AMERICAN PHARMACEUTICAL PARTNERS, INC.



NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS



March 31, 2005



(Unaudited)



|(1) | Basis of Presentation
|--- | ---------------------



The accompanying unaudited condensed consolidated financial statements of American Pharmaceutical Partners, Inc. have been prepared in accordance with generally accepted
accounting principles for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all of the information and notes required by accounting principles
generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for
the three-month period ended March 31, 2005 are not necessarily indicative of the results that may be expected for the year ended December 31, 2005.



The balance sheet information at December 31, 2004 has been derived from the audited financial statements at that date but does not include all of the information and
notes required by generally accepted accounting principles for complete financial statements.



A wholly owned subsidiary of American Pharmaceutical Partners holds a 50% interest in Drug Source Company, LLC. Drug Source Company is a joint venture with three other partners established in June 2000 to purchase raw
materials for resale to pharmaceutical companies, including us. Because our 50% interest in Drug Source Company does not provide financial or operational control of the entity, we account for our interest in Drug Source Company under the equity
method. Our equity in the net income of Drug Source Company, net of intercompany profit on purchases of inventory, is classified in operating expenses in the accompanying condensed consolidated statements of income. Research and development expense
includes raw material purchases from Drug Source Company of $0.7 million and $0.3 million for the three-month periods ended March 31, 2005 and 2004, respectively. Ending inventory included raw material purchased from Drug Source Company of $5.2
million at March 31, 2005 and $2.9 million at December 31, 2004.



For further
information, refer to the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2004.



|(2) | Quarterly Periods
|--- | -----------------



We use a 52-week, 53-week fiscal year that ends on the Saturday nearest to December 31. For quarterly reporting purposes, the quarterly periods end on the Saturday nearest to the end of the quarter. For clarity of
presentation, comparative periods are presented as if the quarters ended on March 31. Both of the three-month periods ended March 31, 2005 and 2004 included 13 weeks.

Product License and Manufacturing Agreements



We hold the exclusive North American marketing rights and the worldwide manufacturing rights for ABRAXANE. The FDA approved ABRAXANE for the filed indication on January 7, 2005 and ABRAXANE was launched on February 7, 2005. ABRAXANE is licensed from American BioScience, which is responsible for conducting the
clinical studies of and obtaining regulatory approval for ABRAXANE.



In November 2001, we signed a perpetual
license agreement with American BioScience under which we acquired the exclusive rights to market and sell ABRAXANE in North America for indications relating to breast, lung, ovarian, prostate and other cancers. Under the agreement, we made an initial payment to
American BioScience of $60.0 million and committed to profit sharing and future milestone payments contingent upon achievement of specified regulatory, publication and sales objectives for licensed indications. American BioScience is responsible for
conducting clinical studies in support of ABRAXANE and for substantially all costs associated with the development and obtaining regulatory approval for ABRAXANE, except that we provided $2.0 million of ABRAXANE for use in clinical trials, the cost of which we charged to research and development expense in 2001.



Under the license agreement, profit on our sales of ABRAXANE North America will be shared equally between American BioScience and us. The
license agreement defines profit as ABRAXANE net
sales less cost of goods sold, selling expenses (including accumulated pre-launch production and other expenses

which we have expensed as incurred, but which will be charged against first profit under the agreement) and an allocation of related general and
administrative expenses. At December 31, 2004, accumulated ABRAXANE expenses, which are being offset against future ABRAXANE profit sharing, totaled $49.1 million. We anticipate that ABRAXANE profit, as defined in the license agreement, will exceed this accumulated expense in late 2005, at which point we will begin expensing American BioSciences share of any profit
earned in our statements of income as an element of cost of sales. Any costs and expenses related to product recalls and product liability claims generally will be split equally between American BioScience and us and expensed as incurred.



Under the license agreement, American BioScience earned milestone payments
upon the filing and approval of ABRAXANE for the
metastatic breast cancer indication. The first such milestone of $10.0 million was achieved in May 2004 when the FDA accepted American BioSciences NDA for the metastatic breast cancer indication. This payment was expensed and paid in the
second quarter of 2004. The FDA then approved ABRAXANE for the filed indication in January 2005, triggering a $15.0 million milestone payment in the first quarter of 2005, which has been capitalized and is being amortized over seven years.



Regulatory or publication achievements related to other licensed indications under study,
including lung, ovarian and prostate cancers, will trigger further milestone payments to American BioScience. Such payments generally total $17.5 million per agreed indication. As with the indication for breast cancer, those payments earned prior to
FDA approval for each indication will be expensed, while amounts earned upon FDA approval of those indications will be capitalized and amortized over the expected life of the product. We have the option not to make one or more of the milestone
payments tied to certain indications under study if sales of the product do not meet specified levels.



Upon achievement of major annual one-time ABRAXANE sales milestones, we are required to make additional payments which, in the aggregate, could total $110.0 million should annual ABRAXANE sales exceed $1.0 billion. The first sales milestone payment of $10.0 million would be triggered upon achievement of
annual calendar year ABRAXANE sales in excess of
$200.0 million and the second sales milestone of $20.0 million upon the achievement of annual calendar year sales in excess of $400.0 million. Any future sales-based milestone payments will be expensed in the period in which the sales milestone is
achieved.



The terms of the license agreement were negotiated to reflect the
value of the licensed product rights acquired, then in late-stage development, American BioSciences remaining obligation to complete the NDA filing and the potential sales of the product under licensed clinical indications. The license
agreement was a product of several months of extensive negotiation with American BioScience involving outside counsel, investment banks and a nationally recognized valuation firm. Based upon the analysis and recommendations of our advisors, we
believe that the overall terms of the agreement were fair to us, including in comparison to similar licenses between unrelated parties. The agreement was unanimously approved by the disinterested members of our Board of Directors, with those
directors who also have an affiliation with American BioScience recusing themselves from the vote. There are no restrictions on how American BioScience would use payments made under the license agreement and we understand such payments have been and
will be used both to fund the development of ABRAXANE in relation to our licensed product rights and for other purposes.



