                         CERTIFICATE OF INCORPORATION OF
                           SCHERING-PLOUGH CORPORATION


                  Pursuant to Section 14A:7-2(4) of the New Jersey Business
Corporation Act (the "NJBCA"), the undersigned certifies as follows:

                  1. The name of the corporation is Schering-Plough Corporation
(the "CORPORATION").

                  2. The Certificate of Incorporation of the Corporation, as
amended (the "CERTIFICATE OF INCORPORATION"), is hereby amended so that the
designation and number of shares of the class and series acted upon in the
following resolution, and the relative rights, preferences and limitations of
such class and series, are as stated in such resolution.

                  3. The following resolution was duly adopted in accordance
with the August 2, 2004 unanimous written consent of a duly authorized committee
of the Board of Directors of the Corporation , as required by Subsection
14A:-7-2(3) of the NJBCA:

                  RESOLVED, that pursuant to the authority granted to and vested
in the Board of Directors of the Corporation (the "BOARD") in accordance with
the provisions of Article Fourth of its Certificate of Incorporation, the Board
has directed the Corporation to and the Corporation hereby amends the Article
Fourth of the Certificate of Incorporation to add a new subsection (d) and Annex
A to the Certificate of Incorporation in order to create a new series of
Preferred Shares of the Corporation (the "PREFERRED STOCK") and hereby
authorizes and designates such new series of Preferred Stock and fixes the
designations, voting powers, preferences, rights, qualifications, limitations
and restrictions thereof as herein set forth:

                  "(d) Pursuant to the authority conferred by this Article
Fourth, the following series of Preferred Shares has been designated with such
series consisting of the number of shares, with such designations, voting
powers, preferences, rights, qualifications, limitations and restrictions as are
stated in Annex A attached hereto and incorporated herein by reference:

                  Annex A  6.00% Mandatory Convertible Preferred Stock"

                                     ANNEX A

     (1)  Designation  and Amount.  This  series of  Preferred  Shares  shall be
designated as "6.00% Mandatory  Convertible  Preferred Stock" (the  "CONVERTIBLE
PREFERRED  STOCK") and the number of shares  constituting  such series  shall be
28,750,000, with a par value of $1.00 per share.

     (2) Ranking.  The Convertible  Preferred Stock shall rank, as to payment of
dividends and distribution of assets upon dissolution, liquidation or winding up
of the  Corporation,  (a)  senior to (i) the  Common  Stock,  (ii) the  Series A
Preferred  Stock and (iii) any


class or series of capital  stock issued by the  Corporation  which by its terms
ranks  junior to the  Convertible  Preferred  Stock  (collectively,  the "JUNIOR
SECURITIES"),  (b) junior to any class or series of capital  stock issued by the
Corporation  which by its terms ranks senior to the Convertible  Preferred Stock
(the "SENIOR SECURITIES"),  and (c) PARI PASSU with any other class or series of
capital stock issued by the Corporation (the "PARITY SECURITIES"), in each case,
whether now outstanding or to be issued in the future.

     (3) Dividends.  (a) Dividends on the  Convertible  Preferred  Stock will be
payable  quarterly  when, as and if declared by the Board,  or a duly authorized
committee  thereof,  when the Corporation is legally permitted to do so, on each
Dividend  Payment  Date,  at the  annual  rate of $3.00 per  share,  subject  to
adjustment  as  provided  for in Section  18(c).  The  initial  dividend  on the
Convertible  Preferred  Stock for the first Dividend  Period,  commencing on the
date of first issuance of the  Convertible  Preferred  Stock (assuming a date of
first issuance of August 10, 2004), to but excluding  December 15, 2004, will be
$1.0417 per share, and when, as and if declared, will be payable on December 15,
2004,  PROVIDED that the Corporation is legally  permitted to pay such dividends
at such time. Each subsequent  quarterly  dividend on the Convertible  Preferred
Stock, when, as and if declared,  will be $0.75 per share, subject to adjustment
as provided for in Section 18(c).  Dividends payable,  when, as and if declared,
on a Dividend  Payment Date will be payable to Record Holders for the applicable
Dividend Payment Date, except as otherwise provided in Section 6(a).

     (b) The amount of dividends payable on each share of Convertible  Preferred
Stock for each full  quarterly  period will be  computed by dividing  the annual
dividend rate by four. The amount of dividends payable for any other period that
is shorter or longer than a full quarterly  dividend  period will be computed on
the basis of a 360-day year consisting of twelve 30-day months. Dividends on the
Convertible  Preferred Stock shall accrue and cumulate if the Corporation  fails
to declare  one or more  dividends  on the  Convertible  Preferred  Stock in any
amount,  whether or not the  Corporation  is then legally  permitted to pay such
dividends.

     (c) No  interest  or sum of money in lieu of  interest  shall be payable in
respect of any  dividend  not paid on a Dividend  Payment Date or any other late
payment. The Corporation will also not pay Holders of the Convertible  Preferred
Stock any dividend in excess of the full dividends on the Convertible  Preferred
Stock that are payable as described above.

     (d) Dividends in arrears on the  Convertible  Preferred  Stock not declared
for payment or not paid on any  Dividend  Payment  Date may later be declared by
the Board, or a duly authorized committee thereof, and paid on any date fixed by
the Board, or a duly  authorized  committee  thereof,  whether or not a Dividend
Payment Date,  to the Holders of record as they appear on the stock  register of
the  Corporation  on a record date selected by the Board,  or a duly  authorized
committee  thereof,  which  shall  (i) not  precede  the date the  Board,  or an
authorized committee thereof, declares the dividend payable and (ii) not be more
than 60 days prior to the date the dividend is paid.

     (4) Payment  Restrictions.  (a) Unless all  accrued,  cumulated  and unpaid
dividends on the Convertible Preferred Stock for all prior Dividend Periods have
been paid, the Corporation may not:

                                       2



          (i) declare or pay any dividend or make any  distribution of assets on
     any Junior Securities, other than dividends or distributions in the form of
     Junior  Securities  and  cash  solely  in  lieu  of  fractional  shares  in
     connection with any such dividend or distribution;

          (ii) redeem,  purchase or otherwise  acquire any Junior  Securities or
     pay or make any  monies  available  for a  sinking  fund  for  such  Junior
     Securities,  other than (A) upon  conversion  or exchange  for other Junior
     Securities,  (B)  redemptions or purchases of any Series A Preferred  Stock
     purchase  rights or (C) the purchase of  fractional  interests in shares of
     any Junior Securities  pursuant to the conversion or exchange provisions of
     such Junior Securities; or

          (iii)  redeem,  purchase or otherwise  acquire any Parity  Securities,
     except upon  conversion  into or exchange  for other Parity  Securities  or
     Junior  Securities  and  cash  solely  in  lieu  of  fractional  shares  in
     connection with any such conversion or exchange, PROVIDED, HOWEVER, that in
     the  case  of  a  redemption,  purchase  or  other  acquisition  of  Parity
     Securities upon conversion into or exchange for other Parity Securities (A)
     the  aggregate  amount of the  liquidation  preference of such other Parity
     Securities  does  not  exceed  the  aggregate  amount  of  the  liquidation
     preference,  plus accrued,  cumulated and unpaid  dividends,  of the Parity
     Securities  that are  converted  into or  exchanged  for such other  Parity
     Securities,  (B) the  aggregate  number of shares of Common Stock  issuable
     upon  conversion,  redemption  or exchange of such other Parity  Securities
     does not exceed the  aggregate  number of shares of Common  Stock  issuable
     upon conversion,  redemption or exchange of the Parity  Securities that are
     converted  into or exchanged for such other Parity  Securities and (C) such
     other Parity Securities  contain terms and conditions  (including,  without
     limitation,  with  respect to the  payment of  dividends,  dividend  rates,
     liquidation   preferences,   voting  and  representation   rights,  payment
     restrictions,  anti-dilution rights,  change of control rights,  covenants,
     remedies and conversion and redemption rights) that are not materially less
     favorable,  taken as a whole,  to the  Corporation  or the  Holders  of the
     Convertible  Preferred Stock than those contained in the Parity  Securities
     that are converted or exchanged for such other Parity Securities.

     (5) Voting Rights. (a) Except as otherwise required by law, the Certificate
of  Incorporation  or set forth in this  Section 5,  Holders of the  Convertible
Preferred  Stock are not entitled to any voting  rights and their  consent shall
not be required for the taking of any corporate action.

     (b) So long as any shares of Convertible  Preferred Stock are  outstanding,
the  Corporation  will not,  without  the  approval  of the  Holders of at least
two-thirds of the shares of Convertible Preferred Stock then outstanding,  given
in person or by proxy either at an annual meeting or at a special meeting called
for that purpose, at which the Holders of the Convertible  Preferred Stock shall
vote  separately  as  a  single  class,  amend,  alter  or  repeal  (by  merger,
consolidation, combination, reclassification or otherwise) any of the provisions
of the Corporation's  Certificate of Incorporation so as to affect adversely the
rights, preferences or voting powers of the Holders of the Convertible Preferred
Stock;  PROVIDED that any  amendment of the  provisions  of the  Certificate  of
Incorporation so as to issue, authorize or increase the authorized amount of, or
issue or authorize any obligation or security  convertible  into or


                                       3


evidencing a right to purchase, any Parity Securities or Junior Securities shall
be deemed not to affect  adversely the rights,  preferences  or voting powers of
the Holders of the Convertible Preferred Stock. Notwithstanding anything in this
Section 5 to the  contrary,  any  amendment,  alteration or repeal of any of the
provisions  of the  Corporation's  Certificate  of  Incorporation  occurring  in
connection  with any  merger or  consolidation  of the  Corporation  of the type
described in Section  14(e)(i) or any  statutory  exchange of  securities of the
Corporation  with  another  Person  (other than in  connection  with a merger or
acquisition)  of the type described in Section  14(e)(iv) shall be deemed not to
adversely  affect the rights,  preferences or voting power of the Holders of the
Convertible  Preferred Stock, PROVIDED that, subject to Section 10, in the event
the Corporation does not survive the transaction,  the shares of the Convertible
Preferred Stock will become shares of the successor Person, having in respect of
such  successor  Person the same  rights,  preferences  or voting  powers of the
Holders of the Convertible Preferred Stock immediately prior to the consummation
of such merger,  consolidation,  or statutory  exchange and shall be convertible
into  the kind  and  amount  of net  cash,  securities  and  other  property  as
determined  in  accordance  with Section  14(e)  hereof,  PROVIDED  FURTHER that
following any such merger,  consolidation or statutory exchange,  such successor
Person  shall  succeed to and be  substituted  for,  and may exercise all of the
rights and powers of the Corporation under the Convertible Preferred Stock.

