(1) Organization and Basis of Presentation

The unaudited condensed consolidated financial statements have been
prepared from the books and records of Enzon Pharmaceuticals, Inc. (the
"Company") and its subsidiaries in accordance with accounting principles
generally accepted in the United States of America for interim financial
information pursuant to 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.

(2) Comprehensive Income

Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
Comprehensive Income", requires unrealized gains and losses on the Company's
available-for-sale securities to be included in other comprehensive income.

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

(3) New Accounting Pronouncements

In December 2003, the Financial Accounting Standards Board ("FASB") issued
FASB Interpretation No. 46 (revised December 2003) ("FIN46-R"), Consolidation of
Variable Interest Entities, which addresses how a business enterprise should
evaluate whether it has a controlling financial interest in an entity through
means other than voting rights and accordingly should consolidate the entity.
FIN 46-R replaces FASB Interpretation No. 46, Consolidation of Variable Interest
Entities ("FIN 46"), which was issued in January 2003. FIN 46-R requires that if
an entity has a controlling financial interest in a variable interest entity,
the assets, liabilities and results of activities of the variable interest
entity should be included in the consolidated financial statements of the
entity. The provisions of FIN 46-R are effective immediately to those entities
that are considered to be special-purpose entities. For all other arrangements,
the FIN 46-R provisions are required to be adopted at the beginning of the first
interim or annual period ending after March 15, 2004. As of March 31, 2004 the
Company is not a party to transactions contemplated under FIN 46-R.

In November 2002, the Emerging Issues Task Force ("EITF") reached a
consensus opinion on EITF 00-21, Revenue Arrangements with Multiple
Deliverables. The consensus provides that revenue arrangements with multiple
deliverables should be divided into separate units of accounting if certain
criteria are met. The consideration for the arrangement should be allocated to
the separate units of accounting based on their relative fair values, with
different provisions if the fair value of all deliverables is not known or if
the fair value is contingent on delivery of specified items or performance
conditions. Applicable revenue recognition criteria should be considered
separately for each separate unit of accounting. EITF 00-21 is effective for
revenue arrangements entered into in fiscal periods beginning after June 15,
2003. This adoption did not have any impact on our financial position or results
of operations.

(4) 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 and nine months ended March
31, 2004 and 2003, 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 certain Series A Preferred
Stock that were outstanding as of March 31, 2003. The number of shares issuable
upon conversion of the Company's 4.5% Convertible Subordinated Notes due 2008
(the "Notes") and the effect of the vesting of certain restricted stock using
the treasury stock method have not been included as the effect of their
inclusion would be antidilutive. As of March 31, 2004, the Company had
10,797,000 dilutive common shares outstanding that could potentially dilute
future earnings per share calculations.

(5) Stock Based Compensation

As permitted by Statement of Financial Accounting Standards ("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". 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. No stock option-based
employee compensation cost is reflected in net income, as all options granted to
employees had exercise prices equal to the market value of the underlying common
stock at the date of grant.

During the nine months ended March 31, 2004, the Company issued 312,500
shares of restricted common stock and restricted common stock units to certain
members of management. Total compensation expense of approximately $3.7 million
is being recognized over a five year vesting period.

During the nine months ended March 31, 2004, the Company granted 2,028,000
stock options to its employees at an average exercise price of $13.82 under its
stock option plans (fair value on the date of grants) of which 300,000 were
granted to executive officers and 25,000 were granted to non-employee directors
of the Company. The options vest over a period between one and four years.

In December 2003, the stockholders of the Company approved amendments to
the Company's 2001 Incentive Stock Plan ("Plan") to increase the number of
shares of common stock available for issuance under the Plan from 2,000,000 to
6,000,000 and to limit the maximum number of shares of restricted stock and
restricted stock units that may be granted under the Plan to 50% of the total
number of shares available for issuance.

(7) Acquisition of the ABELCET Product Line

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 "ABELCET
Product Line") from Elan Corporation, plc, for $360.0 million plus acquisition
costs of approximately $9.3 million.

The following unaudited pro forma results of operations of the Company for
the nine month period ended March 31, 2003, assumes the acquisition of the
ABELCET Product Line occurred as of July 1, 2002 and assumes the purchase price
has been allocated to the assets purchased based on fair values at the date of
acquisition (in thousands, except per share amounts):

(8) Intangible Assets

The Company's intangible assets are primarily related to its November 22,
2002 acquisition of the ABELCET Product Line, DEPOCYT and ONCASPAR and are
amortized over their estimated useful lives. The gross carrying amount,
estimated lives and accumulated amortization, by major intangible asset class at
March 31, 2004 were as follows:

-------- ------- --------

Total $224,286 $25,742 $198,544
======== ======= ========


Amortization of intangible assets for the three and nine month period
ended March 31, 2004 was $4.5 million and $13.4 million, respectively, a portion
of which is included in cost of goods sold. Assuming no changes in the gross
carrying amount of intangible assets, the amortization of intangible assets for
the next five fiscal years is estimated to be approximately $17.9 million per
year. Amortization of intangible assets for both the three and nine month period
ended March 31, 2003 was $4.5 million and $6.3 million, respectively.

