ITEM 2.       ACQUISITION OR DISPOSITION OF ASSETS.

On April 30, 1999, The Geon Company (Geon or the Company) formed two
partnerships (Partnerships) with Occidental Chemical Corporation (OxyChem),
named Oxy Vinyls, LP (OxyVinyls or PVC Partnership) and PVC Powder Blends, LP
(PVC Powder Blends or Compounding Partnership). OxyVinyls is owned 24% by Geon
and 76% by OxyChem. The partnership combines the polyvinyl chloride (PVC) resin
and vinyl chloride monomer (VCM) businesses and related operations of both
companies, and also includes OxyChem's Houston Chlor-Alkali complex. OxyVinyls
will be North America's largest and the world's third largest PVC producer. PVC
Powder Blends is owned 90% by Geon and 10% by OxyChem. The Compounding
Partnership will manufacture dry-blend compounds.

In conjunction with the formation of the Partnerships Geon realized
approximately $104 million in cash and working capital retention and transferred
$189 million of debt obligations to OxyVinyls, and OxyChem transferred its PVC
flexible film and specialty pellet compound businesses located in Burlington,
New Jersey and Pasadena, Texas to the Company (Related Transactions).

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Board of Directors,
Occidental Chemical Corporation:

We have audited the accompanying combined balance sheets of the OxyChem
Transferred Businesses, as defined in Note 1, as of December 31, 1998 and 1997,
and the related combined statements of operations and invested capital and cash
flows for each of the three years in the period ended December 31, 1998. These
financial statements are the responsibility of Occidental Chemical Corporation's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the OxyChem Transferred
Businesses as of December 31, 1998 and 1997, and the related combined statements
of operations and invested capital and cash flows for each of the three years in
the period ended December 31, 1998, in conformity with generally accepted
accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS

                        December 31, 1998, 1997 and 1996



(1)      BASIS OF PRESENTATION AND DESCRIPTION OF THE TRANSFERRED BUSINESSES -

         On June 24, 1998, Occidental Chemical Corporation (together with its
wholly-owned subsidiaries, "OxyChem") signed a letter of intent with The Geon
Company (together with its wholly-owned subsidiaries, "Geon") to effect, among
other things, the proposed formation by Geon and OxyChem of two separate limited
partnerships, focusing on the suspension/mass polyvinyl chloride ("PVC") and
vinyl chloride monomer ("VCM") businesses, together with OxyChem's Houston
Chlor-Alkali Complex and the powder/dry blend compound business, respectively,
and the transfer of a compound and flexible film plant and a pellet compound
business by OxyChem to Geon, as well as certain related supply arrangements. The
formation of each entity will involve the contribution by both Geon and OxyChem
of such assets, together with certain related assets and liabilities as well as
the transfer of related employees. All of the foregoing transactions shall be
referred to collectively hereinafter as the "Proposed Transactions."

         OxyChem's transfers to the Proposed Transactions include the following:

         1.              OxyChem and Geon will form a limited partnership (the 
                  "PVC Partnership") to which OxyChem will contribute its PVC
                  and VCM facilities in Pasadena, Texas, and Deer Park, Texas,
                  as well as a fifty percent investment interest in OxyMar, a
                  partnership which manufactures VCM at its plant in Ingleside,
                  Texas. OxyMar is owned by an OxyChem affiliate, Oxy VCM, Inc.
                  Additionally, OxyChem will contribute its Houston Chlor-Alkali
                  Complex facilities to the PVC Partnership.

         2.              OxyChem and Geon will also form a limited partnership 
                  (the "Compounding Partnership") to which OxyChem will
                  contribute its powder compound business and related assets at
                  its Pasadena, Texas, facility.

         3.              OxyChem's specialty cube or pellet compound business 
                  being constructed and installed at its Pasadena, Texas, plant
                  ("Pasadena Subject Business"), and its Burlington, New Jersey,
                  plant, which manufactures flexible film and compound (the
                  "Burlington Plant"), will be conveyed to Geon.

         In return for the contributions and transfers of assets mentioned
above, OxyChem will acquire a 76% controlling interest in the PVC Partnership
and a 10% non-controlling interest in the Compounding Partnership. Under the
Proposed Transactions, the PVC Partnership and the Compounding Partnership will
also assume certain liabilities of OxyChem.

         The accompanying combined financial statements include the assets and
liabilities and results of operations of OxyChem's contributions to the PVC
Partnership and the Compounding Partnership as well as the Pasadena Subject
Business, the Burlington Plant and Oxy VCM, Inc. (collectively, the "OxyChem
Transferred Businesses"). The OxyChem Transferred Businesses are represented by
OxyChem and Oxy VCM, Inc., which are indirect subsidiaries of Occidental
Chemical Holding Corporation ("OCHC"). OCHC is an indirect subsidiary of
Occidental Petroleum Corporation ("OPC"). Certain amounts in the accompanying
combined financial statements have been allocated in a consistent manner in
order to depict the financial position, results of operations and cash flows of
the OxyChem Transferred Businesses on a stand alone basis. OxyChem's management
believes these allocations are reasonable. Consequently, the financial position,
results of operations, and cash flows may not be indicative of what would have
been reported if the OxyChem Transferred Businesses had been one or more
separate, stand-alone entities or had been operated as a part of the Proposed
Transactions during the periods presented.

                     NOTES TO COMBINED FINANCIAL STATEMENTS

                        December 31, 1998, 1997 and 1996


(1)      BASIS OF PRESENTATION AND DESCRIPTION OF THE TRANSFERRED BUSINESSES -
         (continued)

         Certain assets and liabilities of the OxyChem Transferred Businesses
will be retained by OPC or OxyChem after closing of the Proposed Transactions.
The retained assets and liabilities include certain trade receivables and
finished goods inventory, long-term debt, property tax, and other liabilities.
The amount of assets and liabilities that would have been retained was
approximately $7 million and $47 million, respectively, at December 31, 1998.

         The OxyChem Transferred Businesses operate as OxyChem and enter into
operating and sales contracts administered by OxyChem. These include national
sales agreements as well as purchase and energy agreements.


(2)      SIGNIFICANT ACCOUNTING POLICIES -

     Principles of combination  -

         The combined financial statements include the assets and liabilities
and results of operations of the OxyChem Transferred Businesses. All material
intercompany accounts and transactions between the OxyChem Transferred
Businesses have been eliminated.

     Risks and uncertainties -

         The process of preparing financial statements in conformity with
generally accepted accounting principles requires the use of estimates and
assumptions regarding certain types of assets, liabilities, revenues and
expenses. Such estimates primarily relate to unsettled transactions and events
as of the date of the financial statements. Accordingly, upon settlement, actual
results may differ from estimated amounts, generally not by material amounts.
OxyChem's management believes that these estimates and assumptions, as well as
any allocations, provide a reasonable basis for the fair presentation of the
OxyChem Transferred Businesses' combined financial position and results of
operations.

         Since the OxyChem Transferred Businesses' major products are
commodities, significant changes in the prices of chemical products could have a
significant impact on the OxyChem Transferred Businesses' results of operations
for any particular period.

     Revenue recognition  -

         Revenue from product sales is recognized upon shipment of product to
the customer.

     Environmental liabilities and costs -

         Environmental expenditures that relate to current operations are
expensed or capitalized as appropriate. Reserves for estimated costs that relate
to existing conditions caused by past operations and that do not contribute to
current or future revenue generation are recorded when environmental remedial
efforts are probable and the costs can be reasonably estimated. In determining
the reserves, OPC uses the most current information available, including similar
past experiences, available technology, regulations in effect, the timing of
remediation and cost-sharing arrangements. The environmental reserves are based
on management's estimate of the most likely cost to be incurred and are reviewed
periodically and adjusted as additional or new information becomes available.

(2)      SIGNIFICANT ACCOUNTING POLICIES - (continued)

     Equity investment  -

         The OxyChem Transferred Businesses' fifty percent interest in OxyMar is
accounted for on the equity method. At December 31, 1998 and 1997, the
historical underlying equity in net assets of OxyMar exceeded the OxyChem
Transferred Businesses' investment in OxyMar by $8.3 million and $8.8 million,
respectively. The investment deficiency is being amortized on a straight-line
basis into income over 25 years. The following table presents summarized
financial information of OxyMar as of December 31, 1998 and 1997, and for the
years ended December 31, 1998, 1997 and 1996 (in thousands).

</TABLE>

         As of December 31, 1998, OPC unconditionally provides guarantees of
$192.5 million of the OxyMar partnership obligations, which includes bonds and a
revolving credit line.

     Income taxes -

         The OxyChem Transferred Businesses have been included in the
consolidated U.S. federal income tax return and in certain unitary state income
tax returns of OPC. A portion of the income tax provision for these returns is
allocated to the OxyChem Transferred Businesses on the basis of a tax sharing
arrangement with OPC using net income determined on a separate tax return basis.
Income tax provisions under the tax sharing arrangement are calculated using the
applicable U.S. federal statutory rate and a unitary state effective rate (based
on unitary state income taxes incurred by OPC and subsidiaries).

         The OxyChem Transferred Businesses also record state income tax
provisions for operations required to be reported in separate tax returns. The
difference between the provision for income taxes at the U.S. federal statutory
rate and the effective tax rate is primarily due to state income taxes.
Liabilities for current and/or deferred income taxes have been and remain the
responsibility of OPC and, accordingly, have been included in the Combined
Balance Sheets as invested capital.

     Fair value of financial instruments -

         The fair value of on-balance sheet financial instruments approximates
carrying value.

(2)      SIGNIFICANT ACCOUNTING POLICIES - (continued)

     Asset impairment  -

         During 1997, OxyChem decided to sell the Burlington Plant after
determining it to be a non-strategic asset. OxyChem estimated its fair value
based on discussions with prospective buyers adjusted for selling costs. OxyChem
reduced its carrying value by $32.8 million to record the assets held for sale
at fair value. The charge for this write-down is included in selling, general
and administrative and other operating expenses in the accompanying Combined
Statement of Operations and Invested Capital. Management believes there will be
no additional write-down resulting from the sale of the Burlington Plant to
Geon.


(3)      RECEIVABLES -

         As of December 31, 1998 and 1997, the OxyChem Transferred Businesses
transferred, with limited recourse, to an OPC affiliate certain trade
receivables under a revolving sale program in connection with the ultimate sale
for cash of an undivided ownership interest in such receivables by the
affiliate. The net receivables transferred amounted to approximately $98 million
and $85 million as of December 31, 1998 and 1997, respectively. The OxyChem
Transferred Businesses transferred the receivables to the affiliate in a noncash
transaction that was reflected as a reduction in invested capital. OPC retained
collection responsibility with respect to the receivables sold. An interest in
newly created receivables is transferred monthly, net of collections made from
customers. Fees related to the sales of receivables under this program, which
are allocated from OPC to the OxyChem Transferred Businesses, were $4.8 million,
$3.9 million and $3.2 million for 1998, 1997 and 1996, respectively, and are
included in other expense, net.


(4)      INVENTORIES -

         Inventories are valued at the lower of cost or market. The last-in,
first-out (LIFO) cost method was used in determining the costs of raw materials
and finished goods. Materials and supplies inventories were determined using the
weighted-average-cost method. Inventories consisted of the following as of
December 31 (in thousands):

(5)      PROPERTY, PLANT AND EQUIPMENT -

         Property additions and major renewals and improvements are capitalized
at cost. Depreciation is primarily provided using the units-of-production method
based on estimated total productive life.

         Interest costs incurred in connection with major capital expenditures
which extend longer than one year are capitalized and amortized over the lives
of the related assets. Capitalized interest is calculated based on the average
borrowing rate of OPC and allocated to the OxyChem Transferred Businesses.
Interest allocated and capitalized was approximately $1 million, $6 million and
$2 million for the years ended December 31, 1998, 1997 and 1996, respectively.

         Property, plant and equipment consists of the following as of December

</TABLE>

         Deferred start-up costs are amortized over a period of 10 years. Other
amortizable assets are written off to income over the estimated periods to be
benefited.

         In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities" (SOP 98-5), which requires that costs of start-up activities,
including organizational costs, be expensed as incurred. The initial application
of the statement will result in a charge to income for any costs of start-up
activities that have not yet been fully amortized. OPC will implement SOP 98-5
effective January 1, 1999.

</TABLE>

         Maintenance turnarounds are generally performed every 2 to 5 years.
OxyChem utilizes an accrual methodology under which it estimates the projected
cost of a turnaround and accrues the cost equally over the years between
turnarounds. Turnaround costs charged to operations for the years ended December
31, 1998, 1997 and 1996 were $7.7 million, $8.0 million, and $7.3 million,
respectively.

</TABLE>

         Unamortized discount is being amortized to interest expense over the
lives of the related issues.

         Certain of the pollution control revenue bonds are secured by the
equipment purchased with the proceeds of the bond financing.

         At December 31, 1998, $8 million of the long-term debt was guaranteed
by OPC.

(9)      RETIREMENT PLANS AND POSTRETIREMENT BENEFITS -

         Effective January 1, 1998, OPC adopted the provisions of SFAS No. 132
"Employers' Disclosures about Pensions and Other Postretirement Benefits." This
statement standardized the disclosure requirements for pensions and other
postretirement benefits and amends SFAS No. 87 "Employers' Accounting for
Pensions," SFAS No. 88 "Employers' Accounting for Settlements and Curtailments
of Defined Benefit Pension Plans" and SFAS No. 106 "Employers' Accounting for
Postretirement Benefits Other Than Pensions". The provisions of SFAS No. 132 are
disclosure oriented and do not change the measurement or recognition of the
plans. Accordingly, the implementation of SFAS No. 132 did not have an impact on
the OxyChem Transferred Businesses' combined financial position or results of
operations. The prior disclosures for 1997 have been changed to conform to the
new disclosure requirements.

         The OxyChem Transferred Businesses participate in various defined
contribution retirement plans sponsored by OPC for its salaried, domestic union
and nonunion hourly, and certain foreign national employees that provide for
periodic contributions by the OxyChem Transferred Businesses based on
plan-specific criteria, such as base pay, age level, and/or employee
contributions. The OxyChem Transferred Businesses contributed and expensed
approximately $5 million under the provisions of these plans in each of the
years 1998, 1997 and 1996.

         OPC provides medical and dental benefits and life insurance coverage
for certain active, retired and disabled employees and their eligible
dependents. Beginning in 1993, certain salaried participants pay for all medical
cost increases in excess of increases in the consumer Price Index (CPI). The
benefits generally are funded by OPC as the benefits are paid during the year.
The cost of providing these benefits is based on claims filed and insurance
premiums paid for the period.

         The OxyChem Transferred Businesses' retirement and postretirement
defined benefit plans are accrued based on various assumptions and discount
rates, as described below. The actuarial assumptions used could change in the
near term as a result of changes in expected future trends and other factors
which, depending on the nature of the changes, could cause increases or
decreases in the liabilities accrued.

     Retirement plans  -

         Pension costs for the OxyChem Transferred Businesses' defined benefit
pension plans, determined by independent actuarial valuations, are generally
funded by payments to trust funds, which are administered by independent
trustees. The following table sets forth the components of the net periodic
benefit costs for the OxyChem Transferred Businesses' defined benefit pension
plans for the years ended December 31 (in thousands):

(9)      RETIREMENT PLANS AND POSTRETIREMENT BENEFITS - (continued)

     Postretirement benefits -

         To reflect the OxyChem Transferred Businesses' participation in the OPC
plan, the net periodic postretirement benefit costs and the postretirement
benefit obligations are based on an allocation of the OPC actuarial study using
participant counts and demographic information for the OxyChem Transferred
Businesses for each of the years presented in the tables below. This allocation
excludes amounts attributable to salaried retirees and surviving spouses because
nonunion retiree information is not maintained for such participants by plant
location.

         The postretirement benefit obligation as of December 31, 1998 and 1997
was determined by application of the terms of medical and dental benefits and
life insurance coverage, including the effect of established maximums on covered
costs, together with relevant actuarial assumptions and health care cost trend
rates projected at a CPI increase of 2.5 percent and 3 percent as of December
31, 1998 and 1997, respectively (beginning in 1993, participants other than
certain union employees pay for all medical cost increases in excess of
increases in the CPI). For certain union employees, the health care cost trend
rates were projected at annual rates ranging ratably from 8 percent in 1998 to 5
percent through the year 2004 and level thereafter. A one percent increase or a
one percent decrease in these assumed health care cost trend rates would result
in an increase of $1 million or a reduction of $1 million, respectively, in the
postretirement benefit obligation as of December 31, 1998. The annual service
and interest costs would not be materially affected by these changes. The
weighted average discount rate used in determining the accumulated
postretirement benefit obligation was 7 percent in 1998 and 7.5 percent in 1997.
The plans are unfunded.

         The following table sets forth the components of the allocated net
periodic benefit costs for the OxyChem Transferred Businesses' defined
postretirement benefit plans for the years ended December 31 (in thousands):

     Lawsuits -

         OxyChem has been named as defendant or as a potentially responsible
party with regard to the OxyChem Transferred Businesses in a number of lawsuits,
claims and proceedings, including governmental proceedings under the
Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA")
and corresponding state acts. OxyChem has accrued reserves with regard to the
OxyChem Transferred Businesses at the most likely cost to be incurred, if any.
In management's opinion, after taking into account reserves and indemnities, it
is unlikely that any of the foregoing matters will have a material adverse
effect upon the combined financial position or results of operations of the
OxyChem Transferred Businesses.

         Payments under this agreement were $880,000, $909,000 and $939,000 in
1998, 1997 and 1996, respectively.

         The OxyChem Transferred Businesses have certain other commitments to
purchase electrical power, raw materials and other potential obligations, all in
the ordinary course of business.


(11)     RELATED PARTY TRANSACTIONS -

         OPC utilizes a centralized cash management system for its operations,
including the OxyChem Transferred Businesses. Cash distributed to or advanced
from OPC has been reflected in invested capital in the accompanying Combined
Balance Sheets. In addition, settlements of transactions with other OPC
affiliates are recorded through invested capital.

         OPC provided certain corporate, general and administrative services to
the OxyChem Transferred Businesses, including legal, financial, marketing, sales
and customer service, technical, executive and other services. Charges for these
services were allocated based on ratios in a reasonable and consistent manner
and by the estimated costs of specific functions performed by OPC and affiliates
for the OxyChem Transferred Businesses. OxyChem's management believes the
allocations, which totaled $41.7 million in 1998, $41.9 million in 1997 and
$41.6 million in 1996, are reasonable. Such amounts are included in selling,
general and administrative and other operating expenses.

         The OxyChem Transferred Businesses were also allocated research and
development costs by OxyChem, which are charged to operations as incurred. These
charges, which are included in selling, general and administrative and other
operating expenses in the accompanying Combined Statements of Operations and
Invested Capital, were $2.6 million, $2.5 million and $1.6 million for 1998,
1997 and 1996, respectively.

         The OxyChem Transferred Businesses sell to other OxyChem facilities and
affiliated businesses of OPC. These sales, reflected at market prices and
included in the accompanying Combined Statements of Operations and Invested
Capital, were approximately $49 million, $69 million and $68 million for 1998,
1997 and 1996, respectively.

  Partnership to the Compounding Partnership have been eliminated in combining
  the OxyChem Transferred Businesses.

ITEM 7B.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS OF THE GEON
COMPANY

The unaudited pro forma condensed consolidated financial statements of Geon
reflect the formation of the Partnerships and Related Transactions as if they
had been completed on December 31, 1998 for pro forma balance sheet data
purposes and on January 1, 1998, for pro forma income statement data purposes.
The Unaudited Pro Forma Condensed Consolidated Statement of Income includes
amounts derived from the audited consolidated statement of income of Geon for
the year ended December 31, 1998 and the audited combined statement of
operations of the OxyChem Transferred Businesses for the year ended December 31,
1998. The Unaudited Pro Forma Condensed Consolidated Balance Sheet includes
amounts derived from the audited consolidated balance sheet of Geon and the
audited combined balance sheet of the OxyChem Transferred Businesses as of
December 31, 1998. OxyChem's transfer of its PVC flexible film and specialty
pellet compound businesses to Geon and OxyChem's business contributed to the
Compounding Partnership are collectively referred to as the "Acquired
Businesses" in the accompanying Unaudited Pro Forma Condensed Consolidated
Financial Statements.

For accounting purposes, Geon's interest in the PVC Partnership is reflected on
the equity basis. Geon's majority ownership of the Compounding Partnership
requires the assets and liabilities contributed by OxyChem to the Compounding
Partnership to be valued at their estimated fair value in Geon's consolidated
financial statements. OxyChem's transfer of its PVC flexible film and specialty
pellet compound businesses to Geon requires the assets and liabilities
transferred to be valued at their estimated fair value in Geon's consolidated
financial statements. Certain pro forma adjustments result from a preliminary
determination of purchase accounting adjustments and are based upon information
provided by management of OxyChem and certain assumptions that management of
Geon considers reasonable under the circumstances. Consequently, the amounts
reflected in Geon's Unaudited Pro Forma Condensed Consolidated Financial
Statements are subject to change.

The contributions by Geon to the PVC Partnership and the Compounding Partnership
will trigger the recognition of an after-tax gain (estimated to be $53 million
on a pro forma basis) in the second quarter of 1999. Such contributions include,
for accounting purposes, a sale to OxyChem of 76% of Geon's PVC business
contributed to the PVC Partnership and a sale to OxyChem of 10% of Geon's
compounding business contributed to the Compounding Partnership. The resultant
gain represents the excess of fair value (including the realization of a net
$104 million in cash and working capital retention benefits from the PVC
Partnership) over book value for the 76% and 10% of Geon's PVC and Compounding
Contributed Businesses, respectively.

</TABLE>

The $6 million reduction in the net cash and working capital retention benefits
result from the contribution of $4 million of additional debt and lease
obligations plus $2 million which represents Geon's funding of a portion of the
LaPorte plant maintenance shutdown scheduled for the second quarter of 1999
after formation of the PVC Partnership.

The Unaudited Pro Forma Condensed Consolidated Financial Statements of Geon and
the accompanying notes should be read in conjunction with the audited
consolidated financial statements of Geon as of and for the year ended December
31, 1998 and the audited combined financial statements of the OxyChem
Transferred Businesses as of and for the year ended December 31, 1998 which are
included herein.

The Unaudited Pro Forma Condensed Consolidated Financial Statements of Geon do
not purport to be indicative of what Geon's financial condition or results of
operations would have been had the formation of the Partnerships and Related
Transactions in fact been consummated as of the assumed dates and for the
periods presented, nor are they indicative of the results of operations or
financial condition for any future period or date. The pro forma adjustments
reflected in the Unaudited Pro Forma Condensed Consolidated Financial Statements
to give effect to the formation of the Partnerships and Related Transactions,
are based on available information and certain assumptions that Geon believes
are reasonable in the circumstances.

NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED STATEMENTS OF INCOME (IN
MILLIONS):

(a)  To reflect the sum of Geon's 24% share of the pro forma PVC Partnership
     loss for the period and the amortization of the difference between the
     carrying value of Geon's investment in and its underlying equity in the PVC
     Partnership. Geon's share of the loss from the PVC Partnership has also
     been adjusted by the amount of supplemental pension benefit costs
     associated with former Geon personnel who continue employment with the PVC
     Partnership. Such benefits will be paid by Geon.

     Such loss is computed as follows:

following:

(i)    The one time estimated after tax gain of $53 million resulting from
       Geon's contributions to the PVC Partnership and the Compounding
       Partnership, which for accounting purposes are treated as a sale to
       OxyChem of 76% of Geon's PVC Businesses contributed to the PVC
       Partnership and a sale to OxyChem of 10% of Geon's Compounding Business
       contributed to the Compounding Partnership. The resultant gain represents
       the excess of fair value (including cash received of $78 million) over
       the book value of the 76% and 10% of Geon's PVC and Compounding
       Contributed Businesses, respectively.

(ii)  The synergies and the cost of such synergies expected to be realized by
      Geon as a result of the formation of the Partnerships and Related
      Transactions. Geon expects its share of the synergies and the cost of such
      synergies resulting from the PVC Partnership to approximate $20 million 
      and $4 million, respectively, and the synergies and related costs of the
      synergies related to the Compounding Partnership to approximate $7 million
      and $3 million, respectively. The synergies are expected to be fully
      realized in 2001, and the costs of such synergies are expected to be
      incurred in 1999 and 2000. Such synergies, as they relate to the PVC
      Partnership, are expected to be realized from cost reductions resulting
      from production, logistics, and distribution efficiencies; the
      consolidation of production facilities, reductions in executive management
      positions and related compensation and benefits; elimination of duplicate
      overhead, staffing and information systems costs; the consolidation of
      research and development facilities, as well as, legal, environmental,
      health and safety and risk management services; and reductions in the cost
      of property and liability insurance coverage. The synergies related to the
      Compounding Partnership are expected to be realized through the reduction
      of excess production capacity, the benefits resulting from the volume
      purchasing of materials, and the reduction of selling, general and
      administrative costs.

(iii) The charges and expected cost savings associated with the completion of
      Geon's consolidation of its compounding operations.

In the first quarter of 1999, the Company will recognize costs totaling $1.7
million relating to the completion of the compound consolidation plan previously
announced in 


                                       31
<PAGE>   33
November 1998. Such costs consist of $0.6 million of accelerated depreciation on
software assets to be taken out of service in the second quarter of 1999, asset
write-offs of $0.4 million, legal and professional fees of $0.5 million and
employee separation costs of $0.2 million.

The Company anticipates incurring, in the second quarter of 1999 and upon
formation of the powder compound partnership, estimated costs totaling $6.0
million relating to the completion of the compound consolidation plan.

The amounts expected to be incurred are as follows:

       accelerated depreciation of $0.6 million and disposition costs of $1.4
       million which will be expensed as incurred, and (b) costs associated with
       exiting Geon's Conroe, Texas, powder compounding facility, which will be
       closed subject to the consummation of the Joint Venture Transactions,
       totaling $4.0 million. The costs of closing the Conroe, Texas, facility
       primarily represent non-cash write-offs of fixed assets with a net book
       value of $2.0 million and other assets with a carrying value of $.5
       million, and cash employee separation costs of approximately $1.5 million
       relating to the termination of 70 individuals. These terminations are
       expected to be completed in the third quarter of 1999.

These costs are in addition to the $14.6 million recorded in the fourth quarter
1998 related to the consolidation of the compounding operations.

The consolidation is projected to produce total cost savings of $6 million in
1999 and $14 million annually thereafter.

                  Geon LP                                 24
                  TOTAL                                  100
</TABLE>

The Units shall entitle the holder to the distributions set forth in Section 3
and to the allocation of Profits, Losses and other items as set forth in Section
4. Units shall not be represented by certificates.

         2.2 PROPERTY CONTRIBUTIONS. On the Closing Date, the Partners shall
make the following capital contributions:

         (a) OCC. Pursuant to the applicable Asset Contribution Agreement, each
of OCC GP and OCC LP will contribute or cause to be contributed to the
Partnership the Initial Assets contemplated thereby subject to the Assumed
Liabilities contemplated thereby. Thereupon, OCC GP's and OCC LP's respective
Capital Accounts will be credited with the amount set forth on Schedule 2.2.

         (b) GEON. Pursuant to the applicable Asset Contribution Agreement, Geon
LP will contribute or cause to be contributed to the Partnership the Initial
Assets contemplated thereby subject to the Assumed Liabilities contemplated
thereby. Thereupon, Geon LP's Capital Account will be credited with the amount
set forth on Schedule 2.2.

The Partners intend that the contribution of assets subject to liabilities
provided for in Sections 2.2(a) and (b) will qualify as a tax-free contribution
under section 721 of the Code in which no Partner will recognize gain or loss.
The Partners agree that the Partnership will so file its tax return, and each
Partner agrees to file its tax return on the same basis and to maintain such
position consistently at all times thereafter.

         2.3 OTHER CONTRIBUTIONS. From time to time and subject to the
limitations of Section 6.7, if applicable, the Partnership Governance Committee
(or the CEO acting pursuant to Section 8.3), on behalf of the Partnership, may
issue a written notice ("Funding Notice") to the Partners calling for an
additional capital contribution to the Partnership. Any Funding Notice will set
forth:

         (a) the use of funds therefor;

         (b) the aggregate amount of the capital contribution required, which
amount shall be apportioned among the Partners Pro Rata; and

                                       4
<PAGE>   10

         (c) the date by which the capital contribution must be received by the
Partnership, which date will not be earlier than seven Business Days from the
date the Funding Notice is issued.

