Independent Auditor’s Report

To the Participants and
Plan Administrator of the
National Fuel Gas Company
Tax-Deferred Savings Plan

We have audited the accompanying statements of net assets available for plan benefits of National Fuel Gas Company Tax-Deferred Savings Plan as of December 31, 2002 and 2001, and the related statements of changes in net assets available for plan 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 of America. 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 plan benefits of National Fuel Gas Company Tax-Deferred Savings Plan as of December 31, 2002 and 2001, and the changes in net assets available for plan benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America.

Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule is presented for the purpose of additional analysis and is not a required part of the basic 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. This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

NATIONAL FUEL GAS COMPANY

TAX-DEFERRED SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS

NOTE 1 - DESCRIPTION OF PLAN

     General:

     The following is a brief description of the National Fuel Gas Company Tax-Deferred Savings Plan (the Plan) provided for general information purposes only. Participants should refer to the Plan document for more complete information. The Plan is a defined contribution plan as permitted under Section 401(k) of the Internal Revenue Code. The Plan was adopted March 21, 1989, effective as of July 1, 1989, and has been amended since that time. It is subject to the Employee Retirement Income Security Act of 1974, as amended.

     Eligibility and Participation:

     Originally, the Plan was established for the benefit of employees of National Fuel Gas Company and its subsidiaries (the Company) who were subject to a collective bargaining agreement between the Company and the International Brotherhood of Electrical Workers (IBEW), Locals 2154 and 2199 (which consolidated with 2199-J). These employees became eligible to participate in the Plan on July 1, 1989 or, if later, after completing 1,000 hours of service and attaining age 21. Employees subject to collective bargaining agreements between the Company and the IBEW Local 2279 and the Service Employee International Union (SEIU) F & O Conference - Local 22 (prior to their consolidation on September 1, 1999, the International Brotherhood of Firemen and Oilers, Locals 22, 23, 25 and 251) also became eligible to participate in the Plan on August 1, 1990 or, if later, after completing 1,000 hours of service and attaining age 21.

     Contributions:

     Plan participants may direct the Company to reduce their base pay by a specified full percentage of at least 2% and not more than 50% as amended by the Plan during the year. These wage reductions are subject to certain Plan and Internal Revenue Code limitations, and the Company remits them to the Plan Trustee on the participants’ behalf. In addition, the Company makes an employer matching contribution that ranges from 1% to 3.5% of the participants’ base pay depending upon their years of service and rate of wage reduction contributions. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. Participants direct the investment of their contributions into various investment options offered by the Plan. Participants may change their investment allocation on a daily basis.

     “Base pay” is defined in the Plan as a participant’s basic compensation for a payroll period. An individual participant’s wage reduction contributions to the Plan are subject to ceilings imposed by the Internal Revenue Service. However, Company matching contributions are not subject to such ceilings. The ceiling is $11,000 for 2002 and $12,000 for 2003. If a participant is age 50 or over, the ceiling increases to $12,000 for 2002 and $14,000 for 2003.

     Participants’ accounts, including all wage reduction contributions, employer matching contributions, and the earnings thereon, are at all times fully vested and nonforfeitable.

     Employer Matching Contributions:

     Employer matching contributions are invested in a fund consisting primarily of the common stock of National Fuel Gas Company (National Stock Fund B). This fund also maintains a small cash position in Vanguard Prime Money Market Fund and may also include receivables and/or payables for unsettled security transactions and receivables for accrued dividends. A separate account is maintained for each participant showing his/her interest in this fund. Participants may not redirect their interests in this fund into any other fund.

     Withdrawals, Loans and Distributions:

     Plan participants (or their beneficiaries) may receive distributions from the Plan upon death, retirement, disability or other termination, in accordance with a qualified domestic relations order, or in the event of hardship, subject to the Plan’s limitations and restrictions. Additionally, Plan participants may borrow from their accounts in accordance with various Plan rules. In certain cases, participants may postpone receipt of Plan distributions.

     Participant Accounts:

     Each participant’s account is credited with the participant’s contribution and an allocation of (a) the Company’s contribution and, (b) Plan earnings, and charged with an allocation of investment fees. 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.

