ITEM 5. OTHER EVENTS.


       On August 14, 1997, Sealed Air Corporation, a Delaware corporation
("Sealed Air"), W. R. Grace & Co., a Delaware corporation, ("Grace") and
Packco Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary
of Grace ("Merger Sub"), entered into an Agreement and Plan of Merger (the
"Merger Agreement").  Pursuant to the Merger Agreement and related agreements
and subject to the terms and conditions set forth therein, Grace will
contribute its specialty chemicals and other businesses (other than its
packaging business) to a newly formed wholly-owned subsidiary of Grace ("New
Grace"), which will be spun off to the shareholders of Grace (the "Spinoff"),
leaving Grace with only its packaging business ("Packaging").  Grace's
subsidiary, Merger Sub, will then merge with and into Sealed Air, with Sealed
Air to be the surviving corporation (the "Merger").  Immediately following the
Merger, Grace will be renamed "Sealed Air Corporation" to create a new
publicly owned company ("New Sealed Air").

       Immediately prior to the Merger, the outstanding shares of Grace common
stock, par value $.01 per share, will be recapitalized into an aggregate of
40.895 million shares of common stock, par value $.10 per share, of New Sealed
Air ("New Sealed Air Common Stock") (subject to adjustment in certain events)
and 36 million shares of a new series of convertible preferred stock, par
value $.10 per share, of New Sealed Air.  In the Merger, Sealed Air
shareholders will receive one share of New Sealed Air Common Stock for each
share of Sealed Air common stock, par value $.01 per share, held immediately
prior to the Merger.  On a fully-diluted basis and immediately after the
Merger, former Sealed Air shareholders will own 37% of the equity of New
Sealed Air and former Grace shareholders will own, in the aggregate,
approximately 63%.

       Prior to the Spin-off, New Grace will receive approximately $1.2
billion from Packaging and Grace (the "Contribution").   The indebtedness
incurred in connection with the Contribution will remain an obligation of New
Sealed Air and Packaging following the Merger.

       Sealed Air and Grace have issued a joint press release regarding the
foregoing, which is attached hereto as an exhibit.

       The foregoing is qualified in its entirety by reference to the Merger
Agreement; the Form of the Distribution Agreement by and among Grace, W. R.
Grace & Co.-Conn. ("Grace-Conn.") and Grace Specialty Chemicals, Inc. ("Grace
Chemicals"); the Form of Employee Benefits Allocation Agreement by and among
Grace, Grace-Conn. and Grace Chemicals; and the Form of Tax Sharing Agreement
by and among Sealed Air, Grace and Grace-Conn. that are attached hereto as
exhibits and are incorporated by reference herein.

                   AGREEMENT AND PLAN OF MERGER, dated as of August 14,
1997 (this "Agreement"), by and among W.  R.  GRACE & CO., a Delaware
corporation ("Grace"), Packco Acquisition Corp., a Delaware corporation and
a wholly-owned subsidiary of Grace ("Merger Sub"), and Sealed Air
Corporation, a Delaware corporation ("Sealed Air").


                                 RECITALS
                                 --------

            A.  Defined Terms.  Certain capitalized terms used herein shall
have the meanings set forth in Annex A hereto.

            B.  The Contribution.  Prior to the Effective Time, and pursuant
to the Distribution Agreement, a form of which is attached hereto as Exhibit A
(the "Distribution Agreement"), Grace intends to contribute (the
"Contribution") its worldwide packaging business (other than the container
business group) to an indirect, newly-formed Delaware subsidiary of Grace
("Packco").

            C.  The Distribution.  Prior to the Effective Time, Grace, New
Grace (as defined in the Distribution Agreement) and W. R. Grace & Co.-Conn.
("Grace-Conn.") intend to consummate the transactions contemplated by the
Distribution Agreement, including the distribution by Grace to the holders of
Grace Common Shares all of the common stock of New Grace (the "Distribution").

            D.  The Recapitalization.  Immediately prior to the Effective
Time, but following the Distribution, Grace shall be recapitalized (as defined
in the Distribution Agreement, the "Recapitalization") so that the holders of
Grace Common Shares shall thereafter hold Newco Common Shares and Newco
Convertible Preferred Shares, all as provided in the Distribution Agreement.

            E.  The Merger.  At the Effective Time, the parties intend to
effect a merger of Merger Sub with and into Sealed Air, with Sealed Air being
the surviving corporation (the "Merger"), the Certificate of Incorporation of
Sealed Air shall be amended to change the name of Sealed Air to a different
name as determined by Sealed Air, and the Certificate of Incorporation of
Grace shall be amended (the "Newco Amendment") to change the name of Grace to
"Sealed Air Corporation" (such corporation, from and after the Effective Time,
is sometimes hereinafter referred to as "Newco") and to effect the other
amendments described in Exhibit F hereto.

            F.  Intention of the Parties.  It is the intention of the parties
to this Agreement that, for United States federal income tax purposes, the
Distribution, Recapitalization and related transactions shall be tax-free to
Grace and its shareholders under the Code and the Merger shall qualify as a
"reorganization" within the meaning of Section 368 of the Code and the Merger
will be tax-free under the Code to Grace, Sealed Air and their respective
shareholders.

            G.  Approvals.  The Board of Directors of each party hereto has
determined that this Agreement is in the best interests of such party and its
shareholders and has duly approved this Agreement and authorized its execution
and delivery.

            NOW, THEREFORE, in consideration of the premises, and of the
representations, warranties, covenants and agreements set forth herein, the
parties hereto hereby agree as follows:

(the "Surviving Corporation") and shall continue to be governed by the laws of

the Merger Certificate has been duly  filed with the Secretary of State of the
State of Delaware, or at such later date and time as set forth therein.

            1.4.  Closing.  The closing of the Reorganization (the "Closing")

            2.2.  Surviving Corporation By-laws.  The By-laws of Merger Sub,

                                ARTICLE IV

                    MERGER CONSIDERATION; CONVERSION OR
                   CANCELLATION OF SHARES IN THE MERGER

            4.1.  Merger Consideration; Conversion or Cancellation of Capital
Stock of Sealed Air and Merger Sub.  At the Effective Time, by virtue of the
Merger and without any action on the part of the holder of any capital stock
of Sealed Air or Merger Sub:

            (a)  Each Sealed Air Common Share issued and outstanding
      immediately prior to the Effective Time (other than any Sealed Air
      Common Share owned by Grace or its subsidiaries or any Sealed Air
      subsidiary or held in Sealed Air's treasury) shall be converted into and
      become at the Effective Time one Newco Common Share.

            (b)  Each Newco Common Share and each Newco Convertible Preferred
      Share issued and outstanding immediately prior to the Effective Time
      shall remain issued and outstanding and shall be unchanged by the Merger.

            (c)  All Sealed Air Common Shares shall cease to be outstanding,
      shall be cancelled and retired and shall cease to exist.

            (d)  Each Sealed Air Common Share issued and outstanding
      immediately prior to the Effective Time and owned by Grace or its
      subsidiaries or any Sealed Air subsidiary or held in Sealed Air's
      treasury shall cease to be outstanding, shall be cancelled and retired
      without payment of any consideration therefor and shall cease to exist.

            (e)  Each share of Merger Sub Common Stock issued and outstanding
      immediately prior to the Effective Time shall be converted into and
      become one share of common stock of the Surviving Corporation.

            4.2.  Exchange of Old Certificates for New Certificates.  (a)
Appointment of Exchange Agent.  From and  after the Effective Time until the
end of the six-month period following the Effective Time, Newco shall make
available or cause to be made available to an exchange agent appointed prior
to the Effective Time with the approval of each of Grace and Sealed Air (the
"Exchange Agent") Newco Certificates in amounts sufficient to allow the
Exchange Agent to make all deliveries of Newco Certificates that are requested
by holders of Old Sealed Air Certificates in exchange for Old Sealed Air
Certificates pursuant to this Article IV.  In its discretion, Newco may elect
to evidence ownership of Newco Common Shares through a book-entry transfer
agent, in which case the Exchange Agent shall deliver, upon compliance by a
former Sealed Air shareholder with the provisions of Section 4.2(b), a
book-entry account statement evidencing the ownership of Newco Common Shares
(or, at the request of a former Sealed Air shareholder, a Newco Certificate
evidencing such ownership).  In the event Newco so elects, references herein
to Newco Certificates shall be deemed to include references to the book-entry
account statements relating to the ownership of Newco Common Shares.

            (b)  Exchange Procedures.  Promptly after the Effective Time,
Newco shall cause the Exchange Agent to mail or deliver to each person who
was, at the Effective Time, a holder of record of Sealed Air Common Shares a
letter of transmittal (the terms of which shall be mutually agreed upon by the
parties hereto prior to the Effective Time) containing instructions for use by
holders of Sealed Air Common Shares who may, in their discretion, desire to
surrender their Old Sealed Air Certificates in exchange for Newco Certificates
pursuant to this Article IV.  Upon surrender to the Exchange Agent of an Old
Sealed Air Certificate for cancellation together with such letter of
transmittal, duly executed and completed in accordance with the instructions
thereto, the holder of such Old Sealed Air Certificate shall be entitled to
receive in exchange therefor a Newco Certificate representing the Newco Common
Shares and the Old Sealed Air Certificate so surrendered shall forthwith be
cancelled.  If any Newco Certificate is to be issued in a name other than that
in which the Old Sealed Air Certificate surrendered in exchange therefor is
registered, it shall be a condition of such exchange that the person
requesting such exchange shall pay any transfer or other taxes required by
reason of the issuance of such in a name other than that of the registered
holder of the Old Sealed Air Certificate surrendered, or shall establish to
the satisfaction of Newco that any such taxes have been paid or are not
applicable.  Six months after the Effective Time, Newco shall be entitled to
cause the Exchange Agent to deliver to it any applicable Newco Certificates
made available to the Exchange Agent that are unclaimed by the former
shareholders of Sealed Air.  Any such former shareholders who have not
theretofore exchanged their  Old Sealed Air Certificates for Newco
Certificates pursuant to this Article IV who desires to do so shall thereafter
be entitled to look exclusively to Newco and only as general creditors thereof
to obtain Newco Certificates to which they become entitled upon exchange of
their Old Sealed Air Certificates pursuant to this Article IV.  Newco shall
pay all applicable charges and expenses in connection with the exchange of
Newco Certificates for Old Sealed Air Certificates as contemplated hereby.

            (c)  No Transfers.  At or after the Effective Time, there shall be
no transfers on the stock transfer books of the Surviving Corporation of
Sealed Air Common Shares which were outstanding immediately prior to the
Effective Time.

            (d)  No Liability.  If any Old Sealed Air Certificate shall have
been lost, stolen or destroyed, upon the making of an affidavit of that fact
by the person claiming such Certificate to be lost, stolen or destroyed and,
if required by Newco, the posting by such person of a bond in such reasonable
amount as Newco may direct as indemnity against any claim that may be made
against it with respect to such Old Sealed Air Certificate, Newco shall, in
exchange for such lost, stolen or destroyed Old Sealed Air Certificates, issue
or cause to be issued the Newco Certificate deliverable in respect thereof
pursuant to this Article IV.  No party hereto, nor the Exchange Agent, shall be
liable to any holder of former Sealed Air Common Shares for any cash delivered
to a public official pursuant to any applicable abandoned property, escheat or
similar law.

            (e)  Withholding Rights.  Newco shall be entitled to deduct and
withhold from the consideration otherwise payable pursuant to this Agreement
to any holder of former Sealed Air Common Shares such amounts as may be
required to be deducted and withheld with respect to the making of such
payment under the Code, or under any provision of state, local or foreign tax
law.  To the extent that amounts are so withheld and paid over to the
appropriate taxing authority, such withheld amounts shall be treated for all
purposes of this Agreement as having been paid to the holder of the former
Sealed Air Common Shares in respect of which such deduction and withholding
was made.

            (f)  Sealed Air Contingent Stock and Restricted Stock Plans.  The
Sealed Air Stock Plans shall be amended in accordance with their terms and
applicable law, with the effect that as of the Effective Time, among other
things, (i) all of the rights and obligations of Sealed Air under the Sealed
Air Stock Plans, including with respect to awards outstanding at the Effective
Time, shall be rights and obligations of Newco following the Effective Time
and (ii) each unexercised right granted  under the Sealed Air Stock Plans to
purchase a Sealed Air Common Share shall constitute a right to purchase a
Newco Common Share in accordance with the terms and conditions of the
applicable Sealed Air Stock Plans, as amended from time to time.


                                 ARTICLE V

                      REPRESENTATIONS AND WARRANTIES

            5.1.  Representations and Warranties of Grace.  Grace hereby
represents and warrants to Sealed Air that, except as set forth in a letter
delivered to Sealed Air simultaneously with the execution and delivery of this
Agreement (the "Grace Disclosure Letter"):

            (a)  Capital Stock.  (i)  Grace.  The authorized capital stock of
      Grace consists of 300,010,165 Grace Common Shares, par value $.01 per
      share, of which 73,409,932 were outstanding as of August 1, 1997, and
      53,000,000 Grace Preferred Shares, par value $.01 per share, of which,
      as of August 1, 1997, none was outstanding.  As of August 1, 1997,
      6,224,234 Grace Common Shares were held in the treasury of Grace.  As of
      the Effective Time, there will be no Grace Common Shares held in the
      treasury of Grace.  As of August 1, 1997, there were outstanding under
      the Grace 1996 Stock Incentive Plan, the Grace 1994 Stock Incentive Plan,
      the Grace 1989 Stock Incentive Plan, the Grace 1986 Stock Incentive
      Plan, the Grace 1981 Stock Incentive Plan, and the Grace 1997 Stock
      Retainer Plan for Nonemployee Directors and any other plan for employees
      or directors of Grace (collectively, the "Grace Stock Plans") options to
      acquire an aggregate of 5,655,954 Grace Common Shares (subject to
      adjustment on the terms set forth in the Grace Stock Plans) at an
      average exercise price of $34.65 per share (the "Grace Options").  Such
      Grace Options include options to acquire an aggregate of 669,887 Grace
      Common Shares at an average exercise price of $40.81 per share held by
      Packco Employees (based on information regarding the identity of such
      employees as of the date hereof and as defined in the Benefits
      Agreement).  As of August 1, 1997, there were no shares of capital stock
      of Grace reserved for issuance, other than 3,000,000 Grace Preferred
      Shares reserved for issuance in connection with the Grace Rights and
      12,189,285 Grace Common Shares reserved for issuance under the Grace
      Stock Plans.  All outstanding Grace Common Shares have been duly
      authorized and validly issued and are fully paid and nonassessable, and
      all Grace Common Shares issuable under the Grace Stock Plans have been
      duly authorized and will, upon issuance in accordance  with the Grace
      Stock Plans and any agreements thereunder, be validly issued, fully paid
      and nonassessable.  Except for the Grace Common Shares, Grace has
      outstanding no bonds, debentures, notes or other obligations or
      securities the holders of which have the right to vote (or are
      convertible or exchangeable into or exercisable for securities having the
      right to vote) with the shareholders of Grace on any matter.  Except as
      set forth above, except for Grace Common Shares issued after August 1,
      1997 pursuant to the terms of options, securities or plans referred to
      above and except in connection with the Transaction Agreements, there
      are no shares of capital stock of Grace authorized, issued or
      outstanding and there are no preemptive rights or any outstanding
      subscriptions, options, puts, calls, warrants, rights, convertible or
      exchangeable securities or other agreements or commitments of Grace or
      any of its subsidiaries of any character relating to the issued or
      unissued capital stock or other securities of Grace or any of its
      subsidiaries (including, without limitation, the issuance, sale,
      purchase, redemption, conversion, exchange, redemption, voting or
      transfer thereof).  The Newco Common Shares to be issued in the
      Recapitalization and the Merger or upon exercise of the Grace Options
      after the Recapitalization and the Newco Preferred Shares to be issued
      in the Recapitalization will, upon such issuance, be duly authorized,
      fully paid, validly issued and nonassessable.

          (ii)  Merger Sub.  The authorized capital stock of Merger Sub
      consists of 1,000 shares of common stock, par value $.01 per share,
      of Merger Sub (the "Merger Sub Common Stock").  As of the date of
      this Agreement, 1,000 shares of Merger Sub Common Stock are issued
      and outstanding, all of which are duly authorized, validly issued,
      fully paid and nonassessable.  Each issued and outstanding share of
      Merger Sub Common Stock is owned by Grace, free and clear of all
      liens, pledges, security interests, claims, proxies, preemptive or
      subscriptive rights and or other encumbrances or restrictions of any
      kind.  No shares of Merger Sub Common Stock are held in the treasury
      of Merger Sub.  There are no options, warrants or other rights,
      agreements, arrangements or commitments of any character relating to
      the issued or unissued capital stock of Merger Sub or obligating
      Grace or any of its subsidiaries to issue or sell any shares of
      capital stock, or other equity interest in, Merger Sub.  As of the
      Effective Time, all of the outstanding shares of capital stock of the
      Surviving Corporation will be duly authorized, validly issued, fully
      paid and nonassessable, and will be owned by Grace, free and clear of
      all liens, pledges, security interests, claims, proxies, preemptive
      or subscriptive rights and or other encumbrances or restrictions of
      any kind.  Merger Sub was formed for the purpose of effecting the
      Merger and has no other business activity.

            (b)  Corporate Organization and Qualification.  Each of Grace and
      Merger Sub is a corporation duly organized, validly existing and in good
      standing under the laws of Delaware and is in good standing (if
      recognized in such jurisdiction, or, if not, duly qualified) as a foreign
      corporation in each jurisdiction where the properties owned, leased or
      operated, or the business conducted, by it or its subsidiaries require
      such qualification, except for any such failure so to qualify or be in
      good standing which, when taken together with all other such failures, is
      not reasonably likely to have a Material Adverse Effect with respect to
      Grace.  Each of Grace and Merger Sub has the requisite corporate power
      and authority and all material governmental licenses and approvals to
      carry on its businesses as they are now being conducted.  Grace has made
      available to Sealed Air a complete and correct copy of the Certificate
      of Incorporation and By-laws of Grace and Merger Sub, each as amended to
      date and currently in full force and effect.

            (c)  Corporate Authority.  Subject only to the receipt of the
      requisite approval of its shareholders necessary to consummate the
      Reorganization, each of Grace, Merger Sub and each other subsidiary of
      Grace that is or will be a party to a Transaction Agreement has the
      requisite corporate power and authority and has taken all corporate
      action necessary in order to execute, deliver and perform each
      Transaction Agreement to which it is a party and to consummate the
      transactions contemplated hereby and thereby, including, without
      limitation, the approval of the Grace Board and the resolution of the
      Grace Board to recommend, subject to their fiduciary duties, the
      transactions contemplated hereby and thereby for approval by Grace
      shareholders.  Each Transaction Agreement to which Grace, Merger Sub or
      any of Grace's subsidiaries is a party is, or when executed and
      delivered shall be, a valid and binding agreement of such person
      enforceable in accordance with its terms.  The affirmative votes of the
      holders of a majority of the outstanding Grace Common Shares in favor of
      the Merger and related transactions (including the amendments to the
      Grace Certificate of Incorporation) and the Distribution are the only
      votes of the holders of Grace's capital stock necessary in connection
      with the consummation of the Reorganization.

            (d)  Governmental Filings; No Violations.  (i)  Other than as may
      be required under the HSR Act and similar statutes in other countries,
      the Exchange Act, the Securities Act, state securities laws, no notices,
      reports or other filings are required to be made by Grace or any Grace
      subsidiary with, nor are any consents, registrations, approvals, permits
      or authorizations required to be obtained by it or any such subsidiary
      from, any governmental or regulatory authority, agency, court,
      commission or other entity, domestic or foreign ("Governmental Entity"),
      in connection with the execution, delivery or performance of each
      Transaction Agreement to which it or any such subsidiary is a party and
      the consummation by it or any such subsidiary of the transactions
      contemplated hereby and thereby, except for such matters as would not,
      individually or in the aggregate, have a Material Adverse Effect with
      respect to the New Grace Group or the Packco Group or prevent or
      materially delay or enable any person to enjoin consummation of the
      transactions contemplated hereby and thereby.

            (ii)  The execution, delivery and performance by Grace or any
      Grace subsidiary of each Transaction Agreement to which it is a party
      does not or will not, and the consummation by it of any of the
      transactions contemplated hereby and thereby will not, constitute or
      result in (with or without the giving of notice, the lapse of time or
      both) (A) a breach or violation of, or a default under, its certificate
      of incorporation or by-laws or comparable governing instruments, or (B)
      a breach or violation of, or a default under, or an acceleration or
      termination of or change in the rights or obligations of any party
      under, or the creation of a lien, pledge, security interest or other
      encumbrance on any assets pursuant to, any provision of any agreement,
      lease, contract, note, mortgage, indenture, arrangement or other
      obligation or commitment ("Contracts") of it or any of its subsidiaries
      or any law, rule, ordinance or regulation or judgment, decree, order,
      award or governmental or non-governmental permit or license to which it
      or any of its subsidiaries is subject, except, in the case of clause (B)
      above, for such breaches, violations, defaults, accelerations or changes
      that are disclosed in the Grace Disclosure Letter or, individually or
      in the aggregate, are not reasonably likely to have a Material Adverse
      Effect with respect to the New Grace Group or the Packco Group or
      prevent or materially delay or enable any person to enjoin consummation
      of the Reorganization.

            (e)  SEC Documents; Financial Statements; No Undisclosed
      Liabilities.  (i)  Grace has filed all forms, reports and documents
      required to be filed by it under the Exchange Act or the Securities Act
      since December 31, 1994.  As of its filing date, each SEC Document
      filed, and each SEC Document that will be filed by it or its subsidiaries
      prior to the Effective Time, as amended or supplemented, if applicable,
      pursuant to the Exchange Act or the Securities Act (A) complied or will
      comply in all material respects with the applicable requirements of the
      Exchange Act or the Securities Act and (B) did not or will not contain
      any untrue statement of a material fact or omit to state any material
      fact necessary in order to make the statements made therein, in the
      light of the circumstances under which they were made, not misleading.
      Each of Grace's consolidated balance sheets included in or incorporated
      by reference into its SEC Documents (including the related notes and
      schedules) fairly presents in all material respects the consolidated
      financial position of it and its subsidiaries as of the dates set forth
      therein and each of the consolidated statements of operations, cash
      flows and shareholders' equity included in or incorporated by reference
      into its SEC Documents (including any related notes and schedules)
      fairly presents in all material respects the consolidated results of
      operations, cash flows and retained earnings, as the case may be, of it
      and its subsidiaries for the periods set forth therein (subject, in the
      case of unaudited statements, to normal year-end audit adjustments), in
      each case in accordance with US GAAP (applied on a consistent basis).

          (ii)    Except as disclosed in its SEC Documents filed with the SEC
      prior to the date hereof, neither Grace nor any of its subsidiaries has
      any liabilities of any kind whatsoever, whether or not accrued,
      contingent or otherwise, that, individually or in the aggregate, are
      reasonably likely to have a Material Adverse Effect with respect to the
      Packco Group or the New Grace Group.

            (f)   Absence of Certain Events and Changes.  Except (i) as
      disclosed in its SEC Documents filed with the SEC prior to the date
      hereof, and (ii) as contemplated by the Transaction Agreements, since
      December 31, 1996, Grace and its subsidiaries have conducted their
      respective businesses only in the ordinary and usual course of such
      businesses, and there has not been any change or development or
      combination of changes or developments (including any worsening of any
      condition currently existing) which, individually or in the aggregate,
      is reasonably likely to  result in a Material Adverse Effect with
      respect to the New Grace Group.

            (g)  Takeover Statutes; Rights Plan.  The execution, delivery and
      performance of this Agreement and consummation of the transactions
      contemplated hereby will not cause to  be applicable to Grace, Section
      203 of the DGCL or any similar provision (a "Takeover Statute") (after
      giving effect to any actions that will be taken prior to the Effective
      Time).  The Grace Board has taken, or prior to the Effective Time will
      take, all requisite action in order to amend the Grace Rights Agreement
      so as to render the Grace Rights inapplicable to the Merger, the
      Recapitalization, and the Distribution and to terminate or redeem the
      Grace Rights at or prior to the Effective Time.

            (h)  Brokers and Finders.  Neither Grace nor any of its
      subsidiaries or any of their respective officers, directors or employees
      has employed any broker or finder or incurred any liability for any
      brokerage fees, commissions or finders' fees in connection with the
      transactions contemplated herein, except pursuant to arrangements
      disclosed in writing to the other parties hereto prior to the date
      hereof.

            (i)  Contribution.  The Packco Assets represent the worldwide
      Packaging Business of Grace and its subsidiaries and all of their assets
      used or held for use in the conduct of Grace's worldwide Packaging
      Business as presently conducted or as conducted at the Effective Time,
      as the case may be.

            (j)  Tax Matters.  Except as reflected in its SEC Documents filed
      with the SEC prior to the date hereof and except for such matters that,
      individually or in the aggregate, are not reasonably likely to have a
      Material Adverse Effect with respect to the Packco Group or the New
      Grace Group:  (i) all federal, state, local and foreign tax returns
      required to be filed by or on behalf of Grace or any of its subsidiaries
      have been timely filed, or requests for extensions have been timely
      filed and have been granted and have not expired, and all such filed
      returns are complete and accurate in all respects; (ii) all taxes shown
      as due and payable on returns filed by Grace or any of its subsidiaries
      have been paid in full; (iii) there is no outstanding audit examination,
      deficiency or refund litigation with respect to any taxes of Grace; (iv)
      all taxes, interest, additions, and penalties due with respect to
      completed and settled examinations or concluded litigation relating to
      Grace have been paid in full or have been  recorded as a liability on
      its balance sheet (in accordance with US GAAP); (v) neither Grace nor
      any of its subsidiaries is a party to any tax sharing or similar
      agreement pursuant to which it or any of its subsidiaries has
      indemnified another party with respect to taxes; and (vi) neither Grace
      nor any of its subsidiaries has waived any applicable statute of
      limitations with respect to any taxes.  At the Effective Time, the
      representations set forth in the Tax Matters Certificates of Grace-Conn.,
      substantially in the form of Exhibit B (the "Grace Tax Matters
      Certificate"), will be true and correct in all respects, and such
      representations are hereby incorporated herein by reference with the
      same effect as if set forth herein in their entirety.

            (k)  Disclosure.  The representations and warranties of Grace
      contained in this Agreement or in any written instrument, exhibit or
      certificate furnished or to be furnished by Grace to Sealed Air pursuant
      hereto or in connection herewith, do not contain any untrue statement of
      a material fact or omit to state a material fact necessary in order to
      make the statements contained therein not misleading.

            5.2.  Representations and Warranties for the Packaging Business.
Grace hereby represents and warrants to Sealed Air that, except as set forth
in a letter delivered to Sealed Air simultaneously with the execution and
delivery of this Agreement (the "Packaging Business Disclosure Letter"):

            (a)  Corporate Organization and Qualification.  At the Effective
      Time, Packco and each Packco Subsidiary will be duly organized, validly
      existing and in good standing under the laws of its jurisdiction of
      organization and will be in good standing (if recognized in such
      jurisdiction, or, if not, duly qualified) as a foreign corporation in
      each jurisdiction where the properties owned, leased or operated, or the
      business conducted, by Packco or such Packco Subsidiary require such
      qualification, except for any such failure so to qualify or be in good
      standing which, when taken together with all other such failures, is not
      reasonably likely to have a Material Adverse Effect with respect to the
      Packco Group or the Packaging Business.  At the Effective Time, Packco
      and each Packco Subsidiary will have the requisite corporate power and
      authority and all material governmental licenses and approvals to carry
      on its business as now being conducted.

            (b)  Corporate Authority.  At the Effective Time, Packco and each
      Packco Subsidiary will have the requisite  corporate power and authority
      and will have taken all corporate action necessary in order to
      consummate the transactions contemplated hereby and by the other
      Transaction Agreements.

            (c)  Capitalization.  All issued and outstanding shares of capital
      stock of Packco and each Packco Subsidiary (except for an immaterial
      number of shares held by officers and directors of Grace and its
      subsidiaries as required by applicable law) will, as of the Effective
      Time, be owned of record and beneficially by Grace, Packco or another
      Packco Subsidiary, free and clear of all liens, pledges, security
      interests, claims, proxies, preemptive or subscriptive rights or other
      encumbrances or restrictions of any kind.  There are no options,
      warrants or other rights, agreements, arrangements or commitments of any
      character relating to the issued or unissued capital stock of Packco or
      any Packco Subsidiary or obligating Packco or any Packco Subsidiary to
      issue or sell any shares of capital stock of, or other equity interests
      in, Packco or any Packco Subsidiary.  There are no outstanding
      contractual obligations of Packco or any Packco Subsidiary to
      repurchase, redeem or otherwise acquire any capital stock of Packco or
      any Packco Subsidiary or to provide funds to make any investment (in the
      form of a loan, capital contribution or otherwise) in Packco or any
      Packco Subsidiary or any other entity.  As of the Effective Time, each
      of the outstanding shares of capital stock of Packco, and each Packco
      Subsidiary will be duly authorized, validly issued, fully paid and
      nonassessable.

            (d)  Financial Statements; No Undisclosed Liabilities.  (i)
      Included in the Packaging Business Disclosure Letter are unaudited
      special purpose consolidated and combined balance sheets as of December
      31, 1995 and 1996 and June 30, 1997, and special purpose consolidated
      and combined statements of earnings before interest and taxes for the
      three years ended December 31, 1996 and the six months ended June 30,
      1997 for the Packaging Business (such financial statements, the
      "Packaging Business Disclosure Letter Financial Statements," and the
      balance sheet as of December 31, 1996 included therein, the "Packaging
      Business Disclosure Letter Balance Sheet").  The balance sheets included
      in the Packaging Business Disclosure Letter Financial Statements
      (including and subject to the Basis of Presentation) fairly present in
      all material respects, and the special purpose consolidated and combined
      balance sheet to be included in the Packaging Business Financial
      Statements (including any related notes and schedules) shall fairly
      present in all material respects,  the consolidated financial position
      of the Packaging Business, in each case as of the dates set forth
      therein; and each of the special purpose consolidated and combined
      statements of earnings before interest and taxes included in the
      Packaging Business Disclosure Letter Financial Statements (including and
      subject to the Basis of Presentation) fairly presents in all material
      respects, and each consolidated statement of operations, cash flows and
      shareholders' equity to be included in the Packaging Business Financial
      Statements (including any related notes and schedules) shall fairly
      present in all material respects, the consolidated results of

      Packaging Business for the periods set forth therein, in each case in
      accordance with US GAAP applied on a consistent basis (subject, in the
      case of interim financial statements, to normal year-end adjustments).

