INVITROGEN CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)



|1. | Basis of Presentation
|-- | ---------------------

Financial Statement Preparation

The unaudited condensed consolidated financial statements have been prepared by Invitrogen Corporation according to the rules and
regulations of the Securities and Exchange Commission (SEC), and therefore, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have
been condensed or omitted.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements for the
periods presented reflect all adjustments, which are normal and recurring, necessary to fairly state the financial position, results of operations and cash flows. These unaudited condensed consolidated financial statements should be read in
conjunction with the audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2005 filed with the Securities and Exchange Commission (SEC) on March 1, 2006.

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
| | - |  | ---------------------------



| |  |  | Unvested restricted stock
| | - |  | -------------------------

Computations for basic and diluted earnings per share are as follows:

Share-Based Compensation

The Company has ten stock option plans: the 1995, 1997, 2000, 2001, 2002 and 2004 Invitrogen Corporation stock option plans, the 1996 and 1998 NOVEX Stock
Option/Stock Issuance Plans, the Life Technologies 1995 and 1997 Long-Term Incentive Plans. During 2004, the Companys shareholders approved the 2004 Invitrogen Equity Incentive Plan (the 2004 Plan), which replaced the Companys 1997,
2000, 2001 and 2002 stock option plans (collectively, the Prior Plans). Upon approval of the 2004 Plan, all Prior Plans were frozen and a total of 5.7 million shares of the Companys common stock were reserved for granting of new awards
under the 2004 Plan. The total shares reserved for issuance under the 2004 Plan includes all options and other awards that the Company has granted that are still outstanding under the Prior Plans as of December 31, 2005. Pursuant to an
employment agreement entered in May 2003, the Company granted an option to purchase 675,000 shares of the Companys common stock to its Chief Executive Officer, which was granted outside any of the Companys option plans discussed above.

The Companys 2004 Plan permits the granting of stock options, stock appreciation rights, restricted stock awards, restricted stock
units, performance awards and deferred stock awards of up to 10.8 million shares of stock. Shares of the Companys common stock granted under the 2004 Plan in the form of stock options or stock appreciation rights are counted against the
2004 Plan share reserve on a one for one basis. Shares of the Companys common stock granted under the 2004 Plan as an award other than as an option or as a stock appreciation right are counted against the 2004 Plan share reserve on a 1.6
shares for each share of common stock basis. Stock option awards are granted to eligible employees and directors at an exercise price equal to no less than the fair market value of such stock on the date of grant, generally vest over a period of
time ranging up to four years, are exercisable in whole or in installments and expire ten years from the date of grant. Restricted stock awards and restricted stock units are granted to eligible employees and directors and represent rights to
receive shares of common stock at a future date. In addition, the Company has a qualified employee stock purchase plan (purchase rights) whereby eligible employees may elect to withhold up to 15% of their compensation to purchase shares
of the Companys stock on a quarterly basis at a discounted price equal to 85% of the lower of the employees offering price or the closing price of the stock on the date of purchase.

In December 2004, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 123 (revised 2004),
Share-Based Payment (SFAS 123R), which revised Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation (SFAS 123), supersedes APB Opinion No. 25, Accounting for Stock
Issued to Employees (APB 25) and amends Statement of Financial Accounting Standards No. 95, Statement of Cash Flows (SFAS 95). SFAS 123R establishes the accounting for share-based awards exchanged for

employee services and requires companies to expense the estimated fair value of these awards over the requisite employee service period. The provisions of
SFAS 123R are effective for the Company beginning January 1, 2006. Prior to January 1, 2006, the Company accounted for its share-based awards under the recognition and measurement principles of APB 25 and its related interpretations and
adopted the disclosure only provision of SFAS 123. Accordingly, no compensation cost was recognized for the employee stock option plan or employee stock purchase plan under the fair value recognition provisions of SFAS 123. Effective January 1,
2006, the Company adopted the provisions of SFAS 123R using the modified-prospective-transition method. Under this method, share-based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized
as expense over the employees requisite service period for all share-based awards granted, modified or cancelled as of January 1, 2006. The Company did not have any awards with market or performance conditions outstanding as of
June 30, 2006.

The Company used the Black-Scholes option-pricing model (Black-Scholes model) to value share-based employee stock
option and purchase right awards, which was also used for the Companys pro forma disclosure required under FAS 123 prior to adoption of SFAS 123R on January 1, 2006. The determination of fair value of stock-based payment awards using an
option-pricing model requires the use of certain estimates and assumptions that affect the reported amount of share-based compensation cost recognized in the Condensed Consolidated Statements of Income. Among these include the expected term of
options, the estimated forfeitures, the expected volatility of the Companys stock price, the expected dividends and the risk-free interest rate.