Each Partner shall timely wire transfer its Pro Rata share of the amount set
forth in the Funding Notice to the Partnership's bank account. Except as
expressly set forth in this Agreement, no Partner shall be permitted or required
to make any additional capital contribution to the Partnership.

         2.4 CAPITAL ACCOUNTS. Each Partner's Capital Account shall be
determined and maintained in accordance with Regulation Section
1.704-l(b)(2)(iv). If any Partner transfers all or a portion of its Units in
accordance with the terms of this Agreement, the transferee shall succeed to the
Capital Account of the transferor to the extent such Capital Account relates to
the transferred Units.

         2.5 NO RETURN OF OR ON CAPITAL. Except as provided in Sections 3 and 4,
no Partner shall receive any interest or other return on its capital
contributions or on the balance in its Capital Account and no return of its
capital contributions.

         2.6 PARTNER LOANS. A Partner or its Affiliates may loan funds to the
Partnership on such terms and conditions as may be approved by the Partnership
Governance Committee and, subject to other applicable law, have the same rights
and obligations with respect thereto as a Person who is neither a Partner nor an
Affiliate of a Partner. The existence of such a relationship and acting in such
a capacity will not result in a Limited Partner's being deemed to be
participating in the control of the business of the Partnership or otherwise
affect the limited liability of a Partner. If a Partner or any Affiliate thereof
is a lender, in exercising its rights as a lender, including making its decision
whether to foreclose on property of the Partnership, such lender will have no
duty to consider (i) its status as a Partner or an Affiliate of a Partner, (ii)
the interests of the Partnership or (iii) any duty it may have to any other
Partner or the Partnership.

         2.7 ADMINISTRATION AND INVESTMENT OF FUNDS. The administration and
investment of Partnership funds shall be in accordance with the procedures and
guidelines as shall be adopted by the Partnership Governance Committee. The
Partnership may delegate to a third party (which may be an Affiliate of one of
the Partners) the responsibility for administering and investing Partnership
funds pursuant to such guidelines.


                                    SECTION 3
                                 DISTRIBUTIONS
                                 -------------

         3.1 OPERATING DISTRIBUTIONS. Subject to Section 17-607 of the Act and
other applicable law, distributions to the Partners shall be made as provided in
the Strategic Plan. The Partners contemplate that the Strategic Plan will
provide that, except for debt redemption or prepayment goals contained therein,
the Distributable Cash as of the end of each month shall be distributed to the
Partners Pro Rata.

                                       5
<PAGE>   11

         3.2 LIQUIDATING DISTRIBUTIONS. Distributions to the Partners of cash or
property arising from a liquidation of the Partnership shall be made in
accordance with the Capital Account balances of the Partners as provided in
Section 12.2(d).

         3.3 WITHHOLDING. The Partnership is authorized to withhold from
distributions to a Partner and to pay over to the appropriate foreign, federal,
state or local government tax authority any amounts required to be withheld
pursuant to the Code or any provisions of any other foreign, federal, state or
local law. Any amounts so withheld shall be treated as distributed to such
Partner pursuant to this Section 3 for all purposes of this Agreement, and shall
be offset against any amounts otherwise distributable to such Partner.

         3.4 OFFSET. Any amount otherwise distributable to a Partner pursuant to
this Section 3 shall be applied by the Partnership to satisfy any of the
following obligations that are owed by such Partner or its Affiliate to the
Partnership and that are not paid when due:

         (a) NOTES. In the case of any Partner, the failure to pay any interest
or principal when due on any indebtedness for borrowed money of such Partner or
any Affiliate of such Partner to the Partnership.

         (b) ASSET CONTRIBUTION AGREEMENT. In the case of any Partner, the
failure of such Partner or any Affiliate of such Partner to make any payment
pursuant to Section 5 of its Asset Contribution Agreement that has been Finally
Determined to be due.

         (c) CONTRIBUTION. In the case of any Partner, the failure to make any
capital contribution required pursuant to Section 2.3 (other than pursuant to
its Asset Contribution Agreement).

                            BOOK AND TAX ALLOCATIONS
                            ------------------------

         4.1 GENERAL BOOK ALLOCATIONS. Except as otherwise provided in this
Section 4, Profits or Losses each year shall be allocated among the Partners Pro
Rata for book purposes. As used herein and in Section 4.5(a), "book" means the
allocations used to determine debits and credits to the Capital Accounts of the
Partners as set forth in Section 2.5. It does not refer to the method in which
books are maintained for financial reporting purposes pursuant to Section 5.2.

         4.2 SPECIAL ALLOCATIONS. Depreciation and other amortization with
respect to each Partnership asset acquired pursuant to Section 6.7(iv) shall be
allocated to each Partner in accordance with its contribution, or obligation to
contribute, to the cost of the underlying asset.

         4.3 CHANGE IN PARTNER'S UNITS. If during a year Units are transferred
or new Units issued, allocations among the Partners shall be made in accordance
with their interests in the Partnership from time to time during such year in
accordance with section 706 of the Code, using the closing-of-the-books method,
except that depreciation and other amortization with respect to each Partnership

                                       6
<PAGE>   12


asset shall be deemed to accrue ratably on a daily basis over the entire period
during such year that the asset is owned and in service by the Partnership.

         4.4 DEFICIT CAPITAL ACCOUNT AND NONRECOURSE DEBT RULES. The special
rules in this Section 4.4 apply in the following order to take into account the
possibility of the Partners' having deficit Capital Account balances for which
they are not economically responsible and the effect of the Partnership's
incurring nonrecourse debt, directly or indirectly.

         (a) PARTNERSHIP MINIMUM GAIN CHARGEBACK. If there is a net decrease in
"partnership minimum gain" during any year, determined in accordance with the
tiered partnership rules of Regulation Section 1.704-2(k), each Partner shall
be allocated items of income and gain for such year equal to such Partner's
share of the net decrease in partnership minimum gain within the meaning of
Regulation Sections 1.704-2(g)(2), except to the extent not required by
Regulation Section 1.704-2(f). To the extent that this Section 4.4(a) is
inconsistent with Regulation Section 1.704-2(f) or Section 1.704-2(k) or
incomplete with respect to such regulations, the minimum gain chargeback
provided for herein shall be applied and interpreted in accordance with such
regulations.

         (b) PARTNER MINIMUM GAIN CHARGEBACK. If there is a net decrease in
"partner nonrecourse debt minimum gain" during any year, within the meaning of
Regulation Section 1.704-2(i)(2), each Partner who has a share of such gain,
determined in accordance with Regulation Section 1.704-2(i)(5), shall be
allocated items of income and gain for such year (and, if necessary, subsequent 
years) equal to such Partner's share of the net decrease in partner nonrecourse
debt minimum gain. To the extent that this Section 4.4(b) is inconsistent with
Regulation Section 1.704-2(i) or Section 1.704-2(k) or incomplete with respect
to such regulations, the partner nonrecourse debt minimum gain chargeback
provided for herein shall be applied and interpreted in accordance with such
regulations.

         (c) DEFICIT ACCOUNT CHARGEBACK AND QUALIFIED INCOME OFFSET. If any
Partner has an Adjusted Capital Account Deficit at the end of any year,
including an Adjusted Capital Account Deficit for such Partner caused or
increased by an adjustment, allocation or distribution described in Regulation
Sections 1.704-l(b)(2)(ii)(d)(4), (5) or (6), such Partner shall be allocated
items of income and gain (consisting of a pro rata portion of each item of
Partnership income, including gross income and gain) in an amount and manner
sufficient to eliminate such Adjusted Capital Account Deficit as quickly as
possible. This Section 4.4(c) is intended to constitute a "qualified income
offset" pursuant to Regulation Section 1.704-l(b)(2)(ii)(d) and shall be        
interpreted consistently therewith.

         (d) PARTNER NONRECOURSE DEDUCTIONS. Any partner nonrecourse deductions
for any year or other period shall be allocated to the Partner who bears the
economic risk of loss with respect to the partner nonrecourse debt to which such
partner nonrecourse deductions are attributable in accordance with Regulation
Sections 1.704-2(i) or Section 1.704-2(k).

         (e) CURATIVE ALLOCATIONS. The Allocations provided by this Section 4.4
may not be consistent with the manner in which the Partners intend to allocate
Profits and Losses. Accordingly, Profits and Losses will be reallocated among
the Partners (in the same year and to the extent 

                                       7
<PAGE>   13

necessary, in subsequent years) in a manner consistent with Regulation Section
1.704-l(b) and Section 1.704-2 so as to prevent such allocations from distorting
the manner in which Profits and Losses are intended to be allocated among the
Partners pursuant to Sections 4.1, 4.2, and 4.3.

         (f) NONRECOURSE DEBT SHARING. For purposes of this Agreement,
nonrecourse deductions, within the meaning of Regulation Section 1.704-2(b),
shall be allocated among the Partners Pro Rata. Solely for purposes of
determining a Partner's proportionate share of the "excess nonrecourse
liabilities" of the Partnership within the meaning of Regulation Section
1.752-3(a)(3), Partnership Profits are allocated to the Partners Pro Rata.

         4.5 FEDERAL TAX ALLOCATIONS.

         (a) GENERAL RULE. Except as otherwise provided in the following
paragraphs of this Section 4.5, allocations for federal income tax purposes of
items of income, gain, loss and deduction, and credits and basis therefor, shall
be made in the same manner as book allocations are made.

         (b) SPECIAL ALLOCATIONS. Except as provided in Section 4.5(c),
depreciation and other amortization with respect to each Partnership asset
acquired pursuant to Section 6.7(iv) shall be allocated to each Partner in
accordance with its contribution to the adjusted tax basis of such asset.

         (c) ELIMINATION OF BOOK/TAX DISPARITIES. Taxable income and tax
deductions shall be shared among the Partners so as to take into account the
variation between the Book Value and the adjusted tax basis of each property at
the time it is contributed to the Partnership and at each time it is revalued.

                  (i) To account for such variation, effective as of the
         formation of the Partnership:

                           (A) the depreciation and other deductions
                  attributable to the basis that the contributing Partner had in
                  each property at the time of contribution shall be allocated
                  to such Partner, and

                           (B) upon disposition of a contributed property, the
                  excess of its Book Value at the time of such disposition over
                  its tax basis at the time of such disposition shall be
                  allocated to the Partner who contributed the property.

                  (ii) If the Book Value of a Partnership property is revalued
         as of a date subsequent to the date of its acquisition by the
         Partnership, the portion of its Book Value at the time of its
         disposition that is attributable to the increase resulting from such
         revaluation:

                           (A) shall be disregarded in applying Section
                  4.5(c)(i)(B) to the Partner who contributed such property, and

                                       8
<PAGE>   14

                           (B) shall be treated for purposes of this Section
                  4.5(c) as a separate property that was contributed on the
                  revaluation date by the Persons who were partners immediately
                  prior to the revaluation date.

                  (iii) The Partners agree that the foregoing allocations
         constitute a reasonable method for purposes of Regulation Section
         1.704-3(a)(1) and will be so reported and defended by the Partnership
         and all Partners unless and until the Partners otherwise agree or it is
         otherwise Finally Determined.

         (d) ALLOCATION OF ITEMS AMONG PARTNERS. Each item of income, gain,
loss, deduction and credit and all other items governed by section 702(a) of the
Code shall be allocated among the Partners in proportion to the allocation of
Profits, Losses and other items to such Partners hereunder, PROVIDED that any
gain treated as ordinary income because it is attributable to the recapture of
any depreciation or amortization shall be allocated among the Partners in
accordance with Regulation Section 1.1245-1(e)(2) and Section 1.1250-l(f).

         (e) SECTION 754 ELECTION ALLOCATIONS. Income and deductions of the
Partnership that are attributable to the election under section 754 of the Code
shall be allocated to the Partners entitled thereto.

         4.6 OTHER TAX ALLOCATIONS. Items of income, gain, loss, deduction,
credit and tax preference for state, local and foreign income tax purposes shall
be allocated among the Partners in a manner consistent with the allocation of
such items for federal income tax purposes in accordance with the foregoing
provisions of this Section.

         4.7 TRANSACTION COSTS. If the Partnership is entitled to deductions
with respect to costs described in Section 6.10 of the Master Transaction
Agreement that have been incurred by a Partner and for which that Partner is not
entitled to reimbursement, such deductions shall be allocated to that Partner.

                ACCOUNTING, FINANCIAL REPORTING AND TAX MATTERS

         5.1 FISCAL YEAR. The fiscal year of the Partnership shall be the
calendar year.

         5.2 METHOD OF ACCOUNTING FOR FINANCIAL REPORTING PURPOSES. For
financial reporting purposes, the Partnership shall adopt a standard set of
accounting policies and shall maintain separate books of account, all in
accordance with GAAP. The Partnership's financial reports shall comply with
requirements of the SEC to the extent applicable to the Partnership and any
Partner or any controlling Person of such Partner, to the extent such
information is necessary, in conjunction with the financial reporting
obligations of such Person under applicable SEC requirements.

<PAGE>   15

         5.3 BOOKS AND RECORDS; RIGHT OF PARTNERS TO AUDIT.

         (a) Proper and complete records and books of account of the
Partnership's business, including all such transactions and other matters as are
usually entered into records and books of account maintained by businesses of
like character or as are required by law, shall be kept by the Partnership at
the Partnership's principal place of business. The Partnership shall maintain
one or more bank accounts in a manner so that the amount of such funds can at
all times be determined.

         (b) Each Partner and its internal and independent auditors, at the
expense of such Partner, shall have full and complete access to the internal and
independent auditors of the Partnership and shall have the right to inspect all
books and records and the physical properties of the Partnership during normal
business hours and, at its own expense, to cause an independent audit thereof.
The Partnership shall make all books and records of the Partnership available to
such Partner and its internal and independent auditors in connection with such
audit and shall cooperate with such Partner and auditors and to provide any
assistance reasonably necessary in connection with such audit.

         (c) The Partnership will cause an independent audit to be conducted
annually, and the independent auditors for the Partnership shall be Arthur
Andersen L.L.P. unless and until changed by the Partnership Governance
Committee.

         5.5 METHOD OF ACCOUNTING FOR BOOK AND TAX PURPOSES. For purposes of
making allocations and distributions hereunder (including distributions in
liquidation of the Partnership in accordance with Capital Account balances as
required by Section 12.2), Capital Accounts and Profits and Losses and other
items described in Section 4.1 shall be determined in accordance with federal
income tax accounting principles utilizing the accrual method of accounting,
with the adjustments required by Regulation Section 1.704-l(b) to properly
maintain Capital Accounts.

         5.6 TAXATION.

         (a) STATUS OF THE PARTNERSHIP. The Partners acknowledge that the

                  appropriate, with the determination of whether an election is
                  appropriate to be made pursuant to the principle that each
                  Partner shall be treated equally (i.e., no Partner will

<PAGE>   17

         (c) TAX RETURNS. The Tax Matters Partner, on behalf of the Partnership,
shall prepare and file the necessary tax and information returns. Each Partner
shall timely provide such information, if any, as may be needed by the
Partnership for purposes of preparing such tax and information returns. At least
90 days before the due date (as extended) for the Partnership's federal income
tax return, the Tax Matters Partner shall deliver a draft of such return to each
Partner. Each Partner shall have 15 days after receipt of the draft in which to
furnish any objections or comments on the draft to the Tax Matters Partner. The
Tax Matters Partner shall use commercially reasonable efforts to finalize the
Partnership's federal income tax return at least 60 days before the due date for
filing (as extended) of such return. A Partner may not report its share of any
Partnership tax item in a manner inconsistent with the Partnership's reporting
of such item unless the Partner has timely furnished its objection to the Tax
Matters Partner as provided in the second preceding sentence. If a Partner
reports its share of any Partnership tax item in a manner inconsistent with the
Partnership's reporting of such item, such Partner shall promptly notify the
Partnership in writing at least 20 Business Days prior to the filing of any
statement with the IRS in which such inconsistent position is reported. The
Partnership shall promptly deliver to each Partner a copy of the federal income
tax return for the Partnership as filed with the appropriate taxing authorities
and a copy of any material state and local income tax return as filed.

         (d) TAX AUDITS.

                  (i) FEDERAL TAX MATTERS. The Partnership is authorized to make
         such filings with the IRS as may be required to designate OCC LP in its
         capacity as the sole owner of OCC GP as the Tax Matters Partner. The
         Tax Matters Partner, as an authorized representative of the
         Partnership, shall direct the defense of any claims made by the IRS to
         the extent that such claims relate to the adjustment of Partnership
         items at the Partnership level. The Tax Matters Partner shall promptly
         deliver to each Partner a copy of all notices, communications, reports
         or writings of any kind (including any notice of beginning of
         administrative proceedings or any report explaining the reasons for a
         proposed adjustment) received from the IRS relating to or potentially
         resulting in an adjustment of Partnership items, as well as any other
         information requested by a Partner that is commercially reasonable to
         request. The Tax Matters Partner shall act in good faith in deciding
         whether to contest at the administrative and judicial level any
         proposed adjustment of a Partnership item and whether to appeal any
         adverse judicial decision. The Tax Matters Partner shall keep each
         Partner advised of all material developments with respect to any
         proposed adjustment that comes to its attention. All costs incurred by
         the Tax Matters Partner in performing under this subsection (d) shall
         be paid by the Partnership. The Tax Matters Partner shall have sole
         authority to represent the Partnership in connection with all tax
         audits, including the power to extend the statute of limitations, to
         enter in any settlement, and to litigate any proposed partnership
         adjustment, subject to the following: (A) No settlement will be entered
         into with respect to an item that would materially affect any Partner
         adversely unless each Partner is first notified of the terms of the
         settlement; and no Partner will be bound by any settlement unless it
         consents thereto; (B) If a Partner does not consent to a settlement,
         the settlement will nevertheless be binding on all Partners who do
         consent; and the non-consenting Partner may, at its sole cost, pursue
 
                                       12
<PAGE>   18

         such administrative or judicial remedies as it deems appropriate; (C)
         If the Tax Matters Partner brings an action in any court, each Partner,
         at its sole cost, shall have the right to intervene in the proceeding
         to the extent permitted by the court; and (D) The Tax Matters Partner
         shall take any and all actions as may be necessary to cause Geon LP to
         become a partner required to be notified pursuant to section 6223 of
         the Code or a similar provision under any state law.

                  (ii) STATE AND LOCAL TAX MATTERS. The Partnership shall
         promptly deliver to each Partner a copy of all notices, communications,
         reports or writings of any kind with respect to income or similar taxes
         received from any state or local taxing authority relating to the
         Partnership that might, in the judgment of the Tax Matters Partner,
         materially and adversely affect any Partner, and shall keep each
         Partner advised of all material developments with respect to any
         proposed adjustment of Partnership items that come to its attention.

                  (iii) CONTINUATION OF RIGHTS. Each Partner shall continue to
         have the rights described in this Section 5.6(d) with respect to tax
         matters relating to any period during which it was a Partner, whether
         or not it is a Partner at the time of the tax audit or contest.

         (e) TAX RULINGS. No Person other than the Tax Matters Partner shall
request an administrative ruling (or similar administrative procedures) from any
taxing authority with respect to any tax issue relating to the Partnership or
affecting the taxation of any other Partner unless such Person shall have
received written authorization from the Tax Matters Partner and any such other
Partner to make such request.

         (f) TAX INFORMATION. At the request of any Partner, the Tax Matters
Partner shall timely furnish annual earnings and profits computations (as
defined in section 312 of the Code) with respect to that Partner's share of
Partnership income.

         5.7 DELEGATION. The Partners agree that all of the tasks to be
performed under this Section (other than serving as Tax Matters Partner) may be
delegated to employees and consultants of the Partnership.


                                    SECTION 6
                                   MANAGEMENT
                                   ----------

         6.1 PARTNERSHIP GOVERNANCE COMMITTEE.

         (a) The General Partner and Geon LP hereby establish a committee (the
"Partnership Governance Committee") to manage and control the business, property
and affairs of the Partnership, including the determination and implementation
of the Partnership's strategic direction. The Partnership Governance Committee
(on behalf of the Partners) shall have (i) the full authority of the Partners to
exercise all of the powers of the Partnership and (ii) full control over the
business, property and affairs of the Partnership. Except to the extent set
forth in this Agreement, the 

                                       13
<PAGE>   19

Partnership Governance Committee shall have full, exclusive and complete
discretion to manage and control the business, property and affairs of the
Partnership, to make all decisions affecting the business, property and affairs
of the Partnership and to take all such actions as it deems necessary and
appropriate to accomplish the purpose of the Partnership as set forth in Section
1.4 (as such purpose may be expanded in accordance with Section 6.7(i)).

         (b) The Partnership Governance Committee shall act exclusively by means
of Partnership Governance Committee Action. As used in this Agreement,
"Partnership Governance Committee Action" means any action that the Partnership
Governance Committee is authorized and empowered to take in accordance with this
Agreement and the Act and that is taken by the Partnership Governance Committee
either (i) by action taken at a meeting of the Partnership Governance Committee
duly called and held in accordance with this Agreement or (ii) by a formal
written consent complying with the requirements of Section 6.5(f). In no event
shall the Partnership Governance Committee be authorized to act other than by
Partnership Governance Committee Action, and any action or purported action by
the Partnership Governance Committee (including any authorization, consent,
approval, waiver, decision or vote) not constituting a Partnership Governance
Committee Action shall be null and void and of no force and effect. Each
Partnership Governance Committee Action shall be binding on the Partnership.

         (c) The Partnership Governance Committee shall adopt policies and
procedures consistent with this Agreement (including Section 6.7) or the Act,
governing financial controls and legal compliance, including delegations of
authority (and limitations thereon) to the officers of the Partnership as
permitted hereby. Such policies and procedures may be revised or revoked (in a
manner consistent with this Agreement and the Act) from time to time as
determined by the Partnership Governance Committee. To the extent any authority
is not delegated to officers of the Partnership in this Agreement or in
accordance with Partnership Governance Committee Action, it shall remain with
the Partnership Governance Committee.

         6.2 LIMITATIONS ON AUTHORITY. Except as expressly set forth in this
Agreement, each of the General Partner and Geon LP agrees to exercise its
authority to manage and control the Partnership only through the Partnership
Governance Committee. Each of the General Partner and Geon LP agrees not to
exercise, or purport or attempt to exercise any authority (i) to act for or
incur, create or assume any obligation, liability or responsibility on behalf of
the Partnership or any other Partner, (ii) to execute any documents on behalf
of, or otherwise bind, or purport or attempt to bind, the Partnership or (iii)
to otherwise transact any business in the Partnership's name, in each case
except pursuant to Partnership Governance Committee Action.

         6.3 LACK OF AUTHORITY. Except as expressly set forth in this Agreement,
no Person or Persons other than (i) the General Partner and Geon LP, acting
through the Partnership Governance Committee, and (ii) the officers of the
Partnership appointed in accordance with this Agreement and acting as agents or
employees, as applicable, of the Partnership in conformity with this Agreement
and any applicable Partnership Governance Committee Action, shall be authorized
(a) to exercise 

                                       14
<PAGE>   20

the powers of the Partnership, (b) to manage the business, property and affairs
of the Partnership or (c) to contract for, or incur on behalf of, the
Partnership any debts, liabilities or other obligations.

         6.4 COMPOSITION OF PARTNERSHIP GOVERNANCE COMMITTEE.

         (a) The Partnership Governance Committee shall consist of six
Representatives, with the General Partner designating three Representatives and
Geon LP designating three Representatives (each a "Representative"). All the
Representatives of both the General Partner and Geon LP shall together
constitute the Partnership Governance Committee.

         (b) The General Partner and Geon LP may designate one or more
individuals (each an "Alternate") who (i) shall be authorized, in the event a
Representative is absent from any meeting of the Partnership Governance
Committee (and in the order of succession designated by either the General
Partner or Geon LP, as applicable), to attend such meeting in the place of, and
as substitute for, such Representative and (ii) shall be vested with all the
powers to take action on behalf of either the General Partner or Geon LP, as
applicable, that the absent Representative could have exercised at such meeting.
The term "Representative," when used herein with reference to any Representative
who is absent from a meeting of the Partnership Governance Committee, shall mean
and refer to any Alternate attending such meeting in place of such absent
Representative.

         (c) On or before the date hereof, the General Partner and Geon LP shall
have delivered to the other a written notice (i) designating the three persons
to serve as such Partner's initial Representatives and (ii) designating the
person or persons, if any, who are to serve as initial Alternates and their
order of succession.

         (d) Each of the General Partner and Geon LP may, in its sole discretion
and by written notice delivered to the other and the Partnership at any time or
from time to time, remove or replace one or more of its Representatives or
change one or more of its Alternates. If a Representative or Alternate dies,
resigns or becomes disabled or incapacitated, the Partner, whether the General
Partner or Geon LP, that designated such Representative or Alternate, as the
case may be, shall promptly designate a replacement. Each Representative and
each Alternate shall serve until replaced by the Partner that designated such
Representative or Alternate, as the case may be.

         (e) Copies of all written notices designating Representatives and
Alternates shall be delivered to the Secretary and shall be placed in the
Partnership minute books, but the failure to deliver a copy of any such notice
to the Secretary shall not affect the validity or effectiveness of such notice
or the designation described therein.

         (f) Each Representative, in his capacity as such, shall be the agent of
the Partner that designated such Representative. Accordingly, (i) each
Representative, as such, shall act (or refrain from acting) with respect to the
business, property and affairs of the Partnership solely in accordance with the
wishes of the Partner that designated such Representative and (ii) no
Representative, as such, shall owe (or be deemed to owe) any duty (fiduciary or
otherwise) to the Partnership or to any 

                                       15
<PAGE>   21

Partner other than the Partner that designated such Representative; PROVIDED,
HOWEVER, that nothing in this Agreement is intended to or shall relieve or
discharge any Representative or Partner from liability to the Partnership or the
Partners on account of any fraudulent or intentional misconduct of such
Representative. Nothing in this Section 6.4(f) shall limit the duty owed to the
Partnership by any person acting in his capacity as an officer of the
Partnership (including any such officer who is also a Representative).

         (g) Representatives shall not receive from the Partnership any
compensation for their service or any reimbursement of expenses for attendance
at meetings of the Partnership Governance Committee.

         6.5 PARTNERSHIP GOVERNANCE COMMITTEE MEETINGS.

         (a) Regular but not less often than quarterly meetings of the
Partnership Governance Committee shall be held at such times and at such places
as shall from time to time be determined in advance and committed to a written
schedule by the Partnership Governance Committee. The first regular meeting of
the Partnership Governance Committee during each fiscal year shall be deemed to
be the "Annual Meeting." The Secretary shall deliver by commercial courier
service or other hand delivery or transmit by facsimile transmission (with proof
of confirmation from the transmitting machine), an agenda for each regular
meeting to the Representatives at least five Business Days prior to such
meeting. Each agenda for a regular meeting shall specify, to a reasonable
degree, the business to be transacted at such meeting. Subject to Section 6.6,
at any regular meeting of the Partnership Governance Committee at which a quorum
is present, any and all business of the Partnership may be transacted.

         (b) Special meetings of the Partnership Governance Committee may be
called by any Representative by delivering by commercial courier service or
other hand delivery or transmitting by facsimile transmission (with proof of
confirmation from the transmitting machine), written notice of a special meeting
to each of the other Representatives at least two Business Days before such
meeting. Each notice of a special meeting shall specify, to a reasonable degree,
the business to be transacted at, or the purpose of, such meeting. Notice of any
special meeting may be waived before or after the meeting by a written waiver of
notice signed by the Representative entitled to notice. A Representative's
attendance at a special meeting shall constitute a waiver of notice unless the
Representative states at the beginning of the meeting his objection to the
transaction of business because the meeting was not lawfully called or convened.
Special meetings of the Partnership Governance Committee shall be held at the
Partnership's offices (or at such other place or in such other manner as the
Representatives shall agree) at such time as may be stated in the notice of such
meeting.