          (ii)  Except as disclosed on the Packaging Business Disclosure
      Letter Balance Sheet or in the Basis of Presentation thereto, the
      Packco Group does not have any liabilities of any kind whatsoever,
      whether or not accrued, contingent or otherwise, that, individually
      or in the aggregate, are reasonably likely to have a Material Adverse
      Effect with respect to the Packco Group or the Packaging Business
      (other than liabilities to be incurred in connection with the Grace
      Credit Agreement).

            (e)  Absence of Certain Events and Changes.  Except (i) as
      disclosed in the Packaging Business Disclosure Letter, and (ii) as
      contemplated by the Transaction Agreements, since December 31, 1996, the
      Packaging Business has been conducted only in the ordinary and usual
      course of business and there has not been any change or development or
      combination of changes or developments (including any worsening of any
      condition currently existing) which, individually or in the aggregate,
      is reasonably likely to result in a Material Adverse Effect with respect
      to the Packco Group or the Packaging Business.

            (f)  Compliance with Laws.  Grace and its subsidiaries (with
      respect to the Packaging Business) have complied with all applicable
      federal, state, local and foreign statutes, laws, regulations,
      ordinances, rules, judgments, orders or decrees applicable thereto,
      except where the failure to comply is not reasonably likely,
      individually and in the aggregate, to have a Material Adverse Effect
      with respect to the Packco Group or the Packaging Business.  Grace and
      its subsidiaries (with respect to the  Packaging Business) have, and
      immediately after the Contribution will have, all permits, licenses,
      certificates of authority, orders, and approvals of, and has and will
      have made all filings, applications, and registrations with, federal,
      state, local, and foreign Governmental Entities that are required in
      order to permit the Packco Group to carry on the Packaging Business as
      it is presently conducted by Grace and its subsidiaries, except for such
      permits, licenses, certificates, orders, filings, applications and
      registrations, the failure to have or make which, individually or in the
      aggregate, are not reasonably likely to have a Material Adverse Effect
      with respect to the Packco Group or the Packaging Business.

            (g)  Title to Assets.  Effective as of the Distribution Date and
      subject to the provisions of Article II of the Distribution Agreement or
      as disclosed in the Packaging Business Disclosure Letter, one or more
      members of the Packco Group will:

                  (i)   have good and valid title to the Packco Assets (as
            defined in the Distribution Agreement) (including, without
            limitation, all assets reflected on the Packaging Business
            Disclosure Letter Balance Sheet or Packco Assets acquired after
            December 31, 1996, except for such assets as were sold since
            December 31, 1996 in the ordinary course of business and not in
            violation of this Agreement), free and clear of any Liens; and

                  (ii)  own or have adequate rights to use all assets used or
            held for use in the Packaging Business as conducted by Grace and
            its subsidiaries as of the Distribution Date, and such rights are
            sufficient to permit the Packco Group to continue to operate the
            Packaging Business as conducted by Grace and its subsidiaries as
            of the Distribution Date;

      in each case except for such matters as would not, individually or in
      the aggregate, have a Material Adverse Effect on the Packaging Business
      or the Packco Group.  As used herein, "Lien" shall mean, with respect to
      any asset, any mortgage, lien, pledge, charge, security interest,
      encumbrance or other adverse claim of any kind in respect of such asset.

            (h)  Litigation.  There are no civil, criminal or
      administrative actions, suits, claims, hearings or proceedings
      pending or, to the knowledge of its executive officers, threatened,
      or investigations pending, against Grace or its subsidiaries with
      respect to the Packaging Business, Packco or any Packco Subsidiary
      that, individually or in the aggregate, are reasonably likely to have
      a Material Adverse Effect with respect to the Packco Group or the
      Packaging Business.  There are no judgments or outstanding orders,
      writs, injunctions, decrees, stipulations or awards (whether rendered
      or issued by a court or Governmental Entity, or by arbitration)
      against Grace or its subsidiaries with respect to the Packaging
      Business, Packco or any Packco Subsidiary, or any of their respective
      properties or businesses, which are reasonably likely, individually
      or in the aggregate, to have a Material Adverse Effect with respect
      to the Packco Group or the Packaging Business.

            (i)  Taxes.  Except as reflected in Grace's SEC Documents filed
      with the SEC prior to the date hereof and except for such matters that,
      individually or in the aggregate, are not reasonably likely to have a
      Material Adverse Effect with respect to the Packco Group or the Packaging
      Business: (i) all federal, state, local and foreign tax returns required
      to be filed with respect to the Packaging Business, Packco or any Packco
      Subsidiary have been timely filed or requests for extensions have been
      timely filed and any such extension shall have been granted and not
      expired, and all such filed returns are complete and accurate in all

      Business Disclosure Letter Balance Sheet (in accordance with the Basis
      of Presentation set forth therein); (v) neither Grace, Packco nor any
      Packco Subsidiary is a party to any tax sharing or similar agreement

      Packaging Business), Packco nor any of the Packco Subsidiaries has
      waived any applicable statute of limitations with respect to any taxes.

            (j)  Environmental Matters.  Except as disclosed in the Grace SEC
      Documents filed prior to the date hereof and  except for such matters
      that, individually and in the aggregate, are not reasonably likely to
      have a Material Adverse Effect with respect to the Packco Group or the

      provided notice), or, to the knowledge of the executive officers of
      Grace, threatened by any Governmental Entity or any third party that
      assert that Grace or any of its subsidiaries, with respect to the
      Packaging Business, Packco, or any of the Packco Subsidiaries may be in
      violation of, or liable under, any Environmental Law (including as an

            (k)  Contracts and Commitments.  Except as set forth in the
      Packaging Business Disclosure Letter, and except for matters that would
      not, individually or in the aggregate, have a Material Adverse Effect
      with respect to the Packaging Business or the Packco Group, (i) Grace,
      Packco and the Packco Subsidiaries will not, as of the Effective Time,
      be parties to or bound by any Contract that materially limits the
      ability of Grace after the Merger, Packco,  the Surviving Corporation or
      any of their respective subsidiaries to compete in any line of business

      Disclosure Letter includes a complete list of all material employee
      benefit plans, programs, policies, practices and other arrangements
      (regardless of whether they are funded or unfunded or foreign or
      domestic, but excluding any such plans, programs, policies, practices
      and arrangements mandated or sponsored by a Governmental Entity with
      respect to foreign Packco Employees) providing benefits to any current
      or former Packco Employee or beneficiary or dependent thereof, sponsored

      meaning of Section 3(2) of ERISA; provided, that such list may not be
      complete as of the date hereof as to Packaging Business Plans providing
      benefits to foreign Packco Employees, but such list shall be updated so
      as to be complete as to such Packaging Business Plans promptly following
      the date hereof.  The Packaging Business Disclosure Letter also
      specifically identifies those Packaging Business Plans that are
      sponsored, maintained or contributed to exclusively by Packco or any of
      the Packco Subsidiaries exclusively for  the benefit of Packco Employees
      (the "Packaging Business-Only Plans").

          (ii)  With respect to each Packaging Business Plan providing
      benefits to U.S.  Packco Employees, Grace has delivered or made
      available to Sealed Air and, with respect to each Packaging Business
      Plan providing benefits to foreign Packco Employees, promptly
      following the date hereof, Grace will deliver or make available to
      Sealed Air, a true, correct and complete copy of each of the
      following:  (A) all plan documents and the current summary plan
      descriptions (if any);  (B) all benefit schedules, trust agreements
      and insurance contracts and other funding vehicles, if any;  (C) the
      most recent Annual Report (Form 5500 Series) and accompanying
      schedule, if any, or any similar filing made with any foreign
      authority;  (D) the most recent annual financial report, if any;  (E)
      the most recent actuarial report, if any; and (F) the most recent
      determination letter from the IRS or similar document issued by any
      other taxing authority, if any.  Except as specifically provided in
      the foregoing documents delivered or made available to Sealed Air,
      there are no amendments to any Packaging Business Plan that have been
      adopted or approved, nor has Grace or Packco undertaken to make any
      such amendments.

         (iii)  The Packaging Business Disclosure Letter identifies each
      Packaging Business Plan that is intended to be a "qualified plan"
      within the meaning of Section 401(a) of the Code (the "Packco
      Qualified Plans").  The IRS has issued a favorable determination
      letter with respect to each Packco Qualified Plan, in each case that
      has not been revoked, or an application for such a letter has been or
      will be filed before the expiration of the remedial amendment period,
      and Grace knows of no existing circumstances nor any events that have
      occurred that could adversely affect the qualified status of any such
      plan or the related trust.  No Packaging Business-Only Plan is
      intended to meet the requirements of Section 501(c)(9) of the Code.

          (iv)  Grace and its subsidiaries and Packco and the Packco
      Subsidiaries have complied, and are now in compliance, in all
      material respects, with all provisions of ERISA, the Code and all
      other laws and regulations applicable to the Packaging Business-Only
      Plans.  There is not now, nor do any circumstances exist that could
      give rise to, any requirement for the posting of security with
      respect to any Packaging Business-Only Plan or the imposition of any
      lien on the assets of Packco or a Packco Subsidiary under ERISA or
      the Code.  No prohibited transaction (as defined in ERISA) has
      occurred with respect to any Packaging Business-Only Plan.

           (v)  No Packaging Business-Only Plan is a "multi-employer plan"
      within the meaning of Section 4001(a)(3) of ERISA (a "Multiemployer
      Plan") or a plan that has two or more contributing sponsors at least
      two of whom are not under common control within the meaning of
      Section 4063 of ERISA (a "Multiple Employer Plan").  There does not
      now exist, nor do any circumstances exist that could result in, any
      liability under (A)  Title IV of ERISA, (B)  Section 302 of ERISA,
      (C)  Sections 412 and 4971 of the Code, (D) the continuation coverage
      requirements of Section 601 et seq. of ERISA and Section 4980B of the
      Code, or (E) corresponding or similar provisions of foreign laws or
      regulations, that would be a liability of Newco, Packco or a Packco
      Subsidiary following the Effective Time, other than such liabilities
      that arise solely out of, or relate solely to, the Packaging
      Business-Only Plans.

          (vi)  All contributions required to be made to any Packaging
      Business Plan by applicable law or regulation or by any plan document
      or other contractual undertaking, and all premiums due or payable
      with respect to insurance policies funding any Packaging Business
      Plan, have been timely made or paid in full.  Without limiting the
      generality of the foregoing, all contributions to the Hourly SIP and
      the Salaried SIP (each as defined in the Benefits Agreement) have
      been timely made in accordance with past practice.

         (vii)  All Packaging Business Plans covering foreign Packco
      Employees comply with applicable local law, except when the failure
      to so comply, individually or in the aggregate, would not have a
      Material Adverse Effect with respect to the Packco Group or the
      Packaging Business.

        (viii)  Neither the execution and delivery of this Agreement nor
      the consummation of the transactions contemplated hereby will (either
      alone or in conjunction with any other event) result in, cause the
      accelerated vesting or delivery of, or increase the amount or value
      of, any payment or benefit to any Packco Employee.  Without limiting
      the generality of the foregoing, no amount paid or payable in
      connection with the transactions contemplated hereby (either solely
      as a result thereof or as a result of such transactions in
      conjunction with any other event) will be an "excess parachute
      payment" within the meaning of Section 280G of the Code.

          (ix)  To the knowledge of the executive officers of Grace, Grace
      has, and, after the Effective Time, Packco will have, the right to
      amend or terminate any Packaging Business Plan to the extent it
      provides post-retirement medical and life insurance benefits under
      U.S.  Welfare Plans (as defined in the Benefits Agreement), other
      than such benefits that the New Grace Group is responsible for
      providing pursuant to the Benefits Agreement, and except as may be
      required by any applicable collective bargaining agreement.

            (m)  Trademarks, Patents and Copyrights.  Grace, Packco or a
      Packco Subsidiary owns or possesses adequate licenses or other rights to
      use all patents, trademarks, trade names, service marks, copyrights,
      licenses and product licenses or registrations (including applications
      for any of the foregoing), technology, know-how, tangible or intangible
      proprietary intellectual property rights, information or material
      (whether conceived, reduced to practice or under development), formulae,
      inventions and new and investigational applications (including all
      options or other rights to acquire any of the foregoing) as are
      necessary, used or held for use in connection with the Packaging
      Business (the "Packaging Business Intellectual Property"), the lack of
      which would reasonably be expected to have a Material Adverse Effect
      with respect to the Packco Group or the Packaging Business.  None of
      Grace, Packco or any of its subsidiaries has received any adverse claim
      by any other person with respect to the Packaging Business Intellectual
      Property or is aware, to the knowledge of the executive officers of
      Grace, Packco and the Packco Subsidiaries, of any infringements with
      respect thereto, and there is no infringement by Grace, Packco or any
      Packco Subsidiary of the intellectual property rights of others, which,
      in each case, would, individually or in the aggregate, reasonably be
      expected to have a Material Adverse Effect with respect to the Packco
      Group or the Packco Business.  Except for matters that would not,
      individually or in the aggregate, have a Material Adverse Effect with
      respect to the Packaging Business, immediately after the Contribution,
      Grace, Packco or a Packco Subsidiary will own or possess adequate
      licenses or other rights to use (subject to the terms of the
      Distribution Agreement, on substantially the same basis as currently
      owned or possessed by Grace and its Subsidiaries) all of the Packaging
      Business Intellectual Property.  Except as contemplated by  Section
      2.01(d) of the Distribution Agreement, there are no Contracts,
      agreements or licenses pursuant to which Grace or any subsidiaries of
      Grace which are not a member of the Packco Group will retain rights or
      interests of any kind in or affecting the Packaging Business
      Intellectual Property.

            5.3.  Representations and Warranties of Sealed Air.  Sealed Air
hereby represents and warrants to Grace that, except as set forth in a letter
delivered to Grace simultaneously with the execution and delivery of this
Agreement (the "Sealed Air Disclosure Letter"):

            (a)  Capital Stock.  The authorized capital stock of Sealed Air
      consists of 125,000,000 Sealed Air Common Shares, par value $.01 per
      share, of which 42,624,246 were outstanding as of August 14, 1997, and
      1,000,000 Sealed Air Preferred Shares, no par value, none of which was
      outstanding as of such date.  157,858 Sealed Air Common Shares were held
      in treasury by Sealed Air and its subsidiaries as of August 14, 1997.
      As of August 14, 1997, there were outstanding under the Sealed Air
      Amended Contingent Stock Plan and the Sealed Air Amended Restricted
      Stock Plan for Non-Employee Directors and any other plan for employees or
      directors of Sealed Air (collectively, the "Sealed Air Stock Plans") no
      awards granting rights to acquire Sealed Air Common Shares (subject to
      adjustment on the terms set forth in the Sealed Air Stock Plans).  As of
      August 14, 1997, there are no shares of capital stock of Sealed Air
      reserved for issuance, other than 547,050 Sealed Air Common Shares
      reserved for issuance pursuant to the Sealed Air Stock Plans.  All
      outstanding Sealed Air Common Shares have been duly authorized and
      validly issued and are fully paid and nonassessable.  Except for the
      Sealed Air Common Shares, Sealed Air has outstanding no bonds,
      debentures, notes or other obligations the holders of which have the
      right to vote (or are convertible or exchangeable into or exercisable
      for securities having the right to vote) with the shareholders of Sealed
      Air on any matter.  Each of the outstanding shares of capital stock of
      each of Sealed Air's subsidiaries has been duly authorized and validly
      issued and is fully paid and nonassessable and, except for an immaterial
      number of shares held by officers and directors of Sealed Air and its
      subsidiaries as required by applicable law, is owned, either directly or
      indirectly, by Sealed Air free and clear of all liens, pledges, security
      interests, claims, proxies, preemptive or subscriptive rights or other
      encumbrances or restrictions of any kind.  Except as set forth above and
      except for awards and Sealed Air Common Shares issued after August 14,
      1997 pursuant to the terms of the Sealed Air Profit Sharing Plan in
      accordance with Section 6.1(c), there are no shares of capital stock of
      Sealed Air authorized, issued or outstanding and there are no preemptive
      rights or any outstanding subscriptions, options, puts, calls, warrants,
      rights, convertible or exchangeable securities or other agreements or
      commitments of Sealed Air or any of its subsidiaries of any character
      relating to the issued or unissued capital stock or other securities of
      Sealed Air (including, without limitation, the issuance, sale, purchase,
      redemption, conversion, exchange, redemption, voting or transfer
      thereof).  As of the Effective Time, the number of Sealed Air Common
      Shares outstanding (including any awards pursuant to the Sealed Air
      Stock Plans) shall not exceed the number outstanding as of August 14,
      1997, except to the extent that such excess is reflected in an
      adjustment to the Per Share Common Consideration (as defined in the
      Distribution Agreement) as provided in the definition thereof.

            (b)  Corporate Organization and Qualification.  Each of Sealed Air
      and its subsidiaries is a corporation duly organized, validly existing
      and in good standing under the laws of its or such subsidiary's
      jurisdiction of organization and is in good standing (if recognized in
      such jurisdiction, or, if not, duly qualified) as a foreign corporation
      in each jurisdiction where the properties owned, leased or operated, or
      the business conducted, by it or such subsidiary require such
      qualification, except for any such failure so to qualify or be in good
      standing which, when taken together with all other such failures, is not
      reasonably likely to have a Material Adverse Effect with respect to
      Sealed Air.  Each of Sealed Air and its subsidiaries has the requisite
      corporate power and authority and all material governmental licenses and
      approvals to carry on its businesses as they are now being conducted.
      Sealed Air has made available to the other parties hereto a complete and
      correct copy of its Certificate of Incorporation and By-laws, each as
      amended to date and currently in full force and effect.

            (c)  Corporate Authority.  Subject only to the receipt of the
      requisite approval of its shareholders to consummate the Merger, Sealed
      Air has the requisite corporate power and authority and has taken all
      corporate action necessary in order to execute, deliver and perform each
      Transaction Agreement to which it is a party and to consummate the
      transactions contemplated hereby and thereby, including, without
      limitation, the approval of the  Sealed Air Board and the resolution of
      the Sealed Air Board to recommend, subject to their fiduciary duties,
      the transactions contemplated hereby and thereby for approval by Sealed
      Air shareholders.  Each Transaction Agreement to which Sealed Air is a
      party is, or when executed and delivered shall be, a valid and binding
      agreement of Sealed Air enforceable in accordance with its terms.  The
      affirmative vote of the holders of a majority of outstanding Sealed Air
      Common Shares in favor of the Merger is the only vote of the holders of
      Sealed Air's capital stock necessary in connection with the consummation
      of the Merger.

            (d)  Governmental Filings; No Violations.  (i)  Other than as may
      be required under the HSR Act and similar statutes in other countries,
      the Exchange Act, the Securities Act, and state securities laws, no
      notices, reports or other filings are required to be made by Sealed Air
      or any of its subsidiaries with, nor are any consents, registrations,
      approvals, permits or authorizations required to be obtained by it or
      any such subsidiary from, any Governmental Entity in connection with the
      execution, delivery or performance of each Transaction Agreement to
      which Sealed Air is a party and the consummation by Sealed Air of the
      transactions contemplated hereby and thereby, except for such matters as
      would not, individually or in the aggregate, have a Material Adverse
      Effect with respect to Sealed Air or prevent or materially delay or
      enable any person to enjoin consummation of the transactions
      contemplated hereby and thereby.

            (ii)  The execution, delivery and performance by Sealed Air of
      each Transaction Agreement to which it is a party does not or will not,
      and the consummation by it of any of the transactions contemplated
      hereby and thereby will not, constitute or result in (with or without the
      giving of notice, the lapse of time or both) (A) a breach or violation
      of, or a default under, its Certificate of Incorporation or By-laws, or
      (B) a breach or violation of, or a default under, or an acceleration or
      termination of or change in the rights or obligations of any party
      under, or the creation of a lien, pledge, security interest or other
      encumbrance on any assets pursuant to, any provision of any Contracts of
      it or any of its subsidiaries or any law, rule, ordinance or regulation
      or judgment, decree, order, award or governmental or non-governmental
      permit or license to which it or any of its subsidiaries is subject,
      except, in the case of clause (B) above, for such breaches, violations,
      defaults, accelerations or changes that are disclosed in the Sealed Air
      Disclosure Letter or,  individually and in the aggregate, are not
      reasonably likely to have a Material Adverse Effect with respect to
      Sealed Air or prevent or materially delay or enable any person to enjoin
      consummation of the Reorganization.

            (e)  SEC Documents; Financial Statements; No Undisclosed
      Liabilities.  (i)  Sealed Air has filed all forms, reports and documents
      required to be filed by it under the Exchange Act or the Securities Act
      since December 31, 1994.  As of its filing date, each such SEC Document
      filed, and each SEC Document that will be filed by Sealed Air or its
      subsidiaries prior to the Effective Time, as amended or supplemented, if
      applicable, pursuant to the Exchange Act or the Securities Act (A)
      complied or will comply in all material respects with the applicable
      requirements of the Exchange Act or the Securities Act and (B) did not
      or will not contain any untrue statement of a material fact or omit to
      state any material fact necessary in order to make the statements made
      therein, in the light of the circumstances under which they were made,
      not misleading.  Each of Sealed Air's consolidated balance sheets
      included in or incorporated by reference into its SEC Documents fairly
      presents in all material respects the consolidated financial position of
      it and its subsidiaries as of the dates set forth therein, and each of
      the consolidated statements of earnings, cash flows and shareholders'
      equity included in or incorporated by reference into its SEC Documents
      (including any related notes and schedules) fairly presents in all
      material respects the consolidated results of operations, cash flows and
      shareholders' equity, as the case may be, of Sealed Air and its
      subsidiaries for the periods set forth therein (subject, in the case of
      unaudited statements, to normal year-end audit adjustments), in each
      case in accordance with US GAAP (applied on a consistent basis).

          (ii)    Except as disclosed in its SEC Documents filed with the SEC
      prior to the date hereof, neither Sealed Air nor any of its subsidiaries
      has any liabilities of any kind whatsoever, whether or not accrued,
      contingent or otherwise, that, individually or in the aggregate, are
      reasonably likely to have a Material Adverse Effect with respect to
      Sealed Air.

            (f)  Absence of Certain Events and Changes.  Except as disclosed
      in its SEC Documents filed with the SEC prior to the date hereof, since
      December 31, 1996, Sealed Air and its subsidiaries have conducted their
      respective businesses only in the ordinary course of such businesses,
      and  there has not been any change or development or combination of
      changes or developments (including any worsening of any condition
      currently existing) which, individually or in the aggregate, is
      reasonably likely to result in a Material Adverse Effect with respect to
      Sealed Air.

            (g)  Compliance with Laws.  Except as disclosed in its SEC
      Documents filed with the SEC prior to the date hereof, Sealed Air and
      its subsidiaries have complied with all applicable federal, state, local
      and foreign statutes, laws, regulations, ordinances, rules, judgments,
      orders or decrees applicable thereto, except where the failure to comply
      is not reasonably likely, individually and in the aggregate, to have a
      Material Adverse Effect with respect to Sealed Air.  Sealed Air and its
      subsidiaries have, and, immediately after the Merger, will have, all
      permits, licenses, certificates of authority, orders, and approvals of,
      and has and will have made all filings, applications, and registrations
      with, federal, state, local, and foreign Governmental Entities that are
      required in order to permit it or such subsidiary to carry on its
      business as it is presently conducted, except for such permits, licenses,
      certificates, orders, filings, applications and registrations, the
      failure to have or make which, individually or in the aggregate, are not
      reasonably likely to have a Material Adverse Effect with respect to
      Sealed Air.

            (h)  Title to Assets.  Except as disclosed in its SEC Documents
      filed with the SEC prior to the date hereof, Sealed Air or its
      subsidiaries have and, immediately after the Merger, will:

                  (i)   have good and valid title to its properties and assets
            (including, without limitation, all assets reflected on the
            audited 1996 balance sheet of Sealed Air, except for such assets
            as were sold since December 31, 1996 in the ordinary course of
            business and not in violation of this Agreement), free and clear of
            any Liens; and

                  (ii)   own or have adequate rights to use all assets
            currently used or held for use by Sealed Air and its subsidiaries,
            and such rights are sufficient to permit Sealed Air to continue to
            operate Sealed Air's business as currently conducted by Sealed Air
            and its subsidiaries;

      in each case except for such matters as would not, individually or in
      the aggregate, have a Material Adverse Effect on Sealed Air.

            (i)  Litigation.  Except as disclosed in Sealed Air's SEC
      Documents filed with the SEC prior to the date hereof, there are no
      civil, criminal or administrative actions, suits, claims, hearings or
      proceedings pending or, to the knowledge of its executive officers,
      threatened, or investigations pending, against Sealed Air or any of its
      subsidiaries that, individually or in the aggregate, are reasonably
      likely to have a Material Adverse Effect with respect to Sealed Air.
      There are no judgments or outstanding orders, writs, injunctions,
      decrees, stipulations or awards (whether rendered or issued by a court
      or Governmental Entity, or by arbitration) against Sealed Air or any of
      its subsidiaries or their respective properties or businesses, which are
      reasonably likely, individually or in the aggregate, to have a Material
      Adverse Effect with respect to Sealed Air.

            (j)  Taxes.  Except as reflected in Sealed Air's SEC Documents
      filed with the SEC prior to the date hereof, and except for such matters
      that, individually or in the aggregate, are not reasonably likely to
      have a Material Adverse Effect with respect to Sealed Air, (i) all
      federal, state, local and foreign tax returns required to be filed by or
      on behalf of Sealed Air or any of its subsidiaries have been timely
      filed, or requests for extensions have been timely filed and have been
      granted and not expired, and all such filed returns are complete and
      accurate; (ii) all taxes shown as due and payable on returns filed by
      Sealed Air or any of its subsidiaries have been paid in full; (iii)
      there is no outstanding audit examination, deficiency, or refund
      litigation with respect to any taxes of Sealed Air or any of its
      subsidiaries; (iv) all taxes, interest, additions and penalties due with
      respect to completed and settled examinations or concluded litigation
      relating to Sealed Air or any of its subsidiaries have been paid in full
      or have been recorded as a liability on the balance sheet of Sealed Air
      (in accordance with US GAAP); (v) neither Sealed Air nor any of its
      subsidiaries is a party to a tax sharing or similar agreement or any
      agreement pursuant to which it or any of its subsidiaries has
      indemnified another party with respect to taxes; and (vi) neither Sealed
      Air nor any of its subsidiaries has waived any applicable statute of
      limitations with respect to any taxes.

            (k)  Contracts and Commitments.  Except as set forth in the Sealed
      Air Disclosure Letter, and except for matters that would not,
      individually or in the aggregate, have a Material Adverse Effect with
      respect to Sealed Air, (i) Sealed Air and its subsidiaries will not, as
      of the  Effective Time, be parties to or bound by any Contract that
      materially limits the ability of Grace after the Merger, Packco, the
      Surviving Corporation or any of their respective subsidiaries to compete
      in any line of business or with any person or in any geographic area;
      (ii) neither Sealed Air nor any of its subsidiaries is (with or without
      the lapse of time or the giving of notice, or both) in breach or default
      in any material respect under any Contract that is material to the
      operation of Sealed Air; (iii) none of the other parties to any Contract
      that is material to the operation of Sealed Air is (with or without the
      lapse of time or the giving of notice, or both) in breach or default in
      any material respect thereunder; and (iv) neither Sealed Air nor any of
      its subsidiaries has received any written notice of the intention of any
      party to terminate any such Contract whether as a termination for
      convenience or for default of Sealed Air or any of its subsidiaries
      thereunder.

            (l)  Employee Benefits.  (i)  The Sealed Air Disclosure Letter
      includes a complete list of all material employee benefit plans,
      programs, policies, practices and other arrangements (regardless of
      whether they are funded or unfunded or foreign or domestic, but
      excluding any such plans, programs, policies, practices and arrangements
      mandated or sponsored by a Governmental Entity with respect to foreign
      employees) providing benefits to any current or former employee of
      Sealed Air or any of its subsidiaries (collectively, "Sealed Air
      Employees") or beneficiary or dependent thereof, sponsored or maintained
      by Sealed Air or any of its subsidiaries, or to which Sealed Air or any
      of its subsidiaries contributes or is obligated to contribute (the
      "Sealed Air Plans"); provided, that such list may not be complete as of
      the date hereof as to Sealed Air Plans providing benefits to foreign
      Sealed Air Employees, but such list shall be updated so as to be
      complete as to such Sealed Air Plans promptly following the date hereof.
      Without limiting the generality of the foregoing, the term "Sealed Air
      Plans" includes all employee welfare benefit plans within the meaning of
      Section 3(1) of ERISA and all employee pension benefit plans within the
      meaning of Section 3(2) of ERISA.

          (ii)  With respect to each Sealed Air Plan providing benefits to
      U.S.  Sealed Air Employees, Sealed Air has delivered or made
      available to Grace, and with respect to each Sealed Air Plan
      providing benefits to foreign Sealed Air Employees, promptly
      following the date hereof, Sealed Air will deliver or make available
      to Grace, a true, correct and complete copy of each of the following:
      (A) all plan documents, (B) all benefit schedules, trust agreements
      and insurance contracts and other funding vehicles, and the current
      summary plan descriptions (if any);  (C) the most recent Annual
      Report (Form 5500 Series) and accompanying schedule, if any, or any
      similar filing made with any foreign authority;  (D) the most recent
      annual financial report, if any;  (E) the most recent actuarial
      report, if any; and (F) the most recent determination letter from the
      IRS or similar document issued by any other taxing authority, if any.
      Except as specifically provided in the foregoing documents delivered
      or made available to each of the parties hereto, there are no
      amendments to any Sealed Air Plan that have been adopted or approved,
      nor has Sealed Air undertaken to make any such amendments.

