        GENZYME CORPORATION AND SUBSIDIARIES

        Notes to Unaudited, Consolidated Financial Statements

        1.    Description of Business

                We are a global biotechnology company dedicated to making a major impact on the lives of people with serious diseases. Our broad product and service portfolio is focused on rare disorders, renal diseases, orthopaedics, organ transplant, and diagnostic and predictive testing.testing, and cancer. We are organized into fivesix financial reporting units, which we also consider to be our reporting segments:

          Renal, which develops, manufactures and distributes products that treat patients suffering from renal diseases, including chronic renal failure. The unit derives substantially all of its revenue from sales of RenagelRenagel/Renvela (including sales of bulk sevelamer) and Hectorol;

          Therapeutics, which develops, manufactures and distributes therapeutic products, with an expanding focus on products to treat patients suffering from genetic diseases and other chronic debilitating diseases, including a family of diseases known as lysosomal storage disorders, or LSDs, and other specialty therapeutics, such as Thyrogen. The unit derives substantially all of its revenue from sales of Cerezyme, Fabrazyme, Myozyme, Aldurazyme and Thyrogen;

          Transplant, which develops, manufactures and distributes therapeutic products that address pre-transplantation, prevention and treatment of graft rejection in organ transplantation and other hematologic and auto-immune disorders. The unit derives substantially all of its revenue from sales of Thymoglobulin;

          Biosurgery, which develops, manufactures and distributes biotherapeutics and biomaterial-based products, with an emphasis on products that meet medical needs in the orthopaedics and broader surgical areas. The unit derives substantially all of its revenue from sales of Synvisc, the Sepra line of products, Carticel and Matrix-induced Autologous Chondrocyte Implantation, or MACI; and

          Genetics, which provides testing services for the oncology, prenatal and reproductive markets.markets; and

          Oncology, which develops, manufactures and distributes products for the treatment of cancer, with a focus on antibody- and small molecule-based therapies. The unit derives substantially all of its revenue from sales and royalties received on sales of Campath and Clolar and from the reimbursement of Campath development expenses.

                We report the activities of our diagnostic products, oncology, bulk pharmaceuticals and cardiovascular business units under the caption "Other." We report our corporate, general and administrative operations and corporate science activities under the caption "Corporate."

                Effective January 1, 2008, as a result of changes in how we review our business, certain general and administrative expenses, which were formerly allocated amongst our reporting segments and Other, are now allocated to Corporate.

                As a result of our acquisition of Bioenvision in October 2007, our Oncology business unit, which was formerly reported combined with "Other," now meets the criteria for disclosure as a separate reporting segment. We have revised our 2007 segment disclosures to conform to our 2008 presentation.


        GENZYME CORPORATION AND SUBSIDIARIES

        Notes to Unaudited, Consolidated Financial Statements (Continued)

        2.    Basis of Presentation and Significant Accounting Policies

        Basis of Presentation

                Our unaudited, consolidated financial statements for each period include the statements of operations and comprehensive income, balance sheets and statements of cash flows for our operations taken as a whole. We have eliminated all intercompany items and transactions in consolidation. We have reclassified certain 2006 data to conform to our 2007 presentation. We prepare our unaudited, consolidated financial statements following the requirements of the SEC for interim reporting. As permitted under these rules, we condense or omit certain footnotes and other financial information that are normally required by accounting principles generally accepted in the United States.

                These financial statements include all normal and recurring adjustments that we consider necessary for the fair presentation of our financial position and results of operations. Since these are interim financial statements, you should also read our audited, consolidated financial statements and notes included in our 20062007 Form 10-K. Revenues, expenses, assets and liabilities can vary from quarter to quarter. Therefore, the results and trends in these interim financial statements may not be indicative of results for future periods.



                Our unaudited, consolidated financial statements for each period include the accounts of our wholly-ownedwholly owned and majority-ownedmajority owned subsidiaries. As a result of our adoption of FASB Interpretation No., or FIN, 46R, "Consolidation"Consolidation of Variable Interest Entities," we also consolidate certain variable interest entities for which we are the primary beneficiary. For consolidated subsidiaries in which we have less than a 100% interest, we record minority interest in our consolidated statements of operations for the ownership interest of the minority owner. We use the equity method of accounting to account for our investments in entities in which we have a substantial ownership interest (20% to 50%) which do not fall in the scope of FIN 46R, or over which we exercise significant influence. Our consolidated net income includes our share of the earnings or losses of these entities.

        Income Taxes

                Effective January 1, 2007, we adopted the provisions of FIN 48, "Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109," which clarifies the accounting for income tax positions by prescribing a minimum recognition threshold that a tax position is required to meet before being recognized in the financial statements. FIN 48 also provides guidance on the derecognition of previously recognized deferred tax items, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. Under FIN 48, we recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the tax position. The tax benefits recognized in our financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. For more information regarding the impact the adoption of FIN 48 had on our results of operations, financial condition and liquidity, see Note 13., "(Provision for) Benefit from Income Taxes," included in this report.

In September 2006, the FASB issued FAS 157, "Fair Value Measurements," which provides enhanced guidance for using fair value to measure assets and liabilities. FAS 157 establishes a common definition of fair value, provides a framework for measuring fair value under accounting principles generally accepted in the United States and expands disclosure requirements regarding fair value measurements. FAS 157 will be effective for us as of January 1, 2008. We are currently evaluating the impact, if any, the adoption of FAS 157 will have on our financial position and results of operations.

        FAS 159, "The Fair Value Option for Financial Assets and Financial Liabilities—Liabilities, Including an Amendment of FASB Statement No. 115."    In February 2007, the FASB issuedEffective January 1, 2008, we adopted FAS 159, "The Fair Value Option for Financial Assets and Financial Liabilities—Liabilities, Including an Amendment of FASB Statement No. 115," which permits, but does not require, entities to measure certain financial instruments and other assets and liabilities at fair value on an instrument-by-instrument basis. Unrealized gains and losses on items for which the fair value option has been elected should be recognized in earnings at each subsequent reporting date. In adopting FAS 159, we did not elect to measure any new assets or liabilities at their respective fair values and, therefore, the adoption of FAS 159 did not have an impact on our results of operations and financial position.

                EITF Issue No. 07-1, "Accounting for Collaborative Arrangements."    In December 2007, the Emerging Issues Task Force, or EITF, of the FASB reached a consensus on Issue No. 07-1, "Accounting for Collaborative Arrangements." The EITF concluded on the definition of a collaborative arrangement and that revenues and costs incurred with third parties in connection with collaborative arrangements would be presented gross or net based on the criteria in EITF 99-19 and other accounting literature. Companies are also required to disclose the nature and purpose of collaborative arrangements along with the accounting policies and the classification and amounts of significant financial-statement amounts related to the arrangements. EITF 07-1 will bebecome effective for us January 1, 2009 and will be applied retrospectively to all periods presented for all collaborative arrangements existing as of January 1, 2008the

        EITF Issue No. 07-3, "Accounting "Accounting for Nonrefundable Advance Payments for Goods or Services Received for Use in Future Research and Development Activities.""    In June 2007, the FASB ratified the EITF consensus reached in EITF Issue No. 07-3, "Accounting for Nonrefundable Advance Payments for Goods or Services Received for Use in Future Research and Development Activities," which provides guidance for nonrefundable prepayments for goods or services that will be used or rendered for future research and development activities and directs that such payments should be deferred and capitalized. Such amounts should be recognized as an expense as the goods are delivered or the related services are performed, or until it is no longer expected that the goods will be delivered or the services rendered. EITF 07-3 iswas effective for us beginning January 1, 2008 and will bewe applied it prospectively to new contracts we enterentered into on or after that date. Earlier application isThe implementation of this standard did not permitted. We are currently evaluating thehave a material impact if any, the adoption of EITF No. 07-3 will have on our financial position, results of operations or cash flows.

        3. Stockholders' Equity        FAS 141 (revised 2007), "Business Combinations."    In December 2007, the FASB issued FAS 141 (revised 2007), "Business Combinations," or FAS 141R, which replaces FAS 141, "Business Combinations." FAS 141R retains the underlying concepts of FAS 141 in that all business combinations are still required to be accounted for at fair value under the acquisition method of accounting but changes a number of significant aspects of applying this method. Acquisition costs will generally be expensed as incurred; noncontrolling interests will be valued at fair value at the acquisition date; IPR&D will be recorded at fair value as an indefinite-lived intangible asset at the acquisition date; restructuring costs associated with a business combination will generally be expensed subsequent to the acquisition date; and changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date generally will affect income tax expense. FAS 141R is effective for us on a prospective basis for all business combinations for which the acquisition date is on or after January 1, 2009. Early adoption is not permitted. We are currently evaluating the effects, if any, that FAS 141R will have on our consolidated financial statements.

                FAS No. 160, "Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51."    In December 2007, the FASB issued FAS 160, "Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51," which establishes new accounting and reporting standards that require the ownership interests in subsidiaries not held by the parent to be clearly identified, labeled and presented in the consolidated statement of financial position within equity, but separate from the parent's equity. FAS 160 also requires the amount of consolidated net income attributable to the parent and to the non-controlling interest, commonly referred to as the minority interest, to be clearly identified and presented on the face of the consolidated statement of income. Changes in a parent's ownership interest while the parent retains its controlling financial interest must be accounted for consistently, and when a subsidiary is deconsolidated, any retained non-controlling equity investment in the former subsidiary must be initially measured at fair value. The gain or loss on the deconsolidation of the subsidiary is measured using the fair value of any non-controlling equity investment. FAS 160 also requires entities to provide sufficient disclosures that clearly identify and distinguish between the interests of the parent and the interests of the non-controlling owners. FAS 160 is effective for us January 1, 2009 and adoption is prospective only; however, upon adoption, presentation and disclosure requirements described above must be applied retrospectively for all periods presented in our consolidated financial statements. We are currently evaluating the effects, if any, that FAS 160 will have on our consolidated financial statements.

                FAS No. 161, "Disclosures About Derivative Instruments and Hedging Activities—an amendment of FASB Statement No. 133."    In March 2008, the FASB issued FAS 161, "Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133," which amends and expands the disclosure requirements of FAS 133, "Accounting for Derivative Instruments and Hedging Activities." FAS 161 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. FAS 161 is effective prospectively for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. We are currently evaluating the effects, if any, that FAS 161 will have on our consolidated financial statements.

        3.    Fair Value Measurements

                A significant number of our financial instruments are carried at fair value. These assets and liabilities include:

          fixed income investments;

          derivatives; and

          investments in publicly-traded equity securities.

        Stock RepurchaseFair Value Measurement—Definition and Hierarchy

                Effective January 1, 2008, we implemented FAS 157, "Fair Value Measurements," for our financial assets and liabilities that are re-measured and reported at fair value at each reporting period. The adoption of FAS 157 to our financial assets and liabilities did not have a material impact on our financial position and results of operations.

                FAS 157 provides a framework for measuring fair value and requires expanded disclosures regarding fair value measurements. FAS 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability (i.e., the "exit price") in an orderly transaction between market participants at the measurement date. In May 2007,determining fair value, FAS 157 permits the use of various valuation approaches, including market, income and cost approaches. FAS 157 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the observable inputs be used when available.

                The fair value hierarchy is broken down into three levels based on the reliability of inputs. We have categorized our boardfixed income, derivatives and equity securities within the hierarchy as follows:

          Level 1—These valuations are based on a "market approach" using quoted prices in active markets for identical assets. Valuations of directors authorizedthese products do not require a stock repurchase programsignificant degree of judgment. Assets utilizing Level 1 inputs include money market funds, U.S. government securities, bank deposits and exchange-traded equity securities;

          Level 2—These valuations are based primarily on a "market approach" using quoted prices in markets that are not very active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. Fixed income assets utilizing Level 2 inputs include U.S. agency securities, including direct issuance bonds and mortgage-backed securities, asset-backed

        3.    Fair Value Measurements (Continued)

            securities, corporate bonds and commercial paper. Derivative securities utilizing Level 2 inputs include forward foreign-exchange contracts; and

          Level 3—These valuations are based on various approaches using inputs that are unobservable and significant to an aggregate maximum amountthe overall fair value measurement. Certain assets are classified within Level 3 of $1.5 billionthe fair value hierarchy because they trade infrequently and, therefore, have little or 20,000,000 sharesno transparency. We currently have no assets or liabilities that are valued with Level 3 inputs because all our fixed income and equity securities, derivatives and warrants have high or reasonable levels of price transparency.

        Valuation Techniques

                Fair value is a market-based measure considered from the perspective of a market participant who would buy the asset or assume the liability rather than our own specific measure. All of our outstanding common stock overfixed income securities are priced by our custodial agent and nationally known pricing vendors, using a variety of daily data sources, largely readily-available market data and broker quotes. To validate these prices, we compare the next three years, beginningfair market values of our fixed income investments using market data from observable and corroborated sources. We also perform the fair value calculations for our derivative and equity securities using market data from observable and corroborated sources. In periods of market inactivity, the observability of prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified from Level 1 to Level 2 or from Level 2 to Level 3.

In July 2004, the Massachusetts Business Corporation Act, or MBCA, became effective and eliminated the concept of treasury shares.

Our 2004 Equity Incentive Plan authorizes the issuance of stock options, restricted stock and restricted stock units, or RSUs. We began issuing RSUs under our 2004 Equity Incentive Plan in connection with a general grant to employees in May 2007.

On February 28, 2007, our board of directors approved our 2007 Director Equity Plan which was created to amend, restate and replace our 1998 Director Stock Option Plan. At our 2007 Annual Meeting, our shareholders also approved the 2007 Director Equity Plan. Similar to our 2004 Equity Incentive Plan, our 2007 Director Equity Plan authorizes the issuance of stock options, restricted stock and RSUs to our directors.their short-term maturities.

        5.    Mergers and Acquisitions

        Pending Acquisition of the Diagnostics Division of Diagnostic Chemicals Limited

                On November 2, 2007, we entered into an agreement with DCL, a privately-held diagnostics and biopharmaceutical company based in Charlottetown, Prince Edward Island, Canada, to acquire DCL's diagnostics division, including DCL's line of over 50 formulated clinical chemistry reagents and its diagnostics operations in Prince Edward Island, Canada and Connecticut, for an aggregate purchase price of approximately $53 million Canadian dollars, or approximately $57 million U.S. dollars (based on the November 2, 2007 spot rate for the Canadian dollar), in cash. We expect to close the transaction in December 2007.

        Acquisition of Bioenvision

                On May 29,Effective October 23, 2007, we entered into an agreementcompleted our acquisition of Bioenvision through the culmination of a two step process consisting of a tender offer completed in July 2007, and plana merger approved in October 2007. We paid gross consideration of merger with$349.9 million in cash, including $345.4 million for the outstanding shares of Bioenvision a publicly-traded biopharmaceutical company based in New York CityCommon and Edinburgh, Scotland, and Wichita Bio Corporation, one of our wholly-owned subsidiaries, to acquire Bioenvision in an all-cash transaction valued at $11.20 per outstanding share of Bioenvision Series A Preferred Stock (plus accrued but unpaid dividends) and $5.60 per outstanding shareoptions to purchase shares of Bioenvision Common Stock, orand approximately $345$5 million in aggregate.for acquisition costs.

                Bioenvision iswas focused on the acquisition, development and marketing of compounds and technologies for the treatment of cancer, autoimmune disease and infection. Effective October 23, 2007, we completed the acquisition of Bioenvision. This acquisition was completed through a two step process consisting of a tender offer completed in July 2007, and a merger approved in October 2007.

        The acquisition of Bioenvision provides us with the exclusive, worldwide rights to clofarabine. We currently market clofarabine in the United States and Canada under the brand name Clolar for relapsed and refractory pediatric acute lymphoblastic leukemia, or ALL, patients. In Europe, we co-developed clofarabine with Bioenvision and Bioenvision has been marketing the product under the brand name Evoltra, also for the treatment of relapsed and refractory pediatric ALL patients. We and Bioenvision have been developing clofarabine for diseases with significantly larger patient populations, including use as a first-line therapy for the treatment of adult acute myeloid leukemia, or AML. Clofarabine has been granted orphan drug status for ALL and AML in both the United States and European Union.

          Tender Offer

                On July 10, 2007, we completed the tender offer and purchased 2,250,000 shares of Bioenvision Series A Preferred Stock for $25.2 million, which we recorded as a component of investments in equity securities, and 8,398,098 shares of Bioenvision Common Stock for $47.0 million, which we recorded as a component of other noncurrent assets in our consolidated balance sheet. As a result of the tender offer, we acquired approximately 22% of the then outstanding shares of Bioenvision Common Stock on an as-converted basis, including 100% of the outstanding Bioenvision Series A Preferred Stock.

