ENZON PHARMACEUTICALS, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

(1) ORGANIZATION AND BASIS OF PRESENTATION

The unaudited condensed consolidated financial statements have been
prepared from the books and records of Enzon Pharmaceuticals, Inc. and its
subsidiaries (the "Company") in accordance with United States generally accepted
accounting principles for interim financial information and Rule 10-01 of
Regulation S-X. 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.
Interim results are not necessarily indicative of the results that may be
expected for the year. The interim consolidated financial statements should be
read in conjunction with the consolidated financial statements and the notes
thereto included in the Company's latest annual report on Form 10-K/A.

(2) MARKETABLE SECURITIES

The Company classifies its investments in debt and marketable equity
securities as available-for-sale since the Company does not have the intent to
hold them to maturity. Debt and marketable equity securities are carried at fair
market value, with the unrealized gains and losses (which are deemed to be
temporary), net of related tax effect, included in the determination of
comprehensive income and reported in stockholders' equity. The fair value of
substantially all securities is determined by quoted market prices.

The cost of the debt securities is adjusted for amortization of
premiums and accretion of discounts to maturity. The amortization, along with
realized gains and losses, is included in interest income. The cost of
securities is based on the specific identification method.

A decline in the market value of any security below cost that is deemed
to be other-than-temporary results in a reduction in carrying amount to fair
value. The impairment is charged to earnings and a new cost basis for the
security is established. Dividend and interest income are recognized when
earned.

The amortized cost, gross unrealized holding gains or losses, and fair
value for the Company's available-for-sale securities by major security type at
December 31, 2004 were as follows (in thousands):

(3) COMPREHENSIVE INCOME

Statement of Financial Accounting Standards ("SFAS") No. 130,

Company's available-for-sale securities to be included in other comprehensive
income.

(4) EARNINGS PER COMMON SHARE

Basic earnings per share is computed by dividing the net (loss) income
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 and six months ended December 31, 2003, the denominator includes both
the weighted average number of shares of Common Stock outstanding and the number
of dilutive Common Stock equivalents. As of December 31, 2004 and 2003, the
Company had 10.1 million and 9.3 million, respectively, dilutive potential
common shares outstanding that are excluded from the dilutive earnings per share
calculations as they are antidilutive.

The following table reconciles the basic and diluted earnings per share
calculations (in thousands):

(5) STOCK BASED COMPENSATION

As permitted by SFAS No. 123, "Accounting for Stock-Based
Compensation", the Company accounts for stock-based compensation arrangements in
accordance with the provisions of Accounting Principals Board ("APB") Opinion
No. 25, "Accounting for Stock Issued to Employees" and related interpretations.
Compensation expense for stock options issued to employees is based on the
difference on the date of grant between the fair value of the Company's stock
and the exercise price of the option. Stock-based compensation reflected in net
(loss) income is attributed to restricted stock. No stock-based employee
compensation cost is reflected in net (loss) income with respect to all options
granted to employees have exercise prices equal to the market value of the
underlying Common Stock at the date of grant.

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


Amortization charged to operations relating to intangible assets
totaled $4.5 million including $1.1 million which is classified in cost of sales
and manufacturing revenue for both the three months ended December 31, 2004 and
2003. For the six months ended December 31, 2004 and 2003 amortization charged
to operations relating to intangible assets totaled $9.0 million including $2.2
million which is classified in cost of sales and manufacturing revenue.
Amortization expense for these intangibles and certain other product acquisition
costs for the next five fiscal years is expected to be approximately $15.5
million per year.

(8) GOODWILL

On November 22, 2002, the Company acquired the North American rights and
operational assets associated with the development, manufacture, sales and
marketing of ABELCET(R) (Amphotericin B Lipid Complex Injection) (the "North
American ABELCET business") from Elan Corporation, plc ("Elan") for $360.0
million plus acquisition costs of approximately $9.3 million. The acquisition is
being accounted for by the purchase method of accounting in accordance with SFAS
No. 141 "Business Combinations". The amount assigned to goodwill in connection
with the ABELCET product line acquisition was recorded at $151.0 million. In
accordance with SFAS No. 142, "Goodwill and Other Intangible Assets," the
Company does not amortize goodwill but rather reviews it at least annually for
impairment. For income tax purposes, the entire amount of goodwill is deductible
and is being amortized over a 15 year period.

(9) CASH FLOW INFORMATION

The Company considers all highly liquid securities with original
maturities of three months or less to be cash equivalents. Cash payments for
interest were approximately $9.0 million for the six months ended December 31,
2004 and 2003. Income tax payments for the six months ended December 31, 2004
and 2003, respectively were $366,000 and $3.2 million.

(10) INCOME TAXES

The Company recognized a tax benefit for the six months ended December
31, 2004 at an estimated annual effective tax rate of 36%, which is based on the
projected income tax benefit and taxable loss for the fiscal year ending June
30, 2005. During the three and six months ended December 31, 2004 the Company
recorded a valuation allowance of $1.3 million and $696,000, respectively,
related to capital loss carryforwards generated during the period related to the
sale of a portion of its equity investment in NPS Pharmaceuticals, Inc. ("NPS")
and certain investments in debt and equity securities.

ENZON PHARMACEUTICALS, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

At December 31, 2004, the Company recognized approximately $68.5
million in net deferred tax assets because management concluded that it is more
likely than not that the net deferred tax assets will be realized, including the
net operating losses from operating activities and stock option exercises, based
on future operations. As of December 31, 2004, the Company carries a valuation
allowance of $17.2 million with respect to certain capital loss carryforwards,
deductible temporary differences that would result in a capital loss
carryforward when realized and federal research and development tax credits, as
the ultimate utilization of such losses and credits is not more likely than not.
The Company will continue to reassess the need for such valuation allowance
based on the future operating performance of the Company.

