NOTE D -- ACCOUNTING PRONOUNCEMENTS

     The Company adopted Financial Accounting Standard No. 142 "Goodwill and
Other Intangible Assets" ("FAS 142") as of January 1, 2002. The Company no
longer amortizes goodwill, but will review goodwill for impairment annually, or
more frequently if impairment indicators arise. The Company is in the process of
performing the initial impairment tests as of January 1, 2002, which must be
completed by June 30, 2002. If goodwill is determined to be impaired, the charge
would be accounted for as a cumulative effect adjustment as a result of a change
in accounting principle.

     In accordance with FAS 142, prior period amounts were not restated. A
reconciliation of the previously reported net income for the three months ended
March 31, 2001 to the amounts adjusted for the reduction of amortization
expense, net of the related income tax effect, is as follows:

     In October 2001, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets" ("FAS 144"), which supercedes FAS 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of". Although retaining many of the fundamental impairment and
measurement provisions of FAS 121, the new rules supercede the provisions of APB
Opinion 30 with regard to reporting the effects of a disposal of a segment of a
business. The adoption of this standard by the Company on January 1, 2002 did
not impact the Company's financial position, results of operations or cash
flows.

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 production components to large,

NOTE H -- RESTRUCTURING ACTIVITIES

     During 2001, the Company recorded pretax charges of $28.5 million (of which
$6.9 million related to severance and exit costs) as a result of a restructuring
plan aimed at positioning the Company for stronger profitability. The charges
consisted of asset write-downs, employee termination and severance costs related
to workforce reductions of approximately 525 employees, and other exit costs
related to the shutdown of facilities. The Company expects to substantially
complete these actions in 2002. For further details on the restructuring plan,
see Note K to the audited financial statements contained in the Company's Annual
Report on Form 10-K for the year ended December 31, 2001.

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

     As of March 31, 2002, approximately 450 of the 525 employees had been
terminated. Severance costs related to additional work force reductions of 80
employees were recorded in the first quarter of 2002. 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 Ajax Manufacturing and Castle Rubber (businesses held for
sale) were $3,642 and $3,711 for the three months ended March 31, 2002 and 2001,

                     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 March 31, 2002 and the related
consolidated statements of income and cash flows for the three-month periods
ended March 31, 2002 and 2001 and the consolidated statement of shareholders'
equity for the three-month period ended March 31, 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.

     As discussed in Note D to the consolidated financial statements, effective
January 1, 2002, the Company changed its method of accounting for goodwill.

     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, 2001 and the related
consolidated statements of income, shareholders' equity, and cash flows for the
year then ended, not presented herein, and in our report dated March 1, 2002, 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, 2001, is fairly stated, in all material respects, in
relation to the consolidated balance sheet from which it has been 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. and its subsidiaries. All significant intercompany
transactions have been eliminated in consolidation. Financial information for
the three month period ended March 31, 2002 is not directly comparable to the
financial information for the same three-month period in 2001, for several
reasons. Effective January 1, 2002, the Company no longer amortizes goodwill.
Goodwill amortization in first quarter 2001 was $955 thousand. During first
quarter 2002, the Company continued its announced restructuring activities and
recorded $622 thousand of restructuring charges. In the first quarter of 2001,
the Company expensed $950 thousand of non-recurring business-interruption costs
related to a June 2000 fire, which destroyed the Company's Cicero Flexible
Products plant. On December 21, 2001, the Company sold substantially all the
assets of Cleveland City Forge, for cash of approximately $6.1 million.

OVERVIEW

     The Company operates through three segments: Integrated Logistics Solutions
("ILS"), Aluminum Products and Manufactured Products. ILS is a leading logistics
provider of 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 services to major OEMs. The principal customers of ILS
are semiconductor equipment, technology, industrial equipment, aerospace and
defense, electrical controls, HVAC, heavy duty truck, vehicle parts and
accessories, appliances and motors 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, oil and aerospace 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 believes it has retained or gained market share in most major
markets served. The Company has responded to this economic downturn by reducing
costs, increasing prices on targeted products, restructuring businesses and
selling non-core manufacturing assets. Costs were reduced primarily by
negotiating supplier price concessions, reducing headcount through layoffs and
attrition (approximately 600 or 15% during 2001), and operating more
efficiently. Despite customer pricing pressures, the Company negotiated
significantly increased prices for several, particularly low-margin product
lines in the Aluminum Products and Manufactured Products segments. The Company
restructured many of its businesses, including planned closure of twenty
logistics warehouses and closure or sale of eight manufacturing plants. With
regard to these actions, in 2001 the Company recorded restructuring and
impairment charges of $28.5 million before tax consisting of $6.9 million for
severance and exit costs, $10.3 million recorded in cost of products sold,
primarily to write down inventory of discontinued businesses and other product
lines to fair value, and $11.3 million for the impairment of property and
equipment and other long-term assets. The Company continued to work toward the
sale of non-core manufacturing assets, including the December, 2001 sale of
substantially all the assets of Cleveland City Forge for cash of $6.1 million.

