	As noted in our prior letter, we urge all persons who are
responsible for the accuracy and adequacy of the disclosure in the
filing reviewed by the staff to be certain that they have provided
all information investors require for an informed decision.  Since
the company and its management are in possession of all facts
relating to a company`s disclosure, they are responsible for the
accuracy and adequacy of the disclosures they have made.

	In connection with responding to our comments, please
provide,
in writing, a statement from the company acknowledging that:

* the company is responsible for the adequacy and accuracy of the
disclosure in the filing;

* staff comments or changes to disclosure in response to staff
comments do not foreclose the Commission from taking any action
with
respect to the filing; and

* the company may not assert staff comments as a defense in any
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
Enforcement
has access to all information you provide to the staff of the
Division of Corporation Finance in our review of your filing or in
