Northwest Airlines leased space in the terminal building at the Portland Airport from the Port of Portland. Crosetti entered into a contract with the Port to furnish janitorial services for the building, which required Crosetti to keep the floor clean, to indemnify the Port against loss due to claims or lawsuits based upon Crosetti's failure to perform, and to provide public liability insurance for the Port and Crosetti.

A patron of the building who was injured by a fall caused by a foreign substance on the floor at Northwest's ticket counter brought suit for damages against Northwest, the Port, and Crosetti.

Upon settlement of this suit, Northwest sued Crosetti to recover the amount of its contribution to the settlement and other expenses on the grounds that Northwest was a third-party beneficiary of Crosetti's contract with the Port to keep the floors clean and, therefore, within the protection of Crosetti's indemnification agreement. Will Northwest prevail? Why?
