[1] The net loss used for the computation of basic and diluted net loss per share for the year ended December 31, 2018, includes the preferred dividend requirement of 8% per share per annum for the Series B Preferred Stock, for the portion of the year during which these securities were issued and outstanding, compounded annually which shall be distributed to stockholders in case of distributable assets determined in the Company's certificate of designation under the liquidation preference right (see also Note 10).

[2] Based on the rights and privileges of Series B Preferred Stock, since the Company did not obtain shareholder approval at March 31, 2018, the then outstanding Series B Preferred Stock became redeemable at the option of OFI. Consequently, in each reporting period commencing March 31, 2018, the outstanding Series B Preferred Stock is recorded at its maximum redemption value until occurrence of redemption or conversion. These shares were cancelled as a result of the entry into the Remediation Agreement on September 24, 2018 as described below (see also Note 10).
