ITEM 1.   BUSINESS
 
THE COMPANY
 
     Park-Ohio Industries, Inc. ("the Company"), an Ohio Corporation since
January, 1985, operates through two segments, Manufactured Products and
Logistics, which serve a wide variety of industrial markets. Manufactured
Products designs and manufactures a broad range of high quality products
engineered for specific customer applications. The principal customers of
Manufactured Products are original equipment manufacturers ("OEMs") and
end-users in the automotive, railroad, truck and aerospace industries. Logistics
is a leading national supplier of fasteners (e.g., nuts, bolts and screws) and
other industrial products to OEMs, other manufacturers and distributors. In
connection with the supply of such industrial products, Logistics provides a
variety of value-added, cost-effective procurement solutions. The principal
customers of Logistics are in the transportation, industrial, electrical and
lawn and garden equipment industries. The Company's diversified operations
moderate the effect on the Company of downturns affecting individual operating
units and industries served. Between 1993 and 1997, the Company has grown
significantly, both internally and through acquisitions. Over this period, the
Company's net sales increased from $94.5 million to $441.1 million, income from
continuing operations increased from $3.7 million to $11.3 million, and EBITDA
increased from $7.2 million to $40.0 million.
 
RECENT DEVELOPMENTS
 
     The Company completed five acquisitions for cash in 1997 (collectively, the
"1997 Acquisitions"). In January 1997, the Company acquired the assets of Green
Ball Bearing Company ("Green Bearing"), a manufacturer of wheel, hub and clutch
bearings for the automotive aftermarket, for $0.7 million. In February 1997, the
Company acquired the assets of Feco Engineered Systems Limited ("Feco"), which
produces complete oven systems that combine heat processing and curing
technologies with material handling and conveying methods, for approximately $3
million. In May 1997, the Company acquired the assets of The Delo Screw Products
Company ("Delo"), a manufacturer of screw machine products, for $9.2 million.
These three Manufactured Products acquisitions were supplemented by two
acquisitions of Logistics businesses. In July 1997, the Company acquired Arden
Industrial Products, Inc. ("Arden") for approximately $44 million. In October
1997, the Company acquired the assets of Arcon Fastener Corporation ("Arcon")
for $5.6 million.
 
     The information contained under the headings of "Note B -- Acquisitions"
and "Note C -- Sale of Bennett Industries" of notes to consolidated financial
statements included herein, relating to recent acquisitions and dispositions is
incorporated herein by reference.
 
OPERATIONS
 
     The Company conducts its business through two segments: Manufactured
Products and Logistics. Manufactured Products consists of five groups, certain
of which are comprised of multiple businesses. Each of the Company's operating
units has its own management team and maintains its own independent market
identity. The following chart highlights the Company's two business segments,
the key products they sell and the primary industries they serve:

MANUFACTURED PRODUCTS
 
     Manufactured Products operates through five groups which capitalize on the
Company's expertise in efficiently converting raw materials into high quality
finished products. The five groups include: Aluminum Casting, Forged and
Machined Products, Capital Equipment, Metal Forming and Industrial Rubber
Products. Manufactured Products generated net sales of $222.4 million, or 51% of
the Company's net sales for the year ended December 31, 1997. The three largest
customers, comprised of many divisions, accounted for approximately 31% of
manufactured products sales in 1997. The loss of business from any one of these
customers would have an adverse effect on this segment.

ALUMINUM CASTING GROUP
 
     The Aluminum Casting Group operates through General Aluminum Mfg. Company
("GAMCO") and its wholly owned subsidiary. The Aluminum Casting Group, which
manufactures aluminum permanent mold castings primarily for the automotive
industry, generated net sales of $36.5 million for the year ended December 31,
1997, which represented 8% of the Company's net sales for such period.
 
     Products and Services.   GAMCO manufactures aluminum permanent mold
castings used primarily in automobile transmissions and engines. GAMCO's
aluminum castings are manufactured by transferring molten aluminum from a
melting furnace to a steel mold in which the aluminum then solidifies into the
final product. GAMCO's principal automotive products include: transmission pump
housings, planetary pinion carriers, clutch retainers, rotor castings and
bearing cups. In addition, GAMCO manufactures products for non-automotive end
users such as surgical table components, light housings and electrical meter
housings. GAMCO also provides value-added services such as secondary casting,
machining, drilling, tapping and part assembly.
 
     GAMCO's cast aluminum parts are critical components manufactured primarily
for automotive OEMs. Although these parts are lightweight, they possess high
durability and integrity characteristics even under extreme pressure and
temperature conditions. Demand by automotive OEMs for aluminum permanent mold
products has increased in recent years as OEMs have sought lighter alternatives
to heavier steel and iron components. Lighter aluminum cast components increase
an automobile's fuel efficiency without decreasing its structural integrity.
Management believes this replacement trend will continue as government standards
regarding fuel efficiency become increasingly stringent.
 
     Markets and Customers.   GAMCO sells its products primarily to customers
located in North America. The market for aluminum permanent mold castings is
comprised of two segments: automotive and non-automotive.
 
     Competition.   The domestic aluminum permanent mold industry is highly
competitive and consists of several large participants. The Company's principal
competition comes from several large domestic companies, each of which provides
a broad array of products manufactured from a variety of metals, including
aluminum. GAMCO competes principally on the basis of its ability to: (i)
engineer and manufacture high quality, semi-machined castings in large volumes;
(ii) provide timely delivery; and (iii) retain the manufacturing flexibility
necessary to quickly adjust to the needs of its customers. Although there are a
number of smaller domestic companies with aluminum permanent mold casting
capabilities, the automotive industry's stringent quality and service standards
enable only large suppliers with the requisite quality certifications to compete
effectively. As one of these suppliers, GAMCO has benefited in recent years as
automotive OEMs have consolidated their supplier base. GAMCO, a well-established
name in the aluminum permanent mold industry, has achieved QS-9000 and ISO 9002
certifications and has been awarded numerous supplier quality awards.
 
