NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

QUARTER ENDED MARCH 31, 2005



NOTE 1  BASIS OF PRESENTATION



The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting
principles for interim financial reporting and in accordance with Form 10-Q and Rule 10.01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, the unaudited condensed consolidated financial statements contained in this report reflect all adjustments that are normal and recurring in nature and considered necessary for a fair presentation
of the financial position and the results of operations for the interim periods presented. The preparation of the Companys financial statements in conformity with generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as disclosures on contingent assets and liabilities. Because of inherent uncertainties in this process, actual future results could differ from
those expected at the reporting date. These unaudited condensed consolidated financial statements, footnote disclosures and other information should be read in conjunction with the financial statements and the notes thereto included in the
Companys Registration Statement on Form S-4, filed with the SEC December 17, 2004, as amended, and subsequent filings.



NOTE 2  THE MERGER TRANSACTION



On March 20, 2004, US Oncology Holdings, Inc. (Holdings) (formerly known as Oiler Holding Corp.) and its wholly owned
subsidiary, Oiler Acquisition Corp., entered into a merger agreement with US Oncology pursuant to which Oiler Acquisition Corp. was to be merged with and into US Oncology, with US Oncology continuing as the surviving corporation.



On August 20, 2004, the merger transaction was consummated, and US Oncology became a wholly
owned subsidiary of Holdings. The merger transaction was valued at approximately $1.6 billion. In the transaction, all of the former stockholders of US Oncology (other than Welsh, Carson, Anderson & Stowe IX, L.P. (WCAS), its
affiliates, and certain members of management and continuing shareholders) received $15.05 per share in cash for common stock of US Oncology. Holders of stock options issued by the Company received cash equal to (a) $15.05 minus the exercise price
of the option multiplied by (b) the number of shares subject to the options. Physicians who were entitled to receive shares of common stock at future dates as part of the consideration for affiliating with the Company received $15.05 per share of
such stock, in cash, at the time of the merger. After the merger, US Oncologys common stock withdrew its listing on the NASDAQ Stock Market, and US Oncology became a privately-held company. The merger and related transactions are referred to
in this report as the Merger or August Transactions.



The funds necessary to consummate the August Transactions were approximately $1,570.5 million, including approximately $1,185.0 million to pay the then current stockholders, option holders and holders of outstanding rights to receive shares
of US Oncology common stock pursuant to delayed share delivery agreements and all amounts due under the merger agreement, approximately $281.1 million to repay existing indebtedness and approximately $104.4 million to pay related fees of
approximately $50.1 million and expenses of approximately $54.3 million. Prior to the merger, 14,307,501 shares of US Oncology common stock then owned by WCAS and its affiliates, with a fair value of $215.3 million, were contributed to Holdings in
exchange for shares of the Companys common and participating preferred stock in Holdings. Upon consummation of the merger, those shares were cancelled without payment of any merger consideration.



The August Transactions were financed by:



| |  |  | a cash common and preferred equity investment in Holdings by WCAS and its related equity investors of $302.4 million, which funds were contributed to US Oncology;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the borrowing by US Oncology of $400.0 million in term loans under its new senior secured credit facility;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | $245.0 million of cash on hand at the closing date; and
| | - |  | -------------------------------------------------------



| |  |  | the issuance by US Oncology of $300.0 million aggregate principal amount of senior notes and $275.0 million aggregate principal amount of senior subordinated notes.

The August Transactions were accounted for under the purchase method of accounting prescribed in Statement of
Financial Accounting Standards No. 141, Business Combination, (SFAS No. 141), with intangible assets recorded in accordance with SFAS No. 142, Goodwill and Other Intangible Assets (SFAS No. 142). The purchase price, including
transaction-related fees, was allocated to the Companys tangible and identifiable intangible assets and liabilities based upon estimates of fair value, with the remainder allocated to goodwill.



The following table summarizes the preliminary allocation of the August Transactions as of
March 31, 2005 (in millions):



|                                                   |  |   |          |  
|-------------------------------------------------- |  | - | -------- | -
|Cash and equity contributed by WCAS and affiliates |  | $ | 517.8    |  
|Total liabilities assumed                          |  |   | 1,321.8  |  
|Fair value of assets acquired                      |  |   | (1,104.7 | )
|                                                   |  |   |          |  
|Excess purchase price (goodwill)                   |  | $ | 734.9    |  
|                                                   |  |   |          |  



While the Company continues to obtain
information to refine the fair values of the assets acquired and the liabilities assumed, the allocation of the purchase price is substantially complete as of March 31, 2005. As the Company completes its tax filings for the period ended with the
August Transactions, additional adjustments may be required to the deferred tax balances. Adjustments, if any, attributable to the tax returns for the period ended August 20, 2004 will be considered a result of the August Transactions and may result
in additional adjustments to the purchase price allocation and the amount of goodwill. In accordance with the provisions of SFAS No. 142, no amortization of indefinite-lived intangible assets or goodwill will be recorded. The Company expects that a
final allocation of the purchase price will be completed no later than June 30, 2005.



Subsequent to the initial capitalization of the Company, additional capital contributions of $40.0 million were received from Holdings. The contribution represents the proceeds from a private equity offering to certain affiliated physicians
and employees of the Company.



In connection with the August Transactions, the
Company incurred merger-related charges of $56.2 million. This amount includes loss on early extinguishment of debt of $38.3 million and merger-related expenses of $17.9 million. Included in merger related charges are legal costs of $3.8 million,
advisory fees of $6.0 million and other fees and expenses of $8.1 million. Merger-related charges, including early extinguishment of debt, amounted to $47.9 million for the Predecessor company compared to $8.3 million for the Successor company.



The carrying value of the Companys goodwill is subject to impairment
tests under the requirements of SFAS No. 142. Goodwill was allocated to each of the Companys reporting units based on their fair values at the date of the August Transactions. On an ongoing basis, the Company will perform impairment tests of
the goodwill by comparing the fair value of the reporting units discounted cash flows with their carrying values. The fair value is calculated using discounted cash flows, market multiples and market capitalization, as well as EBITDA analyses.
The Company expects to perform impairment tests on an ongoing basis at least annually, or more frequently with respect to assets for which there are any impairment indicators.



During the quarter ended March 31, 2005, Holdings, whose sole asset is its investment in US Oncology, Inc., issued $250,000,000 of Senior
Floating Rate Notes, due 2015 (the Notes). The Notes are senior unsecured obligations of Holdings and bear interest at a floating rate, reset semi-annually, equal to 6-month LIBOR plus 5.25 percent. Simultaneously with the financing,
Holdings entered into an interest rate swap arrangement, effectively fixing the interest rate at 9.4 percent for a period of two years. Because Holdings sole asset is its investment in US Oncology, the Company plans to provide funds sufficient
to service the indebtedness through the payment of dividends to Holdings.



Proceeds from the offering were used to pay a special dividend of $250 million to stockholders of Holdings. The payment of the special dividend triggered a payment obligation of $14.5 million under the Holdings long-term incentive plan, and
Holdings also incurred $7.2 million in expenses related to the offering. These amounts were financed with a dividend from US Oncology to Holdings and were paid in the second quarter of 2005.



Payment of interest expense on the new Holdings notes will be financed through the payment of
periodic dividends from the Company. During the period that the interest rate has been fixed, the expense will amount to

approximately $23.5 million per year, and may be more or less than that amount thereafter. Certain restrictions in US
Oncologys note indentures and certain other circumstances could prevent payment of such a dividend by US Oncology in the future, which could cause Holdings to default on its notes unless other sources of funding are available.



NOTE 3  REVENUE



The Company derives revenues primarily from (i) comprehensive service arrangements with
physician practices under the physician practice management (PPM) model; (ii) pharmaceutical services agreements with physician practices under the service line model; (iii) research agreements with pharmaceutical manufacturers and other
trial sponsors and (iv) fees paid by pharmaceutical companies for services as a group purchasing organization, data services and other services.



Under both PPM and service line agreements with physician practices, a portion of the Companys revenues is derived from sales of pharmaceutical products and a
portion of such revenues is derived from the provision of comprehensive practice management services. Physician practices that enter into comprehensive service agreements with the Company receive a broad range of services and receive pharmaceutical
products. These products and services represent multiple deliverables provided under a single contract, with a single fee. The Company has analyzed the component of the contract attributable to the provision of products (pharmaceuticals) and the
component of the contract attributable to the provision of services and attributed fair value to each component. For revenue recognition purposes, the product revenues and service revenues have each been accounted for as a separate unit of
accounting.



Product revenues consist of sales of pharmaceuticals to practices
in connection with the Companys comprehensive service agreements under the PPM model or under its pharmaceutical services service line. Under all arrangements with affiliated practices, the Company agrees to furnish the practice with
pharmaceuticals and supplies. In certain cases, it takes legal title to the pharmaceuticals and resells them to practices. In other cases, title to the pharmaceuticals passes directly from the Companys distributor to the practices under
arrangements negotiated and managed by the Company pursuant to its service agreements with the practices.



