              2.01  General Rule.

              (a) Tenneco Liability. Tenneco shall be liable for all Taxes not
specifically allocated to Packaging Company under this Section 2. Tenneco shall
indemnify and hold harmless the Packaging Group from and against any liability
for Taxes for which Tenneco is liable under this Section 2.01(a).

              2.02  Allocation of United States Federal Income Tax.  Except as
provided in Sections 2.05 and 2.06:

       (a) Allocation of Tax and Tax Attributes Relating to the 1999 Tax Period.
With respect to the Tenneco Federal Consolidated Return for the tax period
ending December 31, 1999 (the "1999 Tax Period"), the allocation and use of net
operating loss carryforwards and current year losses, and the allocation of
Consolidated Tax Liability, if any, shall be made as follows:

              (i) STEP ONE. The net operating losses attributable to the tax
period ended December 31, 1997 (the "1997 Loss Carryforward") and the net
operating losses attributable to the tax period ended December 31, 1998 (the
"1998 Loss Carryforward") shall be allocated between the Tenneco Group and
Packaging Group based upon the legal entities that incurred such losses
(treating the income of any member of the Tenneco Affiliated Group for the
relevant tax period

                                       -8-

   9



as reducing the losses of each legal entity included in the Tenneco Affiliated
Group on a pro rata basis in accordance with Treasury Regulation ss.
1.1502-21(b)(2).

              (ii) STEP TWO. The taxable income (or loss) of each of the Tenneco
Group and Packaging Group for the portion of the 1999 Tax Period ending on
September 30, 1999 (the "Benchmark Period") shall be computed (the "Benchmark
Income (or Loss) Allocation ") subject to adjustment for material divestments,
the costs of the Debt Realignment, and similar items.

              (iii) STEP THREE. The taxable losses, if any, incurred by any
member of the Tenneco Affiliated Group for the Benchmark Period shall be deemed
to be utilized first to offset the taxable income, if any, of each other member
of the Tenneco Affiliated Group for such tax period (which losses shall be
deemed to be utilized by such members on a pro rata basis). Next, the 1997 Loss
Carryforward shall be deemed to be utilized, on a pro rata basis, to offset the
taxable income of each member of the Tenneco Affiliated Group. Finally, to the
extent the taxable income for such period exceeds the losses for such period and
the 1997 Loss Carryforward, the 1998 Loss Carryforward shall be deemed to be
utilized, on a pro rata basis, to offset the remaining taxable income of each
member of the Tenneco Affiliated Group. Neither Tenneco nor Packaging Company
shall have any obligation to pay or reimburse the other party for utilization of
such party's net operating losses under this Step Three. Each Group's allocable
share of the 1997 Loss Carryforward and 1998 Loss Carryforward following the
utilization of losses described in this Step Three shall be referred to as such
Group's "Benchmark 1997 Loss Carryforward Allocation" and "Benchmark 1998 Loss
Carryforward Allocation," respectively. In the event the 1997 Loss Carryforward
and 1998 Loss Carryforward are fully utilized, the Benchmark 1997 Loss
Carryforward Allocation and the Benchmark 1998 Loss Carryforward Allocation
shall be deemed to equal zero.

              In the event the Tax Return for the tax period ended December 31,
1998 has not been filed at the time the Benchmark 1997 and Benchmark 1998 Loss
Carryforward Allocations are made pursuant to Step Three, the parties shall use
an agreed upon estimate of the net operating losses for the tax period ended
December 31, 1998, and within 30 days of the filing the Tax Return for such tax
period, the Benchmark 1997 Loss Carryforward Allocation and Benchmark 1998 Loss
Carryforward Allocation shall be redetermined. In the case of such
redetermination if Packaging Company's Benchmark 1997 Loss Carryforward
Allocation or Benchmark 1998 Loss Carryforward Allocation, as redetermined,
exceeds the amount of such allocation as initially determined under Step Three,
Packaging Company shall pay to Tenneco an amount equal to such excess multiplied
by 35%, and if Packaging Company's Benchmark 1997 Loss Carryforward Allocation
or Benchmark 1998 Loss Carryforward Allocation, as redetermined, is less than
Packaging Company's Benchmark 1997 Loss Carryforward Allocation or Benchmark
1998 Loss Carryforward Allocation, Tenneco shall pay to Packaging Company an
amount equal to such difference multiplied by 35%.

              (iv) STEP FOUR. The taxable income (or loss) of each of the
Tenneco Group and the Packaging Group for the 1999 Tax Period shall be computed
(in the same manner as described in

                                       -9-

   10



Step Two) based on the Tax Return as filed for such tax period (the "Final
Income or Loss Allocation").

              (v) STEP FIVE. Based on the Tax Return as filed for the 1999 Tax
Period, the taxable losses, if any incurred by any member of the Tenneco Group
or Packaging Group for such period shall be deemed to be utilized first to
offset the taxable income, if any, of each other member of the Tenneco
Affiliated Group for such period (which losses shall be deemed to be utilized by
such members on a pro rata basis). Next, the 1997 Loss Carryforward shall be
deemed to be utilized, on a pro rata basis, to offset the taxable income of each
member of the Tenneco Affiliated Group. Finally, to the extent the taxable
income for such period exceeds the losses for the current period and the 1997
Loss Carryforward, the 1998 Loss Carryforward shall be deemed to be utilized, on
a pro rata basis, to offset the remaining taxable income of each member of the
Tenneco Affiliated Group. Each Group's allocable share of the 1997 Loss
Carryforward and 1998 Loss Carryforward following the utilization of losses
described in this Step Five shall be referred to as the "Final 1997 Loss
Carryforward Allocation" and "Final 1998 Loss Carryforward Allocation,"
respectively.

              (vi) STEP SIX. Within sixty (60) days of filing the Tenneco
Federal Consolidated Tax Return for the 1999 Tax Period, the Packaging Group
shall compute the "True-Up Amount," which amount shall equal (I) the sum of (A)
the Packaging Group's' Final Income (or Loss) Allocation less the Packaging
Group's Benchmark Income or (Loss) Allocation (any loss allocation shall be
treated as a negative number for purposes of this computation) plus (B) the
Packaging Group's Final 1997 Loss Carryforward less the Packaging Group's
Benchmark 1997 Loss Carryforward (as redetermined under Step Three, if
applicable), plus (C) the Packaging Group's Final 1998 Loss Carryforward less
the Packaging Group's Benchmark 1998 Carryforward (as redetermined under Step
Three, if applicable), multiplied by (II) 35%.

              (vii) STEP SEVEN. In the event the Packaging Group's True-Up
Amount is positive, Packaging Company shall pay such amount to Tenneco, and in
the event the Packaging Group's True-Up Amount is negative, Tenneco shall pay
such amount to Packaging Company.

              Schedule A attached hereto sets forth the parties' agreement as to
the determinations required under Steps One, Two and Three of this Section
2.02(a). Schedule B attached hereto provides an example of the manner in which
Steps Four, Five and Six are to be computed. The actual determination required
to be made under Steps Four, Five and Six will be based on the information
contained on the Tax Return as filed for the 1999 Tax Period.