     (c) If at any time dividends on the then-outstanding  shares of Convertible
Preferred  Stock or any other class or series of  Preferred  Shares in an amount
equivalent to six quarterly  dividends,  whether or not  consecutive,  shall not
have been (i) paid or (ii)(A)  declared and (B) a sum sufficient for the payment
thereof set aside,  the holders of Preferred  Shares  (including the Convertible
Preferred  Stock),  voting  separately as a single  class,  shall be entitled to
increase the  authorized  number of directors on the Board by two and elect such
two directors (the  "PREFERRED  STOCK  DIRECTORS") at the next annual or special
meeting of the  shareholders  called in the manner  described below. At any such
annual or special meeting of the shareholders,  or any adjournment  thereof,  if
the holders of at least a majority  of the  Preferred  Shares  then  outstanding
shall be present or represented by proxy, then, (1) by vote of the holders of at
least a majority of the Preferred Shares,  voting as a class, then present or so
represented,  the  authorized  number of directors of the  Corporation  shall be
increased by two, and (2) at such meeting the holders of the  Preferred  Shares,
voting as a class,  shall be entitled to elect the Preferred  Stock Directors by
vote of the holders of at least a majority of the Preferred  Shares then present
or so  represented.  Such right of the holders of the Preferred  Shares to elect
the Preferred Stock Directors may be exercised until all dividends in default on
such Preferred  Shares shall have been (i) paid in full or (ii)(A)  declared and
(B) a sum sufficient for the payment thereof set aside. When so paid or provided
for,  (i) the right of the holders of  Preferred  Shares to elect the  Preferred
Stock  Directors  shall  cease,  (ii) the  terms of all of the  Preferred  Stock
Directors shall  terminate at the next annual meeting,  and (iii) the authorized
number of directors of the Corporation shall be reduced  accordingly.  Not later
than 40 days after such  entitlement  arises,  the Board will  convene a special
meeting of the holders of Preferred  Shares for the above purpose.  If the Board
fails to convene such meeting within such 40-day  period,  the holders of 10% of
the outstanding Preferred Shares, considered as a single class, will be entitled
to convene  such meeting to elect the initial  Preferred  Stock  Directors.  Any
director  who shall have been  elected by the holders of  Preferred  Shares as a
class  pursuant to this Section  5(c) may be removed at any time,  either for or
without cause by, and only by, the affirmative  vote of the holders of record of
a majority of the  outstanding  Preferred  Shares given at a special  meeting of


                                       4


such  shareholders  called for such purpose by the  Corporation or at the annual
meeting of  shareholders,  and any vacancy  created by such  removal may also be
filled at such  meeting.  Any vacancy  caused by the death or  resignation  of a
director  who shall have been  elected by the holders of  Preferred  Shares as a
class  pursuant  to this  Section  5(c) may be  filled  only by the  holders  of
outstanding  Preferred  Shares  at a  meeting  called  for such  purpose  by the
Corporation.  The provisions of the Certificate of Incorporation  and By-laws of
the  Corporation  relating to the convening  and conduct of special  meetings of
shareholders  and the  nomination  of  directors  will apply with respect to any
special meeting of the holders of Preferred Shares;  PROVIDED that the notice of
the nomination  need only be delivered to the Secretary of the  Corporation  not
more  than  10  days  after  the  Corporation  (or  the  holders  of  10% of the
outstanding  Preferred  Shares,  if  applicable)  has  notified  the  holders of
Preferred  Shares  of the  date of the  special  meeting  to elect  the  initial
Preferred Stock Directors.

     (d) So long as any of the Convertible  Preferred Stock is outstanding,  the
Corporation will not, without the approval of the Holders of at least two-thirds
of the shares of Convertible  Preferred Stock then  outstanding and any class or
series of Parity Securities then outstanding, voting together as a single class,
given in person or by proxy either at an annual meeting or at a special  meeting
called for that purpose:

          (i) reclassify  any of the  Corporation's  authorized  shares into any
     shares of any class,  or any  obligation  or security  convertible  into or
     evidencing  a  right  to  purchase  such  shares,  ranking  senior  to  the
     Convertible  Preferred  Stock as to payment of dividends or distribution of
     assets upon the dissolution,  liquidation or winding up of the Corporation;
     or

          (ii) issue,  authorize or increase the authorized  amount of, or issue
     or authorize any  obligation or security  convertible  into or evidencing a
     right to purchase,  any stock of any class or series  ranking senior to the
     Convertible  Preferred  Stock as to payment of dividends or distribution of
     assets upon the dissolution,  liquidation or winding up of the Corporation;
     PROVIDED  that  the  Corporation  may  issue,  authorize  or  increase  the
     authorized  amount of, or issue or  authorize  any  obligation  or security
     convertible  into or evidencing a right to purchase,  any shares of capital
     stock ranking on a parity with or junior to the Convertible Preferred Stock
     as to payment of dividends or distribution of assets upon the  dissolution,
     liquidation  or  winding  up of the  Corporation  without  the  vote of the
     Holders of the Convertible Preferred Stock.

     (e) In exercising the voting rights set forth in this Section 5, each share
of Convertible  Preferred Stock shall have one vote per share. In any case where
the Holders of the  Convertible  Preferred Stock are entitled to vote as a class
with  holders  of Parity  Securities  or other  classes  or series of  Preferred
Shares,  each class or series shall have a number of votes  proportionate to the
aggregate liquidation preference of its outstanding shares.

     (6)  Liquidation,  Dissolution  or  Winding  Up.  (a) In the  event  of any
voluntary  or  involuntary  liquidation,   dissolution  or  winding  up  of  the
Corporation,  subject to the rights of holders of any shares of capital stock of
the  Corporation  then  outstanding  ranking  senior to or pari  passu  with the
Convertible  Preferred  Stock in  respect  of  distributions  upon  liquidation,
dissolution or winding up of the Corporation and before any amount shall be paid
or  distributed

                                       5


with respect to holders of any shares of capital stock of the  Corporation  then
outstanding  ranking  junior to the  Convertible  Preferred  Stock in respect of
distributions  upon  liquidation,  dissolution or winding up of the Corporation,
the Holders of the Convertible  Preferred Stock at the time  outstanding will be
entitled to receive,  out of the net assets of the Corporation legally available
for  distribution to shareholders,  a liquidating  distribution in the amount of
$50.00 per share,  subject to adjustment as provided for in Section 18(c),  plus
an amount  equal to the sum of all  accrued,  cumulated  and  unpaid  dividends,
whether or not declared,  for the portion of the  then-current  Dividend  Period
until the payment date and all prior Dividend  Periods and such Holders shall be
deemed to be the  Holders  of  record  for such  Dividend  Periods  or  portions
thereof.  After the payment to the Holders of the Convertible Preferred Stock of
the  full  amounts  provided  for in  this  Section  6(a),  the  Holders  of the
Convertible  Preferred  Stock  will  have  no  right  or  claim  to  any  of the
Corporation's remaining assets.

     (b) For the  purpose  of  this  Section  6,  none  of the  following  shall
constitute  or be deemed to constitute a voluntary or  involuntary  liquidation,
dissolution or winding up of the Corporation:

          (i) the sale,  transfer,  lease or conveyance of all or  substantially
     all of the Corporation's property or business;

          (ii) the  consolidation  or merger of the Corporation with or into any
     other Person; or

          (iii) the consolidation or merger of any other Person with or into the
     Corporation.

     (c) If, upon any  voluntary  or  involuntary  liquidation,  dissolution  or
winding  up of  the  Corporation,  the  amounts  payable  with  respect  to  the
Convertible Preferred Stock then outstanding are not paid in full as provided in
Section 6(a) hereof, no distribution  shall be made on account of any securities
ranking pari passu with the Convertible  Preferred Stock as to the  distribution
of assets upon such  liquidation,  dissolution  or winding up, unless a pro rata
distribution  is made on the  Convertible  Preferred  Stock.  The Holders of the
Convertible  Preferred  Stock  then  outstanding  and the  holders  of any  such
securities then  outstanding  shall share ratably in any  distribution of assets
upon such  liquidation,  dissolution or winding up. The amount allocable to each
series of such  securities then  outstanding  will be based on the proportion of
their  full  respective  liquidation  preference  to the  aggregate  liquidation
preference of the outstanding shares of each such series.

     (d) Written notice of any voluntary or involuntary liquidation, dissolution
or winding up of the  Corporation,  stating the payment date or dates when,  and
the place or places where,  the amounts  distributable to holders of Convertible
Preferred  Stock  in such  circumstances  shall  be  payable,  shall be given by
first-class  mail,  postage  prepaid,  mailed not less than twenty calendar days
prior  to any  payment  date  stated  therein,  to the  Holders  of  Convertible
Preferred  Stock,  at the address shown on the books of the  Corporation  or the
Transfer  Agent;  PROVIDED,  HOWEVER,  that a failure to give notice as provided
above or any  defect  therein  shall not  affect  the  Corporation's  ability to
consummate a voluntary or involuntary liquidation,  dissolution or winding up of
the Corporation.

