CHAIRMAN AND CHIEF EXECUTIVE OFFICER
 
   
                                 March 29, 1999
    
 
Dear Stockholder:
 
   
     We cordially invite you to attend a Special Meeting of the stockholders of
The Geon Company ("Geon") to be held on April 19, 1999, at 9:00 a.m., Eastern
Standard Time, at The Fountaine Bleau Party Center, 635 Miller Road, Avon Lake,
Ohio.
    
 
     At the Special Meeting, we will ask you to consider and vote upon a
proposal to approve the contribution of certain assets and liabilities of Geon
to two joint ventures to be formed with Occidental Chemical Corporation, a New
York corporation ("OxyChem") and an indirect, wholly-owned subsidiary of
Occidental Petroleum Corporation. One joint venture will be named "Oxy Vinyls,
LP" (the "PVC Partnership") and will operate a business that produces and
markets polyvinyl chloride ("PVC") suspension and mass resins and vinyl chloride
monomer ("VCM") and produces chlor-alkali products. The other joint venture will
be named "PVC Powder Blends LP" (the "Compounding Partnership") and will operate
a powder/dry blend compound business. Both joint ventures will be organized as
Delaware limited partnerships. The PVC Partnership will be headquartered
initially in Dallas, Texas, and the Compounding Partnership will be
headquartered in Avon Lake, Ohio.
 
     If you approve the proposal to form the joint ventures, Geon will
contribute to the PVC Partnership five PVC suspension and mass resin plants and
one VCM plant, together with certain related assets. In exchange, Geon will
receive a 24% interest in the PVC Partnership, and the PVC Partnership will
assume certain liabilities and obligations of Geon aggregating $185 million,
including the obligations of Geon under a lease pursuant to which Geon leases a
portion of a VCM plant located in LaPorte, Texas, as well as certain industrial
revenue bond debt of Geon. Geon will also execute long-term PVC and VCM supply
agreements with the PVC Partnership. OxyChem will contribute to the PVC
Partnership one PVC plant, one VCM plant, a 50% interest in OxyMar, a Texas
general partnership which operates a VCM plant ("OxyMar"), and a chlor-alkali
chemical complex that produces raw materials necessary for the production of
PVC, together with certain related assets. In exchange, OxyChem will receive a
76% interest in the PVC Partnership, and the PVC Partnership will assume certain
liabilities and obligations of OxyChem, including certain OxyMar debt. In
connection with the transaction, Geon will realize $110 million through the
retention of certain working capital and the distribution of cash from the PVC
Partnership.
 
     Geon will contribute to the Compounding Partnership substantially all of
its powder/dry blend compounding assets and its powder compound manufacturing
facility located at Plaquemine, Louisiana. In exchange, Geon will receive a 90%
interest in the Compounding Partnership, and the Compounding Partnership will
assume certain liabilities and obligations of Geon. OxyChem will contribute to
the Compounding Partnership substantially all of its compounding assets and
powder compound business located at Pasadena, Texas, as well as a separate
tolling arrangement. In exchange, OxyChem will receive a 10% interest in the
Compounding Partnership, and the Compounding Partnership will assume certain
liabilities and obligations of OxyChem. In addition to the foregoing, OxyChem
will transfer to Geon a PVC flexible film and pellet compounding plant located
in Burlington, New Jersey, and its specialty pellet compound business.

     Geon believes that the joint venture transactions with OxyChem represent a
logical extension of Geon's strategic plans to enhance stockholder value. We
believe it will provide opportunities for Geon to redirect its focus to the
performance polymers and services business while the PVC Partnership will create
a low-cost producer of PVC resins capable of competing effectively in the highly
competitive PVC resins industry.
 
     The Board of Directors of Geon has unanimously approved the joint venture
transactions and unanimously recommends that stockholders vote "FOR" the joint
venture proposal described in the accompanying Proxy Statement. The joint
venture transactions are subject to approval by stockholders holding at least a
majority of the outstanding shares of Geon Common Stock entitled to vote.
 
     In addition, at the Special Meeting, we will ask you to adopt The Geon
Company 1999 Incentive Stock Plan which the Board of Directors of Geon has
approved and recommended a vote "FOR."
 
     DETAILS ABOUT THE JOINT VENTURE TRANSACTIONS AND THE GEON COMPANY 1999

AND PROXY STATEMENT. EVERY STOCKHOLDER SHOULD CONSIDER THESE DOCUMENTS
CAREFULLY.

                          TO BE HELD ON APRIL 19, 1999
    
 
TO THE STOCKHOLDERS:
 
   
     You are hereby notified that a Special Meeting of the stockholders of The
Geon Company, a Delaware corporation ("Geon"), will be held on April 19, 1999,
at 9:00 a.m., Eastern Standard Time, at The Fountaine Bleau Party Center, 635
Miller Road, Avon Lake, Ohio, for the following purposes:
    
 
          1. To consider and vote upon a proposal (the "Joint Venture Proposal")
     described in the accompanying Proxy Statement providing for:
 
             (i) the contribution to the PVC Partnership of Geon's five
        polyvinyl chloride suspension and mass resin plants (Deer Park, Texas;
        Louisville, Kentucky; Niagara Falls, Ontario, Canada; Pedricktown, New
        Jersey; and Fort Saskatchewan, Alberta, Canada) and one vinyl chloride
        monomer plant (LaPorte, Texas), together with certain related assets and
        liabilities, and all of the outstanding capital stock of LaPorte
        Chemicals Corporation, and
 
             (ii) the contribution to the Compounding Partnership of
        substantially all of Geon's powder/dry blend compounding assets and its
        powder compound business located at Plaquemine, Louisiana, together with
        certain related liabilities;
 
          2. To adopt The Geon Company 1999 Incentive Stock Plan (the "Stock
     Plan Proposal"); and
 
          3. To consider such other business as may properly come before the
     Special Meeting.
 
   
     The record date for stockholders entitled to notice of and to vote at the
Special Meeting is the close of business on March 23, 1999. This Notice, the
Proxy Statement and the accompanying form of proxy are first being mailed to
stockholders of Geon on or about March 29, 1999.
    
 
     The Board of Directors of Geon (the "Geon Board") has retained discretion,
even if stockholder approval of the Joint Venture Proposal is obtained and the
other conditions to the joint venture transactions are satisfied, to abandon,
defer or modify the joint venture transactions or any other element contained in
the Joint Venture Proposal. If the Geon Board takes any such action, it will be
on the basis that the Geon Board believes that it will be in the best interests
of Geon and its stockholders. If the Geon Board modifies the terms of the Joint
Venture Proposal and such modifications in the aggregate are material, Geon will
resolicit stockholder approval as more fully discussed under the heading
"Purpose of the Special Meeting" of this Proxy Statement.
 
     THE GEON BOARD UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" THE
JOINT VENTURE PROPOSAL AND THE STOCK PLAN PROPOSAL.
 
     You are invited to attend the Special Meeting, but whether or not you
expect to attend in person, please mark, sign, date and return the enclosed
proxy in the accompanying postage-paid envelope so that your shares will be
represented at the meeting and any adjournment thereof. PLEASE DO NOT SEND IN
YOUR STOCK CERTIFICATES WITH YOUR PROXY CARD.

                           CAUTIONARY NOTE REGARDING
                           FORWARD-LOOKING STATEMENTS
 
     We caution you that this Proxy Statement contains forward-looking
statements within the meaning of Section 21E of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), including, without limitation, statements
concerning the future development of Geon's business following the completion of
the joint venture transactions with, and the transfer of certain businesses to
Geon by, Occidental Chemical Corporation ("OxyChem"), the future operations of
the joint ventures, and the synergies expected to result therefrom.
Forward-looking statements often begin with or include the phrases "we believe",
"Geon expects", "we intend" or words of similar meaning. Although we believe our
expectations reflected in such forward-looking statements are based on
reasonable assumptions, such expectations may not prove to be correct. Important
factors that could cause actual results to differ materially from the
expectations reflected in our forward-looking statements include, among others,
(1) unanticipated changes in the world, regional, or United States polyvinyl
chloride consumption growth rate affecting Geon's markets; (2) unanticipated
changes in global industry capacity or in the rate at which anticipated changes
in industry capacity come online in the polyvinyl chloride, vinyl chloride
monomer, and chlor-alkali industries; (3) fluctuations in raw material prices
and supply, and in particular, fluctuations outside the normal range of industry
cycles; (4) unanticipated delays in achieving or inability to achieve cost
reduction and employee productivity goals; (5) unanticipated difficulties or
delays in coordinating and integrating historically separate organizations and
facilities in connection with the proposed transactions; (6) unanticipated
production outages; (7) the impact on the North American vinyl markets and
supply/demand balance resulting from global economic conditions; (8) the ability
to obtain financing at anticipated rates; (9) unanticipated expenditures
required in conjunction with year 2000 compliance; (10) unanticipated delays in
realizing, or inability to realize, expected cost savings from the proposed
transactions and the consolidation of Geon's compounding operations; (11)
unanticipated costs or difficulties related to completion of the proposed
transactions, or the operation of the joint ventures, or the consolidation of
Geon's compounding operations; and (12) unanticipated delays in completing, or
inability to complete, the proposed transactions as a result, among other
things, of investigation of, and possible opposition to, the proposed
transactions from the Federal Trade Commission.
 
           QUESTIONS AND ANSWERS ABOUT THE JOINT VENTURE TRANSACTIONS
 
Q: WHAT IS OXY VINYLS, LP, AND WHAT IS PVC POWDER BLENDS LP?
 
 A: Oxy Vinyls, LP is the name of the joint venture limited partnership we and
    OxyChem are forming to operate polyvinyl chloride ("PVC") suspension and
    mass resin, vinyl chloride monomer ("VCM") and chlor-alkali products
    businesses using certain assets contributed to it by Geon and OxyChem. PVC
    Powder Blends LP is the name of the joint venture we and OxyChem are forming
    to operate a powder/dry blend compounding business using certain assets
    contributed to it by Geon and OxyChem. Oxy Vinyls, LP is referred to in this
    Proxy Statement as the "PVC Partnership," PVC Powder Blends LP is referred
    to as the "Compounding Partnership," and the PVC Partnership and the
    Compounding Partnership are referred to collectively as the "Partnerships."
    The term "Joint Venture Transactions" refers to the formation of, and the
    contribution of certain assets, stock, partnership interest, and liabilities
    to, the Partnerships by Geon and OxyChem.
 
Q: WHY ARE GEON AND OXYCHEM PROPOSING TO CREATE THE PARTNERSHIPS? HOW WILL I
   BENEFIT?
 
 A: We are proposing to combine certain assets in the Partnerships because we
    believe the Partnerships represent a logical extension of Geon's strategic
    plans to enhance stockholder value. In particular, we believe that the
    Partnerships will provide opportunities for Geon to redirect its focus to
    the performance polymers and services business while creating in the PVC
    Partnership the low-cost producer of PVC resins capable of competing
    effectively in the highly competitive PVC resins industry. We and OxyChem
    expect that the PVC Partnership will be positioned to become the low-cost
    North American PVC suspension and mass resin manufacturer and that the
    Compounding
 
                                        i
<PAGE>   6
 
   
    Partnership will operate as a more cost effective powder compounding
    business. Accordingly, we believe that forming the Partnerships will result
    in improved product and service offerings to our customers. Geon believes
    that over time the Partnerships will provide a significantly better return
    on the assets being contributed to the Partnerships than Geon could achieve
    otherwise. We expect that this added value will benefit all of Geon's
    stockholders. To review the background and reasons for the Joint Venture
    Transactions in greater detail, see pages 25 through 31.
    
 
Q: WHO ARE THE GENERAL PARTNERS AND LIMITED PARTNERS OF THE PARTNERSHIPS?
 
 A: An indirect, wholly-owned subsidiary of OxyChem will be the general partner
    of the PVC Partnership, and a wholly-owned subsidiary of Geon ("Geon
    Compounding General Partner") will be the general partner of the Compounding
    Partnership. The general partner of each Partnership will be responsible for
    operating its Partnership and will have unlimited liability for the debts
    and other liabilities of its Partnership.
 
    A wholly-owned subsidiary of Geon and a wholly-owned subsidiary of OxyChem
    will be the limited partners of the PVC Partnership, and a wholly-owned
    subsidiary of Geon and a wholly-owned subsidiary of OxyChem will be the
    limited partners of the Compounding Partnership.
 
Q: HOW WILL THE PVC PARTNERSHIP BE MANAGED?
 
 A: The executive officers of the PVC Partnership will manage the day-to-day
    operations of the PVC Partnership under the supervision of a Partnership
    Governance Committee (the "PVC Partnership Governance Committee") that will
    act much like a board of directors of a corporation.
 
   
    Generally, through wholly-owned subsidiaries, OxyChem will control the
    operations and decision-making of the PVC Partnership. However, Geon will
    have certain protective rights which would preclude OxyChem from taking
    unilateral action on certain matters. Such matters include changes in the
    scope of the PVC Partnership's business, approval of the annually updated
    five-year strategic plan that will define the business goals and strategy of
    the PVC Partnership, and sales or purchases of assets outside the ordinary
    course of business or capital expenditures of more than $25 million that are
    not contemplated by the then-current strategic plan. A list of all matters
    requiring Geon's consent is set forth in this Proxy Statement on pages 60
    and 62.
    
 
Q: HOW WILL THE COMPOUNDING PARTNERSHIP BE MANAGED?
 
 A: Geon Compounding General Partner will manage the day-to-day operations of
    the Compounding Partnership under the supervision of a Partnership
    Governance Committee (the "Compounding Partnership Governance Committee")
    that will act much like a board of directors of a corporation.
 
   
    Generally, through wholly-owned subsidiaries, Geon will control the
    operations and decision-making of the Compounding Partnership. However,
    OxyChem will have certain protective rights which would preclude Geon from
    taking unilateral action on certain matters. Such matters include changes in
    the scope of the Compounding Partnership's business, approval of the
    annually updated three-year strategic plan that will define the business
    goals and strategy of the Compounding Partnership, and sales or purchases of
    assets outside the ordinary course of business or capital expenditures of
    more than $2 million that are not contemplated by the then-current strategic
    plan. A list of all matters requiring OxyChem's consent is set forth in this
    Proxy Statement on pages 74 and 76.
    
 
Q: WHAT PARTS OF GEON WILL BE CONTRIBUTED TO THE PVC PARTNERSHIP AND THE
   COMPOUNDING PARTNERSHIP?
 
 A: Geon will contribute five PVC suspension and mass resin plants to the PVC
    Partnership, together with certain related assets. Such plants are located
    in Deer Park, Texas; Louisville, Kentucky; Niagara Falls, Ontario, Canada;
    Pedricktown, New Jersey; and Fort Saskatchewan, Alberta, Canada. In
    addition, Geon will contribute to the PVC Partnership its LaPorte, Texas,
    VCM plant and all of the outstanding capital stock of LaPorte Chemicals
    Corporation, a Delaware corporation which owns the foregoing Canadian
    assets. These plants had a nominal base capacity in 1998 of 2.4 billion
    pounds of PVC and 2.4 billion pounds of VCM. The PVC Partnership will also
    assume certain
 
                                       ii
<PAGE>   7
 
    related liabilities and obligations of Geon aggregating $185 million,
    including the obligations of Geon under a lease pursuant to which Geon
    leases a portion of a VCM plant located in LaPorte, Texas, as well as
    certain industrial revenue bond debt of Geon.
 
    Geon will contribute substantially all of its powder/dry blend compounding
    assets and its powder compound manufacturing site located at Plaquemine,
    Louisiana, to the Compounding Partnership. Assuming the consolidation of
    Geon's compounding assets following the Joint Venture Transactions, the
    capacity of these contributed assets constitutes less than 10% of Geon's
    total compounding capacity. The Compounding Partnership will also assume
    certain related liabilities and obligations of Geon.
 
   
    For a more detailed description of the assets being contributed to the
    Partnerships by Geon, see pages 45 through 47.
    
 
Q: WHAT PARTS OF OXYCHEM WILL BE CONTRIBUTED TO THE PVC PARTNERSHIP AND THE
   COMPOUNDING PARTNERSHIP?
 
 A: OxyChem will contribute to the PVC Partnership one PVC plant, located in
    Pasadena, Texas, one VCM plant, located in Deer Park, Texas, and its 50%
    interest in OxyMar, a Texas general partnership that operates a VCM plant in
    Ingleside, Texas ("OxyMar"). These plants, including 50% of the capacity of
    OxyMar's VCM plant in Ingleside, Texas, had a nominal base capacity in 1998
    of 1.8 billion pounds of PVC and 2.3 billion pounds of VCM. OxyChem will
    also contribute to the PVC Partnership its Houston Chlor-Alkali Complex,
    comprised of its Deer Park and Battleground, Texas, plants, which produces
    caustic soda and chlorine and operates co-generation power plants, together
    with certain related assets. The Houston Chlor-Alkali Complex had a nominal
    base capacity in 1998 of 1.8 billion pounds of chlorine and 2.0 billion
    pounds of caustic soda. In addition, the PVC Partnership will assume certain
    related liabilities and obligations of OxyChem, including certain OxyMar
    debt. OxyChem will contribute to the Compounding Partnership substantially
    all of its compounding assets and powder compound business located in
    Pasadena, Texas. The Compounding Partnership will also assume certain
    related liabilities and obligations of OxyChem.
 
   
    For a more detailed description of the assets being contributed to the
    Partnerships by OxyChem, see pages 46 and 47.
    
 
Q: WHAT BUSINESSES WILL GEON KEEP AND NOT CONTRIBUTE TO THE PARTNERSHIPS?
 
 A: The businesses retained by Geon following the Joint Venture Transactions
    will include Geon's vinyl compounding (other than powder/dry blend
    compounding), specialty resin, and plastisol formulation businesses. With
    respect to each of these retained businesses, Geon believes it is the North
    American sales leader with strong technology. These retained businesses,
    together with Geon's interest in each of the Partnerships, will form the
    platform from which Geon will seek to become an international performance
    polymer and service company with the potential for greater earnings growth
    and reduced commodity earnings volatility. Geon will also retain its 50%
    equity interest in the Sunbelt Chlor Alkali Partnership, a joint venture
    with Olin Corporation, and its 37.4% equity interest in Australian Vinyls
    Corporation, a joint venture with Orica, Ltd. of Melbourne, Victoria,
    Australia. Including the consolidated sales of the Compounding Partnership,
    these businesses are expected to have sales of approximately $1.2 billion in
    1999.
 
    Through a wholly-owned subsidiary, Geon will also own a 24% equity interest
    in the PVC Partnership. Initially, Geon expects that the PVC and VCM product
    consumption of Geon's retained businesses will approximate 24% of the
    expected product output of the PVC Partnership. Geon expects its ownership
    interest in the PVC Partnership to partially counter the effect of price
    fluctuations of PVC, a commodity. As margins of chlor-alkali, PVC, and VCM
    increase, Geon believes that the additional costs to its retained
    compounding businesses will be offset by its interest in the profits of the
    PVC Partnership. As a result, Geon expects that it will experience less
    commodity-type fluctuations in its earnings. Through wholly-owned
    subsidiaries, Geon will also own a 90% interest in the Compounding
    Partnership and will manage its operations.
 
                                       iii
<PAGE>   8
 
Q: WHAT DOES GEON GET FOR CONTRIBUTING BUSINESSES TO THE PARTNERSHIPS?
 
 A: Geon will receive a 24% interest in the PVC Partnership and a 90% interest
    in the Compounding Partnership in exchange for its contributions to the
    Partnerships. These interests will be owned by wholly-owned subsidiaries of
    Geon. In connection with the Joint Venture Transactions, Geon will realize
    $110 million through the retention of certain working capital and the
    distribution of cash from the PVC Partnership. Geon will also execute
    long-term PVC and VCM supply agreements with the PVC Partnership. In
    addition, OxyChem will transfer to Geon a PVC flexible film and pellet
    compounding plant and its specialty pellet compound business.
 
Q: WILL GEON BE REQUIRED TO FUND THE PARTNERSHIPS IN THE FUTURE?
 
 A: Generally, the Partnerships are expected to be self-funded through
    internally generated profits and cash flows. Until the PVC Partnership
    establishes its own credit rating, its credit requirements are expected to
    be funded through intercompany loans provided to the PVC Partnership by
    Occidental Petroleum Corporation. The Partnership Agreements, however,
    provide for cash contributions by Geon and OxyChem under certain
    circumstances.
 
Q: WHO ARE THE EXECUTIVES THAT WILL OPERATE THE PARTNERSHIPS?
 
 A: The PVC Partnership Governance Committee is expected to elect John L. Hurst,
    III, as President and Chief Executive Officer of the PVC Partnership. The
    Compounding Partnership will have no employees. The Compounding Partnership
    will be operated by Geon and its employees pursuant to a partnership
    agreement.
 
Q: WHAT ARE THE TAX CONSEQUENCES TO ME OF THE JOINT VENTURE TRANSACTIONS?
 
 A: The Joint Venture Transactions will have no federal income tax consequences
    for you as a stockholder of Geon.
 
Q: WHAT VOTE IS REQUIRED IN ORDER TO APPROVE THE JOINT VENTURE TRANSACTIONS?
 
 A: At Geon's special meeting, we must receive votes "FOR" the Joint Venture
    Proposal from holders of a majority of the shares of Geon Common Stock that
    are issued and outstanding as of the record date in order to approve the
    Joint Venture Transactions.
 
Q: IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
   SHARES FOR ME?
 
 A: Your broker will vote your shares only if you provide instructions to your
    broker on how to vote. You should provide such instructions in the manner
    prescribed by your broker. Without instructions, your shares will not be
    voted.
 
Q: SHOULD I SEND IN MY STOCK CERTIFICATES?
 
 A: No. The Joint Venture Transactions will not affect your stock certificates.
    You will continue to hold shares in Geon.
 
Q: WHEN WILL THE SPECIAL MEETING OCCUR?
 
   
 A: The special meeting of the stockholders of Geon will take place at 9:00 a.m.
    local time (E.S.T.) on April 19, 1999, at The Fountaine Bleau Party Center,
    635 Miller Road, Avon Lake, Ohio. You may attend the special meeting and
    vote your shares in person, rather than signing and mailing your proxy card.
    In addition, you may take back your proxy up until and including the day of
    the special meeting by following the directions on page 26 and change your
    vote by either signing a new proxy or attending the special meeting and
    voting in person.
    
 
Q: WHAT DO I NEED TO DO NOW?
 
 A: Complete, sign and mail your proxy card in the enclosed return envelope as
    soon as possible so that your shares will be represented at the special
    meeting. YOU SHOULD NOT SEND IN YOUR STOCK CERTIFICATES.

          1. The contribution of certain of Geon's assets and liabilities as
     follows (the "Joint Venture Proposal"):
 
             (i) the contribution to the PVC Partnership of five PVC suspension
        and mass resin plants (Deer Park, Texas; Louisville, Kentucky; Niagara
        Falls, Ontario, Canada; Pedricktown, New Jersey; and Fort Saskatchewan,
        Alberta, Canada), and the LaPorte, Texas, VCM plant, together with
        certain related assets and liabilities, and all of the outstanding
        capital stock of LaPorte Chemicals Corporation ("LaPorte Chemicals"),
        and
 
             (ii) the contribution to the Compounding Partnership of
        substantially all of Geon's powder/dry blend compounding assets and its

     Voting Rights and Vote Required. Only Geon stockholders as of the close of

     Appraisal Rights. Stockholders of Geon will not be entitled to appraisal
rights under Delaware law in connection with the Joint Venture Proposal.
 
   
THE JOINT VENTURE TRANSACTIONS (Pages 25-38)
    
 
     The Transactions. Geon and OxyChem have agreed to form two joint ventures,
one of which will operate a business that produces and markets PVC suspension
and mass resins, VCM and chlor-alkali products and will be named Oxy Vinyls, LP.
The other joint venture will operate a powder/dry blend compounding business and
will be named PVC Powder Blends LP. Both joint ventures will be organized as
Delaware limited partnerships.
 
     Under four Asset Contribution Agreements, one for each of Geon and OxyChem
for each Partnership (collectively, the "Asset Contribution Agreements"), Geon
and OxyChem will contribute certain assets (the "Contributed Assets"), stock,
and a partnership interest, together with certain related liabilities, to the
Partnerships (collectively, the "Contributed Businesses"). Geon will contribute
to the PVC Partnership five PVC suspension and mass resin plants and one VCM
plant, together with related assets, and all of the outstanding capital stock of
LaPorte Chemicals ("Geon's PVC Contributed Assets"). These plants had a nominal
base capacity in 1998 of 2.4 billion pounds of PVC and 2.4 billion pounds of
VCM. In exchange, Geon will receive a 24% interest in the PVC Partnership, and
the PVC Partnership will assume certain liabilities and obligations of Geon
aggregating $185 million, including the obligations of Geon under a lease
pursuant to which Geon leases a portion of a VCM plant located in LaPorte,
Texas, as well as certain industrial revenue bond debt of Geon. OxyChem will
contribute to the PVC Partnership one PVC plant, one VCM plant, a 50% interest
in OxyMar, a Texas general partnership that operates a VCM plant ("OxyMar"), and
a chlor-alkali chemical complex, together with related assets ("OxyChem's PVC
Contributed Assets"). These plants, including 50% of the capacity of OxyMar's
VCM plant in Ingleside, Texas, had a nominal base capacity in 1998 of 1.8
billion pounds of PVC and 2.3 billion pounds of VCM while the chlor-alkali
complex had a nominal base capacity in 1998 of 1.8 billion pounds of chlorine
and 2.0 billion pounds of caustic soda. In exchange, OxyChem will receive a 76%
interest in the PVC Partnership, and the PVC Partnership will assume certain
related liabilities and obligations of OxyChem, including certain OxyMar debt.
 
     Geon will contribute to the Compounding Partnership substantially all of
its powder/dry blend compounding assets and its powder compound business located
at Plaquemine, Louisiana ("Geon's Compounding Contributed Assets"). In exchange,
Geon will receive a 90% interest in the Compounding Partnership, and the
Compounding Partnership will assume certain liabilities and obligations of Geon.
OxyChem will contribute to the Compounding Partnership substantially all of its
compounding assets and powder compound manufacturing site located at Pasadena,
Texas ("OxyChem's Compounding Contributed Assets"). In exchange, OxyChem will
receive a 10% interest in the Compounding Partnership, and the Compounding
Partnership will assume certain liabilities and obligations of OxyChem.
 
     In conjunction with the Joint Venture Transactions, Geon will realize $110
million through the retention of certain working capital and the distribution of
cash from the PVC Partnership. OxyChem will also transfer to Geon a PVC flexible
film and pellet compounding plant located in Burlington, New Jersey (the
"Burlington Subject Business"), and its specialty pellet compound business
consisting of certain removable pelletizing equipment and personal property
primarily located in Pasadena, Texas, and inventory, customer lists, contracts
and other associated rights (the "Pasadena Subject Business").
 
     The following is a table reflecting the contributions of Geon and OxyChem
to each of the PVC and Compounding Partnerships.

     The results for the 21 month period set forth above are not likely to be
reliable predictors of operating income over the length of a full future
business cycle. Such results do not necessarily correspond to current operating
results for the Geon and OxyChem contributed businesses and were not the basis
for the parties' ownership share negotiations. The parties' respective ownership
percentages represent the parties' respective operating income contributions
over prior business cycles.
 
   
     The total operations to be transferred by OxyChem to Geon consist of
OxyChem's Compounding Contributed Business and the Burlington and Pasadena
Subject Businesses. The net income (loss) of the transferred businesses to Geon
for the nine months ended September 30, 1998, and year ended December 31, 1997,

     See the Unaudited Pro Forma Condensed Consolidated Financial Statement on
pages 13 through 24 of the Proxy Statement for a description of the impact of
the proposed transactions. See pages 31 through 36 regarding the opinion of the
financial advisor as to the fairness of the proposed transactions.
    
 
     Reasons for the Joint Venture Transactions. Geon believes that the Joint
Venture Transactions represent a logical extension of Geon's strategic plans to
enhance stockholder value by creating a stronger company with a redirected focus
as an international performance polymer and services company with the potential
for greater earnings growth and reduced commodity earnings volatility. Geon
expects that the Joint Venture Transactions will create in the PVC Partnership a
low-cost producer of PVC resins capable of competing effectively in the highly
competitive PVC resins industry. We also believe that the Joint Venture
Transactions will result in improved product and service offerings to customers
which, in turn, will likely enhance their value in their respective market
places. The goal of the Partnerships will be to improve long-term cash flow and
economic value through the safe and efficient operation of their respective
businesses and assets. As a result of the Joint Venture Transactions, Geon
expects that over time the Partnerships will achieve significant cost benefits
and savings compared to the combined cost to Geon and OxyChem of operating the
Contributed Businesses separately.

     Recommendation of the Geon Board of Directors. THE GEON BOARD BELIEVES THAT
THE JOINT VENTURE TRANSACTIONS ARE FAIR TO GEON AND IN ITS BEST INTEREST AND
UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" THE JOINT VENTURE TRANSACTIONS.
 
     Opinion of Financial Advisor to Geon. In deciding to approve the Joint
Venture Transactions, the Geon Board considered the opinion dated December 22,
1998, of its financial advisor, J.P. Morgan Securities Inc. ("J.P. Morgan"). The
opinion, which is based upon and subject to the considerations set forth
therein, states that as of the date of such opinion, the interest and other
consideration proposed to be received by Geon in the Joint Venture Transactions
in exchange for the components of the business or assets to be contributed by
Geon to the Partnerships was fair to Geon from a financial point of view. This
opinion is attached as Annex A to this Proxy Statement. WE ENCOURAGE YOU TO READ
THIS OPINION CAREFULLY.
 
     Certain Consequences of the Joint Venture Transactions. After the closing
of the Joint Venture Transactions, Geon will continue to exist in accordance
with the current provisions of its Certificate of Incorporation and Bylaws. The
businesses retained by Geon following the Joint Venture Transactions will
include Geon's vinyl compounding (other than powder/dry blend compounding),
specialty resin, and plastisol formulation businesses. These retained
businesses, together with Geon's interest in each of the Partnerships, will form
the platform from which Geon will seek to become an international performance
polymer and service company with the potential for greater earnings growth and
reduced commodity earnings volatility. Geon will also retain its 50% equity
interest in the Sunbelt Chlor Alkali Partnership, a joint venture with Olin
Corporation, and its 37.4% equity interest in Australian Vinyls Corporation, a
joint venture with Orica, Ltd. of Melbourne, Victoria, Australia. These retained
businesses, along with the consolidated sales of the Compounding Partnership,
are expected to have sales in 1999 of $1.2 billion.
 
     Following the Joint Venture Transactions, Geon will cease operating the PVC
suspension and mass resin business it contributed to the PVC Partnership and
will participate in the PVC Partnership only through its wholly-owned subsidiary
which will own a 24% interest in the PVC Partnership. In addition, as a result
of the Joint Venture Transactions, Geon will no longer own the powder
compounding assets that it contributed to the Compounding Partnership. However,
through its wholly-owned subsidiaries who are partners in the Compounding
Partnership, Geon will manage the operations of the Compounding Partnership.
 
     After the closing, holders of Geon Common Stock will continue to have their
voting rights with respect to their shares. However, stockholders will not have
the right to directly vote in favor of, or against, the representatives chosen
by Geon to serve on the Partnership Governance Committees of the Partnerships.
Geon's Chief Executive Officer will appoint such representatives.
 
     Accounting Treatment. Effective as of the closing, Geon will account for
its limited partnership interest in the PVC Partnership on an equity basis and
will account for its general partnership interest and limited partnership
interest in the Compounding Partnership by recording the net assets contributed
by OxyChem at their fair value and consolidating the results of the Compounding
Partnership adjusted for OxyChem's minority interest. This accounting treatment
is reflected in the pro forma financial statements of Geon that are included in
this Proxy Statement.
 
     Federal Income Tax Consequences. The Joint Venture Transactions will have
no federal income tax consequences for the stockholders of Geon. Geon is not
expected to recognize gain or loss for federal income tax purposes as a result
of the Joint Venture Transactions.
 
   
THE TRANSACTION DOCUMENTS (Pages 48-87)
    
 
     The Joint Venture Transactions are set forth in detail in nine separate but
interrelated agreements consisting of the Master Transaction Agreement (the
"Master Agreement"), the Asset Contribution
 
                                        4
<PAGE>   16
 
Agreements, a Partnership Agreement for each Partnership and a Parent Agreement
for each Partnership.
 
     The Master Agreement is a roadmap that describes each party's rights and
responsibilities in connection with the Joint Venture Transactions. In addition,
it contains (i) covenants governing the interim conduct of the contributed
businesses of Geon and OxyChem prior to the closing of the Joint Venture
Transactions, (ii) conditions precedent to each of Geon's and OxyChem's
obligations to consummate the Joint Venture Transactions, and (iii) provisions
for terminating the Joint Venture Transactions. The Master Agreement is attached
as Annex B to this Proxy Statement. See "The Master Transaction Agreement."
 
     The Asset Contribution Agreements for each of Geon and OxyChem with respect
to each Partnership set forth (i) the assets being transferred to, and
liabilities being assumed by, such Partnership, (ii) the representations and
warranties being made by each of Geon and OxyChem, and (iii) the indemnification
obligations of Geon, OxyChem, and such Partnership. See "The PVC Asset
Contribution Agreements" and "The Compounding Asset Contribution Agreements."
 
     The Partnership Agreement of each Partnership contains (i) the ownership
interest being received by each of Geon and OxyChem in such Partnership, (ii)
provisions for the governance of such Partnership, including actions requiring
approval of the representatives of both Geon and OxyChem and the development of
a strategic plan, (iii) the terms and conditions for the distributions of
profits and losses, and (iv) restrictions on the transfer and pledging of
membership interests by each partner. See "The PVC Partnership Agreement" and
"The Compounding Partnership Agreement."
 
     The Parent Agreement of each Partnership contains restrictions on the
transfer and pledging of the respective interests of Geon and OxyChem in the
general and limited partners of the Partnerships. In addition, the Compounding
Parent Agreement contains restrictions on Geon, OxyChem and OPC with respect to
certain business opportunities and certain standstill provisions. See "The
Parent Agreements."
 
   
GOVERNANCE (Pages 60 and 74)
    
 
     PVC Partnership. The executive officers of the PVC Partnership will manage
the day-to-day operations of the PVC Partnership under the supervision of a
Partnership Governance Committee (the "PVC Partnership Governance Committee").
The PVC Partnership Governance Committee will act much like a board of directors
of a corporation. The PVC Partnership Governance Committee will have six
members, three of whom Geon will appoint and three of whom OxyChem will appoint.
 
     Generally, OxyChem will control the operations and decision-making of the
PVC Partnership. However, Geon will have certain protective rights which would
preclude OxyChem from taking unilateral action on certain matters. Such matters
include changes in the scope of the PVC Partnership's business, approval of the
annually updated five-year strategic plan that will define the business goals
and strategy of the PVC Partnership, and sales or purchases of assets outside
the ordinary course of business or capital expenditures of more than $25 million
that are not contemplated by the then-current strategic plan.
 
     Compounding Partnership. A wholly-owned subsidiary of Geon, which will be
the general partner of the Compounding Partnership, will manage the day-to-day
operations of the Compounding Partnership under the supervision of a Partnership
Governance Committee (the "Compounding Partnership Governance Committee"). The
Compounding Partnership Governance Committee will act much like a board of
directors of a corporation. The Compounding Partnership Governance Committee
will have four members, two of whom Geon will appoint and two of whom OxyChem
will appoint.
 
     Generally, Geon will control the operations and decision-making of the
Compounding Partnership. However, OxyChem will have certain protective rights
which would preclude Geon from taking unilateral action on certain matters. Such
matters include changes in the scope of the Compounding Partner-
 
                                        5

ship's business, approval of the annually updated three-year strategic plan that
will define the business goals and strategy of the Compounding Partnership, and
sales or purchases of assets outside the ordinary course of business or capital
expenditures of more than $2 million that are not contemplated by the
then-current strategic plan.
 
CONDITIONS TO THE JOINT VENTURE TRANSACTIONS
 
     The respective obligations of Geon and OxyChem to effect the Joint Venture
Transactions are subject to a number of conditions agreed to in the Master
Agreement, including the following:
 
      (i) approval of the Joint Venture Proposal by Geon's stockholders;
 
      (ii) no legal restraints or prohibitions will exist which will prevent the
           completion of the Joint Venture Transactions, limit the operation of
           the business of the Partnerships or limit the ownership of the
           Partnerships or the Contributed Businesses;
 
     (iii) no events will have occurred which are likely to have a material
           adverse effect of the businesses contributed by Geon and OxyChem,
           except for events that effect the entire industry and affect the two
           businesses in a similar way; and
 
     (iv) obtaining certain consents of third parties.
 
TERMINATION OF THE JOINT VENTURE TRANSACTIONS
 
     The Boards of Directors of Geon and OxyChem can jointly agree to terminate
the Master Agreement and abandon the Joint Venture Transactions at any time
prior to closing. Either Geon or OxyChem, acting alone, can terminate the Master
Agreement and abandon the Joint Venture Transactions under certain
circumstances, including the following:
 
      (i) the non-terminating party made certain misrepresentations in the
          Master Agreement or does not honor certain covenants in the Master
          Agreement;
 
      (ii) either Geon's or OxyChem's Board of Directors has not duly authorized
           and approved the Master Agreement and certain related agreements and
           the transactions contemplated thereby on or before May 1, 1999;
 
     (iii) a court or governmental authority has prohibited the Joint Venture
           Transactions; or
 
     (iv) the closing does not occur on or before July 1, 1999.
 
OWNERSHIP OF GEON COMMON STOCK BY CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
   
(Pages 91-93)
    
 
   
     Directors and executive officers of Geon and its affiliates beneficially
owned 1,146,533 shares of Geon Common Stock or 4.72% of the shares of Geon
Common Stock outstanding on the Special Meeting Record Date.
    
 
                                  RISK FACTORS
 
LACK OF CONTROL OVER DELIVERY AND QUALITY OF PVC AND VCM
 
     Currently, Geon internally produces most of the PVC and VCM it uses to
manufacture its PVC compounds and specialty resins. As a result, Geon has full
control over the delivery and quality of these raw materials. Following the
Joint Venture Transactions, the PVC Partnership and OxyChem, through its
ownership interest in the PVC Partnership, will control the delivery and quality
of PVC and VCM used by Geon in its business. Geon will source most of its PVC
resin requirements and all of its VCM requirements through long-term contracts
with the PVC Partnership. See "Certain Related Party Transactions." If the PVC
Partnership is unable to perform its obligations under those contracts, Geon may
be
 
                                        6
<PAGE>   18
 
forced to purchase some or all of its requirements from other sources on terms
that may be less favorable than the terms of the supply contracts with the PVC
Partnership and that may be less favorable than Geon's internal supply
arrangements prior to the Joint Venture Transactions. If that happened, because
Geon will no longer be producing VCM and PVC for its own use, Geon's continuing
operations, excluding its investment in the PVC Partnership, may also be more
vulnerable to the fluctuations in the pricing of PVC.
 
RELINQUISHMENT OF DAY-TO-DAY CONTROL OF THE ASSETS BEING CONTRIBUTED TO THE PVC
PARTNERSHIP
 
     As a result of the Joint Venture Transactions, Geon will give up control
over a significant portion of its historical business. Geon will no longer
control the day-to-day operations and decision-making of the PVC resins and
intermediates assets, raw material procurement, businesses and systems it is
contributing to the PVC Partnership. In addition, Geon will no longer be
directly involved in the business relationships with customers who, prior to the
Joint Venture Transactions, purchased only PVC from Geon. Instead, the PVC
Partnership and OxyChem, through its interest in the PVC Partnership, will
control such assets, businesses, and business relationships. Although Geon will
have certain protective rights which would preclude OxyChem from taking
unilateral action on certain significant matters, action on other matters may
adversely impact Geon's equity interest. See "The PVC Partnership
Agreement -- Unanimous Voting Requirements."
 
RELINQUISHMENT OF FULL CONTROL OVER INVESTMENT DECISIONS AND DIVIDEND POLICY OF
THE PVC PARTNERSHIP
 
   
     After the completion of the Joint Venture Transactions, Geon will no longer
have full control over the investment and reinvestment decisions of its PVC
suspension and mass resin and intermediates business. These decisions will be
shared by Geon and OxyChem. While Geon and OxyChem currently agree on the
general plans for the PVC Partnership, Geon and OxyChem may disagree in the
future on business plans of the PVC Partnership with respect to expansion,
reinvestment, and dividend policies. In particular, approval of two
representatives of each of Geon and OxyChem is required to, among other things:
(a) cause the PVC Partnership to engage or invest in any business outside the
scope of its PVC suspension and mass resin and intermediates business; (b)
dispose of assets outside the ordinary course of business having a fair market
value of over $50 million; (c) authorize any acquisition of assets outside the
ordinary course of business or any capital expenditure exceeding $25 million;
(d) require capital contributions to the PVC Partnership within any fiscal year
if the total of such contributions from the partners exceeds $10 million; (e)
make PVC Partnership distributions not contemplated by the strategic plan or the
cash management and credit and deposit facilities agreement; or (f) merge with
or into another entity. If Geon and OxyChem disagree on whether the PVC
Partnership should take any of these actions, the necessary approval will not be
obtained, and the PVC Partnership will not be able to take such action. For a
more complete list of the actions which require the approval of both Geon and
OxyChem see "The PVC Partnership Agreement -- Unanimous Voting Requirements." In
addition, if after the fifth anniversary of the PVC Partnership Agreement, the
parties cannot agree upon and approve an updated strategic plan, one of the
parties may elect to dissolve the PVC Partnership. See "The PVC Partnership
Agreement -- Strategic Plans, Annual Budgets, and Expenses" and " -- Dissolution
and Termination."

     The complete 1998 fourth quarter financial operating results for the
OxyChem Transferred Businesses are not available. The 1998 fourth quarter
financial operating results for the OxyChem transferred PVC and VCM business are
expected to be consistent with the previous quarters in 1998, except as
identified below. The fourth quarter sales volume and average margin of PVC
resin (PVC selling price less ethylene and chlorine market costs) remained
constant. However, OxyChem's Houston chlor-alkali business experienced a decline
in operating earnings in the fourth quarter of 1998, primarily driven by lower
chlorine prices. The chlorine price declined $25 per ton reducing earnings by an
estimated $5 million based on OxyChem's internal corporate variance analysis for
the fourth quarter compared to the third quarter and $78 per ton reducing
earnings by an estimated $17 million based on OxyChem's internal corporate
variance analysis for the nine month average year-to-date September 1998
pricing. There were no significant sales volume changes in the fourth quarter
compared to the previous periods.
    
 
   
     Based on recent forecast data by Chemical Market Associates Inc. ("CMAI")
World Vinyls Analysis, an annual publication by a major petrochemical tracking
firm, the PVC Partnership is projected to benefit from an approximately 1.0 cent
per pound or $40 million increase in the average margin of PVC resin selling
prices over ethylene and chlorine market costs in 1999 as compared to 1998.
However, CMAI forecasts lower average chlor-alkali electrochemical unit prices
and margins of approximately $105 per ton or $95 million in 1999 versus 1998.
The PVC Partnership is also projected to benefit an estimated $30 million in
1999 from a full year of an anhydrous hydrogen chlorine supply contract with
Bayer Corporation and improved ethylene supply agreements. In addition, some
portions of the synergies described in this Proxy Statement are anticipated to
be realized in 1999, and higher demand is projected to improve manufacturing
capacity utilization. The net impact of these projected variables in 1999 is
minimal, resulting in 1999 projected operating earnings of the PVC Partnership
approximating the pro forma 1998 results for the nine months of 1998 shown on
page 18, plus the 1998 fourth quarter results above.

(a) Reflects an extraordinary loss on early extinguishment of debt which reduced
    net income by $1.3 million in 1994.
 
(b) Reflects the cumulative effect of a change in method of accounting for post
    retirement benefits which reduced net income by $1.1 million in 1993.
 
(c) On February 11, 1993, Geon was formed as a wholly owned subsidiary of The
    BFGoodrich Company ("BFG") in preparation for the initial public offering of
    its common stock on April 29, 1993. BFG transferred to Geon substantially
    all of the operating assets and liabilities of its Geon Vinyl Division,
    other than the net assets of the chlor-alkali, ethylene and utility
    operations of BFG located principally at Calvert City, Kentucky (the
    "Calvert Facilities"), in exchange for Geon's common stock.
 
    The historical results for 1993 include the results of operations associated
    with the Calvert Facilities through February 28, 1993. The cost of VCM
    consumed from the Calvert Facilities was recorded at historical intercompany
    cost through April 29, 1993.
 
(d) The pro forma results for 1993 exclude the results of operations associated
    with the Calvert Facilities. The data is also presented as if Geon purchased
    the VCM associated with the Calvert Facilities at market prices rather than
    at historical intercompany costs. Subsequent to the initial public offering
    of Geon Common Stock on April 29, 1993, purchases of VCM from BFG were at
    market prices. The pro forma results also include the cost associated with
    certain May 1993 bank arrangements, as if they had occurred at the beginning
    of 1993.
 
    Historical earnings per share for 1993 have been omitted because until March
    1, 1993, Geon was a division of BFG and had no stock authorized, issued or
    outstanding. The 1993 unaudited pro forma earnings per share amounts were
    computed based on the weighted average number of shares of common stock
    outstanding and common stock equivalents. The pro forma computation through
    the date of the initial public offering includes all shares outstanding on
    completion of the initial public offering plus the dilutive effect of
    options at the time of the initial public offering.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
     The unaudited pro forma condensed consolidated financial statements of Geon
reflect the Joint Venture Transactions and related transactions as if they had
been completed on September 30, 1998, for pro forma balance sheet data purposes
and on January 1, 1997, for pro forma income statement data purposes. The
Unaudited Pro Forma Condensed Consolidated Statements of Income include amounts
derived from the audited Consolidated Statement of Income of Geon for the year
ended December 31, 1997, the Unaudited Condensed Consolidated Statement of
Operations of Geon for the nine months ended September 30, 1998, the Unaudited
Statements of Income of the Geon PVC Business for the year ended December 31,
1997, and the nine months ended September 30, 1998, the audited Combined
Statement of Operations of the OxyChem Transferred Businesses for the year ended
December 31, 1997, and the Unaudited Combined Statement of Operations of the
OxyChem Transferred Businesses for the nine months ended September 30, 1998. The
Unaudited Pro Forma Condensed Consolidated Balance Sheet includes amounts
derived from the Unaudited Condensed Consolidated Balance Sheet of Geon, the
Unaudited Condensed Balance Sheet of the Geon PVC Business, and the Unaudited
Combined Balance Sheet of the OxyChem Transferred Businesses as of September 30,
1998. OxyChem's transfer of its 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 will be
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 estimated after-tax gain of $57
million in the period in which the Joint Venture Transactions and related
transactions occur. Such contributions include, for accounting purposes, a sale
of 76% of Geon's PVC Contributed Business to OxyChem and a sale of 10% of Geon's
Compounding Contributed Business to OxyChem. The resultant gain represents the
excess of fair value (including the realization of a net $110 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.
 
     In the Unaudited Pro Forma Condensed Consolidated Financial Statements, the
following components comprise the net $110 million in cash and working capital
retention benefits:

     The Unaudited Pro Forma Condensed Consolidated Financial Statements of Geon
and the accompanying notes should be read in conjunction with the audited and
unaudited consolidated financial statements of Geon, the unaudited financial
statements of the Geon PVC Business, and the related notes thereto, and the
audited and unaudited combined financial statements of the OxyChem Transferred
Businesses, and related notes thereto, 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 Joint Venture Transactions 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. In addition, Geon's Unaudited
Pro Forma Condensed Consolidated Financial Statements do not reflect the
synergies or synergy costs expected to result from the Joint Venture
Transactions. As discussed elsewhere in this Proxy Statement, it is anticipated
that the PVC Partnership will capture up to $80 million annually (or the
equivalent of 2c per pound of PVC resin produced by the PVC Partnership) of
synergies. These synergies are expected to be fully realized by the year 2001.
It is anticipated that an aggregate of $18 million of costs and $45 million of
capital expenditures will be incurred by the Partnerships during the period 1999
through 2000 related to achieving the synergies. Geon expects its aggregate
share of the synergies resulting from the Partnerships to approximate $27
million and the costs of such synergies to approximate $7 million. See "The
Joint Venture Transactions -- Reasons for the Joint Venture Transactions."

NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED STATEMENTS OF INCOME (IN
MILLIONS):
 
   
     For the nine months ended September 30, 1998, Geon's pro forma net income
was $33 million, or $16.2 million above its historical net income for the
period. The Geon PVC Business had an operating loss for the nine months ended
September 30, 1998, of $28.6 million. This operating loss primarily results from
the historic low margins of the PVC industry. The industry conditions are more
fully discussed in the "Management's Discussion and Analysis of Financial
Condition and Results of Operations" section included in Geon's Quarterly Report
on Form 10-Q for the quarter ended September 30, 1998, included herein. Geon's
pro forma equity loss in the PVC Partnership is $.8 million, or $27.8 million
lower than the operating loss of the Geon PVC Business. This lower pro forma
loss resulting from the PVC Partnership primarily reflects the relative higher
year-to-date operating margins of OxyChem's chlor-alkali business. However, the
margins in the chlor-alkali industry have decreased considerably during the
second half of 1998.
    
 
     The 1997 pro forma net income includes special pre-tax charges taken by
Geon of $11.9 million for employee separation and $32.8 million for asset
impairments reported by the Acquired Businesses. Excluding these special
charges, pro forma net income would have been $27.9 million or $1.18 of earnings
per diluted share.
 
          (a) To reflect the sum of Geon's 24% share of the pro forma PVC
     Partnership income 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 earnings from the PVC
     Partnership have also been reduced 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 income is computed as follows:

          (m) In 1997, Geon recorded certain adjustments to its prior year's
     income tax liability which reduced Geon's effective income tax rate to 35%
     for the year ended December 31, 1997.
 
The Unaudited Pro Forma Consolidated Statements of Income do not reflect the
following:
 
             (i) The one time after tax gain of $57 million resulting from
        Geon's contributions to the PVC Partnership and the Compounding
        Partnership, which for accounting purposes are treated as a sale of 76%
        of Geon's PVC Contributed Businesses to OxyChem and a sale of 10% of
        Geon's Compounding Contributed Business to OxyChem. The resultant gain
        represents the excess of fair value (including cash received of $76
        million) over the book value of the 76% and 10% of Geon's PVC and
        Compounding Contributed Businesses, respectively.
 
   
     Such gain is net of certain one-time costs directly related to the
formation of the PVC Partnership and Compounding Partnership as follows:

             (ii) The synergies and the cost of such synergies expected to be
        realized by Geon as a result of the Joint Venture 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 Geon's
        consolidation of its compounding operations.
 
