Terms of the Notes

The Notes provide for distribution of the proceeds held pursuant to the Control Agreement as follows:

The amount released pursuant to the Notes and the Control Agreement on each of these dates will be reduced to an amount equal to the lesser of the value of the shares of Common Stock (i) covered by an effective resale registration statement, (ii) the Note holders are eligible to resell under Securities Act Rule 144, or (iii) eligible for issuance under the Nasdaq Rules without shareholder approval (which limitation is eliminated after the Company has obtained such shareholder approval), if applicable, based on the conversion formula in the Notes.

All amounts outstanding under the Notes mature and are due and payable on or before April 1, 2019. Prior to maturity, the Notes bear interest at 8% per annum (or 18% per annum during an event of default) with interest payable monthly in arrears on the Installment Dates (as defined below) and on conversion dates.

On the last business day of each month, commencing on July 29, 2016 (each, an “Installment Date”), the Company is obligated to pay the holders of the Notes a total amount equal to (i) $312,500 (1/32nd of the original principal amount of the Notes) or the principal outstanding on the Installment Date, if less, plus (ii) the accrued and unpaid interest with respect to such principal, plus (iii) the accrued and unpaid late charges (if any) with respect to such principal and interest, and plus (iv) any amount deferred or accelerated by a Note holder, as discussed below. Each Installment Date payment may be made in cash, in shares of Common Stock, or in a combination of cash and shares of Common Stock. The Company’s ability to make such payments with shares of Common Stock will be subject to satisfaction of various equity conditions during a 20 trading day-period before the applicable date of determination (the “Measurement Period”), including the existence of an effective registration statement covering the resale of the shares issued in payment (or, in the alternative, the eligibility of the shares issuable pursuant to the Notes for resale without restriction under Securities Act Rule 144), continued listing on the Nasdaq Capital Market, and a certain minimum trading volume and minimum trading price of the Common Stock. If making an Installment Date payment in shares of Common Stock, the Company is required to deliver a preliminary number of shares of Common Stock 23 days before the applicable Installment Date and, if applicable, an additional number of shares of Common Stock on the Installment Date, in each case, based on formula set forth in the Notes. Generally, the aggregate number of shares of Common Stock delivered in connection with an Installment Date will be valued at the lower of (i) the then applicable fixed conversion price (see below), (ii) a price that is 85% of the arithmetic average of the five lowest volume-weighted average prices of the Common Stock during the 20 trading day period ending the trading day immediately before the date of determination, and (iii) a price that is 85% of the volume-weighted average price of the Common Stock on the trading day immediately before the date of determination. Any payments due to a Note holder may be off-set against any amount in such Note holder’s collateral account described above.

A Note holder may deliver a notice to the Company no later than the business day immediately before an Installment Date electing to have all or a portion of the payment otherwise due on such Installment Date deferred until a subsequent Installment Date elected by the Holder. Any deferred amount will continue to accrue interest. Further, a Note holder may deliver a notice to the Company no later than the third business day immediately before an Installment Date electing to accelerate all or a portion of any amounts scheduled to be paid on future Installment Dates after the applicable Installment Date and request that such accelerated amount be paid in shares of Common Stock on the applicable Installment Date.

The Notes are convertible at any time, at the option of the holders, into shares of Common Stock at the lower of a fixed and floating conversion price. The initial fixed conversion price is $0.8033 per share, subject to adjustment for stock splits and similar events. The floating conversion price is equal to the lowest of (i) 85% of the arithmetic average of the five lowest volume-weighted average prices of the Common Stock during the 20 consecutive trading day period ending on the trading day immediately preceding the delivery of the applicable conversion notice by such holder of Notes, (ii) 85% of the volume-weighted average price of the Common Stock on the trading day immediately preceding the delivery of the applicable conversion notice by such holder of Notes, and (iii) 85% of the volume-weighted average price of the Common Stock on the trading day of the delivery of the applicable conversion notice by such holder of Notes.

Once every six months and subject to certain conditions, the Company has the right to require all holders of the Notes, but not less than all, to convert all or any portion of a Note equal to at least $1,000,000 (or such lesser amount outstanding under a Note) into shares of Common Stock at the conversion price described in the preceding paragraph.