                We accounted for our investments in Bioenvision Series A Preferred Stock and Bioenvision Common Stock using two different methods. In the third quarter of 2007, we accounted for our investment in Bioenvision Series A Preferred Stock under the cost method of accounting because these shares did not qualify as similar or substantially similar to common stock (in-substance common stock) under the guidance of EITF Issue No. 02-14, "Whether the Equity Method of Accounting Applies When an Investor Does Not Have an Investment in Voting Stock of an Investee but Exercises



        Significant Influence through Other Means." Our initial investments in Bioenvision Common Stock and Bioenvision Series A Preferred Stock gave us significant influence over Bioenvision and, as a result, we accounted for our investment in Bioenvision Common Stock under the equity method of accounting. Accordingly, in July 2007, we recorded our initial $47.0 million investment in Bioenvision Common Stock as a single amount in other noncurrent assets in our consolidated balance sheet. Of this amount, we attributed $7.1 million to our 15% proportional share of the assets and liabilities of Bioenvision and $39.9 million, representing the excess of the purchase price over our proportional share of the net assets of Bioenvision, to the underlying intangible assets, IPR&D and goodwill based on their fair values, including $16.8 million, net of tax, to intangible assets, $19.1 million to IPR&D and $4.0 million to goodwill. Equity in income (loss) of equity method investments for the three and nine months ended September 30, 2007 reflects a total of $20.5 million of charges related to our initial investment in Bioenvision Common Stock, including a $19.1 million charge for IPR&D and a total of $1.4 million of charges for the period from July 10, 2007 through September 30, 2007, of which $1.0 million represents our portion of the losses of Bioenvision for that period and $0.4 million represents amortization expense, net of tax, related to the value assigned to technology and other intangible assets. As of September 30, 2007, other noncurrent assets in our consolidated balance sheet includes a net balance of $26.5 million for our initial investment in Bioenvision Common Stock including $47.0 million for the cash consideration we paid, which was offset by the $20.5 million of charges described above.

          Stockholder Approval of the Merger

                On October 22, 2007, a special meeting of the Bioenvision stockholders was held to seek approval for the merger. Holders of a majority of the issued and outstanding shares of Bioenvision Common Stock and Bioenvision Series A Preferred Stock, voting together as a single class on an as converted basis, approved the merger. On October 23, 2007, we paid approximately $245 million in cash consideration to the former Bioenvision stockholders and Bioenvision Common Stock ceased trading and was delisted from The Nasdaq Stock Market, Inc., or NASDAQ. In the fourth quarter of 2007, we will pay approximately $11 million of cash for the outstanding options to purchase shares of Bioenvision Common Stock. The full purchase accounting for our acquisition of Bioenvision, including the impact of our merger in October 2007, will be reflected in our consolidated financial statements as of December 31, 2007 and for the year ended December 31, 2007.

                In connection with the merger, holders of 2,880,000 shares of Bioenvision Common Stock, representing less than 5% of the outstanding shares of Bioenvision Common Stock on an as-converted basis immediately before the merger became effective, submitted written demands for appraisal of their shares and have, as a result, elected not to accept the $5.60 per share merger consideration. We refer to these stockholders as dissenting stockholders.

        Acquisition of AnorMED

                In November 2006, we acquired AnorMED, a publicly-held chemical-based biopharmaceutical company based in Langley, British Columbia, Canada, with a focus on the discovery, development and commercialization of new therapeutic products in the area of hematology, oncology and human immunodeficiency virus, or HIV. We paid gross consideration of $589.2 million in cash, including $584.2 million for the shares of AnorMED's common stock outstanding on the date of acquisition and $5.0 million for acquisition costs. Net consideration was $569.0 million as we acquired AnorMED's cash and cash equivalents totaling $20.2 million. We accounted for the acquisition as a business combination



        and accordingly, included AnorMED's results of operations in our consolidated statements of operations from November 7, 2006, the date of acquisition.

                The purchase price was allocated to the estimated fair value of the acquired tangible and intangible assets and assumed liabilities as follows (amounts in thousands, except share data):

        Purchase of 43,272,085 shares of AnorMED common stock $584,173 
        Acquisition costs  5,000

        Other intangible assets (to be amortized over 10 years)  3,500

        Deferred tax assets—noncurrent  27,380 
        Other noncurrent assets  573 
        Assumed liabilities:    
         Deferred tax liability  (25,288)
         Liabilities for exit activities  (7,733)
         Other liabilities  (21,180)
          
         
        Allocated purchase price $589,173 
          
         

                The allocation of the purchase price was adjusted in 2007 to:

          write off $2.1 million of fixed assets associated with the acquisition;

          revise the estimated liabilities related to exit activities by $1.2 million; and

          adjust the deferred taxes by $(0.7) million.

                The purchase price, as adjusted, was allocated to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price over the estimated fair value of the assets acquired and liabilities assumed amounted to $31.7$85.3 million, which was allocated to goodwill. We expect that substantially all of the amount allocated to goodwill will be deductible for tax purposes.

                The allocation of the purchase price remains subject to potential adjustments, including adjustments for liabilities associated with certain exit activities and tax restructuring activities. We recorded immaterial adjustments to the purchase price in the first quarter of 2008.

        Purchase of In-Process Research and Development

                In connection with fivecertain of our acquisitions we completed between January 1, 20042006 and September 30,December 31, 2007, we have acquired various IPR&D projects. Substantial additional research and development costs will be required prior to any of our acquired IPR&D programs and technology platforms reaching technological feasibility. In addition, once research is completed, each product candidate acquired will need to complete a series of clinical trials and receive FDA or other regulatory approvals prior to



        commercialization. Our current estimates of the time and investment required to develop these products and technologies may change depending on the different applications that we may choose to pursue. We cannot give assurances that these programs will ever reach technological feasibility or develop into products that can be marketed profitably. In addition, we cannot guarantee that we will be able to develop and commercialize products before our competitors develop and commercialize products for the same indications. If products based on our acquired IPR&D programs and technology platforms do not become commercially viable, our results of operations could be materially adversely affected. We did not complete any acquisitions in the three months ended March 31, 2008.

        Management assumes responsibility for determining the valuation of the acquired IPR&D projects. The fair value assigned to IPR&D for each acquisition is estimated by discounting, to present value, the cash flows expected once the acquired projects have reached technological feasibility. The cash flows are probability-adjusted to reflect the risks of advancement through the product approval process. In estimating the future cash flows, we also considered the tangible and intangible assets required for successful exploitation of the technology resulting from the purchased IPR&D projects and adjusted future cash flows for a charge reflecting the contribution to value of these assets.

        (2)
        IPR&D charges totaled $125.5 million related to the acquisition of Bioenvision, of which $106.4 million was charged to IPR&D and $19.1 million was charged to equity in income of equity method investments.

        Year of expected launch is not provided for AMD070 at this time because we are assessing our future plans for this program.

        (3)
        Year of expected launch is not provided for LR-103 at this time because this program is in its early stages and we are evaluating several potential applications for LR-103 to determine which application we will pursue. Therefore, the year of expected launch cannot be determined.

        (4)
        Campath is currently marketed for the treatment ofB-cell chronic lymphocytic leukemia and Clolar is marketed for the treatment of relapsed and refractory pediatric ALL. The IPR&D projects for Campath and Clolar are related to the development of these products for the treatment of other medical issues.

                In addition, we account for our investment in Bioenvision Common Stock under the equity method of accounting and, accordingly, we recorded a charge of $19.1 million in equity in income (loss) of equity method investments in our consolidated statement of operations for the three and nine months ended September 2007 for the portion of the purchase price for this investment that we allocated to IPR&D. The full purchase accounting for our acquisition of Bioenvision, including the impact of our merger in October 2007, will be reflected in our consolidated financial statements as of December 31, 2007 and for the year ended December 31, 2007.


        Exit Activities

                In connection with several of our acquisitions, we initiated integration plans to consolidate and restructure certain functions and operations, including the relocation and termination of certain personnel of these acquired entities and the closure of certain of the acquired entities' leased facilities. These costs have been recognized as liabilities assumed in connection with the acquisition of these entities in accordance with EITF Issue No. 95-3, "Recognition of Liabilities in Connection with a Purchase or Business Combination," and are subject to potential

                    We and BioMarin Pharmaceutical Inc., or BioMarin, formed BioMarin/Genzyme LLC to develop and commercialize Aldurazyme, a recombinant form of the human enzyme alpha-L-iduronidase, used to treat an LSD known as mucopolysaccharidosis I, or MPS I. We recordPrior to January 1, 2008, we recorded our portion of the incomeresults of BioMarin/Genzyme LLC in equity in income (loss) of equity method investments in our unaudited, consolidated statements of operations.

                      Effective January 1, 2008, we restructured our relationship with BioMarin/Genzyme LLC regarding the manufacturing and commercialization of Aldurazyme by entering into several new agreements. BioMarin/Genzyme LLC will no longer engage in commercial activities related to $5.0 million forAldurazyme and will solely:

                hold the same period of 2006;intellectual property relating to Aldurazyme and other future collaboration products; and

                $20.8engage in research and development activities that are mutually selected and funded by BioMarin and us, the costs of which we will share equally.

              Under the restructured relationship, BioMarin/Genzyme LLC has licensed all intellectual property related to Aldurazyme and other collaboration products on a royalty-free basis to BioMarin and us. BioMarin holds the manufacturing rights and we hold the global marketing rights. We are required to pay BioMarin a tiered royalty payment ranging from 39.5% to 50% of worldwide net product sales of Aldurazyme.

                      As a result of the restructuring of our relationship with BioMarin/Genzyme LLC, effective January 1, 2008, in accordance with the provisions of FIN 46R, we began consolidating the results of BioMarin/Genzyme LLC. Upon consolidation of BioMarin/Genzyme LLC, we recorded the assets and liabilities of the joint venture in our consolidated balance sheets at fair value. The value of the intellectual property of the joint venture of approximately $480.5 million was recorded as an intangible asset and will be amortized over a useful life of 20 years. As this intellectual property has been out-licensed from the joint venture to BioMarin and us for no consideration, a noncurrent liability was recorded for an amount equal to the negative value of these licenses. The noncurrent liability is being amortized over a period of 20 years. We recorded BioMarin's portion of the joint venture's losses, the

            Stock Repurchase

                    During the three months ended March 31, 2008, we repurchased and retired an additional 1,000,000 shares of our common stock at an average price of $73.20 per share for a total of $73.2 million in cash, including fees. Since June 2007, when we first began making repurchases, we have repurchased a cumulative total of 4,500,000 shares of our common stock at an average price of $67.71 per share for a total of $304.8 million in cash, including fees. As a result, we recorded the repurchases in our consolidated balance sheets as of March 31, 2008 and December 31, 2007, as a reduction to our common stock account for the par value of the repurchased shares and as a reduction to our additional paid-in capital account.

            We also capitalized stock-based compensation expense to inventory of $3.1 million for the three months ended March 31, 2008 and $2.9 million for the three months ended March 31, 2007, all of which is attributable to participating employees that support our manufacturing operations. We amortize stock-based compensation expense capitalized to inventory based on inventory turns.

                    At March 31, 2008, there was $219.7 million of pre-tax stock-based compensation expense, net of estimated forfeitures, related to unvested awards not yet recognized which is expected to be recognized over a weighted average period of 1.9 years.

            Notes Receivable from Stockholders

                    In connection with our acquisition of Biomatrix, we assumed notes receivable from five former employees, directors and consultants of Biomatrix, which we refer to as the Makers of the notes. The notes are full-recourse promissory notes that accrue interest at rates ranging from 5.30% to 7.18% and mature at various dates from May 2007 through September 2009, at which point the outstanding principal and accrued interest for each note will become payable. As of March 31, 2008, there is a total of $15.8 million outstanding for these notes, including $10.2 million of principal and $5.6 million of accrued interest. Of these amounts, a total of $8.0 million of principal and $4.6 million of accrued interest is attributable to one Maker. We record the amount of principal and interest outstanding under the notes in stockholders' equity because the notes were originally received in exchange for the issuance of Biomatrix common stock, which was subsequently converted into Genzyme Stock.

                    On April 29, 2008, we received $1.0 million of cash from one of the Makers as payment in full upon maturity of that Maker's note, including accrued interest. A total of $2.8 million in principal and accrued interest has come due under the notes but has not yet been repaid, of which $1.9 million was

            due as of March 31, 2008 and an additional $0.8 million became due as of April 30, 2008. We are pursuing collection of these past due amounts and the notes will continue to accrue interest until the outstanding principal and accrued interest have been repaid. A total of $0.7 million of the principal and accrued interest that was due but not repaid as of April 30, 2008 is attributable to the Maker that owes a total of $8.0 million in principal under the notes. In June 2008, an additional $6.7 million in principal will become due from this Maker plus accrued interest.

            12. Other    Commitments and Contingencies

              Legal Proceedings

                    We periodically become subject to legal proceedings and claims arising in connection with our business.


                    Through June 30, 2003, we had three outstanding series of common stock, which we referred to as tracking stocks; Genzyme General Stock (which we now refer to as Genzyme Stock), Biosurgery Stock and Molecular Oncology Stock. Four lawsuits were filed against us regarding the exchange of all of the outstanding shares of Biosurgery Stock for shares of Genzyme Stock in connection with the elimination of our tracking stocks in July 2003. Each of the lawsuits was a purported class action on behalf of holders of Biosurgery Stock. The first case, filed in the Massachusetts Superior Court (MSC) in May 2003, alleged a breach of the implied covenant of good faith and fair dealing in our charter and a breach of our board of directors' fiduciary duties. The plaintiff in this case sought an injunction to adjust the exchange ratio for the tracking stock exchange. The MSC dismissed the complaint in its entirety in November 2003. Upon appeal, the Massachusetts Appeals Court upheld the dismissal by the MSC of the fiduciary duty claim, but reversed the earlier decision to dismiss the implied covenant claim. The Massachusetts Supreme Judicial Court (SJC) granted our petition for further appellate review. On June 4, 2007, the SJC reversed the Appeals Court's decision and affirmed dismissal of the complaint in its entirety. On July 25, 2007, the SJC denied the plaintiff's petition for rehearing. Two substantially similar cases were filed in the MSC in August and October 2003. These cases were consolidated in January 2004, and in July 2004, the consolidated case was stayed pending disposition of a fourth case, which was filed in the U.S. District Court for the Southern District of New York in June 2003. As amended, this complaint alleged violations of federal securities laws, as well as various state law claims, related to the exchange, on behalf of a certified class of holders of Biosurgery Stock as of May 8, 2003. On August 6, 2007, we reached an agreement-in-principle with counselagreement in principle to settle lawsuits related to our 2003 repurchase of Biosurgery Stock for $64.0 million. The court entered an order approving the settlement on December 30, 2007. As a result, we recorded a liability for the plaintiff class to settle and dismiss this case for approximately $64 million. A definitive settlement agreement was approved by the court on October 26, 2007. Because the memberspayment of the class in the New York action released all claims, the settlement has,$64.0 million as a practical matter, resolved thecharge to selling, general and administrative expenses, or SG&A, in our consolidated casestatements of operations in the MSC.June 2007, which we subsequently paid in August 2007. We have submitted claims to our insurers for reimbursement of portions of the expenses incurred and to be incurred in connection with these cases; the insurer has purported to deny coverage.coverage and therefore, we have not recorded a receivable for any potential recovery from our insurer. We intend to vigorously pursue our rights with respect to insurance coverage. As a result,coverage and to the extent we recorded a liability forare successful, we will record the settlement payment of approximately $64 million as a charge to selling, general and administrative expense, or SG&A,recovery in our consolidated statementstatements of operations in June 2007, which we subsequently paid in August 2007.operations.

Although we cannot predict the outcome of other legalthese additional proceedings to which we may become subject in the normal course of business or estimate the amount or range of any reasonably possible loss we might incur ifand claims, we do not prevail inbelieve the final, non-appealable determinationsultimate resolution of such matters. Therefore, we have no current accruals forany of these potential contingencies.

                non-deductible stock-based compensation expenses; and

                non-deductible expenses associated with the settlement of litigation related to the consolidation of our former tracking stocks.

              Our effective tax ratetotaling $8.1 million for the three and nine months ended September 30, 2006, was also impacted by a charge for impaired goodwill of $219.2March 31, 2008 and $6.9 million of which $29.5 million was not deductible for tax purposes.

