 MANAGEMENT'S DISCUSSION AND ANALYSIS OF GENZYME GENERAL'S FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

INTRODUCTION

    This discussion contains forward-looking statements. These forward-looking
statements represent the expectations of our management as of the filing date of
this annual report. Actual results could differ materially from those
anticipated by the forward-looking statements due to the risks and uncertainties
described under the caption "Factors Affecting Future Operating Results" for
Genzyme General and Genzyme Corporation included in this annual report. You
should consider carefully each of these risks and uncertainties in evaluating
the financial condition and results of operations of Genzyme General and
Genzyme.

    In June 1999, we created Genzyme Surgical Products. The business of Genzyme
Surgical Products previously operated as a business unit of Genzyme General. The
discussion that follows reflects the results of operations of Genzyme General as
if Genzyme Surgical Products had existed as a separate division of Genzyme for
all periods presented.

    For purposes of financial presentation, we allocate certain of our programs,
products, assets and liabilities to Genzyme General and prepare separate
financial statements for Genzyme General. Notwithstanding the allocation of
assets and liabilities to Genzyme General, Genzyme Corporation continues to hold
title to all of the assets and is responsible for all of the liabilities
allocated to Genzyme General. Holders of GENZ Stock are common stockholders of
Genzyme Corporation and have no specific rights to the assets to which GENZ
Stock relates.

    We present financial information and accounting policies specific to Genzyme
General in the accompanying combined financial statements. We present financial
information and accounting policies relevant to the corporation and its
operating divisions taken as a whole in our consolidated financial statements.

    You should, therefore, read this discussion and analysis of Genzyme
General's financial position and results of operations in conjunction with the
financial statements and related notes of Genzyme General, the discussion and
analysis of Genzyme's financial position and results of operations, and the
consolidated financial statements and related notes of Genzyme, all of which are
included in this annual report.

                                      GG-5

are necessary for an understanding of Genzyme General's financial statements.

THERAPEUTICS

    Genzyme General's increase in product revenue during both periods is largely
due to increased sales of Cerezyme-Registered Trademark- enzyme, which was
attributed to the identification of new Gaucher disease patients throughout the
world and strong international sales. We have provided information regarding the
growth in sales of Genzyme General's Gaucher disease therapies during both
periods in the following table:



                                                                               99/98        98/97

    Genzyme General's results of operations are highly dependent on sales of
Cerezyme-Registered Trademark- enzyme and a reduction in revenue from sales of
this product would adversely affect its results of operations. Revenue from
Cerezyme-Registered Trademark- enzyme would be impacted negatively if
competitors developed alternative treatments for Gaucher disease and the
alternative products gained commercial acceptance. Genzyme General is aware of
companies that have initiated efforts to develop competitive products and other
companies may do so in the future.

    Therapeutics revenue for each period also includes sales of
Thyrogen-Registered Trademark- hormone, which is an adjunctive diagnostic tool
for well differentiated thyroid cancer.

DIAGNOSTIC PRODUCTS

    The decrease in diagnostic products revenue for 1999 as compared to 1998
reflects the sale of the research products business to Techne Corporation in
July 1998 and immunochemistry product line to an operating unit of Sybron
Laboratory Products Corp. in July 1999. Diagnostic products revenue includes
royalties on product sales by Techne's biotechnology group.

OTHER

    Other revenue for each period include sales of:

    - lipids and peptides for drug delivery; and

    - genetic testing services.

                                      GG-7

INTERNATIONAL PRODUCT AND SERVICE REVENUE

    A substantial portion of Genzyme General's revenue was generated outside of
the United States, as described in the following table. Most of these revenues
were attributable to sales of Cerezyme-Registered Trademark- enzyme.

    Genzyme General provides a broad range of healthcare products and services.
As a result, Genzyme General's gross margin varies significantly based on the
category of product or service. Sales of therapeutic products, including
Cerezyme-Registered Trademark- enzyme, result in higher margins than diagnostic
products.

    During 1998, Genzyme General recorded a $14.8 million charge to cost of
products sold to write down excess inventory used to make
Ceredase-Registered Trademark- enzyme. Without the effect of this charge,
Genzyme General's product margin for 1998 would have been 76% and its total
gross margin during that period would have been 72%.

    Excluding the charge described above, the increases in product margin and
total gross margin during each period are a result of increased efficiency and
process improvements in manufacturing as well as increased sales of
Cerezyme-Registered Trademark- enzyme.

    Our service margin also increased during each period as a result of
increases in sales of DNA and cancer testing services.

OPERATING EXPENSES

1999 AS COMPARED TO 1998

    The increase in selling, general and administrative expenses in 1999 as
compared to 1998 is related to:

    - increased staffing to support the growth in several of Genzyme General's
      product lines;

    - an increased reserve for doubtful accounts in Genzyme General's genetic
      testing business;

    - costs associated with the market introduction of
      Thyrogen-Registered Trademark- hormone in January 1999; and

                                      GG-8

    - increased expenditures to support the increased sales of
      Cerezyme-Registered Trademark- enzyme.

