      The purpose of the Corporation shall be to engage in any lawful act or
activity for which corporations may be organized and incorporated under the
General Corporation Law of the State of Delaware (the "GCL").

                                   ARTICLE IV

      (a) The total number of shares of stock which the Corporation shall have
authority to issue is Three Hundred and Fifty-Three Million (353,000,000),
consisting of Fifty-Three Million (53,000,000) shares of Preferred Stock, par

       (b) The Preferred Stock may be issued from time to time in one or more
series. The Board of Directors is hereby authorized to provide for the issuance
of shares of Preferred Stock in series and, by filing a certificate pursuant to
the applicable law of the State of Delaware ("Preferred Stock Designation"), to
establish from time to time the number of shares to be included in each such
series, and to fix the designation, powers, preferences and rights of the shares
of each such series and the qualifications, limitations and restrictions
thereof. The authority of the Board of Directors with respect to each series
shall include, but not be limited to, determination of the following:

            (1) The designation of the series, which may be by distinguishing
      number, letter or title.

            (2) The number of shares of the series, which number the Board of
      Directors may thereafter (except where otherwise provided in the Preferred
      Stock Designation) increase or decrease (but not below the number of
      shares thereof then outstanding).

            (3) Whether dividends, if any, shall be cumulative or noncumulative
      and the dividend rate of the series.


                                      -2-




            (4) The dates on which dividends, if any, shall be payable.

            (5) The redemption rights and price or prices, if any, for shares of
      the series.

            (6) The terms and amount of any sinking fund provided for the
      purchase or redemption of shares of the series.

            (7) The amounts payable on, and the preferences, if any, of, shares
      of the series in the event of any voluntary or involuntary liquidation,
      dissolution or winding up of the affairs of the Corporation.

            (8) Whether the shares of the series shall be convertible into
      shares of any other class or series, or any other security, of the
      Corporation or any other corporation, and, if so, the specification of
      such other class or series of such other security, the conversion price or
      prices or rate or rates, any adjustments thereof, the date or dates at
      which such shares shall be convertible and all other terms and conditions
      upon which such conversion may be made.

            (9) Restrictions on the issuance of shares of the same series or of
      any other class or series.

            (10) The voting rights, if any, of the holders of shares of the
      series.

      (c) The Common Stock shall be subject to the express terms of the
Preferred Stock and any series thereof. Each share of Common Stock shall be
equal to each other share of Common Stock. The holders of shares of Common Stock
shall be entitled to one vote for each such share upon all questions presented
to the stockholders.

      Except as may be provided in this Restated Certificate of Incorporation or
in a Preferred Stock Designation, or as may be required by law, the Common Stock
shall have the exclusive right to vote for the election of directors and for all
other purposes, and holders of Preferred Stock shall not be entitled to receive
notice of any meeting of stockholders at which they are not entitled to vote.

      (d) The Corporation shall be entitled to treat the person in whose name
any share of its stock is registered as the owner thereof for all purposes and
shall not be bound to recognize any equitable or other claim to, or interest in,
such share on the part of any other person, whether or not the Corporation shall
have notice thereof, except as expressly provided by applicable law.


                                      -3-




      (e) There shall be designated a series of the Corporation's Preferred
Stock, as follows:

            (1) Designation and Amount. The shares of such series shall be
      designated as "Series A Junior Participating Preferred Stock" (the "Series
      A Preferred Stock") and the number of shares constituting the Series A
      Preferred Stock shall be 3,000,000. Such number of shares may be increased
      or decreased by resolution of the Board of Directors; provided, that no
      decrease shall reduce the number of shares of Series A Preferred Stock to
      a number less than the number of shares then outstanding plus the number
      of shares reserved for issuance upon the exercise of outstanding options,
      rights or warrants or upon the conversion of any outstanding securities
      issued by the Corporation convertible into Series A Preferred Stock.

            (2) Dividends and Distributions.

