include the employee's time of service with a Contributor, its predecessors or
Affiliates (to the extent service therefor would have been credited by a
Contributor) and the Partnership).

         (d)     Any employees of a Contributor that the Partnership and such
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 such Contributor on terms and
conditions and for a duration to be agreed upon by the Partnership and such
Contributor.  The Partnership shall reimburse such Contributor for any such
agreed upon compensation, including payroll taxes, benefit costs  and workers
compensation premiums and claims, paid by such Contributor to or with respect
to any Transition Employee.

         (e)     If, as of the Expiration Date, any Employee is eligible for
and receiving short term disability benefits or sick pay, or is on leave of
absence, 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 such Contributor under the applicable
conditions of the short term disability benefits or sick pay plan of the
Contributor, or upon return from leave of absence.  Partnership employment
shall not be effective until the employing 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 such
Contributor shall continue to bear all costs and expenses associated with such
Employee.

         (f)     None of the Contributors nor any of their Affiliates shall, at
any time prior to 60 days after the Expiration 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 Contributors or
any of their Affiliates without complying fully with the notice and all other
applicable requirements of WARN.  With regard to the Contributed Business, the
Partnership shall not at any time prior to 60 days after the Expiration Date,
effectuate a "plant closing" or a "mass layoff", as those terms are defined in
WARN, affecting in whole or in part, any facility, site of employment or
operating unit, or any Employees without complying fully with the notice and
all other applicable requirements of that Act.

         (g)     In connection with the provision by the Partnership of benefit
plans and programs for Partnership Employees as provided in the Master
Transaction Agreement,





                                     - 12 -
   18
                 (i)      The Partnership shall recognize all service credited
         for the Partnership Employees or any other employee of Contributors or
         their Affiliates directly transferred to the Partnership after the
         Expiration Date on the records of a Contributor (or its Affiliate) for
         purposes of eligibility for benefits and vesting under the
         Partnership's benefit plans and programs and calculation of benefits
         under the Partnership's benefit plans and programs, other than the
         Partnership's defined benefit pension plan.  For purposes of this
         Section 2.8(g)(i), an employee shall be directly transferred if the
         person is employed by the Contributors or their Affiliates immediately
         prior to his or her employment with the Partnership and if such
         employment with the Partnership is the result of an agreement between
         the Partnership and the Contributors or their Affiliates.  The
         Partnership shall not recognize service credited on a Contributor's
         records for benefit accrual under the Partnership's defined benefit
         pension plan and only actual periods of service with the Partnership
         shall be credited for such benefit accrual purposes;

                 (ii)     As of the Expiration Date, to the extent a
         Contributor (or its Affiliate) is not otherwise required to vest
         Partnership Employees as plan participants, the Contributors shall
         cause each Partnership Employee to become fully vested in his
         interests in the Occidental Petroleum Corporation Savings Plan (the
         "PSA"), the Occidental Chemical Corporation Savings and Investment
         Plan (the "SIP") and the Occidental Petroleum Corporation Retirement
         Plan (the "PRA") (hereinafter collectively referred to as
         "Occidental's Qualified Plans");

                 (iii)    As of the Expiration Date, the Partnership shall
         provide each Partnership Employee who was not covered by a collective
         bargaining agreement immediately prior to the Closing Date (a
         "Non-Union Employee") with "Partnership Benefit Plans", which shall
         mean the benefit plans and programs under (a) all employee plans
         applicable to employees of the Partnership in similar jobs, other than
         any employee plan that provides benefits under section 401(k) of the
         Code ("Partnership 401(k) Plan"), and (b) a plan sponsored by the
         Partnership that is substantially identical to the PSA (the "Mirror
         Plan"); provided, however that the Mirror Plan will (w) provide for a
         level of matching contributions and forms of distribution identical to
         that provided by the Partnership 401(k) Plan (except as required by
         law for benefits transferred from the PSA and SIP), (x) not offer
         investment in guaranteed investment contracts, (y) not offer new
         investments in Occidental common stock and (z) not offer investments
         in Occidental common stock after September 30, 1998.  From and after
         the Expiration Date, each Non-Union Employee shall be eligible to
         participate in such Partnership Benefit Plans in accordance with the
         terms and conditions thereof; provided, however, that from and after
         January 1, 1999 such Non-Union Employee shall commence participation
         in the Partnership 401(k) Plan and shall no longer be entitled to
         contributions under the Mirror Plan.  Under such Partnership Benefit
         Plans which are Employee Welfare Benefit Plans, Non-Union Employees
         and their eligible dependents, if a participant in any health, long
         term disability or life insurance plans, as applicable, of a
         Contributor or its Affiliates immediately prior to the Expiration
         Date, (a) shall participate in such Partnership Benefit Plans as of
         the Expiration Date, and (b) shall be deemed to satisfy any
         pre-existing condition limitations under group medical, dental, life
         insurance or disability plans that shall be provided after the