    The increase in research and development expense in 1999 as compared to 1998
is a result of:

    - increased costs in connection with the results of ATIII LLC, the joint
      venture with Genzyme Transgenics Corporation for the development and
      commercialization of transgenic recombinant human antithrombin III; and

    - increased spending on Genzyme General's program to develop Fabrazyme-TM-
      enzyme for the treatment of Fabry disease and other internal programs.

    In the fourth quarter of 1998, Genzyme General began amortizing a milestone
payment that it made to GelTex Pharmaceuticals, Inc. upon FDA approval of
RenaGel-Registered Trademark- capsules. As a result, amortization of intangibles
increased slightly during 1999 as compared to 1998.

    In 1999, we acquired Peptimmune, Inc., a privately-held company whose lead
development program focuses on a treatment for pemphigus vulgaris. We allocated
$5.4 million to in-process technology representing Peptimmune's programs that
were still in the development stage and for which there was no alternative
future use. In 1999, we recorded a one-time charge to operations for the amount
of the purchase price allocated to in-process technology.

1998 AS COMPARED TO 1997

    The increase in selling, general and administrative expenses in 1998 as
compared to 1997 was related to:

    - increased sales and marketing costs related to the product launch of
      Thyrogen-Registered Trademark- hormone; and

    - increased expenditures to support the increased sales of
      Cerezyme-Registered Trademark- enzyme.

    The increase in research and development expense in 1998 as compared to 1997
was primarily attributable to $12.0 million in costs resulting from the
consolidation of the results of ATIII LLC, for which there were no comparable
amounts in 1997.

1999 AS COMPARED TO 1998

EQUITY IN NET LOSS OF UNCONSOLIDATED AFFILIATES

    Genzyme General records in equity in net loss of unconsolidated affiliates
its portion of the results of its joint ventures with GelTex, BioMarin
Pharmaceutical Inc., Pharming Group, N.V. and Diacrin, Inc. Genzyme General also
records a portion of the results of Genzyme Transgenics in equity in net loss of
unconsolidated affiliates.

    Genzyme General's equity in net loss of unconsolidated affiliates increased
in 1999 as compared to 1998 as a result of:

    - increased losses from RenaGel LLC, our joint venture with GelTex to
      develop and commercialize Renagel-Registered Trademark- capsules;

    - increased losses from our joint venture with BioMarin to develop and
      commercialize Aldurazyme(TM) enzyme for the treatment of
      mucopolysaccharidosis-I, which was formed in September 1998;

    - increased losses from our joint venture with Pharming to develop a therapy
      for Pompe disease, which was formed in October 1998; and

    - the reallocation of our joint venture with Diacrin from Genzyme Tissue
      Repair to Genzyme General in May 1999.

    These increases were offset in part by decreased losses from Genzyme
Transgenics for both periods.

GAIN ON AFFILIATE SALE OF STOCK

    In 1999 and 1998, Genzyme General recorded gains on its investment in
Genzyme Transgenics as a result of its issuance of additional shares of common
stock.

MINORITY INTEREST

    Genzyme General consolidates the results of ATIII LLC and records Genzyme
Transgenics' portion of the losses of that joint venture as minority interest.
Minority interest decreased in both periods, notwithstanding increases in ATIII
LLC's losses, because Genzyme Transgenics' portion of those losses decreased.

GAIN ON SALE OF INVESTMENTS IN EQUITY SECURITIES

    Genzyme General recorded gains of $2.0 million in January 1999 and
$3.4 million in December 1998 upon the sales of shares of Techne common stock
that it received when it sold its research products business to Techne.

GAIN ON SALE OF PRODUCT LINE

    In July 1999, Genzyme General recorded a gain of $0.5 million in connection
with the sale of its immunochemistry product lines to an operating unit of
Sybron Laboratory Products.

    In June 1999, Genzyme General recorded a gain of $7.5 million representing
the payment of a note receivable that it received as partial consideration for
the sale of Genetic Design, Inc. in 1996. Genzyme General had previously fully
reserved the amount of this note because it considered the repayment of the note
to be uncertain.

    In July 1998, Genzyme General recorded a gain of $31.2 million in connection
with the sale of its research products business to Techne.

                                     GG-10

CHARGE FOR IMPAIRED INVESTMENTS

    In 1999, Genzyme General recorded $5.7 million in charges to write down
certain strategic investments in collaborators' common stock because it
considered the decline in the value of these investments to be other than
temporary.

    In 1998, Genzyme General recorded a $3.4 million charge to write down a
strategic investment in a company because we considered the decline in the value
of the company's common stock to be other than temporary.

OTHER

    In December 1999, Genzyme General recorded a net gain of $14.4 million upon
receipt of a payment associated with the termination of an agreement to acquire
Cell Genesys, Inc.

INVESTMENT INCOME

    Investment income increased in both periods because our cash balances were
higher. The increase in cash balances was attributable to the issuance in May
1998 of $250.0 million in principal amount of 5 1/4% convertible subordinated
notes and increased cash generated from operations.

