RATIOS OF EARNINGS TO FIXED CHARGES

        The following table sets forth our unaudited ratios of earnings to fixed charges for each of the years 1997 through 2001.

  1997
  1998

  2000
  2001
Ratio of earnings to fixed charges (1)   4.02x   3.84x   3.77x   3.81x   3.75x

(1)
For the purpose of computing the ratio of earnings to fixed charges, earnings have been calculated by adding to income before interest expense, current and deferred federal and state income taxes, investment tax credits deferred and restored charged (credited) to operations and the estimated interest component of rentals. Fixed charges represent interest expense, amortization of debt discount, premium and expense, and the estimated interest component of rentals.


SUPPLEMENTAL PLAN OF DISTRIBUTION

        We are offering the notes on a continuous basis to or through our agent, Banc One Capital Markets, Inc., and such other agent or agents as we may appoint from time to time and identify in the applicable pricing supplement.

        Our agent may purchase the notes, as principal, for resale to investors and other purchasers at varying prices relating to prevailing market prices at the time of resale. The prices will be determined by the agent, or, if so agreed, at a fixed public offering price. Unless otherwise specified in the applicable pricing supplement, any note sold to the agent as principal will be purchased by the agent at a price equal to 100% of the principal amount of the note less a percentage equal to the commission applicable to an agency sale of a note having an identical stated maturity, as described below. The agent may sell notes it has purchased from us as principal to other dealers for resale to investors and may allow any portion of the discount received in connection with purchases from us to the dealers. After the initial public offering of notes, the public offering price, in the case of notes to be resold at a fixed public offering price, any concession and the discount may be changed.

        In connection with the offering, the agent, when acting as principal, and its affiliates may purchase and sell notes in the open market. These transactions may include over-allotment, short covering transactions and stabilizing transactions. Over-allotment involves sales of notes in excess of the principal amount of notes to be purchased by the agent in the offering, which creates a short position. Short covering transactions involve purchases of notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions consist of certain bids or purchases of notes made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress.

        Any of these activities may have the effect of preventing or retarding a decline in the market price of the notes. They may also cause the price of the notes to be higher than the price that would otherwise exist in the open market in the absence of such transactions. The agent may conduct these transactions in the over-the-counter market or otherwise. If the agent commences any of these transactions, it may discontinue them at any time.

        We may also sell notes through the agent, on an agency basis, using its best efforts to solicit offers to purchase the notes at a price equal to 100% of the principal amount of the notes, unless otherwise specified in the applicable pricing supplement. We will pay to the agent a commission ranging from .125% to .750% of the principal amount of each note, depending upon its stated maturity, sold through the agent. We will have the sole right to accept offers to purchase notes, and we may reject any such offer in whole or in part. The agent will have the right, in its discretion reasonably exercised, to reject in whole or in part any offer to purchase notes received by it.

S-2



        We reserve the right to sell notes directly to investors on our own behalf in the jurisdictions where we are authorized to do so or as otherwise provided in the applicable pricing supplement. In those circumstances, we will have the sole right to accept or reject any offer to purchase notes in whole or in part. In the case of sales made directly to investors without the assistance of the agent, we will not pay any sales commissions.

        We estimate that we will incur approximately $200,000 in expenses in connection with this program.

        An agent may be deemed to be an "underwriter" within the meaning of the Securities Act of 1933, as amended. We have agreed to indemnify the agent against certain liabilities, including liabilities under the Securities Act, or to contribute to payments which the agent may be required to make in respect of such liabilities. We have also agreed to reimburse the agent for certain of its expenses, including, but not limited to, the fees and expenses of counsel to the agent.

        We have been advised by the agent that it may from time to time purchase and sell notes in the secondary market, but that it is not obligated to do so. We cannot assure you that there will be a secondary market for the notes or that there will be liquidity in such market, if one develops. From time to time, the agent may make a market in the notes.

        In the ordinary course of our business, the agent and its affiliates may engage in transactions with and perform services for us.
