international business company and a wholly-owned subsidiary of Genzyme

outstanding units (the "Units"), each consisting of one share of Callable
Common Stock, $1.00 par value per share, of Neozyme II Corporation (the
"Company"), a BVI international business company, and a Callable Warrant to

TO THE HOLDERS OF UNITS OF
NEOZYME II CORPORATION:
 
                                  INTRODUCTION
 
     Neozyme II Acquisition Corp. (the "Purchaser"), a British Virgin Islands
("BVI") international business company and a wholly owned subsidiary of Genzyme
Corporation ("Genzyme"), a Massachusetts corporation, hereby offers to purchase
all of the outstanding units (the "Units"), each consisting of one share (the
"Shares") of callable common stock, par value $1.00 per share (the "Callable
Common Stock"), of Neozyme II Corporation ("Neozyme II" or the "Company"), a BVI
international business company, and one callable warrant (the "Callable
Warrants") to purchase two shares of General Division common stock, par value
$.01 per share ("General Division Common Stock"), and 0.135 share of Tissue
Repair Division common stock, par value $.01 per share ("Tissue Repair Division
Common Stock"), of Genzyme, at a purchase price of $45.00 per Unit, net to the
seller in cash, without interest thereon (the "Offer Price"), upon the terms and
subject to the conditions set forth in this Offer to Purchase and in the related
Letter of Transmittal (which, together with any amendments or supplements hereto
or thereto, collectively constitute the "Offer").
 
     Tendering Holders will not be obligated to pay brokerage fees or
commissions or, except as otherwise provided in Instruction 6 of the Letter of
Transmittal, stock transfer taxes with respect to the purchase by the Purchaser
of Units pursuant to the Offer. The Purchaser will pay all fees and expenses of
Robertson, Stephens & Company LLC ("Robertson, Stephens & Company"), which is
acting as the Dealer Manager for the Offer (in such capacity, the "Dealer
Manager"), American Stock Transfer & Trust Company, which is acting as the
Depositary (the "Depositary"), and Corporate Investor Communications, Inc.,
which is acting as the Information Agent (the "Information Agent"), incurred in
connection with the Offer. See "SPECIAL FACTORS -- Section 9. Fees and Expenses"
and "THE TENDER OFFER -- Section 12. Fees and Expenses."
 
     THE BOARD OF DIRECTORS OF THE COMPANY, BASED UPON, AMONG OTHER THINGS, THE
UNANIMOUS RECOMMENDATION OF A SPECIAL COMMITTEE OF THE BOARD CONSISTING OF THE
DIRECTORS OF THE COMPANY WHO ARE NOT OFFICERS OR DIRECTORS OF GENZYME,
UNANIMOUSLY HAS DETERMINED THAT EACH OF THE OFFER AND THE SECOND STEP
TRANSACTION IS FAIR TO, AND IN THE BEST INTERESTS OF, THE HOLDERS, HAS APPROVED
THE OFFER AND THE SECOND STEP TRANSACTION AND RECOMMENDS THAT THE HOLDERS ACCEPT
THE OFFER AND TENDER THEIR UNITS PURSUANT TO THE OFFER.
 
     THE OFFER IS CONDITIONED ON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER AT LEAST A
MAJORITY OF THE UNITS OUTSTANDING (THE "MINIMUM CONDITION"). IF LESS THAN A
MAJORITY OF THE UNITS OUTSTANDING ARE VALIDLY TENDERED AND NOT WITHDRAWN PRIOR
TO THE EXPIRATION OF THE OFFER, THE PURCHASER MAY ELECT TO AMEND AND EXTEND THE
OFFER TO ELIMINATE THIS CONDITION. IN THAT EVENT, DURING THE PERIOD THAT THE
OFFER IS EXTENDED, THE COMPANY SHALL, IN ACCORDANCE WITH APPLICABLE LAWS AND THE
PURCHASE AGREEMENT, SOLICIT THE APPROVAL OF THE HOLDERS OF THE SHARES FOR THE
SECOND STEP TRANSACTION AS DESCRIBED BELOW. ALTERNATIVELY, THE PURCHASER MAY
ELECT TO TERMINATE THE OFFER AND, PROMPTLY THEREAFTER, REQUEST THAT THE COMPANY
SOLICIT THE APPROVAL OF THE HOLDERS OF THE SHARES FOR THE SECOND STEP
TRANSACTION. IF THE PURCHASER DOES NOT MAKE EITHER ELECTION, GENZYME, THE
PURCHASER OR THE COMPANY MAY TERMINATE THE PURCHASE AGREEMENT. SEE "THE TENDER
OFFER -- SECTION 9. CERTAIN CONDITIONS OF THE OFFER."
 
     The Offer is being made pursuant to a Purchase Agreement dated as of
September 20, 1996 (the "Purchase Agreement") among Genzyme, the Purchaser and
the Company. The Purchase Agreement
 
                                        3
<PAGE>   4
 
provides that, among other things, as soon as practicable after the purchase of
Units pursuant to, or in certain circumstances the termination of, the Offer,
and the satisfaction of the other conditions contained in the Purchase Agreement
and in accordance with the applicable provisions of the BVI International
Business Companies Ordinance, 1984 (the "BVI Law"), the Purchaser will cause a
transaction by which Genzyme will, directly or indirectly, acquire all of the
Shares included in the untendered Units (the "Second Step Transaction"). If the
Offer is consummated and 90% or more of the Units are tendered and accepted, the
Purchaser will either (i) effect a merger of the Company into the Purchaser or
(ii) cause the Company to redeem all Shares included in the untendered Units. If
the Offer is consummated but less than 90% of the Units are tendered and
accepted, or if, pursuant to the Purchase Agreement, the Offer is terminated or
amended and the requisite approval of the Company's shareholders for the Second
Step Transaction is obtained, then the Second Step Transaction will be effected
as a merger of a wholly owned subsidiary of the Purchaser with and into the
Company. Regardless of the form of the Second Step Transaction, the
consideration to be received as a result of the Second Step Transaction by
holders of Shares included in the untendered Units (other than Genzyme, the
Purchaser or the Company or any direct or indirect subsidiary of any of them and
Holders, if any, who shall have demanded and perfected their appraisal rights
under the applicable provisions of the BVI Law) will be $29.00 per Share in
cash, without interest. Any Callable Warrants included in the untendered Units
will remain outstanding following the Second Step Transaction. Genzyme does not
intend to list the Callable Warrants remaining outstanding after the Second Step
Transaction on any securities exchange or to make a market in the Callable
Warrants. As a result, no liquid market may develop for the Callable Warrants,
which may adversely affect their value. See "SPECIAL FACTORS -- Section 8.
Certain Effects of the Transaction."
 
     The Company has advised Genzyme that Hambrecht & Quist LLC ("Hambrecht &
Quist"), financial advisor to the Special Committee, has delivered to the
Special Committee and the Company's Board of Directors its written opinion dated
September 20, 1996 that, on the basis of and subject to the matters set forth
therein, the cash consideration to be received by the Holders in exchange for
Units pursuant to the Offer and in exchange for Shares in the Second Step
Transaction is fair to such Holders from a financial point of view (the "H&Q
Opinion"). The Company has delivered to the Purchaser a copy of the H&Q Opinion,
together with Hambrecht & Quist's written consent to the inclusion of or
reference to the H&Q Opinion in the Tender Offer Statement on Schedule 14D-1
(the "Schedule 14D-1") filed by Genzyme and the Purchaser with the Securities
and Exchange Commission (the "Commission") in connection with the Offer, the
Rule 13e-3 Transaction Statement on Schedule 13E-3 filed by Genzyme, the
Purchaser and the Company with the Commission and the Schedule 14D-9 filed by
the Company with the Commission in connection with the Offer (the "Schedule
14D-9"). A copy of the H&Q Opinion is attached hereto as Annex I. See "SPECIAL
FACTORS -- Section 4. Recommendation of the Company's Board of Directors;
Fairness of the Transaction."
 
     The Company has filed with the Commission the Schedule 14D-9, which is
being mailed to Holders concurrently herewith.
 
     The Company has advised the Purchaser that, as of September 20, 1996, there
were 2,415,000 Units outstanding and that there were no Units or Shares reserved
for issuance for any purpose. As of such date, neither Genzyme nor the Purchaser
owned any Units; however, Genzyme is deemed to beneficially own all of the
outstanding shares of Neozyme II Callable Common Stock as a result of an option
to purchase all of the outstanding Shares, which option may be exercised by
Genzyme at any time through December 31, 1996. See "SPECIAL FACTORS -- Section
2. Agreements and Relationships Between the Company and Genzyme." Based upon
2,415,000 Units outstanding as of September 20, 1996, 1,207,501 Units must be
tendered in order to satisfy the Minimum Condition. All of the directors and the
executive officers of Genzyme and the Company currently intend to tender to the
Purchaser pursuant to the Offer all of the Units being sought by the Purchaser
that they hold of record or beneficially. Units tendered by officers and
directors of Genzyme and the Company will be purchased by the Purchaser on the
same terms and conditions offered to all Holders.
 
     In order to effect the Second Step Transaction as promptly as possible
following completion, or under certain circumstances the termination, of the
Offer, the Board of Directors of the Company has authorized a Plan of Merger
relating to a merger of a wholly owned subsidiary of the Purchaser with and into
the Company
 
                                        4
<PAGE>   5
 
(the "Merger Plan") in accordance with the BVI Law and the Company's Memorandum
and Articles of Association. The consummation of the Second Step Transaction is
subject to the satisfaction or waiver of certain conditions, including the
approval and adoption of the Merger Plan by the requisite vote or consent of the
Holders, if required by the BVI Law. Under the BVI Law and the Company's
Memorandum and Articles of Association, if the Purchaser acquires at least a
majority of the outstanding Units, the Purchaser would have sufficient voting
power to approve the Merger Plan by written consent in lieu of a meeting of
Holders and without the vote or consent of any other Holder and consummate the
Second Step Transaction. In addition, under the BVI Law, if the Purchaser
acquires at least 90% of the outstanding Units, the Purchaser would have the
power to consummate a merger of the Company into the Purchaser, or require the
Company to redeem all of the Shares not held by the Purchaser, without a vote of
the Holders. In either event, the Purchaser intends to take all necessary and
appropriate action to cause the Second Step Transaction to become effective as
soon as reasonably practicable after the consummation, or under certain
circumstances the termination, of the Offer without a meeting of the Holders.
See "SPECIAL FACTORS -- Section 6. The Purchase Agreement; Appraisal Rights."

                                SPECIAL FACTORS
 
1.  ESTABLISHMENT AND HISTORY OF THE COMPANY
 
     The Company was formed in March 1992 to contract with Genzyme to conduct
research, development and clinical testing of biotherapeutic products
("Products") for the treatment of cystic fibrosis ("CF") by protein replacement
or gene therapy (the "Field"). In August 1993, the Field was expanded to include
the products involved in Genzyme's collaboration with North American Biological,
Inc. ("NABI"). The lead product of the NABI collaboration, known as
HyperGAM(TM)+CF, was an antibody-based product for the prevention and treatment
of bacterial infections in CF patients. Development of all products in the NABI
collaboration was discontinued in June 1996 following an interim analysis of
data from a Phase II clinical trial of HyperGAM(TM)+CF. See "SPECIAL
FACTORS -- Section 5. Reasons for the Transaction; Purpose and Structure of the
Transaction; Plans for the Company after the Transaction." As used herein, the
term "Field" refers to the Field as so expanded.
 
     In May 1992, the Company and Genzyme completed a public offering (the "Unit
Offering") of 2,415,000 units (the "Offered Units"), each Offered Unit
consisting of one Share, one Series N Warrant to purchase, prior to the
adjustment described in the next paragraph, one share of common stock, par value
$.01 per share, of Genzyme ("Genzyme Common Stock") and one Callable Warrant to
purchase, prior to the adjustment described in the next paragraph, one share of
Genzyme Common Stock, at a price to the public of $35.00 per Offered Unit. The
Company received all of the approximately $78 million in net proceeds from the
Unit Offering. In connection with the Unit Offering, the Company issued its
Series 1992 Note to Genzyme and entered into a Technology License Agreement,
Development Agreement, Purchase Option Agreement, Services Agreement and
Administrative Agreement with Genzyme. The terms of the Series 1992 Note and
such agreements are summarized below.
 
     The Series N Warrants began trading separately from the Offered Units on
August 4, 1992, resulting in the Offered Units becoming the Units, consisting of
the Callable Common Stock and the Callable Warrants. As a result of a subsequent
recapitalization and stock split by Genzyme, each Callable Warrant now
represents the right to purchase two shares of Genzyme General Division Common
Stock and 0.135 share of Genzyme Tissue Repair Division Common Stock. The Units
trade on the Nasdaq National Market (the "NNM") under the symbol NIIUF.
 
2.  AGREEMENTS AND RELATIONSHIPS BETWEEN THE COMPANY AND GENZYME
 
     TECHNOLOGY LICENSE AGREEMENT.  Under the Technology License Agreement,
Genzyme granted to Neozyme II a worldwide exclusive right and license to
manufacture and sell Products within the Field based on all patent and other
intellectual property rights owned, controlled or acquired by Genzyme during the
term of the Development Agreement and as to which Genzyme has the right to grant
sublicenses.
 
     Neozyme II paid Genzyme $5 million in consideration for Genzyme entering
into the Technology License Agreement and in recognition of Genzyme's expertise
and expenditures in developing the technology licensed to Neozyme II. Genzyme
agreed to use commercially reasonable efforts to secure such technology rights
as it deems reasonably necessary to conduct the research to be performed for
Neozyme II under the Development Agreement. Neozyme II is obligated to assume,
subject to its prior consent, any royalty or other obligations to third parties
undertaken by Genzyme in the primary license. The license is otherwise royalty
free.
 
     Also pursuant to the Technology License Agreement, Neozyme II granted to
Genzyme a royalty-free, fully paid, irrevocable, perpetual, worldwide, exclusive
right and license to engage in any and all uses of Improvements, except for
those that are within the Field. "Improvements" consist of technology
discovered, developed or otherwise acquired in the course of research conducted
by Genzyme for Neozyme II under the Development Agreement. Neozyme II has agreed
that it will not, without first obtaining the consent of Genzyme, sublicense,
disclose or otherwise transfer any rights in the technology licensed to it by
Genzyme, or in Improvements, to any third party before the expiration or
termination of the Purchase Option Agreement.
 
                                        6
<PAGE>   7
 
     Either party may terminate the Technology License Agreement under certain
circumstances including breach by the other party of the Technology License
Agreement or the Development Agreement that continues unremedied for 60 days. If
the Technology License Agreement is terminated, the parties are obligated to
negotiate commercially reasonable royalties or other compensation for certain
rights, depending on which party terminated the agreement.
 
     DEVELOPMENT AGREEMENT.  Under the Development Agreement, Neozyme II has
engaged Genzyme to perform all of its research, development and clinical testing
activities relating to the Products through December 31, 1996 unless terminated
earlier. Genzyme agreed to use commercially reasonable efforts to conduct these
activities pursuant to certain work plans and budgets prepared by Genzyme and
approved by Neozyme II.
 
     Neozyme II is obligated to reimburse Genzyme for all costs associated with
Genzyme's work under the Development Agreement up to an amount consisting of
substantially all of the net proceeds from the Unit Offering plus interest
accrued thereon, less the $5 million payment to Genzyme under the Technology
License Agreement, less funds for use by Neozyme II for general and
administrative expenses and less $1 million to be retained by Neozyme II for
working capital (in the aggregate, the "Available Funds"). Genzyme may engage
other parties to assist in the work performed for Neozyme II under the
Development Agreement, provided that amounts paid to non-affiliates of Genzyme
may not exceed $15 million unless otherwise approved by Neozyme II. As of August
31, 1996, Neozyme II had paid approximately $74.5 million to Genzyme under the
Development Agreement. Based upon the work plan and budget approved for 1996 by
the Neozyme II Board of Directors, Neozyme expects the Available Funds to be
substantially exhausted by December 31, 1996.
 
     The Development Agreement may be terminated by either party under certain
circumstances including breach by the other party of the Technology License
Agreement or the Development Agreement that continues unremedied for 60 days.
The Development Agreement also provides that it will terminate 90 days after the
Available Funds become exhausted unless Genzyme elects to continue commercially
reasonable efforts to continue research and development of the Products at its
expense. Genzyme is under no obligation to continue such research and
development. Genzyme may assign its rights and delegate its obligations only to
an affiliate of Genzyme, certain successors of Genzyme or certain parties that
acquire substantially all of the assets of Genzyme under certain circumstances.
Neozyme II may not assign its rights or delegate its obligations under the
Development Agreement.
 
     PURCHASE OPTION AGREEMENT.  The Shares are subject to a purchase option
agreement (the "Purchase Option Agreement") pursuant to which Genzyme may
purchase all (but not less than all) of the shares from the holders thereof at
any time through December 31, 1996, unless exercisability is accelerated upon
exhaustion of the Available Funds.
 
     The Purchase Option is exercisable until December 31, 1996, at an exercise
price per share that increases each month through December 31, 1996 to a maximum
of $117.00 per share. The Purchase Option Exercise Price may be paid in cash, in
shares of Genzyme stock, or in any combination thereof, at Genzyme's discretion.
As of the date of this Offer to Purchase, the exercise price per share of the
Purchase Option was $108.50.
 
     Termination of the Development Agreement or the Technology License
Agreement due to a material breach by one of the parties will cause the Purchase
Option to terminate 60 days thereafter in the case of a breach by Genzyme or 120
days thereafter in the case of a breach by Neozyme II.
 
     SERIES 1992 NOTE.  In 1992, Neozyme II issued a note in the principal
amount of $100,000 to Genzyme (the "Series 1992 Note"). The Series 1992 Note is
due on the day following the termination of the Purchase Option Agreement and
may not be prepaid. Pursuant to Neozyme II's Amended and Restated Memorandum of
Association and Amended and Restated Articles of Association, Neozyme II and its
shareholders are prohibited from taking any action or permitting any action to
be taken that is inconsistent with Genzyme's rights under the Purchase Option
Agreement. In addition, pursuant to the Company's Memorandum of Association,
while the Series 1992 Note is outstanding, Neozyme II may not issue additional
capital stock, borrow more than $1 million in the aggregate, declare or pay
dividends utilizing funds committed to be paid to
 
                                        7
<PAGE>   8
 
Genzyme under the Development Agreement, merge, liquidate or sell all or
substantially all of its assets without the approval of Genzyme.
 
     SERVICES AND ADMINISTRATIVE AGREEMENTS.  Pursuant to these agreements, a
subsidiary of Genzyme (Genzyme Limited) provides certain financial, legal and
administrative services to Neozyme II on a cost reimbursement basis, and Neozyme
II is required to provide a list of record holders of the Callable Common Stock
to Genzyme upon Genzyme's exercise of the Purchase Option.
 
OTHER RELATIONSHIPS
 
     Since the Company's inception, the sole executive officer of the Company
has been an employee of Genzyme. From March 1992 until January 1996, G. Jan van
Heek, a Senior Vice President of Genzyme, served as the Company's President and
Treasurer. In January 1996, Mr. van Heek resigned as President and Treasurer of
the Company, and Paul M. Edwards was appointed to these positions. Mr. Edwards
also serves as Vice President and General Manager -- UK Operations for Genzyme,
a position he has held since April 1993. Henri A. Termeer, the Chairman of the
Board of the Company, is the Chairman, President and Chief Executive Officer of
Genzyme. In addition, Mr. Termeer is a trustee of Hambrecht & Quist Healthcare
Investors and Hambrecht & Quist Life Sciences Investors. Hambrecht & Quist has
acted as the Special Committee's financial advisor in connection with the
offering. Gregory D. Phelps, a Director of the Company, is an Executive Vice
President of Genzyme. Robert J. Carpenter, a Director of the Company, also
serves as a Director of Genzyme.
 
     The Company does not have and has never had its own research and
development employees or facilities and, therefore, it is heavily dependent upon
the employees, facilities and other resources of Genzyme. Genzyme and the
Company have also engaged the same independent auditors and outside legal
counsel since the Company's inception. Any material adverse change in the
business or financial condition of Genzyme could have a material adverse effect
upon the Company.
 
     As of September 20, 1996, neither Genzyme nor the Purchaser owned any
Units; however, Genzyme is deemed to beneficially own all of the outstanding
Shares as a result of its option under the Purchase Option Agreement. See
Schedule I and II for information concerning the ownership of Callable Common
Stock by the directors and executive officers of Genzyme.
 
3.  BACKGROUND OF THE TRANSACTION
 
     Beginning in the spring of 1996, Genzyme began to consider potential
alternatives to its existing contractual relationship with the Company. In
connection with these internal discussions, the members of Genzyme's management
responsible for overseeing the research program in CF (the "CF Program")
undertook an overall assessment of the CF Program, including the various
approaches to the treatment of CF which have been explored, the then-current
status of each such approach, the scientific questions that remained to be
addressed before an effective treatment for CF could be achieved, Genzyme's
knowledge of competitive CF programs, the Company's intellectual property
portfolio and the status of the HyperGAM(TM)+CF clinical trial then being
conducted by NABI, including the significance of the interim analysis for the
trial expected to be received in June 1996. A management report summarizing this
overall CF Program assessment was presented to the Genzyme Board of Directors at
its annual meeting held on May 16, 1996, along with a preliminary analysis of
Genzyme's alternatives to the existing relationship with the Company. No actions
in respect of a transaction with the Company were authorized at the meeting.
 
     Following the May 16, 1996 meeting, Genzyme continued to explore internally
alternative transactions that could be effected with the Company. On June 13,
1996, David J. McLachlan, Chief Financial Officer of Genzyme, contacted Kennett
F. Burnes, a director of the Company who is neither an officer nor a director of
Genzyme. Mr. McLachlan advised Mr. Burnes that, with just over six months
remaining under the terms of the various agreements between the Genzyme and the
Company, Genzyme was considering alternatives to its existing relationship with
the Company and that, among the alternatives under discussion, Genzyme was
considering the possibility of making an acquisition proposal on terms different
from the Purchase Option or making a proposal to continue funding the CF
Program. Mr. McLachlan further advised that, while the
 
                                        8
<PAGE>   9
 
Genzyme Board of Directors had not approved any proposal concerning the Company,
Genzyme expected to have authorization from the Genzyme Board to make a proposal
to the Company's Board of Directors at the next regularly scheduled meeting of
the Company's Board to be held on July 23, 1996. Mr. McLachlan then suggested
that it would be appropriate for the Company's Board of Directors to consider
engaging independent advisors in connection with any possible transaction that
might occur with Genzyme.
 
     In response to Mr. McLachlan's call, Mr. Burnes contacted the investment
banking firm of Hambrecht & Quist and the law firm of Hale and Dorr to discuss
the possible engagement of these firms to advise the Company's Board of
Directors in any transaction with Genzyme.
 
     On June 20, 1996, NABI and Genzyme received the results of an interim
analysis for the clinical trial being conducted for HyperGAM(TM)+ CF from an
independent statistician. Although no major issues with the safety of the
product were identified, the data also showed no difference in efficacy between
those patients in the trial receiving placebo and those receiving either a high
or low dose of HyperGAM(TM)+ CF. On June 21, 1996, a special meeting of the
Company's Board of Directors was convened and a summary of the interim analysis
for the HyperGAM(TM)+ CF trial was presented to the Board. Following the
presentation, the Company's Board of Directors voted unanimously to terminate
the agreement with NABI and, later that day, the Company and NABI announced the
discontinuation of the trial. There were no discussions regarding the
relationship between Genzyme and the Company at this meeting of the Company's
Board of Directors.
 
     In light of the discontinuation of the HyperGAM(TM)+ CF trial, Genzyme
re-evaluated the alternatives under consideration with respect to the Company.
In connection with these efforts, in July 1996, Genzyme engaged Robertson,
Stephens & Company to provide financial advisory services to Genzyme in
connection with a possible acquisition of the Company. In connection with its
engagement, Robertson, Stephens & Company conducted a due diligence review of
the Company.
 
     On July 18, 1996, at a regularly scheduled meeting of the Genzyme Board of
Directors, Genzyme management presented an analysis of Genzyme's options
regarding the Company, and recommended that Genzyme make an offer to acquire the
outstanding Units. Representatives of Robertson, Stephens & Company then made a
preliminary presentation to the Genzyme Board of Directors. Following the
presentations, the Genzyme Board of Directors voted to authorize management to
initiate discussions regarding the acquisition of the Company with the
independent directors of the Company and, if and when management determined that
an offer would be in the best interest of Genzyme, to make an offer to acquire
the outstanding Units at a price of up to $40 per Unit in cash.
 
     After such meeting, Mr. McLachlan called Mr. Burnes to advise him that
Genzyme was considering the possibility of presenting an acquisition proposal to
the Company's Board of Directors at the meeting scheduled for July 23, 1996.
Following this call, on July 22, 1996 at the request of Mr. Burnes, Dennis J.
Purcell, a Managing Director of Hambrecht & Quist, called Peter Wirth, Genzyme's
General Counsel, to discuss the agenda for the upcoming meeting of the Company's
Board of Directors. Mr. Wirth indicated that, as originally scheduled, the
purpose of the meeting was to provide the Company's Board of Directors with an
update as to the current status of the CF Program and that, as Mr. McLachlan had
related to Mr. Burnes, Genzyme was also considering the possibility of
presenting an acquisition proposal to the Company's Board. In response, Mr.
Purcell suggested that while it was important for Genzyme to provide the
Company's Board of Directors with an update as to the current status of the CF
Program, significant additional due diligence would be required before the
Company's Board would be in a position to respond to any acquisition proposal
Genzyme might make. In response to Mr. Purcell's comments, it was agreed that
the topics of discussion for the next day's meeting would be directed primarily
towards the CF Program update and the process that might be followed in
considering an acquisition proposal from Genzyme once the Company was prepared
to respond to such a proposal.
 
     On July 23, 1996, a meeting of the Company's Board of Directors was
convened. In addition to the members of the Board, representatives of Genzyme's
management and Mr. Purcell were present. At the meeting, an update of the report
summarizing the overall CF Program assessment previously presented to the
Genzyme Board of Directors was presented to the Company's Board of Directors.
Following the report, Mr. Wirth advised the Company's Board of Directors that,
in view of the current status of the CF Program,
 
                                        9
<PAGE>   10
 
Genzyme did not expect to exercise the Purchase Option and that, in lieu of the
Purchase Option, Genzyme's management was considering the possibility of making
an acquisition proposal with respect to the Company. Mr. Wirth then described in
general terms the process that might be followed by the Company's Board of
Directors in considering an acquisition proposal from Genzyme and suggested that
the Company's Board appoint a special committee of directors to consider any
such proposal that Genzyme might determine to make.
 
     In response to Mr. Wirth's comments, the Company's Board of Directors
appointed the Special Committee consisting of Mr. Burnes and Robert E. Flynn,
the two directors of the Company who are not officers or directors of Genzyme,
to consider any acquisition proposal which might be made by Genzyme. The members
of the Special Committee and Mr. Purcell then requested that management provide
a list of experts in the CF field who might be retained to perform an
independent technical evaluation of the CF Program. It was further requested
that management make available members of the CF Program staff for purposes of
conducting due diligence. On July 25, 1996, Hambrecht & Quist selected Melissa
Rosenfeld, M.D., a leading scientist in the CF field, as its technical
consultant.
 
     On August 2, 1996, representatives of Hambrecht & Quist and Hale and Dorr
and Dr. Rosenfeld met with representatives of management to conduct a due
diligence review of the Company and the CF Program.
 
     Following such due diligence session, Hambrecht & Quist had discussions
with Robertson Stephens & Company and Hale and Dorr had discussions with Palmer
& Dodge, Genzyme's outside law firm, concerning the timing and process of the
due diligence review and a response to any acquisition proposal Genzyme might
make. Mr. Burnes and Mr. McLachlan also discussed the status of the Special
Committee's efforts by telephone.
 
     On August 7, 1996, a meeting of the Special Committee was held to review
the status of due diligence efforts and discussions with Genzyme regarding a
potential acquisition proposal. Representatives of Hambrecht & Quist and Hale
and Dorr participated in the meeting. The Special Committee approved and
ratified the engagement of Hambrecht & Quist as financial advisor, Hale and Dorr
as legal counsel and Dr. Rosenfeld as technical consultant.
 
     On August 8, 1996, a conference call between representatives of Genzyme,
representatives of Hambrecht & Quist and Mr. Burnes was held. During the call,
Mr. Wirth stated that Genzyme's management was considering making a proposal to
acquire all of the outstanding Units for cash at a price per Unit equal to a
discount of 10% to 15% from the then-current market price of the Units. Messrs.
Wirth and McLachlan explained further that Genzyme believed a below-market price
was justified in view of the current status of the CF Program, including the
failure of HyperGAM(TM)+CF, the largely inactive status of the protein
replacement program and the uncertainty surrounding gene therapy. In response to
questions from representatives of Hambrecht & Quist regarding alternatives to a
cash transaction, Mr. McLachlan advised that Genzyme had rejected the use of
Genzyme stock, warrants or contingent value rights due to concerns over dilution
and because it believed that the use of contingent rights would make the
transaction more difficult for investors to value. In response to the comments
from Messrs. Wirth and McLachlan, Messrs. Purcell and Burnes stated that the
Special Committee would be unlikely to accept any offer at a price below market,
but noted that Hambrecht & Quist had not yet concluded its analyses and,
therefore, it was premature to commence negotiations regarding an acquisition
price.
 
     Over the next weeks, Hambrecht & Quist and Hale and Dorr continued to
conduct additional due diligence with respect to the Company. In particular,
Hambrecht & Quist requested, received and reviewed documents from Genzyme
relating to the Company, including general corporate materials, financial and
accounting information, financial projections, license agreements and
collaborations with third parties, copies of reports made to the Board of
Directors concerning progress of the Company's research and development programs
and analysts' reports on the Company, its competitors and CF in general. In
addition, representatives of Hambrecht & Quist began to make informal inquiries
as to the possible interest of potential third party purchasers of the Company.
Hale and Dorr reviewed the existing agreements between the Company and Genzyme
as well as the Company's patent position. Dr. Rosenfeld also continued to
conduct additional due
 
                                       10
<PAGE>   11
 
diligence with respect to the Company and the CF Program and provided an
assessment of the CF Program to Hambrecht & Quist.
 
     At a meeting of the Special Committee held on August 22, 1996, Hambrecht &
Quist reported on the status of its due diligence review, indicating that, with
the assistance of Dr. Rosenfeld, progress had been made on assessing the
Company's technology. Hambrecht & Quist also indicated that it had made some
informal inquiries as to the possible interest of potential third party
purchasers, and determined that interest in the Company appeared to be
insignificant due, among other things, to the limited nature of the Company's
technology rights. Hale and Dorr provided an assessment of the Company's patent
portfolio. It was also reported that the Company had agreed to indemnify the
members of the Special Committee against liabilities arising out of their
service on the Special Committee.
 
     On September 3, 1996, Messrs. McLachlan and Wirth met with David G. Golden,
a Managing Director of Hambrecht & Quist, and Mr. Purcell to discuss the
proposed acquisition price. Messrs. McLachlan and Wirth reiterated Genzyme's
position that an acquisition price per Unit equal to a discount of 10% to 15%
from the then current market price of the Units was appropriate in view of the
status of the CF Program. Hambrecht & Quist stated that it did not believe the
Special Committee would accept an acquisition price below market and that
Genzyme should expect to have to pay a premium over the then-current market
price of the Units. On September 4, 1996 Mr. McLachlan and Mr. Burnes discussed
the previous day's telephone conference. Mr. Burnes reiterated that the Special
Committee believed that any offer should be above the then current market price.
 
     On the morning of September 5, 1996, the Genzyme Board of Directors
authorized management to propose an acquisition at $45 per Unit in cash if
Genzyme's management could reach an agreement with the Special Committee at such
price and if the Special Committee would recommend such price to the Holders.
Mr. Termeer contacted Mr. Burnes and indicated that Genzyme's management would
be willing to recommend to Genzyme's Board of Directors an increased acquisition
price of $45 per Unit in cash, if the Special Committee would recommend such
price to the Holders (the "Genzyme Proposal"). Mr. Burnes agreed to review the
Genzyme Proposal with Mr. Flynn and Hambrecht & Quist.
 
     In the evening of September 5, 1996, the Special Committee met to consider
the Genzyme Proposal. Hambrecht & Quist presented its preliminary analysis of
the fairness of the Genzyme Proposal to the holders of the Units from a
financial point of view and expressed its preliminary opinion that the Genzyme
Proposal was fair to the holders of the Units from a financial point of view.
Hambrecht & Quist noted that its opinion was subject to negotiation and review
of the documentation for the transaction and satisfactory resolution of the
structure of the transaction with respect to those Holders who do not tender
their Units pursuant to the Offer. After review of the foregoing analysis and
other considerations, the Special Committee unanimously approved in principle a
transaction in which Units of the Company would be purchased by Genzyme at a
purchase price of $45 per Unit in cash, subject to (a) negotiation and execution
of definitive agreements, (b) receipt of Hambrecht & Quist's written fairness
opinion, and (c) satisfactory resolution of the structure of the transaction
with respect to non-tendering shareholders.
 
     On September 6, 1996, the Company and Genzyme jointly announced that they
had reached an agreement in principle relating to the acquisition of the Company
for $45 per Unit, subject to negotiation and execution of a definitive
acquisition agreement.
 
     During the next two weeks, drafts of the Purchase Agreement were exchanged
between Genzyme and the Company and their respective legal and financial
advisors and the terms of such agreement were negotiated, including the
structure of the Second Step Transaction, the amount of consideration to be paid
in connection with the Second Step Transaction and arrangements between the
parties in the event of a superior transaction, including the payment of a
termination fee to Genzyme upon the consummation of a superior transaction and
Genzyme's agreement to consent to the early assignment of the Technology License
Agreement in connection with a superior transaction.
 
     On September 10, 1996, the Special Committee met with its financial and
legal advisors to review issues relating to the draft Purchase Agreement.
Hambrecht & Quist reported that several of the Company's
 
                                       11
<PAGE>   12
 
shareholders had contacted it with respect to the Offer, and indicated that
shareholders had expressed dissatisfaction with the $45 price per Unit,
principally due to their perception that Genzyme had previously led them to
believe that any repurchase of the Units would be at a higher price.
 
     On September 17, 1996, the Genzyme Board of Directors held a special
meeting to assess the status of the proposed transaction. At such meeting,
Robertson, Stephens & Company made a presentation to the Genzyme Board (the
"Robertson, Stephens & Company Presentation"). The Genzyme Board then reviewed
with management the status of negotiations concerning the Purchase Agreement.
 
     On September 20, 1996, the Special Committee met with its financial and
legal advisors to consider the Purchase Agreement. As described more fully below
under "SPECIAL FACTORS -- Section 4. Recommendation of the Company's Board of
Directors; Fairness of the Transaction", the Special Committee unanimously
recommended that Neozyme II's Board of Directors approve the Offer and the
Second Step Transaction. Thereafter, the full Neozyme II Board of Directors met
and, upon the receiving the recommendation the Special Committee, unanimously
determined (i) to accept the recommendation of the Special Committee, (ii) based
upon, among other considerations, the recommendation of the Special Committee
that the Offer and the Second Step Transaction are fair to, and in the best
interests of, holders of the Units and (iii) to approve the Purchase Agreement
and the transactions contemplated thereby.
 
     Following the meeting of the Company's Board of Directors on September 20,
1996, the Genzyme Board of Directors held a special meeting. At such meeting,
Robertson, Stephens & Company delivered to the Genzyme Board its written
opinion, dated September 20, 1996 (the "Robertson, Stephens & Company Opinion"),
that, as of such date, and based upon and subject to the factors and assumptions
set forth in such opinion, the Offer Price was fair to Genzyme from a financial
point of view. After discussion with respect to the Offer and the other terms
and conditions of and transactions contemplated by the Purchase Agreement and
considering the matters discussed under "SPECIAL FACTORS -- Section 4.
Recommendation of the Company's Board of Directors; Fairness of the Transaction"
and "-- Section 5. Reasons for the Transaction; Purpose and Structure of the
Transaction; Plans for the Company after the Transaction" and the Robertson,
Stephens & Company Opinion, the Genzyme Board unanimously determined (i) to
approve the Offer and the Second Step Transaction, the Purchase Agreement and
the transactions contemplated thereby and (ii) that, based upon, among other
things, the conclusion of the Special Committee and the Company's Board, the
terms of the Offer and the Second Step Transaction are fair to unaffiliated
holders of the Units.
 
     The Purchase Agreement was executed by the parties and on September 23,
1996 a press release announcing the execution of the Purchase Agreement was
issued.
 
     On September 27, 1996, the Purchaser commenced the Offer.
 
4.  RECOMMENDATION OF THE COMPANY'S BOARD OF DIRECTORS; FAIRNESS OF THE
TRANSACTION
 
     At a meeting held on September 20, 1996, the Special Committee unanimously
determined that the Offer and the Second Step Transaction are fair to, and in
the best interests of, the Holders and resolved to recommend that the Board (a)
determine that the Offer and the Second Step Transaction are fair to, and in the
best interests of, the Holders; (b) adopt and approve the Offer, the Second Step
Transaction, the Purchase Agreement and the transactions contemplated thereby;
and (c) recommend that the Holders accept the Offer and tender their Units to
the Purchaser pursuant to the Offer.
 
     In determining that the Offer and the Second Step Transaction are fair to,
and in the best interests of, the Holders, and in making its recommendation to
the Board, the Special Committee considered the following factors, which, taken
as a whole, supported its decision:
 
          (a) the financial condition of the Company, including the fact that
     the Company's current cash is expected to be substantially exhausted by
     December 31, 1996 and the uncertain prospects of raising new capital in
     light of the current financing market for biotechnology companies,
     including the fact that many public offerings of biotechnology companies
     have either been postponed or priced below anticipated price ranges;
 
                                       12
<PAGE>   13
 
          (b) the status of the Company's technology programs (based, in part,
     on input previously provided to Hambrecht & Quist by Dr. Rosenfeld and a
     prior oral presentation concerning the patent position of the Company's
     technology by Hale and Dorr, the Committee's independent legal counsel),
     including the fact that the Company's protein replacement therapy program
     has been largely inactive since 1994 and the decision in June 1996 to halt
     clinical trials for HyperGAM(TM)+CF;
 
          (c) the prospects of the Company, including the fact that the
     Company's gene therapy programs are unlikely to yield commercially viable
     products within the CF field for at least several years;
 
          (d) the fact that the market value of the Units is currently
     significantly lower than the Purchase Option Exercise Price and, that given
     the current status of the Company's technology programs and its prospects,
     the likelihood that the per Unit trading price on the NNM will not reach
     the Purchase Option Exercise Price prior to the expiration of the Purchase
     Option Agreement on December 31, 1996;
 
          (e) the valuation analyses presented to the Special Committee by
     Hambrecht & Quist at its September 5, 1996 and September 20, 1996 meetings;
 
          (f) the H&Q Opinion stating that, on the basis of and subject to the
     matters set forth therein, the cash consideration to be received by the
     shareholders of the Company in exchange for the Units in the Offer and in
     exchange for the Shares in the Second Step Transaction are fair to the
     holders of the Units and the Shares from a financial point of view. The H&Q
     Opinion contains a description of the factors considered, the assumptions
     made and the scope of review undertaken by Hambrecht & Quist in rendering
     the H&Q Opinion and is included herein as Annex I and is incorporated
     herein by reference. SHAREHOLDERS ARE URGED TO READ THE H&Q OPINION
     CAREFULLY IN ITS ENTIRETY;
 
          (g) the judgment of the Special Committee that $45 per Unit is the
     highest price reasonably available to the Company's shareholders for the
     following reasons:
 
             (1) the course of negotiations between the parties regarding the
        offering price, including the fact that Genzyme's original indication of
        interest was at a price level approximately 10% to 15% below the then
        current trading price of the Units of $44 and the fact that the $45 per
        Unit price represented a premium over the $44 1/16 trading price of the
        Units on the day before an agreement in principle with Genzyme was
        announced;
 
             (2) the pursuit of alternate transactions with third parties was
        not deemed to be a viable alternative (based, in part, on input received
        by Hambrecht & Quist in response to informal inquiries as to the
        possible interest of potential third party purchasers) given the nature
        of the contractual arrangements between the Company and Genzyme and the
        fact that the Company's rights in the technology developed in the course
        of its research programs is limited to the Field; and
 
             (3) since September 6, 1996, when Genzyme and the Company publicly
        announced an agreement in principle on an acquisition at $45 per Unit in
        cash, no third party had expressed an interest in having discussions
        with the Company to Hambrecht & Quist, which was identified in the press
        release as the Company's contact, or the Special Committee; and
 
          (h) the terms and conditions of the Purchase Agreement, including the
     right of the Special Committee to terminate the Purchase Agreement in order
     to proceed with a Superior Transaction.
 
     The Special Committee also considered the following negative factors
relating to the Offer and the Second Step Transaction:
 
          (a) since the announcement of an agreement in principle with Genzyme,
     a number of the Company's shareholders contacted Hambrecht & Quist and the
     Special Committee and indicated they believe Genzyme should pay more than
     $45 per Unit, due, in part, to the indirect benefits Genzyme has received
     from the Company's technology programs; and
 
                                       13
<PAGE>   14
 
          (b) the upside potential if the Company's technology programs, which
     are well regarded in scientific circles, are ultimately successful in
     discovering one or more products useful in the treatment of CF.
 
     The members of the Special Committee evaluated the above factors in light
of their knowledge of the business of the Company and their business judgment
and concluded that the factors supporting a decision to approve the Purchase
Agreement outweighed the negative factors described above. In view of the wide
variety of factors considered in connection with its evaluation of the Offer and
the Second Step Transaction, the Special Committee did not find it practicable
to, and did not, quantify or attempt to assign relative weights to the specific
factors considered in reaching its decision.
 
     The Special Committee believes the process it followed in approving the
Offer and the Second Step Transaction was procedurally fair and unbiased because
(a) the Special Committee, consisting of all the directors of the Company who
are not directors or officers of Genzyme, was constituted to consider and
evaluate Genzyme's acquisition proposal with respect to the Company; (b) the
members of the Special Committee will not personally benefit from the
transactions contemplated by the Purchase Agreement (other than in their
capacity as holders of Units); (c) the Special Committee retained independent
advisors to assist it in evaluating Genzyme's acquisition proposal; (d) the
Special Committee obtained the valuation analysis of Hambrecht & Quist and the
H&Q Opinion; and (e) the Special Committee negotiated with Genzyme on an arm's
length basis and with the assistance of its advisors.
 
     On September 20, 1996, the Board held a meeting and, based upon, among
other things, the unanimous recommendation of the Special Committee (which was
adopted by the Board in all respects), determined that the Offer and the Second
Step Transaction are fair to, and in the best interests of, the Holders,
approved the Offer and the Second Step Transaction and resolved to recommend
that the Holders accept the Offer and tender their Units to the Purchaser
pursuant to the Offer.
 
OPINION OF FINANCIAL ADVISOR TO THE SPECIAL COMMITTEE
 
     The Special Committee engaged Hambrecht & Quist to act as its financial
advisor in connection with Genzyme's proposed acquisition of the Company and to
render an opinion as to the fairness from a financial point of view to (a) the
holders of Units of the consideration to be received by such holders in
connection with Genzyme's offer to purchase all of the outstanding Units at a
purchase price of $45.00 per Unit in cash, and (b) the holders of the Shares of
the consideration to be received by such holders in connection with the Second
Step Transaction pursuant to which, if the Offer is consummated, but not all of
the Units are tendered and accepted or, if the Offer is terminated in accordance
with the Purchase Agreement so that Genzyme may pursue a Termination
Solicitation, Genzyme will acquire, directly or indirectly, all of the remaining
Shares in exchange for cash in an amount equal to $29.00 per Share. Hambrecht &
Quist rendered its oral opinion (subsequently confirmed in writing) on September
20, 1996 to the Special Committee that, as of such date, the consideration to be
received by the holders of the Units pursuant to the Offer and the consideration
to be received by the holders of the Shares pursuant to the Second Step
Transaction is fair to such holders from a financial point of view. Hambrecht &
Quist also delivered its oral opinion (subsequently confirmed in writing) to the
Company's Board of Directors at its meeting on September 20, 1996. A COPY OF
HAMBRECHT & QUIST'S OPINION DATED SEPTEMBER 20, 1996, WHICH SETS FORTH THE
ASSUMPTIONS MADE, MATTERS CONSIDERED, THE SCOPE AND LIMITATIONS OF THE REVIEW
UNDERTAKEN AND THE PROCEDURES FOLLOWED BY HAMBRECHT & QUIST IS ATTACHED AS ANNEX
I TO THIS OFFER TO PURCHASE. NEOZYME II SHAREHOLDERS ARE ADVISED TO READ THE
OPINION IN ITS ENTIRETY. Hambrecht & Quist delivered to the Special Committee
written materials covering its methods of analyzing the Company and the Callable
Warrants and the financial results of such analyses in connection with its
September 20, 1996 opinion, which are attached as an exhibit to the Schedule
13E-3 filed with the Commission in connection with the Offer and will be
available for inspection and copying at the principal executive offices of
Genzyme during regular business hours by any interested shareholder of the
Company or a representative of such shareholder who has been so designated in
writing.
 
     No limitations were placed on Hambrecht & Quist by the Special Committee
with respect to the investigation made or the procedures followed in preparing
and rendering the H&Q Opinion. Hambrecht & Quist was not requested to and did
not make any recommendation to the Special Committee as to the amount of
consideration to
 
                                       14
<PAGE>   15
 
be offered to the Company's shareholders in the Offer and the Second Step
Transaction, which consideration was determined through negotiations between the
Special Committee and its financial and legal advisors and Genzyme and its
financial and legal advisors. Hambrecht & Quist was not requested to and did not
formally solicit third party indications of interest in acquiring all or any
part of the Company. Hambrecht & Quist did, however, make informal inquiries as
to the possible interest of potential third party purchasers, and determined
that interest in the Company appeared to be insignificant due, among other
things, to the limited nature of the Company's technology rights. Holders of
Units should note that the opinion expressed by Hambrecht & Quist was provided
for the information of the Special Committee and the Board of Directors of the
Company in its evaluation of the Offer and the Second Step Transaction and does
not constitute a recommendation to any shareholder as to how such shareholder
should act with respect to the Offer.
 
     In connection with its review of the proposed transaction with Genzyme, and
in arriving at its opinion, Hambrecht & Quist, among other things: (i) reviewed
the publicly available consolidated financial statements of the Company for
recent years and interim periods to date and certain other relevant financial
and operating data of the Company made available to Hambrecht & Quist from
published sources and from the internal records of the Company; (ii) discussed
with certain members of the managements of the Company and Genzyme the business,
financial condition and prospects of the Company; (iii) reviewed the publicly
available consolidated financial statements of Genzyme for recent years and
interim periods to date; (iv) reviewed certain internal financial and operating
information, including certain projections, relating to the Company prepared by
the management of Genzyme; (v) reviewed the recent reported prices and trading
activity for the Units and compared such information and certain financial
information of the Company with similar information for certain other companies
engaged in businesses Hambrecht & Quist considered comparable to that of the
Company; (vi) reviewed the financial terms, to the extent publicly available, of
certain comparable acquisition transactions; (vii) reviewed drafts of the
Purchase Agreement, the Offer Documents and certain other materials to be filed
with the Securities and Exchange Commission in connection with the Offer; and
(viii) performed such other analyses and examinations and considered such other
information, financial studies, analyses and investigations and financial,
economic and market data as Hambrecht & Quist deemed relevant.
 
     In rendering its opinion, Hambrecht & Quist assumed and relied upon the
accuracy and completeness of all of the information concerning the Company and
Genzyme considered in connection with its review of the proposed transaction,
and Hambrecht & Quist did not assume any responsibility for independent
verification of such information. Hambrecht & Quist did not prepare any
independent valuation or appraisal of any of the assets or liabilities of the
Company, nor did Hambrecht & Quist conduct a physical inspection of the
properties and facilities of the Company. With respect to the financial
forecasts and projections made available to Hambrecht & Quist and used in its
analysis, Hambrecht & Quist assumed that they reflected the best currently
available estimates and judgments of the expected future financial performance
of the Company. For purposes of its opinion, Hambrecht & Quist assumed that the
Company was not a party to any pending transactions, including external
financings, recapitalizations or material merger discussions, other than the
proposed transaction with Genzyme and those activities undertaken in the
ordinary course of conducting its business. Hambrecht & Quist's opinion was
necessarily based upon market, economic, financial and other conditions as they
existed and could be evaluated as of the date of their opinion and any change in
such conditions would require a reevaluation of that opinion.
 
