                                  ARTICLE 6
                            Certificates of Stock

               Section 6.1.  Issuance.  The stock of the Corporation shall be
represented by certificates, provided that the Board of Directors may provide
by resolution for any or all of the stock to be uncertificated shares.
Notwithstanding any resolution by the board of directors providing for
uncertificated shares, every holder of stock in the Corporation represented by
certificates and, upon request, every holder of uncertificated shares in the
Corporation shall be entitled to have a certificate signed by, or in the name
of the Corporation by, the chairman of the board (or the vice chairman of the
board, if any), the president or a vice president and the treasurer or an
assistant treasurer or the secretary or an assistant secretary of the
Corporation, certifying the number of shares owned by such holder in the
Corporation.

               Section 6.2.  Facsimile Signatures.  If a certificate is
countersigned (a) by a transfer agent other than the Corporation or its
employee, or (b) by a registrar other than the Corporation or its employee,
the signatures of the officers of the Corporation may be facsimiles.  In case
any officer, transfer agent or registrar who has signed or whose facsimile
signature has been placed upon a certificate shall cease to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
with the same effect as if he were such officer, transfer agent or registrar
at the date of issue.  The seal of the Corporation or a facsimile thereof may,
but need not, be affixed to certificates of stock.

               Section 6.3.  Lost Certificates, Etc.  The Board of Directors
may establish procedures for the issuance of a new certificate of stock in
place of any certificate theretofore issued by the Corporation alleged to have
been lost, stolen or destroyed and may in connection therewith require, among
other things, the making of an affidavit of that fact by the person claiming
the certificate of stock to be lost, stolen or destroyed and the giving by
such person to the Corporation of a bond in such sum as may be specified
pursuant to such procedures as indemnity against any claim that may be made
against the Corporation with respect to the certificate alleged to have been
lost, stolen or destroyed.

               Section 6.4.  Transfer.  Upon surrender to the Corporation or
the transfer agent of the Corporation of a certificate for shares duly
endorsed or accompanied by proper evidence of succession, assignment or
authority to transfer, it shall be the duty of the Corporation, if it shall be
satisfied that all provisions of the certificate of incorporation, of the
by-laws and of the law regarding the transfer of shares have been duly
complied with, to issue a new certificate to the person entitled thereto,
cancel the old certificate and record the transaction upon its books.
[Transfers of uncertificated shares shall be effected and recorded in the
manner prescribed or approved by the Board of Directors or established by the
transfer agent and approved by the Board of Directors, as the case may be.]

               Section 6.5.  Registered Stockholders.  The Corporation shall
be entitled to recognize the person registered on its books as the owner of
shares to be the exclusive owner for all purposes including voting and
dividends, and the Corporation shall not be bound to recognize any equitable
or other claim to or interest in such share or shares on the part of any other
person, whether or not it shall have express or other notice thereof, except
as otherwise provided by the laws of Delaware.

               Section 6.6.  Record Date.  In order that the Corporation may
determine the stockholders entitled to notice of or to vote at any meeting of
stockholders or any adjournment thereof, or to express consent to corporate
action in writing without a meeting, or entitled to receive payment of any
dividend or other distribution or allotment of any rights, or entitled to
exercise any rights in respect of any change, conversion or exchange of stock
or for the purpose of any other lawful action, the Board of Directors may fix,
in advance, a record date, which shall not be more than sixty or less than ten
days before the date of such meeting, and not more than sixty days prior to
any other action.  A determination of stockholders of record entitled to
notice of or to vote at a meeting of stockholders shall apply to any
adjournment of the meeting; provided, however, that the Board of Directors may
fix a new record date for the adjourned meeting.



                                  ARTICLE 7
                                Miscellaneous

               Section 7.1.  Declaration of Dividends.  Dividends upon the
shares of the capital stock of the Corporation may be declared and paid by the
Board of Directors from the funds legally available therefor.  Dividends may
be paid in cash, in property, or in shares of the capital stock of the
corporation.

               Section 7.2.  Reserves.  The directors of the Corporation may
set apart out of any of the funds of the Corporation available for dividends a
reserve or reserves for such purposes as the directors shall think conducive
to the interest of the Corporation, and the directors may modify or abolish
any such reserve.

               Section 7.3.  Fiscal Year.  The fiscal year of the Corporation
shall be fixed by resolution of the Board of Directors.

               Section 7.4.  Corporate Seal.  The corporate seal shall have
inscribed thereon the name of the Corporation, the year of its organization
and the words "Corporate Seal, Delaware".  The seal may be used by causing it
or a facsimile thereof to be impressed or affixed or in any other manner
reproduced.



                                  ARTICLE 8
                               Indemnification

               Section 8.1.  In General.  Any person who was or is a party or
is threatened to be made a party to or is involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that he or a person of whom is the legal representative, is
or was a director, officer, employee or agent of the Corporation, or is or was
serving at the request of the Corporation or for its benefit as a director,
officer, employee or agent of another corporation, or as its representative in
a partnership, joint venture, trust or other enterprise, shall be indemnified
and held harmless to the fullest extent legally permissible under and pursuant
to any procedure specified in or pursuant to the General Corporation Law of
the State of Delaware, as amended from time to time, from and against any and
all expenses, liabilities and losses (including without limitation attorney's
fees, judgments, fines and amounts paid or to be paid in settlement) actually
and reasonably incurred or suffered by such person in connection therewith.
Such right of indemnification shall be a contract right which may be enforced
in any manner desired by such person.  Such right of indemnification shall not
be exclusive of any other right which such directors, officers, employees,
agents or representatives may have or hereafter acquire and, without limiting
the generality of the foregoing, they shall be entitled to their respective
rights of indemnification under any by-law, agreement, vote of stockholders
or the Board of Directors, provision of law or otherwise, as well as their
rights under this Article.

