The preparation of financial statements
in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.



Principles of Consolidation



The condensed consolidated financial statements include the accounts of Invitrogen Corporation and its majority owned or controlled subsidiaries
collectively referred to as Invitrogen (the Company). All significant intercompany accounts and transactions have been eliminated.



Long-Lived Assets



The Company periodically re-evaluates the original assumptions and rationale utilized in the establishment of the carrying value and estimated lives of
its long-lived assets. The criteria used for these evaluations include managements estimate of the assets continuing ability to generate income from operations and positive cash flow in future periods as well as the strategic
significance of any intangible asset to the Companys business objectives. If assets are considered to be impaired, the impairment recognized is the amount by which the carrying value of the assets exceeds the fair value of the assets, which is
determined by applicable market prices, when available.

Computation of Earnings Per
Share



Basic earnings per share was computed by
dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur from the following items:



| |  |  | Convertible subordinated notes and contingently convertible notes where the effect of those securities is dilutive;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | Dilutive stock options; and

In September 2004, the Emerging Issues Task Force reached a final consensus on Issue No. 04-8, The
Effect of Contingently Convertible Debt on Diluted Earnings per Share (EITF 04-8). Contingently convertible debt instruments are financial instruments that add a contingent feature to a convertible debt instrument. The conversion feature is
triggered when one or more specified contingencies occur and at least one of these contingencies is based on market price. Prior to the issuance of EITF 04-8, FASB Statement of Financial Accounting Standards No. 128, Earnings Per Share
(SFAS 128) had been widely interpreted to allow the exclusion of common shares underlying contingently convertible debt instruments from the calculation of diluted earnings per share in instances where conversion depends on the achievement of a
specified market price of the issuers shares. The consensus requires that these underlying common shares be included in the diluted earnings per share computations, if dilutive, regardless of whether the market price contingency or any other
contingent factor has been met. The consensus, which is effective for reporting periods that ended after December 15, 2004, requires the restatement of diluted earnings per share for all prior periods presented. The Company has two series of
contingently convertible debt instruments: the first series, $450.0 million principal amount of 11/2%
convertible senior notes due February 15, 2024 (2024 Notes) and the second series, $350.0 million principal amount of 2% convertible senior notes due August 1, 2023 (2023 Notes), which contain certain contingent conversion features, including
certain market value triggers. Accordingly, EITF 04-8 has been applied to the Companys diluted earnings per share calculation for the three months ended March 31, 2005 and 2004.



In December 2004, the Company completed an exchange of 83% and 91% of the
2023 and 2024 Notes (the New Notes), respectively. The New Notes require the Company to settle the par value of such notes in cash and deliver shares only for the differential between the stock price on the date of conversion and the base conversion
price. As such, Emerging Issues Task Force Issue No. 90-19, Convertible Bonds with Issuer Option to Settle for Cash Upon Conversion (EITF 90-19) and EITF 04-8 require the Company to use the treasury stock equivalent method to calculate
diluted earnings per share. The treasury stock equivalent method requires the Company to include, in its calculation of diluted earnings per share, shares issuable if the notes were to be converted at the end of the reporting period in which they
were outstanding. Under the treasury stock equivalent method, the number of shares of the Companys common stock deemed to be outstanding for the purpose of calculating diluted earnings per share is increased when the average closing sale price
of our common stock at the end of a reporting period exceeds the base conversion prices of the notes. The if-converted method continues to be used for non-contingent convertible notes and for the portion of the 2023 and 2024 contingent convertible
notes that remain outstanding after the exchange.

Accounting for Stock-Based
Compensation



The Company accounts for its employee
stock option plans and employee stock purchase plan under the recognition and measurement principles of APB Opinion No. 25, Accounting for Stock Issued to Employees, and has adopted the disclosure only provisions of Statement of
Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation (SFAS 123). Accordingly, no compensation cost has been recognized for the fixed stock option plans or stock purchase plan under the fair value recognition
provisions of SFAS 123. The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of SFAS 123 to stock-based employee compensation.

Recent Accounting Pronouncements



On December 16, 2004, the Financial Accounting
Standards Board (FASB) issued Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (SFAS 123R), which is a revision of Statement of Financial Accounting Standards No. 123, Accounting for
Stock-Based Compensation (SFAS 123). SFAS 123R supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees, and amends Statement of Financial Accounting Standards No. 95, Statement of Cash Flows (SFAS 95).
Generally, the approach in SFAS 123R is similar to the approach described in SFAS 123. However, SFAS 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on
their fair values. Pro forma disclosure is no longer an alternative. SFAS 123R must be adopted no later than January 1, 2006. Early adoption will be permitted in periods in which financial statements have not yet been issued. The Company expects to
adopt SFAS 123R on January 1, 2006.



As permitted by SFAS 123,
the Company currently accounts for share-based payments to employees using Opinion 25s intrinsic value method and, as such, generally recognizes no compensation cost for employee stock options. Accordingly, the adoption of SFAS 123Rs
fair value method will have a significant impact on our results of operations, although it will have no impact on our overall financial position. Determining the exact impact of adoption of SFAS 123R cannot be predicted at this time because it will
depend on levels of share-based payments granted in the future and the assumptions for the variables which impact the computation. However, had the Company adopted SFAS 123R in prior periods, the impact of that standard would have approximated the
impact of SFAS 123 as described in the disclosure of pro forma net income and earnings per share elsewhere in Note 1 of the Companys condensed consolidated financial statements. SFAS 123R also requires the benefits of tax deductions in excess
of recognized compensation cost to be reported as a financing cash flow, rather than as an operating cash flow as required under current literature. This requirement will reduce the Companys net operating cash flows and increase net financing
cash flows in periods after adoption.



In December 2004, the
FASB issued FASB Staff Position No. FAS 109-1, Application of FASB Statement No. 109, Accounting for Income Taxes, for the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004 (FSP FAS
109-1). FSP FAS 109-1 clarifies that the deduction will be treated as a special deduction as described in Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes. As such, the special deduction has no
effect on deferred tax assets and liabilities existing at the date of enactment. The impact of the deduction will be reported in the period in which the deduction is claimed. The Company is currently assessing the impact of FSP FAS 109-1 on its
consolidated financial statements.



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

In November 2004, the FASB issued Statement of Financial Accounting Standards No. 151, Inventory
Costs, an amendment of ARB No. 43, Chapter 4 (SFAS 151). This statement amends the guidance in ARB No. 43 Chapter 4, Inventory Pricing, to clarify the accounting for abnormal amounts of idle facility expense, freight, handling
costs, and wasted material (spoilage). Paragraph 5 of ARB No. 43, Chapter 4, previously stated that  . . . under some circumstances, items such as idle facility expense, excessive spoilage, double freight, and rehandling costs may be so
abnormal to require treatment as current period charges . . . This statement requires that those items be recognized as current-period charges regardless of whether they meet the criterion of so abnormal. In addition, this
statement requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. The provisions of this statement will be effective for inventory costs during the fiscal years
beginning after June 15, 2005. The Company does not believe that the adoption of this statement will have a material impact on its financial condition or consolidated results of operations.



On October 22, 2004, the American Jobs Creation Act (AJCA) was signed into
law. The AJCA includes a special one-time 85 percent dividends received deduction for certain foreign earnings that are repatriated. In December 2004, the FASB issued FASB Staff Position No. FAS 109-2, Accounting and Disclosure Guidance for
the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of 2004 (FSP FAS 109-2). FSP FAS 109-2 provides accounting and disclosure guidance for this repatriation provision. The Company has begun its evaluation of the
effects of this provision. Although FSP FAS 109-2 is effective immediately, the Company will not be able to complete its evaluation until after Congress or the Treasury Department provides additional clarifying language on key elements of the
provision. Invitrogen expects to complete its evaluation of the effects of the repatriation provision within a reasonable period of time following the publication of the additional clarifying language.



