6. Convertible Notes

From December 2009 through December 2015, Diffusion LLC issued unsecured convertible promissory notes (the “Convertible Notes”) for gross proceeds of $22,384,320. The Convertible Notes bear interest at either 1% or 1.5% per annum. The Convertible Notes accrue interest beginning on the date of issuance, with the principal and accrued interest due upon the earlier of the maturity date or conversion date. At any time prior to the maturity date, the holders may elect to convert, in whole or in part, the Convertible Notes and any related accrued but unpaid interest into common stock of the Company at a price per share equal to the conversion price. The current and noncurrent portions of accrued interest are included within accrued expenses and other liabilities, respectively, on the accompanying balance sheets.

In the event of a Change of Control or a Qualified Financing (each as defined below), the holders of the Convertible Notes may declare the aggregate outstanding amount of the Convertible Notes to be immediately due and payable or may elect to convert the Convertible Notes and any accrued but unpaid interest as if such conversion took place on the maturity date. A Change of Control is defined as: (i) a merger or consolidation in which the members immediately prior to the transaction do not own, directly or indirectly, more than 50% of the membership interest of the surviving company; (ii) the acquisition of more than 50% of the Company's outstanding membership interest by a single person, entity or group or persons or entities acting in concert or (iii) the sale or transfer of all or substantially all of the assets of the Company. A Qualified Financing is defined as a sale of units or other transaction that results in gross proceeds to the Company of at least $15,000,000, including the conversion of the Convertible Notes. Through the date the financial statements were available to be issued, there have been no Change of Control or Qualified Financing events.

The Company may prepay the Convertible Notes, in full or in part, at any time on a pari passu basis. Upon receipt of notice that the Company intends to prepay the Convertible Notes, holders will have the option to convert their notes in lieu of payment.

At the effective time of the Merger, $1,125,000 in aggregate principal amount of Convertible Notes were outstanding and

the rights of the holders of each such outstanding Convertible Note convertible into Diffusion Units were converted into the right to convert such securities into a number of shares of the Company’s common stock equal to the number of Diffusion Units such Convertible Note would be convertible into pursuant to its terms multiplied by the Exchange Ratio.
