F1: These shares were awarded to the Reporting Person by the Company pursuant to the Company's standard director compensation arrangements for non-employee directors. The award is subject to an agreement providing restrictions and other conditions on the resale of the shares as well as for their possible forfeiture under certain circumstances.

F2: This amendment to the May 8, 2012 Form 4 of the Reporting Person and the amendment preceding it was caused by multiple errors in the reported closing price of the Company's common stock on May 8, 2012, the basis of the calculation of the number of shares issued to the Reporting Person. On May 9, 2012, NASDAQ reported the May 8 closing price as $9.70 per share; on May 10, 2012 NASDAQ changed the May 8 closing price to $9.38 per share; and later in the day on May 10, 2012 NASDAQ changed the May 8 closing price back to $9.70 per share. NASDAQ has assured the Company that $9.70 is in fact the correct closing price. Accordingly, the original May 8, 2012 Form 4 was correct.
