ITEM 1. BUSINESS

THE COMPANY

     Park-Ohio Industries, Inc. ("Park-Ohio"), a wholly-owned subsidiary of
Park-Ohio Holdings Corp. ("Holdings"), was incorporated as an Ohio corporation
in January, 1985. Park-Ohio is a leading provider of logistics services and a
manufacturer of highly engineered products. Reference herein to the "Company"
includes, where applicable, Holdings, Park-Ohio and its direct and indirect
subsidiaries and its predecessor companies, which have operated for more than
150 years.

     The Company operates through three segments, Integrated Logistics Solutions
("ILS"), Aluminum Products and Manufactured Products, which serve a wide variety
of industrial markets. ILS is a leading national supplier of fasteners (e.g.,
nuts, bolts and screws) and other industrial products to original equipment
manufacturers ("OEMs"), other manufacturers and distributors. In connection with
the supply of such industrial products, ILS provides a variety of value-added,
cost-effective procurement solutions. The principal customers of ILS are OEMs in
the transportation, industrial, electrical and lawn and garden equipment
industries. Aluminum Products manufactures cast aluminum components primarily
for automotive OEMs. Aluminum Products also provides value-added services such
as design and engineering, machining and assembly. Manufactured Products is a
diverse group of manufacturing businesses that design and manufacture a broad
range of high quality products which includes capital equipment, rubber products
and forged and machined products for specific customer applications. The
principal customers of Manufactured Products are end-users in the automotive,
railroad, truck and aerospace industries. Between 1995 and 1999, the Company
grew significantly, through both internal growth and acquisitions. Over this
period, the Company's net sales increased from $289.5 million to $717.2 million,
income from continuing operations before income taxes increased from $12.9
million to $28.6 million, and EBITDA increased from $24.9 million to $72.1
million. As of December 31, 1999, the Company employed approximately 4,100
persons.

INTEGRATED LOGISTICS SOLUTIONS

     ILS is a leading national supplier of over 175,000 standard and specialty
fasteners and other industrial products pursuant to either supply chain
management agreements or traditional wholesale supply arrangements. ILS operates
out of branches located throughout the United States, Canada, Puerto Rico,
Mexico and England, and has a central distribution center located in Dayton,
Ohio. ILS generated net sales of $443.1 million, or 62% of the Company's net
sales for the year ended December 31, 1999. The four largest customers,
comprised of many divisions, accounted for approximately 23% of sales of ILS.
The loss of any one of these customers would have an adverse effect on this
segment.

     Products and Services. Supply chain management, which is ILS' 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
pursuant to total fastening services ("TFS") contracts. TFS contracts enable
ILS' 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
fasteners 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
61% of ILS' net sales for the year ended December 31, 1999. The increase in TFS
contracts has caused an increased investment in inventory in order to meet
customer just-in-time delivery requirements. ILS' 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.

     ILS supplies standard and specialty engineered fasteners such as nuts,
bolts, screws and washers on a fully integrated basis. ILS engineers and
manufactures precision cold formed and cold extruded products including
locknuts, SPAC(R) nuts and wheel hardware, which are principally used in
applications where controlled tightening is required due to high vibration.
These are manufactured by shaping cold raw materials. Standard and specialty
nuts are produced to customer specifications, which are used in large volumes by
customers in the automotive, truck and railroad industries.

     In addition to fasteners, ILS supplies, among other things, valves,
fittings, clamps and rubber products, which currently represent approximately
10% of ILS' net sales. ILS also provides engineering

                                        2
<PAGE>   4

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 1999, approximately 90% of ILS' net sales were to
domestic customers. Remaining sales were primarily to Canada and Mexico. The
domestic industrial fastener market is estimated by industry sources to have
generated between $7 and $9 billion in annual sales in 1999 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.

