                             HOPPER INVESTMENTS LLC

Dear Fellow Stockholders of ImClone Systems Incorporated:

Written  consents  are being  solicited  by Carl C. Icahn,  Alexander J. Denner,
Peter S. Liebert,  Barberry  Corp.,  High River Limited  Partnership  and Hopper
Investments  LLC,  and not by ImClone  Systems  Incorporated  ("ImClone"  or the
"Company").

We  originally  determined  to  solicit  written  consents  to  remove  the four
directors named below as well as Messrs. David M. Kies and William W. Crouse. On
October 10, 2006,  ImClone announced that Messrs.  Kies and Crouse resigned from
the Board of Directors (the  "Resignations").  Therefore,  we are now requesting
that you act by written  consent  (1) to remove the four  directors  named below
from the  Company's  twelve  member  board and (2) to fill one of the  vacancies
resulting from the removal or from the  Resignations  with the person also named
below.

We are soliciting your written consent to approve the following:

o    the removal  without cause of Vincent T. DeVita,  Jr., M.D., John A. Fazio,
     Joseph L.  Fischer  and  William  R.  Miller  from the  Company's  Board of
     Directors and any other person or persons  (other than the persons  elected
     pursuant to this proposed action by written  consent)  elected or appointed
     to the Board of the Company prior to the effective date of these  Proposals
     to fill any newly-created directorship or vacancy on the Board;

o    the appointment of Peter S. Liebert, M.D, to serve as a member of the Board
     to fill one of the newly-created  vacancies or one of the vacancies created
     by the Resignation (the "Nominee");

Our Nominee,  together with Carl C. Icahn, Andrew G. Bodnar M.D., J.D, Alexander
J. Denner Ph.D, Richard C. Mulligan, Ph.D., David Sidransky, M.D, Charles Woler,
M.D., Ph.D.,  M.B.A. (Mr. Icahn and Drs. Bodnar,  Denner,  Mulligan,  Sidransky,
Woler, collectively,  the "Remaining Directors"),  will actively work to improve
the Company's  long-term  viability  and stock price.  Neither Mr. Icahn nor Dr.
Denner have any agreements or understandings  with the other Remaining Directors
or Dr.  Liebert  as to any  particular  course  of  action  which  the Board may
undertake in the future.

In the event that the stockholders  approve the removal of the four directors we
are  proposing  to remove  but fail to  appoint  Dr.  Liebert as a member of the
Board, the Remaining Directors will constitute less than the quorum required for
Board action in accordance with the Company's  by-laws.  However,  in accordance
with  Delaware  law,  without  a  requirement  of any  stockholder  action,  the
Remaining  Directors  will  be able to  fill  one or more of the  then  existing
vacancies on the Board.  We expect that if the  Remaining  Directors  constitute
less  than  the  required  quorum,  they  will  seek to fill  one or more of the
vacancies so that the Board will be able to comply with the quorum  requirement.
Although  no  determination  was  made as any  particular  individuals  to be so
appointed,  who could be Dr. Liebert among others,  such decision if made by the
Remaining  Directors,  will  be  made  by  them  as  fiduciaries  for all of the
stockholders.

Three of the Remaining  Directors,  which include Mr. Icahn,  Dr. Denner and Dr.
Sidransky, are currently serving

                                       -1-


on the Chief Executive Officer Search Committee of the Company together with two
other  directors  we are  seeking to remove  from the Board.  Mr.  Icahn and Dr.
Denner as  members  of such  committee  currently  have a role in the  Company's
search for a new Chief Executive Officer. Mr. Icahn and Dr. Denner will continue
in such  search  for a  permanent  Chief  Executive  Officer  and we expect  the
reconstituted  Board  will also  proceed  rapidly to find such  permanent  Chief
Executive Officer.

We decided to proceed with this consent solicitation,  notwithstanding our prior
statements  in Item 4 on Schedule 13D on August 23, 2006 (in which it was stated
that "Mr.  Icahn has  agreed  to accept  management's  offer in order to avoid a
possible proxy contest which he agrees with Issuer would be disruptive to Issuer
and therefore very damaging to it") because:

o    We had assumed from statements made by Mr. David M. Kies that he would give
     up his  chairmanship  position  with the  Board of  ImClone  following  his
     reelection to the Board by the  stockholders  on September  20, 2006,  but,
     instead, Mr. Kies actively sought reelection and was reelected chair by the
     majority of the Board on September 20, 2006.

o    Mr. Icahn  indicated to ImClone his strong  belief that ImClone  should not
     enter into a long-term  agreement  with Mr. Joseph L. Fischer,  its current
     temporary  Chief  Executive   Officer,   but  instead  ImClone   apparently
     determined to enter into an agreement  with Mr. Fischer as disclosed in its
     Form 8-K filed with the  Securities  and Exchange  Commission on August 24,
     2006.