     The Company's sales volume and profitability improved in first quarter
2002. Sales increased approximately $7.2 million, or 5% compared to the fourth
quarter of 2001, and the Company returned to profitability. During first quarter
2002, the Company continued to reduce costs and restructure businesses,
including closing or consolidating three logistics warehouses and one
manufacturing plant, as previously planned.

     Management continues to implement the planned cost reduction and business
restructuring, and also continues to work toward the sale of non-core
manufacturing assets. Substantially all the assets of Castle Rubber Company were
sold after the end of the first quarter (on April 26, 2002) for cash of
approximately $2.5 million. Management's actions are intended to position the
Company for increased profitability as the manufacturing economy stabilizes and
returns to growth.

     On January 1, 2002 the Company adopted Statement of Financial Accounting
Standards No. 142 "Goodwill and Other Intangible Assets" ("FAS 142"). Under FAS
142, goodwill and intangible assets with indefinite lives are no longer
amortized, but are reviewed for impairment annually, or more frequently if
impairment indicators arise. The Company is in the process of performing the
initial impairment tests as of January 1, 2002, which must be completed by June
30, 2002. If goodwill is determined to be impaired, the charge will be accounted
for as a cumulative effect adjustment as a result of a change in accounting
principle.

RESULTS OF OPERATIONS

Three Months 2002 versus Three Months 2001

     Net sales declined by $15.6 million, or 9%, from $169.4 million in first
quarter 2001 to $153.8 million in 2002. ILS net sales declined 19%, or $22.1
million, due primarily to shrinkage in heavy truck and other customer
industries. Aluminum Products net sales increased 28%, or $5.8 million. This
increase included $2.6 million in new contracts and $3.6 million from higher
volumes and price increases in ongoing contracts, partially offset by a $.4
million decrease relating to the ending of certain sales contracts. Manufactured
Products net sales increased 2%, or $.7 million.

     Gross profit declined by $5.4 million, or 20%, to $21.7 million for first
quarter 2002, from $27.1 million for first quarter 2001, and the Company's gross
profit declined to approximately 14.1% for first quarter 2002, from 16.0% for
first quarter 2001. ILS gross margin declined primarily due to reduced volumes
resulting in the absorption of fixed operational overheads over a smaller sales
base. Aluminum Products gross margins increased significantly, due to the
absorption of fixed manufacturing overheads over a larger production base, cost
reductions and higher margins on new contracts. Gross margins in the
Manufactured Products segment decreased primarily due to pricing pressure and
the divestiture of the high-margin sales of Cleveland City Forge.

     Selling, general and administrative expenses ("SG&A") decreased by 15% or
$2.4 million, to $14.1 million for first quarter 2002 from $16.5 million for the
same period in 2001. SG&A decreased through cost reductions in all three
segments. During the first quarter of 2002, SG&A was negatively affected by a
decrease in net pension credits of $.3 million, reflecting less favorable
investment returns on pension plan assets. Consolidated SG&A expenses as a
percentage of net sales were 9.2% for the first three months of 2002 as compared
to 9.7% for the first three months of 2001. Amortization of goodwill has been
eliminated in 2002, in accordance with FAS 142.

     Interest expense decreased $1.3 million from $8.0 million in first quarter
2001 to $6.7 million in first quarter 2002 due to lower average debt outstanding
and lower average interest rates in 2002. During the first three months of 2002,
the Company averaged outstanding borrowings of $337.4 million as compared to
$355.5 million for the corresponding period of the prior year. The $18.1 million
decrease related primarily to lower working capital levels in ongoing units and
cash from the sale of Cleveland City Forge. The average interest rate of 7.92%
for the current quarter was 103 basis points lower than the average rate of
8.95% for first quarter 2001, primarily due to decreased rates on the Company's
revolving credit facility.

     The effective income tax rate for the-three month period ended March 31,
2002 was 47%, compared to 46% for the corresponding period in 2001.

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 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

                                        14

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