Iliad Secured Convertible Promissory Notes Payable

On May 25, 2016 (the “Purchase Price Date”), the Company entered into a Securities Purchase Agreement (“Iliad SPA”) with Iliad Research and Trading, L.P. (the “Lender” or “Iliad”) pursuant to which the Lender loaned the Company $2,000,000. On the Purchase Price Date, the Company issued to Lender a Secured Convertible Promissory Note (the “Iliad Note”) in the principal amount of $2,055,000 in exchange for payment by Lender of $2,000,000. The principal sum of the Iliad Note reflects the amount invested, plus a 2.25% “Original Issue Discount” (“OID”) and a $10,000 reimbursement of Lender’s legal fees. Out of the proceeds from the Iliad Note, the Company paid the sum of $25,000 to its placement agent, Myers & Associates, L.P., which is a registered broker-dealer. The Company received net proceeds of $1,975,000 in exchange for the Iliad Note. The Iliad Note requires the repayment of all principal and any interest, fees, charges and late fees on the date that is thirteen months after the Purchase Price Date (the “Maturity Date”). Interest is to be paid on the outstanding balance at a rate of ten percent (10%) per annum from the Purchase Price Date until the Iliad Note is paid in full. Interest is accrued during the term of the Iliad Note and all interest calculations shall be computed on the basis of a 360-day year comprised of twelve (12) thirty (30)-day months and shall compound daily. Subject to adjustment as set forth in the Iliad Note, the conversion price for each Lender conversion shall be $0.50 (the “Lender Conversion Price”), convertible into shares of fully paid and non-assessable common stock. Beginning on the date that is six months after the Purchase Price Date and continuing until the Maturity Date, Iliad shall have the right to redeem a portion of the Iliad Note in any amount up to the Maximum Monthly Redemption Amount ($275,000, which is the maximum aggregate redemption amount that may be redeemed in any calendar month), for which payments may be made in cash or by converting the redemption amount into shares of Company common stock at a conversion price which is the lesser of (a) the Lender Conversion Price of $0.50 and (b) the Market Price, defined as 70% (“the Conversion Factor”), subject to adjustment as follows: if at any time (1) the average of the three lowest closing bid prices in the previous twenty (20) trading days is below $0.25 per share then the Conversion Factor will be reduced by 10%, (2) the Company is not Deposit/Withdrawal At Custodian eligible, then the Conversion Factor will be reduced by an additional 5%, or (3) there has occurred a “Major Default” then the Conversion Factor will be reduced by an additional 5%. The Company may prepay the Iliad Note at any time by payment to Lender of 125% of the principal, interest and other amounts then due under the Note. The Company may prepay the Iliad Note notwithstanding an earlier notice of conversion from the Lender, provided that in such event the Lender may convert an amount not to exceed $300,000 under the Iliad Note. In connection with the Iliad Note, as set forth above, the Company incurred an original issue discount of $45,000 and $35,000 of other debt issuance costs, which will be amortized over the Iliad Note term. The Iliad Note is securitized by the Company’s accounts receivable, inventory and equipment.

In November 2016, the Company entered into an Amendment to the Iliad Note (the “Iliad Amendment”), whereby the Lender and the Company agreed that the Maximum Monthly Redemption Amount for the period from November 2016 to January 2017 (the “Reduction Period”) be reduced from $275,000 to $166,667 (the “Reduced Maximum Monthly Redemption Amount”). In addition, if the Lender fails to convert the full Reduced Maximum Monthly Redemption Amount during any month in the Reduction Period, then any such unconverted amount shall increase the Reduced Maximum Monthly Redemption Amount in the following month or months. Furthermore, the Company shall not be allowed to pay any of the Reduced Maximum Monthly Reduction Amounts in cash. As such, all amounts converted must be converted into Redemption Conversion Shares of the Company’s common stock. Also, as part of the Iliad Amendment, the Lender agrees that, with respect to any Redemption Conversion Shares received during the Reduction Period, in any given calendar week its Net Sales of such Redemption Conversion Shares shall not exceed the greater of (a) 10% of the Company’s weekly dollar trading volume in such week or (b) $50,000 (the “Volume Limitation”). However, if the Lender’s Net Sales are less than the Volume Limitation for any given week, then in the following week or weeks, the Lender shall be allowed to sell an additional amount of Redemption Conversion Shares equal to the difference between the amount the Lender was allowed to sell and the amount the Lender actually sold. For the purpose of the Iliad Amendment, Net Sales is defined as the gross proceeds from sales of the Redemption Conversion Shares sold in a calendar week during the Reduction Period minus any trading commissions or costs associated with clearing and selling such Redemption Conversion Shares minus the purchase price paid for any shares of the Company’s common stock purchased in the open market during such week. The Lender and the Company both agree that in the event the Lender breaches the Volume Limitation where its Net Sales of Redemption Conversion Shares during any week during the Reduction Period exceeds the dollar volume the Lender is permitted to sell during such week pursuant to the Volume Limitation (the “Excess Sales”), then the Company’s sole and exclusive remedy for such breach shall be the reduction of the outstanding balance of the Iliad Note by an amount equal to 200% of the Excess Sales upon delivery of written notice to the Lender setting forth its basis for such reduction.

