PART I

ITEM 1.  BUSINESS

McWhorter Technologies, Inc. (McWhorter or the Company) is a leading 
manufacturer of surface coating resins and colorants and is a manufacturer of 
resins used in the reinforced fiberglass plastics industry.  Surface coating 
resins are a primary component of paint and coatings which are used for a 
variety of protective and decorative purposes.  Colorants are used to 
disperse pigments in paints and coatings.  Resins used for reinforced 
fiberglass plastics are a primary component for various fiberglass products. 
The Company strengthened its global presence with the purchase of the equity 
interests of its joint venture partners in McWhorter Technologies Europe in 
the first quarter of 1998. As a result, the Company increased its equity 
interest in McWhorter Europe from 33% to 100%. On April 1, 1998, the Company 
completed the acquisition of Accurate Coatings and Dispersions, Inc. 
(Accurate). Accurate, located in South Holland, Illinois, manufactures and 
distributes colorants for the coatings industry. The acquisition of Accurate 
expands McWhorter's presence in the colorant market and better enables the 
Company to serve its customers. McWhorter purchased Arizona Chemical's 
customer list and technology related to its European alkyd resin business in 
April 1998.

All references to years are to fiscal years ended October 31 unless otherwise 
stated.

PRODUCTS AND MARKETS
McWhorter's product lines focus primarily on the requirements of customers in 
the paint and coatings and reinforced fiberglass plastics industries. Each of 
these industries are highly fragmented with a large number of competitors. 
For example, in the paint and coatings industry, McWhorter believes there are 
over 800 active companies manufacturing paint and coatings for a variety of 
end uses.

The paint and coatings industry is a mature market, growing at an estimated 
2% per annum, or about the same rate as durable goods.  Although a number of 
paint and coating manufacturers have captive resin and colorant manufacturing 
capabilities today, increased costs of product reformulation and updating of 
resin and colorant manufacturing processes to comply with environmental 
regulations are causing a shift from captive manufacturing to outsourcing. 
McWhorter believes this trend will increase its sales opportunities in future 
years.

McWhorter produces various products including alkyds, copolymers, 
polyurethanes, polyester resins, unsaturated polyesters, acrylic emulsions, 
polyvinyl acetate emulsions, solution acrylics, powder resins, powder curing 
agents, a number of specialty resins, and waterborne and solvent-based 
colorant systems.  Various types of resins are required by customers due to 
differing application and product performance characteristics.

ALKYD RESINS AND COPOLYMERS.  Alkyd resins and copolymers are McWhorter's 
largest product category and are used in the manufacture of oil-based paints 
and coatings.  Alkyd resins and copolymers can be used in consumer paints 
(e.g., house paint, deck stains, etc.), industrial coatings (e.g., decorative 
and protective coatings used on machinery, equipment, tools, etc.) and 
special purpose coatings (e.g., traffic-striping paints, automotive refinish 
coatings, and industrial maintenance coatings). Alkyd resins and copolymers 
are formulated and engineered according to customer specifications for 
various purposes and the same product can be used in 

                                                                     3

<PAGE>

different applications depending on the product's formulation.  Alkyd resins 
and copolymers can also be modified with other raw materials to improve 
performance; silicone for longer-lasting products or high temperature 
applications, vinyl toluene for quicker-dry applications, and acrylics for 
improved durability.

POLYURETHANE RESINS.  Oil-modified polyurethane resins are a form of an alkyd 
resin used primarily in varnishes and other clear wood coatings for 
application on wood floors, furniture, kitchen cabinets, etc.  Oil-modified 
polyurethane resins are also used as additives to floor coatings and other 
products to improve a product's performance characteristics.

POLYESTER RESINS.  Polyester resins are used in industrial coatings requiring 
specific properties such as gloss and color retention, resistance to 
corrosion, and flexibility.  Typical uses for polyesters are coil coated 
metal buildings, appliances and metal office furniture.

UNSATURATED POLYESTER RESINS.  Unsaturated polyester resins are used for 
various applications in the reinforced fiberglass plastics industry.  The 
largest uses are marine applications where unsaturated polyester resins are 
used in the manufacture of boats.  Other applications include tub and shower 
enclosures, fiberglass tanks, and cultured marble surfaces.

ACRYLIC AND POLYVINYL ACETATE EMULSION RESINS.  Acrylic and polyvinyl acetate 
emulsion resins are used primarily in consumer latex paints.  Acrylic 
emulsion resins are used in trim paints and exterior applications where 
weathering, color and gloss retention are critical.  Emulsions are also used 
in industrial and special purpose coatings.  The major advantage of acrylic 
emulsion resins is their ability to meet or exceed environmental regulations 
because of their low solvent content.

SOLUTION ACRYLICS.  Solvent-borne acrylic resins are used in applications 
where resistance to weathering is required.  Coatings produced from 
solvent-borne acrylic resins may be thermoplastic or may be combined with 
crosslinkers to form high performance thermoset coatings.  Typical 
applications include marine and maintenance paints and automotive topcoats.

POWDER RESINS.  Powder resins are used in the manufacture of industrial 
powder coatings.  Powder coatings are dry coatings which provide an 
alternative to liquid coatings.  The principal advantage of powder coatings 
are that they emit no solvents, have excellent application and performance 
characteristics, and have a high degree of transfer efficiency.  Powder 
coatings is the fastest growing segment of the industrial coatings industry.

POWDER CURING AGENTS.  Powder curing agents are used in conjunction with certain
powder resins to impart durability and hardness.  McWhorter produces urethane
curing agents, the largest volume category for powder paint.

                                                                     4
<PAGE>

SPECIALTY RESINS.  Specialty resins include natural and synthetic adhesives 
used in the paper industry.  These resins are used for high pressure 
laminates and surface particle boards including water-soluble amino resins 
for treated panels and laminated plastics and phenol formaldehyde resins for 
laminated plastics.

WATERBORNE AND SOLVENT-BASED COLORANT SYSTEMS.  Colorants are used in 
formulated interior and exterior paints, specifically, exterior aerospace 
applications, topcoat and interior applications for vehicles, general and 
light industrial, coil coatings for builders panels, and coatings for 
beverage containers.

SALES AND DISTRIBUTION
McWhorter sells its products primarily to customers in the paint and coatings
and reinforced fiberglass plastics industry through a direct sales force, with
the balance sold through agents or distributors.  McWhorter's business is
primarily focused in North America and Europe.  

McWhorter's business is somewhat seasonal with sales volume being 
traditionally the highest during the third quarter of its fiscal year.  This 
seasonality is largely due to the buying cycle of the consumer paint and 
maintenance coatings businesses.  Since orders are generally filled within a 
minimum lead time, McWhorter has no significant backlog.

MANUFACTURING AND RESEARCH AND DEVELOPMENT
McWhorter operates its manufacturing plants 24 hours a day on a five- or 
seven-day schedule, depending on local work practices, capacity utilization, 
and customer requirements.

Solvent-based products are generally produced in high temperature reactors.  
Raw materials are fed into a reactor and heated to 400DEG. -500DEG. F for 
10-30 hours, depending on the formulation.  Once the desired properties are 
achieved, the product is transferred to a mixing vessel, where additional 
materials are added to complete the batch.  Finally, the resin is filtered 
and pumped into drums or bulk storage tanks before shipment to customers.

Emulsions are processed differently from solvent-based resins.  Emulsions are 
created by exothermic reactions in reactors designed to control the reaction 
by cooling the product.  Once the reaction is complete, material is filtered 
and transferred to bulk storage tanks before shipment to customers.

Colorants are produced by mixing precise amounts of pigment and solvent at 
low temperatures. Once the desired dispersion is attained, the product is 
filtered and then pumped into drums for shipment to customers.

McWhorter manufactures certain proprietary resins under tolling arrangements, 
which are common in the resin industry.  Such arrangements are subject to 
confidentiality and secrecy agreements which safeguard the customer's 
technology.  

McWhorter's research and development activities have emphasized emerging 
technologies in the paint and coatings industry, focusing on developing 
products designed to comply with 

                                                                     5
<PAGE>

environmental laws and maintain the integrity of a product's performance 
characteristics.  In 1998, McWhorter completed construction of a new 42,000 
square-foot corporate technology center in Carpentersville, Illinois, which 
accommodates the Company's U.S. product development, information technology, 
technical service, and marketing and sales personnel. 

RAW MATERIALS
Materials used in the manufacturing of resins and colorants are procured 
primarily from domestic suppliers.  Most of the raw materials are derived 
from either petroleum or vegetable oil.  McWhorter has not experienced 
difficulty in recent years in obtaining an adequate supply of raw materials 
or other supplies needed in the manufacturing process.  The majority of the 
materials purchased are subject to national supply contracts which generally 
average one to three years in length with pricing subject to periodic reviews 
and adjustment based on market conditions.  Raw material prices fluctuate due 
to market conditions in the petrochemical or vegetable oil markets.  

INTELLECTUAL PROPERTY
McWhorter's business is not materially dependent upon franchises, licenses or
similar rights, or on any single patent or trademark or group of related patents
or trademarks.  The techniques and formulas used to produce solvent-based resins
are mature and well known.  The techniques and formulas used to produce acrylic
emulsions, powder resins, curing agents, other specialty resins and colorants
are in some instances not well known or are protected by patents or as trade
secrets.

COMPETITION
McWhorter encounters competition from numerous other companies with respect to
each of the products it produces.  A significant number of resin and colorant
producers are vertically integrated into coatings manufacturers, providing a
captive source of products for such manufacturers.  Some of these captive
producers also sell directly to third parties.  

Consistent quality, responsive service, technology and price are the critical 
elements that customers use to select their resin and colorant suppliers. 
McWhorter believes that it competes favorably in each of these areas.

EMPLOYEES
McWhorter employs approximately 1,040 full- and part-time employees worldwide. 

ITEM 2.  PROPERTIES

The Company's principal plants and facilities have an aggregate square footage
of approximately 1,027,000 square feet, of which 73%, or 745,000 square feet, is
located in the U.S., and approximately 27%, or 282,000 square feet, is located
outside the U.S., primarily in 

                                                                     6

<PAGE>

Italy and Sweden.  Approximately 97% of the square footage is owned and the 
balance is held under lease. All facilities are well maintained, utilized for 
their intended purpose, and have sufficient capacity to meet their 
reasonably-anticipated needs.  There are no material encumbrances on any of 
the facilities. Total practical production capacity of McWhorter's plant 
facilities is approximately 896 million wet pounds per year.  The Company's 
corporate headquarters is located in Carpentersville, Illinois.

ITEM 3.  LEGAL PROCEEDINGS AND ENVIRONMENTAL MATTERS

McWhorter is involved in an administrative proceeding with the California 
Department of Toxic Substances Control (DTSC). McWhorter is appealing a 
Corrective Action Order issued by the DTSC. Because of the subjective nature 
of the Order's requirements and the pending ruling upon the Order's merits 
and validity, it is impossible to quantify any potential resulting impact to 
liabilities. Other than the above, McWhorter is not party to any legal or 
administrative proceedings, other than routine litigation incidental to the 
business or involving claims for immaterial amounts.   

The operations of McWhorter, like those of other companies in its industry, 
involve the generation and disposal of substances regulated by the United 
States Environmental Protection Agency and certain state agencies under 
various federal and state environmental laws.  As a result, McWhorter is 
involved in various claims relating to environmental and waste disposal 
matters.  These claims generally allege that McWhorter, together with other 
parties, is responsible under federal and state environmental laws for the 
remediation of hazardous waste at a particular site.  Several of these laws 
provide that potentially responsible parties may be held jointly and 
severally liable for investigation and remediation costs regardless of fault. 
Although McWhorter continually assesses its potential liability with respect 
to its past and present operations, any potential liability that may be 
attributable to McWhorter is subject to a number of uncertainties, including, 
among others, the number of parties involved with respect to any given site, 
the volumetric contribution which may be attributed to McWhorter relative to 
that attributable to other parties, the nature and magnitude of the wastes 
involved, and the method and extent of remediation.  McWhorter does not 
believe that any potential liability, either individually or in the 
aggregate, ultimately determined to be attributable to McWhorter will have a 
material adverse effect on its business or financial condition.  

