By 25 October 2018 at the very latest, Chen had decided to purchase Unit #06-08 of the Development (the “Property”). That is because on that day, Chen paid to TG a sum of S$514,700.00 by telegraphic transfer. That sum was a booking fee amounting to 10% of the Property’s purchase price of S$5,147,000.00 (the “Booking Fee”). TG received that payment on 30 October 2018, whereupon it granted Chen an Option to Purchase (“OTP”) in respect of the Property on the same day. In essence, the OTP was valid for 24 months from the date it was issued, and would (unless exercised) expire at 4.00pm on 30 October 2020 whereupon it would be null and void. In order to exercise the OTP, Chen had to sign that part of the OTP marked “ACCEPTANCE COPY” and deliver the same to TG’s solicitors before the expiry of the OTP, upon which a binding contract for the sale and purchase of the Property would be formed. A failure to exercise the OTP (among other things) would result in the forfeiture to TG of all payments made prior thereto (ie, payments amounting to 30% of the purchase price) (see [14] below). If the OTP was exercised, completion of the purchase of the Property would take place eight weeks after the date on which the OTP had been exercised and, on the date fixed for completion, the remaining 70% of the purchase price would have to be paid.
