                  PARK-OHIO INDUSTRIES, INC. AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
                                 JUNE 30, 2003
                             (AMOUNTS 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 accounting principles generally accepted 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 accounting principles generally accepted in the United
States 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
six-month periods ended June 30, 2003 are not necessarily indicative of the
results that may be expected for the year ending December 31, 2003. 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, 2002.

     Certain amounts have been reclassified to conform to current year
presentation.

NOTE B -- ACCOUNTING CHANGE

     As described in Note A to the consolidated financial statements for the
year ended December 31, 2002, inventories are stated at the lower of cost or
market value. The first-in, first-out (FIFO) method was used to determine cost
for 85% of inventories and the last-in, first-out (LIFO) method was used to
determine cost for the remaining 15% of inventories.

     Effective June 30, 2003, the Company changed the method of accounting for
the 15% of its inventories utilizing the LIFO method to the FIFO method. The
Company believes that this change is preferable for the following reasons: 1)
the change conforms all of its inventories to one method of determining cost,
which is the FIFO method; 2) the costs of the Company's inventories have
remained fairly level during the past several years, which has substantially
negated the benefits of the LIFO method (a better matching of current costs with
current revenues in periods of rising costs); 3) the impact of utilizing the
LIFO method has had an insignificant impact on the Company's consolidated net
income (loss) during the past several years; and 4) the FIFO method results in
the valuation of inventories at current costs on the consolidated balance sheet,
which provides a more meaningful presentation for investors and financial
institutions.

     As required under accounting principles generally accepted in the United
States, the Company has restated the consolidated balance sheet as of December
31, 2002 to increase inventories by the recorded LIFO reserve ($4.4 million),
increase deferred tax liabilities ($1.7 million), and increase shareholders'
equity ($2.7 million). Previously reported results of operations have not been
restated because the impact of utilizing the LIFO method had an insignificant
impact on the Company's reported amounts for consolidated net income (loss).

NOTE C -- ACQUISITION AND DISPOSITIONS

     During the first quarter of 2003, the Company completed the sale of
substantially all of the assets of Green Bearing ("Green") and St. Louis Screw
and Bolt ("St. Louis Screw") for cash of approximately $7.3 million. No gain or
loss was recorded on the sale. Green and St. Louis Screw were non-core
businesses in the ILS Segment and Manufactured Products Segment, respectively,
and had been identified as businesses the Company was selling as part of its
restructuring activities during 2002 and 2001.

     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)

     On September 10, 2002, the Company acquired substantially all of the assets
of Ajax Magnethermic Corporation ("Ajax"), a manufacturer of induction heating
and melting equipment. The purchase price of approximately $5.5 million and the
results of operations of Ajax prior to its date of acquisition were not deemed
significant as defined in Regulation S-X.

     On April 26, 2002, the Company completed the sale of substantially all of
the assets of Castle Rubber Company for cash of approximately $2.5 million.
Castle Rubber, a non-core business in the Manufactured Products Segment, had
been identified as a business the Company was discontinuing as part of its
restructuring activities during 2001.

NOTE D -- INVENTORIES

     The components of inventory consist of the following:

NOTE E -- ADOPTION OF FAS 142 "GOODWILL AND OTHER INTANGIBLE ASSETS"

     Effective January 1, 2002, the Company adopted FAS 142, "Goodwill and Other
Intangible Assets". Under this standard, goodwill is no longer amortized but is
subject to an impairment test at least annually. The Company has selected
October 1 as its annual testing date.

     The Company, with the assistance of an outside consultant, completed the
transitional impairment review of goodwill during the fourth quarter of 2002 and
recorded a non-cash charge for goodwill impairment which aggregated $48,799. In
accordance with the provisions of FAS 142, the charge has been accounted for as
a cumulative effect of a change in accounting principle, retroactive to January
1, 2002.

NOTE F -- ACCOUNTING PRONOUNCEMENTS

     In June 2002, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 146, "Accounting for Costs
Associated with Exit or Disposal Activities," ("FAS 146"), which addresses
financial accounting and reporting for costs associated with exit or disposal
activities and nullifies Emerging Issues Task Force (EITF) Issue No. 94-3,
"Liability Recognition for Certain Employee Termination Benefits and Other Costs
to Exit an Activity (including Certain Costs Incurred in a Restructuring)." FAS
146 requires that a liability for a cost that is associated with an exit or
disposal activity be recognized when a legal liability is incurred. FAS 146 is
effective for exit and disposal activities that are initiated after December 31,
2002.

