By the development agreement, Mrs. Campbell agreed to assign the lease to Appellant, which undertook to furnish the necessary management for the development of the leasehold lands by increments and the promotion and sale to the public of improvements thereon and to be responsible for advancing all costs of the development. Appellant agreed immediately to enter into negotiation with the trustees of the Campbell Estate for an extension of the lease and cancellation of the provisions for early termination as to the 21.70 acres. Mrs. Campbell was entitled to a month-to-month tenancy of the lands while not required for development, at the lease rental.
