NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)


(1) BASIS OF PREPARATION

The consolidated financial statements of ImClone Systems Incorporated
("ImClone Systems" or the "Company") as of June 30, 2002 and for the three and
six months ended June 30, 2002 and 2001 are unaudited. In the opinion of
management, these unaudited financial statements include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation. These financial statements should be read in conjunction with the
audited financial statements and notes thereto included in the Company's Annual
Report on Form 10-K for the year ended December 31, 2001, as filed with the
Securities and Exchange Commission ("SEC").

Results for the interim periods are not necessarily indicative of results
for the full years.

Pursuant to the guidance in Emerging Issues Task Force Issue No. 01-14,
Income Statement Characterization of Reimbursements Received for "Out-of-Pocket"
Expenses Incurred ("EITF No. 01-14"), the Company changed its classification for
corporate partner reimbursements effective January 1, 2002 to characterize such
reimbursements received for research and development and marketing expenses
incurred as collaborative agreement revenue in the consolidated statements of
operations. Prior to January 1, 2002, the Company characterized such
reimbursements as a reduction of expenses in the consolidated statements of
operations. As prescribed in EITF No. 01-14, all comparative financial
statements for prior periods have been reclassified to comply with this
guidance.

============ ============


The Company is building a second commercial manufacturing facility
adjacent to its new product launch manufacturing facility in Somerville, New
Jersey. This new facility will be a multi-use facility with capacity of up to
110,000 liters (working volume). The 250,000 square foot facility will cost
approximately $233,000,000, and is being built on land purchased in December
2000. The actual cost of the new facility may change depending upon various
factors. The Company incurred approximately $52,617,000, (included in
construction in progress above) excluding capitalized interest of approximately
$1,234,000, in conceptual design, engineering and pre-construction costs through
June 30, 2002. Through July 22, 2002, committed purchase orders totaling
approximately $40,217,000 have been placed for subcontracts and equipment
related to this project. In addition, $22,770,000 in engineering, procurement,
construction management and validation costs were committed.

In January 2002, the Company purchased real estate consisting of a
7.5-acre parcel of land located adjacent to the Company's product launch
manufacturing facility and pilot facility in Somerville, New Jersey. The real
estate includes an existing 50,000 square foot building, 40,000 square feet of
which is warehouse space and 10,000 square feet of which is office space. The
purchase price for the property and building was approximately $7,020,000, of
which approximately $1,125,000 related to the purchase of the land and
approximately $5,895,000 related to the purchase of the building. The Company
intends to use this property for warehousing and logistics for its Somerville
campus.



Page 4

On May 20, 2002, the Company purchased real estate consisting of a
6.94-acre parcel of land located across the street from the Company's product
launch manufacturing facility in Somerville, New Jersey. The real estate
includes an existing 46,000 square feet of office space. The purchase price for
the property was approximately $4,515,000, of which approximately $1,041,000 was
related to the purchase of the land and approximately $3,474,000 was related to
the purchase of the building. The Company intends to use this property as the
administrative building for the Somerville campus. As of June 30, 2002, the
Company has incurred approximately $422,000 for the retrofit of this facility.
The total cost for the retrofit will be approximately $5,187,000.

The process of preparing consolidated financial statements in accordance
with accounting principles generally accepted in the United States of America
requires the Company to evaluate the carrying values of its long-lived assets.
The recoverability of the carrying values of the Company's product launch
manufacturing facility, its second commercial manufacturing facility and its
warehousing and logistics facility will depend on (1) receiving FDA approval of
our interventional therapeutic product candidate for cancer, ERBITUX((TM)), (2)
receiving FDA approval of the manufacturing facilities and (3) the Company's
ability to earn sufficient returns on ERBITUX. Based on management's current
estimates, the Company expects to recover the carrying value of such assets.

(3) MANUFACTURING CONTRACT SERVICES

In December 1999, the Company entered into a development and manufacturing
services agreement with Lonza Biologics PLC ("Lonza"). This agreement was
amended in April 2001 to include additional services. Under the agreement, Lonza
was responsible for process development and scale-up to manufacture ERBITUX in
bulk form under current Good Manufacturing Practices ("cGMP") conditions. These
steps were taken to assure that the manufacturing process would produce bulk
material that conforms with the Company's reference material. The Company did
not incur any costs associated with this agreement during the three months ended
June 30, 2002 and 2001. Approximately $38,000 and $3,600,000 was incurred in the
six months ended June 30, 2002 and 2001, respectively, and $7,068,000 from
inception through June 30, 2002. As of June 30, 2002, Lonza has completed its
responsibilities under the development and manufacturing services agreement.

In September 2000, the Company entered into a three-year commercial
manufacturing services agreement with Lonza relating to ERBITUX. This agreement
was amended in June 2001 and again in September 2001 to include additional
services. The total cost for services to be provided under the three-year
commercial manufacturing services agreement is approximately $87,050,000. The
Company has incurred approximately $7,410,000 and $3,075,000 in the three months
ended June 30, 2002 and 2001, respectively, and $14,528,000 and $4,875,000 in
the six months ended June 30, 2002 and 2001, respectively, and $24,840,000 from
inception through June 30, 2002 for services provided under the commercial
manufacturing services agreement.

Under the December 1999 and September 2000 agreements, Lonza is
manufacturing ERBITUX at the 5,000 liter scale under cGMP conditions and is
delivering it to the Company over a term ending no later than December 2003.
The costs associated with both of these agreements are included in research and
development expenses when incurred and will continue to be so classified until
such time as ERBITUX may be approved for sale or until the Company obtains
obligations from its corporate partners to purchase such product. In the event
of such approval or obligations from its corporate partners, the subsequent
costs associated with manufacturing ERBITUX for commercial sale will be
included in inventory and expensed when sold. In the event the Company
terminates the commercial manufacturing services agreement without cause, the
Company will be required to pay 85% of the stated costs for each of the first
ten batches cancelled, 65% of the stated costs for each of the next ten batches
cancelled and 40% of the stated costs for each of the next six batches
cancelled. The batch cancellation provisions for certain additional batches
that we are committed to purchase require the Company to pay 100% of the stated
costs of cancelled batches scheduled within six months of the cancellation, 85%
of the stated costs of cancelled batches scheduled between six and twelve
months following the cancellation and 65% of the stated costs of cancelled
batches scheduled between twelve and eighteen months following the
cancellation. These amounts are subject to mitigation should Lonza use its
manufacturing capacity caused by such termination for another customer. At June
30, 2002, the estimated remaining future commitments under the amended
commercial manufacturing services agreement are $38,160,000 in 2002 and
$24,050,000 in 2003.

In December 2001, the Company entered into an agreement with Lonza to
manufacture ERBITUX at the 2,000 liter scale for use in clinical trials by Merck
KGaA (the "2,000L Lonza Agreement"). The costs associated with the agreement are
reimbursable by Merck KGaA and accordingly are accounted for as collaborative
agreement revenue and such costs are also included in research and development
expenses in the consolidated statement of operations. The Company has incurred
approximately $1,175,000 in the three months ended June 30, 2002, $3,525,000 in
the six months ended June 30, 2002, and $6,008,000 from inception through June
30, 2002 for services provided under this agreement. Approximately $2,350,000
and $133,000 were reimbursable by Merck KGaA at June 30, 2002 and December 31,
2001, respectively, and included in amounts due from corporate partners in the
consolidated balance sheets. At June 30, 2002, the estimated remaining future
commitment by the companies under this agreement is $1,175,000 in 2002.



Page 5

In January 2002, the Company executed a letter of intent with Lonza to
enter into a long-term supply agreement. The long-term supply agreement would
apply to a large scale manufacturing facility that Lonza is constructing. The
Company expects such facility would be able to produce ERBITUX in 20,000 liter
batches. The Company paid Lonza $3,250,000 for the exclusive negotiating right
of a long-term supply agreement, which amount is included in Other assets at
June 30, 2002 in the consolidated balance sheet. Such negotiations commenced
shortly thereafter and are continuing. Under certain conditions such payment
shall be refunded to the Company. Provided the Company enters into a long-term
supply agreement, such payment shall be creditable against the 20,000 liter
batch price.

(4) INVESTMENT IN VALIGEN N.V.

In May 2000, the Company made an equity investment in ValiGen N.V.
("ValiGen"), a private biotechnology company specializing in therapeutic target
identification and validation using the tools of genomics and gene expression
analysis. The Company purchased 705,882 shares of ValiGen's series A preferred
stock and received a five-year warrant to purchase 388,235 shares of ValiGen's
common stock at an exercise price of $12.50 per share. The aggregate purchase
price was $7,500,000. The Company assigned a value of $594,000 to the warrant
based on the Black-Scholes Pricing Model. The ValiGen series A preferred stock
contains voting rights identical to holders of ValiGen's common stock. Each
share of ValiGen series A preferred stock is convertible into one share of
ValiGen common stock. The Company may elect to convert the ValiGen series A
preferred stock at any time; provided, that the ValiGen preferred stock will
automatically convert into ValiGen common stock upon the closing of an initial
public offering of ValiGen's common stock with gross proceeds of not less than
$20,000,000. The Company also received certain protective rights and customary
registration rights under this arrangement. The Company recorded this original
investment in ValiGen using the cost method of accounting. During the second
quarter of 2001, the Company purchased 160,000 shares of ValiGen's series B
preferred stock for $2,000,000. The terms of the series B preferred stock are
substantially the same as the series A preferred stock. The investment in
ValiGen represented approximately 7% of ValiGen's outstanding equity at the time
of purchase. As of June 30, 2001, the Company had completely written-off its
investment in ValiGen based on the modified equity method of accounting.
Included in loss on securities and investments are write-downs of the Company's
investment in Valigen of $2,775,000 and $4,375,000 for the three and six months
ended June 30, 2001, respectively. In the spring of 2001, the Company also
entered into a no-cost Discovery Agreement with ValiGen to evaluate certain of
its technology. The Company's former President and Chief Executive Officer is a
member of ValiGen's Board of Directors.

(5) NET LOSS PER COMMON SHARE

Basic and diluted net loss per common share are computed based on the net
loss for the relevant period, divided by the weighted average number of common
shares outstanding during the period. For purposes of thee diluted loss per
share calculation, the exercise or conversion of all potential common shares is
not included since their effect would be anti-dilutive for all periods
presented. As of June 30, 2002, and 2001, the Company had approximately
16,897,000 and 18,238,000, respectively, potential common shares outstanding
which represent new shares which could be issued under convertible debt, stock
options and stock warrants.

