ENZON, INC. AND SUBSIDIARIES
Notes To Consolidated Condensed Financial Statements
(Unaudited)

(1) Organization and Basis of Presentation

The unaudited consolidated condensed financial statements have been
prepared from the books and records of Enzon, Inc. and its subsidiaries in
accordance with accounting principles generally accepted in the United States of
America for interim financial information. Accordingly, they do not include all
of the information and footnotes required for complete annual financial
statements. In the opinion of management, all adjustments (consisting only of
normal and recurring adjustments) considered necessary for a fair presentation
have been included. Certain prior year balances were reclassified to conform to
the 2002 presentation. Interim results are not necessarily indicative of the
results that may be expected for the year.

(2) Comprehensive Income

The following table reconciles net income to comprehensive income:

Three months ended Three months ended
September 30, 2002 September 30, 2001
------------------ ------------------

Net income $12,784,000 $ 4,230,000
Other comprehensive income (loss):
Unrealized holding gain (loss)
arising during the period 2,081,000 64,000

Less: reclassification adjustment

Total other comprehensive income
(loss) 2,081,000 (821,000)
----------- -----------

Total comprehensive income $14,865,000 $ 3,409,000
=========== ===========

(3) Earnings Per Common Share

Basic earnings per share is computed by dividing the net income available
to common shareholders adjusted for cumulative undeclared preferred stock
dividends for the relevant period, by the weighted average number of shares of
Common Stock issued and outstanding during the periods. For purposes of
calculating diluted earnings per share for the three months ended September 30,
2002 and 2001, the denominator includes both the weighted average number of
shares of Common Stock outstanding and the number of dilutive Common Stock
equivalents. The number of dilutive Common Stock equivalents includes the effect
of non-qualified stock options calculated using the treasury stock method and
the number of shares issuable upon conversion of the outstanding Series A
Preferred Stock. The number of shares issuable upon conversion of the Company's
4.5% Convertible Subordinated Notes due 2008 (the "Notes") have not been
included as the effect of their inclusion would be antidilutive. As of September
30, 2002, the Company had 6,571,000 dilutive potential common shares outstanding
that could potentially dilute future earnings per share calculations.

interest were approximately $4,500,000 for the three months ended September 30,
2002. There were no cash payments for interest for the three months ended

(6) Income Taxes

The Company recognized a tax provision for the three months ended
September 30, 2002 and 2001 which represents the Company's anticipated
Alternative Minimum Tax liability based on the anticipated taxable income for
the full fiscal year.

(7) Business Segments

A single management team that reports to the Chief Executive Officer
comprehensively manages the business operations. The Company does not operate
separate lines of business or separate business entities with respect to any of
its approved products or product candidates. In addition, the Company does not
conduct any operations outside of the United States. The Company does not
prepare discrete financial statements with respect to separate product areas.
Accordingly, the Company does not have separately reportable segments as defined
by Statement of Financial Accounting Standards No. 131, "Disclosures about
Segments of an Enterprise and Related Information".

(8) Subsequent Event

In October 2002, the Company and Elan Corporation entered into an Asset
Purchase Agreement pursuant to which, and subject to the terms and conditions of
which, Enzon has agreed to acquire the United States and Canadian rights to
ABELCET(R) (Amphotericin B Lipid Complex Injection), an FDA-approved,
injectable, antifungal pharmaceutical product, along with any line extension,
new indications, new formulations and new dosage forms of ABELCET, for an
aggregate purchase price of $370 million payable in cash, subject to certain
adjustments described in the Asset Purchase Agreement. In addition, the Asset
Purchase Agreement contemplates the acquisition of the manufacturing facility
for ABELCET in Indianapolis, Indiana, marketing materials, finished inventory
and raw materials and certain contracts related to ABELCET and the manufacturing
facility. Elan will retain rights to ABELCET outside of Canada and the United
States, except to the extent Elan has any rights in Japan which will also be
conveyed to Enzon.

In connection with the transaction, Enzon expects to hire as many as 60
employees from Elan's hospital sales force who currently market and sell ABELCET
in the United States and Canada, as well as the manufacturing facility
personnel.