         (c) One Representative of each of the General Partner and Geon LP shall
serve as a co-chair of each meeting (regular and special) of the Partnership
Governance Committee. Either co-chair may instruct the Secretary to include one
or more items on a meeting agenda and neither co-chair nor the Secretary may
delete or exclude an agenda item proposed by the other. 


                                       16
<PAGE>   22


         (d) Following each meeting of the Partnership Governance Committee, the
Secretary shall promptly draft and distribute minutes of such meeting to the
Representatives for approval at the next meeting, and after such approval shall
retain the minutes in the Partnership minute books.

         (e) Representatives, at their discretion, may participate in or hold
regular or special meetings of the Partnership Governance Committee by means of
a telephone conference or any at least equally effective device or technology by
which all individuals participating in the meeting may hear each other, and
participation in such a meeting shall constitute presence in person at such
meeting.

         (f) Any action required or permitted to be taken at a meeting of the
Partnership Governance Committee may be taken without a meeting if a consent in
writing, setting forth the action so taken, shall be signed by at least two
Representatives of each of the General Partner and Geon LP, and such consent
shall have the same force and effect as a duly conducted vote of the Partnership
Governance Committee. A counterpart of each such consent to action shall be
delivered promptly to each of the Representatives and to the Secretary for
placement in the minute books of the Partnership, but the failure to deliver a
counterpart of any such consent to action to the Secretary shall not affect the
validity or effectiveness of such consent to action.

         6.6 PARTNERSHIP GOVERNANCE COMMITTEE QUORUM AND GENERAL VOTING
REQUIREMENT.

         (a) The presence of at least two Representatives (including any duly
present Alternates) of the General Partner shall constitute a quorum of the
Partnership Governance Committee for the transaction of business and the taking
of appropriate Partnership Governance Committee Actions at any meeting;
PROVIDED, HOWEVER, that the presence at such meeting of at least two
Representatives (including any duly present Alternates) from each of the General
Partner and Geon LP shall be necessary for the taking of any action described in
Section 6.7; and PROVIDED, FURTHER, that no Partnership Governance Committee
Actions can be taken at any meeting with respect to any matter that was not
reflected, with a reasonable level of specificity, on an agenda for such meeting
that was delivered in accordance with Section 6.5 unless at least one
Representative of each of the General Partner and Geon LP is present. No
Partnership Governance Committee Action may be taken at any meeting at which a
quorum is not present.

         (b) Except as otherwise provided in Section 6.7 or elsewhere in this
Agreement, the approval of two or more Representatives acting for the General
Partner will be sufficient for the Partnership Governance Committee to take any
Partnership Governance Committee Action and in such case the Partnership shall
be authorized to take such action without the consent of any other Person.

         6.7 PARTNERSHIP GOVERNANCE COMMITTEE UNANIMOUS VOTING REQUIREMENTS.
Unless and until two or more Representatives of the General Partner and two or
more Representatives of Geon LP have given their approval (in which event a
Partnership Governance Committee Action is hereby authorized without the need
for the consent of any other Person), no Partnership Governance 

                                       17
<PAGE>   23


Committee Action will be deemed for any purpose to have been taken at any
Partnership Governance Committee meeting that would cause or permit the
Partnership or any subsidiary thereof (or any Person acting in the name or on
behalf of any of them) directly or indirectly to take (or commit to take), and
neither the Partnership nor any subsidiary thereof nor any person acting in the
name or on behalf of any of them directly or indirectly may take or commit to
take, any of the actions described below (whether in a single transaction or
series of related transactions):

                  (i) to cause the Partnership, directly or indirectly, to
         engage, participate or invest in any business outside the scope of its
         business as described in Section 1.4;

                  (ii) to approve any Strategic Plan, as well as any amendments
         or updates thereto (including the annual updates provided for in
         Section 8.1);

                  (iii) except as contemplated by Section 12.2, to authorize any
         disposition of assets outside the ordinary course of business having a
         fair market value exceeding $50 million in any one transaction or a
         series of related transactions not contemplated in an approved
         Strategic Plan; PROVIDED, HOWEVER, that no such approval shall be
         required in respect of a disposition of assets in excess of such
         threshold amount if the CEO, acting through the Partnership Governance
         Committee, shall obtain an opinion, in form and substance reasonably
         satisfactory to the representatives of both the General Partner and
         Geon LP, from a nationally recognized independent professional
         appraisal firm with a recognized expertise in process chemical plants,
         as to the fairness and adequacy of the consideration received by the
         Partnership for such assets, taking into consideration all of the terms
         of such disposition; PROVIDED, FURTHER, HOWEVER, that in no event shall
         a disposition of assets in excess of such threshold amount be made to
         an Affiliate of the General Partner or Geon LP;

                  (iv) to authorize any acquisition of assets outside the
         ordinary course of business or any capital expenditure exceeding $25
         million that is not contemplated in an approved Strategic Plan;
         PROVIDED, HOWEVER, that, if the Representatives of Geon LP do not
         approve an acquisition of assets or a capital expenditure exceeding $25
         million that is not contemplated in an approved Strategic Plan or Geon
         LP does not agree to pay its Pro Rata share of any additional capital
         contribution required to effect such acquisition or capital
         expenditure, approval of the Representatives of Geon LP is not required
         for the Partnership Governance Committee to authorize such acquisition
         or capital expenditure if all amounts for such acquisition or
         expenditure that exceed $1 million are paid, directly or indirectly, by
         OCC GP and OCC LP, and in such an event, (a) all such amounts paid by
         OCC GP and OCC LP shall be deemed additional capital contributions to
         the Partnership, and (b) OCC GP and OCC LP shall receive additional
         Units to account for such additional capital contributions. The number
         of additional Units received by such contributing Partners shall,
         immediately after being issued, constitute a percentage of all then
         outstanding Units equal to the following, expressed as a percentage:
         A/B, where A = the Enterprise Value Increase; and B = the Enterprise
         Value Increase plus the Partnership Annual Agreed Value for the year
         during which such acquisition or expenditure is made;

                  (v) to require capital contributions to the Partnership (other
         than contributions contemplated by the Asset Contribution Agreements or
         an approved Strategic Plan or to achieve or maintain compliance with
         any HSE Law or other law) within any fiscal year (a) if the total of
         such contributions required from the Partners within that year would
         exceed $10 million or (b) to the extent the aggregate principal amount
         of the Partnership's borrowings is less than the Leverage Ceiling;

                  (vi) to make borrowings under one or more of the Partnership's
         bank credit facilities, its uncommitted lines of credit or any credit
         facility or debt instrument of the Partnership of any kind that
         finances or refinances all or any portion of the Partnership's credit
         facilities, or to enter into any capitalized lease or similar
         off-balance sheet financing arrangement, at any time, if as a result of
         any such borrowing the aggregate principal amount of all such
         borrowings outstanding at such time would exceed $575 million (the
         "Leverage Ceiling");

                  (vii) to enter into interest rate protection or other hedging
         agreements, including commodity hedging agreements, unless the

         such term is defined in the Financial Accounting Standards Board
         Statement of Financial Accounting Standards Number 80 and Number 133
         (other than commodity hedging agreements offset by physical positions

         Units or other equity securities);

                  (ix) except as contemplated by Section 12.2, to make

         (a) From time to time, the Partnership Governance Committee may, by
Partnership Governance Committee Action, designate one or more committees
("Auxiliary Committees") or disband any Auxiliary Committee. Each Auxiliary
Committee shall (i) operate under the specific authority delegated to it by the

of assisting the Partnership Governance Committee in managing (on behalf of the
General Partners) the business, property and affairs of the Partnership and (ii)
report to the Partnership Governance Committee.

         (b) Each of the General Partner and Geon LP shall have the right to

exchange of all or substantially all of the property and assets of the
Partnership, authorizing a dissolution of the Partnership or declaring a

The members of any Auxiliary Committee, at their discretion, may participate in

constitute presence in person at such meeting.

         6.9 ENTERPRISE VALUE INCREASE AND PARTNERSHIP ANNUAL AGREED VALUE. The

calendar year and applying for the entire calendar year in which such value is
determined; PROVIDED, HOWEVER, that (i) the Partnership Annual Agreed Value
shall be $2 billion for 1999 and 2000, and (ii) if the General Partner and Geon
LP are unable to agree on a Partnership Annual Agreed Value by January 31 of any
year in which such determination is necessary, then the Partnership Annual
Agreed Value for that year shall be the same as the Partnership Annual Agreed
Value for the immediately preceding year. The setting of the initial Partnership
Annual Agreed Value at $2 billion is solely for the purposes of the calculation
under Section 6.7(iv) and is not intended necessarily to reflect or bear upon
the determination of the Fair Market Value of the Partnership.

                             OFFICERS AND EMPLOYEES

         7.1 PARTNERSHIP OFFICERS.

         (a) The Partnership Governance Committee may select natural persons who
are (or upon becoming an officer will be) agents or employees of the Partnership
to be designated as officers of the Partnership, with such titles as the
Partnership Governance Committee shall determine. The Partnership Governance
Committee also shall appoint a Secretary and may appoint such other officers and

provided in this Agreement or as may be determined by Partnership Governance
Committee Action.

Executive Officer ("CEO"), and others as determined from time to time by
Partnership Governance Committee Action (collectively, the "Executive
Officers").

<PAGE>   27

         (c) The Partnership Governance Committee may leave unfilled any offices
except those of CEO and Secretary. Two or more offices may be held by the same
person, except that the same person may not hold the offices of CEO and
Secretary.

         7.2 SELECTION AND TERM OF EXECUTIVE OFFICERS.

         (a) The initial Executive Officers are listed on Appendix C.

         (b) The CEO shall hold office for a three-year term, subject to the
CEO's earlier death, resignation or removal. Upon the expiration of such term or
earlier death, resignation or removal, OCC GP shall designate the replacement
CEO. The CEO shall not be required to be an employee of the Partnership but
shall be required to devote substantially all of his or her efforts to the
Partnership's business.

         (c) Each Executive Officer (other than the CEO) shall hold office until
his or her death, resignation or removal. Upon the death, resignation or removal
of an Executive Officer, or the creation of a new Executive Officer position,
the CEO may nominate a person to fill the vacancy, which shall be subject to
Partnership Governance Committee approval. Executive Officers shall not be
required to be employees of the Partnership. Any Executive Officer also may
serve as an officer or employee of any Partner or Affiliate of a Partner.

         7.3 REMOVAL OF EXECUTIVE OFFICERS.

         (a) The CEO may be removed (i) at any time, by Partnership Governance
Committee Action taken pursuant to Section 6.6, with or without cause, whenever
in the judgment of the Partnership Governance Committee the best interests of
the Partnership would be served thereby or (ii) by Geon LP, at any time after
twelve months have passed following the delivery of written notice from Geon LP
to the Partnership Governance Committee stating that the CEO should be removed
for cause and setting forth with reasonable specificity the factual bases for
such removal, if the bases for such removal for cause have not been rescinded,
removed or cured (to the reasonable satisfaction of Geon LP) within such twelve
month period.

         (b) Any Executive Officer (other than the CEO), or any other officer or
agent may be removed, at any time, by Partnership Governance Committee Action
taken pursuant to Section 6.6, with or without cause, upon the recommendation of
the CEO, whenever in the judgment of the Partnership Governance Committee the
best interests of the Partnership would be served thereby.

         (c) Notwithstanding anything to the contrary in Sections 7.3(a) and
7.3(b), either of the General Partner or Geon LP may, by action of two or more
of its Representatives, remove from office any Executive Officer who takes or
causes the Partnership to take any action described in Section 6.7 that has not
been approved by two or more Representatives of the General Partner and two or
more Representatives of Geon LP as contemplated by Section 6.7. Any such removal
shall be effected by delivery by such Representatives of written notice of such
removal (i) to such 

                                       22
<PAGE>   28


Executive Officer and (ii) to the Representatives of the other Partner; PROVIDED
THAT such removal shall not be effective if such action is rescinded or cured
(to the reasonable satisfaction of the Partner, whether the General Partner or
Geon LP, who has delivered such notice) promptly after such notice is delivered.

         7.4 DUTIES.

         (a) Each officer or employee of the Partnership shall owe to the
Partnership, but not to any Partner, all such duties (fiduciary or otherwise) as
are imposed upon such an officer or employee of a Delaware corporation. Without
limitation of the foregoing, each officer and employee in any dealings with a
Partner shall have a duty to act in good faith and to deal fairly; PROVIDED,
THAT, no officer shall be liable to the Partnership or to any Partner for his or
her good faith reliance on the provisions of this Agreement. Notwithstanding the
foregoing, it is understood that any officer or employee of the Partnership who
is also a Representative of either the General Partner or Geon LP shall, in his
capacity as a Representative, owe no duty (fiduciary or otherwise) to any Person
other than such Representative's appointing Partner.

         (b) The policies and procedures of the Partnership adopted by the
Partnership Governance Committee may set forth the powers and duties of the
officers of the Partnership to the extent not set forth in or inconsistent with
this Agreement. The officers of the Partnership shall have such powers and
duties, except as modified by the Partnership Governance Committee, as generally
pertain to their respective offices in the case of a publicly held Delaware
corporation, as well as other such powers and duties as from time to time may be
conferred by the Partnership Governance Committee and by this Agreement. The CEO
and the other officers and employees of the Partnership shall develop and
implement management and other policies and procedures consistent with this
Agreement and the general policies and procedures established by the Partnership
Governance Committee.

         (c) Notwithstanding any other provision of this Agreement, no Partner,
Representative, officer, employee or agent of the Partnership shall have the
power or authority, without specific authorization from the Partnership
Governance Committee, to undertake any of the following:

         (i)      to do any act which contravenes (or otherwise is inconsistent
                  with) this Agreement or which would make it impracticable or
                  impossible to carry on the Partnership's business;

         (ii)     to confess a judgment against the Partnership;

         (iii)    to possess Partnership property other than in the ordinary
                  conduct of the Partnership's business; or

         (iv)     to take, or cause to be taken, any of the actions described in
                  Section 6.7.

<PAGE>   29

         7.5 CEO. Subject to the terms of this Agreement, the CEO shall have
general authority and discretion comparable to that of a chief executive officer
of a publicly held Delaware corporation of similar size to direct and control
the business and affairs of the Partnership, including its day-to-day operations
in a manner consistent with the Annual Budget and the most recently approved
Strategic Plan. The Partnership Governance Committee shall establish and
maintain a compensation plan for the CEO and the other key employees of the
Partnership. The level of compensation provided in such plan for the CEO and the
other key employees of the Partnership shall be consistent with levels obtaining
in the industry generally for comparably situated persons, and such plan shall
establish incentive compensation goals intended to reward the CEO and the other
key employees of the Partnership for achievement of the synergies and objectives
set forth in the Strategic Plan. The CEO shall take steps to implement all
orders and resolutions of the Partnership Governance Committee or, as
applicable, any Auxiliary Committee. The CEO shall be authorized to execute and
deliver, in the name and on behalf of the Partnership, (i) contracts or other
instruments authorized by Partnership Governance Committee Action and (ii)
contracts or instruments in the usual and regular course of business (not
otherwise requiring Partnership Governance Committee Action), except in cases
when the execution and delivery thereof shall be expressly delegated by the
Partnership Governance Committee to some other officer or agent of the
Partnership, and, in general, shall perform all duties incident to the office of
CEO as well as such other duties as from time to time may be assigned to him or
her by the Partnership Governance Committee or as are prescribed by this
Agreement.

         7.6 OTHER OFFICERS. The President (if any) and the Vice Presidents (if
any) shall perform such duties as may, from time to time, be assigned to them by
the Partnership Governance Committee or by the CEO. In addition, at the request
of the CEO, or in the absence or disability of the CEO, the President (if any)
or any Vice President, in any order determined by the Partnership Governance
Committee, temporarily shall perform all (or if limited through the scope of the
delegation, some of) the duties of the CEO, and, when so acting, shall have all
the powers of, and be subject to all restrictions upon, the CEO.

         7.7 SECRETARY. The Secretary shall keep the minutes of all meetings
(and copies of written records of action taken without a meeting) of the
Partnership Governance Committee in minute books provided for such purpose and
shall see that all notices are duly given in accordance with the provisions of
this Agreement. The Secretary shall be the custodian of the records and of the
seal, if any. The Secretary shall have general charge of books and papers of the
Partnership as the Partnership Governance Committee may direct and, in general,
shall perform all duties and exercise all powers incident to the office of
Secretary and such other duties and powers as the Partnership Governance
Committee or the CEO from time to time may assign to or confer upon the
Secretary.

         7.8 SALARIES. Salaries or other compensation of the other Executive
Officers of the Partnership shall be established by the CEO consistent with
plans approved by the Partnership Governance Committee. Except as approved by
the Partnership Governance Committee, all fees and compensation of the officers
and employees of the Partnership other than the CEO with respect to their
services as such officers and employees shall be payable solely by the
Partnership and no 

                                       24
<PAGE>   30

Partner or its Affiliates shall pay (or offer to pay) any such fees or
compensation to any officer or employee, except to the extent that the
Partnership shall have agreed with a Partner or one of its Affiliates pursuant
to a separate agreement that a portion of the compensation of such officer or
employee shall be paid by such Partner or Affiliate.

         7.9 DELEGATION. The Partnership Governance Committee may delegate
temporarily the powers and duties of any officer of the Partnership, in case of
absence or for any other reason, to any other officer of the Partnership, and
may authorize the delegation by any officer of the Partnership of any of such
officer's powers and duties to any other officer or employee of the Partnership,
subject to the general supervision of such officer.

         7.10 GENERAL AUTHORITY. Persons dealing with the Partnership are
entitled to rely conclusively on the power and authority of each of the officers
as set forth in this Agreement. In no event shall any Person dealing with any
officer with respect to any business or property of the Partnership be obligated
to ascertain that the terms of this Agreement have been complied with, or be
obligated to inquire into the necessity or expedience of any act or action of
the officer; and every contract, agreement, deed, mortgage, security agreement,
promissory note or other instrument or document executed by the officer with
respect to any business or property of the Partnership shall be conclusive
evidence in favor of any and every Person relying thereon or claiming thereunder
that (i) at the time of the execution and/or delivery thereof, this Agreement
was in full force and effect, (ii) the instrument or document was duly executed
in accordance with the terms and provisions of this Agreement and is binding
upon the Partnership, and (iii) the officer was duly authorized and empowered to
execute and deliver any and every such instrument or document for and on behalf
of the Partnership.


                                    SECTION 8
                   STRATEGIC PLANS, ANNUAL BUDGETS AND LOANS
                   -----------------------------------------

         8.1 STRATEGIC PLAN.

         (a) The Partnership shall be managed in accordance with a five-year
strategic business plan (the "Strategic Plan") that shall be updated annually
under the direction of the CEO and presented for approval by the Partnership
Governance Committee pursuant to Section 6.7 no later than 45 days prior to the
start of the first fiscal year covered by the updated plan.

         (b) The Strategic Plan shall establish the strategic direction of the
Partnership, including plans relating to capital maintenance and enhancement,
geographic expansion, acquisitions and dispositions, new product lines,
technology, long-term supply and customer arrangements, internal and external
financing, environmental and legal compliance, and plans, programs and policies
relating to compensation and industrial relations. Subject to Section 3.1, the
Strategic Plan also shall establish the Partnership's policies regarding the
timing and amount of any distributions to the Partners. The Strategic Plan shall
include projected income statements, balance sheets and cash flow statements,
including the expected timing and amounts of capital contributions and cash

                                       25
<PAGE>   31


distributions. The format and level of detail of each Strategic Plan shall be
consistent with that of the initial Strategic Plan agreed to by the Partners on
or prior to the Closing Date or the Strategic Plan most recently approved
pursuant to Section 6.7. Except for entering into the Related Agreements, the
Partnership shall not, on other than an arm's length basis, enter into, or waive
any material rights under, any agreement between the Partnership and a Partner
or its Affiliates unless the taking of such action is specifically contemplated
by an approved Strategic Plan.

         8.2 ANNUAL BUDGET.

         (a) The Executive Officers of the Partnership shall prepare an Annual
Budget (each, an "Annual Budget") for each fiscal year, including an Operating
Budget and Capital Expenditure Budget; PROVIDED that each Annual Budget shall be
consistent with the information for such fiscal year included in the Strategic
Plan most recently approved pursuant to Section 6.7; and PROVIDED, FURTHER, that
unless provided otherwise in the most recently approved Strategic Plan, the
Annual Budget (including any Annual Budget prepared under Section 8.2(b)) shall
utilize a format and provide a level of detail consistent with the Partnership's
initial Annual Budget. The Annual Budget for each year shall be submitted to the
Partnership Governance Committee for approval at least 45 days prior to the
start of the fiscal year covered by such budget. Each Annual Budget shall
incorporate (i) a projected income statement, balance sheet and a cash flow
statement, (ii) the amount of any corresponding cash deficiency or surplus and
(iii) the estimated amount, if any, and expected timing for all required capital
contributions. Each proposed Annual Budget shall be prepared on a basis
consistent with the Partnership's financial statements.

         (b) If for any fiscal year the Partnership Governance Committee has
failed to approve an updated Strategic Plan, then, subject to Section 8.5, for
such year and each subsequent year prior to approval of an updated Strategic
Plan, the Executive Officers of the Partnership shall prepare (and promptly
furnish to the Partnership Governance Committee) the Annual Budget consistent
with the projections and other information for that year included in the
Strategic Plan most recently approved pursuant to Section 6.7; PROVIDED,
HOWEVER, that the CEO, acting in good faith, shall be entitled to modify any
such Annual Budget in order to satisfy current contractual and compliance
obligations and to account for other changes in circumstances reflecting the
passage of time, such as general changes in general economic or industry
circumstances, or the occurrence of events beyond the control of the
Partnership, and notwithstanding any other provision of this Agreement, the CEO
shall be authorized to take or cause to be taken, on behalf of the Partnership,
all actions that the CEO determines in good faith are appropriate in order to
satisfy such obligations or respond to such changed circumstances. Except as may
be required above, the CEO shall not be authorized to cause the Partnership to
proceed with discretionary capital expenditures to accomplish capital
enhancement projects, except to the extent that such expenditures would enable
the Partnership to continue or complete any such capital project reflected in
the last Strategic Plan that was approved by the Partnership Governance
Committee pursuant to Section 6.7.

                                       26
<PAGE>   32

         (c) Each "Operating Budget" shall constitute an estimate for each
applicable period of all operating income, which shall include expenses required
to maintain, repair and restore to good and usable condition the Partnership's
assets.

         (d) Each "Capital Expenditure Budget" shall constitute an estimate for
the applicable period of the capital expenditures required to (i) accomplish
capital enhancement projects included in the most recently approved Strategic
Plan, (ii) maintain and preserve the Partnership's assets in good operating
condition and repair and (iii) achieve or maintain compliance with any HSE Law.

         8.3 FUNDING OF PARTNERSHIP EXPENSES. All Partnership expenses (both
operating and capital expenses), regardless of whether included in any Strategic
Plan or Annual Budget, shall be funded from operating cash flows or authorized
borrowings under available lines of credit, unless otherwise agreed bythe
Partnership Governance Committee. Subject to the limitations of Sections 2.3 and
6.7(v), if applicable, to the extent that the CEO determines at any time that
funds are needed to fund Partnership operations, the CEO may issue a Funding
Notice to the Limited Partners calling for an additional capital contribution.

         8.4 IMPLEMENTATION OF BUDGETS AND DISCRETIONARY EXPENDITURES BY CEO.

         (a) After a Strategic Plan and an Annual Budget have been approved by
the Partnership Governance Committee (or an Annual Budget has been developed in
accordance with Section 8.2(b)), the CEO will be authorized, without further
action by the Partnership Governance Committee, to cause the Partnership to make
expenditures consistent with such Strategic Plan and Annual Budget; PROVIDED,
HOWEVER, that all internal control policies and procedures, including those
regarding the required authority for certain expenditures, shall have been
followed.

         (b) In any emergency, the CEO or the CEO's designee shall be authorized
to take such actions and to make such expenditures as may be reasonably
necessary to react to the emergency, regardless of whether such expenditures
have been included in an approved Strategic Plan or Annual Budget. Promptly
after learning of an emergency, the CEO or such designee shall notify the
Representatives of the nature of the emergency and the response that has been
made, or is committed or proposed to be made, with respect to the emergency.

         8.5 STRATEGIC PLAN DEADLOCK. If, after the fifth anniversary of the
date of this Agreement, the Partnership Governance Committee has not agreed upon
and approved an updated Strategic Plan, as contemplated by Sections 6.7 and 8.1,
within 12 months after the beginning of the first fiscal year that would have
been covered by such plan, then the General Partner and Geon LP shall each
submit their disagreements to non-binding mediation by a Neutral. If the General
Partner and Geon LP are unable to agree upon a mutually acceptable Neutral
within 30 days after a nomination of a Neutral is made by the General Partner or
Geon LP to the other, then such Neutral shall upon the application of either the
General Partner or Geon LP be appointed within 70 days of such nomination by the
Center for Public Resources, or if such appointment is not so made promptly,
then promptly thereafter by the American Arbitration Association in Dallas,
Texas, or if such appointment is not 

                                       27
<PAGE>   33

so made promptly, then promptly thereafter by the senior United States District
Court judge sitting in Dallas, Texas. The fees of the Neutral shall be paid
equally by the General Partner and Geon LP. Within 20 days of selection of the
Neutral, two persons having decision-making authority on behalf of each the
General Partner and Geon LP shall meet with the Neutral and agree upon
procedures and a schedule for attempting to resolve the differences between the
General Partner and Geon LP. They shall continue to meet thereafter on a regular
basis until (i) agreement is reached by the General Partner and Geon LP (acting
through their Representatives) on an updated Strategic Plan or (ii) at least 24
months have elapsed since the beginning of the first fiscal year on or after the
fifth anniversary of the date of this Agreement that would have been covered by
the updated plan for which agreement was not reached, and the General Partner or
Geon LP shall determine and notify the other and the Neutral in writing (a
"Deadlock Notice") that no agreement resolving the dispute is likely to be
reached. Notwithstanding anything contained in this Agreement to the contrary,
in no event shall the General Partner or Geon LP have the right to commence the
procedures contained in this Section 8.5 until after the fifth anniversary of
the date of this Agreement.

         8.6 LOANS.

         (a) INITIAL FACILITIES. On the Closing Date, the Partnership shall
enter into the credit agreement provided for in Section 1.3(b)(x) of the Master
Transaction Agreement.

         (b) OTHER LOANS. The Partnership Governance Committee may by
Partnership Governance Committee Action authorize the CEO to cause the
Partnership to borrow funds from third party lenders. No Partner shall be
required, and the Partnership Governance Committee shall not be authorized to
require any Partner, to guarantee or to provide other credit or financial
support for any loan. Any Partner may, at its sole discretion, guarantee or
provide other credit or financial support for all or any portion of any debt of
the Partnership, for such period of time and on such other terms as the Partner
shall determine.


                                    SECTION 9
                               RIGHTS OF PARTNERS
                               ------------------

         9.1 DELEGATION AND CONTRACTS WITH RELATED PARTIES.

         (a) The Partners acknowledge that the General Partner and Geon LP
(acting through the Partnership Governance Committee) are permitted to delegate
responsibility for day-to-day operations of the Partnership to officers and
employees of the Partnership.

         (b) The Related Agreements, and upon receipt of any required approval
by the Partnership Governance Committee (including, as applicable, any approval
required by Section 6.7), all other contracts and transactions between the
Partnership and a Partner or its Affiliates, shall be deemed to be entered into
on an arm's-length basis and to be subject to ordinary contract and commercial
law, without any other duties or rights being implied by reason of the status of
being a Partner or by reason of any provision of this Agreement or the existence
of the Partnership. In the 

                                       28
<PAGE>   34

case of any contract (including applicable Related Agreements) between the
Partnership and OCC or any Affiliate thereof, Geon LP shall have the right under
all reasonable circumstances, after reasonable prior notice to the General
Partner, to cause the Partnership to exercise all of the Partnership's audit and
similar rights under any such contract, and shall have full access to any audit
or other reports resulting from the exercise of such rights.