The tax provision for the three and six months ended December 31, 2003
was based on the Company's then projected income tax benefit and taxable loss
for the fiscal year ended June 30, 2004.

(11) 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 or contract manufacturing. In
addition, the Company does not conduct any operations outside of the United
States and Canada. The Company does not prepare discrete financial statements
with respect to separate product or contract manufacturing areas. Accordingly,
the Company does not have separately reportable segments as defined by SFAS No.
131, "Disclosures about Segments of an Enterprise and Related Information".

(12) DERIVATIVE INSTRUMENTS

In August 2003, the Company entered into a Zero Cost Protective Collar
arrangement with a financial institution to reduce the exposure associated with
the 1.5 million shares of common stock of NPS the Company received as part of a
merger termination agreement with NPS. The termination agreement imposed a limit
on the maximum number of shares that can be transferred each month. The terms of
the collar arrangement are structured so that the Company's investment in NPS
stock, when combined with the value of the collar, should secure ultimate cash
proceeds in the range of 85%-108% of the negotiated fair value per share of
$23.47 (representing a 4.85% discount off of the closing price of NPS common
stock on the day before the collar was executed). The collar is considered a
derivative cash flow hedging instrument under SFAS No. 133, "Accounting For
Derivative Instruments and Hedging Activities" and as such, the Company
periodically measures its fair value and recognizes the derivative as an asset
or a liability. The change in fair value is recorded in other comprehensive
income (See Note 3) or in the Consolidated Statement of Operations depending on
the portion of the derivative designated and effective as a hedge.

As of December 31, 2004, the market value of NPS common stock was
$18.28 per share, which is below the bottom of the collar. When the underlying
shares become unrestricted and freely tradable the Company was required to
deliver a corresponding number of underlying shares to the financial institution
as posted collateral. In order to deliver such shares, during the six months
ended December 31, 2004, the Company sold and re-purchased 375,000 shares of
common stock of NPS. The unrealized gain previously included in other
comprehensive income prior to the sale and re-purchase with respect to these
shares aggregating $1.3 million for the six months ended December 31, 2004, was
recognized in the Consolidated Statements of Operations and is included in
"Other Income". There were no sales and re-purchases of stock for the three
months ended December 31, 2004. During the three and six month periods ended
December 31, 2003, the Company sold and re-purchased 375,000 shares of common
stock of NPS. The unrealized gain previously recognized under other
comprehensive income with respect to these shares aggregating $600,000 was
recognized in the Consolidated Statements of Operations for the three and six
months ended December 31, 2003.

During November 2004, the first portion of the collar agreement matured
resulting in the Company receiving net proceeds of $7.5 million, which
represented the floor of the collar or $19.95 per share. NPS common stock was
trading at $17.13 on the day the first portion of the collar matured. The
unrealized loss of approximately $2.0 million dollars previously included in
other comprehensive income (loss) was recognized in the Consolidated Statement
of Operations and included in Other Income for the three and six months ended
December 31, 2004. The change during the period in the time value component of
the collar represents a gain of $307,000 and a loss of $822,000 for the three
and six months ended December 31, 2004 and a loss of $199,000 and $506,000 for
the three and six months ended December 31, 2003. This change is recorded as
"Other Income" in the Consolidated Statement of Operations. The remainder of the
collar will mature in three separate three-month intervals from February 2005
through August 2005, at which time the Company will receive the proceeds from
the sale of the securities. The amount due at each maturity date will be
determined based on the market value of NPS' common stock on such maturity date.
The contract requires the Company to maintain a minimum cash balance of $30.0
million and additional collateral up to $10.0 million (as defined) under certain
circumstances with the financial institution. The strike prices of the put and
call options are subject to certain adjustments in the event the Company
receives a dividend from NPS.

(13) NEW ACCOUNTING PRONOUNCEMENTS

In response to the enactment of the American Job Creation Act of 2004
(the "Jobs Act") on October 22, 2004 the Financial Accounting Standards Board
(FASB) issued FASB Staff Position (FSP) 109-1, Application of FASB Statement No.
109, Accounting for Income Taxes, for the Tax Deduction Provided to U.S. Based
Manufacturers by the American Job Creation Act of 2004.

FSP No. 109-1 clarifies how to apply SFAS No. 109 to the new law's tax
deduction for income attributable to "domestic production activities." The fully
phased-in deduction is up to nine percent of the lesser of taxable income or
"qualified production activities income." The staff position requires that the
deduction be accounted for as a special deduction in the period earned, not as a
tax-rate reduction. As a result, the Company will recognize a reduction in its
provision for income taxes for domestic production activities in the quarterly
periods in which the Company is eligible for the deduction.

In November 2004, the FASB issued SFAS No. 151, "Inventory Costs--An
Amendment of ARB No. 43, Chapter 4" ("SFAS 151"). SFAS 151 amends the guidance
in ARB No. 43, Chapter 4, "Inventory Pricing," to clarify the accounting for
abnormal amounts of idle facility expense, freight, handling costs, and wasted
material (spoilage). Among other provisions, the new rule requires that items
such as idle facility expense, excessive spoilage, double freight, and
rehandling costs be recognized as current-period charges regardless of whether
they meet the criterion of "so abnormal" as stated in ARB No. 43. Additionally,
SFAS 151 requires that the allocation of fixed production overheads to the costs
of conversion be based on the normal capacity of the production facilities. SFAS
151 is effective for fiscal years beginning after June 15, 2005 and is required
to be adopted by us in the first quarter of fiscal 2006, beginning on July
1, 2005. We are currently evaluating the effect that the adoption of SFAS 151
will have on our consolidated results of operations and financial condition but
do not expect SFAS 151 to have a material impact.