     In November 2002, the FASB issued Interpretation No. 45, "Guarantor's
Accounting and Disclosure Requirements for Guarantees, Including Indirect
Guarantees of Indebtedness of Others" ("FIN 45"). FIN 45 elaborates on required
disclosures by a guarantor in its financial statements about obligations under
certain guarantees that it has issued and requires a guarantor to recognize, at
the inception of certain guarantees, a liability for the fair value of the
obligation undertaken in issuing the guarantee. The Company is reviewing the
provisions of FIN 45 relating to initial recognition and measurements of
guarantor liabilities, which are effective for qualifying guarantees entered
into or modified after December 31, 2002, but does not expect the adoption to
have a material impact on the consolidated financial statements. The Company
adopted the new disclosure requirements for the year ended December 31, 2002.

     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) -- (CONTINUED)

     In January 2003, the FASB issued Interpretation No. 46 ("FIN 46"),
"Consolidation of Variable Interest Entities," which clarifies the application
of Accounting Research Bulletin ("ARB") No. 51, "Consolidated Financial
Statements," relating to consolidation of certain entities. First, FIN 46 will
require identification of the Company's participation in variable interest
entities ("VIEs"), which are defined as entities with a level of invested equity
that is not sufficient to fund future activities to permit them to operate on a
stand alone basis, or whose equity holders lack certain characteristics of a
controlling financial interest. Then, for entities identified as VIEs, FIN 46
sets forth a model to evaluate potential consolidation based on an assessment of
which party to the VIE, if any, bears a majority of the exposure to its expected
losses, or stands to gain from a majority of its expected returns. FIN 46 is
effective for all new VIEs created or acquired after January 31, 2003. For VIEs
created or acquired prior to February 1, 2003, the provisions of FIN 46 must be
applied for the first interim or annual period beginning after June 15, 2003.
FIN 46 also sets forth certain disclosures regarding interests in VIEs that are
deemed significant, even if consolidation is not required. The Company is
currently evaluating the effect that the adoption of FIN 46 will have on its
financial position, results of operations and cash flows.

     In April 2003, the FASB issued Statement of Financial Accounting Standards
No. 149, "Amendment of Statement 133 on Derivative Instruments and Hedging
Activities ("FAS 149"). FAS 149 amends and clarifies the accounting for
derivative instruments, including certain derivative instruments embedded in
other contracts, and for hedging activities under FAS 133, "Accounting for
Derivative Instruments and Hedging Activities." FAS 149 is generally effective
for contracts entered into or modified after June 30, 2003 and for hedging
relationships designated after June 30, 2003. The Company is currently
evaluating whether or not the adoption of FAS 149 will have an effect on its
financial position, results of operations and cash flows.

     In May 2003, the FASB issued Statement of Financial Accounting Standards
No. 150, "Accounting for Certain Financial Instruments with Characteristics of
both Liabilities and Equity ("FAS 150"). FAS 150 requires that certain financial
instruments, which under previous guidance were accounted for as equity, must
now be accounted for as liabilities. The financial instruments affected include
mandatorily redeemable stock, certain financial instruments that require or may
require the issuer to buy back some of its shares in exchange for cash or other
assets and certain obligations that can be settled with shares of stock. FAS 150
is effective for all financial instruments entered into or modified after May
31, 2003 and must be applied to the Company's existing financial instruments
effective July 1, 2003, the beginning of the first fiscal period after June 15,
2003. The Company adopted FAS 150 on June 1, 2003. The adoption of this
statement did not have a material effect on the Company's financial position,
results of operations or cash flows.

NOTE I -- RESTRUCTURING ACTIVITIES

     The Company responded to the economic downturn by reducing costs in a
variety of ways, including restructuring businesses and selling non-core
manufacturing assets. These activities, which included asset write-downs and
other exit costs related to the shutdown of facilities, generated restructuring
and asset impairment charges of $19.2 million and $28.5 million in 2002 and
2001, respectively (of which $5.6 million (490 employees) in 2002 and $6.9
million (525 employees) in 2001 related to severance and exit costs). For
further details on the restructuring plan, see Note L to the audited financial
statements contained in the Company's Annual Report on Form 10-K for the year
ended December 31, 2002.