                                       6


     (7) Mandatory  Conversion on the Mandatory  Conversion Date. (a) Each share
of Convertible  Preferred Stock will  automatically  convert (unless  previously
converted  at the  option of the  Holder in  accordance  with  Section 8 hereof,
converted  at the  option of the  Corporation  pursuant  to  Section 9 hereof or
pursuant to an exercise of a Merger Early  Conversion  right pursuant to Section
10 hereof) on the Mandatory  Conversion  Date, into a number of shares of Common
Stock equal to the Conversion Rate.

     (b) The "CONVERSION RATE" shall be as follows:

          (i) if the Applicable  Market Value of the Common Stock is equal to or
     greater  than  $22.27  (the  "THRESHOLD   APPRECIATION  PRICE"),  then  the
     Conversion  Rate shall be equal to 2.2451  shares of Common Stock per share
     of Convertible  Preferred Stock (the "MINIMUM  CONVERSION RATE"),  which is
     equal to $50.00 divided by the Threshold Appreciation Price);

          (ii) if the  Applicable  Market Value of the Common Stock is less than
     the  Threshold  Appreciation  Price but greater  than $17.96 (the  "INITIAL
     PRICE"),  then the Conversion  Rate shall be equal to $50.00 divided by the
     Applicable Market Value of the Common Stock;

          (iii) if the Applicable  Market Value of the Common Stock is less than
     or equal to the Initial Price,  then the Conversion  Rate shall be equal to
     2.7840 shares of Common Stock per share of Convertible Preferred Stock (the
     "MAXIMUM CONVERSION RATE"), which is equal to $50.00 divided by the Initial
     Price; and

          (iv) the Minimum  Conversion  Rate, the Maximum  Conversion  Rate, the
     Threshold  Appreciation  Price and the  Initial  Price are each  subject to
     adjustment in accordance with the provisions of Section 14 hereof.

     (c) The Holders of Convertible  Preferred Stock on the Mandatory Conversion
Date shall  have the right to  receive  an amount in cash equal to all  accrued,
cumulated and unpaid dividends on the Convertible  Preferred  Stock,  whether or
not declared prior to that date, for the then current  Dividend Period until the
Mandatory  Conversion Date and all prior Dividend Periods (other than previously
declared  dividends on the  Convertible  Preferred  Stock  payable to Holders of
record as of a prior date),  PROVIDED that the Corporation is legally  permitted
to pay such dividends at such time.

     (8)  Early  Conversion  at the  Option  of the  Holder.  (a)  Shares of the
Convertible  Preferred Stock are convertible,  in whole or in part at the option
of the Holder thereof  ("EARLY  CONVERSION")  at any time prior to the Mandatory
Conversion  Date,  into shares of Common Stock at the Minimum  Conversion  Rate,
subject to adjustment as set forth in Section 14 hereof.

     (b) Any written notice of conversion  pursuant to Section 8 hereof shall be
duly executed by the Holder, and specify:

          (i)  the  number  of  shares  of  Convertible  Preferred  Stock  to be
     converted;

                                       7


          (ii) the  name(s) in which such  Holder  desires  the shares of Common
     Stock issuable upon  conversion to be registered and whether such shares of
     Common Stock are to be issued in book-entry or  certificated  form (subject
     to  compliance   with  applicable   legal   requirements  if  any  of  such
     certificates are to be issued in a name other than the name of the Holder);

          (iii) if  certificates  are to be  issued,  the  address to which such
     Holder  wishes  delivery to be made of such new  certificates  to be issued
     upon such conversion; and

          (iv)  any  other   transfer   forms,   tax  forms  or  other  relevant
     documentation  required and specified by the Transfer  Agent, if necessary,
     to effect the conversion.

     (c) If specified by the Holder in the notice of  conversion  that shares of
Common Stock issuable upon conversion of the  Convertible  Preferred Stock shall
be  issued  to a person  other  than  the  Holder  surrendering  the  shares  of
Convertible Preferred Stock being converted, the Holder shall pay or cause to be
paid any  transfer or similar  taxes  payable in  connection  with the shares of
Common Stock so issued.

     (d) Upon receipt by the  Transfer  Agent of a completed  and duly  executed
notice of conversion as set forth in Section 8(b), compliance with Section 8(c),
if  applicable,  and upon  surrender of a certificate  representing  share(s) of
Convertible  Preferred Stock to be converted (if held in certificated form), the
Corporation shall, within three Business Days or as soon as possible thereafter,
issue and shall  instruct the Transfer Agent to register the number of shares of
Common  Stock to which such Holder  shall be  entitled  upon  conversion  in the
name(s) specified by such Holder in the notice of conversion. If a Holder elects
to hold its shares of Common Stock issuable upon  conversion of the  Convertible
Preferred  Stock in certificated  form, the  Corporation  shall promptly send or
cause to be sent,  by hand  delivery  (with  receipt to be  acknowledged)  or by
first-class  mail,  postage  prepaid,  to the  Holder  thereof,  at the  address
designated by such Holder in the written notice of conversion,  a certificate or
certificates  representing  the  number of shares of Common  Stock to which such
Holder  shall be entitled  upon  conversion.  In the event that there shall have
been   surrendered  a  certificate  or  certificates   representing   shares  of
Convertible  Preferred  Stock,  only  part of  which  are to be  converted,  the
Corporation  shall issue and deliver to such Holder or such Holder's designee in
the manner provided in the immediately  preceding  sentence a new certificate or
certificates  representing  the number of shares of Convertible  Preferred Stock
that shall not have been converted.

     (e) The  issuance  by the  Corporation  of shares of  Common  Stock  upon a
conversion of shares of Convertible Preferred Stock in accordance with the terms
hereof shall be deemed effective  immediately  prior to the close of business on
the day of receipt by the Transfer  Agent of the notice of conversion  and other
documents,  if any, set forth in Section 8(b)  hereof,  compliance  with Section
8(c), if applicable,  and the surrender by such Holder or such Holder's designee
of the  certificate  or  certificates  representing  the  shares of  Convertible
Preferred Stock to be converted (if held in certificated form), duly assigned or
endorsed for transfer to the  Corporation (or accompanied by duly executed stock
powers relating thereto).

     (f) A  Holder  of a share  of  Convertible  Preferred  Stock  on the  Early
Conversion  Date with  respect to such share shall have the right to receive all
accrued,  cumulated


                                       8


and  unpaid  dividends,  whether or not  declared,  for the
portion of the then-current  Dividend Period until the Early Conversion Date and
all prior Dividend  Periods  (other than  previously  declared  dividends on the
Convertible  Preferred  Stock  payable to Holders of record as of a prior date),
PROVIDED that the Corporation is then legally permitted to pay such dividends.
Except as described  above,  upon any  optional  conversion  of the  Convertible
Preferred  Stock,  the Corporation  will make no payment or allowance for unpaid
dividends on the Convertible Preferred Stock.

     (9) Provisional Conversion.  (a) Prior to the Mandatory Conversion Date, if
the  Closing  Price of the  Common  Stock  has  exceeded  150% of the  Threshold
Appreciation  Price  for  at  least  20  Trading  Days  within  a  period  of 30
consecutive  Trading  Days  ending  on the  Trading  Day  prior to the date (the
"PROVISIONAL  CONVERSION  NOTICE  DATE") on which the  Corporation  notifies the
Holders (pursuant to clause (b) below) that it is exercising its option to cause
the conversion of the  Convertible  Preferred  Stock pursuant to this Section 9,
the  Corporation  may, at its option,  cause the conversion of all, but not less
than all, the shares of Convertible Preferred Stock then outstanding into shares
of Common  Stock at the Minimum  Conversion  Rate for each share of  Convertible
Preferred  Stock,  subject  to  adjustment  as set  forth  in  Section  14.  The
Corporation  shall be able to cause  this  conversion  only if, in  addition  to
issuing the Holders  shares of Common  Stock,  the  Corporation  is then legally
permitted  to,  and does,  pay the  Holders  in cash (i) an amount  equal to any
accrued,  cumulated and unpaid dividends on the shares of Convertible  Preferred
Stock then outstanding,  whether or not declared (other than previously declared
dividends on the Convertible  Preferred Stock payable to Holders of record as of
a prior date),  plus (ii) the present  value of all  remaining  future  dividend
payments on the shares of Convertible  Preferred Stock then outstanding  through
and including the Mandatory  Conversion Date. The present value of the remaining
future  dividend  payments  will be computed  using a discount rate equal to the
Treasury Yield.

     (b) A written notice (the "PROVISIONAL CONVERSION NOTICE") shall be sent by
or on behalf of the Corporation,  by first class mail,  postage prepaid,  to the
Holders of record as they appear on the stock register of the Corporation on the
Provisional Conversion Notice Date (i) notifying such Holders of the election of
the  Corporation to convert and of the  Provisional  Conversion Date (as defined
below), which date shall not be less than 30 days nor be more than 60 days after
the  Provisional  Conversion  Notice Date, and (ii) stating the Corporate  Trust
Office of the Transfer Agent at which the shares of Convertible  Preferred Stock
called  for  conversion   shall,   upon   presentation   and  surrender  of  the
certificate(s)  (if such shares are held in certificated  form)  evidencing such
shares, be converted, and the Minimum Conversion Rate to be applied thereto. The
Corporation  shall also issue a press release  containing  such  information and
publish such  information  on its website on the World Wide Web,  PROVIDED  that
failure  to  issue  such  press  release  or  publish  such  information  on the
Corporation's  website shall not act to prevent or delay conversion  pursuant to
this Section 9.