     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. The summary
of the Hambrecht & Quist analyses set forth below does not purport to be a
complete description of the analyses underlying the H&Q Opinion. In arriving at
its opinion, Hambrecht & Quist did not attribute any particular weight to any
analysis or factor considered by it, but rather made qualitative judgments as to
the significance and relevance of each analysis and factor. Accordingly,
Hambrecht & Quist believes that its analyses and the summary set forth below
must be considered as a whole and that selecting portions of its analyses,
without considering all analyses, or of the summary set forth below, without
considering all factors and analyses, could create an incomplete view of the
processes underlying the analyses set forth in the Hambrecht & Quist
presentation to the Special Committee and the H&Q Opinion. In performing its
analyses, Hambrecht & Quist made numerous assumptions with respect to industry
performance, general business and economic conditions and other matters, many of
which
 
                                       15
<PAGE>   16
 
are beyond the control of the Company and Genzyme. The analyses performed by
Hambrecht & Quist (and summarized below) are not necessarily indicative of
actual values or actual future results, which may be significantly more or less
favorable than suggested by such analyses. Additionally, analyses relating to
the values of businesses do not purport to be appraisals or to reflect the
prices at which businesses actually may be sold.
 
     Analysis of Technology and Stage of Development.  Hambrecht & Quist
reviewed and analyzed, among other things, the Field in which Neozyme II is
engaged (i.e., the research, development and clinical testing of products for
the treatment of cystic fibrosis), Neozyme II's intellectual property rights
(which are limited to technology in the Field, with all technology developed by
the Company with application outside the Field being licensed back to Genzyme
exclusively on a royalty free basis) and approaches to treating CF. In
connection with its review, Hambrecht & Quist retained the outside consulting
services of an independent leading scientist in the field of CF, Dr. Rosenfeld.
The role of Dr. Rosenfeld was not to appraise or value any of the Company's
technology, but to assist Hambrecht & Quist in assessing, among other things,
the quality and progress of the Company's science and its stage of scientific
and clinical development. On the basis of its analysis, Hambrecht & Quist
observed the following: (i) the Company's most advanced approach to treating
cystic fibrosis has been gene therapy using an adenovirus vector; (ii) this
approach has encountered several significant obstacles that make the development
of a gene therapy product unlikely in the next few years (Genzyme forecasts
commercialization in 2003); (iii) while gene therapy approaches using an
adenoassociated virus or a lipid vector hold promise, these approaches are in
comparatively early stages and a pivotal trial for a particular vector is not
likely in the near future; and (iv) Genzyme's work in the areas of protein
replacement and Hypergam(TM)+CF have proved to be disappointments and
development of these products have been suspended and terminated, respectively.
 
     Comparable Company Analysis.  Hambrecht & Quist reviewed and compared
selected historical financials, operating and stock market performance data of
the Company to the corresponding data of four publicly traded biotechnology
companies with a scientific focus in the area of gene therapy (the "Gene Therapy
Companies"). The Gene Therapy Companies included in this Group were GeneMedicine
Incorporated, Somatix Therapy Corporation, Targeted Genetics Corporation and
Vical Incorporated. Hambrecht & Quist compared cash, book value, net income,
enterprise value (consisting of equity value plus debt less cash) and burn rate
(cash used in operating activities plus capital expenditures) for the latest
available 12 month period ("LTM") for each of the Gene Therapy Companies with
the Company. Hambrecht & Quist also analyzed the financial ratios of market
value to cash and market value to book value. Hambrecht & Quist calculated the
ratio of the cash position to the LTM burn rate of each of the Gene Therapy
Companies to determine the "survival index" (the number of consecutive annual
periods that such company could continue to fund cash losses at the rate
experienced in the LTM from the most recently available reported cash without
obtaining additional capital) and compared such information from such Gene
Therapy Companies with the Company. The average enterprise value of the Gene
Therapy Companies was $75.3 million ($70.3 million excluding the high and low)
compared to an enterprise value of $61.4 million for the Company based on the
Offer (assuming a value of $16.00 per Callable Warrant). Hambrecht & Quist noted
that the Gene Therapy Companies had research projects in multiple disease areas
while the Company is limited to the Field and has no rights to gene delivery or
other technology outside the Field.
 
     Hambrecht & Quist also reviewed and compared selected historical and
projected financials, operating and stock market performance data of certain
publicly traded biotechnology and pharmaceutical companies (the "Established
Companies Comparables"). This comparison provided a basis for the range of
Price-Earnings ("P/E") multiples used in further analysis, particularly the
Terminal Value (as defined below) in connection with the discounted cash flow
analyses described below. The companies included in the Established Companies
Comparables were the following: Johnson & Johnson, Merck & Co, Pfizer Inc.,
SmithKline Beecham, Glaxo-Wellcome, Chiron Corp., Amgen Inc. and Genentech Inc.
Hambrecht & Quist did not attempt to prepare any further quantitative valuation
analyses based on the Established Companies Comparables because Hambrecht &
Quist believed that any comparative multiples that might be derived based upon
earnings or other financial data of such companies would not be meaningful when
applied to the Company's operating losses.
 
                                       16
<PAGE>   17
 
     Hambrecht & Quist also reviewed and analyzed the acquisition by Chiron of
Viagene and the acquisition of Genetic Therapy by Sandoz. Hambrecht & Quist
observed that Chiron acquired Viagene in a transaction valued at $102 million,
representing a premium of 67% over the market value of Viagene stock one day
prior to the transaction's announcement and that Sandoz acquired Genetic Therapy
in a transaction valued at $295 million, representing a premium of 38% over the
market value of Genetic Therapy stock one day prior to the transaction's
announcement. Hambrecht & Quist did not attempt to prepare any further
quantitative valuation analyses based on these acquisition transactions because
Hambrecht & Quist believed that differences in the technologies of each company
and the differences in the market conditions at the time such acquisitions were
made would make such analyses meaningless.
 
     Comparable SWORD Analysis.  Hambrecht & Quist noted that the Shares had
originally been offered as part of a unit financing in which purchasers bought a
Unit consisting of (i) one Share, (ii) one Series N Warrant and (iii) one
Callable Warrant. Hambrecht & Quist reviewed and analyzed the original offering
of the Units and other comparable public offerings of special purpose funding
companies commonly referred to as Stock Warrant for Off-Balance Sheet Research
and Development Companies ("SWORDs"). Hambrecht & Quist also reviewed the stock
prices and market performances of the Units and the comparable SWORD offerings.
Where the stock of SWORD companies was repurchased by the SWORD sponsor in a
negotiated transaction and not pursuant to the original purchase option,
Hambrecht & Quist analyzed a number of factors, including the purchase price
attributable to the technology, the discount to the original purchase option
price and calculated the implied rate of return from the original offering date.
The sponsor companies of the comparable SWORD offerings included in this
analysis were ALZA Corp., Centocor, Inc. (two such offerings), Immunex
Corporation, Elan Corporation PLC (two such offerings), Genetics Institute Inc.,
Gensia, Inc., Cytogen Corp., Genzyme Corporation (including only Neozyme
Corporation and not Neozyme II Corporation), PerSeptive Biosystems Inc., and
Ligand Pharmaceuticals, Inc./Allergan, Inc. (a co-sponsored SWORD). Hambrecht &
Quist observed that the value of the average SWORD units had appreciated
(inclusive of implied appreciation where such units had been repurchased by the
sponsoring companies) approximately 71.6% (from offering date to September 19,
1996), as compared to a 63.4% increase in value of the Units. Hambrecht & Quist
also observed that, at the time of the unit offering, the average value of the
warrants at an assumed 40% volatility in the SWORD sponsoring company
represented approximately 54.6% of the aggregate SWORD unit value and that in
the case of the Company, the Genzyme warrants represented approximately 23.7% of
the value of the Unit at the time of the original offering. Accordingly,
Hambrecht & Quist observed that, of the $35.00 per Unit offering price,
approximately $8.30 per Unit was allocable to the Series N Warrants and
approximately $26.70 per Unit was allocable to the Shares and the Callable
Warrants. The Series N Warrants originally included in the Units have separated
from the Units and now trade separately under the symbol "GENZZ" (the closing
price on September 19, 1996 was $11.50 per Series N Warrant). These figures were
compared with a valuation of $29.00 per Share included in the Units and $16.00
per warrant for the Callable Warrants included in the Units. In addition,
Hambrecht & Quist observed that the discount to the original purchase option
price of SWORDs repurchased in negotiated transactions was 58.7%, compared to
61.5% for the Company pursuant to the Offer and that the rate of return in
negotiated repurchases was -9.2% for the comparable SWORD repurchases, compared
to 6.5% for the Units.
 
     Discounted Cash Flow Analysis.  Hambrecht & Quist analyzed the theoretical
valuation of the Company based on the unlevered discounted cash flow of its
projected financial performance under three scenarios: (i) the Company launches
a cystic fibrosis product in 2003 in accordance with the projections Genzyme
provided Hambrecht & Quist (the "Base Case"); (ii) the Company's anticipated
product launch is delayed until 2004 (the "Delayed Scenario"); and (iii) the
Company's anticipated product launch is accelerated by one year to 2002 (the
"Accelerated Scenario"). In all three scenarios, Hambrecht & Quist used discount
rates ranging from 25% to 40% to calculate the present value (the "Present
Value") of the Company's projected stream of after-tax cash flows through 2005.
Hambrecht & Quist then calculated a terminal value (the "Terminal Value") for
the Company which represents the hypothetical value of selling
 
                                       17
<PAGE>   18
 
the entire business at the end of 2005 and discounting the amount received from
such hypothetical sale to its net present value (using the same discount rate as
applied to the Present Value). The Terminal Value used under all scenarios was
based upon multiples of 14.0x to 24.0x projected net income for the year 2005.
The range of 14.0x to 24.0x projected net income reflects a range of P/E
multiples derived from the Established Companies Comparables. For the purposes
of this analysis, Hambrecht & Quist relied on the Genzyme's management's
estimate of projected revenues with respect to all scenarios and altered only
the year in which such revenues would be recognized, with respect to the Delayed
Scenario and the Accelerated Scenario. To estimate the total present value of
the Company's business, before giving effect to its capital structure, Hambrecht
& Quist added the Present Value to the Terminal Value.
 
     Using the Base Case, Hambrecht & Quist calculated a range of present
values, including $41.9 million at a 35% discount rate and an 18.0x exit
multiple, $72.3 million at a 30% discount rate and an 18.0x exit multiple, $50.7
million at a 35% discount rate and an 20.0x exit multiple and $84.8 million at a
30% discount rate and an 20.0x exit multiple. Using the Delayed Scenario,
Hambrecht & Quist calculated a range of present values, including $3.2 million
at a 35% discount rate and an 18.0x exit multiple, $17.0 million at a 30%
discount rate and an 18.0x exit multiple, $8.0 million at a 35% discount rate
and an 20.0x exit multiple and $23.8 million at a 30% discount rate and an 20.0x
exit multiple. Using the Accelerated Scenario, Hambrecht & Quist calculated a
range of present values, including $71.6 million at a 35% discount rate and an
18.0x exit multiple, $114.1 million at a 30% discount rate and an 18.0x exit
multiple, $82.6 million at a 35% discount rate and an 20.0x exit multiple and
$130.0 million at a 30% discount rate and an 20.0x exit multiple. Hambrecht &
Quist observed that the Offer of approximately $70.0 million (assuming a value
of $38.6 million for the Callable Warrants) for the Company fell within the
middle ranges calculated using the Base Case Scenario, above the middle ranges
calculated using the Delayed Scenario and below the middle ranges calculated
using the Accelerated Scenario.
 
     Warrant Valuation Analysis.  Hambrecht & Quist analyzed the valuation of
the Callable Warrants using the Black-Sholes option valuation formula. Such
formula suggested that the value of the warrant for two shares of General
Division Common Stock based on a range of volatility of 45% to 55% to be between
$13.03 and $16.57. Additionally, such formula suggested that the value of the
warrant for 0.135 share of Tissue Repair Common Stock based on a range of
volatility to be between $0.32 and $0.42. Hambrecht & Quist also noted that the
implied volatility based on a $16.00 warrant valuation was approximately 53.8%.
Accordingly, Hambrecht & Quist concluded that the aggregated value of the
Callable Warrants range from $32.2 million to $41.0 million, or $13.33 to $16.98
per Callable Warrant.
 
     Stock Trading History Analysis.  Hambrecht & Quist examined the trading
history of (i) the Units in terms of both price and volume from September 5,
1995 to September 4, 1996 and (ii) the Units and Genzyme common stock, compared
to the American Biotechnology Index from August 4, 1992 to September 6, 1996.
Hambrecht & Quist noted that, over the period, the Units increased in value at a
far greater rate than either Genzyme common stock or the American Biotechnology
Index, which tended to trade in parallel.
 
     No company or transaction used in the above analyses is identical to the
Company, Genzyme or the proposed transaction. Accordingly, an analysis of the
results of the foregoing is not mathematical; rather it involves complex
considerations and judgments concerning differences in financial and operating
characteristics of the companies and other factors that could affect the public
trading values of the companies or company to which they are compared. The
foregoing description of Hambrecht & Quist's opinion is qualified in its
entirety by reference to the full text of such opinion, which is attached hereto
as Annex I.
 
     Certain Relationship; Terms of Engagement.  Hambrecht & Quist, as part of
its investment banking services, is regularly engaged in the valuation of 
businesses and their securities in connection with mergers and acquisitions, 
strategic transactions, corporate restructurings, negotiated underwritings, 
secondary distributions of listed and unlisted securities, private placements 
and valuations for corporate and other purposes. The Special Committee selected 
Hambrecht & Quist to serve as its financial advisor in connection with the 
proposed transaction with Genzyme because it is an internationally recognized 
investment banking firm whose
 
                                       18
<PAGE>   19
 
professionals have substantial experience in SWORDs transactions and
transactions similar to the Offer and the Second Step Transaction. Hambrecht &
Quist has, from time to time, provided financial advisory services to Genzyme,
and has received fees for rendering these services. In July 1996, Hambrecht &
Quist acted as managing underwriter for a public offering of Genzyme Transgenics
Corporation, an affiliate of Genzyme and received as compensation fees and
commissions of approximately $312,000. In the ordinary course of business,
Hambrecht & Quist acts as a market maker and broker in the publicly traded
securities of the Company and Genzyme and receives customary compensation in
connection therewith, and also provides research coverage for Genzyme. In the
ordinary course of business, Hambrecht & Quist actively trades in the equity
securities of the Company and Genzyme for its own account and for the accounts
of its customers and, accordingly, may at any time hold a long or short position
in such securities. Hambrecht & Quist may in the future provide additional
investment banking or other financial advisory services to Genzyme.
 
     Pursuant to an engagement letter dated August 2, 1996, the Company has
agreed to pay Hambrecht & Quist a retainer in the amount of $50,000 and a fee in
connection with its services as financial advisor to the Special Committee and
the rendering of a fairness opinion. The Company has agreed to pay a fee of
$200,000 upon the delivery of the fairness opinion. The retainer and fairness
opinion fee shall be credited against any Transaction Fee (as defined below).
Upon consummation by the Company of the proposed transaction, the Company shall
pay Hambrecht & Quist a fee (the "Transaction Fee"), payable in cash on closing,
of 1.0% of the value of the consideration to be received by holders of Units
plus 3.0% of the value of the consideration to be received by holders of Units
in excess of $43.00. The Company has agreed to reimburse Hambrecht & Quist for
its reasonable out of pocket expenses, and to indemnify Hambrecht & Quist
against certain liabilities, including liabilities under the federal securities
laws or relating to or arising out of Hambrecht & Quist's engagement as
financial advisor. The amount of compensation to be paid to Hambrecht & Quist
was determined by negotiations between the Special Committee and Hambrecht &
Quist.
 
5.  REASONS FOR THE TRANSACTION; PURPOSE AND STRUCTURE OF THE TRANSACTION; PLANS
    FOR THE COMPANY AFTER THE TRANSACTION
 
     In determining to seek to acquire the Company, the Board of Directors of
Genzyme carefully considered the status of the technology and product
development of the Company, which is summarized below.
 
STATUS OF PRODUCT DEVELOPMENT
 
  Product Opportunity
 
     CF is the most common fatal genetic disease afflicting the caucasian
population. Approximately one in every 2,500 infants in the United States is
born with the disease. Although improvements have been made over the last 20
years in alleviating certain symptoms of the disease and delaying its progress,
the underlying disease remains untreated and patients have an average life
expectancy of only 29 years. There are approximately 30,000 CF patients in North
America.
 
     CF is caused by one or more mutations in the gene responsible for
determining the molecular structure of a protein called cystic fibrosis
transmembrane conductance regulator ("CFTR"). The absence of functional CFTR
protein from the membrane of airway surface cells disrupts the ion transport
mechanism of the cells and contributes to the formation of a thick, dehydrated
mucus that cannot be eliminated from the lungs in the normal fashion. Build-up
of this mucus fosters recurrent infections that cause breathing difficulties and
damage to the lungs, eventually leading to respiratory failure and death.
Elsewhere in the body, the gene defect often results in digestive, reproductive
and other problems. Such other problems are unlikely to be alleviated in the
event CF-induced airway and lung damage is effectively treated.
 
     Neozyme II's work relating to the treatment of CF initially concentrated on
two promising therapies to correct the basic defect in CF airway cells: gene
therapy to augment the mutant genes with genes that would enable the patient's
cells to produce normal CFTR protein, and protein replacement therapy to augment
the missing or defective CFTR protein with properly functioning CFTR protein.
For technical and competitive reasons, the gene therapy approach has been
emphasized during the last two years, and currently the protein replacement
program is largely inactive. Neozyme II also funded NABI's efforts to develop
passive

immunization antibody products primarily for the prevention and treatment of
bacterial infections common in CF patients. See "HyperGAM(TM)+CF" below.
 
  Progress to Date
 
     The gene responsible for the defective protein present in CF patients was
identified by scientists at the University of Michigan and the Hospital for Sick
Children in Toronto and their findings were published in 1989. Since that time,
and on behalf of Neozyme II since March 1992, Genzyme scientists have
intensively studied the gene and the protein and have made significant technical
progress that should facilitate the development of effective therapies for the
treatment of CF patients. These results have been published in leading
scientific journals, and Genzyme has filed United States and foreign patent
applications covering certain aspects of this work.
 
     GENE THERAPY.  Gene therapy is a promising new technique being developed as
a treatment for several genetic diseases including CF. To date, over 139
protocols for preliminary clinical studies of gene therapy for a variety of
diseases have been approved by the National Institutes of Health.
 
     Because of the innovative nature of gene therapy and public policy issues
surrounding the insertion of new genetic information into cells, the Company
expects that early clinical evaluation will continue to entail especially
careful testing in a limited number of patients. On behalf of Neozyme II,
Genzyme is currently conducting preliminary clinical testing of Neozyme II's
gene therapy products. The timing and results of these initial studies will
determine whether and when pivotal trials to determine safety and effectiveness
will be undertaken. These pivotal trials may involve large groups of patients
for lengthy periods of time in order to address the uncertainties surrounding
insertion of new genetic information into humans and to show clinical
effectiveness in the treatment of a progressive disease. All of Genzyme's
efforts related to gene therapies for CF are funded by Neozyme II.
 
     On behalf of Neozyme II, Genzyme scientists have demonstrated that the
defective ion transport mechanism present in airway cells taken from CF patients
can be corrected in vitro by the insertion of normal CFTR genes into the cells.
However, the techniques for inserting genetic material into cells outside the
body are not expected to be useful in gene therapy for CF because there is no
practical way to remove and re-implant cells from the airways of CF patients.
For this reason, Neozyme II's proposed gene therapy Product will likely need to
be administered directly to the airways of the lung. Neozyme II believes that
its gene therapy Product would need to be readministered periodically as the
transferred gene ceases to function or is lost and as the treated cells
naturally die and are replaced.
 
     Vectors are presently regarded as critical components of gene therapeutics
which facilitate targeting and delivery of genetic material to the appropriate
cells and affect the efficiency and duration of gene expression. On behalf of
Neozyme II, Genzyme is developing both viral and non-viral vectors for
delivering the gene encoding CFTR to the surface cells lining the airways.
Animal studies aimed at demonstrating the potential safety and effectiveness of
a variety of vectors have been initiated and several have been successfully
completed and reported in scientific journals.
 
     Viral Vectors.  On behalf of Neozyme II, Genzyme and collaborators at the
University of Iowa, in 1993, conducted a small study in CF patients using an
adenovirus-gene product administered to nasal epithelium. Results collected from
the study showed that it is possible to correct the biochemical defect in CF
cells in nasal epithelium in vivo. The study results, published in October 1993,
were the first published report of a successful gene transfer in CF patients and
the first successful application of an adenovirus vector in gene therapy.
However, in a 1995 publication reporting the results of a similar study,
researchers from the University of North Carolina questioned the efficacy of
gene transfer using adenovirus.
 
     In December 1993, a Genzyme collaborator received Recombinant DNA Advisory
Committee ("RAC") approval for a study involving repeat administration of
Genzyme's second generation adenovirus vector to the nasal epithelium and sinus
passages of CF patients. The nasal part of this study was initiated during the
first quarter of 1994 and was completed in the second quarter of 1995.
Aggregated data from this study showed limited evidence of gene expression at
the intermediate doses but not at the highest dose. The
 
                                       20
<PAGE>   21
 
virus appeared safe, but a complex immune response to the adenovirus was
measured in almost all patients. This and other data obtained in animals and
submitted for publication in 1995 suggest that immune response may limit the
efficacy of repeat dose therapy with adenovirus. The sinus study was not
conducted due to the lack of interpretable baseline data in the CF sinus.
 
     During the fourth quarter of 1994, Genzyme received RAC approval and
submitted a protocol to the United States Food and Drug Administration (the
"FDA") for a two part safety study involving administration of its second
generation adenovirus vector to the lungs of up to 40 CF patients via
bronchoscope and aerosol. Bronchoscopic administration commenced in the first
quarter of 1995, and aerosol administration commenced in September 1995.
Additionally, in September 1995, Genzyme switched to the use of a third-
generation adenovirus vector with an improved safety profile as part of this
same study. The study is currently ongoing.
 
     In parallel with these clinical studies, Genzyme, on behalf of Neozyme II,
is conducting extensive research into proving the safety and efficacy of
adenovirus. Particular emphasis is being placed on immunology, since it now
appears that new vectors or methods need to be developed so as to reduce the
patient's immune response and to increase the efficacy of adenovirus vectors.
Such improvements may be necessary in order for adenovirus vectors to be
clinically useful in chronic therapy.
 
     Non-Viral Vectors.  In addition to pursuing adenovirus and other viral
vectors, Neozyme II is developing lipid-DNA complexes as vectors for gene
therapy. Neozyme II believes that lipid-based vectors may offer advantages due
to their reduced immunogenicity and ease of manufacture relative to viral
vectors. Genzyme has synthesized, evaluated and filed patent applications on
numerous new lipids. Several of these have shown significantly greater activity
in vivo than commercially available lipids. To augment its internal efforts,
Genzyme has entered into arrangements with third parties to gain access to
non-viral gene delivery technologies. To date, the most significant such
arrangement is an October 1993 exclusive research agreement with Vical, Inc. to
evaluate Vical's cytofectins as non-viral gene delivery vectors for treating CF.
The plasmid expression system containing the DNA also affects expression
efficiency, and Genzyme has designed various new plasmid constructs to enhance
expression. Although substantial progress has been made in both lipid and
plasmid constructs, currently the optimal formulation of the best lipid-DNA
complex is still less efficient than adenovirus as measured in single dose in
vivo experiments.
 
     In December 1993, a Genzyme collaborator received RAC approval for a CF
nasal protocol utilizing a lipid-DNA complex containing DMRIE, one of Vical's
proprietary cytofectins. This study commenced in September 1995 and is currently
ongoing. In December 1994, Genzyme also initiated a collaboration with a British
academic group for purposes of further studying Neozyme II's proprietary
lipid-DNA complexes.
 
     In December 1995, Genzyme submitted an IND to the FDA for a nasal study
using a proprietary lipid-DNA complex developed by Genzyme. The study was
initiated in January 1996 by Genzyme and its collaborators at the University of
Iowa and completed in the second quarter of 1996. The study entailed the
administration of the lipid- DNA complex to one nostril of nine CF patients and
administration of the DNA plasmid alone to the patients' other nostril as a
control. Although the results showed that the lipid-DNA compound was well
tolerated, they did not demonstrate the lipid-DNA compound to be superior to the
plasmid DNA in improving ion exchange across the cell membrane. A follow-on
study to gather additional information is planned for later this year.
 
     Also in the second quarter of 1996, Genzyme completed a safety study in
which the lipid alone was delivered in aerosol form to the lungs of 15 non-CF
volunteers. The study showed that aerosolized delivery of the lipid to the lung
was well tolerated. Based on these results, a pilot study involving aerosol
administration of a lipid-DNA complex to the lungs of CF patients was planned to
start later this year in the United Kingdom ("UK"). The commencement of this
trial was placed on hold by the UK Medicines Control Agency ("MCA"), pending
resolution of certain safety issues raised by the MCA. Genzyme has responded to
these issues and submitted a revised protocol for the trial. There can be no
assurance that the MCA will accept the revised protocol or require additional
data that would further delay the trial. In the event that the revised protocol
is not accepted, Genzyme plans to revise the IND currently on file with the FDA
for the lipid-DNA complex to include an aerosol protocol.
 
                                       21

     Protein Replacement Therapy.  CFTR is a membrane protein, a class of
molecules which historically has been difficult to produce in conventional cell
culture in active form and large quantities. Genzyme, however, has been able to
develop recombinant cell lines that can synthesize the protein and has published
data on the feasibility at laboratory scale of producing and purifying
functional CFTR protein from mammalian and insect cells. In collaboration with
researchers at Tufts University and Genzyme Transgenics Corporation, transgenic
expression techniques were used successfully to breed mice and rabbits that
secrete human CFTR protein in their milk. Based on these results, Genzyme
engaged Genzyme Transgenics Corporation to develop transgenic goats that express
CFTR in their milk. Although one transgenic goat has been born, it did not
synthesize measurable CFTR in its milk and no further work is currently
underway.
 
     As a membrane protein, CFTR must be delivered into the cell membrane to be
effective. On behalf of Neozyme II, Genzyme has investigated various methods to
deliver the CFTR protein across the planar bilayer of epithelial cells. In 1995,
Genzyme reported in several publications the technical feasibility of delivering
small but detectable amounts of functional CFTR to epithelial cells in vitro
using virosomes. However, the effect detected was transient.
 
     As a theoretical matter, gene therapy is significantly more efficient than
protein replacement because each DNA particle delivered will produce multiple
copies of protein; whereas, in protein replacement, each delivered unit results
in delivery of only one protein molecule. Both protein replacement and gene
therapy have significant technical challenges related to delivery, but since
gene therapy is more efficient once delivered, Genzyme has chosen to concentrate
its efforts in this area. Although still a potentially viable approach,
currently the protein replacement program is largely inactive.
 
     HyperGAM(TM)+CF.  In August 1993, Genzyme entered into an alliance with
NABI to develop a polyclonal antibody product called HyperGAM(TM)+CF for use in
passive immunization of CF patients infected with Pseudomonas bacteria, which
are a major medical problem associated with CF and a frequent cause of
hospitalization. Neozyme II believed that HyperGAM(TM)+CF could be complementary
to the Company's gene therapy or protein replacement products by preventing or
treating Pseudomonas infections in conjunction with correcting the basic defect
in airway cells. In exchange for funding Genzyme's share of NABI's development
costs, Neozyme II received the exclusive right to market HyperGAM(TM)+CF
worldwide and share in the profits with NABI.
 
     A Phase I clinical trial involving single dose administration of
HyperGAM(TM)+CF was completed in 1994 and showed that HyperGAM(TM)+CF appeared
to be safe and supported a monthly dosing regimen. A multi-center, dose ranging
Phase II clinical trial to assess safety and efficacy of the product in chronic
administration commenced in the first quarter of 1995. In June 1996, Neozyme II
and NABI announced the halt of the Phase II clinical trial for HyperGAM(TM)+CF
because an interim analysis of the trial data showed no evidence of a reduction
in the number of acute pulmonary exacerbations in trial participants. No major
issues with the safety of the product were identified. On June 21, 1996, after
review of the interim analysis data, the Board of Directors of Neozyme II voted
unanimously to terminate the license and development agreement with NABI. Under
the terms of the agreement with NABI, Neozyme II is required to reimburse NABI
for certain costs incurred in connection with the wind down of the
HyperGAM(TM)+CF program up to a maximum of $900,000.
 
REASONS FOR THE TRANSACTION
 
     Genzyme believes that a gene-based therapy for CF represents the most
promising approach for addressing this important unmet medical need. Despite
significant development progress under the CF Program, however, the key
milestone of demonstrating clinical efficacy of a gene therapy approach has not
been and, Genzyme believes, will not be demonstrated until well after the
expiration of the Purchase Option on December 31, 1996, if at all. Accordingly,
Genzyme believes the value of Neozyme II is significantly below the current
Purchase Option Exercise Price and, absent unforeseen progress in the CF
Program, Genzyme does not intend to exercise the Purchase Option.
 
     Notwithstanding the present intention not to exercise the Purchase Option,
the Genzyme Board of Directors has determined that the acquisition of Neozyme II
at this time on and subject to the terms of the Purchase Agreement is in the
best interests of Genzyme and its stockholders for the following reasons:
 
                                       22
<PAGE>   23
 
     Acceptable Valuation and Timing; Avoid Dilution.  Genzyme believes that the
Offer allows Genzyme to acquire Neozyme II at a price that appropriately
reflects the value of Neozyme II at its current stage of development and within
the time frame contemplated at the inception of Neozyme II. In addition, if the
Offer is consummated, the number of outstanding warrants to acquire Genzyme
stock will be significantly reduced, thereby reducing potential future dilution
of Genzyme stock.
 
     Continuity of Program Development.  Genzyme desires to maintain its
commitment to the CF community to continue the research, development and
clinical evaluation of the two gene therapy approaches currently being evaluated
in the CF Program in an effort to reach the key milestone of demonstrating
clinical efficacy as soon as possible. Genzyme expects, however, that advancing
the CF Program through demonstration of clinical efficacy will require
significant additional investment materially in excess of the remaining
resources available from Neozyme II, which resources will be substantially
depleted by the end of 1996. In the event that the Offer is rejected, Neozyme II
will be required to seek alternative sources of capital to continue funding the
CF Program, such as raising additional capital, an acquisition by a third party
or some form of collaboration with a third party. Genzyme believes that any such
alternative would involve significant time, expense and uncertainty and, more
important, could result in the interruption of the research, development and
clinical evaluation efforts being conducted under the CF Program. Any such
interruption could have a material adverse effect on the time required to
demonstrate clinical efficacy. Acquiring Neozyme II at this time, therefore,
allows Genzyme to maintain its commitment to the CF community, while preserving
the continuity of its CF development efforts.
 
     Preservation of Competitive Advantage.  While the CF Program has
experienced setbacks relating to the failure of HyperGAM(TM)+CF and the largely
inactive status of the protein replacement program due to the significant
technical challenges related to this approach, Genzyme believes that, with both
viral and non-viral vector systems in clinical evaluation for CF, the CF Program
is the most comprehensive program among those competitors active in the CF
field. Substantially all of the value created by the CF Program derives,
however, from the intellectual property developed under the CF Program. In the
event that Neozyme II is required to seek alternative sources of capital to
continue funding the CF Program, Genzyme believes that Neozyme II would be
required to disclose such intellectual property to interested third parties,
including existing or potential competitors, in connection with seeking such
funding and that such disclosure notwithstanding the existence of non-disclosure
agreements, could jeopardize the competitive position and diminish the value of
the CF Program and related gene delivery technology developed by Genzyme.
Genzyme believes that the acquisition of Neozyme II by Genzyme at this time
would avoid the risks of such disclosure and, accordingly, would allow Genzyme
to preserve the competitive advantage of the CF Program.
 
     Investor Relations.  If the Offer is not successful and Neozyme II seeks
alternative sources of funding, absent unforeseen progress in the CF Program,
Genzyme may determine not to make any acquisition proposal upon expiration of
the Purchase Option or, if Genzyme determines to make a subsequent proposal, it
is likely that such proposal would be at a price below $45 per Unit. As also
noted above, Genzyme expects that substantial commitments in time and capital
will be required to advance the CF Program through a demonstration of clinical
efficacy. In view of these commitments, the value realizable by the existing
investors in Neozyme II could fall well below the $45 per Unit now being offered
by Genzyme. Accordingly, Genzyme believes that effecting the Offer at this time
at a premium to the market price of the Units at the time that an agreement in
principal was reached will allow investors to realize a fair price for their
investment, while avoiding the risk of any such future decline in the value of
Neozyme II.
 
     Potential Gene Therapy Collaborations.  Genzyme views the CF market and the
gene therapy approach as an attractive opportunity that fits well with Genzyme's
corporate objectives of developing novel therapeutics to address significant
unmet medical needs. In particular, Genzyme has developed significant expertise
outside of the CF field and the acquisition of rights to gene therapy-based
programs within the CF field provides Genzyme with the ability to accelerate its
overall gene therapy development by continuing work on the most advanced
programs, thereby making Genzyme a more attractive partner.
 
     In reaching its determination that the acquisition of Neozyme II at this
time on and subject to the terms of the Offer and the Second Step Transaction is
fair to and in the best interests of Genzyme and its
 
                                       23
<PAGE>   24
 
stockholders, the Genzyme Board of Directors evaluated the factors considered by
it in light of the directors' knowledge of the business and operations of
Genzyme and Neozyme II and their respective business judgments. In addition, the
Genzyme Board considered the presentation made to it on September 17, 1996 by
Robertson, Stephens & Company (the "Robertson, Stephens & Company Presentation")
and the written opinion, dated September 20, 1996, of Robertson, Stephens &
Company (the "Robertson Stephens Opinion") (a copy of which is attached hereto
as Annex II) that, based upon and subject to the factors and assumptions set
forth in such opinion, the Offer Price was fair to Genzyme from a financial
point of view. The Genzyme Board of Directors did not find it practicable to and
did not quantify or assign relative weight to the specific factors considered by
it in reaching its determination. A detailed description of the Robertson,
Stephens & Company Presentation and the Robertson, Stephens & Company Opinion
are set forth below.
 
OPINION OF FINANCIAL ADVISOR TO GENZYME
 
     Robertson, Stephens & Company is acting as Genzyme's exclusive financial
advisor and as Dealer Manager in connection with the Offer. Robertson, Stephens
& Company was engaged on the basis of its experience as a financial advisor in
connection with mergers and acquisitions as well as on its industry knowledge
and familiarity with the Company.
 
     At a special meeting of the Genzyme Board held on September 17, 1996,
Robertson, Stephens & Company made the Robertson, Stephens & Company
Presentation and, on September 20, 1996, Robertson, Stephens & Company delivered
the Robertson, Stephens & Company Opinion to the Genzyme Board. No limitations
were imposed by the Genzyme Board upon Robertson, Stephens & Company with
respect to investigations made or procedures followed by Robertson, Stephens &
Company in rendering the Robertson, Stephens & Company Opinion. Robertson,
Stephens & Company was not requested to opine as to the fairness of the Offer
Price to the Company or to the Holders or the fairness of the consideration to
be paid by Genzyme pursuant to the Second Step Transaction.
 
     The full text of the Robertson, Stephens & Company Opinion, which sets
forth the assumptions made, matters considered and limitations on the review
undertaken by Robertson, Stephens & Company, is attached as Annex II to this
Offer to Purchase and is incorporated herein by reference. The Robertson,
Stephens & Company Opinion has been provided to the Genzyme Board for its
information. It is directed only to the fairness from a financial point of view
to Genzyme of the Offer Price and does not constitute a recommendation to any
Holder as to whether such Holder should tender any or all of its Units pursuant
to the Offer. The summary of the Robertson, Stephens & Company Opinion set forth
in this Offer to Purchase is qualified in its entirety by reference to the full
text of the opinion set forth in Annex II and incorporated herein by reference.
 
     The summary set forth below does not purport to be a complete description
of the analyses underlying the Robertson, Stephens & Company Opinion or the
Robertson, Stephens & Company Presentation. The preparation of a fairness
opinion is a complex analytic process involving various determinations as to the
most appropriate and relevant methods of financial analysis and the application
of those methods to the particular circumstances and, therefore, such an opinion
is not readily susceptible to partial analysis or summary description. In
arriving at its opinion, Robertson, Stephens & Company did not attribute any
particular weight to any analysis or factor considered by it, but rather made
qualitative judgments as to the significance and relevance of each analysis and
factor. Accordingly, Robertson, Stephens & Company believes that its analyses
must be considered as a whole and that selecting portions of its analyses,
without considering all analyses, would create an incomplete view of the process
underlying its opinion.
 
     For purposes of the Robertson, Stephens & Company Opinion, Robertson,
Stephens & Company, among other things: (i) reviewed financial information
regarding the Company furnished to Robertson, Stephens & Company by the Company,
including certain financial forecasts prepared by the management of the Company;
(ii) reviewed publicly available information regarding the Company; (iii) held
discussions with the management of the Company concerning the business, past and
current business operations, financial condition and future prospects of the
Company; (iv) reviewed a draft dated September 20, 1996 of the Purchase
Agreement; (v) reviewed the stock price and trading history of the Company; (vi)
reviewed the valuations of publicly traded companies that Robertson, Stephens &
Company deemed comparable to the
 
                                       24
<PAGE>   25
 
Company; (vii) compared the financial terms of the Offer with other transactions
which Robertson, Stephens & Company deemed relevant; (viii) prepared a
discounted cash flow analysis of the Company; (ix) analyzed the value of the
Callable Warrants; and (x) made such other studies and inquiries, and reviewed
such other data, as Robertson, Stephens & Company deemed relevant.
 
     In arriving at its opinion, Robertson, Stephens & Company did not
independently verify any of the foregoing information and relied on all such
information being complete and accurate in all material respects. Furthermore,
Robertson, Stephens & Company did not make any independent appraisal of the
properties or assets and liabilities of the Company, nor was Robertson, Stephens
& Company furnished with any such evaluations or appraisals. With respect to the
financial forecasts (and the assumptions and bases therefor) of the Company
provided to Robertson, Stephens & Company by the management of the Company,
Robertson, Stephens & Company assumed that such forecasts had been reasonably
prepared in good faith on the basis of reasonable assumptions and reflected the
best available estimates and judgments of the management of the Company as to
the likely future financial performance of the Company. In that regard,
Robertson, Stephens & Company relied on the assumptions of the management of the
Company with respect to the effect on such forecasts of the potential outcome of
the Company's pending patent applications. The Robertson, Stephens & Company
Opinion was necessarily based upon market, economic, and other conditions that
existed and could be evaluated as of the date of the Robertson, Stephens &
Company Opinion and on information available to Robertson, Stephens & Company as
of such date.
 
     The following is a summary of the analyses performed by Robertson, Stephens
& Company in connection with the preparation of the Robertson, Stephens &
Company Presentation and the Robertson, Stephens & Company Opinion. A copy of
the Robertson, Stephens & Company Presentation will be made available for
inspection and copying at the principal executive offices of Genzyme during
regular business hours by any interested Holder, or his representative who has
been so designated in writing.
 
  STOCK PRICE AND TRADING HISTORY
 
     Robertson, Stephens & Company reviewed the trading activity of the Units
and the Series N Warrants, including the daily closing price and daily volume of
each of the Units and the Series N Warrants, for the period from January 3, 1995
to September 13, 1996 and identified certain events that had a significant
effect on the prices of the Units and the Series N Warrants.
 
  VALUATION ANALYSIS
 
     Introduction.  In valuing the Units, Robertson, Stephens & Company
performed a comparable company analysis, a comparable transaction analysis, a
discounted cash flow analysis and a warrant valuation analysis, each of which is
described in detail below. The comparable company analysis, comparable
transaction analysis for acquisitions of non-SWORDS (as defined below) and
discounted cash flow analysis were used to determine ranges for the Technology
Value (as defined below) of the Company. The comparable transaction analysis for
acquisitions of SWORDS was used to calculate the premiums paid by acquiring
companies in comparable acquisitions in order to determine the Equity Value (as
defined below) of the Company. For the warrant valuation analysis, Robertson,
Stephens & Company used the Black-Scholes formula to determine an implied value
per Callable Warrant. By adding to the Technology Value the implied aggregate
value of the Callable Warrants, based on an implied value, solely for purposes
of this analysis, per Callable Warrant of $15.12, Robertson, Stephens & Company
determined the equity value of the Company (the "Equity Value"), which
represents the aggregate market capitalization of the Units.
 
     Comparable Company Analysis.  Robertson, Stephens & Company performed an
analysis of companies engaged in research and development activities in the area
of gene therapy and which are considered by Robertson, Stephens & Company to be
reasonably comparable to the Company. The Tier 1 companies identified by
Robertson, Stephens & Company comprise Somatix Therapy Corporation and Vical
Incorporated (the "Tier 1 Companies"), and the Tier 2a companies identified by
Robertson, Stephens & Company comprise Avigen, Inc., Cell Genesys, Inc.,
GeneMedicine, Inc. and Targeted Genetics Corporation (the "Tier 2a Companies").
Robertson, Stephens & Company identified as the Tier 2b companies Immusol, Inc.,
 
                                       25
<PAGE>   26
 
Introgen Therapeutics, Inc. and Transkaryotic Therapies, Inc. (the "Tier 2b
Companies"), each of which had recently filed a registration statement with
respect to an initial public offering. Robertson, Stephens & Company noted that
the Tier 1 Companies generally trade at significantly higher market
capitalizations than the Tier 2a Companies because they have one or more of the
following characteristics: (i) more enabling technologies, (ii) more substantial
corporate endorsements, (iii) broader patent estates, (iv) later stages of
clinical development and (v) more significant disease market opportunities.
 
     Robertson, Stephens & Company then determined a Technology Value range. For
purposes of this methodology, Robertson, Stephens & Company defined Technology
Value as the market capitalization less cash and cash equivalents for each of
the comparable companies. For the Tier 1 Companies and the Tier 2a Companies,
market capitalization was based on market data as of September 13, 1996. For the
Tier 2b Companies, market capitalization was based on the mid-point of the
proposed initial public offering price disclosed in each such company's
registration statement and the expected number of fully diluted shares
outstanding immediately after such offering.
 
     Based on this analysis, Robertson, Stephens & Company determined a range of
Technology Value of (i) between $104.7 million and $169.3 million for the Tier 1
Companies, (ii) between $28.4 million and $57.5 million for the Tier 2a
Companies and (iii) between $115.4 and $168.5 million for the Tier 2b Companies.
By including the implied value of the Callable Warrants, Robertson, Stephens &
Company calculated a range of Equity Value of (i) between $141.2 million and
$205.8 million, or $58.46 and $85.23 per Unit, based on the Tier 1 Companies,
(ii) between $64.9 million and $94.0 million, or $26.89 and $38.91 per Unit,
based on the Tier 2a Companies and (iii) between $151.9 million and $205.0
million, or $62.90 and $84.90 per Unit, based on the Tier 2b Companies.
 
     Robertson, Stephens & Company also reviewed the trading performance of the
Units over the period from January 3, 1995 to September 13, 1996 and compared
such performance with that of indices representing the average trading prices
for each of the Tier 1 Companies and the Tier 2a Companies. Such review
indicated that, over such period, the trading price of the Units, the Tier 1
Companies and the Tier 2a Companies increased by 55.5%, 82.7% and 0.4%,
respectively.
 
     No company utilized in the comparable company analysis was identical to the
Company. In particular, Robertson, Stephens & Company noted that the Company's
assets are limited to determining the application of potential gene therapy
products in the treatment of CF only. Certain of the comparable companies have
broader gene therapy technology programs, with potential applications to CF and
the treatment of other diseases. Accordingly, an analysis of the results of such
a comparison is not purely mathematical as several factors that are not relevant
to the Company could affect the public trading value of the comparable companies
to which the Company is being compared.
 
     Comparable Transaction Analysis: Acquisitions of SWORDS
Companies.  Robertson, Stephens & Company analyzed publicly available
information for 11 Stock/Warrant for Off balance sheet Research and Development
Subsidiary ("SWORDS") acquisitions within the biopharmaceutical industry (the
"SWORDS Acquisitions") considered by Robertson, Stephens & Company to be
reasonably comparable to the Company. The SWORDS Acquisitions analyzed were: (i)
PerSeptive Biosystems, Inc.'s acquisition of PerSeptive Technologies II
Corporation, (ii) Elan Corporation, plc's acquisition of Advanced Therapeutic
Systems Limited, (iii) Cytogen Corporation's acquisition of CytoRad Corporation,
(iv) Centocor, Inc.'s acquisition of Tocor II, Inc., (v) Gensia Pharmaceuticals
Inc.'s acquisition of Aramed, Inc., (vi) Genetics Institute, Inc.'s acquisition
of SciGenics Incorporated, (vii) Genzyme Corporation's acquisition of Neozyme I
Corporation, (viii) Elan Corporation, plc's acquisition of Drug Research Corp.,
(ix) Immunex Corporation's acquisition of Receptech Corp., (x) Centocor, Inc.'s
acquisition of Tocor, Inc. and (xi) Alza NV's acquisition of Bio-Electro
Systems, Inc. In five of the SWORDS Acquisitions, the acquiring sponsor company
exercised its contractual option to acquire the SWORDS company. The other six
SWORDS Acquisitions were negotiated transactions at prices below the option
exercise price.
 
     For each of the SWORDS Acquisitions, Robertson, Stephens & Company
determined (i) the annual compounded return, (ii) the premium paid to the SWORDS
unit price, or to the aggregate price of the SWORDS common stock and the
detachable warrants to acquire the common stock of the sponsor company
 
                                       26
<PAGE>   27
 
("Sponsor Warrants") for those SWORDS whose Sponsor Warrants had detached from
the SWORDS units and were trading separately (the "Combined Premium"), 28 days
prior to the date of announcement of the SWORDS Acquisition and (iii) the
premium paid to the SWORDS unit price, or to the SWORDS common stock price for
those SWORDS whose Sponsor Warrants had detached from the SWORDS units and were
trading separately (the "Ex-Sponsor Warrant Premium"), 28 days prior to the date
of announcement of the SWORDS Acquisition. Robertson, Stephens & Company
determined that (i) the annual compounded return for the SWORDS Acquisitions
ranged from -28.5% to 42.9%, (ii) the Combined Premium ranged from -3.6% to
135.6% and (iii) the Ex-Sponsor Warrant Premium ranged from 1.5% to 143.8%.
Excluding the SWORDS Acquisitions effected upon the exercise of the sponsor
company's contractual purchase option, such ranges were -28.5% to 26.4%, -3.6%
to 135.6% and 2.8% to 143.8%, respectively.
 
     Robertson, Stephens & Company calculated a range for the Equity Value by
(i) applying the annual compounded return to the Unit Offering price of $35.00
per Unit and (ii) applying the Ex-Sponsor Warrant Premium to the market price of
the Units as of September 5, 1996. In each such case, Robertson, Stephens &
Company excluded from its analysis the SWORDS Acquisitions effected upon the
exercise of a contractual purchase option. Based on this analysis, Robertson,
Stephens & Company calculated ranges of Equity Value of (i) between -$7.2
million and $209.4 million, or -$2.97 and $86.71 per Unit, applying the annual
compounded return, and (ii) between $110.1 million and $261.2 million, or $45.60
and $108.16 per Unit, applying the Ex-Sponsor Warrant Premium.
 
     No company utilized in the comparable SWORDS Acquisitions analysis was
identical to the Company, and no transaction utilized in the comparable SWORDS
Acquisitions analysis was identical to the Offer and Second Step Transaction.
Accordingly, an analysis of the results of such a comparison is not purely
mathematical but instead involves complex considerations and judgments
concerning differences in historical and projected financial and operating
characteristics of the comparable companies and other factors that could affect
the acquisition value of such companies and the Company.
 
