(1) Dividends accrue on our outstanding Series A preferred stock at the rate of $0.20 per annum per share of Series A preferred stock. We have not paid any dividends on preferred stock.  883,000 shares of our preferred stock were issued and outstanding for all of the periods presented.

(2) Represents one-third of total rent expense which we believe is a reasonable estimate of the interest component of rent expense. Interest component of rental expense is estimated based on interest on tenant improvement loan at 4%, which is considered a reasonable approximation of the interest factor. In 2010, the full amount of the tenant improvement was paid off.

(3) For periods in which there is a deficiency of earnings available to cover combined fixed charges and preferred stock dividends, the ratio information is not applicable.