(6) COMPREHENSIVE INCOME (LOSS)

The following table reconciles net loss to comprehensive income (loss):

(7) COLLABORATIVE AGREEMENTS

(a) MERCK KGAA



Page 6

Effective April 1990, the Company entered into a development and
commercialization agreement with Merck KGaA with respect to BEC2 and the
recombinant gp75 antigen. The agreement has been amended a number of times, most
recently in December 1997. The agreement grants Merck KGaA a license, with the
right to sublicense, to make, have made, use, sell, or have sold BEC2 and gp75
outside North America. The agreement also grants Merck KGaA a license, without
the right to sublicense, to use, sell, or have sold, but not to make BEC2 within
North America in conjunction with the Company. Pursuant to the terms of the
agreement the Company has retained the rights, (1) without the right to
sublicense, to make, have made, use, sell, or have sold BEC2 in North America in
conjunction with Merck KGaA and (2) with the right to sublicense, to make, have
made, use, sell, or have sold gp75 in North America. In return, the Company has
recognized research support payments totaling $4,700,000 and is entitled to no
further research support payments under the agreement. Merck KGaA is also
required to make payments of up to $22,500,000, of which $4,000,000 has been
recognized, through June 30, 2002, based on milestones achieved in the licensed
products' development. Merck KGaA is also responsible for worldwide costs of up
to DM17,000,000 associated with a multi-site, multinational phase III clinical
trial for BEC2 in limited disease small-cell lung carcinoma. This expense level
was reached during the fourth quarter of 2000 and all expenses incurred from
that point forward are being shared 60% by Merck KGaA and 40% by the Company.
Such cost sharing applies to all expenses beyond the DM17,000,000 threshold. The
Company has incurred approximately $33,000 in the three months ended June 30,
2002 and did not incur any expenses in the three months ended June 30, 2001. The
Company has incurred approximately $154,000 and $122,000 in reimbursable
research and development expenses associated with this agreement in the six
months ended June 30, 2002 and 2001, respectively. These amounts have been
recorded as research and development expenses and also as collaborative
agreement revenue in the consolidated statements of operations. Merck KGaA is
also required to pay royalties on the eventual sales of BEC2 outside of North
America, if any. Revenues from sales, if any, of BEC2 in North America will be
distributed in accordance with the terms of a co-promotion agreement to be
negotiated by the parties.

In December 1998, the Company entered into a development and license
agreement with Merck KGaA with respect to ERBITUX. In exchange for granting
Merck KGaA exclusive rights to market ERBITUX outside of the United States and
Canada and co-development rights in Japan, the Company received through June 30,
2002, $30,000,000 in up-front fees and early cash-based milestone payments based
on the achievement of defined milestones. In March 2001, the Company satisfied a
condition relating to obtaining certain collateral license agreements associated
with the ERBITUX development and license agreement with Merck KGaA. The
satisfaction of this condition allowed for the recognition of $24,000,000 in
previously received milestone payments and initiated revenue recognition of the
$4,000,000 up-front payment received in connection with this agreement. An
additional $30,000,000 can be received, of which $5,000,000 has been received as
of June 30, 2002, assuming the achievement of further milestones for which Merck
KGaA will receive equity in the Company. The equity underlying these milestone
payments will be priced at varying premiums to the then-market price of the
common stock depending upon the timing of the achievement of the respective
milestones. If issuing shares of common stock to Merck KGaA would result in
Merck KGaA owning greater than 19.9% of our common stock, the milestone shares
will be a non-voting preferred stock, or other non-voting stock convertible into
the Company's common stock. These convertible securities will not have voting
rights. They will be convertible at a price determined in the same manner as the
purchase price for shares of the Company's common stock if shares of common
stock were to be issued. They will not be convertible into common stock if, as a
result of the conversion, Merck KGaA would own greater than 19.9% of the
Company's common stock. This 19.9% limitation is in place through December 2002.
Merck KGaA will pay the Company a royalty on future sales of ERBITUX outside of
the United States and Canada, if any. This agreement may be terminated by Merck
KGaA in various instances, including (1) at its discretion on any date on which
a milestone is achieved (in which case no milestone payment will be made), or
(2) for a one-year period after first commercial sale of ERBITUX in Merck KGaA's
territory, upon Merck KGaA's reasonable determination that the product is
economically unfeasible (in which case Merck KGaA is entitled to a return of 50%
of the cash-based up front fees and milestone payments then paid to date, but
only out of revenues received by ImClone, if any, based upon a royalty rate
applied to the gross profit from ERBITUX sales or a percentage of ERBITUX fees
and royalties received from a sublicensee on account of the sale of ERBITUX in
the United States and Canada). In August 2001, the Company and Merck KGaA
amended this agreement to provide, among other things, that Merck KGaA may
manufacture ERBITUX for supply in its territory and may utilize a third party to
do so upon the Company's reasonable acceptance. The amendment further released
Merck KGaA from its obligations under the agreement relating to providing a
guaranty under a $30,000,000 credit facility relating to the build-out of the
Company's product launch manufacturing facility. In addition, the amendment
provides that the companies have co-exclusive rights to ERBITUX in Japan,
including the right to sublicense, and that Merck KGaA has waived its right of
first offer in the case of a proposed sublicense by the Company of ERBITUX in
the Company's territory. In consideration for the amendment, the Company agreed
to a reduction in royalties payable by Merck KGaA on sales of ERBITUX in Merck
KGaA's territory.

In conjunction with Merck KGaA, the Company has expanded the trial of
ERBITUX plus radiotherapy in squamous cell carcinoma of the head and neck into
Europe, South Africa, Israel, Australia and New Zealand. In order to support
these clinical trials, Merck KGaA has agreed to purchase from the Company
ERBITUX manufactured by the Company and also by Lonza


Page 7

under the development and manufacturing services agreement and the 2000L Lonza
Agreement for use in this and other trials and further agreed to reimburse the
Company for one-half of the outside contract service costs incurred with respect
to this Phase III clinical trial of ERBITUX for the treatment of head and neck
cancer in combination with radiation. Amounts due from Merck KGaA related to
these arrangements totaled approximately $8,372,000 and $1,503,000 at June 30,
2002 and December 31, 2001, respectively, and are included in amounts due from
corporate partners in the consolidated balance sheets. The Company recorded
collaborative agreement revenue related to these arrangements in the
consolidated statements of operations totaling approximately $7,200,000 and
$461,000 in the three months ended June 30, 2002, and 2001, respectively and
$12,222,000 and $3,590,000 in the six months ended June 30, 2002, and 2001,
respectively. Of these amounts, $6,544,000 and $10,853,000 in the three and six
months ended June 30, 2002, respectively, and $393,000 and $1,423,000 in the
three and six months ended June 30, 2001, respectively, related to reimbursable
costs associated with supplying ERBITUX to Merck KGaA for use in clinical
trials. A portion of the ERBITUX sold to Merck KGaA was produced in prior
periods and the related manufacturing costs have been expensed in prior periods
when the related raw materials were purchased and the associated direct labor
and overhead was consumed or, in the case of contract manufacturing, when such
services were performed. These costs totaled $3,713,000 and $6,214,000 for the
three and six months ended June 30, 2002, respectively. Reimbursable research
and development expenses were incurred and totaled approximately $656,000 and
$1,369,000 in the three and six months ended June 30, 2002 and $68,000 and
$2,167,000 in the three and six months ended June 30, 2001. These amounts have
been recorded as research and development expenses and also as collaborative
agreement revenue in the consolidated statements of operations.

(b) BRISTOL-MYERS SQUIBB COMPANY

On September 19, 2001, the Company entered into an acquisition agreement
(the "Acquisition Agreement") with BMS and Bristol-Myers Squibb Biologics
Company, a Delaware corporation ("BMS Biologics"), which is a wholly-owned
subsidiary of BMS, providing for the tender offer by BMS Biologics to purchase
up to 14,392,003 shares of the Company's common stock for $70.00 per share, net
to the seller in cash. In connection with the Acquisition Agreement, the Company
entered into a stockholder agreement with BMS and BMS Biologics, dated as of
September 19, 2001 (the "Stockholder Agreement"), pursuant to which all parties
agreed to various arrangements regarding the respective rights and obligations
of each party with respect to, among other things, the ownership of shares of
the Company's common stock by BMS and BMS Biologics. Concurrent with the
execution of the Acquisition Agreement and the Stockholder Agreement, the
Company entered into a development, distribution and supply agreement (the
"Commercial Agreement") with BMS and its wholly-owned subsidiary E.R. Squibb &
Sons, L.L.C. ("E.R. Squibb"), relating to ERBITUX, pursuant to which, among
other things, the Company is co-developing and co-promoting ERBITUX in the
United States and Canada, and co-developing ERBITUX (together with Merck KGaA)
in Japan.

On October 29, 2001, pursuant to the Acquisition Agreement, BMS Biologics
accepted for payment pursuant to the tender offer 14,392,003 shares of the
Company's common stock on a pro rata basis from all tendering shareholders and
those conditionally exercising stock options.

On March 5, 2002, the Company amended the Commercial Agreement with E.R.
Squibb and BMS. The amendment changed certain economics of the Commercial
Agreement and has expanded the clinical and strategic roles of BMS in the
ERBITUX development program. One of the principal economic changes to the
Commercial Agreement is that the Company received $140,000,000 on March 7, 2002
and an additional payment of $60,000,000 is payable on March 5, 2003. Such
payments are in lieu of the $300,000,000 milestone payment the Company would
have received under the original terms of the agreement upon acceptance by the
FDA of the ERBITUX rolling Biologic License Application submitted for marketing
approval to treat irinotecan-refractory colorectal cancer. In addition, the
Company agreed to resume construction of its second commercial manufacturing
facility as soon as reasonably practicable after the execution of the amendment.

In exchange for the rights granted to BMS under the amended Commercial
Agreement, the Company can receive up-front and milestone payments totaling
$900,000,000 in the aggregate, of which $200,000,000 was received on September
19, 2001, $140,000,000 was received on March 7, 2002, $60,000,000 is payable on
March 5, 2003, $250,000,000 is payable upon receipt of marketing approval from
the FDA with respect to an initial indication for ERBITUX and $250,000,000 is
payable upon receipt of marketing approval from the FDA with respect to a second
indication for ERBITUX. All such payments are non-refundable and non-creditable.
Payments received under the amended Commercial Agreement with BMS and E.R.
Squibb are being deferred and recognized as revenue based on the percentage of
actual product research and development costs incurred to date by both BMS and
the Company to the estimated total of such costs to be incurred over the term of
the agreement. Except for the Company's expenses incurred pursuant to a
co-promotion option, E.R. Squibb is also responsible for 100% of the
distribution, sales and marketing costs in the United States and Canada, and as
between the Company and E.R. Squibb, each party will be responsible for 50% of
the distribution, sales, and marketing costs and other related costs and
expenses in Japan. The Commercial Agreement provides that E.R. Squibb shall pay
the Company a 39% distribution fee on net sales of ERBITUX by


Page 8

E.R. Squibb in the United States and Canada. The Commercial Agreement also
provides that the distribution fees for the sale of ERBITUX in Japan by E.R.
Squibb or the Company shall be equal to 50% of operating profit or loss with
respect to such sales for any calendar month. In the event of an operating
profit, E.R. Squibb will pay the Company the amount of such distribution fee,
and in the event of an operating loss, the Company will credit E.R. Squibb the
amount of such distribution fee. The Commercial Agreement provides that the
Company will be responsible for the manufacture and supply of all requirements
of ERBITUX in bulk form for clinical and commercial use in the United States,
Canada and Japan and that E.R. Squibb will purchase all of its requirements of
ERBITUX in bulk form for commercial use from the Company. The Company will
supply ERBITUX for clinical use at the Company's fully burdened manufacturing
cost, and will supply ERBITUX for commercial use at the Company's fully burdened
manufacturing cost plus a mark-up of 10%. In addition to the up-front and
milestone payments, the distribution fees for the United States, Canada and
Japan and the 10% mark-up on the commercial supply of ERBITUX, E.R. Squibb is
also responsible for 100% of the cost of all clinical studies other than those
studies undertaken post-launch which are not pursuant to an Investigational New
Drug Application ("INDA") (e.g., phase IV studies), the cost of which will be
shared equally between E.R. Squibb and the Company. As between E.R. Squibb and
the Company, each will be responsible for 50% of the cost of all clinical
studies in Japan.

