Dear Mr. Shah:

      We have reviewed your response letter and have the following
comments.  We have limited our review of your filing to those
issues
we have addressed in our comments.  Where indicated, we think you
should revise your document in response to these comments.  If you
disagree, we will consider your explanation as to why our comment
is
inapplicable or a revision is unnecessary.  Please be as detailed
as
necessary in your explanation.  In some of our comments, we may
ask
you to provide us with information so we may better understand
your
disclosure.  After reviewing this information, we may raise
additional comments.

Form 20-F for the Fiscal Year Ended March 31, 2004

Consolidated Financial Statements

Consolidated Statements of Cash Flows, page F-6

1. We have considered your response to prior comment three and do
not
find your argument persuasive in light of the guidance in CICA
1100.31, which indicates that industry practice does not
necessarily
equate to the primary sources of GAAP.  We reissue prior comment
three.


Note 2 - Significant Accounting Policies, page F-9

Stock-Based Compensation Plan, page F-11

2. Please provide a sample of your intended disclosure revision
with
respect to prior comment four.

Note 3 - Prepaid and Other Receivables, page F-11

3. We have reviewed your response to prior comment five and note
your
indication that the balance Due from director, totaling $20,000 as
of
March 31, 2004, has been paid in full as of March 31, 2005.
Please
provide the terms of the original loan and confirm, if true, (i)
that
a loan document exists between the Company and the director and
(ii)
that the loan agreement has been filed as an exhibit under Item 19
of
Form 20-F (refer to 4.(b)(i) under the Instructions As To
Exhibits).

In addition, please provide an analysis of the terms of the loan
as
compared to those available from an independent third party.  To
the
extent the loan terms are preferential, please disclose a
corresponding quantitative entry in the Summary Compensation Table
on
page 26.  Similarly, loans to directors would also need to be
fully
discussed as part of the compensation received by directors and
senior management under Item 6.B.1. of Form 20-F.