In December 2004, the FASB issued SFAS No. 123 (revised 2004),
"Share-Based Payment" ("SFAS 123R"), which replaces SFAS No. 123, "Accounting
for Stock-Based Compensation," ("SFAS 123") and supercedes APB Opinion No. 25,
"Accounting for Stock Issued to Employees." SFAS 123R requires all share-based
payments to employees, including grants of employee stock options, to be
recognized in the financial statements based on their fair values beginning with
the first interim or annual period after June 15, 2005, with early adoption
encouraged. The pro forma disclosures previously permitted under SFAS 123 no
longer will be an alternative to financial statement recognition. We are
required to adopt SFAS 123R no later than July 1, 2005. Under SFAS 123R, we must
determine the appropriate fair value model to be used for valuing share-based
payments, the amortization method for compensation cost and the transition
method to be used at date of adoption. The transition methods include
prospective and retroactive adoption options. Under the retroactive option,
prior periods may be restated either as of the beginning of the year of adoption
or for all periods presented. The prospective method requires that compensation
expense be recorded for all unvested stock options and restricted stock at the
beginning of the first quarter of adoption of SFAS 123R, while the retroactive
methods would record compensation expense for all unvested stock options and
restricted stock beginning with the first period restated. We are evaluating the
requirements of SFAS 123R and expect that the adoption of SFAS 123R will have a
material impact on our consolidated results of operations and earnings per
share. The Company has not yet determined the method of adoption or the effect
of adopting SFAS 123R, and have not determined whether the adoption will result
in amounts that are similar to the current pro forma disclosures under SFAS 123.

In December 2004, the FASB issued SFAS No. 153, "Exchanges of Nonmonetary
Assets--An Amendment of APB Opinion No. 29, Accounting for Nonmonetary
Transactions" ("SFAS 153"). SFAS 153 eliminates the exception from fair value
measurement for nonmonetary exchanges of similar productive assets in paragraph
21(b) of APB Opinion No. 29, "Accounting for Nonmonetary Transactions," and
replaces it with an exception for exchanges that do not have commercial
substance. SFAS 153 specifies that a nonmonetary exchange has commercial
substance if the future cash flows of the entity are expected to change
significantly as a result of the exchange. SFAS 153 is effective for the fiscal
periods beginning after June 15, 2005 and is required to be adopted by us in the
first quarter of fiscal 2006, beginning on July 1, 2005. We are currently
evaluating the effect that the adoption of SFAS 153 will have on our
consolidated results of operations and financial condition but does not expect
it to have a material impact.

ITEM 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

LIQUIDITY AND CAPITAL RESOURCES

Total cash reserves, which include cash, cash equivalents and
marketable securities, were $209.1 million as of December 31, 2004, as compared
to $186.2 million as of June 30, 2004. The increase is primarily due to net cash
provided by operating activities and proceeds from the liquidation of a portion
of the shares of NPS Common Stock that we own. We invest our excess cash
primarily in United States government-backed securities and investment-grade
corporate debt securities.

During the six months ended December 31, 2004, net cash provided by
operating activities was $18.0 million, compared to $18.9 million for the six
months ended December 31, 2003. Net cash provided by operations was principally
due to non-cash charges included in the net loss for the six months ended
December 31, 2004. The non-cash charges were depreciation and amortization of
$11.4 million and losses on the Company's sales of NPS common stock and related
losses on the equity collar agreement totaling $2.4 million.

Cash used in investing activities totaled $40.1 million for the six
months ended December 31, 2004 compared to cash provided by investing activities
of $3.3 million for the six months ended December 31, 2003. Cash used in
investing activities during the six months ended December 31, 2004, consisted of
$1.7 of capital expenditures and net purchases of marketable securities of $45.9
million, offset by $7.5 million in proceeds from the liquidation of a portion of
our shares of NPS Common Stock.

As of December 31, 2004, we had $400.0 million 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. Accrued interest
on the notes was $9.0 million as of December 31, 2004. 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. 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.

In August 2003, the Company entered into a Zero Cost Protective Collar
arrangement with a financial institution to reduce the exposure associated with
the 1.5 million shares of common stock of NPS Pharmaceuticals, Inc. ("NPS") the
Company received as part of a merger termination agreement with NPS. The first
interval of four intervals matured during the three months ended December 31,
2004 and we liquidated that portion of the investment and received proceeds of
$7.5 million. The remainder of the collar will mature in three separate
three-month intervals from February 2005 through August 2005, at which time the
Company will receive the proceeds from the sale of the securities which we
estimate with consideration to the collar to be $22.4 million to $28.5 million.
The amount due at each maturity date will be determined based on the market
value of NPS common stock on such maturity date. The contract requires the
Company to maintain a minimum cash balance of $30.0 million and additional
collateral up to $10.0 million (as defined) under certain circumstances with the
financial institution. The strike prices of the put and call options are subject
to certain adjustments in the event the Company receives a dividend from NPS.

12


Our current sources of liquidity are our cash and cash equivalents,
interest earned on such cash and cash equivalents, short-term investments,
marketable securities, sales of ADAGEN(R), ONCASPAR(R), DEPOCYT(R) and
ABELCET(R), royalties earned, which are primarily related to sales of
PEG-INTRON(R) and contract manufacturing revenue. In addition, we intend to sell
our positions in NPS and reinvest in marketable securities. Based upon our
currently planned research and development activities and related costs and our
current sources of liquidity, 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.

While we believe that our cash, cash equivalents and investments will
be adequate to satisfy our capital needs 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.