Because it acts as principal, the Company recognizes revenues equal to (a) the cost of the pharmaceutical (which is reimbursed pursuant to all of the Companys contractual arrangements with physician practices)
plus (b) an additional amount. Under the service line model, this additional amount is the actual amount charged to practices under the service line model because all of the services provided under the service line model are directly related to and
not separable from the delivery of the products. Under the PPM model, the contracts do not provide for a separate fee for supplying pharmaceuticals other than reimbursement of the cost of pharmaceuticals. Accordingly, the additional amount included
in product revenues reflects the Companys estimate of the portion of its service fee that represents fair value relative to product sales. The portion of the service fee allocated to product sales is based upon the terms upon which the Company
offers pharmaceutical services under its service line model. The Company provides the same services and products under the service line model as it does as part of its PPM arrangements. Accordingly, the Companys management believes this
allocation is appropriate. Discounts and rebates are deducted from product revenues and costs.



Service revenues consist of revenues other than product revenues under the Companys service agreements with affiliated practices.



For both product and service revenues under the PPM model, the Company recognizes revenues when the fees are earned and are deemed
realizable based upon the contractually agreed amount of such fees.



Under the
PPM model, the revenue recognized reflects two components of the fee: (i) specific reimbursements related to practice operations and (ii) and an additional fee based upon practice performance. In recognizing revenue, the Company takes into
consideration the priority of payments relating to amounts retained by practices. Under net revenue model agreements, the practice is entitled to retain a specific portion of revenues after reimbursement of expense reimbursements, but prior to
payment of any additional fee to us. The Company does not recognize revenue to the extent funds are not available to pay such fees as a result of such priority of payments. Net operating revenue of affiliated practices is reduced by amounts retained
by the practices under the Companys PPM service agreements to arrive at the amount reported as revenue in the Companys financial statements.

US Oncology, Inc

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

QUARTER ENDED MARCH 31, 2005 continued



Under the Companys pharmaceutical service line arrangements, revenue is recognized as drugs are accepted and
dispensed by the affiliated practices. The Company recognizes revenue based upon the cost of pharmaceuticals purchased by the affiliated practice plus a fee for pharmaceutical services. Such amounts are recorded in product revenues and the related
costs are included in cost of products. The Company recognizes revenue for admixture services as those services are performed.



Recognition of research revenues.Research revenue is derived from services provided to pharmaceutical companies and other trial sponsors and includes payments for
the initial activity to begin the research trial, patient enrollment and completion of the treatment cycle. Revenue is recognized as the Company performs its obligations related to such research and when the following conditions have been met: (i)
persuasive evidence of an arrangement exists, (ii) services have been rendered and (iii) collection of a fixed or determinable fee is considered reasonably assured.



Recognition of revenues as a group purchasing organization and revenues from providing services to pharmaceutical manufacturers and other
suppliers. The Company receives group purchasing organization (GPO) fees and other fees for providing services to pharmaceutical manufacturers and other suppliers. It recognizes revenue for these fees as it performs the services and when the
following conditions have been met: (i) persuasive evidence of an arrangement exists, (ii) services have been rendered and (iii) collection of a fixed or determinable fee is considered reasonably assured. Fees for GPO services and other services are
distinct from discounts and rebates and are paid to the Company for identifiable services provided to the drug vendor rather than in respect of drug purchases. The Company provides the vendor with, among other things, (1) data relating to, and
analysis of, pharmaceutical use by affiliated practices, (2) access to electronic order entry software from its pharmacy locations and physician practice sites, (3) contract management services and (4) other informational services.



For the three months ended March 31, 2004 and 2005, the affiliated practices derived
approximately 42% and 41%, respectively, of their net patient revenue from services provided under the Medicare program and approximately 3% from services provided under the state Medicaid programs. Capitation revenues were less than 1% of total net
patient revenue in both periods. Changes in the payor reimbursement rates, particularly Medicare and Medicaid, or affiliated practices payor mix can materially and adversely affect the Companys revenues.



Effective January 1, 2005, Medicare changed the way in which it reimburses providers for
oncology pharmaceuticals administered in physicians offices, including those in the US Oncology network. Medicare now pays oncologists the average sales price, or ASP, for the drug plus 6 percent. Previously, Medicare reimbursed physicians for
oncology pharmaceuticals based on average wholesale price, or AWP, which is significantly higher than ASP. During 2004, reimbursement for outpatient oncology drugs was generally 85 percent of AWP. This shift in reimbursement methodology represented
an approximately 15 percent reduction in the amount of reimbursement for oncology pharmaceuticals.



The Companys most significant and only service agreement to provide more than 10% of revenues is with Texas Oncology, P.A. (TOPA). TOPA accounted for approximately 25% of the Companys total revenues for
the first quarter of 2004 and 2005.



NOTE 4  SEGMENT
FINANCIAL INFORMATION



The Company has
adopted the provisions of FASB Statement of Financial Accounting Standards No. 131, Disclosure About Segments of an Enterprise and Related Information (SFAS 131). SFAS 131 requires the utilization of a management
approach to define and report the financial results of operating segments. The management approach defines operating segments along the lines used by management to assess performance and make operating and resource allocation decisions.



The Company has determined that its reportable segments are those that are
based on the Companys method of internal reporting, which disaggregates its business by service line. The Companys reportable segments are medical oncology services, cancer center services, and other services primarily consisting of
cancer research services. Under the medical oncology services segment, the Company purchases and manages specialty oncology pharmaceuticals and provides practice management services to medical oncology practices. Under the cancer center services
segment, the Company develops and manages comprehensive, community-based cancer centers, which integrate all aspects of outpatient cancer care, from laboratory and radiology diagnostic capabilities to chemotherapy

and radiation therapy. Under the other services segment, the Company contracts with pharmaceutical and biotechnology
firms to provide a comprehensive range of services relating to clinical trials. Results of operations for the medical oncology services segment and other services segment include arrangements under both the PPM and service line models. The Company
provides cancer center services only in PPM arrangements.



Balance sheet
information by reportable segment is not reported since the Company does not produce such information internally.



The table below presents information about reported segments for the quarters ended March 31, 2004 and 2005 (in thousands):

NOTE 5 - STOCK-BASED COMPENSATION



Predecessor Stock Incentive Plans



The following disclosures relate to the stock incentive plans of the Company prior to the
August Transactions. All such plans were terminated in connection with the August Transactions.



At March 31, 2004, the Company had eight stock-based employee compensation plans. The Company accounted for those plans under the recognition and measurement principles of Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees, and related interpretations. Stock based employee compensation costs for options granted under those plans with exercise prices less than the market value of the underlying Common Stock on the
date of the grant were insignificant for the three months ended March 31, 2004.



The following table illustrates the effect on net income if the Company had applied the fair value recognition provisions of FASB Statement No. 123, Accounting for Stock-Based Compensation, to stock-based employee compensation
(in thousands):

Successor Stock Incentive Plans



The following disclosures relate to the stock incentive plans of the
Company subsequent to the August Transactions.



Holdings, the Companys
parent, adopted the US Oncology Holdings, Inc. 2004 Equity Incentive Plan, which is referred to as the equity incentive plan. The equity incentive plan provides for grants of restricted stock and stock options of Holdings. The purpose of the equity
incentive plan is to attract and retain the best available personnel, provide additional incentives to the Companys employees and consultants and promote the success of its business. Because the plan is for the benefit of US Oncology, any
expenses related to awards under the plan are reflected in the Companys financial statements. Holdings granted 21,580,000 shares of common stock as restricted stock awards during the period from August 21 through December 31, 2004, and 240,000
shares during the quarter ended March 31, 2005. The fair value of the restricted stock awards of approximately $10.8 million and $0.4 million, respectively, was recorded as a component of Stockholders Equity, with a credit to Additional Paid
in Capital. Depending on the individual grants, awards vest either at the grant date, over defined service periods, or upon the Company achieving a return on invested capital in excess of established thresholds. Based on the individual vesting
criteria for each award, the Company recorded total amortization expense of approximately $1.0 million during the quarter ended March 31, 2005.



During October 2004, Holdings granted stock options for shares of common stock to certain employees and directors amounting to 1,820,000 options and through subsequent
awards and issuances 1,810,000 options were outstanding as of December 31, 2004. The options were granted at the fair value of Holdings common stock as of the date of grant, vest over 5 years and have an option term not to exceed 10 years. For the
quarter ended March 31, 2005 the Company awarded 445,000 options. As of March 31, 2005, 2,232,500 options are outstanding (net of forfeitures).