FORGED AND MACHINED PRODUCTS GROUP
 
     The Forged and Machined Products Group consists of four operating units:
Park Drop Forge, Ohio Crankshaft, Cleveland City Forge and Blue Falcon Forge.
The Forged and Machined Products Group designs and manufactures crankshafts,
camshafts and other high strength, high performance structural parts primarily
for aircraft and locomotive manufacturers. The Forged and Machined Products
Group generated net sales of $49.9 million for the year ended December 31, 1997,
which represented 11% of the Company's net sales for such period.
 
     Products and Services.   The Forged and Machined Products Group produces,
machines and finishes closed-die metal forgings for customers in the railroad,
aerospace, power generation, shipbuilding, construction and off-road vehicle
industries. The forging process enables metal to be shaped while generally
retaining higher structural integrity than metal shaped through other processes.
Ohio Crankshaft, one of the largest independent designers and machiners of
crankshafts and camshafts in the United States, machines, induction hardens and
surface finishes crankshafts and camshafts used prima-

rily in locomotives, power generators and ships. Park Drop Forge manufactures

LOGISTICS
 
     Logistics is a leading national supplier of over 150,000 standard and
specialty fasteners and other industrial products pursuant to either supply
chain management agreements or traditional wholesale supply arrangements.
Logistics operates out of 33 branches located throughout the United States, two
branches in Mexico and branches in Canada, Puerto Rico and England, and has a
central distribution center located in Dayton, Ohio. Logistics generated net
sales of $218.7 million, or 49% of the Company's net sales for the year ended
December 31, 1997. The three largest customers, comprised of many divisions,
accounted for approximately 22% of sales of Logistics. The loss of any one of
these customers would have an adverse effect on this business.
 
     Products and Services.   Supply chain management, which is Logistics'
primary focus for future growth, involves offering customers procurement
solutions and comprehensive, on-site management for most of their fastener and
related hardware needs. Supply chain management customers receive value-added
services, such as part usage and cost analysis, product redesign
recommendations, supplier selection, quality assurance, bar coding, product
packaging and tracking, just-in-time delivery, electronic billing services and
ongoing technical support. Supply chain management services are typically
provided to customers' facilities pursuant to total fastening services ("TFS")
contracts. TFS contracts enable Logistics' customers to both reduce procurement
costs and better focus on their companies' core manufacturing competencies by:
(i) significantly reducing the administrative and labor costs associated with
fastener procurement by outsourcing certain internal purchasing, quality control
and inventory fulfillment responsibilities; (ii) reducing the amount of working
capital invested in inventory; (iii) achieving purchasing efficiencies as a
result of vendor consolidation; and (iv) receiving technical expertise in the
selection of fastener and other components for certain manufacturing processes.
Management believes that TFS contracts foster longer-lasting supply
relationships with customers, who increasingly rely on the Company for their
fastener needs, as compared to traditional buy/sell distribution relationships.
Sales pursuant to TFS contracts have increased significantly in recent years and
represented over 60% of Logistics' net sales for the year ended December 31,
1997. Logistics' remaining sales are generated through the wholesale supply of
fasteners and other industrial products to OEMs, other manufacturers and
distributors pursuant to master or authorized distributor relationships.
 
     Logistics supplies standard and specialty engineered fasteners such as
nuts, bolts, screws and washers. In addition to fasteners, Logistics supplies,
among other things, valves, fittings, clamps and rubber products, which
currently represent approximately 10% of Logistics' net sales. Logistics also
provides engineering and design services to its customers.
Applications-engineering specialists and the direct sales force work closely
with the engineering staff of OEM customers to recommend the appropriate
fasteners for a new product or to suggest alternative fasteners that reduce
overall production costs, streamline assembly or enhance the appearance or
performance of the end product.
 
     Markets and Customers.   In 1997, more than 95% of Logistics' net sales
were to domestic customers. The domestic industrial fastener market is estimated
by industry sources to have generated between $7 and $9 billion in annual sales
in 1997 at the wholesale level. Fasteners are used extensively by OEMs in a
variety of industries, and demand is generally related to the state of the
economy and to the overall level of manufacturing activity.
 
     Logistics markets and sells fasteners and other industrial products to over
7,000 customers domestically and internationally. The principal markets served
by Logistics are transportation equipment, including manufacturers of heavy
trucks, recreational vehicles and automotive parts and accessories,
 
                                        6
<PAGE>   9
 
industrial equipment, electrical equipment, including manufacturers of
electrical controls, appliances and motors, lawn and garden equipment and HVAC.
 
     In recent years, OEMs have made it a priority to reduce their total cost of
purchasing and handling fasteners. Due to the low unit cost and the large number
of different fasteners used to manufacture or assemble a single product,
administrative and overhead costs comprise a substantial portion of an OEM's
fastener-related costs. As a result, management believes that the number of
industrial fastener suppliers are consolidating as OEMs rely on fewer suppliers
to achieve purchasing efficiencies. Larger suppliers such as the Company that
provide a wide array of value-added services and are reliable sources for
just-in-time delivery are best positioned to capitalize on these trends. In
addition, OEMs are increasingly relying on fastener suppliers to provide design
and applications engineering support, enabling more efficient use of internal
engineering resources. Management believes that these developments will allow
Logistics to increase the amount of low unit cost fastener and non-fastener
items supplied to OEMs.
 
     Competition.   The industrial fastener supply industry is highly
competitive and fragmented, with over 2,500 domestic full-line, industrial
fastener suppliers and other domestic suppliers that offer a limited number of
fasteners in addition to other industrial products. Management believes that
substantially all of Logistics' competitors operate on a regional basis and do
not provide customers with the wide array of value-added services offered by
larger suppliers such as the Company. Logistics competes primarily on the basis
of its value-added services, extensive product selection and price with
primarily domestic competitors who are capable of providing inventory management
programs.
 
SALES AND MARKETING
 
     Each of the operating units within Manufactured Products markets and sells
its products through both internal sales personnel and independent sales
representatives. In some instances, the internal engineering staff assists in
the sales and marketing effort through joint design and applications-engineering
efforts with major customers. In addition, some Manufactured Products operating
units market certain of their products through various regional and national
trade shows.
 
     Logistics markets its products and services in the United States, Mexico,
Canada and Europe, primarily through its direct sales force, which is assisted
by applications engineers who provide the technical expertise necessary to
assist the engineering staff of OEM customers in designing new products and
improving existing products. Logistics often obtains new customers as a result
of referrals from existing customers.
 