Unless earlier terminated pursuant to the termination rights discussed
below, the Commercial Agreement expires with regard to the Product in each
country in the Territory on the later of September 19, 2018 and the date on
which the sale of the Product ceases to be covered by a validly issued or
pending patent in such country. The Commercial Agreement may also be terminated
prior to such expiration as follows:

- by either party, in the event that the other party materially
breaches any of its material obligations under the Commercial
Agreement and has not cured such breach within 60 days after notice;

- by E.R. Squibb, if the joint executive committee (the "JEC") formed
by BMS and the Company determines that there exists a significant
concern regarding a regulatory or patient safety issue that would
seriously impact the long-term viability of all products; or

- by either party, in the event that the JEC does not approve
additional clinical studies that are required by the FDA in
connection with the submission of the initial regulatory filing with
the FDA within 90 days of receiving the formal recommendation of the
product development committee concerning such additional clinical
studies.

The Company incurred approximately $2,250,000 during the three months
ended March 31, 2002 in advisor fees associated with the amendment to the
Commercial Agreement with BMS and affiliates, which have been expensed and
included as a separate line item in operating expenses in the consolidated
statement of operations.

Amounts due from BMS related to this agreement totaled approximately
$8,157,000 and $6,714,000 at June 30, 2002 and December 31, 2001, respectively,
and are included in amounts due from corporate partners in the consolidated
balance sheets. The Company recorded collaborative agreement revenue related to
this agreement in the consolidated statements of operations totaling
approximately $2,426,000 and $8,521,000 in the three and six months ended June
30, 2002, respectively. Of these amounts, $1,960,000 and $3,810,000 in the three
and six months ended June 30, 2002, respectively, related to reimbursable costs
associated with supplying ERBITUX for use in clinical trials associated with
this agreement. The related manufacturing costs have been expensed in prior
periods when the related raw materials were purchased and the associated
manufacturing direct labor and overhead was consumed or, in the case of contract
manufacturing, when such services were performed. Reimbursable research and
development and marketing expenses were incurred and totaled approximately
$466,000 and $4,711,000 in the three and six months ended June 30, 2002. These
amounts have been recorded as research and development and marketing, general
and administrative expenses and also as collaborative agreement revenue in the
consolidated statements of operations.

In June 2002, the Company and BMS agreed that certain reimbursable ERBITUX
clinical trial costs would in fact be borne by the Company. This resulted in the
issuance of credit memos to BMS during the three months ended June 30, 2002
totaling approximately $2,949,000, which ultimately reduced collaborative
agreement revenue and license fee revenue in the three and six months ended June
30, 2002.

License fees and milestone revenues consist of the following:

(8) CONTINGENCIES

The Company and certain of its officers and directors are named as
defendants in a number of complaints filed beginning in January 2002 on behalf
of purported classes of its stockholders asserting claims under Section 10(b) of
the Securities and Exchange Act of 1934 (the "Exchange Act"), Rule 10b-5
promulgated thereunder and Section 20(a) of the Exchange Act. By order dated
June 4, 2002 these actions were consolidated under the caption of the
first-filed of these actions, Irvine v. Imclone Systems Incorporated et at., No.
02 Civ. 0109(RO). The original complaints in these actions allege generally that
various public statements made by the Company or its senior officers during 2001
and early 2002 regarding the prospects for FDA approval of ERBITUX were false or
misleading when made, that various Company insiders were aware of material,
non-public information regarding the actual prospects for ERBITUX at the time
that those insiders engaged in transactions in the Company's common stock and
that members of the purported shareholder class suffered damages when the market
price of the Company's common stock declined following disclosure of the
information that allegedly had not been previously disclosed. On December 28,
2001, the Company disclosed that it had received a "refusal to file" letter from
the FDA relating to its biologics license application for ERBITUX. Thereafter,
various news articles purported to describe the contents of the FDA's "refusal
to file" letter. During this period, the market price of the Company's common
stock declined. The complaints in the various actions seek to proceed on behalf
of a class of the Company's present and former stockholders, other than
defendants or persons affiliated with the defendants, seek monetary damages in
an unspecified amount and seek recovery of plaintiffs' costs and attorneys'
fees. A consolidated amended complaint is expected to be filed shortly.

Beginning on January 13, 2002 and continuing thereafter, eight separate
purported stockholders derivative actions have been filed against the members of
its board of directors and the Company, as nominal defendant, making allegations
similar to the allegations in the federal securities class action complaints.
All of these actions assert claims, purportedly on the Company's behalf, for
breach of fiduciary duty by certain members of the board of directors based on
the allegation that certain directors engaged in transactions in the Company's
common stock while in possession of material, non-public information concerning
the regulatory and marketing prospects for ERBITUX. Another complaint,
purportedly asserting direct claims on behalf of a class of the Company's
shareholders but in fact asserting derivative claims that are similar to those
asserted in these eight cases, was filed in the U.S. District Court for the
Southern District of New York on February 13, 2002, styled Dunlap v. Waksal, et
al., No. 02 Civ. 1154 (RO). The Dunlap complaint asserts claims against the
board of directors for breach of fiduciary duty purportedly on behalf of all
persons who purchased shares of the Company's common stock prior to June 28,
2001 and then held those shares through December 6, 2001. It alleges that the
members of the purported class suffered damages as a result of holding their
shares based on allegedly false information about the financial prospects of the
Company that was disseminated during this period.

All of these actions are in their earliest stages and a reserve has not
been established in the accompanying consolidated financial statements because
the Company does not believe at this time that a loss is probable or estimable.
The Company intends to contest vigorously the claims asserted in these actions.

The Company has received subpoenas and requests for information in
connection with investigations by the Securities and Exchange Commission, the
Subcommittee on Oversight and Investigations of the U.S. House of
Representatives Committee on Energy and Commerce and the U.S. Department of
Justice relating to the circumstances surrounding the disclosure of the FDA
letter dated December 28, 2001 and trading in the Company's securities by
certain Company insiders in 2001. The Company is cooperating with all of these
inquiries and intends to continue to do so.

On June 19, 2002, the Company received a written "Wells Notice" from the
staff of the Securities and Exchange Commission, indicating that the staff is
considering recommending the Commission bring an action against the Company
relating to the Company's disclosure immediately following its receipt of a
Refusal-to-File letter from the FDA on December 28, 2001 for its biologics
license application for ERBITUX. The Company filed a Wells submission on July
12, 2002 in response to the staff's Wells Notice. The Company has also received
permission from the Commission to file a supplemental Wells submission, and the
Company anticipates that it will make this submission in September of this year.

The Company has incurred legal fees associated with these matters totaling
approximately $5,724,000 during the six months ended June 30, 2002. In addition,
the Company has estimated and recorded a receivable totaling $2,350,000 for a
portion of the above mentioned legal fees that the Company believes are
recoverable from its insurance carriers. This receivable is included in Other
current assets in the consolidated balance sheet at June 30, 2002.

(9) CERTAIN RELATED PARTY TRANSACTIONS

In September 2001 and February 2002, the Company entered into employment
agreements with six senior executive officers, including the then President and
Chief Executive Officer and the then Chief Operating Officer. The then President
and Chief Executive Officer resigned in May 2002 and the then Chief Operating
Officer was appointed to President and Chief Executive Officer. The September
agreements each have three-year terms and the February agreement has a one-year
term. The February 2002 agreement was amended in April 2002. The term of
employment for the present CEO will be automatically extended for one additional
day each day during the term of employment unless either the Company or the
Executive otherwise gives notice. The employment agreements provide for stated
base salaries, and minimum bonuses and benefits aggregating $3,765,000 annually.

Page 11

Certain transactions engaged in by the Company's former President and
Chief Executive Officer, Dr. Samuel Waksal, in securities of the Company were
deemed to have resulted in "short-swing profits" under Section 16 of the
Securities Exchange Act of 1934 (the "Exchange Act"). In accordance with Section
16(b) of the Exchange Act, Dr. Waksal has paid the Company an aggregate amount
of approximately $486,000, in March 2002, and an additional amount of
approximately $79,000 in July 2002, as disgorgement of "short-swing profits" he
was deemed to have realized. The amount received in March 2002 was recorded as
an increase to additional paid-in capital.

(10) STOCKHOLDER RIGHTS PLAN

On February 15, 2002, the Company's Board of Directors approved a
Stockholder Rights Plan and declared a dividend of one right for each share of
its common stock outstanding at the close of business on February 19, 2002. In
connection with the Board of Directors' approval of the Stockholders Rights
Plan, Series B Participating Cumulative Preferred Stock was created. Under
certain conditions, each right entitles the holder to purchase from the Company
one-hundredth of a share of series B Participating Cumulative Preferred Stock at
an initial purchase price of $175 per share. The Stockholder Rights Plan is
designed to enhance the Board's ability to protect stockholders against, among
other things, unsolicited attempts to acquire control of the Company that do not
offer an adequate price to all of the Company's stockholders or are otherwise
not in the best interests of the Company and its stockholders.

Subject to certain exceptions, rights become exercisable (i) on the tenth
day after public announcement that any person, entity, or group of persons or
entities has acquired ownership of 15% or more of the Company's outstanding
common stock, or (ii) 10 business days following the commencement of a tender
offer or exchange offer by any person that would, if consummated, result in such
person acquiring ownership of 15% or more of the Company's outstanding common
stock, (collectively an "Acquiring Person").

In such event, each right holder will have the right to receive the number
of shares of common stock having a then current market value equal to two times
the aggregate exercise price of such rights. If the Company were to enter into
certain business combination or disposition transactions with an Acquiring
Person, each right holder will have the right to receive shares of common stock
of the acquiring company having a value equal to two times the aggregate
exercise price of the rights.

The Company may redeem these rights in whole at a price of $.001 per
right. The rights expire on February 15, 2012.