The Holdings Board of Directors also adopted the US Oncology Holdings 2004 Director Stock Option Plan, which became effective in October 2004 upon Holdings
stockholder approval. The total number of shares of common stock for which options may be granted under the plan is 500,000 shares. Under that plan, each eligible director in office at the plans adoption and each eligible director who joined
the board after adoption was automatically granted an option

QUARTER ENDED MARCH 31, 2005 continued



to purchase 5,000 shares of Holdings Common Stock. In addition, each such director was automatically granted an
option to purchase 1,000 shares of Holdings Common Stock for each board committee on which such director served. To date, under the 2004 Director Stock Option Plan, options to purchase 29,000 shares of Holdings Common Stock have been granted to
directors. In all cases, the exercise price for the options and the fair value are $1.00 per share, and the options vest six months after the date of grant.



The Company has elected to continue to follow APB 25, and the related interpretations in accounting for its employee stock options. Under APB 25, because the exercise
price of the Companys employee stock options is equal to or greater than the fair value of the underlying stock on the date of grant, no compensation expense is recognized. For the quarter ended March 31, 2005, if the Company had applied the
fair value recognition previsions of FASB No. 123, Accounting for Stock-Based Compensation, the related effects would have been immaterial to the Companys financial statements.



In addition to the 2004 Equity Incentive Plan, Holdings has adopted the US Oncology Holdings,
Inc. 2004 Long-Term Cash Incentive Plan, which is referred to as the Cash Incentive Plan. Under the Plan, which is administered by the Compensation Committee of the Board of Directors of Holdings, awards granted to participants provide for cash
payments upon a qualified initial public offering or change in control of Holdings, or upon dividends on or redemptions of preferred stock. Cash payments are payable to participants based upon certain performance objectives for the Company, as set
forth in the terms, conditions and other provisions of the awards under the Cash Incentive Plan. During the first quarter of 2005, Holdings declared and paid a special dividend of $250.0 million to its common and preferred stockholders. As a result
of the dividend paid to preferred stockholders, Holdings became obligated to make a cash payment of $14.5 million under the Cash Incentive Plan. The payment was financed through payment of a dividend by the Company to Holdings. Payment of the
dividend was made in the first quarter of 2005 and corresponding payment under the Cash Incentive Plan was made in the second quarter of 2005.



If any of the payment triggering events described in the Cash Incentive Plan should occur in the future, the additional obligation (and compensation expense) as a result
of such event or events would be approximately $18 million as of March 31, 2005. This amount may increase or decrease based upon future performance of the Company.



NOTE 6  INTANGIBLE ASSETS AND GOODWILL



The fair values of the identifiable intangibles acquired and the amount of goodwill recorded
as a result of the August Transactions were determined based on a valuation report by an independent third-party valuation firm. The Company continues to obtain additional information necessary to determine the fair value of assets acquired and the
amount of goodwill recorded as a result of the August Transactions. The allocation of the purchase price was substantially complete as of March 31, 2005. Although the allocation of the purchase price is subject to adjustment, management believes
that any adjustments will not be material in relation to the Companys Consolidated Financial Statements. As the Company completes its tax filings for the period ended with the August Transactions, additional adjustments may be required to the
deferred tax balances. Adjustments, if any, attributable to the tax returns for the period ended August 20, 2004 will be considered a result of the August Transactions and may result in additional adjustments to the purchase price allocation and the
amount of goodwill. The Company expects that a final allocation of the purchase price will be completed no later than June 30, 2005.

At the time of the August
Transactions, the basis for these intangible assets was adjusted to their fair values. Accumulated amortization relating to service agreements was $4.1 million and $7.2 million at December 31, 2004 and March 31, 2005, respectively.



The carrying value of goodwill is subject to impairment tests under the requirements of SFAS
No. 142. Goodwill was allocated to each of the Companys reporting units based on their fair values at the date of the August Transactions. On an ongoing basis, the Company will perform impairment tests of the goodwill by comparing the fair
value of the reporting units discounted cash flows with their carrying values. The fair value is calculated using discounted cash flows, market multiples and market capitalization, as well as EBITDA analyses. The Company performs impairment
tests on an ongoing basis annually, and more frequently in the event of any impairment indicators.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

QUARTER ENDED MARCH 31, 2005 continued



Summarized below are the principal terms of the agreements that govern the Companys outstanding indebtedness.



Senior Secured Credit Facility



The Companys senior secured credit facility provides for senior secured financing of
up to $560.0 million, consisting of:



| |  |  | a $160.0 million revolving credit facility, none of which was drawn as of March 31, 2005, including both a letter of credit sub-facility and a swingline loan sub-facility, that will
terminate in six years and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a $400.0 million term loan facility with a maturity of seven years that was drawn in full in connection with the consummation of the August Transactions. The amount outstanding
under the term loan was $383.1 million as of March 31, 2005.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Indebtedness under the senior secured credit facility is guaranteed by all of the Companys current restricted subsidiaries, all of the Companys future restricted subsidiaries and by Holdings and is secured by a first priority
security interest in substantially all of the Companys existing and future real and personal property, including accounts receivable, inventory, equipment, general intangibles, intellectual property, investment property, cash and a first
priority pledge of the Companys capital stock and the capital stock of the guarantor subsidiaries.



The senior secured credit facility requires the Company to comply on a quarterly basis with certain financial covenants, including an interest coverage ratio test and a maximum leverage ratio test, which financial
covenants will become more restrictive over time. In addition, the senior secured credit facility includes various negative covenants, including with respect to indebtedness, liens, investments, permitted businesses and transactions and other
matters, as well as certain customary representations and warranties, affirmative covenants and events of default, including payment defaults, breach of representations and warranties, covenant defaults, cross defaults to certain indebtedness,
certain events of bankruptcy, certain events under ERISA, material judgments, actual or asserted failure of any guaranty or security document supporting the senior secured credit facility to be in full force and effect and change of control. If such
an event of default occurs, the lenders under the senior secured credit facility are entitled to take various actions, including the acceleration of amounts due under the senior secured credit facility and all actions permitted to be taken by a
secured creditor. As of March 31, 2005, the Company is in compliance with all debt covenants.



Senior Notes and Senior Subordinated Notes



On August 20, 2004, Oiler Acquisition Corp. sold $300.0 million in aggregate principal amount of 9% senior notes due 2012 and $275.0 million in aggregate principal amount of 103/4% Senior Subordinated Notes due 2014 to Citigroup Global Markets Inc., J.P. Morgan Securities Inc., Wachovia
Capital Markets, LLC and Deutsche Bank Securities Inc., who are collectively referred to as the initial purchasers. Upon consummation of the August Transactions, these notes became obligations of the Company and are referred to herein as the senior
notes. The sale of the notes was exempt from registration under the Securities Act. The initial purchasers subsequently resold their notes to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to non-U.S. persons
outside the United States in reliance on Regulation S under the Securities Act. During the second quarter of 2005, the notes were exchanged for substantially identical notes in an offering registered under the Securities Act that was consummated on

The senior notes mature on August 15, 2012 and bear
interest at a rate of 9% per annum, payable semi-annually in arrears on February 15 and August 15, commencing on February 15, 2005. The senior notes are unconditionally guaranteed, jointly and severally and on an unsecured senior basis, by most of
the Companys subsidiaries. The senior subordinated notes mature on August 15, 2014 and bear interest at a rate of 103/4% per annum, payable semi-annually in arrears on February 15 and August 15, commencing on February 15, 2005. The senior subordinated notes are unconditionally guaranteed, jointly and severally and on
an unsecured senior subordinated basis, by most of the Companys subsidiaries.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

QUARTER ENDED MARCH 31, 2005 continued



Subordinated notes



The subordinated notes were issued in substantially the same form and are payable to the physicians with whom the Company entered into service agreements.
Substantially all of the notes outstanding at March 31, 2005 bear interest at 7%, are due in installments through 2007, and are subordinated to senior bank and certain other debt. If the Company fails to make payments under any of the notes, the
respective practice can terminate the related service agreement.



Mortgage,
capital lease obligations and other indebtedness



Leases for medical and
office equipment are capitalized using effective interest rates between 6.5% and 11.5% with original lease terms between two and seven years. Other indebtedness consists principally of mortgages, installment notes and bank debt, with varying
interest rates.



Holdings indebtedness



During the quarter ended March 31, 2005, Holdings, whose sole asset is its investment in US
Oncology, Inc., issued $250.0 million of Senior Floating Rate Notes, due 2015 (the Holdings Notes). The Holdings Notes are senior unsecured obligations of Holdings and bear interest at a floating rate, reset semi-annually, equal to
6-month LIBOR plus 5.25 percent. Simultaneously with the financing, Holdings entered into an interest rate swap arrangement, effectively fixing the interest rate at 9.4 percent for a period of two years. Because Holdings sole asset is its
investment in US Oncology, the Company plans to provide funds sufficient to service the indebtedness through the payment of dividends to Holdings.



Payment of interest expense on the new Holdings Notes will be financed through periodic dividends from US Oncology. During the period that the interest expense has been
fixed, the expense will amount to approximately $23.5 million per year, and may be more or less than that amount thereafter. Certain restrictions in US Oncologys note indentures and certain other restrictions could prevent payment of such
dividends by US Oncology in the future, which could cause Holdings to default on its notes unless other sources of funding are available.



