treat the holder of record of any shares as the holder in fact thereof and

certificate be issued in place of any certificate previously issued by the
Corporation alleged to have been destroyed or lost, upon the making of an
affidavit of that fact by the person claiming that the share certificate was

new certificate may, in its discretion and as a condition precedent to the
issuance thereof require the owner of such lost or destroyed certificate, or his
legal representative to advertise the same in such manner as it shall require
and/or give the Corporation a bond in such sum as it may direct as indemnity
against any claim that may be made against the Corporation.