   
             In the fourth quarter of 1998, Geon recorded employee separation
        and plant phase out charges of $14.6 million relating to Geon's
        consolidation of its compounding operations. This plan of consolidation
        includes the closing of two manufacturing plants and the partial closing
        of production lines at other manufacturing plants. The affected
        facilities are those of the former Synergistics operations that Geon
        acquired in the fourth quarter of 1997. The manufacturing of products
        made at such sites will be transferred to other plants utilizing
        existing capacity. The consolidation resulted in the write-off of
        software, machinery and equipment and, at the affected sites, employee
        separation costs related to the elimination of approximately 250
        positions, and charges related to other costs associated with the plant
        sites consisting primarily of demolition and lease termination costs.
        The charges taken in the fourth quarter of 1998 and those anticipated to
        be taken in the first quarter of 1999 related to the elimination of 250
        positions relate to termination costs (severence benefits and
        outplacement services). The costs associated with services rendered by
        the employees through the date of termination will be charged to
        operations as incurred.
    
 
   
             The fourth quarter 1998 activity relating to the accrual for the
        consolidation of the compound operations consisted of payments of $.7
        million and charges totaling $14.6 million as follows:
    
 
   
             (a) the non-cash write-off of fixed assets with a net book value of
        $5.3 million. Such fixed assets will be demolished by June 1999;
    
 
   
             (b) employee separation costs of $5.0 million of which cash
        payments of $.7 million were made as of December 31, 1998, and the
        remaining cash payments will be made through mid-2000. No employee
        terminations occurred through December 31, 1998. Termination of 180
        individuals is expected to be completed by mid-1999, in connection with
        the elimination of the 250 positions described above; and
    
 
   
             (c) other site closure costs of $4.3 million consisting of $3.3
        million of accrued demolition costs and $1.0 million of incurred legal
        and professional fees.
    
 
   
             Geon also anticipates incurring, in the first quarter of 1999 and
        upon formation of the powder compound joint venture, estimated costs
        totaling $7.5 million relating to the completion of the compound
        consolidation plan. The amounts expected to be incurred are as follows:
        (a) accelerated depreciation of $1.4 million and related disposition
        costs of $2.0 million related to certain compounding operating assets
        which were identified at the end of the fourth quarter of 1998 as assets
        to be taken out of service by the end of the second quarter of 1999, (b)
        lease termination costs of $.1 million, and (c) 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 in connection with the elimination of the
        250 positions discussed above. These terminations are expected to be
        completed by mid-1999. All sites and production lines in the plan are
        projected to be closed by mid-1999.
    
 
             The consolidation is expected to produce total cost savings of $6
        million in 1999 and $14 million annually thereafter.

                              THE SPECIAL MEETING
 
   
     We are providing this Proxy Statement to the stockholders of Geon in
connection with the solicitation by the Geon Board of proxies to be used at the
Special Meeting of the stockholders to be held on Monday, April 19, 1999, at
9:00 a.m., Eastern Standard Time, at The Fountaine Bleau Party Center, 635
Miller Road, Avon Ohio, and any adjournment thereof. This Proxy Statement is to
inform the stockholders of Geon of the matters to be acted upon at the Special
Meeting. Geon is mailing the Notice of Special Meeting of Stockholders, this
Proxy Statement, and the form of Proxy on or about March 29, 1999, to
stockholders of record on March 23, 1999. Geon's headquarters are located at One
Geon Center, Avon Lake, Ohio 44012, and Geon's telephone number is (440)
930-1000.
    
 
PURPOSE OF THE SPECIAL MEETING
 
     At the Special Meeting, Geon will ask its stockholders to consider and vote
upon the Joint Venture Proposal. Section 271 of the Delaware General Corporation
Law (the "DGCL") requires that a "sale, lease or exchange" of "all or
substantially all" of the assets of a Delaware corporation be approved by the
stockholders of the corporation. Geon is a Delaware corporation. Although there
is some uncertainty under the statute and case law as to the applicability of
Section 271 to the Joint Venture Transactions, Geon assets to be contributed to
the PVC Partnership and the Compounding Partnership are in the aggregate
significant. Geon does not believe that the Joint Venture Transactions
constitute the "sale, lease or exchange" of "all or substantially all" of Geon's
assets. In the absence of controlling authority as to the meaning of these terms
in the context of transactions like the Joint Venture Transactions, and as a
matter of good corporate governance, Geon has conditioned its obligation to
consummate the Joint Venture Transactions upon, among other things, the approval
of the Joint Venture Proposal by Geon stockholders holding at least a majority
of the Record Shares. See "The Master Transaction Agreement -- Conditions to
Closing".
 
     The Geon Board has further retained discretion, even if stockholder
approval of the Joint Venture Proposal is obtained and the other conditions to
the Joint Venture Transactions are satisfied, to abandon, defer, or modify the
Joint Venture Transactions or any other element contained in the Joint Venture
Proposal. If the Geon Board takes any such action, it will be on the basis that
the Geon Board believes such action will be in the best interests of Geon and
its stockholders.
 
     If the Geon Board modifies the terms of the Joint Venture Transactions and
concludes that such modifications are not material, Geon does not believe that
it is necessary to resolicit stockholder approval of the transactions.
Immaterial modifications will not fundamentally alter the character of the Joint
Venture Transactions. If the Geon Board modifies the Joint Venture Transactions
and such modifications in the aggregate are material, Geon will resolicit
stockholder approval. Under such circumstances, Geon will circulate revised
proxy materials to you.
 
     At the Special Meeting, Geon will also ask its stockholders to adopt The
Geon Company 1999 Incentive Stock Plan (the "1999 Stock Plan").
 
     THE GEON BOARD HAS UNANIMOUSLY APPROVED THE JOINT VENTURE TRANSACTIONS AND
ADOPTED THE 1999 STOCK PLAN AND UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE
"FOR" EACH OF THE PROPOSALS DESCRIBED IN THIS PROXY STATEMENT.
 
VOTING RIGHTS AND VOTE REQUIRED
 
   
     Only Geon stockholders as of the close of business on the Special Meeting
Record Date are entitled to receive notice of and to vote at the Special
Meeting. Except for shares owned by Geon, each share of Geon Common Stock
outstanding at the close of business on the Special Meeting Record Date is
entitled to one vote at the Special Meeting. As of the Special Meeting Record
Date, there were 23,478,010 shares of Geon Common Stock issued and outstanding
and entitled to vote at the Special Meeting. The representation in person or by
proxy of at least a majority of Record Shares is necessary to provide a quorum
at the meeting.
    
 
                                       25
<PAGE>   37
 
     The affirmative vote of at least a majority of the Record Shares is
required for approval of the Joint Venture Proposal. The affirmative vote of the
holders of at least a majority of the votes cast (including abstentions) is
required for the approval of the Stock Plan Proposal. The Geon Board has
unanimously recommended approval of the Joint Venture Proposal and the Stock
Plan Proposal.
 
     Abstentions and "broker non-votes" are counted as present in determining
whether the quorum requirement is satisfied. A "broker non-vote" occurs when a
broker or other nominee holding shares for a beneficial owner votes on one
proposal but does not vote on another proposal. Abstentions will not be voted.
Broker non-votes will not be counted as votes cast on any matter to which they
relate. Abstentions and broker non-votes will have the effect of votes cast
against such proposals.
 
PROXIES
 
     If you attend the Special Meeting, you may vote your shares by ballot. If
you do not attend, you may still vote your shares by proxy at the Special
Meeting if you sign and return the enclosed proxy card. Geon Common Stock
represented by a properly signed card will be voted in accordance with the
choices marked on the card. If no choices are marked, the shares will be voted
in favor of the Joint Venture Proposal and the Stock Plan Proposal. You may
revoke your proxy before it is voted by giving notice to Geon in writing or
orally at the meeting. Participants in Geon's Retirement Savings Plan will
receive a separate voting instruction card which must be signed and returned in
order to instruct the trustee of that plan regarding the manner in which to vote
the shares held under that plan by the trustee. Such participants may revoke
their voting instructions before the trustee votes the shares held by it by
giving notice in writing to the trustee.
 
     The Geon Board has designated William F. Patient, Chairman of the Board and
Chief Executive Officer of Geon, and Gregory L. Rutman, Vice President, General
Counsel and Secretary of Geon, as proxies for appointment by stockholders to
represent and vote their shares in accordance with their directions.
 
     If a quorum is not present at the time the Special Meeting is convened, or
if Geon believes that additional time should be allowed for the solicitation of
proxies or for any other reason, Geon may adjourn the Special Meeting from time
to time upon a vote of the stockholders. If Geon proposes any adjournment of the
Special Meeting by a vote of the stockholders, the persons named in the enclosed
form of proxy will vote all shares of Geon Common Stock for which they have
voting authority in favor of such adjournment.
 
COSTS OF SOLICITATION
 
   
     Geon is making this proxy solicitation and will bear the expense of
preparing, printing and mailing the Notice of Special Meeting of Stockholders
and this Proxy Statement. In addition to requesting proxies by mail, officers
and regular employees of Geon may request proxies by telephone or in person.
Geon has retained Morrow & Co., Inc., 445 Park Avenue, New York, New York 10022
to assist in the solicitation for an estimated fee of $7,500 plus reasonable
expenses. Geon will ask custodians, nominees, and fiduciaries to send proxy
material to beneficial owners in order to obtain voting instructions. Geon will,
upon request, reimburse them for their reasonable expenses for mailing the proxy
material.
    
 
                  PROPOSAL ONE: THE JOINT VENTURE TRANSACTIONS
 
                         THE JOINT VENTURE TRANSACTIONS
 
BACKGROUND FOR THE JOINT VENTURE TRANSACTIONS
 
     On December 3, 1997, William F. Patient, Chairman and Chief Executive
Officer of Geon, along with Thomas A. Waltermire, President and Chief Operating
Officer, and other members of Geon's management ("Management") made a
presentation to the Geon Board concerning the strategic direc-
 
                                       26
<PAGE>   38
 
tion of Geon. Specifically, Management reviewed with the Geon Board strategy
discussions held during early 1997 which led to the new strategic vision of
creating a company focused on performance polymers and services. The Geon Board
reviewed matters relating to stockholder value maximization and structural
issues related to the PVC resins business. The Geon Board recommended that Geon
take steps to separate the PVC and VCM businesses from the rest of Geon,
recapturing Geon's investment in an appropriate fashion, and pursue the strategy
of building the performance polymers and services' segments.
 
     Chuck Mears, Executive Vice President of OxyChem's Chlorovinyls group,
called Mr. Waltermire on or about January 14, 1998, to inquire if Geon would be
willing to discuss a possible combination of Geon's and OxyChem's PVC suspension
and mass resins and intermediates businesses. On January 16, 1998, Mr. Patient
called J. Roger Hirl, President and Chief Executive Officer of OxyChem, to
discuss OxyChem's interest in a possible transaction with Geon involving their
respective PVC resins and intermediates businesses. On January 21, 1998, OxyChem
and Geon entered into a secrecy agreement.
 
     On February 4, 1998, Management informed the Geon Board of the contacts
made with OxyChem concerning a proposed transaction involving the PVC suspension
and mass resins and intermediates businesses of Geon and OxyChem. The Geon Board
directed Management to pursue the initial contacts on behalf of Geon and to
report developments.
 
     On February 9, 1998, Messrs. Patient and Waltermire, along with W. David
Wilson, Geon's Chief Financial Officer, and Gregory L. Rutman, General Counsel
for Geon, accompanied by outside counsel, met in Houston, Texas, with Messrs.
Hirl and Mears, Rich Lorraine, OxyChem's Chief Financial Officer, Stephen I.
Chazen, Executive Vice President of OPC, and Keith McDole, General Counsel for
OxyChem, who were accompanied by OxyChem's outside antitrust counsel. At that
meeting, the parties discussed their mutual interest in forming a joint venture
to operate their PVC suspension and mass resins and intermediates businesses
that would achieve certain synergies. The parties also discussed the potential
synergies, including cost savings and manufacturing efficiencies. In addition,
the parties reviewed legal considerations related to the formation of a joint
venture and determined the next steps to be taken in the process.
 
     The Strategy Council for Geon met on February 19 and 20, 1998, in Tucson,
Arizona, to review strategic options available to Geon with regard to the resin
and intermediates business. As part of that meeting, the Strategy Council
discussed a proposed combination of Geon's and OxyChem's PVC suspension and mass
resins and intermediates businesses.
 
     On March 16, 1998, representatives of Geon and OxyChem met and Geon
presented Geon's vision of the proposed transaction. At this meeting, Geon
expressed an interest in purchasing OxyChem's PVC compound business. On April
16, the representatives of each party met again. During that meeting, they
discussed the structure of the proposed joint venture involving the PVC
suspension and mass resins and intermediates businesses.
 
     From March through mid-May 1998, representatives of Geon and OxyChem
exchanged information and held meetings focused on the value of the potential
synergies that might be achieved through a combination of their PVC resins and
intermediates businesses, proposed valuation models, historical results,
financial and operating data, and possible structures.
 
     On May 6, 1998, at a meeting of the Geon Board, Mr. Patient updated the
Geon Board on the status of the discussions with OxyChem relating to the
possible transaction.
 
     On May 12, 1998, the management of Geon and OxyChem met in Cleveland, Ohio.
At this meeting, the parties discussed further the formation of a joint venture
to operate their PVC suspension and mass resins and intermediates business and
continued discussions relating to the future of OxyChem's compounding businesses
including its powder/dry blend compound business. The parties discussed which
facilities might be included in the PVC resin joint venture and the governance
structure of that joint venture. At this meeting, OxyChem also disclosed to Geon
that it was selling the Burlington Subject
                                       27
<PAGE>   39
 
Business. Given that the Burlington Subject Business was within the scope of
Geon's strategic plan, Geon stated that it desired to purchase that business.
 
     Between May 12, 1998, and May 22, 1998, the parties concluded that the
Pasadena Subject Business should be transferred to Geon and that the parties
should form a joint venture to operate their powder/dry blend compounding
businesses. OxyChem desired to maintain an interest in the powder/dry blend
compound market. Geon believed that an OxyChem minority interest in a powder/dry
blend compound joint venture was advantageous since some of the potential
customers of the PVC resin joint venture would also require powder/dry blend
compound.
 
     During the next meeting held on May 22, 1998, the parties agreed to pursue
detailed negotiations with respect to two joint ventures and reached preliminary
agreement on their respective ownership percentages.
 
     During the week of June 15, 1998, the parties held meetings in Dallas,
Texas, to negotiate and finalize the terms of a proposed Letter of Intent.
 
     On June 22, 1998, at a special meeting of the Geon Board, the Geon Board
authorized Geon to enter into the proposed Letter of Intent negotiated between
the parties. On June 24, 1998, the Letter of Intent was signed and announced to
the public.
 
     Throughout the period from June 24, 1998, through December 18, 1998, the
parties performed due diligence and representatives of Geon and OxyChem held a
series of meetings and discussions to negotiate the terms of the Master
Agreement, the Asset Contributions Agreements, the Partnership Agreements, the
Parent Agreements, and numerous other supply and transition services agreements
and to discuss tax considerations and proposed management and human resources
issues.
 
     During this period, Management updated the Geon Board on the progress of
negotiations with OxyChem at its meetings held in August and November 1998.
Management delivered a comprehensive presentation of the Joint Venture
Transactions to the Geon Board at its meeting held on December 3, 1998.
 
     On December 18, 1998, Geon and OxyChem executed the Master Agreement to be
effective on December 22, 1998. At a meeting held on December 22, 1998, the Geon
Board considered and unanimously approved the Joint Venture Transactions.
 
REASONS FOR THE JOINT VENTURE TRANSACTIONS
 
     Generally. Geon believes that the Joint Venture Transactions represent a
logical extension of its strategic plan to enhance stockholder value by creating
a stronger company with a redirected focus as an international performance
polymer and services company with the potential to have greater earnings growth
and reduced commodity earnings volatility. Management and the Geon Board believe
that it is in the best interests of Geon's stockholders to focus resources on
growing the higher value added performance polymer and services business
aggressively and that the PVC resins and intermediates business should be
partnered in order to increase its earnings growth and to provide a source of
capital to fund such growth. These beliefs are the result of considerable
analysis and deliberation on alternative portfolio strategies from which
Management concluded that (i) investing to grow the performance polymers and
services business provided an opportunity to build a company with a broader,
more value added business base that should create relatively higher stockholder
values and (ii) transforming Geon to capture such higher stockholder values
required the divestiture of a majority interest in the PVC resins and
intermediates business.
 
     Management concluded that building upon and growing the performance
polymers and services business would provide relatively higher returns to
stockholders. Management believes that this strategy complements Geon's core
strengths including (i) its compound product and process technology and
specialty resin and plastics formulation businesses, (ii) its understanding of
cost efficiencies and market drivers, and (iii) its business and financial
control processes. Management also believes that the performance polymers and
services business has certain desirable characteristics, such as (i) engendering
applications and new product development that will enhance primary demand
growth,
 
                                       28
<PAGE>   40
 
the value of which would be readily captured by Geon, (ii) serving markets where
the products offered can be differentiated by providing performance or service
advantages that are, to a greater degree, protectable, (iii) providing the
opportunity to enter new markets, and (iv) leveraging knowledge to facilitate
entry into markets with an array of polymer solutions broader than PVC based
compounds. Further, Management believes that focusing on the performance polymer
and service business will have a positive financial impact for Geon's
stockholders by providing more predictable earnings and reducing the volatility
and cyclicality in the earnings structure.
 
     Management concluded that in order to effect the transformation of Geon
efficiently and to capture the higher equity market valuation for Geon's
stockholders, Geon had to divest a majority interest in its PVC resins and
intermediates business. The Geon Board directed Management to assess various
alternative approaches to implement this strategy. A joint venture with another
PVC resin supplier, such as OxyChem, who could also provide sufficient upstream
raw material integration to balance sourcing requirements and with whom
substantial cost synergies were possible, was believed to be the most attractive
option.
 
     PVC Partnership. The PVC Partnership is expected to be a low-cost
manufacturer with substantial raw material resources, the financial strength to
grow to meet customer needs, and the ability to develop the best product and
process technologies. With its strong integration and the substantial synergies
expected to be achieved, Geon and OxyChem believe that the PVC Partnership will
be economically competitive with the best in the world.
 
     Geon and OxyChem believe that customers of the PVC Partnership will benefit
from the breadth of the product line offered, the companies' combined
technologies applied to customer requirements, and the economic strength of the
PVC Partnership which will be directed to supporting customer growth and
technology needs.
 
     Compounding Partnership. Geon expects the Compounding Partnership to be a
full-line PVC extrusion, dry blend/powder producer and marketer, with low-cost,
long-run capacity available to serve key customers of Geon and the PVC
Partnership. In addition, Geon expects the Compounding Partnership to have the
capability to produce short-run color and specialty dry blend/powders for
customers with specific needs. The combination enables cost efficient
consolidation of operations, reduced raw materials costs, and improved
administrative efficiencies. As a result, the Compounding Partnership is
expected to be able to support a broad range of customers effectively across a
wide spectrum of product and service needs.
 
   
     Synergies. Following the contribution of the Contributed Assets to each
Partnership, Geon and OxyChem expect each Partnership to realize significant
cost benefits and savings (the "Synergies") compared to the aggregate cost to
Geon and OxyChem of operating such assets and their related businesses
separately. Specifically, they anticipate the PVC Partnership will capture up to
$80 million annually (or the equivalent of 2c per pound of PVC resin produced by
the PVC Partnership) of Synergies, and the Compounding Partnership will capture
up to $8 million annually of Synergies. Geon expects its share of the Synergies
resulting from the PVC Partnership to approximate $20 million and its share of
the Synergies resulting from the Compounding Partnership to approximate $7
million. At the same time, Geon and OxyChem expect to maintain or improve
customer and technical support to the Partnerships' customers.
    
 
   
     With respect to the PVC Partnership, the anticipated $80 million of
Synergies include the various production efficiencies set forth in the table
below.

  PVC Partnership...........................................             5.0
</TABLE>
    
 
   
     Geon expects to create $7 million in Synergies with respect to the PVC
Partnership as a result of logistics, distribution, packaging, and inventory
efficiencies. The number of PVC resin distribution terminals is expected to be
reduced as well as the number of railcars employed by the PVC Partnership
through the optimization of Geon's and OxyChem's existing rail fleets. Overall,
inventories required to support the combined customer base will be reduced.
    
 
   
     Geon and OxyChem expect to create $14 million in Synergies by consolidating
staff services and insurance coverage. A single experienced executive management
team will manage the PVC Partnership rather than the two teams currently in
place at Geon and OxyChem. This consolidation is expected to (i) reduce or
eliminate duplicative overhead and staffing costs, (ii) consolidate Geon's and
OxyChem's sales, marketing, and logistics staffs, (iii) consolidate the research
and development facilities, (iv) consolidate legal, environmental, health and
safety, and risk management services, as well as achieve lower cost property and
liability insurance coverage, and (v) operate a common integrated information
system.
    
 
   
     Furthermore, the PVC Partnership has a unique opportunity to create $5
million in Synergies through the consolidation of plant services and support
groups associated with the PVC Partnership's Houston-area production facilities.
Rather than managing the five units as disparate facilities, the PVC Partnership
expects to manage the group as a single operating entity. In addition, the PVC
Partnership intends to implement numerous other initiatives that collectively
will result in $14 million of additional savings.
    
 
   
     The PVC Partnership expects to achieve $20 million of Synergies during the
remainder of 1999, a total of $75 million of Synergies by the end of 2000, and a
total of $80 million of Synergies by the end of 2001.
    
 
   
     Geon and OxyChem expect the formation of the Compounding Partnership to
result in Synergies similar to many of those that will be achieved through the
formation of the PVC Partnership. The parties anticipate $4 million of Synergies
as a result of manufacturing efficiencies related to the closure of Geon's
Conroe, Texas, facility, $2 million of Synergies as a result of volume
purchases, and $1 million of Synergies as a result of a reduction in redundant
sales, general, and administrative expenses. The parties preliminary estimate is
that the Compounding Partnership will be able to achieve Synergies in the range
of $7 to $8 million annually. All of the Compounding Partnership's Synergies are
expected to be realized by the end of 1999.
    
 
     In addition, the Joint Venture Transactions will result in one-time costs
of approximately $18 million, primarily as a result of severance and relocation
costs. Geon and OxyChem will bear these costs either in accordance with their
ownership percentages or equally, except for certain costs which each of Geon
 
                                       30
<PAGE>   42
 
and OxyChem will pay directly. Also, capital expenditures will have to be made
to obtain certain of the Synergies. It is currently anticipated that these
capital expenditures will be approximately $45 million. Geon expects its
aggregate share of the cost incurred by the Partnerships related to achieving
the Synergies to approximate $7 million.
 
RECOMMENDATION OF THE GEON BOARD
 
     At a meeting of the Geon Board held on December 22, 1998, the Geon Board
unanimously determined that the Joint Venture Transactions are in the best
interests of Geon and its stockholders, unanimously approved the Joint Venture
Transactions, and unanimously recommended that holders of Geon Common Stock vote
"FOR" approval of the Joint Venture Proposal.
 
OPINION OF FINANCIAL ADVISOR TO GEON
 
     Pursuant to an engagement letter dated November 13, 1998, Geon retained
J.P. Morgan to deliver a fairness opinion in connection with the proposed Joint
Ventures Transactions.
 
     At the meeting of the Geon Board on December 3, 1998, J.P. Morgan rendered
its oral opinion to the Geon Board that, as of such date, the interest and other
consideration proposed to be received by Geon in the Joint Ventures Transactions
(the "Received Consideration") in exchange for the components of the business or
assets to be contributed by Geon to the Partnerships (the "Contributed
Consideration") was fair from a financial point of view to Geon. J.P. Morgan has
confirmed its oral opinion by delivering a written opinion dated December 22,
1998, to the Geon Board to the same effect. No limitations were imposed by the
Geon Board upon J.P. Morgan with respect to the investigations made or
procedures followed by it in rendering its opinion.
 
     The full text of the written opinion of J.P. Morgan dated December 22,
1998, which sets forth the assumptions made, matters considered, and limits on
the review undertaken, is attached as Annex A to this Proxy Statement and is
incorporated herein by reference. Geon stockholders are urged to read the
opinion in its entirety. J.P. Morgan's written opinion is addressed to the Geon
Board, is directed only to the interest and consideration to be received in
connection with the Joint Venture Transactions, and does not constitute a
recommendation to any stockholder of Geon as to how such stockholder should vote
at the Special Meeting. The summary of the opinion of J.P. Morgan set forth in
this Proxy Statement is qualified in its entirety by reference to the full text
of such opinion.
 
   
     In arriving at its opinion, J.P. Morgan reviewed, among other things, the
Master Agreement and related agreements; the audited financial statements of
Geon and OPC for the fiscal year end December 31, 1997, and the unaudited
financial statements of Geon and OPC for the period ended September 30, 1998;
current and historical market prices of Geon's Common Stock and OPC's Common
Stock; certain publicly available information concerning the business of Geon
and OxyChem and of certain other companies engaged in businesses comparable to
those of the Partnerships; the terms of other business combinations deemed
relevant by J.P. Morgan; certain internal financial analyses and forecasts
prepared by Geon and its management; and certain agreements with respect to
outstanding indebtedness or obligations of Geon and OxyChem. J.P. Morgan did not
receive any forecasts prepared by OxyChem and its management. J.P. Morgan also
held discussions with certain members of the management of Geon and OxyChem with
respect to certain aspects of the Joint Venture Transactions, the past and
current business operations of Geon and OxyChem, the financial condition and
future prospects and operations of Geon and OxyChem, and certain other matters
believed necessary or appropriate to J.P. Morgan's inquiry. In addition, J.P.
Morgan visited certain representative facilities of Geon and OxyChem, reviewed
such other financial studies and analyses, and considered such other information
as it deemed appropriate for the purposes of its opinion.
    
 
     J.P. Morgan relied upon and assumed, without independent verification, the
accuracy and completeness of all information that was publicly available or that
was furnished to it by Geon and OxyChem or otherwise reviewed by J.P. Morgan,

MORGAN HAS NOT CONDUCTED ANY VALUATION OR APPRAISAL OF ANY ASSETS OR
LIABILITIES, NOR

HAVE ANY VALUATIONS OR APPRAISALS BEEN PROVIDED TO J.P. MORGAN. In relying on
financial analyses and forecasts provided to J.P. Morgan by Geon, J.P. Morgan
has assumed that they have been reasonably prepared based on assumptions
reflecting the best currently available estimates and judgments by Geon's
management as to the expected future results of operations and financial
condition of Geon. J.P. Morgan has also assumed that the Joint Venture
Transactions will have no tax consequences to Geon as described in discussions
with, and materials furnished to J.P. Morgan by, representatives of Geon, and
that the other transactions contemplated by the Master Agreement and related
agreements have been consummated as described in the Master Agreement and
related agreements.
    
 
   
     The forecasts furnished to J.P. Morgan for the Contributed Businesses were
prepared by Geon. Geon does not publicly disclose its internal management
projections of the type provided to J.P. Morgan in connection with J.P. Morgan's
analysis of the Joint Venture Transactions, and such projections were not
prepared with a view toward public disclosure. These projections were based on
numerous variables and assumptions that are inherently uncertain and may be
beyond the control of management, including, without limitation, factors related
to general economic and competitive conditions and prevailing interest rates.
Accordingly, actual results could vary significantly from those set forth in
such projections.
    
 
     J.P. Morgan's opinion is based on economic, market, and other conditions as
in effect on, and information made available to J.P. Morgan as of, the date of
such opinion. Subsequent developments may affect J.P. Morgan's written opinion
dated December 22, 1998, and J.P. Morgan does not have any obligation to update,
revise, or reaffirm such opinion. J.P. Morgan expressed no opinion as to the
price at which Geon Common Stock will trade at any time in the future.
 
     In accordance with customary investment banking practice, J.P. Morgan
employed generally accepted valuation methods in reaching its opinion. The
following is a summary of the material financial analyses utilized by J.P.
Morgan in connection with providing its opinion:
 
     Public Transaction Multiples. Using publicly available information, J.P.
Morgan compared selected financial data of certain assets to be transferred from
OxyChem to Geon pursuant to the terms described in the Master Agreement and
related agreements with similar data for selected public transactions which J.P.
Morgan judged to be similar to the assets to be transferred to Geon. The assets
to be transferred to Geon pursuant to the terms of the Master Agreement and
related agreements are the assets associated with the Burlington and Pasadena
Subject Businesses (the "Burlington Assets" and the "Pasadena Pellet Assets,"
respectively) and OxyChem's Compounding Contributed Assets. The transactions
selected to be similar were Laporte's acquisition of Inspec Group in August
1998, Borden Chemical's acquisition of Melamine Chemicals in October 1997,
Ecolab's acquisition of Gibson Chemical in August 1997, Inspec Group's
acquisition of Shell Fine Chemicals in July 1996, Mallinckrodt's acquisition of
J.T. Baker in December 1994, and Vulcan Material's acquisition of Callaway
Chemicals in May 1994. These transactions were selected, among other reasons,
because their financial and operating characteristics, in aggregate, were
similar to the assets to be transferred to Geon. J.P. Morgan also noted that no
transaction it reviewed was identical to the assets to be transferred to Geon
and that, accordingly, an assessment of the results of the following analysis
necessarily involves complex considerations and judgments concerning differences
in financial and operating characteristics and other factors that would affect
the acquisition value of the companies to which both were compared. Among other
factors, J.P. Morgan indicated that the merger and acquisition transaction
environment varies over time because of macroeconomic factors such as interest
rate and equity market fluctuations and microeconomic factors such as industry
results, the business cycle, and growth expectations. J.P. Morgan reviewed each
target's multiple of firm value to last twelve months ("LTM") earnings before
interest and taxes ("EBIT") and firm value to LTM earnings before interest,
taxes depreciation, and amortization ("EBITDA"). The median multiple of firm
value to EBIT and firm value to EBITDA was 12.7x and 8.8x, respectively. J.P.
Morgan applied the range of transaction multiples of firm value to LTM EBIT of
between 11.0x and 12.0x, and of firm value to LTM EBITDA of between 7.5x and
8.5x. to LTM earnings, yielding an implied transaction value range of between
$65 million and $85 million for the Burlington Assets and the Pasadena Pellet
Assets.
 
                                       32
<PAGE>   44
 
     The implied values yielded by the public transaction multiples for the
Burlington Assets and the Pasadena Pellet Assets were deemed most appropriate by
J.P. Morgan to analyze the representative value received for assets to be
transferred in the aggregate analysis of the Contributed Consideration and
Received Consideration by Geon in the Joint Venture Transactions in the public
trading multiples valuation and the capital replacement cost valuation described
below. For the aggregate analysis of the Contributed Consideration and Received
Consideration by Geon in the Joint Venture Transactions in the discounted cash
flow valuation analysis, J.P. Morgan performed discounted cash flow analyses for
the Burlington Assets and the Pasadena Pellet Assets as described below, but
believed the implied values public transaction multiples to be most appropriate
in analyzing the value of these assets to be transferred to Geon.
 
     Public Trading Multiples. Using publicly available information, J.P. Morgan
compared selected financial data of Geon and OxyChem with similar data for
selected publicly traded companies engaged in businesses which J.P. Morgan
judged to be analogous to the assets of Geon and OxyChem that will be
contributed to the PVC Partnership. The companies selected to be analogous to
these assets were Dow Chemical, Eastman Chemical, Georgia Gulf, and Union
Carbide. These companies were selected, among other reasons, because their
business operations, in aggregate, are similar to those of the assets to be
contributed to the PVC Partnership by Geon and OxyChem. Given the cyclical
nature of the petrochemicals/vinyls industry, normalized multiples over the
cycle (1991 to 1997) for the above mentioned comparable companies were deemed
appropriate. J.P. Morgan used the average projected (12 month forward) firm
value to EBIT and firm value to EBITDA for its analysis. A range of 7.0x to 8.0x
firm value to EBIT and 5.5x to 6.5x firm value to EBITDA were appropriate for
the average of the periods analyzed. These multiples were applied to matrix of
normalized earnings provided to J.P. Morgan by Geon and OxyChem for the
respective assets to be contributed to the PVC Partnership, yielding an implied
value range of between $400 million and $500 million for Geon's PVC Contributed
Assets and between $1.15 billion and $1.25 billion for OxyChem's PVC Contributed
Assets. On a combined basis, public trading multiples yielded a value range of
between $1.55 billion and $1.725 billion for the PVC Partnership.
 
     Also using publicly available information, J.P. Morgan compared selected
financial data of Geon and OxyChem with similar data for selected publicly
traded companies engaged in businesses which J.P. Morgan judged to be analogous
to the assets of Geon and OxyChem that will be contributed to the Compounding
Partnership. The companies selected to be analogous to the assets were Ferro,
M.A. Hanna, and A. Schulman. These companies were selected, among other reasons,
because their business operations, in aggregate, are similar to those of the
assets to be contributed to the Compounding Partnership by Geon and OxyChem.
J.P. Morgan used current multiples of 1998 and 1999 firm value to EBIT and firm
value to EBITDA for its analysis. Multiples of 8.6x and 8.1x firm value to EBIT
for 1998 and 1999, respectively, and 6.5x and 6.2x firm value to EBITDA for 1998
and 1999, respectively, were believed to be appropriate for the periods
analyzed. These multiples were applied to estimated current earnings provided to
J.P. Morgan by Geon and OxyChem for their respective assets to be contributed to
the Compounding Partnership, yielding an implied stand-alone value range of
between $35 million and $45 million for Geon's Compounding Contributed Assets
and between $60 million and $70 million for OxyChem's Compounding Contributed
Assets. On a combined basis, public trading multiples yielded a stand-alone
valuation range of between $95 million and $115 million for the Compounding
Partnership.
 
     On an aggregate basis, and giving consideration to the approximate $185
million of debt to be contributed by Geon to the PVC Partnership, public trading
multiples yielded a value range of between $400 million and $510 million on an
equity basis for the Contributed Consideration. Also on an aggregate basis, and
giving consideration to the approximate net indebtedness of $487 million of the
PVC Partnership, the implied public transaction multiples value ranges for the
Burlington Assets and the Pasadena Pellet Assets, and the $110 million realized
by Geon through the retention of working capital and the distribution of cash
from the PVC Partnership, public trading multiples yielded a value range of
between $660 million and $740 million on an equity basis for the Received
Consideration.

     Capital Replacement Cost Analysis. In accordance with industry practice,
J.P. Morgan estimated the capital replacement cost of the assets to be
contributed by Geon and OxyChem to the PVC Partnership pursuant to the terms of
the Master Agreement and related agreements by using capital replacement cost
estimates for world scale greenfield capacity facilities as defined and
published by Chem Data Inc., an industry consulting firm located in Houston,
Texas. A world scale facility, as described by Chem Data Inc., is a reference to
its estimate of the annual rated capacity that would be required for a new
production facility to obtain sufficient scale economies by using modern
technologies to be among the top quartile of industry participants from a
processing cost perspective. The term "greenfield" is used to describe the
construction of a production facility that includes all operationally required
infrastructure (e.g. build from the ground up). This description is different
than constructing new capacity on an existing site that may already have
existing ancillary equipment installed to service other operations and only
requires incremental expansion of such ancillary equipment to service the
requirements of the newly constructed production facility.
 
     Based upon the industry estimates prepared by Chem Data Inc., J.P. Morgan
estimated the capital replacement cost value of the assets to be contributed to
the PVC Partnership by Geon and OxyChem by using a scale adjustment factor, also
provided by Chem Data Inc. and commonly used in the industry, to adjust the
capital replacement cost for world scale greenfield capacity cost estimates to
the actual estimated capacities of each asset to be contributed to the PVC
Partnership. A depreciation factor range of 0.6x to 0.7x for VCM and PVC resin
assets and 0.65x and 0.75x for chlor-alkali assets was deemed appropriate by
among other things, conversations with Geon and OxyChem managements regarding
the relative cost position of the assets and general industry fundamentals. The
results of the capital replacement cost analysis yielded an implied value range
of between $510 million and $620 million for Geon's PVC Contributed Assets and
between $1.08 billion and $1.25 billion for OxyChem's PVC Contributed Assets. On
a combined basis, the results of the capital replacement cost analysis yielded a
value range of between $1.59 billion and $1.87 billion for the PVC Partnership.
 
     Giving consideration to, among other things, the absence of applicable
capital replacement cost data for consideration included in the Contributed
Consideration and Received Consideration other than the PVC Contributed Assets,
J.P. Morgan relied upon implied public transaction multiples value ranges for
the Burlington Assets and the Pasadena Pellet Assets and implied public trading
multiples value ranges for the respective Compounding Contributed Assets in its
valuation assessment of aggregate Contributed Consideration and aggregate
Received Consideration using the capital replacement cost analysis methodology.
On an aggregate basis, and giving consideration to the approximate $185 million
of debt to be contributed by Geon to the PVC Partnership, the capital
replacement cost analysis yielded a value range of between $510 million and $630
million on an equity basis for the Contributed Consideration. Also on an
aggregate basis, and giving consideration to the approximate net indebtedness of
$487 million of the PVC Partnership, the implied public transaction multiples
value ranges for the Burlington Assets and the Pasadena Pellet Assets, and the
$110 million realized by Geon through the retention of working capital and the
distribution of cash from the PVC Partnership, the capital replacement costs
analysis yielded a value range of between $670 million and $780 million on an
equity basis for the Received Consideration.
 
   
     Discounted Cash Flow Analysis. J.P. Morgan conducted a discounted cash flow
analysis for the purpose of determining the firm value of all of the Contributed
Assets of Geon and OxyChem. J.P. Morgan calculated the unlevered free cash flows
that each of OxyChem's Contributed Assets and that each component of the
Contributed Consideration and Received Consideration are expected to generate
during fiscal years 1999 through 2006 based upon financial projections prepared
by Geon through the year ended 2006 and upon a series of projections prepared by
Geon for each of the Contributed Assets of both parties adjusted by J.P. Morgan
to reflect both more moderate and more aggressive growth in revenues and lower
and higher operating margins during each of the eight year projected periods.
J.P. Morgan also calculated a range of terminal asset values of each of the PVC
Contributed Assets at the end of the eight year periods ending 2006 by applying
a firm value to EBITDA multiple range of 5.5x to 6.5x to the average EBITDA for
the projected period 1999 through 2006 for the
    
 
                                       34
<PAGE>   46
 
   
PVC Contributed Assets and for the Resin Agreement. For the Compounding
Contributed Assets, the Burlington Assets and the Pasadena Pellet Assets, J.P.
Morgan calculated a range of terminal asset values at the end of the eight year
periods by applying a growth rate range of 2.5% to 3.5% for the terminal period
cash flows. For all Contributed Assets, the unlevered free cash flows and the
range of terminal asset values were then discounted to present values using a
range of discount rates from 9.0% to 10.0% which were chosen by J.P. Morgan
based upon analysis of the weighted average cost of capital of Geon and OxyChem.
Based on Geon projections for the PVC Contributed Assets as adjusted by J.P.
Morgan, the terminal period firm value to EBITDA range of 5.5x to 6.5x described
above, and a discount rate range of 9.0% to 10.0%, the discounted cash flow
analysis indicated a range of firm values of between $480 million and $570
million for Geon's PVC Contributed Assets and between $1.08 billion and $1.24
billion for OxyChem's PVC Contributed Assets. On a combined basis, discounted
cash flow analysis indicated a value range of between $1.56 billion and $1.81
billion for the PVC Partnership.
    
 
   
     Based upon Geon projections for the Compounding Contributed Assets as
adjusted by J.P. Morgan, a growth rate range of 2.5% to 3.5% for terminal period
cash flows, and a discount rate range of 9.0% to 10.0%, the discounted cash flow
analysis indicated a range of stand-alone firm values of between $45 million and
$55 million for Geon's Compounding Contributed Assets and between $60 million
and $75 million for OxyChem's Compounding Contributed Assets. On a combined
basis, the discounted cash flow analysis indicated a range of stand-alone firm
values of between $105 million and $130 million for the Compounding Partnership.
Based upon Geon projections for the Burlington Assets and the Pasadena Pellet
Assets to be transferred to Geon as adjusted by J.P. Morgan, a growth rate range
of 2.5% to 3.5% for terminal period cash flows, and a discount rate range of
9.0% to 10.0%, the discounted cash flow analysis indicated a range of
stand-alone firm values of between $55 million and $75 million for the
Burlington Assets and the Pasadena Pellet Assets.
    
 
     On an aggregate basis, and giving consideration to the approximate $185
million of debt to be contributed by Geon to the PVC Partnership, the discounted
cash flow analysis indicated a range of values of between $490 million and $590
million on an equity basis for the Contributed Consideration. Also on an
aggregate basis, and giving consideration to the approximate net indebtedness of
$487 million of the PVC Partnership, the implied public transaction multiples
value ranges for the Burlington Assets and the Pasadena Pellet Assets, and the
$110 million realized by Geon through the retention of working capital and the
distribution of cash from the PVC Partnership, the discounted cash flow analysis
indicated a range of values of between $670 million and $780 million on an
equity basis for the Received Consideration.
 
     Synergies.  Based upon detailed analysis provided to J.P. Morgan by Geon
and OxyChem relating to the anticipated annual synergies expected to be realized
by the PVC Partnership pursuant to the terms described in the Master Agreement
and related agreements, the PVC Partnership is expected to generate
approximately $80 million in annual synergies in the form of cost savings, from
among other things, the elimination of duplicate functions and revenue
enhancement. Based upon projections, J.P. Morgan judged to be most applicable, a
growth rate of 0% for terminal period cash flows, and a discount rate range of
9.0% to 10.0%, and giving consideration to the anticipated implementation
schedule of the synergies and the costs incurred in realizing the synergies, the
discounted cash flow analysis indicated a range of firm values of between $400
million and $470 million for the PVC Partnership synergies. Anticipated
synergies and the value thereof, described in this paragraph, are in addition to
the value ranges indicated for the Contributed Consideration and the Received
Consideration described in the preceding paragraphs above and are therefore not
incorporated into these analyses. It is anticipated by Geon and OxyChem that
each party will share, pro rata to its ownership interest in the PVC
Partnership, any value of the synergies realized by the PVC Partnership.
 
     The summary set forth above does not purport to be a complete description
of the analyses or data presented by J.P. Morgan. The preparation of a fairness
opinion is a complex process and is not necessarily susceptible to partial
analysis or summary description. J.P. Morgan believes that the summary set forth
above and its analyses must be considered as a whole and that selecting portions
thereof, without considering all if its analyses, could create an incomplete
view of the processes
                                       35
<PAGE>   47
 
underlying its analyses and opinion. J.P. Morgan based its analysis on
assumptions that it deemed reasonable, including assumptions concerning general
business and economic conditions and industry-specific factors. The other
principal assumptions upon which J.P. Morgan based its analyses are set forth
above under the description of each such analysis. J.P. MORGAN'S ANALYSES ARE
NOT NECESSARILY INDICATIVE OF ACTUAL VALUES OR ACTUAL FUTURE RESULTS THAT MIGHT
BE ACHIEVED, WHICH VALUES MAY BE HIGHER OR LOWER THAN THOSE INDICATED. MOREOVER,
J.P. MORGAN'S ANALYSES ARE NOT AND DO NOT PURPORT TO BE APPRAISALS OR OTHERWISE
REFLECTIVE OF THE PRICES AT WHICH BUSINESSES COULD ACTUALLY BE BOUGHT OR SOLD.
 
     As a part of its investment banking business, J.P. Morgan and its
affiliates are continually engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, investments for passive
and control purposes, negotiated underwritings, secondary distributions of
listed and unlisted securities, private placements, and valuations for estate,
corporate, and other purposes. J.P. Morgan was selected to deliver an opinion to
the Geon Board with respect to the Joint Venture Transactions on the basis of
such experience and on its familiarity with Geon.
 
     For the delivery of its opinion, Geon has agreed to pay J.P. Morgan a fee
of $500,000. In addition, Geon has agreed to reimburse J.P. Morgan for its
expenses incurred in connection with its services, including fees and
disbursements of counsel, and will indemnify J.P. Morgan against certain
liabilities. As compensation for providing advisory, lending, asset management
services, and other investment banking services, Geon paid J.P. Morgan
approximately $400,000 in each of 1997 and 1998.
 
     J.P. Morgan and its affiliates maintain banking and other business
relationships with Geon and OPC and their respective affiliates, for which it
receives customary fees. In the ordinary course of their businesses, affiliates
of J.P. Morgan may actively trade the debt or equity securities of Geon or OPC
for their own accounts or for the accounts of customers and, accordingly, they
may at any time hold long or short positions in such securities.
 
     J.P. Morgan has consented to the use of its opinion letter dated December
22, 1998, attached as Annex A to this Proxy Statement, and the references to
such opinion in this document. In giving such consent, J.P. Morgan did not admit
that it came within the category of persons whose consent is required under
Section 7 of the Securities Act of 1933, as amended, or the rules and
regulations of the Securities and Exchange Commission thereunder, nor did J.P.
Morgan admit that it is an expert with respect to any part of this Proxy
Statement within the meaning of the term "experts" as used in the Securities Act
or the rules and regulations of the Commission thereunder.
 
CERTAIN CONSEQUENCES OF THE JOINT VENTURE TRANSACTIONS
 
     After the closing of the Joint Venture Transactions, Geon will continue to
exist in accordance with the current provisions of its Certificate of
Incorporation and Bylaws. The businesses retained by Geon following the Joint
Venture Transactions will include Geon's vinyl compounding (other than
powder/dry blend compounding), specialty resin, and plastisol formulation
businesses. With respect to each of these retained businesses, Geon believes it
is the North American sales leader with strong technology. These retained
businesses, together with Geon's interest in each of the Partnerships, will form
the platform from which Geon will seek to become an international performance
polymer and service company with the potential for greater earnings growth and
reduced commodity earnings volatility. Geon will also retain its 50% equity
interest in the Sunbelt Chlor Alkali Partnership, and its 37.4% equity interest
in Australian Vinyl Corporation. Including the consolidated results of the
Compounding Partnership, these businesses are expected to have sales of
approximately $1.2 billion in 1999.
 
     Following the Joint Venture Transactions, Geon will cease operating the PVC
suspension and mass resin business it contributed to the PVC Partnership and
will participate in the PVC Partnership only through its wholly-owned subsidiary
which owns a 24% interest in the PVC Partnership. Initially, Geon expects that
the PVC and VCM product consumption of Geon's retained businesses will
approximate 24% of the expected product output of the PVC Partnership. Geon
expects the balance between its equity interest and expected product consumption
to result in the strength of backward integration.
                                       36
<PAGE>   48
 
Geon's purchases of product from the PVC Partnership, however, will be based
upon the needs of Geon's retained businesses and not on its equity interest in
the PVC Partnership.
 
     In addition, as a result of the Joint Venture Transactions, Geon will no
longer own the powder compounding assets that it contributed to the Compounding
Partnership. However, through its wholly-owned subsidiaries who are partners in
the Compounding Partnership, Geon will manage indirectly the Compounding
Partnership.
 
     After the closing, a Partnership Governance Committee will govern the PVC
Partnership. Each of Geon and OxyChem will be entitled to elect three of the six
members of the PVC Partnership Governance Committee. In general, the approval of
two or more representatives acting for OxyChem will be necessary and sufficient
for the PVC Partnership Governance Committee to take any action. However, the
PVC Partnership Governance Committee may not take certain actions unless such
actions are approved by two or more representatives acting for Geon. See "The
PVC Partnership Agreement -- Governance" and " -- Unanimous Voting
Requirements."
 
     A similar Partnership Governance Committee will govern the Compounding
Partnership. Each of Geon and OxyChem will be entitled to elect two of the four
members of the Compounding Partnership Governance Committee. In general, the
approval of one the representatives acting for Geon will be necessary and
sufficient for the Compounding Partnership Governance Committee to take any
action. However, the Compounding Partnership Governance Committee may not take
certain actions unless such actions are approved by at least one representative
acting for OxyChem. See "The Compounding Partnership Agreement -- Governance"
and " -- Unanimous Voting Requirements."
 
     After the closing, holders of Geon Common Stock will continue to have their
voting rights with respect to their shares. However, stockholders will not have
the right to directly vote in favor of, or against, the representatives chosen
by Geon to serve on the Partnership Governance Committees. Geon's Chief
Executive Officer will appoint such representatives. The Partnership Governance
Committees will have the ability, subject to the limitations related to matters
requiring approval of both Geon and OxyChem representatives, to permit the
transfer of partnership interests, the admission of new members, and the
issuance of additional partnership interests, thereby potentially diluting
Geon's interests in each Partnership without the approval of Geon's
stockholders.
 
     Geon will source most of its PVC resin requirements and all of its VCM
requirements from the PVC Partnership through long-term supply arrangements
extending at least 15 years with options to extend for an additional 10 years.
In addition, Geon will be party to certain administrative support contracts with
the Partnerships whereby OxyChem will primarily support the PVC Partnership and
Geon will primarily support the Compounding Partnership, as well as certain
interim transition services agreements. See "Certain Related Party
Transactions."
 
ACCOUNTING TREATMENT
 
     Effective as of the closing, Geon will account for its limited partnership
interest in the PVC Partnership on an equity basis and will account for its
general partnership interest and limited partnership interest in the Compounding
Partnership by recording the net assets contributed by OxyChem at their fair
value and consolidating the results of the Compounding Partnership adjusted for
OxyChem's minority interest. This accounting treatment is reflected in the pro
forma financial statements of Geon that are included in this Proxy Statement.
 
FEDERAL INCOME TAX CONSEQUENCES OF THE JOINT VENTURE TRANSACTIONS
 
     The Joint Venture Transactions will have no federal income tax consequences
for the stockholders of Geon. Geon is not expected to recognize gain or loss for
federal income tax purposes as a result of the Joint Venture Transactions. Geon
intends that the contribution of assets (subject to liabilities) by Geon to the
Partnerships will qualify as a tax-free contribution under Section 721 of the
Internal Revenue Code of 1986, as amended (the "Code"), in which Geon will not
recognize gain or loss. Geon
 
                                       37
<PAGE>   49
 
and OxyChem have agreed that each Partnership will file its federal income tax
return on the basis that such contribution of assets is tax-free under Section
721 of the Code, and Geon and OxyChem have each agreed to file its federal
income tax return on the same basis and to maintain such position consistently
at all times thereafter. Geon has neither solicited nor received an opinion of
tax counsel with regard to the applicability of Section 721 of the Code in
connection with the Joint Venture Transactions.
 
NO APPRAISAL RIGHTS
 
     Delaware law governs stockholders' rights in connection with the Joint
Venture Transactions. Under the applicable provisions of the DGCL, holders of
Geon Common Stock will not have any rights in connection with the Joint Venture
Transactions to dissent and seek appraisal of their shares of common stock.
 
CLOSING DATE
 
   
     The closing is expected to take place promptly following the satisfaction
or waiver of all of the conditions set forth in the Master Agreement, including,
without limitation, receipt of the requisite affirmative votes of the
stockholders of Geon. See "The Master Transaction Agreement -- Closing Date."
Geon currently anticipates that the asset transfers will be consummated during
the second quarter of 1999, and that the Partnerships will be fully operational
by that date.
    