                      Effective January 1, 2007, we adopted FIN 48 and recognized a cumulative effect adjustment of $33.9 million to increase our retained earnings balance as of January 1, 2007, which consisted of $25.8 million to record the combined effect of our gain contingency and the change in the recognition standard pursuant to the settlement criteria of FASB Staff Position, or FSP, FIN 48-1, "Definition ofSettlement in FASB Interpretation No. 48," or FSP FIN 48-1, and $8.1 million resulting from our settlement of the IRS audit for tax years 2002 to 2003. After these adjustments, as of January 1, 2007, we had approximately $36.5 million of total gross unrealized tax benefits, of which approximately $26.6 million represents the amount of unrecognized tax benefits that, if recognized, would favorably affect our effective income tax rate in future periods. These gross unrealized tax benefits did not change significantly during the nine months ended September 30, 2007.

                      We continue to recognize interest relating to unrecognized tax benefits within our provision for income taxes but have not recorded any amounts related to potential penalties. The amount of accrued interest related to unrecognized tax benefits within our provision for income taxes for the three and nine months ended September 30, 2007, and our accrued interest related to unrecognized tax benefits as of January 1, 2007 and September 30, 2007 were not significant.

              March 31, 2007.

                      We are subject to U.S. federal income tax and various state, local and international income taxes in numerous jurisdictions, however, our only significant tax jurisdiction is the United States. We record liabilities for income tax contingencies based on our best estimate of the underlying exposures.        We are currently under IRS audit for tax years 2004 to 2005 and in certain state and foreign jurisdictions from 2003 forward.various states for 1999 to 2005. We believe that we have provided sufficiently for all audit exposuresexposures. We expect to settle the 2004 to 2005 IRS audit within the next twelve months and assessments.do not expect that the settlement will have a material impact on our financial position or results of operations. Settlement of these audits or the expiration of the statute of limitations on the assessment of income taxes for any tax year may result in an increase ora reduction of future tax provisions. Any such tax or tax benefit would be recorded upon final resolutionthe effective settlement of the auditsaudit or expiration of the applicable statute of limitations.

              ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF GENZYME CORPORATION AND SUBSIDIARIES' FINANCIAL CONDITION AND RESULTS OF OPERATIONS

                      When reviewing the discussion below, you should keep in mind the substantial risks and uncertainties that characterize our business. In particular, we encourage you to review the risks and uncertainties described under the captionheading "Risk Factors" below. These risks and uncertainties could cause actual results to differ materially from those forecasted in forward-looking statements or implied by past results and trends. Forward-looking statements are statements that attempt to project or anticipate future developments in our business; we encourage you to review the examples of forward-looking statements included under the heading "Note Regarding Forward-Looking Statements" at the beginning of this report. These statements, like all statements in this report, speak only as of the date of this report (unless another date is indicated), and we undertake no obligation to update or revise the statements in light of future developments.

              INTRODUCTION

                      We are a global biotechnology company dedicated to making a major impact on the lives of people with serious diseases. Our broad product and service portfolio is focused on rare disorders, renal diseases, orthopaedics, organ transplant, and diagnostic and predictive testing.testing, and cancer. We are organized into fivesix financial reporting units, which we also consider to be our reporting segments:

                Renal, which develops, manufactures and distributes products that treat patients suffering from renal diseases, including chronic renal failure. The unit derives substantially all of its revenue from sales of RenagelRenagel/Renvela (including sales of bulk sevelamer) and Hectorol;

                Therapeutics, which develops, manufactures and distributes therapeutic products, with an expanding focus on products to treat patients suffering from genetic diseases and other chronic debilitating diseases, including a family of diseases known as LSDs, and other specialty therapeutics, such as Thyrogen. The unit derives substantially all of its revenue from sales of Cerezyme, Fabrazyme, Myozyme, Aldurazyme and Thyrogen;

                Transplant, which develops, manufactures and distributes therapeutic products that address pre-transplantation, prevention and treatment of graft rejection in organ transplantation and other hematologic and auto-immune disorders. The unit derives substantially all of its revenue from sales of Thymoglobulin;

                Biosurgery, which develops, manufactures and distributes biotherapeutics and biomaterial-based products, with an emphasis on products that meet medical needs in the orthopaedics and broader surgical areas. The unit derives substantially all of its revenue from sales of Synvisc, the Sepra line of products, Carticel and MACI; and

                Genetics, which provides testing services for the oncology, prenatal and reproductive markets.markets; and

                Oncology, which develops, manufactures and distributes products for the treatment of cancer, with a focus on antibody- and small molecule-based therapies. The unit derives substantially all of its revenue from sales and royalties received on sales of Campath and Clolar and from the reimbursement of Campath development expenses.

                      We report the activities of our diagnostic products, oncology, bulk pharmaceuticals and cardiovascular business units under the caption "Other." We report our corporate, general and administrative operations and corporate science activities under the caption "Corporate."

                      Effective January 1, 2008, as a result of a change in how we review our business, certain general and administrative expenses which were formerly allocated amongst our reporting segments and Other, are now allocated to Corporate.


                      As a result of our acquisition of Bioenvision in October 2007, our Oncology business unit, which was formerly reported combined with "Other," now meets the criteria for disclosure as a separate reporting segment. We have revised our 2007 segment disclosures to conform to our 2008 presentation.

              MERGERS AND ACQUISITIONS

                      The following acquisitions were accounted for as business combinations and, accordingly, we have included their results of operations in our consolidated statements of operations from the date of acquisition.

              Pending Acquisition of the Diagnostics DivisionDiagnostic Assets of Diagnostic Chemicals Limited

                      On November 2,December 3, 2007, we entered into an agreement withacquired certain diagnostic assets from Diagnostic Chemicals Limited, or DCL, a privately-held diagnostics and biopharmaceutical company based in Charlottetown, Prince Edward Island, Canada, to acquire DCL's diagnostics division, including DCL's line of over 50 formulated clinical chemistry reagents and its diagnostics operations in Prince Edward Island, Canada and Connecticut, for an aggregate purchase priceConnecticut. We paid consideration of approximately $53$53.8 million Canadian dollars, or approximately $57 million U.S. dollars (based



              on the November 2, 2007 spot rate for the Canadian dollar), in cash. We expect to close the transaction in December 2007.

              Acquisition of Bioenvision

                      On May 29,Effective October 23, 2007, we entered into an agreementcompleted our acquisition of Bioenvision through the culmination of a two step process consisting of a tender offer completed in July 2007, and plana merger approved in October 2007. We paid gross consideration of merger with$349.9 million in cash, including $345.4 million for the outstanding shares of Bioenvision a publicly-traded biopharmaceutical company based in New York CityCommon and Edinburgh, Scotland, and Wichita Bio Corporation, one of our wholly-owned subsidiaries, to acquire Bioenvision in an all-cash transaction valued at $11.20 per outstanding share of Bioenvision Series A Preferred Stock (plus accrued but unpaid dividends) and $5.60 per outstanding shareoptions to purchase shares of Bioenvision Common Stock, orand approximately $345$5 million in aggregate.for acquisition costs. Net consideration was $304.7 million as we acquired Bioenvision's cash and cash equivalents totaling $45.2 million.

                      Bioenvision iswas focused on the acquisition, development and marketing of compounds and technologies for the treatment of cancer, autoimmune disease and infection. Effective October 23, 2007, we completed the acquisition of Bioenvision. This acquisition was completed through a two step process consisting of a tender offer completed in July 2007, and a merger approved in October 2007.

              The acquisition of Bioenvision provides us with the exclusive, worldwide rights to clofarabine. We currently market clofarabine in the United States and Canada under the brand name Clolar for relapsed and refractory pediatric ALL patients. In Europe, we co-developed clofarabine with Bioenvision and Bioenvision hashad been marketing the product under the brand name Evoltra, also for the treatment of relapsed and refractory pediatric ALL patients. We and Bioenvision have beenare developing clofarabine for diseases with significantly larger patient populations, including use as a first-line therapy for the treatment of adult acute myeloid leukemia, or AML. Clofarabine has been granted orphan drug status for the treatment of ALL and AML in both the United States and European Union.

                Tender OfferSTRATEGIC TRANSACTION

                      On July 10, 2007, we completed the tender offer and purchased 2,250,000 shares of Bioenvision Series A Preferred Stock for $25.2 million, which we recorded as a component of investments in equity securities, and 8,398,098 shares of Bioenvision Common Stock for $47.0 million, which we recorded as a component of other noncurrent assets in our consolidated balance sheet. As a result of the tender offer, we acquired approximately 22% of the then outstanding shares of Bioenvision Common Stock on an as-converted basis, including 100% of the outstanding Bioenvision Series A Preferred Stock.

                      We accounted for our investments in Bioenvision Series A Preferred Stock and Bioenvision Common Stock using two different methods. In the third quarter of 2007, we accounted for our investment in Bioenvision Series A Preferred Stock under the cost method of accounting because these shares did not qualify as similar or substantially similar to common stock (in-substance common stock) under the guidance of EITF Issue No. 02-14, "Whether the Equity Method of Accounting Applies When an Investor Does Not Have an Investment in Voting Stock of an Investee but Exercises Significant Influence through Other Means." Our initial investments in Bioenvision Common Stock and Bioenvision Series A Preferred Stock gave us significant influence over Bioenvision and, as a result, we accounted for our investment in Bioenvision Common Stock under the equity method of accounting. Accordingly, in July 2007, we recorded our initial $47.0 million investment in Bioenvision Common Stock as a single amount in other noncurrent assets in our consolidated balance sheet. Of this amount, we attributed $7.1 million to our 15% proportional share of the assets and liabilities of Bioenvision and $39.9 million, representing the excess of the purchase price over our proportional share of the net assets of Bioenvision, to the underlying intangible assets, IPR&D and goodwill based on their fair values, including $16.8 million, net of tax, to intangible assets, $19.1 million to IPR&D and $4.0 million to goodwill. Equity in income (loss) of equity method investments for the three and nine months ended September 30, 2007, reflects a total of $20.5 million of charges related to our initial investment in Bioenvision Common Stock, including a $19.1 million charge for IPR&D and a total of $1.4 million of charges for the period from July 10, 2007 through September 30, 2007, of which $1.0 million represents



              our portion of the losses of Bioenvision for that period and $0.4 million represents amortization expense, net of tax, related to the value assigned to technology and other intangible assets. As of September 30, 2007, other noncurrent assets in our consolidated balance sheet includes a net balance of $26.5 million for our initial investment in Bioenvision Common Stock, consisting of the $47.0 million cash consideration we paid, which was offset by the $20.5 million of charges described above.

                Stockholder Approval of the Merger

                      On October 22, 2007, a special meeting of the Bioenvision stockholders was held to seek approval for the merger. Holders of a majority of the issued and outstanding shares of Bioenvision Common Stock and Bioenvision Series A Preferred Stock, voting together as a single class on an as converted basis, approved the merger. On October 23, 2007, we paid approximately $245 million in cash consideration to the former Bioenvision stockholders and Bioenvision Common Stock ceased trading and was delisted from NASDAQ. In the fourth quarter of 2007, we will pay approximately $11 million of cash for the outstanding options to purchase shares of Bioenvision Common Stock. The full purchase accounting for our acquisition of Bioenvision, including the impact of our merger in October 2007, will be reflected in our consolidated financial statements as of December 31, 2007 and for the year ended December 31, 2007.

                      In connection with the merger, holders of 2,880,000 shares of Bioenvision Common Stock, representing less than 5% of the outstanding shares of Bioenvision Common Stock on an as-converted basis immediately before the merger became effective, submitted written demands for appraisal of their shares and have, as a result, elected not to accept the $5.60 per share merger consideration. We refer to these stockholders as dissenting stockholders.

              Acquisition of AnorMEDStrategic Alliance with Isis

                      On January 7, 2008, we entered into a strategic alliance with Isis, whereby we obtained an exclusive license to develop and commercialize mipomersen, a lipid-lowering drug targeting apolipoprotein B-100, for the treatment of FH, an inherited disorder that causes exceptionally high levels of LDL-cholesterol. In November 2006,February 2008, we acquired AnorMED, a publicly-traded chemical-based biopharmaceutical company based in Langley, British Columbia, Canada, with a focus on the discovery, development and commercializationpaid Isis $150.0 million to purchase five million shares of new therapeutic products in the areaIsis common stock for $30 per share, consisting of hematology, oncology and human immunodeficiency virus, or HIV. We paid gross consideration of $589.2 million in cash, including $584.2$69.9 million for the shares of AnorMED's commonpremium we paid to purchase the stock, outstanding on the date of acquisitionwhich was charged to research and $5.0 million for acquisition costs. Net consideration was $569.0 million as we acquired AnorMED's cash and cash equivalents totaling $20.2 million. As part of the transaction, we acquired Mozobil, a late-stage product candidate in development for hematopoietic stem cell transplantation, which we have added to our Transplant business. Multiple early studies showed that Mozobil rapidly increases the number of stem cells that move out of the bone marrow and into a patient's blood, which is an important step in preparing a patient for a stem cell transplant. On July 19, 2007, we announced the successful completion of a phase 3 clinical trial of Mozobil in treating non-Hodgkin's lymphoma and on August 2, 2007, we announced the successful completion of a second phase 3 clinical trial of Mozobil in treating multiple myeloma. The trials met their respective primary and secondary endpoints. We accounted for the acquisition as a business combination and accordingly, we included AnorMED's results of operationsexpenses in our consolidated statements of operations, from November 7, 2006,and $80.1 million for the date of acquisition.

                      The purchase price, as adjusted, was allocated to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price over the estimated fair value of the assets acquired and liabilities assumed amounted to $31.7 million,stock, which was allocatedrecorded as an increase to goodwill.investment in equity securities in our consolidated balance sheet.

              CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT JUDGMENTS AND ESTIMATES

                      Our critical accounting policies and significant judgments and estimates are set forth under the heading "Management's Discussion and Analysis of Genzyme Corporation and Subsidiaries' Financial Condition and Results of Operations—Critical Accounting Policies and Significant Judgments and Estimates" in Exhibit 13 to our 20062007 Form 10-K. Additional information regarding significant judgments and estimates and updatesrelated to our policies for Revenue Recognition, Income Taxes and Inventoriessales reserves are included below. Excluding these additional disclosures, thereThere have been no significant changes to our other critical accounting policies or significant judgments and estimates since December 31, 2006.2007. Additional information regarding our provisions and estimates for our product sales allowances, sales allowance reserves and accruals, and distributor fees are included below.

              Revenue Recognition

              Product Sales

                      The timing of product shipments and receipts by the customer can have a significant impact on the amount of revenue recognized in a particular period. A significant portion of our products are sold at least in part through wholesalers and specialty distributors, along with direct sales to hospitals, homecare providers, government agencies and physicians. Consequently, our net sales and quarterly growth comparisons may be affected by fluctuations in the buying patterns of our major distributors and other trade buyers, which may result from seasonality, pricing, wholesaler buying decisions or other factors. Inventory in the distribution channel consists of inventory held by wholesalers and specialty distributors, who are our customers, and inventory held by their retail customers, such as pharmacies and hospitals. Our revenue in a particular period can be impacted by increases or decreases in channel inventories. Significant increases in wholesaler or retail inventories could result in reduced purchases in subsequent periods, or product returns from the distribution channel due to overstocking, low end-user demand or product expiration.

                      We use a variety of data sources to determine the amount of inventory in the distribution channel. For most product lines, we receive data on sales and inventory levels directly from our primary customers. For key product lines in our Renal and Therapeutics areas, our data sources also include prescription and wholesaler data purchased from external data providers. As part of our efforts to limit the amount of Renal and Therapeutics inventory held by distributors and to gain improved visibility into the distribution channel, we have executed agreements to limit the amounts of inventory they carry and to provide us ongoing reports to verify distributor inventory levels and sales data.

              Product Sales Allowances

                      Sales of many biotechnology products in the United States are subject to increased pricing pressure from managed care groups, institutions, government agencies, and other groups seeking discounts. We and other biotechnology companies in the U.S. market are also required to provide statutorily defined rebates and discounts to various U.S. government agencies in order to participate in the Medicaid program and other government-funded programs. In most international markets, we operate in an environment where governments may and have mandated cost-containment programs, placed restrictions on physician prescription levels and patient reimbursements, emphasized greater use of generic drugs and enacted across-the-board price cuts as methods to control costs. The sensitivity of our estimates can vary by program, type of customer and geographic location. Estimates associated with Medicaid and other government allowances may become subject to adjustment in a subsequent period due to the time delay between the recording of the accrual and its ultimate settlement.period.

