- ------------------------
(1) In October 1992, Genzyme acquired all the outstanding common shares of
Vivigen, Inc. ("Vivigen") in a transaction accounted for as a pooling of
interests. Accordingly, Genzyme's financial data has been restated to include
Vivigen for all periods presented.

(2) In 1992, 1993, 1994 ,1995 and 1996, respectively, Genzyme acquired all of
the rights to four of the Neozyme I Corporation ("Neozyme I") development
programs and Medix Biotech, Inc. ("Medix"); all of the rights to the remaining
two Neozyme I development programs; all of the outstanding stock of BioSurface
Technology, Inc. ("BioSurface"); the publicly-held, minority interest in IG; and
the assets of Deknatel Snowden Pencer, Inc. ("DSP") and all of the Callable
Common Stock of Neozyme II Corporation ("Neozyme II"). In connection with these
transactions, all of which were accounted for as purchases, Genzyme charged to
operations the following amounts which represented the purchase of in-process
research and development: 1992, $51.1 million; 1993, $49.0 million, 1994, $11.2
million, 1995, $14.2 million and in 1996, $130.6 million.

(3) In 1993, the Company incurred restructuring charges of $2.8 million related
to the consolidation of laboratory operations in its diagnostic services
business and wrote off $23.7 million for the value of impaired goodwill
associated primarily with IG's acquisition of Genetic Design, Inc. ("GDI") in
1992. In 1996, the Company incurred additional restructuring charges of $1.0
million related to the consolidation of laboratory operations in its diagnostic
services business and $0.5 million related to the consolidation of foreign
operations in its surgical products business in connection with certain
acquisitions. 
   
(4) In 1992, Genzyme sponsored formation of Neozyme II. In connection with this
transaction, Genzyme obtained the option to acquire all of the equity of Neozyme
II under certain circumstances in exchange for the issuance of warrants to
acquire the Company's stock. The value assigned to this option ($16.9 million)
was charged to operations in the period the option was obtained due to
uncertainty as to Genzyme's future exercise of this option.

(5) Net income (loss) attributable to the General Division and the Tissue Repair
Division and net income (loss) per share for the years ended December 31, 1992,
and 1993 give effect to the management and accounting policies adopted by the
Board in connection with the creation of GTR and, accordingly, are pro forma
presentations.

distributed to stockholders in connection with the dividend. All share and per

long-term investments.

subordinated notes due October 2001 and received net proceeds of $97.3 million.
The notes were converted into shares of GGD Stock in March 1996. In June 1996,

There were no cash dividends paid.

- ------------------
(1) In October 1992, the General Division acquired all the outstanding common
shares of Vivigen, Inc. ("Vivigen") in a transaction accounted for as a pooling
of interests. Accordingly, the General Division's financial data has been
restated to include Vivigen for all periods presented.

(2) In 1992, 1993, 1994 and 1995, respectively, the General Division acquired
all of the rights to four of the Neozyme I Corporation ("Neozyme I") development
programs and Medix Biotech, Inc. ("Medix"); all of the rights to one of the two
remaining Neozyme I development programs; all of the outstanding stock of
BioSurface Technology, Inc. ("BioSurface"); the publicly-held, minority interest
in IG; and the assets of Deknatel Snowden Pencer, Inc. ("DSP") and all of the
Callable Common Stock of Neozyme II Corporation ("Neozyme II"). In connection
with these transactions, all of which were accounted for as purchases, Genzyme
charged to operations the following amounts which represented the purchase of
in-process research and development: 1992, $51.1 million; 1993, $49.0 million,
1994, $11.2 million, 1995, $14.2 million and in 1996, $130.6 million.

(3) In 1993, the General Division incurred restructuring charges of $2.8 million
related to the consolidation of laboratory operations in its diagnostic services
business and wrote off $23.7 million for the value of impaired goodwill

1992. In 1996, the General Division incurred additional restructuring charges of
$1.0 million related to the consolidation of laboratory operations in its
diagnostic services business and $0.5 million related to the consolidation of
foreign operations in its surgical products business in connection with certain
acquisitions.

(4) In 1992, the General Division sponsored formation of Neozyme II. In
connection with this transaction, the General Division obtained the option to
acquire all of the equity of Neozyme II under certain circumstances in exchange
for the issuance of warrants to acquire the General Division's stock. The value
assigned to this option ($16.9 million) was charged to operations in the period
each option was obtained due to uncertainty as to the General Division's future
exercise of this option.

(5) Net income (loss) attributable to General Division Stock and net income
(loss) per common and common equivalent share for the years ended December 31,
1992, and 1993 give effect to the provisions of Management and Accounting
Policies adopted by the Board in connection with the creation of GTR and
accordingly, are pro forma presentations.

effected by means of a 100% stock dividend paid to stockholders of record on
July 11, 1996. A total of 34,669,435 shares of General Division Stock were
distributed to stockholders in connection with the dividend. All share and per
share amounts have been re-stated to reflect this split.

(7) Cash and investments includes cash, cash equivalents, and short- and
long-term investments.

(8) In October 1991, the Company issued $100.0 million of 6 3/4% convertible
subordinated notes due October 2001 and received net proceeds of $97.3 million.
The notes were converted into shares of GGD Stock in March 1996. In June 1996,
the Company's $15.0 million credit line with a commerical was increased to
$215.0 million in connection with the acquisition of Deknatel Snowden Pencer,
Inc. ("DSP") in July 1996. In November 1996, this credit line was re-financed
with a syndicated group of banks and the revolving line of credit was increased
to $225.0 million. As of December 1996, the Company borrowed $218.0 million
under this credit facility of which $200.0 million was allocated to the General
Division and $18.0 million to GTR to finance operations. In July 1996, Genzyme
made a final payment of approximately $7.6 million for a company acquired in
1994.

(9) In December 1994, the outstanding shares of Genzyme common stock were
redesignated as General Division Common Stock on a share-for-share basis and a
second class of common stock designated as Tissue Repair Common Stock ("TR
Stock") was distributed on the basis of .135 of one share of TR Stock for each
share of Genzyme's previous common stock held by shareholders of record on
December 16, 1994. In October 1995, the General Division completed the sale of
5,750,000 shares of General Division Stock for net proceeds of $141.3 million.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
          RESULTS OF OPERATIONS.

INTRODUCTION

     This discussion contains forward-looking statements within the meaning of
Section 21E of the Securities Exchange Act of 1934, as amended. These
forward-looking statements represent the expectations of Genzyme's management as
of the filing date of this Form 10-K. The Company's 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". Stockholders and potential investors should consider
carefully these risks and uncertainties in evaluating Genzyme's financial
condition and results of operations.

     Genzyme provides its stockholders with three separate sets of financial
statements: one for the Company and its subsidiaries on a consolidated basis and
one for each of Genzyme General and Genzyme Tissue Repair. The financial
statements of each division include the financial position, results of
operations and cash flows of programs and products allocated to the division
under the Company's Articles of Organization, as amended (the "Genzyme
Charter"), and the management and accounting policies adopted by the Genzyme
Board of Directors (the "Genzyme Board") to govern the relationship of the
divisions. The financial information of Genzyme General and Genzyme Tissue
Repair, taken together, include all accounts which comprise the consolidated
financial information presented for Genzyme and its subsidiaries.

     For purposes of financial statement presentation, all of the Company's
programs, products, assets and liabilities are allocated to either Genzyme
General or Genzyme Tissue Repair. Notwithstanding this allocation, Genzyme
continues to hold title to all of the assets and is responsible for all of the
liabilities allocated to each of the divisions. Holders of Genzyme General Stock
and Genzyme Tissue Repair Stock have no specific claim against the assets
attributed to the division whose performance is associated with the class of
stock they hold. Liabilities or contingencies of either division that affect
Genzyme's resources or financial condition could affect the financial condition
or results of operations of both divisions. Stockholders and potential investors
should, therefore, read this discussion and analysis of financial position and
results of operations in conjunction with the financial statements and related
notes of Genzyme, Genzyme General and Genzyme Tissue Repair included with this
Form 10-K.

RESULTS OF OPERATIONS

   GENZYME CORPORATION AND SUBSIDIARIES

          Since the operating results of Genzyme and its subsidiaries reflect
the combined operations of Genzyme General and Genzyme Tissue Repair, this
discussion summarizes the key factors management considers necessary in
reviewing Genzyme's consolidated results of operations. Detailed discussion and
analysis of each division's results of operations are provided below under
separate headings.

          1996 COMPARED TO 1995

          REVENUES. Total revenues for 1996 were $518.8 million, an increase of
35% over 1995. Product revenues consist of product sales by Genzyme General and
increased 39% to $424.5 million in 1996. The increase resulted primarily from
the addition of sales from DSP and to increased sales of Ceredase(R) enzyme and
Cerezyme(R) enzyme.


          Service revenues consist of sales of genetic testing services by
Genzyme Genetics and sales of Genzyme Tissue Repair's CARTICEL(R) and EpicelSM
Services. Service revenues in 1996 increased 31% to $69.0 million, resulting
largely from higher unit volumes at Genzyme Genetics, due primarily to the
acquisition of Genetrix.

          Revenues from research and development contracts for 1996 were
attributable entirely to Genzyme General and decreased 6% to $25.3 million due
to the loss of revenues from Neozyme II as a result of its acquisition by the
Company in the fourth quarter.

