REPORT OF INDEPENDENT AUDITORS To the Westinghouse Air Brake Technologies Corporation Savings Plan for Hourly Employees and Participants: We have audited the accompanying statements of net assets available for benefits of the Westinghouse Air Brake Technologies Corporation Savings Plan for Hourly Employees as of December 31, 2002 and 2001 and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant 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 net assets available for benefits of the Plan as of December 31, 2002 and 2001, and the changes in its net assets available for benefits for the years then ended, in conformity with accounting principles generally accepted in the United States. Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31,2002 is presented for purposes of additional analysis and is not a required part of the financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule is the responsibility of Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole. /s/ Ernst & Young LLP June 6, 2003 1

WESTINGHOUSE AIR BRAKE TECHNOLOGIES CORPORATION SAVINGS PLAN FOR HOURLY EMPLOYEES NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2002 AND 2001 1. DESCRIPTION OF PLAN: The following brief description of the Plan is provided for general information purposes only. Participants should refer to the plan document and/or summary plan description for more complete information. General The Westinghouse Air Brake Technologies Corporation Savings Plan for Hourly Employees (the Plan), effective May 1, 1999, is a contributory plan intended to comply with the provisions of Sections 401(a), 401(k), and 401(m) of the Internal Revenue Code (IRC). Contributions Participants may contribute, through payroll deductions, employee elective contributions from 1% to 20% of their compensation, limited to $11,000 in 2002. In addition, participants may contribute employee after-tax contributions from 1% to 20% of their compensation in 2002. Employee contributions were limited to contributing up to 16% of their compensation in 2001. Participant total annual contributions may not exceed the contribution limits under Section 415(c) of the IRC. In addition, the combination of an employee's elective contribution and after-tax contribution could not exceed 20% and 16% of his/her compensation in 2002 and 2001, respectively. Withdrawals Participants may make the following types of withdrawals: In-Service Withdrawals--A participant may withdraw any portion of his/her employee after-tax account and rollover accounts once in any six-month period. Once a participant has reached age 59-1/2, he/she can withdraw any portion of his/her employee elective account, provided that the participant simultaneously withdraws (or has previously withdrawn) the entire amount of his/her employee after-tax account and rollover accounts, if applicable. Hardship Withdrawals--In the case of hardship, as defined in the plan document, the participant can receive 100% of his/her employee elective account. Hardship withdrawals are limited to once every plan year. Loans Participants may receive loans from the Plan. At no time shall the loans of the participant exceed the lesser of 50% of the value of the participant's vested balance of his/her account, reduced by any outstanding loan balance or $50,000. The loans bear interest based on prevailing commercial rates as determined quarterly by the plan administrator. The interest rates on participant loans range from 7.0% to 10.5%. Vesting Employee contributions are at all times 100% vested and nonforfeitable. 4

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Basis of Accounting The accounts of the Plan are maintained on the accrual basis of accounting. Expenses incurred by the plan administrator, investment manager and trustee for their services and costs in administering the Plan are paid directly by the Westinghouse Air Brake Technologies Corporation (the Company). Investments Investments are valued at their market values based on published quotations. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires the plan administrator to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from these estimates. 3. INVESTMENTS: The trustee of the Plan holds the Plan's investments and executed transactions therein. The fair market values of individual assets that represent 5% or more of the Plan's net assets as of December 31, 2002 and 2001 are as follows: December 31 2002 2001 ---- ----- Fidelity Managed Income Portfolio II $336,071 $379,273 T. Rowe Price Science & Technology Fund 68,134 150,123 Fidelity Asset Manager Fund 62,015 60,656 Fidelity Freedom 2040 Fund 49,246 93,280 Fidelity Equity Income Fund 46,111 63,520 For the years ended December 31, 2002 and 2001 investment income for the Plan is as follows: Years ended December 31, 2002 2001 ---- ---- Net appreciation (depreciation) in fair value of investments: Corporate common stock $ 4,323 $ 4,148 Mutual funds (113,374) (142,867) --------- --------- (109,051) (138,719) Interest & dividends 27,836 37,264 --------- --------- Total investment loss $ (81,215) $(101,455) ========= ========= Investment Options The trustee of the investments is Fidelity Management Trust Company (Fidelity) per the Trust Agreement dated May 1, 1999. Fidelity maintains the investments and provides record-keeping functions for the Plan. Each participant's account, at the discretion of the participant, may be invested in a variety of funds. 4. PLAN TERMINATION: In the event the Plan is terminated, the Company will direct either (a) that the investment manager and trustee continue to hold the participants' accounts in accordance with the Plan, or (b) that the investment manager and trustee immediately distribute to each participant all amounts in the participant's account in a single lump-sum payment. 5

5. TAX STATUS The Plan has received a determination letter from the Internal Revenue Service dated November 19, 2002, stating that the Plan is qualified under Section 410(a) of the Internal Revenue Code (the Code) and, 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 has indicated that it will take the necessary steps, if any, to maintain the Plan's qualified status. 6. SUBSEQUENT EVENT Effective January 1, 2003, Service Center hourly employees, who were participants in the Plan, were transferred into the Westinghouse Air Brake Technologies Corporation Savings Plan (Savings Plan). Assets of $496,490, representing these participants' accounts, were transferred into the Savings Plan from the Plan. 6