         9.2 GENERAL AUTHORITY. Persons dealing with the Partnership are
entitled to rely conclusively on the power and authority of each of the General
Partner and Geon LP as set forth in this Agreement. In no event shall any Person
dealing with either the General Partner or Geon LP or such Partners'
representatives with respect to any business or property of the Partnership be
obligated to ascertain that the terms of this Agreement have been complied with,
or be obligated to inquire into the necessity or expedience of any act or action
of the General Partner or Geon LP or such Partners' representatives; and every
contract, agreement, deed, mortgage, security agreement, promissory note or
other instrument or document executed by the General Partner or Geon LP or such
Partners' representatives with respect to any business or property of the
Partnership shall be conclusive evidence in favor of any and every Person
relying thereon or claiming thereunder that (i) at the time of the execution
and/or delivery thereof, this Agreement was in full force and effect, (ii) the
instrument or document was duly executed in accordance with the terms and
provisions of this Agreement and is binding upon the Partnership, and (iii)
either the General Partner or Geon LP or such Partners' representative was duly
authorized and empowered to execute and deliver any and every such instrument or
document for and on behalf of the Partnership. Nothing in this Section 9.2 shall
be deemed to be a waiver or release of either the General Partner's or Geon LP's
obligations to the other Partners as set forth elsewhere in this Agreement.

         9.3 LIMITATION ON FIDUCIARY DUTY; NON-COMPETITION; RIGHT OF FIRST
OPPORTUNITY.

         (a) Each Partner (directly or through its Affiliates) is a
sophisticated party possessing extensive knowledge of and experience relating
to, and is actively engaged in, significant businesses in addition to its
Contributed Business, has been represented by legal counsel, is capable of
evaluating and has thoroughly considered the merits, risks and consequences of
the provisions of this Section 9.3 and is agreeing to such provision knowingly
and advisedly. The liability of the General Partner (including any liability of
its Affiliates or its and their respective officers, directors, agents and
employees) or of any Limited Partner (including any liability of its Affiliates
or its and their respective officers, agents, directors and employees), either
to the Partnership or to any other Partner, for any act or omission by such
Partner in its capacity as a partner of the Partnership that is imposed by such
Partner's status as a "general partner" or "limited partner" (as such terms are
used in the Act) of a limited partnership is hereby eliminated, waived and
limited to the fullest extent permitted by law; PROVIDED, HOWEVER, that the
General Partner and Geon LP shall at all times owe to the other a fiduciary duty
in observing the requirement described in Section 6.7 that (except as provided
in Section 6.7(iv)) two or more Representatives of the General Partner and two
or more Representatives of Geon LP shall be required to give their approval
before the Partnership may undertake any of the actions listed in Section 6.7.
Nothing in this Section 9.3(a) shall relieve any Partner from liability

                                       29
<PAGE>   35

for any breach of this Agreement, and the General Partner and Geon LP shall at
all times owe to each other a duty to act in good faith with respect to all
matters involving the Partnership.

         (b) Except as set forth in Section 9.3(c), each Partner's Affiliates
shall be free to engage in or possess an interest in any other business of any
type, including any business in direct competition with the Partnership, and to
avail itself of any business opportunity available to it without having to offer
the Partnership or any Partner the opportunity to participate in such business.
Except as set forth in Section 9.3(c), it is expressly agreed that the legal
doctrine of "corporate or business opportunities" sometimes applied to a Person
deemed to be subject to fiduciary or other similar duties so as to prevent such
Persons from engaging in or enjoying the benefits of certain additional business
opportunities shall not be applied in the case of any investment, acquisition,
business, activity or operation of any Partner's Affiliates.

         (c) (i) If a Partner's Affiliate desires to initiate or pursue an
opportunity to undertake, engage in, acquire or invest in a Related Business by
investing in or acquiring a Person whose business is a Related Business,
acquiring assets of a Related Business, or otherwise engaging in or undertaking
a Related Business (a "Business Opportunity"), such Affiliate (such Affiliate,
together with its Affiliates, being called the "Proposing Person") shall offer
the Partnership the Business Opportunity on the terms set forth in Section
9.3(c)(ii).

         (ii) When a Proposing Person offers a Business Opportunity to the
Partnership, the Partnership shall elect to do one of the following within a
reasonably prompt period:

         (A)      acquire or undertake the Business Opportunity for the benefit
                  of the Partnership as a whole, at the cost, expense and
                  benefit of the Partnership; provided, however, that, if the
                  Partnership ceases to actively pursue such opportunity for any
                  reason, then the Proposing Person will be entitled to proceed
                  under clause (B) below; or

         (B)      permit the Proposing Person to acquire or undertake the
                  Business Opportunity for its own benefit and account without
                  any duty to the Partnership or the other Partners with respect
                  thereto; PROVIDED, HOWEVER, that if the Business Opportunity
                  is in direct competition with the then existing business of
                  the Partnership (a "Competing Opportunity"), then the
                  Proposing Person and the Partnership shall, if either so
                  elects, promptly seek to negotiate and implement an
                  arrangement whereby the Partnership would either (i) acquire
                  or undertake the Competing Opportunity at the sole cost,
                  expense and benefit of the Proposing Person under a mutually
                  acceptable arrangement whereby the Competing Opportunity is
                  treated as a separate business within the Partnership with the
                  costs, expenses and benefits related thereto being borne and
                  enjoyed solely by the Proposing Person, or (ii) enter into a
                  management agreement with the Proposing Person to manage the
                  Competing Opportunity on behalf of the Proposing Person on
                  terms and conditions mutually acceptable to the Proposing
                  Person and the Partnership. If the Partnership and the
                  Proposing Person do not reach agreement as to such arrangement
                  within a reasonable period not to 

                                       30
<PAGE>   36

                  exceed 30 days, the Proposing Person may acquire or undertake
                  the Competing Opportunity for its own benefit and account
                  without any duty to the Partnership or the other Partners with
                  respect thereto.

         (d) Notwithstanding the provisions of Section 9.3(c)(ii), if the
Business Opportunity constitutes less than 25% (based on annual revenues of the
business to be acquired or invested in for the most recently completed fiscal
year) of an acquisition of or investment in assets, activities, operations or
businesses that is not otherwise a Related Business, then a Proposing Person may
acquire or invest in such Business Opportunity without first offering it to the
Partnership; PROVIDED, that, after completion of the acquisition or investment
thereof, such Proposing Person must offer the Business Opportunity to the
Partnership pursuant to the terms of Section 9.3(c)(ii); and if the Partnership
elects option (A) of Section 9.3(c)(ii) with respect thereto, the Business
Opportunity shall be acquired by the Partnership at its fair market value as
mutually agreed or Finally Determined as of the date of such acquisition.

         (e) If (i) the Partnership is presented with an opportunity to acquire
or undertake a Business Opportunity that it determines not to acquire or
undertake and (ii) the Representatives of the General Partner or Geon LP, but
not the other, desired that the Partnership acquire or undertake such Business
Opportunity, then the Partnership shall permit such first Partner's Affiliates
to acquire or undertake such Business Opportunity and Section 9.3(c)(ii)(B)
shall be deemed to be applicable thereto to the same extent as if such Partner's
Affiliates were a Proposing Person with respect to such Business Opportunity.

         9.4 LIMITED PARTNERS.

         (a) Except as expressly set forth in this Agreement, no Limited Partner
shall take part in the management or control of the Partnership's business,
transact any business in the Partnership's name or have the power to sign
documents for or otherwise to bind the Partnership.

         (b) Each Limited Partner shall have the rights with respect to the
Partnership's books and records as set forth in Section 5.3.

         9.5 PARTNER COVENANTS. Each Partner covenants and agrees with the
Partnership and with the other Partners as follows:

                  (i) It shall not exercise, or purport or attempt to exercise,
         its authority to withdraw, retire, resign, or assert that it has been
         expelled from the Partnership;

                  (ii) It shall not do any act that would make it impossible or
         impracticable to carry on the Partnership's business; and

                  (iii) It shall not act or purport or attempt to act in a
         manner inconsistent with any act of the General Partner or Geon LP
         acting pursuant to the Partnership Governance 

                                       31
<PAGE>   37

         Committee or in a manner contrary to the agreements of the Partners set
         forth in this Agreement;

PROVIDED, THAT, nothing in this Section 9.5 shall be deemed to waive its rights
under Sections 10, 11 or 12.

         9.6 SPECIAL PURPOSE ENTITIES. Each Partner covenants and agrees that
(i) its business shall be restricted solely to the holding of its Units and the
doing of things necessary or appropriate in connection therewith (including the
exercise of its rights and powers under this Agreement), and (ii) it shall not
own any assets, incur any liabilities or engage, participate or invest in any
business outside the scope of such business.



                                   SECTION 10
                             TRANSFERS AND PLEDGES
                             ---------------------

         10.1 RESTRICTIONS ON TRANSFER AND PROHIBITION ON PLEDGE. Except
pursuant to Section 11 or the procedures described below in this Section, a
Partner shall not, in any transaction or series of transactions, directly or
indirectly Transfer all or any part of its Units without the consent of the
Other Partner, which consent may be granted or withheld in the Other Partner's
sole discretion. A Partner shall not, in any transaction or series of
transactions, directly or indirectly Pledge all or any part of its Units or its
interest in the Partnership without the consent of the Other Partner, which
consent may be granted or withheld in the Other Partner's sole discretion.
Neither the term "Transfer" nor the term "Pledge," however, shall include an
assignment by a Partner of such Partner's right to receive distributions from
the Partnership so long as such assignment does not purport to assign any right
of such Partner to participate in or manage the affairs of the Partnership, to
receive any information or accounting of the affairs of the Partnership, or to
inspect the books or records of the Partnership or any other right of a Partner
pursuant to this Agreement or the Act. Any attempt by a Partner to Transfer or
Pledge all or a portion of its Units in violation of this Agreement shall be
void AB INITIO and shall not be effective to Transfer or Pledge such Units or 
any portion thereof. Subject to any applicable restrictions imposed by the
Parent Agreement, nothing in this Agreement shall prevent the Transfer or
Pledge by the owner thereof of any capital stock, equity ownership interests or
other securities of a Partner or any Affiliate of a Partner, whether such
Transfer or Pledge by such owner is in connection with the merger,
consolidation, conversion, share exchange or Change of Control of such owner or
otherwise.

         10.2 RIGHT OF FIRST OPTION AND RIGHT OF FIRST REFUSAL.

         (a) Except as provided in Section 10.6, without the consent of the
Partnership Governance Committee, no Partner may Transfer less than all of its
Units, and no Partner may Transfer its Units, directly or indirectly, for
consideration other than cash. Any Limited Partner and, in the case of OCC LP,
OCC GP (together, the "Selling Partners"), that receive a bona fide offer to
purchase all of their Units that the Selling Partners desire to accept (an
"Offer") or that otherwise 

                                       32
<PAGE>   38

desire to Transfer all of their Units to any Person shall give written notice
(the "Initial Notice") to the Partnership and the other Partners (the "Offeree
Partners") stating that the Selling Partners have received an Offer or otherwise
desire to Transfer their Units and shall set forth the cash purchase price and
all other terms of the Offer or the cash purchase price (established as provided
below) and all other terms on which they are willing to sell their Units (in
each case, the "Offer Terms"). In establishing the Offer Terms for a proposed
sale that does not involve an Offer, the Selling Partners shall obtain an
appraisal from an independent appraiser with a reasonable level of industry
experience of the cash price that a willing buyer under no compulsion to buy
would pay and a willing seller under no compulsion to sell would accept for the
Units of the Selling Partners (the "Appraised Value"). Delivery of an Initial
Notice shall constitute the irrevocable offer of the Selling Partners to sell
their Units to the Offeree Partners hereunder.

         (b) The Offeree Partners shall have the option, exercisable by
delivering written notice (the "Acceptance Notice") of such exercise to the
Selling Partners within 60 days of the date of the Initial Notice, to elect to
purchase all, but not less than all, of the Units of the Selling Partners on the
Offer Terms described in the Initial Notice. The Acceptance Notice shall set a
date for closing the purchase, such date to be not less than 30 nor more than 90
days after delivery of the Acceptance Notice; PROVIDED, HOWEVER, that such time
period shall be subject to extension as reasonably necessary (up to a maximum of
an additional 120 days after such 90 day period) in order to comply with any
applicable filing and waiting period requirements under the Hart-Scott-Rodino
Antitrust Improvements Act (or any successor statute) or other Legal
Requirement. The closing shall be held at the Partnership's offices. The
purchase price for the Selling Partners' Units shall be paid in immediately
available funds delivered at the closing, and all actions at the closing shall
conform in all material respects to the Offer Terms.

         (c) If the Offeree Partners do not elect to purchase all of the Selling
Partners' Units within 60 days after the receipt of the Initial Notice, the
Selling Partners shall have a further 180 days during which they may, subject to
Section 10.2(d), consummate the sale of their Units (i) substantially in
accordance with the terms of the Offer or (ii) if no Offer is involved, to a
third party purchaser on terms that are not substantially more favorable to such
purchaser than the Offer Terms and at a price equal to not less than 90% of the
Appraised Value of the Units. If the sale is not completed within such further
180-day period, the Initial Notice shall be deemed to have expired and a new
notice and offer shall be required before the Selling Partners may make any
Transfer of their Units. If the Selling Partners receive a written offer during
such further 180-day period from a third party purchaser that is for less than
90% of the Appraised Value, and the Selling Partners are willing to accept the
offer, then (1) the offer shall be treated as an Offer, and (2) the Selling
Partners must comply with the provisions of this Section 10.2 before the Selling
Partners may make any Transfer of their Units to the third party purchaser that
made the Offer.

         (d) Notwithstanding the foregoing provisions of this Section 10.2, a
Partner may Transfer its Units only if all of the following occur:

                                       33
<PAGE>   39

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

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

                  (iii) The Transfer does not cause a default under any material
         contract (A) that has been approved unanimously by the Partnership
         Governance Committee and (B) to which the Partnership is a party or by
         which the Partnership or any of its properties is bound.

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

                  (v) The transferor and transferee bear all reasonable costs
         incurred by the Partnership in connection with the Transfer.

                  (vi) The business and activities of the transferee comply with
         Section 9.6.

                  (vii) The provisions of Section 10.3 are satisfied.

                  (viii) The parent of the transferee satisfies the criteria set
         forth in Section 1.2(d)(vii) of the Parent Agreement and delivers an
         agreement to the Parent of the Offeree Partners and to the Partnership,
         substantially in the form of the Parent Agreement.

         10.3 INCLUSION OF GENERAL OR LIMITED PARTNER UNITS. OCC LP may not
Transfer its Units to any Person (other than in accordance with Section 10.6)
unless the Units of OCC GP are simultaneously transferred to such Person or a
Wholly-Owned Affiliate of such Person. OCC GP may not transfer its Units to any
Person (other than in accordance with Section 10.6) unless the Units of OCC LP
are simultaneously transferred to such Person or a Wholly-Owned Affiliate of
such Person.

         10.4 RIGHTS OF TRANSFEREE. Upon consummation of a Transfer in
accordance with Section 10.2, the transferee or transferees shall immediately,
and without any further action of any Person, become (i) a Substitute Limited
Partner if and to the extent Limited Partner Units are transferred and (ii) a
Substitute General Partner, if and to the extent General Partner Units are
transferred.

         10.5 EFFECTIVE DATE OF TRANSFER. Each Transfer shall become effective
as of the first day of the calendar month following the calendar month during
which the Partnership Governance Committee approves such Transfer and receives a
copy of the instrument of assignment and all such certificates and documents of
the character described in Section 10.2, which the Partnership Governance
Committee may reasonably request.

         10.6 TRANSFER TO 80%-OWNED AFFILIATE. Without the need for the consent
of any Person (subject to the provisions contained in Section 10.2(d) and this
Section 10.6):

         (a) any Partner may Transfer its Units to any 80%-Owned Affiliate of
such Partner. Upon consummation of a Transfer in accordance with this Section
10.6(a), the transferee shall immediately, and without any further action of any
Person, become (i) a Substitute Limited Partner, if and to the extent Limited
Partner Units are transferred, and (ii) a Substitute General Partner, if and to
the extent General Partner Units are transferred; and

         (b) OCC LP may, at its option and at any time, Transfer up to 99% of
its Limited Partner Units to OCC GP, whereupon such Limited Partner Units shall,
without any further action, become General Partner Units. Promptly following any
Transfer of Limited Partner Units in accordance with this Section 10.6(b), each
Partner shall take such actions and execute such instruments or documents
(including amendments to this Agreement or supplemental agreements hereto) as
may be reasonably necessary to ensure that OCC GP and OCC LP shall, taken as a
whole and following such Transfer, maintain all of its rights under this
Agreement as in effect immediately prior to such Transfer (including the portion
of any Partnership cash distributable to OCC GP and OCC LP).

         10.7 INVALID TRANSFER. No Transfer of Units which is in violation of
this Section 10 shall be valid or effective, and the Partnership shall not
recognize the same for the purposes of making any allocation or distribution.



                                   SECTION 11
                                     DEFAULT
                                     -------

         11.1 DEFAULT.

         (a) Each of the following events shall constitute a "Default" and
create the rights provided for in this Section 11 in favor of the Partnership
and the Non-Defaulting Partners against the Defaulting Partners:

                  (i) the failure by a Partner to make any contribution to the
         Partnership as required pursuant to this Agreement (other than pursuant
         to the Asset Contribution Agreement), which failure continues for at
         least five Business Days from the date that the Partner is notified
         such contribution is overdue; or

                  (ii) the withdrawal, retirement, resignation or dissolution of
         a Partner (other than in connection with a Transfer of all of a
         Partner's Units in accordance with this Agreement); or the Bankruptcy
         of a Partner or its Parent.

                                       35
<PAGE>   41

         (b) The day upon which the Default commences or occurs (or if the
Default is subject to a cure period and is not timely cured, then the day
following the end of the applicable cure period) shall be the "Default Date."
Without prejudice to a Partner's (or any of its Affiliates') rights to seek
temporary or preliminary judicial relief, prior to any such Default Date all
rights and obligations of the Partners under this Agreement shall remain in full
force and effect.

         11.2 REMEDIES FOR DEFAULT. Provided that there shall be no duplication
of remedies, without prejudice to any right to pursue independently and at any
time, including simultaneously, any other remedy it may have under law,
including the right to seek to recover Damages, or equity, the Non-Defaulting
Partners in their sole discretion may elect to pursue the following remedies:

         (a) At any time prior to the expiration of 60 days from the Default
Date, each of the Non-Defaulting Partners may elect to purchase its pro rata
share (based on the ratio of the number of Units owned by such Partners to the
number of Units owned by each of the Non-Defaulting Partners electing to
purchase) of the Units of the Defaulting Partners as described in Section 11.3;
PROVIDED, HOWEVER, that within 10 days after the determination of the Fair
Market Value, the Non-Defaulting Partners may withdraw their election, in which
case the Non-Defaulting Partners shall have an additional 30 days from their
determination not to proceed to elect an alternative remedy under Section
11.2(b) below; and

         (b) At any time prior to the expiration of 60 days from the Default
Date (or if the Non-Defaulting Partners initially elected to pursue their remedy
under Section 11.2(a) above, then at any time prior to the expiration of the
30-day extension period), the Non-Defaulting Partners may elect to effect a
liquidation of the Partnership under Section 11.4 and thereby cause the
Partnership to dissolve under Section 12.1(iv).

         11.3 PURCHASE OF DEFAULTING PARTNERS' UNITS.

         (a) Upon any election pursuant to Section 11.2(a), the purchase price
that the Non-Defaulting Partners shall pay, in the aggregate, to the Defaulting
Partners for their Units shall be an amount equal to (i) the amount that the
Defaulting Partners would receive in a liquidation (assuming that any sale under
Section 12.2 were for an amount equal to the Fair Market Value, without giving
effect to any Damages) reduced by (ii) the unrecovered Damages attributable to
the Default by the Defaulting Partners.

         (b) If the Non-Defaulting Partners have a right to purchase the Units
of the Defaulting Partners, they may first seek a determination of Fair Market
Value at the sole cost and expense of the Defaulting Partners by delivering
notice in writing to the Defaulting Partners. The Non-Defaulting Partners shall
have 10 days from the final determination of Fair Market Value to elect to
purchase the Defaulting Partner Units by delivering notice of such election in
writing, and the purchase shall be consummated prior to the expiration of 60
days from the date such notice is delivered; PROVIDED that, such time period
shall be subject to extension as reasonably necessary (up to a maximum of an
additional 120 days after such 60 day period) in order to comply with any

                                       36
<PAGE>   42

applicable filing and waiting period requirements under the Hart-Scott-Rodino
Antitrust Improvements Act or other Legal Requirement.

         (c) The purchase price so determined shall be payable in cash at a
closing held at the Partnership's offices. The purchase shall be consummated by
appropriate and customary documentation (including the giving of representations
and warranties substantially similar to those set forth in Sections 2.1 and 2.2
of the Master Transaction Agreement) as soon as practicable and in any event
within the applicable time period specified in subsection (b).

         (d) The Non-Defaulting Partners may assign, in whole or in part, their
right to purchase the Units of the Defaulting Partners to one or more third
parties without the consent of any Partner hereunder.

         (e) If Units are transferred in accordance with this Section 11.3,
whether to the Non-Defaulting Partners or a third party, upon the consummation
of such Transfer, each such transferee shall immediately, and without any
further action on the part of any Person, become (i) a Substitute Limited
Partner of the Defaulting Partner if and to the extent that Limited Partner
Units were transferred to such Person and (ii) a Substitute General Partner of
the Defaulting Partner if and to the extent that General Partner Units were
transferred to such Person.

         11.4 LIQUIDATION. Upon any election pursuant to Section 11.2(b), the
Non-Defaulting Partners shall have the right to elect to dissolve and liquidate
the Partnership pursuant to the procedures in Section 12.1(iv) (such procedures
constituting a "Liquidation"); PROVIDED, HOWEVER, that any amount payable to the
Defaulting Partners in such Liquidation pursuant to Section 12.2 shall be
reduced by, without duplication, any unrecovered Damages incurred by the
Non-Defaulting Partner and the Non-Defaulting Partners' Percentage Interest of
any unrecovered Damages incurred by the Partnership in connection with the
Default. The Non-Defaulting Partners shall deliver notice of such election to
dissolve and liquidate in writing to the Partnership and the Defaulting
Partners.

         11.5 CERTAIN CONSEQUENCES OF DEFAULT. Notwithstanding any other
provision of this Agreement, commencing on the Default Date and (i) prior to the
Non-Defaulting Partners' collection of Damages through the exercise of its legal
remedies or otherwise, or (ii) while the Non-Defaulting Partners are pursuing
their remedies under Section 11.2(a) or (b), the Representatives of the
Defaulting General Partner shall not have any voting or decisional rights with
respect to matters requiring Partnership Governance Committee Action, and such
matters shall be determined solely by the Representatives of the Non-Defaulting
General Partner; PROVIDED, HOWEVER, that the foregoing loss of voting and
decisional rights shall not occur as a result of a Default caused solely by the
Bankruptcy of a Partner or a Parent described in Section 11.1(a)(ii); and
PROVIDED FURTHER, that in the case of a Default under Section 11.1(a)(i), the
foregoing loss of voting and decisional rights shall not apply to those voting
and decisional rights contained in Sections 6.7(i), (viii), (xi) or (xiii) of
this Agreement, which rights shall continue in full force and effect at all
times.

                                   SECTION 12
                    DISSOLUTION, LIQUIDATION AND TERMINATION
                    ----------------------------------------

         12.1 DISSOLUTION AND TERMINATION. As long as Geon LP is willing then to
convert its Units to General Partner Units and thereafter serve as the General
Partner (who is hereby authorized in such event to so convert its Units and to
conduct the business of the Partnership without dissolution), the withdrawal,
retirement, resignation, dissolution or Bankruptcy of the General Partner shall
not dissolve the Partnership, but rather shall be a Default covered by Section
11. The Partnership shall be dissolved upon the happening of any one of the
following events:

                  (i) the written determination of both the General Partner and
         Geon LP to dissolve the Partnership;

                  (ii) the entry of a judicial decree of dissolution;

                  (iii) any other act or event that results in the dissolution
         of a limited partnership under the Act (except as provided in the first
         sentence of this Section 12.1);

                  (iv) the election of the Non-Defaulting Partners to effect a
         dissolution of the Partnership under Section 11.4; or

                  (v) after the delivery of a Deadlock Notice by either the
         General Partner or Geon LP pursuant to Section 8.5, the written
         determination by either the General Partner or Geon LP to dissolve the
         Partnership.

         12.2 PROCEDURES UPON DISSOLUTION.

         (a) GENERAL. If the Partnership dissolves, it shall commence winding-up
pursuant to the appropriate provisions of the Act and the procedures set forth
in this Section 12. Notwithstanding the dissolution of the Partnership, prior to
the termination of the Partnership, the business of the Partnership and the
affairs of the Partners, as such, shall continue to be governed by this
Agreement.

         (b) CONTROL OF WINDING-UP. The winding up of the Partnership shall be
conducted under the direction of the Partnership Governance Committee; PROVIDED,
HOWEVER, that (i) if OCC GP and OCC LP are then Defaulting Partners and Geon LP
is a Non-Defaulting Partner, such winding-up shall be conducted under the
direction of Geon LP, and (ii) if the dissolution is caused by entry of a decree
of judicial dissolution, the winding-up shall be carried out in accordance with
such decree. The term "Liquidator" shall mean the Person or committee conducting
such winding-up of the Partnership.

         (c) MANNER OF WINDING-UP. Unless the provisions of Section 12.2(e)
apply, the Liquidator shall cause the Partnership to attempt to sell all
Partnership properties and apply the 

                                       38
<PAGE>   44

proceeds therefrom in accordance with this Section 12.2(c) and Section 12.2(d).
Upon dissolution of the Partnership and subject to Section 12.2(f), the
Liquidator shall determine the time, manner and terms of any sale or sales of
Partnership property pursuant to such winding-up, consistent with its duties and
having due regard to the activity and condition of the relevant market and
general financial and economic conditions. Except as otherwise agreed by the
Partners, no distributions will be made in kind to any Partner without the
consent of each Partner.

         (d) APPLICATION OF ASSETS. In the case of a dissolution and winding-up
of the Partnership, the Partnership's assets shall be applied as follows:

                  (i) First, to satisfaction of the liabilities of the
         Partnership owing to creditors (including Partners and Affiliates of
         the Partners who are creditors), whether by payment or reasonable
         provision for payment. Any reserves created to make any such provision
         for payment may be paid over by the Partnership to an independent
         escrow holder or trustee, to be held in escrow or trust for the purpose
         of paying any such contingent, conditional or unmatured liabilities or
         obligations, and, at the expiration of such period as the Liquidator
         may deem advisable, such reserves shall be distributed to the Partners
         or their assigns in the manner set forth in Section 12.2(d)(ii) below.

                  (ii) Second, after all allocations of Profits or Losses and
         other items pursuant to Section 4, to the Partners in accordance with
         the balances in their Capital Accounts.

                  (iii) Notwithstanding the foregoing, if any Partner shall be
         indebted to the Partnership, then until payment in full of the
         principal of and accrued but unpaid interest on such indebtedness,
         regardless of the stated maturity or maturities thereof, the
         Partnership shall retain such Partner's distributive share of
         Partnership property and apply such sums to the liquidation of such
         indebtedness and the cost of operation of such Partnership property
         during the period of such liquidation.

         (e) DIVISION OF ASSETS UPON DEADLOCK. If dissolution occurs pursuant to
Section 12.1(v), then the provisions of this Section 12.2(e) shall, if elected
by any Partner, apply in lieu of the provisions of Section 12.2(c), but subject
to the provisions of Section 12.2(d)(ii). In such event, the Partnership
properties shall be divided and distributed in kind to the Partners in
accordance with the provisions of Appendix E.