(9) Goodwill

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," goodwill is not amortized, but
rather is reviewed at least annually for impairment.

(10) 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 nine months ended March 31,
2004 and 2003. Income tax payments for the nine months ended March 31, 2004 were
$3.6 million. There were no income tax payments made for the nine months ended
March 31, 2003.

(11) Income Taxes

During the three months ended March 31, 2004 the Company recorded a net
tax benefit of approximately $5.5 million related primarily to the reversal of a
deferred tax asset valuation allowance of approximately $3.8 million for the
write-down in a prior year of our investment in NEKTAR Therapeutics Convertible
Preferred Stock which was converted and the underlying common stock was sold
during the quarter, resulting in a financial reporting gain of approximately
$11.0 million. The benefit was also due to the reduction of our estimated
taxable income and effective tax rate to 29% as compared to 35% used in the
previous two quarters, due to a payment during the three months ended March 31,
2004 of $12.0 million to INEX Pharmaceuticals related to acquired in-process
research and development for Onco TCS (See Note 14). The tax provision
recognized for the nine months ended March 31, 2004 is based on the estimated
annual effective tax rate of 29%. In addition, the tax effect of the financial
reporting gain on the sale of NEKTAR Convertible Preferred Stock and the
acquired in process research and development charge was recognized during the
three months ended March 31, 2004, the period in which the items occurred.

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

At June 30, 2003, the Company recognized approximately $67.5 million as a
net deferred tax asset related to expected future profits, because management
concluded that it is more likely than not that the deferred tax assets will be
realized, including the net operating losses from operating activities and stock
option exercises, based on future operations. As of June 30, 2003 the Company
retained a valuation allowance of $12.8 million with respect to certain capital
losses and federal research and development credits as the ultimate utilization
of such losses and credits is uncertain. As discussed above, during February
2004, the Company reversed a portion of the valuation allowance associated with
the NEKTAR investment. 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 nine month period ended March 31, 2003
represents the Company's anticipated Alternative Minimum Tax liability based on
the anticipated taxable income for the full fiscal year.

During the three and nine month period ended March 31, 2004, the Company
received $254,000 for the sale of certain New Jersey state net operating loss
carryforwards and also purchased certain New Jersey state net operating loss
carryforwards for $1.5 million.

(12) 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 and Canada. 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 SFAS No. 131, "Disclosures about Segments of an Enterprise and
Related Information".

(13) Derivative Instruments

In August 2003, the Company entered into a Zero Cost Protective Collar
arrangement (the "Collar") with a financial institution to reduce the exposure
associated with the 1.5 million shares of common stock of NPS Pharmaceuticals,
Inc. ("NPS") it received as part of the merger termination agreement between the
Company and NPS. By entering into this equity collar arrangement and taking into
consideration the underlying put and call option strike prices, the terms 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
Company executed the Collar). The Collar is considered a derivative hedging
instrument under SFAS No. 133 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 2) or in the
Statement of Operations depending on its effectiveness. As of March 31, 2004,
the market value of NPS' common stock was $28.52 per share. When the underlying
shares become unrestricted and freely tradable, the Company is required to
deliver to the financial institution as posted collateral, a corresponding
number of shares of NPS common stock. During the three and nine month period
ended March 31, 2004, the Company sold and re-purchased 315,100 shares and
690,100 shares, respectively, of common stock of NPS. The unrealized gain
previously recognized under other comprehensive income with respect to these
shares aggregating $504,000 and $1.1 million for the three and nine months ended
March 31, 2004, respectively, was recognized in the Statements of Operations and
is being shown as "Other Income". With respect to the remaining 809,900 shares
of NPS common stock as of March 31, 2004, the increase in the aggregate value
above the base price of $23.47 per share up to the $25.35 per share Collar
limit, or $989,000, has been recorded in comprehensive income for the nine
months ended March 31, 2004, net of income taxes. The fair value of the Collar
above the $25.35 per share dollar limit represented a liability of $4.8 million
at March 31, 2004, which is included under "Other Liabilities" in the Condensed
Consolidated Balance Sheet. In addition, the difference in the fair value of the
Collar compared to the fair market value of the NPS common stock

representing a loss of $318,000 for the three months ended March 31, 2004 and a
gain of $83,000 for the nine month period ended March 31, 2004, was recorded as
"Other Income" in the Statement of Operations. The Collar will mature in four
separate three-month intervals beginning November 2004 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.

