Note Payable


The Company had a $2,000,000 subordinated secured convertible note (“April 2011 Note”) payable to a medical device co-development partner (“Strategic Partner”). Upon issuance, the April 2011 Note was scheduled to mature in April 2016, unless earlier converted, and it accrued interest at the rate of 10% per year. The April 2011 Note was amended in February 2012, to, among other things, provide the Strategic Partner the option to convert the April 2011 Note into shares of the Company’s common stock at a conversion price of $0.60 per share at any time on or before February 23, 2013.


On February 21, 2013, the Strategic Partner delivered notice to the Company of its election to convert the April 2011 Note into shares of the Company’s common stock at the conversion price of $0.60 per share. However, prior to the issuance of those conversion shares, on March 6, 2013, the Company and the Strategic Partner entered into a loan modification. As a result of that loan modification, the Strategic Partner revoked its election to convert the April 2011 Note into shares of common stock. Under the loan modification, the Company issued an amended and restated subordinated secured note to the Strategic Partner (the “Amended and Restated Note”) which amended the April 2011 Note (i) to remove the equity conversion feature, such that the Amended and Restated Note is not convertible into any shares of the Company’s capital stock, (ii) to reduce the interest rate, beginning March 6, 2013, from 10% per year to 5.5% per year, (iii) to ease certain restrictive loan covenants, and (iv) to reflect a new note principal balance of $4,289,444, which represents the sum of (A) the original principal balance of the April 2011 Note in the amount of $2,000,000, plus (B) interest accrued under the April 2011 Note through March 6, 2013 in the amount of $389,444, plus (C) $1,900,000. The Amended and Restated Note completely replaced and superseded the April 2011 Note. The Amended and Restated Note matures in April 2016, and principal and accrued interest under the Amended and Restated Note is payable in a single installment upon maturity. Like the April 2011 Note, the Amended and Restated Note is secured by a security interest in the assets of the Company, which security interest is junior and subordinate to the security interest that secures the Boston Scientific Notes.


The Company calculated the fair value of the Amended and Restated Note, as of the loan modification date, based on the amended terms. On the date of the loan modification, the fair value of the Amended and Restated Note, with its principal balance of $4,289,444, was $3,745,621. The difference between the fair value of the Amended and Restated Note on the date of the loan modification and the carrying value of the April 2011 Note and related accrued interest immediately prior to the loan modification, resulted in a charge to other expense of $1,356,177 in the statement of operations during the year ended December 31, 2013. The $543,823 difference between the principal amount of the Amended and Restated Note and the fair value of the Amended and Restated Note on the date of the loan modification was recorded as a debt discount and is being amortized to interest expense using the effective interest method over the term of the Amended and Restated Note.


Junior Secured Notes Payable


In November 2010, the Company issued an aggregate of 10,714,286 units and received proceeds of $3,000,000. The units were sold to existing stockholders and other existing securityholders of the Company. Each unit consisted of a junior secured note, and one share of the Company’s common stock. The Company issued 10,714,286 shares of common stock and junior secured notes in the aggregate principal amount of $3,000,000. The notes mature in November 2020 and accrue interest at the rate of 3.5% per year. The notes are secured by a security interest in the assets of the Company, which security interest is junior and subordinate to the security interests that secure the Boston Scientific Notes and the Amended and Restated Note. All outstanding principal and interest on the junior secured notes will be due and payable in a single payment upon maturity.


Under GAAP, the Company allocated the $3,000,000 in proceeds from the sale of the units between the junior secured notes and the shares of common stock based on their relative fair values, with $2,775,300 being recorded as equity. The junior secured notes were recorded at the principal amount of $3,000,000 less a discount of $2,775,300. This discount is being amortized to interest expense over the 10-year term of the notes using the effective interest method. The fair value of the notes was estimated based on an assumed market interest rate for notes of similar terms and risk. The fair value of the Company’s common stock was estimated by management using a market approach, with input from a third-party valuation specialist.


Four officers of the Company purchased an aggregate of 882,726 units in the offering for $247,164. In addition, three non-employee directors of the Company also purchased an aggregate of 567,203 units for $158,816 in the offering.
