Dear Mr. Maus:

      We have reviewed your filing and have the following

In some of our comments, we may ask you to provide us with
supplemental information so we may better understand your
disclosure.
After reviewing this information, we may or may not raise
additional
comments.

      Please understand that the purpose of our review process is
to
assist you in your compliance with the applicable disclosure
requirements and to enhance the overall disclosure in your filing.
We look forward to working with you in these respects.  We welcome
any questions you may have about our comments or on any other

Fee Table
1. We note the paragraph following the footnotes to the fee table
and
the debenture conversion event described in the fifth bullet point
on
page 23.  Please note that you may only register an indeterminate
number of additional securities that may become issuable pursuant
to
stock splits, stock dividends or similar transactions contemplated
by
Rule 416 of the Securities Act; Rule 416 does not permit you to
register an indeterminate number of additional shares that may be
issued upon conversion or exercise in the event that the company
subsequently issues securities at a price lower than the
applicable
conversion price of the debentures.  Please supplementally confirm
our understanding that in the event such an adjustment requires
you
to issue more shares than you are registering on this registration
statement, you will file a new registration statement to register
those additional shares.  Also, please revise this paragraph below
the fee table to track the language of Rule 416.

changes
in line items throughout the MD&A discussion.  Also, if more than

this
will impact revenues going forward.
22. Revise your discussion of gross profit/loss to quantify, to

converted and the debenture principal outstanding on February 19,
2004.
