warranties or other Assets so made available to the Partnership. If an Asset
Contributor obtains a Consent to assign any Government Licenses, Contributed

      2.8 Employee Matters.
          ---------------- 

     (a) "Employees" shall mean all employees of a Contributor or an Affiliate
whose work relates primarily to the Assets or the Contributed Business and who
are immediately prior to the Closing in the active employment of a Contributor
or an Affiliate.  A true and complete list of names; positions; salaries or
hourly wage rates, as applicable; years of service, and the last bonus of the
Employees shall be provided by a Contributor or its designee to the Partnership
from time to time up to the Closing.  In accordance with and subject to Section
3.6 of the Master Transaction Agreement, as of the Expiration Date, the
Partnership shall offer employment to certain Employees who are immediately
prior to the Expiration Date in the active employment of a Contributor or an
Affiliate pursuant to a schedule prepared by the Contributors prior to the
Closing Date and agreed to by the Partnership.  The Partnership agrees that no
Employee will fail to receive an offer of employment from the Partnership unless
the Contributor or Affiliate employing such Employee has given its approval,
which approval shall not be unreasonably withheld.  Any such Employee that
accepts such offer is herein called a "Partnership Employee."  Partnership
Employees shall be employed effective as of the Expiration Date, except as
otherwise provided in Section 2.8(e).  The Contributors agree that, from the
Expiration Date until December 31, 1998, the Contributors, Occidental or an
Affiliate shall provide payroll services and benefit plan administration for
Partnership Employees, subject to the terms of any agreement for transition
services between the Partnership and OCC.

     (b) Except with respect to employees of a Contributor or any Affiliate
thereof located in Occidental's Dallas, Texas facility ("Non-Plant Employees"),
if, within six months after the Expiration Date or in anticipation of the
Expiration Date, a Contributor or any Affiliate thereof terminates (other than
for cause) the employment of any Employee who does not become a Partnership
Employee, then the Partnership will pay to such Contributor an amount, not to
exceed the Basic Severance, to the extent such Contributor or any Affiliate
thereof pays severance to such employee under any plan or policy of the
Contributor or Affiliate.  "Basic Severance" means a severance payment according
to the severance pay formula as set forth in Schedule 2.8(b). The  

                                      -11-

 
Contributors shall remain responsible for all severance and other compensation
or payment to Non-Plant Employees who do not become Partnership Employees and
for bonus or other executive compensation, if any, to plant employees covered by
Occidental's bonus or executive compensation programs. The Contributors shall
pay bonus or executive compensation payable to Partnership Employees on a pro-
rata basis determined based on the Partnership Employee's months of employment
with a Contributor prior to the Expiration Date.

     (c) Any Partnership Employee whose employment is terminated by the
Partnership (other than for cause) within six months after the Expiration 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 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-

 
          (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 

                                      -13-

 
     be provided after the 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

                                      -14-

 
earnings or losses on such 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 

                                      -15-

 
of the Contributor at the Beaumont, Texas, PD Glycol Plant. Further, the
Partnership will recognize 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 

                                      -16-

 
attorney's fees) arising out of or otherwise in respect of the following (i) any
Contributor employee 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 Partnership by such
Asset Contributor or its Affiliates pursuant to other 

                                      -17-

 
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
such Asset Contributor or its Affiliates.

                                   SECTION 3
               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 

                                      -18-

 
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 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 

                                      -19-

 
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 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

                                      -20-

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

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

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.

            --------------------                                                
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,

                                      -27-

 
          (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

          (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 

                                      -28-

 
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

WILL NOT BE INCREASED BY CLAIM EXPERIENCE RELATING TO SUCH LOSS, LIABILITY OR
EXPENSE.

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.

                                      -29-

 
     (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 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 62 (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.

                                      -30-

 
     (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
63 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 

                                      -31-

 
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 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.

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


     (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 Contributors 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) Any party to this Agreement 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 other party or parties to the
Dispute, 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
other party or parties.  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 subsections (d), (e) and (f).