(11) SEPARATION AGREEMENT

On May 22, 2002, the Company accepted the resignation of its President and
Chief Executive Officer, Dr. Samuel D. Waksal. In connection with the
resignation, on May 24, 2002 the Company and Dr. Waksal executed a separation
agreement whereby Dr. Waksal received a lump sum payment totaling $7,000,000 and
is entitled to receive for defined periods of time the continuation of certain
benefits including health care and life insurance coverage with an estimated
cost of $283,000. The related expense of $7,283,000 is included in Marketing,
general and administrative expenses in the consolidated statement of operations
for the three and six months ended June 30, 2002. In addition, 1,250,000 stock
option awards granted to Dr. Waksal on September 19, 2001 which were exercisable
at a per share exercise price of $50.01 and constituted all outstanding stock
option awards held by Dr. Waksal, were deemed amended such that the unvested
portion vested immediately as of the date of termination. The amended stock
option awards can be exercised at any time until the end of the term of such
awards. No compensation expense was recorded because the fair market value of
the Company's common stock was below the $50.01 exercise price on the date the
option award was amended. On August 7, 2002, a federal grand jury indicted Dr.
Samuel D. Waksal. The Company has recently learned that Dr. Waksal, in
contravention of Company policy, directed the destruction of certain documents
that were, or could be perceived to be, material to the pending government
investigations. Accordingly, on August 14, 2002, the Company filed an action
against Dr. Waksal in New York State Supreme Court seeking repayment of amounts
paid to him by the Company pursuant to the separation agreement, cancellation or
recovery of other benefits provided under that agreement (including cancellation
of all stock options that vested as a result of the agreement), disgorgement of
amounts previously advanced by the Company on behalf of Dr. Waksal for his legal
fees and expenses, and repayment of certain amounts paid under Dr. Waksal's
previous employment agreement. The action is in its earliest stages.

(12) 2002 STOCK OPTION PLAN

In June 2002, the shareholders approved and the Company adopted the 2002
Stock Option Plan. The plan provides for the granting of both incentive stock
options and non-qualified stock options to purchase 3,300,000 shares of the
Company's common stock to employees, directors, consultants and advisors of the
Company. Options granted under the plan generally vest over one to five year
periods and unless earlier terminated, expire ten years from the date of grant.
Incentive stock options granted under the 2002 stock option plan may not exceed
825,000 shares of common stock, may not be granted at a price less than the fair
market value of the stock at the date of grant and may not be granted to
non-employees.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

The following discussion and analysis by our management is provided to
identify certain significant factors that affected our financial position and
operating results during the periods included in the accompanying financial
statements.

CRITICAL ACCOUNTING POLICIES

During January 2002, the Securities and Exchange Commission ("SEC")
published a Commission Statement in the form of Financial Reporting Release No.
61, which requested that all registrants discuss their most "critical accounting
policies" in management's discussion and analysis of financial condition and
results of operations. The SEC has defined critical accounting policies as those
that are both important to the portrayal of a company's financial condition and
results, and that require management's most difficult, subjective or complex
judgments, often as a result of the need to make estimates about the effect of
matters that are inherently uncertain. While our significant accounting policies
are summarized in Note 2 to our consolidated financial statements included in
Form 10-K for the fiscal year ended December 31, 2001, we believe the following
accounting policies to be critical:

Revenue - We adopted Staff Accounting Bulletin No. 101 ("SAB 101") in the
fourth quarter of 2000 with an effective date of January 1, 2000, implementing a
change in accounting policy with respect to revenue recognition. Beginning
January 1, 2000, non-refundable fees received upon entering into collaborative
agreements in which the Company has continuing involvement are recorded as
deferred revenue and recognized over the estimated service period. See Note 7.

Payments received under the development, promotion, distribution and
supply agreement (the "Commercial Agreement") dated September 19, 2001 and as
amended on March 5, 2002 with Bristol-Myers Squibb Company ("BMS") and E.R.
Squibb & Sons, L.L.C., a Delaware limited liability company and a wholly-owned
subsidiary of BMS ("E.R. Squibb"), relating to ERBITUX, are being deferred and
recognized as revenue based upon the actual product research and development
costs incurred to date by BMS, E.R. Squibb and ImClone Systems as a percentage
of the estimated total of such costs to be incurred over the term of the
agreement. Of the $340,000,000 in upfront payments we received from BMS through
June 30, 2002, approximately $8,066,000 was recognized as revenue during the six
months ended June 30, 2002 and $10,618,000 from the commencement of the
agreement through June 30, 2002.

The methodology used to recognize revenue deferred involves a number of
estimates and judgments, such as the estimate of total product research and
development costs to be incurred under the Commercial Agreement. Changes in
these estimates and judgments can have a significant effect on the size and
timing of revenue recognition.

Non-refundable milestone payments, which represent the achievement of a
significant step in the research and development process, pursuant to
collaborative agreements other than the Commercial Agreement with BMS, are
recognized as revenue upon the achievement of the specified milestone.

Production Costs - The costs associated with the manufacture of ERBITUX
are included in research and development expenses when incurred and will
continue to be so classified until such time as ERBITUX may be approved for sale
or until we obtain obligations from our corporate partners for supply of such
product. In the event of such approval or obligations from our corporate
partners, the subsequent costs associated with manufacturing ERBITUX for
commercial sale will be included in inventory and expensed as cost of goods sold
when sold. If ERBITUX is approved by the United States Food and Drug
Administration ("FDA"), any subsequent sale of this inventory, previously
expensed, will result in revenue from product sales with no corresponding cost
of goods sold.

Litigation - We are currently involved in certain legal proceedings as
discussed in "Contingencies" Note 8 to the financial statements. In accordance
with Statement of Financial Accounting Standards No. 5, no legal reserve has
been established in our financial statements for these matters because we do not
believe at this time that a loss is probable or estimable. However, if in a
future period, we deem it probable that an unfavorable ruling in any such legal
proceeding will occur and such amount is estimable, there exists the possibility
of a material adverse impact on the operating results of that period.

Long-Lived Assets - We review long-lived assets for impairment when events
or changes in business conditions indicate that their full carrying value may
not be recovered. Assets are considered to be impaired and written down to fair
value if expected associated undiscounted cash flows are less than carrying
amounts. Fair value is generally determined as the present value of the expected
associated cash flows. We recently built a product launch manufacturing facility
and are building a second commercial manufacturing facility and a logistics and
warehousing facility, which are summarized in Note 2 to the financial
statements. The product launch manufacturing facility is dedicated to the
clinical and commercial production of ERBITUX and the second commercial
manufacturing facility will be a multi-use production facility. ERBITUX is
currently being produced for clinical trials and potential commercialization.
The logistics and warehousing facility will be the primary storage location for
ERBITUX. We believe that ERBITUX will ultimately be approved for
commercialization. As such, we believe that the full carrying value of both the
product launch manufacturing facility and the second commercial manufacturing
facility and the logistics and warehouse facility will be recovered. Changes in
business conditions in the future could change our judgments about the carrying
value of these facilities, which could result in the recognition of material
impairment losses.



Page 13

Manufacturing Contracts - As summarized under "Manufacturing Contract
Services," Note 3 to the financial statements, we have entered into certain
development and manufacturing services agreements with Lonza Biologics plc
("Lonza") for the clinical and commercial production of ERBITUX. We have
commitments from Lonza to manufacture ERBITUX at the 5,000 liter scale through
December 2003. On June 30, 2002, the estimated remaining future commitments
under the amended commercial manufacturing services agreement with Lonza were
$38,160,000 in 2002 and $24,050,000 in 2003. If ERBITUX were not to receive
regulatory approval when anticipated, it is possible that a liability would need
to be recognized for any remaining commitments to Lonza.

Valuation of Stock Options - We apply APB Opinion No. 25 and related
interpretations in accounting for our stock options and warrants. Accordingly,
compensation expense is recorded on the date of grant of an option to an
employee or member of the Board of Directors only if the fair market value of
the underlying stock at the time of grant exceeds the exercise price. In
addition, we have granted options to certain Scientific Advisory Board members
and outside consultants, which are required to be measured at fair value and
recognized as compensation expense in our consolidated statement of operations.
Estimating the fair value of stock options and warrants involves a number of
judgments and variables that are subject to significant change. A change in the
fair value estimate could have a significant effect on the amount of
compensation expense recognized.


RESULTS OF OPERATIONS

SIX MONTHS ENDED JUNE 30, 2002 AND 2001.

REVENUES

Revenues for the six months ended June 30, 2002 and 2001 were $30,116,000
and $31,890,000, respectively, a decrease of $1,774,000, or 6% in 2002. Revenues
for the six months ended June 30, 2002 primarily included $8,066,000 in license
fee revenue and $8,521,000 in collaborative agreement revenue from our amended
ERBITUX Commercial Agreement with BMS and its wholly-owned subsidiary, E.R.
Squibb. The Collaborative Agreement revenue represents certain research and
development and marketing expenses that have been incurred by us and are
reimbursable by BMS as provided for in the amended Commercial Agreement. License
fee revenue from payments under this agreement (of which $140,000,000 was
received in 2002 and $200,000,000 was received in 2001) are being recognized as
revenue over the product research and development life of ERBITUX. An additional
$60,000,000 is payable on March 5, 2003, $250,000,000 is payable upon receipt of
marketing approval from the FDA with respect to an initial indication for
ERBITUX and $250,000,000 is payable upon receipt of marketing approval from the
FDA with respect to a second indication for ERBITUX. All such payments are
non-refundable and non-creditable. We also recognized $12,495,000 in
collaborative agreement revenue from our ERBITUX development and license
agreement with Merck KGaA. In addition, we recognized $111,000 of the $4,000,000
up-front payment received upon entering into the ERBITUX development and license
agreement with Merck KGaA. This revenue is being recognized ratably over the
anticipated life of the agreement. Revenues for the six months ended June 30,
2002 also included $688,000 in royalty revenue from our strategic corporate
alliance with Abbott Laboratories ("Abbott") in diagnostics and $81,000 in
license fee revenue and $154,000 in collaborative agreement revenue from our
strategic corporate alliance with Merck KGaA for our principal cancer vaccine
product candidate, BEC2. Revenues for the six months ended June 30, 2001
primarily included $26,000,000 in milestone revenue and $3,773,000 in
collaborative agreement revenue from our ERBITUX development and license
agreement with Merck KGaA. These milestone payments were received in prior
periods and were originally recorded as fees potentially refundable to corporate
partner because they were refundable in the event a condition relating to
obtaining certain collateral license agreements was not satisfied. This
condition was satisfied in March 2001. In addition, we recognized $111,000 of
the $4,000,000 up-front payment received upon entering into this agreement. This
revenue is being recognized ratably over the anticipated life of the agreement.
Revenues for the six months ended June 30, 2001 also included $763,000 in
royalty revenue from our strategic corporate alliance with Abbott in diagnostics
and $1,000,000 in milestone revenues and $81,000 in license fee revenues and
$122,000 of collaborative agreement revenue from our strategic corporate
alliance with Merck KGaA for BEC2.

OPERATING EXPENSES:

Total operating expenses for the six months ended June 30, 2002 and 2001
were $102,797,000 and $59,437,000, respectively, an increase of $43,360,000, or
73% in 2002. Operating expenses for the six months ended June 30, 2002 included
a $2,250,000 advisor fee associated with completing the amended Commercial
Agreement.

