7. Commitments and Contingencies

Financing Agreements

In December 2009, we entered into a loan and security agreement with Oxford Capital Financing ("Oxford") pursuant to which we received a three-year term loan in the principal amount of $3.0 million that bears interest at the rate of 13% per annum. We paid Oxford an initial facility fee of $60,000 and are obligated to make a final payment fee of $180,000. Commencing in January 2010, the loan is repayable in monthly interest payments of $32,500 through June 2010 followed by monthly interest and principal installments of $117,665 commencing in July 2010 through December 2012. The loan is secured by our assets and has a provision for pre-payment. We also issued to Oxford, in connection with the loan and security agreement, five-year warrants to purchase 42,254 shares of our common stock at an exercise price of $2.13 per share. The relative fair value attributable to the warrants of $88,995 was recorded as a discount to the debt and corresponding credit to additional paid-in capital. The debt discount will be amortized to interest expense over the life of the debt. Interest on the term loan, consisting of the stated interest rate, initial facility fee, final payment fee and amortization of the discount, is being recognized using the interest method. The effective annual interest rate on the loan is approximately 21.1%.

In September 2010, we amended our loan and security agreement with Oxford pursuant to which we received a thirty-nine month term loan in the principal amount of $5.0 million that bears interest at the rate of 13% per annum. We paid Oxford an initial facility fee of $125,000 and are obligated to make a final payment fee of $300,000. Commencing in October 2010, the loan is repayable in monthly interest payments of $54,167 through June 2011 followed by monthly interest and principal installments of $196,108 commencing in July 2011 through December 2013. The loan is secured by our assets and has a provision for pre-payment. We also issued to Oxford, in connection with the loan and security agreement, five-year warrants to purchase 287,356 shares of our common stock at an exercise price of $0.87 per share. The relative fair value attributable to the warrants of $254,580 was recorded as a discount to the debt and corresponding credit to additional paid-in capital. The debt discount is being amortized to interest expense over the life of the debt. Interest on the term loan, consisting of the stated interest rate, initial facility fee, final payment fee and amortization of the discount, is being recognized using the interest method. The effective annual interest rate on the loan is approximately 22.6%.

On March 15, 2011, we entered into several agreements with entities affiliated with Deerfield Management Company, L.P. (collectively, "Deerfield") pursuant to which Deerfield agreed to provide $20.0 million in funding to us. Funding occurred on April 5, 2011 and we used approximately $7.6 million of proceeds from the Deerfield funding to repay Oxford in full, including required final payments aggregating $480,000. Pursuant to the terms of a facility agreement, we issued Deerfield promissory notes in the aggregate principal amount of $20.0 million. The long-term debt bears interest at 8.5% per annum, payable quarterly, and was originally repayable over five years, with 10% of the principal amount due on the first anniversary, 15% due on the second anniversary, and 25% due on each of the next three anniversaries. We paid Deerfield a facility fee of $0.5 million. The long-term debt is secured by our assets and has a provision for pre-payment. Deerfield has the right to have the long-term debt repaid at 110% of the principal amount in the event we complete a major transaction, which includes, but is not limited to, a merger or sale of our company or the sale of Probuphine. In connection with the facility agreement, we issued Deerfield six-year warrants to purchase 6,000,000 shares of our common stock at an exercise price of $1.57 per share (see Note 9. "Warrant Liability" for further discussion). We also entered into a royalty agreement with Deerfield, in exchange for $3.0 million (see Note 8. "Royalty Liability" for further discussion).

We recorded the promissory notes with an aggregate principal amount of $20.0 million at its face value less a note discount consisting of (i) $3.0 million cash discount, (ii) a $500,000 loan fee, and (iii) the $5.5 million fair value of the associated warrants. The note discount totaling $9.0 million is being amortized using the interest method. The effective annual interest rate on the note was 33% based on the note discount amortization, stated interest rate and note term.

On November 14, 2011, we entered into several agreements with Deerfield pursuant to which we agreed to provide a substantial portion of the remaining future royalties on the sales of Fanapt to Deerfield in exchange for $5.0 million in cash that was recorded as royalty liability (see Note 8 "Royalty Liability" for further discussion), a $10.0 million reduction in the principal amount owed to Deerfield under the existing facility agreement and a revised principal repayment schedule of $2.5 million per year for four years commencing in April 2013 to retire the remaining long-term debt of $10.0 million. We evaluated the November 2011 principal reduction and other amendments to the $20.0 million facility agreement and determined that the modifications should be accounted for as a troubled debt restructuring on a prospective basis. As a result, we will recognize the difference between the carrying value of the long-term debt and the total required future principal and interest payments as interest expense over the remaining term using the interest method.

The following is a schedule of future minimum long-term debt payments at December 31, 2011 (in thousands):

Legal Proceedings

There are no ongoing legal proceedings against the Company.

In March 2005, Dr. Bernard Sabel initiated an appraisal proceeding in the Court of Chancery of the State of Delaware relating to the merger of our subsidiary ProNeura, Inc. into Titan. The complaint indicated that Mr. Sabel wanted the court to appraise the value of the 108,800 shares of the common stock of ProNeura owned by him. The complaint did not specify an amount that Mr. Sabel considered the fair value of the shares. In March 2009, we settled our dispute with Dr. Sabel related to the merger of our subsidiary ProNeura, Inc. into Titan. In April 2009, under the terms of the settlement, we paid $600,000 to Dr. Sabel.