Upon the closing of the transactions contemplated by the Asset Purchase
Agreement, Elan and Enzon will also enter into a patent assignment agreement, a
license agreement, trademark assignment agreements, two supply agreements, and
an interim services agreement, among other documents, in order to implement the
terms of such transactions. Elan and Enzon have agreed to the assignment by Elan
to Enzon of certain patent rights and improvements specifically related to
ABELCET, as well as an exclusive license as to certain patent rights,
improvements and related intellectual property for ABELCET. The Company intends
to finance this transaction from its current cash reserves. These transactions
are expected to close in November 2002.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations

Information contained herein contains "forward-looking statements" which can be
identified by the use of forward-looking terminology such as "believes,"
"expects," "may," "will," "should," or "anticipates" or the negative thereof or
other variations thereon or comparable terminology, or by discussions of
strategy. We cannot assure you that the future results covered by the
forward-looking statements will be achieved. The matters set forth in the "Risk
Factors" section of the Company's Annual Report on Form 10-K for the fiscal year
ended June 30, 2002, which is incorporated herein by reference, constitute
cautionary statements identifying important factors with respect to such
forward-looking statements, including certain risks and uncertainties, that
could cause actual results to vary materially from the future results indicated
in such forward-looking statements. Other factors could also cause actual
results to vary materially from the future results indicated in such
forward-looking statements.

Results of Operations

Three months ended September 30, 2002 vs. Three months ended September 30, 2001

Revenues. Revenues for the three months ended September 30, 2002 increased
by 106% to $25,067,000, as compared to $12,144,000 for the three months ended
September 30, 2001. The components of revenues are net sales and royalties we
earn on the sale of our products by others and contract revenues. Net sales
increased 31% to $6,658,000 for the three months ended September 30, 2002, as
compared to $5,081,000 for the three months ended September 30, 2001. Sales of
ONCASPAR(R) increased to $2,847,000 for the three months ended September 30,
2002 from $2,158,000 in the previous year as a result of the reacquisition of
our rights to market and distribute ONCASPAR(R) for certain territories
previously licensed to Aventis. Sales of ADAGEN(R) increased by 30% for the
three months ended September 30, 2002 to $3,810,000 as compared to $2,923,000
for the three months ended September 30, 2001 due to an increase in patients.

Royalties for the three months ended September 30, 2002, increased to
$18,326,000 as compared to $6,987,000 in the prior year. The increase was
primarily due to the commencement of sales of PEG-INTRON(R) in combination with
REBETOL(R) in the U.S. PEG-INTRON received marketing approval for use in
combination with REBETOL for the treatment for chronic hepatitis C in the U.S.
in August 2001. Schering-Plough launched PEG-INTRON as combination therapy with
REBETOL in the U.S. in October 2001.

We expect ADAGEN and ONCASPAR sales to grow over the next year at similar
levels as achieved during the previous twelve months. During October 2002
Hoffmann-La Roche's PEGASYS(R), a pegylated version of its interferon product
Roferon(R)-A, was approved in the United States as a monotherapy for hepatitis
C. Based upon Schering-Plough's historical market share of the alpha interferon
market for hepatitis C, the published clinical results of PEG-INTRON and
PEGASYS, the fact that Schering-Plough received FDA approval for PEG-INTRON in
January 2001 and has been marketing the product in the United States since
February 2001 and in Europe since June 2000, and our expectation that the
overall market for the treatment of patients with hepatitis C with pegylated
alpha interferon products will increase we do not expect PEGASYS(R) to displace
PEG-INTRON as the market leader. However, we cannot assure you that the overall
market for pegylated alpha interferon products will, in fact, increase or that
Schering-Plough will be able to effectively compete with Roche in this market.
Moreover, we cannot assure you of any particular sales levels of ADAGEN,
ONCASPAR or PEG-INTRON will be achieved or maintained.

