Additional Draw Request in connection with Loan Agreement with Prospect Energy
Corporation

      On March 16, 2005, Natural Gas Systems, Inc. ("NGS" or the "Company")
borrowed an additional $1.0 million (the "Additional Advance") under the terms
of the Loan Agreement (defined below) with Prospect Energy Corporation
("Prospect").

      On February 2, 2005, the Company entered into a senior secured loan
agreement (the "Loan Agreement") with Prospect providing for borrowings by the
Company of up to $4.8 million (the "Secured Loan"). The Loan Agreement was
finalized and first fundings made on February 3, 2005. The second funding,
namely the Additional Advance of $1.0 million on March 16, 2005, referenced in
this Current Report on Form 8-K, increased the total aggregate borrowings with
Prospect to $4.0 million. The Company has until May 4, 2005 to elect to borrow
the remaining $800,000 available under the Loan Agreement. The Secured Loan
bears 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. The Secured Loan is due in full on February 2, 2010. The proceeds of the
Secured Loan may be used solely for the acquisition and development of oil and
gas properties, general working capital and the repayment of specified
indebtedness, provided that the Company is prohibited from using any of the
proceeds for exploratory drilling or the acquisition of oil and gas properties
without the consent of Prospect.

      Pursuant to the terms of the Additional Advance under the Loan Agreement,
the Company was required to issue Prospect five-year warrants to purchase up to
150,000 shares of NGS stock at an exercise price of $0.75 per share, and
"revocable warrants" to purchase up to an additional 100,000 shares of common
stock at an exercise price of $0.75 per share. The revocable warrants are
subject to cancellation by the Company prior to their exercise if the Company
meets and maintains certain operating cash flow targets.

      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 and certain other types of
offerings, subject to the discretion of the managing underwriter of the
offering, if any, to decrease the amount that holders may register.
<PAGE>

      The Secured Loan is secured by a Mortgage, Collateral Assignment, Security
Agreement and Financing Statement executed by NGS Sub, Inc., a wholly owned
subsidiary of NGS ("NGS Sub"), granting Prospect a first-priority security
interest in substantially all of NGS Sub's assets, as well as by pledges of the
stock of NGS's direct and indirect subsidiaries. The Secured Loan is also
guaranteed by NGS's direct and indirect subsidiaries.

      Among other conditions, the Loan Agreement requires that the Company (i)
maintain a debt service reserve account in an initial amount equal to 7.5% (or,
after October 1, 2005, 5%) of the outstanding borrowings at any time (provided
that the required percentage shall be increased to 14% in the event certain
earnings tests are not met), and (ii) subject to certain conditions, obtain a
$1.5 million key-man life insurance policy on Robert S. Herlin, the Company's
President and Chief Executive Officer.

      Among other restrictions and subject to certain exceptions, the Loan
Agreement prohibits the Company and each of its restricted subsidiaries from
creating liens, entering into certain types of mergers or consolidations,
incurring additional indebtedness, changing the character of its business, or
engaging in certain types of transactions. The Loan Agreement also requires NGS
to maintain specified financial ratios. In order to satisfy certain of these
ratios, the Company will need to significantly increase its earnings.

      The Loan Agreement provides that the Company will be in default under the
Secured Loan if Mr. Herlin shall cease for any reason to be actively employed
full time as President of NGS, unless NGS replaces Mr. Herlin within 90 days
following such event, and his replacement is reasonably satisfactory to
Prospect.