         (f) SUPPLY AGREEMENTS. In connection with a sale of Partnership
properties pursuant to Section 12.2(c), the Liquidator shall, at its option,
either (i) if a single purchaser acquires all or substantially all of such
properties, cause such purchaser to assume and agree to perform under all the
Supply Agreements, or if such properties are sold to more than one purchaser,
cause such purchasers (on a several basis) in the aggregate to assume and agree
to perform under all the Supply Agreements, with the benefits, duties and
obligations under the Supply Agreements being allocated among such purchasers as
deemed appropriate by the Liquidator, or (ii) cause the Supply Agreements to be
terminated prior to the sale of such properties with the purchaser or purchasers
of 

                                       39
<PAGE>   45

such properties not assuming the Supply Agreements, and prior to any
distribution of the Partnership's assets in connection with the dissolution and
winding-up of the Partnership, cause the Partnership to pay Geon LP in cash an
amount equal to the remaining value of the Supply Agreements (to the parties
thereto other than the Partnership) as of the date of the termination of the
Supply Agreements, assuming the extension of the Supply Agreements beyond their
respective initial terms pursuant to Geon's two five-year renewal options. The
Partners agree that any dispute regarding the value of the Supply Agreements
shall be resolved pursuant to the Dispute Procedures.

         12.3 TERMINATION OF THE PARTNERSHIP. Upon the completion of the
liquidation of the Partnership and the distribution of all Partnership assets,
the Partnership's affairs shall terminate and the Partnership shall cause to be
executed and filed a Certificate of Cancellation of the Partnership's
Certificate of Limited Partnership pursuant to the Act, as well as any and all
other documents required to effectuate the termination of the Partnership.

         12.4 ASSET AND LIABILITY STATEMENT. Within a reasonable time following
the completion of the winding-up and liquidation of the Partnership's business,
the Liquidator shall supply to each of the Partners a statement (which may be
unaudited) which shall set forth the assets and the liabilities of the
Partnership as of the date of complete liquidation, and each Partner's pro rata
portion of distributions pursuant to Section 12.2.



                                   SECTION 13
                                 MISCELLANEOUS
                                 -------------

         13.1 CONFIDENTIALITY AND USE OF INFORMATION.

         (a) Except as provided in Section 13.1(c) or (d), each Partner shall,
and shall cause each of its Affiliates and its and their respective partners,
shareholders, directors, officers, employees and agents (collectively, "Related
Persons") to, keep secret, retain in strictest confidence, and not distribute,
disseminate or disclose any and all Confidential Information except to (i) the
Partnership and its officers and employees, (ii) any lender to the Partnership
or (iii) any Partner or any of their respective Affiliates or other Related
Persons on a "need to know" basis in connection with the transactions leading up
to and contemplated by this Agreement and the operation of the Partnership, and
such Partner disclosing Confidential Information pursuant to this Section
13.1(a) shall use, and shall cause its Affiliates and other Related Persons to
use, such Confidential Information only for the benefit of the Partnership in
conducting the Partnership's business or for any other specific purposes for
which it was disclosed to such Person; PROVIDED THAT the disclosure of financial
statements of, or other information relating to the Partnership shall not be
deemed to be the disclosure of Confidential Information (y) to the extent that
any Partner (or its ultimate parent entity) deems it necessary, appropriate or
customary pursuant to law, regulation or stock exchange rule (in the reasonable
good faith judgment of such parent entity) to disclose such information in or in
connection with filings with the SEC, press releases disseminated to the
financial community, presentations to lenders, presentations to ratings agencies
or information disclosed to similar 

                                       40
<PAGE>   46

audiences or (z) to the extent that in order to sustain a position taken for tax
purposes, any Partner deems it necessary and appropriate to disclose such
financial statements or other information. All Confidential Information
disclosed in connection with the Partnership or pursuant to this Agreement shall
remain the property of the Person whose property it was prior to such disclosure
unless such property has been transferred to the Partnership pursuant to an
Asset Contribution Agreement.

         (b) No Confidential Information regarding the plans or operations of
any Partner or any Affiliate thereof received or acquired by or disclosed to any
unaffiliated Partner or Affiliate thereof in the course of the conduct of
Partnership business, or otherwise as a result of the existence of the
Partnership, may be used by such unaffiliated Partner or Affiliate thereof for
any purpose other than for the benefit of the Partnership in conducting the
Partnership Business. The Partnership and each Partner shall have the
affirmative obligation to take all necessary steps to prevent the disclosure to
any Partner or Affiliate thereof of information regarding the plans or
operations of such Partner and its Affiliates in markets and areas unrelated to
the business of the Partnership in which any other Partner or its respective
Affiliate competes.

         (c) In the event that any Partner is legally required (by
interrogatories, discovery requests for information or documents, subpoena,
civil investigative demand or similar process) to disclose any Confidential
Information, it is agreed that such Partner prior to disclosure will provide the
Partnership Governance Committee with prompt notice of such request(s) so that
the Partnership Governance Committee may seek an appropriate protective order or
other appropriate remedy and/or waive the Partner's compliance with the
provisions of this Section. In the event that such protective order or other
remedy is not obtained, or that the Partnership Governance Committee grants a
waiver hereunder, such Partner may furnish that portion (and only that portion)
of the Confidential Information that, in the opinion of the Partner's counsel,
the Partner is legally compelled to disclose, and the Partner will exercise its
commercially reasonable best efforts to obtain reliable assurance that
confidential treatment will be accorded any Confidential Information so
furnished.

         (d) Any Partner may disclose Confidential Information to a third party
who requires such Confidential Information for the purpose of evaluating a
possible purchase of such Partner's Units in accordance with Section 10;
PROVIDED, HOWEVER, that such third party shall be informed by such Partner of
the confidential nature of the information and the existence of this Section
13.1 and prior to any disclosure shall execute a written confidentiality
agreement with such Partner substantially identical in scope to this Section and
providing that such confidentiality agreement is also made for the benefit of
the Partnership and each of the other Partners.

         (e) The Partners and their Affiliates shall consult with each other on
an ongoing basis with respect to disclosures regarding the Partnership and its
business and affairs permitted under Section 13.1(a)(y).

         13.2 INDEMNIFICATION.

         (a) INDEMNIFICATION BY PARTNERSHIP. The Partnership agrees, to the
fullest extent permitted by applicable law, to indemnify, defend and hold
harmless each Partner, its Affiliates and their respective officers, directors
and employees from, against and in respect of any Liability which such
Indemnified Party may sustain, incur or assume as a result of, or relative to, a
Third Party Claim arising out of or in connection with the business, property or
affairs of the Partnership, except to the extent that it is Finally Determined
that such Third Party Claim arose out of or was related to actions or omissions
of the indemnified Partner, its Affiliates or any of their respective officers,
directors or employees (acting in their capacities as such) constituting a
breach of this Agreement or any Related Agreement. The Partnership shall
periodically reimburse or advance to any Person entitled to indemnity under this
Section 13.2(a) its legal and other expenses incurred in connection with
defending any claim with respect to such Liability if such Person shall agree to
reimburse promptly the Partnership for such amounts if it is finally determined
that such Person was not entitled to indemnity hereunder. Nothing in this
Section 13.2(a) is intended to, nor shall it, affect or take precedence over the
indemnity provisions contained in any Related Agreement.

         (b) PARTNER'S RIGHT OF INDEMNIFICATION. Each Partner hereby agrees, to
the fullest extent permitted by law, to indemnify, defend and hold harmless the
other Partners, their Affiliates and their respective officers, directors and
employees from and against the indemnifying Partner's Percentage Interest
(calculated at the time any such Liability was incurred) of any Liability that
such Indemnified Party may sustain, incur or assume as a result of or relating
to any Third Party Claim arising out of or in connection with the business,
property or affairs of the Partnership; PROVIDED, HOWEVER, that such indemnified
Partner, its Affiliates and their respective officers, directors and employees
shall not be entitled to indemnity under this Section 13.2(b) to the extent that
it is Finally Determined that such Third Party Claim arose out of or was related
to actions or omissions of the indemnified Partner, its Affiliates or any of
their respective officers, directors or employees (acting in their capacities as
such) constituting a breach of this Agreement or any Related Agreement;
PROVIDED, FURTHER, that such indemnified Partner, its Affiliates and their
respective officers, directors and employees shall not be entitled to indemnity
under this Section 13.2(b) unless (i) the indemnified Partner shall first make a
written demand for indemnification from the Partnership in accordance with
Sections 13.2(a) and (c) and the Partnership shall fail to satisfy such demand
in a manner reasonably satisfactory to the indemnified Partner within 60 days of
such notice or (ii) the Partnership is insolvent or otherwise unable to satisfy
its obligations. The indemnifying Partner shall periodically reimburse any
Person entitled to indemnity under this Section 13.2(b) for its legal and other
expenses incurred in connection with defending any claim with respect to such
Liability if such Person shall agree to reimburse promptly the indemnifying
Partner for such amounts if it is Finally Determined that such Person was not
entitled to indemnity hereunder.

         (c) PROCEDURES. Promptly after receipt by a Person entitled to
indemnification under subsection (a) or (b) (an "Indemnified Party") of notice
of any pending or threatened claim against it (a "Claim"), such Indemnified
Party shall give prompt written notice (including copies of all papers served
with respect to such claim) to the Person to whom the Indemnified Party is
entitled 

                                       42
<PAGE>   48

to look for indemnification (the "Indemnifying Party") of the commencement
thereof, 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 the
failure to so notify the Indemnifying Party shall not relieve the Indemnifying
Party of any liability that it may have to any Indemnified Party except to the
extent the Indemnifying Party demonstrates that it is prejudiced thereby. In
case any Claim that is subject to indemnification under Section 13.2(a) shall be
brought against an Indemnified Party and it shall give notice to the
Indemnifying Party of the commencement thereof, the 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 by making any counterclaim against the Person
asserting the Third Party Claim or any cross-complaint against any Person, 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.

         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 this Section 13.2(c), or if the Indemnifying Party assumes the
defense of the Indemnified Party pursuant to this Section 13.2(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 

                                       43
<PAGE>   49

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.

         Notwithstanding the other provisions of this Section 13.2, if the
Indemnifying Party disputes its potential liability to the Indemnified Party
under this Section 13.2 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
13.2 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.

         After it has been mutually agreed or Finally Determined that an
Indemnifying Party is liable to the Indemnified Party under this Section
13.2(c), 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.

         (d) SURVIVAL. The indemnities contained in this Section shall survive
the termination and liquidation of the Partnership.

         (e) SUBROGATION. In the event of any payment by or on behalf of an
Indemnifying Party to an Indemnified Party in connection with any Liability, the
Indemnifying Party (or any guarantor who made such payment) 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 (not including the Partnership) relating to such
event or indemnification, but only to the extent of any such payments. The
Indemnified Party shall cooperate with the Indemnifying Party (or such
guarantor) in any reasonable manner in prosecuting any subrogated claim.

         (f) NO LIMITATION. Nothing in this Agreement shall be deemed to (i)
limit the Partnership's power to indemnify its officers, employees, agents or
any other Person, to the fullest extent permitted by law, or (ii) limit the
Partnership's indemnity obligations to the Partners under the Act.

         13.3 THIRD PARTY CLAIM REIMBURSEMENT.

         (a) In the case of a Liability relating to a Third Party Claim and
caused by the Fault of either the General Partner or Geon LP, its Affiliates or
any of their respective officers, directors or employees (acting in their
capacities as such) against whom reimbursement is being sought, such Partner,
whether the General Partner or Geon LP, hereby agrees to reimburse the
Partnership for such Liability to the extent that:

                                       44
<PAGE>   50

                  (i) the Liability relates to a Third Party Claim that has been
         finally resolved and that the Partnership has actually paid (an
         "Expense");

                  (ii) the Expense is not covered by insurance proceeds actually
         received by the Partnership under policies of a nature such that future
         premium rates thereunder will not be increased by claim experience
         relating to such Liability; PROVIDED that, if the Partnership is
         reimbursed by either the General Partner or Geon LP pursuant to this
         Section 13.3(a) and subsequently receives insurance proceeds covering
         such Expense under policies of a nature that future premium rates
         thereunder will not be increased by claim experience relating to such
         Liability, the Partnership shall promptly pay such insurance proceeds
         to the reimbursing Partner up to the amount reimbursed by such Partner;
         and

                  (iii) the Expense is not offset by third party indemnification
         or otherwise;

PROVIDED, HOWEVER, that such reimbursing Partner shall reimburse the Partnership
for the Expense only to the extent and in proportion to its Fault.

         (b) Any claim by the Partnership for reimbursement under this Section
may be initiated by either the General Partner or Geon LP upon written notice to
the other, and the General Partner and Geon LP shall have a period of 60 days
during which to reach unanimous agreement as to the terms on which any
reimbursement shall be made. If the General Partner and Geon LP are unable to
agree or there are any disputes over Fault and reimbursement under this Section,
such matters shall be resolved pursuant to the Dispute Procedures.

         13.4 DISPUTE RESOLUTION. Except as otherwise provided for herein, all
controversies or disputes arising under this Agreement shall be resolved
pursuant to the provisions set forth on Appendix D (the "Dispute Procedures").

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

         13.6 FURTHER ASSURANCES. From time to time, each Partner agrees to
execute and deliver such additional documents, and will provide such additional
information and assistance, as the Partnership may reasonably require to carry
out the terms of this Agreement and to accomplish the Partnership's business.

                                       45
<PAGE>   51

         13.7 SUCCESSORS AND ASSIGNS. Except as may be expressly provided
herein, this Agreement shall be binding upon and inure to the benefit of the
successors of the Partners, but no Partner may assign or delegate any of its
rights or obligations under this Agreement. Except as expressly provided herein,
any purported assignment or delegation shall be void and ineffective.

         13.8 BENEFITS OF AGREEMENT RESTRICTED TO THE PARTIES. This Agreement is
made solely for the benefit of the Partnership and the Partners, and no other
Person, including any officer or employee of the Partnership or any Partner,
shall have any right, claim or cause of action under or by virtue of this
Agreement.

         13.9 NOTICES. All notices, requests and other communications that are
required or may be given under this Agreement shall, unless otherwise provided
for elsewhere in this Agreement, be in writing and shall be deemed to have been
duly given if and when (i) transmitted by telecopier facsimile during business

provisions of this Section 13.17 shall govern and control; (ii) the aggregate of
all interest under Applicable Usury Laws that is contracted for, charged or
received under this Agreement shall under no circumstances exceed the Maximum

the extent that it is in excess of the Maximum Amount; and (iv) the effective
rate of any interest payable under this Agreement shall be IPSO FACTO reduced to
the Highest Lawful Rate, and the provisions of this Agreement immediately shall

agreed to be paid, to any person pursuant to this Agreement for the use,
forbearance or detention of any indebtedness arising hereunder shall, to the
fullest extent permitted by the Applicable Usury Laws, be amortized, pro rated,
allocated and spread throughout the full term of any such indebtedness so that
the actual rate of interest does not exceed the Highest Lawful Rate in effect at
any particular time during the full term thereof.

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


         (1) BINDING AND EXCLUSIVE MEANS. Except as otherwise provided in the
Partnership Agreement, the dispute resolution provisions set forth in this
Appendix shall be the binding and exclusive means to resolve all disputes
arising under the Agreement (each a "Dispute").

         (2) STANDARDS AND CRITERIA. In resolving any Dispute, the standards and
criteria for resolving such Dispute shall, unless the Partners involved in the
Dispute in their discretion jointly stipulate otherwise, be as set forth in
Appendix 1 to this Appendix.

         (3) ADR AND BINDING ARBITRATION PROCEDURES. If a Dispute arises, the
following procedures shall be implemented (with references to "Partners" meaning
the Partners involved in the Dispute):

         (a) Any Partner may at any time invoke the dispute resolution
procedures set forth in this Appendix as to any Dispute by providing written
notice of such action to the Secretary of the Partnership, who within five
Business Days after such notice shall schedule a meeting to be held in Dallas,
Texas between the Partners. The Partners' meeting shall occur within 10 Business
Days after notice of the meeting is delivered to the Partners. The meeting shall
be attended by representatives of each Partner 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 Partners 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 Partners resolving the Dispute; (ii) one of the Partners shall determine
and notify the other Partners 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 Partners
having resolved the Dispute; or (iv) if another technique of alternative dispute
resolution is not agreed upon, two full Business Days (or such other time period
as may be agreed upon) shall expire without the Partners having resolved the
Dispute.

         (c) If, as of the Interim Decision Date, the Partners have not
succeeded in negotiating a resolution of the Dispute pursuant to subsection (b),
the Partners 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 Partner
involved in the Dispute (the "Disputing Partner"). 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 Dallas, 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 Partner shall make
available to the Arbitrator and the other Partners all books, records and other
information within its control requested by the other Partners 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 Partners
for an expeditious means of dispute resolution, the Arbitrator may limit the
scope of discovery between the Partners as may be reasonable under the
circumstances. In deciding the substance of the Partners' 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
conflicts of law principles. The arbitration hearing shall be commenced promptly
and conducted expeditiously, with each Partner involved in the Dispute being
allocated an equal amount of time for the presentation of its case. Unless
otherwise agreed to by the Partners, 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 Partners if, upon a showing of good cause, that Partner 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 Partners.

         (e) The Disputing Partner shall notify the American Arbitration
Association ("AAA") and the other Partners 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 receipt of the
Dispute Notice by all of the Partners 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 Partners 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' costs and attorneys' fees and expenses) against any
or all Partners.

         (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, 

                                  Appendix D-2

<PAGE>   73


indirect, punitive, exemplary, special or other similar 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, punitive, exemplary, special
or other similar 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
Partners, 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, the
Partners 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 Partners and their Affiliates as set forth in the Partnership 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 Partnership Agreement and the Related Agreements and
permits the Partners to realize the benefits intended to be afforded thereby.

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

                                   APPENDIX E

                        DIVISION OF PARTNERSHIP BUSINESS
                        --------------------------------

         If the Partnership is dissolved and Section 12.2(e) applies to the
winding-up of the affairs of the Partnership, the Partnership properties shall,
to the extent legally and contractually feasible and, after satisfaction of the
liabilities of the Partnership (whether by payment or reasonable provision for
payment), be distributed in kind to the Partners in accordance with a division
(the "Division") of the properties. The Division shall be implemented by
dividing the properties, to the extent feasible, in accordance with the
following priorities and principles:

A.       First priority shall be given to maximizing the consistency of the
         Division with a division of the Partnership properties that allocates
         to each Partner (subject to such Partner's Percentage Interest of the
         Partnership's liabilities) Partnership properties in proportion to the
         value of such Partner's Percentage Interest in the Partnership's
         business taking into account the aggregate Asset Fair Market Value of
         the Partnership's properties and the value and benefits afforded to
         such Partner under the Partnership Agreement and the other Related
         Agreements.

B.       Second priority shall be given to the allocation of the Partnership's
         various assets and business units between the Partners so as to
         maximize the aggregate going concern value of the respective assets and
         business units allocated to each Partner, taking into account, without
         limitation, the potential synergies and efficiencies that are
         reasonably achievable in connection with the operation of such
         allocated assets and business units as an independent business entity.

C.       Third priority shall be given to maximizing the consistency of the
         Division with the nature and quality of the Assets and Contributed
         Business originally transferred to the Partnership by the respective
         Partners or their Affiliates.

         Absent an agreement by the Partners or direction by the Neutral as to
both (i) how the Partners should allocate Partnership debt and (ii) the process
for relieving each Partner of liability for that portion of Partnership debt
allocated to the other Partner, the Partners (A) shall be jointly and severally
liable to the holders of all Partnership debt and (B) as between the Partners,
each Partner shall be obligated to pay to holders of the debt its Percentage
Interest of all payments of principal and interest on Partnership debt.
Notwithstanding the foregoing, the Neutral shall be entitled to direct, and any
Partner may propose, an alternative allocation of Partnership debt in any
circumstance where such alternative allocation is reasonably likely to result in
a Division that is more consistent with the priorities outlined above.

         For purposes of this Appendix E, OCC GP and OCC LP shall be treated as
if they were a single Partner.

                                  Appendix E-1

<PAGE>   76


         The Partners shall attempt to agree on a plan for a mutually acceptable
Division. If they are unable to so agree after 60 days following the occurrence
of the dissolution, a Neutral shall be appointed in accordance with Appendix D
and each Partner shall submit to the Neutral a written proposal for a Division.
The Neutral shall decide which of the two proposals (without in any way
modifying or compromising between the two proposals) more closely follows the
priorities and principles set forth above, and the proposal so chosen shall
thereupon be binding upon all Partners and shall be promptly implemented under
the direction of the Neutral. The Neutral shall be entitled to employ (at the
expense of the Partnership) such financial and accounting advisors and legal
counsel as he or she shall select, provided that no such advisor or counsel
shall have any affiliation with any Partner.

         1.6   [Intentionally Omitted].

         1.7   EMPLOYEE MATTERS.

         (a) In accordance with and subject to Section 3.7 of the Master
Transaction Agreement, the Partnership shall offer employment to certain
Salaried Employees and to each Union Employee in accordance with the terms and
conditions negotiated between the Partnership and the Unions. Any Employee that
accepts such offer is hereinafter referred to as a "Partnership Employee."
Partnership Employees shall be employed effective as of the Asset Transfer
Effective Time. Notwithstanding the foregoing, if as of the Asset Transfer
Effective Time, 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 an offer of employment, such Employee shall become employed by the
Partnership (and become a Partnership Employee for purposes of this Section 1.7)
upon eligibility to return to active employment with Contributor under the
applicable conditions of the short term disability benefits or sick pay plan of
Contributor, or upon return from leave of absence. Such Employee's employment by
the Partnership shall not be effective until 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, Contributor
shall continue to bear all costs and expenses associated with such Employee.

         (b) Contributor shall remain solely responsible for (i) any liability
with respect to Tier 1 Employees who do not become Partnership Employees (as
well as any employees of Contributor who do not become Partnership Employees and
who are not Tier 1 Employees, Tier 2 Employees or Plant Employees), including
any liability for severance benefit payments and any costs associated with
violations of any Legal Requirements; (ii) bonus or executive compensation, if
any, to Employees covered by Contributor's bonus or executive compensation
programs; and (iii) any liability related to the termination of any employees of
Contributor or any of its Affiliates at any time prior to the Asset Transfer
Effective Time, including liability for all severance benefit payments to such
employees pursuant to any applicable severance plan and any costs associated
with violations of any Legal Requirements. With respect to Employees who become
Partnership Employees, Contributor shall pay prior to the Asset Transfer
Effective Time bonus or executive compensation earned in 1998. Contributor shall
promptly reimburse the Partnership for a pro rata portion of any bonus or
executive compensation paid by the Partnership that is earned in 1999 by
Partnership 

                                      -6-

Employees, based on the months of employment in 1999 with Contributor prior to
the Asset Transfer Effective Time. 

         (c) The Partnership shall be responsible for any severance costs with
respect  to Plant Employees pursuant to the applicable plan or program of the
Partnership, as applicable to such Employee and in effect as of the termination
date of such Employee. Any Partnership Employee whose employment is terminated
by the Partnership within six months after the Asset Transfer Effective Time
shall be entitled to receive a severance benefit from the Partnership not       
less than the benefits, if any, provided under the severance plan of
Contributor in effect as of the Asset Transfer Effective Time.

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

         (e) With regard to the Contributed Business, the Partnership shall not
at any time prior to 60 days after the Asset Transfer Effective Time, effectuate
a "plant closing" or a "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 or operating unit, or any Employees
without complying fully with the notice and all other applicable requirements of
WARN.

         (f) As of the Asset Transfer Effective Time, the Partnership shall
provide each Salaried Employee that is a Partnership Employee with "Partnership
Benefit Plans," which shall mean the benefit plans and programs under (i) Plans
effective immediately prior to the Asset Transfer Effective Time, (ii) the
benefit plans and programs applicable to employees of OCC in similar jobs, or
(iii) a combination of the Plans and OCC's benefit plans and programs, the
determination of which shall be at the sole discretion of the Partnership. From
and after the Asset Transfer Effective Time, each Salaried Employee that is a
Partnership Employee shall be eligible to participate in such Partnership
Benefit Plans in accordance with the terms and conditions thereof. Under such
Partnership Benefit Plans that are Employee Welfare Benefit Plans, Salaried
Employees that are Partnership Employees and their eligible dependents, if
participants in any health, long term disability or life insurance plans, as
applicable, of Contributor immediately prior to the Asset Transfer Effective
Time, (i) shall participate in such Partnership Benefit Plans as of the Asset
Transfer Effective Time, and (ii) 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 Asset Transfer Effective Time. In
addition, amounts paid by such Salaried Employees that are Partnership Employees
towards deductibles and copayment limitations under the health plans of
Contributor shall be counted toward meeting any similar deductible and copayment
limitations under the health plans that shall be provided under the Partnership
Benefit Plans.

         (g) The Partnership shall recognize all service credited for each of
the Salaried Employees that are Partnership Employees on Contributor's records
for purposes of eligibility for 

                                      -7-
<PAGE>   12

benefits and vesting under the Partnership Benefit Plans and the level of
benefits under the Partnership Benefit Plans, but no such recognition will be
made for any benefit accrual under any Partnership Benefit Plan that is a
defined benefit pension plan.

         (h) Contributor agrees that, for Partnership Employees with an accrued
benefit under any Employee Pension Benefit Plan, Contributor shall, or shall
cause an Affiliate, as appropriate, to amend such Employee Pension Benefit Plans
so that full vesting in such accrued benefits shall occur as of the Asset
Transfer Effective Time.

         (i) Contributor and the Partnership shall take all necessary and
reasonable steps to prevent a default of any loans of any Partnership Employee
under the Geon Retirement Savings Plan ("Contributor's 401(k) Plan"), including
taking prompt action to provide for a plan-to-plan asset transfer (as such
transfer is defined in section 414(l) of the Code) of account balances
(including outstanding loans) of those Partnership Employees who so elect to
transfer from Contributor's 401(k) Plan to the appropriate Partnership Benefit
Plan pursuant to section 401(k) of the Code.

         (j) From and after the Asset Transfer Effective Time, Salaried
Employees that are Partnership Employees shall be entitled to retain and take
any paid vacation days accrued during the period from January 2, 1999 through
the Asset Transfer Effective Time but not taken under Contributor's vacation
policy, if applicable. On or promptly after the Asset Transfer Effective Time,
Contributor shall pay any Banked Vacation to each Salaried Employee. "Banked
Vacation" shall mean vacation time accrued on Contributor's records as payable
to any Salaried Employee who becomes a Partnership Employee for which vacation
time has not been taken prior to January 2, 1999.

         (k) Contributor and the Partnership agree that they will satisfy their
respective obligations, if any, under the National Labor Relations Act regarding
Union Employees. The Partnership will recognize each Union, and each Union
Employee shall participate in such plans and programs as are applicable to the
Union Employees in accordance with the terms and conditions negotiated by the
Partnership.

         (l) From and after the Asset Transfer Effective Time, Employees that
are Partnership Employees shall cease to accrue service credit and benefits,
except as expressly provided in this Section 1.7, under any and all welfare
plans of Contributor and its Affiliates, under any and all pension plans of
Contributor and its Affiliates, and under any and all non-ERISA plan or programs
of Contributor and its Affiliates, in which participation had been available to
such Employees prior to the Asset Transfer Effective Time; provided, however,
that Contributor at its sole expense may provide additional benefits to such
Partnership Employees.

         (m) Except as otherwise provided in this Section 1.7, Contributor and
the Partnership agree that this Agreement does not contemplate the transfer of
any assets or liabilities from any benefit plan of Contributor to any
Partnership Benefit Plan. The Partnership hereby waives any and all claims that
the Partnership or any of its Affiliates might have to any of the assets of any
plan of Contributor or its Affiliates.

         (n) Except with respect to Assumed Liabilities (other than Assumed
Liabilities described in Section 1.5(a)(v)), Contributor 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 any benefit plan of Contributor), and worker's compensation
for employees of Contributor (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 Asset Transfer
Effective Time. In addition, except with respect to Assumed Liabilities (other
than Assumed Liabilities described in Section 1.5(a)(v)), Contributor 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 benefits or other welfare benefits by, Exposure Claims by,
or any other item of compensation or benefits payable under any Contributor Plan
to, (i) any employee of Contributor after the Asset Transfer Effective Time, and
(ii) any former employee of Contributor who retired, died, became disabled or
otherwise terminated employment prior to the Asset Transfer Effective Time.
Expenses and benefits relating to such claims incurred by Partnership Employees
and their covered dependents attributable to employment with the Partnership on
or after the Asset Transfer Effective Time shall be the sole responsibility of
the Partnership under the terms of its benefit plans. For the purposes of this
Section 1.7(n), a claim is deemed incurred when the medical or other therapeutic
services giving rise to the claim were performed.

