Item 8.01 Other Events

      After the close of business on October 26, 2005, the Company learned that
a lawsuit has been filed against the Company and six of its eight directors by
Ahmed Hussein, a director and significant shareholder of the Company. The
complaint names the Company and individual directors, Patrick Cline, Maurice
DeWald, Vincent Love, Steven Plochocki, Sheldon Razin and Louis Silverman.
Director Ibrahim Fawzy was not named as a defendant.

      Filed in the Superior Court for Orange County, California, the complaint
alleges that in connection with the Company's 2005 Annual Shareholders' Meeting,
the certified results from the independent inspector of election included
certain proxies that should not have been included in the final vote tabulation.
The independent inspector of election has certified the election of the
Company's eight directors (as previously announced) after hearing Mr. Hussein's
claim concerning this matter.

      The Company believes that Mr. Hussein's claims lack merit and that the
results certified by the independent inspector of elections are conclusive of
this matter. The Company intends to defend itself vigorously.

      Statements made in this report that state the Company's intentions, hopes,
beliefs, expectations or predictions of the future, may constitute
"forward-looking statements" within the meaning of Section 21E of the Securities
and Exchange Act of 1934, as amended (the "Exchange Act"). Forward-looking
statements are not guarantees of future performance or results. They involve
risks, uncertainties and assumptions. It is important to note that any such
actual results could differ materially from those expressed in such
forward-looking statements and the Company does not undertake to update its
views concerning such.