Proceeds from the offering were used to pay a special dividend of $250 million to stockholders of Holdings in March 2005. The payment of the special dividend triggered a
payment obligation of $14.5 million under Holdings long-term incentive plan, and Holdings also incurred $7.2 million in expenses related to the offering. These amounts were financed with a dividend from US Oncology to US Oncology Holdings
declared during the first quarter of 2005 and paid in the second quarter of 2005.



Future principal obligations under the Companys and Holdings indebtedness as of March 31, 2005, are as follows (in thousands):

Leases



The Company leases office space, integrated cancer centers and certain equipment under noncancelable operating lease agreements. Total
future minimum lease payments, including escalation provisions and leases with entities affiliated with practices, are as follows (in thousands):

Pharmacy Distribution Initiative



During 2005, the Company commenced the acquisition of infrastructure and
systems for the development of a specialty distribution business for oncology pharmaceuticals. During the quarter ended March 31, 2005, the Company entered into a lease agreement with a 10-year term for a 75,000-square foot facility located in Ft.
Worth, Texas. The Company anticipates its specialty pharmacy distribution initiative in 2005 will require an investment of $15 million in systems, consultants and leasehold improvements. In addition, the Company anticipates increasing its
pharmaceutical inventory by approximately $120-$130 million to adequately stock the distribution warehouse. The Company expects such additional investment in inventory to be an ongoing working capital requirement. Implementation of the distribution
initiatives did not have a material financial impact during the quarter ended March 31, 2005.



Litigation



As disclosed in Part II,
Item 1, under the heading Legal Proceedings, the Company is aware that it and certain of its subsidiaries and affiliated practices have in the past been subject of qui tam lawsuits filed under seal alleging healthcare law violations.
Although the suits of which the Company is aware have been dismissed, because qui tam actions are filed under seal, there is a possibility that the Company could be the subject of other qui tam actions of which it is unaware.



From time to time, the Company becomes involved in disputes with affiliated practices. These
disputes typically relate to disagreements regarding performance under the service agreement with the physician group in question or to issues of contract interpretation. Generally, the Company is able to resolve such disputes without resorting to
litigation. There is a risk, however, that such disputes could result in litigation and in a deterioration or dissolution of the relationship with the physician group in question. Currently, the Company is in litigation with a practice consisting of
35 physicians affiliated under a net revenue model service agreement relating to the terms of, enforceability of, and performance under, its service agreement.



Assessing the Companys financial and operational exposure on litigation matters requires the application of substantial subjective judgments and estimates based
upon facts and circumstances, resulting in estimates that could change as more information becomes available.



NOTE 9  RECENT PRONOUNCEMENTS



In December 2004, the FASB issued Statement No. 123(R), Share-Based Payment, an amendment of FASB Statements No. 123 and 95, that addresses the accounting for share-based payment transactions in which an
enterprise receives employee services in exchange for either equity instruments of the enterprise or liabilities that are based on the fair value of the enterprises equity instruments or that may be settled by the issuance of such equity
instruments. The proposed statement eliminates the ability to account for share-based compensation transactions using the intrinsic value method as prescribed by the Accounting Principles Board, or APB, Opinion No. 25, Accounting for Stock
Issued to Employees, and generally requires that such transactions be accounted for using a fair-value-based method and recognized as expenses in the Companys consolidated statement of income. The standard requires that the modified
prospective method be used, which requires that the fair value of new awards granted from the beginning of the period of adoption (plus unvested awards at the date of adoption) be expensed over the vesting period. The statement requires

companies to assess the most appropriate model to calculate the value of the options. The Company currently uses the
Black-Scholes option pricing model to value options, and is currently assessing which model to use in the future under the new statement and may deem an alternative model to be more appropriate. The use of a different model to value options may
result in a different fair value than the use of the Black-Scholes option pricing model. In addition, a number of other requirements exist under the standard that will result in differing accounting treatment than currently required. These
differences include, but are not limited to, the accounting for the tax benefit on employee stock options. The effective date of the standard for nonpublic companies is for annual fiscal periods beginning after December 15, 2005. This statement
could have a significant impact on the Companys consolidated statement of income, as it will be required to expense the fair value of its stock option grants, rather than disclose the impact on its consolidated net income (within its footnotes
to the financial statements), as is the Companys current practice.



In
March 2005, the FASB issued Interpretation No. 47, Accounting for Conditional Retirement Obligations  an Interpretation of FASB Statement No. 143 (FIN 47). This interpretation clarifies the definition of conditional
asset retirement obligations as used in FASB Statement No. 143. The definition refers to the legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may
not be within the control of the entity. This statement is effective for fiscal years ending after December 15, 2005 and will not have a material impact on the Companys Consolidated Financial Statements.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF

OPERATIONS



ITEM 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS



Introduction



The following discussion should be read in conjunction with the financial statements, related notes, and other financial information appearing elsewhere in this report. In addition, see Forward-Looking
Statements and Risk Factors included in our Registration Statement on Form S-4, filed with the SEC December 17, 2004, as amended, and subsequent filings.



General



We provide comprehensive services to our network of affiliated practices, made up of more than 900 affiliated physicians in 470 locations, with the mission of expanding access to and improving the quality of cancer
care in local communities. The services we offer include:



| |  | Medical Oncology Services.We purchase and manage specialty oncology pharmaceuticals for our affiliated practices. Annually, we are responsible for purchasing, delivering and
managing more than $1.4 billion of pharmaceuticals through a network of 46 licensed pharmacies, 146 pharmacists and 287 pharmacy technicians. Under our physician practice management arrangements, we act as the exclusive manager and administrator of
all day-to-day non-medical business functions connected with our affiliated practices. As such, we are responsible for billing and collecting for medical oncology services, physician recruiting, data management, accounting, systems and capital
allocation to facilitate growth in practice operations.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Cancer Center Services.We develop and manage comprehensive, community-based cancer centers, which integrate all aspects of outpatient cancer care, from laboratory and
radiology diagnostic capabilities to chemotherapy and radiation therapy. We have developed and operate 85 integrated community-based cancer centers and manage over one million square feet of medical office space. We also have installed and manage 27
Positron Emission Tomography (PET) Systems.
|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Cancer Research Services.We facilitate a broad range of cancer research and development activities through our network. We contract with pharmaceutical and biotechnology
firms to provide a comprehensive range of services relating to clinical trials. We currently supervise 88 clinical trials, supported by our network of approximately 300 participating physicians in more than 200 research locations.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



We provide these services through two business models: the
physician practice management (PPM) model, under which we provide all of the above services under a single contract with one fee based on overall performance; and our pharmaceutical service line model, under which medical oncology practices contract
with the company to purchase only the pharmaceutical aspects of medical oncology services. Most of our revenues (88.7% during the first quarter 2005) are derived under the PPM model.



The Merger Transaction



On March 20, 2004, Holdings (which was formerly known as Oiler Holding Company) and its wholly-owned subsidiary, Oiler Acquisition Corp., entered into a merger agreement
with US Oncology pursuant to which Oiler Acquisition Corp. was merged with and into US Oncology, with US Oncology continuing as the surviving corporation and a wholly-owned subsidiary of Holdings.



On August 20, 2004, the merger was consummated, and we became a wholly-owned subsidiary of
Holdings. The merger was valued at approximately $1.6 billion. In the transaction, all of our former stockholders (other than WCAS, its affiliates, and certain members of management and continuing shareholders) received $15.05 per share in

cash for our common stock. Holders of our stock options received cash equal to (a) $15.05 minus the exercise price of
the option multiplied by (b) the number of shares subject to the options. Physicians who were entitled to receive shares of common stock at future dates as part of the consideration for affiliating with us instead received $15.05 per share of such
stock, in cash, at the time of the merger. After the merger, our common stock was delisted from the NASDAQ Stock Market and we became a private company.



The funds necessary to consummate the August Transactions were approximately $1,570.5 million, including approximately $1,185.0 million to pay the then current
stockholders, option holders and holders of outstanding rights to receive shares of our common stock pursuant to delayed share delivery agreements and all amounts due under the merger agreement, approximately $281.1 million to repay existing
indebtedness and approximately $104.4 million to pay related fees of approximately $50.1 million and expenses of approximately $54.3 million. Prior to the merger, 14,307,501 shares of our common stock then owned by Welsh Carson IX and its
affiliates, valued at $215.3 million, were contributed to Holdings in exchange for shares of common and participating preferred stock in Holdings. Upon consummation of the merger, those shares were cancelled without payment of any merger
consideration.



