SECOND: The preferences, rights, voting powers, restrictions, and qualifications of the authorized preference stock are set forth in the Charter of the corporation, as restated. The following is a further description of the 6.99% Cumulative Preference Stock, 1995 Series ($100 par value), containing the preferences, restrictions, limitations as to dividends, qualifications thereof, and the times and prices of redemption thereof, as fixed by the Board of Directors and its Executive Committee: "32.(a). The 6.99% Cumulative Preference Stock, 1995 Series ($100 par value), shall entitle the holders thereof to receive, when and as declared, from the surplus or net profits of the corporation remaining after the preferential dividend requirements for the outstanding preferred stock have been provided for, yearly dividends at the rate of six and ninety-nine hundredths per cent per annum and no more, payable quarterly on the first days of January, April, July, and October in each year commencing October 1, 1995. The dividends on the 6.99% Cumulative Preference Stock, 1995 Series ($100 par value), shall be cumulative and shall be payable before any dividend on the common stock shall be paid or set apart; so that, if in any year or years dividends amounting to six and ninety-nine hundredths per cent shall not have been paid thereon, the deficiency shall be payable before any dividends shall be paid upon or set apart for the common stock. Dividends on the 6.99% Cumulative Preference Stock, 1995 Series ($100 par value), will accrue from and include September 7, 1995. (b). The 6.99% Cumulative Preference Stock, 1995 Series ($100 par value), or any portion thereof, may whenever the Board of Directors shall so determine, be redeemed by the payment to the holders thereof of the sum hereinafter specified as the redemption price at the time of redemption, in cash, for each share thereof, together with all accrued dividends.

In case less than all of the preference stock of this series at the time being outstanding is so redeemed, the shares to be redeemed shall be, as nearly as is reasonably practicable without creating fractional shares, a proportionate part of the holdings of each holder of preference stock of this series, or shall be selected, in whole or in part, by lot. At least thirty (30) days' written notice of the election of the corporation to redeem the preference stock of this series (or any part thereof, in which case the notice shall specify the particular shares to be redeemed) shall be given to each holder of the preference stock of this series so to be redeemed by mailing the same, postage prepaid, and addressed to him at his address as it appears upon the books of the corporation. When such notice shall have been so given and the funds for payment of the redemption price plus accrued dividends shall have been provided and set apart, the dividends on the shares of preference stock of this series so called for redemption and all other rights of the holders thereof, except the right to receive the redemption price plus accrued dividends, shall cease."