              (b) Allocation of Tenneco Federal Consolidated Return Tax
Adjustments. If there is any adjustment to the reported Tax liability with
respect to any Tenneco Federal Consolidated Return, or to such Tax liability as
previously adjusted, Packaging Company shall be liable to Tenneco for the excess
(if any) of--

                                      -10-

   11



                    (i) the Consolidated Tax Liability of the Packaging Group
       computed as if all members of the Packaging Group included in the Tax
       Return had filed a consolidated Tax Return for such members based on the
       Tax Items of such members as so adjusted (the "Packaging Group Recomputed
       Federal Tax Liability"); over

                    (ii) the Consolidated Tax Liability of the Packaging Group
       computed as if such members of the Packaging Group had filed a
       consolidated Tax Return for such members based on the Tax Items of such
       members as reported (or, if applicable, as previously adjusted) (the
       "Packaging Group Prior Federal Tax Liability"). Solely with respect to
       the Tenneco Federal Consolidated Return for the 1999 Tax Period, the
       Packaging Group Prior Federal Tax Liability with respect to such Tax
       Return shall equal the Consoli dated Tax Liability allocable to the
       Packaging Group with respect to such Tax Return under Section 2.02(a)
       hereof.

If the Packaging Group Prior Federal Tax Liability exceeds the Packaging Group
Recomputed Federal Tax Liability, Tenneco shall be liable to Packaging Company
for such excess. For purposes of this Section 2.02(b), if the Packaging Group
has a net operating loss after taking into account the adjustments allocable to
such Group, the Recomputed Federal Tax Liability of the Group shall be less than
zero to the extent such net operating loss produces a Tax Benefit in
consolidation for the applicable taxable year (which shall be determined
applying the principles of Section 4.07(c)(ii)). For example, if the Packaging
Group's Prior Federal Tax Liability for Year X was $50 and taking into account
all adjustments for Year X, Packaging Group has a net operating loss of $40
resulting in a Tax Benefit of $14 (determined by computing the Consoli dated Tax
Liability for such Tax Period with and without the net operating loss), then the
Packaging Group's Recomputed Federal Tax Liability for Year X would be negative
$14, and Tenneco would be liable to Packaging Company in the amount of $64, i.e.
($50 - (-$14)).

                    (c) Allocation of AMT Credits. Notwithstanding anything to
the contrary herein, the parties hereby agree that Packaging Company shall be
allocated the entire amount of the alternative minimum tax credits (as defined
in Section 53 of the Code) arising from the imposition of alternative minimum
tax (as defined in Section 55 of the Code) (i) with respect to Tenneco's tax
periods ending on or before December 31, 1999 and (ii) with respect to El Paso's
tax years ended December 31, 1993, December 31, 1994 and December 31, 1995 and
allocable to Tenneco under the letter agreement between Tenneco and El Paso
Natural Gas Company dated October 18, 1999 (collectively, the "AMT Credits").
Tenneco and Packaging Company agree that this allocation is equitable since the
alternative minimum taxable income in the foregoing tax periods is attributable
to the Packaging Group. In the event there is a determination by an applicable
Tax Authority that the AMT Credits are not allocable to Packaging and are
allocable to Tenneco, Tenneco shall reimburse Packaging for the AMT Credits
allocated to Tenneco when, and to the extent that, such credits are utilized to
reduce Taxes on a Federal Income Tax Return of Tenneco.

              2.03 Allocation of State Income Taxes. Except as provided in
Sections 2.04, 2.05 and 6.03, State Income Taxes shall be allocated as follows:

                    (a) Allocation of State Income Tax Liabilities for
Post-Distribution State Income Tax Returns.

                           (i) Separate Company Taxes.  In the case of any
Separate Company State Income Tax with respect to a Post-Distribution State
Income Tax Return, Packaging Company shall be liable for such Tax imposed on
any members of the Packaging Group.

                           (ii) Consolidated or Combined State Income Taxes. In
the case of any Consolidated or Combined State Income Tax with respect to
a Post-Distribution State Income Tax Return, the Consolidated or Combined State
Income Tax liability shall be allocated between the Tenneco Group and the
Packaging Group as follows:

                                 (A) Each Group shall compute its "Hypothetical
State Tax Liability," which shall equal the State Income Tax liability of
such Group (which number shall be deemed to be zero if such Group has net
operating losses for such Tax Period), computed as if all members of such Group
included in the computation of such Tax had filed a consolidated or combined Tax
Return for such Group's members based on the income, apportionment factors, and
other items of such members.

                                 (B) In the event the Estimated Tax Payments (as
defined below) exceed, or are less than, the actual State Income Tax
liability shown on the Consolidated and Combined State Income Tax Return such
excess or deficit, as the case may be, shall be shared by the Tenneco Group and
the Packaging Group. Each Group's share shall be determined by multiplying such
excess or deficit by a fraction, (a) the numerator of which is the Hypothetical
State Tax Liability of such Group, and (b) the denominator of which is the sum
of the Hypotheti cal State Tax Liability of the Tenneco Group and the Packaging
Group, with appropriate payments being made by Packaging Company to Tenneco, or
by Tenneco to Packaging Com pany, to achieve the appropriate sharing of such
excess or deficit. The term "Estimated Tax Payments" shall mean any and all
estimated payments made in connection with the Combined or Consolidated State
Income Tax Return filed for such Tax Period; provided, however, such amount
shall (i) exclude any estimated Tax payments made after the Distribution Date,
(ii) include any overpayments of Combined or Consolidated State Income Tax for
any prior Tax Periods which are carried forward and applied as payments on the
Combined or Consolidated State Income Tax Returns for the applicable Tax Period,
and (iii) include any extension payments paid by Packaging Company for the
Combined or Consolidated State Income Tax Return filed for such Tax period.

                    (iii) Post-Distribution Estimated Tax and Extension
Payments. Notwithstand ing anything to the contrary in the foregoing, in the
case of both Separate Company Taxes and Consolidated or Combined Income Taxes,
Packaging Company shall pay to the appropriate State

                                      -12-

   13



Tax Authority any estimated Taxes with respect to the Tax Period ended December
31, 1999 due after the Distribution Date. Packaging Company shall also pay to
the appropriate State Tax Authority any extension payments for Consolidated or
Combined State Income Taxes, and Separate Company Taxes imposed on members of
Packaging Group, with respect to the Tax Period ended December 31, 1999 due
after the Distribution Date. Tenneco shall reimburse Packaging Company for (i)
any estimated Tax payments made by Packaging Company after the Distribution Date
with respect to Separate Company Taxes imposed on members of the Tenneco Group
and (ii) any and all estimated Tax payments made by Packaging Company after the
Distribution Date with respect to any Consolidated or Combined State Income Tax.
Tenneco shall be responsible for payment of any extension payments for Separate
Company Taxes imposed on members of the Tenneco Group with respect to the Tax
Period ended December 31, 1999, due after the Distribution Date.

                    (b)    Allocation of State Income Tax Adjustments.

