining how  "discussions"  with Elan would take place.
     See Point Two.



     o    After an inquiry by the Icahn  entities about the propriety of certain
          redactions in the Compelled  Production,  the Company  removed some of
          the  redactions  from the December 9, 2007 minutes.  These  unredacted
          minutes reveal that, at the December 9, 2007 Board meeting,  the Board
          requested  that "during such  meeting,  the Company's  management  and
          advisors  review  with the Board the entire  sale  process in thorough
          detail."  It  appears  that the  "such  meeting"  at which  the  Board
          requested  the review to take place was the  December  12,  2007 Board
          meeting (which is when the review did in fact take place).

     o    In addition,  the unredacted  December 9, 2007 Board minutes  identify
          "Neptune" as the previously  unidentified bidder who had not submitted
          a final bid.

     o    It appears  that the Board  received  its first  (and  only)  detailed
          explanation  of the  "design" of the sale  process at the December 12,
          2007 board meeting.  Thus, the Compelled  Documents  strongly  suggest
          that the Board was not made  aware of the  design  and  conduct of the
          sale process until it had concluded on December 12, 2007.

o    POINT  TWO:  At the  January  7, 2008  break-out  session  of the  JPMorgan
     Healthcare Conference, Mullen stated:

          "And at the end we asked  parties  to  submit a  binding  offer  and a
          marked up contract  contingent  only on the  resolution  of change and
          [sic]  control  agreements.  And then the  acquirer  or if there  were
          several very close companies would have had direct  negotiations  with
          Genentech and Elan before  executing a definitive  agreement.  So this
          last part I think sounds a lot different from what I've heard and have
          seen written out there."

     o    Among the Compelled  Production is a redacted November 20, 2007 letter
          that  invited an  unidentified  bidder  "to submit a firm and  binding
          proposal . . . for the  acquisition of Biogen Idec . . . in conformity
          with the guidelines set forth below" by "Friday, December 7, 2007 (the
          `Submission Time')."

          o    The guidelines in the letter require the proposal to (i) "include
               the  specific  price  per share  (in U.S.  Dollars)  that you are
               prepared  to pay  for all of the  outstanding  shares  of  common
               stock" and "all  outstanding  options or rights to acquire common
               stock",  (ii) "indicate the best and final  financial terms under
               which you are willing to enter into the Agreement,"  (iii) "state
               that you will execute the Agreement in the form attached  hereto"
               or include a mark-up of the Agreement  that you would sign,  (iv)
               include  "details of any required sources of financing" and "firm
               commitment letters from your financing sources,  if any," and (v)
               not be subject to "the completion of additional  business,  legal
               or other due diligence" or "financing contingencies."

          o    The letter goes on to state:

          "After the  Submission  Time,  Biogen  Idec will  select a  prevailing
          prospective  purchaser.  The selected prevailing prospective purchaser
          will be given the exclusive  opportunity to engage in discussions with
          representatives  of Elan Pharma  International  Limited  regarding the
          Tysabri collaboration.  Any such discussions would take place prior to
          entering  into the  Agreement  and would be limited to a defined  time
          period"  (emphasis  added).  In fact, the way that letter is written a
          bidder could  conclude that no matter what they  discussed  with Elan,
          the bidder would have to thereafter execute the merger agreement.

          o    Comparing  Mullen's  above  comments to the November 20, 2007 bid
               process letter reveals the following inconsistencies:

               o    The  November  20,  2007  letter  calls  into  question  the
                    accuracy of Mr. Mullen's  representation  that "the acquirer
                    or if there were several very close companies would have had
                    direct negotiations with Elan and Genentech before executing
                    a definitive  agreement."  The November 20, 2007 bid process
                    letter  gave the  prevailing  bidder the right to "engage in
                    discussions"  with Elan about the "Tysabri  collaborations,"
                    but the letter  says  nothing  about  bidders  being able to
                    further negotiate price or other terms with Biogen following
                    those discussions.

               o    The bid process letter clearly states that "Biogen Idec will
                    select a prevailing  prospective  purchaser"  who would then
                    have the  opportunity to engage in  "exclusive"  discussions
                    with Elan.  Thus,  it appears  that only one bidder would be
                    permitted  to have  exclusive  discussions  with  Elan,  not
                    "several very close companies" as Mullen asserted.

               o    The November 20, 2007 letter also says nothing about bidders
                    being permitted to talk to Genentech.

o    POINT  THREE:  At the  January 7, 2008  break-out  session of the  JPMorgan
     Healthcare Conference, Mullen stated:

          "And from our  perspective  we don't believe that that CDA created any
          impediments to the sale process, and that is something we specifically
          reviewed with the Board of Directors to ensure that we were  satisfied
          with that."

     At the same session, Mullen further stated:

          "I don't  believe the CDA in any way gotten [sic] in the way of people
          entering the process or continuing the process."

     Also, in the Company's  response to the Icahn  entities'  books and records
     demand, the Company asserted that:

          "[The CDAs] requirements did not dissuade potential bidders from fully
          participating in the Strategic Process at any stage . . ."

     o    The  following  documents  in the  Compelled  Production  suggest that
          managements' above statements are not accurate:

          o    The  December  12, 2007 Board  minutes also reflect that at least
               one   potential    bidder   "had   requested   a   meeting   with
               representatives   of  Elan  Corporation  prior  to  submitting  a
               proposal." A reader could conclude from the same minutes that the
               Company  did not allow  such a meeting  to occur  because  of the
               sale-process  procedures.  Finally, the December 12, 2007 minutes
               reflect that the bidder  "declined to submit a final  proposal by
               the due date" established by the Company.

          o    A reader  could  conclude  from the December 9 and 12, 2007 Board
               minutes (and other  public  statements  by the Company)  that the
               restriction  against bidders talking to Elan and Genentech did in
               fact  dissuade  potential  bidders from  "entering the process or
               continuing the process."

          o    Finally,   the  above-quoted  minutes  also  call  into  question
               Mullen's  conflicting public  explanations for the failure of the
               sale process.  At one point,  Mullen claimed that the failure was
               caused by "market  conditions"  and, at  another,  he said it was
               because  "the  perceived  risk profile of TYSABRI at this time is
               simply too great." As stated above,  a reader of the December 12,
               2007 minutes could  conclude  that,  with regards to at least one
               bidder,  the sale process failed because the Company refused that
               bidder's request to talk to Elan.

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

In conclusion, Biogen's books and records show that:

     o    the Board had very little input in designing and supervising the sales
          process,

     o    it appears  at least one  potential  bidder was denied its  request to
          talk to Elan before submitting a binding offer,  which may have caused
          that bidder to walk away from the process, and

     o    a  number  of  Biogen's  assertions  regarding  the  process  are  not
          consistent with their own documents.
