         Item 5.   Other Events.


                   On August 14, 1997, W. R. Grace & Co. ("Grace") and

         Sealed Air Corporation ("Sealed Air") announced that they had

         entered into an Agreement and Plan of Merger, dated as of

         August 14, 1997 (the "Merger Agreement"), pursuant to which

         Grace's packaging business ("Packaging") would combine with

         Sealed Air (the "Merger") immediately following a spin-off of

         Grace's specialty chemicals businesses (the "Spin-off").  

                   In connection with the Spin-off and Merger, Grace

         will contribute its specialty chemicals businesses to a newly

         formed wholly owned subsidiary of Grace ("New Grace"), which

         will become a publicly traded company that will retain the name

         "W. R. Grace & Co."  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 (as defined below) and Packaging following the Merger. 

                   In the Merger, a wholly owned subsidiary of Grace

         will merge with and into Sealed Air to create a new publicly

         owned company, to be called "Sealed Air Corporation" ("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 approximately 40.9 million 

         shares of common stock, par value $.10 per share, of New Sealed 

         Air ("New Sealed Air Common Stock") 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

         immeditely after the Merger, former Grace shareholders will

         own, in the aggregate, approximately 63% of the equity of New

         Sealed Air and former Sealed Air shareholders will own the

         remaining 37%.

                   Grace and Sealed Air have issued a joint press

         release with respect to the foregoing, which is filed as an

         exhibit hereto.

                   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 corpora-
         tion ("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 "Dis-
         tribution").  

                   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 Agree-
         ment.

                   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 Incorpora-
         tion of Grace shall be amended (the "Newco Amendment") to
         change the name of Grace to "Sealed Air Corporation" (such cor-
         poration, from and after the Effective Time, is sometimes here-
         inafter referred to as "Newco") and to effect the other amend-
         ments 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 share-
         holders under the Code and the Merger shall qualify as a "reor-
         ganization" 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 inter-
         ests 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:

         ing Date."

         tion"), until duly amended in accordance with the terms thereof
         and the DGCL.  At the Effective Time, the Certificate of Incor-
         poration of Grace (the "Grace Certificate of Incorporation")

                   SECTION 2.2.  Surviving Corporation By-laws.  The By-

                   SECTION 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 out-
              standing 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 Convert-
              ible Preferred Share issued and outstanding immediately
              prior to the Effective Time shall remain issued and out-
              standing 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 out-
              standing 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 out-
              standing, 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.

                   SECTION 4.2.  Exchange of Old Certificates for New
         Certificates.  (a)  Appointment of Exchange Agent.  From and


                                       -4-
                                       

         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 Certifi-
         cates 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 share-
         holder with the provisions of Section 4.2(b), a book-entry ac-
         count 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 re-
         lating to the ownership of Newco Common Shares.

                   (b)  Exchange Procedures.  Promptly after the Effec-
         tive Time, Newco shall cause the Exchange Agent to mail or de-
         liver 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 par-
         ties hereto prior to the Effective Time) containing instruc-
         tions 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 accor-
         dance 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 is-
         sued in a name other than that in which the Old Sealed Air Cer-
         tificate surrendered in exchange therefor is registered, it
         shall be a condition of such exchange that the person request-
         ing such exchange shall pay any transfer or other taxes re-
         quired 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 un-
         claimed by the former shareholders of Sealed Air.  Any such
         former shareholders who have not theretofore exchanged their

         this Article IV who desires to do so shall thereafter be en-
         titled to look exclusively to Newco and only as general credi-
         tors 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 Certifi-
         cate 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 Certifi-
         cate, Newco shall, in exchange for such lost, stolen or de-
         stroyed Old Sealed Air Certificates, issue or cause to be is-
         sued the Newco Certificate deliverable in respect thereof pur-
         suant to this Article IV.  No party hereto, nor the Exchange
         Agent, shall be liable to any holder of former Sealed Air Com-
         mon 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 accor-
         dance 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 Ef-
         fective Time, shall be rights and obligations of Newco follow-
         ing the Effective Time and (ii) each unexercised right granted

         Share in accordance with the terms and conditions of the ap-
         plicable Sealed Air Stock Plans, as amended from time to time.

                          REPRESENTATIONS AND WARRANTIES

                   SECTION 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 Agree-
         ment (the "Grace Disclosure Letter"):

                   (a)  Capital Stock.  (i)  Grace.  The authorized cap-
              ital 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 trea-
              sury 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 re-
              served 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
                                       
                                       -7-
                                       
              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 securi-
              ties the holders of which have the right to vote (or are
              convertible or exchangeable into or exercisable for secu-
              rities 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 pur-
              suant to the terms of options, securities or plans re-
              ferred to above and except in connection with the Transac-
              tion Agreements, there are no shares of capital stock of
              Grace authorized, issued or outstanding and there are no
              preemptive rights or any outstanding subscriptions, op-
              tions, puts, calls, warrants, rights, convertible or ex-
              changeable securities or other agreements or commitments
              of Grace or any of its subsidiaries of any character re-
              lating to the issued or unissued capital stock or other
              securities of Grace or any of its subsidiaries (including,
              without limitation, the issuance, sale, purchase, redemp-
              tion, 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 Com-
              mon Stock").  As of the date of this Agreement, 1,000
              shares of Merger Sub Common Stock are issued and outstand-
              ing, 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 subsidiar-
              ies 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 Sur-
              viving Corporation will be duly authorized, validly is-
              sued, fully paid and nonassessable, and will be owned by

                                       
                                       -8-
                                       
              Grace, free and clear of all liens, pledges, security in-
              terests, 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 mate-
              rial 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 re-
              ceipt of the requisite approval of its shareholders neces-
              sary 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 requi-
              site corporate power and authority and has taken all cor-
              porate 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 trans-
              actions 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 ac-
              cordance 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 In-
              corporation) and the Distribution are the only votes of
              the holders of Grace's capital stock necessary in connec-
              tion 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 Securi-
              ties 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, registra-
              tions, approvals, permits or authorizations required to be
              obtained by it or any such subsidiary from, any govern-
              mental or regulatory authority, agency, court, commission
              or other entity, domestic or foreign ("Governmental Enti-
              ty"), in connection with the execution, delivery or per-
              formance 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 Agree-
              ment 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 ("Con-
              tracts") 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 li-
              cense to which it or any of its subsidiaries is subject,
              except, in the case of clause (B) above, for such breach-
              es, violations, defaults, accelerations or changes that
              are disclosed in the Grace Disclosure Letter or, individu-
              ally 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 Undis-
              closed Liabilities.  (i)  Grace has filed all forms, re-
              ports 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 subsid-
              iaries prior to the Effective Time, as amended or supple-
              mented, 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 con-
              tain 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 incor-
              porated by reference into its SEC Documents (including the
              related notes and schedules) fairly presents in all mate-
              rial 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 re-
              spects 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 other-
              wise, that, individually or in the aggregate, are reason-
              ably 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 busi-
              nesses only in the ordinary and usual course of such busi-
              nesses, and there has not been any change or development
              or combination of changes or developments (including any
              worsening of any condition currently existing) which, in-
              dividually or in the aggregate, is reasonably likely to
                                       
                                       -11-

              New Grace Group.

                   (g)  Takeover Statutes; Rights Plan.  The execution,
              delivery and performance of this Agreement and consumma-
              tion 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 Recapi-
              talization, and the Distribution and to terminate or re-
              deem the Grace Rights at or prior to the Effective Time.

              its subsidiaries or any of their respective officers, di-
              rectors 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 con-
              templated herein, except pursuant to arrangements dis-
              closed in writing to the other parties hereto prior to the
              date hereof.

              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 ag-
              gregate, are not reasonably likely to have a Material Ad-
              verse 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 re-
              quests 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

              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 litiga-

                                       -12-
                                       
              recorded as a liability on its balance sheet (in accor-
              dance with US GAAP); (v) neither Grace nor any of its sub-
              sidiaries is a party to any tax sharing or similar agree-
              ment 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 re-
              spects, 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 fur-
              nished by Grace to Sealed Air pursuant hereto or in con-
              nection 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 mis-
              leading.

                   SECTION 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 juris-
              diction, or, if not, duly qualified) as a foreign corpora-
              tion in each jurisdiction where the properties owned,
              leased or operated, or the business conducted, by Packco
              or such Packco Subsidiary require such qualification, ex-
              cept 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 Ad-
              verse Effect with respect to the Packco Group or the Pack-
              aging 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


                                       -13-
                                       
              corporate power and authority and will have taken all cor-
              porate action necessary in order to consummate the trans-
              actions contemplated hereby and by the other Transaction
              Agreements.  