At its September 29-30, 2004, meeting, the FASB reached a consensus on
Emerging Issues Task Force (EITF) Issue No. 04-8, The Effect of Contingently Convertible Debt on Diluted Earnings Per Share (EITF Issue 04-8), that contingently convertible debt instruments will be subject to the if-converted method
under SFAS 128, regardless of the contingent features included in the instrument. Under past practice, issuers of contingently convertible debt instruments exclude potential common shares underlying the debt instruments from the calculation of
diluted earnings per share until the market price or other contingency is met. The effective date for EITF Issue 04-8 is for reporting periods ending after December 15, 2004. The Company has applied the EITF guidance by retroactively restating
earnings per share for all applicable periods (see disclosure related to Computation of Earnings Per Share located elsewhere in this note).



In May 2004, the FASB issued FASB Staff Position No. 106-2, Accounting and Disclosure Requirements Related to the Medicare Prescription Drug,
Improvement and Modernization Act of 2003 (FSP 106-2). FSP 106-2 provides guidance on the accounting for the effects of the Act for employers that sponsor postretirement health care plans that provide prescription drug benefits. This FSP also
requires those employers to provide certain disclosures regarding the effect of the federal subsidy provided by the Act (the Subsidy). The guidance in FSP 106-2 related to the accounting for the Subsidy applies only to the sponsor of a
single-employer defined benefit postretirement health care plan for which (a) the employer has concluded that prescription drug benefits available under the plan to some or all the participants for some or all future years are actuarially
equivalent to Medicare Part D and thus qualify for the Subsidy under the Act and (b) the expected Subsidy will offset or reduce the employers share of the cost of the underlying postretirement prescription drug coverage on which the
Subsidy is based. This FSP also provides guidance for the disclosures about the effects of the Subsidy for an employer that sponsors a postretirement health care benefit plan that provides prescription drug coverage, but for which the employer has
not yet been able to determine actuarial equivalency. This FSP is effective for the first interim period beginning after June 15, 2004. The Company is investigating the impact of FSP 106-2s initial recognition, measurement and disclosure
provisions on its Dexter Postretirement Health and Benefit Program, but is currently unable to conclude whether the benefits provided by the plan are actuarially equivalent to Medicare Part D. As a result, measurement of the accumulated plan benefit
obligation and net periodic postretirement benefit cost does not reflect the effects of the Act on the Companys postretirement benefit plan. The Company does not expect FSP 106-2 to have a material impact on its consolidated financial
statements.

Purchased intangibles
are being amortized over a weighted average life of 4 years. An established client list, a history of operating margins and profitability, a strong scientific employee base and operations in an attractive market niche were among the factors that
contributed to a purchase price resulting in the recognition of goodwill. The Company believes none of the intangible assets and goodwill recognized will be deductible for federal income tax purposes, although a portion or the purchase price will be
deductible for certain state tax purposes.



As a result of the
integration of the business and the Companys implementation of a decision made by the board of directors of BioReliance to close duplicate facilities in Worchester, Massachusetts, prior to the acquisition, the Company has terminated 76
employees and relocated 8 employees to other sites. At March 31, 2005, the Company had $1.2 million remaining in accrued expenses and other current liabilities in the Condensed Consolidated Balance Sheets related to this integration. Activity for
accrued acquisition and business integration costs for the three months ended March 31, 2005, is as follows:

|4. | Segment Information
|-- | -------------------



The Company has two reportable segments: BioDiscovery and BioProduction.



The BioDiscovery product segment includes functional genomics, cell biology and drug discovery product lines. Functional
genomics encompasses products from the initial cloning and manipulation of DNA, to examining RNA levels and regulating gene expression in cells, to capturing, separating and analyzing proteins. These include the research tools used in reagent and
kit form that simplify and improve gene acquisition, gene cloning, gene expression, and gene analysis techniques. This segment also includes a full range of enzymes, nucleic acids, other biochemicals and reagents. These biologics are manufactured to
the highest research standards and are matched in a gene specific, validated manner (gene, orf, rnai, protein, antibodies, etc.) to ensure researchers the highest purity and scientific relevance for their experimentation. The Company also offers
software that enables more efficient, accelerated analysis and interpretation of genomic, proteomic and other biomolecular data for application in pharmaceutical, therapeutic and diagnostic development. The recent acquisitions of Zymed Laboratories,
Inc. (Zymed) and Dynal Biotech Holding AS (Dynal) have introduced and will continue to enable the Company to offer new technology and products, such as antibodies and proteins (Zymed) and magnetic beads used for biological separation (Dynal), which
is the first step in almost every biologic investigative or diagnostic process. See Notes 3 and 9 of the Notes to Condensed Consolidated Financial Statements.



The BioProduction product segment includes all of our cell culture products and biological testing services business. Products include sera, cell and
tissue culture media, reagents used in both life sciences research and in processes to grow cells in the laboratory, and to produce pharmaceuticals and other materials made by cultured cells. BioProduction services include testing to ensure that
biologics are free of disease-causing agents or do not cause adverse effects, characterization of products chemical structures, development of formulations for long-term stability, and validation of purification processes under regulatory
guidelines. The Company also manufactures biologics on behalf of clients both for use in clinical trials and for the worldwide commercial market.



The Company has no intersegment revenues that are material to the overall condensed consolidated financial statements. In addition, the Company does not
currently segregate assets by segment as a majority of the Companys total assets are shared or considered non-segment assets. As a result, the Company has determined it is not useful to assign its shared assets to individual segments.

|(1) | Unallocated items for the three months ended March 31, 2005 and 2004, include costs for purchase accounting inventory revaluations of $0.6 million and $10.3 million,
amortization of purchased intangibles of $25.9 million and $28.2 million, in-process research and development of $1.2 million and $0 and amortization of deferred compensation of $0.4 million and $0.4 million, respectively. These items are not
allocated by management for purposes of analyzing the operations since they are principally non-cash or other costs resulting primarily from business restructuring or purchase accounting that are separate from ongoing operations.

|6. | Commitments and Contingencies
|-- | -----------------------------



Operating Leases



During the three months ended March 31, 2005, the Company assumed an operating lease in conjunction with its acquisition of Zymed. The operating lease,
which expires in 2010, requires the Company to make payments of $1.2 million for the remainder of 2005, $1.4 million for 2006, $1.4 million for 2007, 2008 and 2009, with $0.7 million required for 2010. Future minimum lease payments were reduced by
$2.9 million as of March 31, 2005, due to the sublease of property associated with the acquisition of Informax in December 2002.



14



---

Letters of Credit



The Company had outstanding letters of credit totaling $9.6 million at March 31, 2005, of which $4.8 million was to support liabilities associated with
the Companys self-insured workers compensation programs and $4.8 million was to support its building lease requirements.



Executive Employment Agreements



The Company has employment contracts with key executives that provide for the continuation of salary if terminated for reasons other than cause, as
defined in those agreements. At March 31, 2005, future employment contract commitments for such key executives were approximately $5.9 million for the remainder of fiscal year 2005 and approximately $1.0 million for both fiscal year 2006 and 2007.



Guarantees



As part of the capital leases assumed in conjunction with the acquisition of
BioReliance, the Company guarantees the debt of an outside third party collateralized by the underlying asset, the construction of a manufacturing facility. The residual value guarantee is approximately $4.7 million as of March 31, 2005, of which it
is believed substantially all would be recoverable through various recourse provisions and an undeterminable recoverable amount based on the fair market value of the underlying assets. As of March 31, 2005, a $3.8 million liability for capitalized
lease obligations has been recorded, of which $0.3 million is classified as current portion of long-term obligations and $3.5 million as long-term obligations in the Condensed Consolidated Balance Sheets at March 31, 2005.



Contingent Acquisition Obligations



Pursuant to the purchase agreements for certain acquisitions, the Company
could be required to make additional contingent cash payments based on the achievement of certain operating results of the acquired companies. Payments aggregating a maximum of $87.3 million and certain other payments based upon certain percentages
of future gross sales of the acquired companies could be required through 2007. An additional payment of $30.0 million could be required of the Company based upon the achievement of several research and development milestones of a separate acquired
company through 2006.



