                                   ARTICLE IV

         If more than one class of stock is authorized, state a distinguishing
designation for each class. Prior to the issuance of any shares of a class, if
shares of another class are outstanding, the corporation must provide a
description of the preferences, voting powers, qualifications, and special or
relative rights or privileges of that class and of each other class of which
shares are outstanding and of each series then established within any class.


                          DESCRIPTION OF CAPITAL STOCK

A.       AUTHORIZED CAPITAL STOCK

         The total number of shares of all classes of capital stock which the
Corporation shall be authorized to issue is four hundred million (400,000,000)
shares, consisting of three hundred ninety million (390,000,000) shares of
Common Stock, $.01 par value per share (the "Common Stock") and ten million
(10,000,000) shares of Preferred Stock, $.01 par value per share (the "Preferred
Stock").

B.       UNDESIGNATED COMMON STOCK

         Shares of Common Stock not at the time designated as shares of a
particular series pursuant to this Section IV.B. or any other provision of these
Articles of Organization may be issued from time to time in one or more
additional 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,
provided that in no event shall the holder of a share of any series of Common
Stock be entitled to more than one vote per share at the time that shares of
such series are first issued. The Board of Directors shall determine the number
of shares constituting each series of Common Stock and each series shall have a
distinguishing designation.

C.       GENZYME GENERAL DIVISION COMMON STOCK

         1. AUTHORIZED AMOUNTS. Two hundred million (200,000,000) shares of
Common Stock are designated as a series of Common Stock with the following
designation: Genzyme General Division Common Stock (the "GGD Stock"). To the
extent legally permitted, such number of shares may be increased or decreased by
vote of the Board of Directors, provided that no decrease shall reduce the
number of shares of GGD Stock to a number less than the number of shares of such
series then outstanding plus the number of shares of such series reserved for
issuance upon the exercise of outstanding options, rights or warrants or upon
the conversion of any outstanding securities issued by the Corporation
convertible into such series of Common Stock. A description of the GGD Stock and
a statement of its preferences, voting powers, qualifications and special or
relative rights or privileges is as follows:

         2. DIVIDENDS AND DISTRIBUTIONS. Subject to the express terms of any
outstanding series of Preferred Stock, dividends may be declared and paid upon
the GGD Stock, in such amounts and at such times as the Board of Directors may
determine, only out of the lesser of (a) funds of the Corporation legally
available therefor and (b) the Available GGD Dividend Amount.

         3. VOTING RIGHTS. The holders of GGD Stock, voting together with the
holders of shares of all other series of Common Stock as a single class of
stock, shall have the exclusive right to vote for the election of directors and
on all other matters requiring action by the stockholders or submitted to the
stockholders for action, except as may be determined by the Board of Directors
in establishing any series of Common or Preferred Stock or as may otherwise be
required by law. Each share of the GGD Stock shall entitle the holder thereof to
one vote.


                                       3
<PAGE>

         4. LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any voluntary or
involuntary liquidation, dissolution or winding up of the Corporation, the
rights of the holders of GGD Stock shall be as follows:

                  (a) After the Corporation has satisfied or made provision for
its debts and obligations and for the payment to the holders of shares of any
class or series of capital stock having preferential rights to receive
distributions of the net assets of the Corporation (including any accumulated
and unpaid dividends), the holders of GGD Stock shall be entitled to receive the
net assets of the Corporation remaining for distribution, on a per share basis
in proportion to the respective liquidation units per share of all series of
Common Stock. Each share of GGD Stock shall have one hundred (100) liquidation
units.

                  (b) For the purposes of Section IV.C.4(a), any merger or
business combination involving the Corporation or any sale of all or
substantially all of the assets of the Corporation shall not be treated as a
liquidation.

         5. SPECIAL VOTING RIGHTS. The Corporation shall not, without approval
by the holders of the GGD Stock at a meeting at which a quorum is present and
the votes cast in favor of the proposal exceed those cast against:

                  (a) allow any proceeds from the Disposition of the properties
or assets allocated to Genzyme General Division to be used in the business of
any other Division without fair compensation being allocated to Genzyme General
Division as determined by the Board of Directors;

                  (b) allow any properties or assets allocated to Genzyme
General Division to be used in the business of any other Division or for the
declaration or payment of any dividend or distribution on any series of Common
Stock other than the GGD Stock without fair compensation being allocated to
Genzyme General Division as determined by the Board of Directors;

                  (c) issue, sell or otherwise distribute shares of GGD Stock
without allocating the proceeds or other benefits of such issuance, sale or
distribution to Genzyme General Division;

                  (d) change the rights or preferences of the GGD Stock so as to
affect the GGD Stock adversely; or

                  (e) effect any merger or business combination involving the
Corporation as a result of which (a) the holders of all series of Common Stock
of the Corporation shall no longer own, directly or indirectly, at least fifty
percent (50%) of the voting power of the surviving corporation and (b) the
holders of all series of Common Stock of the Corporation do not receive the same
form of consideration, distributed among such holders in proportion to the
Market Capitalization of each series of Common Stock as of the date of the first
public announcement of such merger or business combination.

         6. DEFINITIONS. As used in this Section IV.C., the following terms
shall have the following meanings (with terms defined in the singular having
comparable meaning when used


                                       4
<PAGE>

in the plural and vice versa), unless another definition is provided or the
context otherwise requires:

         (a) "Available GGD Dividend Amount," on any date, shall mean the
greater of:

                  (1) the excess of

                           (A) the greater of (x) the fair value on such date of
the net assets of Genzyme General Division and (y) an amount equal to
$335,378,000 (stockholders' equity allocated to Genzyme General Division at June
30, 1994), such dollar amount to be increased or decreased, as appropriate, to
reflect, after June 30, 1994, (A) the Earnings Attributable to Genzyme General
Division, (B) any dividends or other distributions (including by
reclassification or exchange) declared or paid with respect to, or repurchases
or issuances of, any shares of GGD Stock or any other class of capital stock
attributed to Genzyme General Division, but excluding dividends or other
distributions paid in shares of GGD Stock to the holders thereof or in shares of
any other class of capital stock attributed to Genzyme General Division to the
holders thereof, and (C) any other adjustments to the stockholders' equity of
Genzyme General Division made in accordance with generally accepted accounting
principles, over

                           (B) the sum of (x) the aggregate par value of all
outstanding shares of GGD Stock and any other class of capital stock attributed
to Genzyme General Division and (y) unless these Articles of Organization permit
otherwise, the aggregate amount that would be needed to satisfy any preferential
rights to which holders of all outstanding Preferred Stock attributed to Genzyme
General Division are entitled upon dissolution of the Corporation in excess of
the aggregate par value of such Preferred Stock, provided that such excess shall
be reduced by any amount necessary to enable Genzyme General Division to pay its
debts as they become due, and

                  (2) the amount legally available for the payment of dividends
determined in accordance with Massachusetts law applied as if Genzyme General
Division were a separate corporation.

         (b) "Earnings Attributable" to Genzyme General Division for any period,
shall mean the net income or loss of Genzyme General Division for such period
(or for the fiscal periods of the Corporation commencing prior to the GTR
Effective Date and after June 30, 1994, pro forma net income or loss of Genzyme
General Division as if the GTR Effective Date were June 30, 1994) determined in
accordance with generally accepted accounting principles, with all income and
expenses of the Corporation being allocated between Divisions in a reasonable
and consistent manner in accordance with policies adopted by the Board of
Directors; provided, however, that as of the end of any fiscal quarter of the
Corporation, any projected annual tax benefit attributable to any Division that
cannot be utilized by such Division to offset or reduce its allocated tax
liability may be allocated to any other Division without any compensating
payment or allocation.

         (c) "Genzyme General Division" shall mean, at any time, the
Corporation's interest in (i) all of the businesses, products, or development or
research programs in which the Corporation or any of its subsidiaries (or any of
their predecessors or successors) is or has been


                                       5
<PAGE>

engaged, directly or indirectly, other than those allocated to any division of
the Corporation represented by a series of Common Stock (any "Division") other
than the GGD Stock; and (ii) all assets and liabilities of the Corporation to
the extent allocated to any such businesses, products, or development or
research programs in accordance with generally accepted accounting principles
consistently applied for all of the Corporation's business units. From and after
the date on which all of the outstanding shares of any series of Common Stock
are exchanged for shares of GGD Stock, other securities, cash, other property or
a combination thereof, all of the businesses, products, development or research
programs, assets and liabilities of the Division represented by such series of
Common Stock shall be included in Genzyme General Division. Genzyme General
Division shall be represented by the GGD Stock.

D.       GENZYME MOLECULAR ONCOLOGY COMMON STOCK

         1. AUTHORIZED AMOUNTS AND DESIGNATIONS. Forty million (40,000,000)
shares of Common Stock are designated as a series of Common Stock with the
following designation: Genzyme Molecular Oncology Division Common Stock (the
"GMO Stock"). To the extent legally permitted, such number of shares may be
increased or decreased by vote of the Board of Directors, provided that no
decrease shall reduce the number of shares of GMO Stock to a number less than
the number of shares of such series then outstanding plus the number of shares
of such series reserved for issuance upon the exercise of outstanding options,
rights or warrants or upon the conversion of any outstanding securities issued
by the Corporation convertible into such series of Common Stock.

         2. DIVIDENDS AND DISTRIBUTIONS. Subject to the express terms of any
outstanding series of Preferred Stock, dividends may be declared and paid upon
the GMO Stock, in such amounts and at such times as the Board of Directors may
determine, only out of the lesser of (a) funds of the Corporation legally
available therefor and (b) the Available GMO Dividend Amount.

         3. VOTING RIGHTS. The holders of GMO Stock, voting together with the
holders of shares of all other series of Common Stock as a single class of
stock, shall have the exclusive right to vote for the election of directors and
on all other matters requiring action by the stockholders or submitted to the
stockholders for action, except as may be determined by the Board of Directors
in establishing any series of Common or Preferred Stock or as may otherwise be
required by law. Each share of GMO Stock shall entitle the holder thereof to .08
vote through December 31, 2000. On January 1, 2001 and on each January 1 every
two years thereafter, the number of votes to which the holder of each share of
GMO Stock shall be entitled shall be adjusted and fixed for two-year periods to
equal the quotient (expressed as a decimal and rounded to the nearest two
decimal places) obtained by dividing (i) the Fair Market Value of one share of
GMO Stock by (ii) Fair Market Value of one share of GGD Stock as of such date.
If no shares of GGD Stock are outstanding on such date, then all other series of
voting Common Stock outstanding on such date shall have a number of votes such
that each share of the series of outstanding Common Stock that has the highest
Fair Market Value per share on such date (the "Base Series") shall have one vote
and each share of each other series of outstanding Common Stock shall have the
number of votes determined according to the immediately preceding sentence,
treating, for such purpose, the Base Series as the GGD Stock in such sentence.
If shares of GMO Stock are entitled to vote separately as a class, each share of
GMO Stock shall have one vote.


                                       6
<PAGE>

         4. LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any voluntary or
involuntary liquidation, dissolution or winding up of the Corporation, the
rights of the holders of GMO Stock shall be as follows:

                  (a) After the Corporation has satisfied or made provision for
its debts and obligations and for the payment to the holders of shares of any
class or series of capital stock having preferential rights to receive
distributions of the net assets of the Corporation (including any accumulated
and unpaid dividends), the holders of GMO Stock shall be entitled to receive the
net assets of the Corporation remaining for distribution, on a per share basis
in proportion to the respective liquidation units per share of all series of
Common Stock. Each share of GMO Stock shall, subject to Section IV.G.4., have 25
liquidation units.

                  (b) For the purposes of Section IV.D.4(a) any merger or
business combination involving the Corporation or any sale of all or
substantially all of the assets of the Corporation shall not be treated as a
liquidation.

         5. SPECIAL VOTING RIGHTS. The Corporation shall not, without approval
by the holders of the GMO Stock at a meeting at which a quorum is present and
the votes cast in favor of the proposal exceed those cast against:

                  (a) allow any proceeds from the Disposition of the properties
or assets allocated to Genzyme Molecular Oncology Division to be used in the
business of any other Division without fair compensation being allocated to
Genzyme Molecular Oncology Division as determined by the Board of Directors;

                  (b) allow any properties or assets allocated to Genzyme
Molecular Oncology Division to be used in the business of any other Division or
for the declaration or payment of any dividend or distribution on any series of
Common Stock other than the GMO Stock without fair compensation being allocated
to Genzyme Molecular Oncology Division as determined by the Board of Directors;

                  (c) issue, sell or otherwise distribute shares of GMO Stock
without allocating the proceeds or other benefits of such issuance, sale or
distribution to Genzyme Molecular Oncology Division; provided, however, that the
Corporation may without such approval issue GMO Designated Shares;

                  (d) change the rights or preferences of the GMO Stock so as to
affect the GMO Stock adversely; or

                  (e) effect any merger or business combination involving the
Corporation as a result of which (i) the holders of all series of Common Stock
of the Corporation shall no longer own, directly or indirectly, at least fifty
percent (50%) of the voting power of the surviving corporation and (ii) the
holders of all series of Common Stock of the Corporation do not receive the same
form of consideration, distributed among such holders in proportion to the
Market Capitalization of each series of Common Stock as of the date of the first
public announcement of such merger or business combination.