                   (c)  Capitalization.  All issued and outstanding
              shares of capital stock of Packco and each Packco Subsid-
              iary (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 restric-
              tions 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, capi-
              tal 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, val-
              idly issued, fully paid and nonassessable.

              ties.  (i)  Included in the Packaging Business Disclosure

              Letter Financial Statements," and the balance sheet as of
              December 31, 1996 included therein, the "Packaging Busi-
              ness Disclosure Letter Balance Sheet").  The balance
              sheets included in the Packaging Business Disclosure

              Basis of Presentation) fairly present in all material
              respects, and the special purpose consolidated and com-
              bined balance sheet to be included in the Packaging Busi-
              ness Financial Statements (including any related notes and

                                       -14-
                                       
              the consolidated financial position of the Packaging Busi-
              ness, 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 shareholders' equity to be included in the Packaging
              Business Financial Statements (including any related notes
              and schedules) shall fairly present in all material re-
              spects, the consolidated results of operations, cash flows
              and retained earnings, as the case may be, of the Pack-
              aging 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 state-
              ments, to normal year-end adjustments).

                  (ii)  Except as disclosed on the Packaging Business
              Disclosure Letter Balance Sheet or in the Basis of Presen-
              tation thereto, the Packco Group does not have any li-
              abilities of any kind whatsoever, whether or not accrued,
              contingent or otherwise, that, individually or in the ag-
              gregate, 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 connec-
              tion with the Grace Credit Agreement).

                   (e)  Absence of Certain Events and Changes.  Except
              (i) as disclosed in the Packaging Business Disclosure Let-
              ter, and (ii) as contemplated by the Transaction Agree-
              ments, 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, in-
              dividually 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 subsidiar-
              ies (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 Busi-
              ness.  Grace and its subsidiaries (with respect to the
                                       
                                       -15-
                                       
              Packaging Business) have, and immediately after the Con-
              tribution 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 En-
              tities that are required in order to permit the Packco
              Group to carry on the Packaging Business as it is pres-
              ently conducted by Grace and its subsidiaries, except for
              such permits, licenses, certificates, orders, filings, ap-
              plications and registrations, the failure to have or make
              which, individually or in the aggregate, are not reason-
              ably 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 Distribu-
              tion Date and subject to the provisions of Article II of
              the Distribution Agreement or as disclosed in the Packag-
              ing 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 De-
                   cember 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 as-
                   sets 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 sub-
                   sidiaries as of the Distribution Date;

              in each case except for such matters as would not, indi-
              vidually or in the aggregate, have a Material Adverse Ef-
              fect 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 pro-
              ceedings pending or, to the knowledge of its executive
              officers, threatened, or investigations pending, against


                                       -16-

              Business, Packco or any Packco Subsidiary that, individu-
              ally 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 out-
              standing orders, writs, injunctions, decrees, stipulations
              or awards (whether rendered or issued by a court or Gov-
              ernmental Entity, or by arbitration) against Grace or its
              subsidiaries with respect to the Packaging Business, Pack-
              co 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.

              ments filed with the SEC prior to the date hereof and ex-
              cept for such matters that, individually or in the aggre-
              gate, 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

              and any such extension shall have been granted and not
              expired, and all such filed returns are complete and accu-
              rate in all material respects; (ii) all taxes shown as due
              and payable on returns filed with respect to the Packaging

              been paid in full or have been recorded as a liability on
              the Packaging Business Disclosure Letter Balance Sheet (in
              accordance with the Basis of Presentation set forth there-
              in); (v) neither Grace, Packco nor any Packco Subsidiary
              is a party to any tax sharing or similar agreement pursu-
              ant to which the Packaging Business has indemnified an-
              other party with respect to taxes; and (vi) neither Grace
              (with respect to the Packaging Business), Packco nor any
              of the Packco Subsidiaries has waived any applicable stat-
              ute 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 ag-
              gregate, are not reasonably likely to have a Material Ad-
              verse Effect with respect to the Packco Group or the Pack-

              the Packco 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

                   (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 aggre-
              gate, have a Material Adverse Effect with respect to the

              sidiaries to compete in any line of business or with any

                   (l)  Employee Benefit Plans.  (i)  The Packaging
              Business Disclosure Letter includes a complete list of all
              material employee benefit plans, programs, policies, prac-
              tices and other arrangements (regardless of whether they
              are funded or unfunded or foreign or domestic, but exclud-
              ing any such plans, programs, policies, practices and ar-
              rangements mandated or sponsored by a Governmental Entity
              with respect to foreign Packco Employees) providing bene-
              fits to any current or former Packco Employee or benefi-
              ciary or dependent thereof, sponsored or maintained by
              Grace or any of its subsidiaries, with respect to the
              Packaging Business, Packco or any of the Packco Subsidiar-
              ies, or to which Grace or any of its subsidiaries, with
              respect to the Packaging Business, Packco or any of the
              Packco Subsidiaries contributes or is obligated to con-
              tribute (the "Packaging Business Plans").  Without
              limiting the generality of the foregoing, the term
              "Packaging Business 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; 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 here-
              of.  The Packaging Business Disclosure Letter also spe-
              cifically identifies those Packaging Business Plans that
              are sponsored, maintained or contributed to exclusively by
              Packco or any of the Packco Subsidiaries exclusively for

                                       
                                       -19-
                                       
              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 re-
              spect 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 fol-
              lowing: (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 is-
              sued 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 identi-
              fies 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 is-
              sued a favorable determination letter with respect to each
              Packco Qualified Plan, in each case that has not been re-
              voked, or an application for such a letter has been or
              will be filed before the expiration of the remedial amend-
              ment 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 re-
              lated 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 compli-
              ance, in all material respects, with all provisions of
              ERISA, the Code and all other laws and regulations appli-
              cable to the Packaging Business-Only Plans.  There is not
              now, nor do any circumstances exist that could give rise

                                       
                                       -20-
                                       

              to, any requirement for the posting of security with re-
              spect to any Packaging Business-Only Plan or the imposi-
              tion of any lien on the assets of Packco or a Packco Sub-
              sidiary under ERISA or the Code.  No prohibited transac-
              tion (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) cor-
              responding or similar provisions of foreign laws or regu-
              lations, 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 sole-
              ly 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 pol-
              icies funding any Packaging Business Plan, have been time-
              ly 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 Agree-
              ment) have been timely made in accordance with past prac-
              tice.

                 (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 ag-
              gregate, 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 contem-
              plated 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 limit-
              ing 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


                                       -21-
                                       
              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 prod-
              uct licenses or registrations (including applications for
              any of the foregoing), technology, know-how, tangible or
              intangible proprietary intellectual property rights, in-
              formation or material (whether conceived, reduced to prac-
              tice or under development), formulae, inventions and new
              and investigational applications (including all options or
              other rights to acquire any of the foregoing) as are nec-
              essary, used or held for use in connection with the Pack-
              aging Business (the "Packaging Business Intellectual Prop-
              erty"), 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 Subsid-
              iaries, 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 aggre-
              gate, 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 pos-
              sessed by Grace and its Subsidiaries) all of the Packaging
              Business Intellectual Property.  Except as contemplated by


                                       -22-
                                       
              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.

                   SECTION 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 simul-
         taneously 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 out-
              standing as of such date.  157,858 Sealed Air Common
              Shares were held in treasury by Sealed Air and its subsid-
              iaries as of August 14, 1997.  As of August 14, 1997,
              there were outstanding under the Sealed Air Amended Con-
              tingent 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 ex-
              changeable 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 autho-
              rized and validly issued and is fully paid and nonassess-
              able and, except for an immaterial number of shares held
              by officers and directors of Sealed Air and its subsid-
              iaries 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

                                       
                                       -23-
                                       
              except for awards and Sealed Air Common Shares issued af-
              ter 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 autho-
              rized, issued or outstanding and there are no preemptive
              rights or any outstanding subscriptions, options, puts,
              calls, warrants, rights, convertible or exchangeable se-
              curities 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 issu-
              ance, 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 organiza-
              tion and is in good standing (if recognized in such juris-
              diction, or, if not, duly qualified) as a foreign corpo-
              ration 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 subsid-
              iaries 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 com-
              plete 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 re-
              ceipt of the requisite approval of its shareholders to
              consummate the Merger, Sealed Air has the requisite cor-
              porate 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 there-
              by, including, without limitation, the approval of the


                                       -24-
                                       
              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 de-
              livered shall be, a valid and binding agreement of Sealed
              Air enforceable in accordance with its terms.  The affir-
              mative 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 Merg-
              er.