OFF-BALANCE SHEET ARRANGEMENTS

As part of our ongoing business, we do not participate in transactions
that generate relationships with unconsolidated entities or financial
partnerships, such as entities often referred to as structured finance or
special purpose entities ("SPE"), which would have been established for the
purpose of facilitating off-balance sheet arrangements or other contractually
narrow limited purposes. As of December 31, 2004 we are not involved in any SPE
transactions.

CONTRACTUAL OBLIGATIONS

Our major outstanding contractual obligations relate to our operating
leases, inventory purchase commitments, convertible debt, and license agreements
with collaborative partners. Since June 30, 2004, there has been no material
changes with respect to our contractual obligations as disclosed under
Management's Discussion and Analysis of Financial Condition and Results of
Operations - Contractual Obligations in our annual report on Form 10-K/A for the
year ended June 30, 2004.

RESULTS OF OPERATIONS

THREE MONTHS ENDED DECEMBER 31, 2004 AND 2003

Revenues. Total revenues for the three months ended December 31, 2004
were $43.0 million, as compared to $41.7 million for the three months ended
December 31, 2003. The components of revenues are product sales, contract
manufacturing revenue, royalties we earn on the sale of our products by others
and contract revenue.

13

Net product sales decreased by 3% to $27.0 million for the three months
ended December 31, 2004, as compared to $27.7 million for the three months ended
December 31, 2003. The decrease in sales was due to decreased sales of ABELCET.
Sales of ABELCET in North America decreased by 21% to $14.3 million for the
three months ended December 31, 2004, as compared to $18.0 million for the three
months ended December 31, 2003 as a result of weaker demand for the product due
to increased competition in the intravenous antifungal market. Sales of DEPOCYT
increased by 23% to $1.6 million for the three months ended December 31, 2004 as
compared to $1.3 million for the three months ended December 31, 2003. DEPOCYT's
growth over the prior year was primarily attributable to the Company's sales and
marketing efforts to support the product. Sales of ONCASPAR increased by 25% to
$5.5 million for the three months ended December 31, 2004 from $4.4 million in
the corresponding period in the prior year. The increase in sales of ONCASPAR
over the prior year was primarily driven by our focused marketing effort and
replacement of product that was returned due to the Company's voluntary recall
of certain batches of ONCASPAR during the quarter ended September 30, 2004.
Sales of ADAGEN increased by 40% for the three months ended December 31, 2004 to
$5.6 million as compared to $4.0 million for the three months ended December 31,
2003 due to an increase in the number of patients receiving ADAGEN therapy and
the timing of shipments.

Contract manufacturing revenue for the three months ended December 31,
2004 increased to $5.5 million, as compared to $2.2 million for the comparable
period of the prior year, due to the timing of orders from our contract
manufacturing customers. Contract manufacturing revenue is related to the
manufacture and sale of ABELCET for the international market and other contract
manufacturing revenue.

Royalties for the three months ended December 31, 2004, decreased to
$10.1 million as compared to $11.5 million in the same period in the prior year.
The decrease was primarily due to decreased sales of PEG-INTRON by
Schering-Plough, our marketing partner, due to competitive pressure from the
competing pegylated alpha interferon product, PEGASYS(R), which Hoffmann-La
Roche launched in December 2002.

Due to the competitive pressure and contracting market conditions, we
believe royalties from sales of PEG-INTRON in the United States and Europe may
continue to decrease in the near term. This decrease may be offset by the
ongoing launch of PEG-INTRON in combination with REBETOL(R) in Japan.
Schering-Plough began selling PEG-INTRON in Japan during December 2004. Since
its launch in the United States and Europe, the competing product has taken
market share away from PEG-INTRON and the overall market for pegylated alpha
interferon in the treatment of hepatitis C has not increased enough to offset
the effect this competition has had on sales of PEG-INTRON. As a result,
quarterly sales of PEG-INTRON and the royalties we receive on those sales have
declined in recent quarters. We cannot assure you that the competing product
will not continue to gain market share at the expense of PEG-INTRON, which could
result in lower PEG-INTRON sales and royalties to us.

Based on competitive pressure from the introduction of new products in
the antifungal market, namely Pfizer's VFEND(R) and Merck's CANCIDAS(R) and more
recent pricing pressure in the market for lipid formulations of amphotericin B,
we believe ABELCET may continue to be negatively impacted over the next year.

We expect ADAGEN sales to grow over the next year at similar levels to
those achieved for the year ended June 30, 2004. Assuming we are able to
successfully address certain manufacturing and product stability problems we
have experienced with ONCASPAR, which have resulted in the recent recalls
mentioned above, we expect ONCASPAR sales to continue to grow, but at a pace
slower then the growth achieved in fiscal 2004. ONCASPAR sales may decline,
however, if we are unable to correct these manufacturing and product stability
problems. We expect DEPOCYT sales to gain modestly from the current sales
levels. However, we cannot assure you that any particular sales levels of
ABELCET, ADAGEN, ONCASPAR, DEPOCYT or PEG-INTRON will be achieved or maintained.

Contract revenues for the three months ended December 31, 2004 were
$412,000 as compared to $253,000 for the three months ended December 31, 2003.
The increase was due to revenue related to a development agreement we entered
into with Pharmagene plc.

During the three months ended December 31, 2004, we had export sales
and royalties on export sales of $11.7 million, of which $9.3 million were in
Europe. Export sales and royalties recognized on export sales for the prior year
quarter were $9.1 million, of which $7.7 million were in Europe.

Cost of Sales and Manufacturing Revenue. Cost of sales and
manufacturing revenue, as a percentage of net sales and manufacturing revenue,
decreased to 38% for the three months ended December 31, 2004 as compared to 40%
for the same period last year. The decrease was principally due to lower
manufacturing cost for ABELCET. Included with cost of sales is $1.1 million for
the three months ended December 31, 2004 and 2003 related to amortization of
intangible assets acquired in connection with the ABELCET acquisition during
November 2002.

