Total earnings were insufficient to cover the fixed charges for the six months ending July 3, 2009 by $14.3 million primarily due to operating losses. Accordingly, such ratio is not presented for such period.

Fixed charges are equal to interest expense (including amortization of deferred financing costs), plus the portion of rent expense estimated to represent interest.