               Section 8.2.  Insurance.  The Board of Directors may cause the
Corporation to purchase and maintain insurance on behalf of any person who is
or was a director, officer, employee or agent of the Corporation, or is or was
serving at the request of the Corporation as a director, officer, employee or
agent of another corporation or as its representative in a partnership, joint
venture, trust or other enterprise against any liability asserted against such
person and incurred in any such capacity, or arising out of such status,
whether or not the Corporation would have the power to indemnify such person
against such liability.

               Section 8.3.  Additional Indemnification.  The Board of
Directors may from time to time adopt further by-laws with respect to
indemnification and may amend these by-laws and such by-laws to provide at all
times the fullest indemnification permitted by the General Corporation Law of
the State of Delaware, as amended from time to time.



                                  ARTICLE 9
                                 Amendments

               Section 9.1.  By the Stockholders.  The by-laws may be amended
by a majority vote of all the stock issued and outstanding and entitled to
vote at any annual or special meeting of the stockholders, provided that
notice of intention to amend shall have been contained in the notice of the
meeting.

               Section 9.2.  By the Board of Directors.  The Board of
Directors by a majority vote of the whole Board of Directors at any meeting
may amend these by-laws, including by-laws adopted by the stockholders, but
the stockholders may from time to time specify particular provisions of the
by-laws which shall not be amended by the Board of Directors.
                                                                    EXHIBIT 3

                      Pursuant to Section 151 of the
             General Corporation Law of the State of Delaware


               The undersigned, pursuant to the provisions of Sections 103 and
151 of the General Corporation Law of the State of Delaware, do hereby certify
that, pursuant to the authority expressly vested in the Board of Directors of
W. R. Grace & Co., a Delaware corporation (the "Corporation"), by the
Corporation's Certificate of Incorporation, the Board of Directors has duly
adopted the following resolutions:

               RESOLVED that pursuant to the authority expressly granted to
and vested in the Board of Directors of the Corporation by the Corporation's
Certificate of Incorporation, the Board of Directors hereby provides for the
issuance of and creates a series of Preferred Stock of the Corporation, par
value $0.10 per share (the "Preferred Stock"), and hereby fixes the
designation and amount and the voting powers, designations, preferences and
relative, participating, optional and other special rights, and the
qualifications, limitations and restrictions, of a series of Preferred Stock.

               RESOLVED that each share of such series of Preferred Stock
shall rank equally in all respects and shall be subject to the following
provisions:

               1.  Number of Shares and Designation. 36,000,000 shares of
Preferred Stock of the Corporation shall constitute a series of Preferred
Stock designated as Series A Convertible Preferred Stock (the "Series A
Preferred Stock").  The number of shares of Series A Preferred Stock may be
increased (to the extent of the Corporation's authorized and unissued
Preferred Stock) or decreased (but not below the number of shares of Series
A Preferred Stock then outstanding) by further resolution duly adopted by
the Board of Directors and the filing of a certificate of increase or
decrease, as the case may be, with the Secretary of State of Delaware.

               2.  Rank.  The Series A Preferred Stock shall, with respect
to payment of dividends, redemption payments and rights upon liquidation,
dissolution or winding up of the affairs of the Corporation, (i) rank
senior and prior to the Common Stock of the Corporation, par value $0.10
per share (the "Common Stock"), and each other class or series of equity
securities of the Corporation, whether currently issued or issued in the
future, that by its terms ranks junior to the Series A Preferred Stock
(whether with respect to payment of dividends, redemption payments or
rights upon liquidation, dissolution or winding up of the affairs of the
Corporation)  (all of such equity securities, including the Common Stock,
are collectively referred to herein as the "Junior Securities"), (ii) rank
on a parity with each other class or series of equity securities of the
Corporation (other than the Common Stock), whether currently issued or
issued in the future, that does not by its terms expressly provide that it
ranks senior to or junior to the Series A Preferred Stock (whether with
respect to payment of dividends, redemption payments or rights upon
liquidation, dissolution or winding up of the affairs of the Corporation)
(all of such equity securities are collectively referred to herein as the
"Parity Securities"), and (iii) rank junior to each other class or series
of equity securities of the Corporation, whether currently issued or issued
in the future, that by its terms ranks senior to the Series A Preferred
Stock (whether with respect to payment of dividends, redemption payments or
rights upon liquidation, dissolution or winding up of the affairs of the
Corporation)  (all of such equity securities are collectively referred to
herein as the "Senior Securities").  The respective definitions of Junior
Securities, Parity Securities and Senior Securities shall also include any
rights or options exercisable or exchangeable for or convertible into any
of the Junior Securities, Parity Securities or Senior Securities, as the
case may be.

               3.  Dividends.

               (a)  The holders of shares of Series A Preferred Stock shall be
entitled to receive, when, as and if declared by the Board of Directors, out
of funds legally available for the payment of dividends, cash dividends at the
annual rate of $2.00 per share.  Such dividends shall be payable quarterly in
arrears, in equal amounts, on ________, ________, ________ and ________ of
each year (unless such day is not a Business Day (as defined below), in which
event such dividends shall be payable  on the next succeeding Business Day),
commencing _____________ ___, 1998 (each such payment date being a "Dividend
Payment Date" and from the date of issuance until the first Dividend Payment
Date and each quarterly period thereafter being a "Dividend Period").
Dividends on shares of Series A Preferred Stock shall be cumulative from the
date of issue, whether or not in any Dividend Period there shall be funds of
the Corporation legally available for the payment of dividends.  The amount of
dividends payable for each full Dividend Period shall be computed by dividing
the annual dividend rate by four.  The amount of dividends payable on the
Series A Preferred Stock for the initial Dividend Period, or for any other
period shorter or longer than a full Dividend Period, shall be computed on the
basis of a 360-day year of  twelve 30-day months.  As used herein, the term
"Business Day" means any day except a Saturday, Sunday or day on which banking
institutions are legally authorized to close in the City of New York.

