| (1) | One third of rent expense was included in the calculation as it is a reasonable approximation of the interest factor. |
| (2) | We did not record earnings for the six months ended June 30, 2015 and for the years ended December 31, 2014, 2013 and 2012. Accordingly, our earnings were insufficient to cover fixed charges for such periods, and we are unable to disclose a ratio of earnings to fixed charges for such periods. |
| (3) | Preferred stock dividends relate to the accretion of convertible preferred stock to redemption value. We accrete preferred stock to redemption value in full in the reporting period the charge occurs. |
| (4) | We did not record earnings for the six months ended June 30, 2015 and for the years ended December 31, 2014, 2013 and 2012. Accordingly, our earnings were insufficient to cover fixed charges and preferred stock dividends for such periods, and we are unable to disclose a ratio of earnings to combined fixed charges and preferred stock dividends for such periods. |