                      We record product sales net of the following significant categories of product sales allowances:

                Contractual adjustments—We offer chargebacks and contractual discounts and rebates, which we collectively refer to as contractual adjustments, to certain private institutions and various

                  government agencies in both the United States and international markets. We record chargebacks and contractual discounts as allowances against accounts receivable in our consolidated balance sheets. We account for rebates by establishing an accrual for the amounts payable by us to these agencies and institutions, which is included in accrued liabilities in our consolidated balance sheets. We estimate the allowances and accruals for our contractual adjustments based on historical experience and current contract prices, using both internal data as well as information obtained from external sources, such as independent market research agencies and data from wholesalers. We continually monitor the adequacy of these estimates and adjust the allowances and accruals periodically throughout each quarter to reflect our actual experience. In evaluating these allowances and accruals, we consider several factors, including significant changes in the sales performance of our products subject to contractual adjustments, inventory in the distribution channel, changes in U.S. and foreign healthcare legislation impacting rebate or allowance rates, changes in contractual discount rates and the estimated lag time between a sale and payment of the corresponding rebate;



                Discounts—In some countries, we offer cash discounts for certain products as an incentive for prompt payment, which are generally a stated percentage off the sales price. We account for cash discounts by reducing accounts receivable by the full amounts of the discounts. We consider payment performance and adjust the accrual to reflect actual experience; and

                Sales returns—We record allowances for product returns at the time product sales are recorded. The product returns reserve is estimated based on the returns policies for our individual products and our experience of returns for each of our products. If the price of a product changes or if the history of product returns changes, the reserve is adjusted accordingly. We

                  determine our estimates of the sales return accrual for new products primarily based on the historical sales returns experience of similar products, such as those within the same line of product or those within the same or similar therapeutic category.

              Distributor Fees

                      EITF Issue No. 01-09,01-9, "Accounting for Consideration given by a Vendor to a Customer (including a Reseller of a Vendor's Products)" specifies that cash consideration (including a sales incentive) given by a vendor to a customer is presumed to be a reduction of the selling prices of the vendor's products or services and, therefore, should be characterized as a reduction of revenue. We include such fees in contractual adjustments, which are recorded as a reduction to product sales. That presumption is overcome and the consideration should be characterized as a cost incurred if, and to the extent that, both of the following conditions are met:

                the vendor receives, or will receive, an identifiable benefit (goods or services) in exchange for the consideration; and

                the vendor can reasonably estimate the fair value of the benefit received.

                      We record service fees paid to our distributors for services as a charge to SG&A, a component of operating expenses, only if the criteria set forth above are met. The following table sets forth the

              Income Taxes

                      Effective January 1, 2007, we adopted the provisions of FIN 48, which clarifies the accounting for income tax positions by prescribing a minimum recognition threshold that a tax position is required to meet before being recognized&A (amounts in the financial statements. FIN 48 also provides guidance on the derecognition of previously recognized deferred tax items, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. Under FIN 48, we recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the tax position. The tax benefits recognized in our financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution.

                      We operate in numerous countries where our income tax returns are subject to audit and adjustment by local tax authorities. Because we operate globally, the nature of the uncertain tax positions is often very complex and subject to change and the amounts at issue can be substantial. We develop our cumulative probability assessment of the measurement of uncertain tax positions using internal expertise, experience, judgment and assistance from professional advisors. Estimates are refined as additional information becomes known. Any outcome upon settlement that differs from our current estimate may result in additional or lower tax expense in future periods.

                      As of January 1, 2007, we had approximately $36.5 million of total gross unrealized tax benefits, of which approximately $26.6 million represents the amount of unrecognized tax benefits that, if recognized, would favorably affect our effective income tax rate in future periods. These gross unrealized tax benefits did not change significantly during the nine months ended September 30, 2007.

                      We continue to recognize interest related to unrecognized tax benefits within our provision for income taxes but have not recorded any amounts related to potential penalties. The amount of accrued interest related to unrecognized tax benefits included in our provision for income taxes for the three and nine months ended September 30, 2007, and our accrued interest related to unrecognized tax benefits as of January 1, 2007 and September 30, 2007, were not significant.thousands):

              Inventories

                      We value inventories at cost or, if lower, fair value. We determine cost using the first-in, first-out method. We analyze our inventory levels quarterly and write down inventory that has become obsolete, inventory that has a cost basis in excess of its expected net realizable value and inventory in excess of expected requirements. Expired inventory is disposed of and the related costs are written off. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required.

                      We capitalize inventory produced for commercial sale, which may result in the capitalization of inventory prior to regulatory approval. In no event is inventory capitalized prior to the completion of a phase 3 clinical trial. If a product is not approved for sale, it would result in the write off of the inventory and a charge to earnings. Our total inventories at September 30, 2007 included $17.4 million of inventory for Renvela that had not yet been approved for sale. On October 22, 2007, the FDA granted marketing approval for Renvela.

                      As of June 30, 2007, we had placed four lots of Thymoglobulin finished goods inventory, valued at $11.8 million, under review pending investigation and resolution of out of trend assay results we observed during quality testing. In September 2007, we determined that these lots did not meet our specifications for saleable product and recorded a charge of $11.8 million to cost of products sold to write off the inventory for these lots. Currently, we have three additional finished lots of Thymoglobulin, valued at approximately $8 million, which are under review to determine whether they meet product specifications. If we determine that any of those lots do not meet the specifications for saleable product, we will write off that inventory as a charge to earnings. Even with the four finished lots of Thymoglobulin that have been written off and the possibility of lots under review being written off, we currently expect to be able to meet projected market demand. We will continue to closely monitor our inventory levels and intend to manage production in order to maintain adequate supply levels in 2008.

Sales of Hectorol increased 19% to $30.3Renvela in the United States were $4.6 million for the three months ended March 31, 2008. We are currently pursuing regulatory approvals in Europe, South America and in other markets internationally.

                      In October 2007, an FDA advisory committee voted to recommend that the agency extend the indications for phosphate binders to include pre-dialysis patients with hyperphosphatemia. We are engaged in discussions with the FDA regarding the expansion of the product's labeling to include CKD patients with hyperphosphatemia who have not progressed to dialysis. In addition, we expect to file for approval of a powder form of Renvela that may make it easier for patients to comply with their prescribed treatment program. While Renagel will remain available for a period of time, our long-term goal is to transition patients to Renvela.

                      Sales of Hectorol increased 29%3% to $85.9 million for the nine months ended September 30, 2007, as compared to $25.5$29.1 million for the three months ended and $66.8March 31, 2008 as compared to $28.3 million for the nine months ended September 30, 2006,same period of 2007, primarily due to price increases for the 0.5 and 2.5 microgram tablets in July and December 2006 and a price increase for Hectorol IV in April 2006, as well as higher end-user demand during both periods.demand.

                      We expect sales of RenagelRenagel/Renvela and Hectorol to continue to increase, driven primarily by growing patient access to these products, including through the Medicare Part D program in the United States, and the continued adoption of the products by nephrologists worldwide. We expect adoptionAdoption rates for RenagelRenagel/Renvela are expected to trend favorably as a result of our DCOR trialthe recent introduction of Renvela in the U.S. market, anticipation of a label expansion to include hyperphosphatemic patients who are not on dialysis, and the growing acceptanceintroduction of a powder formulation expected in the first half of 2009. Adoption rates for Hectorol are expected to trend favorably as a result of growth of the National Kidney Foundation's 2003 Kidney Disease Outcome Quality Initiative, or K/DOQI, Guidelines for Bone Metabolism and Disease in CKD market and the RIND study. Renagelanticipated launch of a 1 mg capsule form of Hectorol in the first half of 2009. In addition, we expect adoption rates to increase for both Renagel/Renvela and Hectorol as the result of our recent expansion and redeployment of our Renal sales force.

                      Renagel/Renvela and Hectorol compete with several other products and our future sales may be impacted negatively by these products. We discuss someIn addition, a generic manufacturer has filed an Abbreviated New Drug Application (ANDA) seeking to market a generic version of these competitors underHectorol prior to the heading "Risk Factors—Our future success will depend on our ability to effectively develop and market our products and services against thoseexpiration dates of our competitors," included inpatents covering the product. If this report.or any other generic manufacturer were to receive approval to sell a generic version of Hectorol, our revenues from this product would be adversely affected. In addition, our ability to continue to increase sales of RenagelRenagel/Renvela and Hectorol will depend on many other factors, including our ability to optimize dosing and improve patient compliance with RenagelRenagel/Renvela dosing, the availability of reimbursement from third-party payors and the extent of coverage, including under the Medicare Part D program. Also, the accuracy of our estimates of fluctuations in the payor mix and our ability to effectively manage wholesaler inventories and the levels of compliance with the inventory management programs we implemented for Renagel and Hectorol with our wholesalers could impact the revenue from our Renal reporting segment that we record from period to period.

                      On October 22, 2007, the FDA granted marketing approval for Renvela, a second-generation buffered form of Renagel for the control of serum phosphorus in patients with CKD on dialysis. We expect to launch Renvela for dialysis patients in the United States during the first quarter of 2008 and are pursuing regulatory approvals in Europe, South America and in other markets internationally. We will continue to make Renagel available, with the long-term goal of transitioning patients to Renvela.



                      We expect Renvela will enable us to expand the market for our phosphate binder by reaching patients with CKD who have not progressed to dialysis. In October 2007, an FDA advisory committee voted to recommend that the agency extend the indications for phosphate binders to include pre-dialysis patients with hyperphosphatemia. During the first half of 2008, we plan to file a supplemental New Drug Application with the FDA seeking approval of Renvela for hyperphosphatemic patients with CKD who are not on dialysis. In addition, we expect to file for approval of a powder form of Renvela that may make it easier for patients to comply with their prescribed treatment program.

              Therapeutics

                      Therapeutics product revenue increased 21%33% to $471.2$568.5 million for the three months ended and 23% to $1.4 billion for the nine months ended September 30, 2007,March 31, 2008, as compared to the same periodsperiod of 2006,2007, due to continued growth in sales of Cerezyme, Fabrazyme and ThyrogenMyozyme and the inclusion of Aldurazyme sales in our results beginning in 2008. As a result of our restructured relationship with BioMarin and BioMarin/Genzyme LLC regarding the manufacturing, marketing and sale of Aldurazyme, effective January 1, 2008, we began to the launchrecord all sales of Myozyme in the European Union, the United States and Canada in 2006.Aldurazyme.

                      The 13%15% growth in sales of Cerezyme to $286.1$304.3 million for the three months ended and 12% growth in sales to $832.8 million for the nine months ended September 30, 2007,March 31, 2008, as compared to the same periodsperiod of 2006,2007, is attributable to our continued identification of new Gaucher disease patients, particularly in international markets. Through October 2007, our price for Cerezyme has remained consistent from period to period. However, effectiveEffective November 1, 2007, we implemented a 3% price increase in the United States for Cerezyme. Although we expect Cerezyme to continue to be a substantial contributor to revenues in the future, it is a mature product, and as a result, we do not expect that the current new patient growth trend will continue. The strengthening of foreign currencies, primarily the Euro and British pound sterling, against the U.S. dollar, positively impacted Cerezyme revenue by $8.4$17.2 million for the three months ended and by $25.0 million for the nine months ended September 30, 2007,March 31, 2008, as compared to the same periodsperiod of 2006.2007.

                      Our results of operations are highly dependent onThe 16% increase in sales of Cerezyme and a reduction in revenue from sales of this product would adversely affect our results of operations. Sales of Cerezyme were approximately 30% of our total revenue for the three months ended September 30, 2007, as comparedFabrazyme to 31% for the same period of 2006, and 30% of our total revenue for the nine months ended September 30, 2007, as compared to 32% for the same period of 2006. Revenue from Cerezyme would be impacted negatively if competitors developed alternative treatments for Gaucher disease, and the alternative products gained commercial acceptance, if our marketing activities are restricted, or if coverage, pricing or reimbursement is limited. Although orphan drug status for Cerezyme, which provided us with exclusive marketing rights for Cerezyme in the United States for seven years, expired in May 2001, we continue to have patents protecting our method of manufacturing Cerezyme until 2010 and the composition of Cerezyme as made by that process until 2013. The expiration of market exclusivity and orphan drug status will likely subject Cerezyme to increased competition, which may decrease the amount of revenue we receive from this product or the growth of that revenue. We are aware of companies that have developed or have initiated efforts to develop competitive products, and other companies may do so in the future. We discuss these competitors under the heading "Risk Factors—Our future success will depend on our ability to effectively develop and market our products and services against those of our competitors," in this report.

                      The 12% increase to $104.6$116.5 million for the three months ended and the 18% increase to $309.6 million for the nine months ended September 30, 2007 in sales of Fabrazyme,March 31, 2008, as compared to the same periodsperiod of 2006,2007, is primarily attributable to increased patient identification worldwide as Fabrazyme is introduced into new markets. We implemented a 3% price increase in the United States for Fabrazyme in November 2007 which did not have a significant impact on Fabrazyme revenue for the three months ended March 31, 2008. The strengthening of foreign currencies, primarily the Euro and British pound sterling, against the U.S. dollar, positively impacted Fabrazyme revenue by $2.9$7.6 million for the three months ended and by $8.3 million for the nine months ended September 30, 2007,March 31, 2008, as compared to the same periods of 2006.



                      Sales of Thyrogen increased 20% to $26.8 million for the three months ended and 20% to $82.7 million for the nine months ended September 30, 2007, as compared to the same periods of 2006, due to worldwide volume growth which impacted sales by $2.7 million in the three month period and $11.5 million in the nine month period. The strengthening of foreign currencies, primarily the Euro and British pound sterling, against the U.S. dollar did not have a material impact on Thyrogen revenue for the three months ended but positively impacted Thyrogen revenue by $2.0 million for the nine months ended September 30, 2007, as compared to the same periods of 2006. We expect to receive FDA approval for the use of Thyrogen in thyroid cancer remnant ablation procedures by the end of 2007.

                      Sales of Myozyme were $53.6$67.3 million for the three months ended and $138.2March 31, 2008, as compared to $37.9 million for the nine months ended September 30, 2007, as compared to $20.4 million for the three months ended and $29.0 million for the nine months ended September 30, 2006. In March 2006, we received marketing authorization for Myozyme in the European Union. In April 2006, the FDA granted marketing approval for Myozyme in the United States.same period of 2007. We launched Myozyme in the United States in May 2006, in Europe a month later and in Canada in September 2006. We are introducing Myozyme on a country-by-country basis in the European Union, as pricing and reimbursement approvals are obtained. Myozyme has received orphan drug designation in the United States, which provides seven years of market exclusivity, and in the European Union, which provides ten years of market exclusivity. In April 2007, Myozyme was approved for commercial sale in Japan and subsequently, in June 2007, we launched the product after we receivedupon receipt of reimbursement approval. We expect to file for approval in several additional countries in 2007.2008. The 8% increase instrengthening of foreign currencies, primarily the Euro against the U.S. dollar, positively impacted Myozyme revenue by $3.5 million for the three months ended September 30, 2007, as compared to the same period of 2006, positively impacted Myozyme revenue by $1.2 million. The 8% increase in the Euro against the U.S. dollar for the nine months ended September 30, 2007, as compared to the same period of 2006, positively impacted Myozyme revenue by $1.7 million. The positive impact of the increase in the Euro against the U.S. dollar on Myozyme revenue for both the three and nine months ended September 30, 2007, is driven by the growth in sales volume of Myozyme in Europe, in each such period, as compared to the same periods of 2006.March 31, 2008.

                      We currently manufacture Myozyme in the United States at the 160 liter, or 160L, scale at our manufacturing facility in Framingham, Massachusetts and at the 2000 liter, or 2000L, scale at our manufacturing facility in Allston, Massachusetts, and have begun Myozyme fill-finish at our 2000L facility in Waterford, Ireland. We expecthave U.S. approval to commencesell Myozyme engineering runsmanufactured at our protein manufacturing facilitythe 160L scale and production at the 2000L scale has been approved for sale in Geel, Belgium later this year.more than 40 countries outside the United States.

                      In addition, in October 2007, we submitted an application to the FDA seeking approval of a larger-scale manufacturing process, based in Allston, Massachusetts, to enable usproduction at the 2000L scale to meet the expected demand for Myozyme in the U.S. market going forward. We currently anticipate a decision fromIn April 2008, the FDA concluded that Myozyme produced at the 160L scale and at the 2000L scale should be classified as two different products because of differences in the carbohydrate structures of the molecules. As a result, the FDA will require us to submit a separate BLA to gain U.S. approval for Myozyme produced at the 2000L scale. The FDA proposed that we initiate a rolling BLA review process by submitting results from our Late Onset Treatment Study, or LOTS study, for Myozyme because the Myozyme used in that study was produced at the 2000L scale. We had already been in the



              process of preparing the results of that study for submission to the FDA to fulfill a post-marketing commitment. The LOTS study, which met its co-primary efficacy endpoints, was undertaken to evaluate the safety and efficacy of Myozyme in juvenile and adult patients with Pompe disease. We expect the FDA to give the BLA priority review and to act on the application forby the end of 2008. We anticipate that this process will culminate in the availability of two commercial versions of Myozyme in the United States: one produced at the 160L scale and the other produced at the 2000L scale. This decision by the FDA will negatively impact our larger-scale manufacturing processanticipated 2008 Myozyme revenue by approximately $45 million and because we will continue to provide Myozyme to some patients through a clinical access program, we anticipate that costs related to Myozyme will be approximately $8-$10 million more than originally expected in 2008. We expect sales of Myozyme to continue to grow and expect to begin providing U.S. patients with commercial 2000L Myozyme during the first quarter of 2008.2009. In the meantime, we are continuing our efforts to optimize supply for the U.S. market.