OPERATING EXPENSES: RESEARCH AND DEVELOPMENT

Research and development expenses for the six months ended June 30, 2002
and 2001 were $75,945,000 and $49,486,000, respectively, an increase of
$26,459,000 or 53% in 2002. Research and development expenses for the six months
ended June 30, 2002 and 2001 as a percentage of total operating expenses,
excluding the advisor fee associated with the amended Commercial Agreement in
the six months ended June 30, 2002, were 76% and 83%, respectively. Research and
development expenses include costs associated with our in-house and
collaborative research programs, product and process development expenses, costs
to manufacture our product candidates, particularly ERBITUX, prior to any
approval that we may obtain of a product candidate for commercial sale or
obligations of our corporate partners to acquire product from us, quality
assurance and quality control costs, and costs to conduct our clinical trials
and associated regulatory activities. Research and development expenses include
costs that are reimbursable by our corporate partners. The increase in research
and development expenses for the six months ended June 30, 2002 was primarily
attributable to (1) the costs associated with full scale production at our
product launch manufacturing facility, (2) costs related to the manufacturing
services agreements with Lonza, (3) expenditures in the functional areas of
product development and pilot plant manufacturing associated with ERBITUX and
our antibody-based angiogenesis inhibitor product candidate for the treatment of
cancer, IMC-2C6 and (4) increased expenditures associated with discovery
research. We expect research and development costs to increase in future periods
as we continue to manufacture ERBITUX prior to any approval of the product that
we may obtain for commercial use or until we receive committed purchase
obligations of our corporate partners. In the event of such approval or
committed purchase obligations from our corporate partners, the subsequent costs
associated with manufacturing ERBITUX for supply to E.R. Squibb for commercial
use will be included in inventory and expensed as cost of goods sold when sold.
We expect research and development costs associated with discovery research and
product development also to continue to increase in future periods.

OPERATING EXPENSES: MARKETING, GENERAL AND ADMINISTRATIVE

Marketing, general and administrative expenses include marketing and
administrative personnel costs, including related occupancy costs, additional
costs to develop internal marketing and sales capabilities, costs to pursue
arrangements with strategic corporate partners and technology licensors, and
expenses associated with applying for patent protection for our technology and
products. Marketing, general and administrative expenses include amounts
reimbursable from our corporate partners. Marketing, general and administrative
expenses for the six months ended June 30, 2002 and 2001 were $24,602,000 and
$9,951,000, respectively, an increase of $14,651,000, or 147% in 2002. The
increase in marketing, general and administrative expenses primarily reflected
(1) the separation compensation and other post-employment benefits associated
with the resignation of the Company's former President and Chief Executive
Officer (2) legal expenses associated with the pending class action lawsuits,
shareholder derivative lawsuits and investigations by the SEC, the Subcommittee
on Oversight and Investigation of the U.S. House of Representatives Committee
on Energy and Commerce and the U.S. Department of Justice, (3) costs associated
with our marketing efforts, (4) additional administrative staffing required to
support our commercialization efforts for ERBITUX and (5) expenses associated
with general corporate activities. Other than the legal expenses component
discussed in (2) above and related costs, whose level in the future is
uncertain because it depends upon the manner in which these investigations and
proceedings progress, we expect marketing, general and administrative expenses
to increase in future periods to support our continued commercialization
efforts for ERBITUX.

INTEREST INCOME, INTEREST EXPENSE AND OTHER (INCOME) EXPENSE

Interest income was $5,168,000 for the six months ended June 30, 2002
compared with $7,827,000 for the six months ended June 30, 2001, a decrease of
$2,659,000, or 34% in 2002. The decrease was primarily attributable to a
decrease in interest rates associated with our portfolio of debt securities.
Interest expense was $6,839,000 and $6,510,000 for the six months ended June 30,
2002 and 2001, respectively, an increase of $329,000 or 5% in 2002. Interest
expense for the six months ended June 30, 2002 and 2001 was offset by the
capitalization of interest costs of $780,000 and $1,120,000, respectively,
during the construction period of our product launch manufacturing facility and
a second commercial manufacturing facility for which design, engineering, and
pre-construction costs have been incurred. Interest expense for both periods
included (1) interest on the 5 -1/2% convertible subordinated notes due March 1,
2005 (the "Convertible Subordinated Notes") issued in February 2000, (2)
interest on an outstanding Industrial Development Revenue Bond issued in 1990
(the "1990 IDA Bond") with a principal amount of $2,200,000 and (3) interest
recorded on various capital lease obligations under a 1996 financing agreement
and a 1998 financing


Page 15

agreement with Finova Technology Finance, Inc. ("Finova"). We recorded gains on
securities and investments of $1,236,000 and losses of $4,467,000 for the six
months ended June 30, 2002 and 2001, respectively. The losses on securities and
investments for the six months ended June 30, 2001 included $4,375,000 in
write-downs of our investment in ValiGen N.V. and a $1,000,000 write-off of our
convertible promissory note from A.C.T. Group, Inc.

NET LOSSES

We had a net loss of $73,116,000 or $1.00 per share for the six months
ended June 30, 2002, compared with a net loss of $30,698,000 or $0.46 per share
for the six months ended June 30, 2001. The increase in the net losses and per
share net loss to common stockholders was due to the factors noted above.


THREE MONTHS ENDED JUNE 30, 2002 AND 2001.

REVENUES

Revenues for the three months ended June 30, 2002 and 2001 were
$11,565,000 and $3,895,000, respectively, an increase of $7,670,000, or 197% in
2002. Revenues for the three months ended June 30, 2002 primarily included
$1,499,000 in license fee revenue and $2,426,000 in collaborative agreement
revenue from our amended Commercial Agreement with BMS and its wholly-owned
subsidiary, E.R. Squibb. The Collaborative Agreement revenue represents certain
research and development and marketing expenses that have been incurred by us
and are reimbursable by BMS as provided for in the amended Commercial Agreement.
License fee revenue from payments under this agreement (of which $140,000,000
was received in 2002 and $200,000,000 was received in 2001) are being recognized
over the product research and development life of ERBITUX. We also recognized
$7,473,000 in collaborative agreement revenue from our ERBITUX development and
license agreement with Merck KGaA. In addition, we recognized $55,000 of the
$4,000,000 up-front payment received upon entering into the ERBITUX development
and license agreement with Merck KGaA. This revenue is being recognized ratably
over the anticipated life of the agreement. Revenues for the three months ended
June 30, 2002 also included $38,000 in royalty revenue from our strategic
corporate alliance with Abbott in diagnostics and $41,000 in license fee revenue
and $33,000 in collaborative agreement revenue from our strategic corporate
alliance with Merck KGaA for BEC2. Revenues for the three months ended June 30,
2001 primarily included $2,000,000 in milestone revenue and $644,000 in
collaborative agreement revenue from our ERBITUX development and license
agreement with Merck KGaA. These milestone payments were received in prior
periods and were originally recorded as fees potentially refundable to corporate
partner because they were refundable in the event a condition relating to
obtaining certain collateral license agreements was not satisfied. This
condition was satisfied in March 2001. In addition, we recognized $55,000 of the
$4,000,000 up-front payment received upon entering into this agreement. This
revenue is being recognized ratably over the anticipated life of the agreement.
Revenues for the three months ended June 30, 2001 also included $115,000 in
royalty revenue from our strategic corporate alliance with Abbott in diagnostics
and $1,000,000 in milestone revenues and $41,000 in license fee revenues from
our strategic corporate alliance with Merck KGaA for BEC2.

OPERATING EXPENSES:

Total operating expenses for the three months ended June 30, 2002 and 2001
were $54,646,000 and $30,613,000, respectively, an increase of $24,033,000, or
79% in 2002.

OPERATING EXPENSES: RESEARCH AND DEVELOPMENT

Research and development expenses for the three months ended June 30, 2002
and 2001 were $38,167,000 and $24,390,000, respectively, an increase of
$13,777,000 or 56% in 2002. Such amounts for the three months ended June 30,
2002 and 2001 represented 70% and 80%, respectively, of total operating
expenses. Research and development expenses include costs associated with our
in-house and collaborative research programs, product and process development
expenses, costs to manufacture our product candidates, particularly ERBITUX,
prior to any approval that we may obtain of a product candidate for commercial
sale or obligations of our corporate partners to acquire product from us,
quality assurance and quality control costs, and costs to conduct our clinical
trials and associated regulatory activities. Research and development expenses
include costs that are reimbursable by our corporate partners. The increase in
research and development expenses for the three months ended June 30, 2002 was
primarily attributable to (1) the costs associated with full scale production at
our product launch manufacturing facility, (2) costs related to the
manufacturing services agreements with Lonza, (3) expenditures in the functional
areas of product development and pilot plant manufacturing associated with
ERBITUX and IMC-2C6 and (4) increased expenditures associated with discovery
research. We expect research and development costs to increase in future periods
as we continue to manufacture


Page 16

ERBITUX prior to any approval of the product that we may obtain for commercial
use or until we receive committed purchase obligations of our corporate
partners. In the event of such approval or committed purchase obligations from
our corporate partners, the subsequent costs associated with manufacturing
ERBITUX for supply to E.R. Squibb for commercial use will be included in
inventory and expensed as cost of goods sold when sold. We expect research and
development costs associated with discovery research and product development
also to continue to increase in future periods.

OPERATING EXPENSES: MARKETING, GENERAL AND ADMINISTRATIVE

Marketing, general and administrative expenses include marketing and
administrative personnel costs, including related occupancy costs, additional
costs to develop internal marketing and sales capabilities, costs to pursue
arrangements with strategic corporate partners and technology licensors, and
expenses associated with applying for patent protection for our technology and
products. Marketing, general and administrative expenses include amounts
reimbursable from our corporate partner. Marketing, general and administrative
expenses for the three months ended June 30, 2002 and 2001 were $16,479,000 and
$6,223,000, respectively, an increase of $10,256,000, or 165% in 2002. The
increase in marketing, general and administrative expenses primarily reflected
(1) the separation compensation and other post-employment benefits associated
with the resignation of the Company's former President and Chief Executive
Officer (2) legal expenses associated with the pending class action lawsuits,
shareholder derivative lawsuits and investigations by the SEC, the Subcommittee
on Oversight and Investigation of the U.S. House of Representatives Committee
on Energy and Commerce and the U.S. Department of Justice, (3) costs associated
with our marketing efforts, (4) additional administrative staffing required to
support our commercialization efforts for ERBITUX and (5) expenses associated
with general corporate activities. Other than the legal expenses component
discussed in (2) above and related costs, whose level in the future is
uncertain because it depends upon the in which these investigations and
proceedings progress, we expect marketing, general and administrative expenses
to increase in future periods to support our continued commercialization
efforts for ERBITUX.