(14) INEX Agreement

During January 2004, the Company and Inex Pharmaceuticals Corporation
("INEX") entered into a strategic partnership to develop and commercialize
INEX's proprietary oncology product Onco TCS. The Company and INEX entered into
a Product Supply Agreement, a Development Agreement, and a Co-Promotion
Agreement. The agreements contain cross termination provisions under which
termination of one agreement triggers termination of all the agreements.

Under the terms of the agreements, the Company received the exclusive
commercialization rights for Onco TCS for all indications in the United States,
Canada and Mexico. The lead indication for Onco TCS is relapsed aggressive
non-Hodgkin's lymphoma (NHL) for which a "rolling" New Drug Application (NDA) to
the United States Food and Drug Administration (FDA) was filed on March 15,
2004. The product is also in numerous phase II clinical trials for several other
cancer indications, including first-line NHL.

Upon execution of the related agreements the Company made a $12.0 million
up-front payment to INEX which has been determined to be an acquisition of
in-process research and development as the payment was made prior to FDA
approval, and therefore expensed in the Company's Statement of Operations for
the quarter ended March 31, 2004. In addition, the Company will be required to
pay up to $20.0 million upon Onco TCS being approved by the FDA and development
milestones and sales based bonus payments could total $43.75 million, of which
$10.0 million is payable upon annual sales first reaching $125.0 million, and
$15.0 million is payable upon annual sales first reaching $250.0 million. The
Company will also be required to pay INEX a percentage of commercial sales of
Onco TCS and this percentage will increase as sales reach certain predetermined
thresholds.

The Company and INEX will share equally the future development costs to
obtain and maintain marketing approvals in North America for Onco TCS, and the
Company will pay all sales and marketing costs and certain other post-approval
clinical development costs typically associated with commercialization
activities. The Company plans to market Onco TCS to the oncology market through
its North American sales force, which currently markets ABELCET(R), ONCASPAR(R),
and DEPOCYT(R). INEX has the option of complementing the Company's sales efforts
by co-promoting Onco TCS through the formation of a dedicated North American
sales and medical science liaison force. The costs of building INEX's
co-promotion force will be shared equally by both companies and the Company will
record all sales in the licensed territories. INEX retains manufacturing rights
and the Company will reimburse INEX for the manufacture and supply of the drug
at manufacturing cost plus five percent.

The agreements will expire on a country by country basis upon the
expiration of the last patent covering the licensed product in each particular
country or 15 years after the first commercial sale in such country, whichever
is later. The agreements are also subject to earlier termination under various
circumstances. The Company may terminate the agreements at any time upon 90 days
notice, in connection with which the Company must pay a $2.0 million termination
fee. INEX has completed the submission of its NDA, therefore if Enzon terminates
it must pay the $2.0 million fee. In addition, if at any time the Company
determines that it has no interest in commercializing the product in any
country, then INEX may terminate the agreement with respect to such country.
Either party may


12

Notes To Condensed Consolidated Financial Statements
(Unaudited)

terminate the agreements upon a materialbreach and failure to cure by the other
party. In addition, either party may terminate the agreements upon the other
party's bankruptcy. Generally, the termination of the agreements with respect to
a particular country shall terminate the Company's license with respect to Onco
TCS, and preclude the Company from marketing the product, in that country.
However, if the Company terminates the agreements because of INEX's breach or
bankruptcy, INEX will be obligated to provide the Company a right of reference
to INEX's regulatory dossiers and facilitate a transfer to the Company of the
technology necessary to manufacture the product. In addition, after such
termination, INEX will be obligated to exercise commercially reasonable efforts
to ensure that the Company has a continuous supply of product until the Company,
exercising commercially reasonable efforts, has secured an alternative source of
supply.

(15) Elan/Medeus Manufacturing Agreements

During February 2004 Elan Corporation, plc, sold its ABELCET and MYOCET
European business to Medeus Pharma, Ltd. ("Medeus") As part of this transaction
the Company's long-term manufacturing and supply agreement with Elan was
assigned to Medeus. In connection with the closing of this sale the Company and
Elan settled a dispute over the manufacturing cost of products produced for Elan
resulting in the payment and recognition of manufacturing revenue related to
approximately $1.7 million of revenue not previously recognized given the
uncertainty of the contractual amount.

(16) Investment Income

During the three months ended March 31, 2004, the Company converted 20,055
shares or approximately 50% of its Nektar Therapeutics convertible preferred
stock investment to common stock which it sold resulting in gross proceeds of
approximately $17.4 million and a net gain of approximately $11.0 million.