          MARGINS AND OPERATING EXPENSES. Gross margins for 1996 were 57%,
compared to 58% for 1995. Product margins for 1996 were 63%, level with 1995, as
increased sales of higher margin products from the Company's existing product
lines were offset by lower margin product lines acquired with DSP. Service
margins for 1996 decreased to 22% 



                                       8
<PAGE>   9

from 32% due primarily to increased costs associated with Genzyme Tissue
Repair's sales of the CARTICEL(R) Service and increased costs during the
consolidation period associated with Genzyme General's acquisition of Genetrix.

   
          Selling, general and administrative ("SG&A") expenses for 1996 were
$162.3 million, an increase of 47% over 1995. The increase resulted primarily
from the acquisitions of DSP and Genetrix and increased staffing in support of
the growth in several product lines and the growth in sales of the CARTICEL(R)
Service.
    

          Research and development expenses for 1996 were $80.8 million, an
increase of 17% over 1995 due to Genzyme General's commitment to fund
development costs of the ATIII program being conducted by GTC and increased
spending on internal programs.

          Genzyme recorded the following acquisition-related charges in 1996:
$24.2 million and $106.5 million for the purchase of in-process research and
development in connection with the acquisitions of DSP and Neozyme II,
respectively; $8.8 million for the amortization of intangible assets including
goodwill recorded in connection with the acquisitions of DSP, Genetrix and, in
1995, the publicly-held, minority interest in IG Laboratories, Inc. ("IG"); and
$1.5 for restructuring charges incurred in connection with the acquisitions of
DSP and Genetrix.

          OTHER INCOME AND EXPENSES. Other income and expenses decreased 24% to
$5.7 million, as increases in interest expenses and Genzyme's equity in the net
loss of GTC offset a 74% increase in investment income. Interest expense for
1996 was $7.0 million, compared to $1.1 million in 1995. The increase resulted
from interest on funds borrowed to finance portions of the acquisitions of DSP
and Neozyme II.

          The tax provision for 1996 varies from the U.S. statutory tax rate
because of the provision for state income taxes, nondeductible intangible
amortization, losses of unconsolidated affiliates, benefits from operating loss
carryforwards and nondeductible charges in connection with tax-free
acquisitions. In 1996, the effective tax rate before these acquisitions was 41%,
compared to 37% in 1995. The increase in the rate was due to higher
nondeductible intangible amortization in 1996 and to lower benefits from
operating loss carryforwards available in 1996. The tax provision in 1996
resulted from taxes on foreign earnings and taxes on earnings before
acquisition-related charges comprising charges for intangible amortization and
incomplete technologies accruing from the acquisitions of DSP and Genetrix.

          1995 COMPARED TO 1994

          REVENUES. Total revenues for 1995 were $383.8 million, an increase of
23% over 1994. Product revenues from Genzyme General in 1995 increased 28% to
$304.4 million. The increase resulted primarily from increased sales of
Ceredase(R) enzyme and Cerezyme(R) enzyme and increased product sales by the
Pharmaceuticals and Diagnostic Products business units.

          Service revenues in 1995 increased 4.9% to $52.5 million, as the
addition of a full year of revenues from the acquisition of BioSurface
Technology, Inc. ("BioSurface"), acquired in December 1994, offset a 5% decline
in Genzyme General's sales of genetic testing services.

          Revenues from research and development contracts for 1995 were $27.0
million, an increase of 20% from 1994. Revenues from Neozyme II increased 36% to
$24.2 million due primarily to increased activity from collaborations with third
parties and increased clinical trial activity.

          MARGINS AND OPERATING EXPENSES. Gross margins for 1995 were 58%,
compared to 57% for 1994. Product margins for 1995 increased to 63% from 61% in
1994 due primarily to higher margins on Ceredase(R) enzyme and to the sale of
higher margin products and cost reductions by the Genzyme General's
Pharmaceuticals business unit. Service margins for 1995 decreased to 32% from
35% due primarily to increased costs associated with introduction of the
CARTICEL(R) Service by Genzyme Tissue Repair and price pressure on genetic
testing services at Genzyme General.

   
          SG&A expenses for 1995 were $110.4 million, an increase of 36% over
1994. The increase resulted primarily from increased staffing in support of the
growth in several product lines, the launch of the CARTICEL(R) Service by
Genzyme Tissue Repair and ongoing operating expenses associated with Sygena A.G.
("Sygena"), a Swiss pharmaceutical company acquired by Genzyme General in July
1994.
    



                                       9
<PAGE>   10

          Research and development expenses for 1995 were $68.8 million, an
increase of 24% over 1994 due to increased efforts on behalf of Neozyme II and
increased spending on internal programs.

          Genzyme recorded a charge in 1995 of $14.2 million for the purchase of
in-process research and development in connection with the acquisition of IG.

   
          OTHER INCOME AND EXPENSES. Other income (expenses) were $7.5
million, compared to of ($3.4 million) in 1994 that was attributable to the
write-off of impaired value of certain equity investments in the amount of $9.4
million and the settlement of a lawsuit with a payment of $2.0 million. Interest
expense for 1995 was $1.1 million, net of capitalized interest of $9.0 million.
Interest relating to Genzyme's 6 3/4% convertible subordinated notes was $6.8
million. These notes were converted to General Division Stock and GTR Stock in
March 1996.
    

          The tax provision for 1995 varies from the U.S. statutory tax rate
because of the provision for state income taxes, losses of majority-owned
subsidiaries which generated no current tax benefit, tax credits and taxes on
foreign earnings. The effective tax rate for 1995 was 50%, compared to 47% in
1994, largely due to the non-deductibility of the charges for in-process
research and development of $14.2 and $11.2 in 1995 and 1994, respectively. The
remainder of the increase was due to changes in U.S. versus foreign taxable
income.

   GENZYME GENERAL

          1996 COMPARED TO 1995

          REVENUES. Total revenues for 1996 were $511.4 million, an increase of
35% over 1995. Product and service revenues were $486.1 million, an increase of
38% over 1995. Revenues from research and development contracts for 1996 were
$25.3 million, a decrease of 6% from 1995.

          Product revenues in 1996 increased 39% to $424.5 million, due
primarily to the addition of sales through the acquisition DSP and to increased
sales of Ceredase(R) enzyme and Cerezyme(R) enzyme. Increases in sales by each
of the Diagnostic Products and Pharmaceuticals business units accounted for the
remainder of the increase in product revenues in 1996.

          Sales of Specialty Therapeutic products in 1996 consisted entirely of
sales of Ceredase(R) enzyme and Cerezyme(R) enzyme. Sales of Ceredase(R) enzyme
and Cerezyme(R) enzyme in 1996 increased 23% to $264.6 million due to increased
shipments resulting from the introduction of these products in Japan and
continued growth in new patient accruals in existing markets. Genzyme General's
results of operations are highly dependent on sales of Ceredase(R) enzyme and
Cerezyme(R) enzyme, which together represented 62% of consolidated product sales
in 1996 compared to 71% in 1995. In October 1996, Genzyme General received FDA
approval to manufacture Cerezyme(R) enzyme in a new, large-scale manufacturing
plant located in Boston, Massachusetts. Conversion of patients receiving
Ceredase(R) enzyme to Cerezyme(R) enzyme commenced in the fourth quarter of
1996. Genzyme General will be required to continue manufacturing Ceredase(R)
enzyme until the process of patient conversions is completed, which is expected
to occur during the fourth quarter of 1998. Genzyme General may be required to
record a charge to earnings for the inventory of Ceredase(R) enzyme remaining
upon completion of the patient conversion process, if any.

          The Surgical Products business unit was formed in July 1996 by
combining the business of DSP with Genzyme General's Sepra Products. Product
sales by the Surgical Products business unit for the period beginning with the
DSP acquisition on July 1, 1996 and ending December 31, 1996 were $50.7 million
and were generated primarily from sales by DSP. DSP's product sales for the
first half of 1996 and for the years ending December 31, 1995 and 1994, which
are not included in the results of Genzyme General, were $53.2 million, $95.2
million and $90.5 million, respectively.

          During the third quarter of 1996, the FDA granted approval to market
Seprafilm(TM) in the United States. Seprafilm(TM) is the first Sepra Product to
obtain FDA marketing approval and was launched broadly in the United States
during the fourth quarter. Seprafilm(TM) is being marketed in the United States
and Canada by Genzyme General on behalf of the Joint Venture between Genzyme and
GDP. In March 1997, Genzyme and GDP reached agreement concerning the operation
of and allocations of profits and losses from the Joint Venture. Under the terms
of this agreement, Genzyme will act as the sole distributor of the Sepra
Products for the Joint Venture, purchasing products from the joint venture at a
distributor discount, earning reimbursement for market introduction costs
and, in the first year in which the Joint Venture generates revenues in excess
of $25 million, reimbursement for general and administrative expense. Genzyme
has agreed to indemnify the limited partners against loss of tax benefits from
research and development deductions certain limited partners have taken. (See
"Business--Related Entities--Genzyme Development Partners, L.P."). Genzyme
consolidates 100% of the losses generated by the Joint Venture.



                                      10
<PAGE>   11

GDP will receive the first $5.6 million in profits generated by the Joint
Venture, Genzyme will receive the next $8.4 million in profits and, thereafter,
Genzyme and GDP will receive 60% and 40% shares, respectively, in the profits of
the Joint Venture.

          Product sales by the Diagnostic Products and Pharmaceuticals business
units increased 15% and 45%, respectively, over 1995. The increase in Diagnostic
Products sales resulted from growth in each of its product lines, most notably
in sales of the Direct LDL[TM] test and diagnostic intermediates. The increase
in Pharmaceuticals sales was generated primarily from sales of Melatonin during
the first half of 1996 and from sales of pharmaceutical grade HA Powder.
Melatonin sales declined materially during the second half of 1996 due to
declining market demand. Genzyme General does not expect that Melatonin sales
will return to the levels experienced during the first half of 1996.