                                     - 13 -
   19
         Expiration Date.  In addition, subject to the agreement of the
         third-party administrator, amounts paid by such Non-Union Employees
         towards deductibles and co-payment limitations under the health plans
         of a Contributor or its Affiliates shall be counted toward meeting any
         similar deductible and copayment limitations under the health plans
         that shall be provided under the Partnership Benefit Plans.

                 (iv)     The Contributors shall, or shall cause its
         Affiliates, as appropriate to, and the Partnership shall take all
         necessary and reasonable steps to prevent a loan default under the PSA
         and the SIP (collectively the "Contributors' 401(k) Plans"), including
         the following:  (a) the Contributors shall, or shall cause its
         Affiliates, as appropriate, to allow Partnership Employees to repay
         their loans under the Contributors' 401(k) Plans during any period
         during which the Contributors or its Affiliates provide payroll
         services, and (b) the Contributors shall cause Occidental to agree and
         the Partnership agrees to take the necessary and reasonable steps to
         provide for a plan to plan transfer (as such transfer is defined in
         Section 414(l) of the Code) of account balances (including outstanding
         loans) of Partnership Employees from the Contributor's 401(k) Plans to
         the appropriate Partnership's 401(k) Plan.  Notwithstanding the
         foregoing, any steps which in the sole discretion of the Contributors
         or its Affiliates jeopardizes the tax- qualified status of any of its
         Employee Plans shall be deemed unreasonable.

                 (v)      From and after the Expiration Date, Non-Union
         Employees shall be entitled to retain and take any paid vacation days
         accrued but not taken under a Contributor's vacation policy for the
         period from January 1, 1998 through the Expiration Date.  Upon or
         promptly after the Expiration Date, the Contributor shall pay any
         Banked Vacation and Carryover Vacation.  "Banked Vacation" shall mean
         vacation time accrued on the Contributor's records as payable to any
         Partnership Employee who is a Non-Union Employee for which vacation
         time has not been taken for the period prior to January 1, 1982, 1986
         or 1988, as appropriate for such Partnership Employee.  "Carryover
         Vacation" shall mean vacation time which (a) is not Banked Vacation;
         (b) has been accrued on the Contributor's records as payable and
         approved by designated personnel for any Partnership Employee who is a
         Non-Union Employee; and (c) such vacation time has not been taken
         prior to the Expiration Date and which was earned for any period prior
         to January 1, 1998.

         (h)     Subject to the representations in Section 3.4 hereof, as soon
as possible after the Expiration Date the Contributor and the Partnership shall
take all actions necessary to cause (i) the Contributor to cease to be the plan
sponsor of the Cain Pension Plan ("Cain Plan") and the PDG Chemical Inc.
Pension Plan ("PDG Plan"), (ii) the Partnership to become the plan sponsor of
the Cain Plan and the PDG Plan and to assume all present and future obligations
and liabilities of the Contributor with respect to such plan, and (iii) the
Partnership shall recognize service with Occidental or its Affiliates for early
retirement eligibility purposes under the Cain Plan and the PDG Plan.  From and
after the Expiration Date until the instruction to liquidate assets from the
Contributor's master trust for the purpose of transferring assets to the
Partnership's trust, assets relating to the Cain Plan and the PDG Plan shall be
invested at the discretion of the fiduciaries of such plans, in the normal
course, subject to all applicable laws and plan and trust provisions.  Any
earnings or losses on such





                                     - 14 -
   20
assets after the Expiration Date shall be based on the return of the
Contributor's trust as determined by the Contributor's trustee.  After
liquidation of assets until the date of transfer of the assets of the Cain Plan
and PDG Plan, earnings or losses on such assets shall be based on the Short
Term Investment Fund ("STIF") rate of The Northern Trust Company, the trustee
of  such plans.