 
REGULATORY APPROVALS
 
     Geon does not believe that any material federal or state regulatory
approvals will be necessary in connection with the Joint Venture Transactions.
The applicable waiting periods under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, with regard to the Burlington Subject Business, and
the Competition Act (Canada) have expired. In addition, on February 2, 1999, the
Federal Trade Commission informed Geon that it had terminated its investigation
related to the Joint Venture Transactions with a recommendation for no further
action.
 
                                  THE PARTIES
 
GEON
 
   
     Generally. Geon, together with its subsidiaries, is the world's largest
manufacturer and marketer of PVC compounds, the largest North American
manufacturer of PVC dispersion resins, and a leading North American producer of
PVC resins. PVC is the world's second most widely used plastic. It is an
attractive alternative to traditional materials such as glass, metal, and wood
and other plastic materials because of its versatility, durability, and cost
competitiveness. PVC's largest applications are associated with infrastructure
development, building products, and consumer durable goods. Geon also produces
VCM, an intermediate precursor to PVC. Geon's operations are located primarily
in the United States and Canada in two business segments. The "Performance
Polymers and Services" segment includes PVC compounds, including two joint
ventures, specialty resins, plastisol formulators, and analytical testing
services. The "Resin and Intermediates" segment includes suspension and mass
resins, VCM, Geon's 50% equity holding in the SunBelt chlor-alkali joint
venture, and Geon's 37.4% interest in Australian Vinyls Corporation (AVC), an
Australian PVC operation. During 1998, Geon also acquired three plastisol
formulator businesses: Plastomeric, Inc., the Wilflex Division of Flexible
Products Company, and Adchem, Inc. These acquisitions added approximately 300
employees at 5 locations. As of December 31, 1998, Geon's North American
nameplate commodity suspension/mass PVC resin capacity was approximately 2.6
billion pounds, or approximately 18% of total U.S. and Canadian PVC capacity.
    
 
                                       38

     On June 24, 1998, the last trading day before the Geon Board announced its
signing of the Letter of Intent relating to the Joint Venture Transactions, the
high and low sales prices for Geon Common Stock on the New York Stock Exchange
were $19.688 and $19.250, respectively.
 
   
     Products. Geon's Performance Polymers & Services products include PVC
compounds, specialty resins, plastisols, and plastisol formulations. In
addition, Geon offers its analytical, testing, and problem-solving capabilities
to customers and suppliers through its subsidiary, Polymer Diagnostics Inc. With
the acquisitions of the formulator businesses in 1998, Geon added urethane
powder coatings, vinyl plastisol inks used in ink transfers, and polymer
additives such as blowing agents and pigments to its products. Compounds are
made by combining vinyl resin with additives. Depending upon the additives used,
the compound can be either rigid and impact-resistant or soft and flexible.
Compounds are fabricated by customers of Geon by extrusion, calendaring,
injection-molding, or blow-molding. Flexible compounds are used for wire and
cable insulation, automotive interior, and exterior trim, packaging, and medical
devices. Rigid extrusion PVC compounds are commonly used in window frames,
vertical blinds, and construction applications. Geon also manufactures
plastisizers which give flexibility to PVC. Injection-molding PVC compounds are
used in specialty parts like business machine components, appliance parts, and
bottles. Geon's development of compounds that can be injection-molded into
thin-walled complex parts or that have other unique characteristics has opened
new applications and markets for PVC. Specialty resins are much finer in
particle size than suspension resins and when compounded with plasticizers they
take on soft, flexible characteristics. They are used primarily in wire and
metal coatings, vinyl flooring, vinyl wall coverings, and automotive interiors,
as well as in consumer products such as toys. Geon supports its Performance
Polymers & Services products by providing service to customers through enhanced
customer support. Geon's sales force works with engineering and marketing
experts of original equipment manufacturers in addition to purchasing agents to
create new uses for PVC products and to replace more costly plastics and other
traditional materials such as wood, glass, or aluminum through the development
of cost-effective solutions that meet specific customer needs. In addition, Geon
uses a combination of material science, computer-aided design, and prototype
part production capabilities to assist customers in the development and
application of new uses for higher-performance PVC compounds.
    
 
   
     Geon's Resin & Intermediates products include PVC suspension and mass
resins and VCM. In addition, Geon produces chlorine through a joint venture
arrangement. PVC suspension and mass resins, named for the different processes
used to produce them, are powders that cannot be used without the addition of
ingredients to form a vinyl compound. Suspension/mass resins can be further
categorized as general purpose and special purpose resins. General purpose
resins comprise the largest segment of resins by volume and are typically used
in rigid applications such as pipe and exterior siding. Special purpose resins
are a broad category of resins possessing unique characteristics, such as color
and clarity, and are used in a wide variety of applications such as film,
medical, and automotive products. Geon's PVC resin production supplies Geon's
compounding operations. In addition, Geon sells PVC resin to third party trade
customers. Similarly, VCM is used primarily internally for the production of PVC
resin. Geon supplies approximately one-third of its chlorine requirements
through a joint venture arrangement with Olin Corporation.
    
 
   
     Competition. Geon competes with major U.S. chemical manufacturers and
diversified companies, some of which have greater financial resources than Geon.
Competition in the industry is based upon factors, the importance of which vary
depending on the specific characteristics of the product and the applicable
market, ranging from price and availability to product performance and customer
and technical support. With respect to PVC resins, Geon competes primarily with
seven major North American PVC producers: Borden Chemicals and Plastics Limited
Partnership; CONDEA Vista Chemical Company (a subsidiary of RWE-DEA Hamburg,
Germany); Formosa Plastics Corporation U.S.A. (a subsidiary of Formosa Plastic
Group, Taipei, Taiwan); Georgia Gulf Corporation; Shintech, Inc. (a subsidiary
of Shin Etsu Chemical Co., Ltd., Tokyo, Japan); The Westlake Group; and OxyChem.
The key competitive factors are price, product availability, and performance. In
1998, the eight largest resin producers (one of which is Geon) accounted for
approximately 90% of the total estimated resin capacity. None of the
    
 
                                       39
<PAGE>   51
 
   
producers had more than 20% of total resin capacity. With respect to PVC
compounds, Geon competes with certain of the foregoing entities along with many
independent custom compounders.
    
 
   
     Because there is no single PVC compound market, the manner in which Geon
competes varies from market to market, although in each market Geon competes
primarily on the basis of product consistency and customer service in addition
to price. In certain PVC compound markets, such as pipe fittings, wire and
cable, and bottles, Geon competes with other PVC resin manufacturers. In the
markets for higher performance PVC compounds, such as extrusion and injection
molding compounds for business equipment, appliances, telecommunications, and
construction, Geon competes less with traditional PVC manufacturers and more
with other non-PVC plastic manufacturers, such as General Electric Company,
Bayer AG, and The Dow Chemical Company. Manufacturing margins and prices in
these markets tend to be higher and more stable than PVC resin and other
compound markets, although such areas have higher support costs comprised of
sales, marketing, technical service, customer support, and research and
development. In the other PVC compound markets (rigid extrusion compounds for
custom profiles, window lineals, and vertical blinds), Geon competes with other
PVC manufacturers and custom compounders.
    
 
   
     Raw Materials. Geon produces the majority of the VCM it requires for the
manufacture of PVC at its plant in LaPorte, Texas. In April 1996, Geon expanded
the capacity of the LaPorte facility by 800 million pounds, bringing its
capacity to 2.4 billion pounds. In addition, Geon has a long-term Canadian VCM
supply contract providing substantially all VCM requirements for Geon's Canadian
PVC resin production located in Fort Saskatchewan, Alberta. The Canadian supply
contract remains effective through 2000.
    
 
   
     The two principal raw materials used by Geon to manufacture VCM are
ethylene and chlorine. The majority of Geon's ethylene requirements are provided
under three long-term supply agreements with the largest having an initial term
through December 31, 2005. The other significant long-term supply agreements
expire at the end of 2003 and 2005. Geon has over 95% of its anticipated
ethylene requirements under contract for 1999.
    
 
   
     Geon sources its chlorine requirements three ways: (1) participation in a
chlor-alkali joint venture; (2) agreement with Bayer Corporation for hydrogen
chloride; and (3) third party purchases.
    
 
   
     Geon has a 50% participation in a chlor-alkali plant under a joint venture
agreement with Olin Corporation. The plant, which began operations in the fourth
quarter of 1997, has a capacity of 250,000 tons. A future plant expansion to a
capacity of 400,000 tons can be accommodated.
    
 
   
     Geon has an agreement with Bayer Corporation under which Bayer and Geon
operate a pipeline to transport by-product anhydrous chloride from its plant to
Geon's nearby LaPorte, Texas, plant. This anhydrous chloride is converted to
chlorine for use in the VCM production process. This pipeline became fully
operational in October, 1998, and provides for delivery of anhydrous chloride
sufficient to provide 250,000 tons of chlorine beginning in the second half of
1999.
    
 
   
     The remainder of Geon's chlorine requirements are purchased from third
parties through long-term supply agreements (other than those discussed above)
and on the spot-market. Geon's primary long-term chlorine supply agreements are
with three different domestic suppliers which expire through 2005. These supply
agreements generally contain volume commitments and various pricing mechanisms
which Management believes provide a cost-effective sourcing of chlorine.
    
 
   
     Historically, chlorine and ethylene have been produced in the United States
at a lower cost than elsewhere in the world. This cost advantage has resulted in
U.S. producers of PVC having lower raw materials costs than their counterparts
in many other parts of the world. In addition to the raw materials for VCM, Geon
purchases a variety of additives to manufacture its compound products. These
materials generally have adequate alternative sources of supply and are not
purchased under multi-year contracts.
    
 
                                       40
<PAGE>   52
 
   
     In conjunction with the Joint Venture Transactions, Geon will enter into a
resin and VCM supply agreement with the PVC partnership under which it will
purchase a substantial portion of its PVC resin and VCM requirements. The
agreements will have an initial term of 15 years with renewal options.
    
 
   
     Research and Development. Geon has developed substantial research and
development capability. Geon's efforts are devoted to (i) providing support to
its manufacturing plants for cost reduction, productivity, and quality
improvement programs, (ii) providing quality technical services to assure the
continued success of its products for its customers' applications, (iii)
providing technology for improvements to its products, processes, and
applications, and (iv) developing new products to satisfy defined market needs.
Geon operates a research and development center in Avon Lake, Ohio. The
laboratory is equipped with modern analytical, synthesis, polymer
characterization, and testing equipment and pilot plants and polymer compounding
operations which simulate the production facilities for rapid translation of new
technology into new products.
    
 
   
     Expenditures for Geon sponsored product research and product development in
1998, 1997, 1996, and 1995 were $15.0 million, $17.1 million, $17.5 million, and
$18.0 million, respectively. Expenditures in 1999 are projected to remain at
approximately the same level as in 1998.
    
 
   
     Employees. As of December 31, 1998, Geon had approximately 2400 full-time
employees of whom approximately 180 employees are covered by collective
bargaining agreements which expire in July 2000, November 2000, and July 2001.
The bargaining unit employees are employed at Geon's facility in Kentucky and
the acquired Synergistics facilities located in Canada. Geon considers its
employee relations to be good.
    
 
   
     Environmental, Health and Safety. Geon is subject to various federal,
state, and local environmental laws and regulations concerning emissions to the
air, discharges to waterways, the release of materials into the environment, the
generation, handling, storage, transportation, treatment and disposal of waste
materials or otherwise relating to the protection of the environment. Geon
endeavors to ensure the safe and lawful operation of its facilities in
manufacturing and distribution of products and believes it is in compliance in
all material respects with applicable laws and regulations.
    
 
   
     Geon maintains a disciplined environmental and occupational safety and
health compliance program and conducts internal and external regulatory audits
at its plants in order to identify and categorize potential environmental
exposures and to ensure compliance with applicable environmental, health, and
safety laws and regulations. This is an effort which has required and may
continue to require process or operational modifications and the installation of
pollution control devices and cleanups.
    
 
   
     Geon's capital expenditures related to the limiting and monitoring of
hazardous and non-hazardous wastes totaled $4 million, $4 million, $3 million,
and $7 million in 1998, 1997, 1996, and 1995, respectively. In addition, Geon
estimates capital expenditures for future environmental improvement programs to
approximate $3 million to $5 million in 1999. The projected future capital
expenditures are associated with a wide variety of environmental projects such
as compliance with anticipated new regulations, achievement of internal company
programs and improved operating efficiencies, and expenditures to remediate the
acquired facilities to the historical environmental operating practices of Geon.
The primary areas for future environmental capital expenditures can be broadly
categorized as solid waste, air quality, waste water, and ground water
improvements. Expenditures for remediating various sites were $5.3 million, $5.0
million, $6.1 million, and $3.0 million in 1998, 1997, 1996, and 1995,
respectively. 1999 expenditures for remediation of these sites are projected to
be $5 million to $7 million.
    
 
   
     Geon has been notified by the U.S. Environmental Protection Agency, a state
environmental agency, or a private party that it may be a potentially
responsible party ("PRP") in connection with seven active and inactive non-Geon
owned sites. While government agencies frequently claim PRPs are jointly and
severally liable at these sites, in Geon's experience, interim and final
allocation of liability costs are generally made based on the relative
contribution of waste. Geon believes that it has potential continuing liability
with respect to only four such sites. In addition, Geon initiates corrective and
preven-
    
 
                                       41
<PAGE>   53
 
   
tive environmental projects of its own to ensure safe and lawful activities at
its operations. Geon believes that compliance with current governmental
regulations at all levels will not have a material adverse effect on its
financial condition. Based on estimates prepared by Geon's environmental
engineers and consultants, at December 31, 1998 and December 31, 1997, Geon had
accruals totaling $45.9 million and $51.0 million, respectively, to cover
probable future environmental expenditures related to previous contaminated
sites. The accrual represents Geon's best estimate for the remaining remediation
costs based upon information and technology currently available. Depending upon
the results of future testing and the ultimate remediation alternatives
undertaken at these sites, it is possible that the ultimate costs to be incurred
could be more than recorded at December 31, 1998 by as much as $14 million.
Geon's estimate of the liability may be revised as new regulations, technologies
or additional information is obtained.
    
 
   
     Of the $45.9 million accrued at December 31, 1998, for future environmental
expenditures, $17.3 million (and $18.2 million of the $51.0 million accrued at
December 31, 1997) is attributable to future remediation expenditures at the
Calvert City, Kentucky, site and less than $.5 million is attributable to
off-site environmental remediation liabilities, including the four sites
mentioned above. The remaining amount is primarily attributable to other
environmental remediation projects at nine other Geon-owned facilities. At
Calvert City, consent orders have been signed with both the U.S. Environmental
Protection Agency and the Commonwealth of Kentucky Department of Environmental
Protection which provide for a site-wide remediation program primarily to remove
ethylene dichloride ("EDC") from groundwater, the cost of which has been
accrued. Environmental expense incurred was $2.4 million in each of the years
ended December 31, 1998 and 1997, $4.2 million for the year ended December 31,
1996, and $1.2 million for the year ended December 31, 1995.
    
 
   
     Geon participates in the EPA Compliance Audit Program ("CAP") under Section
8(e) of the Toxic Substances Control Act. That section requires reporting of
information indicating a substantial risk of injury to health or the environment
from a chemical substance or mixture. Under the CAP, Geon conducts an audit of
its files and reports any information that should have been reported previously.
The total potential maximum liability of Geon and its subsidiaries under the CAP
is $1 million. The first part of the CAP required reporting of substantial risk
information concerning health effects. The remaining part of the CAP involves
substantial risk information concerning the environment. Geon will perform its
obligations under this portion of the CAP after the EPA issues guidance
concerning the kinds of environmental information that it believes are
reportable. Geon does not believe that its portion of any civil penalties
arising from this portion of the CAP will exceed $.2 million.
    
 
   
     The risk of additional costs and liabilities is inherent in certain plant
operations and certain products produced at Geon's plants, as is the case with
other companies involved in the PVC industry. There can be no assurance that
additional costs and liabilities will not be incurred by Geon in the future. It
is also possible that other developments, such as increasingly strict
environmental, safety and health laws, regulations and enforcement policies
thereunder and claims for damages to property or persons resulting from plant
emissions or products, could result in additional costs and liabilities to Geon.
    
 
   
     A number of foreign countries and domestic local communities have enacted,
or have under consideration, laws and regulations relating to the use and
disposal of plastic materials. Widespread adoption of such laws and regulations,
or public perception, may have an adverse impact on plastic materials. Although
many of Geon's major markets are in durable, longer-life applications which
could reduce the impact of any such environmental regulation, there is no
assurance that possible future legislation or regulation would not have an
adverse effect on Geon's business.
    
 
   
     In previous years there have been efforts by environmental groups to ban
chlorine -- one of Geon's key raw materials. Proposed legislation to ban
chlorine has garnered little support in Congress. Research does not support
categorizing all uses of chlorine as harmful to the environment. Although Geon
believes that PVC is not harmful to the consumer or the environment due to the
stability of its chemical structure, PVC could not be produced if chlorine and
chlorine-based products were prohibited. Another issue being addressed is the
presence of dioxins in the environment. Dioxins are produced by many
    
 
                                       42
<PAGE>   54
 
   
types of combustion and the EPA has cited municipal, medical, and industrial
incinerators as major sources of dioxin. Data generated to date by the American
Society of Mechanical Engineers and The Vinyl Institute indicate that vinyl and
vinyl production processes are at most minor contributors to overall dioxin
emissions.
    
 
   
     Geon does not believe that there are any new laws which will have a
material impact on the industry or Geon's capital expenditures, cash flow or
liquidity.
    
 
   
     Geon conducts a comprehensive occupational safety and health program.
Industry data shows that Geon's safety record is among the best in the chemical
industry.
    
 
   
     Consolidation of Compounding Operations. On November 18, 1998, Geon
announced the consolidation of its compounding operations with the closing of
two manufacturing plants and the partial closing of two additional plant sites.
The affected facilities, located in Canada and the United States, are part of
the former Synergistics Industries Ltd. operations that Geon acquired in the
fourth quarter of 1997.
    
 
   
     The consolidation will include the relocation of the production of certain
of Geon's product lines to other Geon facilities with existing available
capacity. As a result of the consolidation, Geon will write-off and dispose of
certain facilities, equipment, and certain other assets, the cost of which is
expected to approximate $22 million. In addition, Geon expects to incur employee
separation costs related to approximately 250 employees employed at the affected
plant sites. Geon expects to record $14.6 million of these charges in the fourth
quarter of 1998 and additional costs of $7.5 million in the first quarter of
1999. These charges include approximately $9 million of non-cash asset
write-offs. Approximately $4 million of these charges relate to the closing of
Geon's Conroe, Texas, powder compounding facility which will be closed after the
completion of the Joint Venture Transactions and production is transferred to
the Compounding Partnership and other plants.
    
 
     Geon expects to have the consolidation, announced on November 18, 1998,
completed by mid-1999 and anticipates that the consolidation will improve
productivity and customer service and produce estimated savings of $6 million in
1999 and $14 million annually thereafter. The consolidation is part of Geon's
overall strategic plans that include the Joint Venture Transactions.
 
   
     On completion of the Joint Venture Transactions, Geon will have completed
the first step in its vision to be a leading international performance polymer
and services company. Geon is currently the largest vinyl compounder in the
world and the leading North American producer of specialty dispersion resins.
Geon has become skilled in operating businesses of this type in which
technology, services, and cost management are paramount. Geon's businesses
combined with Geon's operating and technology know-how provide a core platform
for Geon's future growth in related products and services both in North America
and international markets.

          - a leading manufacturer and marketer of chlorine and caustic soda in
            the United States;
 
          - together with OxyMar (OxyChem's joint venture with Marubeni
            Corporation), a leading producer of VCM in the United States; and
 
          - a leading manufacturer and marketer of PVC resins in North America.
 
     A substantial portion of OxyChem's products are principally commodity in
nature. They are equivalent to products manufactured by others that are
generally available in the marketplace and are produced and sold in large
volumes, primarily to industrial customers for use as raw materials. OxyChem
sells its products to third parties and, in addition, uses the products its
produces internally and further processes them into other chemical products.
Nearly all raw materials utilized in OxyChem's operations that are not produced
by OxyChem or that are acquired from affiliates are readily available from a
variety of sources. Most of OxyChem's key raw materials purchases are made
through short-and long-term contracts.
 
     Among other products, OxyChem produces the following chemical products:

     Geon and OxyChem will each contribute to the Partnerships certain
businesses and related assets which are describe below.
 
PVC PARTNERSHIP
 
     Geon and OxyChem will each contribute to the PVC Partnership its PVC
Contributed Business consisting of its PVC suspension and mass resin and VCM
manufacturing and supply businesses and certain assets relating to such
businesses. PVC suspension and mass resins, named for the different processes
used to produce them, are powders that cannot be used commercially without the
addition of ingredients to form a vinyl compound. VCM is a necessary ingredient
in the production of PVC resins.
 
     Geon. Geon will contribute the following facilities to the PVC Partnership:
(i) PVC manufacturing facilities located in Deer Park, Texas, and Fort
Saskatchewan, Alberta, Canada, (ii) a VCM manufacturing facility located in

<PAGE>   57
 
suspension and mass resins, certain manufacturing facilities located at
Pedricktown, New Jersey, and certain facilities and site utility support assets
located at Louisville, Kentucky, and Niagara Falls, Ontario, Canada. These
plants had a nominal base capacity in 1998 of 2.4 billion pounds of PVC and 2.4
billion pounds of VCM. Geon will also contribute to the PVC Partnership certain
transportation equipment, storage facilities, and rights of way used at the
foregoing facilities and its reactor coatings, catalyst sales, and PVC
suspension and mass resin and VCM licensing businesses. Geon will also
contribute all of the outstanding stock of its LaPorte Chemicals subsidiary
which is the holder of a special purpose subsidiary formed to facilitate the
transfer of the Canadian assets described above to the PVC Partnership.
 
     In addition, Geon will contribute certain significant contractual rights to
the PVC Partnership. Geon will contribute its rights under long-term ethylene
and chlorine purchase contracts. Geon will provide to the PVC Partnership the
benefit of the rates in a supply agreement for chlorine produced by Sunbelt
Chlor Alkali Partnership, Geon's joint venture with Olin Corporation. Geon will
also contribute its agreements with Dow Chemical and Bayer Corporation pursuant
to which these companies supply anhydrous hydrogen chloride from their plants in
the Houston area to Geon's VCM plant in LaPorte, Texas.
 
     OxyChem. OxyChem will contribute to the PVC Partnership its (i) PVC
manufacturing facilities located in Pasadena, Texas, and its VCM manufacturing
facilities located in Deer Park, Texas, and (ii) 50% interest in OxyMar, a joint
venture with Marubeni Corporation which operates a VCM plant in Ingleside,
Texas. These plants, including 50% of the capacity of OxyMar, had a nominal base
capacity in 1998 of 1.8 billion pounds of PVC and 2.3 billion pounds of VCM. In
addition, OxyChem will contribute to the PVC Partnership its chlor-alkali assets
and co-generation power plants at its Houston, Texas, Chlor-Alkali Complex.
 
     OxyChem will also contribute to the PVC Partnership its contractual rights
under certain long-term ethylene purchase contracts, including, without
limitation, OxyChem's long-term supply agreement with Equistar Chemicals, LP,
its joint venture affiliate. OxyChem will also contribute rights to certain
transportation equipment, storage facilities, and rights of way used at the
foregoing facilities.
 
BUSINESS OF THE PVC PARTNERSHIP FOLLOWING THE JOINT VENTURE TRANSACTIONS
 
     Generally. Using the assets contributed to it by Geon and OxyChem, the PVC
Partnership will produce and purchase or otherwise acquire, use, distribute,
market, and exchange throughout the world suspension and mass PVC resin
products, VCM (to the extent permitted under applicable agreements concerning
VCM produced by OxyMar), caustic soda, and chlorine and carry on related
development, licensing, and other ancillary activities, including incidental use
or sale of PVC dry blend/powder compound to support the PVC Partnership's
customers as mutually agreed by the partners.
 
     The PVC Partnership will also distribute and market any excess caustic soda
and chlorine not consumed in the primary business, but only through OxyChem and
in accordance with agreements between the PVC Partnership and OxyChem.
 
     The business of the PVC Partnership will not include producing, purchasing,
or otherwise acquiring, using, distributing, marketing, and exchanging
dispersion, blending, specialty suspension, and copolymer resins.
 
     The PVC Partnership will conduct its operations at the facilities
contributed to it by Geon and OxyChem. The PVC Partnership is expected to have
manufacturing capacity totaling 4.2 billion pounds of PVC and 4.8 billion pounds
of VCM and chlor-alkali capacity of 900,000 electrochemical units (equivalent to
900,000 tons of chlorine and 990,000 tons of caustic soda).
 
     Sales and Marketing. The PVC Partnership will sell its PVC resins to third
parties who produce their own compounds for use primarily in larger volume
construction applications, such as pipe and pipe fittings, vinyl house siding,
flooring, wall coverings, wire coatings, and window components. In addition,
 
                                       46
<PAGE>   58
 
the PVC Partnership will enter into long-term supply arrangements to supply PVC
resins to Geon and the Compounding Partnership. The PVC Partnership is expected
to use the VCM it produces primarily for the production of its PVC resin.
However, the PVC Partnership will enter into long-term supply arrangements to
supply VCM to Geon and OxyChem, as well as supplying VCM to third parties. See
"Certain Related Party Transactions."
 
     OxyChem will market all caustic soda and chlorine from the PVC Partnership
not required or used in the operation of the PVC Partnership. For such
marketing, OxyChem will receive a fixed fee corresponding to historical costs
for the first two years, and thereafter a fee equal to OxyChem's full cost. The
PVC Partnership will receive all revenues, based on the average external sales
price for such commodities throughout OxyChem's entire system, for the sales of
such caustic soda and chlorine, less OxyChem's fee. As part of such
arrangements, the PVC Partnership will manufacture and sell to OxyChem at full
cost its chlorowax and sodium methylate (e.g., chlorinated paraffins) products.
 
     Research and Development. The PVC Partnership will have substantial
research and development capabilities. The PVC Partnership's efforts will be
devoted to: (i) providing support to its manufacturing plants for cost
reduction, productivity, and quality improvement programs, (ii) providing
quality technical services to assure the continued success of its products for
its customers' applications, (iii) providing technology for improvements to its
products, processes, and applications, (iv) developing new products to satisfy
defined market needs, (v) supporting development of strong licensing offerings,
and (vi) continued development of reactor coatings and catalysts. The PVC
Partnership will operate research and development centers in Avon Lake, Ohio,
and Pottstown, Pennsylvania, pending decisions on consolidating operations to
one location. The laboratories are equipped with the appropriate analytical,
synthesis, polymer characterization and testing equipment, and pilot plants
which simulate the production facilities for rapid translation of technology
into improved products.
 
     Raw Materials (other than Ethylene and Chlorine). Geon and OxyChem will
transfer to the PVC Partnership certain agreements providing for the supply of a
variety of materials used to manufacture PVC resin products. Because these
materials generally have adequate alternative sources of supply, not all such
materials will be purchased under multi-year contracts.
 
COMPOUNDING PARTNERSHIP
 
     Geon and OxyChem will each contribute to the Compounding Partnership its
Compounding Contributed Business consisting of its PVC powder/dry blend compound
manufacturing and supply businesses and certain related assets. The PVC
compounds to be manufactured by the Compounding Partnership will be made by
combining PVC resin with certain additives. These compounds will generally be
rigid and impact resistant. The Compounding Partnership's compound products will
be fabricated into finished products by other manufacturers using the extrusion
process. Rigid extrusion PVC compounds are commonly used in pipe, window frames,
vertical blinds, and other construction applications.
 
     Geon. Geon will contribute to the Compounding Partnership all of its
powder/dry blend compounding assets and its powder compound business located at
its facility in Plaquemine, Louisiana. Assuming the consolidation of Geon's
compounding assets following the Joint Venture Transactions, the capacity of
these contributed assets constitutes less than 10% of Geon's total compounding
capacity. In addition, Geon will contribute the right to use certain
transportation equipment, storage facilities, and rights of way used at the
plants and certain contractual rights to the Compounding Partnership.
 
     OxyChem. OxyChem will contribute substantially all of its compounding
assets and its powder compound business located at its Pasadena, Texas,
facility. In addition, OxyChem will contribute certain transportation equipment
and rights of way used at the Pasadena facility and certain contractual rights
to the Compounding Partnership.

<PAGE>   59
 
BUSINESS OF THE COMPOUNDING PARTNERSHIP FOLLOWING THE JOINT VENTURE TRANSACTIONS
 
     Using the assets contributed to it by Geon and OxyChem, the Compounding
Partnership will produce and purchase or otherwise acquire, use, distribute,
market, and exchange PVC powders into all markets, including, without
limitation, basic construction and remodeling markets for use in pipe, windows,
doors, fences, and siding. The Compounding Partnership is expected to have
manufacturing capacity totaling 420 million pounds. The Plaquemine, Louisiana,
facility will have manufacturing capacity of 140 million pounds of powder
compound and the Pasadena, Texas, facility will have manufacturing capacity of
280 million pounds of powder compound. The business of the Compounding
Partnership will not include (i) any semi-rigid and flexible PVC molding
powders, PVC blends, PVC alloys, PVC copolymers or other polymers, such as
polyurethanes, polyethylene, polypropylene, ethyl vinyl acetate, copolymers,
natural and synthetic rubbers, thermoplastic elastomers or polyurethane rubber,
(ii) PVC powder compounds for use in any of the following processes: slush
molding, rotational molding, injection molding, casting, fluid bed coating,
electrostatic fluidized bed, electrostatic spray, non-electrostatic spray, or
flock gun, or (iii) the business of the PVC Partnership as described above.
 
     Sales and Marketing. The Compounding Partnership will sell its compounds to
third parties who are expected to use such compounds in a variety of
applications. In addition, the Compounding Partnership will toll PVC resin into
powder compound for the PVC Partnership to support certain pipe segment
customers of the PVC Partnership and will also support other customers of the
PVC Partnership as agreed to by the Partnerships.
 
     Customer Support. The Compounding Partnership will support its
manufacturing of compound products by providing service to customers through
enhanced customer and technical support. This support will be provided by Geon
and its employees pursuant to the Compounding Partnership Agreement. This
relationship will make available to the customers of the Compounding Partnership
all of Geon's expertise in processing PVC compounds into end products. Moreover,
the relationship between Geon and the Compounding Partnership may create
opportunities for the Compounding Partnership to coordinate with Geon's other
compound businesses and the PVC Partnership. Geon believes its compound customer
support capabilities are respected within the industry and offer an advantage to
the customers of the Compounding Partnership.
 
     Research and Development. Through Geon, the Compounding Partnership will
have substantial research and development capabilities. Geon's efforts will be
devoted to: (i) providing support to the Compounding Partnership's manufacturing
plants for cost reduction, productivity, and quality improvement programs, (ii)
providing quality technical services to assure the continued success of the
Compounding Partnership's products for its customers' applications, (iii)
providing technology for improvements to the Compounding Partnership's products,
processes, and applications, and (iv) developing new products to satisfy defined
market needs. Geon will operate a research and development center in Avon Lake,
Ohio. The laboratory is equipped with modern analytical, synthesis, polymer
characterization and testing equipment, and pilot plants and polymer compounding
operations which simulate the production facilities for rapid translation of new
technology into new products.
 
     Raw Materials. Although both Geon and OxyChem will transfer to the
Compounding Partnership certain agreements providing for the supply of a variety
of additives used to manufacture compound products, these materials generally
have adequate alternative sources of supply and will not be purchased under
multi-year contracts.

Delaware corporation as its wholly-owned subsidiary to become its limited
partner in the Compounding Partnership ("OCC Compounding Limited Partner"). Geon
and OxyChem also agreed that Geon will (i) incorporate three Delaware
corporations as wholly-owned subsidiaries to become its limited partner in the
PVC Partnership ("Geon PVC Limited Partner") and its general partner and limited
partner in the Compounding Partnership ("Geon Compounding General Partner" and
"Geon Compounding Limited Partner," respectively), and (ii) incorporate two
Canadian corporations, one of which will be a wholly-owned subsidiary of Geon
Canada Inc. ("Canco 1") and one of which will be a wholly-owned subsidiary of
LaPorte Chemicals ("Canco 2"), to facilitate the transfer of Geon's Canadian
assets to the PVC Partnership.
 
     Pursuant to the Master Agreement, OCC PVC General Partner, OCC PVC Limited
Partner, and Geon PVC Limited Partner will form the PVC Partnership, and OCC
Compounding Limited Partner, Geon Compounding General Partner, and Geon
Compounding Limited Partner will form the Compounding Partnership.
 
     On the closing date, Geon and OxyChem have agreed to cause the execution
and delivery by the appropriate parties of (i) certain partnership agreements,
asset contribution agreements, parent agreements, and asset sale agreements and
(ii) a variety of other agreements that have been negotiated by Geon and
OxyChem, which relate, among other things, (a) to the transfer of assets and
assumption of liabilities contemplated by the Asset Contribution Agreements and
(b) to services, utilities, and infrastructure to be shared or supplied, and
products to be purchased or sold, between the PVC Partnership or the Compounding
Partnership and Geon or OxyChem (collectively, the "Related Agreements").
 
     The Master Agreement contemplates that, pursuant to the Asset Contribution
Agreements, Geon and OxyChem will on the closing date make, or cause to be made,
the contributions of the Contributed Assets to the Partnerships, subject to the
assumption of certain liabilities by the Partnerships. See "The PVC Asset
Contribution Agreements" and "The Compounding Asset Contribution Agreements." In
exchange for the contributions by Geon to the Partnerships, Geon PVC Limited
Partner will receive 24 PVC units, representing a 24% interest in the PVC
Partnership, Geon Compounding General Partner will receive one Compounding unit,
representing a 1% interest in the Compounding Partnership, and Geon Compounding
Limited Partner will receive 89 Compounding units, representing an 89% interest

     Partnership, the Compounding Partnership, Canco 1, Canco 2, or Geon, as the
     case may be, of the applicable Contributed Business at and after the
     closing, and no proceeding seeking any such injunction or order will be
     pending or threatened;
 
          (ii) Geon and OxyChem will have obtained and effected all government
     licenses and consents required from any governmental authority (including

     under the Master Agreement and the Related Agreements and required to allow
     for the prudent and uninterrupted operation of the Contributed Business by
     the PVC Partnership, the Compounding Partnership, Canco 2, or Geon, as the
     case may be, after the closing in a manner consistent with past practices,
     except for those government licenses and consents, the absence of which is
     not, in the aggregate, reasonably likely to have a material adverse effect
     with respect to such Contributed Business;
 
          (iii) the waiting period applicable to the transactions contemplated
     by the Master Agreement and the Related Agreements under the Competition
     Act (Canada) will have expired or been terminated, approval under the
     Competition Act (Canada), as amended, will have been obtained, the
     investigation commenced by the FTC with respect to matters identified in
     the subpoena civil investigative demand issued by the FTC to Geon and

     would reasonably likely to have, a material adverse effect on any party or
     that would, or would be reasonably likely to, materially frustrate the
     financial or other business benefits reasonably expected to be derived by
     any party from the transactions contemplated by the Master Agreement;
 
          (iv) Geon will have received any necessary approval of its

TERMINATION
 
     Termination.  The Master Agreement may be terminated and the transactions
contemplated therein and in the Related Agreements may be abandoned at any time
prior to the closing:
 
          (i) by the written consent of Geon and OxyChem;
 
          (ii) by Geon if there has been a material misrepresentation or a
     breach of an agreement by OxyChem in the Master Agreement that (a) if such
     misrepresentation or breach existed on the closing date, would constitute a
     failure to satisfy the conditions to closing and (b) has not been cured and
     cannot reasonably be cured within 30 days after all other conditions to
     closing have been satisfied;
 
          (iii) by Geon if the Geon Board has not duly authorized and approved
     the Master Agreement and the Related Agreements and the transactions
     contemplated thereby on or before May 1, 1999;
 
          (iv) by OxyChem if there has been a material misrepresentation or a
     breach of an agreement by Geon in the Master Agreement that (a) if such
     misrepresentation or breach existed on the closing date, would constitute a
     failure to satisfy the conditions to closing set forth in clauses (ii) and
     (iii) above under "Conditions Precedent to Obligations of OxyChem" and (b)
     has not been cured and cannot reasonably be cured within 30 days after all
     other conditions to closing have been satisfied;
 
          (v) by OxyChem if OPC's Board has not duly authorized and approved the
     Master Agreement and the Related Agreements and the transactions
     contemplated thereby on or before May 1, 1999;
 
          (vi) by Geon or by OxyChem if prior to the closing, any final,
     non-appealable order or injunction is issued by any federal or state court
     of competent jurisdiction in the United States or Canada or by any
     authority, or any legal requirement will be promulgated or enacted by any
     authority in the United States or Canada, that would have the effect of
     prohibiting or making unlawful the performance of the Master Agreement, the
     execution, delivery, or performance of any Related Agreement or the
     consummation of the closing;
 
          (vii) by either Geon or OxyChem if Geon has not received any necessary
     approvals from its stockholders on or before May 1, 1999; and
 
          (viii) by either Geon or OxyChem in the event that the closing does
     not occur for any reason on or before July 1, 1999; provided, however, that
     if the closing does not occur due to the act or omission of one of the
     parties, that party may not terminate the Master Agreement pursuant to the
     provisions of this clause.
 
     Effect of Termination. In the event of any termination of the Master
Agreement, the Master Agreement will become wholly void and of no further force
and effect and there will be no liability on the part of Geon or OxyChem or any
of its subsidiaries or their respective officers or directors; provided,
however, that upon any such termination the obligations of the parties with
respect to expenses relating to the transaction, payments relating to the
Pasadena Subject Business, and confidentiality under the Master Agreement will
remain in full force and effect.
 
                                       54
<PAGE>   66
 
EXPENSES AND OTHER PAYMENTS
 
     Each of Geon and OxyChem will be solely responsible for and will bear all
of its own respective costs, fees, and expenses incurred in connection with the
negotiation, execution, and delivery of the Master Agreement, the satisfaction
of the conditions to closing under the Master Agreement, and the consummation of
the transactions contemplated by the Master Agreement. Geon and OxyChem have
agreed that they will split equally certain fees and expenses relating to
antitrust analysis and related services regardless of whether or not the closing
occurs. Geon will bear the first $800,000 of fees and expenses in connection
with the refinancing of certain financing arrangements related to Geon's
LaPorte, Texas, facility.
 
     Pursuant to the Master Agreement, if the closing does not occur for any
reason (other than for a material misrepresentation by Geon, a breach of a
material agreement by OxyChem, or the failure of OPC's Board to approve the
Master Agreement and Related Agreements), Geon will pay OxyChem the lesser of
(i) $165,000 per month commencing on the date of termination of the Master
Agreement and ending on the earlier to occur of (a) three months from the date
of the termination of the Master Agreement and (b) the date on which OxyChem
enters into a long-term tolling arrangement covering the Pasadena Subject
Business and (ii) the actual costs incurred by OxyChem and its affiliates during
such period related to obtaining a third-party tolling arrangement covering the
Pasadena Subject Business.
 
AMENDMENT AND WAIVER
 
     All waivers, modifications, amendments, or alterations of the Master
Agreement will require the written approval of each of Geon and OxyChem. No
action taken by Geon or OxyChem will be deemed to constitute a waiver by such
party of compliance with any representations, warranties, covenants, or
agreements contained in the Master Agreement and any documents delivered
pursuant to the Master Agreement and in connection with the closing. The waiver
by Geon or OxyChem of a breach of any provision of the Master Agreement will not
operate or be construed as a waiver of any subsequent breach.

     The following is a summary of the material provisions of the Asset
Contribution Agreements between Geon, Geon PVC Limited Partner, and the PVC

the PVC Partnership (see " -- Assumed Liabilities" below), Geon or OxyChem may
by law or agreement continue as the primary obligor of certain of these
liabilities. Although the PVC Partnership will indemnify each of Geon and
OxyChem, and their respective affiliates, for the liabilities assumed by the PVC
Partnership (see " -- Indemnification" below), Geon and OxyChem could be liable
with respect to any such liabilities if the PVC Partnership is unable to satisfy
its indemnification obligations.
 
CONTRIBUTED ASSETS
 
     Geon and OxyChem, on behalf of its subsidiaries, (each a "Contributor")
will contribute to the PVC Partnership, its PVC Contributed Assets, consisting
of all of the assets, rights, and properties used or held for use in the
contemplated operation and conduct of its PVC Contributed Business, other than
certain excluded assets. See "Businesses and Assets to be Contributed to the

of each Contributor will be assumed by the PVC Partnership in connection with
the transfer of PVC Contributed Assets to it, and the PVC Partnership will agree

     the PVC Contributed Assets or the PVC Contributed Business except for
     certain health, safety, and environmental claims that are related to

          (v) except for certain health, safety, and environmental claims,

          (xi) any other liability specifically assumed by the PVC Partnership

OTHER AGREEMENTS
 
     Employment Matters. In accordance with the terms of the Master Agreement,
the PVC Partnership will offer employment to employees of the Contributor (i)
whose work relates solely and exclusively to, or substantially in support of,
the PVC Contributed Assets and (ii) who are immediately prior to the closing
date either in the active employment of a Contributor or on short-term
disability leave, sick leave, or other temporary leave of absence. In addition,
pursuant to the terms of the Geon PVC Asset Contribution Agreement, the PVC
Partnership will offer employment to all employees who are part of a collective
bargaining unit represented by certain unions and who are immediately prior to
the closing date either in active employment of the Contributor or on short-term
disability leave, sick leave, or other temporary leave of absence approved by
the Contributor. Any employee that accepts such offer is referred to as a "PVC
Partnership Employee."
 
     Each Contributor will remain solely responsible for, (i) with respect to
OxyChem, any liability with respect to OxyChem employees who do not become PVC
Partnership Employees and, with respect to Geon, certain non-union employees of
Geon who are not plant employees and whose work relates directly to the support
of the Contributed Assets and who do not become PVC Partnership Employees,
including any liability for severance benefit payments and any costs associated
with violations of any legal requirements; (ii) any bonus or executive
compensation, if any, to employees covered by a Contributor's bonus or executive
compensation programs; and (iii) any liability related to the termination of any
employees of a Contributor or any of its affiliates at any time prior to the

employees pursuant to any applicable severance plan and any costs associated
with violations of any legal requirements. With respect to employees who become
PVC Partnership Employees, each Contributor will pay bonus or executive
compensation earned in 1998. Each Contributor will promptly reimburse the PVC
Partnership for a pro-rata portion of any bonus or executive compensation paid
by the PVC Partnership that is earned in 1999 by PVC Partnership Employees based
on the months of employment in 1999 with the Contributor.
 
                                       57
<PAGE>   69
 
     Any PVC Partnership Employee whose employment is terminated by the PVC
Partnership within six months after the closing date will be entitled to receive
a severance benefit from the PVC Partnership not less than the benefits, if any,
provided under the severance plan of the Contributor in effect as of the closing
date.
 
     Under the Geon PVC Asset Contribution Agreement, Geon and the PVC
Partnership agree that they will satisfy their respective obligations, if any,
under the National Labor Relations Act regarding union employees. The PVC
Partnership will recognize each union, and each union employee will participate
in such plans and programs as are applicable to the union employees in
accordance with the terms and conditions negotiated by the PVC Partnership.
 
     Except with respect to PVC Assumed Liabilities (other than PVC Assumed
Liabilities described in clause (v) on the preceding page), each Contributor
will retain the sole responsibility for, and will 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 the Contributor and their covered
dependents, including "qualified beneficiaries" within the meaning of section
607(3) of ERISA, with respect to claims incurred prior to the closing date. In
addition, except with respect to PVC Assumed Liabilities (other than PVC Assumed
Liabilities described in clause (v) on the preceding page), each Contributor
will 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 for,
Exposure Claims (as defined below) by or any other item of compensation or
benefits payable under any Contributor plan to (i) any employee of the
Contributor after the closing date and (ii) any former employee of the
Contributor who retired, died, became disabled, or otherwise terminated
employment prior to the closing date. Expenses and benefits relating to such
claims incurred by PVC Partnership Employees and their covered dependents
attributable to employment with the PVC Partnership on or after the closing date
will be the sole responsibility of the PVC Partnership under the terms of its
benefit plans.
 
     Support Services. For two years from the date of the PVC Asset Contribution
Agreements, the PVC Partnership will have the right to purchase services from
the businesses being retained by the Contributors at full cost and otherwise on
arm's-length terms in all cases where it is reasonable for such retained
businesses to provide the services. In no event will the services be in excess
of the quantity of, or in kind other than, the services provided to the PVC
Contributed Businesses prior to the closing date. Similarly, for a period of two
years from the date of the PVC Asset Contribution Agreements, the businesses
retained by the Contributors will have the right to purchase services from the
PVC Partnership at full cost and otherwise on arm's-length terms in all cases
where it is reasonable for the PVC Partnership to provide the services.
 
INDEMNIFICATION
 
     Subject to the terms described below, each Contributor will agree, to the
fullest extent permitted by applicable law, to indemnify, defend, and hold
harmless the PVC Partnership and its affiliates and their respective officers,
directors, and employees from, against, and in respect of any liabilities
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 a Contributor or any of its affiliates subject to certain
     materiality qualifications in the PVC Asset Contribution Agreements,
     certain Assignment and Assumption Agreements, the PVC Master Intellectual
     Property Agreements, or the Master Agreement, provided however that any
     liability arising out of, in connection with, or relating to any breach of
     warranties in any Assignment and Assumption Agreement that is not a breach
     of warranties under the PVC Asset Contribution Agreements will not be
     indemnifiable hereunder;
 
                                       58
<PAGE>   70
 
          (ii) any failure of a Contributor or any of its affiliates to perform

     Intellectual Property Agreements, or the Master Agreement;
 
          (iii) excluded assets;
 
          (iv) any exposure of any person to PVC, VCM, or chemical substances in
     connection with a PVC Contributed Business, to the extent such liability is
     attributable to the period prior to the closing date ("Exposure Claim");
 
          (v) any product exposure claim that is not an assumed liability;
 
          (vi) certain health, safety, and environmental claims that are related
     to pre-closing liabilities that are not PVC Assumed Liabilities;
 
          (vii) any third party claim (other than Exposure Claims, product
     exposure claims, and certain health, safety, and environmental claims) that
     is related to a pre-closing liability and that is not a PVC Assumed
     Liability;
 
          (viii) any obligation (A) for the payment of severance benefits to
     employees of a Contributor or any of its affiliates, except as otherwise
     agreed to by the parties, (B) attributable to a Contributor's or any of its
     affiliate's employment of any employee, agent, or independent contractor
     prior to the closing date, or (C) relating to employee matters assumed by a
     Contributor or its affiliates; or
 
          (ix) any taxes of a Contributor, a contributed subsidiary, or a PVC
     partner for any taxable period or portion thereof ending before the closing
     date or arising from any of the transactions contemplated by the PVC Asset
     Contribution Agreements.
 
     The indemnification obligations of each Contributor under their respective
PVC Asset Contribution Agreements described in clause (i) above are subject to
the following limitations: each Contributor, in the aggregate, will not have any
indemnification obligation under clause (i) above for any individual liability
unless the amount of such liability exceeds $100,000 (the "Individual Basket"),
and until the total of all liabilities under clause (i) equals an aggregate
deductible of $500,000 (the "Deductible"); and provided further that the parties
agree that the amount of liability for which indemnification may be sought for
breach of any representation and warranty under clause (i) will be calculated
taking into account the Individual Basket and Deductible without regard to any
qualification or exception regarding materiality or material adverse effect
qualification contained in such representation and warranty.
 
     Subject to the other indemnification provisions of the PVC Asset
Contribution Agreements, the PVC Partnership also will indemnify, to the fullest
extent permitted by law, each 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 them arising out of or relating
to: (i) any misrepresentation in or breach of the representations and warranties
of the PVC Partnership or the failure of the PVC Partnership to perform any of
its covenants or obligations contained in the PVC Asset Contribution Agreements,
certain Assignment and Assumption Agreements, the PVC Master Intellectual
Property Agreements, or the Master Agreement, (ii) PVC Assumed Liabilities, or
(iii) any health, safety, or environmental claim to the extent arising out of
the PVC Partnership's exacerbation or acceleration of such health, safety, or
environmental claim.
 
     The rights provided to the PVC Partnership and the Contributors will be the
sole remedy for such party for breach of representation and warranty by or
covenant or obligation of the other party under the PVC Asset Contribution
Agreements, certain Assignment and Assumption Agreements, the PVC Master
Intellectual Property Agreement, and the Master Agreement or arising in
connection with or related in any way to the matters in the PVC Asset
Contribution Agreement.

PAYMENT OF CERTAIN EXPENSES AND TAXES
 
     Subject to the following provisions, each Contributor will be responsible
for all taxes attributable to that Contributor's or its affiliate's ownership,
use, or transfer of the PVC Contributed Assets or operation of its PVC
Contributed Business prior to the closing date, and the PVC Partnership will be
responsible for all taxes attributable to the PVC Partnership's ownership, use,
or transfer of the PVC Contributed Assets or operation of the PVC Contributed
Businesses after the closing date. All sales, use, value added, excise,
transfer, land transfer, or other similar taxes incurred or arising in
connection with the transfer of the PVC Contributed Assets to the PVC
Partnership will be borne solely by the Contributor. All real property taxes,
personal property taxes, ad valorem taxes, and other similar taxes (or payments
in lieu of such taxes) assessed on any of the PVC Contributed Businesses or PVC
Contributed Assets in the tax period in which the closing date occurs will be
prorated between the PVC Partnership and the appropriate Contributor as of the
closing date. The PVC Partnership will pay any title or recordation fees in
connection with the transfer of the PVC Contributed Assets. The PVC Partnership
will also pay for any surveys of the fee interests and any related easements or
rights-of-way that are requested or ordered by the PVC Partnership.
 
                         THE PVC PARTNERSHIP AGREEMENT
 
     The following is a summary of the material provisions of the PVC
Partnership Agreement.
 
GENERAL
 
     In connection with the formation of the PVC Partnership, Geon PVC Limited
Partner, OCC PVC General Partner, and OCC PVC Limited Partner will enter into
the PVC Partnership Agreement which will govern the management and operations of
the PVC Partnership. The PVC Partnership will continue in existence until its
dissolution in accordance with the terms of the PVC Partnership Agreement. See
" -- Dissolution and Termination." The general partner of the PVC Partnership
will be OCC PVC General Partner, an indirect, wholly-owned subsidiary of
OxyChem.
 
GOVERNANCE
 
     The PVC Partnership Governance Committee will manage and control the
business, property, and affairs of the PVC Partnership, including the
determination and implementation of the PVC Partnership's strategic direction.
The PVC Partners will exercise their authority to manage and control the PVC
Partnership only through the PVC Partnership Governance Committee. The PVC
Partnership Governance Committee will consist of six representatives, three of
whom are representatives of Geon PVC Limited Partner and three of whom are
representatives of OCC PVC General Partner. See "Management of
Partnerships -- PVC Partnership."
 