Environmental Liabilities



The Company assumed certain environmental exposures as a result of its
merger with Dexter Corporation in 2000 and recorded reserves to cover estimated environmental clean-up costs. The environmental reserves, which are not discounted, were $7.9 million at March 31, 2005, and included current reserves of $0.8 million,
which are estimated to be paid during the next twelve months, and long-term reserves of $7.1 million. In addition, the Company has an insurance policy for these assumed environmental exposures. Based upon currently available information, the Company
believes that it has adequately provided for these environmental exposures and that the outcome of these matters will not have a material adverse effect on its consolidated results of operations.



Intellectual Properties



The Company is involved in various claims and legal proceedings of a nature
considered normal to its business, including protection of its owned and licensed intellectual property. The Company accrues for such contingencies when it is probable that a liability is incurred and the amount can be reasonably estimated. These
accruals are adjusted periodically as assessments change or additional information becomes available. Specific royalty liabilities related to acquired businesses have been recorded on the condensed consolidated financial statements at March 31,
2005.



Litigation



The Company is subject to potential liabilities under government regulations
and various claims and legal actions that are pending or may be asserted. These matters have arisen in the ordinary course and conduct of the Companys business, as well as through acquisitions, and some are expected to be covered, at least
partly, by insurance. Claim estimates that are probable and can be reasonably estimated are reflected as liabilities of the Company. The ultimate resolution of these matters is subject to many uncertainties. It is reasonably possible that some of
the matters that are pending or may be asserted could be decided unfavorably to the Company. Although the amount of liability at March 31, 2005, with respect to these matters cannot be ascertained, the Company believes that any resulting liability
should not materially affect its condensed consolidated financial statements.

|7. | Pension Plans and Postretirement Health and Benefit Program
|-- | -----------------------------------------------------------



The Company has several defined benefit pension plans covering its U.S. employees and employees in certain foreign countries. The Company also administers
the Dexter Postretirement Health and Benefit Program, which provides benefits to certain participants who are not employees of the Company but were employees of Dexter Corporation prior to the sale of its businesses and its merger with the Company.



The components of net periodic pension cost for the
Companys pension plans and postretirement health and benefit program for the three months ended March 31, 2005, and 2004, are as follows:

|8. | Income Taxes
|-- | ------------



Income taxes are determined using an estimated annual effective tax rate, which is less than the 35% U.S. federal statutory rate, primarily because of
lower tax rates in certain non-U.S. jurisdictions, export incentives and research and development tax credits available in the United States. The Company recognizes deferred tax assets and liabilities for temporary differences between the financial
reporting basis and the tax basis of the Companys assets and liabilities.



|9. | Subsequent Events
|-- | -----------------



On April 1, 2005, the Company completed the acquisition of Dynal Biotech Holding AS. The aggregate cash purchase price was 2.5 billion NOK or
approximately $399 million. The results of operations will be included in the Companys future financial statements from the respective date of acquisition.



On April 27, 2005, the Company entered into a secured line of credit that provides up to $250 million in borrowings at LIBOR
plus 0.15. The secured credit facility is collateralized by investments and matures on September 30, 2005. On April 28, 2005 the Company borrowed $124 million to repurchase $125 million of its 21⁄4% convertible subordinated notes due December 15,
2006, for less than par value. The amount available from the line of credit was $126 million upon completion of the repurchase of the convertible subordinated notes.

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



The following discussion and analysis of financial condition and results of
operations should be read in conjunction with the Unaudited Condensed Consolidated Financial Statements and Notes thereto included elsewhere in this report and the Consolidated Financial Statements and Notes thereto included in our annual report on
Form 10-K.



Forward-looking Statements



Any statements in this Quarterly Report on Form 10-Q about our expectations,
beliefs, plans, objectives, prospects, financial condition, assumptions or future events or performance are not historical facts and are forward-looking statements as that term is defined under the Federal Securities Laws. These
statements are often, but not always, made through the use of words or phrases such as believe, anticipate, should, intend, plan, will, expects,
estimates, projects, positioned, strategy, outlook, and similar words. You should read statements that contain these types of words carefully. Such forward-looking statements are subject to
a number of risks, uncertainties and other factors that could cause actual results to differ materially from what is expressed or implied in such forward-looking statements. There may be events in the future that we are not able to predict
accurately or over which we have no control. Potential risks and uncertainties include, but are not limited to, those discussed below under Risk Factors That May Affect Future Results and elsewhere in this Quarterly Report as well as
other risks and uncertainties detailed in our Annual Report on Form 10-K, filed with the Securities and Exchange Commission on February 23, 2005. We do not undertake any obligation to release publicly any revisions to such forward-looking statements
to reflect events or uncertainties after the date hereof or to reflect the occurrence of unanticipated events.



Overview



Revenues for
the quarter ended March 31, 2005 were $277.1 million, with net income of $47.1 million. During the quarter we acquired Zymed Laboratories Inc. (Zymed), a producer of pathology products, cancer and cell biology reagents and biomarkers, and general
immunochemical reagents for the life sciences research and clinical diagnostics markets.



On April 1, 2005, we acquired Dynal Biotech Holding AS (Dynal), based in Oslo, Norway. Dynal is the industry leader in magnetic bead technologies that are used in cell separation and purification, cell stimulation,
protein research, nucleic acid research and microbiology.



These recent acquisitions have introduced and will continue to enable us to offer new technology and products in our BioDiscovery segment.

the initial cloning and manipulation of DNA, to examining RNA levels and regulating gene expression in cells, to capturing, separating and analyzing proteins. These include the research tools used in reagent and kit form that simplify and improve
gene acquisition, gene cloning, gene expression, and gene analysis techniques. This segment also includes a full range of enzymes, nucleic acids, other biochemicals and reagents. These biologics are manufactured to the highest research standards and
are matched in a gene specific, validated manner (gene, orf, rnai, protein, antibodies, etc.) to ensure researchers the highest purity and scientific relevance for their experimentation. We also offer software through this segment that enables more
efficient, accelerated analysis and interpretation of genomic, proteomic and other biomolecular data for application in pharmaceutical, therapeutic and diagnostic development. The recent acquisitions of Zymed and Dynal have introduced and will
continue to enable us to offer new technology and products, such as antibodies and proteins (Zymed) and magnetic beads used for biological separation (Dynal), which is the first step in almost every biologic investigative or diagnostic process.

| | · | BioProduction. Our BioProduction product segment includes all of our cell culture products and biological testing services business. Products include sera, cell and tissue
culture media, reagents used in both life sciences research and in processes to grow cells in the laboratory, and to produce pharmaceuticals and other materials made through cultured cells. BioProduction services include testing to ensure that
biologics are free of disease-causing agents or do not cause adverse effects, characterization of products chemical structures, development of formulations for long-term stability, and validation of purification processes under regulatory
guidelines. We also manufacture biologics on behalf of clients both for use in clinical trials and for the worldwide commercial market.

Our BioDiscovery and BioProduction products are used for research purposes, and their use by our customers generally is not regulated by the United States
Food and Drug Administration (FDA) or by any comparable international organization, with several limited exceptions. Some of our BioProduction products and manufacturing sites, including some of our BioReliance subsidiarys sites, are subject
to FDA regulation and oversight and are required to comply with the Quality System Regulations, which was formerly known as current good manufacturing practice, or GMP, and is described in 21 CFR part 820. Additionally, some of these same sites and
products are intended to comply with certain voluntary quality programs such as ISO 9001.



Except for our oligonucleotide, genomics services, biologics testing, specialized manufacturing, and cell culture production businesses, which are make-to-order businesses, we principally manufacture products for
inventory and ship products shortly after the receipt of orders, and anticipate that we will continue to do so in the future. We do not currently have a significant backlog and do not anticipate building a material backlog in the future. In
addition, we rely on third-party manufacturers to supply many of our raw materials, product components, and in some cases, entire products.