     Comparable Transaction Analysis: Acquisitions of Non-SWORDS Early-Stage
Biotechnology Companies.  Robertson, Stephens & Company analyzed publicly
available information for seven acquisitions of non-SWORDS, early-stage
biotechnology companies (the "Non-SWORDS Acquisitions") considered by Robertson,
Stephens & Company to be reasonably comparable to the Company (each, an
"Acquired Company"). The Non-SWORDS Acquisitions analyzed were: (i) Targeted
Genetics Corporation's acquisition of RGene Therapeutics, Inc., (ii)
Schering-Plough Corporation's acquisition of Canji, Inc., (iii) Rhone-Poulenc
Rorer Inc.'s acquisition of Applied Immune Sciences, Inc., (iv) Sandoz AG's
acquisition of Genetic Therapy, Inc., (v) Cytogen Corporation's acquisition of
Cellcor, Inc., (vi) Chiron Corporation's acquisition of Viagene, Inc. and (vii)
Ligand Pharmaceuticals Incorporated's acquisition of Glycomed Incorporated.
 
     For the Non-SWORDS Acquisitions, Robertson, Stephens & Company calculated
the price paid by the acquiring company as a multiple of (i) the total research
and development expenses accrued for the Acquired Company since its inception
including, where applicable, in-process research and development (the "R&D
Multiple") and (ii) the Technology Value of the Acquired Company (the
"Technology Value Multiple"). For purposes of this methodology, Robertson,
Stephens & Company defined Technology Value as the equity market capitalization
of the Acquired Company one month prior to the announcement date of the
acquisition plus total debt less current cash. In addition, Robertson, Stephens
& Company calculated the premium paid for the Acquired Company to the price per
share of the Common Stock of the Acquired Company (a) one day prior to the
announcement date of the acquisition (the "One Day Premium") and (b) one month
prior to the announcement date of the acquisition (the "One Month Premium").
Robertson, Stephens & Company excluded from its acquisition premium analysis two
of the Acquired Companies that were not publicly traded as of the date of the
acquisition. Robertson, Stephens & Company determined that (i) the R&D Multiple
ranged from 0.7x to 7.4x, (ii) the Technology Value Multiple ranged from 1.5x to
3.1x, (iii) the One Day Premium ranged from 33.0% to 149.4% and (iv) the One
Month Premium ranged from 35.3% to 95.3%.
 
     Robertson, Stephens & Company calculated a range for the Equity Value by
applying (i) the R&D Multiple to total research and development expenses for the
CFTR gene therapy program (but not for the HyperGAM(TM)+CF and CFTR protein
replacement therapy programs) since the inception of the Company of
 
                                       27
<PAGE>   28
 
$36.6 million, (ii) the Technology Value Multiple to an estimated Technology
Value (which, solely for purposes of this analysis, Robertson, Stephens &
Company deemed to be $71.0 million, calculated as the market value of the
Company as of September 13, 1996 less the implied aggregate value of the
Callable Warrants), (iii) the One Day Premium to an acquisition price of $29.25
per share of the Callable Common Stock and (iv) the One Month Premium to an
acquisition price of $29.25 per share of the Callable Common Stock. Based on
this analysis, Robertson, Stephens & Company calculated a range of Equity Value
of (a) between $61.2 million and $306.6 million, or $25.36 and $126.94 per Unit,
applying the R&D Multiple, (b) between $140.5 million and $256.1 million, or
$58.18 and $106.06 per Unit, applying the Technology Value Multiple, (c) between
$130.5 million and $212.7 million, or $54.03 and $88.06 per Unit, applying the
One Day Premium, and (d) between $132.1 million and $174.5 million, or $54.70
and $72.27 per Unit, applying the One Month Premium.
 
     No company utilized in the comparable Non-SWORDS Acquisitions transaction
analysis was identical to the Company, and no transaction utilized in the
comparable Non-SWORDS Acquisitions analysis was identical to the Offer and the
Second Step Transaction. Accordingly, an analysis of the results of such a
comparison is not purely mathematical but instead involves complex
considerations and judgments concerning differences in historical and projected
financial and operating characteristics of the comparable companies and other
factors that could affect the acquisition value of such companies and the
Company.
 
     Discounted Cash Flow Analysis.  Robertson, Stephens & Company performed a
discounted cash flow analysis of the projected cash flows of the Company for the
years 1997 through 2006 to 2008, based upon projections provided to Robertson,
Stephens & Company by the management of the Company. In conducting its
discounted cash flow analysis, Robertson, Stephens & Company utilized
projections representing three cases, each developed by the management of the
Company. These cases consisted of a base case (the "Base Case") and two adjusted
cases (the "Upside Case" and the "Downside Case"). In developing the three
cases, the management of the Company made certain assumptions regarding (i)
patient growth, (ii) market penetration, (iii) non-U.S. revenues and (iv)
royalty income. None of the cases assigned any value to discontinued or
suspended research operations, including the HyperGAM(TM)+CF and CFTR protein
replacement therapy programs.
 
     For each of the three cases, Robertson, Stephens & Company calculated a
range for the Technology Value. For purposes of this analysis, Robertson,
Stephens & Company utilized discount rates ranging from 30.0% to 35.0% and
terminal value multiples of earnings before interest and taxes ("EBIT") ranging
from 8.0x to 10.0x.
 
     Based on this analysis, Robertson, Stephens & Company calculated a range of
Technology Value of (i) between $20.9 million and $85.0 million, or $8.64 and
$35.19 per share of the Callable Common Stock, based on the Base Case, (ii)
between $49.9 million and $153.8 million, or $20.68 and $63.69 per share of the
Callable Common Stock, based on the Upside Case, and (iii) between $4.0 million
and $61.4 million, or $1.65 and $25.41 per share of the Callable Common Stock,
based on the Downside Case. By including the implied value of $15.12 per
Callable Warrant, Robertson, Stephens & Company calculated a range of Equity
Value of (i) between $57.4 million and $121.5 million, or $23.78 and $50.32 per
Unit, based on the Base Case, (ii) between $86.4 million and $190.3 million, or
$35.79 and $78.81 per Unit, based on the Upside Case, and (iii) between $40.5
million and $97.9 million, or $16.78 and $40.55 per Unit, based on the Downside
Case. Robertson, Stephens & Company noted that a discounted cash flow analysis
is a less reliable indicator of value for an early-stage biopharmaceutical
company such as the Company due to, among other things, the uncertainties in
developing a therapeutic product that satisfies both regulatory and market
requirements.
 
     Valuation of Callable Warrants.  Robertson, Stephens & Company also
performed a valuation of the maximum theoretical price per Callable Warrant by
using the Black-Scholes formula for valuing warrants of publicly traded
companies. The Black-Scholes formula incorporates the following information: (i)
a price per share of common stock, calculated as the sum of the price per share
of General Division Common Stock, par value $.01 per share, of Genzyme ("General
Share"), multiplied by two and the price per share of Tissue Repair Division
Common Stock, par value $.01 per share, of Genzyme ("Tissue Repair Share")
multiplied by 0.135, (ii) an exercise price of the Callable Warrants, calculated
as the 20-day trailing average of the sum of
 
                                       28
<PAGE>   29
 
the price per share of a General Share multiplied by two and the price per share
of a Tissue Repair Share multiplied by 0.135, (iii) an exercise date of the
Callable Warrants of December 31, 1998, (iv) an interest rate of 6.3%, (v)
estimated levels of volatility ranging from 40.9% to 60.9% and (vi) an
adjustment in the price per General Share due to dilution. Robertson, Stephens &
Company computed a per Callable Warrant value ranging from $12.19 to $17.03,
respectively. For purposes of this analysis, Robertson, Stephens & Company noted
that one reliable indicator of the value of the Callable Warrants is the
historical 100-day volatility of the blended General Shares and Tissue Repair
Shares, which is 52.9% and yields an adjusted value per Callable Warrant of
$15.12.
 
  GENERAL
 
     The preparation of fairness opinions involves various determinations as to
the most appropriate and relevant quantitative and qualitative methods of
financial analysis and the application of those methods to the particular
circumstances and, therefore, such opinions are not readily susceptible to
summary description. Accordingly, Robertson, Stephens & Company believes its
analyses must be considered as a whole and that considering any portion of such
analyses and the factors, without considering all such analyses and current
factors, could create a misleading or incomplete view of the process underlying
such opinions. In its analyses, Robertson, Stephens & Company made numerous
assumptions with respect to industry performance, general business and other
conditions and matters, many of which are beyond the control of the Company. Any
estimates contained in these analyses are not necessarily indicative of actual
values or predictive of future results or values, which may be significantly
more or less favorable than as set forth therein. In addition, analyses relating
to the value of a business do not purport to be appraisals or to reflect the
prices at which such businesses actually may be sold.
 
     Robertson, Stephens & Company was engaged on the basis of its experience as
a financial advisor in connection with mergers and acquisitions as well as on
its industry knowledge and familiarity with the Company. Robertson, Stephens &
Company is a nationally recognized investment banking firm. As part of its
investment banking business, Robertson, Stephens & Company is frequently engaged
in the valuation of businesses and their securities in connection with mergers
and acquisitions, negotiated underwritings, secondary distributions of
securities, private placements and other purposes. In the course of its market-
making and other activities, Robertson, Stephens & Company may, from time to
time, have a long or short position in and buy and sell securities of the
Company.
 
     Genzyme has agreed to pay Robertson, Stephens & Company a total fee of
$440,000 for its services as financial advisor to Genzyme and as Dealer Manager.
Of such total fee, $50,000 will be payable upon the purchase of Units pursuant
to the Offer. Genzyme has also agreed to reimburse Robertson, Stephens & Company
for its reasonable out-of-pocket expenses, including the fees and expenses of
its legal counsel. Genzyme has further agreed to indemnify Robertson, Stephens &
Company for certain liabilities relating to or arising out of services provided
by Robertson, Stephens & Company as financial advisor or as Dealer Manager,
including, without limitation, certain liabilities under U.S. federal securities
laws.
 
PURPOSE AND STRUCTURE OF THE TRANSACTION
 
     The purpose of the Offer is to enable Genzyme, through its wholly owned
subsidiary, to acquire the entire equity interest of the Company, and to enable
Genzyme to acquire the Callable Warrants associated with the Units that are
tendered to reduce the possible dilution to Genzyme's existing stockholders.
Following the completion, or under certain circumstances the termination, of the
Offer, Genzyme and the Purchaser intend to acquire any Shares included in the
untendered Units by consummating the Second Step Transaction. In the Second Step
Transaction, holders of Shares included in the untendered Units (other than
Genzyme, the Purchaser or the Company or any direct or indirect subsidiary of
any of them and Holders, if any, who are entitled to and who perfect their
appraisal rights under the applicable provisions of the BVI Law), will receive
$29.00 per Share in cash, without interest. Any Callable Warrants included in
the untendered Units will remain outstanding following the Second Step
Transaction. The acquisition of the Company is structured as a cash tender offer
followed by the Second Step Transaction in order to expedite the opportunity for
Genzyme and the Purchaser to obtain a controlling interest in the Company, to
enable Genzyme to acquire some or all
 
                                       29
<PAGE>   30
 
of the Callable Warrants, to provide a prompt and orderly transfer of ownership
of the Company from the Company's current Holders to the Purchaser and to
provide the Company's current Holders with cash for all of their Units. In the
event that the Minimum Condition is not satisfied, the Purchase Agreement
provides that the Purchaser may elect to amend and extend the Offer to eliminate
this condition. In that event, during the period that the Offer is extended, the
Company shall, in accordance with applicable laws and the Purchase Agreement,
solicit the approval of the holders of the Shares for the Second Step
Transaction. Alternatively, the Purchaser may elect to terminate the Offer and,
promptly thereafter, request that the Company solicit the approval of the
holders of the Shares for the Second Step Transaction. If the Purchaser does not
make either election, Genzyme, the Purchaser or the Company may terminate the
Purchase Agreement. See "SPECIAL FACTORS -- Section 6. The Purchase Agreement;
Appraisal Rights."
 
     Under the BVI Law and the Company's Memorandum and Articles of Association,
if the Purchaser acquires at least a majority of the outstanding Shares, the
Purchaser would have sufficient voting power to approve the Merger Plan, if
necessary, and consummate the Second Step Transaction, by written consent in
lieu of a meeting of the Holders and without the vote or consent of any other
Holders. In addition, under the BVI Law, if the Purchaser acquires at least 90%
of the outstanding Shares, the Purchaser would have the power to consummate a
merger of the Company with and into the Purchaser, or require the Company to
redeem all of the Shares not held by the Purchaser, without a vote of the
Holders. In either event, the Purchaser intends to take all necessary and
appropriate action to cause the Second Step Transaction to become effective as
soon as reasonably practicable after the consummation, or under certain
circumstances the termination, of the Offer without a meeting of the Holders.
 
PLANS FOR THE COMPANY AFTER THE TRANSACTION
 
     Although Genzyme is considering pursuing corporate partnering arrangements
with third parties to jointly develop products based, in part, on technology
owned by the Company, except as described in this Offer to Purchase, neither
Genzyme nor the Purchaser has any present plans or proposals which relate to or
would result in any extraordinary corporate transaction, such as a merger,
reorganization, liquidation, or sale or transfer or a material amount of assets
involving the Company, or any material changes in the Company's capitalization,
dividend policy, corporate structure or business or the composition of the
Company's Board of Directors or management.
 
     The Purchase Agreement provides that, upon the acceptance for payment of
and payment by the Purchaser for any Units pursuant to the Offer, the Purchaser
shall be entitled to designate persons to be elected as Class A directors of the
Company so as to give the Purchaser representation on the Company's Board of
Directors proportional to its ownership of Units. See "SPECIAL
FACTORS -- Section 6. The Purchase Agreement; Appraisal Rights."
 
6.  THE PURCHASE AGREEMENT; APPRAISAL RIGHTS
 
  THE PURCHASE AGREEMENT
 
     The following is a brief summary of certain provisions of the Purchase
Agreement, a copy of which is filed as an exhibit to the Schedule 14D-1 and is
incorporated herein by reference. This summary does not purport to be complete
and is qualified in its entirety by reference to the Purchase Agreement.
Capitalized terms used herein and not otherwise defined have the same meaning as
in the Purchase Agreement.
 
     The Offer.  The Purchase Agreement provides for the commencement of the
Offer as soon as practicable and in any event within five business days of the
public announcement of the Purchaser's intention to make the Offer. The
obligation of the Purchaser to commence the Offer and accept for payment any
Units tendered is subject to the satisfaction of certain conditions (including
the Minimum Condition) which are described in "THE TENDER OFFER -- Section 9.
Certain Conditions of the Offer." The Purchase Agreement provides that without
the consent of the Company, as approved by the Special Committee, the Purchaser
shall not amend or waive the Minimum Condition or the Majority Consent Condition
(as defined below), extend the Offer, reduce the maximum number of Units to be
purchased, reduce the price to be paid per Unit pursuant to the Offer or amend
any other material term of the Offer in a manner adverse to the holders of the
Units.
 
                                       30
<PAGE>   31
 
Pursuant to the Purchase Agreement, if on October 28, 1996 (the "Initial
Expiration Date"), the Minimum Condition has not been satisfied, the Purchaser
may, not later than 9:00 a.m., eastern time, on the next business day following
the Initial Expiration Date, elect either (x) to extend the Offer for a period
not to exceed 60 days and amend the Offer to delete the Minimum Condition and
add the Majority Consent Condition (as defined below), in which case, promptly
thereafter, the Company shall commence to convene a meeting or solicit the
written consent of its shareholders for approval of the Merger Plan (the
foregoing being referred to as the "Simultaneous Solicitation") or (y) terminate
the Offer and promptly return all tendered Units, in which case, promptly
thereafter, the Company shall commence to convene a meeting or solicit the
written consent of its shareholders for approval of the Merger Plan (the
foregoing being referred to as the "Termination Solicitation"), in either case
with such solicitation or meeting to be conducted in accordance with applicable
law and the terms of the Purchase Agreement. The Majority Consent Condition is
defined in the Purchase Agreement to mean that the sum of (a) the Shares
included in the Units tendered and not withdrawn as of the new expiration date
of the Offer (provided such Shares may be voted in favor of the Merger Plan at
the meeting or pursuant to the consent solicitation by the Purchaser immediately
after the purchase of the Units which include such Shares in the Offer by the
Purchaser) plus (b) the number of Shares held by holders who have voted in favor
of the Merger Plan at the meeting or pursuant to the consent solicitation as of
the new expiration date of the Offer (but excluding any such Shares that would
result in double counting with (a) above) represents not less than a majority of
the Shares outstanding.
 
     Approval of the Second Step Transaction.  The Board of Directors of the
Company has authorized the Merger Plan in accordance with applicable law and the
Company's Memorandum and Articles of Association. The Company has agreed in the
Purchase Agreement, at the request of Genzyme, to take all action (coordinating
the timing thereof with Genzyme and the Purchaser) to the extent necessary to
convene a meeting of the Holders as promptly as practicable after the purchase
of Units pursuant to the Offer, if required by applicable law for consummation
of the Second Step Transaction, to consider and vote upon the approval of the
Merger Plan or to solicit the written consent of the Holders to approve the
Merger Plan promptly after such purchase, or at the request of Genzyme, promptly
after the commencement of the Offer and while it is pending upon the election of
Genzyme to pursue the Simultaneous Solicitation or following the termination of
the Offer upon the election of Genzyme to pursue the Termination Solicitation.
If required by applicable law, the Company has agreed to promptly prepare and
file with the Commission, and use its best efforts to have cleared by the
Commission, a proxy, consent solicitation or information statement relating to
the Second Step Transaction in compliance with applicable law.
 
     The Second Step Transaction.  The Purchase Agreement provides that, as soon
as practicable following the consummation of the Offer, the satisfaction of the
Majority Consent Condition (in the event of a Simultaneous Solicitation) or the
satisfaction of the conditions to effect the merger pursuant to the Merger Plan
(in the event of a Termination Solicitation) and subject to the terms and
conditions thereof and the satisfaction or waiver of the other conditions to the
Second Step Transaction and in accordance with the BVI Law, the Purchaser shall
cause to be effected a transaction that results in Genzyme owning, directly or
indirectly, all of the Shares of the Company. If the Offer is consummated and
90% or more of the Units are tendered and accepted, the Purchaser will either
(i) effect a merger of the Company into the Purchaser or (ii) cause the Company
to redeem all Shares included in the untendered Units. If the Offer is
consummated but less than 90% of the Units are tendered and accepted, or if,
pursuant to the Termination Solicitation, the requisite approval of the
Company's shareholders for the Second Step Transaction is obtained, then the
Second Step Transaction will be effected as a merger of the Company with a
wholly owned subsidiary of the Purchaser. Regardless of the form of the Second
Step Transaction, the consideration to be received as a result of the Second
Step Transaction by holders of Shares included in the untendered Units (other
than Genzyme, the Purchaser or the Company or any direct or indirect subsidiary
of any of them and holders, if any, who shall have demanded and perfected their
appraisal rights under the applicable provisions of the BVI Law) will be $29.00
per Share in cash, without interest (the "Second Step Consideration").
 
     Upon consummation of the Second Step Transaction, the Callable Warrants
will become exercisable and, beginning on the day following the Effective Date,
will trade separately from the right to receive the Second Step Consideration on
account of the Callable Common Stock.
 
                                       31

     Indemnification and Insurance.  The Purchase Agreement provides that proper
provision will be made so that any affiliate of Genzyme that succeeds to the
assets and liabilities of the Company or, at Genzyme's option, Genzyme, shall
assume all of the obligations of the Company under the indemnification
agreements between the Company and the members of the Special Committee as in
effect on the date of the Purchase Agreement and, if amended prior to the
Effective Date, on the Effective Date. Genzyme, the Purchaser and the Company
have also agreed that in the event the Company or the successor entity (i)
consolidates with or merges into any other person and shall not be the surviving
corporation or (ii) transfers all or substantially all of its assets to any
person, then, and in each case, proper provision shall be made so that the
successors and assigns of such successor entity or at Genzyme's option, Genzyme,
shall assume the indemnity obligations under such agreements. The Purchase
Agreement also provides that the Company, and from and after the consummation of
the Offer (or the Merger in the event of the Termination Solicitation) Genzyme,
shall, to the fullest extent permitted by applicable law, indemnify and hold
harmless each present and former director or officer of the Company against all
losses arising out of any act or omission in their capacity as an officer,
director or employee of the Company. Additionally, Genzyme is obligated to
maintain, for three years from the Effective Date, directors' and officers'
liability insurance policies covering the directors and officers of the Company
with coverages and other terms at least as favorable as is currently in effect;
provided that Genzyme is not obligated to spend more than 150% of the current
annual premiums paid by the Company for such insurance, and, following such
three year period until the sixth anniversary of the Effective Date, Genzyme has
agreed to assume the indemnification obligations of the Company under the
indemnification agreements referred to above to the extent that it has not
already done so.
 
     Designation of Directors.  The Purchase Agreement provides that, promptly
upon the acceptance for payment of and payment by the Purchaser for any Units
pursuant to the Offer, and from time to time thereafter as Units are accepted
for payment and paid for by the Purchaser, the Purchaser shall be entitled to
designate such number of Class A directors of the Company, rounded to the
nearest whole number, as will give the Purchaser representation on the Company's
Board of Directors equal to at least that number of directors which equals the
product of the total number of the Company's directors (after giving effect to
the directors elected in accordance with this procedure) multiplied by the
percentage that such number of Units so accepted for payment and paid for by the
Purchaser bears to the number of Units outstanding, and the Company shall, at
such time, take such actions as are necessary to cause the Purchaser's designees
to be so elected or appointed; provided, however, that, notwithstanding the
Purchaser's right to designate certain of the Company's directors as described
above, until the Effective Date, the Company's Class A Directors shall include
at least two directors who were directors on September 20, 1996 and who are not
officers or directors of Genzyme or the Purchaser (the "Independent Directors");
provided further, that, if the number of Independent Directors shall be reduced
below two for any reason whatsoever, any remaining Independent Director shall be
entitled to designate a person who is not an officer or director of Genzyme or
the Purchaser to fill such vacancy who shall be deemed to be an Independent
Director or, if no Independent Directors then remain, the other directors shall
designate two persons to fill such vacancies who shall not be designees,
stockholders, directors, officers or affiliates of Genzyme or the Purchaser, and
such persons shall be deemed to be Independent Directors.
 
     Notwithstanding anything in the Purchase Agreement to the contrary, subject
to the terms of the Company's Memorandum of Association and Articles of
Association, in the event that the Purchaser's designees are appointed or
elected as the Company's directors, after the acceptance for payment of Units
pursuant to the Offer and prior to the Effective Date, the affirmative vote of a
majority (or, if there are only one or two Independent Directors, the single or
unanimous vote, as the case may be) of the Independent Directors (who shall act
as an independent committee of the Board of Directors for this purpose) shall be
required, and alone shall be sufficient, to (i) amend or terminate the Purchase
Agreement by the Company, (ii) exercise or waive any of the Company's rights or
remedies under the Purchase Agreement, (iii) extend the time for performance of
Genzyme's and the Purchaser's respective obligations under the Purchase
Agreement, or (iv) approve any other action by the Company that the Independent
Directors determine could adversely affect the interests of the Holders (other
than Genzyme, the Purchaser and their affiliates) with respect to the
transactions contemplated by the Purchase Agreement.

     Representations and Warranties.  The Purchase Agreement contains certain
customary representations and warranties of the parties. The Company has made
representations and warranties to Genzyme and the Purchaser regarding, among
other things: (i) the Company's organization and qualification; (ii) the
Company's capitalization; (iii) the Company's authority to enter into and
perform its obligations under the Purchase Agreement (subject to approval of the
Merger Plan by the shareholders to the extent required by the BVI Law); (iv) the
compliance of the transactions contemplated by the Purchase Agreement with the
Company's Memorandum of Association and Articles of Association, certain
agreements and applicable laws; and (v) the accuracy and completeness of the
Company's Schedule 14D-9 filed in connection with the Offer and any proxy or
information statement to be filed in connection with the Second Step
Transaction.
 
     Genzyme and the Purchaser have made representations and warranties to the
Company regarding, among other things: (i) Genzyme's and the Purchaser's
organization and qualification; (ii) Genzyme's and the Purchaser's authority to
enter into and perform their respective obligations under the Purchase
Agreement; (iii) the compliance of the transactions contemplated by the Purchase
Agreement with Genzyme's and the Purchaser's respective charters or other
governing instruments, certain agreements and applicable laws; and (iv) the
accuracy and completeness of the documents filed by Genzyme and the Purchaser
with the Commission in connection with the Offer.
 
     The representations and warranties contained in the Purchase Agreement
shall expire upon consummation of the Offer.
 
     Conditions to the Second Step Transaction.  The obligations of each of the
Company, the Purchaser and Genzyme to consummate the Second Step Transaction,
other than following a Termination Solicitation, are subject to the following
conditions: (i) the Purchaser shall have made the Offer on the terms and
conditions set forth therein and shall have purchased, or caused to be
purchased, all Units validly tendered and not withdrawn pursuant to the Offer;
provided, however, that this condition is not applicable to the obligations of
Genzyme or the Purchaser if, in breach of the Purchase Agreement or the terms of
the Offer, the Purchaser fails to purchase any Units validly tendered and not
withdrawn pursuant to the Offer; (ii) the Merger Plan shall have been approved
and adopted by the requisite vote or consent of the Holders, if any, required by
the BVI Law and the Company's Memorandum of Association and Articles of
Association; and (iii) no preliminary or permanent injunction or other order,
decree or ruling issued by a court of competent jurisdiction or by a
governmental, regulatory or administrative agency or commission nor any statute,
rule, regulation or executive order promulgated or enacted by any governmental
authority shall be in effect, which would make the acquisition by Genzyme or the
Purchaser of the Callable Common Stock illegal or otherwise prevent the
consummation of the Second Step Transaction. In addition to the condition set
forth in clause (ii) of the preceding sentence, following a Termination
Solicitation in which clause (ii) of the preceding sentence has been satisfied,
the Purchaser shall not be obligated to effect a merger pursuant to the Merger
Plan if on or before the Effective Date any of the following shall occur or
shall be determined by the Purchaser to have occurred and remain in effect:
 
     (a) except for matters which affect generally the economy or the industry
in which the Company is engaged and except for continued losses incurred by the
Company as a result of its operations and continued depletion of its cash
resources in the ordinary course of business or consistent with the annual
workplan currently in effect, any change shall have occurred in the business,
properties, assets, liabilities, capitalization, shareholders equity, financial
condition, operations, licenses or franchises or results of operations of the
Company which has a Material Adverse Effect (as defined in the Purchase
Agreement); or
 
     (b) there shall have been instituted or be pending any action, proceeding,
application or counterclaim before any court or governmental or regulatory body
which (i) challenges the validity of or seeks to restrain the consummation of or
to impose any material limitation, on any transaction contemplated by the
Purchase Agreement or seeks (ii) to obtain any material amount of damages in
connection with such transactions; or
 
     (c) any statute, regulation, order or injunction shall have been enacted,
entered, enforced or deemed applicable to the Merger that is reasonably likely
to, directly or indirectly, result in any of the consequences referred to in
paragraph (b) above; or
 
                                       33
<PAGE>   34
 
     (d) the representations and warranties of the Company set forth in the
Purchase Agreement shall not be true in any material respect as though made on
such date, or the Company shall have failed in any material respect to perform
any material obligation or covenant required in the Purchase Agreement to be
performed or complied with by it; or
 
     (e) the Company shall have entered into, or shall have publicly announced
its intention to enter into, an agreement or agreement in principle with respect
to any Acquisition Proposal (as defined below).
 
     Acquisition Proposals.  The Company has agreed in the Purchase Agreement
that it shall not, directly or indirectly through any officer, director,
employee, financial advisor, representative or agent of the Company: (i) solicit
or initiate any inquiries or proposals for a merger, consolidation, business
combination, sale of substantial assets, sale of shares of capital stock
(including without limitation by way of a tender offer) or similar transactions
involving the Company, other than the transactions contemplated by the Purchase
Agreement (any of the foregoing inquiries or proposals being referred to as an
"Acquisition Proposal"); (ii) engage in negotiations or discussions concerning,
or provide any non-public information to any person or entity relating to, any
Acquisition Proposal; or (iii) agree to, approve or recommend any Acquisition
Proposal; provided, however, that nothing contained in the Purchase Agreement
shall prevent the Company, the Company's directors or the Special Committee
(through any officer, director, employee, financial advisor, representative or
agent) from (A) engaging in negotiations or discussions in response to an
inquiry that was not solicited after September 20, 1996; (B) furnishing
non-public information to any person or entity in connection with an unsolicited
written Acquisition Proposal by such person or entity or recommending an
unsolicited written Acquisition Proposal to the Holders, if and only to the
extent that (1) the Company's Board of Directors or the Special Committee, as
the case may be, believe in good faith (after consultation with its financial
advisor) that the party requesting such non-public information is capable of
financing a transaction more favorable to the Holders from a financial point of
view than the transaction contemplated by the Purchase Agreement and the
Company's Board of Directors or the Special Committee, as the case may be,
determine in good faith (after consultation with outside legal counsel) that
such action is necessary to comply with their fiduciary duties to Holders under
applicable law and (2) prior to furnishing such non-public information to such
person or entity, the Company's Board of Directors or the Special Committee, as
the case may be, receive from such person or entity an executed confidentiality
agreement on customary terms or (C) complying with Rule 14e-2 promulgated under
the Exchange Act with regard to an Acquisition Proposal.
 
     The Company has further agreed that it will notify Genzyme in writing
within 24 hours after receipt by the Company (or its advisors) of any written
Acquisition Proposal or any written request for non-public information pursuant
to which it intends to provide non-public information.
 
     Conduct of Business.  Pursuant to the Purchase Agreement the Company has
agreed that, except as otherwise expressly contemplated thereby, prior to the
Effective Date or such earlier time as designees of the Purchaser constitute a
majority of the Company's Directors (determined on the basis of the combined
voting power of the Company's Class A and Class B Directors): (a) the business
of the Company shall in all material respects be conducted only in, and the
Company shall not take any material action except in, the ordinary course of
business and consistent with past practice, and the Company shall use all
reasonable efforts, consistent with past practice or the annual workplan
currently in effect, to maintain and preserve its business organization, assets,
and advantageous business relationships; (b) the Company shall not make any tax
election or, except in the ordinary course of business and consistent with past
practice, settle or compromise any federal, state, local or foreign tax
liability; and (c) the Company shall not agree, in writing or otherwise, to take
any of the foregoing actions or any action which would make any representation
or warranty of the Company in the Purchase Agreement untrue or incorrect in any
material respect, or which would materially impair or prevent the occurrence of
any condition described in "THE TENDER OFFER -- Section 9. Certain Conditions to
the Offer" prior to the consummation of the Offer.
 
     In addition to the foregoing, the Purchase Agreement provides that, if the
Minimum Condition has not been satisfied on the Initial Expiration Date, and the
Purchaser elects to proceed with either a Simultaneous Solicitation or a
Termination Solicitation, then until the earlier of the Effective Date or the
termination of the Purchase Agreement, the Special Committee shall be authorized
to take such actions as it may deem
 
                                       34
<PAGE>   35
 
appropriate to reduce or eliminate any discretionary spending by the Company or
by Genzyme on behalf of the Company not contractually committed to with a person
or entity that is not a party to the Purchase Agreement; provided that, Genzyme
may elect to continue such spending on its own account and to the extent it
elects to do so, the Company will, if the Merger is effected, reimburse Genzyme
for such expenditures immediately prior to the Effective Date.
 
     Fees and Expenses.  The Purchase Agreement provides that each party thereto
shall bear all of the fees and expenses incurred by it in connection with the
negotiation and performance of the Purchase Agreement and no party to the
Purchase Agreement may recover any such fees and expenses from another party
upon termination of the Purchase Agreement, except for a termination fee payable
to Genzyme as further described under the heading "Effect of Termination
Resulting from a Superior Transaction."
 
     Termination.  The Purchase Agreement may be terminated at any time prior to
the Effective Date as follows:
 
          (a) by the mutual written consent of the Boards of Directors of
     Genzyme, the Purchaser and the Company, with the affirmative vote of a
     majority of the Independent Directors (who shall act as an independent
     committee of the Board of Directors of the Company for this purpose) being
     required, and alone being sufficient, for action by the Board of Directors
     of the Company for this purpose;
 
          (b) by the Company upon approval of the Special Committee: (i) if (A)
     the Purchaser shall have terminated the Offer without the purchase of any
     Units thereunder; or (B) the Purchaser shall not have paid for all Units
     validly tendered pursuant to the Offer and not withdrawn within 90 days
     after the commencement of the Offer, unless such termination of the Offer
     or failure to pay for Units shall have been caused by or resulted from the
     failure of the Company to perform in any material respect any of its
     covenants or agreements contained in the Purchase Agreement, the material
     breach by the Company of any of its representations or warranties contained
     in the Purchase Agreement or an election by the Purchaser to terminate the
     Offer and effect a Termination Solicitation; or (ii) if the Effective Date
     shall not have occurred on or before the six-month anniversary of the
     execution of the Purchase Agreement due to a failure of any of the
     conditions to the obligation of the Company to effect the Second Step
     Transaction as described above under the heading Conditions to the Second
     Step Transaction, or if the Purchaser has elected to proceed with the
     Termination Solicitation, if the Effective Date shall not have occurred on
     or before the six-month anniversary of the date of the Purchase Agreement;
     or (iii) if, prior to the purchase of any Units pursuant to the Offer, or
     the Effective Date if the Purchaser has elected to proceed with a
     Termination Solicitation, Genzyme or the Purchaser materially fails to
     perform any of their respective obligations under the Purchase Agreement
     and such nonperformance has a material adverse effect on Genzyme's or the
     Purchaser's ability to consummate the Offer or the Second Step Transaction;
     or (iv) if, in the event the Minimum Condition shall not have been
     satisfied on the Initial Expiration Date and the Purchaser shall have
     amended the Offer or terminated the Offer pursuant to its election to
     proceed with either the Simultaneous Solicitation or the Termination
     Solicitation, the Purchaser has materially failed to perform any of its
     obligation in connection with the Simultaneous or Termination Solicitation;
     or (v) if, prior to the purchase of Units pursuant to the Offer, or the
     Effective Date if the Purchaser has elected to proceed with the Termination
     Solicitation, the Special Committee shall have withdrawn or modified its
     approval or recommendation of the Offer or the Purchase Agreement in order
     to approve the execution by the Company of a definitive agreement providing
     for the acquisition of the Company or substantially all of its assets or a
     merger or other business combination or in order to approve a tender offer
     for all of the Shares or Units by a third party, in any case, as determined
     by the Special Committee, on terms more favorable to the Company's
     shareholders than the Offer (a "Superior Transaction"), provided, that (i)
     the Company shall have provided Genzyme with at least five business days'
     written notice of such Superior Transaction, including a copy of the
     proposed agreement and (ii) the Company shall not have violated the
     provisions described above under "Acquisition Proposals"; or
 
          (c) by Genzyme or the Purchaser (i) if, due to an occurrence that
     would result in a failure to satisfy any condition to the consummation of
     the Offer or the Majority Consent Condition if the Purchaser has
 
                                       35
<PAGE>   36
 
     elected to proceed with the Simultaneous Solicitation, the Purchaser shall
     have (A) failed to commence the Offer within 5 business days of the date on
     which the Purchaser's intention to make the Offer is publicly announced;
     (B) terminated the Offer without the purchase of any Units thereunder; or
     (C) failed to pay for all Units validly tendered pursuant to the Offer and
     not withdrawn within 90 days after commencement of the Offer, unless such
     failure or termination shall have been caused by or results from (x) the
     failure of Genzyme or the Purchaser to perform in any material respect any
     of its covenants or agreements contained in the Purchase Agreement, (y) the
     material breach by Genzyme or the Purchaser of any of its representations
     or warranties contained in the Purchase Agreement, or (z) the Purchaser's
     election to proceed to seek approval of the Merger Plan pursuant to the
     Termination Solicitation; or (ii) if the Effective Date shall not have
     occurred on or before the six-month anniversary of the date of the Purchase
     Agreement due to a failure of any of the conditions to the obligations of
     Genzyme or the Purchaser to effect the Second Step Transaction as described
     above under the heading "Conditions to the Second Step Transaction"; or
     (iii) if, prior to the purchase of Units pursuant to the Offer, or the
     Effective Date if the Purchaser has elected to proceed with the Termination
     Solicitation, the Company's directors shall have publicly withdrawn or
     modified in a manner adverse to the Purchaser their approval or
     recommendation of the Offer or the Purchase Agreement or recommended
     acceptance of a Superior Transaction or shall have resolved to do any of
     the foregoing.
 
     Effect of Termination.  In the event of the termination of the Purchase
Agreement as provided under the heading "Termination," all obligations and
agreements of the parties set forth therein shall forthwith terminate and be of
no further force or effect, and there shall be no liability on the part of
Genzyme, the Purchaser or the Company thereunder except (a) as provided under
the headings "Effect of Termination Resulting from a Superior Transaction" and
"Ancillary Agreements" below and (b) that the foregoing shall not relieve any
party for liability for any breach of the Purchase Agreement occurring prior to
such termination.
 
     Effect of Termination Resulting from a Superior Transaction.  In the event
of the termination of the Purchase Agreement by the Company in accordance with
clause (b)(v) under the heading "Termination" or by Genzyme or the Purchaser in
accordance with (x) clause (c)(iii) under the heading "Termination", or (y)
clause (c)(i) or (c)(ii) under the heading "Termination" if such termination is
based on the failure of the Company to perform in any material respect any of
its covenants or agreements contained in the Purchase Agreement, the Purchase
Agreement requires that the Company pay to Genzyme a termination fee of $500,000
upon consummation of any Superior Transaction.
 
     Ancillary Agreements.  In the event of any termination of the Purchase
Agreement (x) by the Company in accordance with clause (b)(v) or by Genzyme or
the Purchaser in accordance with clause (c)(iii) under the heading "Termination"
above as a result of a Superior Transaction in connection with which the Company
shall not have violated the provisions described above under the heading
"Acquisition Proposals,", or (y) by Genzyme or the Purchaser pursuant to clause
(c)(i) under the heading "Termination" above, unless such termination is based
on the failure of the Company to perform in any material respect any of its
covenants or agreements contained in the Purchase Agreement, Genzyme has agreed
that, effective upon consummation of such Superior Transaction, it shall, at the
Company's request, (a) consent to the Superior Transaction in its capacity as
holder of the Company's Series 1992 Note and pursuant to all applicable
provisions of the Company's Memorandum of Association; (b) terminate the
Purchase Option Agreement, in which event the Series 1992 Note will become due
and payable in accordance with its terms; (c) consent to the assignment by the
Company of the Technology License Agreement; (d) at the option of Genzyme,
terminate or consent to the assignment by the Company of each of the Research
and Development Agreement, the Services Agreement, and the Administrative
Agreement.
 
     Amendment.  Subject to the amendment provision described above under the
heading "Designation of Directors," the Purchase Agreement may not be amended
except by action of the Boards of Directors of each of the parties to the
Purchase Agreement, set forth in an instrument in writing signed on behalf of
each of the parties; provided, however, that the Board of Directors of the
Company shall not act to amend the Purchase Agreement without the approval of
the Special Committee.
 
                                       36
<PAGE>   37
 
     Waiver.  At any time prior to the Effective Date, whether before or after
any special meeting or written action of the Holders to approve the Second Step
Transaction, any party to the Purchase Agreement, subject to the waiver
provisions described above under the heading "Designation of Directors," by
action taken by its Board of Directors (and in the case of the Company, subject
to the approval of the Special Committee), may (i) extend the time for the
performance of any of the obligations or other acts of any other party to the
Purchase Agreement or (ii) subject to the third sentence above under the heading
"The Offer" and the proviso contained above under the heading "Amendment," waive
compliance with any of the agreements of any other party or with any conditions
to its own obligations. Any agreement on the part of a party to the Purchase
Agreement to any such extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party by a duly authorized
officer.
 
  APPRAISAL RIGHTS
 
     No appraisal rights are available in connection with the Offer. However, if
the Second Step Transaction is consummated, Holders may have certain rights
under Section 83 of the BVI Law to dissent and demand appraisal of, and to
receive payment in cash of the fair value of, their Shares. Under the BVI Law,
holders of shares of a BVI company are entitled to payment of fair value for
their shares upon dissenting from mergers (if the BVI company is a constituent
company in the merger and not the surviving company), consolidations, certain
dispositions of more than 50% of the company's assets, compulsory redemptions of
shares, and certain other transactions (a "Specified Transaction"). In order to
assert rights under Section 83, the following procedures must be followed:
 
        - A Holder who desires to exercise dissenters' rights must give to the
          Company before or at the meeting of Holders at which the Specified
          Transaction is submitted to a vote, a written notice of an objection
          to the Specified Transaction. The objection must include a statement
          that the Holder proposes to demand payment for his shares if the
          action is taken. In the event that the Holder does not receive notice
          of the meeting, or if the proposed action is authorized by written
          consent without a meeting, no notice of objection is required.
 
        - Within 20 days following the authorization of the Specified
          Transaction by vote or written consent, the Company must give written
          notice of the action to each Holder who gave written objection or from
          whom written objection was not required, except those who voted for,
          or consented in writing to, the proposed action. A Holder to whom the
          Company is required to give notice who elects to dissent must, within
          20 days of notice or authorization, give to the Company a written
          notice of his decision to elect to dissent, stating such Holder's name
          and address, the number and class or series of shares involved (which
          must include all shares held by such Holder) and a demand for payment
          of fair value for the shares. Upon the giving of notice, the Holder
          ceases to have the rights of a Holder with the exception of the right
          to be paid for the fair value of his shares.
 
        - Within 7 days of the later to occur of: (i) the expiration of the
          period within which Holders may give notice or election of dissent or
          (ii) the effective date of the Specified Transaction, the surviving
          corporation must make a written offer to each dissenting Holder to
          purchase his shares at a price that the Company determines to be their
          fair value.
 
        - If within 30 days of the offer, the Company and the dissenting Holder
          agree on the price to be paid for the shares, the Company will pay
          such amount to the Holder upon surrender of the certificates
          representing the shares.
 
        - If the Company and the dissenting Holder fail to agree on a price
          within 30 days, the following shall occur within the next 20 days:
 
             (i) the Company and the Holder shall each designate an appraiser;
 
             (ii) the two designated appraisers shall designate a third
        appraiser;
 
                                       37
<PAGE>   38
 
             (iii) the three appraisers shall fix the fair value of the
        dissenting Holders' shares as of the close of business on the day prior
        to the vote on the Specified Transaction, excluding any appreciation or
        depreciation directly or indirectly induced by the Specified
        Transaction, and such value shall be binding on the Company and the
        dissenter; and
 
             (iv) the Company shall pay the dissenting Holder such amount in
        money upon the surrender of the certificates representing the shares.
 
        - The enforcement by a Holder of dissenters' rights will exclude the
          enforcement by the Holder of his other rights as a holder of shares,
          other than the Holder's right to obtain relief on the ground that the
          action taken was illegal.
 
     See Annex II attached hereto for the full text of Section 83 of the BVI
Law.
 
7.  CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     THE FOLLOWING IS A SUMMARY OF THE MATERIAL UNITED STATES FEDERAL INCOME TAX
CONSEQUENCES TO HOLDERS OF THE TRANSACTIONS DESCRIBED IN THIS OFFER TO PURCHASE.
THE TAX CONSEQUENCES OF THE TRANSACTIONS WILL DEPEND IN LARGE PART ON THE FACTS
AND CIRCUMSTANCES APPLICABLE TO EACH HOLDER. THEREFORE, EACH HOLDER IS URGED TO
CONSULT THE HOLDER'S OWN TAX ADVISORS REGARDING THE UNITED STATES FEDERAL INCOME
TAX CONSEQUENCES TO THAT HOLDER. NO INFORMATION IS PROVIDED WITH RESPECT TO
STATE, LOCAL, OR FOREIGN TAX CONSEQUENCES, AND HOLDERS ARE URGED TO CONSULT
THEIR OWN TAX ADVISORS WITH RESPECT TO SUCH CONSEQUENCES.
 
     The discussion does not address federal income tax consequences applicable
to all Holders, some of whom may be subject to special rules (including, for
example, Holders who own, or are considered as owning pursuant to certain
attribution rules, five percent or more of the outstanding Shares). The
discussion focuses on Holders who are individual citizens or residents of the
United States and domestic corporations and has only limited application to
Holders who are foreign corporations, regulated investment companies, life
insurance companies, financial institutions, estates, trusts, tax-exempt
organizations or nonresident aliens. Also, unless otherwise stated, the
discussion assumes that each of the Units, Shares and Callable Warrants are
capital assets in the hands of the Holder at all relevant times.
 
     The discussion is based upon existing federal income tax law, including the
Internal Revenue Code of 1986, as amended (the "Code"), income tax regulations
issued by the Internal Revenue Service (the "IRS"), rulings of the IRS and court
decisions. Future changes in the federal income tax laws could adversely affect
a Holder.
 
CONSEQUENCES OF PASSIVE FOREIGN INVESTMENT COMPANY STATUS
 
     In each year that Neozyme II has been in existence, Neozyme II has
determined that it qualified as a Passive Foreign Investment Company ("PFIC")
and has sent to the holders of the Units the PFIC annual information statement
and a form of an election statement whereby the shareholder could elect to treat
Neozyme II as a qualified electing fund ("QEF") and to include annually in gross
income the shareholder's pro rata share of Neozyme II's ordinary earnings and
net capital gain (his "QEF inclusion").
 
     If a Holder has not elected to treat Neozyme II as a QEF, any gain
recognized by such non-electing Holder as a result of the disposition of the
Holder's Shares pursuant to the transactions described in this Offer to Purchase
will be treated as ordinary income. The non-electing Holder's tax liability with
respect to such gain will be determined by allocating such gain in pro rata
amounts to each day in the Holder's holding period for the Shares and by
multiplying the gain allocated to each taxable year of the Holder other than the
current taxable year by the highest rate of tax in effect for the Holder in that
year, without regard to the actual rate that applied to the Holder's income in
that year. The non-electing Holder will be subject to an interest charge on the
taxes so determined at the rates and using the methods in Section 6621 of the
Code for underpayments of tax, as if the Holder had recognized the gain
allocated to each prior taxable year in that prior taxable year.
 
     If a Holder elected to treat Neozyme II as a QEF in the first taxable year
that the Holder held Shares or later made the election and also either (i)
elected to treat the Shares generally as if they were sold on the first day of
the taxable year for which the election was made or (ii) elected to include in
the Holder's gross income
 
                                       38
<PAGE>   39
 
the earnings and profits attributable to the Shares as of the first day of the
taxable year for which the election was made, any gain recognized by such
electing Holder as a result of the disposition of the Holder's Shares pursuant
to the transactions described in this Offer to Purchase will generally be
capital gain if the stock is held as a capital asset on the disposition date.
 
     If for any taxable year an electing Holder elected under Section 1294 of
the Code to extend the time for the payment of the tax on a QEF inclusion and
that extension has not expired, the disposition of the Holder's Shares pursuant
to the transactions described in this Offer to Purchase will cause the extension
to expire. The extension will expire on the due date (without regard to
extensions) of the Holder's tax return for the taxable year in which the
disposition occurs.
 
     Following the consummation of the transactions described in this Offer to
Purchase, Genzyme may make an election pursuant to Section 338 of the Code. Such
an election may cause an electing Holder to recognize a substantially increased
QEF inclusion. However, the basis of the electing Holder's Shares should be
increased by the amount of the QEF inclusion. Any additional amounts of net
capital gain QEF inclusion resulting from the Section 338 election should thus
be offset by a reduced amount of capital gain or a capital loss in respect of
the electing Holder's sale of the Shares. However, any additional amounts of
ordinary earnings QEF inclusion resulting from the Section 338 election could
not generally be offset by a capital loss (except possibly for certain
relatively small amounts in the case of individuals).
 
CONSEQUENCES TO HOLDERS WHOSE UNITS ARE TENDERED AND ACCEPTED PURSUANT TO THE
TENDER OFFER
 
     A Holder who tenders a Unit pursuant to the Offer and does not properly
withdraw such Unit prior to the expiration of the Offer will be deemed to have
sold each of the Unit's constituent elements, i.e., one share of Callable Common
Stock and one Callable Warrant, for the Offer Price and will be required to
allocate the Offer Price between these constituent elements in proportion to
their relative fair market values on the purchase date.
 