The August Transactions were financed by:



| |  |  | a cash common and preferred equity investment in Holdings by Welsh Carson IX and its related equity investors of $302.4 million, which funds were contributed to us by Holdings;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the borrowings by us of $400.0 million in term loans under the existing senior secured credit facility;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | $245.0 million of cash on hand at the closing date; and
| | - |  | -------------------------------------------------------



| |  |  | the issuance by us of $300.0 million aggregate principal amount of 9% senior notes and $275.0 million aggregate principal amount of 103/4% senior subordinated
notes.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



The August Transactions were accounted for under
the purchase method of accounting prescribed in Statement of Financial Accounting Standards No. 141, Business Combination, (SFAS No. 141), with intangible assets recorded in accordance with SFAS No. 142, Goodwill and Other
Intangible Assets (SFAS No. 142). The purchase price, including transaction-related fees, was allocated to our tangible and identifiable intangible assets and liabilities based upon estimates of fair value, with the remainder allocated to
goodwill. In accordance with the provisions of SFAS No. 142, no amortization of indefinite-lived intangible assets or goodwill will be recorded. The table below illustrates the allocation of the purchase price as of March 31, 2005 (in millions):



|                                                   |  |   |          |  
|-------------------------------------------------- |  | - | -------- | -
|Cash and equity contributed by WCAS and affiliates |  | $ | 517.8    |  
|Total liabilities assumed                          |  |   | 1,321.8  |  
|Fair value of assets acquired                      |  |   | (1,104.7 | )
|                                                   |  |   |          |  
|Excess purchase price (goodwill)                   |  | $ | 734.9    |  
|                                                   |  |   |          |  



While we continue to obtain
information to refine the fair values of the assets acquired and the liabilities assumed, the allocation of the purchase price is substantially complete as of March 31, 2005. As we complete our tax filings for the period ended with the August
Transactions, additional adjustments may be required to deferred tax balances. Adjustments, if any, attributable to the tax returns for the period ended August 20, 2004 will be considered a result of the August Transactions and may result in
additional adjustments to the purchase price allocation and the amount of goodwill. In accordance with the provisions of SFAS No. 142, no amortization of indefinite-lived intangible assets or goodwill will be recorded. We expect that a final
allocation of the purchase price will be completed no later than June 30, 2005.



Subsequent to the initial capitalization, additional capital contributions of $40.0 million were received from Holdings. The contribution represents the proceeds from a private equity offering to certain affiliated physicians and employees
of the company.

OF OPERATIONScontinued



In connection with the August Transactions, we incurred merger-related charges of $56.2 million. This amount includes
loss on early extinguishment of debt of $38.3 million and merger-related expenses of $17.9 million. Included in merger-related charges are legal costs of $3.8 million, advisory fees of $6.0 million and other fees and expenses of $8.1 million.
Merger-related charges, including early extinguishment of debt, amounted to $47.9 million for the predecessor company compared to $8.3 million for the successor company.



During the quarter ended March 31, 2005, Holdings, whose sole asset is its investment in US Oncology, Inc., issued $250.0 million of Senior
Floating Rate Notes, due 2015 (the Notes). The Notes are senior unsecured obligations of US Oncology Holdings and bear interest at a floating rate, reset semi-annually, equal to 6-month LIBOR plus 5.25 percent. In connection with the
financing, Holdings entered into an interest rate swap arrangement, effectively fixing the interest rate at 9.4 percent for a period of two years. Because Holdings sole asset is its investment in US Oncology, the Company plans to provide funds
to service the debt provisions through the payment of dividends to Holdings.



Proceeds from the offering were used to pay a special dividend of $250.0 million to stockholders of Holdings in March, 2005. The payment of the special dividend triggered a payment obligation of $14.5 million under the Holdings long-term
incentive plan, and Holdings incurred $7.2 million in expenses related to the offering. These amounts were financed with a dividend from US Oncology to US Oncology Holdings declared during the first quarter of 2005 and paid in the second quarter of
2005.



The carrying value of our goodwill is subject to impairment tests under
the requirements of SFAS No. 142. Goodwill was allocated to each of our reporting units based on their fair values at the date of the August Transactions. On an ongoing basis, we will perform impairment tests of the goodwill by comparing the fair
value of the reporting units discounted cash flows with their carrying values. The fair value is calculated using discounted cash flows, market multiples and market capitalization, as well as EBITDA analyses. We perform impairment tests on an
ongoing basis annually, more frequently in the event of any impairment indicators.



Our Strategy



Our mission is to increase access to and advance
the delivery of high-quality cancer care in America. We do this by offering services to physicians to enable them to provide cancer patients with a full continuum of care, including professional medical services, chemotherapy infusion, radiation
oncology, diagnostic services, access to clinical trials, patient education and other services, primarily in a community setting. We aim to enhance efficiency and lower cost structures at our affiliated practices, while enabling them to continue to
deliver quality patient care.



We believe that today, particularly in light of
recent changes in Medicare reimbursement and continued pressures on overall reimbursement, the most successful oncology practices will be those that have a preeminent position in their local market, that are diversified beyond medical oncology and
that have implemented efficient management processes. We believe that our services best position practices to attain these characteristics. At the same time, the economics of healthcare and the aging of the American population mean that pressures to
reduce health care costs and increase efficiency of medical practice operations will continue. We believe that community-based oncology care is the most patient-friendly and cost-effective care available, and we believe that we can continue to
enhance practice efficiency within the community context.



In all of our
practices, we continue to focus on initiatives that enhance efficiency. For example, we share best practices regarding efficient practice management, pharmaceutical use, practice staffing and other strategies across our network. In addition, we
assist our practices in their implementation of programs designed to enhance the quality and convenience of patient care. We also manage development of additional practice sites and assist practices in maintaining adequate reimbursement rates.



Also, during 2004 we acquired electronic medical record software called
iKnowMed, along with its technical development team and related assets located in Berkeley, CA. We recently commenced implementation of iKnowMed at selected affiliated practices. We believe that continued implementation of information systems and
analytical tools at our affiliated practices will improve patient care, efficiency, and our ability to provide information services.

Another key initiative is expanding our network. We plan to grow in two ways. First, we seek to enter into
comprehensive service agreements with practices in new markets, including those where we already have a regional presence. By seeking out new markets we can grow our national presence while taking advantage of the efficiencies that result from
leveraging existing regional and national infrastructure and capabilities. Second, we intend to expand our existing markets both by assisting practices with individual physician recruitment and by affiliating or facilitating affiliation with already
established practices. On a local level, this will help our affiliated practices solidify their standing in local communities while taking advantage of efficiencies that result from leveraging existing local assets and infrastructure.



We are also in the process of developing a specialty distribution business for oncology
pharmaceuticals. During the quarter ended March 31, 2005, we entered into a lease for a warehouse facility in Fort Worth, Texas to house the distribution function, began implementation of a distribution system and recruited key members of a
distribution management team. Implementation of the distribution initiatives did not have a material financial impact during the first quarter of 2005. During 2005, we will continue to build and acquire infrastructure and systems for distribution,
with the expectation that we will commence providing distribution services (for certain manufacturers) to our practices during the fourth quarter of 2005. Our intention is to continue expanding distribution until we operate our own distribution
system for substantially all of our affiliated practices and products. During implementation of our distribution function, our existing distributor will continue to provide distribution services to our network. We believe our own distribution
operation will give us an opportunity to enhance efficiency within our network, and will afford us the opportunity to ensure the safety and authenticity of drugs used by our practices as a result of our control of the pharmaceuticals at all times
from the manufacturer to the patient. We also intend to continue to expand the other types of services we provide to pharmaceutical manufacturers.



Economic Models



Most of our revenue is derived under the PPM model. Under the PPM model, we provide all of our services to a physician practice under a single management agreement under which we are appointed exclusive business
manager, responsible for all of the non-clinical aspects of the physicians practice.



Our PPM agreements are long-term agreements (generally with initial terms of 25 to 40 years) and cannot be terminated unilaterally without cause. Physicians joining the PPM practices are required to enter into
employment or non-competition agreements with the practice. Prior to 2002 and to a limited extent in 2005, we paid consideration to physicians in physician groups in exchange for the groups selling us operating assets and entering into such
long-term contracts or joining an already affiliated group. Historically, we also have helped affiliated groups expand by recruiting individual physicians without buying assets or paying consideration for service agreements. We intend to continue to
expand our business, both by recruiting new physicians and by affiliating with new groups.



Under most of our PPM agreements, we are compensated under the earnings model. Under that model, we are reimbursed for all expenses we incur in connection with managing a practice, and are paid an
additional fee based upon a percentage of the practices earnings before income taxes, subject to certain adjustments. During the first quarter of 2005, 81.4% of our revenue was derived from affiliated practices managed under agreements under
the earnings model. In some states, our agreements provide for a fixed management fee.



Of our first quarter 2005 revenue, 9.7% was derived under the service line model. Under our service line agreements, fees include payment for pharmaceuticals and supplies used by the group, reimbursement for certain pharmacy related
expenses and payment for the other services we provide. Rates for our services typically are based on the level of services required by the practice.



