             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
                               SEPTEMBER 30, 2000
                             (DOLLARS IN THOUSANDS)

NOTE A -- BASIS OF PRESENTATION

     The consolidated financial statements include the accounts of Park-Ohio
Industries, Inc. and its subsidiaries ("Park-Ohio," "the Company"). Park-Ohio is
a wholly-owned subsidiary of Park-Ohio Holdings Corp. as of June 10, 1998. All
significant intercompany transactions have been eliminated in consolidation.

     The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the three-month and nine-month periods
ended September 30, 2000 are not necessarily indicative of the results that may
be expected for the year ending December 31, 2000. For further information,
refer to the consolidated financial statements and footnotes thereto included in
the Company's Annual Report on Form 10-K for the year ended December 31, 1999.

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 and Bolt ("St. Louis Screw") and PMC
Industries, Inc. ("PMC") for cash. Metalloy is a full service aluminum casting
and machining company. Columbia and Industrial are logistics providers of "Class
C" production 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 September, 2000, the Company acquired IBM's Automation Connection
and SiView Mate software product lines and related assets for cash of
approximately $3.5 million. The transaction has been accounted for as a purchase
and the results of operations prior to the date of acquisition were not deemed
to be significant as defined in Regulation S-X.

     On June 30, 2000 the Company completed the sale of substantially all of the
assets of Kay Home Products for cash of approximately $9.2 million and recorded
a loss of approximately $15.3 million. Kay Home Products was a non-core business
producing and distributing barbecue grills, tray tables, screen houses and plant
stands.

NOTE D -- ACCOUNTING PRONOUNCEMENTS

     The Financial Accounting Standards Board's ("FASB") Statement of Financial
Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities" was issued in June 1998 and subsequently amended in June 2000, to
provide guidance on its implementation. Statement No. 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 No. 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.

     In December 1999, the staff of the Securities and Exchange Commission
("SEC") issued Staff Accounting Bulletin ("SAB") 101, "Revenue Recognition in
Financial Statements." SAB 101 outlines the basic criteria that must be met to
recognize revenue, and provides guidelines for disclosure related to revenue
recognition policies. This guidance is required to be implemented in the fourth
quarter of 2000. The Company is currently reviewing this guidance in order to
determine the impact of its provisions, if any, on the consolidated financial
statements.

     In March 2000, the FASB issued FASB Interpretation No. 44, "Accounting for
Certain Transactions Involving Stock Compensation: An Interpretation of APB
Opinion No. 25," which is effective July 1, 2000. This interpretation clarifies
various accounting issues for stock compensation plans. The Company has
determined that the interpretation will not have a significant effect on its
financial statements.

NOTE E -- SEGMENTS

     The Company manages its business based upon three operating segments:
Integrated Logistics Solutions ("ILS"), Aluminum Products and Manufactured
Products. ILS is a leading logistics provider of "Class C" production components
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, supply chain management solutions to major
OEMs. Aluminum Products manufactures cast aluminum components primarily for
automotive OEMs. In addition, 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. Intersegment sales are immaterial.

NOTE G -- INVOLUNTARY CONVERSION OF ASSETS

     On June 6, 2000, the Company experienced a fire at one of its manufacturing
facilities. The Company carries both property damage and business interruption
insurance, and as a result, does not expect the fire to have a material adverse
impact on the Company's financial results. The total amount due from the
insurance company for business interruption, property damage, and other related
expenses has not been determined. The deductible portion of the loss was
recorded during the quarter ended June 30, 2000. The Company has received a
partial settlement from its insurance carrier for certain machinery and
equipment and has recorded a gain of $4.7 million during the quarter ended
September 30, 2000. The net book value of the other property damaged by the fire
has been recorded as a receivable which is included in other current assets at
September 30, 2000.

                     INDEPENDENT ACCOUNTANTS' REVIEW REPORT

Board of Directors and Shareholders
Park-Ohio Industries, Inc.

     We have reviewed the accompanying consolidated balance sheet of Park-Ohio
Industries, Inc. and subsidiaries as of September 30, 2000, and the related
consolidated statements of income for the three-month and nine-month periods
ended September 30, 2000 and 1999, the consolidated statement of shareholder's
equity for the nine-month period ended September 30, 2000 and the consolidated
statements of cash flows for the nine-month periods ended September 30, 2000 and
1999. These financial statements are the responsibility of the Company's
management.

     We conducted our reviews in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical procedures to
financial data, and making inquiries of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit conducted in
accordance with auditing standards generally accepted in the United States,
which will be performed for the full year with the objective of expressing an
opinion regarding the financial statements taken as a whole. Accordingly, we do
not express such an opinion.

     Based upon our reviews, we are not aware of any material modifications that
should be made to the accompanying consolidated financial statements referred to
above for them to be in conformity with accounting principles generally accepted
in the United States.