THE NOMINEE,  IF APPOINTED,  AND THE REMAINING  DIRECTORS ARE REQUIRED TO ACT IN
THE BEST INTEREST OF THE COMPANY'S STOCKHOLDERS.

WE  BELIEVE  THAT YOUR  VOICE IN THE  FUTURE OF  IMCLONE  CAN BEST BE  EXPRESSED
THROUGH YOUR CONSENT TO THE TWO PROPOSALS OUTLINED ABOVE.

The enclosed  consent  solicitation  statement  contains  important  information
concerning our solicitation and our Nominee--please read it carefully.

WE URGE YOU TO PROTECT  YOUR  INVESTMENT  IN IMCLONE NOW BY SIGNING,  DATING AND
RETURNING THE ENCLOSED WHITE CONSENT CARD TODAY.

The  results of our  consent  solicitation  will be  communicated  to you by the
issuance of a press release.  Additionally,  in accordance  with applicable law,
prompt  notice of the action taken by consent  will be provided to  stockholders
who have not executed consents.

                                      -2-




Please  consent  with  respect to all shares for which you are  entitled to give

                                       AND
                             HOPPER INVESTMENTS LLC

Carl C. Icahn, Alexander J. Denner, Peter S. Liebert, Barberry Corp., High River
Limited  Partnership  and Hopper  Investments  LLC are  furnishing  this Consent
Solicitation Statement in connection with their solicitation of written consents
from the holders of common stock,  par value $.001 per share (the "Shares"),  of
ImClone  Systems  Incorporated,   a  Delaware  corporation   ("ImClone"  or  the
"Company"),  to take the following  actions without a  stockholders'  meeting in
accordance with Delaware law:

(1) remove without cause Vincent T. DeVita,  Jr., M.D., John A. Fazio, Joseph L.
Fischer and William R. Miller from the Board of  Directors  of the Company  (the
"Board")  together  with any other  person or persons  (other  than the  persons
elected  pursuant  to this  proposed  action  by  written  consent)  elected  or
appointed  to the  Board of the  Company  prior to the  effective  date of these
Proposals  to fill any  newly  created  directorship  or  vacancy  on the  Board
("Proposal 1");

(2) elect Peter S.  Liebert,  M.D (the  "Nominee")  to fill one of the vacancies
resulting from Proposal 1 or one of the vacancies  created by the Resignation to
serve as a member of the Board of the Company ("Proposal 2");

Each  Proposal  will be  effective  without  further  action  when we deliver to
ImClone  properly  executed and dated and  unrevoked  written  consents from the
holders of a majority  of the issued and  outstanding  Shares on the record date
for this solicitation,  please see "Consent  Procedure" on page 17. According to
the Company's  press  release dated October 3, 2006,  the Board of Directors has
fixed  October  3,  2006  (the  "Record  Date"),  as the  record  date  for  the
determination  of the  Company's  stockholders  who  are  entitled  to  execute,
withhold or revoke consents relating to this solicitation.

The purpose of the consent solicitation is to remove four directors and to elect
one new  director to the Board.  Mr.  Icahn and Dr.  Denner  believe that if the
Proposals become  effective and the Board is reconstituted as a result,  the new
Board will be better suited to implement new strategies to maximize  stockholder
value. There are no assurances that any of the Remaining  Directors would remain
on the Board if the Proposals are approved.

THIS CONSENT  SOLICITATION IS BEING MADE BY CARL C. ICAHN,  ALEXANDER J. DENNER,
PETER S.  LIEBERT,  BARBERRY  CORP.  HIGH RIVER LIMITED  PARTNERSHIP  AND HOPPER
INVESTMENTS  LLC AND NOT BY OR ON  BEHALF  OF THE  COMPANY.  WE ARE  ASKING  THE
STOCKHOLDERS  OF THE  COMPANY TO ACT BY WRITTEN  CONSENT  WITH  RESPECT TO THESE
PROPOSALS ON THE ACCOMPANYING WHITE CONSENT CARD.

