Update on Talitha #A Well Operations

Pantheon has released an operations update for the Talitha #A well. This update indicates that Pantheon has successfully set a liner in the Kuparuk interval of the well, has perforated the Kuparuk interval and well testing operations are expected to commence shortly.

Pantheon has advised that it expects to provide an update on the completion of the initial phase of testing operations early next week. As Pantheon has previously announced, oil has been encountered in the Kuparuk Formation which is a major regional producer on the Alaska North Slope, and a successful test would represent a significant event for Pantheon.

Otto looks forward to the ongoing progress of the Talitha #A well, including imminent testing of the Kuparuk section, as well as possible testing of additional zones in the well.

Otto Executive Chairman, Mike Utsler, commented: 'Otto congratulates Pantheon on its excellent operational performance with the Talitha #A well and its preliminary success. We look forward with optimism, and as a Pantheon shareholder, to the imminent well test operations in the highly prospective Kuparuk interval.'

This announcement has been approved for release by the Company's Board of Directors.
