[1] Royalty obligations primarily represent our obligations under our non-cancelable agreements related to software used in certain revenue-generating agreements.

[2] Purchase commitments consist of agreements to purchase services, entered into in the ordinary course of business. These represent non-cancelable commitments for which a penalty would be imposed if the agreement was canceled for any reason other than an event of default as described by the agreement.