     We have previously audited, in accordance with auditing standards generally
accepted in the United States, the consolidated balance sheet of Park-Ohio
Industries, Inc. and subsidiaries as of December 31, 1999 and the related
consolidated statements of income, shareholder's equity, and cash flows for the
year then ended, not presented herein, and in our report dated February 22,
2000, we expressed an unqualified opinion on those consolidated financial
statements. In our opinion, the information set forth in the accompanying
consolidated balance sheet as of December 31, 1999, is fairly stated, in all
material respects, in relation to the consolidated balance sheet from which it
is derived.

ITEM 2.  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., a wholly-owned subsidiary of Park-Ohio Holdings
Corp., and its subsidiaries. All significant intercompany transactions have been
eliminated in consolidation. The financial information for the nine and three-
month periods ended September 30, 2000 is not directly comparable on a
period-to-period basis to the financial information for the nine and three-month
periods ended September 30, 1999 due to a divestiture made subsequent to the
second quarter of 1999 and a gain recognized relating to fire insurance. On June
30, 2000, the Company sold substantially all the assets of Kay Home Products,
for cash of approximately $9.2 million and recorded a pretax loss of
approximately $15.3 million. In June 2000 one of the Company's manufacturing
plants was destroyed in a fire. A $4.7 million pretax gain was recognized, which
represented the difference between replacement cost and net book value of a
portion of equipment destroyed at the time of the fire.

OVERVIEW

     The Company has three operating segments: Integrated Logistics Solutions
("ILS"), Aluminum Products, and Manufactured Products. ILS is a leading
logistics provider of "Class C" production components 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 supply chain management solutions to major OEMs. 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.

     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% compound 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 $16.3 million.

     Recent growth has been primarily attributable to the Company's strategy of
making selective acquisitions in order to complement internal growth. In
addition, the Company has acquired under-performing 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 logistics service contracts and by the
leveraging of existing customer relationships in the Aluminum and Manufactured
Products segments.

RESULTS OF OPERATIONS

Nine Months 2000 versus Nine Months 1999

     Net sales increased by $45.4 million, or 8%, from $536.4 million for the
first three quarters of 1999 to $581.8 million for the first three quarters of
2000. Of the $45.4 million in growth for the first nine months $34.0 represented
organic growth $13.5 million was from acquisitions made in July, 1999, while
sales decreased by $2.1 million due to the divestiture of Kay Home Products. For
ILS, net sales increased 15%, or $48.3 million, of which $34.8 million related
to internal growth and the remainder to the acquisitions made in July 1999. For
Aluminum Products, net sales decreased 9%, or $8.5 million. This decrease
resulted from a $13.7 million decrease related to the ending of sales contracts
at Metalloy which were expected at the time of its purchase in 1999, partially
offset by $5.2 million increased sales from internal growth. For Manufactured
Products, net sales increased 5%, or $5.6 million, consisting of $7.7 million of
internal growth (7%) less a sales decrease of $2.1 million due to the
divestiture of Kay Home Products.

     Gross profit increased by $5.0 million, or 5%, from $96.3 million for the
first three quarters of 1999 to $101.3 million for the first three quarters of
2000. Of the increase in gross profit $1.0 million was attributable to the
organic increase in sales and $4.1 million to acquisitions offset by $.1 million
due to the divestiture of Kay Home Products. However, the Company's consolidated
gross margin decreased to 17.4% for the first nine months of 2000 from 18.0% for
the first nine months of 1999. This decrease in consolidated gross margin was
primarily due to decreased margins in Aluminum Products offset by an increase in
gross margins in the Manufactured Products segment. For Aluminum Products, the
decrease in gross margins related to the ending of sales contracts at Metalloy
which were expected at the time of its purchase in 1999, resulting in the
allocation of fixed manufacturing overhead over a smaller production base. The
increase in margins in the Manufactured Products segment resulted from increased
sales of higher margin products, particularly in the oil drilling capital
equipment business, and from increased production levels which allocated fixed
overhead costs over a larger productive base. These more than offset the gross
margin effects of a strike at one plant and the temporary shutdown of another
due to a fire, both of which occurred in the Manufactured Products segment.

     Selling, general and administrative ("SG&A") expenses increased by 5% to
$59.0 million for the first nine months of 2000 from $56.2 million for the first
nine months of 1999. The increase was related to increased sales and
acquisitions made in the second half of 1999, partially offset by the
divestiture of the Kay Home Products. Kay Home Products, divested on June 30,
2000, incurred $.8 million of SG&A expenses in the third quarter of 1999. In the
first three quarters of 2000, SG&A costs benefited from an increase in net
pension credits of $2.2 million, reflecting favorable investment returns on
pension plan assets. Consolidated SG&A expenses as a percentage of net sales
decreased to 10.1% for the first nine months of 2000 from 10.5% for the first
nine months of 1999.