During the three months ended September 30, 2002, we had export sales and
royalties on export sales of $8,122,000, of which $7,192,000 were in Europe.
Export sales and royalties recognized on export sales for the prior year quarter
were $4,980,000, of which $4,753,000 were in Europe.

Cost of Sales. Cost of sales, as a percentage of net sales increased to
38% for the three months ended September 30, 2002 as compared to 27% for the
prior year. This increase was due to our reacquisition of ONCASPAR which
resulted in increased cost of goods sold for the product. Under the
reacquisition agreement we made a $15 million payment to Aventis in June 2002
and we will pay Aventis a 25% royalty on net sales of


8



ONCASPAR. The royalty and amortization of the $15 million payment are included
in cost of goods sold for the product, accounting for the increase in cost of
goods sold as a percentage of sales.

Research and Development. Research and development expenses increased by
16% to $4,062,000 for the three months ended September 30, 2002 from $3,497,000
for the same period last year. The increase was primarily due to the clinical
advancement and related clinical trial costs for PROTHECAN (PEG-camptothecin)
and PEG-paclitaxel and increased payroll and related expenses. Research and
development activities are expected to continue to increase significantly as we
continue the advancement of the current and additional Phase II clinical trials
for PROTHECAN, we continue our Phase I clinical trials for PEG-paclitaxel and we
conduct preclinical and clinical trials for additional compounds.

Selling, General and Administrative. Selling, general and administrative
expenses for the three months ended September 30, 2002 decreased by 4% to
$3,943,000, as compared to $4,122,000 in the same period last year. This
decrease was primarily due to charges related to the identification and review
of potential strategic acquisitions for the three months ended September 30,
2001 offset by an increase in sales and marketing costs for the three months
ended September 30, 2002, due to the reacquisition of marketing and distribution
rights for ONCASPAR.

Other Income/Expense. Interest income for the three months ended September
30, 2002 decreased to $3,453,000, as compared to $6,178,000 for the prior year.
The decrease was due to a decline in interest rates on our investments. Interest
expense, which is principally related to the $400,000,000 in 4.5% convertible
subordinated notes outstanding, remained relatively flat at $4,957,000 for the
three months ended September 30, 2002 as compared to $4,994,000 for the prior
year.

Income Taxes. During the three months ended September 30, 2002 and 2001 we
recognized a tax provision that represents our anticipated Alternative Minimum
Tax liability based on our anticipated taxable income for the full fiscal year.

Liquidity and Capital Resources

Total cash reserves, which include cash, cash equivalents and marketable
securities, were $494,033,000 as of September 30, 2002, as compared to
$485,014,000 as of June 30, 2002. The increase is primarily due to the positive
cash flow from operations. We invest our excess cash primarily in United States
government-backed securities.

As of September 30, 2002, we had $400,000,000 of 4.5% convertible
subordinated notes outstanding. The notes bear interest at an annual rate of
4.5%. Interest is payable on January 1 and July 1 of each year beginning January
2, 2002. Accrued interest on the notes was approximately $4,500,000 as of
September 30, 2002. The holders may convert all or a portion of the notes into
common stock at any time on or before July 1, 2008. The notes are convertible
into our common stock at a conversion price of $70.98 per share, subject to
adjustment in certain events. The notes are subordinated to all existing and
future senior indebtedness. On or after July 7, 2004, we may redeem any or all
of the notes at specified redemption prices, plus accrued and unpaid interest to
the day preceding the redemption date. The notes will mature on July 1, 2008
unless earlier converted, redeemed at our option or redeemed at the option of
the note-holder upon a fundamental change, as described in the indenture for the
notes. Neither we nor any of our subsidiaries are subject to any financial
covenants under the indenture. In addition, neither we nor any of our
subsidiaries are restricted under the indenture from paying dividends, incurring
debt, or issuing or repurchasing our securities.

To date, our sources of cash have been the proceeds from the sale of our
stock through public offerings and private placements, the issuance of the 4.5%
convertible subordinated notes, sales of and royalties on sales of ADAGEN,
ONCASPAR and PEG-INTRON, sales of our products for research purposes, contract
research and development fees, technology transfer and license fees and royalty
advances.

