These agreements are like shareholder agreements, except they focus on the purchase of a company's equity by a discrete group of purchasers following formation. These contracts can include such features as buy-back provisions, sale proceeds distribution schedules, and other features which can protect the purchasing shareholder's position while concurrently giving the necessary flexibility to the business to continue its operation over an extended period. A well balanced contract will allow the business to accept additional financing via stock sale, while not mortgaging its future entirely to a single investor.