                      Effective January 1, 2008, we, BioMarin and BioMarin/Genzyme LLC restructured our relationship regarding the manufacturing, marketing and sale of Aldurazyme and entered into several new agreements. BioMarin will continue to manufacture Aldurazyme. We will continue to purchase Aldurazyme exclusively from BioMarin and globally market including temporarily transitioning some patientsand sell the product. Effective January 1, 2008, instead of sharing all costs and profits of Aldurazyme equally, we began to record all sales of Aldurazyme and began paying BioMarin a clinical access program through which they may receive Myozyme untiltiered payment ranging from approximately 39.5% to 50% of worldwide net product sales of Aldurazyme. Aldurazyme product revenue was $36.8 million for the three months ended March 31, 2008. Prior to January 1, 2008, on behalf of BioMarin/Genzyme LLC, we were commercializing Aldurazyme in the United States, Canada, the European Union, Latin America and the Asia-Pacific regions and continuing to launch Aldurazyme on a country-by-country basis as pricing and reimbursement approvals were obtained. BioMarin/Genzyme LLC's Aldurazyme product revenue was $26.8 million for the three months ended March 31, 2007. The $10.0 million increase in sales of Aldurazyme is attributable to increased patient identification worldwide as Aldurazyme is introduced into new markets. We have applications for marketing approval for Aldurazyme currently pending in several countries in Latin America, Central and Eastern Europe and the Asia-Pacific regions.

                      Sales of Thyrogen increased 28% to $33.8 million for the three months ended March 31, 2008, as compared to the same period of 2007. A Thyrogen price increase of approximately 10% in the United States in April 2007 accounted for $1.4 million of the additional revenue while worldwide volume growth positively impacted sales by $4.3 million. The strengthening of foreign currencies, primarily the Euro against the U.S. dollar, positively impacted Thyrogen revenue by $1.9 million for the three months ended March 31, 2008, as compared to the same period of 2007. In December 2007 we received FDA approvesapproval for the larger-scale manufacturing process. Production at this larger scale is already approveduse of Thyrogen in 33 countries.

The increases are2007. This was primarily due to a $5.6$4.1 million increase forin Thymoglobulin revenue as a result of an 11% increase in the three month period and an $11.9worldwide average sales price of Thymoglobulin. In addition, there was a $2.6 million increase for the nine month period in sales of Thymoglobulin asdue to an increase in volume. This was a result of its increased utilization of Thymoglobulin in transplant procedures worldwide.

There is noFrance, which resulted in product stability issues. We have worked closely with the FDA in addressing these challenges, and have implemented process changes at our Lyon facility to resolve these production issues.

In the three months ended March 31, 2008, we have three additional finished lots of Thymoglobulin, valued at approximately $8 million, which are under review to determine whether they meet product specifications. If we determine that any of those lots do not meet the specifications for saleable product, we will write off that inventory as a charge to earnings. Even with the four finished lotsrecalled one lot of Thymoglobulin that have been written off andno longer met our specifications for product appearance. In April 2008 we recalled an additional three lots for the possibilitysame reason. The value of the unused portion of these four lots under review being written off, we currentlywas not significant. We expect to recall additional lots this year, although most of the product will likely be ableconsumed prior to meet projected market demand.a recall being necessary. We will continue to closely monitor our Thymoglobulin inventory levels and intend to manage production in order to maintain adequate supply levels throughout the remainder of 2008. We expect Thymoglobulin sales to accelerate in 2008.

In addition, we began to record Aldurazyme revenue effective January 1, 2008. Revenue generated outside the United States for Aldurazyme was $29.8 million for the three months ended March 31, 2008, which had been recorded as joint venture revenue in 2007.

                      International product and service revenue as a percentage of total product and service revenue increased due primarily to the addition of revenue generated outside the United States for Aldurazyme and clofarabine. As of January 1, 2008, we began to record revenue for Aldurazyme as a result of the restructured relationship with BioMarin/Genzyme LLC. We began recording clofarabine revenue outside the United States as a result of our acquisition of Bioenvision in October 2007 which provided us with the exclusive, worldwide rights to clofarabine.

              Selling, General and Administrative Expenses

                      Effective January 1, 2008, as a result of changes in how we review our business, certain general and administrative expenses which were formerly allocated amongst our reporting segments and Other, are now allocated to Corporate. We have revised our 2007 segment disclosures to conform to our 2008 presentation.

                        As discussed in Note 7., "Goodwill and Other Intangible Assets," to our financial statements included in this report, we calculate amortization expense for the Synvisc sales and marketing rights we reacquired from Wyeth and the Myozyme patent and technology rights acquired pursuant to a licensing agreement with Synpac by taking into account forecasted future sales of Synvisc and Myozyme, respectively,the products, and the resulting estimated future contingent payments we will be required to make to Wyeth and Synpac.make. As a result, we expect amortization of intangibles expense to fluctuate over the next five years based on these future contingent payments.

                Charge for Impaired Goodwill

                        We are required to perform impairment tests related to our goodwill under FAS 142 annually and whenever events or changes in circumstances suggest that the carrying value of an asset may not be recoverable. We completed the required annual impairment tests for our $1.3 billion of net goodwill in the third quarter of 2007 and determined that no impairment charges were required.

                        As a result of the required annual impairment tests we performed on our $1.5 billion of net goodwill in the third quarter of 2006, we determined that the $219.2 million of goodwill assigned to our Genetics reporting unit was fully impaired and we recorded a pre-tax impairment charge of $219.2 million and $69.8 million of related tax benefits in September 2006.


                Purchase of In-Process Research and Development

                        In connection with fivecertain of our acquisitions we completed between January 1, 20042006 and September 30,December 31, 2007, we have acquired various IPR&D projects. Substantial additional research and development costs will be required prior to any of our acquired IPR&D programs and technology platforms reaching technological feasibility. In addition, once research is completed, each product candidate acquired will need to complete a series of clinical trials and receive FDA or other regulatory approvals prior to commercialization. Our current estimates of the time and investment required to develop these



                products and technologies may change depending on the different applications that we may choose to pursue. We cannot give assurances that these programs will ever reach technological feasibility or develop into products that can be marketed profitably. In addition, we cannot guarantee that we will be able to develop and commercialize products before our competitors develop and commercialize products for the same indications. If products based on our acquired IPR&D programs and technology platforms do not become commercially viable, our results of operations could be materially adversely affected. We did not complete any acquisitions in the three months ended March 31, 2008.

                Management assumes responsibility for determining the valuation of the acquired IPR&D projects. The fair value assigned to IPR&D for each acquisition is estimated by discounting, to present value, the cash flows expected once the acquired projects have reached technological feasibility. The cash flows are probability-adjusted to reflect the risks of advancement through the product approval process. In estimating the future cash flows, we also considered the tangible and intangible assets required for successful exploitation of the technology resulting from the purchased IPR&D projects and adjusted future cash flows for a charge reflecting the contribution to value of these assets.

                (2)
                IPR&D charges totaled $125.5 million related to the acquisition of Bioenvision, of which $106.4 million was charged to IPR&D and $19.1 million was charged to equity in income (loss) of equity method investments.

                Campath is currently marketed for the treatment ofB-cell chronic lymphoeytic leukemia and Clolar is marketed for the treatment of relapsed and refractory pediatric ALL. The IPR&D projects for Campath and Clolar are related to the development of these products for the treatment of other medical issues.

                        In addition, we account for our investment in Bioenvision Common Stock under the equity method of accounting and, accordingly, we recorded a charge of $19.1 million in equity in income (loss) of equity method investments in our consolidated statement of operations for the three and nine months ended September 2007 for the portion of the purchase price for this investment that we allocated to IPR&D. The full purchase accounting for our acquisition of Bioenvision, including the impact of our merger in October 2007, will be reflected in our consolidated financial statements as of December 31, 2007 and for the year ended December 31, 2007.

                Our effective tax rate for all periods presented varies from the U.S. statutory tax rate as a result of:

                  our provision for state income taxes;

                  the tax benefits from export sales;

                  the tax benefits from domestic productionmanufacturing activities;

                  benefits related to tax credits;

                  income and expenses taxed at rates other than the U.S. statutory tax rate; and

                  non-deductible stock-based compensation expenses; and

                  non-deductible expenses associated with the settlement of litigation related to the consolidation of our former tracking stocks.

                Our effective tax rate$8.1 million for the three and nine months ended September 30, 2006, was also impacted by a charge for impaired goodwill of $219.2March 31, 2008 and $6.9 million of which $29.5 million was not deductible for tax purposes.

                        Effective January 1, 2007, we adopted FIN 48 and recognized a cumulative effect adjustment of $33.9 million to increase our retained earnings balance as of January 1, 2007, which consisted of $25.8 million to record the combined effect of our gain contingency and the change in the recognition standard pursuant to the settlement criteria of FSP FIN 48-1 and $8.1 million resulting from our settlement of the IRS audit for tax years 2002 to 2003. After these adjustments, as of January 1, 2007, we had approximately $36.5 million of total gross unrealized tax benefits, of which approximately $26.6 million represents the amount of unrecognized tax benefits that, if recognized, would favorably affect our effective income tax rate in future periods. These gross unrealized tax benefits did not change significantly during the nine months ended September 30, 2007.

                        We continue to recognize interest relating to unrecognized tax benefits within our provision for income taxes but have not recorded any amounts related to potential penalties. The amount of accrued interest related to unrecognized tax benefits within our provision for income taxes for the three and nine months ended September 30, 2007 and our accrued interest related to unrecognized tax benefits as of January 1, 2007 and September 30, 2007 were not significant.

                March 31, 2007.

                        We are subject to U.S. federal income tax and various state, local and international income taxes in numerous jurisdictions, however, our only significant tax jurisdiction is the United States. We record liabilities for income tax contingencies based on our best estimate of the underlying exposures.        We are currently under IRS audit for tax years 2004 to 2005 and in certain state and foreign jurisdictions from 2003 forward.various states for 1999 to 2005. We believe that we have provided sufficiently for all audit exposuresexposures. We expect to settle the 2004 to 2005 IRS audit within the next twelve months and assessments.do not expect that the settlement will have a



                material impact on our financial position or results of operations. Settlement of these audits or the expiration of the statute of limitations on the assessment of income taxes for any tax year may result in an increase ora reduction of future tax provisions. Any such tax or tax benefit would be recorded upon final resolutionthe effective settlement of the auditsaudit or expiration of the applicable statute of limitations.

                        Management has concluded that it is not reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within the next 12 months.

                  a $13.6 million decrease in gains on investments in equity securities; and

                    Contractual Obligations

                            The disclosure of payments we have committed to make under our contractual obligations is set forth under the heading "Management's Discussion and Analysis of Genzyme Corporation and Subsidiaries' Financial Condition and Results of Operations—Liquidity and Capital Resources" in Exhibit 13 to our 20062007 Form 10-K. Excluding additional contingent payments to Wyeth for the reacquisitionAs of the Synvisc sales and marketing rights as of September 30, 2007March 31, 2008, there have been no material changes to our contractual obligations since December 31, 2006.2007.

                    Financial Position

                            We believe that our available cash, investments and cash flows from operations will be sufficient to fund our planned operations and capital requirements for the foreseeable future. Although we currently have substantial cash resources and positive cash flow, we have used or intend to use substantial portions of our available cash and may make additional borrowings for:

                      product development and marketing;

                      payments related to the cash consideration for our merger withdue to the dissenting Bioenvision includingshareholders, the approximately $245 millionamount of cash we paid in October 2007 upon completionwhich will be determined by the Delaware Court of the merger, the approximately $11 million of cash we intend to pay in the fourth quarter of 2007 for the outstanding options to purchase shares of Bioenvision Common Stock;Chancery;

                      other business combinations and strategic business initiatives, including the approximately $53 million in Canadian dollars, or approximately $57 million in U.S. dollars (based on the November 2, 2007 spot rate for the Canadian dollar), of cash we intend to spend in December 2007 for our planned acquisition of the diagnostics division of DCL;initiatives;

                      the remaining $1.2 billion approved for our $1.5 billionongoing stock repurchase program;program over approximately the next 2 years;

                      expanding existing and constructing additionalnew manufacturing facilities;

                      upgrading our information technology systems;

                      contingent payments under license and other agreements;agreements, including payments related to our license of mipomersen from Isis;

                      expanding staff; and

                      working capital and satisfaction of our obligations under capital and operating leases.

                              Our cash reserves may be further reduced to pay principal and interest on the $690.0 million in principal under our 1.25% convertible senior notes due December 1, 2023. The notes are initially convertible into Genzyme Stock at a conversion price of approximately $71.24 per share. Holders of the notes may require us to repurchase all or any part of the notes for cash, common stock, or a combination, at our option, on December 1, 2008, 2013 or 2018, at a price equal to 100% of the principal amount of the notes plus accrued and unpaid interest through the date prior to the date of repurchase. Additionally, upon a change of control, each holder may require us to repurchase, for cash, at 100% of the principal amount of the notes plus accrued interest, all or a portion of the holder's notes.notes for cash. On or after December 1, 2008, we may redeem for cash at 100% of the principal amount of the notes plus accrued interest, all or part of the notes that have not been previously converted or repurchased.

                              In addition, we have several outstanding legal proceedings. Involvement in investigations and litigation can be expensive and a court may ultimately require that we pay expenses and damages. As a result of legal proceedings, we also may be required to pay fees to a holder of proprietary rights in order to continue certain operations. We have provided you details on one set of pending legal proceedings in the notes to our consolidated financial statements.



                              To satisfy these and other commitments, we may have to obtain additional financing. We cannot guarantee that we will be able to obtain any additional financing, extend any existing financing arrangement, or obtain either on favorable terms.

                      Off-Balance Sheet Arrangements

                              We do not use special purpose entities or other off-balance sheet financing arrangements. We enter into guarantees in the ordinary course of business related to the guarantee of our own performance and the performance of our subsidiaries. In addition, we have joint ventures and certain other arrangements that are focused on research, development, and the commercialization of products. Entities falling within the scope of FIN 46R are included in our consolidated statements of operations if we qualify as the primary beneficiary. Entities not subject to consolidation under FIN 46R are accounted for under the equity method of accounting if our ownership percent exceeds 20% or if we exercise significant influence over the entity. We account for our portion of the income/lossesresults of these entities in the line item "Equity in income (loss) of equity method investments" in our consolidated statements of operations. We also acquire companies in which we agree to pay contingent consideration based on attaining certain thresholds.

                      Recent Accounting Pronouncements

                      FAS 157, "Fair Value Measurements." In September 2006, the FASB issued FAS 157, "Fair Value Measurements," which provides enhanced guidance for using fair value to measure assets and liabilities. FAS 157 establishes a common definition of fair value, provides a framework for measuring fair value under accounting principles generally accepted in the United States and expands disclosure requirements regarding fair value measurements. FAS 157 will be effective for us as of January 1, 2008. We are currently evaluating the impact, if any, the adoption of FAS 157 will have on our financial position and results of operations.

                      FAS 159, "The Fair Value Option for Financial Assets and Financial Liabilities—Liabilities, Including an Amendment of FASB Statement No. 115."    In February 2007, the FASB issuedEffective January 1, 2008, we adopted FAS 159, "The Fair Value Option for Financial Assets and Financial Liabilities—Liabilities, Including an Amendment of FASB Statement No. 115," which permits, but does not require, entitiesus to measure certain financial instruments and other assets and liabilities at fair value on an instrument-by-instrument basis. Unrealized gains and losses on items for which the fair value option has been elected should beare recognized in earnings at each subsequent reporting date. In adopting FAS 159, we did not elect to measure any new assets or liabilities at their respective fair values and, therefore, the adoption of FAS 159 did not have an impact on our results of operations or financial position.


                              EITF Issue No. 07-1, "Accounting for Collaborative Arrangements."    In December 2007, the EITF of the FASB reached a consensus on Issue No. 07-1, "Accounting for Collaborative Arrangements." The EITF concluded on the definition of a collaborative arrangement and that revenues and costs incurred with third parties in connection with collaborative arrangements would be presented gross or net based on the criteria in EITF 99-19 and other accounting literature. Companies are also required to disclose the nature and purpose of collaborative arrangements along with the accounting policies and the classification and amounts of significant financial-statement amounts related to the arrangements. EITF 07-1 will bebecome effective for us beginning January 1, 2009 and will be applied retrospectively to all periods presented for all collaborative arrangements existing as of January 1, 2008 and cannot be adopted early unless FAS 157 is also adopted.the effective date. We are currently evaluating the impact, if any, the adoption of FAS 159this standard will have on our consolidated financial position and results of operations.statements.

