Item 2.  Acquisition or Disposition of Assets.

     (a)  On December 1, 1997,  Millennium Chemicals Inc. (the "Registrant") and
          Lyondell  Petrochemical Company ("Lyondell") completed a joint venture
          transaction  to  form  Equistar  Chemicals,  LP  (the  "Partnership"),
          combining  both  companies'  olefins  and  polymers   businesses.   In
          connection  with  the  joint  venture   transaction,   the  Registrant
          contributed   substantially   all  of  the   assets   comprising   its
          polyethylene  and related  products,  performance  polymers  and ethyl
          alcohol   businesses  other  than  the  related  accounts   receivable
          (collectively,  the "Millennium  Contributed  Business") to Millennium
          Petrochemicals LP LLC ("Millennium LP"), a wholly-owned  subsidiary of
          the Registrant,  which in turn contributed the Millennium  Contributed
          Business to the  Partnership.  In  exchange  for the  contribution  of
          assets  to  the   Partnership,   (i)   Millennium  LP  and  Millennium
          Petrochemicals  GP LLC, a wholly-owned  subsidiary of the  Registrant,
          received  an  aggregate  43%  interest  in the  Partnership,  (ii) the
          Registrant  received  $750  million  in cash from the  Partnership  in
          repayment of certain  indebtedness,  and (iii) the Partnership assumed
          certain  other  liabilities  related  to  the  Millennium  Contributed
          Business. In addition, the Registrant expects to realize approximately
          $250 million over the next several  months from the  collection of its
          retained accounts receivable.  Millennium America Inc., a wholly-owned
          subsidiary  of  the   Registrant,   has  guaranteed  $750  million  of
          indebtedness  of  the  Partnership.   The  consideration  received  in
          exchange for the Millennium  Contributed Business was determined based
          upon  arms-length  negotiations  between the  Registrant and Lyondell,
          which simultaneously  contributed certain assets to the Partnership in
          exchange for an aggregate 57% interest in the  Partnership.  The joint
          venture  transaction  is  described  in  detail  in  the  Joint  Proxy
          Statement  (the "Joint Proxy  Statement")  filed by the Registrant and
          Lyondell with the  Securities  and Exchange  Commission on October 17,
          1997; the Joint Proxy Statement is  incorporated  herein by reference.
          The Registrant's  stockholders  approved such transaction at a special
          meeting held on November 20, 1997.

                   (ii) All  obligations  under purchase  orders accepted by the

                   (x)   The  long-term  liabilities  set  forth  on  Schedule

         Partnership pursuant to the terms of this Agreement.

The  liabilities and  obligations  assumed by the  Partnership  pursuant to this
Section are  sometimes  hereinafter  referred to  collectively  as the  "Assumed
Liabilities."

         (b)  On  the  Closing  Date,  the  Partnership  shall  deliver  to  the
Contributor an instrument of assumption of the Assumed Liabilities substantially
in the form attached hereto as Exhibit F (the "Assumption Agreement").

         2.6  Excluded Liabilities.  Except as otherwise  expressly  provided in
this  Agreement  (including,without  limitation,  Sections  6.2 and  7.2) or the
Assumption  Agreement,  the Partnership is assuming only the Assumed Liabilities
and is not assuming any other  liability or obligation of the Contributor or any
Affiliate thereof, of whatever nature, whether presently in existence or arising
hereafter,  whether known or unknown, or whether absolute or contingent, and all
such other  liabilities  and  obligations of the  Contributor  and any Affiliate
thereof  that are not  Assumed  Liabilities  shall  be  retained  by and  remain
obligations  and  liabilities  of the  Contributor  or such  Affiliate (all such
liabilities  and   obligations   being  herein  referred  to  as  the  "Excluded
Liabilities"), including the following:

         (i)    Any Pre-Closing  Contingent Liability  that  is  not an  Assumed
                Liability;

         (ii)   any obligation or liability relating to the Excluded Assets; and

         (iii)  any  obligation  (A)  for  the  payment  of  severance  benefits
                to  employees  of the  Contributor  or any of its  Affiliates
                except as set forth in Sections  2.8(b) or (c), or (B)  
                attributable to Contributor's  or any of its  Affiliates'  
                employment of any employee, agent or independent contractor 
                prior to the Closing Date.

         2.7    Master Intellectual Property Agreement

         On the Closing Date, the Partnership and Contributor  shall execute and
deliver a master  intellectual  property  agreement  (the  "Master  Intellectual
Property  Agreement")  in  substantially  the form attached  hereto as Exhibit G
providing, among other things, the following:

         (a)  Non-exclusive,  royalty-free  licenses to the  Partnership  of any
Intellectual Property and Trademarks used, contemplated for use or that could be
used,  in the  Contributed  Business  that is not  conveyed  to the  Partnership
pursuant to Section 2.1.

         (b)  Non-exclusive,  royalty-free  licenses to the  Contributor  or its
Affiliates of any Contributed  Intellectual Property acquired by the Partnership
pursuant to Section 2.1 of this  Agreement  used,  contemplated  for use or that
could be used in the business of the Contributor or its Affiliates.

         (c) The  assignment  of the  Contributed  Intellectual  Property to the
Partnership.

         2.8  Employee Matters.  If the Closing  Date occurs prior to January 1,
1998, the effective employment date shall be January 1, 1998 and the Contributor
and the Partnership  shall enter into an agreement to provide employee  services
to the Partnership through December 31, 1997.

         (a) At or prior to the Closing,  the Partnership  shall determine which
employees of the Contributor or any Affiliate thereof will be offered employment
by the Partnership. Any such employee that accepts such offer is herein called a
"Partnership Employee." Partnership Employees shall be employed effective on (i)
January 1,  1998,  or (ii) if the  Closing  Date is after  January 1, 1998,  the
Closing Date.

         (b) If, within six months after the Closing Date or in  anticipation of
Closing,  the Contributor or any Affiliate  thereof  terminates  (other than for
cause) the  employment  of any  employee  of the  Contributor  or any  Affiliate
thereof who is primarily  associated with the Assets or the Contributed Business
but who does not become a Partnership Employee, then the Partnership will pay to
the  Contributor  an  amount  equal to the Basic  Severance  to the  extent  the
Contributor or any Affiliate  thereof pays the Basic Severance to such employee.
"Basic  Severance"  means two weeks of base pay for each full year of service by
the employee with the  Contributor or any Affiliate (or  predecessors of either,
to the extent service therefor is credited by the Contributor),  subject to a 52
week maximum and a 12 week minimum; provided,  however, that with respect to any
employee who has an employment  agreement that contains provisions providing for
one or more  payments  in the event of a change in control  of the  Contributor,
"Basic  Severance"  means  up  to 52  weeks  of  base  pay  notwithstanding  the
employee's years of service.

         (c) Any  Partnership  Employee  whose  employment  is terminated by the
Partnership  (other than for cause)  within six months  after the  Closing  Date
shall be entitled to receive a severance  benefit from the Partnership  equal to
the Basic  Severance  (which,  for purposes of calculating  service time,  shall
include the employee's time of service with the  Contributor,  its  predecessors
(to  the  extent  service  therefor  is  credited  by the  Contributor)  and the
Partnership).

         (d) Any  employees  of the  Contributor  that the  Partnership  and the
Contributor  agree are  necessary  for the orderly  transfer of the  Contributed
Business  to the  Partnership  but who will  not  become  Partnership  Employees
("Transition  Employees")  shall be compensated by the  Contributor on terms and
conditions  and for a  duration  to be agreed  upon by the  Partnership  and the
Contributor. The Partnership shall reimburse the Contributor for any such agreed
upon   compensation,   including  payroll  taxes,   benefit  costs  and  workers
compensation  premiums and claims, paid by the Contributor to or with respect to
any Transition Employee.

         (e) If any employee of the  Contributor  is eligible for and  receiving
short  term  disability  benefits  or sick  pay as of the  Closing  Date and the
Partnership  has offered  such  employee  employment  by the  Partnership,  that
employee  shall become  employed by the  Partnership  (and become a  Partnership
Employee for purposes of this Section 2.8) upon  eligibility to return to active
employment  with  the  Contributor  under  the  applicable   conditions  of  the
Contributor's  short  term  disability  benefits  or sick pay plan.  Partnership
employment  shall not be  effective  until  the  Contributor  verifies  that the
employee has satisfied the conditions  (if any) to return to active  employment.
Until such time as such employee becomes a Partnership  Employee the Contributor
shall continue to bear all costs and expenses associated with such employee.

         (f) Neither the  Contributor  nor any of its Affiliates  shall,  at any
time prior to 60 days after the Closing Date,  effect a "plant closing" or "mass
layoff",  as those terms are  defined in the Worker  Adjustment  and  Retraining
Notification  Act of 1988 ("WARN"),  affecting in whole or in part any facility,
site of employment,  operating unit or employee of the Contributor or any of its
Affiliates  without  complying  fully with the  notice and all other  applicable
requirements of WARN.

         (g) In connection  with the  development by the  Partnership of benefit
plans  and  programs  for  Partnership  Employees  as  provided  in  the  Master
Transaction Agreement,  (i) the Contributor may direct the trustee of any of its
employee  plans to  transfer  assets and  liabilities  in those  employee  plans
associated  with the accrued  benefits of Partnership  Employees to a comparable
Partnership  benefit plan in which the Partnership  Employees  participate,  and
(ii) the  Contributor  or any of its  Affiliates  may direct the  trustee of its
grantor trust to transfer  assets and  liabilities  relating to any accounts for
Partnership Employees under an executive deferral plan to a trust established by
the Partnership to provide  benefits under a comparable  non-qualified  deferred
compensation plan;  provided,  however,  with respect to (i) and (ii) above, the
assets associated with any such plans, as of the Closing Date, are not less than
the  liabilities  associated  therewith as determined by the  Partnership  and a
trust to trust  transfer  of  assets  does not  result in a  taxable  event.  In
connection with the development and  implementation  of such plans and programs,
the  Partnership  agrees,  for purposes of calculating  service time, to include
each employee's time of service with the  Contributor,  its predecessors (to the
extent service therefor is credited by the Contributor) or the Partnership.  The
Partnership  will accept  sponsorship of the Assumed Plan as soon as practicable
after the Closing Date and the Contributor shall make all necessary governmental
filings in  connection  therewith  on a timely  basis.  In  connection  with the
transfer of the  sponsorship  of the Assumed Plan, the  Partnership  may require
such representations  concerning the Assumed Plan as the Partnership  reasonably
determines  are  necessary,  including,  that the  assets  are not less than the
liabilities and no Consents from the union are necessary for such transfer.

         (h) To the extent that the Partnership adopts benefit plans or policies
that contemplate the provision of  post-retirement  life and medical benefits to
the  Partnership  Employees,  the  Partnership  shall record and  recognize,  in
accordance with GAAP, the associated liability for providing the post-retirement
life and medical benefits to the Partnership Employees.

          2.9   Joint Contracts.

         (a) Any Contributed  Contracts  contributed to the Partnership pursuant
to Section 2.1 that relate  principally  to the  Contributed  Business  but also
relate to the business (other than the Contributed  Business) of the Contributor
or its Affiliates  will be made available to the  Contributor and its Affiliates
by the  Partnership  pursuant  to  the  Shared  Services  Agreements  and  other
arrangements by which the Contributor and its Affiliates will enjoy the benefits
of such  Contributed  Contracts as they relate to their business (other than the
Contributed Business) on the same terms and conditions as the Partnership.

         (b) Any Contracts that relate  principally to the business  (other than
the  Contributed  Business) of the Contributor or its Affiliates but also relate
to the  Contributed  Business will be made  available to the  Partnership by the
Contributor or its  Affiliates  pursuant to the Shared  Services  Agreements and
other  arrangements  by which the  Partnership  will enjoy the  benefits of such
Contracts  as they  relate to the  Contributed  Business  on the same  terms and
conditions as the Contributor or its Affiliates.


                                    SECTION 3
                REPRESENTATIONS AND WARRANTIES OF THE CONTRIBUTOR
                -------------------------------------------------

         Except  as  set  forth  on  Schedule  3 or  in  the  SEC  Reports,  the
Contributor represents and warrants to the Partnership as follows:

         3.1  Due Organization:  Good Standing and Power.  The  Contributor is a
corporation duly organized, validly existing and in good standing under the laws
of the  Commonwealth  of Virginia and has the  corporate  power and authority to
own, lease and operate the properties to be contributed hereunder and to conduct
the  Contributed  Business  as now  conducted  by it.  The  Contributor  has all
corporate  power and authority to enter into this  Agreement and the  Assignment
and  Assumption   Agreements  and  to  perform  its  obligations  hereunder  and
thereunder.  The  Contributor  is duly  authorized,  qualified or licensed to do
business  as a foreign  corporation,  and is in good  standing,  in the State of
Texas  and in each of the  other  jurisdictions  in which  its  right,  title or
interest  in or to  any  of the  Assets  held  by  it,  or  the  conduct  of the
Contributed  Business  by it,  requires  such  authorization,  qualification  or
licensing,  except  where the  failure to so  qualify or to be in good  standing
would not reasonably be expected to have a Material Adverse Effect.

         3.2      Authorization  and  Validity  of  Agreements.  The  execution,
delivery and  performance of this Agreement and the other Related  Agreements by
the Contributor  and the  consummation  by it of the  transactions  contemplated
hereby and thereby  have been duly  authorized  by the Board of Directors of the
Contributor.  Except to the extent  heretofore  obtained,  no other corporate or
stockholder action is necessary for the authorization,  execution,  delivery and
performance  by  the  Contributor  of  this  Agreement  and  the  other  Related
Agreements  and  the   consummation  by  the  Contributor  of  the  transactions
contemplated hereby or thereby.  This Agreement and the other Related Agreements
have been duly executed and delivered by the Contributor  and constitute  legal,
valid and binding obligations of the Contributor, enforceable in accordance with
their  terms,  except  as the same may be  limited  by  bankruptcy,  insolvency,
reorganization,  moratorium  and other laws relating to or affecting  creditors'
rights generally and by general equity principles.

         3.3   No Consents  Required:  No Conflict with Instruments to which the
Contributor  is a  Party.  The  execution,  delivery  and  performance  of  this
Agreement  and  the  other  Related  Agreements  by  the  Contributor  or by any
Affiliate of the Contributor that is a party thereto and the consummation by the
Contributor or any such Affiliate of the transactions  contemplated  thereby (i)
will not require any Consent except for such Consents the failure of which to be
obtained or made,  would not in the  aggregate  reasonably be expected to have a
Material  Adverse Effect;  and (ii) will not violate (with or without the giving
of  notice or the lapse of time or both),  or  conflict  with,  or result in the
breach or  termination  of any provision of, or constitute a default  under,  or
result  in  the  acceleration  of the  performance  of  the  obligations  of the
Contributor  or any such  Affiliate  under,  or  result  in the  creation  of an
Encumbrance  upon any Assets or a portion of the Contributed  Business  pursuant
to, the  charter or by-laws of the  Contributor  or any such  Affiliate,  or any
indenture,  mortgage,  deed of  trust,  lease,  licensing  agreement,  contract,
instrument or other  agreement to which the Contributor or any such Affiliate is
a party or by which the  Contributor  or any such Affiliate or any of the Assets
held by the  Contributor  or any  such  Affiliate  is  bound,  except  for  such
violations,  conflicts,  breaches,  terminations,   defaults,  accelerations  or
Encumbrances  which would not in the aggregate  reasonably be expected to have a
Material Adverse Effect.

         3.4       Employee Benefits.

         (a)  (i)  Each  of  the  Contributor's   Defined  Benefit  and  Defined
         Contribution  Pension Plans covering employees  ("Employee Plan") is in
         substantial compliance with applicable  requirements  prescribed by any
         and all Legal  Requirements,  including,  but not  limited to the Code,
         except  for  violations  the  occurrence  of  which  would  not  in the
         aggregate  reasonably  be expected to have a Material  Adverse  Effect.
         Each  Employee  Plan that is intended  to be  qualified  under  Section
         401(a) of the Code currently has a favorable  determination letter from
         the  Internal  Revenue  Service as to that Plan's  qualification  under
         Section  401(a) of the Code and nothing has occurred  since the date of
         such letter that could reasonably be expected to cause the loss of such
         qualification.

                   (ii) The Contributor has in all material  respects  performed
         all  obligations  required to be performed by it under ERISA,  the Code
         and any other applicable Legal Requirements and under the terms of each
         Employee  Plan,  except such failures to perform which would not in the
         aggregate reasonably be expected to have a Material Adverse Effect. The
         Contributor  has  received no written  notice of the  existence  of any
         material  default or  violation by any other party of any of such Legal
         Requirements,  terms or requirements  applicable to any of the Employee
         Plans.

                   (iii) Other than routine claims for benefits, the Contributor
         has not received any written notice of any pending  material  claims or
         lawsuits  which have been  asserted  or  instituted  against any of the
         Employee  Plans,  the assets of the trust or funds  under the  Employee
         Plans,  the sponsor or  administrator  of any of the Employee Plans, or
         against any fiduciary of any of the Employee  Plans with respect to the
         operation of such Plan.

                   (iv) The  Contributor  has not received any written notice of
         any pending  investigation or pending enforcement action by the Pension
         Benefit  Guaranty  Corporation,  the Department of Labor,  the Internal
         Revenue  Service  or any other  Authority  with  respect  to any of the
         Employee Plans.

                   (v) All contributions  required to be made under the terms of
         the  Contributor's  Employee  Plans have been timely made.  No Employee
         Plan has an  "accumulated  funding  deficiency"  (within the meaning of
         section 412 of the Code or Section 402 of ERISA).

         (b) All of the  Contributor's  "group health plans" (within the meaning
of Code Section  5000(b)(1))  have been operated in substantial  compliance with
the group health plan continuation coverage requirements of Section 4980B of the
Code and  Sections  601  through 608 of ERISA,  Title XXII of the Public  Health
Service Act and the provisions of the Social Security Act.
         (c) There has been no act or omission by the Contributor that has given
rise to or may give rise to material fines, penalties, taxes, or related charges
under Section  502(c),  (i) or (l) or Section 4071 of ERISA or Chapter 43 of the
Code or the  imposition of a lien  pursuant to Sections  401(a)(29) or 412(n) of
the Code or pursuant to ERISA.

         3.5  Title to Assets; Absence of Liens and Encumbrances; Leases.

         (a) The  Contributor  has good and  marketable  title to all of the Fee
Interests described in the Deeds, free and clear of all Encumbrances, except (i)
those  exceptions  contained in the Deeds,  (ii) liens for current taxes not yet
due and  payable  and  mechanics  and  similar  statutory  liens  arising in the
ordinary  course of business,  (iii) liens of employees and laborers for current
wages  not  yet  due;  (iv)  building,  zoning  and  health  regulations  of the
jurisdictions  in which the Assets are located;  and (v) such  imperfections  of
title, easements and Encumbrances, if any, as do not in the aggregate materially
detract  from the value or  materially  interfere  with the use of the Assets as
they are currently  being used or as otherwise  would not reasonably be expected
to have a Material Adverse Effect.

