Footnotes

F1: Granted 3/1/2011, under the Company's Amended and Restated 2000 Stock Option and Incentive Plan, vesting over a five year period.

F2: On 6/17/2013, pursuant to the issuer's Offer to Exchange, filed on Schedule TO with the Securities and Exchange Commission on May 17, 2013, the issuer canceled options granted to the reporting person. In exchange, the reporting person was awarded replacement options at an exercise price of $6.29.

F3: As previously reported on the Form 4 filed on June 19, 2013, by the reporting person, the reporting person reported acquiring, on June 17, 2013, stock options to purchase 100,000 shares of common stock pursuant to the issuer's Offer to Exchange. However, the Company subsequently determined that stock options to purchase 30,000 shares of common stock were not validly granted during 2013 pursuant to the Company's Amended and Restated 2000 Stock Option and Incentive Plan because the grants exceeded the limit on the number of stock options that may be granted to any individual participant within any calendar year. Accordingly, the attempted grant of these excess stock options was ineffective, and they were never granted to the reporting person. The reporting person is filing this amendment to report the correct amount of stock options acquired on June 17, 2013.

F4: The replacement options vest over a five year period in equal installments.