                                       7
<PAGE>

         Notwithstanding the foregoing, if the Corporation receives an opinion
of Qualified Tax Counsel that, by reason of any Tax Law Change, the special
voting rights of the GMO Stock set forth in this subsection 5 would cause a Tax
Event absent the termination of such rights, then the Corporation may, by vote
of a majority of the stock outstanding and entitled to vote thereon, voting
together as a single class, authorize an amendment to these Articles of
Organization to effect the termination of such rights in order to avoid the
occurrence of such Tax Event. Any such amendment shall not be deemed to change
the rights or preferences of the GMO Stock so as to affect the GMO Stock
adversely as contemplated by either Section IV.D.5(d) or Section 77 of the
Massachusetts Business Corporation Law.

         6. EXCHANGE OR REDEMPTION OF GMO STOCK. Shares of GMO Stock are subject
to exchange or redemption upon the terms and conditions set forth below:

                  (a) OPTIONAL EXCHANGE OF GMO STOCK.

                           (1) The Board of Directors may at any time, including
without limitation in the event of the reallocation, in one transaction or a
series of related transactions, by the Corporation and/or its subsidiaries of
all or substantially all of the properties and assets allocated to Genzyme
Molecular Oncology Division to any other Division of Genzyme, declare that each
of the outstanding shares of GMO Stock shall be exchanged, on an Exchange Date,
as determined by the Board of Directors, for (a) a number of fully paid and
nonassessable shares of GGD Stock (calculated to the nearest five decimal
places) equal to (1) 130% of the Fair Market Value of one share of the GMO Stock
(the "GMO Optional Exchange Amount") as of the date of the first public
announcement by the Corporation (the "GMO Optional Exchange Announcement Date")
of such exchange divided by (2) the Fair Market Value of one share of GGD Stock
as of such GMO Optional Exchange Announcement Date or (b) cash equal to the GMO
Optional Exchange Amount, or (c) any combination of GGD Stock and cash equal to
the GMO Optional Exchange Amount as determined by the Board of Directors.

                           (2) If the Corporation receives an opinion of
Qualified Tax Counsel that a Tax Event has occurred by reason of any Tax Law
Change, then the Board of Directors may at any time declare that each of the
outstanding shares of GMO Stock shall be exchanged, on an Exchange Date, as
determined by the Board of Directors, for a number of fully paid and
nonassessable shares of GGD Stock (calculated to the nearest five decimal
places) equal to (1) the Fair Market Value of one share of the GMO Stock as of
the date of the first public announcement by the Corporation of such exchange
divided by (2) the Fair Market Value of one share of GGD Stock as of such date.

                           (3) At any time at which all of the assets and
liabilities attributed to Genzyme Molecular Oncology Division (and no other
assets or liabilities of the Corporation or any subsidiary thereof) are held
directly or indirectly by one or more wholly-owned subsidiaries of the
Corporation (each, a "GMO Subsidiary"), the Board of Directors may, provided
that there are funds of the Corporation legally available therefor, exchange on
an Exchange Date, as determined by the Board of Directors, all of the
outstanding shares of GMO Stock for that number of the shares of common stock of
each GMO Subsidiary equal to the number of such GMO Subsidiary shares
outstanding immediately prior to such exchange multiplied by the GMO Allocation
Ratio, such shares of common stock of each GMO Subsidiary to be delivered to the


                                       8
<PAGE>

holders of shares of GMO Stock on the Exchange Date either directly or
indirectly through the delivery of shares of another GMO Subsidiary that owns
directly or indirectly all such shares, and to be divided among the holders of
GMO Stock on a pro rata basis in accordance with the number of shares of GMO
Stock held by each such holder, each of which shares of common stock of such GMO
Subsidiary shall be, upon such delivery, fully paid and nonassessable; PROVIDED,
HOWEVER, that upon any such exchange, any existing GMO Designated Shares shall
be cancelled in exchange for the allocation to Genzyme General of the direct or
indirect interest of the Corporation in any remaining outstanding shares of each
such GMO Subsidiary that are not transferred to the holders of GMO Stock in such
exchange.

         (b) MANDATORY EXCHANGE OR REDEMPTION OF OR PAYMENT OF DIVIDEND ON GMO
STOCK.

                  (1) GMO MANDATORY PAYMENT. In the event of the Disposition, in
one transaction or a series of related transactions, by the Corporation and/or
its subsidiaries of all or substantially all of the properties and assets
allocated to Genzyme Molecular Oncology Division to any person, entity or group
(other than a Disposition of a type set forth in subsection (2) of this
subsection (b)), on or prior to the 60th Business Day, or such earlier date
required under this Section IV.D.6, following the date of the GMO Mandatory
Payment Announcement (as defined in Section IV.D.6(d)(2)), the Corporation shall
select one of the following alternatives, as determined by the Board of
Directors in its discretion: (A) provided that there are funds of the
Corporation legally available therefor, pay to the holders of the shares of GMO
Stock a dividend on a pro rata basis in accordance with the number of shares of
GMO Stock held by each such holder in cash, securities (other than shares of a
series of Common Stock) and/or other property having a Fair Market Value as of
the date of the Disposition in the aggregate equal to the Fair Market Value as
of the date of the Disposition of the GMO Net Proceeds of such Disposition; or

                           (B) provided that there are funds of the Corporation
legally available therefor,

                                    (i) if such Disposition involves all (not
merely substantially all) of the properties and assets attributed to Genzyme
Molecular Oncology Division, redeem or exchange as of a Redemption Date
determined by the Board of Directors, all outstanding shares of GMO Stock in
exchange for, on a pro rata basis, cash, securities (other than shares of a
series of Common Stock) and/or other property having a Fair Market Value as of
the date of the Disposition in the aggregate equal to the Fair Market Value as
of the date of the Disposition of the GMO Net Proceeds of such Disposition; or

                                    (ii) if such Disposition involves
substantially all (but not all) of the properties and assets attributed to
Genzyme Molecular Oncology Division, redeem or exchange as of a Redemption Date
as determined by the Board of Directors such number of whole shares of GMO Stock
(which may be all, but not more than all, of such shares outstanding) as have in
the aggregate an average Closing Price during the period of ten (10) consecutive
Business Days beginning on the first Business Day immediately following the date
of the Estimated GMO Net Proceeds Announcement (as defined in Section
IV.D.6(d)(2)) closest


                                       9
<PAGE>

to the Fair Market Value as of the date of the Disposition of the GMO Net
Proceeds of such Disposition in consideration for, on a pro rata basis, cash
securities (other than shares of a series of Common Stock) and/or other property
having a Fair Market Value as of the date of the Disposition in the aggregate
equal to such Fair Market Value of the GMO Net Proceeds; or

                           (C) declare that each outstanding share of GMO Stock
shall be exchanged as of an Exchange Date as determined by the Board of
Directors into a number of fully paid and nonassessable shares of GGD Stock
equal to 110% of the ratio (calculated to the nearest five decimal places) of
the average Closing Price of one share of GMO Stock over the period of ten (10)
consecutive Business Days beginning on the first Business Day immediately
following the date of the Estimated GMO Net Proceeds Announcement (as defined in
Section IV.D.6(d)(2)) to the average Closing Price of one share of GGD Stock
over the same ten Business Day period.

Any redemption or exchange of or dividend payment on GMO Stock made pursuant to
this Section IV.D.6(b)(1) or Section IV.D.6(c)(3) is hereinafter referred to as
a "GMO Mandatory Payment." Notwithstanding the foregoing provisions of this
Section IV.D.6.(b), the Corporation shall redeem GMO Stock as provided by
Section IV.D.(b)(1)(B) only if the amount to be paid pursuant to such redemption
is less than or equal to the Available GMO Dividend Amount as of the Redemption
Date.

                  (2) EXCEPTIONS TO MANDATORY PAYMENT. Notwithstanding the
foregoing Section IV.D.6(b)(1) or Section IV.D.6(c)(3), a GMO Mandatory Payment
shall not be required by the occurrence of a Disposition:

                           (A) by the Corporation of all or substantially all of
the Corporation's properties and assets in one transaction or a series of
related transactions, including such Disposition in connection with the
dissolution, liquidation or winding up of the Corporation and the distribution
of assets to stockholders as referred to in Section IV.D.4;

                           (B) of the properties and assets attributed to
Genzyme Molecular Oncology Division as contemplated by Section IV.D.6(a)(3) or
otherwise to all holders of GMO Stock divided among such holders on a pro rata
basis in accordance with the number of shares GMO Stock outstanding;

                           (C) to any person or entity controlled (as determined
by the Board of Directors) by the Corporation;

                           (D) in connection with a Related Business Transaction
in respect of Genzyme Molecular Oncology Division; or

                           (E) that is conditioned upon the affirmative vote of
the holders of GMO Stock, voting as a separate class.

         (c) TERMINATION OF CASH EXCHANGE RIGHT. If the Corporation receives an
opinion of Qualified Tax Counsel that, by reason of any Tax Law Change, the
right or obligation of the Corporation to exchange GMO Stock for cash,
securities or other property pursuant to Section IV.D.6(a)(1) or (3) or
IV.D.6(b) (each, a "GMO Cash Exchange Right") would cause a Tax


                                       10
<PAGE>

Event if not terminated, then the Board of Directors may at any time, by a vote
of a majority of the directors then in office, elect to terminate any or all
such GMO Cash Exchange Rights, with the result that the Corporation shall
thereafter have, depending on which GMO Cash Exchange Right(s) is (are) so
terminated:

                  (1) under Section IV.D.6(a)(1) only the right to cause the
exchange of GMO Stock for GGD Stock and not for cash, securities or other
property other than capital stock of the Corporation,

                  (2) no right to effect an exchange under Section IV.D.6(a)(3),
and/or

                  (3) no right or obligation to effect a GMO Mandatory Payment
under Section IV.D.6(b), provided that if the Board shall no longer have the
right or obligation to effect a GMO Mandatory Payment under Section IV.D.6(b),
then if a GMO Mandatory Payment thereunder shall otherwise be or have been
required, the Corporation instead shall have the obligation to effect on or
prior to the first Business Day after the 90th day following the consummation of
such Disposition, a GMO Mandatory Payment pursuant to which it shall exchange
each outstanding share of GMO Stock for a number of fully paid and nonassessable
shares of GGD Stock (calculated to the nearest five decimal places) equal to (i)
the Fair Market Value of one share of the GMO Stock as of the date of the first
public announcement of such Disposition by the Corporation by press release
divided by (ii) the Fair Market Value of one share of GGD Stock as of such date.

         Notwithstanding the foregoing, the Board of Directors may not terminate
any GMO Cash Exchange Right during the period commencing on the date of a
Disposition requiring a GMO Mandatory Payment until the date upon which the
related Mandatory Payment is effected by the Corporation.

         (d) EXCHANGE AND REDEMPTION PROCEDURES.

                  (1) If the Corporation determines to exchange shares of GMO

preceding sentence, such notice shall conform with the provisions governing
notice at Section IV.G.1 and the provisions governing the payment of such
dividend shall be those set for in such Section IV.G.1 to the extent such
provisions are applicable to the payment of a dividend.

                  (4) If the Corporation determines to redeem shares of GMO
Stock pursuant to Section IV.D.6(b)(1)(B)(i), the Corporation shall, not later

                  (2) in the case of a Disposition of properties and assets in a
series of related transactions, such Disposition shall not be deemed to have
been consummated until the consummation of the last of such transactions; and

                  (3) in the event that at the time of any Disposition there are
outstanding any Convertible Securities convertible into or exercisable for
shares of GMO Stock that would give the holders rights to receive any dividend
related to the Disposition upon exercise, conversion or otherwise, or would
adjust as a result of such dividend to give the holder equivalent economic
rights, then the shares of GMO Stock underlying such Convertible Securities will
be taken into account for purposes of computing the GMO Allocation Ratio and
determining the terms of any dividend payment on such shares;

                  (4) in the event that as a result of or in connection with a

Equity Line by (ii) the dollar amount determined for each such advance by the
following formula: 7.00 + [(IPOGMO - 7.00) x (ADATE/IPODATE)]; where IPOGMO =
the offering price of the GMO Stock in the first such public offering, ADATE =
the number of days from the GMO Effective Date to the time of such advance, and
IPODATE = the number of days from the GMO Effective Date to the time of the
first such public offering; and, thereafter, upon each advance made under the
Equity Line, a number equal to the quotient obtained by dividing (i) the amount

reasonable provision for, (a) any taxes payable by the Corporation in respect of
either such Disposition or any mandatory exchange, redemption or dividend
payment resulting from such Disposition (or that would have been payable but for
the utilization of tax benefits attributable to any division or group of the

E.       GENZYME SURGICAL PRODUCTS DIVISION COMMON STOCK

         1. AUTHORIZED AMOUNTS AND DESIGNATIONS. Sixty million (60,000,000)
shares of Common Stock are designated as a series of Common Stock with the
following designation: Genzyme Surgical Products Division Common Stock (the "GSP
Stock"). To the extent legally permitted, such number of shares may be increased
or decreased by vote of the Board of Directors, PROVIDED that no decrease shall
reduce the number of shares of GSP Stock to a number less than the number of
shares of such series then outstanding plus the number of shares of such series
reserved for issuance upon the exercise of outstanding options, rights or
warrants or upon the conversion of any outstanding securities issued by the
Corporation convertible into GSP Stock.