       (i) Combined or Consolidated State Income Tax Adjustments. If there is
       any adjustment to the amount of Consolidated or Combined State Income Tax
       reported on any Tax Return (or as previously adjusted), the liability of
       the Packaging Group shall be recomputed as provided in this subparagraph.
       Packaging Company shall be liable to Tenneco for the excess (if any) of--

                           (A) the State Income Tax liability computed as if all
              members of the Packaging Group included in the Tax Return had
              filed a consolidated or combined Tax Return for such members based
              on the income, apportionment factors, and other items of such
              members as so adjusted (the "Packaging Group Recomputed State Tax
              Liability"); over

                           (B) the State Income Tax liability computed as if
              such members of the Packaging Group had filed a consolidated or
              combined Tax Return for such members based on the income,
              apportionment factors, and other items of such members as reported
              (or, if applicable, as previously adjusted) (the "Packaging Group
              Prior State Tax Liability").

       If the Packaging Group Prior State Tax Liability exceeds the Packaging
       Group Recomputed State Tax Liability, Tenneco shall be liable to
       Packaging Company for such excess. For purposes of this paragraph, (i) if
       the Packaging Group has a net operating loss after taking into account
       the adjustments allowable to such Group, the Packaging Group Recomputed
       State Tax Liability shall be less than zero to the extent such net
       operating loss produces a Tax Benefit for purposes of the applicable
       Consolidated or Combined State Income Tax and (ii) the determination and
       payment of estimated Taxes (including the determination and payment of
       any Tax required to be paid with a request for an extension of time to
       file a Tax Return) shall not be treated as an adjustment to the related
       Consolidated or Combined State Income Tax.

                                      -13-

   14




       (ii) Separate Company Taxes. In the case of any adjustment to the amount
       of a Separate Company Tax Liability, Packaging Company shall be liable
       for such Tax imposed on members of the Packaging Group, and Tenneco shall
       be liable for such Tax imposed on members of the Tenneco Group.

              2.04  Allocation of Other Taxes.

              (a) General. Except as provided in Section 2.04 (b) and (c) and
Section 2.05, all Taxes other than those specifically allocated pursuant to
Sections 2.02 and 2.03 shall be allocated based on the legal entity on which the
legal incidence of the Tax is imposed (provided, however, that in the event the
legal entity on which the legal incidence of the tax is imposed is a member of a
group including members of both the Packaging Group and Tenneco Group, the tax
shall be allocated between the Tenneco Group and Packaging Group based on each
Group's respective share of the taxable income giving rise to such Tax. As
between the parties to this Agreement, Packaging Company shall be liable for all
Taxes imposed on any member of the Packaging Group. The Companies believe that
there is no Tax not specifically allocated pursuant to Sections 2.02 and 2.03
which is legally imposed on more than one legal entity (e.g., joint and several
liability); however, if there is any such Tax, it shall be allocated in
accordance with past practices as reasonably determined by the affected
Companies, or in the absence of such practices, in accordance with any
allocation method agreed upon by the affected Companies.

              (b) German Restructuring. Notwithstanding anything to the contrary
in this Agreement, with respect to the Corporate Restructuring Transactions
involving the restructuring of the German entities (i.e., the members of the
Tenneco Affiliated Group organized under the laws of Germany) (the "German
Restructuring Transactions"), the parties agree as follows:

                    (i) Packaging Company shall be liable for any and all
                    Transfer Taxes incurred as a result of the German
                    Restructuring Transactions.

                    (ii) Tenneco Deutschland Holdinggesellschaft mBH's ("Tenneco
                    Deutschland") German Tax losses shall be utilized to the
                    fullest extent permitted under Ger man Tax Law to offset
                    income realized in connection with the German Restruc turing
                    Transactions and Packaging Company shall have no obligation
                    to reim burse or otherwise compensate Tenneco for the use of
                    such Tax losses; pro vided, however, that (X) in the event
                    the German Tax Authority makes a final determination that
                    the income realized in connection with the German Restruc
                    turing Transactions is greater than the amount reported on
                    the Tax Return as originally filed, Packaging Company shall
                    pay to Tenneco Deutschland an amount equal to the additional
                    German Tax loss used to offset Tenneco Deutsch land's
                    increased income multiplied by the applicable German Tax
                    rate, and (Y) in the event the German Tax Authority makes a
                    final determination that the income realized in connection
                    with the German Restructuring Transactions is

                                      -14-

   15



                    less than the amount reported on the Tax Return as
                    originally filed, Tenneco Deutschland shall pay to Packaging
                    Company an amount equal to the German Tax loss restored as a
                    result of such determination multiplied by the applicable
                    German Tax rate.

                    (iii) In the event any member of the Packaging Group is
                    required to make profit and absorption payments to Tenneco
                    Deutschland after the Distribution Date, such payments shall
                    be promptly repaid to Tenneco Packaging Deutschland Holding
                    Gesellschaft mBH as an adjustment to purchase price with
                    respect to Tenneco Deutschland's sale of such member to
                    Tenneco Packaging Deutschland Holding Gesellschaft mBH
                    pursuant to the German Restructuring Transactions.

                    (iv) In the event the German Tax Authority disallows Tenneco
                    Deutschland's Organschaft status for any reason whatsoever,
                    Tenneco Deutschland shall pay to Packaging Company the Tax
                    Benefit realized by Tenneco Deutschland by reason of
                    claiming input credits arising out of deemed dividend
                    payments made by members of the Packaging Group.

       (c) United Kingdom Restructuring. Notwithstanding anything to the
contrary in this Agreement, with respect to the Corporate Restructuring
Transactions involving the restructuring of the United Kingdom entities (i.e.,
the members of the Tenneco Affiliated Group organized under the laws of United
Kingdom) (the "UK Restructuring Transactions"), the Companies agree as follows:

                    (i)    Packaging Company shall be liable for any and all
                           Transfer Taxes (includ ing, without limitation, any
                           stamp duty) incurred as a result of the UK
                           Restructuring Transactions.

                    (ii)   Each Group shall be entitled to cause any of its
                           members to surrender such member's Tax losses for
                           group relief or consortium relief (or other amounts
                           eligible for group or consortium relief) to
                           another member of such Group; provided, however,
                           that if the Tax losses of a Group cannot be
                           utilized by the members of such Group, the Tax
                           losses shall be surren dered for group relief or
                           consortium relief to the members of the other
                           Group, as designated in writing by the parent
                           company of such other Group (and such other Group
                           shall have no obligation to reimburse or otherwise
                           compensate the surrendering Group for its losses).

              2.05  Transaction and Other Taxes.

              (a) General. Except as otherwise provided in this Section 2.05,
any and all liability for Taxes resulting from the Transactions shall be
allocated as follows:

                                      -15-

   16



                    (i) Any sales and use, gross receipts or other Transfer
Taxes imposed on the transfers occurring pursuant to the Transactions (together
with any Tax resulting from any income or gain recognized under Treasury
Regulation Sections 1.1502-13 or 1.1502-19 (or any other corresponding
provisions of other applicable Tax Laws) as a result of the Transactions) shall
be allocated to the legal entity on which the legal incidence of the Tax is
imposed. As between the parties to this Agreement, Packaging Company shall be
liable for all Taxes imposed on any member of the Packaging Group and Tenneco
shall be liable for all Taxes imposed on any member of the Tenneco Group.

