The resale of the Flat is independent of the Temporary Extension of Stay. The legal
completion of the resale of the Flat will still take place regardless of the status of the
Temporary Extension of Stay.

1）This request is subject to the Buyers agreeing to allow sellers to stay
temporarily in the Flat after the resale completion of the Flat and HDB granting approval to
this private arrangement.

2) either Sellers or the Buyers may cancel the private arrangement for the
Temporary Extension of Stay at any time before the resale completion date of the Flat,
notwithstanding that HDB’s approval to the same may already have been given.

3) In the event that the Sellers and/or the authorised occupiers do not vacate the Flat at
the end or upon the termination of the Temporary Extension of Stay, the Buyers shall
be required to initiate their own actions as the owners of the Flat and at their own
costs and expenses to evict the Sellers and/or the authorised occupiers from the Flat