Realignment of Net Revenue Model Practices



Under the net revenue model, our fee consists of a fixed amount, plus a percentage of net revenues, plus, if certain performance criteria are met, a performance fee.
Under these agreements, once we have been reimbursed for expenses, the practice is entitled to retain a fixed portion of revenues before any additional service fee is paid to us. The effect of this priority of payments is that we bear a
disproportionate share of increasing practice costs, since if insufficient funds exist to pay both our fee and the fixed amount to be retained by the practice, the entire amount of

AND RESULTS
OF OPERATIONScontinued



the shortfall reduces our management fee. Rapidly increasing pharmaceutical costs have increased practice revenues
and thus the amounts retained by physicians. At the same time rising costs have eroded margins, leaving less available to pay our management fees.



The net revenue model does not appropriately align our and our practices economic incentives, since the parties do not have similar motivation to control costs or
efficiently utilize capital. For this reason, we have been seeking to convert net revenue model practices to the earnings model since the beginning of 2001. In some cases, net revenue model practices have converted instead to the service line model
or disaffiliated entirely. Of our 2000 revenue, 56.3% was derived from net revenue model practices, while only 7.3% of our first quarter 2005 revenue was derived from practices under the net revenue model. We no longer enter into new affiliations
under the net revenue model.

Critical Accounting Policies and Estimates



Our discussion and analysis of our financial condition and results of operations are based upon our unaudited condensed consolidated
financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial statements. The preparation of these financial statements requires management to make
estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate these estimates, including those related to service
agreements, accounts receivable, intangible assets, goodwill, income taxes, and contingencies and litigation. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances.
These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.



Actual results may differ from those estimates under different assumptions or conditions. In addition, as circumstances change, we may revise the basis of our estimates
accordingly. For example, in the past we have recorded charges to reflect revisions in our valuations of accounts receivable as a result of actual collections patterns or a sale of accounts receivable. We maintain decentralized billing systems and
continue to upgrade and modify those systems. We take this into account as we continue to evaluate receivables and record appropriate reserves, based upon the risks of collection inherent in such a structure. In the event subsequent collections are
higher or lower than our estimates, results of operations in subsequent periods could be either positively or negatively impacted as a result of such prior estimates. This risk is particularly relevant for periods in which there is a significant
shift in reimbursement from large payors, such as the recent changes in Medicare reimbursement.



Please refer to the Critical Accounting Policies section of our Registration Statement on Form S-4, filed with the SEC December 17, 2004, as amended, and subsequent filings, for a discussion of our
critical accounting policies. Management believes such critical accounting policies affect the more significant judgments and estimates used in the preparation of our consolidated condensed financial statements. These critical accounting policies
include our policy of non-consolidation of the results of affiliated practices, revenue recognition (including calculation of physician compensation), general estimates of accruals, including accruals relating to accounts receivable, and intangible
asset amortization and impairment.



Recent Pronouncements



In December 2004, the FASB issued Statement No. 123(R), Share-Based Payment, an
amendment of FASB Statements No. 123 and 95, that addresses the accounting for share-based payment transactions in which an enterprise receives employee services in exchange for either equity instruments of the enterprise or liabilities that
are based on the fair value of the enterprises equity instruments or that may be settled by the issuance of such equity instruments. The proposed statement eliminates the ability to account for share-based compensation transactions using the
intrinsic value method as prescribed by the Accounting Principles Board, or APB, Opinion No. 25, Accounting for Stock Issued to Employees, and generally requires that such transactions be accounted for using a fair-value-based method and
recognized as expenses in our consolidated statement of income. The standard requires that the modified prospective method be used, which requires that the fair value of new awards granted from the beginning of the period of adoption (plus unvested
awards at the date of adoption) be expensed over the vesting period. The statement requires companies to assess the most appropriate model to calculate the value of the options. We currently use the Black-Scholes option pricing model to value
options and are currently assessing which model to use in the future under the new statement and may deem an alternative model to be more appropriate. The use of a different model to value options may result in a different fair value than the use of
the Black-Scholes option pricing model. In addition, a number of other requirements exist under the standard that will result in differing accounting treatment than currently required. These differences include, but are not limited to, the
accounting for the tax benefit on employee stock options and for stock issued under employee stock purchase plans. The effective date of the standard for nonpublic companies is for annual fiscal periods beginning after December 15, 2005.



This proposed statement could have a significant impact on our consolidated statement of
income, as we will be required to expense the fair value of our stock option grants, rather than disclose the impact on our consolidated net income (within its footnotes to the financial statements), as is our current practice.

In March 2005, the FASB issued Interpretation No. 47, Accounting for Conditional Retirement Obligations 
an Interpretation of FASB Statement No. 143 (FIN 47). This interpretation clarifies the definition of conditional asset retirement obligations as used in FASB Statement No. 143. The definition refers to the legal obligation to
perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. This statement is effective for fiscal years ending after December 15,
2005 and will not have a material impact on our Consolidated Financial Statements.



From time to time, the FASB, the SEC and other regulatory bodies seek to change accounting rules, including rules applicable to our business and financial statements. We cannot assure you that future changes in accounting rules would not
require us to make restatements.



Discussion of Non-GAAP Information



In this document, we use a certain measurement of our performance that is
not calculated in accordance with generally accepted accounting principles of the United States (GAAP). In this document, we use the term EBITDA. EBITDA is earnings before interest and other expense, net, taxes, depreciation,
amortization and amortization of stock compensation. EBITDA is not calculated in accordance with GAAP. EBITDA is derived from relevant items in our GAAP financial statements. A reconciliation of EBITDA to the income statement is included in this
document.



We believe EBITDA is useful to investors in evaluating the value of
companies in general, and in evaluating the liquidity of companies with debt service obligations and their ability to service their indebtedness. EBITDA also excludes non-recurring and extraordinary items because management believes excluding such
items provides a better representation of our ongoing operations. Management uses EBITDA to evaluate our liquidity and financial condition, both with respect to the business as a whole and with respect to individual sites.



Management believes that EBITDA is useful to investors, since it provides investors with
additional information that is not directly available in a GAAP presentation. In all events, EBITDA is not intended to be a substitute for GAAP measures, and investors are advised to review such non-GAAP measures in conjunction with GAAP information
provided by us.

We provide the following services to
physician practices: medical oncology services, cancer center services, and cancer research services. We currently earn revenue from physician practices under two models, the PPM model, and the service line model. Under the PPM model, we enter into
long term agreements with affiliated practices to provide comprehensive services, including all those described above, and the practices pay us a service fee and reimburse all expenses. Under the service line model, we offer medical oncology
services and cancer research services under separate agreements for each service line.



We derive revenue primarily in four areas:



| |  | PPM service fee revenues. Under the PPM model, we recognize revenues derived from amounts we bill and collect on behalf of affiliated practices, which are reduced by the
amounts retained by those practices under our contracts. PPM service fee revenue is recorded when services are rendered based on established or negotiated rates reduced by contractual adjustments and allowances for doubtful accounts and by the
amounts retained by practices. Differences between estimated contractual adjustments and final settlements are reported in the period when final settlements are determined.

| |  | Service line fees. In the medical oncology services area under our service line agreements, we bill practices on a monthly basis for services rendered. These revenues include
payment for all of the pharmaceutical agents used by the practice for which we must pay the pharmaceutical manufacturers, and a service fee for the pharmacy related services we provide.
|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | GPO, data and other pharmaceutical service fees. We receive fees from pharmaceutical companies for acting as a GPO for our affiliated practices, as well as for providing
informational and other services to pharmaceutical companies. GPO fees are typically based upon the volume of drugs purchased by the practices. Fees for other services include amounts paid for data we collect and compile, as well as fees for other
informational services we provide to pharmaceutical companies.
|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Clinical Research fees. We receive fees for clinical research services from pharmaceutical and biotechnology companies. These fees are separately negotiated for each study
and typically include some management fee, as well as per patient accrual fees and fees for achieving various study milestones.
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



A portion of our revenue under our PPM arrangements and our service line arrangements with affiliated practices are derived from sales of pharmaceutical products and are
reported as product revenues. Our remaining revenues are reported as service revenues. Physician practices that enter into comprehensive service agreements with us receive a broad range of services and receive pharmaceutical products. These products
and services represent multiple deliverables delivered under a single contract, with a single fee. We have analyzed the component of the contract attributable to the provision of products (pharmaceuticals) and the component of the contract
attributable to the provision of services and attributed fair value to each component.



We retain all amounts we collect in respect of practice receivables. On a monthly basis, we calculate what portion of their revenues our affiliated practices are entitled to retain by subtracting our accrued fees and accrued practice
expenses from accrued revenues. We pay practices this remainder in cash, which they use primarily for physician compensation. These amounts we remit to physician groups are excluded from our revenue, because they are not part of our fees. By paying
physicians on a cash basis for accrued amounts, we finance their working capital.



Revenues for the quarter ended March 31, 2005 were $584.6 million compared to $525.0 million for the quarter ended March 31, 2004, an increase of 11.4%.



For the first quarter of 2005, product revenues increased to $368.2 million from $332.5 million for the first quarter of 2004, an increase
of $35.7 million or 10.7%. This increase is attributable to growth in pharmaceutical revenue, combined with the net addition of 22 medical oncologists affiliated with us since the first quarter of 2004.