A consent  solicitation  such as this allows a company's  stockholders to act by
submitting written consents to proposed stockholder actions in lieu of voting in
person  or by proxy at an annual  or  special  meeting  of  stockholders.  To be
adopted by written consent, each Proposal needs to be approved by the holders of
a majority of the  outstanding  Shares on the Record Date for the  solicitation.
For a description of the Record Date see "Consent Procedure" on page 17.

                                      -5-



For the Proposals to be effective,  the Company must receive properly  completed
and duly delivered  unrevoked written consents to the Proposals from the holders
of a majority of the Shares then outstanding within 60 calendar days of the date
of the earliest dated consent delivered to the Company. See "Consent Procedure."

This Consent Solicitation Statement and the related WHITE consent card are first
being sent or given on or about October 17, 2006, to holders of Shares.

We urge you to vote in favor of the  Proposals by signing,  dating and returning
the enclosed  WHITE consent card.  The failure to sign and return a consent will
have the same effect as voting against the Proposals.

              QUESTIONS AND ANSWERS ABOUT THIS CONSENT SOLICITATION

The  following  are some of the questions  you, as a  stockholder,  may have and
answers to those  questions.  The following is not meant to be a substitute  for
the information contained in the remainder of this document, and the information
contained below is qualified by the more detailed  descriptions and explanations
contained  elsewhere in this document.  We urge you to read this entire document
carefully  prior  to  making  any  decision  on  whether  to grant  any  consent
hereunder.


Q:   Who is making the solicitation?

A:   In addition to the Nominee (who is Peter S. Liebert, M.D), the participants
     in this  consent  solicitation  (the  "Participants")  are  Carl C.  Icahn,
     Alexander J. Denner,  Barberry Corp., a Delaware corporation  ("Barberry"),
     High River  Limited  Partnership,  a Delaware  limited  partnership  ("High
     River") and Hopper  Investments LLC, a Delaware limited  liability  company
     ("Hopper") (Mr. Icahn, Dr. Denner,  Barberry and High River,  collectively,
     the  "Icahn  Parties").  Barberry,  High  River  and  Hopper  are  entities
     controlled  by Mr. Icahn.  Each of Barberry and High River are  principally
     engaged in the business of holding and investing in  securities.  Hopper is
     the  general  partner of High  River.  Hopper is  primarily  engaged in the
     business  of acting as the  general  partner of High River and  holding and
     investing in securities. Barberry is the sole member of Hopper. Barberry is
     wholly-owned by Mr. Icahn.

     Mr. Icahn and Dr. Denner are currently serving on the Board of Directors of
     ImClone.  Dr. Denner is employed by entities  controlled by Mr. Icahn. None
     of Mr. Icahn,  Dr. Denner or Dr.  Liebert will receive any payment or other
     compensation in connection with this solicitation.


Q:   What are you asking that the stockholders consent to?

A:   We are asking you to act by written  consent to approve the two  Proposals.
     Proposal 1 seeks to remove four  members of the Board named in the proposal
     and Proposal 2 seeks to elect one  individual  to fill one of the vacancies
     resulting  from  Proposal  1  or  one  of  the  vacancies  created  by  the
     resignations of Mr. Kies and Mr. Crouse.


Q:   Why are you soliciting stockholders' consent?

A:   We are soliciting your written consent because we believe the current Board
     as constituted  and the current  management  team are not pursuing the most
     effective  plan to protect  and enhance  your  investment  in  ImClone.  We
     believe much more can be done to maximize  stockholder value and that it is
     time for  immediate  change  at both the  Board and  management  level.  We
     believe the approval of our Proposals will provide the Company with a Board
     that is better suited to take decisive steps to maximize stockholder value.


Q:   Who is the Icahn Parties' Nominee?

A:   Peter S. Liebert,  M.D. The principal occupation and business experience of
     Dr.  Liebert  is set  forth  under the  section  entitled  "Proposal  No. 2
     Election of Nominee," which we urge you to read.





                                      -8-



Q:   Who can act by written consent on the Proposals?

A:   Stockholders on the record date for the solicitation are entitled to act by
     written consent on the Proposals.  According to the Company's press release
     dated October 3, 2006,  the Board of Directors has fixed October 3, 2006 as
     the record date for the determination of the Company's stockholders who are
     entitled  to  execute,   withhold  or  revoke  consents  relating  to  this
     solicitation, please see "Consent Procedure" on page 17.


Q:   When is the deadline for submitting consents?