INTEREST EXPENSE

    Genzyme General's interest expense increased in both periods, primarily as a
result of the issuance of the 5 1/4% convertible subordinated notes.

    - use of a foreign sales corporation;

    - nondeductible amortization of intangibles;

    - use of tax credits; and

    - share of losses of unconsolidated affiliates.

LIQUIDITY AND CAPITAL RESOURCES

    At December 31, 1999, Genzyme General had cash, cash-equivalents, and short-
and long-term investments of $513.9 million, a decrease of $42.2 million from
December 31, 1998.

    Genzyme General generated $284.8 million in cash from its operations in
1999.

    Genzyme General's investing activities utilized $192.7 million in cash in
1999. Investing activities generated:

    - $5.0 million from the sale of Genzyme General's immunochemistry product
      line;

    - $11.1 million from the sale of Techne common stock; and

    - $8.4 million from the payment of a note issued in connection with the sale
      of Genetic Design.

Investing activities used:

    - $93.4 million for Genzyme General's net purchases of investments;

    - $52.9 million to fund capital expenditures;

    - $36.4 million to fund Genzyme General's investments in joint ventures;

    - $6.5 million to fund its acquisition of Peptimmune;

    - $10.0 million to GelTex to make a milestone payment upon the first
      anniversary of FDA approval of Renagel-Registered Trademark- capsules;

    - $6.6 million to Genzyme Transgenics for the purchase of preferred stock;

    - $10.0 million to Biomarin for the purchase of shares of common stock; and

    - $3.4 million to Genovo, Inc. for the purchase of shares of preferred
      stock.

    In 1999, Genzyme General received $59.2 million in cash from employee stock
plans. Genzyme General's financing activities used the following cash during
1999:

    - $85.0 million to repay short-term debt and capital lease obligations; and

    - $49.4 million paid to Genzyme Surgical Products in connection with the
      creation of Genzyme Surgical Products as a separate division of Genzyme.

    - $30.0 million paid to Genzyme Tissue Repair for the transfer of the
      interest in Diacrin/Genzyme LLC and a draw under Genzyme Tissue Repair's
      equity line of credit.

    In 1998, our board of directors made $30.0 million of Genzyme General's cash
available to Genzyme Molecular Oncology under an equity line of credit. Under
the terms of this equity line, Genzyme Molecular Oncology may draw down funds as
needed each quarter in exchange for GZMO designated shares. GZMO designated
shares are shares of GZMO Stock that are not issued and outstanding, but which
our board of directors may issue, sell or distribute without allocating the
proceeds to Genzyme Molecular Oncology. Genzyme Molecular Oncology has not yet
drawn any funds under this equity line.

                                     GG-12

    In 1998, our board of directors also made $50.0 million of Genzyme General's
cash available to Genzyme Tissue Repair under an equity line of credit. Under
the terms of this equity line, Genzyme Tissue Repair may draw down funds as
needed each quarter in exchange for GZTR designated shares. GZTR designated
shares are shares of GZTR Stock that are not issued and outstanding, but which
our board of directors may issue, sell or distribute without allocating the
proceeds to Genzyme Tissue Repair. In February 1999, Genzyme Tissue Repair made
a $5.0 million draw under this equity line in exchange for 1,633,399 GZTR
designated shares. In May 1999, the amount available under this equity line was
reduced by $25.0 million in connection with the reallocation of our ownership
interest in Diacrin/Genzyme LLC from Genzyme Tissue Repair to Genzyme General.

    In June 1999, Genzyme General transferred $150.0 million in cash, cash
equivalents and investments to Genzyme Surgical Products in connection with the
creation of Genzyme Surgical Products as a separate division of Genzyme. In
exchange for this transfer, approximately 14.8 million shares of GZSP Stock were
issued and distributed as a dividend to holders of GENZ Stock.

    Genzyme General, together with our other operating divisions, has access to
Genzyme's revolving credit facilities. At December 31, 1999, $50.0 million was
available under a facility that matures in November 2000 and $77.0 million was
available under a facility that matures in November 2002.

    We believe that Genzyme General's available cash, investments and cash flow
from operations will be sufficient to fund its planned operations and capital
requirements for the foreseeable future. Although Genzyme General currently has
substantial cash resources and positive cash flow, it intends to use substantial
portions of its available cash for:

    - product development and marketing;

    - expanding facilities;

    - working capital; and

    - strategic business initiatives.

    Genzyme General's cash reserves will be further reduced to pay principal and
interest on the following debt:

    - $21.2 million in principal under our 5% convertible subordinated
      debentures due August 2003, which are convertible into GENZ Stock; and

    - $250.0 million in principal under our 5 1/4% convertible subordinated
      notes due June 2005, which are convertible into GENZ Stock.

    If Genzyme General uses cash to pay or redeem this debt, including the
interest due on it, its cash reserves will be diminished. In addition, Genzyme
General's cash resources will be reduced to the extent that the liabilities of
Genzyme Molecular Oncology, Genzyme Surgical Products or Genzyme Tissue Repair
affect our consolidated results of operations.