         (b) The  Contributor  is the sole lessee  under the Leases and the sole
party entitled to the Leasehold interests in favor of the lessee thereunder, and
the sole owner of the  improvements  situated on the Leased  Premises,  free and
clear of all Encumbrances affecting the Leaseholds except such Encumbrances,  if
any, as do not in the aggregate  materially detract from the value or materially
interfere  with the use of the Assets or as otherwise  would not  reasonably  be
expected  to  have a  Material  Adverse  Effect.  Neither  Contributor  nor  any
Affiliate  thereof has  received  from or  delivered  to the  lessors  under the
Leaseholds  any written  notice of  termination  or threat of termination of the
respective Leaseholds.  True and complete copies of all written lease agreements
(including any written  amendments or modifications  thereof)  constituting,  or
evidencing the terms of, the Leaseholds have been delivered to the  Partnership.
No material  default or event of default on the part of the  Contributor nor any
Affiliate  thereof under the provisions of any of the  Leaseholds,  and no event
that with the giving of notice or passage of time or both would  constitute such
default or event of default on the part of the Contributor,  has occurred (which
default or event of default has not been cured). Neither the Contributor nor any
Affiliate  thereof has  received  any written  notice from any lessor  under any
Leasehold,  that any  material  default  or event of  default on the part of the
Contributor or such Affiliate as lessee under the provisions of any  Leaseholds,
or that any event  that with the  giving  of notice or  passage  of time or both
would  constitute  such a  default  or an  event of  default  on the part of the
Contributor or any such  Affiliate,  as lessee,  has occurred  (which default or
event of default has not been cured). No material default or event of default on
the part of the lessor under the  provisions of any of such  Leaseholds,  and no
event that with the giving of notice or passage of time or both would constitute
such  default or event of default on the part of any such  lessor,  has occurred
(which default or event of default has not been cured).

         (c) The  Contributor  or an Affiliate  thereof has good title to all of
the  personal  property  purported  to be  owned by it,  free  and  clear of all
Encumbrances,  except  for  liens for  Taxes  not yet due and  payable  and such
Encumbrances,  if any, that do not in the aggregate  materially detract from the
value or materially  interfere with the use of the Assets (as they are currently
being used) or as otherwise  would not reasonably be expected to have a Material
Adverse Effect.

         3.6  Title Matters:  Defects in Improvements.  There are no trespassers
or other adverse  parties in possession on or affecting the Fee Interests or the
Leased  Premises that would  reasonably  be expected to have a Material  Adverse
Effect.  Neither the Contributor nor any Affiliate  thereof has granted and none
of the foregoing is party to any unrecorded  options,  rights of refusal,  sales
contracts  or other  such  contractual  rights  in favor  of any  third  parties
relating to the Fee Interests or the Leased Premises. No written notice has been
received by the Contributor or any Affiliate  thereof from any insurance company
with respect to the Fee Interests or the Leased Premises or by any board of fire
underwriters  claiming any material  defects or  deficiencies  or requiring  the
performance  of any repairs,  replacement,  alteration or other work relating to
the improvements situated thereon (in each case, which have not been cured).

         3.7  Working Capital.  The  Contributor  has  operated  the Contributed
Business in the ordinary  course of business  from March 31, 1997 to the Closing
Date such that the Inventory,  Stores  Inventory,  Prepaid Expenses and Accounts
Receivable, as of the Closing Date, are at substantially the same level as would
have existed for the Contributor without regard to the transactions contemplated
by the Master Transaction Agreement.

         3.8   Technology  and  Similar  Rights.  The  Contributor  owns  or  is
licensed  to use  all of the  Intellectual  Property,  Licensed  Technology  and
Licensed  Trademarks,  and the Intellectual  Property,  Licensed  Technology and
Licensed  Trademarks  together  constitute all relevant patents,  pending patent
applications,   invention  disclosures,  copyrights,  software,  trade  secrets,
technical information,  technology, know-how, processes, tradenames, trademarks,
trademark registrations or applications,  copyrights,  copyright applications or
registrations or any derivative  thereof or design used in connection  therewith
necessary for the normal operation and conduct of the Contributed Business as it
is  currently  operated  and  conducted,  except  where the failure to have such
ownership  or  licenses  would not  reasonably  be  expected  to have a Material
Adverse Effect.

         3.9  Government Licenses, Permits and Related Approvals. The Government
Licenses  constitute all those necessary for the normal operation and conduct of
the Contributed Business as it is currently operated and conducted, except where
the failure to have such Government Licenses would not reasonably be expected to
have a Material Adverse Effect.

         3.10  All  Necessary  Assets.   The Assets  together  with  the  rights
under the Related Agreements  constitute all property and other rights necessary
to enable the  Partnership  to operate and conduct the  Contributed  Business in
substantially  the same manner as it is being operated and conducted on the date
of this  Agreement,  except in all cases where the failure of the Partnership to
acquire such  property or other rights by conveyance or license would not in the
aggregate reasonably be expected to have a Material Adverse Effect.

         3.11  Conduct of Business in Compliance with Regulatory and Contractual
Requirements.  The  Contributor,  and any  Affiliate  thereof,  is operating and
conducting the  Contributed  Business in compliance  with all  applicable  Legal
Requirements,  rights of  concession,  licenses,  know-how or other  proprietary
rights of others,  the failure to comply with which would reasonably be expected
to have a Material Adverse Effect.

         3.12  Legal Proceedings. There  is no  litigation,  proceeding,  claim,
grievance,  arbitration,  investigation or other action to which the Contributor
or any Affiliate  thereof is a party (i) that is pending or, to the Knowledge of
the Contributor,  threatened, (ii) that relates in any way to the Assets, to the
operation  or  conduct  of the  Contributed  Business,  or to  the  transactions
contemplated  by this  Agreement,  and (iii)  that upon  resolution  adverse  to
Contributor  or any of its  Affiliates,  could  reasonably be expected to have a
Material Adverse Effect.

of the  Master  Transaction  Agreement,  there are no  Consents  required  to be
obtained by the  Contributor  or any of its  Affiliates in  connection  with the

not yet due and payable) upon the Assets.

         (b) None of the Assets directly or indirectly  secures any indebtedness

reasonable inquiry as to the accuracy and completeness of such  representations,
warranties and Schedules.


                                    SECTION 4
                REPRESENTATIONS AND WARRANTIES OF THE PARTNERSHIP
                -------------------------------------------------

         The Partnership represents and warrants to the Contributor as follows:

         4.1  Due Organization; Good Standing and Power.  The  Partnership  is a
limited partnership duly formed and validly existing under the laws of the State
of Delaware.  The Partnership  has all partnership  power and authority to enter
into  this  Agreement  and the  other  Related  Agreements  and to  perform  its
obligations  hereunder  and  thereunder.  The  Partnership  is duly  authorized,
qualified  or licensed to do business as a foreign  partnership,  in each of the
jurisdictions  in which its right,  title or interest in or to any asset, or the
conduct  of  its  business,   requires  such  authorization,   qualification  or
licensing,  except  where the  failure to so  qualify  would not have a material
adverse  effect on the ability of the  Partnership  to perform  its  obligations
hereunder or under the Assignment and Assumption Agreements.

         4.2  Authorization and Validity of Agreement.  The  execution, delivery
and  performance  of this  Agreement  and the other  Related  Agreements  by the
Partnership  and  the  consummation  by  the  Partnership  of  the  transactions
contemplated  hereby and  thereby  have been duly  authorized  by all  necessary
partnership  action on the part of the Partnership.  No other partnership action
is necessary for the authorization,  execution,  delivery and performance by the
Partnership of this Agreement, the other Related Agreements and the consummation
by the  Partnership of the  transactions  contemplated  hereby or thereby.  This
Agreement and the other Related Agreements have been duly executed and delivered
by the Partnership and constitute  legal,  valid and binding  obligations of the
Partnership,  enforceable in accordance with their terms, except as the same may
be limited by bankruptcy, insolvency, reorganization,  moratorium and other laws
relating to or  affecting  creditors'  rights  generally  and by general  equity
principles.

         4.3  No Consents Required;  No Conflict  with Instruments  to which the
Partnership  is a  Party.  The  execution,  delivery  and  performance  of  this
Agreement  and  the  other  Related   Agreements  by  the  Partnership  and  the
consummation by it of the transactions contemplated thereby (i) will not require
any  Consent  except for such  Consents  the  failure of which to be obtained or
made,  would not in the  aggregate  reasonably  be  expected  to have a Material
Adverse Effect on the Partnership's ability to perform its obligations hereunder
or  thereunder,  and (ii) will not violate (with or without the giving of notice
or the  lapse of time or  both),  conflict  with,  or  result  in the  breach or
termination of any provision of, or constitute a default under, or result in the
acceleration of the performance of the obligations of the Partnership under, the
partnership agreement of the Partnership,  or any indenture,  mortgage,  deed of
trust, lease,  licensing agreement,  contract,  instrument or other agreement to
which  the  Partnership  is a party or by which  the  Partnership  or any of its
assets or properties is bound, except for such violations,  conflicts, breaches,
terminations,  defaults, accelerations or liens which would not in the aggregate
reasonably be expected to have a material  adverse  effect on the  Partnership's
ability to perform its obligations hereunder or thereunder.


                                    SECTION 5
                      COVENANTS SUBSEQUENT TO CLOSING DATE
                      ------------------------------------

         5.1  Access to Information. Following the Closing Date, the Partnership
shall afford,  and will cause its Affiliates to afford, to the Contributor,  its
counsel,  accountants  and  other  authorized  representatives,   during  normal
business hours,  reasonable  access to the books,  records and other data of the
Contributed  Business  with respect to the period prior to the Closing Date (and
any  personnel  familiar  therewith)  to the  extent  that  such  access  may be
reasonably  required by the Contributor to facilitate (i) the preparation by the
Contributor  of such tax returns as it may be  required to file with  respect to
the operations of the Assets and the Contributed  Business or in connection with
any audit,  amended  return,  claim for refund or any  proceeding  with  respect
thereto, (ii) the investigation,  litigation and final disposition of any claims
which may have been or may be made against the  Contributor  in connection  with
the  Assets and the  Contributed  Business,  (iii) the  payment of any amount in
connection  with any  liabilities or obligations  which have not been assumed by
the Partnership under this Agreement and (iv) for any other reasonable  business
purpose.  For a  period  of ten  years  after  the date of this  Agreement,  the
Partnership  will not dispose of,  alter or destroy any such books,  records and
other data without giving 90 days' prior notice to the Contributor to permit it,
at its  expense,  to  examine,  duplicate  or  repossess  such  records,  files,
documents and correspondence.

        5.2  Mail  or  Other  Communications.  The  Contributor  authorizes  and
empowers the  Partnership  on and after the Closing Date to receive and open all
mail received by the  Partnership  relating to the  Contributed  Business or the
Assets  and to deal  with the  contents  of such  communications  in any  proper
manner.  The Contributor  shall promptly  deliver to the Partnership any mail or
other  communication  received by it on and after the Closing Date pertaining to
the Contributed Business or the Assets and any cash, checks or other instruments
of payment to which the Partnership is entitled.  The Partnership shall promptly
deliver to the Contributor any mail or other communication  received by it after
the Closing Date pertaining to the Excluded Assets or Excluded Liabilities,  and
any cash, checks or other instruments of payment in respect of such.

        5.3  Use of  Contributor's  Trade Name.  Except as set forth on Schedule
2.2(d),  after the Closing  Date the  Partnership  shall be permitted to use any
items of Inventory or packaging  material,  any sales or promotional  materials,
any forms or documents or any other printed  material that bear any of the names
"Millennium" or "Quantum" or other statutory  names,  trade names or trademarks,
indications  or  descriptions  of which such names or any name  similar  thereto
forms a part until the  earlier to occur of (i) such time as  inventory  of such
materials  existing as of the Closing Date are used, or (ii) two years after the
Closing Date.

         5.4  Closing  Date  Balance  Sheet.  Not later than 60  days after  the
Closing Date, the  Contributor  shall cause Price  Waterhouse LLP to prepare and
deliver to the  Contributor  and the Partnership an audited balance sheet of the
Contributed Business as of the Closing Date (the "Closing Date Balance Sheet").

         5.5  Payment of Retained Accounts Payable.  The Contributor will retain
all  accounts  payable  including   Retained   Accounts  Payable;   however  the
Partnership,  as payment  agent of the  Contributor,  shall pay such  amounts on
behalf of the  Contributor on a timely basis.  As soon as practicable  following
the end of each month after which such Retained Accounts Payable are paid by the
Partnership,  but in any event within  fifteen days after the end of such month,
each Contributor  will reimburse the Partnership for such payments  attributable
to its Contributed Business.

         5.6  Collection of Accounts Receivable.  The Partnership, as collecting
agent for the  Contributor,  shall take all commercially  reasonable  efforts to
collect the Accounts  Receivable.  As soon as  practicable  after such  Accounts
Receivable are collected,  but in any event within fifteen days after the end of
each month, the Partnership shall remit such collections to the Contributor.  If
the Accounts  Receivable as of the Closing Date as set forth in the Closing Date
Balance Sheet (the "Confirmed Accounts  Receivable") are less than $250 million,
then in addition to the foregoing, the Partnership shall pay the Contributor the
difference between $250 million and the Confirmed Accounts  Receivable within 10
days after the receipt of the  Closing  Date  Balance  Sheet.  If the  Confirmed
Accounts  Receivable are more than $250 million,  the Contributor  shall pay the
Partnership  the  difference  between  $250 million and the  Confirmed  Accounts
Receivable.  Collections on Accounts  Receivable  shall be applied on a specific
identification  basis.  The  Partnership  will  report  monthly  in  writing  to
Contributor  on the amounts  collected  during the  preceding  month,  and shall
provide an aging summary of uncollected  accounts and a detailed  description of
each problem  account (45 or more days  overdue).  On  reasonable  notice to the
Partnership,  Contributor  shall  have  the  right to take  over the  collection
process for any problem account.

         5.7  Reimbursement  for  Prepaid  Expenses.  The  Partnership  and  the
Contributor   acknowledge  that  the  Prepaid   Expenses   attributable  to  its
Contributed  Business have been conveyed to the  Partnership  solely in order to
facilitate the timely and efficient transfer of the Contributed  Business to the
Partnership.  Consequently,  the Partnership shall reimburse the Contributor for
the Prepaid  Expenses  associated with its Contributed  Business (other than the
prepaid expenses for "turnaround" costs) within 10 days following the receipt of
the Closing Date Balance Sheet.


                                    SECTION 6
                          SURVIVAL AND INDEMNIFICATION
                          ----------------------------

         6.1  Survival Limitations.   The representations  and warranties of the
parties  hereto  contained  in this  Agreement  or in any  certificate  or other
writing  delivered  pursuant hereto or in connection  herewith shall survive the
Closing  until the date that is 60 months  after the  Closing  Date,  except (i)
Section 3.14, which shall survive until the expiration of the applicable statute
of limitations and (ii) Section 3.5, which shall survive without  limitation and
shall not be merged with the Deeds. No action can be brought with respect to any
breach of any  representation  or warranty  (except with respect to Section 3.5)
pursuant to this  Agreement  unless a written  notice that complies with Section
6.3 has been  delivered  pursuant to such Section 6.3 prior to the expiration of
the survival period applicable to such representation or warranty; provided that
upon the giving of such  notice,  notwithstanding  any other  provision  of this
Agreement the representation and warranty that is the basis of such action shall
continue with respect to such action beyond the time at which the representation
and warranty would otherwise terminate.

         6.2   Indemnification.

         (a) Subject to the other  provisions of this Section 6, the Contributor
hereby agrees,  to the fullest extent permitted by applicable law, to indemnify,
defend and hold harmless the Partnership and its Affiliates and their respective
officers,  directors and employees  from,  against and in respect of any losses,
claims, damages, fines, penalties,  assessments by public agencies,  settlement,
cost or  expenses  (including  costs of defense and  attorneys'  fees) and other
liabilities  (any of the foregoing being a "Liability")  incurred or suffered by
the Partnership or any of its Affiliates,  arising out of, in connection with or
relating to:

                   (i) Any misrepresentation in or breach of the representations
         and  warranties  of the  Contributor  or any of its  Affiliates in this
         Agreement,  the  Assignment  and  Assumption  Agreements,   the  Master
         Intellectual Property Agreement, or the Master Transaction Agreement;

                   (ii) Any failure of the  Contributor or any of its Affiliates
         to  perform  any of its  covenants  or  obligations  contained  in this
         Agreement,  the  Assignment  and  Assumption  Agreements,   the  Master
         Intellectual Property Agreement, or the Master Transaction Agreement;

                   (iii)   Excluded Liabilities; or

                   (iv)    Any Pre-Closing  Contingent Liability that is  not an
         Assumed Liability;

                    provided,  however,  that the  following  limitations  shall
         apply to the Contributor's  indemnification  obligations in clauses (i)
         and (iv) above:

                   (A)  the  Contributor  shall  not  have  any  indemnification
         obligation under clause (i) and (iv) above for any individual Liability
         unless the amount of such Liability  exceeds  $25,000 (the  "Individual
         Basket") (it being  understood  that all  Liabilities  arising from the
         same event, condition or set of circumstances shall be considered as an
         individual  Liability  for  purposes of such  calculation),  but if the
         amount of such  Liability  exceeds the  Individual  Basket,  the entire
         amount  of  such  Liability,   including  the  first  $25,000  of  such
         Liability, may be the subject of indemnification  hereunder;  provided,
         further,  that the parties agree that the amount of Liability for which
         indemnification  may be  sought  for  breach of any  representation  or
         warranty under clause (i) above shall be calculated taking into account
         the  Individual  Basket  but  without  regard to any  qualification  or
         exception   regarding    materiality   or   Material   Adverse   Effect
         qualification  contained in such  representation  or warranty (it being
         understood   that  such   materiality   or  Material   Adverse   Effect
         qualifications  shall apply for purposes of  determining  whether there
         has  been  such a  breach  in the  first  place,  but  once it has been
         established  that  there is such a  breach,  the  Partnership  shall be
         entitled to indemnity relating back to the first dollar); and

                   (B) to the extent any  misrepresentation  in or breach of the
         representations   and  warranties  of  the  Contributor  results  in  a
         Liability of the  Partnership  in excess of the  Individual  Basket and
         such  Liability   would  also   constitute  a  Pre-Closing   Contingent
         Liability,  such  misrepresentation  or breach  shall be  treated  as a
         Pre-Closing Contingent Liability.

