Minimum Requirements for 11.5.10 Extended Support

While Premier Support for 11i ends in November 2010, Extended Support will pick up and be available for free until November 2011.

Current bug fixes will continue to be available for older patch levels. However, EBS customers must meet a minimum baseline patch level in order to receive any new bug fixes. The minimum baseline requirement is spelled out in:

Please note that, per the doc, the baseline versions may change in the future and any such changes will be communicated in the document.