     ILS markets and sells fasteners and other industrial products to over
15,000 customers domestically and internationally. The principal markets served
by ILS are transportation equipment, including manufacturers of heavy trucks and
recreational vehicles; automotive parts and accessories; 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 industrial fastener
suppliers are consolidating as OEMs rely on fewer suppliers to achieve
purchasing efficiencies. ILS provides a wide array of value-added services and
is a reliable source for just-in-time delivery and is well 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 thereby allowing
ILS 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. Management believes that substantially all of ILS' competitors
operate on a regional basis and do not provide customers with the wide array of
supply chain management services offered by ILS. ILS competes primarily on the
basis of its value-added services, delivery capabilities, extensive product
selection and price with primarily domestic competitors who are capable of
providing inventory management programs.

ALUMINUM PRODUCTS

     In January, 1999 the Company acquired all of the shares of The Metalloy
Corporation ("Metalloy"). Metalloy is a full service aluminum casting and
machining company.

     The Aluminum Products segment generated net sales of $127.1 million, or 18%
of the Company's net sales for the year ended December 31, 1999. The three
largest customers, of which the Company sells to multiple operating divisions,
accounted for approximately 92% of Aluminum Products sales in 1999. The loss of
any one of these customers would have a material adverse effect on this segment.
Aluminum permanent mold, sand casted, and die casted products are produced at
Aluminum Products multiple locations in five states. Management believes
Aluminum Products is one of the few automotive part suppliers that has the
capabilities of providing permanent mold, sand-casted and die-casted products.

     Aluminum Products' cast aluminum parts are critical components manufactured
primarily for automotive OEMs. Aluminum Products' principal automotive products
include: transmission pump housings, intake manifolds, planetary pinion
carriers, oil filter adapters, clutch retainers, rotor castings and bearing
cups. In addition, Aluminum Products manufactures products for non-automotive
end users such as surgical table components, light housings and electrical meter
housings. Aluminum Products also provides value-added services such as secondary
casting, machining, drilling, tapping and part assembly. 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

                                        3
<PAGE>   5

castings 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. Aluminum Products sells
its products primarily to customers located in North America. The market for
aluminum castings is comprised of two segments: automotive and non-automotive.
The domestic aluminum castings industry is highly competitive. Aluminum Products
competes principally on the basis of its ability to: (i) engineer and
manufacture high quality, 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 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, Aluminum Products has benefited in recent years as automotive
OEMs have consolidated their supplier base.

MANUFACTURED PRODUCTS

     The Manufactured Products segment includes forged and machined products,
capital equipment, industrial rubber products and other manufactured products.
Manufactured Products generated net sales of $147 million, or 20% of the
Company's net sales for the year ended December 31, 1999. The three largest
customers, of which the Company sells to multiple operating divisions, accounted
for approximately 20% of Manufactured Products sales in 1999. The loss of
business from any one of these customers would have an adverse effect on this
segment.

     The Company's forged and machined products business is carried out at four
operating units consisting of Park Drop Forge, Ohio Crankshaft, Park-Ohio
Structural Hardware, and Blue Falcon Forge. The forging process enables metal to
be shaped while generally retaining higher structural integrity than metal
shaped through other processes. Park Drop Forge manufactures closed-die metal
forgings of up to 6,000 pounds, including crankshafts and aircraft landing
gears, primarily for customers in the railroad and aerospace industries. Park
Drop Forge's products are sold primarily to machining companies, including Ohio
Crankshaft and subassemblers who finish the products for sale to OEMs in the
railroad and aerospace industries. Ohio Crankshaft machines, induction hardens
and surface finishes crankshafts and camshafts used primarily in locomotives,
power generators and ships. Park-Ohio Structural Hardware manufactures and
machines specialized hardware such as turnbuckles and clevises for construction
companies. Its products are manufactured according to customers' specific
dimensional and/or strength requirements. Blue Falcon Forge produces large
forged products such as center plates and couplings, both of which are used in
the undercarriage of rail cars. Forged and machined products are sold to a wide
variety of domestic and international OEMs and other manufacturers in the
transportation, power generation and construction industries. The Company's
forged and machined products business competes domestically and internationally
with other small to medium-sized businesses on the basis of product quality and
precision.