         2. DIVIDENDS AND DISTRIBUTIONS. Subject to the express terms of any
outstanding series of Preferred Stock, dividends may be declared and paid upon
the GSP Stock, in such amounts and at such times as the Board of Directors may
determine, only out of the lesser of (a) funds of the Corporation legally
available therefor and (b) the Available GSP Dividend Amount.

         3. VOTING RIGHTS. The holders of GSP Stock, voting together with the
holders of shares of all other series of Common Stock as a single class of
stock, shall have the exclusive right to vote for the election of directors and
on all other matters requiring action by the stockholders or submitted to the
stockholders for action, except as may be determined by the Board of Directors
in establishing any series of Common or Preferred Stock or as may otherwise be
required by law. Each share of GSP Stock shall entitle the holder thereof to .61
vote through December 31, 2000. On January 1, 2001 and on each January 1 every
two years thereafter, the number of votes to which the holder of each share of
GSP Stock shall be entitled shall be adjusted and fixed for two-year periods to
equal the quotient (expressed as a decimal and rounded to the nearest two
decimal places) obtained by dividing (i) the Fair Market Value of one share of
GSP Stock by (ii) the Fair Market Value of one share of GGD Stock as of such
date. If no shares of GGD Stock are outstanding on such date, then all other
series of voting Common Stock outstanding on such date shall have a number of
votes such that each share of the series of outstanding Common Stock that has
the highest Fair Market Value per share on such date (the "Base Series") shall
have one vote and each share of each other series of outstanding Common Stock
shall have the number of votes determined according to the immediately preceding
sentence, treating, for such purpose, the Base Series as the GGD Stock in such
sentence. If shares of GSP Stock are entitled to vote separately as a class,
each share of GSP Stock shall have one vote.

         4. LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any voluntary or
involuntary liquidation, dissolution or winding up of the Corporation, the
rights of the holders of GSP Stock shall be as follows:

                  (a) After the Corporation has satisfied or made provision for
its debts and obligations and for the payment to the holders of shares of any
class or series of capital stock having preferential rights to receive
distributions of the net assets of the Corporation (including any accumulated
and unpaid dividends), the holders of GSP Stock shall be entitled to receive the
net assets of the Corporation remaining for distribution, on a per share basis
in proportion to the respective liquidation units per share of all series of
Common Stock. Each share of GSP Stock shall, subject to this Section IV.E.4(a),
have 61 liquidation units.

                  (b) For the purposes of Section IV.E.4(a). any merger or
business combination involving the Corporation or any sale of all or
substantially all of the assets of the Corporation shall not be treated as a
liquidation.

         5. SPECIAL VOTING RIGHTS. The Corporation shall not, without approval
by the holders of the GSP Stock at a meeting at which a quorum is present and
the votes cast in favor of the proposal exceed those cast against:

                  (a) allow any proceeds from the Disposition of the properties
or assets allocated to Genzyme Surgical Products Division to be used in the
business of any other Division without fair compensation being allocated to

                  (c) issue, sell or otherwise distribute shares of GSP Stock

         Notwithstanding the foregoing, if the Corporation receives an opinion
of Qualified Tax Counsel that, by reason of any Tax Law Change, the special
voting rights of the GSP Stock set forth in this subsection 5 would cause a Tax
Event absent the termination of such rights, then the Corporation may, by vote
of a majority of the stock outstanding and entitled to vote thereon, voting
together as a single class, authorize an amendment to these Articles of
Organization to effect the termination of such rights in order to avoid the
occurrence of such Tax Event. Any such amendment shall not be deemed to change
the rights or preferences of the GSP Stock so as to affect the GSP Stock
adversely as contemplated by either Section IV.E.5(d) or Section 77 of the
Massachusetts Business Corporation Law.

         6. EXCHANGE OR REDEMPTION OF GSP STOCK. Shares of GSP Stock are subject
to exchange or redemption upon the terms and conditions set forth below:

                  (a) OPTIONAL EXCHANGE OF GSP STOCK.

                           (1) The Board of Directors may at any time, including
without limitation in the event of the reallocation, in one transaction or a
series of related transactions, by the Corporation and/or its subsidiaries of
all or substantially all of the properties and assets allocated to Genzyme
Surgical Products Division to any other Division of Genzyme, declare that each
of the outstanding shares of GSP Stock shall be exchanged, on an Exchange Date,
as determined by the Board of Directors, for (a) a number of fully paid and
nonassessable shares of GGD Stock (calculated to the nearest five decimal
places) equal to (1) 130% of the Fair Market Value of one share of the GSP Stock
(the "GSP Optional Exchange Amount") as of the date of the first public
announcement by the Corporation (the "GSP Optional Exchange Announcement Date")
of such exchange divided by (2) the Fair Market Value of one share of GGD Stock
as of such GSP Optional Exchange Announcement Date or (b) cash equal to the GSP
Optional Exchange Amount, or (c) any combination of GGD Stock and cash equal to
the GSP Optional Exchange Amount as determined by the Board of Directors.

                           (2) If the Corporation receives an opinion of
Qualified Tax Counsel that a Tax Event has occurred by reason of any Tax Law
Change, then the Board of Directors may at any time declare that each of the
outstanding shares of GSP Stock shall be exchanged, on an Exchange Date, as
determined by the Board of Directors, for a number of fully paid and
nonassessable shares of GGD Stock (calculated to the nearest five decimal
places) equal to (1) the Fair Market Value of one share of the GSP Stock as of
the date of the first public announcement by the Corporation of such exchange
divided by (2) the Fair Market Value of one share of GGD Stock as of such date.

                           (3) At any time at which all of the assets and
liabilities attributed to Genzyme Surgical Products Division (and no other
assets or liabilities of the Corporation or any subsidiary thereof) are held
directly or indirectly by one or more wholly-owned subsidiaries of the
Corporation (each, a "GSP Subsidiary"), the Board of Directors may, provided
that there are funds of the Corporation legally available therefor, exchange on
an Exchange Date, as determined by the Board of Directors, all of the
outstanding shares of GSP Stock for that number of the shares of common stock of
each GSP Subsidiary equal to the number of such GSP Subsidiary shares
outstanding immediately prior to such exchange multiplied by the GSP Allocation
Ratio, such shares of common stock of each GSP Subsidiary to be delivered to the


                                       19
<PAGE>

holders of shares of GSP Stock on the Exchange Date either directly or
indirectly through the delivery of shares of another GSP Subsidiary that owns
directly or indirectly all such shares, and to be divided among the holders of
GSP Stock on a pro rata basis in accordance with the number of shares of GSP
Stock held by each such holder, each of which shares of common stock of such GSP
Subsidiary shall be, upon such delivery, fully paid and nonassessable; PROVIDED,
HOWEVER, that upon any such exchange, any existing GSP Designated Shares shall
be cancelled in exchange for the allocation to Genzyme General of the direct or
indirect interest of the Corporation in any remaining outstanding shares of each
such GSP Subsidiary that are not transferred to the holders of GSP Stock in such
exchange.

         (b) MANDATORY EXCHANGE OR REDEMPTION OF OR PAYMENT OF DIVIDEND ON GSP
STOCK.

                  (1) GSP MANDATORY PAYMENT. In the event of the Disposition, in
one transaction or a series of related transactions, by the Corporation and/or
its subsidiaries of all or substantially all of the properties and assets
allocated to Genzyme Surgical Products Division to any person, entity or group
(other than a Disposition of a type set forth in subsection (2) of this
subsection (b)), on or prior to the 60th Business Day, or such earlier date
required under this Section IV.E.6, following the date of the GSP Mandatory
Payment Announcement (as defined in Section IV.E.6(d)(2)), the Corporation shall
select one of the following alternatives, as determined by the Board of
Directors in its discretion:

                           (A) provided that there are funds of the Corporation
legally available therefor, pay to the holders of the shares of GSP Stock a
dividend on a pro rata basis in accordance with the number of shares of GSP
Stock held by each such holder in cash, securities (other than shares of a
series of Common Stock) and/or other property having a Fair Market Value as of
the date of the Disposition in the aggregate equal to the Fair Market Value as
of the date of the Disposition of the GSP Net Proceeds of such Disposition; or

                           (B) provided that there are funds of the Corporation
legally available therefor,

                                    (i) if such Disposition involves all (not
merely substantially all) of the properties and assets attributed to Genzyme
Surgical Products Division, redeem or exchange as of a Redemption Date
determined by the Board of Directors, all outstanding shares of GSP Stock in
exchange for, on a pro rata basis, cash securities (other than shares of a
series of Common Stock) and/or other property having a Fair Market Value as of
the date of the Disposition in the aggregate equal to the Fair Market Value as
of the date of the Disposition of the GSP Net Proceeds of such Disposition; or

                                    (ii) if such Disposition involves
substantially all (but not all) of the properties and assets attributed to
Genzyme Surgical Products Division, redeem or exchange as of a Redemption Date
as determined by the Board of Directors such number of whole shares of GSP Stock
(which may be all, but not more than all, of such shares outstanding) as have in
the aggregate an average Closing Price during the period of ten (10) consecutive
Business Days beginning on the first Business Day immediately following the date
of the Estimated GSP Net Proceeds Announcement (as defined in Section
IV.E.6(d)(2)) closest to the


                                       20
<PAGE>

Fair Market Value as of the date of the Disposition of the GSP Net Proceeds of
such Disposition in consideration for, on a pro rata basis, cash, securities
(other than shares of a series of Common Stock) and/or other property having a
Fair Market Value as of the date of the Disposition in the aggregate equal to
such Fair Market Value of the GSP Net Proceeds; or

                           (C) declare that each outstanding share of GSP Stock
shall be exchanged as of an Exchange Date as determined by the Board of
Directors into a number of fully paid and nonassessable shares of GGD Stock
equal to 110% of the ratio (calculated to the nearest five decimal places) of
the average Closing Price of one share of GSP Stock over the period of ten (10)
consecutive Business Days beginning on the first Business Day immediately
following the date of the Estimated GSP Net Proceeds Announcement (as defined in
Section IV.E.6(d)(2)) to the average Closing Price of one share of GGD Stock
over the same ten Business Day period.

Any redemption or exchange of or dividend payment on GSP Stock made pursuant to
this Section IV.E.6(b)(1) or Section IV.E.6(c)(3) is hereinafter referred to as
a "GSP Mandatory Payment." Notwithstanding the foregoing provisions of this
Section IV.E.6(b), the Corporation shall redeem GSP Stock as provided by Section
IV.E.(6)(b)(1) only if the amount to be paid pursuant to such redemption is less
than or equal to the Available GSP Dividend Amount as of the Redemption Date.

                  (2) EXCEPTIONS TO MANDATORY PAYMENT. Notwithstanding the
foregoing Section IV.E.6(b)(1) or Section IV.E.6(c)(3), a GSP Mandatory Payment
shall not be required by the occurrence of a Disposition:

                           (A) by the Corporation of all or substantially all of
the Corporation's properties and assets in one transaction or a series of
related transactions, including such Disposition in connection with the
dissolution, liquidation or winding up of the Corporation and the distribution
of assets to stockholders as referred to in Section IV.E.4;

                           (B) of the properties and assets attributed to
Genzyme Surgical Products Division as contemplated by Section IV.E.6(a)(3) or
otherwise to all holders of GSP Stock divided among such holders on a pro rata
basis in accordance with the number of shares GSP Stock outstanding;

                           (C) to any person or entity controlled (as determined
by the Board of Directors) by the Corporation;

                           (D) in connection with a Related Business Transaction
in respect of Genzyme Surgical Products Division; or

                           (E) that is conditioned upon the affirmative vote of
the holders of GSP Stock, voting as a separate class.