(17) Subsequent Events

In connection with Mr. Higgins' departure as the Company's CEO the board
appointed a committee of four independent directors (Dr. Rosina Dixon, Robert
LeBuhn, Dr. David Golde and Robert Parkinson) to review and approve the terms of
Mr. Higgins departure. This committee negotiated and approved a separation
payment of $1.25 million, which is payable to Mr. Higgins upon his departure in
May 2004. Concurrent with Mr. Higgins' departure as CEO in May 2004, the Company
will reverse approximately $1.29 million of compensation expense previously
recorded related to restricted stock of the Company that will be forfeited by
Mr. Higgins as a result of his departure as the Company's CEO.

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. These forward looking statements are subject to various risks and
uncertainties that may cause actual results to differ materially from the
results predicted by the forward looking statements. 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, 2003, which is incorporated herein by reference,
contain cautionary statements identifying important risks, uncertainties and
other factors, that could prevent the future results indicated in such
forward-looking statements from being achieved. Other factors could also cause
actual results to vary materially from the future results indicated in such
forward-looking statements.

Liquidity and Capital Resources

Total cash reserves, which include cash, cash equivalents, short-term
investments, and marketable securities, were $174.5 million as of March 31,
2004, as compared to $153.3 million as of June 30, 2003. The increase is
primarily due to net proceeds from the sale of shares of common stock issuable
upon our conversion of preferred shares of Nektar Therapeutics of approximately
$17.4 million and cash flow from operations. We invest our excess cash primarily
in United States government-backed securities and investment-grade corporate
debt securities.

During the nine months ended March 31, 2004, net cash generated from
operating activities was $8.5 million, compared to $40.9 million for the nine
months ended March 31, 2003. The reduction in net cash generated operating
activities in 2004 compared to 2003 was primarily due to a reduction in net
income related to the deduction of a non-cash write-down of the carrying value
of investments in 2003 as well as purchase of $12.0 million of acquired in
process research and development related to the Onco TCS strategic partnership
and a decrease in income. During the nine months ended March 31, 2003, we
recorded as a non-cash write-down of approximately $27.2 million of our
investment in NEKTAR Therapeutics

Cash provided by investing activities totaled $7.7 million for the nine
months ended March 31, 2004 compared to cash utilization of $84.4 million for
the nine months ended March 31, 2003. Cash provided by investing activities
during the nine months ended March 31, 2004, was principally due to purchases
and sales from investments and marketable securities of $12.3 million
principally due to the sale of Nektar Therapeutics stock of $17.4 million offset
by $4.6 million of capital expenditures.

As of March 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 $4.5 million as of March 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. 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.

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. By entering into this equity collar arrangement
and taking into consideration the underlying put and call option strike prices,
the terms 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%


14


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 we executed the
Collar). The Collar is considered a derivative hedging instrument under SFAS No.
133 and as such, we periodically measure 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 2) or in the Statement of Operations
depending on its effectiveness. As of March 31, 2004, the market value of NPS'
common stock was $28.52 per share. When the underlying shares become
unrestricted and freely tradable, we are required to deliver to the financial
institution as posted collateral, a corresponding number of shares of NPS common
stock. During the three and nine month period ended March 31, 2004, we sold and
re-purchased 315,100 shares and 690,100 shares respectively of common stock of
NPS. The unrealized gain previously recognized under other comprehensive income
with respect to these shares aggregating $504,000 and $1.1 million for the three
and nine months ended March 31, 2004, respectively, was recognized in the
Statements of Operations and is being shown as "Other Income". With respect to
the remaining 809,900 shares of NPS common stock as of March 31, 2004, the
increase in the aggregate value above the base price of $23.47 per share up to
the $25.35 per share Collar limit, or $989,000, has been recorded in
comprehensive income for the nine months ended March 31, 2004, net of income
taxes. The fair value of the Collar above the $25.35 per share Collar limit
represented a liability of $4.8 million at March 31, 2004, which is included
under "Other Liabilities" in the Condensed Consolidated Balance Sheet. In
addition, the difference in the fair value of the Collar compared to the fair
market value of the NPS common stock representing a loss of $318,000 for the
three months ended March 31, 2004 and a gain of $83,000 for the nine month
period ended March 31, 2004, was recorded as "Other Income" in the Statement of
Operations. The Collar will mature in four separate three-month intervals
beginning November 2004 through August 2005, at which time we 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 us 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 we receive
a dividend from NPS.