A:   We urge you to sign,  date and return your consent card as soon as possible
     so that the four  directors  we are  seeking to remove are  removed and our
     Nominee  can be  seated on the  Board.  In order  for our  Proposals  to be
     adopted,  the Company must receive written  unrevoked  consents signed by a
     sufficient number of stockholders to adopt the Proposals within 60 calendar
     days of the date of the earliest  dated  consent  delivered to the Company.
     Because the Proposals will become effective upon our delivery to ImClone of
     valid and unrevoked consent cards totaling more than 50% of the outstanding
     Shares  as of the  record  date,  and  because  this may occur  before  the
     expiration of the 60-day period, WE URGE YOU TO ACT PROMPTLY to assure that
     your vote will count.


Q:   How many consents must be granted in favor of the Proposals to adopt them?

A:   These  Proposals  will  be  adopted  and  become  effective  when  properly
     completed,  unrevoked  consents  are signed  and dated by the  holders of a
     majority of the Shares  outstanding on the record date for the solicitation
     as set forth in "Consent Procedure" on page 19, provided that such consents
     are  delivered  to the Company  within 60 calendar  days of the date of the
     earliest  dated  consent  delivered  to the Company.  The actual  number of
     Shares  necessary  to approve  the  Proposals  will depend on the number of
     Shares outstanding on the record date, as set forth in "Consent  Procedure"
     on page 17.


Q:   What should I do to consent?

A:   Sign,  date and return the enclosed WHITE consent card today to D.F. King &
     Co.,  Inc. in the enclosed  postage-paid  envelope.  For your consent to be
     valid, your consent card must be signed and dated.


Q:   What should I do if I decide to revoke my consent?

                             ADDITIONAL INFORMATION


     Certain  information  regarding the securities of ImClone held by ImClone's
Directors,  management  and 5%  Stockholders  is contained  in  ImClone's  Proxy
Statement,  filed on Schedule 14A with the Securities and Exchange Commission on
August 31, 2006, and such information is incorporated herein by reference.

     The Board, if it is  reconstituted  as proposed in this Consent  Statement,
may not immediately  thereafter have a person who is independent and at the same
time has the financial  sophistication  that  qualifies such person to be on the
audit  committee of a  NASDAQ-listed  company  under the last sentence of NASDAQ
Rule  4350(d)(2)(A).  In such event, we expect that the reconstituted Board will
immediately  start the search for such an individual,  who, when found,  will be
appointed to the Board.

     The reconstituted Board may in the future reduce the Board to eliminate the
vacancies  resulting  from the Proposals or appoint one or more  individuals  to
fill some or all of such vacancies.  In that regard, we have not determined what
course of action we would  propose to the Board.  In any event,  any such action
would have to be taken by the Board  consistent with its fiduciary duties to the
stockholders of the Company

ADOPTION  OF THE  PROPOSALS  IS  REQUIRED  TO  REMOVE  FOUR  DIRECTORS  FROM THE
COMPANY'S CURRENT BOARD OF DIRECTORS,  TO ADD ONE NOMINEE TO THE COMPANY'S BOARD
OF  DIRECTORS.  ACCORDINGLY,  WE URGE YOU TO  PROMPTLY  SIGN,  DATE AND MAIL THE
ENCLOSED  WHITE CONSENT CARD.  FAILURE TO SIGN AND RETURN YOUR CONSENT WILL HAVE
THE SAME EFFECT AS WITHHOLDING OR ABSTAINING ON THE CONSENT PROPOSALS.

                                CONSENT PROCEDURE

     Article I, Section 1.9 of the Amended and  Restated  By-Laws of the Company
(the  "Bylaws")  state that the Board of Directors may fix a record date,  which
record  date shall not  precede  the date upon which the  resolution  fixing the
record  date is adopted by the Board of  Directors,  and which date shall not be
more than ten days  after the date upon which the  resolution  fixing the record
date is adopted by the Board of  Directors.  If no record date has been fixed by
the Board of Directors, the record date for determining stockholders entitled to
consent to corporate  action in writing without a meeting,  when no prior action
by the Board of Directors is required by law, shall be the first date on which a
signed written consent setting forth the action taken or proposed to be taken is
delivered  to the Company by delivery to its  registered  office in the State of
Delaware, its principal place of business, or an officer or agent of the Company
having custody of the book in which  proceedings of meetings of stockholders are
recorded.  Delivery made to the Company's  registered office shall be by hand or
by certified or registered mail, return receipt requested. If no record date has
been fixed by the Board of Directors  and prior action by the Board of Directors
is required by law,  the record date for  determining  stockholders  entitled to
consent to corporate  action in writing  without a meeting shall be at the close
of business  on the day on which the Board of  Directors  adopts the  resolution
taking such prior action.