         (c) TERMINATION OF CASH EXCHANGE RIGHT. If the Corporation receives an
opinion of Qualified Tax Counsel that, by reason of any Tax Law Change, the
right or obligation of the Corporation to exchange GSP Stock for cash,
securities or other property pursuant to Section IV.E.6(a)(1) or (3) or
IV.E.6(b) (each, a "GSP Cash Exchange Right") would cause a Tax Event


                                       21
<PAGE>

if not terminated, then the Board of Directors may at any time, by a vote of a
majority of the directors then in office, elect to terminate any or all such GSP
Cash Exchange Rights, with the result that the Corporation shall thereafter
have, depending on which GSP Cash Exchange Right(s) is (are) so terminated:

                  (1) under Section IV.E.6(a)(1) only the right to cause the
exchange of GSP Stock for GGD Stock and not for cash, securities or other
property other than capital stock of the Corporation,

                  (2) no right to effect an exchange under Section IV.E.6(a)(3),
and/or

                  (3) no right or obligation to effect a GSP Mandatory Payment
under Section IV.E.6(b), provided that if the Board shall no longer have the
right or obligation to effect a GSP Mandatory Payment under Section IV.E.6(b),
then if a GSP Mandatory Payment thereunder shall otherwise be or have been
required, the Corporation instead shall have the obligation to effect on or
prior to the first Business Day after the 90th day following the consummation of
such Disposition, a GSP Mandatory Payment pursuant to which it shall exchange
each outstanding share of GSP Stock for a number of fully paid and nonassessable
shares of GGD Stock (calculated to the nearest five decimal places) equal to (i)
the Fair Market Value of one share of the GSP Stock as of the date of the first
public announcement of such Disposition by the Corporation by press release
divided by (ii) the Fair Market Value of one share of GGD Stock as of such date.

         Notwithstanding the foregoing, the Board of Directors may not terminate
any GSP Cash Exchange Right during the period commencing on the date of a
Disposition requiring a GSP Mandatory Payment until the date upon which the
related Mandatory Payment is effected by the Corporation.

                  (1) If the Corporation determines to exchange shares of GSP

                  (3) in the event that at the time of any Disposition there are
outstanding any Convertible Securities convertible into or exercisable for
shares of GSP Stock that would give the holders rights to receive any dividend
related to the Disposition upon exercise, conversion or otherwise, or would
adjust as a result of such dividend to give the holder equivalent economic
rights, then the shares of GSP Stock underlying such Convertible Securities will
be taken into account for purposes of computing the GSP Allocation Ratio and
determining the terms of any dividend payment on such shares;

                  (4) in the event that as a result of or in connection with a

         (h) "Genzyme Surgical Products Division" shall mean, at any time, the
Corporation's interest in (i) surgical device, closure, instrument, biomaterial
and biotherapeutic businesses, products, or development or research programs

F.       GENZYME TISSUE REPAIR DIVISION COMMON STOCK

         1. AUTHORIZED AMOUNTS AND DESIGNATIONS. Forty million (40,000,000)
shares of Common Stock are designated as a series of Common Stock with the
following designation: Genzyme Tissue Repair Division Common Stock (the "GTR
Stock"). To the extent legally permitted, such number of shares may be increased
or decreased by vote of the Board of Directors, provided that no decrease shall
reduce the number of shares of GTR Stock to a number less than the number of
shares of such series then outstanding plus the number of shares of such series
reserved for issuance upon the exercise of outstanding options, rights or
warrants or upon the conversion of any outstanding securities issued by the
Corporation convertible into such series of Common Stock. A description of the
GTR Stock and a statement of its preferences, voting powers, qualifications and
special or relative rights or privileges is as follows:

         2. DIVIDENDS AND DISTRIBUTIONS. Subject to the express terms of any
outstanding series of Preferred Stock, dividends may be declared and paid upon
the GTR Stock, in such amounts and at such times as the Board of Directors may
determine, only out of the lesser of (a) funds of the Corporation legally
available therefor and (b) the Available GTR Dividend Amount.


                                       27
<PAGE>

         3. VOTING RIGHTS. The holders of GTR Stock, voting together with the
holders of shares of all other series of Common Stock as a single class of
stock, shall have the exclusive right to vote for the election of directors and
on all other matters requiring action by the stockholders or submitted to the
stockholders for action, except as may be determined by the Board of Directors
in establishing any series of Common or Preferred Stock or as may otherwise be
required by law. Each share of GTR Stock shall entitle the holder thereof to .06
vote through December 31, 2000. On January 1, 2001 and on each January 1 every
two years thereafter, the number of votes to which the holder of each share of
GTR Stock shall be entitled shall be adjusted and fixed for two-year periods to
equal the quotient (expressed as a decimal and rounded to the nearest two
decimal places) obtained by dividing (i) the Fair Market Value of one share of
GTR Stock by (ii) Fair Market Value of one share of GGD Stock as of such date.
If no shares of GGD Stock are outstanding on such date, then all other series of
voting Common Stock outstanding on such date shall have a number of votes such
that each share of the series of outstanding Common Stock that has the highest
Fair Market Value per share on such date (the "Base Series") shall have one vote
and each share of each other series of outstanding Common Stock shall have the
number of votes determined according to the immediately preceding sentence,
treating, for such purpose, the Base Series as the GGD Stock in such sentence.
If shares of GTR Stock are entitled to vote separately as a class, each share of
GTR Stock shall have one vote.

         4. LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any voluntary or
involuntary liquidation, dissolution or winding up of the Corporation, the
rights of the holders of GTR Stock shall be as follows:

                  (a) After the Corporation has satisfied or made provision for
its debts and obligations and for the payment to the holders of shares of any
class or series of capital stock having preferential rights to receive
distributions of the net assets of the Corporation (including any accumulated
and unpaid dividends), the holders of GTR Stock shall be entitled to receive the
net assets of the Corporation remaining for distribution, on a per share basis
in proportion to the respective liquidation units per share of all series of
Common Stock. Each share of GTR Stock shall, subject to Section G.4. below, have
58 liquidation units.

                  (b) For the purposes of Section IV.D.3(a)., any merger or
business combination involving the Corporation or any sale of all or
substantially all of the assets of the Corporation shall not be treated as a
liquidation.

         5. SPECIAL VOTING RIGHTS. The Corporation shall not, without approval
by the holders of the GTR Stock at a meeting at which a quorum is present and
the votes cast in favor of the proposal exceed those cast against:

                  (a) allow any proceeds from the Disposition of the properties
or assets allocated to Genzyme Tissue Repair Division to be used in the business
of any other Division without fair compensation being allocated to Genzyme
Tissue Repair Division as determined by the Board of Directors;

                  (b) allow any properties or assets allocated to Genzyme Tissue
Repair Division to be used in the business of any other Division or for the
declaration or payment of any dividend or


                                       28
<PAGE>

distribution on any series of Common Stock other than the GTR Stock without fair
compensation being allocated to Genzyme Tissue Repair Division as determined by
the Board of Directors;

                  (c) issue, sell or otherwise distribute shares of GTR Stock
without allocating the proceeds or other benefits of such issuance, sale or
distribution to Genzyme Tissue Repair Division; provided, however, that the
Corporation may without such approval issue GTR Designated Shares;

                  (d) change the rights or preferences of the GTR Stock so as to
affect the GTR Stock adversely; or

                  (e) effect any merger or business combination involving the
Corporation as a result of which (i) the holders of all series of Common Stock
of the Corporation shall no longer own, directly or indirectly, at least fifty
percent (50%) of the voting power of the surviving corporation and (ii) the
holders of all series of Common Stock of the Corporation do not receive the same
form of consideration, distributed among such holders in proportion to the
Market Capitalization of each series of Common Stock as of the date of the first
public announcement of such merger or business combination.

         Notwithstanding the foregoing, if the Corporation receives an opinion
of Qualified Tax Counsel that, by reason of any Tax Law Change, the special
voting rights of the GTR Stock set forth in this subsection 5 would cause a Tax
Event absent the termination of such rights, then the Corporation may, by vote
of a majority of the stock outstanding and entitled to vote thereon, voting
together as a single class, authorize an amendment to these Articles of
Organization to effect the termination of such rights in order to avoid the
occurrence of such Tax Event. Any such amendment shall not be deemed to change
the rights or preferences of the GTR Stock so as to affect the GSP Stock
adversely as contemplated by either Section IV.F.5(d) or Section 77 of the
Massachusetts Business Corporation Law.

         6. EXCHANGE OR REDEMPTION OF GTR STOCK. Shares of GTR Stock are subject
to exchange or redemption upon the terms and conditions set forth below:

                  (a) OPTIONAL EXCHANGE OF GTR STOCK.

                           (1) The Board of Directors may at any time, including
without limitation in the event of the reallocation, in one transaction or a
series of related transactions, by the Corporation and/or its subsidiaries of
all or substantially all of the properties and assets allocated to Genzyme
Tissue Repair Division to any other Division of Genzyme, declare that each of
the outstanding shares of GTR Stock shall be exchanged, on an Exchange Date, as
determined by the Board of Directors, for (a) a number of fully paid and
nonassessable shares of GGD Stock (calculated to the nearest five decimal
places) equal to (1) 130% of the Fair Market Value of one share of the GTR Stock
(the "GTR Optional Exchange Amount") as of the date of the first public
announcement by the Corporation (the "GTR Optional Exchange Announcement Date")
of such exchange divided by (2) the Fair Market Value of one share of GGD Stock
as of such GTR Optional Exchange Announcement Date or (b) cash equal to the GTR
Optional Exchange Amount, or (c) any combination of GGD Stock and cash equal to
the GTR Optional Exchange Amount as determined by the Board of Directors.


                                       29
<PAGE>

                           (2) If the Corporation receives an opinion of
Qualified Tax Counsel that a Tax Event has occurred by reason of any Tax Law
Change, then the Board of Directors may at any time declare that each of the
outstanding shares of GTR Stock shall be exchanged, on an Exchange Date, as
determined by the Board of Directors, for a number of fully paid and
nonassessable shares of GGD Stock (calculated to the nearest five decimal
places) equal to (1) the Fair Market Value of one share of the GTR Stock as of
the date of the first public announcement by the Corporation of such exchange
divided by (2) the Fair Market Value of one share of GGD Stock as of such date.

                           (3) At any time at which all of the assets and
liabilities attributed to Genzyme Tissue Repair Division (and no other assets or
liabilities of the Corporation or any subsidiary thereof) are held directly or
indirectly by one or more wholly-owned subsidiaries of the Corporation (each, a
"GTR Subsidiary"), the Board of Directors may, provided that there are funds of
the Corporation legally available therefor, exchange on an Exchange Date, as
determined by the Board of Directors, all of the outstanding shares of GTR Stock
for that number of the shares of common stock of each GTR Subsidiary equal to
the number of such GTR Subsidiary shares outstanding immediately prior to such
exchange multiplied by the GTR Allocation Ratio, such shares of common stock of
each GTR Subsidiary to be delivered to the holders of shares of GTR Stock on the
Exchange Date either directly or indirectly through the delivery of shares of
another GTR Subsidiary that owns directly or indirectly all such shares, and to
be divided among the holders of GTR Stock on a pro rata basis in accordance with
the number of shares of GTR Stock held by each such holder, each of which shares
of common stock of such GTR Subsidiary shall be, upon such delivery, fully paid
and nonassessable; PROVIDED, HOWEVER, that upon any such exchange, any existing
GTR Designated Shares shall be cancelled in exchange for the allocation to
Genzyme General of the direct or indirect interest of the Corporation in any
remaining outstanding shares of each such GTR Subsidiary that are not
transferred to the holders of GTR Stock in such exchange.

                  (b) MANDATORY EXCHANGE OR REDEMPTION OF OR PAYMENT OF DIVIDEND
ON GTR STOCK.

                           (1) GTR MANDATORY PAYMENT. In the event of the
Disposition, in one transaction or a series of related transactions, by the
Corporation and/or its subsidiaries of all or substantially all of the
properties and assets allocated to Genzyme Tissue Repair Division to any person,
entity or group (other than a Disposition of a type set forth in subsection (2)
of this subsection (b)), on or prior to the 60th Business Day, or such earlier
date required under this Section IV.F.6, following the date of the GTR Mandatory
Payment Announcement (as defined in Section IV.F.6(d)(2)), the Corporation shall
select one of the following alternatives, as determined by the Board of
Directors in its discretion:

                                    (A) provided that there are funds of the
Corporation legally available therefor, pay to the holders of the shares of GTR
Stock a dividend on a pro rata basis in accordance with the number of shares of
GTR Stock held by each such holder in cash, in securities (other than shares of
a series of Common Stock) and/or other property having a Fair Market Value as of
the date of the Disposition in the aggregate equal to the Fair Market Value as
of the date of the Disposition of the GTR Net Proceeds of such Disposition; or


                                       30
<PAGE>

                                    (B) provided that there are funds of the
Corporation legally available therefor,

                                             (i) if such Disposition involves
all (not merely substantially all) of the properties and assets attributed to
Genzyme Tissue Repair Division, redeem or exchange as of a Redemption Date
determined by the Board of Directors, all outstanding shares of GTR Stock in
exchange for, on a pro rata basis, cash, securities (other than shares of a
series of Common Stock) and/or other property having a Fair Market Value as of
the date of the Disposition in the aggregate equal to the Fair Market Value as
of the date of the Disposition of the GTR Net Proceeds of such Disposition; or

                                             (ii) if such Disposition involves
substantially all (but not all) of the properties and assets attributed to
Genzyme Tissue Repair Division, redeem or exchange as of a Redemption Date as
determined by the Board of Directors such number of whole shares of GTR Stock
(which may be all, but not more than all, of such shares outstanding) as have in
the aggregate an average Closing Price during the period of ten (10) consecutive
Business Days beginning on the first Business Day immediately following the date
of the Estimated GTR Net Proceeds Announcement (as defined in Section
IV.F.6(d)(2)) closest to the Fair Market Value as of the date of the Disposition
of the GTR Net Proceeds of such Disposition in consideration for, on a pro rata
basis, cash, securities (other than shares of a series of Common Stock), or
other property having a Fair Market Value as of the date of the Disposition in
the aggregate equal to such Fair Market Value of the GTR Net Proceeds; or

                                    (C) declare that each outstanding share of
GTR Stock shall be exchanged as of an Exchange Date as determined by the Board
of Directors into a number of fully paid and nonassessable shares of GGD Stock
equal to 110% of the ratio (calculated to the nearest five decimal places) of
the average Closing Price of one share of GTR Stock over the period of ten (10)
consecutive Business Days beginning on the first Business Day immediately
following the date of the Estimated GTR Net Proceeds Announcement (as defined in
Section IV.F.6(d)(2)) to the average Closing Price of one share of GGD Stock
over the same ten Business Day period.

