Item 7. Management’s Discussion and Analysis

Results of Operations — Segments, page 15

2. We note your response to prior comment 4. Given that the corrections result in an approximately 11% decrease in your net loss for the year ended June 30, 2005 and a 15% decrease in net loss for the quarter ended December 31, 2004, it is unclear how you determined that the corrections were not material to past-presented financial information, trends in earnings, or to the most current projected results for the current fiscal year. Please file an amendment to your Form 10-K to revise your financial statements or explain to us in greater detail why these amounts are not quantitatively material. In addition, we do not understand why you did not record the catch-up adjustment in the quarter ended September 30, 2004, which would have been the beginning of your fiscal year, if you believed the amounts were immaterial. Had you done this, it appears that the significance of the correction would be even greater in that quarter. We remind you of the requirements of Item 4.02(a) of Form 8-K. We also remind you that if you file your restated Form 10-K you should appropriately address the following:

• An explanatory paragraph in the reissued audit opinion,

• full compliance with APB 20, paragraphs 36 and 37,

• fully update all affected portions of the document, including MD&A, selected financial data, and quarterly financial data, and

• updated certifications.

The Company is providing you with the following additional explanation why we believe the amounts were not quantitatively material.

The Company discovered in its second quarter of fiscal year 2005 (the quarter ended December 31, 2004) that an error in the application of an accounting principle had occurred and that the error potentially impacted previously issued financial statements. The Company determined the impact of the error was immaterial to the previously issued financial statements and recorded a catch-up adjustment in the second quarter of fiscal year 2005. The catch-up adjustment was not recorded in the quarter ended September 30, 2004 as the error was not detected until the quarter ended December 31, 2004. In determining the impact of the catch-up adjustment on the quarter ended December 31, 2004, the Company considered, as required by APB Opinion 28, the impact of the misstatement on the projected full fiscal year ending June 30, 2005 and the trend of earnings, and determined the impact not to be material.

The Company followed SAB Topics 1:M and 5:F in evaluating the materiality of the error and in determining that prior periods did not need to be restated.

SAB Topic 1:M notes that exclusive reliance on any percentage or numerical threshold has no basis in the accounting literature or the law. A matter is “material” if there is a substantial likelihood that a reasonable person would consider it important. An assessment of materiality requires that the Company views the facts in the context of the “surrounding circumstances” that is, the Company must consider both quantitative and qualitative factors in assessing an item’s materiality. The dollar amounts of the error and the catch-up adjustment were small, $68,000 being the largest impact in any period, and as such immaterial when addressed singularly. That is, there was not a substantial likelihood, in our opinion, that a reasonable person would consider it important. Other factors to consider are as follows:

• The Company’s trend of revenues, gross profit and net income (loss) was not impacted by the misstatement.

• The misstatement did not change a loss into income or vice versa.

• The Company did not in the past and does not currently have analysts’ coverage. The Company’s stock was in the past and is currently thinly traded, averaging approximately 2,995 shares daily with approximately 3,000,000 outstanding shares. In determining the impact of the misstatement on actual results for the fiscal year ended June 30, 2005, the Company noted that it had substantial profitability in the past, net income from continuing operations was $2,402,000, $911,000, $6,079,000, and $4,257,000 for the fiscal years ended June 30, 2004, 2003, 2002, and 2001, respectively. However, for the fiscal year ended June 30, 2005 the Company recorded a net loss from continuing operations of $526,000, an amount closer to breakeven and as such other items on the income statement such as revenues and gross profits were considered in determining materiality.

• Neither segment has a more significant role in the Company’s long-term operations or profitability.

• The misstatement did not affect the Company’s compliance with regulatory requirements, loan covenants or other contractual requirements.

• The misstatement did not have the effect of increasing management’s compensation.

• The misstatement did not involve concealment of an unlawful transaction.