      Administration:

     National Fuel Gas Company is the Administrator of the Plan. A Tax-Deferred Savings Plan Committee appointed by National Fuel Gas Company’s Board of Directors exercises National Fuel Gas Company’s duties as Administrator. The assets of the Plan are held by the Trustee, Vanguard Fiduciary Trust Company (Vanguard).

     Although it has not expressed any intent to do so, National Fuel Gas Company has the right to terminate, amend, or modify the Plan at any time subject to the provisions of ERISA.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of Accounting and Valuation:

     The accounts of the Plan are maintained on the accrual basis. National Stock Funds A (participant directed) and B (non-participant directed) are reported on a current value basis using the quoted market value of National Fuel Gas Company common stock and the value of the cash positions and receivables at the close of the Plan year. Shareholders of National Fuel Gas Company stock have the right to give voting instructions to the Trustee with respect to the number of shares of common stock of National Fuel Gas Company that are held on their behalf. Mutual funds are reported on a current value basis, using quoted market values of the investments at the close of the Plan year. The investment contracts in the Vanguard Retirement Savings Trust are carried at the stated unit values of the funds which are derived from the fair value of the underlying investments. National Fuel Gas Company stock distributed to participants is reflected at market value at the date of distribution. Purchases and sales of investments are recorded on a trade-date basis. Interest income is accrued when earned. Dividend income is recorded on the ex-dividend date. Capital gain distributions are included in investment income.

     A two-for-one stock split of National Fuel Gas Company stock occurred on September 7, 2001. The record date for the stock split was August 24, 2001. All share amounts have been adjusted to reflect the two-for-one stock split.

     The market volatility of equity-based investments is expected to substantially impact the value of such investments at any given time. It is possible that the value of the Plan’s investments both in total and in individual participant accounts, has changed since December 31, 2002.

     Use of Estimates:

     The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of additions and deductions during the reporting period. Actual results could differ from those estimates.

     Administrative Expenses:

     Expenses related to administration of the Plan and Trust are borne by the Company. The Company paid Vanguard $48,803 and $50,964, for services in connection with the Plan and Trust for the years ended December 31, 2002 and December 31, 2001, respectively. Brokerage commissions and similar costs of acquiring or selling securities (if any) that are incurred by the investment funds are borne by the participant. Loan origination fees and annual maintenance fees for each loan are also borne by the participant.

NOTE 3 - INCOME TAXES

     The Internal Revenue Service has determined in a letter dated September 9, 2002 that the Plan qualifies under Section 401(a) and Section 401(k) of the Internal Revenue Code of 1986, as amended. Accordingly, no provision for income taxes has been recorded. Although the Plan has been amended since receiving the determination letter, the Plan administrator and the Plan’s tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the Internal Revenue Code.

NOTE 4 - PARTIES-IN-INTEREST

     The Plan invests in shares of mutual funds managed by an affiliate of Vanguard Fiduciary Trust Company (VFTC). VFTC acts as trustee for only those investments as defined by the Plan. The Plan also invests in common stock of National Fuel Gas Company. Transactions in such investments qualify as party-in-interest transactions which are exempt from the prohibited transaction rules. Investment income (loss) from parties-in-interest amounted to $2,701,343 and $2,594,299 for the years ended December 31, 2002 and December 31, 2001, respectively.

NOTE 5 – INVESTMENTS

NOTE 6 – SUBSEQUENT EVENT

     The Board of Directors of the Company has approved the merger of the National Fuel Gas Company Employees’ Thrift Plan (the “Thrift Plan”) into the Plan, in part, and into another plan, in part. Specifically, the account balances contained in the Thrift Plan’s Government Bond Fund and the Pooled Investment Contract Fund will be merged into the Plan. The account balances containing the employer directed investment fund of the Thrift Plan, which consisted of National Fuel Gas Company Common Stock, will be merged into another plan. The merger will be effective as of August 1, 2003. Funds previously invested in the Government Bond Fund will initially be invested in the Vanguard Total Bond Market Index Fund, and funds previously invested in the Pooled Investment Contract Fund will initially be invested in the Vanguard Retirement Savings Trust. Former Thrift Plan participants will have the option to move these funds into other investment options offered by the Plan and will retain the same rights and features of the former Thrift Plan. Former Thrift Plan funds will be kept separate from any funds that a participant invests directly into the Plan.