The expected term of share-based awards represents the weighted-average period the awards are expected to remain outstanding and is an input in the Black-Scholes model. In determining the expected term of options, the
Company considered various factors including the vesting period of options granted, employees historical exercise and post-vesting employment termination behavior, expected volatility of the Companys stock and aggregation by homogeneous
employee groups. The Company used a combination of the historical volatility of its stock price and the implied volatility of market-traded options of the Companys stock with terms of up to approximately two years to estimate the expected
volatility assumption input to the Black-Scholes model in accordance with SFAS 123R and the SECs Staff Accounting Bulletin No. 107 (SAB 107). In prior periods, the Company relied solely on the historical volatility of its stock price for
its volatility assumption input to the Black-Scholes model. The Companys decision to use a combination of historical and implied volatility was based upon the availability of actively traded options of its stock and its assessment that such a
combination was more representative of future expected stock price trends. The expected dividend yield assumption is based on the Companys expectation of future dividend payouts. The Company has never declared or paid any cash dividends on its
common stock and currently does not anticipate paying such cash dividends. However, this assumption may be subject to substantial change in the future. The Company currently anticipates that it will retain all of its future earnings for use in the
development and expansion of its business and for general corporate purposes. Any determination to pay dividends in the future will be at the discretion of the Companys Board of Directors and will depend upon the Companys results of
operations, financial condition, tax laws, and other factors as the Board of Directors, in its discretion, deems relevant. The risk-free interest rate is based upon U.S. Treasury securities with remaining terms similar to the expected term of the
share-based awards.

The underlying assumptions used to value employee stock options and purchase rights granted during the six months
ended June 30, 2006 were as follows:

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 permitted under APB 25. As a result, $2.1 million of these excess tax benefits that were previously reported as net operating cash flows are now reported as net
financing cash flows for the six months ended June 30, 2006.

The Company is required to estimate forfeitures at the time of grant and
revise those estimates in subsequent periods on a cumulative basis in the period the estimated forfeiture rate changes. The Company considered its historical experience of pre-vesting option forfeitures as the basis to arrive at its estimated
pre-vesting option forfeiture rate of 9% per year for the six months ended June 30, 2006. All option awards, including those with graded vesting, were valued as a single award with a single average expected term and are amortized on a
straight-line basis over the requisite service period of the awards, which is generally the vesting period. At June 30, 2006, there was $67.3 million remaining in unrecognized compensation cost related to employee stock options (including stock
options assumed in business combinations), which is expected to be

recognized over a weighted average period of 2 years. No compensation cost was capitalized in inventory during the six months ended June 30, 2006 as the
amounts included were not material.

Total share-based compensation expense for employee stock options (including stock options assumed in
business combinations) and purchase rights recognized for the three and six months ended June 30, 2006 is comprised of the following:

Restricted stock units represent a right to receive shares of common stock at a future date determined in
accordance with the participants award agreement. There is no exercise price and no monetary payment is required for receipt of restricted stock units or the shares issued in settlement of the award. Instead, consideration is furnished in the
form of the participants services to the Company. Restricted stock units generally vest over three to four years. Compensation cost for these awards is based on the estimated fair value on the date of grant and recognized as compensation
expense on a straight-line basis over the requisite service period. Pre-vesting forfeitures were estimated to be approximately 0% for the six months ended June 30, 2006. For the three and six months ended June 30, 2006, the Company
recognized $1.0 million and $2.3 million, respectively, in share-based compensation cost related to these restricted stock unit awards. At June 30, 2006, there was $12.3 million remaining in unrecognized compensation cost related to these
awards, which is expected to be recognized over a weighted average period 2.3 years.

The weighted average grant date fair value of
restricted stock units granted during the six months ended June 30, 2006 was $66.95. A summary of restricted stock activity for the six months ended June 30, 2006 is presented below:

During 2004 and 2003, the Company issued 20,000 and 155,000 shares of restricted stock awards,
respectively, with a weighted average grant date fair value of $72.77 for issuances during 2004 and $49.34 for issuances during 2003 to certain executive officers and key employees. The awards generally vest over four years. Compensation cost for
these restricted stock awards is based on the estimated fair value on the date of grant and recognized as compensation expense on a straight-line basis over the requisite service period. Pre-vesting forfeitures were estimated to be approximately 0%
for the six months ended June 30, 2006. For the three and six months ended June 30, 2006, the Company recognized $0.5 million and $1.0 million, respectively, in share-based compensation cost related to these restricted stock awards. At

Prior to adopting the provisions of SFAS 123R, the Company accounted for its employee stock option plans and employee stock purchase plan under the
recognition and measurement principles of APB 25 and the disclosure only provisions of 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

In February 2006, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 155, Accounting for
Certain Hybrid Financial Instruments, (SFAS 155) which amends Statement of Financial Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities, (SFAS 133) and Statement of Financial Accounting
Standards No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities, (SFAS 140). SFAS 155 simplifies the accounting for certain derivatives embedded in other financial instruments by
allowing them to be accounted for as a whole (eliminating the need to bifurcate the derivative from its host) if the holder elects to account for the whole instrument on a fair value basis. SFAS 155 also clarifies and amends certain other provisions
of SFAS 133 and SFAS 140. SFAS 155 is effective for all financial instruments acquired, issued or subject to a remeasurement event occurring in fiscal year beginning after September 15, 2006. Earlier adoption is permitted, provided the Company
has not yet issued financial statements, including for interim periods, for that fiscal year. The Company does not believe that the adoption of this statement will have a material impact on its financial condition, consolidated results of operations
or cash flows.