     The Holder will recognize gain or loss with respect to the deemed sale of
the Callable Warrant in an amount equal to the difference between the amount of
the Offer Price allocable to the Callable Warrant and the portion of the
Holder's adjusted basis in the Unit allocable to the Callable Warrant. This gain
or loss will generally be capital gain or loss if the Unit is held as a capital
asset on the purchase date and will be long-term capital gain or loss if the
Unit has been held for more than one year on the purchase date.
 
     The Holder will recognize gain or loss with respect to the deemed sale of
the share of Callable Common Stock in an amount equal to the difference between
the amount of the purchase price of the Unit allocable to the share of Callable
Common Stock and the portion of the Holder's adjusted basis in the Unit
allocable to the share of Callable Common Stock. Except as otherwise described
above under Consequences of Passive Foreign Investment Company Status, this gain
or loss will generally be capital gain or loss if the Unit is held as a capital
asset on the purchase date and will be long-term capital gain or loss if the
Unit has been held for more than one year on the purchase date.
 
CONSEQUENCES TO HOLDERS WHO DO NOT TENDER THEIR UNITS
 
     If the Offer is consummated, Genzyme intends to effect the Second Step
Transaction, pursuant to which all of the Shares included in untendered Units
will be converted into the right to receive cash in an amount per Share equal to
the Second Step Consideration. The Callable Warrants associated with these
Shares will become exercisable and will separate and be transferable separately
from the right to receive cash for the Shares.
 
     A Holder whose Shares are converted to the right to receive cash in the
Second Step Transaction will recognize gain or loss in an amount equal to the
difference between the Second Step Consideration and the portion of the Holder's
adjusted basis in the Unit allocable to the Shares. Except as otherwise
described above under Consequences of Passive Foreign Investment Company Status,
this gain or loss will generally be capital gain or loss if the Unit is held as
a capital asset on the Effective Date and will be long-term capital gain or loss
if the Unit has been held for more than one year on the Effective Date.
 
                                       39
<PAGE>   40
 
     A Holder will not recognize income, gain or loss as a result of the
acceleration in the exercisability of the Callable Warrants or their separation
from the Shares.
 
OTHER CONSIDERATIONS
 
     Uncertainty exists as to the treatment of the initial grant to Genzyme of
the Purchase Option. The IRS might take the position that the Callable Warrants
received as part of a Unit in the initial Unit Offering in April 1992 were
issued by Genzyme in exchange for the separate grant of the Purchase Option by
the initial purchasers of the Units and that the full purchase price of the
Units was paid in exchange for the Callable Common Stock. In that event, upon
the lapse or termination of the Purchase Option, a Holder might recognize a
short-term capital gain in an amount equal to the value of the Callable Warrants
on the closing date of the initial Unit Offering, less the Holder's tax basis in
the Callable Warrants.
 
     If a Holder were treated as having paid the full purchase price for the
Unit in exchange for the Callable Common Stock and as then having granted the
Purchase Option to Genzyme in exchange for the Warrants, the Holder would have
an increased tax basis in the Callable Common Stock which would reduce the
amount of gain (or increase the amount of loss) realized upon a disposition of
the Callable Common Stock pursuant to the transactions described in this Offer
to Purchase. Any such loss would be available to offset any gain taken into
account from a lapse or termination of the Purchase Option.
 
  United States Taxation of Non-U.S. Persons
 
     The following is a general discussion of certain anticipated United States
federal income tax consequences of a disposition of Units or Shares to a Holder
who, for United States federal income tax purposes, (1) is not a "United States
person", (2) is not, and has not been, engaged in a United States trade or
business and (3) in the case of an individual, will not be present in the United
States for 183 days or more during the taxable year of the Holder that includes
the date of disposition of the Holder's Units or Shares. A "United States
person" means a citizen or resident of the United States for United States
federal income tax purposes, a corporation, partnership or other entity created
or organized in or under the laws of the United States or any state thereof, or
an estate or trust, the income of which is subject to United States federal
income tax regardless of its sources. The following discussion does not consider
specific facts and circumstances that may be relevant to a particular Non-U.S.
Holder's tax position. Specifically, this discussion does not address the United
States tax consequences to any person who might own, or be considered as owning
pursuant to certain attribution rules, 5 percent or more of the outstanding
Shares. Furthermore, the following discussion is based on current provisions of
the Code and on administrative and judicial interpretations as of the date
hereof, all of which are subject to change. Each Non-U.S. Holder, as well as
each non-United States person who is or has been engaged in a United States
trade or business or who is an individual who has been present in the United
States for 183 days or more during a taxable year, or who may be eligible for
special treatment under an applicable income tax treaty is urged to consult a
tax advisor with respect to the United States federal income tax consequences of
the disposition of Units or Shares, as well as any tax consequences that may
arise under the laws of any foreign, state, local or other taxing jurisdiction.
 
     A Non-U.S. Holder will not be subject to United States federal income tax
(and no tax will generally be withheld) with respect to gain recognized on a
disposition of the Units or of Callable Common Stock. Backup withholding
requirements may apply to the gross proceeds paid to a Non-U.S. Holder upon the
disposition of the Units or Shares, unless the holder certifies its foreign
status or otherwise establishes an exemption. A Non-U.S. Holder may obtain a
refund of any amounts withheld under the backup withholding rules by filing the
appropriate claim for refund with the Internal Revenue Service.
 
8.  CERTAIN EFFECTS OF THE TRANSACTION
 
     Interest in Assets and Earnings.  Neither Genzyme or the Purchaser
currently owns any of the outstanding Units. As a result of the Offer and the
Second Step Transaction, Genzyme (directly or indirectly through the Purchaser)
will own the entire equity interest in the Company and will thereby be entitled
to 100% of the Company's net assets and earnings and the current Holders will no
longer have an equity interest in the Company.
 
                                       40
<PAGE>   41
 
     Voting Power.  Unless waived by Genzyme and the Purchaser, the Offer is
conditioned upon the tender of at least a majority of the outstanding Units. If
a majority of the outstanding Units are tendered in the Offer, the Purchaser
will have the right under the BVI Law and the Company's Memorandum of
Association and Articles of Association to approve the Second Step Transaction
by written consent in lieu of a meeting of stockholders and without the vote or
consent of any of the remaining Holders. In addition, under the BVI Law, if the
Purchaser acquires at least 90% of the outstanding Units, the Purchaser would
have the power to approve a merger of the Company into the Purchaser, or require
the Company to redeem all of the Shares not held by the Purchaser, in each case
without a vote of the Holders.
 
     NNM Quotation.  Depending upon the aggregate market value and the number of
Units not purchased pursuant to the Offer, as well as the identity of the
holders of such Units, the Units may no longer meet the quantitative
requirements of the National Association of Securities Dealers, Inc. the
("NASD") for continued inclusion in the NNM, which require that an issuer have
at least 200,000 publicly held shares, held by at least 400 stockholders or 300
stockholders of round lots, with a market value of at least $1 million, have net
tangible assets of at least $1 million, $2 million or $4 million (depending on
profitability levels during the issuer's four most recent fiscal years) and have
a minimum bid price per shares of $1 (unless the issuer has a public float of at
least $3 million and at least $4 million of net tangible assets).
 
     In the event that the Units no longer meet the requirements for NNM
quotation, it is possible that the Units would continue to trade in the
over-the-counter market and that price or other quotations might still be
available from other sources. The extent of the public market for the Units and
the availability of such quotations would, however, depend upon such factors as
the number of holders and/or the aggregate market value of such Units remaining
at such time, the interest in maintaining a market in such Units on the part of
securities firms, the possible termination of registration of such Units under
the Exchange Act, as described below, and other factors. The Purchaser cannot
predict whether a reduction in the number of Units that might otherwise trade
publicly would have an adverse or beneficial effect on the market price for or
marketability of the Units or whether it would cause future market prices to be
greater or less than the price to be paid in the Offer.
 
     The Purchaser and Genzyme intend to cancel all Callable Warrants purchased
by the Purchaser pursuant to the Offer. Following the Second Step Transaction,
Genzyme does not intend to list the outstanding Callable Warrants on the NNM,
and therefore, any market that may develop for the Callable Warrants may be
adversely affected.
 
     Exchange Act Registration.  The Units are currently registered under the
Exchange Act. The purchase of Units pursuant to the Offer or following
consummation of the Offer may result in the Units becoming eligible for
deregistration under the Exchange Act. Registration of the Units may be
terminated upon application of the Company to the Commission if the Units are
not listed on a national securities exchange and there are fewer than 300 record
holders of the Units. There currently are fewer than 300 record holders of the
Units. The termination of the registration of the Units under the Exchange Act,
assuming there are no other securities of the Company subject to registration,
would result in the suspension of the Company's obligation to file reports
pursuant to Section 15(d) of the Exchange Act, thereby substantially reducing
the information required to be furnished by the Company to holders of the Units
and would make certain provisions of the Exchange Act, such as the short-swing
profit recovery provisions of Section 16(b), the requirement of furnishing a
proxy statement in connection with stockholders' meetings pursuant to Section
14(a) and the requirements of Rule 13e-3 under the Exchange Act with respect to
"going private" transactions, no longer applicable to the Units. Furthermore,
"affiliates" of the Company and persons holder "restricted securities" of the
Company may be deprived of the ability to dispose of the securities pursuant to
Rule 144 under the Securities Act. If registration of the Units under the
Exchange Act were terminated, the Units would no longer be "margin securities"
or eligible for NNM quotation. The Purchaser presently intends to seek to cause
the Company to terminate the registration of the Units under the Exchange Act as
soon after the consummation of the Offer or Second Step Transaction as the
requirements for termination of registration are met. In addition, following the
Second Step Transaction, the outstanding Callable Warrants may not meet the
requirements for registration under the Exchange Act, and the provisions of the
Exchange Act described
 
                                       41
<PAGE>   42
 
above applicable to transactions in the Units would similarly not apply to
transactions in the Callable Warrants.
 
     Margin Regulations.  The Units are currently "margin securities" under the
rule of the Board of Governors of the Federal Reserve System (the "Federal
Reserve Board"), which has the effect, among other things, of allowing brokers
to extend credit on the collateral of such Units for the purpose of buying,
carrying or trading in securities ("purpose loans"). Depending upon factors such
as the number of record holders of the Units and the number and market value of
publicly held Units, following the purchase of Units pursuant to the Offer or
following consummation of the Offer, the Units might no longer constitute
"margin securities" for purposes of the Federal Reserve Board's margin
regulations and therefore could no longer be used as collateral for purpose
loans made by brokers.
 
9.  FEES AND EXPENSES
 
     The following is an estimate of expenses to be incurred in connection with
the Offer and the Second Step Transaction, other than (i) the fees and expenses

                                THE TENDER OFFER
 
1.  TERMS OF THE OFFER; EXPIRATION DATE
 
     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), the Purchaser will accept for payment and pay for all Units
validly tendered prior to the Expiration Date (as defined below) and not
properly withdrawn as provided in "THE TENDER OFFER -- Section 4. Withdrawal
Rights." The term "Expiration Date" means 5:00 p.m., New York City time, on
October 28, 1996, unless and until the Purchaser, in its sole discretion (but
subject to the terms and conditions of the Purchase Agreement), shall have
extended the period during which the Offer is open, in which event the term
"Expiration Date" shall mean the latest time and date at which the Offer, as so
extended by the Purchaser, shall expire.
 
     Subject to the applicable rules and regulations of the Commission, the
Purchaser expressly reserves the right, in its sole discretion (but subject to
the terms and conditions of the Purchase Agreement), at any time and from time
to time, to extend the period during which the Offer is open for any reason,
including the failure to satisfy any of the conditions specified in "THE TENDER
OFFER -- Section 9. Certain Conditions of the Offer," and thereby delay
acceptance for payment of, or payment for, any Units, by giving oral or written
notice of such extension to the Depositary. There can be no assurance that the
Purchaser will exercise its right to extend the Offer. During any such
extension, all Units previously tendered and not properly withdrawn will remain
subject to the Offer, subject to the rights of a tendering Holder to withdraw
such Holder's Units. See "THE TENDER OFFER -- Section 4. Withdrawal Rights."
 
     Subject to the applicable rules and regulations of the Commission, the
Purchaser also expressly reserves the right, in its sole discretion (but subject
to the terms and conditions of the Purchase Agreement), at any time and from
time to time, to (i) delay acceptance for payment of or, regardless of whether
the Units were theretofore accepted for payment, payment for, any Units pending
receipt of any regulatory approvals that may be required as described in "THE
TENDER OFFER -- Section 10. Certain Legal Matters; Regulatory Approvals," (ii)
terminate the Offer and not accept for payment (or pay for) any Units if any of
the conditions referred to in "THE TENDER OFFER -- Section 9. Certain Conditions
of the Offer" have not been satisfied or upon the occurrence and during the
continuance of any of the events specified in "THE TENDER OFFER -- Section 9.
Certain Conditions of the Offer" and (iii) waive any condition or amend the
Offer in any respect, in each case, by giving oral or written notice of such
delay, termination, waiver or amendment to the Depositary and by making a public
announcement thereof. The Purchase Agreement provides that, without the consent
of the Company, as approved by the Special Committee, the Purchaser shall not
amend or waive the Minimum Condition or the Majority Consent Condition (as
defined below), extend the offer, reduce the maximum number of Units to be
purchased, reduce the price to be paid per Unit pursuant to the Offer and amend
any other material term of the Offer in a manner adverse to the Holders.
Pursuant to the Purchase Agreement, if on October 28, 1996, the Minimum
Condition has not been satisfied, the Purchaser may, not later than 9:00 a.m.,
eastern time, on the next business day following the Initial Expiration Date,
elect either (x) to extend the Offer for a period not to exceed 60 days and
amend the Offer to delete the Minimum Condition and add the Majority Consent
Condition, in which case, promptly thereafter, the Company shall commence to
convene a meeting or solicit the written consent of its shareholders for
approval of the Merger Plan, or (y) terminate the Offer and promptly return all
tendered Units, in which case, promptly thereafter, the Company shall commence
to convene a meeting or solicit the written consent of the its shareholders for
approval of the Merger Plan, in either case with such solicitation or meeting to
be conducted in accordance with applicable law and the terms of the Purchase
Agreement. The Majority Consent Condition is defined in the Purchase Agreement
to mean that the sum of (a) the Shares included in the Units tendered and not
withdrawn as of the new expiration date of the Offer (provided such Shares may
be voted in favor of the Merger Plan at the meeting or pursuant to the consent
solicitation by the Purchaser immediately after the purchase of the Units which
include such Shares in the Offer by the Purchaser) plus (b) the number of Shares
held by holders who have voted in favor of the Merger Plan at the meeting or
pursuant to the consent solicitation as of the new expiration date of the Offer
(but excluding any such Shares that would result
 
                                       43
<PAGE>   44
 
in double counting with (a) above) represents not less than a majority of the
Shares outstanding. The Purchaser acknowledges (x) that Rule 14e-1(c) under the
Exchange Act requires the Purchaser to pay the consideration offered or return
the Units tendered promptly after the termination or withdrawal of the Offer and
(y) that the Purchaser may not delay acceptance for payment of, or payment for
(except as provided in clause (i) of the first sentence of this paragraph), any
Units upon the occurrence of any of the conditions specified in "THE TENDER
OFFER -- Section 9. Certain Conditions of the Offer" without extending the
period of time during which the Offer is open.
 
     If the Minimum Condition or any other condition specified in "THE TENDER
OFFER -- Section 9. Certain Conditions of the Offer" is not fulfilled by the
Expiration Date, the Purchaser reserves the right (but shall not be obligated)
to (i) decline to purchase any of the Units tendered, return all tendered Units
to tendering Holders and terminate the Offer, (ii) subject to the terms and
conditions of the Purchase Agreement, extend the Offer and retain all tendered
Units until the expiration of the Offer, as extended, subject to the terms and
conditions of the Offer (including any rights of Holders to withdraw their
Units) or (iii) subject to the terms and conditions of the Purchase Agreement,
waive or reduce the condition and, subject to complying with applicable rules
and regulations of the Commission, accept for payment and purchase all Units
validly tendered.
 
     Any extension, delay, termination, waiver or amendment will be followed as
promptly as practicable by a public announcement thereof, such announcement, in
the case of an extension, to be made no later than 9:00 a.m., New York City
time, on the next business day after the previously scheduled Expiration Date.
Without limiting the manner in which the Purchaser may choose to make any public
announcement, except as provided by applicable law (including Rules 14d-4(c),
14d-6(d) and 14e-1 under the Exchange Act, which require that material changes
be promptly disseminated to Holders), the Purchaser will have no obligation to
publish, advertise or otherwise communicate any such public announcement other
than by issuing a release to the Dow Jones News Service.
 
     If, in accordance with the terms and conditions of the Purchase Agreement,
the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer, or waives a material condition of the Offer,
the Purchaser will disseminate additional tender offer materials (including by
public announcement as set forth above) and extend the Offer to the extent
required by Rules 14d-4(c), 14d-6(d) and 14e-1 under the Exchange Act. The
minimum period during which an offer must remain open following material changes
in the terms of the offer or information concerning the offer, other than a
change in price, a change in percentage of securities sought or a change in any
dealer's soliciting fee, will depend upon the facts and circumstances, including
the relative materiality of the changes. With respect to a change in price or,
subject to certain limitations, a change in the percentage of securities sought
or a change in any dealer's soliciting fee, a minimum ten business day period
from the day of such change is generally required to allow for adequate
dissemination to Holders. Accordingly, if, prior to the Expiration Date, the
Purchaser decreases the number of Units being sought, increases the
consideration offered pursuant to the Offer or adds a dealer's soliciting fee,
and if the Offer is scheduled to expire at any time earlier than the period
ending on the tenth business day from the date that notice of such increase,
decrease or addition is first published, sent or given to the Holders, the Offer
will be extended at least until the expiration of such ten business day period.
For purposes of the Offer, a "business day" means any day other than a Saturday,
Sunday or a federal holiday and consists of the time period from 12:01 a.m.
through 12:00 midnight, New York City time.
 
     The Company has elected to disseminate the Offer to the Holders. This Offer
to Purchase and the related Letter of Transmittal and, if required, other
relevant material will be mailed to record holders of Units and will be
furnished to brokers, dealers, commercial banks, trust companies and similar
persons whose names, or the names of whose nominees, appear on the Company's
list of Holders for subsequent transmittal to beneficial owners of Units.
 
2.  ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
 
     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), the Purchaser will purchase by accepting for payment, and paying
for, all Units validly tendered prior to the Expiration Date and not properly
withdrawn
 
                                       44
<PAGE>   45
 
(including Units validly tendered and not withdrawn during any extension of the
Offer, if the Offer is extended, subject to the terms and conditions of such
extension), promptly after the Expiration Date. In addition, subject to
complying with Rule 14e-1 under the Exchange Act, the Purchaser expressly
reserves the right, in its sole discretion (but subject to the terms and
conditions of the Purchase Agreement), to delay the acceptance for payment of,
or payment for, Units in order to comply, in whole or in part, with any other
applicable law.
 
     In all cases, payment for Units tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i)
certificates representing the Callable Common Stock and the Callable Warrants
included in the Units ("Unit Certificates"), (ii) the Letter of Transmittal (or
a facsimile thereof), properly completed and duly executed, with any required
signature guarantee, and (iii) any other documents required by the Letter of
Transmittal. Accordingly, payment may be made to tendering Holders at different
times if delivery of the Units and other required documents occurs at different
times.
 
     For purposes of the Offer, the Purchaser will be deemed to have accepted
for payment, and thereby purchased, Units validly tendered and not properly
withdrawn if, as and when the Purchaser gives oral or written notice to the
Depositary of the Purchaser's acceptance for payment of such Units pursuant to
the Offer. Upon the terms and subject to the conditions of the Offer, payment
for Units so accepted for payment pursuant to the Offer will be made by deposit
of the aggregate purchase price therefor with the Depositary, which will act as
agent for tendering Holders for the purpose of receiving payment from the
Purchaser and transmitting such payment to Holders whose Units have been
accepted for payment. UNDER NO CIRCUMSTANCES WILL INTEREST ON THE PURCHASE PRICE
FOR UNITS BE PAID BY THE PURCHASER, REGARDLESS OF ANY EXTENSION OF THE OFFER OR
ANY DELAY IN MAKING SUCH PAYMENT. Upon the deposit of funds with the Depositary
for the purpose of making payment to validly tendering Holders, the Purchaser's
obligation to make such payment shall be satisfied and such tendering Holders
must thereafter look solely to the Depositary for payment of the amounts owed to
them by reason of the acceptance for payment of Units pursuant to the Offer.
 
     If any tendered Units are not accepted for payment pursuant to the terms
and conditions of the Offer for any reason, or if the Unit Certificates are
submitted for more Units than are tendered, Unit Certificates representing Units
not purchased or not tendered will be returned, without expense to the tendering
Holder, as soon as practicable following expiration of termination of the Offer.
 
     If, prior to the Expiration Date, the Purchaser increases the consideration
to be paid per Unit, the Purchaser will pay such increased consideration for all
Units purchased pursuant to the Offer, whether or not such Units have been
tendered or purchased prior to such increase in consideration.
 
     The Purchase Agreement provides that it shall not be assigned except that
the Purchaser may assign its rights and obligations to Genzyme or to one or more
direct or indirect wholly owned subsidiaries of Genzyme which in a written
instrument shall make all the representations and warranties of the Purchaser
set forth therein and shall agree to assume all of the Purchaser's obligations
thereunder and be bound by all of the terms and conditions of the Purchase
Agreement; provided, however, that no such assignment shall relieve Genzyme or
the Purchaser of its obligations thereunder.
 
3.  PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING UNITS
 
     General.  Except as set forth below, in order for Units to be validly
tendered pursuant to the Offer, the Letter of Transmittal (or facsimile
thereof), properly completed and duly executed, together with any required
signature guarantees and any other documents required by the Letter of
Transmittal, must be received by the Depositary at one of its addresses set
forth on the back cover of the Offer to Purchase prior to the Expiration Date,
and either (i) Unit Certificates representing tendered Units must be received by
the Depositary at such address prior to the Expiration Date, or (ii) the
guaranteed delivery procedures set forth below must be complied with. Book-entry
transfer procedures are not available to Holders.
 
     No alternative, conditional or contingent tenders will be accepted and no
fractional Units will be purchased. All tendering Holders, by execution of the
Letter of Transmittal (or facsimile thereof), waive any right to receive any
notice of the acceptance of their Units for payment.
 
                                       45
<PAGE>   46
 
     THE METHOD OF DELIVERY OF UNIT CERTIFICATES, THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS IS AT THE SOLE OPTION AND RISK OF EACH TENDERING
HOLDER AND, EXCEPT AS OTHERWISE PROVIDED IN THIS SECTION 3, THE DELIVERY WILL BE
DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF DELIVERY IS BY
MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY
DELIVERY.
 
     Signature Guarantees.  Signatures on all Letters of Transmittal must be
guaranteed by a firm that is a bank, broker, dealer, credit union, savings
association or other entity which is a member in good standing of the Securities
Transfer Agents Medallion Program, the Stock Exchanges' Medallion Program or the
New York Stock Exchange, Inc. Medallion Signature Program (an "Eligible
Institution"), unless the Units tendered thereby are tendered (i) by a
registered Holder of Units who has not completed either the box entitled
"Special Delivery Instructions" or the box entitled "Special Payment
Instructions" on the Letter of Transmittal or (ii) for the account of an
Eligible Institution. See Instruction 1 of the Letter of Transmittal.
 
     If the Unit Certificates are registered in the name of a person other than
the signer of the Letter of Transmittal, or if payment is to be made, or Unit
Certificates for unpurchased Units are to be returned, to a person other than
the registered holder(s), then the tendered Unit Certificates must be endorsed
or accompanied by appropriate stock powers signed exactly as the name(s) of the
registered holder(s) appear on the Unit Certificates with the signature(s) on
such Unit Certificates or stock powers guaranteed by an Eligible Institution as
provided above and in the letter of transmittal. See Instructions 1 and 5 of the
Letter of Transmittal.
 
     Guaranteed Delivery.  If a Holder desires to tender Units pursuant to the
Offer and such Holder's Unit Certificates are not immediately available or time
will not permit all of the required documents to reach the Depositary prior to
the Expiration Date, such Units may nevertheless be tendered, provided that all
of the following conditions are satisfied:
 
          (a) such tender is made by or through an Eligible Institution;
 
          (b) a properly completed and duly executed Notice of Guaranteed
     Delivery, substantially in the form provided by the Purchaser herewith, is
     received by the Depositary, as provided below, prior to the Expiration
     Date; and
 
          (c) the Unit Certificates for all tendered Units, in proper form for
     transfer, in each case together with the Letter of Transmittal (or a
     facsimile thereof) properly completed and duly executed, with any required
     signature guarantees and any other documents required by the Letter of
     Transmittal are received by the Depositary within three NNM trading days
     after the date of execution of such Notice of Guaranteed Delivery.
 
     The Notice of Guaranteed Delivery may be delivered by hand or transmitted
by telegram, facsimile transmission or mail to the Depositary and must include a
guarantee by an Eligible Institution in the form set forth in the Notice of
Guaranteed Delivery.
 
     Notwithstanding any other provision hereof, payment for Units accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of Unit Certificates therefor, a properly completed
and duly executed Letter of Transmittal (or facsimile thereof), together with
any required signature guarantees and any other documents required by the Letter
of Transmittal. Accordingly, payment might not be made to all tendering Holders
at the same time, and will depend upon when Unit Certificates are received into
the Depositary's account.
 
     Backup Federal Income Tax Withholding.  Under the federal income tax laws,
the Depositary may, under certain circumstances, be required to withhold 31% of
the amount of any payments made to certain Holders pursuant to the Offer. TO
PREVENT SUCH BACKUP FEDERAL INCOME TAX WITHHOLDING WITH RESPECT TO PAYMENTS MADE
TO CERTAIN HOLDERS OF THE PURCHASE PRICE OF UNITS PURCHASED PURSUANT TO THE
OFFER, EACH SUCH HOLDER MUST PROVIDE THE DEPOSITARY WITH SUCH HOLDER'S CORRECT
TAXPAYER IDENTIFICATION NUMBER AND CERTIFY
 
                                       46
<PAGE>   47
 
THAT SUCH HOLDER IS NOT SUBJECT TO BACKUP FEDERAL INCOME TAX WITHHOLDING BY
COMPLETING THE SUBSTITUTE FORM W-9 INCLUDED IN THE LETTER OF TRANSMITTAL. SEE
INSTRUCTION 9 OF THE LETTER OF TRANSMITTAL.
 
     Appointment as Proxy.  By executing the Letter of Transmittal, a tendering
Holder irrevocably appoints designees of the Purchaser as the Holder's
attorneys-in-fact and proxies in the manner set forth in the Letter of
Transmittal, each with full power of substitution with respect to any Units
tendered thereby (and with respect to any and all other Units or other
securities issued or issuable in respect of such Units on or after September 20,
1996). All such powers of attorney and proxies will be considered irrevocable
and coupled with an interest in the tendered Units. This appointment will be
effective when, and only to the extent that, the Purchaser accepts such Units
for payment and deposits the purchase price therefor with the Depositary. Upon
such payment, all prior powers of attorney and proxies given by such Holder with
respect to such Units (and other Units and securities issued or issuable in
respect of such Units on or after September 20, 1996) will, without further
action, be revoked, and no subsequent powers of attorney and proxies may be
given nor any subsequent written consents executed by such Holder (and, if given
or executed, will not be deemed effective). Upon such payment by the Purchaser,
the designees of the Purchaser will, with respect to such Units and other
securities, be empowered to exercise all voting and other rights of such Holder
as they in their sole discretion may deem proper at any annual or special
meeting of the Holders, or any adjournment or postponement thereof, by written
consent in lieu of any such meeting or otherwise. The Purchaser reserves the
right to require that, in order for Units to be deemed validly tendered,
immediately upon the Purchaser's payment for such Units, the Purchaser must be
able to exercise full voting and other rights of a record and beneficial holder,
including voting at any meeting of Holders.
 
     Determination of Validity.  All questions as to the validity, form,
eligibility (including the time of receipt) and acceptance for payment of any
tendered Units pursuant to any of the procedures described above will be
determined by the Purchaser, in its sole discretion, which determination will be
final and binding on all parties. The Purchaser reserves the absolute right to
reject any and all tenders of any particular Units determined by it not to be in
appropriate form or the acceptance of or payment for which may, in the opinion
of its counsel, be unlawful. The Purchaser also reserves the absolute right to
waive any of the conditions of the Offer (subject to the terms and conditions of
the Purchase Agreement) or any defect or irregularities in the tender of any
particular Units, whether or not similar defects or irregularities are waived in
the case of any other Units. The Purchaser's interpretations of the terms and
conditions of the Offer (including the Letter of Transmittal and Instructions
thereto) will be final and binding. No tender of Units will be deemed to have
been validly made until all defects and irregularities have been cured or
waived. None of Genzyme, the Purchaser, any of their respective affiliates or
assigns, the Dealer Manager, the Information Agent, the Depositary nor any other
person will be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give any such
notification.
 
     The Purchaser's acceptance for payment of Units tendered pursuant to the
Offer will constitute a binding agreement between the tendering Holder and the
Purchaser upon the terms and subject to the conditions of the Offer.
 
4.  WITHDRAWAL RIGHTS
 
     Except as otherwise provided in this Section 4, tenders of Units made
pursuant to the Offer are irrevocable. Units tendered pursuant to the Offer may
be withdrawn at any time prior to the Expiration Date and, unless theretofor
accepted for payment as provided herein, may also be withdrawn at any time after
November 25, 1996.
 
     If the Purchaser extends the Offer, is delayed in, or delays, its
acceptance for payment or payment for Units or is unable to accept for payment
or pay for Units for any reason, then, without prejudice to the Purchaser's
other rights under the Offer, tendered Units may nevertheless be retained by the
Depositary, on behalf of the Purchaser, and may not be withdrawn except to the
extent tendering Holders are entitled to and duly exercise withdrawal rights as
described in this Section 4. Any such delay will be accompanied by an extension
of the Offer to the extent required by law.
 
                                       47
<PAGE>   48
 
     In order for a withdrawal to be effective, a written, telegraphic or
facsimile transmission notice of withdrawal must be timely received by the
Depositary at one of its addresses set forth on the back cover of this Offer to
Purchase. Any such notice of withdrawal must specify the name of the person who
tendered the Units to be withdrawn, the number of Units to be withdrawn and the
name of the registered holder of such Units, if different from that of the
person who tendered such Units. If Unit Certificates to be withdrawn have been
delivered or otherwise identified to the Depositary, then, prior to the physical
release of such Unit Certificates, the tendering Holder must also submit the
serial numbers shown on such Unit Certificates to the Depository and the
signatures on the notice of withdrawal must be guaranteed by an Eligible
Institution, unless such Units have been tendered for the account of an Eligible
Institution.
 
     Withdrawals may not be revoked and any Units properly withdrawn will
thereafter be deemed not to have been validly tendered for purposes of the
Offer. However, withdrawn Units may be re-tendered at any time prior to the
Expiration Date by following one of the procedures described in "THE TENDER
OFFER -- Section 3. Procedures for Accepting the Offer and Tendering Units."
 
     All questions as to the form and validity (including the time of receipt)
of any notice of withdrawal will be determined by the Purchaser, in its sole
discretion, whose determination will be final and binding. None of Genzyme, the
Purchaser, any of their affiliates or assigns, the Dealer Manager, the
Information Agent, the Depositary or any other person will be under any duty to
give notification of any defects or irregularities in any notice of withdrawal
or incur any liability for failing to give any such notification.

- ---------------
 
(1)  In May 1992, Neozyme II paid a technology license fee of $5,000,000 to
     Genzyme in consideration for Genzyme entering into the Technology License
     Agreement and in recognition of Genzyme's expertise and expenditures in
     developing technology licensed to Neozyme II.
 
(2)  Cash and investments includes cash, cash equivalents, and short-term
     investments.
 
(3)  In May 1992, Neozyme II issues a note in the principal amount of $100,000
     to Genzyme (the "Series 1992 Note") which is due on the day following the
     termination of the Purchase Option Agreement with Genzyme and may not be
     prepaid.
 
(4) The ratio of earnings to fixed charges is not presented for Neozyme II due
    to the absence of fixed charges.
 
     During the course of discussions between representatives of Genzyme and the
Special Committee that led to the execution of the Purchase Agreement, certain
non-public business and financial information about the Company was reviewed.
The Company does not as a matter of course make public any forecasts or
projections as to future performance or earnings, and the information set forth
below is included in this Offer to Purchase only because such information was
received by representatives of the parties. The forecasted and projected
financial information set forth below was not prepared with a view to public
disclosure or compliance with published guidelines of the Commission or the
guidelines established by the American Institute of Certified Public Accountants
regarding projections and forecasts. None of Genzyme, the Purchaser or the
Company, nor any of their respective financial advisors, assumes any
responsibility for the accuracy of this information. While presented with
numerical specificity, this information is based upon a variety of assumptions
relating to the business of the Company which may not be realized and is subject
to significant
 
                                       50
<PAGE>   51
 
uncertainties and contingencies, all of which are difficult to predict and many
of which are beyond the control of the Company. There can be no assurance that
the projected or forecasted results will be realized, and actual results may
vary materially and adversely from those shown. The projections were based on
certain assumptions regarding patient growth, market penetration, royalty income
and other factors. The projections forecast base case net losses of
approximately $8 million to $11 million in each of 1996 through 2002, base case
revenue for 2003, 2004 and 2005 of approximately $26 million, $165 million and
$293 million, respectively, and base case net income for 2003, 2004 and 2005 of
approximately $300,000, $42 million and $76 million, respectively.
 
7.  CERTAIN INFORMATION CONCERNING GENZYME AND THE PURCHASER
 
     Genzyme.  Genzyme, a Massachusetts corporation with its principal executive
offices located at One Kendall Square, Cambridge, MA 02139, is a diversified,
integrated human health care company which operates in five major business
areas. Genzyme's business activities in the areas of pharmaceuticals, genetic
diagnostic services and therapeutic diagnostic and surgical products and
pharmaceuticals are organized as the Genzyme General Division. Genzyme's
activities to develop, manufacture and market technologically advanced products
for the treatment or cartilage damage, severe burns and chronic skin ulcers are
conducted through the Genzyme Tissue Repair Division. Genzyme's common stock is
divided into two classes, General Division Common Stock and Tissue Repair
Division Common Stock, each of which is traded in the over-the-counter market
and is included on the NNM under the symbol "GENZ" and "GENZL," respectively.
 
     Genzyme is subject to the disclosure requirements of the Exchange Act and
in accordance therewith is required to file reports, proxy statements and other
information with the Commission relating to its business, financial condition
and other matters. Such reports, proxy statements and other information are
available for inspection and copying at prescribed rates at the offices of the
Commission as set forth in "THE TENDER OFFER -- Section 6. Certain Information
Concerning the Company."
 
     In addition to the Offer described herein, Genzyme has engaged in the
following transactions or negotiations with its affiliates in the last fiscal
year:
 
          (i) IG Laboratories, Inc. In October 1994, Genzyme management began
     consulting with its investment bankers regarding the potential acquisition
     of all of the shares of the common stock of IG Laboratories, Inc., a
     majority owned subsidiary of Genzyme ("IG"), not then owned by Genzyme. At
     the same time, the IG Board established a committee (the "IG Independent
     Committee") consisting of the directors of IG who were not affiliated with
     Genzyme. The IG Independent Committee was charged with investigating and
     considering the options available to IG for the further development of its
     business or for a business combination with a third party, including
     Genzyme. Between October 1994 and February 1995, the IG Independent
     Committee consulted independent financial and legal advisors. Such advisors
     began meeting with representatives of Genzyme in January 1995.
 
          On February 15, 1995, Genzyme sent a proposal to the IG Independent
     Committee to acquire all outstanding shares of IG's common stock not owned
     by Genzyme through a merger of IG and Genzyme in which IG stockholders
     other than Genzyme would receive shares of Genzyme General Division Common
     Stock in exchange for their shares of IG Common Stock. On May 18, 1995,
     Genzyme and the IG Independent Committee executed a letter of intent
     pursuant to which the IG Independent Committee recommended to the full IG
     Board of Directors the acquisition by Genzyme of all the outstanding shares
     of IG's Common Stock. Genzyme and IG entered into an Agreement and Plan of
     Merger dated as of June 10, 1995 providing, among other things, for the
     merger of IG with and into Genzyme and for the exchange of all outstanding
     shares of IG Common Stock (other than shares held by IG as treasury stock
     or by Genzyme or subsidiaries of IG or Genzyme) for a number of shares of
     Genzyme General Division Common Stock determined by dividing $7.00 by the

 (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 July 1993, GTR received a technology license fee of $2,000,000 from
     Neozyme I related to expansion of the field of the Vianain(R) debriding
     product.
 
 (3) Includes charges related to the purchase of in-process research and
     development totaling $51.1 million, $49.0 million, $11.2 million and $14.2
     million, respectively, for the years ended December 31, 1992, 1993, 1994
     and 1995; impaired goodwill and restructuring costs totaling $26.5 million
     for the year ended December 31, 1993, and charges for purchase options and
     financing expenses totaling $16.9 million, for the year ended December 31,
     1992.
 
 (4) Reflects July 25, 1996 2-for-1 stock split of shares of General Division
     Stock.
 
 (5) The ratio of earnings to fixed charges is calculated by dividing the sum of
     (i) net income (loss) before income taxes and extraordinary credits and
     (ii) fixed charges excluding capitalized interest, by fixed charges. Fixed
     charges consist of interest (expensed and capitalized), amortization of
     debt issuance costs and the estimated interest portion of rent expense.
     Fixed charges exceeded earnings for the years ended December 31, 1992 and
     1993 by $12.2 million and $17.3 million, respectively.
 
 (6) EBITDA represents earnings before interest expense, income taxes,
     depreciation and amortization and extraordinary items. Interest costs
     include interest expensed and interest capitalized. EBITDA should not be
     considered an alternative measure of the Company's net income, operating
     performance, cash flow or liquidity. The ratio of EBITDA to interest costs
     is included herein to provide additional information related to the
     Company's ability to service debt.
 
 (7) Cash and investments includes cash, cash equivalents, and short- and
     long-term investments.
 
 (8) Genzyme has an available line of credit with a commercial bank of $215
     million which may be used by either the General or Tissue Repair Division.
     As of June 1996, Genzyme's Tissue Repair Division ("GTR") borrowed $15
     million under this credit line at an interest rate of approximately 6.06%
     as temporary financing for its manufacturing capacity expansion project. In
     July 1996, the General Division used $200 million to finance the
     acquisition of DSP.
 
 (9) In April 1996, the Company acquired Genetrix, Inc., in a tax free exchange
     of General Division Stock which was accounted for as a purchase. In the
     aggregate, approximately 1,380,000 shares of General Division Stock valued
     at $36.5 million were issued. In July, the Company acquired DSP for cash of
     approximately $250.8 million financed by cash of $50.8 million and line of
     credit borrowings of $200 million.
 
(10) 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 General Division Stock in
    March 1996.

(1) On May 1, 1996, the Company acquired Genetrix Inc., a privately held genetic
    testing laboratory based in Phoenix, Arizona, in a tax-free exchange of
    General Division Common Stock. In the aggregate, approximately 1,380,000
    shares of General Division Common Stock, valued at approximately $36.5
    million, were issued for all the outstanding shares of Genetrix preferred
    stock and Genetrix common stock, (together with the Genetrix Preferred Stock
    "Genetrix Stock"). The acquisition was accounted for as a purchase. The
    total purchase price of approximately $39.7 million included acquisition
    costs of $3.8 million. Approximately $35 million of the excess purchase
    price was allocated to goodwill and is being amortized over 15 years. On
    July 1, 1996, Genzyme completed the acquisition of Deknatel, Snowden,
    Pencer, Inc., a privately held specialty surgical products company. The
    Company paid approximately $250 million which was partially funded by $200
    million borrowed under a revolving credit facility. The total purchase price
    of $250.8 million included acquisition costs of $5.8 million. Approximately
    $36 million was allocated to tangible net assets, $70 million was allocated
    to patents and tradenames (useful life of 12 and 40 years, respectively),
    $24.2 million to in-process technology and $127.8 million to goodwill
    (useful life of 40 years). The amount allocated to in-process technology was
    charged to expense and is reflected as a charge to accumulated deficit in
    the pro forma balance sheet but is not reflected in the pro forma statement
    of operations as it is a material nonrecurring charge. On September 23,
    1996, Genzyme announced that it had signed a definitive Purchase Agreement
    with Neozyme II under which Genzyme will commence a tender offer for all
    outstanding units of Neozyme II at $45 per Unit in cash. The unaudited pro
    forma consolidated financial data presented herein assumes that all
    outstanding Units are tendered in the Offer. The total purchase price of
    $109.7 million includes acquisition costs of $1.0 million and has been
    allocated to the net assets of Neozyme II of $14.1 million and to in-process
    technology of $95.6 million. The amount allocated to in-process technology
    is reflected as a charge to accumulated deficit in the pro forma balance
    sheet and is not reflected in the pro forma statement of operations as it is
    a material nonrecurring charge which will be charged to expense upon
    completion of the acquisition.
(2) Includes charges related to the purchase of in-process research and
    development of $14.2 million for the year ended December 31, 1995.
(3) The ratio of earnings to fixed charges is calculated by dividing the sum of
    (i) net income (loss) before income taxes and extraordinary credits and (ii)
    fixed charges, by fixed charges. Fixed charges consist of interest (expensed
    and capitalized), amortization of debt issuance costs and the estimated
    interest portion of rent expense.
(4) Cash and investments includes cash, cash equivalents, and short- and
    long-term investments.
(5) 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 General Division Stock in
    March 1996.

     expense and is reflected as a charge to accumulated deficit in the pro
     forma balance sheet but is not reflected in the pro forma statement of
     operations as it is a material nonrecurring charge. On September 23, 1996,
     Genzyme announced that it had signed a definitive Purchase Agreement with
     Neozyme II under which Genzyme will commence a tender offer for all
     outstanding units of Neozyme II at $45 per Unit in cash. The unaudited
     summary pro forma financial combined financial data presented herein
     assumes that all outstanding Units are tendered in the Offer. The total
     purchase price of $109.7 million includes acquisition costs of $1.0 million
     and has been allocated to the net assets of Neozyme II of $14.1 million and
     to in-process technology of $95.6 million. The amount allocated to
     in-process technology is reflected as a charge to accumulated deficit in
     the pro forma balance sheet and is not reflected in the pro forma statement
     of operations as it is a material nonrecurring charge which will be charged
     to expense upon completion of the acquisition.
 
(2) Includes charges related to the purchase of in-process research and
     development $14.2 million for the year ended December 31, 1995.
(3) Cash and investments includes cash, cash equivalents, and short- and
     long-term investments.
(4) 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 General Division Stock in
     March 1996.
 
     8. SOURCE AND AMOUNT OF FUNDS.  The total amount of funds required by the
Purchaser to purchase 2,415,000 Units pursuant to the Offer, and to pay related
fees and expenses is estimated to be approximately $109 million. The Purchaser
expects to obtain such funds from Genzyme. Genzyme intends to obtain such funds
from its available corporate funds. Obtaining financing is not a condition to
the Offer or the Second Step Transaction.
 
     9. CERTAIN CONDITIONS OF THE OFFER.  Notwithstanding any other provisions
of the Offer, and in addition to the condition that Units that would constitute
not less than a majority of the Units outstanding are validly tendered prior to

to accept for payment and pay for any Units tendered pursuant to the Offer, may
postpone the purchase of, and payment for, Units tendered, and may terminate or

or not any Units have theretofore been accepted for payment and paid for
pursuant to the Offer) any of the following shall occur or shall be determined
by the Purchaser to have occurred and remain in effect:
 
          (a) except for matters which affect generally the economy or the
     industry in which the Company is engaged and except for continued losses
     incurred by the Company as a result of its operations and continued
     depletion of its cash resources in the ordinary course of business or
     consistent with the annual workplan currently in effect, any change shall
     have occurred in the business, properties, assets, liabilities,
     capitalization, stockholders' equity, financial condition, operations,
     licenses or franchises or results of operations of the Company which has a
     Material Adverse Effect (as defined in the Purchase Agreement); or
 
          (b) there shall have been instituted or be pending any action,
     proceeding, application or counterclaim before any court or governmental or
     regulatory body which (i) challenges the validity of or seeks to restrain
     the consummation of or to impose any material limitation, on any
     transaction contemplated by the Purchase Agreement or seeks (ii) to obtain
     any material amount of damages in connection with such transactions; or
 
                                       62
<PAGE>   63
 
          (c) any statute, regulation, order or injunction shall have been
     enacted, entered, enforced or deemed applicable to the Offer or the Second
     Step Transaction that is reasonably likely to, directly or indirectly,
     result in any of the consequences referred to in paragraph (b) above; or
 
          (d) the Board of Directors of the Company shall have publicly
     (including by amendment of its Schedule 14D-9) withdrawn or modified in a
     manner adverse to the Purchaser its approval or recommendation of the Offer
     or shall have resolved to do so; or
 
          (e) the representations and warranties of the Company set forth in the
     Purchase Agreement shall not be true in any material respect as though made
     on such date or the Company shall have failed in any material respect to
     perform any material obligation or covenant required in the Purchase
     Agreement to be performed or complied with by it; or
 
          (f) the Company shall have entered into, or shall have publicly
     announced its intention to enter into, an agreement or agreement in
     principle with respect to any Acquisition Proposal (as defined in the
     Purchase Agreement).
 
     10. CERTAIN LEGAL MATTERS; REGULATORY APPROVALS.  Neither Genzyme nor the
Purchaser is aware of any license or regulatory permit that appears to be
material to the business of the Company that might be adversely affected by the
Purchaser's acquisition of Units as contemplated herein. Neither Genzyme nor the
Purchaser is aware of any other material filing, approval or other action by any
federal or state governmental or administrative authority that would be required
for the acquisition of Units by the Purchaser as contemplated herein, including
any approval required under the Hart-Scott-Rodino Act. Should any such approval
or action be required, it is currently contemplated that such approval or action
would be sought. There is, however, no present intention to delay the purchase
of Units tendered pursuant to the Offer pending the outcome of any such approval
or action. There can be no assurance that any such approval or action, if
needed, would be obtained without substantial conditions or that adverse
consequences might not result to Genzyme's, the Purchaser's or the Company's
business in the event that such approvals were not obtained or such actions were
not taken. The Purchaser's obligation under the Offer to accept for payment and
pay for Units is subject to certain conditions, including conditions relating to
the legal matters discussed in this Section 10. See "THE TENDER OFFER -- Section
9. Certain Conditions of the Offer."

without limitation, the issuance of additional Shares pursuant to a stock
dividend or stock split or the issuance of rights for the purchase of any
securities) with respect to the Callable Common Stock that is payable or
distributable to Holders of record on a date occurring prior to the transfer to
the name of the Purchaser or its nominees or transferees on the Company's stock
transfer records of the Units purchased pursuant to the Offer, then, without
prejudice to the Purchaser's rights described in "THE TENDER OFFER -- Section 9.
Certain Conditions of the Offer," (i) the purchase price per Unit payable by the
Purchaser pursuant to the Offer will be reduced in the amount of any such cash
dividend or distribution and (ii) the whole of any non-cash dividend or
distribution (including, without limitation, additional shares or rights as
aforesaid) will be required to be remitted promptly and transferred by each
tendering Holder to the Depositary for the account of the Purchaser accompanied
by appropriate documentation of transfer and pending such remittance or
appropriate assurance thereof, the Purchaser will be entitled to all rights and
privileges as owner of any such non-cash dividend, distribution or right, and
may withhold the entire purchase price or deduct from the purchase price the
amount of value of such non-cash dividend, distribution or right, as determined
by the Purchaser in its sole discretion.
 
