providing for the issue of such series: 

         (a) The number of shares to constitute such series and 
             the distinctive designation thereof;


                              - 5 -

 
         (b) The dividend rate on the shares of such series and 
             the date or dates from which dividends shall 
             accumulate;

         (c) The amount per share over and above any accumulated 
             dividends thereon which the shares of such series 
             shall be entitled to receive upon redemption;

         (d) The amount per share over and above accumulated 
             dividends which such series shall be entitled to 
             receive (1) upon involuntary liquidation or 
             dissolution or winding-up of the corporation, which 
             amount shall not exceed $100.00 a share, and 
             (2) upon voluntary liquidation or dissolution or 
             winding-up of the corporation; and

         (e) The rights, if any, which the shares of such series 
             may have for conversion into shares of any other 
             class or classes or any other series of the same or 
             any other class or classes of stock of the 
             corporation.

     All shares of any one series of Preferred Stock shall be 
identical with each other in all respects, except that shares of 
any one series issued at different times may differ as to the 
dates from which the initial dividends thereon shall accumulate; 
and all series shall rank equally and be identical in all 
respects, except as permitted in the foregoing provisions of 
this Section III.

     IV.  The Preferred Stock shall entitle the holders thereof 
to receive, when and as declared from the surplus or net 
earnings of the corporation, cumulative dividends, payable 
quarterly on such dates as the Board of Directors may determine, 
at the rates fixed herein or fixed by the Board of Directors for 
the respective series, as herein provided, and no more, which 
dividends shall be paid or set apart before any dividend shall 
be set apart or paid on the Common Stock.  The dividend payment 
dates for all series of Preferred Stock shall be the same and no 
dividends shall be declared on any series in respect of any 
quarterly dividend payment unless there shall likewise be or 
have been declared on all shares of Preferred Stock of each 
other series at the time outstanding like proportionate 
dividends ratably in proportion to the respective annual 
dividend rates fixed therefor.

     V.  In the event of any liquidation or dissolution or 
winding-up of the corporation, whether voluntary or involuntary, 
the Preferred Stock shall entitle the holders thereof to be paid 
the amounts fixed herein or fixed by the Board of Directors for 


                              - 6 -

 
the respective series as herein provided, including all unpaid 
accumulated dividends thereon to the date of such payment, 
before any amount shall be paid to the holders of the Common 
Stock of the corporation.

     Such payments to the holders of the Preferred Stock shall 
be made without preference or priority of one series over any 
other series and shall be made before any amount shall be paid 
to the holders of the Common Stock.  If the assets of the 
corporation distributable upon any such liquidation or dissolu- 
tion or winding-up of the corporation shall be insufficient to 
permit the payments to the holders of the Preferred Stock of the 
full amounts above provided for, including an amount equivalent 
to all unpaid accumulated dividends as aforesaid, the said 
assets shall be allocated to the respective series of Preferred 
Stock in the ratios that such aggregate liquidation value of the 
issued shares of each series bears to the aggregate liquidation 
value of the issued shares of all series of Preferred Stock as 
fixed for the respective series of Preferred Stock in the 
Certificate of Incorporation or in the resolution or resolutions 
of the Board of Directors providing for the issuance of the 
respective series, and shall be distributed among the holders of 
the respective series of Preferred Stock according to their 
respective shares. 

     VI.  The Preferred Stock of any series shall be subject to 
redemption at any time in whole or in part at the amount fixed 
herein, or fixed by the Board of Directors as herein provided, 
for the redemption of such series including an amount equivalent 
to all unpaid accumulated dividends thereon, upon not less than 
sixty days' notice addressed to the respective holders of record 
of the stock to be redeemed at their addresses as the same shall 
appear on the stock transfer records of the corporation in such 
manner as the Board of Directors shall determine.