RAW MATERIALS AND SUPPLIERS
 
     Manufactured Products purchases substantially all of its raw materials,
principally metals and certain component parts incorporated into its products,
and Logistics purchases substantially all of its fasteners, from third-party
suppliers and manufacturers. Management believes that raw materials and
component parts other than certain specialty fasteners are available from
alternative sources. Most raw materials required by Manufactured Products are
commodity products available from several domestic suppliers. Park Drop Forge
supplies approximately 75% of the closed-die steel forgings used in the
production of crankshafts and camshafts by Ohio Crankshaft. Logistics has
multiple sources of supply for standard products, but has limited supply sources
for certain specialty products. Approximately 10% of Logistics' fasteners are
purchased from suppliers in foreign countries, primarily Taiwan, Japan and
Korea. The Company is dependent upon the ability of such suppliers to meet
stringent quality and performance standards and to conform to delivery
schedules. In addition, operating units of Manufactured Products supply
approximately $5 million of products to Logistics.
 
EMPLOYEES
 
     As of December 31, 1997, the Company had a total of 2,659 employees, of
whom 2,637 were employed by the Company's operating units. Approximately 635
employees are subject to collective
                                        7
<PAGE>   10
 
bargaining agreements that expire between May 1998 and June 2001. The Company
believes that its collective bargaining agreements will be renegotiated and
extended in the ordinary course of business. In the last six years, the Company
has experienced labor strikes at two operating units of Manufactured Products.
The following table provides information relating to the employees of the
Company's operating units as of December 31, 1997:

</TABLE>
 
     Management believes that Manufactured Products' backlog as of any
particular date may not be indicative of sales for any future period. The
Company expects that all of Manufactured Products' backlog as of December 31,
1997 will be shipped by December 31, 1998. Management believes that backlog is
not a meaningful measure for the Company's Logistics operating units, as a
majority of Logistics' customers require just-in-time delivery of fasteners and
other industrial products.
 
RESEARCH AND DEVELOPMENT
 
     Research and development activities are conducted separately by each
operating unit. The Company's operating units focus on engineering products to
meet specific customer application requirements. Teams representing different
functional areas within an operating unit work closely with customers early in
the product design process to ensure that products meet customer specifications
and are designed for ease of manufacturing. As a general matter, the Company's
operating units have not required substantial research and development
expenditures.
 
ENVIRONMENTAL REGULATIONS
 
     The Company is subject to numerous federal, state and local laws and
regulations designed to protect public health and the environment
("Environmental Laws"), particularly with regard to discharges and emissions, as
well as handling, storage, treatment and disposal, of various substances and
wastes. Pursuant to certain Environmental Laws, owners or operators of
facilities may be liable for the costs of response or other corrective actions
for contamination identified at or emanating from current or former locations,
without regard to whether the owner or operator knew of, or was responsible for,
the presence of any such contamination, and for related damages to natural
resources. Additionally, persons who arrange for the disposal or treatment of
hazardous substances or materials may be liable
 
                                        8
<PAGE>   11
 
for costs of response at sites where they are located, whether or not the site
is owned or operated by such person.
 
     The Company believes that it is currently in material compliance with
applicable Environmental Laws. In general, the Company has not experienced
difficulty in complying with Environmental Laws in the past, and compliance with
Environmental Laws has not had a material adverse effect on the Company's
financial condition, liquidity and results of operations. The Company's capital
expenditures on environmental control facilities were not material during the
past five years and such expenditures are not expected to be material to the
Company in the foreseeable future.
 
     The Company has been identified as a potentially responsible party at
certain third-party sites under the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, as amended, or comparable state laws
which provide for strict and, under certain circumstances, joint and several
liability. The Company is participating in the cost of certain clean-up efforts
at several of these sites. However, the Company's share of such costs has not
been material and based on available information, the Company does not expect
its exposure at any of these locations to have a material adverse effect on its
results of operations, liquidity or financial condition.
 
     At its facility in Kent, Ohio, the Company is conducting remediation of
groundwater impacted by operations and disposal activities. Contaminants known
to be present in the groundwater at the facility and/or to have migrated
off-site include oil and certain volatile organic compounds. In addition, the
Company is conducting soil and groundwater investigations in connection with a
closure under the Resource Conservation and Recovery Act of 1976, as amended, of
hazardous waste storage areas associated with former metal plating operations.
To date, the majority of the approximately $2.5 million cost associated with all
of these efforts at the Kent facility has been shared equally between the
Company and the former owner of the facility under a cost-sharing agreement. The
availability of third-party payments or insurance for environmental remediation
activities is subject to risks associated with the willingness and ability of
the third party to make payments. The Company does not believe that future costs
to address the currently identified environmental issues at its facilities will
be material.

(a) Operating income is defined as net sales less cost of products sold,
    selling, general and administrative expenses and a restructuring charge. In
    1996, the Company incurred a restructuring charge of $2.7 million related to
    the consolidation of three of the Company's consumer products manufacturing
    facilities into one and the discontinuation of certain product lines.
 
(b) In 1996, other income was comprised of (i) a gain of $2.7 million in
    connection with the full settlement of subordinated notes receivable
    resulting from the sale of two manufacturing facilities and (ii) a gain of
    $1.5 million on the sale of certain securities by the Company in the third
    quarter of 1996.
 
(c) EBITDA is defined as earnings from continuing operations before interest,
    income taxes, depreciation, amortization, other income and non-recurring
    items. Non-recurring items include a restructuring charge of $2.7 million in
    the fourth quarter of 1996 related to the consolidation of three of the
    Company's consumer products manufacturing facilities into one and the
    discontinuation of certain product lines. EBITDA is not a measure of
    performance under generally accepted accounting principles ("GAAP"). While
    EBITDA should not be considered in isolation or as a substitute for net
    income, cash flows from operating activities and other income or cash flow
    statement data prepared in accordance with GAAP or as a measure of
    profitability or liquidity, management understands that EBITDA is
    customarily used as an indication of a company's ability to incur and
    service debt. See "Management's Discussion and Analysis of Financial
    Condition and Results of Operations" for a discussion of other measures of
    liquidity and operations that are covered by the audited financial
    statements. EBITDA as defined herein may not be comparable to other
    similarly titled measures of other companies.
 