         (iii)  The Sealed Air Disclosure Letter identifies each Sealed Air
      Plan that is intended to be a "qualified plan" within the meaning of
      Section 401(a) of the Code ("Sealed Air Qualified Plans").  The IRS
      has issued a favorable determination letter with respect to each
      Sealed Air Qualified Plan, in each case that has not been revoked, or
      application for such a letter has been or will be filed before the
      expiration of the remedial amendment period, and Sealed Air knows of
      no existing circumstances nor any events that have occurred that
      could adversely affect the qualified status of any such plan or the
      related trust.  No Sealed Air Plan is intended to meet the
      requirements of Section 501(c)(9) of the Code.

          (iv)  Sealed Air and its subsidiaries have complied, and are now
      in compliance, in all material respects with all provisions of ERISA,
      the Code and all other laws and regulations applicable to the Sealed
      Air Plans.  There is not now, nor do any circumstances exist that
      could give rise to, any requirement for the posting of security with
      respect to any Sealed Air Plan or the imposition of any lien on the
      assets of Sealed Air under ERISA or the Code.  No prohibited
      transaction (as defined in ERISA) has occurred with respect to any
      Sealed Air Plan.

           (v)  All contributions required to be made to any Sealed Air
      Plan by applicable law or regulation or by any plan document or other
      contractual undertaking, and all premiums due or payable with respect
      to insurance policies funding any Sealed Air Plan, have been timely
      made or paid in full.

          (vi)  No Sealed Air Plan currently sponsored or maintained by
      Sealed Air, any of its subsidiaries or any of their respective ERISA
      Affiliates is subject to Title IV or Section 302 of ERISA or Section
      412 or 4971 of the Code.  Without limiting the generality of the
      foregoing, no Sealed Air Plan is a Multiemployer Plan or a Multiple
      Employer Plan, nor has Sealed Air or any ERISA Affiliate of Sealed
      Air, at any time since September 2, 1974, contributed to or been
      obligated to contribute to any Multiemployer Plan or Multiple
      Employer Plan.  There does not now exist, nor do any circumstances
      exist that could result in, any liability under (A)  Title IV of
      ERISA, (B)  Section 302 of ERISA, (C)  Sections 412 and 4971 of the
      Code, (D) the continuation coverage requirements of Section 601 et
      seq. of ERISA and Section 4980B of the Code, or (E) corresponding or
      similar provisions of foreign laws or regulations, that would be a
      liability of Sealed Air or any of its subsidiaries following the
      Effective Time, other than such liabilities that arise solely out of,
      or relate solely to, the Sealed Air Plans.

         (vii)  Neither Sealed Air nor any of its subsidiaries has any
      obligations for retiree health and life benefits under any Sealed Air
      Plan.

        (viii)  All Sealed Air Plans covering foreign Sealed Air Employees
      comply with applicable local law, except when the failure to so
      comply, individually or in the aggregate, would not have a Material
      Adverse Effect with respect to Sealed Air.

          (ix)  Neither the execution and delivery of this Agreement nor
      the consummation of the transactions contemplated hereby will (either
      alone or in conjunction with any other event) result in, cause the
      accelerated vesting or delivery of, or increase the amount or value
      of, any payment or benefit to any Sealed Air Employee.  Without
      limiting the generality of the foregoing, no amount paid or payable
      in connection with the transactions contemplated hereby (either
      solely as a result thereof or as a result of such transactions in
      conjunction with any other event) will be an "excess parachute
      payment" within the meaning of Section 280G of the Code.  Sealed Air
      and its subsidiaries have not entered into any change-of-control
      agreements under which Sealed Air will be obligated to make change-
      of-control payments following the Merger.

            (m)  Environmental Matters.  Except as disclosed in its SEC
      Documents filed prior to the date hereof and except for such matters
      that, individually and in the aggregate, are not reasonably likely to
      have a Material Adverse Effect with respect to Sealed Air, (i) Sealed
      Air and its subsidiaries are and have been in compliance with  all
      applicable Environmental Laws; (ii) Sealed Air and its subsidiaries hold
      and have held all permits under any Environmental Law required for the
      operation of their respective businesses as presently conducted and are
      in compliance with the terms of such permits; and (iii) neither Sealed
      Air nor any of its subsidiaries has received any outstanding written
      notices, demand letters, claims or requests for information, nor has any
      complaint been filed, penalty assessed, nor is any investigation,
      action, claim, suit, proceeding or review pending (with respect to which
      Sealed Air has been provided notice), or, to the knowledge of the
      executive officers of Sealed Air, threatened by any Governmental Entity
      or any third party that assert that Sealed Air or any of its
      subsidiaries may be in violation of, or liable under, any Environmental
      Law (including as an indemnitor in connection with any threatened or
      asserted claim by any third party indemnitee), and none of Sealed Air,
      its subsidiaries or its properties is subject to any citation, court
      order, administrative order or decree arising under any Environmental
      Law.  None of the real property owned or leased by Sealed Air or any of
      its subsidiaries is listed on, or, to the knowledge of Sealed Air's
      executive officers, proposed for listing on the "National Priorities
      List" under CERCLA, or any similar state, local or foreign list of sites
      requiring investigation or cleanup.


            (n)  Takeover Statutes; Rights Plans.  The execution, delivery and
      performance of this Agreement and consummation of the transactions
      contemplated hereby will not cause to be applicable to Sealed Air any
      Takeover Statute (after giving effect to any actions that will be taken
      prior to the Effective Time).  Sealed Air does not have any preferred
      share purchase rights plan or similar rights plan in effect.

            (o)  Brokers and Finders.  Neither Sealed Air nor any of its
      subsidiaries or any of their respective officers, directors or employees
      has employed any broker or finder or incurred any liability for any
      brokerage fees, commissions or finders' fees in connection with the
      transactions contemplated herein, except pursuant to arrangements
      disclosed in writing to the other parties hereto prior to the date
      hereof.

            (p)  Trademarks, Patents and Copyrights.  Sealed Air and its
      subsidiaries own or possess adequate licenses or other rights to use all
      patents, trademarks, trade names, service marks, copyrights, licenses
      and product licenses or registrations (including applications for any of
      the  foregoing), technology, know-how, tangible or intangible
      proprietary intellectual property rights, information or material
      (whether conceived, reduced to practice or under development), formulae,
      inventions and new and investigational applications (including all
      options or rights to acquire any of the foregoing) as are necessary,
      used or held for use in connection with its business (the "Sealed Air
      Intellectual Property"), the lack of which would reasonably be expected
      to have a Material Adverse Effect with respect to Sealed Air.  None of
      Sealed Air or any of its subsidiaries has received any adverse claim by
      any other person with respect to the Sealed Air Intellectual Property
      or is aware, to the knowledge of the executive officers of Sealed Air
      and its subsidiaries, of any infringement with respect thereto, and
      there is no infringement by Sealed Air or its subsidiaries of the
      intellectual property rights of others, which, in each case, would,
      individually or in the aggregate, reasonably be expected to have a
      Material Adverse Effect with respect to Sealed Air.  Except for matters
      that would not, individually or in the aggregate, have a Material
      Adverse Effect with respect to Sealed Air, immediately after the Merger,
      the Surviving Corporation and its subsidiaries will own or possess
      adequate licenses or other rights to use (on substantially the same
      basis as currently owned or possessed by Sealed Air and its
      subsidiaries) all of the Sealed Air Intellectual Property.

            (q)  Tax Matters.  At the Effective Time, the representations set
      forth in the Tax Matters Certificates of Sealed Air, substantially in
      the form of Exhibit B (the "Sealed Air Tax Matters Certificate"), will
      be true and correct in all respects, and such representations are hereby
      incorporated herein by reference with the same effect as if set forth
      herein in their entirety.

            (r)  Disclosure.  The representations and warranties of Sealed Air
      contained in this Agreement or in any written instrument, exhibit or
      certificate furnished or to be furnished by Sealed Air to Grace pursuant
      hereto or in connection herewith do not contain any untrue statement of
      a material fact or omit to state a material fact necessary in order to
      make the statements contained therein not misleading.


                                ARTICLE VI

                                 COVENANTS

            6.1.  Interim Operations.  Each of Grace and Sealed Air covenants
and agrees as to itself and its subsidiaries that, from and after the date
hereof until the Effective Time, except insofar as the other parties shall
otherwise consent or except as otherwise contemplated by this Agreement, the
Transaction Agreements or its Disclosure Letters (provided that, as used in
this Section, all references to Grace (and/or its Affiliates) shall be deemed
to refer to Grace and all of the Subsidiaries of Grace (in each case only with
respect to the Packaging Business), the Packco Group and the Packaging
Business except as otherwise specifically provided):

            (a)  The business of it and its subsidiaries will be conducted
      only in the ordinary and usual course and it and its subsidiaries will
      use all reasonable efforts to preserve their business organization
      intact and maintain their existing relations with customers, suppliers,
      employees and business associates.

            (b)  It will not (i) sell or pledge or agree to sell or pledge any
      stock owned, directly or indirectly, by it in any of its subsidiaries,
      (ii) amend its Certificate of Incorporation or By-laws (or similar
      organizational document); (iii) split, combine or reclassify any
      outstanding capital stock; or (iv) declare, set aside or pay any
      dividend payable in stock or property with respect to any of its capital
      stock (other than, in the case of Grace, regular quarterly cash
      dividends consistent with Grace's current practice, and intercompany
      dividends).

            (c)  Neither it nor any of its subsidiaries will issue, sell,
      pledge, dispose of or encumber, or authorize or propose the issuance,
      sale, pledge, disposition or encumbrance of, any shares of, or
      securities convertible or exchangeable for, or options, puts, warrants,
      calls, commitments or rights of any kind to acquire, any shares of its
      capital stock of any class other than common shares issuable pursuant to
      options, awards, warrants and other convertible securities outstanding
      on the date hereof and disclosed herein, provided that notwithstanding
      the foregoing (A) Grace may grant options to acquire Grace Common Shares
      so long as such options will not, after the Recapitalization, be or
      become options to purchase capital stock or other securities of Newco or
      any of its subsidiaries, and (B) in the ordinary course of business,
      Sealed Air may grant awards to acquire Sealed Air Common Shares or make
      all or part of its contribution to the Sealed Air Profit Sharing Plan in
      the form of Sealed Air Common Shares.

            (d)  Neither it nor any of its subsidiaries will (i) other than in
      the ordinary course of business, transfer, lease, license, guarantee,
      sell, mortgage, pledge or dispose of any property or assets or encumber
      any property or assets, or make any material acquisition of, or
      investment in, assets, stock or other securities of any other person or
      entity (other than its wholly-owned subsidiaries); or (ii) transfer,
      license, sell, pledge or dispose of any material Intellectual Property
      rights.

            (e)  Except as required or contemplated by agreements or
      arrangements disclosed in its SEC Documents or its Disclosure Letter,
      neither it nor any of its subsidiaries will grant any severance or
      termination pay to, or enter into, extend or amend any employment,
      consulting, severance or other compensation agreement with, any director
      or officer or, other than in the ordinary course of business consistent
      with past practice, other employees, except that the foregoing shall not
      prohibit Grace from entering into any such agreement or arrangement that
      will not be binding upon Newco or any of its subsidiaries after the
      Reorganization.

            (f)  Except as may be required to satisfy contractual obligations
      existing as of the date hereof (and disclosed in its Disclosure Letter)
      and the requirements of applicable law, and except in the ordinary and
      usual course of business, neither it nor any of its subsidiaries will
      establish, adopt, enter into, make, amend or make any elections under
      any collective bargaining, bonus, profit sharing, thrift, compensation,
      stock option, restricted stock, pension, retirement, employee stock
      ownership, deferred compensation, employment, termination, severance or
      other plan, agreement, trust, fund, policy or arrangement for the
      benefit of any directors, officers or employees that would be binding on
      Newco or any of its subsidiaries after the Reorganization.

            (g)  It will not implement any change in its accounting
      principles, practices or methods, other than as may be required by US
      GAAP, and other than as may be necessary or advisable in connection with
      the Reorganization.

            (h)  Neither Sealed Air nor Grace will adopt or propose any change
      in its certificate of incorporation or bylaws.

            (i)  Grace agrees to use its reasonable best efforts to cause each
      person that holds any shares of a Packco Subsidiary constituting
      directors qualifying shares to deliver at the Effective Time such shares
      at the direction of Sealed Air.

            (j)  Neither it nor any of its subsidiaries (including in the case
      of Grace, all members of the New Grace Group) shall intentionally take
      any action knowing that such action would cause a breach of a
      representation or warranty herein.

            (k)  It and its subsidiaries will conduct cash management
      operations (including the collection of accounts receivable and
      realization of cash from other assets and the payment of trade payables
      and other liabilities) only in the ordinary and usual course of
      business, consistent with past practices, and, except as contemplated by
      the Transaction Agreements, all transactions between the Packco Group or
      the Packaging Business, on the one hand, and the New Grace Group or the
      New Grace Business, on the other, shall only be in the ordinary and
      usual course of business, consistent with the past practices.

            (l)  Neither it nor any of its subsidiaries will authorize or
      enter into an agreement to take any of the actions referred to in
      paragraphs (a) through (k) above.

            6.2.  Certain Transactions.

            (a)  It is understood and agreed by the parties hereto that,
pursuant to the Distribution Agreement, at the time of the Reorganization and
subject to Section 2.02 of the Distribution Agreement, neither Grace nor any
member of the Packco Group shall have cash or marketable securities, it being
contemplated that, in connection with the Reorganization, such cash and
marketable securities shall be provided to Grace-Conn.

            (b)  Prior to the Distribution, Grace shall cause each of the
parties to the Distribution Agreement, the Tax Sharing Agreement and the
Benefits Agreement to duly enter into such agreements, which agreements shall
not be amended without the consent of Sealed Air, which will not be
unreasonably withheld.

            6.3.  Acquisition Proposals.  Each party hereto agrees that
neither it nor any of its subsidiaries nor any of its respective officers and
directors or the officers and directors of its subsidiaries shall, and it
shall each direct and use its best efforts to cause its employees, agents  and
representatives (including, without limitation, any investment banker, attorney
or accountant retained by it or any of its subsidiaries) not to, initiate,
solicit or encourage, directly or indirectly, any inquiries or the making or
implementation of any proposal or offer with respect to a merger, acquisition,
consolidation, business combination, recapitalization or similar transaction
involving, or any purchase of all or any significant portion of the assets or
any equity securities of, it or any of its subsidiaries (any such proposal or
offer being hereinafter referred to as an "Acquisition Proposal") or provide
any confidential information or data to, or have any discussions or engage in
any negotiations with, any person relating to an Acquisition Proposal;
provided, however, that the Grace Board or the Sealed Air Board may furnish or
cause to be furnished information (pursuant to confidentiality arrangements)
and may participate in such discussions and negotiations directly or through
its representatives if (i) the failure to provide such information or
participate in such negotiations and discussions would, in the opinion of its
outside counsel, cause the members of the Grace Board or the Sealed Air Board,
as the case may be, to breach their fiduciary duties under applicable law or
(ii) another person makes a written offer or written proposal that was not
solicited and did not otherwise result from a breach of this Section 6.3 and
which, based upon the identity of the person making such offer or proposal,
the terms thereof and the availability of adequate financing therefor, the
Grace Board or the Sealed Air Board, as the case may be, believes, in the good
faith exercise of its business judgment and based upon advice of its outside
legal and financial advisors, could reasonably be expected to be consummated
and represents a transaction more favorable to its shareholders than the
Reorganization (a "Higher Offer"); provided further, however, that the term
"Acquisition Proposal" shall not include a proposal exclusively involving all
or part of the stock or assets of New Grace and the New Grace Business so long
as any such proposal (and the consummation thereof) will not adversely affect
the transactions contemplated hereby.  Grace or Sealed Air, as the case may be,
shall notify the other party hereto as soon as practicable if any such
inquiries or proposals are received by, any such information is requested
from, or any such negotiations or discussions are sought to be initiated or
continued with it, which notice shall include the identity of the interested
person and the material terms and conditions of any inquiry, request for
information, offer or proposal.  Thereafter, the party giving the notice shall
keep the other reasonably informed of the status and details of any such
inquiry, request for information, offer or proposal, discussion or
negotiations.

            6.4.  Information Supplied.  Each of the parties hereto agrees
that none of the information supplied or to be supplied by it for inclusion or
incorporation by reference in any Registration Statement, the Joint Proxy
Statement or Schedule 14A, or any amendment or supplement thereto, will, in
the case of a Registration Statement, at the time such Registration Statement
and each amendment and supplement thereto becomes effective under the
Securities Act, or, in the case of a Joint Proxy Statement or Schedule 14A, at
the time such Joint Proxy Statement or Schedule 14A and each amendment and
supplement thereto is filed in definitive form with the SEC or mailed to
shareholders and at the time of the applicable Meeting, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein not
misleading.  All documents that either party is responsible for filing with
the SEC in connection with the Reorganization will comply as to form and
substance in all material respects with the applicable requirements of the
Exchange Act.

            6.5.  Shareholder Approvals.  Each of Grace and Sealed Air agrees
to take, in accordance with applicable law and its Certificate of
Incorporation and By-laws, all action necessary to convene a meeting of
holders of Grace Common Shares and Sealed Air Common Shares, respectively, as
promptly as practicable after the Registration Statements are declared
effective, and the Joint Proxy Statement is cleared, by the SEC, to consider
and vote upon the approval of the transactions contemplated by the Transaction
Agreements (including, without limitation, the Grace Amendment).  Subject to
the remainder of this Section 6.5, each of the Grace Board and the Sealed Air
Board shall recommend such adoption and approval and shall take all lawful
action to solicit such approval by shareholders.  The Grace Board or the
Sealed Air Board, as the case may be, may fail to make such a recommendation,
or withdraw, modify, or change any such recommendation, or recommend another
offer or proposal, if (i) the making of such recommendation or failing to
withdraw, modify or change its recommendation or to recommend another offer or
proposal would, in the opinion of its outside counsel, cause the members of
the Grace Board or the Sealed Air Board, as the case may be, to breach their
fiduciary duties under applicable law, or (ii) there is a Higher Offer.  In
such event, notwithstanding anything contained in this Agreement to the
contrary, any such failure to recommend, withdrawal, modification or change of
recommendation or recommendation of such other offer or proposal, or the
entering by Grace or Sealed Air into an agreement with respect to a Higher
Offer (provided that Grace or Sealed Air, as the case may be, shall have
provided the other party with at least four days' prior notice of its
intention to enter into such agreement and the  identity of the other party
thereto and the material terms and conditions of the agreement to be entered
into with such person), shall not constitute a breach of this Agreement by
Grace or Sealed Air, as the case may be.

            6.6.  Filings; Other Actions.  (a)  Subject to the obligations of
consultation contained herein, Grace and Sealed Air shall promptly prepare for
filing the Grace Registration Statement and the Joint Proxy Statement to be
mailed to their shareholders, and Grace shall prepare the New Grace
Registration Statement (and related prospectus forming a part thereof to be
mailed to the Grace shareholders), in each case in connection with the
Reorganization.  In connection with the foregoing, Grace shall prepare audited
annual and unaudited interim financial statements prepared in accordance with
US GAAP and in compliance with Regulation S-K under the Securities Act for the
Packaging Business (including Grace after giving effect to the Distribution)
and for the New Grace Business, and such financial statements shall be
included in the Registration Statements and the Joint Proxy Statement as may
be appropriate.  Each party hereto shall use its reasonable efforts, after
consultation with the other parties hereto, to respond promptly to any comments
made by the SEC with respect to such filings, to have such filings declared
effective or cleared, as the case may be, and cause such filings to be mailed
at the earliest reasonably practicable time.  Each party hereto and its
counsel shall be given a reasonable opportunity to review and comment on each
version of such filings prior to the filing thereof with the SEC.  Each party
hereto also shall use its reasonable efforts to obtain all necessary state
securities law or blue sky permits and approvals required to carry out the
transactions contemplated hereby and shall furnish all information as may be
reasonably requested in connection with any such action.

            (b)  Each party hereto shall cooperate with the other parties
hereto, subject to the terms and conditions set forth herein, use its
reasonable efforts promptly to prepare and file all necessary documentation,
to effect all necessary applications, notices, petitions, filings and other
documents, and to obtain as promptly as reasonably practicable all necessary
permits, consents, orders, approvals and authorizations of, or any exemption
by, all third parties and Governmental Entities necessary or advisable to
consummate the transactions contemplated hereby.  Each party hereto shall
consult with the other parties hereto with respect to the obtaining of all
permits, consents, approvals and authorizations of all third parties and
Governmental Entities necessary or advisable to consummate the transactions
contemplated hereby, and each party shall keep the other parties hereto
apprised of the status of matters relating to completion of the transactions
contemplated hereby.

            (c)  Each party hereto shall, upon reasonable request and except
as otherwise may be required by applicable law, furnish the other parties
hereto with all information concerning itself, its subsidiaries, directors,
officers, shareholders and other Affiliates and such other matters as may be
reasonably necessary or advisable in connection any statement, filing, notice
or application made by or on behalf of such other party or any of its
Affiliates to any Governmental Entity in connection with any transactions
contemplated by this Agreement.

            (d)  Each party hereto shall, subject to applicable laws
relating to the disclosure and exchange of information, promptly furnish
the other parties hereto with copies of written communications received by
each such party or any of its subsidiaries, from, or delivered by any of
the foregoing to, any Governmental Entity in respect of the transactions
contemplated hereby.

            (e)  Each party hereto shall cooperate with each other party
hereto and shall use reasonable efforts to take or cause to be taken all
actions and do or cause to be done all things reasonably necessary, proper or
advisable to obtain favorable review of the proposed transaction under the HSR
Act and any foreign antitrust or competition laws.

            6.7.  Audited Financial Statements; Comfort Letters.  (a)  Grace
shall prepare, as promptly as practicable, audited annual and unaudited
interim financial statements with respect to each of the New Grace Group and
the Packco Group, as described in Section 6.6(a) hereto.  Grace shall deliver
to Sealed Air copies of any such financial statements relating to the
Packaging Business, which shall be certified without qualification by Price
Waterhouse LLP or other nationally recognized accounting firm reasonably
acceptable to Sealed Air (the "Packaging Business Financial Statements").

            (b)  Each of Grace and Sealed Air shall use all reasonable efforts
to cause to be delivered to the other party, as appropriate, and its directors
letters of its independent accountants, dated (i) the date on which each
Registration Statement shall become effective and (ii) a date shortly prior to
the Effective Time, and addressed to such other party and its directors, in
form and substance customary for "comfort" letters delivered by independent
accountants in connection with registration statements.

            6.8.  Access.  Upon reasonable notice, and except as may otherwise
be required by applicable law, each party hereto shall afford each other
party's Representatives  access, during normal business hours throughout the
period until the Effective Time, to its properties, books, Contracts and
records and, during such period, shall (and shall cause each of its
subsidiaries to) furnish promptly to the other party all information
concerning its business, properties and personnel as may reasonably be
requested; provided that no investigation pursuant to this Section 6.8 shall
affect or be deemed to modify any representation or warranty made by the party
furnishing such information; provided further that with respect to the work
papers of independent accountants or any other contract, document, information
or other material the provision of which is not permitted without the consent
of a third party, the provision of access shall be subject to the permission
of such independent accountants or such third party, and each party hereto
shall use reasonable efforts to secure such permission for the other.  Each
party hereto shall not, and shall cause its respective Representatives not to,
use any information obtained pursuant to this Section 6.8 for any purpose
unrelated to the consummation of the transactions contemplated by the
Transaction Agreements.  All information obtained pursuant to this paragraph
shall be subject to the provisions of the written confidentiality arrangements
existing among the parties hereto.

prompt notice to the other party of (i) any material inaccuracy in any
representation or warranty made by it in this Agreement, (ii) any material
failure by it to comply with any of its covenants or agreements under this
Agreement and (iii) any change or event that is reasonably likely to result in
any Material Adverse Effect or to delay, in any substantial respect, or
prevent consummation of the Reorganization, in each case to the knowledge of
the executive officers.

            6.10.  Publicity.  The initial press release relating hereto shall
be a joint press release and, thereafter, each party hereto shall consult with
each other party hereto prior to issuing any press releases or otherwise
making public statements with respect to the transactions contemplated hereby
and prior to making any filings with any Governmental Entity or stock exchange
with respect thereto; provided that, if a party shall be advised by counsel
that any such press release, statement or filing is required by applicable law
and it shall not be practicable to consult with the other parties prior to the
time such press release, statement or filing is required, a party may make
such press release, statement or filing and shall promptly notify the other
parties thereof.

            6.11.  Employee Benefits; Headquarters Employees.  (a)  Grace and
Sealed Air covenant and agree that  from and after the Effective Time, Grace,
Packco and the Surviving Corporation, as the case may be, shall maintain
either employee benefits plans and programs that are, in the aggregate, at
least substantially comparable to the plans and programs in effect with
respect to Packco Employees at the Effective Time or other plans that are, in
the aggregate, at least substantially comparable to the plans and programs in
effect from time to time with respect to comparable Sealed Air employees.

            (b)  As a result of the Merger, Sealed Air acknowledges that it
will need to add employees to its corporate staff and related support
services, including in the areas of legal, tax, human resources, accounting,
risk management, cash management, investor relations, information systems and
internal audit.  In seeking to fill these needs, Sealed Air shall work with
Grace to identify, prior to the Effective Time, appropriate people located at
Grace's Boca Raton headquarters and shall give such individuals preferential
consideration.

            6.12.  Expenses.  (a)  Except as set forth in paragraphs (b) and
(c) below, Section 8.04 of the Distribution Agreement and in the Other
Agreements, all costs and expenses, including without limitation, legal,
investment banking, financial, accounting and other professional fees and
expenses, incurred by Grace or its subsidiaries in connection with the
Transaction Agreements and the transactions contemplated thereby shall be paid
by New Grace (or if the Reorganization is not consummated, Grace) and all such
costs and expenses incurred by Sealed Air or its subsidiaries shall be paid by
Newco (or if the Reorganization is not consummated, Sealed Air); provided,
however, that the costs and expenses of printing and mailing the Joint Proxy
Statement and the Grace Registration Statement, and all filing fees paid to
the SEC in connection therewith, shall be evenly divided between New Grace (or
if the Reorganization is not consummated, Grace) and Sealed Air.  The payments
under this Section 6.12 shall not be in limitation of the rights of the
parties hereto under Sections 8.5 and 9.10 hereof.

            (b)  In the event that:

            (i)  this Agreement shall be terminated pursuant to:

                  (A)  Section 8.2(iii) (due to a Higher Offer with respect to
            Grace);

            Grace shareholders do not  approve the matters required by Section
            7.1(a) and, within one year after termination of this Agreement,
            Grace consummates or enters into a written agreement to consummate
            an Acquisition Proposal (except that, for this purpose, the
            reference to "significant portion" in the definition thereof in
            Section 6.3 shall mean 20%) or any person (other than an employee
            stock or similar plan for the benefit of Grace employees) or group
            of affiliated persons shall acquire beneficial ownership (as
            defined in Rule 13d-3 under the Exchange Act) of at least 35% of
            the outstanding Grace Common Shares;

            definition thereof in Section 6.3 shall mean 20%) or any person
            (other than an employee stock or similar plan for the benefit of
            Grace employees) or group of affiliated persons shall acquire
            beneficial ownership (as defined in Rule 13d-3 under the Exchange
            Act) of at least 35% of the outstanding Grace Common Shares; or

            shareholder approval at the Grace Meeting other than in the
            circumstances described in clause (B)); and

            (ii)  at the time of such termination, Sealed Air shall not be in
      material breach of its covenants or agreements contained in this
      Agreement;

then, Grace shall pay to Sealed Air, in exchange for a complete release of any
liabilities of Grace hereunder, the amount of (1) $150 million plus actual out

                  (A)  Section 8.2(iii) (due to a Higher Offer with respect to
            Sealed Air);

                  (B)  Section 8.2(ii), if, after an Acquisition Proposal with
            respect to Sealed Air has been publicly disclosed or announced,
            the Sealed Air shareholders do not approve the matters required by
            Section 7.1(a), and, within one year after termination of this
            Agreement, Sealed Air consummates or enters into a written

            definition thereof in Section 6.3 shall mean 20%) or any person
            (other than an employee stock or similar plan for the benefit of
            Sealed Air employees) or group of affiliated persons shall acquire

            Act) of at least 35% of the outstanding Sealed Air Common Shares;
            or

                  (D)  Section 8.2(ii) (due to a failure to obtain Sealed Air
            shareholder approval at the Sealed Air Meeting other than in the
            circumstances described in clause (B)); and

            (ii)  at the time of such termination, Grace shall not be in
      material breach of its covenants or agreements contained in this
      Agreement;

contemplated hereby and otherwise act to eliminate or minimize the effects of
any Takeover Statute on any of the transactions contemplated by this Agreement.

            6.14.  Securities Act Compliance.  As soon as practicable after
the date of the Meetings, each party hereto shall identify all persons who
were, at the time of the Meetings, possible Affiliates, shall use its
reasonable efforts to obtain a written agreement in the usual and customary
form from each person who is so identified as a possible Affiliate and shall
deliver such written agreements to Grace or Newco as soon as practicable after
the Meetings.

            6.15.  Transaction Agreements.  (a)  Prior to the Effective Time,
the parties shall consummate any transactions to be consummated prior to the
Effective Time pursuant to the Distribution Agreement or the Other Agreements.

Distribution Agreement or the Other Agreements without the consent of the
other parties hereto, which consent shall not be unreasonably withheld.

