ITEM 1. BUSINESS.

INTRODUCTION

     OMNOVA Solutions Inc. (Omnova Solutions) was organized in June 1999 as a
wholly owned subsidiary of GenCorp Inc. Subject to the satisfaction or waiver of
certain conditions:

        - GenCorp will contribute to Omnova Solutions GenCorp's Performance
          Chemicals and Decorative & Building Products businesses and some other
          corporate assets in exchange for shares of Omnova Solutions common
          stock and Omnova Solution's assumption of liabilities related to those
          businesses and assets; and

        - GenCorp will declare and pay as a special dividend to the holders of
          its common stock, on a pro rata basis, all of the outstanding shares
          of capital stock of Omnova Solutions.

The foregoing transactions are referred to as the Distribution.

     The Distribution is conditioned upon, among other things:

        - approval of the Distribution by holders of at least a majority of the
          outstanding GenCorp common stock;

        - the effectiveness of this Registration Statement on Form 10; and

        - there not being in effect any statute, rule, regulation or order of
          any court, governmental or regulatory body that prohibits or makes
          illegal the transactions contemplated by the Distribution.

The Distribution will not occur if the conditions described above are not
satisfied.

     The GenCorp Board has retained discretion, even if all conditions to the
Distribution are satisfied, to abandon, defer or modify the Distribution.

     Prior to the date of the special dividend contemplated by the Distribution,
GenCorp will transfer to Omnova Solutions the assets associated with the
Performance Chemicals and Decorative & Building Products businesses, and some
other corporate assets. These assets will include (1) the GenCorp Technology
Center, (2) GenCorp's corporate flight operations, (3) GenCorp's corporate
headquarters building in Fairlawn, Ohio and (4) the tangible and intangible
assets owned and leased for the Performance Chemicals and Decorative & Building
Products businesses. Omnova Solutions intends to dispose of the corporate flight
operations within a reasonable period after the Distribution. In exchange for
the assets transferred, Omnova Solutions will issue to GenCorp a number of
shares of Omnova Solutions common stock equal to the number of shares of GenCorp
common stock outstanding on the record date for the special dividend and assume
liabilities of GenCorp relating to the businesses and assets transferred.


     In August 1999, Omnova Solutions pre-closed a credit agreement with Bank of
America. The credit agreement will provide $300 million of available credit on a
five-year revolving basis. Immediately prior to the Distribution, Omnova
Solutions will borrow approximately $188 million under the credit agreement. At
the same time, Omnova Solutions will declare and distribute to GenCorp a special
dividend in the amount of approximately $188 million. Omnova Solutions expects
to use funds borrowed under the credit agreement to pay the special dividend to
GenCorp. GenCorp will use the special dividend to repay indebtedness. The
purpose of this special dividend to GenCorp is to allocate GenCorp's
indebtedness between the businesses of Omnova Solutions and the businesses to be
retained by GenCorp. The actual amount to be borrowed by Omnova Solutions and
distributed to GenCorp will be determined at the time of the Distribution.


BACKGROUND

     Following the Distribution, Omnova Solutions will operate two business
segments, Performance Chemicals and Decorative & Building Products. Omnova
Solutions had pro forma revenues of approximately $766 million for the fiscal
year ended November 30, 1998. Information regarding revenues, operating profits
and assets

<PAGE>   3

attributable to the two segments are contained in Omnova Solutions' audited and
unaudited combined financial statements included in this Form 10.

     The Performance Chemicals business was founded in 1952 as a segment of The
General Tire & Rubber Company, GenCorp's predecessor, focusing primarily on the
manufacture of latex, an emulsion polymer, for the paper industry and tire cord
adhesives in its Mogadore, Ohio facility. During the 1960's, the segment began
expanding its product lines for the paper and carpet industries, and in 1993
opened a latex plant in Green Bay, Wisconsin to better serve the needs of its
paper customers in the Upper Midwest. The Decorative & Building Products segment
began in 1945 when The General Tire & Rubber Company purchased the Jeannette,
Pennsylvania coated fabric facility from the Pennsylvania Rubber Company. In
1963 the Company built a production facility in Columbus, Mississippi to
increase its capacity and product offering in coated fabrics.

     Since the early 1990's, GenCorp has aggressively grown both businesses. For
Performance Chemicals, the 1996 acquisition of Morton International's Lytron(R)
plastic pigment latex product line broadened offerings to the paper industry.
The 1998 acquisition of Goodyear's Calhoun, Georgia latex facility provided
additional manufacturing capacity, a strong presence in the southeast and an
expanded customer base. Performance Chemicals also acquired Sequa Chemical's
U.S. specialty chemicals business in 1998, gaining manufacturing facilities in
Chester, South Carolina and Greensboro, North Carolina. This acquisition
expanded existing emulsion polymer market positions and provided entry into new
related specialty chemical markets. The 1999 acquisition of PolymerLatex's U.S.
acrylics business in Fitchburg, Massachusetts provided a key northeast location
while strengthening and diversifying served markets in acrylic emulsions and
other specialty chemicals. The most recent 1999 acquisition of Morton
International's global latex floor care business has provided Performance
Chemicals with a new and complementary product line and new customers, based on
existing technology. Performance Chemicals holds a strong number two market
position in the styrene butadiene latex industry. The number of Performance
Chemicals facilities has grown from two to six in the past few years, with
estimated available served markets growing from $1 billion to $3.5 billion.

     Decorative & Building Products expanded its commercial wallcovering
capabilities in 1991 through the acquisition of Canadian General Towers'
commercial wallcovering business. Today, with the recent acquisition of Walker
Greenbank's U.K.-based Muraspec and Brymor commercial wallcovering businesses,
Decorative & Building Products has grown to be the worldwide leader in this
market. Brymor provides a European manufacturing base. Muraspec, a distribution
business with sales offices throughout the U.K. and Europe, serves as a key
European distribution platform from which to market commercial wallcoverings and
other decorative and building products. GenCorp acquired Goodyear's Reneer Films
Division in 1993, increasing vinyl film and decorative laminate capability for
the Decorative & Building Products business and elevating its market position in
vinyl woodgrain laminates to number one in North America. In 1997, Decorative &
Building Products acquired the Printworld business of Technographics, Inc.,
adding paper laminates to its vinyl laminate portfolio and gaining entry into
the transfer printing market for furnishings and apparel.

     Omnova Solutions had approximately 2,600 employees at May 31, 1999 located
at offices, plants and other facilities located principally throughout the
United States and the United Kingdom.

     Omnova Solutions has been, and will be until the date of the special
dividend contemplated by the Distribution, a wholly owned subsidiary of GenCorp.
Omnova Solutions' principal executive offices are located at 175 Ghent Road,
Fairlawn, Ohio 44333. Its telephone number at that address is (330) 869-4200.

GENERAL

     Omnova Solutions develops, manufactures and markets emulsion polymers,
specialty chemicals and decorative and building products for a variety of
industrial, commercial and consumer markets. The Performance Chemicals unit's
broad range of emulsion polymers and specialty chemicals are used as coatings,
binders, adhesives, and additives for paper, carpet, textile and various other
industries. Decorative & Building Products designs, manufactures and markets a
comprehensive line of polyvinyl chloride and paper-based decorative and
performance-enhancing surface products including wallcovering, coated fabrics,
vinyl woodgrain and paper laminates and graphic arts and industrial films, as
well as membrane systems for roofing. Markets served include furniture,
transportation, construction, remodeling, interior decorating and graphic arts.

                                        3
<PAGE>   4

     Of Omnova Solutions' 1998 historical revenues, approximately 36% were
derived from the Performance Chemicals business and 64% from the Decorative &
Building Products business.

PRODUCTS AND SERVICES

  PERFORMANCE CHEMICALS

     Performance Chemicals manufactures a broad line of emulsion polymers and
specialty chemicals for use in the paper, carpet, textile, nonwoven,
construction, coatings, adhesive and tire cord industries. Performance
Chemicals' products for the paper industry improve the strength, gloss and
printability of its customers' products. These products are primarily used in
the manufacture of coated papers for applications such as magazines, photo
papers and office forms. Paper coatings represented 15.9%, 17.9% and 18.0% of
Omnova Solutions' consolidated revenues for fiscal 1998, 1997 and 1996,
respectively. Latex formulations are also used to provide these same
characteristics to paperboard packaging for food and household products. The
business is also a leading producer of styrene butadiene latex for use as carpet
backing adhesive, which secures carpet fibers to backing materials. Through the
1998 acquisition of Sequa Chemicals, Performance Chemicals significantly
expanded its product line breadth to include specialty wet end formulations such
as opacifiers, lubricants and insolubilizers used in paper manufacturing. The
acquisition significantly expanded total product offerings to paper customers
and enabled Performance Chemicals to generate significant synergies through
consolidated purchasing of acrylic monomers, cross selling of textile and carpet
chemicals and enhanced applications development. Additionally, the acquisition
added a diverse line of textile processing, coating and finishing chemicals that
provide water, stain and oil repellency and permanent press properties to
natural and synthetic textile fibers for apparel, home furnishings and
upholstery.

     Performance Chemicals' product portfolio includes a growing specialty
segment that provides resins, binders, coatings, adhesives and saturants to a
broad variety of markets that include nonwoven, graphic arts, industrial
coatings and construction. These products provide greater strength, improved
processing ability and enhanced appearance for customer products.

     With a strong number two position in the latex industry, Performance
Chemicals is recognized in all of its markets for its core capabilities in
polymer technology, its ability to rapidly develop highly customized products
and its ability to provide innovative, cost effective customer solutions.

  DECORATIVE & BUILDING PRODUCTS

     Decorative & Building Products believes that it is recognized in the
industry as a leading supplier of decorative surfacing laminates for wood and
metal applications and that it holds the number one North American position in
combined paper and vinyl woodgrain laminates. Decorative laminate products are
manufactured utilizing vinyls, lightweight papers and foils. Unique ultraviolet
(UV) and electronic beam (EB) coatings provide scratch, stain and UV resistance.
In addition, Decorative & Building Products has further differentiated itself in
the decorative laminate market as a single source supplier of integrated vinyl
and paper laminate designs for the furniture and cabinet industries, building an
extensive library of patterns, designs and textures and developing rapid
make-to-order production capabilities. Important markets for these products
include furniture, kitchen cabinets, manufactured housing, flooring laminates,
consumer electronics and wrapped wood components. In particular, the growing
ready-to-assemble furniture market provides an attractive market for Omnova
Solutions' unique decorative laminates product offerings. Double polished clear
vinyl films for the graphic arts, office products and stationery markets are
also produced. Decorative laminates represented 11.9%, 10.5% and 10.5% of Omnova
Solutions' consolidated revenues for fiscal 1998, 1997 and 1996, respectively.

     Decorative & Building Products is the leading global manufacturer of
wallcoverings for the commercial market. Its product line includes a broad range
of fabric-backed vinyl and paper-backed vinyl wallcovering designs. Its industry
leading styling and design library covers a broad range of styles, patterns,
textures, and colors, ranging from traditional to contemporary designs.
Additionally, Decorative & Building Products has built its leading position in
the commercial wallcoverings market by leveraging its reputation for product
durability and quality, global distribution network, extensive emboss and print
roll library, long-term customer relationships, and integrated
manufacturing/distribution/sourcing value proposition. Well-known brands include
Bolta(R),

                                        4
<PAGE>   5

Essex(R), Genon(R), Lanark(R), Tower(TM) and X-Quest(R) in North America and
Muralon and Muraspec in Europe. Key end user markets include the hospitality,
healthcare, commercial office and retail industries. Commercial wallcoverings
represented 15.9%, 18.9% and 17.5% of Omnova Solutions' consolidated revenues
for fiscal 1998, 1997 and 1996, respectively.

     Based on industry data and information, Decorative & Building Products
believes that it is the leading North American supplier of vinyl coated fabrics
and urethane fabrics for contract and residential home furnishings,
transportation seating and marine applications as well as a variety of other
industrial and commercial end use markets. Its coated fabrics are durable, stain
resistant and cost effective alternatives and complements to leather and textile
coverings. Competitive advantages in the coated fabric industry are leveraged
through creative design and styling capabilities, performance enhancing
coatings, innovative technical support programs, leading brand names and
established distribution channels. Coated fabrics represented 12.0%, 13.1% and
13.1% of Omnova Solutions' consolidated revenues for fiscal 1998, 1997 and 1996,
respectively.


     Decorative & Building Products is also a leading North American
manufacturer and marketer of single-ply roofing membrane systems for the
commercial and industrial roofing market. Selling under the Genflex(TM) brand
name, it was the first in the industry and is one of only two North American
single-ply roofing suppliers that offer all three single-ply roofing systems,
EPDM, TPO and PVC. This allows for a tailored solution for each type of roofing
application requirement. Through the introduction of innovative products,
Decorative & Building Products has developed programs that reduce the time and
cost of installation. Building systems represented 12.9%, 13.1% and 11.6% of
Omnova Solutions' consolidated revenues for fiscal 1998, 1997 and 1996,
respectively.


     Through its Printworld operations, Decorative & Building Products
manufactures heat transfer prints on paper used to decorate apparel and home
furnishings. Heat transfer printing is an innovative, unique process for
printing intricate patterns on natural and synthetic fabrics that can be used
widely in the home furnishing, commercial furnishing and apparel industries.

     Decorative & Building Products has established leading market positions in
all of its product categories by utilizing the Company's core competencies in
design, compounding, calendering, printing, embossing and coating. Given similar
core competencies and base technology requirements, the business is able to
leverage its investments in manufacturing, process and design improvement across
this broad set of product lines and benefit from economies of scale. In
addition, its broad offering of decorative and building products uniquely
positions it to provide integrated decorative solutions for its customers.

BUSINESS STRATEGY

     ORGANIC GROWTH BY PROVIDING TOTAL SOLUTIONS. Omnova Solutions intends to
grow organically by developing long-term customer relationships and positioning
itself as the preferred total solutions partner. Omnova Solutions' strategy is
to avoid commodity market segments and focus on products that are highly
customized to meet specific customer requirements. These relationships have
enabled Omnova Solutions to develop innovative products that provide superior
functional performance, higher decorative content, and more efficient, lower
cost production processes to meet customers' specific application needs and
enhance the value of their products. For example, new roofing system
developments have provided significant benefits to contractors and building
owners by substantially reducing installation time and labor costs.

     PURSUE GROWTH THROUGH STRATEGIC ACQUISITIONS. Omnova Solutions' businesses
have achieved significant growth through acquisitions of companies that build on
existing markets and core product and process technologies. Omnova Solutions
plans to continue to pursue acquisitions, strategic partnerships and joint
ventures in the future, targeting technologies and products in high growth
markets that are strategically related to its existing product portfolio,
customer base and markets.

     LEVERAGE CORE COMPETENCIES ACROSS BUSINESSES. Omnova Solutions' expertise
in high performance polymer-based chemistries, the design and development of
customized product applications and polymer processing capabilities are shared
across its business units and provide a unique and differentiating competitive
advantage. Performance Chemicals and Decorative & Building Products have
identified common growth platforms to capitalize on these technology linkages.
For example, Performance Chemicals has pursued the

                                        5
<PAGE>   6

development and commercialization of new polymer and specialty chemical
additives to meet the needs of its broadening market portfolio. These new
formulations in advanced coatings, inks and adhesives are beginning to be
leveraged in the Decorative & Building Products segment to enhance the
performance of a number of its products. Omnova Solutions' aligned growth
strategy targets opportunities for both businesses to team as customers or
suppliers in the paper, textile, carpet, furniture and construction industries.

     EXPAND STRONG RESEARCH AND DESIGN CAPABILITIES. Omnova Solutions is an
industry leader in research and development, as well as styling and design
capabilities. The Performance Chemicals segment has recently made a major
investment in a new high speed pilot paper coater, which will be used to
accelerate Omnova Solutions' development and commercialization of new coating
technologies in its core markets. Omnova Solutions started construction of a new
pilot plant in 1998, which will support Omnova Solutions' new product
development and customer qualifications efforts. The Decorative & Building
Products segment maintains design centers in Salem, New Hampshire, New York and
Hertfordshire, England where designers combine traditional design techniques
with state-of-the-art computer aided design equipment to create unique designs
for incorporation across Omnova Solutions' decorative product spectrum. Omnova
Solutions continues to strengthen its design capability through investments in
digital archiving of designs and digital sampling. In addition, the business has
increased its focus on technology and new product development to provide
differentiated value-added products to customers.

     INCREASE TECHNOLOGY LINKAGES. Through increasing technology linkages and
materials utilization between the two segments, Omnova Solutions can
aggressively pursue the development and commercialization of new polymers as
well as the function and performance of its decorative coatings. These technical
and materials synergies allow Performance Chemicals and Decorative & Building
Products to target and expand key markets. Technological linkages, purchasing,
marketing and sales economies, and manufacturing economies will enable more cost
effective development of new products and will increase the effectiveness of
cost reduction initiatives at Omnova Solutions. For example, the Omnova
Solutions business units have a powerful collective knowledge base in paper,
nonwovens, textiles, printing technology, ink systems and performance coatings,
and the chemicals application skills to supply advantaged products for these
applications.

     BROADEN INTERNATIONAL OPERATIONS. Omnova Solutions plans to continue to
increase its global supply capabilities and the markets it serves. For example,
the recent acquisition of the Brymor and Muraspec U.K.-based commercial
wallcovering business provided a European manufacturing, design and distribution
platform for the Decorative & Building Products segment. The Company is
committed to continuing to expand its international presence through a continued
aggressive acquisition, joint venture and alliance strategy.

     IMPROVE PROFITABILITY THROUGH OPERATIONAL EXCELLENCE
INITIATIVES. Operational excellence processes including Six Sigma quality,
supply chain management and high performance workplace initiatives are utilized
throughout Omnova Solutions' businesses. Omnova Solutions plans to continue to
focus on operational excellence initiatives across the supply chain to drive
improvements in productivity, quality cost and safety.

MARKETS AND CUSTOMERS

     Management believes that Performance Chemicals is a market leader in its
targeted product categories. The polymer and chemical coating and binding
markets are highly competitive based on price, quality, customer service,
product performance and innovations. Performance Chemicals is the leading
quality producer for latex in the paper industry. Major customers include
industry leaders such as Champion, Shaw and Consolidated.

     Management believes that Decorative & Building Products is a market leader
in its targeted product categories. Decorative & Building Products markets are
competitive based on decorative content, enhanced performance characteristics,
price, quality, customer service, brand name recognition and reputation.
Decorative & Building Products markets its products under numerous brand names
to different industries. Major customers of this unit are Steelcase, Bradco and
Ashley Furniture.

                                        6
<PAGE>   7

DISTRIBUTION METHODS

     Methods of distribution used by Omnova Solutions vary widely depending on
the nature of the products and the industry or market served. Products are sold
either directly or through distributors.

COMPETITION

     Performance Chemicals competes with several large global chemical companies
including Dow, BASF and Rohm & Haas, some of which produce rather than buy major
raw materials. Performance Chemicals also competes with small to mid-sized
U.S.-focused suppliers of specialty chemicals including B.F. Goodrich, National
Starch, S. C. Johnson Polymers and Morton International. Depending on the
products involved and markets served, the basis of competition varies from
price, quality, customer and technical service, product performance and
innovation, and industry recognition. Overall, Performance Chemicals regards its
products to be competitive in its major markets and believes that it holds
leading or strong number two positions in several North American markets
including paper coatings, styrene butadiene latex carpet backing binders,
textile permanent press resins, nonwoven binders, paper tape release coatings
and saturants, and tire cord adhesives.

     Decorative & Building Products competes in its served markets with numerous
competitors, many of which are smaller and privately-owned. Key competitors in
each product group include:

     - Commercial wallcovering -- RJF International, Fidelity Paint Systems

     - Coated fabrics -- Haartz and Uniroyal

     - Decorative laminates -- Chiyoda, Dai Nippon and Toppan

     - Building systems -- Carlisle, Firestone, and Manville

     - Heat transfer printing -- Miroglio, Sublistatic and Transfertex

INTELLECTUAL PROPERTY

     Omnova Solutions regards its patents, copyrights, trademarks, and similar
intellectual property as important to its success and relies upon patent,
copyright and trademark laws, as well as confidentiality agreements with its
employees and others, to protect its rights. Omnova Solutions pursues patents
for important developments and the registration of its important copyrights and
trademarks in the United States and, depending upon use, in other countries.

     Omnova Solutions may be subject to claims of alleged infringement of the
patents, trademarks and other intellectual property rights of third parties from
time to time in the ordinary course of business. Omnova Solutions does not
believe that these legal proceedings or claims are likely to have, individually
or in the aggregate, a material adverse effect on Omnova Solutions' business,
financial condition or results of operations.

RAW MATERIALS

     Performance Chemicals utilizes a variety of raw materials, primarily
monomers, in the manufacture of its products, all of which are generally
available from several qualified suppliers. Monomer costs are a major component
of the emulsion polymers produced by the business. The monomers used include
styrene, butadiene, acrylonitrile, hydroxyethyl acrylate, vinylpyridine,
vinylidiene chloride, acrylic acid, methacrylic acid, itaconic acid, vinyl
acetate, butyl acrylate, ethyl acrylate, methyl methacrylate, acrylamide,
n-methyol methacrylamide, acrylamide, and hydroxyethyl methacrylate.

     Decorative & Building Products also utilizes a variety of raw materials
which are generally available from multiple suppliers. Key raw materials include
polyvinyl chloride resins, textiles, plasticizers, paper, and titanium dioxide.
Textiles and polyvinyl chloride resins represent approximately 47% of total raw
materials purchased on a dollar basis.

     The cost of these raw materials has a significant impact on Omnova
Solutions' profitability. A significant increase in the price of monomers or
polyvinyl chloride resins could materially increase Omnova Solutions' operating
costs and materially adversely affect its profit margins. While Omnova Solutions
generally attempts to

                                        7
<PAGE>   8

pass increased raw materials prices onto its customers in the form of price
increases, there has historically been a time delay between increased raw
materials prices and the ability to increase product prices. In addition, Omnova
Solutions may not be able to increase its prices sufficiently to cover any
significant raw materials cost increases.

ENVIRONMENTAL MATTERS

     The business operations of Omnova Solutions, like those of other companies
in the industries in which Omnova Solutions operates, are subject to numerous
foreign, federal, state and local environmental laws and regulations. These laws
and regulations not only affect Omnova Solutions' current operations, but also
could impose liability on Omnova Solutions for past operations that were
conducted in compliance with then applicable laws and regulations. Omnova
Solutions anticipates that these laws and regulations will become increasingly
stringent. Environmental liabilities related to discontinued operations will not
be assumed by Omnova Solutions and will remain obligations of GenCorp after the
Distribution.

EMPLOYEES

     Omnova Solutions will employ approximately 2,600 employees after the
Distribution. Approximately 28% of these employees will be covered by collective
bargaining agreements. A prolonged work stoppage at any of Omnova Solutions'
facilities could materially adversely affect Omnova Solutions' business and
results of operations.

ITEM 2. FINANCIAL INFORMATION.

OMNOVA SOLUTIONS SELECTED HISTORICAL FINANCIAL DATA

     The financial data as of November 30, 1997 and 1998 and for each of the

       profit, related to exiting the residential wallcovering business. This
       unusual expense was subsequently adjusted to $3 million in the fourth
       quarter.

OMNOVA SOLUTIONS MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

OVERVIEW

     Since 1994, GenCorp's key strategy has been to become a more focused
company in fewer businesses. The businesses targeted were those with the
greatest potential to generate value from continuing improved performance and
expansion in existing markets, and through enhanced growth by entering
attractive new and

                                        9
<PAGE>   10

related markets. On December 17, 1998, GenCorp announced its plans to spin off
its Performance Chemicals and Decorative & Building Products businesses to
GenCorp shareholders as a separate publicly traded polymer products company
(Omnova Solutions).

     Omnova Solutions will operate two business segments, Performance Chemicals
and Decorative & Building Products. The Performance Chemicals unit manufactures
a broad range of emulsion polymers and specialty chemicals used as coatings,
binders, adhesives, and additives for paper, carpet, textile and various other
specialty chemical industries. Decorative & Building Products designs,
manufactures and markets a comprehensive line of polyvinyl chloride and
paper-based decorative and functional surface products including wallcovering,
coated fabrics and vinyl woodgrain and paper laminates for furniture,
construction, remodeling and other commercial applications, as well as membrane
systems for roofing.

     Omnova Solutions' sales are affected by numerous factors. In the
Performance Chemicals business, the key sales drivers are the ability to create
custom polymer and specialty chemical solutions to enhance customer product
performance; domestic demand for coated paper; and trends in the carpet,
textile, and specialty markets. In the Decorative & Building Products business,
commercial wallcovering and building systems sales are driven by trends in
refurbishment of commercial office buildings, hotels, hospitals and schools and,
to a lesser degree, new construction cycles. Product design and styling are
important product differentiators in the commercial wallcovering business. Sales
trends in decorative laminates and coated fabrics typically move with general
economic trends, with slightly greater growth due to the business units' ability
to produce enhanced designs and styles to meet the needs of commercial and
residential furniture customers. Omnova Solutions is subject to volatility in
its operating costs arising from changes in the price of several key raw
materials including polyvinyl chloride, styrene and butadiene.

     Omnova Solutions' annual sales have grown from $479 million in 1994 to $624
million in 1998. During the same period, Omnova Solutions' segment operating
profit doubled from $40 million to $83 million. Omnova Solutions' revenue growth
is due to both strategic acquisitions and growth in existing product lines. The
significant growth in segment operating profit was due to acquisitions,
operational improvement initiatives, aggressive cost containment and a general
shift toward higher margin products.

     Recent strategic acquisitions of Performance Chemicals include the purchase
of the Lytron(R) polystyrene latex plastic pigment business in 1996, which
broadened offerings to the paper industry; the acquisition of The Goodyear Tire
& Rubber Company's Calhoun, Georgia latex facility in 1998, which provided new
manufacturing capacity, increased presence in the Southeastern U.S. and an
expanded customer base; and the acquisition of Sequa Chemical's U.S. specialty
chemicals business in 1998, which expanded existing emulsion polymer market
positions and provided entry into new related specialty chemical markets. In
fiscal 1999, Performance Chemicals acquired PolymerLatex's U.S. acrylics
business in Fitchburg, Massachusetts which strengthened and diversified markets
in acrylic emulsions and other specialty chemicals; and Morton International's
global latex floor care business, which provided a complementary product line
and customer base. In 1996, Performance Chemicals sold its structural urethane
adhesives business.

     Recent strategic acquisitions of Decorative & Building Products include the
purchase of Printworld in 1997, which added paper laminates to its vinyl
laminate portfolio and provided entry into the transfer printing market for
furnishings and apparel; and the 1998 acquisition of Walker Greenbank's
U.K.-based commercial wall-covering business which provided two European
facilities and a platform from which to market other decorative and building
products. Also during 1998, Decorative & Building Products sold its residential
wallcovering business.

     The combined financial statements of Omnova Solutions generally reflect the
financial position, results of operations and cash flows of the operations
expected to be transferred to Omnova Solutions in connection with the
Distribution. Accordingly, Omnova Solutions' combined financial statements have
been carved out from the consolidated financial statements of GenCorp using the
historical results of operations and historical basis of the assets and
liabilities of Omnova Solutions' businesses and the allocation methodology
described in Note A to Omnova Solutions' Combined Financial Statements. Omnova
Solutions will operate as two business segments, Performance Chemicals and
Decorative & Building Products. The combined financial statements of Omnova
Solutions do not include certain assets and liabilities which will be
transferred to Omnova Solutions in
                                       10
<PAGE>   11

connection with the Distribution. See "Item 13. Financial Statements and
Supplementary Data -- Omnova Solutions Unaudited Pro Forma Condensed Combined
Financial Statements" and Note A to Omnova Solutions' Combined Financial
Statements. Management believes the assumptions underlying Omnova Solutions'
financial statements are reasonable.


RECENT DEVELOPMENTS

     Net sales for the Omnova Solutions businesses in the third quarter of 1999
increased 26% to $202.9 million compared to $160.7 million in the third quarter
of 1998. Sales increased in both Decorative & Building Products and Performance
Chemicals, primarily from sales attributable to acquisitions. Total segment
operating profit declined to $21.6 million for the third quarter of 1999 versus
$22.5 million in the third quarter of 1998. Operating margins decreased to 10.6%
in the third quarter of 1999 compared to 14.0% in the third quarter of 1998, due
to product mix in Decorative & Building Products, lower average unit selling
prices across certain Performance Chemicals product lines, higher raw material
prices and increased new product development spending.

     Net sales for Performance Chemicals increased for the third quarter of 1999
by 39% to $83.3 million compared to $59.9 million in the third quarter of 1998.
The increase reflects sales attributable to the 1998 acquisitions. Excluding the
effect of acquired businesses, volume was flat compared to 1998 while pricing
was down slightly. Segment operating profit during the third quarter of 1999 was
$8.7 million versus $9.6 million in the third quarter of 1998. Segment operating
margins declined to 10.4% in the third quarter of 1999 versus 16.0% in the 1998
third quarter. The decline is primarily due to lower pricing, customer deferral
of planned volume increases of styrene butadiene latex for the residential
carpet industry, and integration costs related to acquisition activity in the
latter half of 1998.

     During the third quarter of 1999, Performance Chemicals announced that it
had completed a strategic alliance agreement with Germany-based PolymerLatex (a
joint venture between Bayer AG and Degussa-Huls AG) to serve the needs of Omnova
Solutions' global paper customers. The relationship developed from the
acquisition of PolymerLatex's U.S. emulsion polymers business last December.

     Net sales for Decorative & Building Products increased for the third
quarter of 1999 by 19% to $119.6 million compared to $100.8 million in the third
quarter of 1998. The increase was mainly related to the European wallcovering
acquisition, paper laminates and building systems businesses. Segment operating
profit during the third quarter of 1999 was $12.9 million, consistent with the
third quarter of 1998. Segment operating margins declined to 10.8% in the third
quarter of 1999 from 12.8% for the third quarter of 1998, due primarily to
increased spending on new product development, higher expenses associated with
the conversion of manufacturing processes to comply with new clean air
standards, and lower commercial wallcovering volumes resulting from continuing
market softness in the U.S. and the U.K., which could continue into the
foreseeable future.

     During the third quarter of 1999, the Decorative & Building Products
business unit announced the formation of a joint venture company with
Thailand-based conglomerate Charoen Pokphand Group. The new company, CPPC
Decorative Products Co., Ltd., will serve the decorative PVC film and fabric
markets in the Asia-Pacific region and provide expanded product lines to North
America and Europe.


RESULTS OF OPERATIONS FIRST SIX MONTHS FISCAL 1999 COMPARED TO FISCAL 1998

     Net sales for the Omnova Solutions businesses in the first six months of
1999 increased 28% to $367 million compared to $287 million in the first six
months of 1998. Sales increased in both Decorative & Building Products and
Performance Chemicals, primarily from sales attributable to acquisitions. Total
segment operating profit increased 8% to $40 million for the first six months of
1999 versus $37 million in the first six months of 1998 excluding an unusual
item. Operating margins decreased to 10.9% in the first six months of 1999
compared to 12.9% in the first six months of 1998, due primarily to lower
average unit selling prices across certain Performance Chemicals product lines,
and increased new product development spending.

     Net sales for Performance Chemicals increased for the first six months of
1999 by 54% to $156 million compared to $101 million in the first six months of
1998. The increase reflects sales attributable to the 1998 acquisitions.
Excluding the effect of acquired businesses, volume was flat compared to 1998
while pricing was

                                       11
<PAGE>   12

down slightly. Segment operating profit of $14 million for the first six months
of 1999 was even with the first six months of 1998. Segment operating margins
declined to 9.0% in the first six months of 1999 versus 13.9% in the first six
months of 1998. The decline is primarily due to lower pricing and integration
costs related to acquisition activity in the latter half of 1998.

     During the first six months of 1999, Performance Chemicals completed the $8
million acquisition of Morton International's global latex floor care business,
adding a complementary product line and customer base, and expanding its
presence in Europe and the Far East. Performance Chemicals also acquired during
the first half of 1999 the U.S. acrylic emulsion polymers business of
PolymerLatex for $9 million, located in Fitchburg, Massachusetts which
strengthened and diversified markets in acrylic emulsions and other specialty
chemicals.

     Net sales for Decorative & Building Products increased for the first six
months of 1999 by 13.0% to $211 million compared to $186 million in the first
six months of 1998. The increase was mainly related to the European wallcovering
acquisition, paper laminates and building systems businesses. Segment operating
profit during the first six months of 1999 improved 13% to $26 million versus
$23 million in the first six months of 1998 excluding an unusual item. Segment
operating margins were comparable at 12.3% for the first six months of 1999
versus 12.4% for the first six months of 1998.

     During fiscal 1998, Decorative & Building Products recorded a pre-tax
unusual expense of $8 million in the second quarter, which reduced segment
operating profit, related to exiting its residential wallcovering business. This
unusual expense was subsequently adjusted to $3 million in the fourth quarter.

     Interest expense allocated from GenCorp increased to $10 million in the
first six months of 1999 compared to $3 million in the first six months of 1998.
The increase in interest expense relates to the increase in GenCorp's debt from
May 31, 1998 to May 31, 1999 due primarily to the fiscal 1998 acquisitions.

RESULTS OF OPERATIONS FISCAL 1998 COMPARED TO FISCAL 1997

     Total sales for Omnova Solutions increased $76 million, or 14%, to $624
million in 1998 from $548 million in 1997. Total segment operating profit,
excluding unusual items, in 1998 increased $20 million, or 30% to $86 million in
1998 from $66 million in 1997. Net income was $42 million in 1998 compared to
$34 million in 1997, a 24% increase.