                      EITF Issue No. 07-3, "Accounting "Accounting for Nonrefundable Advance Payments for Goods or Services Received for Use in Future Research and Development Activities.""    In June 2007, the FASB ratified the EITF consensus reached in EITF Issue No. 07-3, "Accounting for Nonrefundable Advance Payments for Goods or Services Received for Use in Future Research and Development Activities," which provides guidance for nonrefundable prepayments for goods or services that will be used or rendered for future research and development activities and directs that such payments should be deferred and capitalized. Such amounts should be recognized as an expense as the goods are delivered or the related services are performed, or until it is no longer expected that the goods will be delivered or the services rendered. EITF 07-3 iswas effective for us beginning January 1, 2008 and will bewe applied it prospectively to new contracts we enterentered into on or after that date. Earlier application isThe implementation of this standard did not permitted. We are currently evaluating thehave a material impact if any, the adoption of EITF No. 07-3 will have on our financial position, results of operations or cash flows.

                              FAS 141 (revised 2007), "Business Combinations."    In December 2007, the FASB issued FAS 141 (revised 2007), "Business Combinations," or FAS 141R, which replaces FAS 141, "Business Combinations." FAS 141R retains the underlying concepts of FAS 141 in that all business combinations are still required to be accounted for at fair value under the acquisition method of accounting but changes a number of significant aspects of applying this method. Acquisition costs will generally be expensed as incurred; noncontrolling interests will be valued at fair value at the acquisition date; IPR&D will be recorded at fair value as an indefinite-lived intangible asset at the acquisition date; restructuring costs associated with a business combination will generally be expensed subsequent to the acquisition date; and changes in deferred tax asset valuation allowances and income tax uncertainties after the acquisition date generally will affect income tax expense. FAS 141R is effective for us on a prospective basis for all business combinations for which the acquisition date is on or after January 1, 2009. Early adoption is not permitted. We are currently evaluating the effects, if any, that FAS 141R will have on our consolidated financial statements.

                              FAS No. 160, "Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51."    In December 2007, the FASB issued FAS 160, "Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51," which establishes new accounting and reporting standards that require the ownership interests in subsidiaries not held by the parent company to be clearly identified, labeled and presented in the consolidated statement of financial position within equity, but separate from the parent's equity. FAS 160 also requires the amount of consolidated net income attributable to the parent and to the non-controlling interest, commonly referred to as the minority interest, to be clearly identified and presented on the face of the consolidated statement of income. Changes in a parent's ownership interest while the parent retains its controlling financial interest must be accounted for consistently, and when a subsidiary is deconsolidated, any retained non-controlling equity investment in the former subsidiary must be initially measured at fair value. The gain or loss on the deconsolidation of the subsidiary is measured using the fair value of any non-controlling equity investment. FAS 160 also requires entities to provide sufficient disclosures that clearly identify and distinguish between the interests of the parent and the interests of the non-controlling owners. FAS 160 is effective for us beginning January 1, 2009 and adoption is



                      prospective only; however, upon adoption, presentation and disclosure requirements described above must be applied retrospectively for all periods presented in our consolidated financial statements. We are currently evaluating the effects, if any, that FAS 160 will have on our consolidated financial statements.

                              FAS No. 161, "Disclosures About Derivative Instruments and Hedging Activities—an amendment of FASB Statement No. 133."    In March 2008, the FASB issued FAS 161, "Disclosures about Derivative Instruments and Hedging Activities, an amendment of FASB Statement No. 133," which amends and expands the disclosure requirements of FAS 133, "Accounting for Derivative Instruments and Hedging Activities." FAS 161 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. FAS 161 is effective prospectively for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. We are currently evaluating the effects, if any, that FAS 161 will have on our consolidated financial statements.


                      RISK FACTORS

                              Our future operating results could differ materially from the results described in this report due to the risks and uncertainties related to our business, including those discussed below.

                      Our financial results are highly dependent on sales of Cerezyme.

                              We generate a significant portion of our revenue from sales of Cerezyme, our enzyme-replacement product for patients with Gaucher disease. Sales of Cerezyme totaled $832.8 million for the nine months ended September 30, 2007, representing approximately 30% of our consolidated total revenue. Because our business is highly dependent on Cerezyme, negative trends in revenue from this product could have a significant adverse effect on our results of operations and cause the value of our securities to decline substantially. We will lose revenue if alternative treatments gain commercial acceptance, if our marketing activities are restricted, or if reimbursement is limited. In addition, the patient population with Gaucher disease is not large. Because a significant percentage of that population already uses Cerezyme, opportunities for future sales growth are constrained. Furthermore, changes in the methods for treating patients with Gaucher disease, including treatment protocols that combine Cerezyme with other therapeutic products or reduce the amount of Cerezyme prescribed, could limit growth, or result in a decline, in Cerezyme sales.

                      If we fail to increase sales of several existing products and services, we will not meet our financial goals.

                              Over the next few years, our success will depend substantially on our ability to increase revenue from our existing products and services. These products and services include Renagel, Renvela, Synvisc, Synvisc-One, Fabrazyme, Myozyme, Hectorol, Thymoglobulin, Thyrogen, Clolar, Campath, Aldurazyme and diagnostic testing services. Our ability to increase sales will depend on a number of factors, including:

                        acceptance by the medical community of each product or service;

                        the availability of competing treatments that are deemed safer, more efficacious, more convenient to use, or more cost effective;

                        our ability, and the ability of our collaborators, to efficiently manufacture sufficient quantities of each product to meet demand and to do so in a cost efficient manner;

                        regulation by the U.S. Food and Drug Administration, commonly referred to as the FDA, and the European Agency for the Evaluation of Medicinal Products, or EMEA, and other regulatory authorities of these products and the facilities and processes used to manufacture these products;

                        the scope of the labeling approved by regulatory authorities for each product and competitive products;

                        the effectiveness of our sales force;

                        the availability and extent of coverage, pricing and level of reimbursement from governmental agencies and third party payors; and

                        the size of the patient population for each product or service and our ability to identify new patients.

                              Part of our growth strategy involves conducting additional clinical trials to support approval of expanded uses of some of our products, including Clolar and alemtuzumab, pursuing marketing approval for our products in new jurisdictions and developing next generation products such as Renvela



                      and Synvisc-One. The success of this component of our growth strategy will depend on the outcome of



                      these additional clinical trials, the content and timing of our submissions to regulatory authorities and whether and when those authorities determine to grant approvals.

                              Because the healthcare industry is extremely competitive and regulatory requirements are rigorous, we spend substantial funds marketing our products and attempting to expand approved uses for them. These expenditures depress near-term profitability, with no assurance that the expenditures will generate future profits that justify the expenditures.

                      Our future success will depend on our ability to effectively develop and market our products and services against those of our competitors.

                              The human healthcare products and services industry is extremely competitive. Other organizations, including pharmaceutical, biotechnology, device and diagnostic testing companies, have developed and are developing products and services to compete with our products, services, and product candidates. If healthcare providers, patients or payors prefer these competitive products or services or these competitive products or services have superior safety, efficacy, pricing or reimbursement characteristics, we will have difficulty maintaining or increasing the sales of our products and services.

                              Renagel competes with two other products approved in the United States for the control of elevated phosphorus levels in patients with chronic kidney failure on hemodialysis. Fresenius Medical Care markets PhosLo®, a calcium-based phosphate binder. Shire Pharmaceuticals Group plc, or Shire, markets Fosrenol®, a non-calcium based phosphate binder. Amgen, Inc. recently acquired Ilypsa and its product candidate, ILY101, a polymeric phosphate binder that completed a phase 2 trial in CKD patients on dialysis. Renagel also competes with over-the-counter calcium carbonate products such as TUMS® and metal-based options such as aluminum and magnesium.

                              UCB S.A. has developed Zavesca®, a small molecule drug for the treatment of Gaucher disease, the disease addressed by Cerezyme. Zavesca, sold by Actelion Ltd., has been approved in the United States, European Union and Israel as an oral therapy for use in patients with mild to moderate Type 1 Gaucher disease for whom enzyme replacement therapy is unsuitable. In addition, Shire reported top-line data from a phase 1/2 clinical trial for its gene-activated glucocerebrosidase program, also to treat Gaucher disease, and initiated phase 3 studies in July 2007. Protalix Biotherapeutics Ltd. initiated a phase 3 trial for plant-derived enzyme replacement therapy to treat Gaucher disease in the third quarter of 2007. Amicus Therapeutics, Inc., or Amicus, is conducting phase 2 trials for oral chaperone medication to treat Gaucher disease. We are also aware of other development efforts aimed at treating Gaucher disease.

                              Outside the United States, Shire is marketing Replagal™, a competitive enzyme replacement therapy for Fabry disease which is the disease addressed by Fabrazyme. In addition, while Fabrazyme has received orphan drug designation, which provides us with seven years of market exclusivity for the product in the United States, other companies may seek to overcome our market exclusivity and, if successful, compete with Fabrazyme in the United States. Amicus has initiated phase 2 trials for an oral chaperone medication to treat Fabry disease. We are aware of other development efforts aimed at treating Fabry disease.

                              Current competition for Synvisc and Synvisc-One includes Supartz®, a product manufactured by Seikagaku KogyoCorporation that is sold in the United States by Smith & Nephew Orthopaedics and in Japan by Kaken Pharmaceutical Co. under the name Artz®; Hyalgan®, produced by Fidia Farmaceutici S.p.A. and marketed in the United States by Sanofi-Aventis; Orthovisc®, produced by Anika Therapeutics, Inc., and marketed in the United States by Johnson & JohnsonJohnson's Mitek division and marketed outside the United States through distributors; Euflexxa™, a product manufactured and sold by Ferring Pharmaceuticals and marketed in the United States and Europe; and Durolane®,



                      manufactured by Q-Med AB and distributed outside the United States by Smith & Nephew Orthopedics. Durolane and Euflexxa are produced by bacterial fermentation, which may provide these products a competitive advantage over avian-sourced Synvisc and Synvisc-One. We are aware of various viscosupplementation products on the market or in development, but are unaware of any products that


                      have physical properties of viscosity, elasticity or molecular weight comparable to those of Synvisc.Synvisc and Synvisc-One. Furthermore, several companies market products that are not viscosupplementation products but which are designed to relieve the pain associated with osteoarthritis. Synvisc and Synvisc-One will have difficulty competing with any of these products to the extent the competitive products are considered more efficacious, less burdensome to administer or more cost-effective.

                              Myozyme has marketing exclusivity in the United States until 2013 and in the European Union until 2016 due to its orphan drug status. Amicus Therapeutics has completed two phase 1 clinical studies for a small molecule treatment for Pompe disease and has announced their plans to initiate a phase 2 clinical trial in early 2008.

                      Several companies market products that, like Thymoglobulin, and Lymphoglobuline, are used for the prevention and treatment of acute rejection in renal transplant. These products include Novartis' Simulect® and Pfizer Inc.'s ATGAM®. Competition in the acute transplant rejection market is driven largely by product efficacy due to the potential decreased long-term survival of transplanted organs as the result of an acute organ rejection episode.

                              The examples above are illustrative and not exhaustive. Almost all of our products and services face competition. Furthermore, the field of biotechnology is characterized by significant and rapid technological change. Discoveries by others may make our products or services obsolete. For example, competitors may develop approaches to treating LSDs that are more effective, convenient or less expensive than our products and product candidates. Because a significant portion of our revenue is derived from products that address this class of diseases and a substantial portion of our expenditures is devoted to developing new therapies for this class of diseases, such a development would have a material negative impact on our results of operations.

                      If we fail to obtain and maintain adequate levels of reimbursement for our products from third party payors, the commercial potential of our products will be significantly limited.

                              A substantial portion of our domestic and international revenue comes from payments by third party payors, including government health administration authorities and private health insurers. Governments and other third party payors may not provide adequate insurance coverage or reimbursement for our products and services, which could impair our financial results.

                              Third party payors are increasingly scrutinizing pharmaceutical budgets and healthcare expenses and are attempting to contain healthcare costs by:

                        challenging the prices charged for healthcare products and services;

                        limiting both the coverage and the amount of reimbursement for new therapeutic products;

                        reducing existing reimbursement rates for commercialized products and services;

                        limiting coverage for the treatment of a particular patient to a maximum dollar amount or specified period of time;

                        denying or limiting coverage for products that are approved by the FDA or other governmental regulatory bodies but are considered experimental or investigational by third party payors; and

                        refusing in some cases to provide coverage when an approved product is used for disease indications in a way that has not received FDA or other applicable marketing approval.

                                Attempts by third party payors to reduce costs in any of these ways could decrease demand for our products. In addition, in certain countries, including countries in the European Union and Canada, the coverage of prescription drugs, the pricing, and the level of reimbursement are subject to governmental control. Therefore, we may be unable to negotiate coverage, pricing and/or reimbursement on terms that are favorable to us. Government health administration authorities may also rely on analyses of the cost-effectiveness of certain therapeutic products in determining whether to provide reimbursement for such products. Our ability to obtain satisfactory pricing and reimbursement may depend in part on whether our products, the cost of some of which is high in comparison to other therapeutic products, are viewed as cost-effective.


                                Furthermore, governmental regulatory bodies, such as the Centers for Medicare and Medicaid Services (CMS), may from time-to-time make unilateral changes to reimbursement rates for our products and services. These changes could reduce our revenues by causing healthcare providers to be less willing to use our products and services. Although we actively seek to assure that any initiatives that are undertaken by regulatory agencies involving reimbursement for our products and services do not have an adverse impact on us, we may not always be successful in these efforts. For example, in October 2006, the CMS announced a change to the billing code for viscosupplementation products effective January 2007 that, if unchanged, would have resulted in Medicare reimbursement for Synvisc at a rate that was lower than the price healthcare providers were paying for the product. In December 2006, the CMS reversed its decision. If the CMS billing code decision had been left unchanged, our Synvisc revenues would have been adversely affected because healthcare providers likely would have been less willing to use Synvisc. Although the CMS ultimately reversed its decision and left the mechanism for calculating Synvisc reimbursement in 2007 substantially similar to the reimbursement mechanism for 2006, we have no way of knowing whether, at some point in the future, the CMS will change the method for reimbursing Synvisc or any of our other products and services in a way that could have an adverse effect on our revenues.

                        The development of new biotechnology products involves a lengthy and complex process, and we may be unable to commercialize any of the products we are currently developing.

                                We have numerous products under development and devote considerable resources to research and development, including clinical trials.

                                Before we can commercialize our development-stage product candidates, we will need to:

                          conduct substantial research and development;

                          undertake preclinical and clinical testing;

                          develop and scale-up manufacturing processes; and

                          pursue marketing approvals and, in some jurisdictions, pricing and reimbursement approvals.

                                This process involves a high degree of risk and takes many years. Our product development efforts with respect to a product candidate may fail for many reasons, including:

                          failure of the product candidate in preclinical studies;

                          difficulty enrolling patients in clinical trials, particularly for disease indications with small patient populations;

                          patients exhibiting adverse reactions to the product candidate or indications of other safety concerns;

                          insufficient clinical trial data to support the effectiveness of the product candidate;

                          our inability to manufacture sufficient quantities of the product candidate for development or commercialization activities in a timely and cost-efficient manner;

                          our failure to obtain the required regulatory approvals for the product candidate, the facilities or the process used to manufacture the product candidate; or

                          changes in the regulatory environment, including pricing and reimbursement, that make development of a new product or indication no longer desirable.

                                Few research and development projects result in commercial products, and success in preclinical studies or early clinical trials often is not replicated in later studies. For example, in our phase 3 trial known as the Polymer Alternative for CDAD treatment (PACT) study, tolevamer did not meet its


                        primary endpoint. In our pivotal study of hylastan for treatment of patients with osteoarthritis of the



                        knee, hylastan did not meet its primary endpoint. We may decide to abandon development of a product or service candidate at any time or we may be required to expend considerable resources repeating clinical trials or conducting additional trials, either of which would increase costs of development and delay any revenue from those product candidates.

                                Our efforts to expand the approved indications for our products and to gain marketing approval in new jurisdictions and to develop next generation products also may fail. These expansion efforts are subject to many of the risks associated with completely new products and accordingly, we may fail to recoup the investments we make pursuing these strategies.

                        Our financial results are dependent on sales of Cerezyme.