         (b)  NOTWITHSTANDING  ANY OTHER  PROVISION  OF THIS  AGREEMENT,  TO THE
FULLEST EXTENT  PERMITTED BY LAW, NEITHER THE CONTRIBUTOR NOR ANY OF ITS AGENTS,
EMPLOYEES,  REPRESENTATIVES  OR  AFFILIATES  SHALL BE LIABLE FOR  CONSEQUENTIAL,
INCIDENTAL, INDIRECT OR PUNITIVE DAMAGES IN CONNECTION WITH DIRECT CLAIMS BY THE
PARTNERSHIP  (I.E., A CLAIM BY THE PARTNERSHIP THAT DOES NOT SEEK  REIMBURSEMENT
FOR A THIRD  PARTY  CLAIM PAID OR PAYABLE BY THE  PARTNERSHIP)  WITH  RESPECT TO
THEIR  INDEMNIFICATION  OBLIGATIONS  UNDER THIS AGREEMENT  UNLESS ANY SUCH CLAIM
ARISES OUT OF THE FRAUDULENT  ACTIONS OF THE  CONTRIBUTOR.  IN  DETERMINING  THE
AMOUNT OF ANY LOSS, LIABILITY,  OR EXPENSE FOR WHICH THE PARTNERSHIP IS ENTITLED
TO  INDEMNIFICATION  UNDER THIS  AGREEMENT,  THE GROSS  AMOUNT  THEREOF  WILL BE
REDUCED  (BUT NOT  BELOW  ZERO)  BY THE NET  PRESENT  VALUE  OF ANY  CORRELATIVE
INSURANCE  PROCEEDS  ACTUALLY  REALIZED BY THE PARTNERSHIP UNDER POLICIES TO THE
EXTENT THAT THE FUTURE PREMIUM RATE WILL NOT BE INCREASED BY CLAIM EXPERIENCE.

         (c)   Notwithstanding   the   provisions  of  Sections   6.2(a)(i)  and
6.2(a)(iv), it is expressly agreed that the Contributor shall not be required to
indemnify the Partnership  for any Liability  arising out of, in connection with
or  related  to  any  HSE  Claim  to  the  extent  that  the  condition,  event,
circumstance  or other basis for the HSE Claim was exacerbated or accelerated by
the  Partnership.  The  Partnership  shall not be deemed to have  exacerbated  a
condition,  event, circumstance or other basis for an HSE Claim by reason of the
continuance  thereof  after  the  Closing  (i)  under  circumstances  where  the
Partnership  does not know of its  existence and has not breached any legal duty
to have  conducted an  investigation  or inquiry that would have  uncovered  the
matter  or (ii)  under  circumstances  where  the  Partnership  does know of its
existence but is taking commercially reasonable actions to cure the matter or to
otherwise achieve compliance in a commercially reasonable and prudent manner.

         (d) Subject to the other  provisions of this Section 6, the Partnership
hereby indemnifies,  to the fullest extent permitted by law, the Contributor and
its Affiliates against and agrees to hold each of them harmless from any and all
Liability  incurred  or  suffered by the  Contributor  or any of its  Affiliates
arising out of or relating to:

                   (i) Any misrepresentation in or breach of the representations
         and warranties of the  Partnership or the failure of the Partnership to
         perform any of its covenants or obligations contained in this Agreement
         and the Assignment and Assumption Agreements or the Master Intellectual
         Property Agreement;

                   (ii)    Assumed Liabilities; or

                   (iii)  Any  HSE  Claim  to  the  extent  arising  out  of the
         Partnership's exacerbation or acceleration of such HSE Claim.

         (e)  NOTWITHSTANDING  ANY OTHER  PROVISION  OF THIS  AGREEMENT,  TO THE
FULLEST EXTENT  PERMITTED BY LAW, NEITHER THE PARTNERSHIP NOR ANY OF ITS AGENTS,
EMPLOYEES,  REPRESENTATIVES  OR  AFFILIATES  SHALL BE LIABLE FOR  CONSEQUENTIAL,
INCIDENTAL, INDIRECT OR PUNITIVE DAMAGES IN CONNECTION WITH DIRECT CLAIMS BY THE
CONTRIBUTOR  WITH  RESPECT  TO  THEIR  INDEMNIFICATION  OBLIGATIONS  UNDER  THIS
AGREEMENT  UNLESS ANY SUCH CLAIM  ARISES  OUT OF THE  FRAUDULENT  ACTIONS OF THE
PARTNERSHIP.  IN DETERMINING THE AMOUNT OF ANY LOSS,  LIABILITY,  OR EXPENSE FOR
WHICH THE CONTRIBUTOR IS ENTITLED TO INDEMNIFICATION  UNDER THIS AGREEMENT,  THE
GROSS  AMOUNT  THEREOF  WILL BE REDUCED  (BUT NOT BELOW ZERO) BY THE NET PRESENT
VALUE OF ANY CORRELATIVE INSURANCE PROCEEDS ACTUALLY REALIZED BY THE CONTRIBUTOR
UNDER  POLICIES TO THE EXTENT THE FUTURE  PREMIUM  RATE WILL NOT BE INCREASED BY
CLAIM EXPERIENCE.

         (f) The rights provided to the Partnership  pursuant to this Section 6,
as limited  by and  subject to the  provisions  of this  Section 6, shall be the
Partnership's  sole  remedy  for breach of  representation  and  warranty  by or
covenant or obligation of the Contributor  under this Agreement,  the Assignment
and Assumption  Agreements and the Master Intellectual  Property Agreement.  The
rights provided to the Contributor pursuant to this Section 6, as limited by and
subject to the  provisions  of this Section 6, shall be the  Contributor's  sole
remedy for breach of representation and warranty by or covenant of obligation of
the Partnership under this Agreement,  the Assignment and Assumption  Agreements
and the Master Intellectual Property Agreement.

         6.3   Procedures.

         (a)  Any  Person  seeking   indemnification   under  Section  6.2  (the
"Indemnified  Party")  agrees to give prompt written notice to the party against
whom  indemnity  is sought (the  "Indemnifying  Party") of the  assertion of any
claim that does not involve a Third Party Claim,  which notice shall describe in
reasonable  detail the nature of the claim, an estimate of the amount of damages
attributable  to  such  claim  to the  extent  feasible  and  the  basis  of the
Indemnified  Party's request for  indemnification  under this Agreement.  If the
Indemnifying  Party  disputes such claim and such dispute is not resolved by the
parties, such dispute shall be resolved in accordance with Section 7.9.

         (b) If an  Indemnified  Party is  notified of a Third Party Claim which
may give rise to a claim for  indemnification  against  any  Indemnifying  Party
under this  Section,  then the  Indemnified  Party  shall  promptly  notify each
Indemnifying  Party  thereof in writing  (including  copies of all papers served
with  respect to such  Third  Party  Claim),  which  notice  shall  describe  in
reasonable detail the nature of the Third Party Claim, an estimate of the amount
of damages  attributable to the Third Party Claim to the extent feasible and the
basis  of  the  Indemnified  Party's  request  for  indemnification  under  this
Agreement;  provided  that any  failure  to timely  give such  notice  shall not
relieve the  Indemnifying  Party of any of its obligations  under this Section 6
except to the extent that such failure  prejudices  or impairs,  in any material
respect, any of the rights or obligations of the Indemnifying Party.

         (c) Any  Indemnifying  Party may, and at the request of the Indemnified
Party  shall,  participate  in and  control the defense of the Third Party Claim
with counsel of its choice reasonably satisfactory to the Indemnified Party. The
Indemnified  Party shall have the right to employ  separate  counsel in any such
action and to participate in the defense  thereof,  but the fees and expenses of
such  counsel  shall be at the expense of the  Indemnified  Party unless (i) the
employment   thereof  has  been  specifically   authorized  in  writing  by  the
Indemnifying Party, (ii) the Indemnifying Party failed to assume the defense and
employ counsel or failed to diligently prosecute or settle the Third Party Claim
or (iii) there shall exist or develop a conflict that would  ethically  prohibit
counsel to the Indemnifying  Party from  representing the Indemnified  Party. If
requested by the Indemnifying  Party, the Indemnified  Party agrees to cooperate
with the Indemnifying  Party and its counsel in contesting any Third Party Claim
that the Indemnifying Party elects to contest, including, without limitation, by
making any  counterclaim  against the person or entity asserting the Third Party
Claim or any cross-complaint  against any person or entity, in each case only if
and to the extent that any such counterclaim or cross-complaint  arises from the
same  actions or facts giving rise to the Third Party  Claim.  The  Indemnifying
Party  shall  be the  sole  judge  of the  acceptability  of any  compromise  or
settlement of any claim,  litigation or proceeding in respect of which indemnity
may be sought  hereunder,  provided  that the  Indemnifying  Party will give the
Indemnified   Party  reasonable  prior  written  notice  of  any  such  proposed
settlement  or  compromise  and will not consent to the entry of any judgment or
enter into any  settlement  with  respect to any Third Party  Claim  without the
prior written consent of the Indemnified  Party, which shall not be unreasonably
withheld.  The  Indemnifying  Party (if the  Indemnified  Party is  entitled  to
indemnification  hereunder)  shall  reimburse  the  Indemnified  Party  for  its
reasonable out of pocket costs incurred with respect to such cooperation.

         (d) If the  Indemnifying  Party  fails to assume the defense of a Third
Party Claim within a reasonable  period after receipt of written notice pursuant
to the first sentence of subparagraph (c), or if the Indemnifying  Party assumes
the defense of the  Indemnified  Party  pursuant to  subparagraph  (c) but fails
diligently  to prosecute or settle the Third Party Claim,  then the  Indemnified
Party  shall  have the  right to  defend,  at the sole cost and  expense  of the
Indemnifying  Party (if the  Indemnified  Party is entitled  to  indemnification
hereunder),  the  Third  Party  Claim  by  all  appropriate  proceedings,  which
proceedings shall be promptly and vigorously prosecuted by the Indemnified Party
to a final conclusion or settled.  The Indemnified Party shall have full control
of such defense and proceedings;  provided that the Indemnified  Party shall not
settle such Third Party Claim  without the written  consent of the  Indemnifying
Party, which consent shall not be unreasonably  withheld. The Indemnifying Party
may participate in, but not control, any defense or settlement controlled by the
Indemnified  Party pursuant to this Section,  and the  Indemnifying  Party shall
bear its own costs and expenses with respect to such participation.

         (e)  Notwithstanding  the other  provisions of this Section 6.3, if the
Indemnifying  Party disputes its potential  liability to the  Indemnified  Party
under  this  Section  6.3  and if such  dispute  is  resolved  in  favor  of the
Indemnifying  Party,  the  Indemnifying  Party shall not be required to bear the
costs and expenses of the Indemnified  Party's defense  pursuant to this Section
6.3 or of the  Indemnifying  Party's  participation  therein at the  Indemnified
Party's  request,  and the Indemnified  Party shall  reimburse the  Indemnifying
Party in full for all costs  and  expenses  of the  litigation  concerning  such
dispute.  If a dispute  over  potential  liability  is  resolved in favor of the
Indemnified  Party, the Indemnifying Party shall reimburse the Indemnified Party
in full for all costs of the litigation concerning such dispute.

         (f) After it has been  determined,  by  acknowledgment,  agreement,  or
ruling of court of law, that an Indemnifying  Party is liable to the Indemnified
Party under this Section 6, the Indemnifying Party shall pay or cause to be paid
to the Indemnified Party the amount of the Liability within ten business days of
receipt by the Indemnifying Party of a notice reasonably itemizing the amount of
the  Liability  but  only  to  the  extent  actually  paid  or  suffered  by the
Indemnified Party.

         (g) In the event a Third Party Claim is brought in which the  liability
as between the  Partnership and the Contributor is alleged to be joint (it being
agreed that any Third Party Claim related to a Pre-Closing  Contingent Liability
shall be deemed joint) or in which the entitlement to indemnification under this
Section 6 has not been  determined,  the Partnership  and the Contributor  shall
cooperate in the joint defense of such Third Party Claim and shall offer to each
other such  assistance  as may  reasonably  be  requested in order to ensure the
proper and adequate  defense of any such  matter.  Such joint  defense  shall be
under the general  management and  supervision of the party which is expected to
bear the greater share of the  liability,  unless  otherwise  agreed;  provided,
however,  that neither party shall settle or  compromise  any such joint defense
matter without the consent of the other, which consent shall not be unreasonably
withheld or delayed. Any uninsured costs of such joint defense shall be borne as
the parties may agree, provided, however, that in the absence of such agreement,
the defense costs shall be borne by the party  incurring  such costs;  provided,
further,   that,   if  it  is   determined   that  one  party  was  entitled  to
indemnification  under this Section 6, the other party shall reimburse the party
entitled to  indemnification  for all of its costs  incurred in connection  with
such defense.

         6.4  Subrogation. In  the event  of  any  payment  by  an  Indemnifying
Party to an Indemnified Party in connection with any Liability, the Indemnifying
Party shall be  subrogated  to and shall  stand in the place of the  Indemnified
Party as to any events or  circumstances  in  respect  of which the  Indemnified
Party may have any right or claim against any third party relating to such event
or indemnification.  The Indemnified Party shall cooperate with the Indemnifying
Party in any reasonable manner in prosecuting any subrogated claim.

         6.5  Claims for HSE Work.  Notwithstanding the other provisions of this
Section  6,  in the  case  of any  assertion,  claim  or  demand  requiring  the
performance  of  investigatory,   removal  or  remedial  work  with  respect  to
(environmental  conditions,  HSE  Laws or  Chemical  Substances  for  which  the
Partnership may seek  indemnification,  the Partnership  shall have the right to
conduct and control such work provided (i) it uses its good faith,  commercially
reasonable  efforts to achieve the Lowest Cost Response and (ii) it provides the
Contributor  with the opportunity to: (A) review and comment upon any work plans
for any remedial action prior to  finalization  and  implementation;  (B) attend
meetings  with  regulators  concerning  the  remedial  action;  and  (C)  have a
representative present during the performance of any remedial action.

         6.6  EXTENT OF  INDEMNIFICATION.  WITHOUT  LIMITING  OR  ENLARGING  THE
SCOPE OF THE  INDEMNIFICATION,  RELEASE  AND  ASSUMPTION  OBLIGATIONS  SET FORTH
HEREIN,  TO THE FULLEST EXTENT  PERMITTED BY LAW, AN INDEMNIFIED  PARTY SHALL BE
ENTITLED TO  INDEMNIFICATION  HEREUNDER  IN  ACCORDANCE  WITH THE TERMS  HEREOF,
REGARDLESS  OF  WHETHER  THE   INDEMNIFIABLE   LOSS  GIVING  RISE  TO  ANY  SUCH
INDEMNIFICATION  OBLIGATION IS THE RESULT OF THE SOLE, GROSS,  ACTIVE,  PASSIVE,
CONCURRENT  OR  COMPARATIVE  NEGLIGENCE,  STRICT  LIABILITY  OR  OTHER  FAULT OR
VIOLATION OF ANY LAW OF OR BY ANY SUCH INDEMNIFIED PARTY. THE PARTIES AGREE THAT
THIS STATEMENT CONSTITUTES A CONSPICUOUS LEGEND.

                               -------------------


                  The Contributor makes no exceptions to the representations and
warranties  made by it in Section 3 of this  Agreement  except for the following
exception to its representations made in Section 3.4 of this Agreement:

                  Millennium Chemicals Inc. ("Millennium") has received a letter
from the Pension Benefit  Guaranty  Corporation (the "PBGC") dated September 10,
1997  expressing a concern that the actions  contemplated by the Agreement would
increase the risk to the PBGC relating to the Millennium  Defined Benefit Plans.
In that letter, the PBGC noted that it could seek to involuntarily terminate the
Plan prior to the Closing Date if it determined that the transaction would cause
the risk to the PBGC to increase unreasonably.  The letter went on to state that
this measure  would be viewed as a last resort and that the PBGC would prefer to
enter into a consensual agreement to protect the Plan.

                  Millennium has provided the PBGC with  information  explaining
the  transaction  pursuant  to a  Confidentiality  Agreement  with the PBGC.  In
addition,  Millennium has spoken with  representatives at the PBGC regarding the
transaction and the PBGC and Millennium have executed an agreement for which, in
consideration of Millennium  agreeing to certain  covenants,  the PBGC agreed to
forbear from instituting proceedings to terminate the Plans.

                                   Appendix A

                          Dispute Resolution Procedures
                          -----------------------------


         (1) Binding and Exclusive Means. The dispute resolution  provisions set
forth in this Appendix A shall be the binding and exclusive means to resolve all
disputes arising under this Agreement (each a "Dispute").

         (2) Standards and Criteria. In resolving any Dispute, the standards and
criteria  for  resolving  such dispute  shall,  unless the  Contributor  and the
Partnership in their discretion jointly stipulate otherwise,  be as set forth in
Appendix 1 to this Appendix A.

         (3) ADR and Binding  Arbitration  Procedures.  If a Dispute arises, the
following procedures shall be implemented:

         (a)  The  Indemnifying  Party  may  at  any  time  invoke  the  dispute
resolution  procedures  set  forth  in  this  Appendix  A as to any  Dispute  by
providing  written notice of such action to the  Indemnified  Party,  who within
five  Business  Days after such  notice  shall  schedule a meeting to be held in
Houston,  Texas between the parties.  The meeting shall occur within 10 Business
Days after  notice of the meeting is delivered to the  Indemnifying  Party.  The
meeting   shall  be   attended   by   representatives   of  each  party   having
decision-making   authority  regarding  the  Dispute  as  well  as  the  dispute
resolution process and who shall attempt in a commercially  reasonable manner to
negotiate a resolution of the Dispute.

         (b)  The   representatives   of  the  parties  shall   cooperate  in  a
commercially  reasonable  manner and shall explore  whether  techniques  such as
mediation,  minitrials,  mock trials or other techniques of alternative  dispute
resolution might be useful. In the event that a technique of alternative dispute
resolution is so agreed upon, a specific  timetable and completion  date for its
implementation  shall also be agreed upon. The representatives  will continue to
meet and discuss settlement until the date (the "Interim Decision Date") that is
the earliest to occur of the following events: (i) an agreement shall be reached
by the parties  resolving the Dispute;  (ii) one of the parties shall  determine
and notify the other party in writing that no agreement resolving the Dispute is
likely to be reached;  (iii) if a technique of alternative dispute resolution is
agreed upon, the completion date therefor shall occur without the parties having
resolved  the  Dispute;  or (iv) if another  technique  of  alternative  dispute
resolution is not agreed upon,  two full meeting days (or such other time period
as may be agreed  upon) shall  expire  without the parties  having  resolved the
Dispute.

         (c) If, as of the Interim Decision Date, the parties have not succeeded
in  negotiating  a resolution  of the dispute  pursuant to  subsection  (b), the
parties shall proceed under subsection (d).
                                                    
         (d) The parties  shall jointly  appoint a Neutral.  If the parties have
been  unable to agree upon such  appointment  within 30 days  after the  Interim
Decision Date, then such Neutral,  upon the application of either of the parties
shall be  appointed  within  10 days of the  filing of such  application  by the
Center for Public Resources, or if such appointment is not so made promptly then
promptly  thereafter by the American  Arbitration  Association in  Philadelphia,
Pennsylvania,  or if such  appointment  is not so made  promptly  then  promptly
thereafter  by  the  senior  United  States  District  Court  judge  sitting  in
Wilmington,  Delaware.  The fees of the  Neutral  shall be paid  equally  by the
parties except that the Neutral shall have discretion to award fees.

