Form 8-K previously filed by Ampex Corporation (the &#147;Company&#148;) on February 23, 2005, the Audit Committee of the Company&#146;s Board of Directors has concluded that the previously issued financial statements contained in the Company&#146;s
Annual Report on Form 10-K as of December 31, 2003 and December 31, 2002 and for each of the years in the period ended December 31, 2003, as well as its interim financial statements contained in Form 10-Q as of and for the periods ending March 31,
2004, June 30, 2004 and September 30, 2004, should no longer be relied upon because of errors in those financial statements. These errors relate to how the Company accounted for its obligations under a pension plan of its former magnetic tape

due to the substantial amount of additional work associated with the restatements, despite diligent efforts. The Company currently expects to file the restated financial reports on Form 10-K for 2003, the interim financial statements included in

year ended December 31, 2004. The Company announced that income from continuing operations, on a preliminary unaudited basis, totaled $48.5 million or $12.73 per diluted share up from a preliminary restated loss from continuing operations in 2003 of
$1.8 million or $0.53 per diluted share. The loss for 2003 included a restructuring provision of $3.1 million related to previously vacated real estate. The significant increase in net income was due primarily to an increase in licensing revenues
from having concluded new license agreements with several manufacturers of digital still cameras, digital video camcorders and DVD recorders. A portion of royalties received in 2004 relates to non-refundable, non-forfeitable prepayments by certain
licensees of their obligations through April 2006. </FONT></P> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT SIZE="1">&nbsp;</FONT></P><HR SIZE="1" NOSHADE COLOR="#000000" ALIGN="left"> <P STYLE="margin-top:0px;margin-bottom:0px"><FONT