     In general, the approval of two or more representatives acting for OCC PVC
General Partner will be sufficient for the PVC Partnership Governance Committee
to take any action. However, the PVC Partnership Governance Committee will not
be permitted to take certain actions unless such actions are approved by two
representatives of Geon PVC Limited Partner and two representatives of OCC PVC
General Partner, as described below. See " -- Unanimous Voting Requirements."
This means, in effect, that OxyChem's representatives will control the PVC
Partnership Governance Committee (and, as a result, the PVC Partnership) except
where the approval of Geon's representatives is required.
 
UNANIMOUS VOTING REQUIREMENTS
 
     Unless approved by two or more representatives of each of Geon PVC Limited
Partner and OCC PVC General Partner, the PVC Partnership Governance Committee
may not directly or indirectly take (or commit to take), and none of the PVC
Partnership, any subsidiary thereof, or any person acting in
 
                                       60
<PAGE>   72
 
the name of or on behalf of any of them, directly or indirectly, may take or
commit to take any of the following actions (whether in a single transaction or
a series of related transactions):
 
          (i) to cause the PVC Partnership, directly or indirectly, to engage,
     participate, or invest in any business outside the scope of its business as
     described in the PVC Partnership Agreement;
 
          (ii) to approve any strategic plan, as well as any amendments or
     updates thereto;
 
          (iii) 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, unless otherwise provided by the PVC Partnership
     Agreement; provided, however, that no such approval will be required in
     respect of a disposition of assets in excess of such threshold amount if
     the Chief Executive Officer of the PVC Partnership, acting through the PVC
     Partnership Governance Committee, obtains an opinion, in form and substance
     reasonably satisfactory to the representatives of both OCC PVC General
     Partner and Geon PVC Limited Partner, 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 PVC Partnership for such assets, taking into
     consideration all of the terms of such disposition; provided, further,
     however, that in no event will a disposition of assets in excess of such
     threshold amount be made to an affiliate of OCC PVC General Partner or Geon
     PVC Limited Partner;
 
          (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
     Geon does not approve such an acquisition or expenditure, OxyChem may cause
     the PVC Partnership to proceed with the acquisition or expenditure if all
     amounts over $1 million are paid by OxyChem and, in such an event, the
     amounts paid will be deemed to be additional capital contributions, and
     OxyChem's interest in the PVC Partnership will be increased by an amount
     determined in accordance with an agreed formula as specified in the PVC
     Partnership Agreement;
 
          (v) to require capital contributions to the PVC Partnership (other
     than contributions contemplated by the PVC Asset Contribution Agreements or
     an approved strategic plan or to achieve or maintain compliance with
     certain laws) within any fiscal year if the total of such contributions
     required from the partners within that year would exceed $10 million to the
     extent the aggregate principal amount of the PVC Partnership's borrowings
     is less than $575 million;
 
          (vi) to make borrowings under the PVC Partnership's bank credit
     facilities, its uncommitted lines of credit or any credit facility or debt
     instrument of the PVC Partnership that finances or refinances all or any
     portion of the PVC Partnership's credit facilities, or to enter into any
     capitalized lease or similar off-balance sheet financing arrangement at any
     time if the aggregate principal amount of such borrowings outstanding at
     such time would exceed $575 million;
 
          (vii) to enter into interest rate protection or other hedging
     agreements unless otherwise provided in the PVC Partnership Agreement;
 
          (viii) except as otherwise provided in the PVC Partnership Agreement,
     to cause the PVC Partnership or any subsidiary of the PVC Partnership to
     issue, sell, redeem, or acquire any units or other equity securities (or
     any rights to acquire, or any securities convertible into or exchangeable
     for, units or other equity securities);
 
          (ix) except in connection with the dissolution of the PVC Partnership,
     to make PVC Partnership distributions that are not contemplated in an
     approved strategic plan or under the cash management and credit and deposit
     facilities agreement as contemplated in the Master Agreement;
 
          (x) to initiate or settle any litigation or governmental proceedings
     if the effect thereof could reasonably be expected to be material to the
     financial condition of the PVC Partnership;
 
                                       61
<PAGE>   73
 
          (xi) to change the PVC Partnership's method of accounting or to make
     certain tax elections;
 
          (xii) to create or change the authority of any auxiliary committee;
 
          (xiii) to merge, consolidate, or convert the PVC Partnership or any
     subsidiary thereof with or into any other entity (other than a wholly-owned
     subsidiary of the PVC Partnership);
 
          (xiv) to file a petition in bankruptcy or seek any reorganization,
     liquidation, or similar relief on behalf of the PVC Partnership or any
     subsidiary of the PVC Partnership; or to consent to the filing of a
     petition in bankruptcy against the PVC Partnership or any subsidiary of the
     PVC Partnership; or to consent to the appointment of a receiver, custodian,
     liquidator, or trustee for the PVC Partnership or any subsidiary thereof or
     for all or any substantial portion of their respective property;
 
          (xv) to enter into any raw material supply contract with a term of two
     years or longer that calls for payments by the PVC Partnership that exceed
     $50 million in any fiscal year;
 
          (xvi) except in connection with the dissolution of the PVC
     Partnership, to enter into an indemnification agreement whereby the PVC
     Partnership agrees (a) to indemnify a partner, (b) to an indemnification
     outside of the ordinary course of business, or (c) to an indemnification
     for any item that could cause obligations of the PVC Partnership in excess
     of $5 million;
 
          (xvii) except in connection with the dissolution of the PVC
     Partnership to authorize prepayments of the loans to the PVC Partnership
     guaranteed by Geon under the cash management and credit and deposit
     facilities agreement; or
 
          (xviii) to approve certain loans to Geon or OxyChem as described in
     the PVC Parent Agreement.
 
     Although unanimous approval by all six members of the PVC Partnership
Governance Committee is never required, Geon and OxyChem have referred to the
requirements described above as "unanimous voting requirements" because two
representatives of each of OCC PVC General Partner and Geon PVC Limited Partner
must agree on any action taken in respect of such enumerated matters.
 
TRANSACTIONS WITH AFFILIATES
 
     Upon receipt of any required approval by the PVC Partnership Governance
Committee, all contracts and transactions between the PVC Partnership and a
partner or its affiliates (including the Related Agreements) 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 the PVC
Partnership Agreement or the existence of the PVC Partnership.
 
OFFICERS
 
     The executive officers of the PVC Partnership will consist of a Chief
Executive Officer ("CEO") and other officers as determined from time to time by
the PVC Partnership Governance Committee. See "Management of the
Partnerships -- PVC Partnership." The PVC Partnership Governance Committee may
select natural persons who are (or upon becoming an officer will be) agents or
employees of the PVC Partnership to be designated as officers of the PVC
Partnership, with such titles as the PVC Partnership Governance Committee will
determine. The CEO may be removed (i) at any time by the PVC Partnership
Governance Committee, with or without cause, whenever in the judgment of the PVC
Partnership Governance Committee the best interests of the PVC Partnership would
be served thereby or (ii) by Geon PVC Limited Partner, at any time after 12
months have passed following the delivery of written notice from Geon PVC
Limited Partner to the PVC 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 PVC
Limited Partner) within such 12 month period. Either OCC
                                       62
<PAGE>   74
 
PVC General Partner or Geon PVC Limited Partner may, by action of two or more of
its representatives, remove from office any executive officer of the PVC
Partnership who takes or causes the PVC Partnership to take any action that
requires the approval of two or more representatives of each of Geon PVC Limited
Partner and OCC PVC General Partner without such approval.
 
     The CEO will 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 vacancy, OCC PVC General Partner will designate the CEO. The CEO will
not be required to be an employee of the PVC Partnership but will be required to
devote substantially all of his or her efforts to the PVC Partnership's
business.
 
     The CEO will 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 PVC Partnership, including
its day-to-day operations, in a manner consistent with the annual budget and the
most recently approved strategic plan. The PVC Partnership Governance Committee
will establish and maintain a compensation plan for the CEO and the other key
employees of the PVC Partnership. The level of compensation provided in such
plan for the CEO and the other key employees of the PVC Partnership will be
consistent with levels obtaining in the industry generally for comparably
situated persons, and such plan will establish incentive compensation goals
intended to reward the CEO and the other key employees of the PVC Partnership
for achievement of the synergies and objectives set forth in the strategic plan.
 
STRATEGIC PLANS, ANNUAL BUDGETS, AND EXPENSES
 
     The PVC Partnership will be managed in accordance with a five-year
strategic plan that will be updated annually under the direction of the CEO and
presented for approval by the PVC Partnership Governance Committee no later than
45 days prior to the start of the first fiscal year covered by the updated plan.
The strategic plan must be approved each year by at least two representatives of
each of Geon PVC Limited Partner and OCC PVC General Partner. The strategic plan
will establish the strategic direction of the PVC 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. The strategic plan also will establish the PVC
Partnership's policy regarding the timing and amount of any distributions to the
partners. However, the partners contemplate that the strategic plan will provide
that, except for debt redemption or prepayment goals contained therein, the
amount of cash available for distribution as of the end of each month will be
distributed to the partners pro rata. Except for entering into the Related
Agreements, the PVC Partnership will not, on other than an arm's-length basis,
enter into, or waive any material rights under, any agreement between the PVC
Partnership and a partner or its affiliates unless the taking of such action is
specifically contemplated by an approved strategic plan.
 
     In addition, the executive officers of the PVC Partnership will prepare an
annual budget for each fiscal year. Each annual budget will include an operating
budget and capital expenditure budget, provided that each annual budget will be
consistent with the information for such fiscal year included in the strategic
plan most recently approved by the PVC Partnership Governance Committee. Unless
otherwise provided in the most recently approved strategic plan, each annual
budget will utilize a format and provide a level of detail consistent with the
PVC Partnership annual budget for the 1998 fiscal year.
 
     If, after the fifth anniversary of the date of the PVC Partnership
Agreement, the PVC Partnership Governance Committee has not agreed upon and
approved an updated strategic plan within 12 months after the beginning of the
first fiscal year that would have been covered by such plan, then Geon PVC
Limited Partner and OCC PVC General Partner will submit their disagreements to
non-binding mediation by a neutral third party (the "Mediator"), who will be
mutually agreed upon by OCC PVC General Partner and Geon PVC Limited Partner (or
by certain third parties if OCC PVC General Partner and Geon PVC Limited Partner
cannot agree). Within 20 days of selection of the Mediator, two persons having
decision-making authority on behalf of each of OCC PVC General Partner and Geon
PVC
 
                                       63
<PAGE>   75
 
Limited Partner will meet with the Mediator and agree upon procedures and a
schedule for attempting to resolve the differences between OCC PVC General
Partner and Geon PVC Limited Partner. They will continue to meet thereafter on a
regular basis until (i) agreement is reached by OCC PVC General Partner and Geon
PVC Limited Partner (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 the PVC
Partnership Agreement that would have been covered by the updated plan for which
agreement was not reached, and OCC PVC General Partner or Geon PVC Limited
Partner will determine and notify the other and the Mediator in writing that no
agreement resolving the dispute is likely to be reached (a "Deadlock Notice").
Following any such Deadlock Notice, either OCC PVC General Partner or Geon PVC
Limited Partner may elect to dissolve the PVC Partnership. See " -- Dissolution
and Termination." In no event will OCC PVC General Partner or Geon PVC Limited
Partner have the right to commence the above described procedures until after
the fifth anniversary of the date of the PVC Partnership Agreement.
 
     Generally, all PVC Partnership expenses (both operating and capital
expenses), regardless of whether included in any strategic plan or annual
budget, will be funded from operating cash flows or authorized borrowings under
available lines of credit, unless otherwise agreed by the PVC Partnership
Governance Committee or, in certain circumstances, determined by the CEO. See
"-- Capital Contributions."
 
DISTRIBUTION OF AVAILABLE NET OPERATING CASH
 
     Distributions to the partners of cash or property arising from a
liquidation of the PVC Partnership will be made in accordance with the capital
account balances of the partners.
 
     Any amount otherwise distributable to a partner as described above will be
applied by the PVC Partnership to satisfy any of the following obligations that
are owed by such partner or its affiliate to the PVC Partnership and that are
not paid when due: (i) any interest or principal due on any indebtedness for
borrowed money of a partner or any affiliate of such partner to the PVC
Partnership; (ii) any payment pursuant to a PVC Asset Contribution Agreement
that has been finally determined to be due; and (iii) any capital contribution
required pursuant to the PVC Partnership Agreement (other than pursuant to a PVC
Asset Contribution Agreement).
 
CAPITAL CONTRIBUTIONS
 
     Pursuant to the PVC Asset Contribution Agreements, upon the formation of
the PVC Partnership, the partners will contribute to the PVC Partnership the PVC
Contributed Assets, subject to the assumption by the PVC Partnership of the PVC
Assumed Liabilities, in exchange for an aggregate of 100 PVC units. Geon and
OxyChem intend that the contribution of assets, subject to liabilities, will
qualify as a tax-free contribution under Section 721 of the Code in which no
partner will recognize gain or loss. The partners will agree that the PVC
Partnership will so file its tax return, and each partner will agree to file its
tax return on the same basis and to maintain such position consistently at all
times thereafter.
 
     Subject to the requirement that two representatives of each of Geon PVC
Limited Partner and OCC PVC General Partner approve any capital contributions
that would exceed a total of $10 million in any fiscal year, the PVC Partnership
Governance Committee, on behalf of the PVC Partnership, may issue a written
notice to the partners calling for an additional capital contribution to the PVC
Partnership. The aggregate amount of such additional contribution will be
apportioned among the partners pro rata. In addition, subject to the limitation
that the approval of two representatives of each of Geon PVC Limited Partner and
OCC PVC General Partner is required for capital contributions in excess of a
total of $10 million in any fiscal year, the CEO may also issue a funding notice
to the PVC Limited Partners, to the extent that he determines at any time that
funds are needed to fund the operations of the PVC Partnership.
 
                                       64
<PAGE>   76
 
DESCRIPTION OF PARTNERS
 
     Except as expressly set forth in the PVC Partnership Agreement, each of OCC
PVC General Partner and Geon PVC Limited Partner will agree to exercise its
authority to manage and control the PVC Partnership only through action of the
PVC Partnership Governance Committee. Neither OCC PVC General Partner nor Geon
PVC Limited Partner will have the authority, and each will agree 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 PVC Partnership or any other partner, (ii) to execute any documents on
behalf of, or otherwise bind, or purport or attempt to bind, the PVC
Partnership, or (iii) to otherwise transact any business in the name of the PVC
Partnership, in each case except pursuant to action of the PVC Partnership
Governance Committee.
 
     Geon PVC Limited Partner will be a Delaware corporation which is a direct,
wholly-owned subsidiary of Geon. Geon PVC Limited Partner will have no business
or assets except for its ownership of limited partner units in the PVC
Partnership. In the PVC Partnership Agreement, Geon PVC Limited Partner will
agree that its business will be restricted solely to the holding of its units in
the PVC Partnership and the doing of things necessary or appropriate in
connection therewith and that it will not own any assets, incur any liabilities,
or engage, participate, or invest in any business outside the scope of such
business.
 
     OCC PVC Limited Partner will be a Delaware corporation which is a
wholly-owned subsidiary of OxyChem. OCC PVC General Partner will be a Delaware
limited liability company which is a wholly-owned subsidiary of OCC PVC Limited
Partner. OCC PVC General Partner will have no business or assets except for its
ownership of general partner units in the PVC Partnership and OCC PVC Limited
Partner will have no business or assets except for its ownership of limited
partner units in the PVC Partnership. In the PVC Partnership Agreement, OCC PVC
General Partner and OCC PVC Limited Partner will each agree that its business
will be restricted solely to the holding of its units in the PVC Partnership and
the doing of things necessary or appropriate in connection therewith and that it
will not own any assets, incur any liabilities, or engage, participate, or
invest in any business outside the scope of such business.
 
INDEMNIFICATION
 
     The PVC Partnership will agree, 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 person may sustain, incur,
or assume as a result of, or relative to, any third party claim arising out of
or in connection with the business, property, or affairs of the PVC 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 the PVC
Partnership Agreement or any Related Agreement. This indemnification obligation
is not intended to, nor will it, affect or take precedence over the indemnity
provisions contained in any Related Agreement.
 
TRANSFERS AND PLEDGES
 
     Without the consent of the PVC Partnership Governance Committee, no partner
will transfer less than all of its units in the PVC Partnership, and no partner
will transfer its units for consideration other than cash. If any PVC Limited
Partner and, in the case of OCC PVC Limited Partner, its affiliated OCC PVC
General Partner, desire to transfer all of their units (together, the "Selling
Partners"), they must give written notice (the "Initial Notice") to the PVC
Partnership and the other partners (the "Offeree Partners") stating the Selling
Partners desire to transfer their units and stating the cash purchase price and
all other terms on which they are willing to sell their units (the "Offer
Terms"). Delivery of an Initial Notice will constitute the irrevocable offer of
the Selling Partners to sell their units to the Offeree Partners. The Offeree
Partners will have the option, exercisable by delivering written notice (the
"Ac-
 
                                       65
<PAGE>   77
 
ceptance Notice") of such exercise to the Selling Partners within 60 days of the
date of Initial Notice, to elect to purchase all of the units of the Selling
Partners on the Offer Terms described in the Initial Notice. The Acceptance
Notice will 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, subject to
extension in certain circumstances. The purchase price for the Selling Partners'
units will be paid in immediately available funds delivered at the closing.
 
     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 will have a further 180 days during which they may, subject to
certain conditions described below, consummate the sale of their units to a
third party purchaser at a purchase price and on such other terms that are not
substantially more favorable to the 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 180-day period, the Initial Notice will be
deemed to have expired and a new notice and offer will be required before the
Selling Partners may make any transfer of their units.
 
     Notwithstanding the above, without the need for the consent of any person,
any partner may transfer its units to any 80%-owned affiliate of such partner.
In addition, OCC PVC Limited Partner may, at its option, at any time and without
the need for the consent of any person, transfer up to 99% of its limited
partner units to OCC PVC General Partner, whereupon such limited partner units
will, without any further action, become general partner units. Promptly
following any such transfer of limited partner units, each partner will take
such actions and execute such instruments or documents (including amendments to
the PVC Partnership Agreement or supplemental agreements thereto) as may be
reasonably necessary to ensure that OCC PVC General Partner and OCC PVC Limited
Partner will, taken as a whole and following such transfer, maintain all of its
rights under the PVC Partnership Agreement as in effect immediately prior to
such transfer (including the portion of any PVC Partnership cash distributable
to such partners).
 
DEFAULT
 
     Each of the following events will constitute a "Default" and create the
rights provided for below in favor of the PVC Partnership and the partners not
in default ("Non-Defaulting Partners") against the partners in default
("Defaulting Partners"): (i) the failure by a partner to make any contribution
to the PVC Partnership as required pursuant to the PVC Partnership Agreement
(other than pursuant to a PVC Asset Contribution Agreement), which failure
continues for at least five business days from the date that the partner is
notified such contribution is overdue, (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 the PVC Partnership
Agreement), or (iii) the bankruptcy of a partner or its parent. The day upon
which a 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) is the "Default Date."
 
     Following a default, in addition to any other remedies they may have, the
Non-Defaulting Partners in their sole discretion may elect to pursue the
following remedies: (i) 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 of the units of the Defaulting Partners; 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 will have an additional 30 days following such decision
to elect an alternative remedy, and (ii) 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 clause (i) 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 PVC Partnership and thereby cause the PVC
Partnership to dissolve. See "--Dissolution and Termination."
 
     Upon any election to purchase a Defaulting Partners' units following a
Default, the purchase price that the Non-Defaulting Partners will pay to the
Defaulting Partners for their units will be an amount
 
                                       66
<PAGE>   78
 
equal to (i) the amount that the Defaulting Partners would receive in a
liquidation (assuming that any sale in connection with the dissolution of the
PVC Partnership was 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. 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 by delivering notice in writing to the
Defaulting Partners. The Non-Defaulting Partners will have 10 days from the
final determination of fair market value to elect to purchase the units of the
Defaulting Partners by delivering notice of such election in writing, and the
purchase will be consummated within 60 days from the date such notice is
delivered, subject to extension in certain circumstances. 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
other partner.
 
     If the Non-Defaulting Partners elect to dissolve the PVC Partnership as a
result of a default, any amount payable to the Defaulting Partners in the
resulting liquidation will be reduced by, without duplication, any unrecovered
damages incurred by the PVC Partnership in connection with the Default.
 
     Commencing on the Default Date and (i) prior to the Non-Defaulting
Partners' collection of damages through the exercise of their legal remedies or
otherwise, or (ii) while the Non-Defaulting Partners are pursuing their remedies
as described above, the representatives of the Defaulting Partner will not have
any voting or decisional rights with respect to matters requiring PVC
Partnership Governance Committee action, and such matters will be determined
solely by the representatives of the Non-Defaulting Partner. However, the
foregoing loss of voting and decisional rights will not occur as a result of a
default caused solely by the bankruptcy of a partner, OxyChem or Geon and, in
the case of a default resulting from the failure to make any contribution as
required by the PVC Partnership Agreement, will not apply to the voting and
decisional rights in respect of changes in the scope of the PVC Partnership's
business, the issuance, sale, redemption, or acquisition of units or other
equity securities by the PVC Partnership or any subsidiary, changes in respect
of accounting methods or tax elections, or with respect to mergers,
consolidations, or conversions of the PVC Partnership or a subsidiary thereof.
See "-- Unanimous Voting Requirements."
 
DISSOLUTION AND TERMINATION
 
     As long as Geon PVC Limited Partner is willing then to convert its units to
general partner units and thereafter serve as the PVC General Partner (who is
hereby authorized in such event to convert its units and to conduct the business
of the PVC Partnership without dissolution), the withdrawal, retirement,
resignation, dissolution, or bankruptcy of OCC PVC General Partner will not
dissolve the PVC Partnership, but rather will be a Default. See "-- Default."
The PVC Partnership will be dissolved, however, upon the happening of any one of
the following events: (i) the written determination of both OCC PVC General
Partner and Geon PVC Limited Partner to dissolve the PVC 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 Delaware Revised
Uniform Limited Partnership Act (except as provided in the first sentence of
this paragraph), (iv) the election of the Non-Defaulting Partners to effect a
dissolution of the PVC Partnership (see "-- Defaults"), or (v) after the
delivery of a Deadlock Notice by either OCC PVC General Partner or Geon PVC
Limited Partner (see "-- Strategic Plans, Annual Budgets, and Expenses"), the
written determination by either OCC PVC General Partner or Geon PVC Limited
Partner to dissolve the PVC Partnership.
 
     If the PVC Partnership dissolves, it will commence winding-up pursuant to
the appropriate provisions of the Delaware Revised Uniform Limited Partnership
Act and the procedures set forth below. Notwithstanding the dissolution of the
PVC Partnership, prior to the termination of the PVC Partnership, the business
of the PVC Partnership and the affairs of the partners, as such, will continue
to be governed by the PVC Partnership Agreement. The winding up of the PVC
Partnership will be conducted under the direction of the PVC Partnership
Governance Committee. However, (i) if OCC PVC General Partner and OCC PVC
Limited Partner are the Defaulting Partners, and Geon PVC Limited Partner is a
Non-Defaulting Partner, such winding-up will be conducted under the direction of
Geon PVC Limited
                                       67
<PAGE>   79
 
Partner, and (ii) if the dissolution is caused by entry of a decree of judicial
dissolution, the winding up will be carried out in accordance with such decree.
The person or committee conducting the winding-up of the PVC Partnership (the
"PVC Liquidator") will cause the PVC Partnership to attempt to sell all property
of the PVC Partnership. Upon dissolution of the PVC Partnership, the PVC
Liquidator will determine the time, manner, and terms of any sale or sales of
PVC 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.
 
     In the case of a dissolution and winding-up of the PVC Partnership, the PVC
Partnership's assets will be applied first to the satisfaction of the
liabilities of the PVC Partnership owing to creditors (including partners and
affiliates of 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 PVC 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 PVC Liquidator may deem advisable, such
reserves will be distributed to the partners or their assigns in the manner set
forth below. The assets will then be applied, after all allocations of profits
or losses and other certain items specified in the PVC Partnership Agreement, to
the partners in accordance with the balances in their capital accounts.
Notwithstanding the foregoing, if any partner is indebted to the PVC
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 PVC Partnership will retain such partner's distributive
share of the PVC Partnership property and apply such sums to the liquidation of
such indebtedness and the cost of operation of such PVC Partnership property
during the period of such liquidation.
 
     If dissolution occurs as a result of the delivery of a Deadlock Notice,
then, notwithstanding the foregoing and at the election of any partner,
properties will be divided and distributed in kind to the partners in accordance
with certain provisions set forth in the PVC Partnership Agreement.
 
LIMITATION OF FIDUCIARY DUTIES; NON-COMPETITION
 
     The liability of OCC PVC General Partner (including any liability of its
affiliates or its and their respective officers, directors, agents, and
employees) or of any PVC Limited Partner (including any liability of its
affiliates or its and their respective officers, agents, directors and
employees), either to the PVC Partnership or to any other partner, for any act
or omission by such partner in its capacity as a partner of the PVC Partnership
that is imposed by such partner's status as a "general partner" or "limited
partner" (as such terms are used in the Delaware Revised Uniform Limited
Partnership Act) of a limited partnership will be eliminated, waived, and
limited to the fullest extent permitted by law; provided, however, that OCC PVC
General Partner and Geon PVC Limited Partner will at all times owe to the other
a fiduciary duty in observing the requirement that two or more representatives
of each of Geon PVC Limited Partner and OCC PVC General Partner on the PVC
Partnership Governance Committee will be required to give their approval before
the PVC Partnership may undertake any of the actions requiring unanimous
approval. See "-- Unanimous Voting Requirements." OCC PVC General Partner and
Geon PVC Limited Partner will at all times owe to the other a duty to act in
good faith with respect to all matters involving the PVC Partnership.
 
     Except as described below, each partner's affiliates will be free to engage
in or possess an interest in any other business of any type, including any
business in direct competition with the PVC Partnership and to avail itself of
any business opportunity available to it without having to offer the PVC
Partnership or any partner the opportunity to participate in such business. If a
partner's affiliate desires to initiate or pursue an opportunity to undertake,
engage in, acquire, or invest in a business, activity, or operation within the
scope of the business of the PVC Partnership (except for the chlor-alkali
business) (a "PVC Related Business") by investing in or acquiring a person whose
business is a PVC Related Business, acquiring assets of a PVC Related Business,
or otherwise engaging in or undertaking a PVC Related
 
                                       68
<PAGE>   80
 
Business (a "PVC Business Opportunity"), such affiliate (such affiliate,
together with its affiliates being called the "Proposing Person") will offer the
PVC Partnership the PVC Business Opportunity.
 
     When a Proposing Person offers a PVC Business Opportunity to the PVC
Partnership, the PVC Partnership will elect to do one of the following within a
reasonably prompt period: (i) acquire or undertake the PVC Business Opportunity
for the benefit of the PVC Partnership as a whole, at the cost, expense, and
benefit of the PVC Partnership; or (ii) permit the Proposing Person to acquire
or undertake the PVC Business Opportunity for its own benefit and account
without any duty to the PVC Partnership or the other partners with respect
thereto. However, if the PVC Business Opportunity is in direct competition with
the then existing business of the PVC Partnership (a "Competing Opportunity"),
then the Proposing Person and the PVC Partnership will, if either so elects,
promptly seek to negotiate and implement an arrangement whereby the PVC
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 PVC 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 PVC Partnership.
If the PVC Partnership and the Proposing Person do not reach agreement as to
such arrangement within 30 days, the Proposing Person may acquire or undertake
the Competing Opportunity for its own benefit and account without any duty to
the PVC Partnership or the other partners with respect thereto.
 
     In addition, if the PVC 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 PVC
Related Business, then a Proposing Person may acquire or invest in such PVC
Business Opportunity without first offering it to the PVC Partnership; provided,
that, after completion of the acquisition or investment thereof, such Proposing
Person must offer the PVC Business Opportunity to the PVC Partnership as
described above. If the PVC Partnership elects to pursue such PVC Business
Opportunity, it will be acquired by the PVC Partnership its fair market value as
mutually agreed or finally determined as of the date of such acquisition.
 
     If (i) the PVC Partnership is presented with an opportunity to acquire or
undertake a PVC Business Opportunity that it determines not to acquire or
undertake, and (ii) the representatives of either OCC PVC General Partner or
Geon PVC Limited Partner, but not the other, desired that PVC Partnership
acquire or undertake such PVC Business Opportunity, then the PVC Partnership
will permit such first partner's affiliates to acquire or undertake such PVC
Business Opportunity, and such PVC Business Opportunity will be treated in the
same manner as if such partner's affiliates were a Proposing Person with respect
to such PVC Business Opportunity.
 
FINANCIAL AND ACCOUNTING MATTERS; AUDITS
 
     The fiscal year of the PVC Partnership will begin on January 1 and end on
December 31. For financial reporting purposes, the PVC Partnership will adopt a
standard set of accounting policies and will maintain separate books of account,
all in accordance with generally accepted accounting principles ("GAAP"). The
initial independent auditors of the PVC Partnership will be Arthur Andersen
L.L.P., unless and until changed by the PVC Partnership Governance Committee.
The PVC Partnership will report its operations for tax purposes utilizing the
accrual method of accounting. The PVC Partnership will give each partner, as
well as its internal and independent auditors, at the expense of such partner,
full and complete access to the PVC Partnership's internal and independent
auditors. Each partner will have the right to inspect the books and records and
the physical properties of the PVC Partnership and, at its own expense, to cause
an independent audit thereof.

FINANCIAL AND OTHER INFORMATION
 
     The PVC Partnership will prepare and deliver to the partners the PVC
Partnership financial statements and reports of the PVC Partnership as soon as
reasonably practicable and in any event on or prior to the due dates indicated
in the PVC Partnership Agreement.
 
                 THE COMPOUNDING ASSET CONTRIBUTION AGREEMENTS
 
     The following is a summary of the material provisions of the Asset
Contribution Agreements between Geon, Geon Compounding General Partner, Geon
Compounding Limited Partner, and the Compounding Partnership and between
OxyChem, OCC Compounding Limited Partner, the Compounding Partnership, and Geon
(each a "Compounding Asset Contribution Agreement").
 
     Notwithstanding the assumption of certain liabilities and obligations by
the Compounding Partnership (see " -- Assumed Liabilities" below), Geon or
OxyChem may by law or agreement continue as the primary obligor of certain of
these liabilities. Although the Compounding Partnership will indemnify each of
Geon and OxyChem, and their respective affiliates, for the liabilities assumed
by the Compounding Partnership (see "Indemnification" below), Geon and OxyChem
could be liable with respect to any such liabilities if the Compounding
Partnership is unable to satisfy its indemnification obligations.
 
CONTRIBUTED ASSETS
 
     Geon and OxyChem, on behalf of OCC Compounding Limited Partner, (each a
"Contributor") will contribute to the Compounding Partnership its Compounding
Contributed Assets consisting of all of the assets, rights, and properties used
or held for use in the contemplated operation and conduct of its Compounding
Contributed Business, other than certain excluded assets. In each case, the
Compounding Contributed Business will be the business described herein under
"Businesses and Assets to be Contributed to the Partnerships -- Compounding
Partnership."
 
EXCLUDED ASSETS
 
     The Compounding Contributed Assets contributed to the Compounding
Partnership by a Contributor will not include the following:
 
          (i) any assets of any qualified or non-qualified pension or welfare
     plans or other deferred compensation arrangements maintained by a
     Contributor or any affiliate thereof for employees of such Contributor or
     any affiliate thereof prior to the closing date;
 
          (ii) subject to powder compounding technology agreements (the
     "Compounding Master Intellectual Property Agreements"), any and all of the
     intellectual property of a Contributor or any affiliate thereof to the
     extent not primary used in the normal operation and conduct of, or to the
     extent not applicable to, its Compounding Contributed Business, and any and
     all trademarks of a Contributor;
 
          (iii) all claims and rights against third parties (including insurance
     carriers, indemnitors, suppliers, and service providers), to the extent
     they do not relate to the Compounding Assumed Liabilities (as defined
     below);
 
          (iv) claims held by a Contributor or any affiliate thereof for refunds
     of taxes for time periods ending on or before the closing date, which taxes
     remain the liability of the Contributor or its affiliates under the
     Compounding Asset Contribution Agreements;
 
          (v) all items sold in the ordinary course of business prior to the
     closing date, none of which individually or in the aggregate are material
     to the normal operation and conduct of a Compounding Contributed Business;
 
          (vi) certain tangible assets, intangible assets, real properties,
     contracts, and rights;
 
                                       70
<PAGE>   82
 
          (vii) any real property of a Contributor or any affiliate thereof in
     the vicinity of but not within the legal description of the real property
     being contributed to the Compounding Partnership and any related easements
     or rights-of-way surveyed pursuant to the request or order of the
     Compounding Partnership; and
 
          (viii) the interest of a Contributor and its affiliates in all
     railcars (whether owned or leased) utilized in the operation and conduct of
     its Compounding Contributed Business.
 
ASSUMED LIABILITIES
 
     As of the closing date, the following debts, liabilities, and obligations
of Contributor (collectively, the "Compounding Assumed Liabilities") will be
assumed by the Compounding Partnership in connection with the transfer of the
Compounding Contributed Assets to it, and the Compounding Partnership will agree
to pay, perform, and discharge all such debts, liabilities, and obligations when
due:
 
          (i) all obligations arising on or after the closing date under the
     contracts and leases that are assigned to the Compounding Partnership
     unless and to the extent that such obligation arises out of a violation of
     such contract or lease prior to the closing date;
 
          (ii) all obligations under purchase orders accepted by a Contributor
     in the ordinary course of business of its Contributed Business prior to the
     closing date that are assigned to the Compounding Partnership and that are
     not filled as of the closing date, but only to the extent not filled;
 
          (iii) trade accounts payable;
 
          (iv) all obligations and liabilities, of every kind and nature,
     without limitation, arising out of, in connection with, or related to the
     ownership, operation, or use on or after the closing date of the
     Compounding Contributed Assets or the Compounding Contributed Business,
     except for certain health, safety, and environmental claims that are
     related to the pre-closing liabilities and that arise out of the
     Compounding Partnership's status after the closing date as an owner or
     operator of the Compounding Contributed Assets or the Compounding
     Contributed Business;
 
          (v) except for certain health, safety, and environmental claims,
     Exposure Claims (as defined below) and certain product exposure claims, any
     third party claims that are related to certain pre-closing liabilities that
     are first asserted ten years or more after the closing date;
 
          (vi) certain obligations for indebtedness;
 
          (vii) all liabilities associated with products sold by the Compounding
     Partnership after the closing date regardless of when manufactured;
 
          (viii) any product exposure claims that are first asserted 20 years or
     more after the closing date;
 
          (ix) certain health, safety and environmental claims that are related
     to pre-closing liabilities and that are first asserted ten years or more
     after the closing date;
 
          (x) certain long-term liabilities; and
 
          (xi) any other liability specifically assumed by the Compounding
     Partnership pursuant to the terms of the Compounding Asset Contribution
     Agreements.
 
OTHER AGREEMENTS
 
     Employee Matters. In accordance with the terms of the Master Agreement,
Geon will offer employment to certain employees of OxyChem and its affiliates
whose work is dedicated exclusively to the maintenance or operation of the
OxyChem Compounding Contributed Business or the sale of product produced
therefrom or whose employment is dedicated primarily to the OxyChem Compounding
Contributed Business in a business management or technical position, in each
case on or after the date of the OCC Compounding Asset Contribution Agreement
and prior to the closing date, including employ-
                                       71
<PAGE>   83
 
ees who are, on the closing date, on short-term disability, sick leave, or other
authorized leave of absence and excluding, without limitation, employees of
OxyChem or its affiliates who are on long term disability or who are deceased,
retired, or whose employment terminated prior to the date of the OCC Compounding
Asset Contribution Agreement. Any employee that accepts such an offer is
referred to as a "Hired Employee."
 
     Geon will be responsible for severance costs, if any, with respect to Hired
Employees pursuant to the applicable plan or program of Geon as applicable to
such Hired Employees and in effect as of the termination of employment with Geon
of any such Hired Employee. Any Hired Employee whose employment is terminated by
Geon within six months after the closing date will be entitled to receive a
severance benefit from Geon of not less than benefits substantially comparable
to those provided under the severance plan of OxyChem in effect as if the
closing date to the extent that such benefits would have been payable under such
severance plan.
 
     OxyChem will hold Geon and its affiliates harmless for any past, current,
or future liabilities associated with or relating to the employment or
termination of employment of OxyChem's employees who do not become Hired
Employees and for any past, current, or future liabilities associated with or
relating to the employment or termination of employment of any person with
respect to employment or termination of employment with OxyChem or OxyChem's
affiliates.
 
     Support Services. For two years from the date of the Compounding Asset
Contribution Agreements, the Compounding Partnership will have the right to
purchase services from the businesses being retained by the Contributors at full
cost and otherwise on arm's-length terms, in all cases where it is reasonable
for such retained businesses to provide the services. In no event will the
services be in excess of the quantity of, or in kind other than, the services
provided to the Compounding Contributed Businesses prior to the closing date.
Similarly, for a period of two years from the date of the Compounding Asset
Contribution Agreements, the businesses retained by the Contributors will have
the right to purchase services from the Compounding Partnership at full cost and
otherwise on arm's-length terms in all cases where it is reasonable for the
Compounding Partnership to provide the services.
 
INDEMNIFICATION
 
     Subject to the terms described below, each Contributor will agree, to the
fullest extent permitted by applicable law, to indemnify, defend, and hold
harmless the Compounding Partnership and its affiliates and their respective
officers, directors, and employees from, against, and in respect of any
liabilities 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 the Contributor or any of its affiliates subject to certain
     materiality qualifications in the Compounding Asset Contribution
     Agreements, certain Assignment and Assumption Agreements, the Compounding
     Master Intellectual Property Agreement, or the Master Agreement; provided,
     however, that any liability arising out of, in connection with, or relating
     to any breach of warranties in any Assignment and Assumption Agreement that
     is not a breach of warranties under the Compounding Asset Contribution
     Agreements will not be indemnifiable pursuant to the Compounding Asset
     Contribution Agreement;
 
          (ii) any failure of the Contributor or any of its affiliates to
     perform any of its covenants or obligations contained in the Compounding
     Asset Contribution Agreements, certain Assignment and Assumption
     Agreements, the Compounding Master Intellectual Property Agreements, or the
     Master Agreement;
 
          (iii) excluded assets;
 
          (iv) any exposure of any person to PVC, VCM, or chemical substances in
     connection with the Compounding Contributed Business, to the extent such
     liability is attributable to the period prior to the closing date
     ("Exposure Claims");
 
                                       72
<PAGE>   84
 
          (v) any product exposure claim that is not a Compounding Assumed
     Liability;
 
          (vi) certain health, safety and environmental claims that are related
     to pre-closing liabilities and that are not Compounding Assumed
     Liabilities;
 
          (vii) any third party claim (other than Exposure Claims, product
     exposure claims, and certain health, safety, and environmental claims) that
     is related to a pre-closing liability and that is not a Compounding Assumed
     Liability;
 
          (viii) with respect to Geon only, any obligation (A) for the payment
     of severance benefits to employees of a Contributor or any of its
     affiliates, except as otherwise agreed to by the parties or (B)
     attributable to a Contributor's or any of its affiliate's employment of any
     employee, agent, or independent contractor prior to the closing date and
     with respect to OxyChem only, for employee liabilities assumed by OxyChem
     and its affiliates pursuant to the OCC Compounding Asset Contribution
     Agreement; or
 
          (ix) any taxes of the Contributor and, in the case of Geon, Geon
     Compounding General Partner or Geon Compounding Limited Partner, and, in
     the case of OxyChem, OCC Compounding Limited Partner, for any taxable
     period or portion thereof ending before the closing date or arising from
     any of the transactions contemplated by the Compounding Asset Contribution
     Agreements.
 
     OxyChem will also agree to the fullest extent permitted by applicable law,
to indemnify, defend, and hold harmless Geon, its affiliates and their
respective officers, directors, and employees from, against, and in respect of
any liabilities incurred or suffered by Geon or any of its affiliates, arising
out of, in connection with, or relating to clauses (i), (ii), and (viii) listed
above.
 
     The indemnification obligations of each Contributor under their respective
Compounding Asset Contribution Agreements described in clause (i) above are
subject to the following limitations: (a) each Contributor, in the aggregate,
will not have any indemnification obligation under clause (i) above for any
individual liability unless the amount of such liability exceeds $100,000 (the
"Individual Basket"), and until the total of all liabilities under said clause
(i) equals an aggregate deductible of $500,000 (the "Deductible"); and provided
further that the parties agree the amount of liability for which indemnification
may be sought for breach of any representation and warranty under clause (i)
will be calculated taking into account the Individual Basket and Deductible
without regard to any qualification or exception regarding materiality or
material adverse effect qualification contained in such representation and
warranty, and (b) if a Contributor is indemnifying against a particular
liability under two or more of clauses (i) through (ix) above, the Compounding
Partnership and the other indemnitees will have the right to select the clause
or clauses under which they seek indemnification, provided that the aggregate
indemnification will in no event exceed the amount of the particular liability.
 
     Subject to the other indemnification provisions of the Compounding Asset
Contribution Agreements, the Compounding Partnership also will indemnify, to the
fullest extent permitted by law, each 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 them arising out of or relating
to: (i) any misrepresentation in or breach of the representations and warranties
of the Compounding Partnership or the failure of the Compounding Partnership to
perform any of its covenants or obligations contained in the Compounding Asset
Contribution Agreements, certain Assignment and Assumption Agreements, the
Compounding Master Intellectual Property Agreements, or the Master Agreement;
(ii) Compounding Assumed Liabilities; or (iii) any health, safety, or
environmental claim to the extent arising out of the Compounding Partnership's
exacerbation or acceleration of such health, safety, or environmental claim.
 
     The rights provided to the Compounding Partnership and the Contributors
will be the sole remedy for such party for breach of representation and warranty
by or covenant or obligation of the other party under the Compounding Asset
Contribution Agreements, certain Assignment and Assumption Agreements, the
Compounding Master Intellectual Property Agreements, and the Master Agreement or
arising out of, in connection with, or related in any way to the subject matter
of the Compounding Asset Contribution Agreements.
                                       73
<PAGE>   85
 
PAYMENT OF CERTAIN EXPENSES AND TAXES
 
     Subject to the following provisions, each Contributor will be responsible
for all taxes attributable to that Contributor's or its affiliate's ownership or
use of the Compounding Contributed Assets or the operation of its Compounding
Contributed Business prior to the closing date, and the Compounding Partnership
will be responsible for all taxes attributable to the Compounding Partnership's
ownership, use, or transfer of the Compounding Contributed Assets or operation
of the Compounding Contributed Businesses after the closing date. All sales,
use, value added, excise, transfer, land transfer or other similar taxes
incurred in connection with the transfer of the Compounding Contributed Assets
to the Compounding Partnership will be borne solely by the Contributor. All real
property taxes, personal property taxes, ad valorem taxes, and other similar
taxes (or payments in lieu of such taxes) assessed on any of the Compounding
Contributed Businesses or Compounding Contributed Assets in the tax period in
which the closing date occurs will be prorated between the Compounding
Partnership and the appropriate Contributor as of the closing date. The
Compounding Partnership will pay any title or recordation fees in connection
with the transfer of the Compounding Contributed Assets. The Compounding
Partnership will also pay for any surveys of the fee interests and any related
easements or rights-of-way that are requested or ordered by the Compounding
Partnership.
 
                     THE COMPOUNDING PARTNERSHIP AGREEMENT
 
     The following is a summary of the material provisions of the Compounding
Partnership Agreement.
 
GENERAL
 
     In connection with the formation of the Compounding Partnership, Geon
Compounding General Partner, Geon Compounding Limited Partner and OCC
Compounding Limited Partner will enter into the Compounding Partnership
Agreement which will govern the management and operations of the Compounding
Partnership. The Compounding Partnership will continue in existence until its
dissolution in accordance with the terms of the Compounding Partnership
Agreement. See " -- Dissolution and Termination." The general partner of the
Compounding Partnership will be Geon Compounding General Partner, a direct,
wholly-owned subsidiary of Geon.
 
GOVERNANCE
 
     The Compounding Partnership Governance Committee will manage and control
the business, property, and affairs of the Compounding Partnership, including
the determination and implementation of the Compounding Partnership's strategic
direction. The Compounding Partners will exercise their authority to manage and
control the Compounding Partnership only through the Compounding Partnership
Governance Committee. The Compounding Partnership Governance Committee will
consist of four representatives, two of whom will be designated by Geon
Compounding General Partner and two of whom will be designated by OCC
Compounding Limited Partner.
 
     In general, the approval of one representative acting for Geon Compounding
General Partner will be sufficient for the Compounding Partnership Governance
Committee to take any action. However, the Compounding Partnership Governance
Committee will not be permitted to take certain actions unless such actions are
approved by one representative of OCC Compounding Limited Partner and one
representative of Geon Compounding General Partner, as described below. See
" -- Unanimous Voting Requirements." This means, in effect, that Geon's
representatives will control the Compounding Partnership Governance Committee
(and, as a result, the Compounding Partnership) except where the approval of one
of OxyChem's representatives is required.
 
UNANIMOUS VOTING REQUIREMENTS
 
     Unless approved by one representative of each of Geon Compounding General
Partner and OCC Compounding Limited Partner, the Compounding Partnership
Governance Committee may not directly
 
                                       74
<PAGE>   86
 
or indirectly take (or commit to take), and none of the Compounding Partnership,
any subsidiary thereof or any person acting in the name of or on behalf of any
of them, directly or indirectly, may take or commit to take any of the following
actions (whether in a single transaction or a series of related transactions):
 
          (i) to cause the Compounding Partnership, directly or indirectly, to
     engage, participate, or invest in any business outside the scope of its
     business as described in the Compounding Partnership Agreement;
 
          (ii) to approve any strategic plan, as well as any amendments or

     Partnership Agreement;
 
          (iv) to authorize any acquisition of assets outside the ordinary
     course of business exceeding $2 million that is not contemplated in an
     approved strategic plan, or to authorize any capital expenditure or
     investment exceeding any amount contemplated in an approved strategic plan
     by more than $2 million;
 
   
          (v) to require capital contributions to the Compounding Partnership
     materially in excess of contributions contemplated by the Compounding Asset
     Contribution Agreements or an approved strategic plan or amounts necessary
     to achieve or maintain compliance with the law;
    
 
   
          (vi) to cause the Compounding Partnership or any subsidiary of the
     Compounding Partnership to issue, sell, redeem, or acquire any units or

     except as provided in the Compounding Partnership Agreement with regard to
     capital contributions;
    
 
   
          (vii) except as provided in connection with a dissolution of the
     Compounding Partnership, to make Compounding Partnership distributions that
     are materially in excess of amounts contemplated in an approved strategic
     plan;
    
 
          (viii) to initiate or settle any litigation or governmental

          (ix) to change the Compounding Partnership's method of accounting or
     to make certain tax elections;

          (xi) to merge, consolidate, or convert the Compounding Partnership or
     any subsidiary thereof with or into any other entity (other than a
     wholly-owned subsidiary of the Compounding Partnership);
 
          (xii) to file a petition in bankruptcy or seek any reorganization,
     liquidation, or similar relief on behalf of the Compounding Partnership or
     any subsidiary of the Compounding Partnership; or to consent to the filing
     of a petition in bankruptcy against the Compounding Partnership or any
     subsidiary of the Compounding Partnership; or to consent to the appointment
     of a receiver, custodian, liquidator, or trustee for the Compounding
     Partnership or any subsidiary thereof or for all or any substantial portion
     of their respective property;
 
          (xiii) except in connection with the dissolution of the Compounding
     Partnership, to enter into an indemnification agreement whereby the
     Compounding Partnership agrees (A) to indemnify a partner, (B) to an
     indemnification outside of the ordinary course of business or (C) to an
     indemnification for any item that could cause obligations of the
     Compounding Partnership in excess of $1 million;
 
          (xiv) to approve certain loans to Geon or OxyChem as described in the
     Compounding Parent Agreement; or
                                       75
<PAGE>   87
 
          (xv) to revoke the requirement that the Compounding Partnership cause
     an audit to be conducted annually.
 
     Although unanimous approval by all four members of the Compounding
Partnership Governance Committee is never required, Geon and OxyChem have
referred to the requirement described above as "unanimous voting requirements"
because one representative of each of Geon Compounding General Partner and OCC
Compounding Limited Partner must agree on any action in respect of such
enumerated matters.
 
TRANSACTIONS WITH AFFILIATES
 
     Upon receipt of any required approval by the Compounding Partnership
Governance Committee, all contracts and transactions between the Compounding
Partnership and a partner or its affiliates and the Related Agreements will 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 the
Compounding Partnership Agreement or the existence of the Compounding
Partnership.
 
STRATEGIC PLANS, ANNUAL BUDGETS, AND EXPENSES
 
     The Compounding Partnership will be managed in accordance with a three-year
strategic plan that will be updated annually under the direction of Geon
Compounding General Partner and presented for approval by the Compounding
Partnership Governance Committee no later than 45 days prior to the start of the
first fiscal year covered by the updated plan. The strategic plan must be
approved each year by at least one representative of each of Geon Compounding
General Partner and OCC Compounding Limited Partner. The strategic plan will
establish the strategic direction of the Compounding 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. The strategic plan also will establish the Compounding
Partnership's policy regarding the timing and amount of any distributions to the
partners. However, the partners contemplate that the strategic plan will provide
that, except for debt redemption or prepayment goals contained therein, the
amount of cash available for distribution as of the end of each month will be
distributed to the partners pro rata. Except for entering into the Related
Agreements, the Compounding Partnership will not, on other than an arm's-length
basis, enter into, or waive any material rights under, any agreement between the
Compounding Partnership and a partner or its affiliates unless the taking of
such action is specifically contemplated by an approved strategic plan.
 
     In addition, Geon Compounding General Partner will prepare an annual budget
for each fiscal year. Each annual budget will include an operating budget and
capital expenditure budget, provided that each annual budget will be consistent
with the information for such fiscal year included in the strategic plan most
recently approved by the partners. Unless otherwise provided in the most
recently approved strategic plan, each annual budget will utilize a format and
provide a level of detail consistent with the Compounding Partnership annual
budget for the 1998 fiscal year.
 