(d) Earnings are defined as income from continuing operations before income
    taxes and fixed charges. Fixed charges are defined as interest expense and a
    portion of rental expense representing the interest factor, which the
    Company estimates to be one-third of rental expense, and amortization of
    deferred financing costs.
 
ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
     The consolidated financial statements of the Company include the accounts
of Park-Ohio Industries, Inc. and it subsidiaries after elimination of material
intercompany transactions and balances. The historical financial information of
the Company's continuing operations is not directly comparable on a year-to-year
basis due to the 1997 Acquisitions. During 1997, the Company acquired five
businesses, the largest of which was Arden Industrial Products, Inc. for $44.0
million as of August 1, 1997. Arden is a national distributor of specialty and
standard fasteners to the industrial market. In addition, during the year the
Company acquired four other businesses for an aggregate purchase price
approximating $18.5 million. All acquisitions were accounted for as purchases
and consequently their results are included in the consolidated financial
statements from their respective date of being acquired. In 1996, the Company
sold substantially all of the assets of Bennett Industries, Inc., a manufacturer
of plastic containers, in order to focus on its remaining manufacturing and
logistics businesses. Bennett generated net sales of $81.9 million in 1995. The
1996 and 1995 operating results of Bennett have been classified as discontinued
operations.

OVERVIEW
 
     The Company operates through two segments, Manufactured Products and
Logistics, that serve a wide variety of industrial markets. Manufactured
Products designs and manufactures a broad range of high quality products
engineered for specific customer applications. The principal customers of
Manufactured Products are OEMs and end-users in the automotive, railroad, truck
and aerospace industries. Logistics is a leading national supplier of fasteners
(e.g., nuts, bolts and screws) and other industrial products to OEMs, other
manufacturers and distributors. In connection with the supply of such industrial
products, Logistics provides a variety of value-added, cost-effective
procurement solutions. The principal customers of Logistics are in the
transportation, industrial, electrical and lawn and garden equipment industries.
Between 1994 and 1997, the Company has grown significantly, both internally and
through acquisitions. Over this period, the Company's net sales increased at a
51% compounded annual growth rate ("CAGR"), from $129.2 million to $441.1
million, and income from continuing operations increased at a 40% CAGR from $4.1
million on a fully taxed basis to $11.3 million.
 
     Growth since 1992 has been primarily attributable to the Company's strategy
of making selective acquisitions in order to complement internal growth.
Historically, the Company has acquired underperforming businesses with potential
for: (i) significant cost reductions through improved labor, supplier and
customer relations and increased purchasing power and (ii) revenue enhancement
due to better asset utilization and management practices, as well as increased
access to capital. The Company's internal growth has been driven primarily by
the addition of Logistics customers under TFS contracts and by the leveraging of
existing customer relationships at Manufactured Products.
 
     Between 1994 and December 31, 1997, the Company's continuing operations
incurred $45.2 million of capital expenditures, the majority of which was used
to expand and upgrade existing manufacturing facilities and enhance the
Company's management information systems.
 
RESULTS OF OPERATIONS
 
  1997 versus 1996
 
     Net sales from continuing operations increased by $93.4 million, or 27%,
from $347.7 million in 1996 to $441.1 million in 1997. Approximately 42% of this
increase was attributable to internal growth and 58% was a result of the 1997
Acquisitions. Of the internal sales growth, approximately 70% was primarily
attributable to the addition of TFS customers in the Logistics segment and the
remainder was due to increased orders from Manufactured Products' customers. Of
the growth in net sales attributable to the 1997 acquisitions, the majority
applies to the Logistics segment and primarily pertains to Arden which was
acquired as of August 1, 1997.
 
     Gross profit from continuing operations increased by $14.1 million, or 24%,
from $58.3 million in 1996 to $72.4 million in 1997. Of the increase, 79%
relates to the 1997 Acquisitions and 21% was due to internal growth. A majority
of the increase attributable to the 1997 Acquisitions was related to Arden. The
Company's consolidated gross margin from continuing operations decreased to
16.4% in 1997 from 16.8% in 1996. This decrease in consolidated gross margin was
primarily due to a change in the Company's revenue mix.
 
     Selling, general and administrative costs from continuing operations
increased by 16% to $44.4 million in 1997 from $38.1 million in 1996.
Approximately 93% of such increase was related to the 1997 Acquisitions.
Consolidated selling, general and administrative expenses decreased as a
percentage of net sales to 10.1% in 1997 from 11.0% in 1996 due to economies of
scale resulting from higher sales volume.
 
     Interest expense from continuing operations increased by $2.2 million from
$6.9 million in 1996 to $9.1 million in 1997 due to average debt outstanding in
1997 increasing by $19.9 million and to the reclassification in 1996 of
approximately $.8 million of interest expense to discontinued operations
resulting from the sale of Bennett Industries. Average interest rates for the
period were approximately the same in 1997 and 1996.
 
                                       14
<PAGE>   17
 
     As a result of the early extinguishment of the Company's 7 1/4% Convertible
Senior Subordinated Debentures due June 15, 2004, and its then existing bank
credit facility, the Company recorded an extraordinary charge of $1.5 million,
net of income taxes in 1997.
 
     At December 31, 1997, subsidiaries of the Company had net operating loss
carryforwards for tax purposes of approximately $9.4 million, subject to certain
limitations that expire between 2001 and 2007.
 
  1996 versus 1995
 
     On July 31, 1996, the Company completed the sale of substantially all of
the assets of Bennett for $50.8 million in cash, which resulted in a pre-tax
gain of $13.8 million. The results of operations and changes in cash flow of
Bennett have been classified as discontinued operations in the Company's
consolidated statements of income and cash flow for 1996 and 1995.
 
     Net sales from continuing operations increased by $58.2 million, or 20%,
from $289.5 million in 1995 to $347.7 million in 1996. Of this increase,
approximately $57.5 million was due to the inclusion of the results of
acquisitions made in 1995 in the Company's consolidated results for a full year
in 1996 as compared to a partial year in 1995.
 
