COMPUTATION OF RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth our ratio of earnings to fixed charges for each of the periods indicated.  To date we have not issued any preferred stock.  Therefore, the ratio of earnings to combined fixed charges and preferred stock dividend requirements are the same as the ratio of earnings to fixed charges presented below.

	Fiscal Year Ended														Six Months Ended
	December 31, 2004			January 1, 2006		December 31, 2006			December 30, 2007			December 28, 2008			June 28,2009
Income (loss) before income taxes	$	(8,832	)	$	2,519	$	(9,143	)	$	(11,059	)	$	(9,409	)	$	(4,834	)
Add: Fixed charges(1):
Interest expensed	255			189		329			280			255			47
Interest on rental expenses	306			320		283			293			211			97
Total — fixed charges	561			509		612			573			436			144
Total earnings (loss) for computation of ratio	(8,271		)	3,028		(8,531		)	(10,486		)	(8,973		)	(4,690		)
Ratio of earnings to fixed charges(2)	—			5.95		—			—			—			—

(1)Fixed charges include interest expense plus the portion of interest expense under operating leases deemed by us to be representative of the interest factor.

(2)Due to our losses in the years ended December 31, 2004, January 1, 2006, December 31, 2006, December 30, 2007 and December 28, 2008 and the six months ended June 28, 2009, the ratio coverage was less than 1:1.  Additional earnings of $8.8 million, $9.1 million, $11.0 million, $9.4 million and $4.8 million for the years ended December 31, 2004, January 1, 2006, December 31, 2006, December 30, 2007 and December 28, 2008 and the six months ended June 28, 2009, respectively, would have been required to achieve a ratio of 1:1.
