      1. I have reviewed this quarterly report of NGAS Resources, Inc.

      2. Based on my knowledge, this report does not contain any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements made, in light of the circumstances under which they are made,
not misleading with respect to the period covered by this report.

financial information included in this report fairly present in all material
respects the financial condition, results of operations and cash flows of the
registrant as of the date and for the periods presented in this report.

      4. The registrant's other certifying officer and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rule 13a-15(e) and 15d-15(e)) for the registrant and internal
control over financial reporting (as defined in Exchange Act Rule 13a-15(f) and
15d-15(f)) for the registrant, and we have:

            (a) Designed such disclosure controls and procedures, or caused such
disclosure control and procedures to be designed under our supervision, to
ensure that material information relating to the registrant, including its
consolidated subsidiaries, is made known to us by others within those entities,
particularly within the period in which this report is being prepared;

            (b) Designed those internal controls over financial reporting, or
caused such internal controls over financial reporting to be designed under our
supervision, to provide reasonable assurances regarding the reliability of
financial reporting and the preparation of financial statements for external
purposes in accordance with generally accepted accounting principles;

            (c) Evaluated the effectiveness of the registrant's disclosure
controls and procedures and presented in this report our conclusions about the
effectiveness of the disclosure controls and procedures, as of the end of the
period covered by this report based on such evaluation; and

            (d) Disclosed in this report any change in the registrant's internal
control over financial reporting that occurred during the registrant's most
recent fiscal quarter that has materially affected or is reasonably likely to
materially affect the registrant's internal control over financial reporting.

      5. The registrant's other certifying officer and I have disclosed, based
on our most recent evaluation of internal control over financial reporting, to
the registrant's auditors and the audit committee of the registrant's board of
directors:

            (a) All significant deficiencies and material weaknesses in the
design or operation of internal controls over financial reporting which are
reasonably likely to adversely affect the registrant's ability to record,
process, summarize and report financial information; and

            (b) Any fraud, whether or not material, that involves management or
other employees who have a significant role in the registrant's internal control
over financial reporting.
