Alice and Bob formed Aztec, Inc. on February 1 to manufacture and market a product they recently patented. Cash to acquire equipment and working capital to begin its operations was obtained by selling 400,000 common shares to family, friends, and associates. Since then, Aztec has carried out its business in a building leased for one year under terms permitting Aztec to apply the first year's rental payments toward the fixed purchase price. Suitable manufacturing space is in short supply. According to Aztec's projections, it will run out of cash and exceed its established credit lines within a year. In early July, Aztec consults you about the possibility of raising $5 million through the sale of common stock to a group of sophisticated and experienced investors. The proceeds of this offering will be used for working capital and also will be added to the rental payments made thus far to satisfy the down payment required to purchase the building pursuant to the option's terms. Is Aztec engaged in one or two transactions?
