          RESOLVED, that pursuant to the authority vested in the Board of
          Directors of this Corporation in accordance with the provisions of
          the Certificate of Incorporation, a series of Preferred Stock, par
          value $4.00 per share, of the Corporation be and hereby is created,
          and that the designation and number of shares thereof and the voting
          and other powers, preferences and relative, participating, optional
          or other rights of the shares of such series and the qualifications,
          limitations and restrictions thereof are as follows:

     SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

     Section 1.     Designation, Par Value and Amount. The shares of such
series shall be designated as "Series A Preferred Stock" (hereinafter referred
to as "Series A Preferred Stock"), the shares of such series shall be with par
value of $4.00 per share, and the number of shares constituting such series
shall be 200,000.

     Section 2.     Dividends and Distributions.

     (A)  Subject to the prior and superior rights of the holders of any
shares of any series of Preferred Stock ranking prior and superior to the
shares of Series A Preferred Stock with respect to dividends, the holders of
shares of Series A Preferred Stock shall be entitled to receive, when, as and
if declared by the Board of Directors out of assets legally available for the
purpose, quarterly dividends payable in cash on the first business day of
March, June, September and




December in each year (each such date being referred to herein as a "Quarterly
                                                                    ----------
Dividend Payment Date"), commencing on the first Quarterly Dividend Payment
- ----------------------
Date after the first issuance of a share or fraction of a share of Series A
Preferred Stock, in an amount per share (rounded to the nearest cent) equal to
the greater of (a) $1.00 or (b) subject to the provision for adjustment
hereinafter set forth, 5000 (subject to adjustment) times the aggregate per
share amount of all cash dividends, and 5000 (subject to adjustment) times the
aggregate per share amount (payable in kind) of all non-cash dividends or other
distributions other than a dividend payable in shares of Common Stock, par
value $.40 per share, of the Corporation (the "Common Stock") or a subdivision
                                               ------------
of the outstanding shares of Common Stock (by reclassification or otherwise),
declared on the Common Stock since the immediately preceding Quarterly Dividend
Payment Date, or, with respect to the first Quarterly Dividend Payment Date,
since the first issuance of any share or fraction of a share of Series A
Preferred Stock.

     (B)  The Corporation shall declare a dividend or distribution on the
Series A Preferred Stock as provided in paragraph (A) above immediately after
it declares a dividend or distribution on the Common Stock (other than a
dividend payable in shares of Common Stock); provided that, in the event no
dividend or distribution shall have been declared on the Common Stock during
the period between any Quarterly Dividend Payment Date and the next subsequent
Quarterly Dividend Payment Date, a dividend of $1.00 per share on the Series A
Preferred Stock shall nevertheless be payable on such subsequent Quarterly
Dividend Payment Date.

     (C)  Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Preferred Stock from the Quarterly Dividend Payment Date
next preceding the date of issue of such shares of Series A Preferred Stock,
unless the date of issue of such shares is prior to the record date for the
first Quarterly Dividend Payment Date, in which case dividends on such shares
shall begin to accrue from the date of issue of such shares, or unless the date
of issue is a Quarterly Dividend Payment Date or is a date after the record
date for the determination of holders of shares of Series A Preferred Stock
entitled to receive a quarterly dividend and before such Quarterly Dividend
Payment Date, in either of which events such dividends shall begin to accrue
and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid
dividends shall not bear interest. Dividends paid on the shares of Series A
Preferred Stock in an amount less than the total amount of such dividends at
the time accrued and payable on such shares shall be allocated pro rata on a
share-by-share basis among all such shares at the time outstanding. The Board
of Directors may fix a record date for the determination of holders of shares
of Series A Preferred Stock entitled to receive payment of a dividend or
distribution declared thereon, which record date shall be not more than days
prior to the date fixed for the payment thereof.

     Section 3.     Voting Rights. The holders of shares of Series A Preferred
Stock shall have the following voting rights:

     (A)  Except as provided in paragraph C of this Section 3 and subject to
the provision for adjustment hereinafter set forth, each share of Series A
Preferred Stock shall entitle the holder thereof to 5000 votes (subject to
adjustment) on all matters submitted to a vote of the stockholders of the
Corporation.

                                        2



     (B)  Except as otherwise provided herein or by law, the holders of
shares of Series A Preferred Stock and the holders of shares of Common Stock
shall vote together as one class on all matters submitted to a vote of
stockholders of the Corporation.

     Section 4.     Certain Restrictions.