At October 31, 1998 the estimated amount of probable environmental liability of
McWhorter is approximately $3,420,000.  Cargill Incorporated (Cargill) has
agreed to indemnify McWhorter, subject to certain limitations, for damages
resulting from certain environmental matters relating to its former Resin
Products Division (RPD) that was acquired by the Company in 1994. 
Indemnification for environmental liabilities, subject to certain limitations,
related to the Company's Italian facilities is provided for under the escrow
provisions of the Syntech S.p.A. acquisition agreement.  As a result of the
probable recoveries under these indemnification agreements of $2,722,000, 
McWhorter's net estimated environmental liability is approximately $698,000. 
There are a total of twelve sites at which McWhorter believes it has probable
environmental liability, including three sites for which the estimated liability
is 

                                                                     7

<PAGE>

less than $10,000 per site.  The maximum estimated amount of environmental 
liability attributable to any individual site is approximately $945,000, of 
which a significant portion is expected to be reimbursed.  During 1998, 
McWhorter spent approximately $693,000 on remediation costs, of which 
$584,000 was spent for on-site liabilities and has been or is expected to be 
reimbursed. During 1999, McWhorter expects to spend approximately $1,854,000 
on remediation costs, of which $1,416,000 is expected to be reimbursed under 
the indemnification agreeements.  During 1998, McWhorter spent approximately 
$1,279,000 on capital expenditures to comply with environmental laws and 
regulations and during 1999 McWhorter expects to spend approximately 
$2,200,000 on such expenditures.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

There were no matters submitted to a vote of security holders during the 
fourth quarter of 1998.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
         FINANCIAL CONDITION

The following discussion and analysis should be read in conjunction with the
Consolidated Financial Statements and Notes. All references to years are to
fiscal years ended October 31 unless otherwise stated.  Unless otherwise stated,
per share information is on a diluted basis.

OVERVIEW The Company's net sales surpassed the levels achieved in all prior 
years as a result of strategic acquisitions completed in 1998 and 1997. In 
April 1998, the Company completed the acquisition of substantially all of the 
assets of Accurate Coatings and Dispersions, Inc. (Accurate) for 
approximately $39,400,000 in cash and the assumption of $6,500,000 of debt.  
Accurate, located in South Holland, Illinois, manufactures and distributes 
dispersed pigments for the coatings industry. The Company strengthened its 
global presence with the purchase of the equity interests of its joint 
venture partners in McWhorter Technologies Europe (McWhorter Europe) for 
approximately $8,200,000 in the first quarter of 1998.  As a result, the 
Company increased its equity interest in McWhorter Europe from 33.3 percent 
to 100 percent.  In April 1998, the Company purchased Arizona Chemical's 
customer 

                                                                     9

list and technology related to its European alkyd resin business.  In August 
1997, the Company completed the acquisition of Syntech S.p.A. and its 
affiliated entities and subsidiaries (Syntech) for $48,300,000 in cash and 
approximately $17,100,000 in assumed liabilities. Syntech is an Italian based 
resin company with two production facilities in Italy and a joint venture in 
China. These acquisitions were accounted for using the purchase method. Refer 
to Note 2 of the Notes to Consolidated Financial Statements.

The Company completed the construction of a 42,000 square foot research and 
development facility in Carpentersville, Illinois during 1998. As a result of 
this project, the Company closed its research and development facility in 
Minneapolis, Minnesota. Employees from the product development, technical 
support, and information technology groups were relocated to the new facility 
to serve McWhorter's liquid coating resins, powder coating resins, and 
composite polymers businesses.  In total, the Company incurred pretax charges 
of $1,546,000, $.09 per share after taxes, related to this move.  Refer to 
Note 14 of the Notes to Consolidated Financial Statements.

In August 1998, the Company announced plans to close its manufacturing 
facility in Chicago Heights, Illinois and to write-off its investment in the 
McWhorter Thailand joint venture. Pretax charges related to these plans of  
$4,650,000, $.27 per share after taxes, and $2,617,000, $.15 per share after 
taxes, respectively, were recorded in the fourth quarter of 1998. Additional 
pretax charges of approximately $650,000 related to the retention of 
employees at the Chicago Heights facility will be recorded in conjunction 
with the closing of the facility.  The planned closure of the Chicago Heights 
facility was the result of an in-depth review of the Company's North American 
production capabilities as part of a continuing effort to improve efficiency. 
Production from the Chicago Heights facility will be transferred to the 
Company's other U.S. facilities. This transition is expected to be completed 
and the facility closed over the next eighteen months.  The Company estimates 
savings at approximately $2,800,000 per year when completed. The Company's 
decision not to proceed further with the construction of the manufacturing 
facility in Thailand was influenced by the poor economic prospects for this 
joint venture and the level of additional investment that would have been 
required to complete the facility.  Refer to Note 14 of the Notes to the 
Consolidated Financial Statements.

RESULTS OF OPERATIONS 1998 VS. 1997   Net sales for 1998 were $454,930,000 
compared to $331,465,000 in the 1997, an increase of 37 percent.  
Acquisitions accounted for the entire increase.  Volume decreases in the 
Company's liquid coating resins business were offset by strong sales in the 
composite polymers and powder coating resins businesses. The Company expects 
that the continued global integration of its acquisitions, the introduction 
of new products, and expansion efforts will lead to improved performance in 
all of the Company's businesses in 1999.

The Company's gross profit margin was 16.3 percent in 1998 and 1997.  Margins
were favorably impacted by sales mix , internal process improvements, and raw
material price decreases.  This impact was offset by absorption issues in the
Company's liquid coating resins 

                                                                     10

<PAGE>

business resulting from lower than anticipated volumes. The Company expects 
raw material costs to continue to decrease in 1999 and internal process 
improvements to continue to favorably impact margins.

Operating expenses (research, selling, general and administrative) were 9.0 
percent of sales in 1998 compared to 7.9 percent of sales in 1997. The higher 
expenses compared to 1997 resulted primarily from the businesses acquired in 
1998 and 1997. 

Other expense in 1998 included pretax charges of $931,000, $4,650,000, and 
$2,617,000 for the relocation of the research and development facility, the 
closing of the Chicago Heights plant, and the write-off of the Thailand joint 
venture, respectively. In 1997, other expense included pretax charges of 
$811,000 for the relocation of the research and development facility and the 
write-off of a tax related receivable. Refer to Note 14 of the Notes to 
Consolidated Financial Statements.

Net interest expense was $7,737,000 in 1998 compared to $2,166,000 in 1997. 
This comparison reflects higher debt levels due to the acquisitions. 

The effective tax rate was 28.4 percent in 1998 and 38.3 percent in 1997.  
Tax rates in both years were affected by adjustments that reduced income tax 
expense as discussed in Note 8 of the Notes to Consolidated Financial 
Statements. Excluding these adjustments, the 1998 and 1997 tax rates were 
41.3 percent and 40.7 percent, respectively.  The 1998 rate was higher as a 
result of the nondeductibility of goodwill amortization related to the 
Syntech acquisition and foreign tax rate differential.  

Net income for 1998 was $15,752,000, or $1.52 per share, excluding net 
after-tax charges related to the nonrecurring items discussed in Note 14 of 
the Notes to Consolidated Financial Statements.  This represents a 3 percent 
increase in earnings per share over net income of $15,418,000, or $1.48 per 
share, for 1997. Including the nonrecurring items, net income for 1998 was 
$12,844,000, or $1.24 per share.

RESULTS OF OPERATIONS 1997 VS. 1996   Net sales for 1997 were $331,465,000 
compared to $315,925,000 in the 1996. The sales increase of 5 percent was 
made up of 4 percent from the acquisition of Syntech in August 1997 and a 
3 percent volume increase offset by a 2 percent price decrease. Volume 
increases in the Company's large national customers were offset by loss of 
low margin industrial toll business and delayed timing of inventory 
replenishments by certain customers. 

The Company's gross profit margin was 16.3 percent in 1997 compared to 15.4 
percent in 1996. The 1997 margins were favorably impacted by an increase of 
specialty products in the sales mix combined with the continuing focused 
efforts in the area of process improvements.

Operating expenses were 7.9 percent of sales in 1997 compared to 7.5 percent of
sales in 1996. The higher expenses compared to 1996 reflect higher headcount
levels, and the 

                                                                     11
<PAGE>

amortization of costs related to the acquisition of Syntech.

Other expense in 1997 included charges totaling $811,000, $.05 per share 
after taxes, for the estimated amount of employee termination benefits 
related to the relocation of the Minneapolis research and development 
facility to Carpentersville and the write-off of a tax related receivable.

Net interest expense was $2,166,000 in 1997 compared to $1,653,000 in 1996. 
This comparison reflects higher debt levels due to the acquisition of 
Syntech. Excluding the acquisition, interest expense in 1997 was impacted by 
a reduction in debt of approximately $7,500,000.

The effective tax rate was 38.3 percent in 1997 and 40.5 percent in 1996. The 
1997 tax rate reflects the tax benefit of an income tax audit of $591,000, or 
$.06 per share.

Net income in 1997 was $15,418,000, or $1.48 per share, compared to 
$13,833,000, or $1.32 per share, in 1996.  Excluding the acquisition of 
Syntech, net income for 1997 was $15,746,000, or $1.52 per share, which 
represents a 15 percent increase over 1996 earnings per share. 

FINANCIAL CONDITION   In 1998, operations generated cash of $23,696,000 
compared to $27,583,000 in 1997. The Company's current ratio was 1.5 at the 
end of 1998 compared to 1.3 at the end of 1997.  Working capital increased 
$10,580,000 primarily as a result of higher inventories and receivables in 
the U.S. and lower payables in Europe.   EBITDA increased to $42,087,000 in 
1998 from $37,502,000 in 1997, primarily as a result of the acquired 
businesses.  

Investing activities used cash of $82,320,000 in 1998 compared to $62,402,000 
in 1997 due to the 1998 acquisitions and increased capital expenditures.  
Capital expenditures were $25,663,000 in 1998 versus $11,203,000 in 1997. The 
1998 capital expenditures were primarily for the construction of the new 
research and development facility, powder capacity expansion, the 
implementation of an Enterprise Resource Planning (ERP) package, and 
productivity improvements. Capital spending for 1999 is expected to be 
approximately $30,000,000, primarily for the completion of the ERP project 
and capacity expansion for powder, solution acrylics, and composite polymers. 

Financing activities provided cash of $58,794,000 in 1998 compared to 
$37,688,000 in 1997. Total debt increased to $156,602,000 at October 31, 1998 
from $80,858,000 a year ago. The increase was primarily due to borrowings to 
fund acquisitions.  Debt as a percentage of invested capital increased to 
59.3 percent at October 31, 1998 from 46.9 percent a year ago as a result of 
the acquisitions.

The Board of Directors of the Company adopted a resolution in 1998 
authorizing the repurchase by the Company of up to an aggregate of 500,000 
shares of its common stock.  As 

                                                                     12

<PAGE>

of October 31, 1998, the Company had acquired 33,600 shares at a cost of 
$672,000. The resolution expires in May 1999.

The Company has a $150,000,000 unsecured revolving credit facility that 
terminates on July 30, 2002. At October 31, 1998, $26,653,000 was available 
under this facility. The Company's European subsidiaries, primarily the 
Italian subsidiary, have short-term lines of credit that are cancelable at 
any time of $28,591,000, of which $13,280,000 was available for future use at 
October 31, 1998.  These credit facilities and internally generated funds are 
expected to be adequate to finance McWhorter's capital expenditures and other 
operating requirements in 1999. Refer to Note 6 of the Notes to Consolidated 
Financial Statements for discussion of the Company's debt.

Refer to Note 9 of the Notes to Consolidated Financial Statements for 
discussion of environmental liabilities.  Refer to Note 1 of the Notes to 
Consolidated Financial Statements for a discussion of new accounting 
pronouncements.

YEAR 2000  During 1998, the Company continued its program to prepare its 
information technology (IT) and non-information technology (non-IT) systems 
for year 2000 compliance. The year 2000 issue relates to computer systems 
that use two digits rather than four to define the applicable year and 
whether such systems will properly process information when the year changes 
to 2000. 

The Company has completed an assessment of the impact of the year 2000 on its 
purchased and internally developed IT systems. The current purchased software 
and a majority of the internally developed software is year 2000 compliant. 
Non-compliant internally developed software is expected to be replaced by  
June 1999. The Company is currently in the process of modifying and testing 
its non-IT systems to ensure that these systems will function properly with 
respect to dates in the year 2000. The Company has begun formal 
communications with significant suppliers and customers to determine the 
extent to which the Company's activities would be impacted by those third 
parties' failure to remediate their own year 2000 issues.

The estimated costs related to testing and modifying existing systems for 
year 2000 compliance are approximately $300,000, of which $200,000 has been 
spent or committed to date. Approximately $100,000 of the total compliance 
costs are expected to be capital expenditures. No significant information 
systems projects have been deferred to accommodate the year 2000 issues.

Year 2000 compliance is expected to be achieved no later than June 1999. The 
Company believes that with the planned modifications, year 2000 issues will 
not have a material impact on operations. However, if these modifications are 
not made, or are not completed on a timely basis, year 2000 issues could 
result in the temporary inability to process orders, send invoices, or engage 
in similar business activities, which would have a material impact on the 
Company's operations. Failure by significant suppliers and customers to be 
year 2000 compliant could also have a material impact the Company.  The 
amounts of potential liability and lost revenue 

                                                                     13

<PAGE>

resulting from the failure to be year 2000 compliant cannot be reasonably 
estimated at this time.