         (i)     As of the Expiration Date, the Partnership Employees shall
cease to accrue service credit, except as expressly provided in this Section
2.8, under any and all of the Employee Welfare Benefit Plans of the
Contributors or its Affiliates, under any and all of the Employee Pension
Benefit Plans of the Contributor or its Affiliates, and any and all non-ERISA
plans or programs of the Contributor or its Affiliates, in which participation
had been available to such Employees prior to the Expiration Date.  The
Contributors agree that, with respect to any Partnership Employee directly
transferred from the Partnership to employment with the Contributors or their
Affiliates, they will recognize all service credited for such Partnership
Employee on the records of the Partnership for purposes of eligibility for
benefits and vesting under the benefit plans and programs of the Contributors
and their Affiliates and calculation of benefits under the benefit plans and
programs of the Contributors and their Affiliates, other than the defined
benefit pension plan of the Contributors and their Affiliates.  For purposes of
this Section 2.8(i), an employee shall be directly transferred if the person is
employed by the Partnership immediately prior to his or her employment with the
Contributors or their Affiliates and if such employment with the Contributors
or their Affiliates is the result of an agreement between the Partnership and
the Contributors or their Affiliates.

         (j)     The Contributors or their Affiliates shall retain the sole
responsibility for, and shall continue to pay, all hospital, medical, and
health care continuation coverage benefits as described in section 4980B of the
Code, life insurance, disability, other welfare plan expenses and benefits
(including all benefits under the Employee Plans), and worker's compensation
for employees of the Contributors (including each Employee) and their covered
dependents, including "qualified beneficiaries" within the meaning of section
607(3) of ERISA, with respect to claims incurred prior to the Expiration Date.
In addition, the Contributors or their Affiliates shall retain sole
responsibility for the payment of any claim for medical benefits, health care
continuation coverage benefits as described in section 4980B of the Code, life
insurance or other welfare benefits by, or any other item of compensation or
benefits payable under any Contributor Employee Welfare Benefit Plan to (i) any
employee of the Contributor on and after the Expiration Date, (ii) any former
employee of the Contributor who retired, died, became long-term disabled or
otherwise terminated employment prior to the Expiration Date, and (iii) any
"qualified beneficiary" of a Partnership Employee with respect to whom a
"qualifying event" (as such terms are defined in sections 603 and 607 of ERISA)
has occurred prior to the Expiration Date.  Except as set forth above, expenses
and benefits relating to such types of claims incurred by Partnership Employees
and their covered dependents on or after the Expiration Date shall be the sole
responsibility of the Partnership to the extent covered under the terms of its
benefit plans.  For the purposes of this Section 2.8(j), a claim is deemed
incurred when the services giving rise to the claim were performed.

         (k)     The Contributors and the Partnership agree that they will
satisfy their respective obligations, if any, under the National Labor
Relations Act regarding union represented employees of the Contributor at the
Beaumont, Texas, PD Glycol Plant.  Further, the Partnership will recognize





                                     - 15 -
   21
the Oil, Chemical and Atomic Workers International Union and its Local No.
4-243, Production and Maintenance Group, at the Beaumont, Texas, PD Glycol
Plant.

