EXHIBIT 10.30  IMCLONE SYSTEMS INCORPORATED  CHANGE-IN-CONTROL PLAN  1.0PURPOSE
OF PLAN  1.1Purpose.  The purpose of the ImClone Systems
Incorporated Change-in-Control Plan (the Plan) is to:  (a)retain
certain highly qualified individuals as employees of ImClone Systems
Incorporated and/or its subsidiaries (the Company);  (b)maintain
the focus of such employees on the business of the Company and to mitigate the distractions
caused by the possibility that the Company may be the target of an acquisition strategy;
and  (c)provide
certain benefits to such employees if a change in control of the Company occurs
and/or any employees employment is terminated in connection with such change
in control.  The Plan is intended to qualify as an employee
benefit plan (as such term is defined under Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended (ERISA)) and
accordingly will be subject to ERISA.  In
addition, the Plan is intended to qualify as a top-hat plan (as such term is
commonly used under the ERISA regulations promulgated by the U.S. Department of
Labor) since it is intended to provide benefits only to a select group of
management or highly compensated employees of the Company.  2.0DEFINITIONS  The
following terms shall have the following meanings unless the context indicates
otherwise:  2.1Beneficiary shall mean a beneficiary
designated in writing by a Participant to receive any Change-in-Control
Benefits in accordance with Sections 5 or 6 below.  If no beneficiary is designated by the
Participant, then the Participants estate shall be deemed to be the
Participants Beneficiary.  2.2Board shall mean the Board of Directors of the Company.  2.3Bonus shall mean the 3-year average of the actual annual
bonuses paid to the Participant during the 36-month period immediately
preceding the Change-in-Control Date, with such amount increased (if
applicable) to take into account any elective or mandatory deferrals.  For a Participant who has not been employed
by the Company for the full 36-month period prior to the Change-in-Control
Date, the average annual bonus amount shall be calculated based on the number
of full years of employment.  For a
Participant who has not been employed long enough to receive an annual bonus,
the annual bonus amount shall be equal to the target annual bonus.  2.4Cause shall mean  unless otherwise defined in an
employment agreement between the Participant and the Company or Subsidiary 
the occurrence of any of the following:  (1)an
indictment of the Participant involving a
felony or a misdemeanor involving moral turpitude; or  (2)willful misconduct or gross negligence by the
Participant resulting, in either case, in harm to the Company or any
Subsidiary; or  1


(3)failure by the Participant to carry out the
directions of the Board or the Participants immediate supervisor, as the case
may be; or  (4)fraud,
embezzlement, theft or dishonesty by the Participant against the Company or any
Subsidiary or a material violation by the
Participant of a policy or procedure of the Company, resulting, in any case, in
harm to the Company or any Subsidiary.  2.5Change in Control shall mean the occurrence of one of the

is named as a nominee for director, without objection to such nomination) shall
be an Incumbent Director; provided, however, that no individual initially
elected or nominated as a director of the Company as a result of an actual or
threatened election contest with respect to directors or as a result of any other
actual or threatened solicitation of proxies by or on behalf of any person
other than the Board shall be an Incumbent Director;  (2)any person
(as such term is defined in Section 3(a)(9) of the Securities
Exchange Act of 1934 (the Exchange Act) and as used in Sections 13(d)(3) and
14(d)(2) of the Exchange Act) is or becomes, after the Effective Date, a beneficial
owner (as defined in Rule 13d-3 under the Exchange Act), directly or
indirectly, of securities of the Company representing 40% or more of the
combined voting power of the Companys then outstanding securities eligible to
vote for the election of the Board (the Company Voting Securities); provided,
however, that an event described in this Section 2.5(2) shall not be

outstanding voting common equity interests immediately prior to such
liquidation and such ongoing entity assumes all existing obligations of the
Company under this Plan.  Notwithstanding the foregoing, a Change in Control of
the Company shall not be deemed to occur solely because any person acquires
beneficial ownership of more than 40% of the Company Voting Securities as a
result of the acquisition of Company Voting Securities by the Company which
reduces the number of Company Voting Securities outstanding; provided, that, if