          Revenues for Genzyme Genetics in 1996 increased 31% to $61.6 million,
due to higher unit volumes that were primarily attributable to the acquisition
of Genetrix, which was included in Genzyme General's results of operations from
May 1, 1996 forward, and to changes in service pricing. On November 1, 1996, the
assets of Genzyme General's identity testing services laboratory, Genetic
Design, Inc. ("GDI"), were sold. GDI contributed $11.6 in Genzyme Genetics
revenues through October 31, 1996.

          International sales as a percentage of total sales in 1996 decreased
to 35% from 36% in 1995, as the addition of domestic sales by DSP offset a 35%
increase in combined international sales of Ceredase(R) enzyme and Cerezyme(R)
enzyme.

          Revenues from research and development contracts for 1996 decreased 6%
to $25.3 million, as a decrease in revenues from Neozyme II was partially offset
by an increase in revenues from research and development contracts with other
third parties. Revenues from Neozyme II decreased 18% to $19.8 million in 1996
due to the acquisition of Neozyme II in the fourth quarter. Genzyme General
expects that revenues from research and development contracts in 1997 will
decrease from 1996 due to the absence of revenues from Neozyme II unless Genzyme
General establishes additional collaborations that will provide significant
research and development funding in 1997.

          MARGINS AND OPERATING EXPENSES. Gross margins for 1996 were 59%, level
with 1995. Genzyme General provides a broad range of health care products and
services, resulting in a range of gross margins depending on the particular
market conditions of each product or service. Product margins for 1996 were 63%,
level with 1995, as sales of higher margin products and cost reductions by both
the Pharmaceuticals and Diagnostic Products business units and higher margins on
Ceredase(R) enzyme resulting from manufacturing process improvements were offset
by lower margin product lines acquired with DSP. Service margins for 1996
decreased to 30% from 34% in 1995 due to the consolidation of Genzyme Genetics
with Genetrix, which require the operation of redundant facilities and staffing
until the consolidation is completed. Genzyme General expects service margins to
improve during 1997 due to the sale of GDI and the realization of economies of
scale from the consolidation of testing operations.

   
          SG&A expenses for 1996 were $135.2 million, an increase of 39% over
1995. The increase was due primarily to the acquisitions of DSP and Genetrix and
increased staffing in support of the growth in several product lines, most
notably in support of the North American introduction of the SeprafilmTM. DSP
added $12.1 million in SG&A expenses in 1996. For the first half of 1996 and for
1995 and 1994, DSP incurred SG&A expenses of $15.7 million, $25.3 million and
$27.6 million, respectively, which are not included in the results of Genzyme
General. Genetrix did not contribute materially to SG&A expenses in 1996 due to
the consolidation of its operations with Genzyme Genetics.
    

          Research and development expenses for 1996 were $70.0 million, an
increase of 21% over 1995 due to Genzyme General's funding of development costs
of the ATIII program being conducted by GTC and increased spending on internal
programs, most notably Thyrogen(R).

          Genzyme recorded charges related to the following acquisitions
completed in 1996:

          GENETRIX. On May 1, 1996, Genzyme acquired Genetrix in exchange for
approximately 1,380,000 shares of Genzyme General Stock valued at approximately
$36.5 million. Genzyme General recorded a charge in 1996 of $1.5 million for
amortization of goodwill and a restructuring charge of $1.0 million in
connection with the Genetrix acquisition.



                                      11
<PAGE>   12

          DSP. On July 1, 1996, Genzyme acquired DSP for cash in the amount of
$192.0 million, incurred acquisition costs in the amount of $4.6 million and
assumed debt obligations of DSP of approximately $55.6 million. Genzyme General
recorded charges of $24.2 million for the purchase of in-process research and
development and $0.5 million for restructuring in connection with the
acquisition of DSP.

          NEOZYME II. On October 28, 1996, Genzyme, through a wholly-owned
subsidiary ("Acquisition Corp.") completed a tender offer for outstanding Units
of Neozyme II for $45 per Unit in cash. A total of 2,385,686 Units, or 98.8%,
were tendered and accepted for payment. Each Neozyme II Unit consisted of one
share of Callable Common Stock and one Callable Warrant to purchase two shares
of Genzyme General Stock and 0.135 share of Genzyme Tissue Repair Stock. On
December 6, 1996, Neozyme II was merged with Acquisition Corp. and the remaining
outstanding shares of Callable Common Stock (other than shares held by
Acquisition Corp.) were thereby cancelled and converted into the right to
receive $29.00 per share in cash. The Callable Warrants included in the
untendered Units separated from the shares of Callable Common Stock converted in
the merger and became exercisable on December 6, 1996. Genzyme General recorded
a charge of $106.5 million for the purchase of in- process research and
development in connection with the acquisition of Neozyme II.

          OTHER INCOME AND EXPENSES. Other income (expense) decreased less
than 1% to $6.1 million, as increases in interest expenses offset an 87%
increase in investment income. Investment income for 1996 was $13.9 million,
compared with $7.4 million for 1995. The increase resulted from higher average
cash and investment balances. Investment income for 1996 did not include any
material gain or loss on sales of securities. Interest expense for 1996 was $6.8
million, compared to $1.1 million in 1995. The increase resulted from interest
on funds borrowed to finance portions of the acquisitions of DSP and Neozyme II
and lower capitalized interest in 1996 than in 1995.

   
          The tax provision for 1996 varies from the U.S. statutory tax rate
because of the provision for state income taxes, losses of unconsolidated
affiliates, nondeductible intangible amortization, benefits from operating loss
carryforwards and nondeductible charges in connection with tax-free
acquisitions. In 1996, the effective tax rate before these acquisitions was 41%,
compared to 38% in 1995. The increase in the rate was due to higher
nondeductible intangible amortization in 1996 and to lower benefits from
operating loss carryforwards available in 1996. The tax provision in 1996
resulted from taxes on foreign earnings and taxes on earnings before
acquisition-related charges comprising charges for intangible amortization and
incomplete technologies accruing from the acquisitions of DSP of Genetrix. The
allocated tax benefit generated by Genzyme Tissue Repair of $17.0 million in
1996 and $8.9 million in 1995 reduced Genzyme General's tax rate to 12% and
33%, respectively.
    

          1995 COMPARED TO 1994

          REVENUES. Total revenues for 1995 were $378.6 million, an increase of
22% over 1994. Product and service revenues were $351.6 million, an increase of
22% over 1994. Revenues from research and development contracts for 1996 were
$27.0 million, an increase of 20% from 1994.

          Product revenues for 1995 increased 28% to $304.4 million, due
primarily to increased sales of Ceredase(R) enzyme and Cerezyme(R) enzyme.
Increases in sales by each of the Diagnostic Products and Pharmaceuticals
business units accounted for the remainder of the increase in product revenues
in 1995.

   
          Sales of Specialty Therapeutic products in 1995 consisted primarily of
sales of Ceredase(R) enzyme and Cerezyme(R) enzyme. HA Powder sales were
reclassified as Pharmaceuticals product sales beginning in the fourth quarter of
1995. Sales of Ceredase(R) enzyme and Cerezyme(R) enzyme in 1995 increased 25%
to $215.4 million due to increased shipments of these products, for which the
rate of new patient accruals more than offset dosage reductions. Ceredase(R)
enzyme and Cerezyme(R) enzyme, together, represented 71% of consolidated product
sales in 1995 compared to 72% in 1994.
    

          Product sales by the Diagnostic Products and Pharmaceuticals business
units increased 22% and 72%, respectively, over 1994. The increase in Diagnostic
Products sales resulted from growth in each of its product lines, most notably
in sales of the Direct LDLTM test sales. The increase in Pharmaceuticals sales
was generated primarily from sales of Melatonin during the second half of 1995
and a full year of operations of Sygena.

          Revenues for the Diagnostic Services business unit in 1995 decreased
5% to $47.2 million from $49.7 million for 1994. The drop in service revenues
resulted from declines in identity testing revenues at GDI and the impact of
increasing price pressures on the public paternity testing services performed by
GDI. Medical testing also experienced increased price competition due to
increases in the number of HMO contracts.



                                      12
<PAGE>   13

          International sales represented approximately 36% of total sales in
1995 compared with 31% in 1994. This increase was due primarily to a 49%
increase in the combined international sales of Ceredase(R) enzyme and
Cerezyme(R) enzyme.

          Revenues from research and development contracts for 1995 were $27.0
million, an increase of 20% from 1994. Revenues from Neozyme II increased 36% to
$24.2 million for 1995 due primarily to increased activity relating to
collaborations with third parties that began in 1993 along with the production
of clinical trial material.

          MARGINS AND OPERATING EXPENSES. Gross margins for 1995 were 59%,
compared to 57% for 1994. Product margins for 1995 increased to 63% from 61% in
1994 due to higher margins on Ceredase(R) enzyme resulting from raw material
yield improvements and to sales of higher margin products and cost reductions by
the Pharmaceuticals business unit. Service margins for 1995 decreased to 34%
from 35% as economies achieved in the consolidation of testing activities did
not fully offset lower sales volume and the effects of price competition.

   
          SG&A expenses for 1995 were $97.5 million, an increase of 22% over
1994. The increase was due primarily to increased staffing in support of the
growth in several product lines, most notably in support of the European
introduction of the Sepra Products, and to the ongoing operating expenses
associated with Sygena.
    

