         Holders of Shares shall be entitled to receive, when, as and if
declared by the Board of Directors out of funds of the Company legally available
therefor, cumulative cash dividends at the rate of 7.14 % of the liquidation
preference per Share (equivalent to $7.14 per annum per Share). Such dividends
shall accrue and be cumulative from the date of original issue and shall be
payable quarterly in arrears on the last day of each March, June, September and

(each, a "Dividend Payment Date"). The first dividend on the Shares, if
declared, will be paid on March 31, 1998. Any dividend payable on the Shares for
any partial dividend period will be computed on the basis of a 360-day year
consisting of twelve 30-day months. Dividends will be payable to holders of
record as they appear in the records of the Company at the close of business on
the applicable record date, which shall be the 15th day of the calender month in
which the applicable Dividend Payment Date falls or on such other date
designated by the Board of Directors of the Company for the payment of dividends
that is not more than 30 nor less than 10 days prior to such Dividend Payment
Date.

         The Shares will, with respect to dividend rights and rights upon
liquidation, dissolution or winding up of the affairs of the Company, rank (i)
senior to all classes or series of common stock of the Company, and to all
equity securities ranking junior to the Shares with respect to dividend rights
or rights upon liquidation, dissolution or winding up of the affairs of the
Company, (ii) on a parity with all equity securities issued by the Company the
terms of which specifically provide that such equity securities rank on a parity
with the Shares with respect to dividend rights or rights upon liquidation,
dissolution or winding up of the affairs of the Company, and (iii) junior to all
equity securities issued by the Company the terms of which specifically provide
that such equity securities rank senior to the Shares with respect to dividend
rights or rights upon liquidation, dissolution or winding up of the affairs of
the Company.

         The Shares have no stated maturity and will not be subject to any
sinking fund or mandatory redemption. The Shares shall be redeemable as provided
in the Designation.