         (o) Except as otherwise specified in this Section 1.7 and except with
respect to Exposure Claims, the Partnership hereby agrees to indemnify
Contributor and its Affiliates and to defend and hold Contributor and its
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 Contributor and its Affiliates and arising out
of or otherwise in respect of the following:

                  (i) any failure by the Partnership to comply with its
         obligations hereunder or otherwise with respect to any Partnership
         Employee;

                  (ii) any suit or claim of violation brought against
         Contributor or its Affiliates under WARN for any actions taken by the
         Partnership after the Asset Transfer Effective Time with regard to the
         Partnership Employees at any facility, site of employment or operating
         unit affected by this Agreement;

                  (iii) all claims by any Partnership Employee attributable to
         employment after the Asset Transfer Effective Time who the Partnership
         or its Affiliates actually or constructively terminates or by any
         spouse, dependent, estate or other beneficiary of such Employee; or

                  (iv) any claims or charges by or relating to Employee
         concerning wrongful termination, discrimination, harassment, or
         violation of (1) the Fair Labor Standards Act, (2) the Labor Management
         Relations Act, (3) WARN, (4) the Americans With Disabilities Act, (5)
         ERISA, (6) the Consolidated Omnibus Budget Reconciliation Act of 1985,

         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 Asset Transfer
Effective Time.

         (p) Nothing expressed or implied in this Agreement shall confer upon
any Employee or any other Person other than the parties hereto, 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.

         (q) Except as otherwise specified in this Section 1.7 and except with
respect to Assumed Liabilities (other than the Assumed Liabilities described in
Section 1.5(a)(v)), Contributor agrees 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 benefit plans, or claims of

the Employees at mutually agreeable times prior to the Asset Transfer Effective
Time to explain and answer questions about the conditions, policies and benefits
of employment by Partnership after the Asset Transfer Effective Time.
Contributor shall cooperate with the Partnership until the Asset Transfer
Effective Time in communicating to such Employees any additional information
concerning employment after the Asset Transfer Effective Time 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, Contributor and the Partnership agree to furnish each other with
appropriate records for each of the Employees, subject to customary
confidentiality restrictions, compliance with Legal Requirements and appropriate
employee consents, as may be necessary to assist in proper benefit
administration.

         1.8   JOINT CONTRACTS.

         (a) Any Contributed Contracts contributed to the Partnership pursuant
to Section 1.1 that relate principally to the Contributed Business but also
relate to the business (other than the Contributed Business) of Contributor or
its Affiliates will be made available to Contributor and its Affiliates by the
Partnership pursuant to arrangements by which 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 Contributor or its Affiliates but also relate to
the Contributed Business will be made available to the Partnership by
Contributor or its Affiliates pursuant to 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 Contributor or its Affiliates.

         1.9 RETAINED BUSINESS; SUPPORT SERVICES. In addition to the
Partnership's rights under the Related Agreements, for two years from the date
hereof, the Partnership shall have the right to purchase services from the
Retained Business at full cost and otherwise on arms'-length terms, in all cases
where it is reasonable under all the circumstances for the Retained Business to
provide such services but in no event in excess of the quantity of, or in kind
other than, such services provided to the Contributed Business prior to the
Asset Transfer Effective Time. In addition, for two years from the date hereof,
the Retained Business shall have the right to purchase services from the
Partnership at full cost and otherwise on arms'-length terms, in all cases where
it is reasonable under all the circumstances for the Partnership to provide such
services. In no event, however, shall this Section 1.9 override the express
terms and conditions of a Related Agreement as to particular services.

                                    SECTION 2
                  REPRESENTATIONS AND WARRANTIES OF CONTRIBUTOR
                  ---------------------------------------------

         Except as set forth on Schedule 2, Contributor and Geon LP jointly and
severally represent and warrant to the Partnership as follows:

         2.1   EMPLOYEE BENEFITS.

         (a) Schedule 2.1 contains a true and complete list of each bonus,
deferred compensation, incentive compensation, stock purchase, stock option,
employment, consulting, severance or termination pay, hospitalization or other
medical, life or other insurance, supplemental unemployment benefits,
profit-sharing, pension or retirement plan, program, agreement or arrangement,
and each other "employee benefit plan" (within the meaning of section 3(2) of
ERISA), program, agreement or arrangement, whether formal or informal, written
or oral, and whether legally binding or not, sponsored, maintained or
contributed to or required to be contributed to by Contributor or by any trade
or business, whether or not incorporated, that, together with Contributor, would
be deemed a "single employer" within the meaning of section 4001(b)(1) of ERISA,
a "controlled group" within the meaning of section 414(b) of the Code, "trades
or businesses under common control" within the meaning of section 414(c) of the
Code, or an "affiliated service group" 

                                      -11-
<PAGE>   16

within the meaning of section 414(m) of the Code (an "ERISA Affiliate") within
the last three years, for the benefit of any employee, former employee,
consultant, officer, or director of Contributor or its Affiliates (collectively,
the "Plans"). Neither Contributor nor any ERISA Affiliate has any plan or
commitment, whether legally binding or not, to create any additional Plan or to
modify or change any existing Plan that would affect any employee or terminated
employee of Contributor or any ERISA Affiliate. There has been no merger,
consolidation, or transfer of assets or liabilities (including any spinoff,
split up or split off) with respect to any of the ERISA Plans.

         (b) With respect to each of the Plans, neither Contributor nor any
ERISA Affiliate is obligated to continue with any such Plan beyond the Asset
Transfer Effective Time.

         (c) To the extent necessary or appropriate for the proper operation and
administration of each of the Plans, the participant and beneficiary records of
each Plan accurately state the history of each participant and beneficiary in
connection with such Plan and accurately states the benefits earned and owed to
each person under such Plan.

         (d) To the Knowledge of Contributor, each of the Plans is, and has
always been, operated in all respects in accordance with all Legal Requirements,
and all persons who participate in the operation of such Plans and all Plan
"fiduciaries" (within the meaning of section 3(2) of ERISA) have always acted in
accordance with the provisions of all Legal Requirements, the Plan documents and
written descriptions of the Plans. Each of the Plans intended to be "qualified"
within the meaning of section 401(a) of the Code is so qualified and has
received a currently applicable favorable determination letter, and nothing has
occurred since the date of such letter that could reasonably be expected to
cause the loss of such qualification.

         (e) No liability under Title IV of ERISA has been incurred, directly or
indirectly, by Contributor or any ERISA Affiliate since the effective date of
ERISA that has not been satisfied in full, and no condition exists that presents
a material risk to Contributor or an ERISA Affiliate of incurring liability
under such Title, other than a liability for premiums due the Pension Benefit
Guaranty Corporation ("PBGC"), which payments have been or will be made when
due. To the extent that this representation applies to sections 4064, 4069 or
4204 of Title IV of ERISA, it is made not only with respect to ERISA Plans but
also with respect to any employee benefit plan, program, agreement or
arrangement subject to Title IV of ERISA to which Contributor or an ERISA
Affiliate made, or was required to make, contributions during the three year
period ending on the last day of Contributor's most recent fiscal year.

         (f) The PBGC has not instituted any Proceedings to terminate any of the
ERISA Plans, and no condition exists that presents a material risk that any such
Proceedings will be instituted.

         (g) No reportable event within the meaning of section 4043 of ERISA, or
prohibited transaction within the meaning of section 406 of ERISA, has occurred
with respect to any Plan.

         (h) Neither Contributor, any ERISA Affiliate, any of the ERISA Plans or
any trust created thereunder nor any trustee or administrator thereof has
engaged in any transaction or has taken or failed to take any action in
connection with which Contributor, any ERISA Affiliate, any of the ERISA Plans,
any such trust, any trustee or administrator thereof, or any party dealing with

                                      -12-
<PAGE>   17


the ERISA Plans or any such trust could be subject to any liability, fine,
penalty, tax or related charge under section 409, section 502(c)(i) or (1), or
section 4071 of ERISA or Chapter 43 of the Code, or the imposition of a lien
pursuant to section 401(a)(29) or 412(n) of the Code. Each welfare plan of
Contributor or any ERISA Affiliate that is subject to section 1862(b)(1) of
Social Security Act has been operated in compliance with the secondary payor
requirements of such section.

         (i) No assets of any of the Plans are invested, directly or indirectly,
in real or personal property used by Contributor or, with respect to the ERISA
Plans, any ERISA Affiliate. There is sufficient liquidity of assets in each of
the funded Plans to promptly pay for the benefits earned and other liabilities
owed under such Plan. With respect to each of the Plans, no insurance contract,
annuity contract, or other agreement or arrangement with any financial or other
organization would impose any penalty, discount or other reduction on account of
the withdrawal of assets from such organization or the change in the investment
of such assets.

         (j) No Plan is a "multiemployer plan" as such term is defined in
section 3(37) of ERISA. No Plan is a plan maintained by more than one employer
(a so-called "multiple employer plan") for purposes of section 413(c) of the
Code.

         (k) No amounts payable under the Plans or any other agreement or
arrangement to which Contributor or any ERISA Affiliate is a party will, as a
result of the transactions contemplated by this Agreement, fail to be deductible
for federal income tax purposes by virtue of section 280G of the Code.

         (l) No "leased employee," as that term is defined in section 414(n) of
the Code, performs services for Contributor or any ERISA Affiliate.

         (m) No Plan provides benefits, including death or medical benefits
(whether or not insured), with respect to current or former employees after
retirement or other termination of service other than (i) coverage mandated by
applicable law, (ii) death benefits or retirement benefits under any "employee
pension plan," as that term is defined in section 3(2) of ERISA, (iii) deferred
compensation benefits accrued as liabilities on the books of Contributor or the
ERISA Affiliates, or (iv) benefits, the full cost of which is borne by the
current or former employee (or his beneficiary).

         (n) With respect to each Plan that is funded wholly or partially
through an insurance policy, there will be no liability of Contributor or an
ERISA Affiliate, as of the Closing Date, under any such insurance policy or
ancillary agreement with respect to such insurance policy in the nature of a
retroactive rate adjustment, loss sharing arrangement or other actual contingent
liability arising wholly or partially out of events occurring prior to the
Closing Date.

         (o) There is, and has been, no actual, and to the Knowledge of
Contributor, no anticipated, threatened or expected, litigation or arbitration
concerning or involving any of the Plans. No complaints to or by any Authority
have been filed, or, to the knowledge of Contributor, are threatened or
expected, with respect to any of the Plans. No claims have been made, or, to the
Knowledge of Contributor, are expected, with respect to any bond or any
fiduciary or other similar insurance with regard to the actions of any Person in
connection with any of the ERISA Plans or other funded Plans, nor has there
been, nor is there, to the Knowledge of Contributor, expected, any 


                                      -13-
<PAGE>   18


notice to any insurer under any such bond or policy with regard to any of such
Plans. No application for any bond or fiduciary liability or similar insurance
policy has been issued subject to any qualification, condition or exclusion.

         (p) Except as provided in this Agreement, the consummation of the
transactions contemplated by this Agreement will not (i) entitle any current or
former employee or officer of Contributor or any of its Affiliates to severance
pay, unemployment compensation or any other similar payment, (ii) accelerate the
time of payment or vesting, or increase the amount of, any compensation due to
any such employee or officer, (iii) result in any employment-related expenses or
liabilities, the full cost of which will not be paid by Contributor, or (iv)
result in any prohibited transaction described in section 406 of ERISA or
section 4975 of the Code for which an exemption is not available.

         2.2   LABOR RELATIONS.

         (a) As related to the Contributed Business, (i) there are no collective
bargaining agreements or other similar agreements, arrangements or undertakings,
written or oral, with employees as a group to or by which Contributor is a party
or is bound, (ii) no employees of Contributor are represented by any labor

         (b) As related to the Contributed Business, Contributor is in
compliance in all material respects with all Legal Requirements pertaining to
labor, employment and employment practices and wages, hours, and other terms and
conditions of employment, with respect to Contributor employees, including each
Legal Requirement pertaining to equal opportunity, discrimination, immigration,
promotion or pay of employees, wages, hours of work, family or medical leaves of
absence, plant closings and layoffs, collective bargaining, occupational safety
and health, unemployment, and ERISA. There is no pending, or to the Knowledge of
Contributor, threatened, Proceeding by or before the National Labor Relations
Board, the Equal Employment Opportunity Commission, the Department of Labor or
any other Authority in connection with any current, former or prospective

         (c) As related to the Contributed Business, Contributor (i) has
withheld all amounts required by Legal Requirements or by agreement to be
withheld from the wages, salaries and other payments to Employees, (ii) is not
liable for any arrears of wages, (iii) is not delinquent with respect to any

compensation benefits, workers' compensation, social security, or other benefits
for Employees, and (iv) is not liable for any Taxes, fines, or penalties, or

Proceeding for the failure (or alleged failure) to comply with any of the
foregoing.

         2.3   TITLE TO ASSETS; ABSENCE OF LIENS AND ENCUMBRANCES; LEASES.

         (a) Each of Contributor and Contributed Subsidiary has good and
marketable title to all of its Fee Interests, free and clear of all
Encumbrances, except (i) any prior reservations, rights of way, easements and
other matters of record to the extent valid, subsisting and affecting the
Assets, (ii) any prior unrecorded easements set forth in a written instrument or
agreement for which permanent 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, (vi) such imperfections of title
or 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, and (vii) any matters disclosed by surveys obtained in
connection with the transactions contemplated by this Agreement.

         (b) Each of Contributor and Contributed Subsidiary 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 of the permanent 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 set forth in a written
instrument or agreement for which permanent improvements have been constructed
in such a manner as to be apparent to the Partnership from inspection of the

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, (vi) such imperfections of
title or 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

and (vii) any matters disclosed by surveys obtained in connection with the
transactions contemplated by this Agreement. Neither Contributor nor any
Affiliate thereof has received from or delivered to the lessors under such
Leases any written notice of termination or threat of termination of such
respective Leases. True and complete copies of all written lease agreements
(including any written amendments, modifications or assignments thereof)
constituting, or evidencing the terms of, such Leases 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 Leases, 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). Contributor and its Affiliates have not received any written notice from
any lessor under any Lease, that any material

                                      -15-

<PAGE>   20

default or event of default on the part of Contributor or such Affiliate, as
lessee, under the provisions of any Leases, 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 Contributor or any such Affiliate, as lessee,
has occurred (which default or event of default has not been cured). To
Contributor's Knowledge, no material default or event of default on the part of
the lessor under the provisions of any of such Leases, 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) Contributor or its Affiliates have good title to all of the
personal property constituting Assets (other than the Contributed Intellectual
Property) owned or 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.

         (d) No Asset is burdened by (i) an Encumbrance that secures an
obligation that is of such a nature that, after the consummation of the
transactions contemplated by this Agreement, (A) will be binding upon or
applicable to a Person other than the Partnership or (B) in the event of a
breach of such obligation by a Person other than the Partnership, would cause
such Asset to be foreclosed upon or otherwise taken from the Partnership or (ii)
an Encumbrance that secures Indebtedness.

         2.4 TITLE MATTERS; DEFECTS IN IMPROVEMENTS. To Contributor's Knowledge,
there are no trespassers or other adverse parties in possession on or affecting
the Fee Interests, the Leased Premises or the Leaseholds of Contributor or any
of its Affiliates that would reasonably be expected to have a Material Adverse
Effect. Contributor and its Affiliates have not granted and none of the
foregoing is party to any unrecorded options, rights of refusal, sales contracts
or other such contractual rights to acquire such Fee Interests, Leased Premises
or Leaseholds in favor of any third parties relating to its Fee Interests,
Leased Premises or Leaseholds. No written notice has been received by
Contributor or any of its Affiliates (i) from any insurance company or any
Authority with respect to its Fee Interests, Leased Premises or Leaseholds 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 permanent improvements situated thereon (in each case, which
have not been cured) or (ii) from any other Person making an adverse claim
against the Assets.

         2.5 WORKING CAPITAL. Including for this purpose the Specified Working
Capital Items, (a) Contributor has operated the Contributed Business in the
ordinary course of business from June 24, 1998 to the Asset Transfer Effective
Time such that its Inventory, Stores Inventory, Prepaid Expenses, Accounts
Receivable and Trade Accounts Payable, as of the Asset Transfer Effective Time,
are at substantially the same level as would have existed for Contributor
without regard to the transactions contemplated by the Master Transaction
Agreement, and (b) the level of Working Capital of Contributor as of the Asset
Transfer Effective Time is reasonably sufficient to operate the Contributed
Business consistent with current and historical practices.

         2.6 GOVERNMENT LICENSES, PERMITS AND RELATED APPROVALS. The Government
Licenses constitute all those necessary for the normal operation and conduct of

the failure to have such Government Licenses would not reasonably be expected to
have a Material Adverse Effect.

         2.7 ALL NECESSARY ASSETS. Including for this purpose the Excluded
Railcars, the Assets together with the rights under this Agreement and 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.

         2.8 CONDUCT OF BUSINESS IN COMPLIANCE WITH REGULATORY AND CONTRACTUAL
REQUIREMENTS. Contributor and its Affiliates are operating and conducting the
Assets and 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.

         2.9 LEGAL PROCEEDINGS. Schedule 2.9 contains a complete and accurate

a party and involving the Assets. There is no Proceeding to which Contributor or

not yet due and payable) upon the Assets.

for any Taxes.

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

adverse effect on the ability of the Partnership to perform its obligations
hereunder or under the Assignment and Assumption Agreements.

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

Agreement and the Related Agreements by the Partnership and the consummation by
it of the transactions contemplated hereby and thereby (i) will not require any

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
Limited 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

pursuant to this Agreement.

         5.2   INDEMNIFICATION.

         (a) Subject to the other provisions of this Section 5, Contributor
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 such indemnitees arising out of, in
connection with or relating to:

                  (i) Any misrepresentation in or breach of the representations
         and warranties of Contributor 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 is not a breach of the warranties in this
         Agreement shall not be indemnified against pursuant to this Section 5;

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

                  (iii) Any obligation or liability relating to the Excluded
         Assets;

                  (iv)  Any Exposure Claim;

                                      -22-
<PAGE>   27

                  (v) Any Product Exposure Claim that is not an Assumed
         Liability;

                  (vi) Any HSE Claim that is related to a Pre-Closing Liability
         and that is not an Assumed Liability;

                  (vii) Any Third Party Claim (other than Exposure Claims,
         Product Exposure Claims and HSE Claims) that is related to a
         Pre-Closing Liability and that is not an Assumed Liability;

                  (viii) Any obligation (A) for the payment of severance
         benefits to employees of Contributor or any of its Affiliates except as
         set forth in Section 1.7, (B) attributable to Contributor's or any of
         its Affiliates' employment of any employee, agent or independent
         contractor prior to the Asset Transfer Effective Time or (C) assumed by
         Contributor and its Affiliates pursuant to Section 1.7;

                  (ix) Any Taxes of Contributor, Contributed Subsidiary, Canco
         1, Canco 2 or Geon LP for any taxable period or portion thereof ending
         before the Asset Transfer Effective Time or arising from any of the
         transactions contemplated by this Agreement, except to the extent
         otherwise provided in Sections 6.2(c) and (d); or

                  (x) any Proceeding instituted or asserted against the
         Partnership by any Person (A) that arises, directly or indirectly, as a
         result of the parcels identified as "Assigned Area C" and "Assigned
         Area D" on the survey of Contributor's Pedricktown, New Jersey facility
         (collectively, the "Parcels") not being owned by Contributor, but
         instead being owned by B.F. Goodrich Company or (B) to prevent,
         prohibit, or place a material restriction upon the Partnership from
         utilizing the Parcels in connection with its operation of the
         Contributed Business.

PROVIDED, HOWEVER, that the following provisions shall apply to the
indemnification obligations of Contributor:

                  (A) Contributor, in the aggregate, shall not have any
         indemnification obligation under clause (i) above for any individual
         Liability (I) unless the amount of such Liability exceeds $100,000 (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)
         and (II) until the total of all Liabilities under said clause (i)
         equals an aggregate deductible of $500,000 (the "Deductible") (after
         which point, subject to clause (I) above, Contributor will be obligated
         to indemnify the Partnership and the other indemnitee against such
         further Liabilities); and 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 and
         Deductible 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


                                     -23-
<PAGE>   28

         Partnership and the other indemnitee shall be entitled to indemnity
         relating back to the first dollar, subject to the Individual Basket and
         Deductible); and PROVIDED, FURTHER, that this clause (A) shall not be
         applicable to a misrepresentation in or a breach of the representations
         and warranties in Section 2.3(d)(ii).

                  (B) If Contributor is indemnifying against a particular
         Liability under two or more of clauses (i) - (x) above, the Partnership
         and the other indemnitee shall have the right to select the clause or
         clauses under which they seek indemnification; PROVIDED, that the
         aggregate indemnification shall in no event exceed the amount of the
         particular Liability.

         (b) NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT, TO THE
FULLEST EXTENT PERMITTED BY LAW, EXCEPT FOR CLAIMS ARISING SOLELY UNDER SECTION
5.2(a)(x), NEITHER CONTRIBUTOR NOR ANY OF ITS AGENTS, EMPLOYEES, REPRESENTATIVES
OR AFFILIATES SHALL BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL, INDIRECT, PUNITIVE,
EXEMPLARY, SPECIAL OR OTHER SIMILAR 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 CONTRIBUTOR OR ANY OF ITS
AFFILIATES. 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 this Section 5 to the contrary,
it is expressly agreed that Contributor shall not be required to indemnify the
Partnership and the other indemnitee for any Liability arising out of, in
connection with or related to any HSE Claim to the extent that the action,
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 an action, condition, event, circumstance or other basis for an HSE
Claim by reason of the continuance thereof after the Asset Transfer Effective
Time (i) under circumstances where the Partnership does not know of its
existence and has not breached any affirmative 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. By way of example,
and not by way of limitation, the following actions by the Partnership shall not
be deemed to be exacerbation or acceleration of any HSE Claim or any condition,
event, circumstance or other basis therefor:

                           (A) any action required to comply with Legal
                  Requirements or with any Contracts with third parties;

                                      -24-
<PAGE>   29

                           (B) any action that, in the Partnership's reasonable
                  judgment, is necessary to be taken in emergencies or in order
                  to protect human health and safety from any imminent and
                  substantial endangerment;

                           (C) any investigation, or any report to any
                  Authority, directly resulting from repair or maintenance
                  activities necessary to the continued operation of the Assets
                  or from the replacement, relocation, demolition, closure or
                  expansion of buildings, structures, fixtures or other
                  improvements on or appurtenant to the Fee Interests or the
                  Leaseholds (where there was no reasonably practicable
                  alternative, in the reasonable judgment of the Partnership, to
                  effecting such replacement, relocation, demolition, closure or
                  expansion in the place and manner in which it was effected),
                  which investigation or report is required pursuant to HSE
                  Laws, including waste classification or characterization and
                  reports of Releases or the presence of Chemical Substances, if
                  such discovery is made in the ordinary course of such
                  activities;

                           (D) periodic compliance or management system audits
                  conducted in the ordinary course of business, including any
                  OSHA Star or IS 14000 audits;

                           (E) responding to an inquiry, inspection, request for
                  information or other communication from an Authority,
                  regardless of whether a subpoena or other Legal Requirement
                  mandates a response;

                           (F) responding to an inquiry, request for information
                  or other communication from a third party, regardless of
                  whether a subpoena or other Legal Requirement mandates a
                  response, and providing information to a community advisory
                  panel or the public;

                           (G) filing or processing applications for issuance,
                  renewal, modification, amendment or termination of Government
                  Licenses and providing information to an Authority or other
                  third party in connection therewith; or

                           (H) participating in or communicating with a group of
                  potentially responsible parties involved in a Remedial Action,
                  regardless of whether a subpoena or other Legal Requirement
                  mandates such participation or communication, if the
                  Partnership believes in good faith that such participation or
                  communication may reduce any Liability associated with such
                  Remedial Action.

         (d) Subject to the other provisions of this Section 5, the Partnership
hereby indemnifies, to the fullest extent permitted by applicable law,
Contributor and its Affiliates, officers, directors and employees against and
agrees to hold each of them harmless from any and all Liability incurred or
suffered by such indemnitee 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


                                      -25-

         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, PUNITIVE, EXEMPLARY, SPECIAL OR OTHER SIMILAR 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) NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT, CONTRIBUTOR
AND GEON LP MAKE NO REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, AND THERE
ARE NO EXPRESS OR IMPLIED CONDITIONS, AS TO THE FOLLOWING MATTERS: THE
MAINTENANCE, REPAIR, DESIGN OR MARKETABILITY OF THE TANGIBLE PERSONAL PROPERTY
AND FIXTURES THAT CONSTITUTE PART OF THE CONTRIBUTED BUSINESS OR ASSETS,
INCLUDING ANY REPRESENTATION OR WARRANTY AS TO MERCHANTABILITY OR FITNESS FOR
ANY PARTICULAR PURPOSE OF SUCH TANGIBLE PERSONAL PROPERTY AND FIXTURES, IT BEING
EXPRESSLY UNDERSTOOD AND AGREED BY THE PARTIES HERETO THAT THE PARTNERSHIP SHALL
BE DEEMED TO BE OBTAINING RIGHTS IN SUCH TANGIBLE PERSONAL PROPERTY AND FIXTURES
IN THE PRESENT STATE OF REPAIR OF SUCH TANGIBLE PERSONAL PROPERTY AND FIXTURES,
"AS IS, WHERE IS, AND WITH ALL FAULTS."

         (g) The rights provided to each Indemnified Party pursuant to this
Section 5, as limited by and subject to the provisions of this Section 5, 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, or arising in
connection with or related in any way to the subject matter of this Agreement or
such agreements. Each Indemnified Party 

                                      -26-
<PAGE>   31


hereby waives and relinquishes any other rights, remedies, causes of action or
other claims in respect of any such breach, including equitable and common law
rights and rights created by statute, that such Indemnified Party would
otherwise have for any such breach or with respect to this Agreement or such
agreements or any Liability arising from, in connection with or related to the
subject matter of this Agreement, including any such Liability arising from, in
connection with or related to HSE Laws.

         5.3   PROCEDURES.

         (a) Any Person seeking indemnification under Section 5.2 (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 6.8.

         (b) If an Indemnified Party is notified of a Third Party Claim that 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 5 except to the
extent that such failure prejudices or impairs, in any material respect, any of
the rights or obligations of the Indemnifying Party.

         (c) Any Indemnifying Party may, and at the request of the Indemnified
Party shall, participate in and control the defense of the Third Party Claim
with counsel of its choice reasonably satisfactory to the Indemnified Party. The
Indemnified Party shall have the right to employ separate counsel in any such
action and to participate in the defense thereof, but the fees and expenses of
such counsel shall be at the expense of the Indemnified Party unless (i) the
employment thereof has been specifically authorized in writing by the
Indemnifying Party, (ii) the Indemnifying Party failed to assume the defense and
employ counsel or failed to diligently prosecute or settle the Third Party Claim
or (iii) there shall exist or develop a conflict that would ethically prohibit
counsel to the Indemnifying Party from representing the Indemnified Party. If
requested by the Indemnifying Party, the Indemnified Party agrees to cooperate
with the Indemnifying Party and its counsel in contesting any Third Party Claim
that the Indemnifying Party elects to contest, including by making any
counterclaim against the Person asserting the Third Party Claim or any
cross-complaint against any Person, 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 

                                      -27-
<PAGE>   32

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; and PROVIDED FURTHER that the Indemnifying Party will
not, without the written consent of the Indemnified Party, consent to the entry
of any judgment or enter into any settlement that (A) does not provide for the
unconditional written release of, or final resolution of, Liability of the
Indemnified Party with respect to such Third Party Claim, or (B) places any
obligations, other than payment obligations fully indemnified by the
Indemnifying Party under this Agreement, on the Indemnified Party or on or
relating to the Assets. 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 Section 5.3(a) or (b), or if the Indemnifying Party
assumes the defense of the Indemnified Party pursuant to Section 5.3(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, including interest from the date any sum is so
expended by the Indemnified Party at a rate calculated pursuant to Section
13.16(b) of the Limited Partnership Agreement of the Partnership (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; and PROVIDED FURTHER, that the Indemnified Party will
not, without the written consent of the Indemnifying Party, consent to the entry
of any judgment or enter into any settlement that (i) does not provide for the
unconditional written release of, or final resolution of, Liability of the
Indemnifying Party with respect to such Third Party Claim, or (ii) places any
obligations, other than payment obligations fully indemnified by the
Indemnifying Party under this Agreement, on the Indemnifying Party or on or
relating to the Assets. 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 5.3, if the
Indemnifying Party disputes its potential liability to the Indemnified Party
under this Section 5.3 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
5.3 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, together with
interest as provided in Section 5.3(d).