            (a) Subject to the rights of the holders of any shares of any series
      of Preferred Stock (or any similar stock) ranking prior and superior to
      the Series A Preferred Stock with respect to dividends, the holders of
      shares of Series A Preferred Stock, in preference to the holders of Common
      Stock, and of any other junior stock, shall be entitled to receive, when,
      as and if declared by the Board of Directors out of funds legally
      available for the purpose, quarterly dividends payable in cash on the
      first day of March, June, September and December in each year (each such
      date being referred to herein as a "Quarterly Dividend Payment Date"),
      commencing on the first Quarterly Dividend Payment Date after the first
      issuance of a share or fraction of a share of Series A Preferred Stock, in
      an amount per share (rounded to the nearest cent) equal to the greater of
      (a) $1 or (b) subject to the provision for adjustment hereinafter set
      forth, 100 times the aggregate per share amount of all cash dividends, and
      100 times the aggregate per share amount (payable in kind) of all non-cash
      dividends or other distributions, other than a dividend payable in shares
      of Common Stock or a subdivision of the outstanding shares of Common Stock
      (by reclassification or otherwise), declared on the Common Stock since the
      immediately preceding Quarterly Dividend Payment Date or, with respect to
      the first Quarterly Dividend Payment Date, since the first issuance of any
      share of a fraction of a share of Series A Preferred Stock. In the event
      the Corporation shall at any time declare or pay any dividend on the
      Common Stock payable in shares of Common Stock, or effect a subdivision or
      combination or consolidation of the outstanding shares of Common Stock (by
      reclassification or otherwise than by payment of a dividend in shares of
      Common Stock) into a greater or lesser number of shares of Common Stock,
      then in each such case the amount to which holders of shares


                                      -4-



      of Series A Preferred Stock were entitled immediately prior to such
      event under clause (b) of the preceding sentence shall be adjusted by
      multiplying such amount by a fraction, the numerator of which is the
      number of shares of Common Stock outstanding immediately after such event
      and the denominator of which is the number of shares of Common Stock that
      were outstanding immediately prior to such event.

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

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

            (3) Voting Rights. The holders of shares of Series A Preferred Stock
      shall have the following voting rights:

            (a) Subject to the provision for adjustment hereinafter set forth,
      each share of Series A Preferred Stock shall entitle the holder thereof to
      100 votes on all matters submitted to a vote of the stockholders of the
      Corporation. In the


                                      -5-



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

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

            (c) Except as set forth herein, or as otherwise provided by law,
      holders of Series A Preferred Stock shall have no special voting rights
      and their consent shall not be required (except to the extent they are
      entitled to vote with holders of Common Stock as set forth herein) for
      taking any corporate action.

            (4)  Certain Restrictions.

            (a) Whenever quarterly dividends or other dividends or distributions
      payable on the Series A Preferred Stock as provided in paragraph (2) are
      in arrears, thereafter and until all accrued and unpaid dividends and
      distributions, whether or not declared, on shares of Series A Preferred
      Stock outstanding shall have been paid in full, the Corporation shall not:

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

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


                                      -6-



            then entitled;

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

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

            (b) The Corporation shall not permit any subsidiary of the
      Corporation to purchase or otherwise acquire for consideration any shares
      of stock of the Corporation unless the Corporation could, under
      subparagraph (a) of this paragraph (4), purchase or otherwise acquire such
      shares at such time and in such manner.

            (5) Reacquired Shares. Any shares of Series A Preferred Stock
      purchased or otherwise acquired by the Corporation in any manner
      whatsoever shall be retired and cancelled promptly after the acquisition
      thereof. All such shares shall upon their cancellation become authorized
      but unissued shares of Preferred Stock and may be reissued as part of a
      new series of Preferred Stock subject to the conditions and restrictions
      on issuance set forth herein, or in any other certificate of designations
      creating a series of Preferred Stock or any similar stock or as otherwise
      required by law.

            (6) Liquidation, Dissolution or Winding Up. Upon any liquidation,
      dissolution or winding up of the Corporation, no distribution shall be
      made (1) to the holders of shares of stock ranking junior (either as to
      dividends or upon liquidation, dissolution or winding up) to the Series A
      Preferred Stock unless, prior thereto, the holders of shares of Series A
      Preferred Stock shall have received $100 per share, plus an amount equal
      to all accrued and unpaid


                                      -7-



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

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


                                      -8-



      immediately prior to such event.

            (8) No Redemption. The shares of Series A Preferred Stock shall not
      be redeemable.

            (9) Rank. The Series A Preferred Stock shall rank, with respect to
      the payment of dividends and the distribution of assets, junior to all
      series of any other class of the Corporation's Preferred Stock.

            (10) Amendment. This Restated Certificate of Incorporation of the
      Corporation shall not be amended in any manner which would materially
      alter or change the powers, preferences or special rights of the Series A
      Preferred Stock so as to affect them adversely without the affirmative
      vote of the holders of at least two-thirds of the outstanding shares of
      Series A Preferred Stock, voting together as a single class.