The Company's contingency plans will be finalized as the testing of systems 
is completed. Contingency plans are expected to be completed by the first 
quarter of 1999 and will include the manual processes required to perform 
critical business functions that could be affected by year 2000 issues.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The Company is exposed to market risk from changes in interest rates, foreign 
exchange rates, and commodity prices.  

As of October 31, 1998, the Company does not use significant levels of 
derivative financial instruments to manage this risk.

The Company had $129,630,000 of long-term variable rate debt outstanding at 
October 31, 1998.  At this borrowing level, a hypothetical 10% adverse change 
in interest rates at October 31, 1998 would have a $750,000 unfavorable 
impact on the Company's pretax earnings and cash flows.  The primary interest 
rate exposures on floating rate debt are with respect to U.S. and European 
interbank rates. The majority of the Company's long-term obligations are 
variable rate debt. Therefore, the Company's exposure to changes in the fair 
value of its 

                                                                     14

<PAGE>

financial instruments is not significant.

The Company and its subsidiaries generally enter into transactions 
denominated in their respective functional currencies.  As a result, foreign 
currency exposures arising from transactions are not material to the Company. 
The primary foreign currency exposure arises from the translation of the 
Company's net equity investment in its foreign subsidiaries to U.S. dollars. 
The Company generally views as long-term its investments in foreign 
subsidiaries with functional currencies other than the U.S. dollar. The 
primary currencies to which the Company is exposed are the Italian lira and 
other European currencies. The fair value of the Company's net foreign 
investments would not be materially affected by a 10% adverse change in 
foreign currency exchange rates from October 31, 1998 levels.

The Company is a purchaser of certain commodity products which are procured 
at market prices established with the vendor at the time of purchase.  The 
Company does not use significant levels of commodity financial instruments to 
hedge commodity prices due to a high correlation between the commodity cost 
and the ultimate selling price of the Company's products.

                                                                     15

flows for each of the three years in the period ended October 31, 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 audits.

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

In our opinion, the financial statements referred to above present fairly, in 
all material respects, the consolidated financial position of McWhorter 
Technologies, Inc. and subsidiaries, at October 31, 1998 and 1997, and the 
consolidated results of their operations and their cash flows for each of the 
three years in the period ended October 31, 1998, in conformity with

                    NOTES TO FINANCIAL STATEMENTS


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BUSINESS   The Company operates in one business segment, the manufacture and 
distribution of resin and colorants used in coatings and composite polymer 
industries, and sells primarily to customers located in North America and 
Europe.

PRINCIPLES OF CONSOLIDATION   The consolidated financial statements include 
the accounts of the parent company and its subsidiaries.  Investments in 50 
percent or less owned companies and joint ventures are carried on the equity 
basis with the Company's share of earnings reflected as a component of other 
expense (income), net. All significant intercompany accounts and transactions 
are eliminated in consolidation.

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

INVENTORIES   Inventories are stated at the lower of cost or market. At 
October 31, 1998 and 1997 costs were recorded on the last-in, first-out 
(LIFO) method for approximately 63 percent and 76 percent of the inventories, 
respectively. Inventory costs not stated on the LIFO method are stated on the 
first in, first out (FIFO) method.

PROPERTY, PLANT AND EQUIPMENT   Property, plant and equipment are recorded at 
cost. Depreciation is based upon estimated useful lives of 10 to 40 years for 
buildings and 3 to 15 years for machinery and equipment, using the 
straight-line method.

INTANGIBLE ASSETS   Intangible assets are amortized using the straight line 
method over the estimated useful lives; 40 years for goodwill and 15 years 
for other intangible assets.  Goodwill represents the cost in excess of the 
fair value of net assets acquired in purchase transactions.

STOCK-BASED COMPENSATION   The Company accounts for stock-based compensation 
plans under the provisions of Accounting Principles Board Opinion (APB) No. 
25. Refer to Note 11 for disclosures required by Statement of Financial 
Accounting Standard (SFAS) No. 123, "Accounting for Stock-based Compensation".

EARNINGS PER SHARE   The Company adopted  SFAS No. 128, "Earnings Per Share" 
in 1998 which requires the disclosure of two earnings per share computations: 
basic and diluted. Earnings per share (EPS) is computed by dividing net 
income by the weighted average number of shares of stock (basic) plus stock 
equivalents (diluted) outstanding during the year.  Stock 

                                                                     22

<PAGE>

equivalents consist primarily of stock options and are included in the 
calculation of weighted average shares outstanding using the treasury stock 
method. EPS computations for prior years have been restated to reflect this 
new standard.

The basic weighted average shares reconciles to diluted weighted average 
shares as follows:

                                                   -----------------------------------
  Diluted weighted average shares outstanding      10,388,590   10,391,900  10,469,791
                                                   -----------------------------------
                                                   -----------------------------------
</TABLE>

Options to purchase 102,352 shares of common stock at a  weighted average 
option price of $25.13 per share were outstanding during 1998 but were not 
included in the computation of diluted earnings per share because the options 
exercise price was greater than the average market price of the common shares 
and, therefore, the effect would be antidilutive.

TRANSLATION OF FOREIGN CURRENCIES   Assets and liabilities of foreign 
subsidiaries are translated at the exchange rate in effect at the balance 
sheet date while the income and expenses are translated at the average 
exchange rates prevailing during the year. The related translation 
adjustments are reflected as a separate component of shareholders' equity. 
Gains and losses resulting from foreign currency transactions denominated in 
a currency other than the entity's functional currency are included in net 
income.

NEW ACCOUNTING PRONOUNCEMENTS   The Financial Accounting Standards Board 
(FASB) issued SFAS No. 130, "Reporting Comprehensive Income", SFAS No. 131, 
"Disclosures about Segments of an Enterprise and Related Information", and 
SFAS No. 132, "Employers' Disclosures about Pensions and Other Postretirement 
Benefits". SFAS No. 130 establishes standards for reporting and display of 
comprehensive income and its components. SFAS No. 131 establishes standards 
for reporting information about operating segments and related disclosures 
about products and services, geographic areas and major customers. SFAS No. 
132 revises current disclosure requirements for employers' pensions and other 
retiree benefits.  These standards are effective for fiscal years beginning 
after December 15, 1997.  These standards expand or modify current 
disclosures and, accordingly, will have no impact on the Company's reported 
financial position, results of operations, or cash flows.   The FASB also 
issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging 
Activities".  This standard is effective for fiscal years beginning after 
June 15, 1999.   As of October 31, 1998, the Company had no derivative 
instruments.  The Company adopted Statement of Position (SOP) 98-1 
"Accounting for the Costs of Computer Software Developed or Obtained for 
Internal Use" in 1998.  In accordance with SOP 98-1, internal and external 
costs incurred to develop internal use software are expensed during the 
preliminary project stage and capitalized during the application development 
stage and amortized over five to seven years.  Costs of computer software 
developed or obtained for internal use were immaterial in 1997 and 1996.

                                                                     23

NOTE 2 - ACQUISITIONS

In April 1998, the Company completed the acquisition of substantially all of 
the assets of Accurate for approximately $39,400,000 in cash and the 
assumption of $6,500,000 of debt.  Accurate, located in South Holland, 
Illinois, manufactures and distributes dispersed pigments for the coatings 
industry. The excess of the purchase price over the net book value of the 
assets was approximately $35,000,000, the largest component of which was 
allocated to goodwill.  In the first quarter of 1998, the Company purchased 
the equity interests of its joint venture partners in McWhorter Europe for 
approximately $8,200,000 in cash, which approximated the net book value of 
the identifiable assets. As a result, the Company increased its equity 
interest in McWhorter Europe from 33.3 percent to 100 percent.  Both 
acquisitions were accounted for using the purchase method and the results of 
the acquired companies have been included in the consolidated results of the 
Company from the dates of acquisition.  The finalization of the purchase 
price for both acquisitions is subject to completion.  The pro forma 
operating results including the acquired companies would not have been 
significantly different from the consolidated results of the Company.    

In August 1997, the Company completed the acquisition of Syntech for 
$48,300,000 in cash  and approximately $17,100,000 of assumed debt.  Syntech 
is an Italian based resin company with two production facilities in Italy and 
a joint venture in China.  The acquisition was accounted for using the 
purchase method.  The excess of purchase price over the net book value of 
identifiable assets was approximately $30,800,000, the largest component of 
which was allocated to goodwill. Syntech results since the date of 
acquisition are included in the consolidated results of the Company. The 
unaudited pro forma results  for 1997 and 1996 below reflect the purchase 
price accounting adjustments assuming the Syntech acquisition occurred at the 
beginning of each year presented.

Inventories stated at cost as determined by the LIFO method were 
approximately $905,000 and $2,276,000 lower at October 31, 1998 and 1997, 
respectively, than such costs determined under the FIFO method.  Compared to 
the FIFO method, the LIFO method increased (decreased) pretax income by 
$1,371,000, $(125,000), and $1,358,000 in 1998, 1997, and 1996, respectively, 
due to decreased (increased) raw material costs.  The related impact on 
earnings per share after taxes was $.08, $(.01), and $.08, in 1998, 1997, 
and 1996, respectively.

The Company has $150,000,000 available under a revolving credit facility that
enables the Company to borrow funds on an unsecured basis. Under the terms of
the agreement, interest rates are determined at the time of borrowing and are
based on London Interbank Offered Rates plus an applicable margin, including
facility fee, of up to .875 percent or other alternative rates.  The weighted
average interest rate at October 31, 1998 was 5.8 percent.  This facility
terminates on July 30, 2002.  At October 31, 1998, borrowings totaling
$123,347,000 were outstanding under this agreement, all of which were classified
with long-term debt as they are supported by the long-term credit facility and
will continue to be refinanced beyond October 31, 1999.  The weighted average
interest rate at October 31, 1998 for the variable rate note payable and
variable rate mortgage loans was 3.90 percent and 6.56 percent, respectively.
The mortgage loans are guaranteed by mortgages on certain property and
equipment.

The aggregate payments of long-term debt outstanding for the next five years and
thereafter, excluding revolving credit borrowings, are $1,163,000 in 1999,
$1,145,000 in 2000, $5,127,000 in 2001, $212,000 in 2002, $113,000 in 2003, and
$184,000 thereafter.

In addition, the Company had $10,000,000 outstanding at October 31, 1998, under
an overnight credit facility with a weighted average interest rate of 5.93
percent. The Company's European subsidiaries, primarily its Italian subsidiary,
have short-term lines of credit that are cancelable at any time of $28,591,000,
at a weighted average interest rate at October 31, 1998 of 4.90 percent, of
which $15,311,000 was outstanding at October 31, 1998.

Interest paid during 1998, 1997, and 1996 was $6,950,000, $2,146,000, and
$1,725,000, respectively.  At October 31, 1998,  the Company had $4,307,000 in
unissued letters of credit. The carrying value of the Company's debt
approximates fair value at October 31, 1998.

1998 results included a reduction in income tax expense of $2,311,000, $.22 per
share, relating to the impact on deferred income taxes of changes in the Italian
income tax regulations and rates.  1997 results included a reduction in income
tax expense of $591,000, $.06 per share, that resulted from the conclusion of an
income tax audit for the period prior to the Company's spin-off from The Valspar
Corporation.

NOTE 9- ENVIRONMENTAL LIABILITIES

With respect to environmental liabilities, management reviews each individual
site, taking into consideration the numerous factors that influence the costs
that will likely be incurred.  Based on these reviews, McWhorter accrues for
potential environmental liabilities.  Reserves are adjusted as additional
information becomes available to better estimate the total remediation costs at
individual sites. While uncertainties exist with respect to the amounts and
timing of McWhorter's ultimate environmental liabilities, management believes
that such costs, individually and in the aggregate, will not have a material
adverse effect on the Company's financial condition or results of operations.

Relating to Company plants located in Philadelphia, Pennsylvania; Portland,
Oregon; Carpentersville, Illinois; and Italy; the Company has been named a
potentially responsible party for the remediation of independently operated
waste disposal sites previously used by these plants.

At October 31, 1998 the estimated amount of probable environmental liability of
the Company is approximately  $3,420,000. Cargill Incorporated has agreed to
indemnify the Company, subject to certain limitations, for damages resulting
from environmental matters relating to its former Resin Products Division that
was acquired by the Company in 1994.  Indemnification for environmental
liabilities, subject to certain limitations, related to the Italian facilities
is provided for under the escrow provisions of the Syntech acquisition
agreement.  As a result of the probable recoveries of $2,722,000 under the
indemnification agreements above, the Company's net estimated environmental
liability is approximately $698,000.

