5. Commitments and Contingencies

Financing Agreements

        On March 15, 2011, we entered into several agreements with entities affiliated with Deerfield Management, a healthcare investment fund (collectively, "Deerfield"); pursuant to which Deerfield agreed to provide $20.0 million in funding to us. The agreements were funded on April 5, 2011 and $7.7 million of the proceeds were used to repay our outstanding indebtedness to Oxford Capital Financing ("Oxford"). Pursuant to the terms of a facility agreement, we issued promissory notes to Deerfield in the aggregate principal amount of $20.0 million. The loan bears interest at 8.5% per annum, payable quarterly, and the facility is 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 $500,000. The facility is secured by our assets and has a provision for pre-payment. Deerfield has the option to have the loan 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 Fanapt or Probuphine. Under a royalty agreement, we agreed to pay Deerfield 2.5% of the aggregate royalties on net sales of Fanapt, beginning on the funding date, constituting a portion of the royalty revenue we receive from Novartis. The agreements with Deerfield also provide us with the option to repurchase the royalty rights for $40.0 million. Deerfield received six-year warrants to purchase 6,000,000 shares of common stock at an exercise price of $1.57 per share.

The $20.0 million note was recorded at its face value less a note discount consisting of $3.0 million, a $500,000 loan fee, and the $7.1 million fair value of the associated warrants. The note discount totaling $8.9 million is being amortized using the interest method. The effective annual interest rate on the note is 33% based on the note discount amortization, stated interest rate and note term. The $3.0 million received under the Royalty Sales Agreement (RSA) was recorded as a loan in accordance with appropriate accounting guidance. Interest on the loan will be recorded using the interest method based on the estimated future royalties expected to be paid under the RSA. The current effective annual interest rate on the loan is 58.2%.

In September 2010, we amended our loan and security agreement with Oxford pursuant to which we received a 39 month term loan in the principal amount of $5.0 million bearing interest at the rate of 13% per annum. We paid Oxford an initial facility fee of $125,000 and were obligated to make a final payment fee of $300,000. Commencing in October 2010, the loan was repayable in monthly interest payments of $54,167 through July 2011 followed by monthly interest and principal installments of $196,108 commencing in August 2011 through January 2014. The loan was secured by our assets and had 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 was amortized to interest expense. The Oxford indebtedness was repaid on April 5, 2011 with proceeds from the Deerfield transaction.

In December 2009, we entered into a loan and security agreement with Oxford pursuant to which we received a three-year term loan in the principal amount of $3,000,000 that bears interest at the rate of 13% per annum. We paid Oxford an initial facility fee of $60,000 and were obligated to make a final payment fee of $180,000. Commencing in January 2010, the loan was repayable in monthly interest payments of $32,500 through June 2010 followed by monthly interest and principal installments of $117,625 commencing in July 2010 through December 2012. The loan was secured by our assets and had 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 was amortized to interest expense. The Oxford indebtedness was repaid on April 5, 2011 with proceeds from the Deerfield transaction.

Royalty Payments

In 1997, we entered into an exclusive license agreement with Sanofi-Aventis SA (formerly Hoechst Marion Roussel, Inc.). The agreement gave us a worldwide license to the patent rights and know-how related to the antipsychotic agent Fanapt (iloperidone), including the ability to develop, use, sublicense, manufacture and sell products and processes claimed in the patent rights. Upon commercialization of the product, the license agreement provides that we will pay royalties based on net sales. Net sales of Fanapt by Novartis during the three month period ended June 30, 2011 and 2010 were approximately $7.5 million and $0.7 million, respectively, and we were obligated to pay royalties of approximately $1.1 million and $0.1 million to Sanofi-Aventis on June 30, 2011 and 2010, respectively, which were included in Receivables and Accounts Payable on the Condensed Consolidated Balance Sheets.