                   (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 Securi-
              ties 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, regis-
              trations, approvals, permits or authorizations required to
              be obtained by it or any such subsidiary from, any Govern-
              mental 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, ex-
              cept 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 contem-
              plated 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 breach-
              es, violations, defaults, accelerations or changes that
              are disclosed in the Sealed Air Disclosure Letter or,


                                       -25-
                                       
              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 Undis-
              closed 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 re-
              quirements 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 mis-
              leading.  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 con-
              solidated statements of earnings, cash flows and share-
              holders' 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 share-
              holders' 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 busi-
              nesses only in the ordinary course of such businesses, and

                                       
                                       -26-
                                       
              there has not been any change or development or combina-
              tion 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, li-
              censes, 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 registra-
              tions, the failure to have or make which, individually or
              in the aggregate, are not reasonably likely to have a Ma-
              terial 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 Decem-
                   ber 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, indi-
              vidually or in the aggregate, have a Material Adverse Ef-
              fect on Sealed Air.
                                       
                                       -27-
                                       
                   (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 inves-
              tigations pending, against Sealed Air or any of its sub-
              sidiaries that, individually or in the aggregate, are rea-
              sonably likely to have a Material Adverse Effect with re-
              spect to Sealed Air.  There are no judgments or outstand-
              ing orders, writs, injunctions, decrees, stipulations or
              awards (whether rendered or issued by a court or Govern-
              mental 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 ag-
              gregate, are not reasonably likely to have a Material Ad-
              verse 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, de-
              ficiency, 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 com-
              pleted 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 mat-
              ters 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


                                       -28-
                                       
              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 Con-
              tract 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 with-
              out 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 Disclo-
              sure Letter includes a complete list of all material em-
              ployee 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 man-
              dated 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 con-
              tribute (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 Sec-
              tion 3(2) of ERISA.  

                  (ii)  With respect to each Sealed Air Plan providing
              benefits to U.S. Sealed Air Employees, Sealed Air has de-
              livered 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, cor-
              rect and complete copy of each of the following:  (A) all


                                       -29-
                                       
              plan documents, (B) all benefit schedules, trust agree-
              ments 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 ac-
              companying 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 let-
              ter 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 Qual-
              ified 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 oc-
              curred 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 main-
              tained by Sealed Air, any of its subsidiaries or any of
              their respective ERISA Affiliates is subject to Title IV
                                       
                                       -30-
                                       
              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, con-
              tributed to or been obligated to contribute to any Multi-
              employer Plan or Multiple Employer Plan.  There does not
              now exist, nor do any circumstances exist that could re-
              sult 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 Sec-
              tion 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 aggre-
              gate, 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 contem-
              plated 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 contem-
              plated 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 ex-
              cept for such matters that, individually and in the ag-
              gregate, are not reasonably likely to have a Material Ad-
              verse Effect with respect to Sealed Air, (i) Sealed Air
              and its subsidiaries are and have been in compliance with


                                       -31-
                                       
              all applicable Environmental Laws; (ii) Sealed Air and its
              subsidiaries hold and have held all permits under any En-
              vironmental Law required for the operation of their re-
              spective businesses as presently conducted and are in com-
              pliance 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 re-
              quests 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 as-
              serted 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 de-
              cree 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 "Na-
              tional Priorities List" under CERCLA, or any similar
              state, local or foreign list of sites requiring inves-
              tigation or cleanup.

                   (n)  Takeover Statutes; Rights Plans.  The execution,
              delivery and performance of this Agreement and consumma-
              tion 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, commis-
              sions or finders' fees in connection with the transactions
              contemplated herein, except pursuant to arrangements dis-
              closed 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
                                       
                                       -32-
                                       
              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 investiga-
              tional 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 rea-
              sonably 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 Prop-
              erty or is aware, to the knowledge of the executive offic-
              ers of Sealed Air and its subsidiaries, of any infringe-
              ment with respect thereto, and there is no infringement by
              Sealed Air or its subsidiaries of the intellectual prop-
              erty rights of others, which, in each case, would, indi-
              vidually 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 ad-
              equate 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 Intel-
              lectual Property.

                   (q)  Tax Matters.  At the Effective Time, the repre-
              sentations 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 ef-
              fect as if set forth herein in their entirety.

                   (r)  Disclosure.  The representations and warranties
              of Sealed Air contained in this Agreement or in any writ-
              ten 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 mis-
              leading.  
                                       
                                       -33-
                                       

                                    ARTICLE VI

                                    COVENANTS

                   SECTION 6.1.  Interim Operations.  Each of Grace and
         Sealed Air covenants and agrees as to itself and its subsid-
         iaries that, from and after the date hereof until the Effective
         Time, except insofar as the other parties shall otherwise con-
         sent 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 pre-
              serve their business organization intact and maintain
              their existing relations with customers, suppliers, em-
              ployees 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 docu-
              ment); (iii) split, combine or reclassify any outstanding
              capital stock; or (iv) declare, set aside or pay any divi-
              dend payable in stock or property with respect to any of
              its capital stock (other than, in the case of Grace, regu-
              lar quarterly cash dividends consistent with Grace's cur-
              rent practice, and intercompany dividends).  

                   (c)  Neither it nor any of its subsidiaries will is-
              sue, sell, pledge, dispose of or encumber, or authorize or
              propose the issuance, sale, pledge, disposition or en-
              cumbrance of, any shares of, or securities convertible or
              exchangeable for, or options, puts, warrants, calls, com-
              mitments 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 fore-
              going (A) Grace may grant options to acquire Grace Common
              Shares so long as such options will not, after the Recapi-
              talization, 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


                                       -34-
                                       
              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 dis-
              pose 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 Dis-
              closure 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, sever-
              ance 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 appli-
              cable law, and except in the ordinary and usual course of
              business, neither it nor any of its subsidiaries will es-
              tablish, adopt, enter into, make, amend or make any elec-
              tions under any collective bargaining, bonus, profit shar-
              ing, 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 account-
              ing 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 pro-
              pose 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 (includ-
              ing 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 man-
              agement 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 Pack-
              co 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 au-
              thorize or enter into an agreement to take any of the ac-
              tions referred to in paragraphs (a) through (k) above.

                   SECTION 6.2.  Certain Transactions.  

                   (a)  It is understood and agreed by the parties here-
         to that, pursuant to the Distribution Agreement, at the time of
         the Reorganization and subject to Section 2.02 of the Distribu-
         tion Agreement, neither Grace nor any member of the Packco
         Group shall have cash or marketable securities, it being con-
         templated 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 with-
         held.

                   SECTION 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 di-
         rect and use its best efforts to cause its employees, agents


                                       -36-
                                       
         and representatives (including, without limitation, any invest-
         ment banker, attorney or accountant retained by it or any of
         its subsidiaries) not to, initiate, solicit or encourage, di-
         rectly or indirectly, any inquiries or the making or implemen-
         tation of any proposal or offer with respect to a merger, ac-
         quisition, consolidation, business combination, recapitaliza-
         tion or similar transaction involving, or any purchase of all
         or any significant portion of the assets or any equity securi-
         ties of, it or any of its subsidiaries (any such proposal or
         offer being hereinafter referred to as an "Acquisition Pro-
         posal") 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 nego-
         tiations directly or through its representatives if (i) the
         failure to provide such information or participate in such ne-
         gotiations 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 pro-
         posal, the terms thereof and the availability of adequate fi-
         nancing 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 con-
         summated and represents a transaction more favorable to its
         shareholders than the Reorganization (a "Higher Offer"); pro-
         vided 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, dis-
         cussion or negotiations.

                                       
                                       -37-
                                       
                   SECTION 6.4.  Information Supplied.  Each of the par-
         ties 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 Regis-
         tration 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 supple-
         ment thereto is filed in definitive form with the SEC or mailed
         to shareholders and at the time of the applicable Meeting, con-
         tain 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 docu-
         ments 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 re-
         quirements of the Exchange Act.

                   SECTION 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 ac-
         tion 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 recom-
         mend 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, with-
         drawal, modification or change of recommendation or recommenda-
         tion 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


                                       -38-
                                       
         identity of the other party thereto and the material terms and
         conditions of the agreement to be entered into with such per-
         son), shall not constitute a breach of this Agreement by Grace
         or Sealed Air, as the case may be.

                   SECTION 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 Regis-
         tration Statement and the Joint Proxy Statement to be mailed to
         their shareholders, and Grace shall prepare the New Grace Reg-
         istration 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 con-
         sultation 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 transac-
         tions 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 applica-
         tions, notices, petitions, filings and other documents, and to
         obtain as promptly as reasonably practicable all necessary per-
         mits, consents, orders, approvals and authorizations of, or any
         exemption by, all third parties and Governmental Entities nec-
         essary 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 Govern-
         mental Entities necessary or advisable to consummate the trans-
         actions 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.  


                                       -39-
                                       
                   (c)  Each party hereto shall, upon reasonable request
         and except as otherwise may be required by applicable law, fur-
         nish 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 con-
         nection 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 writ-
         ten 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 contem-
         plated hereby.

                   (e)  Each party hereto shall cooperate with each oth-
         er 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 fa-
         vorable review of the proposed transaction under the HSR Act
         and any foreign antitrust or competition laws.

                   SECTION 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 quali-
         fication by Price Waterhouse LLP or other nationally recognized
         accounting firm reasonably acceptable to Sealed Air (the "Pack-
         aging Business Financial Statements").

                   (b)  Each of Grace and Sealed Air shall use all rea-
         sonable efforts to cause to be delivered to the other party, as
         appropriate, and its directors letters of its independent ac-
         countants, dated (i) the date on which each Registration State-
         ment 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" let-
         ters delivered by independent accountants in connection with
         registration statements.  