In October 2002, the Company and Elan Corporation entered into an Asset
Purchase Agreement pursuant to which, and subject to the terms and conditions of
which, Enzon has agreed to acquire the United States and Canadian rights to
ABELCET(R) (Amphotericin B Lipid Complex Injection), an FDA-approved,
injectable, antifungal pharmaceutical product, along with any line extension,
new indications, new formulations and new dosage forms of ABELCET, for an
aggregate purchase price of $370 million payable in cash, subject to certain
adjustments described in the Asset Purchase Agreement. In addition, the Asset
Purchase Agreement contemplates the acquisition of the manufacturing facility
for ABELCET in Indianapolis, Indiana, marketing materials, finished inventory
and raw materials and certain contracts related to ABELCET and the manufacturing
facility. Elan will retain rights to ABELCET outside of Canada and the United
States, except to the extent Elan has rights in Japan which will also be
conveyed to Enzon. The Company intends to finance this transaction from its
current cash reserves. This transaction is subject to certain closing conditions
and we expect it to close during November 2002.

The Company has a capital expenditure commitment for the year ending June
30, 2003 of approximately $3 million.

As of September 30, 2002, 1,043,000 shares of Series A preferred stock had
been converted into 3,325,000 shares of common stock. Accrued dividends on the
converted Series A preferred stock in the aggregate of $3,770,000 were settled
by the issuance of 235,000 shares of common stock and cash payments of
$1,947,000. The preferred shares outstanding at September 30, 2002 are
convertible into approximately 16,000 shares of common stock. Dividends accrue
on the remaining outstanding shares of Series A preferred stock at a rate of
$14,000 per year. As of September 30, 2002, there were accrued and unpaid
dividends totaling $175,500 on the 7,000 shares of Series A preferred stock
outstanding. We have the option to pay these dividends in either cash or common
stock.

Our current sources of liquidity are cash, cash equivalents, and interest
earned on such cash reserves, sales of and royalties earned on sales of ADAGEN,
ONCASPAR and PEG-INTRON, and sales of our products for research purposes and
license fees. Based upon our currently planned research and development
activities and related costs and our current sources of liquidity and taking
into account the anticipated closing of our transaction with Elan described
above, we anticipate our current cash reserves and expected cash flow from
operations will be sufficient to meet our capital, debt service and operational
requirements for the foreseeable future.

We may seek additional financing, such as through future offerings of
equity or debt securities or agreements with collaborators with respect to the
development and commercialization of products, to fund future operations and
potential acquisitions. We cannot assure you, however, that we will be able to
obtain additional funds on acceptable terms, if at all.

Critical Accounting Policies

In December 2001, the SEC 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 indicated that a
"critical accounting policy" is one which is both important to the portrayal of
the company's financial condition and results and requires 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. We
believe based on our current business that there are no critical accounting
policies, except for our accounting related to Income Taxes. Under the asset and
liability method of Statement of Financial Accounting Standards No. 109 ("SFAS
109"), deferred tax assets and liabilities are recognized for the estimated
future tax consequences attributable to differences between financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax rated
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. A valuation allowance on
net deferred tax assets is provided for when it is more likely than not that
some portion or all of the deferred tax assets will not be realized. The Company
has significant net deferred tax assets, primarily related to net operating loss
carryforwards, and continues to analyze what the level of the valuation
allowance is needed.

In August 2001, the FASB issued SFAS No. 143, Accounting for Asset Retirement
Obligations, which addresses financial accounting and reporting for obligations
associated with the retirement of tangible long-lived assets and the associated
asset retirement costs. SFAS 143 requires an enterprise to record the fair value
of an asset retirement obligation as a liability in the period in which it
incurs a legal obligation associated with the retirement of tangible long-lived
assets. Since the requirement is to recognize the obligation when incurred,
approaches that have been used in the past to accrue the asset retirement
obligation over the life of the asset are no longer acceptable. SFAS 143 also
requires the enterprise to record the contra to the initial obligation as an
increase to the carrying amount of the related long-lived asset (i.e., the
associated asset retirement costs) and to depreciate that cost over the life of
the asset. The liability is increased at the end of each period to reflect the
passage of time (i.e., accretion expense) and changes in the estimated future
cash flows underlying the initial fair value measurement. Enterprises are
required to adopt Statement 143 for fiscal years beginning after June 15, 2002.
We adopted this statement on July 1, 2002 and it had no effect on our
consolidated financial statements.