                    (ii) Any Tax liability resulting from any income or gain
recognized as a result of any of the transactions contemplated by the
Distribution Agreement failing to qualify for tax-free treatment under Code
Sections 332, 351, 355, 361 or other provisions of the Code (as contem plated by
the Ruling Request) or corresponding provisions of other applicable Tax Laws,
shall be allocated fifty percent (50%) to Tenneco and fifty percent (50%) to
Packaging Company.

              (b) Indemnity for Inconsistent Acts. Tenneco or Packaging Company,
as the case may be, shall be liable for, and shall indemnify and hold harmless
the members of the other Group from and against any liability for, any
Restructuring Tax to the extent arising from any breach by such party of its
representations or covenants under Section 11.

              (c) Indemnity for Liability Under Code Section 355(e).
Notwithstanding anything to the contrary in this Section 2.05, any Tax liability
incurred by Tenneco under Code Section 355(e) (or any corresponding provision of
other applicable Tax Laws) by reason of the acquisi tion by one or more persons
of a "50-percent or greater interest" (as such term is defined in Code Section
355(d)(4)) in Tenneco or Packaging Company (a "50% Ownership Shift") shall be
allocated to that entity (i.e., Tenneco or Packaging Company) with respect to
which such Ownership Shift has occurred.

       2.06   Liability Under 1996 Spin-Off Tax Sharing Agreement.

              (a) With respect to any Tax liability imposed on or incurred by
Tenneco (or any Tax Benefit owing to Tenneco) under the Tax Sharing Agreement
dated as of December 11, 1996, as amended, by and among Tenneco, Newport News
Shipbuilding Inc., El Paso Natural Gas Company, and El Paso Tennessee Pipeline
Co. ("Old Tenneco")(the "1996 Spin-Off Tax Sharing Agreement), Packaging Company
shall be liable for, and shall indemnify and hold the Tenneco Group harmless
from, any and all such Tax liabilities (and Packaging Company shall be entitled
to any and all such Tax Benefits) except to the extent such Tax liability (or
such Tax Benefit) would be treated as allocable to the Tenneco Group under the
terms of Sections 2.01 through 2.04 hereof, in which case the Tenneco Group
shall be liable for such Tax liability and shall be entitled to such Tax
Benefit. Any amount owed by Packaging Company under this Section 2.06 shall be
paid by Packaging Company to Tenneco within 30 days from the date of written
notice and demand from Tenneco evidencing the payment of such amount by Tenneco
in accordance with the terms of the 1996 Spin-Off Tax Sharing Agreement. Any
amount due to Packaging

                                      -16-

   17



Company under this Section 2.06 shall be paid to Packaging Company by Tenneco
within 30 days from the date of receipt of such amount by Tenneco in accordance
with the terms of the 1996 Spin-Off Tax Sharing Agreement.

              (b) The Companies agree that in the case of any dispute or
controversy under the 1996 Spin-Off Tax Sharing Agreement, (i) each Company
shall control the portion of such dispute or controversy that directly and
exclusively relates to a Tax liability or Tax Benefit borne by such Company
under the terms hereof, and (ii) to the extent any issue involved in, or aspect
of, such dispute or controversy does not directly and exclusively relate to the
Tax liability or Tax Benefits of one Company under the terms hereof, the
Companies shall jointly control and otherwise handle such issue or matter in
accordance with the rules for defense or prosecution of Joint Adjustments in
Section 9.02(b) hereof. In furtherance of the foregoing, Tenneco shall, upon
Packaging Company's request, execute such powers of attorney or other
documentation as reasonably determined by Packaging Company to be necessary or
appropriate to permit Packag ing Company to fully exercise its rights under this
Section 2.06(b). Each of Tenneco and Packaging Company agree that, with respect
to any issue which involves or could involve the other Company's liability (or
entitlement to payment) under the 1996 Spin-Off Tax Sharing Agreement pursuant
to this Section 2.06, it shall not have the right to settle such issue without
the prior written consent of such other Company.

       SECTION 3.   PRORATION OF TAXES FOR STRADDLE PERIODS.

              3.01 General Method of Proration. In the case of any Straddle
Period, Tax Items shall be apportioned between Pre-Distribution Periods and
Post-Distribution Periods in accor dance with the principles of Treasury
Regulation Section 1.1502-76(b) as reasonably interpreted and applied by the
Companies. No election shall be made under Treasury Regulation Section
1.1502-76(b)(2)(ii) (relating to ratable allocation of a year's items). If the
Distribution Date is not an Accounting Cutoff Date, the principles of Treasury
Regulation Section 1.1502-76 (b)(2)(iii) will be applied to ratably allocate the
items (other than extraordinary items described in Treasury Regulation Section
1.1502-76(b)(2)(ii)(C)) for the month which includes the Distribu tion Date.

              3.02 Transaction Treated as Extraordinary Item. In determining the
apportionment of Tax Items between Pre-Distribution Periods and
Post-Distribution Periods, any Tax Items relating to the Transactions shall be
treated as an extraordinary item described in Treasury Regulation Section
1.1502-76(b)(2)(ii)(C) and shall be allocated to Pre-Distribution Periods, and
any Taxes related to such items shall be treated under Treasury Regulation
Section 1.1502- 76(b)(2)(iv) as relating to such extraordinary item and shall be
allocated to Pre-Distribution Periods.

                                      -17-

       SECTION 4.   PREPARATION AND FILING OF TAX RETURNS.

              4.01 General. Except as otherwise provided in this Section 4, Tax
Returns shall be prepared and filed when due (including extensions) by the
person obligated to file such Tax Returns under the Code or applicable Tax Law.
The Companies shall provide, and shall cause their Affiliates to provide,
assistance and cooperate with one another in accordance with Section 7 with
respect to the preparation and filing of Tax Returns, including providing
informa tion required to be provided in Section 7.

              4.02 Packaging Company's Responsibility. Packaging Company has the
exclusive obligation and right to prepare and file, or to cause to be prepared
and filed:

              (a) Tenneco Federal Consolidated Returns for Tax Periods ending on
or before December 31, 1999.

              (b) The U.S. federal Income Tax return for the affiliated group
(as that term is defined in Code Section 1504) of which Tenneco International
Holding Corp. is the common parent for Tax Periods ending on or before December
31, 1999.

              (c) Tax Returns for Separate Company State Income Taxes or
Consolidated or Combined State Income Taxes which the Companies reasonably
determine, in accordance with Tenneco's past practices, are required to be filed
by the Companies or any of their Affiliates for Tax Periods ending on or before
December 31, 1999 (including without limitation, the filing of amended Tax
Returns to take into account Federal Income Tax adjustments or Carryback Items).

              (d) Tax Returns that are required to be filed by the members of
the Packaging Group.

Nothing in this Section 4.02 shall impose on Packaging Company any liability for
any failure to file any Tax Return, or for failure to file any Tax Return when
due, with respect to any Pre-Distribution Period if the due date for such return
(including extensions) was prior to the Distribution Date.

