Warrants

In connection with the execution of the Facility Agreement, on March 17, 2014, the Company issued to Deerfield warrants to purchase an aggregate of 6,250,000 shares of the Company’s common stock immediately exercisable at an exercise price equal to $1.39 (the “Initial Warrants”) expiring on March 17, 2020. The number of shares of common stock into which the Initial Warrants are exercisable and the exercise price will be adjusted to reflect any stock splits, payment of stock dividends, recapitalizations, reclassifications or other similar adjustments in the number of outstanding shares of the Company’s common stock. The warrants have the same dividend rights to the same extent as if the warrants had been exercised for shares of common stock.

Each disbursement borrowing under the Facility Agreement shall be accompanied by the issuance to Deerfield of additional warrants to purchase up to an aggregate of 10,000,000 shares of the Company’s common stock, at an exercise price equal to the lesser of the Initial Warrant exercise price or the average daily volume weighted average price per share of the Company’s common stock for the 15 days following the request for borrowing (the “Draw Warrants”). The number of Draw Warrants issued for each draw will be in proportion to the amount of draw compared to the total $50 million facility.

The Initial Warrants were valued on March 17, 2014 using a Black-Scholes option pricing model that resulted in a value of $5.7 million, which was recorded as a current liability with an offset to a deferred charge asset and will be amortized on a straight line basis through interest expense over the term of the Facility Agreement commitment period ending January 30, 2015. To the extent the Company draws on the $50 million Facility Agreement, a proportionate amount of the unamortized current deferred charge will be reclassified as debt discount and amortized through interest expense over the term of the debt using the effective interest method.

On March 20, 2014, the Company made an initial draw of $20 million under the Facility Agreement and received net proceeds of $19.5 million to fund the portion of the Orthotec settlement payment obligations that are due in 2014. In connection with this borrowing, the Company issued Draw Warrants to purchase 4,000,000 shares of common stock at an exercise price of $1.39. The Draw Warrants were valued at $4.7 million using the Black-Scholes option pricing model, which was recorded as a current liability with an offset to debt discount. In connection with the $20 million draw, $2.3 million of the deferred charge recorded upon the issuance of the Initial Warrants was reclassified as a debt discount.

As of June 30, 2014, the 10,250,000 outstanding Initial Warrants and Draw Warrants were revalued to their fair value with a charge to other income (expense) of $0.9 million and $0.8 million for the three and six months ended June 30, 2014. The warrant liability of $11.2 million is recorded as common stock warrant liabilities within current liabilities on the condensed consolidated balance sheet as of June 30, 2014.

At June 30, 2014, our outstanding warrants were valued using the Black-Scholes option pricing model. This is a Level 3 measurement using the following assumptions:
