     I have reviewed this Quarterly Report on Form 10-Q of
Omnimmune for the period ended September 30, 2009;
 
 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

 4.
     Omnimmune’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)) and internal control
over financial reporting (as defined in Exchange Act Rules 13a-15(f) and
15d-15(f)) for Omnimmune 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 Omnimmune,
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

principles;

     Disclosed in this report any change
in  Omnimmune’s internal control over financial reporting that

quarter in the case of an annual report) that has materially affected, or is
reasonably likely to materially affect, Omnimmune’s internal control over
financial reporting; and
 
 5.
     Omnimmune’s other certifying officer(s) and I have

financial reporting, to Omnimmune’s auditors and the 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
reasonably likely to adversely affect Omnimmune’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 Omnimmune’s
internal control over financial reporting.