Outlook



In 2005, we expect continued overall revenue growth of 16% due to acquisitions and organic growth. We expect our organic growth rate to contribute approximately 6% to 8% We believe gross margins will be affected by
the integration of acquired businesses in addition to sales volumes, competitive conditions, royalty payments on licensed technologies, the cost of raw materials, changes in average selling prices, our ability to make productivity improvements, and
foreign currency rates. We expect to see continued productivity gains in our sales and marketing expenditures as we use product specialists to support our existing customer account managers allowing us to maintain the effectiveness of our direct
selling organization while offering an ever-increasing portfolio of products. We plan on implementing programs and actions to improve our efficiency in the general and administrative area. These programs will focus in the areas of process
improvement and automation. We expect over time that these actions will reduce our general and administrative expenses as a percent of revenues. We expect research and development expense as a percent of revenues will continue to increase as we
expand our capabilities to accelerate innovation and ramp up research and development of recently acquired businesses. You should also refer to the Risk Factors section included in this Form 10-Q for further discussion of these and other risks
related to our business.

Revenues



Revenues increased by 10% for the first quarter of 2005 compared to the
first quarter of 2004. For the quarter, revenue from acquisitions and foreign currency translation accounted for 4% and 2% of the revenue increase, respectively and revenue growth contributed 4%, driven by increased volume, slightly offset by lower
average selling prices.

Gross Margin



Gross margin in the first quarter of 2005 compared to the first quarter of 2004 increased six percentage points. Included in gross margin in 2004 were
approximately $10.3 million of costs associated with products sold that were acquired as a result of a business combination. In accordance with purchase accounting rules, this acquired inventory was written-up to fair market value, and subsequently
expensed as the inventory was sold. Excluding the impact of inventory revaluations, gross margin increased 1% in the first quarter of 2005 compared to the first quarter of 2004. The increase in gross margin resulted from productivity improvements
and favorable currency exchange rates, offset by unfavorable mix and lower average selling prices.

Sales and
Marketing. For the first quarter of 2005, sales and marketing expenses increased 7% compared to the first quarter of 2004. The increase includes incremental expenses of $1.5 million from BioReliance, which was acquired during the first quarter
of 2004, and Zymed. Additionally, the increase is due to the change in foreign currency exchange rates and increased incentive compensation of $1.3 million and $0.8 million, respectively. The increase is slightly offset by a reduction in headcount,
which resulted in $0.5 million in savings. Overall, sales and marketing expenses as a percentage of revenues remained constant.



General and Administrative. For the first quarter of 2005, general and administrative expenses increased 11% compared to the first quarter of 2004.
Included in expenses in 2005 are $2.0 million of implementation costs related to outsourcing certain global functions and an additional $1.5 million in general and administrative costs from acquired companies. Additionally, the increase reflects the
change in foreign currency exchange rates and increased compensation of $0.8 million and $0.9 million, respectively. These increases were partially offset by lower legal fees of $1.5 million due to settlement of lawsuits in the first quarter of
2004, and lower bad debt expense. Overall, general and administrative expenses as a percentage of revenues remained constant.



Research and Development. The increase in research and development expenses for 2005 reflects increased headcount and higher incentive compensation
of $1.3 million, costs of $2.2 million associated with the acquisition of BioReliance, and higher research facilities costs of $1.1 million, due to the increased headcount and construction of a new science building.



Purchased Intangibles Amortization. Amortization expense for purchased
intangible assets acquired in our business combinations was $25.9 million for the first quarter of 2005 compared to $28.2 million for the first quarter of 2004. The decrease is primarily due to certain intangible assets being fully amortized during
2004.

Purchased In-Process Research and Development. In conjunction with our acquisition of Zymed in the
first quarter of 2005, we purchased in process research and development projects valued at $1.2 million that was expensed upon the acquisition date.



Interest Income. Interest income includes the loss on sale of investments of $0.9 million for the quarter ended March 31, 2005. The proceeds from
the sale of investments were used to acquire Dynal. Excluding this loss, interest income was $6.8 million in the first quarter of 2005, compared to $5.9 million in the first quarter of 2004. The increase is mainly due to portfolio mix, whereby
certain foreign investment portfolios had higher yields. Interest income in the future will be affected by changes in short-term interest rates and changes in cash balances, which may materially increase or decrease as a result of acquisitions and
other financing activities.



Interest Expense. Interest
expense was $7.3 million for the first quarter of 2005 compared to $9.5 million for the first quarter of 2004. The decrease of $2.2 million was primarily due to the redemption in March 2004 of our 51⁄2% convertible notes, which reduced interest
expense by $2.5 million. The decrease is partially offset by the issuance of our 11⁄2% convertible notes in February of 2004.



Other Income (Expense).Included in other income in the first quarter of 2005 is a $21.0 million gain on the settlement of a forward contract
related to the acquisition of Dynal. Also included in other income was a $2.7 million gain on the sale of an equity investment. Net foreign currency transaction gains were $1.9 million for the quarter ended March 31, 2005.



Provision for Income Taxes.Income taxes are determined using an
estimated annual effective tax rate, which is less than the 35% U.S. federal statutory rate, primarily because of lower tax rates in certain non-U.S. jurisdictions, export incentives and research and development tax credits available in the United
States. The Company recognizes deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of the Companys assets and liabilities.



The estimated annual effective tax rate as a percentage of pre-tax income was
30.9% for the three months ended March 31, 2005 compared with 26.8% for the year ended December 31, 2004. The marginal increase in the effective tax rate is due primarily to an expected increase in the total amount of income to be earned for the
full year 2005 and the proportion of income earned in jurisdictions having higher tax rates.



Segment Results for the First Quarter of 2005 Compared to the First Quarter of 2004



BioDiscovery Segment. BioDiscovery revenues for the first quarter of 2005 increased 6% compared to the first quarter of 2004. The increase
primarily consisted of 3% volume growth, 2% favorable foreign currency and 1% impact from acquisitions. BioDiscovery gross margin improved 2% for the first quarter of 2005 compared to the same period in 2004 mainly due to favorable currency rates
and higher royalty revenue. Operating margin of 28% for the first quarter of 2005 was consistent with the first quarter of 2004.



BioProduction Segment. BioProduction revenue for the first quarter of 2005 increased 16% over the first quarter of 2004. The increase is primarily
driven by the acquisition of BioReliance, which occurred during the first quarter of 2004 and accounted for 9% of the revenue growth in the first quarter of 2005. Changes in foreign currency exchange rates increased BioProduction revenues by 2% in
the first quarter of 2005 compared to the first quarter of 2004. BioProduction volume growth was 5% over the prior year first quarter. BioProduction gross margin improved 2% for the first quarter of 2005 compared to the first quarter of 2004. The
increase is primarily the result of improved productivity. Operating margin improved to 23% for the first quarter of 2005 compared to 21% for the first quarter of 2004, due to the increase in gross margin.



LIQUIDITY AND CAPITAL RESOURCES



Cash, cash equivalents and investments (including restricted) were $1.07
billion at March 31, 2005, a decrease of $26.5 million from December 31, 2004. The decrease was primarily due to investments of $63.2 million in acquired businesses and $11.9 million in capital expenditures, payments on long-term obligations of
$10.2 million (net of loan proceeds of $0.7 million) and unfavorable exchange rates on cash held in currencies other than the United States dollar of $17.6 million, offset by cash provided by operations of $63.0 million and proceeds from the
issuance of common stock under our stock option and employee stock purchase plans of $19.1 million.



Accounts receivable increased $14.9 million during the first quarter of 2005. The increase in accounts receivable was primarily due to the increase in
sales. Days sales outstanding were 58 days compared to 53 days at December 31, 2004 primarily due to seasonally slower collections in Europe. Inventory increased $2.9 million, primarily to support ongoing business requirements. Accounts payable and
other current liabilities decreased primarily due to the payout



20



---

of 2004 incentive compensation in the first quarter of 2005. Changes in prepaid expenses and other current assets and income taxes payable were due to timing
of payments versus when the expenses are incurred. As a result of working capital improvement programs currently being developed we expect to utilize our working capital more efficiently in the future resulting in higher inventory turnover and lower
days sales outstanding. Our working capital factors, such as inventory turnover and days sales outstanding, are seasonal, and, on an interim basis during the year, may require short-term working capital needs.



As of March 31, 2005, foreign subsidiaries in Australia, Brazil, Japan and
New Zealand had available bank lines of credit denominated in local currency to meet short-term working capital requirements. The U.S. dollar equivalent of these facilities totaled $8.7 million, of which $1.3 million was outstanding at March 31,
2005.