               (b) Each dividend shall be payable to the holders of record of
shares of Series A Preferred Stock as they appear on the stock records of the
Corporation at the close of business on such record dates (each, a "Dividend
Payment Record Date"), which shall be not more than 60 days nor less than 10
days preceding the Dividend Payment Date thereof, as shall be fixed by the
Board of Directors.  Accrued and unpaid dividends for any past Dividend
Periods may be declared and paid at any time, without reference to any
Dividend Payment Date, to holders of record on such date, not more than 60
days nor less than 10 days preceding the payment date thereof, as may be fixed
by the Board of Directors.  No interest, or sum of money in lieu of interest,
shall be payable in respect of any dividend payment or payments on the Series
A Preferred Stock that may be in arrears.

               (c) Except as described in the next succeeding sentence, so
long as any shares of Series A Preferred Stock are outstanding, (i) no
dividends shall be declared or paid or  set apart for payment, or other
distribution declared or made, on any Parity Securities for any period unless
the Corporation has paid or contemporaneously pays or declares and sets apart
for payment on the Series A Preferred Stock all accrued and unpaid dividends
for all Dividend Periods terminating on or prior to the date of payment of
such dividends, and (ii) no dividends shall be declared or paid or set apart
for payment, or other distribution declared or made, on the Series A Preferred
Stock for any Dividend Period unless the Corporation has paid or
contemporaneously pays or declares and sets apart for payment on any Parity
Securities all accrued and unpaid dividends for all dividend payment periods
terminating on or prior to the Dividend Payment Date for such dividends.
Unless and until dividends accrued but unpaid in respect of all past Dividend
Periods with respect to the Series A Preferred Stock and all past dividend
periods with respect to any Parity Securities at the time outstanding shall
have been paid in full or a sum sufficient for such payment is set apart, all
dividends declared by the Corporation upon shares of Series A Preferred Stock
and upon all Parity Securities shall be declared ratably in proportion to the
respective amounts of dividends accrued and unpaid on the Series A Preferred
Stock and Parity Securities.

               (d) So long as any shares of Series A Preferred Stock are
outstanding, no dividends shall be declared or paid or set apart for payment,
or other distribution declared or made, upon any Junior Securities (other than
dividends or distributions paid in shares of, or options, warrants or rights
to subscribe for or purchase shares of Junior Securities), nor shall any
Junior Securities be redeemed, purchased or otherwise acquired (other than a
redemption, purchase or other acquisition of shares of Common Stock made for
purposes of any employee or director incentive or benefit plans or
arrangements of the Corporation or any subsidiary of the Corporation) for any
consideration (nor shall any moneys be paid to or made available for a sinking
fund for the redemption of any shares of any such Junior Securities) by the
Corporation, directly or indirectly (except by conversion into or exchange for
Junior Securities), unless in each case (i) the full cumulative dividends on
all outstanding shares of Series A Preferred Stock and any other Parity
Securities shall have been paid or set apart for payment for all past Dividend
Periods with respect to the Series A Preferred Stock and all past dividend
periods with respect to such Parity Securities and (ii) sufficient funds shall
have been paid or set apart for the payment of the dividend for the current
Dividend Period with respect to the Series A Preferred Stock and for the
current dividend period with respect to such Parity Securities.

               (e) The Corporation shall not, directly or indirectly, make any
payment on account of any purchase, redemption, retirement or other
acquisition of any Parity Securities (other than for consideration payable
solely in Junior Securities) unless all accrued and unpaid dividends on the
Series A Preferred Stock for all Dividend Payment Periods ending on or before
such payment for such Parity Securities shall have been paid or declared and
set apart for payment.

               (f) If at any time the Corporation issues any Senior Securities
and the Corporation shall have failed to declare and pay or set apart for
payment accrued and unpaid dividends on such Senior Securities, in whole or in
part, then (except to the extent allowed by the terms of the Senior
Securities) no dividends shall be declared or paid or set apart for payment on
the Series A Preferred Stock unless and until all accrued and unpaid dividends
with respect to the Senior Securities, including the full dividends for the
then-current dividend period, shall have been declared and paid or set apart
for payment.

               4. Liquidation Preference.

               (a) The liquidation preference for the shares of Series A
Preferred Stock shall be $50.00 per share, plus an amount equal to the
dividends accrued and unpaid thereon, whether or not declared, to the payment
date (the "Liquidation Value").

               (b) In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of shares of Series
A Preferred Stock (i) shall not be entitled to receive the Liquidation Value
of such shares until payment in full or provision has been made for the
payment in full of all claims of creditors of the Corporation and the
liquidation preferences for all Senior Securities, and (ii) shall be entitled
to receive the Liquidation Value of such shares before any payment or
distribution of any assets of the Corporation shall be made or set apart for
holders of any Junior Securities.  Subject to clause (i) above, if the assets
of the Corporation are not sufficient to pay in full the Liquidation Value
payable to the holders of shares of Series A Preferred Stock and the
liquidation preference payable to the holders of any Parity Securities, then
such assets, or the proceeds thereof, shall be distributed among the holders
of shares of Series A Preferred Stock and any such other Parity Securities
ratably in accordance with the Liquidation Value for the Series A Preferred
Stock and the liquidation preference for the Parity Securities, respectively.
Upon payment in full of the Liquidation Value to which the holders of shares
of Series A Preferred Stock are entitled, the holders of shares of Series A
Preferred Stock will not be entitled to any further participation in any
distribution of assets of the Corporation.

               (c) Neither a consolidation or merger of the Corporation with
or into any other entity, nor a merger of any other entity with or into the
Corporation, nor a sale or transfer of all or any part of the Corporation's
assets for cash, securities or other property shall be considered a
liquidation, dissolution or winding up of the Corporation within the meaning
of this Section 4.

