                   Notes to Financial Statements (Unaudited)

                         December 31, 2002 and 2001 and
                          Year Ended December 31, 2002

A. DESCRIPTION OF THE PLAN

The following description of the Sinterloy Corporation 401(k) Plan (the "Plan")
provides only general information. Participants should refer to the summary plan
description for a more complete description of the Plan's provisions.

GENERAL

The Plan was established January 1, 1995 as a defined contribution plan covering
all non-union employees of Sinterloy Corporation (the Company and Plan Sponsor)
who have completed one year of service, as defined. The Company is a wholly
owned subsidiary of Hawk Corporation. The Plan is subject to the provisions of
the Employee Retirement Income Security Act of 1974 (ERISA).

CONTRIBUTIONS

Participants may elect to contribute not less than 1% nor more than 10% of their
pretax compensation to the Plan subject to maximum limitations set by the
Internal Revenue Code. The Plan Sponsor makes a matching contribution equal to
50% of the participant's contribution up to 10% of the participant's
compensation. The Plan Sponsor also provides that the Plan Sponsor make
additional discretionary contributions. The Plan Sponsor did not make a
discretionary contribution for the 2002 Plan year. Forfeited balances are
allocated back to participant's accounts under the same manner as the
discretionary contributions. At December 31, 2002, there were no forfeitures
available to allocate to participants.

PARTICIPANT ACCOUNTS

Each participant's account is credited with the participant's contributions and
allocations of (a) the Plan Sponsor's contributions and (b) Plan earnings.
Allocations are based on participant earnings or account balances, as defined.
The benefit to which a participant is entitled is the benefit that can be
provided from the participant's account.

           Notes to Financial Statements--Continued


A. DESCRIPTION OF THE PLAN - CONTINUED

VESTING AND DISTRIBUTIONS

Participants are immediately vested in their contributions. Prior to January 1,
1999, participants were 100% vested in Plan Sponsor matching contributions.
Beginning January 1, 1999, vesting of Plan Sponsor discretionary and matching
contributions is based upon years of continuous service. A participant is 100%
vested after six years of credited service based on a graded vesting schedule.
Distributions from a participant's account are limited to termination of
employment, death, retirement or proven hardship.

INVESTMENT OPTIONS

The Plan's funds are primarily held in a group annuity contract issued by
Connecticut Plan Sponsor and employee contributions in any of several investment
options, including the Hawk Corporation common stock.

PARTICIPANT LOANS

Participants may borrow from their fund accounts up to the lesser of $50,000 or
50% of their vested balance. Loan terms range from 1 to 5 years. The terms of
such a loan are determined by the Company based on maturity dates quoted by
commercial banks for a similar loan. The loans are secured by the balance in the
participant's account and bear interest at a rate commensurate with local
prevailing rates at the time of application. Principal and interest is paid
through monthly payroll deductions.

PAYMENT OF BENEFITS

In the case of normal retirement, death, permanent disability or termination
prior to retirement, a participant may elect to receive the payout of his or her
vested account balance in the form of installments, an annuity or lump sum.

EXPENSES

The Plan Sponsor pays substantially all costs of Plan administration.

B. SUMMARY OF ACCOUNTING POLICIES

INVESTMENT VALUATION

Investments in the Guaranteed Income Fund are stated at contract value as
determined by CIGNA, which approximates fair value. CIGNA has the right to defer
certain disbursements (excluding retirement, termination, and death or
disability disbursements) or transfers from the Guaranteed Income Fund when
total amounts disbursed from the pool in a given calendar year exceed 10% of the
total assets in that pool on January 1 of that year.

All other investments are stated at fair value as determined by the Trustee, on
the last business day of the Plan year. Participant loans are valued at the
outstanding balance, which approximates fair value.

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

C. INVESTMENTS

During 2002, the Plan's investments (including investments purchased, sold, as
well as held, during the year) depreciated in fair value as follows:




                                                                            NET REALIZED
                                                                           AND UNREALIZED
                                                                            DEPRECIATION

                                                                           OF INVESTMENTS

                                                                           =============

D. PLAN TERMINATION

Although it has not expressed any intent to do so, the Plan Sponsor has the
right under the Plan to discontinue its contributions at any time and to
terminate the Plan subject to the provisions of ERISA. In the event of Plan
termination, participants will become 100% vested in their accounts.

E. INCOME TAX STATUS

The Plan has received an opinion letter from the Internal Revenue Service dated
February 6, 2002, stating that the written form of the underlying prototype plan
document is qualified under Section 401 (a) of the Internal Revenue Code (the
Code), and that any employer adopting this form of a plan will be considered to
have a plan qualified under Section 401 (a) of the Code. Therefore, the related
trust is exempt from taxation. Once qualified, the Plan is required to operate
in conformity with the Code to maintain its qualification. The plan
administrator believes the Plan is being operated in compliance with the
applicable requirements of the Code and, therefore, believes that the Plan is
qualified and the related trust is tax exempt.
