            corporation and may authorize the seal of the corporation to be
            affixed to all papers which may require it; provided, in the absence
            or disqualification of any member of such committee or committees,
            the member or members thereof present at any meeting and not
            disqualified from voting, whether or not he or they constitute a

      preferences and relative, participating, optional or other special rights
      of each class of stock or series thereof and the qualifications,
      limitations or restrictions of such preferences and/or rights shall be set
      forth in full or summarized on the face or back of the certificate which
      the corporation shall issue to represent such class of stock; provided,
      however, that except as otherwise provided in Section 194 of the General
      Corporation Law of Delaware, in lieu of the foregoing requirements, there
      may be set forth on the face or back of the certificate which the

      corporation, whether because of death, resignation or otherwise, before
      such certificate or certificates have been delivered by the corporation,
      such certificate or certificates may nevertheless be adopted by the
      corporation and be issued and delivered as though the person or per-

 
      sons who signed such certificate or certificates or whose facsimile
      signature or signatures have been used thereon had not ceased to be such

      claiming the certificate of stock to be lost or destroyed. When
      authorizing such issue 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 and/or to give the corporation a bond in
      such sum 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.