                   SECTION 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

                                       
                                       -40-
                                       
         access, during normal business hours throughout the period un-
         til 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 mod-
         ify 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 pro-
         vision 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 ob-
         tained 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 writ-
         ten confidentiality arrangements existing among the parties
         hereto.

                   SECTION 6.9.  Notification of Certain Matters.  Each
         party shall give 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 re-
         sult in any Material Adverse Effect or to delay, in any sub-
         stantial respect, or prevent consummation of the Reorganiza-
         tion, in each case to the knowledge of the executive officers.

                   SECTION 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, state-
         ment 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.

                   SECTION 6.11.  Employee Benefits; Headquarters Em-
         ployees.  (a)  Grace and Sealed Air covenant and agree that


                                       -41-
                                       
         from and after the Effective Time, Grace, Packco and the Sur-
         viving Corporation, as the case may be, shall maintain either
         employee benefits plans and programs that are, in the aggre-
         gate, at least substantially comparable to the plans and pro-
         grams in effect with respect to Packco Employees at the Ef-
         fective 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 acknowl-
         edges 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 manage-
         ment, investor relations, information systems and internal au-
         dit.  In seeking to fill these needs, Sealed Air shall work
         with Grace to identify, prior to the Effective Time, appropri-
         ate people located at Grace's Boca Raton headquarters and shall
         give such individuals preferential consideration.

                   SECTION 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 print-
         ing and mailing the Joint Proxy Statement and the Grace Regis-
         tration 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 lim-
         itation 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);

                        (B)  Section 8.2(ii) if, after an Acquisition
                   Proposal with respect to Grace has been publicly dis-

         stantial authority," as defined in Section 6662 of the Code, to
         support such a position.

              by any party hereto or any of its respective subsidiaries
              with, and all consents, approvals and authorizations re-
              quired 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, de-
              livery 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 ob-
              tained, 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.

              the Other Agreements and the consummation of the transac-
              tions contemplated hereby and thereby shall have been ob-
              tained and shall be in full force and effect, except for
              those the failure of which to obtain would not have a Ma-
              terial Adverse Effect with respect to (i) the New Grace
              Group (with respect to the condition for Grace), or (ii)

              judgment, decree, injunction or other order (whether tem-
              porary, preliminary or permanent) which is in effect and
              prohibits consummation of the transactions contemplated
              hereby or by the Distribution Agreement or the Other
              Agreements.

              fied or, to the reasonable satisfaction of Sealed Air,

         thereof ordinary voting power to elect at least a majority of
         the board of directors or others performing similar functions
         with respect to such corporation or other organization is di-
         rectly or indirectly owned or controlled by such party or by

         effect to its or their rights under this Agreement, in addition

         ties agree that the remedies at law for any breach or threat-
         ened breach, including monetary damages, are inadequate compen-
         sation for any loss and that any defense in any action for spe-

         hereof, or the application of such provision to persons or cir-
         cumstances other than those as to which it has been held in-
         valid or unenforceable, shall remain in full force and effect
                                       
                                       -53-
                                       
         and shall in no way be affected, impaired or invalidated there-
         by, so long as the economic or legal substance of the transac-
         tions contemplated hereby is not affected in any manner adverse
         to any party.  

                   SECTION 9.12.  Third-Party Beneficiaries.  Nothing
         contained in this Agreement, expressed or implied, is intended
         to confer upon any person or entity, other than the parties
         hereto, any benefit, right or remedies.

                   SECTION 9.13.  Further Assurances.  In addition to
         the actions specifically provided for elsewhere in this Agree-
         ment, but subject to Section 9.1 hereof, each of the parties

         taken, all actions, and to do, or cause to be done, all things
         reasonably necessary, proper or advisable under applicable
         laws, regulations and agreements to consummate and make effec-
         tive the transactions contemplated by this Agreement.

                   IN WITNESS WHEREOF, this Agreement has been duly ex-
         ecuted and delivered by the duly authorized officers of the

                     This DISTRIBUTION AGREEMENT (this "Agreement"),
         dated as of [         ], 1997, by and among W. R. Grace &
         Co., a Delaware corporation ("Grace"), W. R. Grace & Co.-

                                    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 Ef-
         fective 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:

              with FAS 87 ("ABO"), for (i) benefits of Packco Partici-
              pants (as defined in the Benefits Agreement) under the
              Union Retirement Plan and (ii) benefits of Packco Partici-
              pants under the Hourly Non-Union Retirement Plan (as de-
              fined in the Benefits Agreement) that are assumed by the
              Packco Hourly Non-Union Retirement Plan pursuant to Sec-
              tion 4.01(d) of the Benefits Agreement.  "Foreign Benefit
              Plan Liabilities" means the greater of (i) the sum of the


                                      - 7 -
                                   
              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 For-
              eign Pension Plan that are, pursuant to the Foreign Bene-
              fits 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 Distribu-
         tion Date based upon the actuarial and other assumptions used
         by AON to determine the ABO or PBO (as applicable) of the rel-
         evant Transferring New Grace Foreign Plan or Retained Grace
         Foreign Plan for purposes of Grace's fiscal 1996 year-end fi-
         nancial 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 appli-
         cable 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 lo-
         cal 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 neces-
         sary to reflect the Net Benefit Amount as so finally deter-
         mined.  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


                                      - 8 -
                                   
         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.

                                  dividend date for the Distribution
                                  (the "SAC Stock Price")

                                  cise price for the Newco Options, cal-
                                  culated as provided in the Benefits

         by dividing 36,000,000 by the aggregate number of shares of
         Grace Common Stock outstanding as of the Record Date, the re-
         sult 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).

         tween the Record Date and the Effective Time, including pursu-
         ant to the exercise of stock options granted by Grace (but not
         including issuances in the Recapitalization), such Consider-
         ation shall be appropriately adjusted.

               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 Sub-
         sidiary 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 trans-
         fers 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 As-
         sets, subject to Sections 2.05 and 2.10.

                   (b)  Effective as of the Distribution Date and sub-
         ject 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 obli-
         gated to make significant expenditures to effect such separa-
         tion prior to the Distribution Date.  Actions taken and expen-
         ditures 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 alloca-
         tion 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, cur-
         rent and future costs (and losses of tax or other economic ben-
         efits) of the respective Businesses.  With respect to any Asset
         that cannot reasonably be separated or otherwise allocated as


                                      - 18 -
                                   

         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 predomi-
         nantly 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 sep-
         arated 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 in-
         tellectual 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 prop-
         erty 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, includ-
         ing, 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 Busi-
         ness" 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 con-
         tainers 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 reason-
         able 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


                                      - 19 -

                                   
         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 un-
         duly 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) at-
         tributable 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. As-
         sets and Grace-Conn. Liabilities, on the other hand, that are
         located in jurisdictions outside the United States.  Such sepa-
         ration 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 For-
         eign Transfer that occurs after the Distribution shall be ef-
         fected 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 al-
         locable to such other party pursuant to Section 8.04.  Such
         payment shall, for Tax purposes, be characterized as an adjust-
         ment 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 subdivi-
         sion 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 relat-
         ing 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 lo-
         cal 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 immedi-
         ately following the Distribution ("Withholding Taxes") and (II)
         Taxes that would be imposed by the United States or any politi-
         cal subdivision thereof on a Deemed Repatriation (without tak-
         ing 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 Repa-
         triation ("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, how-
         ever, 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 


                                      - 21 -
                                   
         and Excess Short-Term Payables) and cooperate in good faith to
         minimize the amount of Subsidiary Excess Cash, taking into ac-
         count 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 in-
         come tax purposes of any other Foreign Packco Subsidiary, at-
         tributable 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 Ben-
         efit), calculated without regard to any Tax Item arising on the
         Foreign Transfer involving such Subsidiary,  that does not ex-
         ceed the amount of income or gain arising, for purposes of the
         applicable foreign income tax, on the Foreign Transfer involv-
         ing such Subsidiary.

                   (d)  In connection with the Foreign Transfers, cer-
         tain 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 fail-
         ure 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 Ad-
         justed Foreign Transfer Taxes borne by the other Group.  Grace
         agrees to indemnify and hold the Grace-Conn. Indemnitees harm-
         less, 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 recal-
         culated 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 


                                      - 22 -

                                   
         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 recal-
         culated, 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 in-
         corporation and by-laws of Packco shall be substantially simi-
         lar 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 Dis-
         tribution Date, the parties hereto shall take all steps neces-
         sary 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 Distribu-
         tion Date, enter into, or cause the appropriate members of the
         Group of which it is a member to enter into, the Other Agree-
         ments in connection with the Distribution, including, without
         limitation, agreements with respect to (i) insurance proce-
         dures, (ii) interim services (including, without limitation,
         services to be provided by the Shared Regional Headquarters
         consistent with current operations of the respective Busi-
         nesses, and services to be provided by country organizations to
         operations of the other Business consistent with past prac-
         tice), which shall be charged at allocated cost based on
         Grace's historical methodology, subject to applicable tax laws 


                                      - 23 -
                                    
         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 ser-
         vices) 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 pro-
         viding 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 ex-
         tensive 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 con-
         ditions 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, se-
         curity and other matters).  The parties shall enter into ap-
         propriate 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 in-
         cluded in the Other Agreements.