     The Company manufactures large industrial equipment through its operating
units consisting of Tocco, Ajax, Feco and PMC-Colinet. Tocco specializes in the
engineering and construction of induction heating systems primarily for the
automotive and truck industries. Tocco's induction heating systems are
engineered and built to customer specifications and are used primarily by OEMs
for surface hardening. Ajax engineers, manufactures and services mechanical
forging presses ranging in size from 500 to 8,000 tons that are used worldwide
in the automotive and truck manufacturing industries. Feco produces complete
oven systems that combine heat processing and curing technologies with material
handling and conveying methods. Feco's principal products include industrial
drying and curing ovens for automotive components, metal can curing ovens,
specialized conveyor and automation systems for lightweight containers, and
plastic and glass bottle coating and finishing systems. PMC-Colinet produces
tube threading machines and related parts for the oil drilling industry. The
Company's capital equipment units compete with large domestic and international
equipment manufacturers on the basis of service capability, ability to meet
customer specifications, delivery performance and engineering expertise.

                                        4
<PAGE>   6

     The Company manufactures injection and transfer molded products, lathe-cut
goods, roll coverings and various items requiring rubber to metal bonding for
use in industrial applications through three operating units consisting of
Castle Rubber, Cicero Flexible Products and Geneva Rubber. Castle manufactures
valve seals, power and conveyor rolls and slitter rings. Cicero is a developer
and manufacturer of injection molded silicone rubber products for customers in
the automotive, food processing and consumer appliance industries, such as wire
harnesses, spark plug boots and nipples and general sealing gaskets. Geneva is a
manufacturer of injection molded rubber products for customers in the
automotive, telecommunications and heavy truck industries. Its products include
primary wire harnesses, transoceanic cable boots and shock and vibration mounts.
The industrial rubber products operating units compete primarily on the basis of
price and product quality with other domestic small to medium-sized
manufacturers of rubber products.

SALES AND MARKETING

     ILS 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. ILS often obtains new customers as a result of referrals from
existing customers. Aluminum Products and 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, Manufactured Products markets certain
of its products through various regional and national trade shows.

RAW MATERIALS AND SUPPLIERS

     ILS purchases substantially all of its fasteners from third party
suppliers. Aluminum Products and Manufactured Products purchase substantially
all of their raw materials, principally metals and certain component parts
incorporated into their products, from third-party suppliers and manufacturers.
Management believes that raw materials and component parts other than certain
specialty fasteners are available from alternative sources. ILS has multiple
sources of supply for standard products, but has limited supply sources for
certain specialty products. Approximately 12% of ILS' 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. Most raw
materials required by Aluminum Products and Manufactured Products are commodity
products available from several domestic suppliers.

BACKLOG

     Management believes that backlog is not a meaningful measure for ILS, as a
majority of ILS' customers require just-in-time delivery of fasteners and other
industrial products. Management believes that Aluminum Products' and
Manufactured Products' backlog as of any particular date is not a meaningful
measure of sales for any future period as a significant portion of sales are on
a release or firm order basis.

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

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. 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. 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.

        OF OPERATIONS

     Certain information required by this item has been omitted pursuant to
General Instruction I of Form 10-K.

     The consolidated financial statements of the Company include the accounts
of Park-Ohio Industries, Inc. and its subsidiaries. All significant intercompany
transactions have been eliminated in consolidation. The historical financial
information is not directly comparable on a year-to-year basis due to
acquisitions made in 1999 and 1998. During 1999, the Company acquired six
businesses for an aggregate purchase price of $65.4 million. In January, the
Company acquired all of the shares of The Metalloy Corporation ("Metalloy") and
substantially all of the assets of St. Louis Screw & Bolt Co. ("St. Louis
Screw"). Metalloy is a full service aluminum casting and machining company. St.
Louis Screw is a manufacturer of bolts used in the construction industry. In
February, the Company acquired substantially all of the assets of PMC
Industries, ("PMC") and, in September, the Company acquired all of the shares of
M.P. Colinet ("Colinet"). PMC and Colinet provide capital equipment and
associated parts for the oil drilling industry. In July, the Company acquired
all of the shares of Columbia Nut and Bolt Corp. ("Columbia") and Industrial
Fasteners Corporation ("Industrial"). Columbia and Industrial are logistics
providers of fastener related components. During 1998, the Company acquired two
businesses for $40.2 million. In October, the Company acquired all of the shares
of GIS Industries, Inc. ("Gateway"). Gateway is a logistics provider of
fastener-related components and a manufacturer of metal products and fasteners.
In April, the Company acquired all of the shares of Direct Fasteners Limited
("Direct"), a logistics provider of fastener related components located in
Ontario, Canada. Each of these transactions has been accounted for as a purchase
and consequently their results are included in the consolidated financial
statements from their respective dates of acquisition.