            6.16.  Tax Matters.  Each party agrees to report the Distribution
as a tax-free distribution under the Code and the Merger as a tax-free
reorganization under the Code on all tax returns and other filings, and take
no position inconsistent therewith, except where, in the opinion of nationally
recognized tax counsel to such party, there is not "substantial authority,"
as defined in Section 6662 of the Code, to support such a position.

                                CONDITIONS

obligation of each party hereto to consummate the Reorganization is subject to
the fulfillment of each of the following conditions:

            (a)  Shareholder Approval.  To the extent required by law or stock
      exchange regulations, the transactions contemplated by the Transaction
      Agreements shall have been duly approved by the shareholders of Sealed
      Air and Grace in accordance with applicable law.

            (b)  Governmental and Regulatory Consents.  The waiting periods
      applicable to the consummation of the Merger under the HSR Act shall
      have expired or been terminated; and all filings required to be made
      prior to the Closing by any party hereto or any of its respective
      subsidiaries with, and all consents, approvals and authorizations
      required to be obtained prior to the Closing by any party hereto or any
      of its respective subsidiaries from, any Governmental Entity in
      connection with the execution, delivery and performance of this
      Agreement, the Distribution Agreement and the Other Agreements and the
      consummation of the transactions contemplated hereby and thereby (to the
      extent such transactions are required to be consummated prior to the
      Effective Time) shall have been made or obtained, except where the
      failure to obtain such consents, approvals and authorizations (i) is not
      reasonably likely to have a Material Adverse Effect on (A) the New Grace
      Group (with respect to the condition for Grace) or (B) the Packco Group
      or Sealed Air (with respect to the condition for Sealed Air), and (ii)
      could not reasonably be expected to subject the parties hereto or their
      Affiliates or any directors or officers of any of the foregoing to
      criminal liability.

            (c)  Third-Party Consents.  All consents or approvals of all

      Distribution Agreement and the Other Agreements and the consummation of
      the transactions contemplated hereby and thereby shall have been
      obtained and shall be in full force and effect, except for those the
      failure of which to obtain would not have a Material Adverse Effect with
      respect to (i) the New Grace Group (with respect to the condition for
      Grace), or (ii)  the Packco Group or Sealed Air (with respect to the
      condition for Sealed Air).

            (d)  Governmental Matters.  No Governmental Entity of competent
      jurisdiction shall have enacted, issued, promulgated, enforced or
      entered any statute, rule, regulation, judgment, decree, injunction or

      Wachtell, Lipton, Rosen & Katz, dated the date of the Effective Time,

      Registration Statements shall have been issued and no proceedings for
      that purpose shall have been initiated or threatened by the SEC.

            (g)  The Contribution, the Distribution and the Recapitalization.

      been consummated as provided in the Distribution Agreement, and the
      conditions to consummation of such transactions set forth in Section 8.01
      of the Distribution Agreement shall have been satisfied or, to the
      reasonable satisfaction of Sealed Air, shall have been waived.

            (h)  Stock Exchange Listing.  The Newco Common Shares and Newco
      Convertible Preferred Shares to be issued in the Recapitalization and
      the Merger shall have been authorized  for listing on the NYSE, subject

      material respects as of such date) disregarding with respect to the
      Closing Date all qualifications and exceptions contained therein
      relating to materiality or Material Adverse Effect, except for such
      matters as would not in the aggregate reasonably be expected to have a
      Material Adverse Effect with respect to Sealed Air, and Grace shall have
      received a certificate signed on behalf of Sealed Air by an officer to
      such effect.

            (b)  Performance of Obligations.  Sealed Air shall have performed
      in all material respects all obligations required to be performed by it

      date), disregarding all qualifications and exceptions contained therein
      relating to materiality or Material Adverse Effect, except for such

      behalf of Grace by an officer to such effect.

            (b)  Performance of Obligations.  Grace shall have performed in

unenforceable, shall remain in full force and effect  and shall in no way be

                          DISTRIBUTION AGREEMENT


            This DISTRIBUTION AGREEMENT (this "Agreement"), dated as of [
   ], 1997, by and among W. R. Grace & Co., a Delaware corporation ("Grace"),
W. R. Grace & Co.-Conn., a Connecticut corporation and a wholly owned
subsidiary of Grace ("Grace-Conn.") and Grace Specialty Chemicals, Inc., a
Delaware corporation and a wholly owned subsidiary of Grace ("New Grace").


                                 RECITALS
                                 --------

            A.  The Merger Agreement.  Grace and Sealed Air Corporation, a
Delaware corporation ("SAC"), have entered into an Agreement and Plan of
Merger, dated as of August 14, 1997 (the "Merger Agreement"), pursuant to
which, at the Effective Time (as defined therein), a wholly owned subsidiary
of Grace will merge with and into SAC, with SAC being the surviving
corporation (the "Merger"), and Grace being renamed "Sealed Air Corporation".

            B.  The Distribution Agreement.  This Agreement and the Other
Agreements (as defined herein) set forth certain transactions that SAC has
required as a condition to its willingness to consummate the Merger, and the
purpose of this Agreement is to make possible the Merger by divesting Grace of
the businesses and operations to be conducted by New Grace and its
subsidiaries, including Grace-Conn.

            C.  The Contribution.  Prior to the Effective Time, and subject to
the terms and conditions set forth in this Agreement, Grace intends to cause
the transfer to a wholly owned subsidiary of Grace-Conn. ("Packco") of certain
assets and liabilities of Grace and its subsidiaries predominantly related to
the Packaging Business (the "Contribution"), as contemplated by this Agreement
and the Other Agreements.

            D.  Financing.  It is the intention of the parties hereto that,
prior to the Distribution:  (i) Grace and/or Packco shall enter into new
financing arrangements and shall make, or cause to be made, the New Grace
Capital Contribution (as defined herein); and (ii) the parties shall cooperate
with one another with respect to the foregoing.

            E.  The Distribution.  Following the Contribution and prior to the
Effective Time, subject to the conditions set forth in this Agreement, (i) the
capital stock of Packco will  be distributed to Grace (the "Intragroup
Spinoff"), (ii) the capital stock of Grace-Conn. will be contributed to New
Grace and (iii) all of the issued and outstanding shares of the common stock
of New Grace (together with the New Grace Rights, "New Grace Common Stock")
will be distributed on a pro rata basis (the "Distribution") to the holders as
of the Record Date of the common stock of Grace, par value $.01 per share
("Grace Common Stock"), other than shares held in the treasury of Grace.

            F.  The Recapitalization.  Following the Distribution and
immediately prior to the Effective Time, Grace intends to consummate the
Recapitalization in which each holder of a share of Grace Common Stock shall
hold, immediately thereafter, the Per Share Common Consideration and the Per
Share Preferred Consideration.

            G.  Intention of the Parties.  It is the intention of the parties
(i) to this Agreement that, for United States federal income tax purposes, the
Contribution and associated transactions shall qualify as a tax-free
transaction under Section 351 of the Internal Revenue Code of 1986, as amended
(the "Code"), the Contribution and the Intragroup Spinoff (and associated
transactions) shall qualify as a tax-free transaction under Sections 355 and
368 of the Code, the Distribution and associated transactions shall qualify as
a tax-free transaction under Sections 355 and 368 of the Code, and the
Recapitalization shall be tax-free to Grace and its shareholders under the
Code, and (ii) to this Agreement and the Merger Agreement that the Merger
shall qualify as a "reorganization" within the meaning of Section 368 of the
Code and the Merger will be tax free under the Code to Grace, SAC and their
respective shareholders.

            NOW, THEREFORE, in consideration of the premises, and of the
representations, warranties, covenants and agreements set forth herein, the
parties hereto hereby agree as follows:

Benefit Plan Liabilities and the Foreign Benefit Plan Liabilities (each as
defined below).

            "U.S. Plan Assets" means the aggregate fair market value, as of
      the Distribution Date, of the assets of the Union Retirement Plan (as
      defined in the Benefits Agreement) and the assets that will be
      transferred to the Packco Hourly Non-Union Retirement Plan (as defined in
      the Benefits Agreement) pursuant to Section 4.01(d) of the Benefits
      Agreement, in each case as reasonably determined by Actuarial Sciences
      Associates ("ASA").  "Foreign Plan Assets" means the aggregate fair
      market value, as of the Distribution Date, of the assets that will be,
      pursuant to the Foreign Plans Agreement (as defined in the Benefits
      Agreement), transferred from a Noninsured Foreign Pension Plan (as
      defined in the Benefits Agreement) that is a New Grace Benefit Plan (as
      defined in the Benefits Agreement) (a "Transferring New Grace Foreign
      Plan") to a Packco Benefit Plan or retained by a Noninsured Foreign
      Pension Plan that is a Packco Benefit Plan (a "Retained Grace Foreign
      Plan"), in each case as reasonably determined by the Local Actuary (as
      defined in the Benefits Agreement) for the relevant Transferring New
      Grace Foreign Plan or Retained Grace Foreign Plan.

                  "U.S. Benefit Plan Liabilities" means the sum of the Accrued
      Benefit Obligation, calculated in accordance with FAS 87 ("ABO"), for
      (i) benefits of Packco Participants (as defined in the Benefits
      Agreement) under the Union Retirement Plan and (ii) benefits of Packco
      Participants under the Hourly Non-Union Retirement Plan (as defined in
      the Benefits Agreement) that are assumed by the Packco Hourly Non-Union
      Retirement Plan pursuant to Section 4.01(d) of the Benefits Agreement.
      "Foreign Benefit Plan Liabilities" means the greater of (i) the sum of
      the  ABOs for the Assumed Foreign Benefits (as defined below) plus $10
      million and (ii) the sum of the Projected Benefit Obligations,
      calculated in accordance with FAS 87 ("PBO"), for the Assumed Foreign
      Benefits.  The "Assumed Foreign Benefits" means the aggregate amount of
      the retirement benefits of Packco Participants under each Noninsured
      Foreign Pension Plan that are, pursuant to the Foreign Benefits
      Agreement, either assumed by a Packco Benefit Plan from a Transferring
      New Grace Foreign Plan or retained by a Retained Grace Foreign Plan.

            The determination of U.S. Benefit Plan Liabilities shall be made
by ASA in accordance with the actuarial and other assumptions set forth on
Schedule 1.01(f).  The determination of the ABOs and PBOs for the Assumed
Foreign Benefits shall in each case be made by AON Consulting ("AON") as of
the Distribution Date based upon the actuarial and other assumptions used by
AON to determine the ABO or PBO (as applicable) of the relevant Transferring
New Grace Foreign Plan or Retained Grace Foreign Plan for purposes of Grace's
fiscal 1996 year-end financial disclosures, if such ABO or PBO is reported
thereon, which actuarial and other assumptions are set forth on Schedule
1.01(f), provided, in the case of the assumptions relating to each Noninsured
Foreign Pension Plan, that such assumptions are reasonable.  To the extent
that the ABO or PBO for a particular Transferring New Grace Foreign Plan or
Retained Grace Foreign Plan was not so reported, such assumptions shall be
reasonable assumptions developed by AON in the manner most typically used by
AON to develop assumptions for determining ABO or PBO for FAS 87 purposes for
substantially similar plans in the applicable jurisdiction.

            ASA, the Local Actuaries and AON (collectively, the "Actuaries")
shall initially make the determinations called for by this definition on a
good-faith estimated basis not later than December 31, 1997 or such other date
as the parties hereto shall request.  In making such initial determinations,
the local Actuaries shall be entitled to rely upon the advice of Grace and New
Grace with respect to the anticipated terms and conditions of the Foreign
Plans Agreement (if it has not yet been signed) and the manner in which its
terms and conditions will be implemented.  Final determinations shall be made
by the Actuaries as and when the asset transfers and assumptions of
liabilities contemplated by the Foreign Plans Agreement and Section 4.01(d) of
the Benefits Agreement are completed, and the New Grace Capital Contribution
shall be adjusted as necessary to reflect the Net Benefit Amount as so finally
determined.  Grace and New Grace agree to cooperate in supplying the Actuaries
with all information reasonably requested by them in connection with making
such determinations, including, without  limitation, information concerning
Plan participants, assets and benefits.  Grace, New Grace and SAC shall be
entitled to review and comment on the Actuaries' analyses as the Actuaries are
in the process of making their determinations.

            New Grace:  as defined in the preamble to this Agreement.

    plus    (b)   the aggregate amount of cash held by Packco or any Packco
                  Subsidiaries immediately prior to the Distribution;

                              on a deemed distribution to Packco by each
                              Foreign Packco Subsidiary immediately following
                              the Distribution, of an amount of cash equal to
                              the excess of (I) the amount of cash held by such
                              Foreign Packco Subsidiary immediately prior to
                              the Distribution over (II) the sum of (A) the
                              amount of debt that may be repaid without penalty
                              plus current accrued but unpaid Taxes of such
                              Subsidiary as of the Distribution Date and (B)
                              Excess Short-Term Payables of such Subsidiary;
                              provided, however, that such amount of cash
                              shall be determined taking into account the
                              principles, as applied to Packco, set forth in
                              the proviso in Section 2.02(c)(v), and (y) Taxes
                              that would be imposed by the United States or

            Activities") by Grace, Grace-Conn. or any of their respective

            Date.

share) of Newco Common Stock issuable in the Recapitalization per share of
Grace Common Stock outstanding as of the Record Date, such amount to be
determined by dividing (a) the amount equal to (I) 40,895,000, increased by
the product, if any, of (x) 1.7027 and (y) the net increase in outstanding

minus (II) the Net Option Number, by (b) the aggregate number of shares of
Grace Common Stock outstanding as of the Record Date, the result being rounded

rounded up to the next one-thousandth).  "Net Option Number" means

                  (i)   the aggregate number of shares of Newco Common Stock
                        into which all outstanding options to purchase shares
                        of Grace Common Stock outstanding as of the
                        Distribution Date and held by Packco Employees are or
                        may be exercisable (whether or not then exercisable)

                        calculated as provided in the Benefits Agreement, the
                        "Newco Options"), multiplied by the amount by which:

                              highest and lowest sales prices of a share of
                              Newco Common Stock on the New York Stock Exchange
                              Composite Tape on each of the five trading days

                              Distribution (the "SAC Stock Price")

               exceeds (II)   the weighted average per-share exercise price
                              for the Newco Options, calculated as provided in
                              the Benefits Agreement;

           divided by   (ii)  the SAC Stock Price.

Fractional shares otherwise issuable to a Grace shareholder shall be treated
as provided in Section 2.07(b).  In the event that shares of Grace Common
Stock are issued between the Record Date and the Effective Time, including

issuances in the Recapitalization), such Consideration shall be appropriately
adjusted.

            Per Share Preferred Consideration:  the shares (or fraction of a
share) of Newco Convertible Preferred Stock issuable in the Recapitalization
per share of Grace Common Stock outstanding as of the Record Date, such amount

Grace Common Stock outstanding as of the Record Date, the result being rounded
to the nearest one-thousandth (or, in the event there is no nearest number,
rounded up to the next one-thousandth).  Fractional shares otherwise issuable
to a Grace shareholder shall be treated as provided in Section 2.07(b).  In
the event that shares of Grace Common Stock are issued between the Record Date
and the Effective Time, including pursuant to the exercise of stock options
granted by Grace (but not including issuances in the Recapitalization), such
Consideration shall be appropriately adjusted.

                                ARTICLE II

            CERTAIN TRANSACTIONS PRIOR TO THE DISTRIBUTION DATE

            SECTION 2.01  Transfer of Packco Assets; Assumption of Packco
Liabilities.  (a)  Prior to the Distribution Date but subject to Section 2.02,
Grace shall transfer, or cause to be transferred to Packco or, at Packco's
option, to a Packco Subsidiary effective as of the Distribution Date all of the
Packco Assets.  Immediately prior to the Distribution, the capital stock of
Packco shall be distributed to Grace.  Grace shall also transfer, or cause to
be transferred, the capital stock of any Subsidiary such that, as of the
Distribution Date, the Packco Subsidiaries shall be wholly owned (except for
shares held by directors or officers to comply with applicable law) by a
member of the Packco Group and the New Grace Subsidiaries shall be wholly
owned (except for shares held by directors or officers to comply with
applicable law) by a member of the New Grace Group.  Effective as of the
Distribution Date, the transfers described in this Section will result in
Packco or another member of the Packco Group obtaining all of the rights,
title and interests of Grace and its Subsidiaries in the Packco Assets,
subject to Sections 2.05 and 2.10.

            (b)  Effective as of the Distribution Date and subject to Section
2.02, Packco shall, or shall cause a Packco Subsidiary to, assume, pay,
perform, and discharge in due course all of the Packco Liabilities.

            (c)   Separation of Assets.  The Packco Assets and Grace-Conn.
Assets (including Assets that are, or are contained in, the Shared Facilities)
shall, to the extent reasonably practicable (including taking into account the
costs of any actions taken), be severed, divided or otherwise separated from
each other so that a member of the respective Group will own and control their
respective Assets as of the Distribution Date, provided that neither Grace nor
New Grace shall be obligated to make significant expenditures to effect such
separation prior to the Distribution Date.  Actions taken and expenditures
incurred to separate the Shared Facilities shall be subject to the agreement
of Grace, New Grace and SAC.  Such separation may include subdivision of real
property, subleasing or other division of shared buildings or premises and
allocation of shared working capital, equipment and other Assets.  Such
separation shall be effected in a manner that does not unreasonably disrupt
either the Packaging Business or the New Grace Business and minimizes, to the
extent practicable, current and future costs (and losses of tax or other
economic benefits) of the respective Businesses.  With respect to any Asset
that cannot reasonably be separated or otherwise allocated as  provided above,
(i) all right, title and interest of Grace and its Subsidiaries shall be
allocated to the Group as to which such Asset is predominantly used or held
for use or predominantly relates and (ii) the other Group shall have a right
to use such Assets in its Business in a manner consistent with past practice
for a period which is coterminous with the life of the Asset described in (i)
(and the coextensive obligation to pay its allocable share of any costs or
expenses related to such Asset pursuant to the last sentence of this Section
2.01(c)).  To the extent the separation of Assets cannot be achieved in a
reasonably practicable manner, the parties will enter into appropriate
arrangements regarding the shared Asset.  Any costs related to the use of a
shared Asset that is not separated as of the Distribution Date shall be
allocated, with respect to the two-year period beginning immediately after the
Distribution Date, based on the methodology historically used by Grace, and,
for any period thereafter, using such reasonable manner as agreed by New Grace
and Grace.

            (d)   Intellectual Property.  Notwithstanding the foregoing or
anything else contained herein, any intellectual property rights of Grace or
any of its Subsidiaries that are Packco Assets shall be licensed to or
transferred to Packco, as the case may be, as follows.  With respect to
intellectual property rights used or held for use solely in connection with
the Packaging Business, Packco shall have full ownership (to the extent of
Grace's rights therein) of such rights.  Except as otherwise provided in
Schedule 2.01(d), with respect to intellectual property rights that are used
or held for use in both the Packaging Business and the New Grace Business,
title to such rights shall be owned by the New Grace Group and the Packco
Group shall have an exclusive, worldwide, fully paid, perpetual, royalty-free
license to use the intellectual property rights for the field of use described
in the next sentence hereof.  The field of use shall be (i) the businesses
engaged in by Packco and the Packco Group as of the Distribution Date and the
businesses of SAC as of the Distribution Date, including, in each case,
reasonable extensions thereof, provided, however, that such field of use shall
not include the field described in the proviso to the definition of "Packaging
Business" as well as (to the extent not described in such proviso) the
business of (A) closures, closure sealant compositions and multifunctional can
ends which are used on or with rigid containers and (B) coatings, sealants,
compositions and equipment used or held for use in the manufacture of cans and
other rigid containers, in each case including reasonable extensions thereof;
and (ii) notwithstanding (i), with respect to reasonable extensions referred
to in the first part of clause (i) that overlap with the reasonable extensions
described in the proviso in clause (i), the field of use shall include such
overlap but the license therefor shall be non-exclusive and the New Grace
Group shall also have title to use such intellectual property in the area of
overlap.  Such licenses shall not unduly restrict the subsequent transfer or
license (within the applicable field of use) of the intellectual property.
Such arrangements shall not restrict or limit in any way the rights of SAC to
use any intellectual property that is not a Packco Asset.

            (e)   The costs (and other out-of-pocket losses) attributable to
the separation of the Assets, including, without limitation, the Shared
Facilities, shall be allocated pursuant to Section 8.04.

            SECTION 2.02  Certain Foreign Transfers.  (a)  Prior to the
Distribution Date, Grace shall use its reasonable best efforts to effect the
legal separation of the Packco Assets and Packco Liabilities, on the one hand,
from the Grace-Conn. Assets and Grace-Conn. Liabilities, on the other hand,
that are located in jurisdictions outside the United States.  Such separation
may include asset transfers, stock transfers, spin-offs, mergers,
reorganizations, consolidations or other transfers which may be effected
before, simultaneously with or after the Distribution (collectively, the
"Foreign Transfers").  Any Foreign Transfer that occurs after the Distribution
shall be effected pursuant to a binding commitment in existence prior to the
Distribution Date.

            (b)  The Adjusted Foreign Transfer Taxes shall be allocated
between the New Grace Group and the Packco Group as provided in Section 8.04.
Each party shall reimburse the other to the extent that such other party pays
Foreign Transfer Taxes in excess of the amount of Adjusted Foreign Transfer
Taxes allocable to such other party pursuant to Section 8.04.  Such payment
shall, for Tax purposes, be characterized as an adjustment of the New Grace
Capital Contribution.

            (c)  (i)  "Adjusted Foreign Transfer Taxes" shall mean the excess,
if any, of (I) the sum of the Foreign Transfer Taxes, Packco Repatriation Tax
Costs and New Grace Repatriation Tax Costs over (II) the present value using a
discount rate of 5% (or, in the case of value added taxes, the gross value) of
any Tax Benefits (including foreign tax credits for United States federal
income tax purposes ("Foreign Tax Credits") other than Foreign Tax Credits
attributable to Foreign Transfer Taxes or Withholding Taxes that in the
aggregate do not exceed the Tax imposed by the United States and any political
subdivision thereof on the Deemed Repatriation) that may or would arise as a
result of the Foreign Transfers, the payment of the Foreign Transfer Taxes or
the Deemed Repatriations.  Such Tax  Benefits shall be presumed to be utilized
in the first year in which they arise (or are deemed to arise).  All amounts
relating to the calculation of Adjusted Foreign Transfer Taxes and the amount
calculated pursuant to clause (c) of the definition of "New Grace Capital
Contribution" shall be calculated in local currency and translated into U.S.
Dollars at the Foreign Exchange Rate for such currency as of the Distribution
Date.

          (ii)    "Foreign Transfer Taxes" shall mean net Taxes that may be
imposed by any jurisdiction other than the United States or any political
subdivision thereof in connection with the Foreign Transfers (and any Tax net
of associated foreign tax credits imposed by the United States or a political
subdivision thereof on the Foreign Transfer in Venezuela) on any member of the
New Grace Group or the Packco Group; provided, however, that the Foreign NOLs
shall be taken into account in calculating the amount of Foreign Transfer
Taxes.

         (iii)    "Packco Repatriation Tax Costs" and "New Grace Repatriation
Tax Costs", respectively, shall mean the sum of the (I) withholding Taxes that
would be imposed by a foreign jurisdiction on a deemed distribution of Packco
Group Excess Cash to Packco or of New Grace Group Excess Cash to New Grace,
respectively (the "Deemed Repatriations"), on the day immediately following
the Distribution ("Withholding Taxes") and (II) Taxes that would be imposed by
the United States or any political subdivision thereof on a Deemed Repatriation
(without taking into account any net operating loss or other deduction) in
excess of the Foreign Tax Credits of Packco or Grace-Conn., respectively, in
respect of Taxes paid or deemed paid by Packco or Grace-Conn., respectively,
as a result of such Deemed Repatriation ("Deemed Foreign Tax Credits").

          (iv)    "Packco Group Excess Cash" and "New Grace Group Excess
Cash", respectively, shall mean the sum of the amount of Subsidiary Excess
Cash for all Foreign Packco Subsidiaries or Foreign New Grace Subsidiaries.

           (v)    "Subsidiary Excess Cash" shall mean the cash transferred to
a Foreign Packco Subsidiary or Foreign New Grace Subsidiary pursuant to a
Foreign Transfer in excess of the sum of (I) the amount of debt that may be
repaid without penalty plus current accrued unpaid Taxes of such Subsidiary
as of the Distribution Date and (II) the excess of trade and other short-term
payables over trade and other short-term receivables of such Subsidiary
("Excess Short-Term Payables"); provided, however, that each party shall take
steps (including causing the Subsidiary to loan cash to an Affiliate organized
in a foreign jurisdiction to the extent that such Affiliate can use such cash
to repay its debt or to pay current accrued unpaid Taxes  and Excess
Short-Term Payables) and cooperate in good faith to minimize the amount of
Subsidiary Excess Cash, taking into account Tax and financial considerations
as if each party were bearing the full amount of its respective Repatriation
Tax Cost.

          (vi)    The "Foreign NOLs" shall mean net operating losses for
German income tax purposes of Grace GmbH and Grace Multiflex GmbH, and net
operating losses for other foreign income tax purposes of any other Foreign
Packco Subsidiary, attributable to the Pre-Distribution Period to the extent,
in either case, that such net operating losses would be an Overall Tax Benefit
(or Hypothetical Pre-Distribution Overall Tax Benefit), calculated without
regard to any Tax Item arising on the Foreign Transfer involving such
Subsidiary,  that does not exceed the amount of income or gain arising, for
purposes of the applicable foreign income tax, on the Foreign Transfer
involving such Subsidiary.

            (d)  In connection with the Foreign Transfers, certain Assets
(including cash) or Liabilities that, without the agreement of the parties as
required by this Section 2.02(d), would be Grace-Conn. Assets or Grace-Conn.
Liabilities, as the case may be, may be retained by Packco or a Packco
Subsidiary (or Assets or Liabilities that, without the agreement of the
parties as required by this Section 2.02(d), would be Packco Assets or Packco
Liabilities, may be retained by New Grace or a New Grace Subsidiary) if agreed
between Grace and New Grace and reasonably satisfactory to SAC.

            (e)  Neither SAC nor any member of the Packco Group or the New
Grace Group shall take any action, or fail or omit to take any action where
the taking of such action or the failure or omission to take such action would
disturb the tax treatment assumed by the parties in calculating the Foreign
Transfer Taxes and cause any Indemnifiable Loss to a member of the other
Group, including an increase in the amount of Adjusted Foreign Transfer Taxes
borne by the other Group.  Grace agrees to indemnify and hold the Grace-Conn.
Indemnitees harmless, and Grace-Conn. agrees to indemnify and hold the Packco
Indemnitees harmless, from and against any such Indemnifiable Loss without
regard to any limitation contained in Section 8.04.

            (f)  Adjusted Foreign Transfer Taxes shall be recalculated upon
any audit adjustment, Final Determination or any other change (i) of a Foreign
Transfer Tax or another foreign Tax or Tax Item that would change the amount
of Deemed Foreign Tax Credit or otherwise alter Packco Repatriation Tax Costs
or New Grace Repatriation Tax Costs or (ii) that changes the  amount of a
Foreign NOL.  Appropriate payment shall be made between the parties such that
Foreign Transfer Taxes, as so redetermined, and Adjusted Foreign Transfer
Taxes, as so recalculated, are shared according to the principles of Section
2.02(b).

            SECTION 2.03  Certificate of Incorporation; By-laws; Rights Plan.
(a)  Prior to the Distribution Date, Grace shall contribute the capital stock
of Grace-Conn. to New Grace, as well as the capital stock of any other
Subsidiary of Grace formed in connection with the Foreign Transfers that is
not a Packco Subsidiary.  In addition, prior to the Distribution Date, the
parties hereto shall take all action necessary so that, at the Distribution
Date, New Grace's name shall be "W. R. Grace & Co."

            (b)  Prior to the Distribution Date, Grace and New Grace shall
take all action necessary so that the certificate of incorporation and by-laws
of New Grace and the preferred share purchase rights plan of New Grace shall
be in effect as specified by New Grace, each in the form of Exhibits C, D and
E hereto, respectively (with such changes as Grace and New Grace may find
appropriate).

            (c)  Prior to the Distribution Date, Grace and Packco shall take
all action necessary so that the certificate of incorporation and by-laws of
Packco shall be substantially similar to the customary form of certificate of
incorporation and by-laws for a wholly owned Delaware subsidiary and
reasonably acceptable to SAC.

            SECTION 2.04  Issuance of Stock.  Prior to the Distribution Date,
the parties hereto shall take all steps necessary so that the number of shares
of New Grace Common Stock outstanding and held by Grace shall equal the number
of shares of Grace Common Stock outstanding on the Record Date.

            SECTION 2.05  Other Agreements; Shared Facilities.  (a)  Each of
Grace and New Grace shall, prior to the Distribution Date, enter into, or
cause the appropriate members of the Group of which it is a member to enter
into, the Other Agreements in connection with the Distribution, including,
without limitation, agreements with respect to (i) insurance procedures, (ii)
interim services (including, without limitation, services to be provided by
the Shared Regional Headquarters consistent with current operations of the
respective Businesses, and services to be provided by country organizations
to operations of the other Business consistent with past practice), which
shall be charged at allocated cost based on Grace's historical methodology,
subject to applicable tax laws  in any jurisdiction, (iii) intellectual
property licenses as contemplated by Section 2.01, (iv) and other matters as
may be advisable.  The Other Agreements (or, in the case of the forms of
agreement attached hereto, any amendments thereto) shall be on terms
reasonably acceptable to Grace, New Grace and SAC.  Agreements regarding
interim services (including country services) shall generally have a term not
to exceed 24 months (subject to earlier termination on six months' notice (or
such shorter period as does not impose additional costs on the providing
party) by the party receiving the services) and will provide, in the case of
agreements pursuant to which Packco is to provide services to New Grace, for
services at least as extensive as any obligations contained in interim service
and tolling agreements entered into prior to the Distribution Date between
Grace and a third party.  Such Agreements regarding interim services
(including country services) will also provide that any value added taxes
imposed on such services shall be paid and borne, as between the parties, by
the party receiving such services.  The parties shall use reasonable efforts
to conclude the Other Agreements prior to the time the other conditions to the
Distribution have been satisfied.