                   SECTION 2.06  FINANCING.  (a)  Prior to the Distri-
         bution 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 Capi-
         tal Contribution may be contributed to foreign Subsidiaries of
         New Grace.  It is contemplated that the New Grace Capital Con-
         tribution 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 
                                    

                                      - 24 -
                                    
         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 con-
         summate a cash tender offer in accordance with applicable secu-
         rities laws for any and all Grace-Conn. Public Debt.  Grace-
         Conn. may also elect, in its discretion, to defease or other-
         wise 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 insti-
         tutions 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 re-
         spect 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 sepa-
         rate in an interest-bearing escrow account with a financial
         institution and pursuant to escrow arrangements reasonably ac-
         ceptable 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 


                                      - 25 -
                                    
         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 ten-
         der offer that are, in the aggregate, in excess of the out-
         standing 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. Pub-
         lic Debt acquired, defeased or retired; and plus (iii) the
         costs of the letter of credit described above.

                   SECTION 2.07  GRACE RECAPITALIZATION.  (a)  Imme-
         diately 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 Recapitaliza-
         tion 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 ac-
         tions to effect the Recapitalization, including customary pro-
         cedures 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 Re-
         capitalization.  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 pro-
         portionate 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 


                                      - 26 -
                                    
         this paragraph.  As soon as practicable following the Distribu-
         tion Date, the Exchange Agent shall determine the excess of (i)
         the number of full shares of Newco Common Stock or Newco Con-
         vertible 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 Ex-
         cess Shares at the prevailing prices on the open market.  The
         sale of the Excess Shares by the Exchange Agent shall be ex-
         ecuted 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 compensa-
         tion 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 un-
         der 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 regis-
         tration 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 Em-
         ployee Benefits Agreement requiring registration under the Se-
         curities Act.

                   SECTION 2.09  GRACE AND NEW GRACE BOARDS.  The par-
         ties 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 indepen-
         dent 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.  Noth-
         ing herein shall be deemed to require the transfer of any As-
         sets 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 Subsid-
         iaries shall cooperate to obtain any necessary consents or ap-
         provals for the transfer of all Assets and Liabilities con-
         templated 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 Distribu-
         tion 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 enti-
         tled 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 Distri-
         bution 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 there-
         to, and shall be deemed to have assumed in accordance with the 


                                      - 28 -
                                    
         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 mem-
         bers 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 prac-
         tices (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 Sec-
         tion 8.01(a), the Board of Directors of Grace, in its sole dis-
         cretion and consistent with the Merger Agreement, shall estab-
         lish the Record Date and the Distribution Date and any appro-
         priate 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 Distri-
         bution 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 cer-
         tificates 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 

                                     - 29 -
                                    
         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 Agree-
         ment shall survive the Distribution Date.

                   SECTION 4.02  INDEMNIFICATION.  (a)  Except as spe-
         cifically otherwise provided in the Other Agreements, the New
         Grace Group shall indemnify, defend and hold harmless the Pack-
         co 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. Lia-
         bilities (including, without limitation, all Liabilities spe-
         cifically 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 infor-
         mation 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 


                                      - 30 -
                                     
         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 Indem-
         nifiable Losses arising out of or based upon any untrue state-
         ment or alleged untrue statement of a material fact, or omis-
         sion 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 (in-
         cluding the pro forma financial information relating to Newco
         contained in the Registration Statements (other than the his-
         torical information relating to Grace and the Packaging Busi-
         ness)), or necessary to make the statements therein not mis-
         leading.  

                   (c)  If any Indemnity Payment required to be made
         hereunder or under any Other Agreement is denominated in a cur-
         rency 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 de-
         termined 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 be-
         tween 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 other-
         wise 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 oth-
         er 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 In-
         demnitee 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 


                                      - 31 -
                                     
         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 In-
         demnitee and to Grace, if New Grace is the Indemnifying Party,
         or to the Indemnitee and New Grace, if Grace is the Indemnify-
         ing 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 con-
         sent, 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 Indemni-
         tee, 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 In-
         demnitees 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 rem-
         edy; and subject to the Indemnifying Party's control rights, as
         specified herein, the Indemnitees may participate in such in-
         vestigation 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 here-
         under.

                   (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 Par-
         ty which make it inappropriate for the Indemnifying Party to
         undertake the defense or settlement thereof, then such Indemni-
         fying Party shall not be entitled to undertake the defense or
         settlement of such Third-Party Claim; and counsel for the In-
         demnifying Party shall be entitled to conduct the defense of 


                                      - 32 -
                                     
         such Indemnifying Party and counsel for the Indemnitee (se-
         lected by the Indemnitee) shall be entitled to conduct the de-
         fense 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 sub-
         stantially 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 avail-
         able to it.

                   (d)  In no event shall an Indemnifying Party be li-
         able for the fees and expenses of more than one counsel for all
         Indemnitees (in addition to its own counsel, if any) in connec-
         tion with any one action, or separate but similar or related
         actions, in the same jurisdiction arising out of the same gen-
         eral 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 set-
         tlement thereof, subject to the terms and conditions of a mutu-
         ally 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 pro-
         vided in this Article IV shall be cumulative and shall not pre-
         clude 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.

                           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 coop-
         erate 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 here-
         to shall cause the appropriate members of its Group to prepare
         and file with the appropriate licensing and permitting authori-
         ties applications for the transfer or issuance, as may be nec-
         essary or advisable in connection with the transactions contem-
         plated 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 coop-
         erate and use all reasonable efforts to secure the transfer or
         issuance of the licenses and permits.

                   SECTION 5.03  INTERCOMPANY AGREEMENTS.  All con-
         tracts, licenses, agreements, commitments or other arrange-
         ments, 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, finan-
         cial, accounting, data processing, insurance or technical sup-
         port), 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 ei-
         ther 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 


                                      - 34 -
                                     
         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 Dis-
         tribution 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, contract or other obligation for which any
         member of the New Grace Group is or may be liable unless all
         obligations of the New Grace Group with respect thereto are
         thereupon terminated by documentation reasonably satisfactory
         in form and substance to the Chief Financial Officer, Treasurer
         or any Assistant Treasurer of New Grace, provided that the lim-
         itations in clause (ii) shall not apply in the event that a

         not apply in the event that a member of the New Grace Group
         obtains a letter of credit from a financial institution rea-
         sonably 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 specifically provided for elsewhere in this Agreement,
         each of the parties hereto shall use reasonable efforts to
         take, or cause to be taken, all actions, and to do, or cause to
         be done, all things reasonably necessary, proper or advisable
         under applicable laws, regulations and agreements to consummate
         and make effective the transactions contemplated by this Agree-
         ment.  Without limiting the foregoing, each party hereto shall
         cooperate with the other party, and execute and deliver, or use
         reasonable efforts to cause to be executed and delivered, all
         instruments, and to make all filings with, and to obtain all
         consents, approvals or authorizations of, any governmental or
         regulatory authority or any other Person under any permit, li-
         cense, agreement, indenture or other instrument, and take all
         such other actions as such party may reasonably be requested to
         take by any other party hereto from time to time, consistent
         with the terms of this Agreement, the Merger Agreement and the
         Other Agreements, in order to effectuate the provisions and
         purposes of this Agreement.  

                   SECTION 5.06  ENVIRONMENTAL CLAIMS COOPERATION.  With
         respect to claims relating to Environmental Laws described in
         clause (a) of the definition of Packco Liabilities, the New
         Grace Group and the Packco Group shall cooperate to minimize
         the costs incurred in connection with such claims and shall
         generally cooperate and provide appropriate information to the
         other party with respect to such claims.  Notwithstanding any
         other provision of this Agreement, including Article IV, Grace
         shall be entitled to participate in the defense of any such
         claims but New Grace shall control the resolution of any such
         claims; provided that New Grace shall not consent to entry of
         any judgment or enter into any settlement without the approval
         of Grace, which approval shall not be unreasonably withheld.


                                    ARTICLE VI

                              ACCESS TO INFORMATION

                   SECTION 6.01  PROVISION OF CORPORATE RECORDS.  Prior
         to or as promptly as practicable after the Distribution Date,
         Grace shall retain complete and accurate copies but shall de-
         liver to New Grace all corporate books and records of the New
         Grace Group in its possession and copies of the relevant por-
         tions of all corporate books and records of the Packco Group 


                                      - 36 -
                                     
         relating directly and predominantly to the Grace-Conn. Assets,
         the New Grace Business, or the Liabilities of the New Grace
         Group, including, in each case, all active agreements, active
         litigation files and government filings.  Grace shall also re-
         tain complete and accurate copies but deliver to New Grace all
         corporate board and committee minute books of Grace.  From and
         after the Distribution Date, all such books, records and copies
         shall be the property of New Grace.  Prior to or as promptly as
         practicable after the Distribution Date, New Grace shall de-

         Business, or the Liabilities of the Packco Group, including, in
         each case, all active agreements, active litigation files and
         government filings.  From and after the Distribution 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 reim-
         bursement of costs incurred by the providing party) by the re-
         questing 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 ac-
         cess 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 Informa-
              tion 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 


                                      - 37 -
                                     
              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 in-
              tend 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 mem-
              ber, not to disclose or otherwise waive any privilege at-
              taching 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 connec-
              tion 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; pro-
              vided, however, that Grace and New Grace may make such
              disclosure or waiver with respect to Privileged Informa-
              tion 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 con-
              cerning the reasonableness of withholding such consent, no
              disclosure shall be made prior to a resolution of such
              disagreement by a court of competent jurisdiction, pro-
              vided that the limitations in this sentence shall not ap-
              ply in the case of disclosure required by law and so cer-
              tified as provided in the first sentence of this para-
              graph.  