In June 2006, the FASB issued FASB Interpretation No. (FIN) 48, Accounting for Uncertainty in Income TaxesAn
Interpretation of FASB Statement No. 109,which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48
will be effective for fiscal years beginning after December 15, 2006, which is the Companys fiscal year 2007. The Company has not yet evaluated the potential impact of adopting FIN 48 on its consolidated financial statements.

Reclassifications

Certain
reclassifications of prior year amounts have been made to conform with the current year presentation.

Goodwill and Other Intangible Assets

The $32.0 million increase in goodwill on the condensed consolidated balance sheets from December 31, 2005 to June 30, 2006 was the result of
$11.9 million in adjustments to amounts recorded previously for prior year acquisitions as we continue to modify estimated fair values of assets acquired, liabilities assumed or costs of the transaction and $20.1 million in foreign currency
translation. The adjustments were primarily related to additional payments made for the achievement of certain development milestones and additional reserves for certain contingent obligations and the termination and relocation of certain employees
to other sites.

Intangible assets consisted of the following:

Dynal Acquisition

On April 1, 2005, the Company acquired all of the outstanding shares of common stock and stock options of Dynal Biotech Holding AS (Dynal). Based
in Oslo, Norway, Dynal is the industry leader in magnetic bead technologies used in cell separation and purification, cell stimulation, protein research, nucleic acid research and microbiology. The primary reason for the acquisition was to leverage
Dynals technologies across the Companys broad product portfolio. This combination has applications in numerous areas of research, including stem cell and cell therapy applications, as well as in products that support molecular
diagnostics, and other key areas of research. The Company has continued Dynals operations as part of its BioDiscovery business segment.

As of June 30, 2006, the final purchase price allocation is shown below:



|                                                                           |  |   |

|                                                                           |  |   |        

Purchased intangibles are being amortized over a weighted average life of 8 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.

As part
of the integration of the business, the Company has established a reserve for the termination and relocation of certain employees to other sites. At June 30, 2006, the Company had $0.9 million remaining in accrued expenses and other current
liabilities in the Condensed Consolidated Balance Sheets related to this integration. For the six months ended June 30, 2006, the Company made payments of approximately $0.4 million related to severance charges that had been accrued for
acquisition and business integration costs.

Business Consolidation Costs

The Company continues to integrate recent acquisitions into its operations and recorded approximately $5.4 million for the six months ended June 30,
2006 related to these efforts. These expenses relate primarily to the severance of employees and other costs associated with consolidation.



|5. | Segment Information
|-- | -------------------

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.

Segment information is as follows:

During the six months ended June 30, 2006, the Company repurchased $55.1 million of its
21/4% Convertible Subordinated Notes due 2006 for less than par value. The repurchase did not have a material
impact on the consolidated statement of operations.



|7. | Lines of Credit
|-- | ---------------

On January 9, 2006, the
Company entered into a syndicated $250 million senior secured credit facility (the Credit Facility) with Bank of America, N.A. Amounts borrowed under the Credit Facility are secured by substantially all of the assets of the Company, including equity
interests in certain of the Companys subsidiaries. Additionally, the Credit Facility is guaranteed by certain subsidiaries of the Company. Interest rates on outstanding borrowings are determined by reference to LIBOR or to an alternate base
rate, with margins determined based on changes in the Companys leverage ratio. Under the terms of the Credit Facility, the Company may request that the aggregate amount available be increased by $100 million of additional financing, subject to
certain conditions having been met, including the availability of additional lender commitments. The Credit Facility contains various representations, warranties, affirmative, negative and financial covenants, and conditions of default customary for
financings of this type. The Company currently anticipates using the proceeds of the Credit Facility for the purpose of general working capital and capital expenditures, and the Credit Facility will terminate and all amounts outstanding under it
will be due and payable in full on January 6, 2011. At June 30, 2006, no amounts related to this credit facility were outstanding.

At June 30, 2006, several of the Companys foreign subsidiaries had available bank lines of credit denominated in local currency to meet short-term working capital requirements. The credit facilities bear interest at fixed rates,
the respective banks prime rate, the London LIBOR rate, the Norwegian NIBOR rate and the Japan TIBOR rate (a weighted average rate of 3.10% at June 30, 2006). Under these lines of credit, the U.S. dollar equivalent of these facilities
totaled $11.7 million, of which $0.5 million was outstanding at June 30, 2006. There were no parent company guarantees associated with these facilities.



|8. | Commitments and Contingencies
|-- | -----------------------------

Operating Leases

During the first quarter of 2006, the Company terminated an existing operating lease and entered into a new operating lease
agreement for the same property for one of its office and manufacturing facilities. The new lease agreement expires in 2022 and provides for escalating rental payments with the option to renew extending through 2038. These transactions resulted in
an additional net increase to rent expense of $0.7 million for the remainder of fiscal 2006, $1.2 million for each of the fiscal years 2007, 2008, 2009 and 2010, and $49.2 million for fiscal years thereafter.

