Dear Mr. Harary:

      We have reviewed the above filings and have the following
accounting comments.  Our review has been limited to your
financial
statements and the related disclosures in Management`s Discussion
and
Analysis.  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 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
aspect
of our review.  Feel free to call us at the telephone numbers
listed
at the end of this letter.

Form 10-K for the year ended December 31, 2004

Note 9 - Shareholders` equity

1. We note your disclosure of the Class A and Class B warrants.
It
appears you received $10,000 cash in exchange for the issuance of
the
Class A and B warrants in 1998.  With regard to each class of
warrants, tell us how these warrants were valued, and how you have
accounted for this item in your financial statements.  Please
provide
the reference to the authoritative literature on which you relied
to
account for this item.

2. Tell us how many of each class of warrants are still
outstanding
as of December 31, 2004, and why these equity instruments are not
disclosed on the face of your December 31, 2004 balance sheet and
statement of stockholders` equity.

Closing Comments

      We urge all persons who are responsible for the accuracy and

provide, in writing, a statement from the company acknowledging
that:

the company is responsible for the adequacy and accuracy of the

proceeding initiated by the Commission or any person under the
federal securities laws of the United States.

	In addition, please be advised that the Division of
