Timko served on the board of trustees of a school. He recommended that the school purchase a building for a substantial sum of money, and to induce the trustees to vote for the purchase, he promised to help with the purchase and to pay at the end of five years the purchase price less the down payment. At the end of four years, Timko died. The school sued his estate, which defended on the ground that there was no consideration for the promise.

Assuming the estate is right on its theory of defending the claim against the school, is there any other theory or action the school could assert against Timko's estate to enforce the promise made by Timko?
