The foregoing share figures have been provided by the issuer to the offerors and are as of June 19, 2014, the most recent practicable date.

**
The filing fee was calculated in accordance with Rule 0-11 under the Securities Exchange Act of 1934, as amended, and Fee Rate Advisory No. 1 for Fiscal Year 2014, issued August 30, 2013, by multiplying the transaction value by 0.000128800.