         (e) In  consultation  with the Neutral,  the parties shall agree upon a
binding  schedule  and  procedure  (which  procedure  may have  been  previously
discussed  under  subsection (b)) to be used as a means to resolve or to attempt
to resolve  Dispute,  with the Neutral  making the  decision as to the  schedule
and/or procedure if the parties have been unable to agree on any of such matters
within 20 days after the initial selection of the Neutral.  The parties agree to
participate  in a  commercially  reasonable  manner  in  the  procedure  to  its
conclusion as determined  by the Neutral.  If the parties are not  successful in
resolving the Dispute through the procedure  described  above,  then the parties
agree that (i) the Neutral shall act as the arbitrator in a binding  arbitration
in accordance with the American Arbitration Association rules and shall render a
decision  and (ii)  judgment  upon the  decision  rendered by the Neutral may be
entered in any court having jurisdiction.

         (4)  Continuation  of Business.  Notwithstanding  the  existence of any
Dispute or the  pendency  of any  procedures  pursuant  to this  Appendix A, the
parties agree and undertake  that all payments not in dispute shall  continue to
be made and all obligations not in dispute shall continue to be performed.

                                   ----------


         (a) First priority shall be given to maximizing the  consistency of the
resolution of the Dispute with the  satisfaction  of all express  obligations of
the parties and their Affiliates as set forth in the Agreement.

         (b) Second  priority  shall be given to  resolution of the Dispute in a
manner  which best  achieves  the  objectives  of the  business  activities  and
arrangements under the Agreement and permits the parties to realize the benefits
intended to be afforded thereby.

         (c) Third priority shall be given to such other matters, if any, as the
parties  or  the  Neutral   shall   determine  to  be   appropriate   under  the
circumstances.

with  the  benefits  of  such  Government  Licenses,  Contributed  Contracts  or
warranties so made available to the  Partnership.  If the Contributor  obtains a
Consent to assign any Government  Licenses,  Contributed  Contract or warranties
after the  Closing,  each such  Government  Licenses,  Contributed  Contract  or
warranties shall be deemed to be assigned to the Partnership promptly after such
Consent is obtained.

         (d)  Following the Closing, the Contributor,  Contributing  Partner and
the Partnership  shall cooperate in good faith and in a commercially  reasonable
manner with respect to all matters pertinent to the carrying into effect of this
Agreement and the  discharge by each party of its  obligations  and  liabilities
hereunder  and  thereunder,  and shall  furnish to each other such  information,
cooperation and assistance as reasonably may be requested in connection with the
foregoing.

         2.5  Assumption of Liabilities.

         (a)  On the terms and subject to the conditions, including Section 6.2,
set forth in this  Agreement,  on the Closing Date, the debts,  liabilities  and
obligations of the  Contributor and its  Contributed  Subsidiaries  set forth in
this Section 2.5 shall be assumed by the Contributing Partner in connection with
the  transfer  of  Assets  to it and  shall be  assumed  by the  Partnership  in
connection with the transfer of Assets to it, and the Partnership agrees to pay,
perform and discharge all such debts, liabilities and obligations when due:

                   (i) All obligations  arising after the Closing Date under the
         Contracts  and Leases that are  assigned to the  Partnership  hereunder
         unless and to the extent that such obligation arises out of a violation
         of such Contract or Lease prior to the Closing Date;

                   (ii) All  obligations  under purchase  orders accepted by the
         Contributor or its  Contributed  Subsidiaries in the ordinary course of
         business of the Contributed Business prior to the Closing Date that are
         not filled as of the Closing Date;

                   (iii) Current accrued expenses  related to employee  vacation
         and lag-week accruals for employees that become Partnership Employees;

                   (iv) All  obligations  and  liabilities,  of  every  kind and
         nature,  without  limitation,  arising  out of, in  connection  with or
         related to the  ownership,  operation  or use after the Closing Date of
         the Assets or the Contributed Business;

                   (v)  Seven  Year  PCCL  Claims to the  extent  the  aggregate
         thereof does not exceed  $7,000,000;  

                   (vi) Third Party Claims that are related to Pre-Closing 
         Contingent  Liabilities and that are first asserted seven years or more
         after the Closing Date;

                   (vii)   The obligations for indebtedness described on
         Schedule 2.5(a)(vii);

                   (viii)  [Reserved];

                   (ix) All Liabilities  associated with products sold after the
         Closing Date regardless of when manufactured;

                   (x)     The long-term liabilities set forth on Schedule 
         2.5(a)(x); and

                   (xi)  Any  other  Liability   specifically   assumed  by  the
         Partnership pursuant to the terms of this Agreement.

The  liabilities and  obligations  assumed by the  Partnership  pursuant to this
Section are  sometimes  hereinafter  referred to  collectively  as the  "Assumed
Liabilities."

         (b)  On  the  Closing  Date,  the  Partnership  shall  deliver  to  the
Contributor an instrument of assumption of the Assumed Liabilities substantially
in the form attached hereto as Exhibit F (the "Assumption Agreement").

         2.6  Excluded  Liabilities.   Except as otherwise expressly provided in
this  Agreement  (including,  without  limitation,  Sections 6.2 and 7.2) or the
Assumption  Agreement,  the Partnership is assuming only the Assumed Liabilities
and is not assuming any other  liability or obligation of the Contributor or any
Affiliate thereof, of whatever nature, whether presently in existence or arising
hereafter,  whether known or unknown, or whether absolute or contingent, and all
such other  liabilities  and  obligations of the  Contributor  and any Affiliate
thereof  that are not  Assumed  Liabilities  shall  be  retained  by and  remain
obligations  and  liabilities  of the  Contributor  or such  Affiliate (all such
liabilities  and   obligations   being  herein  referred  to  as  the  "Excluded
Liabilities"), including the following:

                   (i)  Any Pre-Closing Contingent Liability that is not an 
         Assumed Liability;

                   (ii) any  obligation or liability  relating  to  the Excluded
         Assets; and

                   (iii)  any  obligation  (A)  for  the  payment  of  severance
         benefits  to  employees  of the  Contributor  or any of its  Affiliates
         except as set forth in Sections  2.8(b) or (c), or (B)  attributable to
         Contributor's  or any of its  Affiliates'  employment  of any employee,
         agent or independent contractor prior to the Closing Date.

         2.7   Master Intellectual Property Agreement.

         On the Closing Date, the Partnership and Contributor  shall execute and
deliver a master  intellectual  property  agreement  (the  "Master  Intellectual
Property  Agreement")  in  substantially  the form attached  hereto as Exhibit G
providing, among other things, the following:

         (a)  Non-exclusive,  royalty-free  licenses to the  Partnership  of any
Intellectual Property and Trademarks used, contemplated for use or that could be
used,  in the  Contributed  Business  that is not  conveyed  to the  Partnership
pursuant to Section 2.1.

         (b)  Non-exclusive,  royalty-free  licenses to the  Contributor  or its
Affiliates of any Contributed  Intellectual Property acquired by the Partnership
pursuant to Section 2.1 of this  Agreement  used,  contemplated  for use or that
could be used in the business of the Contributor or its Affiliates.

         (c) The  assignment  of the  Contributed  Intellectual  Property to the
Partnership.

         2.8   Employee Matters.  If the Closing Date occurs prior to January 1,
1998, the effective employment date shall be January 1, 1998 and the Contributor
and the Partnership  shall enter into an agreement to provide employee  services
to the Partnership through December 31, 1997.

         (a) At or prior to the Closing,  the Partnership  shall determine which
employees of the Contributor or any Affiliate thereof will be offered employment
by the Partnership. Any such employee that accepts such offer is herein called a
"Partnership Employee." Partnership Employees shall be employed effective on (i)
January 1,  1998,  or (ii) if the  Closing  Date is after  January 1, 1998,  the
Closing Date.

         (b) If, within six months after the Closing Date or in  anticipation of
Closing,  the Contributor or any Affiliate  thereof  terminates  (other than for
cause) the  employment  of any  employee  of the  Contributor  or any  Affiliate
thereof who is primarily  associated with the Assets or the Contributed Business
but who does not become a Partnership Employee, then the Partnership will pay to
the  Contributor  an  amount  equal to the Basic  Severance  to the  extent  the
Contributor or any Affiliate  thereof pays the Basic Severance to such employee.
"Basic  Severance"  means two weeks of base pay for each full year of service by
the employee with the  Contributor or any Affiliate (or  predecessors of either,
to the extent service therefor is credited by the Contributor),  subject to a 52
week maximum and a 12 week minimum; provided,  however, that with respect to any
employee who has an employment  agreement that contains provisions providing for
one or more  payments  in the event of a change in control  of the  Contributor,
"Basic  Severance"  means  up  to 52  weeks  of  base  pay  notwithstanding  the
employee's years of service.

         (c) Any  Partnership  Employee  whose  employment  is terminated by the
Partnership  (other than for cause)  within six months  after the  Closing  Date
shall be entitled to receive a severance  benefit from the Partnership  equal to
the Basic  Severance  (which,  for purposes of calculating  service time,  shall
include the employee's time of service with the  Contributor,  its  predecessors
(to  the  extent  service  therefor  is  credited  by the  Contributor)  and the
Partnership).

         (d) Any  employees  of the  Contributor  that the  Partnership  and the
Contributor  agree are  necessary  for the orderly  transfer of the  Contributed
Business  to the  Partnership  but who will  not  become  Partnership  Employees
("Transition  Employees")  shall be compensated by the  Contributor on terms and
conditions  and for a  duration  to be agreed  upon by the  Partnership  and the
Contributor. The Partnership shall reimburse the Contributor for any such agreed
upon   compensation,   including  payroll  taxes,   benefit  costs  and  workers
compensation  premiums and claims, paid by the Contributor to or with respect to
any Transition Employee.

         (e) If any employee of the  Contributor  is eligible for and  receiving
short  term  disability  benefits  or sick  pay as of the  Closing  Date and the
Partnership  has offered  such  employee  employment  by the  Partnership,  that
employee  shall become  employed by the  Partnership  (and become a  Partnership
Employee for purposes of this Section 2.8) upon  eligibility to return to active
employment  with  the  Contributor  under  the  applicable   conditions  of  the
Contributor's  short  term  disability  benefits  or sick pay plan.  Partnership
employment  shall not be  effective  until  the  Contributor  verifies  that the
employee has satisfied the conditions  (if any) to return to active  employment.
Until such time as such employee becomes a Partnership  Employee the Contributor
shall continue to bear all costs and expenses associated with such employee.

         (f) Neither the  Contributor  nor any of its Affiliates  shall,  at any
time prior to 60 days after the Closing Date,  effect a "plant closing" or "mass
layoff",  as those terms are  defined in the Worker  Adjustment  and  Retraining
Notification  Act of 1988 ("WARN"),  affecting in whole or in part any facility,
site of employment,  operating unit or employee of the Contributor or any of its
Affiliates  without  complying  fully with the  notice and all other  applicable
requirements of WARN.

         (g) In connection  with the  development by the  Partnership of benefit
plans  and  programs  for  Partnership  Employees  as  provided  in  the  Master
Transaction Agreement,  (i) the Contributor may direct the trustee of any of its
employee  plans to  transfer  assets and  liabilities  in those  employee  plans
associated  with the accrued  benefits of Partnership  Employees to a comparable
Partnership  benefit plan in which the Partnership  Employees  participate,  and
(ii) the  Contributor  or any of its  Affiliates  may direct the  trustee of its
grantor trust to transfer  assets and  liabilities  relating to any accounts for
Partnership Employees under an executive deferral plan to a trust established by
the Partnership to provide  benefits under a comparable  non-qualified  deferred
compensation plan;  provided,  however,  with respect to (i) and (ii) above, the
assets associated with any such plans, as of the Closing Date, are not less than
the  liabilities  associated  therewith as determined by the  Partnership  and a
trust to trust  transfer  of  assets  does not  result in a  taxable  event.  In
connection with the development and  implementation  of such plans and programs,
the  Partnership  agrees,  for purposes of calculating  service time, to include
each employee's time of service with the  Contributor,  its predecessors (to the
extent service therefor is credited by the Contributor) or the Partnership.

         (h) To the extent that the Partnership adopts benefit plans or policies
that contemplate the provision of  post-retirement  life and medical benefits to
the  Partnership  Employees,  the  Partnership  shall record and  recognize,  in
accordance with GAAP, the associated liability for providing the post-retirement
life and medical benefits to the Partnership Employees.

         2.9       Joint Contracts.

         (a) Any Contributed  Contracts  contributed to the Partnership pursuant
to Section 2.1 that relate  principally  to the  Contributed  Business  but also
relate to the business (other than the Contributed  Business) of the Contributor
or its Affiliates  will be made available to the  Contributor and its Affiliates
by the  Partnership  pursuant  to  the  Shared  Services  Agreements  and  other
arrangements by which the Contributor and its Affiliates will enjoy the benefits
of such  Contributed  Contracts as they relate to their business (other than the
Contributed Business) on the same terms and conditions as the Partnership.

         (b) Any Contracts that relate  principally to the business  (other than
the  Contributed  Business) of the Contributor or its Affiliates but also relate
to the  Contributed  Business will be made  available to the  Partnership by the
Contributor or its  Affiliates  pursuant to the Shared  Services  Agreements and
other  arrangements  by which the  Partnership  will enjoy the  benefits of such
Contracts  as they  relate to the  Contributed  Business  on the same  terms and
conditions as the Contributor or its Affiliates.


                                    SECTION 3
                REPRESENTATIONS AND WARRANTIES OF THE CONTRIBUTOR
                -------------------------------------------------

         Except  as  set  forth  on  Schedule  3 or  in  the  SEC  Reports,  the
Contributor represents and warrants to the Partnership as follows:

         3.1  Due Organization;  Good Standing  and Power.  The Contributor is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware and has the corporate power and authority to own, lease
and  operate  the  properties  to be  contributed  hereunder  and to conduct the
Contributed  Business as now conducted by it. The  Contributor has all corporate
power  and  authority  to enter  into  this  Agreement  and the  Assignment  and
Assumption  Agreements and to perform its obligations  hereunder and thereunder.
The  Contributor is duly  authorized,  qualified or licensed to do business as a
foreign corporation,  and is in good standing, in the State of Texas and in each
of the other jurisdictions in which its right, title or interest in or to any of
the  Assets  held by it,  or the  conduct  of the  Contributed  Business  by it,
requires  such  authorization,  qualification  or  licensing,  except  where the
failure to so qualify or to be in good standing would not reasonably be expected
to have a Material Adverse Effect.

         3.2  Authorization and Validity of Agreements.  The execution, delivery
and  performance  of this  Agreement and the other  Related  Agreements by the s
Contributor and the consummation by it of the transactions  contemplated  hereby
and  thereby  have  been  duly  authorized  by the  Board  of  Directors  of the
Contributor.  Except to the extent  heretofore  obtained,  no other corporate or
stockholder action is necessary for the authorization,  execution,  delivery and
performance  by  the  Contributor  of  this  Agreement  and  the  other  Related
Agreements  and  the   consummation  by  the  Contributor  of  the  transactions
contemplated hereby or thereby.  This Agreement and the other Related Agreements
have been duly executed and delivered by the Contributor  and constitute  legal,
valid and binding obligations of the Contributor, enforceable in accordance with
their  terms,  except  as the same may be  limited  by  bankruptcy,  insolvency,
reorganization,  moratorium  and other laws relating to or affecting  creditors'
rights generally and by general equity principles.

         3.3 No Consents  Required;  No Conflict with  Instruments  to which the
Contributor  is a  Party.  The  execution,  delivery  and  performance  of  this
Agreement  and  the  other  Related  Agreements  by  the  Contributor  or by any
Affiliate of the Contributor that is a party thereto and the consummation by the
Contributor or any such Affiliate of the transactions  contemplated  thereby (i)
will not require any Consent except for such Consents the failure of which to be
obtained or made,  would not in the  aggregate  reasonably be expected to have a
Material  Adverse Effect;  and (ii) will not violate (with or without the giving
of  notice or the lapse of time or both),  or  conflict  with,  or result in the
breach or  termination  of any provision of, or constitute a default  under,  or
result  in  the  acceleration  of the  performance  of  the  obligations  of the
Contributor  or any such  Affiliate  under,  or  result  in the  creation  of an
Encumbrance  upon any Assets or a portion of the Contributed  Business  pursuant
to, the  charter or by-laws of the  Contributor  or any such  Affiliate,  or any
indenture,  mortgage,  deed of  trust,  lease,  licensing  agreement,  contract,
instrument or other  agreement to which the Contributor or any such Affiliate is
a party or by which the  Contributor  or any such Affiliate or any of the Assets
held by the  Contributor  or any  such  Affiliate  is  bound,  except  for  such
violations,  conflicts,  breaches,  terminations,   defaults,  accelerations  or
Encumbrances  which would not in the aggregate  reasonably be expected to have a
Material Adverse Effect.

         3.4  Employee Benefits.

         (a)  (i)  Each  of  the  Contributor's   Defined  Benefit  and  Defined
         Contribution  Pension Plans covering employees  ("Employee Plan") is in
         substantial compliance with applicable  requirements  prescribed by any
         and all Legal  Requirements,  including,  but not  limited to the Code,
         except  for  violations  the  occurrence  of  which  would  not  in the
         aggregate  reasonably  be expected to have a Material  Adverse  Effect.
         Each  Employee  Plan that is intended  to be  qualified  under  Section
         401(a) of the Code currently has a favorable  determination letter from
         the  Internal  Revenue  Service as to that Plan's  qualification  under
         Section  401(a) of the Code and nothing has occurred  since the date of
         such letter that could reasonably be expected to cause the loss of such
         qualification.

              (ii)  The Contributor  has  in  all  material  respects  performed
         all  obligations  required to be performed by it under ERISA,  the Code
         and any other applicable Legal Requirements and under the terms of each
         Employee  Plan,  except such failures to perform which would not in the
         aggregate reasonably be expected to have a Material Adverse Effect. The
         Contributor  has  received no written  notice of the  existence  of any
         material  default or  violation by any other party of any of such Legal
         Requirements,  terms or requirements  applicable to any of the Employee
         Plans.

               (iii)  Other  than  routine claims  for benefits, the Contributor
         has not received any written notice of any pending  material  claims or
         lawsuits  which have been  asserted  or  instituted  against any of the
         Employee  Plans,  the assets of the trust or funds  under the  Employee
         Plans,  the sponsor or  administrator  of any of the Employee Plans, or
         against any fiduciary of any of the Employee  Plans with respect to the
         operation of such Plan.

               (iv)  The  Contributor  has  not  received any  written notice of
         any pending  investigation or pending enforcement action by the Pension
         Benefit  Guaranty  Corporation,  the Department of Labor,  the Internal
         Revenue  Service  or any other  Authority  with  respect  to any of the
         Employee Plans.

               (v)   All contributions  required  to be made  under the terms of
         the  Contributor's  Employee  Plans have been timely made.  No Employee
         Plan has an  "accumulated  funding  deficiency"  (within the meaning of
         section 412 of the Code or Section 402 of ERISA).

         (b) All of the  Contributor's  "group health plans" (within the meaning
of Code Section  5000(b)(1))  have been operated in substantial  compliance with
the group health plan continuation coverage requirements of Section 4980B of the
Code and  Sections  601  through 608 of ERISA,  Title XXII of the Public  Health
Service Act and the provisions of the Social Security Act.

         (c) There has been no act or omission by the Contributor that has given
rise to or may give rise to material fines, penalties, taxes, or related charges
under Section  502(c),  (i) or (l) or Section 4071 of ERISA or Chapter 43 of the
Code or the  imposition of a lien  pursuant to Sections  401(a)(29) or 412(n) of
the Code or pursuant to ERISA.