                                Sales of Cerezyme, our enzyme-replacement product for patients with Gaucher disease, totaled $304.3 million for the three months ended March 31, 2008, representing approximately 28% of our total revenue. Because our business is dependent on Cerezyme, negative trends in revenue from this product could have an adverse effect on our results of operations and cause the value of our securities to decline. We will lose revenue if alternative treatments gain commercial acceptance, if our marketing activities are restricted, or if coverage, pricing or reimbursement is limited. In addition, the patient population with Gaucher disease is not large. Because a significant percentage of that population already uses Cerezyme, opportunities for future sales growth are constrained. Furthermore, changes in the methods for treating patients with Gaucher disease, including treatment protocols that combine Cerezyme with other therapeutic products or reduce the amount of Cerezyme prescribed, could limit growth, or result in a decline, in Cerezyme sales.

                        We may encounter substantial difficulties managing our growth.

                                Several risks are inherent to our plans to grow our business. Achieving our goals will require substantial investments in research and development, sales and marketing, and facilities. For example, we have spent considerable resources building and seeking regulatory approvals for our manufacturing plants. We cannot assure you that these facilities will prove sufficient to meet demand for our products or that we will not have excess capacity at these facilities. In addition, building our facilities is expensive, and our ability to recover these costs will depend on increased revenue from the products produced at the facilities.

                                We produce relatively small amounts of material for research and development activities and pre-clinical trials. Even if a product candidate receives all necessary approvals for commercialization, we may not be able to successfully scale-up production of the product material at a reasonable cost or at all.all and we may not receive manufacturing approvals in sufficient time to meet product demand. For example, the FDA has concluded that Myozyme produced in our 2000 liter bioreactors is a different product than Myozyme produced in our 160 liter bioreactors and is therefore requiring us to submit a separate BLA for the 2000 liter Myozyme. This delay in receipt of FDA approval has had an adverse effect on our revenues and earnings and will continue to have an adverse effect until we receive regulatory approval.

                                If we are able to grow sales of our products, we may have difficulty managing inventory levels. Marketing new therapies is a complicated process, and gauging future demand is difficult. With Renagel, for example, we have encountered problems in the past managing inventory levels at wholesalers. Comparable problems may arise with any of our products, particularly during market introduction.


                                Growth in our business may also contribute to fluctuations in our operating results, which may cause the price of our securities to decline. Our revenue may fluctuate due to many factors, including changes in:

                          wholesaler buying patterns;

                          reimbursement rates;

                          physician prescribing habits;

                          the availability or pricing of competitive products; and

                          currency exchange rates.

                                We may also experience fluctuations in our quarterly results due to price changes and sales incentives. For example, purchasers of our products, particularly wholesalers, may increase purchase orders in anticipation of a price increase and reduce order levels following the price increase. We occasionally offer sales incentives and promotional discounts on some of our products and services that could have a similar impact. In addition, some of our products, including Synvisc, are subject to seasonal fluctuation in demand.



                        Our operating results and financial position may be impacted when we attempt to grow through business combination transactions.

                                We may encounter problems assimilating operations acquired in business combination transactions. These transactions often entail the assumption of unknown liabilities, the loss of key employees, and the diversion of management attention. Furthermore, in any business combination, including our acquisitionsacquisition of AnorMED Inc. and Bioenvision, there is a substantial risk that we will fail to realize the benefits we anticipated when we decided to undertake the transaction. We have in the past taken significant charges for impaired goodwill and for impaired assets acquired in business combination transactions. We may be required to take similar charges in the future.

                        Manufacturing problems may cause product launch delays, inventory shortages, recalls and unanticipated costs.

                                In order to generate revenue from our approved products, we must be able to produce sufficient quantities of the products. Many of our products are difficult to manufacture. Our products that are biologics, for example, require product characterization steps that are more onerous than those required for most chemical pharmaceuticals. Accordingly, we employ multiple steps to attempt to control the manufacturing processes. Minor deviations in these manufacturing processes could result in unacceptable changes in the products that result in lot failures, product recalls, product liability claims and insufficient inventory. For example, we have experienced manufacturing issues with Thymoglobulin that resulted in write offs or recalls of lots produced in 2007 that went out of specification prior to expiry.

                                Certain of the raw materials required in the commercial manufacturing and the formulation of our products are derived from biological sources, including mammalian sources and human plasma. Such raw materials may be subject to contamination or recall. Also, some countries in which we market our products may restrict the use of certain biologically derived substances in the manufacture of drugs. A material shortage, contamination, recall, or restriction of the use of certain biologically derived substances in the manufacture of our products could adversely impact or disrupt our commercial manufacturing of our products or could result in a mandated withdrawal of our products from the market. This too, in turn, could adversely affect our ability to satisfy demand for our products, which could materially and adversely affect our operating results.

                                In addition, we may only be able to produce certainsome of our products at a very limited number of facilities and, in some cases, we rely on third parties to formulate and manufacture our products. For example, we manufacture all of our Cerezyme and a portion of our Fabrazyme and Myozyme products



                        at our facility in Allston, Massachusetts. A number of factors could cause production interruptions at our facilities or the facilities of our third party providers, including equipment malfunctions, labor problems, natural disasters, power outages, terrorist activities, or disruptions in the operations of our suppliers.

                                Manufacturing is also subject to extensive government regulation. Regulatory authorities must approve the facilities in which human healthcare products are produced and those facilities are subject to ongoing inspections. In addition, changes in manufacturing processes may require additional regulatory approvals. Obtaining and maintaining these regulatory approvals could cause us to incur significant additional costs and lose revenue. For example, we are currently working with the FDA to obtain approval of a larger-scale Myozyme manufacturing process. We anticipate a decision from the FDA in the first quarter of 2008 and, until that time, are taking actions to optimize our U.S. Myozyme supply, including making Myozyme available to some patients through a clinical access program. Furthermore, any third party we use to manufacture, fill-finish or package our products to be sold must also be licensed by the applicable regulatory authorities. As a result, alternative third party providers may not be readily available on a timely basis.

                                Additionally, we determined that four lots of Thymoglobulin finished goods inventory did not meet our internal specifications for saleable product which caused those lots to be written off. Currently, we



                        have three additional finished lots of Thymoglobulin, valued at approximately $8 million, which are under review to determine whether they meet product specifications. If we determine that any of those lots do not meet the specifications for saleable product, we will write off that inventory as a charge to earnings. Even with the four finished lots of Thymoglobulin that have been written off and the possibility of lots under review being written off, we currently expect to be able to meet projected market demand. We will continue to closely monitor our inventory levels and intend to manage production to maintain adequate supply levels in 2008.

                        Guidelines and recommendations published by various organizations can reduce the use of our products.

                                Professional societies, practice management groups, private health/science foundations, and organizations involved in various diseases may publish guidelines or recommendations to the healthcare and patient communities from time to time. Recommendations of government agencies or these other groups/organizations may relate to such matters as usage, dosage, route of administration, cost-effectiveness, and use of related therapies. Organizations like these have in the past made recommendations about our products and products of our competitors. Recommendations or guidelines that are followed by patients and healthcare providers could result in decreased use of our products. The perception by the investment community or shareholders that recommendations or guidelines will result in decreased use of our products could adversely affect prevailing market price for our common stock. In addition, our success also depends on our ability to educate patients and healthcare providers about our products and their uses. If these education efforts are not effective, then we may not be able to increase the sales of our existing products or successfully introduce new products to the market.

                        We rely on third parties to provide us with materials and services in connection with the manufacture of our products.

                                CertainSome materials necessary for commercial production of our products, including specialty chemicals and components necessary for manufacture, fill-finish and packaging, are provided by unaffiliated third party suppliers. In some cases, such materials are specifically cited in our marketing application with regulatory authorities so that they must be obtained from that specific source unless and until the applicable authority approvedapproves another supplier. In addition, there may only be one available source for a particular chemical or component. For example, we acquire polyalylamine (PAA), used in the manufacture of Renagel, Renvela, Cholestagel and WelChol, from Cambrex Charles City, Inc., the only source for this material currently qualified in our FDA drug applications for these products. Our suppliers also may be subject to FDA regulations or the regulations of other governmental agencies outside the United States regarding manufacturing practices. We may be unable to manufacture our products in a timely manner or at all if these third party suppliers were to cease or interrupt production or otherwise fail to supply these materials or products to us for any reason, including due to regulatory requirements or actions, adverse financial developments at or affecting the supplier, or labor shortages or disputes.

                                We also source some of our manufacturing, fill-finish, packaging and distribution operations to third party contractors. The manufacture of products, fill-finish, packaging and distribution of our products requires successful coordination among these third party providers and Genzyme. Our inability to coordinate these efforts, the inability of the third party contractor to secure sufficient source materials, the lack of capacity available at a third party contractor or any other problems with the operations of these third party contractors could require us to delay shipment of saleable products,



                        recall products previously shipped or could impair our ability to supply products at all. This could increase our costs, cause us to lose revenue or market share and damage our reputation.



                        If our strategic alliances are unsuccessful, our operating results will be negatively impacted.

                                Several of our strategic initiatives involve alliances with other biotechnology and pharmaceutical companies, including a joint venture with BioMarin Pharmaceutical Inc. with respect to Aldurazyme. The success of these and similar arrangements is largely dependent on technology and other intellectual property contributed by our strategic partners or the resources, efforts, and skills of our partners. Disputes and difficulties in such relationships are common, often due to conflicting priorities or conflicts of interest. Merger and acquisition activity may exacerbate these conflicts. The benefits of these alliances are reduced or eliminated when strategic partners:

                          terminate the agreements or limit our access to the underlying intellectual property;

                          fail to devote financial or other resources to the alliances and thereby hinder or delay development, manufacturing or commercialization activities;

                          fail to successfully develop, manufacture or commercialize any products; or

                          fail to maintain the financial resources necessary to continue financing their portion of the development, manufacturing, or commercialization costs of their own operations.

                                Furthermore, payments we make under these arrangements may exacerbate fluctuations in our financial results. In addition, under some of our strategic alliances, we make milestone payments well in advance of commercialization of products with no assurance that we will ever recoup these payments. We also may make equity investments in our strategic partners, as we did with RenaMed Biologics, Inc., or RenaMed, in June 2005. Our strategic equity investments are subject to market fluctuations, access to capital and other business events, such as initial public offerings, the completion of clinical trials and regulatory approvals, which can impact the value of these investments. For example, in October 2006, RenaMed suspended clinical trials of its renal assist device which was being developed to treat patients with acute renal failure, causing us to write off our entire investment in RenaMed. If any of our other strategic equity investments decline in value and remain below cost for an extended duration, we may incur additional financial statement charges.

                        Government regulation imposes significant costs and restrictions on the development and commercialization of our products and services.

                                Our success will depend on our ability to satisfy regulatory requirements. We may not receive required regulatory approvals on a timely basis or at all. Government agencies heavily regulate the production and sale of healthcare products and the provision of healthcare services. In particular, the FDA and comparable regulatory agencies in foreign jurisdictions must approve human therapeutic and diagnostic products before they are marketed, as well as the facilities in which they are made. This approval process can involve lengthy and detailed laboratory and clinical testing, sampling activities and other costly and time-consuming procedures. Several biotechnology companies have failed to obtain regulatory approvals because regulatory agencies were not satisfied with the structure or conduct of clinical trials. Similar problems could delay or prevent us from obtaining approvals. Furthermore, regulatory authorities, including the FDA, may not agree with our interpretations of our clinical trial data, which could delay, limit or prevent regulatory approvals.

                                Therapies that have received regulatory approval for commercial sale may continue to face regulatory difficulties. If we fail to comply with applicable regulatory requirements, regulatory authorities could take actions against us, including:

                          issuing warning letters;

                          issuing fines and other civil penalties;

                          suspending regulatory approvals;


                            refusing to approve pending applications or supplements to approved applications;

                            suspending product sales, imports and/or exports;

                            requiring us to communicate with physicians and other customers about concerns related to potential safety, efficacy, and other issues involving Genzyme products;

                            mandating product recalls; and

                            seizing products.

                                  Furthermore, the FDA and comparable foreign regulatory agencies may require post-marketing clinical trials or patient outcome studies. We have agreed with the FDA, for example, to a number of post-marketing commitments as a condition to U.S. marketing approval for Fabrazyme, Aldurazyme and Myozyme.Myozyme and Clolar. In addition, regulatory agencies subject a marketed therapy, its manufacturer and the manufacturer's facilities to continual review and periodic inspections. The discovery of previously unknown problems with a therapy or the facility or process used to produce the therapy could prompt a regulatory authority to impose restrictions on us, or could cause us to voluntarily adopt such restrictions, including withdrawal of one or more of our products or services from the market. For example, we received a warning letter from the FDA onin September 19, 2007 that addresses certain of our manufacturing procedures in our Thymoglobulin production facility in Lyon, France. There is no current impactThe FDA has accepted our response to product supply as a result of the FDA warning letter and we are in ongoing discussions with the FDAcontinue to resolve the issues described in the letter.work to optimize our processes at this plant.

                          We may incur substantial costs as a result of litigation or other proceedings.

                                  A third party may sue us or one of our strategic collaborators for infringing the third party's patent or other intellectual property rights. Likewise, we or one of our strategic collaborators may sue to enforce intellectual property rights or to determine the scope and validity of third party proprietary rights. If we do not prevail in this type of litigation, we or our strategic collaborators may be required to:

                            pay monetary damages;


                              stop commercial activities relating to the affected products or services;

                              obtain a license in order to continue manufacturing or marketing the affected products or services; or

                              compete in the market with a different product.

                                    We are also currently involved in litigation matters and investigations that do not involve intellectual property claims and may be subject to additional actions in the future. For example, the federal government, state governments and private payors are investigating and have begun to file actions against numerous pharmaceutical and biotechnology companies, including Genzyme, alleging that the companies have overstated prices in order to inflate reimbursement rates. Domestic and international enforcement authorities also have instituted actions under healthcare "fraud and abuse" laws, including anti-kickback and false claims statutes. Moreover, individuals who use our products or services, including our diagnostic products and genetic testing services, sometimes bring product and professional liability claims against us or our subsidiaries.

                                    We may also become subject to investigations by government authorities in connection with our business activities. For example, we are currently cooperating with an investigation of Bone Care (a company we acquired in July 2005) by the United States Attorney for the Eastern District of New York which was initiated in October 2004, when Bone Care received a subpoena requiring it to provide a wide range of documents related to numerous aspects of its business.



                                    We believe some of our products are prescribed by physicians for uses not approved by the FDA or comparable regulatory agencies outside the United States. Although physicians may lawfully prescribe our products for off-label uses, any promotion by us of off-label uses would be unlawful. Some of our practices intended to make physicians aware of off-label uses of our products without engaging in off-label promotion could nonetheless be construed as off-label promotion. Although we have policies and procedures in place designed to help assure ongoing compliance with regulatory requirements regarding off-label promotion, some non-compliant actions may nonetheless occur. Regulatory authorities could take enforcement action against us if they believe we are promoting, or have promoted, our products for off-label use.

                                    We have only limited amounts of insurance, which may not provide coverage to offset a negative judgment or a settlement payment. We may be unable to obtain additional insurance in the future, or we may be unable to do so on acceptable terms. Our insurers may dispute our claims for coverage. For example, we have submitted claims to our insurers for reimbursement of portions of the expenses incurred in connection with the litigation and settlement related to the consolidation of our tracking stock and are seeking coverage for the settlement. The insurer has purported to deny coverage. Any additional insurance we do obtain may not provide adequate coverage against any asserted claims.

                                    Regardless of merit or eventual outcome, investigations and litigations can result in:

                              the diversion of management's time and attention;

                              the expenditure of large amounts of cash on legal fees, expenses, and payment of damages;

                              limitations on our ability to continue some of our operations;

                              decreased demand for our products and services; and

                              injury to our reputation.

                            Our international sales, clinical activities, manufacturing and other operations are subject to the economic, political, legal and business environments of the countries in which we do business, and our failure to operate successfully or adapt to changes in these environments could cause our international sales and operations to be limited or disrupted.

                                    Our international operations accounted for approximately 47%52% of our consolidated product and service revenues for the ninethree months ended September 30, 2007.March 31, 2008. We expect that international product and



                            service sales will continue to account for a significant percentage of our revenues for the foreseeable future. In addition, we have direct investments in a number of subsidiaries outside of the United States, primarily in the European Union, Latin America and Japan.States. Our international sales and operations could be limited or disrupted, and the value of our direct investments may be diminished, by any of the following:

                              economic problems that disrupt foreign healthcare payment systems;

                              the imposition of governmental controls;controls, including foreign exchange and currency restrictions;

                              less favorable intellectual property or other applicable laws;

                              the inability to obtain any necessary foreign regulatory or pricing approvals of products in a timely manner;

                              the inability to obtain third party reimbursement support for products;

                              product counterfeiting and intellectual property piracy;

                              parallel imports;

                              anti-competitive trade practices;


                                import and export license requirements;

                                political instability;

                                terrorist activities, armed conflict, or outbreak of diseases such as severe acute respiratory syndrome (SARS) or avian influenza;a pandemic;

                                restrictions on direct investments by foreign entities and trade restrictions;

                                changes in tax laws and tariffs;

                                difficulties in staffing and managing international operations; and

                                longer payment cycles.

