A.       The Company, the Holder and other Buyers executed and delivered a Securities Purchase Agreement (the "Securities Purchase Agreement") dated as of June 29, 2016 in reliance upon the exemption from securities registration afforded by Section 4(a)(2) of the 1933 Act, and Rule 506(b) of Regulation D as promulgated by the SEC under the 1933 Act.

C.       In compliance with Section 19 of the Notes, the Company and the Holder, which alone represents the Required Holders (as defined in each of the Notes), desire to further amend each of the Notes as set forth herein, which amendments shall be binding on the holders of all Notes outstanding as of the execution and delivery of this Agreement by the Company and the Holder (such time, the "Effective Time").

NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, hereby agree as follows:

1. NO CHANGE TO TERMS EXCEPT AS SET FORTH. Except as explicitly set forth in this Agreement, all terms of the Securities Purchase Agreement, the Notes, the Warrants, the Security Documents and other Transaction Documents, as amended prior to the date hereof, are, and shall continue to be, in full force and effect and are hereby ratified and confirmed in all respects. Except as explicitly set forth herein, the Holder reserves all of its rights, remedies, powers, and privileges. All references herein and in the Securities Purchase Agreement, the Notes, the Warrants, the Security Documents and other Transaction Documents to the Notes shall mean on and after the Effective Time, respectively, the Securities Purchase Agreement, Notes, Warrants, the Security Documents and such other Transaction Documents, each as amended by this Agreement.

2. CHANGES TO THE NOTES.

a.       Section 3(b)(ii) of the Notes is hereby amended and restated in its entirety, as follows:

"(ii) "Conversion Price" means, as of any Conversion Date or other date of determination, the lowest of (x) $0.50 per share, subject to adjustment as provided herein, (y) 85% of the lower of (I) the lowest Weighted Average Price of the Common Stock and (II) the lowest Closing Bid Price of the Common Stock, in each case, during the five (5) consecutive Trading Day period ending on, and including, the Trading Day on which the Holder delivers a Conversion Notice to the Company (such trading prices to be appropriately adjusted for any share dividend, share split, share combination, reclassification or similar transaction during such five (5) consecutive Trading Day period), and (z) 85% of the Weighted Average Price of the Common Stock during the period beginning at 9:30:01 a.m., New York time (or such other time as the Principal Market publicly announces the official opening of trading), and ending at 1:00:00 p.m., New York time, on the delivery date of the applicable Conversion Notice; provided, however, that during the Restricted Period (as defined in Section 18(c)(i)), the Conversion Price shall not be lowered to an amount lower than 85% of the Weighted Average Price of the Common Stock on the delivery date of the applicable Conversion Notice."

b.       Section 18(c) of the Notes is hereby amended and restated in its entirety, as follows:

"(c) Leak-Out.

(i)       During the period commencing on February 17, 2017 and ending with close of trading on May 1, 2017, inclusive (such period, the "Restricted Period"), neither the Holder, nor any of its Buyer Trading Affiliates (as defined in the Securities Purchase Agreement), collectively, shall sell, directly or indirectly, (including, without limitation, any sales, short sales, swaps or any derivative transactions that would be equivalent to any sales or short positions) shares of Common Stock on any Trading Day during the Restricted Period (any such date, a “Date of Determination”), in an amount that exceeds the greater of (x) 40% of the Holder's Pro Rata Share (as defined below) of the trading volume of Common Stock on the Principal Market (or such other primary market in which the Common Stock is then trading) as reported by Bloomberg for the applicable Date of Determination and (y) the Holder's Pro Rata Share of $150,000 of gross sale proceeds received by the Holder, calculated by multiplying the number of shares of Common Stock sold and the applicable sale price (the greater of (x) and (y), the "Leak Out Limitation"); provided, that to the extent the Required Holders elect to release cash to the Company from its Holder Master Restricted Account pursuant to clause (ii) of the definition of Control Account Company Release Event set forth in Section 33(s) of the Note (a "Voluntary Release") and the Holder does not either (x) elect to effect a Voluntarily Release of cash to the Company from its Holder Master Restricted Account or (y) otherwise fund an amount of cash to the Company, in each case, in an amount corresponding to its Holder's Pro Rata Share of the amount of cash released to the Company by the Required Holders, then, the Holder together with its Buyer Trading Affiliates shall only be entitled to sell, directly or indirectly, (including, without limitation, any sales, short sales, swaps or any derivative transactions that would be equivalent to any sales or short positions) shares of Common Stock on any Date of Determination in an amount up to fifty percent (50%) of its Leak Out Limitation as determined pursuant to this Section 18(c)(i) until, the next time, if any, that the Required Holders elect to effect a Voluntary Release, in which case the Holder's ability to sell shares of Common Stock during the Restricted Period shall again be determined pursuant to this Section 18(i), including, without limitation pursuant to this proviso; provided, further, that, notwithstanding anything herein to the contrary, neither the Holder, nor any of its Buyer Trading Affiliates shall sell, directly or indirectly, (including, without limitation, any sales, short sales, swaps or any derivative transactions that would be equivalent to any sales or short positions) any Common Stock on the date the Company effects a reverse stock split and on the two (2) Trading Days immediately following such date. As used herein, "Holder's Pro Rata Share" means a fraction (i) the numerator of which is the outstanding Principal amount of this Note on February 17, 2017 and (ii) the denominator of which is the sum of (x) the outstanding Principal amount of this Note on February 17, 2017 and (y) the outstanding principal amounts of all Other Notes on February 17, 2017.

(ii)       Notwithstanding anything herein to the contrary, during the Restricted Period, the Holder may, directly or indirectly, sell or transfer all, or any part, of this Note or the Holder's Warrants (or any securities issuable upon conversion or exercise of this Notes or the Holder's Warrants, as applicable) (the “Restricted Securities”) to any Person (an “Assignee”) without complying with (or otherwise limited by) the restrictions set forth in this Section 18(c); provided, that as a condition to any such sale or transfer an authorized signatory of the Company and such Assignee duly execute and deliver an agreement containing the same provisions as contained in this Section 18(c) (an “Assignee Agreement”) and sales of the Holder and its Buyer Trading Affiliates and all Assignees shall be aggregated for all purposes of this Section 18(c) and all Assignee Agreements."

For the avoidance of doubt, after giving effect to the foregoing amendment, the Holder's Pro Rata Share for the Holder as of the date hereof shall be %.
