                                ARTICLE II.

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

               Section 2.1.  Manner of Filing.  All Tax Returns filed after
the Distribution Date and the Pre-Distribution Schedules shall be prepared
on a basis which is consistent with the consummation of the transactions as
set forth in the Distribution Agreement, the Grace Tax Matters Certificate,
the Sealed Air Tax Matters Certificate, the Tax Opinions and any opinions,
rulings, agreements or written advice relating to Foreign Transfers (in the
absence of a controlling change in law or circumstances) and shall be filed
on a timely basis (including extensions) by the party responsible for such
filing under this Agreement.  In the absence of a controlling change in law
or circumstances, all such Tax Returns and Pre-Distribution Schedules shall
also be prepared on a basis which is consistent with the treatment of each
of the Foreign Transfers in the jurisdictions listed on Exhibit A hereto as
a reorganization, pursuant to a plan of reorganization, within the meaning
of Section 368(a)(1)(D) of the Code.  The Pre-Distribution Schedules and
all Tax Returns in respect of a Pre-Distribution Taxable Period or portion,
ending on the Distribution Date of any Straddle Period, that include any
member of the New Grace Group or the Packco Group shall be prepared on the
basis of substantial authority or on a reasonable basis with (if
applicable) appropriate disclosure (each, "Substantial Authority");
provided, however, that such Schedules and Returns shall be prepared on a
basis consistent with the elections (other than elections relating to
carrybacks and carryforwards described in Section 3.3(a)), accounting
methods, conventions and principles of taxation used for the most recent
taxable periods of members of the New Grace Group for which Tax Returns
involving similar Tax Items have been filed, to the extent that a failure
to do so would result in a Tax Detriment, or a reduction in a Tax Benefit,
to a member of the Packco Group, as long as such consistent position has
Substantial Authority.  All Tax Returns in respect of a Post-Distribution
Taxable Period or portion, beginning after the Distribution Date, of any
Straddle Period, shall be prepared with Substantial Authority; provided,
however, that such Returns shall be prepared on a basis consistent with the
elections (other than elections relating to carrybacks and carryforwards
described in Section 3.3(a)), accounting methods, conventions and
principles of taxation used for the most recent taxable periods of members
of the New Grace Group for which Tax Returns involving similar Tax Items
have been filed, to the extent that a failure to do so would result in a
Tax Detriment, or a reduction in a Tax Benefit, to a member of the other
Group, as long as such consistent position has Substantial Authority.  In
the event of a conflict with respect to a Straddle Period between the
requirements of the immediately preceding sentence and the second preceding
sentence, the second preceding sentence shall prevail.  Subject to the
provisions of this Agreement, all decisions relating to the preparation of
Tax Returns shall be made in the sole discretion of the party responsible
under this Agreement for such preparation.  Grace shall provide Grace-Conn.
with copies of all Tax Returns filed after the Distribution Date that
relate to any member of the New Grace Group.  Grace-Conn. shall provide
Grace with a copy of any portion of a Tax Return necessary to confirm
Grace-Conn.'s entitlement to payment hereunder in respect of a carryback or
refund.

               Section 2.2.  Pre-Distribution and Straddle Period Tax Returns.

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

               (b) With respect to any Del Prepared Return that has not been
filed as of the Distribution Date and relates to a Pre-Distribution Taxable
Period or a Straddle Period, Grace-Conn. shall, 25 calendar days before the
due date (including extensions) for such Return, provide Grace with a schedule
(collectively, the "Pre-Distribution Schedules") detailing the computation of
(i) in the case of a Pre-Distribution Taxable Period, the Tax and/or Overall
Tax Benefit and (ii) in the case of a Straddle Period, the Hypothetical
Pre-Distribution Tax and/or Hypothetical Pre-Distribution Overall Tax Benefit,
in either case, attributable to the member or members of the New Grace Group
or the Packco Group included in such Return.  Any Pre-Distribution Schedule
relating to a Pre-Distribution Taxable Period shall be delivered to Grace in
the form of a completed, but unexecuted Tax Return.  If Grace so requests,
Grace-Conn. shall discuss with Grace the preparation of, and allow Grace
periodically to review major issues with respect to, any Pre-Distribution
Schedule.  In the event that Grace disagrees with any Tax Item reflected (or
anticipated to be reflected) on a Pre-Distribution Schedule and demonstrates
(by means of a written explanation in sufficient detail to permit such
conclusion to be verified) its conclusion that Grace-Conn. has failed to comply
with the requirements of the third sentence of Section 2.1 hereof (a
"Consistency/Basis Disagreement"), Grace-Conn. shall explain its calculation
of such Tax Item within 14 days of receipt of Grace's written explanation.
The parties shall attempt in good faith mutually to resolve any
Consistency/Basis Disagreements prior to the due date for filing the relevant
Tax Return.  Notwithstanding any other provision of this Agreement, with
respect to estimated Tax payments to a foreign governmental authority for the
first quarter of 1998 that are due before the parties have agreed on the
amount in connection therewith for which Grace-Conn. is responsible hereunder,
(I) Grace shall estimate in good faith and in accordance with past practice and
make such estimated Tax payment, (II) Grace shall promptly provide such
estimate to Grace-Conn., (III) Grace-Conn. shall deliver to Grace the
applicable Pre-Distribution Schedule reasonably promptly after the
Distribution Date (provided that  Grace and its Affiliates reasonably and
promptly cooperate with Grace-Conn. in the preparation thereof), (IV)
Grace-Conn. shall not be required to make any payment in respect of such
estimated Taxes to Grace until five days after the date that the parties agree
on such Pre-Distribution Schedule (the "Agreed Date") (and such payment shall
not exceed the amount of such estimated Tax paid, shall otherwise be
determined based on the Pre-Distribution Schedule as distinguished from the
estimated Tax paid, and shall be made in immediately available funds), and
(IV) such payment shall bear interest from the time that payment is due to the
applicable governmental authority until the earlier of the date that payment
is made by Grace-Conn. and five days after the Agreed Date at the rate of
interest charged for Eurodollar or LIBOR loans under Grace-Conn.'s principal
senior bank debt agreement.  If such payment by Grace-Conn. is not made by the
fifth day after the Agreed Date, then such payment shall bear interest from
the fifth day after the Agreed Date until the date that payment is made by
Grace-Conn. at the rate that is two percent in excess of the rate set forth in
clause (IV) of the preceding sentence.

