     for trading; and provided, further, that no amendment, suspension or

amendments do not require approval of the Stockholders of the Company and,
accordingly, the amendments will not be submitted to the Stockholders of the
Company and shall become effective this date.
 
     The Board of Directors of the Company approved the foregoing amendments on
November 5, 1996.