NOTE  10- RETIREMENT BENEFIT PROGRAMS

In February 1994, McWhorter adopted an Employee Stock Ownership Plan (ESOP) and
an Employee Savings Plan (ESP).  These primary retirement benefit programs are
defined contribution plans covering the majority of the employees in the U.S.
The total costs of the ESOP were $1,158,000, $1,557,000, and $1,556,000 in 1998,
1997, and 1996, respectively.  The total costs of the ESP were $575,000,
$568,000, and $515,000 in 1998, 1997, and 1996, respectively.  Contributions are
made to the ESOP at the rate of 4 percent of each participant's compensation and
additional contributions can be made at the Company's discretion.  Contributions
to the ESP are based on a percentage of each employee's contributions to the
plan.

The Company sponsors defined benefit plans for certain hourly employees in the
U.S. and for its employees at the European locations.  The related pension costs
and obligations are not material.

The Company also has a nonqualified deferred compensation plan which permits key
employees to defer certain portions of their compensation.  Such compensation is
fully vested at the time of the contribution.  The Company can also make
discretionary contributions to the 

                                                                            29

<PAGE>

plan which vest upon the completion of 5 years employment. Deferred 
compensation liability at the end of 1998 was $974,000 of which $396,000 is 
required to be settled by a fixed number of shares of the Company's common 
stock.  The Company established an irrevocable rabbi trust in 1997 to fund 
this plan. The value of the assets, excluding shares of the Company's stock, 
in the trust at October 31, 1998 was $357,000.  The shares of the Company's 
stock in the trust are classified as treasury stock and the associated 
liability of $396,000 is classified as other within the shareholders' equity.

The Company accrues for its Italian employees' benefits in accordance with
Italian statutes.  Such benefits are based on length of service, employment
category, and remuneration and are payable when an employee leaves the Company.
The liability  as of October 31, 1998 and 1997 of $2,307,000 and $2,015,000,
respectively, is the amount to which the employee is entitled for services
rendered to date.  Amounts charged to expense in 1998 and 1997 were $363,000 and
$52,000, respectively.

NOTE 11- STOCK PLANS

The Company's two stock incentive plans adopted in 1994 and 1996 provide for the
granting of options and the issuance of restricted stock, deferred stock and
stock appreciation rights of up to 1,050,000 shares of common stock, of which
276,302 shares are available for future grants. Options issued to date under
these plans have a term of ten years and become fully vested over a period of up
to five years.  Outstanding options will expire over a period ending no later
than June 1, 2008.  A summary of stock option activity for the 1994 and 1996
Stock Incentive Plans follows:

Under APB No. 25, because the exercise price of the Company's employee stock
options equals the market price of the underlying stock on the date of grant, no
compensation expense is recognized. The impact on 1998, 1997 and 1996 net income
and earnings per share under the fair value method required by SFAS No. 123
would have been immaterial based upon fair value at the date of grant for awards
granted in 1998, 1997, and 1996.  The weighted average fair value for the 1998,
1997, and 1996 option grants was $8.01, $7.33, and $4.95, respectively.  The
fair value at the date of grant was determined using the Black-Scholes option
pricing model with the assumptions below.  In management's opinion, the
Company's employee stock options have characteristics significantly different
from those of traded options, and because changes in the subjective input
assumptions can materially affect the fair value estimate, the existing models
do not provide a reliable single measure of the value of the employee stock
options.

Restricted stock performance awards have been granted to key officers under the
1994 plan. These restricted stock awards will vest only if the Company achieves
certain financial goals over a five-year performance period.  Restricted shares
granted under the plan were 3,800 in 1998 at a market value of $24.81 per share;
7,493 in 1997 at market value of $22.75 per share; and 94,354 in 1995 at a
market value of $15.50 per share.  The awards were recorded at the market value
of the shares at the time the shares were awarded. The total market value of the
shares will be charged to compensation expense based on achievement of the
related financial goals.  After comparing the Company's performance to the
financial goals, $250,000 was charged to expense in 1998, 1997 and 1996.

                                                                            31

The Company also issued 2,500, 1,500, and 1,483 restricted and deferred shares
in 1998, 1997 and 1996, respectively, with vesting periods of up to three years.
Amounts charged to expense were $4,000 in 1998, $30,000 in 1997, and $22,000 in
1996.

In 1996 the Company established the 1996 Non-employee Director Stock Option and
Award Plan (the 1996 Directors' Plan).  The 1996 Directors' Plan provides for
the issuance of up to 50,000 shares of the Company's common stock of which
36,231 shares are available for future grants.  Participation in the 1996
Directors' Plan is limited to members of the Board of Directors of the Company
who are not salaried officers or employees of the Company or any of its direct
or indirect subsidiaries.  Deferred stock awards granted under this plan were
3,884, 3,814 and 6,071 in 1998, 1997 and 1996, respectively, and amounts charged
to expense were $93,000, $93,000 and $110,000 in 1998, 1997, and 1996,
respectively.

Each outstanding common share includes a right to purchase one one-hundredth
share of Series A Junior Preferred Participating Stock (Preferred Stock) under
certain circumstances.  Until exercisable, the rights are not separable from the
underlying common shares.  The rights only become exercisable if a person or
group (an acquiring person) acquires, or makes an offer to acquire, 15 percent
or more of the Company's common stock without the prior approval of the
Company's Board of Directors.  The exercise price of each right is $70.  If
someone becomes an acquiring person, the holder of each right (other than the
acquiring person) will be entitled to purchase common stock of the Company
having a value of twice the exercise price of the right.  In addition, if the
Company is acquired in a transaction in which the Company's common stock is
exchanged for cash or securities or more than 50 percent of its consolidated
assets or earnings power are sold, each holder (other than the acquiring person)
will have the right to purchase common stock of the acquiring company having a
market value of twice the exercise price of the right.  The rights may be
redeemed by the Company at the price of $.01 per right at any time prior to
anyone becoming an acquiring person.  150,000 shares of Preferred Stock are
reserved for issuance upon the exercise of the rights.  The Preferred Stock is
nonredeemable, with a $100 liquidation preference and 100 votes per share, and
is entitled to 100 times the per share dividends on the common stock.

NOTE 12- CONTINGENCIES

The Company is involved in various legal actions arising in the normal course of
business.  Management, after taking into consideration legal counsel's
evaluation of such actions, is of the opinion that the outcome of these matters
will not have a material adverse effect on the Company's financial position.

NOTE 13- GEOGRAPHIC SEGMENTS INFORMATION

The Company's operations include foreign subsidiaries beginning in August 1997.
Prior to that, all the Company's facilities were in the U. S.  Inter-geographic
sales are not significant.  The Company operates facilities in the U. S. and
Europe.  Sales, operating income, and identifiable assets for the European
operations in 1998 were 26 percent, 25 percent, and 37 

                                                                            32

percent of the consolidated totals, respectively.  In 1997, the comparable 
percentages were 3 percent, 3 percent, and 35 percent of the consolidated 
totals.

NOTE 14- NONRECURRING ITEMS

Fourth quarter 1998 expense (income), net included charges of $4,650,000, $.27
per share after taxes, related to the planned closure of the Chicago Heights,
Illinois facility, and $2,617,000, $.15 per share after taxes, related to the
write-off of the investment in the McWhorter Thailand joint venture.  Third
quarter 1998  other expense (income), net included a charge of $931,000, $.05
per share after taxes, related to the relocation of the research  and
development facility from Minneapolis to Carpentersville.  Second quarter 1998
cost of sales included a charge of $500,000, $.03 per share after taxes, related
to the one-time write-off of the excess of fair value over net book value
associated with inventories acquired as part of the purchase of Accurate.  1997
other expense (income), net includes a second quarter charge of $811,000, $.05
per share after taxes, related to costs, primarily severance, for the research
and development facility relocation and the write-off of a tax related
receivable.  As discussed in Note 8 of the Notes to Consolidated Financial
Statements, 1998 second quarter and 1997 second quarter were impacted by
reduction in income tax expense of $2,311,000, $.22 per share, and $591,000,
$.06 per share, respectively.

The planned closure of the Chicago Heights facility is the result of an in-depth
review of the Company's North American production capabilities as part of a
continuing effort to improve efficiency.  Production from the Chicago Heights
facility will be transferred to the Company's other U.S. facilities.
Approximately 36 employees will be impacted by the closing.  The 1998 charge for
the Chicago Heights facility closing is composed of approximately $4,240,000 for
the write-down of plant and equipment with a carrying value of $4,800,000 to
their fair value and approximately $410,000 for severance and other exit costs.
The write-down for the plant and equipment reflects impairment in their carrying
value because the gross undiscounted future cash flows to be generated by the
assets were less than the carrying value.  The fair value of the plant and
equipment was based on the estimated future cash flows to be generated by the
facility.  The Company's decision not to proceed further with the construction
of the manufacturing facility in Thailand was influenced by the poor economic
prospects for this joint venture and the level of additional investment that
would have been required to complete the facility.

                               FIDUCIARY RESPONSIBILITY


          The plan administrator, the trustee, any investment manager appointed
pursuant to paragraph III-4, and any other fiduciaries with respect to the plan
or trust shall discharge their duties thereunder solely in the interest of
participants and beneficiaries, for the exclusive purpose of providing their
benefits and defraying reasonable expenses of plan and trust administration,
with the care, skill, prudence and diligence under the circumstances then
prevailing that a prudent man acting in a like capacity and familiar with such
matters would use in the conduct of an enterprise of a like character and with
like aims.


                                     ARTICLE III

                        THE TRUST FUND AND ITS ADMINISTRATION


          III-1.  THE TRUST FUND.  The "trust fund" as at any date means all
property then held by the trustee under this agreement.


          III-2.  PLAN ADMINISTRATOR.  The plan is administered by an
Administrative Committee (the "plan administrator"), appointed by the company
pursuant to the plan.  Benefits payable under the plan are distributed by the
trustee as directed by the plan administrator.  The company will certify to the
trustee from time to time the person or persons appointed as members of the plan
administrator.  The trustee may rely on the latest certificate received without
further inquiry or verification.


          III-3.  GENERAL POWERS.  The trustee shall have exclusive authority
and discretion to manage and control the trust fund except to the extent that
authority to manage investments has been allocated to one or more investment
managers pursuant to paragraph III-4, to the administrator pursuant to paragraph
III-3(r), paragraph III-3(s), paragraph III-3(t) or paragraph IV-4, or to
participants pursuant to paragraph IV-5.  The trustee shall have the following
powers, rights and duties in addition to those provided elsewhere in this
agreement, the plan or by law:

          (a)  To manage, sell, contract to sell, grant options to
               purchase, convey, exchange, transfer, abandon, improve,
               repair, insure, lease for any term (although commencing in


                                     -2-
<PAGE>


               the future or extending beyond the term of this trust) and
               otherwise deal with all property, real or personal, in such
               way, for such considerations, and on such terms and
               conditions as the trustee decides.

          (b)  To retain in cash such amounts as the trustee considers
               advisable and as are permitted by applicable law; and to
               invest and reinvest part or all of the balance of the trust
               fund in stocks, bonds, notes, mortgages, mutual fund shares
               or other property of any kind, real or personal, and to
               diversify such investments so as to minimize the risk of
               large losses, unless under the circumstances it is clearly
               prudent not to do so.

          (c)  To deposit cash in any depositary (including the banking
               department of the bank acting as trustee or any affiliate of
               the bank acting as trustee) without liability for interest
               and, without limiting the generality of the foregoing, to
               invest cash in savings accounts or time certificates of
               deposits bearing a reasonable rate of interest in the
               banking department of the bank acting as trustee or any
               affiliate of the bank acting as trustee.

          (d)  To make any payment or distribution from the trust fund as
               directed by the plan administrator without inquiring as to
               whether a payee or distributee is entitled thereto or as to
               whether it is proper, and the trustee shall not be liable
               for a payment or distribution made as directed by the plan
               administrator without notice or knowledge that the payment
               or distribution is not proper under the terms of the plan or
               this agreement; and to notify the plan administrator if a
               payment or distribution is returned to the trustee, and the
               trustee shall have no obligation to search for or ascertain
               the whereabouts of a payee or distributee.

          (e)  To the extent permitted by law, to borrow from anyone, with
               the company"s approval, such sum or sums from time to time
               as the trustee considers desirable to carry out this trust,
               and to mortgage or pledge all or part of the trust fund as
               security, provided that the trustee shall not borrow to
               acquire employer securities as described in paragraph 


                                     -3-
<PAGE>


               IV-4, or pledge employer securities held under the trust as
               security for any loan.

          (f)  To retain any funds or property subject to any dispute
               without liability for interest and to decline to make
               payment or delivery thereof until final adjudication by a
               court of competent jurisdiction or until an appropriate
               release is obtained.