     During the first quarter of 2003, the Company completed the sale of
substantially all of the assets of Green Bearing and St. Louis Screw and Bolt
for cash of approximately $7.3 million. No gain or loss was recorded on these
sales. Both of these businesses had been identified as businesses the Company
was selling as part of its restructuring activities.

     The accrued liability balance for severance and exit costs and related cash
payments consisted of:

</Table>

     As of June 30, 2003, all of the 525 employees identified in 2001 and all
but 29 of the 490 employees identified in 2002 had been terminated. The
workforce reductions under the restructuring plan consisted of hourly and
salaried employees at various operating facilities due to either closure or
consolidation.

     Net sales for the businesses that were included in net assets held for sale
were $7,129 and $10,167 for the six months ended June 30, 2003 and 2002,
respectively. Operating income for these entities was $23 and $66 for the six
months ended June 30, 2003 and 2002, respectively.

NOTE K -- INCOME TAXES

     The effective income tax rate for the three-month period ended June 30,
2003 was 24%, compared to 40% for the corresponding period in 2002. Only foreign
and state income taxes were provided for in 2003, because federal income taxes
were eliminated due to the recognition of net operating loss carryforwards for
which valuation allowances had been provided for prior to 2003. At December 31,
2002, the Company had net operating loss carryforwards of approximately $25.6
million. Tax benefits related to these carryforwards were fully reserved in
2002, because the Company was in a three-year cumulative loss position.

NOTE L -- DEBT RESTRUCTURING

     The revolving credit maturing on June 30, 2004 was refinanced and repaid in
its entirety by the Company on July 30, 2003 with a new revolving credit
facility which matures on July 30, 2007 and is classified as long-term debt.

                     INDEPENDENT ACCOUNTANTS' REVIEW REPORT

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

     We have reviewed the accompanying consolidated balance sheet of Park-Ohio
Industries, Inc. and subsidiaries as of June 30, 2003 and the related
consolidated statements of operations for the three-month and six-month periods
ended June 30, 2003 and 2002, the consolidated statement of shareholder's equity
for the six-month period ended June 30, 2003 and the consolidated statements of
cash flows for the six-month periods ended June 30, 2003 and 2002. These
financial statements are the responsibility of the Company's management.

     We conducted our review 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, 2002 and the related
consolidated statements of operations, shareholder's equity, and cash flows for
the year then ended, not presented herein, and in our report dated February 25,
2003, we expressed an unqualified opinion on those consolidated financial
statements and included an explanatory paragraph for a change in accounting for
goodwill. In our opinion, the information set forth in the accompanying
consolidated balance sheet as of December 31, 2002, is fairly stated, in all
material respects, in relation to the consolidated balance sheet from which it
has been derived.

     As discussed in Note B to the consolidated financial statements, effective
June 30, 2003, the Company changed its method of accounting for inventories at
certain subsidiaries.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

     Financial information for the three-month and six-month periods ended June
30, 2003 is not directly comparable to the financial information for the same
periods in 2002 primarily due to restructuring and other unusual charges in 2002
plus divestitures and an acquisition in 2002 and divestitures in 2003.
Restructuring charges of $622 thousand and $3.6 million were recorded in first
and second quarter 2002, respectively. The Company divested Castle Rubber in
second quarter 2002, and Green Bearing and St. Louis Screw in first quarter
2003. The Company purchased the assets of Ajax Magnethermic in third quarter
2002.

OVERVIEW

     The Company operates through three segments, ILS, Aluminum Products and
Manufactured Products. ILS is a leading supply chain logistics provider of
production components to large, multinational manufacturing companies, other
manufacturers and distributors. In connection with the supply of such production
components, ILS provides a variety of value-added, cost-effective supply chain
management services. The principal customers of ILS are in the semiconductor
equipment, heavy-duty truck, industrial equipment, aerospace and defense,
electrical controls, HVAC, vehicle parts and accessories, appliances, and lawn
and garden equipment industries. Aluminum Products manufactures cast aluminum
components for automotive, agricultural equipment, heavy-duty truck and
construction equipment manufacturers. 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 aerospace, automotive, steel, forging,
railroad, truck, oil, food processing and consumer appliance industries.