     (c) The Corporation shall deliver to the Transfer Agent irrevocable written
instructions authorizing the Transfer Agent, on behalf and at the expense of the
Corporation,  to cause the  Provisional  Conversion  Notice to be duly mailed as
soon as  practicable  after receipt of such  irrevocable  instructions  from the
Corporation  and in accordance with the above  provisions.  The shares of Common
Stock to be issued upon conversion of the  Convertible  Preferred Stock pursuant
to this  Section 9 and all funds  necessary  for the  payment  in cash of (i) an
amount equal


                                       9


to any accrued,  cumulated  and unpaid  dividends  on the shares of  Convertible
Preferred Stock then outstanding, whether or not declared (other than previously
declared  dividends on the  Convertible  Preferred  Stock  payable to Holders of
record as of a prior date),  plus (ii) the present value of all remaining future
dividend payments on the shares of Convertible  Preferred Stock then outstanding
through and including the Mandatory Conversion Date, shall be deposited with the
Transfer  Agent in trust at least  one  Business  Day  prior to the  Provisional
Conversion  Date,  for the pro rata  benefit  of the  Holders  of record as they
appear on the stock register of the Corporation,  so as to be and continue to be
available therefor.  Neither failure to mail such Provisional  Conversion Notice
to one or more such Holders nor any defect in such Provisional Conversion Notice
shall affect the  sufficiency  of the  proceedings  for  conversion  as to other
Holders.

     (d)  If  a  Provisional   Conversion   Notice  shall  have  been  given  as
hereinbefore provided, then each Holder shall be entitled to all preferences and
relative,  participating,  optional and other  special  rights  accorded by this
Certificate of Amendment  until and including the Provisional  Conversion  Date.
From and after the Provisional Conversion Date, upon delivery by the Corporation
of the Common Stock and payment of the funds to the Transfer  Agent as described
in  paragraph  (c) above,  the  Convertible  Preferred  Stock shall no longer be
deemed  to be  outstanding,  and all  rights  of such  Holders  shall  cease and
terminate,  except the right of the  Holders,  upon  surrender  of  certificates
therefor, to receive Common Stock and any amounts to be paid hereunder.

     (e) The deposit of monies in trust with the Transfer Agent up to the amount
necessary for the Provisional  Conversion  shall be irrevocable  except that the
Corporation shall be entitled to receive from the Transfer Agent the interest or
other  earnings,  if any,  earned on any monies so deposited  in trust,  and the
Holders of the shares  converted  shall have no claim to such  interest or other
earnings,  and any  balance  of  monies  so  deposited  by the  Corporation  and
unclaimed by the Holders  entitled  thereto at the  expiration of two years from
the Provisional  Conversion Date shall be repaid,  together with any interest or
other earnings thereon,  to the Corporation,  and after any such repayment,  the
Holders of the shares entitled to the funds so repaid to the  Corporation  shall
look only to the Corporation for such payment without interest.

     (10) Early  Conversion  Upon Cash  Merger.  (a) In the event of a merger or
consolidation  of the  Corporation of the type described in Section  14(e)(i) in
which  the  Common  Stock  outstanding  immediately  prior  to  such  merger  or
consolidation is exchanged for consideration  consisting of at least 30% cash or
cash  equivalents  (any such event,  a "CASH  MERGER"),  then the Holders of the
Convertible  Preferred  Stock  shall have the right to convert  their  shares of
Convertible  Preferred  Stock prior to the earlier of the  Mandatory  Conversion
Date and the Provisional  Conversion Notice Date,  PROVIDED that the Provisional
Conversion  Date occurs within the period  contemplated  by Section 9(b) hereof,
(such  right of the Holders to convert  their  shares  pursuant to this  Section
10(a) being the "MERGER EARLY CONVERSION") as provided herein.

     (b) On or before the fifth  Business Day after the  consummation  of a Cash
Merger,  the  Corporation  or the  corporation  surviving  the Cash  Merger (the
"SURVIVING  CORPORATION")  or,  at the  request  and  expense  of the  Surviving
Corporation, the Transfer Agent, shall give all Holders notice of the occurrence
of the Cash Merger and of the Merger Early

                                       10



Conversion right arising as a result thereof.  The Surviving  Corporation  shall
also deliver a copy of such notice to the Transfer Agent. Each such notice shall
contain:

          (i) the  date,  which  shall  be not  less  than 20 nor  more  than 35
     calendar  days after the date of such  notice,  on which the  Merger  Early
     Conversion  will be effected (such date being the "MERGER EARLY  CONVERSION
     DATE");

          (ii) the date,  which shall be on, or one  Business  day prior to, the
     Merger Early  Conversion  Date, by which the Merger Early  Conversion right
     must be exercised;

          (iii) the  Conversion  Rate in effect on the Trading  Day  immediately
     preceding such Cash Merger  (calculated  as if the Trading Day  immediately
     preceding such Cash Merger were the Mandatory Conversion Date) and the kind
     and amount of securities,  cash and other property  receivable per share of
     Convertible  Preferred  Stock by the Holder  upon  conversion  of shares of
     Convertible Preferred Stock pursuant to Section 10(d); and

          (iv) the  instructions  a Holder must  follow to  exercise  the Merger
     Early Conversion right.

     (c) To exercise a Merger Early Conversion  right, a Holder shall deliver to
the Transfer  Agent at its  Corporate  Trust Office by 5:00 p.m.,  New York City
time on or before the date by which the Merger  Early  Conversion  right must be
exercised  as specified in the notice,  the  certificate(s)  (if such shares are
held in certificated form) evidencing the shares of Convertible  Preferred Stock
with respect to which the Merger Early Conversion right is being exercised, duly
assigned or endorsed for transfer to the Surviving  Corporation,  or accompanied
by duly executed  stock powers  relating  thereto,  or in blank,  with a written
notice to the Surviving  Corporation  stating the Holder's  intention to convert
early in connection with the Cash Merger containing the information set forth in
Section 8(b) and providing the Surviving Corporation with payment instructions.

     (d) If the Holder  exercises its Merger Early  Conversion right pursuant to
the terms hereof, on the Merger Early Conversion Date the Surviving  Corporation
shall  deliver  or cause to be  delivered  the net  cash,  securities  and other
property  entitled to be  received  by such  exercising  Holder,  determined  by
assuming the Holder had  converted  its shares of  Convertible  Preferred  Stock
immediately  before  the Cash  Merger  at the  Conversion  Rate in effect on the
Trading Day immediately preceding such Cash Merger calculated in accordance with
Section  7(b) hereof and that such Holder was not the  counterparty  to the Cash
Merger or an  affiliate  of such other party and did not  exercise any rights of
election with respect to the kind or amount of consideration to be received.  In
the event a Merger Early Conversion right is exercised by a Holder in accordance
with the terms hereof,  (i) all references  herein to Mandatory  Conversion Date
shall be  deemed to refer to such  Merger  Early  Conversion  Date and (ii) if a
Reorganization  Event  (other  than the Cash  Merger) has  previously  occurred,
"Applicable  Market  Value"  shall be deemed to refer to the  Applicable  Market
Value of the Exchange  Property as determined in accordance  with Section 14(e).
If a Holder  does not  elect to  exercise  the  Merger  Early  Conversion  right
pursuant to this Section 10, in lieu of shares of Common  Stock,  the  Surviving
Corporation  shall deliver to such Holder on the Mandatory  Conversion Date, the
Provisional

                                       11



Conversion Date or an Early Conversion Date, such net cash, securities and other
property as determined in accordance with Section 14(e) hereof.

     (e) Upon a Merger Early Conversion, the Transfer Agent shall, in accordance
with the  instructions  provided  by the Holder  thereof in the  written  notice
provided to the Surviving  Corporation as set forth above, deliver to the Holder
such net cash,  securities  or other  property  issuable  upon such Merger Early
Conversion,  together  with  payment  in lieu of any  fraction  of a  share,  as
provided herein.

     (f) In the event that a Merger Early Conversion is effected with respect to
shares of Convertible  Preferred Stock  representing less than all the shares of
Convertible  Preferred Stock held by a Holder, upon such Merger Early Conversion
the Surviving  Corporation  shall execute and the Transfer  Agent shall,  unless
otherwise instructed in writing,  countersign and deliver to the Holder thereof,
at the expense of the Surviving Corporation, a certificate evidencing the shares
of  Convertible  Preferred  Stock as to which  Merger Early  Conversion  was not
effected.

     (g) In the event that a Merger Early Conversion is effected with respect to
shares of Convertible  Preferred  Stock, the Holder of such shares on the Merger
Early Conversion Date with respect to such share shall have the right to receive
an amount in cash equal to all accrued, cumulated and unpaid dividends,  whether
or not declared  prior to the Merger Early  Conversion  Date, for the portion of
the then-current  Dividend Period until the Merger Early Conversion Date and all
prior  Dividend  Periods  (other  than  previously  declared  dividends  on  the
Convertible  Preferred  Stock  payable to Holders of record as of a prior date),
provided that at such time the Corporation is then legally permitted to pay such
dividends.

     (11) Conversion Procedures.  (a) Upon issuance and delivery to the Transfer
Agent of  certificates  representing  shares of the Common Stock to be delivered
upon  conversion of the shares of Convertible  Preferred  Stock on the Mandatory
Conversion  Date, the Provisional  Conversion  Date, the Merger Early Conversion
Date or any Early Conversion Date (collectively, a "CONVERSION DATE"), dividends
on any shares of  Convertible  Preferred  Stock  converted to Common Stock shall
cease to accrue and cumulate,  and such shares of  Convertible  Preferred  Stock
shall cease to be outstanding,  in each case, subject to the right of Holders of
such shares to receive  any  accrued,  cumulated  and unpaid  dividends  on such
shares to which they are otherwise entitled pursuant to Section (7), (8) or (10)
hereof, as applicable.