                   (c)  Upon any member of the Packco Group or any mem-
              ber of the New Grace Group receiving any subpoena or other
              compulsory disclosure notice from a court, other govern-
              mental agency or otherwise which requests disclosure of
              Privileged Information, in each case relating to pre-Dis-
              tribution business of the New Grace Group or the Packco
              Group, respectively, or relating to or arising in connec-
              tion 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 


                                      - 38 -
                                     
              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 de-
              fenses and claims of privilege have been finally deter-
              mined.  

                   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 wit-
         nesses to the extent that any such Person may reasonably be
         required in connection with any Litigation Matters, adminis-
         trative or other proceedings in which the requesting party may
         from time to time be involved and relating to the pre-Distri-
         bution 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 other-
         wise 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-Distri-
         bution 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, pri-
         or to the expiration of such period, any member of either par-
         ty's Group wishes to destroy or dispose of any such Information
         that is at least three years old, prior to destroying or dis-
         posing 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 dis-
         posed 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 In-
         formation to a location specified by, and at the expense of,
         the requesting party.


                                      - 39 -
                                     
                   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 Informa-
         tion 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 Per-
         son 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 sub-
         ject 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 mem-
         ber 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 govern-
         ment 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 in-
         clude, without limitation, promptly forwarding copies of appro-
         priate 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

         any documents or Information provided hereunder.

              amendment to the Grace Certificate of Incorporation and
              otherwise as required by applicable law and stock exchange

              provals required in connection with the transactions con-
              templated hereby shall have been received, except where
              the failure to obtain such consents or approvals would not
              have a material adverse effect on either (A) the ability
              of the parties to consummate the transactions contemplated
              by this Agreement, the Other Agreements or the Merger
              Agreement or (B) the business, assets, liabilities, finan-
              cial condition or results of operations of Grace-Conn. or
              Packco and their respective subsidiaries, taken as a
              whole;

                  (iv)  the transactions contemplated by Article II
              shall have been consummated in all material respects, to
              the extent required to be consummated prior to the Distri-

                   (v)  the shares of New Grace Common Stock to be is-

              Stock and the Newco Convertible Preferred Stock to be is-
              sued in the Recapitalization and the Merger, as the case
              may be, shall have been authorized for listing on the
              NYSE, in each case subject to official notice of issuance;

                  (vi)  the Board of Directors of New Grace, composed as

              ed;

              Act, as the case may be, by the SEC and no stop order sus-
              pending the effectiveness of either of the Registration
              Statements shall have been issued by the SEC and, to the
              knowledge of Grace and New Grace, no proceeding for that
              purpose shall have been instituted by the SEC;

                (viii)  the applicable parties shall have entered into
              each of the Other Agreements;

                  (ix)  (A) the Board of Directors of Grace shall have
              received customary opinions of a nationally recognized
              investment banking or appraisal firm in form and substance
              reasonably satisfactory to such Board to the effect that,
              after giving effect to the transactions set forth in Ar-
              ticle II hereof, neither Grace nor New Grace and Grace--
              Conn. will be insolvent (such opinions to be dated as of
              the date of the Merger Agreement, the date the Board of
              Directors of Grace declares the Distribution and the Dis-
              tribution Date) and (B) the financial condition of each of
              Grace and Grace-Conn. satisfies the requirements of Sec-
              tion 170 of the Delaware General Corporation Law and Sec-
              tion 33-687 of the Connecticut Business Corporation Act,
              respectively, such that the distribution of the common
              stock of Packco to Grace by Grace-Conn. and the Distribu-
              tion may be effected without violating such Sections, and
              the Board of Directors of Grace and the Board of Directors
              of Grace-Conn. shall in good faith have determined that
              such requirements have been satisfied; and 

                   (x)  the transactions contemplated hereby shall be in
              compliance with all applicable federal and state securi-
              ties laws.

                   (b)  Any determination made by the Board of Directors
         of Grace or Grace-Conn. on behalf of such party hereto prior to
         the Distribution Date concerning the satisfaction or waiver of
         any or all of the conditions set forth in this Section shall be
         conclusive.

                   SECTION 8.02  USE OF GRACE NAME AND MARK.  Grace ac-
         knowledges that Grace-Conn. shall own all rights in the "Grace"
         name and logo and related tradenames and marks.  Effective at
         the Distribution Date, Grace shall change its name to a name
         that does not use the word "Grace" or any variation thereof and
         shall itself, and shall cause each member of the Packco Group
         to, cease all use of the "Grace" name as part of any corporate
         name.  As promptly as practicable after the Distribution Date,
         Grace shall, and shall cause each member of the Packco Group 


                                      - 43 -
                                     
         to, cease all other use of the "Grace" name and logo and re-
         lated tradenames and marks, provided that Grace may use inven-
         tory including any such name, logo, tradenames or marks in ex-
         istence as of the Distribution Date.  Grace shall cause the
         Packco Group to use such names, logos and marks during such
         transition period only to the extent consistent with past prac-
         tice and as Grace reasonably believes is appropriate, and dur-
         ing the period of such usage Grace shall cause the Packco Group
         to maintain the same standards of quality with respect to such
         names, logos and marks as previously exercised.  No such mate-
         rial shall be used by the Packco Group after the six-month an-
         niversary of the Distribution Date.

                   SECTION 8.03  COMPLETE AGREEMENT.  This Agreement,
         the Exhibits and Schedules hereto and the agreements and other
         documents referred to herein shall constitute the entire agree-
         ment between the parties hereto with respect to the subject
         matter hereof (other than the Merger Agreement and the sched-
         ules and exhibits thereto) and shall supersede all previous
         negotiations, commitments and writings with respect to such
         subject matter.

                   SECTION 8.04  EXPENSES.  Except as otherwise specifi-
         cally provided herein or in any other Transaction Agreement,
         New Grace shall bear all costs and expenses (including all Debt
         Costs, Adjusted Foreign Transfer Taxes, Severance Costs and
         losses of benefits) incurred by Grace, New Grace and/or any
         members of their respective Groups (collectively, the "Transac-
         tion Costs") in connection with the transactions contemplated
         by this Agreement and the Other Agreements (including the Con-
         tribution (and the related transfers, separations and/or al-
         locations of Assets and Liabilities), the Intragroup Spinoff,
         the Distribution and the Recapitalization)); provided that
         Grace (for the account of Newco after the Merger) agrees to
         bear:  (i) the lesser of $50 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 all
         other Transaction Costs (excluding any Debt Costs, Adjusted
         Foreign Transfer Taxes, Severance Costs and costs and expenses
         payable by New Grace or Grace pursuant to Section 6.12 of the
         Merger Agreement) and (iii) the fees and costs incurred in con-
         nection with the Grace Credit Agreement.  "Severance Costs"
         means the costs associated with the termination in connection
         with the transactions contemplated hereby (including the Merg-
         er) of employment of employees of Grace and Grace-Conn. located
         at the Grace corporate headquarters.  To the extent Transaction
         Costs are not included in the New Grace Capital Contribution,
         Newco or New Grace shall promptly pay its share of any such
         costs upon receipt of reasonable documentation relating to such
         costs.  Appropriate payment shall be made between the parties 


                                      - 44 -
                                     
         in respect of Adjusted Foreign Transfer Taxes on the Distribu-
         tion Date so that Adjusted Foreign Transfer Taxes are borne in
         the proportions described above in this Section 8.04.  Ap-
         propriate payment shall be made between the parties in respect
         of Adjusted Foreign Transfer Taxes and the amount calculated
         pursuant to clause (c) of the definition of "New Grace Capital
         Contribution" to the extent that such amounts estimated as of
         the Distribution Date may be recalculated in a more accurate
         manner.  New Grace agrees that it shall pay, or cause Grace-
         Conn. to pay, all amounts payable by New Grace pursuant to Sec-
         tion 6.12(a) of the Merger Agreement.  Any amount paid by one
         party to the other under this Agreement in respect of Transac-
         tion Costs shall be treated, for tax purposes, as an adjustment
         to the portion of the New Grace Capital Contribution contrib-
         uted from Grace to New Grace.

                   SECTION 8.05  GOVERNING LAW.  This Agreement shall be
         governed by and construed in accordance with the laws of the
         State of Delaware (other than the laws regarding choice of laws
         and conflicts 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.