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

NEW ACCOUNTING PRONOUNCEMENTS, EURO, YEAR 2000 AND MARKET RISK

    See "Management's Discussion and Analysis of Genzyme Corporation and
Subsidiaries' Financial Condition and Results of Operations" included in this
annual report.

                                     GG-13

FACTORS AFFECTING FUTURE OPERATING RESULTS

    The future operating results of Genzyme General could differ materially from
the results described above due to the risks and uncertainties described below
and under the heading "Management's Discussion and Analysis of Genzyme
Corporation and Subsidiaries' Financial Condition and Results of
Operations--Factors Affecting Future Operating Results" included in this annual
report.

A REDUCTION IN REVENUES FROM SALES OF PRODUCTS THAT TREAT GAUCHER DISEASE WOULD
  HAVE AN ADVERSE EFFECT ON GENZYME GENERAL'S BUSINESS.

    Genzyme General generates a majority of its product revenues from sales of
Ceredase-Registered Trademark- enzyme and Cerezyme-Registered Trademark- enzyme,
which are products for patients with Gaucher disease. Sales of
Ceredase-Registered Trademark- enzyme and Cerezyme-Registered Trademark- enzyme
totaled $478.5 million for the year ended December 31, 1999, representing
approximately 84% of Genzyme General's product revenues for that year.

    Because Genzyme General's business is highly dependent on
Cerezyme-Registered Trademark- enzyme, a reduction in revenue from sales of this
product would have an adverse effect on its operations and may cause the value
of GENZ Stock to decline substantially. Revenues from
Cerezyme-Registered Trademark- enzyme would be impacted negatively if
competitors develop alternative treatments for Gaucher disease and these
alternative products gained commercial acceptance. Some companies have initiated
efforts to develop competitive products, and other companies may do so in the
future. Cerezyme-Registered Trademark- enzyme has orphan drug status, providing
it with market exclusivity in the U.S. until May 2001. We also have patents
protecting its manufacturing method until 2010 and its composition until 2013.
We cannot predict the effect that the expiration of orphan drug status and
market exclusivity will have on sales of Cerezyme-Registered Trademark- enzyme
after May 2001.

GENZYME GENERAL MAY NOT BE ABLE TO SUCCESSFULLY COMMERCIALIZE
  THYROGEN-REGISTERED TRADEMARK- HORMONE AND RENAGEL-REGISTERED TRADEMARK-
  CAPSULES.

    In January 1999, Genzyme General, together with Knoll Pharmaceutical
Company, launched U.S. sales of Thyrogen-Registered Trademark- recombinant
thyroid stimulating hormone for use in the treatment of thyroid cancer. At about
the same time, Genzyme General, in collaboration with GelTex
Pharmaceuticals, Inc., launched Renagel-Registered Trademark- capsules, a
non-absorbed phosphate binder used in the treatment of end-stage renal disease.
The commercial success of Thyrogen-Registered Trademark- hormone and
Renagel-Registered Trademark- capsules will depend on a number of factors,
including:

    - regulation by the FDA;

    - the ability to obtain regulatory approvals in foreign countries;

    - the development and commercial success of competitive products; and

    - the availability of third party reimbursement.

    Genzyme General cannot be sure that market penetration of
Thyrogen-Registered Trademark- hormone and Renagel-Registered Trademark-
capsules will increase.

IF THE STRATEGIC COLLABORATIONS GENZYME GENERAL HAS ENTERED INTO TO DEVELOP AND
  COMMERCIALIZE ITS PRODUCTS ARE NOT SUCCESSFUL, GENZYME GENERAL'S RESULTS OF
  OPERATIONS WILL BE ADVERSELY IMPACTED.

    Several of Genzyme General's strategic initiatives involve collaborations
with other biotechnology companies and arrangements with academic medical
centers. These include:

    - a joint venture with GelTex for the commercialization of
      Renagel-Registered Trademark- capsules;

                                     GG-14

    - an agreement with Knoll Pharmaceutical Company for the marketing of
      Thyrogen-Registered Trademark- hormone in the U.S.;

    - an agreement with Biogen, Inc. for the marketing of
      AVONEX-Registered Trademark- (Interferon-beta 1a), Biogen's treatment for
      relapsing forms of multiple sclerosis, in Japan following regulatory
      approval;

    - a joint venture with BioMarin for the development and commercialization of
      Aldurazyme(TM) enzyme for the treatment of the lysosomal storage known as
      mucopolysaccharidosis I;

    - a joint venture with Genzyme Transgenics for the development and
      commercialization of transgenic antithrombin III, a human protein that
      Genzyme Transgenics produces in the milk of genetically modified animals;

    - a joint venture with Pharming for the development and commercialization of
      human alpha-glucosidase for the treatment of Pompe disease;

    - an agreement with Genovo for the development of gene therapy products for
      the treatment of lysosomal storage disorders;

    - a relationship with Mount Sinai Medical Center for the development of a
      therapy for the treatment of Niemann-Pick disease;

    - a joint venture with Diacrin to develop and commercialize products and
      processes using porcine fetal cells for the treatment of Parkinson's
      disease and Huntington's disease; and

    - an agreement with Dyax Corp. to develop and commercialize the protein
      EPI-KAL2 for the treatment of chronic inflammatory diseases.