Service revenues for the first quarter of 2005 increased to $216.4 million compared to $192.5
million in the same quarter last year, an increase of $23.9 million or 12.4%. This increase is due to the increases in intensity modulated radiation therapy (IMRT), position emission tomography (PET), computerized tomography (CT) services for
patients and pharmaceutical service revenues.



The following table reflects our
revenue by segment for the three months ended March 31, 2004 and 2005 (in thousands):

Medicare and Medicaid are the
practices largest payors. For the three months ended March 31, 2004 and 2005, the affiliated practices derived approximately 42% and 41%, respectively, of their net patient revenue from services provided under the Medicare program and
approximately 3% of their net patient revenue from services provided under the state Medicaid programs. Capitation revenues were less than 1% of total net patient revenue in both periods. Changes in the payor reimbursement rates, particularly
Medicare and Medicaid, or affiliated practices payor mix can materially and adversely affect our revenues.

OF OPERATIONScontinued



Cost of Products. Cost of products, which includes drugs, medications and other supplies used by the
practices, increased from $306.8 million in the first quarter of 2004 to $351.0 million in the same period of 2005, an increase of $44.2 million, or 14.4%. As a percentage of revenue, pharmaceuticals and supplies increased from 58.4% in the first
quarter of 2004 to 60.0% in the same period in 2005, primarily because of increased product revenues.



Effective January 1, 2005, Medicare changed the way in which it reimburses providers for oncology pharmaceuticals administered in physicians offices, including those in our network. Medicare now pays oncologists
the average sales price, or ASP, for the drug plus 6 percent. Previously, Medicare reimbursed physicians for oncology pharmaceuticals based on average wholesale price, or AWP, which is significantly higher than ASP. During 2004, reimbursement for
outpatient oncology drugs was generally 85 percent of AWP. This shift in reimbursement methodology represented approximately a 15 percent reduction in the amount of reimbursement for oncology pharmaceuticals.



Adoption of ASP pricing by Medicare, combined with the importance of pharmaceuticals to our
business and concentration of our purchases with a limited number of manufacturers, represents a significant risk for the Company. Nearly all of our pricing advantage relative to ASP is derived from purchases of drugs from a small number of
manufacturers. We believe that implementation of ASP-based pricing will likely reduce the amount of differential pricing that is available to us in the marketplace, which is one of our key competitive strengths.



ASP for the second quarter of 2005 will result in reimbursement for pharmaceuticals
administered by affiliated practices that is approximately 5 percent lower than in the first quarter of 2005. The adverse impact of ASP implementation, including the further reduction in the second quarter, is generally consistent with the
Companys previously published estimates of its impact; however, the impact has been partially mitigated by the overall growth of affiliated practices revenues.



Operating Compensation and Benefits. Operating compensation and benefits, which includes salaries and wages of our field-level
employees and the practices employees (other than physicians), increased from $92.7 million in the first quarter of 2004 to $100.0 million in the first quarter of 2005, an increase of $7.3 million, or 7.9%. As a percentage of revenue,
operating compensation and benefits decreased from 17.7% in the first quarter of 2004 to 17.1% in the first quarter of 2005. The decrease as a percentage of revenue is primarily attributable to economies of scale resulting from the increase in
pharmaceutical revenues, diagnostic revenues and radiation revenues.



Other
Operating Costs. Other operating costs, which consist of rent, utilities, repairs and maintenance, insurance and other direct field costs, increased from $56.8 million in the first quarter of 2004 to $58.2 million in the first quarter of 2005,
an increase of $1.4 million, or 2.5%. As a percentage of revenue, other operating costs decreased from 10.8% in the first quarter of 2004 to 10.0% in the first quarter of 2005 as a result of growth in pharmaceutical, diagnostic and radiation
revenue.



General and Administrative. General and administrative
expenses increased from $12.7 million in the first quarter of 2004 to $15.4 million in the first quarter of 2005, an increase of $2.7 million, or 21.3%, primarily due increases in our marketing and development initiatives, along with amortization of
non-cash compensation expense associated with restricted stock grants during the first quarter of 2005. As a percentage of revenue, general and administrative costs increased from 2.4% in the first quarter 2004 to 2.6% in the first quarter 2005.



EBITDA.Overall, we experienced a decline in operating margins with
earnings before taxes, interest, depreciation, amortization and amortization of stock compensation. EBITDA, as a percentage of revenue, decreased from 10.7% in the first quarter of 2004 to 7.9% in the first quarter of 2005.

Medical oncology services EBITDA
margin decreased from 10.5% in the first quarter of 2004 to 10.3% in the first quarter of 2005. This decrease is the result of the implementation of Medicare reimbursement changes, partially offset by growth in pharmaceutical revenues.



Cancer center services EBITDA margin increased from 34.7% in the first quarter of 2004 to
36.7% in the first quarter of 2005. This increase is attributable to exiting from unprofitable sites, investment in technology such as intensity modulated radiation therapy (IMRT), CT and PET, and an increase in the number of cancer centers (from 80
to 85) since the first quarter of 2004.



Unallocated corporate expenses EBITDA
decreased from ($12.7) million for the first quarter of 2004 to ($29.4) million for the first quarter of 2005. This decrease is attributable to the $14.5 million charge associated with our long-term cash incentive plan and $0.9 million of
amortization expense related to restricted stock grants, both of which were recorded during the first quarter of 2005.



Interest. Net interest expense increased from $4.4 million in the first quarter of 2004 to $20.5 million in the first quarter of 2005, an increase of $16.1
million. This increase is attributable to our increased indebtedness as a result of the August Transactions. As a percentage of revenue, net interest expense increased from 0.9% for the first quarter of 2004 to 3.5% for the first quarter of 2005.



Income Taxes. We recognized an effective tax rate of 38.5% for the
first quarter of 2004 and 40.2% for the first quarter of 2005. The increase is attributable to lower forecasted pre-tax income in 2005 (in proportion to our permanent differences) relating to expenses that are non-deductible for income tax purposes.



Net Income. Net income decreased from $20.1 million in the first
quarter of 2004 to $2.4 million in the first quarter 2005, a decrease of $17.7 million or 88.1%. Net income as a percentage of revenue decreased from 3.8% in the first quarter of 2004 to 0.4% in the first quarter of 2005. The decrease in net income
from the first quarter of 2004 is primarily the result of an increase in interest expense, along with compensation expense associated with the long-term incentive plan incurred during the first quarter of 2005.

MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS
OF OPERATIONScontinued



Liquidity and Capital Resources



As of March 31, 2005, we had net working capital of $212.1 million, including cash and cash equivalents of $98.5 million. We had current
liabilities of $438.6 million, including $11.1 million in current maturities of long-term debt, and $973.7 million of long-term indebtedness. During the first quarter of 2005, we provided $0.3 million in net operating cash flow, invested $19.1
million, and used cash from financing activities in the amount of $3.1 million. As of May 4, 2005, we had cash and cash equivalents of approximately $113 million.



Cash Flows from Operating Activities



During the first quarter of 2005, we provided $0.3 million in cash flows from operating activities as compared to providing $43.5 million in the comparable prior year
period. The decrease in cash flow is primarily due to the timing of the receipt of approximately $60 million in vendor rebates, along with an increase of two days in accounts receivable days outstanding. The vendor rebates were collected during
April 2005.



Cash Flows from Investing Activities



During the first quarter of 2004 and 2005, we used $21.5 million and $19.1 million for
investing activities, respectively. The investments primarily consisted of $21.5 million and $19.7 million in capital expenditures, including $19.4 million and $16.4 million relating to the development and construction of cancer centers,
respectively. Maintenance capital expenditures were $2.1 million and $3.3 million in the first quarters of 2004 and 2005, respectively.



Cash Flows from Financing Activities



During the first quarter of 2005, we used $3.1 million in cash for financing activities compared to cash provided of $5.5 million in the first quarter of 2004. The use of
cash in the first quarter of 2005 is primarily related to $14.9 million in repayments under our term loan facility, partially offset by $13.1 million in new borrowings and a $1.3 million equity contribution received from Holdings during the quarter.



During the quarter ended March 31, 2005, Holdings, whose sole asset is its
investment in US Oncology, Inc., issued $250.0 million of Senior Floating Rate Notes, due 2015 (the Notes). The Notes are senior unsecured obligations of Holdings and bear interest at a floating rate, reset semi-annually, equal to
6-month LIBOR plus 5.25 percent. Simultaneously with the financing, Holdings entered into an interest rate swap arrangement, effectively fixing the interest rate at 9.4 percent for a period of two years. Because Holdings sole asset is its
investment in US Oncology, we plan to provide funds sufficient to service the indebtedness through the payment of dividends to Holdings.



Payment of interest on the new Holdings notes will be financed through the payment of periodic dividends from us. During the period that the interest rate has been fixed,
interest expense will amount to approximately $23.5 million annually, and may be more or less than that amount thereafter. Certain restrictions in our note indentures and certain other circumstances could prevent payment of such a dividend by us in
the future, which could cause Holdings to default on its notes unless other sources of funding are available.