In December 2001, in conjunction with our initial public offering, we recorded an initial payment due American BioScience of $60.0 million. In our financial statements, the license agreement was accounted for as an
asset contributed by a principal shareholder using the shareholders historical cost basis, which was zero, and the $60.0 million payment was accounted for as a distribution of stockholders equity. For income tax purposes, the payment was
recorded as an asset and is being amortized over a 15-year period. Because there was no corresponding charge to income, the income tax benefit of this payment is being credited to stockholders equity as realized.



In November 2001, along with the license agreement for ABRAXANE, we also entered into a manufacturing agreement with American BioScience
under which we agreed to manufacture ABRAXANE for
American BioScience and its licensees for sales outside North America. Under this agreement, we have the right to manufacture ABRAXANE worldwide. For sales outside of our licensed territories, we will charge American BioScience and its licensees a customary margin on our manufacturing

costs based on whether the product will be used for clinical trials or commercial sale. The initial term of this agreement is ten years and may be extended
for successive two-year terms by American BioScience.



Loan to American
BioScience



Prior to our 2001 licensing of ABRAXANE, we made loans to American BioScience, our majority
shareholder, to support development of ABRAXANE.
Subsequent to formalization of the license and manufacturing agreements in November 2001, we received a demand promissory note, which replaced prior notes, from American BioScience for the outstanding loan balance, or Demand Note. The Demand Note is
capped at $23.0 million and the terms of our September 2004 credit facility cap the note at such amount. The Demand Note bears interest at a rate equal to the rate of interest on our credit facility, which was 5.25% at March 31, 2005. American
BioScience is required to repay any amounts outstanding under the Demand Note by the earlier of November 20, 2006 or our cumulative payment of $75.0 million of profit on ABRAXANE to American BioScience under the license agreement. As security for American BioSciences obligations under the
Demand Note, American BioScience pledged and granted to us a security interest in shares of our common stock held by American BioScience having a fair market value equal to 120% of the balance of the Demand Note.



American Pharmaceutical Partners charges incurred on American BioSciences behalf
related to labor and other costs directly associated with ABRAXANE product development, income taxes, interest and an agreed allocation of administrative costs to the American BioScience loan account. A summary of activity in the amounts due from American BioScience, which is
classified as a reduction of stockholders equity in the accompanying consolidated balance sheets, follows:

Inventories consist of products
currently approved for marketing and may include certain products pending regulatory approval. From time to time, we capitalize inventory costs associated with products prior to regulatory approval based on our judgment of probable future commercial
success and realizable value. Such judgment incorporates our knowledge and best judgment of where the product is in the regulatory review process, our required investment in the product, market conditions, competing products and our

##### Table of Contents

economic expectations for the product postapproval relative to the risk of manufacturing the product prior to approval. If final regulatory approval for such
products is denied or delayed, we may need to expense such previously capitalized costs.



At March 31, 2005, raw materials included $18.4 million in inventory relating to generic products pending ANDA approval, one approval of which was received in April 2005. At December 31, 2004, our investment in
inventory pending regulatory approval consisted solely of ABRAXANE related inventory pending approval as of the financial statement date. Commercial shipments of ABRAXANE commenced on February 7, 2005.



We routinely review our inventory and establish reserves when the cost of the inventory is not expected to be recovered or our product cost exceeds realizable market
value. In instances where inventory is at or approaching expiry, is not expected to be saleable based on our quality and control standards or for which the selling price has fallen below cost, we reserve for any inventory impairment based on the
specific facts and circumstances. In evaluating the market value of inventory pending regulatory approval as compared to its cost, we consider the market, pricing and demand for competing products, our anticipated selling price for the product and
the position of the product in the regulatory review process. Provisions for inventory reserves are reflected in the financial statements as an element of cost of sales with inventories presented net of related reserves.

|(7) | Credit Facility
|--- | ---------------



On September 2, 2004, we entered into a $100 million three-year unsecured revolving credit and letter of credit facility, which may be extended to $150 million at our request. Debt acquisition fees of approximately
$0.4 million for the new facility are being amortized over the facilitys three-year term.



Interest rates under the credit facility vary depending on the type of loan made and our leverage ratio. The interest rate for Base Rate Loans is the greater of the prime rate charged by the lead bank, or the federal
funds rate plus 0.5%, less an Applicable Margin ranging from minus 50 basis points to zero, depending on our leverage ratio. At March 31, 2005, the interest rate for Base Rate Loans under the credit facility was 5.25%. The credit
facility limits the amount of and assesses a 0.125% fee on the face amount of outstanding letters of credit. With respect to the capital stock held by American BioScience, the credit facility prohibits us from declaring or paying any cash dividends
or making any other such cash distributions. Additionally, the terms of the credit facility limit the principal amount of the demand note received from American BioScience to $23.0 million, among various other covenants and restrictions. There were
no outstanding balances or letters of credit under the credit facility, and we were in compliance with all covenants, at March 31, 2005.