---

Letters of Credit

The Company had outstanding letters of credit totaling $9.8 million at June 30, 2006, of which $4.8 million was to support liabilities associated with the Companys self-insured workers compensation
programs and $5.0 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 June 30, 2006, future employment contract commitments for such key executives were approximately $9.0 million for the remainder of fiscal year 2006 and approximately $2.2 million for fiscal year 2007.

Contingent Acquisition Obligations

Pursuant to the purchase agreements for certain prior year 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 $78.3 million based upon certain percentages of future gross sales of the acquired companies could be required through 2007. Additional payments of $9.0 million could be required of the Company based upon the achievement of
certain development milestones through 2008. For the six months ended June 30, 2006, $8.4 million and $21.9 million of contingent payments have been earned and paid, respectively, for research and development milestones. No contingent payments
have been earned for operating results to date.

In addition, the purchase agreement for one of the prior year acquisitions may require the
Company to make additional contingent cash payments based on percentages of future gross sales of the acquired company through 2009. The purchase agreement does not limit the payment to a maximum amount. The Company will account for any such
contingent payments as an addition to the purchase price of the acquired company. No contingent payments have been earned as of June 30, 2006.

Environmental Liabilities

The Company assumed certain environmental exposures as a result of the merger with Dexter
Corporation in 2000 and recorded reserves to cover estimated environmental clean-up costs. The environmental reserves, which are not discounted, were $7.7 million at June 30, 2006, and include current reserves of $0.7 million, which are
estimated to be paid during this fiscal year, and long-term reserves of $7.0 million. In addition, the Company has an insurance policy to cover 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
June 30, 2006.

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 June 30, 2006 with respect
to these matters cannot be ascertained, the Company believes that any resulting liability should not materially affect its condensed consolidated financial statements.

|9. | Pension Plans and Postretirement Health and Benefit Program
|-- | -----------------------------------------------------------

The Company has several defined benefit pension plans covering its U.S. employees and employees in several 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 and six months ended June 30, 2006 and 2005 were as follows:

|10. | Income Taxes
|--- | ------------

Income taxes are determined using an
estimated annual effective tax rate. The provision for income taxes is less than the 35% U.S. federal statutory rate primarily due to lower tax rates in certain non-U.S. jurisdictions, export and domestic production incentives, and
research and development tax credits available from various state jurisdictions in the United States. The statutory provisions allowing the Federal research and development tax credit in the United States have expired but are
expected to be renewed. The inability to utilize the Federal research and development credits had a 1% to 2% negative impact on our annual effective tax rate.



|11. | Subsequent Event
|--- | ----------------

In July 2006, the Board approved
a program authorizing management to repurchase up to $500 million of common stock over the next three years.

|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 under Risk Factors That May Affect Future Results detailed in our Annual
Report on Form 10-K, filed with the Securities and Exchange Commission on March 1, 2006. 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 six months ended June 30, 2006 were $622.6 million, with net income of $38.9 million. In March 2006, we acquired Xcytes T cell expansion technology, known as the Xcellerate
Process. The acquired assets included intellectual property, clinical data generated by Xcyte in the course of six clinical trials of its lead product, Xcellerated T Cells, as well as raw materials and equipment. This acquisition represents a
cornerstone in a broader effort to substantially increase our offering to customers working within immunology.

Our Business and Operating Segments

We are a leading developer, manufacturer and marketer of research tools in reagent, kit and high throughput application forms to
customers engaged in life sciences research, drug discovery, diagnostics and the commercial manufacture of biological products. Additionally we are a leading supplier of sera, cell and tissue culture media and reagents used in life sciences
research, as well as in processes to grow cells in the laboratory and produce pharmaceuticals and other high valued proteins.

We conduct
our business through two principal segments:



| |  |  | BioDiscovery.Our BioDiscovery product segment includes our 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. 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.

| |  |  | BioProduction. Our BioProduction product segment includes all of our Gibco cell culture products and BioReliance services. 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. 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 the second quarter of 2006, we lowered
our expected overall revenue growth rate range to 5% to 9% for the full year of 2006. We believe gross margins will be affected by sales mix and volume, the addition of acquired businesses, 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 add
product specialists to support our existing customer account managers, allowing us to increase the effectiveness of our direct selling organization as we expand our product portfolio. We will continue to implement 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 to continue to invest in targeted research and development efforts as we expand our capabilities to accelerate innovation.

