                 The holders of the Series A Preferred Stock shall have the
following rights and preferences:

apart for such Series A Preferred Stock, any dividends or distributions of the
Corporation in respect thereof.
 
         (b)     Liquidation, Dissolution and Winding Up.  In the event of any
voluntary or involuntary liquidation, dissolution or winding up of the affairs
of the Corporation, the holders of the Series A Preferred Stock shall be

Corporation shall be made to the holders of any other outstanding shares of the
Corporation, unless funds necessary for such payment shall have been set aside
in trust for the account of the holders of outstanding shares of Series A
Preferred Stock so as to be and continue to be available therefor.  The holders
of shares of Series A Preferred Stock shall be entitled to no further
participation in any distribution of the assets of the Corporation.  If upon
such liquidation, dissolution or winding up, the assets of the Corporation
distributable as aforesaid among the holders of shares of Series A Preferred
Stock are insufficient to permit the payment to holders of Series A Preferred
Stock of $100.00 per share then the assets of the Corporation shall be
distributed to the holders of shares of Preferred Stock ratably according to
their respective shares until they shall have received the full amount to which
they would otherwise be so entitled.
 
         (c)     Redemption.  No shares of Series A Preferred Stock shall be
callable or redeemable by the Corporation.  Any shares of Series A Preferred
Stock purchased or otherwise acquired by the Corporation shall have the status
of treasury shares of Preferred Stock until such time as such shares are
cancelled pursuant to the provisions of the Act.
 
         (d)     Voting.  Each share of Series A Preferred Stock shall entitle
the holder thereof to one-tenth (1/10) of one vote on each matter presented to

matter except as required by law.

the shares of Series A Preferred Stock shall not have any powers, preferences,
or relative, participating, option or other special rights other than those
specifically set forth herein.
 
         3.      Series B Preferred Stock
 
                 The holders of the Series B Preferred Stock shall have the
following rights and preferences:
 
         (a)     Dividends.  The holders of the Series B Preferred Stock shall
be entitled to receive dividends out of any funds legally available for that
purpose at the annual rate of six percent (6%) per annum of the stated value
and no more.  These dividends are payable in cash monthly on the last day of
each month.  The first dividend, after the issuance of such shares, shall be
payable on the last day of the month of issuance.  Dividends will accrue from
the date the shares of Series B Preferred Stock are issued and are considered
to accrue from day to day, whether or not earned or declared.  The dividends
will be payable before any dividends are paid, declared, or set apart for any
other capital stock of the Corporation.  Dividends are cumulative so that if
for any dividend period the dividends on the outstanding Series B Preferred
Stock are not paid or declared and set apart, the deficiency shall be fully
paid or
 
 
 
 
 
                                      -3-

Stock shall not be entitled to receive any other dividends or distributions.
 
         (b)     Liquidation, Dissolution and Winding Up.  Subject to the

of the Corporation, the holders of outstanding shares of Series B Preferred
Stock shall be entitled to receive $100.00 in cash for each share, before any
distribution of the assets of the Corporation shall be made to the holders of
any other class or series of shares of the Corporation unless funds necessary
for such payment shall have been set aside in trust for the account of the
holders of outstanding shares of Series B Preferred Stock so as to be and
continue to be available therefor.  If upon such liquidation, dissolution or
winding up, the assets of the Corporation distributable as aforesaid among the
holders of shares of Series B Preferred Stock are insufficient to permit the
payment to the holders of outstanding shares of Series B Preferred Stock of
$100.00 per share, then the assets of the Corporation shall be distributed to
the holders of outstanding shares of Series B Preferred Stock ratably according
to their respective shares until they shall have received the full amount to
which they would otherwise be so entitled.  The holders of the Series B
Preferred Stock shall also be entitled to participate on a pro rata basis
(based on the outstanding number of shares) in any distributions made to the
holders of the Common Stock or other class or series of stock that is entitled
to distributions upon satisfaction of all shares entitled to preferred
distribution.
 
         (c)     Redemption.
 
                 (i)      The Corporation, at the option of the Board of
Directors, may at any time five (5) years from the date of initial issuance
redeem the whole, or any part, of the outstanding shares of Series B Preferred
Stock by paying $100.00 per share plus all dividends accrued, unpaid, and
accumulated as provided in this Article through and including the redemption
date and by giving to each record holder of Series B Preferred Stock, at his or
her last known address as shown in the Corporation's records, at least twenty
but not more than sixty days' notice.  This redemption notice may be delivered
either in person or in writing, by mail, postage prepaid and must state the
shares to be redeemed, along with the date and plan of redemption, the
redemption price, and the place where the shareholders may obtain payment of
the redemption price on surrendering their share certificates.  If only a part
of the outstanding shares of Series B Preferred Stock shares are redeemed,
redemption will be pro rata.  No shares of Series B Preferred Stock may be
redeemed unless all accrued dividends on all outstanding shares of Series B
Preferred Stock shares have been paid for all past dividend periods and full
dividends for the current period, except those to be redeemed, have been paid
or declared and set apart for payment.  On or after the date fixed for
redemption, each holder of shares called for redemption must, unless the
shareholder has previously exercised the option to convert the holder's shares
of Series B Preferred Stock as provided herein, surrender to the Corporation
the certificate for the shares at the place designated in the redemption notice
and will then be entitled to receive payment of the redemption price.  If fewer
than all the shares represented by any surrendered certificate are redeemed, a
new certificate for the unredeemed shares will be issued.  If the redemption
notice is duly given and sufficient funds are available to pay all monies
herein required on the date fixed for redemption, then, whether or not the
certificates representing the shares to be redeemed are surrendered, all rights
with respect to the shares shall terminate on the date fixed for redemption,
except for the holders' right to receive the redemption price, without
interest, on surrendering their certificates.