     If, after the first anniversary of the date of the Compounding Partnership
Agreement, the Compounding Partnership Governance Committee does not agree on a
matter requiring approval of one representative of each of Geon Compounding
General Partner and OCC Compounding Limited Partner, then Geon Compounding
General Partner and OCC Compounding Limited Partner will submit their
disagreements to non-binding mediation by a Mediator who will be mutually agreed
upon by Geon Compounding General Partner and OCC Compounding Limited Partner (or
by certain third parties if Geon Compounding General Partner and OCC Compounding
Limited Partner cannot agree). Within 20 days of selection of the Mediator, two
persons having decision-making authority on behalf of each of Geon Compounding
General Partner and OCC Compounding Limited Partner will meet with the Mediator
and agree upon procedures and a schedule for attempting to resolve the
differences between Geon
 
                                       76
<PAGE>   88
 
Compounding General Partner and OCC Compounding Limited Partner. They will
continue to meet thereafter on a regular basis until (i) agreement is reached by
Geon Compounding General Partner and OCC Compounding Limited Partner (acting
through their representatives) on such matter or (ii) at least 90 days have
elapsed since such first meeting among Geon Compounding General Partner, OCC
Compounding Limited Partner and the Mediator, and Geon Compounding General
Partner or OCC Compounding Limited Partner determines and notifies the other and
the Mediator in writing that no agreement resolving the dispute is likely to be
reached (a "Deadlock Notice"). Following any such Deadlock Notice, either Geon
Compounding General Partner or OCC Compounding Limited Partner may elect to
dissolve the Compounding Partnership. See " -- Dissolution and Termination" and
"Geon's Right to Acquire OCC Limited Partner's Units." In no event will the OCC
Compounding General Partner or Geon Compounding Limited Partner have the right
to commence the above described procedures until after the first anniversary of
the date of the Compounding Partnership Agreement.
 
     Generally, all Compounding Partnership expenses (both operating and capital
expenses), regardless of whether included in any strategic plan or annual
budget, will be funded from operating cash flows or authorized borrowings under
available lines of credit, unless otherwise agreed by the Compounding
Partnership Governance Committee or, in certain circumstances, determined by
Geon Compounding General Partner. See " -- Capital Contributions."
 
DISTRIBUTION OF AVAILABLE NET OPERATING CASH
 
     Distributions to the partners of cash or property arising from a
liquidation of the Compounding Partnership will be made in accordance with the
capital account balances of the partners.
 
     Any amount otherwise distributable to a partner as described above will be
applied by the Compounding Partnership to satisfy any of the following
obligations that are owed by such partner or its affiliate to the Compounding
Partnership and that are not paid when due: (i) any interest or principal due on
any indebtedness for borrowed money of such partner or any affiliate of such
partner to the Compounding Partnership; (ii) any payment pursuant to a
Compounding Asset Contribution Agreement that has been finally determined to be
due; and (iii) any capital contribution required pursuant to the Compounding
Partnership Agreement (other than pursuant to a Compounding Asset Contribution
Agreement).
 
CAPITAL CONTRIBUTIONS
 
     Upon the formation of the Compounding Partnership, the partners will
contribute to the Compounding Partnership the Compounding Contributed Assets,
subject to the assumption by the Compounding Partnership of the Compounding
Assumed Liabilities, in exchange for an aggregate of 100 units. Geon and OxyChem
intend that the contribution of assets, subject to liabilities, will qualify as
a tax-free contribution under Section 721 of the Code in which no partner will
recognize gain or loss. The partners will agree that the Compounding Partnership
will so file its tax return, and each partner will agree to file its tax return
on the same basis and to maintain such position consistently at all times
thereafter.
 
     Subject to the requirement that one representative of each of Geon
Compounding General Partner and OCC Compounding Limited Partner approve certain
capital contributions, the Compounding Partnership Governance Committee, on
behalf of the Compounding Partnership, may issue a written notice to the
partners calling for an additional capital contribution to the Compounding
Partnership. The aggregate amount of such additional contribution will be
apportioned among the partners pro rata. In addition, subject to the limitation
that the approval of one representatives of each of Geon Compounding General
Partner and OCC Compounding Limited Partner is required for certain capital
contributions, Geon Compounding General Partner may also issue a funding notice
to the Compounding Limited Partners, to the extent that it determines at any
time that funds are needed to fund the operations of the Compounding
Partnership.
 
                                       77
<PAGE>   89
 
DESCRIPTION OF PARTNERS
 
     Except as expressly set forth in the Compounding Partnership Agreement,
each of Geon Compounding General Partner and OCC Compounding Limited Partner
will agree to exercise its authority to manage and control the Compounding
Partnership only through action of the Compounding Partnership Governance
Committee. Neither Geon Compounding General Partner nor OCC Compounding Limited
Partner will have the authority, and each will agree 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 Compounding
Partnership or any other partner, (ii) to execute any documents on behalf of, or
otherwise bind, or purport or attempt to bind, the Compounding Partnership, or
(iii) to otherwise transact any business in the name of the Compounding
Partnership, in each case except pursuant to action of the Compounding
Partnership Governance Committee.
 
     Geon Compounding General Partner and Geon Compounding Limited Partner will
be Delaware corporations which are direct, wholly-owned subsidiaries of Geon.
Neither Geon Compounding General Partner nor Geon Compounding Limited Partner
will have any business or assets except for their ownership of units in the
Compounding Partnership. In the Compounding Partnership Agreement, Geon
Compounding General Partner and Geon Compounding Limited Partner will each agree
that its business will be restricted solely to the holding of its units in the
Compounding Partnership and the doing of things necessary or appropriate in
connection therewith and that it will not own any assets, incur any liabilities,
or engage, participate, or invest in any business outside the scope of such
business.
 
     OCC Compounding Limited Partner will be a Delaware limited liability
company and an indirect, wholly-owned affiliate of OxyChem. OCC Compounding
Limited Partner will have no business or assets except for its ownership of
limited partner units in the Compounding Partnership. In the Compounding
Partnership Agreement, OCC Compounding Limited Partner will agree that its
business will be restricted solely to the holding of its units in the
Compounding Partnership and the doing of things necessary or appropriate in
connection therewith and that it will not own any assets, incur any liabilities,
or engage, participate, or invest in any business outside the scope of such
business.
 
INDEMNIFICATION
 
     The Compounding Partnership will agree, 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 person may sustain, incur, or assume
as a result of, or relative to, any third party claim arising out of or in
connection with the business, property, or affairs of the Compounding
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 the Compounding Partnership Agreement or any Related Agreement. This
indemnification obligation is not intended to, nor will it, affect or take
precedence over the indemnity provisions contained in any Related Agreement.
 
TRANSFERS AND PLEDGES
 
     Without the consent of the Compounding Partnership Governance Committee, no
partner will transfer less than all of its units in the Compounding Partnership,
and no partner will transfer its units for consideration other than cash. If any
Compounding Limited Partner and, in the case of Geon Compounding Limited
Partner, its affiliated Geon Compounding General Partner, desire to transfer all
of their units (together, the "Selling Partners"), they must give written notice
(the "Initial Notice") to the Compounding Partnership and the other partners
(the "Offeree Partners") stating the Selling Partners desire to transfer their
units and stating the cash purchase price and all other terms on which they are
willing to sell their units (the "Offer Terms"). Delivery of an Initial Notice
will constitute the irrevocable offer of the Selling Partners to sell their
units to the Offeree Partners. The Offeree Partners will have the option,
exercisable by delivering written notice (the "Acceptance Notice") of such
exercise to the Selling
 
                                       78
<PAGE>   90
 
Partners within 60 days of the date of Initial Notice, to elect to purchase all
of the units of the Selling Partners on the Offer Terms described in the Initial
Notice. The Acceptance Notice will 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, subject to extension in certain circumstances. The purchase
price for the Selling Partners' units will be paid in immediately available
funds delivered at the closing.
 
     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 will have a further 180 days during which they may, subject to
certain conditions described below, consummate the sale of their units to a
third party purchaser at a purchase price and on such other terms that are not
substantially more favorable to the 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 180-day period, the Initial Notice will be
deemed to have expired and a new notice and offer will be required before the
Selling Partners may make any transfer of their units.
 
     Notwithstanding the above, without the need for the consent of any person,
any partner may transfer its units to any 80%-owned affiliate of such partner.
In addition, Geon Compounding Limited Partner may, at its option, at any time
and without the need for the consent of any person, transfer up to 99% of its
limited partner units to Geon Compounding General Partner, whereupon such
limited partner units will, without any further action, become general partner
units. Promptly following any such transfer of limited partner units, each
partner will take such actions and execute such instruments or documents
(including amendments to the Partnership Agreement or supplemental agreements
thereto) as may be reasonably necessary to ensure that Geon Compounding General
Partner and Geon Compounding Limited Partner will, taken as a whole and
following such transfer, maintain all of its rights under the Compounding
Partnership Agreement as in effect immediately prior to such transfer (including
the portion of any Compounding Partnership cash distributable to such partners).
 
DEFAULT
 
     Each of the following events will constitute a "Default" and create the
rights provided for below in favor of the Compounding Partnership and the
partners not in default ("Non-Defaulting Partners") against the partners in
default ("Defaulting Partners"): (i) the failure by a partner to make any
contribution to the Compounding Partnership as required pursuant to the
Compounding Partnership Agreement (other than pursuant to a Compounding Asset
Contribution Agreements), 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 the Compounding Partnership Agreement), or (iii) the bankruptcy of a
partner or its parent. The day upon which a 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) is the "Default Date."
 
     Following a default, in addition to any other remedies they may have, the
Non-Defaulting Partners in their sole discretion may elect to pursue the
following remedies: (i) 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 of the units of the Defaulting Partners; 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 will have an additional 30 days following such decision
to elect an alternative remedy, and (ii) 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 clause (i) 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 Compounding Partnership and thereby cause
the Compounding Partnership to dissolve. See " -- Dissolution and Termination."
 
     Upon any election to purchase a Defaulting Partners' units following a
Default, the purchase price that the Non-Defaulting Partners will pay to the
Defaulting Partners for their units will be an amount
 
                                       79
<PAGE>   91
 
equal to (i) the amount that the Defaulting Partners would receive in a
liquidation (assuming that any sale in connection with the dissolution of the
Compounding Partnership was 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. 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 by delivering notice in writing
to the Defaulting Partners. The Non-Defaulting Partners will have 10 days from
the final determination of fair market value to elect to purchase the units of
the Defaulting Partners by delivering notice of such election in writing, and
the purchase will be consummated within 60 days from the date such notice is
delivered, subject to extension in certain circumstances. 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
other partner.
 
     If the Non-Defaulting Partners elect to dissolve the Compounding
Partnership as a result of a Default, any amount payable to the Defaulting
Partners in the resulting liquidation will be reduced by, without duplication,
any unrecovered damages incurred by the Compounding Partnership in connection
with the Default.
 
     Commencing on the Default Date and (i) prior to the Non-Defaulting
Partners' collection of damages through the exercise of their legal remedies or
otherwise, or (ii) while the Non-Defaulting Partners are pursuing their remedies
as described above, the representatives of the Defaulting Partner will not have
any voting or decisional rights with respect to matters requiring Compounding
Partnership Governance Committee action, and such matters will be determined
solely by the representatives of the Non-Defaulting Partner. However, the
foregoing loss of voting and decisional rights will not occur as a result of a
default caused solely by the bankruptcy of a partner, OxyChem, or Geon and, in
the case of a default caused by the failure of a partner to make any
contribution to the Compounding Partnership pursuant to the Compounding
Partnership Agreement, will not apply to the unanimous voting and decisional
rights in respect of changes in the scope of the Compounding Partnership's
business, the issuance, sale, redemption, or acquisition of units or other
equity securities by the Compounding Partnership or any subsidiary, changes in
respect of accounting methods or tax elections, or with respect to mergers,
consolidations, or conversions of the Compounding Partnership or a subsidiary
thereof. See " -- Unanimous Voting Requirements."
 
DISSOLUTION AND TERMINATION
 
     As long as OCC Compounding Limited Partner is willing then to convert its
units to general partner units and thereafter serve as the Compounding General
Partner (who is hereby authorized in such event to convert its units and to
conduct the business of the Compounding Partnership without dissolution), the
withdrawal, retirement, resignation, dissolution, or bankruptcy of Geon
Compounding General Partner will not dissolve the Compounding Partnership, but
rather will be a Default. See " -- Default." The Compounding Partnership will be
dissolved, however, upon the happening of any one of the following events: (i)
the written determination of both Geon Compounding General Partner and OCC
Compounding Limited Partner to dissolve the Compounding Partnership, (ii) the
entry of a judicial decree of dissolution, (iii) any other act or event which
results in the dissolution of a limited partnership under the Delaware Revised
Uniform Limited Partnership Act (except as provided in the first sentence of
this paragraph); (iv) the election of the Non-Defaulting Partners to effect a
dissolution of the Compounding Partnership (see " -- Defaults"); or (v) after
the delivery of a Deadlock Notice by either Geon Compounding General Partner or
OCC Compounding Limited Partner (see " -- Strategic Plans, Annual Budgets, and
Expenses"), the written determination by either Geon Compounding General Partner
or OCC Compounding Limited Partner to dissolve the Compounding Partnership.
 
     If the Compounding Partnership dissolves, it will commence winding-up
pursuant to the appropriate provisions of the Delaware Revised Uniform Limited
Partnership Act and the procedures set forth below. Notwithstanding the
dissolution of the Compounding Partnership, prior to the termination of the
Compounding Partnership, the business of the Compounding Partnership and the
affairs of the partners, as such, will continue to be governed by the
Compounding Partnership Agreement. The winding up of the
                                       80
<PAGE>   92
 
Compounding Partnership will be conducted under the direction of the Compounding
Partnership Governance Committee. However, (i) if Geon Compounding General
Partner and Geon Compounding Limited Partner are the Defaulting Partners and OCC
Compounding Limited Partner is a Non-Defaulting Partner, such winding-up will be
conducted under the direction of OCC Compounding Limited Partner, and (ii) if
the dissolution is caused by entry of a decree of judicial dissolution, the
winding up will be carried out in accordance with such decree. The person or
committee conducting the winding-up of the Compounding Partnership (the
"Compounding Liquidator") will cause the Compounding Partnership to attempt to
sell all property of the Compounding Partnership. Upon dissolution of the
Compounding Partnership, the Compounding Liquidator will determine the time,
manner, and terms of any sale or sales of Compounding 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.
 
     In the case of a dissolution and winding-up of the Compounding Partnership,
the Compounding Partnership's assets will be applied first to the satisfaction
of the liabilities of the Compounding 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 Compounding 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 Compounding Liquidator
may deem advisable, such reserves will be distributed to the partners or their
assigns in the manner set forth below. The assets will then be applied, after
all allocations of profits or losses and other certain items specified in the
Compounding Partnership Agreement, to the partners in accordance with the
balances in their capital accounts. Notwithstanding the foregoing, if any
partner is indebted to the Compounding 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 Compounding
Partnership will retain such partner's distributive share of the Compounding
Partnership property and apply such sums to the liquidation of such indebtedness
and the cost of operation of such Compounding Partnership property during the
period of such liquidation.
 
GEON'S RIGHT TO ACQUIRE OCC LIMITED PARTNER'S UNITS
 
     Except for a dissolution of the Compounding Partnership where Geon
Compounding General Partner and Geon Compounding Limited Partner are the
Defaulting Partners, upon the occurrence of any event giving rise to the
dissolution of the Compounding Partnership, in lieu of the sale of Compounding
Partnership properties and the application of the Compounding Partnership
assets, Geon Compounding General Partner or its designee will have the right,
exercisable by written notice to OCC Compounding Limited Partner, given within
15 days after the occurrence of such event, to acquire all of the units of OCC
Compounding Limited Partner, at the price and on the terms and conditions
specified in the Compounding Partnership Agreement that would apply to an
exercise by OCC Compounding Limited Partner of its put right thereunder.
 
OCC LIMITED PARTNER'S PUT RIGHT
 
     OCC Compounding Limited Partner will have the right at any time to provide
a notice to Geon Compounding General Partnership stating that OCC Compounding
Limited Partner thereby elects to cause Geon Compounding General Partner or its
designee to acquire all of OCC Compounding Limited Partner's units. The purchase
price for the units will be equal to the selling Partner's pro rata portion of
5.75 times the sum of the Compounding Partnership's net income from operations
before any extraordinary items, plus certain expenses or charges to the extent
deducted from net income, ("EBITDA") as of and for the 12-month period ending on
the last day of the calendar month immediately preceding the date of such
calculation, minus OxyChem's pro rata portion of any indebtedness of the
Compounding Partnership.

LIMITATION OF FIDUCIARY DUTIES; NON-COMPETITION
 
     The liability of Geon Compounding General Partner (including any liability
of its affiliates or its and their respective officers, directors, agents, and
employees) or of any Compounding Limited Partner (including any liability of its
affiliates or its and their respective officers, agents, directors and
employees), either to the Compounding Partnership or to any other partner, for
any act or omission by such partner in its capacity as a partner of the
Compounding Partnership that is imposed by such partner's status as a "general
partner" or "limited partner" (as such terms are used in the Delaware Revised
Uniform Limited Partnership Act) of a limited partnership will be eliminated,
waived, and limited to the fullest extent permitted by law; provided, however,
that Geon Compounding General Partner and OCC Compounding Limited Partner will
at all times owe to the other a fiduciary duty in observing the requirement that
one representative of each of Geon Compounding General Partner and OCC
Compounding Limited Partner on the Compound Partnership Governance Committee
will be required to give their approval before the Compounding Partnership may
undertake certain actions requiring unanimous approval. See " -- Unanimous
Voting Requirements." Geon Compounding General Partner and OCC Compounding
Limited Partner will at all times owe to the other a duty to act in good faith
with respect to all matters involving the Compounding Partnership.
 
     Except as described below, each partner's affiliates will be free to engage
in or possess an interest in any other business of any type, including any
business in direct competition with the Compounding Partnership, and to avail
itself of any business opportunity available to it without having to offer the
Compounding Partnership or any partner the opportunity to participate in such
business. If a partner's affiliate desires to initiate or pursue an opportunity
to undertake, engage in, acquire, or invest in a business, activity, or
operation within the scope of the business of the Compounding Partnership (a
"Compounding Related Business") by investing in or acquiring a person whose
business is a Compounding Related Business, acquiring assets of a Compounding
Related Business or otherwise engaging in or undertaking a Compounding Related
Business (a "Compounding Business Opportunity"), such affiliate (such affiliate,
together with its affiliates being called the "Proposing Person") will offer the
Compounding Partnership the Compounding Business Opportunity.
 
     When a Proposing Person offers a Compounding Business Opportunity to the
Compounding Partnership, the Compounding Partnership will elect to do one of the
following within a reasonably prompt period: (i) acquire or undertake the
Compounding Business Opportunity for the benefit of the Compounding Partnership
as a whole, at the cost, expense, and benefit of the Compounding Partnership, or
(ii) permit the Proposing Person to acquire or undertake the Compounding
Business Opportunity for its own benefit and account without any duty to the
Compounding Partnership or the other partners with respect thereto. However, if
the Compounding Business Opportunity is in direct competition with the then
existing business of the Compounding Partnership (a "Competing Opportunity"),
then the Proposing Person and the Compounding Partnership will, if either so
elects, promptly seek to negotiate and implement an arrangement whereby the
Compounding 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 Compounding 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
Compounding Partnership. If the Compounding Partnership and the Proposing Person
do not reach agreement as to such arrangement, the Proposing Person may acquire
or undertake the Competing Opportunity for its own benefit and account without
any duty to the Compounding Partnership or the other partners with respect
thereto.
 
     In addition, if the Compounding Business Opportunity constitutes less than
25% (based on annual revenues of the business to be acquired or invested in for
the most recently competed fiscal year) of an acquisition of or investment in
assets, activities, operations, or businesses that is not otherwise a
Compounding Related Business, then a Proposing Person may acquire or invest in
such Compounding
                                       82
<PAGE>   94
 
Business Opportunity without first offering it to the Compounding Partnership;
provided, that, after completion of the acquisition or investment thereof, such
Proposing Person must offer the Compounding Business Opportunity to the
Compounding Partnership as described above. If the Compounding Partnership
elects to pursue such Compounding Business Opportunity, it will be acquired by
the Compounding Partnership its fair market value as mutually agreed or finally
determined as of the date of such acquisition.
 
     If (i) the Compounding Partnership is presented with an opportunity to
acquire or undertake a Compounding Business Opportunity that it determines not
to acquire or undertake and (ii) the representatives of either Geon Compounding
General Partner or OCC Compounding Limited Partner, but not the other, desired
that Compounding Partnership acquire or undertake such Compounding Business
Opportunity, then the Compounding Partnership will permit such first partner's
affiliates to acquire or undertake such Compounding Business Opportunity, and
such Compounding Business Opportunity will be treated in the same manner as if
such partner's affiliates were a Proposing Person with respect to such
Compounding Business Opportunity.
 
FINANCIAL AND ACCOUNTING MATTERS; AUDITS
 
     The fiscal year of the Compounding Partnership will begin on January 1 and
end on December 31. For financial reporting purposes, the Compounding
Partnership will adopt a standard set of accounting policies and will maintain
separate books of account, all in accordance with GAAP. The initial independent
auditors of the Compounding Partnership will be Ernst & Young LLP, unless and
until changed by the Compounding Partnership Governance Committee or unless and
until the Compounding Partnership is no longer required by the Compounding
Partnership Agreement to cause an independent audit to be conducted. The
Compounding Partnership will report its operations for tax purposes utilizing
the accrual method of accounting. The Compounding Partnership will give each
partner, as well as its internal and independent auditors, at the expense of
such partner, full and complete access to the Compounding Partnership's internal
and independent auditors. Each partner will have the right to inspect the books
and records and the physical properties of the Compounding Partnership and, at
its own expense, to cause an independent audit thereof at any time.
 
FINANCIAL AND OTHER INFORMATION
 
     The Compounding Partnership will prepare and deliver to the partners
certain Compounding Partnership financial statements and reports of the
Compounding Partnership as soon as reasonably practicable and in any event on or
prior to the due dates indicated in the Compounding Partnership Agreement.
 
                             THE PARENT AGREEMENTS
 
     The following is a summary of the material provisions of the Parent
Agreement relating to the PVC Partnership and the Parent Agreement relating to
the Compounding Partnership. The term "Partner Subs" refers to Geon PVC Limited
Partner or Geon Compounding General Partner and Geon Compounding Limited Partner
and OCC PVC General Partner and OCC PVC Limited Partner or OCC Compounding
Limited Partner, as the context may require.
 
RESTRICTIONS ON TRANSFER AND PLEDGE OF PARTNER SUB STOCK
 
     Geon and OxyChem will agree that, except as otherwise described below or
with the written consent of the other, which consent may be granted or withheld
in such other party'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
                                       83
<PAGE>   95
 
equity interests) of its Partner Subs (collectively, the "Partner Sub Stock").
Any attempt by Geon or OxyChem to Transfer or Pledge all or a portion of its
Partner Sub Stock in violation of the Parent Agreements will be void and will
not be effective to Transfer such Partner Sub Stock or any portion thereof.
 
     Geon or OxyChem, as the case may be, 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, or share exchange, or change of control of
such party or (B) a sale or other disposition of such party of assets including
the Partner Sub Stock where such Partner Sub Stock constitutes less than fifty
percent (50%) of the book value of the aggregate assets to be sold or disposed
of, as reflected on such party's most recent audited consolidated (or combined)
financial statements; (ii) to an eighty percent (80%) owned affiliate of such
party; or (iii) to the stockholders, in the case of Geon, or to OPC, in the case
of OxyChem.
 
     Geon or OxyChem may Pledge all (but not less than all) of its Partner Sub
Stock in connection with a loan to such party, provided that (i) the loan to
such party has been approved by the PVC Partnership or the Compounding
Partnership, as the case may be, and (ii) the Pledge will be evidence by an
instrument, reasonably satisfactory to the PVC Partnership or Compounding
Partnership, as the case may be. In such instrument, the lender receiving such
Pledge will agree that in the event such lender obtains a right of foreclosure
on such party's Partner Sub Stock, such lender will foreclose on the Partner Sub
Stock of each of Geon's or OxyChem's, as the case may be, Partner Subs
proportionately so that such lender will in all events hold portions of Partner
Sub Stock of the general partner and limited partner of Geon or OxyChem, as the
case may be, proportionate to such parent's holdings in the PVC or Compounding
Partnership, as the case may be.
 
RIGHT OF FIRST OPTION
 
     Without the consent of the other, neither Geon nor OxyChem may Transfer
less than all of its Partner Sub Stock. Unless such Transfer is otherwise
permitted by the foregoing paragraphs concerning restrictions, neither Geon nor
OxyChem may Transfer its Partner Sub Stock, directly or indirectly, for
consideration other than cash. In addition, unless such Transfer is otherwise
permitted by the foregoing paragraphs, either party (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 will give written notice (the "Initial Notice") to the
appropriate Partnership and the other party (the "Offeree Parent"). The Initial
Notice will state that the Selling Parent has received an Offer or otherwise
desires to Transfer its Partner Sub Stock and state the cash purchase price and
all other terms of the Offer or the cash purchase price and all other terms on
which it otherwise is willing to sell its Partner Sub Stock (the "Offer Terms").
In establishing the Offer Terms for a proposed sale that does not involve an
Offer, the Selling Parent will 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 will constitute the
irrevocable offer of the Selling Parent to sell its Partner Sub Stock to the
Offeree Parent.
 
     The Offeree Parent will have the option, exercisable by delivering written
notice of such exercise to the Selling Parent within 60 days of the date of the
Initial Notice, to elect to purchase all of the Partner Sub Stock of the Selling
Parent on the Offer Terms described in the Initial Notice. 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 will have a
further 180 days during which it may 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 ninety percent (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 will be deemed to have expired and a new notice and
offer will be required before the Selling Parent may make any Transfer of its
Partner Sub Stock. If the Selling Parent receives a written
                                       84
<PAGE>   96
 
offer during such further 180-day period from a third party purchaser that is
for less than ninety percent (90%) of the Fair Market Value, and the Selling
Parent is willing to accept the offer, then (i) the offer will be treated as an
Offer, and (ii) the Selling Parent must comply with right of first refusal and
right of first option procedures before the Selling Parent may make any Transfer
of its Partner Sub Stock to the third party purchaser that made the Offer.
 
     In addition, Geon and OxyChem will agree that each of them can Transfer its
Partner Sub Stock only if the following occur:
 
          (i) the proposed transferor is not in default in the timely
     performance of any of its material obligations to the PVC Partnership or
     the Compounding Partnership, as the case may be;
 
          (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 PVC or the
     Compounding Partnership Governance Committee, as the case may be, and (B)
     to which the PVC Partnership or the Compounding Partnership, as the case
     may be, is a party or by which such Partnership or any of its properties is
     bound;
 
          (iv) the acquiring entity executes an appropriate agreement to be
     bound by the PVC Parent Agreement or the Compounding Parent Agreement, as
     the case may be;
 
          (v) the transferor and transferee bear all reasonable costs incurred
     by the PVC Partnership or the Compounding Partnership, as the case may be,
     in connection with the Transfer;
 
          (vi) Geon or OxyChem, as the case may be, simultaneously Transfers the
     Partner Sub Stock of its other Partner Sub to the acquiring entity or a
     wholly-owned affiliate of such acquiring entity or of a common parent; and
 
          (vii) the acquiring entity must have sufficient resources to assume
     the obligations of Geon or OxyChem, as the case may be, including any
     capital that may reasonably be expected to be requested from its Partner
     Subs by the Partnerships under the then effective strategic plan or the
     acquiring entity's obligations must be supported by a guarantee, letter of
     credit or other credit support reasonably satisfactory to the other party,
     and such acquiring entity must otherwise be reasonably acceptable to the
     other party.
 
     Upon the completion of a permitted Transfer, the acquiring entity will
succeed to and be substituted for Geon or OxyChem, as the case may be, with the
same effect as if such acquiring entity had been named in the applicable Parent
Agreement.
 
     Geon and OxyChem will agree that, until the fifth anniversary of the date
of the Parent Agreements, neither Geon or OxyChem, nor any of its affiliates,
will, without prior written invitation or request of the other party: (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 party,
whether such agreement or proposal is made with or to the other party or a third
party; (ii) make any unsolicited proposal to enter into, directly or indirectly,
any merger or other business combination involving the other party; (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 Commission) to vote,
or seek to advise or influence any person with respect to the voting of, any
voting securities of the other party; (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 (the "Exchange Act") with respect to any voting securities of the
other party; (v) otherwise act, alone or in concert with others, to seek to
control or influence the management, board of directors or policies of the other
party; (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. Geon and OxyChem will also agree during such period not to:
(i) request that the other
 
                                       85
<PAGE>   97
 
party (or its respective directors, officers, employees or agents), directly or
indirectly, amend or waive any provision set forth in this paragraph; or (ii)
take any action that might reasonably be expected to require that the other
party make a public announcement regarding the possibility of a business
combination or merger.
 
     Notwithstanding the foregoing paragraph, as to Geon or OxyChem, as the case
may be, the provisions of the foregoing paragraph will automatically be
terminated and be of no further force and effect if any of any of the following
events occur with respect to the other party: (i) certain changes of control of
such other party will have occurred, (ii) such other party will have entered
into a definitive agreement providing for, or publicly announced its intention
to effect, any transaction involving certain changes of control of such other
party or (iii) a tender offer or exchange offer will have been commenced or
publicly announced that, if consummated, would have the effect of acquiring
beneficial ownership of fifty percent (50%) or more of the voting stock of such
other party.
 
COMPETING BUSINESS
 
     Pursuant to the Compounding Parent Agreement, if either Geon or OxyChem
desires to initiate or pursue any opportunity to undertake, engage in, acquire
or invest in a Business Opportunity, it will agree to offer such Business
Opportunity to the appropriate Partnership under the terms and conditions set
forth in the applicable Partnership Agreement as if it were the "Proposing
Person" with respect thereto, and in such event such Partnership will have the
rights and obligations with respect thereto set forth in its PVC Partnership
Agreement. See "The PVC Partnership Agreement -- Limitation of Fiduciary Duties;
Non-Competition" and "The Compounding Partnership Agreement -- Limitation of
Fiduciary Dates; Non-Competition." Geon's and OxyChem's obligations with regard
to a Business Opportunity will continue until the later of five years after the
date of the Compounding Parent Agreement or until neither of the Partnerships
has both Geon, or any of its affiliates, and OxyChem, or any of its affiliates,
as partners.
 
     If, at any time within five years after the date of the Compounding Parent
Agreement, OPC or any affiliate thereof desires to initiate or pursue an
opportunity to undertake, engage in, acquire a Burlington Type Business, as
defined in the Compounding Parent Agreement (a "Burlington Opportunity"), such
person (a "Burlington Proposing Person") will offer Geon the Burlington
Opportunity on the terms outlined below.
 
     When a Burlington Proposing Person offers a Burlington Opportunity to Geon,
Geon will elect to do one of the following within a reasonably prompt period:
(i) acquire or undertake the Burlington Opportunity for the benefit of Geon as a
whole, at the cost, expense and benefit of Geon; provided, however, that if Geon
ceases to actively pursue such opportunity for any reason, then the Burlington
Proposing Person will be entitled to proceed under clause (ii) below: or (ii)
permit the Burlington Proposing Person to acquire or undertake the Burlington
Opportunity for its own benefit and account without any duty to Geon with
respect thereto.
 
     Notwithstanding the above procedure, if the Burlington Opportunity
constitutes less than 25% (based on annual revenues of the business to be
acquired for the most recently completed fiscal year) of an acquisition of or
investment in assets, activities, operations or businesses that is not otherwise
a Burlington Type Business, then a Burlington Proposing Person may acquire or
invest in such Burlington Opportunity without first offering it to Geon;
provided, that after completion of the acquisition or investment thereof, such
Burlington Proposing Person must offer the Burlington Opportunity to Geon
pursuant to the terms outlined above; and if Geon elects option (i) above with
respect thereto, the Burlington Opportunity will be acquired by Geon at its fair
market value as mutually agreed or finally determined as of the date of such
acquisition.
 
     There are identical provisions in the Compounding Parent Agreement with
respect to OPC or any of its affiliates pursuing an opportunity to undertake a
Pasadena Type Business as defined in the Compounding Parent Agreement.
 
     OxyChem further agrees that, for the period ending on the first anniversary
of the date of the Compounding Parent Agreement, it will not, and will cause its
affiliates not to, directly or knowingly
 
                                       86
<PAGE>   98
 
induce or attempt to induce any employees hired pursuant to the transfer of the
Burlington Subject Business or the Pasadena Subject Business to leave the employ
of Geon; provided, however, that OxyChem and its affiliates will not be
prohibited from hiring or engaging any of the foregoing who respond to a general
solicitation not directed specifically to such employees.
 
     Geon and OxyChem also agree that, for a period ending on the first
anniversary of the date of the PVC Parent Agreement, it will not, and will cause
its affiliates not to directly or knowingly induce or attempt to induce any
officers or employees of the PVC Partnership to leave the employ of the PVC
Partnership; provided, however, that Geon and OxyChem and their affiliates will
not be prohibited from hiring or engaging any of the foregoing who respond to a
general solicitation not directed specifically to officers or employees of the
PVC Partnership.
 
                       CERTAIN RELATED PARTY TRANSACTIONS
 
RESIN PURCHASE AGREEMENT
 
     Pursuant to a Resin Purchase Agreement (the "Resin Agreement"), Geon will
purchase PVC resin from the PVC Partnership.
 
     The Resin Agreement will have an initial term of 15 years and thereafter
will be renewed for two renewal terms of five years each, unless Geon gives
written notice at least two years prior to the end of the initial term of its
intent not to renew. Upon the expiration of the second renewal term, the Resin
Agreement will continue year-to-year. During this evergreen period, either party
may terminate the Resin Agreement upon the end of any term by giving two years
written notice of an intent not to renew.
 
     Either party may terminate the Resin Agreement for cause, if the breach of
the breaching party causes or poses a substantial risk of causing material harm
to the non-breaching party. The Resin Agreement will terminate if the breaching
party fails to cure such breach within 30 days of receiving notice of such
breach from the non-breaching party. If the breach is not reasonably capable of
being cured within 30 days, the breaching party will commence a cure within the
30 day period and continue to pursue the cure diligently thereafter.
 
     Each year during the term of the Resin Agreement, Geon will purchase from
the PVC Partnership its annual requirement of PVC resin, subject to the
following subtractions at Geon's option: (i) 290 million pounds; (ii) Geon's
obligation to receive PVC resins from sources other than the PVC Partnership,
incurred subsequent to the Resin Agreement in connection with an acquisition;
(iii) those quantities of PVC resin which for either quality or suitability
reasons makes product grades produced by the PVC Partnership less than fully
desirable in Geon's reasonable opinion to make particular PVC Compounds; (iv)
those quantities of PVC resin necessary to perform tolling for customers who
wish to have their tolled compound made from PVC resin manufactured by another
person; (v) any increase in Geon's requirements arising after Geon will cease to
hold an interest in the PVC Partnership; and (vi) those quantities of so-called
off-grade and so-called wide-specification PVC resin purchased by Geon for use
in North America.
 
     The Resin Agreement will also provide for the purchase of certain PVC
resins and improved resins which the PVC Partnership will manufacture for and
sell to Geon only. The PVC Partnership grants Geon an opportunity to work with
the PVC Partnership in the development and evaluation of improved resins.
 
     In any calendar quarter, the PVC Partnership may decline to provide to Geon
in excess of three-tenths of the annual quantity of PVC resin most recently
forecasted for the then-current calendar year. In any calendar month, the PVC
Partnership may decline to provide Geon the excess over 120% of the quantity of
a particular PVC resin most recently forecasted for the calendar month.
 
   
     On the first 880 million pounds of PVC resin supplied in any calendar year,
Geon's approximate initial requirements, Geon will pay a price which is based
upon cost and market price considerations. Geon will purchase all volumes over
the 880 million pounds in any calendar year at a competitive market price. Geon
believes that the pricing under the Resin Agreement approximates the market
price that would be available to a purchaser of similar volumes for similar
transactions with third parties.
    
 
                                       87
<PAGE>   99
 
     The PVC Partnership at its own cost and expense will use commercially
reasonable efforts to work with Geon to develop improved resins to meet Geon's
needs, and Geon will give the PVC Partnership a first "look" for a commercially
reasonable time to develop such improved resins. The PVC Partnership undertakes
to implement a long-term resin development program to develop both improved
resins having certain agreed upon general properties and those which advances in
technology may make desirable.
 
VINYL CHLORIDE MONOMER PURCHASE AGREEMENT
 
     Pursuant to a Vinyl Chloride Monomer Purchase Agreement (the "VCM
Agreement"), Geon will purchase VCM from the PVC Partnership.
 
     The VCM Agreement will have an initial term of 15 years, and thereafter
will be renewed for two renewal terms of five years each, unless Geon gives
written notice at least two years prior to the end of the initial term of its
intent not to renew. Upon the expiration of the second renewal term, the VCM
Agreement will continue year-to-year. During this evergreen period, either party
may terminate the VCM Agreement upon the end of any term by giving two years
written notice of an intent not to renew.
 
     Either party may terminate the VCM Agreement for cause, if the breach of
the breaching party causes or poses a substantial risk of causing material harm
to the non-breaching party. The VCM Agreement will terminate if the breaching
party fails to cure such breach within 30 days of receiving notice os such
breach from the non-breaching party. If the breach is not reasonably capable of
being cured within 30 days, the breaching party will commence a cure within the
30 day period and continue to pursue the cure diligently and responsibly
thereafter.
 
     Each year during the term of the VCM Agreement, Geon will purchase from the
PVC Partnership its annual requirement of VCM. In any calendar quarter, the PVC
Partnership may decline to provide to Geon in excess of three-tenths of the
annual quantity of VCM most recently forecasted for the then-current calendar
year. In any calendar month, the PVC Partnership may decline to provide to Geon
the excess over 120% of the quantity of VCM most recently forecasted for the
calendar month.
 
     For VCM purchased under the VCM Agreement, Geon will pay the North American
large buyer contract price less quarterly adjustments and rebates customary in
the industry. On the first 210 million pounds purchased in any calendar year,
Geon's approximate initial requirements, Geon will receive an integration
adjustment to the price.

                       COMPENSATION OF DIRECTORS OF GEON
 
     Directors unaffiliated with Geon are paid an annual retainer of $20,000 and
fees of $1,000 for each Board and Committee meeting attended. In addition, the
chairman of each Committee receives a fixed annual retainer of $3,000. In
addition, upon retirement from the Geon Board after reaching the age of 55 with
at least ten years of service as a Director, any Director unaffiliated with Geon
is entitled to receive
 
                                       93
<PAGE>   105
 
an annual amount equal to the fixed compensation level in effect at the time of
retirement. A retiring Director who has reached age 55 and has served for at
least five but less than ten years is entitled to a reduced amount equal to 50%
of the fixed compensation level in effect at retirement, plus 10% of such
compensation level for each additional year of service (rounded to the nearest
whole year) up to ten. Directors are reimbursed for their expenses associated
with each meeting attended.
 
     Under the Directors Deferred Compensation Plan, each Director who is not an
employee may defer payment of all or a portion of his or her compensation as a
Director. The compensation may be deferred as cash or converted into Geon Common
Stock (at a rate equal to 125% of the cash compensation amount). Deferred
compensation, whether in the form of cash or Geon Common Stock, is held in trust
for the participating Directors. Interest earned on the cash amounts and
dividends on the Geon Common Stock accrue for the benefit of the participating
Directors.
 
     Under Geon's 1995 Incentive Stock Plan (the "1995 Incentive Plan"), each
current Director who was not an employee of Geon was granted on the date of the
1995 Annual Meeting an option to acquire 5,000 shares of Common Stock. Each new
Director who is not an employee of Geon is granted at the time of his or her
election or appointment a Director option to acquire 5,000 shares of Geon Common
Stock. Each such Director who continues in office following the initial grant
receives an additional Director option to acquire 1,000 shares of Geon Common
Stock annually on the anniversary date of the previous option grant.

(1) Amounts represent the aggregate bonus payments to the named executive under
    the Executive MIP for 1998, 1997 and 1996. The Executive MIP provided that a
    minimum of 40% of the named executives' bonus awards, if any, under the plan
    would be paid in the form of restricted stock awarded under Geon's incentive
    stock plans. The participant may also elect to receive all or any portion of
    the balance in the form of restricted stock. For each $1 of the bonus amount
    paid in the form of restricted stock, $1.25 worth of restricted stock is
    awarded. The portion of the award, if any, not paid in restricted stock is
    paid in cash. Under the terms of the restricted stock award, the restricted
    stock awarded may not be transferred for the three-year period following the
    date of award. In the event a participant leaves the employ of Geon prior to
    the lapse of the restrictions (other than by reason of death, disability or
    retirement), the participant will forfeit up to 100% of the 25% premium
    received in respect of the award. The amount of cash (including payments in
    respect of fractional shares) and the market value and number of the shares

(3) In 1998, William F. Patient was awarded 11,000 shares of restricted stock in
    lieu of participation in Geon's 1998-2000 Long-Term Incentive Plan. Except
    as described in footnote 1, there were no other awards of restricted stock
    in 1998, 1997, or 1996 to the named executive officers.
 
(4) Amounts for 1998 represent the number of shares paid out to the named
    executive on January 1, 1998 in respect of performance shares awarded to the
    named executive in 1995 under Geon's 1995-1997 Long-Term Incentive Plan. The
    number of shares awarded was based on Geon's achievement of performance
    objectives specified under such plan for the three-year period ended
    December 31, 1997, and are net of withholding taxes.
 
(5) Amounts for 1998 represent, respectively, Geon's cash contributions on
    behalf of the named executives to Geon's Retirement Savings Plan, amounts

(1) Of the options granted to W.F. Patient, 70,000 will become exercisable on
    August 1, 1999 and 35,000 will become exercisable upon achievement of stock
    price performance targets on or before December 31, 2001 as specified in the
    Company's 1998-2000 Long-Term Incentive Plan. Two-thirds of the options
    granted to the other four named executives vest in six years, with
    accelerated vesting upon achievement of stock price performance targets
    defined in the 1998-2000 Long-Term Incentive Plan. The remaining one-third
    of the options granted will vest only upon achievement of stock price
    performance targets on or before December 31, 2001 as defined in the plan.
    All of the options were granted with limited stock appreciation rights which
    generally entitle the optionee to elect to receive the appreciation on the
    option in cash for a 60 day period following a "change in control" and were
    granted with exercise prices not less than 100% of the fair market value of
    Common Stock.
 
(2) The grant date fair values shown in the table were determined pursuant to
    the Black-Scholes option valuation model (a widely used stock option
    valuation methodology), using the following assumptions: stock price
    volatility factor of .2990; dividend yield of 2.58%; interest rate of 4.80%;
    and a ten year term. There were no adjustments made for non-transferability
    or risk of forfeiture. The actual value, if any, that an executive officer
    may realize from his or her stock options (assuming that they are exercised)
    will depend solely on any gain in stock price over the exercise price when
    the shares are sold.

RETIREMENT PENSIONS
 
     Geon has in effect a pension plan for salaried employees which provides
pensions payable at retirement to each eligible employee. The plan makes
available a pension which is paid from funds
 
                                       96
<PAGE>   108
 
provided through contributions by Geon and contributions by the employee, if
any, made prior to 1972. The amount of an employee's pension depends on a number
of factors including Final Average Earnings ("FAE") and years of credited
service to Geon. The following chart shows the annual pension amounts currently
available to employees who retire with the combinations of FAE and years of
credited service shown in the chart, which should be read in conjunction with
the notes following the chart. As of January 1, 1989, the plan generally
provides a benefit of 1.15% of FAE times all years of pension credit plus 0.45%
of FAE in excess of covered compensation times years of pension credit up to 35
years. In addition, employees actively at work on December 31, 1989, may receive
an additional pension credit of up to 4 years up to a maximum of 24 years of
pension credit. Benefits become vested after 5 years of service.

(1) Assumes actively employed January 1, 1990, and after.
 
(2) Includes an additional 4 years of service applicable to pre-January 1, 1990,
    employees.
 
(3) The pension plan uses either a "final average earnings" formula or a
    "service credit" formula to compute the amount of an employee's pension,
    applying the formula which produces the higher amount. The above chart was
    prepared using the FAE formula, since the service credit formula would
    produce lower amounts than those shown. Under the FAE formula, a pension is
    based on the highest four consecutive calendar years of an employees'
    earnings. Earnings include salary, overtime pay, holiday pay, vacation pay,
    and certain incentive payments including annual cash bonuses, but exclude
    awards under long-term incentive programs and Geon match in Geon savings
    plans. As of December 31, 1997, final average earnings for the individuals
    named in the Summary Compensation Table were as follows: W.F.
    Patient-$873,493.29; T.A. Waltermire-$435,410.27; D.P.
    Knechtges-$316,556.37; W.D. Wilson-$222,642.28; and G.L. Rutman-
    $271,670.31.
 
(4) In computing the pension amounts shown, it was assumed that an employee
    would retire at age 65 and elect to receive a five year certain and
    continuous annuity under the pension plan and that the employee would not
    elect any of the available "survivor options," which would result in a lower
    annual pension. Pensions are not subject to any reduction for Social
    Security or any other offset amounts.
 
(5) As of December 31, 1998, the five executive officers named in the cash
    compensation table had the following years of credited service under the
    pension plan or subsidiary plans or supplemental agreements: W.F. Patient, 9
    years, 6 months; T.A. Waltermire, 24 years, 6 months; D.P. Knechtges, 33
    years, 6 months; G.L. Rutman, 24 years, 2 months; and W.D. Wilson, 20 years,
    11 months.
 
(6) W.F. Patient became vested in benefits immediately and earns an additional
    benefit equal to 1.6 percent of his final average annual earnings for each
    of his first 15 years with Geon. These benefits are payable under an
    unfunded, non-qualified supplemental plan.

(7) Benefits shown in the chart that exceed the level of benefits permitted to
    be paid from a tax-qualified pension plan under the Internal Revenue Code of
    1986, as amended (the "Code"), and certain additional benefits not payable
    under the qualified pension plan because of certain exclusions from
    compensation taken into account thereunder, are payable under an unfunded,
    non-qualified supplemental pension plan.
 
MANAGEMENT CONTINUITY AGREEMENTS
 
     Geon has entered into management continuity agreements (the "Continuity
Agreements") with certain employees, including all of the executive officers
named in the Summary Compensation Table. The purpose of the Continuity
Agreements is to encourage the individuals to carry out their duties in the
event of the possibility of a "change of control" of Geon. The Continuity
Agreements do not provide any assurance of continued employment unless there is
a change of control. The Continuity Agreements generally provide for a two-year
period of employment commencing upon a change of control, which generally is
deemed to have occurred if: (i) any person becomes the beneficial owner of 20%
or more of the combined voting power of Geon's outstanding securities (subject
to certain exceptions), (ii) there is a change in the majority of the Geon
Board, (iii) certain corporate reorganizations occur where the existing
stockholders do not retain more than 60% of Geon Common Stock and combined
voting power of the outstanding voting securities of the surviving entity, or
(iv) there is shareholder approval of a complete liquidation or dissolution of
Geon.
 
     The Continuity Agreements generally provide for the continuation of
employment of the individuals in the same positions and with the same
responsibilities and authorities that they possessed immediately prior to the
change of control and with the same benefits and level of compensation,
including average annual increases. If the individual's employment is terminated
by Geon or its successor for reasons other than "cause" or is terminated
voluntarily by the individual for "good reason" (in each case as defined in the
Continuity Agreements), generally the individual would be entitled to receive:
(i) compensation for a period of up to three years, commencing at the
individual's base salary rate in effect at the time of the termination and
including average annual increases thereafter, (ii) the continuation of all
employee benefits and perquisites, and (iii) a lump sum equal to the total of
(A) up to three times the individual's annualized incentive compensation, which
will be equal to the greater of that paid with respect to the calendar year
prior to such termination or the "target incentive amount" (as defined in the
Continuity Agreements) for the year of the change of control or the year of
termination and (B) up to three times the "calculated market value" of the
"restricted stock" and "performance stock" awarded to the individual in Geon's
most recent "plan cycle" (in each case as defined in the Continuity Agreements).
The Continuity Agreements also provide for a tax gross-up for any excise tax due
under the Code for any payments or distributions made under the agreements.
 
                         PROPOSAL TWO: THE GEON COMPANY
                           1999 INCENTIVE STOCK PLAN
 
SUMMARY
 
     The purpose of this proposal is to approve The Geon Company 1999 Incentive
Stock Plan (the "1999 Incentive Stock Plan"). The 1999 Incentive Stock Plan will
permit awards to qualify as performance-based compensation under Section 162(m)
of the Code and will provide the Compensation Committee (the "Committee") with
increased flexibility in administering Geon's compensation policy. The 1999
Incentive Stock Plan is similar to in most respects The Geon Company 1995
Incentive Stock Plan (the "1995 Incentive Stock Plan").
 
DISCUSSION
 
     On November 4, 1998, the Committee adopted, subject to stockholder
approval, the 1999 Incentive Stock Plan and the Geon Board recommended that the
1999 Incentive Stock Plan be approved by the stockholders at the Special
Meeting. The 1999 Incentive Stock Plan is contingent on stockholder
                                       98
<PAGE>   110
 
approval at the Special Meeting. The 1999 Incentive Stock Plan, if approved,
will replace the 1995 Incentive Stock Plan and The Geon Company Interim Stock
Award Plan ("Interim Plan") once the shares under those plans are exhausted,
which the Company expects will occur during 1999.
 
     The Geon Board believes the 1999 Incentive Stock Plan will foster the
long-term growth and performance of Geon by enhancing Geon's ability to attract
and retain qualified non-employee directors and key employees and by motivating
directors and key employees through stock ownership and performance-based
incentives without limiting Geon's ability to deduct certain compensation
awarded under the 1999 Incentive Stock Plan for federal income tax purposes.
 
     Like Geon's 1995 Incentive Stock Plan, the 1999 Incentive Stock Plan
provides authority for the grant of stock options, restricted stock, stock
equivalent units, stock appreciation rights, performance-based stock awards, and
other stock and performance-based incentives.
 
     Section 162(m) of the Code and the proposed rules and regulations
thereunder provide that certain employee compensation for years beginning after
December 31, 1993, in excess of $1,000,000 will not be deductible for federal
income tax purposes. Section 162(m), however, enumerates certain types of
compensation which will not be subject to the $1,000,000 limitation, including
"performance-based" compensation. Among other requirements, Section 162(m)
requires that in order for compensation to qualify as performance-based, the
material terms of the compensation and the performance goals on which payment of
such compensation is conditioned must be disclosed to, and approved by, the
stockholders before payment is made.
 
     The 1999 Incentive Stock Plan provides for the payment of certain
performance based awards that, subject to stockholder approval, will qualify as
"performance-based" compensation under Section 162(m).
 
     If approved by the stockholders, the 1999 Incentive Stock Plan will be
effective for the fiscal year which began on January 1, 1999, and for each
fiscal year thereafter until terminated. The 1999 Incentive Stock Plan will
replace the 1995 Incentive Stock Plan and Interim Stock Award Plan once the
shares under the 1995 Incentive Stock Plan and Interim Plan are exhausted, which
the Company expects will occur during 1999. In the event that the stockholders
do not approve the 1999 Incentive Stock Plan, no awards will be made under the
1999 Incentive Stock Plan, although other incentive awards may be paid in the
future at the discretion of the Committee.
 
     A copy of the 1999 Incentive Stock Plan is attached as Annex C to this
Proxy Statement and the following summary of the material terms of the 1999
Incentive Stock Plan is qualified in its entirety by reference to that Annex.
 
