Organization and Business	Note 1 - Organization of Business and Going Concern: Generex Biotechnology Corporation (the Company) and its wholly-owned subsidiary Generex Pharmaceuticals, Inc. has been engaged in the research and development of drug delivery systems and technology. Since its inception, the Company has devoted its efforts and resources to the development of a platform technology for the oral administration of large molecule drugs, including proteins, peptides, monoclonal antibodies, hormones and vaccines, which historically have been administered by injection, either subcutaneously or intravenously. The Company’s wholly-owned subsidiary, Antigen Express, Inc. (Antigen), has been engaged in research and development of technologies and immunomedicines for the treatment of malignant, infectious, autoimmune and allergic diseases. The Company’s immunomedicine products work by stimulating the immune system to either attack offending agents (i.e., cancer cells, bacteria, and viruses) or to stop attacking benign elements (i.e., self proteins and allergens). The immunomedicine products are based on two platform technologies that were discovered by an executive officer of Antigen, the Ii-Key hybrid peptides and Ii-Suppression. These technologies are expected to greatly boost immune cell responses which diagnose and treat the ailments and conditions. The Company has a limited history of operations and limited revenue to date. Although the Company has had several product candidates that are in various research or early stages of pre-clinical and clinical development, due to its lack of funding the Company has effectively ceased these operations and is now seeking new investment opportunities (see Note 15). There can be no assurance that the Company will be successful in completing these investment opportunities and maintaining its position as a going concern.