     The Company's sales volumes and profitability declined during 2001, due to
overall weakness in the manufacturing economy, and particularly to contraction
in the heavy-duty truck and automotive industries. Despite these sales declines,
the Company retained or gained market share in most major markets served. The
Company responded to this downturn by reducing costs, increasing prices on
targeted products, restructuring many of its businesses and selling non-core
manufacturing assets. The Company continued and extended restructuring its
businesses through 2001 and 2002, closing 20 supply chain logistics facilities,
and closing or selling eight manufacturing plants in those two years. With
regard to these actions, the Company recorded restructuring and impairment
charges of $28.5 million in 2001 and $19.2 million in 2002. Management's actions
were aimed to position the Company for increased profitability when the
manufacturing economy stabilizes and returns to growth.

     The Company's actions resulted in increased operating income in 2002
compared to 2001, despite flat sales. Operating income rose to $16.6 million in
2002, after restructuring and impairment charges of $19.2 million, compared to
an operating loss of $3.9 million in 2001, after restructuring and impairment
charges of $28.5 million and goodwill amortization of $3.7 million.

     The Company's profitability improved again in first half 2003, on
continuing flat sales. Compared to first half 2002, operating income increased
50%, or $6.6 million, to $19.8 million, on a 2% sales decline. First half 2002
operating income was negatively impacted by $4.3 million in restructuring
charges. During first half 2003, the Company continued to reduce costs and
restructure businesses, including consolidating two logistics facilities and
selling two additional non-core manufacturing businesses.

     The Company sold substantially all the assets of St. Louis Screw and Bolt
on January 29, 2003 and Green Bearing on February 21, 2003 for cash totaling
approximately $7.3 million.

     The Company sold substantially all the assets of Castle Rubber Company on
April 26, 2002 for cash of approximately $2.5 million. The Company purchased
substantially all the assets of Ajax Magnethermic Corp. on September 10, 2002
for cash of approximately $5.5 million.

     On January 1, 2002, the Company adopted Statement of Financial Accounting
Standards No. 142, "Goodwill and Other Intangible Assets" ("FAS 142"). Under FAS
142, the Company reviewed its goodwill

                                        15
<PAGE>

and other intangible assets and recorded a non-cash goodwill impairment charge
of $48.8 million, which was recorded as the cumulative effect of a change in
accounting principle effective January 1, 2002.

     Effective June 30, 2003, the Company changed its method of accounting for
the 15% of its inventories utilizing the LIFO method to the FIFO method. As
required by generally accepted accounting principles, the Company has restated
its balance sheet as of December 31, 2002 to increase inventories by the
recorded LIFO reserve ($4.4 million), increase deferred tax liabilities ($1.7
million), and increase shareholders' equity ($2.7 million). Previously reported
results of operations have not been restated because the impact of utilizing the
LIFO method had an insignificant impact on the Company's reported amounts for
consolidated net income (loss).

RESULTS OF OPERATIONS

Six Months 2003 versus Six Months 2002

     Net sales decreased by $5.7 million, or 2%, from $320.5 million for the
first six months of 2002 to $314.8 million in 2003. ILS net sales declined 5%,
or $10.9 million, of which $3.3 million related to the sale of Green Bearing and
the remainder related primarily to continued volume weakness in customer
industries. Aluminum Products net sales were 15%, or $8.5 million lower,
primarily due to the ending of $8.3 million of certain sales contracts.
Manufactured Products net sales increased 21%, or $13.7 million, primarily due
to increased sales in the induction business.

     Gross profit increased by $4.2 million, or 9%, to $50.3 million for the
first six months of 2003 from $46.1 million for the same period of 2002, and the
Company's gross margin increased to approximately 16.0% for the first six months
of 2003, from 14.4% for the same period of 2002. ILS gross margin increased,
primarily due to lower inventory costs, facility costs and other cost
reductions, partially offset by the absorption of fixed overhead over a smaller
sales base. Aluminum Products gross margin increased significantly, primarily as
a result of restructuring and cost reductions and higher margins on new
contracts. Gross margin in the Manufactured Products segment improved, primarily
as a result of increased sales and overhead efficiencies achieved in the
induction business.

     Selling, general and administrative ("SG&A") expenses increased by 6%, or
$1.8 million, to $30.5 million for the first six months of 2003 from $28.7
million for the same period in 2002. SG&A expenses increased by $3.7 million due
to the net effect of acquisitions and divestitures, partially offset by cost
reductions in the ILS and Aluminum Products segments. Consolidated SG&A expenses
as a percentage of net sales were 9.7% for the first six months of 2003 as
compared to 8.9% for the first six months of 2002, primarily due to a $.8
million reduction of net pension credits reflecting less favorable returns on
pension plan assets.