     Section  228  of  the  DGCL  states  that,   unless  the   certificate   of
incorporation of a Delaware corporation otherwise provides,  any action required
to  be  taken  at  any  annual  or  special  meeting  of  stockholders  of  that
corporation, or any action that may be taken at any annual or special meeting of
those  stockholders,  may be taken  without a meeting,  without prior notice and
without a vote, if a consent or consents in writing, setting forth the action so
taken,  is signed by the holders of  outstanding  stock having not less than the
minimum number of votes that would be necessary to authorize or take that action
at a meeting at which all shares  entitled  to vote  thereon  were  present  and
voted,  and those  consents are delivered to the  corporation by delivery to its
registered office in Delaware,  its principal place of business or an officer or
agent of the  corporation  having  custody of the book in which  proceedings  of
meetings  of  stockholders  are  recorded.  Delivery  made  to  a  corporation's
registered  office shall be by hand or by certified or registered  mail,  return
receipt  requested.  Consents  must also bear the date of the  signature  of the
stockholder  who  signs  the  written  consent.  The  Company's  certificate  of
incorporation,  as  amended,  does not  prohibit,  and  therefore  permits,  the
Company's  stockholders to act by written  consent.  In addition,  the Company's
Bylaws permit the Company's stockholders to act by written consent.

     Section  213(b) of the DGCL provides  that the record date for  determining
the  stockholders  of a Delaware  corporation  entitled to consent to  corporate
action in writing without a meeting,  when no prior action by the  corporation's
board of directors  is required and the board has not fixed a record date,  will
be the first date on which a signed  written  consent  setting  forth the action
taken or proposed to be taken is delivered to the corporation by delivery to its
registered office in Delaware,  its principal place of business or an officer or
agent of the  corporation  having  custody of the book in which  proceedings  of
meetings of the  stockholders  are recorded.  Delivery  made to a  corporation's
registered  office shall be by hand or by certified or registered  mail,  return
receipt requested. This rule has not been modified by the Company's bylaws.

     According to the Company's  press release dated October 3, 2006,  the Board
of Directors  has fixed  October 3, 2006 (the "Record  Date") as the record date
for the determination of the Company's stockholders who are entitled to execute,
withhold or revoke consents relating to this solicitation.

     According to the Company's latest Schedule 14A filed with the SEC on August
31, 2006, the Company had 84,283,155  Shares  outstanding as of August 31, 2006.
Cumulative voting is not permitted.  The actual number of consents  necessary to
effect the  Proposals  will  depend on the number of  outstanding  Shares on the
Record Date.

     Each Proposal  will become  effective  only if properly  executed and dated
unrevoked consents to that Proposal are returned by holders of a majority of the
outstanding  Shares return signed written  consents  within 60 days of the first
date on which a  signed  written  consent  setting  forth  the  action  taken or
proposed to be taken is

                                      -17-



delivered to the Company.  Thus, this 60 day period will begin on the first date
that any stockholder of the Company  delivers the first validly executed consent
or consents to the Company. High River, the record owner of 500 Shares,  intends
to deliver  its validly  executed  consent,  with  respect to such Shares to the
Company on October 19,  2006.  In the event that High  River's  consent  when so
delivered is the earliest  validly executed and received consent by the Company,
the 60 day period will begin on October 19, 2006.

     The  failure  to sign and  return a consent  will  have the same  effect as
voting against the Proposals.

     If your Shares are registered in your own name,  please sign, date and mail
the enclosed WHITE consent card to the Icahn Parties,  c/o D.F. King & Co., Inc.
in the  post-paid  envelope  provided.  If your Shares are held in the name of a
brokerage  firm,  bank  nominee or other  institution,  only it can sign a WHITE
consent  card with  respect  to your  Shares  and only on  receipt  of  specific
instructions from you.  Accordingly,  you should contact the person  responsible
for your  account and give  instructions  for a WHITE  consent card to be signed
representing your Shares. We urge you to confirm in writing your instructions to
the  person  responsible  for  your  account  and to  provide  a copy  of  those
instructions  to Icahn  Parties c/o D.F. King & Co., Inc. so we will be aware of
all  instructions  given and can attempt to ensure that those  instructions  are
followed.

     If you have any  questions  or require any  assistance  in  executing  your
consent, please call: D.F. King & Co., Inc. at (800) 714-3313. Banks and brokers
may call collect at (212) 269-5550.

