The 6% liquidation damages come to $108,000, but with the $90,000 deposit already made, Adrian owes an additional $18,000. Adrian's financing contingency defense doesn't hold up because the notice came too late on day 12 when it required five days' notice, and the termination notice on day 24 missed the contingency deadline of day 20. The seller can't recover actual damages, carrying costs, or attorney fees under the contract terms, so the total liability is capped at the liquidated damages amount.
