Explanation of Responses:
1. These stock options were granted to the Reporting Person pursuant to the Issuer's Director Compensation Plan (the "Plan"). Under the terms of the Plan, the Reporting Person was to receive an award of restricted stock units. Equity granted by Issuer to Reporting Person is held by the Reporting Person on behalf of Oak Investment Partners XII, Limited Partnership ("Oak XII, L.P."). The Oak XII, L.P. partnership agreement does not permit receipt of restricted stock units, and accordingly, the Reporting Person was unable to accept a restricted stock unit grant on behalf of Oak XII, L.P. As permitted under the Plan, these stock options have been granted to Reporting Person in lieu of restricted stock units.
2. The option shall be fully vested and exercisable on the day prior to the Issuer's 2012 annual shareholder meeting (but in no event later than December 31, 2012), subject to Reporting Person's continued services to the Issuer through such date.
3. $0.00 is used for technical reasons as there is no price for this derivative security until exercised.
Executed pursuant to the Limited Power of Attorney for Section 16 Reporting Obligations dated August 27, 2010. Fredric W. Harman is a Director of the Issuer. Mr. Harman is a Managing Member of Oak Associates XII, L.L.C., the General Partner of Oak XII, L.P. Oak XII, L.P. is not reporting a person on this Form 4 because it is not subject to Section 16, as it is not a 10% owner. Each Reporting Person disclaims the existence of a "group" and disclaims beneficial ownership of any securities (except to the extent of such Reporting Person's pecuniary interest in such securities) other than any securities reported herein as being directly owned by such Reporting Person, and this report shall not be deemed an admission that such Reporting Person is the beneficial owner of any such securities for purposes of Section 16 or for any other purpose.