Any redemption or exchange of or dividend payment on GTR Stock made pursuant to
this Section IV.F.6(b)(1) or Section IV.F.6(c)(3) is hereinafter referred to as
a "GTR Mandatory Payment." Notwithstanding the foregoing provisions of this
Section IV.F.6(b), the Corporation shall redeem GTR Stock as provided by Section
IV.F6(b)(1)(b) only if the amount to be paid pursuant to such redemption is less
than or equal to the Available GTR Dividend Amount as of the Redemption Date.

                           (2) EXCEPTIONS TO MANDATORY PAYMENT. Notwithstanding
the foregoing Section IV.F.6(b)(1) or Section IV.F.6(c)(3), a GTR Mandatory
Payment shall not be required by the occurrence of a Disposition:

                           (A) by the Corporation of all or substantially all of
the Corporation's properties and assets in one transaction or a series of
related transactions, including such Disposition in connection with the
dissolution, liquidation or winding up of the Corporation and the distribution
of assets to stockholders as referred to in Section IV.F.4;


                                       31
<PAGE>

                           (B) of the properties and assets attributed to
Genzyme Tissue Repair Division as contemplated by Section IV.F.6(a)(3) or
otherwise to all holders of GTR Stock divided among such holders on a pro rata
basis in accordance with the number of shares GTR Stock outstanding;

                           (C) to any person or entity controlled (as determined
by the Board of Directors) by the Corporation;

                           (D) in connection with a Related Business Transaction
in respect of Genzyme Tissue Repair Division; or

                           (E) that is conditioned upon the affirmative vote of
the holders of GTR Stock, voting as a separate class.

         (c) TERMINATION OF CASH EXCHANGE RIGHT. If the Corporation receives an
opinion of Qualified Tax Counsel that, by reason of any Tax Law Change, the
right or obligation of the Corporation to exchange GTR Stock for cash,
securities or other property pursuant to Section IV.F.6(a)(1) or (3) or
IV.E.6(b) (each, a "GTR Cash Exchange Right") would cause a Tax Event if not
terminated, then the Board of Directors may at any time, by a vote of a majority
of the directors then in office, elect to terminate any or all such GTR Cash
Exchange Rights, with the result that the Corporation shall thereafter have,
depending on which GTR Cash Exchange Right(s) is (are) so terminated:

                  (1) under Section IV.F.6(a)(1) only the right to cause the
exchange of GTR Stock for GGD Stock and not for cash, securities or other
property other than capital stock of the Corporation,

                  (2) no right to effect an exchange under Section IV.F.6(a)(3),
and/or

                  (3) no right or obligation to effect a GTR Mandatory Payment
under Section IV.F.6(b), provided that if the Board shall no longer have the
right or obligation to effect a GTR Mandatory Payment under Section IV.F.6(b),
then if a GTR Mandatory Payment thereunder shall otherwise be or have been
required, the Corporation instead shall have the obligation to effect on or
prior to the first Business Day after the 90th day following the consummation of
such Disposition, a GTR Mandatory Payment pursuant to which it shall exchange
each outstanding share of GTR Stock for a number of fully paid and nonassessable
shares of GGD Stock (calculated to the nearest five decimal places) equal to (i)
the Fair Market Value of one share of the GTR Stock as of the date of the first
public announcement of such Disposition by the Corporation by press release
divided by (ii) the Fair Market Value of one share of GGD Stock as of such date.

         Notwithstanding the foregoing, the Board of Directors may not terminate
any GTR Cash Exchange Right during the period commencing on the date of a
Disposition requiring a GTR Mandatory Payment until the date upon which the
related Mandatory Payment is effected by the Corporation.

                  (3) in the event that at the time of any Disposition there are
outstanding any Convertible Securities convertible into or exercisable for
shares of GTR Stock that would give the holders rights to receive any dividend
related to the Disposition upon exercise, conversion or otherwise, or would
adjust as a result of such dividend to give the holder equivalent economic
rights, then the shares of GTR Stock underlying such Convertible Securities


                                       34
<PAGE>

will be taken into account for purposes of computing the GTR Allocation Ratio

provided that such excess shall be reduced by any amount necessary to enable

determined in accordance with generally accepted accounting principles, with all

G.       GENERAL PROVISIONS REGARDING THE COMMON STOCK

         1. GENERAL EXCHANGE AND REDEMPTION PROVISIONS. In the event of any
exchange or mandatory redemption or dividend pursuant to the provisions of these
Articles of Organization, the following provisions shall apply:

                  (a) Any notice delivered hereunder shall be sent by the
Corporation to each record holder of shares of the Common Stock to be exchanged
or redeemed or upon which will be made a dividend payment (the "Exchange Stock")
and to the holders of Convertible Securities that are convertible into or
exchangeable or exercisable for shares of such Exchange Stock (unless alternate
provision for such notice is made pursuant to the terms of such Convertible
Securities). Unless otherwise required by any other provision of these Articles
of Organization, such notice shall be sent not less nor more than 60 days prior
to the Exchange Date.

                  (b) With respect to an exchange or redemption, such notice
shall state, to the extent and in the manner applicable, (1) the number of
shares of Exchange Stock outstanding on the record date for such exchange or
redemption and the number of such shares to be redeemed or exchanged, (2) the
aggregate amount and form of consideration, including shares of Common Stock,
other securities, cash or other property, that will be paid on the Exchange Date
or Redemption Date upon the exchange or redemption of the shares of Exchange
Stock, (3) the amount and form of such consideration to be received by such
holder with respect to each share of the Exchange Stock held by such holder,
including details as to the calculation thereof, (4) the Exchange Date or
Redemption Date, (5) the place or places where certificates for shares of
Exchange Stock, properly endorsed or assigned for transfer are to be surrendered
for delivery of such consideration (unless the Corporation shall waive such
requirement), (6), if applicable, a statement to the effect that, subject to
Section IV.G.1(e) dividends on shares of Exchange Stock shall cease to be paid
as of such Exchange Date or Redemption Date, (7) the number of shares of
Exchange Stock into or for which outstanding Convertible Securities are
convertible, exchangeable or exercisable as of the record date for such exchange
or redemption and the conversion, exchange or exercise price thereof and (8) in
the case of notice to holders of Convertible Securities, a statement to the
effect that a holder of Convertible Securities shall be entitled to receive its
pro rata portion of the consideration, as applicable, upon redemption or
exchange only if such holder properly converts, exchanges or exercises such
Convertible Securities (unless the terms of a Convertible Security provide
otherwise) on or prior to the Exchange Date or Redemption Date and a statement
as to what, if anything, such holder will be entitled to receive pursuant to the
terms of such Convertible Securities if such holder thereafter converts,
exchanges or exercises such Convertible Securities.


                                       38
<PAGE>

                  (c) Any notice delivered under this Section IV.G.1 shall be
sent by first-class mail, postage prepaid at such holder's address as the same
appears on the stock transfer books of the Corporation. Neither the failure to
mail such notice to any particular holder of shares of Exchange Stock nor any
defect therein shall affect the sufficiency thereof with respect to any other
holder of shares of Exchange Stock or the validity of any such exchange,
redemption or dividend payment.

                  (d) The Corporation shall not be required to issue or deliver
fractional shares of any series of Common Stock, capital stock, securities or
other property to any holder of shares of Exchange Stock upon any such exchange,
redemption or dividend payment. If more than one share of Exchange Stock shall
be held by the same holder of record, the Corporation shall aggregate the number
of shares of any security that shall be issuable or any other property that
shall be distributable to such holder upon any such exchange, redemption or
dividend payment. If fractional shares of any security would be required to be
issued or distributed to the holder of Exchange Stock, the Corporation shall, if
such fractional shares are not issued or distributed to such holder, either
arrange for the disposition of such fraction by or on behalf of such holder or
pay the Fair Market Value (without interest) of such fractional shares.

                  (e) No adjustments in respect of dividends shall be made upon
the exchange or redemption of any shares of Exchange Stock; provided, however,
that if the Exchange Date shall be subsequent to the record date for determining
holders of Exchange Stock entitled to the payment of a dividend or other
distribution thereon or with respect thereto, the holders of shares of Exchange
Stock at the close of business on such record date shall be entitled to receive
the dividend or other distribution payable on or with respect to such shares on
the date set for payment of such dividend or other distribution, notwithstanding
the exchange or redemption of such shares.

                  (f) With respect to an exchange or redemption, before any
holder of shares of Exchange Stock shall be entitled to receive the
consideration to be received by such holder with respect to the exchange or
redemption of such shares of Exchange Stock, such holder shall surrender at such
place as the Corporation shall specify certificates for such shares of Exchange
Stock, properly endorsed or assigned for transfer (unless the Corporation shall
waive such requirement). The Corporation will as soon as practicable after such
surrender of certificates representing such shares of Exchange Stock deliver to
the person for whose account such shares of Exchange Stock were so surrendered,
or to the nominee or nominees of such person, the consideration to which such
person shall be entitled as aforesaid, together with any fractional share
payment contemplated by Section IV.G.1(d).

                  (g) With respect to an exchange or redemption, from and after
the Exchange Date, all rights of a holder of shares of Exchange Stock shall
cease except for the right, upon surrender of the certificates representing such
shares of Exchange Stock, to receive the consideration for which such shares
were exchanged are redeemed, together with any fractional share payment
contemplated by Section IV.G.1(d), and rights to dividends as provided in
Section IV.G.1(e). No holder of a certificate that immediately prior to the
Exchange Date represented shares of Exchange Stock shall be entitled to receive
any dividend or interest payment or other distribution with respect to the
shares of any security or instrument for which the Exchange Stock was exchanged
or redeemed until surrender of such holder's certificate for a certificate or
certificates


                                       39
<PAGE>

or instrument or instruments representing such security (unless the
Corporation shall waive such requirement). Subject to applicable escheat and
similar laws, upon such surrender, there shall be paid to the holder the amount
of any dividend or interest payments or other distributions (without interest)
which theretofore became payable with respect to a record date after the
Exchange Date, but that were not paid by reason of the foregoing, with respect
to the number of shares of the kind of securities represented by the certificate
or certificates issued upon such surrender. From and after the Exchange Date,
the Corporation shall, however, be entitled to treat the certificates for
Exchange Stock that have not yet been surrendered for exchange or redemption as
evidencing the ownership of the number of shares of the kind of securities for
which the shares of Exchange Stock represented by such certificates shall have
been exchanged or redeemed, notwithstanding the failure to surrender such
certificates.

                  (h) The Corporation will pay any and all documentary, stamp or
similar issue or transfer taxes that may be payable in respect of the issue or
delivery of any securities in exchange for or upon redemption of or dividend
payment on shares of Exchange Stock pursuant hereto. The Corporation shall not,
however, be required to pay any tax that may be payable in respect of any
transfer involved in the issue and delivery of any such securities issued in
exchange or upon redemption or as a dividend in a name other than that in which
the shares of Exchange Stock so exchanged or redeemed or paid as a dividend upon
were registered and no such issue or delivery shall be made unless and until the
person requesting such issue has paid to the Corporation the amount of any such
tax, or has established to the satisfaction of the Corporation that such tax has
been paid or that no such tax is due.

                  (i) After the Exchange Date, any share of Exchange Stock
issued upon conversion or exercise of any Convertible Security shall,
immediately upon issuance pursuant to such conversion or exercise and without
any notice or any other action on the part of the Corporation or its Board of
Directors or the holder of such share of Exchange Stock, be exchanged for the
amount of cash, securities and/or other property thereof (together with any
payments in lieu of fractional shares or dividends, if any) that a holder of
such Convertible Security would have been entitled to receive pursuant to the
terms of such Convertible Security had such terms provided that the conversion
privilege in effect immediately prior to any exchange by the Corporation of any
shares of Exchange Stock would be adjusted so that the holder of any such
Convertible Security thereafter surrendered for conversion would be entitled to
receive the amount of cash, securities and/or other property he or she would
have owned immediately following such action had such Convertible Security been
converted immediately prior to such exchange. The foregoing provisions shall not
apply to the extent that equivalent adjustments are otherwise made pursuant to
the provisions of such Convertible Security.