Anticipated Capital Requirements



We currently expect our principal uses of funds in the near future to be the following:



| |  |  | Investment in inventory, equipment and leasehold improvements for our distribution initiative.
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | Purchase of real estate and medical equipment for the development of new cancer centers, as well as installation of upgraded and replacement medical equipment at existing centers.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Payments made for acquisition of assets and additional consideration, if any, in connection with new practice affiliations.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | Funding of working capital, including advance purchases of pharmaceuticals for price-hedging purposes or to obtain certain rebates and discounts under contracts with volume-based
thresholds.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Investments in information systems, including systems related to new initiatives such as our electronic medical record product, iKnowMed, and our pharmacy distribution operations.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



For 2005, we anticipate expending $70-$80 million for the
development of cancer centers, purchase of clinical equipment and investment in information systems. We anticipate our specialty pharmacy distribution initiative in 2005 will require an investment of $15 million in systems, consultants and leasehold
improvements. In addition, we anticipate increasing our pharmaceutical inventory by approximately $120-$130 million to adequately stock the distribution warehouse. We expect such additional investment in inventory to be an ongoing working capital
requirement.



We expect to fund our current capital needs with (a) cash flow
generated from operations, (b) borrowings under the existing $160 million revolving credit facility, (c) lease or purchase money financing for certain equipment purchases and (d) issuing indebtedness to physicians in connection with new
affiliations. Our success in implementing our capital expenditure plans and our new distribution initiatives could be adversely impacted by poor operating performance resulting in reduced cash flow from operations. In addition, to the extent that
poor performance or other factors impact our compliance with financial and other covenants under our revolving credit facility, our ability to borrow under that facility or to find other financing sources could be limited. Furthermore, capital at
financing terms satisfactory to management may be limited, due to market conditions or operating performance.

Item 3. Quantitative and Qualitative Disclosures about Market Risks



In the normal course of business, our financial position is routinely subjected to a variety of risks. We regularly assess these risks and have established policies and business practices to protect against the
adverse effects of these and other potential exposures.



Among these risks is
the market risk associated with interest rate movements on outstanding debt. Any borrowings under the credit facility contain an element of market risk from changes in interest rates. As of March 31, 2005, we had no outstanding borrowings under our
credit facility. Historically, at times we have managed this risk, in part, through the use of interest rate swaps; however, no such agreements were entered into by the company in the first quarter of 2004 or 2005. We do not enter into interest rate
swaps or hold other derivative financial instruments for speculative purposes. We were not obligated under any interest rate swap agreements during the first quarter of 2004 or 2005.



During the quarter ended March 31, 2005, Holdings, whose sole asset is its investment in US Oncology, Inc., issued $250,000,000 of Senior
Floating Rate Notes, due 2015 (the Notes). The Notes are senior unsecured obligations of US Oncology Holdings and bear interest at a floating rate, reset semi-annually, equal to 6-month LIBOR plus 5.25 percent. In connection with the
financing, Holdings entered into an interest rate swap arrangement, effectively fixing the interest rate at 9.4 percent for a period of two years. The swap agreement, which has a notional amount of $250.0 million, was designed as a cash flow hedge
and qualifies for the shortcut method of accounting. The income statement effects of the swap agreement, along with the carrying value of the debt, related transaction costs and interest expense, are included in the financial statements of US
Oncology Holdings. Because Holdings sole asset is its investment in US Oncology, we plan to provide the necessary funds to service this debt obligation through the payment of dividends to Holdings.



For purposes of specific risk analysis, we use sensitivity analysis to determine the impact
that market risk exposures may have on us. The financial instruments included in the sensitivity analysis consist of all of our cash and equivalents, long-term and short-term debt and all derivative financial instruments.



To perform sensitivity analysis, we assess the risk of loss in fair values from the impact of
hypothetical changes in interest rates on market sensitive instruments. The market values for interest rate risk are computed based on the present value of future cash flows as impacted by the changes in the rates attributable to the market risk
being measured. The discount rates used for the present value computations were selected based on market interest rates in effect at March 31, 2005. The market values that result from these computations are compared with the market values of these
financial instruments at March 31, 2005. The differences in this comparison are the hypothetical gains or losses associated with each type of risk. A one percent increase or decrease in the levels of interest rates on variable rate debt with all
other variables held constant would not result in a material change to our results of operations or financial position or the fair value of our financial instruments.



Item 4. Controls and Procedures



We carried out
an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to
Exchange Act Rule 13a-15 as of the end of the period covered by this report. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective in timely alerting
them to material information relating to the Company (including its consolidated subsidiaries) required to be included in our periodic SEC filings.



There was no change in internal control over financial reporting that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to
materially affect, our internal control over financial reporting.



Management
previously acknowledged its responsibility for internal controls and seeks to continue to improve those controls. In addition, in order to achieve compliance with Section 404 of the Sarbanes-Oxley Act of 2002 within the prescribed period, we have,
since 2003, been engaged in a process to document and evaluate our internal controls over financial reporting. In this regard, management has dedicated internal resources, engaged outside consultants and adopted a detailed project work plan to (i)
assess the adequacy of our internal control over financial reporting, (ii) take steps to improve control processes where appropriate, (iii) validate through testing that controls are functioning as documented and (iv) implement a continuous

reporting and improvement process for internal control over financial reporting. During the second quarter of 2004, we commenced testing of
internal controls that we had previously documented as part of this process. The Company will first be subject to all of the requirements of Section 404, including inclusion of managements report on internal control over financial reporting
and the independent registered public accounting firms assessment of such internal controls when it files its annual report on Form 10-K with respect to its fiscal year ending December 31, 2006.

PART II  Other Information



ITEM 1. LEGAL PROCEEDINGS



The provision of medical services by our affiliated practices entails an inherent risk of professional liability claims. We do not control the practice of medicine by the clinical staff or their compliance with
regulatory and other requirements directly applicable to practices. In addition, because the practices purchase and prescribe pharmaceutical products, they face the risk of product liability claims. In addition, because of licensing requirements and
affiliated practices participation in governmental health care programs, we and affiliated practices are, form time to time, subject to governmental audits and investigations, as well as internally initiated audits, some of which may result in
refunds to governmental programs. Although we and our practices maintain insurance coverage, successful malpractice, regulatory or product liability claims asserted against us or one of the practices in excess of insurance coverage could have a
material adverse effect on us.



We have become aware that we and certain of our
subsidiaries and affiliated practices are the subject of qui tam lawsuits (commonly referred to as whistle-blower suits) that remain under seal, meaning they were filed on a confidential basis with a U.S. federal court and are not
publicly available or disclosable. The United States has determined not to intervene in any of the qui tam suits of which we are aware and all but one of such suits has been dismissed. The individuals who filed the remaining claim of which we
are aware may still pursue the litigation, although none of those individuals has indicated intent to do so. Because qui tam actions are filed under seal, there is a possibility that we could be the subject of other qui tam actions of
which we are unaware. We intend to continue to investigate and vigorously defend ourselves against any and all such claims, and we continue to believe that we conduct our operations in compliance with law.



Qui tam suits are brought by private individuals, and there is no minimum evidentiary
or legal threshold for bringing such a suit. The Department of Justice is legally required to investigate the allegations in these suits. The subject matter of many such claims may relate both to our alleged actions and alleged actions of an
affiliated practice. Because the affiliated practices are separate legal entities not controlled by us, such claims necessarily involve a more complicated, higher cost defense, and may adversely impact the relationship between us and the practices.
If the individuals who file complaints and/or the United States were to prevail in these claims against us, and the magnitude of the alleged wrongdoing were determined to be significant, the resulting judgment could have a material adverse financial
and operational effect on us including potential limitations in future participation in governmental reimbursement programs. In addition, addressing complaints and government investigations requires us to devote significant financial and other
resources to the process, regardless of the ultimate outcome of the claims.



We
and our network physicians are defendants in a number of lawsuits involving employment and other disputes and breach of contract claims. In addition, we are involved from time to time in disputes with, and claims by, our affiliated practices against
us. Although we believe the allegations are customary for the size and scope of our operations, adverse judgments, individually or in the aggregate, could have a material adverse effect on us.



Specifically, we are involved in litigation with one net revenue model practice made up of 35
physicians with which we are trying to negotiate a service agreement termination or conversion to the earnings model or service line model. We initiated arbitration proceedings pursuant to a provision in that service agreement providing for contract
reformation in certain events. The practice has countered with a lawsuit that alleges, among other things, that we have breached the service agreement and that our service agreement is unenforceable as a matter of public policy due to alleged
violations of health care laws. The practice is seeking unspecified damages and a termination of the contract. We believe the practices allegations are without merit.



We believe the allegations in suits against us are customary for the size and scope of our operations. However, adverse judgments,
individually or in the aggregate, could have a material adverse effect on us.