OVERVIEW

     The Company operates diversified manufacturing and logistics businesses
that serve a wide variety of industrial markets. During the first quarter of
1999 the Company, upon completion of the acquisition of Metalloy, redefined and
restated its operating segments. The Company manages its businesses based upon
three operating segments: Integrated Logistics Solutions ("ILS"), Aluminum
Products and Manufactured Products. ILS is a leading national supplier of
fasteners (e.g., nuts, bolts and screws) and other industrial products to
original equipment manufacturers ("OEMs"), other manufacturers and distributors.
In connection with the supply of such industrial products, ILS provides a
variety of value-added, cost-effective procurement solutions. The principal
customers of ILS are in the transportation, industrial, electrical and lawn and
garden equipment industries. Aluminum Products manufactures cast aluminum
components primarily for automotive OEMs. Aluminum Products also provides
value-added services such as design and engineering, machining and assembly.
Manufactured Products operates a diverse group of niche manufacturing businesses
that design and manufacture 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.

<PAGE>   9

     Between 1993 and 1999, the Company has grown significantly, both internally
and through acquisitions. Over this period, the Company's net sales increased at
a 40% compounded annual growth rate ("CAGR"), from $94.5 million to $717.2
million, and income from continuing operations on a fully taxed basis increased
at a 38% CAGR from $2.4 million to $16.4 million.

     Recent growth has been primarily attributable to the Company's strategy of
making selective acquisitions in order to complement internal growth. The
Company has acquired 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 ILS customers under
total fastening service ("TFS") contracts and by the leveraging of existing
customer relationships in the Aluminum and Manufactured Products segments.

     Between January 1, 1994 and December 31, 1999, the Company's continuing
operations incurred $86.9 million of capital expenditures, the majority of which
was used to expand existing manufacturing facilities, upgrade equipment and
enhance the Company's management information systems.

RESULTS OF OPERATIONS

       1999 versus 1998

     Net sales increased by $165.4 million, or 30%, from $551.8 million in 1998
to $717.2 million in 1999. This growth results primarily from recent
acquisitions and relates to the ILS and the Aluminum Products segments. For ILS,
the growth in net sales amounted to $78.5 million of which $51.7 million related
to acquisitions and the remainder was organic growth. For Aluminum Products, net
sales increased by $87.3 million of which $81.2 million related to the
acquisition of Metalloy and the remainder to internal growth.

     Gross profit increased by $29.2 million, or 30%, from $96.6 million in 1998
to $125.8 million in 1999 and is directly related to acquisitions made in 1999.
The Company's consolidated gross margin of approximately 17.5% was the same for
both periods.

     Selling, general and administrative costs increased by 29% to $72.4 million
for 1999 from $56.3 million for 1998. The increase was related to recent
acquisitions. Consolidated selling, general and administrative expenses as a
percentage of net sales were 10.1% during the current period and 10.2% for 1998.