Our current sources of liquidity are our cash reserves, and interest
earned on such cash reserves, short-term investments, marketable securities,
sales of ADAGEN(R), ONCASPAR(R), DEPOCYT(R) and ABELCET(R), royalties earned
primarily on sales of PEG-INTRON(R), 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, 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 reserves 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 March 31, 2004, we are not involved in any SPE
transactions.

Contractual Obligations

Our major outstanding contractual obligations relate to our operating
leases, our convertible debt and our license and development agreements with
collaborative partners. Under our strategic partnership with INEX which was
entered into during the three months ended March 31, 2004 we are obligated to
pay up to $20.0 million payment upon Onco TCS receiving approval from the FDA
and additional development milestones and sales based bonus


15


payments could total $43.75 million, of which $10.0 million is payable upon
annual sales first reaching $125.0 million and $15.0 million is payable upon
annual sales first reaching $250.0 million. INEX will also receive a percentage
of commercial sales of Onco TCS and this percentage will increase as sales reach
certain predetermined thresholds. Other than the additional INEX contracted
obligations our contractual obligations as of March 31, 2004 are not materially
different from our contractual obligations as of June 30, 2003 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 for
the fiscal year ended June 30, 2003.

Results of Operations

Three months ended March 31, 2004 and March 31, 2003

Revenues. Total revenues for the three months ended March 31, 2004
increased by 3% to $44.4 million, as compared to $43.2 million for the three
months ended March 31, 2003. The components of revenues are product sales and
certain contract manufacturing revenues, royalties we earn on the sale of
products by others and contract revenues.

Net product sales and manufacturing revenue increased by 24% to $33.0
million for the three months ended March 31, 2004, as compared to $26.6 million
for the three months ended March 31, 2003. The increase in net sales was due to
increased sales of ABELCET and DEPOCYT in North America and increased sales of
ONCASPAR. During the three months ended March 31, 2004, we recorded $22.6
million of sales related to the ABELCET Product Line as compared to $18.3
million for the corresponding period in the prior year. Of the total ABELCET
Product Line sales, sales in North America accounted for $17.6 million for the
three months ended March 31, 2004 as compared to $13.5 for the three months
ended March 31, 2003. Contract manufacturing revenue related to the manufacture
and sale of ABELCET for the international market and other contract
manufacturing revenue was $5.0 million for the three month period ended March
31, 2004 as compared to $4.8 for the three months ended March 31, 2003.
Approximately $1.7 million of the $5.0 million of revenues recorded during the
three months ended March 31, 2004 related to the settlement of amounts
previously disputed by Elan. During the three months ended March 31, 2004, we
recorded DEPOCYT sales of $1.4 million as compared to $1.2 million in the
corresponding period in the prior year. Sales of ONCASPAR increased by 73% to
$4.9 million for the three months ended March 31, 2004 from $2.8 million in the
corresponding period in the prior year. This was a result of our resumption of
marketing efforts in connection with our reacquiring from Aventis in June 2002
the right to market and distribute ONCASPAR for certain territories previously
licensed to Aventis. Sales of ADAGEN decreased by 4% for the three months ended
March 31, 2004 to $4.1 million as compared to $4.3 million for the three months
ended March 31, 2003 due to the timing of shipments.

Royalties for the three months ended March 31, 2004, decreased to $11.1
million as compared to $16.2 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 sales of a competitive product, PEGASYS(R).

During December 2002, Hoffman-LaRoche launched PEGASYS(R), a pegylated
version of its interferon product ROFERON-A(R). Since its launch, PEGASYS has
taken market share away from PEG-INTRON. As a result, quarterly sales of
PEG-INTRON and the royalties we receive on those sales have declined in recent
quarters. We have no involvement in the marketing and sales of PEG-INTRON, which
are the responsibility of Schering-Plough. We cannot assure you that PEGASYS
will not continue to gain market share at the expense of PEG-INTRON, which could
result in lower PEG-INTRON sales and lower royalties.

As a result of our focused marketing efforts for ABELCET, we believe that
we have been able to stabilize the pressure from the introduction of new
products in the antifungal market and that the product is now back on a growth
pattern. We expect sales of DEPOCYT, which are currently running at an annual
rate of approximately $5.0 million, to increase as we continue to roll out our
focused marketing efforts. We expect ADAGEN and ONCASPAR sales to grow in this
fiscal year at levels similar to those achieved during the last fiscal year.
However, we cannot assure you that any particular sales levels of ABELCET,
ADAGEN, ONCASPAR, DEPOCYT or PEG-INTRON will be achieved or maintained.


16


Contract revenues for the three months ended March 31, 2004, remained
relatively stable at $248,000 as compared to $284,000 in the corresponding
period in the previous year. Contract revenue is principally comprised of a
portion of the $3.5 million licensing payment received in January 2003 from the
licensing of our PEG technology to SkyePharma which is being recognized as
revenue over the term of the related agreement.

