Except with the consent of the holders of a majority of the shares of the Preferred Stock at the time outstanding, given in writing or by vote at a meeting duly called and held for the purpose, the corporation shall not issue, sell or otherwise dispose of authorized but unissued shares of the Preferred Stock (except at a time when no shares of Preferred Stock are outstanding) or any other stock ranking on a parity with the Preferred Stock in respect of dividends or payment in case of liquidation, dissolution or winding up of the corporation, or reissue, sell or otherwise dispose of any reacquired shares of the Preferred Stock or such other stock, other than (a) to refinance an equal par value or stated value of the Preferred Stock or of stock at the time outstandinq ranking prior to or on a parity with the Preferred Stock in respect of dividends or payment in case of liquidation, dissolution or winding up of the corporation or (b) Preferred Stock issued as dividends on outstanding shares of Preferred Stock the terms of which expressly permit or require the corporation to pay such dividends in additional shares of Preferred Stock, at any time prior to May 16, 1992, nor at any time thereafter: 1. unless, for a period of 12 consecutive calendar months within the 15 conseCutive calendar months immediately preceding the calendar month in which any such shares shall be issued (but in no event including any month prior to May 16, 1391), the Income before Interest Charges of the corporation for said 12-month period available for the payment of interest, determined in accordance with the systems of accounts then prescribed for the corporation by the State of New Hampshire Public Utilities Commission (or by such other official body as may then have authority to prescribe such systems of accounts), but in any event after deducting taxes including taxes based on income and the amount charged by the corporation on its books to depreciation expense, (including, in any case in which such stock is to be issued, sold or otherwise disposed of in connection with the acquisition of any property (including property directly or indirectly acquired or disposed of by the corporation, whether consisting of stock or other ownership interests, partnership participation or otherwise), the Income before Interest Charges of the property to be so acquired, computed as nearly as practicable in the manner specified above) is at least one and one-half (1 1/2) times the sum of (a) the interest charges for one year on all indebtedness which shall then be outstanding (includinq any indebtedness proposed to be created in connection with the issue, sale or other disposition of such shares, but not including any indebtedness proposed to be retired in connection with such issue, sale or other disposition or indebtedness held by or for the account of the corporation), calculated, in the case of floating rate indebtedness, as if the rate in effect on the date of the computation is the applicable rate for the entire period, and (b) such annual rental charges as shall not be deducted in such determination of Income before Interest Charges and (c) an amount equal to all annual dividend requirements on all outstanding shares of the Preferred Stock and all other stock, if any, ranking on a parity with or having priority over the Preferred Stock as to dividends or payments in case of liquidation, dissolution or winding up of the corporation, including the shares proposed to be issued, but not including any shares proposed to be retired in connection with such issue, sale or other disposition; or 2. if such issue, sale or disposition would bring the aggregate of the amount payable in connection with an involuntary liquidation of the corporation with respect to all shares of the Preferred Stock and all shares of stock, if any, ranking on a parity with or having priority over the Preferred Stock as to dividends or payments in case of liquidation, dissolution or winding up of the corporation to an amount in excess of the sum of the junior stock equity. If for the purposes of meeting the requirements of this clause 2, it shall have been necessary to take into consideration any earned surplus of the corporation, the corporation shall not thereafter pay any dividends on or make any distributions in respect of, or make any payment for the purchase or other acquisition of, junior stock which would result in reducing the junior stock equity to an amount less than the amount payable on involuntary liquidation of the corporation with respect to the Preferred Stock and all shares ranking on a parity with or having a priority over the Preferred Stock in respect of dividends or payments in case of liquidation, dissolution or winding up of the corporation at the time outstanding. If during the period for which Income before Interest Charges is to be determined for the purpose set forth in this subdivision 6C the amount, if any, required to be expended by the corporation during such period for property additions pursuant to a renewal and replacement fund or similar fund established under any indenture of mortgage or deed of trust of the corporation shall exceed the amount deducted during such period in the determination of such Income before Interest Charges on account of depreciation and amortization of electric plant acquisition adjustments (including for this purpose any amount deducted on account of the acquisition premium referred to in subdivision 2E of this Article V), such excess shall also be deducted in determining such Income before Interest Charges. 6D.