         3.5       Title to Assets; Absence of Liens and Encumbrances.

         (a) The  Contributor  has good and  marketable  title to all of the Fee
Interests described in the Deeds, free and clear of all Encumbrances, except (i)
those  exceptions  contained in the Deeds,  (ii) liens for current taxes not yet
due and  payable  and  mechanics  and  similar  statutory  liens  arising in the
ordinary  course of business,  (iii) liens of employees and laborers for current
wages  not  yet  due;  (iv)  building,  zoning  and  health  regulations  of the
jurisdictions  in which the Assets are located;  and (v) such  imperfections  of
title, easements and Encumbrances, if any, as do not in the aggregate materially
detract  from the value or  materially  interfere  with the use of the Assets as
they are currently  being used or as otherwise  would not reasonably be expected
to have a Material Adverse Effect.

         (b) The  Contributor  is the sole lessee  under the Leases and the sole
party entitled to the Leasehold interests in favor of the lessee thereunder, and
the sole owner of the  improvements  situated on the Leased  Premises,  free and
clear of all Encumbrances affecting the Leaseholds except such Encumbrances,  if
any, as do not in the aggregate  materially detract from the value or materially
interfere  with the use of the Assets or as otherwise  would not  reasonably  be
expected  to  have a  Material  Adverse  Effect.  Neither  Contributor  nor  any
Affiliate  thereof has  received  from or  delivered  to the  lessors  under the
Leaseholds  any written  notice of  termination  or threat of termination of the
respective Leaseholds.  True and complete copies of all written lease agreements
(including any written  amendments or modifications  thereof)  constituting,  or
evidencing the terms of, the Leaseholds have been delivered to the  Partnership.
No material  default or event of default on the part of the  Contributor nor any
Affiliate  thereof under the provisions of any of the  Leaseholds,  and no event
that with the giving of notice or passage of time or both would  constitute such
default or event of default on the part of the Contributor,  has occurred (which
default or event of default has not been cured). Neither the Contributor nor any
Affiliate  thereof has  received  any written  notice from any lessor  under any
Leasehold,  that any  material  default  or event of  default on the part of the
Contributor or such Affiliate as lessee under the provisions of any  Leaseholds,
or that any event  that with the  giving  of notice or  passage  of time or both
would  constitute  such a  default  or an  event of  default  on the part of the
Contributor or any such  Affiliate,  as lessee,  has occurred  (which default or
event of default has not been cured). No material default or event of default on
the part of the lessor under the  provisions of any of such  Leaseholds,  and no
event that with the giving of notice or passage of time or both would constitute
such  default or event of default on the part of any such  lessor,  has occurred
(which default or event of default has not been cured).

         (c) The  Contributor  or an Affiliate  thereof has good title to all of
the  personal  property  purported  to be  owned by it,  free  and  clear of all
Encumbrances,  except  for  liens for  Taxes  not yet due and  payable  and such
Encumbrances,  if any, that do not in the aggregate  materially detract from the
value or materially  interfere with the use of the Assets (as they are currently
being used) or as otherwise  would not reasonably be expected to have a Material
Adverse Effect.

         3.6  Title Matters;  Defects in Improvements.  There are no trespassers
or other adverse  parties in possession on or affecting the Fee Interests or the
Leased  Premises that would  reasonably  be expected to have a Material  Adverse
Effect.  Neither the Contributor nor any Affiliate  thereof has granted and none
of the foregoing is party to any unrecorded  options,  rights of refusal,  sales
contracts  or other  such  contractual  rights  in favor  of any  third  parties
relating to the Fee Interests or the Leased Premises. No written notice has been
received by the Contributor or any Affiliate  thereof from any insurance company
with respect to the Fee Interests or the Leased Premises or by any board of fire
underwriters  claiming any material  defects or  deficiencies  or requiring  the
performance  of any repairs,  replacement,  alteration or other work relating to
the improvements situated thereon (in each case, which have not been cured).

         3.7  Working Capital.   The Contributor has  operated  the  Contributed
Business in the ordinary  course of business  from March 31, 1997 to the Closing
Date such that the Inventory,  Stores  Inventory,  Prepaid Expenses and Accounts
Receivable, as of the Closing Date, are at substantially the same level as would
have existed for the Contributor without regard to the transactions contemplated
by the Master Transaction Agreement.
        
         3.8  Technology and Similar Rights. The Contributor owns or is licensed
to use  all of the  Intellectual  Property,  Licensed  Technology  and  Licensed
Trademarks,  and the  Intellectual  Property,  Licensed  Technology and Licensed
Trademarks   together   constitute   all  relevant   patents,   pending   patent
applications,   invention  disclosures,  copyrights,  software,  trade  secrets,
technical information,  technology, know-how, processes, tradenames, trademarks,
trademark registrations or applications,  copyrights,  copyright applications or
registrations or any derivative  thereof or design used in connection  therewith
necessary for the normal operation and conduct of the Contributed Business as it
is  currently  operated  and  conducted,  except  where the failure to have such
ownership  or  licenses  would not  reasonably  be  expected  to have a Material
Adverse Effect.

         3.9  Government Licenses, Permits and Related Approvals. The Government
Licenses  constitute all those necessary for the normal operation and conduct of
the Contributed Business as it is currently operated and conducted, except where
the failure to have such Government Licenses would not reasonably be expected to
have a Material Adverse Effect.

         3.10  All Necessary Assets. The Assets together  with the rights  under
the Related  Agreements  constitute  all property and other rights  necessary to
enable the  Partnership  to operate  and  conduct  the  Contributed  Business in
substantially  the same manner as it is being operated and conducted on the date
of this  Agreement,  except in all cases where the failure of the Partnership to
acquire such  property or other rights by conveyance or license would not in the
aggregate reasonably be expected to have a Material Adverse Effect.

         3.11 Conduct of Business in Compliance  with Regulatory and Contractual
Requirements.  The  Contributor,  and any  Affiliate  thereof,  is operating and
conducting the  Contributed  Business in compliance  with all  applicable  Legal
Requirements,  rights of  concession,  licenses,  know-how or other  proprietary
rights of others,  the failure to comply with which would reasonably be expected
to have a Material Adverse Effect.

                                    SECTION 4
                REPRESENTATIONS AND WARRANTIES OF THE PARTNERSHIP
                -------------------------------------------------

         The Partnership represents and warrants to the Contributor as follows:

         4.1  Due Organization;  Good Standing and Power.  The  Partnership is a
limited partnership duly formed and validly existing under the laws of the State
of Delaware.  The Partnership  has all partnership  power and authority to enter
into  this  Agreement  and the  other  Related  Agreements  and to  perform  its
obligations  hereunder  and  thereunder.  The  Partnership  is duly  authorized,
qualified  or licensed to do business as a foreign  partnership,  in each of the
jurisdictions  in which its right,  title or interest in or to any asset, or the
conduct  of  its  business,   requires  such  authorization,   qualification  or
licensing,  except  where the  failure to so  qualify  would not have a material
adverse  effect on the ability of the  Partnership  to perform  its  obligations
hereunder or under the Assignment and Assumption Agreements.

         4.2  Authorization and Validity of Agreement.  The execution,  delivery
and  performance  of this  Agreement  and the other  Related  Agreements  by the
Partnership  and  the  consummation  by  the  Partnership  of  the  transactions
contemplated  hereby and  thereby  have been duly  authorized  by all  necessary
partnership  action on the part of the Partnership.  No other partnership action
is necessary for the authorization,  execution,  delivery and performance by the
Partnership of this Agreement, the other Related Agreements and the consummation
by the  Partnership of the  transactions  contemplated  hereby or thereby.  This
Agreement and the other Related Agreements have been duly executed and delivered
by the Partnership and constitute  legal,  valid and binding  obligations of the
Partnership,  enforceable in accordance with their terms, except as the same may
be limited by bankruptcy, insolvency, reorganization,  moratorium and other laws
relating to or  affecting  creditors'  rights  generally  and by general  equity
principles.

         4.3 No Consents  Required;  No Conflict with  Instruments  to which the
Partnership  is a  Party.  The  execution,  delivery  and  performance  of  this
Agreement  and  the  other  Related   Agreements  by  the  Partnership  and  the
consummation by it of the transactions contemplated thereby (i) will not require
any  Consent  except for such  Consents  the  failure of which to be obtained or
made,  would not in the  aggregate  reasonably  be  expected  to have a Material
Adverse Effect on the Partnership's ability to perform its obligations hereunder
or  thereunder,  and (ii) will not violate (with or without the giving of notice
or the  lapse of time or  both),  conflict  with,  or  result  in the  breach or
termination of any provision of, or constitute a default under, or result in the
acceleration of the performance of the obligations of the Partnership under, the
partnership agreement of the Partnership,  or any indenture,  mortgage,  deed of
trust, lease,  licensing agreement,  contract,  instrument or other agreement to
which  the  Partnership  is a party or by which  the  Partnership  or any of its
assets or properties is bound, except for such violations,  conflicts, breaches,
terminations,  defaults, accelerations or liens which would not in the aggregate
reasonably be expected to have a material  adverse  effect on the  Partnership's
ability to perform its obligations hereunder or thereunder.

                                    SECTION 5
                      COVENANTS SUBSEQUENT TO CLOSING DATE
                      ------------------------------------

         5.1  Access to Information. Following the Closing Date, the Partnership
shall afford,  and will cause its Affiliates to afford, to the Contributor,  its
counsel,  accountants  and  other  authorized  representatives,   during  normal
business hours,  reasonable  access to the books,  records and other data of the
Contributed  Business  with respect to the period prior to the Closing Date (and
any  personnel  familiar  therewith)  to the  extent  that  such  access  may be
reasonably  required by the Contributor to facilitate (i) the preparation by the
Contributor  of such tax returns as it may be  required to file with  respect to
the operations of the Assets and the Contributed  Business or in connection with
any audit,  amended  return,  claim for refund or any  proceeding  with  respect
thereto, (ii) the investigation,  litigation and final disposition of any claims
which may have been or may be made against the  Contributor  in connection  with
the  Assets and the  Contributed  Business,  (iii) the  payment of any amount in
connection  with any  liabilities or obligations  which have not been assumed by
the Partnership under this Agreement and (iv) for any other reasonable  business
purpose.  For a  period  of ten  years  after  the date of this  Agreement,  the
Partnership  will not dispose of,  alter or destroy any such books,  records and
other data without giving 90 days' prior notice to the Contributor to permit it,
at its  expense,  to  examine,  duplicate  or  repossess  such  records,  files,
documents and correspondence.

         5.2   Mail or  Other  Communications.  The  Contributor  authorizes and
empowers the  Partnership  on and after the Closing Date to receive and open all
mail received by the  Partnership  relating to the  Contributed  Business or the
Assets  and to deal  with the  contents  of such  communications  in any  proper
manner.  The Contributor  shall promptly  deliver to the Partnership any mail or
other  communication  received by it on and after the Closing Date pertaining to
the Contributed Business or the Assets and any cash, checks or other instruments
of payment to which the Partnership is entitled.  The Partnership shall promptly
deliver to the Contributor any mail or other communication  received by it after
the Closing Date pertaining to the Excluded Assets or Excluded Liabilities,  and
any cash, checks or other instruments of payment in respect of such.

         5.3  Use of Contributor's Trade Name.  Except  as set forth on Schedule
2.2(d),  after the Closing  Date the  Partnership  shall be permitted to use any
items of Inventory or packaging  material,  any sales or promotional  materials,
any  forms or  documents  or any  other  printed  material  that  bears the name
"Lyondell" or other statutory names,  trade names or trademarks,  indications or
descriptions  of which such names or any name similar thereto forms a part until
the earlier to occur of (i) such time as inventory of such materials existing as
of the Closing Date are used, or (ii) two years after the Closing Date.

         5.4  Closing Date  Balance Sheet.   Not later  than 60  days after  the
Closing Date, the  Contributor  shall cause Coopers & Lybrand L.L.P.  to prepare
and deliver to the  Contributor  and the Partnership an audited balance sheet of
the  Contributed  Business as of the Closing  Date (the  "Closing  Date  Balance
Sheet").

         5.5  Payment of Retained Accounts Payable.  The Contributor will retain
all  accounts  payable  including   Retained   Accounts  Payable;   however  the
Partnership,  as payment  agent of the  Contributor,  shall pay such  amounts on
behalf of the  Contributor on a timely basis.  As soon as practicable  following
the end of each month after which such Retained Accounts Payable are paid by the
Partnership,  but in any event within  fifteen days after the end of such month,
each Contributor  will reimburse the Partnership for such payments  attributable
to its Contributed Business.

         5.6  Collection of Accounts Receivable.  The Partnership shall take all
commercially reasonable efforts to collect the Accounts Receivable;  however, to
the extent any Accounts  Receivable  set forth on the Closing Date Balance Sheet
are not collected within 180 days after the Closing Date by the Partnership, the
Contributor will buy such uncollected  Accounts  Receivable from the Partnership
at the  amount set forth on the  Closing  Date  Balance  Sheet.  Collections  on
Accounts  Receivable  shall be applied on a specific  identification  basis. The
Partnership  will  report  monthly  in  writing to  Contributor  on the  amounts
collected  during the  preceding  month,  and shall  provide an aging summary of
uncollected  accounts and a detailed  description of each problem account (45 or
more days overdue).  On reasonable notice to the Partnership,  Contributor shall
have the right to take over the collection process for any problem account.

         5.7  Reimbursement  for  Prepaid  Expenses.  The  Partnership  and  the
Contributor   acknowledge  that  the  Prepaid   Expenses   attributable  to  its
Contributed  Business have been conveyed to the  Partnership  solely in order to
facilitate the timely and efficient transfer of the Contributed  Business to the
Partnership.  Consequently,  the Partnership shall reimburse the Contributor for
the Prepaid  Expenses  associated with its Contributed  Business (other than the
prepaid expenses for "turnaround" costs) within 10 days following the receipt of
the Closing Date Balance Sheet.


                                    SECTION 6
                          SURVIVAL AND INDEMNIFICATION
                          ----------------------------

         6.1  Survival Limitations.   The representations  and warranties of the
parties  hereto  contained  in this  Agreement  or in any  certificate  or other
writing  delivered  pursuant hereto or in connection  herewith shall survive the
Closing  until the date that is 60 months  after the  Closing  Date,  except (i)
Section 3.14, which shall survive until the expiration of the applicable statute
of limitations and (ii) Section 3.5, which shall survive without  limitation and
shall not be merged with the Deeds. No action can be brought with respect to any
breach of any  representation  or warranty  (except with respect to Section 3.5)
pursuant to this  Agreement  unless a written  notice that complies with Section
6.3 has been  delivered  pursuant to such Section 6.3 prior to the expiration of
the survival period applicable to such representation or warranty; provided that
upon the giving of such  notice,  notwithstanding  any other  provision  of this
Agreement the representation and warranty that is the basis of such action shall
continue with respect to such action beyond the time at which the representation
and warranty would otherwise terminate.

         6.2  Indemnification.

         (a) Subject to the other  provisions of this Section 6, the Contributor
hereby agrees,  to the fullest extent permitted by applicable law, to indemnify,
defend and hold harmless the Partnership and its Affiliates and their respective
officers,  directors and employees  from,  against and in respect of any losses,
claims, damages, fines, penalties,  assessments by public agencies,  settlement,
cost or  expenses  (including  costs of defense and  attorneys'  fees) and other
liabilities  (any of the foregoing being a "Liability")  incurred or suffered by
the Partnership or any of its Affiliates,  arising out of, in connection with or
relating to:

                   (i) Any misrepresentation in or breach of the representations
         and  warranties  of the  Contributor  or any of its  Affiliates in this
         Agreement,  the  Assignment  and  Assumption  Agreements,   the  Master
         Intellectual Property Agreement, or the Master Transaction Agreement;

                   (ii) Any failure of the  Contributor or any of its Affiliates
         to  perform  any of its  covenants  or  obligations  contained  in this
         Agreement,  the  Assignment  and  Assumption  Agreements,   the  Master
         Intellectual Property Agreement, or the Master Transaction Agreement;

                   (iii)   Excluded Liabilities;

                   (iv)  Any  Pre-Closing  Contingent  Liability  that is not an
         Assumed Liability; or

                   (v) Any  action by the  Contributor  or its  Affiliates  that
         results  in the  occurrence  of a  "Designated  Event"  as such term is
         defined in the  Contributor's  or its  Affiliates'  1989  Indenture and
         Medium Term Notes described in Schedule 2.5 but only to the extent that
         the  Partnership  incurs an economic  loss  directly as a result of the
         occurrence of the "Designated Event" and in such case the Contributor's
         or its Affiliates'  indemnification obligation is limited to the amount
         of such economic loss;

provided,   however,   that  the  following   limitations  shall  apply  to  the
Contributor's indemnification obligations in clauses (i) and (iv) above:

                   (A)  the  Contributor  shall  not  have  any  indemnification
         obligation under clause (i) and (iv) above for any individual Liability
         unless the amount of such Liability  exceeds  $25,000 (the  "Individual
         Basket") (it being  understood  that all  Liabilities  arising from the
         same event, condition or set of circumstances shall be considered as an
         individual  Liability  for  purposes of such  calculation),  but if the
         amount of such  Liability  exceeds the  Individual  Basket,  the entire
         amount  of  such  Liability,   including  the  first  $25,000  of  such
         Liability, may be the subject of indemnification  hereunder;  provided,
         further,  that the parties agree that the amount of Liability for which
         indemnification  may be  sought  for  breach of any  representation  or
         warranty under clause (i) above shall be calculated taking into account
         the  Individual  Basket  but  without  regard to any  qualification  or
         exception   regarding    materiality   or   Material   Adverse   Effect
         qualification  contained in such  representation  or warranty (it being
         understood   that  such   materiality   or  Material   Adverse   Effect
         qualifications  shall apply for purposes of  determining  whether there
         has  been  such a  breach  in the  first  place,  but  once it has been
         established  that  there is such a  breach,  the  Partnership  shall be
         entitled to indemnity relating back to the first dollar); and

                   (B) to the extent any  misrepresentation  in or breach of the
         representations   and  warranties  of  the  Contributor  results  in  a
         Liability of the  Partnership  in excess of the  Individual  Basket and
         such  Liability   would  also   constitute  a  Pre-Closing   Contingent
         Liability,  such  misrepresentation  or breach  shall be  treated  as a
         Pre-Closing Contingent Liability.

