You are entitled to evaluate the Licensed Products for 30 days only.

At or before the end of the 30-day evaluation period you agree to either purchase license(s) for the Licensed Products, or you must discontinue the use of all Licensed Products, remove all software from all computers, including all copies, and agree that you will not use the Licensed Products in any product (internal or commercial) after the expiration of the 30-day evaluation period.
