An investor owned a 100-acre parcel that contained several natural asphalt lakes. A construction company was erecting highways for the state in the vicinity of the investor's land and needed a supply of asphalt. The investor executed a document that, in return for a payment of $1 per barrel, gave the company the right to enter on the land and take asphalt in whatever quantities the company desired. The investor reserved the right to remove asphalt herself and to grant this right to others. Last year, the state commenced an action in eminent domain to take the investor's land for a public park. Is the construction company entitled to compensation?