          Research and development expenses for 1995 were $57.9 million, an
increase of 12% over 1994 due to increased efforts on behalf of Neozyme II and
increased spending on internal programs, including the Sepra Products.


          In October 1995, Genzyme General acquired the publicly-held,
minority interest in IG for 770,000 shares of Genzyme General Stock valued at
approximately $22.5 million. The acquisition was accounted for as a purchase.
The excess of the purchase price over the fair market value of the net assets
acquired was approximately $18.6 million of which $14.2 million was attributed
to incomplete technology and charged to operations and the balance to goodwill
to be written off over 11 years.

          OTHER INCOME AND EXPENSES. Other income and expenses were $6.2
million, compared to a loss of $3.4 million in 1994 that was attributable to the
write-off of impaired value of certain equity investments in the amount of $9.4
million and to settlement of a lawsuit for $2.0 million. In September 1995,
Genzyme General recorded a gain of $950,000 representing the sale of certain
assets by GTC.

          Investment income for 1995 was $7.4 million, compared with $9.1
million for 1994. The decrease resulted from lower average cash and investment
balances. Investment income for 1995 included a loss of $0.1 million and 1994
included gains of $1.4 million on sales of securities.

          Interest expense for 1995 was $1.1 million, net of capitalized
interest of $9.0 million. Interest relating to the Company's 6 3/4% convertible
subordinated notes was $6.7 million. These notes were converted into General
Division and Tissue Repair Division Stock in March, 1996.


          The tax provision for 1995 varies from the U.S. statutory tax rate
because of the provision for state income taxes, losses of majority-owned
subsidiaries which generate no current tax benefit, tax credits and taxes on
foreign earnings. The effective tax rate was 47% for 1995 compared to 35% for
1994. The increase was due to changes in U.S. versus foreign taxable income and
to certain charges recorded in 1995 for which Genzyme General received no tax
benefit. The allocated tax benefit generated by Genzyme Tissue Repair of $8.9
million in 1995 and $1.9 million in 1994 reduced Genzyme General's tax rate to
33% and 31%, respectively.

   GENZYME TISSUE REPAIR

          1996 COMPARED TO 1995

          REVENUES. Revenues in 1996 increased 40% to $7.3 million from $5.2
million in 1995. Sales of the CARTICEL(R) Service were $3.1 million, compared to
$0.6 million in 1995, the year in which the Service was launched. The increase
in CARTICEL(R) Service sales resulted primarily from the increase in the number
of surgeons trained in the procedure utilizing the service. Sales of the
Epicel(SM) Service in 1996 decreased 9% to $4.2 million, due to a decrease in
the number of burn incidents requiring the Service.



                                      13
<PAGE>   14

          MARGINS AND OPERATING EXPENSES. Genzyme Tissue Repair's costs of
services sold exceeded revenues by 53% in 1996, compared to a gross profit of 9%
in 1995, due to increased spending for the expansion of manufacturing capacity.

          SG&A expenses in 1996 were $27.1 million, an increase of 110% over
1995. The increase resulted from the expenses and staffing to support revenue
growth and increased surgeon training costs related to the CARTICEL(R) Service.
Genzyme Tissue Repair incurs direct SG&A expenses as well as an SG&A charge,
based on actual amounts incurred, from Genzyme General for SG&A work performed
by Genzyme General on behalf of Genzyme Tissue Repair. In 1996, $9.1 million of
SG&A services were provided by Genzyme General, compared to $4.4 million in
1995, due to an increase in the level of operations related to the CARTICEL(R)
Service.

          Research and development expenses were $10.9 million in each of 1996
and 1995. Increases in expenses associated with the TGF-(beta)2 program were
offset by decreases in the Vianain(R) program. In 1996, $6.9 million of research
and development services were provided by Genzyme General to Genzyme Tissue
Repair, compared to $4.7 million in 1995.

          OTHER INCOME AND EXPENSES. Investment income was $1.4 million in each
of 1996 and 1995, due primarily to level average cash balances during the year.
Interest expense in 1996 was $.1 million, net of capitalized interest on
construction in progress of $.2 million, compared to $.05 million in 1995.
Interest expense increased in 1996 due to interest on borrowings. See "Liquidity
and Capital Resources--Genzyme Tissue Repair Division" for a description of the
borrowings.

          On October 1, 1996, Diacrin/Genzyme LLC was established as a joint
venture between Genzyme Tissue Repair and Diacrin to develop and commercialize
products and processes using porcine fetal cells for the treatment of
Parkinson's disease and Huntington's disease in humans. Under the terms of the
joint venture agreement, Genzyme Tissue Repair is required to provide 80% of the
first $50 million in funding for products to be developed by the joint venture.
Thereafter, all costs will be shared equally between Genzyme Tissue Repair and
Diacrin. Profits from the joint venture will be shared by the two parties. As of
December 31, 1996, Genzyme Tissue Repair had provided $1.9 million of funding to
the joint venture and realized a net loss of $1.7 million from the joint
venture. Genzyme Tissue Repair's funding commitment to the joint venture is
expected to be approximately $10 million for each of 1997 and 1998.

          1995 COMPARED TO 1994

   
          REVENUES. Revenues for 1995 were $5.2 million compared to $0.3 million
in 1994. Revenues in 1994 consisted solely of revenues from the sale of the
Epicel(SM) Service for the period from December 16, 1994, the acquisition date
of BioSurface, through December 31, 1994. Revenues for 1995 consisted primarily
of $4.6 million in sales of Epicel(SM) Service and $0.6 million from sales of
the CARTICEL(R) Service.
    

          MARGINS AND OPERATING EXPENSES. Gross margins decreased to 9% in 1995
from 11% in 1994 due to costs associated with the launch of the CARTICEL(R)
Service. SG&A expenses for 1995 were $12.9 million, compared to $1.0 million in
1994 comprised solely of expenses from BioSurface. In 1995, $4.4 million of SG&A
services were provided by Genzyme General to Genzyme Tissue Repair compared to
$0.8 million in 1994. The increases in SG&A expenses and services provided by
Genzyme General were due to a full year of operations from BioSurface and to the
launch in both the United States and Europe of the CARTICEL(R) Service.

          Research and development expenses for 1995 were $10.9 million compared
to $3.6 million in 1994 which included $0.3 million from the operations of
BioSurface. The increase resulted from accelerated clinical trials activity for
certain tissue repair products and increased efforts relating to the CARTICEL(R)
Service. In 1995, $4.7 million of research and development services were
provided by Genzyme General to Genzyme Tissue Repair compared to $3.3 million in
1994.

          OTHER INCOME AND EXPENSES. Investment income for 1995 was $1,386,000
compared to $29,000 for 1994. The increase over 1994 was due to higher average
cash balances from the allocation of $10 million from Genzyme General and the
net proceeds from a public offering in October 1995. In 1994, $11.2 million of
incomplete technology from the BioSurface acquisition was charged to operations
as in-process research and development.

LIQUIDITY AND CAPITAL RESOURCES

   GENZYME CORPORATION AND SUBSIDIARIES

   
     At December 31, 1996, Genzyme had cash, cash equivalents and marketable
securities of $188.0 million, excluding $87.0 million outstanding in respect of
certain warrants exercised immediately prior to year end and received by Genzyme
during the first week of January 1997, compared with $256.7 million at December
31, 1995, excluding long term investments of $69.6 million at December 31, 1995.
    

   
     Genzyme generated $40.0 million of cash from operations in 1996, compared
to $44.7 million in 1995 and $33.0 million in 1994. The decrease from 1995 
resulted primarily from increased losses at Genzyme Tissue Repair partially 
offset by lower working capital requirements in Genzyme General. Investing 
activities required cash of $292.2 million in 1996. Investing activities 
included the acquisition of DSP and Neozyme II for net cash of $303.3 million 
and $63.8 million of spending for property, plant and equipment, a 28% 
increase from 1995. This increase was primarily to build processing capability 
in Genzyme Tissue Repair for the CARTICEL service and in Genzyme General for 
completion of manufacturing capacity for Cerezyme(R), and for office and 
laboratory equipment. Turnover of the investment portfolio provided $85.3 
million in funding for these activities with the balance financed by a 
revolving line of credit and the exercise of options and warrants.
    

          In March 1996, Genzyme completed the conversion of its 6 3/4%
convertible notes in the principal amount of $100 million. Holders of the notes
received 18.183 shares of Genzyme General stock and 2.553 shares of Genzyme
Tissue Repair Stock upon conversion of each $1,000 note.

          In November 1996, Genzyme refinanced its existing $215 million line of
credit (the "Credit Line") with a revolving credit facility (the "Revolving
Facility") in the amount of $225 million made available through a syndicate of
commercial banks administered by Fleet National Bank. Amounts drawn under the
facility may be allocated to either Genzyme General or Genzyme Tissue Repair
depending upon which division uses the loan proceeds. At December 31, 1996, $218
million had been drawn under the Revolving Facility, of which $200 million was
allocated to Genzyme General to refinance amounts borrowed under the Credit Line
to fund portions of the DSP and Neozyme II acquisitions and $18 million was
allocated to Genzyme Tissue Repair to finance operations and manufacturing
capacity. Amounts borrowed under the Revolving Facility are payable on November
15, 1999.

          In December 1996, the Company entered into a $100 million interest
rate swap contract ("the Swap Contract") to effectively convert the variable
interest rate on borrowings under the Revolving Facility to fixed interest
rates. Net proceeds made or received under the Swap Contract are recorded as
adjustments to interest expense. At December 31, 1996 the Swap Contract had a
termination value gain of $125,000.