     Gross profit from continuing operations increased by $9.7 million, or 20%,
from $48.6 million in 1995 to $58.3 million in 1996. Of this increase, $8.6
million was due to the inclusion of the results of acquisitions made in 1995 in
the Company's consolidated results for a full year in 1996 as compared to a
partial year in 1995. The remaining $1.1 million increase was primarily related
to Logistics' higher sales volumes and the addition of TFS customers. The
Company's consolidated gross margin was 16.8% in 1996 and 1995.
 
     Selling, general and administrative expenses from continuing operations
increased $8.1 million, or 27%, from $30.0 million in 1995 to $38.1 million in
1996. This increase was primarily a result of the inclusion of the acquisitions
made in 1995 in the Company's consolidated results for a full year in 1996 as
compared to a partial year in 1995 and higher overhead costs to support higher
sales levels. Consolidated selling, general and administrative expenses
increased as a percentage of net sales to 11.0% in 1996 from 10.4% in 1995
primarily as a result of the acquisitions consummated in 1995.
 
     During the fourth quarter of 1996, the Company commenced the reorganization
of its consumer products manufacturing operations which resulted in the
consolidation of three manufacturing facilities into one and the discontinuation
of certain product lines. As a result of these actions, the Company recorded a
non-cash charge of $2.7 million, primarily for the writedown of certain
property, equipment and inventory to their estimated realizable value.
 
     The Company had other income of $4.2 million in 1996 as compared to $.2
million in 1995. In 1996, other income was comprised of (i) a gain of $2.7
million from the lump sum payment as full settlement of subordinated notes
receivable, resulting from the Company's sale of two manufacturing facilities
and (ii) a gain of $1.5 million on the sale of securities. In 1995, other income
was comprised of a gain on the sale of securities.
 
     Interest expense from continuing operations increased $1.0 million from
$5.9 million in 1995 to $6.9 million in 1996, primarily due to higher levels of
bank debt outstanding during 1996 as compared to 1995. The Company's average
debt outstanding increased from $92.4 million in 1995 to $103.2 million in 1996.
The increase in average borrowings was caused by the acquisition of RB&W on
March 31, 1995 and higher levels of bank debt to support increased sales and
production as well as capital expenditures.
 
     During the fourth quarter of 1995, the Company determined that utilization
of its net operating loss carryforwards was assured and therefore recorded
deferred tax assets of $8.1 million. Consequently, as of January 1, 1996, the
Company's financial statements included a provision for Federal income taxes.
Federal income tax expense from continuing operations for 1995 was reduced by
$3.7 million due to the
 
                                       15
<PAGE>   18
 
utilization of net operating loss carryforwards. During 1996, as a result of the
gain on the sale of Bennett, all net operating loss carryforwards for tax
purposes relating to the Company were fully utilized. At December 31, 1996,
subsidiaries of the Company had net operating loss carryforwards for tax
purposes of approximately $15 million, subject to certain limitations that
expire between 2001 and 2007.
 
LIQUIDITY AND SOURCES OF CAPITAL
 
     The Company's liquidity needs are primarily for working capital and capital
expenditures. The Company's primary sources of liquidity have been funds
provided by operations and funds available from existing bank credit
arrangements. On January 14, 1998, the Company executed a "New Credit Agreement"
for $100 million on an unsecured basis from a group of banks which will be used
for general corporate purposes. The New Credit Agreement expires on April 30,
2001. Amounts borrowed under the New Credit Agreement may be borrowed at the
Company's election at either (i) the bank's prime lending rate less 1% or (ii)
LIBOR plus 90 basis points. As of December 31, 1997, $20.0 million was borrowed
under the facility.
 
     On November 25, 1997, the Company sold $150 million of its 9.25% Senior
Subordinated Notes due 2007. The Company used the net proceeds of the Senior
Notes along with borrowings under its new credit facility to (i) redeem its
7 1/4% Convertible Senior Subordinated Debentures due June 15, 2004 and (ii) to
repay substantially all amounts of its then existing credit facility.
 
     Capital expenditures for 1998 are anticipated to be approximately $16.0
million which will be used to invest in the Company's current facilities for
projected new business, for scheduled improvements and new equipment to expand
existing products.
 
     The ratio of current assets to current liabilities was 2.86 at December 31,
1997, compared to 2.78 at December 31, 1996 and 2.80 at December 31, 1995.
Working capital increased by $47.6 million to $147.3 million at December 31,
1997 from $99.7 million at December 31, 1996 as a result of the inclusion of the
1997 Acquisitions, primarily Arden, and to increases necessary to support the
internal growth of the Company.
 
     During 1997, the Company generated $27.2 million from continuing operations
before changes in operating assets and liabilities. After giving effect to the
use of $37.2 million in the operating accounts, the Company used $10.0 million
for operating activities. During the period, the Company invested $15.9 million
in capital expenditures and $60.4 million for acquisitions and investments
including the acquisition of Arden for $44.0 million. During the year, the
Company bought 221,494 shares of its common stock in the open market for $3.0
million. As of December 31, 1997, after issuing 199,000 common shares from the
treasury for the exercise of stock options, the Company has 148,719 shares of
its common stock in the treasury. During the year, 351,000 shares of common
stock were issued under stock option agreements for which the Company received
$3.2 million from the option holders. In addition, the Company purchased in the
open market $1.2 million of its convertible senior subordinated debentures.
These activities were funded by a net increase in long-term borrowings of $85.5
million and a decrease in cash balances of $2.8 million.
 
     During 1996, the Company generated $20.6 million from continuing operations
before changes in operating assets and liabilities. After giving effect to the
use of $14.9 million in the operating accounts and $2.0 million provided from
discontinued operations, the Company provided $7.7 million from operating
activities. During 1996, the Company invested $15.6 million in capital
expenditures and purchased 126,225 shares of its common stock for $1.8 million,
all of which were funded by internally generated cash flow and bank borrowings.
 
     During 1995, the Company generated $18.0 million from continuing operations
before changes in operating assets and liabilities. After giving effect to
changes in the operating accounts of $27.7 million and $5.7 million provided by
discontinued operations, the Company used $4.0 million in operating activities.
This amount and capital expenditures of $13.6 million were funded by an increase
in bank
 
                                       16

borrowings. In addition, the Company borrowed $68.6 million under its bank
facility to fund acquisitions, primarily RB&W, with an aggregate cash purchase
price of $35.8 million and to repay $32.8 million of acquired debt related to
the acquisitions.
 
