Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) The share issuance reported on Table I reflects shares issued upon the exercise of options granted on May 28, 2008, which, if unexercised, would have expired May 28, 2015. The option exercises are reported on Table II. These option exercises were pursuant to a net issuance arrangement effected under the issuer's equity incentive plan. The number of shares issued pursuant to the net issuance arrangement was calculated as follows: the option exercise price ($4.76) was subtracted from the February 10, 2015 market close price ($35.83) and this net amount ($31.07) was then multiplied by the number of options (7,500), with the resulting amount then divided by the market close price to result in a net issuance of 6,504 shares to the optionee. The 996 shares underlying the remaining portion of the options are not available for reissuance, and no shares are sold into the market as part of the exercise in connection with a net issuance program.
(2) This Form 4/A is being filed to attach the Power of Attorney which was inadvertently ommitted at filing of the Form 4.