No interest expense was capitalized during the three-month periods ended March 31, 2005 or 2004.

|(9) | Litigation
|--- | ----------



We are from time to time subject to claims and litigation arising in ordinary courses of business. These claims have included assertions that our products infringe existing patents and also claims that the use of our
products has caused personal injuries. We intend to defend vigorously any such litigation that may arise under all defenses that would be available to us. In the opinion of management, the ultimate outcome of proceedings of which management is
aware, even if adverse to us, will not have a material adverse effect on our consolidated financial position or results of operations.

|(11) | Acquisition of Assets
|---- | ---------------------



On July 28, 2004, we acquired certain assets, including a 25,000 square foot manufacturing facility and certain injectable oncology product rights for a purchase price of
approximately $11 million in cash, subject to final adjustment. Located in Barbengo, Switzerland, the FDA approved facility uses Isolator Technology which is particularly suitable for the manufacture of oncolytic products, including daunorubicin,
methotrexate, and leucovorin calcium, for our U.S. operations. We have, and continue to, invest in both personnel and systems to enhance quality standards. We believe that the facility will be validated and begin operation mid-2005. Additionally, we
acquired eight FDA approved ANDAs covering 15 product codes and one ANDA pending with the U.S. FDA in the transaction which also included a number of generic injectable oncology products currently marketed in Europe and South America and a number of
Marketing Authorization Applications, or MAAs, currently approved or pending with the European Agency for the Evaluation of Medicinal Products.

Background



We are a pharmaceutical
company that develops, manufactures and markets injectable pharmaceutical products. We believe that we are the only independent U.S. public company with a primary focus on the injectable oncology, anti-infective and critical care markets, and we
further believe that we offer one of the most comprehensive injectable product portfolios in the pharmaceutical industry. We manufacture products in each of the three basic forms in which injectable products are sold: liquid, powder and lyophilized,
or freeze-dried.



We hold the exclusive North American right to sell
ABRAXANE, a proprietary nanoparticle injectable
oncology product that is a patented formulation of paclitaxel. Paclitaxel is the active ingredient in Taxol®, one of the worlds top selling cancer drugs. ABRAXANE was approved by the U.S. Food and Drug Administration, or FDA, in January 2005 and was launched on February 7, 2005.



Our core generic injectable products are generally used in hospitals, long-term care facilities, alternate care sites and clinics within North America. Unlike the retail
pharmacy market for oral products, the injectable pharmaceuticals marketplace is largely made up of end users who have relationships with group purchasing organizations, or GPOs, and/or specialty distributors who distribute products within a
particular end-user market, such as oncology clinics. GPOs and specialty distributors generally enter into collective product purchasing agreements with pharmaceutical suppliers in an effort to secure more favorable drug pricing on behalf of their
members.



We began in 1996 with an initial focus on U.S. marketing and
distribution of generic pharmaceutical products manufactured by others. In June 1998, we acquired Fujisawa USA, Inc.s generic injectable pharmaceutical business including manufacturing facilities in Melrose Park, Illinois and Grand Island, New
York and our research and development facility in Melrose Park, Illinois. We also acquired additional assets in this transaction, including inventories, plant and equipment and abbreviated new drug applications that were approved by or pending with
the U.S. Food and Drug Administration, or FDA.



We are a Delaware corporation
that was formed in 2001 as successor to a California corporation formed in 1996. We are a majority owned subsidiary of American BioScience, Inc., a California corporation. At March 31, 2005, American BioScience owned 47,984,160 shares, or 67.2%, of
our outstanding common stock.

Strategy



Our goal is to expand upon our position as an industry leader in the development, manufacture, sale and distribution of injectable pharmaceutical products, with an intent
on offering a broad portfolio of injectable products affecting every aspect of hospital care. Key elements of our strategy include:



| |  |  | quickly develop the market for our new proprietary oncology product, ABRAXANE, via strong marketing and educational programs, introduction into other licensed North American markets and further clinical pursuit of the use of
ABRAXANE in other indications and treatment
regimens;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | continued focus on other new, higher-margin injectable product opportunities, including: complementary proprietary products; generic opportunities as products approach patent
expiry; low molecular weight heparins; and, as the FDA regulatory environment evolves, generic biological products;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | maintaining and improving our current Good Manufacturing Practice, or cGMP, product development and manufacturing capabilities and creating capacity to meet future market needs and
evolving regulatory requirements;

1stQuarter 2005 Highlights



The FDA approved ABRAXANE, our licensed oncology product, for the filed indication on January 7, 2005 and ABRAXANE was launched on February 7, 2005. ABRAXANE, consists only of albumin-bound paclitaxel nanoparticles, is free of toxic solvents and demonstrated a superior response rate with an almost
doubling of the reconciled target lesion response rate when compared with the solvent-based Taxol®in a prospectively randomized Phase III trial of 460 patients with metastatic breast cancer.



Because it contains no toxic solvents, this next-generation taxane product enables the administration of 50% more chemotherapy with a well-tolerated safety profile, requires no routine premedication to prevent
hypersensitivity reactions and can be given over a shorter infusion time using standard IV tubing. To date, approximately 45 ABRAXANE clinical trials have been initiated or are planned in various settings including:



| |  |  | Twenty-two studies in breast cancer; 12 in early disease and 10 in advanced disease, including two recently initiated studies:
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | an ongoing Phase II study of ABRAXANETMadministered weekly in combination with Herceptin in the first-line treatment of metastatic breast cancer, and;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a Phase II study of dose dense ABRAXANE administered as adjuvant therapy following Adriamycin® plus Cytoxan® in early stage breast cancer which recently completed patient enrollment.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Eleven studies in non-small cell lung cancer.
| | - |  | ---------------------------------------------



| |  |  | Five studies in ovarian and cervical cancer.
| | - |  | --------------------------------------------



| |  |  | Five studies in prostate cancer.
| | - |  | --------------------------------



| |  |  | A study in head and neck cancer.
| | - |  | --------------------------------



| |  |  | A study in melanoma.
| | - |  | --------------------



To date in 2005, we have obtained four FDA Abbreviated New Drug Application (ANDA) approvals. We currently have 19 ANDAs on file and under review at the FDA and over 50 potential ANDA applications under
development.