          Genzyme holds an option to acquire all of the partnership interests in
GDP for approximately $26 million plus a continuing royalty payment for a period
of ten years on certain sales of Sepra Products. Genzyme's decision regarding
the exercise of this option will be based, in part, on the progress in the
development and Genzyme's evaluation of the potential commercial success of the
Sepra Products. The exercise price for the purchase option is payable in cash,
shares of Genzyme General Stock or a combination of the two, as determined by
Genzyme at the time the option is exercised.

          Genzyme expects that its available cash, investments, cash flow from
research contracts and product and service sales and amounts available under the
Revolving Facility will be sufficient to finance its planned operations and
capital requirements for the foreseeable future. Genzyme's capital requirements
could differ materially from those currently anticipated by management due to
the factors described under the "Factors Affecting Future Operating
Results--Future Capital Needs".

   GENZYME GENERAL

   
          At December 31, 1996, Genzyme General had cash, cash equivalents and
marketable securities of $171.7 million, excluding $87.0 million outstanding in
respect of certain warrants exercised immediately prior to year end and received
by Genzyme during the first week of January 1997, compared with $209.1 million,
excluding $69.6 million in long-term investments at December 31, 1995. Genzyme
General generated $80.2 million of cash from operations in 1996, compared to
$64.1 million in 1995. The increase in 1996 over 1995 resulted from higher
profits prior to non-cash charges for incomplete technology and other
acquisition related, non-cash charges, and to lower increases in working
capital.
    

   
          At December 31, 1996, Genzyme General had accounts receivable of
$115.1 million, an increase of $28.0 million from December 31, 1995 due
primarily to the DSP and Genetrix acquisitions and growth in each of the General
Division's businesses. Accounts receivable at December 31, 1995 were $87.1
million, an increase of $10.5 million from December 
    



                                       15
<PAGE>   16

31, 1994 due primarily to the growth in product sales by Specialty Therapeutics
and Pharmaceuticals business units. At December 31, 1996, inventories increased
136% to $123.4 million, due primarily to the acquisition of DSP, increases in
Ceredase(R) enzyme and Cerezyme(R) enzyme inventories and Sepra Product
inventories in support of the launch Seprafilm(TM). Inventories at December 31,
1995 increased 42% to $52.3 million, compared to $36.8 million at December 31,
1994. The increase was due primarily to support of increased business
operations, most notably in the Specialty Therapeutics business unit to build
Ceredase(R) enzyme inventories, in the Pharmaceuticals business unit to meet
high demand for Melatonin and in anticipation of the launch of Seprafilm(TM).

   
          Investing activities required cash of $275.7 million in 1996 and
$145.8 million in 1995. The increase resulted from the acquisition of DSP and
Neozyme II for net cash of $303.3 million and spending for property, plant and
equipment of $42.5 million, a decrease of 13% from 1995 and 58% from 1994. The
decreases are due to lower rates of manufacturing capacity expansion and to the
completion of the large-scale Cerezyme(R) manufacturing capacity in Boston,
Massachusetts. Turnover of the investment portfolio provided $78.9 million in
funding for these activities with the balance financed by a revolving line of
credit and the exercise of options and warrants.
    

          Proceeds from the exercise of stock options, warrants and stock issued
through the employee stock purchase plan increased to $39.1 million in 1996,
compared to $38.3 million in 1995. The increase was due primarily to exercises
of certain warrants, issued in connection with the formation of GDP and Neozyme
II, prior to the scheduled termination of such warrants in October and December,
respectively.

          In March 1996, Genzyme entered into a Convertible Debt and Development
Funding Agreement with GTC under which Genzyme agreed to provide through Genzyme
General a revolving line of credit in the amount of $10 million through December
31, 1998 and to fund development costs of the AT-III program through March 31,
1997. The line of credit carries a rate of 7% and is convertible into GTC's
common stock at the average market price for the 20-trading day period ending
two days before the conversion (i) at GTC's option only to the extent necessary
to maintain GTC's tangible net worth at the end of each quarter at a level
between $4.0 million and $4.2 million or (ii) by Genzyme General at any time for
up to the full amount outstanding. Pursuant to the terms of this agreement, GTC
borrowed $4.3 million in 1996 from Genzyme General and converted $1.7 million of
this debt plus accrued interest into 219,565 shares of GTC stock. In addition,
on July 31, 1996, GTC sold 3,000,000 shares of its common stock to the public
for $4.00 per share. Genzyme General purchased 900,000 shares in the offering.

          Genzyme General expects that its available cash, investments and cash
flow from research contracts and product and service sales will be sufficient to
finance its planned operations and capital requirements for the foreseeable
future. Genzyme General's capital requirements could differ materially from
those currently anticipated by management due to the factors described under the
"Factors Affecting Future Operating Results--Future Capital Needs".

   GENZYME TISSUE REPAIR

   
          As of December 31, 1996, Genzyme Tissue Repair had cash and cash
equivalents of $16.2 million, a decrease of $31.3 million from December 31,
1995. In 1996, Genzyme Tissue Repair used $40.2 million of cash for operations
and $18 million for increased manufacturing capacity . These expenditures were
financed by the issuance of common stock through exercises of stock options and
warrants, $56 million from borrowings under the Revolving Facility, of which $38
million was repaid in 1996 and the allocation of $10 million from Genzyme
General as described below.
    

   
          As of December 31, 1996, Genzyme Tissue Repair had accounts receivable
of $1.7 million, a decrease of $.2 million from December 31, 1995. Inventories
increased $1 million to $1.8 million as of December 31, 1996 compared to
December 31, 1995. The increase resulted from an increase in the number of
in-process biopsies for the CARTICEL(R) Service.
    

          Under the terms of the BioSurface acquisition agreement, the Genzyme
Board may elect to allocate up to $30 million from Genzyme General to Genzyme
Tissue Repair in exchange for an increase in the Genzyme Tissue Repair
Designated Shares at a price of $10 per share. In June 1996, the Genzyme Board
voted to allocate $10 million under the agreement in exchange for an increase in
the Genzyme Tissue Repair Designated Shares of 1,000,000 shares.



                                       16
<PAGE>   17

          In August 1996, the Genzyme Board approved the reallocation of certain
of Genzyme Tissue Repair's Framingham real estate (land, buildings and leasehold
improvements) to Genzyme General for cash of $5.2 million, which was the fair
market value of the property as determined by the Genzyme Board and approximated
the property's cost.

          In order to provide initial funding for the joint venture with
Diacrin, the Genzyme Board has approved the allocation of up to $20 million in
cash from Genzyme General to Genzyme Tissue Repair (the "Genzyme Tissue Repair
Equity Line") in exchange for an increase in the number of Genzyme Tissue Repair
Designated Shares at a rate determined by dividing the amount of cash so
allocated by the average of the daily closing prices of one share of Genzyme
Tissue Repair Stock for the 20 consecutive trading days commencing on the 30th
trading day prior to the date of allocation. The Company intends to make monthly
allocations of cash under the Genzyme Tissue Repair Equity Line in an amount
corresponding to the funding commitment of Genzyme Tissue Repair under the joint
venture agreement for such month. As of December 31, 1996 the Company had
allocated $1.9 million from Genzyme General to Genzyme Tissue Repair under the
Genzyme Tissue Repair Equity Line.

          Genzyme Tissue Repair does not expect its available cash and
investments will be sufficient to finance planned operations and capital
requirements through the end of 1997 and must raise significant additional
capital in order to continue operations at current levels. Genzyme Tissue
Repair's plans to raise additional capital include consideration of the sale of
additional equity securities, strategic alliances with third parties to fund
further development and marketing of the CARTICEL(R) Service and other business
transactions that would generate capital resources to assure continuation of
Genzyme Tissue Repair's operations and research programs. Pursuant to these
initiatives, Genzyme Tissue Repair raised $13 million in March 1997 in a private
placement of a 5% note convertible into Genzyme Tissue Repair Stock. See
"Subsequent Events". Significant additional funds will be required to continue
operations at current levels through year end, however, and Genzyme Tissue
Repair may be required to delay, scale back or eliminate certain of its programs
or to license third parties to commercialize technologies or products that the
division would otherwise undertake itself if it is not successful in raising
additional capital.

SUBSEQUENT EVENTS

          In January 1997, Genzyme signed a merger agreement providing for the
merger of PharmaGenics, Inc., a company engaged in the research and development
of pharmaceuticals for the treatment of cancer, into Genzyme in exchange for
approximately 4,000,000 shares of a new Genzyme security to be designated
Genzyme Molecular Oncology Division Common Stock ("GMO Stock"). The GMO Stock is
intended to reflect the value and track the performance of Genzyme Molecular
Oncology, a new division proposed by Genzyme to develop and market novel
products and services for the diagnosis and treatment of cancer. The shares of
GMO Stock to be issued in the merger represent 40% of the initial equity
interest in Genzyme Molecular Oncology. The remaining 60% will be allocated to
Genzyme General in the form of 6,000,000 GMO Designated Shares. The merger is
subject to the approval of the stockholders of Genzyme and PharmaGenics.