     Interest expense decreased $.1 million from $13.6 million in the first six
months of 2002 to $13.5 million in the same period of 2003, primarily due to
reduced borrowings in 2003. During the first six months of 2003, the Company
averaged outstanding borrowings of $324.2 million as compared to $333.8 million
for the corresponding period of the prior year. The $9.6 million decrease
related primarily to lower average working capital levels during the first six
months and cash from the sale of non-core manufacturing assets. The average
interest rate of 8.30% for the first half of 2003 was 13 basis points higher
than the average rate of 8.17% for the same period in 2002.

     The effective income tax rate for the six-month period ended June 30, 2003
was 15%, compared to 62% for the corresponding period in 2002. Only foreign and
certain state income taxes were provided for in 2003 because federal income
taxes were not owed due to the recognition of net operating loss carryforwards
for which valuation allowances had been provided for prior to 2003. At December
31, 2002, the Company had net operating loss carryforwards of approximately
$25.6 million. Tax benefits related to these carryforwards were fully reserved
in 2002 because the Company was in a three-year cumulative loss position.

Second Quarter 2003 versus Second Quarter 2002

     Net sales decreased by $6.7 million, or 4%, from $166.6 million in second
quarter 2002 to $159.9 million in the same quarter 2003. ILS net sales declined
7%, or $7.5 million, of which $2.1 million related to the sale
                                        16
<PAGE>

of Green Bearing and the remainder primarily to continued volume weakness in
customer industries. Aluminum Products net sales declined 20%, or $6.1 million,
due to a $4.2 million decrease relating to the ending of certain sales
contracts, and downturns in volumes on certain parts. Manufactured Products net
sales increased 21%, or $6.8 million, primarily due to increased sales in the
induction business.

     Gross profit increased by $1.5 million, or 6%, to $25.8 million for second
quarter 2003 from $24.4 million for the same quarter 2002, and the Company's
gross margin increased to approximately 16.2% for second quarter 2003, from
14.6% for the same quarter 2002. ILS gross margin increased, primarily due to
savings from restructuring and other cost reductions, partially offset by the
absorption of fixed overhead over a smaller sales base. Aluminum Products gross
margin increased significantly, primarily as a result of restructuring and cost
reductions and higher margins on new contracts. Gross margin in the Manufactured
Products segment improved, primarily as a result of increased sales and overhead
efficiencies achieved in the induction business.

     SG&A expenses increased by 6%, or $.9 million, to $15.5 million for second
quarter 2003 from $14.6 million for the same quarter 2002. SG&A expenses
increased by $2.1 million due to the net effect of acquisitions and
divestitures, partially offset by cost reductions in the ILS and Aluminum
Products segments. Consolidated SG&A expenses as a percentage of net sales were
9.7% for second quarter 2003 as compared to 8.7% for the first three months of
2002, primarily due to a $.4 million reduction of net pension credits reflecting
less favorable returns on pension plan assets.

     Interest expense decreased $.3 million from $7.0 million in second quarter
2002 to $6.7 million in the same quarter 2003 primarily due to reduced
borrowings in 2003. During second quarter 2003, the Company averaged outstanding
borrowings of $319.7 million as compared to $329.7 million for the corresponding
period of the prior year. The $10.0 million decrease related primarily to lower
average working capital levels during the quarter and cash from the sale of
non-core manufacturing assets. The average interest rate of 8.38% for the
current quarter was 6 basis points lower than the average rate of 8.44% for
second quarter 2002.

     The effective income tax rate for second quarter 2003 was 23%, compared to
47% for the corresponding period in 2002. Only foreign and certain state income
taxes were provided for in 2003 because federal income taxes were not owed due
to the recognition of net operating loss carryforwards for which valuation
allowances had been provided for prior to 2003. At December 31, 2002, the
company had net operating loss carryforwards of approximately $25.6 million. Tax
benefits related to these carryforwards were fully reserved in 2002, because the
Company was in a three-year cumulative loss position.

SEASONALITY; VARIABILITY OF OPERATING RESULTS

     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 due to holidays in the fourth quarter.

     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.