         (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 5, the Indemnifying Party shall pay or cause to be paid
to the Indemnified Party the amount of the Liability 

                                      -28-
<PAGE>   33

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 or on behalf of the Indemnified Party.

         (g) In the event a Third Party Claim is brought in which both the
Partnership and Contributor are alleged to be liable or the liability as between
the Partnership and Contributor is alleged to be joint, or in which the
entitlement to indemnification under this Section 5 has not been determined, the
Partnership and Contributor shall cooperate in the joint defense of such Third
Party Claim and shall offer to each other such assistance as may reasonably be
requested in order to ensure the proper and adequate defense of any such matter.
Such joint defense shall be under the general management and supervision of the
party that 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 5, the other party
shall reimburse the party entitled to indemnification for all of its costs
incurred in connection with such defense.

         5.4 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, but only to the extent of any such payment. The Indemnified
Party shall cooperate with the Indemnifying Party in any reasonable manner in
prosecuting any subrogated claim.

         5.5 CLAIMS FOR HSE REMEDIAL ACTION. This Section 5.5 shall govern the
interpretation of the indemnification obligations under Sections 5.2(a)(vi) and
5.2(d)(iii) in respect of any HSE Claim requiring the performance of
investigatory, removal or remedial work, correction of noncompliance or other
corrective action (but not the payment of money other than to third parties
performing such investigatory, removal or remedial work, correction of
noncompliance or other corrective action) by or on behalf of the Partnership or
Contributor ("Remedial Action") for which the Partnership or Contributor,
respectively, may seek indemnification (an "HSE Remedial Action Claim") from the
other, regardless of whether such HSE Claim is an HSE Type A Claim or an HSE
Type B Claim. Notwithstanding the other provisions of this Section 5:

         (a) In the case of an HSE Remedial Action Claim, the Partnership shall
have the right to conduct and control such Remedial Action; PROVIDED, that the
Partnership provides Contributor with the opportunity to: (i) review and comment
to the Partnership upon any significant work plans for such Remedial Action
prior to finalization and implementation; (ii) attend meetings with Authorities
concerning such Remedial Action, PROVIDED that the Partnership will control the
negotiations with any Authorities during such meetings; and (iii) have a
representative present during the performance of such Remedial Action.

<PAGE>   34

         (b) Contributor and the Partnership agree that Contributor shall have
no obligation pursuant to Section 5.2(a)(vi) to indemnify against any HSE
Remedial Action Claim unless the Remedial Action for which the Partnership is
seeking indemnification was or will be undertaken as a result of the
Partnership's discovery or receipt of notice of (i) with respect to an HSE Type
B Claim, any noncompliance with HSE Laws, (ii) with respect to an HSE Type A
Claim, the presence, Release or threatened Release of Chemical Substances on or
before the Asset Transfer Effective Time at levels in excess or in contravention
of any applicable level or standard of any HSE Law applicable to such Remedial
Action or any levels set forth in the EPA Region III Risk-Based Concentration
Table (or any replacement or modification thereof) for water, ambient air or
soil (as applicable) as in effect on the date of such Remedial Action
(collectively, the "Threshold Level"), (iii) with respect to an HSE Type A
Claim, any requirement of any HSE Law or any agreement with a third party who
has asserted an HSE Claim, or (iv) any imminent and substantial endangerment to
human health and safety.

         (c) Contributor and the Partnership agree that any Remedial Action to
be undertaken pursuant to this Section 5.5 for which either party may seek
indemnification shall: (i) be the Lowest Cost Response under the circumstances
and based on the assumption that the Fee Interests and the Leaseholds are and
will continue to be used for industrial (as opposed to residential) purposes,
unless (A) any HSE Law applicable to such Remedial Action requires a different
land use assumption (e.g., residential) or (B) the Lowest Cost Response would
result from a different land use assumption; (ii) not, unless required to
achieve the Lowest Cost Response, exceed the least stringent requirements of all
HSE Laws and agreements with third parties who have asserted an HSE Claim; and
(iii) be conducted and completed in compliance in all material respects with all
HSE Laws. To the extent that the Partnership elects to exceed the Lowest Cost
Response in undertaking a Remedial Action that is the subject of an HSE Remedial
Action Claim, Contributor's obligation under Section 5.2(a)(vi) shall be limited
to the Lowest Cost Response, and the Partnership shall be responsible for any
costs associated with exceeding the Lowest Cost Response.

         (d) Each of Contributor and the Partnership agrees that it shall not
solicit or importune any Authority to require any Remedial Action for which it
may seek indemnification unless (i) required by any HSE Law or agreement with a
third party who has asserted an HSE Claim, (ii) an HSE Law or Threshold Level
has been contravened or exceeded or (iii) such Remedial Action, in the
Partnership's reasonable judgment, is necessary in order to protect human health
and safety from any imminent and substantial endangerment, PROVIDED, that in the
event a Threshold Level has been contravened or exceeded, the Partnership may
undertake any Remedial Action under any applicable self-directed or voluntary
cleanup program. Nothing in this Section 5 shall prevent Contributor or the
Partnership from reporting any noncompliance or potential noncompliance with any
HSE Law, or any Release, threatened Release or the discovery or presence of any
Chemical Substance to any Authority, or from seeking written approval or
certification from such Authority that Contributor or the Partnership has
completed any Remedial Action regarding an HSE Remedial Action Claim, if, in
each case, Contributor or the Partnership believes in good faith that such
reporting is (A) required by any HSE Law or any agreement with a third party who
has asserted an HSE Claim, (B) necessary to achieve the Lowest Cost Response or
(C) necessary to receive immunity or penalty mitigation under any HSE Law,
including the U.S. Environmental Protection Agency's Incentives for
Self-Policing: Discovery, Disclosure, Correction and Prevention of Violations
dated December 22, 1995, as it may be amended from time to time; PROVIDED, that
Contributor's obligation under 

                                      -30-
<PAGE>   35


Section 5.2(a)(vi) or the Partnership's obligation under Section        
5.2(d)(iii) in connection with any Remedial Action resulting from any notice
described in clause (C) shall be limited to the Lowest Cost Response.

         (e) Contributor and the Partnership shall promptly notify the other
party of any action, condition, event or circumstance that may be subject to
Remedial Action under this Section 5.5 for which either party may seek
indemnification upon receipt of any written document concerning such matter.
Contributor and the Partnership shall promptly notify the other party of any
Release or threatened Release of Chemical Substances or other action, condition,
event or circumstance that such party believes may adversely impact a Remedial
Action after any such matter comes to such party's attention, PROVIDED, that
failure to so notify shall not affect the rights of an Indemnified Party except
to the extent that an Indemnifying Party is actually prejudiced as a result of
such delay. The Partnership shall develop and administer its standards and
practices for determining whether to undertake Remedial Action and, if
undertaken, how to carry out Remedial Action, so that comparable circumstances
or conditions existing at its various properties and facilities are managed in a
comparable way, regardless of whether or not the Partnership acquired such
properties and facilities from Contributor.

         (f) Contributor and the Partnership agree to consult with each other in
connection with any Remedial Action subject to indemnification under this
Section 5. If so requested by the other party, Contributor or the Partnership,
as the case may be, shall provide the requesting party with (i) any material
correspondence, reports, technical data or other material written information
generated regarding such Remedial Action, (ii) reasonable access to the
properties and to employees, books and records related to such Remedial Action,
and (iii) the right to take split samples, in each case for the purpose of
verifying the performance of any Remedial Action, the costs for which Remedial
Action Contributor is required to indemnify the Partnership pursuant to this
Section 5. Contributor and the Partnership agree that they shall maintain in
strict confidence, and in accordance with any confidentiality or joint defense
agreements then in effect between the Partnership and Contributor, any of the
foregoing information that is non-public and confidential and any other
confidential information concerning any HSE Remedial Action Claim, subject to
disclosure required by Legal Requirements. If either party is required to
disclose any such non-public, confidential information as a result of any Legal
Requirement, such party will promptly notify the other party and will give such
other party the opportunity to review and comment in advance upon the content
and timing of any such disclosure. The Partnership shall submit any
reimbursement request for indemnification pursuant to this Section 5 to
Contributor and Contributor shall pay the amount requested in such reimbursement
request within 30 days of receipt thereof. If Contributor objects to any portion
of such reimbursement request, it shall notify the Partnership in writing of
such objection with ten days of receipt thereof, and shall pay the undisputed
portion as set forth in the previous sentence. Any dispute regarding any
reimbursement request shall be resolved pursuant to the dispute resolution
procedures set forth in Appendix B.

         (g) Upon performance of a Remedial Action subject to indemnification
pursuant to this Section 5.5, the party conducting such Remedial Action (the
Partnership or Contributor, as applicable), shall use commercially reasonable
efforts to obtain written documentation, approval or certification of such
completion. The obligation of Contributor in respect of a particular HSE
Remedial Action Claim shall cease when: (i) with respect to a Remedial Action
involving an HSE 

                                      -31-
<PAGE>   36

Type A Claim over which an Authority has not asserted jurisdiction, the Remedial
Action has been completed, and any Chemical Substances for which the Threshold
Level was contravened or exceeded have been satisfactorily investigated, removed
or remediated, in accordance with HSE Laws, and the contractor conducting the
Remedial Action (on behalf of the Partnership or Contributor, as applicable)
provides a written certification reasonably satisfactory to the Partnership
confirming the completion of the Remedial Action in accordance with HSE Laws;
(ii) with respect to a Remedial Action involving an HSE Type A Claim over which
an Authority has asserted jurisdiction, the Remedial Action has been completed
in accordance with HSE Laws to the satisfaction of such Authority, and the
Authority has either (A) issued a written approval or certification of
completion of such Remedial Action that provides that no further action is
required or planned at a future date as of the time of such approval, but which
approval may be qualified or conditioned by the Authority with respect to the
accuracy or completeness of the data or information provided, the discovery of
new information, changes in land use which affect the Remedial Action or other
standard or model reservations of similar type or form in use by the Authority
at the time of such approval (an "Approval"), or (B) failed through inaction to
issue such Approval within one year of the submission of a written request by
the party conducting such Remedial Action for such Approval, without during this
one-year period rejecting approval or requesting further information or further
Remedial Action; (iii) with respect to a Remedial Action involving an HSE Type B
Claim over which an Authority has not asserted jurisdiction, the Remedial Action
has been completed in accordance with HSE Laws and the contractor conducting the
Remedial Action (on behalf of the Partnership or Contributor, as applicable)
provides a written certification reasonably satisfactory to the Partnership
confirming the completion of the Remedial Action in accordance with HSE Laws; or
(iv) with respect to a Remedial Action involving an HSE Type B Claim over which
an Authority has asserted jurisdiction, the Remedial Action has been completed
in accordance with HSE Laws and to the satisfaction of such Authority, and the
Authority has either (A) issued an Approval or (B) failed through inaction to
issue such Approval within one year of the submission of a written request by
the party conducting such Remedial Action for such Approval, without during this
one-year period rejecting approval or requesting further information or further
Remedial Action.

         (h) Completion of a Remedial Action shall not preclude Contributor or
the Partnership from asserting a subsequent HSE Remedial Action Claim that
arises from the same condition, event, circumstance or other basis that resulted
in the original Remedial Action (except with respect to the work completed in
such original Remedial Action); PROVIDED, that the Partnership shall be
responsible, pursuant to Section 5.2(d), if and to the extent that it
exacerbates or accelerates such subsequent HSE Remedial Action Claim as set
forth in Section 5.2(c); and PROVIDED, FURTHER, that the Partnership shall be
responsible for maintaining compliance with HSE Laws from and after the date on
which the correction of any noncompliance with HSE Laws is completed consistent
with Section 5.5(g).

         (i) Notwithstanding any other provision of this Agreement, Contributor
shall have the right to conduct and control all Remedial Action related to the
authorities and approvals necessary in order to consummate the transactions
contemplated hereby under the New Jersey Environmental Cleanup Responsibility
Act, including the New Jersey Industrial Site Recovery Act, including such
Remedial Action that occurs after the Closing Date. Such Remedial Action
conducted by the Seller shall not be subject to Section 5.5(c).

INDEMNIFICATION HEREUNDER IN ACCORDANCE WITH THE TERMS HEREOF, REGARDLESS OF

OF OR BY ANY SUCH INDEMNIFIED PARTY. THE PARTIES AGREE THAT THIS STATEMENT

         6.4 BINDING EFFECT; BENEFIT. Subject to Section 6.6, this Agreement
shall inure to the benefit of and be binding upon the parties hereto and their
respective permitted successors and assigns. Nothing in this Agreement,
expressed or implied, is intended to confer on any Person other than the parties
hereto and their Affiliates or their respective permitted successors and
assigns, any rights, remedies, obligations or liabilities under or by reason of
this Agreement.

         6.5 OCCASIONAL AND BULK SALES. To the extent applicable, the
Partnership and Contributor each agree to waive, to the fullest extent permitted
by law, compliance by the other with the provisions of the Bulk Sales Law of any
jurisdiction. Notwithstanding the foregoing, Contributor agrees to indemnify and
save harmless the Partnership from and against any Liability that may be made or
brought against the Partnership or that the Partnership may suffer or incur as a
result of, in respect of, or arising out of such non-compliance.

         6.6 ASSIGNABILITY. Neither this Agreement nor any of the rights or
obligations hereunder shall be assignable (by operation of law or otherwise) by
Contributor or Geon LP without the prior written consent of the Partnership or
shall be assignable (by operation of law or otherwise) by the Partnership
(except to a wholly-owned subsidiary thereof) without the prior written consent

of this Section shall be null and void.

         6.7 AMENDMENT; WAIVER. This Agreement may be amended, supplemented or
otherwise modified only by a written instrument executed by the parties hereto.
No waiver by any party of any of the provisions hereof shall be effective unless
explicitly set forth in writing and executed by the party so waiving. Subject to
the agreements and obligations of the Partnership hereunder or under applicable
Legal Requirements, no investigations by the Partnership heretofore or hereafter
made shall affect the representations and warranties of Contributor, and, except
as otherwise provided in Section 5.1, such representations and warranties shall
survive any such investigation. The waiver by any party hereto of a breach of
any provision of this Agreement shall not operate or be construed as a waiver of
any subsequent breach.

         6.8 DISPUTE RESOLUTION. All disputes under this Agreement shall be
resolved in accordance with the Dispute Resolution Procedures set forth in
Appendix B.

         6.9 SEVERABILITY. In the event that any provisions of this Agreement
shall finally be determined to be unlawful, such provision shall, so long as the
severance of such provision does not have a Material Adverse Effect on the
economic and legal substance of the transactions contemplated hereby as to
Contributor or the Partnership, be deemed severed from this Agreement and every
other provision of this Agreement shall remain in full force and effect.

         6.10 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original and all of which
together shall be deemed to be one and the same instrument.

         6.11 CONFLICT WITH TRANSFER DOCUMENTS. Notwithstanding anything to the
contrary contained in any Transfer Document, no remedy or claim shall be
available to any Person under or by reason of any Transfer Document or any terms
or warranties thereof, except to the extent, if any, 

                                      -36-
<PAGE>   41


such remedy or claim arises under this Agreement. In the event of any conflict

Document attached to this Agreement as an Exhibit, on the Closing Date, the
parties may, upon mutual agreement, execute and deliver revised forms of such
Transfer Documents or elect to not use any such Transfer Document.

                                   Appendix B

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


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

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

         (3) ADR AND BINDING ARBITRATION PROCEDURES. If a Dispute arises, the
following procedures shall be implemented:

         (a) Any party to this Agreement may at any time invoke the dispute
resolution procedures set forth in this Appendix B as to any Dispute by
providing written notice of such action to the other party or parties to the
Dispute, who within five business days after such notice shall schedule a
meeting to be held in Dallas, 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

                                      B-1
<PAGE>   55


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 Dallas, 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 New
York 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 receipt 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' costs 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, punitive, exemplary, special or other
similar 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 a party, the Arbitrator
must certify in the award that no indirect, consequential, incidental, punitive,
exemplary, special or other similar 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 

                                      B-2
<PAGE>   56

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.

         (g) In the event that a Dispute involving Remedial Action pursuant to
Section 5.5 is submitted to mandatory and binding arbitration, any factual or
technical dispute regarding the presence, Release or threatened Release of
Chemical Substances under Section 5.5(b)(ii) or the Lowest Cost Response under
Section 5.5(c)(i) or (ii) shall be submitted, either by the Arbitrator or by the
parties, to a nationally-recognized environmental consulting firm acceptable to
both parties for binding resolution of such factual or technical dispute, and
the Arbitrator shall be bound to accept and apply the factual or technical
findings of such firm in rendering its decision hereunder.

         (h) To assist the Arbitrator or the environmental consulting firm in
resolving Disputes where the Disputing Party alleges, pursuant to Section
5.3(g), and the Arbitrator and/or environmental consulting firm determines, that
both the Partnership and Contributor are liable for a Remedial Action, the
parties authorize the Arbitrator to allocate the Liability, as between
Contributor and the Partnership and for purposes of this Agreement only, based
upon the following rebuttable presumptions:

                  (i) with respect to an HSE Type A Claim involving a Remedial
         Action in, on, under, at, or in the vicinity of the Fee Interests or
         the Leaseholds, the Liability should be allocated based upon the
         relative years of use or operation by Contributor and the Partnership
         of the building, structure, fixture or improvement from which the
         Chemical Substance was Released;

                  (ii) with respect to an HSE Type A Claim involving a Remedial
         Action in, on, under, at or in the vicinity of an offsite treatment,
         storage or disposal facility, which facility received solid or
         hazardous waste or recyclable materials as a public or commercial
         enterprise and to which the Contributed Business is alleged to have
         sent or transported such materials for treatment, storage, recycling or
         disposal both before and after the Asset Transfer Effective Time, the
         Liability should be allocated based upon the relative volume of
         materials attributed to Contributor and its Affiliates and the
         Partnership, PROVIDED that the Chemical Substances attributed to the
         parties, and the constituents, toxicity, mobility and concentrations
         thereof, are similar in all material respects;

                  (iii) with respect to an HSE Type B Claim, the Liability to
         attain compliance with HSE Laws in effect as of the Asset Transfer
         Effective Time should be allocated solely to Contributor, while the
         Liability to attain compliance with HSE Laws that become more stringent
         after the Asset Transfer Effective Time and to continue to operate in
         compliance with then applicable HSE Laws should be allocated to the
         Partnership. To the extent penalties for noncompliance with HSE Laws in
         effect as of the Asset Transfer Effective Time are assessed for a
         period of time before the Asset Transfer Effective Time, before the
         Partnership knows of the existence of the noncompliance, or after the
         Partnership knows of the existence of such noncompliance but is taking
         commercially reasonable actions to cure the matter or to otherwise
         achieve compliance in a commercially reasonable and prudent matter,
         Liability in each case should be allocated solely to Contributor. To
         the extent 


                                       B-3
<PAGE>   57

         penalties for noncompliance with HSE Laws are assessed for a period of
         time after the Partnership knows of the existence of the noncompliance
         but has failed to take commercially reasonable actions to cure the
         matter or to otherwise achieve compliance in a commercially reasonable
         and prudent matter pursuant to Section 5.2(c), Liability should be
         allocated solely to the Partnership.

         (4) CONTINUATION OF BUSINESS. Notwithstanding the existence of any
Dispute or the pendency of any procedures pursuant to this Appendix B, 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.

                                (OXY VINYLS, LP)
                                ----------------


         This PARENT AGREEMENT (OXY VINYLS, LP) (this "Agreement") dated as of
the 30th day of April, 1999, is entered into among Occidental Chemical
Corporation, a New York corporation ("OCC"), The Geon Company, a Delaware
corporation ("Geon"), Occidental Petroleum Corporation, a Delaware corporation
("OPC"), and Oxy Vinyls, LP, a Delaware limited partnership (the "Partnership,"
and together with OCC, OPC and Geon, the "Parties", and each individually, a
"Party").

         WHEREAS, each of OCC and Geon is a "Parent" for purposes of this
Agreement; and

         WHEREAS, each of OPC and Geon is a "Subject Parent" for purposes of
this Agreement; PROVIDED, HOWEVER, that neither OPC nor Geon shall be a "Subject
Parent" from and after the expiration of 12 months from the date on which it and
its Affiliates no longer hold any Units in the Partnership; and

         WHEREAS, 1999 PVC Partner Inc., a Delaware corporation ("Geon Partner
Sub"), is a direct wholly-owned subsidiary of Geon; and

         WHEREAS, Occidental PVC, LLC, a Delaware limited liability company
("OCC GP"), and Occidental PVC LP, Inc., a Delaware corporation ("OCC LP" and,
together with OCC GP, the "OCC Partner Subs"), are both direct or indirect
wholly-owned subsidiaries of OCC; and OCC is an indirect wholly-owned subsidiary
of OPC; and

         WHEREAS, OCC and Geon entered into a Master Transaction Agreement,

         NOW THEREFORE, in consideration of the foregoing and the mutual
promises and covenants of the Parties, the Parties hereby agree as follows:

                                    SECTION 1
                     OWNERSHIP AND BUSINESS OF PARTNER SUBS
                     --------------------------------------

         1.1      RESTRICTIONS ON TRANSFER AND PLEDGE OF PARTNER SUB STOCK.

         (a) Each Parent agrees that, except as otherwise provided below in this
Section 1, or with the written consent of the other Parent, which consent may be
granted or withheld in such Parent's sole discretion, it will not, in any
transaction or series of transactions, directly or indirectly, (i) sell, assign
or otherwise dispose of, whether by act, deed, merger or otherwise ("Transfer")
or (ii) mortgage, pledge, encumber or create or suffer to exist any lien or
encumbrance upon or security interest in ("Pledge"), all or any part of the
capital stock or other equity interests (including any securities convertible
into or exchangeable for or carrying any rights to purchase, subscribe for or
otherwise acquire any such capital stock or other equity interests) of its
Partner Subs (collectively, the "Partner Sub Stock"). (Each of the defined terms
"Transfer" and "Pledge" is used herein both as a noun and as a verb.) Any
attempt by a Parent to Transfer or Pledge all or a portion of its Partner Sub
Stock in violation of this Agreement shall be void AB INITIO and shall not be
effective to Transfer such Partner Sub Stock or any portion thereof. The
Partnership Agreement contains provisions relating to the Transfer and Pledge of
the Partner Subs' direct interests in the Partnership.

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

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

         (c) Without the need for the consent of any Person and without the
application of the requirements of Section 1.2, each Parent may Transfer all
(but not less than all) of its Partner Sub Stock, if such Transfer is: (i) in
connection with (A) a merger, consolidation, conversion, share exchange or
Change of Control of such Parent or (B) a sale or other disposition by such
Parent of assets including the Partner Sub Stock where such Partner Sub Stock
constitutes less than 50% of the book value of the aggregate assets to be sold
or disposed of, as reflected on such Parent's most recent audited consolidated
(or combined) financial statements; (ii) to an 80%-Owned Affiliate of

                                       3

<PAGE>   5

such Parent; or (iii) to the shareholders of (A) such Parent, in the case of
Geon, or (B) OPC, in the case of OCC; PROVIDED, HOWEVER, that the requirements
of Section 1.2(d)(i)-(vi) must be satisfied in connection therewith. For
purposes of the preceding sentence, the term "Change of Control" shall (A) for
Geon be defined in the same way as that term is defined for Geon in Section 2.2
in its capacity as a Subject Parent and (B) for OCC mean an event or
circumstance that results in OCC's no longer being an Affiliate of OPC.

         (d) Except as provided in Section 1.1(c), nothing in this Agreement
shall prevent or restrict the Transfer or Pledge of the capital stock, equity
ownership interests or other securities of a Parent or any Person that owns a
direct or indirect interest in a Parent, and no such Transfer or Pledge of
securities issued by a Parent shall be deemed to constitute a Transfer or Pledge
of Partner Sub Stock hereunder.

         (e) Each Parent (so long as such Parent is performing its obligations
hereunder) may Pledge all (but not less than all) of its Partner Sub Stock in
connection with a loan to such Parent, PROVIDED that (i) the loan to such Parent
has been approved by the Partnership and (ii) the Pledge shall be evidenced by
an instrument, reasonably satisfactory to the Partnership, wherein, in the case
of the Partner Sub Stock of OCC GP and OCC LP, the lender receiving such Pledge
shall agree that in the event such lender obtains a right of foreclosure on
OCC's Partner Sub Stock, such lender will foreclose on the Partner Sub Stock of
OCC's Partner Subs proportionately so that such lender will in all events hold
portions of Partner Sub Stock of OCC GP and OCC LP proportionate to OCC's
holdings thereof.

         1.2      RIGHT OF FIRST REFUSAL AND RIGHT OF FIRST OPTION.

         (a) Without the consent of the other Parent, no Parent may Transfer
less than all of its Partner Sub Stock, and unless such Transfer is otherwise
permitted by Section 1.1, no Parent may Transfer its Partner Sub Stock, directly
or indirectly, for consideration other than cash. Unless such Transfer is
otherwise permitted by Section 1.1, any Parent (the "Selling Parent") that
receives a bona fide offer to purchase all of its Partner Sub Stock that it
desires to accept (an "Offer") or that otherwise desires to Transfer all of its
Partner Sub Stock to any Person shall give written notice (the "Initial Notice")
to the Partnership and the other Parent (the "Offeree Parent") stating that the
Selling Parent has received an Offer or otherwise desires to Transfer its
Partner Sub Stock and shall set forth the cash purchase price and all other
terms of the Offer or the cash purchase price (established as provided below)
and all other terms on which it otherwise is willing to sell its Partner Sub
Stock (in each case, the "Offer Terms"). In establishing the Offer Terms for a
proposed sale that does not involve an Offer, the Selling Parent shall obtain an
appraisal from an independent appraiser with a reasonable level of industry
experience of the cash price that a willing buyer under no compulsion to buy
would pay and a willing seller under no compulsion to sell would accept for the
Partner Sub Stock of the Selling Parent (the "Fair Market Value"). Delivery of
an Initial Notice shall constitute the irrevocable offer of the Selling Parent
to sell its Partner Sub Stock to the Offeree Parent hereunder.


                                       4
<PAGE>   6



         (b) The Offeree Parent shall have the option, exercisable by delivering
written notice (the "Acceptance Notice") of such exercise to the Selling Parent
within 60 days of the date of the Initial Notice, to elect to purchase all, but
not less than all, of the Partner Sub Stock of the Selling Parent on the Offer
Terms described in the Initial Notice. The Acceptance Notice shall set a date
for closing the purchase, such date to be not less than 30 nor more than 90 days
after delivery of the Acceptance Notice; PROVIDED, HOWEVER, that such time
period shall be subject to extension as reasonably necessary (up to a maximum of
an additional 120 days after such 90 day period) in order to comply with any
applicable filing and waiting period requirements under the Hart-Scott-Rodino
Antitrust Improvements Act (or any successor statute) or other Legal
Requirement. The closing shall be held at the Partnership's offices. The
purchase price for the Selling Parent's Partner Sub Stock shall be paid in
immediately available funds delivered at the closing, and all actions at the
closing shall conform in all material respects to the Offer Terms.