    Genzyme General plans to enter into additional collaborations in the future.
The success of these arrangements are largely dependent on the efforts and
skills of Genzyme General's collaborators. Genzyme General cannot guarantee
that:

    - these agreements will not be terminated;

    - its strategic collaborators will devote significant resources to the
      collaborations; or

    - any of these collaborations will result in the successful development or
      commercialization of any products.

OUR OPTION TO PURCHASE LIMITED PARTNERSHIP INTERESTS COULD DILUTE THE RIGHTS OF
HOLDERS OF GENZ STOCK.

    We organized Genzyme Development Partners, L.P., a special purpose research
and development entity, in 1989 and transferred to it technology and commercial
rights to our hyaluronic acid-based products designed to prevent the occurrence
and severity of post-operative adhesions. These products, which we refer to as
the Sepra products, are now allocated to Genzyme Surgical Products. We have an
option to purchase the limited partnership interests in the partnership. If this
option is exercised, we may have to issue shares of GENZ Stock or make
substantial cash payments or both. If we make payments in GENZ Stock, the rights
of holders of GENZ Stock could be diluted and the market price of that stock may
fall. If we make cash payments, our cash resources would diminish.

SUBSEQUENT EVENT

    In February 2000, we converted our shares of the Series B Convertible
Preferred Stock of Genzyme Transgenics into 1,048,021 shares of Genzyme
Transgenics common stock. Also in February 2000, Genzyme Transgenics completed a
public offering of its common stock. Genzyme General will recognize a gain on
affiliate sale of stock of approximately $20 million in the first quarter of
2000.

                     NOTES TO COMBINED FINANCIAL STATEMENTS

NOTE A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BUSINESS

    Genzyme General is our operating division that develops and markets:

    - therapeutic products, with an expanding focus on products to treat
      patients suffering from lysosomal storage disorders and other specialty
      therapeutics;

    - diagnostic products, with a focus on IN VITRO diagnostics; and

    - other products and services, such as genetic testing and lipids and
      peptides for drug delivery.

    Genzyme General Division Common Stock, which we refer to as "GENZ Stock," is
intended to reflect the value and track the performance of Genzyme General.

BASIS OF PRESENTATION; PRINCIPLES OF COMBINATION

    The combined financial statements of Genzyme General for each period include
the balance sheets, results of operations and cash flows of the businesses we
allocate to Genzyme General. We also allocate a portion of our corporate
operations to Genzyme General using methods we believe are reasonable. These
combined financial statements are prepared using amounts included in our
consolidated financial statements included in this annual report. We have
reclassified certain 1998 and 1997 data to conform with the 1999 presentation.

    In June 1999, we created Genzyme Surgical Products. Genzyme General
transferred $150.0 million in cash, cash equivalents and investments, and
certain other assets, to Genzyme Surgical Products in connection with the
creation of Genzyme Surgical Products as a separate division of Genzyme. The
business of Genzyme Surgical Products previously operated as a business unit of
Genzyme General. These financial statements reflect the financial position,
results of operations and cash flows of Genzyme General as if Genzyme Surgical
Products had existed as a separate division of the corporation for all periods
presented.

    We use the equity method to account for investments in entities in which
Genzyme General has a substantial ownership interest (20% to 50%), or in which
it participates in policy decisions. Genzyme General's consolidated net income
includes its share of the earnings of these entities. We report at fair value
investments in entities in which Genzyme General's ownership interest is less
than 20%.

FINANCIAL INFORMATION

    For purposes of financial presentation, we allocate certain of our programs,
products, assets and liabilities to Genzyme General and prepare separate
financial statements for Genzyme General. Notwithstanding the allocation of
assets and liabilities to Genzyme General, Genzyme Corporation continues to hold
title to all of the assets and is responsible for all of the liabilities
allocated to Genzyme General. Holders of GENZ Stock are common stockholders of
Genzyme Corporation and have no specific rights to the assets to which GENZ
Stock relates.

    We prepare the financial statements of Genzyme General in accordance with
generally accepted accounting principles, our management and accounting policies
and the divisional accounting policies approved by our board. We present
financial information and accounting policies specific to Genzyme General in the
accompanying combined financial statements. We present financial information and

                                     GG-20

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

NOTE A. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
accounting policies relevant to the corporation and its operating divisions
taken as a whole in our consolidated financial statements. You should read these
consolidated financial statements.

    Note A., "Summary of Significant Accounting Policies," to our consolidated
financial statements contains our accounting policies. We incorporate that
information into this note by reference.

DIVIDEND POLICY

    We have never paid a cash dividend on shares of GENZ Stock. We currently
intend to retain our earnings to finance future growth and do not anticipate
paying any cash dividends on GENZ Stock in the foreseeable future.