     Interest expense increased by $7.3 million from $17.5 million in 1998 to
$24.8 million in 1999 due to higher average debt outstanding during the current
period offset by lower average interest rates in 1999 versus 1998. For the year
ended December 31, 1999, the Company averaged outstanding borrowings of $294.6
million as compared to $205.3 million for 1998. The $89.3 million increase
related primarily to acquisitions completed during the latter part of 1998 and
in 1999. The average borrowing rate of 8.40% for the year ended December 31,
1999 is 12 basis points lower than the average rate of 8.52% for 1998 primarily
because of increased borrowings under the Company's bank revolving credit which
carries a lower effective interest rate as compared to the 9.25% on the
Company's Senior Subordinated Notes.

     The effective income tax rate for 1999 and 1998 was 43%. At December 31,
1999, subsidiaries of the Company had $1.1 million of net operating loss
carryforwards for federal tax purposes.

  1998 versus 1997

     Net sales increased by $110.7 million, or 25%, from $441.1 million in 1997
to $551.8 million in 1998. Approximately 27% of this increase was attributable
to internal growth and 73% was a result of acquisitions completed in 1997 or
1998. Of the internal sales growth, approximately 66% was primarily attributable
to ILS and the addition of TFS customers, and the remainder was due to increased
orders from Aluminum Products' (11%) and Manufactured Products' (23%) customers.
The growth in net sales from acquisitions applies to ILS and primarily pertains
to Arden and Gateway.

     Gross profit increased by $24.2 million, or 33%, from $72.4 million in 1997
to $96.6 million in 1998. Of the increase, 67% relates to acquisitions and 33%
to internal growth. The Company's consolidated
                                        8
<PAGE>   10

gross margin increased to 17.5% for 1998 from 16.4% for 1997. This increase in
consolidated gross margin was due to increased margins in both the ILS and
Manufactured Products segments offset by a decrease in Aluminum Products
margins. The increase in margin in Manufactured Products was due to a change in
revenue mix and to increased production thereby allocating fixed manufacturing
overhead over a greater production base. The increase in margins in the ILS
segment is a result of reduced material costs. The decrease in margin in
Aluminum Products was the result of higher than expected start-up costs
associated with new facilities necessitated by significant new orders from a
major customer.

     Selling, general and administrative costs increased by 27% to $56.3 million
in 1998 from $44.4 million in 1997. Approximately 78% of such increase was
related to acquisitions while the remainder related to the increase in
internally generated net sales. During 1998, selling, general and administrative
expenses benefited from an increase in net pension credits of $2.4 million,
reflecting favorable investment returns on pension plan assets. Consolidated
selling, general and administrative expenses as a percentage of net sales was
approximately 10% for both periods.

     Interest expense increased by $8.4 million from $9.1 million for 1997 to
$17.5 million for 1998 due to higher average debt outstanding during 1998 and to
higher average interest rates in 1998 versus 1997. For the year ended December
31, 1998, the Company averaged outstanding borrowings of $205.3 million as
compared to $123.1 million outstanding for 1997. The $82.2 million increase
related primarily to acquisitions completed during the latter part of 1997 and
1998, working capital increases to support the realized and anticipated growth
in business and capital expenditures to support the operations. The average
borrowing rate of 8.5% for the year ended December 31, 1998 is 1.1% higher than
the average rate of 7.4% for the year ended December 31, 1997 primarily because
of the $150 million bond offering in November, 1997 which carries a rate of
9.25% versus a 7.3% rate on the bank debt it replaced.

     The effective income tax rate for 1998 was 43% as compared to 41% for 1997.
The increase is directly attributable to an increase in expenses recorded for
financial reporting purposes, but not deductible for income tax purposes,
primarily certain goodwill amortization. At December 31, 1998, subsidiaries of
the Company had $1.1 million of net operating loss carryforwards for tax
purposes.

SEASONALITY; VARIABILITY OF OPERATING RESULTS

     As a result of the significant growth in the Company's net sales and
operating income in recent years, seasonal fluctuations have been substantially
mitigated. The Company, however, performs scheduled plant maintenance in the
third quarter to coincide with customer plant shut downs.

     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
capital equipment businesses, included in the Manufactured Products segment,
which typically ship a few large systems per year.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

     The Company is exposed to market risk including changes in interest rates.
The Company is subject to interest rate risk on its floating rate revolving
credit facility which consisted of borrowings of $138 million at December 31,
1999. A 100 basis point increase in the interest rate would have resulted in an
increase in interest expense of approximately $1.2 million for the year ended
December 31, 1999.