            (b)  The parties acknowledge and agree that operation by members
of the Packco Group or New Grace Group of the Shared Facilities after the
Distribution Date may continue to require the joint occupation or use by the
parties of certain related premises or facilities (such as waste disposal,
utilities, security and other matters).  The parties shall enter into
appropriate arrangements regarding cost allocation and service provision with
respect to these matters, which allocation shall be as described in Section
2.01(c) and 2.05(a), as applicable.  The agreements described in this
paragraph (b) shall be included in the Other Agreements.

            SECTION 2.06  Financing.  (a)  Prior to the Distribution Date,
Grace and/or Packco shall enter into the Grace Credit Agreement, which shall
be on terms reasonably acceptable to Grace and SAC, and Grace and/or Packco
shall contribute, or cause to be contributed, the New Grace Capital
Contribution to Grace-Conn., all as described in this Section.  No member of
the New Grace Group shall have any Liability or obligation with respect to the
Grace Credit Agreement.  At the election of New Grace and subject to the
consent of Grace and SAC, which will not be unreasonably withheld, a portion
of the New Grace Capital Contribution may be contributed to foreign
Subsidiaries of New Grace.  It is contemplated that the New Grace Capital
Contribution shall be effected as follows; provided, however, that Packco
shall not borrow an amount in excess of the tax basis, for U.S. federal income
tax purposes, of Grace-Conn. in the stock of Packco:  (i) each of Grace and
Packco shall borrow  agreed-upon amounts; (ii) Packco distributes a portion of
the New Grace Capital Contribution to Grace-Conn. which uses such funds to pay
creditors; (iii) the Intragroup Spinoff occurs; (iv) Grace contributes the
remaining amount of the New Grace Capital Contribution to New Grace as well as
the capital stock of Grace-Conn.; and (v) New Grace loans the amount described
in clause (iv) to Grace-Conn. in the form of a security.

            (b)  Prior to the Distribution, Grace-Conn. may consummate a cash
tender offer in accordance with applicable securities laws for any and all
Grace-Conn. Public Debt.  Grace-Conn. may also elect, in its discretion, to
defease or otherwise acquire any portion of the Grace-Conn. Public Debt.  To
the extent that upon consummation of the Distribution, there remains
outstanding (other than to the extent owned by Grace-Conn. or New Grace) in
excess of $50 million in principal amount of the Grace-Conn. Public Debt, New
Grace or Grace-Conn. shall obtain an "evergreen" letter of credit, with an
initial expiration date no sooner than 364 days after the Effective Time, from
a financial institution or group of financial institutions reasonably
acceptable to Grace and SAC for the benefit of Grace with respect to such
outstanding amount from time to time in excess of $50 million.

            The letter of credit shall be in form and substance reasonably
acceptable to SAC and shall entitle Grace to draw thereunder if Grace shall be
required to make (and makes) any payment pursuant to the terms of its
guarantee of any Grace-Conn. Public Debt.  The expiration date of such letter
of credit shall be automatically extended for successive 364-day periods, with
an absolute expiration date on the date that is the 91st day after the date on
which the outstanding principal amount of the Grace-Conn. Public Debt shall
have been reduced to no more than $50 million, unless, prior to such 91st day,
any payments shall have been made that are subject to avoidance pursuant to a
bankruptcy or similar proceeding, in which case such letter of credit shall be
extended (with respect to the applicable payments) until such payments are no
longer subject to such avoidance, unless notice of termination is given by the
issuing bank or banks, in which case Grace shall be entitled to draw
thereunder (whether or not any demand for payment in respect of its guarantee
shall have been made), provided that, to the extent such funds are not used to
make payments on the Grace-Conn. Public Debt, Grace shall hold such proceeds
separate in an interest-bearing escrow account with a financial institution
and pursuant to escrow arrangements reasonably acceptable to Grace-Conn.  To
the extent that the amount held in such escrow account is greater than (i) the
outstanding Grace-Conn. Public Debt minus (ii) $50 million, Grace shall remit
such excess amount to Grace-Conn.  The amount of the letter of  credit may be
reduced from time to time, but shall not at any time be less than the amount
by which the outstanding principal amount of the Grace-Conn. Public Debt
(other than such debt owned by a member of the New Grace Group) exceeds $50
million.

            "Debt Costs" shall mean the costs incurred by Grace or Grace-Conn.
in connection with a tender offer, defeasance, retirement or other acquisition
of Grace-Conn. Public Debt, which costs shall consist of (i) any incremental
costs, fees, expenses and payments incurred in connection with such action,
and in the case of a tender offer shall include all costs, fees, expenses and
payments incurred in connection with a tender offer that are, in the
aggregate, in excess of the outstanding principal amount and accrued interest
of the Grace-Conn. Public Debt so acquired; plus (ii) any costs associated
with terminating or re-negotiating any related interest rate swap agreements
with respect to the amount of Grace-Conn. Public Debt acquired, defeased or
retired; and plus (iii) the costs of the letter of credit described above.

            SECTION 2.07  Grace Recapitalization.  (a)  Immediately prior to
the Effective Time, Grace shall consummate a recapitalization of the Grace
Common Stock, such that each share of Grace Common Stock outstanding as of the
Record Date shall be exchanged for the Per Share Common Consideration and the
Per Share Preferred Consideration (the "Recapitalization").  Options to
purchase shares of Grace Common Stock previously granted by Grace or a
predecessor and outstanding as of the time of the Recapitalization shall be
treated as provided in the Benefits Agreement.  In connection with the
Recapitalization and the Merger, the Grace Certificate of Incorporation shall
be amended so that the par value of the Newco Common Stock will be $.10 per
share, as well as otherwise provided in the Merger Agreement.  Grace shall
retain an Exchange Agent or transfer agent as appropriate and take other
appropriate actions to effect the Recapitalization, including customary
procedures with respect to the exchange of share certificates.

            (b)  No fractional shares of Newco Common Stock or Newco
Convertible Preferred Stock shall be issued in the Recapitalization.  In lieu
of any such fractional shares, each person who would otherwise have been
entitled to a fraction of a share of Newco Common Stock or Newco Convertible
Preferred Stock upon surrender of former shares of Grace Common Stock for
exchange pursuant to the Recapitalization shall be paid an amount in cash
(without interest) equal to such holder's proportionate interest in the net
proceeds from the sale or sales in the open market by the Exchange Agent, on
behalf of all such holders, of the aggregate fractional shares of Newco Common
Stock or Newco Convertible Preferred Stock issued pursuant to  this paragraph.
As soon as practicable following the Distribution Date, the Exchange Agent
shall determine the excess of (i) the number of full shares of Newco Common
Stock or Newco Convertible Preferred Stock, as the case may be, delivered to
the Exchange Agent over (ii) the aggregate number of full shares of Newco
Common Stock or Newco Convertible Preferred Stock to be distributed in respect
of Grace Common Shares (such excess, the "Excess Shares"), and the Exchange
Agent, as agent for the former holders of such Grace Common Shares, shall sell
the Excess Shares at the prevailing prices on the open market.  The sale of
the Excess Shares by the Exchange Agent shall be executed on a public exchange
through one or more firms and shall be executed in round lots to the extent
practicable.  Grace shall pay all commissions, transfer taxes and other
out-of-pocket transaction costs, including the expenses and compensation of
the Exchange Agent, incurred in connection with such sale of Excess Shares.
Until the net proceeds of such sale or sales have been distributed, the
Exchange Agent shall hold such proceeds in trust for such former stockholders.
As soon as practicable after the determination of the amount of cash to be
paid in lieu of any fractional interests, the Exchange Agent shall make
available in accordance with this Agreement such amounts to such former
stockholders.

            SECTION 2.08  Registration and Listing.  Prior to the Distribution
Date:

            (a)  The parties shall take such efforts regarding the
Registration Statements and the Joint Proxy Statement as is provided in the
Merger Agreement.  After such Registration Statements become effective, Grace
shall cause the Joint Proxy Statement and the information statement (or
prospectus, as the case may be) for the New Grace Common Stock forming a part
of the Registration Statement for New Grace to be delivered to all holders of
record of Grace Common Stock as of the record date for the meeting of Grace
shareholders to which the Joint Proxy Statement relates.

            (b)  The parties hereto shall use reasonable efforts to take all
such action as may be necessary or appropriate under state securities and blue
sky laws in connection with the transactions contemplated by this Agreement.

            (c)  New Grace and Grace shall prepare, and New Grace and Grace
shall file and seek to make effective, an application for the listing of the
New Grace Common Stock on the NYSE, and an application for the listing on the
NYSE of the Newco Common Stock and the Newco Convertible Preferred Stock to be
issued in connection with the Recapitalization and the Merger, in each case
subject to official notice of issuance.

            (d)  The parties hereto shall cooperate in preparing, filing with
the SEC and causing to become effective any registration statements or
amendments thereto which are necessary or appropriate in order to effect the
transactions contemplated hereby or to reflect the establishment of, or
amendments to, any employee benefit plans contemplated hereby or by the
Employee Benefits Agreement requiring registration under the Securities Act.

            SECTION 2.09  Grace and New Grace Boards.  The parties hereto shall
take all steps necessary so that, effective immediately after the
Distribution, the Board of Directors of each of Grace and New Grace, so long
as the common stock of such company is registered under Section 12 of the
Exchange Act, shall at all times be comprised of a majority of independent
directors (other than due to temporary vacancies).

            SECTION 2.10  Transfers Not Effected Prior to the Distribution;
Transfers Deemed Effective as of the Distribution Date.  To the extent that
any transfers contemplated by this Article II shall not have been consummated
on the Distribution Date, including, without limitation, any Foreign
Transfers, the parties shall cooperate to effect such transfers as promptly
following the Distribution Date as shall be practicable.  Nothing herein shall
be deemed to require the transfer of any Assets or the assumption of any
Liabilities which by their terms or operation of law cannot be transferred or
assumed; provided, however, that Grace and New Grace and their respective
Subsidiaries shall cooperate to obtain any necessary consents or approvals for
the transfer of all Assets and Liabilities contemplated to be transferred
pursuant to this Article II.  In the event that any such transfer of Assets or
Liabilities has not been consummated, effective as of and after the
Distribution Date, the party retaining such Asset or Liability shall
thereafter hold such Asset in trust for the use and benefit of the party
entitled thereto (at the expense of the party entitled thereto) and retain
such Liability for the account of the party by whom such Liability is to be
assumed pursuant hereto, and take such other action as may be reasonably
requested by the party to which such Asset is to be transferred, or by whom
such Liability is to be assumed, as the case may be, in order to place such
party, insofar as reasonably possible, in the same position as would have
existed had such Asset or Liability been transferred as contemplated hereby.
As and when any such Asset or Liability becomes transferable, such transfer
shall be effected forthwith.  The parties agree that, as of the Distribution
Date, each party hereto shall be deemed to have acquired complete and sole
beneficial ownership over all of the Assets, together with all rights, powers
and privileges incident thereto, and shall be deemed to have assumed in
accordance with the  terms of this Agreement all of the Liabilities, and all
duties, obligations and responsibilities incident thereto, which such party is
entitled to acquire or required to assume pursuant to the terms of this
Agreement.

            SECTION 2.11  Intercompany Accounts and Distribution Payments.
After the Distribution Date, the parties shall be obligated to pay only those
intercompany accounts between members of the New Grace Group and members of
the Packco Group that arose in connection with transfers of goods and services
in the ordinary course of business, consistent with past practices (which the
parties shall use reasonable efforts to settle prior to the Distribution Date),
and all other intercompany accounts shall be settled without transfer of
non-financial assets as of the Distribution Date.


                                ARTICLE III

                             THE DISTRIBUTION

            SECTION 3.01  Record Date and Distribution Date.  Subject to the
satisfaction of the conditions set forth in Section 8.01(a), the Board of
Directors of Grace, in its sole discretion and consistent with the Merger
Agreement, shall establish the Record Date and the Distribution Date and any
appropriate procedures in connection with the Distribution.

            SECTION 3.02  The Agent.  Prior to the Distribution Date, New Grace
shall enter into an agreement with the Agent providing for, among other
things, the payment of the Distribution to the holders of Grace Common Stock
in accordance with this Article III.

            SECTION 3.03  Delivery of Share Certificates to the Agent.  Prior
to the Distribution Date, Grace shall deliver to the Agent a share certificate
representing (or authorize the related book-entry transfer of) all of the
outstanding shares of New Grace Common Stock to be distributed in connection
with the payment of the Distribution.  After the Distribution Date, upon the
request of the Agent, New Grace shall provide all certificates for shares (or
book-entry transfer authorizations) of New Grace Common Stock that the Agent
shall require in order to effect the Distribution.

            SECTION 3.04  The Distribution.  Subject to the terms and
conditions of this Agreement, New Grace shall instruct the Agent to
distribute, as of the Distribution Date, one share of New Grace Common Stock
in respect of each share of Grace Common  Stock held by holders of record of
Grace Common Stock on the Record Date.


                                ARTICLE IV

                       SURVIVAL AND INDEMNIFICATION

            SECTION 4.01  Survival of Agreements.  All covenants and agreements
of the parties hereto contained in this Agreement shall survive the
Distribution Date.

            SECTION 4.02  Indemnification.  (a)  Except as specifically
otherwise provided in the Other Agreements, the New Grace Group shall
indemnify, defend and hold harmless the Packco Indemnitees from and against
(i) all Indemnifiable Losses arising out of or due to the failure or alleged
failure of any member of the New Grace Group (x) to pay any Grace-Conn.
Liabilities (including, without limitation, all Liabilities specifically
excluded from the definition of Packco Liabilities herein), whether such
Indemnifiable Losses relate to events, occurrences or circumstances occurring
or existing, or whether such Indemnifiable Losses are asserted, before or
after the Distribution Date, or (y) to perform any of its obligations under
this Agreement (including the obligation to effect the transfers as provided
in the last sentence of Section 2.01(a)); (ii) all Indemnifiable Losses
arising out of or based upon any untrue statement or alleged untrue statement
of a material fact, or omission or alleged omission to state a material fact
required to be stated, in the Registration Statements or the Joint Proxy
Statement or any preliminary or final form thereof or any amendment thereto,
or necessary to make the statements therein not misleading, except that such
indemnifications shall not apply to any Indemnifiable Losses that arise out of
or are based upon any statement or omission, or alleged statement or omission,
in any of the portions of the Registration Statements or the Joint Proxy
Statement, or any preliminary or final form thereof or any amendment thereto,
solely with respect to information relating to SAC supplied by SAC
specifically for use in the preparation thereof or relating to Newco after the
Merger; and (iii) all Indemnifiable Losses arising from or relating to all
existing litigation brought by pre-Merger shareholders of Grace acting in such
capacity and all litigation to be brought by pre-Merger shareholders of Grace
acting in such capacity and relating to any events or transactions occurring
prior to the Effective Time or to the transactions contemplated by the
Transaction Agreements.

            (b)  Except as specifically otherwise provided in the Other
Agreements, the Packco Group shall indemnify, defend and  hold harmless the
New Grace Indemnitees from and against (i) all Indemnifiable Losses arising
out of or due to the failure or alleged failure of any member of the Packco
Group to pay any Packco Liabilities or to perform any of its obligations under
this Agreement after the Distribution Date; and (ii) all Indemnifiable Losses
arising out of or based upon any untrue statement or alleged untrue statement
of a material fact, or omission or alleged omission to state a material fact
required to be stated, in any portion of the Registration Statements or the
Joint Proxy Statement (or any preliminary or final form thereof or any
amendment thereto) solely with respect to information relating to SAC supplied
by SAC specifically for use in the preparation thereof or relating to Newco
after the Merger (including the pro forma financial information relating to
Newco contained in the Registration Statements (other than the historical
information relating to Grace and the Packaging Business)), or necessary to
make the statements therein not misleading.

            (c)  If any Indemnity Payment required to be made hereunder or
under any Other Agreement is denominated in a currency other than United
States dollars, such payment shall be made in United States dollars and the
amount thereof shall be computed using the Foreign Exchange Rate for such
currency determined as of the date on which such Indemnity Payment is made.

            (d)  Notwithstanding anything to the contrary set forth herein,
indemnification relating to any arrangements between any member of the Packco
Group and any member of the New Grace Group for the provision after the
Distribution of goods and services in the ordinary course shall be governed by
the terms of such arrangements and not by this Section or as otherwise set
forth in this Agreement and the Other Agreements.

            SECTION 4.03  Procedures for Indemnification for Third-Party
Claims.  (a)  Grace shall, and shall cause the other Packco Indemnitees to,
notify New Grace in writing promptly after learning of any Third-Party Claim
for which any Packco Indemnitee intends to seek indemnification from New Grace
under this Agreement.  New Grace shall, and shall cause the other New Grace
Indemnitees to, notify Grace in writing promptly after learning of any
Third-Party Claim for which any New Grace Indemnitee intends to seek
indemnification from Grace under this Agreement.  The failure of any
Indemnitee to give such notice shall not relieve any Indemnifying Party of its
obligations under this Article except to the extent that such Indemnifying
Party or its Affiliate is actually prejudiced by such failure to give notice.
Such notice shall describe such Third-Party  Claim in reasonable detail
considering the Information provided to the Indemnitee.

            (b)  Except as otherwise provided in paragraph (c) of this
Section, an Indemnifying Party may, by notice to the Indemnitee and to Grace,
if New Grace is the Indemnifying Party, or to the Indemnitee and New Grace, if
Grace is the Indemnifying Party, at any time after receipt by such
Indemnifying Party of such Indemnitee's notice of a Third-Party Claim,
undertake (itself or through another member of the Group of which the
Indemnifying Party is a member) the defense or settlement of such Third-Party
Claim.  If an Indemnifying Party undertakes the defense of any Third-Party
Claim, such Indemnifying Party shall thereby admit its obligation to indemnify
the Indemnitee against such Third-Party Claim, and such Indemnifying Party
shall control the investigation and defense or settlement thereof, and the
Indemnitee may not settle or compromise such Third-Party Claim, except that
such Indemnifying Party shall not (i) require any Indemnitee, without its
prior written consent, to take or refrain from taking any action in connection
with such Third-Party Claim, or make any public statement, which such
Indemnitee reasonably considers to be against its interests, nor (ii) without
the prior written consent of the Indemnitee and of Grace, if the Indemnitee
is a Packco Indemnitee, or the Indemnitee and of New Grace, if the Indemnitee
is a New Grace Indemnitee, consent to any settlement that does not include as
a part thereof an unconditional release of the Indemnitees from liability with
respect to such Third-Party Claim or that requires the Indemnitee or any of
its Representatives or Affiliates to make any payment that is not fully
indemnified under this Agreement or to be subject to any non-monetary remedy;
and subject to the Indemnifying Party's control rights, as specified herein,
the Indemnitees may participate in such investigation and defense, at their
own expense.  Following the provision of notices to the Indemnifying Party,
until such time as an Indemnifying Party has undertaken the defense of any
Third-Party Claim as provided herein, such Indemnitee shall control the
investigation and defense or settlement thereof, without prejudice to its
right to seek indemnification hereunder.

            (c)  If an Indemnitee reasonably determines that there may be
legal defenses available to it that are different from or in addition to those
available to its Indemnifying Party which make it inappropriate for the
Indemnifying Party to undertake the defense or settlement thereof, then such
Indemnifying Party shall not be entitled to undertake the defense or
settlement of such Third-Party Claim; and counsel for the Indemnifying Party
shall be entitled to conduct the defense of  such Indemnifying Party and
counsel for the Indemnitee (selected by the Indemnitee) shall be entitled to
conduct the defense of such Indemnitee, it being understood that both such
counsel shall cooperate with each other to conduct the defense or settlement
of such action as efficiently as possible.  The above provisions of this
paragraph (c) shall not apply to Third-Party Claims relating to asbestos
claims described in the proviso to the definition of Packco Liabilities.
Rather, with respect to such asbestos claims, with the consent of Grace-Conn.,
which shall not be unreasonably withheld, counsel for the Indemnifying Party
shall be entitled to conduct the defense of such Third-Party Claim to the
extent the legal defenses available to the Indemnifying Party and the
Indemnitee are substantially similar, but counsel for the Indemnitee shall be
entitled to assert and conduct its own defense to the extent, but only to the
extent, of any additional legal defenses available to it.

            (d)  In no event shall an Indemnifying Party be liable for the
fees and expenses of more than one counsel for all Indemnitees (in addition to
its own counsel, if any) in connection with any one action, or separate but
similar or related actions, in the same jurisdiction arising out of the same
general allegations or circumstances.

            (e)  New Grace shall, and shall cause the other New Grace
Indemnitees to, and Grace shall, and shall cause the other Packco Indemnitees
to, make available to each other, their counsel and other Representatives, all
information and documents reasonably available to them which relate to any
Third-Party Claim, and otherwise cooperate as may reasonably be required in
connection with the investigation, defense and settlement thereof, subject to
the terms and conditions of a mutually acceptable joint defense agreement.
Any joint defense agreement entered into by New Grace or Grace with any third
party relating to any Third-Party Claim shall provide that New Grace or Grace
may, if requested, provide information obtained through any such agreement to
the New Grace Indemnitees and/or the Packco Indemnitees.

            SECTION 4.04  Remedies Cumulative.  The remedies provided in this
Article IV shall be cumulative and shall not preclude assertion by any
Indemnitee of any other rights or the seeking of any other remedies against
any Indemnifying Party.  However, the procedures set forth in Section 4.03
shall be the exclusive procedures governing any indemnity action brought under
this Agreement, except as otherwise specifically provided in any of the Other
Agreements.


                                 ARTICLE V

                       CERTAIN ADDITIONAL COVENANTS

            SECTION 5.01  Notices to Third Parties.  In addition to the actions
described in Section 5.02, the members of the Packco Group and the members of
the New Grace Group shall cooperate to make all other filings and give notice
to and obtain consents from all third parties that may reasonably be required
to consummate the transactions contemplated by this Agreement, the Merger
Agreement and the Other Agreements.

            SECTION 5.02  Licenses and Permits.  Each party hereto shall cause
the appropriate members of its Group to prepare and file with the appropriate
licensing and permitting authorities applications for the transfer or
issuance, as may be necessary or advisable in connection with the transactions
contemplated by this Agreement, the Other Agreements and the Merger Agreement,
to its Group of all material governmental licenses and permits required for
the members of its Group to operate its Business after the Distribution Date.
The members of the New Grace Group and the members of the Packco Group shall
cooperate and use all reasonable efforts to secure the transfer or issuance of
the licenses and permits.

            SECTION 5.03  Intercompany Agreements.  All contracts, licenses,
agreements, commitments or other arrangements, formal or informal, between any
member of the Packco Group, on the one hand, and any member of the New Grace
Group, on the other hand, in existence as of the Distribution Date, pursuant
to which any member of either Group makes payments in respect of Taxes to any
member of the other Group or provides to any member of the other Group goods
or services (including, without limitation, management, administrative, legal,
financial, accounting, data processing, insurance or technical support), or
the use of any Assets of any member of the other Group, or the secondment of
any employee, or pursuant to which rights, privileges or benefits are afforded
to members of either Group as Affiliates of the other Group, shall terminate
as of the close of business on the day prior to the Distribution Date, except
as specifically provided herein or in the Other Agreements.  From and after
the Distribution Date, no member of either Group shall have any rights under
any such contract, license, agreement, commitment or arrangement with any
member of the other Group, except as specifically provided herein or in the
Other Agreements.

            SECTION 5.04  Guarantee Obligations.  (a)  Grace and New Grace
shall cooperate, and shall cause their respective Groups to cooperate, to
terminate, or to cause a member of the  Packco Group to be substituted in all
respects for any member of the New Grace Group in respect of, all obligations
of any member of the New Grace Group under any Packco Liabilities for which
such member of the New Grace Group may be liable, as guarantor, original
tenant, primary obligor or otherwise.  If such a termination or substitution
is not effected by the Distribution Date, (i) Grace shall indemnify and hold
harmless the New Grace Indemnitees for any Indemnifiable Loss arising from or
relating thereto, and (ii) without the prior written consent of the Chief
Financial Officer, Treasurer or any Assistant Treasurer of New Grace, from and
after the Distribution Date, Grace shall not, and shall not permit any member
of the Packco Group or any of its Affiliates to, renew or extend the term of,
increase its obligations under, or transfer to a third party, any loan, lease,

form and substance to the Chief Financial Officer, Treasurer or any Assistant
Treasurer of New Grace, provided that the limitations in clause (ii) shall not
apply in the event that a member of the Packco Group obtains a letter of

terminated by documentation reasonably satisfactory in form and substance to
the Chief Financial Officer, Treasurer or any Assistant Treasurer of Grace,
provided that the limitations contained in clause (ii) shall  not apply in the
event that a member of the New Grace Group obtains a letter of credit from a
financial institution reasonably acceptable to Grace and for the benefit of
Grace with respect to such obligation of the Packco Group.

            SECTION 5.05  Further Assurances.  In addition to the actions

judgment or enter into any settlement without the approval of Grace, which
approval shall not be unreasonably withheld.

Date, all such books, records and copies shall be the property of Grace.  The
costs and expenses incurred in the provision of records or other information
to a party shall be paid for (including reimbursement of costs incurred by the
providing party) by the requesting party.

            SECTION 6.02  Access to Information.  From and after the
Distribution Date, each of Grace and New Grace shall afford to the other and
to the other's Representatives reasonable access and duplicating rights during
normal business hours to all Information within the possession or control of
such party's Group relating to the other party's Group's pre-Distribution
business, Assets or Liabilities or relating to or arising in connection with
the relationship between the Groups on or prior to the Distribution Date,
insofar as such access is reasonably required for a reasonable purpose,
subject to the provisions below regarding Privileged Information.  Without
limiting the foregoing, Information may be requested under this Section 6.02
for audit, accounting, claims, litigation and Tax purposes, as well as for
purposes of fulfilling disclosure and reporting obligations.

            In furtherance of the foregoing:

            (a)  Each party hereto acknowledges that:  (i)  Each of Grace and
      New Grace (and the members of the Packco Group and the New Grace Group,
      respectively) has or may obtain Privileged Information; (ii) there are a
      number of Litigation Matters affecting each or both of Grace and New
      Grace; (iii) both Grace and New Grace have a common legal interest in
      Litigation Matters, in the Privileged Information and in the
      preservation of the confidential status of the Privileged Information,
      in each case relating to the pre-Distribution business of the Packco
      Group or the New  Grace Group or relating to or arising in connection
      with the relationship between the Groups on or prior to the Distribution
      Date; and (iv) both Grace and New Grace intend that the transactions
      contemplated hereby and by the Merger Agreement and the Other Agreements
      and any transfer of Privileged Information in connection therewith shall
      not operate as a waiver of any potentially applicable privilege.

            (b)  Each of Grace and New Grace agrees, on behalf of itself and
      each member of the Group of which it is a member, not to disclose or
      otherwise waive any privilege attaching to any Privileged Information
      relating to the pre-Distribution business of the New Grace Group or the
      Packco Group, respectively, or relating to or arising in connection with
      the relationship between the Groups on or prior to the Distribution
      Date, without providing prompt written notice to and obtaining the prior
      written consent of the other, which consent shall not be unreasonably
      withheld and shall not be withheld if the other party certifies that
      such disclosure is to be made in response to a likely threat of
      suspension or debarment or similar action; provided, however, that Grace
      and New Grace may make such disclosure or waiver with respect to
      Privileged Information if such Privileged Information relates solely to
      the pre-Distribution business of the Packco Group in the case of Grace
      or the New Grace Group in the case of New Grace.  In the event of a
      disagreement between any member of the Packco Group and any member of
      the New Grace Group concerning the reasonableness of withholding such
      consent, no disclosure shall be made prior to a resolution of such
      disagreement by a court of competent jurisdiction, provided that the
      limitations in this sentence shall not apply in the case of disclosure
      required by law and so certified as provided in the first sentence of
      this paragraph.

            (c)  Upon any member of the Packco Group or any member of the New
      Grace Group receiving any subpoena or other compulsory disclosure notice
      from a court, other governmental agency or otherwise which requests
      disclosure of Privileged Information, in each case relating to
      pre-Distribution business of the New Grace Group or the Packco Group,
      respectively, or relating to or arising in connection with the
      relationship between the Groups on or prior to the Distribution Date,
      the recipient of the notice shall promptly provide to the other Group
      (following the notice provisions set forth herein) a copy of such
      notice, the intended response, and all materials or information relating
      to the other Group that might be disclosed.  In  the event of a
      disagreement as to the intended response or disclosure, unless and until
      the disagreement is resolved as provided in paragraph (b) of this
      Section, the parties shall cooperate to assert all defenses to
      disclosure claimed by either party's Group, and shall not disclose any
      disputed documents or information until all legal defenses and claims of
      privilege have been finally determined.

            SECTION 6.03  Production of Witnesses.  Subject to Section 6.02,
after the Distribution Date, each of Grace and New Grace shall, and shall
cause each member of the Packco Group and the New Grace Group, respectively,
to make available to New Grace or Grace or any member of the New Grace Group or
of the Packco Group, as the case may be, upon written request, such Group's
directors, officers, employees and agents as witnesses to the extent that any
such Person may reasonably be required in connection with any Litigation
Matters, administrative or other proceedings in which the requesting party may
from time to time be involved and relating to the pre-Distribution business of
the Packco Group or the New Grace Group or relating to or in connection with
the relationship between the Groups on or prior to the Distribution Date.