                                    ARTICLE V

      The Board of Directors is hereby authorized to create and issue, whether
or not in connection with the issuance and sale of any of its stock or other
securities or property, rights entitling the holders thereof to purchase from
the Corporation shares of stock or other securities of the Corporation or any
other corporation. The times at which and the terms upon which such rights are
to be issued will be determined by the Board of Directors and set forth in the
contracts or instruments that evidence such rights. The authority of the Board
of Directors with respect to such rights shall include, but not be limited to,
determination of the following:

            (1) The initial purchase price per share or other unit of the stock
      or other securities or property to be purchased upon exercise of such
      rights.

            (2) Provisions relating to the times at which and the circumstances
      under which such rights may be exercised or sold or otherwise transferred,
      either together with or separately from, any other stock or other
      securities of the Corporation.

            (3) Provisions which adjust the number or exercise price of such
      rights or amount or nature of the stock or other securities or property
      receivable upon exercise of such rights in the event of a combination,
      split or recapitalization of any stock of the Corporation, a change in
      ownership of the Corporation's stock or other securities or a
      reorganization, merger, consolidation, sale of assets or other occurrence
      relating to the Corporation or any stock of the Corporation, and


                                      -9-



      provisions restricting the ability of the Corporation to enter into
      any such transaction absent an assumption by the other party or parties
      thereto of the obligations of the Corporation under such rights.

            (4) Provisions which deny the holder of a specified percentage of
      the outstanding stock or other securities of the Corporation the right to
      exercise such rights and/or cause the rights held by such holder to become
      void.

            (5) Provisions which permit the Corporation to redeem or exchange
      such rights.

            (6) The appointment of a rights agent with respect to such rights.

                                   ARTICLE VI

      In furtherance of, and not in limitation of, the powers conferred by law,
the Board of Directors is expressly authorized and empowered:

            (1) to adopt, amend or repeal the By-laws of the Corporation;
      provided, however, that the By-laws adopted by the Board of Directors
      under the powers hereby conferred may be amended or repealed by the Board
      of Directors or by the stockholders having voting power with respect
      thereto, provided further that in the case of amendments by stockholders,
      the affirmative vote of the holders of at least 80 percent of the voting
      power of the then outstanding Voting Stock (as defined below), voting
      together as a single class, shall be required to alter, amend or repeal
      any provision of the By-laws; and

            (2) from time to time to determine whether and to what extent, and
      at what times and places, and under what conditions and regulations, the
      accounts and books of the Corporation, or any of them, shall be open to
      inspection of stockholders; and, except as so determined or as expressly
      provided in this Restated Certificate of Incorporation or in any Preferred
      Stock Designation, no stockholder shall have any right to inspect any
      account, book or document of the Corporation other than such rights as may
      be conferred by applicable law.

      The Corporation may in its By-laws confer powers upon the Board of
Directors in addition to the foregoing and in addition to the powers and
authorities expressly conferred upon the Board of Directors by applicable law.
Notwithstanding anything contained in this Restated Certificate of Incorporation
to the contrary, the affirmative vote of the holders of at least 80 percent of
the voting power of the then outstanding Voting Stock, voting together as a
single class, shall be required to amend, repeal or


                                      -10-



adopt any provision inconsistent with paragraph (1) of this Article VI.
For the purposes of this Restated Certificate of Incorporation, "Voting Stock"
shall mean the outstanding shares of capital stock of the Corporation entitled
to vote generally in the election of directors.

                                   ARTICLE VII

      Subject to the rights of the holders of any series of Preferred Stock or
any other series or class of stock as set forth in this Restated Certificate of
Incorporation to elect additional directors under specific circumstances, any
action required or permitted to be taken by the stockholders of the Corporation
must be effected at a duly called annual or special meeting of stockholders of
the Corporation and may not be effected by any consent in writing in lieu of a
meeting of such stockholders. Notwithstanding anything contained in this
Restated Certificate of Incorporation to the contrary, the affirmative vote of
at least 80 percent of the voting power of the then outstanding Voting Stock,
voting together as a single class, shall be required to amend, repeal or adopt
any provision inconsistent with this Article VII.

