                                 CAPITAL STOCK

     Section 1.   Certificates of Stock.   Every stockholder shall be entitled
to have a certificate signed by, or in the name of the Corporation by (i) the
Chief Executive Officer or the President and (ii) the Secretary or the
Assistant Secretary of the Corporation, certifying the number of
     




                                       11
   12
shares of stock of the Corporation owned by him.  The certificate shall be
sealed with the seal of the Corporation, or a facsimile thereof.  No
certificate shall be issued for any share until such share is fully paid.  Each
certificate representing shares shall state that the Corporation is organized
under the laws of the State of Delaware, the name of the person to whom issued,
the par value of each share represented by such certificate or a statement that
the shares are without par value, the class and type of shares represented by
such certificate, and shall contain such legend or legends restricting the
transfer or otherwise as the Corporation shall deem appropriate.  Until such
time as the Corporation registers its stock under the Securities Act of 1933,
as amended, each stock certificate issued by or on behalf of the Corporation
shall have written, stamped, printed, or otherwise affixed on the face or back
thereof a legend, stating in substance:

     The shares represented by this Certificate have not been registered under
     the Securities Act of 1933, as amended, and may be offered and sold only 
     if registered pursuant to the provisions of that Act or if any exemption 
     from registration is available.  The shares represented by this 
     Certificate may not be transferred unless the holder hereof shall have
     complied with all provisions of the Certificate of Incorporation and any 
     applicable agreement with the Corporation and/or stockholders of the 
     Corporation affecting the sale thereof.

     Section 2.   Transfers of Capital Stock.   Stock certificates shall be
transferable on the stock books of the Corporation in person or by attorney,
but, except as hereinafter provided in the case of loss, destruction or
mutilation of certificates, no transfer of stock shall be entered until the
previous certificate, if any, given for the same shall have been surrendered
and canceled.   No transfer of shares of the capital stock of the Corporation
shall be effective until such transfer is recorded on the stock transfer books
of the Corporation.  Until a transfer of shares of the capital stock of the
Corporation is recorded on the stock transfer books of the Corporation, the
record owner of such shares shall have the sole and exclusive right to vote
such shares upon all matters regarding which such shares are entitled to vote,
in accordance with the provisions of Article II.
     
     Section 3.   Closing of Transfer Books.  For the purpose of determining
stockholders entitled to notice of or to vote at any meeting of stockholders,
or stockholders entitled to receive payment of a dividend, or in order to make
a determination of stockholders for any proper purpose, the
     




                                       12
   13
Board of Directors may provide that the stock transfer books shall be closed
for a stated period but not to exceed, in any case, sixty (60) days.  If the
stock transfer books shall be closed for the purpose of determining
stockholders entitled to notice of or to vote at a meeting of stockholders,
such books shall be closed for at least ten (10) days immediately preceding
such meeting.  In lieu of closing the stock transfer books, the Board of
Directors may fix in advance a date as the record date for any determination of
stockholders, such date in any case to be not more than sixty (60) days, and in
case of a meeting of stockholders not less than ten (10) days prior to the date
upon which the particular action requiring such determination of stockholders
is to be taken.  If no record date is fixed for the determination of
stockholders, the date next preceding the date on which notice of the meeting
is mailed or the date on which the resolution of the Board of Directors
declaring such dividends is adopted, as the case may be, shall be the record
date for such determination of stockholders.

     Section 4.   Lost, Destroyed or Mutilated Certificates.  The Board of
Directors may direct a new certificate or certificates to be issued in place of
any certificate or certificates heretofore issued by the Corporation alleged to
have been lost, destroyed or mutilated upon the making of an affidavit of that
fact by the person claiming the certificates for shares to be lost or
destroyed.  When authorizing such issuance of  a new certificate or
certificates, the Board of Directors may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost or destroyed
certificate or certificates, or his legal representative, to advertise the same
in such manner as it shall require, or to give the Corporation a bond in such
sums as it may direct, as indemnity against any claim that may be made against
the Corporation with respect to the certificate alleged to have been lost or
destroyed.