In January 2017, the Company entered into Amendment #2 to the Iliad Note (the “Iliad Amendment 2”). In accordance with the Iliad Amendment 2, during the period between January 27, 2017 and February 24, 2017, the Company agreed to allow the Lender to convert up to $500,000 (the “Additional Redemption Amount”) in Redemption Conversions under the Note, provided that the Lender shall not effectuate a Redemption Conversion of any Maximum Monthly Redemption Amount between January 27, 2017 and March 1, 2017. During this time period, the Company was not allowed to pay any of the Additional Redemption Amount in cash and all such amounts had to be converted into Redemption Conversion Shares of the Company’s common stock. In addition, the Lender agreed that the sale of any Redemption Conversion Shares between January 27, 2017 and April 30, 2017 (the “Limitation Period”) was subject to the Volume Limitation. Immediately following the expiration of the Volume Period, the Volume Limitation will be cancelled.

In March 2017, the Company entered into Amendment #3 to the Iliad Note (the “Iliad Amendment 3”). In accordance with the Iliad Amendment 3, during the period from March 1, 2017 to March 31, 2017, the Company agreed to allow the Lender to convert up to $500,000 (the “Additional Redemption Amount 2”) in Redemption Conversions under the Note, provided that the Lender not effectuate a Redemption Conversion of any Maximum Monthly Redemption Amount from March 1, 2017 until April 1, 2017. During this time period, the Company was not allowed to pay any of the Additional Redemption Amount 2 in cash and all such amounts had to be converted into Redemption Conversion Shares of the Company’s common stock. In addition, the Lender agreed that the sale of any Redemption Conversion Shares between March 1, 2017 and May 31, 2017 (the “Limitation Period 2”) shall be subject to the Volume Limitation. Immediately following the expiration of the Volume Period, the Volume Limitation will be cancelled.

In August 2017, the Company entered into Amendment #4 to the Iliad Note (the “Iliad Amendment 4”), whereby the Lender and the Company agreed to extend the Maturity Date of the Iliad Note to April 1, 2018. In addition, the parties agreed to amend the Volume Limitation in the Iliad Note, with respect to any Conversion Shares, such that in any given calendar week the Lender’s Net Sales of such Conversion Shares shall not exceed the greater of (a) 15% of the Company’s weekly dollar trading volume in such week or (b) $50,000 (the “Volume Limitation”). However, if the Lender’s Net Sales are less than the Volume Limitation for any given week, then in the following week or weeks, the Lender shall be allowed to sell an additional amount of Conversion Shares equal to the difference between the amount the Lender was allowed to sell and the amount the Lender actually sold. For the purpose of the Iliad Amendment 4, Net Sales is defined as the gross proceeds from sales of the Conversion Shares sold in a calendar week minus any trading commissions or costs associated with clearing and selling such Conversion Shares minus the purchase price paid for any shares of the Company’s common stock purchased in the open market during such week. The Lender and the Company both agree that in the event the Lender breaches the Volume Limitation where its Net Sales of Conversion Shares during any week exceeds the dollar volume the Lender is permitted to sell during such week pursuant to the Volume Limitation (the “Excess Sales”), then the Company’s sole and exclusive remedy for such breach shall be the reduction of the outstanding balance of the Iliad Note by an amount equal to 200% of the Excess Sales upon delivery of written notice to the Lender setting forth its basis for such reduction. In connection with the Iliad Amendment 4, Lender confirmed that no Events of Default or other material breaches exist under the Iliad Note and related Transaction Documents (as defined in the Iliad SPA).

During the year ended December 31, 2017, the Company issued 8,370,121 shares of its common stock to Iliad in connection with the conversions of the Iliad Note in the aggregate principal amount of $1,727,583 and $77,417 of accrued interest. The total of $1,805,000 was allocated to common stock and additional paid-in capital.