CRITICAL ACCOUNTING
POLICIES

Other than the adoption of Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based
Payments, as discussed below, there were no significant changes in critical accounting policies or estimates from those at December 31, 2005. For additional information on the recent accounting pronouncements impacting our business, see
Note 1 of the Notes to Condensed Consolidated Financial Statements included in Item 1.

Share-Based Compensation.Under our 2004 Equity
Incentive Plan (the 2004 Plan), we grant share-based awards to eligible employees and directors to purchase shares of our common stock. In addition, we have a qualified employee stock purchase plan in which eligible employees may elect to withhold
up to 15% of their compensation to purchase shares of our common stock on a quarterly basis at a discounted price equal to 85% of the lower of the employees offering price or the closing price of the stock on the date of purchase. The benefits
provided by these plans qualify as share-based compensation under the provisions of Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (SFAS 123R), which requires us to recognize compensation
expense based on their estimated fair values determined on the date of grant for all share-based awards granted, modified or cancelled as of January 1, 2006 (the effective date). Prior to the effective date, we did not recognize any
compensation cost in our income statements for share-based awards granted with an option price equal to the fair market value of the our common stock on the date of grant or employee stock purchase rights as we accounted for them under the
recognition and measurement principles of APB Opinion No. 25, Accounting for Stock Issued to Employees(APB 25) and its related interpretations and adopted the disclosure only provisions of Statement of Financial Accounting Standards
No. 123, Stock-Based Compensation (SFAS 123).

We adopted SFAS 123R on January 1, 2006 using the
modified-prospective-transition method. Under this method, share-based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized as expense over the employees requisite service period.
Prior periods are not revised for comparative purposes. For the three months ended June 30, 2006, we recognized $10.7 million, $1.0 million and $0.5 million of compensation expense for employee stock options (including stock options assumed in
business combinations) and purchase rights, restricted stock units and restricted stock awards, respectively. For the six months ended June 30, 2006, we recognized $21.0 million, $2.3 million and $1.0 million of compensation expense for
employee stock options (including stock options assumed in business combinations) and purchase rights, restricted stock units and restricted stock awards, respectively. At June 30, 2006, there was $67.3 million, $12.3 million and $2.3 million
remaining in unrecognized compensation cost related to employee stock options, restricted stock units and restricted stock awards, respectively, which are expected to be recognized over a weighted average period of 2.0 years, 2.3 years and 1.25
years, respectively.

We estimate the fair value of share-based awards on the date of grant using the Black-Scholes option-pricing method
(Black-Scholes method), which was also used for the pro forma information required to be disclosed under FAS 123. The determination of fair value of share-based awards using an option-pricing model requires the use of certain estimates and
assumptions that affect the reported amount of share-based compensation cost recognized in our Condensed Consolidated



20



---

Statements of Income. Among these include estimates of the expected term of share-based awards, expected volatility of our stock price, expected dividends
and the risk-free interest rate. These estimates and assumptions are highly subjective and may result in materially different amounts should circumstances change and we employ different assumptions in our application of FAS 123R in future periods.

For share-based awards issued during the six months ended June 30, 2006, we estimated the expected term by considering various
factors including the vesting period of options granted, employees historical exercise and post-employment termination behavior and aggregation by homogeneous employee groups. Our estimated volatility was derived using a combination of our
historical stock price volatility and the implied volatility of market-traded options of our common stock with terms of up to approximately two years. Our decision to use a combination of historical and implied volatility was based upon the
availability of actively traded options of our common stock and our assessment that such a combination was more representative of future expected stock price trends. We have never declared or paid any cash dividends on our common stock and currently
do not anticipate paying such cash dividends. We currently anticipate that we will retain all of our future earnings for use in the development and expansion of our business and for general corporate purposes. Any determination to pay dividends in
the future will be at the discretion of our Board of Directors and will depend upon our results of operations, financial condition, tax laws, and other factors as the Board of Directors, in its discretion, deems relevant. The risk-free interest rate
is based upon U.S. Treasury securities with remaining terms similar to the expected term of the share-based awards.

Revenues

Revenues increased by $7.2 million or 2.3% for the second quarter of 2006 compared to the second quarter of 2005. Increased pricing accounted for $4.1 million or 1%, which was partially offset by foreign currency
translation of $1.0 million or less than one percent. The remaining $4.1 million increase was due to higher royalty revenue of $1.1 million and the impact of acquisitions, partially offset by decreased volume.

Gross Profit

Gross profit increased by $12.5
million or 7.0% for the second quarter of 2006 compared to the second quarter of 2005. Included in gross profit for the second quarters of 2006 and 2005 was approximately $1.8 million and $11.2 million, respectively, of costs associated with the
write-up of acquired inventory to fair market value 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.
The impact of lower inventory revaluation costs increased our overall gross margin by approximately three percentage points in the second quarter of 2006 compared to the second quarter of 2005.

