BUSINESS OPERATIONS	1. BUSINESS OPERATIONS ImmuCell Corporation (the "Company", "we", "us", "our") was originally incorporated in Maine in 1982 and reincorporated in Delaware in 1987, in conjunction with our initial public offering of common stock. We are an animal health company whose purpose is to create scientifically-proven and practical products that improve the health and productivity of dairy and beef cattle. We manufacture and market the First Defense^® product line for the prevention of scours in newborn dairy and beef calves. We are developing improved formulations of this product line providing Immediate Immunity™ to newborn calves and are in the late stages of developing Re-Tain™, a treatment for cows with subclinical mastitis, the most significant cause of economic loss to the dairy industry. These products help reduce the need to use traditional antibiotics in food producing animals. We are subject to certain risks associated with this stage of development including dependence on key individuals and third-party providers of critical goods and services, competition from other larger companies, the successful sale of existing products and the development and acquisition of additional commercially viable products with appropriate regulatory approvals, where applicable. Based on our best estimates and projections, we believe that we have sufficient capital resources to continue operations for at least twelve months from the date of this filing.