During the three months ended March 31, 2004, we had export sales and
royalties on export sales of $9.0 million, of which $7.4 million were sales in
Europe or royalties on sales in Europe. Export sales and royalties on export
sales for the three months ended March 31, 2003 were $8.6 million, of which $7.5
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 March 31, 2004 as compared to 42% for the same period
last year. The decrease was principally due to higher 2003 inventory costs as a
result of certain purchase accounting adjustments to the inventory acquired with
the ABELCET Product Line, which was sold during the three months ended March 31,
2003, as well as lower cost of manufacturing revenue due to the settlement of
$1.7 million in disputed Elan invoices previously discussed.

Research and Development. Research and development expenses increased by
110% to $10.8 million for the three months ended March 31, 2004 from $5.1
million for the same period last year. The increase was primarily due to (i)
increased spending of approximately $1.6 million related to our strategic
partnership with INEX on INEX's proprietary oncology product Onco TCS, (ii)
increased spending of approximately $819,000 related to our single chain
antibody collaboration with Micromet AG, (iii) increased spending on our two
late stage development programs, Pegamotecan and ATG Fresenius S, of
approximately $1.4 million, and (iv) increased payroll related expenses of
approximately $1.8 million.

Selling, General and Administrative. Selling, general and administrative
expenses for the three months ended March 31, 2004 increased by 32% to $12.5
million, as compared to $9.5 million in the same period last year. The increase
was primarily due to (i) increased sales and marketing expense of approximately
$970,000 related to the ABELCET Product Line including the lunch of the Clear II
registry, (ii) increased sales and marketing expense of approximately $272,000
related to our oncology sales force for ONCASPAR and DEPOCYT, and (iii)
increased general and administrative personnel and other costs of approximately
$1.8 million.

Merger Expenses. Merger expenses represent costs incurred related to our
mutual termination of the merger agreement with NPS Pharmaceuticals. During the
three months ended March 31, 2003, we incurred $1.4 million of merger related
expenses. There were no such costs in the current period.

Amortization. Amortization expense for the three months ended March 31,
2004 was $3.4 million as compared to $4.0 million in the comparable period last
year. Amortization relates principally to the intangible assets acquired in
November 2002 as part of the ABELCET Product Line. Amortization of intangible
assets is provided over their estimated lives ranging from 1-15 years on a
straight-line basis.

Acquired In Process Research and Development. Acquired in process research
and development for the three months ended March 31, 2004 of $12.0 million was
due to the up-front payment for the execution of a strategic partnership
agreements entered into with INEX related to Onco TCS.

Other Income/Expense. Investment income for the three months ended March
31, 2004 increased to $11.6 million, as compared to $632,000 for the prior year.
The increase was primarily due to the sale of Nektar Therapeutics stock and the
sale of the shares of common stock issued upon such conversion. Interest expense
remained unchanged from the comparable period last year. Interest expense is
related to the $400.0 million in 4.5% convertible subordinated notes, which were
outstanding for both periods. Other expense of $337,000 for the three months
ended March 31, 2004 was principally due to a loss recognized with respect to
the collar associated with the 1.5 million shares of NPS common stock we hold.


17


Income Taxes. During the three months ended March 31, 2004 the Company
recorded a net tax benefit of approximately $5.5 million related primarily to
the reversal of a deferred tax asset valuation allowance of approximately $3.8
million for the write-down in a prior year of our investment in NEKTAR
Convertible Preferred Stock which was converted and the underlying common stock
was sold during the quarter resulting in a financial reporting gain of
approximately $11.0 million. The benefit was also due the reduction of our
estimated taxable income and effective tax rate to 29% as compared to 35% used
in the previous two quarters, due to a payment during the three months ended
March 31, 2004 of $12.0 million to INEX Pharmaceuticals related to acquired
in-process research and development for Onco TCS. The tax provision for the
three months ended March 31, 2003 represented our anticipated Alternative
Minimum Tax liability based on the anticipated taxable income for the full
fiscal year.

Acquisition of ABELCET(R) Business

On November 22, 2002, we 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 ABELCET
Product Line") from Elan Corporation, plc ("Elan") for $360.0 million, plus
approximately $9.3 million of acquisition costs. This transaction was accounted
for as a business combination.

Unless otherwise indicated, the discussions in Management's Discussion and
Analysis of Financial Condition and Results of Operations for the three months
ended March 31, 2004 and 2003 and the nine months ended March 31, 2004 and
financial condition at March 31, 2004 include the results of operations of the
ABELCET Product Line. Comparisons are made to the results of operations and the
financial condition for the nine months ended March 31, 2003, which include
approximately only four months of operations, of the ABELCET Product Line
commencing from our acquisition of the Product Line on November 22, 2002.