     All key employees of Geon and its affiliates, including officers whether or
not Directors, and non-employee Directors are eligible for the grant of awards.
The selection of individuals to receive awards will be within the discretion of
the Committee. If the 1999 Incentive Stock Plan were currently in effect,
approximately 100 employees and Directors of Geon would be eligible to
participate.
 
     The aggregate number of shares of Geon Common Stock that may be subject to
awards granted under the 1999 Incentive Stock Plan is 1,000,000. Geon Common
Stock subject to an award that expires or is forfeited, terminated, or canceled
will again be available for grant under the 1999 Incentive Stock Plan, without
reducing the number of shares of Geon Common Stock available for grant of
awards, except to the extent that the availability of those shares of Geon
Common Stock would cause the 1999 Incentive Stock Plan or any awards granted
under the 1999 Incentive Stock Plan to fail to qualify for the exemption
provided by Rule 16b-3. If a 1999 Incentive Stock Plan participant pays all or
part of the exercise price of an award by the transfer of shares of Geon Common
Stock or the surrender of all or part of an award (including the award being
exercised), the number of shares of Geon Common Stock transferred or
attributable to the portion of the award surrendered will also be available for
grant. The number of shares of Geon Common Stock attributable to any award that
is settled in cash will, upon settlement, also be available for grant.
 
                                       99
<PAGE>   111
 
     The aggregate number of shares of Geon Common Stock that may be issued upon
exercise of incentive stock options is 1,000,000. The maximum number of shares
of Geon Common Stock with respect to which awards may be granted under the 1999
Incentive Stock Plan to a non-employee director in any one fiscal year is
10,000. The aggregate number of shares of restricted stock (other than
restricted stock which is a performance-based stock award) that may be awarded
under the 1999 Incentive Stock Plan is 200,000. No participant who is an
employee may be awarded performance-based stock awards in any one fiscal year in
excess of an aggregate of 50,000 shares of Geon Common Stock. The maximum number
of shares with respect to which options (including incentive stock options) and
stock appreciation rights may be granted in any period of three fiscal years to
any individual participant is 250,000.
 
     In the event of any change in the number of shares of Geon Common Stock by
reason of a consolidation, reorganization, recapitalization, or similar
transaction, or in the event of a stock dividend, stock split, or distribution
to stockholders (other than normal cash dividends), the Committee will adjust
the number and class of shares that may be issued under the 1999 Incentive Stock
Plan, the number and class of shares subject to outstanding awards, the exercise
price applicable to outstanding awards, and the fair market value of the shares
of Geon Common Stock and other value determinations applicable to outstanding
awards.
 
     The 1999 Incentive Stock Plan will be administered by the Committee. The
Committee will have the authority to select the eligible employees and
non-employee Directors who will receive awards, grant awards, determine the
number and types of awards, determine the terms, conditions, vesting periods,
and restrictions applicable to awards, adopt, alter, and repeal administrative
rules and practices governing the 1999 Incentive Plan, interpret the terms and
provisions of the 1999 Incentive Stock Plan and of any awards granted, prescribe
the forms of any notices of award, award agreements, or other instruments
relating to awards, and to otherwise supervise the administration of the 1999
Incentive Stock Plan.
 
     The Committee may delegate any of its authority to any other person or
persons that it deems appropriate, provided the delegation does not cause the
1999 Incentive Stock Plan or any awards granted under the 1999 Incentive Stock
Plan to fail to qualify for the exemption provided by Rule 16b-3 under the
Exchange Act for transactions by certain persons in Geon Common Stock.
 
     Awards may be granted singly or in combination or tandem with other awards.
Awards may also be granted in replacement of, or in substitution for, other
awards granted by Geon, whether or not such awards were granted under the 1999
Incentive Stock Plan. With respect to performance-based stock awards, the new
award must also be wholly contingent on the attainment of performance goals
established by the Committee. If a participant pays all or part of the exercise
price or taxes associated with an award by the transfer of Geon Common Stock or
the surrender of all or part of an award (including the award being exercised),
the Committee may, in its discretion, grant a new award (which, in the case of
awards intended to replace performance-based stock awards, must also be wholly
contingent on the attainment of performance goals established by the Committee)
to replace the shares of Geon Common Stock that were transferred or the award
that was surrendered. Geon may assume awards granted by an organization acquired
by Geon or may grant awards in replacement of, or in substitution for, any such
awards.
 
     The Committee may, in its discretion, grant stock awards under the 1999
Incentive Stock Plan valued by reference to shares of Geon Common Stock that are
wholly contingent on the attainment of performance goals established by the
Committee from time to time. It is intended that performance-based stock awards
will constitute performance based compensation under Section 162(m) of the Code.
 
     The performance goals will relate to one or more of the following
performance measures, as determined by the Committee for each applicable
performance period: (i) return to stockholders, (ii) cash flow, (iii) return on
equity, (iv) Geon created income (for example, income due to Geon initiated cost
reductions or productivity improvements), (v) sales growth, (vi) earnings and
earnings growth,
                                       100
<PAGE>   112
 
(vii) return on assets, (viii) stock price, (ix) earnings per share, (x) market
share, (xi) customer satisfaction, and (xii) safety and/or environmental
performance. The number or value of performance-based stock awards that will be
paid out to any participant at the end of the applicable performance period,
which may be one year or longer as determined by the Committee, will depend on
the extent to which Geon attains the established performance goals.
 
     With the approval of the Committee, the delivery of Geon Common Stock,
cash, or any combination thereof subject to an award may be deferred by a
participant. Certain participants may also be permitted to defer the payment of
some or all of their awards under the 1995 Incentive Stock Plan. Deferred
amounts may, to the extent permitted by the Committee, be credited as cash or
stock equivalent units.
 
     The exercise price of a stock option and any stock award for which the
Committee has established an exercise price may be paid in cash, by the transfer
of Geon Common Stock, by the surrender of all or part of an award (including the
award being exercised), or by a combination of these methods, as and to the
extent permitted by the Committee. To the extent that the exercise price of an
incentive stock option is paid by the surrender of an award, such an exercise
may constitute a disqualifying disposition of the incentive stock option
resulting in the recognition by the participant of ordinary income.
 
     In the event shares of restricted stock are used to pay the exercise price
of a stock award, a number of shares of Geon Common Stock issued upon the
exercise of the award equal to the number of shares of restricted stock used to
pay the exercise price will be subject to the same restrictions as the
restricted stock.
 
     In the event of a change in control of Geon (as defined in the 1999
Incentive Stock Plan), unless and to the extent otherwise determined by the Geon
Board, (i) all stock appreciation rights and stock options then outstanding will
become fully exercisable as of the date of the change in control and (ii) all
restrictions and conditions applicable to restricted stock and other stock
awards, including performance-based stock awards, will be deemed to have been
satisfied as of the date of the change in control. Any such determination by the
Geon Board that is made after the occurrence of a change in control will not be
effective unless a majority of the directors then in office are continuing
directors (as defined in the 1999 Incentive Stock Plan) and the determination is
approved by a majority of the continuing directors. In the event of a change in
control, the deemed satisfaction of the conditions applicable to performance-
based compensation will cause such compensation to qualify as performance-based
compensation under Section 162(m). Notwithstanding any other provision of the
1999 Incentive Stock Plan, during the 60 day period from and after a change of
control, unless the Committee determines otherwise at the time of the grant, an
optionee will have the right, whether or not a stock option is fully exercisable
and in lieu of payment of the exercise price, to elect (within the 60 day
period) to surrender all or part of the option and receive cash in an amount
equal to the "spread" between the change of control price (as defined in the
1999 Incentive Stock Plan) per share and the exercise price per share multiplied
by the number of shares as to which the right is exercised.
 
     The Geon Board may amend, suspend, or terminate the 1999 Incentive Stock
Plan at any time. Stockholder approval for any such amendment will be required
only to the extent necessary to preserve the exemption provided by Rule 16b-3
under the Exchange Act for the 1999 Incentive Stock Plan and awards granted
under the 1999 Incentive Stock Plan.
 
     The Committee may, in its discretion, amend the terms of any award,
prospectively or retroactively, but no such amendment may impair the rights of
any participant without his or her consent or cause awards intended to qualify
as performance-based compensation under Section 162(m) to fail to so qualify.
The Committee may, in whole or in part, waive any restrictions or conditions
applicable to, or accelerate the vesting of, any award.
 
     The 1999 Incentive Stock Plan will become effective on the date it is
approved by stockholders and will continue in effect until terminated by the
Geon Board.
 
     The anticipated income tax treatment to Geon and the participants, under
current provisions of the Code, of the grant and exercise of awards is briefly
discussed in Annex C to this Proxy Statement.

     While awards under the 1999 Incentive Stock Plan are not yet determinable,
information regarding awards under Geon's 1995 Incentive Stock Plan to Geon's
executive officers is set forth above under the headings "Summary Compensation
Table" and "Option/SAR Grants in Last Fiscal Year" on pages 93 and 95,
respectively.
    
 
     The Geon Board recommends a vote "FOR" adoption of the 1999 Incentive Stock
Plan. The affirmative vote of the holders of at least a majority of the votes
cast (including abstentions) on this proposal is required to adopt the 1999
Incentive Stock Plan.

Stockholders, Geon must have received proposals which stockholders intend to

                    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, 1997 and 1996,
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, 1997. 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, 1997 and 1996, 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, 1997, in conformity with generally accepted
accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
                        DECEMBER 31, 1997, 1996 AND 1995
(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.
 
     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

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
                        DECEMBER 31, 1997, 1996 AND 1995
 
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 $14 million and $46 million, respectively, at
December 31, 1997.
 
     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.
 
  Equity investment --
 
     The OxyChem Transferred Businesses' fifty percent interest in OxyMar is
accounted for on the equity method. At December 31, 1997 and 1996, the
historical underlying equity in net assets of OxyMar exceeded the OxyChem
Transferred Businesses' investment in OxyMar by $8.8 million and $9.3 million,
respectively. The investment deficiency is being amortized on a straight-line
basis into

</TABLE>
 
     As of December 31, 1997, OPC unconditionally provides guarantees of $188
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 Occidental 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.
 
  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, 1997 and 1996, the OxyChem Transferred Businesses
transferred, with limited recourse, to an OPC affiliate net domestic 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 trade receivables transferred amounted to approximately $85
million and $76 million as of December 31, 1997 and 1996, 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 $3.9 million, $3.2 million and $3.9 million for 1997, 1996 and 1995,
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):

</TABLE>
 
     During 1996, certain inventories carried at LIFO were reduced resulting in
a liquidation of quantities carried at lower costs prevailing in prior years as
compared with the cost of 1996 purchases. This liquidation decreased cost of
sales by $383,000 in 1996.
 
(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. The
amount of interest allocated and capitalized was approximately $6 million, $2
million and $1 million for the years ended December 31, 1997, 1996, and 1995,
respectively.

     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, 1997,
1996, and 1995 were $8.0 million, $7.3 million, and $5.5 million, respectively.

     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, 1997, $8 million of the long-term debt was guaranteed by
OPC.
 
(9) RETIREMENT PLANS AND POSTRETIREMENT BENEFITS --
 
     The OxyChem Transferred Businesses participate in various defined
contribution retirement plans sponsored by OPC for its salaried, domestic union
and nonunion hourly 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 1997, 1996 and 1995.
 
     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 for union hourly employees 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.

</TABLE>
 
     The discount rate used in determining the actuarial present value of the
projected benefit obligations was 7.5 percent in 1997 and 1996. The rate of
increase in future compensation levels used in determining the actuarial present
value of the projected benefit obligations was 4.5 percent in 1997 and 1996. The
expected long-term rate of return on assets was 8 percent in 1997 and 1996.
 
  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, 1997 and 1996, 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 3 percent in 1997 (except for union
employees). For union employees, the health care cost trend rates were projected
at annual rates ranging ratably from 8.5 percent in 1997 to 5 percent through
the year 2004 and level thereafter. The effect of a one percent annual increase
in these assumed cost trend rates would increase the allocated accumulated
postretirement benefit obligation by approximately $1.2 million and the
allocated annual service and interest costs by approximately $120,000 in 1997.
The weighted average discount rate used in determining the accumulated
postretirement benefit obligation as of December 31, 1997 and 1996, was 7.5
percent. The plans are unfunded.

  Lawsuits --
 
     OxyChem has been named as defendant or as 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.

                          SEPTEMBER 30, 1998 AND 1997
(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 (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 Pellet 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 Pellet
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. 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 -- (CONTINUED)
 
                                   UNAUDITED
 
                          SEPTEMBER 30, 1998 AND 1997
 
     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 $13
million and $43 million, respectively, at September 30, 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.
 
     Certain information and disclosures normally included in the notes to
financial statements have been condensed or omitted pursuant to Securities and
Exchange Commission rules and regulations, but resultant disclosures are in
accordance with generally accepted accounting principles as they apply to
interim reporting. These interim financial statements should be read in
conjunction with the OxyChem Transferred Businesses audited financial statements
as of December 31, 1997 ("1997 Financial Statements").
 
     In the opinion of OxyChem's management, the accompanying interim financial
statements contain all adjustments (consisting of normal recurring adjustments)
necessary to present fairly the combined financial position as of September 30,
1998, and the results of operations and changes in invested capital and cash
flows for the nine months ended September 30, 1998 and 1997, of the OxyChem
Transferred Businesses. The results of operations and cash flows for the nine
months ended September 30, 1998, are not necessarily indicative of the results
of operations or cash flows to be expected for the full year.
 
(2)  SIGNIFICANT ACCOUNTING POLICIES --
 
  Principles of combination --
 
     The combined financial statements include assets and liabilities and the
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' 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.

                          SEPTEMBER 30, 1998 AND 1997
 
  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.
 
  Equity investment --
 
     The OxyChem Transferred Businesses' fifty percent interest in OxyMar is
accounted for on the equity method. At September 30, 1998, the historical
underlying equity in net assets of OxyMar exceeded the OxyChem Transferred
Businesses' investment in OxyMar by $8.5 million. 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 for the nine
months ended September 30 (in thousands).

(5)  OTHER ASSETS --
 
     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. Deferred start-up costs of $3,824,000 have been
included in other assets in the accompanying Combined Balance Sheet as of
September 30, 1998.

     Rental expense for railcars was approximately $12 million and $11 million
for the nine months ended September 30, 1998 and 1997, respectively.
 
  Lawsuits --
 
     OxyChem has been named as defendant or as potentially responsible party
with regard to the OxyChem Transferred Businesses in a number of lawsuits,
claims and proceedings, including governmental proceedings under 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.
 
  Other --
 
     The OxyChem Transferred Businesses have entered into an agreement providing
for the following minimum future payments to purchase brine, a raw material, as
of September 30, 1998 (in thousands).

     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 $32.7 million for the nine months ended September 30,
1998, and $31.7 million for the nine months ended September 30, 1997, 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, were
approximately $2.1 million in each of the nine month periods ended September 30,
1998 and 1997.
 
     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, were
approximately $40 million and $53 million for the nine months ended September
30, 1998 and 1997, respectively.
 
     The OxyChem Transferred Businesses purchase VCM from OxyMar under the terms
of a VCM purchase agreement between OxyChem and OxyMar that runs for the life of
the OxyMar partnership. Purchases are at market prices and totaled approximately
$75 million and $62 million for the nine months ended September 30, 1998 and
1997, respectively. Accounts payable as of September 30, 1998, include
approximately $7 million payable to OxyMar. The OxyChem Transferred Businesses
purchase ethylene at market prices from an affiliate of OxyChem. These purchases
totaled approximately $68.4 million and $103.7 million during the nine months
ended September 30, 1998 and 1997, respectively.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                         OXYCHEM TRANSFERRED BUSINESSES
 
     The OxyChem Transferred Businesses consist of the following assets and
businesses and certain related assets and businesses of OxyChem: (i) its vinyl
chloride monomer ("VCM") facility in Deer Park, Texas; (ii) its suspension/mass
polyvinyl chloride ("PVC") facility in Pasadena, Texas; (iii) its fifty percent
investment interest in OxyMar, a Texas general partnership which owns a VCM
plant in Ingleside, Texas; (iv) its Houston Chlor-Alkali complex facilities,
which produce chlorine and caustic soda (both liquid and dry); (v) its powder
compound business and related assets at its Pasadena, Texas facility; (vi) its
specialty cube or pellet compound business being constructed and installed at
its Pasadena, Texas plant; and (vii) its Burlington, New Jersey, plant (the
"Burlington Plant"), which manufactures flexible film and compounding PVC for
molding applications.
 
     Set forth below are (i) a discussion of certain industry-wide business
conditions affecting the OxyChem Transferred Businesses, (ii) a discussion of
the results of operations of the OxyChem Transferred Businesses for the nine
months ended September 30, 1998, compared to the corresponding period of the
previous year, and for the fiscal years ended December 31, 1997, 1996 and 1995,
each compared to the respective preceding fiscal years, and (iii) a discussion
of the liquidity and capital position of the OxyChem Transferred Business.
 
     The combined financial statements for the OxyChem Transferred Businesses
and the discussion below present the financial position and results of
operations of the assets and businesses included in the OxyChem Transferred
Businesses as if these businesses were and were going to be operated as one
combined business as of the dates and during the periods indicated. Prior to the
preparation of the combined financial statements for purposes of the Joint
Venture Transactions, however, OxyChem did not prepare separate financial
statements for the OxyChem Transferred Businesses. See "Notes to Combined
Financial Statements -- (1) Basis of Presentation and Description of the
Transferred Businesses" and "-- (12) Summarized Financial Information."
Moreover, in the Joint Venture Transactions, Geon will acquire certain
components of the OxyChem Transferred Businesses indirectly and in part only, in
the case of the PVC Partnership and the Compounding Partnership. See "The Joint
Venture Transactions."
 
BUSINESS CONDITIONS
 
     The OxyChem Transferred Businesses are affected by cyclical factors in the
general economic environment and by specific chemical industry conditions. Also,
most of the products of the OxyChem Transferred Businesses are commodity in
nature, the demand for, and prices of, which are sensitive to a number of
complex factors. Accordingly, OxyChem management is generally unable to forecast
accurately the trend of sales or sales prices for its commodity chemical
products. However, in 1998, the OxyChem Transferred Businesses have experienced
a period of historically low commodity chemical prices that have adversely
affected earnings, and such trend is expected to continue in 1999. Below is a
discussion of some of the industry-wide conditions and factors affecting the
OxyChem Transferred Businesses.
 
NORTH AMERICAN PVC INDUSTRY STATUS
 
  Production Capacity and Operating Rates
 
     The total North American PVC production capacity is forecasted to increase
by 4.0% in 1998 compared to capacity at the end of 1997. This increased capacity
was partially offset, however, by increased domestic demand and export volume.
As a result primarily of the foregoing factors, operating rates averaged 88.5%
for the nine months ended September 30, 1998 ("YTD"), compared to 89.3% for the
same period in 1997. Total production YTD was up by 3.8% as compared to the same
period of 1997, with production reaching 4.94 million metric tons for the nine
months ended September 30, 1998 versus 4.76 million metric tons for the same
period of 1997.
                                      F-27
<PAGE>   141
 
  Domestic Demand
 
     PVC demand YTD was up 4.6% compared to 1997 levels for the same period.
Total domestic demand for PVC reached 4.54 million metric tons YTD compared to
4.34 million metric tons in 1997 for the same period. This increase is
attributed primarily to increased demand in the construction industry. About 80%
of domestic PVC demand is related to the construction industry, with housing
starts being one of the leading indicators of construction activity. Housing
starts averaged 1.59 million units on a seasonally adjusted annual rate basis in
YTD 1998 compared to a 1.46 million unit level for the same period in 1997, a 9%
increase. Domestic demand for PVC siding, pipe fittings, wire & cable, windows &
door and custom extrusion also increased YTD as compared to the same period in
1997.
 
  Exports
 
     YTD PVC exports were down by 0.5%, at 467 thousand metric tons, compared to
1997 exports during the same period of 470 thousand metric tons. The export
market grew during the first two quarters of 1998, but began to slow in June due
to the Asian crisis. The primary export markets consist of Latin America, the
Middle East and Africa. Export volumes are likely to erode further as the Asian
economies struggle to stabilize and major Latin American economies, such as
Brazil, Argentina and Venezuela, currently appear to be slowing down. In
addition, Latin American PVC producers are planning to bring onstream new
capacity of approximately 343 thousand metric tons in 1999, which will likely
further erode the export volumes in future periods of individual PVC exporters,
including the OxyChem Transferred Businesses.
 
  Pricing
 
     Excess supply of PVC, in conjunction with lower demand in many countries in
Asia, has put severe downward pressure on selling prices and intensified
competitive market conditions. The world supply/demand balance is not expected
to improve unless and until the Asian markets improve.
 
NORTH AMERICAN CHLOR-ALKALI INDUSTRY STATUS
 
  Production Capacity and Operating Rates
 
     The North American production capacity increased by 2.9% as of September
30, 1998, compared to the capacity at September 30, 1997. Despite the increased
capacity, chlor-alkali production YTD remained at the same level as in 1997 for
the same period. Industry-wide operating rates are forecast to be 95% for fiscal
1998 compared to 98% for fiscal 1997. Capacity is expected to increase by nearly
5% in 1999.
 
  Domestic Chlorine Demand
 
     Demand for chlorine in the pulp and paper, titanium dioxide,
epichlorohydrin and bromine market segments decreased in the 1998 YTD period
compared to the same period in 1997. The volume of chlorine based finished
product shipped to Asia decreased in each of these segments forcing a decrease
in production and ultimately chlorine consumption. The new chlorine capacity
brought on stream in late 1997 has reduced the market share available to all
chlorine producers including the OxyChem Transferred Businesses.
 
     Domestic chlorine pricing has come under considerable pressure as chlorine
operating rates have fallen. Chlorine pricing to the key vinyls market segment
fell by approximately 75% from year end 1997 to the fourth quarter of 1998.
 
  Export Chlorine Demand
 
     Chlorine is shipped in the export market in the form of derivative
products, ethylene dichloride ("EDC") and VCM. EDC is produced at the VCM
facility in Deer Park, Texas, and at the OxyMar VCM facility in Ingleside,
Texas, as a raw material in the production of VCM. While EDC is not produced by
                                      F-28
<PAGE>   142
 
the OxyChem Transferred Businesses for the domestic or export market, VCM is
sold on the export market by the OxyMar partnership. The VCM and EDC export
market is critical to maintaining high chlor-alkali operating rates and
consequently, pricing.
 
     Demand for export EDC, shipped almost exclusively to Asia, weakened through
the first half of 1998 causing EDC inventory levels to increase. However, with
reduced production from high-cost producers, demand for U.S. produced product
has increased recently, and inventory levels have fallen. VCM exports declined
YTD, compared to the same period in 1997, by about 235,000 metric tons, or
approximately 30%.
 
  Domestic Liquid Caustic Demand
 
     Demand from the pulp and paper market segment fell in the YTD period due to
a decline in demand for pulp in the Asian markets. A recent modest short-term
increase in the chlorine operating rate caused the over-supply of liquid caustic
to worsen. With the additional supply from industry expansions due on stream in
the first quarter of 1999, the supply/demand situation is expected to worsen
further.
 
     YTD pricing for liquid caustic improved compared to the same period in
1997. As a result of the recent over-supply situation discussed in the preceding
paragraph, liquid caustic pricing has weakened in the fourth quarter of 1998 and
is likely to decline further in future periods as the new capacity comes on
stream.
 
RESULTS OF OPERATIONS
 
  Nine months period ended September 30, 1998 vs. nine months ended September
30, 1997
 
     The OxyChem Transferred Businesses' net income for the first nine months of
1998 was $27.7 million on net sales of $661.0 million, compared with net income
of $51.2 million on net sales of $726.6 million for the same period in 1997.
 
     Gross profit (net sales minus cost of sales) decreased from $133.7 million
for the first nine months of 1997 to $113.3 million for the same period in 1998.
This decrease was due primarily to a 28% decline in PVC margins for the first
nine months of 1998 versus the same period in 1997. This margin decline was due
to PVC revenues falling faster than the major feedstock cost. The large decline
in PVC margins is driven by extremely competitive global markets stemming from
global capacity additions exceeding demand growth which negatively impacted
operating rates and lower pricing. In the chlor-alkali segment, the chlorine
price decline of 31% was partially offset by increased caustic soda price of 35%
and lower energy and raw material cost.
 
     Equity earnings for the OxyMar partnership decreased from a loss of $13.8
million for the first nine months of 1997 to a loss of $25.4 million for the
same period in 1998. The lower earnings are due to a decline of the VCM selling
price of 33%, offset by a reduction in feedstock costs of 33% resulting in a
lower overall margin for VCM. Higher depreciation expense and interest expense
on the 700 million pound per year expansion at OxyMar (the "OxyMar Expansion")
that was completed in 1997 have also reduced equity earnings.
 
     Income tax expense for the first nine months of 1998 was approximately 41%
of income before taxes, as compared with 39% for the same period in 1997. The
increase in the effective tax rate is primarily due to an increase in the state
income tax allocation from Occidental Petroleum Corporation ("OPC"), the
ultimate parent entity of the OxyChem Transferred Business.
 
  1997 vs. 1996
 
     The OxyChem Transferred Businesses' net income for 1997 was $38.7 million
on net sales of $993.6 million, compared with net income of $86.5 million on net
sales of $956.9 million in 1996.
 
     Gross profit decreased from $204.2 million in 1996 to $175.7 million in
1997. PVC resin prices improved by 4% but higher feedstock costs of 10% resulted
in lower PVC margins in 1997 versus 1996.
                                      F-29
<PAGE>   143
 
Margins eroded due to capacity additions in the global market as well as weak
export markets in Southeast Asia. In the chlor-alkali segment, lower overall
margins were the result of a 37% decline in caustic soda prices in 1997 versus
1996, partially offset by the continued strong demand for chlorine related
derivatives which resulted in increased chlorine pricing of 31% in 1997 versus
1996.
 
     Equity earnings from the OxyMar partnership decreased from a loss of $7.6
million in 1996 to a loss of $22.3 million in 1997. The decrease in equity
earnings is due primarily to higher feedstock costs in 1997 of 20% over 1996.
Higher depreciation expense and interest expense due to the OxyMar Expansion
also contributed to the lower earnings.
 
     Selling, general and administrative and other operating expenses in 1997
reflected a charge of $37.5 million for recognition of the impairment of certain
properties, including a write down of property, plant, and equipment at the
Burlington Plant.
 
     Income tax expense was 39% of income before taxes and totaled $24.8 million
and $55.5 million for 1997 and 1996, respectively.
 
  1996 vs. 1995
 
     The OxyChem Transferred Businesses' net income for 1996 was $86.5 million
on net sales of $956.9 million, compared with net income of $177.9 million on
net sales of $1,047.5 million in 1995.
 
     Gross profit decreased from $325.5 million in 1995 to $204.2 million in
1996. The primary driver of this decrease is a 21% decrease in PVC resin price
in 1996 versus 1995 combined with higher feedstock cost increases during the
second half of 1996. This margin erosion during a period of demand growth can be
attributed primarily to substantial capacity additions in both the domestic and
world markets during 1996. In the chlor-alkali segment, a 14% decrease in
caustic soda price in 1996 versus 1995 due to softening demand in key sections
such as aluminum and pulp and paper, coupled with higher energy costs
(electricity and natural gas) were a major cause for the remaining gross profit
decrease.
 
     Equity earnings from the OxyMar partnership decreased from income of $14.2
million in 1995 to a loss of $7.6 million in 1996. The lower earnings are due to
decreased export pricing of 27% in 1996 versus 1995 coupled with a 17% decline
in domestic pricing for the same time period, partially offset by a reduction in
feedstock costs of 11% resulting in a 43% decrease in margin for VCM in 1996
versus 1995.
 
     Income tax expense was approximately 39% of income before taxes and totaled
$55.5 million and $113.4 million for 1996 and 1995, respectively.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  September 1998 and September 1997
 
     During the nine months ended September 30, 1998, the OxyChem Transferred
Businesses generated $77.1 million of net cash provided from operating
activities compared to $74.1 million during the same period in 1997. The YTD
1998 earnings before non-cash charges were $5.6 million lower than 1997.
 
     Working capital (accounts receivable plus inventory less accounts payable)
increased by $4.7 million for the first nine months of 1998 primarily due to
increased trade receivables. Working capital increased by $14.2 million for the
same period in 1997 primarily due to lower energy and raw material payables
partially offset by decreased caustic soda inventories.
 
     Investing activity consists of spending on maintenance, environmental
health and safety, capital improvement and expansion projects at the OxyChem
Transferred Businesses' various manufacturing sites. Capital expenditures
decreased from $75.9 million for the nine months ended September 30, 1997, to
$49.5 million for the same period in 1998 primarily due to 1997 spending on a
450 million
 
                                      F-30
<PAGE>   144
 
pounds-per-year expansion at the Pasadena, Texas, PVC plant, increasing capacity
at the Pasadena site to 1.8 billion pounds of PVC, partially offset by 1998
spending on the construction of a compound plant at the Pasadena site. Capital
spending is projected to be approximately $62.0 million for all of 1998. An
additional $17.5 million of net cash used by investing activities YTD resulted
from a loan to the OxyMar partnership
 
     Financing activities reflect the net cash provided by operating activities
less investing activities. Financing activities in the first nine months of 1998
reflected net cash used of $10.1 million compared to net cash provided of $1.8
million for the same period in 1997. 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 as decreases or
increases, respectively, in invested capital.
 
  1997, 1996 and 1995
 
     Net cash provided by operating activities was $117.0 million for 1997
compared to $146.0 million for 1996 and $213.2 million for 1995. The 1997
earnings before non-cash charges were $11.5 million higher than 1996 and 1996
earnings before noncash charges were $27.5 million lower than 1995.
 
     Working capital increased by $16.1 million during 1997 primarily due to
higher inventories and increased trade receivables due to increased export
sales. Working capital decreased by $20.8 million in 1996 and $3.3 million in
1995. The 1996 decrease was primarily due to lower trade receivables resulting
from lower export prices and accelerated collections of certain accounts. The
1995 decrease was primarily due to higher trade payables partially offset by
increased inventories.
 
     Investing activity increased in each of 1996 and 1997 from $55.4 million in
1995 to $102.0 million in 1996 and to $122.7 million in 1997. The 1997 increase
was primarily due to capital spending on a capacity expansion/modernization
project at the Houston Chemical Complex Chlor-Alkali facilities in Deer Park,
Texas. The 1996 increase was primarily due to spending on the PVC capacity
expansion at the Pasadena, Texas, facility.
 
     Financing activities in 1997 reflected net cash provided of $5.7 million
compared to net cash used of $44,0 million in 1996 and $57.8 million in each of
1996 and 1995, respectively. These decreases in invested capital reflect OPC's
use of its centralized cash management system to sweep the excess of cash
provided by operating activities over capital spending.
 
     OxyChem has not yet prepared its capital budgets for 1999 or beyond.
However, OxyChem does not expect capital expenditures to exceed materially
capital spending in prior years. Capital expenditures for the nine months ended
September 30, 1998, were $49.5 million. Capital expenditures were $122.7 million
in 1997, $102.0 million in 1996 and $55.4 million in 1995. It is anticipated
that internally generated cash flow, together with the credit facility referred
to below, will be sufficient to fund operations and capital expenditures.
 
     As part of the Joint Venture Transactions, OPC will provide to the PVC
partnership a credit facility for approximately 150,000,000, $110,000,000 of
which is expected to be available on a revolving basis and $36,000,000 of which
is to be repaid from a portion of the partnership's cashflows.
 
MARKET RISK
 
     The market risk exposures of OxyChem's Transferred Businesses relate
primarily to commodity prices. During the periods described above, OxyChem did
not enter into futures contracts or engage in activities using complex or highly
leveraged instruments in respect of OxyChem's Transferred Businesses.
 
  Year 2000 Issue
 
     OPC's effort to address Year 2000 (Y2K) issues, which includes the OxyChem
Transferred Businesses, began in 1997. In addressing the issues OPC has employed
a five-step process consisting of:
 
                                      F-31
<PAGE>   145
 
1) conducting a company-wide inventory, 2) assessing Y2K compliance, 3)
remediating non-compliant software and hardware, particularly hardware that
employs embedded chips such as process controls, 4) testing remediated hardware
and software, and 5) certifying Y2K compliance.
 
     Personnel from operations, functional disciplines, as well as information
technology are involved in the process. Outside consultants have also been
retained to participate in the inventory and assessment process. A Y2K
corporate-level manager was appointed to oversee and provide consistency to the
overall process, provide support resources on a company-wide basis and minimize
duplication of efforts. In addition, a committee of senior corporate executives
provides oversight through an extensive monthly status at each board meeting.
 
     Inventory and assessment activities are estimated at approximately 85
percent complete. This data is continuously updated as new information becomes
available and this is expected to continue throughout the Y2K effort. Overall
remediation efforts are estimated at approximately 35 percent complete. The
coincidental replacement of several major existing systems is well under way;
these efforts began before the Y2K efforts were initiated. As a result, the
timing for completion of these projects has not been accelerated as a result of
Y2K issues. These new systems will allow OPC to discontinue use of existing
systems prior to January 1, 2000.
 
     Cost for Y2K efforts are not being accumulated separately. Much of the cost
is being accounted for as part of normal operating budgets. Overall, the costs
are estimated to be approximately $2.2 million. Most of the cost is associated
with the remediation of various process control and field systems (systems that
utilize embedded computer chip technology). Due to the nature of these devices
and to minimize the impact on normal operations the remediation process will
continue until mid 1999.
 
     The risks associated with the Y2K issue can be substantial from the
standpoint of reliance on third parties. Communication with customers, suppliers
and equity partners to determine the extent of their Y2K efforts, including
selected site visits, is an integral part of the program. OPC, like most
companies, is reliant on third parties for a wide variety of goods and
services -- from raw materials to electricity. OPC's efforts include addressing
the "supply chain" issues to minimize the potential impact of a major supplier
(or customer) experiencing a Y2K problem that would adversely affect OPC.
 
     Because of these company-wide efforts, OPC believes that appropriate
actions have been taken to minimize the risk to its operations and financial
condition.
 
     Contingency plans that address a reasonable likely worst case scenario are
currently being developed. These plans will address the key systems and third
parties that present potential significant risk. The plans will analyze the
strategies and resources necessary to restore operations in the unlikely event
that an interruption does occur. The plans will also outline a recovery program
detailing the necessary participants, processes and equipment needed to restore
operations. Contingency plans are expected to be finalized during the third
quarter of 1999.
 
  Safe Harbor Statement Regarding Outlook and Forward-Looking Information
 
     Portions of this Management's Discussion and Analysis include
forward-looking statements, including those identified by the words "believes,"
"anticipates," "expects" and similar expressions. OxyChem has based these
forward-looking statements on its current expectations and projections about
future events. These forward-looking statements are subject to risks,
uncertainties, and assumptions about the OxyChem Transferred Businesses,
including, among other things:
 
     - global commodity pricing fluctuations;
 
     - competitive pricing pressures;
 
     - higher than expected costs, including feedstocks;
 
     - the supply and demand considerations for its products;
 
     - any general economic recession domestically or internationally; and
 
     - not successfully completing any expansion, capital expenditure,
       acquisition or divestiture.

     Neither OxyChem nor Geon undertake any obligation to publicly update or
revise any forward-looking statements, whether as a result of new information,
future events or otherwise. In light of these risks, uncertainties and
assumptions, the forward-looking events discussed in this management's
discussion and analysis might not occur.

A.  BASIS OF PRESENTATION AND DESCRIPTION OF THE PVC BUSINESS
 
     In June 1998, The Geon Company ("Geon") and Occidental Chemical Corporation
("OxyChem"), a subsidiary of Occidental Petroleum Corporation, announced the
intention to form a business (the "PVC Partnership") that produces and markets
polyvinyl chloride ("PVC") suspension and mass resins and vinyl chloride monomer
("VCM"). The PVC Partnership will be owned 76% by OxyChem and 24% by Geon. In
December 1998, the parties announced that a Master Transaction Agreement
("Agreement") had been signed.
 
     Under the Agreement, Geon will contribute to the PVC Partnership certain
assets and liabilities of Geon's PVC suspension and mass resin business (the
"Geon PVC Business'), including five PVC plants and one VCM plant. The PVC
Partnership will assume the obligations of Geon under the lease of the VCM
production facility located in LaPorte, Texas, as well as industrial revenue
bond debt related to that facility. Geon will retain certain accounts
receivable, inventories, and accrued liabilities after formation of the PVC
Partnership.
 
     Under the Agreement, OxyChem will contribute certain PVC, VCM, and
chlor-alkali plants, together with certain related assets. The PVC Partnership
will assume OxyChem's 50% interest in debt obligations of its OxyMar joint
venture.
 
     Under the Agreement, Geon and OxyChem will also form a separate partnership
that will operate a powder/dry blend compounding business. In addition, OxyChem
will sell to Geon its specialty pellet compound business.
 
     Once the PVC Partnership is formed, Geon will purchase its PVC and VCM
requirements, subject to certain limitations, from the PVC Partnership under
long-term supply agreements. The initial term of the agreements are through the
year 2013, with two five year renewal options thereafter.
 
     The proposed transactions with OxyChem are subject to a number of
conditions, including the execution of definitive documents, approval of the
respective boards of directors and Geon shareholders.
 
     The accompanying financial statements include the operating results,
operating assets and liabilities, and cash flows directly related to the Geon
PVC Business, which is currently owned by Geon and will be contributed to the
PVC Partnership. These financial statements are presented on a going concern
basis and include only the historical net assets and the historical results of
operations that are directly related to the Geon PVC Business. The Geon PVC
Business is a producer and marketer of PVC resins and VCM, an intermediate
precursor to PVC. The Geon PVC Business operates primarily in the United States
and Canada in one business segment.
 
     The Geon PVC Business shares certain manufacturing and warehousing
facilities with the other businesses of Geon. The Geon PVC Business records its
sales and expenses separately and distinctly from the other Geon businesses.
Geon provided certain support activities such as administration, legal, finance,
treasury, business development, information systems, accounting, human
resources, and risk management to the Geon PVC Business. The cost of such
activities has been charged to the Geon PVC Business and totaled $18.7, $18.5,
and $16.7 in 1997, 1996 and 1995, respectively. In the opinion of management,
charges and allocations have been determined on a reasonable basis (primarily on
a proportional cost basis) and reflect the expenses of the Geon PVC Business as
operated by Geon; however, they are not necessarily indicative of the level of
expenses which might have been incurred

had the Geon PVC Business been operating as a stand-alone entity. Consequently,
the financial position, results of operations, and cash flows may not be
indicative of what would have been reported if the Geon PVC Business had been a
separate, stand-alone entity during the period presented. In addition, Geon has
controlled on a centralized basis all cash receipts and disbursements received
or made by the Geon PVC Business. The net results of such transactions are
included in the balance sheet as invested capital.
 
     The Geon PVC Business sells PVC and VCM to affiliated business units of
Geon for the manufacture of compounds and other PVC products. Such sales have
been reflected at internally calculated transfer prices which approximate the
market price for similar transactions with third parties. These sales totaled
$181.2, $153.8, and $150.4 in 1997, 1996, and 1995 respectively, and the amounts
due from Geon related to these sales are included in invested capital in the
applicable year.
 
B.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Revenue Recognition
 
     Geon recognizes revenues from product sales at the point of passage of
title, which is at the time of shipment.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Trade Receivables
 
     The Geon PVC Business participated in an agreement between Geon and a bank
to sell an undivided interest in certain trade accounts receivable. The
outstanding amount sold under the program attributable to the Geon PVC Business
and included in the net trade accounts receivable presented in the balance
sheets was $26.4 and $27.7 at December 31, 1997 and 1996 respectively.
 
     Trade accounts receivable presented in the balance sheets is net of an
allowance for doubtful accounts of $.1 at December 31, 1997 and 1996.
 
  Inventories
 
     Inventories are valued at the lower of cost or market. Cost is determined
by the last-in, first-out (LIFO) cost method. Inventories not valued by the LIFO
method are valued principally by the average cost method.

  Property, Plant and Equipment
 
     Property, plant, and equipment is stated at cost, net of depreciation and
amortization computed principally using the straight-line method over the
estimated useful life of the asset, ranging from 3 to 15 years for machinery and
equipment and up to 40 years for buildings. Property, plant, and equipment is
generally depreciated on accelerated methods for income tax purposes. Repairs
and maintenance costs are expensed as incurred, except for costs associated with
periodic plant turnaround costs which are deferred and amortized over
approximately two years, the period benefited. Amortization expense related to
deferred plant turnaround costs totaled $4.1, $3.8, and $3.9 in 1997, 1996, and
1995, respectively. Unamortized turnaround costs were $1.9 and $6.4 at December
31, 1997 and 1996, respectively. Property, plant, and equipment consists of the

     Long lived assets are reviewed for impairment. Impairment is recognized
when events or changes in circumstances indicate that the carrying amount of the
asset or related group of assets may not be recoverable. If the expected future
undiscounted cash flows are less than the carrying amount of the asset, an
impairment loss is recognized at that time. Measurement of impairment may be
based upon appraisal, market value of similar assets, or discounted cash flows.
 
  Accounts Payable
 
     Accounts payable are managed by Geon on a centralized basis, and,
accordingly, amounts attributable to the individual business units cannot be
specifically determined. The amount of accounts payable included in these

  Environmental Remediation Costs
 
     Expenditures related to investigation and remediation of environmental
contamination, which include operating facilities and waste disposal sites, are
expensed and accrued by Geon when it is probable that a liability has been
incurred and the amount of the liability can be reasonably estimated.
Environmental expense (credit) for 1997, 1996, and 1995 was $0.5, $(1.6), and
$(1.0), respectively. The credits to expense in 1996 and 1995 reflect reductions
in the accrual for environmental liabilities based upon favorable remediation
experience on specific projects and management's estimates for similar future
expenditures. Such accrued liabilities are exclusive of claims against
third-parties and are not discounted. Expenditures related to environmental
remediation are charged against the accrual.
 
     Management believes that compliance with current governmental regulations
at all levels will not have a material adverse effect on its financial
condition, results of operations, or cash flows. Based on estimates prepared by
Geon's environmental engineers and consultants, the Geon PVC Business had
accruals totaling $5.0 and $4.6 at December 31, 1997 and 1996, respectively, to
cover probable future environmental expenditures related to previous
contamination at its facilities. The accrual represents management's best
estimate for the remaining remediation costs based upon information and
technology currently available. Depending on the results of future testing and
the ultimate remediation alternative undertaken at the sites, it is possible
that costs could be more than those recorded by as much as $1.5 at December 31,
1997. Management's estimate of the liability may be revised as new regulations,
technologies, or additional information is obtained.
 
  Income Taxes
 
     Earnings of the Geon PVC Business have been included in the income tax
returns filed by Geon. Income taxes have been allocated to the Geon PVC Business
based on approximate applicable statutory tax rates. Such amounts do not
materially differ from the income tax expense which would result if such income
taxes had been computed on a separate return basis. The effective income tax
rate was 38.8%, 38.6%, and 39.0% for the years ended December 31, 1997, 1996,
and 1995, respectively. Liabilities for current and/or deferred income taxes
have been and remain the responsibility of Geon and, accordingly, have been
included in the balance sheet as invested capital.

  Foreign Currency Translation
 
     Income statement items are translated at average currency exchange rates.
Translation gains and losses are included in determining net income. All balance
sheet accounts of foreign divisions are translated to the reporting currency at
the current exchange rate at the end of the period. The resulting translation
adjustment is recorded as part of invested capital.
 
  Research and Development
 
     Research and development costs are expensed as incurred. Amounts expensed
directly associated with the Geon PVC Businesses approximated $8.2, $9.8, and
$9.6 in 1997, 1996, and 1995, respectively.
 
C. LEASES
 
     The Geon PVC Business leases certain warehouse space, a production
facility, machinery and equipment, automobiles, and railcars under operating

     The foregoing information includes the lease of a VCM production facility
and related equipment located in LaPorte, Texas, under an operating lease that
expires in 2001. Under the terms of the lease, the Geon PVC Business has options
to renew the lease for five one-year periods and may purchase the VCM facility
and equipment at the then-fair value at any time during the lease term. The
lease provides for a substantial residual value guarantee of approximately $140
at December 31, 1997, by the Geon PVC Business at the termination of the lease.
In 1996, the lease agreement was amended to include additional equipment for
which the Geon PVC Business has assumed an additional $45 construction
performance obligation. Construction was completed in October 1998 and lease
payments began thereafter.

E.  PENSION AND OTHER POSTRETIREMENT BENEFITS
 
     Substantially all employees of the Geon PVC Business are covered by defined
benefit pension plans sponsored by Geon. Benefits under the plan are based on
compensation and length-of-service. Annual contributions to the plans are
sufficient to satisfy legal requirements. Geon also maintains a voluntary
retirement savings plan covering most employees of the Geon PVC Business under
which eligible employees can receive matching Geon contributions.
 
     In addition, eligible employees of the Geon PVC Business are covered by
certain unfunded defined benefit postretirement plans that provide certain
health care and life insurance benefits.
 
     For purposes of these separate financial statements, the Geon PVC Business
is considered to be participating in multiemployer pension and postretirement
benefit plans. Geon has allocated costs related to these plans to the Geon PVC
Business based on the census data of participants covered by the plans as of
January 1, 1997. Expenses related to these plans and included in the

F.  YEAR 2000 (Y2K) ISSUE
 
     State of Readiness
 
     Since 1997, Geon has been actively involved in surveying, assessing, and
correcting Y2K problems with its information technology structure. Geon's
information technology structure includes, among others, commercial business
information systems, manufacturing information systems, desktop computing
networks, and data and communication networks. Geon implemented a new integrated
commercial business information system in 1997 which is Y2K compliant and will
support approximately 90% of the current operations. Following the assessment of
its information technology structure, Geon identified its

systems that it believed may be vulnerable to Y2K failures and established a
program to address Y2K issues.
 
     Geon's Y2K efforts are being carried out by Geon's Y2K compliance team
under the leadership of the Manager of Technical Support. The Manager of
Technical Support has assembled a group of seven individuals to oversee the
implementation of Geon's Y2K program and has appointed a person at each of
Geon's facilities, including those newly acquired, to address Y2K issues. The
Y2K compliance team maintains a reporting structure to ensure that progress is
made on Y2K issues and to ensure the reliability of risk and cost estimates
relating to Y2K problems.
 
     The most critical non-information technology systems, such as automated
process control equipment, are relatively new and are being upgraded and
maintained with the help of Geon's various suppliers. To date, Geon's
investigation of these systems has not revealed any Y2K problems; however,
investigation in this area continues.
 
     In February 1997, Geon completed the installation of a new integrated
commercial business information system which is Y2K compliant and will support
approximately 90% of Geon's current operations. The purchase and initial
installation of Geon's new commercial business information system cost
approximately $20 million. Currently, Geon is operating one older information
system which Geon has remediated. As a result of the installation of the new
system and its remediation efforts, Geon has competed all of its Y2K work with
respect to its commercial business information systems. Geon is also in the
process of remediating all of its technical infrastructure. The most critical
non-information technology systems include automated process control equipment
and equipment containing embedded chips. These systems are relatively new and
are being upgraded and maintained with the help of Geon's various suppliers.
 
     In addition to internal resources, Geon is utilizing external resources to
implement its Y2K program and to ensure that its risk and cost estimates are
reliable. Geon has contracted with outside consultants to verify Geon's
assessment of its Y2K problems and to assist it with remediation efforts.
 
     Geon relies significantly upon third parties in the operation of its
business. As a result, as part of Geon's Y2K program, the purchasing and
production control department of each operating unit has made, and is making,
efforts to determine and assess the Y2K compliance status of third parties with
which Geon does business. In particular, throughout 1998, Geon contacted and
sent questionnaires to all of its raw material suppliers to obtain information
relating to the status of such suppliers with respect to Y2K issues. Geon
received assurances from 75% of its raw material suppliers that they are or
would be Y2K compliant by July 1999. Geon has maintained ongoing correspondence
with its suppliers regarding Y2K issues and placed particular emphasis on
determining the Y2K readiness of its critical suppliers.
 
     Due to the uncertainties associated with Y2K problems, Geon is in the
process of developing contingency plans in the event that its business or
operations are disrupted January 1, 2000. As part of this plan, Geon expects to
adjust its inventory levels and mix of products and raw materials consistent
with good business practice based upon the risks that Geon believes exist. In
addition, Geon expects to develop a plan that outlines how one facility can
compensate for any disruption at another facility due to Y2K problems.

     Completion
 
     Geon's Y2K compliance team expects Geon's internal systems and processes to
be Y2K compliant by July 1999.
 
     Costs
 
     Geon anticipates incurring total out-of-pocket expenditures of
approximately $.75 million on Y2K issues. To date, Geon has incurred
out-of-pocket cost of approximately $.3 million on Y2K issues, plus internal
personnel time included in the scope of normal operations. Approximately 85% of
these funds have been used in connection with remediation, and 15% of these
funds have been used to replace portions of the information technology
structure. The funds used by Geon to address its Y2K problems are from the
general business budget, and all such costs are expensed as incurred.
 
     Risks
 
     If Geon's suppliers and customers are not Y2K compliant by January 1, 2000,
such noncompliance could materially affect Geon's business, results of
operations, and financial condition. Geon may experience some random or
unforeseen supply chain disruptions that may affect its ability to produce and
distribute key products. In addition, Geon's business may be disrupted if a
significant number of its customers are unable to pay for product supplied to
them by Geon. Geon's worst case scenario is the inability of Geon to receive raw
materials or remove products from its facilities. In order for Y2K problems to
have a material effect on Geon, Geon believes that more than one of its
facilities would have to experience significant Y2K problems.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                                   UNAUDITED
 
NOTE A
 
     The accompanying unaudited condensed financial statements of The Geon
Company's ("Geon") PVC suspension and mass resin business, which is being
contributed to a joint venture with Occidental Chemical Corporation ("OxyChem"),
a subsidiary of Occidental Petroleum Corporation, (the "Geon PVC Business") have
been prepared in accordance with generally accepted accounting principles for
interim financial information. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
financial presentation have been included. Operating results for the nine month
periods ended September 30, 1998 and 1997 are not necessarily indicative of the
results that may be expected for the year ending December 31, 1998 or in the
future.
 
     In June 1998, Geon announced that a non-binding letter of intent had been
signed to enter into transactions with OxyChem. In December 1998, the parties
announced that a Master Transaction Agreement had been signed. The proposed
transactions would result in (i) the creation of a joint venture, comprised of
the PVC suspension and mass resin businesses and related supporting operations
of both companies, which would be 76 percent owned by OxyChem and 24 percent by
Geon; (ii) the creation of a joint venture, comprised of the powder/dry blend
compound business of both companies, which would be 90 percent owned by Geon and
10 percent owned by OxyChem; and (iii) the acquisition by Geon of OxyChem's
vinyl compound, film and pellet businesses located at Burlington, New Jersey,
and Pasadena, Texas. The proposed transactions with OxyChem are subject to a
number of conditions, including the execution of final documents, approval of
the board of directors of each company and the Geon shareholders.
 