is used under Code Section 280G) exceeds 299.99% of the base amount (as
such term is used under Code Section 280G) (the Safe Harbor Amount) by
less than 10% of the Safe Harbor Amount, then the parachute payment shall be
reduced to the Safe Harbor Amount, with the Participant determining in his or
her sole discretion which portion of the aggregate parachute payment shall be
so reduced; or  (b)if the aggregate parachute payment exceeds the
Safe Harbor Amount by 10% or more of the Safe Harbor Amount, then the Company
shall pay to the Participant a tax gross-up payment so that after
payment by the Participant of all federal, state, and local excise, income,
employment, Medicare and any other taxes (including any related penalties and
interest) resulting from the payment of the parachute payments and the tax
gross-up payments to the Participant by the Company, the Participant retains on
an after-tax basis an amount equal to the amount that the Participant would
have retained had he or she not been subject to the Parachute Excise Tax.  9.3No Guarantee of Tax
Consequences.  No person connected
with the Plan in any capacity, including, but not limited to, the Company and
any Subsidiary and their directors, officers, agents and employees makes any
representation, commitment, or guarantee that any tax treatment, including, but
not limited to, federal, state and local income, estate and gift tax treatment,
will be applicable with respect to amounts deferred under the Plan, or paid to
or for the benefit of a Participant under the Plan, or that such tax treatment
will apply to or be available to a Participant on account of participation in
the Plan.  10.0TERM OF PLAN; AMENDMENT AND TERMINATION OF PLAN  10.1Term of Plan.  The Plan shall be effective as of the
Effective Date and shall remain in effect until the Board terminates the Plan.  10.2Amendment of Plan.  The Plan may be amended by the Board at any
time with or without prior notice; provided, however,
that the Plan shall not be amended on a Change-in-Control Date or during the
3-year period following such Change-in-Control Date.  10.3Termination of Plan. 
The Plan may be terminated or suspended by the Board at any time with or
without prior notice; provided, however,
that the Plan shall not be terminated or suspended on a Change-in-Control Date
or during the 3-year period following such Change-in-Control Date.  10.4No Adverse Effect.  If
the Plan is amended, terminated, or suspended in accordance with Sections 10.2
or 10.3 above, such action shall not adversely affect the benefits of any
Participant.  11.0MISCELLANEOUS  11.1Offset.  Change-in-Control Benefits shall be reduced
by any payment or benefit made or provided by the Company or any Subsidiary to
the Participant pursuant to (i) any severance plan, program, policy or
arrangement of the Company or any Subsidiary not otherwise referred to in the
Plan, (ii) any employment agreement between the Company or any Subsidiary
and the Participant, and (iii) any federal, state or local statute, rule,
regulation or ordinance.  11.2No Right, Title, or
Interest in Company Assets. 
Participants shall have no right, title, or interest whatsoever in or to
any assets of the Company or any investments which the Company may make to aid
it in meeting its obligations under the Plan. 
Nothing contained in the Plan, and no action taken pursuant to its
provisions, shall create or be construed to create a trust of any kind, or a  11


fiduciary
relationship between the Company and any Participant, Beneficiary, legal
representative or any other person.  To
the extent that any person acquires a right to receive payments from the
Company under the Plan, such right shall be no greater than the right of an
unsecured general creditor of the Company. 
Subject to this Section 11.2, all payments to be made hereunder
shall be paid from the general funds of the Company and no special or separate
fund shall be established and no segregation of assets shall be made to assure
payment of such amounts; provided, however,
that the Company may establish a
grantor trust to provide for the payment of the benefits under the Plan of
which the Company is the grantor within the meaning of subpart E, part I,
subchapter J, chapter 1, subtitle A of the Code and under which the assets held
by such trust will be subject to the claims of the Companys general creditors
under federal and state law in the event of the Companys insolvency.  11.3No Right to Continued
Employment.  The Participants
rights, if any, to continue to serve the Company as an employee shall not be
enlarged or otherwise affected by his or her designation as a Participant under
the Plan, and the Company or the applicable Subsidiary reserves the right to
terminate the employment of any employee at any time.  The adoption of the Plan shall not be deemed
to give any employee, or any other individual any right to be selected as a
Participant or to continued employment with the Company or any Subsidiary.  11.4Other Rights.  The Plan shall not affect or impair the
rights or obligations of the Company or a Participant under any other written
plan, contract, arrangement, or pension, profit sharing or other compensation
plan.  11.5Governing Law.  The Plan shall be governed by and construed
in accordance with the laws of the State of Delaware without reference to
principles of conflict of laws, except as superseded by ERISA and other
applicable federal law.  11.6Severability.  If any term or condition of the Plan shall be
invalid or unenforceable to any extent or in any application, then the
remainder of the Plan, with the exception of such invalid or unenforceable
provision, shall not be affected thereby and shall continue in effect and
application to its fullest extent.  11.7Incapacity.  If the Committee determines that a
Participant or a Beneficiary is unable to care for his or her affairs because
of illness or accident or because he or she is a minor, any benefit due the
Participant or Beneficiary may be paid to the Participants spouse or to any
other person deemed by the Committee to have incurred expense for such
Participant (including a duly appointed guardian, committee or other legal
representative), and any such payment shall be a complete discharge of the
Companys obligation hereunder.  11.8Transferability of
Rights.  The Company shall have the
unrestricted right to transfer its obligations under the Plan with respect to
one or more Participants to any person, including, but not limited to, any
purchaser of all or any part of the Companys business.  No Participant or Beneficiary shall have any
right to commute, encumber, transfer or otherwise dispose of or alienate any
present or future right or expectancy which the Participant or Beneficiary may
have at any time to receive payments of benefits hereunder, which benefits and
the right thereto are expressly declared to be non-assignable and
nontransferable, except to the extent required by law.  Any attempt to transfer or assign a benefit,
or any rights granted hereunder, by a Participant or the spouse of a
Participant shall, in the sole discretion of the Committee (after consideration
of such facts as it deems pertinent), be grounds for terminating any rights of
the Participant or Beneficiary to any portion of the Plan benefits not
previously paid.  [REMAINDER OF PAGE INTENTIONALLY

