Subsequent Events On July 1, 2016, the Company and Lincoln Park entered into the Lincoln Park Termination Agreement, terminating the Purchase Agreement and a separate registration rights agreement effective July 1, 2016, as more fully set forth in the Termination Agreement. Under the Lincoln Park Termination Agreement, certain provisions of the Purchase Agreement survive the termination of the Purchase Agreement for a limited period, including certain covenants in the Purchase Agreement prohibiting the Company from entering into certain non-exempt variable rate transactions (the “Variable Rate Covenants”). Lincoln Park has also waived the application of the Variable Rate Covenants to certain previous issuances of securities by the Company. The Company and Lincoln Park have also agreed to mutually release each other from any and all claims under the Transaction Documents, except for certain surviving obligations set forth in the Termination Agreement. The Company agreed to issue to Lincoln Park warrants to purchase up to 100,000 shares of the Company’s common stock, which warrants are immediately exercisable at an exercise price of $6.00 per share for five years from July 1, 2016. On July 7, 2016, the Company entered into an amendment #3 to borrowing agreement with Mr. Hanson in connection with a revolving line of credit note entered into by the parties on May 7, 2014 (as subsequently amended). Pursuant to that amendment, which is effective as of June 30, 2016, the parties agreed that the Company make interest-only payments on January 31, 2017 and not on June 30, September 30 and December 31, 2016 as previously agreed upon by the parties. On July 7, 2016, the Company entered into an addendum #4 to commitment letter with Mr. Hanson in connection with a commitment letter entered into by the parties on July 30, 2014 (as subsequently amended). Pursuant to that addendum, which is effective as of June 30, 2016, the parties extended the payment date of the interest-only payments that were or will be due and payable on June 30, September 30 and December 31, 2016 to January 31, 2017. On July 13, 2016, the Subsidiary entered into an addendum #1 to demand promissory note with Mr. Hanson in connection with a demand promissory note issued by the Subsidiary to Mr. Hanson on December 22, 2015. Pursuant to that addendum, which is effective as of June 30, 2016, the parties extended the maturity date under the demand promissory note from June 30, 2016 to January 31, 2017. On July 13, 2016 (the “Davis Issuance Date”), the Company issued to Mr. Davis a convertible promissory note in the principal amount of $360,000 and a warrant to purchase up to 20,000 shares of the Company’s common stock, subject to adjustments, in exchange for an aggregate purchase price of $300,000, payable by Mr. Davis within three business days after the issuance of the note. The warrant has an exercise price of $6.00 per share, subject to adjustments, and is exercisable for a five year period. The note does not bear any interest, other than during an event of default (in which case default interest at a rate of 24% per annum is applicable). The note is due and payable six months after the Davis Issuance Date. In addition to the Company providing three days advance written notice to an investor prior to repayment, under the terms of the note upon repayment of the note (including on the maturity date) the Company is obligated to pay a 20% premium on the principal amount and any accrued default interest then due on the note, which in the aggregate is equal to 120% of the principal amount and any accrued default interest then due on the note. The holder cannot convert the note during such three day advance notice period prior to repayment unless an event of default has occurred under the note and at least six months and three days have elapsed since the issuance date of the note. Under the terms of the note, among other events, an event of default will occur if the Company fails to repay the note in its entirety at 120% of the principal amount and any then accrued default interest with the proceeds received from the Company’s next underwritten offering of $5,000,000 or more that is completed on or after the Issuance Date. If an event of default occurs under the note and to the extent the Company has a three calendar day cure period for such event of default under the note, the Company fails to cure such default within three days, at the holder’s election, the note shall accelerate and become immediately due and payable in full in cash at the mandatory default amount, which is equal to 120% multiplied by the total amount outstanding under the note, and thereafter interest on the note shall accrue at the lesser of 24% per annum and the maximum rate permitted under applicable law. If an event of default occurs under the note, the holder may elect to convert the note into shares of common stock at any time following six months and three days after the Issuance Date, and the conversion price per share is equal to 60% of the lowest volume weighted average price of the Company’s common stock during the 21 consecutive trading days immediately preceding the conversion date. The convertible note and the warrant were issued to Mr. Davis in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act. On July 14, 2016 (the “Hanson Issuance Date”), the Company issued to Mr. Hanson a convertible promissory note in the principal amount of $240,000 and a warrant to purchase up to 13,334 shares of the Company’s common stock, subject to adjustments, in exchange for an aggregate purchase price of $200,000, payable by Mr. Hanson within three business days after the issuance of the note. The warrant has an exercise price of $6.00 per share, subject to adjustments, and is exercisable for a five year period. The note does not bear any interest, other than during an event of default (in which case default interest at a rate of 24% per annum is applicable). The note is due and payable six months after July 14, 2016. In addition to the Company providing three days advance written notice to an investor prior to repayment, under the terms of the note upon repayment of the note (including on the maturity date) the Company is obligated to pay a 20% premium on the principal amount and any accrued default interest then due on the note, which in the aggregate is equal to 120% of the principal amount and any accrued default interest then due on the note. The holder cannot convert the note during such three day advance notice period prior to repayment unless an event of default has occurred under the note and at least six months and three days have elapsed since the issuance date of the note.

If an event of default occurs under the note and to the extent the Company has a three calendar day cure period for such event of default under the note, the Company fails to cure such default within three days, at the holder’s election, the note shall accelerate and become immediately due and payable in full in cash at the mandatory default amount, which is equal to 120% multiplied by the total amount outstanding under the note, and thereafter interest on the note shall accrue at the lesser of 24% per annum and the maximum rate permitted under applicable law. If an event of default occurs under the note, the holder may elect to convert the note into shares of common stock at any time following six months and three days after the Hanson Issuance Date and the conversion price per share is equal to 60% of the lowest volume weighted average price of the Company’s common stock during the 21 consecutive trading days immediately preceding the conversion date. The convertible note and the warrant were issued to Mr. Hanson in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act. On July 21, 2016, the Company filed a registration statement on Form S-1 (File No. 333-212610) in which it proposes to offer to the public shares of its common stock, $0.0001 par value per share, at a proposed maximum of $20.0 million in shares.

The notes and the warrants were issued in reliance on the exemption from registration provided by the Securities Act and Rule 506 of Regulation D thereunder. The notes are unsecured, do not bear any interest and are payable in full on August 11, 2017. Columbus Capital may elect to convert the principal amount of the notes into shares of the Company’s common stock at any time before August 11, 2017 at a conversion price per share equal to the lower of $5.55 and 80% of the per share sale price of the Company’s common stock in the Company’s next underwritten public offering. The Company has the right to require Columbus Capital to convert the notes into shares of the Company’s common stock at that conversion price if the Company’s common stock is listed on the Nasdaq Capital Market, the Nasdaq Global Market or the Nasdaq Global Select Market. The warrants issued to Columbus Capital have an exercise price of $5.55 per share, subject to adjustments, and are exercisable for a five year period. In addition, under the securities purchase agreement with Columbus Capital, the Company is required to file with the Securities and Exchange Commission a registration statement covering the resale of the shares of the Company’s common stock issuable under the notes and the warrants within 21 days following the consummation of the Company’s next underwritten public offering or 90 days following the date on which the Company’s current financing plan is terminated.
