Xerox Corp. (NYSE: XRS) announced on Monday that it would buy Global Imaging Systems (Nasdaq: GISX), sending shares of the Tampa-based company skyrocketing.

The firm agreed to be acquired by Xerox for $29 a share or about $1.5 billion. It is a premium of about 49 percent over Global Imaging's Friday closing price of $19.50. Shares of the company shot up $9.15, or 46.9 percent to $28.65 in Monday afternoon trading on the Nasdaq Stock Market.

Global Imaging serves the printer and copier needs of nearly 200,000 customers across the U.S. generating more than $1 billion in annual sales.