         (l)     Except as otherwise specified in this Section 2.8, in the
event that a Contributor or its Affiliates terminates any of its employees
other than the Employees at any time prior to the Expiration Date, the
Contributor shall be solely responsible for any liability with respect to such
termination, including liability for all severance benefit payments to such
employees pursuant to its severance plan and any costs associated with
violation of any applicable Authority.  Notwithstanding the foregoing, the
Partnership hereby agrees to indemnify the Contributors and their Affiliates
and to defend and hold the Contributors and their Affiliates harmless from and
against any claims, losses, expenses, obligations, and liabilities (including
cost of defense and reasonable attorney's fees) asserted against and imposed on
the Contributors and their Affiliates and arising out of or otherwise in
respect of the following:  (i) the Partnership's termination of any Partnership
Employee's employment with the Partnership; (ii) any failure by the Partnership
to comply with its obligations hereunder or otherwise with respect to any
Partnership Employee; (iii) any suit or claim of violation brought against the
Contributors or their Affiliates under WARN for any actions taken by the
Partnership after the Expiration Date with regard to the Partnership Employees
at any facility, site of employment or operating unit affected by this
Agreement; or (iv) all claims by any Partnership Employee after the Expiration
Date whom the Partnership or its Affiliates actually or constructively
terminates or by any spouse, dependent, estate or other beneficiary of such
Employee, and (v) from any claims or charges by or relating to Employee
concerning wrongful termination, discrimination, harassment, or violation of
(a) the Fair Labor Standards Act, (b) the Labor Management Relations Act, (c)
WARN, (d) the Americans With Disabilities Act, (e) ERISA, (f) the Consolidated
Omnibus Budget Reconciliation Act of 1985, (g) the National Labor Relations
Act, (h) the Family and Medical Leave Act, (i) the Health Insurance Portability
and Accountability Act, (j) Title VII of the Civil Rights Act of 1964, (k) the
Age Discrimination in Employment Act, or (l) any and all applicable state and
local laws relating to employees or labor relations, all as attributable to the
conduct of the Partnership or its Affiliates with respect to such Employee
relating to the period subsequent to the Expiration Date.  The Partnership
hereby agrees to indemnify the Contributors and their Affiliates and to defend
and hold Contributors and their Affiliates harmless from and against fifty
percent of any claims, losses, expenses, obligations and liabilities (including
cost of defense and reasonable attorney's fees) asserted against and imposed on
the Contributors and their Affiliates and arising out of the Partnership's and
Contributor's joint selection of the Employees offered employment by the
Partnership.

         (m)     Nothing expressed or implied in this Agreement shall confer
upon any Employee, or any legal representative thereof, any rights or remedies,
including any right to employment, whether directly or as a third party
beneficiary, or continued employment for any specified period, of any nature or
kind whatsoever.

         (n)     Except as otherwise specified in this Section 2.8, the
Contributors agree to indemnify the Partnership and to defend and hold the
Partnership and its Affiliates harmless from and against claims, losses,
expenses, obligations, and liabilities (including costs of defense and
reasonable attorney's fees) arising out of or otherwise in respect of the
following (i) any Contributor employee





                                     - 16 -

benefit plans, or claims of employees or former employees of the Contributor or
of any spouse, dependent, estate, or other beneficiary of such employees or
former employees that in any case arose prior to the Expiration Date,
including, without limitation, any such liability or obligation which may arise
under Section 2.8(j) and from (ii) any claims or charges relating to wrongful
termination, discrimination, harassment, or violation of (a) the Fair Labor
Standards Act, (b) the Labor Management Relations Act, (c) WARN, (d) the
Americans With Disabilities Act, (e) ERISA, (f) the Consolidated Omnibus Budget
Reconciliation Act of 1985, (g) the National Labor Relations Act, (h) the
Family and Medical Leave Act, (i) the Health Insurance Portability and
Accountability Act, (j) Title VII of the Civil Rights Act of 1964, (k) the Age
Discrimination in Employment Act, or (l) any and all applicable state and local
laws relating to employees or labor relations, all as attributable to the
conduct of the Contributor or its Affiliates with respect to (A) any employees
or former employees of the Contributor who do not become Partnership Employees
relating to the periods both before and after the Expiration Date, and (B) the
Employees, relating to the period prior to the Expiration Date.

         (o)     Representatives of the Partnership shall be entitled to meet
with the Employees at mutually agreeable times prior to the Expiration Date to
explain and answer questions about the conditions, policies and benefits of
employment by Partnership after the Expiration Date.  The Contributors shall
cooperate with the Partnership until Expiration Date in communicating to such
Employees any additional information concerning employment after the Expiration
Date which such Employees may seek, or which the Partnership may desire to
provide, and during normal business hours shall allow additional meetings by
representatives of the Partnership with such Employees upon the reasonable
request of the Partnership.  In addition, the Contributor and the Partnership
agree to furnish each other with appropriate records for each of the Employees
as may be necessary to assist in proper benefit administration.

