The Red Hat Enterprise Agreement works in complement with the Gnu General Public License (GPL).The GPL is a license agreement that defines how the software may be used, modified, and distributed by a customer.

The Red Hat Enterprise Agreement describes the scope of Red Hat subscription — i.e., the value that Red Hat provides to customers in the form of certified software, support, updates and upgrades, and intellectual property assurances — and the payments that a customer makes in exchange for the subscription. The Red Hat Enterprise Agreement incorporates the GPL into our End User License Agreement (EULA).