NOTE B
 
     The accompanying financial statements include the operating results,
operating assets and liabilities, and cash flows of the Geon PVC Business, which
is currently owned by Geon. These financial statements are presented on a going
concern basis and include only the historical net assets and the historical
results of operations and cash flows that are directly related to the Geon PVC
Business. The Geon PVC Business is a producer and marketer of polyvinyl chloride
("PVC") suspension and mass resins and vinyl chloride monomer ("VCM"), an
intermediate precursor to PVC. The Geon PVC Business operates primarily in the
United States and Canada in one business segment. Geon has controlled, on a
centralized basis, all cash receipts and disbursements received or made by the
Geon PVC Business. The net results of such transactions are included in the
balance sheet as invested capital.
 
   
     The Geon PVC Business shares certain manufacturing and warehousing
facilities with the other businesses of Geon. The Geon PVC Business records its
sales and expenses separately and distinctly from the other Geon businesses.
Geon provided certain support activities such as administration, legal, finance,
treasury, business development, information systems, accounting, human
resources, and risk management to the Geon PVC Business. The cost of such
activities has been charged to the Geon PVC Business and totaled $15.3 and $14.5
for the nine month period ended September 30, 1998 and 1997, respectively. In
the opinion of management, charges and allocations have been determined on a
reasonable basis (primarily on a proportional cost basis) and reflect the
expenses of the Geon PVC Business as operated by Geon; however, they are not
necessarily indicative of the level of expenses which might have been incurred
had the Geon PVC Business been operating as a stand-alone entity. Consequently,
the financial position, results of operations, and cash flows may not be
indicative of what would have been reported if the Geon PVC Business had been a
separate, stand-alone entity during the period presented. In addition, Geon has
controlled on a centralized basis all cash receipts and disburse-

ments received or made by the Geon PVC Business. The net results of such
transactions are included in the balance sheet as invested capital.
    
 
   
     The Geon PVC Business sells PVC and VCM to affiliated business units of
Geon for the manufacture of compounds and other PVC products. Such sales have
been reflected at internally calculated transfer prices which approximate the
market price for similar transactions with third parties. These sales totaled
$105.7 and $138.9 for the nine month period ended September 30, 1998 and 1997,
respectively, and the amounts due from Geon related to these sales are included
in invested capital in the applicable period.
    
 
NOTE C
 
     Expenditures related to the investigation and remediation of environmental
contamination, which include operating facilities and waste disposal sites, are
expensed and accrued by the Geon PVC Business when it is probable that a
liability has been incurred and the amount of the liability can be reasonably
estimated. Such accrued liabilities are exclusive of claims against
third-parties (except where payment has been received or the amount of liability
or contribution by such other parties, including insurance companies, has been
agreed) and are not discounted. In general, expenditures related to
environmental remediation are charged against the accrual.
 
     Management believes that compliance with current governmental regulations
at all levels will not have a material adverse effect on its financial
condition, results of operations, or cash flows. Based on estimates prepared by
Geon's environmental engineers and consultants, the Geon PVC Business at
September 30, 1998, had accruals totaling $2.2 million to cover probable future
environmental expenditures related to previous contamination. The accrual
represents management's best estimate for the remaining remediation costs based
upon information and technology currently available. Depending on the results of
future testing and the ultimate remediation alternative undertaken at the sites,
it is possible that costs could be more than those recorded at September 30,
1998, by as much as $3.4 million. The estimate of the liability may be revised
as new regulations, technologies, or additional information is obtained.

     The decrease in the LIFO reserve is primarily the result of significant
reductions in the price of ethylene and chlorine, key raw materials used in the
production of PVC resins.
 
NOTE E
 
     The Geon PVC Business participated in an agreement between Geon and a bank
to sell an undivided interest in certain trade accounts receivable. The
outstanding amount sold under the program attributable to the Geon PVC Business
and included in the net trade accounts receivable presented in the balance sheet
was $35.7 at September 30, 1998.

     In March 1998, Geon announced an agreement with Bayer Corporation under
which Bayer will utilize a pipeline to transport anhydrous chlorine (HCl) from
its plant in Baytown, Texas, to Geon's VCM plant in LaPorte, Texas. Geon has
constructed an oxychlorination facility at LaPorte which will convert the HCI
for use in making VCM at its LaPorte facility. Operation of the pipeline and
related facilities commenced early in the fourth quarter of 1998.
 
NOTE G
 
     State of Readiness
 
     Since 1997, Geon has been actively involved in surveying, assessing, and
correcting Year 2000 ("Y2K") problems with its information technology structure.
Geon's information technology structure includes, among others, commercial
business information systems, manufacturing information systems, desktop
computing networks, and data and communication networks. Geon implemented a new
integrated commercial business information system in 1997 which is Y2K compliant
and will support approximately 90% of the current operations. Following the
assessment of its information technology structure, Geon identified its systems
that it believed may be vulnerable to Y2K failures and established a program to
address Y2K issues.
 
     Geon's Y2K efforts are being carried out by Geon's Y2K compliance team
under the leadership of the Manager of Technical Support. The Manager of
Technical Support has assembled a group of seven individuals to oversee the
implementation of Geon's Y2K program and has appointed a person at each of
Geon's facilities, including those newly acquired, to address Y2K issues. The
Y2K compliance team maintains a reporting structure to ensure that progress is
made on Y2K issues and to ensure the reliability of risk and cost estimates
relating to Y2K problems.
 
     The most critical non-information technology systems, such as automated
process control equipment, are relatively new and are being upgraded and
maintained with the help of Geon's various suppliers. To date, Geon's
investigation of these systems has not revealed any Y2K problems; however,
investigation in this area continues.
 
     In February 1997, Geon completed the installation of a new integrated
commercial business information system which is Y2K compliant and will support
approximately 90% of Geon's current operations. The purchase and initial
installation of Geon's new commercial business information system cost
approximately $20 million. Currently, Geon is operating one older information
system which Geon has remediated. As a result of the installation of the new
system and its remediation efforts, Geon has competed all of its Y2K work with
respect to its commercial business information systems. Geon is also in the
process of remediating all of its technical infrastructure. The most critical
non-information technology systems include automated process control equipment
and equipment containing embedded chips. These systems are relatively new and
are being upgraded and maintained with the help of Geon's various suppliers.
 
     In addition to internal resources, Geon is utilizing external resources to
implement its Y2K program and to ensure that its risk and cost estimates are
reliable. Geon has contracted with outside consultants to verify Geon's
assessment of its Y2K problems and to assist it with remediation efforts.
 
     Geon relies significantly upon third parties in the operation of its
business. As a result, as part of Geon's Y2K program, the purchasing and
production control department of each operating unit has made, and is making,
efforts to determine and assess the Y2K compliance status of third parties with
which Geon does business. In particular, throughout 1998, Geon contacted and
sent questionnaires to

all of its raw material suppliers to obtain information relating to the status
of such suppliers with respect to Y2K issues. Geon received assurances from 75%
of its raw material suppliers that they are or would be Y2K compliant by July
1999. Geon has maintained ongoing correspondence with its suppliers regarding
Y2K issues and placed particular emphasis on determining the Y2K readiness of
its critical suppliers.
 
     Due to the uncertainties associated with Y2K problems, Geon is in the
process of developing contingency plans in the event that its business or
operations are disrupted January 1, 2000. As part of this plan, Geon expects to
adjust its inventory levels and mix of products and raw materials consistent
with good business practice based upon the risks that Geon believes exist. In
addition, Geon expects to develop a plan that outlines how one facility can
compensate for any disruption at another facility due to Y2K problems.
 
     Completion
 
     Geon's Y2K compliance team expects Geon's internal systems and processes to
be Y2K compliant by July 1999.
 
     Costs
 
     Geon anticipates incurring total out-of-pocket expenditures of
approximately $.75 million on Y2K issues. To date, Geon has incurred
out-of-pocket cost of approximately $.3 million on Y2K issues, plus internal
personnel time included in the scope of normal operations. Approximately 85% of
these funds have been used in connection with remediation, and 15% of these
funds have been used to replace portions of the information technology
structure. The funds used by Geon to address its Y2K problems are from the
general business budget, and all such costs are expensed as incurred.
 
     Risks
 
     If Geon's suppliers and customers are not Y2K compliant by January 1, 2000,
such noncompliance could materially affect Geon's business, results of
operations, and financial condition. Geon may experience some random or
unforeseen supply chain disruptions that may affect its ability to produce and
distribute key products. In addition, Geon's business may be disrupted if a
significant number of its customers are unable to pay for product supplied to
them by Geon. Geon's worst case scenario is the inability of Geon to receive raw
materials or remove products from its facilities. In order for Y2K problems to
have a material effect on Geon, Geon believes that more than one of its
facilities would have to experience significant Y2K problems.

                         REPORT OF INDEPENDENT AUDITORS
    
 
   
TO THE STOCKHOLDERS AND BOARD OF DIRECTORS OF THE GEON COMPANY:
    
 
   
     We have audited the accompanying consolidated balance sheets of The Geon
Company and subsidiaries as of December 31, 1997, and 1996, and the related
consolidated statements of income, stockholders' equity, and cash flows for each
of the three years in the period ended December 31, 1997. These financial
statements, which appear on pages F-54, F-56, and F-58 through F-71, are the
responsibility of the Company'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 consolidated financial position of The Geon
Company and subsidiaries at December 31, 1997, and 1996, and the consolidated
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1997, in conformity with generally accepted
accounting principles.

                 MANAGEMENT'S ANALYSIS -- STATEMENTS OF INCOME
 
     In 1997, the Company achieved new records in both resin and compound
shipments. Operating income, before a special charge for employee separation
costs, increased $37.1 million, or 124% over 1996 despite lower industry resin
margins (selling prices less the cost of key raw materials) in 1997 versus last
year. This improvement is the result of the Company's efforts to grow and expand
its value-added market segments, which consist of compounds and specialty
dispersion resins. In addition, the Company has further reduced the material and
operating costs of its resin operations with the April 1996 startup of its
LaPorte, Texas, vinyl chloride monomer (VCM) plant facility expansion and other
improvements. The acquisition of Synergistics Industries Limited (Synergistics)
was completed and became part of Geon's consolidated operations effective
October 31, 1997. While Synergistics had a strong two months of operations, its
impact on 1997 earnings was not significant, as a result of accounting
adjustments. We are confident that Synergistics will be accretive to earnings in
1998.
 
   
     1997 INDUSTRY CONDITIONS -- The Company believes that, based on the Society
of Plastics Industry's (SPI) December 1997 data, North American (U.S. and
Canada) producer shipments of polyvinyl chloride (PVC) resins (including
exports) are estimated to have increased 6% over 1996. In 1997, based on SPI
data, export shipments are estimated to have increased 33% over 1996. Domestic
shipments increased approximately 3% over last year.
    
 
   
     Capacity utilization (shipments/capacity) for North America is estimated at
94% of effective capacity (88% of nameplate) in 1997. North American capacity
increased 7% over 1996.
    
 
     The Company believes that average industry operating spreads for the
largest PVC resin market applications decreased approximately 1.0 cent per pound
in 1997 as compared with 1996. This decrease was the result of higher average
feedstock costs of approximately 20%, only partially offset by higher average
selling prices. In 1997, ethylene costs on average were approximately 15% higher
than in 1996. Average chlorine costs increased approximately one-third over 1996
levels.
 
   
     1997 RESULTS OF OPERATIONS -- The Company had sales of $1.25 billion for
1997, an increase of 9% from 1996. The Company's unit shipment growth exceeded
the industry with increases in resin and compound of 7% and 17%, respectively.
The compound shipments increased 7%, excluding Synergistics. The Company's
export shipments in 1997 of both resin and VCM decreased from 1996 levels 24%
and 88%, respectively.
    
 
     In 1997, the Company had operating income of $52 million and net income of
$22.5 million. Despite improved earnings, the Company continues to focus on cost
reductions and recorded a second-quarter pre-tax charge of $15 million ($9.2
million after tax) to cover costs associated with a voluntary early retirement
program. Construction was completed and a jointly owned chlor-alkali plant
commenced operations in November 1997. The plant will produce approximately
one-third of Geon's chlorine requirements at producer economics. During the
year, the Company further improved its resin production per unit of capacity and
compound manufacturing output per line hour. Further, the Company is pursuing
increased revenues in value-added market segments, which resulted in the
acquisition of Synergistics for approximately $86.5 million. In 1997,
employment, excluding the Synergistics acquisition, declined by 8%.
 
   
     1996 INDUSTRY CONDITIONS -- Total shipments were 11% higher than in 1995.
The effective capacity utilization rate in 1996 was 95%, or 1% higher than in
1995. The 1996 average resin spreads were approximately 6.5 cents per pound
below 1995.
    
 
   
     1996 RESULTS OF OPERATIONS -- The Company had sales of $1.14 billion for
1996, a decrease of 10% from 1995. The Company's unit shipment growth exceeded
the industry with increases in resin and compound of 14% and 11%, respectively.
The unit sales growth was more than offset by decreases in resin selling prices.
Also, the VCM volume being exported substantially decreased from 1995.
    
 
     In 1996, the Company had operating income of $29.9 million, down from
$127.2 million in 1995, excluding the 1995 special charge primarily associated
with the compound manufacturing reconfiguration. This decline in operating
income primarily resulted from the severe drop in industry resin spreads. The
lower 1996 resin spreads, as compared with 1995, decreased resin operating
income by approximately $110 million. During 1996, employment levels declined by
2%.

                    MANAGEMENT'S ANALYSIS -- BALANCE SHEETS
 
     The consolidated balance sheet at December 31, 1997, reflects the solid
financial position of The Geon Company.
 
   
     ASSETS -- Total assets increased by 18% to $872.9 million at December 31,
1997. The change in assets is primarily related to the acquisition of
Synergistics. Other assets include the intangibles associated with the
Synergistics acquisition and the Company's equity investments. Included in the
equity investments is the Company's 50% participation in a chlor-alkali joint
venture and an Australian joint venture with Orica Limited (formerly ICI
Australia). The Australian joint venture commenced operations in August 1997,
with the Company contributing most of the assets of its Australian PVC
subsidiary in exchange for a 37% ownership interest.
    
 
   
     LIABILITIES AND EQUITY -- The Synergistics acquisition was funded with a
variable-rate short-term credit facility. At December 31, 1997, $83.9 million
was outstanding under this agreement. The Company intends to refinance the
Synergistics short-term credit facility with long-term debt prior to the
expiration of this credit agreement in June 1998. At December 31, 1997, the
Company had outstanding $125 million in debentures issued in 1995 and maturing
in 10 and 20 years from issuance. The debentures have received investment-grade
credit ratings. In addition, the Company has available unsecured lines of credit
and overdraft facilities totaling $193 million. Other non-current liabilities
include most of the Company's accrued environmental liabilities, including those
associated with Synergistics, as well as pension accruals. The stronger U.S.
dollar against the Canadian and Australian dollar resulted in unrecognized
translation losses included in other equity of $8.3 million. In 1997, the
Company returned $11.6 million to its stockholders in the form of dividends and
repurchased 0.2 million shares.
    
 
   
     ENVIRONMENTAL MATTERS -- The Company generates both hazardous and
non-hazardous wastes, the treatment, storage, transportation and disposal of
which are regulated by various governmental agencies. The Company has been
designated a potentially responsible party by the U.S. Environmental Protection
Agency in connection with one plant and various other sites. The Company has
accrued $51 million to cover future environmental remediation expenditures and
does not believe any of the matters either individually or in the aggregate will
have a material adverse effect on its capital expenditures, earnings, cash flow
or liquidity. Included in the $51 million accrual are the estimated future costs
to remediate Synergistics' facilities to Geon's historical environmental
operating practices. Capital expenditures related to the limiting and monitoring
of hazardous and non-hazardous wastes amounted to $4 million, $3 million and $7
million for 1997, 1996 and 1995, respectively. The Company estimates capital
expenditures during 1998 of approximately $3 million to $5 million. Expenditures
related to the remediation of previously contaminated sites are projected to be
$25 million to $30 million over the next five years. The risk of additional
costs and liabilities is inherent in certain plant operations and certain
products produced at the Company's plants, as is the case with other companies
involved in the PVC industry. For additional discussion of environmental
matters, refer to Note K of the Notes to Consolidated Financial Statements.
    
 
   
     YEAR 2000 -- The Company has nearly completed the conversion of its primary
commercial and financial information systems to an enterprise-wide system which
is year 2000 compliant. The Company is continuing to evaluate other systems and
processes and may incur internal staff costs as well as consulting and other
expenses to upgrade or replace these systems. Future expenditures, beyond those
which the Company would incur in the normal course of maintaining and upgrading
its systems, are not projected to be material. Certain factors that may affect
these forward-looking comments are discussed on page 37.

                      MANAGEMENT'S ANALYSIS -- CASH FLOWS
 
     Net cash used by operating and investing activities was $17.3 million in
1997, and includes the acquisition of Synergistics at a net investment of $82.2
million. Excluding the Synergistics acquisition, net cash provided by net
operating and investing activities was $64.9 million, or an increase of $73.5
million over 1996. This increase was primarily due to higher earnings before
non-cash charges (employee separation and plant phase-out, depreciation and
amortization, and deferred income taxes) of $22.0 million and the repayment of
prior-year advances to equity affiliates. In addition, lower 1997 purchases of
property were offset by changes in operating working capital (accounts
receivable plus inventory less accounts payable).
 
     In 1996, net cash used by operating and investing activities was $8.6
million, or $42.9 million lower than in 1995. The change was primarily due to
lower earnings before non-cash charges, partially offset by a decrease in
operating working capital. At December 31, 1996, operating working capital was
$18.7 million lower than in the previous year. Other uses in 1995 included
higher pension contributions, which totaled $23.6 million.
 
     Financing activities in 1997 primarily reflect the funding of the purchase
price for the Synergistics acquisition and the payment of dividends. During the
three years ended December 31, 1997, the Company repurchased $85.4 million of
common stock. During 1995, the Company issued debentures and prepaid long-term
bank debt.
 
     The Company believes it has sufficient funds to support dividends, debt
service requirements and normal capital expenditures under its existing working
capital facilities and other available permitted borrowings. The Company intends
to refinance the short-term credit facility used to initially fund the
Synergistics acquisition with long-term debt prior to the expiration of the
credit facility in June 1998. Certain factors that may affect these
forward-looking comments are discussed on page 37. Under an August 1996 Board of
Directors resolution, the Company is authorized to repurchase an additional 1.7
million shares of Geon common stock.
 
   
     INFLATION -- The Company employs a number of strategies to mitigate the
impact of inflation on financial results. A considerable amount of capital
spending is directed toward cost reduction and productivity improvement
projects. Moreover, through its research and development efforts, the Company is
continually exploring ways to reduce the cost of existing products and to
develop new products with improved performance characteristics that will command
premium prices. The Company is also reviewing and re-engineering its
administrative activities on an ongoing basis in order to streamline operations
and reduce costs.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
NOTE A.  THE COMPANY
 
     The Geon Company (Company or Geon), together with its subsidiaries, is one
of the leading North American producers and marketers of polyvinyl chloride
(PVC) resins and is the largest producer and marketer of PVC compounds. The
Company also produces and markets vinyl chloride monomer (VCM), an intermediate
precursor to PVC. The Company operates primarily in the United States and Canada
in one business segment. Sales include exports from North America of $36.2
million, $85.7 million and $183.0 million in 1997, 1996 and 1995, respectively.
 
   
NOTE B.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    
 
   
  Principles of Consolidation
    
 
     The consolidated financial statements include the accounts of the Company
and its subsidiaries. Intercompany transactions are eliminated.
 
   
  Cash and Cash Equivalents
    
 
     The Company considers all highly liquid investments purchased with a
maturity of less than three months to be cash equivalents.
 
   
  Inventories
    
 
     Inventories are stated at the lower of cost or market. Most domestic
inventories are valued by the last-in, first-out (LIFO) cost method. Inventories
not valued by the LIFO method are valued principally by the average cost method.
 
   
  Property and Depreciation
    
 
     Property, plant and equipment is recorded at cost, net of depreciation and
amortization computed principally using the straight-line method over the
estimated useful life of the asset, ranging from 3 to 15 years for machinery and
equipment and up to 40 years for buildings. Property, plant and equipment is
generally depreciated on accelerated methods for income tax purposes. Repairs
and maintenance costs are expensed as incurred, except for plant turnaround
costs, which are deferred and amortized over the period benefited. At December
31, 1997, and 1996, unamortized turnaround costs were $1.9 million and $6.4
million, respectively.
 
   
  Goodwill
    
 
     The excess of the purchase price paid over the fair value of the net assets
of businesses acquired is recorded as goodwill and amortized over a 35-year
period on a straight-line basis. Goodwill and other long-lived assets are
reviewed for impairment. Measurement of impairment may be based upon appraisals,
market values of similar assets or discounted cash flows.
 
   
  Financial Instruments
    
 
     The fair values of cash equivalents and short-term bank debt approximate
their carrying amount because of the short maturity of those instruments. The
fair values of long-term debt and debentures are estimated based on the present
value of the underlying cash flows discounted at the Company's estimated
borrowing rate. At December 31, 1997 and 1996, the fair value of long-term debt,
including debentures, approximates its carrying value.
 
     The Company periodically enters into interest rate exchange and foreign
currency forward contracts to manage exposure to foreign currency and interest
rate fluctuations. The interest rate exchange agreements generally do not
qualify for hedge accounting treatment and, accordingly, are carried at market
value, with the related gains and losses recognized immediately in income. Gains
and losses on
                                      F-60
<PAGE>   174
   
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
    
 
foreign currency contracts qualifying as hedges are deferred and recognized at
the termination or settlement of the underlying hedged item. Gains and losses on
currency contracts that do not qualify for hedge accounting are recognized
immediately in income.
 
   
  Revenue Recognition
    
 
     The Company recognizes revenues at the point of passage of title, which is
generally at the time of shipment.
 
   
  Environmental Costs
    
 
     The Company expenses, on a current basis, recurring costs associated with
managing hazardous substances and pollution in ongoing operations. Costs
associated with the remediation of environmental contamination are accrued when
it becomes probable that a liability has been incurred and the Company's
proportionate share of the amount can be reasonably estimated.
 
   
  Research and Development Expense
    
 
     Research and development costs, which were $17.1 million, $17.5 million and
$18.0 million in 1997, 1996 and 1995, respectively, are charged to expense as
incurred.
 
   
  Foreign Currency Translation
    
 
     Income statement items are translated at average currency exchange rates.
Transaction gains and losses are included in determining net income. All balance
sheet accounts of foreign subsidiaries and equity investees are translated at
the current exchange rate as of the end of the period. The Company's share of
the resulting translation adjustment is recorded as part of the other component
of stockholders' equity. The cumulative unrecognized translation adjustment loss
was $27.0 million, $18.6 million and $19.1 million at December 31, 1997, 1996
and 1995, respectively.
 
   
  Earnings Per Common Share
    
 
     In 1997, the Company adopted Statement of Financial Accounting Standards
(SFAS) No. 128, "Earnings Per Share," which replaced the computation of primary
and fully diluted earnings per share with basic and diluted earnings per share.
Earnings per share for all prior periods have been restated to conform with the
new standard.
 
     Basic earnings per share are computed using the weighted average number of
shares of common stock outstanding during the period. Earnings per share on a
diluted basis also reflect the potential dilutive effect of stock options and
restricted stock awards and other incentives.
 
   
  Stock Options
    
 
     The Company accounts for stock options in accordance with Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees."
 
   
  Australian Joint Venture
    
 
     In August 1997, the Company entered into a joint venture resulting from the
merger of its Australian PVC operations with the operations of an unrelated
party. Geon contributed certain net assets, including inventory and property and
equipment, in exchange for 37% ownership in the joint venture. This joint
venture is accounted for under the equity method. Prior to the formation of the
joint venture, Geon's Australian PVC operations had assets of approximately $44
million.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
  Recently Issued Accounting Standards
    
 
     In June 1997, the Financial Accounting Standards Board (FASB) issued SFAS
No. 130, "Reporting Comprehensive Income," which requires that an enterprise
classify items of other comprehensive income (such as foreign currency
translation adjustments) in a financial statement and display the accumulated
balance of other comprehensive income separately from retained earnings and
additional paid-in capital in the equity section of the balance sheet. The
Company will comply with the provisions of this statement upon its required
adoption in 1998.
 
     In June 1997, the FASB also issued SFAS No. 131, "Disclosures About
Segments of an Enterprise and Related Information," which establishes new
standards for the way public business enterprises report information about
operating segments in annual financial statements, and which requires that those
enterprises report selected information about operating segments in interim
financial reports issued to shareholders. It also establishes standards for
related disclosures about products and services, geographic areas and major
customers. The Company is currently studying the effects of adoption of this
statement, which will be effective for the Company beginning on December 31,
1998.
 
   
  Use of Estimates
    
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
   
  Reclassification
    
 
     Certain amounts for 1996 and 1995 have been reclassified to conform to the
1997 presentation.
 
   
NOTE C.  BUSINESS ACQUISITION
    
 
     Effective October 31, 1997, the Company acquired substantially all of the
outstanding capital stock of Synergistics Industries Limited (Synergistics) of
Mississauga, Ontario, Canada, a manufacturer of plastic compounds and materials.
The acquisition is being accounted for under the purchase method of accounting
and, accordingly, the purchase cost of approximately $86.5 million, including
related acquisition costs, has initially been allocated to assets acquired and
liabilities assumed based upon their estimated fair values. The excess of the
purchase price over the estimated fair value of net assets acquired of $63.6
million has been recorded as goodwill. The acquisition was initially financed
with a short-term credit facility (See Financing Arrangements). The operating
results of Synergistics have been included in the consolidated statement of
income from the date of acquisition.
 
     The following unaudited pro forma information presents a summary of the
consolidated results of operations of the Company and Synergistics as if the
acquisition had occurred at the beginning of 1996, with pro forma adjustments to
reflect the amortization of goodwill, interest expense on acquisition debt and
other adjustments, together with the related income tax effects. The pro forma
financial information is not necessarily indicative of the results of operations
if the acquisition had actually occurred at the beginning of the periods
presented.

     At December 31, 1997, approximately $193 million of the credit and
overdraft facilities was available. The weighted-average Canadian interest rate
on short-term borrowings was 4.1% at December 31, 1997. The Company's bank
agreements contain restrictive covenants and require the maintenance of
financial ratios. No specific restrictions have been placed on dividends or
share repurchases.
 
   
NOTE E.  LEASING ARRANGEMENTS
    
 
     The Company leases warehouse space, a production facility, machinery and
equipment, automobiles and railcars under operating leases with remaining terms
up to 12 years. Rent expense amounted to $32.1 million, $23.8 million and $16.4
million during 1997, 1996 and 1995, respectively. The future minimum lease
payments under non-cancelable operating leases with initial lease terms in
excess of one year at December 31, 1997, are as follows: 1998--$29.2 million;
1999--$26.3 million; 2000--$21.4 million; 2001--$150.4 million; 2002--$6.1
million; thereafter--$65.1 million.
 
     The Company leases a VCM production facility and related equipment under an
operating lease that expires in 2001. Under the terms of the lease, the Company
has options to renew the lease for five one-year periods and may purchase the
VCM facility and equipment at the then-fair value at any time during the lease
term. The lease provides for a substantial residual value guarantee by the
Company at the termination of the lease. During 1996, the Company amended the
lease agreement to include additional equipment for which the Company has also
assumed a $45 million construction performance obligation. Accumulated
construction in process was $38.4 million at December 31, 1997.

NOTE F.  SALE OF ACCOUNTS RECEIVABLE
    
 
     The Company has an agreement with a bank to sell an undivided interest in
certain trade accounts receivable under which, on an ongoing basis, a maximum of
$85.0 million can be sold from a designated pool subject to limited recourse.
Payments are collected from the sold accounts receivable; the collections are
reinvested in new accounts receivable for the buyers; and a yield based on
defined short-term market rates is transferred to the buyers. Buyers have
collection rights to recover payments from the receivables in the designated
pool. Sales of accounts receivable averaged $79.9 million, $40.5 million and
$68.7 million in 1997, 1996 and 1995, respectively. Accounts receivable at
December 31, 1997, and 1996, are net of $60.0 million and $68.1 million,
respectively, representing the interests in receivables sold under these
agreements. The discount from the Company's sale of receivables is included in
"Other expense, net" in the Consolidated Statements of Income.

NOTE J.  EMPLOYEE BENEFIT PLANS
 
  Pension Benefit Plans
 
     The Company has two defined benefit pension plans covering substantially
all domestic employees. The plan covering salaried employees generally provides
benefit payments using a formula that is based on employee compensation and
length of service. The plan covering union wage employees generally provides
benefit payments of stated amounts for each year of service. Annual
contributions to the plans are sufficient to satisfy legal requirements. Plan
assets consist principally of corporate and government obligations and funds
invested in equities. Annual pension expense included the following components:

     At December 31, 1997, the plan assets were $241.8 million, which represents
an increase of $29.6 million over year-end 1996. The growth in these assets was
the result of actions taken by the Company and favorable security markets.
Income earned on these assets was $19.6 million, which represents a return of
18% in 1997. The Company also made contributions in 1997 of $11.0 million.

     A curtailment loss of $10.7 million was recorded in 1997 relating to a
voluntary retirement program. The curtailment loss is included in the employee
separation charge of $15.0 million recognized in the consolidated statement of
income. At December 31, 1997, and 1996, $2.3 million and $3.3 million,
respectively, were recorded as the cumulative additional minimum pension
liability and included in the other component of stockholders' equity as a
reduction.
 
  Retirement Savings Plan
 
     The Company maintains a voluntary retirement savings plan (RSP) for most
employees. Under provisions of the RSP, eligible employees can receive Company
matching contributions up to the first 6% of their eligible earnings. For 1997,
1996 and 1995, Company contributions amounted to $4.7 million each year. In
addition, the Company makes profit-sharing payments to the RSP for those
employees not covered by management incentive compensation plans. In 1997, 1996
and 1995, these profit-sharing payments totaled $.8 million, $1.0 million and
$2.5 million, respectively.
 
  Post-Retirement Benefit Plans
 
     The Company sponsors several unfunded defined benefit post-retirement plans
that provide certain health care and life insurance benefits to eligible
employees. The health care plans are contributory, with retiree contributions
adjusted periodically, and contain other cost-sharing features such as deduct-

     At December 31, 1997, the average assumed rate of increase in the per
capita cost of covered benefits was 8% for 1998 and is assumed to decrease
gradually to 5% in 2005 and thereafter. An increase in the assumed health care
cost trend rates by 1% in each year would increase the APBO as of December 31,
1997, by $4.3 million, and the aggregate of the service and interest cost
components of net periodic post-retirement benefit cost for 1997 by $0.3
million.
 
     The discount rates used in determining the APBO at December 31, 1997, and
1996, were 7.2% and 7.5%, respectively. The decrease in the discount rate in
1997 from 1996 increased the APBO at December 31, 1997, by $2.8 million.
 
NOTE K.  COMMITMENTS
 
  Environmental
 
     The Company has been notified by the U.S. Environmental Protection Agency,
a state environmental agency or a private party that it may be a potentially
responsible party (PRP) in connection with seven active and inactive
non-Company-owned sites. While government agencies frequently claim PRPs are
jointly and severally liable at these sites, in the Company's experience,
interim and final allocation of liability costs are generally made based on the
relative contribution of waste. The Company believes that it has potential
continuing liability with respect to only four such sites. In addition, the
Company initiates corrective and preventive environmental projects of its own to
ensure safe and lawful activities at its operations. The Company believes that
compliance with current governmental regulations at all levels will not have a
material adverse effect on its financial condition.
 
     Based on estimates prepared by the Company's environmental engineers and
consultants, the Company at December 31, 1997, had accruals totaling $51.0
million to cover future environmental expenditures related to previously
contaminated sites. Of this accrued amount, $18.2 million is attributable to
future remediation expenditures at the Calvert City, Kentucky, site and less
than $0.1 million is attributable to off-site environmental remediation
liabilities, including the four sites mentioned above. An additional $25.0
million is attributable to the properties acquired as part of the Synergistics
acquisition, and is related to anticipated costs to remediate these facilities
to Geon's historical environmental operating practices.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
    
 
     The remaining amount is primarily attributable to other environmental
remediation projects at nine other Company-owned facilities. At Calvert City,
consent orders have been signed with both the U.S. Environmental Protection
Agency and the Commonwealth of Kentucky Department of Environmental Protection,
which provide for a sitewide remediation program primarily to remove ethylene
dichloride from groundwater, the cost of which has been accrued. The Company
expended $5.0 million, $6.1 million and $3.0 million during 1997, 1996 and 1995,
respectively, on the remediation of such sites.
 
   
  Guarantees
    
 
     At December 31, 1997, the Company, through an indemnification agreement
with BFG, is contingently liable through December 31, 2001, with respect to
guarantees of securities of other issuers in the amount of $47.5 million, for
which the Company would be reimbursed by Occidental Chemical Holding Corporation
for any amounts paid under the guarantees.
 
     The Company has a 50% participation in a joint venture operating a
chlor-alkali plant. The Company has guaranteed $97.5 million of the joint
venture's outstanding senior secured notes, maturing in 2017.
 
  Other
 
     The Company and its subsidiaries have commitments for a substantial portion
of its key raw material feedstocks and energy incidental to the ordinary course
of business. The Company is also from time to time subject to routine litigation
incidental to its business. The Company believes that any liability that may
finally be determined would not have a material adverse effect on its financial
condition.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
    
 
     SFAS No. 109, "Accounting for Income Taxes," requires that deferred tax
assets be reduced by a valuation allowance if it is more likely than not that
some portion or all of the deferred tax assets will not be realized. As
realization of the foreign tax credit carryforwards is considered uncertain, a
valuation allowance has been recorded. The Company believes that the timing of
the reversal of its deferred tax liabilities, principally relating to
accelerated depreciation, will be sufficient to fully recognize its remaining
deferred tax assets. In particular, the turnaround of the largest deferred tax
asset, related to accounting for post-retirement benefits other than pensions,
will occur over an extended period of time and, as a result, will be realizable
for tax purposes over those future periods.
 
     During 1996 the Company finalized the effects of the step-up in the tax
basis of its assets as a result of formation and recorded adjustments to
deferred taxes and equity of $25.9 million.
 
     The Company has provided for U.S. federal and foreign withholding tax on
$24.1 million, or 19% of foreign subsidiaries' undistributed earnings, as of
December 31, 1997. Regarding the undistributed earnings on which no federal and
foreign withholding has been provided, earnings are intended to be reinvested
indefinitely. It is not practical to determine the amount of income tax
liability that would result had such earnings been actually repatriated. On
repatriation, certain foreign countries impose withholding taxes. The amount of
foreign withholding taxes that would be payable on remittance of the entire
amount of undistributed earnings would approximate $7.3 million.
 
     During 1997, 1996 and 1995, the Company paid income taxes net of refunds of
$1.9 million, $2.2 million and $37.9 million, respectively. The Company has a
net operating loss carryforward of approximately $38.7 million, of which $12.4
million will expire in 2011 and the remaining $26.3 million will expire in 2012.
In addition, the Company has foreign tax carryforwards of $6.0 million, which
will expire from 1999 through 2002, and an alternative minimum tax credit
carryforward of $3.9 million.
 
NOTE N.  EMPLOYEE SEPARATION AND PLANT PHASE-OUT CHARGES
 
     In 1997, the Company recorded a $15.0 million before-tax charge, primarily
for employee separation costs related to position reductions at its
headquarters. Of this, $10.7 million related to enhanced retirement pension
benefits and the balance to employee separation and associated costs. In
addition, in 1995, the Company recorded a $63.9 million before-tax charge,
primarily related to the reconfiguration of the manufacturing of vinyl compound
products.
 
NOTE O.  STOCK OPTION AND STOCK INCENTIVE PLANS
 
     The 1995 Incentive Stock Plan provides for the awarding or granting of
options to purchase common stock of the Company. Generally, options granted
become exercisable at the rate of 35% after one year, 70% after two years and
100% after three years. Certain options are fully exercisable after grant. The
term of each option cannot extend beyond 10 years from the date of grant.
Certain options carry with them limited stock appreciation rights exercisable in
the event of a change in control. All options under the plans have been granted
at 100% of market (as defined) on the date of the grant. In addition, certain
senior-level executives received special awards in connection with the formation
of the Company and the initial public offering (IPO) of stock on April 29, 1993,
which included stock options with rights to purchase 1.2 million shares. These
awards became exercisable four years after grant date. The Company also has a
stock plan for non-employee directors under which options are granted.

     Under the Company's incentive programs, senior executives and other key
employees are also eligible annually to receive bonus awards, consisting of
stock or a combination of stock and cash. Under these plans, performance
measures are established and used to determine the payout, if any.
 
     At December 31, 1997, restricted shares totaling 0.4 million were
outstanding. The restrictions generally lapse over one to three years, with some
subject to acceleration based on the Company's stock price performance. The
unamortized portion of compensation expense related to these stock awards
included in other component of stockholders' equity was $0.8 million and $1.3
million at December 31, 1997, and 1996, respectively.
 
     The Company applies APB Opinion 25, "Accounting for Stock Issued to
Employees," and related interpretations in accounting for its incentive plans.
Accordingly, no compensation cost has been recognized for its fixed option plans
because the exercise price of the Company's stock options equals the market
price of the underlying stock on the date of grant. Had the compensation cost
for the stock options granted in 1997 and 1996 been determined based upon the
fair value at the grant date, consistent with the fair value method of FASB
Statement No. 123, "Accounting for Stock-Based Compensation," the Company's net
earnings and earnings per share would have been reduced by $2.1 million ($.09
per share) in 1997 and $0.7 million ($.03 per share) in 1996 on a diluted basis.
The impact in 1995 was not material. The fair value of the stock options at the
grant date was estimated using the Black-Scholes option pricing model with an
assumed risk-free interest rate of 5.4% and 5.7%, an assumed dividend yield of
2.5% and 2.0%, and stock price volatility of 28.5% and 29.8% for 1997 and 1996,
respectively. A seven-year weighted average life was used for both 1997 and
1996.
 
     The compensation cost related to the stock portion of the annual incentive
plans, three-year incentive plan and amortization of restricted stock awarded at
the IPO amounted to $2.3 million, $3.0 million and $4.2 million in 1997, 1996
and 1995, respectively.
 
     At December 31, 1997, 3.1 million shares were reserved for future issuance
upon exercise of stock options granted or were available for future grants under
the Company's incentive plans.

(1) On February 11, 1993, the Company was formed as a wholly owned subsidiary of
    The BFGoodrich Company (BFG) in preparation for the IPO of its common stock
    on April 29, 1993. BFG transferred to the Company substantially all of the
    operating assets and liabilities of its Geon Vinyl Division, other than the
    net assets of the chlor-alkali, ethylene and utility operations of BFG
    located principally at Calvert City, Kentucky (Calvert Facilities), in
    exchange for the Company's common stock.
 
    The historical results for 1993 and 1992 include the results of operations
    associated with the Calvert Facilities through February 28, 1993. The cost
    of VCM consumed from the Calvert Facilities was recorded at historical
    intercompany cost through April 29, 1993.
 
    The pro forma results for 1993 and 1992 exclude the results of operations
    associated with the Calvert Facilities. The data are also presented as if
    the Company purchased the VCM associated with the Calvert Facilities at
    market prices rather than at historical intercompany costs. Subsequent to
    the initial public offering of the Company's common stock on April 29, 1993,
    purchases of VCM

    from BFG were at market prices. The pro forma results also include the cost
    associated with certain May 1993 bank arrangements, as if they had occurred
    at the beginning of 1993.
 
(2) The employee separation and plant phase-out charges reduced basic earnings
    per share as follows: 1997--$.40; 1995--$.56; 1993--$.22; 1992--$.36.
 
   
(3) The employee separation and plant phase-out charges reduced diluted earnings
    per share as follows: 1997--$.39; 1995--$.52; 1993--$.22; 1992--$.36.

NOTE A
    
 
   
     The accompanying unaudited condensed consolidated financial statements of
The Geon Company (Company or Geon) have been prepared in accordance with
generally accepted accounting principles for interim financial information and
the instructions to Form 10-Q, and Article 10 of Regulation S-X. Accordingly,
they do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements. In the opinion
of management, all adjustments (consisting of normal recurring accruals)
considered necessary for a fair financial presentation have been included.
Operating results for the three and nine month periods ended September 30, 1998
are not necessarily indicative of the results that may be expected for the year
ending December 31, 1998. For further information, refer to the consolidated
financial statements and notes thereto included in the Company's annual report
on Form 10-K for the year ended December 31, 1997. Certain amounts for 1997 have
been reclassified to conform to the 1998 interim period presentation.
    
 
   
NOTE B
    
 
   
     There are pending or threatened against the Company or its subsidiaries
various claims, lawsuits and administrative proceedings, all arising from the
ordinary course of business with respect to employment, commercial, product
liability and environmental matters, which seek remedies or damages. The Company
believes that any liability that may finally be determined should not have a
material adverse effect on the Company's consolidated financial position.

     The decrease in the LIFO reserve is primarily the result of significant
reductions in the price of ethylene and chlorine, key raw materials used in the
production of PVC resins and compounds.

     In June 1997, the FASB issued Statement No. 130, "Reporting Comprehensive
Income" (SFAS 130). The pronouncement requires that an enterprise classify items
of other comprehensive income or "non-owner equity changes" as referred to by
the Company, by their nature in a financial statement and display the
accumulated non-owner equity changes separately from retained earnings and
additional paid-in capital in the equity section of the balance sheet. The
Company adopted SFAS 130 on January 1, 1998. Certain reclassifications have been
made to the 1997 financial statements to conform to the requirements of this
pronouncement.

     In June 1998, the Company announced that it had signed a non-binding letter
of intent to enter into transactions with Occidental Chemical Corporation
(Oxychem), a subsidiary of Occidental Petroleum Corporation. If completed, the
transactions would result in (i) the creation of a joint venture, comprised of
the polyvinyl chloride suspension/mass resin businesses and related supporting
operations of both companies, which would be 76 percent owned by Oxychem and 24
percent by Geon; (ii) the creation of a joint venture, comprised of the powder
compound business of both companies, which would be 90 percent owned by Geon and
10 percent owned by Oxychem; and (iii) the acquisition by Geon of Oxychem's
vinyl compound, film and pellet businesses located at Burlington, New Jersey,
and Pasadena, Texas. The proposed transactions with Oxychem are subject to a
number of conditions, including the execution of definitive agreements, approval
of the board of directors of each company and the Geon shareholders, and other
required approvals.
    
 
   
     In June 1998, the Company completed the acquisition of Plast-O-Meric, Inc.,
(Plast-O-Meric) a privately held custom formulator of vinyl plastisols and
polyurethane systems. Also in June 1998, the Company acquired the Wilflex Ink
Division (Wilflex) of Flexible Products Company. Wilflex is a manufacturer and
marketer of vinyl plastisol ink products. In September 1998, The Company
acquired Adchem, Inc., (Adchem) a custom formulator of vinyl plastisols and a
marketer of polymer additives such as blowing agents and pigments. The combined
revenues of the acquired companies were approximately $110 million for their
most recently completed fiscal years, and the companies employ approximately 320
people. The combined purchase price for the acquired businesses was
approximately $64 million.
    
 
   
     In June 1998, Geon and Orica Limited (formerly ICI Australia Limited)
announced approval of their intention to float their entire interests in the
joint venture company, Australian Vinyls Corporation Limited pending favorable
market conditions. Geon and Orica Limited have indefinitely postponed the public
offering due to the unfavorable Australian equity market conditions. Geon holds
a 37.4 percent share of the joint venture.

     In March 1998, the Company announced an agreement with Bayer Corporation
under which Bayer will utilize a pipeline to transport anhydrous chlorine (HCl)
from its plant in Baytown, Texas to Geon's VCM plant in LaPorte, Texas. Geon has
constructed an oxychlorination facility at LaPorte which will convert the
anhydrous chlorine for use in making VCM at its LaPorte Facility. Operation of
the pipeline and related facilities commenced early in the fourth quarter of
1998.
    
 
   
     In September, the Company announced a $19 million modernization and
expansion of its Henry, Illinois specialty polyvinyl chloride (PVC) resin plant.
The capital investment will upgrade manufacturing lines and expand capacity by
approximately 25%, enabling the Company to continue to meet growing demand for
its products.
    
 
   
ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
    
 
   
INDUSTRY CONDITIONS:
    
 
   
     Based on industry data, North American (U.S. and Canada) producer shipments
of polyvinyl chloride (PVC), including exports, are estimated to have decreased
less than 2% in the third quarter of 1998 as compared to the second quarter of
1998 and were about 4% higher than the same period in 1997. For the first nine
months of 1998, North American producer shipments are estimated to have
increased 4% as compared to the same period in 1997. Exports for the third
quarter decreased 32%

over the same period a year ago, and were 22% below the second quarter of 1998.
Export shipments declined in the third quarter primarily as a result of the
protracted economic dislocation in East Asia. Even though North American PVC
demand has remained relatively strong, however PVC prices and margins remained
under pressure.
    
 
   
     Capacity utilization (shipments/capacity) for North America was estimated
at 91% of effective capacity (85% of nameplate) during the third quarter of
1998, a decline of 2% from the second quarter due to a modest slowdown in
shipments. Capacity utilization was 3% below the same period last year due to
750 million pounds of capacity expansion early in 1998 by two PVC resin
suppliers.
    
 
   
     Industry operating margins (the spread between PVC resin selling prices and
large buyer ethylene and chlorine costs as reported in industry trade journals
and newsletters) for the largest PVC resin market applications were unchanged on
average for third quarter of 1998 as compared to the previous quarter and have
decreased 1.5 cents per pound as compared to the same quarter of 1997. Price
increases announced in the first half of the year did not occur primarily
because weakness in export prices caused primarily by the economic dislocations
in East Asia as well as of declining raw material costs and underutilized
capacity due largely to additions brought on in first quarter of 1998. Again in
the third quarter of 1998 lower average selling prices were offset by lower
ethylene and chlorine costs.
    
 
   
     The fourth quarter of 1998 began with PVC resin operating margins at
historic lows despite relatively strong demand. Volumes in the fourth quarter
typically experience a seasonal decline from the third quarter. A fourth quarter
price increase has been announced by major suppliers in the industry; however,
it has historically been difficult to obtain increases in the fourth quarter due
to the seasonal demand slowdown. Certain factors that may affect these
forward-looking comments are discussed under "Cautionary Note on Forward-Looking
Statements".
    
 
   
RESULTS OF OPERATIONS
    
 
   
     Sales for the third quarter were $328.0 million, an increase of $24.3
million or 8% from the same period last year. The sales increase is largely due
to the incremental sales of acquired businesses, which were partially offset by
lower PVC sales resulting from the decline in resin selling prices of
approximately 9.0 cents per pound as compared to average third quarter pricing.
The remainder of the decline is attributable to the formation of the Australian
Vinyls Corporation joint venture from a previously consolidated subsidiary in
the third quarter of 1997. Year-to-date sales were $983.2 million, a 5% increase
over 1997. Excluding the employee separation charge of $15 million and favorable
income tax adjustment in 1997 of $2.0 million, year-to-date net income in 1998
declined $9.4 million as compared to 1997. Operating income for the first nine
months, excluding the impact of the $15.0 million employee separation charge in
1997, declined by $17.1 million to $38.5 million. For the third quarter of 1998,
operating income declined by $1.8 million from the same period a year ago. The
decline in earnings is due primarily to the decline in resin operating margins
as discussed under "Industry Conditions" above. In addition, costs associated
with a scheduled maintenance shutdown in the second quarter of 1998 at the
Company's vinyl chloride monomer plant in LaPorte, Texas unfavorably affected
year-to-date pretax earnings by approximately $3.5 million. These were partially
offset by the earnings of businesses acquired in the last year, including
Synergistics Industries Limited (Synergistics), Plast-O-Meric, Wilflex and
Adchem. Net income for the quarter was $6.2 million or $2.4 million below the
same period last year, excluding the favorable tax adjustment in 1997.
    
 
   
     The Performance Polymer and Services market segments, which includes PVC
compounds, specialty dispersion resins, plastisol formulators and Polymer
Diagnostics, Inc., had aggregate sales revenues 55% higher in the third quarter
of 1998 as compared to the same quarter last year, and 4% higher than the
previous quarter, due largely to the acquisitions of Synergistics in the fourth
quarter of 1997

and Plast-O-Meric, Wilflex and Adchem in 1998. Suspension/mass resin shipment
volumes were approximately 2% lower than in the second quarter, consistent with
the decline for the industry, and 1% lower than in the same quarter in 1997.
Suspension/mass resin selling prices decreased approximately 27% in the third
quarter of 1998 from the same quarter last year.
    
 
   
     Selling, general and administrative expenses increased by $20.0 million
from 1997 to $55.4 million in the first nine months of 1998. This increase is
primarily due to the additional expenses associated with the acquired
businesses. Similarly, depreciation and amortization has increased over the same
periods last year as a result of the additional depreciation on assets acquired
and the amortization expense related to acquisition goodwill.
    
 
   
INTEREST & OTHER INCOME/EXPENSE
    
 
   
     Interest expense increased $1.8 million in the third quarter of 1998 and
$3.8 million for the first nine months of 1998 as compared to the corresponding
periods last year. This increase is a result of the higher average short-term
borrowings resulting from the Synergistics acquisition late in 1997 and the
three business acquisitions in 1998. In 1997, the Company's short-term
borrowings were primarily related to the construction of the Sunbelt facility.
Other expense, net increased to $2.5 million for third quarter 1998 as compared
to $1.6 million in the same quarter last year. The increase in net expense is
primarily the result of restructuring charges recognized by Australian Vinyls
Corporation and losses incurred in 1998 by the Sunbelt chlor-alkali joint
venture, resulting from declines in chlor-alkali selling prices. Year-to-date
other income (expense), net was income of $0.2 million for the first nine months
of 1998 as compared to an expense of $4.5 million in 1997, largely due to the
equity earnings from Sunbelt and Australian Vinyls Corporation. Foreign currency
losses for the third quarter of 1998 were $0.3 million, as compared with $0.9
million in the same quarter last year. Year-to-date foreign currency losses were
$0.6 million and $1.6 million in 1998 and 1997, respectively. Currency losses
resulted primarily from fluctuations in Australian currency.
    
 
   
TAXES
    
 
   
     Income tax expense for the first nine months of 1998 was approximately 41%
of pre-tax income, as compared with 40% for the first nine months of 1997,
excluding the impact of a one-time favorable tax adjustment in 1997. The
increase in the effective tax rate is due in part to non-deductible goodwill
associated with the Synergistics acquisition as well as the effect of a state
income tax refund in 1997. The third quarter effective tax rates approximates
the year-to-date rates.
    
 
   
CAPITAL RESOURCES AND LIQUIDITY
    
 
   
     During the nine months ended September 30, 1998, the Company generated
$96.5 million of cash from operating activities as compared to $82.4 million
during the same period of 1997. The year-to-date 1998 earnings before non-cash
charges were $15.6 million below last year. Operating working capital (accounts
receivable plus inventory less accounts payable) decreased by $24.7 million in
the first nine months of 1998, compared with an increase of $5.0 million in
1997, largely as a result of lower material costs, lower PVC resin selling
prices, and an increase in receivables sold in 1998.
    