On April 27, 2005, the Company entered into a secured
line of credit that provides up to $250 million in borrowings at IBOR plus 0.15. The secured credit facility is collateralized by investments and matures on September 30, 2005. On April 28, 2005 the Company borrowed $124 million to repurchase $125
million of its 21⁄4% convertible subordinated notes due December 15, 2006, for less than par value. The amount available from the line of credit was $126 million upon completion of the repurchase of the convertible subordinated notes.



We believe our current cash and cash equivalents, investments, cash
provided by operations and interest income earned thereon will satisfy our working capital requirements for the foreseeable future. Our future capital requirements and the adequacy of our available funds will depend on many factors, including future
business acquisitions, future stock or note repayment or repurchases, scientific progress in our research and development programs and the magnitude of those programs, our ability to establish collaborative and licensing arrangements, the cost
involved in preparing, filing, prosecuting, maintaining and enforcing patent claims and competing technological and market developments.



We intend to continue our strategic investment activities in new product development, in-licensing technologies and acquisitions that support our
BioDiscovery and BioProduction platforms. In the event additional funding needs arise, we may obtain cash through new debt or stock issuance, or a combination of sources.



CONTRACTUAL OBLIGATIONS



During the quarter ended March 31, 2005 we assumed a $7.5 million operating lease obligation from the acquisition of Zymed. Our contractual obligations
were reduced by approximately $13.8 million during the quarter, as a result of the final payment for the Eugene, Oregon campus purchase and the sublease of our property in Bethesda, Maryland. We have no off-balance sheet arrangements as defined in
S-K 303(a)(4)(ii).



CRITICAL ACCOUNTING POLICIES



There were no significant changes in critical accounting policies or
estimates from those at December 31, 2004. For information on the recent accounting pronouncements impacting our business, see Note 1 of the Notes to Condensed Consolidated Financial Statements included in Item 1.



RISK FACTORS THAT MAY AFFECT FUTURE RESULTS



You should carefully consider the following risks, together with other
matters described in this Form 10-Q or incorporated herein by reference in evaluating our business and prospects. If any of the following risks occurs, our business, financial condition or operating results could be harmed. In such case, the trading
price of our securities could decline, in some cases significantly. The risks described below are not the only ones we face. Additional risks not presently known to us, or that we currently deem immaterial, may also impair our business operations.
Certain statements in this Form 10-Q (including certain of the following factors) constitute forward-looking statements. Please refer to the section entitled Forward-Looking Statements on this Form 10-Q for important limitations on these
forward-looking statements.



Risks Related to the Growth of Our Business



We must continually offer new products and technologies.



Our success depends in large part on continuous, timely
development and introduction of new products that address evolving market requirements and are attractive to customers. For example, prepackaged kits to perform research in particular cell lines and already-isolated genetic material only recently
have come into widespread use among researchers. We also believe that because of the initial time investment required by our customers to purchase a new product, once a customer purchases a product from a competitor, it is very difficult to regain
that customer.



21



---

These facts have led us to focus significant efforts and resources on the development and identification
of new technologies and products. As a result, we have a very broad product line and are continually looking to develop, license or acquire new technologies and products to further broaden it. If we fail to develop, license or otherwise acquire new
technologies, our customers will likely purchase products from our competitors, significantly harming our business. Once we have developed or obtained the technology, to the extent that we fail to timely introduce new and innovative products that
are accepted by our markets, we could fail to obtain an adequate return on our research and development, licensing and acquisition investments and could lose market share to our competitors, which would be difficult or impossible to regain and could
seriously damage our business. Some of the factors affecting market acceptance of our products include:



| |  |  | availability, quality and price as compared to competitive products;
| | - |  | --------------------------------------------------------------------



| |  |  | the functionality of new and existing products;
| | - |  | -----------------------------------------------



| |  |  | the timing of introduction of our products as compared to competitive products;
| | - |  | -------------------------------------------------------------------------------



| |  |  | scientists and customers opinions of the products utility and our ability to incorporate their feedback into future products;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | citation of the products in published research; and
| | - |  | ---------------------------------------------------



| |  |  | general trends in life sciences research and life science informatics software development.
| | - |  | -------------------------------------------------------------------------------------------



Failure to integrate acquired businesses into our operations successfully could adversely affect our business.



As part of our strategy to develop and identify new products and
technologies, we have made several acquisitions, and are likely to make more. Our integration of the operations of acquired businesses requires significant efforts, including the coordination of information technologies, research and development,
sales and marketing, operations, manufacturing and finance. These efforts result in additional expenses and involve significant amounts of managements time that cannot then be dedicated to other projects. Our failure to manage successfully and
coordinate the growth of the combined company could also have an adverse impact on our business. In addition, there is no guarantee that some of the businesses we acquire will become profitable or remain so. If our acquisitions do not reach our
initial expectations, we may record unexpected impairment charges. Factors that will affect the success of our acquisitions include:



| |  |  | presence or absence of adequate internal controls and/or significant fraud in the financial systems of acquired companies;
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | any decrease in customer loyalty and product orders caused by dissatisfaction with the combined companies product lines and sales and marketing practices, including price
increases;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to retain key employees;
| | - |  | ------------------------------------



| |  |  | the ability of the combined company to achieve synergies among its constituent companies, such as increasing sales of the combined companys products, achieving cost savings
and effectively combining technologies to develop new products.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Risks Related to Our Sales



We face significant
competition.



The markets for our products are very
competitive and price sensitive. Our competitors, which could include certain of our customers such as large pharmaceutical companies, have significant financial, operational, sales and marketing resources and experience in research and development.
Our competitors could develop new technologies that compete with our products or even render our products obsolete. If a competitor develops superior technology or cost-effective alternatives to our kits and other products, our business could be
seriously harmed.



The markets for certain of our products,
such as electrophoresis products, custom primers, amplification products, and fetal bovine serum, are also subject to specific competitive risks. These markets are highly price competitive. Our competitors have competed in the past by lowering
prices on certain products. If they did so again we may be forced to respond by lowering our prices. This would reduce revenues and profits. Conversely, failure to anticipate and respond to price competition may hurt our market share.



22



---

We believe that customers in our markets display a significant amount of loyalty to their initial
supplier of a particular product. Therefore, it may be difficult to generate sales to potential customers who have purchased products from competitors. Additionally, instead of using kits, there are numerous scientists making materials themselves.
To the extent we are unable to be the first to develop and supply new products, customers may buy from our competitors or make materials themselves, causing our competitive position to suffer.



There has been a trend toward industry consolidation in our markets for the
past several quarters. We expect this trend toward industry consolidation to continue as companies attempt to strengthen or hold their market positions in an evolving industry and as companies are acquired or are unable to continue operations. We
believe that industry consolidation may result in stronger competitors that are better able to compete as sole-source vendors for customers. This could lead to more variability in operating results and could have a material adverse effect on our
business.



Reduction in research and development budgets and government
funding may affect sales.



Our customers include
researchers at pharmaceutical and biotechnology companies, academic institutions, government laboratories and private foundations. Fluctuations in the research and development budgets of these researchers and their organizations could have a
significant effect on the demand for our products. Research and development budgets fluctuate due to changes in available resources, mergers of pharmaceutical and biotechnology companies, spending priorities, general economic conditions and
institutional and governmental budgetary policies. Our business could be seriously damaged by any significant decrease in life sciences research and development expenditures by pharmaceutical and biotechnology companies, academic institutions,
government laboratories or private foundations. In particular a significant portion of our sales have been to researchers whose funding is dependent upon grants from government agencies such as the U.S. National Institutes of Health (NIH). Although
the level of research funding increased significantly during the years of 1999 through 2003, increases for fiscal 2004 and 2005 were significantly lower. Government funding of research and development is subject to the political process, which is
inherently fluid and unpredictable. Other programs, such as homeland security or defense, or general efforts to reduce the federal budget deficit could be viewed by the U.S. government as a higher priority. Past proposals to reduce budget deficits
have included reduced NIH and other research and development allocations. Any shift away from the funding of life sciences research and development or delays surrounding the approval of government budget proposals may cause our customers to delay or
forego purchases of our products, which could seriously damage our business.



