Dear Belinda,

For the purposes of ASX Listing Rule 17.1, and in support of its request, SEA advises that:

1.              the trading halt is requested pending an announcement by SEA in relation to a potential corporate transaction and associated capital raising;

2.              it requests that the trading halt remain in place until the earlier of the time it makes an announcement to the market or the commencement of normal trading on Friday, 2nd February 2018; and

3.              it is not aware of any reason why the trading halt should not be granted or any other information necessary to inform the market about the trading halt.

Yours sincerely,