     Sales for Performance Chemicals increased $46 million, or 26%, to $226
million in 1998 from $180 million in 1997. The increase was attributable to the
recent acquisitions and volume growth in the existing product lines, partially
offset by a modest decline in pricing. Segment operating profit for Performance
Chemicals increased by $13 million, or 59%, to $35 million in 1998 from $22
million in 1997. The increase was also attributable to the recent acquisitions
and volume growth in the existing product lines. Operating profit margins for
Performance Chemicals increased to 15.5% in 1998 from 12.2% in 1997, resulting
primarily from lower raw material pricing in 1998.

     Decorative & Building Products sales increased $30 million, or 8%, to $398
million in 1998 from $368 million in 1997. The increase was primarily
attributable to sales related to the commercial wallcovering business acquired
in 1998 and higher sales in the building systems, decorative laminates and
coated fabrics businesses. Segment operating profit, excluding unusual items,
increased by $7 million, or 16%, to $51 million in 1998 from $44 million in
1997. Segment operating profit margins for this segment increased to 12.8% in
1998 from 12.0% in 1997. These increases were related to the 1998 acquisition
and the strong performance of building systems, decorative laminates, heat
transfer and coated fabrics product lines.

     Interest expense allocated from GenCorp increased to $8 million in 1998
compared to $4 million in 1997. The increase in interest expense relates to the
increase in GenCorp's debt during fiscal 1998 due primarily to the fiscal 1998
acquisitions.

     As compared to 1998, other (income) expense was favorably impacted in
fiscal 1997 by the reimbursement of expenses related to an environmental
settlement. Omnova Solutions recognized unusual expense of $3 million in 1998
related to exiting the residential wallcovering business.

                                       12
<PAGE>   13

RESULTS OF OPERATIONS FISCAL 1997 COMPARED TO FISCAL 1996

     Total sales for Omnova Solutions increased $42 million, or 8% in 1997 to
$548 million from $506 million in 1996. Total segment operating profit,
excluding unusual items, in 1997 decreased $4 million or 6% to $66 million in
1997 from $70 million in 1996. Net income was $34 million in 1997 compared to
$37 million in 1996, an 8% decrease.

     Sales for Performance Chemicals increased 8% to $180 million in 1997 from
$166 million in 1996. The improvement was primarily due to volume increases
across paper coating and Lytron(R) product lines. Segment operating profit,
excluding unusual items, in 1997 was $22 million compared to $25 million in
1996. Segment operating profit margins declined to 12.2% from 15.1%. The
decrease was attributable to lower average selling prices and increased raw
material costs, which were consistent with the industry.

     Decorative & Building Products sales increased 8% to $368 million in 1997
from $340 million in 1996. The improvement was primarily due to volume growth in
the commercial wallcovering and roofing product lines, and the acquisition of
Technographics Inc.'s Printworld business. This increase was partially offset by
sales declines in the residential wallcovering and plastic films businesses.
Segment operating profit in 1997 was $44 million compared to $45 million in
1996. Segment operating profit margins were 12.0% in 1997 compared to 13.2% in
1996. The decrease was attributable to increased raw material costs and start-up
costs related to new product offerings during fiscal 1997.

     Interest expense allocated from GenCorp decreased to $4 million in 1997
compared to $8 million in 1996. The decrease in interest expense relates
primarily to the conversion of GenCorp's $115,000,000 8% Convertible
Subordinated Debentures Due August 1, 2002 into GenCorp common stock.

     Other (income) expense was favorably impacted in fiscal 1997 by the
reimbursement of expenses related to an environmental settlement. There were no
unusual items in 1997 as compared to 1996 when Omnova Solutions recognized
unusual income of $4 million from the sale of the structural urethane adhesives
business.

FINANCIAL RESOURCES AND CAPITAL SPENDING

  First Six Months 1999 and 1998

     Cash flow provided by operating activities for the first six months of
fiscal 1999 was $13 million as compared to $12 million in the first six months
of 1998.

     For the first six months of 1999, $16 million was used for investing
activities, including the acquisitions of the global latex floor care business
of Morton International Inc. for $8 million and the U.S. acrylics emulsion
business of PolymerLatex for $9 million, consisting of cash of $3 million and a
note for $6 million, and capital expenditures of $14 million, offset by proceeds
of $9 million from the sale of the residential wallcovering business. This is
compared to $80 million used for investing activities in the first six months of
1998, including the acquisition of The Goodyear Tire & Rubber Company's Calhoun,
Georgia latex facility for $74 million and capital expenditures of $6 million.

  Fiscal 1998, 1997, and 1996

     Cash flow provided by operating activities for fiscal 1998 was $52 million
compared to $57 million in 1997 and $51 million in 1996. Working capital
requirements for Omnova Solutions have remained relatively constant from
year-to-year.

     In fiscal 1998, $312 million was used for investing activities including
$294 million for acquisitions and capital expenditures of $18 million. The
acquisitions included Sequa Corporation's specialty chemicals unit for $108
million, Walker Greenbank's commercial wallcovering business for $112 million
and The Goodyear Tire & Rubber Company's Calhoun, Georgia latex facility for $74
million. This is compared to $58 million used for investing activities in fiscal
1997, which included the acquisition of Technographics, Inc.'s Printworld
business for $47 million and capital expenditures of $11 million. Cash flow used
in investing activities during fiscal 1996 was $15 million, which included the
acquisition of Morton International's Lytron(R) business for $4 million and

                                       13
<PAGE>   14

capital expenditures of $15 million, offset by $4 million of proceeds received
from the sale of the structural urethane adhesives business.

     Cash flow provided by financing activities in fiscal 1998 was $264 million
compared to $1 million in 1997 and cash flow used of $36 million in 1996. The
increase in net transactions with GenCorp during fiscal 1998 was primarily due
to cash required by Omnova Solutions for its fiscal 1998 acquisitions.

  Capital Spending

     Capital expenditures were made and are planned principally for capacity
expansion and asset replacement, cost reduction, safety and productivity
improvements and environmental protection. Capital expenditures totaled $14
million for the first six months of fiscal 1999, and $18 million in 1998, $11
million in 1997 and $15 million in 1996. Omnova Solutions' total capital
expenditures in 1999 are currently projected to be approximately $53 million.
Planned expenditures for 1999 increased significantly due to $10 million of
planned equipment upgrades and additions in Decorative & Building Products; $8
million planned for Performance Chemicals' capacity expansion and renovation of
its pilot plant; and $12 million for planned improvements to recently acquired
businesses including Sequa Chemicals and Walker Greenbank's commercial
wallcovering business. Management of Omnova Solutions plans to fund
substantially all of its capital expenditures from cash flow from operations. If
necessary, a portion of capital expenditures will be funded through borrowings
under its new credit facility.


     In August 1999, Omnova Solutions pre-closed a new five-year unsecured $300
million revolving credit facility which will become effective on October 1, 1999
or upon the occurrence of the Distribution. Omnova Solutions will pay a variable
commitment fee, which is currently .15 of one percent, on the unused balance.
Interest rates will be variable, primarily based on LIBOR and when drawn will be
at an average rate of 7 percent. The facility contains various debt, dividend
and investment restrictions and provisions requiring maintenance of an earnings
before interest, taxes, depreciation and amortization to interest coverage
(EBITDA/Interest Expense) ratio of 3.50 to 1.00 and debt to earnings before
interest, taxes, depreciation and amortization (Debt/EBITDA) ratio of 3.25 to
1.00. The facility will be utilized to fund a dividend to GenCorp at the time of
the special dividend contemplated by the Distribution and will also be available
for future working capital, capital expenditures and acquisition needs.


     Based upon current and anticipated levels of operations and plans for
integrating recent acquisitions, Omnova Solutions believes that its cash flow
from operations, combined with borrowings that will be available under its new
credit facility will be sufficient to enable Omnova Solutions to meet its
current and anticipated cash operating requirements, including scheduled
interest and principal payments, capital expenditures and working capital needs
for the next 12 months. However, actual capital requirements may change,
particularly as a result of any acquisitions which Omnova Solutions may make.
The ability of Omnova Solutions to meet its current and anticipated operating
requirements will be dependent upon the future performance of Omnova Solutions
which, in turn, will be subject to general economic conditions and to financial,
business and other factors, including factors beyond Omnova Solutions' control.
Depending on the nature, size and timing of future acquisitions, Omnova
Solutions may be required to raise additional financing. There can be no
assurances that additional financing will be available to Omnova Solutions on
acceptable terms. In addition, the tax rules related to the Distribution may
limit Omnova Solutions' ability for a period of time to fund acquisitions
through the issuance of equity securities. See "Item 7. Certain Relationships
and Related Transactions -- Distribution Agreement." Substantially all of the
debt of Omnova Solutions will bear interest at variable rates; therefore, its
liquidity and financial condition is and will continue to be affected by changes
in prevailing interest rates.

ENVIRONMENTAL MATTERS

     Omnova Solutions' policy is to conduct its businesses with due regard for
the preservation and protection of the environment. Omnova Solutions devotes
resources and management attention to environmental matters and actively manages
its ongoing processes to comply with extensive environmental laws and
regulations.

     Capital expenditures for projects related to the environment were
approximately $1 million in each of 1998, 1997 and 1996. Omnova Solutions
currently forecasts that capital expenditures for environmental projects will
                                       14
<PAGE>   15

approximate $2 million in each of 1999 and 2000. During 1998, noncapital
expenditures for environmental compliance and protection totaled $4 million all
of which were for recurring costs associated with managing hazardous substances
and pollution abatement in ongoing operations. Similar noncapital expenditures
were $3 million in each of 1997 and 1996. It is presently expected that
noncapital environmental expenditures for the next several years will be
consistent with historical expenditure levels.

     Management believes, on the basis of presently available information, that
resolution of environmental matters will not materially affect future results of
operations, liquidity, capital resources or the consolidated financial condition
of Omnova Solutions.

INFORMATION SYSTEMS AND THE YEAR 2000

     Omnova Solutions is currently engaged in a comprehensive project to upgrade
its information, technology, manufacturing and facilities computer hardware and
software programs to address the Year 2000 issue at its domestic and
international businesses. The scope of this project encompasses acquisitions
made by Omnova Solutions to address any Year 2000 issues arising from those
acquisitions. Many of Omnova Solutions' systems include new hardware and updated
software packages purchased from established vendors who have represented that
these systems are Year 2000 ready. Omnova Solutions does not have large
centralized systems, a factor which Omnova Solutions believes reduces the risk
of a single point of failure having wide-spread impact on Omnova Solutions.

     As part of this project, Omnova Solutions has formally communicated with
all of its significant suppliers, vendors and large customers to determine the
extent to which Omnova Solutions is vulnerable to those parties' failures to
correct their own Year 2000 issues. As of May 31, 1999, Omnova Solutions has
received approximately 95% of the responses, and those responses generally
indicate that these parties will be Year 2000 ready. All third parties with whom
Omnova Solutions has a material relationship have indicated that they will be
Year 2000 compliant.

     Omnova Solutions has completed an inventory and assessment of its
information technology systems. Both internal and external resources are being
utilized to test Omnova Solutions' software for Year 2000 readiness and, where
necessary, the systems are being remediated through upgrading, replacement or
reprogramming. Also, Omnova Solutions has completed an inventory and assessment
of its non-information technology (embedded) systems, prioritizing the impact of
each of these systems on Omnova Solutions' ability to conduct its operations
and, as necessary, obtaining vendor verification and/or remediation of those
systems. The process of remediation, testing and implementation will be an
iterative process until all critical systems are Year 2000 ready. However, as of
July 31, 1999, Omnova Solutions believes that the remediation stage, which
involves changing or upgrading systems, was approximately 90% complete. In
addition, as of the same date, the testing stage was approximately 85% complete
and the implementation stage, which involves placement of systems in a
production environment, was approximately 82% complete.

     The estimated cost for this project is projected to range between $4
million and $5 million, which is being funded through operating cash flows.
Omnova Solutions has spent approximately $3 million as of May 31, 1999 on this
project, most of which has been for internal remediation efforts and expects to
spend a significant amount of the remaining budget by the end of the third
quarter of fiscal 1999.

     Based upon currently available information and considering Omnova
Solutions' decentralized systems and Year 2000 efforts, management believes that
the most reasonably likely worst case scenario could result in minor short-term
business interruptions. Omnova Solutions is preparing contingency plans which
include alternative sourcing to minimize any disruptions to its businesses
resulting from a vendor or supplier not being Year 2000 ready. However, failure
by Omnova Solutions and/or vendors and customers to complete Year 2000 readiness
work in a timely manner could have a material adverse effect on certain of
Omnova Solutions' operations. Omnova Solutions' exposure could increase or its
timetable for Year 2000 readiness could be delayed as a result of any new
acquisitions.

<PAGE>   16

ADOPTION OF THE EURO

     Based upon a preliminary evaluation, management believes that the adoption
of the Euro by the European Economic Community will not have a material impact
on Omnova Solutions' international businesses. Omnova Solutions' foreign
operations currently are small and each operation conducts the majority of its
business in a single currency with minimal price variations between countries.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

     Although Omnova Solutions conducts business in foreign countries,
international operations were not material to Omnova Solutions' consolidated
financial position, results of operations or cash flows as of May 31, 1999.
Additionally, foreign currency transaction gains and losses were not material to
Omnova Solutions' results of operations for the six months ended May 31, 1999.
While international operations have not been significant in the past, Omnova
Solutions could be subject to material foreign currency exchange rate risk with
respect to future operations and cash flows due to Omnova Solutions' acquisition
of the European wallcovering business in late 1998. To date, Omnova Solutions
has not entered into any significant foreign currency forward exchange contracts
or other derivative financial instruments to hedge the effects of adverse
fluctuations in foreign currency exchange rates. Omnova Solutions is evaluating
the future use of these financial instruments.

NEW ACCOUNTING PRONOUNCEMENTS

     Omnova Solutions adopted Statement of Financial Accounting Standards No.
130, "Reporting Comprehensive Income" (SFAS 130), as of December 1, 1998, which
established standards for reporting and displaying comprehensive income and its
components in the financial statements. The adoption of SFAS 130, which had no
impact on Omnova Solutions' net income or divisional equity, requires
translation adjustments to be included in other comprehensive income.

     In June 1997, the Financial Accounting Standards Board (FASB) issued
Statement No. 131, "Disclosures about Segments of an Enterprise and Related
Information" (SFAS 131). This statement is required to be adopted in fiscal year
1999. SFAS 131 requires that annual and interim financial and descriptive
information about reportable operating segments be reported on the same basis
used internally for evaluating segment performance and the allocation of
resources. While Omnova Solutions has not yet determined the impact of adopting
SFAS 131 on its financial statement disclosures, Omnova Solutions does not
expect any change to its primary financial statements.

     In June 1998, the FASB issued Statement No. 133, "Accounting for Derivative
Instruments and Hedging Activities", which is required to be adopted in fiscal
year 2001. Because of Omnova Solutions' minimal use of derivatives, management
does not anticipate that the adoption of this Statement will have a significant
effect on earnings or the financial position of Omnova Solutions.

     In April 1998, the American Institute of Certified Public Accountants
(AICPA) issued Statement of Position (SOP) 98-5, "Reporting the Costs of
Start-up Activities" (SOP 98-5). SOP 98-5 is effective for Omnova Solutions
beginning on December 1, 1999, and requires that start-up costs capitalized
prior to December 1, 1999 be written off and any future start-up costs be
expensed as incurred. Omnova Solutions has no capitalized start-up costs;
therefore the adoption of SOP 98-5 will not have an effect on the combined
financial statements.

     In March 1998, the AICPA issued SOP 98-1, "Accounting For the Costs of
Computer Software Developed For or Obtained For Internal Use" (SOP 98-1). SOP
98-1 is effective for Omnova Solutions beginning on December 1, 1999. SOP 98-1
will require the capitalization of certain costs incurred after the date of
adoption in connection with developing or obtaining software for internal use.
Omnova Solutions believes it is in compliance with the standards established by
SOP 98-1 and that its implementation will not impact Omnova Solutions' future
earnings or financial position.

FORWARD-LOOKING STATEMENTS

     This Form 10 contains forward-looking statements as defined by the Private
Securities Litigation Reform Act of 1995. These statements present (without
limitation) the expectations, beliefs, plans and objectives of

                                       16
<PAGE>   17

management and future financial performance and/or assumptions underlying or
judgments concerning matters discussed in this document. These discussions and
any other discussions contained in this registration statement, except to the
extent that they contain historical facts, are forward-looking and accordingly
involve estimates, assumptions, judgments and uncertainties; in particular, this
pertains to management's comments on financial resources, capital spending and
the outlook for each of Omnova Solutions' business segments. The outcomes of
forward-looking statements and material contingencies could differ materially
from those discussed due to inherent economic risks and changes in prevailing
governmental policies and regulatory actions. In addition to certain contingency
matters and their respective cautionary statements discussed elsewhere in this
Form 10, the Forward-Looking Statements section of this Management's Discussion
and Analysis indicates some important factors that could cause actual results or
outcomes to differ materially from those addressed in the forward-looking
statements.

     Some important factors that could cause Omnova Solutions' actual results or
outcomes to differ from those expressed in its forward-looking statements
include, but are not limited to, the following:

     - General economic trends affecting Omnova Solutions' markets

     - Governmental and regulatory policies including environmental regulations

     - Omnova Solutions' acquisition activities

     - Raw material prices for chemical feed stocks including polyvinyl
       chloride, styrene and butadiene

     - The ability of Omnova Solutions and its customers and vendors to
       successfully modify and convert their systems to be Year 2000 ready

     - Fluctuations in exchange rates of foreign currencies and other risks
       associated with foreign operations

     Additional risk factors may be described from time to time in Omnova
Solutions' filings with the Securities and Exchange Commission. All of these
risk factors are difficult to predict, contain material uncertainties that may
affect actual results and may be beyond Omnova Solutions' control.

Board will be set at nine, and there will be three vacancies on the Omnova
Solutions Board following the Distribution. The Omnova Solutions Board may fill
one or more of those vacancies and those persons will serve until the annual
meeting of Omnova Solutions shareholders to be held in 2000, 2001 or 2002.
GenCorp is currently evaluating additional candidates to serve as additional
directors of Omnova Solutions following the Distribution.

CLASSIFICATION OF OMNOVA SOLUTIONS BOARD

Solutions Board will be divided into three classes of directors to be as nearly
equal in number of directors as possible. Class I will consist of John B.

Omnova Solutions' 2000 annual meeting of shareholders. Class II will consist of
Diane E. McGarry and Steven W. Percy and their current term of office will

each annual shareholders' meeting, directors will be elected for a term of three
years and hold office until their successors are elected and qualified or until
their earlier removal or resignation. Newly created directorships resulting from
an increase in the number of directors or any vacancies on Omnova Solutions'
Board resulting from death, resignation, disqualification, removal or other
cause may be filled by a majority of the remaining directors then in office.

COMMITTEES

     The Omnova Solutions Board is expected to have five standing committees:
(1) Organization & Compensation; (2) Audit; (3) Executive; (4) Finance; and (5)
Nominating & Corporate Governance.

     ORGANIZATION & COMPENSATION COMMITTEE. The Organization & Compensation

effectiveness and performance of senior management and make recommendations to
the Omnova Solutions Board concerning the appointment and removal of officers.
It will also periodically review the compensation philosophy, policies and
practices of Omnova Solutions and make recommendations to the Omnova Solutions
Board concerning major changes, as appropriate. It will annually review changes
in Omnova Solutions' employee benefit, savings and retirement plans and report

administer Omnova Solutions' incentive and deferred compensation plans and
approve, and in some cases recommend to the Omnova Solutions Board for approval,
the compensation of employee-directors, officers, and principal executives of
Omnova Solutions. The members of the Organization & Compensation Committee are
expected to be Charles A. Corry, Chairman, Edward P. Campbell, Diane E. McGarry
and Steven W. Percy.

the audits to be performed, the adequacy of services performed by, and the fees

ethical conduct. Members of the Audit Committee are expected to be: Steven W.
Percy, Chairman, Edward P. Campbell and Diane E. McGarry.

     EXECUTIVE COMMITTEE. During the intervals between meetings of the Board of
Directors, the Executive Committee, unless restricted by resolution of the
Omnova Solutions Board, will be able to exercise, under the control and
direction of the Omnova Solutions Board, all of the powers of the Omnova
Solutions Board in the management and control of the business of Omnova
Solutions. Members of the Executive Committee are expected to be: John B.
Yasinsky, Chairman, Charles A. Corry and R. Byron Pipes.

     FINANCE COMMITTEE. The Finance Committee will make recommendations to the

Solutions' employee benefit funds and make recommendations to the Omnova

directors, the composition of the Omnova Solutions Board, structure and function
of Omnova Solutions Board committees, retirement policies and compensation and
benefits of directors. It will recommend to the Omnova Solutions Board qualified
candidates to serve as directors of Omnova Solutions and aid in attracting

submitted by shareholders. Members of the Nominating & Corporate Governance
Committee are expected to be: R. Byron Pipes, Chairman, Charles A. Corry and

ITEM 6. EXECUTIVE COMPENSATION.

COMPENSATION OF DIRECTORS

     Each nonemployee director of Omnova Solutions will receive a retainer of
$24,000 per year and an attendance fee of $1,000 for each Board and Committee
meeting attended. Nonemployee directors who served as Chairman of a committee of
the Omnova Solutions Board will receive an annual fee of $2,000 in consideration
of that service.

     Nonemployee directors will be able to elect annually to defer all or a
percentage of their retainer, any committee Chairman's fee and meeting
attendance fees pursuant to a deferred compensation plan for nonemployee
directors. The plan will be unfunded, and deferred amounts will be credited, at
the election of the director, with phantom shares in an Omnova Solutions stock
fund, an S&P 500 index fund, or a cash deposit program. Deferred amounts and
earnings will be payable after termination of Omnova Solutions Board service in
either a lump sum or installments as elected by the director.

     In March 1998 each GenCorp nonemployee director received 200 restricted
shares of GenCorp common stock. These restricted shares will vest March 25,
2000. In March 1999, each GenCorp nonemployee director received 250 restricted
shares of GenCorp common stock. These restricted shares will vest on March 30,
2001. Vesting will be accelerated in full upon resignation from the GenCorp
Board to serve on the Omnova Solutions Board. Dividends on restricted shares are
automatically reinvested through GenCorp's dividend reinvestment program unless
a director chooses otherwise. All shares may be voted, but ownership may not be
transferred until

                                       23
<PAGE>   24

service on the GenCorp Board terminates. Unvested shares will be forfeited in
the event of a voluntary resignation (other than resignation to serve on the
Omnova Solutions Board) or refusal to stand for reelection, but vesting will be
accelerated in the event of death, disability or retirement pursuant to the
Retirement Plan for Nonemployee Directors described below or upon the occurrence
of a change in control or announcement of a tender or exchange offer which would
result in a person holding beneficial ownership of 30% of more of the
outstanding GenCorp common stock.

     Nonemployee directors of Omnova Solutions will be eligible for stock option
grants and restricted stock awards under the Omnova Solutions 1999 Equity and
Performance Incentive Plan.

     Each nonemployee director who terminates his or her service on the Omnova
Solutions Board after at least 60 months of service (including service on the
GenCorp Board) will receive an annual retirement benefit equal to the retainer
in effect on the date the director's service terminates, payable in monthly
installments, until the number of monthly payments made equals the lesser of (1)
the individual's months of service as a director, or (2) 120 monthly payments.
In the event of death prior to payment of the applicable number of installments,
the aggregate amount of unpaid monthly installments will be paid, in a lump sum,
to the retired director's surviving spouse or other designated beneficiary, if
any, or to the retired director's estate.

     Under the Omnova Solutions Board's retirement policy, a director's term of
office normally will expire at the annual meeting following his or her
seventieth birthday regardless of the term of the class for which the director
was last elected. Under special circumstances, however, the Omnova Solutions
Board may waive immediate compliance and request that a director postpone his or
her retirement until a later date.

     Directors who are also employees of Omnova Solutions will not be
compensated separately for serving on the Omnova Solutions Board and will not be
paid a retainer or additional compensation for attendance at Board or committee
meetings.

     The following tables set forth information concerning annual and long-term
compensation for services rendered to GenCorp for fiscal 1998, 1997 and 1996 by

(4) The potential realizable values are shown in the table in conformity with
    Securities and Exchange Commission regulations, and are not intended to
    forecast possible future appreciation. GenCorp is not aware of any formula
    which will predict with reasonable accuracy the future appreciation of
    equity securities. No benefit can be realized by optionees without an
    appreciation in stock price, which will benefit all shareholders
    commensurately.

    bonus shown in the Summary Compensation Table above. Performance awards
    under GenCorp's Long-Term Incentive Program for the three-year performance
    period ending November 30, 1999 will be determined based upon (1) actual
    performance up to the date of the special dividend contemplated by the
    Distribution, and (2) budgeted performance, for the remainder of the period,
    according to GenCorp's annual operating plan. Pro rata performance awards
    will be paid under the GenCorp plan for the performance periods ending
    November 30, 2000 and November 30, 2001. Pro rata performance awards for
    each partial performance period will be determined based upon (1) actual
    performance up to the date of the special dividend contemplated by the
    Distribution, and (2) budgeted performance, for the remainder of the fiscal
    year ending November 30, 1999, according to GenCorp's annual operating plan.

PENSION BENEFITS

     GenCorp's salaried pension plans include several formulas for the
determination of benefits, and require that the formula providing the highest
benefit be utilized to determine an individual employee's actual benefit.
Benefits for Messrs. Mass, McMullen, Zima and Hicks have been determined
pursuant to a formula which utilizes five-year average compensation for years of
service prior to December 1, 1999 and a career average formula for service from
December 1, 1999 to normal retirement. The benefit for Mr. Yasinsky has been
determined pursuant to the terms of his employment agreement. Estimated benefits
are shown below because the required calculations do not lend themselves to a
typical pension plan table where benefits can be determined by the reader solely
upon the basis of years of service and final compensation.

(1) Retirement benefits shown in the table for Messrs. Mass, McMullen, Zima and
    Hicks were calculated pursuant to the terms of the Pension Plan for Salaried
    Employees of GenCorp Inc. (the "GenCorp Pension Plan"). There is no offset
    for Social Security payments. Mr. Yasinsky's retirement benefit has been
    determined pursuant to the supplemental pension provisions of his employment
    agreement described under " -- Employment Contracts and Termination of
    Employment and Change in Control Arrangements."

    The benefits shown are estimated and have not been adjusted for any survivor
    option. Each estimated benefit is based upon the assumption that the
    executive will remain an employee until age 65 at a rate of compensation
    equivalent to that in effect on December 1, 1998 and that the pension plan
    under which the estimated benefit is calculated will remain unchanged.

    Benefits for Messrs. Mass, McMullen, Zima and Hicks have been determined by
    a formula which provides for a benefit (A) for years of service prior to
    December 1, 1999 of (1) 1.125% of five-year average compensation ("average
    compensation") up to the average Social Security wage base ("ASSWB") plus
    1.5% of average compensation in excess of the ASSWB multiplied by the total
    of such years of service up to 35 years and (2) 1.5% of average compensation
    multiplied by the total years of service in excess of 35 years, and (B) for
    each year of service after December 1, 1999 (1) prior to attainment of 35
    years of service, 1.625% of annual compensation up to the ASSWB plus 2.0% of
    annual compensation in excess of the ASSWB, and (2) after attainment of 35
    years of service, 2.0% of annual compensation.

    The benefits shown in the table have not been reduced to reflect either (1)
    the limitation on includable compensation or the overall benefit limitation
    imposed on pension plans qualified under Section 401(a) of the Code, or (2)
    a plan's own exclusions from includable compensation, since the amount of
    any of those reductions will be restored to the individual pursuant to the
    terms of GenCorp's Benefits Restoration Plan, a nonfunded plan with benefits
    payable out of the general assets of GenCorp.

(2) Mr. Yasinsky's benefit is the product of (1) total years of service
    (including 30 years credited upon Mr. Yasinsky's employment with GenCorp,
    plus additional years accrued as an employee with Omnova Solutions until age
    65), (2) 1.47%, and (3) the average of his five highest years of
    compensation (salary and incentive bonus only) during the ten years
    preceding retirement. Under the terms of Mr. Yasinsky's employment
    agreement, amounts determined pursuant to the foregoing formula will be paid
    out of GenCorp funds and will be offset by any payments made from the
    GenCorp Pension Plan and the pension plan of his prior employer.

OMNOVA SOLUTIONS 1999 EQUITY AND PERFORMANCE INCENTIVE PLAN

     Omnova Solutions desires to establish an equity performance and incentive
plan in order to integrate GenCorp's existing stock option and long-term
incentive plans and to more closely align the interests of its executives with
those of Omnova Solutions' shareholders. For this purpose, subject to the
approval of the shareholders, Omnova Solutions has adopted the Omnova Solutions
1999 Equity and Performance Incentive Plan. A copy of the plan has been filed as
an exhibit to this Form 10. A summary of the plan is set forth below.

     Approximately 8 officers, 50 key employees and 8 nonemployee directors of
Omnova Solutions are expected to be eligible to receive awards under the plan.

                                       28

  PLAN SUMMARY

     General. Under the plan, Omnova Solutions' Board is authorized to make
awards of (1) options to purchase shares of Omnova Solutions' common stock, (2)
performance stock and performance units, (3) restricted stock, (4) deferred
stock or (5) appreciation rights. Omnova Solutions' Organization and
Compensation Committee will be authorized to oversee the plan and to make awards
and grants under the plan.

     Shares Available Under the Plan. The number of shares of Omnova Solutions'
common stock that may be issued or transferred (1) upon the exercise of options
("Option Rights"), (2) as restricted stock ("Restricted Stock") and released
from all substantial risks of forfeiture, (3) as deferred stock ("Deferred
Stock"), (4) in payment of performance stock ("Performance Stock") or
performance units ("Performance Units") that have been earned, (5) in payment of
dividend equivalents paid with respect to awards made under the plan, or (6) in
payment of appreciation rights may not exceed a total of 2,400,000, subject to
some adjustments pursuant to the terms of the plan. These shares of common stock
may be original issue or treasury shares or a combination of both.

     Eligibility. Officers, key employees and nonemployee directors of Omnova
Solutions, as well as any person who has agreed to begin serving in such
capacity within 30 days of the date of the grant are eligible to be selected by
Omnova Solutions' Board to receive benefits under the plan. Omnova Solutions'
Organization and Compensation Committee will select those who will receive
grants on the basis of management objectives.

     Option Rights. Option Rights entitle the optionee to purchase shares of
Omnova Solutions' common stock at a predetermined price per share (which may not
be less than the market value at the date of grant, except for non-qualified
stock options granted in lieu of salary or bonus, which may be not less than 85%
of the market value at the date of grant). Each grant will specify whether the
option price will be payable (1) in cash at the time of exercise, (2) by the
transfer to Omnova Solutions of shares of common stock owned by the optionee for
at least six months, having a value at the time of exercise equal to the option
price, (3) if authorized by Omnova Solutions' Board or its Organization and
Compensation Committee, the delivery of shares of Restricted Stock or other
forfeitable shares, Deferred Stock, Performance Stock, other vested Option
Rights, or Performance Units, or (4) a combination of those payment methods.
Grants may provide for deferred payment of the option price from the proceeds of
sale through a broker on the date of exercise of some or all of the shares of
Omnova Solutions' common stock to which the exercise relates.

     No Option Rights may be exercisable more than ten years from the date of
grant. Each grant must specify the period of continuous employment with Omnova
Solutions that is required before the Option Rights become exercisable. Grants
may provide for earlier exercise of an Option Right in the event of a "change in
control" of Omnova Solutions or other similar transactions or events. Grants may
also specify management objectives that must be achieved as a condition to the
exercise of the option. Successive grants may be made to the same optionee
whether or not previously granted Option Rights remain unexercised.

     Restricted Stock. An award of Restricted Stock involves the immediate
transfer of ownership of a specific number of shares of Omnova Solutions common
stock by Omnova Solutions to a participant in consideration of the performance
of services. The participant is immediately entitled to voting, dividend and
other ownership rights in such shares. The transfer may be made without
additional consideration or in consideration of a payment by the participant
that is less than current market value, as the Omnova Solutions Board may
determine. The Omnova Solutions Board may condition the award on the achievement
of specified management objectives.

     Restricted Stock must be subject to a "substantial risk of forfeiture"
within the meaning of Section 83 of the Internal Revenue Code for a period to be
determined by the Omnova Solutions Board. An example would be a provision that
the Restricted Stock would be forfeited if the participant ceased to serve as an
officer or key employee of Omnova Solutions during a specified period of years.
If service alone is the criterion for non-forfeiture, the period of service must
be at least three years; if other management objectives are included, non-
forfeiture may occur one year from the date of grant. In order to enforce these
forfeiture provisions, the transferability of Restricted Stock will be
prohibited or restricted in a manner and to the extent prescribed by Omnova
Solutions' Board for the period during which the forfeiture provisions are to
continue. Omnova

                                       29
<PAGE>   30

Solutions' Board may provide for a shorter period during which the forfeiture
provisions are to apply in the event of a change in control of Omnova Solutions
or other similar transaction or event.

