The well will be the subject of Petrostar's DHT (Down-Hole Tool) technology and will be re-entered and equipped with Petrostar's new 2nd generation more powerful DHT unit which is expected to be available for this location within the next 30-45 days weather permitting. Under the terms of the agreement Petrostar will advance the sum of $ 25,000.00 to Trigas for a 51% ownership in the lease and Petrostar will become the operator of the project. Petrostar will receive 100% of all funds expended for development and operating until payout at such time Trigas will be responsible for its 49 % share of any costs incur
