quarterly report on Form 10-Q of Health Discovery Corporation (the
“Registrant”);





2.  Based on my knowledge,
this quarterly 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 quarterly report;





3.  Based on my knowledge,
the financial statements, and other financial information included in this
quarterly 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 quarterly 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 internal controls over financial reporting (as defined in Exchange Act Rules
13a-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
controls over financial reporting, or caused such internal controls 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;

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 first fiscal quarter in the case of this report) 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 officers 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 Registrant’s board of directors (or persons performing the
equivalent functions):





a)  all significant
deficiencies in the design or operation of internal control 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.
