We did not grant any options under our 2007 Non-Employee Director Stock Compensation Plan ("2007 Director Plan") during the six months ended June 30, 2010. The options granted (i) have an exercise price of not less than 100 percent of the fair market value of the common stock on the grant date, (ii) substantially all become exercisable in four equal installments on the first, second, third and fourth anniversary of the grant date, subject to the employee's continued employment and (iii) expire on the tenth anniversary of the grant date. We did not grant any options to purchase shares of common stock under the 2007 Management Plan or 2007 Director Plan during the six months ended June 30, 2009.</font></div>

The risk-free rate is based on the U.S. Treasury yield curve in effect for the expected term of the options at the time of grant. The dividend yield on our common stock is assumed to be zero since we do not pay dividends and have no current plans to do so. Our historical volatility data and employee stock option exercise patterns were not considered in determining the volatility data and expected life assumptions. The volatility assumptions were based on (i) historical volatilities of the stock of comparable chemical companies whose shares are traded using daily stock price returns equivalent to the expected term of the options and (ii) implied volatility. The expected life of an option was determined based on a simplified assumption that the option will be exercised evenly from the time it becomes exercisable to expiration.</font></div>