INTEREST INCOME, INTEREST EXPENSE AND OTHER (INCOME) EXPENSE

Interest income was $2,904,000 for the three months ended June 30, 2002
compared with $3,262,000 for the three months ended June 30, 2001, a decrease of
$358,000, or 11% in 2002. The decrease was primarily attributable to a decrease
in interest rates associated with our portfolio of debt securities. Interest
expense was $3,347,000 and $3,197,000 for the three months ended June 30, 2002
and 2001, respectively, an increase of $150,000 or 5% in 2002. Interest expense
for the three months ended June 30, 2002 and 2001 was offset by the
capitalization of interest costs of $481,000 and $626,000, respectively, during
the construction period of our product launch manufacturing facility and a
second commercial manufacturing facility for which design, engineering, and
pre-construction costs have been incurred. Interest expense for both periods
included (1) interest on the Convertible Subordinated Notes issued in February
2000, (2) interest on an outstanding 1990 IDA Bond with a principal amount of
$2,200,000 and (3) interest recorded on various capital lease obligations under
a 1996 financing agreement and a 1998 financing agreement with Finova. We
recorded gains on securities and investments of $435,000 and losses of
$2,850,000 for the three months ended June 30, 2002 and 2001, respectively. The
losses on securities and investments for the three months ended June 30, 2001
included a $2,775,000 write-down of our investment in ValiGen N.V and a
$1,000,000 write-off of our convertible promissory note from A.C.T. Group, Inc.

NET LOSSES

We had a net loss of $43,089,000 or $0.59 per share for the three months
ended June 30, 2002, compared with a net loss of $29,503,000 or $0.44 per share
for the three months ended June 30, 2001. The increase in the net losses and per
share net loss to common stockholders was due to the factors noted above.

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 2002, our principal sources of liquidity consisted of cash and
cash equivalents and securities available for sale of approximately
$352,000,000. From our inception on April 26, 1984 through June 30, 2002, we
have financed our operations primarily through the following means:

- Public and private sales of equity securities and convertible notes
in financing transactions have raised approximately $492,652,000 in
net proceeds

- We have earned approximately $109,531,000 from license fees,
contract research and development fees, reimbursements from our
corporate partners and royalties from collaborative partners.
Additionally, we have


Page 17

approximately $335,239,000 in deferred revenue related to up-front
payments received from our amended Commercial Agreement for ERBITUX
with BMS, our ERBITUX development and license agreement with Merck
KGaA and our BEC2 development and commercialization agreement with
Merck KGaA. These amounts are being recognized as revenue over the
expected lives of the respective agreements

- We have earned approximately $52,282,000 in interest income

- The sale of the IDA Bonds in each of 1985, 1986 and 1990 raised an
aggregate of $6,300,000, the proceeds of which have been used for
the acquisition, construction and installation of our research and
development facility in New York City, and of which $2,200,000 is
outstanding

We may, from time to time, consider a number of strategic alternatives
designed to increase shareholder value, which could include joint ventures,
acquisitions and other forms of alliances, as well as the sale of all or part of
the Company.

Until September 19, 2006, or earlier upon the occurrence of certain
specified events, we may not take any action that constitutes a prohibited
action under our stockholder agreement with BMS and Bristol-Myers Squibb
Biologics Company, a Delaware corporation ("BMS Biologics"), which is a
wholly-owned subsidiary of BMS, without the consent of the BMS directors. Such
prohibited actions include (i) issuing additional shares or securities
convertible into shares in excess of 21,473,002 shares of our common stock in
the aggregate, subject to certain exceptions; (ii) incurring additional
indebtedness if the total of the principal amount of such indebtedness incurred
since September 19, 2001 and then-outstanding, and the net proceeds from the
issuance of any redeemable preferred stock then-outstanding, would exceed the
amount of indebtedness outstanding as of September 19, 2001 by more than $500
million; (iii) acquiring any business if the aggregate consideration for such
acquisition, when taken together with the aggregate consideration for all other
acquisitions consummated during the previous twelve months, is in excess of 25%
of the aggregate value of the Company at the time we enter into the binding
agreement relating to such acquisition; (iv) disposing of all or any substantial
portion of our non-cash assets; (v) issuing capital stock with more than one

In September 2001, we entered into the ERBITUX Commercial Agreement with
BMS and E.R. Squibb, pursuant to which, among other things, together with E.R
Squibb we are (a) co-developing and co-promoting ERBITUX in the United States
and Canada, and (b) co-developing ERBITUX (together with Merck KGaA) in Japan.
The Commercial Agreement was amended on March 5, 2002 to change certain
economics of the agreement and has expanded the clinical and strategic roles of
BMS in the ERBITUX development program. Pursuant to the amended Commercial
Agreement, we can receive up-front and milestone payments totaling $900,000,000
in the aggregate, of which $200,000,000 was received upon the signing of the
agreement. The remaining $700,000,000 in payments comprises $140,000,000 paid on
March 7, 2002, $60,000,000 payable on March 5, 2003, $250,000,000 payable upon
receipt of marketing approval from the FDA with respect to an initial indication
for ERBITUX and $250,000,000 payable upon receipt of marketing approval from the
FDA with respect to a second indication for ERBITUX. All such payments are
non-refundable and non-creditable. Except for our expenses incurred pursuant to
the co-promotion option, E.R. Squibb is responsible for 100% of the
distribution, sales and marketing costs in the United States and Canada, and
E.R. Squibb and the Company, each will be responsible for 50% of the
distribution, sales, marketing costs and other related costs and expenses in
Japan. The Commercial Agreement provides that E.R. Squibb shall pay us
distribution fees based on a percentage of annual sales of ERBITUX by E.R.
Squibb in the United States and Canada. The distribution fee is 39% of net sales
in the United States and Canada. The Commercial Agreement also provides that the
distribution fees for the sale of ERBITUX in Japan by E.R. Squibb or us shall be
equal to 50% of operating profit or loss with respect to such sales for any
calendar month. In the event of an operating profit, E.R. Squibb will pay us the
amount of such distribution fee, and in the event of an operating loss, we will
credit E.R. Squibb the amount of such distribution fee. The Commercial Agreement
provides that we will be responsible for the manufacture and supply of all
requirements of ERBITUX in bulk form for clinical and commercial use in the
United States, Canada and Japan and that E.R. Squibb will purchase all of its
requirements of ERBITUX in bulk form for commercial use from us. We will supply
ERBITUX for clinical use at our fully burdened manufacturing cost, and will
supply ERBITUX for commercial use at our fully burdened manufacturing cost plus
a mark-up of 10%. In addition to the up-front and milestone payments, the
distribution fees for the United States, Canada and Japan and the 10% mark-up on
the commercial supply of ERBITUX, E.R. Squibb is also responsible for 100% of
the cost of all clinical studies other than those studies undertaken
post-launch, which are not pursuant to an Investigational New Drug Application
("INDA") (e.g., phase IV studies), the cost of which will be shared equally
between E.R. Squibb and ImClone Systems. As between E.R. Squibb and the Company,
each will be responsible for 50% of the cost of all clinical studies in Japan.

In February 2000, we completed a private placement of $240,000,000 in 5
- -1/2% convertible subordinated notes due March 1, 2005. We received net proceeds
of approximately $231,500,000, after deducting expenses associated with the
offering.


Page 18

Accrued interest on the notes was approximately $4,400,000 at June 30, 2002. A
holder may convert all or a portion of a note into common stock at any time on
or before March 1, 2005 at a conversion price of $55.09 per share, subject to
adjustment under certain circumstances. We may redeem some or all of the notes
prior to March 6, 2003 if specified common stock price thresholds are met. On or
after March 6, 2003, we may redeem some or all of the notes at specified
redemption prices.

In December 1999, we entered into a development and manufacturing services
agreement with Lonza. This agreement was amended in April 2001 to include
additional services. Under the agreement, Lonza is responsible for process
development and scale-up to manufacture ERBITUX in bulk form under cGMP
conditions. These steps were taken to assure that the manufacturing process
would produce bulk material that conforms with our reference material and to
support in part, our regulatory filing with the FDA. As of June 30, 2002, Lonza
has completed its responsibilities under the development and manufacturing
service agreement. We had incurred approximately $7,068,000 for services
provided under this agreement through June 30, 2002. In September 2000, we
entered into a three-year commercial manufacturing services agreement with Lonza
relating to ERBITUX. This agreement was amended in June 2001 and again in
September 2001 to include additional services. As of June 30, 2002, we had
incurred approximately $24,840,000 for services provided under the commercial
manufacturing services agreement. Under these two agreements, Lonza is
manufacturing ERBITUX at the 5,000 liter scale under cGMP conditions and is
delivering it to us over a term ending no later than December 2003. The costs
associated with both of these agreements are included in research and
development expenses when incurred and will continue to be so classified until
such time as ERBITUX may be approved for sale or until we obtain obligations
from our corporate partners for supply of such product. In the event of such
approval or obligations from our corporate partners, the subsequent costs
associated with manufacturing ERBITUX for commercial sale will be included in
inventory and expensed as cost of goods sold when sold. In the event we
terminate (i.e., the cancellation of batches of bulk product) the commercial
manufacturing services agreement without cause, we will be required to pay 85%
of the stated costs for each of the first ten batches cancelled, 65% of the
stated costs for each of the next ten batches cancelled and 40% of the stated
costs for each of the next six batches cancelled. The batch cancellation
provisions for certain additional batches that we are committed to purchase
require us to pay 100% of the stated costs of cancelled batches scheduled within
six months of the cancellation, 85% of the stated costs of cancelled batches
scheduled between six and twelve months following the cancellation and 65% of
the stated costs of cancelled batches scheduled between twelve and eighteen
months following the cancellation. These amounts are subject to mitigation
should Lonza use its manufacturing capacity caused by such termination for
another customer. At June 30, 2002, the estimated remaining future commitments
under the amended commercial manufacturing services agreement are $38,160,000 in
2002 and $24,050,000 in 2003.

In December 2001, we entered into an agreement with Lonza to manufacture
ERBITUX at the 2,000 liter scale for use in clinical trials by Merck KGaA. We
had incurred approximately $6,008,000 for services provided under this
agreement, of which $3,658,000 was reimbursed by Merck KGaA. The remaining
$2,350,000 that is due from Merck KGaA is included in Amounts due from corporate
partners in the consolidated balance sheet at June 30, 2002. At June 30, 2002,
the estimated remaining future commitments under this agreement is $1,175,000 in
2002.

On January 2, 2002 we executed a letter of intent with Lonza to enter into
a long-term supply agreement. The long-term supply agreement would apply to a
large scale manufacturing facility that Lonza is constructing. We expect such
facility would be able to produce ERBITUX in 20,000 liter batches. We paid Lonza
$3,250,000 for the exclusive rights to reserve and negotiate a long-term supply
agreement for a portion of the new facility's overall capacity. Such
negotiations commenced shortly thereafter and are continuing. Under certain
conditions, such payment shall be refunded to us. If we enter into a long-term
supply agreement, such payment will be creditable to us against the 20,000 liter
batch price, such credit to be spread evenly over the batches manufactured each
year of the initial term of the long-term supply agreement.