TRANSLATION OF FOREIGN CURRENCIES

    We translate the financial statements of foreign subsidiaries allocated to
Genzyme General from local currency into U.S. dollars and include translation
adjustments for these subsidiaries in division equity. Genzyme General's
division equity includes cumulative foreign currency translation charges of
$19.7 million at December 31, 1999 and $4.8 million at December 31, 1998.

    We include exchange gains and losses on intercompany balances which are
long-term in nature in our division equity. Our gains and losses on all other
transactions are included in our results of operations. Genzyme General recorded
a net gain of $0.6 million in 1999, a net gain of $0.3 million in 1998 and a net
loss of $0.1 million in 1997.

REVENUE RECOGNITION

    Genzyme General recognizes revenue from product sales when it ships the
product and title has passed, net of any applicable third party contractual
allowances and rebates. Genzyme General recognizes revenue from service sales
when it has finished providing the service or when it has achieved an applicable
milestone. Genzyme General recognizes revenue from research and development
contracts over the term of the applicable contract and as it incurs costs
related to that contract. Up front license fees, milestone fees and royalty
revenue are recognized as revenue only if there are no remaining performance
obligations and the fees are non-refundable.

NET INCOME (LOSS) PER SHARE

    To calculate basic earnings per share for Genzyme General, we divide the
earnings attributable to Genzyme General by the weighted average number of
outstanding shares of GENZ Stock during the applicable period. When we calculate
diluted earnings per share, we also include in the denominator all potentially
dilutive securities outstanding during the applicable period. To determine what
earnings are attributable to Genzyme General, we take its net income or loss for
the applicable period (determined in accordance with generally accepted
accounting principles) and adjust it for the tax benefits allocated to Genzyme
General in accordance with our management and accounting policies.

NOTE B. POLICIES GOVERNING THE RELATIONSHIP OF GENZYME'S OPERATING DIVISIONS

    Because each of our operating divisions is a part of a single company, our
board of directors has adopted policies to address issues that may arise among
divisions and to govern the management of and the relationships between each
division. With some exceptions that are mentioned specifically in this note, our
board may modify or rescind these policies, or adopt additional policies, in its
sole discretion without stockholder approval, subject only to our board's
fiduciary duty to stockholders. Generally accepted accounting principles require
that any change in policy be preferable (in accordance with these principles) to
the previous policy.

INTERDIVISION ASSET TRANSFERS

    Our board may at any time reallocate any program, product or other asset
from one division to any other division. We make reallocations at fair market
value, as determined by our board. In determining the fair market value of a
program under development, our board takes into account the following criteria:

    - the commercial potential of the program;

    - the phase of clinical development of the program;

    - the expenses associated with realizing any income from the program and the
      likelihood and time of the realization; and

    - other matters that our board and its financial advisors, if any, deem
      relevant.

    One division may pay another division the consideration for a reallocation
in cash or other consideration with a value equal to the fair market value of
the reallocated assets. In the case of a reallocation of assets from Genzyme
General to another division, our board may elect instead to account for the
reallocation as an increase in the designated shares representing the division
to which the assets are reallocated in accordance with the provisions of our
charter.

    Our policy regarding transfers of assets between divisions may not be
changed by our board without the approval of the holders of GENZ Stock voting as
a separate class unless the policy change does not affect Genzyme General.

OTHER INTERDIVISION TRANSACTIONS

    Our divisions may engage in transactions directly with one or more other
divisions or jointly with one or more other divisions and one or more third
parties. These transactions may include agreements by one division to provide
products and services for use by another division, license agreements and joint
ventures or other collaborative arrangements involving more than one division to
develop new products and services jointly and with third parties. These
transactions are subject to the following conditions:

    - We charge research and development (including clinical and regulatory
      support), distribution, sales, marketing, and general and administrative
      services (including allocated space) performed by one division for another
      division to the division for which the services are performed on a cost
      basis. We charge direct costs to the division for which we incur them. We
      allocate direct labor and indirect costs in reasonable and consistent
      manners based on the use by a division of relevant services. Divisions
      performing services for other divisions do not recognize revenue for the
      services they perform.

    - We charge the manufacturing of goods and performance of services by one
      division exclusively for another division to the division for which it is
      performed on a cost basis. We include in manufacturing costs an interest
      charge (based on our short-term borrowing rate at the beginning of the
      fiscal year) on the gross fixed assets used in the manufacturing process.
      We determine gross fixed assets for the facility used at the beginning of
      each fiscal year. We allocate direct labor and indirect costs in
      reasonable and consistent manners based on the benefit received by a
      division of related goods and services. Divisions performing services for
      other divisions do not recognize revenue for the services they perform.

    - Other than transactions involving research and development, manufacturing,
      distribution, sales, marketing, general and administrative services, which
      are addressed above, all interdivisional transactions are performed on
      terms and conditions obtainable in arm's length transactions with third
      parties. Divisions performing services for other divisions do not
      recognize revenue for the services they perform.

    - Our board must approve interdivisional transactions that are performed on
      terms and conditions other than as described above and are material to one
      or more of the participating divisions. In giving its approval, our board
      must determine that the transaction is fair and reasonable to each
      participating division and to holders of the common stock representing
      each participating division.