                   SECTION 8.07  AMENDMENT AND MODIFICATION.  This
         Agreement may be amended, modified or supplemented only by a
         written agreement signed by all of the parties hereto and sub-

         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 parties.  Except for the

         ment is solely for the benefit of the parties hereto and their

         Section headings contained in this Agreement are solely for the

         ties hereto and shall not in any way affect the meaning or in-
         terpretation of this Agreement.

                  (b)  The parties hereto intend that the Distribution
         shall be a distribution pursuant to the provisions of Section
         355 of the Code, so that no gain or loss shall be recognized
         for federal income tax purposes as a result of such transac-
         tion, and all provisions of this Agreement shall be so inter-
         preted.  The parties hereto do not intend to submit the Distri-
         bution to the Internal Revenue Service for a private letter
         ruling with respect to such nonrecognition, and any ultimate
         ruling or decision that any gain or loss should be recognized
         for federal income tax purposes shall not permit a rescission
         or reformation of this Agreement or transactions contemplated
         hereby.

                   SECTION 8.11  SEVERABILITY.  If any provision of this
         Agreement or the application thereof to any person or circum-
         stance is determined by a court of competent jurisdiction to be
         invalid, void or unenforceable, the remaining provisions here-
         of, or the application of such provision to persons or circum-
         stances 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 "Article," "Exhibit," "Schedule" or "Section," without
         more, are to Articles, Exhibits, Schedules and Sections to or

                   SECTION 8.13  TERMINATION.  Notwithstanding any pro-
         vision hereof, following termination of the Merger Agreement,
         this Agreement may be terminated and the Distribution abandoned

         Other Agreement shall have any Liability to any Person by rea-

         cated between the New Grace Group and the Packco Group in ac-
         cordance 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 Sub-
         sidiaries 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

         extent possible, takes into account the Employees' expertise,
         experience and existing positions and duties and does not un-
         reasonably 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 re-
         spective 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

         efit Plan, contract, agreement, statute, regulation  or other

         pay, or similar benefits in connection with actual or construc-
         tive termination or alleged actual or constructive termination

         limiting the generality of the foregoing, none of the transac-
         tions 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 ap-
         propriate 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

         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 transac-
         tions contemplated by the Distribution Agreement, shall be con-
         sidered 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 Dis-
         tribution Agreement, effective as of the Distribution Date, the
         Packco Group shall assume or retain, as appropriate, all Li-
         abilities relating to or arising out of claims made by or on
         behalf of Packco Participants for, or with respect to, Termina-
         tion Benefits relating to the actual or constructive termina-
         tion or alleged actual or constructive termination of employ-
         ment of any Packco Employee with any member of the Packco Group
         or the New Grace Group, whether before (in the case of con-
         structive termination), on or after the Distribution Date.

                                 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 Li-
         abilities 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 there-
         under and such other changes as New Grace shall, in its sole
         discretion, determine.  As soon as practicable after and effec-
         tive 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.
                                       
                                       -9-
                                       
                   (b)  Each such Grace Option that is held by a New
         Grace Employee or a Terminated Grace Participant shall be re-
         placed with an option (a "New Grace Option") to acquire a num-
         ber of New Grace Common Shares that equals the number of shares
         subject to such Grace Option immediately before such replace-
         ment, 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 be-
         fore 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 employ-
         ment by or termination of employment with Grace and its affili-
         ates shall be changed to references to employment by or termi-
         nation of employment with New Grace and its affiliates.  Effec-
         tive 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 adjust-
         ment, 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 near-
         est whole cent).  Each Grace Option as so adjusted shall other-
         wise have the same terms and conditions as were in effect be-
         fore 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 Dis-
         tribution Date, the New Grace Group shall assume all Liabili-
         ties 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.  How-
         ever, if the Distribution Date occurs later than March 31,
         1998, then Grace and New Grace shall use reasonable best ef-
         forts 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
                                       
                                      -10-
                                       
         the relative portions of the 1998 calendar year that precede
         and follow the Distribution Date.

                            PENSION AND SAVINGS PLANS

                   SECTION 4.01  Retirement Plans and Supplemental Re-
         tirement 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 Re-
         tirement 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 fidu-
         ciaries, trustees, custodians, recordkeepers and other fiducia-
         ries and service providers to the Salaried Retirement Plan, the
         SERP and the Hourly Non-Union Retirement Plan, and the appoint-
         ment or reappointment by Grace of all named fiduciaries, trust-
         ees, custodians, recordkeepers and other fiduciaries and ser-
         vice providers to the Union Retirement Plan. 

                   (b)  Effective as of the Distribution Date, the
         Packco Employees shall cease accruing benefits under the Sala-
         ried Retirement Plan, the SERP and the Hourly Non-Union Retire-
         ment Plan.  As promptly as practicable following the Distribu-
         tion Date, and effective as of the Distribution Date, Grace in-
         tends to implement a program for Packco Employees who partici-
         pated in the Salaried Retirement Plan before the Distribution
         Date designed to substantially make up for any anticipated ma-
         terial 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 em-
         ployee 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, ef-
         fective immediately before the Distribution Date: (A) the ac-
         crued 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
                                       
                                      -11-
                                       
         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 ap-
         plicable) 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 Li-
         abilities 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 desig-
         nate a defined benefit pension plan (the "Packco Hourly Non-
         Union Retirement Plan") to provide benefits and assume liabil-
         ities 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 Sec-
         tion 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 accept-
         able 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 Re-
         tirement Plan the amount described in Section 4.01(d)(iii) be-
         low.  Such transfer shall be in cash unless otherwise agreed by
                                       
                                      -12-
                                       
         Grace and New Grace.  As of the date of such transfer, and ef-
         fective 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 Re-
         tirement Plan during such period.  All of the foregoing calcu-
         lations 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 pro-
         cess of performing them.  Notwithstanding the foregoing, how-
         ever, 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 reg-
         ulations 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 Retire-
         ment Plan, to cause distributions in respect of Packco Par-
         ticipants 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 spon-
         sors of the Hourly SIP and the Salaried SIP; and (ii) one or
                                       
                                      -13-
                                       
         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 fiducia-
         ries, 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 fi-
         duciaries, trustees, custodians, recordkeepers and other fidu-
         ciaries and service providers to the Cypress 401(k) Plans and
         the Schurpack 401(k) Plan.

                   (b)  Each of the transfers provided for in this Sec-
         tion 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 practi-
         cable 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 Par-
         ticipants.  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 prac-
         ticable, the investment elections of participants as in effect
         immediately before the transfer, unless the parties agree oth-
         erwise.

                       (ii)  Grace, New Grace and Grace-Conn. shall co-
         operate in making all appropriate filings required under the
         Code or ERISA, and the regulations thereunder and any applica-
         ble securities laws, implementing all appropriate communica-
         tions with participants, maintaining and transferring appro-
         priate 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
                                       
                                      -14-
                                       
         Packco Savings Plan is qualified under Section 401(a) of the
         Code and the related trust is exempt from taxation under Sec-
         tion 501(a) of the Code, and (B) the receipt by Grace of a fa-
         vorable 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 taxa-
         tion 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 com-
         pletion 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 Partici-
         pants relating to or arising under the Hourly SIP and the Sala-
         ried 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 thereun-
         der to Packco Participants, that are not assumed by the Packco
         Group and the relevant Packco Savings Plan pursuant to the pre-
         ceding 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 ap-
         plicable.  The Packco Group shall be responsible for all Li-
         abilities 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 Rev-
         enue Service's Voluntary Compliance Resolution program or simi-
         lar 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 Li-
         abilities 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

         and administrative expenses).

                   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 Distribu-
         tion 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 Liabil-
         ities 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 spe-
         cifically provided in Section 5.02.  

                   SECTION 5.02  Retiree Welfare Benefits.  Effective as

         surance 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 Par-
         ticipants who would have been eligible to receive such benefits
         if they had retired at any time on or before the first anniver-
         sary 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 Par-
         ticipants 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
                                       
                                      -16-
                                       
         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 main-
         tain 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 ben-
         efits as outlined in Exhibit A hereto.  

                   SECTION 5.04  Split Dollar Plan; Deferred Compensa-
         tion Plan; Salary Protection Plan.  Effective as of the Distri-
         bution Date, each Packco Employee who participates in the Split
         Dollar Plan, the Deferred Compensation Plan or the Salary Pro-
         tection 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.

         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 reap-
         pointment 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 fiducia-
         ries, trustees, custodians, recordkeepers and other fiduciaries
                                       
                                      -17-
                                       
         and service providers to such Plan, to the extent such appoint-
         ments or reappointments are necessary.  No employer contribu-
         tions to such Plan shall be made or promised with respect to
         the 1998 plan year unless the parties otherwise agree.