In recent years, the pharmaceutical industry has undergone consolidation. Additional mergers or corporate consolidations in the pharmaceutical industry could cause us to lose customers, which could have a harmful
effect on our business.



Our customers generally receive funds
from approved grants at particular times of the year, for example; as determined by the U.S. federal government. In the past, such grants have been frozen for extended periods or have otherwise become unavailable to various institutions without
advance notice. The timing of the receipt of grant funds affects the timing of purchase decisions by our customers and, as a result, can cause fluctuations in our sales and operating results.



Changing purchasing arrangements with our customers could reduce our profit margins.



Certain of our customers have developed purchasing
initiatives to reduce the number of vendors from which they purchase in order to lower their supply costs. In some cases these accounts have established agreements with large distributors, which include discounts and the distributors direct
involvement with the purchasing process. These activities may force us to supply the large distributors with our products at a discount to reach those customers. For similar reasons many larger customers, including the U.S. government, have
requested and may in the future request, special pricing arrangements, including blanket purchase agreements. These agreements may limit our pricing flexibility, which could have an adverse impact on our business, financial condition and results of
operations. Our pricing flexibility could particularly be affected with respect to our price-sensitive products, such as electrophoresis products, custom oligonucleotides (primers), amplification products, and fetal bovine serum. For a limited
number of customers we have made sales, at the customers request, through third-party Internet vendors, to whom we are required to pay commissions. If our Internet sales grow, it could have a negative impact on our gross margins.



Sales of biological and chemical defense materials subject us to certain risks.



We have launched a biodefense initiative, which depends
upon the acceptance of our products by the U.S. government and its defense contractors.



23



---

We have developed products for use in detecting exposure to biological pathogens, and have begun
marketing those products to the U.S. government and several defense contractors. If our products do not perform well, or the U.S. government changes its priorities with respect to defense against biological and chemical weapons, our sales growth
could be affected. In addition, some third parties could object to our development of biological defense products, which could have a negative impact on our company.



Risks Related to the Development and Manufacturing of Our Products



Failure to license new technologies could impair our new product development.



We believe our ability to in-license new technologies from third parties is
and will continue to be critical to our ability to offer new products and therefore our business. A significant portion of our current revenues is from products manufactured or sold under licenses from third parties. Our ability to gain access to
technologies that we need for new products and services depends in part on our ability to convince inventors and their agents or assignees that we can successfully commercialize their inventions. We cannot assure you that we will be able to continue
to identify new technologies of interest to our customers, which are developed by others. Even if we are able to identify new technologies of interest, we may not be able to negotiate a license on acceptable terms, or at all.



Loss of licensed rights could hurt our business.



A small number of our licenses do not run for the length of the underlying
patent. We may not be able to renew our existing licenses on favorable terms, or at all. If we lose the rights to a patented technology, we may need to stop selling these products and possibly other products, redesign our products or lose a
competitive advantage. While most of our licenses are exclusive to us in certain markets, potential competitors could also in-license technologies that we fail to exclusively license and potentially erode our market share for these and other
products. Our licenses also typically subject us to various economic and commercialization obligations. If we fail to comply with these obligations we could lose important rights under a license, such as exclusivity. In some cases, we could lose all
rights under a license. Loss of such rights could, in some cases, harm our business.



In addition, certain rights granted under the license could be lost for reasons out of our control. For example, the licensor could lose patent protection for a number of reasons, including invalidity of the licensed
patent, or a third party could obtain a patent that curtails our freedom to operate under one or more licenses. We do not receive indemnification from a licensor against third-party claims of intellectual property infringement.



Fluctuation in the price and supply of raw FBS could affect our business.



The supply of raw fetal bovine serum (FBS) is sometimes limited because
serum collection tends to be cyclical. In addition, any additional discovery of bovine spongiform encephalopathy, or BSE (popularly referred to as mad cow disease) in the U.S. may cause a decline in the demand for FBS supplied from the United
States. These factors can cause the price of raw FBS to fluctuate. The profit margins we achieve on finished FBS, one of our major products, have been unstable in the past because of the fluctuations in the price of raw FBS, and any increase in the
price could adversely affect those profit margins. In addition, if we are unable to obtain an adequate supply of FBS, or if we are unable to meet demand for FBS from supplies outside the U.S., we may lose market share.



Violation of government regulations or voluntary quality programs could result in loss of
revenues and additional expense.



Certain of our products
and test services are regulated by the U.S. Food and Drug Administration (FDA) as medical devices, pharmaceuticals, or biologics. As a result we must register with the FDA as both a medical device manufacturer and a manufacturer of drug products and
comply with all required regulations. Failure to comply with these regulations can lead to sanctions by the FDA such as written observations made following inspections, warning letters, product recalls, fines, product seizures and consent decrees.
Test data for use in client submissions with the FDA could be disqualified. If the FDA were to take such actions, the FDAs sanctions would be available to the public. Such publicity could adversely affect our ability to sell these regulated
products.



Additionally, some of our customers use our products
and services in the manufacturing process for their drug and medical device products, and such end products are regulated by the FDA under Quality System Regulations (QSR). Although the customer is ultimately responsible for QSR compliance for their
products, it is also the customers expectation that the materials sold to them will meet QSR requirements. We could lose sales and customers, and incur product liability claims, if our products do not meet QSR requirements.



24



---

ISO is an internationally recognized voluntary quality standard that requires compliance with a variety
of quality requirements somewhat similar to the QSR requirements. The operations of our BioProduction segments and Eugene, Oregon facilities are intended to comply with ISO 9001. Failure to comply with this voluntary standard can lead to
observations of non-compliance or even suspension of ISO certification by the certifying unit. If we lose ISO certification, this loss could cause some customers to purchase products from other suppliers.



If we violate a government mandated or voluntary quality program, we may
incur additional expense to comply with the government mandated or voluntary standards. That expense may be material, and we may not have anticipated that expense in our financial forecasts. Our financial results could suffer as a result of these
increased expenses.



Risks Related to Our Intellectual Property



Inability to protect our technologies could affect our ability to
compete.



Our success depends to a significant degree upon
our ability to develop proprietary products and technologies. When we develop such technologies, we routinely seek patent protection in the United States and abroad to the extent permitted by law. However, we cannot assure you that patents will be
granted on any of our patent applications or that the scope of any of our issued patents will be sufficiently broad to offer meaningful protection. We only have patents issued in selected countries. Therefore, third parties can make, use, and sell
products covered by our patents in any country in which we do not have patent protection. In addition, our issued patents or patents we license could be successfully challenged, invalidated or circumvented so that our patent rights would not create
an effective competitive barrier. We provide our customers the right to use our products under label licenses that are for research purposes only. The validity of the restrictions contained in these licenses could be contested, and we cannot assure
you that we would either be aware of an unauthorized use or be able to enforce the restrictions in a cost-effective manner. Additionally, the value of our patents could be negatively impacted as a result of judicial decisions or legislative changes.



If a third party claimed an intellectual property right to
technology we use, we might need to discontinue an important product or product line, alter our products and processes, defend our right to use such technology in court or pay license fees. Although we might under these circumstances attempt to
obtain a license to such intellectual property, we may not be able to do so on favorable terms, or at all. Additionally, if our products are found to infringe a third partys intellectual property, we may be required to pay damages for past
infringement, and lose the ability to sell certain products or receive licensing revenues.



Disclosure of trade secrets could aid our competitors.



We attempt to protect our trade secrets by entering into confidentiality agreements with third parties, our employees and consultants. However, these agreements can be breached and, if they are, there may not be an
adequate remedy available to us. If our trade secrets become known we may lose our competitive position.



Intellectual property litigation and other litigation could harm our business.



Litigation regarding patents and other intellectual property rights is extensive in the biotechnology industry. We are aware that patents have been
applied for and, in some cases, issued to others claiming technologies that are closely related to ours. We are currently a defendant in several court actions involving our intellectual property. As a result, and in part due to the ambiguities and
evolving nature of intellectual property law, we periodically receive notices of potential infringement of patents held by others. We may not be able to resolve these types of claims successfully in the future.