     (b) The person or persons  entitled  to receive the Common  Stock  issuable
upon such conversion  shall be treated for all purposes as the record  holder(s)
of such  shares of Common  Stock as of the close of  business  on the  Mandatory
Conversion Date, the Merger Early  Conversion  Date, the Provisional  Conversion
Date or any  Early  Conversion  Date,  as the  case  may  be.  No  allowance  or
adjustment,  except as set forth in  Section  14,  shall be made in  respect  of
dividends  payable to holders of Common  Stock of record as of any date prior to
such  effective  date.  Prior to such  effective  date,  shares of Common  Stock
issuable upon conversion of any shares of Convertible  Preferred Stock shall not
be deemed  outstanding  for any  purpose,  and Holders of shares of  Convertible
Preferred Stock shall have no rights with respect to the Common Stock (including
voting  rights,  rights to  respond to tender  offers  for the Common  Stock


                                       12


and rights to receive any dividends or other  distributions on the Common Stock)
by virtue of holding shares of Convertible Preferred Stock.

     (c) Shares of Convertible Preferred Stock duly converted in accordance with
this Certificate of Amendment, or otherwise reacquired by the Corporation,  will
resume the status of authorized and unissued Preferred Stock, undesignated as to
series and available for future issuance.

     (d) In the event  that a Holder of shares of  Convertible  Preferred  Stock
shall not by written  notice  designate the name in which shares of Common Stock
to be issued upon  conversion of such shares should be registered or the address
to which the  certificate  or  certificates  representing  such shares should be
sent, the Corporation  shall be entitled to register such shares,  and make such
payment, in the name of the Holder of such Convertible  Preferred Stock as shown
on the records of the  Corporation  and to send the  certificate or certificates
representing  such shares to the address of such Holder  shown on the records of
the Corporation.

     (12)  Reservation of Common Stock.  (a) The Corporation  shall at all times
reserve and keep available out of its  authorized  and unissued  Common Stock or
shares held in the treasury of the  Corporation,  solely for  issuance  upon the
conversion of shares of Convertible  Preferred  Stock as herein  provided,  free
from any  preemptive  or other similar  rights,  such number of shares of Common
Stock as shall  from time to time be  issuable  upon the  conversion  of all the
shares of Convertible  Preferred  Stock then  outstanding.  For purposes of this
Section  12(a),  the number of shares of Common Stock that shall be  deliverable
upon the conversion of all  outstanding  shares of Convertible  Preferred  Stock
shall be computed as if at the time of computation all such  outstanding  shares
were held by a single Holder.

     (b)  Notwithstanding  the foregoing,  the Corporation  shall be entitled to
deliver upon  conversion of shares of  Convertible  Preferred  Stock,  as herein
provided,  shares of Common  Stock  reacquired  and held in the  treasury of the
Corporation (in lieu of the issuance of authorized and unissued shares of Common
Stock),  so long as any such  treasury  shares  are free and clear of all liens,
charges, security interests or encumbrances (other than liens, charges, security
interests and other encumbrances created by the Holders).

     (c) All shares of Common Stock delivered upon conversion of the Convertible
Preferred  Stock  shall  be duly  authorized,  validly  issued,  fully  paid and
non-assessable,  free and clear of all liens,  claims,  security  interests  and
other  encumbrances  (other than liens,  charges,  security  interests and other
encumbrances created by the Holders).

     (d) Prior to the delivery of any securities that the  Corporation  shall be
obligated to deliver upon conversion of the  Convertible  Preferred  Stock,  the
Corporation shall use its reasonable best efforts to comply with all federal and
state  laws  and  regulations  thereunder  requiring  the  registration  of such
securities  with, or any approval of or consent to the delivery  thereof by, any
governmental authority.

     (e) The  Corporation  hereby  covenants and agrees that, if at any time the
Common  Stock  shall be  listed  on the New York  Stock  Exchange  or any  other
national  securities  exchange or automated  quotation  system,  the Corporation
will, if permitted by the rules of such

                                       13



exchange or automated  quotation  system,  list and keep listed,  so long as the
Common Stock shall be so listed on such exchange or automated  quotation system,
all Common Stock issuable upon  conversion of the Convertible  Preferred  Stock;
PROVIDED,  HOWEVER,  that if the rules of such  exchange or automated  quotation
system  permit the  Corporation  to defer the listing of such Common Stock until
the first  conversion  of  Convertible  Preferred  Stock  into  Common  Stock in
accordance with the provisions  hereof,  the Corporation  covenants to list such
Common Stock  issuable upon  conversion of the  Convertible  Preferred  Stock in
accordance with the requirements of such exchange or automated  quotation system
at such time.

     (13) Fractional  Shares.  (a) No fractional  shares of Common Stock will be
issued as a result of any conversion of shares of Convertible Preferred Stock.

     (b) In lieu of any fractional  share of Common Stock otherwise  issuable in
respect of any mandatory conversion pursuant to Section 7 hereof, any conversion
at the option of the Corporation pursuant to Section 9 hereof or a conversion at
the option of the  holder  pursuant  to  Section 8 or  Section  10  hereof,  the
Corporation  shall pay an amount in cash (computed to the nearest cent) equal to
the same fraction of:

          (i) in the case of a  conversion  pursuant  to  Section 7 or Section 9
     hereof or a Merger  Early  Conversion  pursuant  to Section 10, the Current
     Market Price; or

          (ii) in the case of an Early Conversion  pursuant to Section 8 hereof,
     the Closing Price of the Common Stock  determined as of the second  Trading
     Day immediately preceding the effective date of conversion.

     (c)  If  more  than  one  share  of  the  Convertible  Preferred  Stock  is
surrendered for conversion at one time by or for the same Holder,  the number of
full shares of Common Stock issuable upon  conversion  thereof shall be computed
on the basis of the  aggregate  number of  shares of the  Convertible  Preferred
Stock so surrendered.

     (14)  Anti-Dilution  Adjustments to the Fixed  Conversion  Rates.  (a) Each
Fixed  Conversion  Rate and the number of shares of Common Stock to be delivered
upon conversion shall be subject to the following adjustments.

          (i) Stock Dividends and  Distributions.  In case the Corporation shall
     pay or make a dividend or other  distribution on the Common Stock in shares
     of Common Stock, each Fixed Conversion Rate, as in effect at the opening of
     business  on the day  following  the date  fixed for the  determination  of
     shareholders entitled to receive such dividend or other distribution, shall
     be increased by dividing such Fixed  Conversion Rate by a fraction of which
     the numerator shall be the number of shares of Common Stock  outstanding at
     the close of  business  on the date  fixed for such  determination  and the
     denominator  shall be the sum of such  number of  shares  of  Common  Stock
     outstanding  and the total  number of shares of Common  Stock  constituting
     such  dividend or other  distribution,  such  increase to become  effective
     immediately  after the opening of business  on the day  following  the date
     fixed for such determination. For the purposes of this sub-section (i), the
     number of shares of Common Stock at the time outstanding  shall not include
     shares held in the treasury of the Corporation but shall include any shares


                                       14


     issuable in respect of any scrip  certificates  issued in lieu of fractions
     of shares of Common  Stock.  The  Corporation  will not pay any dividend or
     make any distribution on shares of Common Stock held in the treasury of the
     Corporation.

          (ii)  Subdivisions,  Splits and  Combinations  of the Common Stock. In
     case outstanding shares of Common Stock shall be subdivided or split into a
     greater  number of shares of Common Stock,  each Fixed  Conversion  Rate in
     effect at the opening of business on the day  following  the day upon which
     such  subdivision  or split  becomes  effective  shall  be  proportionately
     increased,  and,  conversely,  in case  outstanding  shares of Common Stock
     shall each be  combined  into a smaller  number of shares of Common  Stock,
     such Fixed  Conversion Rate in effect at the opening of business on the day
     following the day upon which such  combination  becomes  effective shall be
     proportionately reduced, such increase or reduction, as the case may be, to
     become  effective  immediately  after the  opening of  business  on the day
     following the day upon which such subdivision, split or combination becomes
     effective.

          (iii) Issuance of Stock Purchase Rights. In case the Corporation shall
     issue  rights or warrants to all  holders of its Common  Stock  (other than
     rights or warrants issued pursuant to a dividend reinvestment plan or share
     purchase plan or other similar plans), entitling such holders, for a period
     of up to 45 days from the date of issuance of such rights or  warrants,  to
     subscribe for or purchase  shares of Common Stock at a price per share less
     than the Current  Market Price on the date fixed for the  determination  of
     shareholders  entitled  to  receive  such  rights or  warrants,  each Fixed
     Conversion  Rate in effect at the opening of business on the day  following
     the date fixed for such  determination  shall be increased  by  multiplying
     such Fixed  Conversion Rate by a fraction,  the numerator of which shall be
     the number of shares of Common Stock  outstanding  at the close of business
     on the date  fixed  for such  determination  plus the  number  of shares of
     Common Stock so offered for subscription or purchase and the denominator of
     which  shall be the  number of shares of Common  Stock  outstanding  at the
     close of business on the date fixed for such  determination plus the number
     of shares of Common Stock which the aggregate  offering  price of the total
     number of shares of Common  Stock so offered for  subscription  or purchase
     would  purchase  at such  Current  Market  Price,  such  increase to become
     effective  immediately  after the opening of business on the day  following
     the date fixed for such  determination.  For the  purposes  of this  clause
     (iii), the number of shares of Common Stock at any time  outstanding  shall
     not  include  shares  held in the  treasury  of the  Corporation  but shall
     include any shares issuable in respect of any scrip certificates  issued in
     lieu of  fractions of shares of Common  Stock.  The  Corporation  shall not
     issue any such rights or warrants in respect of shares of Common Stock held
     in the treasury of the Corporation.