EXHIBIT B  RELEASE  This
RELEASE (Release) dated as of this            day
of
                    ,
20   between ImClone Systems Incorporated, a Delaware
corporation (the Company), and
                    
(the Employee).  WHEREAS,
the Employee is a participant in the Companys Change-in-Control Plan (the Plan);
and  WHEREAS,
the Employees employment with the Company (has been) (will be) terminated
effective
                            ;
and  WHEREAS,
pursuant to Section 7.1 of the Plan, the Employee is entitled to certain
compensation and benefits upon such termination, contingent upon the execution
of this Release;  NOW,
THEREFORE, in consideration of the premises and mutual agreements contained
herein and in the Plan, the Company and the Employee agree as follows:  1.The
Employee, on [his/her] own behalf and on behalf of [his/her] heirs, estate and
beneficiaries, does hereby release the Company, and any of its Subsidiaries or
affiliates, and each past or present officer, director, agent, employee,
shareholder, and insurer of any such entities, from any and all claims made, to
be made, or which might have been made of whatever nature, whether known or
unknown, from the beginning of time, including those that arose as a
consequence of [his/her] employment with the Company, or arising out of the
severance of such employment relationship, or arising out of any act committed
or omitted during or after the existence of such employment relationship, all
up through and including the date on which this Release is executed, including,
but not limited to, those which were, could have been or could be the subject
of an administrative or judicial proceeding filed by the Employee or on
[his/her] behalf under federal, state or local law, whether by statute,
regulation, in contract or tort, and including, but not limited to, every claim
for front pay, back pay, wages, bonus, fringe benefit, any form of
discrimination (including but not limited to, every claim of race, color, sex,
religion, national origin, disability or age discrimination), wrongful
termination, emotional distress, pain and suffering, breach of contract,
compensatory or punitive damages, interest, attorneys fees, reinstatement or
reemployment.  If any court rules that
such waiver of rights to file, or have filed on [his/her] behalf, any
administrative or judicial charges or complaints is ineffective, the Employee
agrees not to seek or accept any money damages or any other relief upon the
filing of any such administrative or judicial charges or complaints.  The Employee relinquishes any right to future
employment with the Company and the Company shall have the right to refuse to
re-employ the Employee without liability. 
The Employee acknowledges and agrees that even though claims and facts
in addition to those now known or believed by [him/her] to exist may
subsequently be discovered, it is [his/her] intention to fully settle and
release all claims [he/she] may have against the Company and the persons and
entities described above, whether known, unknown or suspected.  2.The
Employee acknowledges that [he/she] has been provided at least 21 days to
review the Release and has been advised to review it with an attorney of
[his/her] choice.  In the event the
Employee elects to sign this Release prior to the end of this 21-day period,
[he/she] agrees that it is a knowing and voluntary waiver of [his/her] right to
wait the full 21 days.  The Employee
further understands that [he/she] has 7 days after the signing hereof to revoke
it by so notifying the Company in writing, such notice to be received by
                     
within the 7-day period.  The Employee
further acknowledges that [he/she] has carefully read this Release, and knows
and understands its contents and its binding legal effect.  The Employee acknowledges that by signing
this Release, [he/she] does so of [his/her] own free will and act and that it
is [his/her] intention that [he/she] be legally bound by its terms.  14