         (c) If the Offeree Parent does not elect to purchase all of the Selling
Parent's Partner Sub Stock within 60 days after the receipt of the Initial
Notice, the Selling Parent shall have a further 180 days during which it may,
subject to Section 1.2(d), consummate the sale of its Partner Sub Stock (i)
substantially in accordance with the terms of the Offer or (ii) if no Offer is
involved, to a third party purchaser on terms that are not substantially more
favorable to such purchaser than the Offer Terms and at a price equal to not
less than 90% of the Fair Market Value of the Partner Sub Stock. If the sale is
not completed within such further 180-day period, the Initial Notice shall be
deemed to have expired and a new notice and offer shall be required before the
Selling Parent may make any Transfer of its Partner Sub Stock. If the Selling
Parent receives a written offer during such further 180-day period from a third
party purchaser that is for less than 90% of the Fair Market Value, and the
Selling Parent is willing to accept the offer, then (1) the offer shall be
treated as an Offer, and (2) the Selling Parent must comply with the provisions
of this Section 1.2 before the Selling Parent may make any Transfer of its
Partner Sub Stock to the third party purchaser that made the Offer.

         (d) Notwithstanding the foregoing provisions of this Section 1.2,
except as provided in Section 1.1(c), a Parent may Transfer its Partner Sub
Stock only if all of the following occur:

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

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

                  (iii) The Transfer does not cause a default under any material
         contract (A) that has been approved unanimously by the Partnership
         Governance Committee and (B) to which the Partnership is a party or by
         which the Partnership or any of its properties is bound.

                  (iv) The Successor Parent executes an appropriate agreement to
         be bound by this Agreement.

                                       5
<PAGE>   7



                  (v) The transferor and transferee bear all reasonable costs
         incurred by the Partnership in connection with the Transfer.

                  (vi) The provisions of Section 1.2(e) are satisfied.

                  (vii) The Successor Parent must have sufficient resources to
         assume the obligations of the Parent, including any capital that may
         reasonably be expected to be requested from its Partner Subs by the
         Partnership under the then effective Strategic Plan, or the Successor
         Parent's obligations must be supported by a guarantee, letter of credit
         or other credit support reasonably satisfactory to the other Parent,
         and such Successor Parent must otherwise be reasonably acceptable to
         the other Parent.

         (e) OCC may Transfer the Partner Sub Stock of either of its Partner
Subs to any Person only if it simultaneously Transfers the Partner Sub Stock of
its other Partner Sub to such Person or a wholly-owned Affiliate of such Person.

         1.3 EFFECT OF TRANSFER. Upon completion of any Transfer that is
permitted hereunder, the Successor Parent shall succeed to and be substituted
for the applicable Parent, with the same effect as if it had been named herein,
and unless such Parent shall then be an Affiliate of such Successor Parent, such
Parent and its Affiliates shall thereupon be released from all obligations under
this Section 1 and Section 3. For purposes of this Section 1, the term
"Successor Parent" shall mean the acquiring, succeeding or surviving entity in
any permitted Transfer that directly or indirectly owns the applicable Partner
Sub Stock following such transaction, if other than a Parent. In addition, a
Parent and its Affiliates shall be released from all obligations under this
Section 1 and Section 3 at such time as neither such Parent nor any of its
Affiliates holds any Units in the Partnership pursuant to a Transfer of such
Units in accordance with the Partnership Agreement.

         1.4 SPECIAL PURPOSE SUBSIDIARIES. Each Parent covenants and agrees that
(i) the business of its Partner Subs shall be restricted solely to the holding
of the respective interests in the Partnership and the doing of things necessary
or appropriate in connection therewith, and (ii) it will cause its Partner Subs
not to own any assets, incur any liabilities or engage, participate or invest in
any business outside the scope of their businesses as described in clause (i)
hereof.


                                    SECTION 2
                 STANDSTILL AGREEMENT AND CERTAIN OTHER MATTERS
                 ----------------------------------------------

         2.1 STANDSTILL. Each Subject Parent agrees for the benefit of the other
Subject Parent that, until the fifth anniversary of the date of this Agreement,
neither it, nor any of its Affiliates shall, without prior written invitation or
request of the other Subject Parent: (i) in any manner acquire, agree to acquire
or make any proposal to acquire, directly or indirectly, any securities, assets
or property (other than an acquisition of assets or property in the ordinary
course of business) of the other Subject Parent, whether such agreement or
proposal is made with or to the other Subject Parent

                                       6


<PAGE>   8


or a third party; (ii) make any unsolicited proposal to enter into, directly or
indirectly, any merger or other business combination involving the other Subject
Parent; (iii) make, or in any way participate, directly or indirectly, in any
"solicitation" of "proxies" (as such terms are used in the proxy rules of the
Securities and Exchange Commission) to vote, or seek to advise or influence any
person with respect to the voting of, any voting securities of the other Subject
Parent; (iv) form, join or in any way participate in a "group" (within the
meaning of Section 13(d)(3) of the Securities Exchange Act of 1934) with respect
to any voting securities of the other Subject Parent; (v) otherwise act, alone
or in concert with others, to seek to control the management, board of directors
or policies of the other Subject Parent; (vi) disclose any intention, plan or
arrangement inconsistent with the foregoing; or (vii) advise, encourage, provide
assistance (including financial assistance) to or hold discussions with any
other Persons in connection with any of the foregoing. Each Subject Parent also
agrees during such period not to: (a) request that the other Subject Parent (or
its respective directors, officers, employees or agents), directly or
indirectly, amend or waive any provision of this Section 2.1 (including this
sentence); or (b) take any action that might reasonably be expected to require
that the other Subject Parent make a public announcement regarding the
possibility of a business combination or merger.

         2.2      EXCEPTIONS.  Notwithstanding the provisions of Section 2.1:

         (a) As to a Subject Parent, the provisions of Section 2.1 shall
automatically be terminated and of no further force and effect if any of the
following events occur with respect to the other Subject Parent: (i) a Change of
Control (as defined below) of the other Subject Parent shall have occurred, (ii)
the other Subject Parent shall have entered into a definitive agreement
providing for, or publicly announced its intention to effect, any transaction
involving a Change of Control of the other Subject Parent or (iii) a tender
offer or exchange offer shall have been commenced or publicly announced that, if
consummated, would have the effect with respect to the other Subject Parent
described in clause (C) of the definition of "Change of Control." A "Change of
Control" of a Subject Parent shall mean the occurrence of any of the following
events: (A) there shall be consummated any consolidation, conversion, merger or
share exchange of such Subject Parent (I) in which such Subject Parent is not
the continuing or surviving Person (other than a consolidation, merger or share
exchange with a wholly-owned subsidiary of such Subject Parent in which all
shares of common stock of such Subject Parent outstanding immediately prior to
the effectiveness thereof are changed into or exchanged for shares of common
stock of such subsidiary) or (II) pursuant to which the common stock of such
Subject Parent is converted into cash, securities or other property, other than,
in each case, a consolidation, conversion, merger or share exchange of such
Subject Parent in which the holders of the common stock immediately prior to the
consolidation, conversion, merger or share exchange hold, directly or
indirectly, at least a majority of the voting power and common equity of the
continuing or surviving Person immediately after such consolidation, conversion,
merger or share exchange; (B) such Subject Parent's properties and assets are
sold or otherwise disposed of substantially as an entirety on a consolidated
basis to any Person or group of Persons in any one transaction or a series of
related transactions, other than as contemplated by the Master Transaction
Agreement; or (C) any Person or any Persons acting together that would
constitute a "group" (as defined in Section 2.1) (other than such Subject
Parent, any subsidiary of 

                                       7
<PAGE>   9


such Subject Parent, any employee stock purchase plan, stock option plan or
other stock incentive plan or program, retirement plan or automatic dividend
reinvestment plan or any substantially similar plan of such Subject Parent or
any subsidiary of such Subject Parent or any Person holding securities of such
Subject Parent for or pursuant to the terms of any such employee benefit plan),
together with any Affiliates thereof, shall acquire beneficial ownership (as
defined in Rule 13d-3 under the Securities Exchange Act of 1934) of 50% or more
of the voting stock of such Subject Parent.

         (b) The terms of the first sentence of Section 2.1 shall not apply to
the purchase and sale of any securities of a Subject Parent by any pension or
other related employee benefit plans who are acting as passive investors in such
Subject Parent.


                                    SECTION 3
                                  MISCELLANEOUS
                                  -------------

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

         3.2 EXPENSES IN CONNECTION WITH EXERCISE. In the event of a dispute
between Parties regarding the exercise or enforcement of any of the rights of a
Party under this Agreement or the failure by a Party to perform or observe any
of the provisions of this Agreement, the Party or Parties that do not ultimately
prevail in such dispute shall be liable, and hereby agree, to reimburse, on
demand, each prevailing Party for any and all costs and expenses, including the
fees and expenses of legal counsel and of any other counsel, experts,
consultants or agents, that such prevailing Party may incur in connection
therewith.

         3.3 CONFIDENTIALITY AND USE OF INFORMATION.

         (a) Each Parent agrees that it and its Affiliates shall be bound by the
terms and conditions of Section 13.1 of the Partnership Agreement as if such
Person was a "Partner" as defined in such agreement.

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

         (c) The letter agreements regarding confidentiality dated January 21,
1998 and May 18, 1998 between Geon and OCC are hereby terminated.


                                       8
<PAGE>   10



         3.4 NON-SOLICITATION. Each Parent agrees that, for a period ending on
the first anniversary of the date of this Agreement (unless the applicability of
this provision is terminated earlier pursuant to Section 1.3), it will not, and
it will cause its Affiliates not to directly or knowingly induce or attempt to
induce any officers or employees of the Partnership to leave the employ of the
Partnership; PROVIDED, HOWEVER, that nothing in this Section 3.4 shall prohibit
any Parent or its Affiliates from hiring or engaging any of the foregoing who
respond to a general solicitation not directed specifically to officers or
employees of the Partnership.

         3.5 FURTHER ASSURANCES. From time to time, each Party agrees to execute
and deliver such additional documents and provide such additional information
and assistance as the other Parties may reasonably require to carry out the
terms of this Agreement.

         3.6 ASSIGNMENT; SUCCESSORS AND ASSIGNS.

         (a) Except as provided in this Agreement and except that a Parent may
assign its rights or obligations under this Agreement to a third party in
connection with a transfer of direct interests in the Partnership owned by its
Partner Subs if such transfer is permitted and consummated in accordance with
the Partnership Agreement, no Parent may assign or delegate any of its rights or
obligations under this Agreement without the prior written consent of the other
Parent, which consent shall be in the sole discretion of such other Parent. Any
purported assignment or delegation without such consent shall be void and
ineffective.

         (b) No Subject Parent may assign or delegate any of its rights or
obligations under this Agreement without the prior consent of the other Subject
Parent, which consent shall be in the sole discretion of such other Subject
Parent, except that a Subject Parent may assign its rights or obligations under
the agreement without such consent in connection with any Change of Control.

         3.7 BENEFITS OF AGREEMENT RESTRICTED TO THE PARTIES. This Agreement is
made solely for the benefit of the Parties, and no other Person shall have any
right, claim or cause of action under or by virtue of this Agreement.

         3.8 NOTICES. All notices, requests, demands and other communications
that are required or may be given under this Agreement shall be in writing and
shall be deemed to have been duly given if and when (i) transmitted by

transmitting machine or (ii) delivered by commercial courier or other hand

                                ----------------
                             (PVC POWDER BLENDS, LP)
                             -----------------------
                       AND BUSINESS OPPORTUNITY AGREEMENT
                       ----------------------------------


         This PARENT AGREEMENT (PVC POWDER BLENDS, LP) AND BUSINESS OPPORTUNITY
AGREEMENT (this "Agreement") dated as of the 30th day of April, 1999, is entered
into among Occidental Chemical Corporation, a New York corporation ("OCC"), The
Geon Company, a Delaware corporation ("Geon"), Occidental Petroleum Corporation,
a Delaware corporation ("OPC"), PVC Powder Blends, LP, a Delaware limited
partnership (the "Partnership"), and Oxy Vinyls, LP, a Delaware limited
partnership (the "PVC Partnership," and together with OCC, OPC, Geon, and the
Partnership, the "Parties", and each individually, a "Party").

         WHEREAS, each of OCC and Geon is a "Parent" for purposes of this
Agreement; and

         WHEREAS, each of OPC and Geon is a "Subject Parent" for purposes of
this Agreement; PROVIDED, HOWEVER, that neither OPC nor Geon shall be a "Subject
Parent" from and after the expiration of 12 months from the date on which it and
its Affiliates no longer hold any Units in the Partnership; and

         WHEREAS, Occidental PVC Compound LP, Inc., a Delaware corporation ("OCC
Partner Sub"), is a direct or indirect wholly-owned subsidiary of OCC; and OCC
is an indirect wholly-owned subsidiary of OPC; and

         WHEREAS, 1999 General Compounding Partner Inc., a Delaware corporation
("Geon GP"), and 1999 Limited Compounding Partner Inc., a Delaware corporation
("Geon LP" and, together with Geon GP, the "Geon Partner Subs"), are both direct
wholly-owned subsidiaries of Geon; and

         WHEREAS, OCC and Geon entered into a Master Transaction Agreement,
dated December 22, 1998 (the "Master Transaction Agreement"), providing for,
among other things, the formation of the Partnership pursuant to the Limited
Partnership Agreement of the Partnership dated as of the date of this Agreement
(the "Partnership Agreement") and the admission of the Geon Partner Subs and the
OCC Partner Sub as partners in the Partnership. The Geon Partner Subs and the
OCC Partner Sub, collectively or individually, as the context may require, are
referred to herein as the "Partner Subs"; and

         WHEREAS, this Agreement is essential to the consummation of the closing
pursuant to the Master Transaction Agreement; and

         WHEREAS, each Parent is willing to subject the Partner Sub Stock (as
defined in Section 1.1) to certain restrictions on transfer, as set forth in
this Agreement; and


                                       2

<PAGE>   4

         WHEREAS, each of OPC and Geon is willing to agree to certain covenants
in favor of the other in connection with the closing of the transactions
contemplated by the Master Transaction Agreement;

         NOW THEREFORE, in consideration of the foregoing and the mutual
promises and covenants of the Parties, the Parties hereby agree as follows:

                                    SECTION 1
                     OWNERSHIP AND BUSINESS OF PARTNER SUBS
                     --------------------------------------

         1.1      RESTRICTIONS ON TRANSFER AND PLEDGE OF PARTNER SUB STOCK.

         (a) Each Parent agrees that, except as otherwise provided below in this
Section 1, or with the written consent of the other Parent, which consent may be
granted or withheld in such Parent's sole discretion, it will not, in any
transaction or series of transactions, directly or indirectly, (i) sell, assign
or otherwise dispose of, whether by act, deed, merger or otherwise ("Transfer")
or (ii) mortgage, pledge, encumber or create or suffer to exist any lien or
encumbrance upon or security interest in ("Pledge"), all or any part of the
capital stock or other equity interests (including any securities convertible
into or exchangeable for or carrying any rights to purchase, subscribe for or
otherwise acquire any such capital stock or other equity interests) of its
Partner Subs (collectively, the "Partner Sub Stock"). (Each of the defined terms
"Transfer"and "Pledge" is used herein both as a noun and as a verb.) Any attempt
by a Parent to Transfer or Pledge all or a portion of its Partner Sub Stock in
violation of this Agreement shall be void AB INITIO and shall not be effective
to Transfer such Partner Sub Stock or any portion thereof. The Partnership
Agreement contains provisions relating to the Transfer and Pledge of the Partner
Subs' direct interests in the Partnership.

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

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

         (c) Without the need for the consent of any Person and without the
application of the requirements of Section 1.2, each Parent may Transfer all
(but not less than all) of its Partner Sub Stock, if such Transfer is: (i) in
connection with (A) a merger, consolidation, conversion, share 


                                       3

<PAGE>   5

exchange or Change of Control of such Parent or (B) a sale or other disposition
by such Parent of assets including the Partner Sub Stock where such Partner Sub
Stock constitutes less than 50% of the book value of the aggregate assets to be
sold or disposed of, as reflected on such Parent's most recent audited
consolidated (or combined) financial statements; (ii) to an 80%-Owned Affiliate
of such Parent; or (iii) to the shareholders of (A) such Parent, in the case of
Geon, or (B) OPC, in the case of OCC; PROVIDED, HOWEVER, that the requirements
of Section 1.2(d)(i)-(vi) must be satisfied in connection therewith. For
purposes of the preceding sentence, the term "Change of Control" shall (A) for
Geon be defined in the same way as that term is defined for Geon in Section 2.2
in its capacity as a Subject Parent and (B) for OCC mean an event or
circumstance that results in OCC's no longer being an Affiliate of OPC.

         (d) Except as provided in Section 1.1(c), nothing in this Agreement
shall prevent or restrict the Transfer or Pledge of the capital stock, equity
ownership interests or other securities of a Parent or any Person that owns a
direct or indirect interest in a Parent, and no such Transfer or Pledge of
securities issued by a Parent shall be deemed to constitute a Transfer or Pledge
of Partner Sub Stock hereunder.

         (e) Each Parent (so long as such Parent is performing its obligations
hereunder) may Pledge all (but not less than all) of its Partner Sub Stock in
connection with a loan to such Parent, PROVIDED that (i) the loan to such Parent
has been approved by the Partnership and (ii) the Pledge shall be evidenced by
an instrument, reasonably satisfactory to the Partnership, wherein, in the case
of the Partner Sub Stock of Geon GP and Geon LP, the lender receiving such
Pledge shall agree that in the event such lender obtains a right of foreclosure
on Geon's Partner Sub Stock, such lender will foreclose on the Partner Sub Stock
of Geon's Partner Subs proportionately so that such lender will in all events
hold portions of Partner Sub Stock of Geon GP and Geon LP proportionate to
Geon's holdings thereof.

         1.2      RIGHT OF FIRST REFUSAL AND RIGHT OF FIRST OPTION.

         (a) Without the consent of the other Parent, no Parent may Transfer
less than all of its Partner Sub Stock, and unless such Transfer is otherwise
permitted by Section 1.1, no Parent may Transfer its Partner Sub Stock, directly
or indirectly, for consideration other than cash. Unless such Transfer is
otherwise permitted by Section 1.1, any Parent (the "Selling Parent") that
receives a bona fide offer to purchase all of its Partner Sub Stock that it
desires to accept (an "Offer") or that otherwise desires to Transfer all of its
Partner Sub Stock to any Person shall give written notice (the "Initial Notice")
to the Partnership and the other Parent (the "Offeree Parent") stating that the
Selling Parent has received an Offer or otherwise desires to Transfer its
Partner Sub Stock and shall set forth the cash purchase price and all other
terms of the Offer or the cash purchase price (established as provided below)
and all other terms on which it otherwise is willing to sell its Partner Sub
Stock (in each case, the "Offer Terms"). In establishing the Offer Terms for a
proposed sale that does not involve an Offer, the Selling Parent shall obtain an
appraisal from an independent appraiser with a reasonable level of industry
experience of the cash price that a willing buyer under no compulsion to buy
would pay and a willing seller under no compulsion to sell would accept for the
Partner Sub 

                                       4

Stock of the Selling Parent (the "Fair Market Value"). Delivery of an Initial
Notice shall constitute the irrevocable offer of the Selling Parent to sell its
Partner Sub Stock to the Offeree Parent hereunder.

         (b) The Offeree Parent shall have the option, exercisable by delivering
written notice (the "Acceptance Notice") of such exercise to the Selling Parent
within 60 days of the date of the Initial Notice, to elect to purchase all, but
not less than all, of the Partner Sub Stock of the Selling Parent on the Offer
Terms described in the Initial Notice. The Acceptance Notice shall set a date
for closing the purchase, such date to be not less than 30 nor more than 90 days
after delivery of the Acceptance Notice; PROVIDED, HOWEVER, that such time
period shall be subject to extension as reasonably necessary (up to a maximum of
an additional 120 days after such 90 day period) in order to comply with any
applicable filing and waiting period requirements under the Hart-Scott-Rodino
Antitrust Improvements Act (or any successor statute) or other Legal
Requirement. The closing shall be held at the Partnership's offices. The
purchase price for the Selling Parent's Partner Sub Stock shall be paid in
immediately available funds delivered at the closing, and all actions at the
closing shall conform in all material respects to the Offer Terms.

         (c) If the Offeree Parent does not elect to purchase all of the Selling
Parent's Partner Sub Stock within 60 days after the receipt of the Initial
Notice, the Selling Parent shall have a further 180 days during which it may,
subject to Section 1.2(d), consummate the sale of its Partner Sub Stock (i)
substantially in accordance with the terms of the Offer or (ii) if no Offer is
involved, to a third party purchaser on terms that are not substantially more
favorable to such purchaser than the Offer Terms and at a price equal to not
less than 90% of the Fair Market Value of the Partner Sub Stock. If the sale is
not completed within such further 180-day period, the Initial Notice shall be
deemed to have expired and a new notice and offer shall be required before the
Selling Parent may make any Transfer of its Partner Sub Stock. If the Selling
Parent receives a written offer during such further 180-day period from a third
party purchaser that is for less than 90% of the Fair Market Value, and the
Selling Parent is willing to accept the offer, then (1) the offer shall be
treated as an Offer, and (2) the Selling Parent must comply with the provisions
of this Section 1.2 before the Selling Parent may make any Transfer of its
Partner Sub Stock to the third party purchaser that made the Offer.

         (d) Notwithstanding the foregoing provisions of this Section 1.2,
except as provided in Section 1.1(c), a Parent may Transfer its Partner Sub
Stock only if all of the following occur:

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

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

                                       5
<PAGE>   7

                  (iii) The Transfer does not cause a default under any material
         contract (A) that has been approved unanimously by the Partnership
         Governance Committee and (B) to which the Partnership is a party or by
         which the Partnership or any of its properties is bound.

                  (iv) The Successor Parent executes an appropriate agreement to
         be bound by this Agreement.

                  (v) The transferor and transferee bear all reasonable costs
         incurred by the Partnership in connection with the Transfer.

                  (vi) The provisions of Section 1.2(e) are satisfied.

                  (vii) The Successor Parent must have sufficient resources to
         assume the obligations of the Parent, including any capital that may
         reasonably be expected to be requested from its Partner Subs by the
         Partnership under the then effective Strategic Plan, or the Successor
         Parent's obligations must be supported by a guarantee, letter of credit
         or other credit support reasonably satisfactory to the other Parent,
         and such Successor Parent must otherwise be reasonably acceptable to
         the other Parent.

         (e) Geon may Transfer the Partner Sub Stock of either of its Partner
Subs to any Person only if it simultaneously Transfers the Partner Sub Stock of
its other Partner Sub to such Person or a wholly-owned Affiliate of such Person.

         1.3 EFFECT OF TRANSFER. Upon completion of any Transfer that is
permitted hereunder, the Successor Parent shall succeed to and be substituted
for the applicable Parent, with the same effect as if it had been named herein,
and unless such Parent shall then be an Affiliate of such Successor Parent, such
Parent and its Affiliates shall thereupon be released from all obligations under
this Section 1 and Section 3. For purposes of this Section 1, the term
"Successor Parent" shall mean the acquiring, succeeding or surviving entity in
any permitted Transfer that directly or indirectly owns the applicable Partner
Sub Stock following such transaction, if other than a Parent. In addition, a
Parent and its Affiliates shall be released from all obligations under this
Section 1 and (except as provided in Section 3.10) Section 3 at such time as
neither such Parent nor any of its Affiliates holds any Units in the Partnership
pursuant to a Transfer of such Units in accordance with the Partnership
Agreement.

         1.4 SPECIAL PURPOSE SUBSIDIARIES. Each Parent covenants and agrees that
(i) the business of its Partner Subs shall be restricted solely to the holding
of the respective interests in the Partnership and the doing of things necessary
or appropriate in connection therewith, and (ii) it will cause its Partner Subs
not to own any assets, incur any liabilities or engage, participate or invest in
any business outside the scope of their businesses as described in clause (i)
hereof.

                                    SECTION 2
                 STANDSTILL AGREEMENT AND CERTAIN OTHER MATTERS
                 ----------------------------------------------

         2.1 STANDSTILL. Each Subject Parent agrees for the benefit of the other
Subject Parent that, until the fifth anniversary of the date of this Agreement,
neither it, nor any of its Affiliates shall, without prior written invitation or
request of the other Subject Parent: (i) in any manner acquire, agree to acquire
or make any proposal to acquire, directly or indirectly, any securities, assets
or property (other than an acquisition of assets or property in the ordinary
course of business) of the other Subject Parent, whether such agreement or
proposal is made with or to the other Subject Parent or a third party; (ii) make
any unsolicited proposal to enter into, directly or indirectly, any merger or
other business combination involving the other Subject Parent; (iii) make, or in
any way participate, directly or indirectly, in any "solicitation" of "proxies"
(as such terms are used in the proxy rules of the Securities and Exchange
Commission) to vote, or seek to advise or influence any person with respect to
the voting of, any voting securities of the other Subject Parent; (iv) form,
join or in any way participate in a "group" (within the meaning of Section
13(d)(3) of the Securities Exchange Act of 1934) with respect to any voting
securities of the other Subject Parent; (v) otherwise act, alone or in concert
with others, to seek to control the management, board of directors or policies
of the other Subject Parent; (vi) disclose any intention, plan or arrangement
inconsistent with the foregoing; or (vii) advise, encourage, provide assistance
(including financial assistance) to or hold discussions with any other Persons
in connection with any of the foregoing. Each Subject Parent also agrees during
such period not to: (a) request that the other Subject Parent (or its respective
directors, officers, employees or agents), directly or indirectly, amend or
waive any provision of this Section 2.1 (including this sentence); or (b) take
any action that might reasonably be expected to require that the other Subject
Parent make a public announcement regarding the possibility of a business
combination or merger.

         2.2      EXCEPTIONS.  Notwithstanding the provisions of Section 2.1:

         (a) As to a Subject Parent, the provisions of Section 2.1 shall
automatically be terminated and of no further force and effect if any of the
following events occur with respect to the other Subject Parent: (i) a Change of
Control (as defined below) of the other Subject Parent shall have occurred, (ii)
the other Subject Parent shall have entered into a definitive agreement
providing for, or publicly announced its intention to effect, any transaction
involving a Change of Control of the other Subject Parent or (iii) a tender
offer or exchange offer shall have been commenced or publicly announced that, if
consummated, would have the effect with respect to the other Subject Parent
described in clause (C) of the definition of "Change of Control." A "Change of
Control" of a Subject Parent shall mean the occurrence of any of the following
events: (A) there shall be consummated any consolidation, conversion, merger or
share exchange of such Subject Parent (I) in which such Subject Parent is not
the continuing or surviving Person (other than a consolidation, merger or share
exchange with a wholly-owned subsidiary of such Subject Parent in which all
shares of common stock of such Subject Parent outstanding immediately prior to
the effectiveness thereof are changed into or exchanged for shares of common
stock of such subsidiary) or (II) pursuant to which the common stock of such
Subject Parent is converted into cash, securities or other property,

                 GEON COMPLETES RESIN JOINT VENTURE WITH OXYCHEM

Cleveland, Ohio - May 3, 1999 - The Geon Company (NYSE:GON) announced today that
Oxy Vinyls, LP (OxyVinyls), its joint venture with the OxyChem division of
Occidental Petroleum Corporation, began operations on May 1, as expected.
OxyVinyls combined the two companies polyvinyl chloride (PVC)/vinyl chloride
monomer resin businesses and other related operations.

Geon will own 24 percent and OxyChem 76 percent of OxyVinyls, which will be
North America's largest and the world's third-largest PVC producer.

Previously, the joint venture underwent federal government review and received
the approval of the boards of directors of both Geon and Occidental Petroleum.
On April 19, Geon stockholders approved the transaction.

"This is an important beginning for both the joint venture and the 'new' Geon,"
said William F. Patient, chairman and chief executive officer. "Adding OxyChem's
compounding and film businesses to Geon is a significant next step as we create
a multi-billion-dollar global performance polymers and services business."

As part of its agreements with OxyChem, Geon acquired OxyChem's compound and
vinyl film businesses in Burlington, New Jersey, and will create another,
smaller joint venture for dry blend compounding. Geon also will receive $110
million in cash and/or cash equivalents, and will transfer $185 million in debt
to OxyVinyls.

The Geon Company is a leading North American-based polymer services and
technology company with operations in PVC compounds, specialty PVC resins and
other value-added products and services. Headquartered in Avon Lake, Ohio, The
Geon Company and its subsidiaries employ more than 2,400 people and have 24
manufacturing plants in the United States, Canada, England and Australia, and
joint ventures in the United States, Canada, England, Australia and Singapore.