    - Divisions may make loans to other divisions. Any loan of $1 million or
      less matures within 18 months and accrues interest at the best borrowing
      rate available to the corporation for a loan of like type and duration.
      Our board must approve any loan in excess of $1 million. In giving its
      approval, our board must determine that the material terms of the loan,
      including the interest rate and maturity date, are fair and reasonable to
      each participating division and to holders of the common stock
      representing each such division.

    - All material interdivisional transactions are set forth in a written
      agreement that is signed by an authorized member of the management team of
      each division involved in the transaction.

TAX ALLOCATIONS

    We file a consolidated return and allocate income taxes to each division
based upon the financial statement income, taxable income, credits and other
amounts properly allocable to each division under generally accepted accounting
principles as if it were a separate taxpayer. We assess the realizability of our
deferred tax assets at the division level. As a result, our consolidated tax
provision may not equal the sum of the divisions' tax provision. As of the end
of any fiscal quarter, however, if a division cannot use any projected annual
tax benefit attributable to it to offset or reduce its current or deferred
income tax expense, we may allocate the tax benefit to the other divisions in
proportion to their taxable income without any compensating payment or
allocation.

ACCESS TO TECHNOLOGY AND KNOW-HOW

    Genzyme General has unrestricted access to all technology and know-how owned
or controlled by Genzyme Corporation that may be useful in its business, subject
to any obligations or limitations that apply to the corporation generally.

NOTE C. OTHER GAINS AND CHARGES

    In December 1999, Genzyme General recorded a net gain of $14.4 million upon
receipt of a payment associated with the termination of an agreement to acquire
Cell Genesys, Inc. Genzyme General recorded this gain as other income.

    During the third quarter of 1998, Genzyme General recorded a $14.8 million
charge to cost of products sold to write down excess inventory used to make
Ceredase-Registered Trademark- enzyme. Genzyme General took this charge
following a determination that, based on the status of efforts to convert
Gaucher disease patients to a treatment regimen using
Cerezyme-Registered Trademark- enzyme, the existing supply of
Ceredase-Registered Trademark- enzyme was sufficient to meet estimated patient
needs.

    Genzyme General also recorded $20.1 million in other charges in the fourth
quarter of 1997. The components of these charges are:

    - a $18.1 million charge to cost of products sold to write down excess
      inventory in Genzyme General's melatonin, bulk pharmaceuticals and fine
      chemical product lines. Genzyme General took this charge after it
      discontinued these product lines; and

    - a $2.0 million charge to other expense relating to uncertainty in
      collecting a note receivable that was issued upon the sale of Genetic
      Design, Inc.

NOTE D. DISPOSITIONS OF ASSETS

    In July 1998, we sold the assets of our research products business to Techne
Corporation in exchange for:

    - $24.8 million in cash;

    - approximately 987,000 shares of Techne common stock; and

    - royalties on product sales by Techne's biotechnology group through
      June 2003.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

NOTE D. DISPOSITIONS OF ASSETS (CONTINUED)
    We will record royalty income as it is earned. In 1998, we recorded a
$31.2 million gain in connection with the sale of this business and an
additional $3.4 million gain upon the sale of a portion of our investment in
Techne common stock. In 1999, we recorded a gain of $2.0 million upon the sale
of our remaining shares of Techne common stock. The $3.4 million and
$2.0 million gains were recorded as gains on sale of investments in equity
securities. The research products business had been allocated to Genzyme
General.

    Note C., "Dispositions of Assets," to our consolidated financial statements
contains information regarding:

       - the sale of Genzyme General's immunochemistry product lines to an
         operating unit of Sybron Laboratory Products Corp.; and

       - the sale of Genetic Design to Laboratory Corporation of America.

We incorporate that information into this note by reference.

NOTE E. PEPTIMMUNE ACQUISITION

    In July 1999, we acquired Peptimmune, Inc., a privately-held company whose
lead development program focuses on a treatment for pemphigus vulgaris. We
allocated this acquisition to Genzyme General and accounted for it as a
purchase. We allocated the aggregate purchase price of $6.5 million and assumed
liabilities of $0.3 million to the tangible and intangible assets we acquired
from Peptimmune based on their respective fair values (amounts in thousands):


                                                           
Property, plant & equipment.................................   $  128
Deferred tax asset..........................................    1,229
In-process technology.......................................    5,436
                                                               ------
    Total...................................................   $6,793
                                                               ======


    The $5.4 million allocated to in-process technology represents the value we
assigned to Peptimmune's programs that were still in the development stage and
for which there was no alternative future use. Genzyme General recorded this
amount as a charge to operations.

NOTE F. OFF-BALANCE SHEET FINANCIAL INSTRUMENTS

    Note E., "Off-Balance Sheet Financial Instruments," to our consolidated
financial statements contains information regarding interest rate swap contracts
that are allocated to Genzyme General. We incorporate that information into this
note by reference.