     If, on or after September 20, 1996, the Company should split the shares of
Callable Common Stock or combine or otherwise change the shares of Callable
Common Stock or its capitalization, then, without prejudice to the Purchaser's
rights described in "THE TENDER OFFER -- Section 9. Certain Conditions of the
Offer," appropriate adjustments to reflect such split, combination or change may
be made by the Purchaser in the purchase price and other terms of the Offer,
including, without limitation, the number or type of securities offered to be

Gentlemen:

You have requested our opinion as to the fairness from a financial point of view
to the holders of the outstanding shares of callable common stock, par value
$1.00 per share ("Common Stock"), of Neozyme II Corporation ("Neozyme" or the
"Company") of the consideration to be received by such holders in connection
with a proposed transaction (the "Proposed Transaction") pursuant to which an
affiliate of Genzyme Corporation ("Genzyme") will offer to purchase the
outstanding units of Neozyme (the "Units") at a purchase price of $45.00 per
Unit in cash (the "Offer"). As of the date hereof, all of the outstanding Common
Stock is owned as part of a Unit, each of which consists of (i) one share of
Common Stock and (ii) one callable warrant to purchase two shares of Genzyme
General Division Common Stock and 0.135 shares of Genzyme Tissue Repair Division
Common Stock. The Offer will be made by means of offering documents (the "Offer
Documents") to be filed with the Securities and Exchange Commission. If the
Offer is consummated, but not all of the Units are tendered and accepted or, if
the Offer is terminated in accordance with Section 1.1(b)(ii) of the Purchase
Agreement, Genzyme has, pursuant to a Purchase Agreement (the "Purchase
Agreement") dated as of September 20, 1996, agreed to effect a second step
transaction (the "Second Step Transaction") in which Genzyme will acquire,
directly or indirectly, all of the remaining Common Stock in exchange for cash
in an amount equal to $29.00 per share of Common Stock.

Hambrecht & Quist LLC ("Hambrecht & Quist"), as part of its investment banking
services, is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, strategic transactions,
corporate restructurings, negotiated underwritings, secondary distributions of
listed and unlisted securities, private placements and valuations for corporate

Committee of the  Board of Directors of Neozyme in connection with the Proposed
Transaction, and we will receive a fee for our services, which include the
rendering of this opinion.

We are familiar with Genzyme and have, from time to time, provided financial
advisory services to Genzyme, and we have received fees for rendering these
services. In July 1996, we acted as managing underwriter for a public offering
of Genzyme Transgenics Corporation, an affiliate of Genzyme. In the ordinary
course of business, Hambrecht & Quist acts as a market maker and broker in the
publicly traded securities of Neozyme and Genzyme and receives customary
compensation in connection therewith, and also provides research coverage for
Genzyme. In the ordinary course of business, Hambrecht & Quist actively trades
in the equity securities of Neozyme and Genzyme for its own account and for
the accounts of its customers and, accordingly, may at any time hold a long or
short position in such securities. Hambrecht & Quist may in the future provide
additional investment banking or other financial advisory services to Genzyme.

In connection with our review of the proposed Transaction, and in arriving at
our opinion, we have, among other things:

        (i)  reviewed the publicly available consolidated financial statements
             of Neozyme for recent years and interim periods to date and certain
             other relevant financial and operating data of Neozyme made
             available to us from published sources and from the internal
             records of Neozyme;

      (ii)   discussed with certain members of the managements of Neozyme and
             Genzyme the business, financial condition and prospects of 
             Neozyme;

     (iii)   reviewed the publicly available consolidated financial statements
             of Genzyme for recent years and interim periods to date;

      (iv)   reviewed certain internal financial and operating information,
             including certain projections, relating to Neozyme prepared by the
             management of Genzyme;

       (v)   reviewed the recent reported prices and trading activity for the
             Common Stock and compared such information and certain financial
             information of Neozyme with similar information for certain other
             companies engaged in businesses we considered comparable to that of
             Neozyme;

      (vi)   reviewed the financial terms, to the extent publicly available, of
             certain comparable acquisition transactions;

     (vii)   reviewed drafts of the Purchase Agreement, the Offer Documents and
             certain other materials to be filed with the Securities and
             Exchange Commission in connection with the Offer; and

      (ix)   performed such other analyses and examinations and considered such
             other information, financial studies, analyses and investigations
             and financial, economic and market data as we deemed relevant.

In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of all of the information concerning Neozyme and Genzyme
considered in connection with our review of the Proposed Transaction, and we
have not assumed any responsibility for independent verification
<PAGE>   73

of such information. We have not prepared any independent valuation or
appraisal of any of the assets or liabilities of Neozyme, nor have we conducted
a physical inspection of the properties and facilities of the Company. With
respect to the financial forecasts and projections made available to us and
used in our analysis, we have assumed that they reflect the best currently
available estimates and judgments of the expected future financial performance
of Neozyme. For purposes of this opinion, we have assumed that Neozyme is not a
party to any pending transactions, including external financings,
recapitalizations or material merger discussions, other than the Proposed
Transaction and those activities undertaken in the ordinary course of
conducting its business. Our opinion is necessarily based upon market,
economic, financial and other conditions as they exist and can be evaluated as
of the date of this letter and any change in such conditions would require a
reevaluation of this opinion. We were not requested to, and did not, formally
solicit indications of interest from any other parties in connection with a
possible acquisition of, or business combination with, Neozyme.

It is understood that this letter is for the information of the Special
Committee and the Board of Directors only and may not be used for any other
purpose without our prior written consent; provided, however, that this letter
may be reproduced in full in any filing with the Securities and Exchange
Commission pursuant to the Securities Exchange Act of 1934, including Schedules
14D-1, 14-D9 and 13E-3 to be filed in connection with the Offer. This letter
does not constitute a recommendation to any Neozyme stockholder as to whether
such stockholder should accept the Offer. In addition, we express no opinion,
however, as to the adequacy of any consideration received in the Proposed
Transaction by Genzyme or any of its affiliates.

Based upon and subject to the foregoing and after considering such other
matters as we deem relevant, we are of the opinion that as of the date hereof
the consideration to be received by the holders of the Units pursuant to the
Offer and the consideration to be received by the holders of the Common Stock
pursuant to the Second Step Transaction is fair to such holders from a
financial point of view.

Very truly yours,

Hambrecht & Quist LLC

[ROBERTSON STEPHENS & COMPANY LETTERHEAD]


                                                            September 20, 1996

Board of Directors
Genzyme Corporation
One Kendall Square
Cambridge, MA 02139-1562

Members of the Board:

You have asked our opinion with respect to the fairness from a financial point
of view, as of the date hereof, to Genzyme Corporation ("Genzyme"), of the Offer
Price (as defined below) to be paid by Genzyme in the proposed acquisition
(the "Acquisition") of Neozyme II Corporation ("Neozyme") by Neozyme II
Acquisition Corporation (the "Purchaser"), a wholly owned subsidiary of
Genzyme, pursuant to the Purchase Agreement (the "Agreement") proposed to be
entered into among Genzyme, the Purchaser and Neozyme.

Under the terms of the Agreement, the Purchaser will make a tender offer (the
"Offer") to purchase all of the outstanding units (the "Units"), each of which
consists of (i) one share of Callable Common Stock, par value $1.00 per share
(the "Shares"), of Neozyme and (ii) Callable Warrants (the "Warrants") to
purchase two shares of General Division Common Stock of Genzyme and 0.135
shares of Tissue Repair Division Common Stock of Genzyme, at a price of $45.00
per Unit, net to the seller in cash (the "Offer Price"). In addition, if any
Units remain outstanding following the completion of the Offer, Genzyme will
effect a transaction (the "Second Step Transaction") pursuant to which the
Shares associated with such outstanding Units will be acquired, directly or
indirectly, by Genzyme and the Warrants associated with such outstanding Units
will remain outstanding. In the Second Step Transaction, holders of such
outstanding Units will receive $29.00 in cash per Share. The terms and
conditions of the Offer and the Second Step Transaction are set out more fully
in the Agreement.

For purposes of this opinion we have: (i) reviewed financial information
regarding Neozyme furnished to us by Neozyme, including certain financial
forecasts prepared by the management of Neozyme; (ii) reviewed publicly
available information regarding Neozyme; (iii) held discussions with the
management of Neozyme concerning the business, past and current business
operations, financial condition and future prospects of Neozyme; (iv) reviewed
a draft dated September 20, 1996 of the Agreement; (v) reviewed the stock price
and trading history of Neozyme; (vi) reviewed the valuations of publicly traded
companies that we deemed comparable to Neozyme; (vii) compared the financial
terms of the Acquisition with other transactions which we deemed

relevant; (viii) prepared a discounted cash flow analysis of Neozyme; (ix)
analyzed the value of the Warrants; and (x) made such other studies and
inquiries, and reviewed such other data, as we deemed relevant.

In connection with our opinion we have not independently verified any of the
foregoing information and have relied on all such information being complete
and accurate in all material respects. Furthermore, we have not made any
independent appraisal of the properties or assets and liabilities of Neozyme,
nor have we been furnished with any such evaluations or appraisals. With
respect to the financial forecasts (and the assumptions and bases therefor) of
Neozyme provided to us by the management of Neozyme, we have assumed that such
forecasts have been reasonably prepared in good faith on the basis of
reasonable assumptions and reflect the best available estimates and judgments
of the management of Neozyme as to the likely future financial performance of
Neozyme. In that regard we have relied on the assumptions of the management of
Neozyme with respect to the effect on such forecasts of the potential outcome
of Neozyme's pending patent applications. This opinion is necessarily based
upon market, economic and other conditions that exist and can be evaluated as
of the date of this letter, and on information available to us as of the date
hereof.

We have acted as financial advisor to Genzyme in connection with the
Acquisition and will act as Dealer Manager in connection with the Offer. A
portion of our fees in connection with such services will be payable upon
consummation of the Offer. In the ordinary course of our business, we may
actively trade the securities of Genzyme and Neozyme for our own account and
for the accounts of our customers and, accordingly, may at any time hold a long
or short position in such securities.

It is understood that this letter is for the information of the Board of
Directors of Genzyme.

Based upon and subject to the foregoing considerations, it is our opinion that,
as of the date hereof, the Offer Price to be paid by Genzyme in the Acquisition
is fair to Genzyme from a financial point of view.

                                Very truly yours,


                                ROBERTSON, STEPHENS & COMPANY LLC

                                   ANNEX III
     SECTION 83 OF THE BVI INTERNATIONAL BUSINESS COMPANIES ORDINANCE, 1984
 
                SUMMARY OF STOCKHOLDER APPRAISAL RIGHTS AND TEXT
   OF SECTION 83 OF THE BVI INTERNATIONAL BUSINESS COMPANIES ORDINANCE, 1984
 
     Summary of Stockholder Appraisal Rights.  No appraisal rights are available
in connection with the Offer. However, if the Second Step Transaction is a
merger, consolidation, sale or other disposition of more than 50 percent of the
assets of the Company, or a redemption, stockholders will have certain rights
under the BVI Law to dissent and demand appraisal of, and to receive payment in
cash of the fair value of, their shares of Callable Common Stock. Such rights to
dissent, if the statutory procedures were complied with, could lead to an
arbitration proceeding to determine the fair value of the Callable Common Stock,
as of the day prior to the date on which the stockholders' vote was taken
approving the Second Step Transaction (excluding any appreciation or
depreciation directly or indirectly induced by the action or its proposal),
required to be paid in cash to such dissenting holders for their shares of
Callable Common Stock. The value determined in an arbitration proceeding could
be the same, more or less than the portion of the purchase price per Unit
attributable to the share of Callable Common Stock included in each Unit in the
Offer or the consideration per share of Callable Common Stock to be paid in the
Second Step Transaction.
 
RIGHTS OF DISSENTERS
 
     83. (1) A member of a company incorporated under this Ordinance is entitled
to payment of the fair value of his shares upon dissenting from
 
          (a) a merger, if the company is a constituent company, unless the
     company is the surviving company and the member continues to hold the same
     or similar shares;
 
          (b) a consolidation, if the company is a constituent company;
 
          (c) any sale, transfer, lease, exchange or other disposition of more
     than 50 percent of the assets or business of the company, if not made in
     the usual or regular course of the business carried on by the company, but
     not including
 
             (i) a disposition pursuant to an order of the court having
        jurisdiction in the matter;
 
             (ii) a disposition for money on terms requiring all or
        substantially all net proceeds to be distributed to the members in
        accordance with their respective interests within one year after the
        date of disposition; or
 
             (iii) a transfer pursuant to the power described in subsection (2)
        of section 9;
 
          (d) a redemption of his shares by the company pursuant to section 81;
     and
 
          (e) an arrangement, if permitted by the court.
 
     (2) A member who desires to exercise his entitlement under subsection (1)
must give to the company, before the meeting of members at which the action is
submitted to a vote, or at the meeting but before the vote, written objection to
the action; but an objection is not required from a member to whom the company
did not give notice of the meeting in accordance with this Ordinance or where
the proposed action is authorized by written consent of members without a
meeting.
 
     (3) An objection under subsection (2) must include a statement that the
member proposes to demand payment for his shares if the action is taken.
 
     (4) Within 20 days immediately following the date on which the vote of
members authorizing the action is taken, or the date on which written consent of
members without a meeting is obtained, the company must give written notice of
the authorization or consent to each member who gave written objection or from
whom written objection was not required, except those members who voted for, or
consented to in writing, the proposed action.
 
<PAGE>   77
 
     (5) A member to whom the company was required to give notice who elects to
dissent must, within 20 days immediately following the date on which the notice
referred to in subsection (4) is given, give to the company a written notice of
his decision to elect to dissent, stating
 
          (a) his name and address;
 
          (b) the number and classes or series of shares in respect of which he
     dissents; and
 
          (c) a demand for payment of the fair value of his shares;
 
     and a member who elects to dissent from a merger under section 77 must give
     to the company a written notice of his decision to elect to dissent within
     20 days immediately following the date on which the copy of the plan or
     merger or an outline thereof is given to him in accordance with section 77.
 
     (6) A member who dissents must do so in respect of all shares that he holds
in the company.
 
     (7) Upon the giving of a notice of election to dissent, the member to whom
the notice relates ceases to have any of the rights of a member except the right
to be paid the fair value of his shares.
 
     (8) Within 7 days immediately following the date of the expiration of the
period within which members may give their notices of election to dissent, or
within 7 days immediately following the date on which the proposed action is put
into effect, whichever is later, the company or, in the case of a merger or
consolidation, the surviving company or the consolidated company, must make a
written offer to each dissenting member to purchase his shares at a specified
price that the company determines to be their fair value; and if, within 30 days
immediately following the date on which the offer is made, the company making
the offer and the dissenting member agree upon the price to be paid for his
shares, the company shall pay to the member the amount in money upon the
surrender of the certificates representing his shares.
 
     (9) If the company and a dissenting member fail, within the period of 30
days referred to in subsection (8), to agree on the price to be paid for the
shares owned by the member, within 20 days immediately following the date on
which the period of 30 days expires, the following shall apply:
 
          (a) the company and the dissenting member shall each designate an
     appraiser;
 
          (b) the 2 designated appraisers together shall designate a third
     appraiser;
 
          (c) the 3 appraisers shall fix the fair value of the shares owned by
     the dissenting member as of the close of business on the day prior to the
     date on which the vote of members authorizing the action was taken or the
     date on which written consent of members without a meeting was obtained,
     excluding any appreciation or depreciation directly or indirectly induced
     by the action or its proposal, and that value is binding on the company and
     the dissenting member for all purposes; and
 
          (d) the company shall pay to the member the amount in money upon the
     surrender by him of the certificates representing his shares.
 
     (10) Shares acquired by the company pursuant to subsection (8) or (9) shall
be cancelled but if the shares are shares of a surviving company, they shall be
available for reissue.
 
     (11) The enforcement by a member of his entitlement under this section
excludes the enforcement by the member of a right to which he might otherwise be
entitled by virtue of his holding shares, except that this section does not
exclude the right of the member to institute proceedings to obtain relief on the
ground that the action is illegal.
 
     (12) Only subsections (1) and (8) to (11) shall apply in the case of a
redemption of shares by a company pursuant to the provisions of Section 81 and
in such case the written offer to be made to the dissenting member pursuant to
subsection (8) shall be made within 7 days immediately following the direction
given to a company pursuant to Section 81 to redeem its shares.

                               PURCHASE AGREEMENT


     THIS PURCHASE AGREEMENT (this "Agreement") dated as of September 20, 1996
is among Genzyme Corporation ("Genzyme"), a Massachusetts corporation, Neozyme
II Acquisition Corp. (the "Purchaser"), a British Virgin Islands ("BVI")
international business company and a wholly-owned subsidiary of Genzyme, and
Neozyme II Corporation (the "Company"), a BVI international business company.

                                   BACKGROUND

     A. The respective Boards of Directors of Genzyme, the Purchaser and the
Company have duly approved the acquisition of the Company pursuant to the terms
of this Agreement.

     B. In furtherance of such acquisition, it is proposed that the Purchaser
will make a tender offer (the "Offer") to purchase all of the outstanding units
(the "Units"), each of which consists of one share of Callable Common Stock, par
value $1.00 per share, of the Company (individually, a "Share" and,
collectively, the "Shares") and Callable Warrants (the "Callable Warrants") to
purchase two shares of General Division Common Stock of Genzyme and .135 shares
of Tissue Repair Division Common Stock of Genzyme. The Shares included in the
Units represent all of the issued and outstanding capital stock of the Company.
The Offer will be at a price of $45.00 per Unit in cash and will be subject to
the Minimum Condition (as defined in ANNEX I hereto), and on the terms and
subject to the other conditions set forth in the Offer Documents (as defined in
Section 1.1(b)).

     C. If the Offer is consummated, but not all of the Units are tendered and
accepted, Genzyme has agreed to effect a transaction (as more fully described in
Section 2.1) in which Genzyme will acquire, directly or indirectly, all of the
remaining Shares of the Company in exchange for cash in an amount per Share
equal to $29.00 (the "Second Step Consideration"). The Callable Warrants
associated with each such Share shall remain outstanding following consummation
of the Second Step Transaction (as defined in Section 2.1). In order to effect
the Second Step Transaction as promptly as practicable following completion of
the Offer, the Board of Directors of the Company has duly authorized a merger
(the "Merger") of the Company with a wholly- owned subsidiary of the Purchaser
on the terms and subject to the conditions of this Agreement and pursuant to the
plan of merger set forth as ANNEX II hereto (the "Merger Plan") in accordance
with the applicable provisions of the BVI International Business Companies
Ordinance, 1984 (the "BVI Law"). At the request of Genzyme in accordance with
the terms of this Agreement, the Company will solicit the written consents of
its shareholders for the approval of the Merger Plan. At Genzyme's option and
subject to compliance with applicable laws, such solicitation may occur while
the Offer is pending or following its consummation.

     D. If the Offer is terminated because the Minimum Condition has not been
satisfied, upon the election and at the request of Genzyme in accordance with
Section 1.1(b)(ii) of this Agreement, the Company shall take all action
(coordinating the timing thereof with Genzyme and the Purchaser) necessary, in
accordance with applicable law and the Company's

                                      -1-

<PAGE>   2

Memorandum of Association and Articles of Association, to convene a meeting of
its shareholders to consider and vote upon the approval of the Merger Plan, or
to solicit the written consent of its shareholders to approve the Merger Plan.

     E. The Board of Directors of the Company, on the recommendation of a
special committee of the Board of Directors consisting of all of the directors
of the Company who are not officers or directors of Genzyme (the "Special
Committee"), has determined that the Offer and the Second Step Transaction are
fair to, and in the best interests of the holders of the Units and has duly
approved the Offer and the Second Step Transaction and resolved to recommend
acceptance of the Offer by the holders of the Units.

     Accordingly, in consideration of the mutual representations, warranties and
covenants contained herein, the parties hereto agree as follows:

                                  1. THE OFFER

     1.1. The Offer.
          ---------

          (a) Provided that this Agreement shall not have been terminated in
accordance with Section 8.1 hereof and nothing shall have occurred and be
continuing that would result in a failure to satisfy any of the conditions set
forth in ANNEX I hereto, the Purchaser shall, as soon as practicable after the
date hereof, and in any event within five business days of the day on which the
Purchaser's intention to make the Offer is publicly announced, which
announcement will be made promptly following the execution of this Agreement,
commence (within the meaning of Rule 14d-2(a) of the U.S. Securities Exchange
Act of 1934, as amended (the "Exchange Act")), the Offer for all Units, subject
to the Minimum Condition (as defined in ANNEX I hereto), at a price of $45.00
per Unit, net to the seller in cash, without interest thereon. The Purchaser
shall conduct the Offer in compliance in all material respects with applicable
laws and consummate the Offer, on the terms and subject to the conditions
thereof. Genzyme represents that it has, and will provide to the Purchaser on a
timely basis, the funds necessary to purchase the Units pursuant to the Offer
and to consummate the Second Step Transaction.

          (b) The Offer shall be made by means of the Offer Documents (as
defined below), which shall not contain any condition not set forth in ANNEX I
hereto and shall be open for a period of 21 business days (such 21st business
day being referred to herein as the "Initial Expiration Date"). Without the
consent of the Company, as approved by the Special Committee, the Purchaser
shall not amend or waive the Minimum Condition (as defined in ANNEX I hereto) or
the Majority Consent Condition (as defined below), extend the Offer, reduce the
maximum number of Units to be purchased, reduce the price to be paid per Unit
pursuant to the Offer or amend any other material term of the Offer in a manner
adverse to the holders of the Units; provided, however, that if, on the Initial
Expiration Date, the Minimum Condition has not been satisfied, the Purchaser
may, not later than 9:00 a.m., eastern time, on the next business day following
the Initial Expiration Date, elect either (x) to amend the Offer and, subject to
compliance with applicable laws, proceed in accordance with subsection (i) below
or (y) to terminate the Offer and, subject to compliance with applicable laws,
proceed in accordance with subsection (ii) below. If, on the Initial Expiration
Date, the Minimum Condition has not been satisfied and the Purchaser does not
elect to proceed pursuant to subsection (i) or (ii) below

                                     -2-
<PAGE>   3

within the time period and as described in the preceding sentence, then the
Company shall have the right to terminate this Agreement in accordance with
Section 8.1(b)(i) and Genzyme and the Purchaser shall have the right to
terminate this Agreement in accordance with Section 8.1(c)(i).

          (i)  If the Purchaser elects to amend the Offer and proceed under this
               subsection 1.1(b)(i), the Purchaser will (a) extend the Offer for
               a period not to exceed sixty days, (b) amend the Offer to delete
               the Minimum Condition, (c) amend the Offer to add the Majority
               Consent Condition (as defined below), and (d) amend the Offer
               Documents to reflect the foregoing and cause the dissemination of
               such revised documents in accordance with applicable laws. In
               such event, the Company shall promptly commence (coordinating the
               timing thereof with Genzyme and the Purchaser) to convene a
               meeting of its shareholders or solicit the written consent of its
               shareholders for approval of the Merger Plan, such solicitation
               or meeting to be conducted in accordance with applicable laws and
               the terms of this Agreement. The Majority Consent Condition shall
               mean that the sum of (a) the Shares included in the Units
               tendered and not withdrawn as of the new expiration date of the
               Offer (provided such Shares may be voted in favor of the Merger
               Plan at the meeting or pursuant to the consent solicitation by
               the Purchaser immediately after the purchase of the Units which
               include such Shares in the Offer by the Purchaser) plus (b) the
               number of Shares held by holders who have voted in favor of the
               Merger Plan at the meeting or pursuant to the consent
               solicitation as of the new expiration date of the Offer (but
               excluding any such Shares that would result in double counting
               with (a) above) represents not less than a majority of the Shares
               outstanding.

          (ii) If the Purchaser elects to terminate the Offer and proceed under
               this subsection 1.1(b)(ii), the Purchaser will promptly return
               all tendered Units. In such event, the Company shall promptly
               commence (coordinating the timing thereof with Genzyme and the
               Purchaser) to convene a meeting of its shareholders or solicit
               the written consent of its shareholders for approval of the
               Merger Plan, such solicitation or meeting to be conducted in
               accordance with applicable laws and the terms of this Agreement.

          (c) As soon as practicable on the date of commencement of the Offer,
the Purchaser shall file with the Securities and Exchange Commission (the
"Commission") with respect to the Offer (i) a Tender Offer Statement on Schedule
14D-1 (together with all amendments and supplements thereto, the "Schedule
14D-1"), (ii) a Rule 13e-3 Transaction Statement on Schedule 13E-3 (together
with all amendments and supplements thereto, the "Schedule 13E-3") and (iii) an
Issuer Tender Offer Statement on Schedule 13e-4 (together with all amendments
and supplements thereto, the "Schedule 13E-4"), which will contain an offer to
purchase and forms of the related letters of transmittal and summary
advertisement (the Schedule 14D-1, the Schedule 13E-3, the Schedule 13E-4, the
offer to purchase and such other documents, together with any supplements or
amendments thereto, are referred to herein collectively as the "Offer
Documents"), all of which Offer Documents will be subject to review

                                     -3-

by the Company prior to filing. Genzyme and the Purchaser shall provide the
Company and its counsel with a copy of any written comments or telephonic
notification of any verbal comments Genzyme or the Purchaser may receive from
the Commission or its staff with respect to the Offer Documents promptly after
the receipt thereof and shall provide the Company and its counsel with a copy of
any written responses thereto and telephonic notification of any verbal
responses thereto of Genzyme or the Purchaser or their counsel.

     1.2. Company Action
          --------------

          (a) In connection with the Offer, the Company will comply with the
requirements of Rule 14d-5(b) of the Exchange Act and will, or will cause its
agent to, mail, via first class mail, postage prepaid the Offer Documents and,
if applicable, the Proxy Statement (as defined in 1.2(c)) to the record holders
of the Units in accordance with Rule 14d-5(b). The Company will cooperate with
the Purchaser to the end that any additional Offer Documents furnished to it (or
its agent) are mailed as soon as practicable. The Purchaser shall pay all costs
and expenses of such mailing.

          (b) The Company represents and warrants that the Board of Directors of
the Company (the "Company's Directors"), on the recommendation of the Special
Committee, (i) has duly adopted and approved the Offer, the Second Step
Transaction, this Agreement and the transactions contemplated hereby and
thereby, (ii) has determined that the Offer and the Second Step Transaction are
fair to and in the best interests of the shareholders of the Company and (iii)
after consideration of its fiduciary duties under applicable laws, has resolved
to recommend acceptance of the Offer by holders of Units. The Company agrees to
file with the Commission as soon as reasonably practicable on the date of the
commencement of the Offer a Solicitation/Recommendation Statement on Schedule
14D-9 (together with all amendments and supplements thereto, the "Schedule
14D-9") and to disseminate the Schedule 14D-9 to the extent required by Rule
14d-9 under the Exchange Act and any other applicable U.S. federal securities
laws. Subject to the fiduciary duties of the Company's Directors, as advised by
counsel, the Offer Documents and the Schedule 14D-9 shall contain the
recommendation of the Company's Directors that the holders of Units accept the
Offer, and the Company hereby consents to the inclusion in the Offer Documents
of such recommendation. The Company shall provide Genzyme and its counsel with a
copy of any written comments or telephonic notification of any verbal comments
the Company may receive from the Commission or its staff with respect to the
Schedule 14D-9 promptly after the receipt thereof and shall provide Genzyme and
its counsel with a copy of any written responses thereto and telephonic
notification of any verbal responses thereto of the Company or its counsel.

          (c) At the request of Genzyme, the Company shall take all action
(coordinating the timing thereof with Genzyme and the Purchaser) necessary, in
accordance with applicable law and the Company's Memorandum of Association and
Articles of Association, to convene a meeting of its shareholders (the
"Shareholders' Meeting"), as promptly as practicable after the purchase of Units
pursuant to the Offer to consider and vote upon the approval of the Merger Plan,
or to solicit the written consent of its shareholders to approve the Merger Plan
(the "Consent Solicitation") promptly after such purchase or, promptly after the
request of Genzyme, after the commencement of the Offer and while it is pending
or following the termination of the Offer upon the election of Genzyme pursuant
to Section 1.1(b)(ii). If required by applicable

                                     -4-

law, the Company shall promptly prepare and file with the Commission, and use
its reasonable best efforts to have cleared by the Commission, a proxy, consent
solicitation or information statement relating to the Second Step Transaction
(the "Proxy Statement") in compliance with applicable law. Subject to the
fiduciary duties of the Company's Directors, as advised by counsel, the Proxy
Statement shall contain a statement as to the approval of the Merger Plan by the
Company's Board of Directors and the determination by the Company's Board of
Directors that the Second Step Transaction is fair to and in the best interests
of the holders of the Shares, and the Company hereby consents to the inclusion
in the proxy, consent solicitation or information statement of such statement.

          (d) The Special Committee and the Company's Directors have received
the written opinion of Hambrecht & Quist LLC (the "Financial Adviser") that, on
the basis of and subject to the matters set forth therein, the cash
consideration of $45.00 per Unit to be received by holders of the Units pursuant
to the Offer is fair to the holders of the Units from a financial point of view
and the Second Step Consideration to be received by the holders of the Shares
pursuant to the Second Step Transaction is fair to the holders of the Shares
from a financial point of view (the "Fairness Opinion"). The Company has
provided Genzyme and the Purchaser with a copy of the Fairness Opinion for
inclusion in the Offer Documents.

     1.3. Directors.
          ---------

          (a) Promptly upon the acceptance for payment of and payment by the
Purchaser for any Units pursuant to the Offer, and from time to time thereafter
as Units are accepted for payment and paid for by the Purchaser, subject to
compliance with Section 14(f) of the Exchange Act, the Purchaser shall be
entitled to designate such number of the Company's Class A Directors, rounded to
the nearest whole number, as will give the Purchaser representation on the
Company's Board of Directors equal to at least that number of directors which
equals the product of the total number of the Company's Directors (after giving
effect to the directors elected pursuant to this sentence) multiplied by the
percentage that such number of Units so accepted for payment and paid for by the
Purchaser bears to the number of Units outstanding, and the Company shall,
promptly following any such designation by the Purchaser, take such actions as
are necessary to cause the Purchaser's designees to be so elected, including
increasing the size of the Board of Directors or securing the resignations of
incumbent directors or both; provided, however, that notwithstanding the
Purchaser's right to designate certain of the Company's Directors, until the
Effective Date (as defined in Section 2.3 hereof), the Company's Class A
Directors shall include at least two directors who are directors on the date
hereof and who are not officers or directors of Genzyme or the Purchaser (the
"Independent Directors"); provided further that, if the number of Independent
Directors shall be reduced below two for any reason whatsoever, any remaining
Independent Director shall be entitled to designate a person who is not an
officer or director of Genzyme or the Purchaser to fill such vacancy and such
person shall be deemed to be an Independent Director for purposes of this
Agreement or, if no Independent Directors then remain, the other directors shall
designate two persons to fill such vacancies who shall not be designees,
shareholders, directors, officers or affiliates of Genzyme or the Purchaser, and
such persons shall be deemed to be Independent Directors for purposes of this
Agreement. Subject to applicable law, the Company shall take all action
necessary to effect the election of directors as provided in this Section
1.3(a), including mailing to its shareholders the information required by
Section 14(f) of the Exchange Act and Rule 14f-1

                                     -5-
<PAGE>   6

promulgated thereunder. Genzyme and the Purchaser shall supply to the Company
and be solely responsible for any information with respect to them and their
nominees, officers, directors and affiliates required by Section 14(f) and Rule
14f-1.

          (b) Notwithstanding anything in this Agreement to the contrary,
subject to the terms of the Company's Memorandum of Association and Articles of
Association, in the event that the Purchaser's designees are appointed or
elected as Company Directors, after the acceptance for payment of Units pursuant
to the Offer and prior to the Effective Date, the affirmative vote of a majority
(or, if there are only one or two Independent Directors, the single or unanimous
vote, as the case may be) of the Independent Directors (who shall act as an
independent committee of the Board of Directors for this purpose) shall be
required, and alone shall be sufficient, to (i) amend or terminate this
Agreement by the Company, (ii) exercise or waive any of the Company's rights or
remedies hereunder, (iii) extend the time for performance of Genzyme's and the
Purchaser's respective obligations hereunder, or (iv) approve any other action
by the Company that the Independent Directors determine could adversely affect
the interests of the shareholders of the Company (other than Genzyme, the
Purchaser and their affiliates) with respect to the transactions contemplated
hereby.

                         2. THE SECOND STEP TRANSACTION

     2.1. Consummation of the Second Step Transaction.
          -------------------------------------------

          (a) If the Offer is consummated and 90% or more of the Units are
tendered and accepted, the Purchaser will, as soon as practicable following
satisfaction or waiver of the conditions set forth in Section 7.1 hereof, either
(i) effect a merger of the Company into the Purchaser pursuant to Section 77 of
the BVI Law (the "Short Form Merger") or (ii) cause the Company to redeem all
Shares not held by the Purchaser pursuant to Section 81 of the BVI Law (the
"Redemption").

          (b) If the Offer is consummated and less than 90% but more that 50% of
the Units are tendered and accepted, the Purchaser will own a majority of the
Shares and will vote those shares in favor of and will effect, as soon as
practicable following satisfaction or waiver of the conditions set forth in
Section 7.1 hereof, the Merger.

          (c) If the Offer is not consummated on the Initial Expiration Date
because the Minimum Condition is not met and the Purchaser elects to proceed as
described in Section 1.1(b)(i), the Company, the Purchaser and Genzyme shall
take the actions set forth in Section 1.1(b)(i). As soon as practicable
following satisfaction of the Majority Consent Condition and satisfaction or
waiver of the conditions set forth in Annex I (other than the Minimum Condition)
and Section 7.1, the Purchaser will purchase all Units validly tendered and not
withdrawn, vote the Shares thus acquired in favor of the Merger Plan and effect
the Merger.

          (d) If the Offer is not consummated because the Minimum Condition is
not met and the Purchaser elects to proceed as described in Section 1.1(b)(ii),
the Company, the Purchaser and Genzyme shall take the actions set forth in
Section 1.1(b)(ii). As soon as practicable following satisfaction or waiver of
the conditions set forth in Article 7 hereof, the Purchaser will effect the
Merger.

                                     -6-

          (e) The Short Form Merger, the Redemption and the Merger referred to
in subsections (a) - (d) above are referred to herein as the "Second Step
Transaction." The date of consummation of the Second Step Transaction is
referred to herein as the "Effective Date."

     2.2. SECOND STEP CONSIDERATION.

          (a) On the Effective Date, as a result of the Short Form Merger, if
applicable. the Company will be merged with and into the Purchaser, with the
Purchaser as the surviving corporation and:

               (i) The holder of each Share issued and outstanding immediately
prior to the Effective Date (other than Shares owned by Genzyme, the Purchaser,
the Company or any direct or indirect subsidiary of any of them and any
Dissenting Shares (as defined in subsection (d) below)) shall be entitled to
receive an amount in cash per Share equal to the Second Step Consideration.

               (ii) Shares owned by Genzyme, the Purchaser or the Company or any
direct or indirect subsidiary of any of them shall be cancelled.

          (b) On the Effective Date, as a result of the Redemption, if
applicable, the holder of each Share issued and outstanding immediately prior to
the Effective Date (other than Shares owned by the Purchaser and any Dissenting
Shares) shall be entitled to receive an amount in cash per Share equal to the
Second Step Consideration.

          (c) On the Effective Date, as a result of the Merger pursuant to
Sections 2.1(b)-(d), if applicable, a wholly-owned subsidiary of the Purchaser
will be merged with and into the Company, with the Company as the surviving
corporation and:

               (i) The holder of each Share issued and outstanding immediately
prior to the Effective Date (other than Shares owned by Genzyme, the Purchaser,
the Company or any direct or indirect subsidiary of any of them and any
Dissenting Shares) shall be entitled to receive an amount in cash per Share
equal to the Second Step Consideration.

               (ii) Shares owned by Genzyme, the Purchaser or the Company or any
direct or indirect subsidiary of any of them shall be cancelled.

               (iii) Each issued and outstanding share of capital stock of the
subsidiary of the Purchaser that is a party to the Merger Plan shall be
converted into one fully paid and nonassessable share of common stock of the
surviving corporation.

          (d) (i) In the case of the Short Form Merger, the Redemption or the
Merger, shares of capital stock of the Company held by a shareholder who has
properly exercised dissenters rights with respect thereto in accordance with
Section 83 of the BVI Law (collectively, the "Dissenting Shares") shall not be
converted into the Second Step Consideration. From and after the Effective Date,
a shareholder who has properly exercised such dissenters' rights shall no longer
retain any rights of a shareholder of the Company, except those provided under
the BVI Law. If after the Effective Date such holder withdraws or loses his
right to demand

                                     -7-

<PAGE>   8



payment for his Shares, such Shares shall be treated as if they had been
converted as of the Effective Date into the right to receive the Second Step
Consideration payable in respect of such Shares pursuant to Section 2.2(a)(i).

          (ii) The Company shall give Genzyme (i) prompt notice of any demands
for payment, or notices of intent to demand payment, with respect to any shares
of capital stock of the Company, any withdrawal of any such demands and any
other instruments served pursuant to the BVI Law and received by the Company and
(ii) the right to participate in all negotiations and proceedings with respect
to any such demands. The Company shall cooperate with Genzyme concerning, and
shall not, except with the prior written consent of Genzyme, voluntarily make
any payment with respect to, or offer to settle or settle, any such demands.

     2.3. Exchange of Certificates.
          -------------------------
          (a) Genzyme shall authorize one or more persons to act as Payment
Agent for the Second Step Consideration (the "Payment Agent"). Genzyme shall
deposit with the Payment Agent in trust for the benefit of the holders of
certificates representing Shares converted pursuant to Section 2.2(a)(i), on or
prior to the Effective Time, immediately available funds in an amount equal to
the product of the Second Step Consideration multiplied by the number of Shares
entitled to payment pursuant to Section 2.2(a)(i). As soon as practicable after
the Effective Time, Genzyme shall cause the Payment Agent to mail to all former
holders of record of Shares instructions for surrendering their certificates
representing Shares in exchange for the Second Step Consideration. Upon
surrender of a Share certificate for cancellation to the Payment Agent, the
Payment Agent shall pay to the holder of such certificate the Second Step
Consideration multiplied by the number of Shares represented by such
certificate, and the certificate so surrendered shall forthwith be canceled.
Notwithstanding the foregoing, if delivery of the Second Step Consideration is
to be made to any person other than the person in whose name the certificate
surrendered is registered, it shall be a condition of such delivery that the
certificate so surrendered shall be properly endorsed or otherwise in proper
form for transfer and that the person requesting such delivery shall pay any
transfer or other taxes required by reason of such delivery or establish to the
satisfaction of Genzyme that such tax has been paid or is not applicable.
Furthermore, neither Genzyme nor any affiliate of Genzyme shall be liable to a
holder of Shares for any Second Step Consideration delivered to a public
official pursuant to applicable abandoned property, escheat and similar laws.
After the Effective Time, there shall be no transfers of the Shares on the stock
transfer books of the Company.

          (b) The Payment Agent shall make the payments referred to in Section
2.2(a)(i) out of the funds supplied by Genzyme. Promptly following the date that
is six months after the Effective Date, the Payment Agent shall, upon request by
Genzyme, deliver to Genzyme all cash, certificates and other documents in its
possession relating to the transactions described in this Agreement, and the
Payment Agent's duties shall terminate. Thereafter, each holder of a certificate
formerly representing a Share may surrender such certificate to Genzyme and
(subject to applicable abandoned property, escheat and similar laws) receive in
exchange therefor the Second Step Consideration, without any interest thereon
but shall have no greater rights against Genzyme than may be accorded to general
creditors of Genzyme under applicable law.

          (c) From and after the Effective Date, holders of certificates
theretofore evidencing Shares shall cease to have any rights as shareholders of
the Company, except as provided herein or by law. Until surrendered in
accordance with the provisions of this Section, each Share certificate (other
than for Dissenting Shares) shall represent for all purposes only the right to
receive the Second Step Consideration multiplied by the number of Shares
represented by such certificate.

     2.4. CALLABLE WARRANTS. On the Effective Date, the Callable Warrants
associated with the Shares converted into the right to receive the Second Step
Consideration will become exercisable in accordance with its terms and at the
exercise price computed as stated therein. On the day following the Effective
Date, such Callable Warrants will separate and be transferable separately from
the right to receive the Second Step Consideration on account of the Shares.

        3. REPRESENTATIONS AND WARRANTIES OF THE PURCHASER AND GENZYME

     The Purchaser and Genzyme represent and warrant to the Company as follows:

result in a breach of, any provision of the charter or bylaws of Genzyme or the
Purchaser, (b) violate, conflict with or result in a default (or give rise to
any right of termination, cancellation or acceleration) under, any of the terms,

to the extent that any of them shall have become false or misleading (provided
that, with respect to any false or misleading information provided by or on
behalf of the Company and included in the Offer Documents, the Company shall
have provided Genzyme and the Purchaser with correct information) and Genzyme
and the Purchaser shall take all steps necessary to cause the Offer Documents as

U.S. federal securities laws.

federal, state, local or foreign tax liability; and

     (c) The Company shall not agree in writing or otherwise, to take any of the

I prior to consummation of the Offer and, thereafter, Article 7 hereof.

     5.2. COMMISSION FILINGS AND OTHER MATTERS. The Company shall promptly

to take such actions as it may deem appropriate to reduce or eliminate any
discretionary spending by the Company or by Genzyme on behalf of the Company not
contractually committed to with a person or entity that is not a party to this

Agreement and no party may recover any such fees and expenses from any other
party upon any termination of this Agreement except as provided in Article 8.

     6.3. ADDITIONAL AGREEMENTS. Subject to the terms and conditions herein
provided, each of the parties hereto agrees to use all reasonable efforts to
consummate and make effective as promptly as practicable the transactions
contemplated by the Offer and this Agreement, and to cooperate with each of the

obtain all necessary waivers, consents and approvals from other parties to

as are required by law; (C) to lift or rescind any injunction or restraining
order or other order adversely affecting the ability of the parties to

Each of the Company, Genzyme and the Purchaser further covenants and agrees

Company, Genzyme and the Purchaser shall use their respective reasonable best
efforts (which shall not be construed to require the payment of any money to a
third party or the divestiture of any business or assets) to prevent the entry
of an injunction or other order adversely affecting the ability of the parties
to consummate the transactions contemplated hereby .

     6.4. NO SOLICITATION.

          (a) The Company shall not, directly or indirectly, through any
officer, director, employee, financial advisor, representative or agent of the
Company, (i) solicit or initiate any inquiries or proposals regarding a merger,
consolidation, business combination, sale of substantial assets, sale of shares
of capital stock (including without limitation by way of a tender offer) or
similar transactions involving the Company, other than the transactions
contemplated by this Agreement (any of the foregoing inquiries or proposals
being referred to in this Agreement as an "Acquisition Proposal"), (ii) engage
in negotiations or discussions concerning, or provide any non-public information
to any person or entity relating to, any Acquisition Proposal, or (iii) agree
to, approve or recommend any Acquisition Proposal; provided, however, that
nothing contained in this Agreement shall prevent the Company, the Company's
Directors or the Special Committee (through any officer, director, employee,
financial advisor, representative or agent) from (A) engaging in negotiations or
discussions in response to an inquiry that was not solicited after the date
hereof; (B) furnishing non-public information to any person or entity in
connection with an unsolicited written Acquisition Proposal by such person or
entity or recommending an unsolicited written Acquisition Proposal to the
shareholders of the Company, if and only to the extent that (1) the Company's
Directors or the Special Committee, as the case may be, believe in good faith
after consultation with its financial advisor that the party requesting such
non-public information or making such Acquisition Proposal is capable of
financing a transaction more favorable to the Company's shareholders from a
financial point of view than the transaction contemplated by this Agreement and
the Company's Directors or the Special Committee, as the case may be, determine
in good

                                     -14-
<PAGE>   15

faith after consultation with outside legal counsel that such action is
necessary to comply with their fiduciary duties to shareholders under applicable
law and (2) prior to furnishing such non-public information to such person or
entity, the Company's Directors or the Special Committee, as the case may be,
receive from such person or entity an executed confidentiality agreement on
customary terms; or (C) complying with Rule 14e-2 promulgated under the Exchange
Act with regard to an Acquisition Proposal.

          (b) The Company shall notify Genzyme in writing in reasonable detail
within 24 hours after receipt by the Company (or its advisors) of any written
Acquisition Proposal or any written request for non-public information to which
the Company intends to affirmatively respond.

          (c) Genzyme and the Company acknowledge and confirm that neither (x)
Section 2.3 ("Restrictions Upon Use of Licensed Technology") of the Technology
License Agreement dated April 28, 1992 between them, nor (y) Section 12 of the
Company's Memorandum of Association, is intended or shall be deemed, to prohibit
or restrict any discussions, negotiations or other activity by the Company
permitted by subsection (a) above.

     6.5. NOTIFICATION OF BREACH. The Company shall give prompt notice to
Genzyme, and Genzyme and the Purchaser shall give prompt notice to the Company,
of the occurrence or failure to occur of any event which occurrence or failure
to occur causes (x) any representation or warranty made by it in this Agreement
to be untrue or inaccurate in any material respect at any time from the date
hereof to the date of purchase of, and payment for, Units pursuant to the Offer,
or (y) any material failure to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by it under this Agreement; provided,
however, that no such notification shall be deemed to cure any breach or
otherwise affect the representations or warranties of such party or the
conditions to the obligations of the parties hereunder.

     6.6. ACCESS TO INFORMATION. Except as prohibited by BVI law, the Company
shall afford to Genzyme and to the officers, employees and agents of Genzyme
reasonable access during regular business hours, from the date hereof to the
Effective Date, to the Company's officers, employees, agents, properties, books,
records and contracts, and shall furnish Genzyme all financial, operating and
other data and information as Genzyme, through its officers, employees or
agents, may reasonably request; provided, however, that such access shall not
unreasonably interfere with any of the operations of the Company.

     6.7. DIRECTORS' AND OFFICERS' INDEMNIFICATION AND INSURANCE.

          (a) As of the Effective Date, proper provision will be made so that
any affiliate of Genzyme that succeeds to the assets and liabilities of the
Company, or at Genzyme's option, Genzyme, shall assume all of the obligations of
the Company under the indemnification agreements between the Company and the
Independent Directors as in effect on the date of this Agreement and, if amended
prior to the Effective Date, on the Effective Date. In the event of a transfer
by such successor entity of all or substantially all of its assets or a merger
or consolidation in which such entity is not the surviving entity, proper
provision will also be made so that the successors and assigns of such entity,
or at Genzyme's option, Genzyme, shall assume the obligations of the Company
under such agreements. In addition, the Company and,

                                     -15-

<PAGE>   16

from and after consummation of the Offer or, if the Purchaser elects to proceed
under Section 1.1(b)(ii), the Merger, Genzyme shall, to the fullest extent
permitted by applicable law, indemnify and hold harmless each present and former
director or officer of the Company (collectively, "Indemnified Parties") against
all costs and expenses (including attorneys' fees) judgments, fines, losses,
claims, damages, liabilities and settlement amounts paid in connection with any
claim, action, suit, proceeding or investigation (whether arising before or
after the consummation of the Offer) arising out of any act or omission in their
capacity as officer, director or employee of the Company (and shall pay any
expenses in advance of the final disposition of such action or proceeding to
each Indemnified Party to the fullest extent permitted by law). If
indemnification is sought hereunder by any Indemnified Party, then such
Indemnified Party shall promptly notify Genzyme in writing of the claim for
which indemnification is sought; provided, however, that the failure to so
notify Genzyme shall not relieve Genzyme from any liability unless and to the
extent that such failure results in a forfeiture by the Indemnified Party of
substantive rights or defenses. Following such notification, Genzyme may elect
to assume the defense of such claim, and, upon such election, Genzyme shall not
be liable for any legal costs subsequently incurred by such Indemnified Party
(other than reasonable costs of investigation) in connection therewith, unless
Genzyme has failed to provide counsel reasonably satisfactory to such
Indemnified Party in a timely manner or counsel that has been provided by
Genzyme reasonably determines that its representation of such Indemnified Party
would present it with a conflict of interest. The Indemnified Party will
cooperate with Genzyme in the investigation and defense of any claim and shall
not settle any claim without Genzyme's prior written consent.

          (b) Genzyme shall maintain in effect for three years from the
Effective Date, if available, directors' and officers' liability insurance
policies covering the directors and officers of the Company, with coverages and
other terms at least as favorable as is currently in effect; provided, however,
that Genzyme shall not be required to spend more than an amount per year equal
to 150% of the current annual premium paid by the Company for such insurance.
Following such three year period, and until the sixth anniversary of the
Effective Date, Genzyme will assume the indemnification obligations of the
Company under the indemnification agreements referred to in subsection (a) above
to the extent it has not already done so.

     6.8. GENZYME'S GUARANTY. Genzyme unconditionally guarantees the Purchaser's
obligations (and the obligations of any other affiliate of Genzyme that is a
party to the Merger Plan) under this Agreement and agrees to be primarily liable
for any breach of this Agreement by the Purchaser (or such other affiliate of
Genzyme).