Sales and Marketing. For the second
quarter of 2006, sales and marketing expenses increased $7.3 million or 13% compared to the second quarter of 2005. Acquisitions accounted for $2.4 million of incremental expenses in 2006, partially offset by $0.1 million from foreign currency
translation. The remaining $5.0 million increase was mainly due to $5.2 million in increased salaries and commissions and $1.3 million from share-based compensation due to the adoption of FAS 123R, partially offset by a $1.3 million in lower
incentive compensation and a decrease of $0.2 million in other operating expenses. Overall, sales and marketing expenses as a percentage of revenues increased two percentage points mainly due to the reasons noted above.

General and Administrative. For the second quarter of 2006, general and administrative expenses increased $9.8 million or 31%
compared to the second quarter of 2005. Acquisitions accounted for $1.8 million of incremental expenses in 2006, partially offset by $0.1 million from foreign currency translation. The remaining $8.1 million increase was mainly due to $7.6 million
from share-based compensation due to the adoption of FAS 123R, $1.3 million in salaries and wages, and $1.3 million in other operating expenses, partially offset by a $2.1 million in lower incentive compensation. Overall, general and administrative
expenses as a percentage of revenues increased three percentage points mainly due to the reasons noted above.

Research and
Development. Research and development expenses for the second quarter of 2006 increased $2.3 million or 9% compared to the second quarter of 2005. Acquisitions accounted for $1.5 million of incremental research and development
expenses in 2006, partially offset by $0.1 million from foreign currency translation. The remaining $0.9 million increase was mainly due to $1.1 million from share-based compensation due to the adoption of FAS 123R, partially offset by a reduction
of $0.2 million in other operating expenses, including a $1.1 million in lower incentive compensation.

Purchased Intangibles
Amortization. Amortization expense related to purchased intangible assets acquired in our business combinations was $29.5 million for the second quarter of 2006 compared to $29.9 million for the second quarter of 2005. The $0.4
million decrease is due to a decrease in intangible assets being amortized due to the sale of a business operation,

partially offset by a greater amount of intangible assets acquired through acquisitions being amortized in the second quarter of 2006 compared to the second
quarter of 2005.

Business Consolidation Costs. Business consolidation costs for the quarter ended June 30, 2006
were $3.3 million and represent costs associated with our efforts to realign our business and consolidation of certain facilities. These costs consisted mainly of termination benefits of certain employees involuntarily terminated. We expect to
continue to incur business consolidation costs in 2006 as we further consolidate operations and facilities.

Interest
Income. Interest income was $7.9 million for the second quarter of 2006, compared to $5.1 million for the second quarter of 2005. The increase is mainly due to $0.7 million in interest income received as a part of a legal settlement
related to past patent infringement, as well as higher interest rates in the second quarter of 2006 compared to the second quarter of 2005.

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 $8.1 million for the second quarter of 2006 compared to $7.8 million for the second quarter
of 2005. The $0.3 million increase was mainly due to a higher average balance of our convertible debt in the second quarter of 2006 compared to the second quarter 2005 as a result of the issuance of our 31/4% convertible notes in June 2005. The increase was slightly offset by the partial redemption of our 21/4% convertible notes in the fourth quarter of 2005 and the first and second quarters of 2006.

Other income, net.Other income, net was $2.0 million in the second quarter of 2006 compared to $0.2 million in the second quarter
of 2005. Included in the 2006 amount is $1.3 million from the sale of a business operation and $0.9 million received as a part of a legal settlement related to past patent infringement.

Provision for Income Taxes.The estimated annual effective tax rate as a percentage of pre-tax income was 28.8 % for
the second quarter of 2006 compared with 27.4% for the second quarter of 2005. The increase in the effective tax rate is due primarily to the adoption of Statement of Financial Accounting Standards No. 123 (revised 2004),
Share-Based Payments, the expiration of federal research and development tax credits and the sale of a business operation which is considered a discreet event in the second quarter of 2005, partially offset by an increase in the
proportion of income earned in jurisdictions having lower effective tax rates than the U.S.

Segment Results for the Second Quarter of 2006 Compared to
the Second Quarter of 2005

BioDiscovery Segment. BioDiscovery revenues for the second quarter of 2006 increased $19.3 million or
10% compared to the second quarter of 2005. The increase was mainly driven by $13.7 million from acquisitions and increased volume, $4.8 million from increases in pricing and higher royalties of $1.1 million, partially offset by $0.3 million from
foreign currency translation. BioDiscovery gross margin for the second quarter of 2006 decreased 1% to 70% compared to the second quarter of 2005 primarily due to lower margin product being sold in connection with acquired companies. BioDiscovery
operating margin was 25% for the second quarter of 2006 which is consistent with the second quarter of 2005.

BioProduction Segment.
BioProduction revenues for the second quarter of 2006 decreased $12.1 million or 10% compared to the second quarter of 2005. The decrease was mainly driven by a decrease in volume of $10.9 million which was based on a decline in sera and cell
culture media sold to production customers, as well as the sale of a business operation in the second quarter of 2006. BioProduction gross margin for the second quarter of 2006 decreased 2% to 46% compared to the second quarter of 2005. The decrease
was mainly driven by the decreased volume. BioProduction operating margin decreased by 7% to 18% for the second quarter of 2006 compared to the second quarter of 2005.