         (p)     The indemnity provisions of this Section shall be subject to
the requirements of Section 6.3 of this Agreement.

         2.9     Joint Contracts.

         (a)     Any Contributed Contracts contributed to the Partnership
pursuant to  Section 1.2 or 2.1 that relate principally to the Contributed
Business but also relate to the business (other than the Contributed Business)
of an Asset Contributor or its Affiliates will be made available to the
appropriate Asset Contributor and its Affiliates by the Partnership pursuant to
arrangements by which such Asset 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 an Asset Contributor or its Affiliates but
also relate to the Contributed Business will be made available to the

               REPRESENTATIONS AND WARRANTIES OF THE CONTRIBUTORS

         Except as set forth on Schedule 3 or in the SEC Reports, each
Contributor and Oxy CH Sub represent and warrant to the Partnership as follows:

         3.1     Due Organization; Good Standing and Power.  Each Contributor
and Oxy CH Sub are corporations duly organized, validly existing and in good
standing under the laws of its state of organization and each Contributor has
the requisite 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.  Each Contributor and Oxy CH Sub has all requisite power and
authority to enter into this Agreement and the Assignment and Assumption
Agreements and to perform its obligations hereunder and thereunder.  Each
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
each Contributor and Oxy CH Sub and the consummation by it of the transactions
contemplated hereby and thereby have been duly authorized by the Board of
Directors of such Person.  Except to the extent heretofore obtained, no other
corporate action or action by stockholders is necessary for the authorization,
execution, delivery and performance by a Contributor and Oxy CH Sub of this
Agreement and the other Related Agreements and the consummation by any such
Person of the transactions contemplated hereby or thereby.  This Agreement and
the other Related Agreements have been duly executed and delivered by each
Contributor and Oxy CH Sub and constitute legal, valid and binding obligations
of such Person, 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 a
Contributor is a Party.  The execution, delivery and performance of this
Agreement and the other Related Agreements by the Contributors, Oxy CH Sub and
any of their Affiliates that is a party thereto and the consummation by each
such Person 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 such
Person, 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
such Person, or any indenture, mortgage, deed of trust, lease, licensing
agreement, contract, instrument or other agreement to which such Person is a
party or by which such Person or





                                     - 18 -
   24
any of the Assets held by such Person 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)     Each 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.  No Contributor has received any 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, no
         Contributor has  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)     No Contributor has 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 each 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 302 of ERISA).

         (b)     Each 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.





                                     - 19 -
   25
         (c)     There has been no act or omission by a 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)     Each Contributor has good and marketable title to all of its
Fee Interests, free and clear of all Encumbrances, except (i) any prior
reservations, easements and other matters of record to the extent valid,
subsisting and affecting the Assets, (ii) any prior unrecorded easements for
which improvements have been constructed in such a manner as to be apparent to
the Partnership from inspection of the Assets to the extent valid, subsisting
and affecting the Assets, (iii) liens for current taxes not yet due and payable
and mechanics and similar statutory liens arising in the ordinary course of
business, (iv) liens of employees and laborers for current wages not yet due,
(v) building, zoning and health regulations of the jurisdictions in which the
Assets are located; and (vi) 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)     Each Contributor is the sole lessee under its Leases and the
sole party entitled to its Leasehold interests in favor of the lessee
thereunder, and the sole owner or, in the case of OCC Sub, the sole lessee, of
the improvements (other than fixtures) situated on its Leased Premises, free and
clear of all Encumbrances affecting its Leaseholds except (i) any prior
reservations, easements and other matters of record to the extent valid,
subsisting and affecting the Assets, (ii) any prior unrecorded easements for
which improvements have been constructed in such a manner as to be apparent to
the Partnership from inspection of the Assets to the extent valid, subsisting
and affecting the Assets, (iii) liens for current taxes not yet due and payable
and mechanics and similar statutory liens arising in the ordinary course of
business, (iv) liens of employees and laborers for current wages not yet due,
(v) building, zoning and health regulations of the jurisdictions in which the
Assets are located; and (vi) such imperfections of title, easements and 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.  No Contributor or
any Affiliate thereof has received from or delivered to the lessors under such
Leaseholds any written notice of termination or threat of termination of such
respective Leaseholds.  True and complete copies of all written lease agreements
(including any written amendments or modifications thereof) constituting, or
evidencing the terms of, such Leaseholds have been delivered or made available
to the Partnership.  No material default or event of default on the part of a
Contributor or any Affiliate thereof 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 such
Contributor, has occurred (which default or event of default has not been
cured).  No Contributor or 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 such 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 