                                  7. CONDITIONS

     7.1. CONDITIONS TO OBLIGATION OF EACH PARTY TO EFFECT THE SECOND STEP
TRANSACTION. The respective obligations of each party to effect the Second Step
Transaction shall be subject to the fulfillment at or prior to the Effective
Date of each of the following conditions:

          (a) the Purchaser shall have made the Offer on the terms and
conditions set forth therein and shall have purchased, or caused to be
purchased, all Units validly tendered and not withdrawn pursuant to the Offer;
provided, however, this condition shall not be applicable to the obligations of
Genzyme or the Purchaser if, in breach of this Agreement or the terms of the

                                     -16-

<PAGE>   17

          (b) the Merger Plan shall have been approved and adopted by the
requisite vote or consent, if any, of the shareholders of the Company required
by the BVI Law and the Company's Memorandum of Association and Articles of
Association; and

          (c) no preliminary or permanent injunction or other order, decree or
ruling issued by a court of competent jurisdiction or by a governmental or
regulatory body nor any statute, rule, regulation or order promulgated or
enacted by any governmental body shall be in effect, which would make the
acquisition by Genzyme or the Purchaser of the Shares illegal or otherwise
prevent the consummation of the Second Step Transaction.

     7.2. CONDITIONS TO OBLIGATION OF THE PURCHASER TO EFFECT A MERGER PURSUANT
TO SECTION 1.1(b)(ii). In addition to the fulfillment of the condition set forth
in subsection 7.1(b), the Purchaser shall not be obligated to effect a Merger
pursuant to Section 1.1(b)(ii) if on or before the Effective Date any of the
following shall occur or shall be determined by the Purchaser to have occurred
and remain in effect:

          (a) except for matters which affect generally the economy or the
industry in which the Company is engaged and except for continued losses
incurred by the Company as a result of its operations and continued depletion of
its cash resources in the ordinary course of business or consistent with the
annual workplan currently in effect, any change shall have occurred in the
business, properties, assets, liabilities, capitalization, stockholders equity,
financial condition, operations, licenses or franchises or results of operations
of the Company which has a Material Adverse Effect; or

          (b) there shall have been instituted or be pending any action,
proceeding, application or counterclaim before any court or governmental or
regulatory body which (i) challenges the validity of or seeks to restrain the
consummation of or to impose any material limitation, on any transaction

                      8. TERMINATION, AMENDMENT AND WAIVER

     8.1. TERMINATION. This Agreement may be terminated at any time prior to the
Effective Date, as follows:

          (a) Subject to Section 1.3(b), by mutual written consent of the Boards

Special Committee); or

          (b) By the Company upon approval of the Special Committee:

               (i) if (A) the Purchaser shall have terminated the Offer without
the purchase of any Units thereunder; or (B) the Purchaser shall not have paid
for all Units validly tendered pursuant to the Offer and not withdrawn within 90
days after the commencement of the Offer, unless such termination of the Offer
or failure to pay for Units shall have been caused by or resulted from (a) the
failure of the Company to perform in any material respect any of its covenants
or agreements contained in this Agreement, (b) the material breach by the
Company of any of its representations or warranties contained in this Agreement,
or (c) an election by the Purchaser pursuant to Section 1.1(b)(ii) of this
Agreement to terminate the Offer; or

               (ii) if the Effective Date shall not have occurred on or before
the six-month anniversary of the date of this Agreement due to a failure of any
of the conditions to the obligation of the Company to effect the Second Step
Transaction set forth in Section 7.1 or if the Purchaser has elected to proceed
under Section 1.1(b)(i), if the Effective Date shall not have occurred on or
before the six-month anniversary of the date of this Agreement; or

               (iii) prior to the purchase of any Units pursuant to the Offer,
or the Effective Date if the Purchaser has elected to proceed under Section
1.1(b)(ii), if the Purchaser or Genzyme has materially failed to perform any of
its obligations under this Agreement and such nonperformance has a material
adverse effect on the Purchaser's or Genzyme's ability to consummate the Offer
or the Second Step Transaction; or

               (iv) if, in the event that the Minimum Condition shall not have
been satisfied on the Initial Expiration Date and the Purchaser shall have
amended the Offer or terminated the Offer pursuant to the proviso in the second
sentence of Section 1.1(b), the Purchaser has materially failed to perform any
of its obligations under Section 1.1(b); or

          (v) if, prior to the purchase of Shares pursuant to the Offer, or the
Effective Date if the Purchaser has elected to proceed under Section 1.1(b)(ii),
the Special Committee shall have withdrawn or modified its approval or
recommendation of the Offer or this Agreement in order to approve the execution
by the Company of a definitive agreement providing for the acquisition of the
Company or substantially all of its assets or a merger or other business
combination or in order to approve a tender offer for all of the Shares or Units
by a third party, in any case, as determined by the Special Committee, on terms
more favorable to the Company's stockholders than the Offer (a "Superior
Transaction"), provided, that (i) the Company shall have provided Genzyme with
at least five business days' written notice of such Superior

                                     -18-

<PAGE>   19

Transaction, including a copy of the proposed agreement and (ii) the Company
shall not have violated Section 6.4 in connection with such Superior
Transaction.

          (c) By Genzyme or the Purchaser:

               (i) if, due to an occurrence that would result in a failure to
satisfy any condition set forth in Annex I or the Majority Consent Condition if
the Purchaser has elected to proceed pursuant to Section 1.1(b)(i), the
Purchaser shall have (A) failed to commence the Offer within 5 business days of
the date on which the Purchaser's intention to make the Offer is publicly
announced; (B) terminated the Offer without the purchase of any Units
thereunder; or (C) failed to pay for all Units validly tendered pursuant to the
Offer and not withdrawn within 90 days after commencement of the Offer, unless
such failure or termination shall have been caused by or results from (x) the
failure of Genzyme or the Purchaser to perform in any material respect any of
its covenants or agreements contained in this Agreement, (y) the material breach
by Genzyme or the Purchaser of any of its representations or warranties
contained in this Agreement, or (z) the Purchaser's election to proceed pursuant
to Section 1.1(b)(ii); or

               (ii) if the Effective Date shall not have occurred on or before
the six-month anniversary of the date of this Agreement due to (i) a failure of
any of the conditions to the obligations of Genzyme or the Purchaser to effect
the Second Step Transaction set forth in Section 7.1, or (ii) in the event that
the Purchaser has elected to proceed under Section 1.1(b)(ii), a failure of any
of the conditions to the obligations of Genzyme or the Purchaser to effect the
Second Step Transaction set forth in Section 7.2; or

               (iii) if, prior to the purchase of Units pursuant to the Offer,
or the Effective Date if the Purchaser has elected to proceed under Section
1.1(b)(ii), the Company's Directors shall have publicly withdrawn or modified in
a manner adverse to the Purchaser their approval or recommendation of the Offer
or this Agreement or recommended acceptance of a Superior Transaction or shall
have resolved to do any of the foregoing.

     8.2. EFFECT OF TERMINATION. In the event of the termination of this
Agreement as provided in Section 8.1, all obligations and agreements of the
parties set forth in this Agreement shall forthwith terminate and be of no
further force or effect, and there shall be no liability on the part of Genzyme,
the Purchaser or the Company hereunder except (a) as provided in Sections 8.3
and 8.4 and (b) that the foregoing shall not relieve any party for liability for
any breach of this Agreement occurring prior to such termination.

     8.3. ANCILLARY AGREEMENTS. In the event of any termination of this
Agreement (x) by the Company pursuant to Section 8.1(b)(v) or by Genzyme or the
Purchaser pursuant to Section 8.1(c)(iii), in either case as a result of a
Superior Transaction in connection with which the Company shall not have
violated Section 6.4, or (y) by Genzyme or the Purchaser pursuant to Section
8.1(c)(i), unless such termination is based upon the failure of the Company to
perform in any material respect of its covenants or agreements contained in this
Agreement, Genzyme agrees that, effective upon consummation of a Superior
Transaction, it shall, at the Company's request:


                                      -19-

applicable provisions of the Company's Memorandum of Association;

          (b) terminate the Purchase Option Agreement dated as of April 28, 1992

          (c) consent to the assignment by the Company of the Technology License
Agreement dated as of April 28, 1992 between Genzyme and the Company;

               (i) the Research and Development Agreement between Genzyme and
               the Company;

               (ii) the Services Agreement between Genzyme Limited (a subsidiary

               (iii) the Administrative Agreement between Genzyme and the
               Company.

The termination of any of the foregoing agreements pursuant to this Section 8.3

survives termination of such agreement.

     8.4. TERMINATION FEE. In consideration of Genzyme's agreement set forth in
Section 8.3 and its expenses incurred in connection with the transactions
contemplated by this Agreement, in the event of the termination of this
Agreement (A) by the Company pursuant to Section 8.1(b)(v) or (B) by Genzyme or
the Purchaser pursuant to (x) Section 8.1(c)(iii) or (y) Section 8.1(c)(i) or

any material respect any of its covenants or agreements contained in this
Agreement, the Company shall pay Genzyme a termination fee of $500,000 upon
consummation of any Superior Transaction.

     8.5. AMENDMENT. This Agreement may not be amended except, subject to
Section 1.3, by action of the Board of Directors of each of the parties hereto
set forth in an instrument in writing signed on behalf of each of the parties

after any special meeting or written action of the shareholders of the Company
to approve the Second Step Transaction, any party hereto, subject to Section
1.3(b), by action taken by its Board of Directors (and, in the case of the
Company, subject to the approval of the Special Committee), may (i) extend the
time for the performance of any of the obligations or other acts of any other
party hereto or (ii) subject to the second sentence of Section 1.1(b) and the

     9.5. INTERPRETATION. When a reference is made in this Agreement to
subsidiaries of Genzyme, the Purchaser or the Company, the word "subsidiaries"
means any corporation more than 50 percent of whose outstanding voting
securities, or any partnership, joint venture or other entity more than 50
percent of whose total equity interest, is directly or indirectly owned by
Genzyme, the Purchaser or the Company, as the case may be; and the word
"affiliates" shall have the meaning assigned to such term under Rule 405 of the
Securities Act. For purposes of this Agreement, the Company shall not be deemed
to be an affiliate or subsidiary of Genzyme or the Purchaser.

     9.6. REPRESENTATIONS AND WARRANTIES, ETC. The respective representations
and warranties of the Company, Genzyme and the Purchaser contained herein shall
expire upon consummation of the Offer. This Section 9.6 shall have no effect
upon any other obligation of the parties hereto, whether to be performed before
or after the consummation of the Offer.

     9.7. MISCELLANEOUS. This Agreement (i) constitutes the entire agreement and
supersedes all other prior agreements and undertakings, both written and oral,
among the parties, or any of them, with respect to the subject matter hereof;
(ii) is not intended to confer upon any other person any rights or remedies
hereunder, create any agreement of employment with any person or otherwise
create any third-party beneficiary hereto, except for the provisions of Section
6.7 (which provisions are intended to be for the benefit of the persons referred
to therein and may be enforced by such persons); (iii) shall not be assigned
except that the Purchaser may assign its rights and obligations to Genzyme or to
one or more direct or indirect wholly-owned subsidiaries of Genzyme which in a
written instrument shall make all the representations and warranties of the
Purchaser set forth herein and shall agree to assume all of the Purchaser's
obligations hereunder and be bound by all of the terms and conditions of this
Agreement; provided, however, that no such assignment shall relieve Genzyme or
the Purchaser of its obligations hereunder; and (iv) shall be governed in all
respects, including validity, interpretation and effect, by the internal laws of
the Commonwealth of Massachusetts, without giving effect to the principles of
conflict of laws thereof. Only the Purchaser (or Genzyme or a direct or indirect
wholly-owned subsidiary of Genzyme to which the Purchaser assigns such rights
and obligations) may commence the Offer or the purchase of Shares thereunder.

     9.8. VALIDITY. The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of any other
provisions of this Agreement, which shall remain in full force and effect.

     9.9. COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, and all of which
together shall constitute one and the same instrument.

     9.10. SECTION HEADINGS. The section headings in this Agreement are for
convenience of reference only and are not intended to affect the meaning or
interpretation of this Agreement.

connection with such transactions; or

     (c) any statute, regulation, order or injunction shall have been enacted,

value, of Merger Corp. issued and outstanding immediately prior thereto shall,
by virtue of the Merger and without the surrender of stock certificates or any

following securities:

               (i) Each Share issued and outstanding immediately prior to the

               (ii) Each Share issued and outstanding immediately prior to the
Effective Date and owned by Genzyme Corporation ("Genzyme"), a Massachusetts

     (a)  Upon surrender of the Share certificate for cancellation to the
Payment Agent selected by Genzyme, the Payment Agent shall pay to the holder of
such certificate the Merger Consideration multiplied by the number of Shares
represented by such certificate, and the certificate so surrendered shall
forthwith be canceled. Notwithstanding the foregoing, if delivery of the Merger
Consideration is to be made to any person other than the person in whose name
the certificate surrendered is registered, it shall be a condition of such
delivery that the certificate so surrendered shall be properly endorsed or
otherwise in proper form for transfer and that the person requesting such

shall terminate. Thereafter, each holder of a certificate formerly representing
a Share may surrender such certificate to Genzyme and (subject to applicable
abandoned property, escheat and similar laws) receive in exchange therefor the
Merger Consideration, without any interest thereon but shall have no greater 
rights against Genzyme than may be accorded to general creditors of Genzyme 
under applicable law.

GENZYME CORPORATION AND SUBSIDIARIES

         REPORT OF INDEPENDENT ACCOUNTANTS

         To the Board of Directors and Stockholders of GENZYME CORPORATION:

                  We have audited the accompanying consolidated balance sheets
         of Genzyme Corporation and Subsidiaries as of December 31, 1995 and
         1994 and the related consolidated statements of operations, cash flows
         and stockholders' equity and the consolidated financial statement
         schedule for each of the three years in the period ended December 31,
         1995. The consolidated financial statements and financial statement
         schedule are the responsibility of the Company's management. Our
         responsibility is to express an opinion on these consolidated financial
         statements and financial statement schedule based on our audits.

                  We conducted our audits in accordance with generally accepted
         auditing standards. Those standards require that we plan and perform
         the audit to obtain reasonable assurance about whether the financial
         statements are free of material misstatement. An audit includes
         examining, on a test basis, evidence supporting the amounts and
         disclosures in the financial statements. 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 consolidated financial statements referred
         to above present fairly, in all material respects, the consolidated
         financial position of Genzyme Corporation and Subsidiaries as of
         December 31, 1995 and 1994 and the consolidated results of their
         operations and their cash flows for each of the three years in the
         period ended December 31, 1995, in conformity with generally accepted
         accounting principles. In addition, in our opinion, the consolidated
         financial statement schedule taken as a whole presents fairly, in all
         material respects, the information required to be included therein.

                      GENZYME CORPORATION AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE A  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Business: Genzyme Corporation (the "Company" or "Genzyme"), is a
diversified human healthcare business with product development, manufacturing
and marketing capabilities in therapeutic and diagnostic products,
pharmaceuticals, diagnostic services and tissue repair.

         Basis of Presentation: The approval effective December 16, 1994 (the
"Effective Date") by the stockholders of Genzyme of the Genzyme Stock Proposal
as described in Genzyme's Prospectus/Proxy Statement dated November 10, 1994
resulted in the redesignation of Genzyme's common stock. The outstanding shares
of Genzyme common stock were redesignated as General Division Common Stock
("General Division Stock") on a share-for-share basis and a second class of
common stock, designated as Tissue Repair Division Common Stock ("TR Stock") was
distributed on the basis of .135 of one share of TR Stock for each share of
Genzyme's common stock. General Division Stock and TR Stock provide stockholders
with separate securities which are intended to reflect the performance of the
General Division and Tissue Repair Division ("GTR"), respectively, and the
allocation of tax benefits between the divisions pursuant to the management and
accounting policies adopted by the Board of Directors (the "Board") of Genzyme
Corporation. The approval of the Genzyme Stock Proposal did not result in any
transfer of assets and liabilities of the Company or its subsidiaries. The
Company prepares separate financial statements for the General Division and GTR
in addition to consolidated financial information of the Company.

         Principles of Consolidation: The consolidated financial statements
include the accounts of the Company and its wholly-owned subsidiaries.
Investments in companies and joint ventures in which the Company has a
substantial ownership interest of approximately twenty-percent to fifty-percent,
or in which the Company participates in policy decisions are accounted for using
the equity method. Accordingly, the Company's share of the earnings of these
entities is included in combined net income. Investments of less than 20% are
reported at fair value (see "Investments"). All significant intercompany items
and transactions have been eliminated in consolidation. Certain items in the
consolidated financial statements for the periods prior to December 31, 1994
have been reclassified to conform with the current year's presentation.

         Use of Estimates: The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
certain estimates and assumptions that effect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reported period. Actual results could differ from those estimates.

         Cash and Cash Equivalents: Cash equivalents, consisting principally of
money market funds and municipal notes purchased with initial maturities of
three months or less, are valued at cost plus accrued interest, which
approximates market.

         Investments: Short-term investments include all investments with
remaining maturities of twelve months or less. Long-term investments include all
investments with remaining maturities greater than twelve months. The Company
classifies its equity investments as available-for-sale and its investments in
debt securities as either held-to-maturity or available-for-sale based on facts
and circumstances present at the time the investments are purchased. Equity
investments are included in "Other noncurrent assets" on the consolidated
balance sheet (See Note D Investments). As of December 31, 1995, the Company
classified all investments in debt

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



securities as available-for-sale.

         These investments are reported at fair value as of the balance sheet
date with unrealized holding gains and losses (the adjustment to fair value)
included as a separate component of Stockholder's equity. If the adjustment to
fair value reflects a decline in the value of the investment, management
considers all available evidence to evaluate the extent to which the decline is
"other than temporary" based on factors including (but not limited to) (i) the
length of time and extent to which the market value has been less than cost;
(ii) the financial condition and near-term prospects of the issuer, including
any specific events which may influence the operations of the issuer; and (iii)
the intent and ability of the Company to retain its investment in the issuer for
a period of time sufficient to allow for any anticipated recovery in market
value.

         Fair Value of Financial Instruments: The fair value of investments is
obtained from market quotations and is disclosed in Note D. The fair value of
the Company's subordinated debentures is obtained from a market maker in the
debentures and is disclosed in Note H. The fair value of foreign currency
forward contracts is based on forward rates in effect at December 31, 1995 and
is disclosed below (see -- Hedging).

         Inventories: Inventories are valued at the lower of cost (first-in,
first-out method) or market.

         Property, Plant and Equipment: Property, plant and equipment are stated
at cost. Provision for depreciation is computed using the straight-line method
over the estimated useful lives of the assets (three to ten years for plant and
equipment, five to seven years for furniture and fixtures, and twenty to forty
years for buildings). Certain specialized manufacturing equipment (with a net
book value of $34.1 million at December 31, 1995) is depreciated over its
remaining useful life using the units-of-production method. The remaining life
and recoverability of such equipment is evaluated periodically based on the
appropriate facts and circumstances. Leasehold improvements are amortized over
the lesser of the useful life or the term of the respective lease. For products
expected to be commercialized, the Company capitalizes, to construction
in-progress, the costs of manufacturing process validation and optimization
incurred beginning when the product is deemed to have demonstrated technological
feasibility and ending when the asset is substantially complete and is ready for
its intended use. Qualified costs include direct labor and material, and
incremental fixed overhead to the extent incurred. These costs are depreciated
using the units of production method.

         Issuance of Stock by a Subsidiary: Gains on the issuance of stock by a
subsidiary are included in net income unless the subsidiary is a research and
development, start-up or development stage company or an entity whose viability
as a going concern is under consideration. In those situations the Company
accounts for the change in its proportionate share of subsidiary equity
resulting from the additional equity raised by the subsidiary as an equity
transaction.

         Intangibles: Intangible assets consist primarily of goodwill which is
amortized on a straight-line basis over seven to eleven years. The remaining
intangibles, including customer lists, patents and a covenant not to compete are
being amortized on a straight-line basis over five to eleven years. Management's
policy regarding intangible assets is to evaluate the recoverability of its
intangible assets when the facts and circumstances suggest that these assets may
be impaired. This analysis relies on a number of factors, including operating



                                     -12-

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


results, business plans, budgets, economic projections and changes in
management's strategic direction or market emphasis. The test of such
recoverability is a comparison of the asset to expected cumulative
(undiscounted) operating income of the acquired entity over the remaining life
of the asset. If the book value of the intangible asset exceeds undiscounted
cumulative operating income, the write-down is computed as the excess of the
asset over the present value of operating income discounted at the Company's
weighted average cost of capital over the remaining amortization period. (See
Note K - Goodwill Impairment and Restructuring Costs)

         Revenue Recognition: Revenues from product sales are recognized when
goods are shipped and are net of third party contractual allowances, as
applicable. Revenues from service sales are recognized when the service
procedures have been completed. Revenues from research and development contracts
are recognized over applicable contractual periods as specified by each
contract.

         Translation of Foreign Currencies: The financial statements of the
Company's foreign subsidiaries are translated from local currency into U.S.
dollars using the current exchange rate at the balance sheet date for assets and
liabilities and the average exchange rate prevailing during the period for
revenues and expenses. The local currency for all Company foreign subsidiaries
is considered to be the functional currency for each entity and accordingly,
translation adjustments for these subsidiaries are reported as a separate
component of Stockholder equity. Exchange gains and losses on intercompany
balances of a long-term investment nature are also recorded as a charge or
credit to Stockholder equity. Transaction gains and losses are recorded in
income and totaled $(840,000), $(41,000), and $(322,000) for the years ended
December 31, 1995, 1994 and 1993, respectively.

         Hedging: The Company enters into forward contracts to reduce foreign
currency exchange risk. Such contracts are revalued using current exchange rates
at the balance sheet date. Gains and losses on forward contracts intended to
hedge identifiable foreign currency commitments are deferred and included in the
measurement of the related foreign currency transaction. All other gains and
losses on revaluation of forward contracts are included in net income. At
December 31, 1995, the Company had forward exchange contracts valued at
$1,209,000. Related gains and losses were not material to the financial
statements.

         Research and Development: Research and development costs are expensed
in the period incurred. Costs of purchased technology which management believes
has not demonstrated technological feasibility and for which there is no
alternative future use are charged to expense in the period of purchase.

         Income Taxes: The Company uses the asset and liability method of
accounting for deferred income taxes. The provision for income taxes includes
income taxes currently payable and those deferred because of temporary
differences between the financial statement and tax bases of assets and
liabilities. The Company has not provided for possible U.S. taxes on the
undistributed earnings of foreign subsidiaries that are considered to be
reinvested indefinitely. At December 31, 1995, such undistributed foreign
earnings were approximately $1,731,000.

         Net Income (Loss) Per Share: The method of calculating income per share
for General Division Stock and TR Stock reflects the terms of the Articles of
Organization, as amended, which provide that dividends may be declared and paid
only out of the lesser of funds of Genzyme legally available therefore and each
division's Available Dividend Amount, as defined. The Company computes income

per share by dividing the income attributable to each class of stock by the
weighted average number of shares of that stock and dilutive common stock
equivalents and other potentially dilutive securities outstanding during the
applicable period. Income attributable to General Division Stock and TR Stock
equals the respective division's net income or loss for the relevant period
determined in accordance with generally accepted accounting principles in effect
at such time, adjusted by the amount of tax benefits allocated to or from either
division pursuant to the accounting policies adopted by the Board of Directors
(the "Board"). The accounting policies provide that, as of the end of any fiscal
quarter of Genzyme, any projected annual tax benefit attributable to any
division that cannot be utilized by such division to offset or reduce its
current or deferred income tax expense may be allocated to the other division
without any compensating payment or allocation. Further description of
management and accounting policies are included in the notes to the General
Division financial statements.

         Income per share assuming full dilution is determined by dividing net
income plus subordinated debenture interest (net of capitalized amounts) by the
weighted average number of common shares outstanding during the year after
giving effect for common stock equivalents arising from stock options and
warrants and for subordinated debentures assumed converted to common stock.

         Net income (loss) attributable to General Division and TR Stock and net
income (loss) per share gives effect to the provisions of the Genzyme Stock
Proposal and, accordingly, periods prior to December 15, 1994 are presented on a
pro forma basis.

         Accounting for Stock-Based Compensation: Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS
123"), will require the Company to either elect expense recognition under SFAS
123 or its disclosure-only alternative for stock-based employee compensation.
The expense recognition provision encouraged by SFAS 123 would require fair
value-based financial accounting to recognize compensation expense for employee
stock compensation plans. SFAS 123 must be adopted in the Company's fiscal 1996
financial statements with comparable disclosures for the prior year. The Company
has determined that it will elect the disclosure-only alternative permitted
under SFAS 123. The Company will be required to disclose pro forma net income
and pro forma earnings per share in the footnotes using the fair value based
method beginning in fiscal 1996 with comparable disclosures for fiscal 1995. The
Company has not determined the impact of these pro forma adjustments to its net
income or earnings per share.

         Financial Instruments: Financial instruments that potentially subject
the Company to significant concentrations of credit risk consist principally of
cash and cash equivalents, current and non-current investments. The Company
generally invests its cash investments in investments-grade securities.

         Uncertainties: The Company is subject to risks common to companies in
the Biotechnology industry, including but not limited to, development by the
Company or its competitors of new technological innovations, dependence on key
personnel, protection of proprietary technology, and compliance with FDA
government regulations.

NOTE B  ACQUISITIONS

         In April 1993, the Company acquired Virotech System-Diagnostika, GmbH
in Germany, for approximately $10,200,000, of which approximately $8,100,000 was
recorded as goodwill. In May 1993 Genzyme srl, a wholly-owned subsidiary of the

Company located in Italy, acquired certain assets of Omnia Res srl for
approximately $700,000, of which approximately $100,000 was recorded as
goodwill. These acquisitions were accounted for as purchases. Accordingly, the
associated net assets and operations have been included in the Company's
financial statements since the acquisition dates. Pro forma information is not
presented since the impact of the acquisition on financial statement periods
prior to the acquisition is not material.

         In July 1994, the Company paid approximately $6,100,000 for
newly-issued shares of common stock representing 51% of the outstanding common
stock of Sygena A.G. ("Sygena"), a Swiss manufacturer of high performance
chemicals used in the development of pharmaceuticals. Based on certain put and
call options in the Acquisition Agreement, which effectively ensure the purchase
by the Company of the remaining outstanding shares during the period from July
1, 1996 through June 30, 1999, the Company accounted for the acquisition as a
purchase of all of the outstanding shares of Sygena, and recorded a deferred
liability at a present value of approximately 9,000,000 Swiss francs for the
purchase of the remaining shares. The excess purchase price over the net assets
acquired was approximately 5,000,000 Swiss francs (approximately $4,000,000) and
was recorded as goodwill. The net assets and operations of Sygena have been
included in the Company's financial statements from the date of acquisition. Pro
forma information is not presented since the impact of the acquisition on
financial statement periods prior to the acquisition is not material.

         On December 15, 1994, Genzyme acquired BioSurface Technology, Inc.
("BioSurface") by issuing .575 of one share of TR Stock for each share of
BioSurface common stock. In the aggregate, 5,000,000 shares of TR Stock, valued
at $25,312,500, were issued representing 50% of the initial equity interest in
GTR. The acquisition was accounted for as a purchase. Accordingly, the
associated net assets and operations of BioSurface have been included in the
Company's financial statements since the date of acquisition. The excess of the
purchase price over the fair market value of the net assets acquired,
$11,215,000, was allocated to in-process research and development and charged to
operations.

         The following summary, prepared on a pro forma basis, presents the
consolidated results of operations as if BioSurface had been acquired at the
beginning of the periods presented. This pro forma summary does not necessarily
reflect the results of operations as they would have been if Genzyme and
BioSurface constituted a single entity during the periods presented and is not
necessarily indicative of results which may be obtained in the future.

         In October 1995, Genzyme acquired the publicly-held minority interest
in its majority-owned subsidiary, IG Laboratories, Inc. ("IG"), by issuing
approximately .125 of one share of General Division Stock for each share of IG
common stock. In the aggregate, approximately 385,255 shares of General Division
Stock, valued at approximately $22.5 million were issued. The acquisition was
accounted for as a purchase. The excess of the purchase price

over the fair market value of the net assets acquired, approximately $18.6
million, was allocated $14.2 million to in-process research and development and
charged to operations, and $4.4 million to goodwill to be amortized over 11
years. Pro forma information is not presented since the impact of the
acquisition on financial statement periods prior to the acquisition is not
material.

         In February 1996, Genzyme signed a definitive agreement to acquire
Genetrix Inc., a privately held genetic testing laboratory based in Phoenix,
Arizona, in a tax-free exchange of General Division Stock valued at
approximately $36.8 million. Genetrix Inc. will be merged with Genzyme's
Integrated Genetics diagnostic services business. The transaction will be
accounted for as a pooling of interests.

         In August 1993, the Company acquired 502,512 shares of the Series E
Convertible Preferred Stock (the "Series E Stock") of Univax Biologics, Inc.,
for $5.0 million in connection with an agreement to develop and commercialize
certain products. Upon the achievement of specified clinical milestones, the
Company is committed to making future milestone payments. In November 1995,
Univax merged with North American Biologicals, Inc.("NABI") and in connection
with the merger the General Division received 526,315 shares of NABI common
stock in exchange for the Series E Stock. The investment is classified as
available-for-sale and is included in "Other noncurrent assets" in the
consolidated balance sheets at fair market value. At December 31, 1995, this
value was approximately $5.7 million compared to a value of $2.7 million at
December 31, 1994.

         In September 1993, the Company acquired 714,286 shares of common stock
of Argus Pharmaceuticals, Inc. ("Argus") for $5.0 million in connection with an
agreement to develop and commercialize certain products. Upon the achievement of
certain specified clinical milestones, the Company is committed to making future
milestone payments and an additional $5.0 million investment in Argus. In August
1994, pursuant to the Common Stock Purchase Agreement, Argus delivered to the
Company an additional 132,325 shares resulting in a total of 846,611 shares held
by the Company. The investment is classified as available-for-sale and is
included in "Other noncurrent assets" in the consolidated balance sheets at fair
market value. At December 31, 1994, this value was approximately $1.8 million.
The Company believed that a portion of the impairment in the value of the
investment in Argus was "other than temporary" and accordingly, a loss of
approximately $3.3 million was charged to operations in 1994. In September 1995,
Argus combined with Triplex Pharmaceuticals and Oncologix to form Aronex. In
connection with this merger, the common stock of Argus was redesignated as
common stock of Aronex. At December 31, 1995 the value of this investment was
$3.7 million.

         Pursuant to the Common Stock Purchase Agreement (the "Agreement") dated
as of June 24, 1994 between the Company and Celtrix Pharmaceuticals, Inc.
("Celtrix"), the Company acquired 1,550,388 restricted shares, approximately
11.5% of the common stock of Celtrix outstanding after the acquisition, for
$10.0 million. In November 1994, Celtrix announced a delay in the
commercialization of an application of a key product and in February 1995,
Celtrix announced that it had halted all studies related to another of its key
development products. These announcements resulted in a decline in the fair
market value of the Company's investment. The Company believed that a portion of
the impairment in the value of the investment in Celtrix was "other than
temporary". Accordingly, a loss of approximately $6.1 million was charged to
operations in 1994. In 1995, Celtrix exercised its option to require the Company
to purchase additional shares of Celtrix at fair market value. As a result in
December 1995, the Company acquired an additional 1,472,829 shares at $3 per
share. The investment is classified as available-for-sale and is included in
"Other noncurrent assets". At December 31, 1995, this value was approximately
$7.7 million.

         Net realized losses included in investment income for 1995 were
$110,000 Net realized gains included in investment income for 1994 and 1993 were
$1,430,000 and $1,647,000, respectively. Gross unrealized holding gains of
$2,073,000 and unrealized holding losses of $10,000, were recorded at December
31, 1995 in Stockholders' equity as compared to unrealized holding losses of
$5,704,000 recorded at December 31, 1994.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


         In July 1993, GTC, a wholly-owned subsidiary of the Company
specializing in transgenic technology which was incorporated in February 1993,
completed an initial public offering of 1,500,000 shares of its common stock
priced at $8.00 per share. The offering resulted in an increase in the value of
the Company's investment in GTC of $7.6 million which was recorded as an
increase to additional paid-in capital. At December 31, 1993, the Company owned
4,000,000 shares or approximately 73% of the outstanding common stock of GTC.

         On October 1, 1994, GTC acquired TSI Corporation ("TSI") in a merger
transaction in which GTC issued two-tenths (0.2) of one share of GTC common
stock for each share of TSI common stock, in a transaction accounted for as a
purchase. As a result of the acquisition, the Company's percentage ownership of
GTC common stock declined from approximately 73% to approximately 40%.
Accordingly, the Company began accounting for its investment in GTC under the
equity method.

         In February 1995, GTC exercised its option to sell to the Company
500,000 additional shares of GTC common stock at a price of $8.00 per share. The
$4.0 million acquisition cost has been added to the Company's equity investment
in this subsidiary. In June 1995, the Company converted approximately $4.0
million of GTC debt into equity through the acquisition of 1.3 million shares of
GTC common stock. In July 1995, GTC acquired Biodevelopment Laboratories, Inc.

NOTE I  STOCKHOLDERS' EQUITY

         Immediately prior to the Effective Date, as defined in Note A,
approximately 15,791,000 shares of Genzyme common stock were reserved for
issuance under the Company's 1990 Equity Incentive Plan, 1988 Director Stock
Option Plan, 1990 Employee Stock Purchase Plan, outstanding warrants (the
"Warrants"), and the conversion of the 6 3/4% Convertible Subordinated Notes Due
2001 (the "Notes").

         Pursuant to antidilution provisions in the agreements covering the
options, Genzyme has adjusted each option outstanding on the Effective Date to
provide for separation of the option into an option exercisable for General
Division Stock and an option exercisable for the number of shares of TR Stock
that the holder would have received if the holder had exercised the option
immediately prior to the Effective Date.

         The Warrants provide that the holder of the Warrant is entitled to
receive the number of shares of General Division Stock and TR Stock upon
exercise of the Warrant that the holder would have received if the holder had
exercised the Warrant immediately prior to the Effective Date.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


         Pursuant to the indenture under which the Notes were issued, the
conversion privilege of the Notes was adjusted so that the holder of a Note
converted after the Effective Date will receive, in addition to the shares of
General Division Stock into which the Note is convertible, the same number of
shares of TR Stock as the holder would have received had the holder converted
the Note immediately prior to the Effective Date.

         In September 1995, Genzyme sold 3,000,000 shares of Tissue Repair
Common Stock to the public at a price of $15 per share for net proceeds of $42.4
million after underwriting discounts and commissions. In October 1995, Genzyme
sold 2,875,000 shares of General Division Common Stock to the public for $51.25
per share for net proceeds of $141.5 million.

         At December 31, 1995, approximately 11,185,804 shares of General
Division Stock and 3,478,585 shares of TR Stock were reserved for issuance under
the 1990 Equity Incentive Plan as amended, the 1988 Director Stock Option Plan
as amended, the 1990 Employee Stock Purchase Plan as amended outstanding
warrants, and the conversion of the Notes.

         Preferred Stock. Shares of Preferred Stock may be issued from time to
time in one or more series. The Board of Directors may determine, in whole or in
part, the preferences, voting powers, qualifications and special or relative
rights or privileges of any such series before the issuance of any shares of
that series. The Board of Directors shall determine the number of shares
constituting each series of Preferred Stock and each series shall have a
distinguishing designation.

         Stock Options. Pursuant to the Company's 1990 Equity Incentive Plan as
amended (the "Plan"), options may be granted to purchase an aggregate of
7,600,000 shares of General Division Stock and 2,000,000 shares of TR Stock. The
Plan allows the granting of incentive stock options and nonstatutory stock
options at not less than fair market value at date of grant, and stock
appreciation rights, performance shares, restricted stock and stock units to
employees and consultants of the Company, each with a maximum term of ten years.
In addition, the Company has a 1988 Director Stock Option Plan, as amended,
pursuant to which nonstatutory stock options up to a maximum of 100,000 shares
and 70,000 shares, respectively, of General Division Stock and TR Stock, at a
rate of 1,600 shares and 400 shares, respectively, for each year of service are
automatically granted at fair market value to members of the Board of Directors
of the Company upon their election or reelection as Directors. All options
expire ten years after the initial grant date and vest over various periods.

         Stock Rights. In 1989, the Company's Board issued a dividend of one
preferred stock purchase right (a "Common Stock Right") on each share of Common
Stock. At the Effective Date, the Rights Agreement under which the rights were
issued was amended and restated to reflect the change in the capital structure
of the Company and the Board declared a distribution to holders of TR Stock of a
right (a "TR Stock Right") on each outstanding share of TR Stock. The Restated
Rights Agreement provides that each General Division Stock Right, which replaced
the Common Stock Right, and each TR Stock Right, when it becomes exercisable,
will entitle the holder to purchase from the Company (i) in the case of a
General Division Stock Right, one one-hundredth of a share of Series A Junior
Participating Preferred Stock at a price of $52, subject to adjustment, and (ii)
in the case of a TR Stock Right, one one-hundredth of a share of Series B Junior
Participating Preferred Stock at a price of $25, subject to adjustment.
The rights expire on March 28, 1999.

         Stock Warrants. The Company has issued warrants which, when exercised,
grant the holders one share of General Division Stock and .135 shares of TR
Stock. These warrants were granted in exchange for the receipt of options to
purchase the partnership interests of Genzyme Development Partners, L.P. (the
"Surgical Aids Partnership") the callable common stock of Neozyme II Corporation
("Neozyme II"), and in connection with Genzyme's purchase of the publicly-held
shares of IG Laboratories, Inc.("IG") in exchange for IG warrants. All proceeds
from the exercise of these warrants will be allocated to the General Division
(see "TR Designated Shares"). The outstanding warrants were issued under the
following terms:

automatically terminate upon Genzyme's exercise of its option to purchase all of
the callable common stock of Neozyme II. These warrants have an exercise price

Neozyme I and II

         In 1992, the Company entered into a development contract with Neozyme
II whereby the Company was engaged to perform all research, development and
clinical testing activities related to products and programs for which Neozyme
II was licensed. The Company received $5,000,000 in 1992 under the technology
license agreement pursuant to which the Company granted Neozyme II exclusive
rights to manufacture and sell the products developed under the technology
license agreements.

         The funds for Neozyme II's development contract were raised by the sale
of 2,415,000 units for net proceeds of $78,038,000. Each unit consisted of one
share of Neozyme II callable common stock, one Series N warrant and one callable
warrant to purchase one share of General Division Stock and .135 shares of TR
Stock. Included in accounts receivable as of December 31, 1995 and 1994 was
$2,469,000 and $729,000, respectively, due from Neozyme II.

         The Company has an option to purchase all of the shares of the Neozyme
II callable common stock for cash, shares of General Division Stock or any
combination thereof (determined at Genzyme's sole discretion) at $117.00 per
share from January 1, 1996 through December 31, 1996, subject to downward
adjustment if exercised before December 31. Due to the uncertainties inherent in
the very early stages of the research into CFTR, management did not consider the
exercise of the option probable and, accordingly, charged to operations in 1992
the $16,905,000 appraised fair value of this purchase option.

         In December 1993, the Company exercised its option to purchase one of
the two remaining research programs being funded by Neozyme I, created in 1990
for a purchase price of $24,000,000 in cash. As part of the purchase, the
Company retained $0.6 million to fund the costs of the Neozyme I dissolution
which occurred in 1994, and any future tax liabilities. This transaction was
accounted for as a purchase of in-process research and development and its value
charged to operations in 1993.

The Surgical Aids Partnership

         In September 1989, the Company entered into a development contract
valued at approximately $37,000,000 with the Surgical Aids Partnership ("the
Partnership") to perform research and development of products based on
hyaluronic acid for use as surgical aids to reduce the incidence and severity of
postoperative adhesions. The Company received a technology license fee of
$1,500,000 in November 1989 and was reimbursed its development costs plus 10%
through the first quarter of 1994 when the Partnership's funds were exhausted.
The General Partner believes that additional funds will be required to complete
the development, clinical testing and commercialization of the Partnership's
products. Although the Company is not obligated to provide additional funding,
the Purchase Option (see below) terminates unless the Company commits on an
annual basis to provide funding for continuation of the research and development
programs for the next twelve month period or until receipt of FDA approval of
one of the Partnership's products is obtained, whichever is shortest. The
Company spent approximately $6.4 million and $6.5 million on the Partnership's
development programs in 1995 and 1994, respectively and has committed to fund
the programs in 1996, expecting to spend approximately $7.9 million (unaudited).
Included in accounts receivable as of December 31, 1994 was $199,000 due from
the Partnership.

         The Company also entered into a joint venture agreement with the
Partnership to manufacture and market the Partnership's products, to share in
the profits, to make non-interest bearing loans for working capital
deficiencies, and to make capital contributions as deemed necessary by the
Partnership in connection with the business of the joint venture. The exact
amounts and timing of these expenditures and contributions cannot be determined
at this time.

         The Company also obtained an option (the "Purchase Option") to purchase
all of the outstanding partnership interests for a payment of approximately
$26,000,000 in cash, General Division Stock or a combination thereof determined
at Genzyme's sole discretion, plus future royalty payments. The Purchase Option
does not become exercisable until at least twenty-four months after the first
commercial sale of a product of the Partnership.

         Deferred revenue from related parties at December 31 includes the
following:

NOTE K  GOODWILL IMPAIRMENT AND RESTRUCTURING COSTS

         In the fourth quarter of 1993, the Company recognized an expense of
$23.7 million to reduce the carrying value of intangibles to the realizable
value based on revised estimates of continuing value and future benefits. The
majority of the write-off, $21.9 million, related to the goodwill recorded in

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


connection with the acquisition of Genetic Design Inc. ("GDI") in June 1992. The
goodwill write-off was based on an analysis of GDI's business conducted in the
fourth quarter of 1993, including the loss of significant state public paternity
testing contracts, which indicated that the environment for public paternity
testing, GDI's primary business market, had changed significantly since the
acquisition, and therefore called into question the carrying value of the
acquisition-related GDI goodwill. The business review disclosed the development
of a competitive environment which emphasized cost rather than service and
performance, intense price competition from a major competitor, a general
reduction in the ordering of identity tests due to governmental budgetary
restrictions and uncertainties as to the level of federal funding of state
testing activities, a cost structure at GDI which made it difficult for GDI to
continue as an effective competitor in a slow-growth, cost-driven environment
and the decreased likelihood of sufficient support in Congress for passage of
additional social legislation which would significantly increase federal funding
of state testing activities. These changed circumstances resulted in a
determination to reduce the carrying value of GDI goodwill to zero at the end of
1993. The remaining $1.8 million of write-offs consisted of approximately $1.1
million of patent rights resulting from the purchase of Enzymatix Ltd. by
Genzyme Ltd. (UK) and approximately $0.7 million of intangible assets resulting
from the acquisition of a clinical testing laboratory by IG. Also in the fourth
quarter of 1993, the Company incurred restructuring charges of $2.8 million
related to the consolidation of laboratory operations in its Diagnostic Services
business. The expenses were related to severance of $1.2 million for an
estimated 45 employees; lease costs of $0.8 million; equipment movement and
disposal of $0.2 million; costs incurred to restructure the Company's paternity
product line of $0.2 million and other costs of $0.4 million. All costs were
cash expenditures in 1994. The restructuring plan was undertaken to consolidate
lab testing services into the Company's most cost-effective testing locations,
transfer virtually all accounting functions to the Company's headquarters and
streamline the paternity product line at GDI.

NOTE L  COMMITMENTS AND CONTINGENCIES

         In December 1994, the Company fully settled litigation brought by
Granada BioSciences, Inc., Houston, Texas, by payment of $1,980,000 in cash. The
dispute arose out of a contract between Granada R&D Ventures, a predecessor of
Granada BioSciences, and Integrated Genetics, prior to its merger with the
Company in 1989, regarding development of recombinant fertility hormones for
cows and other animals.

         From time to time the Company has been subject to legal proceedings and
claims arising in connection with its business. At December 31, 1995, there were
no asserted claims against the Company which, in the opinion of management, if
adversely decided would have a material adverse effect on the Company's
financial position and results of operations.

</TABLE>

         At December 31, 1995 and 1994, valuation allowances of $20.6 million
and $32.2 million, respectively, were recorded to offset a portion of the
deferred tax assets related to the realization of net operating loss
carryforwards, and deductions relating to the purchase of in-process research
and development and the future disposition of certain stock purchase options.
Realization of the net deferred tax asset is dependent on generating sufficient
taxable income prior to the expiration of loss carryforwards. Although
realization is not assured, management believes that it is more likely than not
that all of the net deferred tax assets will be realized. The amount of the
deferred tax asset considered realizable, however, could be reduced in the near
term if estimates of future taxable income during the carryforward period are
reduced.

         A total of $1.5 million of the valuation allowance relates to tax
assets arising from the IG Labs acquisition. If any portion of this tax asset is
ultimately realized, the remaining goodwill related to the IG Labs acquisition
will be reduced accordingly.

         At December 31, 1995, the Company had U.S. net operating loss
carryforwards of $26.4 million for income tax purposes. These carryforwards
expire from 2000 to 2010. Utilization of tax net operating loss carryforwards
may be limited under section 382 of the Internal Revenue Code of 1986.

         At December 31, 1995, the Company also had U.K. operating loss
carry-forwards for income tax purposes of approximately $2.9 million which are
available indefinitely to offset future taxable income in the U.K.

NOTE N  BENEFIT PLANS

         The Company has defined-benefit pension plans covering substantially
all the employees of its foreign subsidiaries. Pension expense for 1995, 1994
and 1993 was $498,000, $266,000 and $206,000, respectively. Pension costs are
funded as accrued. Actuarial and other disclosures regarding the plans are not

NOTE Q  SUBSEQUENT EVENTS

         In January 1996, Genzyme made a conditional offer to acquire
substantially all the assets of the Partnership for General Division Stock
valued at $93.0 million.

         In January 1996, GTR acquired certain real estate in Framingham,
Massachusetts for $6.8 million in cash, of which $5.7 million was allocated to
buildings and $1.1 million was allocated to land based on appraised values.

         In January 1996, GTC obtained a short-term loan in the amount of
$950,000 from Genzyme. The loan is due on March 31, 1996 and accrues interest at
a rate of 6 1/2% per annum.

         In February 1996, the Company announced a planned redemption of its 
6 3/4% Convertible Subordinated Notes. All holders elected to convert their
notes into shares of General Division Stock and TR Stock. Holders of the notes 
received 18.913 shares of General Division Stock and 2.553 shares of TR Stock 
in conversion of each $1,000 note.  Supplementary earnings per share for the
General Division which gives effect to the conversion of the notes as if such
conversion took place at the beginning of each period presented, is equal to
fully diluted earnings per share.

         In March 1996, an advisory panel to the U.S. Food and Drug
Administration ("the FDA") recommended that Genzyme be granted approval to
market one of the HA Products, Seprafilm(TM) bioresorbable membrane. The panel's
recommendation will be considered by the FDA in its final review of Genzyme's
premarket approval application.

         In March 1996, GTC entered into a Convertible Debt and Development
Funding Agreement with Genzyme under which Genzyme agreed to provide a revolving
line of credit in the amount of $10 million and has agreed to fund development
costs of the Antithrombin III ("AT-III") program through March 31, 1997. Under
the Agreement, GTC granted to Genzyme co-marketing rights to AT-III in all
territories other than Asia subject to negotiation and execution of a
development and supply agreement between the parties prior to 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 day period ending two days before
the Conversion at GTC's option 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 by Genzyme
at any time for up to the full amount outstanding.

         In March 1996, the GTR utilized $8.0 million of the Company's $15.0
million available credit line with Fleet Bank.

         In March 1996, the Board voted, subject in each case to the approval of
the stockholders, to adopt two amendments to the Company's 1990 Equity
Incentive Plan (the "Equity Plan"). These amendments would increase the
aggregate number of shares of General Division Stock that may be subject to
grants under the Equity Plan from 7,600,000 to 9,900,000 and the aggregate
number of shares of TR Stock that may be subject to grants under the Equity
Plan from 2,000,000 to 3,300,000 subject to adjustment for stock splits, stock
dividends and certain transactions affecting the Company's capital stock.