The Company’s borrowings and conversions under the Iliad SPA for the years ended December 31, 2017 and 2016 are summarized in the table below:

On the Purchase Price Date, the Company recorded a beneficial conversion feature of $370,000 (the “Iliad Instrument”), which was originally recorded in additional paid-in capital (“APIC”) and was scheduled for amortization over six months. The Company determined in 2016 that the Iliad Instrument qualifies for derivative accounting treatment. The $370,000 fair value of the Iliad Instrument at the Purchase Price Date is unchanged as a result of the change in derivative accounting treatment, however, in 2016 we reclassified the Iliad Instrument from APIC to a liability in accordance with derivative accounting treatment. During the year ended December 31, 2017, the Company recorded a gain of $222,800, for the change in fair value of the Iliad Instrument as part of a separate line item in the Company’s Consolidated Statement of Operations. The assumptions used by the Company for calculating the fair value of the Iliad Instrument at the Purchase Price Date using the Binomial Lattice valuation model were: (i) Volatility of 74.0%; (ii) Risk-Free Interest Rate of 0.44%; and (iii) Expected Term of five months; and as of December 31, 2017 were (i) Volatility of 61.0%, (ii) Risk-Free Interest Rate of 0.74%; and (iii) Expected Term of zero months.

In March 2017, the Company entered into another Securities Purchase Agreement (“Iliad SPA 2”) with Iliad pursuant to which the Lender loaned the Company $750,000. On March 1, 2017 (the “Subsequent Purchase Price Date”), the Company issued to Lender a Secured Convertible Promissory Note (the “Iliad Note 2”) in the principal amount of $770,000 in exchange for payment by Lender of $750,000. The principal sum of the Iliad Note reflects the amount invested, plus a $15,000 OID and a $5,000 reimbursement of Lender’s legal fees. The Company received net proceeds of $750,000 in exchange for the Iliad Note 2. The Iliad Note 2 requires the repayment of all principal and any interest, fees, charges and late fees on the date that is fourteen months after the Subsequent Purchase Price Date (the “Maturity Date”). Interest is to be paid on the outstanding balance at a rate of eight percent (8%) per annum from the Subsequent Purchase Price Date until the Iliad Note 2 is paid in full. Interest is accrued during the term of the Iliad Note 2 and all interest calculations shall be computed on the basis of a 360-day year comprised of twelve (12) thirty (30)-day months and shall compound daily. Subject to adjustment as set forth in the Iliad Note 2, the conversion price for each Lender conversion shall be the Lender Conversion Price, convertible into shares of fully paid and non-assessable common stock. Beginning on the date that is six months after the Subsequent Purchase Price Date and continuing until the Maturity Date, Iliad shall have the right to redeem a portion of the Iliad Note 2 in an amount not to exceed $100,000. Provided the Company has not suffered an “Event of Default” and is in compliance with certain “Equity Conditions” (unless waived by Iliad, in either case), the Company may make payments on such redemptions in cash or by converting the redemption amount into shares of Company common stock at a conversion price which is the lesser of (a) $0.50 per share and (b) 70% (“the Conversion Factor”) of the average of the three (3) lowest closing bid prices in the previous 20 trading days, subject to adjustment as follows: if at any time (1) the average of the three lowest closing bid prices in the previous twenty (20) trading days is below $0.25 per share then the Conversion Factor will be reduced by 10%, (2) the Company is not Deposit/Withdrawal At Custodian eligible, then the Conversion Factor will be reduced by 5%, (3) the Company is not DTC eligible, then the Conversion Factor will be reduced by an additional 5% or (4) there has occurred a “Major Default” then the Conversion Factor will be reduced by an additional 5% for each of the first three Major Defaults that occur after the effective date. The Company may prepay the Iliad Note 2 at any time by payment to Lender of 125% of the principal, interest and other amounts then due under the Note. The Company may prepay the Iliad Note notwithstanding an earlier notice of conversion from the Lender, provided that in such event the Lender may convert an amount not to exceed $200,000 under the Iliad Note 2. In connection with the Iliad Note 2, as set forth above, the Company incurred an original issue discount of $15,000 and $5,000 of other debt issuance costs, which will be amortized over the Iliad Note 2 term. The Iliad Note 2 is securitized by the Company’s accounts receivable, inventory and equipment.

The Company’s borrowings under the Iliad SPA 2 for the years ended December 31, 2017 and 2016 are summarized in the table below:

On the Subsequent Purchase Price Date, the Company recorded a derivative liability of $29,300 which is scheduled for amortization over 8 months. During the year ended December 31, 2017, the Company recorded a gain of $29,300, for the change in fair value of the derivative liability as part of a separate line item in the Company’s Consolidated Statement of Operations. The assumptions used by the Company for calculating the fair value of the derivative liability at the Subsequent Purchase Price Date and as of December 31, 2017 using the Binomial Lattice valuation model were: (i) Volatility of 85.0%; (ii) Risk-Free Interest Rate of 0.84%; and (iii) Expected Term of 8 months; and at December 31, 2017 were (i) Volatility of 84.0%, (ii) Risk-Free Interest Rate of 0.93%; and (iii) Expected Term of 4 months.