Recently Issued Accounting Standards

In October 2001, the FASB issued SFAS 144, Accounting for Impairment or
Disposal of Long-Lived Assets, which addresses financial accounting and
reporting for the impairment or disposal of long-lived assets. While SFAS 144
supersedes SFAS 121, Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be disposed of, it retains many of the fundamental
provisions of that statement. SFAS also supersedes the accounting and reporting
provisions of APB Opinion No. 30, Reporting the Results of Operations-Reporting
the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual
and Infrequently Occurring Events and Transactions, for the disposal of a
segment of a business. However, it retains the requirement in Opinion No. 30 to
report separately discontinued operations and extends that reporting to a
component of an entity that either has been disposed of (by sale, abandonment,
or in distribution to owners) or is classified as held for sale. Enterprises are
required to adopt SFAS 144 for fiscal years beginning after December 15, 2002.
This SFAS was adopted in July, 2002 and has no effect on our consolidated
financial statements.

In July 2002, FASB issued FAS No. 146, Accounting for Costs Associated
with Exit or Disposal Activities. This Standard supercedes the accounting
guidance provided by Emerging Issues Task Force Issue No. 94-3, Liability
Recognition for Certain Employee Termination Benefits and Other Costs to Exit an
Activity (including Certain Costs Incurred in a Restructuring). FAS No. 146
requires companies to recognize costs associated with exit activities when they
are incurred rather than at the date of a commitment to an exit or disposal
plan. FAS No. 146 is to be applied prospectively to exit or disposal activities
initiated after December 31, 2002. The Company is currently evaluating this
standard.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The following discussion about our exposure to market risk of financial
instruments contains forward-looking statements. Actual results may differ
materially from those described.

Our holdings of financial instruments are comprised of debt securities,
and time deposits. All such instruments are classified as securities
available-for-sale. We do not invest in portfolio equity securities or
commodities 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 rated 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 typically invest the majority of our investments in the
shorter-end of the maturity spectrum, and at September 30, 2002 all of our
holdings were in instruments maturing in four years or less.

The table below presents the principal amounts and related weighted
average interest rates by year of maturity for our investment portfolio as of
September 30, 2002.



2003 2004 2005 2006 Total Fair Value
---- ---- ---- ---- ----- ----------

Fixed Rate $ 67,585,000 $137,614,000 $ 49,070,000 $ 80,216,000 $334,485,000 $338,319,000

Average Interest Rate 2.63% 3.08% 3.94% 3.70% 3.27% --

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


Our 4.5% convertible subordinated notes in the principal amount of
$400,000,000 due July 1, 2008 have fixed interest rates. The fair value of fixed
interest rate convertible notes is affected by changes in interest rates and by
changes in the price of our common stock.

Item 4. Controls and Procedures

(a) Evaluation of disclosure controls and procedures.

Under the supervision and with the participation of our management, including
our Chief Executive Officer and Chief Financial Officer, we evaluated the
effectiveness of the design and operation of our disclosure controls and
procedures (as defined in Rule 13a-14(c) under the Exchange Act) as of a date
(the "Evaluation Date") within 90 days prior to the filing date of this report.
Based upon that evaluation, the Chief Executive Officer and Chief Financial
Officer concluded that, as of the Evaluation Date, our disclosure controls and
procedures were effective in timely alerting them to the material information
relating to us required to be included in our periodic SEC filings.

(b) Changes in internal controls.

There were no significant changes made in our internal controls during the
period covered by this report or, to our knowledge, in other factors that could
significantly affect these controls subsequent to the date of their last
evaluation.
