Explanation of Responses:

1. 50,691 Restricted Stock Units ("RSUs") issued in the grant to Dr. Katz on 8/1/2013 vested on 2/1/2015 according to the vesting schedule previously reported.

2. 21,737 shares of Common Stock were withheld by the Company for the purposes of satisfying tax withholding obligations in connection with such vesting as previously reported by the Company.

3. The closing price of the Company's common stock on 2/2/2015.

4. 8,050 RSUs issued in the grant to Dr. Katz on 8/1/2013 vested on 2/1/2015 according to the vesting schedule previously reported.

5. 3,452 shares of Common Stock were withheld by the Company for the purposes of satisfying tax withholding obligations in connection with such vesting as previously reported by the Company.

6. 22,500 RSUs issued in the grant to Dr. Katz on 2/7/2014 vested on 2/1/2015 according to the vesting schedule previously reported.

7. 9,272 shares of Common Stock were withheld by the Company for the purposes of satisfying tax withholding obligations in connection with such vesting as previously reported by the Company.

8. The RSUs vest in seven quarterly installments beginning on November 1, 2013 and ending on May 1, 2015, as previously reported.

9. The RSUs vest as follows: 25% vested on May 1, 2014. The remaining 75% vest in twelve quarterly installments thereafter, beginning on August 1, 2014 and ending on May 1, 2017, as previously reported.

10. The RSUs vest in four quarterly installments beginning on May 1, 2014 and ending on February 1, 2015, as previously reported.

Remarks:

The vesting date of the RSUs was February 1, 2015, as previously reported by the Issuer, which fell on a Sunday this year. Normally the shares will issue on the same date as the vesting date, as reported in the previously filed Form 4s for vesting of RSUs. However, when the vesting date falls on a weekend or federal holiday, due to the normal processing required by the Issuer's transfer agent, it can take up to two business days after the first business day following the vesting date for the resulting shares to be issued. Therefore the shares resulting from the vesting on February 1, 2015 were not issued until February 3, 2015, as reported in this Form 4.