            SECTION 6.04  Retention of Records.  Except as otherwise agreed in
writing, or as otherwise provided in the Other Agreements, each of Grace and
New Grace shall, and shall cause the members of the Group of which it is a
member to, retain all Information in such party's Group's possession or under
its control relating directly and predominantly to the pre-Distribution
business, Assets or Liabilities of the other party's Group until such
Information is at least ten years old or until such later date as may be
required by law, except that if, prior to the expiration of such period, any
member of either party's Group wishes to destroy or dispose of any such
Information that is at least three years old, prior to destroying or disposing
of any of such Information, (a) the party whose Group is proposing to dispose
of or destroy any such Information shall provide no less than 30 days' prior
written notice to the other party, specifying the Information proposed to be
destroyed or disposed of, and (b) if, prior to the scheduled date for such
destruction or disposal, the other party requests in writing that any of the
Information proposed to be destroyed or disposed of be delivered to such other
party, the party whose Group is proposing to dispose of or destroy such
Information promptly shall arrange for the delivery of the requested
Information to a location specified by, and at the expense of, the requesting
party.

            SECTION 6.05  Confidentiality.  Subject to Section 6.02, which
shall govern Privileged Information, from and after the Distribution Date,
each of Grace and New Grace shall hold, and shall use reasonable efforts to
cause its Affiliates and Representatives to hold, in strict confidence all
Information concerning the other party's Group obtained by it prior to the
Distribution Date or furnished to it by such other party's Group pursuant to
this Agreement or the Other Agreements and shall not release or disclose such
Information to any other Person, except its Affiliates and Representatives,
who shall be bound by the provisions of this Section 6.05, and each party
shall be responsible for a breach by any of its Affiliates or Representatives;
provided, however, that any member of the Packco Group or the New Grace Group
may disclose such Information to the extent that (a) disclosure is compelled
by judicial or administrative process or, in the opinion of such Person's
counsel, by other requirements of law, or (b) such party can show that such
Information was (i) available to such Person on a nonconfidential basis (other
than from a member of the other party's Group) prior to its disclosure by the
other party's Group, (ii) in the public domain through no fault of such Person
or (iii) lawfully acquired by such Person from another source after the time
that it was furnished to such Person by the other party's Group, and not
acquired from such source subject to any confidentiality obligation on the
part of such source known to the acquiror.  Notwithstanding the foregoing,
each of Grace and New Grace shall be deemed to have satisfied its obligations
under this Section 6.05 with respect to any Information (other than Privileged
Information) if it exercises the same care with regard to such Information as
it takes to preserve confidentiality for its own similar Information.

            SECTION 6.06  Cooperation with Respect to Government Reports and
Filings.  Grace, on behalf of itself and each member of the Packco Group,
agrees to provide any member of the New Grace Group, and New Grace, on behalf
of itself and each member of the New Grace Group, agrees to provide any member
of the Packco Group, with such cooperation and Information as may be
reasonably requested by the other in connection with the preparation or filing
of any government report or other government filing contemplated by this
Agreement or in conducting any other government proceeding relating to the
pre-Distribution business of the Packco Group or the New Grace Group, Assets
or Liabilities of either Group or relating to or in connection with the
relationship between the Groups on or prior to the Distribution Date.  Such
cooperation and Information shall include, without limitation, promptly
forwarding copies of appropriate notices and forms or other communications
received from or sent to any government authority which relate to the Packco
Group, in the case of the New Grace Group, or the New Grace  Group, in the
case of the Packco Group.  Each party shall make its employees and facilities
available during normal business hours and on reasonable prior notice to
provide explanation of any documents or Information provided hereunder.

Severance Costs and losses of benefits) incurred by Grace, New Grace and/or
any members of their respective Groups (collectively, the "Transaction Costs")
in connection with the transactions contemplated by this Agreement and the
Other Agreements (including the Contribution (and the related transfers,
separations and/or allocations of Assets and Liabilities), the Intragroup
Spinoff, the Distribution and the Recapitalization)); provided that Grace (for

million and 37% of the aggregate amount of all Debt Costs, Adjusted Foreign
Transfer Taxes and Severance Costs; (ii) the lesser of $10 million and 37% of

any such costs upon receipt of reasonable documentation relating to such
costs.  Appropriate payment shall be made between the parties  in respect of
Adjusted Foreign Transfer Taxes on the Distribution Date so that Adjusted

substantive laws of any other jurisdiction) as to all matters, including
matters of validity, construction, effect, performance and remedies.

            SECTION 8.06  Notices.  All notices, requests, claims, demands and
other communications hereunder shall be in writing and shall be given (and

This Agreement and all of the provisions hereof shall be binding upon and

circumstances other than those as to which it has been held invalid or
unenforceable, shall remain in full force and effect and shall in no way be
affected, impaired or invalidated thereby, so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any
manner adverse to any party.

            SECTION 8.12  References; Construction.  References to any

            This EMPLOYEE BENEFITS ALLOCATION AGREEMENT (this "Agreement"),
dated as of [         ], 1997, by and among W. R. Grace & Co., a Delaware
corporation ("Grace"), W. R. Grace & Co.-Conn., a Connecticut corporation and
a wholly owned subsidiary of Grace ("Grace-Conn."), and General Specialty
Chemicals, Inc. (to be renamed W. R. Grace & Co.), a Delaware corporation and a

Delaware corporation ("SAC"), have entered into an Agreement and Plan of
Merger, dated as of [             ], 1997 (the "Merger Agreement"), pursuant
to which, at the Effective Time (as defined therein), a wholly owned
subsidiary of Grace will merge with and into SAC, with SAC being the surviving

            B.  The Distribution Agreement.  The Distribution Agreement dated
as of [         ], 1997, by and among Grace, Grace-Conn. and New Grace (the
"Distribution Agreement") and the Other Agreements (as defined in the
Distribution Agreement) set forth certain transactions that SAC has required
as a condition to its willingness to consummate the Merger, and the purpose of
the Distribution Agreement is to make possible the Merger by divesting Grace
of the businesses and operations to be conducted by New Grace and its
subsidiaries, including New Grace-Conn.

            C.  The Contribution.  Prior to the Effective Time, and subject to
the terms and conditions set forth in the Distribution Agreement, Grace
intends to cause the transfer to a wholly owned subsidiary of Grace-Conn.
("Packco") of certain assets and liabilities of Grace and its subsidiaries
predominantly related to the Packaging Business (the "Contribution"), as
contemplated by the Distribution Agreement and the Other Agreements.

            D.  The Distribution.  Following the Contribution and prior to the
Effective Time, subject to the conditions set forth in the Distribution
Agreement, (i) the capital stock of Packco will be distributed to Grace, (ii)
the capital stock of Grace-Conn. will be contributed to New Grace and (iii)
all of the issued and outstanding shares of the common stock of New Grace
(together with the New Grace Rights, "New Grace Common  Stock") will be
distributed (the "Distribution") to the holders as of the Record Date of the
common stock of Grace, par value $.01 per share ("Grace Common Stock"), other
than shares held in the treasury of Grace, on a pro rata basis.

            E.  This Agreement.  This Agreement is one of the Other Agreements
contemplated by the Distribution Agreement, and its purpose is to set forth
the agreement of Grace, Grace-Conn. and New Grace with respect to certain

                                ARTICLE II

                TRANSFER OF EMPLOYEES; TERMINATION BENEFITS

            SECTION 2.01  Transfer of Employees.  (a)  Grace and New Grace
shall take all steps necessary or appropriate so that all of the Employees of
Grace and its subsidiaries are allocated between the New Grace Group and the
Packco Group in accordance with the principles set forth in the Section
2.01(b), and so that each individual who is so allocated to the Packco Group
is, as of the Distribution Date, an Employee of a member of the Packco Group,
and each other individual who is, as of the Distribution Date, an Employee of
Grace or any of its Subsidiaries is an Employee of a member of the New Grace
Group.

            (b)  In making the allocation provided for in Section 2.01, Grace
and New Grace shall allocate each Employee who is exclusively employed in the
Packaging Business to the Packco Group and each Employee who is exclusively
employed in the New Grace Business to the New Grace Group.  All other
Employees  shall be allocated in a mutually agreeable manner that, to the
extent possible, takes into account the Employees' expertise, experience and
existing positions and duties and does not unreasonably disrupt either the
Packaging Business or the New Grace Business and maximizes the ability of each
of the Packco Group and the New Grace Group to manage and operate their
respective businesses after the Distribution Date, taking into account the
respective needs of such businesses as established by past practice.

            SECTION 2.02  Change of Control Benefits; Termination Benefits.
(a)  No New Grace Employee and no Packco Employee shall be deemed, as a result
of the steps called for by Section 2.01 or otherwise as a result of the
consummation of the transactions contemplated by the Distribution Agreement
and the Merger, to have become entitled to any benefits under any Benefit
Plan, contract, agreement, statute, regulation  or other arrangement that
provides for the payment of severance pay, salary continuation, pay in lieu
of notice, unused vacation pay, or similar benefits in connection with actual
or constructive termination or alleged actual or constructive termination of
employment (collectively, "Termination Benefits").  Without limiting the
generality of the foregoing, none of the transactions contemplated by the
Distribution Agreement and the Merger Agreement constitute a "change in
control" for purposes of any Benefit Plan.  Grace shall take all steps
necessary and appropriate so that any Change in Control Severance Agreement
between Grace and any Packco Employee terminates before the Distribution Date.

            (b)   All Liabilities (other than for Severance Costs as defined
in Section 8.04 of the Distribution Agreement) relating to or arising out of
claims made by or on behalf of New Grace Participants or Packco Participants
for, or with respect to, Termination Benefits relating to the actual or
constructive termination or alleged actual or constructive termination of
employment of any New Grace Employee or Packco Employee with any member of the
Packco Group or the New Grace Group, which claims arise as a result of the
consummation of the transactions contemplated by the Distribution Agreement,
shall be considered other Transaction Costs that are governed by clause (ii)
of the first sentence of Section 8.04 of the Distribution Agreement.

            (c)   Except as specifically provided otherwise in Section 2.02(b)
above and in Section 8.04 of the Distribution Agreement, effective as of the
Distribution Date, the New Grace Group shall assume or retain, as appropriate,
all Liabilities relating to or arising out of claims made by or on behalf of
New Grace Participants for, or with respect to, Termination  Benefits relating
to the actual or constructive termination or alleged actual or constructive
termination of employment of any New Grace Employee with any member of the
Packco Group or the New Grace Group, whether before, on or after the
Distribution Date.  In addition, the New Grace Group shall assume or retain,
as appropriate, all Liabilities (including with respect to Packco Employees)
pursuant to the Change in Control Severance Plan and the Change in Control
Severance Agreements.

            (d)   Except as specifically provided otherwise in Sections
2.02(b) and (c) above and in Section 8.04 of the Distribution Agreement,
effective as of the Distribution Date, the Packco Group shall assume or
retain, as appropriate, all Liabilities relating to or arising out of claims
made by or on behalf of Packco Participants for, or with respect to,
Termination Benefits relating to the actual or constructive termination or
alleged actual or constructive termination of employment of any Packco
Employee with any member of the Packco Group or the New Grace Group, whether
before (in the case of constructive termination), on or after the Distribution
Date.


                                ARTICLE III

                              INCENTIVE PLANS

            SECTION 3.01  Grace LTIP.  (a)  The contingent awards for Current
Performance Periods held by New Grace Participants and Packco Participants
(such contingent awards, the "LTIP - Awards") under the Grace LTIP shall be
adjusted and paid in cash by New Grace in accordance with such methodology as
New Grace determines in its sole discretion.

            (b)   Effective as of the Distribution Date, the New Grace Group
shall assume or retain, as appropriate, all Liabilities relating to or arising
out of awards payable under the Grace LTIP.

            SECTION 3.02  Grace Options.  (a)  New Grace shall assume and
adopt, effective as of the Distribution Date, each of the Grace Stock
Incentive Plans, with such changes as may be necessary to reflect the change
in the issuer of awards thereunder and such other changes as New Grace shall,
in its sole discretion, determine.  As soon as practicable after and effective
as of the Distribution Date, all Grace Options that are then outstanding shall
be adjusted or replaced as set forth in this Section 3.02, or in such other
manner as the parties hereto shall agree.

            (b)  Each such Grace Option that is held by a New Grace Employee
or a Terminated Grace Participant shall be replaced with an option (a "New
Grace Option") to acquire a number of New Grace Common Shares that equals the
number of shares subject to such Grace Option immediately before such
replacement, times the New Grace Ratio (rounded up to the nearest whole
share), with a per-share exercise price that equals the per-share exercise
price of such Grace Option immediately before such replacement, divided by the
New Grace Ratio (rounded up to the nearest one hundredth of a cent).  Each New
Grace Option shall otherwise have the same terms and conditions as the Grace
Option it replaces, except that references to employment by or termination of
employment with Grace and its affiliates shall be changed to references to
employment by or termination of employment with New Grace and its affiliates.
Effective as of the Distribution Date, New Grace shall assume all Liabilities
relating to or arising under the New Grace Options or the Grace Stock Incentive
Plans.

            (c)  Each such Grace Option that is held by a Packco Employee
shall be adjusted so that the number of Newco Common Shares subject to such
Grace Option equals the number of shares subject to such Grace Option
immediately before such adjustment, times the Newco Ratio (rounded down to the
nearest whole share), and the per-share exercise price equals the per-share
exercise price of such Grace Option immediately before such adjustment,
divided by the Newco Ratio (rounded up to the nearest whole cent).  Each Grace
Option as so adjusted shall otherwise have the same terms and conditions as
were in effect before such adjustment.  Effective as of the Distribution Date,
Grace shall retain all Liabilities relating to or arising under the Grace
Options held by Packco Employees.

            SECTION 3.03  Annual Incentive Compensation Plan.  (a)  New Grace
shall pay, or cause to be paid by another member of the New Grace Group, all
bonuses earned by Packco Employees and New Grace Employees for the 1997
calendar year under the AICP, in accordance with the terms of the AICP as
interpreted by New Grace in its sole discretion.  Effective as of the
Distribution Date, the New Grace Group shall assume all Liabilities relating
to or arising under the AICP.

            (b)  Packco Employees shall not be eligible to earn bonuses under
the AICP for 1998 or any subsequent year.  However, if the Distribution Date
occurs later than March 31, 1998, then Grace and New Grace shall use
reasonable best efforts to develop and implement an annual incentive program
for Packco Employees, the cost of which will be shared between the New Grace
Group and the Packco Group in a manner relating to  the relative portions of
the 1998 calendar year that precede and follow the Distribution Date.


                                ARTICLE IV

                         PENSION AND SAVINGS PLANS

            SECTION 4.01  Retirement Plans and Supplemental Retirement Plan.
(a)  Grace, New Grace and Grace-Conn. shall take all steps necessary or
appropriate so that, effective no later than the Distribution Date:  (i) one
or more members of the New Grace Group are the sole sponsors of the Salaried
Retirement Plan, the SERP and the Hourly Non-Union Retirement Plan; and (ii)
one or more members of the Packco Group are the sole sponsors of the Union
Retirement Plan.  Such steps shall include, without limitation, the
appointment or reappointment by New Grace (by action after the Distribution
Date to approve or ratify such appointment or reappointment) of all named
fiduciaries, trustees, custodians, recordkeepers and other fiduciaries and
service providers to the Salaried Retirement Plan, the SERP and the Hourly
Non-Union Retirement Plan, and the appointment or reappointment by Grace of
all named fiduciaries, trustees, custodians, recordkeepers and other
fiduciaries and service providers to the Union Retirement Plan.

            (b)  Effective as of the Distribution Date, the Packco Employees
shall cease accruing benefits under the Salaried Retirement Plan, the SERP and
the Hourly Non-Union Retirement Plan.  As promptly as practicable following the
Distribution Date, and effective as of the Distribution Date, Grace intends to
implement a program for Packco Employees who participated in the Salaried
Retirement Plan before the Distribution Date designed to substantially make up
for any anticipated material adverse impact on them resulting from the
termination of such participation as of the Distribution Date.  Such program
will assume that each such Packco Participant works as an employee until
normal retirement (age 65) and that he or she will achieve a reasonable
investment return on his or her account in the Sealed Air Corporation Profit
Sharing Plan.  Upon the implementation of such program by Grace, New Grace
shall (i) cause the Salaried Retirement Plan to be amended so that, effective
immediately before the Distribution Date: (A) the accrued benefit of each
Packco Employee who is a participant therein is increased by crediting such
Packco Employee with an additional year of service; (B) the accrued benefit of
each such Packco Employee who is at least 40 years old as of the Distribution
Date is also increased by an amount equal to the lesser of (x) 13 percent of
the amount of such accrued benefit (after giving effect to the increase
described in clause (A) of  this sentence) or (y) the increase that results
from crediting such Packco Employee with an additional four years of service,
and (C) the accrued benefits of all such Packco Employees, as so increased,
shall be fully vested as of the Distribution Date; or (ii) provide additional
retirement benefits to such Packco Employees as a group having, in the
aggregate, a value substantially equivalent to the increased benefits
described in clause (i); provided, that the aggregate expense associated with
the benefits described in clause (i) or (ii) (as applicable) shall be limited
to the extent necessary so that the Accrued Benefit Obligation, calculated in
accordance with FAS 87 ("ABO"), of such benefits does not exceed $15 million.
Such ABO shall be determined by Actuarial Sciences Associates ("ASA") in
accordance with the actuarial assumptions set forth in Schedule II hereto and
in a manner consistent with past practice with respect to the Salaried
Retirement Plan.

            (c)  Effective as of the Distribution Date, the New Grace Group
shall assume or retain (as applicable) all Liabilities relating to or arising
under the Salaried Retirement Plan and the SERP, including without limitation
for benefits payable thereunder to Packco Participants.  Effective as of the
Distribution Date, the Packco Group shall assume or retain (as applicable) all
Liabilities relating to or arising under the Union Retirement Plan.

            (d)  (i)  Effective immediately after the Effective Time, Grace
shall establish, cause to be established or designate a defined benefit
pension plan (the "Packco Hourly Non-Union Retirement Plan") to provide
benefits and assume liabilities and accept a transfer of assets from the
Hourly Non-Union Retirement Plan, as provided for in this Section 4.01(d).

                    (ii)      As soon as practicable after the Effective Time,
following (A) the receipt by New Grace of a copy of a favorable determination
letter or Grace's certification to New Grace, in a manner reasonably acceptable
to New Grace, that the Packco Hourly Non-Union Retirement Plan is qualified
under Section 401(a) of the Code and the related trust is exempt from taxation
under Section 501(a) of the Code, and (B) the receipt by Grace of a copy of a
favorable determination letter or New Grace's certification to Grace, in a
manner reasonably acceptable to Grace, that the Hourly Non-Union Retirement
Plan is qualified under Section 401(a) of the Code and the related trust is
exempt from taxation under Section 501(a) of the Code, New Grace shall direct
the trustee of the trust funding the Hourly Non-Union Retirement Plan to
transfer to the trustee of the trust established to fund the Packco Hourly
Non-Union Retirement Plan the amount described in Section 4.01(d)(iii) below.
Such transfer shall be in cash unless otherwise agreed by  Grace and New
Grace.  As of the date of such transfer, and effective immediately after the
Effective Time, the Packco Group and the Packco Hourly Non-Union Retirement
Plan shall assume all Liabilities for benefits payable to Packco Participants
under the Hourly Non-Union Retirement Plan, and the New Grace Group and the
Hourly Non-Union Retirement Plan shall retain no Liabilities for such
benefits.

                    (iii)     The amount transferred pursuant to this Section
4.01(d) shall be an amount equal to (A) less (B), as adjusted by (C); where
(A) equals a portion of the assets of the Hourly Non-Union Retirement Plan
having a fair market value equal to the ABO as of the Distribution Date
attributable to Packco Participants; where (B) equals the aggregate payments
made from the trust funding the Hourly Non-Union Retirement Plan in respect of
Packco Participants from the Effective Time through the date the transfer
occurs; and where (C) equals the amount of the net earnings or losses, as the
case may be, from the Effective Time through the date the transfer occurs, on
the average of the daily balances of the foregoing and based upon the actual
rate of return earned by the Hourly Non-Union Retirement Plan during such
period.  All of the foregoing calculations shall be made by ASA in accordance
with the assumptions set forth on Schedule III hereto.  Grace shall be
entitled to review and comment on such calculations as ASA is in the process
of performing them.  Notwithstanding the foregoing, however, in no event shall
the amount so transferred be less than the amount necessary to comply with,
nor more than the maximum amount permitted by, Section 414(l) of the Code and
the regulations promulgated thereunder, as determined by ASA.

                    (iv)      Grace, New Grace and Grace-Conn. shall, in
connection with the transfer described in this Section 4.01(d), cooperate in
making any and all appropriate filings required under the Code or ERISA, and
the regulations thereunder and any applicable securities laws, and take all
such action as may be necessary and appropriate to cause such transfers to
take place as soon as practicable after the Effective Time.  New Grace and
Grace-Conn. agree, during the period ending with the date of the transfer of
assets to the Packco Hourly Non-Union Retirement Plan, to cause distributions
in respect of Packco Participants to be made in the ordinary course from the
Hourly Non-Union Retirement Plan in accordance with applicable law and
pursuant to plan provisions.

            SECTION 4.02  Savings Plans.  (a)  Grace, New Grace and Grace-Conn.
shall take all steps necessary or appropriate so that, effective no later than
the Distribution Date:  (i) one or more members of the New Grace Group are the
sole sponsors of the Hourly SIP and the Salaried SIP; and (ii) one or  more
members of the Packco Group are the sole sponsors of the Cypress 401(k) Plans
and the Schurpack 401(k) Plan.  Effective as of the Distribution Date, the
Packco Group shall assume all Liabilities relating to or arising under the
Cypress 401(k) Plans and the Schurpack 401(k) Plan.  Such steps shall include,
without limitation, the appointment or reappointment by New Grace (by action
after the Distribution Date to approve or ratify such appointment or
reappointment) of all named fiduciaries, trustees, custodians, recordkeepers
and other fiduciaries and service providers to the Hourly SIP and the Salaried
SIP, and the appointment or reappointment by Grace of all named fiduciaries,
trustees, custodians, recordkeepers and other fiduciaries and service
providers to the Cypress 401(k) Plans and the Schurpack 401(k) Plan.

            (b)  Each of the transfers provided for in this Section 4.02(b)
shall be implemented only if both Grace and New Grace so agree after the
Distribution Date.

                    (i)       Grace, New Grace and Grace-Conn. shall take all
steps necessary or appropriate in order to transfer to a Packco Savings Plan
and the related trust, as soon as practicable after the Effective Time, all
account balances (including the pre-tax, after-tax and rollover account
balances) under each of the Hourly SIP and the Salaried SIP of all Packco
Participants.  Such assets shall be transferred in kind, to the extent elected
by New Grace with the consent of Grace (which consent shall not be unreasonably
withheld), and otherwise shall be made in cash; provided, that in any event,
unless the parties agree otherwise, any outstanding participant loans and FMC
American Depositary Receipts shall be transferred in kind.  It is the
intention of Grace, New Grace and Grace-Conn. to carry out such transfer so
as to preserve, to the extent practicable, the investment elections of
participants as in effect immediately before the transfer, unless the parties
agree otherwise.

                    (ii)      Grace, New Grace and Grace-Conn. shall cooperate
in making all appropriate filings required under the Code or ERISA, and the
regulations thereunder and any applicable securities laws, implementing all
appropriate communications with participants, maintaining and transferring
appropriate records, and taking all such other actions as may be necessary and
appropriate to implement the provisions of this Section 4.02(b) and to cause
the transfers of assets pursuant to this Section 4.02(b) to take place as soon
as practicable after the Effective Time; provided, that each of such transfers
shall take place only after (A) the receipt by New Grace of a favorable
determination letter or Grace's certification, in a manner reasonably
acceptable to New Grace, that the relevant  Packco Savings Plan is qualified
under Section 401(a) of the Code and the related trust is exempt from taxation
under Section 501(a) of the Code, and (B) the receipt by Grace of a favorable
determination letter or New Grace's certification, in a manner reasonably
acceptable to Grace, that the Hourly SIP or the Salaried SIP, as applicable,
is qualified under Section 401(a) of the Code and the related trust is exempt
from taxation under Section 501(a) of the Code.

            (c)  If Grace and New Grace agree to implement the transfers
provided for in Section 4.02(b), subject to the completion of such transfer
and effective as of the Distribution Date, the members of the Packco Group and
the SAC Savings Plan shall assume all Liabilities to or relating to Packco
Participants relating to or arising under the Hourly SIP and the Salaried SIP.
Effective as of the Distribution Date, the New Grace Group shall assume or
retain (as applicable) all Liabilities relating to or arising under the Hourly
SIP and the Salaried SIP, including without limitation for benefits payable
thereunder to Packco Participants, that are not assumed by the Packco Group
and the relevant Packco Savings Plan pursuant to the preceding sentence.

            SECTION 4.03  Qualification of Plans.  The New Grace Group shall
be responsible for all Liabilities incurred by the Packco Group as a result
of the failure of any of the Hourly Non-Union Retirement Plan, the Union
Retirement Plan, the Hourly SIP, the Salaried SIP, the Cypress 401(k)
Plans or the Schurpack 401(k)  Plan to be qualified under Section 401(a) of
the Code on or before the date assets are transferred from such Plan to a
Packco Benefit Plan, or the date sponsorship of such Plan is assumed by any
member of the Packco Group, as applicable.  The Packco Group shall be
responsible for all Liabilities incurred by the New Grace Group as a result
of the failure of the Packco Hourly Non-Union Retirement Plan or any Packco
Savings Plan to be qualified under Section 401(a) of the Code on or before
the date assets are transferred to such Plan from a New Grace Benefit Plan.
The parties hereto agree that to the extent any of them becomes aware that
any such Plan fails or may fail to be so qualified, it shall notify the
other parties and the parties shall cooperate and use best efforts to avoid
such disqualification, including using the Internal Revenue Service's
Voluntary Compliance Resolution program or similar programs, and taking any
steps available pursuant to such program to avoid disqualification, as
determined by the party who is made responsible under this Section 4.03 for
the Liabilities that would result from such disqualification (and the
Liabilities for which such party is responsible shall include all costs and
expenses resulting from such steps, including fines, penalties,
contributions, attorneys' fees and expenses and administrative expenses).


                                 ARTICLE V

                        WELFARE AND OTHER BENEFITS

            SECTION 5.01  Benefits for Active Employees.  (a)  Grace, New
Grace and Grace-Conn. shall take all steps necessary or appropriate so
that, effective no later than the Distribution Date, one or more members of
the Packco Group are the sole sponsors of the Packco Health Plan.  Such
steps shall include, without limitation, the appointment or reappointment
by Grace of all named fiduciaries, trustees, custodians, recordkeepers and
other fiduciaries and service providers to the Packco Health Plan, to the
extent such appointments or reappointments are necessary.

            (b)  Effective as of the Distribution Date, the New Grace Group
shall assume or retain (as applicable) all Liabilities relating to or arising
out of claims for benefits under U.S. Welfare Plans by New Grace Participants
and Terminated Grace Participants, whenever such claims are incurred, and (ii)
by Packco Participants to the extent such claims are incurred before the
Distribution Date and reported within 365 days thereafter.  Effective as of
the Distribution Date, the Packco Group shall assume or retain (as applicable)
all Liabilities relating to or arising out of all other claims for benefits
under U.S. Welfare Plans by Packco Participants, except as specifically
provided in Section 5.02.

            SECTION 5.02  Retiree Welfare Benefits.  Effective as of the
Distribution Date, the New Grace Group shall assume all Liabilities for
providing post-retirement medical and life insurance benefits under U.S.
Welfare Plans sponsored by Grace or any of its subsidiaries before the
Distribution Date or any members of the New Grace Group on or after the
Distribution Date, to:  (i) Terminated Grace Participants; (ii) Packco
Participants who would have been eligible to receive such benefits if they had
retired at any time on or before the first anniversary of the Distribution
Date (regardless of when they actually do retire); and (iii) any New Grace
Participants who become eligible for such benefits after the Distribution Date
pursuant to the Grace Severance Pay Plan as a result of a termination of
employment as of the Distribution Date.  Effective as of the Distribution
Date, the Packco Group shall provide Packco Participants who retire after the
Distribution Date for whom the New Grace has not assumed Liabilities for
providing post-retirement medical and life insurance benefits pursuant to the
preceding sentence with such benefits pursuant to one or more group insurance
or group self-insured programs; provided, that the Packco Group may require
such Packco Participants to bear the entire cost of such benefits, together
with a reasonable fee for their allocable share of the Packco Group's costs of
administering such programs.

            SECTION 5.03  Severance.  The Packco Group shall adopt, effective
as of the Distribution Date, and shall maintain in effect without amendment
adverse to participants, at least through the first anniversary of the
Distribution Date, a severance plan providing Packco Employees with severance
benefits as outlined in Exhibit A hereto.

            SECTION 5.04  Split Dollar Plan; Deferred Compensation Plan; Salary
Protection Plan.  Effective as of the Distribution Date, each Packco Employee
who participates in the Split Dollar Plan, the Deferred Compensation Plan or
the Salary Protection Plan shall be treated as a terminated participant under
such Plan, and shall have the same options with respect to such Plan as are
available to any other participant in such Plan upon termination of
employment, in accordance with the terms of such Plan as in effect immediately
before the Distribution Date.  Effective as of the Distribution Date, the New
Grace Group shall assume all Liabilities relating to or arising under the
Split Dollar Plan, the Deferred Compensation Plan and the Salary Protection
Plan.

            SECTION 5.05  Dependent Care and Medical Expense Plans.  (a)
Grace, New Grace and Grace-Conn. shall take all steps necessary or appropriate
so that, effective no later than the Distribution Date, one or more members of
the New Grace Group are the sole sponsors of the Grace Dependent Care Plan and
the Grace Medical Expense Plan, and the New Grace Group shall assume all
Liabilities under such Plans.  Such steps shall include, without limitation,
the appointment or reappointment by New Grace (by action after the Distribution
Date to approve or ratify such appointment or reappointment) of all named
fiduciaries, trustees, custodians, recordkeepers and other fiduciaries and
service providers to such Plans, to the extent such appointments or
reappointments are necessary.