               5.  Redemption.

               (a) Optional Redemption.  The Series A Preferred Stock shall
not be redeemable prior to __________ __, 2001.  During the period from
__________ __, 2001 until __________ __, 2003, the Corporation may redeem at
its option shares of Series A Preferred Stock in accordance with this Section
5 only if the last reported sales price of a share of Common Stock in its
principal trading market for any 20 trading days within a period of 30
consecutive trading days ending on the trading day prior to the date of
mailing the notice of redemption is at least $70.6563.  At any time on or
after __________ __, 2001, to the extent the Corporation shall have funds
legally available to redeem shares of Series A Preferred Stock and if
permitted by the immediately preceding sentence, the Corporation may redeem
shares of Series A Preferred Stock, in whole or in part, at the option of the
Corporation, at the applicable cash redemption price per share set forth below
for any redemption during the 12-month period beginning on _______ ____ of the
year indicated:

                Year             Redemption Price Per Share
               ------           ----------------------------
                2001                       $51.40
                2002                       $51.20
                2003                       $51.00
                2004                       $50.80
                2005                       $50.60
                2006                       $50.40
                2007                       $50.20
                Thereafter                 $50.00

plus, in each case, an amount equal to the dividends accrued and unpaid
thereon, whether or not declared, up to but not including the redemption date.
From and after __________ __, 2008, the Corporation may redeem shares of
Series A Preferred Stock, at any time in whole or in part, at the option of
the Corporation, at a cash redemption price per share of $50.00 plus an amount
equal to the dividends accrued and unpaid thereon, whether or not declared, up
to but not including the redemption date.

               (b)  Mandatory Redemption.  To the extent the Corporation shall
have funds legally available for such payment, on __________ __, 2018 (the
"Mandatory Redemption Date), the Corporation shall redeem all outstanding
shares of Series A Preferred Stock at a redemption price of $50.00 per share
in cash, together with accrued and unpaid dividends thereon, whether or not
declared, up to but not including such redemption date, without interest.  If
the Corporation is unable or shall fail to discharge its obligation to redeem
all outstanding shares of Series A Preferred Stock on the Mandatory Redemption
Date (the "Mandatory Redemption Obligation"):  (i) dividends on the Series A
Preferred Stock shall continue to accrue, without interest, in accordance with
Section 3, and (ii) the Mandatory Redemption Obligation shall be discharged as
soon thereafter as the Corporation is able to discharge such Mandatory
Redemption Obligation.  If and for so long as any Mandatory Redemption
Obligation with respect to the Series A Preferred Stock shall not be fully
discharged on the Mandatory Redemption Date, the Corporation shall not (x)
directly or indirectly, redeem, purchase, or otherwise acquire any Parity
Securities or discharge any mandatory or optional redemption, sinking fund or
other similar obligation in respect of any Parity Securities (except in
connection with a redemption, sinking fund or other similar obligation to be
satisfied pro rata with the Series A Preferred Stock) or (y) declare or pay or
set apart for payment any dividends or other distributions upon any Junior
Securities, or, directly or indirectly, discharge any mandatory or optional
redemption, sinking fund or other similar obligation in respect of any Junior
Securities.

               6.  Procedures for Redemption.

               (a) If fewer than all of the outstanding shares of Series A
Preferred Stock are to be redeemed pursuant to Section 5, the shares shall be
redeemed on a pro rata basis (according to the number of shares of Series A
Preferred Stock held by each holder, with any fractional shares rounded to the
nearest whole share) or in such other manner as the Board of Directors may
determine, as may be prescribed by resolution of the Board of Directors.
Notwithstanding the provisions of Section 5 and this Section 6, unless full
cumulative cash dividends (whether or not declared) on all outstanding shares
of Series A Preferred Stock shall have been paid or contemporaneously are
declared and paid or set apart for payment for all Dividend Periods
terminating on or prior to the applicable redemption date, none of the shares
of Series A Preferred Stock shall be redeemed, and no sum shall be set aside
for such redemption, unless shares of Series A Preferred Stock are redeemed
pro rata.

               (b) In the event of a redemption of shares of Series A
Preferred Stock pursuant to Section 5, notice of such redemption shall be
given by first class mail, postage prepaid, mailed not less than 15 days nor
more than 60 days prior to the redemption date, to each holder of record of
the shares to be redeemed at such holder's address as the same appears on the
stock register of the Corporation; provided that neither the failure to give
such notice nor any defect therein shall affect the validity of the giving of
notice for the redemption of any share of Series A Preferred Stock to be
redeemed, except as to the holder to whom the Corporation has failed to give
said notice or except as to the holder whose notice was defective.  Each such
notice shall state: (i) the redemption date; (ii) the number of shares of
Series A Preferred Stock to be redeemed and, if fewer than all the shares held
by such holder are to be redeemed, the number of shares to be redeemed from
such holder; (iii) the redemption price; (iv) the place or places where
certificates for such shares are to be surrendered for payment of the
redemption price; and (v) that dividends on the shares to be redeemed will
cease to accrue on such redemption date.  Any notice mailed in the manner
herein provided shall be conclusively presumed to have been duly given whether
or not the holder receives the notice.

               (c) If a notice of redemption has been given pursuant to
Section 6(b) and if, on or before the redemption date, the funds necessary for
such redemption (including all dividends on the shares of Series A Preferred
Stock to be redeemed that will accrue to but not including the redemption
date) shall have been set aside by the Corporation, separate and apart from
its other funds, in trust for the pro rata benefit of the holders of the
shares so called for redemption, then on the redemption date, notwithstanding
that any certificates for such shares have not been surrendered for
cancellation, (i) dividends shall cease to accrue on the shares of Series A
Preferred Stock to be redeemed, (ii)  the holders of such shares shall cease
to be stockholders with respect to those shares, shall have no interest in or
claims against the Corporation by virtue thereof and shall have no voting or
other rights with respect thereto, except the conversion rights provided in
Section 7 (in accordance with Section 6(e)) and the right to receive the
monies payable upon such redemption, without interest thereon, upon surrender
(and endorsement, if required by the Corporation) of their certificates, and
(iii) the shares evidenced thereby shall no longer be outstanding.  Subject to
applicable escheat laws, any monies so set aside by the Corporation and
unclaimed at the end of two years from the redemption date shall revert to the
general funds of the Corporation, after which reversion the holders of such
shares so called for redemption shall look only to the general funds of the
Corporation for the payment of the redemption price, without interest.  Any
interest accrued on funds so deposited shall belong to the Corporation and be
paid thereto from time to time.

