On May 1, 2019, BuildCo and HotelCo formed a contract by which BuildCo was to build a hotel and complete its work by February 28, 2021. In exchange, HotelCo was to pay BuildCo $30 million. Knowing of HotelCo's plan to open a hotel, GasCo opened a gasoline station near the building site. GasCo speculated that the hotel would bring it business. In July 2020, GasCo learned that BuildCo was in financial difficulty and might fail to complete the hotel by February 28, 2021. On July 15, GasCo wrote to BuildCo: "We know, of course, that you are building a hotel for HotelCo, and we have heard that financial difficulties might prevent you from doing so. We make this proposal: If you will promise to complete the hotel by February 28, 2021 we will promise to pay you $2 million, beyond the moneys that HotelCo is to pay you." BuildCo wrote back: "Agreed. We will timely complete the hotel." On February 28, 2021, BuildCo completed the hotel. HotelCo has paid BuildCo $30 million, and BuildCo now demands $2 million from GasCo. Is GasCo obliged to pay BuildCo $2 million?