          (iv) Debt or Asset Distribution. (A) In case the Corporation shall, by
     dividend  or  otherwise,  distribute  to all  holders of its  Common  Stock
     evidences of its indebtedness, shares of capital stock, securities, cash or
     other assets (excluding any dividend or distribution referred to in Section
     14(a)(i) or Section 14(a)(ii) hereof, any rights or warrants referred to in
     Section 14(a)(iii) hereof, any dividend or distribution paid exclusively in
     cash,  any  consideration  payable in connection  with a tender or exchange
     offer made by the Corporation or any subsidiary of the Corporation, and any
     dividend  of

                                       15



     shares  of  capital  stock  of any  class  or  series,  or  similar  equity
     interests,  of or relating to a subsidiary  or other  business  unit in the
     case of a Spin-Off referred to in Section  14(a)(iv)(B)  below), each Fixed
     Conversion  Rate  shall  be  adjusted  so  that it  shall  equal  the  rate
     determined by multiplying such Fixed Conversion Rate in effect  immediately
     prior to the close of business on the date fixed for the  determination  of
     shareholders  entitled to receive  such  distribution  by a  fraction,  the
     numerator  of which  shall be the  Current  Market  Price  per share of the
     Common Stock on the date fixed for such  determination  and the denominator
     of which shall be such  Current  Market Price per share of the Common Stock
     less  the then  Fair  Market  Value  of the  portion  of the  evidences  of
     indebtedness,  shares of capital stock, securities, cash or other assets so
     distributed  applicable  to one share of Common Stock,  such  adjustment to
     become  effective  immediately  prior to the opening of business on the day
     following the date fixed for the determination of shareholders  entitled to
     receive  such  distribution.  In any case in which this  clause  (iv)(A) is
     applicable, clause (iv)(B) of this Section 14(a) shall not be applicable.

          (B) In the case of a Spin-Off,  each Fixed  Conversion  Rate in effect
     immediately  before  the close of  business  on the  record  date fixed for
     determination of shareholders entitled to receive that distribution will be
     increased by  multiplying  each Fixed  Conversion  Rate by a fraction,  the
     numerator  of which is the  Current  Market  Price per share of the  Common
     Stock plus the Fair Market  Value of the portion of those shares of capital
     stock or similar equity interests so distributed applicable to one share of
     Common Stock and the  denominator  of which is the Current Market Price per
     share of the Common Stock. Any adjustment to the Conversion Rate under this
     clause  (iv)(B) of this  Section  14(a) will occur on the 15th  Trading Day
     from, but excluding, the "ex-date" with respect to the Spin-Off.

          (v) Cash Distributions.  In case the Corporation shall distribute cash
     to all holders of the Common Stock  immediately after the close of business
     on such date for determination, each Fixed Conversion Rate will be adjusted
     by multiplying  such Fixed Conversion Rate in effect  immediately  prior to
     the  close  of  business  on  the  date  fixed  for  determination  of  the
     shareholders of the Corporation  entitled to receive such distribution by a
     fraction,  the  numerator of which will be the Current  Market Price of the
     Common Stock on the date fixed for such  determination  and the denominator
     of which will be the Current  Market  Price of the Common Stock on the date
     fixed for such determination minus the amount per share of such dividend or
     distribution;  PROVIDED,  that no  adjustment  will be made to either Fixed
     Conversion  Rate for (i) any cash that is distributed  in a  Reorganization
     Event to which Section 14(e) applies or as part of a distribution  referred
     to  in  paragraph  (iv)  of  this  Section  14(a),  (ii)  any  dividend  or
     distribution in connection with the liquidation,  dissolution or winding up
     of the  Corporation  (iii) any  consideration  payable in connection with a
     tender or exchange  offer made by the  Corporation or any subsidiary of the
     Corporation  or (iv) any cash  dividends  on the Common Stock to the extent
     that the aggregate  cash dividend per share of Common Stock does not exceed
     (x) $0.055 in any fiscal quarter in the case of a quarterly dividend or (y)
     $0.22 in the prior twelve  months in the case of an annual  dividend  (each
     such number,  the  "DIVIDEND  THRESHOLD  AMOUNT").  The Dividend  Threshold
     Amount is subject to an  inversely  proportional  adjustment  whenever  the
     Fixed  Conversion  Rates are adjusted,  PROVIDED that


                                       16


     no  adjustment  will be  made  to the  Dividend  Threshold  Amount  for any
     adjustment made to the Fixed  Conversion  Rates pursuant to this clause (v)
     or clause (iii), (iv), (vi), (vii) or (viii) of this Section 14(a).

          If an  adjustment  is  required  to be made under this clause (v) as a
     result  of a  distribution  that is a  quarterly  or annual  dividend,  the
     adjustment shall be based upon the amount by which the distribution exceeds
     the applicable  Dividend  Threshold Amount. If an adjustment is required to
     be made  under  this  clause  as a result of a  distribution  that is not a
     quarterly or annual  dividend,  the adjustment shall be based upon the full
     amount of such distribution.

          (vi) Self  Tender  Offers  and  Exchange  Offers.  In case a tender or
     exchange offer made by the Corporation or any subsidiary of the Corporation
     for all or any portion of the Common  Stock shall expire and such tender or
     exchange offer (as amended upon the  expiration  thereof) shall require the
     payment  to  shareholders  (based  on the  acceptance,  up to  any  maximum
     specified in the terms of the tender or exchange offer, of Purchased Shares
     (as defined below in this Section)) of an aggregate consideration per share
     of Common Stock having a Fair Market Value that exceeds the Current  Market
     Price  per  share of the  Common  Stock  on the  seventh  Trading  Day next
     succeeding  the last  date on which  (the  "EXPIRATION  TIME")  tenders  or
     exchanges  could have been made  pursuant to such tender or exchange  offer
     (as it may be amended),  then, and in each such case,  immediately prior to
     the  opening of  business  on the eighth  Trading Day after the date of the
     Expiration  Time, each Fixed  Conversion Rate shall be adjusted so that the
     same shall equal the rate determined by dividing such Fixed Conversion Rate
     in effect  immediately  prior to the  opening  of  business  on the  eighth
     Trading Day after the  Expiration  Time by a fraction (A) the  numerator of
     which shall be equal to (x) the product of (I) the Current Market Price per
     share of the Common Stock on the seventh  Trading Day after the  Expiration
     Time and (II) the number of shares of Common Stock  outstanding  (including
     any shares validly  tendered and not withdrawn) at the Expiration Time less
     (y) the  amount  of cash  plus  the  Fair  Market  Value  of the  aggregate
     consideration  payable  to  shareholders  in the tender or  exchange  offer
     (assuming the acceptance,  up to any maximum  specified in the terms of the
     tender or exchange offer, of Purchased Shares),  and (B) the denominator of
     which  shall be equal to the product of (x) the  Current  Market  Price per
     share of the Common Stock on the seventh  Trading Day after the  Expiration
     Time and (y) the number of shares of Common  Stock  outstanding  (including
     any shares validly  tendered and not  withdrawn) as of the Expiration  Time
     less the number of all shares validly  tendered and not withdrawn as of the
     Expiration  Time (the shares  deemed so accepted,  up to any such  maximum,
     being referred to as the "PURCHASED SHARES").

          (vii) Third  Party  Tender  Offers and  Exchange  Offers.  In case any
     Person other than the  Corporation  or any  subsidiary  of the  Corporation
     makes a payment in respect of a tender offer or exchange offer in which, as
     of the last time (the "OFFER  EXPIRATION  TIME") that  tenders or exchanges
     may be made  pursuant to such  tender or  exchange  offer (as it shall have
     been amended),  the Board of Directors is not recommending rejection of the
     offer,  then each Fixed Conversion Rate will be adjusted by multiplying the
     Fixed Conversion Rate in effect  immediately prior to the close of business
     on the date of the

                                       17


     Offer  Expiration Time by a fraction (A) the numerator of which will be the
     sum of (x) the Fair Market Value of the aggregate  consideration payable to
     all  holders of Common  Stock  based on the  acceptance  (up to any maximum
     specified  in the terms of the  tender  or  exchange  offer) of all  shares
     validly  tendered or exchanged and not withdrawn as of the Offer Expiration
     Time (the shares deemed so accepted, up to any such maximum, being referred
     to as the "ACCEPTED PURCHASED SHARES") and (y) the product of the number of
     shares of Common Stock outstanding less any such Accepted  Purchased Shares
     and the Current Market Price of the Common Stock on the seventh Trading Day
     next succeeding the Offer  Expiration Time and (B) the denominator of which
     will be the  product of the number of shares of Common  Stock  outstanding,
     including any such Accepted  Purchased Shares, and the Current Market Price
     of the Common Stock on the seventh  Trading Day next  succeeding  the Offer
     Expiration  Time. Such adjustment  shall become effective as of the opening
     of business on the eighth Trading Day following the Offer Expiration Time.

          The  adjustment  referred to in this clause (vii) will only be made if
     (1) the tender offer or exchange  offer is for an amount that increases the
     offeror's ownership of common stock to more than 30% of the total shares of
     Common  Stock  outstanding;  and (2) the cash and Fair Market  Value of any
     other  consideration  included  in the  payment  per share of Common  Stock
     exceeds the Current Market Price of the Common Stock on the seventh Trading
     Day next succeeding the Offer Expiration Time.

          However, the adjustment referred to in this clause will not be made if
     as of the Offer Expiration Time, the offering  documents disclose a plan or
     an  intention  to cause the  Corporation  to engage in a  consolidation  or
     merger or a sale of all or substantially all of the  Corporation's  assets.
     In the event the offeror is  obligated to purchase  shares  pursuant to any
     such tender or exchange offer, but such Person is permanently  prevented by
     applicable  law from effecting any such purchases or all such purchases are
     rescinded,  each Fixed  Conversion  Rate shall be  readjusted to what would
     have been in effect if such tender or exchange offer had not been made.

