The Company is party to a loan agreement with Prospect Energy Corporation pursuant to which Prospect has loaned the Company $5.0 million. On May 16, 2006, the Company notified Prospect that, although the exact ratio has not yet been determined, the Company's interest coverage ratio was less than 2.0:1.0 for the three months ended April 30, 2006, and that the debt service reserve was not fully funded as required by the terms of the loan agreement. Although the Company has otherwise remained current on required payments of principal and interest on the loan, an event of default has occurred, and the loan is currently payable in full. As a result, the Company will record approximately $1.2 million of additional non-cash interest expense for the quarter ended March 31, 2006 and reclassify the loan from a long-term to a current obligation. As a short- term obligation, the Company is not permitted to amortize the loan discount over the original life of the loan. The Company has been in discussions with Prospect regarding the loan and the possibility of obtaining temporary relief from this technical breach. In the event terms for such relief are not mutually agreed to, the Company currently has sufficient funds available to repay the principal and accrued interest on the loan. The Company also anticipates the following changes to its operations from the corresponding period in the prior year: In the most recent three months ended March 31, 2006, the Company's sales volumes and revenues have increased by 74% and 132%, respectively, over the prior year three-month period. For the nine months ended March 31, 2006, sales volumes and revenues have increased by 85% and 131%, respectively, over the prior year nine-month period. When combined with lease operating expenses and production taxes, field income before depletion expense increased 134% and 115% for the comparable three and nine months ended March 31, 2006, respectively, while general and administrative expenses declined 31% and rose 8%, respectively for the same periods. Losses from operations declined 49% and 9% for the comparable three and nine month periods. Due to the $1.2 million additional non-cash interest charge taken in the three months ended March 31, 2006, the Company's net loss increased 98% and 87% for the comparable three and nine month periods. The foregoing are estimates only based on information currently available to the Company. Natural Gas Systems, Inc. (Name of Registrant as Specified in Charter) has caused this notification to be signed on its behalf by the undersigned hereunto duly authorized.
