Note 7 - Financing Transactions

Controlled Equity Offering

On March 25, 2013, we entered into a controlled equity offering arrangement with a sales agent pursuant to which we may offer and sell, from time to time, through the agent shares of our common stock having an aggregate offering price of up to $15.0 million. Under the arrangement, the agent may sell shares by any method permitted by law and deemed to be an "at-the-market" offering as defined in Rule 415 promulgated under the Securities Act of 1933, as amended, including sales made directly on NYSE MKT, or any other existing trading market for our Common Stock or to or through a market maker. Subject to the terms and conditions of that agreement, the agent will use commercially reasonable efforts, consistent with its normal trading and sales practices and applicable state and federal law, rules and regulations and the rules of NYSE MKT, to sell shares from time to time based upon our instructions. We are not obligated to sell any shares under the arrangement. We are obligated to pay the agent a commission of 3.0% of the aggregate gross proceeds from each sale of shares under the arrangement.

Through September 30, 2013, we sold 3,883,173 shares of our common stock under this arrangement resulting in net proceeds (net of commission and offering costs) to the Company of approximately $5.9 million. As of September 30, 2013, aggregate gross sales for additional common stock of approximately $8.6 million remained available under the arrangement. Under the terms of the Merger Agreement with Theraclone Sciences (see Note 3), we are currently prohibited from using the controlled equity offering arrangement.

Loan Agreement with GE Capital

On March 30, 2012, we entered into a Loan Agreement with GE Capital. The Loan Agreement provides for a senior secured debt facility, including a $2.5 million term loan and a revolving line of credit of up to $5 million based on our outstanding qualified accounts receivable. On March 30, 2012, the term loan was funded for the full $2.5 million.

Under the terms of the revolving line of credit, the Company may draw down from the revolving line of credit up to 85% of qualified billed accounts receivable and 80% of qualified unbilled accounts receivable. As of September 30, 2013, the total amount available to draw was approximately $0.7 million, none of which was drawn and outstanding under the line of credit.

The fixed interest rate on the term loan is 10.14% per annum. The revolving line of credit has an adjustable interest rate based upon the 3-month London Interbank Offered Rate (LIBOR), with a floor of 1.5%, plus 5%. As of September 30, 2013, the interest rate was 6.5%. Both the term loan and the revolving line of credit mature in September 2015. Payments on the term loan were originally interest-only for the first 10 months (which has since been extended to 12 months pursuant to terms of the agreement); subsequently, the term loan will fully amortize over its remaining term. Remaining principal payments on the term loan are scheduled as follows:

Year	Principal Payments
2013	$	249,999
2014		999,996
2015		750,007
	$	2,000,002

The term loan, net of a debt discount of $25,593, is recorded on our unaudited condensed consolidated balance sheet as follows:

Current portion of long-term debt		$	999,996
Long-term debt, less current portion		$	974,413

If we prepay the term loan and terminate the revolving line of credit prior to the scheduled maturity date, we are obligated to pay a prepayment premium equal to 3% of the then outstanding principal amount of the term loan if prepaid during the first two years of the loan and 2% if prepaid during the third year or thereafter. In addition, we are obligated to pay a final payment fee of 3% of the term loan balance. The final payment fee is being accrued and expensed over the term of the agreement, using the effective interest method and is included in other long-term liabilities on our unaudited condensed consolidated balance sheet.

Our obligations under the Loan Agreement are collateralized by a security interest in substantially all of our assets. While the security interest does not, except in limited circumstances, cover our intellectual property, it does cover any proceeds received by us from the use or sale of our intellectual property.

In connection with the Loan Agreement, we issued GE Capital warrants to purchase 46,584 shares of our common stock at an exercise price of $1.61 per share. The warrants were exercisable immediately and subject to customary and standard anti-dilution adjustments. The warrants are classified in equity and, as a result, the fair value of the warrants was charged to additional paid-in capital resulting in a debt discount at the date of issuance. The debt discount is being amortized over the term of the loan agreement using the effective interest method. Financing costs incurred in connection with this agreement are also being amortized over the term of the agreement using the effective interest method.

The estimated fair value of the Company's outstanding borrowings under its revolving credit facility at December 31, 2012 was equal to its carrying value as of that date due to the short term nature of the Revolver's repayment terms. The Company determined the estimated fair value of the Term Loan also approximated its carrying value as of September 30, 2013.
