If the assets of the Corporation are not sufficient to pay such amounts in full, holders of all shares of Preferred Stock will participate in the distribution of assets ratably in proportion to the full amounts to which they are entitled or in such order or priority, if any, as will have been fixed in the resolution or resolutions providing for the issue of the series of Preferred Stock.

The par value of the Series A Junior Preferred Stock shall be $.01 per share. 2. Accrual and Payment of Dividends a. The holders of Series A Junior Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors out of funds of the Corporation legally available therefor, cumulative cash dividends at the rate of $12 per share per annum. Such dividends shall be payable in annual installments in arrears commencing April 1, 2001 and thereafter on the first day of April (unless such day is not a business day in which event on the last preceding business day) in each such year (hereinafter referred to as a "Dividend Accrual Date"), except that the dividend payment payable on April 1, 2001 shall be calculated from the date of original issuance through April 1, 2001. Each such dividend on Series A Junior Preferred Stock when paid shall be payable to holders of record as they appear on the stock books of the Corporation on the date established by the Board of Directors of the Corporation as the record date for the payment of such dividend (which record date shall not precede the date upon which the resolution fixing such record date is adopted and which record date shall be not more than sixty days prior to such action). If no record date is fixed, the record date for determining holders for such purpose shall be at the close of business on the date on which the Board of Directors adopts the resolution relating to such dividend payment. Dividends with respect to any shares of Series A Junior Preferred Stock shall accrue (whether or not earned or declared) from the date of issue of such shares. b. Such dividends on the Series A Junior Preferred Stock shall be cumulative, whether or not earned or declared, so that if at any time full cumulative dividends at the rate aforesaid on all shares of Series A Junior Preferred Stock then outstanding to the end of the annual dividend period next preceding such time shall not have been paid, the amount of the deficiency shall be paid before any sum shall be set aside for or applied by the Corporation -6- to the purchase, redemption or other acquisition for value of any shares of Junior Stock (either pursuant to any applicable sinking fund requirement or otherwise) or any dividend or other distribution shall be paid or declared and set apart for payment on any Junior Stock (other than a dividend payable in Junior Stock); provided, however, that the foregoing shall not prohibit the Corporation from repurchasing shares of Junior Stock from a former employee of the Corporation (or a subsidiary of the Corporation) where such repurchase arises from the Corporation's option to repurchase such shares upon termination of such employee's employment with the Corporation (or a subsidiary) pursuant to a written agreement between the Corporation and such employee. Accrued dividends on the Series A Junior Preferred Stock if not paid on the first or any subsequent Dividend Accrual Date following accrual shall thereafter accrue additional dividends in respect thereof (the "Additional Dividends"), compounded annually, at the rate of 12% per annum. c. When dividends are not paid in full upon the Series A Junior Preferred Stock and any other stock ranking on a parity as to dividends with the Series A Junior Preferred Stock, all dividends paid upon shares of Series A Junior Preferred Stock and any other stock ranking on a parity as to dividends with the Series A Junior Preferred Stock shall be paid pro rata so that in all cases the amount of dividends paid per share on the Series A Junior Preferred Stock and such other stock shall bear the same ratio that accrued dividends per share on the shares of Series A Junior Preferred Stock and such other stock bear to each other. Except as provided in the preceding sentence, unless full cumulative dividends on the Series A Junior Preferred Stock have been paid, no dividends shall be declared or paid or set aside for payment upon any other stock of the Corporation ranking on a parity with the Series A Junior Preferred Stock as to dividends. d. An annual dividend period shall commence on the day following a Dividend Accrual Date and shall end on the next succeeding Dividend Accrual Date. 3. Preference on Liquidation a.

If upon any liquidation, dissolution or winding up of the Corporation, the net assets of the Corporation shall be insufficient to pay the holders of all outstanding shares of Series A Junior Preferred Stock and of any shares of stock ranking on a parity with the Series A Junior Preferred Stock the full amounts to which they respectively shall be entitled, such assets, or the proceeds thereof, shall be distributed ratably among the holders of the Series A Junior Preferred Stock and of any shares of stock ranking on a parity with the Series A Junior Preferred Stock. Holders of Series A Junior Preferred Stock shall not be entitled, upon the liquidation, dissolution or winding up of the Corporation, to receive any amounts with respect to such stock other than the amounts referred to in this Article IV.B(3)(a). b. Neither the purchase nor redemption by the Corporation of shares of any class of stock in any manner permitted by the Certificate of Incorporation or any amendment thereof, nor the merger or consolidation of the Corporation with or into any other corporation or corporations, nor a sale, transfer or lease of all or substantially all of the Corporation's assets shall be deemed to be a liquidation, dissolution or winding up of the Corporation for the purposes of this Article IV.B(3); provided, however, that any consolidation or merger of the Corporation in which the Corporation is not the surviving entity shall be deemed to be a liquidation, dissolution or winding up of the affairs of the Corporation within the meaning of this Article IV.B(3) if, (A) in connection therewith, the holders of Common Stock of the Corporation receive as consideration, whether in whole or in part, for such Common Stock (1) cash, (2) notes, debentures or other evidences of indebtedness or obligations to pay cash or (3) preferred stock of the surviving entity (whether or not the surviving entity is the Corporation) which ranks on a parity with or senior to the preferred stock received by holders of the Series A Junior Preferred Stock with respect to liquidation or dividends or (B) the holders of the Series A Junior Preferred Stock do not receive preferred stock of the surviving entity with rights, powers and preferences equal to (or more favorable to the holders than) the rights, powers and preferences of the Series A Junior Preferred Stock. -8- 4.