            (b)  Grace, New Grace and Grace-Conn. shall take all steps
necessary or appropriate so that, effective no later than the Distribution
Date, one or more members of the Packco Group are the sole sponsors of the
Packco Medical and Dependent Care Expense Plan, and the Packco Group shall
assume all Liabilities under such Plan.  Such steps shall include, without
limitation, the appointment or reappointment by Grace of all named
fiduciaries, trustees, custodians, recordkeepers and other fiduciaries  and
service providers to such Plan, to the extent such appointments or
reappointments are necessary.  No employer contributions to such Plan shall be
made or promised with respect to the 1998 plan year unless the parties
otherwise agree.


                                ARTICLE VI

                              NON-U.S. PLANS

            SECTION 6.01  Non-U.S. Plans Generally.  As soon as practicable
after the date of this Agreement, the parties hereto shall enter into one or
more agreements or memoranda of understanding (collectively, the "Foreign
Plans Agreement") regarding the treatment and allocation of Liabilities
relating to or arising under Benefit Plans (the "Foreign Plans") for Employees
located outside the United States, including without limitation expatriates,
and to expatriate employees located in the United States.  The Foreign Plans
Agreement shall provide for the treatment of each Foreign Plan, which
treatment may include (without limitation) (i) the retention or assumption of
such Foreign Plan by the Packco Group, (ii) the retention or assumption of
such Foreign Plan by the New Grace Group, or (iii) an allocation of the
liabilities and assets (if any) of the Foreign Plan between a Plan (which may
include the Foreign Plan) that is intended to be maintained by the New Grace
Group and a Plan (which may include the Foreign Plan) that is intended to be
maintained by the Packco Group, after the Distribution Date; provided, that
the insurance contracts funding each Insured Foreign Pension Plan (and any
assets related thereto) shall be divided between the appropriate Packco
Benefit Plan and New Grace Benefit Plan by the insurer in accordance with
applicable law, regulation and practice.  Any transfers of assets or
liabilities from a Noninsured Foreign Pension Plan shall be made on the basis
of reasonable methods and assumptions determined by the local actuarial firm
that is, as of the date of this Agreement, serving as the actuary for such
Noninsured Foreign Pension Plan (or another actuarial firm if the parties
hereto so agree) (the "Local Actuary"), in accordance with applicable legal
and regulatory requirements, local practice and the past practice of Grace;
provided, that each of Grace, Grace-Conn. and New Grace shall be entitled to
review such methods and assumptions and object to them if they are
unreasonable, and to review all calculations and determinations of the Local
Actuary for accuracy.  It is the intention of the parties hereto that the
Packco Group will assume or retain Liabilities for Packco Employees under
Foreign Plans and that to the extent permitted and practicable under legal and
regulatory requirements and local practice, assets transferred from Noninsured
Foreign Pension Plans pursuant to the Foreign  Plans Agreement shall equal the
Projected Benefit Obligation, calculated in accordance with FAS 87, for the
liabilities assumed by Packco Benefit Plans pursuant to the Foreign Plans
Agreement.

                                ARTICLE VII

                                  GENERAL

            SECTION 7.01  Preservation of Rights to Amend or Terminate Plans
and to Terminate or Change Terms of Employment.  No provision of this
Agreement shall be construed as a limitation on the rights of any member of the
Packco Group or the New Grace Group to amend or terminate any Benefit Plan or
other plan, program or arrangement relating to employees.  No provision of
this Agreement shall be construed to create a right in any employee or former
employee or beneficiary or dependent of such employee or former employee under
a Benefit Plan which such employee or former employee or beneficiary would not
otherwise have under the terms of the Benefit Plan itself.  Nothing contained
in this Agreement shall confer upon any individual the right to remain an
employee of any member of the Packco Group or the New Grace Group or restrain
any member of the Packco Group or the New Grace Group from changing the terms
and conditions of employment of any individual at any time following the
Distribution Date, except as provided in Section 5.03 of this Agreement.

            SECTION 7.02  Other Liabilities; Guarantee of Obligations.
Effective as of the Distribution Date, the New Grace Group shall assume or
retain (as applicable) all Liabilities relating to or arising out of claims for
compensation and benefits made by or on behalf of any New Grace Participant,
including salary, wages, bonuses, incentive compensation, severance benefits,
separation pay, accrued sick, holiday, vacation, health, dental or retirement
benefits, or other compensation under applicable law or otherwise, relating to
or arising out of employment by Grace or any of its subsidiaries before the
Distribution Date or employment by any member of the New Grace Group on or
after the Distribution Date.  Effective as of the Distribution Date, the
Packco Group shall assume or retain (as applicable) responsibility for all
Liabilities relating to or arising out of claims for compensation and benefits
made by or on behalf of any Packco Participant, including salary, wages,
bonuses, incentive compensation, severance benefits, separation pay, accrued
sick, holiday, vacation, health, dental or retirement benefits, or other
compensation under applicable law or otherwise, relating to or arising out of
employment by Grace  or any of its subsidiaries before the Distribution Date
or employment by any member of the Packco Group on or after the Distribution
Date.  Notwithstanding the foregoing, this Section 7.02 shall not apply to any
Liability that is specifically provided for elsewhere in this Agreement.

            SECTION 7.03  Assumption of Plans; Termination of Participation.
Except as specifically provided otherwise in this Agreement, Grace, New Grace
and Grace-Conn. shall take all steps necessary or appropriate so that,
effective no later than the Distribution Date, one or more members of the New
Grace Group are the sole sponsors of all Benefit Plans that are, as of the
date of this Agreement, sponsored by Grace, and the New Grace Group shall
assume or retain (as applicable) all Liabilities relating to or arising under
such Benefit Plans.  Such steps shall include, without limitation and where
appropriate, the appointment or reappointment by New Grace (by action after
the Distribution Date to approve or ratify such appointment or reappointment)
of all named fiduciaries, trustees, custodians, recordkeepers and other
fiduciaries and service providers to such Benefit Plans.  Except as
specifically provided otherwise in this Agreement or in the agreement provided
for in Section 6.01 of this Agreement, the accrual of benefits by Packco
Participants in any New Grace Benefit Plan shall cease not later than the
Distribution Date.

            SECTION 7.04  Information.  The parties hereto shall, before the
Distribution Date or as soon as practicable thereafter, provide each other
with all information as may reasonably be requested and necessary to
administer each Benefit Plan effectively in compliance with applicable law.
Such information shall be provided in the form requested if, at the time of
such request, it exists in such form or can readily be converted to such form.
If a request would require a party providing information to incur any expenses
in order to receive advice from any actuary, consultant or consulting firm,
the information need not be provided unless the requesting party reimburses
the party providing the information for all such expenses.

            SECTION 7.05  Complete Agreement; Coordination with Tax Sharing
Agreement.  (a)  This Agreement, the Exhibits and Schedules hereto and the
agreements and other documents referred to herein, shall constitute the entire
agreement between the parties hereto with respect to the subject matter hereof
(other than the Distribution Agreement, the Merger Agreement and the schedules
and exhibits thereto) and shall supersede all previous negotiations,
commitments and writings with respect to such subject matter.

            (b)   This Agreement, and not the Tax Sharing Agreement,
constitutes the sole agreement of the parties regarding responsibility for any
excise taxes, penalties or similar levies that may be imposed by any taxing
authority on, or with respect to, any Benefit Plan, except as otherwise
specifically provided in the Tax Sharing Agreement with respect to payroll
taxes.

            SECTION 7.06  Governing Law.  This Agreement shall be governed by
and construed and enforced in accordance with the laws of the State of
Delaware (other than the laws regarding choice of laws and conflict of laws
that would apply the substantive laws of any other jurisdiction) as to all
matters, including matters of validity, construction, effect, performance and
remedies, except to the extent preempted by federal law.

            SECTION 7.07  Notices.  All notices, requests, claims, demands and
other communications hereunder shall be in writing and shall be given as
provided in the Distribution Agreement.

            SECTION 7.08  Successors and Assigns; No Third-Party Beneficiaries.
This Agreement and all of the provisions hereof shall be binding upon and
inure to the benefit of the parties hereto and their successors and permitted
assigns, but neither this Agreement nor any of the rights, interests and
obligations hereunder shall be assigned by any party hereto without the prior
written consent of the other party (which consent shall not be unreasonably
withheld).  Without limiting the generality of the foregoing, it is expressly
acknowledged that at the Effective Time, the Certificate of Incorporation of
Grace will be amended (the "Newco Amendment") to change the name of Grace to
"Sealed Air Corporation" and that references herein to "Grace" include, from
and after the Effective Time, such corporation (which is also referred to in
the Merger Agreement as Newco).  Accordingly, to the extent this Agreement
calls for the agreement of "Grace" or of "the parties" from and after the
Effective Time, the agreement of Newco (as defined in the Merger Agreement)
will be required.  This Agreement is solely for the benefit of the parties
hereto and their Subsidiaries and is not intended to confer, nor shall it
confer, upon any other Persons (including New Grace Participants and Packco
Participants) any rights or remedies hereunder.

            SECTION 7.09  Amendment and Modification.  This Agreement may be
amended, modified or supplemented only by a written agreement signed by all of
the parties hereto.

            SECTION 7.10  Counterparts.  This Agreement may be executed in
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

            SECTION 7.11  Interpretation.  The Article and Section headings
contained in this Agreement are solely for the purpose of reference, are not
part of the agreement of the parties hereto and shall not in any way affect
the meaning or interpretation of this Agreement.

            SECTION 7.12  Indemnity Procedures.  The provisions of Article IV
of the Distribution Agreement shall apply with respect to Liabilities
allocated under this Agreement.

            SECTION 7.13  Severability.  If any provision of this Agreement or
the application thereof to any person or circumstance is determined by a court
of competent jurisdiction to be invalid, void or unenforceable, the remaining
provisions hereof, or the application of such provision to persons or
circumstances other than those as to which it has been held invalid or
unenforceable, shall remain in full force and effect and shall in no way be
affected, impaired or invalidated thereby, so long as the economic or legal
substance of the transactions contemplated hereby is not affected in any
manner adverse to any party.

            SECTION 7.14  References; Construction.  References to any
"Article," "Exhibit," "Schedule" or "Section," without more, are to Articles,
Exhibits, Schedules and Sections to or of this Agreement.  Unless otherwise
expressly stated, clauses beginning with the term "including" set forth
examples only and in no way limit the generality of the matters thus
exemplified.

            SECTION 7.15  SAC Reasonable Consent.  The parties hereto agree
that any actions to be taken by Grace, Grace-Conn. or New Grace to implement
the terms of this Agreement that are not specifically required herein that
relate to Packco or the Packaging Business, and any actions that are to be
taken pursuant to this Agreement only by agreement of the parties, must be
reasonably satisfactory to SAC.

            IN WITNESS WHEREOF, the parties hereto have caused this Agreement
to be duly executed as of the date first above written.

                           FILING OF TAX RETURNS
                           ---------------------

            Section 2.1  Manner of Filing.  All Tax Returns filed after the
Distribution Date and the Pre-Distribution Schedules shall be prepared on a
basis which is consistent with the consummation of the transactions as set
forth in the Distribution Agreement, the Grace Tax Matters Certificate, the
Sealed Air Tax Matters Certificate, the Tax Opinions and any opinions,
rulings, agreements or written advice relating to Foreign Transfers (in the
absence of a controlling change in law or circumstances) and shall be filed
on a timely basis (including extensions) by the party responsible for such
filing under this Agreement.  The Pre-Distribution Schedules and all Tax
Returns in respect of a Pre-Distribution Taxable Period or portion, ending
on the Distribution Date of any Straddle Period, that include any member of
the New Grace Group or the Packco Group shall be prepared on the basis of
substantial authority or on a reasonable basis with (if applicable)
appropriate disclosure (each, "Substantial Authority"); provided, however,
that such Schedules and Returns shall be prepared on a basis consistent
with the elections (other than elections relating to carrybacks and
carryforwards described in Section 3.3(a)), accounting methods, conventions
and principles of taxation used for the most recent taxable periods of
members of the New Grace Group for which Tax Returns involving similar Tax
Items have been filed, to the extent that a failure to do so would result
in a Tax Detriment, or a reduction in a Tax Benefit, to a member of the
Packco Group, as long as such consistent position has Substantial
Authority.  All Tax Returns in respect of a Post-Distribution Taxable
Period or portion, beginning after the Distribution Date, of any Straddle
Period, shall be prepared with Substantial Authority; provided, however,
that such Returns shall be prepared on a basis consistent with the
elections (other than elections relating to carrybacks and carryforwards
described in Section 3.3(a)), accounting methods, conventions and
principles of taxation used for the most recent taxable periods of members
of the New Grace Group for which Tax Returns involving similar Tax Items
have been filed, to the extent that a failure to do so would result in a
Tax Detriment, or a reduction in a Tax Benefit, to a member of the other
Group, as long as such consistent position has Substantial Authority.  In
the event of a conflict with respect to a Straddle Period between the
requirements of the immediately preceding sentence and the second preceding
sentence, the second preceding sentence shall prevail.  Subject to the
provisions of this Agreement, all decisions relating to the preparation of
Tax Returns shall be made in the sole discretion of the party responsible
under this Agreement for such preparation.  Grace shall provide Grace-Conn.
with copies of all Tax Returns filed after the Distribution Date that
relate to any member of the New Grace Group.  Grace-Conn. shall provide
Grace with a copy of any portion of a Tax Return necessary to confirm
Grace-Conn.'s entitlement to payment hereunder in respect of a carryback or
refund.

            Section 2.2  Pre-Distribution and Straddle Period Tax Returns.

            (a)  Grace shall prepare and file, or cause to be prepared and
filed, any Tax Returns required to be filed by a member or members of the
New Grace Group or the Packco Group for any Pre-Distribution Taxable Period
and any Straddle Period; provided, however, that Grace-Conn. shall prepare
and file, or cause to be prepared and filed, any Tax Returns relating
solely to a member or members of the New Grace Group or their respective
assets or businesses (such Tax Returns to be prepared and filed, or caused
to be prepared and filed, by Grace, the "Del Prepared Returns", and by
Grace-Conn., the "Conn Prepared Returns", respectively).

            (b)  With respect to any Del Prepared Return that has not been
filed as of the Distribution Date and relates to a Pre-Distribution Taxable
Period or a Straddle Period, Grace-Conn. shall, 25 calendar days before the
due date (including extensions) for such Return, provide Grace with a
schedule (collectively, the "Pre-Distribution Schedules") detailing the
computation of (i) in the case of a Pre-Distribution Taxable Period, the
Tax and/or Overall Tax Benefit and (ii) in the case of a Straddle Period,
the Hypothetical Pre-Distribution Tax and/or Hypothetical Pre-Distribution
Overall Tax Benefit, in either case, attributable to the member or members
of the New Grace Group or the Packco Group included in such Return.  Any
Pre-Distribution Schedule relating to a Pre-Distribution Taxable Period
shall be delivered to Grace in the form of a completed, but unexecuted Tax
Return.  If Grace so requests, Grace-Conn. shall discuss with Grace the
preparation of, and allow Grace periodically to review major issues with
respect to, any Pre-Distribution Schedule.  In the event that Grace
disagrees with any Tax Item reflected (or anticipated to be reflected) on a
Pre-Distribution Schedule and demonstrates (by means of a written
explanation in sufficient detail to permit such conclusion to be verified)
its conclusion that Grace-Conn. has failed to comply with the requirements
of the second sentence of Section 2.1 hereof (a "Consistency/Basis
Disagreement"), Grace-Conn. shall explain its calculation of such Tax Item
within 14 days of receipt of Grace's written explanation.  The parties
shall attempt in good faith mutually to resolve any Consistency/Basis
Disagreements prior to the due date for filing the relevant Tax Return.

            (c)  Whether or not any Consistency/Basis Disagreements or any
other disagreements relating to a Tax Item on a Pre-Distribution Schedule
have been resolved by the applicable due date, Grace shall (i) prepare the
Del Prepared Returns on the basis of, and in a manner consistent with, the
Pre-Distribution Schedules, (ii) provide Grace-Conn. with a copy of each
Del Prepared Return 14 calendar days before such Return is filed and
reflect any comments thereon provided in good faith by Grace-Conn. and
(iii) provide Grace-Conn. with a copy of each Del Prepared Return two
business days after such Return is filed.  In the event that any
Consistency/Basis Disagreements relating to a Pre-Distribution Schedule
have not been resolved prior to the filing of the relevant Tax Return, such
disagreements shall be promptly resolved pursuant to Section 6.7 hereof.

            (d)  The "Hypothetical Pre-Distribution Tax" shall mean the Tax
that would have been due for the taxable period ending on the Distribution
Date if the Distribution Date were the last day of the taxable period.  The
"Hypothetical Pre-Distribution Overall Tax Benefit" shall mean the Overall
Tax Benefit that would have arisen in the taxable period ending on the
Distribution Date if the Distribution Date were the last day of the taxable
period.  Such Tax or Overall Tax Benefit shall be computed by determining
items of income, expense, deduction, loss and credit on a "closing of the
books" basis, reflecting tax accounting principles as of the close of
business on the Distribution Date.

            Section 2.3 Post-Distribution Tax Returns.  Any Tax Return for
a Post-Distribution Taxable Period shall be the responsibility of the New
Grace Group if such Tax Return relates solely to a member or members of the
New Grace Group or their respective assets or businesses, and shall be the
responsibility of the Packco Group if such Tax Return relates solely to a
member or members of the Packco Group or Sealed Air or their respective
assets or businesses.

                               ARTICLE III.

                             PAYMENT OF TAXES

            Section 3.1 Allocation of Tax Liabilities With Respect to
Unfiled Returns.

            (a)  All Taxes shall be paid by the party responsible under this
Agreement for filing the Tax Return pursuant to which such Taxes are due;
provided, however, that

                    (i) in the case of Taxes due with respect to Del
Prepared Returns for Pre-Distribution Taxable Periods or Straddle Periods,
Grace-Conn. shall pay Grace the amount, if any, of the Tax or Hypothetical
Pre-Distribution Tax, as the case may be, if any, reflected in the Pre-
Distribution Schedule relating to such Tax Return attributable to the
member or members of the New Grace Group or the Packco Group included in
such Return.  Such payment shall be made, at Grace-Conn.'s discretion,
either in immediately available funds on the morning of the relevant date
when payment is due to the governmental authority in respect of such Tax
Return or, if not in immediately available funds, two business days prior
to such due date.  Grace shall forward any such payment that it receives
from Grace-Conn. to the appropriate taxing authority.

                    (ii) in the case of Del Prepared Returns for any
taxable period, on the relevant date on which payment is due (or a refund
is received) in respect of such Tax Return, Grace shall pay Grace-Conn. the
amount, if any, of the actual reduction in Taxes, or the actual increase in
the Tax refund, that would have been payable or receivable with respect to
such Tax Return but for any Overall Tax Benefit (or Hypothetical Pre-
Distribution Tax Benefit) that is for the account of Grace-Conn. under
Section 3.2(a)(iii), below.  In the case of a payment by Grace in respect
of a reduction in Taxes, such payment shall be made in immediately
available funds on the morning of the relevant due date or, if not in
immediately available funds, two business days prior to the due date.

                    (iii) the parties intend that, in implementing this
Section 3.1(a), payment and reimbursement between the parties shall reflect
the principles of Section 3.2(a).

              (b)  Notwithstanding anything to the contrary, any Tax Item
resulting from any act or omission not in the ordinary course of business
(other than transactions contemplated by this Agreement, the Distribution
Agreement, the Merger Agreement or the Benefits Agreement) on the part of
any member of the Packco Group or any of the Sealed Air Parties occurring
on the Distribution Date after the Effective Time shall be deemed to arise
in a taxable period which begins after the Distribution Date.

otherwise provided in Article V:

              (a) Indemnities.

or on a Pre-Distribution Schedule, (y) any Tax of any member of the New
Grace Group or a Foreign Packco Subsidiary, in either case, to the extent
attributable to the New Grace Business and (z) 75% (or if the Packco Group

Items (and fees and expenses in Proceedings relating to such adjustments)
that exceeds the Foreign Cap, then 100%) of any increase in Tax of a member
of the Packco Group attributable to an adjustment to a Foreign Packco Tax
Item.

                         (ii)  Grace shall be responsible for any Taxes (x)
of any member of the Packco Group or otherwise relating to the Packaging
Business or the Packaging Assets (except to the extent that Grace-Conn. is
responsible for such Taxes pursuant to clause (i) above) and (y) of any of
the Sealed Air Parties, whether arising before, on or after the
Distribution Date.

                         (iii)  Any Overall Tax Benefit (or Hypothetical
Pre-Distribution Overall Tax Benefit) shall be for the account of Grace-
Conn. to the extent that such Overall Tax Benefit (or Hypothetical Pre-
Distribution Overall Tax Benefit) is attributable to (w)  Grace, Grace-
Conn., Packco, any Foreign New Grace Subsidiary, any current or former
member of the Affiliated Group which was a member prior to the Distribution
Date or any current or former member of the affiliated group for United
States federal income tax purposes of which W.  R.  Grace & Co., a New York
corporation, was the common parent, in each case, for the Pre-Distribution
Period, (x) the Packaging Business of a Foreign Packco Subsidiary for the
Pre-Distribution Period reflected on a Tax Return filed by such Subsidiary
on or before the Distribution Date or on a Pre-Distribution Schedule (other
than the Foreign NOLs), (y) a Pre-Distribution Period of any member of the
New Grace Group or a Foreign Packco Subsidiary, in either case, to the
extent attributable to the New Grace Business (other than the Foreign NOLs)
or (z) any adjustment to a Foreign Packco Tax Item.

Grace or Grace-Conn. is responsible for paying the other party, or entitled
to receive from the other party, in the event of any adjustment, including
a Final Determination, of a Tax Item of a Foreign Packaging Subsidiary
(other than a Tax Item that arises as a result of a Foreign Transfer), Tax
Items that are clearly attributable to the Packaging Business or the New
Grace Business, respectively, shall be allocated to such Business and Tax
Items that are not so attributable shall be allocated in the proportion
that the earnings from operations of such Business operated by such
Subsidiary bears to the total earnings from operations of such Subsidiary,
as reflected in audited financial statements for the most recent, as of the
end of such taxable period, full-year accounting period.  Tax Items so
allocated shall be treated for all purposes of this Agreement as
attributable to the Business to which they are allocated.

                         (v) Timing Adjustments.  In the event of any
adjustment, including a Final Determination, of a Tax Item (the "Adjusted
Item") which results in a Tax Benefit or Tax Detriment for the account of
one party and a corresponding Tax Detriment or Tax Benefit (the
"Corresponding Item") for the account of the other party, then (I) if the
Corresponding Item is a Tax Benefit, the Corresponding Party shall pay the
Adjusted Party and (II) if the Corresponding Item is a Tax Detriment, the
Adjusted Party shall pay the Corresponding Party, in either case, for each
taxable period in which a member of the Group of the party entitled to
payment under this Section 3.2(a)(v) actually realizes the Tax Benefit, in
the case of (I), or the Tax Detriment, in the case of (II), by reason of
the adjustment, an amount equal to such realized Tax Benefit, in the case
of (I), or realized Tax Detriment, in the case of (II), including interest
(computed at a 5% annual rate) from the original due date (without
extensions) for filing of the Return for such taxable period through the
date of payment under this Section 3.2(a)(v).

              (b)  Final Determinations.  In the case of any Final
Determination regarding a Tax Return, any Tax Deficiency shall be paid to
the appropriate taxing authority by, and any Tax Refund received from the
appropriate taxing authority shall be paid to, the party which filed such
Return; provided, however, that whether or not there is a Tax Deficiency or
Tax Refund and whether or not a payment is required to or from the
appropriate taxing authority, Grace shall make payments to, or receive
payments from, Grace-Conn. based upon the following principles:

                         (i) Grace-Conn. shall make a payment to Grace in an
amount equal to (x) any increase in the Tax of any of the Sealed Air
Parties or any member of the Packco Group resulting from any adjustment to
a New Grace Tax Item and (y) 75% (or, if the Packco Group has borne an
amount of Tax in respect of adjustments to Foreign Packco Tax Items (and
fees and expenses in Proceedings relating to such adjustments) that exceeds
the Foreign Cap, then 100%) of any increase in the Tax of any of the Sealed
Air Parties or any member of the Packco Group resulting from any adjustment
to a Foreign Packco Tax Item, in either case (x) or (y), together with any
Interest relating thereto that is or has been imposed by the relevant
taxing authority (or would have been imposed but for an offsetting
Packaging Tax Item).

                          (ii)  Grace shall pay to Grace-Conn. an amount
equal to (x) any decrease in the Tax of any of the Sealed Air Parties or
any member of the Packco Group resulting from any adjustment to a New Grace
Tax Item and (y) any decrease in the Tax of any of the Sealed Air Parties
or any member of the Packco Group resulting from any adjustment to a
Foreign Packco Tax Item, in either case (x) or (y), together with any
Interest relating thereto that is or has been paid by the relevant taxing
authority (or would have been paid but for an offsetting Packaging Tax
Item).

                          (iii)  The parties intend that, in implementing this
Section 3.2(b), payment and reimbursement between the parties shall reflect
the principles of Section 3.2(a).

                          (iv)  Payments otherwise required to be made
under this Section 3.2(b) with respect to a single Final Determination
shall be netted and offset against each other so that either Grace shall
make a payment to Grace-Conn. or Grace-Conn. shall make a payment to Grace,
but not both.

                  (c) Calculation and Payment of Amounts.

                        (i)  All calculations and determinations required
to be made pursuant to this Article III shall initially be made by the
party obligated to make such payment (the "Payor") in its good faith.  If
the party entitled to receive a payment (the "Payee") so requests, the
Payor shall present its calculations and determinations to the Payee in
writing.  The Payee shall be deemed to consent to such calculations and
determinations unless the Payee notifies the Payor in writing within 30
days of receiving such calculations and determinations.  If the Payee
disagrees with the Payor's calculations and determinations, the parties
shall attempt in good faith mutually to resolve the disagreement.  In the
event that they cannot so resolve the disagreement, it shall be resolved
promptly pursuant to Section 6.7 hereof.

                         (ii)  For all tax purposes, the parties hereto
agree to treat, and to cause their respect affiliates to treat, (x) any
payment required to be paid to a member of the other Group by this
Agreement as an adjustment to the portion of the New Grace Capital
Contribution that is contributed from Grace to New Grace and (ii) any
payment of interest or Taxes (other than U.S.  Federal income taxes) by or
to a taxing authority as taxable or deductible, as the case may be, to the
party entitled under this Agreement to retain such payment or required
under this Agreement to make such payment, in either case except as
otherwise mandated by the law or a Final Determination.  In the event of
such a Final Determination, the payment in question shall be adjusted to
place the parties in the same after-tax position that they would have
enjoyed absent such Final Determination.  Any payment required by this
Agreement that is not made on or before the date required hereunder shall
bear interest, from and after such date through the date of payment, at the
appropriate market interest rate.

                         (iii)  Payment of any amount required to be made
pursuant to this Article III as a result of a Final Determination shall
become due and payable after such Final Determination has been made within
ten business days of the receipt of written notice from the party entitled
to receive such payment to the party required to make such payment.  Any
amounts required to be paid in respect of Taxes or Overall Tax Benefits
pursuant to this Article III shall be adjusted to avoid duplication of
payments and to take into account the sum of any payments previously made
by any member of the Packco Group on or prior to the Distribution Date or
by Grace-Conn. or any other member of the New Grace Group at any time in
respect of such Taxes or Overall Tax Benefits (the "Conn Prior Payments")
and the sum of any payments previously made by any member of the Packco
Group after the Distribution Date in respect of such Taxes or Overall Tax
Benefits (the "Packco Prior Payments").  Appropriate payments will be made
between the parties in the event that the Conn Prior Payments or the Packco
Prior Payments, respectively, exceed the amounts for which Grace-Conn. or
Packco, respectively, is responsible under the principles of Section
3.2(a).

             (d)  Other Tax Liabilities and Refunds.  Any Tax or Tax refund
that is not otherwise covered by Section 3.1 or 3.2(b) shall be allocated,
and payment shall be made by Grace-Conn. or Grace, using the principles of
Sections 3.2(a); provided, however, that any Tax refund (whether or not
governed by Section 3.1 or 3.2(b)) arising as a result of an adjustment of
a Foreign Packco Tax Item shall be allocated in the same manner and to the
same extent as Taxes and expenses in respect of adjustments of Foreign
Packco Tax Items have been borne (it being agreed and understood that to
the extent that the Foreign Cap has been exceeded, such refund shall be
entirely for the benefit of Grace-Conn. and to the extent that refunds are
shared 75% by Grace-Conn. and 25% by Grace the Foreign Cap shall be
increased by the amount refunded to Grace).  Any Tax refund received by one
party that is for the account of the other party shall be paid to such
other party promptly upon receipt thereof.  Any Tax paid by one party that
is the responsibility of the other party shall be reimbursed promptly by
the other party.

            Section 3.3. Carrybacks and Refund Claims.  (a)  Any Tax refund
resulting from the carryback by any member of the New Grace Group of any
Tax Item arising after the Distribution Date to a Pre-Distribution Taxable
Period or a Straddle Period shall be for the account of Grace-Conn., and
Grace shall promptly pay over to Grace-Conn. any such Tax refund that it
receives.  In the event that a member of the New Grace Group, on the one
hand, and a member of the Packco Group or a Sealed Air Party, on the other
hand, are each entitled to carryback a Tax Item to a Pre-Distribution
Taxable Period or a Straddle Period, the respective Tax Items shall be
utilized under the rules of applicable law (which shall be, in the case of
carrybacks to such periods of the Affiliated Group and carrybacks under
foreign or State law with respect to which there is no applicable rule
regarding the priority of such utilization, the rules contained in Treasury
Regulation Section 1.1502-21T).  Any election affecting the carryback or
carryforward of any Tax Item of any member of the New Grace Group, or a
payment to or by such a member under this Agreement in respect of a
carryback or carryforward, including the elections under Section 172(b)(3)
of the Code and Treasury Regulation Sections 1.1502-21T(b)(3) and
1.172-13(c) with respect to the taxable years of the Affiliated Group that
begin on each of January 1, 1997, and January 1, 1998, shall not be made
without the consent of Grace-Conn. and shall be made if Grace-Conn. so
requests.

