A legal mortgage arises when the assets are conveyed to the secured party as security for the obligations, but subject to a right to have the assets reconveyed when the obligations are performed. (Wikipedia)

Pledgor shall, on or before 15 days following its receipt of the Shares from the Secured Party pursuant to the preceding sentence, validly endorse the Shares in blank and deliver the Shares to the Secured Party, and agrees that the Shares shall concurrently be held in pledge by Secured Party hereunder to secure the Obligations.