Nine months ended March 31, 2004 and March 31, 2003

Revenues. Total revenues for the nine months ended March 31, 2004
increased by 27% to $126.7 million, as compared to $99.7 million for the nine
months ended March 31, 2003. The components of revenues are product sales and
certain contract manufacturing revenues, royalties we earn on the sale of
products by others and contract revenues.

Net product sales and manufacturing revenue increased by 114% to $89.5
million for the nine months ended March 31, 2004, as compared to $41.7 million
for the nine months ended March 31, 2003. The increase in net sales was due to
increased sales of ABELCET and DEPOCYT during the entire nine months ended March
31, 2004, and increased sales of ADAGEN and ONCASPAR. During November 2002, we
acquired the ABELCET Product Line from Elan. During the nine months ended March
31, 2004, we recorded $59.4 million of sales related to the ABELCET Product Line
as compared to $19.6 million for the prior year. Of the total ABELCET Product
Line sales, sales in North America accounted for $50.6 million for the nine
months ended March 31, 2004 as compared to $14.1 for the nine months ended March
31, 2003. Contract manufacturing revenue related to the manufacture and sale of
ABELCET to Elan for the international market and other contract manufacturing
revenue was $8.8 million for the nine month period ended March 31, 2004 as
compared to $5.5 for the comparable period of the prior year. Approximately $1.7
million of the $8.8 million of revenues recorded during the nine months related
to the settlement of amounts previously disputed by Elan. In January 2003, we
obtained an exclusive license to sell, market and distribute SkyePharma's
DEPOCYT. During the nine months ended March 31, 2004, we recorded DEPOCYT sales
of $4.0 million as compared to $1.2 million for the same period last year. Sales
of ONCASPAR increased by 53% to $13.3 million for the nine months ended March
31, 2004 from $8.7 million in the corresponding period in the prior year. This
was a result of our resumption of our marketing efforts subsequent to our
reacquiring from Aventis in June 2002 the right to market and distribute
ONCASPAR for certain territories which we had previously licensed to Aventis.
Sales of ADAGEN increased by 4% for the nine months ended March 31, 2004 to
$12.8 million as compared to $12.2 million for the nine months ended March 31,
2003 due to the timing of shipments.

Royalties for the nine months ended March 31, 2004, decreased to $36.5
million as compared to $57.6 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 the introduction of a competitive product,
PEGASYS.

Contract revenues for the nine months ended March 31, 2004 increased to
$769,000 as compared to $417,000 in the corresponding period in the previous
year. The increase was related to revenue received from the licensing of our PEG
technology to SkyePharma. In connection with such licensing, we received a
payment of $3.5 million in January 2003 which is being recognized as revenue
over the term of the related agreement.

During the nine months ended March 31, 2004, we had export sales and
royalties on export sales of $27.0 million, of which $22.5 million were sales in
Europe or royalties on sales in Europe. Export sales and royalties recognized on
export sales for the corresponding period in the prior year were $24.2 million,
of which $21.5 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 39%
for the nine months ended March 31, 2004 as compared to 43% for the comparable
period last year. The decrease was due to certain purchase accounting
adjustments to the inventory acquired with the ABELCET Product Line, which was
sold during nine months ended March 31, 2003.

Research and Development. Research and development expenses increased by
66% to $24.7 million for the nine months ended March 31, 2004 from $14.9 million
for the comparable period last year. The increase was primarily due to (i)
increased spending of approximately $2.4 million related to our single chain
antibody collaboration with Micromet AG, (ii) increased spending on our two late
stage development programs, Pegamotecan and ATG Fresenius S, of approximately
$2.8 million, (iii) increased spending of approximately $1.6 million related to
our strategic partnership with INEX on INEX's proprietary oncology product Onco
TCS, and (iv) increased payroll related expenses of approximately $3.0 million.

Selling, General and Administrative. Selling, general and administrative
expenses for the nine months ended March 31, 2004 increased by 69% to $35.2
million, as compared to $20.8 million in the comparable period last year. The
increase was primarily due to (i) increased sales and marketing expense of
approximately $10.5 million related to the sales force acquired from Elan as
part of our acquisition of the ABELCET Product Line, (ii) increased sales and
marketing expense of approximately $2.1 million related to the establishment of
an oncology sales force for ONCASPAR and DEPOCYT and (iii) increased general and
administrative personnel and other costs of approximately $1.8 million.

