[1] - Convertible Preferred Stock would potentially be considered a participating security under the two-class method of calculating net loss per share. However, the Company has incurred net losses to-date, and as such holders are not contractually obligated to share in the losses, there is no impact on the Company’s net loss per share calculation for the periods indicated.