          (g)  To begin, maintain or defend any litigation necessary in
               connection with the administration of the plan or this
               trust, except that, unless otherwise required by law, the
               trustee shall not be obliged or required to do so unless
               indemnified to the trustee"s satisfaction.

          (h)  With the consent of the company or the plan administrator,

               demands.

          (i)  Except as provided in paragraph IV-4 with respect to
               employer securities, to give proxies to vote stocks and
               other voting securities, to join in or oppose (alone or
               jointly with others) voting trusts, mergers, consolidations,
               foreclosures, reorganizations, liquidations, or other
               changes in the financial structure of any corporation, and
               to exercise or sell stock subscription or conversion rights.

          (j)  To hold securities or other property in the name of a
               nominee, in a depositary, or in any other way, with or
               without disclosing the trust relationship; provided,
               however, that except as authorized by regulations issued by
               the Secretary of Labor, the indicia of ownership of the
               assets of the trust fund shall not be maintained outside the
               jurisdiction of the district courts of the United States.

          (k)  Except as provided in paragraph IV-4 with respect to certain
               employer securities, to report to the employers and the plan
               administrator on each accounting date under the plan, or as
               soon thereafter as practicable, or at such other times as
               the employer may request, the then net worth of the trust
               fund (that is, the fair market value of the trust fund, less
               liabilities, if any, other than 


                                     -4-
<PAGE>


               liabilities to persons entitled to benefits under the plan)
               determined on the basis of such evidence, data or information
               as the trustee considers pertinent and reliable.

          (l)  To furnish to the employers and the administrator an annual
               account, or an account for such other period as the plan
               administrator may specify or as may be required under this
               agreement or the plan, on an accrual basis showing all
               investments, receipts, disbursements, and other transactions
               involving the trust during the account period, and also
               showing the assets of the trust fund held at the end of the
               period.  Upon the expiration of ninety (90) days from the
               date of filing such account, the trustee shall be forever
               released and discharged from all liability and
               accountability to the plan administrator with respect to the
               accuracy of such accounting and the propriety of all acts
               and failures to act of the trustee reflected in such account
               for which it shall be responsible hereunder, except with
               respect to any such acts or transactions as to which the
               plan administrator shall within such 90 day period file with
               the trustee specific written objections.

          (m)  To pay any estate, inheritance, income or other tax, charge
               or assessment attributable to any benefit payable under the
               plan out of such benefit after giving the employers and the
               plan administrator notice as far in advance as practicable
               (except that mandatory federal or state withholding of
               income tax may be made without such notice); to defer making
               payment of any such tax, charge or assessment if it is
               indemnified to its satisfaction in the premises; and to
               require before making any payment such release or other
               document from any lawful taxing authority and such indemnity
               from the intended payee as the trustee considers necessary
               for its protection.

          (n)  To maintain records and accounts reflecting all receipts and
               disbursements under this agreement and such other records
               and accounts as the plan administrator may specify, all of
               which shall be open to the inspection of the employers or
               the plan administrator at all reasonable times, and may be
               audited from


                                     -5-
<PAGE>


               time to time by anyone named by the employer or plan 
               administrator.

          (o)  To employ agents, attorneys, accountants or other persons
               (who also may be employed by the employer) and to delegate
               to them such powers as the trustee considers desirable
               (except that the trustee may not delegate its
               responsibilities as to the management or control of the
               assets of the trust fund), provided that such delegation,
               and the acceptance thereof, by such agents, attorneys,
               accountants or other persons, shall be in writing; and, to
               the extent permitted by law, the trustee shall be protected
               in acting or refraining from acting on the advice of persons
               so employed without court action.

          (p)  To appoint a bank, trust company, or broker or dealer
               registered under the Securities Exchange Act of 1934 to act
               as custodian with respect to any portion of the trust fund;
               and a custodian so appointed shall have custody of such
               assets as are deposited with it and as custodian such
               rights, powers and duties with respect thereto as shall be
               agreed upon from time to time by the trustee and such
               custodian.

          (q)  When directed by the plan administrator, to make loans to
               participants under the plan from the trust fund in an amount
               or amounts specified by the plan administrator without
               inquiring as to whether a participant is entitled to such a
               loan or as to whether the loan is proper under the terms of
               the plan or under any applicable state or federal law.

          (r)  When directed by the plan administrator or an investment
               manager, to apply for and invest all or any part of the
               assets of the trust fund in one or more guaranteed
               investment contracts issued by one or more legal reserve
               life insurance companies legally authorized to issue such
               contracts in the state of Illinois, which contracts shall
               provide for a guarantee as to principal and interest.  The
               plan administrator or an investment manager may direct the
               trustee to accept and retain any insurance contracts
               transferred to the trust from any insurance company or other
               contract holders.  The trustee may be 


                                     -6-
<PAGE>


               designated as the contract holder under any such insurance 
               contracts, but any action required or permitted to be taken by 
               the trustee as contract holder shall be taken only in 
               accordance with the directions of the plan administrator or 
               the investment manager.  The trustee may delegate to the plan 
               administrator or the investment manager any or all of its 
               duties as contract holder under any contract.  The trustee 
               shall have no duty to question the propriety of any direction 
               of the plan administrator or any investment manager, and shall 
               incur no liability for any action taken pursuant to such 
               direction or for any failure to act in the absence of such 
               direction, nor shall the trustee be obligated to inquire into 
               the terms and conditions of any insurance contract purchased

               plan administrator or an investment manager, or to purchase

               authorized to issue such contracts in the state of Illinois.

          (u)  To furnish the plan administrator with such information in

               intended to meet the requirements of Section 401(a) of the
               Internal Revenue Code; and to allocate, credit and
               distribute any such funds and other property so transferred

          (y)  To transfer an eligible rollover distribution described in
               Section 402(c)(4) of the Internal Revenue Code directly to
               an eligible retirement plan described in Section
               402(c)(8)(B) of the Internal Revenue Code, as directed by
               the plan administrator.


          III-4.  INVESTMENT MANAGERS.  The plan administrator may appoint one
or more investment managers for the purpose of directing the investment of part
or all of the assets of the trust fund.  Except as otherwise provided by law,
the trustee shall have no obligation for investment of any assets of the trust
fund that are subject to management by an investment manager.  Appointment of an
investment manager shall be made by written notice to the investment manager and
the trustee, which notice shall specify those powers, rights and duties of the
trustee under this agreement that are allocated to the investment manager and
that portion of the assets of the trust fund subject to investment management.
An investment manager so appointed pursuant to this paragraph shall be either a
registered investment adviser under the Investment Advisers Act of 1940, a bank,
as defined in said Act, or an insurance company qualified to manage, acquire and
dispose of the assets of the plan under the laws of more than one state of the
United States.  Any such investment manager shall acknowledge to the plan
administrator in writing that it accepts such appointment and that it is a
fiduciary with respect to the plan and trust.  An investment manager may resign
at any time upon written notice to the trustee and the employer.  The plan
administrator may remove an investment manager at any time by written notice to
the investment manager and the trustee.


          III-5.  COMPENSATION AND EXPENSES.  Except as otherwise provided below
in this agreement, all reasonable costs, charges and expenses incurred in the
administration of this trust and the plan, including compensation to the trustee
(as agreed upon 


                                     -8-
<PAGE>


between the employer and the trustee), compensation to an investment manager 
(as agreed upon between the employer and the investment manager), and any 
compensation to agents, attorneys, accountants and other persons employed by 
the trustee or the plan administrator, will be paid from the trust fund to 
the extent such costs and expenses are not paid by the employers in such 
proportions as the company directs.  Expenses incurred in connection with the 
sale, investment and reinvestment of the trust fund (such as brokerage, 
postage, express and insurance charges and transfer taxes) shall be paid from 
the trust fund.

          III-6.  LIMIT OF TRUSTEE"S RESPONSIBILITY.  No power, duty or
responsibility is imposed upon the trustee under the plan, except as set forth
in this agreement or the plan.  Until they determine or are advised to the
contrary, the trustee and any investment manager (appointed as provided in
paragraph III-5) may assume that this trust is qualified under Section 401(a),
and is entitled to tax exemption under Section 501(a), of the Internal Revenue
Code of 1986.


          III-7.  COMMON FUND.  If more than one employer has adopted the plan,
the trustee shall not be required to make any separate investment of the trust
fund for the account of the plan as applied to the several employers and may
administer and invest all contributions made under the plan as one trust fund.
If, for any purpose, it becomes necessary to determine as of any date the
portion of the trust fund allocable to all or any group of participants employed
by any one of the employers, such portion shall be determined by the plan
administrator, taking into consideration the relative aggregate employer
contributions to the trust fund with respect to such participants, the relative
aggregate benefits paid and payable from the trust fund to or on behalf of such
participants, and such other factors as the plan administrator deems
appropriate.  Any such determination by the plan administrator shall be binding
upon all of the employers, participants and all other persons.  The trustee will
have no duty or responsibility to question any determination or direction by the
plan administrator under this paragraph III-7.


          III-8.  LOANS.  The plan administrator shall be the named fiduciary
exclusively responsible for the administration of the participant loan program
pursuant to the terms of the plan, including responsibility for issuing and
maintaining custody of promissory notes and other documentation pertaining to
such loans, and for all related loan disclosure and recordkeeping matters.  Loan
payments shall be collected by the plan administrator and remitted to the
trustee, who shall invest such repayments among the investment funds in the
proportions directed by the plan administrator.  Promissory notes held by the
plan administrator shall not be included as assets of the trust fund 


                                     -9-
<PAGE>


for purposes of the reports and accounts furnished by the trustee.  The 
trustee shall not be liable for any actions taken by the plan administrator 
under this paragraph.

                                      ARTICLE IV

                                  TRUST INVESTMENTS

          IV-1.  INVESTMENT BY TRUSTEE.  Except to the extent that an 
investment manager has been appointed, except to the extent the trustee is 
directed to invest in guaranteed investment contracts under subparagraph 
III-3(r), in mutual funds or individual securities under subparagraph 
III-3(s), in group annuity deposit administration or separate account 
contracts under subparagraph III-3(t), or in employer securities under 
paragraph IV-4, and except to the extent that participants direct investments 
among investment funds under paragraph IV-5, the trustee shall have the sole 
investment responsibility with respect to the assets of the trust fund, and 
the trustee shall have the sole and exclusive authority and discretion to 
manage, acquire, dispose and control such assets of the trust fund and may 
invest and reinvest any portion or all of such assets in stocks, bonds, 
notes, mortgages, mutual fund shares or other property of any kind, real or 
personal.

          IV-2.  INVESTMENT MANAGER-DIRECTED INVESTMENT. If the plan
administrator has appointed an investment manager pursuant to paragraph III-4 of
the trust, such investment manager shall have sole and exclusive authority and
discretion to direct the trustee as to the investment of part or all of the
assets of the trust fund and, except as provided by law, the trustee shall have
no obligation with respect to the investment of such plan assets.


          IV-3.  INVESTMENT FUNDS.  If the plan administrator has authorized the
establishment of investment funds under the plan, the plan administrator shall
decide which investment funds shall be offered under the plan and the employer
shall establish written guidelines and objectives for each fund under the plan.
Examples of investment funds include a fixed income fund, an equity fund, a fund
consisting of mutual funds selected by the plan administrator or an investment
manager, and a employer stock fund designed to invest primarily in employer
securities, as described in paragraph IV-4.  The trustee will invest
contributions and account balances among the investment funds in the proportions
directed by the plan administrator, but shall have no duty to verify such
directions and shall not be responsible for any loss that results from following
such directions.  The trustee may, upon at least 30 days" advance written notice
to the employer, terminate an existing investment fund or funds.

          IV-4.  EMPLOYER SECURITIES.  The plan administrator may direct the
trustee to invest all or any part of the assets of an investment fund in
employer securities, in accordance with the following provisions:

          (a)  The term "employer security" means stock that is a
               qualifying employer security (as defined in Section
               407(d)(5) of the Employee Retirement Income Security Act of
               1974 ("ERISA")) issued by an employer of employees covered
               by the plan, or by an affiliate of such employer.

