Item 1.01 Entry into a Material Definitive Agreement

         On May 9, Natural Gas Systems, Inc. ("NGS" or the "Company"), through
our wholly-owned subsidiary NGS Sub Corp, entered into a Purchase and Sale
Agreement (the "Sale Agreement") with Denbury Onshore, LLC., an indirect
subsidiary of Denbury Resources, Inc. (NYSE symbol: DNR, hereinafter referred to
as "Denbury") to conduct an enhanced oil recovery project in the Company's Delhi
Holt Bryant Unit within the Delhi Field in northeast Louisiana (the "Delhi
Unit"). NGSY will contribute its working interest in the Delhi Unit, and Denbury
will contribute all development capital, technical expertise and required
amounts of proven reserves of carbon dioxide that will be injected into the oil
reservoirs. The principal terms of the Sale Agreement call for NGS to receive
$50 million at closing, subject to adjustments, if any, following normal due
diligence inspections. The closing is subject to customary closing conditions
and is scheduled to occur on May 31, 2006. At closing, NGS will deliver to
Denbury an initial 100% working interest and 80% net revenue interest in the
Delhi Unit, while retaining a separate 4.8% royalty interest within the Delhi
Unit and a 25% working interest in other depths. After the project generates
$200 million of net cash flows before capital expenditures for Denbury, NGS will
regain a 25% working interest (20% net revenue interest) in the Delhi Unit.


         The foregoing description is qualified by reference to Exhibit 10.1 to
this Current Report on Form 8-K, which Exhibit is incorporated herein by
reference. In connection with the Sale Agreement, the Company issued a press
release on May 9, 2006, which is included herewith as Exhibit 10.2.