     Interest expense increased by $5.1 million from $17.7 million for the first
nine months of 1999 to $22.8 million for the first nine months of 2000 due to
higher average debt outstanding during the current period and by higher average
interest rates in 2000 versus 1999. During the first nine months of 2000, the
Company averaged outstanding borrowings of $343.1 million as compared to $284.0
million for the first nine months of 1999. The $59.1 million increase related to
acquisitions in the preceding twelve months and to increases in working capital.
The average interest rate of 8.87% for the nine months ended September 30, 2000
was 55 basis points higher than the average rate of 8.32% for 1999. This rate
increase was due both to the $50 million add-on in June 1999 to the Company's
Senior Subordinated Notes at 9.25%, and to increased rates on the Company's
revolving credit facility primarily caused by Federal Reserve action.

     Before considering the tax effect of the divestiture of Kay Home Products
and the gain on fire insurance, the effective income tax rate for the nine-month
period ended September 30, 2000 was 41%, while for the nine months ended
September 30, 1999 it was 43%. The decrease in tax rate resulted from creating a
foreign sales corporation and to an increase in research and experimental
credits. The divestiture of Kay Home Products generated a book loss of $15.3
million, reducing income taxes by $2.1 million due to the exclusion of goodwill
for tax purposes. Income taxes of $1.9 million were provided for the $4.7
million pretax fire insurance gain. The Company's consolidated net income for
the first nine months of 2000 was therefore $1.2 million on consolidated income
before income taxes of $8.8 million.

Third Quarter 2000 versus Third Quarter 1999

     Net sales decreased by $7.2 million, or 4%, from $178.1 million for the
quarter ended September 30, 1999 to $170.9 million for the quarter ended
September 30, 2000. Of the $7.2 million decrease for the quarter, $5.1 million
represented organic decreases in sales, primarily in Aluminum Products, and $2.1
million resulted from the divestiture of Kay Home Products. For ILS, net sales
decreased 1%, or $.8 million, due to an approximate $.8 million decrease in
sales to the heavy truck market, mostly offset by growth in sales to other
markets. For Aluminum Products, net sales decreased 16%, or $4.8 million,
resulting from the ending of sales contracts at Metalloy which were expected at
the time of its purchase in 1999. For Manufactured Products, net sales decreased
4%, or $1.6 million, consisting of $.5 million internal growth less a sales
decrease of $2.1 million due to the divestiture of Kay Home Products.

     Gross profit decreased by $3.8 million, or 12%, from $31.5 million for the
quarter ended September 30, 1999 to $27.7 million for the quarter ended
September 30, 2000. Of the decrease in gross profit, $3.7 million represented
organic decreases in all three segments and the remainder to the divestiture of
Kay Home Products. The Company's consolidated gross margin decreased to 16.2%
for the current period from 17.7% for the quarter ended September 30, 1999.
Aluminum Products' gross margins declined due to decreased production volumes,
which allocated fixed overhead over a smaller production base. Manufactured
Products experienced increased margins compared to the year earlier period,
resulting primarily from a shift in product mix. This more than offset the gross
margin effects of a strike at one plant and the temporary shutdown of another
due to a fire, both of which occurred in the Manufactured Products segment.

     Selling, general and administrative ("SG&A") expenses decreased by 8% to
$16.7 million for the quarter ended September 30, 2000 from $18.0 million for
the quarter ended September 30, 1999. The decrease was related to decreased
sales and the divestiture of Kay Home Products. Kay Home Products, divested on
June 30, 2000, incurred $.8 million of SG&A expenses in the third quarter 1999.
In third quarter 2000, SG&A expenses benefited from an increase in net pension
credits of $.4 million, reflecting favorable investment returns on pension plan
assets. Consolidated SG&A expenses as a percentage of net sales decreased to
9.8% in third quarter 2000 from 10.1% in third quarter of 1999.

     Interest expense increased by $.9 million from $6.7 million in third
quarter 1999 to $7.6 million in the same period 2000 due to higher average debt
outstanding during the current period and higher average interest rates in 2000
versus 1999. For the quarter ended September 30, 2000, the Company averaged
outstanding borrowings of $338.0 million as compared to $308.0 million
outstanding for the quarter ended September 30, 1999. The $30.0 million increase
related to acquisitions in the preceding twelve months and to increases in
working capital. The average interest rate of 9.00% for third quarter 2000 was
35 basis points higher than the average rate of 8.65% in the same period of
1999. This rate increase was due to increased rates on the Company's revolving
credit facility primarily caused by Federal Reserve action.

     Before considering the tax effect of the gain on fire insurance, the
effective income tax rate for the quarter ended September 30, 2000 was 41%,
while for the quarter ended September 30, 1999 it was 43%. The decrease in tax
rate results from creating a foreign sales corporation and an increase in
research and experimental credits.

SEASONALITY; VARIABILITY OF OPERATING RESULTS

     As a result of the significant growth in our net sales and operating income
in recent years, seasonal fluctuations have been mitigated. However, the
Company's results of operations are typically stronger in the first six months
rather than the last six months of each calendar year due to scheduled plant
maintenance in the third quarter to coincide with customer plant shutdowns and
to holidays in the fourth quarter.

     The timing of orders placed by our 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 our business units.
This variability is particularly evident at the capital equipment businesses,
included in the Manufactured Products segment, which typically ship a few large
systems per year.