     (d) After satisfying the requirements above, such Dispute shall be
submitted to mandatory and binding arbitration at the election of any party
involved in the Dispute (the "Disputing Party"). 

 
The arbitration shall be subject to the Federal Arbitration Act as supplemented
by the conditions set forth in this Appendix. The arbitration shall be conducted
in accordance with the Commercial Arbitration Rules of the American Arbitration
Association in effect on the date the notice of arbitration is served, other
than as specifically modified herein. In the absence of an agreement to the
contrary, the arbitration shall be held in Houston, Texas. The Arbitrator (as
defined below) will allow reasonable discovery in the forms permitted by the
Federal Rules of Civil Procedure, to the extent consistent with the purpose of
the arbitration. During the pendency of the Dispute, each party shall make
available to the Arbitrator and the other parties all books, records and other
information within its control requested by the other parties or the Arbitrator
subject to the confidentiality provisions contained herein, and provided that no
such access shall waive or preclude any objection to such production based on
any privilege recognized by law. Recognizing the express desire of the parties
for an expeditious means of dispute resolution, the Arbitrator may limit the
scope of discovery between the parties as may be reasonable under the
circumstances. In deciding the substance of the parties' claims, the laws of the
State of Delaware shall govern the construction, interpretation and effect of
this Agreement (including this Appendix) without giving effect to any conflict
of law principles. The arbitration hearing shall be commenced promptly and
conducted expeditiously, with each party involved in the Dispute being allocated
an equal amount of time for the presentation of its case. Unless otherwise
agreed to by the parties, the arbitration hearing shall be conducted on
consecutive days. Time is of the essence in the arbitration proceeding, and the
Arbitrator shall have the right and authority to issue monetary sanctions
against any of the parties if, upon a showing of good cause, that party is
unreasonably delaying the proceeding. To the fullest extent permitted by law,
the arbitration proceedings and award shall be maintained in confidence by the
Arbitrator and the parties.

     (e) The Disputing Party shall notify the American Arbitration Association
("AAA")  and the other parties involved in the Dispute in writing describing in
reasonable detail the nature of the Dispute (the "Dispute Notice").  The
arbitrator (the "Arbitrator") shall be selected within 15 days of the date of
the Dispute Notice by all of the parties from the members of a panel of
arbitrators of the AAA or, if the AAA fails or refuses to provide a list of
potential arbitrators, of  the Center for Public Resources and shall be
experienced in commercial arbitration.  In the event that the parties are unable
to agree on the selection of the Arbitrator, the AAA shall select the
Arbitrator, using the criteria set forth in this Appendix, within 30 days of the
date of the Dispute Notice.  In the event that the Arbitrator is unable to
serve, his or her replacement will be selected in the same manner as the
Arbitrator to be replaced.  The Arbitrator shall be neutral.  The Arbitrator
shall have the authority to assess the costs and expenses of the arbitration
proceeding (including the arbitrators', and attorneys' fees and expenses)
against any or all parties.

     (f) The Arbitrator shall decide all Disputes and all substantive and
procedural issues related thereto, and shall enforce this Agreement in
accordance with its terms.  Without limiting the generality of the previous
sentence, the Arbitrator shall have the authority to issue injunctive relief;
however, the Arbitrator shall not have any power or authority to (i) award
consequential, incidental, indirect or punitive damages or (ii) amend this
Agreement.  The Arbitrator shall render the arbitration award, in writing,
within 20 days following the completion of the arbitration hearing, and shall
set forth the reasons for the award.  In the event that the Arbitrator awards
monetary damages 

 
in favor of either party, the Arbitrator must certify in the award that no
indirect, consequential, incidental, indirect or punitive damages are included
in such award. If the Arbitrator's decision results in a monetary award, the
interest to be granted on such award, if any, and the rate of such interest
shall be determined by the Arbitrator in his or her discretion. The arbitration
award shall be final and binding on the parties, and judgment thereon may be
entered in any court of competent jurisdiction, and may not be appealed except
to the extent permitted by the Federal Arbitration Act.

          (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 Arbitrator shall determine to be appropriate under the
circumstances.