2005 Outlook



With respect to the remainder of 2005, we provide the following guidance:



| |  |  | net sales growth in the core generic injectable business is expected to be in the mid-teens range, the majority of such growth projected for the latter half of the year reflecting
the timing of product launches;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | ABRAXANE 2005 net sales are expected in the range of $125 million to $155 million;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | gross margin, after any ABRAXANE profit sharing, is anticipated to be in the high 50 percent range relative to net sales;
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | expenses related to ABRAXANE, which totaled $13.3 million in the 2005 first quarter, are expected to approximate $65-$70 million for all of 2005, primarily reflecting the cost of ongoing launch activities and the
expansion of manufacturing capabilities;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | operating expenses, excluding ABRAXANE related expense, depreciation and amortization, are anticipated to increase in line with core sales volumes.

Net Sales



Net sales in the 2005 first quarter increased $31.5
million, or 35%, to $120.7 million as compared to the same 2004 quarter. For the same periods, oncolytic net sales increased $25.9 million with the February launch of ABRAXANE contributing $34.8 million in sales, partially offset by softer demand for pamidronate and other more mature oncolytic
products, due in part to reimbursement changes effective January 1, 2005. First-quarter 2005 anti-infective net sales increased $11.8 million, or 41%, in 2005 driven by sales of recently launched antibiotics including bacitracin and tobramycin, and
good demand and stable

pricing for our more mature antibiotic products, largely offset by a raw material supply disruption. First-quarter 2005, critical care net sales fell $4.6
million, or 12%, as compared to the same 2004 quarter due primarily to the maturation of key critical care products. Oncolytic and anti-infective lines were each impacted by raw material and supply disruption, including from our recently acquired
Swiss facility.



Gross Profit



As compared to the 2004 first quarter, gross profit increased $30.9 million,
or 70%, due primarily to the February launch of our proprietary oncology product, ABRAXANE, partially offset by lower volume, but increased pricing in the core business. Gross profit represented 62.4% of sales in the 2005 quarter, 52.8% excluding ABRAXANE, as compared to 49.8% of sales in the first quarter of
2004.



Research and development (R&D)



First-quarter 2005 R&D expense declined $1.3 million,
or 18%, as compared to the 2004 first quarter due primarily to the timing of generic development work and temporarily reduced ABRAXANE  post-approval production development activity, partially offset by costs related to development of production capabilities at the new Swiss facility.



Selling, general and administrative (SG&A)



As compared to the 2004 first quarter, SG&A expense
increased $12.1 million, or 65%, in the 2005 first quarter due primarily to a $7.7 million increase in direct ABRAXANE sales and marketing costs. The remaining increase was attributable to higher depreciation expense associated with a new IT system and increased
professional service and staffing requirements resulting from continued infrastructure enhancement.



Other Expenses



Drug Source Company, LLC, is a 50% owned company, and is a selling agent of raw material to the pharmaceutical industry, including us. Our investment in
Drug Source Company is intended to both generate a return on our investment and to strengthen our strategic sourcing capabilities over time. Because our 50% ownership interest in Drug Source Company does not provide financial or operational control
of Drug Source Company, we account for our interest in Drug Source Company under the equity method. Our first-quarter equity income in Drug Source Company was $0.5 million in each of the 2005 and 2004 first quarters. Research and development expense
included raw material purchases from Drug Source Company of $0.7 million and $0.3 million in the 2005 and 2004 first quarters, respectively. Ending inventory included raw material purchases from Drug Source Company of $5.2 million and $2.9 million
at March 31, 2005 and December 31, 2004, respectively.



Interest income consists primarily of interest earned on the intercompany note from American BioScience and interest earned on invested cash, and was comparable between the 2005 and 2004 first quarters. Interest expense and other consists
primarily of miscellaneous interest expense and other financing costs. The first-quarter 2004 credit resulted primarily from foreign exchange gains on our intercompany trading account with our wholly owned Canadian subsidiary, Pharmaceutical
Partners of Canada.



Provision for income taxes



Our effective income tax rate in the 2005 first quarter
was 38.0%, comparable to the 38.8% rate in the prior year quarter.

We believe that our
current cash and short-term investments, cash generated from operations, funds available under our revolving line of credit and the potential ability to issue debt or equity securities under our shelf registration will be sufficient to finance our
operations, including ongoing launch activity relating to ABRAXANE, product development and capital expenditures for at least the next 12 months. In the event we engage in future acquisitions we may have to raise additional capital through additional borrowings or the issuance of debt
or equity securities or otherwise.



Capital
Requirements



Our capital requirements depend on numerous
factors, including:



| |  |  | working capital requirements and production, sales, marketing and development costs required to support our newly launched proprietary oncology product, ABRAXANE;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the need for manufacturing expansion and improvement;
| | - |  | -----------------------------------------------------



| |  |  | the requirements of any potential future, acquisitions, asset purchases or equity investments;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | the amount of cash generated by operations.
| | - |  | -------------------------------------------



We presently anticipate that our 2005 capital expenditure requirements will approximate $60 million.



Adequate funds for these and other purposes may not be available when needed
or on terms acceptable to us, and we may need to raise capital that may not be available on terms favorable or acceptable to us, if at all. Any additional equity financing may be dilutive to stockholders, and debt financing, if available, may
include restrictive or undesirable covenants and costs. If we cannot raise money when needed, we may have to reduce or slow ABRAXANE activity, reduce capital expenditures or scale back development of new products.

Sources of Financing



In addition to available cash on hand and cash flow from operations, we have additional financing available under our
unsecured, three-year $100 million credit facility established in September 2004. The facility can be increased to $150 million at our option. There were no balances outstanding under our credit facility and we were in compliance with all covenants
at March 31, 2005.



