The Convertible Notes accrue interest at a rate of 5% per annum, compounded quarterly, to be paid on each December 31, March 31, June 30 and September 30, and on the date of any redemption, conversion or exchange of the Convertible Notes. ( 2 )(Continued from Footnote 1) Such interest payments are to be paid in kind by adding the accrued interest to the principal balance of the Convertible Notes; provided, that, following July 31, 2017, Triangle has the option to make such interest payments in cash. Accordingly, on September 30, 2012, accrued interest in the amount of $1,000,000 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $121,000,000. On December 31, 2012, accrued interest in the amount of $1,512,500 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $122,512,500.

On September 30, 2013, accrued interest in the amount of $1,569,930.69 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $127,164,385.77. On December 31, 2013, accrued interest in the amount of $1,589,554.82 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $128,753,940.59. On March 31, 2014, accrued interest in the amount of $1,609,424.26 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $130,363,364.85. On June 30, 2014, accrued interest in the amount of $1,629,542.06 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $131,992,906.91. ( 4 )(Continued from Footnote 3) On September 30, 2014, accrued interest in the amount of $1,649,911.34 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $133,642,818.25. On December 31, 2014, accrued interest in the amount of $1,670,535.23 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $135,313,353.47. On March 31, 2015, accrued interest in the amount of $1,691,416.92 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $137,004,770.39. On June 30, 2015, accrued interest in the amount of $1,712,559.63 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $138,717,330.02. On September 30, 2015, accrued interest in the amount of $1,733,966.63 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $140,451,296.64. ( 5 )(Continued from Footnote 4) On December 31, 2015, accrued interest in the amount of $1,755,641.21 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $142,206,937.85. On March 31, 2016, accrued interest in the amount of $1,777,586.72 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $143,984,524.58. On June 30, 2016, accrued interest in the amount of $1,799,806.56 was added to the principal amount of the Convertible Notes, resulting in an aggregate principal amount of $145,784,331.13.

( 6 )(Continued from Footnote 5) Based on an initial conversion price of $8.00 per share, $1,822,304.14 in principal amount of Convertible Notes would be convertible into 227,788 shares of Common Stock and $147,606,635.27 in principal amount of Convertible Notes would be convertible into 18,450,829 shares of Common Stock.
