Form 52-109F2 - Certification of Interim Filings


I, David Elsley, Chief Executive Officer, Vasogen Inc., certify that:

     1.   I have reviewed the interim filings (as this term is defined in
          Multilateral Instrument 52-109 Certification of Disclosure in Issuers'
          Annual and Interim Filings) of Vasogen Inc., (the issuer) for the
          interim period ended May 31, 2006;
     2.   Based on my knowledge, the interim filings do not contain any untrue
          statement of a material fact or omit to state a material fact required
          to be stated or that is necessary to make a statement not misleading
          in light of the circumstances under which it was made, with respect to
          the period covered by the interim filings;
     3.   Based on my knowledge, the interim financial statements together with
          the other financial information included in the interim filings fairly
          present in all material respects the financial condition, results of
          operations and cash flows of the issuer, as of the date and for the
          periods presented in the interim filings;
     4.   The issuer's other certifying officers and I are responsible for
          establishing and maintaining disclosure controls and procedures for
          the issuer, and we have designed such disclosure controls and
          procedures, or caused them to be designed under our supervision, to
          provide reasonable assurance that material information relating to the
          issuer, including its consolidated subsidiaries, is made known to us
          by others within those entities, particularly during the period in
          which the interim filings are being prepared.
