value (the "Shares") to be issued and sold pursuant to the Micro Magic 1995
Stock Option Plan and the Micro Magic 2000 Stock Option Plan (collectively, the
"Plans"), I am of the opinion that:
1. The Plans have been duly adopted by the Company.
2. All proper corporate proceedings have been taken so that the

therefore in accordance with the Plans and the resolutions of the
board of directors of the Company relating to the adoption of the
Plans and the offering and sale of the Shares thereunder, will be
legally issued, fully paid and nonassessable.
I hereby consent to the filing of this opinion with the Securities and
Exchange Commission in connection with the registration statement referred to

federal law of the United States of America.
Very truly yours,
