(1)	On March 28, 2013, Mr. Essig settled a prepaid variable forward sale contract that was entered into on December 14, 2004, with Credit Suisse First Boston Capital LLC ("CSFB"). The contract obligated Mr. Essig to deliver to CSFB between 264,550 and 500,000 shares of Integra common stock (or at his election, an equivalent amount of cash) on the maturity date of the contract (March 28, 2013). The contract provided that the number of shares of Integra common stock that Mr. Essig would be obligated to deliver to CSFB on the maturity date would depend on the average price of Integra common stock for the 20 trading days prior to and including the settlement date. On March 28, 2013, the settlement price was $40.5266 per share. Accordingly, Mr. Essig transferred to CSFB 417,998 shares of Integra common stock.
