Transferee liability for partly paid securities: transferee notified and liable to pay unpaid balance unless objection is raised. The company must notify the transferee that the securities are partly paid and that the transferee shall be liable to pay the balance unpaid; the notice must provide particulars of transferor and transferee, class and number of securities, distinctive and certificate numbers, nominal and issue price, amounts called and paid, uncalled amounts and aggregate called and uncalled sums, and invite objections within a short specified period, failing which the transfer will proceed.