The conversion price used to calculate the number of shares issuable upon conversion of the Notes by the Company or the Note holders may not be less than $0.25 per share. If the conversion price to be used for calculating the shares of Common Stock issuable would have been less than $0.25 per share but for such limitation, the Company is obligated to issue shares of Common Stock at a conversion price of $0.25 and pay cash to the Note holders in an amount calculated pursuant to formulas set forth in the Notes.

A holder may not convert a Note and the Company may not issue shares of Common Stock upon conversion of a Note, including as repayment of principal and interest on an Installment Date, if, after giving effect to the conversion, a holder together with is “attribution parties,” would beneficially own in excess of 9.99% of the outstanding shares of Common Stock. At each holder’s option, the cap may be increased or decrease to any other percentage not in excess of 9.99%, except that any increase will not be effective until the 61st day after notice to the Company.

The Company may not issue any shares of Common Stock under the Notes if the issuance would exceed the aggregate number of shares of Common Stock the Company may issue in the private placement under applicable Nasdaq Rules unless the Company first obtains shareholder approval of such issuance.

The Notes contain customary events of default, the occurrence of which trigger certain acceleration and redemption rights. These events of default include, among other things, failure to make payments or deliver shares of Common Stock under the Notes, breaches of representations, warranties or covenants under the transaction documents, certain indebtedness defaults, and material adverse events. Upon the occurrence of an event of default under the Notes, a holder of a Note may require the Company to redeem all or a portion of its Note. Each portion of the Note subject to such redemption must be redeemed by the Company, in cash, at a price equal to the greater of (i) 125% of the amount being redeemed (including principal, accrued and unpaid interest, and accrued and unpaid late charges) and (ii) the product resulting from multiplying (A) the amount being redeemed (including principal, accrued and unpaid interest, and accrued and unpaid late charges) by (B) the quotient determined by dividing (I) the greatest closing sale price of the Common Stock during the period beginning on the date immediately preceding the event of default and ending on the date the Company pays the entire redemption price to the holder, by (II) the lowest conversion price (see above) in effect during such period. The Note holders may also elect to convert the Notes after the occurrence of an event of default until the 20th trading day immediately following the date such event of default is cured or waived by the Note holders at an event of default conversion price equal to the lowest of (i) the conversion price then in effect, (ii) 70% of the lowest volume-weighted average price of the Common Stock during the 20 consecutive trading day period ending on the trading day immediately preceding the delivery of the applicable event of default conversion notice, and (iii) 70% of the volume-weighted average price of the Common Stock on the date of the applicable event of default conversion.

The terms of the Notes prohibits the Company from entering into a “fundamental transaction” (as defined in the Notes) unless the successor resulting from the fundamental transaction assumes all of the obligations of the Company under the Notes and the transaction documents, and, if a successor is publicly-traded, at a holder’s request, such successor issues substantially similar substitute securities. The definition of “fundamental transactions” includes, but is not limited to, mergers, a sale of all or substantially all of the Company’s assets, certain tender offers and other transactions that result in a change of control.

A Note holder may also require the Company to redeem all or a portion of its Note in connection with a transaction that results in a “change of control” (as defined in the Notes). Each portion of a Note subject to such redemption must be redeemed by the Company, in cash, at a price equal to the greater of (i) 125% of the amount being redeemed (including principal, accrued and unpaid interest, and accrued and unpaid late charges) and (ii) the product resulting from multiplying (A) the amount being redeemed (including principal, accrued and unpaid interest, and accrued and unpaid late charges) by (B) the quotient determined by dividing (I) the greatest closing sale price of the Common Stock during the period beginning on the date immediately preceding the earlier to occur of (x) the consummation of the change of control transaction and (y) the public announcement of the change of control transaction and ending on the date the holder delivers a redemption notice to the Company, by (II) the lowest conversion price in effect during such period. The definition of “change of control” means any “fundamental transactions” other than certain transactions that do not result in a change of control.

At any time, so long as certain equity conditions are satisfied, the Company has the right to redeem all or any portion of the amounts outstanding under the Notes, pro rata among Note holders, in cash at a price equal to the greater of (i) 118% of the amount being redeemed (including principal, accrued and unpaid interest, and accrued and unpaid late charges) and (ii) 115% of the product resulting from multiplying (A) the amount being redeemed (including principal, accrued and unpaid interest, and accrued and unpaid late charges) by (B) the quotient determined by dividing (I) the greatest closing sale price of the Common Stock during the period beginning on the date immediately preceding the date on which the Company delivers a notice of redemption to the Note holders and ending on the redemption date, by (II) the lowest conversion price in effect during such period. The Company may not affect more than one such redemption during any six month period.

