The limited partnership was organized in strict compliance with the limited partnership statute. Stevens was employed by the partnership as a purchasing agent. Stewart personally guaranteed a loan made to the partnership.

The partnership experienced serious financial difficulties, and its creditors seek to hold Webster, Stevens, and Stewart personally liable for the debts of the partnership. Who, if any, is personally liable?