14


Research and Development. Research and development expenses increased
by 20% to $8.9 million for the three months ended December 31, 2004 from $7.4
million for the same period last year. The increase was primarily due to
spending of approximately $1.5 million related to our strategic partnership with
Inex Pharmaceuticals Corporation on Inex's proprietary oncology product MARQIBO.
In January 2005, the United States Food and Drug Administration (FDA) provided
an action letter to the company's partner, Inex, detailing that MARQIBO is "not
approvable" under the FDA's accelerated approval regulations based on the Phase
2b clinical-trial data submitted.

Selling, General and Administrative. Selling, general and
administrative expenses for the three months ended December 31, 2004 increased
by 20% to $13.8 million, as compared to $11.5 million for the same period last
year. The increase was primarily due to increased sales and marketing expense of
approximately $2.0 million and increased accounting and auditing fees of
approximately $300,000.

Amortization. Amortization expense remained unchanged at $3.4 million
for the three months ended December 31, 2004 and 2003. Amortization expense for
both periods related to intangible assets acquired in connection with the
ABELCET acquisition during November 2002. In addition, a portion of amortization
is classified in cost of sales and manufacturing revenue. Amortization of
intangible assets is calculated on a straight-line basis over the estimated
lives of the assets, which range from 3 to 15 years.

Other income (expense). Other income (expense) for the three months
ended December 31, 2004 was an expense of $5.3 million, as compared to an
expense of $4.2 million for the three months ended December 31, 2003. Other
income (expense) includes: net investment income, interest expense, and other
income.

Net investment income for the three months ended December 31, 2004
increased to $973,000 from $706,000 for the three months ended December 31, 2003
due to an increase in our interest bearing investments and higher interest
rates.

Interest expense was $5.0 million for each of the three months ended
December 31, 2004 and 2003. Interest expense is related to $400.0 million in
4.5% convertible subordinated notes, which were outstanding for each of the
periods.

Other income (expense) decreased to an expense of $1.3 million for the
three months ended December 31, 2004, as compared to income of $101,000 for the
three months ended December 31, 2003. The decrease in other income was related
to the loss on the liquidation of a portion of our investment in NPS common
stock and a loss on the derivative instrument we formed as a protective collar
arrangement to reduce our exposure associated with changes in the fair value of
these shares.

Income Taxes. During the three months ended December 31, 2004 we
recognized a tax benefit of approximately $243,000 compared to tax expense of
$1.2 million, for the three months ended December 31, 2003. We recognized a tax
benefit for the three months ended December 31, 2004 at an estimated annual
effective tax rate of 36%, which is based on the projected income tax benefit
and taxable loss for the fiscal year ending June 30, 2005. The tax provision for
the three months ended December 31, 2003 was based on the Company's projected
income tax expense and taxable income for the fiscal year ended June 30, 2004.

SIX MONTHS ENDED DECEMBER 31, 2004 AND 2003

Revenues. Total revenues for the six months ended December 31, 2004
were $83.4 million, as compared to $82.3 million for the six months ended
December 31, 2003. The components of revenues are product sales, contract
manufacturing revenue, royalties we earn on the sale of our products by others
and contract revenues.

Net product sales increased by 3% to $54.5 million for the six months
ended December 31, 2004, as compared to $52.7 million for the six months ended
December 31, 2003. The increase in sales was due to increased sales of three of
our internally marketed products: ADAGEN(R), DEPOCYT(R), and ONCASPAR(R). Sales
of ABELCET in North America decreased by 7% to $30.8 million for the six months
ended December 31, 2004, as compared to $33.0 million for the six months ended
December 31, 2003 as a result of weaker demand for the product due to increased
competition in the intravenous antifungal market. Sales of DEPOCYT increased by
54% to $4.0 million for the six months ended December 31, 2004 as compared to
$2.6 million for the six months ended December 31, 2003. Sales of ONCASPAR
increased by 17% to $9.8 million for the six months ended December 31, 2004, as
compared to $8.4 million in the corresponding period in the prior year. These
increased product sales resulted in large part from our focused sales and
marketing efforts to support ONCASPAR and DEPOCYT. Sales of ADAGEN increased by
14% for the six months ended December 31, 2004 to $9.9 million as compared to
$8.7 million for the six months ended December 31, 2003 due to an increase in
the number of patients receiving ADAGEN therapy and the timing of shipments.

15


Contract manufacturing revenue for the six months ended December 31,
2004 increased to $8.0 million, as compared to $3.8 million for the comparable
period of the prior year due to the timing of orders from our contract
manufacturing customers. Contract manufacturing revenue is related to the
manufacture and sale of ABELCET for the international market and other contract
manufacturing revenue.

Royalties for the six months ended December 31, 2004, decreased to
$20.2 million as compared to $25.3 million in the same period in the prior year.
The decrease was primarily due to decreased sales of PEG-INTRON by
Schering-Plough, our marketing partner, due to competitive pressure from the
competing pegylated alpha interferon product, PEGASYS(R), which Hoffmann-La
Rouche launched in December 2002.

Contract revenues for the six months ended December 31, 2004 increased
to $711,000 as compared to $521,000 in the previous year, due to revenue related
to the co-development agreement we entered into with Pharmagene plc.

During the six months ended December 31, 2004, we had export sales and
royalties on export sales of $22.5 million, of which $17.2 million were in
Europe. Export sales and royalties recognized on export sales for the prior year
were $19.1 million, of which $16.2 million were in Europe.

