This Amendment No. 5 to 13G amends and restates in its entirety the Schedule 13G (as amended and restated, the “Schedule 13G”) filed on October 12, 2007, as amended by Amendment No. 1 filed on February 4, 2008, as further amended by Amendment No. 2 filed on January 15, 2009, Amendment No. 3 filed on January 20, 2009, and Amendment No. 4 filed on February 12, 2010, in each case filed by Titan Capital Management, LLC (“TCM”), TCMP3 Partners, L.P. (“TCM Partners”), Walter Schenker and Steven Slawson with respect to common stock, $0.01 par value per share (“Common Stock”) of Intrusion Inc. (“Issuer”). Walter Schenker as a co-managing member of TCM, the general partner of TCM Partners, shared voting and dispositive power over all of the shares of Common Stock of the Issuer owned of record by TCM and previously reported on the Schedule 13G (the “TCM Shares”). On July 1, 2010, in connection with the winding up and dissolution of TCM Partners, the TCM Shares were transferred to MAZ Partners LP. As a result, TCM Partners no longer owns any of the Issuer’s Common Stock and is no longer a reporting person and TCM is no longer deemed to beneficially own any of the Issuer’s Common Stock and is no longer a reporting person. MAZ Capital Advisors, LLC is the General Partner of MAZ Partners LP and Walter Schenker is the sole member and manager of MAZ Capital Advisors, LLC, therefore, Walter Schenker continues to exercise voting and dispositive control over the TCM Shares.
