|   | H.     The      Corporation through its Board of Directors and conformable with Sections      512 and 513 of the Business Corporation Law of New York, may from time to      time redeem the whole or any part of the Second Series Preferred Stock at      the market price of the number of shares of common stock into which such      number of preferred shares would have been convertible as aforesaid with      respect to the conversion of such shares, plus any arrearages thereon that      may be due and unpaid. The notice of such redemption shall be mailed not      less than fifteen (15) days prior to the date upon which the stock is to      be redeemed to each holder of stock so to be redeemed, at such holder’s      address as it appears on the books of the Corporation. In the event that      less than all of the outstanding preferred stock of the Corporation is to      be redeemed, the amount to be redeemed and the method of effecting such      redemption, whether by lot or pro rata or otherwise, may be determined by      the Board of Directors. On and after the date fixed for such redemption,      the holders of shares so called for redemption shall cease to be entitled      to any further dividends, and the respective holders thereof shall have no      right or interest thereon or therein, by reason of the ownership of such      shares; except to receive the said redemption price, as a debt without      interest, upon presentation and surrender of their certificates      therefor. |   |