Sources and Uses of Cash



Operating Activities



Cash flow from operations is our primary source of liquidity, totaling $47.2
million and $57.5 million in the 2004 and 2003 fiscal years, respectively. In the first three months of 2005, net cash used for operating activities was $2.7 million as compared to a net use of $0.2 million in the 2004 first quarter. The 2005 first
quarter increase in cash used in operations was due primarily to ABRAXANE working capital requirements; including a $34.8 million increase in ABRAXANE related accounts receivable and an $11.8 million increase in ABRAXANE inventory, primarily finished goods and work in process. Total inventory increased $28.8 million, attributable to the $11.8 million ABRAXANE increase and a $17.3 million increase in inventory
related to recently, and soon-to-launch generic products; partially financed by a $7.5 million increase in accounts payable. Additionally, working capital benefited from an $11.4 million increase in accrued expenses, resulting primarily from
increased income and payroll withholding taxes payable.



Investing Activities



Our investing activities
consist principally of capital expenditures necessary to expand and maintain our manufacturing capabilities and infrastructure and outlays necessary to acquire various product or intellectual property rights. Also included in investing activities in
the 2005 and 2004 first quarters were sources of $35.7 million and $14.9 million in the 2005 and 2004 first quarters, respectively, related to our net sale of short-term investments. Our short-term investments consist of liquid, available-for-sale,
municipal variable rate demand notes, which are recorded at cost, and may generally be redeemed upon short notice. Net cash used for the acquisition of property, plant and equipment totaled $8.3 million and $5.5 million in the first three months of
2005 and 2004, respectively, the increase due primarily to increased investment in our core manufacturing and development capabilities. In the 2005 first quarter, purchase of product license rights included a $15.0 million license payment to
American BioScience resulting from the FDAs January 2005 approval of ABRAXANE. The $15.0 million ABRAXANE milestone payment has been capitalized and is being amortized over seven years.



Financing Activities



Financing activities generally include cash flows from the issuance or repurchase of our common stock, proceeds from the exercise of employee stock
options and transactions with American BioScience, our parent company. Net cash provided by financing activities totaled $5.4 million in the first quarter of 2005 as compared to $1.8 million in the 2004 first quarter and in each period consisted
primarily of cash proceeds from the exercise of employee stock options and sale of stock through the employee stock purchase program.

ABRAXANE LICENSE AND MANUFACTURING AGREEMENT



We hold the exclusive North American marketing rights and the worldwide manufacturing rights for ABRAXANE. The FDA approved ABRAXANE for the filed indication on January 7, 2005 and ABRAXANE was launched on February 7, 2005. ABRAXANE is licensed from American BioScience, which is responsible for conducting the
clinical studies of and obtaining regulatory approval for ABRAXANE.



In November 2001, we signed a perpetual
license agreement with American BioScience under which we acquired the exclusive rights to market and sell ABRAXANE in North America for indications relating to breast, lung, ovarian, prostate and other cancers. Under the agreement, we made an initial payment to
American BioScience of $60.0 million and committed to profit sharing and future milestone payments contingent upon achievement of specified regulatory, publication and sales objectives for licensed indications. American BioScience is responsible for
conducting clinical studies in support of ABRAXANE and for substantially all costs associated with the development and obtaining regulatory approval for ABRAXANE, except that we provided $2.0 million of ABRAXANE for use in clinical trials, the cost of which we charged to research and development expense in 2001.



Under the license agreement, profit on our sales of ABRAXANE North America will be shared equally between American BioScience and us. The
license agreement defines profit as ABRAXANE net
sales less cost of goods sold, selling expenses (including accumulated pre-launch production and other expenses which we have expensed as incurred, but which will be charged against first profit under the agreement) and an allocation of related
general and administrative expenses. At December 31, 2004, accumulated ABRAXANE expenses, which are being offset against future ABRAXANE profit sharing, totaled $49.1 million. We anticipate that ABRAXANE profit, as defined in the license agreement, will exceed this accumulated expense in late 2005, at which point we will begin expensing American BioSciences share of any profit
earned in our statements of income as an element of cost of sales. Any costs and expenses related to product recalls and product liability claims generally will be split equally between American BioScience and us and expensed as incurred.



Under the license agreement, American BioScience earned milestone payments
upon the filing and approval of ABRAXANE for the
metastatic breast cancer indication. The first such milestone of $10.0 million was achieved in May 2004 when the FDA accepted American BioSciences NDA for the metastatic breast cancer indication. This payment was expensed and paid in the
second quarter of 2004. The FDA then approved ABRAXANE for the filed indication in January 2005, triggering a $15.0 million milestone payment in the first quarter of 2005, which has been capitalized and is being amortized over seven years.



Regulatory or publication achievements related to other licensed indications under study,
including lung, ovarian and prostate cancers, will trigger further milestone payments to American BioScience. Such payments generally total $17.5 million per agreed indication. As with the indication for breast cancer, those payments earned prior to
FDA approval for each indication will be expensed, while amounts earned upon FDA approval of those indications will be capitalized and amortized over the expected life of the product. We have the option not to make one or more of the milestone
payments tied to certain indications under study if sales of the product do not meet specified levels.



Upon achievement of major annual one-time ABRAXANE sales milestones, we are required to make additional payments which, in the aggregate, could total $110.0 million should annual ABRAXANE sales exceed $1.0 billion. The first sales milestone payment of $10.0 million would be triggered upon achievement of
annual calendar year ABRAXANE sales in excess of
$200.0 million and the second sales milestone of $20.0 million upon the achievement of annual calendar year sales in excess of $400.0 million. Any future sales-based milestone payments will be expensed in the period in which the sales milestone is
achieved.