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
     At December 31, 1997, the Company adopted Statement of Financial Accounting
Standards (SFAS) No. 128, "Earnings Per Share." All share and per share amounts,
including those of prior years, have been restated to comply with the new
provisions. In 1997, the Financial Accounting Standards Board issued SFAS No.
130, "Reporting Comprehensive Income," and SFAS No. 131, "Disclosures About
Segments of an Enterprise and Related Information," both of which expand or
modify disclosures and, accordingly, will have no impact on the Company's
financial position, results of operations or cash flows. These Statements are
effective for periods beginning after December 31, 1997, and will be adopted by
the Company in the first and fourth quarters of 1998, respectively.
 
IMPACT OF INFLATION
 
     Although inflation was not a significant factor in 1997, the Company
continues to seek ways to cope with its impact. To the extent permitted by
competition, the Company's operations generally attempt to pass on increased
costs by increasing sales prices over time. The Company primarily uses the FIFO
method of accounting for its inventories. Under this method, current costs are
generally reflected in cost of products. The charges to operations for
depreciation represent the allocation of historical costs incurred over past
years and are significantly less than if they were based on the current cost of
productive capacity being consumed.
 
YEAR 2000 CONVERSION
 
     The Company recognizes the need to ensure its operations will not be
adversely impacted by Year 2000 software failures. The Company has evaluated the
risks and is in the process of implementing actions to ensure the Company is
Year 2000 compliant. The cost of achieving Year 2000 compliance is not expected
to have a material adverse effect on the Company's results of operations or
financial condition.
 
ENVIRONMENTAL
 
     The Company has been identified as a potentially responsible party at
certain third-party sites under the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, as amended, or comparable state laws
which provide for strict and, under certain circumstances, joint and several
liability. The Company is participating in the cost of certain clean-up efforts
at several of these sites. However, the Company's share of such costs has not
been material and based on available information, the Company does not expect
its exposure at any of these locations to have a material adverse effect on its
results of operations, liquidity or financial condition.
 
SEASONALITY; VARIABILITY OF OPERATING RESULTS
 
     As a result of the significant growth in the Company's net sales and income
from continuing operations in recent years, seasonal fluctuations have been
substantially mitigated. The timing of orders placed by the Company's customers
has varied with, among other factors, orders for customers' finished goods,
customer production schedules, competitive conditions and general economic
conditions. The variability of the level and timing of orders has, from time to
time, resulted in significant periodic and quarterly fluctuations in the
operations of the Company's business units. Such variability is particularly
evident at the businesses in the Capital Equipment Group, which typically ship a
few large systems per year. In addition, the Company experiences seasonality in
the Kay Home Products operating unit of the Metal Forming Group. Kay Home
Products' goods are typically used by consumers in the spring and summer and
consequently its first two quarters of operating results are typically the
strongest.

FORWARD-LOOKING STATEMENTS
 
     This Annual Report to Shareholders and Form 10-K contains and incorporates
by reference certain statements that are "forward-looking statements" within the
meaning of Section 27A of the Securities Act and Section 21E of the Exchange
Act. Certain statements in this Management's Discussion and Analysis of
Financial Condition and Results of Operations contain forward-looking
statements, including without limitation, discussion regarding the Company's
anticipated levels and funding of capital expenditures. Forward-looking
statements are necessarily subject to risks, uncertainties and other factors,
many of which are outside the control of the Company, that could cause actual
results to differ materially from such statements. These uncertainties and other
factors include such things as: general business conditions, competitive
factors, including pricing pressures and product innovation and quality; raw
material availability and pricing; changes in the Company's relationships with
customers and suppliers; the ability of the Company to successfully integrate
recent and future acquisitions into its existing operations; changes in general
domestic economic conditions such as inflation rates, interest rates and tax
rates; increasingly stringent domestic and foreign governmental regulations
including those affecting the environment; inherent uncertainties involved in
assessing the Company's potential liability for environmental
remediation-related activities; the outcome of pending and future litigation and
other claims; dependence on the automotive industry; dependence on key
management; and dependence on information systems. Any forward-looking statement
speaks only as of the date on which such statement is made, and the Company
undertakes no obligation to update any forward-looking statement, whether as a
result of new information, future events or otherwise. In light of these and
other uncertainties, the inclusion of a forward-looking statement herein should
not be regarded as a representation by the Company that the Company's plans and
objectives will be achieved.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
Board of Directors and Shareholders
Park-Ohio Industries, Inc.
 
     We have audited the accompanying consolidated financial statements of
Park-Ohio Industries, Inc. and subsidiaries listed in the Index at Item
14(a)(1). 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 Park-Ohio
Industries, Inc. and subsidiaries at December 31, 1997 and 1996 and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1997 in conformity with generally
accepted accounting principles.

                        DECEMBER 31, 1997, 1996 AND 1995
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Consolidation: The consolidated financial statements include the accounts
of the Company and all of its subsidiaries. All significant intercompany
accounts and transactions have been eliminated upon consolidation.
 
     Accounting Estimates:  The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
     Cash Equivalents: The Company considers all highly liquid investments with
a maturity of three months or less when purchased to be cash equivalents.
 
     Inventories: Inventories are stated at the lower of cost (principally the
first-in, first-out method) or market value. If the first-in, first-out method
of inventory accounting had been used exclusively by the Company, inventories
would have been approximately $4,895 and $4,921 higher than reported at December
31, 1997 and 1996, respectively.

</TABLE>
 
     Property, Plant and Equipment: Property, plant and equipment are carried at
cost. Major additions are capitalized and betterments are charged to accumulated
depreciation; expenditures for repairs and maintenance are charged to
operations. Depreciation of fixed assets is computed principally by the
straight-line method based on the estimated useful lives of the assets.
 
     Excess Purchase Price Over Net Assets Acquired: The Company records
amortization of excess purchase price over the fair value of net assets acquired
(see Note B) over periods from twenty-five to forty years using the
straight-line method. Management periodically evaluates for possible impairment
the current value of these intangibles through cash flow and income analyses of
the acquired businesses. The Financial Accounting Standards Board's Statement of
Financial Accounting Standards No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of" establishes
accounting standards for determining the impairment of long-lived assets to be
held and used, certain identifiable intangibles, and goodwill related to those
assets and for long-lived assets and certain identifiable intangibles to be
disposed of. The company adopted Statement No. 121 during the first quarter of
1996. The financial statement effect of adoption was not material.
 