Cost of Sales and Manufacturing Revenue. Cost of sales and
manufacturing revenue, as a percentage of net sales and manufacturing revenue,
decreased to 37% for the six months ended December 31, 2004 compared to 40% for
the six months ended December 31, 2003 due to lower manufacturing cost for
ABELCET. Included with costs of sales is $2.2 million for the six months ended
December 31, 2004 and 2003 related to amortization of intangible assets
acquired in connection with the ABELCET acquisition during November 2002.

Research and Development. Research and development expenses increased
by 36% to $18.9 million for the six months ended December 31, 2004 from $13.9
million for the same period last year. The increase was primarily due to
increased spending of approximately $2.7 million related to our strategic
partnership with Inex on Inex's proprietary oncology product, MARQIBO, and
increased personnel-related expenses of approximately $2.3 million. In January
2005, the FDA provided an action letter to the company's partner, Inex,
detailing that MARQIBO is "not approvable" under the FDA's accelerated approval
regulations based on the Phase 2b clinical-trial data submitted.

Selling, General and Administrative. Selling, general and
administrative expenses for the six months ended December 31, 2004 increased by
15% to $26.0 million, as compared to $22.7 million in the same period last year.
The increase was primarily due to increased sales and marketing expense of
approximately $3.7 million which includes expenses associated with the potential
launch of MARQIBO. This increase was offset in part by a decrease in general and
administrative personnel and other related costs of approximately $414,000.

Amortization. Amortization expense remained unchanged at $6.7 million
for the six months ended December 31, 2004 and 2003. Amortization expense for
both periods relates to intangible assets acquired in connection with the
ABELCET acquisition during November 2002. In addition, a portion of amortization
is classified in cost of sales and manufacturing revenue. Amortization of
intangible assets is calculated on a straight line basis over the estimated
lives of the assets, which range from 3 to 5 years.

Other income (expense). Other income (expense) for the six months ended
December 31, 2004 was an expense of $10.1 million, as compared to an expense of
$8.3 million for the six months ended December 31, 2003. Other income (expense)
includes: net investment income, interest expense, and other income.

Net investment income for the six months ended December 31, 2004
increased to $1.7 million from $1.2 million for the six months ended December
31, 2003, due to an increase in our interest bearing investments, along with
higher interest rates.

Interest expense was $9.9 million for each of the six months ended
December 31, 2004 and 2003. Interest expense is related to $400.0 million in
4.5% convertible subordinated notes, which were outstanding for each of the
periods.

Other income (expense) decreased to an expense of $1.9 million for the
six months ended December 31, 2004, as compared to income of $408,000 for the
six months ended December 31, 2003. The decrease in other income was related to
the loss on the liquidation of a portion of our investment in NPS common stock
and a loss on the derivative instrument we formed as a protective collar
arrangement to reduce our exposure associated with changes in the fair value of
these shares.

16


Income Taxes. During the six months ended December 31, 2004 we
recognized a tax benefit of approximately $606,000 compared to tax expense $2.8
million, for the six months ended December 31, 2003. We recognized a tax
provision for the three months ended December 31, 2004 at an estimated annual
effective tax rate of 36%, which is based on the projected income tax benefit
and taxable loss for the fiscal year ending June 30, 2005. The tax provision for
the six months ended December 31, 2003 was recorded based on an estimated annual
effective tax rate of 35% which represented our anticipated Alternative Minimum
Tax Liability based on the anticipated taxable income for the full fiscal year.

CRITICAL ACCOUNTING POLICIES

In December 2001, the U.S. Securities and Exchange Commission ("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 a company's financial condition and
results of operations 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.

Our consolidated financial statements are presented in accordance with
accounting principles that are generally accepted in the United States. All
professional accounting standards effective as of December 31, 2004 have been
taken into consideration in preparing the consolidated financial statements. The
preparation of the consolidated financial statements requires estimates and
assumptions that affect the reported amounts of assets, liabilities, revenues,
expenses and related disclosures. Some of those estimates are subjective and
complex, and, consequently, actual results could differ from those estimates.
The following accounting policies have been highlighted as significant because
changes to certain judgments and assumptions inherent in these policies could
affect our consolidated financial statements.

Revenue from product sales and manufacturing revenue is recognized upon
passage of title and risk of loss to customers. This is generally at the time
products are shipped to customers. Provisions for discounts or chargebacks,
rebates and sales incentives to customers, and returns and other adjustments are
provided for in the period the related sales are recorded. Historical data is
readily available and reliable, and is used for estimating the amount of the
reduction in gross sales.

The majority of our net products sales are to distributors who resell
the products to the end customers. We provide rebates or chargebacks to members
of buying groups who purchase from our distributors that sell to their customers
at prices determined under a contract between Enzon and the customer. In
addition, state agencies, which administer various programs such as the U.S.
Medicaid and Medicare program also receive rebates or Medicaid rebates and
administrative fees. Chargeback amounts are usually based upon the volume of
purchases or by reference to a specific price for a product. Factors that
complicate the rebate calculations are which customer or government price terms
apply, and the estimated lag time between sale and payment of a rebate. Using
historical trends, adjusted for current changes, we estimate the amount of the
chargeback that will be paid, and record the amounts as a reduction to accounts
receivable and a reduction of gross sales when we record the sale of the
product. Settlement of the chargebacks generally occur from three to nine months
after sale. We regularly analyze the historical chargebacks trends and makes
adjustments to recorded reserves for changes in trends.

Medicaid rebates and administrative fees are recorded as a liability
and a reduction of gross sales when we record the sale of the product. Medicaid
rebates are typically paid up to six months later. In determining the
appropriate accrual amount we consider our historical Medicaid rebate and
administration fee payments by product as a percentage of our historical sales
as well as any significant changes in sales trend, an evaluation of the current
Medicaid rebate laws and interpretations and the percentage of our products that
are sold to Medicaid patients.