          On February 27, 1997, Genzyme Tissue Repair raised $13 million through
the private placement with an institutional investor of a 5% convertible note
due February 27, 2000. The note is an unsecured obligation of Genzyme and is
convertible into Genzyme Tissue Repair Stock. The number of shares of Genzyme
Tissue Repair Stock into which principal of, and interest on, the note are
convertible depends on when a conversion occurs. For conversions occurring
during the period beginning August 28, 1997 and ending May 25, 1998, the
conversion shares are valued at a discount to an average of recent market prices
at the time of conversion. This discount increases monthly from 2% on August 28,
1997 to 11% on May 25, 1998. For conversions occurring after May 25, 1998, the
conversion shares are valued at an 11% discount to the lower of (i) the average
of recent market prices at the time of conversion and (ii) the average of the
market prices during the 25 trading days prior to May 25, 1998. Genzyme agreed
to file a resale registration statement covering sales of Genzyme Tissue Repair
Stock received upon conversion.

FACTORS AFFECTING FUTURE OPERATING RESULTS

          DEPENDENCE ON CEREDASE(R) AND CEREZYME(R) ENZYME SALES. Genzyme's
results of operations are highly dependent upon the sales of Ceredase(R) enzyme
and Cerezyme(R) enzyme. Sales of Ceredase(R) enzyme and Cerezyme(R) enzyme in
1996 were $264.6 million, representing 62% of consolidated product sales in
1996. Genzyme produces Ceredase(R) enzyme from an extract of human placental
tissue supplied by a French company that is the only significant commercial
source of this 



                                       17
<PAGE>   18

material. The current supply available is not sufficient to produce enough
Ceredase(R) enzyme to supply all present patients.

          To address supply constraints, Genzyme has developed Cerezyme(R)
enzyme, a recombinant form of the enzyme. In October of 1996, Genzyme General
received FDA approval to manufacture Cerezyme(R) enzyme in a new, large-scale
manufacturing plant located in Boston, Massachusetts. Once an uninterrupted
supply of Cerezyme(R) enzyme can be produced by the new plant, patients
receiving Ceredase(R) enzyme will be converted to Cerezyme(R) enzyme. Genzyme
General will be required to continue manufacturing Ceredase(R) enzyme until the
process of patient conversions is completed, which is expected to occur during
the fourth quarter of 1998. Any disruption in the supply or manufacturing
process of Ceredase(R) enzyme during the conversion period or in the supply or
manufacturing process of Cerezyme(R) enzyme may have a material adverse effect
on revenue.

          NO ASSURANCE OF COMMERCIAL SUCCESS OF THE SEPRA PRODUCTS. The
successful commercialization of the Sepra Products will depend on many factors,
including (i) the response of surgeons to the data from clinical trials, (ii)
Genzyme General's ability to deploy the sales force of DSP to market the Sepra
Products, (iii) Genzyme General's ability to supply sufficient product to meet
market demand and (iv) the number and relative efficacy of competitive products
that may subsequently enter the market. There can be no assurance that Genzyme
General will be successful in its efforts to implement a commercialization
strategy for the Sepra Products.

          NO ASSURANCE OF COMMERCIAL SUCCESS OF THE CARTICEL(R) SERVICE. Genzyme
Tissue Repair's future success depends in large part on the successful
commercialization of the CARTICEL(R) Service. The FDA has issued regulations
that will bring products and services such as the CARTICEL(R) Service under
regulation by November of 1997. Companies already marketing products and
services subject to the regulations are allowed a transition period ending on
November 30, 1997 in which to file and obtain approval of a Biologics License
Application (a "BLA"), while continuing to market their products and services.
Genzyme Tissue Repair submitted a BLA for the CARTICEL(R) Service in March 1996
in anticipation of the regulations. Although Genzyme Tissue Repair expects the
FDA to complete its review of the BLA before of the end of November 1997, there
can be no assurance that the review will be completed by then or that the FDA
will not require additional data concerning the safety and efficacy of the
CARTICEL(R) Service. A delay in the approval of the BLA for the CARTICEL(R)
Service beyond the transition period could materially and adversely affect the
commercialization of the CARTICEL(R) Service.

          The successful commercialization of the CARTICEL(R) Service will
depend materially on the ability of Genzyme Tissue Repair to obtain approval for
reimbursement of the CARTICEL(R) Service from third party payers. To date,
approvals for reimbursement applications have been lower than anticipated by
Genzyme Tissue Repair and, pending FDA approval of the BLA for the CARTICEL(R)
Service, there can be no assurance that the rate of such approvals will improve
or will not decline. There can also be no assurance that the approval rate will
improve if the BLA is approved. If the approval rate does not improve, the
commercialization of the CARTICEL(R) Service and Genzyme Tissue Repair's future
success may be adversely affected.

          COLLABORATION WITH DIACRIN; NO CURRENTLY APPROVED
XENOTRANSPLANTATION-BASED PRODUCTS; RELIANCE ON CELL TRANSPLANTATION TECHNOLOGY.
Genzyme Tissue Repair has formed a joint venture with Diacrin, Inc. to develop
and commercialize populations of transplantable porcine cells for the treatment
of Parkinson's and Huntington's diseases. Products based on xenotransplantation
such as the porcine cells being developed by the joint venture represent a novel
therapeutic approach that has not been subject to extensive clinical testing and
pose a risk that viruses or other animal pathogens will be unintentionally
transmitted to a human patient. The FDA has issued draft regulatory guidelines
to reduce the risk of contamination of xenotransplanted cellular products with
infectious agents. Although Genzyme Tissue Repair's management believes the
processes used to produce the porcine cell products under development by the
joint venture would comply with the guidelines as drafted, such guidelines may
undergo substantial revision before definitive guidelines are issued by the FDA.
There can be no assurance that definitive guidelines will be issued by the FDA
or that the processes used by the joint venture will comply with any guidelines
that may be issued.

          No xenotransplantation-based therapeutic product has been approved for
sale by the FDA and there can be no assurance that any products developed by the
joint venture will be approved by the FDA or regulatory authorities in other
countries. There can also be no assurance that xenotransplantation-based
products, including the joint venture's product candidates, will be accepted by
the medical community or third party payers or that the degree of such
acceptance will not limit the size of the market for such products.



                                       18
<PAGE>   19

          The success of the joint venture will also be dependent upon the
successful development of cell transplantation technology. This technology
currently has limited clinical applications and there can be no assurance that
it will result in the development of any therapeutic products. If the cell
transplantation technology does not result in the development of such products,
the joint venture may be required to change dramatically the scope and direction
of its product development activities.

   
          FUTURE CAPITAL NEEDS. Although Genzyme currently has substantial cash
resources, it has committed to utilize a portion of such funds for certain
purposes, such as (i) completing the market introduction in the United States
and Europe of the Sepra Products, (ii) completing the market introduction of
Genzyme Tissue Repair's CARTICEL(R) Service and developing, producing and
marketing other products through Genzyme Tissue Repair and (iii) making certain
payments to third parties in connection with strategic collaborations. At
December 31, 1996, Genzyme had approximately $275 million in cash and cash
equivalents and marketable securities, which amount includes $87.0 million in
respect of certain warrants exercised immediately prior to year end that was
received by Genzyme during the first week of January 1997, and approximately
$218 million outstanding under the Revolving Facility, $200 million of which was
allocated to Genzyme General. Amounts borrowed under this Revolving Facility are
payable on November 15, 1999. Genzyme's cash resources will be diminished upon
repayment of amounts borrowed, plus accrued interest, under the Revolving
Facility. In addition, should Genzyme exercise its option to acquire the
partnership interests in GDP using cash to pay some or all the exercise price,
its cash resources will be diminished. As a result, Genzyme may have to obtain
additional financing. There can be no assurance that such financing will be
available on terms reasonably acceptable to Genzyme.
    

          TISSUE REPAIR DIVISION OPERATING LOSSES AND CASH REQUIREMENTS. Genzyme
Tissue Repair is expected to experience significant operating losses at least
through the end of 1998 as the market introduction of the CARTICEL(R) Service
continues and as its research and development and clinical trial programs
expand, including its commitment to fund the operations of Diacrin/Genzyme LLC.
There can be no assurance that Genzyme Tissue Repair ever will achieve a
profitable level of operations or that profitability, if achieved, can be
sustained on an ongoing basis. The liabilities or contingencies of Genzyme
Tissue Repair affect Genzyme's resources or financial condition and could affect
the financial condition or results of operations of Genzyme General.

          POTENTIAL GENZYME TISSUE REPAIR STOCK DILUTION. Under the terms of the
BioSurface acquisition agreement, the Genzyme Board may elect to allocate up to
$30 million from Genzyme General to Genzyme Tissue Repair in exchange for an
increase in the Genzyme Tissue Repair Designated Shares at a price of $10 per
share. In June 1996, the Genzyme Board voted to allocate $10,000,000 under the
agreement in exchange for an increase in the Genzyme Tissue Repair Designated
shares of 1,000,000 shares. Although these shares have not yet been issued,
Genzyme may issue these and any additional Genzyme Tissue Repair Designated
Shares as a stock dividend to the holders of Genzyme General Stock or in a
public or private sale without any allocation of proceeds to Genzyme Tissue
Repair. In addition, in connection with the formation of the joint venture
between Genzyme Tissue Repair and Diacrin, Inc., the Genzyme Board authorized
the allocation of up to $20 million in cash from Genzyme General to Genzyme
Tissue Repair. Such allocations will result in an increase in the Genzyme Tissue
Repair Designated Shares by a number of shares determined by dividing (i) the
amount of cash allocated by (ii) the average of the daily closing prices of
Genzyme Tissue Repair Stock as reported by the Nasdaq National Market (or the
appropriate exchange on which such shares are then traded) for the 20
consecutive trading days commencing on the 30th day prior to the date of
allocation of such funds. The Genzyme Board has also adopted a policy for the
distribution of Genzyme Tissue Repair Designated shares providing that if, as of
May 31 of each year starting May 31, 1997, the number of Genzyme Tissue Repair
Designated Shares on such date (not including those reserved for issuance with
respect to stock options, stock purchase rights, warrants or other securities
convertible into or exercisable for shares of Genzyme General Stock outstanding
on such date ("Genzyme General Convertible Securities") as a result of
anti-dilution adjustments required by the terms of such instruments or approved
by the Genzyme Board) exceeds ten percent (10%) of the number of shares of
Genzyme Tissue Repair Stock then issued and outstanding, then substantially all
Genzyme Tissue Repair Designated Shares will be distributed to holders of record
of Genzyme General Stock subject to reservation of a number of such shares equal
to the sum of (a) the number of Genzyme Tissue Repair Designated Shares reserved
for issuance upon the exercise or conversion of Genzyme General Convertible
Securities and (b) the number of Genzyme Tissue Repair Designated Shares
reserved by the Genzyme Board as of such date for sale not later than six months
after such date, the proceeds of which sale will be allocated to the General
Division.

