As previously disclosed on the Current Report on Form 8-K filed with the SEC on June 29, 2016, on June 29, 2016, Great Basin Scientific, Inc. (the “Company”) entered into a Securities Purchase Agreement (the “2016 SPA”) in relation to our issuance and sale to certain buyers as set forth in the Schedule of Buyers attached to the 2016 SPA (the “ 2016 Note Buyers”) of $75 million aggregate principal amount of senior secured convertible notes (the “2016 Notes”) and related Series H common stock purchase warrants (the “Series H Warrants”).

On January 23, 2017, the Company and certain 2016 Note Buyers holding enough of the 2016 Notes to constitute the required holders under Section 19 of the 2016 Notes entered into separate agreements (each, an “Amendment Agreement”). Pursuant to the terms of the Amendment Agreements, our 2016 Notes were amended such that with respect to any conversion notices to convert any 2016 Note delivered to the Company during the period from January 24, 2017 to February 17, 2017, the conversion price of such 2016 Note may not be lower than 90% of the weighted average price of our common stock on the delivery date of the applicable conversion notice.

Also Pursuant to the terms of the Amendment Agreements, all of the 2016 Notes were amended to alter the leak-out provisions previously added to the 2016 Notes pursuant to the amendment agreements entered into between the Company and the 2016 Note Buyers on January 22, 2017, as reported in the Company’s Current Report on Form 8-K filed on January 23, 2017.

The Amendment Agreements amend the terms of the 2016 Notes to change the restriction percentage from 55% to the Holder’s pro rata percentage of 45% of the trading volume of our common stock, unless our common stock is then trading above $0.50 (as adjusted for stock splits, stock dividends, recapitalizations and similar events).

The foregoing is a summary description of the material terms of the Amendment Agreements and is qualified in its entirety by the form of Amendment Agreement, attached as Exhibit 10.1 to this Current Report on Form 8-K and incorporated by reference to this Item 1.01.

The information disclosed in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 3.03.