          (b)  The plan administrator may direct the trustee to invest any
               portion of the assets of the trust fund (other than assets
               under the control of an investment manager appointed under
               paragraph III-4) in employer securities, may direct the
               trustee to sell any such securities held as an asset of the
               trust fund and may direct the trustee to accept a
               contribution from an employer in the form of employer
               securities; provided that, all such purchases and sales
               shall be for adequate consideration (as defined in Section
               3(18) of ERISA) and shall meet the requirements exempting
               such transactions from the prohibited transaction provisions
               of ERISA and the Internal Revenue Code.  Adequate
               consideration means:  in the case of a security for which
               there is a generally recognized market, either (i) the price
               of the security prevailing on a national securities exchange
               that is registered under Section 6 of the Securities
               Exchange Act of 1934, or (ii) if the security is not traded
               on such a national securities exchange, a price not less
               favorable to the plan than the offering price for the
               security as established by the current bid and asked prices
               quoted by persons independent of the issuer and of any party
               in interest (as defined in Section 3(14) of ERISA); and in
               the case of an employer security (including an employer
               security acquired directly from the issuer) other than a
               security for which there is a generally recognized market,
               the fair market value of such security as determined in good
               faith by the plan administrator pursuant to the terms of the
               plan and in accordance with applicable law.  The trustee
               will not undertake to value or be responsible for the
               valuation of employer 


                                     -11-
<PAGE>


               securities not traded on a national securities exchange.
               The trustee shall not be required to hire an independent
               valuation firm to value employer securities not traded on a
               national securities exchange.  The trustee may rely on any
               valuation figure supplied by the plan administrator or the
               opinion of an independent valuation firm hired by the plan
               administrator, but shall have no duty to verify such opinion
               or valuation figure and shall not be responsible for any loss
               that results from reliance upon such opinion or valuation 
               figure.  The trustee may, in its sole discretion, direct the
               plan administrator to obtain an opinion of an independent 
               valuation firm or may require that an additional valuation be
               obtained.

          (c)  If securities issued by an employer are acquired from or
               sold to a party in interest, no commission shall be charged
               to the trust fund with respect to such acquisition or sale.

          (d)  Directions to be given or furnished by the plan
               administrator to the trustee in accordance with the
               provisions of this paragraph shall be in writing or such
               other form of communication as is mutually acceptable to the
               plan administrator and the trustee.  Absent any direction by
               the plan administrator, the trustee shall have no obligation
               or responsibility to acquire or sell any employer securities
               pursuant to the provisions of this paragraph and may invest
               any assets of the trust fund without regard to this
               paragraph.

          (e)  The trustee shall not exercise any voting rights with
               respect to the securities of an employer unless directed by
               the plan administrator and shall not be liable for the
               voting of such securities, the failure to vote such
               securities if not directed by the plan administrator or the
               direct or indirect results of such voting or failure to
               vote.  The plan administrator shall direct the trustee with
               respect to the exercise of stock subscription rights,
               conversion rights, warrants, options, tender offers,
               buy-sell arrangements and other rights or duties with
               respect to employer securities held by the 


                                     -12-
<PAGE>


               trust fund.  The plan administrator also shall direct the 
               trustee with respect to the disposition of any dividend 
               income related to the employer securities held under the 
               trust fund.

          (f)  The plan administrator shall determine whether the employer
               securities purchased by the trust fund must be registered or
               must comply with any provision of the Securities Act of 1933
               (the "Act") or any other state or federal law governing or
               pertaining to securities.  If the plan administrator
               determines that such registration or other action is
               necessary, the plan administrator shall complete and file a
               Registration Statement under the Act or such other
               documentation as is required by applicable state or federal
               law.


          IV-5.  TRUSTEE"S INVESTMENT OF AMOUNTS SUBJECT TO PARTICIPANT
INVESTMENT DIRECTION.  If the plan administrator has specified that participants
may individually direct the investment of their accounts, the trustee shall,
upon written direction from a participant given in accordance with the terms of
the plan, invest and reinvest amounts credited to such participant"s account as
directed by the participant subject to the following:

          (a)  The trustee, except as otherwise provided below, shall make
               purchases, pledges or sales of any property for a
               participant"s accounts only as the participant directs in
               writing and the trustee shall be under no obligation to
               inquire as to the propriety of or the amount of any
               investment direction of a participant.

          (b)  The trustee shall have the power to invest any portion of
               the assets in a participant"s investment account that is
               held in cash or cash equivalents in short term, fixed income
               investments pending receipt of instructions from the
               participant regarding the investment of his accounts.

          (c)  Each participant shall indemnify and hold the trustee and
               the employer harmless for any losses suffered as a result of
               investments and reinvestments made by the trustee in good
               faith reliance upon any investment direction given by such
               participant in accordance with 


                                     -13-
<PAGE>


               this paragraph IV-5 and the terms of the plan.

          (d)  The trustee shall have the power, right and duty to
               determine and report to the plan administrator, at such
               times as the plan administrator and the trustee shall agree
               upon, the fair market value (as determined in the sole
               discretion of the trustee) of the assets held for the
               benefit of each participant in accordance with this
               paragraph IV-5.  The trustee shall have the right to rely on
               valuations prepared by third parties as to assets held by
               any such third party.

          (e)  The trustee shall have the power, right and duty to provide
               to the plan administrator on each accounting date or as soon
               thereafter as practicable a statement showing the assets
               held for the benefit of each participant in accordance with
               this paragraph IV-5 and any expenses attributable to the
               acquisition and maintenance of such assets and expenses
               attributable to any assets disposed of since the last
               preceding accounting date.

          (f)  On the written direction of a participant, given in
               accordance with the plan, the trustee shall liquidate for
               their fair market value (as determined by the trustee after
               consulting with the participant) all of the assets held for
               the benefit of the participant in accordance with this
               paragraph IV-5 and credit to such participant"s accounts
               under the plan the amount realized on such liquidation.

          (g)  Notwithstanding paragraph III-5, all expenses incurred in
               connection with the sale, investment and reinvestment of
               assets in accordance with this paragraph IV-5 (such as
               custodial, maintenance, investment manager, brokerage,
               postage, express and insurance charges and transfer taxes)
               shall be charged to the appropriate accounts of a
               participant.

          (h)  If required by law, the trustee reserves the right to
               disapprove any investment direction filed with the trustee.

          (i)  Except to the extent otherwise required by law, the trustee
               is not liable or responsible for any loss resulting to
               accounts by reason


                                     -14-
<PAGE>


               of any investment or reinvestment made by the trustee at the 
               direction of a participant, and, therefore, the trustee is 
               relieved of any duty to review from time to time such property
               included in a participant"s investment accounts.


                                      ARTICLE V

                                  GENERAL PROVISIONS


          V-1.  ACTION BY EMPLOYERS.  Any action required or permitted to be
taken by an employer under the trust shall be by resolution of its Board of
Directors, by resolution of a duly authorized committee of its Board of
Directors, or by a person or persons authorized by resolution of its Board of
Directors or such committee.

          V-2.  WARRANTY.  The employer warrants that all directions or
authorizations by it or the plan administrator, whether for the payment of money
or otherwise, will comply with the plan and this trust.

          V-3.  DISAGREEMENT AS TO ACTS.  If there is a disagreement between the
trustee and anyone as to any act or transaction reported in any accounting, the
trustee shall have the right to a settlement of its account by any proper court.

          V-4.  COURTS.  Except as otherwise provided by law, in case of any
court proceedings involving an employer, the plan administrator, the trustee or
the trust fund, only the employer or the plan administrator, as the case may be,
and the trustee shall be necessary parties to the proceedings, and no other
person shall be entitled to notice of process.  A final judgment entered in any
such proceedings shall be conclusive.

          V-5.  EVIDENCE.  Evidence required of anyone under this agreement may
be by certificate, affidavit, document or other information which the person
acting on it considers pertinent and reliable, and signed, made or presented by
the proper party or parties.

          V-6.  THIRD PARTIES.  Except as otherwise provided by law, the
trustee"s exercise or non-exercise of its powers and discretions in good faith
shall be conclusive on all persons.  No one shall be obliged to see to the
application of any money paid 


                                     -15-
<PAGE>


or property delivered to the trustee, except to the extent such person is 
acting as an investment manager as respects such money or property.  The 
certificate of the trustee that it is acting according to this agreement will 
fully protect all persons dealing with the trustee.  An insurance company or 
investment manager may assume that this agreement and the plan have not been 
amended or changed unless notice of such amendment or change is received by 
the investment manager or by the insurance company at its home office.

          V-7.  NO REVERSION IN EMPLOYER.  The employers shall have no right,
title or interest in the trust fund, nor shall any part of the trust fund revert
or be repaid to an employer, directly or indirectly, unless:

          (a)  a contribution is made by such employer by mistake of fact
               and such contribution is returned to the employer within one
               year after payment to the trustee; or

          (b)  a contribution conditioned on the deductibility thereof is
               disallowed as an expense for federal income tax purposes and
               such contribution (to the extent disallowed) is returned to
               the employer within one year after the disallowance of the
               deduction; or

          (c)  the Internal Revenue Service initially determines that the
               plan, as applied to the employer, does not meet the
               requirements of Section 401(a) of the Internal Revenue Code,
               in which event, any trust assets attributable to
               contributions made by such employer shall be returned to it
               within one year of the date of the denial of qualification
               of the plan.

The amount of any contribution that may be returned to the employer pursuant to
subparagraph (a) or (b) above must be reduced by any portion thereof previously
distributed from the trust fund and by any losses of the trust fund allocable
thereto, and in no event may the return of such contribution cause any
participant"s account balances to be less than the amount of such balances had
the contribution not been made under the plan.

          V-8.  INTERESTS NOT TRANSFERABLE.  The interests of persons entitled

transferred, alienated, assigned or encumbered.  Notwithstanding the 
foregoing, to the extent that a participant has loans outstanding from the 
plan at the time distribution of his accounts is to commence, the amount of 
principal and interest then outstanding shall reduce the distribution of the 
account balances as set forth in the plan.

          V-9.  INDEMNIFICATION.  To the extent permitted by law, no present or
former plan administrator member, nor any person who is or was a director,
officer, or employee of the employer shall be personally liable for any act done
or omitted to be done in good faith in the administration of the plan or this
trust.  Any employee of an employer to whom the plan administrator or an
employer has delegated any portion of its responsibilities under the plan, any
person who is or was a director or officer of an employer, members and former
members of the plan administrator, and each of them, shall, to the extent
permitted by law, be indemnified and saved harmless by the employers (to the
extent not indemnified or saved harmless under any liability insurance or other
indemnification arrangement with respect to the plan or this trust) from and
against any and all liability or claim of liability to which they may be
subjected by reason of any act done or omitted to be done in good faith in
connection with the administration of the plan or this trust or the investment
of the trust fund, including all expenses reasonably incurred in their defense
if the employers fail to provide such defense after having been requested to do
so in writing.  The trustee shall be indemnified and saved harmless by the
employers with respect to any liability or claim of liability to which the
trustee shall be subjected by reason of its compliance with any directions given
in accordance with the provisions of the plan or this trust by an investment
manager, the plan administrator or employers, or any person duly authorized by
the plan administrator or the employers, or by reason of its failure to take any
action with respect to any assets of the trust fund that are subject to
investment direction from an investment manager or the plan administrator in the
absence of direction from the investment manager or the plan administrator,
including all expenses reasonably incurred in its defense if the employers fail
to provide such defense after having been requested to do so in writing.

          V-10.  LITIGATION BY PARTICIPANTS.  If a legal action begun against
the trustee, an employer or the plan administrator by or on behalf of any person
results adversely to that person, or if a legal action arises because of
conflicting claims to a participant"s or other person"s benefits, the cost to
the trustee, the employers or the plan administrator of defending the action
will be charged to the extent permitted by law to the sums, if any, which were
involved in the action or were payable to the person concerned.

          V-11.  LIABILITIES MUTUALLY EXCLUSIVE.  To the extent permitted by
law, the trustee, an investment manager, the employers and each plan
administrator member shall be responsible only for its own acts or omissions and
neither the plan administrator nor the trustee shall be required to collect any
contribution from an employer or any other person or to verify that it is in the
proper amount.  No insurance company shall be a party to this agreement for any
purpose or be responsible for the validity of this agreement, it being intended

be waived by the person entitled to such notice.

          V-15.  SUCCESSORS.  This agreement shall be binding on all persons
entitled to benefits under the plan and their respective heirs and legal
representatives, on the employers and its successors and assigns, on the trustee
and its successors and on the plan administrator members and their successors.
The term "employer" as used in the plan and this agreement includes any entity
that continues the plan and this trust in effect, as provided in the plan.


          V-16.  SEVERABILITY.  If any provision of this agreement is held to be
illegal or invalid, such illegality or invalidity shall not affect the remaining
provisions of this agreement, and it shall be construed and enforced as if such
illegal or invalid provision had never been inserted therein.

Section of the Internal Revenue Code of 1986 or the Employee Retirement Income
Security Act of 1974 shall include any comparable section or sections of any

     THIS EMPLOYMENT AGREEMENT (the "Agreement") is hereby made and entered into
as of this 12th day of November, 1998, by and between McWhorter Technologies,
Inc., a Delaware corporation (the "Company"), and John R. Stevenson (the
"Employee").
                                          
                                W I T N E S S E T H

     WHEREAS, the Employee is currently employed by the Company as its Chief
Executive Officer; 

     WHEREAS, the Employee desires to resign from his duties and position as
Chief Executive Officer effective March 1, 1999 (the "Effective Date"); 

     WHEREAS, the Employee possesses an intimate knowledge of the business and
affairs of the Company and its policies, procedures, methods and personnel; and

     WHEREAS, the Company desires to secure the services and employment of the
Employee on behalf of the Company in such other capacities as the parties may
determine, and the Employee is willing to render such services on the terms and
conditions set forth herein.