     (A)  Whenever quarterly dividends or other dividends or distributions
payable on the Series A Preferred Stock as provided in Section 2 are in
arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Series A Preferred Stock
outstanding shall have been paid in full, the Corporation shall not

          (i)       declare or pay dividends, or make any other distributions,
     on any shares of stock ranking junior (either as to dividends or upon
     liquidation, dissolution or winding up) to the Series A Preferred Stock;

          (ii)      declare or pay dividends, or make any other distributions,
     on any shares of stock ranking on a parity (either as to dividends or
     upon liquidation, dissolution or winding up) with the Series A Preferred
     Stock, except dividends paid ratably on the Series A Preferred Stock and
     all such parity stock on which dividends are payable or in arrears in
     proportion to the total amounts to which the holders of all such shares
     are then entitled;

          (iii)     redeem or purchase or otherwise acquire for consideration
     (except as provided in (iv) below) shares of any stock ranking junior
     (either as to dividends or upon liquidation, dissolution or winding up)
     to the Series A Preferred Stock, provided that the Corporation may at any
     time redeem, purchase or otherwise acquire shares of any such junior
     stock in exchange for shares of any stock of the Corporation ranking
     junior (either as to dividends or upon dissolution, liquidation or
     winding up) to the Series A Preferred Stock;

     (B)  The Corporation shall not permit any subsidiary of the Corporation to
purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section
4, purchase or otherwise acquire such shares at such time and in such manner.

     Section 5.     Reacquired Shares. Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and cancelled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock and may be reissued as part of a new series of Preferred Stock
subject to the conditions and restrictions on issuance set forth herein, in the
Certificate of Incorporation, in any other Certificate of Amendment creating a
series of Preferred Stock or as otherwise required by law.

                                        3



     Section 6.     Liquidation, Dissolution or Winding Up.

     (A)  Subject to the prior and superior rights of holders of any shares of
any series of Preferred Stock ranking prior and superior to the shares of
Series A Preferred Stock with respect to rights upon liquidation, dissolution
or winding up (voluntary or otherwise), no distribution shall be made to the
holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Preferred Stock unless,
prior thereto, the holders of shares of Series A Preferred Stock shall have
received $500.00 per share, plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment (the "Series A Liquidation Preference"). Following the payment of
                  ---------------------------------
the full amount of the Series A Liquidation Preference, no additional
distributions shall be made to the holders of shares of Series A Preferred
Stock unless, prior thereto, the holders of shares of Common Stock shall have
received an amount per share (the "Capital Adjustment") equal to the quotient
                                  --------------------
obtained by dividing (i) the Series A Liquidation Preference by (ii) 5,000 (the
"Adjustment Number"). Following the payment of the full amount of the Series A
- -------------------
Liquidation Preference and the Capital Adjustment in respect of all outstanding
shares of Series A Preferred Stock and Common Stock, respectively, holders of
Series A Preferred Stock and holders of Common Stock shall receive their
ratable and proportionate share of the remaining assets to be distributed in
the ratio of the Adjustment Number to 1 with respect to such Preferred Stock
and Common Stock, on a per share basis, respectively.

     (B)  In the event, however, that there are not sufficient assets available
to permit payment in full of the Series A Liquidation Preference and the
liquidation preferences of all other series of preferred stock, if any, which
rank on a parity with the Series A Preferred Stock, then such remaining assets
shall be distributed ratably to the holders of Series A Preferred Stock and the
holders of such parity shares in proportion to their respective liquidation
preferences. In the event, however, that there are not sufficient assets
available to permit payment in full of the Capital Adjustment, then such
remaining assets shall be distributed ratably to the holders of Common Stock.
Neither merger, consolidation, etc. shall be deemed to be a liquidation,
dissolution or winding up for purposes of this Section 6.

     (C)  In the event the Corporation shall (i) declare any dividend on Common
Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common
Stock, or (iii) combine the outstanding Common Stock into a smaller number of
shares, then in each such case the Adjustment Number in effect immediately
prior to such event shall be adjusted by multiplying such Adjustment Number by
a fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to
such event.

     Section 7.     Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case the shares of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed in an amount per share (subject to the provision for adjustment
hereinafter

                                        4



set forth) equal to 5,000 times the aggregate amount of stock, securities, cash
and/or any other property (payable in kind), as the case may be, into which or
for which each share of Common Stock is changed or exchanged. In the event the
Corporation shall at any time (i) declare any dividend on Common Stock payable
in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or
(iii) combine the outstanding Common Stock into a smaller number of shares,
then in each such case the amount set forth in the preceding sentence with
respect to the exchange or change of shares of Series A Preferred Stock shall
be adjusted by multiplying such amount by a fraction the numerator of which is
the number of shares of Common Stock outstanding immediately after such event
and the denominator of which is the number of shares of Common Stock that are
outstanding immediately prior to such event.

     Section 8.     No Redemption. The shares of Series A Preferred Stock shall
not be redeemable.

     Section 9.     Ranking. The Series A Preferred Stock shall rank junior to
all other series of the Corporation's Preferred Stock as to the payment of
dividends and the distribution of assets, unless the terms of any such series
shall provide otherwise.

     Section 10.    Amendment. The Certificate of Incorporation of the
Corporation shall not be further amended in any manner which would materially
alter or change the powers, preferences or special rights of the Series A
Preferred Stock so as to affect them adversely without the affirmative vote of
the holders of a majority or more of the outstanding shares of Series A
Preferred Stock, voting separately as a class.

                                        5