     If the Proposals become effective as a result of this consent solicitation,
prompt notice will be given under Section 228(e) of the DGCL to stockholders who
have not executed consents.

     We will bear the costs of this consent solicitation. The consents are being
solicited  in  accordance  with the  applicable  provisions  of the DGCL.  To be
effective,  the requisite  consents  must be delivered to the Company  within 60
days of the earliest dated consent delivered to the Company.

                              REVOCATION PROCEDURE

     An executed  consent  card may be revoked at any time by properly  marking,
dating,  signing and  delivering a written  revocation  before the time that the
action  authorized by the  previously  executed  consent  becomes  effective.  A
revocation  may be in any written  form validly  signed by the record  holder as
long as it  clearly  states  that the  consent  previously  given  is no  longer
effective. The delivery of a later dated consent card that is properly completed
will  constitute a revocation  of any earlier  consent.  The  revocation  may be
delivered  either to the Company or to the Icahn  Parties,  c/o D.F. King & Co.,
Inc. at 48 Wall  Street,  New York,  NY 10005.  We will  promptly  transmit  all
revocations  to the Company.  Although a revocation is effective if delivered to
the Company,  we request that either the original or  photostatic  copies of all
revocations  of consents be mailed or delivered to D.F.  King & Co., Inc. at the
address set forth  above,  so that we will be aware of all  revocations  and can
more  accurately  determine  if and when valid  consents  of a  majority  of the
outstanding  Shares  to the  Proposals  have  been  received  for  this  consent
solicitation.


                              SPECIAL INSTRUCTIONS

     If you were a holder of record of the  Shares on the first  date on which a
signed  written  consent  setting  forth  the  action  proposed  to be  taken is
delivered to the Company,  you may elect to consent to,  withhold  consent to or
abstain  with  respect to each  Proposal  by marking  the  "CONSENT,"  "WITHHOLD
CONSENT"  or  "ABSTAIN"  box, as  applicable,  underneath  each  Proposal on the
accompanying WHITE consent card and signing, dating and returning it promptly in
the enclosed post-paid  envelope.  In addition,  you may withhold consent to the
removal of any individual  director or the election of any individual Nominee by
writing that person's name on the consent card.

                                      -18-



     IF A STOCKHOLDER  EXECUTES AND DELIVERS A WHITE CONSENT CARD,  BUT DOES NOT
CHECK A BOX MARKED  "CONSENT,"  "WITHHOLD  CONSENT" OR "ABSTAIN" FOR A PROPOSAL,
THAT STOCKHOLDER WILL BE DEEMED TO HAVE CONSENTED TO THAT PROPOSAL,  EXCEPT THAT
THE  STOCKHOLDER  WILL NOT BE DEEMED TO CONSENT TO EITHER 1) THE  REMOVAL OF ANY
DIRECTOR  WHOSE NAME IS WRITTEN IN THE SPACE THE  APPLICABLE  INSTRUCTION TO THE
REMOVAL  PROPOSAL  PROVIDES ON THE CARD OR 2) THE ELECTION OF THE NOMINEE  WHOSE
NAME IS WRITTEN IN THE SPACE THE APPLICABLE INSTRUCTION TO THE ELECTION PROPOSAL
PROVIDES ON THE CARD.

     YOUR CONSENT IS IMPORTANT.  PLEASE SIGN AND DATE THE ENCLOSED WHITE CONSENT
CARD AND RETURN IT IN THE ENCLOSED POST-PAID  ENVELOPE  PROMPTLY.  YOU MUST DATE
YOUR CONSENT IN ORDER FOR IT TO BE VALID.  FAILURE TO SIGN, DATE AND RETURN YOUR
CONSENT WILL HAVE THE SAME EFFECT AS VOTING AGAINST THE PROPOSALS.

     If your Shares are held in the name of a brokerage  firm,  bank  nominee or
other  institution,  only it can execute a consent  with respect to those Shares
and only on receipt of specific  instructions from you. Thus, you should contact
the person  responsible  for your  account and give  instructions  for the WHITE
consent  card to be signed  representing  your  Shares.  You  should  confirm in
writing your instructions to the person responsible for your account and provide
a copy of those  instructions to the Icahn Parties c/o D.F. King & Co., Inc., 48
Wall Street,  New York, NY 10005,  so that we will be aware of all  instructions
given and can attempt to ensure that those instructions are followed.

     If you have any  questions  or require any  assistance  in  executing  your
consent, please call:
