Secured Loan Agreement with Elkhorn Partners.

On February 11, 2013, the Company and Elkhorn Partners Limited Partnership (“Elkhorn”), entered into a Secured Loan Agreement (the “Elkhorn Loan Agreement”) and a Stock Purchase Agreement (the “Elkhorn SPA”), and certain related agreements, which are described below (collectively, the “Elkhorn Agreements”). Pursuant to those Elkhorn Agreements, Elkhorn made a $1.5 million senior secured loan to the Company with a maturity date of November 30, 2014 and purchased a total of 6,250,000 shares of the Company’s common stock at a cash purchase price of $0.16 per share, generating an additional $1.0 million of cash for the Company. The average of the closing prices of the Company’s common stock in the over-the-counter market for the five trading days immediately preceding February 11, 2013 was $0.14 per share and, for the 29 trading days that began on January 2, 2013 and ended on February 8, 2013, was $0.158 per share. On February 11, 2013, the Company used approximately $2.1 million of the proceeds of $2.5 million from the Elkhorn Loan and the sale of the shares to Elkhorn to pay the entire principal amount of and all accrued interest on the Broadwood Loan. On June 3, 2014, the Company repaid the Elkhorn Loan Agreement in full.

The Elkhorn Loan, which was evidenced by a promissory note (the “Elkhorn Loan”), issued by the Company to Elkhorn, bore interest at 7% for the first 12 months of the Elkhorn Loan, increasing to 8.5% thereafter and continuing until the Elkhorn Loan was paid in full.

The Elkhorn Loan Agreement provided that if and to the extent the Company did not pay the Elkhorn Loan in full by its Maturity Date, then, Elkhorn would have had the right, at its option (but not the obligation), to convert the then unpaid balance of the Elkhorn Loan, in whole or in part, into shares of Company common stock at a conversion price of $0.25 per share. That conversion price was subject to possible adjustment on (i) certain sales of Company common stock at a price lower than $0.25 per share, (ii) stock splits of, stock dividends on and any reclassification of the Company’s outstanding shares, and (iii) certain mergers or reorganizations of the Company, as provided in Article III of the Elkhorn Loan Agreement. This conversion feature created a derivative liability that is described in Note 9.

Elkhorn Stock Purchase Agreement

Concurrently with the Company’s entry into the Elkhorn Loan Agreement, the Company and Elkhorn entered into the Elkhorn SPA Agreement. Pursuant to that Elkhorn SPA Agreement, the Company sold 6,250,000 shares of its common stock to Elkhorn at a price of $0.16 per share, resulting in an aggregate purchase price of $1.0 million.

Senior Secured Six Month Term Loan Agreement and Stock Purchase Agreement

The Company entered into a Senior Secured Six Month Term Loan Agreement dated July 27, 2012 (the “Broadwood Loan Agreement”) with Broadwood, a partnership managed by Broadwood Capital, Inc., the general partner of Broadwood. Broadwood is a significant shareholder of the Company.

Pursuant to that Broadwood Loan Agreement, Broadwood made a $2,000,000 senior secured six month loan (the “Broadwood Loan”) to the Company and to CWT, as co-borrower. The Broadwood Loan bore interest at 5% per annum, ranked senior in right of payment to all other indebtedness of the Company and was due and payable in full on January 28, 2013.

Stock Purchase Agreement and Stock Purchase Warrants

Concurrently with the execution of the Broadwood Loan Agreement, the Company and Broadwood entered into the Broadwood SPA. That agreement provided for the purchase by Broadwood of up to 3,000,000 shares of the Company’s common stock (the “Shares”), at a price of $1.00 per Share, subject to the following conditions: (i) during the six month term of the Broadwood Loan, the Company would use its best commercial efforts to raise at least $3.0 million from the sale of additional equity securities to other investors, which could include other shareholders of the Company, and (ii) the Company remained in compliance with its covenants under the Broadwood Loan Agreement. The Broadwood SPA provided that if, at any time between July 27, 2012 and July 27, 2013, the Company sold any shares of its common stock (or sells or issues securities that are convertible or exercisable into shares of common stock) at a price less than $1.00 per share, the Company would be required to issue outright to Broadwood, without additional consideration from it, a number of additional Shares (the “Make-Whole Shares”) sufficient to reduce the per share price paid by Broadwood for the total number of the Shares and Make-Whole Shares issued under the Broadwood SPA to that lower price.