     NOW, THEREFORE, in consideration of the mutual covenants contained herein,
and intending to be legally bound hereby, the parties hereto agree as follows:

     1.  EMPLOYMENT TERM.  Subject to the terms and conditions of this
Agreement, following his resignation as the Company's Chief Executive Officer,
Employee hereby agrees to remain in the employment of the Company, and the
Company hereby agrees to continue to employ Employee, for the period commencing
on the Effective Date and 

<PAGE>

ending on February 29, 2004 (the "Employment Term").  The term of this Agreement
shall be coincident with the Employment Term.

     2.  DUTIES.

     (a)  During the Employment Term, the Employee shall serve as an employee of
the Company in such capacities, offices or positions as may be mutually agreed
upon between the Company and the Employee.  In such capacities, Employee agrees
to perform such duties, services and responsibilities incident to and consistent
with such position(s) as reasonably determined from time to time by the Board of
Directors of the Company (the "Board") and the Company's Chief Executive
Officer, including but not limited to, continuing involvement in such areas as
strategic planning, corporate development, and the colorant business.  

     (b)  The Employee will devote the level of time to his employment that is
specified for the applicable time periods in Schedule A hereto.  The Employee
will not, without the prior written approval of the Board, engage in any other
business activity that would reduce the number of such expected hours.

Effective Date and ending on February 28, 2004, he will not accept full time
employment with another employer and will remain available to return to full

additional offices or positions as the Employee and the Company may mutually
agree upon.  Notwithstanding anything to the contrary in this Agreement whether
express or implied, Employee shall not be obligated to return to full time
employment with the Company after the Effective Date unless Employee and the
Company mutually agree on all of the relevant terms and conditions relating to
such full time employment, including compensation and other benefits.  In the
event the parties fail to reach a mutually acceptable agreement regarding any
such requested return to full time 


                                         -2-

Term as follows:

<TABLE>
<CAPTION>

</TABLE>

During each of the remaining periods of the Employment Term, Employee's Salary

Payments under this Section 3(a) shall be made in regular installments in
accordance with the Company's general payroll practices; provided that payments
under the preceding sentence shall be made at the same time or times as the
Company pays such compensation to its non-employee directors.

     (b)  On the date hereof, the Company will grant to Employee an award of 
_____ restricted shares of Common Stock of the Company, pursuant to the
Company's 1996 Incentive Stock Plan (the "Plan").  The terms and conditions of
such restricted stock award shall be more fully set forth in a formal stock
award entered into between the Company and Employee substantially in the form
attached as Exhibit A hereto.  Following the Company's fiscal year ending
October 31, 1999, Employee shall be considered an eligible participant in the
Plan and shall be entitled to receive an additional award of restricted shares
of Common Stock for that number of shares, if any, as may be determined by the
Board in its sole discretion.

     (c)  Employee shall be solely responsible for taxes imposed on him by
reason of any compensation or benefits provided hereunder and the Company shall
be entitled to 


                                         -4-

<PAGE>

withhold from all such compensation and benefits all applicable taxes required

during the Employment Term:

     (a)  The Company shall furnish Employee with, and Employee shall be allowed
full use of, office facilities, automobiles, secretarial and clerical

the Employment term, and to non-employee directors, during the balance of the
Employment Term,  of the Company from time to time;

     (b)  Except as otherwise provided in Section 4(d) hereof, Employee shall be
eligible to participate in any non-discretionary compensation or employee
benefit plans or programs, if any, maintained by the Company from time to time
for its executive employees, including, but not limited to, life, health,
dental, and long-term disability insurance programs, employee stock ownership
plans, 401(k) and other pension programs, and other fringe benefit programs, in
all events subject to the terms of such plans or programs adopted by the
Company;

     (c)  Employee shall also be eligible to participate in, and to receive
benefits under, any discretionary compensation plans or programs, if any,
maintained by the Company from time to time for its executive employees,
including, but not limited to, stock purchase programs, stock option plans,
bonus plans, or other incentive or deferred compensation plans or programs,
provided that Employee's participation, if any, under any such discretionary
plans or programs shall at all times be determined by the Board in its sole
discretion;

     (d)  If at any time during the Employment Term Employee is not otherwise
eligible to participate in the Company's group medical or dental plans because
he does not work 


                                         -5-

<PAGE>

the minimum number of hours specified in the plan for eligibility, and during
periods after the Employment Term (but not beyond the earlier of (i) the deaths
of both he and his spouse or (ii) he and his spouse both attaining age 65),
Employee and his spouse shall be eligible to participate in such plans on the
same basis and at the same cost as former married employees of the Company who
have elected COBRA continuation coverage under Part 6 of Title I of ERISA
(without regard to the time limit in Section 602(2)(A)(i) of ERISA).

     (e)  The Company shall reimburse Employee for all reasonable out-of-pocket
expenses incurred by Employee in the performance of his duties hereunder in
accordance with the Company's policies from time to time in effect, provided
that Employee presents an itemized statement of such expenditures, which
itemized statement shall comply with the Company's expense reimbursement
procedures.

     5.  TERMINATION.  Notwithstanding anything to the contrary in this
Agreement whether express or implied, Employee's employment with the Company and
the Employment Term shall terminate upon the expiration of the Employment Term
or upon the earlier occurrence of any of the following events:

     (a)  The death of the Employee.

     (b)  The voluntary termination of employment by Employee.  Employee shall
have the right to terminate this Agreement and the Employment Term at any time
and for any reason  upon delivery of prior written notice to the Company not
less than sixty (60) days prior to the effective date of such termination.
Notwithstanding anything to the contrary herein, whether express or implied, in
the event that Employee voluntarily terminates his employment with the Company
at any time following a "Change of Control" of the Company (as defined in the
Grant of Nonqualified Stock Option to Employee from the Company dated November
13, 1997), Employee's employment shall be deemed for all purposes of this
Agreement to have been terminated by the Company without Cause, 


                                         -6-

<PAGE>

thereby entitling the Executive to the post-termination benefits provided for
under Section 5(f) hereof.

     (c)  The termination of employment by the Company for Cause.  Termination
of employment for "Cause" shall mean termination based on the Employee's breach
of this Agreement, conduct by the Employee that is dishonest, fraudulent or
unlawful, gross negligence, or willful misconduct by the Employee, in any case,
which discredits or materially damages the Company.

     (d)  The termination of employment by the Company for Disability.  In the
event that during the Employment Term Employee shall be unable to perform his
duties under this Agreement for 180 consecutive days during any twelve-month
period due to illness, accident or other incapacity (as determined in good faith
by the Board) or if a physician selected in good faith by the Board (and
consented to by Employee or his personal representative) examines Employee and
advises the Company that it is likely that Employee will be unable to perform
such duties for 180 consecutive days during the succeeding twelve-month period
(a "Disability"), the Company may elect to terminate Employee's employment by
sending written notice of such election to Employee at any time during the
period of such disability.

     (e)  After any termination of Employee's employment hereunder for any
reason, Employee (or his legal representative) shall be entitled to 
receive accrued and unpaid Salary and expense reimbursements due for the period
ending on the effective date of such termination.  After termination of
Employee's employment hereunder for any reason, the Company and the Employee
shall have no further obligations hereunder except as otherwise described in
this Section 5(e) and in Sections 4(d), 5(f), 5(g), 6, and 9 hereof. 

     (f)  If the Employee's employment with the Company terminates after the
date hereof for any reason OTHER THAN (i) a termination by the Company for Cause
pursuant to Section 5(c) hereof, or (ii) a voluntary termination by Employee
pursuant to Section 5(b) 


                                         -7-

<PAGE>

(except as otherwise expressly provided in the last sentence of Section 5(b)
hereof), in addition to the amounts described in the preceding paragraph, the
Company will be obligated to continue to pay Employee an amount equal to
Employee's Salary at the rates set forth in Section 3 hereof, for the period
beginning on the effective date of such termination and ending on February 29,
2004. 

     (g)  In the event of termination of this Agreement for any reason other
than Employee's death or Disability, Employee agrees to cooperate with the
Company and to be reasonably available to the Company with respect to continuing
and/or future matters arising out of the Employee's employment or any other
relationship with the Company, whether such matters are business-related, legal
or otherwise.  The provisions of this paragraph shall survive termination of
this Agreement.

     6.  EXPENSES.  The Company will pay or reimburse Employee for all costs and
expenses (including court costs and reasonable attorneys' fees) incurred by
Employee as a result of any claim, action or proceeding arising out of, or
challenging the validity or enforceability of, this Agreement or any provision
hereof.

     7.  MITIGATION.  In the event of a termination of Employee's employment for
any reason, Employee shall not be required to seek other employment; in
addition, no amount payable under Section 6 of this Agreement, if any, following
the termination of Employee's employment with the Company, shall be reduced by
any compensation earned by Employee as a result of employment by another
employer after such termination of employment with the Company.

     8.  DESIGNATED BENEFICIARY.  In the event of the death of Employee while in
the employ of the Company, or at any time thereafter during which amounts remain
payable to Employee under Section 5 hereof, such payments shall thereafter be
made to such person or persons as Employee may specifically designate
(successively or contingently) to receive payments under this Agreement
following Employee's death by filing a written 


                                         -8-

<PAGE>

beneficiary designation with the Company during Employee's lifetime.  Such
beneficiary designation shall be in such form as may be prescribed by the
Company and may be amended from time to time or may be revoked by Employee
pursuant to written instruments filed with the Company during his lifetime. 
Beneficiaries designated by Employee may be any natural or legal person or
persons, including a fiduciary, such as a trustee of a trust or the legal
representative of an estate.  Unless otherwise provided by the beneficiary
designation filed by Employee, if all of the persons so designated die before
Employee or on the occurrence of a contingency not contemplated in such
beneficiary designation, or if Employee shall have failed to provide such
beneficiary designation, then the amount payable under this Agreement shall be
paid to Employee's estate.

     9.  EMPLOYEE COVENANTS.

     (a)  During the Employment Term and for a period of two years thereafter,
the Employee shall not (i) disclose any information likely to be regarded as
confidential and relating to the Company's business, (ii) solicit the Company's
employees to work for a competitor of the Company, or (iii)  perform any act
detrimental to the Company or its employees, including, but not limited to,
disparaging the Company, its senior management or its products.

     (b)  The Employee agrees that any breach or threatened breach of Section
9(a) shall entitle the Company to apply for and to obtain injunctive relief,

the Company at law or in equity.

     (c)  All of the Employee rights and benefits under this Agreement shall
cease upon any material breach by the Employee of Section 9(a) of this
Agreement.

     10.  NON-WAIVER OF RIGHTS.  The failure to enforce at any time the
provisions of this Agreement or to require at any time performance by the other
party of any of the provisions hereof shall in no way be construed to be a
waiver of such provisions or to 


                                         -9-

<PAGE>

affect either the validity of this Agreement or any part hereof, or the right of

                        STOCK AWARD AND RESTRICTION AGREEMENT


     Pursuant to your employment agreement dated November __, 1998 (the
"Employment Agreement") with McWhorter Technologies, Inc. (the "Company"), the
Company has agreed to grant you an award of restricted stock under the Company's
1996 Incentive Stock Plan (the "Plan"), as specified below:

     GRANTEE: John R. Stevenson
     DATE OF GRANT:  November __, 1998
     NUMBER OF SHARES OF RESTRICTED STOCK GRANTED: _________

THIS DOCUMENT CONSTITUTES PART OF THE PROSPECTUS COVERING SECURITIES THAT HAVE
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933.

     THIS AGREEMENT, effective as of the Date of Grant set forth above, is
between McWhorter Technologies, Inc., a Delaware corporation (the "Company") and
the Grantee named above (the "Grantee"), covering a grant by the Company to the
Grantee of shares of Restricted Stock under the Plan.

     1.   GRANT OF SHARES.  Pursuant to action of the Board of Directors of 
the Company and the Compensation Committee of the Board of Directors of the 
Company (the "Committee"), and in consideration of valuable service 
heretofore rendered by the Grantee to the Company and of the agreements 
contained in the Employment Agreement, the Company hereby grants to the 
Grantee  a Stock Award of shares of common stock, $.01 par value, of the 
Company (the "Shares"), subject to the Restrictions set forth in Section 2 
and the other terms and conditions of the Plan and this Agreement.  The 
Shares shall be recorded in the books of the Company and the Company's 
transfer agent in the Grantee's name.  The Grantee shall have all the rights 
of a stockholder with respect to the Shares, including the right to vote and 
to receive all dividends or other distributions paid or made with respect to 
the Shares.  However, any securities of the Company which may be issued

<PAGE>


with respect to such Shares by virtue of any stock split, combination, stock 
dividend or recapitalization shall be deemed to be "Shares" hereunder and 
shall be subject to all the terms and conditions of the Plan and this 
Agreement.