The terms of the license agreement were negotiated to reflect the
value of the licensed product rights acquired, then in late-stage development, American BioSciences remaining obligation to complete the NDA filing and the potential sales of the product under licensed clinical indications. The license
agreement was a product of several months of extensive negotiation with American BioScience involving outside counsel, investment banks and a nationally recognized valuation firm. Based upon the analysis and



21

##### Table of Contents

recommendations of our advisors, we believe that the overall terms of the agreement were fair to us, including in comparison to similar licenses between
unrelated parties. The agreement was unanimously approved by the disinterested members of our Board of Directors, with those directors who also have an affiliation with American BioScience recusing themselves from the vote. There are no restrictions
on how American BioScience would use payments made under the license agreement and we understand such payments have been and will be used both to fund the development of ABRAXANE in relation to our licensed product rights and for other purposes.



In December 2001, in conjunction with our initial public offering, we recorded an initial
payment due American BioScience of $60.0 million. In our financial statements, the license agreement was accounted for as an asset contributed by a principal shareholder using the shareholders historical cost basis, which was zero, and the
$60.0 million payment was accounted for as a distribution of stockholders equity. For income tax purposes, the payment was recorded as an asset and is being amortized over a 15-year period. Because there was no corresponding charge to income,
the income tax benefit of this payment is being credited to stockholders equity as realized.



In November 2001, along with the license agreement for ABRAXANE, we also entered into a manufacturing agreement with American BioScience under which we agreed to manufacture ABRAXANE for American BioScience and its licensees for sales outside North America. Under this
agreement, we have the right to manufacture ABRAXANE worldwide. For sales outside of our licensed territories, we will charge American BioScience and its licensees a customary margin on our manufacturing costs based on whether the product will be used for clinical trials
or commercial sale. The initial term of this agreement is ten years and may be extended for successive two-year terms by American BioScience.



CRITICAL ACCOUNTING POLICIES AND ESTIMATES



The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make
estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting
period. The most significant estimates in our consolidated financial statements are discussed below. Actual results could vary from those estimates.



Revenue recognition



We recognize revenue from the sale of a product when title and risk of loss have transferred to the customer, collection is reasonably assured and we have
no further performance obligation. This is typically when the product is received by the customer. At the time of sale, as further described below, we reduce sales and provide for estimated chargebacks, contractual allowances or customer rebates,
product returns and customer credits and cash discounts. Our methodology used to estimate and provide for theses sales provisions was consistent across all periods presented. Historically, Medicaid rebates issued have not been material; however we
anticipate and have provided for, an increase in Medicaid rebates as a result of the launch of ABRAXANE. Accruals for sales provisions are presented in our financial statements as a reduction of net revenue and accounts receivable and, for contractual allowances, an increase in accrued
liabilities. We regularly review information related to these estimates and adjust our reserves accordingly if, and when, actual experience differs from estimates.



We have extensive, internal historical information on chargebacks, rebates and customer returns and credits which we use as
the primary factor in determining the related reserve requirements. As further described below, due to the nature of our generic injectable products and their primary use in hospital and clinical settings with generally consistent demand, we believe
that this internal historical data, in conjunction with periodic review of available third-party data (as described below) and updated for any applicable changes in available information provides a reliable basis for such estimates. Additionally, we
periodically purchase external data on wholesale inventory levels from our wholesale customers, pharmaceutical sales data from third-party market research organizations and our sales force regularly visits wholesale locations to review
inventory-stocking levels.

##### Table of Contents

Sales to our three major wholesale customers comprised 89% of our 2004 net sales. We periodically review
the wholesale supply levels of our significant products by reviewing inventory reports purchased or available from wholesalers, evaluating our unit sales volume, and incorporating data from third-party market research firms and periodic visits to
wholesalers warehouses. Based on these activities, we attempt to keep a consistent wholesale stocking level of approximately two- to six-weeks across our generic products. The buying patterns of our customers do vary from time to time, both
from customer to customer and product to product, but we believe that historic wholesale stocking or speculative buying activity in our generic distribution channel has not had a significant impact on our historic sales comparisons or sales
provisions. To date we have not entered into any inventory management agreements with any of our wholesale customers which would require us to pay a fee in connection with their distribution of our products or other services, possibly including
sales data and other services and contractual rights for us, but we may be required to enter into such agreements in the future in order to maintain our relationships with such wholesalers. We are unable to ascertain the potential impact of any such
agreements on our cost of sales, but do not believe that such agreements would result in a substantial change in wholesale stocking levels of our products as compared to current levels.



Our sales provisions totaled $132.2 million and $212.1 million in the first quarters of 2005 and 2004, respectively, and
related reserves totaled $94.2 million and $124.4 million at March 31, 2005 and December 31, 2004, respectively.



Chargebacks



Following industry practice, we typically sell our products to independent pharmaceutical wholesalers at wholesale list price. The wholesaler in turn
sells our products to an end user, normally a hospital or alternative healthcare facility, at a lower contractual price previously established between us and the end user via a group purchasing organization, or GPO. GPOs enter into collective
purchasing contracts with pharmaceutical suppliers to secure more favorable product pricing on behalf of their end-user members.



