ITEM 1.02 TERMINATION OF A MATERIAL DEFINITIVE AGREEMENT

            As previously reported in a Current Report on Form 8-K filed by
Natural Gas Systems, Inc. ("NGS" or the "Company") with the SEC on February 2,
2005, the Company entered into a senior secured loan agreement (the "Loan
Agreement") with Prospect Energy Corporation ("Prospect") providing for
borrowings by the Company of up to $4.8 million. The borrowings were secured by
substantially all of the Company's assets. The outstanding indebtedness bore
interest at an annual rate equal to the greater of (a) 14% and (b) the Treasury
Rate plus 9%, with interest payable in arrears on the last day of each month.
All outstanding indebtedness was to become due in full on February 2, 2010.
Pursuant to a number of amendments to the Loan Agreement, the total face amount
of borrowings at maturity drawn by the Company was $5.0 million.

On May 31, 2006, the Company voluntarily prepaid all amounts due under the Loan
Agreement totaling $5,437,352, representing the then-outstanding principal
balance of $5,000,000, all accrued and unpaid interest, a prepayment penalty and
certain other amounts due and owing under the Loan Agreement. The Company also
issued Prospect an additional five-year warrant to purchase up to 100,000 shares
of NGS common stock at an exercise price of $2.71 per share in satisfaction of a
disputed obligation relating to a voluntary waiver by Prospect of a technical
breach of a negative covenant by the Company. Concurrent with this repayment the
Loan Agreement was terminated and all of the collateral attached thereto was
released.

            The shares of common stock issuable upon exercise of the warrants
held by Prospect are subject to a registration rights agreement, pursuant to
which the Company has agreed to register sales by Prospect and its transferees
of such shares under the Securities Act of 1933, as amended. Subject to
limitations specified in this agreement, these registration rights include an
unlimited number of piggyback registration rights that require NGS to register
sales of a holder's shares when NGS undertakes a public offering.

            NGS issued and sold the foregoing securities pursuant to certain
exemptions from registration provided by Rule 506 of Regulation D and Section
4(2) and Section 4(6) of the Securities Act of 1933, as amended.


ITEM 3.01  UNREGISTERED SALES OF EQUITY SECURITIES

See Item 1.02 above.


Item 8.01 Other Events

As previously reported in a our Current Report on Form 8-K filed with the SEC on
May 11, 2006, NGS through our wholly-owned subsidiary NGS Sub Corp, entered into
a Purchase and Sale Agreement (the "Sale Agreement") on May 9, 2006 with Denbury
Onshore, LLC., a subsidiary of Denbury Resources, Inc., to conduct an enhanced
oil recovery project in the Company's Delhi Holt Bryant Unit within the Delhi
Field in northeast Louisiana. The closing of the Sale Agreement has been
extended from May 31, 2006 to June 6, 2006 and is subject to customary closing
conditions.