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

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                        DECEMBER 31, 1999, 1998 AND 1997
                 (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 $5,098 and $4,869 higher than reported at December
31, 1999 and 1998, respectively.

</TABLE>

     Property, Plant and Equipment: Property, plant and equipment are carried at
cost. Major additions and associated interest costs 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. The Company capitalized interest of $1.0 million in 1998.
Interest capitalized in 1999 and 1997 was immaterial.

     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
of the current value of these intangibles, and other long-lived assets, through
undiscounted cash flow analyses as required by 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"
which established 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. Amortization expense related to the
excess purchase price over net assets acquired totalled $3,835, $2,356 and
$2,211 in 1999, 1998 and 1997, respectively.

     Pensions and Other Postretirement Benefits: The Company and its
subsidiaries have pension plans, principally noncontributory defined benefit or
noncontributory defined contribution plans, cover-

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED

ing substantially all employees. In addition, the Company has two postretirement
benefit plans. 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.

     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.

     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, 1999 the Company had
uncollateralized receivables with seven customers in the automotive and truck
industry, each with several locations, approximating $34,176 which represents
approximately 30% of the Company's trade accounts receivable. During 1999, sales
to these customers amounted to approximately $245,588 which represents 34% of
the Company's net sales.

     Impact of Recently Issued Accounting Standards: In March 1998, the American
Institute of Certified Public Accountants ("AICPA") issued Statement of Position
("SOP") 98-1, "Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use". The SOP requires companies to capitalize qualifying
computer software costs incurred during the application development stage. The
Company adopted the statement in the first quarter of 1999. The impact of this
new standard did not have a significant effect on the Company's financial
position or results of operations.

     In April 1998, the AICPA issued SOP 98-5, "Accounting for the Costs of
Start-up Activities". The SOP requires that costs of start-up activities be
expensed as incurred. The SOP is effective for fiscal years beginning after
December 15, 1998. The Company adopted the SOP in the first quarter of 1999. The
                                       18

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED

impact of adoption of the SOP on the Company's financial position, results of
operations or cash flows was immaterial.

     The Financial Accounting Standards Board's Statement of Financial
Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities" was issued in June 1998. Statement 133 requires derivatives to be
recorded on the balance sheet at fair value and establishes accounting for three
different types of hedges: hedges of changes in fair value of assets,
liabilities, or firm commitments; hedges of the variable cash flows of
forecasted transactions; and hedges of foreign currency exposures of net
investments in foreign operations. Statement 133 is effective for years
beginning after June 15, 2000 and is not expected to have a significant impact
on the Company's financial position or results of operations.

     Reclassification: Certain amounts in the prior period's financial
statements have been reclassified to be consistent with the current
presentation.

NOTE B -- ACQUISITIONS AND DISPOSITION

     During 1999, the Company acquired all of the stock of The Metalloy
Corporation ("Metalloy"), Columbia Nut and Bolt Corp. ("Columbia"), Industrial
Fasteners Corporation ("Industrial"), M.P. Colinet ("Colinet") and substantially
all of the assets of St. Louis Screw & Bolt Co. ("St. Louis Screw") and PMC
Industries ("PMC") for cash of approximately $65.4 million. Metalloy is a full
service aluminum casting and machining company. Columbia and Industrial are
logistics providers of fastener related components. St. Louis Screw is a
manufacturer of bolts and PMC and Colinet provide capital equipment and
associated parts for the oil drilling industry. Each of these transactions has
been accounted for as a purchase. The purchase price and the results of
operations of each of these businesses prior to their respective dates of
acquisition were not deemed to be significant as defined in Regulation S-X.