Merger Expenses. Merger expenses represent costs incurred related to our
mutual termination of the merger agreement with NPS Pharmaceuticals. During the
nine months ended March 31, 2003, we incurred $1.4 million of merger related
expenses. There were no such expenses in the current period.

Amortization. Amortization expense increased to $10.1 million for the nine
months ended March 31, 2004 as compared to $5.3 million in the same period last
year as a result of the amortization of the intangible assets acquired in
November 2002 as part of the ABELCET Product Line. Amortization of intangible
assets is provided over their estimated lives ranging from 1-15 years on a
straight-line basis.

Acquired In Process Research and Development. Acquired in process research
and development for the nine months ended March 31, 2004 of $12.0 million was
due to an up-front payment for the execution of a strategic partnership
agreements entered into with INEX related to Onco TCS.

Other Income/Expense. Investment income for the nine months ended March
31, 2004 increased to $12.7 million, as compared to $8.4 million for the prior
year. The increase was primarily due to the sale of Nektar Therapeutics stock
and the sale of the shares of common stock issued upon such conversions.
Interest expense

19


remained unchanged from the comparable period last year. Interest expense is
related to the $400.0 million in 4.5% convertible subordinated notes, which were
outstanding for both periods. Other income of $71,000 for the nine months ended
March 31, 2004, represents the gain recognized on the Collar arrangement related
to the 1.5 million shares of NPS common stock we hold.

Income Taxes. During the nine months ended March 31, 2004 the Company
recorded a net tax benefit of approximately $2.7 million related primarily to
the reversal of a deferred tax asset valuation allowance of approximately $3.8
million for the write-down in a prior year of our investment in NEKTAR
Therapeutics Convertible Preferred Stock which was converted and the underlying
common stock was sold during the nine months resulting in a financial reporting
gain of approximately $11.0 million. The benefit was also due to the reduction
of our estimated taxable income and effective tax rate to 29% as compared to 35%
used in the previous two quarters, due to a payment during the nine months ended
March 31, 2004 of $12.0 million to INEX Pharmaceuticals related to acquired
in-process research and development for Onco TCS (See Note 14). The tax
provision recognized for the nine months ended March 31, 2004 is based on the
estimated annual effective tax rate of 29%.

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 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, 2003 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.

Revenues from product sales and manufacturing revenue are recognized based
on shipping terms and a provision is made at that time for estimated future
credits, chargebacks, sales discounts, rebates and returns. These sales
provision accruals are presented as a reduction of the accounts receivable
balances. We continually monitor the adequacy of the accruals by comparing the
actual payments to the estimates used in establishing the accruals. We utilize
the following criteria to determine appropriate revenue recognition: pervasive
evidence of an arrangement exists, delivery has occurred, selling price is fixed
and determinable and collection is reasonably assured.

Royalties under our license agreements with third parties are recognized
when earned through the sale of the product by the licensor net of any estimated
future credits, chargebacks, sales discount rebates and refunds. Since we do not
sell or market the products, we rely on disclosures from our marketing partners
to estimate such sales allowances.

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, 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 carryforwards, and continue to analyze the level of the valuation
allowance needed taking into consideration the expected future performance of
the Company.

We assess the carrying value of our investments in accordance with SFAS
No. 115 and SEC Staff Accounting Bulletin No. 59. 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 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. Goodwill is
reviewed for impairment by comparing the carrying value to its fair value.
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.

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 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 typically invest the
majority of our investments in the shorter-end of the maturity spectrum, and at
March 31, 2004 all of our holdings were in instruments maturing in three 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
March 31, 2004 (in thousands):


2004 2005 2006 2007 2008 Total Fair Value
---- ---- ---- ---- ---- ----- ----------

Fixed Rate 4,569 $27,602 $38,458 $12,274 $ 8,015 $90,918 $91,099
Average Interest Rate 2.52% 2.22% 2.18% 2.29% 3.38% 2.33% --
Variable Rate -- -- -- -- -- --
Average Interest Rate -- -- -- -- -- --
-------------------------------------------------------------------------
$ 4,569 $27,602 $38,458 $12,274 $ 8,015 $90,918 $91,099
=========================================================================


Our 4.5% convertible subordinated notes in the principal amount of $400.0
million due July 1, 2008 have a fixed interest rate. The fair value of the notes
was approximately $383.9 million at March 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.

As discussed in Liquidity and Capital Resources, 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.

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-15(e) under the Exchange Act) as of December
31, 2003, 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
relating to us required to be included in our periodic SEC filings.

(b) Changes in internal controls over financial reporting.

There were no changes in our internal controls over financial reporting during
the period covered by this report that have materially affected, or are
reasonably likely to materially affect our internal control over financial
reporting.