               (d) Upon surrender in accordance with the Corporation's notice
of redemption of the certificates for any shares so redeemed (properly
endorsed or assigned for transfer, if the Board of Directors shall so require
and the notice shall so state), such shares shall be redeemed by the
Corporation at the redemption price aforesaid.  In case fewer than all the
shares represented by any such certificate are redeemed, a new certificate
shall be issued representing the unredeemed shares without cost to the holder
thereof.

               (e) If a notice of redemption has been given pursuant to
Section 6(b) and any holder of shares of Series A Preferred Stock shall, prior
to the close of business on the Business Day preceding the redemption date,
give written notice to the Corporation pursuant to Section 7 of the conversion
of any or all of the shares to be redeemed held by the holder (accompanied by
a certificate or certificates for such shares, duly endorsed or assigned to
the Corporation, and any necessary transfer tax payment, as required by
Section 7), then such redemption shall not become effective as to such shares
to be converted and such conversion shall become effective as provided in
Section 7, whereupon any funds deposited by the Corporation for the redemption
of such shares shall (subject to any right of the holder of such shares to
receive the dividend payable thereon as provided in Section 7) immediately
upon such conversion be returned to the Corporation or, if then held in trust
by the Corporation, shall automatically and without further corporate action
or notice be discharged from the trust.

               7.  Conversion.

               (a)  Right to Convert.

                    (i)  Subject to the provisions of this Section 7, each
               holder of shares of Series A Preferred Stock shall have the
               right, at any time and from time to time, at such holder's
               option, to convert any or all of such holder's shares of
               Series A Preferred Stock, in whole or in part, into fully
               paid and non-assessable shares of Common Stock at the
               conversion price of $56.525 per share of Common Stock,
               subject to adjustment as described in Section 7(c)  (as
               adjusted, the "Conversion Price").  The number of shares of
               Common Stock into which a share of the Series A Preferred
               Stock shall be convertible (calculated as to each conversion
               to the nearest 1/1,000,000th of a share) shall be determined
               by dividing $50.00 by the Conversion Price in effect at the
               time of conversion.

                   (ii)  If shares of Series A Preferred Stock are called
               for redemption in accordance with Section 5(a), the right to
               convert shares so called for redemption shall terminate at
               the close of business on the Business Day immediately
               preceding the date fixed for redemption unless the
               Corporation shall default in making payment of the amount
               payable upon such redemption, in which case the conversion
               rights for such shares shall continue.

               (b)  Mechanics of Conversion.

                     (i)  To exercise the conversion right, the holder of
               shares of Series A Preferred Stock to be converted shall
               surrender the certificate or certificates representing such
               shares at the office of the Corporation (or any transfer
               agent of the Corporation previously designated by the
               Corporation to the holders of Series A Preferred Stock for
               this purpose) with a written notice of election to convert
               completed and signed, specifying the number of shares to be
               converted.  Unless the shares issuable upon conversion are
               to be issued in the same name as the name in which such
               shares of Series A Preferred Stock are registered, each
               share surrendered for conversion shall be accompanied by
               instruments of transfer, in form satisfactory to the
               Corporation, duly executed by the holder or the holder's
               duly authorized attorney and an amount sufficient to pay any
               transfer or similar tax in accordance with Section
               7(b)(vii).  As promptly as practicable after the surrender
               by the holder of the certificates for shares of Series A
               Preferred Stock as aforesaid, the Corporation shall issue
               and shall deliver to such holder, or on the holder's written
               order to the holder's transferee, a certificate or
               certificates for the whole number of shares of Common Stock
               issuable upon the conversion of such shares and a check
               payable in an amount corresponding to any fractional
               interest in a share of Common Stock as provided in Section
               7(b)(viii).

                   (ii)  Each conversion shall be deemed to have been
               effected immediately prior to the close of business on the
               first Business Day (the "Conversion Date") on which the
               certificates for shares of Series A Preferred Stock shall
               have been surrendered and such notice received by the
               Corporation as aforesaid.  At such time on the Conversion
               Date:

                          (w) the person in whose name or names any
                    certificate or certificates for shares of Common Stock
                    shall be issuable upon such conversion shall be deemed
                    to have become the holder of record of the shares of
                    Common Stock represented thereby at such time;

                          (x) such shares of Series A Preferred Stock shall
                    no longer be deemed to be outstanding and all rights of
                    a holder with respect to such shares surrendered for
                    conversion shall immediately terminate except the right
                    to receive the Common Stock and other amounts payable
                    pursuant to this Section 7;

                          (y) in lieu of dividends on such Series A
                    Preferred Stock pursuant to Section 3, such shares of
                    Series A Preferred Stock shall participate equally and
                    ratably with the holders of shares of Common Stock in
                    all dividends paid on the Common Stock; and

                          (z) the right of the Corporation to redeem such
                    shares of Series A Preferred Stock shall terminate,
                    regardless of whether a notice of redemption has been
                    mailed as aforesaid.

               All shares of Common Stock delivered upon conversion of the
               Series A Preferred Stock will, upon delivery, be duly and
               validly issued and fully paid and non-assessable, free of
               all liens and charges and not subject to any preemptive
               rights.

                   (iii)  Holders of shares of Series A Preferred Stock at the
               close of business on a Dividend Payment Record Date shall be
               entitled to receive the dividend payable on such shares on
               the corresponding Dividend Payment Date notwithstanding the
               conversion thereof following such Dividend Payment Record
               Date and prior to such Dividend Payment Date.  However,
               shares of Series A Preferred Stock surrendered for
               conversion during the period between the close of business
               on any Dividend Payment Record Date and the opening of
               business on the corresponding Dividend Payment Date (except
               shares converted after the issuance of a notice of
               redemption during such period, which shall be entitled to
               such dividend on the Dividend Payment Date) must be
               accompanied by payment of an amount equal to the dividend
               payable on such shares on such Dividend Payment Date;
               provided that notwithstanding such surrender of shares for
               conversion after such Dividend Payment Record Date, the
               holders thereof at the close of business on such Dividend
               Payment Record Date shall be entitled to receive the
               dividend payable on such shares on the corresponding
               Dividend Payment Date.  A holder of shares of Series A
               Preferred Stock on a Dividend Payment Record Date who (or
               whose transferee) tenders any such shares for conversion
               into shares of Common Stock on such Dividend Payment Date
               will receive the dividend payable by the Corporation on such
               shares of Series A Preferred Stock on such date, and the
               converting holder need not include payment of the amount of
               such dividend upon surrender of shares of Series A Preferred
               Stock for conversion.

