        Effective November 1, 1999, National combined its former Customer Stock Purchase, and Dividend Reinvestment and Stock Purchase Plans into a new plan known as the National Fuel Direct Stock Purchase and Dividend Reinvestment Plan. The purpose of is to promote the long-term ownership of National’s common stock by allowing for the purchase thereof directly from National, through cash purchases and through reinvestment of cash dividends.

        The purpose of National’s two Tax-Deferred Savings Plans is to encourage certain employees of National and of its Subsidiaries to provide for their retirement needs by providing opportunities for long-term capital accumulation, to promote ownership of National’s common stock among certain employees, to provide an attractive employee benefit, and to keep National’s employee benefit program competitive with programs offered by other corporations.

        The purpose of National’s Retainer Policy for outside directors is to pay outside directors a portion of their annual retainer in common stock of National. This promotes the long-term ownership of National’s common stock by outside directors.

        National adopted its four award and option plans in order to attract, retain and motivate key employees of outstanding ability. These plans were intended to provide an incentive to key employees to maximize the long-range profits, revenues, and financial integrity of National by increasing the personal stake of those employees in the continued success and growth of National, and by providing significant incentives to their continuation of employment at National and its Subsidiaries.

        On June 14, 2001 the Compensation Committee of the Board of Directors of National awarded 162,600 stock options pursuant to the National Fuel Gas Company 1997 Award and Option Plan.