         2. VOTING OF CONTROLLED SHARES. Shares of any series of Common Stock
held by a corporation or other entity controlled by the Corporation (other than
an employee benefit plan) shall be voted on any proposal requiring a vote of the
holders of such series in the same proportion as votes are cast for or against
such proposal by all other holders of such series.

         3. DISCRIMINATION BETWEEN CLASSES OF COMMON STOCK. Subject to the
provisions of each series of Common Stock regarding the payment of dividends on
such series of Common Stock, the Board of Directors may, in its sole discretion,
declare and pay dividends exclusively on any series of Common Stock, or all
series, in equal or unequal amounts, notwithstanding the


                                       40
<PAGE>

amounts available for the payment of dividends on any series, the respective
voting and liquidation rights of each series, the amounts of prior dividends
declared on each series or any other factor.

         4. ADJUSTMENTS RELATIVE TO VOTING RIGHTS AND LIQUIDATION. If at any
time the Corporation shall in any manner subdivide (by stock split,
reclassification or otherwise) or combine (by reverse stock split,
reclassification or otherwise) the outstanding shares of any series of Common
Stock, or pay a dividend or make a distribution in shares of any series of
Common Stock to holders of such series, the per share voting rights and the
liquidation units of each series of Common Stock other than the GGD Stock shall
be appropriately adjusted so as to avoid dilution in the aggregate voting and
liquidation rights of any series. The issuance by the Corporation of shares of
any series of Common Stock (whether by a dividend or otherwise) to the holders
of any other series of Common Stock shall not require adjustment pursuant to
this paragraph.

         5. RANK. All series of Common Stock shall rank junior with respect to
the payment of dividends and the distribution of assets to all series of the
Corporation's Preferred Stock that specifically provide that they shall rank
prior to the Common Stock. Nothing herein shall preclude the Board from creating
any series of Preferred Stock ranking on a parity with or prior to the Common
Stock as to the payment of dividends or the distribution of assets.

         6. FRACTIONAL SHARES. Any series of Common Stock may be issued in
fractions of a share which shall entitle the holder, in proportion to such
holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of such series of Common Stock.

         7. DEFINITIONS. As used in these Articles of Organization, the
following terms shall have the following meanings (with terms defined in the
singular having comparable meaning when used in the plural and vice versa),

regular way on the principal national securities exchange on which such shares
are listed or admitted to trading (which shall be the national securities
exchange on which the greatest number of shares of such series of stock has been
traded during such consecutive trading days), or, if there is no such sale on
any such day, the mean of the bid and asked prices on such day, or (y) if such
shares are not listed or admitted to trading on any such exchange, the closing
price, if reported, or, if the closing price is not reported, the mean of the

                           (2) in the case of securities other than securities

H.       DESCRIPTION OF THE PREFERRED STOCK

         1. UNDESIGNATED 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.

         2. TERMS OF THE SERIES A, SERIES B, SERIES C AND SERIES D JUNIOR
PARTICIPATING PREFERRED STOCK.

                  (a) AUTHORIZED AMOUNTS AND DESIGNATIONS. Two million shares of
Preferred Stock of the Corporation are designated as Series A Junior
Participating Preferred Stock (the "Series A Preferred Stock"), 400,000 shares
of Preferred Stock are designated as Series B Junior Participating Preferred
Stock (the "Series B Preferred Stock"), 400,000 shares of Preferred Stock are
designated as Series C Junior Participating Preferred Stock (the "Series C
Preferred Stock,") and 600,000 shares of Preferred Stock are designated as
Series D Junior Preferred Stock (the "Series D Preferred Stock" and, together
with the Series A Preferred Stock, the Series B Preferred Stock, the Series C
Preferred Stock and any other series of Preferred Stock so designated by the
Corporation's Board of Directors, the "Junior Preferred Stock"). To the extent
legally permitted, such numbers of shares may be increased or decreased by vote
of the Board of Directors, provided that no decrease shall reduce the number of
shares of Junior Preferred Stock of any series to a number less than the number
of shares of such series then outstanding plus the number of shares of such
series reserved for issuance upon the exercise of outstanding options, rights or
warrants or upon the conversion of any outstanding securities issued by the

                  (b) SERIES A PREFERRED STOCK. A description of the Series A
Preferred Stock and a statement of its preferences, voting powers,
qualifications and special or relative rights or privileges is as follows:

                           (1) DIVIDENDS AND DISTRIBUTIONS.


                                       44
<PAGE>

                                    (A) Subject to the prior and superior rights
of the holders of any shares of any series of Preferred Stock ranking prior and
superior to the Series A Preferred Stock with respect to dividends, the holders
of shares of Series A Preferred Stock, in preference to the holders of all
shares of common stock of the Corporation (the "Common Shares"), and of any
other junior stock, shall be entitled to receive, when, as and if declared by
the Board of Directors out of funds legally available for the purpose, quarterly
dividends payable in cash on the first day of March, June, September and
December in each year (each such date being referred to herein as a "Quarterly
Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date
after the first issuance of a share or fraction of a share of Series A Preferred
Stock, in an amount per share (rounded to the nearest cent) equal to the greater
of (a) $1.00 or (b) subject to the provision for adjustment hereinafter set
forth, 100 times the aggregate per share amount of all cash dividends, and 100
times the aggregate per share amount (payable in kind) of all non-cash dividends
or other distributions, other than a dividend on shares of Genzyme General
Division Common Stock (the "GGD Stock") payable in shares of GGD Stock or a
subdivision of the outstanding shares of GGD Stock (by reclassification or
otherwise), declared on the GGD Stock since the immediately preceding Quarterly
Dividend Payment Date or, with respect to the first Quarterly Dividend Payment
Date, since the first issuance of any share or fraction of a share of Series A
Preferred Stock. In the event the Corporation shall at any time after June 12,
1997 declare or pay any dividend on shares of GGD Stock payable in shares of GGD
Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of GGD Stock (by reclassification or otherwise than by
payment of a dividend in shares of GGD Stock) into a greater or lesser number of
shares of GGD Stock, then in each such case the amount to which holders of
shares of Series A Preferred Stock were entitled immediately prior to such event
under clause (b) of the preceding sentence shall be adjusted by multiplying such
amount by a fraction, the numerator of which is the number of shares of GGD
Stock outstanding immediately after such event and the denominator of which is
the number of shares of GGD Stock that were outstanding immediately prior to
such event.

                                    (B) The Corporation shall declare a dividend
or distribution on the Series A Preferred Stock as provided in Section
IV.H.2(b)(1)(A) immediately after it declares a dividend or distribution on any
shares of GGD Stock (other than a dividend payable in shares of GGD Stock),
provided that, in the event no dividend or distribution shall have been declared
on the GGD Stock during the period between any Quarterly Dividend Payment Date
and the next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per
share on the Series A Preferred Stock shall nevertheless be payable on such
subsequent Quarterly Dividend Payment Date.

                                    (C) Dividends shall begin to accrue and be
cumulative on outstanding shares of Series A Preferred Stock from the Quarterly
Dividend Payment Date next preceding the date of issue of such shares, unless
the date of issue of such shares is prior to the record date for the first
Quarterly Dividend Payment Date, in which case dividends on such shares shall
begin to accrue from the date of issue of such shares, or unless the date of
issue is a Quarterly Dividend Payment Date or is a date after the record date
for the determination of holders of shares of Series A Preferred Stock entitled
to receive a quarterly dividend and before such Quarterly Dividend Payment Date,
in either of which events such dividends shall begin to accrue and be cumulative
from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall
not bear interest. Dividends paid on the shares of Series A Preferred Stock in
an


                                       45
<PAGE>

amount less than the total amount of such dividends at the time accrued and
payable on such shares shall be allocated pro rata on a share-by-share basis
among all such shares at the time outstanding. The Board of Directors may fix a
record date for the determination of holders of shares of Series A Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be not more than 60 days prior to the date
fixed for the payment thereof.

                  (2) VOTING RIGHTS. The holders of shares of Series A Preferred
Stock shall have the following voting rights:

                           (A) Subject to the provision for adjustment
hereinafter set forth, each share of Series A Preferred Stock shall entitle the
holder thereof to 100 votes on all matters submitted to a vote of the
stockholders of the Corporation. In the event the Corporation shall at any time
after June 12, 1997 declare or pay any dividend on any shares of GGD Stock
payable in shares of GGD Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of GGD Stock (by reclassification or
otherwise than by payment of a dividend in shares of GGD Stock) into a greater
or lesser number of shares of GGD Stock, then in each such case the number of
votes per share to which holders of shares of Series A Preferred Stock were
entitled immediately prior to such event shall be adjusted by multiplying such
number by a fraction, the numerator of which is the number of shares of GGD
Stock outstanding immediately after such event and the denominator of which is
the number of shares of GGD Stock that were outstanding immediately prior to
such event.

                           (B) Except as otherwise provided herein, in the
Articles of Organization, in any other vote of the Board of Directors of the
Corporation creating a series of Preferred Stock, or by law, the holders of
shares of Series A Preferred Stock and the holders of Common Shares and any
other capital stock of the Corporation having general voting rights shall vote
together as one series on all matters submitted to a vote of stockholders of the
Corporation.

                           (C) Except as set forth herein or as otherwise
provided by law, holders of Series A Preferred Stock shall have no voting
rights.

                  (3) LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any
liquidation, dissolution or winding up of the Corporation, no distribution shall
be made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock unless, prior thereto, the holders of shares of Series A
Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series A
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 100
times the aggregate amount to be distributed per share to holders of shares of
GGD Stock, or (2) to the holders of shares of stock ranking on a parity (either
as to dividends or upon liquidation, dissolution or winding up) with the Series
A Preferred Stock, except distributions made ratably on the Series A Preferred
Stock and all other such parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up. In the event the Corporation shall at any time after
June 12, 1997 declare or pay any dividend on shares of GGD Stock payable in
shares of GGD Stock, or effect a


                                       46
<PAGE>

subdivision or combination or consolidation of the outstanding shares of GGD
Stock (by reclassification or otherwise than by payment of a dividend in shares
of GGD Stock) into a greater or lesser number of shares of GGD Stock, then in
each such case the aggregate amount to which holders of shares of Series A
Preferred Stock were entitled immediately prior to such event under the proviso
in clause (1) of the preceding sentence shall be adjusted by multiplying such
amount by a fraction, the numerator of which is the number of shares of GGD
Stock outstanding immediately after such event and the denominator of which is
the number of shares of GGD Stock that were outstanding immediately prior to
such event.

                  (4) CONSOLIDATION, MERGER, ETC. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
Common Shares are exchanged for or changed into other stock or securities, cash
and/or any other property, then in any such case each share of Series A
Preferred Stock shall at the same time be similarly exchanged or changed into an
amount per share (subject to the provision for adjustment hereinafter set forth)
equal to 100 times the aggregate amount of stock, securities, cash and/or any
other property (payable in kind), as the case may be, into which or for which
each share of GGD Stock is changed or exchanged. In the event the Corporation
shall at any time after June 12, 1997 declare or pay any dividend on any shares
of GGD Stock payable in shares of GGD Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of GGD Stock (by
reclassification or otherwise than by payment of a dividend in shares of GGD
Stock) into a greater or lesser number of shares of GGD Stock, then in each such
case the amount set forth in the preceding sentence with respect to the exchange
or change of shares of Series A Preferred Stock shall be adjusted by multiplying
such amount by a fraction, the numerator of which is the number of shares of GGD
Stock outstanding immediately after such event and the denominator of which is
the number of shares of GGD Stock that were outstanding immediately prior to
such event.

         (c) SERIES B PREFERRED STOCK. A description of the Series B Preferred
Stock and a statement of its preferences, voting powers, qualifications and
special or relative rights or privileges is as follows:

                  (1) DIVIDENDS AND DISTRIBUTIONS.

                           (A) Subject to the prior and superior rights of the
holders of any shares of any series of Preferred Stock ranking prior and
superior to the Series B Preferred Stock with respect to dividends, the holders
of shares of Series B Preferred Stock, in preference to the holders of all
Common Shares, and of any other junior stock, shall be entitled to receive,
when, as and if declared by the Board of Directors out of funds legally
available for the purpose, quarterly dividends payable in cash on the first day
of March, June, September and December in each year (each such date being
referred to herein as a "Quarterly Dividend Payment Date"), commencing on the
first Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Series B Preferred Stock, in an amount per share (rounded
to the nearest cent) equal to the greater of (a) $1.00 or (b) subject to the
provision for adjustment hereinafter set forth, 100 times the aggregate per
share amount of all cash dividends, and 100 times the aggregate per share amount
(payable in kind) of all non-cash dividends or other distributions, other than a
dividend on shares of Genzyme Tissue Repair Division Common Stock (the "GTR
Stock") payable in shares of GTR Stock or a subdivision of the outstanding
shares of GTR Stock


                                       47
<PAGE>

(by reclassification or otherwise), declared on the GTR Stock since the
immediately preceding Quarterly Dividend Payment Date or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series B Preferred Stock. In the event the Corporation
shall at any time after June 12, 1997 declare or pay any dividend on any shares
of GTR Stock payable in shares of GTR Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of GTR Stock (by
reclassification or otherwise than by payment of a dividend in shares of GTR
Stock) into a greater or lesser number of shares of GTR Stock, then in each such
case the amount to which holders of shares of Series B Preferred Stock were
entitled immediately prior to such event under clause (b) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of shares of GTR Stock outstanding immediately
after such event and the denominator of which is the number of shares of GTR
Stock that were outstanding immediately prior to such event.