                                      Our operations and marketing practices are also subject to regulation and scrutiny by the governments of the other countries in which we operate. In addition, the United States Foreign Corrupt Practices Act prohibits U.S. companies and their representatives from offering, promising, authorizing or making payments to foreign officials for the purpose of obtaining or retaining business abroad. Failure to comply with domestic or foreign laws could result in various adverse consequences, including possible delay in the approval or refusal to approve a product, recalls, seizures, withdrawal of an approved product from the market, and/or the imposition of civil or criminal sanctions.

                              Our international sales and operating expenses are subject to fluctuations in currency exchange rates.

                                      A significant portion of our business is conducted in currencies other than our reporting currency, the U.S. dollar. We recognize foreign currency gains or losses arising from our operations in the period in which we incur those gains or losses. As a result, currency fluctuations among the U.S. dollar and the currencies in which we do business have caused foreign currency translation gains and losses in the past and will likely do so in the future. Because of the number of currencies involved, the variability of currency exposures and the potential volatility of currency exchange rates, we may suffer significant foreign currency translation losses in the future due to the effect of exchange rate fluctuations.


                              We may fail to adequately protect our proprietary technology, which would allow competitors or others to take advantage of our research and development efforts.

                                      Our long-term success largely depends on our ability to market technologically competitive products. If we fail to obtain or maintain adequate intellectual property protection in the United States or abroad, we may not be able to prevent third parties from using our proprietary technologies. Our currently pending or future patent applications may not result in issued patents. Patent applications are confidential for 18 months following their filing, and because third parties may have filed patent applications for technology covered by our pending patent applications without us being aware of those applications, our patent applications may not have priority over patent applications of others. In addition, our issued patents may not contain claims sufficiently broad to protect us against third parties with similar technologies or products, or provide us with any competitive advantage. If a third party initiates litigation regarding our patents, our collaborators' patents, or those patents for which we have license rights, and is successful, a court could declare our patents invalid or unenforceable or limit the scope of coverage of those patents. Governmental patent offices and courts have not consistently treated the breadth of claims allowed in biotechnology patents. If patent offices or the courts begin to allow or interpret claims more broadly, the incidence and cost of patent interference proceedings and the risk of infringement litigation will likely increase. On the other hand, if patent offices or the courts begin to allow or interpret claims more narrowly, the value of our proprietary rights may be reduced. Any changes in, or unexpected interpretations of, the patent laws may adversely affect our ability to enforce our patent position.


                                      We also rely upon trade secrets, proprietary know-how, and continuing technological innovation to remain competitive. We attempt to protect this information with security measures, including the use of confidentiality agreements with employees, consultants, and corporate collaborators. These individuals may breach these agreements and any remedies available to us may be insufficient to compensate for our damages. Furthermore, our trade secrets, know-how and other technology may otherwise become known or be independently discovered by our competitors.

                              Some of our products may face competition from lower cost generic or follow-on products in the future.

                                      Some of our drug products, for example Renagel, Renvela, Clolar and Hectorol, are approved under the provisions of the United States Food, Drug and Cosmetic Act that render them susceptible to potential competition from generic manufacturers via the Abbreviated New Drug Application (ANDA) procedure. Generic manufacturers pursuing ANDA approval are not required to conduct costly and time-consuming clinical trials to establish the safety and efficacy of their products; rather, they are permitted to rely on the innovators data regarding safety and efficacy. Thus, generic manufacturers can sell their products at prices much lower than those charged by the innovative pharmaceutical companies who have incurred substantial expenses associated with the research and development of the drug product.

                                      The ANDA procedure includes provisions allowing generic manufacturers to challenge the effectiveness of the innovator's patent protection long prior to the generic manufacturer actually commercializing their products—the so-called "Paragraph IV" certification procedure. In recent years, generic manufacturers have used Paragraph IV certifications extensively to challenge patents on a wide array of innovative pharmaceuticals, and we expect this trend to continue and to implicate drug products with even relatively small total revenues.

                                      Other of our products, including Cerezyme, Fabrazyme, Aldurazyme, Myozyme and Campath (so-called "biotech drugs") are not currently considered susceptible to an abbreviated approval procedure, either due to current United States law or FDA practice in approving biologic products. However, the United States Congress is expected to continue to explore, and ultimately enact,



                              legislation that would establish a procedure for the FDA to accept ANDA-like abbreviated applications for the approval of "follow-on," "biosimilar" or "comparable" biotech drugs. Such legislation has already been adopted in the European Union.

                                      A generic manufacturer has filed an ANDA seeking to market a generic version of Hectorol prior to the expiration dates of our patents covering the product. If this or any other manufacturer were to receive approval to sell a generic or follow-on version of one of our products, that product would become subject to increased competition and our revenues for that product would likely be impacted negatively.

                              We may be required to license technology from competitors or others in order to develop and commercialize some of our products and services, and it is uncertain whether these licenses would be available.

                                      Third party patents may cover some of the products or services that we or our strategic partners are developing or producing. A patent is entitled to a presumption of validity and accordingly, we face significant hurdles in any challenge to a patent. In addition, even if we are successful in challenging the validity of a patent, the challenge itself may be expensive and require significant management attention.

                                      To the extent valid third party patent rights cover our products or services, we or our strategic collaborators would be required to seek licenses from the holders of these patents in order to manufacture, use or sell these products and services, and payments under them would reduce our profits from these products and services. We may not be able to obtain these licenses on acceptable terms, or at all. If we fail to obtain a required license or are unable to alter the design of our technology to fall outside the scope of a third party patent, we may be unable to market some of our products and services, which would limit our profitability.

                              Importation of products may lower the prices we receive for our products.

                                      In the United States and abroad, many of our products are subject to competition from lower-priced versions of our products and competing products from other countries where government price controls or other market dynamics result in lower prices for such products. Our products that require a prescription in the United States may be available to consumers in markets such as Canada, Mexico, Taiwan and the Middle East without a prescription, which may cause consumers to further seek out these products in these lower priced markets. The ability of patients and other customers to obtain these lower priced imports has grown significantly as a result of the Internet, an expansion of pharmacies in Canada and elsewhere that target American purchasers, thean increase in U.S.-based businesses affiliated with Canadian pharmacies marketing to American purchasers and other factors. Most of these foreign imports are illegal under current United States law. However, the volume of imports continues to rise due to the limited enforcement resources of the FDA and the United States Customs Service, and there is increased political pressure to permit such imports as a mechanism for expanding access to lower priced medicines. The importation of lower-priced versions of our products into the United States and other markets adversely affects our profitability. This impact could become more significant in the future.

                              Legislative or regulatory changes may adversely impact our business.

                                      The United States government and other governments have shown significant interest in pursuing healthcare reform. Any government-adopted reform measures could adversely impact:

                                the pricing of healthcare products in the United States or internationally; and

                                the amount of reimbursement available from governmental agencies or other third party payors.

                                        New laws, regulations and judicial decisions, or new interpretations of existing laws, regulations and decisions, that relate to healthcare availability, methods of delivery or payment for products and



                                services, or sales, marketing or pricing may cause our revenue to decline, and we may need to revise our research and development programs.

                                        On September 27, 2007, the Food and Drug Administration Amendments Act of 2007 (the "FDAAA") was enacted, giving the FDA enhanced post-market authority, including the authority to require post-marketpost-marketing studies and clinical trials, labeling changes based on new safety information, and compliance with risk evaluationevaluations and mitigation strategies approved by the FDA. The FDA's exercise of its new authority could result in delays or increased costs during the period of product development, clinical trials and regulatory review and approval, increased costs to assure compliance with new post-approval regulatory requirements, and potential restrictions on the sale of approved products.

                                If our strategic alliances are unsuccessful, our operating results will be negatively impacted.

                                        Several of our strategic initiatives involve alliances with other biotechnology and pharmaceutical companies. The success of these arrangements is largely dependent on technology and other intellectual property contributed by our strategic partners or the resources, efforts, and skills of our partners. Disputes and difficulties in such relationships are common, often due to conflicting priorities or conflicts of interest. Merger and acquisition activity may exacerbate these conflicts. The benefits of these alliances are reduced or eliminated when strategic partners:

                                  terminate the agreements or limit our access to the underlying intellectual property;

                                  fail to devote financial or other resources to the alliances and thereby hinder or delay development, manufacturing or commercialization activities;

                                  fail to successfully develop, manufacture or commercialize any products; or

                                  fail to maintain the financial resources necessary to continue financing their portion of the development, manufacturing, or commercialization costs of their own operations.

                                        Furthermore, payments we make under these arrangements may exacerbate fluctuations in our financial results. In addition, under some of our strategic alliances, we make milestone payments well in advance of commercialization of products with no assurance that we will ever recoup these payments. We also may make equity investments in our strategic partners, as we did with RenaMed Biologics, Inc., or RenaMed, in June 2005. Our strategic equity investments are subject to market fluctuations, access to capital and other business events, such as initial public offerings, the completion of clinical trials and regulatory approvals, which can impact the value of these investments. For example, in October 2006, RenaMed suspended clinical trials of its renal assist device which was being developed to treat patients with acute renal failure, causing us to write off our entire investment in RenaMed. If any of our other strategic equity investments decline in value and remain below cost for an extended duration, we may incur additional charges.

                                We may require significant additional financing, which may not be available to us on favorable terms, if at all.

                                        As of September 30, 2007,March 31, 2008, we had $1.4 billion in cash, cash equivalents and short- and long-term investments, excluding our investments in equity securities.

                                        We intend to use substantial portions of our available cash for:

                                  product development and marketing;

                                  payments related to the cash consideration for our merger withdue to the dissenting Bioenvision includingshareholders, the approximately $245 millionamount of cash we paid in October 2007 upon completionwhich will be determined by the Delaware Court of the merger, the approximately $11 million of cash we intend to pay in the fourth quarter of 2007 for the outstanding options to purchase shares of Bioenvision Common Stock;Chancery;


                                    other business combinations and strategic business initiatives, including the approximately $53 million in Canadian dollars, or approximately $57 million U.S. dollars (based on the November 2, 2007 spot rate for the Canadian dollar), of cash we intend to spend in December 2007 for our planned acquisition of the diagnostics division of DCL;initiatives;

                                    the remaining $1.2 billion approved for our $1.5 billionongoing stock repurchase program;program over approximately the next 2 years;

                                    upgrading our information technology systems;

                                    expanding existing and constructing additionalnew manufacturing facilities;

                                    contingent payments under license and other agreements, including payments related to our license of mipomersen from Isis;

                                    working capital and satisfaction of our obligations under capital and operating leases.

                                          We may further reduce available cash reserves to pay principal and interest on outstanding debt, including our $690.0 million in principal of 1.25% convertible senior notes.

                                          To satisfy our cash requirements, we may have to obtain additional financing. We may be unable to obtain any additional financing or extend any existing financing arrangements at all or on terms that we or our investors consider favorable.

                                  Our level of indebtedness may harm our financial condition and results of operations.

                                          As of September 30, 2007,March 31, 2008, we had $697.9$696.8 million of outstanding indebtedness, excluding capital leases. We may incur additional indebtedness in the future. Our level of indebtedness will have several important effects on our future operations, including:

                                    increasing our vulnerability to adverse changes in general economic and industry conditions; and

                                    limiting our ability to obtain additional financing for capital expenditures, acquisitions and general corporate and other purposes.

                                            Our ability to make payments and interest on our indebtedness depends upon our future operating results and financial performance.

                                    Market Risk

                                            We are exposed to potential loss from exposure to market risks represented principally by changes in foreign exchange rates, interest rates and equity prices. At September 30, 2007,March 31, 2008, we held derivative contracts in the form of foreign exchange forward contracts. We also held a number of other financial instruments, including investments in marketable securities and we had debt securities outstanding. We do not hold derivatives or other financial instruments for speculative purposes.

                                            As a result of our worldwide operations, we face exposure to potential adverse movementsWe hold investments in foreign currency exchange rates, primarily to the Euro, British pound and Japanese yen. Exposures to currency fluctuations that result from sales of our products in foreign markets are partially offset by the impact of currency fluctuations on our international expenses. We use forward foreign exchange contracts to further reduce our exposure to changes in exchange rates. We also hold a limited amountnumber of foreign cashU.S. and European equity securities.

                                    Interest Rate Risk

                                            We are exposed to potential loss due to changes in interest rates. Our principal interest rate exposure is to changes in U.S. interest rates. Instruments with interest rate risk include short- and long-term investments in fixed income securities. Other exposures to interest rate risk include the fair value of fixed rate convertible debt and other fixed rate debt. To estimate the potential loss due to changes in interest rates, we performed a sensitivity analysis using the instantaneous adverse change in interest rates of 100 basis points across the yield curve.

                                            We used the following assumptions in preparing the sensitivity analysis for our convertible notes:bonds:

                                      convertible notes that are "in-the-money" at September 30, 2007March 31, 2008 are considered equity securities and are excluded;

                                      convertible notes that are "out-of-the-money" at September 30, 2007March 31, 2008 are analyzed by taking into account both fixed income and equity components; and

                                      convertible notes will mature on the first available put or call date.

                                            On this basis, we estimate the potential loss in fair value that would result from a hypothetical 1% (100 basis points) decreaseincrease in interest rates to be $2.6$3.5 million as of September 30, 2007,March 31, 2008, as compared to $4.2$3.3 million as of December 31, 2006.2007.

                                      Legal Proceedings

                                            We periodically become subject to legal proceedings and claims arising in connection with our business.

                                            Through June 30, 2003, Although we had three outstanding series of common stock, which we referred to as tracking stocks; Genzyme General Stock (which we now refer to as Genzyme Stock), Biosurgery Stock and Molecular Oncology Stock. Four lawsuits were filed against us regarding the exchange of all of the outstanding shares of Biosurgery Stock for shares of Genzyme Stock in connection with the elimination of our tracking stocks in July 2003. Each of the lawsuits was a purported class action on behalf of holders of Biosurgery Stock. The first case, filed in the MSC in May 2003, alleged a breach of the implied covenant of good faith and fair dealing in our charter and a breach of our board of directors' fiduciary duties. The plaintiff in this case sought an injunction to adjust the exchange ratio for the tracking stock exchange. The MSC dismissed the complaint in its entirety in November 2003. Upon appeal, the Massachusetts Appeals Court upheld the dismissal by the MSC of the fiduciary duty claim, but reversed the earlier decision to dismiss the implied covenant claim. The Massachusetts Supreme Judicial Court (SJC) granted our petition for further appellate review. On June 4, 2007, the SJC reversed the Appeals Court's decision and affirmed dismissal of the complaint in its entirety. On July 25, 2007, the SJC denied the plaintiff's petition for rehearing. Two substantially similar cases were filed in the MSC in August and October 2003. These cases were consolidated in January 2004, and in July 2004, the consolidated case was stayed pending disposition of a fourth case, which was filed in the U.S. District Court for the Southern District of New York in June 2003. As amended, this complaint alleged violations of federal securities laws, as well as various state law claims, related to the exchange, on behalf of a certified class of holders of Biosurgery Stock as of May 8, 2003. On August 6, 2007, we reached an agreement-in-principle with counsel for the plaintiff class to settle and dismiss this case for approximately $64 million. A definitive settlement agreement was approved by the court on October 26, 2007. Because the members of the class in the New York action released all claims, the settlement has, as a practical matter, resolved the consolidated case in the MSC. We have submitted claims to our insurers for reimbursement of portions of the expenses incurred and to be incurred in connection with these cases; the insurer has purported to deny coverage. We intend to vigorously pursue our rights with respect to insurance coverage. As a result, we recorded a liability for the settlement payment of approximately $64 million as a charge to SG&A in our consolidated statements of operations in June 2007, which we subsequently paid in August 2007.

                                    In May 2007, our board of directors authorized a stock repurchase program to repurchase up to an aggregate maximum amount of $1.5 billion or 20,000,000 shares of our outstanding common stock over the next three years. The repurchases are being made from time to time and can be effectuated through open market purchases, privately negotiated transactions, transactions structured through investment banking institutions, or by other means, subject to management's discretion and as permitted by securities laws and other legal requirements. The manner of the purchase, the amount that we spend and the number of shares we ultimately purchase will vary based on a range of factors, including share price. The program does not obligate us to acquire any particular amount of common stock and the program may be suspended at any time at our discretion.
