                       GENZYME DEVELOPMENT PARTNERS, L.P.
               NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1999

1.  BASIS FOR PRESENTATION

     Genzyme Development Partners, L.P., a Delaware limited partnership, was
formed in September 1989. The Partnership develops, produces and derives income
from the sale of Sepra products. The Sepra products are based on hyaluronic acid
and are intended to be used to limit the incidence and severity of postoperative
adhesions. In August 1996, Genzyme received marketing approval from the FDA for
the Partnership's first product, Sepra Film(R) Bioresorbable Membrane, in the
U.S. on behalf of Genzyme Ventures II. Genzyme Ventures II is a joint venture
between the Partnership and Genzyme.

     Per partnership unit information is based on the number of partnership
units outstanding at the end of each period. The number of units outstanding has
not changed since the date of capitalization of the Partnership.

     These unaudited financial statements should be read in conjunction with the
Partnership's 1998 Annual Report on Form 10-K and the financial statements and
footnotes included therein. Certain information and footnote disclosures
normally included in financial statements prepared in accordance with generally
accepted accounting principles have been condensed or omitted pursuant to the
rules and regulations of the SEC.

     The financial statements for the three and nine months ended September 30,
1999 and 1998 are unaudited but include, in the opinion of the management of the
General Partner, all adjustments (consisting only of normally recurring
accruals) necessary for a fair presentation of the results for the periods
presented.

2.  DEVELOPMENT AGREEMENT

     The Development Agreement calls for Genzyme to develop the Sepra products
for the Partnership. The Partnership was required to reimburse Genzyme for all
direct costs, a reasonable allocation of indirect costs as they relate to the
development effort and a 10% management fee, up to the available Partnership
funds. A non-refundable retainer fee of $1.5 million was paid by the Partnership
to Genzyme when the Partnership commenced. The General Partner has the authority
to terminate the research program at any time if it is deemed to be unfeasible
or uneconomical. The General Partner is a wholly-owned subsidiary of Genzyme.
Genzyme has no obligation to fund the research and development programs beyond
the available Partnership funds but has done so since the available Partnership
funds were expended in the first quarter of 1994. Genzyme currently intends to
fund the programs through 1999 on a level consistent with previous years and the
1999 budget for the program.

3.  JOINT VENTURE AGREEMENT

     For financial accounting purposes, Genzyme consolidates 100% of the losses
of Genzyme Ventures II funded by its non-interest bearing loans or capital
contributions. The Partnership has not recognized losses from Genzyme Ventures
II for the three and nine months ended September 30, 1999 because its basis in
the joint venture was reduced to zero in 1998.

</TABLE>

  Royalty Revenue

     Under the terms of the Cross License Agreement with Genzyme, the
Partnership is currently entitled to receive a royalty equal to 6% of net
revenues recognized from European sales of the Sepra products to the extent
necessary to pay certain projected distributions to the partners in any year.
Royalty revenue recognized by the Partnership increased in both periods due to
increased European sales of the Sepra products by Genzyme. The General Partner
believes that the Partnership will continue to be eligible to receive such
royalties during 1999.

  Net Income

     The increase in net income in the three months ended September 30, 1999 was
the result of increased royalty revenue recognized by the Partnership. The
increase in net income in the nine months ended September 30, 1999 was the
result of increased royalty revenue and the absence of any loss allocation from
Genzyme Ventures II due to the reduction of the Partnership's basis in the joint
venture to zero during the second quarter of 1998.

FINANCIAL CONDITION

     As of September 30, 1999, the Partnership had $61,000 in cash and cash
equivalents, a decrease of $36,000 from December 31, 1998. The remaining cash
balance is reserved for general and administrative expenses. In the nine months
ended September 30, 1999, the Partnership received $180,000 of cash from Genzyme
for royalty payments and used $220,000 of cash to reimburse Genzyme for expenses
it paid on behalf of the Partnership.

     The Partnership's future profitability is entirely dependent upon sales of
the Sepra products by Genzyme Ventures II. Under the Amended and Restated Joint
Venture Agreement, Genzyme has agreed, during the term of the joint venture, to
make non-interest bearing loans to the joint venture to fund any working capital
deficiency of the joint venture and to make capital contributions to the extent
deemed necessary by the two venturers in connection with the business of the
joint venture.

                                        7
<PAGE>   9

     The General Partner believes that substantial additional funds will be
required to complete the development and clinical testing of the Sepra products.
Genzyme has funded the research and development program for the Sepra products
on an annual basis since the first quarter of 1994, when all the available funds
of the Partnership were substantially depleted. Genzyme is not obligated to fund
additional development of the Sepra products but currently intends to continue
such funding during 1999 at a level consistent with prior years and the 1999
budget for these programs. There is no guarantee that Genzyme will continue
funding the Partnership's programs. If Genzyme discontinues funding the
Partnership's programs and the Partnership is unable to obtain any additional
financing or raise additional funds, the Partnership may delay, scale back or
eliminate certain of its programs.

EURO -- THE NEW EUROPEAN CURRENCY

     On January 1, 1999, a number of European countries adopted the Euro as
their common legal currency. All of the Partnership's revenues to date have been
derived from Genzyme's European sales of the Sepra products. The conversion to
the Euro has had no material effect on Genzyme's:

     - competitive position;

     - computer systems;

     - ability to conduct its business;

     - material contracts;

     - derivatives and other financial instruments;

     - exchange rate risk; or

     - tax rate.