Our initial sale to the wholesaler, and the resulting receivable, are recorded at our wholesale list price. However, as most of these selling prices will
be reduced to a lower end-user contract price, at the time of sale revenue is reduced by, and a provision recorded for, the difference between the list price and estimated end-user contract price multiplied by the estimated wholesale units
outstanding pending chargeback that will ultimately be sold under end-user contracts. When the wholesaler ultimately sells the product to the end user at the end-user contract price, the wholesaler charges us, a chargeback, for the difference
between the list price and the end-user contract price and such chargeback is offset against our initial estimated contra asset. The most significant estimates inherent in the initial chargeback provision relate to wholesale units pending chargeback
and the ultimate end-user contract-selling price. We base our estimation for these factors primarily on internal, product-specific sales and chargeback processing experience, estimated wholesaler inventory stocking levels, current contract pricing
and our expectation for future contract pricing changes.

net chargeback reserve totaled $55.0 million and $97.4 million at March 31, 2005 and December 31, 2004, respectively. The $42.4 million decrease in chargeback requirements during 2005 first quarter resulted from a $36.7 million decrease in sales of
generic products and an increase proportion of sales late in the fourth quarter requiring a chargeback reserve at December 31, 2004, as compared to the timing of first quarter 2005 sales. As a proprietary product, ABRAXANE does not require significant chargeback reserves. The
methodology we used to estimate and provide for chargebacks was consistent across all periods presented. Due to information constraints in the distribution channel, it has not been practical, and has not been necessary, for us to capture and
quantify the impact of current versus prior year activity on the chargeback provision. We do review current year chargeback activity to determine whether material changes in the provision relate to prior period sales; such changes have not been
material. A one-percent decrease in our estimated end-user contract-selling prices would reduce first-quarter 2005 net sales by $0.7 million and a one-percent increase in wholesale units pending chargeback at March 31, 2005 would decrease 2005
first-quarter net sales by $0.4 million.

Contractual allowances, returns and credits, cash discounts and bad debts



Contractual allowances, generally rebates or administrative fees, are
offered to certain wholesale customers, GPOs and end-user customers, consistent with pharmaceutical industry practices. Settlement of rebates and fees may generally occur from one to 15 months from date of sale. We provide a general provision for
contractual allowances at the time of sale based on the historical relationship between sales and such allowances. Upon receipt of chargeback, due to the availability of product and customer specific information on these programs, we then establish
a specific provision for fees or rebates based on the specific terms of each agreement. Our reserve for contractual allowances totaled $16.3 million at March 31, 2005 and $11.4 million at December 31, 2004. A one-percent increase in the estimated
rate of contractual allowances to sales at March 31, 2005 would increase the provision for contractual allowances by $1.4 million at that point in time. Contractual allowances are reflected in the financial statements as a reduction of net sales and
as a current accrued liability.



Consistent with industry
practice, our return policy permits our customers to return products within a window of time before and after the expiration of product dating. We provide for product returns and other customer credits at the time of sale by applying historical
experience factors generally based on our historic data on credits issued by credit category or product, relative to related sales and we provide specifically for known outstanding returns and credits. Our reserve for customer credits and product
returns totaled $9.7 million and $9.4 million at March 31, 2005 and December 31, 2004, respectively. At March 31, 2005, a one percent increase in the estimated reserve requirements for customer credits and product returns would have decreased
first-quarter 2005 net sales by $1.0 million.



We generally
offer our customers a standard cash discount for prompt payments and, from time-to-time, may offer a greater discount and extended terms in support of product launches or other promotional programs. Our wholesale customers typically pay within terms
and a provision for cash discount is established at the time of sale based on the terms of sale.



We establish a reserve for bad debts based on general and identified customer credit exposure. Our historic bad debt losses have been insignificant.



Inventories



Inventories consist of products currently approved for marketing and may
include certain products pending regulatory approval. From time to time, we capitalize inventory costs associated with products prior to regulatory approval based on our judgment of probable future commercial success and realizable value. Such
judgment incorporates our knowledge and best judgment of where the product is in the regulatory review process, our required investment in the product, market conditions, competing products and our economic expectations for the product post approval
relative to the risk of manufacturing the product prior to approval. If final regulatory approval for such products is denied or delayed, we may need to expense such previously capitalized costs.



At March 31, 2005, raw materials included $18.4 million in inventory relating
to generic products pending ANDA approval, one approval of which was received in April 2005. At December 31, 2004, our investment in inventory pending regulatory approval consisted solely of ABRAXANE related inventory pending approval as of the financial statement date. Commercial
shipments of ABRAXANE commenced on February 7,
2005.



We routinely review our inventory and establish reserves
when the cost of the inventory is not expected to be recovered or our product cost exceeds realizable market value. In instances where inventory is at or approaching expiry, is not expected to be saleable based on our quality and control standards
or for which the selling price has fallen below cost, we reserve for any inventory impairment based on the specific facts and circumstances. In evaluating the market value of inventory pending regulatory approval as compared to its cost, we consider
the market, pricing and demand for competing products, our anticipated selling price for the product and the position of the product in the regulatory review process. Provisions for inventory reserves are reflected in the financial statements as an
element of cost of sales with inventories presented net of related reserves.

Expense recognition



Cost of sales represents the costs of the products which we have sold and consists of labor, raw materials, components,
packaging, quality assurance and quality control, shipping and manufacturing overhead costs and the cost of finished products purchased from third parties.



Research and development costs are expensed as incurred or consumed and consist primarily of salaries and other personnel-related expenses, as well as
depreciation of equipment, allocable facility, raw material and production expenses and contract and consulting fees. We have invested and will continue to invest in research and development to expand our new product offerings, enhance our
manufacturing capabilities and grow our business.



Selling,
general and administrative expenses consist primarily of salaries, commissions and other personnel-related expenses, as well as costs for travel, trade shows and conventions, promotional material and catalogs, advertising and promotion, facilities,
risk management and professional fees. We believe that our selling, general and administrative expenses will continue to increase in line with the growth of our core generic and proprietary business.



Stock-based compensation



Stock-based compensation related to research and development costs and
selling, general and administrative expenses are presented separately in our consolidated statements of operations. Stock-based compensation represents the difference between the exercise price of options granted and the deemed fair value of our
common stock on the grant date in accordance with Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, and its related interpretations. We recognize stock-based compensation over the option vesting period,
typically four years, primarily on an accelerated basis using the graded vesting method in accordance with Financial Accounting Standards Board Interpretation No. 28, Accounting for Stock Appreciation



We have recorded deferred stock-based compensation related to stock options
granted to employees and outside directors with such expense related to the issuance of stock based compensation which was either performance-based or, prior to the date of our initial public offering, for which the exercise price was less than the
estimated fair value of common stock on the grant date.