          (viii) Rights Plans.  To the extent that the  Corporation has a rights
     plan in effect on any Conversion  Date,  upon conversion of any Convertible
     Preferred  Stock,  Holders shall receive,  in addition to the Common Stock,
     the rights under such rights plan,  unless,  prior to such Conversion Date,
     the rights have separated  from the Common Stock,  in which case each Fixed
     Conversion  Rate will be adjusted at the time of  separation of such rights
     as if the  Corporation  made a  distribution  to all  holders of the Common
     Stock as described  in clause (iv) above,  subject to  readjustment  in the
     event of the expiration, termination or redemption of such rights.

     (b) Adjustment for Tax Reasons.  The Corporation may make such increases in
each Fixed Conversion Rate, in addition to any other increases  required by this
Section 14, if the Board deems it  advisable to avoid or diminish any income tax
to holders of the Common Stock  resulting from any dividend or  distribution  of
shares (or  issuance of rights or warrants to acquire  shares) or from any event
treated as such for income tax purposes or for any other reasons;  PROVIDED that
the same proportionate adjustment must be made to each Fixed Conversion Rate.

                                       18


     (c) Calculation of Adjustments.  (i) All adjustments to the Conversion Rate
shall be calculated to the nearest  1/10,000th of a share (or, if there is not a
nearest  1/10,000th  of a share,  to the next  lower  1/10,000th  of a share) of
Common  Stock.  Prior to the  Mandatory  Conversion  Date,  no adjustment in the
Conversion  Rate shall be  required  unless  such  adjustment  would  require an
increase  or  decrease  of at least  one  percent  therein;  PROVIDED,  that any
adjustments  which by reason of this  subparagraph  are not  required to be made
shall be carried  forward and taken into account in any  subsequent  adjustment;
PROVIDED  FURTHER that on the  Mandatory  Conversion  Date,  adjustments  to the
Conversion Rate will be made with respect to any such adjustment carried forward
and which has not been taken into account  before such date. If an adjustment is
made  to  the  Conversion  Rate  pursuant  to  Sections   14(a)(i),   14(a)(ii),
14(a)(iii),  14(a)(iv),  14(a)(v), 14(a)(vi),  14(a)(vii) or 14(b), an inversely
proportional  adjustment shall also be made to the Threshold  Appreciation Price
and the Initial Price solely for purposes of  determining  which of clauses (i),
(ii)  and  (iii)  of  Section  7(b)  will  apply on the  Conversion  Date.  Such
adjustment  shall be made by dividing each of the Threshold  Appreciation  Price
and the  Initial  Price by a  fraction,  the  numerator  of  which  shall be the
Conversion Rate immediately after such adjustment pursuant to Sections 14(a)(i),
14(a)(ii), 14(a)(iii), 14(a)(iv), 14(a)(v), 14(a)(vi) or 14(a)(vii) or 14(b) and
the  denominator of which shall be the Conversion Rate  immediately  before such
adjustment; PROVIDED, that if such adjustment to the Conversion Rate is required
to be made  pursuant  to the  occurrence  of any of the events  contemplated  by
Sections 14(a)(i),  14(a)(ii),  14(a)(iii),  14(a)(iv),  14(a)(v),  14(a)(vi) or
14(a)(vii) or 14(b) during the period taken into  consideration  for determining
the Applicable Market Value, appropriate and customary adjustments shall be made
to the Conversion Rate.

     (ii) No  adjustment  to the  Conversion  Rate need be made if  Holders  may
participate in the transaction  that would otherwise give rise to an adjustment,
so long as the  distributed  assets or securities the Holders would receive upon
conversion of the Convertible Preferred Stock, if convertible,  exchangeable, or
exercisable,  are  convertible,  exchangeable  or  exercisable,  as  applicable,
without  any loss of  rights  or  privileges  for a  period  of at least 45 days
following  conversion  of  the  Convertible   Preferred  Stock.  The  applicable
Conversion Rate shall not be adjusted:

          (A) upon the  issuance of any shares of the Common  Stock  pursuant to
     any present or future plan providing for the  reinvestment  of dividends or
     interest  payable on the  Corporation's  securities  and the  investment of
     additional optional amounts in shares of Common Stock under any plan;

          (B) upon the  issuance of any shares of the Common  Stock or rights or
     warrants  to  purchase  those  shares  pursuant  to any  present  or future
     employee,  director or consultant  benefit plan or program of or assumed by
     the Corporation or any of its subsidiaries;

          (C) upon the  issuance of any shares of the Common  Stock  pursuant to
     any option,  warrant,  right or  exercisable,  exchangeable  or convertible
     security  outstanding  as of the date shares of the  Convertible  Preferred
     Stock were first issued;

          (D) for a change in the par value or no par value of the Common Stock;
     or

          (E) for accrued, cumulated and unpaid dividends.

                                       19


          (iii) The Corporation shall have the power to resolve any ambiguity or
     correct  any  error in this  Section  14 and its  action  in so  doing,  as
     evidenced  by a resolution  of the Board,  or a duly  authorized  committee
     thereof, shall be final and conclusive.

     (d) Notice of  Adjustment.  Whenever  each Fixed  Conversion  Rate is to be
adjusted in accordance  with Section 14(a) or (b), the  Corporation  shall:  (i)
compute each Fixed  Conversion  Rate in accordance with Section 14(a) or (b) and
prepare and transmit to the  Transfer  Agent an  Officer's  Certificate  setting
forth  each  Fixed  Conversion  Rate,  the  method  of  calculation  thereof  in
reasonable  detail,  and the facts requiring such adjustment and upon which such
adjustment is based; (ii) as soon as practicable  following the occurrence of an
event that  requires an  adjustment  to each Fixed  Conversion  Rate pursuant to
Section  14(a)  or (b)  hereof  (or if the  Corporation  is not  aware  of  such
occurrence,  as soon as practicable after becoming so aware),  provide, or cause
to be provided,  a written  notice to the Holders of the  Convertible  Preferred
Stock  of the  occurrence  of such  event;  and  (iii)  as  soon as  practicable
following the  determination of each revised Fixed Conversion Rate in accordance
with Section 14(a) or (b) hereof, a statement setting forth in reasonable detail
the method by which the adjustment to each Fixed  Conversion Rate was determined
and setting forth each revised Fixed Conversion Rate.

     (e) Reorganization Events. In the event of:

          (i)  any  consolidation  or  merger  of the  Corporation  with or into
     another  Person  (other  than  a  merger  or  consolidation  in  which  the
     Corporation  is the  continuing  corporation  and in which the Common Stock
     outstanding  immediately  prior  to  the  merger  or  consolidation  is not
     exchanged for cash,  securities  or other  property of the  Corporation  or
     another Person);

          (ii) any sale, transfer,  lease or conveyance to another Person of all
     or substantially all of the property and assets of the Corporation;

          (iii) any  reclassification of Common Stock into securities  including
     securities other than Common Stock; or

          (iv) any  statutory  exchange of securities  of the  Corporation  with
     another Person (other than in connection with a merger or acquisition) (any
     such event specified in this Section 14(e), a "REORGANIZATION EVENT");

each share of Convertible Preferred Stock outstanding  immediately prior to such
Reorganization Event shall, after such Reorganization Event, be convertible into
the  kind  of   securities,   cash  and  other   property   receivable  in  such
Reorganization  Event  (without  any  interest  thereon and without any right to
dividends or distribution  thereon which have a record date that is prior to the
Conversion Date) per share of Common Stock (the "EXCHANGE PROPERTY") by a holder
of Common Stock that (1) is not a person with which the Corporation consolidated
or into which the Corporation  merged or which merged into the Corporation or to
which such sale or transfer  was made,  as the case may be (any such  person,  a
"CONSTITUENT  PERSON"),  or an Affiliate of a  Constituent  Person to the extent
such Reorganization  Event provides for different treatment of Common Stock held
by Affiliates of the Corporation and non-Affiliates,  and (2) failed to exercise
his rights of election, if any, as to the kind or amount of securities, cash and
other

                                       20


property receivable upon such Reorganization Event (PROVIDED that if the kind or
amount  of   securities,   cash  and  other   property   receivable   upon  such
Reorganization  Event  is not the  same for each  share  of  Common  Stock  held
immediately  prior to such  Reorganization  Event by  other  than a  Constituent
Person or an  Affiliate  thereof and in respect of which such rights of election
shall not have been exercised  ("NON-ELECTING  SHARE"), then, for the purpose of
this Section 14(e) the kind and amount of  securities,  cash and other  property
receivable upon such  Reorganization  Event by each Non-electing  Share shall be
deemed to be the kind and amount so  receivable  per share by a plurality of the
Non-electing Shares). The amount of Exchange Property receivable upon conversion
of any  Convertible  Preferred Stock in accordance with Section 7, 8 or 9 hereof
shall be determined  based upon the Conversion Rate in effect on such Conversion
Date. The applicable  Conversion Rate shall be (x) the Minimum  Conversion Rate,
in the case of an Early  Conversion Date or a Provisional  Conversion  Date, and
(y) determined based upon the definition of Conversion Rate set forth in Section
7, in the case of the Mandatory Conversion Date.