              4.03 Tenneco Responsibility. Tenneco shall prepare and file, or
shall cause to be prepared and filed, Tax Returns required to be filed by or
with respect to members of the Tenneco Group other than those Tax Returns which
Packaging Company is required to prepare and file under Section 4.02. The Tax
Returns required to be prepared and filed by Tenneco under this Section 4.03
shall include (a) the Tenneco Federal Consolidated Return for Tax Periods ending
after December 31, 1999, (b) the U.S. Federal Income Tax return for the
affiliated group (as that term is defined in Code Section 1504) of which Tenneco
International Holding Corp. is the common parent for Tax Periods ending after
December 31, 1999, and (c) Tax Returns for Consolidated or Combined State Income
Taxes which the Companies reasonably determine, in

                                      -18-

   19



accordance with Tenneco's past practices, are required to be filed by the
Companies or any of their Affiliates for Tax Periods ending after December 31,
1999.

              4.04  Tax Accounting Practices.

              (a) General Rule. Except as otherwise provided in this Section
4.04, any Tax Return for any Pre-Distribution Period or any Straddle Period, and
any Tax Return for any Post-Distribution Period to the extent items reported on
such Tax Return might reasonably affect items reported on any Tax Return for any
Pre-Distribution Period or any Straddle Period, shall be prepared in accordance
with past Tax accounting practices used with respect to the Tax Returns in
question (unless such past practices are no longer permissible under the Code or
other applicable Tax Law), and to the extent any items are not covered by past
practices (or in the event such past practices are no longer permissible under
the Code or other applicable Tax Law), in accordance with reasonable Tax
accounting practices selected by the Responsible Company.

              (b) Reporting of Transaction Tax Items. The tax treatment reported
on any Tax Return of Tax Items relating to the Transactions shall be consistent
with the treatment of such item in the IRS Ruling Letter. To the extent there is
a Tax Item relating to the Transactions which is not covered by the IRS Ruling
Letter, the Companies shall agree on the tax treatment of any such Tax Item
reported on any Tax Return. For this purpose, the tax treatment of such Tax
Items on a Tax Return by the Responsible Company with respect to such Tax Return
shall be agreed to by the other Company unless either (i) there is no reasonable
basis for such tax treatment, or (ii) such tax treatment is inconsistent with
the tax treatment contemplated in the Ruling Request. Such Tax Return shall be
submitted for review pursuant to Section 4.06(a), and any dispute regarding such
proper tax treatment shall be referred for resolution pursuant to Section 15,
sufficiently in advance of the filing date of such Tax Return (including
extensions) to permit timely filing of the return.

       4.05 Consolidated or Combined Returns. The Companies will elect and join,
and will cause their respective Affiliates to elect and join, in filing
consolidated, unitary, combined, or other similar joint Tax Returns, to the
extent each entity is eligible to join in such Tax Returns, if the Companies
reasonably determine that the filing of such Tax Returns is consistent with past
reporting practices, or in the absence of applicable past practices, will result
in the minimization of the net present value of the aggregate Tax to the
entities eligible to join in such Tax Returns.

       4.06   Right to Review Tax Returns.

              (a) General. The Responsible Company with respect to any Tax
Return shall make such Tax Return and related workpapers available for review by
the other Company, if requested, to the extent (i) such Tax Return relates to
Taxes for which the requesting party may be liable, (ii) such Tax Return relates
to Taxes for which the requesting party may be liable in whole or in part for
any additional Taxes owing as a result of adjustments to the amount of Taxes
reported on such Tax Return, (iii) such Tax Return relates to Taxes for which
the requesting party may have a

                                      -19-

   20



claim for Tax Benefits under this Agreement, or (iv) the requesting party
reasonably determines that it must inspect such Tax Return to confirm compliance
with the terms of this Agreement. The Responsible Company shall use its
reasonable best efforts to make such Tax Return available for review as required
under this paragraph sufficiently in advance of the due date for filing such Tax
Returns to provide the requesting party with a meaningful opportunity to analyze
and comment on such Tax Returns and have such Tax Returns modified before
filing, taking into account the party responsible for payment of the tax (if
any) reported on such Tax Return and the materiality of the amount of Tax
liability with respect to such Tax Return. The Companies shall attempt in good
faith to resolve any issues arising out of the review of such Tax Returns.

              (b) Execution of Returns Prepared by Other Party. In the case of
any Tax Return which is required to be prepared and filed by one Company under
this Agreement and which is required by law to be signed by the other Company
(or by its authorized representative), the Company which is legally required to
sign such Tax Return shall not be required to sign such Tax Return under this
Agreement if there is no reasonable basis for the tax treatment of any material
items reported on the Tax Return.

              4.07  Claims for Refund, Carrybacks, and Self-Audit Adjustments
("Adjustment Requests").

              (a) Consent Required for Adjustment Requests Related to
Consolidated or Combined Income Taxes. Neither Company shall be entitled to file
an Adjustment Request with respect to any Consolidated or Combined Income Tax
for a Pre-Distribution Period without the consent in writing of the other
Company (which consent shall not be unreasonably withheld or delayed). Any
Adjustment Request which the Companies consent to make under this Section 4.07
shall be prepared and filed by the Responsible Company under Section 4.02 for
the Tax Return to be adjusted. The Company requesting the Adjustment Request (if
not the Responsible Company) shall provide to the Responsible Company all
information required for the preparation and filing of such Adjustment Request
in such form and detail as reasonably requested by the Responsible Filing
Company.

              (b) Other Adjustment Requests Permitted. Nothing in this Section
4.07 shall prevent any Company or its Affiliates from filing any Adjustment
Request with respect to Income Taxes which are not Consolidated or Combined
Income Taxes or with respect to any Taxes other than Income Taxes. Any refund or
credit obtained as a result of any such Adjust ment Request (or otherwise) shall
be for the account of the person liable for the Tax under this Agreement.

              (c) Ordering of and Payment for Carrybacks.

                    (i) In the event that a member of the Packaging Group, on
the one hand, and a member of the Tenneco Group, on the other hand, are each
entitled to carryback a Tax Item to a Pre-Distribution Period, the respective
Tax Items shall be utilized under the rules of applicable

                                      -20-

   21



Tax Law (which shall be, in the case of Carrybacks to such Tax Periods of the
affiliated group of which Tenneco is the common parent, the rules contained in
Treasury Regulation Section 1.1502-21T).

                    (ii) Any Tax refund or other Tax Benefit resulting from the
Carryback of any member of one Group (the "Carryback Group") of any Tax Item
arising after the Distribution Date to a Pre-Distribution Period shall be for
the account of the Carryback Group (and in the event the Packaging Group is the
Carryback Group, Tenneco shall promptly pay to Packaging Company the amount of
such Tax refund or other Tax Benefit); provided, however, that if at the time of
the utilization of the Carryback Items of a member of the Carryback Group, a
member of the other Group (the "Other Group") possesses Carryback Tax Items
which, but for the ordering rule set forth in Section 4.07(c)(i), would have
been available to be utilized (the "Available Other Group Carryback") in lieu of
the Carryback Group's Tax Items, then (but only to the extent of the Available
Other Group Carryback) the Carryback Group shall not be entitled to payment of
the amount of such Tax refund or Tax Benefit until the earlier of (X) the date
on which a member of the Other Group claims the Available Other Group Carryback
on a Tax Return or (Y) the date on which a member of the Carryback Group would
have been able to utilize the Carryback had it not been claimed with respect to
the Pre-Distribution Period Tax Return.

