Exhibit
31.1
CERTIFICATION
I,
Marvin S. Hausman, certify that:
1. I
have reviewed this quarterly report on
Form 10-QSB of OXIS International, Inc. (“registrant”);
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 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
registrant as of, and for, the periods presented in this report;
4. The
registrant’s other certifying officers and I are
responsible for establishing and maintaining disclosure controls and procedures
(as defined in Exchange Act Rules 13a, 15(e) and 15-d-15(e)) and internal
control over financial reporting (as defined in Exchange Act Rules 13a-15(f)
and
15d-15(f)) for the registrant 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 registrant, 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 principals;
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 (the registrant’s fourth fiscal quarter in the case
of an annual report) that has materially affected, or is reasonably likely
to
materially affect, the registrant’s internal control over financial reporting;
and
5. The
registrant’s other certifying officer(s) 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 (or persons performing the equivalent
functions):
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 data 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
controls.
