Dear Fellow Stockholders of ImClone Systems Incorporated:

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

We are  requesting  that you act by written  consent to remove the six directors
named  below  from the  Company's  twelve  member  board  and to fill two of the
resulting vacancies with the person also named below.

We are soliciting your written consent to approve the following:

     o    the removal without cause of David M. Kies, William W. Crouse, 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 (the "Nominee");

Each of the two Proposals is conditioned  upon the approval by the  stockholders
of the Company of the other Proposal.  Thus, we will not be seeking the removal
of the six  persons  named  above  unless  the  stockholders  also  approve  the
appointment of the Nominee.

Our  Nominee,  together  with the 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. We expect that the
reconstituted  Board will proceed  rapidly to find a permanent  Chief  Executive
Officer.

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.

RETURNING THE ENCLOSED WHITE CONSENT CARD TODAY.

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.

consent,  as set forth on your WHITE  consent card, in favor of each Proposal as
described in the accompanying consent statement.

                         CONSENT SOLICITATION STATEMENT
                                       OF
                                  CARL C. ICAHN
                                ALEXANDER DENNER
                               BARBERRY CORP. AND
                         HIGH RIVER LIMITED PARTNERSHIP

Carl C. Icahn,  Alexander  J.  Denner,  Barberry  Corp.  and High River  Limited
Partnership  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 David M. Kies,  William W. Crouse,  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 to serve as  members  of the  Board of the  Company
("Proposal 2");

Each of the two Proposals is conditioned  upon the approval by the  stockholders
of the Company of the other Proposal.  Thus, we will not be seeking the removal
of the six  persons  named  above  unless  the  stockholders  also  approve  the
appointment of the Nominee.

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 [ ].

The purpose of the consent  solicitation is to remove six 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,
BARBERRY CORP. AND HIGH RIVER LIMITED PARTNERSHIP 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 [ ].

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 [ ], 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"),
     and High River Limited  Partnership,  a Delaware limited partnership ("High
     River") (Mr. Icahn, Dr. Denner, High River and Barberry,  collectively, the
     "Icahn  Parties").  Barberry and High River 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 Investments LLC, a
     Delaware  limited  partnership  ("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.
     Neither  Mr.  Icahn  or Dr.  Denner  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 six 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. Each of the two Proposals is  conditioned  upon
     the  approval by the  stockholders  of the Company of the other  Proposal.
     Thus,  we will not be seeking the  removal of the six  persons  named above
     unless the stockholders also approve the appointment of the Nominee.

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.


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.  If the Board of  Directors  of the
Company sets a record date for  stockholders  only  stockholders as of that date
are  eligible  to  give  written  consent.  Such  date  may be the  date  of the
resolution  fixing the record  date but may not be more then ten days after such
resolution. If no record  date is fixed by the  Board, the date for  determining
stockholders  entitled  to  consent  shall be the  first  date on which a signed
written consent is delivered to the Company,  please see "Consent  Procedure" on
page ____.

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 six  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  (___),  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 ____.

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?

A:   An  executed  consent  card may be  revoked  at any time  before the action
     authorized by the executed  consent becomes  effective by marking,  dating,
     signing and  delivering a written  revocation.  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.  A later
     dated consent card that is properly completed and delivered will revoke any
     earlier  dated  consent.  The  revocation  may be  delivered  either to the
     Company or to the Icahn Parties, c/o D.F. King & Co., Inc., 48 Wall Street,
     New York, NY 10005. We will promptly  deliver any revocations we receive 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.

Q:   WHOM SHOULD I CALL IF I HAVE QUESTIONS ABOUT THE SOLICITATION?

A:   Please call D.F. King & Co., Inc. at (800) 714-3313 (toll-free).  Banks and
     brokers may call collect at (212) 269-5550.

AGREEMENTS WITH NOMINEE

with the Nominee: Dr. Peter S. Liebert. The Nominee Agreement is provides, among
other things, as follows:

     o    The Nominee  acknowledges  that he has agreed to stand for appointment
          as a director of the Company in connection with a consent solicitation
          to remove six directors of the Company and to appoint the Nominee.

     o    High River has agreed to pay the costs of the consent solicitation.

          misconduct.

                             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.

IT IS EXPECTED  THAT OUR CONSENTS  WILL BE DELIVERED OT THE COMPANY ON OCTOBER ,
2006.

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 SIX 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.


                                 PROPOSAL NO. 1

   REMOVAL OF DAVID M. KIES, WILLIAM W. CROUSE, VINCENT T. DEVITA, JR., M.D.,
             JOHN A. FAZIO, JOSEPH L. FISCHER AND WILLIAM R. MILLER

     This Proposal seeks the removal without cause of David M. Kies,  William W.
Crouse,  Vincent T.  DeVita,  Jr.,  M.D.,  John A. Fazio,  Joseph L. Fischer and
William R. Miller from the current  Board.  This Proposal also seeks the removal
of 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 the Proposals to fill any  newly-created
directorship  or  vacancy  on  the  Board.  This  is  intended  to  address  the
possibility  that the current  directors might try to add directors to the Board
who are aligned with them.