         (b)  NOTWITHSTANDING  ANY OTHER  PROVISION  OF THIS  AGREEMENT,  TO THE
FULLEST EXTENT  PERMITTED BY LAW, NEITHER THE CONTRIBUTOR NOR ANY OF ITS AGENTS,
EMPLOYEES,  REPRESENTATIVES  OR  AFFILIATES  SHALL BE LIABLE FOR  CONSEQUENTIAL,
INCIDENTAL, INDIRECT OR PUNITIVE DAMAGES IN CONNECTION WITH DIRECT CLAIMS BY THE
PARTNERSHIP  (I.E., A CLAIM BY THE PARTNERSHIP THAT DOES NOT SEEK  REIMBURSEMENT
FOR A THIRD  PARTY  CLAIM PAID OR PAYABLE BY THE  PARTNERSHIP)  WITH  RESPECT TO
THEIR  INDEMNIFICATION  OBLIGATIONS  UNDER THIS AGREEMENT  UNLESS ANY SUCH CLAIM
ARISES OUT OF THE FRAUDULENT  ACTIONS OF THE  CONTRIBUTOR.  IN  DETERMINING  THE
AMOUNT OF ANY LOSS, LIABILITY,  OR EXPENSE FOR WHICH THE PARTNERSHIP IS ENTITLED
TO  INDEMNIFICATION  UNDER THIS  AGREEMENT,  THE GROSS  AMOUNT  THEREOF  WILL BE
REDUCED  (BUT NOT  BELOW  ZERO)  BY THE NET  PRESENT  VALUE  OF ANY  CORRELATIVE
INSURANCE  PROCEEDS  ACTUALLY  REALIZED BY THE PARTNERSHIP UNDER POLICIES TO THE
EXTENT THAT THE FUTURE PREMIUM RATE WILL NOT BE INCREASED BY CLAIM EXPERIENCE.

         (c)   Notwithstanding   the   provisions  of  Sections   6.2(a)(i)  and
6.2(a)(iv), it is expressly agreed that the Contributor shall not be required to
indemnify the Partnership  for any Liability  arising out of, in connection with
or  related  to  any  HSE  Claim  to  the  extent  that  the  condition,  event,
circumstance  or other basis for the HSE Claim was exacerbated or accelerated by
the  Partnership.  The  Partnership  shall not be deemed to have  exacerbated  a
condition,  event, circumstance or other basis for an HSE Claim by reason of the
continuance  thereof  after  the  Closing  (i)  under  circumstances  where  the
Partnership  does not know of its  existence and has not breached any legal duty
to have  conducted an  investigation  or inquiry that would have  uncovered  the
matter  or (ii)  under  circumstances  where  the  Partnership  does know of its
existence but is taking commercially reasonable actions to cure the matter or to
otherwise achieve compliance in a commercially reasonable and prudent manner.

         (d) Subject to the other  provisions of this Section 6, the Partnership
hereby indemnifies,  to the fullest extent permitted by law, the Contributor and
its Affiliates against and agrees to hold each of them harmless from any and all
Liability  incurred  or  suffered by the  Contributor  or any of its  Affiliates
arising out of or relating to:

                   (i) Any misrepresentation in or breach of the representations
         and warranties of the  Partnership or the failure of the Partnership to
         perform any of its covenants or obligations contained in this Agreement
         and the Assignment and Assumption Agreements or the Master Intellectual
         Property Agreement;

                   (ii)    Assumed Liabilities; or

                   (iii)  Any  HSE  Claim  to  the  extent  arising  out  of the
         Partnership's exacerbation or acceleration of such HSE Claim.

         (e)  NOTWITHSTANDING  ANY OTHER  PROVISION  OF THIS  AGREEMENT,  TO THE
FULLEST EXTENT  PERMITTED BY LAW, NEITHER THE PARTNERSHIP NOR ANY OF ITS AGENTS,
EMPLOYEES,  REPRESENTATIVES  OR  AFFILIATES  SHALL BE LIABLE FOR  CONSEQUENTIAL,
INCIDENTAL, INDIRECT OR PUNITIVE DAMAGES IN CONNECTION WITH DIRECT CLAIMS BY THE
CONTRIBUTOR  WITH  RESPECT  TO  THEIR  INDEMNIFICATION  OBLIGATIONS  UNDER  THIS
AGREEMENT  UNLESS ANY SUCH CLAIM  ARISES  OUT OF THE  FRAUDULENT  ACTIONS OF THE
PARTNERSHIP.  IN DETERMINING THE AMOUNT OF ANY LOSS,  LIABILITY,  OR EXPENSE FOR
WHICH THE CONTRIBUTOR IS ENTITLED TO INDEMNIFICATION  UNDER THIS AGREEMENT,  THE
GROSS  AMOUNT  THEREOF  WILL BE REDUCED  (BUT NOT BELOW ZERO) BY THE NET PRESENT
VALUE OF ANY CORRELATIVE INSURANCE PROCEEDS ACTUALLY REALIZED BY THE CONTRIBUTOR
UNDER  POLICIES TO THE EXTENT THE FUTURE  PREMIUM  RATE WILL NOT BE INCREASED BY
CLAIM EXPERIENCE.

         (f) The rights provided to the Partnership  pursuant to this Section 6,
as limited  by and  subject to the  provisions  of this  Section 6, shall be the
Partnership's  sole  remedy  for breach of  representation  and  warranty  by or
covenant or obligation of the Contributor  under this Agreement,  the Assignment
and Assumption  Agreements and the Master Intellectual  Property Agreement.  The
rights provided to the Contributor pursuant to this Section 6, as limited by and
subject to the  provisions  of this Section 6, shall be the  Contributor's  sole
remedy for breach of representation and warranty by or covenant of obligation of
the Partnership under this Agreement,  the Assignment and Assumption  Agreements
and the Master Intellectual Property Agreement.

         6.3   Procedures.

         (a)  Any  Person  seeking   indemnification   under  Section  6.2  (the
"Indemnified  Party")  agrees to give prompt written notice to the party against
whom  indemnity  is sought (the  "Indemnifying  Party") of the  assertion of any
claim that does not involve a Third Party Claim,  which notice shall describe in
reasonable  detail the nature of the claim, an estimate of the amount of damages
attributable  to  such  claim  to the  extent  feasible  and  the  basis  of the
Indemnified  Party's request for  indemnification  under this Agreement.  If the
Indemnifying  Party  disputes such claim and such dispute is not resolved by the
parties, such dispute shall be resolved in accordance with Section 7.9.

         (b) If an  Indemnified  Party is  notified of a Third Party Claim which
may give rise to a claim for  indemnification  against  any  Indemnifying  Party
under this  Section,  then the  Indemnified  Party  shall  promptly  notify each
Indemnifying  Party  thereof in writing  (including  copies of all papers served
with  respect to such  Third  Party  Claim),  which  notice  shall  describe  in
reasonable detail the nature of the Third Party Claim, an estimate of the amount
of damages  attributable to the Third Party Claim to the extent feasible and the
basis  of  the  Indemnified  Party's  request  for  indemnification  under  this
Agreement;  provided  that any  failure  to timely  give such  notice  shall not
relieve the  Indemnifying  Party of any of its obligations  under this Section 6
except to the extent that such failure  prejudices  or impairs,  in any material
respect, any of the rights or obligations of the Indemnifying Party.

         (c) Any  Indemnifying  Party may, and at the request of the Indemnified
Party  shall,  participate  in and  control the defense of the Third Party Claim
with counsel of its choice reasonably satisfactory to the Indemnified Party. The
Indemnified  Party shall have the right to employ  separate  counsel in any such
action and to participate in the defense  thereof,  but the fees and expenses of
such  counsel  shall be at the expense of the  Indemnified  Party unless (i) the
employment   thereof  has  been  specifically   authorized  in  writing  by  the
Indemnifying Party, (ii) the Indemnifying Party failed to assume the defense and
employ counsel or failed to diligently prosecute or settle the Third Party Claim
or (iii) there shall exist or develop a conflict that would  ethically  prohibit
counsel to the Indemnifying  Party from  representing the Indemnified  Party. If
requested by the Indemnifying  Party, the Indemnified  Party agrees to cooperate
with the Indemnifying  Party and its counsel in contesting any Third Party Claim
that the Indemnifying Party elects to contest, including, without limitation, by
making any  counterclaim  against the person or entity asserting the Third Party
Claim or any cross-complaint  against any person or entity, in each case only if
and to the extent that any such counterclaim or cross-complaint  arises from the
same  actions or facts giving rise to the Third Party  Claim.  The  Indemnifying
Party  shall  be the  sole  judge  of the  acceptability  of any  compromise  or
settlement of any claim,  litigation or proceeding in respect of which indemnity
may be sought  hereunder,  provided  that the  Indemnifying  Party will give the
Indemnified   Party  reasonable  prior  written  notice  of  any  such  proposed
settlement  or  compromise  and will not consent to the entry of any judgment or
enter into any  settlement  with  respect to any Third Party  Claim  without the
prior written consent of the Indemnified  Party, which shall not be unreasonably
withheld.  The  Indemnifying  Party (if the  Indemnified  Party is  entitled  to
indemnification  hereunder)  shall  reimburse  the  Indemnified  Party  for  its
reasonable out of pocket costs incurred with respect to such cooperation.

         (d) If the  Indemnifying  Party  fails to assume the defense of a Third
Party Claim within a reasonable  period after receipt of written notice pursuant
to the first sentence of subparagraph (c), or if the Indemnifying  Party assumes
the defense of the  Indemnified  Party  pursuant to  subparagraph  (c) but fails
diligently  to prosecute or settle the Third Party Claim,  then the  Indemnified
Party  shall  have the  right to  defend,  at the sole cost and  expense  of the
Indemnifying  Party (if the  Indemnified  Party is entitled  to  indemnification
hereunder),  the  Third  Party  Claim  by  all  appropriate  proceedings,  which
proceedings shall be promptly and vigorously prosecuted by the Indemnified Party
to a final conclusion or settled.  The Indemnified Party shall have full control
of such defense and proceedings;  provided that the Indemnified  Party shall not
settle such Third Party Claim  without the written  consent of the  Indemnifying
Party, which consent shall not be unreasonably  withheld. The Indemnifying Party
may participate in, but not control, any defense or settlement controlled by the
Indemnified  Party pursuant to this Section,  and the  Indemnifying  Party shall
bear its own costs and expenses with respect to such participation.

         (e)  Notwithstanding  the other  provisions of this Section 6.3, if the
Indemnifying  Party disputes its potential  liability to the  Indemnified  Party
under  this  Section  6.3  and if such  dispute  is  resolved  in  favor  of the
Indemnifying  Party,  the  Indemnifying  Party shall not be required to bear the
costs and expenses of the Indemnified  Party's defense  pursuant to this Section
6.3 or of the  Indemnifying  Party's  participation  therein at the  Indemnified
Party's  request,  and the Indemnified  Party shall  reimburse the  Indemnifying
Party in full for all costs  and  expenses  of the  litigation  concerning  such
dispute.  If a dispute  over  potential  liability  is  resolved in favor of the
Indemnified  Party, the Indemnifying Party shall reimburse the Indemnified Party
in full for all costs of the litigation concerning such dispute.

         (f) After it has been  determined,  by  acknowledgment,  agreement,  or
ruling of court of law, that an Indemnifying  Party is liable to the Indemnified
Party under this Section 6, the Indemnifying Party shall pay or cause to be paid
to the Indemnified Party the amount of the Liability within ten business days of
receipt by the Indemnifying Party of a notice reasonably itemizing the amount of
the  Liability  but  only  to  the  extent  actually  paid  or  suffered  by the
Indemnified Party.

         (g) In the event a Third Party Claim is brought in which the  liability
as between the  Partnership and the Contributor is alleged to be joint (it being
agreed that any Third Party Claim related to a Pre-Closing  Contingent Liability
shall be deemed joint) or in which the entitlement to indemnification under this
Section 6 has not been  determined,  the Partnership  and the Contributor  shall
cooperate in the joint defense of such Third Party Claim and shall offer to each
other such  assistance  as may  reasonably  be  requested in order to ensure the
proper and adequate  defense of any such  matter.  Such joint  defense  shall be
under the general  management and  supervision of the party which is expected to
bear the greater share of the  liability,  unless  otherwise  agreed;  provided,
however,  that neither party shall settle or  compromise  any such joint defense
matter without the consent of the other, which consent shall not be unreasonably
withheld or delayed. Any uninsured costs of such joint defense shall be borne as
the parties may agree, provided, however, that in the absence of such agreement,
the defense costs shall be borne by the party  incurring  such costs;  provided,
further,   that,   if  it  is   determined   that  one  party  was  entitled  to
indemnification  under this Section 6, the other party shall reimburse the party
entitled to  indemnification  for all of its costs  incurred in connection  with
such defense.

         6.4  Subrogation.  In the event  of  any  payment  by  an  Indemnifying
Party to an Indemnified Party in connection with any Liability, the Indemnifying
Party shall be  subrogated  to and shall  stand in the place of the  Indemnified
Party as to any events or  circumstances  in  respect  of which the  Indemnified
Party may have any right or claim against any third party relating to such event
or indemnification.  The Indemnified Party shall cooperate with the Indemnifying
Party in any reasonable manner in prosecuting any subrogated claim.

         6.5  Claims for HSE Work.  Notwithstanding the other provisions of this
Section  6,  in the  case  of any  assertion,  claim  or  demand  requiring  the
performance  of  investigatory,   removal  or  remedial  work  with  respect  to
(environmental  conditions,  HSE  Laws or  Chemical  Substances  for  which  the
Partnership may seek  indemnification,  the Partnership  shall have the right to
conduct and control such work provided (i) it uses its good faith,  commercially
reasonable  efforts to achieve the Lowest Cost Response and (ii) it provides the
Contributor  with the opportunity to: (A) review and comment upon any work plans
for any remedial action prior to  finalization  and  implementation;  (B) attend
meetings  with  regulators  concerning  the  remedial  action;  and  (C)  have a
representative present during the performance of any remedial action.

         6.6  EXTENT OF  INDEMNIFICATION.  WITHOUT  LIMITING  OR  ENLARGING  THE
SCOPE OF THE  INDEMNIFICATION,  RELEASE  AND  ASSUMPTION  OBLIGATIONS  SET FORTH
HEREIN,  TO THE FULLEST EXTENT  PERMITTED BY LAW, AN INDEMNIFIED  PARTY SHALL BE
ENTITLED TO  INDEMNIFICATION  HEREUNDER  IN  ACCORDANCE  WITH THE TERMS  HEREOF,
REGARDLESS  OF  WHETHER  THE   INDEMNIFIABLE   LOSS  GIVING  RISE  TO  ANY  SUCH
INDEMNIFICATION  OBLIGATION IS THE RESULT OF THE SOLE, GROSS,  ACTIVE,  PASSIVE,
CONCURRENT  OR  COMPARATIVE  NEGLIGENCE,  STRICT  LIABILITY  OR  OTHER  FAULT OR
VIOLATION OF ANY LAW OF OR BY ANY SUCH INDEMNIFIED PARTY. THE PARTIES AGREE THAT
THIS STATEMENT CONSTITUTES A CONSPICUOUS LEGEND.

                          -----------------------------


The  following  liabilities  related to (i) the  operations  of the  Contributed
Business or (ii) employees who will become employees of the Partnership:

                                   Schedule 3

                               Disclosure Schedule
                               -------------------

         The  Contributor  makes  no  exceptions  to  the   representations  and
warranties  made by it in Section 3 of this  Agreement  except for the following
exception to its representations made in Section 3.4 of this Agreement:

                  The Contributor has received a letter from the Pension Benefit
Guaranty  Corporation  (the "PBGC") dated October 31, 1997  expressing a concern
that the actions  contemplated  by the Agreement  would increase the risk to the
PBGC relating to the Lyondell Retirement Plan for Non-Represented  Employees. In
that letter,  the PBGC noted that it could seek to  involuntarily  terminate the
Plan prior to the Closing Date if it determined that the transaction would cause
the risk to the PBGC to increase unreasonably.  The letter went on to state that
this measure  would be viewed as a last resort and that the PBGC would prefer to
enter into a consensual agreement to protect the Plan.

                  The  Contributor  has  provided  the  PBGC  with   information
explaining  the  transaction  pursuant to a  Confidentiality  Agreement with the
PBGC. In addition,  the  Contributor  has met with  representatives  at the PBGC
regarding the  transaction  and those  representatives  have suggested  possible
consensual  arrangements  that  could be  acceptable  to the PBGC in lieu of any
attempt to terminate the Plan.

                                   Appendix A

                          Dispute Resolution Procedures
                          -----------------------------


         (1) Binding and Exclusive Means. The dispute resolution  provisions set
forth in this Appendix A shall be the binding and exclusive means to resolve all
disputes arising under this Agreement (each a "Dispute").

         (2) Standards and Criteria. In resolving any Dispute, the standards and
criteria  for  resolving  such dispute  shall,  unless the  Contributor  and the
Partnership in their discretion jointly stipulate otherwise,  be as set forth in
Appendix 1 to this Appendix A.

         (3) ADR and Binding  Arbitration  Procedures.  If a Dispute arises, the
following procedures shall be implemented:

         (a)  The  Indemnifying  Party  may  at  any  time  invoke  the  dispute
resolution  procedures  set  forth  in  this  Appendix  A as to any  Dispute  by
providing  written notice of such action to the  Indemnified  Party,  who within
five  Business  Days after such  notice  shall  schedule a meeting to be held in
Houston,  Texas between the parties.  The meeting shall occur within 10 Business
Days after  notice of the meeting is delivered to the  Indemnifying  Party.  The
meeting   shall  be   attended   by   representatives   of  each  party   having
decision-making   authority  regarding  the  Dispute  as  well  as  the  dispute
resolution process and who shall attempt in a commercially  reasonable manner to
negotiate a resolution of the Dispute.

         (b)  The   representatives   of  the  parties  shall   cooperate  in  a
commercially  reasonable  manner and shall explore  whether  techniques  such as
mediation,  minitrials,  mock trials or other techniques of alternative  dispute
resolution might be useful. In the event that a technique of alternative dispute
resolution is so agreed upon, a specific  timetable and completion  date for its
implementation  shall also be agreed upon. The representatives  will continue to
meet and discuss settlement until the date (the "Interim Decision Date") that is
the earliest to occur of the following events: (i) an agreement shall be reached
by the parties  resolving the Dispute;  (ii) one of the parties shall  determine
and notify the other party in writing that no agreement resolving the Dispute is
likely to be reached;  (iii) if a technique of alternative dispute resolution is
agreed upon, the completion date therefor shall occur without the parties having
resolved  the  Dispute;  or (iv) if another  technique  of  alternative  dispute
resolution is not agreed upon,  two full meeting days (or such other time period
as may be agreed  upon) shall  expire  without the parties  having  resolved the
Dispute.

         (c) If, as of the Interim Decision Date, the parties have not succeeded
in  negotiating  a resolution  of the dispute  pursuant to  subsection  (b), the
parties shall proceed under subsection (d).

         (d) The parties  shall jointly  appoint a Neutral.  If the parties have
been  unable to agree upon such  appointment  within 30 days  after the  Interim
Decision Date, then such Neutral,  upon the application of either of the parties
shall be  appointed  within  10 days of the  filing of such  application  by the
Center for Public Resources, or if such appointment is not so made promptly then
promptly  thereafter by the American  Arbitration  Association in  Philadelphia,
Pennsylvania,  or if such  appointment  is not so made  promptly  then  promptly
thereafter  by  the  senior  United  States  District  Court  judge  sitting  in
Wilmington,  Delaware.  The fees of the  Neutral  shall be paid  equally  by the
parties except that the Neutral shall have discretion to award fees.