                                  ARTICLE VIII

      Subject to the rights of the holders of any series of Preferred Stock or
any other series or class of stock as set forth in this Restated Certificate of
Incorporation to elect additional directors under specified circumstances, the
number of directors of the Corporation shall be fixed, and may be increased or
decreased from time to time, in such manner as may be prescribed by the By-laws
of the Corporation.

      Unless and except to the extent that the By-laws of the Corporation shall
so require, the election of directors of the Corporation need not be by written
ballot.

      The directors, other than those who may be elected by the holders of any
series of Preferred Stock or any other series or class of stock as set forth in
this Restated Certificate of Incorporation, shall be divided into three classes,
as nearly equal in number as possible. One class of directors shall be initially
elected for a term expiring at the annual meeting of stockholders to be held in
1999, another class shall be initially elected for a term expiring at the annual
meeting of stockholders to be held in 2000, and another class shall be initially
elected for a term expiring at the annual meeting of stockholders to be held in
2001. Members of each class shall hold office until their successors are elected
and qualified. At each succeeding annual meeting of the stockholders of the
Corporation, the successors of the class of directors whose term expires at that
meeting shall be elected by a plurality vote of all votes cast at such


                                      -11-



meeting to hold office for a term expiring at the annual meeting of
stockholders held in the third year following the year of their election.

      Subject to the rights of the holders of any series of Preferred Stock or
any other series or class of stock as set forth in this Restated Certificate of
Incorporation to elect additional directors under specified circumstances, any
director may be removed from office at any time by the stockholders, but only
for cause.

      Notwithstanding anything contained in this Restated Certificate of
Incorporation to the contrary, the affirmative vote of the holders of at least
80 percent of the voting power of the then outstanding Voting Stock, voting
together as a single class, shall be required to amend, repeal or adopt any
provision inconsistent with this Article VIII.

                                   ARTICLE IX

      Each person who is or was or has agreed to become a director or officer of
the Corporation, or each such person who is or was serving or who has agreed to
serve at the request of the Board of Directors or an officer of the Corporation
as an employee or agent of the Corporation or as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans (including
the heirs, executors, administrators or estate of such person), shall be
indemnified by the Corporation, in accordance with the By-laws of the
Corporation, to the fullest extent permitted from time to time by the GCL as the
same exists or may hereafter be amended (but, in the case of any such amendment,
only to the extent that such amendment permits the Corporation to provide
broader indemnification rights than said law permitted prior to such amendment)
or any other applicable laws as presently or hereafter in effect. Without
limiting the generality or the effect of the foregoing, the Corporation may
enter into one or more agreements with any person which provide for
indemnification greater than or different from that provided in this Article IX.
Any amendment or repeal of this Article IX shall not adversely affect any right
or protection existing hereunder in respect of any act or omission occurring
prior to such amendment or repeal.

                                    ARTICLE X

      A director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (1) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (2) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (3) under Section 174 of the GCL, or (4) for


                                      -12-



any transaction from which the director derived an improper personal
benefit. Any amendment or repeal of this Article X shall not adversely affect
any right or protection of a director of the Corporation existing hereunder in
respect of any act or omission occurring prior to such amendment or repeal.

                                   ARTICLE XI

      Except as may be expressly provided in this Restated Certificate of
Incorporation, the Corporation reserves the right at any time and from time to
time to amend, alter, change or repeal any provision contained in this Restated
Certificate of Incorporation or a Preferred Stock Designation, and any other
provisions authorized by the laws of the State of Delaware at the time in force
may be added or inserted, in the manner now or hereafter prescribed herein or by
applicable law, and all rights, preferences and privileges of whatsoever nature
conferred upon stockholders, directors or any other persons whomsoever by and
pursuant to this Restated Certificate of Incorporation in its present form or as
hereafter amended are granted subject to the right reserved in this Article XI;
provided, however, that any amendment or repeal of Article IX or Article X of
this Restated Certificate of Incorporation shall not adversely affect any right
or protection existing hereunder in respect of any act or omission occurring
prior to such amendment or repeal; and provided further that no Preferred Stock
Designation shall be amended after the issuance of any shares of the series of
Preferred Stock created thereby, except in accordance with the terms of such
Preferred Stock Designation and the requirements of applicable law.

      IN  WITNESS  WHEREOF,  W.  R.  Grace  & Co.  has  caused  this  Restated
Certificate  of  Incorporation  to be signed by its Senior Vice President this
3rd day of April, 1998.