          UNCERTAINTY REGARDING PATENTS AND PROTECTION OF PROPRIETARY
TECHNOLOGY. Genzyme's success depends, to a large extent, on its ability to
maintain a competitive technological position in its product areas. Proprietary
rights relating to Genzyme's products are protected from unauthorized use by
third parties only to the extent that they are covered by 



                                       19
<PAGE>   20

patents or are maintained in confidence as trade secrets. Genzyme has filed for
patents and has rights to numerous patents and patent applications worldwide.
While certain of Genzyme's patents have been allowed or issued, there can be no
assurance that any additional patents will be allowed or will issue or that, to
the extent issued, such patents will effectively protect the proprietary
technology of Genzyme. In addition, Genzyme Tissue Repair does not yet have
significant patent protection covering the methodologies used in providing the
CARTICEL(R) Service. Consequently, Genzyme Tissue Repair is unable to prevent a
competitor from developing the ability to grow cartilage cell cultures and from
offering a service that is similar or superior to the CARTICEL(R) Service.
Genzyme Tissue Repair's results of operations could be materially and adversely
affected if a competitor were to develop such know-how.

          Genzyme has also relied upon trade secrets, proprietary know-how and
continuing technological innovation to develop and maintain its competitive
position. There can be no assurance that others will not independently develop
such know-how or otherwise obtain access to Genzyme's technology. While
Genzyme's employees, consultants and corporate partners with access to
proprietary information are generally required to enter into confidentiality
agreements, there can be no assurance that these agreements will be honored.
Certain of Genzyme's consultants have developed portions of Genzyme's
proprietary technology at their respective universities or in governmental
laboratories. There can be no assurance that such universities or governmental
authorities will not assert rights to intellectual property arising out of
university or government based research conducted by such consultants.

          Parties not affiliated with Genzyme may hold pending or issued patents
relating to technology utilized by Genzyme in its products presently available
or under development. Genzyme may, depending on the final formulation of such
products, need to acquire licenses to, or contest the validity of, such patents
or any other similar patents that may be issued. The extent to which Genzyme may
need to license such rights or contest the validity of such patents depends on
the scope and validity of such patents and ultimately on the final design or
formulation of its products under development. The cost and ability to license
any such rights and the likelihood of successfully contesting the validity of
such patents are uncertain.

          UNCERTAINTY REGARDING SUCCESS OF CLINICAL TRIALS. Several of Genzyme's
products are currently in clinical trials to test safety and efficacy in humans
for various conditions. There can be no assurance that Genzyme will not
encounter problems in clinical trials that will cause it to delay or suspend
clinical trials. In addition, there can be no assurance that such clinical
testing, if completed, will ultimately show these products to be safe and
efficacious.

          REGULATION BY GOVERNMENT AGENCIES. Most of the products Genzyme plans
to manufacture and sell will require approval by governmental agencies in the
United States and elsewhere. In particular, human therapeutic and diagnostic
products are subject to pre-marketing approval by the FDA and comparable
agencies in foreign countries. The process of obtaining these approvals varies
according to the nature and use of the product and can involve lengthy and
detailed laboratory and clinical testing, sampling activities and other costly
and time-consuming procedures. There can be no assurance that any of the
required approvals will be granted on a timely basis, if at all.

          Certain of Genzyme's products, including Ceredase(R) enzyme and
Cerezyme(R) enzyme, have been designated as orphan drugs under the Orphan Drug
Act, which provides incentives to manufacturers to develop and market drugs for
rare diseases. The Orphan Drug Act generally entitles the first developer to
receive FDA marketing approval for an orphan drug to a seven-year exclusive
marketing period in the United States for that product. Legislation has been
periodically introduced in recent years, however, to amend the Orphan Drug Act.
Such legislation has generally been directed to shortening the period of
automatic market exclusivity and granting certain marketing rights to
simultaneous developers of a drug. The effect on Genzyme of any amendments
ultimately adopted cannot be assessed at this time.

          A federal criminal statute prohibits the transfer of any human organ
for valuable consideration for use in human transplantation but permits recovery
of reasonable costs associated with such activities. To date, this statute has
not been applied to the CARTICEL(R) Service or the EpicelSM Service. In
addition, certain states have laws requiring the licensure of tissue and organ
banks and laws governing the sale of human organs and the safety and efficacy of
drugs, devices and biologics, including skin, all of which could be interpreted
to apply to Genzyme Tissue Repair's production and distribution of cultured
tissue products. Provisions in certain states' statutes prohibit the receipt of
valuable consideration in connection with the sale of human tissue by a tissue
bank but permit licensed tissue banks, including companies, to recover their
reasonable costs associated with such sales.

          RISKS INHERENT IN INTERNATIONAL OPERATIONS. Foreign operations of
Genzyme accounted for 35% of net sales in 1996 and 1995, compared to 31% in
1994. Financial results of Genzyme could be adversely or beneficially affected
by fluctuations in foreign exchange rates. Fluctuations in the value of foreign
currencies affect the dollar value of Genzyme's net investment in foreign
subsidiaries, with related effects included in a separate component of
stockholders' equity. Operating results of foreign subsidiaries are translated
into U.S. dollars at average monthly exchange rates. In addition, the U.S.
dollar value of transactions based in foreign currency (collections on foreign
sales or payments for foreign purchases) also fluctuates with exchange rates.
The largest foreign currency exposure results from activity in British pounds,
French francs, Swiss francs, Dutch guilders, German marks, Japanese yen, Spanish
pesetas and Italian lire.

          Genzyme attempts to manage this exposure by entering into forward
contracts with banks to the extent that the timing of currency flows can
reasonably be anticipated and by offsetting matching foreign currency
denominated assets with foreign currency denominated liabilities. Although to
date Genzyme has not hedged net foreign investments, the Company may engage in
hedging transactions to manage and reduce the Company's foreign exchange risk,
subject to certain restrictions imposed by the Genzyme Board, including that any
such transaction will be effected or disposed of on a securities exchange or
board of trade regulated under the laws of the United States, or with a
counterparty approved in accordance with certain financial strength criteria,
will be liquidated promptly after the purpose for which it is being maintained
is no longer applicable and will not be effected or maintained for the purpose
of speculation. There can be no assurance that Genzyme's attempts to manage its
foreign currency exchange risk will be successful.

          THIRD PARTY REIMBURSEMENT AND HEALTH CARE COST CONTAINMENT
INITIATIVES. A majority of Genzyme's revenues are attributable directly or
indirectly to payments received from third party payers, including government
health administration authorities and private health insurers. Significant
uncertainty exists as to the reimbursement status of newly approved health care
products, and third party payers are increasingly challenging the prices charged
for medical products and services. Third party payers are also increasingly
attempting to contain health care costs by limiting both coverage and the level
of reimbursement for new therapeutic products and by refusing in some cases to
provide coverage for uses of approved products for disease indications for which
the FDA has not granted marketing approval. There can be no assurance that any
third party insurance coverage will be available for any products or services
developed by Genzyme. If adequate coverage and reimbursement levels are not
provided by government and other third party payers for Genzyme's products and
services, the market acceptance of these products may be reduced and,
accordingly, Genzyme's revenues and profitability may be adversely affected.

          In addition, Congress has from time to time discussed the possible
implementation of broad based health care cost containment measures. While these
discussions have not led to the enactment of any specific health care cost
containment legislation, it is likely that health care measures will again be
proposed in Congress. The effects on Genzyme of any such measures that are
ultimately adopted cannot be measured at this time.

          PRODUCT LIABILITY AND LIMITATIONS OF INSURANCE. Genzyme may be subject
to product liability claims in connection with the use or misuse of its products
during testing or after commercialization. While Genzyme has taken, and
continues to take, what it believes are appropriate precautions, there can be no
assurance that Genzyme will avoid significant liability exposure. Genzyme has
only limited amounts of product liability insurance and there can be no
assurance that such insurance will provide sufficient coverage against any or
all potential product liability claims. If Genzyme attempts to obtain additional
insurance in the future, there can be no assurance that it will be able to do so
on acceptable terms, if at all, or that such insurance will provide adequate
coverage against claims asserted.

          POSSIBLE VOLATILITY OF SHARE PRICE AND ABSENCE OF DIVIDENDS. The
market prices for securities of biotechnology companies have been volatile.
Factors such as announcements of technological innovations or new commercial
products by Genzyme or its competitors, governmental regulation, patent or
proprietary rights developments, public concern as to the safety or other
implications of biotechnology products and market conditions in general may have
a significant impact on the market price of each series of Genzyme common stock.
No cash dividends have been paid to date on Genzyme common stock, nor does
Genzyme anticipate paying cash dividends on such stock in the foreseeable
future.