         (e) In  consultation  with the Neutral,  the parties shall agree upon a
binding  schedule  and  procedure  (which  procedure  may have  been  previously
discussed  under  subsection (b)) to be used as a means to resolve or to attempt
to resolve  Dispute,  with the Neutral  making the  decision as to the  schedule
and/or procedure if the parties have been unable to agree on any of such matters
within 20 days after the initial selection of the Neutral.  The parties agree to
participate  in a  commercially  reasonable  manner  in  the  procedure  to  its
conclusion as determined  by the Neutral.  If the parties are not  successful in
resolving the Dispute through the procedure  described  above,  then the parties
agree that (i) the Neutral shall act as the arbitrator in a binding  arbitration
in accordance with the American Arbitration Association rules and shall render a
decision  and (ii)  judgment  upon the  decision  rendered by the Neutral may be
entered in any court having jurisdiction.

         (4)  Continuation  of Business.  Notwithstanding  the  existence of any
Dispute or the  pendency  of any  procedures  pursuant  to this  Appendix A, the
parties agree and undertake  that all payments not in dispute shall  continue to
be made and all obligations not in dispute shall continue to be performed.

                                   ----------


         (a) First priority shall be given to maximizing the  consistency of the
resolution of the Dispute with the  satisfaction  of all express  obligations of
the parties and their Affiliates as set forth in the Agreement.

         (b) Second  priority  shall be given to  resolution of the Dispute in a
manner  which best  achieves  the  objectives  of the  business  activities  and
arrangements under the Agreement and permits the parties to realize the benefits
intended to be afforded thereby.

         (c) Third priority shall be given to such other matters, if any, as the
parties  or  the  Neutral   shall   determine  to  be   appropriate   under  the
circumstances.

                                ----------------


         This Parent Agreement (this  "Agreement") is made as of this 1st day of

("Lyondell"),  Millennium Chemicals Inc., a Delaware  corporation  ("Millennium"
and,  together with  Lyondell,  the  "Parents")  and Equistar  Chemicals,  LP, a

         WHEREAS,  Lyondell and Millennium  entered into the Master  Transaction
Agreement  dated  as of July 25,  1997,  as  amended  (the  "Master  Transaction
Agreement").

         WHEREAS, pursuant to the terms of the Master Transaction Agreement, the

<PAGE>


                                                     
         WHEREAS, this Agreement is essential to the consummation of the closing
pursuant  to  the  Master  Transaction  Agreement  and  the  entering  into  and
effectiveness  of the  Other  Agreements,  and  each  of  the  parties  to  such
agreements is relying on this Agreement in connection with entering into each of
the Other Agreements.

         WHEREAS, in order to induce the parties thereto to enter into the Other
Agreements,  each Parent is willing, solely for the benefit of the Beneficiaries
(as  defined  below in  Section  1.11)  and their  successors  and  assigns,  to
guarantee the performance by its Affiliated  Obligors of the obligations of such
Affiliated Obligors as set forth in this Agreement.

         WHEREAS,  each  Parent is willing to subject  the Partner Sub Stock (as
defined  herein)  to  certain  restrictions  on  transfer,  as set forth in this
Agreement.

         NOW  THEREFORE,  in,  consideration  of the  foregoing  and the  mutual
promises and covenants of the parties  hereto,  the Parents and the  Partnership
hereby agree as follows:


                                    SECTION 1
                            GUARANTEE OF OBLIGATIONS
                            ------------------------

         1.1  Guarantee.  Each Parent  hereby  unconditionally,  absolutely  and
irrevocably  guarantees,  undertakes and promises to cause, as herein  provided,
the due and  punctual  payment  and  the  full  and  prompt  performance  by its
Affiliated  Obligors  of all of the  amounts to be paid and all of the terms and
provisions  to be  performed  or  observed  by or on the part of its  Affiliated
Obligors  under the Other  Agreements in accordance  with the terms thereof (all
such terms and  provisions as now or hereafter in existence  being  collectively
called the "Obligations") as follows:  in the event that its Affiliated Obligors
shall  fail in any manner  whatsoever  to pay,  perform or observe  any of their
Obligations,  when and as the same shall be  required to be paid,  performed  or
observed under the terms of the Other  Agreements,  such Parent will itself duly
and punctually  pay, or fully and promptly  perform or observe,  as the case may
be, such Obligations, or cause the same to be duly and punctually paid, or fully
and promptly  performed or observed,  in each case as if such Parent were itself
the obligor with respect to such Obligations under the Other Agreements. Insofar
as this Section 1.1 relates to the  obligations  of an Affiliated  Obligor under
the  Partnership  Agreement  and except as set forth in Section  1.2,  no Parent
shall be required to make, or cause a Partner Sub to make, any  contribution  to
the Partnership that such Partner Sub is not otherwise required to make pursuant
to the terms of Section 2.3, 2.4, or 12.2(d)(ii) of the  Partnership  Agreement.
Insofar  as this  Section  1.1  applies  to  Other  Agreements  other  than  the
Partnership  Agreement,  the term  "Affiliated  Obligors"  will not  include the
Partnership nor any partner in the Partnership in its capacity as such.

         1.2  Guarantee  Regarding  Interested  Owner  Agreements.  Each  Parent
acknowledges   that  the  Partnership   Agreement  sets  forth   definitions  of
"Conflicted   Partner"  and   "Nonconflicted   Partner,"  and  provides  that  a
Nonconflicted  Partner has certain  exclusive  rights to control the Partnership
with  respect  to any  Conflict  Circumstance  (as  defined  in the  Partnership
Agreement);  and  accordingly,  without  limiting  the rights of its Partner Sub
under  Section 6.8 of the  Partnership  Agreement,  each Parent hereby agrees to
cause its Partner Sub (i) to cause the  Partnership to pay,  perform and observe
all of the  Obligations  to be paid,  performed or observed by or on the part of
the  Partnership  under  the  Other  Agreements,  in  accordance  with the terms
thereof, to the extent that such Partner Sub is the Nonconflicted Partner and is
thereby  entitled  to cause the  payment,  performance  and  observance  of such
Obligations  and (ii) to abide by its obligations as the  Nonconflicted  Partner
with respect to any Conflict  Circumstance  in accordance  with the terms of the
Partnership Agreement applicable thereto; provided,  however, that each Parent's
responsibility  under this Section 1.2 for a failure of the  Partnership to pay,
perform or observe its obligations  under the Other  Agreements shall be limited
to the  circumstances in which the  Partnership's  failure to so pay, perform or
observe its obligations under the Other Agreements was directly caused by an act
or failure to act of its Partner Sub;  provided,  further,  that nothing in this
Section 1.2 shall require a Parent to make or cause such Partner Sub to make any
contribution to the Partnership that such Partner Sub is not otherwise  required
to make  pursuant  to  Section  2.3,  2.4,  or  12.2(d)(ii)  of the  Partnership
Agreement.

         1.3 No Demand or Notice.  It shall not be a condition to the guarantees
and  agreements  set  forth  in  Sections  1.1  and  1.2  above  (together,  the
"Guarantee")  that a Beneficiary  shall have first made any request of or demand
upon,  or given  any  notice  of the  occurrence  of a  default  under the Other
Agreements or any other notice  whatsoever  to, either Parent or its  Affiliated
Obligors or any other Person,  or shall have instituted any action or proceeding
against any Affiliated Obligor or any other Person in respect thereof,  or shall
have  joined any  Affiliated  Obligor or the  Partnership  in any such action or
proceeding.  A Beneficiary in asserting the benefit of the Guarantee  shall give
prompt  notice to a Parent of any  failure  by its  Affiliated  Obligors  or the
Partnership to pay, perform or observe any Obligation;  provided,  however, that
any  failure,  delay or defect in the giving of such  notice  shall not alter or
affect the Guarantee under this Agreement.

         1.4 Waiver of Resort to Security.  Each Parent further agrees that this
Agreement,  insofar as it  constitutes  a  guarantee  of  monetary  Obligations,
constitutes  a guarantee  of payment  when due and not of  collection,  and each
Parent  waives any right to require as a  condition  to its  Guarantee  that any
resort be had by a  Beneficiary  to any  security  held for the  payment  of any
Obligations.

         1.5 No  Discharge.  The  Guarantee  is and shall  remain  absolute  and
unconditional irrespective of any circumstance that might otherwise constitute a
legal or equitable discharge of a surety or guarantor,  as the case may be, with
respect to its Guarantee.

         1.6 Waivers by the Parent.  Each Parent hereby waives,  with respect to
the Guarantee but without  prejudice to the rights of the parties to the several
Other   Agreements,   any  notice  of  acceptance  of  this  Agreement,   grace,
presentment,  demand,  protest,  notice of the occurrence of a default under the
Other  Agreements and any other notice of any kind  whatsoever and promptness in
making any claim or demand hereunder. The Guarantee shall not be affected by (i)
the  failure of a  Beneficiary  to assert any claim or demand or to enforce  any
right or remedy  under the  provisions  of any of the  Other  Agreements  or any
agreement related thereto or otherwise,  (ii) any extension or renewal of any of
the Other  Agreements or any agreement  related  thereto,  (iii) any rescission,
waiver,  amendment or  modification  of any of the terms or provisions of any of
the Other  Agreements or of any agreement  related thereto,  including,  without
limitation, any change in the time, manner or place of payment or performance of
any of the obligations  under the Other  Agreements,  or (iv) the release of any
security held for payment of any Obligations.

         1.7 No Reduction.  The Guarantee shall not be subject to any reduction,
limitation,  impairment  or  termination  for  any  reason,  including,  without
limitation, any claim of waiver, release,  surrender,  alteration or compromise,
and shall not be subject to any defense or set-off, counterclaim,  recoupment or
termination whatsoever, except as provided in Section 1.10.

         1.8  Enforcement.  Notwithstanding  anything herein to the contrary,  a
Beneficiary  may  proceed to enforce the  Guarantee  without  first  pursuing or
exhausting  any right or remedy that it or any of its  successors or assigns may
have against any Affiliated Obligor or either Parent or any other person.

         1.9  Continued  Effectiveness.  The  Guarantee  shall  continue  to  be
effective or be reinstated,  as the case may be, if at any time payment,  or any
part thereof,  of any  Obligation of an Affiliated  Obligor is rescinded or must
otherwise be restored or returned by the Person  receiving such payment upon the
insolvency, bankruptcy or reorganization of an Affiliated Obligor, all as though
such payment or part thereof had not been made.

         1.10  Certain  Defenses.  Nothing  herein is intended to deny to either
Parent,  and it is expressly  agreed that each Parent shall have and may assert,
any and all of the  defenses,  set-offs,  counterclaims  and other rights (other
than those relating to insolvency,  bankruptcy or reorganization as described in
Section 1.9) with regard to any  Obligations  that its  Affiliated  Obligors may
possess except any defense its Affiliated  Obligors may possess relating to lack
of validity or  enforceability of the Other Agreements or any other agreement or
instrument  relating thereto as against its Affiliated Obligors arising from the
defective  incorporation  or  other  defective  organization  of its  Affiliated
Obligors,  their  lack  of  qualification  to  do  business  in  any  applicable
jurisdiction or their defective corporate or other  organizational  authority to
enter into, deliver or perform the Other Agreements.

         1.11  Parties in  Interest.  This  Agreement  shall inure solely to the
benefit  of the  Beneficiaries,  each  of whom  has the  right  to  enforce  the
Guarantee  against  the  Parents,  and  nothing  in this  Agreement,  express or
implied,  is  intended  to or shall  confer  upon any other  Person any  rights,
benefits  or  remedies  of any  nature  whatsoever  under or by  reason  of this
Agreement.  As used in this Agreement,  "Beneficiaries" shall mean (i) as to any
obligations  of Millennium  hereunder,  except for its  obligations  pursuant to
Section 1.1 hereof with respect to the Partnership  Agreement,  the Partnership,
Lyondell and the Lyondell  Affiliated  Obligors,  (ii) as to any  obligations of
Lyondell  hereunder,  except for its obligations  pursuant to Section 1.1 hereof
with respect to the Partnership Agreement,  the Partnership,  Millennium and the
Millennium Affiliated Obligors, and (iii) as to any obligations of Millennium or
Lyondell  pursuant  to  Section  1.1  hereof  with  respect  to the  Partnership
Agreement, Lyondell and Millennium, respectively. As used in this Agreement, the
term Parent  includes any successor or  transferee  of the Parent,  and the term
Affiliated  Obligors  includes any successor to or transferee of the  Affiliated
Obligors'  interest in the  Partnership  permitted  pursuant to the  Partnership
Agreement.


                                    SECTION 2
                     OWNERSHIP AND BUSINESS OF PARTNER SUBS
                     --------------------------------------

         2.1  Restrictions on Transfer and Pledge of Partner Sub Stock. (a) Each
Parent  agrees that except as  otherwise  provided  below in this Section 2.1 or
Section 2.2 or with the written  consent of the other  Parent (or any  Successor
Parent, as defined in Section 2.1(d)),  which consent may be granted or withheld
in such Parent's sole  discretion,  it will not, in any transaction or series of
transactions,  directly or  indirectly,  (i) sell,  assign or  otherwise  in any
manner  dispose of, whether by act, deed,  merger or otherwise  ("Transfer")  or
(ii) mortgage, pledge, encumber or create or suffer to exist any pledge, lien or
encumbrance  upon or  security  interest in  ("Pledge"),  all or any part of the
capital stock (including any securities  convertible into or exchangeable for or
carrying any rights to  purchase,  subscribe  for or otherwise  acquire any such
capital  stock) of its Partner  Subs  (collectively,  the  "Partner Sub Stock").
(Each of the defined terms "Transfer"and  "Pledge" is used herein both as a noun
and as a verb.) Any  attempt by a Parent to  Transfer or Pledge all or a portion
of its Partner Sub Stock in violation of this Agreement  shall be void ab initio
and shall not be  effective  to transfer  such  Partner Sub Stock or any portion
thereof. The Partnership  Agreement contains provisions relating to the Transfer
and Pledge of the Partner Subs' direct interests in the Partnership.

         (b) The Parent  agrees  that all  certificates  representing  shares of
Partner Sub Stock,  whether currently owned or hereafter  acquired,  shall carry
the  following  legend,  which  legend each Parent  agrees to cause to be placed
thereon and to cause to remain thereon as long as such shares are subject to the
restrictions of this Agreement:

         THE SALE, ASSIGNMENT,  PLEDGE OR OTHER TRANSFER OR HYPOTHECATION OF THE
         STOCK   REPRESENTED   BY  THIS   CERTIFICATE   IS  SUBJECT  TO  CERTAIN
         RESTRICTIONS  PURSUANT TO AND MAY NOT BE EFFECTED  EXCEPT IN ACCORDANCE
         WITH THE PROVISIONS OF AN AGREEMENT BINDING UPON THE OWNER OF THE STOCK
         REPRESENTED  HEREBY.  THE OWNER OR ISSUER  WILL  FURNISH A COPY OF SUCH
         AGREEMENT TO ANY PROPOSED  TRANSFEREE  OR PLEDGEE  WITHOUT  CHARGE UPON
         REQUEST.

         (c)  Without  the need for the  consent of any  Person,  any Parent may
Transfer its Partner Sub Stock to any wholly-owned Affiliate of such Parent.

         (d) Each Parent may Transfer all (but not less than all) of its Partner
Sub Stock if such  Transfer is in connection  with (i) a merger,  consolidation,
conversion or share exchange of such Parent or (ii) a sale or other  disposition
of (x) the Partner Sub Stock plus (y) other assets  representing  at least fifty
percent  (50%) of the book value of such Parent's  assets  excluding the Partner
Sub Stock,  as reflected on its most recent audited  consolidated  (or combined)
financial  statements;  provided,  however,  the ultimate  parent  entity of the
acquiring,   succeeding  or  surviving  entity  in  any  such  transaction  (the
"Successor  Parent") (i) shall  succeed to and be  substituted  for such Parent,
with the same  effect as if it had been named  herein and (ii) shall  execute an
instrument  wherein such  ultimate  parent entity shall agree to be bound by the
obligations of such Parent under this  Agreement,  with the same effect as if it
had been named  herein,  whereupon,  unless such Parent shall become a direct or
indirect  subsidiary of the  Successor  Parent,  such Parent shall  thereupon be
released from all obligations hereunder.

         (e) Nothing in this  Agreement  shall prevent the Transfer or Pledge of
the capital stock,  equity ownership  interests or other securities of a Parent,
and no such Transfer or Pledge of securities  issued by a Parent shall be deemed
to constitute a Transfer or Pledge of Partner Sub Stock hereunder.

         (f) Each  Parent may Pledge all (but not less than all) of its  Partner
Sub Stock to any one or more Approved Lenders; provided that the Pledge shall be
evidenced by an instrument,  reasonably satisfactory to the Partnership, wherein
the  Approved  Lender  receiving  such Pledge shall agree that in the event such
Approved  Lender  obtains a right of  foreclosure  on such Parent's  Partner Sub
Stock,  such Approved  Lender will foreclose on the Partner Sub Stock of each of
such  Parent's  Partner  Subs equally so that such  Approved  Lender will in all
events hold equal portions of Partner Sub Stock of LG Partner and Lyondell LP or
Millennium GP and Millennium LP, as the case may be. An "Approved  Lender" shall
be any bank, insurance company,  investment bank or other financial  institution
that is regularly engaged in the business of making loans.

         2.2      Right of First Option.

                  (a) Without the consent of the other  Parent,  neither  Parent
may  Transfer  less than all of its Partner Sub Stock.  Unless such  Transfer is
otherwise permitted by Section 2.1, any Parent desiring to Transfer (pursuant to
a cash sale) all of its  Partner  Sub Stock (the  "Selling  Parent")  shall give
written notice (the "Initial  Notice") to the  Partnership  and the other Parent
(the "Offeree  Parent")  stating that the Selling Parent desires to Transfer its
Partner  Sub Stock and stating  the cash  purchase  price and all other terms on
which it is willing to sell (the "Offer  Terms").  Delivery of an Initial Notice
shall constitute the irrevocable offer of the Selling Parent to sell its Partner
Sub Stock to the Offeree Parent hereunder.

                  (b) The Offeree  Parent shall have the option,  exercisable by
delivering  written  notice (the  "Acceptance  Notice") of such  exercise to the
Selling  Parent  within 45 days of the date of the Initial  Notice,  to elect to
purchase  all of the Partner Sub Stock of the Selling  Parent on the Offer Terms
described  in the Initial  Notice.  The  Acceptance  Notice shall set a date for
closing  the  purchase,  such  date to be not less than 30 nor more than 90 days
after delivery of the Acceptance Notice; provided that such time period shall be
subject to extension as  reasonably  necessary (up to a maximum of an additional
120 days after such 90 day period) in order to comply with any applicable filing
and  waiting  period   requirements   under  the   Hart-Scott-Rodino   Antitrust
Improvements  Act. The closing shall be held at the Partnership's  offices.  The
purchase price for the Selling  Parent's Partner Sub Stock shall be paid in cash
delivered at the closing.  The purchase shall be consummated by appropriate  and
customary documentation  (including the giving of representations and warranties
substantially  similar to those set forth in  Sections  2.1  through  2.4 of the
Master  Transaction  Agreement  and  customary  representations  and  warranties
regarding the Selling Parent's title to its Partner Sub Stock).

