11.	Long-term Obligations

On June 28, 2013 we entered into a Loan and Security Agreement (the “2013 Loan Agreement”) with Oxford Finance LLC and Silicon Valley Bank (together, the Lenders), pursuant to which the Lenders funded an aggregate principal amount of $27.0 million (Term Loan), subject to the terms and conditions set forth in the 2013 Loan Agreement. The Term Loan accrues interest at a fixed rate of 9.75% per annum. Pursuant to the 2013 Loan Agreement, we are required to make interest only payments through July 1, 2014 and thereafter we are required to make payments of principal and accrued interest in equal monthly installments sufficient to amortize the Term Loan through July 1, 2017, the maturity date. At maturity of the Term Loan, or the earlier repayment in full following a voluntary prepayment or upon acceleration, the Company is required to make a final payment fee in an aggregate amount equal to $1,795,000. In connection with the Term Loan, on June 28, 2013, we issued to the Lenders warrants to purchase up to an aggregate of 596,553 shares of our common stock at an exercise price of $2.26 per share. These warrants are immediately exercisable and will expire on June 28, 2020.

In connection with the funding of the 2013 Loan Agreement, we prepaid all outstanding amounts under the prior loan agreement, at which time the Company’s obligations under the prior loan agreement immediately terminated. The Company paid to the prior agent and the prior lenders approximately $18,866,000, consisting of the then outstanding principal balance due of approximately $17,325,000, accrued but unpaid interest of approximately $119,000, a final payment fee (net of fees waived or refunded by the Lenders under the new loan agreement) of approximately $1,078,000, a prepayment fee (net of fees waived or refunded by the Lenders under the new loan agreement) of approximately $312,000 and other customary lender fees and expenses.

The net proceeds of the Term Loan, after payment of lender fees and expenses and prepaying all the outstanding amounts relating to the prior loan agreement, were approximately $7.8 million.

For the continuing Lenders, we accounted for this amendment as a debt modification. Accordingly, related fees of $1,942,000 were recorded as debt discount from the prior loan, and along with the unamortized debt discount will be amortized as an adjustment of interest expense using the effective interest method. For one existing lender that did not participate in the Term Loan, the payoff of their loan was accounted for as debt extinguishment. Accordingly, a loss on debt extinguishment of $708,000 was recorded, which includes that lender’s portion of unamortized fees and discounts along with prepayment and final payment fees.

On September 19, 2014, we entered into a Letter Agreement with the Lenders pursuant to which the Lenders waived financial covenant compliance pursuant to the 2013 Loan Agreement through October 31, 2014. The 2013 Loan Agreement requires the Company to maintain certain minimum cash balances at all times during the term of the 2013 Loan Agreement. In exchange for the above waiver, the Company agreed to re-price all 596,553 outstanding warrants issued by the Company to Oxford Finance LLC and Silicon Valley Bank pursuant to the 2013 Loan Agreement, with an exercise price per share equal to the lower of (i) the closing price per share of the Company’s common stock on September 30, 2014, or (ii) the average closing price per share of the Company’s common stock for October 1, 2 and 3, 2014.

On September 29, 2014 we entered into a 2^nd Amendment to the 2013 Loan Agreement with the Lenders Pursuant to the amended 2013 Loan Agreement, and we were provided a conditional waiver of principal payments subject to meeting certain capital raise requirements, which we achieved in October. The waiver of principal payments continued through April 1, 2015 and we were then required to make payments of principal and accrued interest in equal monthly installments sufficient to amortize the Term Loan through the maturity date.

On May 29, 2015, we entered into the Loan and Security Agreement (“Loan Agreement”) with Oxford Finance LLC (“Oxford” or “Lender”), pursuant to which the Lender funded an aggregate principal amount of $17.7 million (“Term Loan”), subject to the terms and conditions set forth in the loan agreement. The Term Loan accrues interest at a floating rate of 8.95% per annum, comprised of three-month LIBOR rate with a floor of 1.00% plus 7.95%. Pursuant to the Loan Agreement, we are required to make interest only payments through June 1, 2016 and thereafter we are required to make payments of principal and accrued interest in equal monthly installments sufficient to amortize the Term loan through June 1, 2019, the maturity date. On February 23, 2016, Cytori received an acknowledgement and agreement from Oxford related to the positive data on Cytori US ACT-OA clinical trial. As a result, pursuant to the Loan Agreement, the period for which the Company is required to make interest-only payment was extended from July 1, 2016 to January 1, 2017. All unpaid principal and interest with respect to the Term Loan is due and payable in full on June 1, 2019. At maturity of the Term Loan, or earlier repayment in full following voluntary prepayment or upon acceleration, the Company is required to make a final payment fee in an aggregate amount equal to approximately $1.1 million. In connection with the Term Loan, on May 29, 2015, we issued to the Lender warrants to purchase an aggregate of 1,416,618 shares of our common stock at an exercise price of $0.69 per share. These warrants are exercisable on or after November 30, 2015 and will expire on May 29, 2025 and, following the authoritative accounting guidance, are equity classified.

In connection with the Loan Agreement, we prepaid all outstanding amounts under our prior loan agreement with Oxford and Silicon Valley Bank, at which time the Company’s obligations under the prior loan agreement immediately terminated. The Company paid to the prior agent and the prior lenders (Oxford and Silicon Valley Bank) approximately $25.4 million, consisting of the then outstanding principal balance due of approximately $23.4 million, accrued but unpaid interest of approximately $0.2 million, final payment and other agency fees of approximately $1.8 million and other customary lender fees and expenses.

For Oxford, we accounted for this Term Loan as a debt modification. The Company retired $3.1 million of the principal of the previous loan and the corresponding unamortized fees were expensed. The remaining fees of $0.8 million were recorded as debt discount, and along with the new loan fees, will be amortized as an adjustment of interest expense using the effective interest method. For Silicon Valley Bank, which did not participate in the Term Loan, the payoff of the loan was accounted for as debt extinguishment. Accordingly, a total loss on debt extinguishment of $0.3 million was recorded, which includes the unamortized fees and discounts along with final payment fees.

We allocated the aggregate proceeds of the Term Loan between the warrants and the debt obligations based on their relative fair values. The fair value of the warrants issued to the Lender was calculated utilizing the Black-Scholes option pricing model. The Black-Scholes option-pricing model incorporates various and highly sensitive assumptions including expected volatility, expected term and risk-free interest rates. The expected volatility is based on the historical volatility of the Company’s common stock over the most recent period. The risk-free interest rate for period within the contractual life of the warrant is based on the U.S. Treasury yield in effect at the time of grant. We will amortize the relative fair value of the warrants as a discount of $0.8 million over the term of the loan using the effective interest method, with an effective interest rate of 14.95%. The Term Loan is collateralized by a security interest in substantially all of the Company’s existing and after-acquired assets, subject to certain exceptions set forth in the Loan Agreement and excluding its intellectual property assets, which are subject to a negative pledge.