We cannot be certain that we will be able to enter into agreements for
commercial supply with third party manufacturers on terms acceptable to us. Even
if we are able to enter into such agreements, we cannot be certain that we will
be able to produce or obtain sufficient quantities for commercial sale of our
products. Any delays in producing or obtaining commercial quantities of our
products could have a material adverse effect on our business, financial
condition and results of operations.

Effective April 1990, we entered into a development and commercialization
agreement with Merck KGaA with respect to BEC2 and the recombinant gp75 antigen.
The agreement has been amended a number of times, most recently in December
1997. The agreement grants Merck KGaA a license, with the right to sublicense,
to make, have made, use, sell, or have sold BEC2 and gp75 outside North America.
The agreement also grants Merck KGaA a license, without the right to sublicense,
to use, sell, or have sold, but not to make BEC2 within North America in
conjunction with ImClone Systems. Pursuant to the terms of the agreement we have
retained the rights, (1) without the right to sublicense, to make, have made,
use, sell, or have sold BEC2 in North America in conjunction with Merck KGaA and
(2) with the right to sublicense, to make, have made, use, sell, or have sold


Page 19

gp75 in North America. In return, we have recognized research support payments
totaling $4,700,000 and are entitled to no further research support payments
under the agreement. Merck KGaA is also required to make payments of up to
$22,500,000, of which $4,000,000 has been recognized, based on milestones
achieved in the licensed products' development. Merck KGaA is also responsible
for worldwide costs of up to DM17,000,000 associated with a multi-site,
multinational phase III clinical trial for BEC2 in limited disease small-cell
lung carcinoma. This expense level was reached during the fourth quarter of 2000
and all expenses incurred from that point forward are being shared 60% by Merck
KGaA and 40% by ImClone Systems. Such cost sharing applies to all expenses
beyond the DM17,000,000 threshold. Merck KGaA is also required to pay royalties
on the eventual sales of BEC2 outside of North America, if any. Revenues from
sales, if any, of BEC2 in North America will be distributed in accordance with
the terms of a co-promotion agreement to be negotiated by the parties.

In December 1998, we entered into a development and license agreement with
Merck KGaA with respect to ERBITUX. In exchange for granting Merck KGaA
exclusive rights to market ERBITUX outside of the United States and Canada and
co-development rights in Japan, we received through June 30, 2002, $30,000,000
in up-front fees and early cash-based milestone payments based on the
achievement of defined milestones. An additional $30,000,000 can be received, of
which $5,000,000 has been received as of June 30, 2002, assuming the achievement
of further milestones for which Merck KGaA will receive equity in ImClone
Systems. The equity underlying these milestone payments will be priced at
varying premiums to the then-market price of the common stock depending upon the
timing of the achievement of the respective milestones. If issuing shares of
common stock to Merck KGaA would result in Merck KGaA owning greater than 19.9%
of our common stock, the milestone shares will be a non-voting preferred stock,
or other non-voting stock convertible into our common stock. These convertible
securities will not have voting rights. They will be convertible at a price
determined in the same manner as the purchase price for shares of our common
stock if shares of common stock were to be issued. They will not be convertible
into common stock if, as a result of the conversion, Merck KGaA would own
greater than 19.9% of our common stock. This 19.9% limitation is in place
through December 2002. Merck KGaA will pay us a royalty on future sales of
ERBITUX outside of the United States and Canada, if any. This agreement may be
terminated by Merck KGaA in various instances, including (1) at its discretion
on any date on which a milestone is achieved (in which case no milestone payment
will be made), or (2) for a one-year period after first commercial sale of
ERBITUX in Merck KGaA's territory, upon Merck KGaA's reasonable determination
that the product is economically unfeasible (in which case Merck KGaA is
entitled to a return of 50% of the cash-based up front fees and milestone
payments then paid to date, but only out of revenues received, if any, based
upon a royalty rate applied to the gross profit from ERBITUX sales or a
percentage of ERBITUX fees and royalties from a sublicensee on account of the
sale of ERBITUX in the United States and Canada). In August 2001, ImClone
Systems and Merck KGaA amended this agreement to provide, among other things,
that Merck KGaA may manufacture ERBITUX for supply in its territory and may
utilize a third party to do so upon ImClone Systems' reasonable acceptance. The
amendment further released Merck KGaA from its obligations under the agreement
relating to providing a guaranty under a $30,000,000 credit facility relating to
the build-out of the product launch manufacturing facility. In addition, the
amendment provides that the companies have co-exclusive rights to ERBITUX in
Japan, including the right to sublicense and Merck KGaA waived its right of
first offer in the case of a proposed sublicense by ImClone Systems of ERBITUX
in ImClone Systems' territory. In consideration for the amendment, we agreed to
a reduction in royalties payable by Merck KGaA on sales of ERBITUX in Merck
KGaA's territory.

We have obligations under various capital leases for certain laboratory,
office and computer equipment and also certain building improvements, primarily
under a 1998 financing agreement with Finova. This agreement allowed us to
finance the lease of equipment and make certain building and leasehold
improvements to existing facilities. Each lease has a fair market value purchase
option at the expiration of its 48-month term. We have entered into six
individual leases under the financing agreement with an aggregate cost of
$1,942,000. This financing arrangement is now expired.

We rent our current New York corporate headquarters and research facility
under an operating lease that expires in December 2004. In 2000 we completed
renovations of the facility to better suit our needs, at a cost of approximately
$2,800,000.

In October 2001, we entered into a sublease for a four-story building in
downtown New York to serve as our future corporate headquarters and research
facility. The space, to be designed and improved in the future, includes between
75,000 and 100,000 square feet of usable space, depending on design, and
includes possible additional expansion space. The sublease has a term of 22
years, followed by two five-year renewal option periods. The future minimum
lease payments are approximately $50,625,000 over the term of the sublease. In
order to induce the sublandlord to enter into the sublease, we made a loan to
and accepted from the sublandlord a $10,000,000 note receivable. The note is
secured by a leasehold mortgage on the prime lease as well as a collateral
assignment of rents by the sublandlord. The note receivable is payable by the
sublandlord over 20 years and bears interest at 5 -1/2% in years one through
five, 6 -1/2% in years six through ten, 7 -1/2% in years eleven through fifteen
and 8 -1/2% in years sixteen through twenty. In addition, we paid the owner a
consent fee in the amount of $500,000.

On May 1, 2001, we entered into a lease for an approximately 4,000 square
foot portion of a 15,000 square foot building known as 710 Parkside Avenue,
Brooklyn, New York and we have leased an adjacent 6,250 square foot building
known as 313-315 Clarkson Avenue, Brooklyn, New York, (collectively "the
premises") to serve as our new chemistry and high throughput screening facility.
The term of the lease is for five years with five successive one-year
extensions. As of June 30, 2002, we have incurred approximately $3,778,000,
excluding capitalized interest of approximately $83,000 for the retrofit of this
facility to better fit our needs. The total cost for the retrofit will be
approximately $4,300,000.

We built a new 80,000 square foot product launch manufacturing facility
adjacent to the pilot facility in Somerville, New Jersey. The product launch
manufacturing facility was built on a 5.7 acre parcel of land we purchased in
December 1999 for approximately $700,000. The product launch manufacturing
facility contains three 10,000 liter (working volume) fermenters and is
dedicated to the clinical and commercial production of ERBITUX. The cost of the
facility was approximately $53,000,000, excluding capitalized interest of
approximately $1,966,000. The cost for the facility has come from our cash
reserves, which were primarily obtained through the issuance of debt and equity
securities. The product launch manufacturing facility was ready for its intended
use and put in operation in July 2001 and we commenced depreciation at that
time.

We have completed conceptual design and preliminary engineering plans and
are currently reviewing detailed design plans for, and proceeding with
construction of, the second commercial manufacturing facility. The second
commercial manufacturing facility will be a multi-use facility of approximately
250,000 square feet and will contain up to 10 fermenters with a total capacity
of up to 110,000 liters (working volume). The facility will be built on a 7.12
acre parcel of land that we purchased in July 2000 for approximately $950,000.
The cost of this facility, consisting of two completely fitted out suites and a
third suite with utilities only, is expected to be approximately $233,000,000,
excluding capitalized interest. The actual cost of the new facility may change
depending upon various factors. We have incurred approximately $52,617,000,
excluding capitalized interest of approximately $1,234,000, in conceptual
design, engineering, equipment and construction costs through June 30, 2002.

On January 31, 2002 we purchased a 7.5 acre parcel of land located
adjacent to the Company's product launch manufacturing facility and pilot
facility in Somerville, New Jersey. The real estate includes an existing 50,000
square foot building, 40,000 square feet of which is warehouse space and 10,000
square feet of which is office space. The purchase price for the property and
building was approximately $7,020,000, of which approximately $1,125,000 was
related to the purchase of the land and approximately $5,895,000 was related to
the purchase of the building. We intend to use this property for warehousing and
logistics for our Somerville campus.

On May 20, 2002, we purchased real estate consisting of a 6.94 acre parcel
of land located across the street from the Company's product launch
manufacturing facility in Somerville, New Jersey. The real estate includes an
existing 46,000 square feet of office space. The purchase price for the property
was approximately $4,515,000, of which approximately $1,041,000 was related to
the purchase of the land and approximately $3,474,000 was related to the
purchase of the building. We intend to use this property as the administrative
building for the Somerville campus. As of June 30, 2002, we have incurred
approximately $422,000 for the retrofit of this facility. The total cost for the
retrofit will be approximately $5,187,000.

Total capital expenditures made during the six months ended June 30, 2002
were $42,686,000 and primarily included $1,579,000 related to the purchase of
equipment for and leasehold improvement costs associated with our corporate
office and research laboratories in our New York facility, $23,437,000 related
to the conceptual design, preliminary engineering plans, capitalized interest
costs and construction costs for a second commercial manufacturing facility,
$1,125,000 and $5,895,000 for the land and building, respectively, for the
warehousing and logistics building, $1,041,000 and $3,474,000 for the land and
building, respectively, for the purchase of and $422,000 for the retrofit of the
central operations building, $3,198,000 for the retrofit of the Brooklyn
chemistry lab, $725,000 related to improving and equipping our product launch
manufacturing facility, and $1,031,000 related to improving and equipping our
pilot manufacturing facility.

We believe that our existing cash on hand, marketable securities and
amounts to which we are entitled should enable us to maintain our current and
planned operations through 2003. We are also entitled to reimbursement for
certain marketing and research and development expenditures and certain other
payments, some of which are payable upon the achievement of research and
development milestones. Such amounts include $560,000,000 in cash-based payments
of which $60,000,000 is payable on March 5, 2003, as well as up to $25,000,000
in equity-based milestone payments under our ERBITUX development and license
agreement with Merck KGaA and up to $18,500,000 in cash-based milestone payments
under our BEC2 development agreement with Merck KGaA. There can be no assurance
that we will achieve these milestones. Our future working capital and capital
requirements will depend upon numerous factors, including, but not limited to:

- progress and cost of our research and development programs,
pre-clinical testing and clinical trials



Page 21

- our corporate partners fulfilling their obligations to us

- timing and cost of seeking and obtaining regulatory approvals

- timing and cost of manufacturing scale-up and effective
commercialization activities and arrangements

- level of resources that we devote to the development of marketing
and sales capabilities

- costs involved in filing, prosecuting and enforcing patent claims

- technological advances

- legal costs and the outcome of outstanding legal proceedings and
investigations

- status of competition

- our ability to maintain existing corporate collaborations and
establish new collaborative arrangements with other companies to
provide funding to support these activities

In order to fund our capital needs after 2003, we will require significant
levels of additional capital and we intend to raise the capital through
additional arrangements with corporate partners, equity or debt financings, or
from other sources, including the proceeds of product sales, if any. There is no
assurance that we will be successful in consummating any such arrangements. If
adequate funds are not available, we may be required to significantly curtail
our planned operations.