                                  NON-U.S. PLANS

                   SECTION 6.01  Non-U.S. Plans Generally.  As soon as
         practicable after the date of this Agreement, the parties here-
         to shall enter into one or more agreements or memoranda of un-
         derstanding (collectively, the "Foreign Plans Agreement") re-
         garding the treatment and allocation of Liabilities relating to
         or arising under Benefit Plans (the "Foreign Plans") for Em-
         ployees 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 in-
         tended to be maintained by the Packco Group, after the Distri-
         bution Date; provided, that the insurance contracts funding
         each Insured Foreign Pension Plan (and any assets related
         thereto) shall be divided between the appropriate Packco Ben-
         efit Plan and New Grace Benefit Plan by the insurer in accor-
         dance with applicable law, regulation and practice.  Any trans-
         fers of assets or liabilities from a Noninsured Foreign Pension
         Plan shall be made on the basis of reasonable methods and as-
         sumptions 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 ac-
         cordance 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 determina-
         tions of the Local Actuary for accuracy.  It is the intention
         of the parties hereto that the Packco Group will assume or re-
         tain 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
                                       
                                      -18-
                                       
         Plans Agreement shall equal the Projected Benefit Obligation,
         calculated in accordance with FAS 87, for the liabilities as-
         sumed by Packco Benefit Plans pursuant to the Foreign Plans
         Agreement.

                                   ARTICLE VII

                                     GENERAL

                   SECTION 7.01  Preservation of Rights to Amend or Ter-
         minate Plans and to Terminate or Change Terms of Employment.
         No provision of this Agreement shall be construed as a limita-
         tion 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 provi-
         sion 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 oth-
         erwise have under the terms of the Benefit Plan itself.  Noth-
         ing contained in this Agreement shall confer upon any indi-
         vidual 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 fol-
         lowing the Distribution Date, except as provided in Section
         5.03 of this Agreement.

                   SECTION 7.02  Other Liabilities; Guarantee of Obliga-
         tions.  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 ben-
         efits made by or on behalf of any New Grace Participant, in-
         cluding salary, wages, bonuses, incentive compensation, sever-
         ance 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 re-
         tirement benefits, or other compensation under applicable law
         or otherwise, relating to or arising out of employment by Grace
                                       
                                      -19-
                                       
         or any of its subsidiaries before the Distribution Date or em-
         ployment by any member of the Packco Group on or after the Dis-
         tribution Date.  Notwithstanding the foregoing, this Section
         7.02 shall not apply to any Liability that is specifically pro-
         vided 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 Li-
         abilities relating to or arising under such Benefit Plans.
         Such steps shall include, without limitation and where ap-
         propriate, 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, trust-
         ees, custodians, recordkeepers and other fiduciaries and ser-
         vice providers to such Benefit Plans.  Except as specifically
         provided otherwise in this Agreement or in the agreement pro-
         vided 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 thereaf-
         ter, provide each other with all information as may reasonably
         be requested and necessary to administer each Benefit Plan ef-
         fectively 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 infor-
         mation 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 re-
         ferred 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.  

                                       
                                      -20-
                                       
                   (b)  This Agreement, and not the Tax Sharing Agree-
         ment, constitutes the sole agreement of the parties regarding
         responsibility for any excise taxes, penalties or similar lev-
         ies 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 sub-
         stantive laws of any other jurisdiction) as to all matters, in-
         cluding 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 Ef-
         fective 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 agree-
         ment of "Grace" or of "the parties" from and after the Effec-
         tive 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.
                                       
                                      -21-
                                       
                   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 Sec-
         tion headings contained in this Agreement are solely for the
         purpose of reference, are not part of the agreement of the par-
         ties hereto and shall not in any way affect the meaning or in-
         terpretation 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 circum-
         stance is determined by a court of competent jurisdiction to be
         invalid, void or unenforceable, the remaining provisions here-
         of, or the application of such provision to persons or circum-
         stances 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.

         party responsible for such filing under this Agreement.  The Pre-

         (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

         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,

         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.

                                       -6-




         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.

         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

         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 



                                       -7-




         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,

                                       -8-




         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.

                   Section 3.2.  Indemnities; Redetermined Tax
         Liabilities.  Except as otherwise provided in Article V:  

                   (a)  Indemnities.

                        (i)  Grace-Conn. shall be responsible for (w) any
         Tax for a Pre-Distribution Taxable Period (and any Hypothetical
         Pre-Distribution Tax for a Straddle Period) of 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,



                                       -9-




         was the common parent, (x) any Tax for a Pre-Distribution Taxable
         Period (and any Hypothetical Pre-Distribution Tax for a Straddle
         Period) of a Foreign Packco Subsidiary attributable to the
         Packaging Business reflected on a Tax Return filed by such
         Subsidiary on or before the Distribution Date 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 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 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.

                        (iv)  For purposes of determining the amount for
         which 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


                                      -10-




         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,


                                      -11-




         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



                                      -12-




         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

                                      -13-




         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,

                                      -14-




         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


                                      -15-




         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


                                      -16-




         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 



                                      -17-




         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.

                       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,
                                      -18-




         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
         consolidated 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.  



                                      -19-




                   (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 re-
         organization.  The foregoing sentence shall not apply to
         transactions in which Packco acquires another corporation,
         limited liability company, limited partnership, general
         partner-ship 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 conduct 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,


                                      -20-




         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


                                      -21-




         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



                                      -22-




         to and shall not constitute a waiver of any other remedy either
         party may be entitled to at law or at equity hereunder.


                                    ARTICLE VI.

                                   MISCELLANEOUS

                   Section 6.1.  Expenses.  Unless otherwise expressly
         provided in this Agreement, the Distribution Agreement or the
         Merger Agreement, each party shall bear any and all expenses that
         arise from their respective obligations under this Agreement.

                   Section 6.2.  Foreign Transfer Taxes.  Adjusted Foreign
         Transfer Taxes shall be shared by the parties as provided in the
         Distribution Agreement.  Audit adjustments and Final
         Determinations of such Taxes shall be governed by the
         Distribution Agreement.  This Agreement governs responsibilities
         of the parties with respect to filing Tax Returns relating to
         Foreign Transfer Taxes, paying Foreign Transfer Taxes reflected
         on such Tax Returns to the applicable governmental authority and
         conducting Proceedings relating to Foreign Transfer Taxes.  For
         purposes of determining indemnity and reimbursement obligations
         of the parties under this Agreement, Tax Items arising as a
         result of the Foreign Transfers (but not Tax Items arising from
         any actual distribution of Subsidiary Excess Cash) shall be
         disregarded, and the Pre-Distribution Schedules shall not reflect
         such Tax Items. 

                   Section 6.3.  Payments Paid or Received on Behalf of
         Indemnitees; Right to Designate Payee.  Each of Grace-Conn. and
         Grace shall be entitled to designate an Affiliate of such party
         as payee with respect to any payment that would otherwise be made
         to Grace-Conn. or Grace, respectively, under this Agreement.  Any
         payment received by Grace-Conn. or Grace, respectively, or its
         respective designees shall be received on behalf of the relevant
         Grace-Conn. Indemnitees or Packco Indemnitees.

                   Section 6.4.  Foreign Exchange Rate.  If any amount
         required to be paid hereunder is determined by reference to a
         Tax, Tax refund, Tax Benefit or Tax Detriment that 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 that such Tax is paid, such
         Tax refund is received or such Tax Benefit or Tax Detriment
         reduces or increases the amount of Tax or Tax refund that would
         otherwise be paid or received.

                   Section 6.5.  Amendment.  This Agreement may not be
         amended except by an agreement in writing, signed by the parties
         hereto.  Anything in this Agreement or the Distribution Agreement
         to the contrary notwithstanding, in the event and to the extent
         that there shall be a conflict between the provisions of this
         Agreement and the Distribution Agreement, the provisions of this
         Agreement shall control.

              TAX-FREE TRANSACTION CREATING TWO NEW PUBLIC COMPANIES

                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
                                        
                                        3
                                        

         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

         and Sealed Air transaction.

         TRANSACTION FACT SHEET

         THE TRANSACTION
         The Transaction has two components:

         1.   Prior to the merger, Grace's specialty chemicals
              operations, comprised of Grace Davison, Grace Construction
              Products and DAREX Container Products will be spun off to
              Grace shareholders.  The specialty chemicals operations
              will become a separate company, which will retain the
              Grace name and is expected to be listed on the New York
              Stock Exchange.  In addition, 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.

         2.   Grace's packaging business will be merged with Sealed Air
              to create the world's leading protective and specialty
              packaging company.  This company will be named Sealed Air,
              and its shares are expected to be listed on the New York
              Stock Exchange.

              Air and their respective shareholders

              Grace shareholders will own 63% on a fully diluted basis
              of the new Sealed Air and will retain ownership of 100% of
              the new Grace specialty chemicals company

              $5 billion:

                   $1.9 billion in common stock of the new Sealed Air
                   (40.9 million common shares of the new Sealed Air)

                   into approximately 31.8 million common shares)
                   $1.2 billion cash contribution to the new Grace, to
                   be used to pay down substantially all of its debt

              Excluding the effect of transaction and integration costs,

              Air's earnings per share going forward.