     Deferred Stock. An award of Deferred Stock constitutes an agreement by
Omnova Solutions to deliver shares of its common stock to the participant in the
future in consideration of the performance of services. However, the Deferred
Stock award may be subject to the fulfillment of certain conditions, such as
management objectives, during the deferral period specified by Omnova Solutions'
Board. During the deferral period, the participant cannot transfer any rights in
the award and has no right to vote the shares of Deferred Stock, but Omnova
Solutions' Board may, on or after the date of the award, authorize the payment
of dividend equivalents on such shares on a current, deferred or contingent
basis, either in cash or in additional shares of Omnova Solutions common stock.
Awards of Deferred Stock can be made without additional consideration or in
consideration of a payment by the participant that is less than the market value
per share on the date of award. Deferred Stock must be subject to performance of
services for at least three years; provided that if management objectives are
included, the performance of services must be for at least one year. Omnova
Solutions' Board determines the deferral period at the date of the award, and
may provide for a deferral period of less than three years in the event of a
change in control of Omnova Solutions or other similar transaction or event.

     Performance Stock and Performance Units. Performance Stock and Performance
Units involve awards that become payable upon the achievement of specified
management objectives during a designated performance period. This performance
period may be subject to earlier termination in the event of death, retirement
or a change in control of Omnova Solutions or other similar transaction or
event. A minimum level of acceptable achievement may also be established by
Omnova Solutions' Board. If, by the end of the performance period, the
participant has achieved the specified management objectives, the participant
will be deemed to have fully earned the Performance Stock or Performance Units.
If the participant has not achieved the management objectives, but has attained
or exceeded the predetermined minimum, the participant will be deemed to have
partly earned the Performance Stock and/or Performance Units (such part to be
determined in accordance with a formula). To the extent earned, the Performance
Stock and/or Performance Units will be paid to the participant at the time and
in the manner determined by Omnova Solutions' Board in cash, shares of Omnova
Solutions common stock or in any combination of those methods. Each award of
Performance Stock or Performance Units may be subject to adjustment to reflect
changes in compensation or other factors, so long as no adjustment would result
in the loss of an available exemption for the award under Section 162(m) of the
Internal Revenue Code. Omnova Solutions' Board or its Organization and
Compensation Committee may provide for the payment of dividend equivalents to
the holder on a current, deferred or contingent basis, either in cash or in
additional Omnova Solutions common stock.

     Appreciation Rights. An Appreciation Right ("Appreciation Right") entitles
the holder, by surrender of the related Option Right (if granted in connection
with Option Rights) or by itself (if granted as a free-standing Appreciation
Right), to receive from Omnova Solutions an amount equal to 100%, or a lesser
percentage as Omnova Solutions' Board may determine, of the spread between the
strike price (or the option price if granted in tandem with Option Rights) and
the then-current market value of Omnova Solutions' common stock. Any grant may
specify that the amount payable on exercise of an Appreciation Right may be paid
by Omnova Solutions in cash, in Omnova Solutions common stock, or in any
combination of the two, and may either grant to the optionee or retain in Omnova
Solutions' Board the right to elect among those alternatives. Any grant may
specify that the Appreciation Right may be exercised only in the event of a
"change in control" or other similar transaction or event. Any grant of
Appreciation Rights may specify management objectives that must be achieved as a
condition to the exercise of those rights.

     Management Objectives. The plan requires that Omnova Solutions' Board
establish performance goals for purposes of Performance Stock and Performance
Units. In addition, if Omnova Solutions' Board so chooses, Option Rights,
Restricted Stock and Deferred Stock may also specify management objectives.
Management objectives may be described either in terms of firm-wide objectives,
individual participant objectives, or objectives related to performance of the
division, subsidiary, department or function within Omnova Solutions in which
the participant is employed. Management objectives applicable to any award may
include specified levels of and/or growth in (1) cash flow, (2) earnings per
share, (3) earnings before interest and taxes, (4) earnings per
                                       30
<PAGE>   31

share growth, (5) net income, (6) return on assets, (7) return on assets
employed (8) return on equity, (9) return on invested capital, (10) return on
total capital, (11) revenue growth, (12) stock price, (13) total return to
stockholders, (14) economic value added, (15) operating profit growth, or any
combination of those methods. If Omnova Solutions' Board determines that a
change in the business, operations, corporate structure or capital structure of
Omnova Solutions, or the manner in which it conducts its business, or other
events or circumstances render the management objectives unsuitable, Omnova
Solutions' Board may modify the performance goals or the related minimum
acceptable level of achievement, in whole or in part, as Omnova Solutions' Board
deems appropriate and equitable, unless the result would be to make an award
otherwise eligible for an exemption under Section 162(m) of the Internal Revenue
Code ineligible for such an exemption.

     Transferability. Except as otherwise determined by Omnova Solutions' Board,
no Option Right or other award under the plan is transferable by a participant
other than by will or the laws of descent and distribution, or (except for
incentive stock options) to the participant's immediate family or trusts
established solely for the benefit of one or more members of the immediate
family. Except as otherwise determined by Omnova Solutions' Board, Option Rights
are exercisable during the optionee's lifetime only by him or her.

     The Board of Directors may specify at the date of grant that part or all of
the shares of Omnova Solutions common stock that are (1) to be issued or
transferred by Omnova Solutions upon exercise of Option Rights, upon termination
of the deferral period applicable to Deferred Stock or upon payment under any
grant of Performance Stock or Performance Units or (2) no longer subject to the
substantial risk of forfeiture and restrictions on transfer referred to in the
plan, shall be subject to further restrictions on transfer.

     Adjustments. The Plan provides that the number of shares available for
awards will be adjusted to account for (a) shares relating to awards that expire
or are forfeited under the Plan, or (b) shares that are transferred, surrendered
or relinquished in payment of the option exercise price for satisfaction of
withholding rules for the exercise or receipt of awards under the Plan. This
permits the grant of additional awards equal to the number of shares turned in
by award recipients. The maximum number of shares of Omnova Solutions common
stock covered by outstanding Option Rights, Deferred Stock, Performance Stock
and Restricted Stock granted under the plan, and the prices per share applicable
to those shares, are subject to adjustment in the event of stock dividends,
stock splits, combinations of shares, recapitalizations, mergers,
consolidations, spin-offs, reorganizations, liquidations, issuances of rights or
warrants, and similar events. In the event of any such transaction, Omnova
Solutions' Board is given discretion to provide a substitution of alternative
consideration for any or all outstanding awards under the plan, as it in good
faith determines to be equitable under the circumstances, and may require the
surrender of all awards so replaced. Omnova Solutions' Board may also make or
provide for adjustments in the numerical limitations under the plan as Omnova
Solutions' Board may determine appropriate to reflect any of the foregoing
transactions or events.

     Omnova Solutions' Board is authorized to interpret the plan and related
agreements and other documents. Omnova Solutions' Board may make awards to
employees under any or a combination of all of the various categories of awards
that are authorized under the plan, or in its discretion, make no awards. The
plan may be amended from time to time by Omnova Solutions' Board. However, any
amendment that must be approved by the shareholders of Omnova Solutions in order
to comply with applicable law or the rules of the principal national securities
exchange or quotation system upon which Omnova Solutions common stock is traded
or quoted will not be effective unless and until such approval has been obtained
in compliance with those applicable laws or rules. These amendments would
include any increase in the number of shares issued or certain other increases
in awards available under the plan (except for increases caused by adjustments
made pursuant to the plan). Presentation of the plan or any amendment of the
plan for shareholder approval is not to be construed to limit Omnova Solutions'
authority to offer similar or dissimilar benefits through plans that are not
subject to shareholder approval.

     Omnova Solutions' Board may provide for special terms for awards to
participants who are foreign nationals or who are employed by Omnova Solutions
outside the United States of America as Omnova Solutions' Board may consider
necessary or appropriate to accommodate differences in local law, tax policy or
custom.

                                       31
<PAGE>   32

     The plan provides that awards representing no more than 3% of the shares
available under the plan may not be required to meet certain restrictions
otherwise applicable to restricted stock, deferred stock and performance stock
awards under the plans.

     Omnova Solutions' Board may not, without further approval of its
shareholders, authorize the amendment of any outstanding Option Right to reduce
the option price. Furthermore, no Option Right may be canceled and replaced with
awards having a lower option price without further approval of the shareholders
of Omnova Solutions. The plan does not confer on any participant a right to
continued employment with Omnova Solutions.

  ACCOUNTING TREATMENT

     Performance Shares and Performance Units will require a charge against
income of Omnova Solutions periodically representing increases in the value of
the anticipated benefits. The charge is based on the dollar amount expected to
be paid at the end of the performance period. Restricted Stock and Deferred
Stock will require a charge against income equal to the fair market value of the
awarded shares at the time of award less the amount, if any, paid or payable by
the awardee. The charge is spread over the earn-out period for the Restricted or
Deferred Stock. Given the variety of awards that may be made separately or in
combination under the plan, actual awards may result in periodic charges against
income in some other circumstances.

EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AND CHANGE IN CONTROL
ARRANGEMENTS

     If the Directors remove Mr. Yasinsky from the position of Chairman and CEO
of GenCorp or Omnova Solutions prior to age 65 for any reason other than for
"cause" as defined in his October 18, 1993 employment agreement, Mr. Yasinsky
may elect to terminate his employment and receive (a) a termination payment
equal to two times the sum of (1) his annual base salary at the time of
termination and (2) his incentive bonus for the last completed fiscal year
preceding termination, and (b) a supplemental pension determined as described in
footnote (2) under "Pension Benefits". The agreement also provides that Mr.
Yasinsky will participate in the GenCorp Pension Plan and that his supplemental
pension will be offset by the amount of any pension payment made from the
GenCorp Pension Plan and pension payment received from his former employer. The
normal form of payment of the supplemental pension will be a 50% or 100% joint
and survivor annuity, unless Mr. Yasinsky elects a lump-sum payment. If elected,
the amount of any lump-sum payment will be calculated using the then-current
interest rate for 30-year Treasury securities, as approved by the GenCorp Board
for the calculation of lump-sum payments under all GenCorp benefit plans and
deferred compensation arrangements. In the event of death prior to electing a
payment option, the supplemental pension will be paid to Mr. Yasinsky's
surviving spouse for her life, calculated as if he had attained age 62, retired,
and elected a joint and 100% survivor annuity. In the event of disability prior
to age 62, GenCorp or Omnova Solutions will pay Mr. Yasinsky an amount equal to
60% of his base monthly salary (offset for payments received under Social
Security) until eligible for supplemental pension benefits at age 62.

     Mr. Nathaniel J. Mass' May 13, 1996 employment agreement provided an
initial base salary of $300,000 per annum, increasing to $325,000 on February 1,
1997, a one time bonus of $150,000 to compensate him for loss of an expected
bonus payment from his prior employer, a prorated 1996 incentive bonus, with a
minimum of $75,000 and an option to purchase 75,000 shares of GenCorp common
stock at an exercise price equal to the closing market price on his employment
date. If Mr. Mass' employment is terminated by GenCorp, for reasons other than
for cause or due to disability or mandatory retirement, he will be eligible to
receive separation pay in the form of (a) continuing base salary at the rate in
effect on the date of termination and (b) continuing bonus payments, each in the
annualized amount of his last bonus payment preceding the date of termination,
for a period not to exceed the shortest of (1) two years from the date of
termination, or (2) until he obtains comparable employment.

     Mr. Kevin McMullen's July 16, 1996 employment agreement provided an initial
base salary of $250,000 per annum, subject to pro-rata adjustment at the end of
the 1996 fiscal year, a one-time hiring bonus of $95,000, a 1996 incentive bonus
of $125,000, and an option to purchase 75,000 shares of GenCorp common stock at
an exercise price equal to the closing market price on his employment date. If
Mr. McMullen's employment is terminated by GenCorp other than for cause,
disability or retirement, he will be eligible for continuation of his

                                       32
<PAGE>   33

base salary in effect at termination for a period not to exceed the shorter of
(1) eighteen months or (2) until he obtains comparable employment.

     GenCorp adopted the 1999 Key Employee Retention Plan which provides for
payment of up to two annual cash retention payments to eligible employees who
satisfactorily continue their employment with GenCorp or Omnova Solutions,
attain specific performance objectives (including completion of the
Distribution) and meet all plan requirements. In the event that the Distribution
does not occur before February 1, 2000, for whatever reason, a pro rata share of
the retention payment will be made and there will be no obligation to pay any
future payments. To date, 14 key employees have received Key Employee Retention
Letter Agreements pursuant to the plan, providing for individual total retention
payments ranging from $75,000 to $800,000. Pursuant to the plan, the following
payments may be made to the following Named Omnova Solutions Officers at the end
of the first and second years, respectively: Mr. Yasinsky, $200,000 and
$600,000; Mr. McMullen, $150,000 and $150,000; Mr. Mass, $150,000 and $150,000;
Mr. Zima, $150,000 and $150,000; and Mr. Hicks, $75,000 and $75,000.

     At the time of the Distribution, it is intended that Omnova Solutions will
assume the foregoing employment contracts and termination of employment and
change-in-control arrangements with appropriate modifications.

     During 1997 the GenCorp Board of Directors authorized GenCorp to enter into
amended and restated severance agreements with ten existing elected officers.
The severance agreements provide for a severance payment in an amount equal to
the officer's base salary plus bonus (as defined in the agreement) multiplied by
a factor of 3 in the case of the GenCorp Chief Executive Officer or a GenCorp
Senior Vice President, or by a factor of 2 for other covered officers, if within
three years after a change-in-control (as such term is defined in the
agreements), the officer's employment is terminated (1) by GenCorp for any
reason other than death, disability or cause, or (2) by the officer following
the occurrence of one or more adverse events enumerated in the agreement. The
agreements provide for payment of performance awards under the Long-Term
Incentive Program, continuation of health and life benefits for 24 or 36 months,
as appropriate, vesting of accrued retirement benefits, payment of the amount
required to cover excise taxes, if any, financial counseling, outplacement, and
accounting fees and costs of legal representation if required to enforce the
agreement. Mr. Wolfe's agreement includes a provision for payment of the same
severance compensation if his employment is terminated within three years after
a change-in-control of Aerojet. The severance agreements renew annually unless
terminated pursuant to their provisions.

     Omnova Solutions will either assume current GenCorp severance agreements
with appropriate modifications or will enter into severance agreements with
Omnova Solutions officers who currently are not parties to such agreements.
Agreements for Messrs. Yasinsky and Mass each will include a requirement that
any amount which may become payable under the severance agreement be offset by
any amount which may be paid under the individual executive's employment
agreement as a result of termination of employment due to a change-in-control.
Mr. Yasinsky's agreement will provide that he may terminate his employment for
any reason, or without reason, during the 30-day period immediately following
the date six months after the occurrence of a change-in-control, with the right
to severance compensation under this agreement.

ITEM 7. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

     Omnova Solutions is wholly owned by GenCorp, and its results have been
included in GenCorp's consolidated financial results. After the Distribution,
the results of operations of Omnova Solutions will no longer be consolidated
with GenCorp and Omnova Solutions will be an independent public company.
Furthermore, except as described below, all contractual relationships existing
prior to the Distribution between GenCorp after the Distribution (sometimes
referred to as New GenCorp) and Omnova Solutions will be terminated except for
commercial relationships in the ordinary course of business.

     Prior to the Distribution, GenCorp and Omnova Solutions will enter into
certain agreements, described below, governing their relationship subsequent to
the Distribution and providing for the allocation of tax and other liabilities
and obligations arising from periods prior to the Distribution. Each of GenCorp
and Omnova Solutions believes that the agreements are fair.

                                       33
<PAGE>   34

     Copies of the forms of the material agreements have been or will be filed
as exhibits to this Registration Statement on Form 10. The following description
summarizes the material terms of these agreements.

DISTRIBUTION AGREEMENT

     GenCorp and Omnova Solutions will enter into a distribution agreement
providing for, among other things, corporate transactions required to effect the
Distribution and other arrangements between GenCorp and Omnova Solutions with
respect to or in consequence of the Distribution.

     The distribution agreement will provide for, with certain exceptions, (1)
the contribution of assets to Omnova Solutions by GenCorp, and (2) assumptions
of liabilities and cross-indemnities designed principally to place financial
responsibility for the liabilities of GenCorp and its subsidiaries other than
Omnova Solutions with New GenCorp and financial responsibilities for the
liabilities to be assumed by Omnova Solutions with Omnova Solutions. Each of New
GenCorp and Omnova Solutions will have sole responsibility for claims arising
out of its respective activities after the Distribution. Further, the
distribution agreement will provide that New GenCorp and Omnova Solutions will
not take any action to cause the Distribution to be taxable to GenCorp or its
shareholders, and that New GenCorp and Omnova Solutions will indemnify each
other for any adverse consequences incurred as a result of their breach of that
obligation to the other.

     The distribution agreement will also provide that each of New GenCorp and
Omnova Solutions will be granted mutual access to certain historical records and
information in the possession of the other, and requires the retention by each
of New GenCorp and Omnova Solutions for a period of six years following the
Distribution of all information in its possession, and thereafter requires that
each party give the other prior notice of its intention to dispose of the
information.

     The distribution agreement will also provide that, except as otherwise set
forth therein or in any other agreement, all costs or expenses incurred on or
prior to the Distribution date in connection with the Distribution will be
charged to and paid by the party incurring the costs or expenses. Except as set
forth in the Distribution Agreement or any related agreement, each party will
bear its own costs and expenses incurred after the Distribution.

TAX MATTERS AGREEMENT

     As part of the Distribution, GenCorp and Omnova Solutions will enter into a
tax matters agreement that will provide, among other things, for the allocation
of Federal, state, local and foreign tax liabilities for periods prior to and
including the Distribution date. Through the Distribution date, Omnova Solutions
has been and will be included in GenCorp's consolidated Federal income tax
returns and, in certain states, GenCorp's state tax returns. In general, the tax
matters agreement will provide that New GenCorp will be liable for taxes related
to GenCorp, New GenCorp and Omnova Solutions for all periods prior to the
Distribution. In addition, New GenCorp will be entitled to all refunds related
to GenCorp, New GenCorp and Omnova Solutions for all periods prior to the
Distribution. Though valid as between New GenCorp and Omnova Solutions, the tax
matters agreement is not binding on the IRS and does not affect the several
liability of GenCorp and Omnova Solutions for all federal income taxes of the
consolidated group required to be shown on the consolidated Federal income tax
returns.

ALTERNATIVE DISPUTE RESOLUTION AGREEMENT

     GenCorp and Omnova Solutions will enter into an alternative dispute
resolution agreement establishing procedures for resolving disputes that may
arise between them after the Distribution. The alternative dispute resolution
agreement will provide for both mediation and arbitration, which would be the
exclusive methods for resolution of most disputes between the parties that arise
prior to the Distribution or in connection with the Distribution and would
reduce the possibility of litigation between them.

                                       34
<PAGE>   35

AGREEMENT ON EMPLOYEE MATTERS

     GenCorp and Omnova Solutions will enter into an agreement on employee
matters providing for the treatment of employee benefit matters and other
compensation arrangements for former and current employees of Omnova Solutions
and its subsidiaries.

     OMNOVA SOLUTIONS SALARIED PENSION PLAN. Prior to the Distribution, Omnova
Solutions will establish its own pension plan for the benefit of its active
salaried employees and those former salaried employees who terminated employment
from active business locations of Omnova Solutions. The terms of the Omnova
Solutions salaried pension plan will be substantially identical to the GenCorp
salaried pension plan. Omnova Solutions employees who participate in the GenCorp
salaried pension plan will be eligible for immediate participation in the Omnova
Solutions salaried pension plan. Omnova Solutions salaried employees also will
be credited under the Omnova Solutions salaried pension plan, for eligibility
and vesting purposes, with service credited to them under the GenCorp salaried
pension plan. Those assets and liabilities of the GenCorp salaried pension plan
which are attributable to Omnova Solutions plan participants (including a pro
rata share of surplus plan assets) will be transferred from the GenCorp salaried
pension plan to the Omnova Solutions salaried pension plan in connection with
the Distribution, following which the Omnova Solutions salaried employees will
receive benefit service with respect to service credited to them under the
GenCorp salaried pension plan. These transfers will result in Omnova Solutions
having estimated prepaid pension cost, based on actuarial estimates, of
approximately $26 million.

     OMNOVA SOLUTIONS HOURLY PENSION PLAN. Prior to the Distribution, Omnova
Solutions will establish its own pension plan for the benefit of its active
hourly employees and those former hourly employees who terminated employment
from active business locations of Omnova Solutions. The terms of the Omnova
Solutions hourly pension plan will be substantially identical to the GenCorp
hourly pension plan. Omnova Solutions employees who participate in the GenCorp
hourly pension plan will be eligible for immediate participation in the Omnova
Solutions hourly pension plan. Omnova Solutions employees also will be credited
under the Omnova Solutions hourly pension plan, for eligibility and vesting
purposes, with service credited to them under the GenCorp hourly pension plan.
Those assets and liabilities of the GenCorp hourly pension plan which are
attributable to the Omnova Solutions hourly plan participants (including a pro
rata share of surplus plan assets) will be transferred from the GenCorp hourly
pension plan to the Omnova Solutions hourly pension plan in connection with the
Distribution, following which the Omnova Solutions hourly employees will receive
benefit service with respect to service credited to them under the GenCorp
hourly pension plan. These transfers will result in Omnova Solutions having
estimated prepaid pension cost, based on actuarial estimates, of approximately
$9 million.

     POSTRETIREMENT BENEFITS. GenCorp currently provides certain health care and
life insurance benefits to most retired employees in the United States with
varied coverage by employee groups. The health care plans generally provide for
cost sharing in the form of retiree contributions, deductibles and coinsurance
between GenCorp and its retirees. The unfunded benefit obligation reported in
GenCorp's financial statements for such postretirement benefits will be
allocated between New GenCorp and Omnova Solutions as follows: (1) approximately
$303 million for active employees remaining New GenCorp employees and former
employees who do not become employees of Omnova Solutions will be retained by
New GenCorp; and (2) approximately $46 million for active employees transferred
to Omnova Solutions and former employees who terminated employment from active
business locations of Omnova Solutions will be assumed by Omnova Solutions.

     JOINT SAVINGS PLAN. As of the Distribution, the GenCorp retirement savings
plans will become a multiple employer plan in which both New GenCorp and Omnova
Solutions will be unrelated participating employers. On and after the date of
the special dividend contemplated by the Distribution, employer matching
contributions on behalf of New GenCorp employees will be made solely by New
GenCorp and solely to the New GenCorp stock fund, and employer matching
contributions on behalf of Omnova Solutions employees will be made solely by
Omnova Solutions and solely to the Omnova Solutions stock fund. Not later than
the later of October 31, 2001 or two years after the Distribution, the accounts
of Omnova Solutions employees and former Omnova Solutions employees will be
transferred to a new separate savings plan to be established by Omnova
Solutions. Thereafter, neither Omnova Solutions nor its employees will
participate in the New GenCorp retirement savings plan.

     Omnova Solutions common stock held in the accounts of New GenCorp employees
that is attributable to contributions made before the Distribution may be
retained in the Omnova Solutions stock fund, transferred to the New GenCorp
stock fund or transferred to any other investment funds in the retirement
savings plan at the participant's election in accordance with the terms of the
retirement savings plan. Except as provided in the preceding sentence,
contributions made to or held under the retirement savings plan on behalf of New
GenCorp employees may not be invested in the Omnova Solutions stock fund. Any
dividends on Omnova Solutions common stock in accounts of New GenCorp employees
will be reinvested in the Omnova Solutions stock fund.

     New GenCorp common stock held in the accounts of Omnova Solutions employees
that is attributable to contributions made before the Distribution may be
retained in the New GenCorp stock fund, transferred to the Omnova Solutions
stock fund or transferred to any other investment fund in the retirement savings
plan at the participant's election in accordance with the term of the retirement
savings plan. Except as provided in the preceding sentence, contributions made
to or held under the retirement savings plan on behalf of Omnova Solutions
employees may not be invested in the New GenCorp stock fund. Any dividends after
the Distribution date on New GenCorp common stock in accounts of Omnova
Solutions employees will be reinvested in the New GenCorp stock fund.

     STOCK INCENTIVE COMPENSATION PLAN. Prior to the Distribution date, the
GenCorp Inc. Stock Incentive Compensation Plan will be terminated, and all
accounts of participants, whether represented by GenCorp shares held in a trust
or cash payment obligations will be distributed to participants, subject to the
normal tax withholding provisions in the plan.

     GENCORP 1993 AND 1997 STOCK OPTION PLANS. Prior to the date of the special
dividend contemplated by the Distribution, exercisable options under the GenCorp
1993 and 1997 Stock Option Plans for (1) active employees, (2) retirees, and (3)
other former employees whose options remain exercisable, will be split into
options to acquire New GenCorp common stock and Omnova Solutions common stock.
Except with respect to options held by the chief executive officers of New
GenCorp and Omnova Solutions, the number of exercisable options in each company
will each equal the number of exercisable options under the GenCorp Stock Option
Plans. With respect to exercisable options held by the chief executive officers,
(1) Mr. Wolfe's options will be converted into 66 2/3% New GenCorp options and
33 1/3% Omnova Solutions options, and (2) Mr. Yasinsky's options will be
converted into 66 2/3% Omnova Solutions options and 33 1/3% New GenCorp options.
The exercise price of each resulting option will bear the same ratio to the
market price, as of the date of the special dividend contemplated by the
Distribution, of the respective company's stock, as the exercise price of the
original GenCorp option bore to the market price of GenCorp shares immediately
before the Distribution date.

     Unexercisable options under the GenCorp 1997 Stock Option Plan for New
GenCorp employees will be replaced with a number of unexercisable New GenCorp
options under that plan which will, based upon (1) the market price of GenCorp
shares immediately after the date of the special dividend contemplated by the
Distribution and (2) the exercise prices for those options, have an aggregate
intrinsic value equal to that of the unexercisable GenCorp options immediately
before the date of the special dividend contemplated by the Distribution.

     Unexercisable options under the GenCorp 1997 Stock Option Plan for Omnova
Solutions employees will be replaced with a number of unexercisable Omnova
Solutions options which will, based upon (1) the market price of Omnova
Solutions shares immediately after the date of the special dividend contemplated
by the Distribution and (2) the exercise price for such options, have an
aggregate intrinsic value equal to that of the unexercisable GenCorp options
immediately before the date of the special dividend contemplated by the
Distribution.

     In converting the stock option plans for the Distribution, the exercisable
and unexercisable aggregate intrinsic value of the options immediately after the
conversion will be equal to the aggregate intrinsic value immediately before the
conversion. The ratio of the exercise price per option to the market value per
share will not be reduced and the vesting provisions and option period of the
Omnova Solutions and New GenCorp options will be the same as for the original
GenCorp options. Accordingly, no compensation expense will be recognized by
Omnova Solutions or New GenCorp.

                                       36

     UNFUNDED DEFERRED COMPENSATION. GenCorp has unfunded obligations to pay
deferred compensation and retirement income under its Benefits Restoration Plan,
Deferred Bonus Plan, Non-Employee Directors Retirement and Deferred Compensation
Plans, 1996 Supplemental Retirement Plan for Management Employees, individual
employment agreements, and other miscellaneous plans related to discontinued
operations. Subject to legal requirements for employee acquiescence, benefit
obligations for (1) active employees transferred to Omnova Solutions, (2)
retired employees who terminated employment from active business locations of
Omnova Solutions, and (3) GenCorp directors resigning to become members of the
Omnova Solutions Board, will be assumed by Omnova Solutions. Benefit obligations
for (4) active employees remaining New GenCorp employees, (5) GenCorp directors
remaining on the New GenCorp Board, (6) other retired employees, and (7) retired
directors, will be retained by New GenCorp.

     Former employees and directors will be able to elect a lump-sum payment of
their deferred compensation, subject to (1) a 10% reduction in order to avoid
adverse tax consequences, and (2) all applicable tax withholding. Active
employees and directors may receive lump-sum payments upon termination of
employment or board service with GenCorp, New GenCorp or Omnova Solutions based
upon appropriate advance elections or discretionary approval by the appropriate
company's benefit management committee. Under the agreement on employee matters,
New GenCorp will indemnify the payment of unfunded obligations assumed by Omnova
Solutions as of the date of the special dividend contemplated by the
Distribution, and Omnova Solutions will indemnify the payment of unfunded
obligations retained by New GenCorp as of the date of the special dividend
contemplated by the Distribution.

     ANNUAL BONUSES. Bonus amounts under GenCorp's Executive Incentive
Compensation Plan for the period ending November 30, 1999 will be determined
based upon (1) actual performance up to the date of the special dividend
contemplated by the Distribution, and (2) budgeted performance, for the
remainder of the period, according to GenCorp's annual operating plan. Subject
to legal requirements for employee acquiescence, bonus obligations will be
assumed by Omnova Solutions for all Omnova Solutions employees, and paid in
cash. Bonus obligations will be paid in cash by New GenCorp for all New GenCorp
employees and for terminated GenCorp employees who are not employed by Omnova
Solutions.

     LONG-TERM INCENTIVE COMPENSATION. Performance awards under GenCorp's
Long-Term Incentive Program for the three-year performance period ending
November 30, 1999 will be determined based upon (1) actual performance up to the
date of the special dividend contemplated by the Distribution, and (2) budgeted
performance, for the remainder of the period, according to GenCorp's annual
operating plan. Pro rata performance awards will be paid under the GenCorp plan
for the performance periods ending November 30, 2000 and November 30, 2001. Pro
rata performance awards for each partial performance period will be determined
based upon (1) actual performance up to the date of the special dividend
contemplated by the Distribution, and (2) budgeted performance, for the
remainder of the fiscal year ending November 30, 1999, according to GenCorp's
annual operating plan. Subject to legal requirements for employee acquiescence,
performance award obligations will be assumed by Omnova Solutions for all Omnova
Solutions employees and paid in cash. Performance award obligations will be paid
in cash by New GenCorp for all New GenCorp employees and for terminated GenCorp
employees who are not employed by Omnova Solutions.

     DIRECTOR COMPENSATION. Subject to legal requirements for director
acquiescence, benefit obligations for GenCorp directors resigning to become
members of the Omnova Solutions Board will be assumed by Omnova Solutions.
Benefit obligations for GenCorp directors remaining on the New GenCorp Board and
retired directors will be retained by New GenCorp.

     ENHANCED RETIREMENT AND SEPARATION PAY PLANS. GenCorp adopted a Voluntary
Enhanced Retirement Program (VERP) and Enhanced Involuntary Separation Pay Plan
(EISP) which are associated with and contingent upon the Distribution. The VERP
offers enhanced retirement benefits to eligible salaried employees within a
number of corporate facilities and divisional headquarters. The majority of the
related benefits will be paid from the defined benefit pension and retiree
health care plans of New GenCorp and Omnova Solutions. The maximum estimated
cost of the VERP could range up to $7.6 million. The maximum estimated cost of
the EISP could range up to $2.1 million. The actual cost of both the VERP and
the EISP will be reflected in the financial

                                       37
<PAGE>   38

statements of GenCorp prior to the Distribution. The total number of
participants and the timing of their departure are not yet known.

     ADMINISTRATIVE SERVICES. For a transition period not to exceed two years
after the Distribution, the Joint Savings Plan and other benefit programs
currently applicable to GenCorp active employees and retirees will be
administered under a transition services arrangement between New GenCorp and
Omnova Solutions. The purpose of the transition services arrangement will be to
allow for an orderly transition of administrative responsibility for ongoing
GenCorp benefit programs to administrative staffs of New GenCorp and Omnova
Solutions. In accordance with the transition services agreement, Omnova
Solutions will reimburse New GenCorp, and New GenCorp will reimburse Omnova
Solutions, for all direct and indirect costs incurred by each to provide these
services on terms believed by New GenCorp and Omnova Solutions to be
commercially reasonable.

     With respect to other employee welfare benefit plans, policies, contracts
and arrangements of GenCorp, such as GenCorp's medical reimbursement and
vacation, sick leave and jury duty policies, the agreement on employee matters
will generally provide that Omnova Solutions will adopt, and be solely
responsible for substantially identical, plans, policies, contracts and
arrangements, to be effective from and after the date of the special dividend
contemplated by the Distribution, with respect to individuals who will be
employees of Omnova Solutions and their beneficiaries after the date of the
special dividend contemplated by the Distribution. The agreement on employee
matters also will provide that service with GenCorp prior to the date of the
special dividend contemplated by the Distribution will be counted for purposes
of participation, vesting and, following appropriate asset transfers, benefit
accruals under the plans, policies, contracts and arrangements of Omnova
Solutions following the date of the special dividend contemplated by the
Distribution.

INTELLECTUAL PROPERTY

     In connection with the Distribution, intellectual property, including
patents, trademarks, copyrights, trade secrets and inventions used primarily by,
or being developed primarily for, Performance Chemicals and Decorative &
Building Products will be transferred to Omnova Solutions. In addition, a
license agreement will be established, subject to the rights of the U.S.
government, allowing Omnova Solutions to pursue commercialization of fluorinated
oxetane technology and associated oxetane technology originally conceived by
Aerojet, in Omnova Solutions' areas of interest and allowing New GenCorp to
pursue the technology in its areas of interest.

TRANSITION SERVICES AGREEMENT

     GenCorp and Omnova Solutions will enter into a transition services
agreement which will provide for Omnova Solutions to continue to supply to New
GenCorp, for periods generally not to exceed two years and subject to
conditions, transitional administrative services for Vehicle Sealing operations,
including accounts receivable collections, payroll, real estate, data
communications and word processing, and to assist in effecting an orderly
transition following the Distribution. Omnova Solutions will be entitled to
reimbursement for all direct and indirect costs of providing these transitional
services on terms believed by Omnova Solutions and New GenCorp to be
commercially reasonable. These costs are not expected to be material.

