It is a contract to exercise ACO tokens without sending the amount required to exercise besides the ACO tokens. You send only the ACO tokens and the collateral to be obtained on exercise is partially used to buy the asset and pay the writers the expected amount, the user exercising receives the remaining amount (intrinsic value) This functionality on a unique transaction is possible due to Uniswap Flash Swap. It is only possible to flash exercise an ACO token whether there is the respective pair underlying / strike asset on Uniswap V2.
Function to get the required amount of collateral to be paid to Uniswap V2 as the first return and the expected amount to exercise the ACO token as the second return.

tokenAmount Amount of tokens to be exercised.
accounts The array of addresses to be exercised. Whether the array is empty the exercise will be considered as executed using the methods exercise or exerciseFrom.