                  (c) If the  Offeree  Parent  does not  elect to  purchase  the
Selling  Parent's  Partner  Sub Stock  within 45 days  after the  receipt of the
Initial Notice, the Selling Parent shall have a further 180 days during which it
may, subject to Sections 2.2(d) and (e),  consummate the sale of its Partner Sub
Stock to a third  party  purchaser  at a purchase  price and on such other terms
that are no more favorable to such  purchaser than the Offer Terms.  If the sale
is not completed within such further 180-day period, the Initial Notice shall be
deemed to have  expired and a new notice and offer shall be required  before the
Selling Parent may make any Transfer of its Partner Sub Stock.

                  (d) Before the Selling Parent may consummate a Transfer of its
Partner  Sub  Stock to a third  party in  accordance  with this  Agreement,  the
Selling Parent shall demonstrate to the Partnership that such proposed purchaser
(or the Person  willing to serve as its  guarantor  as  contemplated  by Section
2.2(f)) has outstanding  indebtedness  that is rated  investment grade by either
Moody's  Investor  Services  Inc. or Standard & Poor's  Corporation,  or if such
proposed purchaser (or such other Person) has no rated indebtedness outstanding,
such Person shall  provide an opinion from a  nationally  recognized  investment
banking firm that it could be reasonably expected to obtain such a rating.

                  (e) Notwithstanding  the foregoing  provisions of this Section
2.2, a Parent may Transfer its Partner Sub Stock (other than pursuant to Section
2.1) only if all of the following occur:

                           (i) The  Transfer  is  accomplished  in a  non-public
                  offering in compliance with, and exempt from, the registration
                  and  qualification  requirements  of  all  federal  and  state
                  securities laws and regulations.

                           (ii) The Transfer  does not cause a default under any
                  material  contract to which the  Partnership  is a party or by
                  which the Partnership or any of its properties is bound.

                           (iii)  The   transferee   executes   an   appropriate
                  agreement to be bound by this Agreement.

                           (iv)  The  transferor  and/or  transferee  bears  all
                  reasonable  costs  incurred by the  Partnership  in connection
                  with the Transfer.

                           (v)  The   transferee   (or  the   guarantor  of  the
                  obligations  of the  transferee)  satisfies  the  criteria set
                  forth in Section 2.2(d) and delivers an agreement to the other
                  Parent and the Partnership  substantially  in the form of this
                  Agreement.

                           (vi) The proposed transferor is not in default in the
                  timely  performance of any of its material  obligations to the
                  Partnership.

                           (vii) The provisions of Section 2.2(f) are satisfied.

                  (f)  Neither  Parent may  Transfer  the  Partner  Sub Stock of
either of its  Partner  Subs to any Person  unless  such  Parent  simultaneously
Transfers  the  Partner  Sub Stock of its other  Partner Sub to such Person or a
wholly-owned Affiliate (as defined in the Partnership Agreement) of such Person.

         2.3  Prohibition  on Affiliated  Obligor  Bankruptcy,  Etc. Each Parent
hereby agrees that it will not, without the written consent of the other Parent,
permit any of its  Affiliated  Obligors (or their  successors or assigns) (i) to
commence  a  voluntary  action  under the  Federal  bankruptcy  laws,  as now or
hereafter  constituted,  or any other  applicable  Federal or State  bankruptcy,
insolvency  or  other  similar  law,  (ii)  to  institute  a  proceeding  to  be
adjudicated a voluntary bankrupt, (iii) to consent to the filing of a bankruptcy
proceeding  against it, (iv) to fail to contest a bankruptcy  proceeding against
it, (v) to consent to the  appointment of a receiver,  custodian,  liquidator or
trustee for it or for all or any  substantial  portion of its property,  (vi) in
the case of its Partner  Subs, to issue or sell other than to such Parent any of
its own Partner Sub Stock or (vii) to effect,  recognize  or permit any transfer
of any of its own Partner Sub Stock other than in accordance with the provisions
of Section 2 of this Agreement.

         2.4  Special  Purpose  Subsidiaries.  Each  Parent  agrees that (i) the
business of its Partner  Subs shall be  restricted  solely to the holding of the
respective  interests in the  Partnership  and the doing of things  necessary or
incidental in connection therewith,  and (ii) it will cause its Partner Subs not
to own any assets, incur any liabilities or engage, participate or invest in any
business  outside  the scope of their  businesses  as  described  in clause (i);
provided,  however,  that this  Section 2.4 shall not apply with  respect to any
Wholly  Owned  Affiliates  to  whom  such  Partner  Subs  shall  transfer  their
respective  interests in the Partnership if such Wholly Owned Affiliates are not
bound by Section 9.6 of the Partnership Agreement.


                                    SECTION 3
                              STANDSTILL AGREEMENT
                              --------------------

         3.1  Standstill.  Each Parent agrees that,  until the  expiration of 24
months from the date on which either such Parent and its Affiliates or the other
Parent and its Affiliates no longer hold an interest in the Partnership, neither
it, nor any of its Affiliated  Obligors or other  subsidiaries,  shall,  without
prior written approval of the other Parent: (i) in any manner acquire,  agree to
acquire or make any proposal to acquire, directly or indirectly, any securities,
assets or property of the other  Parent  (other than such  Parent's  Partner Sub
Stock or the interests in the Partnership  held by such Parent's  Partner Subs),
whether  such  agreement  or proposal  is made with or to the other  Parent or a
third  party;  (ii) make any  unsolicited  proposal to enter  into,  directly or
indirectly, any merger or other business combination involving the other Parent;
(iii)  make,  or  in  any  way  participate,  directly  or  indirectly,  in  any
"solicitation"  of  "proxies"  (as such terms are used in the proxy rules of the
Securities and Exchange  Commission) to vote, or seek to advise or influence any
person with respect to the voting of, any voting securities of the other Parent;
(iv) form,  join or in any way  participate in a "group"  (within the meaning of
Section  13(d)(3) of the  Securities  Exchange  Act of 1934) with respect to any
voting  securities of the other Parent;  (v) otherwise  act, alone or in concert
with others, to seek to control or influence the management,  Board of Directors
or  policies of the other  Parent  (other  than with  respect to the  ownership,
business, property and affairs of the Partnership); (vi) disclose any intention,
plan or arrangement inconsistent with the foregoing; or (vii) advise, encourage,
provide assistance  (including financial assistance) to or hold discussions with
any other  persons in  connection  with any of the  foregoing.  Each Parent also
agrees  during  such  period  not to:  (i)  request  the  other  Parent  (or its
directors,  officers,  employees or agents), directly or indirectly, to amend or
waive any provision of this Section 3.1 (including this sentence);  or (ii) take
any action  which might  reasonably  be expected to require the other  Parent to
make a public announcement  regarding the possibility of a business  combination
or merger.

         3.2      Exceptions.  Notwithstanding the provisions of Section 3.1:

         (a) Either Parent may, by notice to the other, terminate the provisions
of Section 3.1 (as applied to both Parents) at any time within 30 days after the
occurrence of any of the following events with respect to the other Parent:  (i)
a Change of Control (as defined below) of such other Parent shall have occurred,
(ii) such other Parent shall have entered into a definitive  agreement providing
for, or publicly announced its intention to effect, any transaction  involving a
Change of Control of such other Parent or (iii) a tender offer or exchange offer
shall have been commenced or publicly announced that, if consummated, would have
the effect  with  respect to such other  Parent  described  in clause (c) of the
definition  of "Change of Control." A "Change of Control" of a Parent shall mean
the  occurrence of any of the following  events:  (a) there shall be consummated
any  consolidation,  merger or share  exchange  of such Parent (i) in which such
Parent is not the  continuing or surviving  Person (other than a  consolidation,
merger or share exchange with a wholly owned  subsidiary of such Parent in which
all shares of common stock of such Parent  outstanding  immediately prior to the
effectiveness  thereof  are  changed  into or  exchanged  for the same number of
shares of common stock of such  subsidiary) or (ii) pursuant to which the common
stock of such Parent is converted into cash, securities or other property, other
than, in each case, a consolidation,  merger or share exchange of such Parent in
which the holders of the common stock  immediately  prior to the  consolidation,
merger or share  exchange hold,  directly or indirectly,  at least a majority of
the  voting  power and  common  equity of the  continuing  or  surviving  Person
immediately  after  such  consolidation,  merger  or  share  exchange;  (b) such
Parent's  properties and assets are sold or otherwise  disposed of substantially
as an entirety on a consolidated  basis to any Person or group of Persons in any
one transaction or a series of related transactions,  other than as contemplated
by the Master  Transaction  Agreement;  or (c) any Person or any Persons  acting
together  which would  constitute  a "group" (as defined in Section  3.1) (other
than such Parent,  any  subsidiary of such Parent,  any employee  stock purchase
plan,  stock option plan or other stock  incentive  plan or program,  retirement
plan or automatic dividend  reinvestment plan or any substantially  similar plan
of such Parent or any subsidiary of such Parent or any Person holding securities
of such Parent for or pursuant to the terms of any such employee  benefit plan),
together with any affiliates  thereof,  shall acquire  beneficial  ownership (as
defined in Rule 13d-3 under the Securities  Exchange Act of 1934) of 50% or more
of the voting stock of such Parent.

         (b) The  terms of the  first  sentence  of  Section  3.1  shall  not be
applicable  to the  purchase and sale of any  securities  of the other Parent by
independent  third-party  managers  of any  pension  or other  related  employee
benefit plans who are acting as passive investors in the other Parent.


                                    SECTION 4
                                  MISCELLANEOUS
                                  -------------

         4.1 No  Waivers.  No failure or delay by a  Beneficiary  or a Parent in
exercising  any right or power  under this  Agreement,  or any single or partial
exercise  of any such  right or  power,  shall  preclude  any  other or  further
exercise  thereof or the  exercise of any other  right or power.  Such single or
partial  exercise of any right or power shall be cumulative and not exclusive of
any rights or remedies provided by law.

         4.2 Expenses in  Connection  with  Exercise.  In the event of a dispute
between  parties  hereto  regarding  the exercise or  enforcement  of any of the
rights of a  Beneficiary  under  this  Agreement  or the  failure by a Parent to
perform or observe any of the provisions of this Agreement,  the party that does
not ultimately  prevail in such dispute shall be liable,  and hereby agrees,  to
reimburse,  on demand, each other such party for any and all costs and expenses,
including  the fees and  expenses  of legal  counsel  and of any other  counsel,
experts,  consultants  or agents,  that such other party may incur in connection
therewith.

         4.3  Subordination.  The  rights  of a Parent  against  its  Affiliated
Obligors  arising from any payment or performance by a Parent hereunder shall be
subordinate  in all  respects to the rights of the  Beneficiaries  against  such
Affiliated  Obligors,  and  such  Parent  shall  not  compete  in any way with a
Beneficiary in any winding-up or dissolution of such Affiliated  Obligors unless
and until all sums due and to become due from such  Affiliated  Obligors  to the
Beneficiaries have been paid in full. If any amount shall be paid to a Parent in
violation of this Section, such amount shall be held in trust for the benefit of
the  Beneficiaries  and  shall  forthwith  be  paid to the  Beneficiaries  to be
credited and applied to any sums owed or to be owed by such Parent's  Affiliated
Obligors.  Subject to the  foregoing,  upon payment of all sums due or to become
due by Affiliated  Obligors to the Beneficiaries,  the Parent of such Affiliated
Obligors  shall be  subrogated  to the rights of the  Beneficiary  against  such
Affiliated  Obligors,  and the  Beneficiaries  agree  to  take at such  Parent's
expense  such steps as such  Parent may  reasonably  request to  implement  such
subrogation.

         4.4 Confidentiality  and Use of Information.  (a) Each Parent agrees to
be  bound  by the  terms  and  conditions  of  Section  13.1 of the  Partnership
Agreement as if such Parent was a "Partner" as defined in such agreement.

         (b) The Parents  shall consult with each other on an ongoing basis with
respect to disclosures  regarding the  Partnership  and its business and affairs
that  each is  required  to make in  reports  filed  from  time to time with the
Securities and Exchange Commission.

         4.5  Competing  Businesses.  If either  Parent  desires to  initiate or
pursue any opportunity to undertake,  engage in, acquire or invest in a Business
Opportunity (as such term is defined in the Partnership Agreement),  such Parent
agrees to offer such Business Opportunity to the Partnership under the terms and
conditions set forth in Sections 9.3(c) and (d) of the Partnership  Agreement as
if such  Parent were the  "Proposing  Partner"  (as  defined in the  Partnership
Agreement) with respect  thereto,  and in such event the Partnership  shall have
the rights and  obligations  with  respect  thereto  set forth in such  Sections
9.3(c) and (d).

         4.6  Further  Assurances.  From  time to time,  each  Parent  agrees to
execute and deliver  such  additional  documents  and  provide  such  additional
information and assistance as the Beneficiaries may reasonably  require to carry
out the terms of this Agreement.

         4.7 Successors and Assigns. Except as may be expressly provided herein,
this Agreement  shall be binding upon and inure to the benefit of the successors
of the  Beneficiaries.  Except as provided in this  Agreement  and except that a
Parent  may assign its rights or  obligations  under this  Agreement  to a third
party in connection with a transfer of direct interests in the Partnership owned
by its Partner Subs if such transfer is permitted and  consummated in accordance
with the  Partnership  Agreement,  no Parent may assign or  delegate  any of its
rights or obligations  under this Agreement without the prior written consent of
all  the  Beneficiaries,  which  consent  shall  be in  the  sole  and  absolute
discretion of such Beneficiaries. Any purported assignment or delegation without
such consent shall be void and ineffective.

         4.8 Benefits of Agreement Restricted to the Parties.  This Agreement is
made solely for the benefit of the  Beneficiaries  (as defined in Section 1.11),
and no other Person  shall have any right,  claim or cause of action under or by
virtue of this Agreement.

         4.9 Notices.  All notices,  requests,  demands and other communications
(collectively, "notices") required or may be given under this Agreement shall be
in  writing  and  shall  be  deemed  to have  been  duly  given  if and when (i)
transmitted  by  telecopier  facsimile  with  proof  of  confirmation  from  the
transmitting  machine  or (ii)  delivered  by  commercial  courier or other hand
delivery, as follows:

                          DISPUTE RESOLUTION PROCEDURES
                          -----------------------------


         (1) Binding and Exclusive Means. The dispute resolution  provisions set
forth in this Appendix B shall be the binding and exclusive means to resolve all
disputes arising under this Agreement (each a "Dispute").

         (2) Standards and Criteria. In resolving any Dispute, the standards and
criteria  for  resolving  such  dispute  shall,  unless  the  Parents  in  their
discretion  jointly stipulate  otherwise,  be as set forth in Appendix 1 to this
Appendix B.

         (3) ADR and Binding  Arbitration  Procedures.  If a Dispute arises, the
following procedures shall be implemented:

         (a) The Parent from whom  recovery is sought may at any time invoke the
dispute resolution  procedures set forth in this Appendix B as to any Dispute by
providing  written  notice of such action to the other  Parent,  who within five
Business Days after such notice shall  schedule a meeting to be held in Houston,
Texas between the Parents. The meeting shall occur within 10 Business Days after
notice of the meeting is delivered  to the other  Parent.  The meeting  shall be
attended by  representatives  of each Parent  having  decision-making  authority
regarding  the Dispute as well as the dispute  resolution  process and who shall
attempt in a  commercially  reasonable  manner to negotiate a resolution  of the
Dispute.

         (b)  The   representatives   of  the  Parents  shall   cooperate  in  a
commercially  reasonable  manner and shall explore  whether  techniques  such as
mediation,  minitrials,  mock trials or other techniques of alternative  dispute
resolution might be useful. In the event that a technique of alternative dispute
resolution is so agreed upon, a specific  timetable and completion  date for its
implementation  shall also be agreed upon. The representatives  will continue to
meet and discuss settlement until the date (the "Interim Decision Date") that is
the earliest to occur of the following events: (i) an agreement shall be reached
by the Parents  resolving the Dispute;  (ii) one of the Parents shall  determine
and notify the other Parent in writing that no agreement  resolving  the Dispute
is likely to be reached;  (iii) if a technique of alternative dispute resolution
is agreed upon,  the  completion  date therefor  shall occur without the Parents
having resolved the Dispute; or (iv) if another technique of alternative dispute
resolution is not agreed upon,  two full meeting days (or such other time period
as may be agreed  upon) shall  expire  without the Parents  having  resolved the
Dispute.

         (c) If, as of the Interim Decision Date, the Parents have not succeeded
in  negotiating  a resolution  of the dispute  pursuant to  subsection  (b), the
Parents shall proceed under subsection (d).

         (d) The Parents agree to appoint a mutually  acceptable  neutral person
not affiliated with any of the Parents (the "Neutral"). If the Parents have been
unable to agree upon such appointment  within 30 days after the Interim Decision
Date, then such Neutral,  upon the application of either of the Parents shall be
appointed  within 10 days of the  filing of such  application  by the Center for
Public  Resources,  or if such appointment is not so made promptly then promptly
thereafter   by  the   American   Arbitration   Association   in   Philadelphia,
Pennsylvania,  or if such  appointment  is not so made  promptly  then  promptly
thereafter  by  the  senior  United  States  District  Court  judge  sitting  in
Wilmington,  Delaware.  The fees of the  Neutral  shall be paid  equally  by the
Parents except that the Neutral shall have discretion to award fees.

         (e) In  consultation  with the Neutral,  the Parents shall agree upon a
binding  schedule  and  procedure  (which  procedure  may have  been  previously
discussed  under  subsection (b)) to be used as a means to resolve or to attempt
to resolve  Dispute,  with the Neutral  making the  decision as to the  schedule
and/or procedure if the Parents have been unable to agree on any of such matters
within 20 days after the initial selection of the Neutral.  The Parents agree to
participate  in a  commercially  reasonable  manner  in  the  procedure  to  its
conclusion as determined  by the Neutral.  If the Parents are not  successful in
resolving the Dispute through the procedure  described  above,  then the Parents
agree that (i) the Neutral shall act as the arbitrator in a binding  arbitration
in accordance with the American Arbitration Association rules and shall render a
decision  and (ii)  judgment  upon the  decision  rendered by the Neutral may be
entered in any court having jurisdiction.

         (4)  Continuation  of Business.  Notwithstanding  the  existence of any
Dispute or the  pendency  of any  procedures  pursuant  to this  Appendix B, the
Parents agree and undertake  that all payments not in dispute shall  continue to
be made and all obligations not in dispute shall continue to be performed.

                                   ----------


         (a) First priority shall be given to maximizing the  consistency of the
resolution of the Dispute with the  satisfaction  of all express  obligations of
the Parents and their Affiliates as set forth in the Agreement.

         (b) Second  priority  shall be given to  resolution of the Dispute in a
manner  which best  achieves  the  objectives  of the  business  activities  and
arrangements under the Agreement and permits the Parents to realize the benefits
intended to be afforded thereby.

         (c) Third priority shall be given to such other matters, if any, as the
Parents  or  the  Neutral   shall   determine  to  be   appropriate   under  the
circumstances.

year end."