     During 1998, the Company completed the acquisitions of Direct Fasteners
Limited ("Direct") and GIS Industries, Inc. ("Gateway"). The transactions have
been accounted for as purchases. Direct is a logistics provider of fastener
related components. Gateway is a logistics provider of fastener related
components and manufacturer of fabricated metal products and fasteners. The
aggregate purchase price and the results of operations of Direct and Gateway
prior to their respective dates of acquisition were not deemed to be significant
as defined in Regulation S-X.

     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 ILS segment.

     The following is the estimated value of the net assets of Arden as of
August 1, 1997:

     During the year ended December 31, 1997, the Company acquired four other
businesses for an aggregate purchase price of approximately $18.6 million. Each
of these transactions was accounted for as a purchase, resulting in excess
purchase price over net assets acquired of $8.6 million. The following unaudited
pro forma results of operations assume the acquisitions of Arden and the other
businesses discussed above occurred on January 1, 1997. These pro forma results
have been prepared for comparative purposes only and do not purport to be

     During 1999 Park-Ohio amended its credit agreement with a group of banks
under which it may borrow up to $175 million on an unsecured basis. Interest is
payable quarterly at the prime lending rate (8.5% at December 31, 1999) less 1%
to plus .2% or at Park-Ohio's election at LIBOR plus .9% to 2.2% (which
aggregated 7.5% at December 31, 1999). The interest rate is dependent on the
aggregate amounts borrowed under the agreement. The credit agreement expires on
April 30, 2001.

     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.

     On November 25, 1997, the Company sold $150 million of its 9.25% Senior
Subordinated Notes due 2007 at a price of 97.375% of face value. Interest on the
Senior Subordinated Notes is payable semi-annually on June 1 and December 1 of
each year beginning on June 1, 1998. The Company used the net proceeds of the
Senior Subordinated 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. The early extinguishment of the 7 1/4% Convertible Senior Subordinated
Debentures and the then existing credit facility resulted in an extraordinary
charge of $1.5 million consisting of the following:

customary letter of credit fees, a 3/4% fee is assessed on standby letters of
credit on an annual basis. As of December 31, 1999, in addition to amounts
borrowed under the revolving credit agreement, there is $2.9 million outstanding
primarily for standby letters of credit. A fee of 1/4% to 3/8% is imposed by the
bank on the unused portion of available borrowings.

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.

NOTE H -- LEASES

     Rental expense for 1999, 1998 and 1997 was $11,814, $7,056 and $6,696,
respectively. Future minimum lease commitments during each of the five years
following December 31, 1999 are as follows: $10,128 in 2000, $8,318 in 2001,
$5,863 in 2002, $3,950 in 2003, $1,810 in 2004 and $3,853 thereafter.

NOTE I -- INDUSTRY SEGMENTS

     During the first quarter of 1999 the Company, upon completion of the
acquisition of Metalloy, redefined and restated its operating segments. The
Company retained its Integrated Logistics Solutions ("ILS") segment and further
segregated its former Manufactured Products segment into an Aluminum Products
segment and a Manufactured Products segment. ILS is a leading national supplier
of fasteners (e.g., nuts, bolts and screws) and other industrial products to
original equipment manufacturers, other manufacturers and distributors. In
connection with the supply of such industrial products, ILS provides a variety
of value-added, cost-effective procurement solutions. The principal customers of
ILS are in the transportation, industrial, electrical, lawn and garden equipment
industries. Aluminum Products manufactures cast aluminum components primarily
for automotive original equipment manufacturers. In addition, Aluminum Products
also provides value-added services such as design and engineering, machining and
assembly. Manufactured Products designs and manufactures a broad range of high
quality products which includes capital equipment, rubber products and forged
and machined products for specific customer applications. The principal
customers of Manufactured Products are original equipment manufacturers and
end-users in the automotive, railroad, truck and aerospace industries.

     The Company's sales are made through its own sales organization,
distributors and representatives. Intersegment sales are immaterial and
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 certain corporate expenses, interest expense and
amortization of excess purchase price over net assets acquired. Identifiable
assets by industry segment include assets directly identified with those
operations.

     Corporate assets generally consist of cash and cash equivalents, deferred
tax assets, and other assets.