     Section  2.2 of Article  II of the  Company's  bylaws  states  that  "[a]ny
director or the entire Board of  Directors  may be removed,  with cause,  by the
holders of a majority  of the shares  then  entitled  to vote at an  election of
directors"  (the "Bylaw  Provision").  Section  141(k) of the  Delaware  General
Corporation Law ("Section  141(k)")  provides that "[a]ny director or the entire
board of directors may be removed,  with or without  cause,  by the holders of a
majority  of the shares  entitled  to vote at an  election  of  directors"  with
certain  exceptions  that are not  relevant  to  ImClone.  We believe  the Bylaw
Provision  is  invalid  to the  extent  it  purports  to limit  the right of the
stockholders to remove  directors only for "cause" because it is contrary to the
above-quoted  provision  of Section  141(k).  We have  received  advice from our
Delaware  counsel  confirming  our  belief.  As a result,  we will be seeking to
remove the six directors noted above without cause.

Each of the two Proposals is conditioned  upon the approval by the  stockholders
of the Company of the other  Proposal.  Thus, we will not be seeking the removal
of the six  persons  named  above  unless  the  stockholders  also  approve  the
appointment of the Nominee.


      WE URGE YOU TO APPROVE THE REMOVAL OF SIX OF THE COMPANY'S DIRECTORS.



                                 PROPOSAL NO. 2

                               ELECTION OF NOMINEE

     Proposal  2 seeks to  appoint  Peter S.  Liebert,  M.D.  to fill one of the
vacancies  resulting from Proposal 1. Dr. Liebert,  has consented to being named
as a Nominee  and to serve as a  director,  if  appointed.  If  appointed,  such
Nominee will serve until the next annual meeting of the Company's  stockholders,
and until his successor  shall have been duly elected and qualified or until his
earlier death, resignation or removal.

Each of the two Proposals is conditioned  upon the approval by the  stockholders
of the Company of the other  Proposal.  Thus, we will not be seeking the removal
of the six  persons  named  above  unless  the  stockholders  also  approve  the
appointment of the Nominee.

            WE URGE YOU TO CONSENT TO THE APPOINTMENT OF THE NOMINEE.






                                VOTING SECURITIES

     The Shares  constitute the voting securities of the Company for purposes of
this consent solicitation.. According to the Company's latest Schedule 14A filed
with the SEC on August 31,  2006,  the Company had  84,283,155  Shares of common
stock outstanding as of August 15, 2006. Cumulative voting is not permitted.


                                APPRAISAL RIGHTS

     The  Company's  stockholders  are  not  entitled  to  appraisal  rights  in

                            SOLICITATION OF CONSENTS

     The  members  and agents of the Icahn  Parties  and the Nominee may solicit
consents.  Consents  will  be  solicited  by  mail,  advertisement,   telephone,

receive additional compensation for their solicitation efforts.

     In addition, we have retained D.F. King & Co., Inc. ("D.F. King") to assist
in this consent  solicitation,  for which  services D.F. King will be paid a fee
not to exceed  $150,000.  D.F. King will also be reimbursed  for its  reasonable
out-of-pocket  expenses.  We have also agreed to  indemnify  D.F.  King  against
certain  liabilities and expenses,  including  certain  liabilities and expenses
under the federal  securities  laws.  It is  anticipated  that between 75 to 100
persons will be employed by D.F. King to solicit stockholders.

     Banks, brokers,  custodians,  nominees and fiduciaries will be requested to
forward solicitation  material to beneficial owners of Shares. We will reimburse
banks,  brokers,  custodians,  nominees  and  fiduciaries  for their  reasonable
expenses for sending solicitation material to the beneficial owners.

     Our  estimate  of the total cost to be  incurred  in  connection  with this
consent  solicitation,  [other than any severance or employment  related  costs]
described  below, is $[ ]. To date, $[ ] million has been incurred in connection
with  this  consent  solicitation.  We will  bear  the  costs  of  this  consent
solicitation.  Costs  related  to  the  solicitation  of  consents  may  include
expenditures  for  attorneys,   investment   bankers,   accountants,   printing,
advertising, postage and related expenses and fees.



                                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 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 delivered to the Company. The failure to sign and return
a consent will have the same effect as voting against the Proposals. Each of the
two  Proposals  is  conditioned  upon the  approval by the  stockholders  of the
Company of the other Proposal.  Thus, we will not be seeking the removal of the
six persons named above unless the stockholders  also approve the appointment of
the Nominee.


     If your Shares are registered in your own name,  please sign, date and mail
the enclosed WHITE consent card to 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 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.

     Each  of  the  two  Proposals  is  conditioned  upon  the  approval  by the
stockholders of the Company of the other Proposal. Thus, we will not be seeking
the removal of the six persons named above unless the stockholders  also approve
the appointment of the Nominee.


     IF A STOCKHOLDER  EXECUTES AND DELIVERS A WHITE CONSENT CARD,  BUT DOES NOT

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