ITEM 8. LEGAL PROCEEDINGS.

     Omnova Solutions is subject to various legal actions, governmental
investigations, and proceedings relating to a wide range of matters. In the
opinion of management, after reviewing the information which is currently
available with respect to these matters and consulting with counsel, any
liability which may ultimately be incurred with respect to these matters will
not materially affect the consolidated financial condition of Omnova Solutions.
The effect of resolution of these matters on results of operations cannot be
predicted because any effect depends on both future results of operations and
the amount and timing of the resolution of these matters.

                                       38

ITEM 9. MARKET PRICE OF AND DIVIDENDS ON THE REGISTRANT'S COMMON EQUITY AND
RELATED STOCKHOLDER
MATTERS.


     Omnova Solutions has applied to the NYSE for the listing of the Omnova
Solutions common stock. Omnova Solutions initially will have approximately
12,032 shareholders of record based upon the number of shareholders of record of
GenCorp as of August 31, 1999. It is presently anticipated that Omnova Solutions
common stock will be approved for listing on the NYSE prior to the Distribution
date, and trading may commence on a "when-issued" basis prior to the
Distribution. It is also possible that New GenCorp common stock would be traded
on a "when-distributed" basis prior to the Distribution. On the trading day
following the date that certificates for Omnova Solutions common stock are
mailed by the Distribution agent, "when-issued" or "when-distributed" trading,
as applicable, in respect of each of the Omnova Solutions common stock and New
GenCorp common stock would end and "regular-way" trading would begin. The NYSE
will not approve any trading of the Omnova Solutions common stock until the
Securities and Exchange Commission (the "Commission") has declared effective
this Form 10.


     There is now no public market for Omnova Solutions common stock. Prices at
which Omnova Solutions common stock may trade prior to the Distribution on a
"when-issued" or "when-distributed" basis or after the Distribution cannot be
predicted. Until the Omnova Solutions common stock is fully distributed and an
orderly market develops, the prices at which trading in Omnova Solutions common
stock occurs may fluctuate significantly. The price at which Omnova Solutions
common stock trades after the Distribution will be determined by the marketplace
and may be influenced by many factors, including, among others, the depth and
liquidity of the market for Omnova Solutions common stock, investor perception
of Omnova Solutions and the industries in which it participates, Omnova
Solutions' operating results, Omnova Solutions' dividend policy and general
economic and market conditions. Market prices may also be affected by provisions
of Omnova Solutions' articles of incorporation and code of regulations as each
will be in effect following the Distribution, which may have an antitakeover
effect. See "Item 11. Description of Registrant's Securities to be
Registered -- Certain Change in Control Effects of Certain Provisions of the
Articles of Incorporation and Code of Regulations of Omnova Solutions".

     The Omnova Solutions common stock distributed to holders of GenCorp common
stock in the Distribution will be freely transferable, except for shares
received by persons who may be deemed to be "affiliates" of Omnova Solutions
under the Securities Act of 1933. Persons who may be deemed to be affiliates of
Omnova Solutions after the Distribution generally include individuals or
entities that control, are controlled by, or are under common control with
Omnova Solutions and include directors and executive officers of Omnova
Solutions. Persons who are affiliates of Omnova Solutions will be permitted to
sell their shares of Omnova Solutions common stock only pursuant to an effective
registration statement under the Securities Act or an exemption from the
registration requirements of the Securities Act, such as the exemption afforded
by Section 4(2) of the Securities Act or by Rule 144.

     The Bank of New York will act as the transfer agent and registrar for the
Omnova Solutions common stock after the Distribution is completed.

     The dividend policy of Omnova Solutions will be determined by the Omnova
Solutions Board. The payment and level of any cash dividends by Omnova Solutions
after the Distribution will be subject to the discretion of the Omnova Solutions
Board of Directors. Future dividend decisions will depend on a number of
factors, including the future results of operations and financial condition of
Omnova Solutions, state law requirements and other factors. Although there can
be no assurance that Omnova Solutions will pay any dividends, management of
Omnova Solutions intends to pay cash dividends and believes that its cash flows
after the Distribution should be sufficiently strong that, barring unforeseen
circumstances, a cash dividend can be paid for the foreseeable future. It is
anticipated that Omnova Solutions' credit arrangements after the Distribution
will limit its ability to pay dividends.

ITEM 10. RECENT SALES OF UNREGISTERED SECURITIES.

     Effective June 30, 1999, Omnova Solutions issued to GenCorp 10 shares of
Omnova Solutions common stock in exchange for $1,000. This issuance was exempt
from registration under Section 4(2) of the Securities Act of 1933 because it
was a transaction not involving a public offering.

ITEM 11. DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.

AUTHORIZED CAPITAL STOCK

     After the Distribution, Omnova Solutions' authorized capital stock will
consist of 150,000,000 shares of common stock, $0.10 par value per share, and
15,000,000 shares of preferred stock, $1.00 par value per share. Based on the
number of shares of GenCorp common stock outstanding on June 30, 1999,
approximately 41,817,650 shares of Omnova Solutions common stock will be
transferred by GenCorp to its shareholders in the Distribution. Currently, there
are no shares of Omnova Solutions preferred stock outstanding.

OMNOVA SOLUTIONS COMMON STOCK

     Subject to rights of any holders of preferred stock, each outstanding share
of Omnova Solutions common stock will be entitled to such dividends as may be
declared from time to time by the Board of Directors of Omnova Solutions. See
"Dividend Policies -- Omnova Solutions Dividend Policy." Each outstanding share
of Omnova Solutions common stock will be entitled to one vote on all matters
submitted to a vote of shareholders. After the Distribution, pursuant to the
Omnova Solutions Articles of Incorporation, holders of Omnova Solutions common
stock will not have the right to cumulative voting; therefore, the holders of a
majority of the shares voting for the election of the Board of Directors of
Omnova Solutions will be able to elect all the directors standing for election,
if they so choose. In the event of liquidation, dissolution or winding up of
Omnova Solutions, holders of Omnova Solutions common stock will be entitled to
receive on a pro rata basis any assets remaining after provision for payment of
creditors and any holders of Omnova Solutions Preferred Stock.

NO PREEMPTIVE RIGHTS

     Except as may be provided in any Preferred Stock Designation, no holder of
any class of stock of Omnova Solutions authorized at the time of the
Distribution will have any preemptive right to subscribe to any securities of
Omnova Solutions of any kind.

CERTAIN ANTI-TAKEOVER PROVISIONS RELATING TO OMNOVA SOLUTIONS

     Omnova Solutions' articles of incorporation contain several provisions that
may make the acquisition of control of Omnova Solutions by means of a tender
offer, open market purchase, proxy fight, or otherwise more difficult including
provisions that (1) establish shares of authorized but unissued common stock,
(2) authorize the Omnova Solutions Board to determine certain terms and rights
of unissued preferred stock, and (3) require a supermajority vote for amendment
of certain provisions of the articles of incorporation. Omnova Solutions' code
of regulations also contain provisions that could have an anti-takeover effect,
including provisions that (1) establish a "staggered" Board of Directors, (2)
restrict the ability of shareholders to remove directors except in certain
limited circumstances, (3) require advance notice for shareholder proposals and
nominations for directors, (4) require a supermajority vote for certain
provisions of the code of regulations. In addition, Omnova Solutions is subject
to Section 1701.831 and Chapter 1704 of the Ohio General Corporation Law, both
of which contain takeover-related provisions.

     These provisions of Omnova Solutions' articles of incorporation and code of
regulations are designed to encourage persons seeking to acquire control of
Omnova Solutions to negotiate the terms with the Omnova Solutions Board. Omnova
Solutions believes that, as a general rule, the interest of Omnova Solutions
shareholders would be served best if any change in control results from
negotiations with the Omnova Solutions Board based upon careful consideration of
the proposed terms, such as the price to be paid to shareholders, the form of
consideration to be paid and the anticipated tax effects of the transaction.

                                       40
<PAGE>   41

     The provisions could, however, have the effect of discouraging a
prospective acquiror from making a tender offer or otherwise attempting to
obtain control of Omnova Solutions. To the extent that these provisions
discourage takeover attempts, they could deprive shareholders of opportunities
to realize takeover premiums for their shares. Moreover, these provisions could
discourage accumulations of large blocks of Omnova Solutions common stock, thus
depriving shareholders of any advantages which large accumulations of stock
might provide.

     Set forth below is a summary of the relevant provisions of Omnova
Solutions' articles of incorporation and code of regulations and certain
applicable sections of the Ohio General Corporation Law. Such summary does not
purport to be complete and is subject to, and is qualified in its entirety by
reference to, all of the provisions of Omnova Solutions' articles of
incorporation and code of regulations, which have been filed as exhibits to this
Form 10.

  CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED COMMON STOCK

     One of the effects of the existence of unissued and unreserved Omnova
Solutions common stock may be to enable the Omnova Solutions Board to render
more difficult or to discourage an attempt to obtain control of Omnova Solutions
by means of a merger, tender offer, proxy contest or otherwise, and thereby to
protect the continuity of Omnova Solutions' management. If, in the due exercise
of its fiduciary obligations, for example, the Omnova Solutions Board were to
determine that a takeover proposal was not in Omnova Solutions' best interests,
such shares could be issued by the Omnova Solutions Board without shareholder
approval in one or more private placements or other transactions that might
prevent or render more difficult or costly the completion of the takeover
transaction by diluting the voting or other rights of the proposed acquiror or
insurgent shareholder or shareholder group, by creating a substantial voting
block in institutional or other hands that might undertake to support the
position of the incumbent Omnova Solutions Board, or by effecting an acquisition
that might complicate or preclude the takeover.

     Although Ohio law and the Omnova Solutions Articles would not require
shareholder approval to issue authorized shares, the NYSE, on which the Omnova
Solutions common stock is expected to be listed, requires shareholder approval
of certain issuances as a condition of listing the additional shares or, in some
instances, of continued listing of the outstanding shares.

  PREFERRED STOCK

     The Omnova Solutions articles of incorporation establish three series of
Omnova Solutions preferred stock, and authorize the Omnova Solutions Board to
determine, with respect to any series, the terms and rights of such series
(other than voting), including dividend and liquidation rights.

     The provisions authorizing the Omnova Solutions Board to issue Omnova
Solutions preferred stock in series with such terms as it may designate will
provide Omnova Solutions with flexibility in structuring possible future
financings and acquisitions, and in meeting other corporate needs which might
arise. The authorized shares of Omnova Solutions preferred stock, as well as
shares of Omnova Solutions common stock, will be available for issuance without
further action by shareholders, unless such action is required by applicable law
or the rules of the NYSE. Those rules require shareholder approval as a
prerequisite to listing shares in several instances, including where the present
or potential issuance of shares could result in an increase in the number of
shares of common stock, or in the amount of voting securities outstanding of at
least 20%.

     Although the Omnova Solutions Board has no present intention of doing so,
it could issue a series of Omnova Solutions preferred stock that could,
depending on its terms, impede the completion of a takeover attempt, including
one in which shareholders might receive a premium for their stock over the then
current market price.

  CONTROL SHARE ACQUISITIONS

     Section 1701.831 of the Ohio General Corporation Law provides that certain
notice and informational filings and special shareholder meeting and voting
procedures must be followed prior to consummation of a proposed

                                       41
<PAGE>   42

"control share acquisition." The Ohio General Corporation Law defines a "control
share acquisition" as any acquisition of an issuer's shares which would entitle
the acquiror, immediately after that acquisition, directly or indirectly, to
exercise or direct the exercise of voting power of the issuer in the election of
directors within any of the following ranges of that voting power:

          - one-fifth or more but less than one-third of that voting power;

          - one-third or more but less than a majority of that voting power; or

          - a majority or more of that voting power.

     Assuming compliance with the notice and information filings prescribed by
statute, the proposed control share acquisition may be made only if, at a
special meeting of shareholders, the acquisition is approved by both a majority
of the voting power of the issuer represented at the meeting and a majority of
the voting power remaining after excluding the combined voting power of the
"interested shares." "Interested shares" are the shares held by the intended
acquiror, the employee-directors and officers of the issuer as well as certain
shares that were acquired after the date of the first public disclosure of the
acquisition but before the record date for the shareholders meeting and shares
that were transferred, together with the voting power thereof, after the record
date for the shareholders meeting.

  BUSINESS COMBINATIONS WITH CERTAIN PERSONS

     Omnova Solutions is subject to Chapter 1704 of the Ohio General Corporation
Law, which prohibits certain business combinations and transactions between an
"issuing public corporation" and an "Ohio law interested shareholder" for at
least three years after the Ohio law interested shareholder attains 10%
ownership, unless the board of directors of the issuing public corporation
approves the transaction before the Ohio law interested shareholder attains 10%
ownership. An "issuing public corporation" is an Ohio corporation with 50 or
more shareholders that has its principal place of business, principal executive
offices, or substantial assets within the State of Ohio, and as to which no
close corporation agreement exists. An "Ohio law interested shareholder" is a
beneficial owner of 10% or more of the shares of a corporation. Examples of
transactions regulated by Chapter 1704 include the disposition of assets,
mergers and consolidations, voluntary dissolutions and the transfer of shares.

     Subsequent to the three-year period, a transaction subject to Chapter 1704
may take place provided that certain conditions are satisfied, including:

          - prior to the interested shareholder's share acquisition date, the
            board of directors approved the purchase of shares by the interested
            shareholder;

          - the transaction is approved by the holders of shares with at least
            66 2/3% of the voting power of the corporation (or a different
            proportion set forth in the articles of incorporation), including at
            least a majority of the outstanding shares after excluding shares
            controlled by the Ohio law interested shareholder; or

          - the business combination results in shareholders, other than the
            Ohio law interested shareholder, receiving a fair price plus
            interest for their shares.

     Chapter 1704 is applicable to all corporations formed under Ohio law.

  CLASSIFIED BOARD OF DIRECTORS

     The Omnova Solutions code of regulations provides for the Omnova Solutions
Board to be divided into three classes of directors, as nearly equal in number
as possible, serving staggered terms. Approximately 1/3 of the Board is to be
elected each year. See "Item 5. Directors and Executive Officers --
Classification of Omnova Solutions Board."

     The provision for a classified board could prevent a party who acquires
control of a majority of the outstanding voting stock from obtaining control of
the Omnova Solutions Board until the second annual shareholders meeting
following the date the acquiror obtains a controlling stock interest. The
classified board

                                       42
<PAGE>   43

provision could have the effect of discouraging a potential acquiror from making
a tender offer or otherwise attempting to obtain control of Omnova Solutions and
could increase the likelihood that incumbent directors will retain their
positions.

     Omnova Solutions believes that a classified board will help to assure the
continuity and stability of the Omnova Solutions Board and Omnova Solutions'
business strategies and policies as determined by the Omnova Solutions Board,
because a majority of the directors will eventually have prior experience as
directors of Omnova Solutions.

     The classified board provisions should also help to ensure that the Omnova
Solutions Board, if confronted with an unsolicited proposal from a third party
that has acquired a block of the voting stock of Omnova Solutions, will have
sufficient time to review the proposal and appropriate alternatives and to seek
the best available result for all shareholders.

  NUMBER OF DIRECTORS; REMOVAL; VACANCIES

     The Omnova Solutions code of regulations provides that the number of
directors shall be set either by resolution of the Omnova Solutions Board
adopted by the affirmative vote of a majority of the Omnova Solutions Board or
by the affirmative vote of the holders of at least 80% of the voting power of
Omnova Solutions, voting together as a single class; provided that the number of
directors shall not be fewer than seven or greater than 17.

     Pursuant to the Omnova Solutions code of regulations, each director will
serve until his or her successor is duly elected and qualified, unless he or she
resigns, dies, becomes disqualified, or is removed. Omnova Solutions' code of
regulations prohibits the removal of directors from the Omnova Solutions Board
by the shareholders. Further, the Omnova Solutions code of regulations prohibits
removal of directors by the directors, except when the director to be removed:

          - has been found by a court of competent jurisdiction to be of unsound
            mind, or if he or she is adjudicated bankrupt;

          - has failed to qualify as a director by accepting in writing his or
            her election or by acting at a meeting of the Omnova Solutions
            Board;

          - is unable to engage in any substantial gainful activity by reason of
            any medically determinable physical or mental impairment that is
            expected to be permanent;

          - has, since his or her election as a director, been convicted of a
            crime constituting a felony or involving fraud, embezzlement or
            theft; or

          - has, since his or her election as a director, been found by a court
            of competent jurisdiction in a civil action to have breached his or
            her duty of loyalty to the company or any other company.

     The Omnova Solutions code of regulations further provides that generally
vacancies or newly created directorships in the Omnova Solutions Board may only
be filled by a resolution approved by a majority of the Omnova Solutions Board
and any director so chosen will hold office until the next election of the class
for which such director was chosen.

  SHAREHOLDER ACTION; SPECIAL MEETINGS

     Under the Ohio General Corporation Law, unless prohibited by the articles
of incorporation or the code of regulations, any action by shareholders
generally must be taken at a meeting, unless a written consent stating the
action to be taken is signed by all the shareholders who would be entitled to
notice of the meeting held to consider the subject matter of the written
consent. Omnova Solutions' code of regulations does not prohibit shareholders
from acting by written consent.

     Under the Ohio General Corporation Law, a special meeting of shareholders
may be called by the chairman, the president, the directors by action at a
meeting, a majority of the directors voting without a meeting, persons owning
25% of the outstanding shares entitled to vote at that meeting, or a less or
greater proportion as specified in the articles or regulations but not greater
than 50%, or the person(s) authorized to do so by the articles of

                                       43
<PAGE>   44

incorporation or the code of regulations. Omnova Solutions' code of regulations
provides that special meetings of shareholders may be called by the Chairman of
the Omnova Solutions Board, the President of Omnova Solutions, a majority of the
directors acting with or without a meeting or by any person or persons who hold
not less than 50% of all shares entitled to vote at that shareholders meeting.

  SHAREHOLDER PROPOSALS AND NOMINATIONS

     Omnova Solutions' code of regulations establishes an advance notice
procedure for shareholder proposals to be brought before an annual or special
meeting of shareholders of Omnova Solutions, including proposed nominations of
persons for election to the Omnova Solutions Board. Shareholders at an annual or
special meeting may only consider proposals or nominations brought before the
meeting by Omnova Solutions, by or at the direction of the Board or by a
shareholder that was a shareholder of record on the record date for the meeting,
that is entitled to vote at the meeting and that has given to Omnova Solutions'
Secretary timely written notice, in proper form, of the shareholder's intention
to bring that business before the meeting.

     To be timely, notice by shareholders of nominations or proposals to be
brought before any annual meeting of shareholders, or before any special meeting
of shareholders, must be delivered to the Secretary of Omnova Solutions not less
than 60 nor more than 90 calendar days prior to the first anniversary of the
date on which Omnova Solutions first mailed its proxy materials for the
preceding year's annual meeting of shareholders, provided, however, that if the
date of the annual meeting is advanced more than 30 calendar days prior to or
delayed by more than 30 calendar days after the anniversary of the preceding
year's annual meeting, notice by the shareholder to be timely must be so
delivered not later than the close of business on the later of the 90th calendar
day prior to such annual meeting or the 10th calendar day following the day on
which public announcement of the date of such meeting is first made.

     Each notice by shareholders must set forth (1) the name and address of the
shareholder who intends to make the nomination or proposal and of any beneficial
owner on whose behalf the nomination or proposal is made and (2) the class and
number of shares of Omnova Solutions common stock that are owned beneficially
and of record by such shareholder and beneficial owner, if any. In the case of a
shareholder proposal, the notice must also set forth a brief description of the
business desired to be brought before the meeting, the reasons for conducting
such business at the meeting and any material interest of such shareholder or
beneficial owner, if any, in that proposed business. In the case of nomination
of any person for election as a director, the notice must also set forth any
information regarding the nominee proposed by the shareholder that would be
required to be included in a proxy statement filed pursuant to the proxy rules
of the Commission and the consent, if so required, of the nominee to be named in
a proxy statement as a candidate for election and to serve as a director of
Omnova Solutions if elected.

     Although Omnova Solutions' code of regulations does not give the Omnova
Solutions Board the power to approve or disapprove shareholder nominations of
candidates or proposals regarding other business to be conducted at a special or
annual meeting, Omnova Solutions' code of regulations may have the effect of
precluding the conduct of certain business at a meeting if the proper procedures
are not followed or may discourage or defer a potential acquiror from conducting
a solicitation of proxies to elect its own slate of directors or otherwise
attempting to obtain control of Omnova Solutions.

  AMENDMENT OF CHARTER DOCUMENTS

     Ohio law permits the adoption of amendments to the articles of
incorporation if those amendments are approved at a meeting held for that
purpose by the holders of shares entitling them to exercise two-thirds of the
voting power of the corporation, or a lesser, but not less than a majority, or
greater vote as specified in the articles of incorporation. Amendment of Omnova
Solutions' articles of incorporation requires the approval of the holders of at
least 66 2/3% of the voting power then outstanding, except that amendment of any
of the following provisions requires the affirmative vote of the holders of
shares of Omnova Solutions entitled to exercise 80% of the voting power of
Omnova Solutions:

          - Article V, which relates to the board's ability to determine the
            terms and rights of series of Omnova Solutions preferred stock;

                                       44
<PAGE>   45

          - Article VI, which relates to the elimination of cumulative voting;

          - Article VII, which relates to the elimination of pre-emptive rights;
            and

          - Article VIII, which relates to the directors' authority to purchase
            any securities of Omnova Solutions.

     Under the Ohio General Corporation Law, a code of regulations may be
adopted, amended or repealed only by approval of the shareholders either at a
meeting of shareholders by the affirmative vote of the holders of shares
entitling them to exercise a majority of the voting power on that proposal or by
written consent signed by holders of shares entitling them to exercise 66 2/3%
of the voting power on that proposal, or if the regulations so provide, by the
affirmative vote or written consent of the holders of shares entitling them to
exercise a greater or lesser proportion, but not less than a majority of the
voting power. Omnova Solutions' code of regulations provides that the code of
regulations may be amended at any meeting of shareholders, provided that any
such amendment proposed for consideration has been described in the notice of
meeting. Omnova Solutions' code of regulations further provides that amendment
of any of the following provisions requires the affirmative vote of the holders
of shares of Omnova Solutions entitled to exercise 80% of the voting power of
Omnova Solutions:

          - Regulation 1, which relates to the time and place of shareholder
            meetings;

          - Regulation 3(a), which relates to the calling of special shareholder
            meetings;

          - Regulation 8, which relates to the order of business at shareholder
            meetings and advance notification requirements for proposals for
            business to be conducted at shareholder meetings;

          - Regulation 10, which relates to the number, term, classification and
            election of directors;

          - Regulation 11, which relates to newly created directorships and
            vacant directorships;

          - Regulation 12, which relates to removal of directors;

          - Regulation 13, which relates to nomination and election of directors
            and advance notification requirements relating thereto; and

          - Regulation 30, which relates to indemnification for directors and
            officers, among others.

  SHARE PURCHASE RIGHTS PLAN

     It is anticipated that the Omnova Solutions Board will consider and may
adopt a share purchase rights plan on or after the Distribution Date.

ITEM 12. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Generally, a director of an Ohio corporation will not be found to have
violated his fiduciary duties unless there is proof by clear and convincing
evidence that the director has not acted in good faith, in a manner he
reasonably believes to be in or not opposed to the best interests of the
corporation, or with the care that an ordinarily prudent person in a like
position would use under similar circumstances. In general, a director is liable
for monetary damages for any action or omission as a director only if it is
proved by clear and convincing evidence that such act or omission was undertaken
either with deliberate intent to cause injury to the corporation or with
reckless disregard for the best interests of the corporation.

     Under Ohio law, a corporation must indemnify its directors, as well as its
officers, employees and agents, against expenses where any such person is
successful on the merits or otherwise in defense of an action, suit or
proceeding. A corporation may indemnify such persons in actions, suits and
proceedings (including derivative suits) if the individual has acted in good
faith and in a manner that he believes to be in or not opposed to the best
interests of the corporation. In the case of a criminal proceeding, the
individual must also have no reasonable cause to believe that his conduct was
unlawful. Indemnification may be made only if ordered by a court or if
authorized in a specific case upon a determination that the applicable standard
of conduct has been met. Such a determination may be made by a majority of the
disinterested directors, by independent legal counsel or by the shareholders. In
order to obtain reimbursement for expenses in advance of the final disposition
of any action, the

                                       45
<PAGE>   46

individual must provide an undertaking to repay the amount if it is ultimately
determined that he is not entitled to be indemnified.

     In general, Ohio law requires that all expenses, including attorney's fees,
incurred by a director in defending any action, suit or proceeding be paid by
the corporation as they are incurred in advance of final disposition if the
director agrees to repay such amounts if it is proved by clear and convincing
evidence that his action or omission was undertaken with deliberate intent to
cause injury to the corporation or with reckless disregard for the best
interests of the corporation and if the director reasonably cooperates with the
corporation concerning the action, suit or proceeding.

     The code of regulations of Omnova Solutions provide for indemnification
that is coextensive with that permitted under Ohio law. In addition, Omnova
Solutions entered into or will enter into agreements that indemnify its
directors and certain of its officers to the maximum extent permitted by
applicable law. The indemnification so granted is not limited to the
indemnification specifically authorized by the Ohio General Corporation Law.
Each agreement represents a contractual obligation of Omnova Solutions which
cannot be altered unilaterally.

ITEM 13. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.

HISTORICAL FINANCIAL STATEMENTS

     The historical financial information required by this item is contained in
the financial statements that are listed on page F-1 of this Form 10 and are
filed herewith.

OMNOVA SOLUTIONS UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

     The following unaudited pro forma condensed combined balance sheet as of
May 31, 1999 and the unaudited pro forma condensed statements of combined income
for the six months ended May 31, 1999 and for the year ended November 30, 1998
give effect to Omnova Solutions as a stand-alone entity. The pro forma condensed
combined balance sheet is presented as if the Distribution had occurred on May
31, 1999, and the pro forma condensed statements of combined income are
presented as if the Distribution and the 1998 acquisitions had occurred as of
the beginning of the periods presented. These pro forma combined financial
statements reflect the anticipated borrowing by Omnova Solutions of
approximately $188 million and the payment of the borrowings by Omnova Solutions
to GenCorp in the form of a dividend. The actual amount to be borrowed by Omnova
Solutions and paid as a dividend to GenCorp will be determined at the time of
the Distribution. The actual amount will depend, in part, on the amount of
borrowings by GenCorp at that time. GenCorp's borrowings fluctuate throughout
its fiscal year. The pro forma information is presented for illustrative
purposes only and is not necessarily indicative of the results that would have
been obtained had the transactions actually occurred on the dates assumed, nor
is it necessarily indicative of the future combined results of operations.

     The pro forma condensed combined financial statements should be read in
conjunction with the historical combined financial statements and the related
notes thereto of Omnova Solutions included in this Form 10.

 OMNOVA SOLUTIONS NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED BALANCE SHEET

                                  MAY 31, 1999

(1) To record the transfer of net pension assets and retiree medical obligations
    and related deferred income taxes from GenCorp to Omnova Solutions. The
    estimated prepaid pension asset is attributable to the excess of pension
    assets over liabilities related to Omnova Solutions employees and retirees.
    The projected prepaid pension asset of $40 million and retiree medical
    benefit obligations of $47 million were actuarially determined based on
    Omnova Solutions' active and retired participants in the plans and the
    actuarial assumptions used were consistent with assumptions previously used
    by GenCorp. The pension assets were split based on the requirements of
    Section 414(i) of the Internal Revenue Code as prescribed by the Pension
    Benefit Guaranty Corporation and other management considerations.

(2) To record the transfer of certain property, plant and equipment, primarily
    GenCorp's corporate headquarters, related liabilities and deferred taxes
    from GenCorp.

(3) Reflects the anticipated borrowing by Omnova Solutions of approximately $188
    million. The proceeds from the borrowing will be used to pay a dividend to
    GenCorp.

(4) To record the effect on divisional equity of the pro forma adjustments
    referred to in notes (1), (2) and (3) above.

                 OMNOVA SOLUTIONS NOTES TO UNAUDITED PRO FORMA
                    CONDENSED STATEMENTS OF COMBINED INCOME

 FOR THE SIX MONTHS ENDED MAY 31, 1999 AND FOR THE YEAR ENDED NOVEMBER 30, 1998

(1) To record the decrease in pension expense attributable to the transfer of a
    portion of the excess of the defined benefit pension plans' assets over the
    related obligations for Omnova Solutions employees and retirees.

(2) To transfer corporate costs that will be assumed by Omnova Solutions as a
    result of the Distribution. This adjustment also includes the cost
    associated with the corporate assets and liabilities transferred from
    GenCorp. After the Distribution, these costs will no longer be incurred by
    GenCorp. These costs, along with the general and administrative costs
    already allocated to Omnova Solutions in its historical combined financial
    statements total approximately $22 million in 1998, which management
    believes are representative of the annual general and administrative costs
    on a stand alone basis.

(3) To adjust interest expense to the amount computed based on the anticipated
    borrowing of $188 million as a result of the Distribution. The interest rate
    was 5.5% and 5.8% for the six months ended May 31, 1999 and for the year
    ended November 30, 1998, respectively. The interest rate was primarily based
    on LIBOR plus a margin as specified in GenCorp's credit agreement. A quarter
    point change in the interest rate would result in a $.2 million and a $.5
    million change in interest expense for the six months ended May 31, 1999 and
    for the year ended November 30, 1998, respectively.

(4) To record the estimated income taxes related to the pro forma adjustments
    referred to in notes (1), (2) and (3) above at an estimated combined U.S.
    federal and state income tax rate of 40%.

(5) Represents the results of operations of the 1998 acquisitions from the
    beginning of fiscal year 1998 through the dates of acquisition with
    adjustments to reflect the amortization of goodwill and other intangible
    amounts together with the related income tax effects at a 40% rate.

(6) The pro forma earnings per share were calculated based on a one for one
    share distribution and equivalent stock options being granted to holders of
    GenCorp stock options.

                         REPORT OF INDEPENDENT AUDITORS

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF GENCORP INC.:

     We have audited the accompanying combined balance sheets of OMNOVA
Solutions Inc. (the Performance Chemicals and Decorative & Building Products
businesses of GenCorp Inc.) as of November 30, 1998 and 1997, and the related
statements of combined income, divisional equity and cash flows for each of the
three years in the period ended November 30, 1998. These financial statements
are the responsibility of GenCorp Inc.'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 combined financial position of OMNOVA Solutions
Inc. at November 30, 1998 and 1997, and the combined results of its operations
and its cash flows for each of the three years in the period ended November 30,
1998, in conformity with generally accepted accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
                        NOVEMBER 30, 1998, 1997 AND 1996

                  INFORMATION AS OF AND FOR THE PERIODS ENDED
                       MAY 31, 1999 AND 1998 IS UNAUDITED

NOTE A -- SIGNIFICANT ACCOUNTING POLICIES

     BASIS OF PRESENTATION -- On December 17, 1998, GenCorp's (Company) Board of
Directors announced a plan to spin off its Performance Chemicals and Decorative
& Building Products businesses (OMNOVA Solutions Inc.) to its shareholders.
These businesses have been operated as divisions of GenCorp and include a
subsidiary operated in the United Kingdom. In the spin-off, each of the
Company's shareholders will receive a pro rata share of the voting common stock
of OMNOVA Solutions Inc. (Omnova Solutions) in a special dividend (Distribution)
and Omnova Solutions will become a separately traded, publicly held company. The
Company has received a ruling from the U.S. Internal Revenue Service (the IRS)
that this transaction will be free from U.S. federal income taxes. The
Distribution is subject to several conditions, including shareholder approval as
well as market conditions at the time of the proposed spin-off.

     The accompanying combined financial statements have been prepared on a
basis which reflects the historical financial statements of Omnova Solutions.
This assumes that the businesses of the Company expected to be contributed to
Omnova Solutions in connection with the Distribution were organized as a
separate legal entity. Generally, only assets and liabilities of the ongoing
Omnova Solutions businesses expected to be transferred to Omnova Solutions prior
to the Distribution were included in the Combined Balance Sheets.

     The Company provides certain general and administrative services to Omnova
Solutions including administration, finance, legal, treasury, information
systems and human resources. The cost for these services was allocated to Omnova
Solutions by the Company based upon a formula that includes sales, gross payroll
and average invested capital. Management of the Company believes that the
allocation of cost for these services is reasonable. These allocations were $12
million, $13 million, and $12 million in 1998, 1997 and 1996, respectively, and
$7 million and $6 million for the six month periods ended May 31, 1999 and 1998,
respectively. After the Distribution, Omnova Solutions will be required to
perform these general and administrative services using its own resources or
purchased services and will be responsible for the costs and expenses associated
with the management of a public company. Omnova Solutions' management estimates
that the costs of such general and administrative expenses on a stand-alone
basis would have been approximately $22 million in 1998.

     As described in Note J, Omnova Solutions' employees and retirees
participate in various Company pension, health care, savings and other benefit
plans. The net expenses related to these plans are included in the Omnova
Solutions combined financial statements generally based on historical pension
asset allocations and actuarial analyses for pension and retiree health care
obligations and based on actual cost for active health care, savings and other
benefit plans.