                 (ii)     Shares are considered redeemed, and dividends on them
cease to accrue after the date fixed for redemption, if, on or before any date
fixed for redemption of the shares of Series B Preferred Stock as provided
herein, the Corporation deposits as a trust fund with any bank or trust company
a sum sufficient to redeem, on the date fixed for redemption, with irrevocable
instructions and authority to the bank or trust company (a) to publish the
redemption notice (or to complete publication already begun), and (b) to pay,
on and after the date fixed for redemption or before that date, the redemption
price of the shares to their holders when they surrender their certificates.
The deposit is considered to constitute full payment of the shares to their
holders, and from the date of the deposit the shares will no longer be
considered outstanding.  Moreover, the holders of the shares will cease to be
shareholders with respect to the shares and will have no rights with respect to
the shares, except to receive from the bank or trust company payment of the
redemption price of the shares (without interest) on surrendering of the
certificates unless the shares are converted to Common Stock, as provided
herein.  Any money so deposited on account of the redemption price of Series B
Preferred Stock share which are converted after the deposit is made must be
repaid immediately to the Corporation on conversion of the Series B Preferred
Stock.
 
                 (iii)    Share of Series B Preferred Stock redeemed by the
Corporation shall be restored to the status of authorized but unissued shares.
 
         (d)     Conversion.
 
                 (i)      At any time prior to the redemption of any share of
Series B Preferred Stock, the holder of such shares of Series B Preferred Stock
shall have the right to convert such share into 112 shares of Common Stock.
The right to receive the converted shares requires delivery to the office of
the Corporation or its transfer agent of the shareholder's written notice
stating the number of shares the shareholder is electing to convert.  Said
notice shall be accompanied by the surrender of the Series B Preferred Stock
certificate or certificates, duly endorsed to the Corporation.  The date of
conversion shall be the date of receipt by the Company or its transfer agent of
the notice and the duly endorsed certificate(s).
 
                 (ii)     Neither fractional shares nor scrip or other
certificates representing the shares may be issued by the Corporation on
conversion of shares of Series B Preferred Stock, but the Corporation must pay
in lieu thereof the full value in cash to the holders who would be entitled to
receive the fractional shares but for this provision.
 
                 (iii)    The Corporation must at all time reserve out of its
authorized but unissued shares of Common Stock the full number of shares
deliverable on conversion of all shares hereunder from time to time
outstanding.  Said shares are reserved solely for the purpose of satisfying the
conversion requirements.
 
                 (iv)     The number of shares and securities or other property
issuable upon the conversion of the Series Preferred Stock shall be subject to
adjustment from time to time in the event of any reclassification of the Common
Stock, the issuance of any stock dividend or stock split in respect of the
Common Stock, share exchange involving the Common Stock or other similar
transaction so that the holders of the Series B Preferred Stock shall be
entitle to receive on conversion of the shares of Series B Preferred Stock that
number of shares and other securities or property that a holder of a share of
Common Stock received in such reclassification, stock dividend, stock split,
share exchange or similar transaction.  Such adjustments shall be determined by
the Board of Directors of the Corporation, whose determination shall be final
and conclusive.  Such adjustments shall be made for successive transactions.

the Series A Preferred Stock shall not be entitled to vote as a class on any
matter except as required by law.
 
         (e)     Exclusion of Other Rights.  Unless otherwise required by law,
the shares of Series A Preferred Stock shall not have any powers, preferences,
or relative, participating, option or other special rights other than those
specifically set forth herein.

Stock is $100 per share, all of which shall be allocated to the stated capital
of the Corporation.
 
         4.      Future Designations
 
         Subject to the provisions of paragraph A of this Article IV, the Board
of Directors of the Corporation is hereby vested with authority from time to
time to establish and designate such series of Preferred Stock from the
authorized but unissued shares of Preferred Stock as it may deem desirable, and
within the limitations prescribed by law or set forth herein, to fix and
determine the relative rights and preferences of the shares of any series so
established. The Board of Directors shall exercise such authority by the
adoption of a resolution or resolutions as prescribed by law, setting forth the
designation of the series and fixing and determining the relative rights and
preferences thereof or so much thereof as shall not be fixed and determined
herein. The Board of Directors may increase or decrease the number of shares of
a series by adopting a resolution fixing and determining the new number of
shares of each series in which the number of shares is increased or decreased;
provided, however, no decrease may reduce the number of shares within a series
to less than the number of shares within such series that are then issued.

majority of the shares entitled to vote and represented at a meeting at which a
quorum is present shall be the act of the shareholders' meeting, except with
respect to certain actions, which require the affirmative vote of the holders
of a majority of the outstanding shares of the Corporation unless any class of
stock of the Corporation is entitled to vote as a class thereon, in which event
the action shall be approved upon the affirmative vote of the holders of a
majority of the outstanding shares within each class entitled to vote as a
class thereon as well as a majority of the outstanding shares. No shareholder
of the Corporation shall have the right of cumulative voting at any election of
directors or upon any other matter.

otherwise. Any such securities may be issued or disposed of by the Board of