                                     - 20 -
   26
of such 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)     Each Contributor or an Affiliate thereof has good title to all
of the personal property constituting Assets 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 of a Contributor or any Affiliate thereof
that would reasonably be expected to have a Material Adverse Effect.  No
Contributor or 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 its Fee
Interests or the Leased Premises.  No written notice has been received by a
Contributor or any Affiliate thereof from any insurance company with respect to
its 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.  Each Contributor has operated the
Contributed Business in the ordinary course of business from September 30, 1997
to the Closing Date such that its Inventory, Stores Inventory, Prepaid
Expenses, Accounts Receivable (and all reserves or allowances for doubtful
accounts, returned products or potential price adjustments) and Trade Accounts
Payable, as of the Closing Date, are at substantially the same level as would
have existed for such Contributor without regard to the transactions
contemplated by the Master Transaction Agreement.  In connection with this
Section 3.7, it is understood among the parties that the Originator Receivables
Sale Agreement dated as of October 29, 1998, by and among Occidental
Receivables Inc., OCC and other parties, has been terminated with respect to
Oxy Petrochemicals.

         3.8     Technology and Similar Rights.  Each Contributor owns or is
licensed to use all of its Intellectual Property, Licensed Technology and
Licensed Trademarks, and such Intellectual Property, Licensed Technology and
Licensed Trademarks together with the rights assigned or licensed under the
Related Agreements 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.

   27
         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.  Each 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 a Contributor or
any Affiliate thereof is a party (i) that is pending or, to the Knowledge of a
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 a
Contributor or any of its Affiliates, could reasonably be expected to have a
Material Adverse Effect.

         3.13    [Reserved].

         3.14    Tax Matters.

         (a)     There are no material liens for Taxes (other than for current
Taxes not yet due and payable) upon the Assets.

         (b)     None of the Assets directly or indirectly secures any
indebtedness for money borrowed the interest on which is tax-exempt.

         3.15    [Reserved].

         3.16    HSE Matters.  Except as would not be reasonably likely to have
a Material Adverse Effect:

         (a)     (i)      The Fee Interests, the Leased Premises and the
operations of each Contributor and any Affiliate thereof in connection with the
Contributed Business are in compliance with all HSE Laws and (ii) to the extent
arising out of a Contributor's or any Affiliate's ownership or use of the
Assets or operation of the Contributed Business, there are no Chemical

                                     - 22 -
   28
released, generated, treated, stored or disposed of, on, under or from such Fee
Interests or such Leased Premises or in, on or from any fixtures or improvement
thereon in excess of any standard prescribed or permitted by any HSE Laws or
which require corrective or other action pursuant to the provisions of any HSE
Laws.

         (b)     No Contributor or any Affiliate has received any notice from
any federal, state, or local agency naming such Contributor or such Affiliate
as a potentially responsible party ("PRP"), or otherwise notifying such
Contributor or such Affiliate of any potential liability under either the
Comprehensive Environmental Response, Compensation and Liability Act of 1980,
as amended ("CERCLA" or "Superfund"), the Resource Conservation and Recovery
Act of 1976, as amended ("RCRA"), or any state statute, rule or local
regulation imposing liability similar to CERCLA or RCRA that relates in any way
to any Chemical Substances generated by or derived from the operations on the
Fee Interests, or the Leased Premises of such Contributor or any Affiliate; nor
has either  Contributor or any of its Affiliates received any comparable claim
or notice from any private party.