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Retirement Savings Plan Committee of the Genzyme Corporation Retirement
Savings Plan:

We have audited the accompanying statements of net assets available for plan
benefits of the Genzyme Corporation Retirement Savings Plan as of December 31,
1996 and 1995 and the related statement of changes in net assets available for
plan benefits, with fund information for the year ended December 31, 1996. We
previously audited and reported on the statement of changes in net assets
available for plan benefits, with fund information for the year ended December
31, 1995, which condensed statement is presented for comparative purposes. These
financial statements are the responsibility of the Plan Administrator. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits 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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for plan benefits of the Genzyme
Corporation Retirement Savings Plan as of December 31, 1996 and 1995, and the
changes in its net assets available for plan benefits for the year ended
December 31, 1996, in conformity with generally accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules listed in the
index on page 4 are presented for purposes of additional analysis and are not a
required part of the basic financial statements, but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. The fund information in the statement of changes in net assets available
for plan benefits is presented for purposes of additional analysis rather than
to present the changes in net assets available for plan benefits of each fund.
The supplemental schedule and fund information have been subjected to the
auditing procedures applied in the audits of the basic financial statements and,
in our opinion, are fairly stated in all material respects in relation to the
basic financial statements taken as a whole.

   
The schedule of reportable transactions that accompany the Plan's financial
statements do not disclose the historical cost of certain plan assets held by
the plan trustee. Disclosure of this information is required by the Department
of Labor's Rules and Regulations for Reporting and Disclosure under the
Employee Retirement Income Security Act of 1974.

                          NOTES TO FINANCIAL STATEMENTS

A.   PLAN DESCRIPTION:

     The following description of the Genzyme Corporation Retirement Savings
     Plan (the "Plan") provides only general information. Participants should
     refer to the plan agreement for a more complete description of the Plan's
     provisions.

     GENERAL

   
     The Plan, a defined contribution plan pursuant to the authorization of the
     Board of Directors of Genzyme Corporation ("Genzyme" or the "Company"), was
     established effective January 1, 1988 to provide a long-range program of
     systematic savings for eligible employees ("Participants"). Employees of
     all Genzyme's wholly-owned United States subsidiaries are eligible to
     participate in the Plan, with the exception of Deknatel Snowden Pencer,
     Inc. ("DSP"), an entity acquired by Genzyme during 1996, which has its own
     retirement plans that are still active. The Company expects to integrate
     the DSP plans into the Plan during 1997. As of December 31, 1996, all
     consolidated subsidiaries of Genzyme Corporation were 100% owned by the
     Corporation therefore making the Plan a plan for a controlled group of
     corporations. Employees who are 21 years of age or older become eligible to
     participate on their first day of employment. The Plan is subject to the
     provisions of the Employee Retirement Income Security Act of 1974

     $9,500 of their compensation contributed on a pre-tax basis to the Plan

     Eligible Participants may invest their contributions in any fund or funds
     in increments determined at their own discretion. Employer contributions
     are invested as directed by the Participants. If a Participant does not
     provide direction with respect to the investment of the Participant's
     contribution, all contributions will automatically be invested in the
     American Express Trust Income Fund.

     VESTING

     Participants have a 100% non-forfeitable interest in both employee and
     employer contributions at all times. Upon termination of employment or
     total and permanent disability, a Participant, or a Participant's
     beneficiary in the case of the Participant's death, is entitled to receive
     the full amount in the Participant's account.

     BENEFITS

     Distributions upon retirement at age 65 or later, or death, are either made
     in a lump-sum payment or installments. If the benefits are distributed in
     installments, the installments may not extend over a period of time longer
     than the life expectancy of the Participant or, if longer, the joint and
     last survivor life expectancy of the Participant and designated
     beneficiary. Distributions upon termination are made in lump-sum payments.

     Changes in allocation of future investments and reallocation of account
     balances among investment funds are permitted as of the last day of each
     quarter of the Plan year. Contributions may be withdrawn from the Plan only
     upon a demonstration of hardship, as defined, unless the Participant
     requesting such withdrawal has attained age 59 1/2. New employees with
     funds held under a previous employer's qualified plan are permitted to
     invest such funds into the Plan. These investments are classified as
     "rollovers."

     LOANS

     Participants may obtain a loan from the Plan collateralized by the
     Participant's vested interest in the Plan. No loan may exceed the lesser of
     one half of the vested interest of a Participant, or $50,000; and must be
     at least $1,000. A Participant may not obtain a loan unless the Plan
     Administrator approves the transaction. All loans bear interest determined
     by the Plan Administrator at the time of the loan. At December 31, 1996,
     the loans bear interest rates between 6% and 9% and mature through June
     2016. A written repayment schedule specifies the date and payment amount
     necessary to amortize the loan.



B.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     CASH EQUIVALENTS

     The Plan considers cash equivalents to be short-term, highly liquid
     investments, with initial maturities of less than three months.

     INVESTMENT VALUATION AND INCOME RECOGNITION

     Investments in the Fidelity Investment Grade Bond Fund, Fidelity Low Priced
     Stock Fund, Fidelity Magellan Fund, Fidelity Puritan Fund, Genzyme General
     Division Stock Fund and the Genzyme Tissue Repair Division Stock Fund are
     stated at market value, based on quoted market prices in an active market
     on the last business day of the plan


                                       7

     year. The American Express Trust Income Fund investments are stated at net
     asset value prices as reported by the American Express Trust Company
     Collective Investment Fund. Participant loans are valued at cost which
     approximates fair value.

     The Plan presents in the statement of changes in net assets available for
     plan benefits the net appreciation (depreciation) in the fair value of its
     investments which consists of the realized gains or losses and the
     unrealized appreciation (depreciation) on those investments. Security
     transactions are accounted for on the trade date. Gain or loss on sales of
     investments is based on average cost.

     INVESTMENT INCOME

     Dividend and interest income are recorded as of the payable date. Interest
     income is recorded as earned on the accrual basis.

     CONTRIBUTIONS AND BENEFIT PAYMENTS

     Employee contributions and matching employer contributions are recorded in
     the period the payroll deductions are made. Benefits are recorded when
     paid.

     USE OF ESTIMATES

     The preparation of the plan's financial statements in conformity with
     generally accepted accounting principles requires the plan administrator to
     make significant estimates and assumptions that affect the reported amounts
     of net assets available for benefits at the date of the financial
     statements and the changes in net assets available for benefits during the
     reporting period and, when applicable, disclosures of contingent assets and
     liabilities at the date of the financial statements. Actual results could
     differ from those estimates.

     RISKS AND UNCERTAINTIES

     The plan provides for various investment options in any combination of
     stocks, bonds, fixed income securities, mutual funds, and other investment
     securities. Investment securities are exposed to various risks, such as
     interest rate, market, and credit risks. Due to the level of risk
     associated with certain investment securities, it is at least reasonably
     possible that changes in the values of investment securities will occur in
     the near term and that such changes could materially affect participants'
     account balances and the amounts reported in the statement of net assets
     available for plan benefits.

C.   ADMINISTRATION FEES

     Administration fees associated with the Plan are paid by Genzyme and were
     approximately $224,000 and $134,000 in 1996 and 1995, respectively.

D.   QUALIFICATION UNDER THE INTERNAL REVENUE CODE

     The Internal Revenue Service has determined and informed the Company by a
     letter dated May 25, 1995, that the Plan and related trust are designed in
     accordance with applicable sections of the Internal Revenue Code (IRC). The
     Plan has been amended since receiving the determination letter. However,
     the Plan administrator and the Plan's tax counsel believe that the Plan is
     designed and is currently being operated in compliance with the applicable
     requirements of the IRC.

E.   AMENDMENT OR TERMINATION

     Genzyme intends to continue the Plan indefinitely but reserves the right to
     terminate it at any time or amend it in any manner advisable. No amendment
     may adversely affect the nonforfeitable interests of Participants in their
     accounts or permit the use or diversion of any part of the Plan other than
     for the exclusive benefit of the Participants or their beneficiaries
     (subject to plan provisions permitting payment of fees an expenses). No
     merger, consolidation, or transfers of assets or liabilities of the Plan
     may reduce any Participant's interest accrued to the date of the merger,
     consolidation, or transfer. If Genzyme discontinues its contributions or if
     the Plan is fully or partially terminated, the affected Participants'
     rights to benefits will remain fully vested.

F.   SUBSEQUENT EVENTS

     Effective April 1, 1997, the Plan changed its administrator and trustee.

   
     The Plan changed the frequency of the Company match which is now deposited
     bi-weekly or semi-monthly based on regular pay, rather than on a quarterly
     basis.
    

     Two new investment options were added to the Plan. These consist of a fixed
     income fund (CIGNA Guaranteed Income Fund) and an international investment
     fund (Templeton Foreign Account). The Plan held no shares of these new
     investment options as of December 31, 1996. Additionally, certain
     investment options were replaced with new investment options, both the
     American Express Trust Income Fund and the Fidelity Investment Grade Bond
     Fund were replaced by the CIGNA Guaranteed Securities Separate Fund;


   
                                       8
    
<PAGE>   9
     the Fidelity Magellan Fund was replaced by the CIGNA Stock Market Index
     Fund. The Fidelity Low Priced Stock Fund was replaced with the PBHG Growth
     Fund; and the Fidelity Puritan Fund remains an investment option in the 
     Plan.