We are currently enforcing our intellectual property rights through patent
litigation in several court actions. We have incurred substantial costs, and are currently incurring substantial costs, in enforcing our intellectual property rights, primarily relating to H minus reverse transcriptase, which is the basis for our
Superscript and related product lines, and we
expect to incur such costs in the future for Superscript and other technologies. In the event of additional intellectual property disputes, we may be involved in further litigation. In addition to court actions, patent litigation could involve
proceedings before the U.S. Patent and Trademark Office or the International Trade Commission. Intellectual property litigation can be extremely expensive, and such expense, as well as the consequences should we not prevail, could seriously harm our
business. If we do not prevail in our pending patent litigation relating to H minus reverse transcriptase, we may be unable to prevent third parties from using this technology in the commercial marketplace. This could have a seriously harmful effect
on our business.



25



---

Risks Related to Our Operations



Litigation may harm our business or otherwise distract our management.



Substantial, complex or extended litigation could cause us to incur large expenditures and distract our management. For
example, lawsuits by employees, stockholders, collaborators, distributors, customers, or end-users of our products or services could be very costly and substantially disrupt our business. Disputes from time to time with such companies or individuals
are not uncommon, and we cannot assure you that we will always be able to resolve such disputes out of court or on terms favorable to us. Unexpected results could cause our financial exposure in these matters to exceed stated reserves and insurance,
requiring us to allocate additional funds and other resources to address these liabilities.



Loss of key personnel could hurt our business.



Our products and services are highly technical in nature. In general, only highly qualified and trained scientists have the necessary skills to develop and market our products and provide our services. In addition,
some of our manufacturing positions are highly technical as well. We face intense competition for these professionals from our competitors, customers, marketing partners and other companies throughout our industry. We do not generally enter into
employment agreements requiring these employees to continue in our employment for any period of time. Any failure on our part to hire, train, and retain a sufficient number of qualified professionals would seriously damage our business.
Additionally, integration of acquired companies and businesses can be disruptive, causing key employees to leave. Further, we use stock options, restricted stock, and restricted stock units/awards to provide incentive to these individuals to stay
with us and to build long-term stockholder value. If our stock price fluctuates below the exercise price of these options or reduces the value of restricted stock and restricted stock units/awards, a key employees incentive to stay is
lessened. If we were to lose a sufficient number of our key employees, including research and development scientists, and were unable to replace them or satisfy our needs for research and development through outsourcing, these losses could seriously
damage our business.



We have a significant amount of debt, which could
adversely affect our financial condition.



We have $500
million of subordinated convertible notes that are due in 2006, $350 million of senior convertible notes that are due in 2023, and $450 million of senior convertible notes due in 2024. In addition, the holders of our $350 million of senior
convertible notes have the option to require us to redeem the notes for cash at par value in August of 2010, 2013 or 2018. The holders of our $450 million senior convertible notes have the option to require us to redeem the notes for cash at par
value in February of 2012, 2017 or 2022. If we are unable to generate sufficient cash flow or otherwise obtain funds necessary to make required payments on these notes, we will be in default under the terms of the loan agreements or indentures,
which could, in turn, cause defaults under the remainder of these existing and any future debt obligations.



Even if we are able to meet our debt service obligations, the amount of debt we have could adversely affect us in a number of ways, including by:



| |  |  | limiting our ability to obtain any necessary financing in the future for working capital, capital expenditures, debt service requirements, or other purposes;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | limiting our flexibility in planning for, or reacting to, changes in our business;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | placing us at a competitive disadvantage relative to our competitors who have lower levels of debt;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | making us more vulnerable to a downturn in our business or the economy generally;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | subjecting us to the risk of being forced to refinance these amounts when due at higher interest rates; and
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | requiring us to use a substantial portion of our cash to pay principal and interest on our debt, instead of contributing those funds to other purposes such as working capital and
capital expenditures.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



We could lose the tax deduction on our
convertible senior notes due 2023 and the convertible senior notes due 2024 under certain circumstances.



We could lose some or all of the tax deduction for interest expense associated with our convertible senior notes due 2023 and the convertible senior notes
due in 2024 if, under certain circumstances, the foregoing notes are not subject to the special Treasury Regulations governing contingent payment debt instruments or the exchange of these notes is deemed to be a taxable exchange. We also could lose
the tax deduction for interest expense associated with the foregoing notes if we were to invest in non-taxable investments.



26

Risks Related to Our International Operations



International unrest or foreign currency fluctuations could adversely affect our results.



Including subsidiaries and distributors, our products are currently marketed
in approximately 70 countries throughout the world. Our international revenues, which include revenues from our non-U.S. subsidiaries and export sales from the U.S., represented 49% of our product revenues in 2004, 48% of our product revenues in
2003, and 44% of our product revenues in 2002. We expect that international revenues will continue to account for a significant percentage of our revenues for the foreseeable future. There are a number of risks arising from our international
business, including those related to:



| |  |  | foreign currency exchange rate fluctuations, potentially reducing the U.S. Dollars we receive for sales denominated in foreign currency;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the possibility that unfriendly nations or groups could boycott our products;
| | - |  | -----------------------------------------------------------------------------



| |  |  | general economic and political conditions in the markets in which we operate;
| | - |  | -----------------------------------------------------------------------------



| |  |  | potential increased costs associated with overlapping tax structures;
| | - |  | ---------------------------------------------------------------------



| |  |  | potential trade restrictions and exchange controls;
| | - |  | ---------------------------------------------------



| |  |  | more limited protection for intellectual property rights in some countries;
| | - |  | ---------------------------------------------------------------------------



| |  |  | difficulties and costs associated with staffing and managing foreign operations;
| | - |  | --------------------------------------------------------------------------------



| |  |  | unexpected changes in regulatory requirements;
| | - |  | ----------------------------------------------



| |  |  | the difficulties of compliance with a wide variety of foreign laws and regulations;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | longer accounts receivable cycles in certain foreign countries, whether cultural, due to exchange rate fluctuation or other factors;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | import and export licensing requirements; and
| | - |  | ---------------------------------------------



| |  |  | changes to our distribution networks.
| | - |  | -------------------------------------



A significant portion of our business is conducted in currencies other than the U.S. dollar, which is our reporting currency. Our recent acquisition of
Dynal Biotech Holding AS substantially increases the portion of our business that is conducted in Norwegian Kroner and the associated currency translation risk. While we attempt to hedge cash flows in these currencies, this program relies in part on
forecasts of these cash flows and the expected range of fluctuations. As a result, we cannot assure you this program will adequately protect our operating results from the full effects of exchange rate fluctuations. As a result, fluctuations between
the currencies in which we do business have caused and will continue to cause foreign currency transaction gains and losses. We cannot predict the effects of currency exchange rate fluctuations upon our future operating results because of the number
of currencies involved, the variability of currency exposures, and the volatility of currency exchange rates.



Risks Related to the Market for Our Securities



Our operating results and the market price of our stock and convertible notes could be volatile.



Our operating results and stock price have in the past been, and will continue to be, subject to quarterly fluctuations as a result of a number of
factors, including those listed in this section of this Quarterly Report and those we have failed to foresee. Our stock price and the price of our convertible notes could also be affected by any inability to meet analysts expectations, general
fluctuations in the stock market or the stocks of companies in our industry or those of our customers. Such volatility has had a significant effect on the market prices of many companies securities for reasons unrelated to their operating
performance, and has in the past led to securities class action litigation. Securities litigation against us could result in substantial costs and a diversion of our managements attention and resources, which could have an adverse effect on
our business.



Risks Related to Environmental Issues



We are subject to risks related to handling of hazardous materials and other regulations
governing environmental safety.