         (c)     Each Contributor or an Affiliate thereof, as applicable, has
been and is, in compliance with, all permits, licenses, approvals, permission,
or authorizations necessary for its operations in connection with the
Contributed Business to comply in all respects with HSE Laws.

         (d)     (i) No Contributor or any Affiliate thereof has received
written notice of any actual, impending, or potential proceedings, allegations,
claims, losses, actions, investigations or inquiries of any kind in connection
with the Contributed Business and HSE Laws or Chemical Substances ("HSE
Proceedings") and (ii) no Contributor nor any Affiliate thereof has any
Knowledge of any facts, events or occurrences that would reasonably be expected
to result in any HSE Proceedings being brought.

subject to the terms of, any consent order, consent judgment, consent decree,
court or administrative order or judgment, agreement, schedule, or decree
issued by any Authority with respect to the Contributed Business.

         3.17    Investigation to Acquire Knowledge.  Each of the persons
covered by clauses (i) and (ii) of the definition of "Knowledge" set forth in
Section 1 has reviewed, with counsel to such Contributor, the other
representations and warranties contained in, and the Schedules that relate to,
this Section 3 to the extent that they relate to such person's area of
responsibility or expertise and has made a reasonable inquiry as to the
accuracy and completeness of such representations, warranties and Schedules.

               REPRESENTATIONS AND WARRANTIES OF THE PARTNERSHIP

         The Partnership represents and warrants to each 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





                                     - 24 -
   30
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 Asset
Contributors, Oxy CH Sub, their 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 an Asset Contributor or Oxy CH
Sub to facilitate (i) the preparation by such Asset Contributor or Oxy CH Sub
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 such Asset Contributor or Oxy CH Sub 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 such
Asset Contributor or Oxy CH Sub to permit it, at its expense, to examine,
duplicate or repossess such records, files, documents and correspondence.

         5.2     Mail or Other Communications.  Each Asset Contributor or Oxy
CH Sub 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.  Each Asset Contributor and Oxy CH Sub
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 appropriate Asset Contributor or Oxy CH Sub 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 Trade Name.  Pursuant to the Trademark License to be
granted to the Partnership by Occidental and OCC, 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 materials that bear the names set forth on Schedule 2.2(c) or
other trademarks or trade names of which such names or any name similar thereto
forms a part.

         5.4     Closing Date Balance Sheet.  Not later than 60 days after the
Closing Date, each Contributor shall cause Arthur Andersen LLP to prepare and
deliver to such Contributor and the Partnership an audited balance sheet of the
Contributed Business as of the Closing Date (the "Closing Date Balance Sheet").
In addition, each Contributor shall prepare and deliver to the Partnership such
other financial statements or information as the Partnership may reasonably
request in connection with any proposed Partnership financing; it is currently
anticipated that the Partnership will request the Contributors to provide the
Partnership with audited financial statements related to the operation of the
Contributed Business  for the past three (3) fiscal years.

         5.5     [Reserved]

         5.6     Collection of Accounts Receivable.  The Partnership shall take
all commercially reasonable efforts to collect any Accounts Receivable;
provided, 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 appropriate Contributor (or, in the case of Oxy
Petrochemicals, Oxy CH Sub) will buy such uncollected Accounts Receivable from
the Partnership at the amount set forth on the Closing Date Balance Sheet;
provided, further, that the amount to be paid by the appropriate Contributor
(or, in the case of Oxy Petrochemicals, Oxy CH Sub) for such uncollected
Accounts Receivable shall be reduced by the amount of any reserve or allowance
for doubtful accounts, returned products or potential price adjustments,
transferred to the Partnership pursuant to Section 2.1(j); and provided,
further, that any payments or reimbursements that are made by the Partnership
as a result of volume or price rebates or adjustments and that are attributable
(in whole or in part) to transactions prior to the Closing Date shall be for
the account of the Contributor (or, in the case of Oxy Petrochemicals, Oxy CH
Sub), to the extent so attributable.  Collections on Accounts Receivable shall
be applied on a specific identification basis.  The Partnership will report
monthly in writing to each Contributor (or, in the case of Oxy Petrochemicals,
Oxy CH Sub) on the amounts collected during the preceding month, and shall
provide an aging summary of uncollected





                                     - 26 -
   32
accounts and a detailed description of each problem account (45 or more days
overdue).  On reasonable notice to the Partnership, each Contributor (or, in
the case of Oxy Petrochemicals, Oxy CH Sub) shall have the right to take over
the collection process for any problem account.