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

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

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


                               ARTICLE III.

Agreement for filing the Tax Return pursuant to which such Taxes are due;

Prepared Returns for Pre-Distribution Taxable Periods or Straddle Periods,
Grace-Conn. shall pay Grace the amount, if any, of the Tax or Hypothetical
Pre-Distribution Tax, as the case may be, if any, reflected in the Pre-
Distribution Schedule relating to such Tax Return attributable to the
member or members of the New Grace Group or the Packco Group included in
such Return (and in the case of the Business Tax and Real Estate Tax due to
France or a political subdivision thereof (and other Taxes due to any
jurisdiction based on analogous principles), with respect to Post-
Distribution Periods in 1998, Grace-Conn. shall pay Grace the amount of any
Tax liability attributable to the New Grace Business).  Such payment shall
be made, at Grace-Conn.'s discretion, either in immediately available funds
on the morning of the relevant date when payment is due to the governmental
authority in respect of such Tax Return or, if not in immediately available
funds, two business days prior to such due date.  Grace shall forward any
such payment that it receives from Grace-Conn. to the appropriate taxing
authority.

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

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

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

Item.

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

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

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

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

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

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

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

               (c) Calculation and Payment of Amounts.

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

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

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

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

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

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

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


                                ARTICLE IV.

            INDEMNITY, COOPERATION AND EXCHANGE OF INFORMATION
            --------------------------------------------------

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

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

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

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

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

               Section 4.3.  Cooperation and Exchange of Information.

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

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

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

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

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


                                ARTICLE V.

                  CERTAIN POST-DISTRIBUTION TRANSACTIONS
                  --------------------------------------

               Section 5.1  Sealed Air and Packco Group Covenants.

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

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

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

               (c) Until the first day after the Restriction Period, no Sealed
Air Party nor any member of the Packco Group shall sell or otherwise issue to
any Person, or redeem or otherwise acquire from any Person (other than any
member of the Packco Group), any Equity Securities of Grace or any other
member of the Packco Group; provided, however, that (i) purchases that, in the
aggregate, meet the requirements of Section 4.05(1)(b) of Revenue Procedure
96-30 shall not constitute a redemption or acquisition of stock of Grace for
purposes of this Section 5.1(c), (ii) if required by law, any member of the
Packco Group may issue a de minimis number of Equity Securities of such member
to any person in order to qualify such person to serve as an officer or
director of such member and (iii) Grace may issue, as compensation for
services or pursuant to the exercise of compensatory stock options, Equity
Securities of Grace that do not exceed in the aggregate ten percent of the
Equity Securities of Grace.

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

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

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

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

               Section 5.2  New Grace Covenants.

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

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

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

               (c) Until the first day after the Restriction Period, no member
of the New Grace Group shall sell or otherwise issue to any Person, or redeem
or otherwise acquire from any Person (other than any member of the New Grace
Group), any Equity Securities of New Grace or any other member of the New
Grace Group; provided, however, that (i) purchases that, in the aggregate,
meet the requirements of Section 4.05(1)(b) of Revenue Procedure 96-30 shall
not constitute a redemption or acquisition of stock of New Grace for purposes
of this Section 5.2(c), (ii) if required by law, any member of the New Grace
Group may issue a de minimis number of Equity Securities of such member to any
person in order to qualify such person to serve as an officer or director of
such member and (iii) New Grace may, pursuant to shareholder-approved equity
compensation plans, issue, as compensation for services or pursuant to the
exercise of compensatory stock options, Equity Securities of New Grace.

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

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

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

               Section 5.3.  Responsibility for Taxes.

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

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

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

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

               Section 5.5.  Distribution.  For purposes of this Article V
only, "Distribution" shall mean the contribution by Grace-Conn. of assets
and liabilities to Packco, the distribution of cash by Packco to Grace-
Conn., the distribution by Grace-Conn. of the stock of Packco to Grace, the
contribution of cash and the stock of Grace-Conn. to New Grace, the loan
from New Grace to Grace-Conn. and the distribution by Grace of the stock of
New Grace to the shareholders of Grace, each as provided in the
Distribution Agreement.


                                ARTICLE VI.

                               MISCELLANEOUS
                               -------------

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

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

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

               Section 6.4.  Foreign Exchange Rate.  If any amount required to
be paid hereunder is determined by reference to a Tax, Tax refund, Tax Benefit
or Tax Detriment that is denominated in a currency other than United States
dollars, such payment shall be made in United States dollars and the amount
thereof shall be computed using the Foreign Exchange Rate for such currency
determined as of the date that such Tax is paid, such Tax refund is received
or such Tax Benefit or Tax Detriment reduces or increases the amount of Tax or
Tax refund that would otherwise be paid or received.

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

               Section 6.6.  Notices.  All notices and other communications
hereunder shall be in writing and shall be delivered by hand including
overnight business courier or mailed by registered or certified mail (return
receipt requested) to the parties at the following addresses (or at such other

               Section 6.8.  Application to Present and Future Subsidiaries.
This Agreement is being entered into by Grace-Conn. and Grace on behalf of

of the parties hereunder shall be specifically enforceable.