                    (iii) In the event the Carryback of Tax Items of a member of
the Packaging Group, or the Tenneco Group, as the case may be, does not result
in a Tax refund, due to an offsetting Tax adjustment to a member of the Other
Group, then the Other Group shall promptly pay the amount of any decrease in Tax
liability resulting from the Carryback claim, provided, however, that in the
event the Other Group possesses Carryback Items which, but for the ordering
rules of Section 4.07(c)(i) would have been available to be utilized in lieu of
the Carryback Group's Tax Items, then (but only to the extent of the Available
Other Group Carryback), the Other Group shall not be required to pay the amount
of such decrease in Tax liability to the Carryback Group until the earlier of
(X) the date on which a member of the Other Group claims the Available Other
Group Carryback on a Tax Return or (Y) the date on which a member of the
Carryback Group would have been able to utilize the Carryback had it not been
claimed with respect to the Pre-Distribution Period Tax Return.

              (d) Payment of Refunds. Except as otherwise provided in Section
4.07(c), any refunds or other Tax Benefits received by any Company (or any of
its Affiliates) as a result of any Adjustment Request which are for the account
of another Company (or member of such other Company's Group) shall be paid by
the Company receiving (or whose Affiliate received) such refund or Tax Benefit
to such other Company in accordance with Section 6.

       The Company liable for such Tax will pay such amount to such Tax
       Authority on or before such Payment Date.

              (b) Computation and Payment of Packaging Company Liability. With
respect to the Consolidated or Combined State Income Tax Returns (excluding any

                                      -24-

   25



              5.05 Payment of Separate Company Taxes. Each Company shall pay, or
shall cause to be paid, to the applicable Tax Authority when due all Separate
Company Taxes owed by such Company or a member of such Company's Group.

              5.06 Indemnification Payments. If any Company (the "payor") is
required to pay to a Tax Authority a Tax that another Company (the "responsible
party") is liable for under this Agreement, the responsible party shall
reimburse the payor within 30 days of delivery by the payor to the responsible
party of an invoice for the amount due, accompanied by evidence of payment and a
statement detailing the Taxes paid and describing in reasonable detail the
particulars relating thereto. The reimbursement shall include interest on the
Tax payment computed at the Prime Rate based on the number of days from the date
of the payment to the Tax Authority to the date of reimbursement under this
Section 5.06.

       SECTION 6.   TAX BENEFITS.

              6.01  General Rule.

              (a) If a member of one Group receives a Tax refund with respect to
Taxes for which a member of the other Group is liable hereunder, the Company
receiving such Tax refund shall make a payment to the Company who is liable for
such Taxes hereunder within 30 days following receipt of the Tax refund in an
amount equal to such Tax refund, plus interest on such amount computed at the
Prime Rate based on the number of days from the date of receipt of the Tax
refund to the date of payment under this Section 6.01. Notwithstanding the
foregoing, any refund of withholding Tax received by Tenneco International
Holding Corporation ("TIHC") from the Swiss Tax Authority with respect to a
dividend payment from Alupak A.G. to TIHC in the approximate amount of SF 5.2
million shall be for the account of Packaging Company and Tenneco shall,
promptly following TIHC's receipt of such refund, cause such refund to be paid
to Packaging Company.

              (b) In the event one Group is reimbursed for its payment of a Tax
liability of the other Group, the amount of such reimbursement shall be computed
net of any Tax Benefit realized by the reimbursed Group as the result of payment
of the other Group's Tax liability.

              6.02 Adjustment of Tax Attributes. In the event that the Carryback
of Tax Items of one Group, or a Tax adjustment attributable to such Group under
the terms of this Agreement, results in the disallowance or limitation of Tax
attributes (including Tax credits, deductions and similar items) claimed on the
Tax Return as filed, the Carryback Group shall be responsible for any increase
in Tax liability resulting from the disallowance or limitation of such Tax
attributes; provided, however, that in the event the disallowance or limitation
of Tax attributes results in a Tax Benefit resulting from the use of such Tax
attributes in another Tax Period, such Tax Benefit shall be deemed to be for the
account of the Carryback Group for purposes of this Agreement.

                                      -25-

   26



              6.03 Correlative Adjustments. If, upon examination by any Tax
Authority of any Tax Return including a member of the Tenneco Group or Packaging
Group for any Tax Period, an item of deduction, credit or expense is disallowed
for which Tenneco is or may be liable for Taxes hereunder (or an item of income
is required to be recognized on a Tax Return which was not reported on such Tax
Return), in either such case resulting in a tax detriment suffered by the
Tenneco Group, and such disallowance (or recognition) results in a Tax Benefit
to the Packaging Group (with respect to that Tax Period or another Tax Period),
then Packaging shall pay to Tenneco the amount of such Tax Benefit (but in no
case to exceed the corresponding tax detriment). Any payment required to be made
hereunder shall be made when such Tax Benefit is realized in the form of an
actual reduction in Tax (which shall be computed by comparing the Tax which
would have been owed by Packaging but for the item giving rise to the Tax
Benefit with the Tax owed by Packaging taking such item into account). The
provisions of this Section 6.03 shall apply mutatis mutandis where an item of
deduction, credit or expense is disallowed for which Packaging is or may be
liable for Taxes hereunder (or an item of income is required to be recognized on
a Tax Return which was not reported on such Tax Return), as they apply where the
Tenneco Group suffers such a tax detriment. For avoidance of doubt, any payment
required to be made by Tenneco to the Packaging Group under this Section 6.03
shall, to the extent applicable, be deemed as an offset to amounts owing by
Packaging to Tenneco under Section 2.02 hereof.

       SECTION 7.   ASSISTANCE AND COOPERATION.

              7.01 General. After the Distribution Date, each of the Companies
shall cooperate (and cause their respective Affiliates to cooperate) with each
other and with each other's agents, including accounting firms and legal
counsel, in connection with Tax matters relating to the Companies and their
Affiliates including (i) preparation and filing of Tax Returns, (ii) determin
ing the liability for and amount of any Taxes due (including estimated Taxes) or
the right to and amount of any refund of Taxes, (iii) examinations of Tax
Returns, and (iv) any administrative or judicial proceeding in respect of Taxes
assessed or proposed to be assessed. Such cooperation shall include making all
information and documents in their possession relating to the other Companies
and their Affiliates available to such other Companies as provided in Section 8.
Each of the Companies shall also make available to each other, as reasonably
requested and available, personnel (including officers, directors, employees and
agents of the Companies or their respective Affiliates) responsible for
preparing, maintaining, and interpreting information and documents relevant to
Taxes, and personnel reasonably required as witnesses or for purposes of
providing information or documents in connection with any administrative or
judicial proceed ings relating to Taxes. Any information or documents provided
under this Section 7 shall be kept confidential by the Company receiving the
information or documents, except as may otherwise be necessary in connection
with the filing of Tax Returns or in connection with any administrative or
judicial proceedings relating to Taxes.