     The Company uses a centralized approach to cash management and financing
for its domestic operations. As a result, cash and cash equivalents and debt
were not allocated to Omnova Solutions' domestic operations in the historical
financial statements. The cash and cash equivalents included in the Combined
Balance Sheets relate to Omnova Solutions' foreign operations. Omnova Solutions
generally has not had borrowings except amounts due to the Company. Interest
expense has been allocated to Omnova Solutions in the combined financial
statements to reflect Omnova Solutions' pro rata share of the financing
structure of the Company. The allocation in the combined financial statements is
based upon the percentage relationship between the average net assets employed
in Omnova Solutions' operations and the Company's overall average net assets. As
a stand alone entity, Omnova Solutions will establish its own credit facilities.
It is anticipated that as of the date of the Distribution, Omnova Solutions will
borrow an amount and pay the Company a dividend. The actual amount to be
borrowed by Omnova Solutions and paid as a dividend to the Company will be
determined at the time of the Distribution. The actual amount will depend, in
part, on the amount of the borrowings by the Company at that time.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

     The allocation methodology followed in preparing the combined financial
statements may not necessarily reflect the results of operations, cash flows, or
financial position of Omnova Solutions in the future, or what the results would
have been had Omnova Solutions been a separate stand-alone public entity for all
periods presented.

     The Distribution will be accomplished through a distribution agreement that
will provide for, among other things, the assets to be contributed to Omnova
Solutions and the liabilities to be assumed by Omnova Solutions, certain of
which assets and liabilities have not been included in the accompanying Combined
Balance Sheets. Those assets and liabilities include, among other things, a
defined amount of debt and related corporate assets and liabilities.

     The Company and Omnova Solutions will also enter into an employee benefits
and compensation allocation agreement to set forth the manner in which assets
and liabilities under employee benefit plans and other employment related
liabilities will be allocated between them. Certain assets and liabilities
related to the plans have not been included in the accompanying Combined Balance
Sheets. These included, among other things, assets and liabilities for the U.S.
defined benefit pension plans and obligations for health care and other
postretirement benefits that Omnova Solutions is expected to retain for
substantially all of its active and retired U.S. employees.

     The final determination of the assets to be contributed to Omnova Solutions
and the liabilities to be assumed by Omnova Solutions and the dividend to be
paid by Omnova Solutions to the Company will be made pursuant to the agreements
to be entered into between the Company and Omnova Solutions in connection with
the Distribution. As of the date of the Distribution, the net effect of the
final transfer and dividend will be treated as a reduction in "Divisional
Equity" in the Combined Balance Sheets.

     PRINCIPLES OF COMBINATION -- The combined financial statements of Omnova
Solutions include the accounts of the related businesses. Significant
interdivisional accounts and transactions have been eliminated.

     REVENUE RECOGNITION -- Revenue from product sales is recognized when
shipment to the customer has been made, which is when title passes. Omnova
Solutions estimates and records provisions for quantity rebates, sales returns,
allowances and original warranties in the period the sale is recorded, based
upon its experience.

     USE OF ESTIMATES -- The preparation of the combined financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the amounts reported in the combined
financial statements and accompanying notes. Actual results could differ from
those estimates.

     ENVIRONMENTAL COSTS -- Omnova Solutions expenses, on a current basis,
recurring costs associated with managing hazardous substances and pollution in
ongoing operations. Omnova Solutions accrues for costs associated with the
remediation of environmental pollution when it becomes probable that a liability
has been incurred and its proportionate share of the amount can be reasonably
estimated. Omnova Solutions recognizes amounts recoverable from insurance
carriers or other third parties when the collection of such amounts is probable
and estimatable. Accruals are not material.

     FAIR VALUE OF FINANCIAL INSTRUMENTS -- Omnova Solutions' cash equivalents
bear interest at market rates and therefore their carrying values approximate
their fair values.

     INVENTORIES -- Inventories are stated at the lower of cost or market,
primarily using the last-in, first-out method.

     LONG-LIVED ASSETS -- Property, plant and equipment are recorded at cost.
Refurbishment costs are capitalized in the property accounts whereas ordinary
maintenance and repair costs are expensed as incurred. Depreciation is computed
principally using the straight-line method. Depreciable lives on buildings and
improvements, and machinery and equipment, range from 10 to 40 years and 3 to 20
years, respectively.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

     Goodwill represents the excess of the purchase price over the estimated
fair value of the net assets acquired and is amortized on a straight-line basis
over periods ranging from 30 to 40 years. Identifiable intangible assets, such
as patents, trademarks and licenses, are recorded at cost or when acquired as
part of a business combination at their estimated fair value. Identifiable
intangible assets are amortized over their estimated useful lives using the
straight-line method over periods ranging from 3 to 15 years. Accumulated
amortization of goodwill and identifiable intangible assets at November 30, 1998
and 1997 was $4 million and $1 million, respectively.

     Impairment of long-lived assets 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.

     FOREIGN CURRENCY TRANSLATION -- The financial position and results of
operations of Omnova Solutions' foreign subsidiaries are measured using the
local currency as the functional currency. Assets and liabilities of operations
denominated in foreign currencies are translated into U.S. dollars at exchange
rates in effect at year-end, while revenues and expenses are translated at the
weighted average exchange rates prevailing during the year. The resulting
translation gains and losses on assets and liabilities are charged or credited
directly to divisional equity, and are not included in net income until realized
through sale or liquidation of the investment.

     INCOME TAXES -- Omnova Solutions is included in the consolidated returns
filed by GenCorp and its subsidiaries in various U.S. and foreign jurisdictions.
The tax provisions reflected in the Statements of Combined Income have been
computed as if Omnova Solutions was a separate company. The accompanying
Combined Balance Sheets include deferred tax amounts applicable to Omnova
Solutions which result from temporary differences between the carrying amount of
assets and liabilities for financial reporting and income tax purposes. Taxes
currently payable and income tax payments are recorded directly by GenCorp and,
as a result, amounts related to Omnova Solutions are included in "Net
transactions with GenCorp" in the Statements of Combined Cash Flows.

     EARNINGS PER SHARE -- Historical earnings per share have not been presented
as Omnova Solutions was operated as a division of the Company and had no
outstanding stock.

     INTERIM FINANCIAL INFORMATION -- The financial information at May 31, 1999,
and for the six months ended May 31, 1999 and 1998 is unaudited but includes all
adjustments (consisting only of normal recurring adjustments) which Omnova
Solutions considers necessary for a fair presentation of its financial position,
operating results and cash flows. Results of these periods are not necessarily
indicative of results expected for the entire year.

NOTE B -- UNUSUAL ITEMS


     In 1998, Omnova Solutions' Decorative & Building Products segment
recognized unusual expense of $3 million related to exiting the residential
wallcovering business. This business was sold to Blue Mountain Wallcoverings,
Inc. for approximately $9 million on December 14, 1998. Assets disposed of
consisted of equipment and inventory with carrying amounts of $7.9 million and
$1.5 million, respectively. Trademarks and sample books totaling $2.1 million
were written off since they no longer had a use and severance costs of $0.5
million were accrued. The severance costs related to termination benefits to be
paid to 21 employees. The payment of these benefits occurred in the first
quarter of fiscal year 1999.



     In 1996, Omnova Solutions recognized unusual income of $4 million from the
sale of the structural urethane adhesives business.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE C -- NEW ACCOUNTING PRONOUNCEMENTS

     Omnova Solutions adopted Statement of Financial Accounting Standards No.
130, "Reporting Comprehensive Income" (SFAS 130), as of December 1, 1998, which
established standards for reporting and displaying comprehensive income and its
components in the financial statements. The adoption of SFAS 130, which had no
impact on Omnova Solutions' net income or divisional equity, requires
translation adjustments to be included in other comprehensive income.

     In June 1997, the Financial Accounting Standards Board (FASB) issued
Statement No. 131, "Disclosures about Segments of an Enterprise and Related
Information" (SFAS 131). This statement is required to be adopted in fiscal year
1999. SFAS 131 requires that annual and interim financial and descriptive
information about reportable operating segments be reported on the same basis
used internally for evaluating segment performance and the allocation of
resources. While Omnova Solutions has not yet determined the impact of adopting
SFAS 131 on its financial statement disclosures, Omnova Solutions does not
expect any change to its primary financial statements.

     In June 1998, the FASB issued Statement No. 133, "Accounting for Derivative
Instruments and Hedging Activities", which is required to be adopted in fiscal
year 2001. Because of Omnova Solutions' minimal use of derivatives, management
does not anticipate that the adoption of this Statement will have a significant
effect on earnings or the financial position of Omnova Solutions.

     In April 1998, the American Institute of Certified Public Accountants
(AICPA) issued Statement of Position (SOP) 98-5, "Reporting the Costs of
Start-Up Activities" (SOP 98-5). SOP 98-5 is effective beginning on December 1,
1999, and requires that start-up costs capitalized prior to December 1, 1999 be
written off and any future start-up costs be expensed as incurred. Omnova
Solutions has no capitalized start-up costs and therefore, the adoption of SOP
98-5 will not have an effect on the combined financial statements.

     In March 1998, the AICPA issued SOP 98-1, "Accounting For the Costs of
Computer Software Developed For or Obtained For Internal Use" (SOP 98-1). SOP
98-1 is effective for Omnova Solutions beginning on December 1, 1999. SOP 98-1
will require the capitalization of certain costs incurred after the date of
adoption in connection with developing or obtaining software for internal use.
Omnova Solutions believes it is in compliance with the standards established by
SOP 98-1 and as such SOP 98-1 will not impact Omnova Solutions' future earnings
or financial position.

NOTE D -- ACQUISITIONS AND DIVESTITURES

ACQUISITIONS

     On October 29, 1998, Omnova Solutions acquired certain net assets of Sequa
Chemicals, the specialty chemicals unit of Sequa Corporation, for $108 million
in cash. This acquisition provided technology, customers and increased capacity
for an array of emulsion polymers and polymer hybrids including acrylics and
vinyl acetate. The preliminary purchase price allocation resulted in goodwill
and other intangible assets of approximately $61 million which are being
amortized over periods ranging from 5 to 40 years.

     On August 14, 1998, Omnova Solutions acquired the commercial wallcovering
business of Walker Greenbank PLC, which is based in the United Kingdom, for $112
million in cash. The preliminary purchase price allocation resulted in goodwill
and other intangible assets of approximately $80 million which are being
amortized over periods ranging from 5 to 40 years.

     On March 1, 1998, Omnova Solutions acquired The Goodyear Tire & Rubber
Company's Calhoun, Georgia latex facility for an aggregate consideration of $78
million, of which $74 million was paid in cash and $4 million was paid through
the retention of receivables. The acquisition resulted in goodwill and other
intangible assets of $59 million which are being amortized over periods ranging
from 3 to 40 years.

     On May 7, 1997, Omnova Solutions acquired certain net assets of Printworld
from Technographics, Inc. for $47 million in cash. The acquisition resulted in
goodwill and other intangible assets of $32 million which are being amortized
over periods ranging from 3 to 30 years.

     On August 23, 1996, Omnova Solutions purchased the Lytron(R) polystyrene
latex plastic pigment business from Morton International Inc. for approximately
$4 million. The acquisition resulted in intangible assets of $3 million which
are being amortized over 15 years.

     All of the above acquisitions were accounted for using the purchase method
and were included in the results of operations of Omnova Solutions from the
respective dates of acquisition.

     The following unaudited pro forma information presents a summary of the
combined results of operations of Omnova Solutions as if the fiscal 1998
acquisitions had occurred at the beginning of fiscal 1997, with pro forma
adjustments to reflect the amortization of goodwill and other intangible assets
and interest expense on incurred debt together with the related income tax
effects. The pro forma financial information is not necessarily indicative of
the combined results of operations if the acquisitions had actually occurred at
the beginning of fiscal 1997.

NOTE J -- EMPLOYEE BENEFIT PLANS

     In February 1998, the FASB issued Statement No. 132, "Employers'
Disclosures about Pensions and Other Postretirement Benefits" (SFAS 132). SFAS
132 supersedes the disclosure requirements in Statements No. 87, "Employers'
Accounting for Pensions", No. 88, "Accounting for Settlements and Curtailments
of Defined Benefit Pension Plans and for Termination Benefits", and No. 106,
"Employers' Accounting for Postretirement Benefits Other Than Pensions." SFAS
132 addresses disclosure issues only and did not change the measurement or
recognition provisions specified in those Statements.

     PENSION PLANS -- Omnova Solutions participates in a number of GenCorp
sponsored defined benefit pension plans which cover substantially all salaried
and hourly employees. Normal retirement age is generally 65, but certain plan
provisions allow for earlier retirement. The funding policy for the pension
plans is consistent with the funding requirements of federal law. The pension
plans provide for pension benefits, the amounts of which are calculated under
formulas principally based on average earnings and length of service for
salaried employees and under negotiated nonwage based formulas for hourly
employees. The majority of the pension plans' assets are invested in listed
stocks and bonds and short-term investments.

     Pension expense allocated to Omnova Solutions in fiscal 1998, 1997 and 1996
was $6 million, $5 million and $5 million, respectively.

     HEALTH CARE PLANS -- Omnova Solutions also participates in a number of
GenCorp sponsored health care and life insurance programs which cover most
retired employees in the United States. The health care programs generally
provide for cost sharing in the form of contributions, deductibles and
coinsurance between GenCorp and the retirees. Retirees in certain other
countries are provided similar benefits by plans sponsored by their governments.

     Retiree health care expense allocated to Omnova Solutions for 1998, 1997
and 1996 was $3 million, $3 million and $4 million, respectively.

     The projected benefit obligation, accumulated benefit obligation and fair
value of plan assets for the pension plans with accumulated benefit obligations
in excess of plan assets were $14 million, $12 million, and $0, respectively, as
of November 30, 1998, and $12 million, $11 million, and $0, respectively, as of
November 30, 1997.

     For measurement purposes, a 9 percent annual rate of increase in the per
capita cost of retiree health care benefits was assumed for 1999. The rate was
assumed to decrease gradually to 6 percent for 2002 and remain at that level
thereafter.

     Because most employer benefits are capped, assumed health care cost trend
rates have a minimal effect on the amounts reported for the health care plans. A
one-percentage point increase/decrease in assumed health care cost trend rates
would increase/decrease the benefit obligation at November 30, 1998 by $4
million and increase/ decrease the aggregate of the service and interest
components of net periodic cost by $0.3 million.

     Omnova Solutions participates in a number of GenCorp sponsored defined
contribution pension plans. Participation in these plans is available to
substantially all salaried employees and to certain groups of hourly employees.
Contributions to these plans are based on either a percentage of employee
contributions or on a

specified amount per hour based on the provisions of each plan. The cost of
these plans for Omnova Solutions was $2 million in each of 1998 and 1997 and $1
million in 1996.

NOTE K -- LEASE COMMITMENTS

     Omnova Solutions leases certain facilities, machinery and equipment and
office buildings under long-term, noncancelable operating leases. The leases
generally provide for renewal options ranging from five to ten years and require
Omnova Solutions to pay for utilities, insurance, taxes and maintenance. Rent
expense was $4 million in 1998 and $3 million in each of 1997 and 1996. Future
minimum commitments at November 30, 1998 for existing operating leases were $14
million with annual amounts declining from $4 million in 1999 to $1 million in
2003. Omnova Solutions' obligation for leases after 2003 is $1 million.

NOTE L -- CONTINGENCIES

     Omnova Solutions is subject to various legal actions and proceedings
relating to a wide range of matters. In the opinion of management, after
reviewing the information which is currently available with respect to such
matters and consulting with legal counsel, any liability which may ultimately be
incurred with respect to these matters will not materially affect the financial
condition of Omnova Solutions. The effect of resolution of these matters on
results of operations cannot be predicted because any such effect depends on
both future results of operations and the amount and timing of the resolution of
such matters.

NOTE M -- BUSINESS SEGMENT INFORMATION

     Omnova Solutions designs and manufactures performance chemicals and
decorative and building products for industry and consumers. Omnova Solutions is
a leading producer of polymer-based products. Its principal markets include the
paper industry and residential and commercial construction, as well as diverse
consumer and industrial markets that demand a broad range of products and
solutions. No one customer accounts for 10 percent of consolidated sales.

     Segment operating profit represents net sales less applicable costs,
expenses and provisions for restructuring and unusual items relating to
operations. Segment operating profit excludes corporate income and expenses,
interest expense and income taxes.

     In 1998, Decorative & Building Products recognized unusual expense of $3
million related to exiting the residential wallcovering business. In 1996,
Performance Chemicals recognized unusual income of $4 million from the sale of
the structural urethane adhesives business.

     Approximately 28% of Omnova Solutions' employees are covered by collective
bargaining agreements. One of these agreements, covering approximately 22% of
Omnova Solutions' covered employees, will expire within the next 12 months.
Omnova Solutions has not experienced significant work stoppage at any of its
facilities in the past. However, a prolonged work stoppage at any of Omnova
Solutions' facilities could materially adversely affect Omnova Solutions'
business and results of operations.

     Omnova Solutions' operations are located primarily in the United States and
Europe starting in 1998. Inter-area sales are not significant to the total sales
of any geographic area. Unusual items included in operating profit pertained to
United States operations.

NOTE N -- PRO FORMA BALANCE SHEET -- UNAUDITED

     In connection with the Distribution, it is anticipated that Omnova
Solutions will enter into a credit agreement, the terms of which are currently
being negotiated. The credit agreement is expected to provide $300 million of
available credit on a five-year revolving basis. Immediately prior to the
Distribution, Omnova Solutions will borrow approximately $188 million under the
credit agreement. At the same time, Omnova Solutions will declare and distribute
to the Company a special dividend in the amount of approximately $188 million.
Omnova Solutions expects to use funds borrowed under the credit agreement to pay
the special dividend to the Company. Estimated interest expense based on the
anticipated borrowing of $188 million is $5 million for the six months ended May
31, 1999 and $3 million for the year ended November 30, 1998 on a pro forma
basis. The actual amount to be borrowed by Omnova Solutions and distributed to
the Company will be determined at the time of the Distribution.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of
GenCorp Inc.:

     We have audited the accompanying consolidated statements of income, cash
flows and changes in shareholder's equity of Sequa Chemicals Corporation for the
period from January 1, 1998 to October 28, 1998. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audit.

     We conducted our audit 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 audit provides a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, Sequa Chemicals Corporation's results of operations
and cash flows for the period from January 1, 1998 to October 28, 1998, in
conformity with generally accepted accounting principles.

                          SEQUA CHEMICALS CORPORATION

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
            FOR THE PERIOD FROM JANUARY 1, 1998 TO OCTOBER 28, 1998

1.  SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES

BASIS OF PRESENTATION

     Through October 28, 1998, Sequa Chemicals, Inc. ("Sequa Chemicals" or the
"Company") was a wholly owned subsidiary of Sequa Corporation ("Parent"). The
consolidated financial statements of Sequa Chemicals have been prepared on a
stand-alone basis and include the accounts of its majority owned subsidiaries.
Accordingly, certain costs, as discussed in Note 2, incurred by Sequa
Corporation on behalf of the Company have been included in the consolidated
statement of income. Additionally, as discussed in Note 3, the tax provision has
been prepared as if the Company was a stand-alone entity for the period
presented. All intercompany accounts have been eliminated in consolidation.

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

     For purposes of the statement of cash flows, the Company considers time
deposits, certificates of deposit and marketable securities with original
maturities of three months or less when purchased to be cash equivalents.

PROPERTY, PLANT AND EQUIPMENT

     For financial reporting purposes, depreciation and amortization of
property, plant and equipment costs are computed using the straight-line method
over their estimated useful lives which range between 10 and 30 years.
Accelerated depreciation methods are used for income tax purposes.

     The Company reviews properties for impairment whenever events or changes in
circumstances indicate that the carrying value of an asset may not be fully
recoverable. If the estimated future cash flows expected to result from the use
of an asset and its eventual disposition are less than the carrying amount of
the asset, then the property is written down to its fair market value.

     Upon sale or retirement of properties, the related costs and accumulated
depreciation are removed from the accounts, and any gain or loss is reflected
currently. For the period from January 1, 1998 to October 28, 1998, total
depreciation expense was $2,789,527.

GOODWILL AND OTHER INTANGIBLES

     Excess of cost over net assets of companies acquired (goodwill) is being
amortized on a straight-line basis over periods not exceeding forty years. The
recoverability of goodwill is evaluated at the operating unit level by an
analysis of operating results and consideration of other significant events or
changes in the business environment. If an operating unit has current operating
losses, and based upon projections there is a likelihood that such operating
losses will continue, the Company evaluates whether impairment exists on the
basis of undiscounted expected future cash flows from operations before interest
during the remaining amortization period. If impairment exists, the carrying
amount of the goodwill is reduced to market value.

     The Company has also acquired patents and trademarks related to certain
manufacturing related processes. Such patents and trademarks are being amortized
over a period of eleven years.

     Amortization expense related to goodwill and other intangibles for the
period from January 1, 1998 to October 28, 1998 was $872,566.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

FOREIGN CURRENCY TRANSLATION

     The financial position and results of operations of the Company's foreign
subsidiaries are measured using local currency as the functional currency.
Assets and liabilities of operations denominated in foreign currencies are
translated into U.S. dollars at exchange rates in effect at year-end, while
revenues and expenses are translated at weighted average exchange rates
prevailing during the year. The resulting translation gains and losses on assets
and liabilities are charged or credited directly to cumulative translation
adjustment, a component of shareholder's equity, and are not included in net
income until realized through sale or liquidation of the investment.

ENVIRONMENTAL REMEDIATION AND COMPLIANCE

     It is the Company's policy to accrue environmental remediation costs for
identified sites when it is probable that a liability has been incurred and the
amount of loss can be reasonably estimated. Accrued environmental remediation
and compliance costs include remedial investigation and feasibility studies,
outside legal, consulting and remediation project management fees, projected
cost of remediation activities, site closure and post-remediation monitoring
costs. For the period from January 1, 1998 to October 28, 1998, the total amount
charged to selling, general and administrative expense for environmental and
remediation compliance efforts was approximately $3,000,000.

REVENUE RECOGNITION

     Sales are recorded when title passes to the customer, which is when
products are shipped.

RESEARCH AND DEVELOPMENT

     Research and development costs are charged to expense as incurred.

COMPREHENSIVE INCOME

     Effective January 1, 1998, Sequa Chemicals adopted Statement of Financial
Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive Income." This
statement establishes standards for the reporting of comprehensive income and
its components in financial statements. Comprehensive income consists of net
income and other gains and losses affecting shareholder's equity that, under
generally accepted accounting principles, are excluded from net income. For
Sequa Chemicals, these items consist of foreign currency translation
adjustments. The adoption of SFAS No. 130 did not have a material effect on
Sequa Chemical's primary financial statements, but did affect the presentation
of the accompanying consolidated statement of changes in shareholder's equity.

SEGMENT INFORMATION

     Sequa Chemicals adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information." Sequa Chemicals has only one segment,
Chemicals, and accordingly no additional segment information has been provided.

2.  TRANSACTIONS WITH PARENT

     The Company participates in various corporate programs administered by
Sequa Corporation. Expenses representing the cost to operate Sequa Chemicals on
a stand-alone basis have been included in the accompanying consolidated
statement of income. Such costs include the following:

<TABLE>
<S>                                                           <C>
Selling, general and administrative expenses................  $1,170,963
401(k) expenses.............................................   1,011,296
Insurance expenses..........................................   1,763,708
EPA costs...................................................   3,000,000
Interest expense on average debt............................   1,474,264
                                                              ----------
Total corporate expense.....................................  $8,420,231
                                                              ==========
</TABLE>

     Specifically identifiable costs related to 401(k) expenses, Insurance
expenses and EPA costs, as noted above, have been included in the consolidated
statement of income.

     Selling, general and administrative expenses have been allocated to the
Company based on a three-factor formula that considers average payroll costs,
sales and assets. Interest expense is allocated to the Company based on the
average assets employed for the period, which approximated $59 million.
Management of the Company believes that the allocation method used for these
costs is reasonable.

     There were no other material related party transactions for the period.

3.  INCOME TAXES

     Income taxes are recognized during the year in which transactions enter
into the determination of financial statement income, with deferred taxes being
provided for temporary differences between amounts of assets and liabilities
recorded for tax and financial reporting purposes. The income tax provision
included in the consolidated statement of income has been prepared as if Sequa
Chemicals was a stand-alone entity for the period from January 1, 1998 to
October 28, 1998.

     The income tax provision for the period from January 1, 1998 to October 28,
1998, consisted of:

<TABLE>
<S>                                                           <C>
United States federal
  Current...................................................  $ 828,959
  Deferred..................................................   (700,216)
State and local.............................................     77,506
                                                              ---------
                                                              $ 206,249
                                                              =========
</TABLE>

     The income tax provision is different from the amount computed by applying
the U.S. federal statutory income tax rate of 35% to income before income taxes.
The reasons for this difference for the period from January 1, 1998 to October
28, 1998, are as follows:

<TABLE>
<S>                                                           <C>
Computed income taxes at statutory rate.....................  $115,398
State and local taxes, net of federal income tax benefit....    50,379
Meals and entertainment.....................................    40,472
                                                              --------
                                                              $206,249
                                                              ========
</TABLE>

     No provision has been made for U.S. or additional foreign taxes on
undistributed earnings of foreign subsidiaries as those earnings are intended to
be permanently reinvested. Such earnings would become taxable upon the sale or
liquidation of these foreign subsidiaries or upon the remittance of dividends.

4.  SUBSEQUENT EVENT

     On October 29, 1998, Sequa Corporation sold the net operating assets of
Sequa Chemicals to GenCorp Inc. for approximately $108 million in cash.

                   EUROPEAN COMMERCIAL WALLCOVERINGS BUSINESS

                         REPORT OF INDEPENDENT AUDITORS

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF GENCORP INC.

     In our opinion, the accompanying combined profit and loss account, combined
statement of total recognised gains and losses and combined statement of cash
flows present fairly, in all material respects, the combined profit and combined
cash flows of the European Commercial Wallcoverings Business for the years ended
January 31, 1998 and January 31, 1997 in conformity with accounting principles
generally accepted in the United Kingdom. These financial statements are the
responsibility of the management of the European Commercial Wallcoverings
Business; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these statements in
accordance with auditing standards generally accepted in the United Kingdom
which are substantially the same as auditing standards generally accepted in the
United States. 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, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

     Accounting principles generally accepted in the United Kingdom vary in
certain significant respects from accounting principles generally accepted in
the United States. The application of the latter would have affected the
determination of combined profit expressed in pounds sterling for both of the
two years in the period ended January 31, 1998 to the extent summarised in note
12 to the combined financial statements.

                   EUROPEAN COMMERCIAL WALLCOVERINGS BUSINESS

                   NOTES TO THE COMBINED FINANCIAL STATEMENTS

  INFORMATION FOR THE 6 MONTH PERIODS ENDED JULY 31, 1998 AND JULY 31, 1997 IS
                                   UNAUDITED.

1.  BASIS OF PREPARATION

     The combined financial statements reflect the combined operations of
Brymor, Muraspec, Muraspec Belgium and Muraspec SARL, which together formed the
commercial wallcoverings business ("the European Commercial Wallcoverings
Business") purchased by GenCorp Inc. in a transaction completed on August 13,
1998. Brymor, Muraspec and Muraspec Belgium were operating divisions within the
Walker Greenbank PLC group whilst Muraspec SARL was a wholly-owned subsidiary
whose ultimate parent company was Walker Greenbank PLC.

     The combined financial statements comprise a combined profit and loss
account, a combined statement of total recognised gains and losses and a
combined statement of cash flows, together with related accounting policies and
footnotes, for the European Commercial Wallcoverings Business. The combined
financial statements cover the years ended January 31, 1998 and January 31, 1997
and the six month periods ended July 31, 1998 and July 31, 1997.

     No balance sheets are presented in these combined financial statements.
Accounting policies in respect of balance sheet items are included only in
respect of their relevance to the reconciliation of movement in shareholders'
funds.

     The information presented for the years ended January 31, 1998 and January
31, 1997 is audited ("Audited Combined Financial Statements"). Information for
the 6 month periods ended July 31, 1998 and July 31, 1997 is unaudited
("Unaudited Combined Financial Statements").

     The accompanying unaudited combined profit and loss account and cash flows
for the six months ended July 31, 1998 and July 31, 1997 have been prepared on
the same basis as the Audited Combined Financial Statements and, in the opinion
of management, include all adjustments necessary to present fairly the financial
information set forth therein.

     During the periods included in these combined financial statements the
European Commercial Wallcoverings Business did not constitute a separate group
or company; however, for the purpose of this presentation, Brymor, Muraspec,
Muraspec Belgium and Muraspec SARL were each accounted for on a stand-alone
basis. In view of the historical structure of the European Commercial
Wallcoverings Business a separate combination of the individual entities has
been prepared for the financial statement periods presented in these financial
statements. These financial statements are the responsibility of GenCorp Inc.

     The combined financial statements are based on an aggregation of the
results of Brymor, Muraspec, Muraspec Belgium and Muraspec SARL. Transactions
and balances between these four elements have been eliminated on aggregation.
The combined profit and loss account of the European Commercial Wallcoverings
Business include all material revenues and expenses that would have been
incurred had the European Commercial Wallcoverings Business operated on a
stand-alone basis.

     The financial statements have been prepared in all material respects in
accordance with Generally Accepted Accounting Principles in the UK ("UK GAAP")
and are expressed in pounds sterling ("GBP").

INTEREST

     The European Commercial Wallcoverings Business has participated in cash
sweep arrangements operated by Walker Greenbank PLC, whereby certain cash
balances have been cleared periodically to central accounts held by Walker
Greenbank PLC. Similarly, to the extent that the European Commercial
Wallcoverings Business has had short-term borrowing requirements it has borrowed
from Walker Greenbank PLC. No interest has generally been received or charged in
respect of balances with Walker Greenbank PLC.

            NOTES TO THE COMBINED FINANCIAL STATEMENTS--(CONTINUED)

  INFORMATION FOR THE 6 MONTH PERIODS ENDED JULY 31, 1998 AND JULY 31, 1997 IS
                                   UNAUDITED.

TAXATION

     During the periods included in these combined financial statements only
Muraspec SARL constituted a separate company for taxation purposes. Brymor,
Muraspec and Muraspec Belgium were operating divisions within Walker Greenbank
PLC. For the purposes of these combined financial statements, separate
corporation and deferred tax calculations have been prepared as if the three
operating divisions had been stand-alone companies. The assumption has been made
that any tax liabilities arising that were not paid by the European Commercial
Wallcoverings Business were settled by Walker Greenbank PLC as a capital
contribution to the European Commercial Wallcoverings business.

GROUP MANAGEMENT CHARGES

     During the periods covered by these combined financial statements, the
European Commercial Wallcoverings Business received charges for head office
services carried out, or costs incurred on its behalf, by Walker Greenbank PLC.
These management charges were allocated between the businesses making up the
Walker Greenbank PLC group on bases that Walker Greenbank PLC management
determined to be reasonable. These bases have varied during the periods covered
by those combined financial statements.

     It is possible that the level of cost incurred for such services would have
been different had the European Commercial Wallcoverings Business existed as a
stand-alone entity during those periods.

PENSIONS

     During the periods covered by these combined financial statements certain
employees of the European Commercial Wallcoverings Business were members of
either one of two separate defined benefit group pension schemes operated by
Walker Greenbank PLC. Separate actuarial calculations have been performed to
determine an appropriate pensions charge for these employees under UK generally
accepted accounting practice.

SUBSEQUENT EVENTS

     No account has been taken of changes in accounting policy, estimates or
judgement arising directly from the acquisition by GenCorp Inc. on August 13,
1998.

2.  ACCOUNTING POLICIES

     The principal accounting policies are set out below.

ACCOUNTING CONVENTION

     The financial statements are prepared under the historical cost convention
modified for the revaluation of certain properties and in accordance with
applicable accounting standards.

PATTERN BOOKS AND SHADE CARDS

     The cost of pattern books and shade cards for ranges launched in the year
is charged directly to the profit and loss account.

     Costs incurred in developing pattern books and shade cards for ranges not
yet launched are held within work in progress in stocks and are written off in
the year of launch. Pattern books and shade cards held for resale are included
in finished goods at the lower of cost and net realisable value.

                   EUROPEAN COMMERCIAL WALLCOVERINGS BUSINESS

            NOTES TO THE COMBINED FINANCIAL STATEMENTS--(CONTINUED)

  INFORMATION FOR THE 6 MONTH PERIODS ENDED JULY 31, 1998 AND JULY 31, 1997 IS
                                   UNAUDITED.

FOREIGN CURRENCY

     Monetary assets and liabilities denominated in foreign currencies are
translated at the rate of exchange ruling at the balance sheet date.
Transactions in foreign currencies are recorded at the rate ruling at the date
of the transaction or, if hedged, at the forward contract rate.

     The balance sheets of overseas entities are translated at the rates of
exchange ruling at the balance sheet date. The profit and loss accounts are
translated at the average rates of exchange applicable to the accounting period.

TURNOVER

     The group turnover represents the invoiced value, excluding VAT, of sales
to external customers.

STOCKS

     Stocks and work in progress are stated at the lower of cost and net
realisable value. Cost comprises direct materials, on a first-in, first-out
basis, and direct labour plus attributable production overheads based on a
normal level of activity. Net realisable value is based on estimated selling
prices less anticipated costs to disposal.

PENSIONS

     The cost of providing retirement pensions and related benefits is charged
to the profit and loss account over the periods during which members are
employed. Any surplus of assets over liabilities is apportioned over the
expected remaining service lives of current employees in the schemes.

RESEARCH AND DEVELOPMENT

     Costs incurred in setting up production lines for new product ranges are
capitalised and amortised over the expected lives of those ranges. Other
research and development expenditure is written off as incurred.

