Description of subscription agreement with certain investors |  | Pursuant to which the Company, in a private placement (the "Private Placement"), agreed to issue and sell to the Subscribers 8% convertible promissory notes (the "2017 Convertible Notes") and warrants (the "New Warrants") to purchase shares of the Company's capital stock in the event of a conversion event. The number of shares and pricing per share of the New Warrants are based on the underlying conversion event and are exercisable for five years commencing on the triggering conversion event. The subscription agreement, the 2017 Convertible Notes and New Warrants were amended on December 14, 2017 to move up the maturity date of the 2017 Convertible Notes from October 4, 2022 to December 31, 2018, remove subordination provisions and simplify the conversion provision of the 2017 Convertible Notes in the event of a qualified financing as described more fully below, to modify the exercise price of the New Warrants and to increase the authorized subscription amount to $1,500,000. In May 2018, the Board approved an increase in the authorized subscription amount from $1,500,000 to $2,000,000 and extended the offering period from the five month anniversary of the initial closing to the eight month anniversary of the initial closing. The initial closing of the Private Placement was consummated on October 4, 2017, and the Company entered into additional subscription agreements and issued 2017 Convertible Notes in an aggregate principal amount of $1,540,000 to the Subscribers through June 2018 when the Private Placement expired. |  |  |  |  |
Description of convertible notes issuance costs |  | Prior to the December 2017 amendment, if the Company had raised more than $3,000,000 in an equity financing before October 4, 2022, the outstanding principal and accrued and unpaid interest on the 2017 Convertible Notes would have automatically converted into the securities issued by the Company in such financing based on the greater number of such securities resulting from either (i) the outstanding principal and accrued interest on the 2017 Convertible Notes divided by $2.25 or (ii) the outstanding principal and accrued interest on the 2017 Convertible Notes multiplied by 1.25, divided by the price paid per security in such financing. The New Warrants would have also become exercisable in conjunction with the 2017 Convertible Notes Qualified Financing. |  |  |  |  |

If the Company consummates an equity round of financing resulting in more than $3 million in gross proceeds before December 31, 2018 (the "2017 Convertible Notes Qualified Financing"), the outstanding principal and accrued and unpaid interest on the 2017 Convertible Notes shall automatically convert into the securities issued by the Company in the 2017 Convertible Notes Qualified Financing equal to the outstanding principal and accrued interest on the 2017 Convertible Notes divided by 80% of the price per share of the securities issued by the Company in the 2017 Convertible Notes Qualified Financing. |  |  |
