Explanation of Responses:

1. The reporting person is filing this amendment to report the correct amount of options acquired on June 21, 2013. In a Form 4/A filed on October 20, 2014, the reporting person amended the original Form 4 of June 25, 2013, which reflected the acquisition of options to purchase 8,819 shares pursuant to the Company's Amended and Restated 2000 Stock Option and Incentive Plan (the "Plan), indicating that none of the options were validly granted. However, the Company subsequently determined options to purchase 1,764 shares were validly granted on June 21, 2013.

2. On the Form 4/A filed on October 20, 2014, the amended number of derivative Securities Beneficially Owned of 100,000 (Table II, Box 9) is correct and is not the subject of this amendment. As previously disclosed, the Company determined, subsequent to the filing by the reporting person of the Form 4 of June 25, 2013, that options to purchase 29,514 shares, in aggregate and including the 7,055 shares that are the subject of this amendment, were not validly granted during 2013, pursuant to the Plan, because the grants exceeded the limit on the number of options that may be granted to any individual participant within any calendar year. Accordingly, the attempted grant of these excess options was ineffective, and they were never granted to the reporting person.
