Item 5. Other Events

      On August 13, 2002 Enzon, Inc. announced its financial results for the
quarter and fiscal year (FY) ended June 30, 2002. Excluding the recognition of
an $8.8 million net income tax benefit, the Company's fully diluted earnings per
share for the fourth quarter of FY 2002 was $0.27. The Company's net income for
the fourth quarter of FY 2002 grew to $20.8 million or $0.47 per diluted share,
as compared to $3.3 million or $0.08 per diluted share, for the same period in
FY 2001.

      The increase in net income was principally due to increased royalties
earned on sales of PEG-INTRON(TM). Total royalties increased to $19.6 million
during the fourth quarter of FY 2002, as compared to $4.5 million for the same
period in FY 2001. In October 2001, our marketing partner, Schering-Plough
launched PEG-INTRON and REBETOL combination therapy in the U.S. for the
treatment of chronic hepatitis C. The PEG-INTRON and REBETOL treatment regimen
is the only pegylated interferon-based combination therapy approved in the
United States.

      Combined sales of the Company's other two FDA approved products,
ONCASPAR(R) and ADAGEN(R), decreased by 5 percent to $5.5 million in the fourth
quarter of FY 2002, as compared to $5.8 million for the same period in FY 2001
primarily due to the timing of ONCASPAR shipments.

      Research and development expenses for the fourth quarter of FY 2002
increased by $1.7 million or 39 percent to $5.9 million, as compared to $4.2
million for the fourth quarter of FY 2001. The increase was due primarily to
increased research and development expenditures related to the advancement of
the Company's preclinical and clinical PEG product pipeline, as well as
increased personnel and related expenditures.

      Enzon is currently conducting Phase II clinical trials for PROTHECAN(R)
(PEG-camptothecin) in three oncology indications: small cell lung, pancreatic,
and non-small cell lung cancers. Phase I clinical trials for PEG-paclitaxel and
preclinical studies for other PEG products are also ongoing. The Company expects
to initiate additional Phase II trials for PROTHECAN as both a single agent and
in combination with other oncolytics. Research and development expenses are
expected to continue to increase significantly as the Company continues the
clinical


                                       2


advancement of its PEG product pipeline and continues to strengthen its internal
development capabilities.

      Selling, general and administrative expenses for the fourth quarter of FY
2002 increased by $800 thousand or 23 percent to $4.4 million, as compared to
$3.6 million for the fourth quarter of FY 2001. This increase was primarily due
to increases in payroll and related personnel expenditures.

      During the fourth quarter of FY 2002, interest income increased to $3.9
million, as compared to $2.0 million for the fourth quarter of FY 2001 as a
result of increased interest-bearing investments. Interest expense increased to
$5.0 million for the fourth quarter of FY 2002, as compared to $275 thousand for
the comparable period in FY 2001. The increases in interest-bearing investments
and interest expense are due to the issuance of $400 million of 4.5% convertible
subordinated notes during June 2001. As of June 30, 2002 Enzon had total cash
and interest-bearing investments of $485 million.

      During the quarter ended June 30, 2002, the Company recognized a net tax
benefit of $8.8 million, primarily related to the Company's net operating losses
expected to be utilized in FY 2003.

      The Company's pre-tax and post-tax earnings per diluted share are
summarized within the following selected financial information:

ended June 30, 2001. The increase in net income for FY 2002 was primarily due to
increased royalties related to products that utilize Enzon's PEG technology.

acceptance of and continuing demand for Enzon's products and the impact of
increased competition, competitive products and pricing.