27



---

Our operations are subject to complex and stringent environmental, health, safety and other governmental
laws and regulations that both public officials and private individuals may seek to enforce. Our activities that are subject to these regulations include, among other things, our use of hazardous and radioactive materials and the generation,
transportation and storage of waste. While we believe we are in material compliance with these laws and regulations, we could discover that we or an acquired business is not in material compliance. Existing laws and regulations may also be revised
or reinterpreted, or new laws and regulations may become applicable to us, whether retroactively or prospectively, that may have a negative effect on our business and results of operations. It is also impossible to completely eliminate the risk of
accidental environmental contamination or injury to individuals. In such an event, we could be liable for any damages that result, which could adversely affect our business. Additionally, although unlikely, a catastrophic incident could partially or
completely shut down our research and manufacturing facilities and operations.



Furthermore, in acquiring Dexter, we assumed certain of Dexters environmental liabilities, including clean-up of several hazardous waste sites listed on the National Priority List under federal Superfund law.
Unexpected results related to the investigation and clean-up of these sites could cause our financial exposure in these matters to exceed stated reserves and insurance, requiring us to allocate additional funds and other resources to address our
environmental liabilities, which could cause a material adverse effect on our business.



Potential product liability claims could affect our earnings and financial condition.



We face a potential risk of liability claims based on our products or services. We carry product liability insurance coverage, which is limited in scope
and amount. We cannot assure you, however, that we will be able to maintain this insurance at a reasonable cost and on reasonable terms. We also cannot assure you that this insurance will be adequate to protect us against a product liability claim,
should one arise.



Some of our services include the manufacture
of biologic products to be tested in human clinical trials. We could be held liable for errors and omissions in connection with these services. In addition, we formulate, test and manufacture products intended for use by the public. These activities
could expose us to risk of liability for personal injury or death to persons using such products, although we do not commercially market or sell the products to end users. We seek to reduce our potential liability through measures such as
contractual indemnification provisions with clients (the scope of which may vary from client-to-client, and the performances of which are not secured), insurance maintained by clients and conducting certain of these businesses through subsidiaries.
Notwithstanding, we could be materially and adversely affected if we were required to pay damages or incur defense costs in connection with a claim that is outside the scope of the indemnification agreements, if the indemnity, although applicable,
is not performed in accordance with its terms or if our liability exceeds the amount of applicable insurance or indemnity. In addition, we could be held liable for errors and omissions in connection with the services we perform. We currently
maintain product liability and errors and omissions insurance with respect to these risks. There can be no assurance that our insurance coverage will be adequate or that insurance coverage will continue to be available on terms acceptable to us.



Item 3. Quantitative and Qualitative Disclosures About Market Risk



We are exposed to market risk related to changes in
foreign currency exchange rates, commodity prices, and interest rates, and we selectively use financial instruments to manage these risks. We do not enter into financial instruments for speculation or trading purposes. These financial exposures are
monitored and managed by us as an integral part of our overall risk management program, which recognizes the unpredictability of financial markets and seeks to reduce potentially adverse effects on our results.



Foreign Currency Transactions. We have operations in Europe,
Asia-Pacific and the Americas. As a result, our financial position, results of operations and cash flows can be affected by fluctuations in foreign currency exchange rates. Many of our reporting entities conduct a portion of their business in
currencies other than the entitys functional currency. These transactions give rise to receivables and payables that are denominated in currencies other than the entitys functional currency. The value of these receivables and payables is
subject to changes in exchange rates because they may become worth more or less than they were worth at the time we entered into the transaction due to changes in currency exchange rates. Both realized and unrealized gains or losses on the value of
these receivables and payables are included in the determination of net income. Realized and unrealized gains or losses on the value of financial contracts entered into to hedge the currency exchange rate exposure of these receivables and payables
are also included in the determination of net income. Net currency exchange gains recognized on business transactions, net of hedging transactions, were $22.9 million for the three months ended March 31, 2005 and are included in other income and
expense in the Condensed Consolidated Statements of Income. Transaction gains during the first quarter ended March 31, 2005 include a $21.0 million gain on a foreign currency forward contract to buy Norwegian kroner, executed for the acquisition of
Dynal, and a $2.2 million gain on a short-term intercompany loan.

Our currency exposures vary, but are primarily concentrated in the euro, British pound sterling and
Japanese yen. Historically, we have used foreign currency forward contracts to mitigate foreign currency risk on foreign currency receivables and payables. At March 31, 2005, we had $31.9 million in foreign currency forward contracts outstanding to
hedge currency risk on specific receivables and payables. These contracts, which all settle in April 2005, effectively fix the exchange rate at which these specific receivables and payables will be settled in, so that gains or losses on the forward
contracts offset the losses or gains from changes in the value of the underlying receivables and payables.



As part of our foreign currency hedging program, we hedge forecasted foreign currency cash flows. At March 31, 2005, the value of our executed forward
contracts to hedge forecasted foreign currency cash flows totaled $115.7 million. The contracts mature on various dates through 2005. The contracts increase or decrease in value prior to their maturity will be accounted for as cash flow hedges
and recorded in other comprehensive income in the Condensed Consolidated Balance Sheets. To the extent any portion of the forward contracts is determined to not be an effective hedge, the increase or decrease in value prior to the maturity will be
recorded in other income and expense in our statement of income.



Based on the cash flow hedge contracts outstanding as of March 31, 2005, a 10% decrease in the value of the dollar relative to the currencies under contract would result in an approximate $11.6 million unrealized loss. Conversely, a 10%
increase in the value of the dollar relative to the currencies under contract would result in a $11.6 million unrealized gain. Consistent with the nature of the economic hedge provided by these foreign exchange contracts, such unrealized gains or
losses would be offset by corresponding decreases or increases, respectively, in the dollar value of the future foreign currency cash flows.



Commodity Prices. Our exposure to commodity price changes relates to certain manufacturing operations that utilize certain commodities as raw
materials. We manage our exposure to changes in those prices primarily through our procurement and sales practices.



Interest Rates. Our investment portfolio is maintained in accordance with our investment policy that defines allowable investments, specifies
credit quality standards and limits the credit exposure of any single issuer. The fair value of our cash equivalents and marketable securities is subject to change as a result of changes in market interest rates and investment risk related to the
issuers credit worthiness. We do not utilize financial contracts to manage our exposure in our investment portfolio to changes in interest rates. At March 31, 2005, we had $1.07 billion in cash, cash equivalents and marketable securities, all
of which are stated at fair value. Changes in market interest rates would not be expected to have a material impact on the fair value of $646.6 million of our cash and cash equivalents at March 31, 2005, as these consisted of securities with
maturities of less than three months. A 100 basis point increase or decrease in interest rates would, however, decrease or increase, respectively, the remaining $419.3 million of our investments by approximately $3.8 million. While changes in
interest rates may affect the fair value of our investment portfolio, any gains or losses will not be recognized in our statement of income until the investment is sold or if the reduction in fair value was determined to be a permanent impairment.



As of March 31, 2005, the Company had one outstanding interest
rate swap, which swapped floating rate LIBOR payments to fixed rate payments. The current notional amount of this swap was $4.1 million. This debt was settled in April 2005.



Item 4. Controls and Procedures



The Company maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act in 1934, as
amended (the Exchange Act)) that are designed to ensure that information required to be disclosed in the Companys reports filed under the Exchange Act, is recorded, processed, summarized and reported within the time periods
specified in the SECs rules and forms, and that such information is accumulated and communicated to the Companys management, including the Companys Principal Executive Officer, Principal Financial Officer and Chief Operating
Officer, as appropriate, to allow timely decisions regarding required disclosure.



As of the end of the period covered by this report, an evaluation was carried out under the supervision and with the participation of the Companys management, including the Companys Principal Executive
Officer, Principal Financial Officer and Chief Operating Officer, of the effectiveness of the design and operation of the Companys disclosure controls and procedures as of the end of the period covered by this report (the Evaluation
Date). Based upon that evaluation, the Principal Executive Officer, Principal Financial Officer and Chief Operating Officer have concluded that the Companys disclosure controls and procedures were effective at the reasonable assurance
level as of the Evaluation Date.

have concluded that there have been no changes to the Companys internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the last fiscal quarter, that has materially affected, or are
reasonably likely to materially affect, the Companys internal control over financial reporting, other than the remedies of the deficiencies noted above and currently in process.
