Sitting north, LHO opens 1S, 4D pre-empt from partner, 4S on right, you bid 5D (agree?), 5S on the left, passed round to you, what's your call? If you bid 6D, it goes P-P-6S. Now what?

You're the dealer, what's your plan? You are playing weak 2s. The meaning of 4NT is undiscussed, but assumably blacky.
If you pass, partner opens 1H (4cM 12-14 NT) and rebids the 2NT if you bid 2m to show 15-16. What would your rebid be?
EDIT: first hand had Axx in clubs, not Kxx. Incase that changes things.
