Audit Fees (1)	$	170,060	$	158,428

________________

(1) Consists of fees for professional services rendered in connection with the audit of the Company's financial statements for the fiscal years ended June 30, 2006 and June 30, 2005; the reviews of the financial statements included in each of the Company's quarterly reports on Form 10-Q during those fiscal years; and consents and assistance with documents filed by the Company with the SEC.

(2) Consists of fees for tax advisory services in connection with preparation of the Company's federal and state tax returns and I.R.S. audit.

The Audit Committee of the Board of Directors of the Company considered that the provision of the services and the payment of the fees described above are compatible with maintaining the independence of BDO Seidman, LLP.

The Audit Committee is responsible for reviewing and pre-approving any non-audit services to be performed by the Company's independent auditors. The Audit Committee has delegated certain of its pre-approval authority to the Chairman of the Audit Committee to act between meetings of the Audit Committee. Any pre-approval given by the Chairman of the Audit Committee pursuant to this delegation is presented to the full Audit Committee at its next regularly scheduled meeting. The Audit Committee or Chairman of the Audit Committee reviews and, if appropriate, approves non-audit service engagements, taking into account the proposed scope of the non-audit services, the proposed fees for the non-audit services, whether the non-audit services are permissible under applicable law or regulation and the likely impact of the non-audit services on the independence of the independent auditors.

Since the effective date of the SEC rules requiring pre-approval of non-audit services on May 6, 2003, each new engagement of the Company's independent auditors to perform non-audit services has been approved in advance by the Audit Committee or the Chairman of the Audit Committee pursuant to the foregoing procedures.