     2.   RESTRICTIONS.  The Shares may not be sold, exchanged, assigned,
transferred, pledged or otherwise disposed of, and shall be subject to
forfeiture as set forth in Section 4 below (the "Restrictions") unless and until
such Restrictions shall have lapsed as set forth in Section 3 below. 

     3.   TERMINATION OF RESTRICTIONS.  In the event that Grantee's employment
by the Company terminates for any reason other than (i) Cause (as defined in the
Employment Agreement) or (ii) the voluntary termination by Grantee prior to
February 28, 2001, any Restrictions which have not lapsed will lapse
immediately.  In the event of a "Change of Control" of the Company (as defined
in the Grant of Nonqualified Stock Option to Grantee from the Company dated
November 13, 1997) any Restrictions which have not lapsed will lapse
immediately.  Any Restrictions which have not lapsed by February 29, 2004 will
lapse on that date.

     4.   FORFEITURE OF SHARES.  In the event of the termination of the
Grantee's employment by the Company for Cause or a voluntarily termination by
Grantee prior to February 28, 2001 and prior to a "Change of Control" of the
Company, all of the Shares then subject to the Restrictions shall be forfeited
to the Company by the Grantee, without consideration to the Grantee or Grantee's
executor, administrator, personal representative or heirs ("Representative").

     5.   DELIVERY OF CERTIFICATES.  Certificates representing Shares as to
which the Restrictions have lapsed shall be issued in the name of the Grantee
and delivered by the Company to the Grantee or the Grantee's Representative.

     6.   WITHHOLDING TAXES.  The lapse of the Restrictions on any Shares
pursuant to Section 3 above shall be conditioned on the Grantee or the Grantee's
Representative having made appropriate arrangements with the Company to provide
for the payment of any taxes required to be withheld by Federal, State or local
law in respect of such lapse.

     7.   NOTICES.  All notices hereunder shall be in writing and shall be
deemed to be given when delivered in person or upon the second day after the
same are deposited in the U.S. Mail, postage prepaid by certified mail,

applicable to the notice provisions of Section 11 of the Employment Agreement. 
Either party may designate a different address for its receipt of notice by

Shares are forfeited pursuant to Section 4, or the date the Restrictions have
lapsed.

                                AMENDMENT NO. 1998-1
                                        TO 
                            McWHORTER TECHNOLOGIES, INC.
                             DEFERRED COMPENSATION PLAN
                                          
     McWhorter Technologies, Inc., a Delaware corporation (the "Company"), 
pursuant to the power granted to it by Section 11.2 of the McWhorter 
Technologies, Inc. Deferred Compensation Plan (the "Plan"), hereby amends the 
Plan as follows, effective as of  August 19, 1998:

1.   A new Section 1.9 shall be added, and all subsequent Sections in Article 1
     accordingly renumbered, as follows:

     1.9  ""Annual Installment Method" shall be an annual installment payment
     over the number of years selected by the Participant in accordance with
     this Plan calculated as follows:  The Stock Account Balance shall be
     calculated as of the close of business on the last business day of the
     year.  The annual installment shall be calculated by multiplying this
     balance by a fraction, the numerator of which is one, and the denominator
     of which is the remaining number of annual payments due the Participant. 
     By way of example, if the Participant elects a 10-year Annual Installment
     Method, the first payment shall be 1/10 of the Participant's Stock Account
     Balance, calculated as described in this definition.  The following year,
     the payment shall be 1/9 of the Participant's Stock Account Balance,
     calculated as described in this definition.  Each annual installment shall
     be paid on or as soon as practicable after the last business day of the
     applicable year."

2.   A new Section 1.18 shall be added, and all subsequent Sections in Article 1
     accordingly renumbered, as follows:

     1.18 ""Cash Account Balance" shall mean, as to a Participant, that portion
     of his or her Account Balance which is attributable to his or her Base
     Annual Salary Account, Annual Bonus Account and Company Contribution
     Account."

3.   A new Section 1.51 shall be added, and all subsequent Sections in Article 1
     accordingly renumbered, as follows:
     
     1.51 ""Stock Account Balance" shall mean, as to a Participant, that
     portion of his or her Account Balance which is attributable to his or her
     Stock Option Deferral Account, ESOP Restoration Subaccount and Restricted
     Stock Account."

McWHORTER TECHNOLOGIES, INC.
DEFERRED COMPENSATION PLAN
- -------------------------------------------------------------------------------

4.   Section 3.12 shall be restated in its entirety as follows:
     
     "INTEREST CREDITING FOR INSTALLMENT OBLIGATIONS.  
     (a)  "CASH ACCOUNT BALANCE.  A Participant's benefits under this Plan which
     are attributable to his or her Cash Account Balance shall be paid either in
     lump sum or in equal monthly installments in accordance with such
     Participant's Election Form.  If a Participant's benefits attributable to
     his or Cash Account Balance are paid in installments, such payments shall
     be determined by amortizing the Participant's specified benefit over the
     number of months elected, using the interest rate specified below and
     treating the first installment payment as all principal and each subsequent
     installment payment, first as interest accrued for the applicable
     installment period on the unpaid Cash Account Balance and second as a
     reduction in the Cash Account Balance.  The interest rate to be used to
     calculate installment payment amounts shall be a fixed interest rate that
     is determined by averaging 100% of the Moody's Rates for the Plan Year in
     which installment payments commence and the two (2) preceding Plan Years. 
     This rate shall be treated as the nominal rate for making such
     calculations.  If a Participant has completed fewer than three (3) Years of
     Plan Participation, this average shall be determined using 100% of the
     Moody's Rates for the Plan Years during which the Participant participated
     in the Plan.
     
     (b)  "STOCK ACCOUNT BALANCE. A Participant's benefits under this Plan which
     are attributable to his or her Stock Account Balance shall be paid either
     in lump sum or in installments in accordance with such Participant's
     Election Form.  If a Participant's benefits attributable to his or her
     Stock Account Balance are paid in installments, such payments shall be
     determined using the Annual Installment Method.  Any payment relating to a
     Participant's Stock Option Deferral Account, ESOP Restoration Subaccount or
     Restricted Stock Account shall be payable only in Stock."

5.   A new sentence shall be added to the end of Section 4.3 as follows:
     
     "Notwithstanding the foregoing, any Withdrawal Amount relating to a
     Participant's Stock Option Deferral Account, ESOP Restoration Subaccount or
     Restricted Stock Account shall be payable only in Stock."

6.   Section 5.2 shall be restated in its entirety as follows:

     5.2  "PAYMENT OF RETIREMENT BENEFIT.  A Participant, in connection with his
     or her commencement of participation in the Plan, shall elect on an
     Election Form to receive his or her Retirement in a lump sum or in
     Iinstallments pursuant to Section 3.12.  The Participant may annually
     change his or her election as his or her Retirement Benefit to an allowable

McWHORTER TECHNOLOGIES, INC.
DEFERRED COMPENSATION PLAN
- -------------------------------------------------------------------------------

     alternative payout period and/or installment periods by submitting a new
     Election Form to the Committee, provided that any such Election Form is
     submitted at least one year prior to the Participant's Retirement and is
     accepted by the Committee in its sole discretion.  The Election Form most
     recently accepted by the Committee shall govern the payout of the
     Retirement Benefit.  If a Participant does not make any election with
     respect to the payment of the Retirement Benefit, then the entire
     Retirement Benefit shall be payable in a lump sum.  The lump sum payment
     shall be made, or installment payments shall commence, no later than
     60 days after the last day of the Plan Year in which the Participant
     Retires.  Any payment made shall be subject to the Deduction Limitation. 
     Notwithstanding the foregoing, any payment relating to a Participant's
     Stock Option Deferral Account, ESOP Restoration Subaccount or Restricted
     Stock Account shall be payable only in Stock."

7.   The reference in Section 5.3 to "months" shall be replaced by "years".

8.   A new sentence be added to the end of Section 6.2 as follows:

     "Notwithstanding the foregoing, any payment relating to a Participant's
     Stock Option Deferral Account, ESOP Restoration Subaccount or Restricted
     Stock Account shall be payable only in Stock."
 
9.   A new sentence shall be added to the end of Section 7.2 as follows:

     "Notwithstanding the foregoing, any payment relating to a Participant's
     Stock Option Deferral Account, ESOP Restoration Subaccount or Restricted
     Stock Account shall be payable only in Stock." 

10.  Section 11.1 shall be restated in its entirety as follows:

     11.1  "TERMINATION.  Although each Employer anticipates that it will
     continue the Plan for an indefinite period of time, there is no guarantee
     that any Employer will continue the Plan or will not terminate the Plan at
     any time in the future.  Accordingly, each Employer reserves the right to
     discontinue its sponsorship of the Plan and/or to terminate the Plan at any
     time with respect to any or all of its participating Employees, by action
     of its board of directors.  Upon the termination of the Plan with respect
     to any Employer, the Plan Agreements of the affected Participants who are
     employed by that Employer shall terminate and their Account Balances,
     determined as if they had experienced a Termination of Employment on the
     date of Plan termination or, if Plan termination occurs after the date upon
     which a Participant was eligible to Retire, then with respect to that
     Participant as if he or she had Retired on the date of Plan termination,
     shall be paid to the Participants as follows:  Prior to a Change in
     Control, if the Plan is


<PAGE>

McWHORTER TECHNOLOGIES, INC.
DEFERRED COMPENSATION PLAN
- -------------------------------------------------------------------------------

     terminated with respect to all of its Participants, an Employer shall 
     have the right, in its sole discretion, and notwithstanding any 
     elections made by the Participant, to pay such benefits pursuant to an 
     amortization period of 15 years (in the case of a Participant's Cash 
     Account Balance) or pursuant to an Annual Installment Method of 15 years 
     (in the case of a Participant's Stock Account Balance), with amounts 
     credited and debited during the installment period as provided herein.  
     If the Plan is terminated with respect to less than all of its 
     Participants, an Employer shall be required to pay such benefits in a 
     lump sum.  After a Change in Control, the Employer shall be required to 
     pay such benefits in a lump sum.  The termination of the Plan shall not 
     adversely affect any Participant or Beneficiary who has become entitled 
     to the payment of any benefits under the Plan as of the date of 
     termination; provided however, that the Employer shall have the right to 
     accelerate installment payments without a premium or prepayment penalty 
     by paying the Account Balance pursuant to an amortization period of 
     fewer years (in the case of a Participant's Cash Account Balance) or 
     pursuant to an Annual Installment Method using fewer years (in the case 
     of a Participant's Stock Account Balance); provided that the present 
     value of all payments that will have been received by a Participant at 
     any given point of time under the different payment schedule shall equal 
     or exceed the present value of all payments that would have been 
     received at that point in time under the original payment schedule."

11.  Section 11.2 shall be restated in its entirety as follows:

     11.2  "AMENDMENT. Any Employer may, at any time, amend or modify the Plan
     in whole or in part with respect to that Employer by the action of its
     board of directors; provided, however, that: (i) no amendment or
     modification shall be effective to decrease or restrict the value of a
     Participant's Account Balance in existence at the time the amendment or
     modification is made, calculated as if the Participant had experienced a
     Termination of Employment as of the effective date of the amendment or
     modification or, if the amendment or modification occurs after the date
     upon which the Participant was eligible to Retire, the Participant had
     Retired as of the effective date of the amendment or modification, and (ii)
     no amendment or modification of this Section 11.2 or Section 12.2 of the
     Plan shall be effective.  The amendment or modification of the Plan shall
     not affect any Participant or Beneficiary who has become entitled to the
     payment of benefits under the Plan as of the date of the amendment or
     modification; provided, however, that the Employer shall have the right to
     accelerate installment payments by paying the Account Balance in a lump
     sum, pursuant to an amortization period of fewer years (in the case of a
     Participant's Cash Account Balance) or pursuant to an Annual Installment
     Method using fewer years (in the case of a Participant's Stock Account
     Balance).  In all cases, the present value of all payments that will have
     been received by a Participant at any given point of time under the
     different payment schedule shall equal or exceed the present value of all
     payments that


<PAGE>

     would have been received at that point in time under the original 
     payment schedule.  Notwithstanding the foregoing, any payment relating 
     to a Participant's Stock Option Deferral, ESOP Restoration Subaccount or 
     Restricted Stock Account shall be payable only in Stock."

The Company has caused this Amendment to be signed by its duly authorized 
officer as of the date written below.