FIXED ASSETS

     Depreciation is charged on a straight-line basis on the original cost or
subsequent valuation of assets (excluding freehold land) after deduction of any
estimated residual value.

     The principal annual rates are:

<TABLE>
<S>                              <C>
Freehold Buildings               2%
Short and Long Leaseholds        Over the unexpired period of lease
Plant, Equipment and Vehicles    Between 5% and 33%
</TABLE>

     Land and buildings are stated at cost plus any revaluation reserve less
provision for permanent diminution in value.

     The direct costs of developing computer software for internal use are
capitalised as part of fixed assets within the category of Plant, Equipment and
Vehicles.

LEASING AND HIRE PURCHASE COMMITMENTS

     Rentals paid under operating leases are charged to income as incurred.

that they are expected to reverse in the foreseeable future, calculated at the
rate at which it is estimated that tax will be payable.

8.  PENSION COSTS

     Qualifying employees of the European Commercial Wallcoverings Business were
members of one of two defined benefit pension schemes operated by Walker
Greenbank PLC during the periods covered by these financial statements. The
assets of the schemes are held in separate trustee administered funds.

     The pension costs are assessed in accordance with the advice of an
independent qualified actuary using the projected unit method. These schemes are
subjected to triennial actuarial reviews with the most recent ones having been
at 6 April 1996 for the major scheme and 6 April 1995 for the Abaris Holdings
Limited Pension Scheme (formerly Warner Fabrics Scheme).

                                   UNAUDITED.

     The principal actuarial assumptions applied for the two schemes were as
follows:

<TABLE>
<S>                   <C>
Investment returns    9.0% per annum
Salary growth         7.0% per annum
Pension increases     5.0% per annum in excess of Guaranteed Minimum Pension
</TABLE>

     Assets have been valued using the discounted income method assuming a
dividend growth rate of 4.5% per annum.

     At the latest actuarial valuation, the aggregate market value of the assets
of the major scheme was L22,173,000. The actuarial value of the assets of the
scheme was sufficient to cover 106% of the liability for benefits which have
accrued to members on an ongoing basis.

     At the last actuarial valuation, the aggregate market value of the assets
of the Abaris Holdings Limited Pension scheme (formerly Warner Fabrics Scheme)
was L2,423,000. The actuarial value of the assets of the scheme was sufficient
to cover 205% of the liability for benefits which have accrued to members on an
ongoing basis.

12.  DESCRIPTION OF SIGNIFICANT DIFFERENCES BETWEEN UK GAAP AND US GAAP

     The combined financial statements are prepared in accordance with generally
accepted accounting principles in the United Kingdom ("UK GAAP"), which differ
in certain respects from generally accepted accounting principles in the United
States ("US GAAP").

     The principal differences between UK GAAP and US GAAP are presented below
together with explanations of certain adjustments that affect consolidated net
income and total shareholders' equity as of and for the years ended January 31,
1998 and January 31, 1997 and for the six month periods ended July 31, 1998 and
July 31, 1997:

(1) CAPITALISED PRODUCT AND COMPUTER SOFTWARE DEVELOPMENT COSTS

     The European Commercial Wallcoverings Business has a policy of capitalising
certain development costs in respect of new product ranges and computer software
development costs. These development costs are amortised over a three year
period. Under US GAAP, such development costs are expensed as incurred.

(2) REVALUATION OF PROPERTY AND EQUIPMENT

     Under UK GAAP, companies are permitted to perform revaluations of property
on a periodic basis and adjust the carrying values to the revalued fair market
value. The related depreciation is calculated on the revalued amounts where
applicable. Any surplus or deficit on the revaluation of property and equipment
is taken directly to a revaluation reserve, which is part of shareholders'
funds.

     Under US GAAP, such revaluations are not permitted and depreciation is
provided on the original cost of property and equipment.

(3) PENSIONS

     Under UK GAAP, an actuarial valuation method must be used to determine
annual pension cost. The valuation is normally performed every three years. The
benefit obligation is discounted at a long term risk adjusted rate and the plan
assets are valued on an actuarial basis. The expected cost of pensions is
charged to the profit and loss account so as to spread the variation from the
regular cost over the expected remaining service lives of employees.

     Under US GAAP, annual actuarial valuations must be carried out for defined
benefit pension obligations. The present value of the benefit obligation is
determined using a current market discount rate such as that of a high quality,
fixed rate debt instrument and the plan assets are valued on a market or market
related basis. Actuarial gains and losses that arise within a prescribed
"corridor" do not have to be amortised. Actuarial gains and losses outside the
corridor are amortised over the average expected remaining service of employees.

     The principal actuarial assumptions for the two Walker Greenbank PLC UK
pension plans under SFAS Nos. 87 and 132 are as follows:

(8) CONSOLIDATED STATEMENT OF CASH FLOWS

     The Company's consolidated cash flow statement is prepared in accordance
with UK Financial Reporting Standard No 1 "Cash Flow Statements" and presents
substantially the same information as that required under US GAAP. However,
there are certain differences in classification of items within the cash flow
statement and with regard to the definition of cash and cash equivalents between
UK and US GAAP.

     Under UK GAAP cash flows represent increases or decreases in cash, which is
comprised of cash in hand and deposits repayable on demand less overdrafts. Cash
flows are presented in the following categories (i) operating activities (ii)
returns on investments and servicing of finance (iii) taxation (iv) capital
expenditure and financial investment (v) acquisitions and disposals (vi) equity
dividends paid (vii) management of liquid resource and (viii) financing
activities.

     Under US GAAP cash flows represent increases or decreases in cash and cash
equivalents, which include short term highly liquid investments with original
maturities of less than 90 days and exclude overdrafts. Cash flows are reported
in only three categories of operating activities, investing activities and
financing activities.

     Cash flows from taxation and returns on investments and servicing of
finance are operating activities under US GAAP. The payment of dividends and
debt issue costs are included under financing activities. Capitalised interest
is included under investing activities for US GAAP purposes.

     Cash flows from capital expenditure and financial investment as well as
cash flows from acquisitions and disposals are included as investing activities
under US GAAP. Cash flows from the management of liquid resources are included
in the overall cash movement since liquid resources are considered cash
equivalents under US GAAP.

     Cash, for purposes of the cash flow under UK GAAP, includes bank overdrafts
but excludes liquid resources. Under US GAAP bank overdrafts are considered
loans and the movements thereon are included in financing activities. Liquid
resources are considered cash equivalents and the movements thereon are included
in the overall cash movement.

confirmation, novation or approval (a "Consent") of a third party, would
constitute a breach or other contravention thereof, be ineffective or in any way

                                       12

and such Interest had been transferred to OMNOVA; and (ii) enforce, at the
request of OMNOVA, any rights of GenCorp arising from such Interest against the
issuer thereof or the other party or parties thereto (including the right to
elect to terminate any such Interest in accordance with the terms thereof with
the consent of OMNOVA). Nothing in this Section 2.07 shall be deemed a waiver by
OMNOVA of its right to receive at the Closing Time an effective Transfer of all
of the Contributed Assets nor shall this Section 2.07 be deemed to constitute an
agreement to exclude any asset, property or right from the Contributed Assets.

similar requirements, or (iii) to comply with its obligations under this
Agreement or any Ancillary Agreement; provided, however, that in the event that
any party determines that any such provision of Information could be
commercially detrimental, violate any law or agreement, or waive any
attorney-client privilege, the parties shall take all reasonable measures to
permit the compliance with such obligations in a manner that avoids any such
harm or consequence.

                  (b) Any Information owned by GenCorp or OMNOVA that is
provided to a requesting party pursuant to this Section 4.06 shall be deemed to
remain the property of the providing party. Unless specifically set forth
herein, nothing contained in this Agreement shall be construed as granting or
conferring rights of license or otherwise in any such Information.

                  (c) Except as otherwise agreed, the party requesting such
Information agrees to reimburse the other party for the reasonable out-of-pocket
costs, if any, of creating, gathering and copying such Information, to the
extent that such costs are incurred for the


                                       16
<PAGE>   20

benefit of the requesting party.

                  (d) The parties agree to use their reasonable efforts to
retain all Information in their respective possession or control on the
Distribution Date for a period of six years or such longer period as required by
any applicable legal requirement and, with respect to the Information pertaining
to Taxes, until the expiration of the applicable statute of limitations or as
otherwise required by a Legal Requirement. No party will destroy or dispose of,
or permit any member of its Group to destroy or disposal of, any Information
which the other party may have the right to obtain pursuant to this Agreement
prior to the sixth anniversary of the date hereof or the expiration of any such
statute of limitations without first using its reasonable efforts to notify the
other party of the proposed destruction or disposal and giving the other party
the opportunity to take possession of such Information in lieu of such
destruction.

                  (e) The rights and obligations granted under this Section 4.06
are subject to any specific limitations, qualifications or additional provisions
regarding the sharing, exchange or confidential treatment of Information set
forth in any Ancillary Agreement.

         Section 4.07. WITNESS SERVICES. At all times from and after the
Distribution Date, each of GenCorp and OMNOVA shall use its reasonable efforts
to make available to the other party's Group, upon reasonable written request,
the officers, directors, employees and agents of the members of its Group for
the fact finding, consultation or interviews and as witnesses to the extent that
such persons may reasonably be required in connection with the prosecution or
defense of any action in which the requesting party or any member of its Group
may from time to time be involved. Except as otherwise agreed, a party providing
such services to any other party under this Section 4.07 shall be entitled to
reimbursement from the recipient of such services upon the presentation of
invoices therefor, for reasonable out-of-pocket costs and expenses incurred in
connection with providing such services.

         Section 4.08. CONFIDENTIALITY. Each of GenCorp and OMNOVA, on behalf of
itself and each member of its Group, agrees to hold, and to cause its respective
directors, officers, employees and agents to hold, in strict confidence, all
Information concerning the other Group furnished by any such other Group or its
respective directors, officers, employees or agents, at any time pursuant to
this Agreement, any Ancillary Agreement or otherwise, and shall not use any such
Information other than for such purposes as shall be expressly permitted
hereunder or thereunder, except, in each case, to the extent that such
Information has been (a) is in or later enters the public domain through no
fault of such party or any member of its Group or any of their respective
directors, officers, employees or agents, (b) later lawfully acquired from other
sources by such party (or any member of such party's Group) which sources are
not themselves bound by a confidentiality obligation, or (c) independently
generated without reference to any proprietary or confidential Information of
the other party. Each party agrees not to release or disclose, or permit to be
released or disclosed, any such Information to any other Person, except its
directors, officers, employees and agents who need to know such Information (who
shall be advised of their obligations hereunder with respect to such


                                       17
<PAGE>   21

Information). Without limiting the foregoing, when any Information is no longer
needed for the purposes contemplated by this Agreement or any Ancillary
Agreement, each party will promptly after request of the other party either
return to the other party all Information in a tangible or electronic form
(including all copies thereof and all notes, extracts or summaries based
thereon) or certify to the other party that it has destroyed such Information
(and such copies thereof and such notes, extracts or summaries based thereon).
Notwithstanding the immediately two preceding sentences, in the event that a
member of a Group either determines on the advice of its counsel that it is
required to disclose any Information pursuant to applicable law or receives any
demand under lawful process or from any Governmental Authority to disclose or
provide Information of the other party (or any Group member of the other party)
that is subject to the confidentiality provisions hereof, such party shall
notify the other party prior to disclosing or providing such Information and
shall cooperate at the expense of the requesting party in seeking any reasonable
protective arrangements requested by such other party. Subject to the foregoing,
the Person that received such request may thereafter disclose or provide
Information to the extent required by such law (as so advised by counsel) or by
lawful process or such Governmental Authority.

         Section 4.09. CERTAIN TAX MATTERS. (a) Neither the GenCorp Group nor
the OMNOVA Group shall take any action inconsistent with, nor fail to take any
action described in the Ruling Request or the Ruling, unless such Party (the
"Proposing Party") has obtained the prior written consent of the other Party
(the "Non-Proposing Party") which consent shall not be unreasonably withheld.
The Non-Proposing Party shall grant its consent to an action proposed by the
Proposing Party if the Proposing Party either (i) obtains a ruling with respect
to the proposed action from the IRS or other applicable Tax Authority that is
reasonably satisfactory, in form and substance, to the Non-Proposing Party and
its tax counsel (except that the Proposing Party shall not submit any ruling
request for the purpose of complying with this Section 4.09 if the Non-Proposing
Party reasonably determines that filing such request might adversely affect the
Non-Proposing Party), or (ii) obtains an opinion from tax counsel reasonably
satisfactory to the Non-Proposing Party (both as to choice of counsel and the
opinion given). Each of the Parties covenants that it will cooperate in
connection with any future submissions to the IRS in connection with the Ruling
Request and the Ruling, and will certify to the extent it can do so, upon
reasonable request, that the factual statements, representations and other
similar conditions contained therein are true, correct and complete in all
material respects. Each of the Parties represents that neither it nor any of its
Affiliates has any plan or intention to take any action which is inconsistent
with any factual statements, representations or other similar conditions
contained in the Ruling Request or in the Ruling.

                  (b) ACTIVE BUSINESS; CONTINUITY OF BUSINESS ENTERPRISE.
GenCorp and OMNOVA each represents that it has no plan or intent to reduce,
eliminate or otherwise discontinue the businesses relied upon in the Ruling
Request. GenCorp and OMNOVA each will not take any action which might result in
a substantial contraction or elimination of such businesses (for purposes of
Section 355(b) of the Code and the "continuity of business enterprise"
requirement for tax-free distributions under Section 355 of the Code) within the




                                       18
<PAGE>   22

five year period beginning on the Distribution Date, without the prior written
consent of the other party which consent shall not be unreasonably withheld.

                  (c) CHANGE IN CONTROL. GenCorp and OMNOVA each represents
that, apart from the Spin-off, it has no plan or intention to engage in any
transaction or transactions having the effect of a change in the ownership or
50% or more of its outstanding stock (by vote or value), within the meaning of
Section 355(e) of the Code.

         Section 4.10.  INSURANCE MATTERS.

                  (a) With respect to any Losses suffered by OMNOVA relating to,
resulting from or arising out of any events or occurrences on or prior to the
Distribution Date (including, without limitation, in respect of the conduct of
the OMNOVA Business or the ownership or operation of the Additional Assets) for
which GenCorp, any GenCorp Entity or any OMNOVA Entity would be entitled to
assert, or cause any other Person to assert, a claim for recovery under any
policy of insurance maintained by or for the benefit of GenCorp, any GenCorp
Entity or any OMNOVA Entity (excluding insurance included in the Contributed
Assets) (collectively, "GenCorp Insurance"), at the request of OMNOVA, GenCorp
will, in good faith, promptly assert and diligently prosecute one or more claims
under the GenCorp Insurance; provided that all of GenCorp's and any GenCorp
Entities reasonable out-of-pocket costs and expenses incurred in connection with
asserting and prosecuting such claim shall be promptly reimbursed by OMNOVA
(including, without limitation, costs and expenses resulting from any
deductible, policy limit, self-insurance retention, or retroactive or
retrospective premium). To the extent required under the terms of the GenCorp
Insurance to give effect to this Section 4.10, GenCorp will be deemed, solely
for the purpose of asserting claims under the GenCorp Insurance pursuant to the
immediately preceding sentence to have assumed or retained liability for such
Loss to the extent of the policy limits of the applicable policy of GenCorp
Insurance. GenCorp shall not release, disseminate, commute or otherwise
terminate (collectively,"Terminate") any policy of GenCorp Insurance unless: (i)
GenCorp gives OMNOVA reasonable advance written notice of its intent to do so
(which notice shall describe in reasonable detail the policy to be Terminated
and the terms of the Termination sought to be entered into by GenCorp or any
GenCorp Entity), (ii) GenCorp agrees in writing with OMNOVA to assume any and
all liability that the insurer would have had in respect of any Loss which has
or may be suffered by OMNOVA which but for such Termination would have been
covered by the Terminated policy, and (iii) GenCorp provides OMNOVA with
reasonable assurances of its ability to satisfy its obligations under (ii)
above.

                  (b) Each of GenCorp and OMNOVA shall acquire and maintain in
force for a period of three years (the "Initial Period") after the Distribution
Date directors and officers insurance coverage equivalent to the directors and
officers insurance coverage in force on the Distribution Date. If at any time
and for any reason during the six years following the Initial Period a member of
the GenCorp Group or OMNOVA Group decides to terminate or chooses not to renew
its directors and officers insurance coverage in force at the end of the Initial



                                       19
<PAGE>   23

Period, then the member deciding to terminate or choosing not to renew such
coverage shall, at its expense, convert any such policy to a run-off policy that
shall remain in force for not less than six years after the conversion date.

                  (c) With respect to aircraft products produced by GenCorp
prior to the date hereof, GenCorp will include and maintain OMNOVA as an insured
under any Aircraft Products Liability Policy of GenCorp in force as of the date
hereof or hereafter obtained. GenCorp will give OMNOVA reasonable advance
written notice if GenCorp ceases to maintain Aircraft Product Liability
insurance which is substantially similar to the insurance in force as of the
date hereof.

                           ARTICLE V: INDEMNIFICATION
                           ---------  ---------------

         Section 5.01. INDEMNIFICATION BY GENCORP. Subject to Section 5.03,
GenCorp shall indemnify, defend and hold harmless OMNOVA, each OMNOVA Entity and
each of their respective directors, officers, employees and agents, and each of
the heirs, successors and assigns of any of the foregoing (the "OMNOVA
Indemnitees") from and against all Losses arising out of, associated with, or
resulting from:

                  (a) any failure to perform or breach of any covenant or
agreement made by GenCorp in this Agreement or in any Ancillary Agreement;

                  (b) any failure to pay, perform or otherwise promptly
discharge any Retained Liability; or

                  (c) any Spin-Off Taxes excluding any Spin-Off Taxes described
in Section 5.02(c).

         Section 5.02. INDEMNIFICATION BY OMNOVA. Subject to Section 5.03,
OMNOVA shall indemnify, defend and hold harmless GenCorp, each GenCorp Entity
and each of their respective directors, officers, employees and agents, and each
of the heirs, successors and assigns of any of the foregoing (the "GenCorp
Indemnitees") from and against all Losses arising out of, associated with, or
resulting from:

                  (a) any failure to perform or breach of any covenant or
agreement made by OMNOVA in this Agreement or in any Ancillary Agreement
delivered by OMNOVA;

                  (b) any failure to pay, perform or otherwise promptly
discharge any Assumed Liability; or

                  (c) any Spin-Off Taxes resulting from any member of the OMNOVA
Group or any employee, officer or director of such member acting in his or her
capacity as such, taking or failing to take any action following the Spin-Off
(including any actions specified in



                                       20
<PAGE>   24

Section 4.09) or any change in ownership of OMNOVA stock whether or not OMNOVA
has acted or failed to act in connection with such change, to the extent that
such action or failure to act causes the Spin-Off to fail to qualify as fully
tax-free under Sections 368(a)(1)(D), 355, and 361, or any other provisions of
the Code.

         Section 5.03. THIRD PARTY CLAIM PROCEDURES. If a party receives notice
of the assertion of any Third Party Claim in respect of which such party may
have a claim under Section 5.01 or 5.02 then the following shall apply:

                  (a) The party against whom any such Third Party Claim is made
(the "Indemnified Party"), shall promptly provide written notice (an "Indemnity
Notice") of such Third Party Claim to the other party (the "Indemnifying
Party"). Such Indemnity Notice shall describe in reasonable detail the nature of
the Third Party Claim and the basis for its claim under Section 5.01 or 5.02;
provided that the failure to provide such notice shall not affect a party's
rights under Section 5.01 or 5.02 except to the extent the other party is
actually prejudiced by the failure to give such notice and then only to the
extent of such actual prejudice. An Indemnity Notice by a party shall not
preclude such party from giving subsequent Indemnity Notices with respect to
other claims, whether arising before or after the claims for which prior notice
is given.

                  (b) Upon receipt of an Indemnity Notice, the Indemnifying
Party shall have the right to promptly assume, at its sole cost and expense, the
defense or settlement of such Third Party Claim with counsel reasonably
acceptable to the Indemnified Party, provided that the Indemnifying Party has
irrevocably agreed in writing to defend, indemnify and hold harmless the
Indemnified Party in respect of all Losses arising or resulting from such Third
Party Claim. The Indemnifying Party shall give prompt written notice to the
Indemnified Party of its intent to enter into such agreement and assume the
defense of any such Third Party Claim and shall conduct the defense and/or
settlement of such Third Party Claim diligently and in good faith. If the
Indemnifying Party enters into such agreement and assumes such defense then for
so long as the Indemnifying Party is defending such Third Party Claim in
accordance with its obligations hereunder then the Indemnified Party shall not
admit any liability with respect to, or settle, any said Third Party Claim
without the Indemnifying Party's prior written consent; provided, however, that
the Indemnified Party shall have the right to settle, compromise or discharge
such Third Party Claim without the consent of the Indemnifying Party if the
Indemnified Party releases the Indemnifying Party from its indemnification
obligation hereunder with respect to such Third Party Claim. If requested by the
Indemnifying Party, the Indemnified Party shall cooperate fully in the defense
or prosecution of any Third Party Claim the defense of which has been assumed by
the Indemnifying Party, and the Indemnified Party shall furnish such records,
information and testimony and attend all such conferences, discovery
proceedings, hearings, trials and appeals as may be reasonably requested in
connection therewith, but the Indemnifying Party will reimburse the Indemnified
Party for any reasonable out-of-pocket fees or expenses incurred by it in so
cooperating or acting at the request of the Indemnifying Party.



                                       21
<PAGE>   25

                  (c) Notwithstanding Section 5.02(b), if (i) an Indemnified
Party is obligated to permit an insurer or other Person having liability
therefore to assume the defense of a Third Party Claim, or (ii) an Indemnified
Party determines in good faith that there is a reasonable possibility that a
Third Party Claim may materially and adversely affect it or its assets or
business other than as a result of the payment of monetary damages, or (iii) the
Indemnifying Party and Indemnified Party are both named parties in a Third Party
Claim and in the reasonable judgment of the Indemnified Party a conflict of
interest (other than a dispute regarding the scope of the Indemnified Party's
right to indemnification under this Agreement) between the Indemnified Party and
the Indemnifying Party exists or (iv) if the Indemnifying Party fails, after
reasonable notice from the Indemnified Party, to diligently and in good faith
defend such Third Party Claim, then, at the option of the Indemnified Party, the
Indemnifying Party shall not have the right to assume the defense of such Third
Party Claim and the Indemnified Party may, by notice to the Indemnifying Party,
reassume the defense of any such Third Party Claim previously assumed by the
Indemnifying Party. No retention or reassumption of any such defense by the
Indemnified Party shall prejudice any rights of the Indemnified Party under
Section 5.01 or 5.02.

                  (d) If the Indemnifying Party does not give notice and assume
the defense of such Third Party Claim in accordance with Section 5.03(b) or is
not entitled to assume or retain the defense thereof, the Indemnified Party
shall have full authority to defend and/or settle any such Third Party Claim for
the account of and at the sole risk, cost and expense of the Indemnifying Party.
If the Indemnified Party undertakes the defense and/or settlement of any such
Third Party Claim it shall do so diligently and in good faith and the
Indemnifying Party shall from time to time upon the request of the Indemnified
Party reimburse the Indemnified Party for the costs incurred by the Indemnified
Party in defending and/or settling such Third Party Claim. The Indemnifying
Party shall be bound by any settlement entered into by the Indemnified Party to
the extent that such settlement is commercially reasonable measured in the
context of the matter settled and by any judgment resulting from such Third
Party Claim. If the Indemnifying Party had the right to assume the defense and
settlement of such Third Party Claim and did not do so then, in any dispute
between the Indemnifying Party and Indemnified Party regarding the defense or
settlement of such Third Party Claim the Indemnifying Party shall have the
burden to prove that the Indemnified Party did not defend such Third Party Claim
diligently and in good faith and/or settle such claim in a commercially
reasonable manner.

                  (e) Notwithstanding any provision of this Agreement or any
Ancillary Agreement the parties agree that if any right of the Indemnified Party
would be irreparably and irredeemably prejudiced by its failure to join the
Indemnifying Party in any legal proceeding brought by a third party asserting a
Third Party Claim, then the Indemnified Party may join the Indemnifying Party in
such legal proceeding brought by the third party asserting such Third Party
Claim as to which any right under Section 5.01 or 5.02 would or might apply, for
the purpose of enforcing any such right.



                                       22
<PAGE>   26

                  (f) The Indemnifying Party shall not admit any liability,
settle, compromise, pay or discharge, without the consent of the Indemnified
Party, any Third Party Claim being defended by it unless with respect to any
settlement (i) the Indemnified Party is not obligated to perform or to refrain
from performing any act under such settlement and there is no encumbrance on any
assets of the Indemnified Party; (ii) there is no finding or admission of any
violation of any Legal Requirement, violation of the rights of any Person by the
Indemnified Party or any other liability or obligation of the Indemnified Party
to any Person; and (iii) the Indemnified Party receives, as a part of such
settlement, a complete release, in form and substance reasonably satisfactory to
the Indemnified Party.

                  (g) The party controlling the defense of a Third Party Claim
shall keep the other party reasonably informed at all stages of the defense
and/or settlement of such Third Party Claim. The party not controlling the
defense of any such Third Party Claim shall have the right, at its sole cost and
expense, to participate in, but not control, the defense of any such Third Party
Claim.

         Section 5.04. LIMITATIONS IN INDEMNIFICATION OBLIGATIONS. The amount
that an Indemnifying Party is or may be required to pay to an Indemnified Party
pursuant to Section 5.01 or 5.02 shall be reduced by any Insurance Proceeds or
other amounts actually recovered by or on behalf of such Indemnified Party, in
reduction of the related Loss. If an Indemnified Party shall have received the
payment required by this Agreement from an Indemnifying Party in respect of any
Loss and shall subsequently actually receive Insurance Proceeds or other amounts
in respect of such Loss, then such Indemnified Party shall pay to such
Indemnifying Party a sum equal to the amount of such Insurance Proceeds or other
amounts actually received (up to but not in excess of the amount of any
indemnity payment made hereunder). No insurer or other Person shall: (a) be
relieved of the responsibility to pay any claims which it would otherwise be
obligated to pay in the absence of the foregoing indemnification provisions; (b)
solely by virtue of the indemnification provisions hereof, have any subrogation
rights with respect to any claims which it would otherwise be obligated to pay
or (c) be entitled to a benefit it would not be entitled to receive in the
absence of the foregoing indemnification provisions.

         Section 5.05. PRIMARY POLICY. Any insurance policy of any
Indemnified Party shall be deemed to be primary to any obligation of an
Indemnified Party under this Agreement.

collectively, the "Spin-off"); and

transactions required to effect the Spin-off, together with the terms of such
transactions and related matters, in a Distribution Agreement between GenCorp

         WHEREAS, after the Spin-off. OMNOVA and its Affiliates will cease to be

the allocation of liabilities for Taxes with respect to the Parties prior to,
arising out of, and subsequent to the Spin-off, (2) the preparation and filing
of Tax Returns along with the payment of Taxes shown due and payable thereon,
(3) the retention and maintenance of records necessary to prepare and file
appropriate Tax Returns and to handle any Tax Contests, as well as the provision
for appropriate access to those records by the Parties, (4) the conduct of
audits, examinations and proceedings by governmental entities which could result
in a redetermination of Taxes of the Parties, (5) the responsibility for any Tax
deficiencies and the treatment of refunds of Taxes and Carryovers and Carrybacks
of the Parties, (6) the cooperation of the Parties with one another in order to

         2.05 METHOD OF ALLOCATING TAXES FOR STRADDLE PERIODS.

                  (a)    To the extent required or allowed by applicable law,
the Parties shall apportion their respective liabilities for Taxes relating to a
Straddle Period that begins before and ends after the Distribution Date in
accordance with an actual or hypothetical closing of the books on the
Distribution Date in the case of income Taxes or other Taxes based on actual
events and activities of such Party.

                  (b)    Except as provided in Section 2.05(a), Taxes for any
Straddle Period, with respect to any member of the GenCorp Group and the OMNOVA
Group shall be apportioned between Pre-Distribution and Post-Distribution
Periods as follows: First, Taxes for Tax Periods or portions thereof ending on
the last day of the calendar month preceding the Distribution Date (such date is
hereinafter referred to as the "Cutoff Date") shall be based on actual events
and activities through the Cutoff Date and in accordance with past accounting
practices. Second, Taxes for the period from the Cutoff Date through the
Distribution Date shall be computed by prorating the activities of the calendar
month which includes the Distribution Date on a daily pro rata basis.
Notwithstanding the foregoing provisions of this Section 2.05(b), (i)
depreciation, amortization and depletion for any Straddle Period shall be
apportioned on a daily pro rata basis and (ii) extraordinary items not arising
in the ordinary course of business shall be apportioned to the Tax Period in
which the event giving rise to such item occurs.

                  (c)    For purposes of this Agreement, franchise Taxes shall
be allocated to the Periods in which the items with respect to which the Tax is
imposed occur, regardless of whether the Tax is imposed with respect to one or
more other Periods.

<PAGE>   11

                  (d) For purposes of this Agreement, any taxes computed on a
unitary method shall be allocated between the members of the GenCorp
Group and the OMNOVA Group consistent with past accounting practice and
consistent with applicable law.

         2.06 TAX ACCOUNTING PRACTICES. Any Straddle Period Returns prepared by
any member of the GenCorp Group or the OMNOVA Group shall be filed in accordance
with past Tax accounting practices used with respect to the Tax Returns in
question, and to the extent any items are not covered by past practices, in
accordance with reasonable Tax accounting practices selected by GenCorp or
OMNOVA, as the case may be (except that accounting elections and determinations
shall be made by each Party, where reasonably possible, in a manner that
minimizes the net Tax incurred by the other Party and its Affiliates). In the
event any member of the GenCorp Group or the OMNOVA Group files Tax Returns for
Straddle Periods that are inconsistent with such past Tax accounting practices,
then, notwithstanding any provision of this Agreement to the contrary, in
addition to any other remedies available, the other Party shall only be
responsible for the amount of Taxes it would owe if such Tax Returns had been
consistent with such past Tax accounting practices. The Parties shall consult
regarding any such proposed changes in accounting methods and attempt in good
faith to agree as to procedures to be followed and the amount of any indemnity
hereunder.

State Tax Returns relating to income Taxes to be filed under this provision and
the Person responsible for filing each such Return. Without limiting the
foregoing, in accordance with Article VI, the Person responsible for filing such
a Return shall also be responsible for responding to any revenue agent request

         3.02 CONSOLIDATED, COMBINED AND JOINT RETURNS.

                  (a) Any Tax Returns for United States Federal Taxes imposed
for any Pre-Distribution Period which reflect Taxes for which any member of the
GenCorp Group has liability under Article II (including, without limitation,

furtherance of, and not by limitation of, the cooperation and assistance
required by the terms of the Distribution Agreement, OMNOVA shall, in
connection with any Tax Return for United States Federal income Taxes for any

Federal income Tax liability for the OMNOVA Group; (ii) a true and correct

hereunder.

                  (b)    With respect to the Period ending on November 30,
1999, or, where applicable to any Group member, the corresponding 52-53 week
Period (the "1999 Fiscal Year"), OMNOVA hereby agrees to provide GenCorp with
all such Returns, work papers and computations relating to Federal Taxes on or
before May 15, 2000, and with all such Returns, work papers and computations
relating to State Taxes on or before on or before June 15, 2000.

                  (c)    If, without reasonable cause, OMNOVA fails to provide
any information required by this Section 3.02 within the time frame specified
herein, GenCorp may file the applicable Returns based on the information
available at the time such Returns are due and OMNOVA shall be liable for, and
shall indemnify GenCorp from, any interest or penalties relating to Taxes,
additions to Tax or other costs imposed on GenCorp as a result of OMNOVA's
failure to provide such information; provided, however, that in no event will
OMNOVA be liable to reimburse GenCorp for or indemnify GenCorp against any
increase in tax liability (excluding interest, penalties, additions to tax and
the like) resulting from such information. The Parties shall attempt in good
faith to reach agreement regarding the information to be provided by OMNOVA to
GenCorp and the time such information is needed.

                  (d)    Any Tax Returns for State Taxes for any
Pre-Distribution Period which reflect Taxes for which the GenCorp Group has
liability under Article II, shall be prepared and filed by GenCorp. Sections
3.02(a) and 3.02(c) shall apply mutatis mutandis to all State Tax Returns for
any Pre-Distribution Period that GenCorp must prepare and/or file under this
Agreement that is measured by income and that includes any income or
transactions attributable to OMNOVA or any member of the OMNOVA Group.

                  (e)    Any Tax Returns for Foreign Taxes for any
Pre-Distribution Period which reflect Taxes for which the GenCorp Group has
liability under Article II, shall be prepared and filed by GenCorp. Any Tax
Returns for Foreign Taxes for any Post-Distribution Period (including any such
Straddle Period) which reflect Taxes for which the OMNOVA Group has liability
under Article II, shall be prepared and filed by OMNOVA. For any Straddle Period
Tax Returns prepared and filed by OMNOVA, the liability for Taxes reflected on
such Tax Return will be divided between the Pre-Distribution Period and the
Post-Distribution Period in accordance with Section 2.05.

         3.03 RIGHT TO REVIEW RETURNS. Upon the request of either Party, the
other Party shall make available for inspection and copying all Tax Returns (and
related work papers) with respect to Taxes to the extent that (i) such Return
relates to Taxes for which the requesting Party may be liable under this
Agreement, (ii) such Return relates to Taxes for which the requesting Party may
have a claim for Tax Benefits hereunder, or (iii) the requesting Party
reasonably determines that it must inspect such Return to confirm any Person's
compliance with the terms

of this Agreement. The Parties shall attempt in good faith to resolve any issues
arising out of the review of such Returns.