As consideration for the Broadwood Loan and Broadwood’s entry into the Broadwood SPA, on July 27, 2012 the Company issued stock purchase warrants (the “Warrants”) to Broadwood entitling it to purchase up to a total of 1,704,546 shares of the Company’s common stock (the “Warrant Shares”), at a price of $1.00 per Warrant Share, at any time through July 2020.

On July 27, 2012, the Company also entered into a Warrant Commitment Letter, which provided that if the Company raised less than $3.0 million from sales of equity securities to other investors during the six month term of the Broadwood Loan, then Broadwood will receive an additional Warrant (the “Additional Warrant”) entitling it to purchase, also at a price of $1.00 per share, an amount of shares of the Company’s common stock to be determined based on a formula in the Warrant Commitment Letter, with such amount not to exceed 1,000,000 additional shares (the amount of such additional shares, “Additional Warrant Shares”). The exercise price is to be adjusted if the Company completed subsequent financings at less than the current exercise price as described below.

The Warrants, including the Additional Warrant, provide that if the Company sold shares of its common stock (or any securities that were convertible or exercisable into shares of Company common stock) at a price less than $1.00 per share, then, subject to certain exceptions (including grants of stock incentives and sales of shares to officers, employees or directors under the Company’s equity incentive plans and issuances of shares in business acquisitions), the exercise price of the Warrants, including the Additional Warrant, then outstanding would be reduced to that lower price and the number of Warrant Shares purchasable by Broadwood on exercise of the Warrants and the Additional Warrant will be proportionately increased. The Warrants and the Additional Warrant were accounted for as derivative liabilities resulting from the instruments’ price protection features.

The Warrants and the Additional Warrant (collectively, the “Broadwood Warrants”) also grant to Broadwood the right to require the Company (i) to register the Warrant Shares under the Securities Act of 1933, as amended (the “Securities Act”) for possible resale and (ii) to include the Warrant Shares in any registration statement that the Company may file to register, under the Securities Act, the sale of Company shares for cash.

The Company was informed by Broadwood on January 28, 2013, that it was Broadwood’s position that one or more of the conditions precedent to its obligation to purchase the Company’s shares pursuant to the Broadwood SPA had not been satisfied and, as a result, Broadwood would not consummate that purchase.

The Company’s position was that, contrary to Broadwood’s assertions, all of the conditions under the Broadwood SPA had been satisfied, and Broadwood’s refusal to purchase 3,000,000 shares of Company common stock, at the price of $1.00 per share, constituted a material breach by Broadwood of its obligations under the Broadwood SPA. As a result, as of the date of filing this report, the Company had not issued any Additional Warrant Shares to Broadwood and each party had reserved its rights under and with respect to the Broadwood SPA and the Broadwood Warrants.

On August 13, 2014, the Company and Broadwood entered into an Amendment and Release Agreement that resolves the disputes between the Company and Broadwood concerning the Stock and Warrant Documents and related matters. Pursuant to the Amendment and Release Agreement, the Company issued Broadwood a new stock purchase warrant (“New Warrant”) entitling it to purchase up to a total of 2,350,000 shares of the Company’s common stock, at a price of $0.16 per share, in exchange for cancellation of the Original Warrants and any obligation of the Company to issue the Additional Warrant. The New Warrant expires on July 27, 2020. In addition, the Company and Broadwood released each other from any and all claims concerning the Stock and Warrant Documents and related matters. The derivative liability associated with the Broadwood warrants was reversed on the cancellation date.The replacement warrants qualified for classification as equity and added to additional paid – in capital.