 
   
     Investing activities include the $56.1 million of net cash paid for the
acquisitions of Plast-O-Meric, Wilflex and Adchem in 1998. Purchases of property
were $27 million and $28.5 million for the first three quarters of 1998 and
1997, respectively. Capital expenditures for the full year of 1998 are projected
to be approximately $50 million, consistent with 1997 levels. Investing
activities for the first half of 1998 also included $2.0 million of investments
in and advances to equity affiliates as compared with

$66.6 million in 1997. These 1997 advances primarily relate to the Sunbelt
chlor-alkali joint venture with Olin and were repaid to the Company in the 4th
quarter of 1997.
    
 
   
     Financing activities through September 1998 reflect a decrease in
short-term debt of $35.9 million. During the same period in 1997, short-term
borrowings increased by $34.2 million, primarily to fund the advances for
construction of the Sunbelt chlor-alkali plant. In addition, in the first half
of 1997, the Company repurchased 200,000 shares of common stock for $4.1
million. As of September 30, 1998, 1.7 million remaining shares are authorized
for repurchase under an August 1996 Board of Directors resolution.
    
 
   
     The Company believes it has sufficient funds to support dividends, debt
service requirements, normal capital and operating expenditures, and
expenditures related to expansion of its Henry, Illinois plant, based on
projected operations, existing working capital facilities and other available
permitted borrowings.
    
 
   
YEAR 2000
    
 
   
     Certain factors that may affect the following forward-looking comments
related to Year 2000 readiness are discussed under "Cautionary Note on
Forward-Looking Statements".
    
 
   
  State of Readiness
    
 
   
     Beginning in 1997, the Company has been actively involved in surveying,
assessing and correcting Year 2000 problems within its information technology
structure. The Company implemented a new integrated commercial business
information system in 1997 which is Year 2000 compliant and will support
approximately 90% of the current operations. The information technology
structure includes, among others, commercial business information systems,
manufacturing information systems, desktop computing and data and communication
networks. The information system correction process is substantially complete.
The Company maintains its critical information technology systems in close
cooperation with its suppliers. The Company is not currently operating any
legacy systems which are no longer being supported by the original supplier.
    
 
   
     The most critical non-information technology systems, such as automated
process control equipment, are relatively new and are being upgraded and
maintained with the help of the Company's various suppliers. To date, the
Company's investigation of these systems has not revealed any Year 2000
problems, however, investigation in this area continues.
    
 
   
     Each operating unit's purchasing and production control departments are in
the process of analyzing the unit's key third-party dependencies and working
with each of these key suppliers to determine the supplier's Year 2000 status.
Since the Company's key suppliers are in the process of conducting similar
investigations with their own key suppliers, and so on, the Company has had
limited success in obtaining reliable Year 2000 compliance certifications.
    
 
   
  Costs
    
 
   
     The Company has expended only a limited amount on Year 2000 issues,
consisting principally of personnel costs incurred in the scope of normal
operations. The implementation of the new integrated commercial business
information system (a substantial investment) and other software replacements
and upgrades in the ordinary course of business have enhanced the Company's Year
2000 readiness without incremental costs. The Company does not anticipate that
future Year 2000 costs related to information technology that are beyond the
scope of normal operations will be significant.

                                   UNAUDITED
    
 
   
     The Company is in the process of developing contingency plans to prevent
and/or mitigate the impact of Year 2000 failures. These plans will likely result
in some expenditures, primarily increased inventory costs to assure adequate
supplies, the exact amount of which is not known at this time.
    
 
   
  Risks
    
 
   
     In the early weeks of fiscal 2000, the Company may experience some random
or unforeseen supply chain disruptions that may affect its ability to produce
and distribute key products. The disruptions will be material if the U.S.
experiences significant interruptions in basic services, such as the electric
power grid, telephone service or the banking system.
    
 
   
ENVIRONMENTAL MATTERS
    
 
   
     The Company is subject to various federal, state and local environmental
laws and regulations concerning emissions to the air, discharges to waterways,
the release of materials into the environment, the generation, handling,
storage, transportation, treatment and disposal of waste materials or otherwise
relating to the protection of the environment.
    
 
   
     The Company maintains a disciplined environmental and industrial safety and
health compliance program and conducts internal and external regulatory audits
at its plants in order to identify and categorize potential environmental
exposures and to assure compliance with applicable environmental, health and
safety laws and regulations. This effort has required and may continue to
require process or operational modifications, the installation of pollution
control devices and cleanups. The Company estimates capital expenditures related
to the limiting and monitoring of hazardous and non-hazardous wastes during 1998
to approximate $2 million to $4 million. Certain factors that may affect these
forward-looking comments are discussed under "Cautionary Note on Forward-Looking
Statements".
    
 
   
     The Company believes that compliance with current governmental regulations
will not have a material adverse effect on its capital expenditures, earnings,
cash flow or liquidity. At September 30, 1998, the Company had accruals totaling
approximately $50 million to cover potential future environmental remediation
expenditures. Environmental remediation expenditures in 1998 are estimated to
approximate the level of 1997.

           On September 14, 1998, the Company filed an 8-K announcing a
           $19 million modernization and expansion of its Henry,

           percent, enabling Geon to continue to meet growing demand
           for its products.

The Board of Directors
The Geon Company
One Geon Center
Avon Lake, Ohio 44012
 
Attention: William F. Patient
        Chairman and Chief Executive Officer
 
Ladies and Gentlemen:
 
     You have requested our opinion as to the fairness, from a financial point
of view, to The Geon Company (together with its subsidiaries and affiliates, the
"Company") of the interest and other consideration proposed to be received by
the Company in the PVC Partnership and the Compounding Partnership (together,
the "Joint Venture Transactions") being formed by the Company and Occidental
Chemical Corporation (together with its subsidiaries and affiliates, "OxyChem")
in exchange for the components of the business or assets to be contributed by
the Company to the Joint Venture Transactions pursuant to the Master Transaction
Agreement (as defined below). Pursuant to and as set forth in more detail in the
Master Transaction Agreement, dated as of December 22, 1998 (the "Agreement") by
and between the Company and OxyChem, the Company and OxyChem will contribute
components of the business or assets of the Company's and OxyChem's respective
suspension/mass polyvinyl chloride, vinyl chloride monomer businesses, HCC chlor
alkali business and powder/dry blend compounding businesses (together, the
"Businesses") to the Joint Venture Transactions, and the Company and OxyChem
will each receive ownership stakes and/or other consideration in the Joint
Venture Transactions for their respective contributions to the Joint Venture
Transactions.
 
   
     In arriving at our opinion, we have reviewed (i) the Agreement and related
agreements; (ii) certain information concerning the Businesses and certain
publicly available information concerning certain other companies engaged in
businesses comparable to those of the Joint Venture Transactions; (iii) publicly
available terms of certain transactions involving companies or assets comparable
to the Businesses and consideration received in such transactions; (iv) the
audited financial statements of the Company and Occidental Petroleum Corporation
(together with its subsidiaries and affiliates, "OPC") for the fiscal year ended
December 31, 1997, and the unaudited financial statements of the Company and OPC
for the period ended September 30, 1998; (v) certain agreements with respect to
outstanding indebtedness or obligations to be contributed to the Joint Venture
Transactions; (vi) certain internal financial analyses and forecasts prepared by
the Company and its management; and (vii) the terms of other business
combinations that we deemed relevant.
    
 
     In addition, we have held discussions with certain members of the
management of the Company and OxyChem with respect to certain aspects of the
Joint Venture Transactions, the past and current business operations of the
Company and OxyChem, the financial condition and future prospects and operations
of the Company and OxyChem, the effects of the Joint Venture Transactions on the
financial condition and future prospects of the Company, and certain other
matters we believed necessary or appropriate to our inquiry. We have visited
certain representative facilities of the Company and Oxy-
                                        1
<PAGE>   203
 
Chem, and reviewed such other financial studies and analyses and considered such
other information as we deemed appropriate for the purposes of this opinion.
 
     In giving our opinion, we have relied upon and assumed, without independent
verification, the accuracy and completeness of all information that was publicly
available or was furnished to us by the Company and OxyChem or otherwise
reviewed by us, and we have not assumed any responsibility or liability
therefor. We have not conducted any valuation or appraisal of any assets or
liabilities, nor have any such valuations or appraisals been provided to us. In
relying on financial analyses and forecasts provided to us, we have assumed that
they have been reasonably prepared based on assumptions reflecting the best
currently available estimates and judgments by management as to the expected
future results of operations and financial condition of the Company to which
such analyses or forecasts relate. We have also assumed that the Joint Venture
Transactions will have the tax consequences described in discussions with, and
materials furnished to us by, representatives of the Company, and that the other
transactions contemplated by the Agreement will be consummated as described in
the Agreement. We have relied as to all legal matters relevant to rendering our
opinion upon the advice of counsel.
 
     Our opinion is necessarily based on economic, market and other conditions
as in effect on, and the information made available to us as of, the date
hereof. It should be understood that subsequent developments may affect this
opinion and that we do not have any obligation to update, revise, or reaffirm
this opinion.
 
     In addition, we were not requested to and did not provide advice concerning
the structure, the specific amount of the consideration, or any other aspects of
the Joint Venture Transactions, or to provide services other than the delivery
of this opinion. We were not authorized to and did not solicit any expressions
of interest from any other parties with respect to the sale of all or any part
of the Company or any other alternative transaction. We did not participate in
negotiations with respect to the terms of the Joint Venture Transactions.
Consequently, we have assumed that such terms are the most beneficial terms from
the Company's perspective that could under the circumstances be negotiated among
the parties to such transactions, and no opinion is expressed whether any
alternative transaction might produce consideration for the Company in an amount
in excess of that contemplated in the Joint Venture Transactions.
 
     We will receive a fee from the Company for the delivery of this opinion.
J.P. Morgan and its affiliates maintain investment banking and other business
relationships with Geon and OPC and their respective affiliates, for which it
receives customary fees. In the ordinary course of their businesses, our
affiliates may actively trade the debt and equity securities of the Company or
OPC for their own account or for the accounts of customers and, accordingly,
they may at any time hold long or short positions in such securities.
 
     On the basis of and subject to the foregoing, it is our opinion as of the
date hereof that the interest and other consideration received in exchange for
the components of the business or assets to be contributed by the Company to the
Joint Venture Transactions is fair, from a financial point of view, to the
Company.
 
     This letter is provided to the Board of Directors of the Company in
connection with and for the purposes of its evaluation of the Joint Venture
Transactions. This opinion does not constitute a recommendation to any
stockholder of the Company as to how such stockholder should vote with respect
to the Joint Venture Transactions.
 
Very truly yours,
 
J.P. MORGAN SECURITIES INC.

<PAGE>   216
 
     PVC Contribution Agreement, the Geon Compounding Contribution Agreement or

     as of the Closing Date; and
 
          (g) not agree, whether in writing or otherwise, to take any action it

of their products.
 
     3.4 FURTHER ACTIONS.
 
          (a) Each Party will use its commercially reasonable efforts to take,
     or cause to be taken, all other action and do, or cause to be done, all
     other things necessary, proper or appropriate to resolve the objections, if
     any, as may be asserted by any Authority with respect to the transactions
     contemplated hereby under any antitrust laws or regulations; provided that
     no Party shall be required to take any action that could have any Material
     Adverse Effect on it or its Affiliates or that would, or would be
     reasonably likely to, materially frustrate the financial or other business
     benefits reasonably expected to be derived by such Party from the
     transactions contemplated by this Agreement.
 
          (b) Subject to the terms and conditions hereof, each Party agrees to
     act in good faith and to use its commercially reasonable efforts to take,
     or cause to be taken, all actions and to do, or cause to be done, all
     things necessary, proper or advisable to consummate and make effective the
     transactions contemplated by this Agreement and under the Related
     Agreements to be entered into by such Party or its Affiliates at Closing,
     and to confirm that such transactions have been accomplished, including (i)
     using all commercially reasonable efforts: (A) to obtain and effect prior
     to the Closing Date all necessary Consents and Filings, including under the
     HSR Act and the Competition Act; and (B) to obtain prior to the Closing
     Date all Government Licenses or consents to the transfer of any Government
     Licenses that are transferable by it or its Affiliates necessary to
     consummate the transactions contemplated hereby and by the Related
     Agreements and to allow for the prudent and uninterrupted operation of the
     Subject Business by the PVC Partnership, the Compounding Partnership, Canco
     2 or Geon, as the case may be, after the Closing. Each Party shall furnish
     to the other Party and its Affiliates such necessary information and
     assistance as the other may reasonably request in connection with its
     preparation of any such Filings or other materials required in connection
     with the foregoing.
 
          (c) Each Party shall use its commercially reasonable efforts to
     procure all Consents that are necessary to transfer its Subject Business to
     the PVC Partnership, the Compounding Partnership, Canco 1, Canco 2 or Geon,
     as the case may be. Notwithstanding any other provision of this Agreement
     to the contrary, the Parties hereto acknowledge and agree that, at the
     Closing, no Person will assign to the PVC Partnership, the Compounding
     Partnership, Canco 1, Canco 2 or Geon, as the case may be, any contracts or
     warranties that by their terms require Consent from any other contracting
     party thereto, unless any such Consent has been obtained prior to the
     Closing Date. Before the Closing, each Party will use its commercially
     reasonable efforts and cooperate with the other Party (the "Contracting
     Party") in obtaining any necessary Consents to the assignment of the
     contracts or warranties, including by furnishing to the Contracting Party
     or other parties to any contract or warranty summary financial information
     and other information with respect to the PVC Partnership, the Compounding
     Partnership, Canco 1, Canco 2 or Geon, as the case may be, reasonably
     requested by the Contracting Party or such other parties and taking any
     such other actions (which, subject to any provisions to the contrary
     included in any Related Agreement, shall not include the incurrence of any
     expense not otherwise required to be incurred) as the Contracting Party or
     such other parties may reasonably request for the purpose of obtaining any
     releases, waivers or terminations as the Contracting Party may reasonably
     request on behalf of itself or any
 
                                       11
<PAGE>   217
 
     Affiliate. No representation is made by the Contracting Party with respect
     to whether any Consent to assign a contract or warranty will be obtainable,
     and in no event shall the initial capital contributions be subject to
     reduction as a result of any contract or warranty not being assigned to the
     PVC Partnership, the Compounding Partnership, Canco 1, Canco 2 or Geon, as
     the case may be, at the Closing by virtue of the necessary Consent not
     being obtained. Following the Closing, the Parties shall cooperate with
     each other and use commercially reasonable efforts to obtain those Consents
     that were not obtained prior to the Closing and (i) if such Consents are
     obtained following the Closing, the Contracting Party and its Affiliates
     shall execute and deliver any other and further instruments of assignment,
     assumption, transfer and conveyance and take such other and further action
     as the PVC Partnership, the Compounding Partnership, Canco 1, Canco 2 or
     Geon, as the case may be, may request in order to assign to the PVC
     Partnership, the Compounding Partnership, Canco 1, Canco 2 or Geon, as the
     case may be, any contract or warranties to which such Consents relate and
     (ii) pending such transfer or issuance to the PVC Partnership, the
     Compounding Partnership, Canco 1, Canco 2 or Geon, as the case may be, the
     Contracting Party and its Affiliates shall provide, to the extent they may
     lawfully do so, the PVC Partnership, the Compounding Partnership, Canco 1,
     Canco 2 or Geon, as the case may be, with the benefits of any such
     contracts or warranties, in which case, the PVC Partnership, the
     Compounding Partnership, Canco 1, Canco 2 or Geon, as the case may be,
     shall promptly assume and discharge (or reimburse the Contracting Party and
     its Affiliates for) all obligations and liabilities associated with the
     benefits of such contracts or warranties so made available to the PVC
     Partnership, the Compounding Partnership, Canco 1, Canco 2 or Geon, as the
     case may be.
 
          (d) Each Party shall keep the other Party fully informed from time to
     time as such other Party shall reasonably request as to the status of all
     Consents being sought pursuant to Section 3.4(c).
 
          (e) Each Party shall furnish to the other Party such information,
     cooperation and assistance as reasonably may be requested in connection
     with the foregoing, but nothing in this Section 3.4 shall in any way affect
     Geon's rights with respect to the Closing condition stated in Section
     4.2(g) or OCC's rights with respect to the Closing condition stated in
     Section 4.3(g).
 
          (f) Each Party shall act in good faith to complete, execute and
     deliver the Related Agreements at the Closing.
 
          (g) Each Party shall (i) fully cooperate with the other Party and its
     Affiliates in connection with the preparation of balance sheets, statements
     of income and retained earnings and statements of cash flow for such other
     Party and its Affiliates and (ii) provide the other Party and its
     Affiliates access to such Party's financial books and records and all such
     other information as may be reasonably requested by such other Party or any
     of its Affiliates in connection with the satisfaction of disclosure
     requirements under any Legal Requirement, or as may otherwise be
     appropriate or necessary.
 
     3.5 NOTIFICATIONS. Each Party shall notify the other Party and keep such
Party advised as to (i) any Proceeding that is either pending or, to its
Knowledge, threatened against such Party which challenges the transactions
contemplated hereby; (ii) any material damage to or destruction of its Subject
Business and (iii) any fact of which such Party has Knowledge that indicates
that any condition to Closing is reasonably likely not to be satisfied in a
timely fashion.
 
     3.6 PROXY STATEMENT; STOCKHOLDERS' MEETING.
 
          (a) As far in advance as is practical, Geon shall provide OCC with
     draft and final copies of all proxy statements (including, in each case,
     updates) of Geon that Geon or any of its Affiliates has prepared in
     connection with Geon obtaining stockholders' approval of the transactions
     contemplated herein and in the Related Agreements. Geon shall provide OCC
     with a reasonable opportunity to review such statements and documents and
     to object to the substance, inclusion or character of any information
     contained therein pertaining to OCC or the transactions contemplated by
     this Agreement or the Related Agreements, and Geon shall, prior to filing
     any definitive material,
                                       12
<PAGE>   218
 
     consider the revisions and corrections reasonably requested by OCC with
     respect to such statements and documents; provided, however, that OCC shall
     provide Geon with its proposed revisions and corrections to such materials
     within three Business Days after the day such materials are received by OCC
     for review. Nothing set forth herein or in the financial statements of OCC
     or any of its Affiliates provided pursuant to Section 2.1(f) or (g) shall
     be deemed to constitute the consent of Arthur Andersen LLP to the inclusion
     of the financial statements of OCC or any of its Affiliates in any of
     Geon's proxy materials or the Proxy Statement.
 
          (b) The Parties shall promptly prepare, and Geon shall promptly file
     with the SEC, the Proxy Statement in preliminary form. Geon will prepare
     the Proxy Statement and related proxy material so that it complies in all
     material respects, both as to form and substance, with the applicable
     requirements of the Exchange Act and the rules and regulations promulgated
     by the SEC thereunder. Geon will use its commercially reasonable efforts to
     respond to any comments of the SEC staff with respect thereto, in order to
     permit mailing to stockholders of the definitive Proxy Statement as
     promptly as practicable. Subject to the provisions of Section 5.1, Geon
     shall (a) call a meeting of its stockholders to be held as promptly as
     practicable after the date hereof for the purpose of voting upon the
     transfer of its Subject Business contemplated hereby, (b) through its board
     of directors, recommend to its stockholders approval of such matters and
     not rescind such recommendation except in connection with the exercise of
     Geon's right of termination under Section 5.1, (c) use commercially
     reasonable efforts to cause the Proxy Statement to be mailed to its
     stockholders at the earliest practicable date, and (d) use commercially
     reasonable efforts to obtain approval of the transfer of its Contributed
     Business contemplated hereby by its stockholders.
 
     3.7 EMPLOYEE MATTERS.
 
          (a) No later than ten days after the date of this Agreement, each
     Party will provide to the other, and will update from time to time through
     the Closing Date, a true and complete list of names, positions, salaries or
     hourly rates, as applicable, and the last bonus of each of its Employees
     and any additional information that may be reasonably necessary to assist
     in proper benefits and payroll administration. Not less than five days
     prior to the Closing Date, OCC (in the case of the PVC Partnership and
     Canco 2) and Geon (in the case of the Compounding Partnership, the
     Burlington Subject Business and the Pasadena Subject Business) shall
     identify and notify the other Party of the Employees (other than Plant
     Employees included in the OCC PVC Subject Business, the OCC Compounding
     Subject Business, the Geon PVC Subject Business, and the Geon Canada
     Subject Business, all of whom shall be offered employment by the PVC
     Partnership, Geon or Canco 2, as the case may be) to be offered employment
     by the PVC Partnership, Geon or Canco 2, as the case may be, subject to
     applicable labor law. Within two days after receiving the notice, the other
     Party may require that specific additional Employees be offered employment,
     but only if, in the reasonable opinion of such Party, the failure to offer
     employment to such specific Employees would create a material risk of
     violation of any Legal Requirement applicable to the hiring or severance of
     employees. Neither Party shall take any Anticipatory Action directed at a
     specific Employee other than a Tier 1 Employee that might prevent such
     Employee from accepting employment offered by the PVC Partnership, Geon or
     Canco 2.
 
          (b) Prior to the Closing Date, the Parties shall develop compensation,
     benefit and personnel plans, policies and programs for the employees of the
     PVC Partnership and Canco 2. Schedule 3.7(b) sets forth a summary of such
     plans, policies and programs.
 
          (c) OCC and Geon shall each pay 50% of any severance costs (i) with
     respect to Tier 2 Employees who do not become Partnership Employees and
     (ii) with respect to other Employees of OCC or Geon who (A) are terminated
     by OCC or Geon, as the case may be, in lieu of terminating specifically
     identified Tier 2 Employees, (B) are approved by the PVC Partnership (which
     approval shall not be unreasonably withheld) and (C) are terminated within
     one year of the Asset Transfer Effective Time, in each case pursuant to the
     applicable plan or program, if any, of OCC or Geon, as the case may be,
     that applies to such Employee and that is in effect as of the earlier of
     the
 
                                       13
<PAGE>   219
 
     termination date of such Employee or the Asset Transfer Effective Time
     (such costs exclude any costs associated with violations of any Legal
     Requirements).
 
     3.8 CLOSING AMENDMENTS CERTIFICATE. Not less than five Business Days prior
to the Closing Date, each of Geon and OCC shall complete and deliver to the
other an executed statement, signed by a duly authorized officer of Geon or OCC,
setting forth all amendments and additions to this Agreement or the Related
Agreements or to the schedules and exhibits hereto and thereto (if any) that (i)
such Party determines to be necessary or appropriate to complete this Agreement,
the Related Agreements and any exhibits or schedules hereto or thereto, to cure
inconsistencies or errors herein or therein, or to better reflect the intent of
the Parties hereto or the parties thereto or (ii) such Party reasonably believes
in good faith to be necessary to make the representations and warranties of its
Group contained in this Agreement or the Related Agreements true and correct in
all respects (other than such matters as are, individually and in the aggregate,
immaterial to its Subject Business) as of the Closing (such Party's "Closing
Amendments Certificate"). Each Party shall examine any such Closing Amendments
Certificate presented to it by the other Party, and if it is acceptable to such
examining Party (or if such examining Party is willing to waive the condition
that such Closing Amendments Certificate be acceptable to it), such examining
Party shall also execute it, whereupon the amendments and additions set forth
therein with respect to this Agreement and the Schedules and Exhibits hereto
shall become effective for all purposes, and the amendments and additions set
forth therein with respect to Related Agreements and the schedules and exhibits
thereto shall be effected prior to the execution and delivery thereof so as to
be effective for all purposes from and after the Closing (except to the extent
such representations and warranties relate solely to an earlier date).
 
     3.9 ENVIRONMENTAL SITE ASSESSMENTS. OCC and Geon agree that, in addition to
the rights of access provided to each Party in Section 3.1, they will jointly
retain Conestoga-Rovers & Associates, Ltd. ("Conestoga-Rovers") to perform,
prior to the Closing Date, a Phase II environmental assessment of the OCC
Compounding Subject Business, the OCC PVC Subject Business, the Geon Compounding
Subject Business, the Geon PVC Subject Business and the Geon Canada Subject
Business as necessary to reasonably determine the environmental condition
thereof immediately prior to the Closing Date. OCC and Geon shall each be
entitled to receive copies of all materials prepared by Conestoga-Rovers
pursuant to this Section 3.9, including any Phase II environmental assessments.
Notwithstanding the Closing or other termination of this Agreement, each Party
shall pay one-half of the costs and fees of Conestoga-Rovers pursuant to such
retention, except that the costs and fees of Conestoga-Rovers associated with
field work (including testing, sampling, laboratory analysis, waste disposal or
site restoration) shall be borne solely by the Party that owns, operates or
leases the property at which such field work occurs. The scope of work, budget
and schedule of Conestoga-Rovers will be determined by mutual agreement of OCC
and Geon, and may include environmental testing or sampling consistent with good
engineering practice at various locations, including testing or sampling of
ambient air, surface water, drinking water, groundwater, land surface,
subsurface strata, river sediment, natural resources and/or real property and
the physical buildings, structures and fixtures thereon, in each case if
warranted based upon the reasonable professional judgment of, and as mutually
agreed to by, OCC and Geon. After any intrusive testing or sampling,
Conestoga-Rovers shall be required, unless the Parties otherwise agree, to
remove equipment, dispose of samples, drill cuttings, purge water or other
materials used or generated in such sampling, and reasonably restore the surface
to the condition that existed prior to such testing or sampling. To the extent
practicable based upon the reasonable professional judgment of, and as mutually
agreed to by, OCC and Geon, the Parties will request that Conestoga-Rovers rely
on valid existing data rather than performing additional or duplicative
environmental testing or sampling. Each Party shall supply any such existing
data, including data subject to privileges, reasonably requested by
Conestoga-Rovers, and shall provide reasonable access during normal business
hours to the properties of its Subject Business and the representatives,
officers, employees and contractors of such Party who are involved in its
Subject Business as reasonably necessary to perform the Phase II environmental
assessment. OCC and Geon acknowledge that they are retaining Conestoga-Rovers to
assist counsel for each Party in defending against potential litigation
associated with the Subject Business, and that the retention of, and the work
product, information or data gener-
                                       14

ated by, Conestoga-Rovers shall be subject to various legal privileges,
including attorney-client privilege, self-critical analysis or environmental
audit privileges, attorney work product doctrine and joint defense privilege,
and to the Confidentiality Agreement and the Joint Defense Agreement.
 
     3.10 PROXY STATEMENT INFORMATION. If, at any time prior to the time of the
stockholders' meeting referred to in Section 2.2(f), any event with respect to
OCC, or with respect to other information supplied by OCC for inclusion in the
Proxy Statement, shall occur that is required to be described in an amendment
of, or a supplement to, the Proxy Statement, OCC shall provide such information
to Geon so that such event can be so described, and such amendment or supplement
shall be promptly filed with the SEC by Geon. If, at any time prior to the time
of said stockholders' meeting, any event with respect to Geon, or with respect
to other information supplied by Geon for inclusion in the Proxy Statement,

to, the Proxy Statement, such event shall be so described by Geon, and such
amendment or supplement shall be promptly filed with the SEC by Geon.

the contrary, if all conditions to Closing have been satisfied or waived,
excepting only the matters referred to in Section 3.12 and the receipt of the
Pedricktown Consents, then the Parties shall proceed with Closing as
contemplated by this Agreement, provided that Geon's Pedricktown, New Jersey
facility shall at Closing be leased (rather than transferred) to the PVC
Partnership pursuant to a lease that shall (i) provide for a nominal rental,
(ii) provide that it shall be terminated and such facility transferred to the
PVC Partnership promptly after the receipt of the Pedricktown Consents and (iii)
contain other terms that are mutually acceptable to the Parties.
 
     3.12 CANADA. Notwithstanding any other provision of this Agreement to the
contrary, if all conditions to Closing have been satisfied or waived, excepting

Agreement, provided that the applicable part of Geon Canada Inc.'s Niagara
Falls, Ontario facility shall at Closing be leased (rather than transferred) to

provide that it shall be terminated and such part transferred to Canco 2
promptly after the receipt of the Planning Act Consents, (iii) contain other
terms that are mutually acceptable to the Parties, and (iv) provide for a term

     3.13 PAYMENTS RELATING TO CONROE. Geon's Conroe, Texas facility is not
being contributed to the Compounding Partnership, and Geon currently anticipates
closing such facility. Provided that the Closing occurs, (i) promptly after
receipt by OCC from Geon of an invoice therefor (accompanied by supporting
documentation in reasonable detail), OCC shall pay to Geon 10% of any employee
severance costs or other out-of-pocket costs incurred by Geon in effectuating
such closure, provided that the aggregate amount paid by OCC pursuant to this
Section 3.13(i) shall not exceed $200,000, and (ii) promptly after any transfer
by Geon or any Affiliate thereof of such facility to a transferee who is not an
Affiliate of Geon, Geon shall pay to OCC 10% of the consideration received
therefor.

     transactions contemplated hereby or in the Related Agreements under the HSR

     permit or authorization in connection therewith or any other approvals or
     consents required from the Federal Trade Commission or the Justice
     Department or from the Director of Investigation and Research shall impose
     terms or conditions that would have, or would be reasonably likely to have,
     a Material Adverse Effect on any Party (assuming the Closing has taken

     frustrate the financial or other business benefits reasonably expected to
     be derived by any Party from the transactions contemplated by this
     Agreement.

     shall have been finalized and completed in a manner acceptable to each of
     Geon and OCC and their respective Affiliates, including the identity of any
     third parties involved, the terms and conditions of the relevant
     documentation, and the application and effect thereof on Geon and OCC and
     their respective Affiliates.

                           1999 INCENTIVE STOCK PLAN
 
     1.  PURPOSE. The Geon Company 1999 Incentive Stock Plan (the "Plan") is
designed to foster and promote the long-term growth and performance of the
Company by enhancing the Company's ability to attract and retain qualified
Directors and key employees and motivating Directors and key employees through
stock ownership and performance-based incentives. To achieve this purpose, this
Plan provides authority for the grant of Stock Options, Restricted Stock, Stock
Equivalent Units, Stock Appreciation Rights, Performance-Based Stock Awards, and
other stock and performance-based incentives.
 
     2.  DEFINITIONS.
 
     (a) "Affiliate" -- This term has the meaning given to it in Rule 12b-2
under the Exchange Act.
 
     (b) "Award" -- The grant of Stock Options, Restricted Stock, Stock
Equivalent Units, Stock Appreciation Rights, Performance-Based Stock Awards, and
other stock and performance-based incentives under this Plan.
 
     (c) "Award Agreement" -- Any agreement between the Company and a
Participant that sets forth terms, conditions, and restrictions applicable to an
Award.
 
     (d) "Board of Directors" -- The Board of Directors of the Company,
 
     (e) "Change of Control" -- A "Change of Control" means:
 
          (i) The acquisition by any individual, entity or group (within the
     meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of
     1934, as amended (the "Exchange Act")) (a "Person") of beneficial ownership
     (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of
     voting securities of the Company where such acquisition causes such Person
     to own 20% or more of the combined voting power of the then outstanding
     voting securities of the Company entitled to vote generally in the election
     of directors (the "Outstanding Company Voting Securities"); provided,
     however, that for purposes of this subsection (a), the following
     acquisitions shall not be deemed to result in a Change of Control: (i) any
     acquisition directly from the Company, (ii) any acquisition by the Company,
     (iii) any acquisition by any employee benefit plan (or related trust)
     sponsored or maintained by the Company or any corporation controlled by the
     Company or (iv) any acquisition by any corporation pursuant to a
     transaction that complies with clauses (i), (ii) and (iii) of subsection
     (c) below; provided, further, that if any Person's beneficial ownership of
     the Outstanding Company Voting Securities reaches or exceeds 20% as a
     result of a transaction described in clause (i) or (ii) above, and such
     Person subsequently acquires beneficial ownership of additional voting
     securities of the Company, such subsequent acquisition shall be treated as
     an acquisition that causes such Person to own 20% or more of the
     Outstanding Company Voting Securities; and provided, further, that if at
     least a majority of the members of the Incumbent Board determines in good
     faith that a Person has acquired beneficial ownership (within the meaning
     of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of the
     Outstanding Company Voting Securities inadvertently, and such Person
     divests as promptly as practicable a sufficient number of shares so that
     such Person beneficially owns (within the meaning of Rule 13d-3 promulgated
     under the Exchange Act) less than 20% of the Outstanding Company Voting
     Securities, then no Change of Control shall have occurred as a result of
     such Person's acquisition; or
 
          (ii) Individuals who, as of November 6, 1996, constitute the Board
     (the "Incumbent Board") cease for any reason to constitute at least a
     majority of the Board; provided, however, that any individual becoming a
     director subsequent to November 6, 1996 whose election, or nomination for
     election by the Company's shareholders, was approved by a vote of at least
     a majority of the directors then comprising the Incumbent Board shall be
     considered as though such individual were
                                        1

     a member of the Incumbent Board, but excluding, for this purpose, any such

     or consents by or on behalf of a Person other than the Board; or
 
          (iii) The approval by the shareholders of the Company of a
     reorganization, merger or consolidation or sale or other disposition of all
     or substantially all of the assets of the Company or the acquisition of
     assets of another corporation ("Business Combination") or, if consummation
     of such Business Combination is subject, at the time of such approval by
     shareholders, to the consent of any government or governmental agency, the
     obtaining of such consent (either explicitly or implicitly by
     consummation); excluding, however, such a Business Combination pursuant to
     which (i) all or substantially all of the individuals and entities who were
     the beneficial owners of the Outstanding Company Voting Securities
     immediately prior to such Business Combination beneficially own, directly
     or indirectly, more than 60% of, respectively, the then outstanding shares
     of common stock and the combined voting power of the then outstanding
     voting securities entitled to vote generally in the election of directors,
     as the case may be, of the corporation resulting from such Business
     Combination (including, without limitation, a corporation that as a result
     of such transaction owns the Company or all or substantially all of the
     Company's assets either directly or through one or more subsidiaries) in
     substantially the same proportions as their ownership, immediately prior to
     such Business Combination of the Outstanding Company Voting Securities,
     (ii) no Person (excluding any employee benefit plan (or related trust) of
     the Company or such corporation resulting from such Business Combination)
     beneficially owns, directly or indirectly, 20% or more of, respectively,
     the then outstanding shares of common stock of the corporation resulting
     from such Business Combination or the combined voting power of the then
     outstanding voting securities of such corporation except to the extent that
     such ownership existed prior to the Business Combination and (iii) at least
     a majority of the members of the board of directors of the corporation
     resulting from such Business Combination were members of the Incumbent
     Board at the time of the execution of the initial agreement, or of the

including the date of a Change of Control or (ii) if the Change of Control is
the result of a tender or exchange offer or a Business Combination, the highest
price per share of Common Stock paid in such tender or exchange offer or
Business Combination; provided, however, that, in the case of Incentive Stock
Options and Stock Appreciation Rights relating to Incentive Stock Options, the
Change of Control Price shall be in all cases the Fair Market Value of the
Common Stock on the date such Incentive Stock Option or Stock Appreciation Right
is exercised. To the extent that the consideration paid in any such transaction
described above consists all or in part of securities or other noncash
consideration, the value of such securities or other noncash consideration shall
be determined in the sole discretion of the Board.

                                        3
<PAGE>   239
 
to Awards granted under this Plan shall be 1,000,000 shares of Common Stock. The
assumption of awards granted by an organization acquired by the Company, or the
grant of Awards under this Plan in substitution for any such awards, will not
reduce the number of shares of Common Stock available for the grant of Awards
under this Plan.
 
     Common Stock subject to an Award that expires or is forfeited, terminated,
or canceled will again be available for grant under this Plan, without reducing
the number of shares of Common Stock available for grant of Awards under this
Plan, except to the extent that the availability of those shares of Common Stock
would cause this Plan or any Awards granted under this Plan to fail to qualify
for the exemption provided by Rule 16b-3. If a Participant pays all or part of
the exercise price of an Award by the transfer of shares of Common Stock or the
surrender (including by attestation) of all or part of an Award (including the
Award being exercised), such number of shares of Common Stock so transferred, or
the number of shares of Common Stock attributable to the portion of the Award so
surrendered, shall also be available for grant under this Plan. The number of
shares of Common Stock attributable to any Award that is settled in cash without
the actual issuance of any shares of Common Stock shall, upon such settlement,
also be available for grant under this Plan.
 
     (b) LIMITATIONS ON CERTAIN AWARDS. (i) The aggregate number of shares of
Common Stock that may be issued upon exercise of Incentive Stock Options is
1,000,000.
 
          (ii) The maximum number of shares with respect to which Options
     (including Incentive Stock Options) and Stock Appreciation Rights may be
     granted under this Plan in any period of three fiscal years to any
     individual Participant is 250,000.
 
          (iii) The aggregate number of shares of Restricted Stock (other than
     Restricted Stock which is a Performance-Based Stock Award) that may be
     awarded under this Plan is 200,000.
 
          (iv) The maximum number of shares with respect to which Options, Stock
     Appreciation Rights and Restricted Stock may be granted under this Plan in
     any one fiscal year to a Non-Employee Director is 10,000.
 
          (v) No Participant who is an employee may be awarded Performance-Based
     Stock Awards in any one fiscal year in excess of an aggregate of 50,000
     shares of Common Stock.
 
     (c) NO FRACTIONAL SHARES. No fractional shares will be issued, and the
Committee will determine the manner in which the value of fractional shares will
be treated.
 
     (d) ADJUSTMENT. In the event of any change in the number of shares of
Common Stock by reason of a merger, consolidation, reorganization,
recapitalization, or similar transaction, or in the event of a stock dividend,
stock split, or distribution to stockholders (other than normal cash dividends),
the Committee will adjust the number and class of shares that may be issued
under this Plan, the number and class of shares subject to outstanding Awards,
the exercise price applicable to outstanding Awards, and the Fair Market Value
of the shares of Common Stock and other value determinations applicable to
outstanding Awards.
 
     5.  ADMINISTRATION.
 
     (a) COMMITTEE. This Plan will be administered by the Committee. The
Committee will, subject to the terms of this Plan, have the authority to: (i)
select the eligible employees and Non-Employee Directors who will receive
Awards, (ii) grant Awards, (iii) determine the number and types of Awards to be
granted to employees and Non-Employee Directors, (iv) determine the terms,
conditions, vesting periods, and restrictions applicable to Awards, (v) adopt,
alter, and repeal administrative rules and practices governing this Plan, (vi)
interpret the terms and provisions of this Plan and any Awards granted under
this Plan, (vii) prescribe the forms of any Notices of Award, Award Agreements,
or other instruments relating to Awards, and (viii) otherwise supervise the
administration of this Plan. All decisions by the Committee will be made with
the approval of not less than a majority of its members. Except as provided in
the immediately following sentence, all decisions by the Committee will be made
 
                                        4
<PAGE>   240
 
with the approval of not less than a majority of its members. In furtherance and
not in limitation of the authority granted in clause (vi) of this paragraph, any
interpretation by a majority of the Incumbent Directors then serving on the
Committee as to whether a sale or other disposition of assets by the Company or
an acquisition of assets of another corporation constitutes a "sale or other
disposition of all or substantially all of the assets of the Company or the
acquisition of assets of another corporation" for purposes of clause (iii) of
the definition of "Change of Control" in Section 2(e) hereof shall be final and
binding for all purposes of this Plan and any Awards hereunder, notwithstanding
that the transaction in question was, or is contemplated to be, submitted to
stockholders of the Company for their approval and notwithstanding such
approval.
 
     (b) DELEGATION. The Committee may delegate any of its authority to any
other person or persons that it deems appropriate, provided the delegation does
not cause this Plan or any Awards granted under this Plan to fail to qualify for
the exemption provided by Rule 16b-3 under the Exchange Act.
 
     (c) DECISIONS FINAL. All decisions by the Committee, and by any other
person or persons to whom the Committee has delegated authority, will be final
and binding on all persons.
 
     6.  AWARDS.
 
     (a) GRANT OF AWARDS. The Committee will determine the type or types of
Awards to be granted to each Participant and will set forth in the related
Notice of Award or Award Agreement the terms, conditions, vesting periods, and
restrictions applicable to each Award. Awards may be granted singly or in
combination or tandem with other Awards, except to the extent that any grants in
combination or tandem would impair the exemption for performance based
compensation provided for under Section 162(m). Awards may also be granted in
replacement of, or in substitution for, other awards granted by the Company,
whether or not granted under this Plan, except that, with respect to
Performance-Based Stock Awards, the new Award must also be wholly contingent on
the attainment of performance goals established by the Committee; without
limiting the foregoing, if a Participant pays all or part of the exercise price
or taxes associated with an Award by the transfer of Common Stock or the
surrender of all or part of an Award (including the Award being exercised), the
Committee may, in its discretion, grant a new Award (which, in the case of
Awards intended to replace Performance-Based Stock Awards, must also be wholly
contingent on the attainment of performance goals established by the Committee)
to replace the shares of Common Stock that were transferred or the Award that
was surrendered. The Company may assume awards granted by an organization
acquired by the Company or may grant Awards in replacement of, or in
substitution for, any such awards.
 
     (b) TYPES OF AWARDS. Awards may include, but are not limited to, the
following:
 
          (i) STOCK APPRECIATION RIGHT -- A right to receive a payment, in cash
     or Common Shares, equal to the excess of (A) the Fair Market Value of a
     specified number of shares of Common Stock on the date the right is
     exercised over (B) the Fair Market Value on the date the right is granted.
     The right may be conditioned upon the occurrence of certain events, such as
     a Change of Control of the Company, or may be unconditional, as determined
     by the Committee.
 
          (ii) STOCK AWARD -- An Award that is made in Common Stock, Restricted
     Stock, or Stock Equivalent Units or that is otherwise based on, or valued
     in whole or in part by reference to, the Common Shares, including
     Performance-Based Stock Awards. All or any part of any Stock Award may be
     subject to such conditions, restrictions, and risks of forfeiture, as and
     to the extent established by the Committee and, with respect to
     Performance-Based Stock Awards, such conditions and restrictions as may be
     required under Section 162(m), so that the Performance-Based Stock Awards
     constitute performance-based compensation thereunder. Stock Awards may be
     based on the Fair Market Value of the Common Stock, or on other specified
     values or methods of valuation, as determined by the Committee.
 
          (iii) STOCK OPTION -- A right to purchase a specified number of shares
     of Common Stock, during a specified period, and at a specified exercise
     price, all as determined by the Committee. A
 
                                        5
<PAGE>   241
 
     Stock Option may be an Incentive Stock Option or a Stock Option that does
     not qualify as an Incentive Stock Option (a "non-qualified Stock Option").
     In addition to the terms, conditions, vesting periods, and restrictions
     established by the Committee, Incentive Stock Options must comply with the
     requirements of Section 422 of the Code. The exercise price of a Stock
     Option, including a non-qualified Stock Option, may be no less than the
     Fair Market Value of the Common Shares on the date the Stock Option is
     granted.
 
          (v) PERFORMANCE-BASED STOCK AWARDS -- A Stock Award granted to a
     Participant pursuant to Section 7.
 
     7.  PERFORMANCE-BASED STOCK AWARDS.
 
     The Committee may, in its discretion, grant Stock Awards valued by
reference to shares of Common Stock that are wholly contingent on the attainment
of performance goals established by the Committee from time to time. The
performance goals will relate to one or more of the following performance
measures, as determined by the Committee for each applicable performance period:
(i) return to stockholders, (ii) cash flow, (iii) return on equity, (iv) Company
created income (for example, income due to Company initiated cost reductions or
productivity improvements), (v) sales growth, (vi) earnings and earnings growth,
(vii) return on assets, (viii) stock price, (ix) earnings per share, (x) market
share, (xi) customer satisfaction, and (xii) safety and/or environmental
performance. Any such performance goals and the applicable performance measures
will be determined by the Committee at the time of grant and reflected in a
written award agreement. The foregoing performance goals and performance
criteria shall have any reasonable definitions that the Committee may specify,
which may include or exclude any or all of the following items, as the Committee
may specify: extraordinary, unusual or non-recurring items; effects of
accounting changes; effects of currency fluctuations; effects of financing
activities (e.g., effect on earnings per share of issuing convertible debt
securities); expenses for restructuring or productivity initiatives;
non-operating items; acquisition expenses (e.g., pooling of interests); and
effects of divestitures. Any such performance goals or combination of such goals
may apply to the Participant's Performance-Based Stock Award in its entirety or
to any designated portion or portions of the Performance-Based Stock Award, as
the Committee may specify. The number or value of Performance-Based Stock Awards
that will be paid out to any Participant at the end of the applicable
performance period, which may be one year or longer as determined by the
Committee, will depend on the extent to which the Company attains the
established performance goals.
 
     8.  DEFERRAL OF PAYMENT.
 
     With the approval of the Committee, the delivery of the Common Stock, cash,
or any combination thereof subject to an Award may be deferred, either in the
form of installments or a single future delivery. The Committee may also permit
selected Participants to defer the payment of some or all of their Awards, as
well as other compensation, in accordance with procedures established by the
Committee to assure that the recognition of taxable income is deferred under the
Code. Deferred amounts may, to the extent permitted by the Committee, be
credited as cash or Stock Equivalent Units. The Committee may also establish
rules and procedures for the crediting of interest on deferred cash payments and
dividend equivalents on Stock Equivalent Units.
 
     9.  PAYMENT OF EXERCISE PRICE. The exercise price of a Stock Option and any
Stock Award for which the Committee has established an exercise price may be
paid in cash, by the transfer of Common Stock, by the surrender of all or part
of an Award (including the Award being exercised), or by a combination of these
methods, as and to the extent permitted by the Committee. The Committee may
prescribe any other method of paying the exercise price that it determines to be
consistent with applicable law and the purpose of this Plan.
 
     In the event shares of Restricted Stock are used to pay the exercise price
of a Stock Award, a number of the shares of Common Stock issued upon the
exercise of the Award equal to the number of
 
                                        6
<PAGE>   242
 
shares of Restricted Stock used to pay the exercise price will be subject to the
same restrictions as the Restricted Stock.
 
     10.  TAXES ASSOCIATED WITH AWARD. Prior to the payment of an Award, the
Company may withhold, or require a Participant to remit to the Company, an
amount sufficient to pay any Federal, state, and local taxes associated with the
Award. The Committee may, in its discretion and subject to such rules as the
Committee may adopt, permit a Participant to pay any or all taxes associated
with the Award in cash, by the transfer of Common Stock, by the surrender of all
or part of an Award (including the Award being exercised), including
Performance-Based Stock Awards, or by a combination of these methods. The
Committee may permit a Participant to pay any or all taxes associated with an
Incentive Stock Option in cash, by the transfer of Common Stock, or by a
combination of these methods.
 
     11.  TERMINATION OF EMPLOYMENT. Subject to Section 12, if the employment of
a Participant terminates for any reason, all unexercised, deferred, and unpaid
Awards may be exercisable or paid only in accordance with rules established by
the Committee. Subject to the foregoing exception, these rules may provide, as
the Committee deems appropriate, for the expiration, continuation, or
acceleration of the vesting of all or part of the Awards.
 
     12.  CHANGE OF CONTROL. In the event of a Change of Control of the Company,
unless and to the extent otherwise determined by the Board of Directors, (i) all
Stock Appreciation Rights and Stock Options then outstanding will become fully
exercisable as of the date of the Change of Control and (ii) all restrictions
and conditions applicable to Restricted Stock and other Stock Awards, including
Performance-Based Stock Awards, will be deemed to have been satisfied as of the
date of the Change of Control. Any such determination by the Board of Directors
that is made after the occurrence of a Change of Control will not be effective
unless a majority of the Directors then in office are Continuing Directors and
the determination is approved by a majority of the Continuing Directors.
 
     Notwithstanding any other provision of this Plan, during the 60-day period
from and after a Change of Control (the "Exercise Period"), unless the Committee
shall determine otherwise at the time of grant, an optionee shall have the
right, whether or not the Stock Option is fully exercisable and in lieu of the
payment of the exercise price for the shares of Common Stock being purchased
under the Stock Option and by giving notice to the Company, to elect (within the
Exercise Period) to surrender all or part of the Stock Option to the Company and
to receive cash, within 30 days of such notice, in an amount equal to the amount
by which the Change of Control Price per share of Common Stock on the date of
such election shall exceed the exercise price per share of Common Stock under
the Stock Option (the "Spread") multiplied by the number of shares of Common
Stock granted under the Stock Option as to which the right granted under this
Section shall have been exercised.
 
     13. AMENDMENT, SUSPENSION, OR TERMINATION OF THIS PLAN; AMENDMENT OF
         OUTSTANDING AWARDS.
 
     (a) AMENDMENT, SUSPENSION, OR TERMINATION OF THIS PLAN. The Board of
Directors may amend, suspend, or terminate this Plan at any time. Stockholder
approval for any such amendment will be required only to the extent necessary to
preserve the exemption provided by Rule 16b-3 for this Plan and Awards granted
under this Plan.
 
     (b) AMENDMENT OF OUTSTANDING AWARDS. The Committee may, in its discretion,
amend the terms of any Award, including, waiving, in whole or in part, any
restrictions or conditions applicable to, or accelerating the vesting of, any
Award, prospectively or retroactively, but no such amendment may impair the
rights of any Participant without his or her consent or cause Awards intended to
qualify as performance based compensation under Section 162(m) to fail to so
qualify.
 
     14.  AWARDS TO FOREIGN NATIONALS AND EMPLOYEES OUTSIDE THE UNITED
STATES. To the extent that the Committee deems appropriate to comply with
foreign law or practice and to further the purpose
 
                                        7
<PAGE>   243
 
of this Plan, the Committee may, without amending this Plan, (i) establish
special rules applicable to Awards granted to Participants who are foreign
nationals, are employed outside the United States, or both, including rules that
differ from those set forth in this Plan, and (ii) grant Awards to such
Participants in accordance with those rules.
 
     15.  NONASSIGNABILITY. Unless otherwise determined by the Committee, (i) no
Award granted under this Plan may be transferred or assigned by the Participant
to whom it is granted other than by will, pursuant to the laws of descent and
distribution, or pursuant to a qualified domestic relations order and (ii) an
Award granted under this Plan may be exercised, during the Participant's
lifetime, only by the Participant or by the Participant's guardian or legal
representative; except that, no Incentive Stock Option may be transferred or
assigned pursuant to a qualified domestic relations order or exercised, during
the Participant's lifetime, by the Participant's guardian or legal
representative.
 
     16.  GOVERNING LAW. The interpretation, validity, and enforcement of this
Plan will, to the extent not governed by the Code or the securities laws of the
United States, be governed by the laws of the State of Ohio.
 
     17.  RIGHTS OF EMPLOYEES. Nothing in this Plan will confer upon any
Participant the right to continued employment by the Company or limit in any way
the Company's right to terminate any Participant's employment at will.
 
     18.  EFFECTIVE AND TERMINATION DATES.
 
     (a)  EFFECTIVE DATE. This Plan will become effective on the date it is
approved by the stockholders.
 
     (b)  TERMINATION DATE. This Plan will continue in effect until terminated
by the Board of Directors.