              7.02 Income Tax Return Information. Each Company will provide to
the other Company information and documents relating to their respective Groups
required by the other Company to prepare Tax Returns. The Responsible Company
shall determine a reasonable

                                      -26-

   27



compliance schedule for such purpose in accordance with Tenneco's past
practices. Any additional information or documents the Responsible Company
requires to prepare such Tax Returns will be provided in accordance with past
practices, if any, or as the Responsible Company reasonably requests and in
sufficient time for the Responsible Company to file such Tax Returns timely.

       SECTION 8.   TAX RECORDS.

              8.01 Retention of Tax Records. Except as provided in Section 8.02,
each Company shall preserve and keep all Tax Records exclusively relating to the
assets and activities of its Group for Pre-Distribution Tax Periods, and Tenneco
shall preserve and keep all other Tax Records relating to Taxes of the Groups
for Pre-Distribution Tax Periods, for so long as the contents thereof may become
material in the administration of any matter under the Code or other applicable
Tax Law, but in any event until the later of (i) the expiration of any
applicable statutes of limitation, and (ii) seven years after the Distribution
Date. If, prior to the expiration of the applicable statute of limitation and
such seven-year period, a Company reasonably determines that any Tax Records
which it is required to preserve and keep under this Section 8 are no longer
material in the administration of any matter under the Code or other applicable
Tax Law, such Company may dispose of such records upon 90 days prior notice to
the other Company. Such notice shall include a list of the records to be
disposed of describing in reasonable detail each file, book, or other record
accumulation being disposed. The notified Company shall have the opportunity, at
its cost and expense, to copy or remove, within such 90-day period, all or any
part of such Tax Records.

              8.02 State Income Tax Returns. Tax Returns with respect to State
Income Taxes and workpapers prepared in connection with preparing such Tax
Returns shall be preserved and kept, in accordance with the guidelines of
Section 8.01, by the Company responsible for preparing and filing the applicable
Tax Return.

              8.03 Access to Tax Records. The Companies and their respective
Affiliates shall make available to each other for inspection and copying during
normal business hours upon reasonable notice all Tax Records in their possession
to the extent reasonably required by the other Company in connection with the
preparation of Tax Returns, audits, litigation, or the resolution of items under
this Agreement.

       SECTION 9.   TAX CONTESTS.

              9.01 Notice. Each of the parties shall provide prompt notice to
the other party of any pending or threatened Tax audit, assessment or proceeding
or other Tax Contest of which it becomes aware related to Taxes for Tax Periods
for which it is indemnified by the other party hereunder. Such notice shall
contain factual information (to the extent known) describing any asserted Tax
liability in reasonable detail and shall be accompanied by copies of any notice
and other documents received from any Tax Authority in respect of any such
matters. If an indemni-

                                      -27-

   28



fied party has knowledge of an asserted Tax liability
with respect to a matter for which it is to be indemnified hereunder and such
party fails to give the indemnifying party prompt notice of such asserted Tax
liability, then (i) if the indemnifying party is precluded from contesting the
asserted Tax liability in any forum as a result of the failure to give prompt
notice, the indemnifying party shall have no obligation to indemnify the
indemnified party for any Taxes arising out of such asserted Tax liability, and
(ii) if the indemnifying party is not precluded from contesting the asserted Tax
liability in any forum, but such failure to give prompt notice results in a
monetary detriment to the indemnifying party, then any amount which the
indemnifying party is otherwise required to pay the indemnified party pursuant
to this Agreement shall be reduced by the amount of such detriment.

              9.02  Control of Tax Contests.

              (a) Separate Company Taxes. In the case of any Tax Contest with
respect to any Separate Company Tax, the Company having liability for the Tax
shall have exclusive control over the Tax Contest, including exclusive authority
with respect to any settlement of such Tax liability.

              (b) Consolidated or Combined Income Taxes. In the case of any Tax
Contest with respect to any Consolidated or Combined Income Tax, (i) Tenneco
shall control the defense or prosecution of the portion of the Tax Contest
directly and exclusively related to any Tenneco Adjustment, including settlement
of any such Tenneco Adjustment, and (ii) Packaging Company shall control the
defense or prosecution of the portion of the Tax Contest directly and
exclusively related to any Packaging Adjustment, including any settlement of any
Packaging Adjustment, and (iii) the two-person committee (the "Tax Contest
Committee"), comprised of one person selected by Packaging Company (as
designated in writing to Tenneco) and one person selected by Tenneco (as
designated in writing to Packaging Company) shall control the defense or prosecu
tion of Joint Adjustments and any and all administrative matters not directly
and exclusively related to any Tenneco Adjustment. Each person serving on the
Tax Contest Committee shall continue to serve unless and until he or she is
replaced by the party designating such person. Any and all matters to be decided
by the Tax Contest Committee shall require the unanimous approval of both
persons serving on the committee. In the event the Tax Contest Committee shall
be deadlocked on any matter, the provisions of Section 15 of this Agreement
shall apply. A Company shall not agree to any Tax liability for which another
Company may be liable under this Agreement, or compromise any claim for any Tax
Benefit which another Company may be entitled under this Agreement, without such
other Company's written consent (which consent may be given or withheld at the
sole discretion of the Company from which the consent would be required).

       SECTION 10. EFFECTIVE DATE; TERMINATION OF PRIOR INTERCOMPANY TAX
ALLOCATION AGREEMENTS. This Agreement shall be effective on the Distribution
Date. Immediately prior to the close of business on the Distribution Date
Tenneco shall cause all Prior Intercompany Tax Allocation Agreements to be
terminated with respect to Packaging Company and its Affiliates.

                                      -28-

   29



Upon such termination, no further payments by or to Tenneco or by or to
Packaging Company, with respect to such agreements shall be made, and all other
rights and obligations resulting from such agreements between the Companies and
their Affiliates shall cease at such time.

       SECTION 11. NO INCONSISTENT ACTIONS. Each of the Companies covenants and
agrees that it will not take any action, and it will cause its Affiliates to
refrain from taking any action, which is inconsistent with the Tax treatment of
the Transactions as contemplated in the Ruling Request (any such action is
referred to in this Section 11 as a "Prohibited Action"), unless such Prohibited
Action is required by law, or the person acting has obtained the prior written
consent of each of the other parties (which consent shall not be unreasonably
withheld). With respect to any Prohibited Action proposed by a Company (the
"Requesting Party"), the other party (the "Requested Party") shall grant its
consent to such Prohibited Action if the Requesting Party obtains a ruling with
respect to the Prohibited Action from the Internal Revenue Service or other
applicable Tax Authority that is reasonably satisfactory to each of the
Requested Party (except that the Requesting Party shall not submit any such
ruling request if a Requested Party deter mines in good faith that filing such
request might have a materially adverse effect upon such Requested Party).
Without limiting the foregoing:

              (a) No Inconsistent Plan or Intent. Packaging Company and Tenneco
each represent and warrant that neither it nor any of its Affiliates has any
plan or intent to take any action which is inconsistent with any factual
statements or representations in the Ruling Request. Regardless of any change in
circumstances, Packaging Company and Tenneco each covenant and agree that it
will not take, and it will cause its Affiliates to refrain from taking, any such
inconsistent action on or before the last day of the calendar year ending after
the second anniversary of the Distribution Date, other than as permitted in this
Section 11.