                   (iv)  Except as provided in clause (iii) above and in
               Section 7(c), the Corporation shall make no payment or
               adjustment for accrued and unpaid dividends on shares of
               Series A Preferred Stock, whether or not in arrears, on
               conversion of such shares or for dividends in cash on the
               shares of Common Stock issued upon such conversion.

                   (v)  The Corporation covenants that it will at all times
               reserve and keep available, free from preemptive rights,
               such number of its authorized but unissued shares of Common
               Stock as shall be required for the purpose of effecting
               conversions of the Series A Preferred Stock.  Prior to the
               delivery of any securities which the Corporation shall be
               obligated to deliver upon conversion of the Series A
               Preferred Stock, the Corporation shall comply with all
               applicable federal and state laws and regulations which
               require action to be taken by the Corporation.

                   (vi)  The Corporation will pay any and all documentary
               stamp or similar issue or transfer taxes payable in respect
               of the issuance or delivery of shares of Common Stock on
               conversion of the Series A Preferred Stock pursuant hereto;
               provided that the Corporation shall not be required to pay
               any tax which may be payable in respect of any transfer
               involved in the issuance or delivery of shares of Common
               Stock in a name other than that of the holder of the Series
               A Preferred Stock to be converted, and no such issuance or
               delivery shall be made unless and until the person
               requesting such issuance or delivery 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.

                   (vii)  In connection with the conversion of any shares of
               Series A Preferred Stock, no fractions of shares of Common
               Stock shall be issued, but in lieu thereof the Corporation
               shall pay a cash adjustment in respect of such fractional
               interest in an amount equal to such fractional interest
               multiplied by the Daily Price (as defined below) per share
               of Common Stock on the Conversion Date.  In the absence of a
               Daily Price, the Board of Directors shall in good faith
               determine the current market price on such basis as it
               considers appropriate, and such current market price shall
               be used to calculate the cash adjustment.  As used herein,
               "Daily Price" means (w) if the shares of such class of
               Common Stock are then listed and traded on the New York
               Stock Exchange, Inc.  ("NYSE"), the closing price on such
               day as reported on the NYSE Composite Transactions Tape;
               (x) if the shares of such class of Common Stock are not then
               listed and traded on the NYSE, the closing price on such day
               as reported by the principal national securities exchange on
               which the shares are listed and traded;  (y) if the shares
               of such class of Common Stock are not then listed and traded
               on any such securities exchange, the last reported sale
               price on such day on the National Market of the National
               Association of Securities Dealers, Inc.  Automated Quotation
               System ("NASDAQ"); or (z) if the shares of such class of
               Common Stock are not then traded on the NASDAQ National
               Market, the average of the highest reported bid and lowest
               reported asked price on such day, as reported by NASDAQ.

               (c)  Adjustments to Conversion Price.  The Conversion Price
shall be adjusted from time to time as follows:

                   (i)  If, at any time after the date of issuance of the
               Series A Preferred Stock, the Corporation shall (A) pay a
               dividend or make a distribution on any class of its capital
               stock in shares of its Common Stock, (B) subdivide its
               outstanding shares of Common Stock into a greater number of
               shares or (C) combine its outstanding shares of Common Stock
               into a smaller number of shares, the Conversion Price in
               effect immediately prior thereto shall be adjusted as
               provided below so that the Conversion Price thereafter shall
               be determined by multiplying the Conversion Price at which
               the shares of Series A Preferred Stock were theretofore
               convertible by a fraction, the numerator of which shall be
               the number of shares of Common Stock outstanding immediately
               prior to such action, and the denominator of which shall be
               the number of shares of Common Stock outstanding immediately
               following such action.  Such adjustment shall be made
               whenever any event listed above shall occur and shall become
               effective retroactively immediately after the record date in
               the case of a dividend and immediately after the effective
               date in the case of a subdivision or combination.

                   (ii)  If, at any time after the date of issuance of the
               Series A Preferred Stock, the Corporation shall issue rights
               or warrants to all holders of its Common Stock entitling
               them (for a period expiring within 45 days after the record
               date for determining stockholders entitled to receive such
               rights or warrants) to subscribe for or purchase shares of
               Common Stock at a price per share less than the current
               market price per share of Common Stock at the record date
               therefor (as determined in accordance with the provisions of
               Section 7(c)(iv)), the "Current Market Price"), or in case
               the Corporation shall issue to all holders of its Common
               Stock other securities convertible into or exchangeable for
               Common Stock for a consideration per share of Common Stock
               deliverable upon conversion or exchange thereof less than
               the Current Market Price, then the Conversion Price in
               effect immediately prior thereto shall be adjusted as
               provided below so that the Conversion Price therefor shall
               be equal to the price determined by multiplying (A) the
               Conversion Price at which shares of Series A Preferred Stock
               were theretofore convertible by (B) a fraction of which the
               numerator shall be the sum of (1) the number of shares of
               Common Stock outstanding on the date of issuance of the
               convertible or exchangeable securities, rights or warrants
               and (2) the number of additional shares of Common Stock that
               the aggregate offering price for the number of shares of
               Common Stock so offered would purchase at the Current Market
               Price per share of Common Stock, and of which the
               denominator shall be the sum of (1) the number of shares of
               Common Stock outstanding on the date of issuance of such
               convertible or exchangeable securities, rights or warrants
               and (2) the number of additional shares of Common Stock
               offered for subscription or purchase, or issuable upon such
               conversion or exchange.  Such adjustment shall be made
               whenever such convertible or exchangeable securities, rights
               or warrants are issued, and shall become effective
               immediately after the record date for the determination of
               stockholders entitled to receive such securities.  However,
               upon the expiration of any right or warrant to purchase
               Common Stock, the issuance of which resulted in an
               adjustment in the Conversion Price pursuant to this Section
               7(c)(ii), if any such right or warrant shall expire and
               shall not have been exercised, the Conversion Price shall be
               recomputed immediately upon such expiration and effective
               immediately upon such expiration shall be increased to the
               price it would have been (but reflecting any other
               adjustments to the Conversion Price made pursuant to the
               provisions of this Section 7(c) after the issuance of such
               rights or warrants) had the adjustment of the Conversion
               Price made upon the issuance of such rights or warrants been
               made on the basis of offering for subscription or purchase
               only that number of shares of Common Stock actually
               purchased upon the exercise of such rights or warrants.  No
               further adjustment shall be made upon exercise of any right,
               warrant, convertible security or exchangeable security if
               any adjustment shall have been made upon issuance of such
               security.