     VII.  The holders of the Preferred Stock shall have no 
voting power on any questions whatsoever except as otherwise 
provided by law, and except that in the event that the 
corporation shall fail to pay any dividend on the Preferred 
Stock when it regularly becomes due and such default shall 
continue for the period of six (6) months, then until but not 
after such time as accumulated and unpaid dividends on all 
outstanding Preferred Stock of all series shall have been paid, 
the holders of the outstanding Preferred Stock shall have the 
exclusive right, voting separately and as a class, to elect two 
directors or, if the total number of directors of the corpora- 
tion be only three, then only one director, at each meeting of 
the stockholders of the corporation held for the purpose of 
electing directors.  At all meetings of stockholders held for 
the purpose of electing directors at which the holders of 


                              - 7 -

 
Preferred Stock shall have the exclusive right, voting 
separately and as a class, to elect any directors as aforesaid, 
the presence in person or by proxy of the holders of a majority 
of the outstanding shares of Preferred Stock shall be required 
to constitute a quorum of such class for the election of any 
directors by holders of Preferred Stock, as a class, provided, 
however, that the absence of a quorum of the holders of 
Preferred Stock shall not prevent the election at any such 
meeting or adjournment thereof of the remaining directors for 
whose election a class vote of the holders of Preferred Stock is 
not required, if the necessary quorum of the stockholders 
entitled to vote in the election of such remaining directors is 
present in person or by proxy in accordance with the by-laws of 
the corporation; and provided further, that in the absence of a 
quorum of the holders of Preferred Stock, a majority of those 
holders of such Preferred Stock who are present in person or by 
proxy shall have power to adjourn the election of those 
directors to be elected by their class from time to time without 
notice other than announcement at the meeting until the 
requisite amount of holders of Preferred Stock shall be present 
in person or by proxy.

     The holders of Common Stock shall have the right to vote on 
all questions to the exclusion of all other stockholders except 
as hereinbefore specifically stated.

     VIII.  Whenever, at any time, full accumulated dividends as 
aforesaid for all past dividend periods and for the current 
dividend period shall have been paid, or declared and set apart 
for payment, on the then outstanding Preferred Stock, the Board 
of Directors may declare dividends on the Common Stock of the 
corporation.

     IX.  Upon any liquidation or dissolution or winding-up of 
the corporation, whether voluntary or involuntary, the assets 
and funds of the corporation remaining, after the payments have 
been made to the holders of the Preferred Stock, as provided in 
Section V hereof, shall be divided and paid to the holders of 
the Common Stock according to their respective shares.

     X.  From time to time the Preferred Stock or the Common 
Stock may be increased according to law.

     XI.  From time to time the Preferred Stock and the Common 
Stock may be issued in such amounts and proportions and for such 
consideration as may be fixed by the Board of Directors, or, in 
the case of Common Stock issued upon the exercise of the options 
referred to in Section XIII hereof, as provided in such Section.


                              - 8 -

 
     XII.  No stockholder of the corporation, of whatever class 
or series, shall have any preemptive or preferential right of 
subscription to any shares of any series of the Preferred Stock 
of the corporation, authorized hereunder or under any amendment 
hereof, or to any obligations convertible into said Preferred 
Stock of any series of the corporation, issued or sold, nor any 
right of subscription to any thereof other than such, if any, as 
the Board of Directors of the corporation in its discretion from 
time to time may determine, and the Board of Directors may issue 
said Preferred Stock of any series of the corporation, or 
obligations convertible into said Preferred Stock of any series, 
without offering said Preferred Stock, or said obligations, 
either in whole or in part, to any stockholders of the 
corporation.

     No holder of any shares of the Preferred Stock of any 
series of the corporation shall have any preemptive or preferen- 
tial right of subscription to any shares of stock of any class 
of the corporation, or to any obligations convertible into 
shares of stock of any class of the corporation, issued or sold, 
nor any right of subscription to any thereof other than such, if 
any, as the Board of Directors of the corporation in its 
discretion from time to time may determine.

     XIII.  The Board of Directors may create and issue to 
employees (including officers and directors) of this corpora-

meeting.

     (j) With the written assent, without a meeting of the 
holders of two-thirds of its stock, or pursuant to the 
affirmative vote, in person or by proxy, at any meeting called
