AMENDMENT #6

This Amendment #6 (this “Amendment”) is entered into as of January 20, 2016, by and between Tonaquint, Inc., a Utah corporation (“Lender”), and Guided Therapeutics, Inc., a Delaware corporation (“Debtor”).

A. Debtor previously issued to Lender a Secured Promissory Note dated September 10, 2014 and in the principal amount of $1,275,000.00 (the “Note”).

B. The Note was issued pursuant to a Note Purchase Agreement dated September 10, 2014 between Lender and Debtor (the “Purchase Agreement”) and secured pursuant to a Security Agreement dated September 10, 2014 by Debtor in favor of Lender (the “Security Agreement” and together with the Note, the Purchase Agreement and all other documents entered into in conjunction therewith (including all amendments thereto, the “Loan Documents”).

C. Lender and Debtor previously agreed on March 10, 2015, May 4, 2015, June 1, 2015, June 16, 2015 and June 30, 2015 to amend the Loan Documents to, among other things, extend the Maturity Date (as defined in the Note) of the Note (the June 30, 2015 amendment, “Amendment #5”).

D. Lender and Debtor desire to clarify the operation of certain provisions in the Loan Documents in the event of a stock dividend, stock split, or reclassification of the Company’s common stock.

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

1.                  Recitals. Each of the parties hereto acknowledges and agrees that the recitals set forth above in this Amendment are true and accurate and are hereby incorporated into and made a part of this Amendment.

2.                  Treatment of Stock Dividends, Stock Splits, or Stock Reclassifications. Section 7(c) of Amendment 5 is hereby amended and restated to read as follows:

(c) The conversion price per share (the “Conversion Price”) for each Conversion shall be the lower of (i) $0.25 (such price to be equitably adjusted for any stock dividends, stock splits, or stock reclassifications), and (ii) 75% of the lowest daily volume weighted average price per share of Debtor’s common stock (as reported by Bloomberg, L.P.) during the five (5) business days immediately prior to the date of the applicable Conversion. Notwithstanding the foregoing, the Conversion Price shall be subject to a conversion floor of $0.15 per share (as equitably adjusted for any stock dividends, stock splits, or stock reclassifications, the “Conversion Floor”). If Lender submits a Conversion Notice with a Conversion Price less than the Conversion Floor, then Debtor shall, within two (2) business days of Lender’s delivery of such Conversion Notice, notify Lender in writing of its election to either (i) pay the conversion amount in cash, or (ii) waive the Conversion Floor and deliver the Conversion Shares. On or prior to the Delivery Deadline, Debtor shall pay the aggregate Conversion Price in cash or deliver the applicable Conversion Shares, as the case may be. If Debtor fails to deliver a notice as required pursuant to this Section 5(c), then Debtor shall be deemed to have elected to have waived the Conversion Floor and will be required to deliver the applicable Conversion Shares on or before the Delivery Date.