                   (iii)  If, at any time after the date of issuance of the
               Series A Preferred Stock, the Corporation shall distribute
               to all holders of its Common Stock (including any dividend
               paid in connection with a consolidation or merger in which
               the Corporation is the continuing corporation) any shares of
               capital stock of the Corporation or its subsidiaries (other
               than Common Stock) or evidences of its indebtedness, cash or
               other assets (excluding dividends payable solely in cash
               that may from time to time be fixed by the Board of
               Directors, or dividends or distributions in connection with
               the liquidation, dissolution or winding up of the
               Corporation) or rights or warrants to subscribe for or
               purchase any of its securities or those of its subsidiaries
               or securities convertible or exchangeable for Common Stock
               (excluding those securities referred to in Section
               7(c)(ii)), then in each such case the Conversion Price in
               effect immediately prior thereto shall be adjusted as
               provided below so that the Conversion Price thereafter shall
               be equal to the price determined by multiplying (A) the
               Conversion Price in effect on the record date mentioned
               below by (B) a fraction, the numerator of which shall be the
               Current Market Price per share of Common Stock on the record
               date mentioned below less the then fair market value (as
               determined by the Board of Directors, whose good faith
               determination shall be conclusive) as of such record date of
               the assets, evidences of indebtedness or securities so paid
               with respect to one share of Common Stock, and the
               denominator of which shall be the Current Market Price per
               share of Common Stock on such record date; provided,
               however, that in the event the then fair market value (as so
               determined) so paid with respect to one share of Common
               Stock is equal to or greater than the Current Market Price
               per share of Common Stock on the record date mentioned
               above, in lieu of the foregoing adjustment, adequate
               provision shall be made so that each holder of shares of
               Series A Preferred Stock shall have the right to receive the
               amount and kind of assets, evidences of indebtedness, or
               securities such holder would have received had such holder
               converted each such share of Series A Preferred Stock
               immediately prior to the record date for such dividend.
               Such adjustment shall be made whenever any such payment is
               made, and shall become effective retroactively immediately
               after the record date for the determination of stockholders
               entitled to receive the payment.

                   (iv)  For the purpose of any computation under Sections
               7(c)(ii) or 7(c)(iii), the Current Market Price per share of
               Common Stock at any date shall be deemed to be the average
               Daily Price for the 30 consecutive trading days commencing
               35 trading days before the day in question.

                   (v)  No adjustment in the Conversion Price shall be
               required unless the adjustment would require an increase or
               decrease of at least 1% in the Conversion Price then in
               effect; provided, however, that any adjustments that by
               reason of this Section 7(c)(v) are not required to be made
               shall be carried forward and taken into account in any
               subsequent adjustment.  All calculations under this Section
               7(c) shall be made to the nearest cent.

                   (vi)  In the event that, at any time as a result of an
               adjustment made pursuant to Section 7(c)(i) or 7(c)(iii),
               the holder of any shares of Series A Preferred Stock
               thereafter surrendered for conversion shall become entitled
               to receive any shares of the Corporation or its
               subsidiaries, other than shares of the Common Stock,
               thereafter the number of such other shares so receivable
               upon conversion of any share of Series A Preferred Stock
               shall be subject to adjustment from time to time in a manner
               and on terms as nearly equivalent as practicable to the
               provisions with respect to the Common Stock contained in
               Sections 7(c)(i) through 7(c)(v), and the other provisions
               of this Section 7 with respect to the Common Stock shall
               apply on like terms to any such other shares.

                   (vii)  Whenever the Conversion Price is adjusted, as
               herein provided, the Corporation shall promptly file with
               the transfer agent for the Series A Preferred Stock a
               certificate of an officer of the Corporation setting forth
               the Conversion Price after the adjustment and setting forth
               a brief statement of the facts requiring such adjustment and
               a computation thereof.  The certificate shall be prima facie
               evidence of the correctness of the adjustment.  The
               Corporation shall promptly cause a notice of the adjusted
               Conversion Price to be mailed to each registered holder of
               shares of Series A Preferred Stock.

                   (viii)  In case of any reclassification of the Common
               Stock, any consolidation of the Corporation with, or merger
               of the Corporation into, any other entity, any merger of
               another entity into the Corporation (other than a merger
               that does not result in any reclassification, conversion,
               exchange or cancellation of outstanding shares of Common
               Stock of the Corporation), any sale or transfer of all or
               substantially all of the assets of the Corporation or any
               compulsory share exchange pursuant to which share exchange
               the Common Stock is converted into other securities, cash or
               other property, then lawful provision shall be made as part
               of the terms of such transaction whereby the holder of each
               share of Series A Preferred Stock then outstanding shall
               have the right thereafter, during the period such share
               shall be convertible, to convert such share only into the
               kind and amount of securities, cash and other property
               receivable upon the reclassification, consolidation, merger,
               sale, transfer or share exchange by a holder of the number
               of shares of Common Stock of the Corporation into which a
               share of Series A Preferred Stock would have been
               convertible immediately prior to the reclassification,
               consolidation, merger, sale, transfer or share exchange.
               The Corporation, the person formed by the consolidation or
               resulting from the merger or which acquires such assets or
               which acquires the Corporation's shares, as the case may be,
               shall make provisions in its certificate or articles of
               incorporation or other constituent documents to establish
               such rights and to ensure that the dividend, voting and
               other rights of the holders of Series A Preferred Stock
               established herein are unchanged, except as permitted by
               Section 9 and applicable law.  The certificate or articles
               of incorporation or other constituent documents shall
               provide for adjustments, which, for events subsequent to the
               effective date of the certificate or articles of
               incorporation or other constituent documents, shall be as
               nearly equivalent as may be practicable to the adjustments
               provided for in this Section 7.  The provisions of this
               Section 7(c)(viii) shall similarly apply to successive
               reclassifications, consolidations, mergers, sales, transfers
               or share exchanges.