     Pensions: The Company and its subsidiaries have pension plans, principally
noncontributory defined benefit or noncontributory defined contribution plans,
covering substantially all employees. For the defined benefit plans, benefits
are based on the employee's years of service and the Company's policy is to fund
that amount recommended by its independent actuaries. For the defined
contribution plans, the costs charged to operations and the amount funded are
based upon a percentage of the covered employees' compensation.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     Stock-Based Compensation: The Company has elected to account for
stock-based compensation using the intrinsic value method prescribed in
Accounting Principles Board Opinion No. 25 "Accounting for Stock Issued to
Employees" ("APB 25"), and related interpretations. Under APB 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.
 
     Income Taxes: The Company accounts for income taxes under the liability
method whereby deferred tax assets and liabilities are determined based on
temporary differences between the financial reporting and the tax bases of
assets and liabilities and are measured using the current enacted tax rates.
 
     Net Income Per Common Share: In 1997, the Financial Accounting Standards
Board issued statement No. 128 "Earnings per Share". Statement 128 replaced the
calculation of primary and fully diluted earnings per share with basic and
diluted earnings per share. Unlike primary earnings per share, basic earnings
per share excludes any dilutive effects of options and convertible securities.
Diluted earnings per share is very similar to the previously reported fully
diluted earnings per share. All earnings per share amounts for all periods have
been presented, and where necessary restated to conform to the Statement 128
requirements.
 
     Interest Rate Swap Agreements: In 1995, the Company entered into interest
rate swap agreements to modify the interest characteristics of its outstanding
debt. Each interest rate swap agreement is designated with a portion of the
principal balance and term of a specific debt obligation. These agreements
involve the exchange of amounts based on a fixed interest rate for amounts based
on variable interest rates of the life of the agreement without an exchange of
the notional amount upon which the payments are based. The differential to be
paid or received as interest rates change is accrued and recognized as an
adjustment of interest expense related to the debt. During 1997, the interest
rate swap agreements were terminated resulting in an immaterial net gain.
 
     Revenue Recognition: For the majority of its operations, the Company
recognizes revenues upon shipment of its product. Revenues on long-term
contracts are recognized using the percentage of completion method of
accounting, under which the sales value of performance is recognized on the
basis of the percentage each contract's cost to date bears to the total
estimated cost. The recognition of profit, based upon anticipated final costs,
is made only after evaluation of the contract status at critical milestones. The
Company's contracts generally provide for billing to customers at various points
prior to contract completion. Revenues earned on contracts in process in excess
of billings are classified in other current assets in the accompanying balance
sheet.
 
     Environmental: The Company accrues environmental costs related to existing
conditions resulting from past or current operations and from which no current
or future benefit is discernible. Costs which extend the life of the related
property or mitigate or prevent future environmental contamination are
capitalized. The Company records a liability when environmental assessments
and/or remedial efforts are probable and can be reasonably estimated. The
estimated liability of the Company is not discounted or reduced for possible
recoveries from insurance carriers.
 
     Concentration of Credit Risk: The Company sells its products to customers
in diversified industries. The Company performs ongoing credit evaluations of
its customers' financial condition but does not require collateral to support
customer receivables. The Company establishes an allowance for doubtful accounts
based upon factors surrounding the credit risk of specific customers, historical
trends and other information. As of December 31, 1997 the Company had
uncollateralized receivables with six customers in the automotive and truck
industry each with several locations approximating $24,939 which represents 29%
of the Company's trade accounts receivable. During 1997, sales to these
customers amounted to approximately $121,443 which represents 28% of the
Company's net sales.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     Impact of Recently Issued Accounting Standards: In 1997, the Financial
Accounting Standards Board issued SFAS No. 130, "Reporting Comprehensive
Income," and SFAS No. 131, "Disclosures About Segments of an Enterprise and
Related Information," both of which expand or modify disclosures and,
accordingly, will have no impact on the Company's financial position, results of
operations or cash flows. These Statements are effective for periods beginning
after December 31, 1997, and will be adopted by the Company in the first and
fourth quarters of 1998, respectively.
 
NOTE B--ACQUISITIONS
 
     On August 1, 1997, the Company acquired substantially all of the shares of
Arden Industrial Products, Inc. ("Arden") for cash of approximately $44 million.
The transaction has been accounted for as a purchase. Arden is a national
distributor of specialty and standard fasteners to the industrial market. Arden
is included in the Company's Logistics segment.
 
     The following is the estimated value of the net assets of Arden as of
August 1, 1997:

     On January 14, 1998 the Company entered a new credit agreement with a group
of banks under which it may borrow up to $100 million on an unsecured basis.
Interest is payable quarterly at the prime lending rate less 1% (7.5% at
December 31, 1997) or at the Company's election at LIBOR plus .9% (which
aggregated 6.5% at December 31, 1997). The weighted average rate on borrowings
was 9.01% at December 31, 1997. The credit agreement expires on April 30, 2001.
The fair market value of debt securities approximates their carrying value at
December 31, 1997.
 
     Provisions of the Senior Subordinated Notes and the revolving credit
agreement contain restrictions on the Company's ability to incur additional
indebtedness, to create liens or other encumbrances, to make certain payments,
investments, loans and guarantees and to sell or otherwise dispose of a
substantial portion of assets to or merge or consolidate with, an unaffiliated
entity. The revolving credit agreement also requires maintenance of specific
financial ratios.
 
     The Company has agreements on which up to $5 million in standby letters of
credit and commercial letters of credit may be issued. In addition to the bank's
customary letter of credit fees, a  3/4% fee is assessed on standby letters of
credit on an annual basis. As of December 31, 1997, in addition to amounts
borrowed under the revolving credit agreement, there is $2.0 million outstanding
primarily for standby letters of credit. A fee of  1/4% is imposed by the bank
on the unused portion of available borrowings.