GENZYME GENERAL DIVISION


         REPORT OF INDEPENDENT ACCOUNTANTS

         To the Board of Directors and Stockholders of GENZYME CORPORATION:

                  We have audited the accompanying combined balance sheets of 
         the Genzyme General Division (as described in Note A) as of December 
         31, 1995 and 1994 and the related combined statements of operations 
         and cash flows and the combined financial statement schedule for each 
         of the three years in the period ended December 31, 1995. The combined 
         financial statements and financial statement schedule are the 
         responsibility of Genzyme Corporation's management. Our 
         responsibility is to express an opinion on these combined financial 
         statements and financial statement schedule based on our audits.

                  We conducted our audits in accordance with generally accepted
         auditing standards. Those standards require that we plan and perform
         the audit to obtain reasonable assurance about whether the financial
         statements are free of material misstatement. An audit includes
         examining, on a test basis, evidence supporting the amounts and
         disclosures in the financial statements. 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 combined financial statements of Genzyme
         General Division present fairly, in all material respects, the
         financial position of Genzyme General Division as of December 31, 1995
         and 1994 and the results of its operations and its cash flows for each
         of the three years in the period ended December 31, 1995, in conformity
         with generally accepted accounting principles. In addition, in our
         opinion, the combined financial statement schedule taken as a whole
         presents fairly, in all material respects, the information required to
         be included therein.

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

                            GENZYME GENERAL DIVISION
                     NOTES TO COMBINED FINANCIAL STATEMENTS


NOTE A  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Business: Genzyme General Division (the "General Division"), a division
of Genzyme Corporation (the "Company" or "Genzyme"), is a diversified human
health care business with product development, manufacturing and marketing
capabilities in therapeutic and diagnostic products, pharmaceuticals, and
diagnostic services.

         Basis of Presentation: The approval effective December 16, 1994 (the
"Effective Date") by the stockholders of Genzyme of the Genzyme Stock Proposal
as described in Genzyme's Prospectus/Proxy Statement dated November 10, 1994
resulted in the redesignation of Genzyme's common stock. The outstanding shares
of Genzyme common stock were redesignated as General Division Common Stock
("General Division Stock") on a share-for-share basis and a second class of
common stock, designated as Tissue Repair Division Common Stock ("TR Stock") was
distributed on the basis of .135 of one share of TR Stock for each share of
Genzyme's common stock held by stockholders of record on October 14, 1994.
General Division Stock and TR Stock provide stockholders with separate
securities which are intended to reflect the performance of the General Division
and Tissue Repair Division ("GTR"), respectively, and the allocation of tax
benefits between the divisions pursuant to the management and accounting
policies adopted by the Board of Directors (the "Board") of Genzyme Corporation.

         Dividends to the holders of General Division Stock will be limited to
the lesser of funds of Genzyme legally available for the payment of dividends
and the Available Tissue Repair Dividend Amount, as defined in Genzyme's
Articles of Organization, as amended. Although there is no requirement to do so,
the Board would declare and pay dividends on General Division Stock, if any,
based primarily on the earnings, financial condition, cash flow and business
requirements of the General Division. There is currently no intention of paying
dividends.

         Genzyme, subject to certain conditions, has the right to exchange each
outstanding share of TR Stock for any combination of cash and/or shares of
General Division Stock at a 30% premium over Fair Market Value. In addition,
following a disposition of all or substantially all assets of GTR, the shares of
TR Stock are subject to mandatory exchange by Genzyme for cash and/or shares of
General Division Stock at a 30% premium over Fair Market Value as determined by
the trading prices during a specified period prior to public announcement of the
disposition. Shares of General Division Stock are not subject to either optional
or mandatory exchange.

         On all matters as to which common stockholders generally are entitled
to vote, holders of General Division Stock are entitled to one vote per share
and holders of TR Stock are entitled to .29 votes per share from the Effective
Date through December 31, 1996. On January 1, 1997 and on each January 1 every
two years thereafter, the number of votes to which the holder of each share of
TR Stock shall be entitled shall be adjusted and fixed for two-periods to equal
the quotient (expressed as a decimal rounded to the nearest two decimal places)
obtained by dividing the fair market value of one share of TR Stock by the fair
market value of one share of General Division Stock as of such date. If no
shares of General Division Stock are outstanding on such date, or if shares of
TR Stock are entitled to vote separately as a class, each share of TR Stock
shall have one vote. Holders of each class vote together as a single class.
Except in limited circumstances provided under Massachusetts law and in
Genzyme's Articles of Organization, as amended, and in the management and
accounting policies adopted by the Board, holders of each class of common stock
will have no rights to vote on matters as a separate class. Separate meetings

              NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

of the holders of each class of common stock will not be held. If, when a
stockholder vote is taken on any matter as to which a separate vote by either
class is not required and the holders of either class of common stock would have
more than the number of votes required to approve any such matter, the holders
of that class will control the outcome of the vote on that matter.

         The combined financial statements of the General Division include the
financial position and results of operations and cash flows of all businesses of
Genzyme except those of GTR. The General Division's financial statements are
prepared using amounts included in Genzyme's consolidated financial statements.
Corporate allocations reflected in these financial statements are determined
based upon methods which management believes to be reasonable (see Note B).

         Genzyme provides holders of General Division Stock separate financial
statements, management's discussion and analysis, descriptions of businesses and
other relevant information for the General Division in addition to consolidated
financial information of Genzyme. Notwithstanding the attribution of assets and
liabilities (including contingent liabilities) between the General Division and
GTR for the purposes of preparing their respective historical and future
financial statements, this attribution and the change in the capital structure
of Genzyme as a result of the approval of the Genzyme Stock Proposal does not
affect legal title to the assets or responsibility for the liabilities of
Genzyme or any of its subsidiaries. Holders of General Division Stock are
shareholders of Genzyme, which continue to be responsible for all of its
liabilities. 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. Accordingly, Genzyme's consolidated
financial statements should be read in connection with the General Division's
financial statements.

         Except as stated in the amended articles, the accounting policies
applicable to the preparation of the financial statements of the General
Division may be modified or rescinded at the sole discretion of the Board
without the approval of the shareholders, although there is no intention to do
so.

         Principles of Combination: The combined financial statements include
the accounts of the General Division and its wholly-owned subsidiaries.
Investments in companies and joint ventures in which the General Division has a
substantial ownership interest of approximately twenty-percent to fifty-percent,
or in which the General Division participates in policy decisions are accounted
for using the equity method. Accordingly, the General Division's share of the
earnings of these entities is included in combined net income. Investments of
less than 20% are reported at fair value. All significant intercompany items and
transactions have been eliminated in combination. Certain items in the combined
financial statements for the periods prior to December 31, 1994 have been
reclassified to conform with the current year's presentation.

         Use of Estimates: The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
certain estimates and assumptions that effect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reported period. Actual results could differ from those estimates.

         Cash and Cash Equivalents: Cash equivalents, consisting principally of
money market funds and municipal notes purchased with initial maturities of
three months or less, are valued at cost plus accrued interest, which
approximates market.


                                    -41-

                            GENZYME GENERAL DIVISION
               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)


         Investments: Short-term investments include all investments with
remaining maturities of twelve months or less. Long-term investments include
all investments with remaining maturities greater than twelve months. The
General Division classifies its equity investments as available-for-sale and
its investments in debt securities as either held-to-maturity or
available-for-sale based on facts and circumstances present at the time the
investments are purchased. Equity investments are included in "Other noncurrent
assets" on the combined balance sheet (See Note F - Investments). As of
December 31, 1995, the General Division classified all investments in debt
securities as available-for-sale.

         These investments are reported at fair value as of the balance sheet
date with unrealized holding gains and losses (the adjustment to fair value)
included in Division equity. If the adjustment to fair value reflects a decline
in the value of the investment, management considers all available evidence to
evaluate the extent to which the decline is "other than temporary" based on
factors including (but not limited to) (i) the length of time and extent to
which the market value has been less than cost; (ii) the financial condition and
near-term prospects of the issuer, including any specific events which may
influence the operations of the issuer; and (iii) the intent and ability of the
holder to retain its investment in the issuer for a period of time sufficient to
allow for any anticipated recovery in market value.

         Fair Value of Financial Instruments: The fair value of investments is
obtained from market quotations and is disclosed in Note F. The fair value of
the General Division's subordinated debentures is obtained from a market maker
in the debentures and is disclosed in Note J. The fair value of foreign currency
forward contracts is based on forward rates in effect at December 31, 1995 and
is disclosed below (see -- Hedging).

         Inventories: Inventories are valued at the lower of cost (first-in,
first-out method) or market.

         Property, Plant and Equipment: Property, plant and equipment are stated
at cost. Provision for depreciation is generally computed using the
straight-line method over the estimated useful lives of the assets (three to ten
years for plant and equipment, five to seven years for furniture and fixtures,
and twenty to forty years for buildings). Certain manufacturing equipment (with
a net book value of $34.1 million at December 31, 1995) is depreciated over its
remaining useful life using the units-of-production method. The remaining life
and recoverability of such equipment is evaluated periodically based on the
appropriate facts and circumstances. Leasehold improvements are amortized over
the lesser of the useful life or the term of the respective lease. For products
expected to be commercialized, the General Division capitalizes, to construction
in-progress, the costs of manufacturing process validation and optimization
incurred beginning when the product is deemed to have demonstrated technological
feasibility and ending when the asset is substantially complete and is ready for
its intended use. Qualified costs include direct labor and material, and
incremental fixed overhead to the extent incurred. These costs are depreciated
using the units of production method.

         Issuance of Stock by a Subsidiary: Gains on the issuance of stock by a
subsidiary are included in net income unless the subsidiary is a research and
development, start-up or development stage company or an entity whose viability
as a going concern is under consideration. In those situations the General
Division accounts for the change in its proportionate share of subsidiary equity
resulting from the additional equity raised by the subsidiary as an equity

transaction.

         Intangibles: Intangible assets consist primarily of goodwill which is
amortized on a straight-line basis over seven to eleven years. The remaining
intangibles, including customer lists, patents and a covenant not to compete are
being amortized on a straight-line basis over five to eleven years. Management's
policy is to evaluate the recoverability and useful lives of its intangible
assets when the facts and circumstances suggest that these assets may be
impaired or their useful lives may have changed. This analysis relies on a
number of factors, including operating results, business plans, budgets,
economic projections and changes in management's strategic direction or market
emphasis. The test of such recoverability is a comparison of the asset to
expected cumulative (undiscounted) operating income of the acquired entity over
the remaining life of the asset. If the book value of the intangible asset
exceeds undiscounted cumulative operating income, the write-down is computed as
the excess of the asset over the present value of operating income discounted at
the General Division's weighted average cost of capital over the remaining
amortization period. (See Note M - Goodwill Impairment and Restructuring Costs)

         Revenue Recognition: Revenues from product sales are recognized when
goods are shipped and are net of third party contractual allowances, as
applicable. Revenues from service sales are recognized when the service
procedures have been completed. Revenues from research and development contracts
are recognized over applicable contractual periods as specified by each
contract.

         Translation of Foreign Currencies: The financial statements of the
General Division's foreign subsidiaries are translated from local currency into
U.S. dollars using the current exchange rate at the balance sheet date for
assets and liabilities and the average exchange rate prevailing during the
period for revenues and expenses. The local currency for all General Division
foreign subsidiaries is considered to be the functional currency for each entity
and accordingly, translation adjustments for these subsidiaries are charged or
credited to Division equity. Exchange gains and losses on intercompany balances
of a long-term investment nature are also recorded as a charge or credit to
Division equity. Transaction gains and losses are recorded in income and totaled
$(840,000), $(41,000), and $(322,000) for the years ended December 31, 1995,
1994 and 1993, respectively.

         Hedging: The General Division enters into forward contracts to reduce
foreign currency exchange risk. Such contracts are revalued using current
exchange rates at the balance sheet date. Gains and losses on forward contracts
intended to hedge identifiable foreign currency commitments are deferred and
included in the measurement of the related foreign currency transaction. All
other gains and losses on revaluation of forward contracts are included in net
income. At December 31, 1995, the General Division had forward exchange
contracts valued at $1,209,000. Related gains and losses were not material to
the financial statements.

         Research and Development: Research and development costs are expensed
in the period incurred. Costs of purchased technology which management believes
has not demonstrated technological feasibility and for which there is no
alternative future use are charged to expense in the period of purchase.

         Income Taxes: The General Division uses the asset and liability method
of accounting for deferred income taxes. The provision for income taxes includes
income taxes currently payable and those deferred because of temporary
differences between the financial statement and tax bases of assets and
liabilities. The General Division has not provided for possible U.S. taxes on

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)


the undistributed earnings of foreign subsidiaries that are considered to be
reinvested indefinitely. At December 31, 1995, such undistributed foreign
earnings were approximately $1,731,000.

         Net Income Per Share: The method of calculating income per share for
General Division Stock reflects the terms of the Articles of Organization, as
amended, which provide that dividends may be declared and paid only out of the
lesser of funds of Genzyme legally available therefore and each division's
Available Dividend Amount, as defined. For the purpose of computing net income
per common share of General Division Stock for periods prior to December 12,
1994, the number of shares and share equivalents of General Division Stock prior
to the Effective Date are assumed to be the same as the total number of shares
and share equivalents of Genzyme common stock. The General Division computes
income per share by dividing the income attributable to General Division Stock
by the weighted average number of shares of General Division Stock and dilutive
common stock equivalents and other potentially dilutive securities outstanding
during the applicable period. Income attributable to General Division Stock
equals the General Division's net income or loss for the relevant period
determined in accordance with generally accepted accounting principles in effect
at such time, adjusted by the amount of tax benefits allocated to or from the
General Division pursuant to the accounting policies adopted by the Board. The
accounting policies provide that, as of the end of any fiscal quarter of
Genzyme, any projected annual tax benefit attributable to any division that
cannot be utilized by such division to offset or reduce its current or deferred
income tax expense may be allocated to the other division without any
compensating payment or allocation.

         Income per share assuming full dilution is determined by dividing net
income plus subordinated debenture interest (net of capitalized amounts) by the
weighted average number of common shares outstanding during the year after
giving effect for common stock equivalents arising from stock options and
warrants and for subordinated debentures assumed converted to common stock.

         Net income attributable to General Division Stock and net income per
share for the years ended December 31, 1994 and 1993, give effect to the
provisions of the accounting policies adopted by the Board in connection with
the creation of the General Division and, accordingly, are pro forma
presentations.

         Accounting for Stock-Based Compensation: Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation" (SFAS
123"), will require the Company to either elect expense recognition under SFAS
123 or its disclosure-only alternative for stock-based employee compensation.
The expense recognition provision encouraged by SFAS 123 would require fair
value-based financial accounting to recognize compensation expense for employee
stock compensation plans. SFAS 123 must be adopted in the Company's fiscal 1996
financial statements with comparable disclosures for the prior year. The Company
has determined that it will elect the disclosure-only alternative permitted
under SFAS 123. The Company will be required to disclose pro forma net income
and pro forma earnings per share in the footnotes using the fair value based
method beginning in fiscal 1996 with comparable disclosures for fiscal 1995. The
Company has not determined the impact of these pro forma adjustments to its net
income or earnings per share.

         Financial Instruments: Financial instruments that potentially subject
the Company to significant concentrations of credit risk consist principally of
cash and cash equivalents, current and non-current investments. The Company
generally invests its cash investments in investments-grade securities.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)


         Uncertainties: The Company is subject to risks common to companies in
the Biotechnology industry, including but not limited to, development by the
Company or its competitors of new technological innovations, dependence on key
personnel, protection of proprietary technology, and compliance with FDA
government regulations.

NOTE B  RELATED PARTY TRANSACTIONS

         The following policies may be modified or rescinded by action of the
Board, or the Board may adopt additional policies, without approval of the
shareholders of Genzyme, although the Board has no present intention to do so.
Genzyme allocated certain corporate general and administrative expenses,
research and development expense and income taxes in accordance with the
policies described below.

         Financial Matters: As a matter of policy, the Company manages the
financial activities of the General Division and GTR on a centralized basis.
These financial activities include the investment of surplus cash; the issuance,
repayment and repurchase of short-term and long-term debt and the issuance and
repurchase of common stock. In preparing these financial statements for each of
the three years in the period ended December 31, 1995, transactions primarily
related to investments, short-term and long-term debt (including convertible
debt), related net interest and other financial costs have been attributed to
the General Division based upon its cash flows for the periods presented after
giving consideration to the debt and equity structure of the Company. At
December 31, 1995, the Company attributed all of its short-term and long-term
debt to the General Division based upon the specific purpose for which the debt
was incurred and the cash flow requirements of the General Division. All of the
Company's interest costs have been allocated to the General Division (see Note
J). The Company believes this method of allocation to be equitable and a
reasonable estimate of such costs as if the General Division operated on a
stand-alone basis.

         To the extent borrowings are deemed to occur between the General
Division and GTR, intercompany accounts have been established bearing interest
at the rate in effect from time to time under the Company's unsecured credit
lines or, if no such credit lines exist, at the prime rate charged by The First
National Bank of Boston from time to time. To date no such borrowings have
occurred; however, at December 31, 1995 GTR owed the General Division $2.0
million for services rendered in the normal course of business.

                  Shared Services: Genzyme's corporate general and
administrative functions and certain sales and marketing efforts related to
foreign market penetration are performed by the General Division. General,
administrative, sales and marketing expenses have been allocated to GTR based
upon utilization of such services as if the General Division and GTR operated on
a stand-alone basis. Management believes that such allocation is a reasonable
estimate of such expenses. These allocations for the years ended December 31,
1995, 1994 and 1993 were $4,355,000, $833,000 and $701,000, respectively. In
addition, costs incurred by the General Division related to research and
development for GTR products are charged to GTR. These charges for the years
ended December 31, 1995, 1994 and 1993 were $4,730,000, $3,331,000 and
$2,805,000, respectively.

         Income Taxes: The General Division is included in the consolidated U.S.
federal income tax return filed by Genzyme. Genzyme allocates current and
deferred taxes to its divisions by determining the tax provision of each
division, in accordance with generally accepted accounting principles, as if it
were a separate taxpayer. Accordingly, the realizability of deferred tax assets



























                                    -45-

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)


is assessed at the Division level. The sum of the tax provisions calculated for
individual divisions of Genzyme may not equal the consolidated tax provision
under this approach. The treatment of the allocation of a division's projected
tax benefit for purposes of income per share computation is discussed in Note A.

         Inter-Division Asset Transfers. The Board may at any time and from time
to time reallocate any program, product or other asset from one Division to any
other Division. All such reallocations will be done at fair market value,
determined by the Board, taking into account, in the case of a program under
development, the commercial potential of the program, the phase of clinical
development of the program, the expenses associated with realizing any income
from the program, the likelihood and timing of any such realization and other
matters that the Board and its financial advisors deem relevant. The
consideration for such reallocation may be paid by one Division to another in
cash or, in lieu of cash or other consideration, the Board may elect to account
for a reallocation of assets from GTR to the General Division as an increase in
the General Designated Shares and a reallocation of assets from the General
Division to GTR as either an increase in the TR Designated Shares or a reduction
in the General Designated Shares, if any, except that a reallocation of assets
from GTR to the General Division may not be accounted for as an increase in
General Designated Shares without a class vote of the holders of TR Stock.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)


         Immediately prior to the Effective Date, as defined in Note A,
approximately 15,791,000 shares of Genzyme common stock were reserved for
issuance under the Company's 1990 Equity Incentive Plan, 1988 Director Stock
Option Plan, 1990 Employee Stock Purchase Plan, and upon the exercise of
outstanding warrants (the "Warrants"), and the conversion of the 6 3/4%
Convertible Subordinated Notes Due 2001 (the "Notes").

         Pursuant to antidilution provisions in the agreements covering the
options, Genzyme has adjusted each option outstanding on the Effective Date to
provide for separation of the option into an option exercisable for General
Division Stock and an option exercisable for the number of shares of TR Stock
that the holder would have received if the holder had exercised the option
immediately prior to the Effective Date.

         The Warrants provide that the holder of the Warrant is entitled to
receive the number of shares of General Division Stock and TR Stock upon
exercise of the Warrant that the holder would have received if the holder had
exercised the Warrant immediately prior to the Effective Date.

         Pursuant to the indenture under which the Notes were issued, the
conversion privilege of the Notes was adjusted so that the holder of a Note
converted after the Effective Date will receive, in addition to the shares of
General Division Stock into which the Note is convertible, the same number of
shares of TR Stock as the holder would have received had the holder converted
the Note immediately prior to the Effective Date.

         At December 31, 1995, approximately 11,185,804 shares of General
Division Stock were reserved for issuance under the 1990 Equity Incentive Plan
as amended, the 1988 Director Stock Option Plan as amended, the 1990 Employee
Stock Purchase Plan as amended, and upon the exercise of outstanding warrants,
and the conversion of the Notes.

         Preferred Stock. Shares of Preferred Stock may be issued from time to
time in one or more series. The Board of Directors may determine, in whole or in
part, the preferences, voting powers, qualifications and special or relative
rights or privileges of any such series before the issuance of any shares of
that series. The Board of Directors shall determine the number of shares
constituting each series of Preferred Stock and each series shall have a
distinguishing designation.

         Stock Options. Pursuant to the Company's 1990 Equity Incentive Plan as
amended (the "Plan"), options may be granted to purchase an aggregate of
7,600,000 shares of General Division Stock and 2,000,000 shares of TR Stock. The
Plan allows the granting of incentive stock options and nonstatutory stock
options at not less than fair market value at date of grant, and stock
appreciation rights, performance shares, restricted stock and stock units to
employees and consultants of the Company, each with a maximum term of ten years.
In addition, the Company has a 1988 Director Stock Option Plan, as amended,
pursuant to which nonstatutory stock options up to a maximum of 100,000 shares
and 70,000 shares, respectively, of General Division Stock and TR Stock, at a
rate of 1,600 shares and 400 shares, respectively, for each year of service are
automatically granted at fair market value to members of the Board of Directors
of the Company upon their election or reelection as Directors. All options
expire ten years after the initial grant date.

                  Stock option activity is summarized below:

                                                                   SHARES

85,929 shares were issued in 1995, 1994 and 1993, respectively.

         Stock Rights. In 1989, the Company's Board issued a dividend of one

of the Company and the Board declared a distribution to holders of TR Stock of a
right (a "TR Stock Right") on each outstanding share of TR Stock. The Restated
Rights Agreement provides that each General Division Stock Right, which replaced

General Division Stock Right, one one-hundredth of a share of Series A Junior
Participating Preferred Stock at a price of $52, subject to adjustment, and (ii)
in the case of a TR Stock Right, one one-hundredth of a share of Series B Junior
Participating Preferred Stock at a price of $25, subject to adjustment. The
rights expire on March 28, 1999.

         Stock Warrants. The Company has issued warrants which, when exercised,
grant the holders one share of General Division Stock and .135 shares of TR
Stock. These warrants were granted in exchange for the receipt of options to
purchase the partnership interests of Genzyme Development Partners, L.P. (the
"Surgical Aids Partnership") the callable common stock of Neozyme II Corporation
("Neozyme II"), and in connection with Genzyme's purchase of the publicly-held
shares of IG Laboratories, Inc.("IG") in exchange for IG warrants. All proceeds

         TR Designated Shares. Pursuant to Genzyme's Articles of Organization,
as amended, TR Designated Shares are authorized shares of TR Stock which are not
issued and outstanding, but which the Board may from time to time issue, sell or
otherwise distribute without allocating the proceeds or other benefits of such
issuance, sale or distribution to GTR. At the Effective Date, 5,000,000 TR
Designated Shares were established. As a result of the distribution of
approximately 3,300,000 shares of TR Stock to holders of General Division Stock,
the number of TR Designated Shares were reduced by a corresponding amount. The
remaining 1,700,000 TR Designated Shares were reserved for issuance upon the

         The number of TR Designated Shares will be decreased by the number of
shares of TR Stock issued by Genzyme, the proceeds of which are allocated to the
General Division; the number of shares of TR Stock issued as a dividend to
holders of General Division stock; and the number of shares of TR Stock issued
upon the conversion of convertible securities, including the Notes, attributed
to the General Division. In addition, the number of TR Designated Shares can be
increased as a result of certain inter-division transactions. The remaining TR
Designated Shares are reserved for issuance upon the exercise of the Notes, the
aforementioned warrants and the stock options which resulted from the conversion
of Genzyme options into TR Stock and General Division Stock options (See Note

NOTE D  ACQUISITIONS

         In April 1993, the General Division acquired Virotech
System-Diagnostika, GmbH in Germany, for approximately $10,200,000, of which
approximately $8,100,000 was recorded as goodwill. In May 1993 Genzyme srl, a
wholly-owned subsidiary of the General Division located in Italy, acquired
certain assets of Omnia Res srl for approximately $700,000, of which
approximately $100,000 was recorded as goodwill. These acquisitions were
accounted for as purchases.

Accordingly, the associated net assets and operations have been included in the
General Division's financial statements since the acquisition dates. Pro forma
information is not presented since the impact of the acquisition on financial
statement periods prior to the acquisitions is not material.

         In July 1994, the General Division paid approximately $6,100,000 for
newly-issued shares of common stock representing 51% of the outstanding common
stock of Sygena A.G. ("Sygena"), a Swiss manufacturer of high performance
chemicals used in the development of pharmaceuticals. Based on certain put and
call options in the Acquisition Agreement, which effectively ensure the
purchase by the General Division of the remaining outstanding shares during the
period from July 1, 1996 through June 30, 1999, the General Division accounted
for the acquisition as a purchase of all of the outstanding shares of Sygena,
and recorded a deferred liability at a present value of approximately 8,600,000
Swiss francs (approximately 9,400,000 Swiss francs or $8,129,000 at December    
31, 1995) for the purchase of the remaining shares. The excess purchase price
over the net assets acquired was approximately 5,399,600 Swiss francs
(approximately $4,120,000) and was recorded as goodwill. The net assets and
operations of Sygena have been included in the General Division's financial
statements from the date of acquisition. Pro forma information is not presented
since the impact of the acquisition on financial statement periods prior to the
acquisition is not material.

         On December 15, 1994, the General Division acquired BioSurface
Technology, Inc. ("BioSurface") by issuing .575 of one share of TR Stock for
each share of BioSurface common stock. In the aggregate, 5,000,000 shares of TR
Stock, valued at $25,312,500, were issued representing 50% of the initial equity
interest in GTR. The acquisition was accounted for as a purchase. Accordingly,
the associated net assets and operations of BioSurface have been included in the
General Division's financial statements since the date of acquisition. The
excess of the purchase price over the fair market value of the net assets
acquired, $11,215,000, was allocated to in-process research and development and
charged to operations. Pro forma information is not presented since the impact
of the acquisition on financial statement periods prior to the acquisition is
not material.

         The following summary, prepared on a pro forma basis, presents the
consolidated results of operations as if BioSurface had been acquired at the
beginning of the periods presented. This pro forma summary does not necessarily
reflect the results of operations as they would have been if Genzyme and
BioSurface constituted a single entity during the periods presented and is not
necessarily indicative of results which may be obtained in the future.

         In August 1993, the General Division acquired 502,512 shares of the
Series E Convertible Preferred Stock (the "Series E Stock") of Univax Biologics,
Inc., for $5.0 million in connection with an agreement to develop and
commercialize certain products. Upon the achievement of specified clinical
milestones, the General Division is committed to making future milestone
payments. In November 1995, Univax merged with North American Biologicals,
Inc.("NABI") and in connection with the merger the General Division received
526,315 shares of NABI

common stock in exchange for the Series E Stock. The investment is classified as
available-for-sale and is included in "Other noncurrent assets" in the
consolidated balance sheets at fair market value. At December 31, 1995, this
value was approximately $5.7 million compared to a value of $2.7 million at
December 31, 1994. At that time, General Division believed the decline in value
was temporary and accordingly, an unrealized loss of approximately $2,300,000
was recorded as a charge to Stockholders' equity.

         In September 1993, the General Division acquired 714,286 shares of
common stock of Argus Pharmaceuticals, Inc. ("Argus") for $5.0 million in
connection with an agreement to develop and commercialize certain products. Upon
the achievement of certain specified clinical milestones, the General Division
is committed to making future milestone payments and an additional $5.0 million
investment in Argus. In August 1994, pursuant to the Common Stock Purchase
Agreement, Argus delivered to the General Division an additional 132,325 shares
resulting in a total of 846,611 shares held by the General Division. The
investment is classified as available-for-sale and is included in "Other
noncurrent assets" in the combined balance sheets at fair market value. At
December 31, 1994, this value was approximately $1.8 million. The General
Division believed that a portion of the impairment in the value of the
investment in Argus was "other than temporary" and accordingly, a loss of
approximately $3.3 million was charged to operations in 1994. In September 1995,
Argus combined with Triplex Pharmaceuticals and Oncologix to form Aronex. In
connection with this merger, the common stock of Argus was redesignated as
common stock of Aronex. At December 31,1995 the value of this investment was
$3.7 million.

         Pursuant to the Common Stock Purchase Agreement (the "Agreement") dated
as of June 24, 1994 between the General Division and Celtrix Pharmaceuticals,
Inc. ("Celtrix"), the General Division acquired 1,550,388 restricted shares,
approximately 11.5% of the common stock of Celtrix outstanding after the
acquisition, for $10.0 million. In November 1994, Celtrix announced a delay in
the commercialization of an application of a key product and in February 1995,
Celtrix announced that it had halted all studies related to another of its key
development products. These announcements resulted in a decline in the fair
market value of the General Division's investment. The General Division believed
that a portion of the impairment in the value of the investment in Celtrix was
"other than temporary". Accordingly, a loss of approximately $6.1 million was
charged to operations in 1994. In 1995, Celtrix exercised its option to require
the Company to purchase additional shares of Celtrix at fair market value. As a
result in December 1995, the General Division acquired an additional 1,472,829
shares at $3 per share. The investment is classified as available-for-sale. At
December 31, 1995, this value was approximately $7.7 million.

         Gross realized losses included in investment income for 1995 were
$110,000. Net realized gains included in investment income for 1994 and 1993 
were $1,430,000 and $1,647,000, respectively. Gross unrealized gains in the
investment portfolio at December 31, 1995 were $2,073,000. Gross unrealized
losses in the investment portfolio at December 31, 1994 were $5,449,000.

         In July 1993, GTC, a wholly-owned subsidiary of the Company
specializing in transgenic technology which was incorporated in February 1993,
completed an initial public offering of 1,500,000 shares of its common stock
priced at $8.00 per share. The offering resulted in an increase in the value of
the Company's investment in GTC of $7.6 million which was recorded as an
increase to additional paid-in capital. At December 31, 1993, the Company owned
4,000,000 shares or approximately 73% of the outstanding common stock of GTC.

              NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)


         On October 1, 1994, GTC acquired TSI Corporation ("TSI") in a merger
transaction in which GTC issued two-tenths (0.2) of one share of GTC common
stock for each share of TSI common stock, in a transaction accounted for as a
purchase. As a result of the acquisition, the Company's percentage ownership of
GTC common stock declined from approximately 73% to approximately 40%.
Accordingly, the General Division began accounting for its investment in GTC
under the equity method.

         In February 1995, GTC exercised its option to sell to the General
Division 500,000 additional shares of GTC common stock at a price of $8.00 per
share. The $4.0 million acquisition cost has been added to the General
Division's equity investment in this subsidiary. In June 1995, the General
Division converted approximately $4.0 million of GTC debt into equity through
the acquisition of 1.3 million shares of GTC common stock. In July 1995, GTC
acquired Biodevelopment Laboratories, Inc. ("BDL"). In connection with the
transaction, the General Division issued approximately 34,000 shares of General
Division Stock to former stockholders of BDL in exchange for approximately
475,000 shares of newly issued GTC stock. In total, GTC issued approximately
1,207,000 shares of its common stock in the transaction, resulting in a decrease
in the General Division's interest in GTC to 48.2%. Also as part of the BDL
transaction, the Company guaranteed a $7.5 million line of credit from a
commercial bank in return for warrants to purchase 145,000 shares of GTC stock.

         As of December 31, 1995, GTC had $6.0 million outstanding under this
line of credit. GTC had a working capital deficiency of approximately $25.1
million at December 31, 1995 and had an operating loss of approximately $4.1
million for the year then ended.  Although GTC is actively seeking other 
sources of financing and is directing substantial efforts to generating
positive cash flow, it is at least reasonably possible that GTC will not
generate sufficient cash flows to fund its ongoing operations and will not be
able to repay amounts outstanding under the line of credit. If this occurs, the
General Division will be responsible for at least a portion of the amounts
outstanding. (See Note R)

         The fair market value of the GTC shares, based on quoted market prices,
was $27,601,000 at December 31, 1995. The Company reported equity in GTC's
losses of $1,810,000 in 1995. Following are condensed financial data of GTC:

         The General Division is constructing a mammalian cell production
facility in Boston, Massachusetts which will be used to produce a recombinant
form of Ceredase(R) enzyme ("Cerezyme(R)") and other products. The facility is
expected to cost approximately $151 million plus an additional $23 million of
Cerezyme(R)

process validation and optimization costs. The facility is expected to be
validated and placed into service in 1996. As of December 31, 1995, the General
Division had capitalized, and included in construction in progress,
approximately $151,000,000 of expenditures related to this building and
approximately $33,472,000 of process validation and optimization costs related
to this and other facilities. In 1995, 1994 and 1993, the General Division
capitalized approximately $9.0, $9.2 and $4.7 million of interest costs,
respectively, relating to this and other facility construction.

         In June 1994, the General Division acquired its Mountain Road facility
in Framingham, Massachusetts for $26.9 million of which $25.1 million was
allocated to buildings and $1.8 million was allocated to land based on appraised
values. The General Division funded the purchase with $1.2 million in cash,
settlement of a $4.2 million note receivable (including accrued interest) from
the landlord of the facility and the proceeds of a $21.5 million term loan from
a bank (See Note J.)

                  In 1991, the Company issued 6 3/4% Convertible Subordinated
Notes due October 1, 2001 in the aggregate principal amount of $100,000,000. The
notes are convertible into General Division Stock and TR Stock at any time at a
conversion price of $52.875 and, under certain circumstances, may be redeemed by
the Company. Net proceeds from the debentures were $97,250,000. Deferred
financing costs of $2,750,000, classified as "Other noncurrent assets" on the
combined balance sheets, are being amortized to expense over the term of the
debt issue. As of December 31, 1995, the debentures had a market value of

approximately $125 million (See Note R).

         On December 21, 1993, the Company borrowed $39,000,000, under a Credit
Agreement (the "Agreement") with a bank. The interest rate in effect at December
31, 1994 was 6.2875%. The loan was repaid January 6, 1995.

         The mortgage note due June 1999 is collateralized by land and buildings
with a net book value of $29,108,000 at December 31, 1995, bears interest at
7.73% annually, and is payable monthly based on a twenty year direct reduction
amortization schedule, with the remaining principal due June 13, 1999.

         The mortgage note maturing November 2014 is collateralized by land and
buildings with a net book value of $5,188,000 at December 31, 1995 and bears
interest at 10.5%. The mortgage note maturing January 2008 provides the bank
with a "call or review" feature at the end of the first 60 month period,
allowing the bank to adjust the note under specific circumstances. This note
bears interest at a variable rate of prime plus 1% and is collateralized by land
and fixtures. Principal and interest are payable monthly on both of these notes.

         The Company maintains a $15.0 million line of credit with Fleet Bank of
Massachusetts, the entire amount, of which, remained available at December 31,
1995.

Operating Leases

         Total rent expense under operating leases was $8,603,000, $8,578,000,
and $8,734,000 in 1995, 1994 and 1993 respectively. The General Division leases
facilities and personal property under certain operating leases in excess of one
year.

Neozyme I and II

         In 1992, the General Division entered into a development contract with
Neozyme II whereby the General Division was engaged to perform all research,
development and clinical testing activities related to products and programs for
which Neozyme II was licensed. The General Division received $5,000,000 in 1992
under the technology license agreement pursuant to which the General Division
granted Neozyme II exclusive rights to manufacture and sell the products
developed under the technology license agreements.

         The funds for Neozyme II's development contract were raised by the 
sale of 2,415,000 units for net proceeds of $78,038,000. Each unit consisted of
one share of Neozyme II callable common stock, one Series N warrant and one
callable warrant to purchase one share of General Division Stock and .135 shares
of TR Stock. Included in accounts receivable as of December 31, 1995 and 1994
was $2,469,000 and $729,000, respectively, due from Neozyme II.

         The General Division has an option to purchase all of the shares of 
the Neozyme II callable common stock for cash, shares of General Division Stock
or any combination thereof (determined at Genzyme's sole discretion) at 
$117.00 per share from January 1, 1996 through December 31, 1996, subject to    
downward adjustment if exercised before December 31 in any exercise period. Due
to the uncertainties inherent in the very early stages of the research into
CFTR, management did not consider the exercise of the option probable and,
accordingly, charged to operations in 1992 the $16,905,000 appraised fair value
of this purchase option.

         In December 1993, the General Division exercised its option to 
purchase one of the two remaining research programs being funded by Neozyme I 
(a special purpose accelerated research corporation created in 1990) for a
purchase price of $24,000,000 in cash. As part of the purchase, the General
Division retained $0.6 million to fund the costs of the Neozyme I dissolution
which occurred in 1994, and any future tax liabilities. This transaction was
accounted for as a purchase of in-process research and development and its 
value charged to operations in 1993.

The Surgical Aids Partnership

         In September 1989, the General Division entered into a development
contract valued at approximately $37,000,000 with the Surgical Aids Partnership
("the Partnership") to perform research and development of products based on
hyaluronic acid for use as surgical aids to reduce the incidence and severity of
postoperative adhesions. The General Division received a technology license fee
of $1,500,000 in November 1989 and was reimbursed its development costs plus 10%
through the first quarter of 1994 when the Partnerships funds were exhausted.
The General Partner believes that additional funds will be required to complete
the development, clinical testing and commercialization of the Partnership's
products. Although the General Division is not obligated to provide additional
funding, the Purchase Option (see below) terminates unless the General Division
commits on an annual basis to provide funding for continuation of the research
and development programs for the next twelve month period or until receipt of
FDA approval of one of the Partnership's products is obtained, whichever is
shortest. The General Division spent approximately $6.4 million and $6.5 million
on the Partnership's development programs in 1995 and 1994, respectively, and
has committed to fund the programs in 1996, expecting to spend approximately
$7.9 million (unaudited). Included in accounts receivable as of

December 31, 1994 was $199,000 due from the Partnership.

         The General Division also entered into a joint venture agreement with
the Partnership to manufacture and market the Partnership's products, to share
in the profits, to make non-interest bearing loans for working capital
deficiencies, and to make capital contributions as deemed necessary by the
Partnership in connection with the business of the joint venture. The exact
amounts and timing of these expenditures and contributions cannot be determined
at this time.

         The General Division also obtained an option (the "Purchase Option") to
purchase all of the outstanding partnership interests for a payment of
approximately $26,000,000 in cash, General Division Stock or a combination
thereof determined at Genzyme's sole discretion, plus future royalty payments.
The Purchase Option does not become exercisable until at least twenty-four
months after the first commercial sale of a product of the Partnership.

         Deferred revenue from related parties at December 31 includes the

NOTE L  GOODWILL IMPAIRMENT AND RESTRUCTURING COSTS

         In the fourth quarter of 1993, the General Division recognized an
expense of $23.7 million to reduce the carrying value of intangibles to the
realizable value based on revised estimates of continuing value and future
benefits. The majority of the write-off, $21.9 million, related to the goodwill
recorded in connection with the acquisition of Genetic Design, Inc. ("GDI") in
June 1992. The goodwill write-off was based on an analysis of GDI's business
conducted in the fourth quarter of 1993, including the loss of significant state
public paternity testing contracts, which indicated that the environment for
public paternity testing, GDI's primary business market, had changed
significantly since the acquisition, and therefore called into question the
carrying value of the acquisition-related GDI goodwill. The business review
disclosed the development of a competitive environment which emphasized cost
rather than service and performance, intense price competition from a major
competitor, a general reduction in the ordering of identity tests due to
governmental budgetary restrictions and uncertainties as to the level of federal
funding of state testing activities, a cost structure at GDI which made it
difficult for GDI to continue as an effective competitor in a slow-growth,
cost-driven environment and the decreased likelihood of sufficient support in
Congress for passage of additional social legislation which would significantly
increase federal funding of state testing activities. These changed
circumstances resulted in a determination to reduce the carrying value of GDI
goodwill to zero at the end of 1993. The remaining $1.8 million of write-offs
consisted of approximately $1.1 million of patent rights resulting from the
purchase of Enzymatix Ltd. by Genzyme Ltd. (UK) and approximately $0.7 million
of intangible assets resulting from the acquisition of a clinical testing
laboratory by IG. Also in the fourth quarter of 1993, the General Division
incurred restructuring charges of $2.8 million related to the consolidation of
laboratory operations in its Diagnostic Services business. The expenses were
related to severance of $1.2 million for an estimated 45 employees; lease costs
of $0.8 million;

equipment movement and disposal of $0.2 million; costs incurred to restructure
the General Division's paternity product line of $0.2 million and other costs of
$0.4 million. All costs were cash expenditures in 1994. The restructuring plan
was undertaken to consolidate lab testing services into the General Division's
most cost-effective testing locations, transfer virtually all accounting
functions to the General Division's headquarters and streamline the paternity
product line at GDI.

NOTE M  COMMITMENTS AND CONTINGENCIES

         In December 1994, the General Division fully settled litigation brought
by Granada BioSciences, Inc., Houston, Texas, by payment of $1,980,000 in cash.
The dispute arose out of a contract between Granada R&D Ventures, a predecessor
of Granada BioSciences, and Integrated Genetics, prior to its merger with the
General Division in 1989, regarding development of recombinant fertility
hormones for cows and other animals.

         From time to time the General Division has been subject to legal
proceedings and claims arising in connection with its business. At December 31,
1995, there were no asserted claims against the General Division which, in the
opinion of management, if adversely decided would have a material adverse effect
on the General Division's financial position and results of operations.

         Genzyme's commitment to allocate up to $30 million from the General
Division to fund the operations of GTR was eliminated when GTR sold newly issued
TR Stock to the public in September, 1995; however, Genzyme has the right to
make voluntary allocations of up to $30 million from the General Division to
GTR. Such allocations would reduce the Funding Commitment on a dollar-for-dollar
basis and increase the number of TR Designated Shares at the rate of one share
for each $10 so allocated.

</TABLE>


        At December 31, 1995 and 1994, valuation allowances of $20.6 million
and $32.2 million, respectively, were recorded to offset a portion of the
deferred tax assets related to the realization of net operating loss
carryforwards, and deductions relating to the purchase of in-process research
and development and the future disposition of certain stock purchase options.
Realization of the net deferred tax asset is dependent on generating sufficient
taxable income prior to the expiration of loss carryforwards. Although
realization is not assured, management believes that it is more likely than not
that all of the net deferred tax assets will be realized. The amount of the
deferred tax asset considered realizable, however, could be reduced in the near
term if estimates of future taxable income during the carryforward period are
reduced.

        A total of $1.5 million of the valuation allowance relates to tax
assets arising from the IG Labs acquisition (See Note D). If any portion of this
tax asset is ultimately realized, the remaining goodwill relating to the IG Labs
acquisition will be reduced accordingly.

        At December 31, 1995, the General Division had U.S. net operating loss
carryforwards of $26.4 million for income tax purposes. These carryforwards
expire from 2000 to 2010. Utilization of tax net operating loss carryforwards
may be limited under section 382 of the Internal Revenue Code of 1986.

        At December 31, 1995, the General Division also had U.K. operating loss
carryforwards for income tax purposes of approximately $2.9 million which are
available indefinitely to offset future taxable income in the U.K.

NOTE O  BENEFIT PLANS

        The General Division has defined-benefit pension plans covering
substantially all the employees of its foreign subsidiaries. Pension expense for
1995, 1994 and 1993 was $498,000, $266,000 and $206,000, respectively. Pension
costs are funded as accrued. Actuarial and other disclosures regarding the plans
are not presented because they are not material.

        Genzyme has a domestic employee savings plan under Section 401(k) of
the Internal Revenue Code covering substantially all employees of the General
Division. The plan allows employees to make contributions up to a specified
percentage of their compensation, a portion of which are matched by the General

NOTE P FINANCIAL INFORMATION BY GEOGRAPHIC AREA AND SIGNIFICANT CUSTOMERS AND
SUPPLIERS

         The General Division operates in one industry, the human healthcare
industry and manufactures and markets its products in two major geographic
areas, the United States and Europe. The General Division's principal
manufacturing facilities are located in the United Kingdom and the United
States.

         The General Division purchases products from its United Kingdom 
subsidiaries for sale to United States customers. Transfer prices from the 
foreign subsidiaries are intended to allow the United States parent to produce
profit margins commensurate with its sales and marketing effort. The 
Netherlands subsidiary is the European distributor of the General Division's 
therapeutic products. Certain information by geographic area follows (dollars

               NOTES TO COMBINED FINANCIAL STATEMENTS (Continued)

         In January 1996, Genzyme made a conditional offer to acquire
substantially all the assets of the Partnership for General Division Stock
valued at $93.0 million.

         In February 1996, GTC obtained a short-term loan in the amount of
$950,000 from Genzyme. The loan is due on March 31, 1996 and accrues interest at
a rate of 6 1/2% per annum.

         In February 1996, the General Division signed a definitive agreement to
acquire Genetrix Inc., a privately held genetic testing laboratory based in
Phoenix, Arizona, in a tax-free exchange of General Division Stock valued at
approximately $36.8 million. Genetrix Inc. will be merged with the General
Division's Integrated Genetics diagnostic services business. The transaction
will be accounted for as a pooling of interests.

         In February 1996, the General Division announced a planned redemption 
of its 6 3/4% Convertible Subordinated Notes. All holders elected to convert
their notes into shares of General Division Stock and TR Stock. Holders of the 
notes received 18.913 shares of General Division Stock and 2.553 shares of TR 
Stock in conversion of each $1,000 note.  Supplementary earnings per share for
the General Division which gives effect to the conversion of the notes as if
such conversion took place at the beginning of each period presented, is equal
to fully diluted earnings per share.

         In March 1996, an advisory panel to the U.S. Food and Drug
Administration ("the FDA") recommended that Genzyme be granted approval to
market one of the HA Products, Seprafilm(TM) bioresorbable membrane. The panel's
recommendation will be considered by the FDA in its final review of Genzyme's
premarket approval application.

         In March 1996, GTC entered into a Convertible Debt and Development
Funding Agreement with the General Division under which the General Division
agreed to provide a revolving line of credit in the amount of $10 million and
has agreed to fund development costs of the Antithrombin III ("AT-III") program
through March 31, 1997. Under the Agreement GTC granted to the General Division
co-marketing rights to AT-III in all territories other than Asia subject to
negotiation and execution of a development and supply agreement between the
parties prior to 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 day
period ending two days before the Conversion at GTC's option 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 by Genzyme at any time for up to the full amount
outstanding.

         In March 1996, the Board of Directors voted, subject in each case to
the approval of the stockholders, to adopt two amendments to the Company's 1990
Equity Incentive Plan (the "Equity Plan"). These amendments would increase the
aggregate number of shares of General Division Stock that may be subject to
grants under the Equity Plan from 7,600,000 to 9,900,000 subject to adjustment
for stock splits, stock dividends and certain transactions affecting the
Company's capital stock.

         REPORT OF INDEPENDENT ACCOUNTANTS

         To the Board of Directors and Stockholders
         of GENZYME CORPORATION:

                  We have audited the accompanying combined balance sheets of
         Genzyme Tissue Repair Division (as described in Note A) as of December
         31, 1995 and 1994, and the related combined statements of operations
         and cash flows and the combined financial statement schedule for each
         of the three years in the period ended December 31, 1995. The combined
         financial statements and financial statement schedule are the 
         responsibility of Genzyme Corporation's management. Our responsibility
         is to express an opinion on these combined financial statements and 
         financial statement schedule based on our audits.

                  We conducted our audits in accordance with generally accepted
         auditing standards. Those standards require that we plan and perform
         the audit to obtain reasonable assurance about whether the financial
         statements are free of material misstatement. An audit includes
         examining, on a test basis, evidence supporting the amounts and
         disclosures in the financial statements. 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 combined financial statements of Genzyme
         Tissue Repair Division present fairly, in all material respects, the
         financial position of Genzyme Tissue Repair Division as of December 31,
         1995 and 1994 and the results of its operations and its cash flows for
         each of the three years in the period ended December 31, 1995, in
         conformity with generally accepted accounting principles. In addition,
         in our opinion, the combined financial statement schedule taken as a
         whole presents fairly, in all material respects, the information
         required to be included therein.