                           TAX REFUNDS AND CARRYOVERS
                           --------------------------

         4.01 REFUNDS. Except as provided in Section 4.02, any refund of any
Taxes for any Pre-Distribution Period shall belong to GenCorp. In the event
OMNOVA or any of its Affiliates receives a refund for any Pre-Distribution
Period, the Person receiving such refund shall immediately remit such refund to
GenCorp. A refund includes the application of an amount otherwise refundable as
a reduction of amounts owed or to be owed notwithstanding that no cash is
transferred.

         4.02 CARRYBACKS OR CLAIMS FOR REFUND.

                  (a)    At the request of OMNOVA and at OMNOVA's expense,
GenCorp or one of its Affiliates will file one or more claims for refund
(including any tentative carryback or refund adjustment under Section 6411 of
the Code) of Taxes with respect to any Pre-Distribution Period resulting from
any Carryback generated by any member of the OMNOVA Group from a
Post-Distribution Period ("OMNOVA Group Carryback"), provided (subject to
Section 4.02(b)) that such refund does not result in any increase in the
liability of any member of GenCorp's Group for Taxes for any Tax Period. In the
event GenCorp or one of its Affiliates receives a refund for any
Pre-Distribution Period resulting from any OMNOVA Group Carryback from a
Post-Distribution Period, GenCorp shall immediately remit such refund to OMNOVA.

                  (b)    In the event GenCorp or one of its Affiliates files
one or more claims for refund (including any tentative carryback or refund
adjustment under Section 6411 of the Code) of Taxes with respect to any
Pre-Distribution Period resulting from any OMNOVA Group Carryback from a
Post-Distribution Period that results in any increase in the liability of any
member of GenCorp's Group for Taxes for any Tax Period, GenCorp or any of its
Affiliates shall be entitled to retain that portion of the refund that exactly
offsets the additional Taxes for which it becomes liable as a result of filing
the refund claim, and the balance of such refund shall be refunded immediately
to OMNOVA. To the extent the increased liability for Taxes of GenCorp or any of
its Affiliates with respect to any Pre-Distribution Period resulting from any
OMNOVA Group Carryback from a Post-Distribution Period is reversed for any Tax
Period, the amount of any Tax Benefit resulting from such reversal shall be paid
immediately to OMNOVA on the date when the Return is filed for the year in which
the Tax Benefit arises or, if such return has already been filed, then
immediately after GenCorp or any of its Affiliates receives a payment reflecting
the Tax Benefit in question. Similarly, to the extent the increased liability
for Taxes of GenCorp or any of its Affiliates with respect to any
Pre-Distribution Period resulting from any OMNOVA Group Carryback from a
Post-Distribution Period for any Period arises after the refund has been paid to
OMNOVA, GenCorp shall inform OMNOVA of the amount of such increase, and OMNOVA
shall pay the amount of such increase to GenCorp promptly. Procedures similar to
those in Section 5.03 shall apply. All computations under this Section 4.02


                                       10

shall be adjusted to take into account interest payable by or to GenCorp, and
any Tax Benefit resulting therefrom.

         4.03 CARRYOVERS FROM PRE-DISTRIBUTION PERIODS TO POST-DISTRIBUTION
              PERIODS.

                  (a)    If GenCorp or any of its Affiliates (determined for
this purpose as of immediately before the Distribution Date) is entitled to
carry over any Tax Benefit from a Pre-Distribution Period to a Post-Distribution
Period, and if the proper person to claim such Tax Benefit is a member of the
OMNOVA Group, OMNOVA or such member shall, upon request of GenCorp and at
GenCorp's expense, file any return or report reasonably requested by GenCorp in
a manner that claims such Tax Benefit and shall pay the full amount of such Tax
Benefit to GenCorp promptly upon receipt, provided (subject to Section 4.03(b))
that such Tax Benefit does not result in any increase in the liability of any
member of the OMNOVA Group for Taxes for any Tax Period.

                  (b)    If OMNOVA or any of its Affiliates claims a carryover
of a Tax Benefit described in Section 4.03(a) that results in any increase in
the liability of any member of the OMNOVA Group for Taxes for any Tax Period,
the provisions of Section 4.02(b) shall apply, mutatis mutandis, to OMNOVA's
obligation to refund such Tax Benefit to GenCorp.

         4.04 STATE TAX CREDITS. Notwithstanding any other provision of this
Agreement, the Parties shall consult and shall attempt in good faith to agree
concerning the allocation between them of credits for State Taxes.

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

         5.01 PAYMENT OF CONSOLIDATED UNITED STATES FEDERAL TAXES FOR
PRE-DISTRIBUTION PERIODS. GenCorp shall pay all Taxes due, be entitled to the
benefit of all overpayments of estimated income tax, and, except as provided in
Section 4.02, shall receive all refunds in connection with, the filing of
GenCorp's Tax Returns relating to U.S. Federal Taxes for all Pre-Distribution
Periods, including GenCorp's consolidated Federal income Tax Return for the 1999
Fiscal Year.

         5.02 PAYMENT OF STATE AND FOREIGN TAXES FOR WHICH GENCORP HAS FILING
RESPONSIBILITY. GenCorp shall pay to the appropriate Tax Authority all State and
Foreign Taxes for Tax Returns with respect to which GenCorp (or another member
of the GenCorp Group) has filing responsibility pursuant to Article III.

         5.03 INDEMNIFICATION PAYMENTS.

                  (a)    The Parties shall attempt to agree upon procedures
for the payment of indemnities under this Agreement. In the absence of any such
Agreement, the procedures set forth in paragraph (b) shall be followed.

                  (b)    Upon payment of any Taxes with respect to which
either Party is entitled to receive indemnification hereunder, such member (the
"Indemnified Party") shall send to the other Party (the "Indemnifying Party") an
invoice accompanied by evidence of payment and a statement detailing the Taxes
paid and describing in reasonable detail the particulars relating thereto. The
Indemnifying Party (or such one or more members of the Indemnifying Party's
Group as it shall nominate) shall remit payment for Taxes for which the
Indemnifying Party is liable for indemnification hereunder to the Indemnified
Party (or such one or more members of the Indemnified Party's Group as it shall
nominate) within 30 days of receipt of such invoice, evidence of payment and
statement, or at any earlier time identified by the Indemnifying Party.
Notwithstanding any provision in this Agreement to the contrary, to the extent
the Indemnified Party receives a refund of Taxes for which it has been
indemnified, it shall remit the refund to the Indemnifying Party (or such one or
more members of the Indemnifying Party's Group as it shall nominate)
immediately. The amount of any payment under this Section 5.03 that is
attributable to interest paid to a Tax Authority shall be adjusted to take into
account the Tax Benefit resulting therefrom.

         5.04 TAX TREATMENT OF TAX AND INDEMNIFICATION PAYMENTS. The Parties
agree that, in the absence of any change in law, any Tax or indemnification
payments made under this Agreement or the Distribution Agreement (including
payments made under Sections 2.04, 4.01, 4.02, 4.03, and 5.03) shall be reported
for Tax purposes by the payor and the recipient as capital contributions or
dividends, as appropriate, relating back to the period beginning before the
Distribution Date. The Parties will file their respective Tax Returns on this
basis, unless agreed otherwise in writing by the Indemnified Party and the
Indemnifying Party.

                                   ARTICLE VI
                                   ----------
                             TAX AUDITS AND APPEALS
                             ----------------------

         6.01 NOTICE. Each Party shall provide prompt notice to the other
Party of any pending or threatened Tax Contest of which it becomes aware
relating to Taxes for Tax Periods for which it is indemnified by the other
Party. Such notice shall contain factual information (to the extent known)
describing any asserted Tax liability in reasonable detail and shall be
accompanied by copies of any notice or other document received from any Tax
Authority in respect of any such matter. If either Party has knowledge of an
asserted Tax liability with respect to a matter for which it is to be
indemnified hereunder and such Party fails to give the Indemnifying Party notice
of such asserted Tax liability within 30 days after it has received written
notice thereof, then, unless such failure has no material adverse effect upon
the Indemnifying Party's ability to participate in the Tax Contest, the
Indemnifying Party shall have no obligation to indemnify the Indemnified Party
for any Taxes arising out of such asserted Tax liability.

         6.02 CONTROL OF AUDITS AND APPEALS.

                  (a)    SEPARATE  CONTESTS.  Any  Separate  Contest  shall be
controlled  solely  by the  Party involved in the Tax Contest.



                                       12
<PAGE>   16

                  (b)    JOINT CONTESTS. With respect to any Joint Contest,
the Party that filed the Return shall control the proceeding. The personnel and
outside advisers (including counsel) of the Party not controlling the proceeding
may participate, at the expense of such Party, in the proceeding to the extent
such proceeding relates to items or adjustments for which such Party may incur
indemnity liability under this Agreement. Such participation shall be reflected
by the grant of appropriate powers of attorney. The Party granting such power of
attorney (the "Granting Party") shall have the right to revoke the power of
attorney if the Granting Party reasonably determines that the actions or failure
to act on the part of the other Person (the "Participating Party") in the
proceeding has resulted, or can be reasonably expected to result, in the
hindrance or delay of any resolution or settlement of the proceeding. In the
event the Participating Party fails to participate timely and fully in any
proceeding to the extent to which such proceeding relates to items or
adjustments for which the Participating Party has indemnity liability under this
Agreement, the Participating Party shall be liable for, in addition to all Taxes
for which the Participating Party shall be liable under this Agreement, any and
all costs imposed on, or incurred by, the Granting Party as a result of the
Participating Party's failure to participate. The revocation of any power of
attorney under this Section 6.02 shall in no way limit the Participating Party's
indemnity liability under this Agreement.

         6.03     CONSENT TO SETTLEMENTS.

                  (a)    Subject to Sections 6.03(b) and (c), neither Party
shall agree to any Tax liability or compromise any Tax claim in a Joint Contest
for the account of any member of the other Group without the consent of such
other Party, which consent shall not be withheld unreasonably. Decisions
regarding settlement of a Joint Contest shall be made jointly by the Parties and
their respective representatives.

                  (b)    If GenCorp refuses to accept a settlement proposal in
a Joint Contest that OMNOVA wishes to accept, then the contest shall continue,
and (i) OMNOVA's liability to GenCorp with respect to such adjustment shall be
determined as if the settlement proposal had been accepted; (ii) GenCorp shall
indemnify OMNOVA from and against any Taxes resulting from an outcome of the
contest less favorable than the settlement and any other costs resulting from
the continuation of the contest, and (iii) GenCorp shall be entitled to all
benefits resulting from any outcome of the contest that is more favorable than
the settlement (less any costs to OMNOVA, against which GenCorp shall indemnify
OMNOVA).

                  (c)    If OMNOVA refuses to accept a settlement proposal in
a Joint Contest that GenCorp wishes to accept, then the contest shall continue
and (i) GenCorp's liability to OMNOVA with respect to such adjustment shall be
determined as if the settlement proposal had been accepted, (ii) OMNOVA shall
indemnify GenCorp from and against any Taxes resulting from an outcome of the
contest less favorable than the settlement and any other costs resulting from
the continuation of the contest, and (iii) OMNOVA shall be entitled to all
benefits resulting from any outcome of the contest that is more favorable than
the settlement (less any costs to GenCorp, against which OMNOVA shall indemnify
GenCorp).

         6.04 INFORMATION. Each Party shall provide the other Party with
information pertaining to any increase or decrease in its Taxes that might
affect the liability for Taxes of the other Party for any Period. In addition,
upon reasonable request, each Party shall provide information to the other Party
regarding the Tax treatment of any item.

         6.05 EXPENSES. Each Party shall bear its own Group's  expenses
incurred in  connection  with any Tax Contest.

         6.06 ADVERSE EFFECT ISSUES

                  (a)    The procedures set forth in Sections 6.06(c) through
6.06(f) shall apply if -

                         (i)    in an  examination  of a Federal income Tax
Return of one of the Parties or any member of its Group (the "Examined Party"),
the IRS raises one or more Adverse Effect Issues, or

                         (ii)   the Examined Party (whether or not in the
course of any audit, examination or other proceeding relating to the
determination of its liability for Federal income Taxes) files an amended
Federal income Tax Return or claim for refund of Federal income Taxes or
otherwise takes a position with the IRS inconsistent with a Federal income Tax
Return already filed, if such amended Federal income Tax Return, claim or
position is likely, itself or in combination with other issues, to be an Adverse
Effect Issue.

                  (b)    One or more issues are "Adverse Effect Issues" if, in
the reasonable judgment of the Examined Party, the aggregate effect of all such
issues with respect to the Periods within an examination cycle or similar
proceeding of the Examined Party is significantly likely to increase the
liability for Federal income Taxes (less interest) of the Party that is not the
Examined Party and the members of its Group (the "Affected Party") by at least
$250,000. Only for purposes of determining whether an issue is an Adverse Effect
Issue, the amount of such increase in liability for Federal income Taxes shall
be measured under the following principles:

                        (i)    All increases (less any offsetting decreases
resulting from the same or a related item) in the Affected Party's liability for
Federal income Tax likely to result from such Adverse Effect Issue for all
Periods shall be taken into account, provided, however, that any decrease in
liability for Federal income Tax that may result from the sale or disposition of
property not expected to be sold or disposed of (for example, stock of an
operating subsidiary), or similar items, shall not be taken into account.

                        (ii)   Computations  of liability for Federal income Tax
shall be based on the highest marginal rate of Federal income Tax applicable to
the Affected Party for each of the Periods involved.

                        (iii)  There shall be taken into  account  only
increases in liability for Federal income Tax as compared with the return
position taken by the Affected Party.



                                       14
<PAGE>   18

                  (c)    In each case,  the Parties shall use their  reasonable
best efforts to identify issues that are, or in combination with other issues
could become, Adverse Effect Issues.

                         (i)    Promptly upon becoming aware that any
Adverse Effect Issue has been raised as described in Section 6.06(a)(i), the
Examined Party shall provide notice of such event to the Affected Party. Such
notice shall include a description of the Adverse Effect Issue, a computation
(as described in Section 6.06(b)(ii)) showing the expected increase in the
Affected Party's liability for Federal income Tax resulting therefrom, and
copies of all correspondence between the Examined Party and the IRS (including
information document requests, responses thereto and notices of proposed
adjustment).

                        (ii)   No less than 30 days before filing any
amended return or claim for refund or taking any action described in Section
6.06(a)(ii), the Examined Party shall (x) provide notice to the Affected Party
(such Notice to include the information and material listed with respect to the
notice provided in Section 6.06(c)(i) and copies of all amended returns, claims
for refund or other documents proposed to be filed with the IRS with respect to
such Adverse Effect Issue) and (y) consult with the Affected Party regarding
such action.

                  (d)    Within 30 days after the notice provided in Section
6.06(c)(i) or Section 6.06(c)(ii), the Affected Party may notify the Examined
Party that the Affected Party wishes to participate in proceedings relating to
the disposition of any or all of the Adverse Effect Issues. If the Affected
Party provides such notice, the procedures for Joint Contest set forth in
Section 6.02(b) shall apply, with the Examined Party being in control of the
proceeding. Provided, however, that (i) if the Affected Party does not provide
such notice within such time period, the proceeding shall continue without
participation of the Affected Party and without regard to Sections 6.06(e) and
6.06(f), and (ii) the Affected Party's right to participate in the proceedings
shall terminate if the Examined Party makes a reasonable determination, after
consultation with the Affected Party, that, notwithstanding the Adverse Effect
Items, the total net increase in the Affected Party's liability for Taxes
(determined as set forth in Section 6.06(b)) from all adjustments relating to
the Period or Periods in the examination cycle or similar proceeding is less
than the amount set forth in Section 6.06(b).

                  (e)    Subject to Section 6.06(f), the Examined Party shall
settle any Adverse Effect Issue with the IRS only with the prior consent of the
Affected Party. The Parties shall attempt in good faith to agree as to the terms
of a proposed settlement. If the Parties are unable to agree, the procedures set
forth in Section 6.03(b) or Section 6.03(c), as the case may be, shall apply to
such Adverse Effect Issue.

                  (f)    Notwithstanding Section 6.06(e), the Examined Party
may settle with the IRS any Adverse Effect Issue without consent of the Affected
Party, if, after consultation with the Affected Party, the Examined Party
reasonably determines that (i) a settlement of such Adverse Effect Issue is
desirable to the Examined Party; (ii) in light of all the circumstances
(including the likelihood of various positions of the Parties being sustained in
further proceedings, the cost of such proceedings and the impact of settlement
on other issues), the overall terms of the settlement do not discriminate
against the Affected Party; and (iii) other


                                       15
<PAGE>   19

issues (which may or may not be Adverse Effect Issues) will be settled, and it
is not practical to settle such other issues on the proposed terms without a
settlement of the Adverse Effect Issue. Before determining that a proposed
settlement of other issues is not practical without a settlement of the Adverse
Effect Issue, the Examined Party will use its reasonable best efforts to secure
a settlement of the other issues while leaving the Adverse Effect Issue open for
further proceedings (for example, by entering into an agreement on IRS Form
870AD or similar form to close proceedings relating to one or more Periods but
reserving the Adverse Effect Issue for further proceedings).

                                   ARTICLE VII
                                   -----------

("GSI"), and (b) any liability to GSI or to any member of the GenCorp Group for
adjustments to State Taxes resulting from transactions or arrangements between
GSI and any other member of the GenCorp Group or the OMNOVA Group. Such
liabilities for any Straddle Year in jurisdictions using the unitary method
shall be determined in accordance with Section 2.05(d).

         7.02 GSI TAX RETURNS.Notwithstanding Sections 3.01 and 3.02, OMNOVA
shall file all State Tax Returns for GSI, with the exception of unitary returns
set forth on Schedule 3.01, and any tax audit or other proceeding pertaining to

shall provide notice to OMNOVA of any issue raised by a Tax Authority that could
reasonably result in the application of this Article VIII.

                                  ARTICLE VIII

         8.01 AMENDMENT AND WAIVER. This Agreement shall not be amended or
modified in any manner whatsoever except by a writing executed by each of the
Parties. No failure by either Party to insist upon the strict performance of any
covenant, duty, agreement or condition of this Agreement or to exercise any
right or remedy consequent upon a breach thereof shall constitute waiver of any
such breach or any other covenant, duty, agreement or condition.

         8.02 TAX ALLOCATION AGREEMENTS, ETC. Immediately prior to the
Distribution, GenCorp shall cause any and all tax allocation, tax sharing and
similar agreements or arrangements existing between GenCorp and all members of
the OMNOVA Group to be terminated as of the Distribution Date, and shall cause
any amounts due under such agreements or arrangements to be settled in the
manner agreed to by the Parties prior to the Distribution Date. Upon such
termination and settlement, no further payments made by one Party to the other
with respect to such agreements or arrangements shall be made, and all other
rights and obligations resulting from such agreements or arrangements between
the Parties shall cease as of such time. This Agreement shall supercede any such
agreements or arrangements.

(including all actions taken in furtherance of said Distribution).

         NOW, THEREFORE, in consideration of the mutual agreements, provisions

         ESCALATION NOTICE: a written notice demanding a meeting of the
         respective Chief Executive Officers of the parties for the purpose of
         resolving a Dispute.

         REQUEST: a written request for mediation under Article III of this
         Agreement which shall set forth the nature of the Dispute and the
         Amount in Controversy.

         TRANSACTION DOCUMENTS: the Distribution Agreement together with the
         Ancillary Agreements and other documents referenced in the Distribution
         Agreement.

                                   ARTICLE II
                             RESOLUTION OF DISPUTES

         Section 2.01. INTENT. It is the intent of the parties to use their
respective reasonable efforts to resolve expeditiously and on a mutually
acceptable negotiated basis any Dispute between them that may arise from time to
time.

         Section 2.02. WAIVER OF RIGHTS. The procedures in this Agreement shall
be the sole and exclusive remedy in connection with any Dispute. Each party to
this Agreement hereby irrevocably waives any rights it may have to trial by jury
or to commence any action in any court of law or equity or before any other
governmental authority with respect to any Dispute, except as expressly
otherwise provided in Sections 4.05(b) and 4.06 of Article IV of this Agreement.

         Section 2.03. PROCEDURE. All Disputes between the parties should be
resolved promptly through consultation and good faith negotiation at the working
levels of GenCorp and OMNOVA. All Disputes which cannot be resolved by the
parties at the working level shall first be subjected to escalation as provided
in Section 2.04 of this Article. If escalation does not resolve the Dispute, the
Dispute shall next be submitted to mediation pursuant to Article III of this
Agreement. If a Dispute cannot be resolved through mediation, then such Dispute
shall be submitted to binding Arbitration pursuant to Article IV of this
Agreement.

         Section 2.04. ESCALATION. If the parties are unable to resolve a
Dispute at working levels within GenCorp and OMNOVA, either party may deliver an
Escalation Notice to the other party demanding an in-person meeting for the
purpose of resolving the Dispute between the Chief Executive Officers ("CEOs")
of both parties in Denver, Colorado, within thirty days of receipt of the
Escalation Notice. The Escalation Notice shall be delivered in accordance with
Section 5.04 of Article V of this Agreement. The CEO's of the parties shall have
fifteen days following their meeting to resolve the Dispute. If the Dispute is
not resolved within the foregoing period, and in any event after forty-five days
following receipt of an Escalation



                                     -2-
<PAGE>   3

Notice, either party may initiate mediation of the Dispute in accordance with
Article III of this Agreement.

                                   ARTICLE III
                                    MEDIATION

         Section 3.01. REQUEST FOR MEDIATION. Following completion of the
escalation procedure described in Section 2.04 of Article II of this Agreement,
either party may initiate mediation by delivering a Request to the other party
in accordance with Section 5.04 of Article V of this Agreement.

         Section 3.02. APPOINTMENT OF MEDIATOR. Unless the parties otherwise
agree in writing, a single mediator will be appointed by the two parties from
among the former directors of GenCorp who ceased to be members of the GenCorp
Board of Directors at least six months before the Distribution. In the event the
parties are unable to agree upon a mediator or no such former director is
available, the parties shall apply to CPR to appoint a single mediator from the
CPR Panel of Neutrals, which appointment shall be made by CPR within 15 days
after such application.

         Section 3.03. DATE, TIME AND PLACE. The date, time and place of each
mediation session shall be determined by agreement of the parties or, if the
parties cannot agree within a reasonable period of time, by the mediator;
provided that the first mediation session shall be held within fifteen (15) days
of the date on which the mediator is appointed. Unless the parties otherwise
agree in writing, all mediation proceedings shall take place in Denver,
Colorado.

         Section 3.04. ROLE OF THE MEDIATOR. The mediator shall aid the parties
in their discussions and negotiations by informally advising the parties. Any
opinion expressed by the mediator shall be strictly advisory and shall not be
binding on the parties; provided, however, any final, written opinion expressed
by the mediator shall be admissible in any arbitration proceedings.

         Section 3.05. COSTS OF MEDIATION. Costs of the mediation shall be borne
equally by the parties, except that each party shall be responsible for its own
attorney's fees and expenses.

         Section 3.06. TERMINATION. The mediation proceedings shall be
terminated upon the happening of any of the following: (i) execution of a
settlement agreement by the parties; (ii) receipt of a written declaration of
the mediator that further efforts at mediation are no longer worthwhile; or,
(iii) receipt of a written declaration of one or both parties that the mediation
proceedings are terminated, which is delivered (in accordance with Section 5.04
of Article V of this Agreement) not earlier than completion of the first
mediation session.

                                   ARTICLE IV
                                   ARBITRATION

         Section 4.01. DEMAND FOR ARBITRATION. (a) At any time after the
termination of mediation as described in Section 3.06 of Article III of this
Agreement, any party may, unless the Applicable Deadline has occurred, make a
Demand that the Dispute be resolved by binding arbitration, which Demand shall
be delivered in the manner set forth in Section 5.04 of Article V of this
Agreement. In the event that any party shall deliver a Demand, the other party
may itself deliver a Demand to such first party with respect to any related
Dispute (with respect to which the Applicable Deadline has not passed) without
the requirement of delivering an Escalation Notice or a Request. In the event
that any party delivers a Demand with respect to any Dispute that is the subject
of any then pending arbitration proceeding or of a previously delivered Demand,
all such Disputes shall be resolved in the arbitration proceeding for which a
Demand was first delivered unless the arbitrator in his or her sole discretion
determines that it is impracticable or otherwise inadvisable to do so.

                  (b) Except as may be expressly provided in any Transaction
Document, any Demand must be given prior to the Applicable Deadline. The parties
may specifically agree in writing to extend or waive the Applicable Deadline
with respect to any Dispute; however, no discussions, negotiations or mediations
between the parties pursuant to this Agreement, or otherwise, will toll the
Applicable Deadline unless expressly agreed in writing by the parties. Each of
the parties agrees that if a Demand is not given prior to the expiration of the
Applicable Deadline, as between or among the parties, such Dispute will be
barred. Subject to Sections 4.05(c) and 4.06 of Article IV of this Agreement,
upon delivery of Demand prior to the Applicable Deadline, the Dispute shall be
decided by a sole arbitrator in accordance with the rules set forth in this
Article IV.

         Section 4.02. ARBITRATORS. (a) Within 15 days after a valid Demand is
received, the parties shall attempt to select a sole arbitrator satisfactory to
both parties.

                  (b) In the event that the parties are not able jointly to
select a sole arbitrator within such 15-day period, the parties shall each
appoint an arbitrator (who need not be disinterested as to the parties or the
matter) within 30 days after delivery of the Demand. If one party appoints an
arbitrator within such time period and the other party fails to appoint an
arbitrator within such time period, the arbitrator appointed by the one party
shall be the sole arbitrator of the matter.

                  (c) In the event that a sole arbitrator is not selected
pursuant to paragraph (a) or (b) above and, instead, two arbitrators are
selected pursuant to paragraph (b) above, the two arbitrators will, within 30
days after the appointment of the later of them to be appointed, select an
additional arbitrator who shall act as the sole arbitrator of the dispute. After
selection of such sole arbitrator, the initial arbitrators shall have no further
role with respect to the dispute. In the event that the arbitrators so appointed
do not, within 30 days after the appointment of the later of them to be
appointed, agree on the selection of the sole arbitrator, any party involved in
such dispute may apply to CPR to select the sole arbitrator, which selection
shall be made by CPR within 30 days after such application. Any arbitrator
selected


                                     -4-
<PAGE>   5

pursuant to this paragraph (c) shall be disinterested with respect to any of the
parties and the matter and shall be reasonably competent in the applicable
subject matter of the Dispute.

                  (d) The sole arbitrator selected pursuant to paragraph (a),
(b) or (c) above will set a time for the hearing of the matter which will
commence no later than 90 days after the date of appointment of the sole
arbitrator pursuant to paragraph (a), (b) or (c) above and which hearing will be
no longer than 30 days (unless in the judgment of the arbitrator the matter is
unusually complex and sophisticated and thereby requires a longer time, in which
event such hearing shall be no longer than 90 days). The final decision of such
arbitrator will be rendered in writing to the parties not later than 60 days
after the last hearing date, unless otherwise agreed by the parties in writing.

                  (e) The place of any arbitration hereunder will be Denver,
Colorado, unless otherwise agreed by the parties.

         Section 4.03. HEARINGS. Within the time period specified in Section
4.02(d) of Article IV of this Agreement, the matter shall be presented to the
arbitrator at a hearing by means of written submissions of memoranda and
verified witness statements, filed simultaneously, and responses, if necessary
in the judgment of the arbitrator or both parties. If the arbitrator deems it to
be essential to a fair resolution of the dispute, live cross-examination or
direct examination may be permitted, but is not generally contemplated to be
necessary. The arbitrator shall actively manage the arbitration with a view to
achieving a just, speedy and cost-effective resolution of the Dispute. The
arbitrator may, in his or her discretion, set time and other limits on the
presentation of each party's case, its memoranda or other submissions, and
refuse to receive any proffered evidence, which the arbitrator, in his or her
discretion, finds to be cumulative, unnecessary, irrelevant or of low probative
nature. Except as otherwise set forth herein, any arbitration hereunder will be
conducted in accordance with the CPR Rules for Non-Administered Arbitration of
Business Disputes then prevailing (except that the fee schedule of CPR will not
apply). Except as expressly set forth in Section 4.06 of Article IV of this
Agreement, the decision of the arbitrator will be final and binding on the
parties, and judgment thereon may be had and will be enforceable in any court
having jurisdiction over the parties. Arbitration awards will bear interest at
an annual rate of the Prime Rate per annum from the date of the award. To the
extent that the provisions of this Agreement and the prevailing rules of the CPR
conflict, the provisions of this Agreement shall govern.

         Section 4.04. DISCOVERY AND CERTAIN OTHER MATTERS. (a) Any party may
request limited document production from the other party of specific and
expressly relevant documents, with the reasonable expenses of the producing
party incurred in such production paid by the requesting party. Any such
discovery (under which rights to documents shall be substantially less than
document discovery rights prevailing under the Federal Rules of Civil Procedure)
shall be conducted expeditiously and shall not cause the hearing provided for in
Section 4.03 of Article IV of this Agreement to be adjourned except upon consent
of both parties or upon an extraordinary showing of cause demonstrating that
such adjournment is necessary to permit discovery essential to a party to the
proceeding. Depositions, interrogatories or other forms of discovery (other than
the document production set forth


                                     -5-
<PAGE>   6

above) shall be permitted only upon an extraordinary showing that such discovery
is essential to a party to the proceeding or upon consent of the parties
involved in the applicable Dispute. Disputes concerning the scope of discovery
(including document production and enforcement of the document production
requests) will be determined by written agreement of the parties or, failing
such agreement, will be referred to the arbitrator for resolution. All discovery
requests will be subject to the parties' rights to claim any applicable
privilege. The arbitrator will adopt procedures to protect the proprietary
rights of the parties and to maintain the confidential treatment of the
arbitration proceedings (except as may be required by law). Subject to the
foregoing, the arbitrator shall have the power to issue subpoenas to compel
discovery.

                  (b) The arbitrator shall have full power and authority to
determine issues of arbitrability but shall otherwise be limited to interpreting
or construing the applicable provisions of the Transaction Documents, including
this Agreement, and will have no authority or power to limit, expand, alter,
amend, modify, revoke or suspend any condition or provision of any of the
Transaction Documents, including this Agreement; it being understood, however,
that the arbitrator will have full authority to implement the provisions of, and
to fashion appropriate remedies for breaches of, the Transaction Documents
including this Agreement (including interim or permanent injunctive relief);
provided that the arbitrator shall not have: (i) any authority in excess of the
authority a court having jurisdiction over the parties and the Dispute would
have absent these arbitration provisions; or, (ii) any right or power to award
punitive, treble or consequential damages except to the extent that any of such
damages are actually paid by a party or a member of a party's Group to a Person.
It is the intention of the parties that in rendering a decision the arbitrator
give effect to the applicable provisions of the Transaction Documents including
this Agreement, and the laws of the State of Ohio without regard to the
principles of conflicts of law thereof (it being understood and agreed that this
sentence shall not give rise to a right of judicial review of the arbitrator's
award).

                  (c) If a party fails or refuses to appear at and participate
in an arbitration hearing after due notice, the arbitrator may hear and
determine the controversy upon evidence produced by the appearing party.

                  (d) Arbitration costs will be borne equally by each party,
except that each party will be responsible for its own attorney's fees and its
other costs and expenses, including the costs of witnesses selected by such
party and all internal costs.

         Section 4.05. CERTAIN ADDITIONAL MATTERS. (a) Any arbitration award
shall be a bare award limited to a holding for or against a party and shall be
without findings as to facts, issues or conclusions of law (including awards
with respect to any matters relating to the validity or infringement of patents
or patent applications) and shall be without a statement of the reasoning on
which the award rests, but must be in adequate form so that a judgment of a
court may be entered thereupon. Judgment upon any arbitration award hereunder
may be entered in any court having jurisdiction thereof.


                                     -6-
<PAGE>   7

                  (b) Prior to the time at which an arbitrator is appointed
pursuant to Section 4.02 of Section IV of this Agreement, any party may seek one
or more temporary restraining orders in a court of competent jurisdiction if
necessary in order to preserve and protect the status quo. Neither the request
for, or grant or denial of, any such temporary restraining order shall be deemed
a waiver of the obligation to arbitrate as set forth herein and the arbitrator
may dissolve, continue or modify any such order. Any such temporary restraining
order shall remain in effect until the first to occur of the expiration of the
order in accordance with its terms or the dissolution thereof by the arbitrator.

                  (c) In the event that at any time the sole arbitrator shall
fail to serve as an arbitrator for any reason, the parties shall select a new
arbitrator who shall be disinterested as to the parties and the matter in
accordance with the procedures set forth herein for the selection of the initial
arbitrator. The extent, if any, to which testimony previously given shall be
repeated or as to which the replacement arbitrator elects to rely on the
stenographic record (if there is one) of such testimony shall be determined by
the replacement arbitrator.

