1. I have reviewed this annual report on Form 10-K of American
Natural Energy Corporation;

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 such statements were made, not misleading
with respect to the period covered by this report;

3. Based on my knowledge, the consolidated financial
statements, and other financial information included in this report, fairly
present in all material respects the financial condition, results of operations
and cash flows of the small business issuer as of, and for, the periods
presented in this report;

4. The small business issuers other certifying officer(s) and
I are responsible for establishing and maintaining disclosure controls and
procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
small business issuer and have:

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

(b) Designed such
internal control over financial reporting, or caused such internal control over
financial reporting to be designed under our supervision, to provide reasonable
assurance 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 small business issuer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 small business issuers internal
control over financial reporting that occurred during the small business
issuers most recent fiscal quarter (the small business issuers fourth fiscal
quarter in the case of an annual report) that has materially affected, or is
reasonably likely to materially affect, the small business issuers internal
control over financial reporting; and

The small business issuers other
certifying officer(s) and I have disclosed, based on our most recent evaluation
of internal control over financial reporting, to the small business issuers
auditors and the audit committee of the small business issuers board of
directors (or persons performing the equivalent functions):

| | (a) | All significant deficiencies and material weaknesses in the
      design or operation of internal control over financial reporting which are
