The amount of stock-based compensation recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. Expected forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or “expirations” and represents only the unvested portion of the surrendered option. The Company has applied a forfeiture rate of 9.6% to all unvested options as of September 30, 2010. This estimate is re-evaluated periodically and the forfeiture rate is adjusted as necessary. Ultimately, the actual expense recognized over the vesting period will only be for those shares that vest. </div> <div align="left" style="font-size: 10pt; margin-top: 12pt"><i>Stock Option Award Activity</i> </div> <div align="left" style="font-size: 10pt;