     For  purposes of this Section  14(e),  "APPLICABLE  MARKET  VALUE" shall be
deemed to refer to the Applicable Market Value of the Exchange Property and such
value shall be  determined  (A) with respect to any publicly  traded  securities
that compose all or part of the Exchange Property, based on the Closing Price of
such  securities,  (B) in the case of any cash that  composes all or part of the
Exchange  Property,  based on the amount of such cash and (C) in the case of any
other property that composes all or part of the Exchange Property,  based on the
value of such  property,  as determined by a nationally  recognized  independent
investment  banking  firm  retained by the  Corporation  for this  purpose.  For
purposes of this  Section  14(e),  the term  "CLOSING  PRICE" shall be deemed to
refer to the closing sale price,  last quoted bid price or mid-point of the last
bid and ask prices,  as the case may be, of any publicly traded  securities that
comprise  all or part of the  Exchange  Property.  For  purposes of this Section
14(e),  references  to Common Stock in the  definition of "TRADING DAY" shall be
replaced by references to any publicly  traded  securities  that comprise all or
part of the Exchange Property.

     The  above  provisions  of this  Section  14(e)  shall  similarly  apply to
successive Reorganization Events and the provisions of Section 14 shall apply to
any shares of capital stock of the  Corporation  (or any successor)  received by
the holders of Common Stock in any such Reorganization Event.

     The Corporation (or any successor) shall,  within 20 days of the occurrence
of any  Reorganization  Event,  provide  written  notice to the  Holders of such
occurrence  of such event and of the kind and amount of the cash,  securities or
other property that constitutes the Exchange  Property.  Failure to deliver such
notice shall not affect the operation of this Section 14(e).

     (15)  Replacement  Stock  Certificates.  (a) If physical  certificates  are
issued,  and  any of the  Convertible  Preferred  Stock  certificates  shall  be
mutilated,  lost, stolen or destroyed,  the Corporation shall, at the expense of
the Holder,  issue, in exchange and in substitution for and upon cancellation of
the  mutilated  Convertible  Preferred  Stock  certificate,  or in  lieu  of and
substitution for the Convertible  Preferred Stock  certificate  lost,  stolen or
destroyed,  a new  Convertible  Preferred  Stock  certificate  of like tenor and
representing an equivalent amount of shares of Convertible  Preferred Stock, but
only upon  receipt  of  evidence  of such  loss,  theft or  destruction  of such
Convertible   Preferred   Stock   certificate   and  indemnity,   if  requested,
satisfactory to the Corporation and the Transfer Agent.

                                       21


     (b) The Corporation is not required to issue any certificates  representing
the Convertible Preferred Stock on or after the Mandatory Conversion Date or any
Provisional   Conversion  Date.  In  lieu  of  the  delivery  of  a  replacement
certificate   following  the  Mandatory   Conversion  Date  or  any  Provisional
Conversion Date, the Transfer Agent, upon delivery of the evidence and indemnity
described  above,  will deliver the shares of Common Stock issuable  pursuant to
the  terms  of  the  Convertible  Preferred  Stock  formerly  evidenced  by  the
certificate.

     (16)  Transfer  Agent,  Registrar  and  Paying  Agent.  The duly  appointed
Transfer Agent,  Registrar and Paying Agent for the Convertible  Preferred Stock
shall be The Bank of New York.  The  Corporation  may,  in its sole  discretion,
remove  the  Transfer  Agent  in  accordance  with  the  agreement  between  the
Corporation and the Transfer Agent;  PROVIDED that the Corporation shall appoint
a  successor  transfer  agent who shall  accept  such  appointment  prior to the
effectiveness  of such  removal.  Upon  any such  removal  or  appointment,  the
Corporation shall send notice thereof by first-class mail,  postage prepaid,  to
the Holders of the Convertible Preferred Stock.

     (17) Form. (a)  Convertible  Preferred Stock shall be issued in the form of
one  or  more  permanent  global  shares  of  Convertible   Preferred  Stock  in
definitive,  fully  registered  form with the global legend (the "GLOBAL  SHARES
LEGEND"),  as set forth on the form of Convertible  Preferred Stock  certificate
attached hereto as Exhibit A (each, a "GLOBAL PREFERRED SHARE"), which is hereby
incorporated in and expressly made a part of this Certificate of Amendment.  The
Global Preferred Share may have notations,  legends or endorsements  required by
law, stock exchange rules,  agreements to which the  Corporation is subject,  if
any, or usage  (PROVIDED that any such  notation,  legend or endorsement is in a
form  acceptable  to the  Corporation).  The  Global  Preferred  Share  shall be
deposited  on  behalf  of  the  holders  of  the  Convertible   Preferred  Stock
represented thereby with the Registrar, at its New York office, as custodian for
DTC or a Depositary,  and  registered in the name of the Depositary or a nominee
of the  Depositary,  duly  executed by the  Corporation  and  countersigned  and
registered by the Registrar as  hereinafter  provided.  The aggregate  number of
shares  represented  by each  Global  Preferred  Share  may from time to time be
increased or decreased by  adjustments  made on the records of the Registrar and
the Depositary or its nominee as hereinafter provided.  This Section 17(a) shall
apply  only to a Global  Preferred  Share  deposited  with or on  behalf  of the
Depositary. The Corporation shall execute and the Registrar shall, in accordance
with  this  Section,  countersign  and  deliver  initially  one or  more  Global
Preferred Shares that (i) shall be registered in the name of Cede & Co. or other
nominee of the Depositary and (ii) shall be delivered by the Registrar to Cede &
Co.  or  pursuant  to  instructions  received  from  Cede & Co.  or  held by the
Registrar as custodian for the Depositary  pursuant to an agreement  between the
Depositary and the  Registrar.  Members of, or  participants  in, the Depositary
("AGENT  MEMBERS") shall have no rights under this  Certificate  with respect to
any Global  Preferred  Share held on their  behalf by the  Depositary  or by the
Registrar as the  custodian  of the  Depositary  or under such Global  Preferred
Share, and the Depositary may be treated by the  Corporation,  the Registrar and
any agent of the  Corporation  or the  Registrar as the  absolute  owner of such
Global  Preferred  Share  for  all  purposes  whatsoever.   Notwithstanding  the
foregoing,  nothing herein shall prevent the  Corporation,  the Registrar or any
agent of the  Corporation  or the  Registrar  from giving  effect to any written
certification,  proxy or other  authorization  furnished  by the  Depositary  or
impair,  as between the  Depositary  and its Agent  Members,  the  operation  of
customary practices of the Depositary  governing the exercise of the rights of a
holder of a beneficial interest in any Global


                                       22


Preferred  Share.  The  Holder of the  Convertible  Preferred  Shares  may grant
proxies or  otherwise  authorize  any Person to take any action that a Holder is
entitled to take pursuant to the Convertible  Preferred Shares, this Certificate
of Amendment or the Certificate of Incorporation. Owners of beneficial interests
in Global Preferred Shares shall not be entitled to receive physical delivery of
certificated shares of Convertible Preferred Stock, unless (x) the Depositary is
unwilling or unable to continue as Depositary for the Global Preferred Share and
the  Corporation  does not appoint a qualified  replacement  for the  Depositary
within 90 days, (y) the Depositary ceases to be a "clearing  agency"  registered
under  the  Exchange  Act and the  Corporation  does  not  appoint  a  qualified
replacement for the Depositary within 90 days or (z) the Corporation  decides to
discontinue the use of book-entry  transfer through the Depositary.  In any such
case,  the Global  Preferred  Share shall be exchanged  in whole for  definitive
shares of Convertible  Preferred  Stock in registered  form, with the same terms
and  of  an  equal  aggregate  Liquidation  Preference.   Definitive  shares  of
Convertible  Preferred  Stock  shall be  registered  in the name or names of the
Person or Person  specified by the  Depositary  in a written  instrument  to the
Registrar.

     (b)  (i)  An  Officer  shall  sign  the  Global  Preferred  Share  for  the
Corporation,  in accordance with the Corporation's bylaws and applicable law, by
manual or facsimile signature.

     (ii) If an Officer whose signature is on a Global Preferred Share no longer
holds  that  office at the time the  Transfer  Agent  countersigned  the  Global
Preferred Share, the Global Preferred Share shall be valid nevertheless.

     (iii) A Global  Preferred  Share  shall  not be valid  until an  authorized
signatory of the Transfer Agent manually  countersigns  Global  Preferred Share.
Each Global Preferred Share shall be dated the date of its countersignature.

     (18) Miscellaneous. (a) All notices referred to herein shall be in writing,
and, unless otherwise specified herein, all notices hereunder shall be deemed to
have been given upon the earlier of receipt thereof or three Business Days after
the mailing thereof if sent by registered or certified mail (unless  first-class
mail shall be  specifically  permitted  for such notice  under the terms of this
Certificate  of  Amendment)  with  postage  prepaid,  addressed:  (i)  if to the
Corporation,  to its office at 2000  Galloping Hill Road,  Kenilworth,  NJ 07033
(Attention:  the  Secretary)  or to the Transfer  Agent at its  Corporate  Trust
Office,  or other  agent of the  Corporation  designated  as  permitted  by this
Certificate of Amendment,  or (ii) if to any Holder of the Convertible Preferred
Stock or holder of shares of Common Stock, as the case may be, to such Holder at
the  address  of  such  Holder  as  listed  in the  stock  record  books  of the
Corporation  (which  may  include  the  records  of any  transfer  agent for the
Convertible  Preferred  Stock or Common Stock,  as the case may be), or (iii) to
such other address as the  Corporation  or any such Holder,  as the case may be,
shall have designated by notice similarly given.

     (b) The  Corporation  shall pay any and all stock transfer and  documentary
stamp taxes that may be payable in respect of any issuance or delivery of shares
of  Convertible  Preferred  Stock or shares of Common Stock or other  securities
issued on account of Convertible Preferred Stock pursuant hereto or certificates
representing such shares or securities.  The Corporation shall not, however,  be
required  to pay any such tax that may be payable  in  respect  of


                                       23



any  transfer  involved in the  issuance  or  delivery of shares of  Convertible
