Note 4. CONVERTIBLE NOTES PAYABLE	From October 21, 2011 to April 26, 2012, the Company issued convertible notes for $600,000 (the "Convertible Notes") of which $200,000 was received on October 21, 2011, $100,000 was received on January 31, 2012 and $300,000 was received on April 26, 2012. Additionally, the note holder was issued warrants for 6,000,000 shares of the Company’s common stock with an exercise price of $0.05 that expire on October 15, 2015 ("Warrants"). During September 2015, the Company and the holder mutually agreed to extend the expiration of the 6,000,000 warrants to October 15, 2018, the rest of the terms of the warrants remained the same. The incremental fair value for the modification of the warrants was valued at $190,000 and recorded to additional paid in capital. The conversion feature to the note payable has been accounted for as an original issue discount approximating $296,000 which has been fully accreted as of December 31, 2012. The warrant associated with the note has been accounted for as a debt discount with an approximate value of $296,000 which has been allocated to the note’s fully accreted value of $896,000 (original note amount plus original debt discount) on proportionate basis which amounted to $195,000. The warrant value of $252,000 was determined using the Black-Scholes option pricing model based on the following assumptions: 2 year term; volatility rate of 134% to 135%; and discount rate of 2.5%. For the year ended December 31, 2012, the Company has recorded an expense associated with original debt discount and expense associated with the debt discount (warrants) of $422,000. Accordingly, the carrying net value of this note at December 31, 2016, and 2015 was $0. In October 2015, the Company had issued 15,045,513 shares of common stock related to the conversion and extinguishment of the notes. During 2014 and 2013, the Company issued convertible notes for $2,500,000 through its wholly-owned subsidiary, Senior Scientific, LLC. The convertible notes bear interest at 8%, mature four years from the date of issuance, and are convertible into either: (1) membership interests of Senior Scientific, LLC equal to the quotient of the principal due of the convertible notes divided by $2,500,000 multiplied by 18% of the total equity of Senior Scientific, LLC outstanding as of the date hereof; or (2) the number of shares of common stock of the Company equal to the quotient of the principal and interest payable due of the convertible notes divided by a conversion price of $0.055 per share. The Company may not prepay the convertible notes. In the event of a default and so long as the default exists, interest on the convertible notes will accrue at 10%. The Company must account for all accrued interest on the convertible notes on the first calendar day of each quarter. The conversion feature to the note payable has been accounted for as an original issue discount approximating $1,045,000 which $684,000 has been accreted as of December 31, 2016. The Company has recorded the accreted original issue discount as interest expense totaling $262,000 and $261,000 for the years ended December 31, 2016 and 2015. Accordingly, the carrying net value of these notes at December 31, 2016 and 2015 totals $2,139,000 and $1,877,000, respectively, comprising of $2,500,000 (original face value) plus the unamortized debt discount of $360,000 at December 31, 2016, and unamortized original debt discount of $622,000 at December 31, 2015.