     At December 31, 1997, subsidiaries of the Company have net operating loss
carryforwards for income tax purposes of approximately $9.4 million subject to
certain limitations, which expire in 2001 to 2007. As of December 31, 1995, the

expected.
 
NOTE G -- STOCK OPTIONS
 
     Under the provisions of the Company's Amended and Restated 1992 Stock
Option Plan, incentive stock options or non-statutory options to purchase
850,000 shares of the Company's stock may be granted to officers and other key
employees at the market price on the respective date of grant. The option rights
are exercisable only if and after the employee shall have remained in the employ
of the Company for one year from the date the option is granted. During 1997,
30,000 options were granted at option prices ranging from $12.375--$14.50. No
options were granted in 1996. At December 31, 1997, there were a total of
355,000 options outstanding under the Plan (676,000 at December 31, 1996); all
of which become 100% exercisable after three years from the date of grant at
option prices ranging from $9.125--$14.50 ($3.813--$14.25 at December 31, 1996)
a share and terminate ten years from the option date. During 1997, 351,000
options under this Plan were exercised at prices ranging from $3.813--$13.625 a
share (31,167 at December 31, 1996 at prices ranging from $5.125--$10.625). At
December 31, 1997, there were 205,000 (348,992 at December 31, 1996) options
exercisable at option prices ranging from $9.125--$14.25 a share ($3.813--$14.25
at December 31, 1996).
 
     The 1996 Non-Employee Director Stock Option Plan authorized the granting of
options on 250,000 shares of common stock to directors who are not employees of
the Company. Annually, each non-employee director will automatically receive
options to acquire 6,000 shares at the market price on the date of grant.
Options under this plan are exercisable six months from the date of grant. At
December 31, 1997 there were 60,000 (30,000 at December 31, 1996) options
outstanding and exercisable under this plan at an exercise price ranging from
$12.41--$13.625. Also during 1996 the Chairman and Chief Executive Officer of
the Company was granted a non-statutory stock option to purchase 500,000 shares
of common stock at $13.625 per share which was the market price at the date of
grant. The options become 100% exercisable after five years and shall terminate
fifteen years from the option date. At December 31, 1997, 100,000 of these
options were exercisable.
 
     Had the compensation cost for the stock options granted in 1997, 1996 and
1995 been determined based on the fair value method of FASB Statement No. 123,
the Company's net income and earnings per share would have been reduced by
$1,304 ($.11 per share) in 1997, $1,290 ($.12 per share) in 1996 and $223 ($.02
per share) in 1995. The effects on 1997, 1996 and 1995 net earnings may not be
representative

of the effect on future years net earnings amounts as the compensation cost on
each year's grant is recognized over the vesting period.
 
     Fair value was estimated at the date of grant using a Black-Scholes option
pricing model with the following weighted-average assumptions for 1997, 1996 and
1995, respectively: risk-free interest rates of 5.25%, 5.25% and 6.34%; zero
dividend yield; expected volatility of 40% in 1997 and 43% in 1996 and 1995 and
expected option lives of 6 years for 1997, 6 to 10 years for 1996 and 6 years
for 1995.
 
NOTE H -- LEGAL PROCEEDINGS
 
     The Company is subject to various pending and threatened lawsuits in which
claims for monetary damages are asserted in the ordinary course of business.
While any litigation involves an element of uncertainty, in the opinion of
management, liabilities, if any, arising from currently pending or threatened
litigation will not have a material adverse effect on the Company's financial
condition, liquidity and results of operations.

     The accumulated postretirement benefit obligation ("APBO") was determined
using an assumed discount rate of 7.25%, 7.5% and 7.5% for 1997, 1996 and 1995,
respectively. The assumed annual health care trend rate for retirees younger
than 65 was 9.0% in 1997 (9.0% in 1996 and 9.5% in 1995) decreasing to 6.0% in
2004. The assumed annual health care trend rate for retirees aged 65 and over
will decrease to 5.5% in 2004. A 1% change in the trend rate would increase the
APBO by 6.3% and annual expense by 11%.
 
NOTE K -- LEASES
 
     Rental expense for 1997, 1996 and 1995 was $6,696, $4,751 and $3,527,
respectively. Future minimum lease commitments during each of the five years
following December 31, 1997 are as follows: $5,380 in 1998, $4,161 in 1999,
$3,272 in 2000, $2,625 in 2001 $1,915 in 2002 and $5,282 thereafter.
 
NOTE L -- INDUSTRY SEGMENTS
 
     The Company conducts its business through two segments: Manufactured
Products and Logistics. Manufactured Products designs and manufactures a broad
range of high quality products engineered for specific customer applications.
The principal customers of Manufactured Products are OEMs and end-users in the
automotive, railroad, truck and aerospace industries. Manufactured Products
operates through five groups which include: Aluminum Casting, Forged and
Machined Products, Capital Equipment, Metal Forming and Industrial Rubber
Products. The Aluminum Casting Group manufactures aluminum permanent mold
castings. The Forged and Machined Products Group produces, machines and finishes
closed-die metal forgings. The Capital Equipment Group custom engineers and
manufactures induction heating systems, forging presses and heat processing and
curing systems. The Metal Forming Group manufactures standard and specialty
engineered fasteners and related hardware bearings, plumbing fixtures and
certain consumer products. The Industrial Rubber Products Group manufactures
injected and transfer molded products, lathe-cut goods, roll coverings and
various items requiring rubber to metal bonding for use in industrial
applications. Logistics is a leading national supplier of fasteners (e.g., nuts,
bolts and screws) and other industrial products to OEMs, other manufacturers and
distributors. In connection with the supply of such industrial products,
Logistics provides a variety of value--added, cost-effective procurement
solutions. The principal customers of Logistics are in the transportation,
industrial, electrical, lawn and garden equipment industries.
 
     The Company's sales are made through its own sales organization,
distributors and representatives. Intersegment metal forming sales to the
Logistics segment are eliminated in consolidation and are not included in the
figures presented. Intersegment sales are accounted for at values based on
market prices. Income allocated to segments excludes interest expense and
amortization of excess purchase price over net assets acquired. Identifiable
assets by industry segment include assets directly identified with those
operations.

products lines. As a result of these actions, the Company recorded a charge of
$2,700 primarily for the writedown of certain property and equipment and
inventory to estimated net realizable value.