RECENT ACCOUNTING
PRONOUNCEMENTS



On December 16, 2004, the Financial
Accounting Standards Board issued Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment, or SFAS 123(R). SFAS 123(R) supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees, and amends
Statement No. 95, Statement of Cash Flows. Generally, SFAS 123(R) requires all share-based payments to employees to be recognized in the income statement based on their estimated fair value at date of grant amortized over the grants
vesting period. Pro forma disclosure of such estimated fair value is no longer an alternative financial statement presentation.



SFAS 123(R) is now effective for fiscal years beginning after June 15, 2005 and offers two alternate means of adoption, either: the modified
prospective method in which compensation cost is recognized for awards granted after the effective date of the statement and outstanding, unvested awards granted prior to SFAS 123(R)s effective date, or; a modified
retrospective method which applies the modified prospective method, but allows companies to restate prior periods based on amounts calculated for pro forma disclosures under the original Statement 123 for either all prior periods presented or
prior interim periods in the year of adoption.



We plan to
adopt SFAS 123(R) in the first quarter of 2006 but have not yet determined which transition option we will apply. The adoption of SFAS 123(R) will significantly impact our results of operations, but will have no impact on our overall financial
position. The impact of SFAS 123(R) on our results of operations cannot be accurately predicted at this time, as it will depend on future market prices and equity grants. However, had we adopted SFAS 123(R) in prior periods, the impact of the
standard on the past period would likely approximate the pro forma amounts calculated and disclosed under the

##### Table of Contents

original Statement 123. SFAS 123(R) also requires that the any tax benefit in excess of compensation cost, as calculated under the new standard, be reported
in the statement of cash flows as a financing activity rather than an operating activity. This change will reduce reported net operating cash flow and will equally increase reported net financing cash flow in periods after adoption. While we cannot
estimate what those amounts will be in the future, the amount of operating cash flows recognized in prior periods for such excess tax deductions were $2.9 million, $5.1 million, and $2.4 million in 2004, 2003 and 2002, respectively.



|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|------- | ----------------------------------------------------------



The primary objective of our investment activities is to preserve principal while at the same time maximizing the income we receive from our activities
without increasing risk. Some of the securities that we invest in may have interest rate risk. This means that a change in prevailing interest rates may cause the fair value of the principal amount of the investment to fluctuate. For example, if we
hold a security that was issued with a fixed interest rate at the prevailing rate and the prevailing rate later rises, the fair value of the principal amount of our investment will probably decline.



To minimize this risk, we intend to maintain an investment portfolio of cash
equivalents and short-term investments consisting of high credit quality securities, including commercial paper, government and non-government debt securities and money market funds. We do not use derivative financial instruments. The average
maturity of the debt securities in which we invest has been less than 90 days and the maximum maturity has been three months. Because our investments are diversified and are of a short-term nature, a hypothetical one or two percentage point change
in interest rates would not have a material effect on our consolidated financial statements.



We have operated primarily in the United States and the majority of our activities with our collaborators outside the United States to date have been conducted in U.S. dollars. Our more significant currency risks are
denominated in the Canadian and Australian dollars and Swiss Franc. We do not believe we have a material exposure to foreign currency risk because of the relative stability of these currencies in relation to the U.S. dollar. A 10% adverse change in
currency exchange rates of the Canadian or Australian dollars or Swiss Franc versus the U.S. dollar would not have a material effect on our consolidated results of operations, financial position, or cash flows. Accordingly, we have not had any
material exposure to foreign currency exchange rate fluctuations.

|ITEM 4. | CONTROLS AND PROCEDURES
|------- | -----------------------



(a)Evaluation of disclosure controls and procedures.



We have carried out an evaluation, under the supervision and with the participation of management, including our chief executive officer and our chief financial officer of the effectiveness of our internal disclosure controls and procedures
as of the end of the period covered by this report. Based on their evaluation, our chief executive officer and chief financial officer have concluded that our disclosure controls and procedures are designed to ensure that information required to be
disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms, and are functioning effectively to provide reasonable
assurance that we can meet our disclosure obligations. Consistent with the SECs recommendations to public companies, we have formed a disclosure committee consisting of key personnel designed to review the accuracy and completeness of all
disclosures made by us.



(b)Changes in internal controls.



In January 2004, we migrated our central data and operational processing
system to an SAP enterprise resource planning, or ERP, system designed for pharmaceutical manufacturers. In addition to expanding and improving our access to information, we believe that, over time, the new ERP system will yield operational
efficiencies, facilitate regulatory compliance and expand our customer service and fulfillment capabilities. As we grow, the new ERP system will also enable us to better control and maintain the integrity of our information systems by providing a
standard, central systems platform. There were no other significant changes in our internal controls or, to the knowledge of management, in other factors that could significantly affect internal controls subsequent to the date of the our most recent
evaluation of its disclosure controls and procedures utilized to compile information included in this filing.

PART II. OTHER INFORMATION



|ITEM 1. | LEGAL PROCEEDINGS
|------- | -----------------



We are from time
to time subject to claims and litigation arising in ordinary courses of business. These claims have included assertions that our products infringe existing patents and also claims that the use of our products has caused personal injuries. We intend
to defend vigorously any such litigation that may arise under all defenses that would be available to us. In the opinion of management, the ultimate outcome of proceedings of which management is aware, even if adverse to us, will not have a material
adverse effect on our consolidated financial position or results of operations.