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

                         GENZYME TISSUE REPAIR DIVISION
               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

NOTE A  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Business: Genzyme Tissue Repair Division ("GTR"), a division of Genzyme
Corporation (the "Company" or "Genzyme"), develops and commercializes products
and services for the prevention or repair of tissue injury as a consequence of
accidental or disease related trauma. GTR uses cell, enzyme, growth factor and
matrix technologies to develop products that will augment or positively modify
naturally-occurring biological processes involved in tissue repair.

         Basis of Presentation: The approval effective December 16, 1994 (the
"Effective Date") by the stockholders of Genzyme of the Genzyme Stock Proposal
as described in Genzyme's Prospectus/Proxy Statement dated November 10, 1994
resulted in the redesignation of Genzyme's common stock. The outstanding shares
of Genzyme common stock were redesignated as General Division Common Stock
("General Division Stock") on a share-for-share basis and a second class of
common stock, designated as Tissue Repair Division 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 stockholders of record on October 14,
1994. General Division Stock and TR Stock provide stockholders with separate
securities which are intended to reflect the performance of the Genzyme General
Division (the "General Division") and GTR, respectively.

         Net income (loss) per common share has been included in the Statements
of Operations. For the purpose of computing net loss per common share of TR
Stock, the number of shares of TR Stock prior to the Effective Date are assumed
to be the total number of shares of Genzyme common stock multiplied by .135.

         Dividends to the holders of TR Stock will be limited to the lesser of
funds of Genzyme legally available for the payment of dividends and the
Available Tissue Repair Dividend Amount, as defined in Genzyme's Articles of
Organization, as amended. Although there is no requirement to do so, the Board
would declare and pay dividends on TR Stock, if any, based primarily on the
earnings, financial condition, cash flow and business requirements of GTR. There
is currently no intention of paying dividends.

         Genzyme, subject to certain conditions, has the right to exchange each
outstanding share of TR Stock for any combination of cash and/or shares of
General Division Stock at a 30% premium over Fair Market Value. In addition,
following a disposition of all or substantially all assets of GTR, the shares of
TR Stock are subject to mandatory exchange by Genzyme for cash and/or shares of
General Division Stock at a 30% premium over Fair Market Value as determined by
the trading prices during a specified period prior to public announcement of the
disposition. Shares of General Division Stock are not subject to either optional
or mandatory exchange.

         Holders of General Division Stock and TR Stock each are entitled to one
vote per share and vote together as a single class on all matters as to which
common stockholders generally are entitled to vote. Except in limited
circumstances provided under Massachusetts law and in Genzyme's Articles of
Organization, as amended, and in the management and accounting policies adopted
by Genzyme's Board of Directors (the "Board"), holders of each class of common
stock will have no rights to vote on matters as a separate class. Separate
meetings of the holders of each class of common stock will not be held. If, when
a stockholder vote is taken on any matter as to which a separate vote by either
class is not required and the holders of either class of common stock would have
more than the number of votes required to approve any such matter, the holders
of that class will control the outcome of the vote on that matter.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

         The financial statements of GTR include the financial position, results
of operations and cash flows of the tissue repair operations of Genzyme. GTR's
financial statements are prepared using the amounts included in Genzyme's
consolidated financial statements. Corporate allocations reflected in these
financial statements are determined based upon methods which management believes
to be reasonable (see Note B).

         Genzyme provides holders of TR Stock separate financial statements,
management's discussion and analysis, descriptions of businesses and other
relevant information for GTR in addition to consolidated financial information
of Genzyme. Notwithstanding the attribution of assets and liabilities (including
contingent liabilities) between the General Division and GTR for the purposes of
preparing their respective historical and future financial statements, this
attribution and the change in the capital structure of Genzyme as a result of
the approval of the Genzyme Stock Proposal does not affect legal title to the
assets or responsibility for the liabilities of Genzyme or any of its
subsidiaries. Holders of TR Stock are shareholders of Genzyme, which continue to
be responsible for all of its liabilities. 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.
Accordingly, Genzyme's consolidated financial statements should be read in
connection with GTR's financial statements.

         Except as stated in the amended articles, the accounting policies
applicable to the preparation of the financial statements of GTR may be modified
or rescinded at the sole discretion of the Board without the approval of the
shareholders, although there is no intention to do so.

         Principles of Combination: The accompanying combined financial
statements reflect the combined accounts of all of Genzyme's tissue repair
businesses. All material intercompany items and transactions have been
eliminated in combination.

         Use of Estimates: The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
certain estimates and assumptions that effect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reported period. Actual results could differ from those estimates.

         Cash and Cash Equivalents: Cash equivalents, consisting principally of
money market funds and municipal notes purchased with initial maturities of
three months or less, are valued at cost plus accrued interest, which
approximates market.

         Investments: Short-term investments include all investments with
remaining maturities of twelve months or less. Long-term investments include all
investments with remaining maturities greater than twelve months. GTR classifies
its equity investments as available-for-sale and its investments in debt
securities as either held-to-maturity or available-for-sale based on facts and
circumstances present at the time the investments are purchased. As of December
31, 1995, the Company classified all investments, consisting solely of debt
securities, as available-for-sale (See Note F - Investments).

         Fair Value of Financial Instruments:  The fair value of investments is
obtained from market quotations and is disclosed in Note F.

         Inventories:  Inventories are valued at the lower of cost (first-in,

first-out method) or market.

         Property, Plant and Equipment: Property, plant and equipment are stated
at cost. Provision for depreciation is computed using the straight-line method
over the estimated useful lives of the assets (three to ten years for plant and
equipment, five to seven years for furniture and fixtures, and twenty-five to
forty years for buildings). Leasehold improvements are amortized over the lesser
of the useful life or the term of the respective lease.

         Revenue Recognition: GTR's two commercial tissue repair services are
autologous epidermal skin grafts produced using the Epicel[SM] Service and the
culturing of autologous cartilage cells using the CARTICEL[SM] Service. GTR
recognizes service revenue at the time skin grafts or cartilage cells are
shipped. Cancellation charges may be assessed upon the cancellation of an
Epicel[SM] order. These charges are dependent upon order size and stage of skin
graft growth and are recognized upon order cancellation and when collection is
determined to be probable. Revenues from research and development contracts are
recognized over applicable contractual periods as specified by each contract.
Non-refundable technology license fees are recognized as revenue upon
consummation of the related agreement.

         Research and Development: Research and development costs are expensed
in the period incurred. Costs of purchased technology which management believes
has not demonstrated technological feasibility and for which there is no
alternative future use are charged to expense in the period of purchase.

         Income Taxes: GTR uses the asset and liability method of accounting for
deferred income taxes. The provision for income taxes includes income taxes
currently payable and those deferred because of temporary differences between
the financial statement and tax bases of assets and liabilities. See Note B for
allocation of Genzyme's income taxes to GTR.

         Net Loss Per Share: The method of calculating earnings per share for TR
Stock reflects the terms of the Articles of Organization, as amended, which
provide that dividends may be declared and paid only out of the lesser of funds
of Genzyme legally available therefore and each division's Available Dividend
Amount, as defined. For the purpose of computing net income per common share of
TR Stock for periods prior to December 12, 1994, the number of shares and share
equivalents of TR Stock prior to the Effective Date are assumed to be the same
as the total number of shares and share equivalents of Genzyme common stock
multiplied by .135. GTR computes income per share by dividing the income
attributable to TR Stock by the weighted average number of shares of TR stock
and dilutive common stock equivalents and other potentially dilutive securities
outstanding during the applicable period. Income attributable to TR Stock equals
GTR's net income or loss for the relevant period determined in accordance with
generally accepted accounting principles in effect at such time, adjusted by the
amount of tax benefits allocated to or from GTR pursuant to the accounting
policies adopted by the Board. The accounting policies provide that, as of the
end of any fiscal quarter of Genzyme, any projected annual tax benefit
attributable to any division that cannot be utilized by such division to offset
or reduce its current or deferred income tax expense may be allocated to the
other division without any compensating payment or allocation. Net loss
attributable to TR Stock and net loss per common and common equivalent share for
the years ended December 31, 1993 and 1994 give effect to the provisions of the
management and accounting policies adopted by the Board in connection with the
creation of GTR and, accordingly, are pro forma presentations.

         Accounting for Stock-Based Compensation: Statement of Financial
Accounting

                         GENZYME TISSUE REPAIR DIVISION
               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

Standards No. 123, "Accounting for Stock-Based Compensation" (SFAS 123"), will
require the Company to either elect expense recognition under SFAS 123 or its
disclosure-only alternative for stock-based employee compensation. The expense
recognition provision encouraged by SFAS 123 would require fair value-based
financial accounting to recognize compensation expense for employee stock
compensation plans. SFAS 123 must be adopted in the Company's fiscal 1996
financial statements with comparable disclosures for the prior year. The Company
has determined that it will elect the disclosure-only alternative permitted
under SFAS 123. The Company will be required to disclose pro forma net income
and pro forma earnings per share in the footnotes using the fair value based
method beginning in fiscal 1996 with comparable disclosures for fiscal 1995. The
Company has not determined the impact of these pro forma adjustments to its net
income or earnings per share.

         Financial Instruments: Financial instruments that potentially subject
the Company to significant concentrations of credit risk consist principally of
cash and cash equivalents, current and non-current investments. The Company
generally invests its cash investments in investments-grade securities.

         Uncertainties: The Company is subject to risks common to companies in
the Biotechnology industry including, but not limited to, development by the
Company or its competitors of new technological innovations, dependence on key
personnel, protection of proprietary technology, and compliance with FDA
government regulations.

NOTE B  RELATED PARTY TRANSACTIONS

         The following policies may be modified or rescinded by action of the
Board, or the Board may adopt additional policies, without approval of the
shareholders of Genzyme, although the Board has no present intention to do so.
Genzyme allocates certain corporate general and administrative expenses,
research and development expense and income taxes in accordance with the
policies described below.

         Financial Matters: As a matter of policy, the Company manages the
financial activities of the General Division and GTR on a centralized basis.
These financial activities include the investment of surplus cash; the issuance,
repayment and repurchase of short-term and long-term debt and the issuance and
repurchase of common stock. At December 31, 1995, the Company attributed none of
its short-term and long-term debt to GTR based upon the specific purpose for
which the debt was incurred and the cash flow requirements of GTR. Accordingly,
none of the Company's interest expense has been allocated to GTR. The Company
believes this method of allocation to be equitable and a reasonable estimate of
such costs as if GTR operated on a stand-alone basis.

         To the extent borrowings are deemed to occur between GTR and the
General Division, intercompany accounts have been established bearing interest
at the rate in effect from time to time under the Company's unsecured credit
lines or, if no such credit lines exist, at the prime rate charged by The First
National Bank of Boston from time to time. To date no such borrowings have
occurred, however at December 31, 1995 GTR owed the General Division $2.0
million for services rendered in the normal course of business.

         Shared Services: Genzyme's corporate general and administrative
functions and certain sales and marketing efforts related to foreign market
penetration are performed by the General Division. General, administrative,
sales and marketing expenses have been allocated to GTR based upon utilization
of such services as if the General Division and GTR operated on a stand-alone
basis.

                         GENZYME TISSUE REPAIR DIVISION
               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

Management believes that such allocation is a reasonable estimate of such
expenses. These allocations for the years ended December 31, 1995, 1994 and 1993
were $4,355,000, $833,000 and $701,000, respectively. In addition, costs
incurred by the General Division related to research and development for GTR
products are charged to GTR. These charges for the years ended December 31,
1995, 1994 and 1993 were $4,730,000 $3,331,000 and $2,805,000, respectively.

         Income Taxes: GTR is included in the consolidated U.S. federal income
tax return filed by Genzyme. Genzyme allocates current and deferred taxes to its
divisions by applying the provisions of FAS 109 to each division as if it were a
separate taxpayer. Accordingly, the realizability of deferred tax assets is
assessed at the GTR level. The sum of the amounts calculated for individual
divisions of Genzyme may not equal the consolidated amount under this approach.
GTR reports current and deferred tax assets and liabilities as a net
intercompany payable or receivable.

         Under the terms of the Genzyme Stock Proposal, as of the end of any
fiscal quarter of Genzyme Corporation, any projected tax benefit attributable to
any division that cannot be utilized by such division to offset or reduce its
current or deferred income tax expense may be allocated to any other division
without any compensating payment or allocation. The treatment of such allocation
for purposes of earnings per share computation is discussed in Note A.

         Inter-Division Asset Transfers. The Board may at any time and from time
to time reallocate any program, product or other asset from one division to any
other division. All such reallocations will be done at fair market value,
determined by the Board, taking into account, in the case of a program under
development, the commercial potential of the program, the phase of clinical
development of the program, the expenses associated with realizing any income
from the program, the likelihood and timing of any such realization and other
matters that the Board and its financial advisors deem relevant. The
consideration for such reallocation may be paid by one Division to another in
cash or, in lieu of cash or other consideration, the Board may elect to account
for a reallocation of assets from GTR to the General Division as an increase in
the General Designated Shares and a reallocation of assets from the General
Division to GTR as either an increase in the TR Designated Shares or a reduction
in the General Designated Shares, if any, except that a reallocation of assets
from GTR to the General Division may not be accounted for as an increase in
General Designated Shares without a class vote of the holders of TR Stock.

         Immediately prior to the Effective Date, as defined in Note A,
approximately 15,791,000 shares of Genzyme common stock were reserved for
issuance under the Company's 1990 Equity Incentive Plan, 1988 Director Stock
Option Plan, 1990 Employee Stock Purchase Plan, outstanding warrants (the
"Warrants"), and conversion of the 6 3/4% Convertible Subordinated Notes Due
2001 (the "Notes").

         Pursuant to antidilution provisions in the agreements covering the
options, Genzyme has adjusted each option outstanding on the Effective Date to
provide for separation of the option into an option exercisable for General
Division Stock and an option exercisable for the number of shares of TR Stock
that the holder would have received if the holder had exercised the option
immediately prior to the Effective Date (with any resultant fractional shares of
TR Stock rounded down to the nearest whole number). Upon exercise of these
options, all proceeds will be allocated to the General Division (See TR
Designated Shares).

         The Warrants provide that the holder of the Warrant is entitled to
receive the number of shares of General Division Stock and TR Stock upon
exercise of the Warrant that the holder would have received if the holder had
exercised the Warrant immediately prior to the Effective Date.

         Pursuant to the indenture under which the Notes were issued, the
conversion privilege of the Notes was adjusted so that the holder of a Note
converted after the Effective Date will receive, in addition to the shares of
General Division Stock into which the Note is convertible, the same number of
shares of TR Stock as the holder would have received had the holder converted
the Note immediately prior to the Effective Date.

         In September 1995, GTR sold 3,000,000 shares of TR Stock to the public
at a price of $15 per share for net proceeds of $42.4 million after
underwriting discounts and commissions.

         At December 31, 1995, approximately 3,478,585 shares of TR Stock were
reserved for issuance under the 1990 Equity Incentive Plan as amended, the 1988
Director Stock Option Plan as amended, the 1990 Employee Stock Purchase Plan as
amended, outstanding warrants, and conversion of the Notes.

         Preferred Stock. Shares of Preferred Stock may be issued from time to
time in one or more series. The Board of Directors may determine, in whole or in
part, the preferences, voting powers, qualifications and special or relative
rights or privileges of any such series before the issuance of any shares of
that series. The Board of Directors shall determine the number of shares
constituting each series of Preferred Stock and each series shall have a
distinguishing designation.

         Stock Options. Pursuant to the Company's 1990 Equity Incentive Plan as
amended (the "Plan"), options may be granted to purchase an aggregate of
2,000,000 shares of TR Stock. The Plan allows the granting of incentive stock
and nonstatutory stock options at not less than fair market value at date of
grant, and stock appreciation rights, performance shares, restricted stock and
stock units to employees and consultants of the Company, each with a maximum
term of ten years. In addition, the Company has a 1988 Director Stock Option
Plan, as amended, pursuant to which nonstatutory stock options up to a maximum
of 70,000 shares of TR Stock, at a rate of 400 shares for each year of service
are automatically granted at fair market value to members of the Board of
Directors of the Company upon their election or reelection as Directors. All
options expire ten years after the initial grant date and are subject to various
vesting provisions.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

         At the Effective Date of the Genzyme Stock Proposal, Genzyme granted
initial options to purchase a total of 939,851 shares of TR Stock to employees
of the Company who will devote a substantial portion of their efforts to GTR.
These options, (i) had an exercise price of $4.75, the closing price of TR Stock
on the first date such shares were traded on the NASDAQ National Market System
or the closing price of such shares on the six-month anniversary of such date,
(ii) become exercisable 20% on the effective date of the grant and 20% on each
of the next four anniversaries thereof and (iii) have a term of ten years. At
the six month anniversary date the closing price of the TR Stock was $6.25 and
accordingly, compensation expense equal to 939,851 shares multiplied by the
difference in the exercise price of $4.75 and $6.25, the six month anniversary
price, will be recognized over the period of service of the holders. In 1995,
GTR recorded $882,000 of related compensation expense and will record the
balance of $505,000 over the next 3 years.

         Employee Stock Purchase Plan. The Company's 1990 Employee Stock
Purchase Plan allows employees to purchase the Company's stock at 85% of fair
market value. Under this plan 600,000 shares of TR Stock are authorized, of
which 269,920 and 3,613 shares of TR Stock were issued in 1995 and 1994,
respectively.

         Stock Rights. In 1989, the Company's Board of Directors issued a
dividend of one preferred stock purchase right (a "Common Stock Right") on each
share of Common Stock. At the Effective Date, the Rights Agreement under which
the rights were issued was amended and restated to reflect the change in the
capital structure of the Company and the Board declared a distribution to
holders of TR Stock of a right (a "TR Stock Right") on each outstanding share of
TR Stock. The Restated Rights Agreement provides that each General Division
Stock Right, which replaced the Common Stock Right, and each TR Stock Right,
when it becomes exercisable, will entitle the holder to purchase from the
Company (i) in the case of a General Division Stock Right, one one-hundredth of
a share of Series A Junior Participating Preferred Stock at a price of $52,
subject to adjustment, and (ii) in the case of a TR Stock Right, one
one-hundredth of a share of Series B Junior Participating Preferred Stock at a
price of $25, subject to adjustment. The rights expire on March 28, 1999.

         Stock Warrants. The Company has issued warrants which, when exercised,
grant the holders one share of General Division Stock and .135 shares of TR
Stock. These warrants were granted in exchange for the receipt of options by the
General Division to purchase the partnership interests of Genzyme Development
Partners, L.P. (the "Surgical Aids Partnership") the callable common stock of
Neozyme II Corporation ("Neozyme II"), and in connection to Genzyme's purchase
of the publicly-held shares of IG Laboratories, Inc.("IG") in exchange for IG
warrants. All proceeds from the exercise of these warrants will be allocated to
the General Division (see "TR Designated Shares"). The outstanding warrants were
issued under the following terms:

         TR Designated Shares. Pursuant to Genzyme's Articles of Organization,
as amended, TR Designated Shares are authorized shares of TR Stock which are not
issued and outstanding, but which the Board may from time to time issue, sell or
otherwise distribute without allocating the proceeds or other benefits of such
issuance, sale or distribution to GTR. At the Effective Date, 5,000,000 TR
Designated Shares were established. As a result of the distribution of
approximately 3,300,000 shares of TR Stock to holders of General Division Stock,
the number of TR Designated Shares were reduced by a corresponding amount. The
remaining 1,700,000 TR Designated Shares were reserved for issuance upon the
exercise of Genzyme stock options and warrants and the conversion of Genzyme's
convertible notes which were outstanding on the Effective Date. TR Designated
Share activity is summarized below:

Neozyme I

         In 1990, GTR entered into a development contract with Neozyme I,
whereby GTR was engaged to perform all research, development and clinical
testing activities related to products and programs in the field of the
Vianain(R) debriding product for which Neozyme I was licensed. GTR received
$549,000 in 1990 under a technology license agreement (the "Agreement") pursuant
to which GTR granted Neozyme I exclusive rights to manufacture and sell
Vianain(R). In July 1993, GTR received an additional technology license fee of
$2,000,000 from Neozyme I related to expansion of the field of the Vianain(R)
debriding product. In December 1993, GTR exercised its option to purchase the
Vianain(R) research program being funded by Neozyme I for a purchase price of
$25,000,000 in cash. The transaction was accounted for as a purchase of
in-process research and development and the value charged to operations in the
fourth quarter of 1993.

Celtrix Pharmaceuticals, Inc.

         In connection with the Common Stock Purchase Agreement dated June 24,
1994 between Genzyme and Celtrix Pharmaceuticals, Inc. ("Celtrix"), GTR entered
into a License and Development Agreement (the "License Agreement") with Celtrix.
The License Agreement granted GTR worldwide rights (excluding Asia) to
manufacture and market products based on Transforming Growth Factor Beta2 for
certain applications. In exchange, GTR agreed to fund development work relating
to the products at both Celtrix and the General Division and to make milestone
and royalty payments to Celtrix.

NOTE E  ACQUISITION OF BIOSURFACE TECHNOLOGY, INC.

         On December 15, 1994, Genzyme acquired BioSurface Technology, Inc.
("BST") by issuing .575 of one share of TR Stock for each share of BST common
stock. In the aggregate, 5,000,000 shares of TR Stock, valued at $25,312,500,
were issued representing 50% of the initial equity interest in GTR. The
acquisition was accounted for as a purchase. Accordingly, the associated net
assets and operations of BST have been included in GTR's financial statements
since the date of acquisition. The excess of the purchase price over the fair
market value of the net assets acquired, $11,215,000, was charged to in-process
research and development.

</TABLE>

         The deferred tax assets of GTR cannot be utilized by the Division to
offset or reduce current or deferred income tax expense. Accordingly, the
deferred tax assets have been allocated to the General Division.

         GTR reports current and deferred tax assets and liabilities as a net
intercompany payable or receivable.  GTR's 1995 tax expense has been funded by
Genzyme.

NOTE L  BENEFIT PLANS

         Genzyme has a domestic employee savings plan under Section 401(k) of
the Internal Revenue Code covering substantially all employees of GTR. The plan
allows employees to make contributions up to a specified percentage of their
compensation, a portion of which are matched by GTR. GTR made $35,587 and $0 in
contributions to the plan in 1995 and 1994, respectively.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

         Genzyme's former obligation to allocate up to $30 million in cash from
the General Division to GTR in the period through June 1998 (the "Funding
Commitment") was eliminated by the consummation of GTR's public offering on
September 22, 1995, which provided GTR with $42.4 million in net proceeds from
the offering after underwriting discounts. Notwithstanding the elimination of
the Funding Commitment, Genzyme still has an option to allocate to GTR, at $10
per TR Designated Share, up to $30 million from the General Division (the
"Purchase Option"). Consequently, a maximum of 3,000,000 of TR Designated Shares
may be issued in connection with the exercise of the Purchase Option.

NOTE O SUBSEQUENT EVENTS

         In January 1996, GTR acquired certain real estate in Framingham,
Massachusetts for $6.8 million in cash, of which $5.7 million was allocated to
buildings and $1.1 million was allocated to land based on appraised values.

         In March 1996, GTR utilized $8.0 million of the Company's $15.0 million
line of credit with Fleet Bank of Massachusetts.

         In March 1996, the Board of Directors voted, subject in each case to
the approval of the stockholders, to adopt two amendments to the Company's 1990
Equity Incentive Plan (the "Equity Plan"). These amendments would increase the
aggregate number of shares of shares of TR Stock that may be subject to grants
under the Equity Plan from 2,000,000 to 3,300,000 subject to adjustment for
stock splits, stock dividends and certain transactions affecting the Company's
capital stock.

                      GENZYME CORPORATION AND SUBSIDIARIES
         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.   Basis of Presentation:
     ---------------------

          These unaudited, condensed, consolidated financial statements should
     be read in conjunction with the Company's Annual Report on Form 10-K/A 
     for the fiscal year ended December 31, 1995 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 Securities and Exchange Commission
     rules and regulations. Certain items in the 1995 financial statements have
     been reclassified to conform with the 1996 presentation.

          The financial statements for the three and six months ended June 30,
     1996 and 1995 are unaudited but include, in the Company's opinion, all
     adjustments (consisting only of normally recurring accruals) necessary for
     a fair presentation of the results for the periods presented.

2.   Accounting Policies:
     -------------------

          The accounting policies underlying the quarterly financial statements
     are those set forth in Note A of the financial statements included in the
     Company's Annual Report on Form 10-K/A for the year ended December 31, 
     1995.

3.   Investments:
     -----------

          As of June 30, 1996, the Company's investment portfolio, consisting
     primarily of debt securities classified as available for sale, was adjusted
     to its market value. As a result, gross unrealized holding gains of
     approximately $14,000 and gross unrealized holding losses totaling
     approximately $1,300,000 were recorded in a separate component of
     Stockholders' equity.

          In April 1996, the Company recorded a realized gain of approximately
     $1,711,000 on the sale of its investment in NABI.

          As of June 30, 1996, the carrying values of the Company's investments
     in Aronex, Inc., Celtrix Pharmaceuticals, Inc. and Integramed America, Inc.
     (formerly IVF America, Inc.), included in Other Noncurrent Assets in the
     unaudited, condensed, consolidated balance sheets, were adjusted to their
     respective market values. Gross unrealized holding gains of approximately
     $4,788,000 were recorded in a separate component of Stockholders' Equity.

5.   Provision for Income Taxes:
     --------------------------

          The tax provision for the three and six months ended June 30, 1996

     income taxes, the Company's share of losses of subsidiaries which
     generate no current tax benefit, tax credits, taxes on foreign earnings
     and differences in tax bases due to acquisitions. The effective tax rate 
     was 41% and 39.5%, respectively, for the three and six months ended 
     June 30, 1996, slight increases over the corresponding periods in 1995.

                      GENZYME CORPORATION AND SUBSIDIARIES
           NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

 6.  Additional Investments in Unconsolidated Affiliate:
     --------------------------------------------------

          Pursuant to the terms of the Convertible Debt and Development Funding
     Agreement executed between Genzyme and Genzyme Transgenics Corporation
     ("GTC") in March 1996, GTC borrowed an additional $500,000 per month in
     April, May and June 1996 from Genzyme. On June 28, 1996, at GTC's request
     and in accordance with the Agreement, Genzyme converted $1.5 million plus
     accrued interest of approximately $23,000 into 193,321 shares of GTC
     Common Stock which increased Genzyme's interest in GTC to 48.1%.

          On July 31, 1996, GTC sold 3,000,000 shares of its Common Stock to the
     public for $4.00 per share. Genzyme purchased 900,000 shares in the
     offering after which Genzyme will own a 44.8% interest in GTC.

 7.  Allocation by the General Division to GTR for TR Designated Shares:
     ------------------------------------------------------------------

          In June 1996, pursuant to the terms of an option held by Genzyme to
     allocate up to $30 million from Genzyme General Division (the General
     Division) to Genzyme Tissue Repair Division ("GTR"), the Board of Directors
     voted to allocate $10 million of cash from the General Division to GTR in
     June 1996 in exchange for an increase in the TR Designated Shares of
     1,000,000 shares, which shares have been reserved for distribution at the
     discretion of the Board of Directors.

 8.  Short-Term Borrowing Arrangements:
     ---------------------------------

          Genzyme has an available line of credit with a commercial bank of $215
     million, which may be used by either the General Division or GTR.
     In March 1996, GTR utilized $8.0 million under this line of credit
     as temporary financing for the acquisition of certain land and
     buildings in Framingham, Massachusetts (the "Acquisition") that were
     purchased for $6.8 million in cash in January 1996 as part of the planned
     expansion of manufacturing capacity for the CARTICEL[Service Mark] Service
     programs. In May 1996, GTR repaid the entire $8.0 million borrowed plus
     accrued interest of approximately $65,000. In June 1996, GTR borrowed $15.0
     million under the same credit line at an interest rate of approximately
     6.06% to provide further interim financing for the Acquisition and related
     required renovations until a suitable permanent financing arrangement can
     be obtained.

 9.  Acquisition of Genetrix, Inc.:
     ------------------------------

          On April 30, 1996, the Company acquired Genetrix Inc., a privately 
     held genetic testing laboratory based in Phoenix, Arizona, in a tax-free
     exchange of General Division Stock. In the aggregate, approximately
     690,000 shares of General Division Stock valued at approximately $36.5
     million were issued. The acquisition was accounted for as a purchase. The
     excess of the purchase price over the fair market value of the net assets
     acquired, approximately $34.6 million, was allocated to Goodwill to be
     amortized over 15 years.

10.  Withdrawal of Offer to Acquire the Assets of Genzyme Development
     -----------------------------------------------------------------
     Partners, L.P.:
     ---------------
     
          On May 3, 1996, Genzyme announced that it was withdrawing its offer to
     acquire substantially all of the assets of Genzyme Development Partners,
     L.P. (the "Partnership") for shares of Genzyme General Division Common
     Stock valued at $93 million at the time the offer was made. The withdrawal
     of the offer by Genzyme does not affect the respective rights and
     obligations of the Partnership and Genzyme under any of the existing
     agreements between the parties. 

11.  Long-Term Debt:
     ---------------

          In March 1996, holders of the Company's 6 3/4% percent convertible
     subordinated notes in the principal amount of $100 million converted such
     notes into General Division and TR Stock. Holders of the notes received
     18.913 shares of General Division Stock and 2.553 shares of TR Stock in
     conversion of each $1,000 note. As a result of the conversion, the holders
     forfeited interest which would have been payable by the Company on April 1,
     1996. The carrying amount of the debt, net of unamortized discount, plus
     accrued interest of approximately $2,914,000 was credited to Stockholders'
     Equity.

12.  Subsequent Event:
     ----------------

          On July 1, 1996, Genzyme completed the acquisition of Deknatel Snowden
     Pencer, Inc. ("DSP"), a privately held surgical products company, for
     approximately $250.0 million. The purchase price consisted of cash of
     approximately $190.0 million. Genzyme also assumed and subsequently repaid
     debt of DSP of approximately $56.5 million, and Genzyme paid acquisition
     costs of approximately $3.5 million. Funds for the acquisition, the
     repayment of the debt and the payment of the acquisition costs were
     provided by borrowings of $200.0 million under a revolving credit facility
     from Fleet National Bank, due September 1, 1997, with interest payable at
     LIBOR plus 5/8% (6.16% at July 1, 1996) and approximately $50.0 million was
     provided from the Company's cash balances.

12.  Subsequent Event (continued):
     ----------------------------

          DSP designs, manufactures and markets cardiovascular devices,
     precision instruments and specialty surgical products. DSP had net sales of
     $95.3 million in the fiscal year ending September 30, 1995. Its 70-person
     sales force calls directly on cardiovascular, general and gynecological
     surgeons throughout the U.S. and Europe and has a strong presence in the
     operating rooms of major hospitals. Genzyme will retain DSP personnel and
     facilities and continue to pursue DSP's growth strategy.

          Genzyme plans to use DSP's sales force to accelerate the introduction
     of its Seprafilm[Trademark] bioresorbable membrane to the U.S.
     surgical market once Seprafilm[Trademark] is approved by the U.S. Food and
     Drug Administration.

          In June 1996, the Board of Directors declared a 2-for-1 stock split of
     shares of General Division Stock to be effected by means of a 100% stock
     dividend payable on July 25, 1996 to stockholders of record on July  11,
     1996, subject to increasing the authorized shares of General Division Stock
     from 100,000,000 to 200,000,000 shares (the "Amendment"). The Amendment was
     approved by holders of a majority in interest of the outstanding General
     Division and TR Stock, voting together as a single class, at a special
     meeting of the stockholders held on July 24, 1996. On July 25, 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. 

          In July 1996, the Company agreed to make a final payment of
     approximately $7.6 million for a company acquired in 1994. 

          On July 31, 1996, GTC sold 3,000,000 shares of its Common Stock to
     the public for $4.00 per share. Genzyme purchased 900,000 shares in the
     offering after which Genzyme will own a 44.8% interest in GTC.

          On August 13, 1996, the FDA granted approval to market Seprafilm
     [Registered Trademark] for use in any open abdominal or pelvic surgery. 
     There are estimated to be approximately 3.1 million such surgeries
     performed annually in the United States. Genzyme, on behalf of the Joint
     Venture formed between Genzyme and the Partnership, expects to launch
     Seprafilm[Registered Trademark] broadly in the United States in October,
     using the DSP sales force. Under the terms of the agreements between
     Genzyme and the Partnership, the Joint Venture will manufacture and market
     Seprafilm[Registered Trademark] in North America under contract with
     Genzyme.  Genzyme and the Partnership expect to conclude negotiations
     during the third quarter to establish definitive terms for the Joint
     Venture, including the allocation between the parties of profits and
     losses from the Joint Venture.

                            GENZYME GENERAL DIVISION
           NOTES TO UNAUDITED CONDENSED COMBINED FINANCIAL STATEMENTS

1.   Basis of Presentation:
     ---------------------

          These unaudited, condensed, combined financial statements should be
     read in conjunction with the Company's Annual Report on Form 10-K/A for 
     the fiscal year ended December 31, 1995 and the financial statements and 
     footnotes for Genzyme General Division 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 Securities and
     Exchange Commission rules and regulations. The financial statements for the
     three and six months ended June 30, 1996 and 1995 are unaudited but
     include, in the Division's opinion, all adjustments (consisting only of
     normally recurring accruals) necessary for a fair presentation of the
     results for the periods presented.

2.   Accounting Policies:
     -------------------

          The accounting policies underlying the quarterly financial statements
     are those set forth in Note A of the General Division's financial
     statements included in the Company's Annual Report on Form 10-K/A for the 
     year ended December 31, 1995.

3.   Investments:
     -----------

          As of June 30, 1996, the General Division's investment portfolio,
     consisting primarily of debt securities classified as available for sale,
     was adjusted to its market value. As a result, gross unrealized holding
     gains of approximately $14,000 and gross unrealized holding losses totaling
     approximately $1,293,000 were recorded in a separate component of Division
     equity.

          In April 1996, the General Division recorded a realized gain of
     approximately $1,711,000 on the sale of its investment in NABI.

          As of June 30, 1996, the carrying values of the General Division's
     investments in Aronex, Inc., Celtrix Pharmaceuticals, Inc. and Integramed
     America, Inc. (formerly IVF America, Inc.), included in Other Noncurrent
     Assets in the unaudited, condensed, combined balance sheets, were adjusted
     to their respective market values. Gross unrealized holding gains of
     approximately $4,788,000 were recorded in a separate component of Division
     equity.

5.   Provision for Income Taxes:
     --------------------------

          The tax provision for the three and six months ended June 30, 1996
     varies from the U.S. statutory tax rate because of the provision for state
     income taxes, the General Division's share of losses of subsidiaries which
     generate no current tax benefit, tax credits, taxes on foreign earnings 
     and differences in tax bases due to acquisitions. The effective tax rate 
     was 41% and 39.9% for the three and six months ended June 30, 1996, slight 
     increases over the corresponding periods in 1995. The allocated tax 
     benefit generated by GTR of $4.3 million and $2.0 million in the second 
     quarter of 1996 and 1995, respectively, reduced the General Division's tax 
     rate for those periods to 25.1% and 26.4%, respectively. For the six
     months  ended June 30, 1996 and 1995, the allocated tax benefit generated
     by GTR  of $7.8 million

5.   Provision for Income Taxes (continued):
     --------------------------------------

     and $3.7 million, respectively, reduced the General Division's tax rate for
     the respective six month periods to 25% and 27.3%.

6.   Additional Investments in Unconsolidated Affiliate:
     --------------------------------------------------

          Pursuant to the terms of the Convertible Debt and Development Funding
     Agreement executed between Genzyme and GTC in March 1996, GTC borrowed an 
     additional $500,000 per month in April, May and June 1996 from the General 
     Division. On June 28, 1996, at GTC's request, the General Division 
     converted $1.5 million plus accrued interest of approximately $23,000 into
     193,321  shares of GTC Common Stock which increased the General Division's
     interest  in GTC to 48.1%.

          On July 31, 1996, GTC sold 3,000,000 shares of its common stock to
     the public for $4.00 per share. Genzyme purchased 900,000 shares in the
     offering after which Genzyme will own a 44.8% interest in GTC.

7.   Allocation by the General Division to GTR for TR Designated Shares:
     ------------------------------------------------------------------

          In June 1996, pursuant to the terms of an option held by Genzyme to
     allocate up to $30 million from the General Division to GTR, the Board of
     Directors voted to allocate $10 million of cash from the General Division
     to GTR in exvchange for an increase in the TR Designated Shares of
     1,000,000 shares, which shares have been reserved for distribution at the
     discretion of the Board of Directors.  
          
8.   Acquisition of Genetrix, Inc.
     -----------------------------

          On April 30, 1996, the General Division acquired Genetrix, Inc., a
     privately held genetic testing laboratory based in Phoenix, Arizona, in a
     tax-free exchange of General Division Stock. In the aggregate,
     approximately 690,000 shares of General Division Stock valued at 
     approxmiately $36.5 million were issued. The acquisition was accounted for
     as a purchase. The excess of the purchase price over the fair market value
     of the net assets acquired, approximately $34.6 million, was allocated to
     Goodwill to be amortized over 15 years.

9.   Withdrawal of Offer to Acquire the Assets of 
     Genzyme Development Partners, L.P.:
     --------------------------------------------

          On May 3, 1996, Genzyme announced that it was withdrawing its offer
     to acquire substantially all of the assets of Genzyme Development
     Partners, L.P. (the "Partnership") for shares of Genzyme General Division
     Common Stock valued at $93 million at the time the offer was made. The
     withdrawal of the offer by Genzyme does not affect the respective rights
     and obligations of the Partnership and Genzyme under any of the existing
     agreements between the parties. 

10.  Long-Term Debt:
     --------------
          
          In March 1996, holders of the Company's 6 3/4% percent convertible
     subordinated notes in the principal amount of $100 million converted such
     notes into General Division and TR Stock. Holders of the notes received 
     18.913 shares of General Division Stock and 2.553 shares of TR Stock in 
     conversion of each $1,000 note. As a result of the conversion, the holders
     forfeited interest which would have been payable by the Company on 
     April 1, 1996. The carrying amount of the debt, net of unamortized
     discount, plus accrued interest of approximately $2,914,000 was credited
     to Stockholders' Equity.

11.  Subsequent Events:
     -----------------

          On July 1, 1996, the General Division completed the acquisition of 
     DSP, a privately held surgical products company, for approximately
     $250.0 million. The purchase price consisted of cash of approximately
     $190.0 million. The General Division also assumed and subsequently repaid 
     debt of DSP of approximately $56.5 million, and the General Division paid 
     acquisition costs of approximately $3.5 million. Funds for the 
     acquisition, the repayment of the debt and the payment of the acquisition 
     costs were provided by borrowings of $200.0 million under a revolving 
     credit facility from Fleet National Bank, due September 1, 1997, with 
     interest payable at LIBOR plus 5/8% (6.16% at July 1, 1996) and 
     approximately $50.0 million was provided from General Division cash 
     balances.
          
          DSP designs, manufactures and markets cardiovascular devices,
     precision instruments and specialty surgical products. DSP had net sales
     of $95.3 million in the fiscal year ending September 30, 1995. Its 
     70-person sales force calls directly on cardiovascular, general and 
     gynecological surgeons throughout the U.S. and Europe and has a strong 
     presence in the operating rooms of major hospitals. The General Division 
     will retain DSP personnel and facilities and continue to pursue DSP's 
     growth strategy.

          The General Division plans to use DSP's sales force to accelerate the 
     introduction of its Seprafilm[Registered Trademark] bioresorbable membrane 
     to the U.S. surgical market once Seprafilm[Trademark] is approved by the 
     U.S. Food and Drug Administration.

          In June 1996, the Board of Directors declared a 2-for-1 stock split
     of shares of General Division Stock to be effected by means of a 100%
     stock dividend payable on July 25, 1996 to stockholders of record on
     July 11, 1996, subject to increasing the authorized shares of General
     Division Stock from 100,000,000 to 200,000,000 shares (the "Amendment").
     The Amendment was approved by holders of a majority in interest of the
     outstanding General Division and TR Stock, voting together as a single
     class, at a special meeting of the stockholders held on July 24, 1996. 
     On July 25, 1996, a total 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.

          In July 1996, the General Division agreed to make a final payment of
     approximately $7.6 million for a company acquired in 1994. 

          On July 31, 1996, GTC sold 3,000,000 shares of its Common Stock to
     the public for $4.00 per share. Genzyme purchased 900,000 shares in the
     offering after which Genzyme will own a 44.8% interest in GTC.

          On August 13, 1996, the FDA granted approval to market Seprafilm
     [Registered Trademark] for use in any open abdominal or pelvic surgery. 
     There are estimated to be approximately 3.1 million such surgeries
     performed annually in the United States. Genzyme, on behalf of the Joint
     Venture formed between Genzyme and the Partnership, expects to launch
     Seprafilm[Registered Trademark] broadly in the United States in October,
     using the DSP sales force. Under the terms of the agreements between
     Genzyme and the Partnership, the Joint Venture will manufacture and market
     Seprafilm[Registered Trademark] in North America under contract with
     Genzyme. Genzyme and the Partnership expect to conclude negotiations
     during the third quarter to establish definitive terms for the Joint
     Venture, including the allocation between the parties of profits and
     losses from the Joint Venture.

                         GENZYME TISSUE REPAIR DIVISION
             NOTES TO UNAUDITED CONDENSED COMBINED FINANCIAL STATEMENTS

1.   Basis of Presentation:
     ---------------------

          These unaudited, condensed, combined financial statements should be
     read in conjunction with the Company's Annual Report on Form 10-K/A for 
     the fiscal year ended December 31, 1995 and the financial statements and 
     footnotes for GTR 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 Securities and Exchange Commission 
     rules and regulations.

          The financial statements for the three and six months ended June 30,
     1996 and 1995 are unaudited but include, in GTR's opinion, all adjustments
     (consisting only of normally recurring accruals) necessary for a fair
     presentation of the results for the periods presented.

2.   Accounting Policies:
     -------------------

          The accounting policies underlying the quarterly financial statements
     are those set forth in Note A of GTR's financial statements included in the
     Company's Annual Report on Form 10-K/A for the year ended December 31, 
     1995.

3.   Investments:
     -----------

          As of June 30, 1996, GTR's investment portfolio, consisting primarily
     of debt securities classified as available for sale, was adjusted to its
     market value. As a result, gross unrealized holding losses totaling
     approximately $7,000 were recorded in a separate component of Division
     equity.

</TABLE>

5.   Allocation by the General Division to GTR for TR Designated Shares:
     ------------------------------------------------------------------
          
          In June 1996, pursuant to the terms of an option held by Genzyme to
     allocate up to $30 million from Genzyme General Divisison (the General
     Division) to Genzyme Tissue Repair Division ("GTR"), the Board of Directors
     voted to allocate $10 million of cash from the General Division to GTR in
     June 1996 in exchange for an increase in the TR Designated Shares of 
     1,000,000 shares, which shares have been reserved for distribution at 
     the discretion of the Board of Directors.

6.   Short-Term Borrowing Arrangements:
     ---------------------------------

          Genzyme has an available line of credit with a commercial bank of $215
     million, which may be used by either the General or Tissue Repair Division.
     In March 1996, GTR utilized $8.0 million under this credit line as 
     temporary financing for the acquisition of certain land and buildings in 
     Framingham, Massachusetts (the "Acquisition") that were purchased for $6.8 
     million in cash in January 1996 as part of the planned expansion of 
     manufacturing capacity for the CARTICEL[Service Mark] Service programs. In 
     May 1996, GTR repaid the entire $8.0 million borrowed plus accrued 
     interest of approximately $65,000. In June 1996, GTR borrowed $15.0 
     million under the same credit line at an interest rate of approximately
     6.06% to provide further interim financing for the Acquisition and related
     required renovations until a suitable permanent financing arrangement can
     be obtained.

                      GENZYME CORPORATION AND SUBSIDIARIES
               UNAUDITED CONDENSED PRO FORMA FINANCIAL STATEMENTS


INTRODUCTION:

     These unaudited condensed pro forma financial statements and the related
notes are presented to give effect to the acquisition (the "Genetrix
Acquisition") of Genetrix, Inc. ("Genetrix") with and into Genzyme Corporation
("Genzyme") using shares of the common stock of the Genzyme General Division
(the "General Division")(as described in Note 2), the acquisition (the "DSP
Acquisition") of the assets of Deknatel Snowden Pencer, Inc. ("DSP") by Genzyme
(as described in Note 3) and the probable acquisition of Neozyme II with and
into Genzyme (the "Neozyme II Acquisition") (as described in Note 4). Pro forma
condensed statements of operations have been presented for both Genzyme and the
General Division assuming that the Genetrix, DSP and Neozyme II acquisitions
each occurred as of January 1, 1995, using the purchase accounting method. Pro
forma balance sheets have been presented for both Genzyme and the General
Division assuming that the DSP Acquisition and the Neozyme II Acquisition
occurred as of June 30, 1996. The historical Genzyme Corporation and Genzyme
General Division results included in the pro forma balance sheets reflect the
effect of the Genetrix Acquisition which was completed on May 1, 1996. To
distinguish the effect of each transaction, subtotal columns have been included
on each financial statement to give effect to the Genetrix Acquisition, after
certain pro forma adjustments, and the DSP Acquisition, after certain pro forma
adjustments, before consideration of the Neozyme II Acquisition and any related
pro forma adjustments. The notes to the unaudited pro forma financial statements
are defined as related either to the Genetrix Acquisition, the DSP Acquisition
or the Neozyme II Acquisition.

     Year end for Genzyme, Genetrix and Neozyme II is December 31, while year
end for DSP prior to the acquisition by Genzyme was September 30. The pro forma
financial statements for the year ended December 31, 1995, herein, are based on
the historical income statements of Genzyme, Genetrix, and Neozyme II for the
year ended December 31, 1995 and the historical income statement for DSP for the
year ended September 30, 1995. Revenues and operating costs and expenses for DSP
for the three months ended December 31, 1995 were $22,001,000 and $18,260,000,
respectively.

the acquisition.
 
4.  GENZYME CORPORATION'S PROBABLE ACQUISITION OF NEOZYME II CORP.:
 
     On September 23, 1996, Genzyme announced that it has signed a definitive
acquisition agreement with Neozyme II Corp. under which Genzyme will commence a
tender offer for all outstanding units of Neozyme II at $45 per unit in cash.
Each Neozyme II unit consists of one share of Neozyme II callable common stock
and one callable warrant to purchase two shares of Genzyme General Division
Stock and 0.135 share of GTR Stock. The total purchase price of $108,675,000
plus estimated acquisition costs of $1 million has been allocated to acquired
cash and short-term investments of $13,848,000, prepaid research and
development of $527,000 which offsets Deferred Revenue recorded by Genzyme,
assumed liabilites of $258,000, $129,000 of which offsets a note receivable and
the interest related there to recorded by Genzyme and a charge for in-process
technology of $94,558,000.

                      GENZYME CORPORATION AND SUBSIDIARIES

  NOTES TO UNAUDITED CONDENSED PRO FORMA FINANCIAL STATEMENTS -- (CONTINUED)
 
     Under the agreement, if the tender offer is successfully completed, a
second-step transaction will be effected in which the Neozyme II unit-holders
who had not tendered their units will be entitled to receive $29 in cash for
each share of callable common stock included in the untendered units. The
callable warrants that had been included in the units acquired in the
second-step transaction will remain outstanding.
 
     Genzyme's obligation to purchase units in the tender offer will be subject
to the satisfaction of certain conditions, including the minimum condition of
the tender of at least a majority of the outstanding units. If less than a
majority of the outstanding units is tendered, Genzyme has the right under
certain circumstances to terminate the tender offer and seek the approval of the
holders of the units for the second-step transaction. Alternatively, Genzyme has
the right under certain circumstances, if a majority approves the second-step
transaction through a combination of shares of callable common stock included in
units tendered and untendered shares voting in favor of the transaction, to
waive the minimum condition and accept the tendered units.
 
    The pro forma financial statements assume that the full 2,415,000 callable
common shares of Neozyme II are purchased under the tender offer. The pro forma
adjustments to the pro forma statements of operations do not give effect to the
charge for in-process technology in the amount of $95,558,000 which is
expected to be charged to operations upon consummation of the acquisition.