The Note holders are entitled to receive any dividend or other distribution of the Company’s assets (or rights to acquire its assets) on an “as if converted into Common Stock” basis. The Note holders are also entitled to acquire options, convertible securities or rights to purchase the Company’s securities or property granted, issued or sold pro rata to the holders of its Common Stock on an “as if converted into Common Stock” basis.

The Notes include certain covenants, including, among others, restrictions on (i) incurrence of indebtedness, (ii) repayment or redemption of indebtedness, (iii) redemption or repurchase of outstanding securities, (iv) making material changes to the Company’s business, and (v) affiliate transaction; and requirement to maintain subsidiaries, assets and insurance.

The Company granted a security interest in the collateral accounts described above to the Investors to secure the Company’s obligations under the Notes. Upon the occurrence of an “equity condition failure” or on any date after September 30, 2016 on which a “public information failure” (as defined in the Notes) exists or is reasonably expected to occur, a Note holder is entitled to cause any amount remaining in such Note holder’s collateral account to be released to such Note holder.

Warrants

The Warrants will be exercisable beginning on the six month anniversary after the date of issuance and will expire five years following the initial exercisability date. The initial exercise price of the Warrants will be equal to $0.8280, subject to adjustments for stock splits and similar events. Further, if the exercise price of the Warrants on March 31, 2017 the “closing bid price” (as defined in the Warrants) of the Common Stock on such date (the “Adjusted Exercise Price”), the exercise price will be reset to the Adjusted Exercise Price. Until the Company obtains shareholder approval of the issuance of shares of Common Stock upon exercise of the Warrants pursuant to Nasdaq Rule 5635, the exercise price may not be adjusted below $0.71. Under certain circumstances, the holders of the Warrants may elect to exercise them through a cashless exercise, in which case the holders will receive upon such exercise the “net number” of shares of Common Stock determined according to the formula set forth in the Warrant and the Company will not receive the exercise price.

A holder may not exercise any of the Warrants, and the Company may not issue shares of Common Stock upon exercise of any of the Warrants if, after giving effect to the exercise or issuance, the holder together with is “attribution parties,” would beneficially own in excess of 9.99% of the outstanding shares of Common Stock. At each holder’s option, the cap may be increased or decrease to any other percentage not in excess of 9.99%, except that any increase will not be effective until the 61st day after notice to the Company.

The holders of the Warrants are entitled to receive any dividend or other distribution of the Company’s assets (or rights to acquire its assets), at any time after the issuance of the Warrants, on an “as if exercised for Common Stock” basis. The holders of the Warrants are entitled to acquire options, convertible securities or rights to purchase the Company’s securities or property granted, issued or sold pro rata to the holders of its Common Stock on an “as if exercised for Common Stock” basis. The Warrants prohibit the Company from entering into transactions constituting a “fundamental transaction” (as defined in the Warrants) unless the successor entity assumes all of the Company’s obligations under the Warrants and the other transaction documents in a written agreement approved by the “required holders” (as defined in the Warrants) of the Warrants. The definition of “fundamental transactions” includes, but is not limited to, mergers, a sale of all or substantially all our assets, certain tender offers and other transactions that result in a change of control.

Purchase Agreement

The Company is obligated to reimburse the lead Investor for costs and expenses incurred in connection with the Purchase Agreement, which amount, at the option of the lead Investor, may be withheld from its purchase price at closing.

The Company has agreed to not issue any additional Notes offered in the private placement in the future so long as an Investor owns any of the securities purchased as part of the Units or any of the shares of Common Stock underlying the Notes or the Warrants. Further, until the earlier to occur of (i) the second anniversary of the closing of the private placement, and (ii) the date on which the aggregate principal amount outstanding under the Notes is less than $4,000,000, the Company may not issue or sell any rights, warrants or options to subscribe for or purchase Common Stock or directly or indirectly convertible into or exchangeable or exercisable for Common Stock at a price which varies or may vary with the market price of the Common Stock, unless the conversion, exchange or exercise price of any such security cannot be less than the then applicable conversion price of the Notes or the then applicable exercise price of the Warrants.