Revenues

Revenues increased by $39.1 million or 7% for the first six months of 2006 compared to the first six months of 2005. Acquisitions accounted for $45.8 million or 8%. Foreign currency translation decreased revenues by
$10.0 million or 2%. The remaining $3.3 million increase was mainly due to increased volume and pricing in the BioDiscovery segment, partially offset by decreased pricing and volume in the BioProduction segment. See Segment Results below
for further information.

Gross Profit

Gross profit increased by $31.5 million or 9% for the first six months of 2006 compared to the first six months of 2005. Included in gross profit for the first six months of 2006 and 2005 was approximately $4.1 million and $11.8 million,
respectively, of costs associated with the write-up of acquired inventory to fair market value 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. The impact of these inventory revaluations increased our overall gross margin by approximately one percentage point in the first six months of 2006 compared to approximately two percentage points in
the first six months of 2005.

|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Sales and Marketing. For the first six months of 2006, sales and marketing
expenses increased $19.0 million or 18% compared to the first six months of 2005. Acquisitions accounted for $8.5 million of incremental expenses in 2006, partially offset by $0.4 million from foreign currency translation. The remaining $10.9
million increase was mainly due to $9.9 million in increased salaries and commissions, $2.5 million from share-based compensation due to the adoption of FAS 123R, and $1.5 million in other operating expenses, partially offset by a $3.0 million
reduction in incentive compensation. Overall, sales and marketing expenses as a percentage of revenues increased two percentage points mainly due to the reasons noted above.

General and Administrative. For the first six months of 2006, general and administrative expenses increased $19.2 million or 31%
compared to the first six months of 2005. Acquisitions accounted for $6.2 million of incremental expenses in 2006, partially offset by $1.4 million from foreign currency translation. The remaining $14.4 million increase was mainly due to $14.9
million from share-based compensation due to the adoption of FAS 123R and a $0.5 million decrease in other operating expenses. Overall, general and administrative expenses as a percentage of revenues increased two percentage points mainly due to the
reasons noted above.

Research and Development. Research and development expenses for the first six months of 2006
increased $10.0 million or 22% compared to the first six months of 2005. Acquisitions accounted for $6.9 million of incremental research and development expenses in 2006, partially offset by $0.6 million from foreign currency translation. The
remaining $3.7 million increase was mainly due to $2.1 million from share-based compensation due to the adoption of FAS 123R and a $1.6 million increase in other operating expenses.

Purchased Intangibles Amortization. Amortization expense related to purchased intangible assets acquired in our business
combinations was $59.4 million for the first six months of 2006 compared to $55.8 million for the first six months of 2005. The $3.6 million increase is primarily due to a greater amount of intangible assets acquired through acquisitions being
amortized in the 2006 compared to 2005.

Business Consolidation Costs. Business consolidation costs for the six months ended
June 30, 2006 were $5.4 million and represent costs associated with our efforts to realign our business and consolidation of certain facilities. These costs consisted mainly of termination benefits of certain employees involuntarily terminated.
We expect to continue to incur business consolidation costs in 2006 as we further consolidate operations and facilities.

Interest
Income. Interest income was $14.4 million for the first six months of 2006, compared to $11.0 million for the first six months of 2005. The increase is mainly due to higher interest rates in 2006 compared to 2005.

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 $16.5
million for the first six months of 2006 compared to $15.0 million for the first six months of 2005. The $1.5 million increase was mainly due to a higher average balance of our convertible debt in 2006 compared to 2005 as a result of the issuance of
our 31/4% convertible notes in June 2005. The increase was slightly offset by the partial redemption of our
21/4% convertible notes in the fourth quarter of 2005 and the first and second quarters of 2006.

Other income, net.Other income, net was $2.5 million in the first six months of 2006 compared to $25.8
million in the first six months of 2005. Included in 2005 was a $21.0 million gain on the settlement of a forward contract related to the acquisition of Dynal and a $2.8 million gain on the sale of an equity investment.

Provision for Income Taxes.The estimated annual effective tax rate as a percentage of pre-tax income was 29.6 % for
the first six months of 2006 compared with 30.1% for the first six months of 2005. The decrease in the effective tax rate is due primarily to an increase in the proportion of income earned in jurisdictions having lower effective tax
rates than the U.S., offset by the adoption of Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payments, and the expiration of federal research and development tax credits.

Segment Results for the First Six Months of 2006 Compared to the First Six Months of 2005

BioDiscovery Segment. BioDiscovery revenues for the first six months of 2006 increased $60.4 million or 17% compared to the first six months of
2005. The increase was mainly driven by $45.8 million from acquisitions and $19.7 million from increases in volume and pricing, which were partially offset by foreign currency translation of $5.5 million. BioDiscovery gross margin for the first six
months of 2006 decreased 1% to 70% compared to the first six months of 2005. BioDiscovery operating margin was 25% for the first six months of 2006 compared to 26% for the first six months of 2005.

