                SUPPLEMENT TO PROSPECTUS DATED NOVEMBER 15, 2004

Our shares have been authorized for quotation on the OTC Bulletin Board.

In December 2004 we granted an option for the purchase of 150,000 shares to each
of Messrs. Bakeman and Westerholm under our 2001 Employee Incentive Stock Option
Plan exercisable at  $1.22 and $1.35 per share, respectively.  One-third of the
option amount of shares became immediately exercisable when the options were
granted.  An additional one-third may be acquired on or after December 6, 2005
and the remaining shares may acquired on and after December 6, 2006.  Mr.
Bakeman's option expires on December 5, 2014 and Mr. Westerholm's option expires
on December 5, 2009.

The annual salaries of Messrs. Bakeman and Westerholm have been increased to
$200,000 and $225,000, respectively.

We intend to hire Donald C. Harms as our general counsel prior to April 2005
pursuant to a proposed three-year contract under which he will receive an annual
base salary of $175,000.  The other terms of the contract will be substantially
the same as those of the contracts with our three executive officers.  Upon Mr.
Harms' employment, he will also receive an option for the purchase of 150,000
shares similar to the option granted to Mr. Bakeman as described above.  The per
share exercise price of Mr. Harms' option will be the market value of our
shares on the day that Mr. Harms' employment begins.

Beginning in December 2004, we will compensate each of the independent members
of our Board of Directors at the annual rate of $10,000 to accrue and to be paid
when the Board of Directors determines that there are sufficient funds.