                           (B) The Corporation shall declare a dividend or
distribution on the Series B Preferred Stock as provided in Section
IV.H.2(c)(1)(A) immediately after it declares a dividend or distribution on any
shares of GTR Stock (other than a dividend payable in shares of GTR Stock),
provided that, in the event no dividend or distribution shall have been declared
on the GTR Stock during the period between any Quarterly Dividend Payment Date
and the next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per
share on the Series B Preferred Stock shall nevertheless be payable on such
subsequent Quarterly Dividend Payment Date.

                           (C) Dividends shall begin to accrue and be cumulative
on outstanding shares of Series B Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares, unless the date of
issue of such shares is prior to the record date for the first Quarterly
Dividend Payment Date, in which case dividends on such shares shall begin to
accrue from the date of issue of such shares, or unless the date of issue is a
Quarterly Dividend Payment Date or is a date after the record date for the
determination of holders of shares of Series B Preferred Stock entitled to
receive a quarterly dividend and before such Quarterly Dividend Payment Date, in
either of which events such dividends shall begin to accrue and be cumulative
from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall
not bear interest. Dividends paid on the shares of Series B Preferred Stock in
an amount less than the total amount of such dividends at the time accrued and
payable on such shares shall be allocated pro rata on a share-by-share basis
among all such shares at the time outstanding. The Board of Directors may fix a
record date for the determination of holders of shares of Series B Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be not more than 60 days prior to the date
fixed for the payment thereof.

                  (2) VOTING RIGHTS. The holders of shares of Series B Preferred
Stock shall have the following voting rights:

                           (A) Subject to the provision for adjustment
hereinafter set forth, each share of Series B Preferred Stock shall entitle the
holder thereof to 100 times the number of votes to which the holder of each
outstanding share of GTR Stock is then entitled on all matters submitted to a
vote of the stockholders of the Corporation. In the event the Corporation shall
at any time after June 12, 1997 declare or pay any dividend on shares of GTR
Stock payable in


                                       48
<PAGE>

shares of GTR Stock, or effect a subdivision or combination or consolidation of
the outstanding shares of GTR Stock (by reclassification or otherwise than by
payment of a dividend in shares of GTR Stock) into a greater or lesser number of
shares of GTR Stock, then in each such case the number of votes per share to
which holders of shares of Series B Preferred Stock were entitled immediately
prior to such event shall be adjusted by multiplying such number by a fraction,
the numerator of which is the number of shares of GTR Stock outstanding
immediately after such event and the denominator of which is the number of
shares of GTR Stock that were outstanding immediately prior to such event.

                           (B) Except as otherwise provided herein, in the
Articles of Organization, in any other vote of the Board of Directors of the
Corporation creating a series of Preferred Stock, or by law, the holders of
shares of Series B Preferred Stock and the holders of Common Shares and any
other capital stock of the Corporation having general voting rights shall vote
together as one series on all matters submitted to a vote of stockholders of the
Corporation.

                           (C) Except as set forth herein or as otherwise

Preferred Stock unless, prior thereto, the holders of shares of Series B
Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series B
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 100
times the aggregate amount to be distributed per share to holders of shares of
GTR Stock, or (2) to the holders of shares of stock ranking on a parity (either
as to dividends or upon liquidation, dissolution or winding up) with the Series
B Preferred Stock, except distributions made ratably on the Series B Preferred
Stock and all other such parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up. In the event the Corporation shall at any time after
June 12, 1997 declare or pay any dividend on any shares of GTR Stock payable in
shares of GTR Stock, or effect a subdivision or combination or consolidation of
the outstanding shares of GTR Stock (by reclassification or otherwise than by
payment of a dividend in shares of GTR Stock) into a greater or lesser number of
shares of GTR Stock, then in each such case the aggregate amount to which
holders of shares of Series B Preferred Stock were entitled immediately prior to
such event under the proviso in clause (1) of the preceding sentence shall be
adjusted by multiplying such amount by a fraction, the numerator of which is the
number of shares of GTR Stock outstanding immediately after such event and the

                                       49
<PAGE>

hereinafter set forth) equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of GTR Stock is changed or exchanged. In
the event the Corporation shall at any time after June 12, 1997 declare or pay
any dividend on any shares of GTR Stock payable in shares of GTR Stock, or
effect a subdivision or combination or consolidation of the outstanding shares
of GTR Stock (by reclassification or otherwise than by payment of a dividend in
shares of GTR Stock) into a greater or lesser number of shares of GTR Stock,
then in each such case the amount set forth in the preceding sentence with
respect to the exchange or change of shares of Series B Preferred Stock shall be
adjusted by multiplying such amount by a fraction, the numerator of which is the
number of shares of GTR Stock outstanding immediately after such event and the
denominator of which is the number of shares of GTR Stock that were outstanding
immediately prior to such event.

holders of any shares of any series of Preferred Stock ranking prior and
superior to the Series C Preferred Stock with respect to dividends, the holders
of shares of Series C Preferred Stock, in preference to the holders of Common
Shares, and of any other junior stock, shall be entitled to receive, when, as

equal to the greater of (a) $1.00 or (b) subject to the provision for adjustment
hereinafter set forth, 100 times the aggregate per share amount of all cash
dividends, and 100 times the aggregate per share amount (payable in kind) of all
non-cash dividends or other distributions, other than a dividend on shares of
Genzyme Molecular Oncology Division Common Stock (the "GMO Stock") payable in
shares of GMO Stock or a subdivision of the outstanding shares of GMO Stock (by
reclassification or otherwise), declared on the GMO Stock since the immediately
preceding Quarterly Dividend Payment Date or, with respect to the first
Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series C Preferred Stock. In the event the Corporation
shall at any time after June 12, 1997 declare or pay any dividend on any shares
of GMO Stock payable in shares of GMO Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of GMO Stock (by
reclassification or otherwise than by payment of a dividend in shares of GMO

                           (B) The Corporation shall declare a dividend or
distribution on the Series C Preferred Stock as provided in Section
IV.H.2(d)(1)(A) immediately after it declares a dividend or distribution on any
shares of GMO Stock (other than a dividend payable in shares of GMO Stock),
provided that, in the event no dividend or distribution shall have been declared
on the GMO Stock during the period between any Quarterly Dividend Payment Date
and the next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per
share on the Series C Preferred Stock shall nevertheless be payable on such
subsequent Quarterly Dividend Payment Date.

                           (C) Dividends shall begin to accrue and be cumulative
on outstanding shares of Series C Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares, unless the date of

Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be not more than 60 days prior to the date
fixed for the payment thereof.

                  (2) VOTING RIGHTS. The holders of shares of Series C Preferred
Stock shall have the following voting rights:

                           (A) Subject to the provision for adjustment
hereinafter set forth, each share of Series C Preferred Stock shall entitle the
holder thereof to 100 times the number of votes to which the holder of each
outstanding share of GMO Stock is then entitled on all matters submitted to a
vote of the stockholders of the Corporation. In the event the Corporation shall
at any time after June 12, 1997 declare or pay any dividend on any shares of GMO
Stock payable in shares of GMO Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of GMO Stock (by reclassification or
otherwise than by payment of a dividend in shares of GMO Stock) into a greater
or lesser number of shares of GMO Stock, then in each such case the number of
votes per share to which holders of shares of Series C Preferred Stock were
entitled immediately prior to such event shall be adjusted by multiplying such
number by a fraction, the numerator of which is the number of shares of GMO
Stock outstanding immediately after such event and the denominator of which is
the number of shares of GMO Stock that were outstanding immediately prior to
such event.

                           (B) Except as otherwise provided herein, in the
Articles of Organization, in any other vote of the Board of Directors of the

<PAGE>

Common Shares and any other capital stock of the Corporation having general
voting rights shall vote together as one series on all matters submitted to a
vote of stockholders of the Corporation.

                           (C) Except as set forth herein or as otherwise

Preferred Stock unless, prior thereto, the holders of shares of Series C
Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series C
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 100
times the aggregate amount to be distributed per share to holders of shares of
GMO Stock, or (2) to the holders of shares of stock ranking on a parity (either
as to dividends or upon liquidation, dissolution or winding up) with the Series
C Preferred Stock, except distributions made ratably on the Series C Preferred
Stock and all other such parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up. In the event the Corporation shall at any time after
June 12, 1997 declare or pay any dividend on any shares of GMO Stock payable in
shares of GMO Stock, or effect a subdivision or combination or consolidation of

shares of GMO Stock, then in each such case the aggregate amount to which
holders of shares of Series C Preferred Stock were entitled immediately prior to
such event under the proviso in clause (1) of the preceding sentence shall be
adjusted by multiplying such amount by a fraction, the numerator of which is the
number of shares of GMO Stock outstanding immediately after such event and the
denominator of which is the number of shares of GMO Stock that were outstanding
immediately prior to such event.

                  (4) CONSOLIDATION, MERGER, ETC. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
Common Shares are exchanged for or changed into other stock or securities, cash
and/or any other property, then in any such case each share of Series C
Preferred Stock shall at the same time be similarly exchanged or changed into an
amount per share (subject to the provision for adjustment hereinafter set forth)
equal to 100 times the aggregate amount of stock, securities, cash and/or any
other property (payable in kind), as the case may be, into which or for which
each share of GMO Stock is changed or exchanged. In the event the Corporation
shall at any time after June 12, 1997 declare or pay any dividend on shares of
GMO Stock payable in shares of GMO Stock, or effect a subdivision or combination
or consolidation of the outstanding shares of GMO Stock (by reclassification or
otherwise than by payment of a dividend in shares of GMO Stock) into a greater
or lesser number of shares of GMO Stock, then in each such case the amount set
forth in the preceding sentence with respect to the exchange or change of shares
of Series C Preferred Stock shall be adjusted by multiplying such amount by a
fraction, the numerator of which is the number of shares of GMO Stock
outstanding immediately after such event and the denominator of which is the
number of shares of GMO Stock that were outstanding immediately prior to such
event.

                           (A) Subject to the prior and superior rights of the
holders of any shares of any series of Preferred Stock ranking prior and
superior to the Series D Preferred Stock with respect to dividends, the holders
of shares of Series D Preferred Stock, in preference to the holders of Common
Shares, and of any other junior stock, shall be entitled to receive, when, as
and if declared by the Board of Directors out of funds legally available for the
purpose, quarterly dividends payable in cash on the first day of March, June,
September and December in each year (each such date being referred to herein as
a "Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend
Payment Date after the first issuance of a share or fraction of a share of
Series D Preferred Stock, in an amount per share (rounded to the nearest cent)
equal to the greater of (a) $1.00 or (b) subject to the provision for adjustment
hereinafter set forth, 100 times the aggregate per share amount of all cash
dividends, and 100 times the aggregate per share amount (payable in kind) of all
non-cash dividends or other distributions, other than a dividend on shares of
Genzyme Surgical Products Division Common Stock (the "GSP Stock") payable in
shares of GSP Stock or a subdivision of the outstanding shares of GSP Stock (by
reclassification or otherwise), declared on the GSP Stock since the immediately
preceding Quarterly Dividend Payment Date or, with respect to the first
Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series D Preferred Stock. In the event the Corporation
shall at any time after May 26, 1999 declare or pay any dividend on any shares
of GSP Stock payable in shares of GSP Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of GSP Stock (by
reclassification or otherwise than by payment of a dividend in shares of GSP
Stock) into a greater or lesser number of shares of GSP Stock, then in each such
case the amount to which holders of shares of Series D Preferred Stock were
entitled immediately prior to such event under clause (b) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of shares of GSP Stock outstanding immediately
after such event and the denominator of which is the number of shares of GSP
Stock that were outstanding immediately prior to such event.

                           (B) The Corporation shall declare a dividend or
distribution on the Series D Preferred Stock as provided in Section
IV.H.2(e)(1)(A) immediately after it declares a dividend or distribution on any
shares of GSP Stock (other than a dividend payable in shares of GSP Stock),
provided that, in the event no dividend or distribution shall have been declared
on the GSP Stock during the period between any Quarterly Dividend Payment Date
and the next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per
share on the Series D Preferred Stock shall nevertheless be payable on such
subsequent Quarterly Dividend Payment Date.

                           (C) Dividends shall begin to accrue and be cumulative
on outstanding shares of Series D Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares, unless the date of
issue of such shares is prior to the record date for the first Quarterly
Dividend Payment Date, in which case dividends on such shares shall begin to
accrue from the date of issue of such shares, or unless the date of issue is a


                                       53
<PAGE>

Quarterly Dividend Payment Date or is a date after the record date for the
determination of holders of shares of Series D Preferred Stock entitled to
receive a quarterly dividend and before such Quarterly Dividend Payment Date, in
either of which events such dividends shall begin to accrue and be cumulative
from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall
not bear interest. Dividends paid on the shares of Series D Preferred Stock in
an amount less than the total amount of such dividends at the time accrued and
payable on such shares shall be allocated pro rata on a share-by-share basis
among all such shares at the time outstanding. The Board of Directors may fix a
record date for the determination of holders of shares of Series D Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be not more than 60 days prior to the date
fixed for the payment thereof.