Below is a table that presents our contractual obligations and commercial
commitments as of June 30, 2002:

New Jersey State Tax Law Changes

In July 2002, the State of New Jersey (""NJ'') enacted various income tax
law changes, which are retroactive to January 1, 2002. One of the provisions of
the new law is the suspension of the utilization of net operating losses for
2002 and 2003. This provision would negatively affect the Company if it
generates NJ taxable income in 2002 and 2003 because it would not be able to
utilize its NJ net operating loss carryover to offset such taxable income.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

On August 17, 2001, Statement of Financial Accounting Standards No. 143,
"Accounting for Asset Retirement Obligations" was issued and will be effective
for the Company in the first quarter of the year ended December 31, 2003. The
new rule requires the fair value of a liability for an asset retirement
obligation to be recognized in the period in which it is incurred. When the
liability is initially recorded, a cost is capitalized by increasing the
carrying amount of the related long-lived asset. Over time, the liability is
accreted to its present value each period, and the capitalized cost is
depreciated over the useful life of the related asset. To settle the liability,
the obligation for its recorded amount is paid or a gain or loss upon settlement
is incurred. Management will be analyzing this requirement to determine the
effect on the Company's financial statements.

In July 2002, the FASB issued SFAS No. 146, Accounting for Restructuring
Costs. SFAS 146 applies to costs associated with an exit activity (including
restructuring) or with a disposal of long-lived assets. Those activities can
include eliminating or reducing product lines, terminating employees and
contracts, and relocating plant facilities or personnel. Under SFAS 146, a
company will record a liability for a cost associated with an exit or disposal
activity when that liability is incurred and can be measured at fair value. SFAS
146 will require a company to disclose information about its exit and disposal
activities, the related costs, and changes in those costs in the notes to the
interim and annual financial statements that include the period in which an exit
activity is initiated and in any subsequent period until the activity is
completed. SFAS 146 is effective prospectively for exit or disposal activities
initiated after December 31, 2002, with earlier adoption encouraged. Under SFAS
146, a company may not restate its previously issued financial statements and
the new Statement grandfathers the accounting for liabilities that a company had
previously recorded under Emerging Issues Task Force Issue 94-3. The Company is
currently evaluating the impact of adoption of this statement.

CERTAIN FACTORS AFFECTING FORWARD-LOOKING STATEMENTS--SAFE HARBOR STATEMENT

Those statements contained herein that do not relate to historical
information are forward-looking statements. There can be no assurance that the
future results covered by such forward-looking statements will be achieved.
Actual results may differ materially due to the risks and uncertainties inherent
in our business, including without limitation, the risks and uncertainties
associated with completing pre-clinical and clinical trials of our compounds
that demonstrate such compounds' safety and effectiveness; obtaining additional
financing to support our operations; obtaining and maintaining regulatory
approval for such compounds and complying with other governmental regulations
applicable to our business; obtaining the raw materials necessary in the
development of such compounds; consummating collaborative arrangements with
corporate partners for product development; achieving milestones under
collaborative arrangements with corporate partners; developing the capacity and
ability to manufacture, as well as market and sell our products, either directly
or with collaborative partners; developing market demand for and acceptance of
such products; competing effectively with other pharmaceutical and
biotechnological products; obtaining adequate reimbursement from third-party
payors; attracting and retaining key personnel; obtaining and protecting
proprietary rights; legal costs and the outcome of outstanding legal proceedings
and investigations; and those other factors set forth in "Risk Factors" in the
Company's most recent Registration Statement and Form 10-K.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Our holdings of financial instruments comprise a mix of U.S. dollar
denominated securities that may include U.S. corporate debt, foreign corporate
debt, U.S. government debt, foreign government/agency guaranteed debt and
commercial paper. All such instruments are classified as securities available
for sale. Generally, we do not invest in portfolio equity securities,
commodities, foreign exchange contacts or use financial derivatives for trading
purposes. Our debt security portfolio represents funds held temporarily pending
use in our business and operations. We manage these funds accordingly. We seek
reasonable assuredness of the safety of principal and market liquidity by
investing in investment grade fixed income securities while at the same time
seeking to achieve a favorable rate of return. Our market risk exposure consists
principally of exposure to changes in interest rates. Our holdings are also
exposed to the risks of changes in the credit quality of issuers. We invest in
securities that have a range of maturity dates. Typically, those with a
short-term maturity are fixed-rate, highly liquid, debt instruments and those
with longer-term maturities are highly liquid debt instruments with fixed
interest rates or with periodic interest rate adjustments. The table below
presents the principal amounts and related weighted average interest rates by
year of maturity for our investment portfolio as of June 30, 2002.

(1) These holdings consist of U.S. corporate and foreign corte floating
rate notes. Interest on the securities is adjusted monthly, quarterly or
semi-annually, depending on the instrument, using prevailing interest
rates. These holdings are highly liquid and we consider the potential for
loss of principal to be minimal.

Our 5 -1/2% convertible subordinated notes in the principal amount of
$240,000,000 due March 1, 2005 and other long-term debt have fixed interest
rates. The subordinated notes are convertible into our common stock at a
conversion price of $55.09 per share. The fair value of fixed interest rate
instruments are affected by changes in interest rates and in the case of the
convertible notes by changes in the price of our common stock. The fair value of
the 5 -1/2% convertible subordinated notes (which have a carrying value of
$240,000,000) was approximately $168,300,000 at June 28, 2002.


PART II - OTHER INFORMATION

ITEM 1 - LEGAL PROCEEDINGS

A. LITIGATION

1. FEDERAL SECURITIES CLASS ACTIONS

A number of complaints asserting claims under Section 10(b) of the
Securities Exchange Act of 1934 (the "Exchange Act"), Rule 10b-5 promulgated
thereunder and Section 20(a) of the Exchange Act were filed beginning in January
2002 in the U.S. District Court for the Southern District of New York against us
and certain of our directors and officers on behalf of purported classes of our
shareholders. By order dated June 4, 2002 these actions were consolidated under
the caption of the first-filed of these actions, Irvine v. ImClone Systems
Incorporated et at., No. 02 Civ. 0109(RO). The original complaints in these
actions allege generally that various public statements made by us or our senior
officers during 2001 and early 2002 regarding the prospects for FDA approval of
ERBITUX were false or misleading when made, that various Company insiders were
aware of material, non-public information regarding the actual prospects for
ERBITUX at the time that those insiders engaged in transactions in our common
stock and that members of the purported shareholder class suffered damages when
the market price of our common stock declined following disclosure of the
information that allegedly had not been previously disclosed. On December 28,
2001, we disclosed that we had received a "refusal to file" letter from the FDA
relating to our biologics license application for ERBITUX. Thereafter, various
news articles purported to describe the contents of the FDA's "refusal to file"
letter. During this period, the market price of our common stock declined. The
complaints in the various actions seek to proceed on behalf of a class of our
present and former shareholders, other than defendants or persons affiliated
with the defendants, seek monetary damages in an unspecified amount and seek
recovery of plaintiffs' costs and attorneys' fees. A consolidated amended
complaint is expected to be filed shortly.

2. DERIVATIVE ACTIONS

Beginning on January 13, 2002 and continuing thereafter, eight separate
purported shareholder derivative actions have been filed against the members of
our Board of Directors and the Company, as nominal defendant, advancing claims
based on allegations similar to the allegations in the federal securities class
action complaints. Three of these derivative cases were filed in the Delaware
Court of Chancery and have been consolidated in that court under the caption In
re ImClone Systems Incorporated Derivative Litigation, Cons. C.A. No. 19341-NC.
An additional case has been filed in the Delaware Court of Chancery, styled Krim
v. Waksal, et al., C.A. No. 19528-NC, which likely will be consolidated with the
other actions pending in that court. In addition, two purported derivative
actions have been filed in the U.S. District Court for the Southern District of
New York, styled Lefanto v. Waksal, et al., No. 02 Civ. 0163 (LLS), and Forbes
v. Barth, et al., No. 02 Civ. 1400 (RO), and two purported derivative actions
have been filed in New York State Supreme Court in Manhattan, styled Boghosian
v. Barth, et al., Index No. 100759/02 and Johnson v. Barth, et al., Index No.
601304/02. All of these actions assert claims, purportedly on our behalf, for
breach of fiduciary duty by certain members of the Board of Directors based on
the allegation, among others, that certain directors engaged in transactions in
our common stock while in possession of material, non-public information
concerning the regulatory and marketing prospects for ERBITUX. Another
complaint, purportedly asserting direct claims on behalf of a class of the
Company's shareholders but in fact asserting derivative claims that are similar
to those asserted in these eight cases, was filed in the U.S. District Court for
the Southern District of New York on February 13, 2002, styled Dunlap v. Waksal,
et al., No. 02 Civ. 1154 (RO). The Dunlap complaint asserts claims against the
Board of Directors for breach of fiduciary duty purportedly on behalf of all
persons who purchased shares of the Company's common stock prior to June 28,
2001 and then held those shares through December 6, 2001. It alleges that the
members of the purported class suffered damages as a result of holding their
shares based on allegedly false information about the financial prospects of the
Company that was disseminated during this period.

All of these actions are in their earliest stages. We intend to contest
vigorously the claims asserted in these actions.

B. GOVERNMENT INQUIRIES AND INVESTIGATIONS

As previously reported, we have received subpoenas and requests for
information in connection with investigations by the Securities and Exchange
Commission, the Subcommittee on Oversight and Investigations of the U.S. House
of Representatives Committee on Energy and Commerce and the U.S. Department of
Justice relating to the circumstances surrounding the disclosure of the FDA
letter dated December 28, 2001 and trading in our securities by certain Company
insiders in 2001. We are cooperating with all of these inquiries and intend to
continue to do so.

On June 19, 2002, we received a written "Wells Notice" from the staff of
the Securities and Exchange Commission, indicating that the staff is considering
recommending the Commission bring an action against us relating to our
disclosure immediately following the receipt of a Refusal-to-File letter from
the FDA on December 28, 2001 for our biologics license application for ERBITUX.
We filed a Wells submission on July 12, 2002 in response to the staff's Wells
Notice. We have also received permission from the Commission to file a
supplemental Wells submission, and we anticipate that we will make this
submission in September of this year.