BioProduction Segment. BioProduction revenues for the first six months of 2006 decreased $21.3 million or 9% compared to the first six months of
2005. The decrease was primarily due to declines in volume and pricing of $16.9 million due to declines in sera and cell culture media sold to production customers, the sale of a business operation in the second quarter of 2006 and $4.4 million in
foreign currency translation. BioProduction gross margin for the first six months of 2006 decreased 1% to 47% compared to the first six months of 2005. The decrease was mainly driven by the decreased volume. BioProduction operating margin decreased
by 4% to 20% for the first six months of 2006 compared to the first six months of 2005.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $600.3 million at June 30, 2006, an increase of $165.0 million from December 31, 2005 primarily due to cash
provided from operating activities of $57.4 million, cash provided by investing activities of $136.1 million and favorable impact of foreign currency of $7.1 million, partially offset by cash used in financing activities of $35.6 million.

Operating activities provided net cash of $57.4 million during the second quarter of 2006 primarily from our net income of
$38.9 million and net non-cash charges of $73.2 million. Net changes in operating assets and liabilities reduced cash from operating activities by $54.7 million. The decrease was mainly due to a $21.8 million decrease in accrued
expenses and other liabilities primarily a result of payment of our 2005 incentive compensation, a $10.5 million increase in accounts receivable, a $21.1 million increase in inventories primarily due to timing of sera collection, and a $16.0 million
decrease in accounts payable primarily due to timing of when seasonal payments were made. These items were partially offset by a $7.7 million increase in income taxes payable primarily due to an increase in our income tax provision and a
$7.0 million decrease in prepaid expenses and other assets.

As a result of working capital improvement programs, 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



26



---

turnover and days sales outstanding are seasonal, and on an interim basis during the year, may require an influx of short-term working capital.

On January 9, 2006, we entered into a syndicated $250 million senior secured credit facility (the Credit Facility) with Bank of America, N.A.
Interest rates on outstanding borrowings are determined by reference to LIBOR or to an alternate base rate, with margins determined based on changes in our leverage ratio. Under the terms of the Credit Facility, we may request that the aggregate
amount available be increased by $100 million of additional financing, subject to certain conditions having been met, including the availability of additional lender commitments. The Credit Facility contains various representations, warranties,
affirmative, negative and financial covenants, and conditions of default customary for financings of this type. We currently anticipate using the proceeds of the Credit Facility for the purpose of general working capital and capital expenditures,
and the Credit Facility will terminate and all amounts outstanding under it will be due and payable in full on January 6, 2011. See Note 7 of the Notes to Condensed Consolidated Financial Statements.

As of June 30, 2006, several of the Companys foreign subsidiaries 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 $11.7 million, of which $0.5 million was outstanding at June 30, 2006.

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 six months ended
June 30, 2006, we terminated an existing operating lease and entered into a new operating lease agreement for the same property for one of our office and manufacturing facilities. The new lease agreement expires in 2022 and provides for
escalating rental payments with the option to renew extending through 2038. See Note 8 to our Condensed Consolidated Financial Statements. We did not enter into any other significant contractual obligations during the six months ended June 30,
2006. We have no significant contractual obligations not fully recorded on our Condensed Consolidated Balance Sheets or fully disclosed in the Notes to our Condensed Consolidated Financial Statements. We have no off-balance sheet arrangements as
defined in S-K 303(a)(4)(ii).



|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 losses recognized on business transactions, net of hedging transactions, were $0.4 million for the six months ended June 30, 2006 and are included in other income and expense in the Condensed Consolidated
Statements of Income.

Our currency exposures vary, but are primarily concentrated in the euro, British pound sterling, Norwegian kroner
and Japanese yen. Historically, we have used foreign currency forward contracts to mitigate foreign currency risk on foreign currency receivables and payables. At June 30, 2006, we had $9.4 million in foreign currency forward contracts
outstanding to hedge currency risk on specific receivables and payables. These contracts, which all settle in July 2006, effectively fix the



27



---

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.

In addition to hedging the value of our foreign currency
receivables and payables, our foreign currency-hedging program includes hedging of forecasted foreign currency cash flows. The increase or decrease in value of forward contracts to hedge forecasted foreign currency cash flows prior to their maturity
are 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 are recorded in other income and expense in the Condensed Consolidated Statements of Income. At June 30, 2006, we had $49.8 million in net forecasted foreign currency cash flow hedges.

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 June 30, 2006, we had $728.8 million 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 $600.3 million of our cash and cash equivalents at June 30, 2006, 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 $128.5 million of our investments by approximately $0.4 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.



|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 and Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

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

In addition, the Principal Executive Officer and Principal Financial Officer 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.
