                             DISTRIBUTION AGREEMENT


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


                                    RECITALS


                     A.  The Merger Agreement.  Grace and Sealed Air
         Corporation, a Delaware corporation ("SAC"), have entered
         into an Agreement and Plan of Merger, dated as of August 14,
         1997 (the "Merger Agreement"), pursuant to which, at the 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:

              value, as of the Distribution Date, of the assets of the
              Union Retirement Plan (as defined in the Benefits Agree-
              ment) and the assets that will be transferred to the

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

              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-

              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.

         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

         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-

         that cannot reasonably be separated or otherwise allocated as

         provided above, (i) all right, title and interest of Grace and
         its Subsidiaries shall be allocated to the Group as to which
         such Asset is predominantly used or held for use or 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


                                      - 20 -
                                   

         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.


                                      - 27 -

                                    
                   (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.

         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,

         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

         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
         member of the Packco Group obtains a letter of credit from a
         financial institution reasonably acceptable to New Grace and
         for the benefit of New Grace with respect to such obligation of

         cause their respective Groups to cooperate, to terminate, or to
         cause a member of the New Grace Group to be substituted in all
         respects for any member of the Packco Group in respect of, all
         obligations of any member of the Packco Group under any Grace-
         Conn. Liabilities for which such member of the Packco Group may

         otherwise.  The foregoing sentence does not apply to the Grace-
         Conn. Public Debt, which is governed by Section 2.06.  If such
         a termination or substitution is not effected by the Distribu-
         tion Date, (i) New Grace shall indemnify and hold harmless the
         Packco 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 Trea-
         surer of Grace, from and after the Distribution Date, New Grace

         Group 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 Packco Group is
         or may be liable unless all obligations of the Packco Group
         with respect thereto are thereupon terminated by documentation
         reasonably satisfactory in form and substance to the Chief Fi-
         nancial Officer, Treasurer or any Assistant Treasurer of Grace,
         provided that the limitations contained in clause (ii) shall 


                                      - 35 -
                                     
         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.

         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

         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

         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

                   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.

              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-

              shall have been consummated in all material respects, to

              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

              investment banking or appraisal firm in form and substance

              after giving effect to the transactions set forth in Ar-
              ticle II hereof, neither Grace nor New Grace and Grace--

              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.

         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
         of this Agreement.  Unless otherwise expressly stated, clauses
         beginning with the term "including" set forth examples only and
         in no way limit the generality of the matters thus exemplified.

                   SECTION 8.13  TERMINATION.  Notwithstanding any pro-
         vision hereof, following termination of the Merger Agreement,
         this Agreement may be terminated and the Distribution abandoned
         at any time prior to the Distribution Date by and in the sole
         discretion of the Board of Directors of Grace without the ap-
         proval of any other party hereto or of Grace's shareholders.
         In the event of such termination, no party hereto or to any
         Other Agreement shall have any Liability to any Person by rea-
         son of this Agreement or any Other Agreement.

                   SECTION 8.14  SAC REASONABLE CONSENT.  The parties
         hereto agree that any actions to be taken by Grace or New Grace
         under this Agreement that are not specifically required herein
         and that relate to Packco or the Packaging Business (including,
         without limitation, the transactions described in Article II)
         must be reasonably satisfactory to SAC.
