Dear Mr. Flagg:

		We have reviewed your response letter dated June 28,
2005
and have the following additional comments.  If you disagree with
a
comment, 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.

	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-Q for the Quarter Ended March 31, 2005

Consolidated Statements of Cash Flows, page 7
1. We have reviewed your response to comment one.  Please tell us
why
you have revised the operating cash flow provided by the change in
accounts payable from $1,575,787 in your originally filed Form 10-
Q
to $544,614 in the amended Form 10-Q.  Please provide us with a
reconciliation of the change during the six months to the reported
amounts.  Tell us whether you have broken out the non-cash portion
of
accounts payable elsewhere in the reconciliation.  If not, please
cite the specific section of the relevant accounting literature
supporting your exclusion of a portion of accounts payable from
the
period-to-period change or revise your statement of cash flows
accordingly.
2. Please revise your amended Form 10-Q to label the statement of
cash flows as restated and to include an explanatory note
describing
the restatement and the nature of the errors.  Please refer to
paragraphs 13, 36 & 37 of APB 20 for the correction of an error in
previously issued financial statements.
3. We have reviewed your response to comment two.  The detail of
the
Deposits and other assets line item you provided to us indicates
you
may have presented non-cash interest expense and other non-cash
expenses as investing cash flows.  Please note that the objective
of
SFAS 95 is to reflect cash flows by classifying cash receipts and
payments based on whether they stem from operating, investing or
financings activities.  Expenses without an associated cash flow
are
generally reflected as reconciling items in the reconciliation of
net
income to operating cash flow.  Please provide us with additional
information to help us understand the appropriateness of your
presentation.
4. It also appears that you have reflected debt issue costs in
Deposits and other assets in 2003 and 2002.  Please note that EITF
95-13 requires that such costs be reflected as financing cash
flows.
Please advise or revise.