              (b) 355(e) Covenant. Without in any manner limiting paragraph (a)
above and unless the Requesting Party obtains a ruling as provided above in the
first paragraph of this Section 11, each of Packaging Company and Tenneco
covenants and agrees that it will not enter into any negotiations, agreement or
arrangements with respect to transactions or events (includ ing stock issuances,
option grants, capital contributions or acquisitions, but not including the
Transactions), which may cause the Distribution to be treated as part of a plan
pursuant to which one or more persons acquire directly or indirectly Packaging
Company or Tenneco stock, as the case may be, representing a "50-percent or
greater interest" within the meaning of Section 355(d)(4) of the Code.

              (c) Amended or Supplemental Rulings. Each of the Companies
covenants and agrees that it will not file, and it will cause its Affiliates to
refrain from filing, any amendment or supplement to the Ruling Request
subsequent to the Distribution Date without the consent of the other Company,
which consent shall not be unreasonably withheld or delayed.

       SECTION 12.         SURVIVAL OF OBLIGATIONS.  The representations,
warranties, covenants and agreements set forth in this Agreement shall be
unconditional and absolute and shall remain in effect without limitation as to
time.

       SECTION 13.         EMPLOYEE MATTERS.  Each of the Companies agrees to
utilize, or cause its Affiliates to utilize, the alternative procedure
set forth in respect to wage reporting set forth in Revenue Procedure 96-60,
1996-2 C.B. 399, with respect to wage reporting.

       SECTION 14.         TREATMENT OF PAYMENTS; TAX GROSS UP.

              14.01 Treatment of Tax Indemnity and Tax Benefit Payments.  In
the absence of any change in tax treatment under the Code or other applicable
Tax Law,

              (a) any Tax indemnity payments made by a Company under Section 5
shall be reported for Tax purposes by the payor and the recipient as
distributions or capital contributions, as appropriate, occurring immediately
before the distribution of all of the outstanding stock of Packaging Company to
Tenneco shareholders on the Distribution Date, and

              (b) any Tax Benefit payments made by a Company under Section 6,
shall be reported for Tax purposes by the payor and the recipient as
distributions or capital contributions, as appropriate, occurring immediately
before the distribution of all of the outstanding stock of Packaging Company to
Tenneco shareholders on the Distribution Date.

              14.02 Tax Gross Up. If notwithstanding the manner in which Tax
indemnity payments and Tax Benefit payments were reported, there is an
adjustment to the Tax liability of a Company as a result of its receipt of a
payment pursuant to this Agreement, such payment shall be appropriately adjusted
so that the amount of such payment, reduced by the amount of all Income Taxes
payable with respect to the receipt thereof (but taking into account all
correlative Tax Benefits resulting from the payment of such Income Taxes), shall
equal the amount of the payment which the Company receiving such payment would
otherwise be entitled to receive pursuant to this Agreement.

              14.03 Interest Under This Agreement. Anything herein to the
contrary notwithstand ing, to the extent one Company ("indemnitor") makes a
payment of interest to another Company ("indemnitee") under this Agreement with
respect to the period from the date that the indemnitee made a payment of Tax to
a Tax Authority to the date that the indemnitor reimbursed the indemnitee for
such Tax payment, or with respect to the period from the date that the
indemnitor received a Tax Benefit to the date indemnitor paid the Tax Benefit to
the indemnitee, the interest payment shall be treated as interest expense to the
indemnitor (deductible to the extent provided by law) and as interest income by
the indemnitee (includible in income to the extent provided by law). The amount
of the payment shall not be adjusted under Section 14.02 to take into account
any associated Tax Benefit to the indemnitor or increase in Tax to the
indemnitee.

       SECTION 15. DISAGREEMENTS. If after good faith negotiations the parties
cannot agree on the application of this Agreement to any matter, then the matter
will be referred to a nationally recognized accounting firm acceptable to each
of the parties (the "Accounting Firm"). The Accounting Firm shall furnish
written notice to the parties of its resolution of any such disagree ment as
soon as practical, but in any event no later than 45 days after its acceptance
of the matter for resolution. Any such resolution by the Accounting Firm will be
conclusive and binding on all parties to this Agreement. In accordance with
Section 17, each party shall pay its own fees and expenses (including the fees
and expenses of its representatives) incurred in connection with the referral of
the matter to the Accounting Firm. All fees and expenses of the Accounting Firm
in connection with such referral shall be shared equally by the parties affected
by the matter.

       SECTION 16. LATE PAYMENTS. Any amount owed by one party to another party
under this Agreement which is not paid when due shall bear interest at the Prime
Rate plus two percent, compounded semiannually, from the due date of the payment
to the date paid. To the extent interest required to be paid under this Section
16 duplicates interest required to be paid under any other provision of this
Agreement, interest shall be computed at the higher of the interest rate
provided under this Section 16 or the interest rate provided under such other
provision.

       SECTION 17. EXPENSES. Except as provided in Section 15, each party and
its Affiliates shall bear their own expenses incurred in connection with
preparation of Tax Returns, Tax Contests, and other matters related to Taxes
under the provisions of this Agreement.

       SECTION 18. SPECIAL RULES FOR DETERMINING MEMBERS OF GROUPS.  For
purposes of this Agreement, the following special rules shall apply for
determining the members of the Packaging Group:

                    (a) Former Affiliates of Packaging Group. The Packaging
Group shall be deemed to include any corporation which (1) was a member of the
affiliated group (as defined in Code Section 1504(a), but treating all
corporations as "includable corporations" for purposes of such Code Section) of
which Tenneco is (or Old Tenneco was) the common parent, (2) was included in the
"packaging," "specialty packaging" or "paperboard packaging" segments for
purposes of segment reporting in Tenneco's (or Old Tenneco's) Annual Reports on
Form 10-K and (3) was sold, transferred, otherwise disposed of, or discontinued
prior to the date hereof. Any entity substantially all of the assets and
liabilities of which have been transferred to a member of the Packaging Group
(e.g., by a statutory merger) shall be treated as a member of the Packaging
Group. For example, Tenneco Packaging Specialty and Consumer Products Inc., a
Delaware corporation, shall, by virtue of its liquidation into Tenneco Packaging
Inc., be treated as a member of the Packaging Group. Similarly, Tenneco United
Kingdom Holdings Limited shall be treated as a member of the Packaging Group.

              19.03 Waiver. No failure by any party to insist upon the strict

expressly required in this Agreement, a party shall not be required to exhaust
all remedies available under other agreements or at law or equity before
recovering under the remedies provided in this Agreement. Subject to any
limitations provided in this Agreement (for example, the limitation on filing