         5.7     Reimbursement for Prepaid Expenses.  The Partnership and each
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 such Contributor
(or, in the case of Oxy Petrochemicals, Oxy CH Sub) 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 Assignment and Assumption
Agreements.  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, each Asset
Contributor and Oxy CH Sub hereby agrees, to the fullest extent permitted by
applicable law, to indemnify, defend and hold harmless the Partnership, its
partners, their 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 a Contributor, Oxy CH Sub or any of
         its Affiliates in this Agreement, the Assignment and Assumption
         Agreements, the Master Intellectual Property Agreement, or the Master
         Transaction Agreement, provided that any Liability arising out of, in
         connection with or relating to any breach of the warranties in any
         Assignment and Assumption Agreement that





                                     - 27 -
   33
         is not a breach of the warranties in this Agreement shall not be
         indemnified against pursuant to this Section 6;

                 (ii)     Any failure of a Contributor, Oxy CH Sub 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
indemnification obligations in clauses (i) and (iv) above:

                 (A)      the Asset Contributors and Oxy CH Sub, in the
         aggregate, 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 a Contributor or Oxy CH Sub
         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, NO ASSET CONTRIBUTOR, OXY CH SUB OR ANY OF
THEIR AGENTS, EMPLOYEES, REPRESENTATIVES OR AFFILIATES SHALL BE LIABLE FOR
CONSEQUENTIAL, INCIDENTAL, INDIRECT OR PUNITIVE DAMAGES IN CONNECTION WITH
DIRECT CLAIMS BY AN INDEMNIFIED PARTY (I.E., A CLAIM BY AN INDEMNIFIED PARTY
THAT DOES NOT SEEK REIMBURSEMENT FOR A THIRD PARTY CLAIM PAID OR PAYABLE BY
SUCH INDEMNIFIED PARTY) WITH RESPECT TO

THEIR INDEMNIFICATION OBLIGATIONS UNDER THIS AGREEMENT UNLESS ANY SUCH CLAIM
ARISES OUT OF THE FRAUDULENT ACTIONS OF AN ASSET CONTRIBUTOR OR OXY CH SUB.  IN
DETERMINING THE AMOUNT OF ANY LOSS, LIABILITY, OR EXPENSE FOR WHICH AN
INDEMNIFIED PARTY 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 SUCH
INDEMNIFIED PARTY UNDER POLICIES TO THE EXTENT THAT THE FUTURE PREMIUM RATE
WILL NOT BE INCREASED BY CLAIM EXPERIENCE RELATING TO SUCH LOSS, LIABILITY OR
EXPENSE.

         (c)     Notwithstanding the provisions of Sections 6.2(a)(i) and
6.2(a)(iv), it is expressly agreed that no Asset Contributor or Oxy CH Sub
shall 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 each
Asset Contributor, Oxy CH Sub and their Affiliates and their respective
officers, directors and employees against and agrees to hold each of them
harmless from any and all Liability incurred or suffered by such Person 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, the Assignment and Assumption Agreements,
         the Master Intellectual Property Agreement or the Master Transaction
         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 AN
INDEMNIFIED PARTY (I.E., A CLAIM BY AN INDEMNIFIED PARTY THAT DOES NOT SEEK
REIMBURSEMENT FOR A THIRD

   35
PARTY CLAIM PAID OR PAYABLE BY SUCH INDEMNIFIED PARTY ) 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 AN INDEMNIFIED PARTY 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 SUCH INDEMNIFIED PARTY UNDER POLICIES TO THE
EXTENT THE FUTURE PREMIUM RATE WILL NOT BE INCREASED BY CLAIM EXPERIENCE
RELATING TO SUCH LOSS, LIABILITY OR EXPENSE.

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





                                     - 30 -
   36
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





                                     - 31 -
   37
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 any or all Contributors 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 appropriate Contributors 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
Contributors 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