               (d)  Optional Reduction in Conversion Price.  The
Corporation may at its option reduce the Conversion Price from time to time
by any amount for any period of time if the period is at least 20 days and
if the reduction is irrevocable during the period.  Whenever the Conversion
Price is so reduced, the Corporation shall mail to holders of record of the
Series A Preferred Stock a notice of the reduction at least 15 days before
the date the reduced Conversion Price takes effect, stating the reduced
Conversion Price and the period it will be in effect.  A voluntary
reduction of the Conversion Price does not change or adjust the Conversion
Price otherwise in effect for purposes of Section 7(c).

               8. Status of Shares.  All shares of Series A Preferred Stock
that are at any time redeemed pursuant to Section 5 or converted pursuant to
Section 7 and all shares of Series A Preferred Stock that are otherwise
reacquired by the Corporation shall (upon compliance with any applicable
provisions of the laws of the State of Delaware) have the status of authorized
but unissued shares of Preferred Stock, without designation as to series,
subject to reissuance by the Board of Directors as shares of any one or more
other series.

               9. Voting Rights.

               (a) The holders of record of shares of Series A Preferred Stock
shall not be entitled to any voting rights except as hereinafter provided in
this Section 9 or as otherwise provided by law.

               (b) The holders of the shares of Series A Preferred Stock (i)
shall be entitled to vote with the holders of the Common Stock on all matters
submitted for a vote of holders of Common Stock (voting together with the
holders of Common Stock as one class), (ii) shall be entitled to a number of
votes equal to the number of votes to which shares of Common Stock issuable
upon conversion of such shares of Series A Preferred Stock would have been
entitled if such shares of Common Stock had been outstanding at the time of
the applicable vote and related record date and (iii) shall be entitled to
notice of any stockholders' meeting in accordance with the Certificate of
Incorporation and Bylaws of the Corporation.

               (c)  If and whenever six quarterly dividends (whether or not
consecutive) payable on the Series A Preferred Stock have not been paid in
full or if the Corporation shall have failed to discharge its Mandatory
Redemption Obligation on or after the Redemption Date, the number of directors
then constituting the Board of Directors shall be increased by two and the
holders of shares of Series A Preferred Stock, together with the holders of
shares of every other series of preferred stock upon which like rights to vote
for the election of two additional directors have been conferred and are
exercisable (resulting from either the failure to pay dividends or the failure
to redeem) (any such other series is referred to as the "Preferred Shares"),
voting as a single class regardless of series, shall be entitled to elect the
two additional directors to serve on the Board of Directors at any annual
meeting of stockholders or special meeting held in place thereof, or at a
special meeting of the holders of the Series A Preferred Stock and the
Preferred Shares called as hereinafter provided.  Whenever all arrears in
dividends on the Series A Preferred Stock and the Preferred Shares then
outstanding shall have been paid and dividends thereon for the current
quarterly dividend period shall have been paid or declared and set apart for
payment, or the Corporation shall have fulfilled its Mandatory Redemption
Obligation, as the case may be, then the right of the holders of the Series A
Preferred Stock and the Preferred Shares to elect such additional two
directors shall cease (but subject always to the same provisions for the
vesting of such voting rights in the case of any similar future arrearages in
six quarterly dividends or failure to fulfill any Mandatory Redemption
Obligation), and the terms of office of all persons elected as directors by
the holders of the Series A Preferred Stock and the Preferred Shares shall
forthwith terminate and the number of the Board of Directors shall be reduced
accordingly.  At any time after such voting power shall have been so vested in
the holders of shares of Series A Preferred Stock and the Preferred Shares,
the secretary of the Corporation may, and upon the written request of any
holder of Series A Preferred Stock (addressed to the secretary at the
principal office of the Corporation) shall, call a special meeting of the
holders of the Series A Preferred Stock and of the Preferred Shares for the
election of the two directors to be elected by them as herein provided, such
call to be made by notice similar to that provided in the Bylaws of the
Corporation for a special meeting of the stockholders or as required by law.
If any such special meeting required to be called as above provided shall not
be called by the secretary within 20 days after receipt of any such request,
then any holder of shares of Series A Preferred Stock may call such meeting,
upon the notice above provided, and for that purpose shall have access to the
stock records of the Corporation.  The directors elected at any such special
meeting shall hold office until the next annual meeting of the stockholders or
special meeting held in lieu thereof if such office shall not have previously
terminated as above provided.  If any vacancy shall occur among the directors
elected by the holders of the Series A Preferred Stock and the Preferred
Shares, a successor shall be elected by the Board of Directors, upon the
nomination of the then-remaining director elected by the holders of the Series
A Preferred Stock and the Preferred Shares or the successor of such remaining
director, to serve until the next annual meeting of the stockholders or
special meeting held in place thereof if such office shall not have previously
terminated as provided above.

               (d)  So long as any shares of Series A Preferred Stock are
outstanding:

                   (i) the Corporation shall not, without the written
         consent or affirmative vote at a meeting called for that purpose
         by holders of at least 66-2/3% of the outstanding shares of Series
         A Preferred Stock, voting as a single class, amend, alter or
         repeal any provision of the Corporation's Certificate of
         Incorporation (by merger or otherwise) so as to materially and
         adversely affect the preferences, rights or powers of the Series A