17


The following is a summary of reductions of gross sales accrued as of
June 30, 2004 (the end of our last fiscal year) and December 31, 2004:



December 31, 2004 June 30, 2004
---------------------- ---------------------

Accounts Receivable Reductions
Chargebacks $9,479 $7,802
Cash Discounts 318 414
Other (including returns) 1,241 1,323
---------------------- ---------------------
Total $11,038 $9,539
---------------------- ---------------------
Accrued Liabilities
Medicaid Rebates $ 2,354 $2,011
Administrative Fees 605 640
---------------------- ---------------------
Total $2,959 $2,651

There were no revisions to the estimates for gross to net sales
adjustment that would be material to income from operations for the three and
six months ended December 31, 2004 and 2003.

Royalties under our license agreements with third parties are
recognized when earned through the sale of the product by the licensee net of
any estimated future credits, chargebacks, sales discount rebates and refunds.

Contract revenues are recorded as the earnings process is completed.
Non-refundable milestone payments that represent the completion of a separate
earnings process are recognized as revenue when earned, upon the occurrence of
contract-specified events and when the milestone has substance. Non-refundable
payments received upon entering into license and other collaborative agreements
where we have continuing involvement are recorded as deferred revenue and
recognized ratably over the estimated service period.

Under the asset and liability method of Statement of Financial
Accounting Standards ("SFAS") No. 109 "Accounting for Income Taxes", 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 rates
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. We have
significant net deferred tax assets, primarily related to net operating loss and
other carryforwards, and continue to analyze what level of the valuation
allowance is needed taking into consideration the expected future performance of
the Company.

We assess the carrying value of our cost method investments in
accordance with SFAS No. 115 "Accounting for Certain Investments in Debt and
Equity" and SEC Staff Accounting Bulletin ("SAB") No. 59 "Accounting for
Non-current Marketable Equity Securities". An impairment write-down is recorded
when a decline in the value of an investment is determined to be
other-than-temporary. These determinations involve a significant degree of
judgment and are subject to change as facts and circumstances change.

In accordance with the provisions of SFAS No. 142 "Goodwill and other
Intangible Assets", goodwill and intangible assets determined to have an
indefinite useful life acquired in a purchase business combination, are not
subject to amortization, are tested at least annually for impairment, and are
tested for impairment more frequently if events and circumstances indicate that
the asset might be impaired. We completed our annual goodwill impairment test on
May 31, 2004, which indicated that goodwill was not impaired. An impairment loss
is recognized to the extent that the carrying amount exceeds the asset's fair
value. This determination is made at the Company level because the Company is in
one reporting unit and consists of two steps. First, we determine the fair value
of our reporting unit and compare it to its carrying amount. Second, if the
carrying amount of its reporting unit exceeds our fair value, an impairment loss
is recognized for any excess of the carrying amount of the reporting unit's
goodwill over the implied fair value of that goodwill. The implied fair value of
goodwill is determined by allocating the fair value of the reporting unit in a
manner similar to a purchase price allocation, in accordance with SFAS No. 141,
"Business Combinations". The residual fair value after this allocation is the
implied fair value of our goodwill. Recoverability of amortizable intangible
assets is determined by comparing the carrying amount of the asset to the future
undiscounted net cash flow to be generated by the asset. The evaluations involve
amounts that are based on management's best estimate and judgment. Actual
results may differ from these estimates. If recorded values are less than the
fair values, no impairment is indicated. SFAS No. 142 also requires that
intangible assets with estimated useful lives be amortized over their respective
estimated useful lives.

We apply the intrinsic value-based method of accounting prescribed by
Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued
to Employees", and related interpretations, in accounting for our fixed plan
stock options. As such, compensation expense would be recorded on the date of
grant of options to employees and members of the Board of Directors only if the
current market price of the underlying stock exceeded the exercise price. SFAS
No. 123, "Accounting for Stock-Based Compensation", established accounting for
stock-based employee compensation plans. As allowed by SFAS No. 123, we have
elected to continue to apply the intrinsic value-based method of accounting
described above, and have adopted the disclosure requirements of SFAS No. 123,
as amended in December 2004.

When the exercise price of employee or director stock options is less
than the fair value of the underlying stock on the grant date, we record
deferred compensation for the difference and amortize this amount to expense
over the vesting period of the options. Options or stock awards issued to
non-employees and consultants are recorded at their fair value as determined in
accordance with SFAS No. 123 and EITF No. 96-18, "Accounting for Equity
Instruments That Are Issued to Other Than Employees for Acquiring, or in
Conjunction with Selling, Goods or Services", and recognized over the related
vesting period.

CAUTIONARY FACTORS THAT MAY AFFECT FUTURE RESULTS (CAUTIONARY
STATEMENTS UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995)

Management's Discussion and Analysis of Financial Condition and Results
of Operations contains "forward-looking statements" within the meaning of the
Securities Litigation Reform Act of 1995. Forward-looking statements relate to
expectations or forecasts of future events. These statements use words such as
"anticipate," "believe," "could," "estimate," "expect," "forecast," "project,"
"intend," "plan," "potential," "will," and other words and terms of similar
meaning in connection with a discussion of potential future events or
circumstances or future operating or financial performance. You can also
identify forward-looking statements by the fact that they do not relate strictly
to historical or current facts.

Specific examples of such forward looking statements in this report
include statements relating to the potential impact on our revenues of
Schering-Plough's launch of PEG-INTRON in Japan, the potential impact on our
ability to sustain or grow our ABELCET revenues in light of continuing
competitive and pricing pressure in the intravenous antifungal market, the
future sales performance of our other products, the potential impact of the
manufacturing and stability problems with ONCASPAR we continue to experience,
the performance of our protective collar arrangement relating to the shares of
NPS common stock we hold, the continued sufficiency of our capital resources and
our ability to access the capital markets in the future. This is not necessarily
inclusive of all examples of forward looking statements that are or may be
contained in this report.