     The disclosure related to the Euro conversion set forth under the heading
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Euro -- the New European Currency" in the Partnership's 1998
Annual Report on Form 10-K is incorporated herein by reference.

YEAR 2000

     Many computer systems and other equipment with embedded chips or processors
experience problems handling dates beyond the year 1999. As a result, older
programs may experience operating difficulties that cause date-sensitive
transaction errors or failures unless they are modified or upgraded to
adequately address the problem. The potential impact of the Year 2000 problem
cannot be fully appreciated at this time.

     The Partnership relies upon Genzyme to provide general and administrative
and other services. Genzyme Ventures II relies upon Genzyme to perform
manufacturing, marketing and sales services. The services provided by Genzyme to
the Partnership and Genzyme Ventures II involve the use of Genzyme's computer
systems and equipment.

     Genzyme is conducting a Year 2000 compliance program intended to identify
and minimize its exposure to Year 2000 problems. The compliance program is a
coordinated effort being conducted by each of Genzyme's divisions, business
units and departments. Genzyme is using its own MIS personnel to conduct the
program; it has not used any independent verification or validation processes in
connection with the program. Genzyme's program involves four phases:

     - conducting an inventory of its Year 2000 issues;

     - prioritizing identified systems, programs and equipment based on
       materiality to Genzyme's operations;

     - assessing Year 2000 compliance; and

     - resolving Year 2000 issues through upgrades, replacements or repairs.

     Genzyme has conducted an inventory of its information technology and
non-information technology systems, programs and equipment. Systems, programs
and equipment were evaluated based on their

                                        8
<PAGE>   10

importance to Genzyme's business, risk of failure and time horizon to failure,
among other things, and placed in one of the following seven categories:

      (i) mission critical;

      (ii) mission important;

      (iii) process critical;

      (iv) process important;

      (v) process convenient;

      (vi) reporting; and

     (vii) other.

     Genzyme has completed the first three phases of the program for all of its
systems, programs and equipment and is currently in the fourth phase of the
compliance program. Genzyme has determined that its Year 2000 exposures are
primarily in the following areas:

     - information systems;

     - financial and administrative applications;

     - manufacturing applications and equipment; and

     - research and development support systems, programs and equipment.

Genzyme has resolved the Year 2000 issues for the systems, programs and
equipment that fall into categories (i) through (iv) above. Genzyme is also
developing contingency plans with respect to categories (i) through (iii). Its
contingency plans include purchasing extra raw materials, making appropriate
staffing arrangements and ordering extra fuel. Genzyme plans to resolve Year
2000 issues for systems, programs and equipment in category (v) by the end of
the fourth quarter of 1999, and for systems, programs and equipment in
categories (vi) and (vii) as time permits. To date, Genzyme has not deferred any
significant information technology projects as a result of its Year 2000
compliance efforts.

     Concurrently with the conduct of its internal compliance program, Genzyme
is also surveying third patties it considers critical to its business about
their Year 2000 readiness. These third parties include:

     - significant customers,

     - suppliers,

     - significant research or collaborative partners,

     - service providers and

     - distributors.

     Genzyme substantially completed the survey in the third quarter of 1999.
Genzyme sent surveys to over 1,900 businesses and received responses from
approximately 77% of the group. Importantly, Genzyme received responses from all
of its critical suppliers and distributors. Genzyme is attempting to mitigate
its risks with respect to such third parties' Year 2000 compliance. It has
identified alternative resources for Genzyme's essential operations and is in
the process of securing these resources. Genzyme is also stock-piling raw
materials and finished goods.

     Genzyme may incur significant costs in assessing, resolving and mitigating
Year 2000 compliance issues. Each of its departments, business units and
divisions incurs its own costs in connection with readiness efforts. Genzyme
does not separately track the internal costs of its Year 2000 compliance
efforts, so these costs are unknown. However, Genzyme estimates that to date it
has spent approximately $1.0 million in replacing, upgrading or repairing
systems, programs or equipment. Although the aggregate additional costs of its
Year 2000 program cannot be known at this time, Genzyme's management currently
expects that the additional costs will be less than $0.5 million. The actual
costs will depend on numerous factors, including the nature and amount of
remediation work to be performed and internal staff costs. Genzyme intends to
fund all of its Year 2000 compliance program costs through operations. The
Partnership does not believe that the costs of Genzyme's Year 2000 program will
have a material effect on the Partnership's results of operations or

                                        9
<PAGE>   11

financial condition. It should be noted that the estimates discussed above do
not include costs incurred in connection with systems, programs or equipment
that were replaced or upgraded in the normal course of business for which the
timing was not accelerated due to Year 2000 issues.

     Genzyme cannot guarantee that its Year 2000 issues will be resolved by the
end of 1999. If Genzyme fails to identify and resolve all significant Year 2000
issues in a timely manner, it could experience interruptions or failures of its
normal business activities or operations, which would have a material adverse
effect on the Partnership's business, results of operations and financial
condition. The Partnership's business, results of operations and financial
condition could also be materially adversely affected by the failure of third
parties that are significant to the Partnership's or Genzyme's business to be
Year 2000 compliant. Any interruptions or failures of Genzyme's normal business
activities or operations could result in:

     - delays in the distribution of finished goods or receipt of raw materials;

     - disruptions in manufacturing activities;

     - disruptions of clinical programs;

     - delays in product development activities; or

     - errors or delays in customer order or invoice processing.

Genzyme's compliance program is an ongoing process, and the estimated costs and
timetables discussed above are subject to change.