              (b)  Grace-Conn. shall be permitted to file, and Grace shall
fully cooperate with Grace-Conn. in connection with, any refund claim.  To
the extent that such a refund claim (other than a claim arising from a
carryback) does not result in a Tax refund (or would not result in a refund
if a claim were filed) as the result of an offsetting Packaging Tax Item
(including a Packaging Tax Item carried back to a Pre-Distribution Taxable
Period or a Straddle Period), Grace shall remit to Grace-Conn. the amount
of any decrease in Tax that results or would have resulted from such refund
claim.

            Section 3.4.  Liability for Taxes with Respect to Post-
Distribution Periods.  Unless otherwise specifically provided in this
Agreement or the Distribution Agreement, the New Grace Group shall pay all
Taxes and shall be entitled to receive and retain all refunds of Taxes with
respect to periods beginning after the Distribution Date which are
attributable to the New Grace Business.  Unless otherwise provided in this
Agreement, the Packco Group shall pay all Taxes and shall be entitled to
receive and retain all refunds of Taxes with respect to periods beginning
after the Distribution Date which are attributable to the Packaging
Business.

                                ARTICLE IV.

            INDEMNITY, COOPERATION AND EXCHANGE OF INFORMATION

            Section 4.1.  Breach.  Grace-Conn. shall be liable for and shall
indemnify, defend and hold harmless the Packco Indemnitees from and against,
and Grace shall be liable for and shall indemnify, defend and hold harmless
the New Grace Indemnitees from and against, any payment required to be made as
a result of the breach by a member of the New Grace Group or the Packco Group,
respectively, of any obligation under this Agreement.  If any member of the
Packco Group or the New Grace Group, fails to comply in any respect whatsoever
with any of its responsibilities under this Agreement relating to promptly
forwarding to any member of the other Group (the "Recipient Group") any
communications with and refunds received from any taxing authority
("Forwarding Responsibilities"), then Grace or Grace-Conn., as the case may
be, (the "Forwarding Party") shall be liable for and shall indemnify and hold
the New Grace Indemnitees or the Packco Indemnitees, as the case may be,
harmless from and against any costs or expenses (including, without limitation,
Taxes and reasonably incurred lawyers' and accountants' fees) ("Indemnified
Amount") incurred by or imposed upon any member of the Recipient Group arising
out of, in connection with or relating to such communication; provided,
however, that the liability of the Forwarding Party with respect to any one
such failure shall be equal to that portion of the Indemnified Amount that a
member of the Recipient Group demonstrates is caused (directly or indirectly)
by such failure.

            Section 4.2.  Contests.  (a)  Whenever a party hereto (the
"Indemnitee") becomes aware of the existence of an issue that could increase
the liability for any Tax, or decrease the amount of any refund, of the other
party hereto or any member of its Group or require a payment hereunder (an
"Indemnity Issue"), the Indemnitee shall in good faith promptly give notice to
such other party (the "Indemnitor") of such Indemnity Issue.  The failure of
any Indemnitee to give such notice shall not relieve any Indemnitor of its
obligations under this Agreement, except to the extent that such Indemnitor or
its affiliate is actually materially prejudiced by such failure to give
notice.

              (b)  The Indemnitor and its representatives, at the Indemnitor's
expense, shall be entitled to participate (i) in all conferences, meetings
or proceedings with any taxing authority, the subject matter of which is or
includes an Indemnity Issue in respect of a Pre-Distribution Period and
(ii) in all appearances before any court, the subject matter of which is or
includes an Indemnity Issue in respect of a Pre-Distribution Period.

              (c)  Except as provided in Section 4.2(d), Grace-Conn. shall
have the right to decide as between the parties hereto how any Indemnity
Issue for a Pre-Distribution Taxable Period is to be dealt with and finally
resolved with the appropriate taxing authority and shall control all
Proceedings relating thereto.  Grace agrees to cooperate with Grace-Conn.
in the settlement of any such Indemnity Issue; provided, however, that
Grace-Conn. shall act in good faith in the conduct of such Proceedings and
shall keep Grace reasonably informed of any developments which can
reasonably be expected to affect adversely Grace.  Such cooperation shall
include permitting Grace-Conn. to litigate or otherwise resolve any such
Indemnity Issue.  It is expressly the intention of the parties to this
Agreement to take, and the parties shall take, all actions necessary to
establish Grace-Conn. as the sole agent for Tax purposes of each member of
the Affiliated Group, as if Grace-Conn. were the common parent of the
Affiliated Group, with respect to all combined, consolidated and unitary
Tax Returns of the Affiliated Group for the Pre-Distribution Taxable
Periods.

              (d)  The parties jointly shall represent the interests of (i)
the Affiliated Group in any Proceeding relating to any Straddle Period and
(ii) any Foreign Packco Subsidiary in any Proceeding relating to any
taxable period that involves an Indemnity Issue.  Neither party shall
settle any dispute relating to any such period without the consent of the
other party (which consent shall not be unreasonably withheld); provided,
however, that if either party proposes a settlement and the other party
does not consent thereto, the nonconsenting party shall assume control of
the Proceeding (and bear all subsequently incurred costs, fees and expenses
relating thereto) and the respective liabilities of the parties shall be
determined pursuant to Section 6.7 based on the magnitude and likelihood of
success of the issues involved in the Proceeding, the reasonableness of the
settlement offer, the expense of continuing the Proceeding and other
relevant factors.  Any other disputes regarding the conduct or resolution
of any such Proceeding shall be resolved pursuant to Section 6.7.  All
costs, fees and expenses paid to third parties in the course of such
Proceeding shall be borne by the parties in the same ratio as the ratio in
which, pursuant to the terms of this Agreement, the parties would share the
responsibility for payment of the Taxes asserted by the taxing authority in
its claim or assessment if such claim or assessment were sustained in its
entirety; provided, however, that in the event that any party hereto
retains its own advisors or experts in connection with any Proceeding, the
costs and expenses thereof shall be borne solely by such party.

            Section 4.3.  Cooperation and Exchange of Information.

              (a)  Grace shall, and shall cause each appropriate member of the
Packco Group to, prepare and submit to Grace-Conn., as soon as practicable,
but in no event later than the date that is 30 days after a request from
Grace-Conn.  (i) all information as Grace-Conn. shall reasonably request to
enable Grace-Conn. to file any Conn Prepared Return or prepare any Pre-
Distribution Schedule (which information shall be provided in the form and
of the quality in which comparable information was provided prior to the
Distribution) and (ii) any Del Prepared Return (including any amended
return) for any year within the carryback or carryforward period for an
Overall Tax Benefit or Hypothetical Pre-Distribution Overall Tax Benefit
that is for the account of Grace-Conn. or for any year with respect to
which Grace is entitled to a payment under Section 3.2(a)(v).  Grace-Conn.
shall bear any out-of-pocket marginal expense paid by any member of the
Packco Group in preparing and submitting such information in respect of a
Pre-Distribution Schedule relating to a Pre-Distribution Taxable Period,
and the parties shall share equally any such expenses in respect of a Pre-
Distribution Schedule relating to a Straddle Period.

              (b)  Each party on behalf of itself and each member of its Group,
agrees to provide the other party and the members of such party's Group
with such cooperation and information as the second party or its Group
members shall reasonably request in connection with the preparation or
filing of any Tax Return, Pre-Distribution Schedule or claim for refund not
inconsistent with this Agreement or in conducting any Proceeding in respect
of Taxes.  Such cooperation and information shall include, without
limitation, (i) execution and delivery of a power of attorney by Grace or
any other member of the Packco Group to Grace-Conn. or another member of
the New Grace Group or designation of an officer of Grace-Conn. or another
member of the New Grace Group as an officer of Grace or any other member of
the Packco Group for the purpose of signing Tax Returns, cashing refund
checks and conducting Proceedings if Grace Conn. could not otherwise
exercise its rights under this Agreement with respect to such Returns,
refunds or Proceedings, (ii) promptly forwarding copies of appropriate
notices and forms or other communications received from or sent to any
taxing authority which relate to the Affiliated Group, the Packaging
Business or the New Grace Business and (iii) providing copies of all
relevant portions of Tax Returns, accompanying schedules, related
workpapers, documents relating to rulings or other determinations by taxing
authorities, including, without limitation, foreign taxing authorities, and
records concerning the ownership and Tax basis of property, which either
party may possess.  Each party shall make, and shall cause the members of
the Packco Group to make, their employees and facilities available on a
mutually convenient basis to provide explanation of any documents or
information provided hereunder.

              (c)  Grace and Grace-Conn. agree to retain all Tax Returns,
related schedules and workpapers, and all material records and other
documents as required under Section 6001 of the Code and the regulations
promulgated thereunder relating thereto existing on the date hereof or
created through the Distribution Date, until the expiration of the statute
of limitations (including extensions) of the taxable years to which such
Tax Returns and other documents relate and until the Final Determination of
any payments which may be required in respect of such years under this
Agreement.  Grace-Conn. and Grace agree to advise each other promptly of
any such Final Determination.  Any information obtained under this Section
shall be kept confidential, except as may be otherwise necessary in
connection with the filing of Tax Returns or claims for refund or in
conducting any audit or other proceeding.

              (d)  If (i) any member of the Packco Group fails to provide any
information requested pursuant to this Section 4.3(a) by the dates and in
the manner specified in Section 4.3(a) hereof or (ii) with respect to
information not requested pursuant to Section 4.3(a) hereof, any member of
either Group fails to provide any information requested pursuant to this
Section 4.3, within a reasonable period, then the requesting party shall
have the right to engage a "Big Six" public accounting firm of its choice
to gather such information.  Each party agrees upon two business days'
notice, in the case of a failure to provide information pursuant to Section
4.3 hereof to permit any such "Big Six" public accounting firm full access
to all appropriate records or other information in the possession of any
member of the party's Group during reasonable business hours, and promptly
to reimburse or pay directly all costs and expenses in connection with the
engagement of such public accountants.

              (e)  If any member of either Group supplies information
pursuant to this Agreement and an officer of any member of the other Group
signs a statement or other document under penalties of perjury in reliance
upon the accuracy of such information and so requests, then a duly
authorized officer of the member supplying such information shall certify,
under penalties of perjury, the accuracy and completeness of the
information so supplied.  Grace agrees to indemnify and hold harmless each
New Grace Indemnitee, and Grace-Conn. agrees to indemnify and hold harmless
each Packco Indemnitee, from and against any cost, fine, penalty or other
expense of any kind attributable to the gross negligence or willful
misconduct of a member of the Packco Group, or New Grace Group, as the case
may be, in supplying a member of the other Group with inaccurate or
incomplete information.

                                ARTICLE V.

                  CERTAIN POST-DISTRIBUTION TRANSACTIONS

            Section 5.1.  Sealed Air and Packco Group Covenants.

            Unless, in the case of any of Sections 5.1(a) through (f) below,
Grace has obtained a ruling letter from the IRS or an opinion of nationally
recognized counsel to Grace, in either case, to the effect that, without
material qualification, such act or omission will not adversely affect the
federal income tax consequences of the Distribution to any of Grace, Grace-
Conn. or the stockholders of Grace-Conn., as set forth in the Tax Opinions,
and the substance of, and basis for, such conclusion in such ruling or
opinion is reasonably satisfactory to Grace-Conn. in its good faith solely
with regard to preserving the Tax-Free Status of the Distribution (the
"Ruling/Opinion Exception"):

            (a)  No Sealed Air Party at any time nor any member of the Packco
Group at any time after the Effective Time shall take any action, or fail
or omit to take any action, that would cause any representation made in the
Sealed Air Tax Matters Certificate or the Grace Tax Matters Certificate to
be untrue in a manner that would have an adverse effect on the Tax-Free
Status of the Distribution.

            (b)  Until the first day after the Restriction Period, the Packco
Group shall continue the active conduct of the Packaging Business (the "Active
Packco Business").  The Packco Group shall not liquidate, dispose of, or
otherwise discontinue the conduct of any material portion of the Active Packco
Business.  The Packco Group shall continue the active conduct of the
Packaging Business primarily through officers and employees of the Packco
Group (and not through independent contractors).

            (c)  Until the first day after the Restriction Period, no Sealed
Air Party nor any member of the Packco Group shall sell or otherwise issue
to any Person, or redeem or otherwise acquire from any Person (other than
any member of the Packco Group), any Equity Securities of Grace or any
other member of the Packco Group; provided, however, that purchases that,
in the aggregate, meet the requirements of Section 4.05(1)(b) of Revenue
Procedure 96-30 shall not constitute a redemption or acquisition of stock
of Grace for purposes of this Section 5.1(c).

            (d)  Until the first day after the Restriction Period, no
Sealed Air Party nor any member of the Packco Group shall (i) solicit any
Person to make a tender offer for, or otherwise acquire or sell, the Equity
Securities of Grace, (ii) participate in or support any unsolicited tender
offer for, or other acquisition or disposition of, the Equity Securities of
Grace or (iii) approve or otherwise permit any proposed business
combination or any transaction which, in the case of (i), (ii) or (iii),
individually or in the aggregate, together with the transactions
contemplated under the Distribution Agreement, the Merger Agreement, the
Benefits Agreement and this Agreement, results in one or more Persons
acquiring (other than in acquisitions not taken into account for purposes
of Section 355(e)) directly or indirectly stock representing a 50 percent
or greater interest (within the meaning of Section 355(e) of the Code) in
Grace.  In addition, no Sealed Air Party nor any member of the Packco Group
shall at any time, whether before or subsequent to the expiration of the
Restriction Period, engage in any action described in clauses (i), (ii) or
(iii) of the preceding sentence if it is pursuant to an arrangement
negotiated (in whole or in part) prior to the Distribution, even if at the
time of the Distribution it is subject to various conditions, nor shall any
such Party or member take any action, or fail or omit to take any action,
that would cause Section 355(d) or (e) to apply to the Distribution.

            (e)  Until the first day after the Restriction Period, no
Sealed Air Party nor the members of the Packco Group shall sell, transfer,
or otherwise dispose of or agree to dispose of assets (including, for such
purpose, any shares of capital stock of a Subsidiary) that, in the
aggregate, constitute more than 60% of the gross assets of Packco, nor
shall they sell, transfer, or otherwise dispose of or agree to dispose of
assets (including, for such purpose, any shares of capital stock of a
Subsidiary) that, in the aggregate, constitute more than 60% of the con-
solidated gross assets of the Packco Group.  The foregoing sentence shall
not apply to sales, transfers, or dispositions of assets in the ordinary
course of business.  The percentages of gross assets or consolidated gross
assets of Packco or the Packco Group, as the case may be, sold,
transferred, or otherwise disposed of, shall be based on the fair market
value of the gross assets of Packco and the Packco Group as of the
Effective Time, and for this purpose, the values set forth in the Packaging
Business Disclosure Letter Balance Sheet shall be conclusive.

            (f)  Until the first day after the Restriction Period, neither
Packco nor its Subsidiaries shall voluntarily dissolve or liquidate or engage
in any merger, consolidation or other reorganization.  The foregoing sentence
shall not apply to transactions in which Packco acquires another
corporation, limited liability company, limited partnership, general
partnership or joint venture solely for cash or other consideration that
is not Equity Securities.  Reorganizations of Packco with its Affiliates,
and liquidations of Packco's Affiliates, are not subject to Section 5.1(b)
or this Section 5.1(f) to the extent not inconsistent with the structure
necessary for the Distribution to qualify for Tax-Free Status.

            (g)  Until the first day after the Restriction Period, Grace shall
furnish Grace-Conn. with a copy of any ruling request that Sealed Air, Grace
or any of their Affiliates may file with the IRS and any opinion received that
relates to or otherwise reasonably could be expected to have an effect on the
Tax-Free Status of the Distribution.

                  Section 5.2.  New Grace Covenants.

                  Unless, in the case of any of Sections 5.2(a) through (e)
below, Grace-Conn. has obtained a ruling letter from the IRS or an opinion of
nationally recognized counsel to Grace-Conn., in either case, to the effect
that, without material qualification, such act or omission will not adversely
affect the federal income tax consequences of the Distribution to any of
Grace, Grace-Conn. or the stockholders of Grace-Conn., as set forth in the Tax
Opinions, and the substance of, and basis for, such conclusion in such ruling
or opinion is reasonably satisfactory to Grace in its good faith solely with
regard to preserving the Tax-Free Status of the Distribution:

            (a)  No member of the New Grace Group shall take any action, or fail
or omit to take any action, that would cause any representation made in the
Sealed Air Tax Matters Certificate or the Grace Tax Matters Certificate to
be untrue in a manner that would have an adverse effect on the Tax-Free
Status of the Distribution.

            (b)  Until the first day after the Restriction Period, the New
Grace Group shall continue the active conduct of one of the Active New
Grace Businesses. "Active New Grace Businesses" shall mean each of the
Grace Davison business and the Grace Construction Business.  The New Grace
Group may dispose of, liquidate or discontinue the conduct of the Grace
Davison business or the Grace Construction Products business if it actively
continues the conduct of the other.  The New Grace Group shall continue the
active conduc11zt of at least one of the Active New Grace Businesses primarily
through officers and employees of the New Grace Group (and not through
independent contractors).

            (c)  Until the first day after the Restriction Period, no member of
the New Grace Group shall sell or otherwise issue to any Person, or redeem
or otherwise acquire from any Person (other than any member of the New
Grace Group), any Equity Securities of New Grace or any other member of the
New Grace Group; provided, however, that purchases that, in the aggregate,
meet the requirements of Section 4.05(1)(b) of Revenue Procedure 96-30
shall not constitute a redemption or acquisition of stock of New Grace for
purposes of this Section 5.2(c).

            (d) Until the first day after the Restriction Period, no member of
the New Grace Group shall (i) solicit any Person to make a tender offer for,
or otherwise acquire or sell, the Equity Securities of New Grace, (ii)
participate in or support any unsolicited tender offer for, or other
acquisition or disposition of, the Equity Securities of New Grace or (iii)
approve or otherwise permit any proposed business combination or any
transaction which, in the case of (i), (ii) or (iii), individually or in
the aggregate, together with the transactions contemplated under the
Distribution Agreement, the Merger Agreement, the Benefits Agreement and
this Agreement, results in one or more Persons acquiring (other than in
acquisitions not taken into account for purposes of Section 355(e))
directly or indirectly stock representing a 50 percent or greater interest
(within the meaning of Section 355(e) of the Code) in New Grace.  In
addition, no member of the New Grace Group shall at any time, whether
before or subsequent to the expiration of the Restriction Period, engage in
any action described in clauses (i), (ii) or (iii) of the preceding
sentence if it is pursuant to an arrangement negotiated (in whole or in
part) prior to the Distribution, even if at the time of the Distribution it
is subject to various conditions, nor shall any such member take any
action, or fail or omit to take any action, that would cause Section 355(d)
or (e) of the Code to apply to the Distribution.

            (e)  Until the first day after the Restriction Period, no member of
the New Grace Group shall sell, transfer, or otherwise dispose of or agree to
dispose of assets (including, for such purpose, any shares of capital stock
of a Subsidiary) that, in the aggregate, constitute more than 60% of the
gross assets of New Grace, nor shall they sell, transfer, or otherwise
dispose of or agree to dispose of assets (including, for such purpose, any
shares of capital stock of a Subsidiary) that, in the aggregate, constitute
more than 60% of the consolidated gross assets of the New Grace Group.  The
foregoing sentence shall not apply to sales, transfers, or dispositions of
assets in the ordinary course of business or to a sale, transfer or
disposition of any or all of the Discontinued Businesses and either of the
Active New Grace Businesses; provided, however, that in the event of a
sale, transfer or disposition of one of the Active New Grace Businesses,
the retained Active New Grace Business shall be conducted by a member of
the New Grace Group at substantially the same level as on the Distribution
Date.  The percentages of gross assets or consolidated gross assets of New
Grace or the New Grace Group, as the case may be, sold, transferred, or
otherwise disposed of, shall be based on the fair market value of the gross
assets of New Grace and the New Grace Group as of the Effective Time, and
for this purpose, the values set forth in the [Registration Statements]
shall be conclusive.

            (f)  Until the first day after the Restriction Period, Grace-
Conn. shall furnish Grace with a copy of any ruling request that Grace-
Conn. or any of its Affiliates may file with the IRS and any opinion
received that relates to or otherwise reasonably could be expected to have
an effect on the Tax-Free Status of the Distribution.

                 Section 5.3.  Responsibility for Taxes.

              (a)  Sealed Air and Grace agree to indemnify and hold the
Grace-Conn.  Indemnitees harmless from and against all Indemnifiable Losses
resulting from (x) any Action which causes the Distribution to fail to have
Tax-Free Status or (y) the Merger failing to qualify as a reorganization
under Section 368 of the Code.  An "Action" shall mean any act or omission
which fails to comply with any of the representations in the Sealed Air Tax
Matters Certificate or the covenants in Section 5.1 and any act or omission
which would fail to comply with any of the covenants in Section 5.1 but for
compliance with the Ruling/Opinion Exception.  An "Action" shall also
include an action or omission which would be a breach of the covenant
contained in the first sentence of Section 5.1(d), if such covenant were in
effect until the day which is five years after the Effective Time instead
of until the first day after the Restriction Period.

                  (b)  Grace-Conn. agrees to indemnify and hold the
Packco Indemnitees harmless from and against any Tax resulting from the
failure of the Distribution to have Tax-Free Status, except where such failure
is attributable to an Action.

                  (c)  For purposes of Sections 5.1 and 5.2 hereof, when a tax
opinion or ruling of one party (the "Transaction Party") is required to be
reasonably satisfactory to the other party (the "Reviewing Party"), the
Reviewing Party at the request of the Transaction Party shall designate
nationally recognized counsel to review such opinion or ruling without
revealing the substance of the underlying transaction to the Reviewing Party
and the concurrence of such outside counsel to the sufficiency of such opinion
or ruling shall constitute "reasonable satisfaction" to the Reviewing Party
for purposes of this Agreement.

                 Section 5.4. Injunction.  The parties hereto agree that the
payment of monetary compensation would not be an adequate remedy for a
breach of the obligations contained in Article V hereof, and each party
consents to the issuance and entry of an injunction against the taking of
any action by it or a member of its Group that would constitute such a
breach; provided, however, that the foregoing shall be without prejudice to
and shall not constitute a waiver of any other remedy either party may be
entitled to at law or at equity hereunder.

Conn. or Grace, respectively, or its respective designees shall be received

      GRACE TO MERGE CRYOVAC (REGISTERED) BUSINESS WITH SEALED AIR IN
          TAX-FREE TRANSACTION CREATING TWO NEW PUBLIC COMPANIES

        NEW SEALED AIR, LED BY T.J. DERMOT DUNPHY, WILL BE WORLD'S
            LEADING PROTECTIVE AND SPECIALTY PACKAGING COMPANY

        GRACE SHAREHOLDERS TO OWN 63% OF NEW PACKAGING COMPANY AND
      RETAIN 100% OWNERSHIP OF NEW GRACE SPECIALTY CHEMICALS COMPANY

            TRANSACTION VALUE TO GRACE AND ITS SHAREHOLDERS IS
           APPROXIMATELY $5 BILLION, INCLUDING $1.2 BILLION CASH
                       CONTRIBUTION TO THE NEW GRACE


      BOCA RATON, FL AND SADDLE BROOK, NJ, August 14,1997 -- W. R. Grace & Co.
(NYSE:  GRA) and Sealed Air Corporation (NYSE:  SEE) today announced they have
entered into a definitive agreement to combine Grace's packaging business with
Sealed Air to create a new publicly owned company, to be called Sealed Air,
that will be the world's leading protective and specialty packaging company,
with annual sales in excess of $2.5 billion.

      The transaction, tax-free to both companies and their shareholders, is
expected to be completed in early 1998.  Prior to the merger, Grace's
specialty chemicals businesses will become a new publicly traded company that
will be spun off to Grace shareholders.  The new company will consist of Grace
Davison, Grace Construction Products and DAREX Container Products, have annual
sales of approximately $1.5 billion and retain the Grace name.  The
transaction will be preceded by a $1.2 billion capital contribution to the new
Grace specialty chemicals company, which will use the cash to pay down
substantially all of its debt.

      Grace shareholders will receive approximately 40.9 million common shares
and 36 million new convertible preferred shares in the new Sealed Air.  The
convertible preferred shares will have a stated value of $1.8 billion, be
convertible into approximately 31.8 million common shares of the new Sealed
Air at a per share conversion price of $56.525 and will pay dividends at a
four percent annual rate.  On a fully diluted basis, Grace shareholders and
current Sealed Air shareholders will own 63 percent and 37 percent,
respectively, of the new Sealed Air.

      Based on Sealed Air's stock price at the close on August 13, the merger
has an estimated value to Grace and Grace shareholders of approximately $5
billion, including $1.9 billion of Sealed Air common stock, $1.8 billion face
amount of the convertible preferred shares and the $1.2 billion cash
contribution to Grace at the time of the merger.

      Excluding the effect of transaction and integration costs, the
transaction is expected to be accretive to Sealed Air's earnings per share
going forward.

      Albert J. Costello, chairman, president and chief executive officer of
Grace, will continue to be chairman, president and chief executive officer of
the new Grace specialty chemicals company, and T.J. Dermot Dunphy, chairman
and chief executive officer of Sealed Air, will be chairman and chief
executive officer of the new Sealed Air.

      Mr. Costello said, "This transaction provides Grace shareholders with an
immediate premium for Grace's packaging business, the opportunity to continue
to participate in the future value of an even stronger packaging company with
excellent growth prospects, and an ongoing stake in what will now be a highly
focused and strong specialty chemicals company.  It represents another
significant achievement in our ongoing mission to deliver substantial value to
Grace shareholders, both from operational improvements and creative
transactions."

THE NEW SEALED AIR

      Mr. Dunphy said, "The combination of Sealed Air and Grace Packaging will
create an outstanding protective and specialty packaging company that will
serve the needs of a broad range of customers throughout the world.  The
rationale behind the merger of these two packaging businesses, both leaders in
technological innovation and marketing effectiveness, is clearly evident."

      Mr. Dunphy continued, "The combined packaging company will have global
reach and will be well positioned to grow at above-average rates in the
rapidly changing global marketplace, to penetrate new geographic markets with
its full range of products, and to seek out additional strategic alliances
that will further strengthen its global position.  We expect that the
combined company will benefit from a broad range of operating synergies."

      On a pro forma basis, the new Sealed Air would have sales in excess of
$2.5 billion and, based on Sealed Air's current stock price, a total market
capitalization, including debt and preferred stock, of approximately $7
billion.

      The new Sealed Air will be headquartered in Saddle Brook, New Jersey.
In addition to Mr. Dunphy, other key executives will include William V.
Hickey, president and chief operating officer of Sealed Air, and J. Gary
Kaenzig, Jr., president of Grace Packaging.  All current officers of Sealed
Air as well as several executives of the current Grace packaging organization
will be officers of the new Sealed Air.

      The board of the new Sealed Air will consist of the seven current Sealed
Air directors as well as several non-management directors from the current
board of Grace, who will resign from the Grace board upon transaction
completion.

      Grace's packaging business, best known by the Cryovac (Registered)
brand, is the world's leader in packaging materials and systems to preserve
perishable foods.  Cryovac (Registered) provides value-added packaging
systems, including packaging materials, equipment, technical support and
graphical design, for a global customer base in the food, consumer goods and
industrial products industries.  Other product lines include Omicron
(Trademark) rigid plastic cups and tubs for dairy foods and Formpac
(Trademark) foam trays for supermarkets and institutional food service.

      Sealed Air is a global leader in protective and specialty packaging
materials and systems.  Sealed Air's wide range of protective and specialty
packaging materials and systems include Instapak (Registered) polyurethane
foam packaging systems, engineered polyethylene foams, Bubble Wrap
(Registered) air cellular cushioning materials, Cell-Aire (Registered)
polyethylene foam, a wide range of protective and durable mailers, including
mailers sold under the widely recognized "Jiffy" (Trademark) trademark, and
Dri-Loc (Registered) absorbent pads used for retail packaging of meat, fish
and poultry.

      Certain Cryovac (Registered) products, such as vacuum-sealed food
packaging, are used by customers in conjunction with Sealed Air products, such
as Dri-Loc (Registered) absorbent pads.

THE NEW GRACE SPECIALTY CHEMICALS COMPANY

      "I am enthusiastic about the future growth opportunities for the new
Grace specialty chemicals company," said Mr. Costello.  "Our new Grace
specialty chemicals company will be financially strong, and will continue to
build upon its market leadership, technological strengths, and global
presence.  At the same time, we will continue our aggressive cost reduction
and capital management efforts which have proven so successful over the past
few years, leading to consistent operating margin improvements.  Furthermore,
our new financial position will allow added flexibility to invest in new
product development, geographic expansion and strategic acquisitions."

      The new Grace specialty chemicals company will maintain its
headquarters in Boca Raton, Florida.  Grace Davison is the world's leading
supplier of fluid cracking catalysts, silica-based polyolefin catalysts and
silica gels.  Grace Construction Products is a leading global supplier of
specialty products to the construction industry, including concrete
additives, structural waterproofing and fireproofing products.  DAREX
Container Products is a leading supplier of container sealants and
coatings.

OTHER HIGHLIGHTS OF THE TRANSACTION

      The definitive agreement is subject to customary conditions, including
approval of both companies' shareholders and certain regulatory approvals.

      The historic liabilities of Grace, including asbestos and environmental
liabilities of the non-packaging business, will remain with the specialty
chemicals company.

      The shares of both the new Sealed Air and the new Grace specialty
chemicals company are expected to be listed on the New York Stock Exchange.