Any or all forward-looking statements contained in this discussion may
turn out to be wrong. Actual results may vary materially, and there are no
guarantees about our financial and operating performance or the performance
of our stock. All statements are made as of the date of signing of this report
and we do not assume any obligation to update any forward-looking statement.

Many factors could cause actual results to differ from the results or
developments discussed or predicted in the forward looking statements made in
this report. These factors include inaccurate assumptions and a broad variety of
other risks and uncertainties, including some that are known and some that are
not. Although it is not possible to predict or identify all such factors, many
of them are described under the caption "Risk Factors" in the "Management's
Discussion and Analysis of Financial Condition and Results of Operations"
section of our Annual Report on Form 10-K/A for the fiscal year ended June 30,
2004, which we filed with the SEC and which is incorporated herein by reference.
Readers of this report are advised to read such Risk Factors in connection with
this report. The following information supplements and updates such Risk
Factors:

o Although Schering-Plough has received approval for PEG-INTRON in Japan
in combination with REBETOL for the treatment of hepatitis C, there can
be no assurance that Schering-Plough will successfully market
PEG-INTRON in Japan. It is anticipated that Hoffmann-La Roche will
obtain marketing approval in Japan for a competing pegylated
interferon-based combination therapy for hepatitis C in the next one or
two years. Hoffmann-La Roche's subsidiary (Chugai Pharmaceutical Co.
LTD) currently markets other pharmaceutical products in Japan. Even if
Schering-Plough is successful in launching PEG-INTRON in Japan, it is
likely that the future launch in Japan of Hoffmann-La Roche's
competing pegylated interferon-based combination therapy will have a
negative impact on PEG-INTRON's Japanese market share and sales.

19


o We have begun to experience increasing pricing pressure with respect to
ABELCET. In particular, Fujisawa Healthcare Inc. and Gilead Sciences,
Inc., which jointly market a competing liposomal amphotericin B
product, have aggressively lowered the price of their product in
certain regions and for certain customers in the U.S. This has resulted
in the shrinkage or loss of certain of our customer accounts. We are
developing strategies to address this competitive threat, but there can
be no assurance as to when or whether we will be successful in stopping
or reversing this trend.

o We have received a notice from Bristol-Myers Squibb Company ("BMS")
terminating our amphotericin B supply agreement with BMS effective
March 1, 2006. We currently have an alternative source of supply of
amphotericin B and are seeking to qualify at least one additional
source of supply. The termination by BMS may give rise to future
increased costs for the acquisition of amphotericin B as well as
increased capital expenditures related to readying a new supplier's
facilities for cGMP production and regulatory approval of ABELCET
incorporating the alternative amphotericin B. Although there can be no
assurance as to the timing of these increased costs and additional
capital expenditures, we anticipate that these may be incurred
beginning in calendar 2007.

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. In August 2003, we entered into a Zero Cost Protective
Collar arrangement with a financial institution to reduce the exposure
associated with the 1.5 million shares of common stock of NPS we received as
part of the merger termination agreement with NPS. The terms of the collar
arrangement are structured so that our investment in NPS stock, when combined
with the value of the collar, should secure ultimate cash proceeds in the range
of 85% - 108% of the negotiated fair value per share of $23.47 (representing a
4.85% discount off the closing price of NPS common stock on the day before the
collar was executed) (See Note 12). 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
December 31, 2004 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
December 31, 2004 (in thousands):



2005 2006 2007 2008 TOTAL FAIR VALUE
--------- --------- ---------- --------- --------- -------------

Fixed Rate $76,521 $38,425 $20,627 $5,000 $140,573 $139,617
Average Interest Rate 0.89% 2.32% 2.69% 2.73% 1.61% -
Variable Rate - - - - - -
Average Interest Rate - - - - - -
--------- --------- ---------- --------- --------- -------------
$76,521 $38,425 $20,627 $5,000 $140,573 $139,617
========= ========= ========== ========= ========= =============


Our 4.5% convertible subordinated notes in the principal amount of
$400.0 million due July 1, 2008 have fixed interest rates. The fair value of the
notes was approximately $377.0 million at December 31, 2004. 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

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-15(e) under the Exchange Act) as of December
31, 2004, the end of the period covered by this report (the "Evaluation Date").
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
required to be included in our periodic SEC filings.

CHANGES IN INTERNAL CONTROLS

During the quarter ended December 31, 2004, we made changes in our
internal controls over financial reporting that are likely to materially affect
our internal control over financial reporting. The changes comprised the
institution of more comprehensive review and monitoring procedures to mitigate
the risk of certain errors of the type described below.

During the quarter ended December 31, 2004, in connection with the
preparation of our quarterly report for the quarter ended September 30, 2004, we
detected previous errors related to (i) accounting for our derivative hedging
instrument and (ii) assessing the realizeability of deferred tax assets related
to the unrealized loss on available-for-sale securities included in accumulated
other comprehensive loss.

One error related to the hedging instrument resulted in a misallocation
between other income and accumulated other comprehensive loss as of and for the
quarter and year ended June 30, 2004. The other error related to the assessment
of the realizeability of the deferred tax assets resulted in a decrease to
deferred tax assets and an increase to accumulated other comprehensive loss as
of June 30, 2004. Executive management and the Finance and Audit Committee
determined that there was a material weakness to our internal control over
financial reporting relating to the timely review and monitoring of certain
account analyses, including the derivative hedging instrument and the assessment
of the realizeability of deferred tax assets established through accumulated
other comprehensive loss. As mentioned above, we have instituted more
comprehensive review and monitoring procedures to mitigate the risk of errors in
these particular areas occurring in the future.