                  (2) VOTING RIGHTS. The holders of shares of Series D Preferred
Stock shall have the following voting rights:

                           (A) Subject to the provision for adjustment
hereinafter set forth, each share of Series D Preferred Stock shall entitle the
holder thereof to 100 times the number of votes to which the holder of each
outstanding share of GSP Stock is then entitled on all matters submitted to a
vote of the stockholders of the Corporation. In the event the Corporation shall
at any time after May 26, 1999 declare or pay any dividend on any shares of GSP
Stock payable in shares of GSP Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of GSP Stock (by reclassification or
otherwise than by payment of a dividend in shares of GSP Stock) into a greater
or lesser number of shares of GSP Stock, then in each such case the number of
votes per share to which holders of shares of Series D Preferred Stock were
entitled immediately prior to such event shall be adjusted by multiplying such
number by a fraction, the numerator of which is the number of shares of GSP
Stock outstanding immediately after such event and the denominator of which is
the number of shares of GSP Stock that were outstanding immediately prior to
such event.

                           (B) Except as otherwise provided herein, in the
Articles of Organization, in any other vote of the Board of Directors of the
Corporation creating a series of Preferred Stock, or by law, the holders of
shares of Series D Preferred Stock and the holders of Common Shares and any
other capital stock of the Corporation having general voting rights shall vote
together as one series on all matters submitted to a vote of stockholders of the
Corporation.

                           (C) Except as set forth herein or as otherwise
provided by law, holders of Series D Preferred Stock shall have no voting
rights.

                  (3) LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any
liquidation, dissolution or winding up of the Corporation, no distribution shall
be made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Series D
Preferred Stock unless, prior thereto, the holders of shares of Series D
Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series D
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 100
times the aggregate amount to be distributed per share to holders of shares of
GSP Stock, or


                                       54
<PAGE>

(2) to the holders of shares of stock ranking on a parity (either as to
dividends or upon liquidation, dissolution or winding up) with the Series D
Preferred Stock, except distributions made ratably on the Series D Preferred
Stock and all other such parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up. In the event the Corporation shall at any time after
May 26, 1999 declare or pay any dividend on any shares of GSP Stock payable in
shares of GSP Stock, or effect a subdivision or combination or consolidation of
the outstanding shares of GSP Stock (by reclassification or otherwise than by
payment of a dividend in shares of GSP Stock) into a greater or lesser number of
shares of GSP Stock, then in each such case the aggregate amount to which
holders of shares of Series D Preferred Stock were entitled immediately prior to
such event under the proviso in clause (1) of the preceding sentence shall be
adjusted by multiplying such amount by a fraction, the numerator of which is the
number of shares of GSP Stock outstanding immediately after such event and the
denominator of which is the number of shares of GSP Stock that were outstanding
immediately prior to such event.

                  (4) CONSOLIDATION, MERGER, ETC. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
Common Shares are exchanged for or changed into other stock or securities, cash
and/or any other property, then in any such case each share of Series D
Preferred Stock shall at the same time be similarly exchanged or changed into an
amount per share (subject to the provision for adjustment hereinafter set forth)
equal to 100 times the aggregate amount of stock, securities, cash and/or any
other property (payable in kind), as the case may be, into which or for which
each share of GSP Stock is changed or exchanged. In the event the Corporation
shall at any time after May 26, 1999 declare or pay any dividend on shares of
GSP Stock payable in shares of GSP Stock, or effect a subdivision or combination
or consolidation of the outstanding shares of GSP Stock (by reclassification or
otherwise than by payment of a dividend in shares of GSP Stock) into a greater
or lesser number of shares of GSP Stock, then in each such case the amount set
forth in the preceding sentence with respect to the exchange or change of shares
of Series D Preferred Stock shall be adjusted by multiplying such amount by a
fraction, the numerator of which is the number of shares of GSP Stock
outstanding immediately after such event and the denominator of which is the
number of shares of GSP Stock that were outstanding immediately prior to such
event.

         (f) GENERAL PROVISIONS. Except as otherwise specifically provided in a
particular series of Junior Preferred Stock, the following provisions shall
apply to all series of Junior Preferred Stock:

                  (1) CERTAIN RESTRICTIONS.

                           (A) Whenever quarterly dividends or other dividends
or distributions payable on the Junior Preferred Stock are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether
or not declared, on shares of Junior Preferred Stock outstanding shall have been
paid in full, the Corporation shall not:

                                    (i) declare or pay dividends, or make any
other distributions, on any shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Junior
Preferred Stock;


                                       55
<PAGE>

                                    (ii) declare or pay dividends, or make any
other distributions, on any shares of stock ranking on a parity (either as to
dividends or upon liquidation, dissolution or winding up) with the Junior
Preferred Stock, except dividends paid ratably on the Junior Preferred Stock and
all such parity stock on which dividends are payable or in arrears in proportion
to the total amounts to which the holders of all such shares are then entitled;

                                    (iii) redeem or purchase or otherwise
acquire for consideration shares of any stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Junior
Preferred Stock, provided that the Corporation may at any time redeem, purchase
or otherwise acquire shares of any such junior stock in exchange for shares of
any stock of the Corporation ranking junior (either as to dividends or upon
dissolution, liquidation or winding up) to the Junior Preferred Stock; or

                                    (iv) redeem, purchase or otherwise acquire
for consideration any shares of Junior Preferred Stock, or any shares of stock
ranking on a parity with the Junior Preferred Stock, except in accordance with a
purchase offer made in writing or by publication (as determined by the Board of
Directors) to all holders of such shares upon such terms as the Board of
Directors, after consideration of the respective annual dividend rates and other
relative rights and preferences of the respective series and classes, shall
determine in good faith will result in fair and equitable treatment among the
respective series or classes.

                           (2) The Corporation shall not permit any subsidiary
of the Corporation to purchase or otherwise acquire for consideration any shares
of stock of the Corporation unless the Corporation could, under Section
IV.H.2(f)(1)(A) purchase or otherwise acquire such shares at such time and in
such manner.

         (g) REACQUIRED SHARES. Any shares of Junior Preferred Stock purchased
or otherwise acquired by the Corporation in any manner whatsoever shall be
retired and cancelled promptly after the acquisition thereof. All such shares
shall upon their cancellation become authorized but unissued shares of Preferred
Stock and may be reissued as shares of the same series of Preferred Stock or as
part of a new series of Preferred Stock, subject to the conditions and
restrictions on issuance set forth herein, in the Articles of Organization, in
any other vote of the Board of Directors of the Corporation creating a series of
Preferred Stock, or as otherwise required by law.

         (h) REDEMPTION. The shares of Junior Preferred Stock shall not be
redeemable.

         (i) RANK. The Series A Preferred Stock, the Series B Preferred Stock,
the Series C Preferred Stock and the Series D Preferred Stock shall rank equally
with respect to the payment of dividends and the distribution of assets together
with any other series of the Corporation's Preferred Stock that specifically
provide that they shall rank equally with Junior Preferred Stock. The Junior
Preferred Stock shall rank junior with respect to the payment of dividends and
the distribution of assets to all series of the Corporation's Preferred Stock
that specifically provide that they shall rank prior to the Junior Preferred
Stock. Nothing herein shall preclude the Board from creating any series of
Preferred Stock ranking on a parity with or prior to the Junior Preferred Stock
as to the payment of dividends or the distribution of assets.


                                       56
<PAGE>

         (j) AMENDMENT. The Articles of Organization of the Corporation shall
not be amended in any manner which would materially alter or change the powers,
preferences or special rights of the holders of Junior Preferred Stock so as to
affect them adversely without the affirmative vote of the holders of at least
two-thirds of each outstanding series of Junior Preferred Stock, voting together
as a single series, provided that, any two or more series of Junior Preferred
Stock that are adversely affected in the same manner shall vote together as a
single class.

         (k) FRACTIONAL SHARES. The Junior Preferred Stock may be issued in
fractions of a share which shall entitle the holder, in proportion to such
holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of the Junior Preferred Stock.

                                   ARTICLE VI

                                   ARTICLE VI

                             OTHER LAWFUL PROVISIONS

I.       BOARD OF DIRECTORS

         1. CLASSIFICATION. The directors shall be divided into three classes,
as nearly equal in number as the then total number of directors constituting the
entire Board permits, with the term of office of one class expiring each year.
The initial directors of all classes shall be elected by the incorporator and
shall serve until their respective successors shall be elected and shall
qualify. Thereafter, the directors of the first class shall be elected to hold
office for a term expiring at the first annual meeting of stockholders, the
directors of the second class shall be elected to hold office for a term
expiring at the second annual meeting of stockholders and the directors of the
third class shall be elected to hold office for a term expiring at the third
annual meeting of stockholders. At each annual meeting of stockholders,
successors to the class of directors whose term expires at that meeting shall be
elected for a term expiring at the third annual meeting following their election
and until their successors shall be elected and qualified, subject to prior
death, resignation, retirement or removal. If the number of directors is
changed, any increase or decrease shall be apportioned among the classes so as
to maintain the number of directors in each class as nearly equal as possible,
but in no event will a decrease in the number of directors shorten the term of
any incumbent director. Notwithstanding the foregoing, and except as otherwise
required by law, whenever the holders of any one or more series of Preferred
Stock shall have the right, voting separately as a class, to elect one or more
directors of the Corporation, the election, terms of office and other features
of such directorships shall be governed by the terms of the vote establishing
such series, and such directors so elected shall not be divided into classes
pursuant to this Article VI unless express provided by such terms.

         2. VACANCIES. Except as otherwise determined by the Board of Directors
in establishing a series of Preferred Stock as to directors elected by holders
of such series, any vacancies in the Board of Directors, including a vacancy
resulting from the enlargement of the Board, may be filled by the directors then
in office, though less than a quorum. Each director so chosen to fill a vacancy
shall be elected to complete the term of office of the director who is being
succeeded. In the case of any election of a new director to fill a directorship
created by an enlargement of the Board, the Board shall in such election assign
the class of directors to which such additional director is being elected, and
each director so elected shall hold office for the same term as the other
members of the class to which the director is assigned.

         3. REMOVAL. Except as otherwise determined by the Board of Directors in
establishing a series of Preferred Stock as to directors elected by holders of
such series, at any special meeting of the stockholders called at least in part
for the purpose, any director or directors may, by the affirmative vote of the
holders of at least a majority of the stock entitled to vote for the election of
directors, be removed from office for cause. The provisions of this subsection
shall be the exclusive method for the removal of directors.


                                       59
<PAGE>

J.       STOCKHOLDER VOTE REQUIRED FOR CERTAIN ACTIONS

         The Corporation, by vote of a majority in interest of the stock
outstanding and entitled to vote thereon may (i) authorize any amendment to
these Articles of Organization, (ii) authorize the sale, lease or exchange of
all or substantially all of the Corporation's property and assets, including its
goodwill and (iii) approve a merger or consolidation of the Corporation with or
into any other corporation; so long as such amendment, sale, lease, exchange,
merger or consolidation shall have been approved by the Board of Directors.

K.       ADDITIONAL PROVISIONS

         1. Meetings of the stockholders may be held anywhere within the United
State.

         2. No contract or other transaction of this corporation with any other
person, corporation, association, or partnership shall be affected or
invalidated by the fact that (i) this corporation is a stockholder or partner in
such other corporation, association, or partnership, or (ii) any one or more of
the officers or directors of this corporation is an officer, director or partner
of such other corporation, association or partnership, or (iii) any officer or
director of this corporation, individually or jointly with others, is a party to
or is interested in such contract or transaction. Any director of this
corporation may be counted in determining the existence of a quorum at any
meeting of the board of directors for the purpose of authorizing or ratifying
any such contract or transaction, and may vote thereon, with like force and
effect as if he were not so interested or were not an officer, director, or
partner of such other corporation, association, or partnership.

         3. The corporation may be a partner in any business enterprise which it
would have power to conduct itself.

         4. The by-laws may provide that the directors may make, amend, or
repeal the by-laws in whole or in part, except with respect to any provision
thereof which by law, these Articles of Organization, or the by-laws requires
action by the stockholders.

         5. A director shall not be liable to the corporation or its
stockholders for monetary damages for any breach of fiduciary duty as a
director, except to the extent that the elimination or limitation of liability
is not permitted under the Massachusetts Business Corporation Law as in effect
when such liability is determined. No amendment or repeal of this provision
shall deprive a director of the benefits hereof with respect to any act or
omission occurring prior to such amendment or repeal.

         6. Except as otherwise required by law, any action required or
permitted to be taken by the stockholders of the Corporation must be taken at a
duly called annual or special meeting of such holders and may not be taken by
any consent in writing by such holders.