         Section 4.06. LIMITED COURT ACTIONS. (a) Notwithstanding anything
herein to the contrary, in the event that any party reasonably determines the
amount in controversy in any Dispute (or series of related Disputes) is, or is
reasonably likely to be, in excess of $100 million and if such party desires to
commence a lawsuit in lieu of complying with the arbitration provisions of this
Article IV, such party shall so state in its Demand or by notice given to the
other parties within 20 days after receipt of a Demand with respect thereto. If
the other party to the arbitration does not agree that the amount in controversy
in such Dispute (or series of related Disputes) is, or is reasonably likely to
be, in excess of $100 million, the arbitrator selected pursuant to Section 4.02
hereof shall decide whether the amount in controversy in such Dispute (or series
of related Disputes) is, or is reasonably likely to be, in excess of $100
million. The arbitrator shall set a date that is no later than ten days after
the date of his or her appointment for submissions by the parties with respect
to such issue. There shall not be any discovery in connection with such issue.
The arbitrator shall render his or her decision on such issue within five days
of such date so set to the arbitrator. In the event that the arbitrator
determines that the amount in controversy in such Dispute (or such series of
related Disputes) is, or is reasonably likely to be, in excess of $100 million,
the provisions of Sections 4.01, 4.02, 4.03, 4.04, and 4.05 of Article IV of
this Agreement shall not apply, and on or before (but, except as expressly set
forth in Section 4.06(b), not after) the tenth business day after the date of
such decision, either party to the arbitration may elect, in lieu of
arbitration, to commence a lawsuit with respect to such Dispute in any court of
competent jurisdiction. If the arbitrator does not so determine, the provisions
of this Article IV (including with respect to time periods) shall apply as if no
determinations were sought or made pursuant to this Section 4.06(a).

                  (b) In the event that an arbitration award in excess of $100
million is issued in any arbitration proceeding commenced hereunder, any party
may, within 60 days after the date of such award, submit the Dispute giving rise
thereto to a court of competent jurisdiction, regardless of whether such party
or any other party sought to commence lawsuit in lieu of proceeding with
arbitration in accordance with Section 4.06(a) of Article IV of this Agreement.


                                     -7-
<PAGE>   8

In such event, the applicable court may elect to rely on the record developed in
the arbitration or, if it determines that it would be advisable in connection
with the matter, allow the parties to seek additional discovery or to present
additional evidence. Each party shall be entitled to present arguments to the
court with respect to whether any such additional discovery or evidence shall be
permitted and with respect to all other matters relating to the Dispute.

                  (c) No party shall raise as a defense the statute of
limitations if the applicable Demand was delivered on or prior to the Applicable
Deadline and, if applicable, if the matter is submitted to a court of competent
jurisdiction within the 60-day period specified in Section 4.06(b) of Article IV
of this Agreement.

         Section 4.07. CONTINUITY OF SERVICE AND PERFORMANCE. Unless otherwise
agreed in writing, the parties will continue to provide service and honor all
other commitments under the Transaction Documents during the course of
arbitration pursuant to the provisions of this Article IV with respect to all
matters not subject to such Dispute.

                                    ARTICLE V

actually received by the party to which it is addressed in the ordinary course

         2.2 JOINT SAVINGS PLAN. (a) Effective on the Distribution Date, the
GenCorp Retirement Savings Plan and the Profit Sharing Retirement and Savings
Plan of GenCorp Inc. and Certain Participating Subsidiaries will become multiple

                   (b) GenCorp will continue to be both the administrator and
sponsor of the Joint Savings Plan, as defined in ERISA sections 3(16)(A) and
(B), for purposes of complying with the reporting and disclosure requirements
imposed by ERISA and the Code in administering the Joint Savings Plan.

required for compliance with applicable laws, or (ii) GenCorp and OMNOVA
mutually agree to such changes. In addition,

         Savings Plan, will be composed of three (3) members of the GenCorp
         Administrative Committee and two (2) members of the OMNOVA

         Savings Plan, which will have the responsibilities related to
         maintaining relationships with the trustee and investment managers and

         the GenCorp Benefits Management Committee and two (2) members of the
         OMNOVA Benefits Management Committee.

Stock Fund and employer matching contributions on behalf of OMNOVA Employees
will be made solely by OMNOVA and solely to the OMNOVA Stock Fund. Not later

accounts of OMNOVA Employees and former OMNOVA Employees will be transferred to
a new separate savings plan to be established by OMNOVA. Thereafter, neither
OMNOVA nor its employees will participate in the GenCorp Retirement Savings
Plan.

                   (d) Following the Distribution, OMNOVA common stock held in
the accounts of GenCorp employees that is attributable to contributions made
before the Distribution may be retained in the OMNOVA Stock Fund, transferred to
the GenCorp Stock Fund or transferred to any other investment funds in the Joint
Savings Plan at the participant's election in accordance with the terms of the
Joint Savings Plan. Except as provided in the preceding sentence, contributions
made to or held under the Joint Savings Plan on behalf of GenCorp employees may
not be invested in the OMNOVA Stock Fund. OMNOVA common stock held in the
accounts of GenCorp employees that is attributable to employer matching
contributions that have been in the plan for at least two full plan years may be
withdrawn, in cash or in kind. Any dividends on OMNOVA common stock in accounts
of GenCorp employees will be reinvested in the OMNOVA Stock Fund.

                   (e) Following the Distribution, GenCorp common stock held in
the accounts of OMNOVA Employees that is attributable to contributions made
before the Distribution may be retained in the GenCorp Stock Fund, transferred
to the OMNOVA Stock Fund or transferred to any other investment fund in the

of OMNOVA Employees may not be invested in the GenCorp Stock Fund. GenCorp
common stock held in the accounts of OMNOVA Employees that is attributable to
employer matching contributions that have been in the plan at least two full
plan years may be withdrawn, in cash or in kind. Any dividends after the
Distribution Date on GenCorp common stock in accounts of OMNOVA Employees will
be reinvested in the GenCorp Stock Fund.

         2.3 OMNOVA SALARIED PENSION PLAN. (a) OMNOVA shall implement, before
the Closing Time, the OMNOVA Salaried Pension Plan, a qualified defined benefit
plan substantially similar to the GenCorp Salaried Pension Plan for the benefit
of OMNOVA Pension Plan Participants. OMNOVA Salaried Employees shall be eligible
for immediate participation in the OMNOVA Salaried Pension Plan as of the date
their employment is transferred to OMNOVA pursuant to Section 2.1(a). OMNOVA
Salaried Employees shall be credited under the OMNOVA Salaried Pension Plan, for
eligibility and vesting purposes, with the service credited to them under the
GenCorp Salaried Pension Plan. An OMNOVA Salaried Employee shall be credited
under the OMNOVA Salaried Pension Plan, for benefit accrual purposes, with the
service credited to him or her under the GenCorp Salaried Pension Plan only if a
transfer described in subsection (b) of this Section is made with respect to
such OMNOVA Salaried Employee.

                   (b) OMNOVA Salaried Employees shall cease to accrue benefits
under the GenCorp Salaried Pension Plan as of the date their employment is

Plan.

                                       9
<PAGE>   10

                   (c) As soon as practicable after the Distribution Date,
GenCorp shall cause the GenCorp Pension Plan Trustee to segregate within the
GenCorp Pension Plan Trust the Segregated Salaried Pension Assets (as defined in
the following sentence) determined to be allocable with respect to accrued
benefits of OMNOVA Salaried Pension Plan Participants as of the Closing Time.
For purposes of the preceding sentence, the Segregated Salaried Pension Assets
shall mean assets with a value equal to the present value as of the Closing Time
of the accrued benefits of the OMNOVA Salaried Pension Plan Participants under
the GenCorp Salaried Pension Plan, determined by the plan's actuary using
interest assumptions prescribed by the PBGC for valuing annuities in plan
termination situations, plus an amount of surplus assets allocated in proportion
to the allocation of liabilities in accordance with ERISA section 4044.

                   (d) GenCorp and OMNOVA shall make or cause to be made all
required filings and submissions to appropriate governmental and regulatory
authorities and all necessary or appropriate amendments to the GenCorp Salaried
Pension Plan and the OMNOVA Salaried Pension Plan, and shall take all other
steps necessary and appropriate, to permit the transfer of the Segregated
Salaried Pension Assets from the GenCorp Pension Plan Trustee to the OMNOVA
Pension Plan Trustee. As soon as practicable after the filings, submissions,
amendments and other steps described in this subsection are completed, and after
the expiration of any waiting periods imposed under applicable law, GenCorp
shall direct the GenCorp Pension Plan Trustee to transfer to the OMNOVA Pension
Plan Trustee, and OMNOVA shall direct the OMNOVA Pension Plan Trustee to accept
assets of the GenCorp Salaried Pension Plan equal to the Segregated Salaried
Pension Assets, as adjusted for

                                       10
<PAGE>   11

contributions, benefit payments, expenses and investment experience through the
date of such transfer. Such transfer shall be in cash, securities or other
property or a combination thereof, as mutually determined by GenCorp and OMNOVA
and acceptable to both the GenCorp Pension Plan Trustee and the OMNOVA Pension
Plan Trustee. After such transfer, each OMNOVA Salaried Pension Plan Participant
for whom such transfer was made shall be credited with benefits under the OMNOVA
Salaried Pension Plan attributable to service prior to the Closing Time at least
equal to his or her accrued benefit under the GenCorp Salaried Pension Plan, and
the GenCorp Salaried Pension Plan shall have no further obligations with respect
to such accrued benefit. GenCorp and OMNOVA shall prepare a list, certified by a
duly authorized officer of each, of all OMNOVA Salaried Pension Plan
Participants with respect to which a transfer pursuant to this subsection has
been made.

                   (e) GenCorp shall have no obligation to direct the transfer
described in subsection (d) of this Section unless and until GenCorp receives
either a favorable determination letter issued by the IRS as to the qualified
status of the OMNOVA Salaried Pension Plan under Section 401(a) of the code or
an opinion of counsel to OMNOVA that the OMNOVA Salaried Pension Plan meets the
requirements of Section 401(a) of the Code as to form. The OMNOVA Pension Plan
Trustee shall have no obligation to accept any transfer from the GenCorp
Salaried Pension Plan unless and until OMNOVA and the OMNOVA Pension Plan
Trustee receives either a favorable determination letter issued by the IRS as to
the qualified status of the GenCorp Salaried Pension Plan under Section 401(a)
of the Code or an opinion of counsel to GenCorp that the GenCorp Salaried
Pension Plan meets the requirements

                                       11
<PAGE>   12

of Section 401(a) of the Code as to form. GenCorp and OMNOVA will cooperate as
necessary to facilitate obtaining such favorable determination letters.

                   (f) The OMNOVA Salaried Pension Plan shall be a continuation
of the GenCorp Salaried Pension Plan as to the OMNOVA Salaried Pension Plan
Participants for whom the transfer described in subsection (d) of this Section
was made and the transfer of assets and liabilities from the GenCorp Salaried
Pension Plan to the OMNOVA Pension Plan Trustee pursuant to this Agreement shall
not be deemed a termination or partial termination of the GenCorp Salaried
Pension Plan.

                   (g) In the event a former employee of GenCorp who
participated in the GenCorp Salaried Pension Plan prior to the Distribution Date
becomes an OMNOVA Employee eligible to participate in the OMNOVA Salaried
Pension Plan after the Distribution Date, GenCorp and OMNOVA agree that the
liabilities to pay pension benefits to such individual and the assets
attributable to such liabilities, in an amount which (based on the certification
of the actuary for the Plans) meets the requirements of Section 414(1) of the
Code and the regulations thereunder, will be transferred by the GenCorp Pension
Plan Trustee from the GenCorp Salaried Pension Plan to the OMNOVA Salaried
Pension Plan and the OMNOVA Pension Plan Trustee in the manner described in, and
in compliance with, Section 414(1) of the Code and the regulations thereunder.
In the event of any such transfer, such employee shall be credited under the
OMNOVA Salaried Pension Plan, for eligibility, vesting and benefit accrual
purposes, with the service credited to him under the GenCorp Salaried Pension
Plan.

                   (h) The GenCorp Salaried Pension Plan shall provide that an
individual who is an employee of OMNOVA on the Distribution Date shall not be
eligible to commence

                                       12
<PAGE>   13

receiving benefits from the GenCorp Salaried Pension Plan until he terminates
employment with OMNOVA after the Distribution Date. Until the completion of the
transfer of assets and liabilities from the GenCorp Salaried Pension Plan to the
OMNOVA Salaried Pension Plan and the OMNOVA Pension Plan Trustee described in
subsection (c) of this Section, benefits under the OMNOVA Salaried Pension Plan
payable to a OMNOVA Salaried Employee thereunder shall be computed on the basis
of his or her total service with GenCorp and OMNOVA, but shall be reduced by any
benefits accrued by such OMNOVA Salaried Employee under the GenCorp Salaried
Pension Plan.

         2.4 OMNOVA HOURLY PENSION PLAN. (a) OMNOVA shall implement, before the
Closing Time, the OMNOVA Hourly Pension Plan, a qualified defined benefit plan
substantially similar to the GenCorp Hourly Pension Plan for the benefit of
OMNOVA Hourly Pension Plan Participants. OMNOVA Hourly Employees who participate
in the GenCorp Hourly Pension Plan immediately before the Closing Time shall be
eligible for immediate participation in the OMNOVA Hourly Pension Plan as of the
Closing Time. OMNOVA Hourly Employees shall be credited under the OMNOVA Hourly
Pension Plan, for eligibility and vesting purposes, with the service credited to
them under the GenCorp Hourly Pension Plan. An OMNOVA Hourly Employee shall be

with the service credited to him or her under the GenCorp Hourly Pension Plan
only if a transfer described in subsection (b) of this Section is made with
respect to such OMNOVA Hourly Employee.

                  (b) OMNOVA Hourly Employees shall cease to accrue benefits
under the GenCorp Hourly Pension Plan as of the time their employment is
transferred to OMNOVA.

                                       13
<PAGE>   14

Such transfer shall not be an event requiring distribution of benefits under the
GenCorp Hourly Pension Plan.

                   (c) As soon as practicable after the Distribution Date,
GenCorp shall cause the GenCorp Pension Plan Trustee to segregate within the
GenCorp Pension Plan Trust the Segregated Hourly Pension Assets (as defined in
the following sentence) determined to be allocable with respect to accrued
benefits of OMNOVA Hourly Pension Plan Participants as of the Closing Time. For
purposes of the preceding sentence, the Segregated Hourly Pension Assets shall
mean assets with a value equal to the present value as of the Closing Time of
the accrued benefits of the OMNOVA Hourly Pension Plan Participants under the
GenCorp Hourly Pension Plan, determined by the plan's actuary using interest
assumptions prescribed by the PBGC for valuing annuities in plan termination
situations, plus an amount of surplus assets allocated in proportion to the
allocation of liabilities in accordance with ERISA section 4044.

                   (d) GenCorp and OMNOVA shall make or cause to be made all
required filings and submissions to appropriate governmental and regulatory
authorities and all necessary or appropriate amendments to the GenCorp Hourly
Pension Plan and the OMNOVA Hourly Pension Plan, and shall take all other steps
necessary and appropriate, to permit the transfer of the Segregated Hourly
Pension Assets from the GenCorp Pension Plan Trustee to the OMNOVA Pension Plan
Trustee. As soon as practicable after the filings, submissions, amendments and
other steps described in this subsection are completed, and after the expiration
of any waiting periods imposed under applicable law, GenCorp shall direct the
GenCorp Pension Plan Trustee to transfer to the OMNOVA Pension Plan Trustee, and
OMNOVA shall

                                       14
<PAGE>   15

direct the OMNOVA Pension Plan Trustee to accept assets of the GenCorp Hourly
Pension Plan equal to the Segregated Hourly Pension Assets, as adjusted for
contributions, benefit payments, expenses and investment experience through the
date of such transfer. Such transfer shall be in cash, securities or other
property or a combination thereof, as mutually determined by GenCorp and OMNOVA
and acceptable to both the GenCorp Pension Plan Trustee and the OMNOVA Pension
Plan Trustee. After such transfer, each OMNOVA Hourly Pension Plan Participant
for whom such transfer was made shall be credited with benefits under the OMNOVA
Hourly Pension Plan attributable to service prior to the Closing Time at least
equal to his or her accrued benefit under the GenCorp Hourly Pension Plan, and
the GenCorp Hourly Pension Plan shall have no further obligations with respect
to such accrued benefit. GenCorp and OMNOVA shall prepare a list, certified by a
duly authorized officer of each, of all OMNOVA Hourly Pension Plan Participants
with respect to which a transfer pursuant to this Subsection has been made.

                   (e) GenCorp shall have no obligation to direct the transfer
described in subsection (d) of this Section unless and until GenCorp receives
either a favorable determination letter issued by the IRS as to the qualified
status of the OMNOVA Hourly Pension Plan under Section 401 (a) of the code or an
opinion of counsel to OMNOVA that the OMNOVA Hourly Pension Plan meets the
requirements of Section 401(a) of the Code as to form. The OMNOVA Pension Plan
Trustee shall have no obligation to accept any transfer from the GenCorp Hourly
Pension Plan unless and until OMNOVA and the OMNOVA Pension Plan Trustee
receives either a favorable determination letter issued by the IRS as to the
qualified status of the GenCorp Hourly Pension Plan under Section 401(a) of the
Code or an

<PAGE>   16

opinion of counsel to GenCorp that the GenCorp Hourly Pension Plan meets the
requirements of Section 401(a) of the Code as to form. GenCorp and OMNOVA will
cooperate as necessary to facilitate obtaining such favorable determination
letters.

                   (f) The OMNOVA Hourly Pension Plan shall be a continuation of
the GenCorp Hourly Pension Plan as to the OMNOVA Hourly Pension Plan
Participants for whom the transfer described in subsection (d) of this Section
was made and the transfer of assets and liabilities from the GenCorp Hourly
Pension Plan to the OMNOVA Pension Plan Trustee pursuant to this Agreement shall
not be deemed a termination or partial termination of the GenCorp Hourly Pension
Plan.

                   (g) The GenCorp Hourly Pension Plan shall provide that an
individual who is an employee of OMNOVA on the Distribution Date shall not be
eligible to commence receiving benefits from the GenCorp Hourly Pension Plan
until he terminates employment with OMNOVA after the Distribution Date. Until

Pension Plan to the OMNOVA Hourly Pension Plan and the OMNOVA Pension Plan
Trustee described in subsection (c) of this Section, benefits under the OMNOVA
Hourly Pension Plan payable to an OMNOVA Hourly Employee thereunder shall be

Medical Plan made available to OMNOVA Employees and their dependent(s) as of the
Closing Time shall waive any applicable waiting periods for coverage of OMNOVA
Employees and their dependent(s) which did not exist with respect to such OMNOVA
Employee or dependent(s) immediately prior to the Closing Time. The OMNOVA
Medical Plan shall not contain any exclusion or limitation with respect to any
pre-existing condition of any OMNOVA Employee or dependent(s) which did not
apply with respect to such OMNOVA Employee or dependent immediately prior to the
Closing Time. For purposes of the two preceding sentences, service with GenCorp

meeting any such waiting period or pre-existing condition, exclusion or
limitation.

reimbursement plan and a pre-tax premium plan (collectively referred to as the
"OMNOVA Flexible Benefit Plan") with provisions substantially similar to similar
plans provided to OMNOVA Employees by GenCorp prior to the Closing Time; and
(ii) Plan Year 1999 deferrals and reimbursements by or to OMNOVA Employees under
the GenCorp Flexible Benefit Plan, shall be carried over and applied to their
accounts under the OMNOVA Flexible Benefit Plan. Within a reasonable time after
the Closing Time, GenCorp will pay to OMNOVA the net aggregate dependent day
care reimbursement and health care reimbursement account balances of OMNOVA
Employees held by GenCorp as of the Closing Time.

         2.6 POSTRETIREMENT BENEFITS. GenCorp currently provides certain health
care and life insurance benefits to most retired employees in the United States
with varied coverage by employee groups. The health care plans generally provide
for cost sharing in the form of retiree contributions, deductibles and
coinsurance between the company and its retirees. A portion of the unfunded
benefit obligation reported in GenCorp's financial statements for such
postretirement benefits attributable to OMNOVA Hourly Employees and former
employees of GenCorp who terminated employment from (i) business locations of
OMNOVA active as of the Closing Time, and (ii) the former GenCorp business
location in Newcomerstown, Ohio, will be assumed by OMNOVA.

         2.7 GENCORP 1993 AND 1997 STOCK OPTION PLANS. (a) Prior to the
Distribution Date, exercisable options under the GenCorp 1993 and 1997 Stock
Option Plans for (1) active employees, (2) retirees, and (3) other former
employees whose options remain exercisable, will be split into options to
acquire GenCorp common stock and OMNOVA common stock. Except with respect to
options held by the chief executive officers of GenCorp and OMNOVA, the

                                       18
<PAGE>   19

number of exercisable options in each company will each equal the number of
exercisable options under the GenCorp Stock Option Plans. With respect to
exercisable options held by the chief executive officers, (1) Mr. Wolfe's
options will be converted into 66 2/3% GenCorp options and 33 1/3% OMNOVA
options, and (2) Mr. Yasinsky's options will be converted into 66 2/3% OMNOVA
options and 33 1/3% GenCorp options. The exercise price of each resulting option
will bear the same ratio to the market price, as of the Distribution Date, of
the respective company's stock, as the exercise price of the original GenCorp
option bore to the market price of GenCorp shares immediately before the
Distribution Date. GenCorp and OMNOVA agree that each will issue the appropriate
shares of their common stock to non-employees who exercise the options described
in this subsection (a).

                   (b) Unexercisable options under the GenCorp 1997 Stock Option
Plan for GenCorp employees will be replaced with a number of unexercisable
GenCorp options under that plan which will, based upon (1) the market price of
GenCorp shares immediately after the Distribution Date and (2) the exercise
prices for those options, have an aggregate intrinsic value equal to that of the
unexercisable GenCorp options immediately before the Distribution Date.

                   (c) Unexercisable options under the GenCorp 1997 Stock Option
Plan for OMNOVA Employees will be replaced with a number of unexercisable OMNOVA
options which will, based upon (1) the market price of OMNOVA shares immediately
after the Distribution Date and (2) the exercise price for such options, have an
aggregate intrinsic value equal to that of the unexercisable GenCorp options
immediately before the Distribution.

                                       19
<PAGE>   20

                   (d) In converting the stock option plans for the
Distribution, the exercisable and unexercisable aggregate intrinsic value of the
options immediately after the conversion will be equal to the aggregate
intrinsic value immediately before the conversion. The ratio of the exercise
price per option to the market value per share will not be reduced and the
vesting provisions and option period of the OMNOVA and GenCorp options will be
the same as for the original GenCorp options. Accordingly, no compensation
expense will be recognized by OMNOVA or GenCorp.

         2.8  UNFUNDED DEFERRED COMPENSATION.

                   (a) Subject to legal requirements for employee acquiescence,
GenCorp's legal obligation to pay Unfunded Deferred Compensation for: (1) all
active employees transferred to OMNOVA, (2) all retired employees who terminated
employment from business locations of OMNOVA which are active as of the Closing
Time, and (3) all GenCorp directors resigning to become members of the OMNOVA
Board will be assumed by OMNOVA.

                   (b) The legal obligation to pay Unfunded Deferred
Compensation for: (1) all active employees remaining GenCorp employees, (2) all
GenCorp directors remaining on the GenCorp Board, (3) all other retired
employees, and (4) all retired directors, will be retained by GenCorp.

                   (c) Former employees and directors of GenCorp or OMNOVA will
be able to elect a lump-sum payment of their Unfunded Deferred Compensation,
subject to (1) a 10% reduction in order to avoid adverse tax consequences, and
(2) all applicable tax withholding. Active employees and directors may receive
lump-sum payments of their Unfunded Deferred Compensation upon termination of
employment or board service with GenCorp or OMNOVA

                                       20
<PAGE>   21

based upon appropriate advance elections or discretionary approval by the
company's benefit management committee.

                   (d) GenCorp hereby indemnifies OMNOVA for the obligations to
pay Unfunded Deferred Compensation assumed by OMNOVA pursuant to subsection (a),
and will pay only those amounts of such Unfunded Deferred Compensation that
OMNOVA proves it is unable to pay.

                   (e) OMNOVA hereby indemnifies GenCorp for the obligation to
pay Unfunded Deferred Compensation retained by GenCorp pursuant to subsection
(b), and will pay only those amounts of Unfunded Deferred Compensation that
GenCorp proves it is unable to pay.

         2.9 ANNUAL BONUSES. Bonus amounts under GenCorp's Executive Incentive
Compensation Plan for the period ending November 30, 1999 will be determined
based upon (1) actual performance up to the Distribution Date, and (2) budgeted
performance, for the remainder of the period, according to GenCorp's annual
operating plan. Subject to all legal requirements for employee acquiescence,
bonus obligations will be assumed by OMNOVA for all OMNOVA Employees, and paid
in cash on January 3, 2000. Bonus obligations will be paid in cash on January 3,
2000 by GenCorp for all GenCorp employees and for terminated GenCorp employees
who are not employed by OMNOVA.

         2.10 LONG TERM INCENTIVE COMPENSATION. Performance awards under
GenCorp's Long-Term Incentive Program for the three-year performance period
ending November 30, 1999 will be determined based upon (1) actual performance up
to the Distribution Date, and (2) budgeted performance, for the remainder of the
period, according to GenCorp's annual

                                       21
<PAGE>   22

operating plan. Pro rata performance awards will be paid under the GenCorp plan
for the performance periods ending November 30, 2000 and November 30, 2001. Pro
rata performance awards for each partial performance period will be determined
based upon (1) actual performance up to the Distribution Date, and (2) budgeted
performance, for the remainder of the fiscal year ending November 30, 1999,
according to GenCorp's annual operating plan. Subject to legal requirements for
employee acquiescence, performance award obligations for the three-year
performance period ending November 30, 1999 will be assumed by OMNOVA for all
OMNOVA Employees and paid in cash on January 3, 2000. Performance award
obligations for the three-year performance period ending November 30, 1999 will
be paid in cash on January 3, 2000 by GenCorp for all GenCorp employees and for
terminated GenCorp employees who are not employed by OMNOVA. All pro rata
performance awards will be paid in cash to all eligible employees of GenCorp and
OMNOVA by GenCorp on the day preceding the Distribution Date.

         2.11 DIRECTOR COMPENSATION. Subject to legal requirements for director
acquiescence, benefit obligations under the Retirement Plan for Nonemployee
Directors of GenCorp Inc. and the Deferred Compensation Plan for Nonemployee
Directors of GenCorp Inc. (hereafter the "GenCorp Director Plans") for GenCorp
directors resigning to become members of the OMNOVA Board will be assumed by
OMNOVA. Benefit obligations under the GenCorp Director Plans for GenCorp
directors remaining on the GenCorp Board and retired directors will be retained
by GenCorp.

         2.12 ENHANCED RETIREMENT AND SEPARATION PAY PLANS. GenCorp adopted a
Voluntary Enhanced Retirement Program (VERP) and Enhanced Involuntary Separation
Pay Plan (EISP)

                                       22
<PAGE>   23

which are associated with and contingent upon the Distribution. Pension and
Separation Pay obligations under the VERP and EISP for GenCorp employees who
become OMNOVA Employees in connection with the Spin-Off will be assumed and paid
by OMNOVA. Pension and Separation Pay obligations under the VERP and EISP for
GenCorp employees who do not become employed by OMNOVA in connection with the
Spin-Off will be retained and paid by GenCorp. The total number and identity of
participants and the timing of their departure are not yet known.

         2.13 TRANSITION ADMINISTRATIVE SERVICES. For a transition period
extending up to October 31, 2001, the Joint Savings Plan and other benefit
programs currently applicable to GenCorp active employees and retirees will be
administered under a Services and Support Agreement between GenCorp and OMNOVA.
The purpose of the transition services arrangement will be to allow for an
orderly transition of administrative responsibility for ongoing GenCorp benefit
programs to administrative staffs of GenCorp, and for the implementation and
administration of new employee benefit plans for OMNOVA. In accordance with the
Services and Support Agreement, (i) GenCorp will reimburse OMNOVA specified
allocated costs plus all direct expenses incurred by OMNOVA on behalf of
GenCorp, and (ii) OMNOVA will reimburse GenCorp specified allocated costs plus
all direct expenses incurred by GenCorp on behalf of OMNOVA.

DATE. GenCorp shall retain sole responsibility for (a) payments of any and all
wages, vacation pay, bereavement pay, jury duty pay, disability income,
supplemental unemployment benefits, fringe benefits (excluding medical/dental
claims described in Section 2.5(b)) or other

                                       23
<PAGE>   24

perquisites of employment, or similar benefits, payroll taxes and other payroll
related expenses, (b) workers' compensation claims or related litigation claims,

litigation claims and (d) other similar employment-related claims, in any such
case arising out of or relating to (i) the employment of the OMNOVA Employees by
GenCorp prior to the Closing Time or (ii) the employment of former employees
whose employment with OMNOVA or GenCorp or the Controlled Group of either
terminated on or before the Closing Time.

         2.15 AT WILL EMPLOYMENT. Nothing in this Agreement shall limit the at
will nature of the employment of any of the OMNOVA Employees who do not have any
other contractual rights with respect to employment by OMNOVA or the right of
GenCorp or OMNOVA to alter or terminate any employee benefit plan.

         2.16 SEPARATION PAY. GenCorp and OMNOVA agree that with respect to
individuals who, in connection with the Distribution, cease to be employees of
GenCorp and become employees of OMNOVA at any time prior to the day after the
Distribution, such cessation shall not be deemed a severance of employment from
GenCorp for purposes of the GenCorp Involuntary Separation Pay Plan. GenCorp
shall retain and be solely responsible for, and shall indemnify OMNOVA against,
all liabilities and obligations whatsoever in connection with claims made by or
on behalf of former employees of GenCorp in respect of separation pay and
similar obligations relating to the termination or alleged termination of any
such person's employment from GenCorp on or before the Distribution Date.

Procedure 84-77, 1984-2

C.B. 753, with respect to filing and furnishing Internal Revenue Service Forms

"predecessor-successor" basis as set forth therein; (b) GenCorp shall be
relieved from furnishing Forms W-2 to GenCorp's employees whose employment is
transferred to OMNOVA in connection with the Spin-Off and to whom GenCorp would
have been obligated to furnish such Forms; and (c) OMNOVA shall assume GenCorp's
obligation to furnish such Forms to all such employees for the full 1999
calendar year. Upon OMNOVA's request, GenCorp will promptly provide OMNOVA with
the information relating to periods ending on the Closing Time necessary for
OMNOVA to prepare and distribute Forms W-2 to such employees for the year ending
December 31, 1999, which Forms W-2 will include all remuneration earned by such
employees from both GenCorp and OMNOVA during the year ending December 31, 1999.

provide the other, as soon as practicable after the Distribution Date, with such

party hereto shall afford the other party and its accountants, counsel and other

                                       25

business hours) to all records, books, contracts, instruments, computer data and
other data and information in such party's possession relating to the business
and affairs of such other party (other than data and information subject to an

required by such other party including, without limitation, for audit,
accounting and litigation purposes and administration of employee benefit plans,
as well as for purposes of fulfilling disclosure and reporting obligations.

                   (b) For a period of up to 24 months from and after the
Distribution Date, (or longer as required in connection with the Joint Savings
Plan) each party shall make available to the other during normal business hours
and in a manner which will not unreasonably interfere with such party's
business, its financial, tax, accounting, legal, employee benefits and such
other staff and services to the extent that the same may be reasonably required
in connection with the preparation of tax returns, audits, claims,
administration of employee benefit plans and otherwise to assist in effecting an

                         SERVICES AND SUPPORT AGREEMENT

         This Services and Support Agreement ("Agreement"), dated as of
September __, 1999, is made and entered into by and between GENCORP INC., an
Ohio corporation ("GenCorp"), and OMNOVA SOLUTIONS INC., an Ohio corporation
("OMNOVA") and a wholly-owned subsidiary of GenCorp.

                                   WITNESSETH:

         WHEREAS, the Board of Directors of GenCorp has determined that it is
advisable to distribute substantially all of the stock of OMNOVA to its
shareholders in a transaction intended to qualify under Section 355 of the
Internal Revenue Code (variously, the "Distribution" or the "Spin-Off");

         WHEREAS, GenCorp and OMNOVA are entering into a Distribution Agreement
(the "Distribution Agreement") which, among other things, sets forth the
principal transactions required to effect the Distribution and sets forth other
agreements that will govern certain other matters following the Distribution;
and

         WHEREAS, in connection with the Distribution, GenCorp and OMNOVA have
agreed to enter into this Agreement in order for OMNOVA and GenCorp each to
assist the other by providing to the other certain services and support not
otherwise specified in any of the Ancillary Agreements (as defined in the
Distribution Agreement);

         NOW THEREFORE, in consideration of these premises and the mutual
promises and conditions contained herein, GenCorp and OMNOVA hereby agree as
follows:

                                       2
<PAGE>   2

                                    ARTICLE I

                                      TERM

         1.1 TERM OF THE AGREEMENT. The term of this Agreement shall be from the
date hereof (the "Effective Date") to and including the later of (i) the second
anniversary of the Distribution, and (ii) October 31, 2001 (the "Term"),
although the actual duration of specific services may be for a shorter period as
provided herein. The Term may be extended by the mutual agreement of GenCorp and
OMNOVA.

                                   ARTICLE II

                                    SERVICES

         2.1 SERVICES PROVIDED BY OMNOVA. OMNOVA shall provide to GenCorp during
the Term of this Agreement the services listed on Schedule A attached hereto.
The services listed on Schedule A are based on the understanding of the parties
hereto of the support and administrative services reasonably required by GenCorp
at the date of this Agreement. If, following the Distribution, GenCorp
reasonably determines that additional services consistent with the recent
historical practice of GenCorp should be provided by OMNOVA, the parties agree
to negotiate in good faith to modify this Agreement appropriately with respect
