                    provisions of this Article IV, there is hereby created
                    a series of Cumulative Preferred Shares of the par

                         16.  The preferences, rights, restrictions or
                    qualifications and the description and terms of the
                    Cumulative Preferred Shares, 7% Series, in the respects
                    in which the shares of such series vary from shares of

                    par value, shall be as follows:

                              (i)   The annual dividend rate for such
                         series  shall be 7% per share, per annum, which
                         dividend shall be calculated, per share, at such
                         percentage multiplied by $100, payable quarterly
                         on the first days of February, May, August and
                         November in each year with respect to the
                         quarterly period ending on the day preceding each





                         such respective payment date, and the date from
                         which dividends shall be cumulative on all shares
                         of such series issued prior to the record date for
                         the dividend payable August 1, 1994 shall be the
                         date of original issue of shares of such series.

                              (ii)  Shares of such series are not
                         redeemable except as provided in clause (iv) of
                         this Division 16.

                              (iii) The preferential amounts to which the
                         holders of shares of such series shall be entitled
                         upon any voluntary or involuntary liquidation,
                         dissolution or winding up of the Corporation shall
                         be $100 per share plus an amount equal to accrued
                         and unpaid dividends.

                              (iv)(1)  A sinking fund shall be established
                         for the retirement of the shares of such series. 
                         So long as there shall remain outstanding any
                         shares of such series, the Corporation shall, to
                         the extent permitted by law, redeem as and for a
                         sinking fund requirement, out of funds legally
                         available therefor, 50,000 shares of such series,
                         at a sinking fund redemption price of $100 per
                         share plus accrued and unpaid dividends to the
                         date of redemption on August 1 of each year
                         commencing with the year 2000.  The sinking fund
                         requirements shall be cumulative so that if on any
                         such August 1 the sinking fund requirement shall
                         not have been met, then such sinking fund
                         requirement, to the extent not met, shall become
                         an additional sinking fund requirement for the
                         next succeeding August 1 on which such redemption
                         may be effected.

                                  (2)  The Corporation shall have the non-
                         cumulative option, on any sinking fund date as
                         provided in clause (iv)(1) of this Division 16, to
                         redeem at the sinking fund redemption price of
                         $100 per share plus accrued and unpaid dividends
                         to the date of redemption up to an additional
                         50,000 shares of such series.  No redemption made
                         pursuant to this clause (iv)(2) shall be deemed to
                         fulfill any sinking fund redemption established
                         pursuant to clause (iv)(1).

                                  (3)  The Corporation shall be entitled,
                         at its election, to credit against the sinking
                         fund requirement due on August 1 of any year
                         pursuant to clause (iv)(1) of this Division 16,
                         shares of such series theretofore purchased or

                                          2





                         otherwise acquired by the Corporation (other than
                         pursuant to the option provided by clause (iv)(2)
                         of this Division 16) and not previously credited
                         against any such sinking fund requirement.

                              (v)   The shares of such series shall not
                         have any rights to convert the same into and/or
                         purchase shares of any other series or class or
                         other securities, or any special rights other than
                         those specified herein.

                    FURTHER RESOLVED, that a certificate signed by the
               Chairman of the Board, the President, or a Vice President