NOTE G. ACCOUNTS RECEIVABLE AND INTANGIBLE ASSETS

    Genzyme General's trade receivables primarily represent amounts due from
distributors, healthcare service providers and companies and institutions
engaged in research, development or production of pharmaceutical and
biopharmaceutical products. Genzyme General performs credit evaluations of its
customers on an ongoing basis and generally does not require collateral. Genzyme
General states accounts receivable at fair value after reflecting an allowance
for doubtful accounts. This allowance was $17.6 million at December 31, 1999 and
$9.9 million at December 31, 1998.

    Genzyme General's net intangible assets include $41.5 million in goodwill as
of December 31, 1999 and $48.5 million in goodwill as of December 31, 1998. This
goodwill is primarily a result of acquisitions.

    Genzyme General's accumulated amortization of intangible assets was
$38.5 million as of December 31, 1999 and $39.6 million as of December 31, 1998.

(1) Designated shares are shares of our common stock that are not issued and
    outstanding, but which our board of directors may issue, sell or distribute
    without allocating the proceeds to the division tracked by that series of
    stock. As of December 31, 1999, there were 1,688,237 GZMO designated shares,
    1,164,839 GZSP designated shares and 2,238,053 GZTR designated shares. The
    number of GZMO designated shares assumes that Genzyme Molecular Oncology
    does not complete a public offering of GZMO Stock prior to June 18, 2000. If
    such an offering is completed prior to that date, the number of GZMO
    designated shares reserved for issuance in connection with a draw under an
    equity line of credit in 1998 will decrease based on a formula set forth in
    our charter.

STOCK COMPENSATION PLANS

    We apply APB Opinion 25 and related interpretations in accounting for our
five stock-based compensation plans: the 1990 Equity Incentive Plan, the 1997
Equity Plan (both of which are stock option plans), the 1990 Employee Stock
Purchase Plan, the 1999 Employee Stock Purchase Plan, and the 1998 Director
Stock Option Plan. Genzyme General does not recognize compensation expense for
options granted and shares purchased under the provisions of these plans for
options granted to employees with an exercise price greater than or equal to
fair market value.

    As a result of uncertainty surrounding our ability to realize certain tax
benefits that primarily relate to capital losses from the purchase of in-process
research and development, we placed valuation

                                     GG-35

NOTE P. INCOME TAXES (CONTINUED)
allowances of $17.6 million in 1999 and $15.4 million in 1998 against otherwise
recognizable deferred tax assets.

    Our ability to realize the benefit of net deferred tax assets is dependent
on our generating sufficient taxable income before loss carryforwards expire.
While it is not assured, we believe that it is more likely than not that we will
be able to realize all of our net deferred tax assets. The amount we can
realize, however, could be reduced in the near term if estimates of future
taxable income during the carryforward period are reduced.

    At December 31, 1999, Genzyme General had for U.S. income tax purposes a net
operating loss carryforwards of $9.0 million and a tax credit carryforward of
$9.4 million. The net operating loss carryforwards expire between 2003 and 2019
and, prior to expiration, Genzyme General's ability to use this carryforward may
be limited under U.S. tax laws. Tax credits of $4.9 million will carryforward
indefinitely and approximately $4.5 million of the tax credit carryforwards will
expire from 2014 to 2019. Approximately $9.4 million of the tax credit
carryforwards relate to exercises of non-qualified stock options and
disqualifying dispositions of incentive stock options, the tax benefit of which,
if realized, will be credited to additional paid-in-capital.

    Genzyme General's results of operations are highly dependent on sales of
Ceredase-Registered Trademark- and Cerezyme-Registered Trademark- enzymes. Sales
of these products represented 84% of Genzyme General's product revenue in 1999,
81% of product revenue in 1998, and 78% of product revenue in 1997. Genzyme
General sells these products directly to physicians, hospitals and treatment
centers as well as through unaffiliated distributors. Sales to one distributor
represented 20% of Ceredase-Registered Trademark- and
Cerezyme-Registered Trademark- enzyme revenues in 1999, 19% of these revenues in
1998, and 18% of these revenues in 1997. We believe that our credit risk
associated with trade receivables is mitigated as a result of the fact that
these products are sold to a large number of customers in a number of different
industries and over a broad geographic area.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of Genzyme Corporation:

    In our opinion, the accompanying combined balance sheets and the related
combined statements of operations and of cash flows present fairly, in all
material respects, the financial position of Genzyme General (as described in
Note A) at December 31, 1999 and 1998, and the results of its operations and its
cash flows for each of the three years in the period ended December 31, 1999, in
conformity with accounting principles generally accepted in the United States.
In addition, in our opinion, the financial statement schedule presents fairly,
in all material respects, the information set forth therein when read in
conjunction with the related combined financial statements. These financial
statements and financial statement schedule are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements and financial statement schedule based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

    As more fully described in Note A to these financial statements, Genzyme
General is a division of Genzyme Corporation; accordingly, the combined
financial statements of Genzyme General should be read in conjunction with the
audited consolidated financial statements of Genzyme Corporation and
Subsidiaries.
